Abstract

The handle has a cylindrical shape with a larger cross-section in the middle, which forms a central cushion with a slight continuous surface elevation on both sides towards the center of the handle length and tapers at the ends of the handle, the handle diameter anatomically copying the palm shape. The handle is made of rubber or silicone.

Technical field

The subject of the utility model is a larger and also differently shaped handle for bicycles, motorcycles, and work tools, which corresponds to the anatomical and physiological properties of a human hand.

Prior art

Handles for bicycles and motorcycles are manufactured all over the world, which copy the different diameters of steering wheels with their longitudinal inner holes. The thickness of the handles themselves is usually only a few mm. The shape of the handles is a straight cylinder, resp. with a fully fine convex curvature, slightly thicker than the outer circumference of the steering wheels. Some bicycle handles are extended by a protrusion on the outside of the handlebars, they serve as armrests in the area of their hypotenar. Consequences of the use of previously used narrow, straight handles, resp. handle with fine arch:

(a) when resting my hands on the steering wheel, the weight of the upper body:

- the natural arches of the metacarpal bones are deconfigured.

Soft structures stretch: blood vessels, nerves, tendons of the hand, located in the natural palm and wrist depression.

- the hard non-molded handle of the steering wheel presses with its actual, small contact surface in one line on the palm space: on the vessels, nerves, tendons, ... etc ’., it compresses them. These structures are exposed to even greater pressure, their vulnerability, as a result of the described flattening of the bone arches that naturally protect these structures. The contact surface of the hand and the handle is reduced to the two front ends of the bone arches of the palm, to the palm part of the head II. of the metacarpal bone and its joint and to the area of the base of the V. of the metacarpal bone and its surroundings. These congestion points have long been identified, with bicycle glove manufacturers sewing cushions mainly in the areas mentioned in order to soften the contact surfaces.

b) the outer circumference of the handles produced so far is small, unformed.

With a full grip, the cyclist is able to press the currently manufactured handles firmly and keep them with the force of pressure in his hands without difficulty only for a short time.

For the hand, its fingers, the almost full grip of the fingers, as well as their full extension, is unnatural for a long time.

In this "violent" position of the fingers, the cyclist's hand cannot relax, it is exhausting for the fingers, the hand.

For these reasons, the cyclist releases his fingers from a fixed injection position, often letting them "hang" freely on the steering wheel, relying with even greater pressure on the two contact points of the distal finger arch described above. If the cyclist relieves the pain of his hands and fingers when releasing his fingers on the steering wheel, he releases the pressure at the two palm contact points and transfers the weight to the palm base area, to the hypotenar, less to the front of the wrist, again leading to typical cyclist difficulties. carpal tunnel syndrome. The handles used so far in the world are mostly hard, narrow, cylindrical on the flat surface, some with a fine curved ridge on the outer surface of the handles. These handles distort the natural configuration of the hands, exhausting them, causing difficulties for cyclists.

The essence of the technical solution

These shortcomings are solved by a technical solution, which is a special anatomically shaped, bulkier handles or. also with palm pads, which take into account the anatomical configuration and physiological calm position of the fingers, these 12 - 15 cm handles for adults gradually, symmetrically, at both ends widen towards the center of the handle. From the outside of the handle with a circumference of approx. 11-12 cm, it widens towards the center of the handle to a circumference of standard 15 - 17.5 cm (19 - 20 cm) and then narrows on the inside of the handle to a circumference of approx. 12 cm, as the palm-finger arch of the index finger is obviously larger than the detto arch of the little finger. In the case of handles for women and children, the dimensions are reduced proportionally. The handles with the stated shape and volume point the fingers as far as possible towards the rest position of the hands, in which they can guide their fingers to rest. The volume of the handles fills the palm space of the hands. The contact surface of the hands and specially shaped handles according to the technical solution will increase significantly during their normal use. The transferred body weight is distributed more evenly on the palm side of the fingers and on the palm surface. These handles minimize deformation of the wrist, metacarpal bone arches, while the handles according to the technical solution may also have a slight asymmetry of curvature of these handles at their middle section, towards the inside of the handle due to a significant difference in curvature of the index finger and III. hand finger. The shape and volume of the handle is aimed at achieving a calm position of the hands.

Examples of embodiments

When choosing the universal dimensions of the handles, the dimensions of the currently produced brake gear levers must be accepted. The thickness of the handles must be chosen with sufficient free space between the handle and the said levers. In the case of 15 cm handles, the narrowing - thinning of the handles away from the center of the steering wheel creates enough space for the necessary manipulation of the fingers with the levers. The specially shaped handle is used to bring the hands of cyclists, motorcyclists, or other users as much as possible into their natural rest position during physical activities such as sports or work. It is a flat-shaped handle, where the handle is characterized by its cylindrical or ellipsoidal shape with a larger diameter in the center, which forms a central cushion with a slight continuous surface elevation on both sides towards the center of the handle length and narrowing of various dimensions at the handle ends, anatomically hand palm shape. The handle is made of rubber or silicone.

An alternative solution for creating MEDI-TOR grips is the use of molded self-adhesive MEDITOR palm pads, which customers will be able to stick on the center of already mounted narrow cylindrical handles of their bicycles, motorcycles, respectively. for longitudinal work tools, such as shovels, rakes, pickaxes, ..., etc., MEDI-TOR with palm cushions, cyclists will be able to increase the volume of their existing handles. They will be fixed with their entire self-adhesive surface and, if necessary, the MEDI-TOR cushions will be further reinforced with tape on the original handles. They should be: 1 - 2.5 cm high, 8 - 9 cm wide, 8 - 12 cm long, they can be adjusted by cutting. The pads may gradually thin (in the transverse direction of the handles) and overlap each other in the line of their connection.

The final shaping of the classic cylindrical handles after loading the shaped MEDI-TOR cushions will coincide with the shaping of the MEDI-TOR handles.
