Description

DNA handlebar system

Field of technology

The solution concerns the area of handlebars, stems and control elements located in the grip part of bicycles, electric bikes, motorbikes, rickshaws and other vehicles and machines that use handlebars to control them.

Current state of the art

In the first bicycles, which were conceived as scooters and bouncers from the end of the 18th century, the fork of the front wheel and the handlebars formed a single unit, only with further development did the handlebars develop into a separate component. At the very beginning, the handlebars were a straight tube, or rather a wooden log. Later, it began to change its shape to better suit the rider's anatomy. First, there was bending in the horizontal direction, the so-called swallow, which enabled grip in the longitudinal direction of travel. By further curving, the shape of the so-called rams was reached, which enable grip in several planes and angles.

The handlebars themselves, whatever shape they may have, are attached to the fork post of the front wheel by means of the so-called stem, which is a part that defines the distance between the axis of rotation of the front wheel and the grip part of the handlebars. This distance has a major influence on the driving characteristics of the vehicle. The shape and width of the handlebars, the length of the stem and the height of the grip are the basic dimensions of the handlebar part, the settings of which are currently solved by the production scale - the choice of component sizes. As standard, the height of the grip can be changed, which is most often solved using the setting rings on the fork post. Straight handlebars are supplied in the maximum width and can be adjusted to the right size by notching.

Handlebars are supplied with fixed stiffness as standard. Softening of the wheel is most often solved using a suspension fork. However, it is not suitable for road machines, which require the greatest rigidity of the frame and grip parts, therefore they are designed with maximum hardness, which is excellent for energy transfer, but not friendly to health. On an uneven road, for example on pavement, vibrations are transmitted to the skeletal and muscular system, which can damage the rider's health during long-term loads. The cyclist must therefore choose a compromise between comfort and efficiency of his machine.

The essence of the invention

The construction of the DNA handlebar system is based on the principle of parallel shapes, where the grip part of the handlebars is formed by means of parallel bodies, for example cylinders, which are defined in space by transverse segments, for example cylinders, so that they create a stepped ladder structure similar in its arrangement to the molecule of deoxyribonucleic acid, known as DNA. The DNA handlebar system consists of a compact unit of the handlebars and stem, or other elements of the grip part, such as controls for the brakes, gearing system, suspension or other vehicle components, which can be controlled manually. Parallel shapes and transverse segments can change their shape and size by means of an adjustable connection, for example by telescopic adjustment of the cylindrical bodies, which enables precise adjustment of the individual dimensions of the grip. The telescopic connection of parallel shapes and transverse segments enables the grip part to move in a certain stroke - the handlebars can spring.

The adjustable device can change the properties of the DNA handlebar system, for example the stiffness of the grip surface, or other properties such as the height of the grip, its shape, roughness, temperature, air vent, or other quantities, either mechanically, pneumatically, hydraulically, electromagnetically, or in another way, or their combination. This can be done, for example, with the help of a lever on the lower frame tube of the bicycle, which controls the cable that acts on the adjustable device.

The skeleton of parallel shapes and transverse segments can be additionally softened by another layer of material, either solid, liquid or gaseous, for example as foam padding, gel capsules or

A compact part of the DNA handlebar system can be rotating handles in the shape of the letter "O", which can be used to control other elements of the vehicle, such as brakes, transmission system or other components. The circular handles can be rotated without fear of deformation at different angles, which makes it possible to control several elements of the machine at once. By turning the circle, you can shift, for example, by squeezing - deformation of the wheel, and braking.

Examples of implementation of the invention

The DNA handlebar system is formed by a circle of parallel bodies 1, which is defined by transverse segments 2. The entire DNA handlebar system is attached to the column 3 of the front wheel fork. By telescopic adjustment of 4 parallel bodies 1 and transverse segments 2, the shape and dimensions of the gripping surface or its individual parts can be changed. A compact part of the DNA handlebar system can be rotating handles 5 in the shape of the letter "O", which are used to control other elements of the machine, for example brakes or transmission system. By turning 6, for example, the gears can be controlled, and by squeezing, deforming the circle 7, you can brake, the circular segment can also be deformed or rotated in the axial direction 8. The properties of the handlebar system can be changed, for example, with the lever 9 on the lower tube 10 of the wheel frame. The lever 9 pulls the steel cable 11, which passes through the circuit of the parallel bodies 1, by tightening or loosening it, the stiffness of the gripping surface changes. The DNA handlebar system can be additionally softened with an air cushion of the grip surface 12, which can be inflated with a valve 13.

Industrial applicability

The DNA handlebar system with variable geometry and grip stiffness is suitable for all types of bicycles, e-bikes, motorbikes, scooters and other vehicles and machines that use handlebars. Sports riders on long routes will appreciate them the most, as they allow setting of all grip parameters with millimeter precision. The ability to change the stiffness will especially relieve the back muscles during long-lasting performance.
