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, when the curvature of the corner part of a handrail is small, a handrail connecting cap is used to connect two handrail caps. Because it is necessary to have a structure that allows the connecting cap to be attached to the connecting cap in the same state, the connecting cap is usually composed of upper and lower covers, and these upper and lower covers are combined using fasteners. , two handrail caps with the ends swallowed together are used.

In this case, the fastener is attached from the bottom cover side so that the head is not exposed to the outside and spoils the appearance, but the fastener is attached in an unnatural posture bent down. The work had the disadvantage of being very tedious.

On the other hand, in order to eliminate such drawbacks, the applicant fixed a fixture having a mounting hook on the upper cover, and elastically engaged the mounting hook with a slit in the lower cover. A connecting cap for connecting the upper and lower covers has been proposed (see Japanese Utility Model Publication No. 57-68033), but in this case, there is a problem in that it is necessary to separately manufacture fixing fittings and fix them to the upper cover. There is.

This invention was made in consideration of the above points, and an object of the present invention is to provide a handrail connecting cap that can easily connect the upper and lower covers without increasing the number of parts.

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 two handrails 1 and 2. These handrails 1, 2, and 3 will all be described later. For example, a metal base 6 having an insertion groove 5 for attaching a handrail 4 opening at the lower surface of the center.
and a covering material 7 made of synthetic resin such as vinyl chloride or rubber, which is applied to the upper surface and both side surfaces of the metal base 6. The caps of adjacent handrails 1, 2, or 3 are connected to each other by an upper cover 9 and a lower cover 10 that constitute the connecting cap of this invention.

Figures 2 and 3 show a first embodiment of the connecting cap of this invention, which is divided into two parts so that they can match each other, and is itself made of an elastically deformable material, such as synthetic resin. The elbow-shaped upper cover 9 and lower cover 10 each have mounting recesses 9 at both ends thereof to accommodate the ends of the cap 8.
a, 9a; 10a, 10a, and a substantially mushroom-shaped locking protrusion 9b with a swollen tip protrudes at an appropriate location in the center on the back surface of the upper cover 9. Stepped locking receivers 10b, . By mating and fixing the covers 9, 10 to each other by engaging them using force, the covers 9, 10 are
The ends of the caps 8 are clamped and fixed between the 10 mounting recesses 9a and 10a, and the caps of adjacent handrails are connected to each other. In this case, a guide portion 10c is provided in the mounting recess 10a of the lower cover 10.
The guide portion 10c is inserted into the insertion groove 5 of the cap 8, and the mounting screw 1 is inserted through the mounting hole 11 provided in the guide portion 10c.
2 to the metal base 6 of the Kasagi 8,
Although the lower cover 10 is connected to the cap 8 to provide a stronger connection structure, it is not necessarily necessary to provide the guide portion 10c.

4 to 6 show a second embodiment of this invention, in which locking protrusions having a substantially mushroom-shaped cross section protrude from both side edges of the upper cover 9 downward, that is, toward the lower cover 10 side. Locking protrusions 9b ₁ , ... are provided on both side edges of the lower cover 10, and locking receiving portions _{that can engage with and grip the locking protrusions 9b 1 are} provided on both side edges of the lower cover 10. The retaining grooves 10b ₁ , . . . are provided, and the engagement ratio between the retaining protrusions 9b ₁ and the retaining grooves 10b ₁ is increased compared to the embodiment described above to fix the upper and lower covers 9, 10 and connect the caps to each other. This is the case if you do it firmly.

7 to 9 show a third embodiment of this invention, in which locking protrusions 9b ₂ whose tips are bent outward are provided on both side edges of the upper cover 9, and the lower cover A slit 1 is provided on both side edges of the locking protrusion 9b2, which is a locking receiving portion that engages with the locking protrusion _9b2 so as to be able to grip the locking protrusion 9b2.
_0b2 is provided, and these locking protrusions _9b2 and slits 1
This is a case where the upper and lower covers 9 and 10 are fixed by engagement with _0b2 . In addition, lower cover 1
There is a mounting hole 1 at the bottom of the mounting recess 10a of 0.
1 is drilled.

10 to 12 show a fourth embodiment of this invention, in which two locking protrusions 9 are provided at the center of the upper cover 9, each of which has a plurality of bulges at its tips.
b ₃ protrudingly provided, and lock receiving grooves 10b 3 and 10b 3 that can hold the locking protrusion 9b ₃ are provided in the center part of the lower cover 10, and the locking grooves 10b ₃ and 10b ₃ that can hold the locking protrusion 9b 3 are connected to the locking protrusion 9b ₃ . Receiving groove 10
_This is a case in which the upper and lower covers 9 and 10 are engaged with each other at the center thereof, thereby serving as reinforcement when the upper and lower covers 9 and 10 are fixed. In addition, both side edges of the upper and lower covers 9 and 10 have locking claws 9 that engage with each other.
c and 10d are provided to prevent the generation of gaps between the upper and lower covers 9 and 10 when they are fixed.

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 Furthermore, 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; for example, the first
A similar connection can be made at the corner of a handrail on a balcony or rooftop as shown in FIG. 3, or a corner of a wall handrail as shown in FIG. 14, 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 is clear from the above description, according to the handrail connecting capacitor of the present invention, the locking protrusion and the locking receiver formed on the upper and lower covers are elastically engaged with each other, and the upper and lower covers are Since the upper and lower covers are connected together, it is easier to connect the upper and lower covers, improving the workability of installing handrails, and there is no need to separately manufacture or intervene with fixing fittings, etc. The number of points is reduced, and manufacturing costs can be reduced.
