Description

" WIDE USE SCISSORS "

The present invention relates to a polyvalent scissors that can be used by persons with varying degrees of deficiency. It is known that patients with any type of deficiency that affect the movements, especially the movements of the hands, have great difficulty if not impossible, to handle utensils for which it is necessary to have a certain muscular and articulate dexterity that allows him to carry out the necessary movements in a coordinated way to the use of certain utensils. Such is the case of articular patients or other permanent deficient persons who experience great difficulties in handling scissors and other similar tools. In addition to the above-mentioned patients, the elderly are particularly affected, which sometimes show more or less significant functional reductions.

The scissors have numerous applications in the arts and industry, taking the shapes and sizes most convenient to the nature of the materials to be cut and also the effort required for their use, while retaining their fundamental design.

In fact, scissors, ordinary utensils, by their design, are usually very difficult to handle by people with some degree of disability. The traditional design and until now known have the axis defined by the blades and their point of articulation forming a shallow angle with the axis defined by the deities, that is, the deities are in the extension of the blades. This implies a difficult use since they do not allow the support of the hand in appropriate handles but only of some of the fingers, requiring on the other hand a position of the hand at an angle with the scissors which is not easy to reach in the elderly or disabled people. -2-

With this new design of a pair of scissors it has been sought to avoid the drawbacks previously mentioned in order to allow the use of this type of utensils by persons who normally would not be able to because of some degree of deficiency or old age.

To solve the main drawback of the known scissors an implement has been conceived in which the angle formed by the axis defined by the blades with their point of articulation with the axis defined by a tangent internal to the handles is 90 ° ± 7 °, i.e. , the blades are substantially in a plane perpendicular to the handles. Such a design allows firstly to support the hand on a surface, to use all the hand in the handles and fundamentally to realize a movement of much easier execution mainly for people with some degree of deficiency.

For ease of understanding the following description is attached a sheet of drawings in which a preferred embodiment of the model to be protected without any limiting character has been represented. In the drawing: Figure 1 shows the scissors, object of the model, with a main elevational view; Figure 2 shows the same object with a rear elevational view; and Figure 3 further shows the same scissors also in the main elevation but with the blades in the open position.

As can be seen the scissors are constituted by the blades 1 and 2 which act in a rotary movement about the axis 3, by the handles 4 and 5 which are in the extension of the blades but making with them a sharp angle of ± 90 °, the spring (6) ensuring the return of the blades in the open position, and the brake (7) which, when actuated, allows the blades to be kept in the closed position.

As a fundamental and innovative characteristic this new design of a pair of scissors presents the axis defined by the blades (1) and (2) and its pivot point (3) forming an angle of 90 ± 7 ° with the axis defined by the inner tangent to the handles (4) and (5) which lie in the extension of said blades.

As previously mentioned this model of execution should not be understood as limiting but on the contrary possible various changes, in particular in the geometric form that derives from the applications for which scissors is intended. Thus it is possible to conceive, on the same principle, pruning shears, tailors or any other specific purpose.

In summary, as a result of this new design for scissors, the main advantages are: a) to allow the use by patients, elderly or disabled; b) can be used with advantages in various positions even by normal people, namely in the inverted position, ie with the blades facing upwards; (c) it is possible to apply its design to any type of scissors with or without specific purposes. The model should only be considered limited by the spirit of the following claims.

Claims (3)

A scissors having two blades which act in a pivotal movement about a pivot axis and two handles lying in the blade extension, characterized in that it has the axis defined by the blades and their pivot point forming an angle of 90 ± 7 ° with the axis defined by the inner tangent to the handles that are in the extension of said blades. A scissors according to the preceding claim, characterized in that each of the blades and handles in the appropriate configuration is disposed according to the specific purpose for which it is intended, one of said handles having a hand guard while the other handle is smooth . Scissor according to the preceding claims, characterized in that it has a spring which acts between the upper part of said blades in order to guarantee the position of the blades open while the position of the blades is closed by a suitable brake.
