Definitions

  • the invention relates to a seat device with a support element according to the preamble of claim 1 (see DE-A-42 10 098, Figure 5).
  • a chair usually has four legs, a seat and one Backrest on. There are also one leg chairs that sit on one on the floor standing support element are attached.
  • the support element In the office furniture area, in particular Office chairs, the support element consists of a five-star supported by casters. and the seat height is adjustable by means of a telescopic adjustment of one leg.
  • the seat itself is not movable. Recently there is a seat device in which the tubes of the telescope are rotatable relative to one another are, which allows the seat surface slight circular movements. The stand area however, this chair is not stable enough to allow larger movements.
  • the present invention is based on the object of a seat device Specify at which the correct sitting position is automatically assumed and strengthening the back muscles.
  • the seating device should also be ergonomic and therapeutic requirements are sufficient.
  • the seating device according to the invention has the great advantage that light springing up and down movements can be made, which is an essential Relieve the back. You can also make slight circular movements be done, which is particularly prophylactic against possible Back damage is achieved by now actively strengthening the back muscles becomes.
  • the seat device according to the invention it is automatic the upright sitting posture, because a wrong posture is noticeably more uncomfortable is and must be corrected immediately.
  • Another advantage of the invention Seat device is that its manufacture is particularly inexpensive and is therefore affordable for everyone.
  • FIG. 1 shows a seat device 1 not according to the invention with an elastic support element 2, a Support leg 3 and a seat element 4 partly in cross section and partly in Shown top view.
  • the elastic support element 2 consists essentially of an upper circular disc 6 and a lower circular disc 7, the over flexible bands 8, for example hard-wearing textile bands, together are connected, and from a toroidal support body, in particular Tire 9 with an inner tube 10.
  • the tire 9 can be made of a thermosetting Material like polyurethane or from an elastomer like natural rubber or silicone rubber.
  • the discs 6 and 7 were on the outside a widened edge 11 or 12, which is on the upper or lower Tire bead 16 and 17 supports.
  • the flexible bands 8 are by means of rivets 14 or the like attached to the discs 6 and 7 and determine the greatest distance between the discs 6 and 7.
  • the tire 9 disks 6 and 7 pressed apart, i.e. they are mobile with each other stored.
  • the leg 3 is through a circular passage 18 of the disc 6 passed and has one on the inside attached circular disc 19 on.
  • An annular disk 10 is provided on the outside, which are pushed precisely onto the support leg 3 and by means of screws 21 is connected to the circular disk 19.
  • the support leg 3 is rigid, i.e. in a fixed angle of 90 °, connected to the support plate 6.
  • the metallic Support leg 3 has at its upper end region 22 - not visible here - Internal thread in which a spindle 23 is screwed, which in turn with the seat element 4 is connected.
  • the seat element 4 consists essentially of a circular disk 26 fastened on a saddle carrier 25 (cf. FIG. 3).
  • the Saddle carrier 25 has a bent pipe section 28 made of metal, for example is fastened to the spindle 23 by a welded connection.
  • On one End 29 of the pipe section 28 is a quick clamp connection 30 with a Lever 31 provided.
  • In the pipe section 28 is a bent with the same radius longer tube 33 is provided, which has saddle-shaped fastening plates at its ends 34 has.
  • the pipe section 28 and the pipe 33 thus form a tilt adjustment for the seat element or the saddle 4 Circular disc 26 attached to the saddle carrier 25.
  • the saddle 4 continuously in different positions (shown in dashed lines) adjustable and fixable.
  • the attachment can also be similar to a bicycle saddle locked in different positions and by means of a screw and mother are fixed.
  • the circular disc 26 is made of a durable material, such as leather, and has four parallel slots 38 (see FIG. 4). If this circular disk 26 is pressed in the edge areas 39 in the axis 40 parallel to the slots 38 with a certain force F 1 (FIG. 4b) and also laterally with a force F 2 (FIG. 4c), a saddle shape is created. 4c shows a cross section along the line AA in FIG. 4b. The more the two edge regions 39 are pressed together, the more pronounced the saddle shape. Thus, the distance between the two mounting plates 34 and their rounding together with the diameter of the circular disc 26 determines the final saddle shape.
  • the support leg 3 can be forward and tilted backwards (shown in broken lines in FIGS. 1 and 2), the tire 9 these movements depending on the internal pressure more or less limits. Because of the circular symmetrical design of the support element 2, no direction of movement of the support leg 3 is preferred and the seat device can 1 can also be moved in a circular motion. When extreme tipping movements are made, in which the tire 9 is even partially lifted off the ground the tire 9 offers sufficient stability on the ground, i.e. the chair can almost not slip away, as is the case with the usual rubber balls.
  • the Seat device 1 can actually roll on the tire 9, there is no transition from a tilting moment, as is the case with one-legged chairs with a flat plate Supporting element is common. Due to the special design of the seat 1 the back is always at least approximately in the axis of the support leg 3, so that the correct sitting position is automatically assumed, i.e. the user always makes small circular movements that strengthen the Cause back muscles. By the correct pressure of the tire 9 is a smooth transition between slight circular movements and larger circular movements receive. The slight circular movements or rocking up and down movements are perceived as very pleasant because the user is always moved around an equilibrium position. Give the larger circular movements a feeling of insecurity on the balance mechanism, so this rather be avoided. This forces the user, if possible - with a few Exceptions - to take the correct sitting position.
  • FIG. 5 shows a variant according to the invention in top view and in FIG. 6 in cross section of the elastic support element 2, wherein the toroidal support body or tire 9 between a flat disc 42 and a thick, light domed disc 43 is clamped.
  • This washer 42 is by means of screws 44 fastened on the thick disk 43 so that the two disks 42 and 43 form a kind of rim.
  • the disk 42 is approximately at the level of the Center of the tire 9 arranged so that there is enough ground clearance to to allow rocking movements of the chair, in a version not according to the invention discs 42 and 43 can both be flat steel discs with the same Be designed diameter.
  • the right movement characteristics can through the correct choice of the disc diameter of discs 42 and 43 and due to the ground clearance of the tire 9 and its hardness (air pressure) optimal on the Users can be set.
  • FIG. 7 there is also a top view and in FIG. 8 in cross section Variant of the elastic support element 2 not shown according to the invention, in which the tire 9 is designed as a rubber ring 45.
  • the rubber ring 45 can be made of solid rubber exist or be hollow inside, possibly with a valve is provided to adjust the air pressure in the rubber ring 45 and thus the hardness of the rubber ring to be able to determine.
  • This rubber ring 45 is now a convex in an annular groove 46 Washer 47 inserted, the annular groove 46 over an angle of something is greater than 180 °, for example 190 °, so that the rubber ring 45 is held by the slightly inwardly projecting edges 48 of the annular groove 46.
  • In the disc 47 is also a central hole 49 with a tube 50 with an internal thread provided for the mainstay not shown here.
  • FIG. 9 shows a further variant of the support element 2, however, without a tire 2 shown.
  • the support element 2 here consists of an upper disc 80 with a Larger diameter and a lower disc 81 with a smaller one Diameter.
  • the two disks 80 and 81 are made of stainless steel, for example Steel and each have a central bore 82 and 83 through which a conical Pipe section 85 passes through.
  • the pipe section 85 is in the area the central bores 82 and 83 are welded to the two disks 80 and 81.
  • the pipe section 85 is in the area of the central bores 82 or 83 welded to the two disks 80 and 81.
  • FIG. 9 A further variant of the arrangement of the support element 2 is similar in FIG as shown in Figure 9.
  • a through a central bore 87 Screw 88 pushed through the lower disk 81 and welded to it.
  • a central bore 90 in the upper disk 80 and on the opposite side a nut 92 is welded to it.
  • a slightly conical pipe section 93 with an internal thread 94 on the upper Disc 80 welded is welded.
  • the distance between the both discs 80 and 81 can be set.
  • FIG 11 is a side view and in Figure 12 partially in cross section an inventive seat device or one-leg chair 1 with the elastic support element 2 in the execution of Figures 5 and 6 shown.
  • This chair has an adjustable one Seat element 52, the middle part 53 and by means of hinges 54 or the like has articulated with this attached side wings 55.
  • the leg 57 is formed as an encapsulated gas pressure spring known per se, which consists of a Standpipe 58, a telescopic tube 59 and a plunger 60.
  • the cylinder the gas pressure spring is housed in the standpipe 58.
  • a tubular extension 63 with an external thread 64 is provided at the top 62 of the standpipe 58.
  • the standpipe 58 and the cover tube 66 can be made of a steel tube getting produced.
  • the standpipe 58 and the cover tube appear particularly elegant 66 made of wood, especially plywood, and the two end regions are provided with a metal cap, preferably made of stainless steel.
  • These two tubes 58 and 66 have a very high mechanical stability, which is why they ensure the necessary mechanical stability.
  • On the tubular Extension 63 is an inner ring 70 screwed with an internal thread is in turn attached to the inside of the cover tube 66.
  • a spiral spring 72 on the one hand with the outer ring 67 and on the other hand with the inner ring 70.
  • This coil spring 72 acts as the lowest height setting of the chair Compression spring and in the highest setting as tension spring.
  • eyelets 74 are also provided, and between the eyelets 68 and 74 circularly curved connecting rods 75.
  • a carrier 76 for the seat 52 attached to the telescopic tube 59, i.e. on the middle part 53.
  • the carrier 76 consists of a slightly curved connecting plate 77 and a U-shaped Round rod 78 with two parallel, circularly curved legs 79, on which the middle part 53 is supported.
  • the two curved legs 79 are welded to the connecting plate 77.
  • the connecting plate 77 has one Longitudinal slot on, which makes the carrier 76 slidable and by means of a screw nut or wing nut can be fixed on a threaded rod of the telescopic tube 59 is arranged so that the relative inclined position of the seat 53 is set can be (see Figure 12).
  • the functioning of the adjustable seat element 52 is now as follows: In the lowest position of the standing leg, the side wings 55 are through the as Compression spring acting coil spring 72 and the connecting rods 75 upwards pressed, i.e. there is a flat seat (position A - shown in dashed lines). If the telescopic tube 59 is now moved upward by the gas spring, so the coil spring 72 expands, but over a much shorter path than that Telescopic tube 59 so that the side wings 55 over the connecting rods 75 be pulled down slightly (position B - drawn in full). Becomes the telescopic tube 59 moves all the way up, the coil spring 72 are apart pulled so that it now acts as a tension spring and the side wings 55 all the way down (position C - drawn in dashed lines).
  • the coil spring 72 thus causes the balance between the substantially larger path of the telescopic tube 59 and the much smaller path of the two side wings 55, i.e. Has a buffer effect.
  • the coil spring 72 and the connecting rods 75 thus form a kind of mechanical translation.
  • the setting of the spring pressure of the coil spring 72 in position A can be adjusted by means of the inner ring 70, by rotating the support element 2 with the standpipe 58 with the extension 63. This allows the distance between the inner ring 70 and the outer ring 67 be enlarged or reduced, whereby the coil spring 72 more or less is compressed.
  • the various adjustable ones are shown in FIG Heights of chair 1 not immediately apparent. Furthermore, the usual Levers provided in the area of the seat element 52 are not shown here.
  • the tire 9 is not necessarily an inner tube 10 needs to have, but with a suitable seal between the two disks 6 and 7 can also be designed tubeless.
