Definitions
- This invention relates to hand and wrist support for keyboard users.
- wrist supports for keyboard users which comprise of an elevated surface attached in front of the keyboard. Resting the wrist on these supports while typing allows some relaxation of neck, shoulder and arm muscles.
- these wrist supports are stationary and do not follow the operator's complex hand movements, thus they offer only an intermittent support, as the user has to repeatedly lift the hands off the support as the hands move across the keys.
- the operator's hands move across the keyboard in a variety of ways.
- Also in the horizontal plane there is a movement of the hands in a bilateral translation motion from one key to an adjacent key to its side.
- a hand and wrist support for typists and keyboard users comprising of an elevated bar on which sliding wrist and hand support surfaces slide on and are capable of following the user's hand and wrist movements.
- Figure 1 - Shows the support in use in its position in front of the keyboard.
- Figure 2 - Shows the front elevation.
- Figure 3 - Shows a cross section of the support.
- the hand and wrist support comprises of an elevated bar 10 on which two sleeves 11 turn around the long axis of the bar and slide along the long axis of the bar in accordance with the movements of the hand and wrist.
- the bar is elevated by means of two lateral legs 12 to allow the sleeves to slide freely without colliding with the table-top surfaces.
- the bar can be of any shape in profile, but preferably its superior surface should be convex to allow for a rocking motion of the wrist in response to flexion extension cycles of that joint during typing.
- a bar with an ellipsoid profile 13 or a round profile can be used.
- the surface of the bar should be of low friction material to allow smooth sliding motion of the sleeves.
- the bar is manufactured in any suitable rigid material, such as plastic, wood or metal.
- the bar may be of a fixed height or have a height adjustment 14 on the two lateral legs, for height control of the support on top of the table, according to the individuals preferences, and type and height of keyboard used.
- the bar can be of any length but preferably of a length which would correspond to the width of most commercial typewriters and keyboards.
- the width or the radius of the bar should provide ample contact area to reduce contact point pressure at the hand and wrist.
- the bar can rest on the table on its two lateral legs 12 or attached to the table top by clamps 15.
- the support can form an integral part of the keyboard, incorporated into the casing of the keyboard during the moulding process, or attached to the keyboard casing by adhesion or screws or clip-on means via the two lateral legs.
- The. sleeves 11 on which the hand and wrist rest are made of flexible materials which are capable of conforming and accommodating to the elliptical shape of the bar as they turn around its long axis.
- Materials such as rubber, low-friction elastic plastics, foamed material or woven material and fabrics can be used for the purpose of the sleeves.
- the sleeves can be of any length or width, and should give sufficient contact area for the wrist to reduce contact-point pressure.
- the diameter of the sleeves is related to the circumference of the bar
- the sleeves are made of one flexible material or a laminate of several flexible materials.
- the first layer 16 which forms the inner radius of the sleeve is made of a low friction material to facilitate sliding on the bar. These can be sheets of flexible plastic or woven fabric materials or any other suitable low-friction material.
- a second 17 cushioning layer can be added to reduce contact-point pressure. This layer can be of flexible foamed porous material, rubber, soft woven fabric materials or any other suitable material. This second layer can be lightly grooved 18 longitudinally to promote flexibility.
- a further laminate can be added as a final cover to the sleeve in the form of fabric material for aesthetic purposes and pleasing texture surface which is in contact with the skin.
- the sleeves can be made of rigid low- friction material covered by a foamed cushioning surface. Furthermore, to improve the sliding motion, the sleeves may sit on low friction washers or ball bearings.
- the bar can be of any shape in profile, channelled or grooved, with rigid sleeves functioning as runners. This would account for side-to-side movement of the sleeve on the bar. Tilting of the sleeve can be achieved by loose-fitting runners sliding on top of a slightly convex surface of the bar, or loose fitting runners with a single longitudinal ridge on the sliding surface over a flat surface bar, or by the adding of a further surface or a rocker mechanism on top of the existing runners.
- the anterior posterior movement of the wrist and hand on the support could be achieved by adding a series of longitudinal rollers or ball bearings, on top of the two runners, or by adding another runner surface which has a transverse anterior/posterior motion on top of the existing runners, or by any other means of runners, rollers or ball bearings.
- the present invention provides a hand and wrist support which is considerably simpler and cheaper to manufacture than any prior art proposals.
Abstract
Support de mains et de poignets destiné à des utilisateurs de clavier et de machine à écrire et servant à soulager un effort musculaire répétitif en suivant et en supportant les bras de façon continue. Le support comprend une barre surélevée (10) s'appuyant sur les bras latéraux (12) et deux manchons coulissants (11) qui se déplacent sur la barre et forment ainsi une surface d'appui mobile pour les mains. On peut régler la hauteur de la totalité du suport au moyen de mécanismes de réglage (14) situés sur les bras latéraux.Hand and wrist support for keyboard and typewriter users and used to relieve repetitive muscular effort by following and supporting the arms continuously. The support comprises a raised bar (10) resting on the lateral arms (12) and two sliding sleeves (11) which move on the bar and thus form a movable support surface for the hands. The height of the entire support can be adjusted by means of adjustment mechanisms (14) located on the lateral arms.
