Description

  The present invention relates to a handrail bracket.

  As a handrail bracket capable of adjusting a distance from a handrail mounting base such as a handrail support or a wall surface, the one described in Patent Document 1 is known.

  In this conventional example, the handrail bracket is formed by connecting a bracket main body 21b to a bracket base 30 fixed to a handrail support column so as to be slidable in the front-rear direction.

Japanese Patent No. 397789

  However, in the above-described conventional example, the slide adjustable dimension of the bracket body is determined by the depth of the coupling piece insertion portion 31 of the bracket base, and in order to increase the adjustment dimension, it is necessary to deepen the coupling piece insertion portion. .

  On the other hand, as shown in FIG. 11 of Patent Document 1, the support portion of the handrail headwood is disposed at a position further protruding forward from the tip edge of the connecting piece insertion portion. If the projecting dimension of the bracket body 2 becomes large and the bracket body 2 is not formed in a complicated shape, there is a problem that the distance from the support column 1 before adjustment becomes excessive.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a handrail bracket with a simple structure and a large adjustment allowance from the mounting base 1, and a handrail using the handrail bracket.

According to the present invention, the object is
A bracket body 2 fixed to a mounting base 1 such as a wall surface or a handrail post;
A head support 4 that is connected to the bracket main body 2 so as to be horizontally rotatable at a position spaced from the fixing portion of the bracket main body 2 to the mounting base 1, and supports the handrail head 3 at a position appropriately spaced from the center of rotation. This is achieved by providing a handrail bracket having a spacing adjusting member 5 with

  The handrail bracket is formed by connecting a distance adjusting member 5 to a bracket body 2 fixed to a mounting base 1 such as a wall surface or a column. The interval adjusting member 5 is rotatably connected to the bracket body 2 at a position spaced apart from the fixing portion of the bracket body 2 to the mounting base 1 by a predetermined interval, and supports the headboard formed on the interval adjusting member 5 by the rotating operation. The distance from the mounting base 1 of the part 4 can be freely adjusted.

  Therefore, in the present invention, adjustment from the initial setting position toward the approaching side can be performed by rotating the rotation adjusting member, and the adjustment allowance can be increased.

As another aspect of the present invention for achieving the above object,
The bracket body 2 is provided with a head support 6 that supports the handrail head 3 at a predetermined distance from the mounting base 1.
The spacing adjusting member 5 can be configured as a handrail bracket that externally fits the head support 6 of the bracket body 2 and is connected to be rotatable and detachable around the external fitting position.

  In the present invention in which the distance adjusting member 5 is attachable / detachable to the bracket body 2 and the bracket body 2 is provided with the head support 6, the distance from the mounting base 1 of the handrail head 3 is a preset value. In some cases, the handrail head 3 can be supported using only the bracket body 2, and when the installation distance from the mounting base 1 of the handrail head 3 increases or decreases from the set value, the distance between the bracket body 2 is adjusted. The member 5 is mounted, and the handrail head 3 can be supported by the head support 4 provided on the distance adjusting member 5.

  Therefore, in the present invention, when it is not necessary to adjust the installation position of the handrail head 3 with respect to the mounting base 1, the handrail head 3 can be supported using only the bracket body 2, so that the cost can be reduced. become.

  Further, since the head support 6 of the bracket main body 2 that is no longer required when the interval adjusting member 5 is mounted is covered with the interval adjusting member 5, the aesthetic appearance can be enhanced.

Furthermore, as another aspect of the present invention for achieving the above object,
The spacing adjusting member 5 may constitute a handrail bracket that is supported by a coping support surface 7 formed on the coping support portion 6 of the bracket body 2 and that is rotatably connected to a fixing position by a fixing element 8. it can.

  The interval adjusting member 5 can be connected by any appropriate means, but when supported and connected by the coping support surface 7 as in the present invention, the interval adjusting member 5 and the handrail coping fixed to the interval adjusting member 5 are used. Since the load bearing member 3 is not required to be provided on the bracket body 2, the structure is simplified.

As another aspect of the present invention for achieving the above object,
The bracket body 2 can constitute a handrail bracket that can be connected to the mounting base 1 by sandwiching the column-shaped mounting base 1 around the clamping position so that the rotational position can be adjusted.

  When the mounting angle of the bracket body 2 to the mounting base 1 cannot be adjusted, the plane including the fixing point of the bracket body 2 (handrail installation reference surface (S)) and the distance adjustment member 5 by the rotation operation to the distance adjustment member 5 It is possible to adjust the distance from the headboard support portion 4 at the corner, but at the corner portion where the handrail installation reference plane (S) intersects, as shown in FIG. When the installation interval of the handrail headboard 3 with respect to S) is changed, the interval with the other handrail installation reference plane (S) does not match the changed value.

  On the other hand, as shown in FIG. 8B, by allowing the bracket main body 2 to rotate with respect to the mounting base 1 as in the present invention, etc., as shown in FIG. It becomes possible to arrange the handrail headboard 3 at intervals, and even when the handrail installation reference plane (S) intersects at an angle other than 90 ° as shown in FIG. It becomes possible to arrange the handrail headwood 3 in

  Therefore, in the present invention, for example, it is possible to install the handrail headboard 3 with the distance from the two handrail installation reference planes (S) being kept equal even at the exit corner or the entrance corner.

Furthermore, the handrail using the handrail bracket is
A handrail in which a handrail headboard 3 arranged along a handrail installation reference plane (S) intersecting at a predetermined angle in the corner portion is connected via a corner connector 9 arranged in the corner portion,

By adjusting the rotational position of the handrail bracket with respect to the mounting base 1 and the rotational position of the spacing adjusting member 5 with respect to the bracket body 2, the handrail head 3 is arranged at equal intervals with respect to the handrail installation reference plane (S). can do.

The adjustment of the rotational position of the handrail bracket with respect to the mounting base 1 takes into account the case where the mounting base 1 is a wall surface, relative to the bracket body 2 between the fixing member for the mounting base 1 and the member to which the interval adjusting member 5 is connected. Although it is possible to realize by connecting rotatably, when the mounting base 1 is formed in a columnar shape,
The bracket main body 2 has a simple structure if it is formed with a handrail that is fixed to the mounting base 1 so that its rotational position can be adjusted by sandwiching the mounting base 1 from the side.

  According to the present invention, the adjustment allowance from the mounting base can be increased with a simple structure.

  The handrail is formed by arranging two upper and lower handrail heads 3 along a handrail installation reference plane (S) configured by connecting handrail columns as the attachment base 1. As shown in FIG. 2B, each handrail headwood 3 is formed by providing a resin layer 3b around a pipe-shaped core 3a.

  In addition, the two handrail installation reference planes (S) are perpendicular to each other to form corners, and the handrail heads 3 arranged along the respective handrail installation reference planes (S) are connected to the corners. They are connected to each other through the tool 9.

  As shown in FIG. 3, each handrail support column 1 has its lower end embedded and fixed on the installation floor 10, and the corner connector 9 that connects the upper handrail heads 3 is connected to the handrail via the head connector 11. It is fixed to the upper end of the column 1.

  As shown in FIG. 4A, the head connector 11 is fixed by inserting the holding block 11a into the hollow portion of the handrail support column 1, and the steel stopper plate 11b fixed to the lower end of the holding block 11a is handrailed. It is prevented from coming off by being brought into pressure contact with the inner wall surface of the column 1.

  The corner connector 9 is formed by overlapping upper and lower hemispherical portions 9a and 9b obtained by dividing a sphere in the horizontal direction by overlapping the divided planes 9c, passing through the center of the sphere and perpendicular to the divided plane 9c. , 9b is used to connect to the head connector 11 using a bolt 9d. In order to prevent the head of the bolt 9d from being exposed to the outside, the bolt head housing portion 9e of the upper hemisphere portion 9a is closed by the cap 12.

  A spherical bearing concave surface 11c that supports the lower hemisphere portion 9b is formed on the upper surface of the head coupler 11 and has a curvature that matches the curvature of the spherical bottom surface of the lower hemisphere portion 9b. The lower hemisphere portion 9b is horizontally rotated around the bolt 9d with the spherical bottom surface and the bearing concave surface 11c as the sliding contact surface and the upper hemisphere portion 9a as the sliding contact surface while being connected to the head coupling tool 11. be able to.

  Further, the upper and lower hemispherical portions 9a and 9b are connected to the upper end of the handrail headboard 3 with a headboard fitting portion 13a for fixing and fixing the end portion of the handrail headboard 3, and the opposite end portion is provided with a fitting convex portion 13b having a curved surface. The member 13 is connected to the same height position. The upper and lower hemispherical portions 9a and 9b are fitted with fitting convex portions 13b of the cap coupling member 13 and a fitting concave portion 14 whose bottom wall has the same curvature as the fitting convex portion 13b is formed. The connecting member 13 is connected to the upper and lower hemispherical portions 9a and 9b by fitting the fitting convex portion 13b into the fitting concave portion 14 formed in the upper and lower hemispherical portions 9a and 9b and then attaching the bolt 15 to the fitting concave portion 14. It is done by screwing into the bottom wall.

  The bolt insertion hole 13c of the fitting convex portion 13b is formed by a long hole in the vertical direction, and the headboard connecting member 13 connected to the upper and lower hemispherical portions 9a and 9b can be rotated in the vertical direction.

  Therefore, in this embodiment, the headboard connecting member 13, that is, the handrail headboard 3 connected to the headboard connecting member 13, is rotated horizontally around the bolt 9d from the linear posture shown in FIG. The bending postures shown in a), (b) and (c) are changed to correspond to the entrance corner or the exit corner, and further, as shown in FIG. And vertically rotating along the boundary of the fitting recess 14 of the upper and lower hemispherical portions 9a, 9b, can correspond to the inclination of the handrail head 3.

  Furthermore, a corner coupler 9 that couples the lower handrail caps 3 to each other is attached to the handrail support column 1 at the corner portion via a handrail bracket (B).

  As shown in FIG. 6, the handrail bracket (B) is formed by connecting a distance adjusting member 5 to a bracket body 2 attached to the handrail column 1. The bracket main body 2 is attached to the handrail post 1 by sandwiching the handrail post 1 between the semi-cylindrical portion 2a formed at one end of the bracket main body 2 and the semi-cylindrical portion 16a of the cover piece 16. After the locking portion 16b formed at one end is locked to the bracket body 2, it is rotated around the locking position, and the opposite end is fastened to the bracket body 2 by the connecting bolt 17.

  As shown in FIG. 6, the semi-cylindrical portion 16a of the cover piece 16 and the semi-cylindrical portion 2a of the bracket body 2 have appropriate height dimensions, and the gravity of the handrail head 3 is described later. Since the load is applied to a position away from the center, a counterclockwise rotational moment is generated in the bracket body 2 in FIG. As a result, the pressure contact force to the handrail strut 1 at the lower end (point P in FIG. 6A) of the cylindrical portion formed by the bracket main body 2 and the cover piece 16 may increase and inadvertently descend downward. Therefore, it is possible to easily adjust both the rotation posture and the mounting height of the bracket body 2 with respect to the handrail strut 1 while the handrail strut 1 is gently gripped by the bracket body 2 and the cover piece 16.

  The bracket body 2 is provided with a head support 6. The head support 6 is formed in a circular cross section and protrudes upward from the opposite end to the semi-cylindrical part 2a. At the upper end of the head support 6, a concave head support surface 7 formed by a spherical surface is formed.

  On the other hand, the gap adjusting member 5 is formed in an arm shape having a fitting recess 5a fitted on the head support 6 of the bracket body 2 at one end and the head support 4 at the other end.

  In this example, the coping support portion 4 of the interval adjusting member 5 is formed in a concave shape by the same curvature surface as the coping support surface 7 of the bracket body 2 and the same as the lower hemispherical portion 9b of the corner connector 9. A corner connector 9 is connected to the head support 4 using bolts 9d.

  Further, the ceiling surface of the fitting recess 5 a of the gap adjusting member 5 is formed as a convex surface having a slightly smaller curvature than the curvature of the head support surface 7, and the convex surface is supported on the head support surface 7 of the bracket body 2. In this state, the bolt 8 is used to screw onto the head support surface 7.

  In the screwed state, the interval adjusting member 5 can be rotated with respect to the bracket body 2 around the screwing point.

  Therefore, in this example of fixing the corner coupler 9 to the head support 4 of the spacing adjustment member 5, when the spacing adjustment member 5 is rotated from the position shown in FIG. 7A to the position shown in FIG. 7B, The distance from the handrail post 1 can be adjusted from D0 to D1.

  Further, by adjusting the rotation position of the interval adjusting member 5, the head support 4 for fixing the corner connector 9 is moved closer to the handrail column 1 than the rotation center position of the interval adjusting member 5 as shown in FIG. (Distance D2).

  FIG. 8 shows the adjustment of the distance from the handrail installation reference plane (S) when the handrail bracket 3 (B) configured as described above is used to fix the handrail headboard 3 to the corner.

  First, FIG. 8A corresponds to FIG. 1A, and the center of rotation of the interval adjusting member 5 and the interval on the bisector of the crossing angle (90 °) of the handrail installation reference plane (S). The cap support 4 of the adjustment member 5 is disposed.

  When the rotational position of the bracket body 2 with respect to the handrail support column 1 and the rotational position of the interval adjusting member 5 with respect to the bracket body 2 are adjusted from this state as shown in FIG. The distance from the handrail installation reference plane (S) can be made equal to approach the handrail installation reference plane (S) side.

  In FIG. 8C, when only the interval adjusting member 5 is rotated without changing the rotation position of the bracket body 2 with respect to the handrail support column 1, the interval from the two handrail installation reference surfaces (S) is shown. It is explanatory drawing which shows that it cannot be equal.

  Further, FIGS. 8A and 8B show the dimension adjustment at the perpendicular corners, but the rotation position of the bracket body 2 with respect to the handrail column 1 and the rotation position of the spacing adjustment member 5 with respect to the bracket body 2 are shown. When properly adjusted, as shown in FIG. 8 (d), the distance from the two handrail installation reference planes (S) can be made equal even at a corner portion that intersects at an intersection angle other than 90 °.

  As described above, the intermediate portion of the handrail headwood 3 connected to each other by the corner connector 9 at the corner is supported by the intermediate support 18 as shown in FIGS. 1 (a) and 2 (a). The

  As shown in FIG. 9, the intermediate support tool 18 is formed by connecting a pair of holding pieces 18a having a predetermined length with bolts 18b. After the handrail head 3 is held between the holding pieces 18a, the tapping screw 18c is screwed. As a result, the handrail head 3 is fixed.

  As shown in FIG. 9A, the intermediate support 18 that supports the upper handrail headboard 3 uses bolts 18 b that connect the clamping pieces 18 a to the head connector 11 that is connected to the upper end of the handrail column 1. Connected.

  On the other hand, as shown in FIG. 9B, the intermediate support 18 that supports the lower handrail headwood 3 is connected to an intermediate bracket 19 attached to the handrail support column 1 using bolts 18b. The intermediate bracket 19 is attached to the handrail column 1 with the same configuration as that of the bracket body 2 at the corner described above.

  The intermediate support 18 is vertically rotatable around the bolt 18b with respect to the head connector 11 and the intermediate bracket 19, and corresponds to the handrail headwood 3 disposed in an inclined posture.

  Furthermore, as shown to Fig.1 (a), the cap member 20 is mounted | worn with the terminal part of a handrail headboard. The cap member 20 is formed in a cylindrical shape with one end closed, and is connected to the head connector 11 or the intermediate bracket 19 using the bolt 18b in the same manner as the intermediate support 18 described above.

  In the above, the case where the intermediate portion of the handrail headboard 3 is supported by the intermediate support 18 has been shown. However, when the handrail headboard 3 is connected to each other by the above-described corner connector 9, the staircase handrail shown in FIG. In addition, a handrail that bends in the vertical direction can be formed.

  In this case, in order to fix the corner connector 9 of the longitudinally bent portion, the bracket body 2 in which the interval adjusting member 5 is removed from the handrail bracket (B) used in the corner portion is used. As shown in FIG. 10 (b), the bracket body 2 is connected to the coping support portion 46 of the bracket body 2 using bolts.

  Therefore, in this embodiment, since the bracket body 2 used in the corner portion can be used as it is in a portion other than the corner portion, the number of parts can be reduced.

  In the above, the pipe-shaped core 3a of the handrail head 3 is shown as being formed in a cylindrical shape, but in addition to this, as shown in FIG. 12, reinforcing ribs 3c are protruded at a predetermined pitch in the circumferential direction. Things can be used. In this case, the tapping screw 18c for fixing to the corner connector 9 or the like is screwed into a position avoiding the reinforcing rib 3c as shown by a chain line in FIG.
