Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a universal hinge.

(Prior Art) A hinge is made up of a pair of members that function as a joint tool, and has a structure in which pins are joined together so that they can swing around a central axis. Therefore, the conventional hinge is used for joining an opening / closing portion and a member that is mounted in a folding manner, but the direction of opening / closing or folding is always constant.

(Technical problem) Therefore, even if a folding shelf is assembled using the hinge,
The folding direction of the panel is limited to one direction, and there is not much freedom, and there is no choice other than stretching or folding.

The object of the present invention is not only to connect a pair of members swingably around a central axis but also to pivot about an axis orthogonal to the central axis, which has a greater degree of freedom than an ordinary hinge. To provide.

(Technical Means) The purpose is to provide a pair of members 1 and 2 around a central axis a,
One of the members, which is pivotally joined to each other, is divided into two parts 11, 12 and is pivotally supported so as to be rotatable about an axis b orthogonal to the central axis a. Can be reached by different configurations.

(Example) Explaining with reference to the drawings, the pair of members 1 and 2 each have a pin joining means at each joining end, and the means is at the end of the other member 2 in the direction of the central axis a. Hinge pin 3 that extends,
It comprises a pin hole 4 provided at the end of one member at a position where it engages with the hinge pin 3. The tip end of each pin 3 has an inclined surface 5 with a narrow width in the direction of fitting into the pin hole 4, and the receiving side pin hole 4 has an inclined surface 6 with an open front end so that the pin 3 can be fitted easily and the swingability is improved. It does not change and does not easily come off, so it is highly effective.

The pin hole 4 is provided in one joint portion 11 of the two portions 11 and 12 constituting one member 1, which has an inverted gate shape as shown in each drawing and has bearing pieces 13 on both sides. , 13 to pin hole 4
And the bearing pieces 13, 13 are regulated by stopper surfaces 14, 14 provided on the pin base of the other member 2. A shaft hole 8 in the direction of the orthogonal axis b is formed in the center of the bottom of the joint portion 11, and a large diameter hole 15 is adjacent to the shaft hole 8 to form a substantially daruma-shaped hole. 15 to the bulge 16 of the support shaft 7
Is inserted.

A portion 12 having the support shaft 7 is a means for attaching to an object to be hinge-joined, and has two pieces of clamps 9 and 9 for holding the object. Similar clamps 9 ', 9'are also provided on the other member 2 and each clamp 9, 9,
Each of 9'and 9'has a small protrusion 17 on its inner surface for engaging with an object to enhance the fixing force. Reference symbol P in the drawing indicates a panel which is an object to be joined. The flexible hinge H configured as above is
It enables a snap-in assembly that can be assembled by simply fitting together all manufactured by synthetic resin molding.

(Operation) In the universal hinge H configured as described above, one member 1 is combined by fitting the support shaft 7 and the shaft hole 8 and then the pin holes 4 and 4 of the joint portion 11 are combined with the other member 2. Hinge pins 3, 3
Are assembled by mating and are therefore significantly easier to manufacture. Moreover, the support shaft 7 can be fitted into the shaft hole 8 through the large diameter hole 15, and the hinge pins 3 and 3 are guided and fitted into the pin holes 4 and 4 by the inclinations 5 and 6, whereby the assembling ease is further improved. Such a flexible hinge H has its clamp 9,
It is mounted by being inserted into the side portion of the panel p between 9, 9'and 9 ', and is assembled by using a necessary number as shown in FIG. 6, for example, and is used to form a required structure. be able to.

Since one of the assembled panels p, which is assembled by the free hinge H, can swing about the central axis a of the hinge and can rotate about the orthogonal axis b, it is shown in FIG. Then, when the panel P in the state shown by the solid line is rotated 90 degrees around the support shaft 7, the back wall is formed right above the lower panel, and from that state, it is swung 90 degrees forward around the hinge pin 3. Make a ceiling. Further, when the hinge pin 3 is swung 90 degrees forward from the state shown by the solid line in FIG. 6, a middle partition is formed.

(Effect) The swivel hinge of the present invention is not only capable of swinging the pair of members 1 and 2 around the central axis a to join an object, but also rotatable about the orthogonal axis b of the central axis. As a result, the position of the object can be freely changed, so that it has a great degree of freedom as compared with the conventional hinge, and since the pair of members 1 and 2 can be snap-in assembled, the manufacturability is remarkably good. There is an effect that the practicality and utility value of this type of hinge can be improved.
