Description

Application of Article 30, Paragraph 2 of the Patent Act Wake Sangyo Co., Ltd. exhibited a "Support pole fixing device and attachment for items handling fixed supports" at the "58th JAPAN DIY HOMECENTER SHOW 2022" held at the Makuhari Messe International Exhibition Hall from August 25th to 27th, 2022.

This invention relates to a pole fixing device and an attachment for an item that handles a fixed pole, which reduces the number of parts, simplifies the structure, and reduces weight, and which firmly fixes the pole by pressing a ceiling pressure plate against the ceiling surface, allowing the fixed pole to be handled and various everyday items to be easily attached.

For example, a support post fixing device that fixes both ends of a support post by abutting them against the ceiling and floor surfaces may include a receiving member that can abut against the ceiling surface at the upper end of the support post, an adjustment member that can abut against the floor surface at the lower end of the support post, the receiving member having a ceiling abutment plate that can be attached to the ceiling surface, a shaft that protrudes downward from the underside of the ceiling abutment plate, a stop plate fixed to the lower end of the shaft, and the stop plate positioned so that it can engage with the inner surface of the upper end of the support post, and a locking piece with a roughly inverted U-shaped cross section positioned at the bottom of the shaft, which is positioned so that it can engage with the inner surface of the upper part of the support post, and the locking piece A coil spring is attached to the shaft above the locking piece, and the elasticity of the coil spring urges the locking piece downward. The adjustment member has a base that can be attached to the floor surface, a bolt is installed on the base, a nut is screwed onto the bolt, and the backing plate directly above it and the locking piece with a roughly U-shaped cross section are positioned so that they can be supported. By screwing the nut, the backing plate and support of the adjustment member are raised, compressing the coil spring, and the elasticity presses the ceiling contact plate against the ceiling surface, while at the same time pressing the base against the floor surface (see, for example, Patent Document 1).

However, this support pillar fixing device has a large number of parts and a complex configuration, making it difficult to manufacture. Furthermore, it is difficult to position the ceiling backing plate and base on a vertical line, which can lead to the support pillar easily falling over if the position is misaligned.

To solve this problem, there is a column structure that has an upper support that houses the upper end of the column and a lower support that houses the lower end of the column, each of which has a recessed hole to accommodate the upper or lower end of the column. A spring is placed in the bottom of the upper recessed hole, and the width of each recessed hole in the direction away from the indoor wall is approximately 10% wider than the width of the column in the direction away from the indoor wall, positioning the column at an angle. In the event of a rotational force acting on the column that could cause it to fall over due to an earthquake or other event, the column can be prevented from falling and can be more firmly fixed than if it were fixed upright (see, for example, Patent Document 2).

However, this type of column structure has the problem that it is not possible to adequately prevent the columns from falling over when subjected to shaking or impacts such as those caused by an earthquake, and it is difficult to adjust the reaction forces received from the floor and ceiling.

To solve this problem, a column fixing device is provided that has a ceiling presser that is pressed against the ceiling, a column presser that is pressed against a temporary column, and a link mechanism that is arranged between the ceiling presser and the column presser and has a link that widens or narrows the gap between the ceiling presser and the column presser in response to the moment applied to the link. It also has an elastic body that is connected to the link and generates an elastic force in response to the magnitude of the deformation when elastically deformed, and an elastic deformation setting unit that sets the magnitude of the elastic deformation of the elastic body so that an elastic force is generated in the direction in which the moment is applied to the link, and the elastic body generates an elastic force in response to expansion and contraction. There is a column fixing device in which the elastic deformation setting unit has an elastic body connecting member that is connected to the elastic body together with the link, and a member holding unit that holds the elastic body connecting member so that the connection point with the elastic body can be set to one of multiple positions along the direction in which a moment is applied to the link. The member holding unit is positioned to extend in the direction in which a moment is applied to the link, and has a male screw that screws into the female screw of the elastic body connecting member, and a male screw support unit that supports the male screw so that it can rotate while maintaining a fixed position, and adjusts the reaction force received from the floor and ceiling in accordance with the rotation of the male screw (see, for example, Patent Document 3).

However, this pillar fixing device has a large number of parts and a complex configuration, making it difficult to manufacture. Furthermore, because the surface area of the ceiling presser is small, the contact force of the ceiling presser against the ceiling surface is weak, making it difficult to firmly fix the pillar.

The following describes the illustrated embodiment of the present invention. In Figures 1 to 6, reference numeral 1 denotes a support pillar installed vertically between floor surface 2 and ceiling surface 3. In this embodiment, support pillar 1 is made of a wooden timber with a horizontally elongated rectangular cross section (38 mm x 89 mm). A box-shaped pillar holder 4 is disposed at the lower end of support pillar 1, and a ceiling presser 5 is disposed at the upper end of support pillar 1.

The column holder 4 is composed of a flat metal base plate 6 that can be installed on the floor surface 2, and a horizontally elongated rectangular metal box-shaped column holder frame 7 that is connected to the base plate 6 by caulking or welding.
The column holding frame 7 is formed in a box shape that can accommodate the lower end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, so that it can accommodate errors in the processing dimensions of the column 1 and subsequent expansion, contraction, warping, and twisting.

A pair of large dial knobs 8, 8 are rotatably attached to one side of the column holding frame 7, and the end of the inner screw shaft 9 can be pressed against the side of the lower end of the column 1 to fix the lower end of the column 1.
The ceiling pressing body 5 is composed of a metal box-shaped column mounting frame 10 and a metal, generally plate-shaped ceiling pressing plate 11 that can be pressed against the ceiling surface 3. A pantograph mechanism 12 is disposed between these, and the ceiling pressing plate 11 can be raised and lowered by rotating a dial knob 13 on the side of the pantograph mechanism 12.

The pillar mounting frame 10 is formed in a box shape that can accommodate the upper end of the pillar 1, and its shape dimensions are formed to be larger than the cross-sectional shape of the pillar 1, similar to the pillar holding frame 7, so that it can accommodate errors in the processing dimensions of the pillar 1 and subsequent expansion, contraction, warping, and twisting.
The ceiling pressing plate 11 is formed in a horizontally elongated rectangular shape, and its shape is formed to be larger than the cross-sectional area of the pillar mounting frame 10, with its length and width dimensions increased by approximately 10% outside of the cross-sectional area, and its length and width dimensions increased by approximately 13 to 15% compared to conventional similar ceiling pressing plates.

A pair of horizontally elongated rectangular holes 14 are formed in the middle of the ceiling pressing plate 11. These holes 14 function as material slits, reducing the weight of the ceiling pressing plate 11 by an amount equivalent to the area of the holes 14, 14, and reducing the contact or pressing area of the ceiling pressing plate 11 against the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, thereby increasing the reaction force or stress on the ceiling surface 3.

The pantograph mechanism 12 has a pair of first links 15 and second links 16 arranged diagonally so as to be able to cross each other, and the upper and lower ends of the links 15 and 16 are rotatably connected via pins 17 to 20 .
Of these, pin 17 is hung at a fixed position between the side surfaces of the pillar mounting frame 10, pin 18 is formed with a large diameter and has small diameter sections 18a at both ends slidably disposed in elongated guide grooves 21, 21 formed on the side surfaces of the pillar mounting frame 10, pin 19 is hung at a fixed position between bent pieces 22, 22 which are bent downward at the outer opening edges of the long holes 14, 14, and pin 20 is slidably disposed in elongated guide grooves 23, 23 formed in the other bent piece 22, 22. In the figures, reference numeral 24 denotes a pivot pin which rotatably connects the intersection of the first and second links 15, 16.

Long, narrow slots 25, 25 are formed in the middle of both horizontally long sides of the pillar mounting frame 10, and the upper opening edges thereof are bent inward so that the upper end of the pillar 1 can abut against the bent edges 26, 26.
A pair of large dial knobs 27, 27 are rotatably attached to one side of the pillar mounting frame 10, and the ends of the inner screw shafts 28 thereof are pressed against the side of the upper end of the pillar 1, thereby making it possible to fix the upper end of the pillar 1.

A jack screw 29 coaxial with the dial knob 13 is arranged inside the pillar mounting frame 10, and the jack screw 29 is screwed in so as to intersect with the large diameter pin 18, and its threaded shaft is extended and screwed into a fixing nut 30.
Then, the dial knob 13 is rotated, and the jack screw 29 is simultaneously rotated and screwed into the pin 18. The pin 18 is pulled to the upper right in FIG. 1 in response to the rotational displacement of the jack screw 29, and its small diameter portion 18a moves along the guide grooves 21, 21, allowing the first and second links 15, 16 to be raised or lowered.
That is, the first and second links 15 and 16 can be tilted and displaced by rotating the dial knob 13 to the right or left.

In this case, in the embodiment of FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15, 16 are tilted. However, if an upright displacement is desired instead of a tilted displacement, the pin 18 can be configured to be capable of following the rotational displacement of the dial knob 13, and the pin 18 can be moved to the left in FIG. 1 along the guide grooves 21, 21.
In addition, reference numeral 31 in the figure denotes a rubber plate glued onto the ceiling pressing plate 11, which is made up of separate parts that are glued together to prevent marks from being pressed against the ceiling surface 3 and to increase the friction of the ceiling pressing plate 11, allowing it to be pressed firmly and reliably against the ceiling surface 3.

The pillar fixing device constructed in this way requires the pillar holder 4, the ceiling presser 5, and the pillar 1, all of which must be manufactured. Of these, a predetermined piece of wood is selected for the pillar 1, and it is cut to a predetermined length and a predetermined cross-sectional shape according to the distance between the floor surface 2 and the ceiling surface 3.
The column holder 4 is composed of a flat metal base plate 6 that can be installed on the floor surface 2, and a horizontally elongated rectangular metal box-shaped column holder frame 7 that is connected to the base plate 6 by caulking or welding.

The column holding frame 7 is formed into a box shape made of steel plate that can accommodate the lower end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, so that it can accommodate errors in the processing dimensions of the column 1 and subsequent expansion, contraction, warping, and twisting.
A pair of large dial knobs 8, 8 are rotatably attached to one side of the column holding frame 7, and the ends of the inner screw shafts 9 are pressed against the side of the lower end of the column 1, making it possible to fix the lower end of the column 1.

The ceiling presser 5 is composed of a metal box-shaped column mounting frame 10 and a metal, roughly plate-shaped ceiling presser plate 11 that can be pressed against the ceiling surface 3. A pantograph mechanism 12 is placed between these two, and the ceiling presser plate 11 can be raised and lowered by rotating a dial knob 13 on the side of the pantograph mechanism 12.

The column mounting frame 10 is formed in a box shape capable of accommodating the upper end of the column 1, and its shape dimensions are formed larger than the cross-sectional shape of the column 1, similar to the column holding frame 7, so that it can accommodate errors in the processed dimensions of the column 1 and subsequent expansion/contraction, warping and twisting.
The ceiling pressing plate 11 is formed in a horizontally long rectangle, and its shape dimensions are formed larger than the cross-sectional area of the column mounting frame 10, and the vertical and horizontal dimensions are formed to be increased by about 10% outside the cross-sectional area, so that the vertical and horizontal dimensions are increased by about 13 to 15% compared to a conventional similar ceiling pressing plate.

A pair of horizontally elongated rectangular holes 14 are formed in the middle of the ceiling pressing plate 11, and these holes 14 function as material slits, reducing the weight of the ceiling pressing plate 11 by an amount equivalent to the area of the holes 14, 14. This also reduces the contact or pressing area of the ceiling pressing plate 11 with the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, thereby increasing the reaction force or stress on the ceiling surface 3.

Each pair of first and second links 15 and 16 of the pantograph mechanism 12 is disposed obliquely so as to be able to cross each other.
Of these, pin 17 is hung at a fixed position between the side surfaces of the pillar mounting frame 10, and pin 18 is formed with a large diameter, with small diameter portions 18a at both ends thereof being slidably positioned in elongated guide grooves 21, 21 formed on the side surfaces of the pillar mounting frame 10.

The pin 19 is placed in a fixed position between two downwardly bent pieces 22, 22 on the outer opening edge of the long holes 14, 14, and the pin 20 is slidably positioned in a narrow guide groove 23, 23 formed in the other bent piece 22, 22. The intersection of the first and second links 15, 16 is then pivotally mounted by a pivot pin 24.

Long, narrow slots 25, 25 are formed in the middle of both horizontally long sides of the pillar mounting frame 10, and the upper opening edges thereof are bent inward so that the upper end of the pillar 1 can abut against the bent edges 26, 26.
A pair of large dial knobs 27, 27 are rotatably attached to the lower part of one side of the pillar mounting frame 10, and the end of the inner screw shaft 28 is pressed against the side of the upper end of the pillar 1, making it possible to fix the upper end of the pillar 1.

A jack screw 29 coaxial with the dial knob 13 is arranged inside the column mounting frame 10, and the jack screw 29 is rotatably supported at a fixed position. The jack screw 29 is screwed in so as to intersect with the large-diameter pin 18, and its screw shaft is extended and screwed into a fixing nut 30.
Then, the dial knob 13 is rotated, and the jack screw 29 is simultaneously rotated and screwed into the pin 18. The pin 18 is pulled to the right in FIG. 1 in response to the rotational displacement of the jack screw 29, and its small diameter portion 18a moves along the guide grooves 21, 21, allowing the first and second links 15, 16 to be raised or lowered.
That is, the dial knob 13 is rotated to the right or left, so that the first and second links 15, 16 can be tilted and displaced.

In this case, in the embodiment of FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15, 16 are tilted, but if an upright displacement is required instead of a tilting displacement, the pin 18 is caused to follow the rotational displacement of the dial knob 13, and the pin 18 is moved to the left in FIG. 1 along the guide grooves 21, 21.
A rubber plate 31 is adhered onto the ceiling pressing plate 11, and each part of the rubber plate 31 is divided and adhered to prevent the occurrence of pressing marks on the ceiling surface 3, and also increases the friction of the ceiling pressing plate 11, making it possible to press the plate firmly and surely against the ceiling surface 3.

In this way, the ceiling pressure plate 11 is formed into a horizontally elongated rectangle, with its dimensions larger than the cross-sectional area of the column mounting frame 10, and its length and width are increased by approximately 10% outside of that cross-sectional area, resulting in a larger size with length and width dimensions approximately 13-15% larger than conventional similar ceiling pressure plates.

A pair of horizontally elongated rectangular holes 14 are formed in the middle of the ceiling pressing plate 11, and the holes 14 function as so-called material stealers, reducing the weight of the ceiling pressing plate 11 by an amount equivalent to the area of the holes 14, 14, and reducing the contact area or pressing area of the ceiling pressing plate 11 with the ceiling surface 3 by an amount equivalent to the area of the holes 14, 14, thereby making it possible to increase the reaction force or stress on the ceiling surface 3.
In addition, the divided components of the rubber plate 31 are adhered to the ceiling pressing body 5, thereby increasing the friction, and since there is no need to incorporate a spring into the pillar mounting frame 10 as in the past, the structure is simpler and can be easily manufactured.

When the column holder 4, ceiling presser 5, and column 1 thus manufactured are used to fix the column 1 vertically between the floor surface 2 and the ceiling surface 3, for example, a plumb line is hung from a predetermined position on the ceiling surface 3 where the column 1 is fixed, and the column holder 4 is placed on the corresponding floor surface 2.
Then, the lower end of the support 1 is placed in the support frame 7 of the support body 4, and the dial knobs 8, 8 are rotated to press the end of the screw shaft 9 against the side of the lower end of the support 1, thereby fixing the lower end of the support 1 in place.

In this case, the dial knobs 8, 8 are large, making them easy to rotate and securing the support 1 simple. Furthermore, the box-shaped dimensions of the support frame 7 are larger than the cross-sectional shape of the support 1, allowing for quick adjustment to errors in the processing dimensions of the wooden support 1, as well as any subsequent expansion, contraction, warping, or twisting.

Next, the support column 1 is held upright in the column holding frame 7, and the box-shaped column mounting frame 10 is fitted onto the upper end of the support column 1, and the upper end of the frame 10 is held in contact with the bent pieces 26, 26.
Thereafter, the dial knobs 27, 27 are rotated to press the ends of the threaded shafts 28, 28 against the side of the upper end of the support column 1, thereby fixing the upper end of the support column 1. In this state, the support column 1 is temporarily held in an upright position between the column holding frame 7 and the column mounting frame 10.

In addition, the dial knobs 27, 27 are large, allowing for easy rotation and simple fixing of the support 1. Furthermore, the box-shaped dimensions of the support frame 10 are larger than the cross-sectional shape of the support 1, allowing for quick adjustment to errors in the processing dimensions of the wooden support 1, as well as any subsequent expansion, contraction, warping, or twisting.

Under these circumstances, the dial knob 13 is rotated to start the pantograph mechanism 12 and raise or lower the ceiling pressing plate 11. For example, the dial knob 13 is rotated to the right, which moves the jack screw 29 in unison, pulling the pin 18 to the right in FIG. 1 in response to the rotational displacement of the jack screw 29, moving the small diameter portion 18a along the guide grooves 21, 21 and raising or lowering the first and second links 15, 16.
In the embodiment shown in FIG. 1, when the dial knob 13 is rotated to the right, the first and second links 15 and 16 are tilted and displaced.

In this case, if you want to make an upright displacement instead of a tilting displacement, the pin 18 is made to follow the rotational displacement of the dial knob 13, and the pin 18 is moved along the guide grooves 21, 21 to the left in Figure 1.

When the first and second links 15, 16 are displaced upright in this way and the ceiling push plate 11 is pressed against the ceiling surface 3, the contact surface pressure gradually increases and acts as a reaction force on the ceiling surface 3. As a result, the upper end of the support column 1 is fixed to the ceiling surface 3, and the support column 1 is fixed in an upright position between the ceiling surface 3 and the floor surface 2.

In this case, the ceiling pressing plate 11 is formed larger than the cross-sectional area of the pillar mounting frame 10, and is formed on the outside of the pillar mounting frame 10 with its length and width dimensions increased by about 10%, and is formed larger with its length and width dimensions increased by about 13 to 15% compared to conventional ceiling pressing plates of the same type, so the contact area or pressing area with the ceiling surface 3 is increased, and the reaction force is increased to firmly fix the pillar 1.
Furthermore, the ceiling pressing plate 11 has long holes 14, 14 formed in the middle, which reduce the contact area or pressing area with the ceiling surface 3 by an amount equivalent to the area of these holes, thereby increasing the reaction force or stress against the ceiling surface 3 and firmly fixing the support 1.

The pole 1 thus erected and fixed can be handled, and a hook holder 32 attached to the desired position, and then processed or welded to it as appropriate, so that various daily necessities can be easily hung and used. That is, Figures 7 to 23 show a second embodiment of the present invention, and the same reference numerals are used for components corresponding to those of the above-mentioned embodiment.
Of these, Figures 7 to 9 show a hook holder 32 that is attached to an upright fixed support 1, and a pair of hook arms 37, 37 that are attached to both sides of the hook holder 32 to clamp and hold the support 1, and these are used in each of the specific examples in Figures 10 to 23.

The hook holder 32 comprises a holder body 33 that is attached to the periphery of the support pole 1 at an appropriate position, and hook fittings 34 that are attached to both sides of the body 33. The holder body 33 is made from steel plate formed into a horizontally elongated rectangle or square, with the top and bottom edges bent inward to form hook rails 35, 36 with a roughly U-shaped cross section, and both ends of the hook fittings 34, 34 are slidably inserted into the hook rails 35, 36.

The hook fittings 34 are made of steel wire of an appropriate diameter, in this embodiment a steel wire with a diameter of 8 mm, and have hook arms 37, 37 bent and formed at the upper and lower ends thereof in a U-shape when viewed from above. These pair of hook arms 37, 37 are positioned on either side of the support 1, and the distance between them can be adjusted so that both sides of the support 1 can be clamped and held.
A nut 38 is fixed to the front center of the holder body 33 , and a large knob 39 and a threaded shaft 40 coaxial with the nut 38 are screwed into the nut 38 , so that the end of the shaft can be pressed against the circumferential surface of the support 1 .
In this case, it is desirable to fix a nut (not shown) onto the back surface of the holder body 33, into which the screw shaft 40 can be screwed, place a large-diameter circular pressing plate on the outside of the nut, fix another nut (not shown) onto which the screw shaft 40 can be screwed onto one side of the pressing plate, and arrange the pressing plate so that it can be pressed against the circumferential surface of the support 1, thereby preventing the formation of pressing marks on the support 1 by the screw shaft 40.
