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. Storage furniture here broadly includes chests, 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 bottom end, but this makes the installation unstable, and if the installation surface is tatami or carpet, the casters are subject to heavy loads, making it difficult to install them for long periods of time. This is not suitable as 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 supported on one end side of the fixed support in the direction along the vertical plane. a lever bar rotatably coupled to both supports by a pivot shaft and an engagement shaft supported by the movable support near the pivot shaft, the lever bar being reachable from above the cavity; These shafts are arranged so that the engagement shaft takes a position substantially horizontal and a position substantially perpendicular to the rotation shaft in response to rotation along the vertical plane by a human hand. One of the supports is provided with a guide groove extending along the vertical plane in a portion corresponding to the other end of the fixed support, and the other support is provided with a guide groove extending along the vertical plane. An engaging portion that engages with the groove is provided, and the guide groove extends at the same height as both end positions of the movement range of the engagement shaft when the lever bar rotates, and is approximately parallel to a straight line connecting the two ends. The movement range of the engagement shaft is such that the movement of the engagement shaft causes the movable support body to move up and down along with the movement of the engagement portion, and the moving member moves toward the heavy object. a weight having the necessary vertical distance to be raised and retracted from the lower end cavity, the movable support being adapted to be able to be held in the lowered position by a detent mechanism; This is achieved by a support structure for the movement of objects.

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 movable support 1 extends in the depth direction of the architrave D and has a length such that it can move within the architrave D as described below. It has a side wall 11 that stands up. The fixed support body 2 is formed into a rectangular shape in plan view, including two end walls 20 and side walls 21 on both sides thereof,
It is provided in the architrave D so as to surround the movable support 1. The distance between the side walls 21 of the fixed support 2 approximately corresponds to the width of the movable support 1, so that the movable support 1 is guided along a vertical plane along the longitudinal direction of the support. It's summery. A rotating shaft 22 extending in the width direction of the fixed support 2 is provided at one end of the fixed support 2, and a lever bar 4 is supported on the rotating shaft 22. As shown in the figure, the lever bar 4 is made by connecting two elongated plates with an engaging shaft 40 at one end and a gripping rod 41 at the other end. are arranged substantially in a straight line and are located near the engagement shaft 40. This allows the lever bar 4 to rotate in the longitudinal direction of the chest of drawers between a substantially horizontal tilted position and a substantially vertical upright position. A guide groove 23 is provided in the side wall 21 of the other end of the fixed support 2 . The guide groove 23 is the engagement shaft 4 when the lever bar 4 rotates.
It is provided so as to extend approximately at the same height as both end positions of the movement range of 0 and to be inclined approximately parallel to the straight line connecting the both ends. However, in this embodiment, the guide groove 23 includes a detent portion 230 at its lower end that extends slightly upwardly over a short distance. Rotating support 1
As shown in the figure, an engaging pin 12 is provided protrudingly from the side wall 11 to engage the guide groove 23 in a substantially tight manner. As a result, when the lever bar 4 rotates, the movable support 1 moves up and down based on the movement of the engagement shaft 40 and the movement of the engagement pin 12 within the guide groove 23. The separation distance between the rotation shaft 22 and the engagement shaft 40 is a distance necessary for the moving member 3 to move out and out of the architrave D due to the vertical movement of the movable support. Moving member 3
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. A pair of tension coil springs are provided, and are connected to the side wall 21 of the fixed support 2 and the movable support 1.
Pins 210 and 11 provided on the side wall 11 of the
0 at both ends, and acts to move the movable support 1 to the right in the figure. 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 in the architrave D with the lever bar 4 in the tilted position.
When necessary, the lever bar 4 is brought to the upright position to cause the moving member 3 to protrude from the architrave D, making it easy to move the chest of drawers. Pry bar 4
The force required to stand up is considerably reduced by the addition of the action of the spring 5 on top of the lever action. In the final state in which the moving member 3 protrudes below the architrave D, the engagement pin 12 engages with the detent portion 2 of the guide groove 23.
30, the movable support 1 is stably held at the moving member protruding position by the slight upward inclination of the detent portion 230 against the reaction force from the installation surface. The detent portion 230 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 23 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.

The positional relationship between the rotating shaft and the engaging shaft in the lever bar can be determined in various ways such that the engaging shaft is aligned approximately horizontally or substantially perpendicularly to the rotating shaft. For example, the rotation shaft 2 in the above-mentioned embodiment
2 and the engagement shaft 40 can be reversed; in this case, when the lever bar is rotated from the upright position to the tilted position, the moving member will protrude from within the architrave. . Further, the engagement shaft may be arranged so as to be separated from each other substantially perpendicularly to the longitudinal direction connecting the rotation shaft and the manual operation section (gripping rod).

As the detent mechanism, in addition to the detent part 230 in the guide groove 23 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 adopted.

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 housed 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.
