The object of the present invention is to solve these conventional problems and provide storage furniture that can be stably installed on any installation surface and that can be easily moved when necessary.

Means for Solving the Problems The object of the present invention is to provide an arm device and a lever device in the lower end spaces on both left and right sides of the storage furniture, and each arm device is arranged at the front and rear portions inside the lower end of the storage furniture. two arms whose proximal ends are pivotally supported by the two arms so as to be rotatable in the vertical direction, and whose distal ends extend in opposite directions, and a moving member attached to the lower surface of each arm on the proximal end side from the distal end thereof. The lever device includes a lever that is pivotally supported inside the lower end of the storage furniture substantially above the tip of one of the arms and is rotatable in a direction along the arm, and a tip of the other arm. a rotor that is pivotally supported on the inner side of the lower end of the storage furniture at a portion above the rotor so as to be able to rotate in a direction along the arm and in contact with the other arm; and a lever configured to transmit the rotation of the lever. and a connecting member that connects the rotor, and the lever includes an elongated operating section that extends from the pivot support and is rotatable from a substantially horizontal tilted position to the upright side and vice versa, and the operating section. a short operating section that rotates while abutting the one arm as the operating section rotates, and the lever is configured to rotate the operating section when the operating section is rotated from the tilted position to the upright side. The actuating section pushes down the one arm, and the rotor pushes down the other arm based on the transmission by the connecting member, and the pressed down state is maintained by an appropriate detent mechanism, while the lever , when the operating section is returned to the tilted position with the release of the detent mechanism, the arm is released from being pressed down by the actuating section and the rotor, and the moving member is configured to prevent rotation of the lever. This is achieved by a storage furniture characterized in that the arm is caused to protrude from the lower surface of the storage furniture by pressing down, and can be retracted into a space at the lower end of the storage furniture by releasing the depression by returning the lever. be done.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a vertical side view of the wardrobe, and FIG. 2 is a cross-sectional view thereof. This wardrobe is located on both the left and right sides of architrave 1 (only one is shown in the figure).
is equipped with an arm device 2 and a lever device 3, both of which are mounted inside the architrave 1 via a frame 4. The frame 4 is made up of a pair of metal plates having a U-shaped cross section extending in the longitudinal direction of the wardrobe, arranged in parallel with each other at a distance, and both end surfaces fixed to the inner wall of the architrave 1. Of course, it is also possible to omit the frame 4 and provide a suitable crosspiece to attach both devices 2 and 3 directly to the architrave 1. Each arm device 2 has a first arm device 2 whose base end is supported by shafts 200 and 210 at the front and rear ends of the frame and is rotatable in the vertical direction.
It includes an arm 20, a second arm 21, and moving members 22, 23 attached to these arms. The first arm 20 and the second arm 21 are
As shown in FIG. 1, there are support parts 201 and 211 that are approximately horizontal when the moving members 22 and 23 protrude from the lower surface of the architrave, and bent parts that are bent downward from the support parts toward the tip side. Extending pressure receiving part 202,2

is attached and both ends are attached to the inner wall of architrave 1 and arm 2.
0 and 21 to lift the arms 20 and 21. The moving members 22 and 23 are attached to the lower surfaces of the arm supports 201 and 211, respectively. The moving members 22 and 23 are made of swivel casters in this embodiment, but other materials may be used as appropriate, such as sliding plates whose bottom surfaces are coated with fluororesin or have a smooth metal surface. The lever device 3 includes a lever 30 supported by a shaft 300 substantially above the tip of the first arm 20, a rotor 31 supported by a shaft 310 substantially above the tip of the second arm 21, and the lever 30 and the rotor 31. and a connecting member 32 that connects the.
The lever 30 is a pair of plates 301, 301 connected by rods 302, 303, and a shaft 300 is provided between each plate 301 and the frame. The lever 3 has a long operation section 304 from the shaft support of the shaft 300 to the rod 302, and a short operation section 305 from the shaft support to the rod 303. They form an obtuse angle with each other.
The lever 30 is arranged so that the operating part 305 extends upward when the operating part 304 is tilted toward the second lever 21 so that it is approximately horizontal (see Fig. 3), and in order to maintain this position. A stopper pin 306 is attached to the frame 4. The lever 30 is configured so that the operating section 304 can be rotated from this tilted position to the side where it stands up, and as the operating section 305 rotates, the rod 303 causes the operating section 305 to push down the pressure receiving section 202 of the first arm. is being used. As is clear from FIG. 3, the shape of the pressure receiving part 202 is determined so that the distance from the lever shaft 300 becomes shorter toward the tip when the moving member 22 is stored, and based on this, the rotation of the actuating part 305 is determined. Accordingly, the first arm 20 is pushed down. In this embodiment, the rod 303 is further locked when the actuating section 305 reaches a position slightly past the point (dotted chain line A in FIG. 1) corresponding to the reaction force from the pressure receiving section 202. A locking portion 204 is provided by bending the tip of the first arm 20, and this structure forms a detent mechanism. The rotor 31 includes a pair of plates 311, 3
11 are connected by a rod 312, and the shaft 3
10 is provided between each plate 311 and the frame 4. The connecting member 32 includes rods 320 and 321 provided on the lever 30 and the rotor 31.
The rotor 31 is provided so as to extend between the levers 30 and 31 to transmit the rotation of the lever 30 to the rotor 31. When the rotor 31 is rotated in this way, the rod 3
12 is brought into contact with the pressure receiving part 212 of the second arm, thereby pushing down the second arm 21. For this purpose, the shape of the second arm 21 and the shape of the detent mechanism formed by the locking portion 214 at the point of passage (FIG. 1B) are similar to those described for the first arm 20. In this way, both the first arm 20 and the second arm 21 are activated by rotating the lever 30 from the tilted position (FIG. 3) to the upright side (FIG. 1), so that the rod 204 of the actuating part and the rotor, respectively, are rotated. It is pushed down by the rod 214 and held in the depressed position by the detent mechanism described above. When the lever 30 is reversely rotated from the upright side, the detent is released by passing the above-mentioned consideration point again, and when the lever 30 is returned to its original tilted position, the arm 2
The push to 0 and 21 is released. Moving member 2
2 and 23 protrude from the lower surface of the architrave 1 against the weight of the chest when the arm is pressed down, and retract into the architrave 1 when the arm is released. In addition, in this embodiment, the torsion spring 203,
213 urges the arms 20 and 21 to fit into the architrave, so that even when the chest of drawers is lifted, the moving members 22 and 23 are retained within the architrave without descending due to their own weight. It's getting old. Further, a portion of the bottom plate of the chest of drawers is removable so that the lever 30 can be rotated manually.

4 and 5 each show the main parts of an embodiment different from the above, and similar parts or parts in the figures are given the same numbers.

In the example shown in FIG. 4, each pressure receiving part 202, 212 of the first arm 20 and second arm 21 is formed in an arc shape, and when the moving member is stored, the shafts 300, 310 extend toward the tip of the pressure receiving part. The distance is shortened. When the lever 30 is rotated to the upright side, the rod 303 of the actuating part and the rod 312 of the rotor press and slide on the concave curved surface formed as described above, and the time required from the beginning to the end of the lever rotation is Force becomes more even. Fourth
In the illustrated example, the connecting member 32 transmits the rotation to the rotor 31 while receiving a compressive force when the lever 30 rotates from the illustrated position.

In the example shown in FIG. 5, the operating portion 30 of the lever 30
5 and the rotor 31 are each provided with arcuate plates 303 and 312 that constitute cam surfaces instead of rods. As the lever and rotor rotate from the illustrated position, the arcuate plates 303 and 312 touch the pressure receiving parts 202 and 212 and the shafts 300 and 3.
10, so that the lever 30 can be rotated with a substantially uniform force. As in the first example, the detent mechanism at the arm push-down position presses the stopper pin 30 at a position slightly beyond the point corresponding to the reaction force from the pressure receiving part.
The lever 30 and the rotor 31 are configured to abut against the levers 7 and 308, respectively. In addition, as the detent mechanism, a mechanism using a hook or pin for locking the lever device or arm device to the frame can be adopted as appropriate, and the same applies to other embodiments.

The present invention can be applied to other storage furniture in the same way as the wardrobe example.

Effects of the Invention As is clear from the above explanation, according to the present invention, storage furniture that has the following effects can be provided. That is, since a moving member is provided in the lower end of the storage furniture, the moving member can be placed in the space and protruded downward from the lower surface of the furniture. It can be housed and stably installed on any installation surface, and when moving, by protruding the moving member downward, the stored furniture can be easily moved based on the moving member.

The operation to bring the moving member to both positions is extremely easy as it only involves rotating the lever in the front and rear directions, and the lever action of both the lever and the arm for supporting the moving member reduces the amount of manpower required to rotate the lever. The force required is greatly reduced, making operation easier.
