RU178021U1 - Tube for surface swimming and diving to a depth with a valve to prevent water from entering it based on the magnetic properties of the materials - Google Patents

Abstract

It is known from the practice of using the tube for swimming and diving that the presence of a valve closing the inlet (through which air enters the tube) to prevent water from entering it is a factor in increasing the swimmer's safety. Modern valves are simple in design and convenient to use, but have the disadvantage that they “work” in water and, therefore, are critical to its purity: litter, grass, sand, algae are able to “wedge” the float, as a result of which it will not block the access of water into the tube. This utility model aims to eliminate this drawback, since the closing valve is located inside the tube where there is no water. For this purpose, a scheme of two floats is proposed: the “master” and “slave”, connected with each other magnetic properties (Fig. 1). The “leading” float moves up / down along the cavity closed from above, and water enters it from below, passing through the filter. The float pops up and “drags” the “driven” float behind it, which closes the inlet of the tube (Fig. 2). In addition, the design of the tube and the "leading" float (Fig. 3) provides for the ability to breathe if for some reason the "driven" float "wedges" in the "closed" position.

Description

The utility model relates to devices used in the field of human leisure.

A well-known breathing tube for surface swimming and diving, used, for example, for spearfishing. Critical for the swimmer’s safety is that in the absence of a valve blocking the tube in order to prevent water from entering it, the swimmer’s lungs must have the necessary amount of air to purge the tube after diving, and the presence of such a valve significantly increases safety during diving and spearfishing.

It has several disadvantages associated with the fact that it "works" in the aquatic environment, namely:

During a wave, the valve float is constantly in the “up / down” movement, opening / closing the air in the tube, which creates a certain discomfort for breathing;

The valve float moves through the tube, which in dirty water conditions can lead to jamming;

There is a possibility that between the float and the upper part of the valve there may be trash in the form of a blade of grass, algae, bark, etc., which will not allow the valve to fulfill its function - to block the flow of water into the tube. The technical solution described in this model is aimed at eliminating (reducing) the above disadvantages.

The technical result, in particular in preventing jamming, is achieved both by a structural change in the tube, and by using the magnetic properties of materials, namely:

The tube (1) has an internal partition (10) dividing it into two sections: in the upper part of one of the sections there is an opening (8), which is locked in case of immersion, and the upper part of the second section is “plugged” (9). In both sections there are floats: (4) - driven and (5) - leading from light material, covered with metallized material having magnetic properties, which allow one to pull the other along with the movement of one of the floats.

In the upper part of the partition there is an opening (6) connecting the cavities of both sections and blocked by a float (5) in case of immersion in water.

The float (4) moves up / down along the guide (11) (Fig. 1), the inner surface of which has as little friction as possible with the surface of the float (4).

The upper part of the section with a locking driven float is closed by a filter cap (2) to prevent dirt and litter from entering the tube, but allows breathing air to pass through. By the same purpose, the filter cap (3) (Fig. 2) closes the lower end of the tube section, along which the leading float (5) moves, blocking the hole (6) and the “pulling” float (4) to block the hole (8).

The float (5) has the shape (Fig. 3) of the section of the section necessary to block the hole (6), a good fit with the walls of the section, sufficient for free sliding inside the section. The float has a through hole (7) in case of jamming of the float (4) in the overlapping position of the hole (8).

The work of the utility model is as follows: in the case when the swimmer is on the surface of the water, the float (5) and, accordingly, the float (4) are in the lower position and breathing air enters through the holes (8), (7), (6). When the swimmer begins diving, water through the filter (3) enters the section with the leading float (5) and lifts it to the plug (9), blocking the hole (6), while simultaneously pulling the driven float (4), which, according to the law of magnetic attraction, which in turn, blocks access to water through the hole (8). When diving, water flows out of the section, lowering the float (5), and accordingly the float (4), opening the hole (8). If for some reason the valves are stuck in the lower position, that is, at the time of the dive, the swimmer interrupts the dive and eliminates the malfunction. If during ascent, the valve (4) is stuck in the hole (8) (litter or strong blowing), air enters through the holes (7) and (6).

The tube in FIG. 1 has a ring in cross section, but may have different sections: square, rhombus, rectangle, oval, not violating the functional purpose of the described utility model.
