Description

[Detailed Description of the Invention] This invention relates to a cap for connecting handrails at the corner portions of handrails installed, for example, on stairs, balconies, or rooftops.

Generally, if the corner radius of the handrail is small, it is difficult to integrally form the handrails on both sides of the corner. Construction methods such as placing the walls close together were adopted. However, the former, that is, increasing the radius, not only results in wasted material, but also makes construction difficult in cases where space is restricted, such as stairs, and the latter, that is, making the ends of the caps close together, It was easy to get one's hand caught in the gap between the two caps, resulting in problems such as unexpected accidents.

This idea was devised in view of the above circumstances, and its gist is that mounting recesses are provided at both ends of the synthetic resin upper cover and the metal lower cover, which can match each other, to accommodate the Kasagi ends. A reinforcing part that protrudes downward is provided at the center of the back surface of the upper cover, and a fixing screw that can be screwed together with a screw hole provided on the lower surface of this reinforcing part is screwed through the lower cover. The ends of the caps are clamped and fixed in the mounting recess of the cover to connect the caps to each other, making it possible to easily and firmly connect the caps with a small number of materials. To provide a cap for connecting handrails, which is characterized in that the caps can be connected to each other by selectively using any shape without being restricted by the radius of the corner part or the like.

Examples of this invention will be described below based on the drawings.

Figure 1 shows a perspective view of the connecting cap of this invention used at the corner 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 handrails 1 and 2. These handrails 1, 2, and 3 are all as described later. For example, there is a metal base 6 having an insertion groove 5 for attaching the handrail 4 which opens at the lower center surface, and a synthetic resin such as vinyl chloride or rubber which is coated on the top and both sides of this metal base 6. It has a cap 8 made of a covering material 7. The caps of adjacent handrails 1, 2, or 3 are connected to each other by an upper cover 9 made of synthetic resin and a lower cover 10 made of metal, which constitute the connecting caps of this invention.

Figures 2 to 4 show a first embodiment of this invention, in which both ends of an elbow-shaped upper cover 9 made of synthetic resin and lower cover 10 made of metal are divided into two parts so that they can match each other. There are mounting recesses 9a, 9a; 10 that should respectively swallow the ends of the cap 8.
a, 10a are provided, and an upper cover 9
Reinforcing portions 11, . Screw holes 13, 13 are provided on the lower surfaces of both ends of the reinforcing portions 11, . Then, fixing screws 12, 12 are inserted into the reinforcing portions 11, . By screwing into the holes 13, 13, the upper and lower covers 9, 10 are fixed, and the ends of the caps can be clamped and fixed in the mounting recesses 9a, 10a of these covers 9, 10. In this case, the mounting recesses 10 at both ends of the lower cover 10
There are mounting holes 1 on the bottom of both sides of a and 10a.
5 and 15 are drilled, and this mounting hole 15
The lower cover 10 is connected to the Kasagi 8 by screwing the mounting screws 17 to the screw holes 16 provided on the lower surface of the Kasagi 8, that is, the metal base 6, through the screws, thereby improving the strength of the connection. It is designed so that you can figure it out.

5 and 6 show a second embodiment of this invention, in which the reinforcing portions 11, . . .
This is a case in which the upper and lower covers 9 and 10 are connected at 1' and the seam between the upper and lower covers 9 and 10 is hidden from the outside. That is, reinforcing parts 11, . , locking claw portions 18, 18 bent inward are provided at the lower ends of both side walls 9b, 9b of the upper cover 9, respectively.
, and these locking claws 18, 18 are attached to the lower cover 1.
This is a case in which the seam between the upper and lower covers 9 and 10 is hidden from the outside by engaging with the lower end surfaces of both side walls 10b and 10b of 0. Note that in the second embodiment, other parts are the same as those in the first embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

7 and 8 show a third embodiment of this invention, in which upper cover 9 is provided on both sides of upper cover 9.
Reinforcement parts 11, 11 are formed along the length direction of the reinforcing parts 11, 11, and screw holes 13, .
This is a case where ... is provided and consideration is given to further improve the reinforcing effect.

In the third embodiment, the parts other than the metal base 6' are the same as in the previous embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

In the above embodiment, the cap 8 is inserted into the baluster insertion groove 5.
Although the case is shown in which the covering material 7 is applied to the top surface and both side surfaces of the metal base 6 having a It can be connected to Further, although the above embodiment describes the manner in which the corner portions of the stair handrail are connected, it is of course not limited to only the stair handrail.
A similar connection can be made at the corner of a handrail on a balcony or rooftop as shown in the figure, or a corner of a wall handrail as shown in FIG. 10, and the same effect can be obtained. In this case, although only the outer corner portion is illustrated, it goes without saying that the same applies to the inner corner portion.

As explained above, the connecting cap of this invention is provided with mounting recesses for swallowing the ends of the cap at both ends of the synthetic resin upper cover and the metal lower cover, which can match each other, and the upper cover. A reinforcing part that protrudes downward is provided in the center of the back surface of the reinforcing part, and a fixing screw that can be screwed into the screw hole provided on the lower face of this reinforcing part is screwed together through the lower cover. Since the ends of the caps are clamped and fixed in the mounting recesses to connect the caps, it is possible to easily and firmly connect the caps with a small number of materials, and the radius of the corner can be adjusted. It can be made as small as possible, and
Excellent effects such as being able to selectively use any shape of handrails to connect handrails without being restricted by the orientation of the handrails are achieved. In addition, according to the connecting cap of this invention, the lower cover is made of high-strength metal and the upper cover is made of synthetic resin similar to the texture of the upper surface of the cap, so it is lightweight, strong, and inexpensive. It has the effect of approximating the texture of the capstone part of the entire handrail, and its utility value is remarkable.
