Abstract

Handle has a cylindrical shape with a larger cross-section 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 tapers at the handle ends, the handle diameter anatomically copying the palm shape. The handle is made of rubber or silicone.

Description

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

Prior art

Bicycle and motorcycle handles are manufactured all over the world, which use their longitudinal inner holes to copy different steering wheel diameters. 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 hitherto used narrow straight handles, resp. handles with fine arch:

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

- the natural arches of the metacarpal, less carpal bones are deconfigured; soft structures stretch: blood vessels, nerves, tendons of the hand, located in the natural palm and wrist depression;

- the hard, unformed handle of the steering wheel presses the palm space with its current small contact surface in one line: the blood vessels, nerves, tendons, etc., 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 base area 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 these areas 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 his 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, hand.

For these reasons, the cyclist releases his fingers from a fixed flexion position, often letting them "hang" freely on the steering wheel, relying with even greater pressure on the described two points of contact of the distal finger arch. If the cyclist releases the pain in his hands and fingers as he releases 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 cyclists' typical difficulties. carpal tunnel syndrome. The handles used in the world are mostly hard, narrow, cylindrical on a flat surface, some with a fine arcuate 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, respectively. also with palm pads, which take into account the anatomical configuration and physiological resting position of the fingers, while these 12 - 15 cm handles for adults are gradually symmetrically at both ends, some slightly asymmetrically extending towards the center of the handle. From the outer side of the handle with a circumference of about 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 inner side of the handle to a circumference of about 12 cm, as palm-finger the index finger is obviously larger than the detto little finger arc. In the case of handles for women and children, the dimensions are reduced proportionally. The handles with the stated shape and volume direct the fingers as much as possible to the resting position of the hands, in which the hands, their fingers rest. The handles fill the palm space of the hands with their volume. 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 in their middle section towards the inside of the handle, due to a significant difference in curvature of the index finger and III. finger. The shape and volume of the handle is aimed at achieving a calm position of the hands.

Examples of embodiments

When selecting universal handle sizes, the dimensions of currently manufactured brake-to-lever 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 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 in their natural resting position during physical activity, 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, with the handle diameter anatomically palm of hand. The handle is made of rubber or silicone.

An alternative solution for creating MEDI-TOR grips is the use of molded self-adhesive MEDL-TOR palm pads, which customers will be able to stick in the middle of the already mounted narrow cylindrical handles of their bicycles, motorcycles, respectively. for longitudinal work tools such as shovels, rakes, pickaxes, etc., MEDI-TOR palm pads 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 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 MEDI-TOR shaped pads will match the shaping of the MEDI-TOR handles.
