Description

[Detailed explanation of the idea] This idea concerns handrails.

As shown in FIG. 1 and FIG. 2, the conventional handrail has a bracket 1 provided with a pair of opposing plates 2 and 3.
A connecting fitting 4 is interposed between the three.

The connecting fitting 4 is bent into a U-shape, and has stepped portions at the tips of both end pieces that widen the facing width, and furthermore, the tip edges 6 are inclined inward.

Further, screw insertion holes 7 are formed in the facing plates 2 and 3, and opposite thereto, a screw insertion hole 8 is formed in one end piece of the connecting fitting 4, and a screw hole 9 is formed in the other end piece.

The Kasagi 10 has a substantially elliptical cross section with a gap 11 formed on the lower surface, and a support portion 12 is provided at the central portion corresponding to the short axis. The mounting screw 13 is screwed into the screw hole 9 through the holes 7 and 8, and the distal end is narrowed using the intermediate piece 4a of the connecting fitting 4 as a fulcrum, thereby clamping and holding the support part 12 of the cap 10.

However, this handrail is attached to the Kasagi 10 in the direction A in FIG.
When an external force is applied to the connecting fitting 4, plastic deformation tends to occur in the parts a and b of the connecting fitting 4 on the side where the tensile force is applied, resulting in a quality problem.

In addition, since the intermediate piece 4a of the connecting fitting 4 serves as a fulcrum on which both end pieces tilt, in order to widen the range of inclination, it is necessary to distance the screw hole 9 and the screw insertion hole 8 from the intermediate piece 4a, that is, increase the height. However, there is a drawback that the connecting fitting 4 becomes large in size.

Therefore, the purpose of this invention is to increase the strength of the Kasagi attachment,
Moreover, it is an object of the present invention to provide a handrail whose connecting fittings can be made compact.

An embodiment of this invention is shown in FIGS. 3 and 4.

That is, this handrail includes a bracket 14 and a connecting fitting 15.
, a Kasagi 16 and a mounting screw 17, the bracket 14 has a wall mounting plate 18 formed at one end and a mounting hole 19, and a pair of opposing plates 20 and 21 are erected on the upper surface of the other end. are doing.

The opposing plates 20 and 21 each have screw insertion holes 22 and 23 formed in the center, and a fulcrum projection 2 between the opposing plates 20 and 21.
4 is formed.

The connecting fittings 15 consist of a pair, and the first connecting fitting 15a has an overhanging plate 25 that extends laterally on the periphery except for the upper end, and a cap 16 is fixed to the upper side of the extending plate 25. A support protrusion 26 and a locking recess 27 are formed, and a screw insertion hole 28 is formed slightly below the center of the connecting fitting 15a.

The second connecting fitting 15b also has substantially the same configuration, but has a screw hole 29 instead of the screw insertion hole 28, and other parts are given the same reference numerals.

The Kasagi 16 has the same configuration as that shown in FIG.

For assembly, a plurality of brackets 14 are attached at predetermined intervals using wood screws 14'.

The first connecting fittings 15a are interposed between the front facing plate 20 of each bracket 14 and the fulcrum protrusion 24, the projecting plate 25 is directed toward the rear facing plate 21, and the screw insertion hole 22.
8 to each other.

The projecting plate 25 of the second connecting fitting 15b is connected to the first connecting fitting 1.
5aK, the screw hole 29 and the screw insertion hole 2 are interposed between the fulcrum protrusion 24 of the bracket 14 and the rear facing plate 21, and
Align 3.

The cap 16 is fitted between the locking recess 27 at the upper end of the first connecting fitting 15a and the second connecting fitting 15b, and the bracket 1
Insert the mounting screw 1 through the screw insertion hole 22 of the front facing plate 20 of No. 4.
7 and screwed into the screw hole 29 of the second connecting fitting 15b, and further position the tip of the mounting screw 17 in the screw insertion hole 23.

When the mounting screw 17 is tightened, the second connecting fitting 15b
is attracted to the connecting fitting 15a of the second connecting fitting 15a.
The side edge of the overhang plate 25 of b is supported by the fulcrum projection 24 and tilted, thereby narrowing the width of the locking recess 27 at the upper end.
Clamp the support part 6.

This configuration provides the following effects.

That is, (1) since the Kasagi locking recess 27 is formed in the overhanging plate of the connecting metal fitting 15, the deformation of the connecting metal fitting 15 can be minimized and the strength can be increased compared to the conventional art.

(2) Since the side edge of the lower end of the overhang plate 25 is supported by the fulcrum protrusion 24, deformation of the connecting fitting 15 at the fulcrum can also be prevented.

(3) Since the fulcrum protrusion 24 serving as a fulcrum is provided on the bracket 14, there is no need to make the screw insertion hole 28 and the screw hole 29 of the connecting fitting 15 higher than the lower end compared to the conventional case.

As described above, in the handrail of this invention, a pair of connecting metal fittings are formed, and an overhang plate with a locking recess is provided on the periphery, while a fulcrum protrusion is provided on the bracket, increasing the strength for attaching the Kasagi. This has the effect of preventing deformation and making it possible to downsize.
