Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a corner cap of a handrail cap that is attached to a corner of a handrail installed, for example, on a staircase, balcony, or rooftop.

Generally, when the curvature of the corner of a handrail is small, a corner cap is used to connect two handrail caps. Corner caps usually consist of upper and lower covers, and by combining these upper and lower covers with a fixing means, the ends of the two handrail caps can be attached. Something that is meant to be swallowed is used.

However, since the upper and lower covers work together to attach the upper and lower covers to the handrail cap, it is impossible to temporarily attach only one of the upper and lower covers to the handrail cap. When it is necessary to attach a corner cap to a certain location, it is necessary to connect the upper and lower covers one by one, which is an inefficient work procedure.

The present invention has been made to solve this problem, and is designed so that only the lower cover can be temporarily attached to the handrail caps, and after first attaching only the lower cover to all the handrail caps, the upper cover can be temporarily attached to the handrail caps. An object of the present invention is to provide a corner cap for a handrail shank with improved installation efficiency by making it possible to take a work procedure such as sequentially fixing the covers to these lower covers.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a perspective view of the corner cap of the present invention used in the corner part of a stair handrail.
In the figure, 1 is the handrail on the upper floor, 2 is the handrail on the lower floor, and 3 is the handrail on the landing located between these two handrails 1 and 2. These handrails 1, 2, and 3 are all as described below. , a metal base 6 with an insertion groove 5 for attaching the handrail 4 facing downward and continuously opened in a longitudinal manner on the lower center surface, and a metal base 6, which is attached to the top surface and both sides of the metal base 6, for example. It has a cap 8 made of a synthetic resin such as vinyl chloride or a covering material 7 made of rubber. Corner caps of the present invention are attached to the end portions of the caps of the two handrails 1, 2, or 3, which are arranged substantially perpendicular to each other.

FIG. 2 shows a first embodiment of the corner cap of the present invention, which is made of a synthetic resin material and has an approximately L-shape in plan view, and includes an elbow-shaped upper cover 9 that is divided into two parts so that they can match each other. , mounting recesses 9a, 9a: 10a, 10a are provided at the ends of the lower cover 10, each swallowing the end of the cap 8,
Screw holes 12, 12, . . . for fixing screws 11 serving as fixing means are provided at appropriate locations on the peripheral edge of the upper cover 9.

On the other hand, the lower cover 10 has the screw holes 12, 12.
Through-hole 1 for insertion of fixing screw 11 that can match with...
3, 13, . Above gold stand 6
A locking protrusion 14' is formed to resiliently engage a locking recess 5' formed at the top of the insertion groove 5.

Therefore, in order to attach the corner cap of the present invention configured as described above to the end of the cap 8 and connect the two caps 8, 8, first, the caps that are disposed substantially orthogonally are attached. 8, Insert the lower cover 1 into the insertion groove 5 of 8.
0 guide 14, and then the lower cover 10
When pressed upward, the locking protrusion 14' of the lower cover 10 elastically engages with the locking recess 5' of the metal base 6,
This lower cover 10 is temporarily fixed to the metal base 6.

After that, the upper cover 9 is matched with the lower cover 10, and the fixing screws 11 are screwed into the screw holes 12 of the upper cover 9 through the insertion holes 13 from below the lower cover 10, and both covers 9, 10 should be fixed.

In this case, the mounting recess 9 of the upper cover 9
a is approximately U-shaped so that the upper half of the Kasagi 8 can be fitted into it, and the mounting recess 10a of the lower cover 10 is approximately V-shaped so that the lower half of the Kasagi 8 can be fitted thereto. It is formed in

Further, in this first embodiment, the guide 14
and a metal base 6 formed on the guide 14.
4' is fixed by elastically engaging the locking recess 5' of the insertion groove 5, but the guide 1
In addition to this, in order to fix the guide 14 and the metal base 6 to the metal base 6, for example, as shown in FIGS. Mounting screws 15 that pass through provided mounting holes 16 may also be used.

In this case, as shown in FIG.
The guide 14 may be formed by protruding the periphery of the guide 6 .

In addition, in the modification shown in FIG. 5,
The upper and lower covers 9, 10 are formed by press-forming metal members, and a fixing fitting 21 having a flange portion 20 with screw holes 12, 12, etc. is brazed to the back surface of the center portion of the upper cover 9, and the lower cover 10
It is pressed into a bent shape with both sides and the center facing upward to provide strength.

6 and 7 show a third embodiment of the present invention, in which the lower cover 1 is
This is a case where it is possible to fix the value to 0.

That is, the mounting recess 10a of the lower cover 10
A threaded groove 16a along the insertion groove 5 of the cap board 8 is provided in the guide 14 provided in the guide 14, and on the other hand, only the metal base 6 with the covering material 7 removed is protruded from the end of the cap board 8, and the top of the metal base 6 is Through-hole 1 for inserting screw 15 into
This is a case where the lower cover 10 is fixed to the cap board 8 by drilling a hole 7 and screwing the mounting screw 15 into the thread groove 16a through the insertion hole 17.

8 and 9 show a fourth embodiment of the present invention, in which a fixing member 22 for fixing the metal lower cover 10 to the cap 8 is separately formed. That is, the fixing material 22 is the horizontal substrate 22a,
A pair of vertical walls 22b stand up oppositely on this horizontal substrate 22a and jointly form the thread groove 16a,
22b, and the vertical wall 22 of this fixing member 22
b, 22b into the mounting recess 10a of the lower cover 10
The insertion hole 1 is made to protrude upward through a pair of slits 23, 23 provided in the metal base 6, and is fitted into the insertion groove 5 of the cap 8, and is bored at the top of the metal base 6.
This is a case where the lower cover 10 is fixed to the cap 8 by screwing the mounting screws 15 into the thread grooves 16a through the screws 7.

FIG. 10 shows a fifth embodiment of the present invention,
A case is shown in which a caulked portion 14'' is protruded from the upper surface of the guide 14 provided on the lower cover 10, and after this caulked portion 14'' is penetrated into a through hole 17 provided in the metal base 6, the protruding portion is caulked. It is something.

In each of the above embodiments, a corner cap attached to a corner of a stair handrail is described, but it is of course not limited to only a stair handrail, and can be used, for example, on a balcony as shown in FIG. It may be attached to the corner of a handrail on a rooftop or the like, or the corner of a wall handrail as shown in Figure 12, and it can also be used not only at an external corner but also at an internal corner. .

As is clear from the above description, according to the corner cap of the handrail cap of the present invention, a guide that fits into the insertion groove of the handrail cap is provided protrudingly, and the guide is fixed to the handrail cap and connected to the upper cover. Since it is now possible to temporarily attach only the lower cover to the Kasagi without collaboration, when constructing the handrail, first attach only the lower cover to all corners, and then attach the upper cover to this lower cover. It is possible to take the construction procedure of fixing the

Therefore, it is possible to improve the mounting efficiency of the corner cap and to improve the efficiency of constructing the handrail.
