Definitions
- the present invention relates to a mechanism for a chair with a gas spring for synchronously controlling the inclination of its seat and a backrest articulated thereon in a displaceable axis of rotation.
- the seat rests on a base placed on the floor.
- the gas spring is articulated on the one hand in an axis of rotation on the front region of the seat and on the other hand in an axis of rotation on the base frame.
- the mechanics allow the chair to be adjusted from its starting position - with a basically horizontal seat and vertical backrest - to a forward, negatively inclined writing position and a relaxing position that is inclined backwards .
- a further, vertically installed gas spring can be provided to vary the seat height.
- EP 0 592 369 B1 describes a synchronous mechanism for the adjustment of a Chair from a forward inclination through a normal position to one after in the rear tilted relaxation position. For this is a pair of coil springs between a fixed seat support and a multiple articulated one Seat support arranged. This mechanism has proven itself over the years however, a larger construction volume and is relatively complex, therefore assembly and costly.
- the invention has for its object a to propose simplified mechanics with adequate performance characteristics.
- the mechanism is intended for a chair with a first gas spring for synchronously controlling the inclination of its seat and a backrest articulated thereon in a displaceable axis of rotation.
- the seat rests on a base placed on the floor.
- the first gas spring is articulated on the one hand in an axis of rotation on the front region of the seat and on the other hand in an axis of rotation on the base frame.
- the first gas spring surrounds a sealed housing that encloses a gas chamber.
- a piston with the piston rod extending therefrom is arranged within the gas chamber to be axially displaceable to a limited extent.
- the piston rod extends away from the piston in the expulsion direction, while the diametrical axial direction is defined as the direction of insertion.
- a spring element is arranged in front of the piston in the expulsion direction.
- the piston is in the starting position, with a basically horizontal seat and a vertical backrest, on the spring element in a zero position, and when the concentration of weight on the front area of the seat, as caused by a user bending forward, the distance between the two, including the first gas spring, increases rotary axes.
- the piston thus acts against the spring element and can move beyond the zero position, in the opposite direction to the insertion direction, namely further in the direction of expulsion, over a path to an advanced end position.
- the front area of the seat lowers against the action of the spring element from the zero position into a negative position inclined towards the floor.
- the movement of the seat is followed by a synchronized adjustment of the backrest with forward tilt; the chair moves to the writing position.
- the piston is in the non-locked zero position on the spring element, and if the weight is concentrated on the rear area of the seat, as is caused when a user leans back, the distance between the two axes of rotation including the first gas spring decreases.
- the piston - from the zero position moves away from the spring element in the direction of insertion, namely opposite to the direction of expulsion - and can move over a distance to an inserted end position.
- the front area of the seat lifts against the tendency of the first gas spring to shoot out from the zero position into a position raised to the floor.
- the movement of the seat is followed by a synchronized adjustment of the backrest with an inclination to the rear; the chair moves into the relax position.
- One axis of rotation is located below the seat and can be moved.
- the base frame is formed by a foot and a seat support. Between the foot and the seat support can be vertical, at least in principle standing spring, preferably a second gas spring, be installed on the Piston rod of the seat carrier is attached.
- the other axis of rotation is fixed and arranged on the seat support.
- Axially through the piston rod of the first A gas spring extends from the outside of a valve rod that can be actuated Valve cone is arranged, to which there is a complementary valve seat in the piston located. When the valve cone is closed, the gas is exchanged between the two Sides of the piston prevented.
- the piston rod passes through an axial one Passage out of the housing of the first gas spring.
- the spring element is fixed within the housing and adjacent to the passage.
- the spring element of the first gas spring is made of rubber or plastic. Alternatively, it is designed as a plate spring or as a pre-compressed gas cushion.
- the spring element in principle has the shape of a piece of pipe on, which surrounds the piston rod led out of the housing. Tabs are on the one hand in a fixed axis of rotation and on the other hand articulated on the seat in a displaceable axis of rotation. The lower Foothills of the backrest are in a fixed axis of rotation on the seat support hinged.
- a spring preferably a coil spring, arranged be that acts parallel to the first gas spring.
- the chair - shown here in the starting position with, in principle, a horizontal seat 3 and an associated, vertically standing backrest 2 - also essentially consists of the underframe, which supports the seat 3 and the backrest 2 .
- the base frame is formed from the star base 4, the vertically rising center pillar 41 and the seat support 10.
- a second gas spring 5 with the upwardly projecting piston rod 50 is installed vertically to vary the seat height.
- the seat support 10 is placed on the free conical end of the piston rod 50 .
- rollers 40 are attached.
- Seat 3 and backrest 2 are usually covered with a cushion.
- the backrest 3 has arms 3 engaging under the seat 3 , the extensions 21 of which are articulated on the seat support 10 in a fixed axis of rotation D1 .
- Claws 22 extend from the arms 20 and are articulated on a displaceable axis of rotation D2 together with lugs 32 extending from the seat 3 .
- the seat 3 can be divided into the front area 30 and the rear area 31 .
- a spring socket 12 is arranged, in which a helical spring 11 is inserted, which is supported against the seat 3 .
- the bearing head 7 is articulated in a fixed axis of rotation D4 with the plunger 70 guided axially therein.
- the piston rod 63 of the first gas spring 6 which on the other hand is articulated in a displaceable axis of rotation D3 under the seat 3 .
- Claws 13 extend downward from the front region 30 of the seat, through which the displaceable axis of rotation D5 extends, to which articulated brackets 14 are articulated on the one hand.
- the link plates 14 are articulated on the seat support 10 in a fixed axis of rotation D6 .
- the actuating and connecting parts form the actuating mechanism 1 of the chair.
- the first gas spring 6 and the coil spring 11 act parallel to one another.
- the backrest 2 is in the basically vertical orientation y 0 and the seat 3 in the basically horizontal orientation x 0 .
- a user sitting in the chair set in this way is in the basically upright basic position.
- the first gas spring 6 is surrounded by a sealed housing 60 which encloses a gas chamber 61 .
- a piston 62 with the piston rod 63 extending therefrom is arranged to be axially displaceable to a limited extent.
- the piston rod 63 extends away from the piston 62 in the expulsion direction, while the diametrical axial direction is defined as the direction of insertion.
- a spring element 68 is arranged in front of the piston 62 in the expulsion direction.
- the piston 62 is in the starting position, in principle with a horizontal seat 3 and a vertical backrest 2, against the spring element 68 in a zero position z 0 .
- This position corresponds to a defined distance between the two axes of rotation D3, D4 including the first gas spring 6 .
- a section of the piston rod 63 is visible between the bearing head 7 and the housing 60 , ie the first gas spring 6 has moved apart.
- a valve rod 64 which can be actuated from the outside extends axially in a valve rod bore 660 through the piston rod 63 of the first gas spring 6, on which a valve cone 67 is arranged, to which a complementary valve seat 66 is located in the piston 62 .
- the piston rod 63 exits the housing 60 of the first gas spring 6 through an axial passage 600 .
- the spring element 68 is fixed within the housing 60 and adjacent to the passage 600 .
- the guided in the bearing head 70 plunger 70 is an extension of the valve stem 64 and acts upon actuation thereto.
- the free outer end of the piston rod 63 is provided with a connection area 65 , from which the end of the valve rod 64 protrudes.
- the first gas spring 6 has a suspension 69 attached to the end of the housing 60 , here in the form of an eyelet.
- the backrest 2 is in a rearward inclined orientation y 1 and the seat 3 is in the forward raised orientation x 1 .
- a user sitting in the chair thus set is in the relaxation position leaning back.
- the distance between the two axes of rotation D3, D4 including the first gas spring 6 has decreased.
- the piston 62 was in the non-locked zero position z 0 on the spring element 68 .
- the piston 62 from the zero position z 0 , has moved away from the spring element 68 in the direction of insertion, namely opposite to the direction of expulsion, and has moved via a path s 1 to an inserted end position z 1 .
- the front area 30 of the seat 3 was raised against the tendency of the first gas spring 6 to drive out from the zero position x 0 into a position x 1 raised to the floor.
- valve rod 64 could be actuated to bring the valve cone 67 into the valve seat 66 , so that the gas exchange between the two sides of the piston 62 via the overflow channel 661 is blocked (see FIG. 2D).
- the backrest 2 is in a forward-inclined orientation y 2 and the seat 3 is in a forward-lowered orientation x 2 .
- a user sitting in the chair set in this way is in the forward-inclined writing position.
- the piston 62 was in the initial position, with the seat 3 in principle horizontal and the backrest 2 vertical , on the spring element 68 in the zero position z 0 .
- the distance between the two axes of rotation D3, D4 including the first gas spring 6 has now increased to a maximum as a result of weight concentration on the front area 30 of the seat 3, as caused when a user bends forward.
- the piston 62 acts against the spring element 68 and moved beyond the zero position z 0 , in the opposite direction to the insertion direction, namely further in the expulsion direction, via a path s 2 until it reaches an advanced end position z 2 .
- the front region 30 of the seat 3 has lowered against the action of the spring element 68 from the zero position x 0 into a negative position x 2 inclined to the floor.
- the movement of the seat 3 was followed by a synchronous adjustment of the backrest 2 with a forward inclination, so that the chair has thereby moved into the writing position .
- a longer section of the piston rod 63 can be seen between the bearing head 7 and the housing 60 , ie the first gas spring 6 has moved apart as far as possible.
