    The invention relates to a chair mounting structure.
    Office chairs such as saddle chairs are known in the art where the chair structure comprises a pedestal and a gas spring attached thereto, which is further connected to the seat portion such as the saddle through the mounting structure.
    A known technique is the use of a gas spring to adjust the height of the chair seat portion as a foot portion of the chair. In this case, the gas spring is a telescopic cylinder and comprises a piston portion and a shut-off valve therein. by opening the shut-off valve, the pressure medium is lowered from the pressure side of the spring past the piston and shut-off valve to the other side of the piston and act on the end of the outermost telescopic cylinder part, thereby displacing it. The valve is closed / opened via the end of the cylinder head via the valve handlebar.
    When the button is pressed, the seat foot moves upward. When the button is not touched, the foot is locked in a certain height position. In a way, the gas spring is charged in its initial position by lowering it by sitting on a chair seat. The weight of the person will overcome the thrust of the cylinder by about 300 Newton and the valve will be kept open. The seat unit lowers.
    The outer end of the gas spring is conically connected to the taper hole of the foot, and correspondingly the thicker lower end of the gas spring is connected to the tapered hole by a tapered joint. In this application, the other end of the gas spring is connected by a conical connection to a cone and to an inner conical bore of the sleeve portion of the threaded portion.
    In general, in prior art solutions, the foot and gas spring fastening structure to the chair portion has involved a complex fastening arrangement and welding.
    This application discloses a simple fastening structure where welding is avoided.
    The application discloses the use of a guide and threaded portion 30 in the fastening structure comprising a flange and a hollow sleeve of smaller outer diameter comprising outer threads on the surface of the sleeve portion. The inner bore of the sleeve is conical and engages a gas spring end which is also conical.

    The sleeve is inserted through the center hole of the first body portion so that the flange of the sleeve contacts the edges of the center hole.
    The structure comprises a spacer ring, for example, of rubber. It is placed between the second plate-like body and the first body. The other part of the frame 5 has the shape of a circle. The circular plate comprises a central hole. The material is preferably metal.
    The clamping nut is inserted into the threads of the sleeve member. Turn the nut to squeeze the spacer ring between the first and second frame members. Preferably a second nut is also used which acts as a locking nut. The spacer is made of rubber or, in general, of a flexible material, thus giving the joint a dynamism.
    The structure further comprises a frame member whose function is to lock the pivot lever in its frame portion and guide it in the groove of the frame portion and to hold it between the guide slots. Turning the lever outwardly pushes the gas spring valve actuator button 15 which extends from the center hole of the first body member to the recess of the body of the first body member.
    The structure also comprises an outer guardrail that engages the edge of the second frame member. The structure also comprises a sealing ring around the sleeve portion between the sleeve portion flange and the first housing portion in a recess of the first housing portion 20 around its central hole.
    The first and second frame members and the frame are fastened in one package to the seat portion of the chair by screws.
    The chair mounting structure of the present invention is characterized by what is claimed.
    The invention will now be described with reference to some preferred embodiments of the attached figures, which are not, however, intended to be limited thereto.
    Figure 1 shows a saddle chair.
    Figure 2 is a cross-sectional view of the fastening structure.
    Fig. 3 is a separate view of an important part of the invention with a conductor sleeve.

    Fig. 4 is an exploded view of the attachment structure of a seat portion of a chair according to the invention.
    Figure 1 shows a chair 10 comprising a fastening structure 11 between the seat part 12 5 and the foot 13 according to the invention.
    The chair 10 is preferably so-called. a saddle chair comprising a seat portion of 12 saddles. The foot 13 is a conventional gas spring used in the head 14, known in the art.
    By actuating the gas spring knob 14, the valve in the spring piston portion ίο is opened and closed and the outer and small diameter cylindrical portion of the telescopic gas spring is moved. This adjusts the seat height.
    The gas spring is secured by a conical connection in the cone hole of the chair footrest 15 and by a conical connection in the conical hole in its guide sleeve in the fastening structure.
    Fig. 2 shows a guide sleeve 16 for the seat assembly of the seat assembly according to the invention. It comprises a flange 17, a center hole 18 in the sleeve portion 16 and threaded 16b on the outer surface of the sleeve portion which engages clamping nuts 19. The center hole 18 is conical
    As shown in Figures 2 and 3, by tightening the nuts 19, the guide sleeve 16 is clamped against its flange 17 to the edges of the center hole 22 of the recess 21 of the first body 20 and retains the spacer 23 between the first body 20 and the second body 24. The second body portion 24 comprises a central hole 25.
    Between the edges of the center hole 25 of the flange 17 there is a resilient sealing ring 30.
    The frame member 26 engages the first body member 20 and between the seat member 12 and the first body member 20. Screws 27 fasten the structure to the chair seat portion 12.
    The function of the frame member 26 is to hold the pivot lever 28 in the structure and in connection with the guide slots 29 of the first body member 20. The pivot lever 28 acts to pivot it to the actuator button 14 of the end of the gas spring 13, opening the stop valve inside the gas spring 13 through the mandrel.

    Fig. 4 shows the fastening structure 11 separately. The first body portion 20 is uppermost in the figure. The conductor sleeve 16 comprises outer threads 16a and an inner taper hole 18 for the tapered end 13a of the gas spring 13. The guide sleeve 16 comprises a flange 17 in its sleeve portion 16a for engaging the first body portion 20. Shown are tightening nuts 19 in the outer threads 16b of the sleeve 16a of the sleeve portion 16. The upper acts for clamping and the lower acts for locking. By rotating the nut 19, the second body portion 24, the spacer ring 23 and the first body portion 20 are compressed into a single package. The sealing ring 30 is located around the sleeve portion sleeve 16a below the flange 17 and is pressed against the edge of the center hole 22 of the first body portion.
    The spacer ring 23 extends between the first body member 20 and the second body member 24. The first body portion 20 and the spacer ring 23 and the second body portion 24 comprise through the center through holes 01,22,25 a foot 13, preferably to a gas spring end 13a. The spacer ring 23 is preferably made of rubber or other resilient material. One of its functions is to give the structure and seat part 12 dynamic elasticity.
    Outermost in the structure is a rubber bellows 29 which is secured to the edge of the second body member 24. The spacer 23 and the sealing ring 30 are preferably made of a resilient material such as rubber.
    In a preferred embodiment, the larger rubber ring 23 may have an outer diameter of 30 to 80 mm, preferably 40 to 60 mm, and most preferably about 48 mm. Correspondingly, the smaller rubber ring may have a height of 3 to 15 mm, most preferably 25 to 10 mm, and most preferably about 5 mm. The smaller rubber ring may have a corresponding height of 4 to 25mm and most preferably 5 to 15mm and most preferably 7.3mm.
    The optimum rubber SHORE hardness (smaller ring) is 40 to 80, most preferably 50 to 70, most preferably about 60. Similarly, the larger rubber ring hardness (SHORE value) is 30 to 80, preferably 40 to 60 and most preferably about 50.
    An optimum width of the first body portion 20 is 80 to 150 mm, preferably 100 to 140 mm, most preferably about 123 mm. However, the dimensions can be adjusted in their entirety so that the parts fit in place and sufficient strength is achieved.
    One optimum width of the second body portion 24 is 90 to 140 mm, preferably 100 to 125 mm, most preferably about 115 mm. However, the dimensions can be adjusted in their entirety so that the parts fit in place and sufficient strength is achieved.
