BACKGROUND ART AND PROBLEMS THEREOF For example, storage furniture is often large and heavy, and once installed, it is often difficult to move it. Some storage furniture is equipped with casters at the bottom end, but this makes the installation unstable, and if the installation surface is a tatami mat or rug, heavy loads will be placed on the casters, making it difficult to install for a long period of time. This is not suitable because it deforms the installation surface. In addition, ease of movement is required for other heavy objects, but in many cases it is not desirable to use moving parts such as casters all the time from the standpoint of stability and aesthetics during installation. .

In order to meet such demands, the present invention has been developed to provide a heavy object that can be stably installed by the lower end surface of the heavy object at all times, and when necessary, a moving member can be made to protrude from the lower surface of the heavy object to facilitate movement. The purpose is to provide a support structure for the movement of.

Means for Solving the Problems The object of the present invention is to provide a heavy object that has a lower end space that is open toward the installation surface and has a structure that allows human hands to reach the space from above. The moving support structure is provided at each horizontally separated position of an object, and includes a fixed support fixed within a space at the lower end of the heavy object, and a movable support structure movable with respect to the fixed support and substantially perpendicular to the horizontally separated direction. a movable support guided by the fixed support along a vertical plane, a moving member attached to the lower surface of the movable support, and a movable member that engages with both the fixed support and the movable support. and a lever rod that can be rotated in a substantially horizontal plane by a hand reached from above the void,
One of the two supports is arranged parallel to each other along the vertical plane so that both ends of the support that are spaced apart from each other in the direction along the vertical plane are at the same height from the heavy object installation surface. A guide groove provided at an angle is provided, the other support body is provided with an engaging portion that engages with the guide groove, and the lever bar is engaged with both supports and rotated. A lever bar locking portion is provided so that the movable support body is guided by the guide groove and moved parallel to the fixed support body, and the vertical length of the guide groove is equal to the length of the moving member. has a length sufficient to allow the heavy object to assume a raised position in the lower end cavity and a lowered position protruding from the lower end cavity based on the parallel movement, and the movable support This is achieved by a support structure for moving a heavy object, which is characterized in that it can be held in position by a detent mechanism.

Embodiments Hereinafter, an example in which the present invention is applied to storage furniture will be described with reference to the accompanying drawings.

FIG. 1 is a vertical sectional side view of the lower part of a wardrobe equipped with a moving support structure according to the present invention, and FIG. 2 is a cross sectional view thereof. The moving support structure is usually provided on both the left and right sides of the storage furniture, but the figure shows only one of them. This moving support structure includes a movable support 1 having a rectangular shape in plan view, a fixed support 2 fixed to the inner surface of the architrave D of the storage furniture, and a moving member 3 attached to the lower surface of the movable support 1. , a lever bar 4 that engages with both supports 1 and 2, and a tension coil spring 5 that acts between both supports 1 and 2.

The guide groove 22 has a width that allows the engagement pin 12 of the support body 1 to pass through it almost tightly, and engages with the pin, and in this embodiment, it is a detent that extends a short distance while rising slightly from the lower end. The portion 220 is formed continuously. The length of the guide groove 22 in the vertical direction is the length of the engagement pin 1
2 is at the upper end, the moving member 3, which will be described later, assumes a position housed within the architrave D, and when the engagement pin 12 is at the lower end, the moving member 3 protrudes downward from the architrave D. It is said to be of similar length. The moving member 3 is
In this embodiment, the casters are swivel casters and are fixed to the lower surface of both ends of the movable support 1. Of course, the moving member may be constructed as appropriate, such as by using a sliding plate whose bottom surface is coated with a fluororesin or a smooth metal surface. The lever bar 4 has a pair of upper and lower plates 40 extending horizontally, a fulcrum forming rod 41 at one end, an action point forming rod 42 provided at the tip at a short distance from the rod, and a handle at the other end. 43, and the fixed support 2
The upper and lower support plates 23 are sandwiched between the upper and lower support plates 23 at the one end. The fulcrum forming rod 41 is supported by the shaft hole 231 of the support plate 23 and extends through the long insertion hole 101 of the movable support 1, and the action point forming rod 42 is supported by the long hole 230 of the support plate 23 and the movable support. It extends through the locking elongated hole 100 of the body 1 . A pair of tension coil springs are provided, and both ends are supported by pins 210 and 110 provided on the side wall 21 of the fixed support 2 and the side wall 11 of the movable support 1, respectively, and the movable support 1 is moved to the right in the figure.

1 and 230 are formed so that the support members 1 and 2 do not come into contact with the fulcrum forming rod 41 and the action point forming rod, respectively, during the downward rightward movement.
The spring force of the tension coil spring 5 is such that the movable support body 1 and the moving member 3 are retracted into the architrave D against the spring force due to the weight of the chest of drawers.

Therefore, according to this moving support structure, the moving member 3 is normally placed on the architrave D with the lever bar 4 in the rear position.
When necessary, the lever bar 4 is brought to the front position to cause the moving member 3 to protrude from the architrave D, making it possible to easily move the chest of drawers. Pry bar 4
The force required for rotation is considerably reduced by the addition of the action of the spring 5 on top of the leverage action. At this time, since the guide grooves 22 in each fixed support 2 are inclined parallel to each other, and the engagement pin 12 is engaged with the guide groove 22, it can be moved by pushing one part with the lever bar 4. The support body 1 moves in parallel while maintaining a horizontal attitude. In the final state in which the moving member 3 protrudes below the architrave D, the engaging pin 12
has reached the detent portion 220 of the guide groove 22, so the slight upward inclination of the detent portion 220 allows the movable support 1 to stably move to the moving member protruding position against the reaction force from the installation surface. Retained. The detent portion 220 thus serves as a detent mechanism for the movable support 1.

In the above example, the engagement pin 12 is provided on the movable support 1 and the guide groove 22 is provided on the fixed support 2. However, the engagement pin is provided on the fixed support and the guide groove is provided on the movable support. It is also possible to provide one. In this case, it goes without saying that the height of the side wall of the movable support (the height if the movable support is formed solid) is set to be high enough to correspond to the guide groove.

As the detent mechanism, in addition to the detent part 220 in the guide groove 22 described above, through holes are provided in the movable support 1 and the fixed support 2 that align when the movable support 1 reaches the lower position. Any suitable means such as passing a pin through a hole may be employed.

FIGS. 5 and 6 show other embodiments.
In this example, a notch 24 is formed in the center of the side wall 21 of the fixed support 2, and the upper and lower support plates 23 protrude toward one side wall 21, in which a shaft hole 231 is provided. The movable support 1 does not have the elongated insertion hole of the previous example, and instead of the elongated locking hole, a locking notch 100' is provided on one side edge of the center portion. The lever bar 4 has a pair of upper and lower plates 40 connected by an action point forming rod 42 and a handle 43 at an interval that allows the plates to be inserted into the above-mentioned notch 24.
A fulcrum forming rod 41 extends through the shaft hole 231
It is rotatably attached to the support plate 23 by. The point-of-action rod 42 is engaged in a recess 100' of the movable support 1. The lengths of the action point forming rod 42 and the handle 43 are set to at least exceed the vertical movement dimension necessary for storing and protruding the moving member 3, and the height of the notch 24 of the fixed support 2 is determined accordingly. It will be done. Other configurations are similar to the previous embodiment.

Therefore, in this embodiment as well, the moving member 3 is normally stored in the architrave D with the lever bar 4 in the rear position, and when necessary, the lever bar 4 is brought to the front position to move the moving member 3 into the architrave. It can be made to protrude from D, making it easier to move the chest of drawers.

The present invention can be applied to other storage furniture and other heavy items having a hollow space at the lower end in the same way as the wardrobe example.

In the moving support structure according to the present invention, the support structure part can be assembled separately from the heavy object and attached to the heavy object, or a part of the lower end of the heavy object can be used as a fixed support. It can also be integrated into the heavy object.

Effects of the Invention As is clear from the above description, according to the present invention, it is possible to provide a support structure for moving heavy objects that has the following effects. In other words, a moving member is provided in a space at the lower end of a heavy object so that it can be stored in the space and in a position protruding downward from the space. The heavy object can be stored and stably installed on any installation surface, and when moving, the moving member can be projected downward to easily move the heavy object.

The operation for protruding the moving member is extremely easy as it only involves rotating the lever bar in the horizontal direction and holding the protruding position using the detent mechanism, and the action of the lever bar greatly reduces the required manual force. has been done.
