[Embodiment of the invention]

 FIG. 1 is a front view of an apparatus according to a fourth embodiment, FIG. 2 is a left side view of FIG. 1, and FIG. 3 is a plan view. In FIG. 1, reference numerals 1 and 1 denote support columns erected near both end edges of the vertical side of a work table 5, and reference numerals 2 and 2 denote bridge plates connecting upper and lower ends. Reference numerals 3 and 3 denote guide bases extending in the horizontal direction perpendicular to the both end portions of the lower bridge plate 2. In this embodiment, each column 1 has a pair of plate members 1a and 1b opposed to each other, and a guide mechanism for guiding a vertical movement of a piston rod of a fluid cylinder described later is provided on the opposed surface.

[0006] Reference numerals 4 and 4 denote X-arm pantograph mechanisms. One of the lower ends of the X-legs is fixed to one end of the guide bases 3 and 3, and the other is one. A guide rail 3a formed on the other side of the guide base 3 is slidably moved by using a roller m.

Reference numeral 5 denotes a work board having a fixed width and length. One of the upper ends of the X-legs of the pantograph mechanisms 4 and 4 is fixed to one of the back sides of the work board, and the other is provided. One of them is slidably moved via a roller m in a guide rail 5a provided on the back side of the work table plate 5 on the extension thereof.

[0008] Numerals 6 and 6 denote fluid cylinders which are attached to the columns 1 and 1 in an upright state. Specifically, the fluid cylinders flow onto the bridge plate 2 between the opposed plate members 1a and 1b in each column. The body cylinder 6 is mounted in an upright state, and when the fluid cylinder 6 is actuated, a flange member P provided on the head of the piston rod 6a is guided by the internal guide grooves of the plate members 1a and 1b and moves up and down in the vertical direction. Is made. Thus, a sprocket or pulley 7 is supported on the collar member P by the use of a bearing member 8 so as to be able to rotate.

Reference numerals 9 and 9 denote chains or wires for holding the work table plate 5 in a lifting manner in the height direction of the columns 1 and 1, one end of which is attached to one upper edge of the work table plate 5. The other end of the sprocket or pulley 7 has a chain or wire on the back side of the columns 1 and 1 with respect to a locking plate 10 protruding near the lowered position of the piston rod 6a of the fluid cylinder. 9 is engaged. The length of the chain or the wire 9 is such that the work table plate 5 is at the lowest position on the ground at the limit point of the lowering of the piston rod 6a, and the pantograph mechanism can be safely folded.

Next, when the fluid cylinder 6 is not operated, as described above, the piston rod 6a is safely folded at the lower limit position (see the dashed line in FIGS. 1 and 2) of the pantograph mechanism as described above. In this state, the work board 5 is at the lowest position which is almost the same as the ground. Thus, when the fluid cylinder 6 is actuated, the piston rod 6a rises, and at this time, the sprocket or pulley 7 mounted on the head rotates the chain or wire 9 upward while rotating. Thereby, the work base plate 5 rises along the columns 1,1. The operation of the fluid cylinder 6 in the above is performed by an operator using an operation panel fixed to a support or appropriately held by a hand.

In the above-described embodiment, the support columns are arranged on both ends of the vertical sides of the work table plate. However, as shown in FIG. 4, the support plates are sandwiched between the horizontal sides (width direction) of the work table plate. It may be provided next to it. At this time, the arrangement of the guide base is the same as the previous example, and the arrangement position of the columns 1, 1 is such that one of the upper ends of the X-shaped arms of the pantograph mechanism is attached to the back side of the work table plate 5. It is arranged on the side of a considerable part. In addition, from the viewpoint of diversity in use, one of the above-mentioned columns can be freely provided at the center of the vertical side as shown in FIG. 5 or only one at the horizontal side as shown in FIG. it can. 4 and 6, two or more units can be arranged in series, and FIG. 5 can be arranged in parallel. In the above modification, the guide bases are generally designed in a plurality of arrangements (usually two rows).

[Effect of the invention]

 As described above, the present invention holds the work table plate in a suspended state with a chain or a wire, so that the work table is lifted and lowered, so that the work table is quickly lowered to the lowest lower limit position near the ground surface, The loading and unloading of workers and heavy objects can be performed easily, accurately and efficiently, and workability is improved. It should be noted that the arrangement of the pillars can be changed as appropriate to enable a variety of uses, which is very effective in achieving a work factory.
