[Problems to be solved by the device]

 However, in the conventional hinge device, all parts, including the fixed base plate, both movable base plates, and stopper links, are separately formed from metal materials, and then the parts are individually assembled. Due to the adoption of the configuration, the number of parts increases unnecessarily, resulting in an increase in weight and cost, but in particular, there is a problem that the assembling work becomes difficult, and the contact sliding Since all moving parts are metal-touch, there was a risk of rust and abnormal noise. Needless to say, even if the auxiliary movable base plate is omitted, the assembly workability still has the same problem. Therefore, the present invention aims to provide a novel hinge device that can effectively solve the problems of the conventional hinge device.

[0006]

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. The hinge device according to the first embodiment is different from the conventional device in that a hinge body 1 integrally molded of synthetic resin is used, and a console box or the like is used. The feature is that the lid is attached to the box body side so that it can be opened and closed. More specifically, the hinge main body 1 made of synthetic resin has a fixed base plate 2 fixed to the box main body side and a main movable base plate fixed to the lid side as shown in FIGS. 1 and 2. 3 and a folded back base plate 4 which is folded back onto the upper surface of the fixed base plate 2 and has a main movable base plate 3 on the one end edge side of the fixed base plate 2 located in the middle of the hinge body 1 as a first thin hinge piece. 5, the return base plate 4 is connected to the other end of the fixed base plate 2 via the second thin hinge piece 6 so as to be returnable.

The fixed base plate 2 is formed into a rectangular shape having a desired size, and a pair of block parts 7 are integrally formed on both sides of the upper surface side of the fixed base plate 2, and a plurality of guide holes 8 and screws are formed in the width direction part thereof. Each of the holes 9 is formed, and the main movable base plate 3 is formed in a substantially L-shaped cross section, and slides the working end portions 10a of the double torsion springs 10 for assisting the opening movement of the lid on both sides of the upper surface side. A pair of receiving surfaces 11 are formed in contact with each other, and a plurality of screw holes 12 are formed on the free end side thereof. The folded base plate 4 is formed in a size that can be overlapped with the fixed base plate 2, and the lower surface side thereof is formed. A pair of bearing portions 14 for supporting the mounting shaft 13 of the double torsion spring 10 are integrally formed on both sides, and a plurality of locate pins 15 inserted into the guide holes 8 are integrally formed at the upper surface side portion thereof. Success In addition, the screw holes 16 that match the screw holes 9 of the fixed base plate 2 are also formed.

Under the first embodiment, as shown in the figure, with respect to the receiving surface 11 of the main movable base plate 3, an inclined corner portion 11a is positively provided at a portion of each receiving surface 11 near the free end edge. The action end portion 10a of the double torsion spring 10 has a clear click feeling while the action end portion 10a of the double torsion spring 10 passes through the inclination angle portion 11a, and the action end portion 10a is inclined when the lid is closed and locked. The lock means is configured so that an unreasonable load is not applied by being slidably contacted with the upper portion of the corner portion 11a, but the present invention is not limited to this, and other concavo-convex shapes and the like are provided on each receiving surface. It is also possible to give it a desired click feeling at an arbitrary position from the fully opened to the fully closed of the lid by giving it to 11 arbitrary places.

Therefore, when the lid is openably and closably attached to the box body side using the hinge body 1 of the first embodiment, first, both end portions of the shaft 13 having the double torsion spring 10 mounted thereon are After being fitted and supported by the bearings 14 of the folded base plate 4, the second thin hinge piece 6 is deformed and the locating pins 15 are brought into the corresponding guide holes 8 of the fixed base plate 2 while When the folded base plate 4 is folded back toward the upper surface of the fixed base plate 2, the folded base plate 4 is positioned and superposed on the fixed base plate 2 as shown in FIG. Each block 7 is fitted to the outside of the corresponding bearing 14 of the folded base plate 4.

Therefore, under the first embodiment, the shaft from the bearing portion 14 can be obtained by simply superposing the folded base plate 4 on the fixed base plate 2 without using the conventional E ring, snap ring or the like. Since it is possible to automatically prevent the 13 from falling off and rattling, not only the number of parts is reduced, but also the work of assembling the shaft 13 and the temporary assembly of the hinge body 1 itself can be performed with one touch. It can be expected that the improvement of sex will be greatly expected.

Therefore, after obtaining the temporarily assembled state of the hinge body 1, as shown in FIG. 4, the folded base plate 4 and the fixed base plate 2 in the overlapping state are utilized by their own screw holes 9 and 16. Then, the box body B is fixed at a predetermined position on the opening edge with a screw 22, and the flange La provided inside the lid L is fixed to the main movable base plate 3 by using the screw hole 12 with a screw 22. In this case, the lid L is attached to the box body B side so as to be openable and closable. In the figure, 20 is a stopper arm that controls the fully open position of the lid L.

When fixing the fixed base plate 2 obtained by overlapping the folded base plate 4, the long locating pin 15 inserted into the guide hole 8 of the fixed base plate 2 is moved downward from each of the guide holes 8. In the first embodiment, as shown in FIG. 5, a hole for guiding the tip of the long locating pin 15 is previously inserted into the fixed portion side of the box body B in the first embodiment. 21 is formed, and the locate pin 15 is also used as the positioning means of the fixed base plate 2 with respect to the box body B 1. Therefore, in the first embodiment, the hinge body 1 itself in the temporarily assembled state can be easily fixed by using the locate pin 15 and the hole 21 at a predetermined position on the box body B. This also makes it possible to greatly improve the assembly workability from this point as well. Further, since the folded base plate 4 superposed on the fixed base plate 2 is fastened together with the box body B through the common screw 22 in a superposed state, for example, the folded base plate 4 is doubled. Even if the reaction force of the torsion spring 10 is received, there is no fear of inadvertently floating and rattling, and the shaft 13 is also entirely reinforced, so there is no worry of warping inadvertently.

Then, in actual use, when closing the opening of the box body B, when the free end side of the lid L is rotated in the closing direction against the spring pressure of the double torsion spring 10, double torsion occurs. Since the working end portion 10a of the spring 10 slides on the receiving surface 11 of the main movable base plate 3 to allow the lid L to rotate, the latter is not specifically shown, but is the same as the conventional one. If the lid L is locked in the closed position by a known locking means, the closed state of the lid L can be easily obtained as shown in FIG. In addition, at the time of such an operation, the presence of the inclined corner portion 11a of the receiving surface 11 provides a clear click feeling, and each working end portion 10a of the double torsion spring 10 slides above the inclined corner portion 11a. Since they come into contact with each other, there is no concern that the locking means will be overloaded. Furthermore, as shown in the figure, the hinge center of the first thin hinge piece 5 and the spring center of the double torsion spring 10 are offset from each other, so that the distance from the working end 10a of the double torsion spring 10 to the hinge center is increased. If the lid L is adjusted according to the opening / closing angle, it is possible to generate a certain appropriate torque for the opening / closing operation, so that a light and smooth operation is guaranteed.

On the contrary, when opening the opening of the box body B, if the locked state of the lid L is released, this time, the lid L is kept until the stopper arm 20 is regulated. Since the double torsion spring 10 is rotated by receiving the spring pressure, the lid L is securely held in its fully opened position as shown in FIG. In this fully opened state, each working end portion 10a of the double torsion spring 10 comes into sliding contact with a lower portion of the inclined corner portion 11a provided on the receiving surface 11.

Next, a hinge device according to the second embodiment will be described. The hinge device according to the second embodiment is intended for a lid L having a tray for an inner lid on the premise of the configuration of the first embodiment as it is. Was developed as. Therefore, in the second embodiment, as shown in FIG. 8, an auxiliary movable base plate 17 for fixing the tray for the inner lid is provided on the free edge side of the folded base plate 4 with the third thin hinge piece 18. The auxiliary movable base plate 17 can be housed in a recess 3a defined between the receiving surfaces 11 of the main movable base plate 3 in a cross-section substantially L. It is formed into a character-like size, and a screw hole 19 is formed on the free end side.

Therefore, also in the second embodiment, when the folded base plate 4 is folded back to the fixed base plate 2 side through the second thin hinge piece 6, the folded base plate 4 is placed on the upper surface of the fixed base plate 2. In this state, as shown in FIG. 9, the first thin hinge piece 5 that rotatably connects the main movable base plate 3 and the auxiliary movable base plate 17 are arranged. Since the third thin hinge piece 18 that is rotatably connected is aligned on the same line, a double hinge mechanism having the same hinge center can be easily provided.

Therefore, after that, although not specifically shown, the folded base plate 4 and the fixed base plate 2 in the overlapped state are screwed at predetermined positions on the opening edge of the box body B as in the first embodiment. 2 and the main movable base plate 3 is fixed to the inside of the lid L with a flange portion La by a screw 22. At the same time, the flange portion Ta of the inner lid tray T is fixed with a screw hole 19. If the screws 22 are used for fixing, the inner lid tray T can be attached to the box body B so as to be openable and closable, in addition to the effects of the first embodiment described above. Although a specific configuration relating to the inner lid tray T itself is not shown, at least a structure that is opened together with the lid L and a structure that can be opened and closed independently of the lid L are provided together. .

[Effect of device]

 As described above, the present invention is characterized in that the members / parts necessary for the hinge device are incorporated into the hinge body side integrally molded of synthetic resin, and each member / part is made to act organically. Compared with the conventional one, the number of independent parts has been drastically reduced, and the weight and cost can be effectively reduced, and the assembling work can be greatly simplified. Also, since the hinge body is made of synthetic resin, the contact sliding part does not have a metal touch, so there is no need to worry about rust or noise. Moreover, according to the present invention, it is possible to automatically prevent the shaft from coming off from the bearing portion and rattling by simply folding the folded base plate toward the upper surface of the fixed base plate. Not only is it possible to reduce the number of parts, but there is an advantage that the work of assembling the shaft and the temporary assembly of the hinge itself can be done with one touch. The locate pin formed on the folded base plate side can be used not only as a positioning means for the fixed base plate of the folded base plate but also as a positioning means for the hinge body itself with respect to the box body. By simplifying the work and adjusting the distance from the working end of the opening assisting spring to the hinge center according to the opening / closing angle of the lid, it is possible to generate a certain appropriate torque for the opening / closing operation. Therefore, a light and smooth operation is always guaranteed.

Further, by providing the receiving surface of the movable base plate with a form in which the sliding contact state with the working end of the opening assisting spring is changed, a desired click position can be obtained at any position from the fully opened to the fully closed of the lid. While the lid feels tight and the lid is prevented from being unduly loaded when the lid is closed and locked, the auxiliary movable base plate that secures the inner lid tray is hinged to the free edge of the folded base plate. The hinge body of the double-hinge mechanism can be easily provided by rotatably connecting the pieces via the piece.
