The surface of the connecting arm facing the pressing part having a slope provided at the part is an inclined surface that engages with the slope of the pressing part, and the member having the connecting arm is arranged at the middle part of the connecting arm in the opposite direction. It is characterized in that it is divided into individual parts and joined by a joining means.

In this hinge, a compression spring and a movable body are inserted into a pipe-shaped connecting part, and the connecting arms of each divided attachment body are stacked on both ends of the connecting part, and a support shaft provided on one of them is attached. Insert it into the other shaft insertion part, and engage the slope of the connecting arm with the pressurizing part of the movable body. Then, the divided attachment bodies are connected by a connecting means.

To explain the embodiment of the hinge of the present invention with reference to the drawings, 1 is a support with a U-shaped cross section for supporting the lid, and a pipe-shaped inner peripheral cross section with a circular cross section is attached to the outer surface of one of the opposing walls, and one end is closed. The connecting portion 2 is integrally provided with its axis parallel to the leading edge of the opposing wall of the support 1. The support 1 can also be a single plate. Reference numeral 3 denotes a support shaft protruding from the outer surface of the closing wall at one end of the connecting part 2; 4, a groove provided in the inner surface of the connecting part 2 in the axial direction thereof; and 5, a support shaft inserted into the closed end side of the connecting part 2. A compression coil spring is inserted into the side of the movable body 6, and the movable body 6 has a size and shape that allows it to move in the axial direction within the connecting portion 2, and has a locking member protruding from its outer surface. The mating piece 7 is inserted into the groove 4 so that it cannot rotate in the circumferential direction of the connecting part 2. A pressurizing part 8 is formed at an end of the movable body 6 opposite to the spring 5. The pressing part 8 has a surface inclined with respect to the axis of the connecting part 2. Compression springs 5 other than coils can also be used.

9 is a plate-shaped mounting body that can be attached to a box etc.
It has a connecting arm 10 protruding from both ends thereof,
The support shaft 3 is inserted into the shaft hole 11 made of a recess provided on the inner surface of one of the connecting arms 10A, and the support shaft 12 protruding from the inner surface of the other connecting arm 10B is inserted into the open end of the connecting portion 2. The mounting body 9 and the support body 1 are pivotally attached to each other. The tip end surface of the support shaft 12 is made to be sloped and is joined to the pressurizing part 8 of the movable body 6. The shaft hole 11 can also be a through hole.

The mounting body 9 is divided into two parts at the middle part of the connecting arms 10, 10 in the opposite direction. After being inserted into the interior, the divided attachment bodies 9A and 9B are joined together by a holder 13. The holder 13 in this example has groove-shaped holding parts 14 on three sides of a plate that is approximately the same size as the mounting bodies 9A and 9B, and the mounting bodies 9A and 9B are inserted into each holding part 14 and integrated. is combined with The support body 1, the mounting body 9, and the moving body 6 are made of synthetic resin or metal.

15 is the angle between the support 1 and the mounting body 9, that is,
Connecting arm 10 is used to determine the opening angle of the lid.
This is a rod-shaped stopper that protrudes from the inner surface of A at a position away from the shaft hole 11, and is inserted into an elongated hole 16 provided in an arcuate shape on the end surface of the connecting portion 2 facing the stopper 15. stoppa 15
As shown in FIG. Let it come out. Note that it is also possible to separate the stopper 15 from the support shaft 3 and the elongated hole 16 from the shaft hole 11. In addition, by providing protrusions that contact each other on both the outer circumferential surface of the connecting portion 2 and the mounting body 9 facing it, and by joining these to each other, it is also possible to regulate the opening angle of the lid, and the position where the stopper 15 is provided. can be selected arbitrarily. If you do not need to regulate the opening angle of the lid,
It is also possible to omit the stopper 15.

The support shaft 3 can also be provided on the connecting arm 10A and inserted into the shaft hole 11 provided at the end of the connecting part 2, as shown in FIG.

It is also possible to provide the support shaft 12 in the shape of a pipe at the end of the connecting portion 2 as shown in FIG. 6, and to insert it into a shaft insertion portion consisting of a recess provided in the connecting arm 10B. In this example, a sloped surface that engages with the pressure section 8 of the movable body 6 is provided at the center of the shaft insertion section formed of the recess provided in the connecting arm 10B.

The movable body 6 cannot rotate within the connecting portion 2 and
A concave groove 4 is provided in the connecting part 2, and an engaging piece 7 provided as a protrusion in the axial direction on the inner surface of the connecting part 2 is engaged with the concave groove 4. is also possible. Further, as shown in FIG. 9, the inner peripheral cross section of the connecting portion 2 may be square, and the cross section of the movable body 6 may have the same shape so as to be non-rotatable but slidable. Even if the inner circumferential cross section of the connecting portion 2 is square, there is no problem in inserting the support shaft 12.

The reason why the pressing part 8 of the movable body 6 is made to be a slope is due to the rotation of the connecting part 2, and when the movable body 6 is rotated together with it, it is pushed by the fixed support shaft 12 and moves. Since the purpose is to slide the body 6, the shape of the slope of the pressurizing part 8 is arbitrary, as shown in FIG.
A recess with a U-shaped cross section is formed in the pressurizing part 8, and the opposing surfaces thereof are sloped. Even if the tip of the support shaft 12 is shaped to fit inside the pressurizing section 8, the movable body 6
The purpose of moving can be reached.
In FIG. 8, the radial portions of the movable body 6 are sloped in opposite directions, and the ends of the support shafts 12 are also shaped in the same manner and mesh with each other.

The means for connecting the two divided attachment bodies 9A and 9B is optional, and as shown in FIG.
It is also possible to provide grooves 17 that communicate with each other and have bent ends, and insert the plate-shaped holder 13 into the grooves 17 to connect the grooves. In FIG. 11, the mounting body 9A and the mounting body 9B are large enough to be overlapped with each other, and the mounting body 9B is fitted and fixed in a recess 18 provided in a portion overlapping with the mounting body 9B. In FIG. 12, mounting bodies 9A and 9B are provided with mutually interlocking stepped portions on opposing sides, and a pin protruding from one of the stepped portions is inserted into a hole provided on the other and coupled. As shown in FIG. 13, it is also possible to connect the mounting bodies 9A and 9B with a caulking pin or the like passing through them. 19 is a mounting hole provided in the mounting body 9, and the holder 1
3 is also provided.

This hinge, for example, as shown in FIG.
The mounting body 9 is inserted into the insertion part 21 provided on the back side of the box body 20 and attached to the box body 20, and the back wall of the lid 22 is inserted into the support body 1 having a concave cross section.
Attach it to support 1. When the lid 22 is opened, the pressurizing part 8 of the movable body 6 is engaged with the tip of the support shaft 12, and the spring 5 applies appropriate pressure to the movable body 6, as shown in FIGS. Because I'm under pressure,
Keep the lid open. The mounting body 9 may be fixed to the mounting hole 19 using wood screws or the like.

When closing the lid, push it down and the movable body 6 rotates together with the support 1 and the connecting part 2, so that the movable body 6 rotates between the slope of the pressurizing part 8 and the tip of the support shaft 12 that engages with it. The engagement state of the slopes of is changed, and the movable body 6 moves toward the spring 5, compressing the spring. That is, when closing the lid, the reaction force of the compressed spring 5 acts on the movable body 6 as a force that constantly moves it toward the spindle 12, and the movement of the movable body 6 toward the spindle 12 is prevented. Support 1, i.e.
This acts as a force to lift the lid, so even if you let go of the lid while it is closing, the lid will stop at that position or only gradually rise; it will not drop suddenly, and the audio Even in the case of a box that does not tolerate vibration, such as a box, the lid can be closed with peace of mind. When the lid is lowered to a certain extent, the gravity of the lid overcomes the force of the spring 5, and the lid gradually lowers and remains closed.

When opening the lid, the force of the spring 5 always acts as a force to lift the lid via the moving body 6, so the lid can be opened easily.

When opening and closing the lid, if the lid is lightweight,
The lid rises somewhat rapidly due to the force of the spring 5, but this hinge has the support shaft 3 in the shaft hole 11, the support shaft 12 in the connecting part 2, and the movable body 6 in the connecting part 2. Since the lid is inserted, each of them is made of synthetic resin so that friction is generated at each of the contact points, and this frictional force acts as a braking force against the sudden rise of the lid. from,
The lid can be opened and closed slowly and quietly.
As in the embodiment, the engaging piece 7 of the movable body 6 is connected to the connecting part 2.
By inserting it into the concave groove 4 of the lid and creating friction between these contact parts, it is possible to restrict the series of slides of the movable body 6 itself, and it is suitable for preventing sudden movement of the lid. . As shown in FIG. 14, if both end surfaces of the connecting part 2 and the connecting arm 10 are made sloped, it is easy to further increase the friction when opening and closing the lid. It is also suitable to make the surface slightly wavy.

In the embodiment, the connecting portion 2 is provided on the support body 1, but conversely, the connecting portion 2 is provided on the mounting body 9, the connecting arm 10 is provided on the support body 1, and the support body 1 is provided with the connecting portion 2 on the support body 1.
In other words, support 1 of the example
It is also possible to use the mounting body 9 with the mounting body 9 reversed.

As described above, in the hinge of the present invention, since the connecting arm 10 is stacked on the connecting part 2 and the movable body 6 is inserted into the connecting part 2, the frictional force for braking against the force of the spring 5 can be easily reduced. It is possible to obtain
To assemble each member, insert the compression spring 5 and moving body 6 into the connecting part 2, and connect the connecting arms 1 to both ends of the connecting part 2.
0A, 10B stacked and divided mounting bodies 9A, 9
B can be assembled by joining them together using a joining means such as the holder 13. That is, in order to connect the support body 1 and the attachment body 9, there is no need for a member to pass through them, so that assembly can be carried out efficiently and easily. And compression spring 5
The movable body 6, the support shaft, etc. can be made completely invisible from the outside, so that the appearance can be improved.
