WRITING AND DRAWING ARRANGEMENT

Abstract: The invention relates to a writing and drawing arrangement, referred to as a finger pen (2, 3, 4). We have clung to the traditional notion that pens or pencils must be rod-shaped in spite of the fact that this subjects the fine-motor function of the user to unnecessarily stringent demands. A study of the development of the fine-motor function of children proves that a semi-supine grip on rod-shaped pens or pencils can normally not be achieved out before the age of 6-7 years. The invention solves this problem by means of a finger pen (2, 3, 4), prone holding (1) of which is already possible at an age of 2-3 years, which generally makes possible its use in a manner which as regards the fine-motor function is simplified. Pen nib (5) projects from or in the vicinity of sensible centre of feeling (7) of writing/drawing finger (6) and is so angled that the point at which it contacts the writing/drawing surface will be seen by the user. Various alternatives of finger pen (2, 3, 4) are possible, e.g. of open type (2), closed type (3) or contoured shape (4). The invention applies mainly to writing/drawing while holding the pen in a prone position (1).

Description: WRITING AND DRAWING ARRANGEMENT The invention relates to an arrangement in accordance with the preamble of claim 1. Definitions of the concepts relating to positions of the hand etc. as used below: - supine position of the hand - palm of the hand turned upwards - semi-supine position of the hand - palm of the hand turned to the side - prone position of the hand - palm of the hand turned downward - sensible centre of feeling - the point on the writing/drawing finger which, when gripping very small objects against the thumb, balances the object in a controlled position. It is well known that writing and drawing arrangements, referred to below as pens, have traditionally been designed as rods containing graphite, ink, paste and similar substances, whereby the tip produces the stroke of the pen when the latter is applied to a surface. The rod shape was the same with the predecessors of modern pens such as brushes, gas pens, steel pens etc. When rod-shaped pens started to be manufactured, the industry had, at that time, insufficient possibilities, both technologically and in terms of material, of using other types of pen. However, there is no doubt, that today' ε state of the art enables a new approach aiming at a more efficient design. We have unfortunately clung to the traditional notion that pens must be rod-shaped, in spite of the fact that this makes unnecessarily stringent demands on the fine-motor function of the user. We understand the problem most readily by studying the fine-motor development of a child, which proves it to be so complicated to hold a traditional pen that the brain of a child is, as regards the fine- motor function, normally not sufficiently developed for so-called semi-supine holding of the pen or pencil until it is 6-7 years of age. The object of the invention is to solve the above problem in such a way that using modern technology and materials we have an alternative to the traditional design of pens, suitable for holding the pen in a manner subjecting the user to less stringent fine-motor demands, i. e. a manner of holding the pen which can be achieved at an earlier stage of our fine-motor development. The invention, referred to below as a finger pen, presupposes holding the pen by a prone grip, which a human being with normal fine-motor development can achieve already at the age of 2-3 years. Hence the invention favours - generally simplified holding of the pen - the possibility of children handling a pen in a functionally correct manner at an earlier age - easier learning of writing and drawing by schoolchildren - a greater possibility for adults with inadequate fine- motor function to control their pens. A secondary advantage of the finger pen consists in the fact that one obtains a much better view of one* s writing, which is especially true in the case of left-handed people. Prone holding of the finger pen works best if its pen tip projects from or in the vicinity of the sensible centre of feeling of the writing/drawing finger and faces away from the latter, at such an angle that the pen tip is visible to the eye of the user, down to the surface at which the stroke of the finger pen is to be produced. Moreover, the solution constituted by the finger pen is apparent from the characterising part of claim 1. An embodiment of the invention is shown in the attached drawings, where Figs. 1 and 8 are illustrations of three different writing/drawing arrangements, referred to below as finger pens, in which the pen is held in prone manner, 1, with Figs. 2, 3 and 6 showing a finger pen of open type, Figs. 4, 5 and 7 a finger pen of closed type, Figs. 9 and 10 a finger pen of contoured shape, and Fig. 11 a guard or the pen tip. In general the following applies to the different finger pens 2, 3 and 4 of the embodiment: The extension of pen tip 5 towards the user' s finger 6 emanates from or in the vicinity of the sensible centre of feeling 7 of finger 6 and is angled roughly as shown in the attached drawings, i. e. it is angled in a way which by and large corresponds with the normal pen angle when using a traditional pen holding the pen in a semi-supine manner. As a result, the point at which tip 5 of the writing implement contacts the writing/drawing surface 8 will be visible to the user. If finger pens 2, 3 and 4 are not in use, a guard 9 is placed over tip 5 of the pen. The different inger pens 2, 3 and 4 comprise a container 10 with paste, ink etc. , directly connected with tip 5 of the pen, its size being maximised irrespective of whether finger pens 2, 3 and 4 are designed with or without support grip 11. Specifically the following applies to the different finger pens 2, 3 and 4 of the embodiment: The Figures on page 7 show a finger pen 2 of open type 12 and a finger pen 3 of closed type, so designed that inner surface 13 abuts, in ergonomically correct manner, the user' ε finger 6 and is retained there by means of the pressure and friction between inner surface 13 and the user' ε finger 6 brought about by the characteristics of the material and the design of finger pen 2 and 3, the closed finger pen 3 being possibly complemented with a clip, buckle etc. 14. Finger pen 2 and 3 can be complemented with a support grip 11 (.page 8 and can in that case be so designed as to be retained in the manner described above, or with the aid of support grip 11, whereby the above method of retention can be dispensed with. Figures 8, 9 and 10 show a finger pen 4 of contoured shape, in which contact face 15 is made to fit the lower part of the user' s finger 6. The extension of contact surface 15 constitutes a support grip 11 resting against the user's finger 6, by means of which the user retains finger pen 4.
