[0001]
TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail connector used for attaching a handrail to a wall surface of a handrail or joining seams of a bar.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 2001-32491 describes an elbow-type handrail connector used for attaching a handrail to a wall surface of a bar or joining seams of the bar. FIG. 9 shows an example of a concrete example of this.
[0003]
In this connector, seats 51 and 52 are provided at both ends of a bent split tubular main body 50, which are fixed to a bar of a handrail and a wall surface with screws or the like, and outer portions of the peripheral wall of the main body 50 are seated at both ends. An opening is provided between the openings 52, and a cover 53 connected to the peripheral wall of the main body 50 is detachably attached to the opening.
[0004]
An insertion piece 54 extends from one end of the cover 53, and an engagement protrusion 56 is formed at the other end of a protrusion 55 protruding from the inner surface. An insertion hole 57 is provided in one seat 51 of the main body 50, and an elastic bar 59 is provided in the other seat 52 in a state of being supported by a pair of pedestals 58 and floating.
[0005]
In order to fix the cover 53 to the main body 50, the insertion piece 54 is inserted into the insertion hole 57, and the engagement projection 56 is pushed while the elastic rod 59 is bent, so that the engagement projection 56 is engaged with the elastic rod 59. Let it.
[0006]
The cover 53 is made of the same metal as the main body 50 in the case of a high-grade product, and is made of plastic in the case of a popular product.
[0007]
[Problems to be solved by the invention]
By the way, in the above-mentioned connecting device, it takes time and effort to attach the elastic rod 59 to the main body 50, and there is a problem that even if the cover 53 is made of plastic, the cost cannot be reduced much.
[0008]
Accordingly, an object of the present invention is to provide a handrail connector that has a simple structure and can be manufactured at low cost.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention inserts the insertion piece extended at one end of the cover into the insertion hole on one seat side, while bending the elastic plate extending inward from the other end of the cover, The cover is fixed to the main body by engaging the engaging projection at the tip with the dug portion on the other seat side.
[0010]
With this configuration, it is not necessary to attach another member such as an elastic bar to the main body, and the cover can be formed as an integrally molded product, thereby reducing the manufacturing cost.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0012]
As shown in FIGS. 1 and 2, this handrail connector is provided with seats 2 and 3 which are fixed to the bar material and the wall surface of the handrail with screws or the like at both ends of a bent split tubular main body 1, respectively. An outer portion of one peripheral wall is opened between the seats 2 and 3 at both ends, and a cover 4 connected to the peripheral wall of the main body 1 is removably mounted on the opening.
[0013]
An insertion piece 5 extends from one end of the cover 4, and an engagement projection 7 is formed at a tip of an elastic plate 6 extending inward from the other end of the cover 4. An insertion hole 8 is provided in one seat 2 of the main body 1, and a dug portion 9 is provided in the other seat 3. The main body 1 is made of metal, and the cover 4 is an integrally molded product of plastic.
[0014]
In order to fix the cover 4 to the main body 1, as shown in FIG. 3, the cover 4 is tilted, the insertion piece 5 is inserted into the insertion hole 8, and the cover 4 is turned around the insertion piece 5 to be elastic. As shown in FIG. 4, the engagement protrusion 7 is engaged with the dug portion 9 while bending the plate 6.
[0015]
Such a connecting device does not require attaching a separate member such as an elastic bar to the main body 1 as in the conventional example, and since the cover 4 is a plastic molded product, it can be manufactured at low cost and has excellent workability. Will be something.
[0016]
When the cover 4 is made of the same metal as the main body 1 to produce a sense of quality, as shown in FIGS. 5 to 7, the elastic plate 6 is attached to the cover 4 as a separate spring by caulking or the like. What should I do?
[0017]
As described above, even when a popular product and a high-end product are manufactured, the main body 1 can be used for both products, so that the number of types of components does not increase and the production and the management of components can be rationalized.
[0018]
By the way, in the above embodiment, the handrail bar is attached to the wall surface. However, the cover fixing structure according to the present invention includes a connecting device for joining the handrail bars, as shown in FIG. The present invention can also be applied to a connector for receiving a bar.
[0019]
【The invention's effect】
As described above, in the connector according to the present invention, the cover is fixed to the body by bending the elastic plate provided on the cover, engaging the engaging projection at the tip thereof with the dug portion of the seat. Therefore, there is no need to attach another member such as an elastic bar to the main body, and the manufacturing cost can be reduced.
