Description

The present invention relates to a sitting chair that can sit while standing.

As a chair of this type, there is a chair according to the proposal of the present applicant (Patent Document 1). The pelvis is supported by a hemispherically-shaped cushion of a saddle-type cushion seat cushion surface which is sandwiched between the crotch, and the rotatable caster is stabilized by the spring post, the seat lands when the spring contracts by about 10 mm if weight is applied, When the weight is transferred to the foot and the waist is lifted, the caster lifts the pedestal and works, holding the saddle, rotating and moving freely.

In addition, there is a chair with 3 to 4 legs and a chair to sit on in a conventional work chair, but 3 to 4 legs take up a place in the work place where the flow line is important, and the knee length when sitting still A minute must be kept away from the work area, and you have to stand up in order to work, and there is a chair at the back, so there was a drawback that it would be dangerous if you did not check the chair when you sat.

Jouhei 5-76365

The chair in (Patent Document 1) is weight-weighted when sitting on the crotch with the base in the crotch, and the caster does not move when the base is lowered by 10 mm, and the caster moves when the hip floats up, and it can rotate and move while holding the saddle. Although the chair operates with a little weight and the direction of the chair is determined only by the support of both legs, people with physical disabilities and people with slow movements such as old people support the body There is nothing unusual about it, and the base of the chair covers a spring post with a few casters at the lower part of the chair, which has a feeling of stability, but it takes up space because the chair can not be folded.

When you sit down, the upper body moves away from the work area by the length of the knee, so it is difficult to work while sitting, so check the chair because there is a chair behind you when you sit down. It is dangerous if you don't sit, and there are 3 or 4 legs of the chair, and there is a problem that it takes a place.
The present invention has been made to eliminate the above-mentioned drawbacks.

The chair is hooked to the workbench 5 and the hooking portion 1 is vertically provided at the tip of the support column 4 and bent in a perpendicular direction and hooked on the workbench 5 to work by bringing the body close to the workbench 5 In the structure, a rectangular plate 10 is attached 90 degrees horizontally to the lower part of the support column 4 for protecting the work table 5 so that the chair can stand independently even when the body is separated from the chair. When hooked, the pedestal 12 on which the support pillar 4 and the pedestal 13 are placed is connected by four connecting plates 6, 7, 8, 9 and sits on the pedestal 13 and the entire weight is supported by the pedestal 12 In the structure fixed to the work bench 5 with the support pillars 1 and 4, the pedestal pillar receiving portion 16 constituting the back side of the pedestal 13 is provided with a pedestal opening 17 whose side surface serves as a stumper, and the pedestal pillar 12 is By inserting it into the pedestal support 16 and fixing the central shaft 18 with a screw, When the person sitting on the pedestal 13 faces the left of the pedestal 13a, the pedestal 12 moves in the direction of the pedestal 12a, and when the pedestal 13b faces the right, the pedestal 12 is in the direction of the pedestal 12b. The height of the chair is comprised of a column support 15 provided at the bottom of the pedestal 12 and a height adjusting rod screw 14 provided between the pedestal 12; When the chair is folded up, when the hook portion 1 is lifted, the support column 4 and the pedestal 12 are closed to make one rod shape, thereby realizing a compact storage form and portability to indoors and outdoors.
The present invention is a hook chair for standing work comprising the above constitution.

  In the present invention, the structure is hooked to the work place, and since the work place is straddling forward on the work surface, the gap between the work place and the upper body is small, and the work can be performed without the worker being leaned forward.

  There is no danger of sitting on the work surface as the pedestal is not separated from the buttocks, so the pedestal moves at a certain angle in the left-right direction, and the upper body work range even if sitting spread.

  The support pillar with the hook and the pedestal on which the pedestal rests are connected by the connecting plate and the entire weight is supported by the pedestal, so that it is stable even when sitting on the pedestal and in long standing work There is less fatigue in the lower body.

  When the hooking part is hooked on the work bench, the support column and the pedestal column automatically open, and the pedestal column reaches the floor and becomes a single leg, so the movement line does not take up a place at the important work place.

  When the hook portion is lifted, the support post and the pedestal are closed to form a single rod, which achieves a compact storage configuration.

Hereinafter, embodiments of the present invention will be described.
(A) As shown in FIG. 1, the hooking portion 1 is attached to the tip of the support column 4, and the trapezoidal plate 3 to which the rubber plate 2 is stuck is fixed to the hooking portion 1.
(B) The rectangular plate 10 having the rectangular rubber plate 11 attached to the lower part of the support column 4 is parallel to the door of the work table at the time of use, and becomes parallel to the support column 4 as shown in FIG. It is provided.
(C) As shown in FIG. 4, at the center of the pedestal support 16 on the back surface of the pedestal 13, there is provided a pedestal opening 17 in which the upper and lower portions are hollowed.
(2) The pedestal 12 is inserted into the pedestal opening 17 and fixed with a screw from the center of the pedestal 13 to the position of the central axis 18, and the pedestal 13 moves left and right with the central axis 18 as a fulcrum. When 12 strikes the hour side of the pedestal opening 17, it stops.
(E) As shown in FIG. 1, when the base 13 is in the left direction of the base 13a, as shown in FIG. 4, the base 12 is in the direction of the base 12a and the base 13 is in the right direction of the base 13b. In some cases, the pedestal 13 and the pedestal 12 are configured to be in the direction of the pedestal 12 b.
(F) As shown in FIG. 1, the upper connection plate right 6, upper connection plate left 7, lower connection plate right 8, and lower connection plate left 9 are connected between the support column 4 and the pedestal column 12 This makes the hook chair more stable.
(G) Height adjustment when using a chair is configured by turning the support base 15 by adjusting the height adjustment rod screw 14 between the pedestal 12 and the support base 15.
According to the method of use of the present invention, when the hook portion 1 is hooked on the work table 5 and the base 13 is held and pulled toward the front, one rod-like support pillar 4 and pedestal pillar 12 are shown in FIG. Thus, the upper connecting part right 6, the upper connecting part left 7 and the lower connecting part right 8 and the lower connecting part left 9 are spread, and the pedestal 12 is fixed to the floor at a position just good for working from the work bench.
(I) As shown in FIG. 3, the height of the pedestal 13 is adjusted by rotating the support base 15, and the pedestal 13 is used astride the pedestal 13.
