2. Description of the Related Art Among hinges for opening and closing the lids of record player cabinets and other objects, there are already known hinges in which the opening and closing of the lid is facilitated by the force of a spring, or in which the opened lid is supported by the force of a spring provided within the hinge.

In this hinge, the elasticity of the spring is adjusted according to the weight of the lid by moving the screw shaft forward and backward. The structure is such that the screw shaft is moved forward and backward from the end opposite to the end where the support shaft of the rotating body to which the lid is attached is attached, and when it is installed in a cabinet etc. whose lid opens upward, Install it on the outside of the back wall of a cabinet, etc. with the spindle side facing upwards.

Therefore, when adjusting the screw shaft after installing the hinge in the cabinet, it is necessary to insert a screwdriver or the like from the bottom to the top of the hinge case.
There are many inconveniences in engaging a screwdriver or the like with the screw shaft, and there are many difficulties such as the cabinet becoming an obstacle when turning the screwdriver or the like.

In addition, since the fixed end of the screw shaft and the rotating body attached to the lid are in opposite positions, a U-shaped spring receiver is required that is attached coaxially with the rotating body for attaching the lid. Therefore, when the spring expands and contracts in response to the opening and closing of the lid, there is a problem in that the free end of the screw shaft moves in the radial direction, and it is necessary to support the free end of the screw shaft. .

The hinge of the present invention solves the above problem. A support wall is fixed to one end of the case, which is almost perpendicular to the peripheral wall of the case and projects inward of the case. The moving body having a concave cross section, the supporting member, the coil spring, and the adjustment plate are arranged in this order from the supporting wall side, and a screw shaft, which penetrates the supporting wall and has a head rotatably locked thereto, is arranged in order from the supporting wall side. It passes through the bottom plate between the opposing walls of the body, the support material and the coil spring in the axial direction, is screwed into the screw hole of the adjustment plate, and is attached by the coil spring on the support wall via the support material and the movable body. A rotating body having a concave cross-section is attached to the end of the case on the side having the support wall with a supporting shaft orthogonal to the screw shaft, and is spaced from the screw shaft in the radial direction. pivoted in position,
The movable body has its opposing wall side facing the rotating body, and each opposing wall of the movable body and the rotating body is positioned closer to the tip of the opposing wall of the rotating body than the support shaft and closer to the screw shaft than the support shaft. The rotating body has an adjustment hole on the screw shaft side at a position overlapping the screw shaft in the bottom wall between the opposing walls of the rotating body, and a mounting plate for the lid is provided on the rotating body.

To explain the embodiment of the hinge of the present invention as shown in the drawings, reference numeral 1 is a case with a concave cross section that is fixed to a cabinet etc., and at one end in the length direction, it is perpendicular to the peripheral wall and protrudes inward of the case 1. A support wall 2 is fixed.

Reference numeral 3 denotes a support shaft installed at the end of the case 1 where the support wall 2 is provided, with its axis parallel to the width direction of the support wall 2, and a rotating body 4 having a concave cross section is mounted on this support shaft. , are pivoted on both opposing walls.

5 is the bottom wall between the two light walls of the right moving body 4, and 6 is a mounting plate provided continuously on the bottom wall 5 of the rotating body 4 on the side where there is no opposing wall, to which the cabinet lid is attached. It will be done.

The mounting plate 6 is oriented in the opposite direction to the mounting surface of the case 1 to a cabinet or the like.

Reference numeral 7 denotes a movable body having a concave cross-section, both opposing walls of which are stacked on each of the opposing walls of the rotating body 4, and are pivoted to each other.

8 is a bottom plate between the side facing walls of the movable body 7, and its outer surface is connected to the support shaft 3.
The surface is curved in the same direction as the circumferential direction.

Reference numeral 9 denotes a supporting member made of synthetic resin or the like which is placed overlappingly on the outside of the bottom plate 8, and the surface facing the bottom plate 8 is a concave curved surface into which the bottom plate 8 is inserted.

10 is a coil spring arranged on the side of the support member 9, and 11 is a screw shaft, which passes through the bottom plate 8, the support member 9, and the spring 10 from a hole provided in the support wall 2 at a position that does not overlap with the support shaft 3. do,
It is inserted into the case 1, and the head 12 is rotatably locked to the support wall 2.

Reference numeral 13 denotes an adjustment plate attached to the tip of the screw shaft 11 with a screw, and supports the spring 10.

The pivoting position of the moving body 7 with respect to the rotating body 4 is such that the screw shaft 11 is closer to the tip of the opposing wall of the rotating body 4 than the supporting shaft 3, and
Being in a side position.

14 is an adjustment hole provided in the bottom wall 5 so as to overlap the head 12 of the screw shaft 11; 15 is a fixing plate provided perpendicularly to the edge of the opposing wall of the case 1; and 16 is a lid provided on the mounting plate 6. The mounting screw 17 is a stopper installed between the opposing walls of the case 1, which supports the rotating body 4 when the lid is opened.

18 is a cabinet, 19 is a receiving plate provided in the cabinet 18, and 20 is a lid.

In the above configuration, the position of the stopper 17 is arbitrary, and a part of the cabinet can also be used as the stopper.

The configuration of the hinge in this case is as described above, and to explain the opening and closing of the lid using this for a lid that opens upwards, the case 1 is installed inside a cabinet etc. with a screw shaft 1.
1 in a horizontal direction, the mounting plate 6 is exposed from the back wall of the cabinet, and the cabinet is mounted with a fixing plate 15.

Therefore, the back wall of the cabinet is removed to such an extent that the bottom wall 5 of the rotating body 4 is exposed and the rotation of the rotating body 4 is not hindered.

Incidentally, the case 1 is fixed on a support plate 18 provided horizontally inside the cabinet or fixed to the inner surface of the side wall of the cabinet. When fixed to the side wall of the cabinet, the direction of the fixing plate 15 is adjusted accordingly. Let's set it.

A mounting plate 6 is superimposed on the outer or inner surface of the lid and fixed with mounting screws 16 or the like.

If the lid is a plate, attach the mounting plate 6 to the case 1 from the state shown.
Bend approximately 90' to the side and attach to it.

When the lid is closed, the rotating body 4 is in the state shown by the solid line in FIG. 1, compressing the spring 10.

That is, when the lid is closed, the moment becomes maximum due to the movement of its center of gravity, and the lid overcomes the elasticity of the spring 10 and maintains the closed state.

To open the lid, just lift it a little, and the spring 10 will use its elasticity to lift the lid upwards via the rotating body 4, making it easy to open. However, the elasticity of the spring 10 prevents the lid from dropping suddenly, and even in cases such as a record player, the lid can be easily opened and closed without imparting vibration to it.

When the lid opens to the specified position, stopper 1 installed at the appropriate position
The rotating body 4 hits the cabinet 7 or the cabinet and stops, and the spring 10 maintains this state with its elasticity.

When closing the lid, by pressing it lightly, the lid rotates the rotating body 14, moves the movable body 7, and gently descends without compressing the spring 10.

In order to smoothly open and close the lid using the elasticity of the spring 10, it is necessary to adapt the elasticity of the spring 10 to the weight of the lid.
However, in the hinge of this invention, a support wall 2 is provided in the case 1, and the screw shaft 11 is moved from the support wall 2 to the case 1.
The head 12 of the screw shaft 11 is rotatably latched to the support wall 2, and the rotating body 4 is attached to the support wall 2 side.

Therefore, when fixing the case 1 to a cabinet or the like, for example, as illustrated in FIG. Can be fixed as a cutout in the side wall of the cabinet.

That is, since the head 12 of the screw shaft 11 is exposed outside the cabinet at the cutout in the side wall of the cabinet, when turning the screw shaft 11, the screwdriver must be moved horizontally from outside the cabinet. Can be used.

Therefore, it is easy to engage the screwdriver in the groove of the head 12 and turn it, and the elasticity of the spring 10 can be adjusted extremely easily and accurately after the case 1 is fixed to a cabinet or the like. Yes, spring 1
The lid can be opened and closed more smoothly by effectively using the zero elasticity.

Furthermore, since the case 1 can be installed inside the cabinet, the appearance can be improved.

This hinge can also be installed on the outside of the back wall of the cabinet. In that case, as shown in FIG. In this case, the screw shaft 11 can be adjusted from above, and as in the case described above, the adjustment is extremely easy and precise adjustment is possible.

Therefore, it can be used to open and close the lids of record player cabinets and other lids, and the lids can be opened and closed smoothly.

A spring 10 is attached to the outer periphery of a screw shaft 11 whose head 12 is supported by a support wall 2 provided at the end where the rotating body 4 of the case 1 is pivoted.
is arranged, the screw shaft 11 is well stabilized even when the rotating body 4 rotates and the spring 10 is compressed when the lid is opened/closed, and the structure provides special support for the free end side of the screw shaft 11. can be omitted, and the force of the coil spring 10 can be applied to the rotating body 4 appropriately.
