DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a cabinet 1 (storage fixture) as a first embodiment of the present invention. I have. The cabinet 1 has a main body portion 5 formed in a box shape having an open front surface by two side plates (not shown), a top plate 3, a bottom plate 4, and a rear plate (not shown), and a side plate of the main body portion 5. And a unit cover 2 attached so as to cover the main body 5.
Is stored.

At the front and rear inside the unit cover 2, support legs 8 having rollers 6 at the lower ends thereof are rotatably mounted on a horizontal shaft 9. At a substantially central position in the front-rear direction, a vertical bar 10 pointing in the vertical direction is fixed via fixing members 13 and 13 ′, and the vertical bar 10 has a through hole 11 penetrating in the vertical direction at the center. The weight member 12 is inserted movably in the up-down direction. The lower fixing member 1
Reference numeral 3 'restricts the downward movement of the weight member 12.

The weight member 12 has a link rod 15 serving as a leg holding means, which is pivotally connected at one end to a lower portion of the support leg 8 via a shaft 14, and the other end of the link rod 15 is pivotally connected via a shaft 16. A substantially inverted L-shaped engaging piece 20 is attached to the upper part of the weight member 12 so that the upper end can be engaged with the engaging claw 18 of the swinging member 19 whose upper end is rotatably mounted via a shaft 17. Have been.

The engagement between the locking claw 18 and the locking piece 20 is as follows.
The rotation is released by the counterclockwise rotation of the swing member 19. The weight member 12 has a predetermined weight, and when the engagement between the locking claw 18 and the locking piece 20 is released, the weight member 12 is automatically lowered by its own weight.

The front and rear surfaces of the unit cover 2 are provided with openings 21 in the longitudinal direction, respectively, and the front and rear support legs 8 are respectively connected to the front and rear surfaces 2a, 2b of the unit cover 2.
It can project more through the opening 21.

Next, the operation of the device for preventing the cabinet 1 from falling over according to the embodiment of the present invention will be described with reference to FIGS.
Description will be made based on FIG.

First, during normal use as shown in FIG. 2, the locking claw 18 of the rocking member 19 and the locking piece 20 are in the engaged state, and the weight member 12 is Supported in position. At this time, the front and rear support legs 8 are connected to the weight member 12 supported at the upper position by link rods 15, one ends of which are pivotally connected to the weight members 12.
It is held substantially vertically so as to be completely housed inside. At this time, the lower end of the roller 6 of the support leg 8 is slightly separated from the floor surface 22 so that the weight of the cabinet 1 is not added.

Next, when vibration occurs in the direction of arrow F in the figure on the floor surface 22 due to the occurrence of an earthquake or the like, the vibration is transmitted to the cabinet 1 and starts swinging. When the swing reaches a predetermined size, the swing member 19 is rotated as shown by a two-dot chain line in FIG. 2, and the engagement between the locking piece 20 and the locking claw 18 is released.

When the engagement between the locking piece 20 and the locking claw 18 is released, the weight member 12 is lowered. As shown in FIG. 3, as the weight member 12 is lowered, the link rods 15, 15 simultaneously rotate the respective support legs 8, 8 and project outward through the openings 21.

Eventually, the weight member 12 will be
The downward movement is restricted by the lower mounting member 13 'at a position where is substantially horizontal, and stops. At this time, both support legs 8, 8 project in a substantially C-shape and are non-rotatably supported by link rod 15.

Further, the vibration F is transmitted to the cabinet 1, and as shown in FIG. 4, when the cabinet 1 is tilted around the point P in the figure, the upper portion of the tilted cabinet 1 projects forward as described above. The cabinet 1 is supported by the supported support legs 8 to prevent the cabinet 1 from falling down.

Further, when the swinging operation of the cabinet 1 acts on the support legs 8, the vibration energy is absorbed by the rollers 6 rolling on the floor surface 22 in the vibration direction.
Falling is more effectively prevented. Instead of the roller 6, a sliding member (for example, a synthetic resin material) having a small sliding resistance may be attached to the lower end of the support leg 8 so as to be able to contact the floor surface 22.

As described above, since the support legs 8 are attached to the strong side plates forming a part of the cabinet 1,
Even if a large shaking occurs due to an earthquake or the like, it is possible to reliably support the storage fixtures. In addition, since it is normally stored on the side of the cabinet 1, it does not obstruct the user.

Further, since the overhanging support leg 8 is held by the tension of the link rod 15, it is not pushed back at least in the storage direction, nor is it overhanged beyond an appropriate position. The performance is improved.

Further, even if the cabinet 1 is tilted and a load is applied to the support legs 8 during the extension, the support legs 8 are smoothly moved in the extension direction by the rolling of the rollers 6.

When the weight member 12 moves downward, the support leg 8 is moved via the link rod 15 to the unit cover 2.
Since it is urged outward from the inside storage position and is always restricted from rotating in the storage direction, the urging means and the holding means for the support leg 8 are provided separately. Not only is there less erroneous operation than in the case where the device is installed, the structure is simplified, and miniaturization and cost reduction of the device are achieved.

Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention. Included in the invention.

For example, in the present embodiment, the support legs 8 are attached to the front and rear sides of both sides of the cabinet 1, but may be provided at only one of the front and rear sides of the cabinet 1 at least to prevent the cabinet 1 from overturning. .
