This device helps the uniform and controlled development of the muscular capacity of the fingers.

Description

Weight-biased exerciser for the fingers
Description Text
This patent application relates to a machine having a system of variable mini-weights which provides calibrated and uniform exercise for the fingers in order to obtain maximum training, control and development of the neuromotory capacity of the fingers.
The device consists of a ring support in which the fingers are alternatively inserted and placed; this support is connected by means of a system of levers or cables to a inert mass whose weight can be modified using removable plates fitted in a prism container sliding on vertical guides.
The machine can be used in the medical-physiotherapeutical field for the motory rehabilitation of the hands in the case of injured limbs, in the sports sector to increase the muscular power of the fingers beyond normal, or by musicians playing various instruments who require strength, ready response and agility in using their fingers and particularly in the case of pianists for whom these characteristics are especially important and where often the instrument alone does not sufficiently develop the necessary strength.
The finger movement can vary according to its ideal articulation; by increasing both the number of the times the exercise is carried out and the effort required to lift the weights added to the container, the required power possible for each person, is achieved.
There are currently almost no known instruments in the technical field and in the field of application to which the invention refers.
The only known instruments are those called "spring pocket handlebars" whose major drawback is that they offer fixed resistance and thereby do not allow an open and wide movement of the fingers separately and stimulate, above all the hold, the grip and t i gh ten ing of the entire hand but do not exercise each finger individually.
To illustrate the characteristics of the invention several versions of the device are described in detail with reference to the enclosed drawings which are intended for purposes of illustration and not in a limiting sense, in which:
- figures 1, 2 and 3 are axonometric illustrations of different construction versions of the device according to the invention;
- figure 4 is an axonometric representation of another version of the invention equipped for exercising two fingers of the same hand at the same time.
The first machine, illustrated in figure 1, includes a ring support for the fingers (1) and is connected - by means of a cable (2) sliding in the races of three pulleys (10, 11 and 12) - to a container (3) whose run is determined by vertical guides (5) on the internal face of the sides (6). This container (3) holds weights (4) made of plates which can be added or removed so as to modify the weight according to the muscular effort required.
The pulleys (10, 11 and 12) are fitted on horizontal pins interposed and resting against the sides (6) on a vertical plane equidistant from the two sides.
These sides (6) are shaped like an upside down "L" with the top horizontal side turned towards the hand support element
(7).
The above muscular effort consists in placing the hand on a hand support surface (7) having groove (7a) so that when the finger pressing on the ring support (1) moves down it lifts the container (3) loaded with weights by means of the cable (2); the cable (2) slides on the pulleys (10, 11 and
15) and pulls them so that they turn; the pulley (11) tightens the cable (2).
The base (8) on which the sides (6) are wedged rigidly, has a hollow section (9) under the container (3) in which a bearing made of spongy material is fitted to act as a shock absorber when the container (3) reaches the bottom of its run. The container drops when the finger is returned from the lowest position to the rest position.
In this rest position, the ring support (1) is at a height which allows the finger of the hand resting on the support (7) to be fitted into the ring easily and conveniently, considering that this finger must be approximately at the same level as the others; this ring (1) is made in a soft flexible material for adapting to different fingers.
The hand support (7) simply rests on the underlying base (3) on which it can be placed in the best position according to the different position of the hand with respect to the support (1) and according to the finger used, as well as to the requirements and somatic characteristics of the user.
The second model of the device illustrated in figure 2 is fitted with a single large pulley (14) instead of the three small pulleys (10, 11 and 12).
In fact the shape of both sides (6) is characterized by a narrow vertical section at the base - having guides (5) on the internal face - ending at the top with a wide polygonal section projecting over the above hand support.
This large pulley (14) is hinged between the above projecting polygonal sections, along whose race at the two points (15a and 15b) two pieces of cable (2a and 2b) are hooked to the ring support (1) and to the weight-holder container (3) respectively.
The principle on which this is based remains the same, with the difference that in this case the cable on which the ring support (1) is hooked no longer pulls the wheel by friction but because it is fixed.
The third model (Figure 3) is fitted with a lever to transfer the ring support (1) movement to the weight-holder container (3).
In this third version of the invention, opposite sides (6) are used having the shape of an upside down "L" whose top horizontal section is turned towards the hand support (7); these sides (6) have two pairs of vertical slots (21) at the two side ends of the respective horizontal sections. The wheels (22) sliding in the pair of front slots, are fitted so that they rotate freely on the external face of two sliding plates (20) joined together by a pin having a horizontal axis (19) while similar wheels (22) slide in the pair of rear slots, fitted so that they rotate freely, on the external sides of the container (3) which is fitted internally with its own transverse pin (19) having a horizontal axis.
The above pins (19) are fitted and slide in two identical longitudinal slots (1B) at the two opposite ends of a lever
(16) hinged at the centre with respect to a horizontal pin
(17) which extends between the two above sides (6).
In particular one of the two ends of the lever (16) penetrates inside the container (3) through a vertical opening made for this purpose on the front face of the same (3).
When the lever (16) oscillates around its fixed pin (17) the container (3), on one side and the sliding plates (20) on the other, make alternating vertical runs guided by their respective wheels (22) coupled with the relevant sliding and guide slots (21), with the pins (19) sliding in the respective slots (18).
In this case the cable (2), by means of which the oscillations of the lever (16) can be operated - ends at the top with two forking parts which permit hooting the same to the pin (19).
The spongy shock absorber bearing in this version is fitted on the shelf (23) where the container (3) lands at the end of its downward runs.
The weights which are placed in the container (3) can be conveniently stored in the compartment (24) between the sides (6).
In all the models the palm of the hand is placed on the support (7) so that the fingers press down thereby exerting the agonist muscles which move the finger when it grips or when it pushes down.
In order to exercise the antagonist muscles, the base (8) is fitted with a slot (8a) in which a pair of adjacent and coplanar pulleys (25) are housed, hinged on respective pins having horizontal axes, and which can be used to transmit the cable (2) by 180° - the same being suitably extended for this purpose - which supports the ring (1) from the top; in this prospective it is understandable that the finger trying to lift the container (3) would not have to push the ring (1) down, but would need to lift it up.
In addition it should be noted that by using any of the above versions of the device, closely fitted multiple devices can be constructed for the simultaneous exercising of several fingers of the same hand; in this case a hand support (7) must be fitted on the base, having the same number of grooves as the machines fitted together.
In particular figure 4 illustrates a model of the device which allows simultaneous exercising of two fingers of the same hand - produced by mounting two devices of the model illustrated in figure 3, side by side.
It should also be noted that, even when using just one device, two or more fingers can be exercised at the same time using supports (1) fitted with two or more rings or with a single larger ring in which the fingers can be inserted at the same time.
To make the use of the machine more precise, a run counter can be fitted on all the devices, to control the number of times the muscular exercise is carried out, and which would otherwise have to be remembered by the user.
In this description several preferred embodiments of the invention have been illustrated, but all possible variations of the invention are intended as being included in the invention.
