Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hinge comprising a connecting member and an engaging member.

(Prior art) A hinge is generally used as a member that connects two plates, folds them to the required side, and opens them at 180 degrees. A pair of metal fittings equipped with means are pivotally supported by pins so that they can rotate freely.

(Problem that the invention aims to solve) However, conventional hinges do not allow the two plates to be connected at 180 degrees.
When opened, the hinge metal fittings are exposed, giving it an ungainly appearance.

This invention was made to solve the above problems, and the purpose of this invention is to prevent the metal fittings of the hinge from being exposed to the outside when the two plates are opened at 180 degrees. not have a good appearance,
Moreover, the purpose is to ensure that both plate materials are fixed flush.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a hinge in which two plates 1 and 2 can be folded by a connecting member 9 and engaging members 3 and 4. Both of the engaging members formed into a box shape with at least one side open in the vertical direction are attached to the backs of the both plate materials so as to abut each other in the vertical direction, and the connecting member is disposed across both the engaging members. A fixed pin pivotally supported at one end of this connecting member is fixed to one plate material, a sliding pin is pivotally supported at the other end of the connecting member, and a guide groove in which this sliding pin slides is fixed to one of the plates. It is formed on the side of the engagement member.

(Function) According to the above means, when the two plates are opened at 180°, the hinge metal fittings are not exposed to the outside, and both plates are fixed flush.

(Embodiment) A preferred embodiment of the present invention will be described below in detail based on the attached drawings.

The drawings show the case where the present invention is applied to a mirror plate. Figure 1 is a side sectional view showing two mirror plates folded, and Figure 2 is a side sectional view showing two mirror plates folded.
Figure 3 is a sectional view of the side showing the state unfolded at 180°; Figure 3 is a sectional view of the side showing the same fixed state;
This figure is a plan view showing a state in which the back plate of FIG. 3 is removed.

A mirror is fitted on each of the surfaces of two mirror plates 1 and 2, and the back surface 1 of both mirror surfaces 1a and 2a is
Box-shaped engaging members 3 and 4, which are open in the vertical direction, are attached to the ends of b and 2b facing each other. The engaging members 3, 4 are provided with side plates 5, 5,
It consists of 6, 6 and back plates 7, 8, which are in contact with each other in the vertical direction. A connecting member 9 is disposed within both the engaging members 3 and 4, and is made by winding both end portions of a plate shape to one side, respectively. A fixing pin 10 is rotatably inserted through one winding portion 9a of the connecting member 9, and both ends of the fixing pin 10 are fixed to both side plates 6, 6 of one of the engaging members 4. Further, a sliding pin 11 is rotatably inserted into the other winding portion 9b of the connecting member 9, and both ends of the sliding pin 11 are arranged in the longitudinal direction of both side plates 5, 5 of the other engaging member 3. It is capable of sliding freely within the provided guide groove 12. The guide groove 12 has a small diameter 12a on the side of the engagement member 3 facing the other engagement member 4, and a large diameter 12b on the other side.

On the other hand, a slide plate 14 equipped with a knob 13 is provided on the back surfaces 1b and 2b of the mirror plates 1 and 2 so as to be slidable up and down. When folded as shown in FIG. 1, the locking piece 15 provided on the slide plate 14
However, the entire slide plate 14 is secured to the rear surface 2 of the mirror plate 2 by being locked by a pin 16 provided at the end opposite to the end to which the fixing pin 10 is fixed in the engaging member 4.
It is housed in b.

Next, as shown in FIG. 2, this mirror plate 2 is
Expand 180° and then turn knob 13 as shown in Figure 3.
When the slide plate 14 is moved downward, the knob 13 is fixed at the upper part 4a of the engagement member 4, and the lower end of the slide plate 14 is fixed by a pin 17 provided in the engagement member 3. At the same time, since the slide plate 14 presses the winding portion 9b of the connecting member 9, the fixing claw 18 provided on the connecting member 9
is fitted into the hole 19 bored in the engaging member 3,
Both mirror plates 1 and 2 are fixed, and mirror plates 1a and 2
a will be flush.

Note that the lower end of the mirror plate 1 may be provided with legs, for example, to form a furniture-like configuration, or the mirror plate 1 may be fitted into a wall or the like to have a built-in structure.

(Effects of the invention) As detailed above, according to the invention, both the engaging members, which are formed in a box shape with at least one side open in the vertical direction on the backs of both plate materials, are brought into contact with each other in the vertical direction. Attachment, arranging the connecting member across both engaging members, fixing a fixing pin pivotally supported at one end of the connecting member to one plate material,
A sliding pin is pivotally supported at the other end of the connecting member, and a guide groove in which the sliding pin slides is formed on the side of the one engaging member, so that the hinge can be maintained even when the two plates are unfolded. Since the metal fittings are not exposed to the outside and the plate surface is flush, a good appearance can be obtained. Furthermore, when applied to a mirror plate, since the mirror surface is flush, it has the effect of projecting the same appearance as a single ordinary mirror plate.

[Brief explanation of the drawing]

The drawings show the case where the present invention is applied to a mirror plate. Figure 1 is a side cross-sectional view showing two mirror plates folded, and Figure 2 is a side sectional view showing two mirror plates folded.
Figure 3 is a sectional view of the side showing the expanded state at 180°; Figure 3 is a sectional view of the side showing the same fixed state;
The figure is a plan view showing a state in which the back plate of FIG. 3 is removed. In the drawings, 1 and 2 are mirror plates, 3 and 4 are engaging members, 9 is a connecting member, 10 is a fixing pin, 11 is a sliding pin, and 12 is a guide groove.
