Description

  The present invention relates to an electronic device mounting plate deflection preventing structure and an electronic device shelf, and more particularly to a structure having a structure in which a plurality of electronic devices can be mounted in a single space.

  Some electronic device shelves have a plurality of electronic devices mounted on one stage, that is, one mounting plate. FIG. 7 is a cross-sectional perspective view (1) of an example of an electronic device shelf according to the prior art. 7, reference numerals 80a and 80b denote electronic devices, 90a and 90b denote mounting plates, 92 denotes a dead space, 93 denotes a support, and 100 denotes an electronic device shelf. FIG. 7 shows a state in which the mounting space for the electronic device is cut horizontally. In addition, for the convenience of explanation, the description that is unnecessary for the explanation of the prior art such as a side panel for supporting the mounting plate is omitted.

  In the electronic device shelf 100 of FIG. 7, the mounting plates 90a and 90b are arranged so as to overlap in the vertical direction, and the whole is held by a side panel (not shown). Then, two electronic devices 80a and 80b can be inserted and mounted in the direction of arrow D per stage. In order to reduce the size of the electronic device shelf 100, it is necessary to make the space around the electronic devices 80a and 80b to be mounted as small as possible and to make the mounting plates 90a and 90b thin. For example, if the support column 93 is present, a dead space 92 that is not useful for mounting the electronic devices 80a and 80b is formed in accordance with the width of the support column 93. Therefore, in order to reduce the size, it is necessary to reduce the width as much as possible. come. This also applies to the case where a bracket having the same action as the support 93 is provided.

  However, the column 93 or the bracket supports the load, and there is a limit to reducing the width of the column 93 or the like with this structure in view of a fixing method or the like.

  FIG. 8 is a cross-sectional perspective view (2) of an example of an electronic device shelf according to the prior art. In FIG. 8, 80 is an electronic device, 91 is a front panel, 94a and 94b are partition plates, 97 is a back panel, and other symbols are the same as those used in FIG. FIG. 9 is a cross-sectional perspective view (3) of an example of an electronic device shelf according to the prior art. In FIG. 9, 99a and 99b are openings, 94a and 94b are partition plates, 95a, 95b and 96 are locking parts, 97 is a rear panel, and 98 is an opening, and the other symbols are the symbols used in FIG. Indicates the same thing. In FIG. 8 and FIG. 9, for the convenience of explanation, description unnecessary for explanation of the prior art such as a column supporting the mounting plate is omitted.

  The electronic device shelf 100 shown in FIG. 8 can also have a plurality of electronic devices mounted in one stage, similar to the one shown in FIG. In this shelf, the front and rear partition plates 94a and 94b have the same function as the support column 93. In this case, it is possible to prevent the mounting plates 90a and 90b from being bent even if the dead space is somewhat narrowed. However, in order to hold the partition plates 94a and 94b in a state that can withstand the load from the electronic device, it is necessary to fix the front and rear ends thereof to the front panel 91 and the back panel 97. Therefore, a dead space is generated by the width of the fixed portion of the partition plates 94a and 94b.

  In the structure using the partition plate, as shown in FIG. 9, for example, locking portions 95a and 95b and a locking portion 96 are formed on the partition plate 94b, and the openings 99a and 99b of the mounting plate 90b, respectively, and the rear panel There are also those that engage with 97 openings 98. In this structure, since it is not necessary to fix the partition plate 94b to the front panel 91, the width of the dead space is only the thickness of the partition plates 94a and 94b. However, in this structure, the locking portions 95a and 95b protrude below the mounting plate 90b. Therefore, in order to secure a space for the portion protruding downward, it is necessary to widen the distance between the mounting plate 90a and the mounting plate 90b by a width corresponding to this. In the end, this still creates new dead space.

Therefore, even when a space for mounting an electronic device is partitioned by a partition plate, a structure for holding the partition plate at two or more locations on the upper, lower, left, and right sides of the partition plate is required (see, for example, Patent Document 1). ), Whichever side is provided is a factor that hinders downsizing of the electronic device shelf.

Things to do It was.

  Therefore, the present invention is slightly inferior to the other means in terms of downsizing the electronic device shelf because the support body protrudes above the top plate and below the lowermost electronic device mounting plate. Since it is not necessary to form a locking portion on the device mounting plate, the electronic device mounting plate can be easily manufactured.

  In the present invention, since the electronic device mounting plate itself has a structure for supporting the load and weight of the electronic device, the dead space can be greatly reduced, and the electronic device shelf can be easily downsized. As a result, it is possible to reduce the installation space for the electronic device shelf.

  In the present invention, the electronic device mounting plate itself is pre-made with an opening for supporting the locking portion and the other mounting plate, and the load and weight of the electronic device are supported by the locking portion and the opening. The biggest feature is that it is possible to prevent deflection. Hereinafter, embodiments having this feature will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view showing a deflection preventing structure for an electronic device mounting plate according to a first embodiment of the present invention. In FIG. 1, 10 is a mounting plate, 11 is a locking portion, 12 is a recess, 13 is an opening, 14 is a bent end, 15 is a screw hole, 20 is a mounting plate, 21 is a locking portion, and 22 is a recess. , 23 is an opening, 24 is a bent end, 25 is a screw hole, 80a and 80b are electronic devices, and 81a and 81b are front panels.

  The deflection preventing structure of FIG. 1 is an exploded view of a part of a shelf for electronic equipment, and the mounting plates 10 and 20 are mounting plates that are adjacent to each other in the vertical direction. The electronic devices 80 a and 80 b are inserted between the mounting plate 10 and the mounting plate 20 along the directions of arrows A and B, and are mounted on the mounting plate 20. In addition, when the electronic devices 80a and 80b are mounted on the mounting plate 20, a slight gap is formed except for the front panels 81a and 81b.

  The mounting plate 10 has an opening 13 on the front side and a locking portion 11 on the rear side. The opening 13 and the locking portion 11 are formed at the same position as a slight gap formed between the mounted electronic devices 80a and 80b when viewed in plan (when the electronic device shelf is viewed from above). Yes. The opening 13 has the engaging portion 21 of the mounting plate 20 inserted therein, and the recessed portion 22 of the engaging portion 21 is fitted to the rear side thereof. The locking portion 11 is formed by cutting out a part of the mounting plate 10 and bending it upward. Further, the bent locking portion 11 is parallel to the directions of the arrows A and B, and when viewed from the front of the mounting plate 10, there is only a width of the thickness of the mounting plate 10. Furthermore, a recess 12 is formed in the locking portion 11 and is fitted into an opening of another mounting plate (not shown) located above the mounting plate 10. The left and right bent ends 14 are screwed to the side panel (not shown) using screw holes 15.

  The mounting plate 20 has a locking portion 21 on the front side and an opening 23 on the rear side. Therefore, the positional relationship between these front and rear is opposite to that of the mounting plate 10. Further, the locking portion 21 and the opening 23 are also formed at the same position as a slight gap formed between the mounted electronic devices 80a and 80b. Furthermore, the locking portion 21 is also parallel to the directions of the arrows A and B, and when viewed from the front of the mounting plate 20, there is only a width of the thickness of the mounting plate 20. The concave portion 22 of the locking portion 21 is fitted into the opening 13 of the mounting plate 10 as described above. The opening 23 is fitted into a concave portion of a locking portion of another mounting plate (not shown) located below the mounting plate 20. The left and right bent ends 24 are screwed together with the mounting plate 10 to the side panel (not shown) using screw holes 25.

  Therefore, in this structure, the mounting plate 20 is locked to the mounting plate 10 positioned above by the locking portion 21 formed at the center thereof, and the mounting plate 10 is further related to the mounting plate located above the mounting plate 10. It has a chained locking structure that stops. Further, a top plate is formed above these mounting plates, and this top plate also has a locking structure. Accordingly, there is a gap corresponding to the thickness of the mounting plate between the mounted electronic devices, and the uppermost mounting plate can be locked further above the uppermost mounting plate. Since the mounting plate and the top plate to be described later can hold a load from the electronic device, the deflection of these mounting plates can be prevented. Further, since the mounting plate 10 and the mounting plate 20 are fixed to other members at the left and right bent end portions 14 and the bent end portion 24, respectively, the locking portion 11 or the locking portion with a slight degree of stress. 21 will not come off.

  The above structure has been described on the assumption that all the mounting plates and the top plate share and hold the load from the electronic device. However, the top plate has rigidity to support most of the load from the electronic device. If the mounting plate has such a rigidity that it does not bend when it is lifted from the top plate, the mounting plate can be prevented from being bent. Moreover, it is also possible to hold with other structures such as a beam instead of the top plate.

  Moreover, since the latching | locking part 11 and the latching | locking part 21 should just be a shape which can be fixedly hold | maintained with the opening part of the mounting board located above these, for example, it is in other shapes, such as a reverse L type and a T-shape It can also be formed. Further, in the example of FIG. 1, one pair of the locking portion and the opening portion is formed on one mounting plate. For example, when the mounting plate is long in the depth direction, in order to reliably prevent deflection. It is preferable to form two or more pairs of these. Furthermore, in an electronic device shelf in which three or more electronic devices are mounted on one mounting plate, it is preferable to form these in the respective gaps of the mounted electronic devices in order to reliably prevent bending. In addition, the mounting plate 10 and the mounting plate 20 may not be fixed to the side panel, but may be fixed via a support or a bracket.

  If there is no problem in mounting the electronic device, a large number of openings can be formed in the mounting plate 10 and the mounting plate 20 in order to reduce the weight of the electronic device shelf. In addition, a shallow recess or opening may be formed where the legs of the mounted electronic device are located so that the mounting position of the electronic device can be easily determined. In this case, if an opening formed when the locking portion 11 and the locking portion 21 are cut out is used, there is no need to newly form an opening. In addition, if there is a slight gap in the vicinity of the left and right bent ends of the mounting plate 10 and the mounting plate 20 in a state where the electronic device is mounted, this portion is cut out and protruded upward. You may use as a guide at the time of electronic equipment insertion.

  Next, the electronic device shelf having the deflection preventing structure shown in FIG. 1 will be described. FIG. 2 is a perspective view showing an example of an electronic device shelf having the deflection preventing structure shown in FIG. In FIG. 2, 30, 40 and 50 are mounting plates, 60 is a top plate, 63a and 63b are openings, 70a and 70b are side panels, 71 is a screw, and 100 is an electronic device shelf. FIG. 3 is a cross-sectional view showing an example of an electronic device shelf having the deflection preventing structure shown in FIG. In FIG. 3, 31 is a locking part, 32 is a recess, 33 is an opening, 61 is a locking part, and 62 is a protruding part.

  As shown in FIG. 2, the electronic device shelf 100 has the mounting plates 10 to 50 on which the electronic device 80 is mounted and the left and right bent ends of the top plate 60 fixed to the side panels 70a and 70b with screws 71. Yes. As shown in FIG. 3, the top plate 60 is partly cut out and bent toward the mounting plate 10 located at the uppermost stage to form a locking portion 61. Further, a protruding portion 62 is formed at the tip of the locking portion 61. In the example of FIG. 2, two sets of these locking structures are provided in order to distribute and hold the load from the electronic device. In addition, the top plate 60 and the mounting plates 10 to 50 have rigidity to share and support loads from all the electronic devices 80 to be mounted. Further, the locking portion 61 and the locking portion 11 are locked by fitting the protruding portion 62 into the recess 12. Furthermore, the front end portion of the locking portion 11 of the mounting plate 10 is fitted into the groove-like portions of the openings 63 a and 63 b of the top plate 60 and is provided so as not to protrude above the top plate 60.

  Also, the mounting plate is assembled as follows. FIG. 5 is a cross-sectional view showing a method of assembling the mounting plate shown in FIG. In the state shown in FIG. 5, the mounting plate below the mounting plate 30 is fixed to side panels 70a and 70b not shown here. Here, the opening 23 of the mounting plate 20 is aligned with the locking portion 31 of the mounting plate 30. Next, the locking part 31 is inserted into the opening part 23, and when the recess 32 and the opening part 23 are at the same height, the mounting plate 20 is moved in the direction of arrow C to lock the locking part 31 and the opening part 23. Put it in a state. Other mounting plates are similarly assembled and fixed with screws 71.

  As described above, the electronic device shelf 100 supports the load from the electronic device 80 because the top plate 60, the mounting plate 10, and the mounting plates below the mounting plate 20 are locked together. When mounted, the mounting plate will not bend. Further, since the distal end portion of the locking portion 11 is fitted into the groove-like portions of the openings 63a and 63b of the top plate 60, an external force that distorts the electronic device shelf 100 in the lateral direction due to, for example, an earthquake or the like. Even if it adds, since the front-end | tip part of the latching | locking part 11 is hold | maintained semi-fixed, a latching | locking part does not come off. Further, the locking portions 11 to 51 of the mounting plates 10 to 50 and the locking portion 61 of the top plate 60 are all formed in a direction parallel to the insertion direction of the electronic device 80, and Since it stands up at a site that does not hinder mounting, the dead space has a width corresponding to the thickness of the mounting plate (the thickness of the top plate for the uppermost mounting space), and the electronic device shelf 100 can be easily miniaturized. become. In addition, since there is nothing protruding above the top plate 60, it is possible to place an object on the top plate 60.

  In the electronic device shelf 100 shown in FIG. 2, the top plate 60 can support the load from all the electronic devices 80, and the mounting plates 10 to 50 do not bend. It is also possible to have a structure held in

  Furthermore, a description will be given of a deflection preventing structure for an electronic device mounting plate according to a second embodiment of the present invention. FIG. 4 is a cross-sectional view showing a structure for preventing deflection of an electronic device mounting plate according to a second embodiment of the present invention. In FIG. 4, 16 is an engaging part, 17 is a protruding part, 26 is an engaging part, 27 is a protruding part, 36 is an engaging part, and the other reference numerals are the same as those in FIG.

  This embodiment is characterized in that a locking portion similar to the top plate 60 is formed on the mounting plates 10 to 50. For example, in the case of the mounting plate 10, a locking portion 16 that rises on the mounting plate 20 side is formed instead of the opening 13 in FIG. 1. Further, a protruding portion 17 is formed at the distal end portion of the locking portion 16. And the latching | locking part 16 and the latching | locking part 26 of the mounting board 20 are latched, and the mounting board 20 is supported by the mounting board 10 in the suspended state. The same applies to other mounting plates. As a matter of course, since the locking portion 21 is shortened, the opening formed along with the formation of the locking portion 21 is smaller than in the case of FIG.

  This embodiment is particularly useful when it is desired to make the opening portion as small as possible, for example, when the opening portion of the mounting plate 20 is easily caught by a portion protruding from the housing of the electronic device 80 when the electronic device 80 is inserted. Is something. Further, similarly to the locking portion 11 of FIG. 3, since the tip end portion of each locking portion is held semi-fixed, the locking portion does not come off.

  Furthermore, a description will be given of a deflection preventing structure for an electronic device mounting plate according to a third embodiment of the present invention. FIG. 6 is a sectional view showing a structure for preventing deflection of an electronic device mounting plate according to a third embodiment of the present invention. In FIG. 6, 72 is a locking strip, 73a to 73d are recesses, and the other symbols used are the same as those in FIG.

  In this embodiment, instead of forming the locking portion 11 and the like, the locking strip-like plate 72 having a recess 73a and the like are collectively locked. That is, only the opening such as the opening 13 is formed in a portion where the locking portion 11 or the like is formed, and the recess 73a or the like is locked to each opening through the locking strip plate 72.

  Therefore, unlike the other embodiments, the end of the locking strip 72 protrudes from the top surface of the top plate 60 and the bottom surface of the mounting plate 50, so that these surfaces are not flat and the shelf is tall. However, there is an advantage that the structure of the mounting plates 10 to 50 and the top plate 60 is simplified.
