Description

[Detailed Description of the Invention] This invention particularly relates to a mounting structure for a rear hinge for opening and closing a dust force bar of a record player.

The hinge for opening and closing the dust force bar of a record player includes a side hinge installed between the side plate of the dust force bar and the rear top of the cabinet, and a rear hinge installed between the rear plate of the dust force bar and the rear top of the cabinet. Compared to the latter, the rotation fulcrum of the former moves toward the front of the dust force bar, so it prevents the rear part of the open dust force bar from protruding toward the rear of the cabinet and saves space for installing the record player. Although it has the advantage of saving money, it has the disadvantage that the structure is complicated, which increases the price, and that the rear plate of the dust force bar must be removed, making it easier for dust to enter there.

On the other hand, the latter has a relatively simple structure and is therefore inexpensive, and has the advantage of being able to prevent dust from entering as much as possible; , the disadvantage is that the rear of the open dust force bar protrudes to the rear of the cabinet.

The purpose of this invention is to install a rear hinge that can prevent itself from protruding toward the rear of the cabinet even if the rear hinge is used, and furthermore prevent the rear of the open dust force bar from protruding toward the rear of the cabinet as much as possible. It is intended to provide structure.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.
A spring case portion 1b is provided at the lower central end of the dust force bar holding portion 1a so as to protrude slightly forward, and a spring case portion 1b is provided on both sides of the spring case portion 1b so as to similarly protrude slightly forward. It is a supporting member made by processing a certain composite resin such as polyacetal into a shape from the caulking pin attachment parts 1c and 1c, of which the dust force bar holding part 1a is provided with a groove 1d, The caulking pin attachment parts 1c, 1c are provided with vertical grooves 1e, 1e, and the rear lower end of the dust force bar 2 is inserted and held in the groove 1d.

Reference numeral 3 denotes a mounting member made by bending a steel plate so that its planar cross section has a substantially U-shape.
, 3a and a mounting insertion portion 3b provided with reinforcing ribs 3c, 3c, which are integrally connected to the lower portions of the side plates 3a, 3a and have a low rise on the left and right sides.

Of these, the side plates 3a, 3a are attached to the longitudinal grooves 1e, le of the support member 1 together with a friction member 5 such as a fiber attached to each outer surface and an elastic member 6 such as a spring washer.
The friction member 5 and the elastic member 6 are connected to each other by a caulking pin 4 such that their pivot points are located slightly forward of the groove 1d provided in the dust force bar attachment portion 1a.

A torsion coil spring 7 wound around a caulking pin 4 is elastically installed between the support member 1 and the mounting member 3, and this torsion coil spring 7 is housed in the spring case portion 1b. ing.

On the other hand, a recess 8a whose upper and rear parts are open is provided at the rear upper end of the cabinet 8, and a storage hole 8b is provided at the bottom of the recess 8a facing downward.

The portion of the mounting member 3 to which the caulking pin 4 is attached is housed in the recess Ba of each spring case portion 1b of the support member 1, and the mounting insertion portion has a substantially irregular U-shaped planar cross section. The portion 3b is inserted into the storage hole 8b.

Therefore, especially when the mounting member 3 is attached to the cabinet 8 as shown in FIG.
The part to which the hinge pin 4 is attached, including the side plates 3a, 3a, is stored in the recess 8a, and the mounting insertion part 3b is stored in the storage hole 8b, so that the cabinet 8
Since the support member 1 does not protrude to the rear and the pivot point of the support member 1 is located forward of the groove 1e provided in the dust force bar holding portion 1a, the rear part of the dust force bar 2 can be held in a closed state. It is aligned with the rear part of the cabinet 8 and does not look ugly.

Next, especially from the state shown in FIG. 2, the dust force bar 2
When opened, the dust force bar 2 is opened by the elasticity of the torsion coil spring 7 without really feeling its weight, and the torque of the torsion coil spring 7 and the weight of the dust force bar 2 are balanced. At certain angles, it will not close even if you release your hand and will remain open.

This angle is 40 to 50 degrees in this embodiment.

When the dust force bar 2 is opened from this state, the dust force bar 2
is further pushed open and stopped when the protrusions If, if provided on the caulking pin attachment parts IC, 1C abut against the base plate 3d of the attachment member 3.

This angle is approximately 65 degrees in the embodiment.

In this state, the pivot point of the support member 1 is
By housing the hinge pin 4 in the recess 8a, the pivot point of the support member is located in front of the dust force bar, rather than in the conventional case where the pivot point of the support member is located slightly behind the rear end surface of the cabinet. This makes it possible to prevent the rear part of the opened dust force bar from protruding to the rear of the cabinet 8 as much as possible, and also eliminates the need to remove the rear plate of the dust force bar 2 by using a side hinge. Therefore, it is possible to prevent dust from entering the inside of the dust bar as much as possible.

Next, when the front end of the dust 1/cover 2 is pushed down, the dust force bar 2 is closed, but due to the elasticity of the torsion coil spring 7, it does not close suddenly and make a noise.

The friction member 5 and the elastic member 6 provide a comfortable opening/closing sensation when the dust force bar 2 is opened and closed, and hold the dust force bar at an intermediate opening angle, and furthermore, when the dust force bar 2 is opened or closed at a certain opening angle, the dust force bar 2 is held at an intermediate opening angle. It performs functions such as braking the dust force bar 2 which tends to spring up due to the elasticity of the torsion coil spring 7.

Next, the dust force bar 2 can be removed from the dust force bar holding part 1a by opening it and pulling it upward, and by pulling this, the hinge mounting member 3 can be removed from the storage hole. 8b, and by applying the rear lower end of the dust force bar 2 and the mounting insertion part 3b of the mounting member 3 to the dust force bar holding part 1a and the storage hole 8b and pressing down, the dust force can be easily removed. It can be attached to the bar holding portion 1a or the storage hole 8b.

As explained in detail above, this invention can prevent the mounting member of the rear hinge itself from protruding toward the rear of the cabinet without losing the function of the conventionally known rear hinge for opening and closing the dust force bar. In addition to enhancing the aesthetic appearance of the record player, the dust force bar can be freely attached to and removed from the cabinet at each hinge, and the rear part of the open dust force bar can be extended to the rear of the cabinet. This also has the effect of saving space for installing the record player.
