JP 2002-368443 A

  However, in the technique described in Patent Document 1, a hinge must be used, which increases the number of parts and causes an increase in cost.

  An object of this invention is to provide the apparatus housing | casing which can open and close a lid | cover, without using a new component.

The device housing of one embodiment of the present invention includes first and second metal panels. The first and second metal panels are disposed to face each other with a space therebetween, and each has first and second longitudinal edges that face each other. On one end side of each of the first and second metal panels, a shaft portion is formed by burring so as to protrude inward. A lid panel is disposed across one end of the first and second metal panels. A closed state in which at least a portion between the one end portions of the first and second metal panels is closed and an open state in which the at least a portion is opened are supported on the outer peripheral surface of the shaft portion. .

  In the device casing configured as described above, the lid panel is rotatably supported by the shaft portion, and thus can be in either an open state or a closed state. Since the shaft portion is formed by burring the first and second metal panels, it is not necessary to prepare parts for the shaft portion, and the cost can be reduced. Further, since the first and second metal panels are bent, the lid panel can be supported on the shaft portion by utilizing this bending, and the mounting work can be easily performed.

  The lid panel can have a plate-like body in which an opening is formed in a state of being in surface contact with one end of each of the first and second metal panels. In this case, each shaft portion is inserted into each opening, and the lid panel is rotatably supported.

  In this way, the lid panel is configured so that the opening formed in the plate-like body in surface contact with one end of the first and second metal panels is inserted through the shaft portion. It becomes easy.

In the closed state, the lid panel has a linear portion extending from the other end side of the first longitudinal edge of the first and second metal panels to the one end side, and the linear portion And an inclined portion inclined toward the one end portion in the second longitudinal edge direction from the tip.

  When configured in this manner, for example, when a connecting tool for connecting to, for example, an electric circuit in the device casing is provided on the inclined portion, connection to these connecting tools can be easily performed in the closed state.

Further, the first and second metal panels are arranged such that the second longitudinal edge is a linear portion that is non-parallel to the linear portion of the first longitudinal edge, and the second longitudinal edge is substantially horizontal. And when the said cover panel is made into the said open state, the stopper which prevents rotation of the said inclination part can also be provided in the said inclination part in the state in which the said inclination part became substantially horizontal.

  When configured in this way, when the linear portion is maintained outside the one end of the first and second metal panels, and components are arranged on the inner surface of the linear portion, The maintenance inspection can be performed easily. Moreover, since the stopper receives the weight of these parts, a large force is not applied to the shaft portion, and the shaft portion is not easily damaged.

  Alternatively, female screws are engraved on the inner circumferential surface of each shaft portion, and the first and second rack panels arranged on the outer surfaces of the first and second metal panels are screwed into the first and second screws. It can also be fixed to other metal panels.

If comprised in this way, a shaft part can be commonly used for fixation to the 1st and 2nd metal panel of a rack panel, and fixation to the 1st and 2nd metal panel of a lid panel, For fixing the rack panel to the first and second metal panels, it is not necessary to separately perform burring processing to form the protrusions, and the manufacturing is facilitated.

  A deflection preventing body having higher rigidity than the first and second metal panels can be provided on the outer surfaces of the first and second metal panels. As a bending prevention body, it is possible to use other ones attached to the first and second metal panels, for example, a rack panel for attaching to the rack, and an armrest used for arranging on the table. it can.

  By providing the bend preventing body in this manner, the first and second metal panels can be prevented from being bent when a slight force is applied, and the lid panel can be prevented from being easily detached from the shaft portion.

  As described above, according to the present invention, the lid panel can be attached so as to be freely opened and closed without increasing the number of parts.

  The device housing according to the embodiment of the present invention is, for example, an electronic device, specifically an acoustic adjuster, more specifically an audio mixer housing 2, and is attached to the rack 4 as shown in FIG. Or arranged on the table 6 as shown in FIG. In FIG. 3, the operation unit such as the fader of the audio mixer is omitted. When arranged on the table 6, armrests may be attached to both sides of the housing 2.

  The housing 2 is made of metal and has a rectangular front panel 8 provided with an operation unit as shown in FIG. First and second metal panels, for example, side wall panels 10 and 12 are provided at both ends of the longitudinal edge of the front panel 8 so as to be orthogonal to the front panel 8. The side wall panels 10 and 12 have the same shape and relatively small rigidity. Although not shown, a printed circuit board on which an audio mixer circuit is configured is arranged on the surface of the front panel 8 on which the side wall panels 10 and 12 are attached.

  As shown in FIG. 4, the side wall panel 10 has a first longitudinal edge, for example, a straight edge 14 that coincides with the end of the longitudinal edge of the front panel 8. A bottom wall panel 16 is provided so as to be orthogonal to the front panel and the side wall panels 10 and 12 from one end of the edge portion 14. The front end is bent to the front panel 8 side in parallel with the front panel 8 to form a plate-like portion 18. Further, an upper wall panel 20 is provided at the other end of the front panel 8 so as to be orthogonal to the front panel 8 and the side wall panels 10 and 12. The tip of the upper wall panel 20 is located farther from the front panel 8 than the tip of the bottom wall panel 16.

  The side wall panel 10 has, as a part of the second longitudinal edge, a hypotenuse 22 that is inclined in a direction away from the front panel 8 from the front end of the front panel 20, and the bottom wall of the front panel 8 from the front end of the hypotenuse 22. It has a hypotenuse 24 that is sharply inclined toward the panel 18 side, and has a straight side 26 extending in parallel to the front panel 8 from the tip of the hypotenuse 24 to the tip of the bottom wall panel 18. The second longitudinal edge is constituted by the oblique sides 22 and 24 and the straight side 26. The portions corresponding to the oblique sides 22 and 24 and the straight side 26 in the side wall panel 12 are referred to as the oblique sides 22 and 24 and the straight line 26.

  In order to make the oblique sides 22 and 24 and the straight sides 26 of the side wall panels 10 and 12 into a closed state as shown in FIG. 5 or an open state as shown in FIGS. , 12 is provided with a lid panel, for example, a back panel 28. The back panel 28 includes a gently inclined surface portion 30 that closes between the oblique sides 22 of the sidewall panels 10 and 12, a steeply inclined surface portion 32 that closes between the oblique sides 24 of the sidewall panels 10 and 12, and a straight side 26 of the sidewall panels 10 and 12. It consists of a closed flat portion 34.

  A plate-like portion 36 is formed at each end of the flat portion 34 on the side wall panel 10, 12 side so as to be orthogonal to the flat portion 34. These plate-like portions 36 are formed with openings 38 penetrating in the thickness direction of the side wall panels 10 and 12. In either the closed state where the back panel 28 is closed as shown in FIG. 5 or the open side as shown in FIG. 1 or FIG. A shaft portion 40 inserted through the opening 38 is formed on the inner surfaces of the side wall panels 10 and 12. These shaft portions 40 are formed by burring as shown in FIG. Since the shaft portion 40 is formed by burring, it is not necessary to prepare a separate component for the shaft portion 40. Since the back panel 28 is rotatable around the shaft portion 40, the housing 2 can take either the closed state or the open state described above. In order to be able to rotate, it is necessary to insert each shaft portion 40 through each opening 38, but the side wall panels 10 and 12 are made of metal having relatively small rigidity, so that they can be easily bent and inserted easily. Can be done. Further, since the openings 38 are formed in the plate-like portions 36 provided at both ends of the back panel 38 so as to be orthogonal to the back panel 38, the plate-like portions 38 are brought into surface contact with the side wall panels 10, 12 to form the openings 38. What is necessary is just to insert the axial part 40, and the attachment of the back panel 28 is easy.

  In the open state shown in FIG. 4, the steeply inclined surface portion 32 of the back panel 28 is provided with rotation preventing means, for example, a stopper 42, which contacts the plate-like portion 18 and prevents further rotation of the back panel 28. . The stopper 42 is a protective member provided around the power supply inlet 44 formed in the steep slope portion 32 as shown in FIG. Although not shown, a printed circuit board and parts constituting a part of the circuit of the audio mixer are attached to the inner surface of the gentle slope portion 30 of the back panel 28. As a result, when the back panel 28 is further rotated in the open state, the stopper 42 prevents the rotation of the back panel 28 at a position where the housing 2 may fall due to the position of the center of gravity of the back panel 28. Is formed. Further, the stopper 42 also prevents the steep slope portion 32 and the plate-like portion 18 from coming into direct contact with each other and the steep slope portion 32 or the plate-like portion 18 being damaged.

  As shown in FIG. 5, various connecting tools 46, 48, 50, 52 are provided on the gentle slope portion 32 in addition to the power inlet. For example, as shown in FIG. 3, when the housing 2 is arranged on the table 6 with the back panel 28 in contact with the table 6, and the mixer man of the audio mixer is located on the top panel 20 side, In order to facilitate connection to each connection tool 46, 48, 50, 52, each connection tool 46, 48, 50, 52 is provided on the gentle slope portion 32.

  When the casing 2 is attached to the rack 4 as shown in FIG. 2, as shown in FIGS. 1, 4, and 5, rack panels 54 and 56 are provided on the outer surface side of the side wall panels 10 and 12, as shown in FIG. Are attached by screws 58, 58, 58... These rack panels 54 and 56 are fixed to the rack 4. In this case, the side wall panels 10 and 12 are provided with screw portions for forming internal threads of separate sleeve-like portions formed by burring by female screws 58, 58, 58.

  When fixing the rack panel, as shown in FIG. 7, a female screw is formed on the inner peripheral surface of the shaft portion 40, a through hole is formed in the rack panels 54 and 56, and the male screw 60 inserted therethrough is formed. The rack panels 54 and 56 may be attached to the side wall panels 10 and 12 by being screwed into the female screws. In this case, there is no need to provide a separate female thread portion as described above, and the shaft portion 40 can also be used for mounting the rack panels 54 and 56.

  The rack panels 54 and 56 have greater rigidity than the side wall panels 10 and 12 and are not easily bent by human power. As described above, since the side wall panels 10 and 12 are bent by applying a slight force, the opening 38 of the plate-like portion 36 of the back panel 28 can be easily attached to the shaft portion 40. However, in this state, even if a slight force is mistakenly applied to the side wall panels 10, 12, the shaft portion 40 may come out of the opening 38. Therefore, rack panels 54 and 56 having high rigidity are attached to the outer surfaces of the side wall panels 10 and 12. After the rack panels 54 and 56 are attached, the side wall panels 10 and 12 are difficult to bend even if a considerable force is applied, and the shaft portion 40 can be reliably prevented from coming out of the opening 38 of the plate-like portion 36. In addition, when arranging the housing | casing 2 on the table 6, as mentioned above by making the armrest attached to the outer side of the side wall panels 10 and 12 have rigidity much larger than the side wall panels 10 and 12. Similarly, the shaft portion 40 can be reliably prevented from coming off from the opening 38 of the plate-like portion 36.

  In the above-described embodiment, the oblique side 22 is formed on the side wall panels 10 and 12, but it may be a straight side parallel to the front panel 8 instead. In this case, the gentle slope portion 30 of the back panel 28 is also a flat plate portion parallel to the front panel 8. In the above embodiment, the bottom wall panel 16 is provided, but it may be removed to form a flat portion parallel to the front panel 8 at the tip of the flat portion 34 of the back panel 28.
