Description

This disclosure relates to a column support and a compression force adjustment plate.

A support mechanism for temporary pillars used when erecting pillars is disclosed, for example, in Japanese Patent Laid-Open Publication No. 2009-13770 (Patent Document 1).

JP 2009-13770 A

The support mechanism for temporary pillars disclosed in Patent Document 1 includes a first box body attached to one end of the pillar and a second box body attached to the other end of the pillar. For example, if you want to install a pillar straight in the vertical direction, and try to install it straight near a side wall of a room, the corners of the box body may come into contact with the ceiling or side wall of the room, risking damaging the ceiling or side wall. This tendency is particularly pronounced when trying to install the pillar material in contact with or close to a side wall. This situation is undesirable, and it is necessary to be able to install it in the desired position, such as close to a side wall, without damaging the ceiling or side wall.

Therefore, one of our goals is to provide a pillar support that can be installed in the desired position while reducing the risk of damaging the wall surface during installation.

A pillar support according to the present disclosure supports a pillar while maintaining tension between opposing first and second wall surfaces. The pillar support includes a first support attached to a first end, which is one end of the pillar in the longitudinal direction, and a second support attached to a second end, which is the other end of the pillar in the longitudinal direction. The first support includes a first contact member that contacts the first wall surface, a first press-fitting member that presses into the first end, and an elastic member that applies elastic force in a direction separating the first press-fitting member from the first contact member. The second support includes a second contact member that contacts the second wall surface and a second press-fitting member that presses into the second end. The pillar support includes a holder that rotatably holds the first press-fitting member so that the distance between the first contact member and the first press-fitting member is variable and the first press-fitting member is tilted relative to the first contact member.

This type of pillar support can be installed in the desired position while reducing the risk of damaging the wall surface during installation.

Description of the embodiments of the present disclosure
First, embodiments of the present disclosure will be described. A column support according to the present disclosure supports a column while maintaining tension between opposing first and second wall surfaces. The column support includes a first support member attached to a first end portion, which is an end portion on one side in the longitudinal direction of the column, and a second support member attached to a second end portion, which is an end portion on the other side in the longitudinal direction of the column. The first support member includes a first contact member that contacts the first wall surface, a first press-fit member that presses into the first end portion, and an elastic member that applies an elastic force in a direction that separates the first press-fit member from the first contact member. The second support member includes a second contact member that contacts the second wall surface and a second press-fit member that presses into the second end portion. The column support includes a holding portion that rotatably holds the first press-fit member so that the distance between the first contact member and the first press-fit member is variable and the first press-fit member is inclined relative to the first contact member.

With a pillar support device configured as described above, when using the pillar support to install a pillar while maintaining tension between the first and second wall surfaces, the holding portion can rotate and tilt the first press-fit member into which the pillar is pressed relative to the first contact member. This allows the first contact member to first contact the first wall surface while the first press-fit member into which the pillar is pressed is tilted. In this state, even if the side wall surface is positioned close to the first wall surface, installation can be performed while reducing the risk of the corners of the first contact member coming into contact with the first wall surface and the side wall surface. The other longitudinal end of the pillar can then be pushed forward to support the pillar while maintaining tension between the first and second wall surfaces. Therefore, this pillar support device can be installed in the desired position while reducing the risk of damaging the wall surface during installation.

In the above-mentioned pillar support, the elastic member may be positioned in a compressed state between the first contact member and the first press-fit member. This reduces the amount of compression that the user must exert when compressing the elastic member during installation. This reduces the effort required by the user during installation, making it easier to install the pillar.

In the above-mentioned pillar support, at least one of the first contact member and the first press-in member may be provided with a mark that indicates the compressed state of the elastic member so that it is visible from the outside before supporting the pillar. This allows the compressed state of the elastic member to be seen from the outside, making it easy to determine whether the compression force when supporting the pillar is appropriate. This can facilitate adjustment of the pillar length to achieve an appropriate compression force, thereby allowing the pillar to be installed more appropriately.

In the above-mentioned pillar support, the mark may be provided on the first press-fit member and may consist of a linear recess extending in a direction intersecting the direction in which the first press-fit member and the first contact member are separated. This not only makes the mark easier to see, but also reduces the risk of interference between the mark and other members. Furthermore, the degree of inclination of the mark during installation can be visually determined, allowing for more appropriate pillar installation.

In the above-mentioned pillar support, the holding portion may include a protrusion provided on the first press-fitting member. The protrusion may be solid cylindrical and protrude in a direction perpendicular to the direction in which the first press-fitting member and the first contact member are separated. The holding portion may include a guide rib provided on the first contact member that receives the protrusion and restricts its movement. In this manner, the protrusion included in the holding portion and provided on the first press-fitting member, and the guide rib included in the holding portion and provided on the first contact member, can rotatably hold the first press-fitting member so as to more appropriately tilt the first press-fitting member. This allows the pillar to be installed more appropriately.

In the above-mentioned column support, the protrusion may include a first tip region located on the first contact member side in the direction in which the first press-fit member and the first contact member are separated. The first tip region may be an inclined surface that slopes so that the protrusion increases in amount from the side closer to the first contact member to the side farther from it. In this way, the first tip region can be used to more smoothly engage the protrusion with the guide rib.

In the above-mentioned pillar support, the holding portion may include multiple protrusions. The holding portion may also include multiple guide ribs that receive the multiple protrusions. This allows the first press-in member, into which the pillar is press-fitted, to be tilted more stably in the first direction. This allows for more reliable installation in the desired position while reducing the risk of damaging the wall surface during installation.

In the above-mentioned pillar support, the elastic member may be a compression spring with a spring constant of 1 N/mm or more and 5 N/mm or less. This allows the tension applied between the wall surfaces to be within an appropriate range.

The column support may further include a plate-shaped compression force adjustment plate having a compression force adjustment protrusion formed on one thickness-wise surface and a flat surface on the other thickness-wise surface. The second press-fitting member may include a mounting surface on which the compression force adjustment plate is placed. The mounting surface may be formed with a flat surface and a compression force adjustment recess that receives the compression force adjustment protrusion. This allows the longitudinal length of the column to be easily adjusted using the compression force adjustment plate, making it easier to support the column with appropriate tension.

The pillar support of the present disclosure supports a pillar while maintaining tension between opposing first and second wall surfaces. The pillar support includes a first support attached to a first end, which is one longitudinal end of the pillar. The first support includes a first contact member that contacts the first wall surface, a first press-fit member that presses into the first end, and an elastic member that applies an elastic force in a direction that separates the first press-fit member and the first contact member. The elastic member is positioned between the first contact member and the first press-fit member in a compressed state.

This type of pillar support reduces the effort required of the user during installation, making it easier to install pillars.

The pillar support of the present disclosure supports a pillar while maintaining tension between opposing first and second wall surfaces. The pillar support includes a first support attached to a first end, which is one longitudinal end of the pillar. The first support includes a first contact member that contacts the first wall surface, a first press-fit member that presses into the first end, and an elastic member that applies an elastic force in a direction that separates the first press-fit member from the first contact member. The pillar support includes a holder that allows the distance between the first contact member and the first press-fit member to be variable and rotatably holds the first press-fit member so that the first press-fit member can be tilted relative to the first contact member.

This type of pillar support can be installed in the desired position while reducing the risk of damaging the wall surface during installation.

The compression force adjustment plate of the present disclosure is used in a pillar support that supports a pillar while maintaining tension between opposing first and second wall surfaces. The compression force adjustment plate has a compression force adjustment protrusion formed on one surface in the thickness direction, and includes a flat surface on the other surface in the thickness direction.

This type of compression force adjustment plate makes it easy to adjust the longitudinal length of the pillar material, making it easier to support the pillar material with appropriate tension.

[Details of the embodiment of the present disclosure]
Next, an embodiment of a pole support of the present disclosure will be described with reference to the drawings. In the following drawings, the same or corresponding parts are designated by the same reference numerals, and the description thereof will not be repeated.

(Embodiment 1)
A pillar support according to a first embodiment of the present disclosure will be described. FIG. 1 is an exploded perspective view of the pillar support according to the first embodiment. FIG. 2 is a perspective view showing the exterior of the pillar support according to the first embodiment. FIG. 3 is a front view of the pillar support shown in FIG. 2. FIG. 4 is a side view of the pillar support shown in FIG. 2. FIG. 5 is a plan view of the pillar support shown in FIG. 2. FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 4. In this embodiment, the longitudinal direction (height direction) of the installed pillar is defined as the Z direction, the vertical direction of the cross section of the pillar perpendicular to the Z direction is defined as the X direction, and the horizontal direction of the cross section of the pillar is defined as the Y direction. In other words, the pillar is supported in the Z direction by the pillar support. The X direction, Y direction, and Z direction are all orthogonal to each other. In FIG. 1 and other figures, the longitudinal length of the pillar is omitted. Furthermore, in this specification, the X direction, Y direction, and Z direction indicate the directions when a column is supported between the opposing first wall surface, which is the ceiling wall surface, and the second wall surface, which is the floor wall surface, and when explaining the parts that make up the column support, for convenience, they are shown as the directions when the column is supported.

Referring to Figures 1 to 6, the column support 11 in embodiment 1 includes a first support member 13, a second support member 14, and compression force adjustment plates 29a and 29b. The configuration of the compression force adjustment plates 29a and 29b will be described in detail later. The column support 11 is used to support a column 12. The column 12 supported by the column support 11 has a rectangular cross-sectional shape when cut in a cross section perpendicular to the longitudinal direction of the column 12 (the X-Y cross section when installed). In this embodiment, the column support 11 is made of square timber, specifically, a wooden timber with a square cross-sectional shape. One example of a specific column 12 is a two-by-four lumber. Depending on the application and needs, the column support 11 may have a shape corresponding to one-by-four lumber, two-by-six lumber, or any other shape corresponding to lumber with any desired vertical and horizontal lengths.

The pillar support 11 supports the pillar 12 while maintaining tension between a first wall surface and a second wall surface that face each other in a first direction. Specifically, for example, the pillar support 12 supports the pillar 12 while maintaining tension between the ceiling surface (first wall surface) of a room and the floor surface (floor surface) of the room that face each other in the vertical direction (first direction). This will be described later. The pillar support 11 is made of resin, except for the compression springs 22a and 22b (described later), which are made of metal. Specifically, the first pad portion 25 and the second pad portion 27 (described later) are made of EVA (Ethylene-Vinyl Acetate) resin. With the exception of the compression springs 22a, 22b, the first pad portion 25, and the second pad portion 27, the materials that make up the column support 11 are ABS (Acrylonitrile Butadiene Styrene) resin. Of course, these resin materials are not limited to those mentioned above.

Next, the specific configuration of the first support member 13 will be described. The first support member 13 is attached to the first end portion 16a, which is one longitudinal end portion of the pillar member 12. When supporting the pillar member 12, the first support member 13 is positioned so that it is located on the vertically upper side, i.e., the ceiling wall surface side. The first support member 13 includes a first press-fit member 21, two compression springs 22a and 22b, which are elastic members, and a first contact member 23. The first contact member 23 includes a cover portion 24 and a first pad portion 25. In this embodiment, the first contact member 23 is separably provided as the cover portion 24 and the first pad portion 25. Note that the first contact member 23 may be configured as a single unit. The compression springs 22a and 22b apply elastic force in a direction that separates the first press-fit member 21 and the first contact member 23.

Here, the column support 11 includes a holding portion 38 that rotatably holds the first press-fit member 21 so that the distance between the first contact member 23 and the first press-fit member 21 is variable and the first press-fit member 21 is tilted relative to the first contact member 23. This will be described later. Note that the direction in which the first press-fit member 21 and the first contact member 23 move apart is the first direction, the Z direction, in the state shown in Figures 1 to 6.

Next, the configuration of the first press-fitting member 21 will be described. Figures 7 and 8 are enlarged schematic perspective views of the first press-fitting member 21. Figures 7 and 8 illustrate the first press-fitting member 21 at different angles. Referring to Figures 7 and 8 together, the first press-fitting member 21 includes an annular first side wall portion 31, an annular second side wall portion 32, and a flat plate portion 33. The flat plate portion 33 is positioned so as to cover one opening of the annular first side wall portion 31 and the other opening of the annular second side wall portion 32.

A space 35 is formed within the first side wall 31, which has an opening 34 in the Z direction. The space 35 is an area surrounded by the flat plate portion 33 and the first side wall 31. The shape of the opening 34 in the first side wall 31 is rectangular when viewed in the Z direction, and is the same as a cross section perpendicular to the longitudinal direction of the pillar 12. When attaching the first press-fit member 21 to the pillar 12, the first longitudinal end 16a of the pillar 12 is press-fitted into the space 35.

The inner surface 36 of the first side wall portion 31 is provided with a plurality of first protrusions 37 extending in the Z direction, spaced apart in the X and Y directions. In this embodiment, a total of four first protrusions 37 are provided on the inner surface 36 facing in the X direction. The amount of protrusion of the first protrusions 37 from the inner surface 36 decreases from midway in the Z direction toward the opening 34. When the first end 16a of the pillar 12 is press-fitted, the first protrusions 37 bite into the side surface of the pillar 12, maintaining a strong press-fit state of the pillar 12. In other words, this configuration suppresses rattle of the pillar 12 after it has been press-fitted.

A space 42 is formed in the second side wall portion 32, which has an opening 41 in the Z direction. The space 42 is an area surrounded by the flat plate portion 33 and the second side wall portion 32. The shape of the opening 41 in the second side wall portion 32 is also rectangular when viewed in the Z direction. The shape of the opening 41 is smaller than the shape of the opening 34. Specifically, the length of the opening 41 in the vertical direction (X direction) is shorter than the length of the opening 34 in the vertical direction. Furthermore, the length of the opening 41 in the horizontal direction (Y direction) is shorter than the length of the opening 34 in the horizontal direction.

Compression springs 22a and 22b are housed within space 42. Two first retaining protrusions 43a and 43b are provided within space 42, holding portions of compression springs 22a and 22b. Each of the first retaining protrusions 43a and 43b is hollow and cylindrical, and is spaced apart in the Y direction. The first retaining protrusions 43a and 43b are formed to extend in the Z direction from the flat plate portion 33. The inner diameters of the first retaining protrusions 43a and 43b are large enough to house compression springs 22a and 22b, respectively. The first retaining protrusions 43a and 43b are arranged so that portions of the compression springs 22a and 22b in the Z direction are housed within the first retaining protrusions 43a and 43b. When compression springs 22a and 22b are housed within the first retaining protrusions 43a and 43b, respectively, one end of each compression spring 22a and 22b in the Z direction (the end facing opposite to the arrow Z) is in contact with the flat plate portion 33.

Two protrusions 45a, 45b serving as the retaining portion 38 are formed on the outer surface 44 of the second side wall portion 32. The protrusions 45a, 45b are each provided to protrude in the Y direction. The protrusions 45a, 45b are each provided to protrude in the Y direction from the outer surface 44 of the second side wall portion 32. The outer shape of the protrusion 45a is round when viewed in the Y direction. In other words, the side surface 46a of the protrusion 45a is arc-shaped. The center of the round shape of the protrusion 45a serves as the center of rotation.

The protrusion 45a includes a first tip region 47a located on the first contact member 23 side in the direction (Z direction) in which the first press-fit member 21 and the first contact member 23 are separated from each other. In this embodiment, the protrusion 45a further includes a second tip region 48a and a third tip region 49a. The third tip region 49a is located on the flat plate portion 33 side in the Z direction. The second tip region 48a is located on the opening 41 side, i.e., the first contact member 23 side, relative to the third tip region 49a in the Z direction. The second tip region 48a is located between the first tip region 47a and the third tip region 49a in the Z direction. The third tip region 49a is a plane parallel to the X-Z plane. The second tip region 48a is an arcuate surface that smoothly continues from the first tip region 47a toward the third tip region 49a. That is, when viewed from the X direction, the second tip region 48a appears as an arcuate surface. The first tip region 47a is a flat surface. Here, the first tip region 47a is an inclined surface that slopes so that the amount of protrusion of the protrusion 45 increases from the side closer to the first contact member 23 to the side farther from it. The protrusion 45b has a similar configuration.

A mark 39 indicating the compressed state of the compression springs 22a, 22b is formed on the outer surface 44 of the second side wall portion 32. That is, the mark 39 is provided on the first press-fit member 21. The mark 39 is provided in a region of the outer surface 44 located in the X direction. The mark 39 is provided in the central region in the Y direction so as to extend in the Y direction. The mark 39 is formed so as to be recessed in a groove shape from the outer surface 44. In this embodiment, the mark 39 is configured as a linear recess extending in a direction intersecting the Z direction, which is the direction in which the first press-fit member 21 and the first contact member 23 are separated from each other, specifically, in the Y direction perpendicular to the Z direction. The mark 39 is provided so as to be visible from the outside before supporting the pillar material 12. Specifically, the mark 39 is provided in a position in the Z direction that is exposed in the X direction when the cover portion 24 is fitted into the first press-fit member 21 as described below.

The first contact member 23 includes a cover portion 24 and a first pad portion 25. Next, the configuration of the cover portion 24 will be described. Figures 9 and 10 are enlarged schematic perspective views of the cover portion 24. Figures 9 and 10 illustrate the cover portion 24 from different angles. Referring to Figures 9 and 10 together, the cover portion 24 has a space 54 with an opening 53 in the Z direction. The cover portion 24 includes a bottom plate portion 51 and a side wall portion 52. The space 54 is an area surrounded by the bottom plate portion 51 and the side wall portion 52. A plurality of protruding guide portions 56 extending in the Z direction are formed on the inner surface 55 of the side wall portion 52, spaced apart in the X and Y directions. A portion of the second side wall portion 32 of the first press-fit member 21 is positioned within the space 54. When the second side wall portion 32 is inserted into the space 54, the position in the X direction is guided by the plurality of protruding guide portions 56.

Like the openings 34 and 41 described above, the shape of the opening 53 in the cover portion 24 is rectangular when viewed in the Z direction. The shape of the opening 53 is larger than the shape of the opening 41. Specifically, the vertical length (X direction) and horizontal length (Y direction) of the opening 41 are shorter than the vertical length and horizontal length of the opening 34, respectively. In this embodiment, the size of the opening 53 is the same as the size of the opening 34.

The bottom plate portion 51 of the cover portion 24 is provided with two second holding protrusions 57a, 57b that protrude toward the space 54 in the Z direction. The second holding protrusions 57a, 57b have portions that protrude hemispherically from the bottom plate portion 51. The second holding protrusions 57a, 57b are spaced apart in the Y direction.

The second retaining protrusions 57a and 57b are housed in the compression springs 22a and 22b, respectively. By housing the compression springs 22a and 22b within the other ends of the second retaining protrusions 57a and 57b, respectively, it is possible to prevent the compression springs 22a and 22b from shifting position when compressed. In other words, the second retaining protrusions 57a and 57b can function as guides for the compression springs 22a and 22b when they are compressed.

The cover portion 24 is formed with multiple first fitting protrusions 58a, 58b, 58c, 58d, 58e, 58f, 58g, and 58h that protrude from the bottom plate portion 51 on the side opposite the space 54 in the Z direction. In this embodiment, eight first fitting protrusions 58a-58h are provided, spaced apart in both the X and Y directions. These first fitting protrusions 58a-58h are used when attaching the first pad portion 25 to the cover portion 24.

The retaining portion 38 includes guide ribs 61a and 61b that are provided on the first contact member 23, specifically the cover portion 24, and that receive the protrusions 45a and 45b and restrict their movement. The guide rib 61a guides the protrusions 45a and 45b provided on the second side wall portion 32 of the first press-fitting member 21. The guide ribs 61a and 61b each protrude from the inner surface 55 of the side wall portion 52. One guide rib 61a includes a first convex portion 62a, a second convex portion 63a, a third convex portion 64a, and a fourth convex portion 65a. The first convex portion 62a and the second convex portion 63a each extend in the Z direction from the opening 53 toward the bottom plate portion 51. The first convex portion 62a and the second convex portion 63a are spaced apart in the X direction. The third convex portion 64a extends in the X direction from the first convex portion 62a toward the second convex portion 63a. The protrusion 45a is accommodated in an area 66a partitioned by the first convex portion 62a, the second convex portion 63a, and the third convex portion 64a. The fourth convex portion 65a extends in the Z direction from the opening 53 toward the third convex portion 64a. The fourth convex portion 65a is tapered such that the distance from the inner surface 55 is shortest on the opening 53 side in the Z direction and increases as it approaches the third convex portion 64a. The other guide rib 61b has a similar configuration.

Next, the configuration of the first pad portion 25 will be described. The first pad portion 25 is plate-shaped. One surface of the first pad portion 25 in the thickness direction is flat. The first pad portion 25 has cushioning properties compared to the cover portion 24. The external shape of the first pad portion 25 is rectangular when viewed in the thickness direction (Z direction), and is a shape that follows the external shape of the cover portion 24. The first pad portion 25 is the portion that contacts the top wall surface, which is the first wall surface. Specifically, the first pad portion 25 is installed so that one surface of the first pad portion 25 in the thickness direction contacts the top wall surface. The first pad portion 25 is made of a material that is non-slip on the top wall surface. The first pad portion 25 is attached to the cover portion 24. Specifically, the other thickness-wise surface of the first pad portion 25 is provided with eight first fitting recesses at positions corresponding to the eight first fitting protrusions 58a, 58b, 58c, 58d, 58e, 58f, 58g, and 58h provided on the cover portion 24. Each of the first fitting recesses is a cylindrical member with a recessed portion corresponding to the first fitting protrusions 58a to 58h. The first pad portion 25 is attached to the cover portion 24 by fitting the first fitting protrusions 58a to 58h into the first fitting recesses provided at positions corresponding to the eight first fitting protrusions 58a to 58h.

Compression springs 22a and 22b have a spring constant of 1 N/mm or more and 5 N/mm or less. In other words, if the spring constant is 1 N/mm, a force of 1 N is required to compress one compression spring 22a by 1 mm. In this embodiment, two compression springs 22a and 22b are used, and if each spring constant is 3 N/mm, a total force of 6 N is required to compress the first support 13 by 1 mm in the longitudinal direction (Z direction) when it is attached to the pillar material.

Next, the assembly of the first support body 13 will be described. The first support body 13 is assembled using the first contact member 23, which includes the first press-fit member 21 configured as described above, two compression springs 22a and 22b, a cover portion 24, and a first pad portion 25. Specifically, one end of each of the compression springs 22a and 22b is housed inside the hollow, cylindrical first holding protrusions 43a and 43b of the first press-fit member 21. Next, the other end of each of the compression springs 22a and 22b is held by the second holding protrusions 57a and 57b, and the cover portion 24 is attached to the first press-fit member 21 by compressing the compression springs 22a and 22b.

When compressing, the protrusion 45a, which has a second tip region 48a, can be compressed more smoothly along the fourth convex portion 65a of the guide rib 61a. This reduces the risk of interference between the protrusion 45a and the third convex portion 64a of the guide rib 61a. The protrusion 45a avoids the third convex portion 64a and is positioned within the region 66a of the guide rib 61a. At this time, the compression springs 22a and 22b are compressed with a certain degree of compressive force, but the protrusions 45a and 45b are engaged with the third convex portion 64a. The same applies to the relationship between the protrusion 45b and the guide rib 61b. In this way, the compression springs 22a and 22b apply elastic force in a direction that separates the first press-fit member 21 and the first contact member 23. By adopting this configuration of the retaining portion 38, the risk of the cover portion 24 falling off from the second side wall portion 32 of the first press-fitting member 21 can be greatly reduced. The first fitting protrusions 58a-58h are then fitted into the first fitting recesses to attach the first pad portion 25 to the cover portion 24. In this manner, the first support body 13 is assembled. Note that the first pad portion 25 may be attached to the cover portion 24 first, and then the cover portion 24 may be attached to the first press-fitting member 21.

Next, the specific configuration of the second support 14 will be described. The second support 14 is attached to the other longitudinal side of the pillar 12. When supporting the pillar 12, the second support 14 is positioned so that it is located on the floor side. The second support 14 includes a second press-fit member 26 and a second pad portion 27. In this embodiment, the second support 14 is configured to include the second press-fit member 26 and the second pad portion 27 as a separate member, but the second support 14 may also be configured as an integrated product. In other words, the second press-fit member 26 and the second pad portion 27 may be formed as an integrated unit.

First, the configuration of the second press-fit member 26 will be described. Figures 11 and 12 are enlarged, schematic perspective views of the second press-fit member 26. Figures 11 and 12 show the second press-fit member 26 from different angles. Figure 13 is a plan view of the second press-fit member 26 shown in Figures 11 and 12. Figure 14 is a cross-sectional view of the second press-fit member 26 shown in Figures 11 and 12, taken along the cross section indicated by arrow XIV-XIV in Figure 13. For ease of understanding, Figure 14 shows the second pad portion 27 attached to the second press-fit member 26.

Referring also to Figures 11 to 14, the second press-fitting member 26 has a space 74 with an opening 73 in the Z direction. The second press-fitting member 26 includes a bottom plate portion 71 and a side wall portion 72. The space 74 is an area surrounded by the bottom plate portion 71 and the side wall portion 72. When attaching the second press-fitting member 26 to the pillar 12, the second end portion 16b, which is the other longitudinal end portion of the pillar 12, is press-fitted into the space 74.

The inner surface 75 of the side wall portion 72 is provided with a plurality of second protrusions 76a, 76b, 76c, and 76d extending in the Z direction, spaced apart in the X and Y directions. In this embodiment, a total of four second protrusions 76a-76d are provided on the inner surface 75 facing in the X direction. The amount of protrusion of the second protrusions 76a-76d from the inner surface 75 decreases from midway in the Z direction toward the opening 73. When the second end 16b of the pillar 12 is press-fitted, the second protrusions 76a-76d bite into the side surface of the pillar 12, maintaining a tight press-fit state of the pillar 12. In other words, this configuration reduces rattling of the pillar 12 after it is press-fitted.

The second press-fitting member 26 is formed with multiple second fitting protrusions 78a, 78b, 78c, 78d, 78e, 78f, 78g, and 78h that protrude from the bottom plate portion 71 on the side opposite the space 74 in the Z direction. In this embodiment, eight second fitting protrusions 78a to 78h are provided, spaced apart in both the X and Y directions. These second fitting protrusions 78a to 78h are used when attaching the second pad portion 27 to the second press-fitting member 26. The specific configuration of the bottom plate portion 71 will be described in more detail later.

Next, the configuration of the second pad portion 27 will be described. Figure 15 is a schematic perspective view showing an enlarged view of the second pad portion 27. Referring also to Figure 15, the second pad portion 27 is plate-shaped. The outer shape of the second pad portion 27 is rectangular when viewed in the thickness direction (Z direction), and is a shape that follows the outer shape of the second press-fit member 26. The second pad portion 27 is the portion that contacts the floor wall surface (floor surface). Specifically, the second pad portion 27 is installed so that one surface in the thickness direction of the second pad portion 27 contacts the floor wall surface. The one surface in the thickness direction of the second pad portion 27 is flat. The second pad portion 27 has cushioning properties. The second pad portion 27 is made of a material that is non-slip on the floor wall surface. The second pad portion 27 is attached to the second press-fit member 26. Specifically, the other surface of the second pad portion 27 in the thickness direction is provided with eight second fitting recesses 28a, 28b, 28c, 28d, 28e, 28f, 28g, and 28h, which are provided at positions corresponding to the eight second fitting protrusions 78a, 78b, 78c, 78d, 78e, 78f, 78g, and 78h provided on the second press-fitting member 26. The second fitting recesses 28a to 28h are each formed by recessing a portion of a cylindrical member corresponding to the second fitting protrusions 78a to 78h. The second pad portion 27 is attached to the second press-fitting member 26 by fitting the second fitting protrusions 78a to 78h into the second fitting recesses 28a to 28h, which are provided at positions corresponding to the eight second fitting protrusions 78a to 78h. In the second pad portion 27, one surface in the thickness direction that does not have the second fitting recesses 28a-28h is the surface that comes into contact with the floor wall surface.

Next, the configuration of the compression force adjustment plate 29a will be described. Figures 16 and 17 are enlarged schematic perspective views of the compression force adjustment plate 29a. Figures 16 and 17 each illustrate the compression force adjustment plate 29a at different angles. Figure 18 is a plan view of the compression force adjustment plate 29a. Figure 19 is a bottom view of the compression force adjustment plate 29a. Figure 20 is a front view of the compression force adjustment plate 29a. Figure 21 is a right side view of the compression force adjustment plate 29a. The rear view of the compression force adjustment plate 29a is omitted because it is symmetrical to the front view of the compression force adjustment plate 29a shown in Figure 20. Furthermore, the left side view of the compression force adjustment plate 29a is omitted because it is symmetrical to the right side view of the compression force adjustment plate 29a shown in Figure 21.

Referring also to Figures 16 to 21, the compression force adjustment plate 29a is used in a pillar support 11 that supports a pillar 12 while maintaining tension between opposing first and second wall surfaces. The compression force adjustment plate 29a adjusts the compression force of the compression springs 22a and 22b, which are elastic members. Specifically, when the pillar support 11 is attached to the pillar 12, the compression force of the compression springs 22a and 22b is adjusted by adjusting the longitudinal length (height) of the pillar 12. The compression force adjustment plate 29a is plate-shaped. The compression force adjustment plate 29a includes a first surface 91a located on one side in the thickness direction and a second surface 92a located on the other side in the thickness direction. The outer shape of the compression force adjustment plate 29a is rectangular when viewed in the thickness direction (Z direction). Specifically, the outer shape of the compression force adjustment plate 29a, when viewed in the Z direction, conforms to the inner surface 75 of the side wall portion 72 that defines the space 74 of the second press-fitting member 26. The compression force adjustment plate 29a can be stacked on the bottom plate portion 71 of the second press-fitting member 26 in the Z direction.

The first surface 91a is provided with compression force adjustment protrusions 93a, 94a, and 95a that protrude in the thickness direction and are used to adjust the compression force. Each of the compression force adjustment protrusions 93a, 94a, and 95a is ridge-shaped and extends in the X direction. Each of the compression force adjustment protrusions 93a, 94a, and 95a is formed to protrude in the thickness direction (Z direction). Each of the compression force adjustment protrusions 93a, 94a, and 95a is provided with a gap in the Y direction. The top surface of each of the compression force adjustment protrusions 93a, 94a, and 95a in the Z direction is a plane parallel to the X-Y plane. The second surface 92a is provided with three recesses 96a, 97a, and 98a recessed in the thickness direction from the second surface 92a at positions corresponding to the compression force adjustment protrusions 93a, 94a, and 95a. The recesses 96a, 97a, and 98a are each divided at the center in the X direction. That is, the recesses 96a, 97a, and 98a are each divided in the X direction. Furthermore, the areas of the second surface 92a other than the areas where the recesses 96a, 97a, and 98a are provided are flat surfaces 99a. That is, the second surface 92a includes a flat surface 99a parallel to the X-Y plane. The compression force adjustment plate 29a has compression force adjustment protrusions 93a, 94a, and 95a formed on the first surface 91a, which is one surface in the thickness direction, and includes a flat surface 99a on the second surface 92a, which is the other surface in the thickness direction.

Next, the specific configuration of the bottom plate portion 71 will be described with particular reference to Figures 13 and 14. The bottom plate portion 71 includes a mounting surface 79 on which the compression force adjusting plate 29a can be placed, on the side facing the space 74 in the thickness direction. The bottom plate portion 71 includes compression force adjustment recesses 81a, 82a, and 83a that are provided at positions corresponding to the compression force adjustment protrusions 93a, 94a, and 95a when the compression force adjusting plate 29a is arranged so that the mounting surface 79 and the first surface 91a face each other, and that receive the compression force adjustment protrusions 93a, 94a, and 95a. Furthermore, the bottom plate portion 71 includes flat surfaces 84a, 85a, 86a, and 87a that are arranged adjacent to the compression force adjustment recesses 81a, 82a, and 83a and that come into contact with the flat surface 99a of the second surface 92a when the compression force adjusting plate 29a is arranged so that the mounting surface 79 and the second surface 92a face each other. That is, the second press-fitting member 26 includes the mounting surface 79 on which the compression force adjusting plate 29a is placed, and the mounting surface 79 is formed with the flat surfaces 84a, 85a, 86a, and 87a and the compression force adjustment recesses 81a, 82a, and 83a that receive the compression force adjustment protrusions 93a, 94a, and 95a. The height _H1 in the Z direction from the second pad portion 27 to the flat portions 84a, 85a, 86a, and 87a is the height from the second pad portion 27 to the bottom plate portion 71 when the compression force adjusting plates 29a and 29b are not arranged.

The configuration of the compression force adjustment plate 29b is similar to that of the compression force adjustment plate 29a, and therefore its description will be omitted. In other words, in this embodiment, the column support 11 is configured to include two compression force adjustment plates 29a, 29b with the same configuration.

Next, the assembly of the second support body 14 will be described. First, the compression force adjusting plates 29a, 29b are placed in the space 74 of the second press-fitting member 26. In this case, the compression force adjusting plate 29a is placed so that the mounting surface 79 of the bottom plate portion 71 faces the first surface 91a of the first compression force adjusting plate 29a. Figure 22 is a plan view of the compression force adjusting plate 29a placed on the mounting surface 79. Figure 23 is a cross-sectional view taken along line XXIII-XXIII in Figure 22. 22 and 23 , when the compression force adjusting plate 29a is placed on the mounting surface 79, the compression force adjusting recesses 81a, 82a, and 83a are shaped to receive the compression force adjusting protrusions 93a, 94a, and 95a. Therefore, the compression force adjusting protrusions 93a, 94a, and 95a are fitted into the compression force adjusting recesses 81a, 82a, and 83a. In this case, the compression force adjusting protrusions 93a, 94a, and 95a each face toward the second pad portion 27 in the Z direction. The height of the compression force adjusting plate 29a from the second pad portion 27 in the Z direction can be changed to a height _H2 different from the height _H1 . In other words, the compression force adjusting plate 29a can increase the height of the bottom plate portion 71 by the thickness of the compression force adjusting plate 29a.

Next, the second compression force adjusting plate 29b is placed on the first compression force adjusting plate 29a. FIG. 24 is a plan view of the second compression force adjusting plate 29b placed on the first compression force adjusting plate 29a. FIG. 25 is a cross-sectional view taken along line XXV-XXV in FIG. 24. Referring to both FIGS. 24 and 25, the second compression force adjusting plate 29b is placed on the first compression force adjusting plate 29a so that the second surface 92a of the first compression force adjusting plate 29a faces the second surface 92b of the second compression force adjusting plate 29b. In this case, the compression force adjusting protrusions 93b, 94b, and 95b each face away from the second pad portion 27 in the Z direction. The height in the Z direction from the second pad portion 27 to the compression force adjusting plate 29b can be changed to a height _H3 different from the heights _H1 and H2. In this way, the second compression force adjusting plate 29b can increase the height of the bottom plate portion 71 by the thickness of the compression force adjusting plate 29b as well as the heights of the compression force adjusting protrusions 93b, 94b, and 95b of the compression force adjusting plate 29b. In this way, the height of the bottom plate portion 71 is adjusted, and thus the compression forces of the compression springs 22a and 22b, which are elastic members, are adjusted.

Next, we will explain how to install a pillar 12 between a ceiling wall surface and a floor wall surface using a pillar support 11 including such a first support 13 and second support 14. First, the first support 13 assembled as described above is attached to the first end 16a of the pillar 12. Then, the second support 14 assembled as described above is attached to the second end 16b of the pillar 12. The order in which the first support 13 and second support 14 are attached to the pillar 12 does not matter. In this way, the first support 13 attached to the pillar 12 can compress the compression springs 22a, 22b by applying a force in the Z direction. Note that the mark 39 on the second side wall portion 32 can be seen from the outside (in this case, the X direction) when a weak compression force is applied, but cannot be seen from the outside when a strong compression force is applied.

Next, the first contact member 23 of the pillar 12 to which the first support 13 and second support 14 are attached is brought into contact with the ceiling wall surface and side wall surface. Figure 26 is a side view of the first contact member 23 in contact with the ceiling wall surface and side wall surface. Figure 27 is a perspective view of the first contact member 23 in contact with the ceiling wall surface and side wall surface. Figure 28 is a front view of the first contact member 23 in contact with the ceiling wall surface and side wall surface. Figure 29 is a cross-sectional view taken along line XXIX-XXIX in Figure 28.

Referring also to Figures 26 to 29, the first support 13 is positioned with the attached side facing vertically upward, so that the first contact member 23 comes into contact with each of the ceiling wall surface 17 and the side wall surface 18. Here, the column support 11 includes a holder 38 that rotatably holds the first press-fit member 21 so that the distance between the first contact member 23 and the first press-fit member 21 is variable and the first press-fit member 21 is tilted relative to the first contact member 23. Therefore, the state shown in Figures 26 to 29 can be achieved. That is, when the column support 11 is used to install the column 12 between the ceiling wall surface 17, which is the first wall surface, and the floor wall surface 19, which is the second wall surface, while maintaining tension, the holder 38 allows the first press-fit member 21, into which the column 12 is press-fitted, to be rotated and tilted relative to the first contact member 23. This allows the first contact member 23 to first contact the top wall surface 17, which is the first wall surface, with the first press-fit member 21 into which the pillar 12 is press-fitted, while being tilted. In this state, even if the side wall surface 18 is positioned close to the top wall surface 17, installation can be performed while reducing the risk of the corners of the first contact member 23 coming into contact with the top wall surface 17 and the side wall surface 18. That is, the region of the first press-fit member 21 into which the pillar 12 is press-fitted can be tilted relative to the Z direction, allowing the first contact member 23 to be pressed against the top wall surface 17 and the side wall surface 18 first. Because the region of the first press-fit member 21 into which the pillar 12 is press-fitted is tilted relative to the Z direction, the risk of the corners of the first contact member 23 coming into contact with and damaging the top wall surface 17 or the side wall surface 18 is significantly reduced.

Thereafter, the second end 16b of the pillar 12 on the other longitudinal side can be pushed forward in the direction indicated by arrow _D1 , thereby supporting the pillar 12 while maintaining tension between the ceiling wall surface 17 and the floor wall surface 19. Therefore, such a pillar support 11 can be installed in a desired position while reducing the risk of damaging the wall surface during installation.

FIG. 30 is a front view of a column support 11 supporting a column 12 installed between a ceiling wall surface and a floor wall surface. FIG. 31 is a cross-sectional view of the column 12 shown in FIG. 30 and the column support 11 supporting the column 12. FIG. 31 corresponds to the cross-section shown in FIG. 6. Referring to both FIGS. 30 and 31 , the column 12 supported by the column support 11 while maintaining tension between the ceiling wall surface 17 and the floor wall surface 19 is installed so as to extend straight in the vertical direction. Here, the mark 39 provided on the first press-fit member 21 is hidden by the first contact member 23 and is exposed just enough to be visible when viewed from the X direction. If the column 12 is supported in this state, it can be determined that the compressive force used to support the column 12 is appropriate. Note that if the column support 11 is used to support the column 12, if the mark 39 is easily visible, it can be determined that the compressive force is insufficient. Therefore, by adjusting the longitudinal height of the pillar material 12 and using the compression force adjusting plates 29a, 29b, for example, by adopting the arrangement of the compression force adjusting plates 29a, 29b shown in Figure 33 described later, the compression force can be adjusted from height _H3 to height _H5 so that the mark 39 is just barely visible. On the other hand, if the mark 39 is completely invisible, it can be recognized that the compression force is too strong. In this case, by removing one or both of the compression force adjusting plates 29a, 29b, the compression force can be adjusted to height _H1 shown in Figure 14, height _H2 shown in Figure 23, or even height _H4 shown in Figure 32 described later so that the mark 39 is just barely visible.

As described above, with this configuration, when using the column support 11 to install the column 12 while maintaining tension between the first and second wall surfaces, the holding portion 38 can rotate and tilt the first press-fit member 21 into which the column 12 is press-fit relative to the first contact member 23. In this way, the first press-fit member 21 into which the column 12 is press-fit can be tilted and the first contact member 23 can be brought into contact with the first wall surface first. In this state, even if a side wall surface is positioned close to the first wall surface, installation can be performed while reducing the risk of the corners of the first contact member 23 coming into contact with the first wall surface and the side wall surface. The other longitudinal end of the column 12 can then be pushed forward to support the column 12 while maintaining tension between the first and second wall surfaces. Therefore, this column support 11 can be installed in the desired position while reducing the risk of damaging the wall surface during installation. In other words, this type of pillar support 11 can support the pillar 12 with an appropriate tension force, reduce the risk of damaging the wall surface during installation, and allow it to be installed in the desired position.

In this embodiment, the compression springs 22a and 22b, which are elastic members, are positioned in a compressed state between the first contact member 23 and the first press-fit member 21. Therefore, during installation, the user can reduce the amount of compression required when compressing the compression springs 22a and 22b. This reduces the effort required by the user during installation, making it easier to install the pillar material 12.

In this embodiment, the first press-fit member 21 is provided with marks 39 that indicate the compressed state of the compression springs 22a, 22b so that they are visible from the outside before supporting the pillar 12. This makes it possible to grasp the compressed state of the compression springs 22a, 22b from the outside, and easily determine whether the compression force when supporting the pillar 12 is appropriate. This facilitates adjustment of the length of the pillar 12 so that the compression force is appropriate. This allows the pillar 12 to be installed more appropriately.

In this embodiment, the mark 39 is provided on the first press-fit member 21 and consists of a linear recess that extends in a direction that intersects with the direction in which the first press-fit member 21 and the first contact member 23 are separated from each other. This not only makes the mark 39 easier to see, but also reduces the risk of interference between the mark 39 and other components, such as the first contact member 23 when the first press-fit member 21 is tilted. Furthermore, the degree of tilt of the mark 39 during installation can be visually determined, allowing for more appropriate installation of the pillar material 12.

The compression force is adjusted using the compression force adjustment plates 29a and 29b described above. The following arrangements for the compression force adjustment plates 29a and 29b are possible. Figure 32 is a cross-sectional view of a case in which one compression force adjustment plate 29a is placed on the mounting surface 79 in a pattern different from that shown in Figure 23. Figure 32 corresponds to the cross section shown in Figure 23.

32, the compression force adjusting plate 29a is disposed so that the mounting surface 79 and the second surface 92a of the compression force adjusting plate 29a face each other. In this case, the compression force adjusting protrusions 93a, 94a, 95a are disposed in the opposite direction to the second pad portion 27 in the Z direction compared to the case shown in FIG. 23. In this way, the height in the Z direction from the second pad portion 27 to the compression force adjusting plate 29a can be changed to a height _H4 that is different from the heights _H1 , _H2 , and _H3 .

Furthermore, Figure 33 is a cross-sectional view showing two compression force adjustment plates 29a, 29b placed on the mounting surface 79 in a pattern different from that shown in Figure 25. Figure 33 corresponds to the cross section shown in Figure 25.

32, with reference also to Figure 33, the compression force adjusting plate 29b is arranged so that the first surface 91a of the compression force adjusting plate 29a faces the first surface 91b of the compression force adjusting plate 29b. In this case, the compression force adjusting protrusions 93a, 94a, and 95a are arranged in contact with the compression force adjusting protrusions 93b, 94b, and 95b, respectively. This allows the height in the Z direction from the second pad portion 27 to the compression force adjusting plate 29b to be changed to height _H5 , which is different from each of the heights _H1 , _H2 , _H3 , and _H4 .

In other words, by using the two compression force adjustment plates 29a, 29b and the second press-fit member 26 configured as described above, a total of five height adjustment patterns, i.e., five levels of compression force adjustment, are possible. In particular, if an error occurs when cutting the pillar material 12 longitudinally, the height can be adjusted to compensate for this error by using and combining the compression force adjustment plates 29a, 29b described above, making it easy to achieve an appropriate compression force that just barely allows the mark 39 to be seen. In other words, even without strict control when cutting the pillar material 12, the compression force adjustment plates 29a, 29b described above can be used to support the pillar material 12 with an appropriate compression force. Of course, depending on the length of the cut pillar material 12, one compression force adjustment plate 29a, 29b may be used, or none of the compression force adjustment plates 29a, 29b may be used at all. Furthermore, three or more compression force adjustment plates 29a, 29b may be used.

In this embodiment, the retaining portion 38 includes protrusions 45a, 45b provided on the first press-fitting member 21. The protrusions 45a, 45b are solid cylindrical and protrude in a direction perpendicular to the direction in which the first press-fitting member 21 and the first contact member 23 are separated. The retaining portion 38 includes guide ribs 61a, 61b provided on the first contact member 23 that receive the protrusions 45a, 45b and restrict their movement. Therefore, the protrusions 45a, 45b included in the retaining portion 38 and provided on the first press-fitting member 21, and the guide ribs 61a, 61b included in the retaining portion 38 and provided on the first contact member 23, can rotatably hold the first press-fitting member 21 so as to more appropriately tilt the first press-fitting member 21. This allows the pillar 12 to be installed more appropriately.

In this embodiment, the protrusion 45a includes a first tip region 47a located on the first contact member 23 side in the direction in which the first press-fit member 21 and the first contact member 23 separate. The first tip region 47a is an inclined surface that slopes so that the amount of protrusion of the protrusion 45a increases from the side closer to the first contact member 23 to the side farther from it. Therefore, the first tip region 47a can be used to more smoothly engage the protrusion 45a with the guide rib 61a.

In this embodiment, the retaining portion 38 includes multiple protrusions 45a, 45b. The retaining portion 38 also includes multiple guide ribs 61a, 61b that receive the multiple protrusions 45a, 45b. This allows the first press-fit member 21, into which the pillar material 12 is press-fitted, to be tilted more stably relative to the first direction. This allows for more reliable installation in the desired position while reducing the risk of damaging the wall surface during installation.

In this embodiment, the compression springs 22a and 22b, which are elastic members, have a spring constant of 1 N/mm or more and 5 N/mm or less. Therefore, the column can be supported while applying tension with an appropriate compressive force between the wall surfaces. In this case, it is possible to prevent the column from being pressed hard against the ceiling wall surface 17 or the floor wall surface 19 with an excessively strong compressive force, which would be caused by a spring constant that is too large. Furthermore, if the spring constant is too small, it is possible to prevent the column 12 from losing support and collapsing, for example, when an impact is applied to the column 12 from the horizontal direction. It is more preferable to use compression springs 22a and 22b with a spring constant of 3 N/mm or more and 4 N/mm or less, from the perspective of maintaining an appropriate compressive force while reducing the user's effort during installation.

(Other embodiments)
In the above embodiment, the cover and the first pad are separate members and the first pad is attached to the cover, but this is not limiting, and the cover and the first pad may be integrally formed. Similarly, the second press-fit member and the second pad may be integrally formed.

In addition, in the above embodiment, the column support supports the column vertically and straight between the ceiling and floor. However, this is not limited to this. The column support may also support the column horizontally and straight between horizontally opposing wall surfaces. In other words, the first wall surface and the second wall surface may be opposing side wall surfaces of a room or space. Furthermore, the column support may support the column in a direction inclined relative to the vertical, that is, between diagonally opposing wall surfaces, straight in the diagonal direction in which the wall surfaces face each other. The angle relative to the vertical may be a small inclination angle of 1 or 2 degrees, or a large inclination angle of 30 degrees.

In the above embodiment, the mark is provided on the first press-fitting member and consists of a linear recess extending in a direction intersecting the direction in which the first press-fitting member and the first contact member are separated.
