Description

[Detailed Description of the Invention] The present invention relates to an examination table, and more particularly to an examination table which is foldable and easy to assemble.

Various types of collapsible examination tables have been proposed in the past, but conventional examination tables of this type have complex structures, are not easy to assemble, and have problems with their strength in the assembled state.

The present invention was developed in view of the above circumstances, and aims to provide an examination table that is simple in structure, foldable, and easy to assemble.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

The examination table, which is generally indicated by the reference numeral 1 in the figure, is assembled on the basis of a rectangular board 2 made of plywood or the like, as shown in an enlarged view in FIG. A side plate 3 is fixed to the back surface of the peripheral edge of the substrate 2 over the entire circumference, and a cushion material 4 is arranged on the upper surface of the substrate 2 and the outer peripheral surface of the side plate 3. Cover with synthetic resin sheet, etc. 5
is provided. The peripheral edge of this coating 5 covers the outer peripheral surface of the side plate 3, and staples 6 are folded back from the lower edge to the inside of the side plate 3 and driven at a predetermined pitch.
Fixed by

On the other hand, a plurality of reinforcing frames 7 are arranged at predetermined intervals on the lower side of the substrate 2 in a widthwise direction, and the reinforcing frames 7 are fixed by a supporting frame 8.

The support frame 8 is formed from a metal plate, and its length is slightly shorter than the length of the substrate 2. A wide portion 9 is formed at both ends of the support frame 8, and an outwardly extending portion having a width substantially equal to the thickness of the side plate 3 is formed at the end of the wide portion 9 on the lower edge side of the side plate 3. A bent portion 9a is formed which is bent at a right angle. This bent portion 9a is pressed against the lower edge of the side plate 3 from the outside of the folded covering 5, and the screw 10 is pressed against the lower edge of the side plate 3.
Fixed by Further, the wide portion 9 is also fixed to the inner surface of the side plate 3 with screws 10.

A fixing screw 11 is attached to the inner surface of the wide portion 9 at a position along the longitudinal edge side of the examination table 1.

That is, the fourth
As shown enlarged in the figure, a screw hole 12 is formed, and a threaded portion 11a at the tip of the fixing screw 11 is screwed into this screw hole 12.

Further, the fixing screw 11 has a hexagonal head 11b,
There is a nut 1 on the tip side that serves as a stopper.
3 are screwed together, and a spring washer 14 is fitted on the outside of this nut 13.

On the other hand, at both ends of the support frame 8 excluding the wide portions 9 and on the side edge on the board 2 side, there is a section that is perpendicular to the side opposite to the bent section 9a, that is, toward the inner side of the side plate 3. A bent portion 8a is formed, and this bent portion 8a is stacked on the reinforcing plate 7 and is attached to the substrate 2 together with the reinforcing plate 7 by screws 10.
Fixed.

Further, a midway portion of the support frame 8 is fixed to the inner surface side of the side plate 3 with screws 10.

On the other hand, what is indicated by the reference numeral 15 is a leg, and this leg 15
is a pair of left and right supports 1 formed from square pipes, etc.
6 and 16, and a reinforcing frame 1 is provided between the lower end portions of the reinforcing frame 1.
They are connected by 7.

The top of a substantially trapezoidal bracket 18 is fixed to the upper end of each column 16 by means such as welding, and a bolt 19 is attached near the tip of the protrusion 18a.
The support frame 8 is rotatably supported by a wide portion 9 at both ends of the support frame 8 at a position extending inwardly from the fixing screw 11 . The one indicated by the code 20 is bolt 1.
This is a washer interposed between the wide part 9 and the wide part 9.

Also, as is clear from FIG. 2, the bracket 18 extends beyond the upper end of the column 16, and is located at the end opposite to the bolt 19 and connected to the fixing screw 11.
A through hole 21 is formed in the wide portion 9 at a position opposite to the screw hole 12 into which the wide portion 9 is screwed.

Incidentally, as is clear from FIG. 4, the size of the support column 16 is such that it has a quadrilateral cross section in which the length of one side is shorter than the length of the fixing screw 11. That is, the thickness of the support column 16 is shorter than the length of the screw 11.

Next, a method of using this embodiment configured as above will be explained.

If you want to use the examination table 1, connect the legs 15 to the board 2.
Bracket 1
The through hole 21 formed in 8 is aligned with the screw hole 12 in the wide part 9 of the support frame 8, and the threaded part 11 of the fixing screw 11 is
a into the screw hole 12 through the through hole 21. At this time, the spring washer 14 is interposed between the nut 13 and the spring washer 14. Then, using a simple screwdriver (not shown), etc., fix the hexagonal head 1 of the fixing screw 11.
It is only necessary to completely tighten and fix the fixing screw 11 via 1b.

During this tightening operation, the fixing screw 11 is
Since it is in a state that protrudes more than 6, the fixing screw 11
does not enter the shadow of the upper end of the support column 16, and a simple spanner can be freely used outside the support column 16.

If you want to fold it, remove the fixing screw 11 using a wrench or the like, rotate the legs 15 to the board 2 side so that they overlap around the bolts 19,
Screw the fixing screw 11 into the screw hole 12 of the wide portion 9 again using your fingers or the like. If you do this,
There is no need to lose the fixing screw 11, which is an independent component, and there is no need to store or manage it. Further, since the fixing screw 11 is located in the space between the substrate 2 and the upper end of the support column 16, the fixing screw 11 does not interfere with use during use.

As is clear from the above explanation, according to the present invention, the legs of the examination table are rotatable, and the legs of the examination table are configured to be able to be maintained in an upright state by the fixing screws, and the length of the fixing screws is Since the legs are configured to be larger than the thickness of the leg supports, the legs do not get in the way when screwing in using a spanner, etc., making it easy to screw in and making assembly easier.

In addition, each support frame is fixed over almost the entire length of the examination table, and its width direction is perpendicular to the board, so it will not deform under the load applied to the examination table. , the examination table does not sag.
