Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stacking structure of electronic device housings for positioning and stacking a plurality of electronic device housings.

[0002]

[Prior art]

 In the case where another unit is positioned and laminated on one unit of an electronic device casing, conventionally, a laminated structure as shown in FIGS. 4 to 6 has been generally used. In FIG. 4, a top plate 2 is fixed to the upper surface of the basic unit 1 with four screws 3. When the additional unit 4 is stacked on the basic unit 1 as shown in FIG. 5, the four screws 3 are removed and the top plate 2 is removed, and then the additional unit 4 is placed on the basic unit 1. Next, the top plate 5 of the additional unit 4 is removed, and the screws 3 are inserted into the mounting holes 7 formed near the four corners of the bottom plate 6 of the additional unit 4 as shown in FIG. The screw 3 is screwed into the screw hole 8 of. Finally, the top plate 5 is attached to the additional unit 4 with screws (not shown).

However, according to the conventional laminated structure of the electronic device housing as described above, the top plates 2 and 5 of the basic unit 1 and the additional unit 4 are removed, and the mounting hole 7 and the screw hole 8 are positioned. Since the screws 3 must be screwed together, there is a problem that it takes a lot of man-hours. In particular, positioning is difficult when stacking large casings.

[0004]

[Problems to be solved by the device]

 As described above, according to the conventional laminated structure of the electronic device housing, there is a problem that it takes a lot of man-hours to fix the laminated units with screws.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a laminated structure of an electronic device housing in which a plurality of units can be easily positioned and laminated.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention according to claim 1 is a laminated structure of an electronic device housing in which a plurality of rectangular parallelepiped housings each having a top plate and a bottom plate are positioned and stacked. The top plate of the housing is provided with a plurality of convex pins so as to be movable up and down, and the bottom plate of the housing on the top is provided with a plurality of recesses into which the convex pins fit. Further, the present invention according to claim 2 is characterized in that a biasing means for biasing the convex pin in the direction of projecting to the upper part of the top plate is provided.

[0007]

[Action]

 According to the above configuration, when the upper case is placed on the lower case, the convex pin is pressed and moves down, but the upper case is slightly displaced and the convex pin is provided on the bottom plate of the upper case. By fitting in the recess, the upper casing can be positioned and laminated with respect to the lower casing.

[0008]

【Example】

 An embodiment of a laminated structure of an electronic device housing according to the present invention will be described below with reference to the drawings.

1 and 2 show the configuration of an embodiment of the present invention. In these figures, the portions corresponding to those of the conventional example shown in FIGS. 4 to 6 are designated by the same reference numerals, and the description thereof will be omitted as appropriate. In the vicinity of the four corners of the top plate 2 of the basic unit 1, convex pins 11 are mounted so as to be vertically movable. A flange 11a is provided at one end of the convex pin 11 projecting from the lower surface of the top plate 2, and the flange 11a is housed in a cylindrical support member 12 provided on the lower surface of the top plate 2 so as to be vertically movable. Has been done. Further, a coil spring 13 as an urging means is provided between the bottom surface of the support member 12 and the collar portion 11a, and urges the convex pin 11 to move upward.

On the other hand, substantially cylindrical recesses 6 a are formed at four corners of the bottom plate 6 of the additional unit 4 at positions facing the convex pins 11 provided on the top plate 2 of the basic unit 1. Then, when the additional unit 4 is placed on the basic unit 1, the convex pin 11 is fitted in the concave portion 6a and positioned and connected. When only the basic unit 1 is used, by attaching a decorative plate (not shown) on the top plate 2, the convex pin 11 can be pushed into the support member 12 to hide it.

According to the present embodiment, by simply mounting the additional unit 4 on the basic unit 1, it is possible to perform positioning and connection by one-touch by the convex pin 11, and workability is improved. By making the convex pin 11 and the concave portion 6a sufficiently long, even if the additional unit 4 is small, the connection between the units can be maintained as long as the additional unit 4 does not fall.

In the above embodiment, the case where the coil spring 13 is used as the biasing means for projecting the convex pin 11 upward has been described, but a leaf spring 14 may be used as shown in FIG. One end of the plate panel 14 is fixed to the top plate 2 via a hook 15, and a convex pin 11 is attached to the other end. A thin portion 14a is formed in the middle of the leaf spring 14 so that it can be easily elastically deformed. The convex pin 11 is urged by the urging force of the leaf spring 14 in a direction projecting from the upper surface of the top plate 2.

According to this embodiment, the same effect as that of the above-described embodiment can be obtained. In each of the above-described embodiments, the case where two units 1 and 14 are stacked has been described, but the present invention can be applied to the case where three or more units are stacked. Further, the numbers of the convex pins 11 and the concave portions 6a are not limited to four.

[0014]

[Effect of device]

 As described above, according to the laminated structure of the electronic device housing of the present invention, the convex pin is provided on the top plate of the lower housing so as to be movable up and down, and is fitted in the recess of the bottom plate of the upper housing. Therefore, a plurality of casings can be easily positioned and laminated.
