Description

[Detailed Description of the Invention] The present invention relates to a hinge device used in record players and the like.

2. Description of the Related Art Devices with a lid, such as a record player, require a hinge device to open and close the lid.

A hinge is usually used as such a hinge device, but the hinge can only take two states: the first state where the lid is open and the second state where the lid is closed, and it holds the lid in the half-open state. I can't do that.

Furthermore, depending on the arrangement of record players, the user often has to remove the cover from the player body, but in the case of a record player using a normal hinge, the screws must be removed, which is troublesome.

The present invention has been developed in view of the above points, and aims to provide a hinge device that allows the lid to be left in a half-open state and allows the lid to be easily removed for sushi.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hinge device according to the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a hinge body made by molding a composite resin, 2 is an L-shaped arm rotatably connected to the hinge body, and the hinge body 1 includes:
It consists of a curved section 3 and a pair of legs 4 and 5, and the curved section 3 has a hole 6 into which one end of the arm 2 is inserted.

Further, the arm 2 has a locking portion 7 in the middle thereof, and the locking portion 7 is used as a stopper and for regulating the position when the tip of the arm 2 is inserted into the mounting hole of the lid, as will be described later.

Since the curved part 3 of the hinge main body 1 is made by molding or resin molding, it has elastic force and the pair of legs 4
and 5 in the direction of arrow A.

Further, the pair of legs 4 and 5 are processed to become narrower as they go downward in the figure.

FIG. 2 is a perspective view showing the hinge device shown in FIG. 1 attached to a record player.

The cabinet 17 of the record player is made of resin, iron plate, etc. that can be easily processed into a certain shape.
A hinge attachment body 8 is provided integrally or separately on the back surface of the body.

The hinge mounting body 8 is open at the bottom and has a hole 9 at the top for allowing the tip of the L-shaped arm 2 to protrude.

When attaching the hinge to the cabinet, insert the hinge body 1 together with the arm 2 attached to the hole 6 of the hinge body 1 into the opening of the hinge mounting body 8, and then insert the arm 2 into the opening of the hinge mounting body 8.
It is only necessary to properly arrange the tip of the hinge mount B at a position such that it protrudes from 7L9 of the hinge mount B, and fix the pair of legs 4 and 5 of the hinge to the hinge mount 8 using the screws 10 and 11.

The screws 10 and 11 are used to attach the hinge to the cabinet, and are also used to adjust the rotational state of the arm 2.

That is, nuts corresponding to the screws 10 and 11 are provided on the other leg portion 5 of the hinge that does not contact the hinge mounting body 8.
(not shown) is provided.

Therefore, when screws 10 and 11 are tightened, the elastic force A
Against this backdrop, the distance between the pair of legs 4 and 5 narrows, and the contact friction between the inner surface of the hole 6 of the hinge body 3 and the arm 2 increases, making it difficult for the arm 2 to rotate.

In particular, in the hinge device according to the present invention, the pair of leg portions 4
Since the widths of the upper and lower sides are different, it has the advantage that sufficient contact friction can be obtained compared to a case where the upper and lower widths are parallel, and for example, it is possible to absorb dimensional errors in the diameter of the arm 2. It has practical effects.

Further, the rear end of the hole 9 of the hinge mounting body 8 is connected to a groove 13 provided in the back plate 12 of the mounting body 8, as shown in FIG.

The groove 13 serves as a stopper for the arm 2 when the lid is opened, and the maximum opening angle of the lid can be adjusted by adjusting its depth.

FIG. 3 is a partial side view showing the relationship between the lid 14 and the cabinet 17, where A shows the lid in a closed state, and the opening shows the lid in an open state.

As is clear from FIG. 3, the rear end of the lid 14 has a mounting hole 15.
A mounting portion 16 having a diameter is provided, and the tip of the arm 2 of the hinge is loosely fitted into the mounting hole 15.

The locking portion 7 of the arm 2 is for adjusting the loose fit between the arm 2 and the mounting hole 15, and the presence of the locking portion 7 maintains a predetermined loose fit state.

Since the cabinet 17 and the lid 14 are connected only by the arm 2, when the lid 14 is removed, it is only necessary to release the loosely fitted state between the mounting hole 15 and the arm 2, which is very simple.

As described above, the hinge device according to the present invention has a very simple structure and is a practical device that can achieve various effects.
