Description

[Detailed description of the invention] Industrial application field The present invention is a method for moving heavy objects having a structure that has a lower end space that is open toward the installation surface and that allows human hands to reach the space from above. This invention relates to a support structure for transportation to facilitate transportation. Examples of such heavy items include storage furniture, and for example, the portion surrounded by the architrave with its lower surface open and the bottom plate that can be opened and closed corresponds to the lower end space here. Here, storage furniture broadly includes chests of drawers, cupboards, bookshelves, cabinets, lockers, etc. In addition, the above-mentioned heavy objects include a vertical piano, an upright vending machine, a decorative installation, and the like.

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 lower end, but this makes the installation unstable and is not suitable when the installation surface is a tatami or rug. 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 vehicle for moving heavy objects, which has a hollow space at the lower end that is open toward the installation surface, and has a structure that allows human hands to reach the hollow space from above. a support structure comprising: an elongated movable support sized to be received within the lower end cavity and having horizontal plates at each end; a fixed support fixed in the lower end cavity so as to support each end; a moving member attached to the lower surface of the movable support; and support for both the movable support and the fixed support. A lever bar that engages with the body and can be rotated manually, and one of the supports is provided with a guide groove extending in the vertical direction at each location where the supports are adjacent to each other. The other support is provided with an engaging portion that engages with the guide groove, and the lever bar is connected to the fixed member so that the movable support can be moved up and down by being rotated in the vertical direction. A fulcrum forming part engaged with a support, a long operating part and a short operating part extending from the fulcrum forming part, the operating part:
The tip of the movable support is provided with an action point forming part that extends horizontally in the width direction and contacts the horizontal plate from above, and when the movable support is in the raised position based on the rotation of the lever bar, the movement A moving member is housed in a lower end cavity of the heavy object, and when the movable support is in a lowered position, the moving member protrudes from the lower end cavity, and the movable support is This is achieved by a support structure for moving a heavy object, which is adapted to be held in the lowered 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 body 1 including a frame 10 having a rectangular shape in plan view, horizontal plates 11 fixed to the lower edges of both ends of the frame, and a mounting fixed to the inner surface of the architrave D of the storage furniture. A fixed support 2 comprising a plate 20 and a support plate 21 extending vertically from the mounting plate to a position adjacent to both side ends of the frame frame 10.
, a moving member 3 attached to the lower surface of the horizontal plate 11, and a lever bar 4 that engages with both supports 1 and 2.
and a torsion coil spring 5 acting between both supports 1 and 2. The frame 10 of the movable support 1 is made slightly shorter than the depth dimension of the architrave D,
Vertical elongated holes 100 are formed at equal distances from the inner surface of the architrave D on each side surface of both ends. The fixed support body 2 has a long hole 1 in the frame frame between each pair of support plates 21 located on both sides of the frame frame 10.
00 and has an axis 22 extending through it. In this example, the moving member 3 is a swivel caster, but other materials may be adopted as appropriate, such as a sliding plate whose bottom surface is coated with fluororesin or a smooth metal surface. The lever bar 4 is a long and thin rod 40 with a short rod 41 fixed perpendicular to the tip thereof,
The lever bar 4 is movably supported by passing the shaft 2 into the vicinity of the short rod 40 so that the short rod 41 extends horizontally in the width direction of the movable support. When the lever bar 4 is in the tilted position shown in Fig. 1, the moving member 3 receives a reaction force based on the weight of the chest of drawers from the installation surface and sinks into the architrave D, and the lever bar 4 is moved manually to the weight of the chest of drawers. When the movable support 1 is lowered by the short rod 41 pushing down the horizontal plate 11, the moving member 3 is moved downward from the architrave. made to stand out. The amount of protrusion is determined depending on the weight of the chest of drawers, the condition of the installation surface, etc., but it is usually 10mm.
It is said to be about 20mm. The length of the elongated hole 100 in the frame, the distance between the shaft 22 and the tip of the short rod 41, and the height at which the fixed support 2 is attached to the architrave D are appropriately determined so as to obtain the above amount of protrusion. In this example, when the lever bar 4 reaches a position slightly beyond the consideration point (indicated by a dashed line in FIG. 3) based on the reaction force received by the moving member 3, it comes into contact with the short rod 41, and the lever bar 4 is rotated no further. A protrusion 110 for preventing movement is provided on the horizontal plate 11, thereby forming a detent mechanism. The torsion coil spring 5 is wound around a shaft 22 and has a mounting plate 20 having fixed supports at both ends.
The horizontal plate 11 of the movable support 1 is brought into contact with the movable support 1 and acts to push the movable support 1 downward.
This spring force is applied to the moving member 4 due to the weight of the chest of drawers.
is made to sink into the architrave D against the spring force.

Therefore, according to this moving support structure, the moving member 3 is normally stored in the architrave D with the lever bars 4 in the tilted position, and when necessary, each lever bar 4 is brought to the upright position and moved. By making the storage member 3 protrude from the architrave D, the chest can be easily moved. The force required to raise the lever bar 4 is due to the lever action and the spring 5.
With the addition of this effect, it has been considerably reduced. The movable support 1 is guided by the elongated hole 100 and the shaft 22 and lowered, but at this time it is pressed by the short rod 41 extending in the horizontal direction, so rotation (wobble) around the horizontal axis is prevented and it is stabilized. You can get the desired behavior.

In the above example, the shaft 22 served as both the engagement with the elongated hole 100 and the fulcrum of the lever bar 4, but these roles can also be assigned to separate shafts or convex parts. In this case, contrary to the previous example, it is also possible to provide the long hole in the fixed support 2 and the shaft (projection) in the movable support 1. The torsion coil spring 5 can also be replaced with a compression coil spring or an air spring as appropriate. In addition to the above-mentioned detent mechanism, a mechanism using a locking member such as a pin or a hook for locking and fixing the pry bar 4 to the movable support 1 in the pry bar tilted position may be used as appropriate.

Figure 4 shows that when the pry bar 4' is in the upright position,
An example in which the moving member 3 is housed in the architrave D is shown. By rotating the lever bar 4' in the direction of arrow A from the position shown, the short rod 41'
pushes down the horizontal plate 11, causing the moving member 3 to protrude below the architrave D. In this example, the lever bar 4' has a bent shape at the support portion of the shaft 22, as shown. In the drawings, like members are given the same reference numerals.

The present invention can be applied to other storage furniture and other heavy objects having a hollow space at the lower end in the same manner as the above-mentioned example of the wardrobe.

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 vertical 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.
