Description

[Detailed explanation of the invention] <Industrial field of application> This invention is a handrail cap (not necessarily made of wood, but made of metal, plastic, etc. Regarding corner fittings (with).

<Prior art> Conventionally, there is no particular problem when the handrail caps of various buildings are installed in a straight line, but in many cases they are not only installed straight but also bent at right angles or other angles, and in such cases, Metal parts are joined at a predetermined angle by welding, or wooden parts are joined using adhesive and tenon fitting to maintain a fixed angle, or are connected using connecting fittings. It was hot. and,
As a finishing touch, the entire surface of the Kasagi was coated with resin or a decorative coat of aluminum was applied.

<Problem to be solved by the invention> However, in any of the above conventional examples, it is constructed integrally and unchangeably so as to form a predetermined angle according to the construction site (based on the drawing). It was hot.

Therefore, installation work may not be possible unless both accurate design and faithful processing match each other, and even if installation work is possible, forced connections may be forced; Corner supports were necessary to maintain the strength of the section. In addition, in the case of repair work, it is not possible to process parts based on drawings as the work is often done by a different contractor than the original contractor, so if there is a replacement part, we will match it with the actual part, or if there is no replacement part, we will do it directly from the site. Dimensions had to be measured and then manufactured based on the measurements, which required skill and time, resulting in a lack of responsiveness and high costs.

The present invention attempts to solve the drawbacks of the above-mentioned conventional examples and provides a connecting device that can easily and accurately respond to any situation by preparing several types of connecting devices that match the Kasagi. It is something.

<Means for solving the problem> Two connecting bodies each having a half-shaped pivot piece protruding from the outer end of a connecting body connected to a cap, are connected to a flat surface of each pivot piece. The concave portion and convex portion formed in the two connecting pieces are fitted into each other, and both connecting pieces are pivotally connected by a shaft.

<Function> By connecting both connecting bodies to each other at the pivot pieces provided on both connecting bodies, both pivot bodies can freely move the connected caps around the axis of the pivot piece and the recessed fitting part. You can adjust the opening angle.

<Example> Hereinafter, the present invention will be described in detail with reference to an example shown in the drawings.The present invention connecting device A consists of two connecting bodies 3 and 9, and has caps a and b extending in two directions.
This is the joint between the two caps.
That is, a connecting body 3 that is attached to one end of a capstone a extending in one direction is provided with a fitting piece 2 protruding from one side to be connected to the capacitor a, and on the other side, an end surface of the connecting body 3 is provided with a fitting piece 2 extending in the lateral direction. A pivot piece 1 with a thickness of A shaft hole 6 is bored from the center toward the opposite side of the pivot piece 1.

Further, the connecting body 9 attached to the end of the capboard b extending to the other side is constructed approximately the same as the connecting body 3, but
The difference is that a recess 11 is provided in the center of the pivot piece 7 facing the pivot piece 1 to receive the protrusion 5 protruding from the pivot piece 1.

Then, the two connecting bodies 3 and 9 have their respective pivot pieces 1 and 7 facing each other, and the protrusions 5 and recesses 11 formed on each opposing surface are fitted, and holes are formed in both the pivot pieces 1 and 7. The shaft 13 is inserted into the shaft holes 6 and 12, and the connecting bodies 3 and 9 are connected freely in rotation.

In addition, the symbols 4 and 10 in the figure are the connecting bodies 3 and 9, respectively.
These are screw holes for securely fitting and holding each fitting piece 2, 8 and Kasagi a, b, and also for connecting bodies 3, 9.
A flat surface is formed on a part of each lower surface, but this is done in order to more reliably maintain the direction of the caps a and b and the connecting bodies 3 and 9, respectively. The outer shape of the connecting bodies 3 and 9 is finished to have a smooth spherical surface to give a good feel to the touch. or,
The sizes of the concave and convex portions shall be determined as necessary.

As mentioned above, the connecting device A of the present invention is constructed so that the intersecting angles of both the connecting bodies 3 and 9 constituting this can be freely changed by the shaft 13 (Fig. 5). A straight cap of a predetermined length is manufactured in advance, and this is attached to each of the fitting pieces 2 and 8 at the assembly site using the connector A of the present invention.
It is easily constructed by assembling the caps while fitting them into the ends of both caps a and b.

<Effects of the invention> By virtue of the above-mentioned configuration, the present invention eliminates the need to manufacture a factory etc. at a predetermined angle in advance when connecting two caps having different directions, and also improves processing accuracy (angle ), since the predetermined angle is inevitably determined, productivity is improved, and the work is extremely simple and easy since there is no need to make connections by welding or the like on site.

Furthermore, since the angle can be easily adjusted to any direction, work efficiency can be improved in repair work and the like.

In addition, since the two pivot pieces are fitted in a convex-concave manner, the connection between the two is stronger, and even if the shaft becomes loose, the two will not separate immediately, and will be connected only by the shaft. Unlike this, there is less play and it is more stable. Furthermore, since stable connection can be achieved as described above, it is a highly practical idea that has many excellent effects, such as eliminating the need for corner supports as in the past, making the structure simple and inexpensive to manufacture.
