Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail bracket for supporting a handrail disposed on a wall surface or the like.

Conventionally, this type of handrail bracket has been made up of a collar-shaped mounting base that is fixed to a wall surface, and a support part that integrally projects from the surface side of this mounting base and supports the handrail body. When installing such handrail brackets, the usual method is to embed the required number of locking devices such as plugs with threaded parts in advance at predetermined locations on the wall surface to be installed, and to protrude from approximately the center of the mounting base. The handrail bracket was fixed to the wall by inserting a mounting bolt into a bolt through hole and threading the mounting bolt into a locking tool embedded in the wall.

However, if the wall is made of concrete, for example,
When forming a wall, it is sometimes difficult to avoid some unevenness on the wall surface, and in that case, it becomes necessary to adjust the distance between the handrail and the wall surface and install the handrail. The brackets could not be adjusted to the wall surface, making it impossible to attach the handrail to the wall surface.

In order to eliminate this drawback, there are handrail brackets that can adjust the distance from the wall surface, but they have a complicated structure, the operation of attaching the handrail bracket to the wall surface is troublesome, and it is not reliable. Nakatsuta.

Therefore, in view of the above points, the present invention provides a flange-shaped mounting board that abuts against a wall surface and has an insertion hole and a fitting opening formed approximately in the center thereof, and a fitting opening that has a distal end formed in the mounting board. A cylindrical adjustment ring that is fitted into the ring and has a female thread on its inner circumferential surface, and a male thread on the outer circumferential surface that contacts the female thread of the adjustment ring, A support rod having an adjustment part having a through hole that communicates with the insertion hole of the mounting board and a support part that supports the handrail body, and a mounting that is inserted into the through hole of the adjustment part that communicates with the insertion hole of the mounting board. The object of the present invention is to provide a handrail bracket that has a simple structure and allows for easy and reliable adjustment of the distance between the wall surface and the handrail. .

An embodiment of the present invention will be described below with reference to the accompanying drawings. Figures 1 and 2 show a handrail bracket of the present invention, which is in contact with a wall surface and inserted approximately in the center. A flange-shaped mounting board A having an opening and a fitting hole formed therein, and a cylindrical shape whose tip part is fitted into the fitting opening formed in this mounting board and has a female threaded part screwed onto the inner circumferential surface. an adjustment ring B, a male threaded part is threaded on the outer peripheral surface in contact with the female threaded part of this adjustment ring, and an adjustment part and a handrail body having a through hole communicating with the insertion hole of the mounting board approximately in the center thereof. A support rod C equipped with a supporting part for supporting
The main part is constituted by a mounting tool D that is inserted into a through hole of the adjustment section that communicates with the insertion hole of the mounting board.

To explain the structure of the above handrail bracket in more detail, 1 in the figure is a concrete wall, and a flange-shaped mounting board A is in contact with the wall surface 1a of the wall 1.
has a substantially rectangular shape, its back surface 2 contacts the wall surface 1a, and its opposite surface 3 becomes thicker from the tip 4 toward the center, into which the adjustment ring B is fitted. While the fitting opening 5 is formed,
An insertion hole 6 for a mounting bolt, which is the mounting tool D, is bored.

The adjustment ring B that is fitted into the fitting opening 5 of the mounting board A has a cylindrical shape, and its tip 7 fits into the fitting opening 5 of the mounting board A, and the inner peripheral surface has a female thread 8.
is formed.

C is a support part that supports the handrail body 18 with a support rod.
C', and an adjustment part C'' formed integrally with this support part C' and fitted into the adjustment ring B.The adjustment part C'' of the support rod C has a cylindrical shape. A male thread 9 is threaded over almost the entire length of the outer peripheral surface of the adjustment ring B. By screwing this male thread 9 into a female thread 8 formed on the inner peripheral surface of the adjustment ring B, the adjustment part C'' is adjusted. It is screwed into the adjustment ring B. A through hole 10 is formed in the center of the adjustment ring B.
This bolt through hole 10 communicates with the insertion hole 6 of the mounting board A when the adjustment ring B into which the adjustment part C'' is fitted is fitted into the fitting opening 5 of the mounting board A, and the mounting bolt D connects with this through hole 10. It can be inserted through the insertion hole 6 and locked to the wall surface 1a of the handrail bracket as described later.

The support part C' of the support rod C that is integrally formed with this adjustment part C'' and supports the handrail body 18 is the adjustment part
It is formed into two parts and protrudes upward from the tip of the supporting part C''.
As shown in FIG. 3, a support piece 12 having a T-shaped cross section is formed and extends substantially parallel to the wall surface 1a. An insertion groove 13 is formed in this support piece 12,
A set screw mounting hole 14 is bored above this insertion groove 13. A set screw 15 is inserted from below through this insertion groove 13 and screwed into the set screw mounting hole 14.
A substantially rectangular rotation locking piece 17 is screwed onto the set screw 15 and attached to the tip end surface 16 of the support piece 12 at the tip of the set screw 15.
can be rotated left and right around the set screw 15 by rotating the set screw 15.

The handrail main body 18 attached to this support part C' has a U-shaped cross section and includes a guide rail 20 having a groove part 19 on the lower side, and this guide rail 20.
A synthetic resin covering 21 that is attached to cover the
This covering body 21 is fitted into notches 22 formed on both sides of the guide rail 20. Further, a locking groove 23 is formed above the groove 19 of the guide rail 20 in communication with the groove 19 in a direction perpendicular to the groove 19.

In order to fit the handrail main body 18 to the support part C', as shown in FIGS. Cover the guide rail 20 from above so that the groove 19 of the guide rail 20 fits into the support piece 12 formed in the guide rail 20. In this case, as shown in FIG. 3, the rotation locking piece 17 is positioned in the same direction as the longitudinal direction of the distal end surface 16 of the support piece 12 (ie, in the direction of the solid line), and the guide rail 20 is placed over the support piece 12. As a result, the rotation locking piece 17 fits within the locking groove 23 of the guide rail 20. Next, when a tool such as a screwdriver is inserted from below into the insertion groove 13 formed in the support piece 12 and the set screw 15 is rotated, the rotation locking piece 17 is inserted into the third locking groove 23. It rotates as indicated by the dotted line in the figure and is perpendicular to the longitudinal direction of the tip surface 16 of the support piece 12 .
As a result, as shown in FIG. 2, the guide rail 20 is prevented from moving upward by the rotation locking piece 14, and the handrail body 18 is securely fitted to the support portion C'.

The above mounting board A, adjustment ring B, support rod C,
To attach the handrail bracket consisting of the fixture D to the wall surface 1a, first attach the adjustment ring to the external thread 9 formed on the outer periphery of the adjustment section C'' which is integrally formed with the support section C' of the support rod C. The adjustment part C'' is fitted into the adjustment ring B by screwing the female screw 8 screwed onto the inner periphery of the adjustment ring B. When the tip 7 of the adjustment ring B into which the adjustment part C'' is fitted is fitted into the fitting hole 5 of the mounting board A, the insertion hole 6 of the mounting board A and the through hole 10 of the adjustment part B communicate with each other. Then, the back surface 2 of the mounting board A is brought into contact with the wall surface 1a, and the mounting bolt, which is the mounting tool D, is inserted into the through hole 10. 11 is the head of this mounting bolt. The handrail bracket is temporarily fixed to the wall surface 1a by screwing into a female threaded portion 25 screwed into a locking device such as a plug 24 buried at the location.

Next, the distance adjustment between the wall surface 1a and the handrail body 18 is as follows.
As mentioned above, when the handrail bracket is temporarily fixed to the wall surface 1a with the mounting bolt D and then the adjustment ring B is rotated, the adjustment part C'' of the support rod C is adjusted to the adjustment ring B.
Since it is screw-fitted with the handrail body 18, it can be moved from side to side, and as a result, the support part C' that supports the handrail body 18, which is integrated with the adjustment part C'', moves to arbitrarily adjust the distance between the wall surface 1a and the handrail body 18. Next, firmly tighten the temporarily fastened mounting bolts D to firmly fix the handrail bracket to the wall 1.

Furthermore, the handrail main body is fitted to the supporting portions C' of the required number of handrail brackets fixed to the wall 1 in the manner described above to complete the handrail with the wall.

As described above, according to the present invention, when adjusting the distance between the wall surface and the handrail main body, the mounting board and the adjustment part can be mounted to the wall with a single mounting bolt, so that the mounting board and the mounting board can be attached to the wall as in the conventional case. Also, compared to the case where separate mounting bolts were used for the mounting board and the adjustment section, the handrail bracket can be easily mounted to the wall.

In addition, since the adjustment part of the support rod is screwed into the adjustment ring, there is an advantage that the distance between the wall surface and the handrail body can be reliably adjusted with a simple structure by simply rotating the adjustment ring. .
