The work table 1 can be temporarily installed on the support column 21 by locking each of the protruding body 12 and the bowl-shaped portion 13 to each of the square holes 211. Examples of the protruding body 12 and the bowl-shaped portion 13 will be described in detail in the following embodiments. Since the mounted device 3 and screws and tools necessary for the mounting can be temporarily placed on the work table 1, the mounting of the mounted device 3 on the rack 2 is facilitated.

<First embodiment>
In the first embodiment, the top plate and the support portion are separate bodies. FIG. 2 is an example of a perspective view of the work table of the first embodiment. FIG. 3 is an example of a top view of the top board. FIG. 4 is an example of a front view of the top board. FIG. 5 is an example of a side view of the support portion.

  The work table 1A includes a top plate 10A, a support portion 11A, a projecting body 12A, and a bowl-shaped portion 13A.

The top plate 10 </ b> A includes a mounting portion 101 and a support receiving portion 102. The mounting part 101 is plate-shaped and includes a first mounting part 101-1 and a second mounting part 101-2. The width W1 of the first mounting unit 101-1 is smaller than the width W2 of the second mounting unit 101-2. More specifically, the width W1 is smaller than the dimension between the strut 21 (the dimension in FIG. 2 _{W L).} Specifically, for example, in the case of the work table 1A used for the rack 2 conforming to the EIA standard, the width W1 is less than about 450.8 mm. By comprising in this way, the 1st mounting part 101-1 (projection part) can be made to protrude inside the rack 2. FIG. The upper surface of the first mounting part 101-1 and the upper surface of the second mounting part 101-2 are configured without a step and form a horizontal part 101h.

  Each of the pair of support receiving portions 102 is formed such that a plate-like body is bent at a substantially right angle. For the sake of explanation, here, one end of the support receiving portion 102 is a portion 102-1, a portion bent substantially at a right angle is a portion 102-2, and the other end is a portion 102-3. The part 102-1 is connected to the end of the second mounting part 101-2. The horizontal portion 102h, which is an area between the portion 102-2 and the portion 102-3, is configured so that the horizontal portion 102h is positioned below the horizontal portion 101h in substantially parallel to the horizontal portion 101h. A through hole 103 is formed in the horizontal portion 102h. Although the number of through-holes 103 may be singular or plural, here it is assumed that there are a plurality of through-holes 103.

  Here, the position in the height direction of the horizontal portion 102h is shown as an example below the horizontal portion 101h, but the position in the height direction is not limited to this and is above the horizontal portion 101h. It may be the same or substantially the same. However, by setting the horizontal portion 102h below the horizontal portion 101h, it is possible to prevent an operator, the mounted device 3, wiring, and the like from being caught by a protruding structure such as a locking portion 111, which will be described later, during work such as mounting. be able to.

  The top plate 10A is provided with at least a pair of protrusions 12A. The interval between the pair of projecting bodies 12A is substantially the same as the interval between the two support columns 21. The shape of the protruding body 12A is not limited, but is formed so as to be inserted into the square hole 221. Such a projecting body 12A is provided so as to project in the direction of the square hole 211 from the top plate 10A.

  More specifically, the protrusion 12A preferably has a flat surface on at least one of the upper side and the lower side that can contact the square hole 221. By configuring in this way, the work table 1A can be securely locked to the support column 21. In the figure, an example in which the protruding body 12A is a rectangular parallelepiped is shown, and it is assumed that a surface 121 is formed as a horizontal plane above the rectangular parallelepiped.

  Further, the number of protrusions 12A to be locked to one support column 21 is not limited and may be plural, but from the viewpoint of workability in assembling to the rack 2, an example of one is shown here. Yes.

  Further, here, the surface 121 is configured to be positioned above the horizontal portion 102h. However, the surface 121 is not limited to this, and may be the same as the horizontal portion 102h, and below the horizontal portion 102h. There may be. Further, the positional relationship between the surface 121 and the horizontal portion 101 h may be the same or different, but here, a different case is shown, and more specifically, the horizontal portion 101 h is positioned above the surface 121. An example of the case will be described.

  The support portion 11A includes a horizontal portion 11h and a vertical portion 11v, and is configured so that the horizontal portion 11h and the vertical portion 11v are substantially perpendicular. Here, the support portion 11A is an example in which a part of the support portion 11A is a plate having a substantially right angle. However, the support portion 11A is not limited thereto, and may be, for example, a so-called L-shape. The horizontal portion 11 h is provided with a locking portion 111 so that it can be locked to the through hole 103. The vertical portion 11v is provided with a hook-shaped portion 13A so as to be locked in the square hole 211.

  Although the number of the latching | locking parts 111 is not specifically limited, Here, the example in which the some latching | locking part 111 is provided is shown. Below, when distinguishing especially, the latching | locking part 111 provided in the furthest position from the hook-shaped part 13A is made into the latching | locking part 111-1, and others are demonstrated as the latching | locking part 111-2. The locking portion 111-1 is configured to protrude obliquely from the horizontal portion 11 h toward the rack 2. In addition, about the latching | locking part 111-1, it is more preferable if it forms with an elastic body like a leaf | plate spring, for example.

  The locking portion 111-2 is formed so that the plate-like body is bent at a substantially right angle. For the sake of explanation, here, one end of the locking portion 111-2 is a portion 111-21, a portion where the plate-like body is bent at a substantially right angle is a portion 111-22, and the other end is 111-23. The part 111-12 is connected to the horizontal part 11h. The horizontal portion 111h, which is a region between the portion 111-22 and the portion 111-23, is configured to be substantially parallel to the horizontal portion 11h and project in the opposite direction of the rack 2. By doing in this way, it becomes possible for the latching | locking part 111-2 to suppress the motion to the rack 2 direction of 10 A of top plates, and the motion to the up-down direction of 10 A of top plates.

  The number of the hook-shaped portions 13A is not limited and may be singular or plural, but here, an example is shown in which two hook-shaped portions 13A are provided on one support 11A. The hook-shaped portion 13A is formed as if the plate-like body is bent at a substantially right angle. For the purpose of explanation, here, one end of the hook-shaped portion 13A is a portion 13-1, a portion where the plate-like body is bent at a substantially right angle is a portion 13-2, and the other end is 13-3. The part 13-1 is connected to the vertical part 11v. The vertical portion 13v, which is a region between the portion 13-2 and the portion 13-3, is configured to be substantially parallel to the vertical portion 11v and protrude downward. By doing in this way, it becomes possible to hook 13A of hook-shaped parts in the square hole 211. FIG.

  In addition, about the latching of the work bench | platform 1A to the support | pillar 21, after locking the support part 11A to the support | pillar 21 previously, the top plate 10A is locked to the support | pillar 21 and the support part 11A so that a detail may mention later. However, the present invention is not limited to this, and after combining the top plate 10A and the support portion 11A in advance, the two may be simultaneously locked to the support column 21.

  FIG. 6 is a schematic cross-sectional view when the work table is locked to the support column. In addition, in FIG. 6, the cross-sectional schematic diagram in line S1-S1 part of FIG. 3 is shown.

  As shown in FIG. 6A, the hook portion 13 </ b> A is hooked in the square hole 211 by moving the support portion 11 </ b> A. Thereby, the support portion 11 </ b> A can be locked to the support column 21. Next, as shown in FIG. 6 (B), the through-hole 103 of the top plate 10A is passed through the engaging portion 111 of the support portion 11, and the top plate 10A is attached to the rack 2 as shown in FIG. 6 (C). Slide towards. As a result, as shown in FIG. 6D, the locking portion 111 can be locked in the through hole 103, and the protruding body 12 </ b> A can be passed through the square hole 211.

  The position of the projecting body 12A in the height direction is the position of the through hole for fixing (for example, the through hole 31 in FIG. 1) to the rack 2 in the mounted device 3 when the mounted device 3 is placed on the top plate 10A. A square hole 211 for locking the fixing through hole (for example, the square hole 211A in FIG. 1) is configured to be the same or substantially the same. Therefore, here, an example in which the horizontal portion 101h is positioned higher than the surface 121 as described above is shown, but the present invention is not limited to this. Depending on the positional relationship in the height direction between the horizontal portion 102h and the horizontal portion 101h, the horizontal portion 101h may be positioned below the surface 121, and the surface 121 and the horizontal portion 101h may be the same or substantially the same. . The position of the surface 121 in the height direction, in other words, the position of the protrusion 12 in the height direction is for locking the position of the through hole for fixing to the rack 2 of the mounted device 3 and the fixing through hole. It is preferable that the rectangular holes 211 are configured to be at the same or substantially the same position. Needless to say, the hook-shaped portion 13A is also configured so as to have the above positional relationship. As a result, it is possible to perform a locking operation such as screw fastening to the support column 21 and the fixing through-hole while the mounted device 3 is placed on the top plate 10A on the top plate 10A, and the workability is further improved. .

  Further, the depth dimension (for example, dimension d in FIG. 6D) of the projecting body 12A may be made longer than a predetermined value to function as a guide in the operation as shown in FIG. 6B. This predetermined value can be determined from the thickness of the top plate 10A, the size and position of the locking portion 111, and the like.

  In this embodiment, since the top plate 10A and the support portion 11A are separate bodies, even a weak operator can easily assemble the rack 2. Moreover, since the top plate 10A and the support portion 11A can be separated, the storability and transportability are also improved.

<Second embodiment>
In the second embodiment, the top plate 10 and the support portion 11 are integrated. Hereinafter, only portions different from the first embodiment will be described in detail.

  FIG. 7 is an example of a perspective view of the work table 1 of the second embodiment. FIG. 8 is an example of a schematic cross-sectional view taken along line S2-S2 in FIG.

  The work table 1B includes a top plate 10B, a support portion 11B, a projecting body 12B, and a bowl-shaped portion 13B. The top plate 10B has a linear motion mechanism 104 that linearly moves the protrusion 12B. In the drawing, an example is shown in which the linear motion mechanism 104 is realized by a slider formed by a combination of a cylindrical portion and a sliding portion having an outer diameter smaller than the inner diameter of the cylindrical portion. The linear motion mechanism 104 includes a handle 104-1. The operator can move the protrusion 12B directly by holding the handle 104-1 and moving it horizontally (see the arrow in FIG. 8).

  In addition, the technique which implement | achieves the linear motion mechanism 104 is not specifically limited, In addition to the above, you may implement | achieve, for example with a gear, a screw, or these combination. Although not shown here, a lock mechanism that locks the linear motion of the linear motion mechanism 104 may be provided. The technique for realizing the lock is not particularly limited, but may be realized by, for example, a gear, a screw, a hook, a pin, or the like.

  Regarding the locking of the work table 1B to the support column 21, first, the hook 13B is passed through the square hole 211 of the support column 21, and then moved downward to be locked. Next, the protruding body 12 </ b> B is inserted into the square hole 211 by moving linearly in the direction of the column 21.

  The support portion 11B may be configured to be foldable with respect to the top plate 10B. For that purpose, for example, a hinge or a stay may be provided so as to connect the support portion 11B and the top plate 10B. Accordingly, the support portion 11B can be tilted in the direction indicated by the arrow D in FIG. 7 or in a direction substantially perpendicular to the arrow D, and the top plate 10B and the support portion 11B can be configured to be substantially parallel. By doing in this way, the space-saving property of the workbench 1B can be improved.

  In this embodiment, it becomes easy to insert the protruding body 12 </ b> B into the square hole 211 of the column 21. Moreover, since the top plate 10B and the support part 11B are integrated, there is no loss of these and management becomes easy.

<Third embodiment>
The top plate 10 of the first embodiment and the second embodiment can have a structure for preventing a screw from falling off.
FIG. 9 is a diagram for explaining an example of a configuration for preventing the screw from falling off. In FIG. 9, for simplification, a part of the work table is omitted.

  A wall-like portion 105 is provided on at least a part of the edge of the top plate 10C. FIG. 9 shows an example in which the wall-like portion 105 is not provided in a part of the front portion of the top plate 10C. Thereby, the operation | work which mounts the mounting apparatus 3 on the top plate 10C becomes easy.

  An elastic portion 106 is provided near both ends of the top plate 10C, and a concave portion 107 is provided near the front of the top plate 10C.

  The elastic portion 106 is, for example, anisotropic rubber, and may be an elastic body having a magnetic force. The upper surface of the elastic portion 106 is configured to have the same or substantially the same surface height as the horizontal portion 101h. However, the present invention is not limited to this, and the elastic portion 106 may protrude upward or downward with respect to the horizontal portion 101h.

  An elastic body having a magnetic force is provided at the bottom of the concave portion 107 in the same manner as the elastic portion 106 described above. It is more effective if the concave portion 107 is provided in the vicinity of a place where the wall-shaped portion 105 is not present.

  As a result, it is possible to prevent the tools, mounters, screws, and the like necessary for mounting the mounted device 3 from falling. In particular, it is effective in preventing metal parts such as screws that may cause a short circuit from falling. The work table need not include all of the wall-shaped portion, the elastic portion, and the concave portion, and may include only a part.

  The work table of the present embodiment is configured as described above. By hooking the hook-like part into the square hole of the support and further passing the rectangular parallelepiped through the square hole, even if there is no configuration such as a rail, it is possible to work with a mounted device or tool. In addition, since the work table is locked to the support column by the bowl-shaped portion and the rectangular parallelepiped, even a relatively heavy mounted device can be stably placed temporarily.

  In addition, since the first mounting part, which is a part of the top plate, is configured to protrude to the inside of the rack, it is not necessary to support the mounting device with a hand or the like from below during locking work such as screw fastening, Mounting work becomes easier.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
