Description

[Detailed description of the invention] This invention relates to handrails installed on stairs or balconies, for example, and specifically relates to a metal base that is screwed to the upper ends of hollow pipe-shaped standers and connects the upper ends of these standers, and a metal base that connects the upper ends of these standers. The present invention relates to an improvement in a handrail cap made of a covering material having a substantially C-shaped cross section and applied to the upper part of the metal base so as to cover the metal base.

When installing handrails on stairs, etc., a plurality of standers are erected on the stairs, and a handrail cap, which is formed by covering a metal base with a covering material, is fixed to the upper end of the standers. However, no handrail cap that reliably fixes a long handrail cap to the upper ends of a plurality of pipe-shaped standers has yet been proposed.

The present invention was developed in response to these circumstances, and aims to provide a handrail cap that can securely fix the metal base of the handrail cap on the stand and has an excellent design. purpose.

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

1 to 3 show a first embodiment of this invention, which is embodied as a handrail cap 2 for a handrail placed on a staircase A.

This Kasagi 2 is arranged in an inclined manner at the upper end of a plurality of pipe-shaped standers 1, 1 . . . erected on the stairs A, and as shown in FIGS. The upper part of this metal base 4 is covered. For example, the covering material 5 is made of synthetic resin such as vinyl chloride, rubber, or the like.

The metal base 4 has side walls 8, 8 for securing the covering material erected on both sides of its upper part, and a protrusion 9 is provided above the center part, and the width becomes narrower as it goes downward. Each of the support seats 15 is formed with a protruding support seat 15, and as shown in FIG. has been done.

As shown in FIG. 2, the protrusion 9 of this metal base 4 is
Its upper surface projects slightly upward from the tops of the covering material locking side walls 8, 8 to form a gently arched top portion 9', and this side wall portion is formed into a downwardly expanding inclined surface 10,
10, and in at least one of these inclined surfaces 10, 10, a screw hole 6, which is bored substantially perpendicularly, is formed in an inclined shape downward from the upper part of the metal base 4. ing. Note that a V-groove 11 for marking is provided approximately at the center of the inclined surface 10 to facilitate the drilling of the screw hole 6.

The sheathing material 5 has a substantially C-shaped cross section that surrounds the sheathing material locking side walls 8, 8 of the metal base 4 on both sides, and has a gently arc-shaped protrusion 9 of the metal base 4 on the lower surface of its top. An arcuate groove 5' into which the top part 9' fits is provided, and when it is attached to the upper part of the metal base 4, three points are formed by the side walls 8, 8 for locking the covering material and the gently arcuate top part 9'. It is designed to be supported and put into a taut state, to strengthen the adhesion, to prevent sagging, and to prevent the covering material 5 from shifting.

Next, to explain the procedure for installing the handrail cap 2 shown in Fig. 1, first, prepare a piece with the upper end of the stand 1, 1... cut diagonally to match the inclination angle of the staircase A where it is to be installed. Then, after vertically standing up the standers 1, 1 at both ends of the staircase A on which the handrail will be constructed, and positioning the caps 2 by placing them on the upper ends, bury the lower ends of the standers 1, 1 in the staircase A. After fixing it to an anchor (not shown) by welding or the like, the metal base 4 constituting the Kasagi 2 and the standers 1, 1 at both ends are fixed with screws 7, and then the standers 1, 1 at both ends are fixed with screws 7. Multiple standing children 1, 1 with appropriate intervals between 1, 1
After inserting the upper end into the stand insertion groove 3 of the metal stand 4 and fixing it with the screw 7 in the same way, and fixing the lower end of each stand 1 to the anchor, the covering material 5 is placed on the upper part of the metal stand 4. to complete the assembly.

Figures 4 and 5 show the case where the handrail cap of the present invention is applied to other handrails.
A pair of pillars 1 erected at appropriate intervals, etc.
This is a case in which a plurality of standers 1, 1, . Note that the lower end of each stand 1 is the same as the first embodiment except that it is connected to the lower chord member 13 that connects the lower parts of the columns 12, 12, so the same parts are given the same reference numerals and the explanation thereof will be omitted. do.

As is clear from the above description, according to the handrail cap according to the present invention, the upper surface of the protrusion protruding from the center of the metal base is a gently arched top that fits into the arcuate groove of the covering material. Therefore, displacement of the sheathing material can be reliably prevented, and the sheathing material is supported at three points by the sheathing material locking side wall of the metal base and the circular arc groove and is applied under tension. The covering material can be reliably attached without sagging or the like occurring at any part.

Furthermore, in order to fit the covering material and the metal base,
Since the protrusion is provided on the side of the metal base and the support seat is bulged out below the center of the metal base, it is possible to deepen the pedestal insertion groove drilled inside the pedestal. The metal base can be securely and firmly fixed, and its installation strength can be increased.

In addition, the part that protrudes upward from the metal base is used as a slot for inserting the stand, and the width of the support seat becomes narrower as it goes downwards, so even though the size of the stand to be swallowed is deepened. , it is possible to reduce the thickness of the entire handrail, and to obtain a handrail cap that is stylish in terms of design.

In addition, since the screws that fix the stand and the metal base are screwed together in an inclined manner with respect to the stand, it is possible to fix even pipe-shaped rods that are normally used as the stand. Since the penetration length inside the part is longer, the screw can be reliably screwed into the stand.

Furthermore, since the side wall portion of the protrusion is formed as an inclined surface that spreads downward, the holding length of the screw can be increased, and wobbling of the screw is completely prevented, thereby preventing wobbling of the metal base on the stand. In addition, since the head of the screw is completely covered by the metal base and the covering material, it has various effects such as not impairing the appearance and being able to effectively protect it from corrosion. A metal stand screwed to the upper ends of the hollow pipe-shaped standers to connect the upper ends of these standers, and a covering having a substantially C-shaped cross section that is applied to the upper part of the metal stand so as to cover the metal stand. It is possible to provide the best structure for a handrail hat made of wood.
