Description

[Detailed description of the device] [Purpose of the device] "Industrial application field" This device is a handrail installed on a wall surrounding a roof of a building, a handrail of a veranda, a handrail of a staircase, and a handrail of a landing of a staircase. The present invention relates to a mounting structure for a handrail such as an assembly type.

"Conventional technology" Conventionally, many handrails were made of wood and iron, but due to problems with durability and maintainability, it is recommended to use a handrail rod made of extruded aluminum with a handrail. Is starting to happen. An example of applying such a handrail to the rooftop or the veranda is as follows.

For example, in the case of the rooftop as shown in FIG. 6, the waist high wall 2 is attached to the edge of the floor 1.
Is provided, the handrail 3 is fixed to the upper part of the high waist wall 2, and the handrail bar 4 is attached to the handrail 3.

As a conventional example of a structure for attaching the handrail bar 4 to the handrail 3, there is one as shown in FIGS. 7 and 8.

In FIG. 7, an arcuate receiving part 5a having a short length in the longitudinal direction of the handrail bar 4 is provided on the handrail 3, the cylindrical handrail bar 4 is placed on the receiving part 5a, and the receiving part 5a is inserted. Then, the small screw 6 is screwed into the handrail bar 4. When the handrail bar 4 has a quadrangular cross section, the upper surface of the receiving portion 5a is a flat surface. Generally, the receiving portion 5a is matched to the shape of the lower surface of the handrail bar 4.

In FIG. 8, an annular receiving portion 5b having a short length to which the handrail bar 4 can be fitted is integrally provided on the upper part of the handrail 3. Then, in order to stop the movement of the handrail rod 4 inserted in the annular receiving portion 5b in the longitudinal direction, the handrail rod 4 is inserted through the annular receiving portion 5b.
Screwed into.

[Problems to be Solved by the Invention] In the handrail shown in FIG. 7, when the handrail bar 4 is made of a light alloy, only the small screw 6 is used to stop the handrail, so that the strength of the threaded portion is weak.

In the handrail shown in FIG. 8 described above, since the annular receiving portion 5b travels more than the handrail bar, there is a drawback that if the hand slides on the handrail rod 4 in the longitudinal direction, the annular receiving portion 5b will be hit by the hand. In the case of a handrail such as a handrail that slides a hand, the annular receiving portion 5b may have to be processed into a spherical shape, and even if it is spherical, it becomes an obstacle for the hand to slide on the handrail rod. Further, the handrail 3 must be attached to the wall 2 with the handrail bar 4 inserted through the annular receiving portion 5b during assembly, and the handrail bar 4 cannot be attached later. There is also a drawback that the machine screw 7 must be screwed in to stop the movement of the handrail bar 4 in the axial direction. Further, when inserting the handrail bar 4 into the annular receiving portion 5b, the surface of the handrail bar 4 may be damaged.

Although the machine screws 6 and 7 are used in the handrails shown in FIGS. 7 and 8, if the female screws into which the machine screws 6 and 7 are screwed are opened beforehand, the construction becomes extremely difficult. Therefore, the machining of holes or tapping must be carried out, and it has a common defect that it becomes a field work.

An object of the present invention is to solve the above-mentioned problems in the assembly type handrail and to provide a handrail that is easy to assemble and has a strong mounting.
