Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting table.

[0002]

2. Description of the Related Art In a conventional lifting type table, a vertical pedestal is fixed to the center of the base of a supporting leg, and the upper end of a lifting device incorporated in the pedestal is attached to the central part of the lower surface of a quadrilateral top plate. In some cases, the operating lever of the lifting device is provided on the front part of the lower surface of the top plate.

[0003] This is stable because the weight is well balanced, but the pedestal extending downward from the center of the lower surface of the top plate often hits the user's foot, which makes it difficult to use, and the casters are difficult to use. If you don't have it, it will be difficult to move. Further, in this structure, especially when the top plate is small, the knee tip may hit the pedestal, so there is a limit to downsizing.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned problems of the prior art and to provide a lifting table which is easy to use and can be downsized.

[0005]

In the lifting type table of the present invention, the lower end of a pedestal whose upper part inclines slightly forward is fixed to the base of the support leg that opens in a V shape from the base forward. and the upper end of the built-in lifting device to the pedestal, the plane
The shape is almost triangular, with its long side on the front side and
The long side portion is fixed to a position near the rear edge of the lower surface of the top plate that is recessed rearward, and the operating body of the lifting device is provided at the center of the front portion of the base of the support leg. It is characterized by that.

The lifting device may be a gas spring.

The operating body is preferably a foot pedal.

Casters are preferably provided on the lower surface of the pedestal and the front end of the supporting leg, respectively.

[0009]

1 is a perspective view of an embodiment of the present invention, FIG. 2 is a bottom view thereof, FIG. 3 is a rear view thereof, and FIG. 4 is a sectional view taken along line IV-IV of FIG. It is a figure. In the figure, (10) is a support leg, (11) is its base, (12) is the base (11).
From left to right in a V-shaped branch, (13)
Is a caster attached to the lower surface of the base (11) and the lower surface of the front end of the branch leg (12) of the support leg.

Reference numeral (20) is a pillar that supports the top plate (30) on the support leg (10) so as to be able to move up and down. (21) is the pedestal cover, (22)
Is a lifting device built in the pedestal (20), such as a gas spring device, and (23) is a support leg at the lower end of the pedestal (20).
The connected body is fixed to the base of (10).

Reference numeral (24) is an operating rod of the lifting device (22), which is a pedal provided so as to project toward the center of the front surface of the base portion (11) of the supporting leg (10).
It can be operated up and down by (25). (26)
Is the fulcrum of the pedal (25).

Reference numeral (27) is a support metal fitting that fixes the upper end of the lifting device (22) to the top plate (30) via the top plate support plate (31). Near the trailing edge (33) of the (30).

In order to make the top plate (30) easier to use, compared to a normal quadrilateral top plate, the top plate (30) has a substantially forward triangular shape like the left and right corners that are hard to reach with both hands. Has been formed.

If necessary, the front edge (32) of the top plate (30) may be arcuately recessed rearward to provide a top plate that is ergonomically easy to use. Besides, top plate
(30) has no corner portion at all, and the edge portion is finished so as to have an outward semicircular shape in a longitudinal section.

To raise the top plate (30), the pedal (25) is depressed while supporting the top plate (30) with both hands. Then, the lifting device (22) expands, and the support metal fitting (27) at the upper end of the lifting device (22) extends.
(30) is pushed up, so when the desired height is reached, pedal
Take your foot off (25).

To lower the top plate (30), hold down the pedal (25) and lower the top plate (30) with both hands. When the top plate (30) is lowered to the desired height, take your foot off the pedal (25). Good.

[0017]

The invention according to claim 1 is as follows: -Unlike the conventional one in which the pedestal is provided upright in the center of the lower surface of the quadrilateral top plate, which does not allow the user to freely move the foot. Since the lower end of the pillar is attached to the base of the supporting leg that opens in a V shape toward the front by tilting forward, there is room for the user to freely move his / her foot left and right.

Since the upper end of the lifting device built into the pedestal that is tilted forward is fixed not to the center of the top plate but to a position near the rear edge, even if the top plate is small, the knee The space under the top plate can be wide so that you can move things freely. The pedal for operating the lifting device is convenient because it is provided on the front side of the central portion of the base so that it can be operated by either the left or right foot.

[0019] through the top plate of the ordinary of the quadrilateral, too far away from the user, because there as the left and right almost triangular cut the corners of the back of the hard-to-use top plate, easy-to-use small and light elevating table can get.

[0020] is et al., Nearly the long side portion of the top plate of the triangle, because it is recessed toward in an arc toward the rear, ergonomic use goodness is obtained for the user, and high aesthetic value is obtained To be

The invention according to claims 2 to 4 : The operation is easy and simple.
