Description

[Detailed description of the invention] The present invention relates to handrails installed in various places such as balconies, stairs, and hallways of buildings, and in particular to handrails that have a synthetic resin cap cover removably attached to the outer circumferential surface of the cap. It is related to.

Most modern handrails are made of aluminum, but aluminum has the drawbacks of being easily damaged and expensive. To deal with this, if you use steel, etc., it is superior to aluminum in terms of strength, but the surface must be painted to prevent rust, etc.
Its maintenance requires time and money. Also, since the metal is exposed on the surface of the Kasagi,
If someone accidentally fell near the handrail, the hat could hit them hard on the hand or head, causing an unexpected injury.

In addition, in order to solve this problem, the surface of the handrail was covered with an outer covering (Utility Model Publication No. 51-33703).
(Japanese Utility Model Publication No. 41-22842), the locking convex stripes and the locking grooves formed on both side edges of the outer cover are fitted and locked to each other so that they can be attached and removed (Utility Model Publication No. 41-22842). ) has also been proposed. However, in the former case, the outer cover is not removable, so maintenance is time consuming, and in the latter case, when the outer cover is twisted, the latching protrusions and the latching grooves are separated. Since the lock is easily released, the outer cover has the disadvantage of falling off during use.

The present invention was made to eliminate the above-mentioned drawbacks, and provides a handrail that has excellent strength, is simple and inexpensive to maintain, improves safety, and does not allow the outer cover to fall off easily during use. The purpose is to provide

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

In FIG. 1, a cap 1 used for the handrail of the present invention is shown, and is formed by covering the outer peripheral surface of a cap core 2 with a cap cover 3.

The Kasagi core material 2 is made of metal such as iron and is formed into a long cylindrical shape. Although FIG. 1 shows the cross-section as circular, the present invention is not limited to this, and the cross-section may be oval, rectangular, or various other shapes.

A Kasagi cover 3 is removably placed over the outer peripheral surface of the Kasagi core material 2. This Kasagi cover 3 is
It is extruded from a soft synthetic resin material such as vinyl, and has approximately the same length as the Kasagi core material 2, as shown in FIG. The outer surface of the Kasagi core material 2 has a width such that the outer surface thereof and the inner surface of the other side edge portion 5 slightly overlap each other, and covers the entire outer circumferential surface of the Kasagi core material 2. Two hook-shaped locking ridges 6 protruding outward from the Kasagi core material 2 are provided on the outer surface of one side edge 4 in the longitudinal direction of the Kasagi cover 3, and the inner surface of the other side edge 5 A locking recessed line 7 having a shape that fits and locks with the locking convex line 6 is formed toward the inside of the Kasagi core material 2 .

Therefore, in order to cover the Kasagi cover 3 over the Kasagi core material 2, as shown in FIG. Wrap the other side edge 5 in contact with the one side edge 4.
The locking protrusion 6 on the one side edge 4 is brought upward.
What is necessary is to fit the locking groove 7 on the other side edge to lock it.

The cap 1 constructed as described above is supported by a holding member and is disposed along a wall surface or the like to form a handrail.

2 and 3 show a first embodiment of the handrail of the present invention, which is installed on a staircase. In this case, the cap 1 is disposed using a handrail 13 erected on the stair step as a holding member.

On the other hand, at the upper end of this handrail 13, there is a fitting piece 1 that protrudes below the locking grooves 7, 7 of the Kasagi cover 3.
C located between 5 and 15
An upper rail 14 of the shape member and a support piece 17 which is interposed in the C-shaped groove of the upper rail 14 and abuts on the intermediate surface of the locking grooves 7, 7 of the Kasagi cover 3 are disposed. 1 is fixed to the handrail 13 via a support piece 17 using screws or tassel pin screws 16. In addition, screws or tatsupin screws 16
The driving point is an intermediate position between the handrails 13, 13, but the support piece 17 may be interposed along the entire length of the upper rail 14, or it can be inserted only at the driving point of the screw or tatsupin screw 16. It may be something that intervenes.

FIGS. 4 and 5 show a second embodiment of the handrail of the present invention, in which it is attached to a wall such as a hallway. In this case, the cap 1 is disposed using a bracket 18 attached to the wall as a holding member.

In this embodiment, the support piece 17 is integrally formed at the tip of the bracket 18, and has a fitting recess into which the support piece 17 of the bracket 18 can fit between the locking grooves 7, 7 of the Kasagi cover 3. 20 is provided, and after fitting the fitting recess 20 and the support piece 17,
The cap 1 is arranged and fixed by driving screws or tatupin screws 21 through the support piece 17, the cap cover 3, and the cap core 2.
The screws or tuft pin screws 21 may be driven into two locations depending on the area of the support piece 17.

As explained above, in the present invention, the locking protrusions 6 or the locking grooves 7 are provided on both side edges of the Kasagi cover 3 made of synthetic resin, and the locking protrusions 6 and the locking grooves 7 are connected to each other. By fitting, the Kasagi cover 3 is attached to the outer peripheral surface of the Kasagi core material 2, and the support piece 17 of the retaining material is brought into contact with the intermediate portion of the locking grooves 7, 7, so that the Kasagi 1
After removing it from the holding material, the cap 3 can be easily removed from the cap 2 by disengaging the locking protrusion 6 and the locking groove 7. Therefore,
Even if the Kasagi cover 3 is worn out or damaged due to use, it can be easily replaced with a new one, and since the Kasagi cover 3 will not come off unless the Kasagi 1 is removed from the holding material, the Kasagi cover 3 can be easily removed during use. It is possible to prevent the cover 3 from coming off.

In addition, even if iron or the like is used as the Kasagi core material 2, surface painting is not required for rust prevention, and the Kasagi cover 3 can be easily removed and reattached as described above even during use, so it can be repainted. Maintenance and maintenance can be carried out easily and inexpensively without the need for such labor and expense. Furthermore, since no metal is exposed on the surface of the cap 1, even if you accidentally fall and hit your hand or head on the cap, the cushioning effect of the cap cover 3 will prevent unexpected accidents and improve safety. can. Furthermore, since the surface of the Kasagi cover 3 can be provided with various uneven shapes and colors, it has effects such as being able to exhibit the decorative effect of the handrail.
