Abstract
An arm support, comprising an arm supporting element, connected via a connecting device with a lift device, wherein the arm supporting element has a longitudinal direction between a front end and a rear end and is connected via a tilting axis (E) with the connecting device, which tilting axis (E), in top plan view, is situated between the front end and the rear end, wherein the lift device comprises compensation means for bearing the weight of the arm support and a load borne thereon, in particular an arm of a user.
Claims19
An arm support, comprising an arm supporting element, connected via a connecting device with a lift device, wherein the arm supporting element has a longitudinal direction between a front end and a rear end and is connected via a tilting axis (E) with the connecting device, wherein the lift device comprises compensation means for bearing the weight of the arm support and a load borne thereon, in particular an arm of a user,
- wherein the compensation means comprise a parallelogram construction including two parallel arms, and wherein the compensation means further comprise a spring assembly including a draw spring and a cable-pulley system, and
- wherein a first application point of the draw spring is on a first of the two parallel arms, and wherein a second application point of the draw spring is on a second of the two parallel arms, and wherein a force of the draw spring is applied to the second application point via a cable of the cable-pulley system.
An arm support, comprising an arm supporting element, connected via a connecting device with a lift device, wherein the arm supporting element has a longitudinal direction between a front end and a rear end and is connected via a tilting axis (E) with the connecting device, wherein the lift device comprises compensation means for bearing the weight of the arm support and a load borne thereon, in particular an arm of a user,
- wherein the compensation means comprise a parallelogram construction including two parallel arms, and wherein the compensation means further comprise a spring assembly including a draw spring and a cable-pulley system, wherein each of the two parallel arms is formed by a tubular part, which parts contain the draw spring of the spring assembly, and
- wherein a first application point of the draw spring is on a first of the two parallel arms, and wherein a second application point of the draw spring is on a second of the two parallel arms.
An arm support, comprising an arm supporting element, connected via a connecting device with a lift device, wherein the arm supporting element has a longitudinal direction between a front end and a rear end and is connected via a tilting axis (E) with the connecting device, wherein the lift device comprises compensation means for bearing the weight of the arm support and a load borne thereon, in particular an arm of a user,
- wherein the compensation means comprise a parallelogram construction including two parallel arms, and wherein the compensation means further comprise a spring assembly including a draw spring and a cable-pulley system, wherein the compensation means include a screw or the like that is connected to the draw spring which enables one to tune the bias of the draw spring, and
- wherein a first application point of the draw spring is on a first of the two parallel arms, and wherein a second application point of the draw spring is on a second of the two parallel arms.
