Description

[Detailed description of the invention] The present invention relates to a hinge.

Conventional hinges are often made of metal, and most hinges generally consist of a pair of a male member having a pin and a female member receiving the pin.

The structure of such hinges is relatively complex, as they are assembled from male and female members, and the operation is heavy and tends to squeak. If it had the property of deforming even slightly due to temperature changes, it would not be suitable for use in such items.

For example, they could not be used reliably as hinges for doors, etc. of furniture installed in various vehicles that are forced to drive under various conditions.

An object of the present invention is to eliminate the drawbacks of such conventional hinges.

As a measure for this purpose, in the present invention, plastic is selected as the molding material, and two identical components are assembled into a hinge to form a hinge. is formed with a through hole on the other side with an outwardly projecting pin, and the two hinge components are turned in opposite directions and each snap-engages the other pin into its own through hole (described below). ), etc., to assemble the hinge.

The first advantage of doing this is that it is very economical to manufacture because the same components for assembling the hinge can be used.

Second, since the hinge components can be molded in one piece, there is no need for the complicated assembly process required in conventional hinge manufacturing, such as inserting a pin into only one of the hinge components. There is also.

In the past, plastics could be selected as the molding material, so even if the hinged article were to be deformed, the elasticity of the plastic itself would allow it to absorb or follow the deformation to a considerable extent.

This is especially true when placed in an environment with significant temperature changes (
For example, when used in the doors of articles such as various vehicles, etc., the elasticity of each pin of both hinge components allows it to perform an effective function.

An embodiment of the hinge of the present invention will be described below in detail with reference to the accompanying drawings, but it is needless to say that the invention is not limited to what is shown in the drawings.

First, FIGS. 1 to 3 show the hinge components that constitute the hinge of this embodiment as a set of two, and the structure will be explained as follows.

In this case, ears 2 and 3 are provided at both ends of the rectangular plate-shaped base 1 in the longitudinal direction so as to stand perpendicularly to the base, and one ear 2 (on the left in the drawing) has a through hole 4. A pin 5 protrudes from the outer surface of the other ear 3.

The tip of the pin 5 has a head 6 with a thicker diameter, and the pin 5 is connected from the tip of the head 6 to provide flexibility near the head.
A cut 7 of an appropriate depth is inserted by 1 in the area.

The diameter of the through hole 4 is approximately the same as the diameter of the pin 5. In other words, if you take out the pin 5 and insert it into the through hole, the diameter of the pin 5 will fit exactly 1.
It is preferable to set it to such an extent that it is possible to do so so that there is no looseness in assembly when the same hinge component is used as a hinge as described later.

Note that the central axis of the through hole 4 and that of the pin 5 must be aligned so that they are coaxial.

Countersink holes 8 and 9 are inserted through the base 1 assuming that screws will be used to fix the hinge to the beloved item. Even if it is provided, its shape and position may be determined according to the actual situation.

The hinge components having the above configuration are assembled as shown in FIG. 4, and in this figure, the same hinge components are shown as A and B, respectively, in a state facing each other.

For example, in order to use a hinge that controls the opening and closing functions of doors of various types of furniture, either one of the hinge components may be used, but one hinge component should be placed on the door side and the other on the furniture main body. Fix it so that

There is no problem in interpreting Figure 4 as a diagram excluding objects that are hinged, such as doors, in such a state.

After doing this, each pin is pushed into the other's through hole.

The head of each pin is bent so as to pinch the cut and come together, and then it enters the hole, and when the head comes out of the ear that defines the hole, it restores itself in a non-returning manner. Assembly is complete.

After the snap engagement has been made in this manner, the two lateral parts will not become disengaged unless the head is intentionally pushed back into the through hole.

It is desirable that the distance between the edge of the ear side of the head and the surface of the ear where the duck meat is made is just enough to accommodate the ear with the through hole therebetween, so that there is no wobbling after assembly.

Incidentally, the degree of cutting of the head should be determined based on the actual situation.

Although the present invention has been described in detail above, it goes without saying that the present invention is not limited to the above-mentioned embodiments, and the applicant is expected to make various modifications as long as they conform to the latent technical idea.

[Brief explanation of the drawing]

FIG. 1 is a plan view of a component of an embodiment of the hinge of the present invention;
Figure 2 is a sectional view taken along the line 2-2 in Figure 1, Figure 3 is an end view of the hinge component shown in Figure 1 as seen from the through hole side, and Figure 4 is the same as shown in Figures 1 to 3. FIG. 2 is an explanatory diagram perspectively showing a pattern of hinge assembly using two identical hinge components. In the figure, 1 is the base of the hinge component, 2 and 3 are ears, 4 is a through hole, and 5 is a pin.

Claims (1)

[Scope of Claims] 1. Consisting of two hinge components each having ears at both ends of the base, one ear having a through hole and the other ear having a pin protruding outward, A plastic hinge characterized by its own pin snapping into a through hole. 2. Claim 1, characterized in that the tip of the pin is provided with a head that is thicker than the diameter of the pin and has a cut in order to produce flexibility when the pin is bent.
