効果を有している。 Since the present invention has the above-described structure, by rotating the front handle 14, the handle shaft 1
3. The elevating gear 10 rotates via the worm gear device 12, the connecting shaft 11, and the gear shaft 9, and the leg member 5, which is engaged with the elevating gear 10 through the rack 8, moves in the vertical direction to raise and lower the top plate 3. be able to. At this time, since the leg member 5 is held by the sliding holder 7 as described above, it can be moved up and down extremely smoothly. As mentioned above, the top plate elevating device of the present invention has a support frame 4 having a substantially U-shaped cross section and having support plate portions 4a, 4a on both sides erected on the base 1, and the above-mentioned support plates on both sides of the support frame 4. Side plate parts 5b, 5 facing parts 4a, 4a, respectively
Since the leg member 5 for the top plate having an approximately rectangular cylindrical shape or a substantially U-shaped cross section is fitted so as to be movable up and down, the structure of the leg is extremely simple, and as described above, the front corner of this leg member 5 Plate portions 6 that are substantially perpendicular to each other on the inside
A sliding holder 7 is provided between the plate part 6a facing the support plate part 4a of the support frame 4, and the engagement plate 6 having a substantially L-shaped cross section having the shapes a and 6b fixed vertically.
The other plate part 6b perpendicular to this plate part 6a is interposed to smooth the vertical movement of the leg member 5.
Since a rack 8 is formed on the rack 8 and a lifting gear 10 pivotally supported on the support plate portion 4a is meshed with the rack 8, the holding of the leg member 5 and the lifting device thereof can be made extremely compact by the engaging plate 6. The structure is simple, the number of parts is small, and together with the simplified leg structure described above, it has practical effects such as extremely easy manufacturing.
