Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an improvement of a record player cabinet.

(b) Conventional technology Many conventional record player cabinets are known to be integrally molded from resin (for example, "Player System and Its Effective Use", (published on January 20, 1982), Seibun. Doshinkosha, p.259).
However, the molding machine for integrally molding the cabinet with resin required a fairly large machine weighing about 600 tons, and the problem was that it was relatively expensive due to poor productivity.

Also, when aiming for a design effect by using two colors for the cabinet, it is necessary to go through the process of covering the surface of the cabinet of one color with a jig or tape, and then painting it with the other color. However, there were problems in that the defective rate was high and the production volume was extremely low, resulting in extremely high costs.

(c) Problems that the invention aims to solve This invention solves the problems caused by integral molding of record player cabinets, namely that it requires a large molding machine, has low productivity and is expensive, and also improves the design. The purpose of the present invention is to provide a cabinet device that can easily obtain various effects and has a high degree of freedom in design.

(d) Means for Solving the Problems The resin cabinet of the record player is composed of a pair of cabinet halves, which are joined at a joint and fixed parts are connected to form an integral unit.

(e) Function Since the record player cabinet is constructed by separating into two resin cabinet halves, a large molding machine and mold are not required. Furthermore, since the one half of the cabinet and the other half of the cabinet are separate, they can be made of different resins.

(f) Examples The present invention will be explained below with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of an embodiment of the present invention. A record player 1 is provided with a dust cover 2, a tone arm 3, and a turntable 4, and a resin (for example, styrene resin) cabinet 5 is divided into a front portion 5a and a rear portion 5b.

FIG. 2 is a plan view of the cabinet, and FIG. 3 is a perspective view of the same essential parts, with A showing the front part of the cabinet and B showing the back surface of the rear part.

The cabinet 5 is composed of a pair of cabinet halves, namely a front part 5a and a rear part 5b.
5c and 5d are recesses for placing the turntable 4. A plurality of fixing parts 6 having through holes 6a are provided in the front part 5a of the cabinet 5 near and along the joint part 7, and a locking piece 7a is formed in the joint part 7. .

At the rear part 5b of the cabinet 5, a plurality of bosses 8 having screw holes 8a at positions corresponding to the fixing parts 6 are provided along a joint part 9. A locking piece 9a is provided at a position corresponding to the piece 7a.

The locking pieces 7a, 9a are formed in a hook shape so as to be locked to each other along at least a part of the joint surfaces of the respective joint parts of the cabinet halves 5a, 5b.

In order to integrate the front part 5a and the rear part 5b of the cabinet 5, it is necessary to make sure that the locking piece 7a provided at the joint 7 of the front part 5a and the locking piece 9a provided at the joint 9 of the rear part 5b are joined. Next, the bosses 8, 8, 8 of the rear part 5b are inserted into the through holes 6a, 6a, 6a provided in the plurality of fixing parts 6, 6, 6 of the front part 5a.

Next, screws 10, 10, 10 are passed through the screw holes 8a, 8a, 8a, and the boss 8 is fixed to the fixing part 6 with the screws 10, as shown in FIG.
As a result, the front portion 5a and rear portion 5b of the pair of cabinet halves, ie, the front portion 5a and rear portion 5b of the cabinet 5, are integrated and used as a cabinet for a record player. Note that the end surface 7b of the locking piece 7a comes into contact with the back surface 5d of the rear portion 7a, and holds the surfaces of the front portion 5a and the rear portion 5b at the same height.

Since the fixing part 6 and the boss 8 provided on the front part 5a and rear part 5b of the cabinet 5 are connected near the joining part thereof, the two parts are reliably integrated without wobbling. Furthermore, as shown in Figure 4, the locking pieces provided at the joints of the two are hook-shaped and configured to pull against each other, making it possible to position the joints and prevent vibrations received by the joints. Chatter is prevented. It goes without saying that if an extremely thin resin sheet is interposed between the joints, chattering can be prevented even if play occurs between the joints due to dimensional variations.

The connection between the fixing parts can be selected as appropriate without using screws, such as by providing an engaging pawl on one side and an engaging hole on the other side.

Although the front part 5a and rear part 5b of the cabinet 5 may be molded with the same resin, the degree of freedom in design is further increased by molding them with different resins.
For example, if the front part is molded with red resin and the rear part with black resin, a design effect can be obtained. A similar effect can be obtained even if the cabinet is divided into left and right halves instead of front and rear.

In addition, in order to make the load on the insulator of the record player uniform, the half of the cabinet on the side that bears the weight of the record player as a whole is made of a resin with a low specific gravity, and the other half of the cabinet is made of a resin with a high specific gravity. Howling characteristics can also be improved.

Furthermore, unlike conventional integrally molded cabinets, the molding machine does not require a large one and can mold even objects weighing around 200 tons, improving productivity, making it possible to manufacture cabinets at low cost.

(g) Effects of the invention As described above, the invention provides a system in which the joints of one half of the resin cabinet and the other half of the cabinet are locked to each other along at least part of their joint surfaces. A hook-shaped locking piece is formed, and a fixing part is formed for fixing each half of the cabinet so that the upper surface thereof is flush with the upper surface thereof, and the joint part of each of the cabinet halves is positioned by the locking piece. and is configured to be fixed by the fixing part,
Furthermore, the one half of the cabinet and the other half of the cabinet can be molded using resins of different materials, and a turntable that becomes circular when joined is mounted on the upper surface of each half of the cabinet. A recess is formed, one half of the cabinet constitutes the front side of the record player body, and the other half of the cabinet constitutes the rear side of the record player body. The halves are positioned using their locking pieces to prevent vibrations caused by chatter, and moreover, the design effect of the record player body can be improved. Furthermore, since the front and rear sides of the cabinet halves are molded separately, howling characteristics can be improved by molding the heavier side of the cabinet half from a resin with a higher specific gravity. Therefore, the practical effects of the present invention are great.
