[

Let's take a look at the concrete contents for designing considering the order in which the parts of the chair are assembled. The seat 100 of the chair can be manufactured in various forms for the user to sit on. When the fixing screw 202 for fixing the seat support member 200 to the bottom surface of the seat 100 is sharp and the end portion of the seat is sharpened so that it can be inserted into the bottom surface of the seat 100, It is not necessary to drill another hole in the fixing screw 202. However, in the case of the fixing screw 202 having a blunt end, a separate insertion nut may be provided by drilling the bottom surface of the seat 100. [

The seat plate fixing member 200 is formed with a flange 201 having a screw hole around the upper end of the body so as to be fixed to the bottom of the seat plate 100 with a fixing screw 202, And a receiving portion 203 for receiving the upper end portion of the connecting member 300 is formed in the lower center of the lower portion of the body. The height adjusting lever 203, which is installed on the outside of the body and the inner space, (204).

The connecting member 300 is composed of the cylinder 301 and the piston 302 so that the upper outer circumferential surface of the piston 302 contacts the inner circumferential surface of the storage portion 203 of the seat plate fixing member 200 and is engaged with the seat plate fixing member 200 And the length is adjusted by the operation of the height adjusting lever 204 of the seat mounting member 200. Gas springs commonly used in chairs are good examples of connecting members.

The inner circumferential surface of the connecting member receiving portion 401 formed inside the upper end portion of the upper support member 400 receives the outer circumferential surface of the lower end of the connecting member 300 and is engaged with the connecting member 300, And a connecting member support step 402 is provided at the bottom to support the bottom surface of the connecting member 300. A concave portion 404 which is a space for accommodating the stopper 701 at the upper end of the tension bolt 700 below the connecting member supporting jaw 402 is provided. When the stopper 701 at the upper end of the tension bolt 700 received in the recess 400 is moved together with the movement of the body of the tension bolt 700 while the upper support member 400 is engaged with the connection member 300, The concave portion 404 is formed in the concave portion 404 when the stopper 701 received in the state in which the stopper 701 at the upper end of the tension bolt 700 is accommodated is moved so as not to interfere with the wall surface of the connecting member 300, It is necessary to have a sufficiently deep and wide clearance space so as not to be interfered with the wall surface of the connecting member 300 or the bottom surface of the connecting member 300. An upper guide hole 405 is formed in the center of the concave portion 404 so as to insert the tension bolt 700 into the upper support member 400 in the axial direction of the body of the upper support member 400, The upper guide hole 405 is narrower than the diameter of the upper end stopper 701 of the tension bolt 700 and wider than the diameter of the body of the tension bolt 700, 405 and the body of the tension bolt 700. When the tension bolt 700 moves within a predetermined angle in the forward, backward and leftward and forward directions in accordance with the movement of the spring 500, Mutual interference does not occur between the wall surfaces of the upper guide hole 405. However, when the movement of the spring 500 and the tension bolt 700 becomes larger than a predetermined range, interference occurs between the body of the tension bolt 700 and the wall surface of the upper guide hole 405, The movement of the spring 500 and the tension bolt 700 is controlled within a certain angle. The limit of the flow angle at which the spring 500 and the tension bolt 700 can move is determined by the clearance distance between the wall surface of the upper guide hole 405 and the body of the tension bolt 700, There is a relationship. Since the periphery of the concave portion 404 of the upper support member 400 is wider than the circumference of the upper guide hole 405, a stopper supporting jaw 403 is provided between the boundary of the lower end of the concave portion 404 and the boundary of the upper end of the upper guide hole 405 The stopper supporting jaw 403 supports the bottom surface of the upper stopper 701 of the tension bolt 700 to prevent the stopper 701 on the tension bolt 700 from escaping through the upper guide hole 405 do. An upper end of the spring 500 is inserted into the upper end of the spring receiving portion 406 to receive the upper end of the spring 500, do.

The spring 500 uses a compression spring in the form of a round coil having a strong tension.

The lower support member 600 is formed with a taper reducing the diameter of the body as it goes downward on the outer circumferential surface of the body, a spring lower end receiving portion 601 formed in the body upper portion to engage with the spring 500, 601 is formed on the bottom of the support base 602 to contact the bottom surface of the spring 500. In addition, an adjusting nut accommodating portion 604 for accommodating the adjusting nut 800 is formed in the lower portion of the body, and a lower guide hole 603 penetrating the center of the body in the axial direction is provided. The spring lower receiving portion 601 and the adjusting nut receiving portion 604 share a supporting jaw 602. The body of the tension bolt 700 penetrating the upper support member 400 in the axial direction and penetrating the spring 500 in the axial direction passes through the lower support member 600 again in the axial direction, ) To combine all of them to form one minor axis with fluidity. At this time, there is a clearance between the lower guide hole 603 of the lower support member 600 and the outside of the body of the tension bolt 700, so that the tension bolt 700 is moved in a forward, No mutual interference occurs when moving. The movement of the spring 500 and the tension bolt 700 becomes larger than a certain range and the movement of the tension bolt 700 and the lower guide hole 603 Interference occurs between the wall surfaces and the movement of the spring 500 and the tension bolt 700 is controlled within a certain angle. The limit of the flow angle at which the spring 500 and the tension bolt 700 can move is determined by the clearance distance between the wall surface of the lower guide hole 603 and the body of the tension bolt 700, There is a relationship.

      The tension bolt (700) has a thread formed on the outer surface of the lower end of the body and has a diameter

The large stopper 701 does not need to have threads formed on the entire outer surface of the body with the bolt provided at the upper end thereof. However, the lower end of the bolt must have threads formed on the surface thereof so as to be able to engage with the adjustment nut 800 having a female screw. It should be male.

The adjustment bolt 800 having the threaded portion formed therein is received in the adjustment nut receiving portion 604 of the lower support member 600 and engaged with the tension bolt 700.

The lower end outer peripheral surface of the lower support member 600 having the tapered outer peripheral surface thereof is in contact with the inner peripheral surface of the central shaft receiving portion 901 of the bottom support member 900 having the tapered inner portion. Each floor of the support feet 902 extending radially from the center supports the entire chair while supporting the floor.

A cylindrical upper end insertion portion 407 is formed at the center of the spring upper end receiving portion 406 of the upper support member 400 with an inner circumferential surface of the upper guide hole 405 as an inner circumferential surface to insert the upper end insertion portion 407 into the upper end inner peripheral surface of the spring 500 And a cylindrical lower end inserting portion 605 is formed at the center of the spring lower end receiving portion 601 of the lower support member 600 so that the interface of the lower end guide hole 603 is an inner circumferential surface, The upper support member 400 and the lower support member 600 are more reliably prevented from being separated from the spring 500 and the height of the upper end insertion portion 407 and the lower end insertion portion 605 are appropriately set The flow angle of the central axis can be adjusted as desired.
