Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a connecting part of a capstone at a corner part of a handrail installed, for example, on a staircase, balcony, or rooftop.

Generally, when the radius of the handrail corner is small, it is difficult to form the handrails on both sides of the corner integrally. Construction methods such as placing the parts 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, There was a problem in that it was easy for people to get their hands caught in the gap between the two caps, resulting in unexpected accidents.

This invention has been made in view of the above circumstances, and its gist is that an insertion receiving part formed for attaching a handrail to the lower surface of a cap tree of an adjacent handrail has an elongated rectangular cross section, In addition, the ends of the connecting core material each having a substantially L-shape in plan view are engaged and fixed to connect two adjacent caps in a substantially L-shape in plan view, and the ends of the caps are swallowed. , and the upper cover and lower cover are matched so as to contain the connecting core material, and by connecting these upper and lower covers, both the caps of adjacent handrails are connected to each other. The suri can be formed integrally, and
The radius of the corner part can be made as small as possible, and the caps of both handrails can be connected easily and firmly by selectively using any shape without restricting the direction of the handrail. The purpose is to provide a structure for connecting the wooden handrails.

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

FIG. 1 shows a perspective view when the structure of the connecting part of the present invention is applied to the corner part of a staircase 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 lower floor.

Similarly, a guide groove 10b having reinforcing ribs 10c is provided on the rear side (see FIG. 7), and as shown in FIG. By guiding and holding the connecting core material 11 in the grooves 9b, 10b in a fitted manner, the upper and lower covers 9, 10 and the connecting core material 11 are engaged with each other, thereby making it possible to further strengthen the connection between the caps. There is.

In this case, if at least one of the upper and lower covers 9 and 10 is provided with a guide groove 9b or 10b having a reinforcing rib 9c or 10c, the above object can be achieved. The guide groove 9b of the cover 9 is continuous, and the guide groove 10b of the lower cover 10 is formed into two separate parts.For example, as shown in FIG. Both can be made into two, or conversely, both can be formed into one, and the form can be arbitrarily selected. In this embodiment, the same parts as in the first embodiment are denoted by the same reference numerals, and the explanation thereof will be omitted.

9 and 10 show a third embodiment of the present invention, in which the upper cover 9 is designed to have further strength. That is, the engaging portions 11a, 11a of the connecting core material 11 are provided on the back surface of the upper cover 9.
A reinforcing protrusion 1 extending toward both sides from the top of the
A pair of parallel reinforcing ridges 9d, 9 abutting on 1b
d is formed, and the upper cover 9 is held by the connecting core material 11 in the connected state. In addition, in this third embodiment, other parts are the same as those in the previous embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

FIGS. 11 and 12 show a fourth embodiment of the present invention, in which the upper and lower covers 9, 10 are reinforced and a proper connection that can accommodate dimensional errors in the handrail is achieved. That is, the connected core material 1
A substantially T-shaped reinforcing plate 17 is provided protruding from substantially the center of the connecting core material 11, and the engaging portions 1 are provided at both ends of the connecting core material 11.
1a and 11a are respectively fitted with fixing plates 18 and 18 which are slidable relative to the connecting core material 11 therein, and mounting screws 15 and 15 are inserted through mounting holes 16 and 16 drilled in the fixing plate 18. It can be screwed into screw holes 19, 19 provided at the end of the Kasagi, that is, the metal base 6, and the upper and lower ends of the reinforcing plate 17 are fitted into the opposing surfaces of the upper and lower covers 9, 10, respectively. At the time of connection, the fixing plates 18, 18 are moved according to the dimensional error of the handrails 1, 2, or 3, and after coming into contact with the ends of the Kasagi 8, the mounting screws 15 are attached. Connected core material 1
1 is temporarily connected between the Kasagi 8 and 8, and after fitting the receiving grooves 9e and 10d of the upper and lower covers 9 and 10 into the reinforcing plate 17 so as to match each other, the Kasagi are fixed with the fixing screws 12. This is a case where they are connected to each other. In the fourth embodiment, other parts are the same as those in the previous embodiment, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

In addition, in each of the above embodiments, the upper and lower covers 9 and 10 are screwed into the fixing screw 1 that is screwed in from below the lower cover 10.
2 is shown, but it is not necessarily necessary to fix between the top and bottom; for example, as shown in FIG. 13, fixing screws 12,
12 may be screwed in to fix the upper and lower covers 9, 10.

Further, in each of the above embodiments, the structure of the connection part of the corner part of the stair handrail is explained, but of course it is not limited to only the stair handrail, and for example,
It can be similarly applied to the corner of a handrail on a balcony or rooftop as shown in FIG. 4, or to the corner of a wall handrail as shown in FIG. 15, and has the same effect. 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, according to the present invention, the caps of adjacent handrails are connected to each other by using the insertion receiving portions formed for attaching the handrails to the caps.
By engaging and fixing the end of the connecting core material in this insertion receiving part, two adjacent caps are connected in a substantially L-shape in plan view, and the end of the caps is swallowed and the connecting core is enclosed. Since the upper cover and lower cover are matched with each other and the upper and lower covers are connected by a fixing means, any shape can be selectively used without being restricted by the direction of the handrail or the radius of the corner part. .

In addition, by engaging and fixing the connecting core material from the lower side to the insertion receiving part that is formed to attach the handrail and opens downward, the two caps are connected, so the caps are arranged. The two caps can be connected even after they are fixed, and there is no need to connect the caps using a connecting core material in advance when installing the handrail.

Therefore, it is possible to avoid the labor-intensive work of arranging long, connected handrails, and it is possible to improve the efficiency of the handrail installation work.

Furthermore, as mentioned above, since the two caps can be connected even after the handrail is installed, it can also be applied to existing handrails that are placed facing each other at approximately right angles. .

Furthermore, in handrails with handrails, the connecting core material is engaged and fixed using a generally formed insertion receiving part, so it can be used for other purposes without making any new changes to the cap. It can be used for various types of handrails.

In addition, since the ends of the Kasagi are swallowed by the upper cover and the lower cover, which are generally L-shaped in plan view, the ends are not exposed to the outside, and an excellent design effect can be achieved. Accidents such as a hand being caught in the gap can be reliably prevented without creating a gap between the ends of the two caps.
