Definitions

  • the invention relates to a chair, in particular armchair or sofa, with a chassis and a relation to the chassis from a lower non-use position in an upper use position pivotal foot part, wherein the foot part is held on at least one pivotable Tragarm Modell on the chassis, wherein the foot part via at least one pivotable Control fitting is connected to the chassis, wherein the length of the support arm structure between the chassis and the foot part when swinging the foot part from the non-use position to the use position and back, wherein the length of the support arm structure between the chassis and the foot part in the non-use position of the foot part is shorter is as in the position of use of the foot part and wherein the position of the control fitting determines the length of the Tragarm Medical between the chassis and the foot part.
  • chassis On the chassis as a supporting element of the chair usually the individual modules, such as the seat, the backrest and the foot of the chair are mounted. In addition, armrests and / or side parts of the seat can be mounted on the chassis.
  • the chassis itself can stand on the ground via at least one corresponding foot so that all weight forces are dissipated to the ground via the chassis. But it can also be the side parts on the ground, wherein the chassis absorbs the weight forces of the mounted on the chassis and not otherwise supported on the side parts components to derive them via the side parts to the ground.
  • the chassis of the chair can therefore have different shapes and, if necessary, provide a supporting frame or a supporting frame for the seating together with the side panels.
  • the foot part can be pivoted from a lower and rear non-use position to an upper and front use position and back.
  • the user can conveniently deposit his legs or feet on the foot part, preferably with outstretched legs. So that the sitting position is perceived by the user as comfortable, the foot should be positioned in the position of use quite far in front of the seat.
  • the support arm structure for supporting the foot part relative to the chassis must not be too long, so that the foot part in the non-use position can reach far below the seat of the chair and does not affect the sitting comfort for the user in this position. In particular, care should be taken to ensure that the foot does not collide with the ground when pivoting in the non-use position, for example because the Tragarm Quilt Design protrudes far down.
  • the support arm is formed variable in length, in such a way that the support arm extended during pivoting in the position of use of the foot and shortened when swinging down the foot in the non-use position again.
  • the footboard may be connected to the chassis via a separate control fitting.
  • the control fitting is adjusted when adjusting the foot from the non-use position to the use position and back, in particular pivoted, and thus adjusted the foot part.
  • About the control fitting is set in each position of the foot part between the non-use position and the use position, the length of the Tragarm Modell between the chassis and the footboard.
  • the present invention has for its object to design the above-mentioned and previously described in more detail seating in such a way and further that thepsychteilver ein can be provided structurally simpler and adapted.
  • control fitting has a at least two mutually perpendicular axes pivotally mounted on the chassis control lever.
  • the extension and shortening of Tragarm Vietnamese can be tailored to the particular requirements, in part independently of pivoting of the foot from the non-use position to the use position and back.
  • the design of the tillteilver ein can be made more flexible overall.
  • the use of at least two mutually perpendicular axes pivotally mounted on the chassis control lever allows a structurally simpler overall design of predominantlyteilvergna, even if the corresponding storage of the control lever is initially structurally complex.
  • control lever may be directly or indirectly connected to the chassis.
  • required pivotability may be provided by at least two separate joints or joints or by a single joint or joint.
  • Kalottengelenk or ball joint offers a kind of universal joint, Kalottengelenk or ball joint.
  • the latter can also be designed so that the control lever also about an axis is rotatably mounted on the chassis perpendicular to the two aforementioned pivot axes.
  • control lever is also connected to at least two mutually perpendicular axes with the foot part, with a connection between the control lever and the foot providing component or with a connection between the control lever and the foot part providing assembly.
  • this compound can also be provided via a single compound or via at least two separate compounds. From a constructive point of view, however, offers a single connection.
  • the at least one connection can provide a rotatability of the control lever about an axis which is perpendicular to the two mutually perpendicular pivot axes.
  • the degrees of freedom which the at least one connection provides with at least two pivot axes which are perpendicular to one another allow the control lever to be pivoted in at least two separate planes. These levels are perpendicular to each other.
  • the intersection of two planes coincide with the axis about which the control lever is rotatably supported on the chassis or on the adjacent to the other side of the control lever assembly.
  • the support arm structure has a telescoping device. This is used to change the length of the Tragarm Medical between the chassis and the foot in a simple manner.
  • a telescoping device in the form of a rail system.
  • the noise can be kept low.
  • the adjusting forces can be reduced by a corresponding rail system.
  • control lever does not connect the chassis directly to the foot part, although this would be conceivable.
  • a large change in length of the support arm during the adjustment of the foot from the non-use position to the use position can be achieved in principle easier when the control fitting next to the control lever has further components.
  • the control lever is designed as a drive lever of the control impact.
  • About the drive lever namely the adjustment of the control charge is given in total.
  • the control fitting has a drive lever, a coupling lever and a driven lever.
  • Other components are conceivable but less preferred from a constructive point of view.
  • the coupling lever already allows small adjustment movements of the drive lever to be securely transmitted while increasing the adjustment movement.
  • the use of the output lever allows easy transmission of the adjustment of the coupling lever on the footboard. Although it could basically be dispensed with the output lever, but then the coupling lever would not only take over the translation of the adjustment of the drive lever, but also their transfer to the footboard. This would lead to a structurally complex and less flexible design of the tax bill and would therefore generally less preferred.
  • a structurally simple and at the same time comfortable foot part adjustment can be achieved when the coupling lever with one end to the Tragarm Modell and with the the other end is connected to the output lever, wherein the drive lever between the two connected to the Tragarm Modell and the output lever ends engages the coupling lever.
  • the drive lever can push the coupling lever forward or pull it backwards, the coupling lever simultaneously pushing the drive lever forward or pulling it backwards.
  • a suitable choice of the point of attack of the drive lever on the coupling lever while a kind of translation of the adjustment can be specified.
  • a slight adjustment of the drive lever can then result in a significantly more extensive adjustment of the foot part or a significantly more extensive lengthening or shortening of the support arm structure.
  • the drive lever acts on the support arm structure facing half of the coupling lever between the points of engagement of the coupling lever on the Tragarm Jardin and the output lever on the coupling lever.
  • the drive lever it is further preferred for the drive lever to engage the coupling lever adjacent to the end of the coupling lever facing the support arm structure. The greater the achievable translation, whereby the design effort can be reduced.
  • control lever together with the coupling lever, the support arm structure and the chassis form a four-bar chain.
  • This allows a structurally simple design of crizteilver too.
  • the functionality of the foot part adjustment can be reliably provided in this way.
  • the Tragarmregal can be held about a pivot axis relative to the chassis and the control lever above the pivot axis between the chassis and the Tragarm Cook be pivotally fixed to the chassis. In this way it can be ensured that the Tragarm Cook is shortened at downwardly facing foot part, so as not to collide with the ground and / or to be arranged to save space in the non-use position or under the seat of the chair.
  • Another constructive simplification and a stiffening of the scholarteilver ein is achieved when the support arm is connected via a pivot axis with the chassis.
  • the control lever may, if necessary, be fixed indirectly to the chassis. However, it is preferred if the control lever is held directly, in particular via a single pivoting of the control lever about the at least two mutually perpendicular axes enabling connection to the chassis.

  • the said compounds and said pivot axis need not necessarily be arranged exactly in a plane, since the control lever relative to the chassis, if necessary, also opposite the coupling lever, can be pivoted in at least two mutually perpendicular planes, wherein the corresponding pivoting of the control lever in a Level may cause an extension or shortening of the control lever in the other level.
