JP6408208B2 - Housing with anti-tip foot - Google Patents

Description

  The present invention relates to a fall prevention foot and a case with a fall prevention foot.

  In recent years, electronic devices such as desktop computers and servers have been rapidly reduced in size and thickness. In order to further reduce the installation space, the introduction of a design that enables vertical installation is also in progress. When the electronic device is placed vertically, it is necessary to provide a foot for preventing the fall. However, when a plurality of such devices are arranged adjacent to each other, there is a problem that the fall prevention feet interfere with each other and the interval cannot be reduced.

  A technique for solving such a problem is disclosed in Patent Document 1, for example. In this technique, the fall-preventing feet projecting to the left and right of the housing are arranged shifted in the depth direction. In this way, when the casings come close to each other, the adjacent fall-preventing feet do not interfere with each other, and the feet sink into the space under the adjacent casing. For this reason, a plurality of housings can be arranged close to each other.

JP 2003-108261 A

  However, the technique of Patent Document 1 has a problem that the interval between adjacent housings can be reduced, but the interval cannot be adjusted when a predetermined interval is required.

  In order to solve the above-described problems, in the present invention, there is provided a fall-preventing foot used in a housing having a support member provided at a predetermined position on the bottom surface and having a space between the installation surface and the bottom surface. Mounted on the bottom surface of the casing in the first rectangular parallelepiped region that is positioned, the width is narrower than the first rectangular parallelepiped region, contacts the installation surface, and can slide outward from the first casing side surface of the casing A first stopper, a first stopper provided on an opposite side of the first rectangular parallelepiped region to the first foot, and preventing an object from entering the first rectangular parallelepiped region; A second rectangular parallelepiped region adjacent to one rectangular parallelepiped region is attached to the bottom surface of the casing and is narrower than the second rectangular parallelepiped region and is in contact with the installation surface and opposite to the side surface of the first casing. A second foot that is slidable outward from the side surface of the second housing; And said second leg portion of the second rectangular region has a second stopper that inhibits the objects from entering the provided opposite the second cuboid region.

  The effect of the present invention is that when a plurality of casings having fall prevention feet are arranged, the interval can be adjusted to a desired value.

FIG. 1 is a perspective view showing an example in which the fall prevention foot of the present embodiment is applied to a housing. One fall prevention foot 2 from the bottom of the housing 1 extends to the outside of the side surface of the housing 1 to support the housing. The left and right fall prevention feet 2 are arranged shifted in the depth direction.

  FIG. 2 is a perspective view showing the fall prevention foot 2 of the present embodiment. The figure is viewed from the ground side when attached to the bottom surface of the housing. Two feet 3 are attached to a crank-type base 4. Here, as shown in FIG. 2, a rectangular space including one crank extending portion and the foot 3 is defined as a first rectangular solid 100, and a space including the other extending portion and the foot 3 is defined as a second rectangular parallelepiped 200.

  Here, attention is focused on the first rectangular parallelepiped 100. Within the rectangular parallelepiped, the foot 3 is fitted to the crank extension of the base 4 so as to be slidable in the extension direction. A stopper 4 a is provided at the end opposite to the foot 3.

  The configuration in the second rectangular parallelepiped is the same as the configuration in the first rectangular parallelepiped 100, and the direction is opposite.

  The foot part 3 is provided with a grip part 3a so as to embrace the extended part of the crank. Further, a rubber foot 3b for contacting the ground is provided near the outer end of the foot 3 in the outward direction. Further, on the side close to the center of the crank, there is provided a groove 3c that penetrates the foot 3 in the thickness direction and extends in parallel with the extending direction of the crank. The foot 3 is locked to the base by a screw 6 that passes through the groove 3c and is screwed to the base 4. When the screw 6 is loosened, the foot 3 can slide along the groove 3c, and is fixed when tightened. The screw 6 may be a rivet or an elastic body as long as it can be fixed and relaxed.

  FIG. 3 is a perspective view showing details of the fall prevention foot 2. The foot part 3 is inserted so that the guide part 4b of the base 4 fits into the grip part 3a. The screw 6 is screwed into the screw hole 4c provided in the base 4 through the groove 3c. The base 4 is fixed to the bottom surface of the housing 1 by fixing the base fixing tool 5 to the bottom surface of the housing through the base fixing hole 4d.

  FIG. 4 is a side view showing the housing 1 to which the fall prevention foot 2 is attached. Rubber feet 7 are attached to the bottom of the housing 1 at four corners, and a space is formed between the bottom 1 a and the floor 8. The first cuboid 100 and the second cuboid 200 are arranged in this space. The foot 3 is visible on the first cuboid 100 side, and the stopper 4a is visible on the second cuboid 200 side. Rubber feet 3 b attached to the feet 3 are in contact with the floor surface 8.

  Next, the operation of the foot 3 will be described. FIG. 5 is a plan view showing the operation. Rubber feet 7 are provided at the four corners of the bottom surface 1 a of the housing 1. The foot 3 can be slid with respect to the base 4 when the screw 6 is loosened. When the fall prevention foot 2 is not used, for example, when stored, the right foot portion 3R and the left foot portion 3L are retracted from the side surface of the housing 1 as shown in FIG. When using the fall prevention foot 2, loosen the screw 6 and pull out the right foot 3R and left foot 3L to the outside of the bottom surface 1a by the desired length as shown in FIG. To do.
