Definitions

  • the present invention relates to a locking device for an office chair, in particular for an office chair, in which the backrest is articulated with respect to the seat surface, so that it is optionally tiltable with respect to the seat surface, which simultaneously moves forward while the backrest tilts backwards .
  • the seat and the backrest are connected so that the seat slides forward in a prescribed path depending on the tilting of the backrest. This is also called “synchronous" seat and backrest adjustment.
  • Such an office chair is described in DE-PS 33 13 677.
  • the necessary locking forces can be achieved be minimized in order to hold the seat and backrest elements securely in their specified position.
  • the invention has for its object to provide an effective and simple locking system for use in connection with the support system described.
  • the support frame for the seat and back of the office chair has a front cross arm that holds a slide / lock member in place to effectively apply a pair of laterally spaced inwardly slotted housings in which the slide / lock member rests emotional.
  • the sliding / locking element is rotatable between a first sliding position and a second locking position with the opposite slots.
  • the sliding / locking element has a non-circular cross section.
  • the larger dimension of the sliding / locking element is oriented in the direction of the movement, while in the second or locking position the larger dimension of the sliding / locking element is subjected to frictional action is moved between the walls of the housing which forms the slotted opening.
  • this type of locking system can only withstand an adjustment force of approximately 200 Newtons due to the unique suspension system described above, this is by far sufficient to securely lock the chair in a predetermined position.
  • FIG. 1 an office chair is shown, which essentially has a seat assembly 10, which has a curved backrest 12 and a seat recess 14, which are hinged together and are adjacent on the lower edge of the backrest 12 and the rear edge of the seat recess 14.
  • a base is formed by a plurality of legs 16 that extend radially outward from a central portion and end in support rollers 18.
  • An adjustable vertical column 17 extends upwards from the base and has a support frame 20 (FIGS. 3 and 4) arranged thereon, which is located below the seat 14.
  • a pair of side arms 22 are attached to the support frame 20 and pivotally support the seat assembly 10.
  • the backrest 12 and the seat pan 14 are supported on the base by a support frame or system 20.
  • the backrest 12 comprises a lower lumbar region, and the backrest 12 and the seat recess 14 are connected to one another in an articulated manner in the hinge point 13.
  • the backrest 12 and the seat recess 14 are suspended above the support frame 20 on the side arms 22, which at their lower ends on one transverse support arm 30 are attached, which forms the rear portion of the support frame 20.
  • the arms 22 pivotally support the backrest 12 at point 28.
  • the backrest seat component could normally swing or rotate about point 28, but this is prevented by a front connecting element 24 which slidably connects the front portion of the support frame 20 to the lower front portion of the seat pan 14 and locks them together.
  • the seat is freely tiltable depending on the pressure applied against the upper portion of the backrest 12.
  • the connecting element 24 is locked, such a tilting movement is prevented.
  • a relatively small locking pressure or a small locking force (around 200 Newtons) is sufficient to lock the backrest seat assembly in the locked position Hold position, since the pressures that want to remove the seat from its locked position are relatively low.
  • a support frame 20 is provided, which is best seen in FIGS. 3 to 5.
  • the support frame 20 is arranged on the upper end of the vertical support column 17 and is essentially by a transverse support arm 30 formed, a shorter cross arm 32 and a main housing 34 which connects the transverse support arm 30 and the cross arm 32.
  • the transverse support arm 30 is arranged at the rear end of the support frame 20, directly above the vertical support column 17, while the shorter cross arm 32 extends transversely below the front section of the seat recess 14. Both the support arm 30 and the cross arm 32 are hollow to accommodate various control components.
  • a lever handle 54 is pivotally attached to the transverse support arm 30.
  • the tubular rod 56 connects the lever handle 54 to the rear crank 58 of a connection that passes through the main housing 34.
  • a connecting arm 60 connects the rear crank 58 to a front crank 62.
  • the front crank 62 is operatively connected to an actuating rod 64 of a slide / lock element 66. Rotation of the lever handle 54 also rotates the link of 58, 60 and 62 to rotate the actuating rod 64 and the slide / latch member 66 through a prescribed arc.
  • connection which slidably connects the cross arm 32 of the support frame 20 to the front portion of the seat pan and locks them against each other if necessary.
  • a pair of spaced apart slotted housings 72 and 74 are attached to the underside of the seat 14.
  • Each housing 72, 74 includes an inwardly elongated slot or a track 76, which is opposite the adjacent extreme, and thus the sliding / locking element 66, of the cross arm 32.
  • the sliding / locking element 66 is shown hexagonally shaped.
  • the diameter between the surfaces of the hexagonally shaped element is substantially equal to or slightly less than the width of the slot or track 76. Therefore, when the hexagonally shaped sliding / locking element 66 is aligned in a first sliding position in which its surfaces are parallel to run along the walls of the track 76, the sliding / locking element allows a relative movement between the housing 72, 74 and the cross arm 32.
  • the effective diameter of the slide / latch member 66 increases and is larger than the space between the walls forming the track 76. In this position, the larger diameter then effectively and frictionally acts on the side walls of the slot 76 to lock the slide / latch member 66 in place, thereby preventing the seat 14 from sliding and the backrest 12 from tilting in either direction.
  • the frictional force required to prevent movement of the chair in both directions is relatively small (on the order of 200 Newtons compared to 800 Newtons for other types of chairs).
  • the slide / latch element 66 is shown as a hexagonal element, each causes non-circular Design the desired effect as long as the element has a larger effective diameter when rotated to a first position than corresponds to the second effective diameter in a second position.
  • the sliding / locking element 66 could therefore theoretically be formed octagonally, at right angles or elliptically in cross section.
  • the hexagonal shape appears to be a good compromise, since it causes a larger effective diameter difference than would be the case with a larger number of corners, and it only requires a 30 ° movement of the lever handle 54 to effect such a locking movement .
