Description

[Detailed description of the invention] Industrial application field The present invention relates to a connection structure between a lattice and a lattice of a handrail, fence, etc. More specifically, it is possible to easily and firmly connect a lattice to a lattice with a single touch. Concerning the connection structure between the beam and the lattice.

Conventional Technology Conventionally, when connecting a railing or fence made of metal such as aluminum to a grid, fixing methods such as bolts or welding have been used, but these methods are extremely time-consuming and time-consuming. expensive and not efficient. For this reason, various methods have been proposed for connecting the lattice and the lattice through engagement.
There are very few connection structures between a lattice and a lattice that can reliably connect a lattice to a lattice with a single touch, have a simple structure, and can be manufactured easily and inexpensively.

Problems to be Solved by the Invention The present invention was devised in view of the above circumstances, and it is possible to easily and firmly connect the railings and lattices of handrails, fences, etc. with one touch, and the structure is simple. The purpose of the present invention is to provide a connection structure between a lattice and a lattice that can be manufactured easily and inexpensively.

Means for Solving the Problem That is, in order to achieve the above object, the present invention provides elastically deformable protruding engaging parts whose tips protrude laterally on the mutually opposing side walls of the lattice main body, and , on one side of the rod body, locking protrusions that protrude laterally from the tip to the rear end in a manner that corresponds to each of the protruding engagement portions and press these engagement portions are provided on the tip side. An engaging protrusion provided on the lattice body is provided in a protruding manner, and the lattice body is pushed toward the lattice body so that the protruding engaging part comes into contact with the locking protrusion of the lattice body, and the protruding engaging part is locked. The lattice body is pressed by the protrusion to be elastically deformed in the opposite direction to the protruding direction, and the lattice body is further pushed in to release the pressing force of the locking protrusion against the protruding engagement part, returning the protrusion engagement part to its original protruding state. The lattice is irremovably connected to the lattice by elastically restoring and locking the tip of the protruding engagement part to the shoulder of the locking protrusion.

Effect According to the present invention, when connecting the lattice and the lattice,
When the lattice body is pushed toward the lattice body so that its protruding engaging part comes into contact with the locking protrusion of the lattice body, the protruding locking part is pressed by the locking protrusion and becomes elastic in the opposite direction to the protruding direction. Since the lattice body is deformed, the lattice body can be pushed in smoothly, and when the protruding engaging part passes the locking protrusion position, the pressing force from the locking protrusion against the protruding engaging part is released, so that the protruding engaging part Since the tip of the lattice naturally elastically returns to its original state, the protruding engagement part is locked to the shoulder of the locking protrusion, and therefore, the lattice can be attached to the lattice simply by pushing the lattice body towards the lattice body. The lattice and the lattice can be connected with one touch without any effort. In addition, after the protruding engagement part is elastically restored, the protruding engagement part is not pressed, so that it is reliably engaged with the shoulder of the engagement protrusion and the engaged state is not released. Therefore, the connection between the lattice and the lattice is ensured and irremovable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First Embodiment Figures 1 to 3 show an embodiment of the present invention. In the figures, 1 is a rectangular cylindrical rod body 2 having a length extending along the axial direction at the center of one surface (lower surface in the figure) of the rod body 2. This is a rod made of metal such as aluminum and has a protruding plate 3. Notches 4 are formed in each of the elongated plates 3 at positions spaced apart from each other by a predetermined distance (positions where the grids should be connected). It is protruded from one side of the. At the tip of the engagement protrusion 5, locking protrusions 6, 6 that protrude toward both sides are integrally provided, and these locking protrusions 6, 6 extend from the tip to the rear end, respectively. The tapered walls 6a, 6a are formed so that the width becomes gradually wider toward the rear, and a shoulder portion 6 is provided behind the rear end of the locking protrusions 6, 6.
b, 6b.

Further, 7 is a lattice made of metal such as aluminum, and this lattice 7 has an octagonal cylindrical lattice main body 8 and a side wall that exists near one end in the axial direction of this lattice main body 8 and faces each other. It is composed of protruding engagement parts 10, 10 formed by providing substantially U-shaped cuts 9, 9, and bending and protruding the tips of the tongue pieces formed thereby, respectively, inwardly. These protruding engaging portions 10, 10 are each formed to be elastically deformable.

When connecting the lattice 7 to the above-mentioned rail 1,
Push one axial end of the lattice body 8 into the engagement protrusion 5 (in the direction of the arrow in the figure), and insert the protruding engagement parts 10, 10 of the lattice body 8 into the locking protrusions 6, 6 of the engagement protrusion 5. bring it into contact. When the lattice main body 8 is further pushed in from this state, the protruding engaging parts 10, 10 are elastically deformed by the pressing force from the locking protrusions 6, 6, and the protruding engaging parts 1
0 and 10 are elastically displaced outward, the lattice main body 8 engages the locking protrusions 6 and 10 of the engagement protrusion 5.
When the protruding engagement parts 10 and 10 pass through the protruding parts of the locking protrusions 6 and 6, the locking protrusions 6 and 6 can pass through the protruding parts 10 and 10. The pressing force is released, and as a result, the protruding engaging parts 10, 10 elastically return to their original state, that is, the state in which their tips protrude inward, and the engaging protrusions 5 are inserted into the lattice body 8. In the inserted state, the tips of the protruding engagement parts 10, 10 of the lattice main body 8 are locked to the shoulders 6b, 6b of the locking protrusions 6, 6, and the lattice 7 is connected and fixed to the lattice 1. .

In the embodiment described above, when pushing the lattice main body 8 into the engagement protrusion 5, since the tapered walls 6a, 6a are formed on the locking protrusions 6, 6, the pushing is performed very smoothly, and the pushing is performed very smoothly. After completion, the protruding engaging parts 10, 10 are elastically restored to their original state by the elastic restoring force of the protruding engaging parts 10, 10, and are locked and fixed to the locking protrusions 6, 6, so that the fixing No post-operation is required, and connections are made easily and reliably. Furthermore, since the engaging protrusion 5 is inserted into the lattice body 8 and the protruding engaging parts 10, 10 are also hidden within the lattice body 8, the connection between the lattice 1 and the lattice 7 can be performed in an attractive manner.

Second Embodiment FIGS. 4 and 5 show another embodiment of the present invention. In this embodiment, protrusions protruding outwardly from the mutually opposing side walls of the lattice main body 8 are provided. The protruding engaging parts 10, 10 are provided to lock the protruding engaging parts 10, 10 to the shoulder parts 6b, 6b of the locking protrusions 6, 6 of the engaging protrusions 5, 5 adjacent to each other, and A rectangular plate 11 located between the engaging protrusions 5 and 5 and protruding from one side of the lattice body 2 is inserted into the lattice body 8, and other configurations and effects are the same as those of the first embodiment. Since it is similar to the example, the same reference numerals are given to the same constituent parts, and the explanation thereof will be omitted.

In addition, in the above-mentioned embodiment, the width direction of the engagement protrusion 5 is aligned with the axial direction of the pole body 2, but as shown in FIG. Alternatively, locking protrusions 6 may be formed on all sides as shown in FIG. The protruding engaging portions 10 may be provided on all sides of the main body 8. Furthermore, the shapes of the lattice body 2 and the lattice body 8, the configurations of the engagement protrusions 5 and the locking protrusions 6, the configuration of the protruding engagement parts 10, etc. can be variously changed within the scope of the present invention.
