Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a handrail mounting bracket used for mounting handrails in a spaced manner on the upper surface of a cape on a wing wall of a staircase or a hallway, or on a vertical wall surface.

BACKGROUND OF THE INVENTION Handrails for stairs, hallways, etc. are generally mounted at intervals via a plurality of handrail mounting brackets fixed at predetermined intervals to the upper surface of a cap of a wing wall or a vertical wall surface. The above-mentioned bracket used for this purpose has a mounting seat at one end of a support rod of a predetermined length for fixing to the wall surface, etc.
Each has a handrail mounting plate on the other end for attaching a handrail.

On the other hand, handrails not only have various cross-sectional shapes such as circular and rectangular, but also have a wide variety of thicknesses, from thin to thick.

By the way, if the distance between the handrail and the wall surface, etc. is too narrow, your hand will come into contact with the wall surface, etc. when grasping the handrail, making it difficult to use.On the other hand, if the distance between the handrail and the wall surface, etc. is too wide, the handrail will protrude beyond the wall surface, etc., and become an obstruction. It is desirable that the spacing be set appropriately, since this may cause the space to become distorted or the appearance to be unsatisfactory.

Problems that the invention aims to solve: However, in the case of conventional handrail mounting brackets, the length of the support rod is constant, so the appropriate length can be adjusted depending on the cross-sectional shape or thickness of the handrail used. Unless a handrail with support rods is used, it is not possible to set an appropriate distance between the handrail and the wall surface, etc. Therefore, it is not only necessary to manufacture and provide a variety of supporting rods with different lengths;
Even when installing the handrail, it was troublesome because one had to be sure to select a support rod with an appropriate length depending on the handrail being used.

This invention was made in view of the above-mentioned problems, and it is possible to appropriately and easily adjust the distance between the handrail and the wall surface, etc., depending on the cross-sectional shape or thickness of the handrail used. It is an object of the present invention to provide a handrail mounting bracket that is comparable in appearance and strength to conventional products.

Means for Solving the ProblemsThe handrail mounting bracket according to this invention has a female threaded cylinder 3 integrally provided on the mounting seat 2, and a male threaded part 4 at the base end 7a of the female threaded cylinder 3. A base 7 of a support rod 6 having a handrail mounting plate 5 at its tip is screwed onto the male threaded portion 4 and inserted so as to be movable forward and backward.

The material of this bracket is generally metal, but it may be made of synthetic resin if necessary.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

The illustrated embodiment is an example of a handrail mounting bracket 1 used for mounting a handrail B on a vertical wall surface A, as shown in FIG. As shown in FIGS. 1 and 2, this bracket 1 includes a disk-shaped mounting seat 2 for fixing to the wall surface A, and a female threaded cylinder 3 having a female thread 3a on the inner peripheral surface protrudingly provided. A base part 7 of a support rod 6 having a circular cross section, bent into a substantially L-shape in side view, has a male thread part 4 corresponding to the female thread 3a at the base end 7a, and a handrail mounting plate 5 at the tip, in the female thread cylinder 3. is screwed onto the male threaded portion 4 and inserted so as to be movable forward and backward.

The tip of the female threaded cylinder 3 is slightly folded inward, and the folded edge 3b closes the space between it and the outer circumferential surface of the base 7 of the support rod 6 almost tightly.
The support rod 6 is supported in the female threaded cylinder 3 without play, and the support rod 6 is prevented from being accidentally pulled out. 8 is a screw hole drilled in the mounting seat 2 and the handrail mounting plate 5.

The bracket 1 has its mounting seat 2 fixed to the wall surface A with screws 9, etc., and then the support rod 6 is rotated to set its protrusion degree appropriately, and the handrail mounting plate 5 is turned upward. A handrail B is fixed to the mounting plate 5, and the handrail B is supported on the wall surface A in a spaced manner.

In addition, in the above embodiment, in order to attach the handrail B to the vertical wall surface A, the support rod 6 was bent into a substantially L-shape when viewed from the side, but this invention is not limited to this. Instead, it is also permissible to make the support rod straight so that it can be attached to the upper surface of the cap of the wing wall of the stairs.

Effects of the invention As described above, the handrail mounting bracket 1 according to this invention has a support rod 6 having a handrail mounting plate 5 at the tip.
The base 7 of the handrail mounting plate 5 is inserted into the female threaded cylinder 3 integrally projecting from the mounting seat 2 so as to be movable forward and backward. The distance between the handrail B and the handrail B attached to the handrail can be freely adjusted. Therefore, handrail B, which is used in advance to set the above-mentioned interval appropriately like the conventional product.
A handrail B that can be used at the installation site without preparing a handrail mounting bracket with a support rod of an appropriate length considering the cross-sectional shape or thickness of the handrail B.
The interval can be variably set as desired. Further, since the male threaded portion 4 provided at the base end 7a of the support rod 6 is screwed into the female threaded tube 3, the distance can be easily adjusted by simply rotating the support rod 6, and the male threaded portion 4 is not exposed from the female threaded tube 3, and in terms of appearance, it can be made comparable to conventional products. Moreover, if the handrail B is fixed to the handrail mounting plates 5, 5... of the plurality of brackets 1, 1... fixed to the wall surface A, etc., each support rod 6, 6... of each bracket 1, 1... Rotation is prevented, and the support rod 6 is also prevented from moving forward and backward, so that the handrail B can be firmly supported on the wall surface A, etc., like the conventional product.
