Description

Seat plate sliding structure {Structure for sliding of seat}

The present invention is to allow the seat plate of the chair to be slidable back and forth. Specifically, according to the difference in the height of the seat occupant, the seated person can freely manipulate the seat plate by sliding the lever back and forth by sliding the lever provided at the lower side of the seat plate. It relates to a seat plate sliding structure that allows the seat plate to slide back and forth to fit the body structure such as a difference.

Conventionally used chairs are fixed, and chairs used in offices, schools, buses, and the like have been used with a backrest and a seat plate fixed.

These chairs cause user fatigue and malaise when used for a long time.

In general, when the user tries to rest by leaning on the back of the chair, the user's hips move forward. These postures are cases where the user's body is not in close contact with the chair's back and seat, and fatigue is easily felt, and people who complain of back pain, such as low back pain, are applied to the spine due to an incorrect posture.

In addition, people who work in the office job has been sitting on a chair for a long time working on the spine due to the back disease, such as disk has been generated.

In addition, due to the difference in the height of the seat occupant because the depth of the seat plate does not fit the body structure of the seat is also likely to cause diseases related to the waist.

In order to solve these problems, recently, chairs for waist protection based on ergonomics have been developed one after another and come out as prototypes.

However. These chairs also have a solid backrest and seat plate attached to the backrest, and the user must consciously attach the waist to the backrest, and the hips should be pressed against the seatboard. Also, the hips were leaned toward the front of the chair, causing him to work in a bad posture.

Looking at the technical gist of Utility Model Registration No. 0304618 as a technology to solve this problem,

Reference numeral C denotes a chair.

Briefly describing the operation of the present invention configured as described above,

First, when the coupling state is described, as shown in FIGS. 1 and 2, the sliding plate 20 and the fixed plate 30 are sequentially coupled to the lower end of the seat 40.

Looking at the coupling process of the sliding plate 20, the fixed plate 10 and the operating lever 30, as shown in Figure 2, the inner wall of the '' 'shaped partition 200 provided in the sliding plate 20 As the fixing plate 10 is internally coupled, the stepped portion 100 of the fixing plate 10 is coupled to the guide member 201 for preventing the separation of the sliding plate 20 so as to slide together.

After the fixing plate 10 is coupled to the sliding plate 20 as described above, the other end of the spring 204 having one end coupled to the fixing part 203 of the sliding plate 20 is fastened to the fixing plate 10 104. )

In the above state, the operating lever 30 is inserted through the cutout hole 205 of the sliding plate 20 and continuously inserted into the groove portion 203, and then the operating lever in the fastening groove 103 of the fixing plate 10. After the stop protrusion 301 of the 30 is fastened, the hook 206 of the sliding plate 20 is connected to the other end of the spring 304 having one end fixed to the fixing protrusion 303 of the operating lever 30. It can be fixed fixedly.

In the assembled state as described above, the operation will be described.

As shown in FIG. 3, the stop protrusion 301 is fastened to the fastening groove 103. In this case, the seat 40 is not fixed back and forth.

Next, as shown in FIG. 4, when the seated person pulls the operation lever 30, the stop protrusion 301 is released from the fastening groove 103, and the maximum release range is the stopper 302 of the operation lever 30 guides. The operation lever 30 is no longer pulled by the other side of the ball 102.

As shown in FIG. 5, the seat 40 is moved back and forth when the seated person pushes the seat 40 back and forth while supporting the back plate as shown in FIG. 5.

If the seat 40 is moved to the desired position as described above, the release projection 301 of the operating lever 30 automatically stops when the release lever 30 is pulled using the handle part 300. Is fastened to the fastening groove (103) of the seat will be able to slide the seat 40 back and forth to the desired position.

6 shows such a state.

 The present invention as described above is to be able to simply fixed by moving the seat back and forth according to the user's body shape, so that users of various body types can be comfortably seated in the chair.
