Description

The utility model relates to devices powered by a water propulsion device, which make it possible to facilitate the movement of a person in an aquatic environment, and can be used for sports or entertainment in water.

Underwater tugs / scooters are known from the prior art (see, for example, https://ru.wikipedia.org/wiki/%D0%9F%D0%BE%D0%B4%D0%B2%D0%BE%D0%B4 % D0% BD% D1% 8B% D0% B9_% D0% B1% D1% 83% D0% BA% D1% 81% D0% B8% D1% 80% D0% BE% D0% B2% D1% 89% D0 % B8% D0% BA) used for the movement of divers in the aquatic environment. The user must grasp the handles placed on the towing vehicle, after which the towing vehicle turns on and drags the swimmer along. Such towing vehicles have a number of disadvantages, in particular, the jet of water emitted by the propeller hits the swimmer, slowing him down, in addition, this method of movement takes both hands of the swimmer.

There is also known a device for movement in water (see RF patent No. 113160, publ. 02/10/2012), containing a telescopic rod, at one end of which is fixed a gearbox with a pedal drive and at least one screw, and at the other end - a means fastening the device to the human body. The device can be equipped with a means for adjusting buoyancy.

The use of a gearbox with a pedal drive and a propeller as a propeller increases the labor intensity of movement in the water and sets restrictions on the user's physical fitness. In addition, changing the direction of travel while pedaling the gearbox will also require some skill from the user.

The device according to the RF patent No. 113160 is selected as a prototype.

The technical problem to be solved by the present utility model is the creation of a convenient and safe device for movement in water.

The technical result achieved by solving a technical problem is to increase the maneuverability and controllability of navigation, as well as to expand the range of devices for movement in water.

The technical problem is solved, and the technical result is achieved due to the fact that the device for locomotion in water contains a telescopic rod, at one end of which a propeller is fixed, and at the other end - a means for attaching the device to the human body. The propeller is fixed to the bar through a foot stop perpendicular to the bar and rotatable at the point of connection with the bar.

The use of a propeller allows automating the process of movement in the water. The use of a rotary foot stop, to which the propeller is attached, provides simplicity and ease of maneuvering in the aquatic environment, since the efforts of the swimmer applied to turn are minimized. Due to this design of the device for movement in the water, the engine thrust is transmitted to the swimmer's legs, which can significantly reduce the applied forces for movement in the water, and, therefore, increase the convenience and safety of diving.

The mover can be any mover known from the prior art for movement in the aquatic environment and its technical design is not the subject of patenting of this application.

The technical problem is solved, and the technical result is also achieved in the following particular variants of the implementation of the device for movement in water.

The device for locomotion in water can be equipped with a means for adjusting buoyancy. The water mover is made of lightweight and durable materials such as carbon, aluminum, titanium, plastic. Their use in conjunction with an additional means of increasing buoyancy, fixed on the boom, makes it possible to impart neutral buoyancy to the device, compensating for the weight of the propeller, and thus allows it to be used comfortably in the water and provides convenience and safety of use. To vary the degree of compensation for the weight of the propeller, the means for adjusting the buoyancy can be made composite with the ability to change the buoyancy, which, together with the mobility of buoyancy along the bar, allows you to quickly and easily adjust the buoyancy of the device to the needs and skills of the swimmer, which also has a positive effect on the safety of the swimmer.

The telescopic rod of the promenade in water may have a collet lock for adjusting the length of the rod. Thanks to this, a convenient and simple adjustment of the device for a swimmer of any height is provided, it excludes the constraint of the swimmer's movements due to the discrepancy between the device size and the swimmer's height, which in the process of use provides increased convenience and safety.

Connections of the foot stop and the bar, the foot stop and the propeller, the means for attaching the device to the human body and the bar can be made quick-release. The quick disconnect connection can be any known from the prior art and its technical design is not the subject of patenting of this application.

The presence of quick-release couplings provides increased safety for the swimmer, since in the event of a non-standard / dangerous situation, part of the device or the device itself can be easily and quickly unfastened. In addition, quick-release couplings, combined with a collet lock to adjust the length of the rod, minimize the transport dimensions of the device and facilitate assembly.

The device for movement in water is illustrated by drawings. Figure 1 shows a top view of a device for locomotion in water. Figure 2 shows a side view of the device for moving in water. Figures 3 and 4 schematically depict the process of changing the direction of movement of a swimmer with a device in the water.

In accordance with the present utility model, a device for movement in water (see Figs. 1 and 2) includes a telescopic bar (1), in one part of which there is a propeller (2), and in the other part, a means for attaching the device to a human body ( 3), connected to the rod (1) using a quick connector (8). The means for attaching the device to the human body (3) can be made, for example, in the form of a belt. The mover (2) can be any mover known from the prior art for movement in an aquatic environment and its technical design is not the subject of patenting of this application. To compensate for the weight of the propeller (2) and make the device neutral buoyancy, it can be equipped with a means for adjusting buoyancy (6), fixed on the rod (1) with the ability to move along it. The means for adjusting the buoyancy (6) can be made composite with the possibility of changing the buoyancy, which, together with the mobility of buoyancy along the bar, allows you to quickly and easily adjust the buoyancy of the device to the needs and skills of the swimmer. The propeller (2) is fixed to the bar (1) through the foot stop (4), perpendicular to the bar (1). The foot stop (4) is fixed to the rod (1) by means of a quick-disconnect connection (5) and at the same time is designed to rotate at the point of connection with the rod (1). The connection (9) of the propeller (2) and the foot stop (4) is also quick-disconnect. The telescopic rod (1) of the device for movement in water can have a collet lock (7) for length adjustment. Thanks to this, a convenient and simple adjustment of the device for a swimmer of any height is provided, it excludes the constraint of the swimmer's movements due to the discrepancy between the device size and the swimmer's height.

The above described device for locomotion in the water provides simple control of the device along the course (see Figures 3 and 4).

The device for moving in water works as follows.

The user connects the propeller (2) by means of the connection (9) to the foot stop (4), which in turn is connected by means of a swivel quick-disconnect connection (5) to the rod (1). By means of a collet lock (7) and a telescopic rod (1), the required length of the device is selected, which is convenient for the user. The device is then ready for use.

The user, using the means for attaching the device to the human body (3), connects the device to himself. Then the user enters (submerges) into the water (under water) with the device, rests his feet against the foot stop (4), gives a command to start the propulsion device and starts moving. Changing the course occurs by changing the uniformity of pressure with the legs on the foot stop (4) (see Figs. 3 and 4). To turn to the right, the user increases the pressure with his left foot on the support (4), to turn to the left - increases the pressure with his right foot on the support (4). With such actions, the stop (4) together with the propeller (2) rotates relative to the bar (1) and, accordingly, the direction of movement of the swimmer changes. For forward movement, the user evens out the pressure of the legs against the foot stop (4).

During movement, the thrust of the engine is transferred to the swimmer's feet, unlike most famous underwater towing vehicles. With this design of the device, the swimmer's hands are freed, which allows to reduce the load on the user, because he does not have to hold on to the towing vehicle with his hands. Also, due to the release of the hands, the swimmer's freedom of action is provided, which, like reducing the load, provides an increase in convenience and comfort while increasing the safety of use.

The claimed device also expands the range of devices for movement in water.
