Description

[Detailed description of the invention] The present invention relates to a retractable wagon, that is, a wagon that has casters attached to its lower part so that it can roll and is stored in a storage space formed on a laboratory table or other work table when not in use. Its purpose is to
This is intended to prevent accidental rolling or overturning and escaping from the storage space in the stored state, especially to prevent overturning in the event of an earthquake.

Conventionally, structures for preventing wagons from rolling or overturning have been constructed by using casters with stoppers or by removably connecting chains or latches placed at appropriate locations for furniture storage to the top or sides of the wagon. However, when using casters with stoppers, it is possible to prevent rolling, but it is not possible to prevent falling or slipping in the event of an earthquake.On the other hand, when using a connecting structure with chains or latches, it is possible to prevent the wagon and The problem remains that not only is the structure for linking the storage spaces complicated, but also the operation of connecting and disconnecting the connecting parts is troublesome.

The wagon device of the present invention has a rotating mechanism that allows the engaging member provided at the bottom of the wagon to automatically engage with the engaging portion formed in advance in the storage space simply by pushing the wagon device into the storage space and storing it. The gist of the invention is that it has a mechanism to prevent movement and falling.

As explained below with reference to the attached drawings, the wagon device A of the present invention has a box-like main body 1 with a shelf inside or an extractor installed, and a bottom plate 3 on the lower side of the bottom plate, with the front part serving as an operating part, and the rear end serving as an operating part. The latch part 1 in the storage space B'
An engaging member 8 is provided as an engaging member 8 for engaging with the member 5. For example, in the case of FIGS. 2 and 4, the bottom plate 3 is fixed between the side plates 2 and 2 of the main body 1 at a constant distance from the lower edges of both sides, and casters 5 are attached to the lower surface of the bottom plate 3 via reinforcing members 4. ... is provided to make the wagon rollable, and a support plate 6 of a pair or integral shape of an angle or other shape is provided downwardly protruding from the bottom surface of the bottom plate 3, and a support shaft is horizontally fixed to the support plate 6. The hooking member 8 is attached to the hook 7 in such a manner that it is rotatable and the weight is heavier at the tip (rear end) side.

The hooking member 8 is made of a rod or a plate whose tip, i.e., the rear edge, is an inclined edge 9 facing downward toward the front, and a hooking recess 10 is formed in the lower edge adjacent to the inclined edge. For example, as shown in FIG. 4, by bending the plate, a hooking member 8 consisting of a flat plate portion 11 and both side plates 12 is formed, and the above-mentioned inclined edges 9 and hooking recesses 10 are formed on both side plates 12. The front part of 11 is used as a foot pedal 13. In addition, to hold the hook member 8 when the wagon is pulled out and the hook member 8 is not in use, and in particular to prevent the front (backward) part from the pivot point of the support shaft 7 from rotating downward and falling to the floor. It shall be held by a stopper 14 provided at an appropriate position on the bottom plate 3 of the main body. An example of this stopper 14 is a downwardly bent front lower stile on the front edge of the bottom plate 3, which prevents the portion of the engaging member 8 in front of the pivot point of the support shaft 7 from upwardly rotating beyond a certain level. There is.

On the other hand, the hooking part 15 in the storage space B' that engages with the hooking member 8 can be fitted into the hooking recess 10 of the hooking member 8, and the height of the upper end 15' can be adjusted to the height of the hooking member 8 when not in use. It is formed in the storage space B' so as to be located within the vertical dimension of the inclined edge 9. For example, as shown in FIG. A vertical piece may be formed by fixing the vertical piece, and the engaging member 8 may be engaged with this vertical piece, or a horizontal shaft may be provided in place of the vertical piece.

According to the wagon device of the present invention as described above,
The engagement recess 10 formed at the tip (rear end) of the engagement member 8 provided at the lower part of the wagon body 1 is always urged downward, and the inclined edge 9 formed at the tip edge is connected to the storage space B. Since the wagon device can be brought into contact with the latching portion 15 inside the latching portion 15, the slanted edge 9 of the engaging member 8 will come into contact with the latching portion 15 by simply pushing the wagon device into the storage space of the workbench B and storing it. At the same time, it is pushed up around the support shaft 7 by sliding, and the engagement recess 10 fits into the engagement part 15 to be in an engaged state, and other operations can be performed by simply pushing and storing the wagon. Engagement can be performed to prevent rolling and overturning without the need for it. Also, when pulling out the wagon device, the operating section on the front side of the engaging member 8,
For example, by depressing the foot pedal 13, it is possible to easily disengage the engagement recess 10 and the latching portion 15.

In addition, when the hooking member 8 is configured as an integral body consisting of the side plates 12 and the flat plate part 11, the side plates 12,1
By forming an inclined edge 9 and a hooking recess 10 at the tip of the wagon device 2, and fitting these two hooking recesses 10, 10 into the hooking portion 15, the engagement is made more reliable. This can prevent accidental rolling and overturning of A, and also prevent the engaging member 8 from twisting relative to the support shaft 7.
