FR2864803A1 - Finger accessory for use by experienced typist, has contact support adapted to fingers and taking different shapes with enlarged base, where accessory is fixed to light glove by sticking on reinforced part - Google Patents

Abstract

The accessory (4) has a contact support adapted to fingers and taking different shapes with an enlarged base. The accessory is fixed to a light glove (5) by sticking on a reinforced part (6). The glove is attached at the level of wrist support on a hand-rest of a keyboard. An elastic ring maintains the accessory on the fingers, where the accessory is fixed to the fingers by auto-adherence or separate adhesive.

Description

- 1

  The present invention consists of an ergonomic accessory, adaptable to the fingers, which serves to optimize typing on the keyboard. The innovative principle is primarily the significant reduction of the contact surface with the keys when typing.

  In fact, the use of keyboards, which was reserved for experienced typists, has grown exponentially with the development of computers. The majority of users do not master the typing on the keyboard 10 with a major difficulty for those with big fingers or joint problems at this level.

UTILITIES

  This accessory, a kind of finger-keyboard interface, is generally in the form of a conical stud attached to the appropriate phalanx. The strong reduction of the contact surface with the keys makes typing more precise, avoiding mistakes, and therefore faster. The stiffness of the material makes it more efficient. Its length, limiting the flexion of the fingers, reduces the risk of joint or tendon affections, which are regular for frequent users; also, it may help those who suffer from chronic or acute conditions in the joints of the metacarpus and phalanges.

CHARACTERISTICS

  Given the difference in dexterity and anatomy of users, the search for ergonomics leads to a variety of shapes and sizes, the choice being at their convenience.

  1 / Form: a / the main form is the truncated cone with convex end (1), which adapts to the concavity of the keys; the base is of a certain concavity to fit the phalanx (2). (FIG 1) b / derived forms: various other forms, having the same effect, for example the ogival shape (FIG 2), or with a extended base (3), the shapes: cylindrical (FIG 3), semi-elliptical (FIG 4), ogival (FIG 5), hemispherical - 2 (FIG 6).

  c / adapting to the use of the wheel of a mouse: for joint use of a keyboard and a wheel mouse the accessory attached to the index may have its con-tact surface a little larger , concave, and notched.

  d / positioning: in general, the accessory is fixed orthogonally relative to the finger; However, it may have a certain degree of inclination, at the convenience of the user

(example FIG 7)

  NB: Figures 1 to 7 show the accessory in a section in the sagittal plane.

  e / dimensions: at the convenience of the user; between a few millimeters and about 1 cm in length. 2 / Material: a wide range of materials is suitable, in particular neoprenes and other rubbers, plastics, light metals ... A material which is both rigid and of a certain elasticity is preferable (like neoprene); the realization in an inexpensive material, recycling (light plastics or compacted paper) can make it for single use.

  3 / Embodiment: a / in the complete embodiment, the accessories (4) are fixed at the appropriate phalanges on a light glove, without thumb (5). This glove will preferably be made of lightweight textile, with elastic fibers, and an elastic wrist tightening for better holding. It will have a reinforcement (6) at the level of the attachment (by gluing) of the accessories.

  (FIG 8) b / according to a particular embodiment, this glove may have a lower number of fingers (one to three) c / according to a particular embodiment, this glove can be adorned at the wrist support on the hand rest of a keyboard, a thin plate of synthetic material, anti-stick (PTFE coating or silicone) to facilitate movement on this hand rest (not shown) d / according to a particular mode embodiment, this glove may comprise, instead of this plate, a bead (7) a few centimeters thick, a certain stiffness, anti-adhesive, which can replace the hand rest of a keyboard. (FIG 9) e / according to a particular embodiment, the accessory (4) is held on the finger by an elastic ring (8) on which it is glued; this is particularly suitable for persons hitting with a reduced number of fingers or having a handicap to a finger (FIG. 10) f / according to a particular embodiment, the simplest, the accessory is attached to the finger by self-adhesive or separate adhesive. Made of inexpensive material, it can be single use. The forms of accessory that are most suitable are those with an enlarged base (3) as shown in FIGS. 3 to 6 for better adhesion.
