Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hinge capable of opening and closing a lid and a bottom.

[0002]

[Prior art]

 Conventionally, in this type of hinge, an axis is passed through the center of the coil spring and one end of the coil spring is brought into contact with the lid, and the other end is brought into contact with the bottom so that the coil spring acts in the direction in which the lid and the bottom open. At this time, the coil spring is set on the end surface of the lid and the end surface of the bottom. Therefore, when assembling such a hinge, the lid, the bottom, and the coil spring are separated, and even if the shaft is inserted into the coil spring and this shaft is fitted or fixed to the bottom or the lid, the lid or the bottom is not removed. Since it is not attached, the coil spring is an obstacle during the assembly process and is not easy to handle, and the coil spring cannot be fixed with one component. In addition, this type of hinge has a result of spoiling the appearance because the coil spring is exposed on the outer surface. Furthermore, if the appearance is to be adjusted, it will be an obstacle during assembly, and one part will be required. Further, when such a coil spring is attached, a method of closing the lid is required. This method has a lock mechanism on the front of the lid and bottom, but it is subject to extra space and design restrictions on the appearance. Therefore, the hinge part provided with the lock mechanism is provided.

[0003]

[Problems to be solved by the device]

 As mentioned above, the purpose of the conventional improvement is that the coil spring is difficult to handle at the time of assembly, it is impossible to fix the coil spring with one part, the coil spring is exposed to the outside, and an extra space is provided for the mechanism to lock the lid, etc. Is in the point of becoming large. Therefore, the assembly of the coil spring is facilitated by the tubular body with the groove that covers the coil spring (attachment), the coil spring is fixed by one component, and the coil spring is not exposed in appearance and has the lock mechanism. It provides a hinge.

[0004]

[Means for solving problems]

 In a hinge provided with a lid, a bottom and a coil spring so that the lid 10 and the bottom 9 can be opened and closed, a coil spring 5a attached to the opening direction of the lid 10 and the bottom 9 and a coil spring 5b attached to the opening direction of the lid 10 and the bottom 9. The hollow cylindrical bodies 1a and 1b are covered with a semicircular groove 3 at one end of the hollow cylindrical body 1 in the direction perpendicular to the axis and at the other end of the hollow cylindrical body 1 with respect to the axis. On the other hand, an end face of the hollow cylindrical body 1 in which a long circular groove 4 longer than the semicircular groove 3 is provided in the vertical direction, and the semicircular groove 3 and the long circular groove 4 respectively have the semicircular groove 3 at one end thereof The semicircular groove 3 is communicated with the thrust groove 2 extending to the longer circumferential groove 4, and the other end of the semicircular groove 3 is provided with a thrust recess 8 parallel to the axis line. The thrust groove opening end 11b of the hollow cylindrical body 1b is provided. The hinge is characterized in that a pressing member 20 that fits with the coil spring 5b is provided on the side.

[0005]

[Action]

 Both ends of the coil spring 5 are inserted into the thrust groove 2, and the coil spring 5 is guided and inserted into the hollow cylindrical body 1. Next, pushing the end face of the coil spring 5 on the opening side of the thrust groove 2 along the axis guides the short support end 7 to the semicircular groove 3, and in this state, when a turning force is applied to the long support end 6, the hollow cylindrical body is formed. When the coil spring 5 rotates in 1 and the short support end 7 moves to the position of the thrust recess 8, it rotates while maintaining the force pressed along the initial axis line, so this thrust force reacts to thrust. The short support end 7 is fixed by being guided to the recess 8. Then, the coil springs 5a and 5b are set. Next, the long support end 6 is brought into contact with the fixing portion 16 of the lid 10, and a coil spring 5a is attached in a direction to open the lid 10 and the bottom 9. The coil spring 5b is fitted to a pressing member 20 that is swingably provided to the left and right through the center of the holder 21, and is attached in a direction to close the lid 10. Here, since the coil spring 5b is normally provided with a stronger force than the coil spring 5a in the direction to close the lid 10, in order to open the lid 10, the pressing member 20 is pushed and fixedly supported in the thrust recess 8. The short support end 7 is guided to the semicircular groove 3. Then, since the coil spring 5b is twisted and acts in the direction of closing the lid 10, if the coil spring 5b is guided to the semicircular groove 3b, the short support end 7b moves in the semicircular groove 3b in the thrust groove direction by the reaction. Let

Then, the force of the coil spring 5b acting in the direction of closing the lid 10 is released, and the force of opening the lid 10 of the coil panel 5a acts to open the lid 10. Since the short support end 7b of the coil spring 5b is not fixedly supported, the coil spring 5b rotates in the hollow cylindrical body 1b when the lid 10 is opened, and the free long support end 6b and the short support end 7b are freely thrust. Induced by b. Since the coil spring 5 is in a state of being compressed in the direction of the axis L by the semicircular groove 3 and the elliptical groove 4, the short support end 7b moves toward the thrust groove opening 11 at the position of the thrust groove. Be induced. Thus, the lid 10 remains open. Next, when closing the lid 10, the pressing member 20 is compressed again in the direction of the axis L, and the short support end 7b is guided from the thrust groove 2b to the semicircular groove 3b to cover the inside of the hollow cylindrical body 1b. Since the short support end 7b is fitted to the pressing member 20, the short support end 7b is rotated in the same direction as the closing direction of the pressing member 20, and the short support end 7b is formed in the thrust recess 8 while twisting the coil spring 5b. Guide and fix.

【Example】

 Next, about the embodiment of the present invention, FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 6, FIG. 7, FIG. This will be described in detail with reference to FIGS. 11, 12, 13, and 14. Reference numeral 1 denotes a hollow cylindrical body, and the hollow cylindrical body 1 is provided at two positions on one side surface of the bottom 9. The hollow cylindrical body 1a has the thrust groove 2a on the front side, and the hollow cylindrical body 1b has the thrust groove 2b on the rear side. The hollow cylindrical body 1 is provided with a semicircular groove 3 and an elliptic groove 4 perpendicular to the center line in the vicinity of both ends. The semicircular groove 3 is provided in the thrust groove opening 11, one end of the semicircular groove 3 communicates with the thrust groove 2, and the other end is a closed end 12 with respect to the center line. A thrust recess 8 is provided in the normal direction. Next, the oblong groove 4 communicates with one end of the oblong groove 4 and the thrust groove 2 at a thrust groove closing portion 13, and the other end of the oblong groove 4 becomes a closed end 18. ing. Here, the angle θ from the thrust groove 2 with respect to the semicircular groove 3 is 90 ° ≦ θ ≦ 270 °.

With respect to the elliptical groove 4, the angle β from the thrust groove 2 is 180 ° ≦ β <360 °. Such hollow cylindrical bodies 1a and 1b have the connecting portion 14 disposed therebetween. As described above, the hollow cylindrical body 1b is provided with the coil spring 5b therein, and the short support end 7b side of the coil spring 5b and the pressing member 20 are press-fitted to each other, and the screw portion and screw provided in the thrust groove opening 11b. The pressing member 20 and the coil spring 5b are set by the fitting holder 21. Reference numeral 5 denotes a coil spring, which has a long support end 6 and a short support end 7 at seat portions at both ends. The coil springs 5a and 5b are provided inside the hollow cylindrical bodies 1a and 1b. The long support end 6 and the short support end 7 are on the same plane parallel to the center line. Reference numeral 10 denotes a lid, which is provided with a connecting portion 14 on one side surface, and further provided with a convex portion 15 on the connecting portion 14 so as to be rotatably fitted in the hollow hole of the hollow cylindrical body 1. In particular, the hollow cylindrical body 1 may be provided on either the bottom 9 or the lid 10. The connecting portion 14 is provided on the side facing the hollow cylindrical body 1.

In the assembling method, first, a coil spring 5 having a long supporting end 6 and a short supporting end 7 provided on the same plane parallel to the center line is inserted into the hollow cylindrical body 1. (The hollow cylindrical body 1a is taken as an example.) At this time, the long support end 6 is aligned with the position of the thrust groove 2 and slid in the axial direction. Then, the long support end 6 comes into contact with the thrust groove closing portion 13, and the short support end 7 is located at the front position in the axial direction of the semicircular groove 3. (FIG. 4, FIG. 5, FIG. 6) Next, when the short support end 7 of the coil spring 5 is pressed from the direction of the thrust groove opening 11, the short support end 7 is positioned at the position of the semicircular groove 3. When a rotational force is applied to the long support end 6 in this state, the short support end 7 is guided in the semicircular groove 3 while retaining the elastic force. (FIGS. 7, 8 and 9) Thus, when the short support end 7 is located at the position of the thrust recess 8, the short support end 7 is guided and fixed in the thrust recess 8 by the elastic force. . (FIG. 10, FIG. 11, FIG. 12) As described above, although the coil spring 5 is additionally provided, the state of FIG. 10 is a state in which no torsion is working. Further, since the pressing member 20 is press-fitted and fitted, the coil spring 5b moves together with the pressing member 20 during the assembling.

Next, a pair of convex portions 15 provided on both side surfaces of the connecting portion 14 provided on one side surface of the lid 10 are rotatably fitted into the hollow holes 17 of the hollow cylindrical body 1. The long supporting ends 6 are fixedly contacted with the inner surfaces of a pair of fixing portions 16 provided near the connecting portion 14. Then, when such a hinge is used, when the lid 10 and the bottom 9 are closed, a force acts in the opening direction and the coil spring 5a is twisted. Further, in order to keep the lid 10 closed, the coil spring 5b is set so as to act in the direction of closing the lid 10 together with the pressing member 20, and the twisting force of the coil spring 5a becomes 5a <5b. Therefore, since the long supporting end 6b and the mounting portion of the lid 10 come into contact with each other, the lid 10 is closed. Here, the locking mechanism only needs to be able to be held with the lid 10 and the bottom 9 closed, and the mechanism is not particularly limited. These hinges are effective for cosmetic-oriented containers, audio cases, and other containers that emphasize appearance. Further, when conventionally handled as a work-in-process product, the lid 10 and the bottom 9 are provided, and therefore it is difficult to handle in a state where the lid 10 and the panel member and the bottom and the spring member are assembled. However, in the case of the present invention, since the coil spring 5 can be fixed by the hollow cylindrical body 1, it becomes easy to handle when used as a container.

[0011]

【effect】

 With the above configuration, the following effects can be obtained. Since the coil spring 5 is arranged and fixed in the hollow cylindrical body 1, the coil spring 5 is not exposed in appearance. Since the coil spring 5 is fixed in the hollow cylindrical body 1, it is easy to handle as a work-in-process and easy to assemble. Since the thrust groove 2, the semicircular groove 3, the oblong groove 4, and the thrust recess 8 are provided in the hollow cylindrical body 1, the coil spring 5 can be fixed by one component. Since the coil springs 5a and 5b act on the lid 10 in different directions, the lid 10 can be freely opened and closed, and the lock mechanism can be incorporated into the hinge, so that no extra space is required.
