Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for connecting inclined parts of handrails, fences, etc.

(Prior Art) When installing handrails on stairs or balconies, they may be installed partially diagonally or horizontally.

In such a case, it is necessary to connect the horizontal part of the handrail cap and lower crossbar so that it is continuous with the slope.

This also applies to fences attached to the periphery of buildings.

As a conventional coupling device of this type, the Utility Model 59-
The one shown in Japanese Patent No. 22839 is generally known. The one shown in this publication is connected by a universal joint consisting of a male joint member having a fitting recess and a female joint member having a fitting recess.

(Problems to be Solved by the Invention) However, according to the above-mentioned connecting device, since the connecting portion is pivoted by the convex portion and the concave portion, there is a risk that the connecting portion may be damaged or deformed if a force is applied from the side. Further, there was a problem that the connecting portion between the male joint member and the female joint member was exposed, resulting in poor appearance.

This invention was proposed in order to solve the above-mentioned conventional problems, and aims to provide a device for connecting inclined parts of handrails, fences, etc., which has extremely high connection strength and has a good appearance. purpose.

(Means for Solving the Problems) This invention involves attaching a first connector and a second connector to both ends of the horizontal beams to be connected, and connecting the first connector to the second connector. A handrail in which the side rails are connected to each other by connecting them;
An inclined part device such as a fence, which includes a fitting part that fits into one end of a crosspiece to which the first connector is to be connected, a collar part that covers an end of the crosspiece, and a protruding part at the tip of the fitting part. It is formed from an overhanging portion having an arcuate curved surface on one side and a protrusion protruding from the side surface of the overhanging portion, and a fitting portion for fitting the second connector into the other side beam and a sidewall. It is formed from a flange part that covers the end of the log and a storage part into which the overhanging part of the first connector is inserted, and inside the storage part, the first
It is characterized by an arcuate guide groove that engages the protrusion of the connector.

(Example) Hereinafter, this invention will be explained using an example illustrating the invention.

At the joint between the horizontal portion 1a and the inclined portion 1b of the handrail 1 (see Figures 1, 2, and 5), the handrail 1
The horizontal part 1a of the horizontal part 1a (hereinafter referred to as "kasagi") and the inclined part 1b (hereinafter referred to as "kasagi") have a horizontal part 2 (hereinafter referred to as "kasagi") and a horizontal part 1b (hereinafter referred to as "kasagi") which are connected by a first connector 4 and a second connector 5 (Fig. 5A). (see section).

The first connector 4 is attached to the end of the cap 2,
The second connector 5 is attached to the end of the cap 3.

The first connector 4 is formed from a fitting part 6, a collar part 7, an overhanging part 8, and protrusions 9, 9. Further, the first connector 4 is entirely integrally formed from a synthetic resin material or the like, and has some degree of elasticity.

The fitting portion 6 is formed hollow with a substantially rectangular cross section. The fitting portion 6 is fitted into the end of the cap 2 and is screwed to the cap 2 by mounting screws 13, 13.

The flange portion 7 is provided at the peripheral edge of the distal end of the fitting portion 6 so as to protrude continuously over the entire circumference of the fitting portion 6 so as to cover the end face of the cap 2.

The projecting portion 8 is provided protrudingly from the tip of the insertion portion 6 and is formed in a substantially groove-like cross section that opens directly below.

The upper surface of the projecting portion 8 is formed into a curved surface that bulges upward in an arc shape, and the left and right side portions are formed into vertical surfaces. Protrusions 9, 9 are formed approximately at the center of the tips of the left and right side surfaces. On the other hand, the second
The connector 5 includes a fitting part 10, a collar part 11, and a storage part 12.
It is formed from. Further, the second connector 5 is
Like the first connector, the entire connector is integrally formed from a synthetic resin material or the like, and has some degree of elasticity.

The fitting portion 10 is formed hollow with a substantially rectangular cross section. The fitting portion 10 is fitted into the end of the cap 3 and screwed to the cap 3 by mounting screws 13, 13.

The collar portion 11 has a cap 2 attached to the peripheral edge of the tip of the insertion portion 10.
It protrudes continuously around the entire circumference of the insertion part 10 so as to cover the end face of the insertion part 10.

In the housing portion 12, the insertion portion 10 is formed into a substantially rectangular hollow cross-sectional shape into which the overhanging portion 8 of the first connector 4 can be inserted loosely.

Arc-shaped guide grooves 14, 14 are formed in the left and right side walls 12a, 12a of the storage portion 12, in which the left and right protrusions 9, 9 of the first connector 4 can engage.

Furthermore, recesses 12b, 12b are formed at both left and right ends of the storage portion 12, with which the left and right side walls 8a, 8a of the overhanging portion 8 of the first connector 4 can engage.

In such a configuration, the overhanging part 8 of the first connector 4 is inserted into the storage part 12 of the second connector 5, and the left and right protrusions 9, 9 of the overhang part 8 are inserted into the storage part 1.
By engaging with the left and right arcuate guide grooves 14, 14 of 2, the first connecting tool 4 and the second connecting tool 5 are connected, and as a result, the cap 2 and the cap 3 are connected.

Further, the first connector 4 and the second connector 5 can freely rotate within the length range of the arcuate guide grooves 14, 14, and as a result, the caps 2 of the horizontal portion 1a of the handrail 1 and the caps 2 of the vertical portion 1b It is possible to freely adjust the angle with the Kasagi 3.

Note that numerals 15 and 15 in the figure are gap closing devices, which are attached for the purpose of closing the gap created below the connecting portion between the cap 2 and the cap 3.

3 and 4 show other embodiments of this invention, in which the shape of the first connector 4 and the shape of the second
The configuration is almost the same as the embodiment shown in FIGS. 1 and 2, except that the shapes of the arcuate guide grooves 14, 14 of the connector 5 are different. That is, the first connector 4
The side walls 8a, 8a are protruded in parallel from the tip of the fitting part 6, and the lower end surface thereof is formed in an arc shape, and the arc guide grooves 14, 14 of the second connector 5
is formed by bulging downward. This connecting device is used, for example, in section B in FIG.

(Effects of the device) This device has the following effects because it has the above configuration.

The overhanging part of the first connector is inserted into the storage part formed in the insertion part of the second connector, and the left and right protrusions formed in the overhang part are engaged with the arcuate guide grooves formed on the left and right side walls of the storage part. Because it is guided, there is no risk of damage or deformation even if force is applied from the side.
The connection strength is extremely high.

Furthermore, since the connecting parts between the connectors are not exposed, the appearance is also very good.
