Definitions

  • the invention concerns a support on which the forearm of a person operating a computer, a typewriter or performing other desktop operations, may rest during the work.
  • Devices for this purpose consisting of a first pivotal arm section which is secured to a table-top mounted holder and which is arranged for pivotal movement about a vertical shaft.
  • a second pivotal arm section which is mounted on the first pivotal arm section, is arranged for pivotal movement in a horizontal plane about the outer end of the first pivotal arm section and is provided with a support element on which rests the forearm of a person working at the table-top.
  • a forearm support of this kind With the aid of a forearm support of this kind, one on either side, persons working e.g. with computer terminals, may avoid that certain groups of muscles are exposed to unbalanced load with resulting musculo-skeletal disorders, an affliction of which hitherto a large number of individuals have been the victims.
  • the various types of supports available on the market comprise a pivotal arm section consisting of two parallel arms. In order to set the support proper at the vertical position which corresponds to the correct and appropriate working position for the individual user, the pivotal arm section is adjustable with the aid of one or a couple of set screws.
  • the number of possible positioning variations vertically are comparatively limited, which is often rather unsatisfactory, particularly when, as often is the case with computers, the keyboard is positioned in a lower-level recess formed in the supporting table-top o when the keyboard is positioned on an extension table top.
  • Fig. 1 is a perspective view of the forearm support in use, and Fig. 2 shows the support in a lateral view in a certain vertical position with another, alternative vertical position being indicated in dash-and-dot lines.
  • a support holder 2 is mounted on a table top 1.
  • the support holder 2 comprises a C-clamp of a structure generally known per se and comprising two legs 3 and 4 which are joined together by a screw 5.
  • An extra through hole 6 makes it possible to obtain a position of adjustment with a wider spacing between the legs 3, 4.
  • a tightening screw 7 in threaded engagement with the clamp leg 4 secures the holder 2 to the table top 1.
  • first pivotal arm section 8 in accordance with the invention for pivotal movement about a vertical shaft 9.
  • the pivotal arm section 8 is formed with housings 10, 11, one at each end of the pivotal arm 12 proper.
  • the pivotal arm 12 is mounted in said housings 10, 11 so as to be pivoted and lockable therein in any desired angular position by means of a cone member 13 (only one of which is illustrated) and a tightening screw 14.
  • the pivotal arm 12 comprises two mutually parallel end portions 15, 16 and an intermediate portion 17 extending obliquely between the two end portions 15, 16. Owing to this configuration, it becomes possible, when the end portions 15, 16 are turned in their respective bearing housing 10, 11, to raise or lower the outer extremity portion to the desired vertical level between the maximum highest and the maximum lowest positions.
  • a further housing 18 In the latter is received one end of a second pivotal arm section 19 which is arranged for pivotal movement to the desired angular position relatively to the first pivotal arm section 8 and which is provided on its outer end with a forearm support element 20 arranged for turning movement.
  • the support element preferably has a dish-shaped configuration in order to provide some support also laterally during pivotal movements.
  • a person who is operating a keyboard may relieve the load on his neck and shoulder muscles in a very efficient manner.
  • the screw 14 is unscrewed, thus untightening of the cone 13 somewhat.
  • the same procedure is used as regards the housing 10.
  • the pivotal arm 12 is then turned in one or the other direction in such a manner that the pivotal arm section 19 together with the forearm support element 20 are raised o lowered, according to wish.
  • the end portions 15, 16 are again locked in position in their respective one of housings 10, 11.
  • the device in accordance with the invention is easy to handle due to its simple and uncomplicated structure and it may be manufactured at comparatively low costs.
  • the design of the device is, however, not limited to that illustrated in the drawings but may be varied in many ways within the scope of the appended claims.

Abstract

Ledit support pour l'avant-bras est destiné au travail effectué par exemple sur un bureau, et comporte une première partie de bras à pivotement (8) fixée sur un support (2) monté sur le dessus de table (1), ainsi qu'une deuxième partie de bras à pivotement (19) qui est reliée à la première partie de bras à pivotement (8) et est équipé d'un élément de support de l'avant-bras (20). Les deux parties de bras à pivotement (8, 19) sont disposées pour réaliser des mouvements de pivotement par rapport au support (2). La première partie de bras à pivotement (8) comprend un bras (12) muni de deux parties extrêmes parallèles l'une à l'autre (15, 16) et une partie de bras intermédiaire qui s'étend de manière oblique (17), reliant les deux parties extrêmes. Les deux parties (15, 16) sont montées de manière à pouvoir tourner et à être fixées et bloquées dans la position angulaire souhaitée, chacune dans son boîtier respectif (10, 11) qui sert d'articulation de pivotement.
