What is known so far as a cabinet for an entertainment device using an optical disc such as a CD player, a DVD player and the like is a cabinet having a lid rotatably attached to the cabinet body, the lid being opened and closed using elastic force. Such cabinets are generally configured in such a way that the lid is rotatably attached to the inner surface of the cabinet body by a hinge or other mechanism, and a spring or other propulsion means is installed inside the cabinet body to open the lid by the elastic force of the spring. On the cabinet body away from the part to which the cover is attached, a coupling member is generally provided which advances and retracts with respect to the cover, which can be closed by engaging the end of the cover with the coupling member. The engaging member generally has an inclined surface in contact with a button or other pressing member, and when a user presses a button, the pressing force through the inclined surface acts as a force in the forward and backward direction of the engaging member, and the cover From the end of the. When the user releases the button, the engagement member returns to its original position and the lid and engagement member engage so that a spring or other propulsion means is placed on the end of the base in the forward and backward direction of the engagement member.

However, in the above-described conventional electronic device cabinet, since the coupling structure of the cover is composed of a button, a coupling member, a propulsion means, and a plurality of components, a lot of work is required during assembly, and it is difficult to efficiently assemble the electronic device. . Thus, the assembly work is complicated because the spring or other propulsion means must be placed on the end of the bottom of the engaging member in a bent state during assembly.

An electronics cabinet having a cabinet body and a lid rotatably attached to the cabinet body has a coupling member for advancing and retracting the lid and engaging the ends of the lid to hold the lid closed. The coupling member has a coupling body for engaging the end of the cover and propulsion means for moving the body in the forward and backward directions. The coupling unit body and the pushing means are formed integrally. Due to the integrated structure, the coupling member body and the propulsion means can be attached only by installing the coupling member on the cabinet body, thereby greatly simplifying the assembly work. The cabinet can be used for entertainment devices such as CD players or DVD players or game devices, and the configuration of the present invention can be used for such electronic devices to simplify the structure of the cabinets, making the electronic devices smaller and lighter and reducing costs. Can be reduced. The propulsion means has a symmetrical configuration in order to apply a uniform force to the coupling member, preferably formed in the form of a ring. It is preferable to install a guide on the cabinet body to adjust the movement of the coupling unit body. Since polyacetal has good fatigue resistance as a good sliding material, it is preferable to configure the coupling member by integral molding of injection molded polyacetal.

Preferably, a hole is formed in the cabinet body so that the cover can be fitted by pressing the cover, and a recess is formed around the hole so that the circumference of the cover is exposed from the outer surface of the recess while the cover is pressed into the hole. desirable.

In addition, the cabinet body includes a pair of receiving members. The accommodating member is coupled to each other to accommodate the inside of the apparatus main body having the electronic component or the like. The cabinet body is formed with an opening that exposes a connection terminal provided on the apparatus body for connection of an external device. This opening is located over the boundary of the pair of receiving members.

Here, the connection terminal for the connection of the external device, for example, an audio and video output terminal that is connected to the control device to output a signal from the device body to the TV receiver, a power supply for supplying power to the device body from an external power source It may include a terminal. However, it is not limited thereto.

Further, the opening formed at the boundary (coupling line) of the pair of storage members may include, for example, an opening composed of holes formed in each of the pair of storage members facing the boundary, and the pair facing the boundary. It may include an opening made of a hole formed in one or the other of the receiving member. However, it is not limited thereto.

Therefore, the pair of housing members constituting the cabinet body is generally formed by injection molding using a metal mold having an upper mold (cavity) and a lower mold (core). Accordingly, when it is desired to form an opening in the accommodating member that exposes the connection terminal provided in the main body of the apparatus, the accommodating member (1) joins the upper and lower molds and inserts a horizontally moving slide core into the metal mold, (2) Resin is injected into this metal mold, (3) the slide core is moved and removed from inside the metal mold, and (4) the upper mold is lifted and formed by separating the molding from the mold. However, this process requires an additional step for moving the slide core, which causes a problem of lowering the productivity of the receiving member.

Therefore, if the openings are formed at the boundary of the pair of storage members without forming the openings in the interior of the storage member, the openings facing the boundary can be formed sufficiently in the respective storage members, so that the slide core is unnecessary. Accordingly, the manufacturing step can be reduced, and the productivity of the housing member can be improved.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. Like reference numerals in the drawings denote like parts.

1 shows a TV receiver 3 for outputting video and sound, an entertainment device 1 which is an electronic device connected to the TV receiver 3, and a control device 2 which is an operation device for sending commands to the entertainment device 1; Has shown a part of the living room 100 is installed. The entertainment apparatus 1 executes the game program according to an instruction sent from the control apparatus 2 operated by a user (game player), for example, by reading a game program or the like recorded on an optical disc.

As shown in Fig. 2, the entertainment apparatus 1 includes a device body (not shown) including electronic components, a cabinet body 10A, an upper case 11, and a lower case 12. It is configured to include a flat rectangular entertainment device cabinet (10) to be combined with the device body. The upper case 11 and the lower case 12 is preferably formed by injection molding.

The upper case 11 is provided with a circular cover 13 having a flat and nearly round shape installed in the center portion of the upper case body 14. This cover 13 is made to close when it is pressed into the opening 14E. A recess 14F is formed around the opening 14E so that the edge of the cover 13 is exposed to the outside when the cover 13 is fitted in the opening 14E (see FIG. 2). . The lower case 12 covering the device body from below is made in such a manner that its end engages with the end of the upper case body 14. The portion where these ends are coupled to each other becomes a boundary between the lower case 12 and the upper case 11.

To the left of the lid 13 is a power button 15, which is activated when the device is turned on or off. On the right side of the cover 13, an open-close button 16 is provided. This button 16 is activated when the cover 13 is opened or closed. Two slots 17, which are connection terminals for connection of external devices, are exposed on the side of the cabinet 10 as shown in the front of Figs. Each slot 17 has a memory card insert 18 located above and a control device connection 19 located below. The memory card inserting portion 18 is for inserting a memory card or other external auxiliary memory device, and spans the boundary (coupling line) between the upper case body 14 (upper case 11) and the lower case 12. The insertion hole 18A to be positioned preferably has a rectangular shape and is formed to have a long side in the horizontal direction. A cover 18B is provided on the memory card insertion section 18. The cover 18B is for protecting a connection terminal provided in the insertion section. The insertion holes 18A are formed in the upper case body 14 (upper case 11) and the lower case 12, respectively, and are positioned toward the boundary between the upper case body 14 and the lower case 12 ( 31,32). The control device connecting portion 19 is an input / output terminal for inputting / outputting a signal, and is connected to a connection terminal (not shown) formed at an end of a control device cable extending from the control device 2 (see FIG. 1). The insertion hole 19A has a rectangular shape, but preferably has a long side in the horizontal direction, and preferably has a lower edge more rounded than the upper edge. Forming the insertion hole 19A in this manner can prevent the connection terminal (not shown) of the control device 2 from being connected in the wrong direction. In addition, since the shape of the insertion hole 19A is different from that of the insertion hole 18A of the memory card inserting portion 18, an external auxiliary memory device may be incorrectly inserted into the insertion hole 19A of the control device connecting portion 19. There is no risk, and vice versa is prevented from occurring.

A power connector (not shown) is installed on the surface opposite to the surface on which the slot 17 is located. This power connector is a power terminal to which an AC adapter (not shown) is connected, and this power terminal is a video recorded on an optical disc (not shown) with the device main body and the power from an external power source (not shown). Signals, audio signals and other various signals are supplied to video and audio output terminals (not shown) for outputting to the TV receiver 3. In addition, an opening (not shown) is formed by an opening formed on the lower case 12 that faces the interface between the upper case body 14 and the lower case 12 similarly to the insertion hole 18A. Openings expose the power connector and video and audio output terminals to the outside.

As shown in FIG. 3, the cover 13 includes a flat circular disk cover 21. As shown in FIG. The cover portion 21 extends from the edge of the disk mounting portion 20 on which the optical disc 4 is placed, and the edge of the disk cover portion 21, the end of which is rotatably attached to the upper case body 14 by a hinge mechanism. It is comprised with the connection part 22 attached. A spring 14A is installed inside the upper case body 14. One end of this spring is in contact with the cover 13 to bring the cover 13 to the open position as shown in FIG.

At a portion around the edge of the disc cover portion 21, a rod-shaped member 21A is formed to protrude toward the lower case 12. This rod-shaped member 21A serves to press an open-close detection switch (not shown) which detects whether the cover 13 is open or closed. A rectangular coupling piece 21B is provided at a portion around the edge of the disc cover portion. The recess 21C is located at the center of the rectangular engagement piece. The rod-shaped member 21A and the engaging piece 21B are formed on the disc lid 21 at a position corresponding to or aligned with the position of the open-close button 16.

Referring to Fig. 4, the open-close button 16 is exposed to the outside and is pressed by the user, and is positioned on the upper case body 14 below the press member 23. It includes a coupling member (24). The pressing member 23 has a pressing portion 23A, the cross section of which is in the form of "C" and has a flat circular shape. The pressing member 23 also has a connecting portion 23B. This connecting portion 23B is formed in the center portion on the coupling member 24 on the side of the pressing portion 23A. The end of the connecting portion 23B is in contact with the coupling member 24, the side has a rectangular shape.

As shown in Figs. 4 to 7, the engaging member 24 moves forward and backward with respect to the engaging piece 21B of the disc cover portion 21 (arrow A in Fig. 4), and the engaging piece 21B. Use to keep the cover 13 closed. The coupling member 24 is provided with a coupling part main body 25, the coupling part main body 25 is a coupling means 21B, and the propulsion means for moving the coupling part main body 25 in the forward and backward directions ( 26). The coupling member 24 is preferably configured by integral molding of injection molded polyacetal. The coupling part body 25 includes a flat body upper portion 27 of the protruding shape and a flat body lower portion 28 of the protruding shape. The upper body 27 is exposed to the outside when the pressing member 23 is removed. The body bottom 28 is formed below the body top 27 and is slightly smaller than the body top 27. The upper body 27 fits comfortably between the pair of guides 14B formed on the upper case body 14. Accordingly, the coupling member 24 may be adjusted to move perpendicularly to the forward and backward directions. The end of the main body upper portion 27 is a surface 27A inclined toward the center portion of the disc mounting portion 20 (see Fig. 4). The tip of this inclined surface 27A projects into the disc mounting portion 20 by moving toward the disc mounting portion 20 by the pushing means 26 without pressing the button 16 downward. In this way, the cover 13 can be kept closed by the engaging end 27A in the recess 21C of the engaging piece 21B. The lower body 28 is formed in the upper case body 14 and fits comfortably in the opening 14C (see Fig. 7) having a shape similar to the flat shape of the lower body 28. Accordingly, the coupling member 24 may be adjusted to move vertically with respect to the forward and backward directions. Flat rectangular through-holes 29 are formed in the substantially central portion of the upper body 27 and lower body 28, respectively. Of the inner surfaces forming the through hole 29 perpendicular to the long side direction of the coupling part body 25, the inner surface formed on the side of the propulsion means 26 is an inclined surface toward the disc mounting part 20. (29A). The connecting portion 23B of the pressing member 23 is in contact with this inclined surface 29A (see Fig. 4). Accordingly, when the user presses the pressing member 23, the inclined surface 29A is pressed by the connecting portion 23B, and the coupling member 24 is coupled to the coupling piece by the compressive force acting on the inclined surface 29A. 21B) to move away. In other words, the compressive force is converted by the pressing member 23 to the force in the forward and backward directions of the engaging member 24 by the inclined surface 29A to separate the engaging member 24 from the engaging piece 21B.

The propulsion means 26 is formed in a ring shape when viewed in plan view, and is positioned to be symmetrical with respect to the center line in the long side direction of the coupling member 24. One end of the propulsion means 27 opposite the engaging body 25 is in contact with a receiving part 14D having an L-shaped cross section formed in the upper case body 14. In this way, the propulsion means 26 maintains the above-mentioned elastic force between the engaging portion body 25 and the receiving portion 14D. When the user releases his or her hand from the pressing portion 23A or closes the cover 13, the engaging member 24 is automatically returned to its original position by the pushing means 26 so that the engaging member 24 13) can be automatically combined. The coupling member 24 fits the lower part of the body 28 to the opening 14C comfortably in a state where the contact portion 14D of the propulsion means 26 is bent. Then, the upper case body 14 can be attached by correcting the bending of the propulsion means 26 so that the propulsion means 26 enters the receiving portion 14D.

The operation of opening and covering the cover 23 of the entertainment apparatus 1 is as follows.

First, when the lid 13 is closed (FIGS. 2 and 4), that is, when the end portion 27A of the upper body 27 is located in the recess 21C of the engaging piece 21B, the user When the pressing member 23 is pressed, the connecting portion 23B of the pressing member 23 is inserted into the through hole 29 of the engaging portion main body 25 to press the inclined surface 29A. The coupling member 24 moves in the direction away from the engaging piece 21B by the compressive force applied by the connecting portion 23B to the inclined surface 29A. In this manner, the end portion 27A of the upper body 27 is separated from the coupling piece 21B so that the cover 13 is released by the elastic force of the spring 14A.

When the user releases the pressing portion 23A, the compressive force applied to the inclined surface 29A disappears, and the engaging portion 25 moves toward the disk mounting portion 20 by the pushing force of the propulsion means 26, and the engaging member 24 returns to its original position.

When the cover 13 is closed while the optical disk 4 is placed on the disk mounting portion 20, the cover 23 is pushed toward the disk mounting portion 20 so that the lower portion of the coupling piece 21B is the upper portion of the main body 27. Pressing the inclined surface 27A at the end of the engaging member 24 is moved in the direction away from the engaging piece 21B. In addition, when the cover 13 is pressed toward the disk mounting portion 20, the engaging member 24 away from the engaging piece 21B moves toward the recess 21C of the engaging piece 21B, so that the end of the upper portion of the main body 27 is closed. This engaging piece 21B is engaged. In this way, the cover 13 can be closed.

Therefore, since the coupling part main body 25 and the propulsion means 26 are integrated, the coupling part main body 25 and the propulsion means 26 can be attached simply by fitting the coupling member 24 onto the upper case main body 14. Therefore, the assembly operation of the electronic device cabinet of the present invention can be simplified. In addition, since the propulsion means 26 is configured symmetrically with respect to the coupling member 24, the driving force in the forward and backward directions can be applied to the coupling member 24 uniformly from side to side. In addition, by configuring the propulsion means 26 in the form of a ring it is possible to simplify the structure.

In addition, the guide 14B is formed on the upper case body 14 to adjust the movement of the coupling body 25 along the forward and backward directions and is positioned in a direction perpendicular to the forward and backward directions of the coupling member 24. Therefore, the coupling member 24 can be mounted along the guide 14B, thereby further simplifying the assembly work of the cabinet of the present invention.

In addition, since the coupling member 24 is made of polyacetal having a good sliding material and excellent fatigue resistance, it is possible to smoothly move the coupling body 25 along the upper case body 14, and the propulsion means 26 Propulsion of) can be maintained for a long time.

In addition, since the recess 14F is formed around the edge of the opening 14E of the upper case body 14, the lid 13 is attached to the upper case body 14, and then the lid 13 is attached. In the case of confirming, when the finger touches the edge of the cover 13 exposed by the recess 14F, the cover 13 can be easily opened and closed. Accordingly, it is easy to check whether the cover 13 is coupled to the upper case body 14. In addition, the recess 14F is formed at or around the edge circumference 14E of the upper case body 14 and is equal to or lower than the height of the optical disc 4 (see FIG. 3) into which the bottom of the recess 14F is inserted. Because of its location, it is easy to access the optical disc, especially the edge of the disc, which is inserted for removal from the cabinet.

In addition, since the insertion hole 18A is formed at the boundary between the upper case body 14 and the lower case 12, an opening can be sufficiently formed in each of the upper case body 14 and the lower case 12, so that a slide core is required. There will be no. Accordingly, the manufacturing step can be reduced, and the productivity of the upper case 11 and the lower case 12 can be increased.

The present invention is not limited to the above-described embodiments and includes other configurations and modifications, including but not limited to the following configurations and variations.

For example, the material of the coupling member is not limited to polyacetal, and a thermoplastic resin such as nylon or polycarbonate may be used. Other suitable materials may also be used.

In the above embodiment, the guide is formed on the main body to guide the movement of the engaging member. However, for example, the lower part of the engaging member main body is fitted in the opening and the movement of the engaging member 24 in the direction perpendicular to the forward and backward directions. If you don't have it at all, you don't need a guide.

In addition, in the above embodiment, the pushing means is formed in a ring shape, but it is also possible to form a spiral or a wave shape. It may be formed in other forms.

Further, in the above embodiment, the propulsion means is configured symmetrically with respect to the coupling means in the forward and backward directions, but may be configured asymmetrically if necessary.

Moreover, although the recessed part 14F was provided in the edge of the opening part 14E, it does not need to be provided if it can open and close a cover using a claw.

As described above, although the technical idea of the present invention has been described in detail according to the above-described preferred embodiment, it should be noted that the above-described embodiment is for the purpose of description and not of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
