Technical field

The technical solution refers to a device facilitating sliding movement intended for sports equipment such as skis - skialp skis, cross-country skis, sledges, etc.

The current state of technology

Currently, there are several variants of technical aids that help recreational sportsmen & women overcome various terrain obstacles, slopes and distances while engaging in sport activities.

Several improvements and modifications of sporting goods are described in patent literature. As an example, we provide patents GB no. 2568652 A - A motorized sled and GB no. 2499048 A - A steering and speed control sled. Next, we would like to mention patent: SK UV 8118 - A racing sled with sled addition, which has a riser on the back structure of the sled that bridges the left and right sled. Patents SK UV 8337 and SK UV 8458 deal with the adjustment of the front and rear part of the ski binding in order to minimize weight and simplify the use of skis in walking mode.

The objective of these technological aids is to help overcome terrain obstacles, climbs and distances with less physical effort. It is based on a regulated force that is transmitted to the drive unit. The most widespread method of such a technical aid is its use on bicycles of various designs, where the turning force is transferred from the auxiliary electric motor to the bicycle's drive wheel and thus helps recreational sportsmen/women.

In principle, they do not need to use as much energy to drive the bike through the pedals that drive the wheel.

There are two ways of using it to facilitate the torque, either by the auxiliary drive to the rear wheel or by the auxiliary drive in the pedal part of the bicycle.

This principle can basically be used in many cases where the basic movement of the given device is based on a wheel.

This method of reducing the physical demands on an individual is not suitable and feasible for moving in a straight line, i.e. in a linear manner.

Currently, a belt is also used, as an integral part of various machines and devices. They are used in the military industry for cars and tanks, as well as in the construction industry for heavy equipment for the preparation of hard-to-reach terrains, but also in the winter season for the preparation of slopes for winter sports, specifically for snowmobiles.

The advantage of the belt is a much larger friction surface than with wheels, which tend to sink on soft surfaces. The basis of the solution was the combination of both advantages, i.e. overcoming various terrain obstacles, climbs and distances by connecting the motor, battery and belt for straight-line movement.

The identified deficiency can be overcome by the implementation of the device described in this solution.

The summary of the invention

The device consists of an electric motor that is attached to the base using a quickrelease mechanism, a replaceable rechargeable battery that is connected to the electric motor, a movable replaceable belt that slides into the motor through the axles of the wheels and a base that is attached to individual elements of use, while the device contains a height adjustment mechanism for belt pressure, a display, speed control buttons, electric motor power control buttons, a latch for locking the movable replaceable belt, a latch for locking the base, a latch for locking the replaceable battery, device start/stop buttons and a charging port with adapter.

The overview of the figures on the technical drawings

The technical solution is explained in more detail with the help of figures 1 to 4.

Fig. 1 shows a view of the complete apparatus for facilitating sliding movement. Fig. 2 shows the individual main parts of the device. Fig. 3 shows the possibilities of using the device for individual sport equipment. Fig. 4 shows the possibility of replacing the belt with wheels or gears.

Examples of implementation of the invention

The device consists of 4 main parts, namely the electric motor (1), the replaceable rechargeable battery (2), the movable replaceable belt (3) and the base (4), which is used to reduce physical demands. The charged battery (2) is connected to the electric motor (1) with the help of a lockable latch (13). The movable replaceable belt (3) also slides into the electric motor(1) through the axles of the wheels, which are an integral part of the belt, with the help of another lockable latch (11).

The components connected this way form a whole, which is simply attached to the base (4) by means of a lockable latch (12), using a quick-release mechanism, which is attached to the individual elements of use (16), and the device is put into the „on mode' ¹ using the start/stop button (14). For better friction of the belt (3) with the surface, the belt (3) is pressed against the surface using the mechanism (5), and thus the device is ready for use. As soon as we set the individual elements of use (16) in motion with our own physical strength, we spin the belt (3) pressed against the surface, and thus the driving force is transferred to the electric motor (1), which, according to the setting with the buttons (7, 8) for regulating the speed and the buttons (9, 10) for regulating the power of the electric motor, helps to ease the physical load of the individual and thus helps to overcome various terrain obstacles, climbs and distances. The advantage of the device is also its different possibility of attaching to individual elements and the possibility of connecting to a smart application.

Industrial applicability

The device for facilitating sliding movement according to this solution can be used for sports activities such as skialp skiing, cross-country skiing, or also for sledding, pushing strollers, etc.
