The invention relates to devices for catching fish, and can also be used to catch other aquatic organisms.

There are various designs of bottom lifting traps for catching fish, crabs and etc. containing canvas frame of articulated United rods, as well as a system for sling landing cloth and/or lifting traps [US patent 1403171, publ 10.01.1922; US patent 2728164, publ 27.12.1955; US patent 4406083, publ. 27.09.1983; A.S. SU 1514296, publ 15.10.1989: US patent 4956935, publ. 18.09.1990; US patent 6247264, publ 19.01.2001; patent RU 2189140, .20.09.2002]. Known traps have a relatively low reliability.

As a prototype selected trap for fish, containing canvas planted on sling, the framework of the United arm cores, the external ends of which have to skip sling in the form of loops, and lifting straps [patent RU №2063133, publ. 10.07.1996]. The lower ends of the lifting straps connected to the hinges, and top stitched together or with lifting rope. Rods frame connected with a hinge through embedded in it elements, with the necessary firmness. The speed of information loops traps when its rise is relatively low, and used sling system does not allow to securely hold loops rods closed up, so part of the fish can "get away" with the rise of such traps.

Solved the technical problem is the increase of reliability and ease of use traps.

Four types of traps

On the first and second options, as its prototype trap contains canvas, skeleton from bars, which articulated joints their neighbors ends with a Central hinge means, as well as sling system for landing paintings and lifting traps, including slings fastened to the top ends in the bond and United with external ends of the rods.

New under the first option is that that system sling additionally includes the Central sling, the lower end of which is fixed on the Central articulating vehicle, and at the upper end of which is fixed a guiding Bush with a through hole or crossing holes, slings skipped the opportunity slip through the hole or holes in the guide sleeve its branches located from the place of fastening to the point of connection with the external ends of the rods. Through the use of guide sleeve enables faster bringing together outer ends of rods, i.e. faster "slamming" such lifting traps, and provide a more reliable retention of the external ends of the rods near each other when lifting traps, due to which the caught fish is more firmly held inside Polota.

Better when the length of the Central sling is made not less than the length of the rods.

In case of use of traps with multiple cores, and accordingly slings, the number of crossing holes in the guide sleeve better perform equal to the number of missed through her sling that will reduce the likelihood of tangling sling.

Swivel neighbors ends of rods with the Central articulated vehicle may be performed elastic.

Trap may include vertical canvas planted on the branches of the sling, located between the place of their composition and the place of connection with the external ends of the rods, but also at the bars, the ends of which are connected to the mentioned lines. Thus, the trap is used as a small vertical benthic network. The vertical cloth can be planted at the bars with additional lines, each of which is joined with the ends of between internal and external ends of the corresponding rod. Additional lines can be attached one end to the external end of the rod and the other end to a Central articulated vehicles.

Central pivot tool can be in the form of the Central sinkers with the hinge elements on the number of cores. The rods near the outer ends and/or neighbors ends can be supplied with peripheral sinkers, total weight of which is less than the mass of the Central sinkers.

Trap can contain three or more cores. The system sling may include lines connecting consistently outer ends of the rods, and less rods planted canvas. Also slings, bonded upper ends in the bond can be connected to external ends of the rods so that passed through the ears, made at the outer ends of the rods, with possibility of sliding in her ears, and fixed bottom ends consistently at the ends of the neighboring rods, and the resulting branch of the lines between the external ends of the rods planted canvas. The ears may be in the form of loops.

New according to the second variant is that slings, bonded upper ends in the bond passed through the ears, made on the external ends of the rods, with possibility of sliding in her ears, stretched from the ears and fixed bottom ends near the near the ends of the rods, canvas planted on the branches of the sling, located between the place of their fastening and ears rods, and also on branches of the lines between his ears and a place of fastening of their lower ends. This lifting trap is also used as a small vertical benthic network.

The lower ends of the sling can be fixed to the Central articulating tool.

For faster "collapse" traps sling system, it can also optionally include the Central sling, the lower end of which is fixed on the Central articulating vehicle, and at the upper end of which is fixed guide Bush with a through hole or crossing holes, slings skipped with the possibility of movement through the hole or holes in the guide sleeve its branches are located from the place of fastening to the point of connection with the external ends of the rods.

Swivel neighbors ends of rods with the Central pivot tool can also be performed elastic.

The ears may be in the form of loops.

The simplest design of the trap contains two cores, aimed in diametrically opposite directions in working position traps.

Central pivot tool also can be in the form of the Central sinkers with the hinge elements on the number of cores. The rods near the outer ends and/or neighbors ends can be supplied with peripheral sinkers, total weight of which is less than the mass of the Central sinkers.

On the third and fourth options, as its prototype trap contains a skeleton from bars, which articulated joints their neighbors ends with a Central control means, as well as sling system for landing paintings and lifting traps, including slings fastened to the top ends in a place bonding and United with external ends of the rods, and the lines connecting consistently outer ends of the rods, and less rods planted canvas.

New the third alternative is that that slings, bonded upper ends in the bond passed through the ears, made at the outer ends of the rods, with possibility of sliding in her ears, and fixed bottom ends consistently at the ends of the neighboring rods, and the resulting branch of the lines between the external ends of the rods planted canvas. Such a system sling allows you to shoot with a skeleton canvas for the extraction of the caught fish or other aquatic organisms.

New on the fourth draft is. that additionally contains a vertical canvas planted on the branches of the sling, located between the place of their composition and the place of connection with the external ends of the rods, but also at the bars, the ends of which are connected to the mentioned lines. Thus, one canvas performs the function of a horizontal bottom of the network, and the other vertical network, which not only increases the reliability of determination of the moment of the strike, but also the reliability of retention in a trap caught fish or other aquatic organisms.

The invention is illustrated by drawings. Figure 1-5 presents vertical trap, with the figure 1 in the axonometric presented its front view in the working position, figure 2 - front view at the moment of the beginning of folding, figure 3 and figure 4, respectively front and side view in the folded position, and figure 3 - General view of the guide sleeve traps. Figure 6-9 presents the combined trap, 6 in axonometry presented its front view in the working position, figure 7 - total view of the guide sleeve traps, figure 3 and figure 9 - kinds front in two different States in the folded position.

The invention is illustrated by examples.

Example 1. Vertical trap.

Before entering the water, for example through the hole in the ice of the pond diameter 100-110 mm, trap stack, as shown in figure 3, 4, and holding the hand of the loop 5 lowered to complete immersion through the hole, and then released. After the Central sinker 8 reaches the bottom, the trap begins unpack (see figure 2) due to flatten the intense hinges 13 and, accordingly, cultivation in opposite directions rods 6 canvas 9 begins to unfold, after all lower elements traps reached the bottom of the reservoir, pick up the slack suspension rope 1 (see Fig.1), for example, by adjusting the stop float (not shown), and trap finally disclosed so that canvas 9 forms a triangular vertical network. After the network gets fish, for example, honing in on the cell gills, float begins to respond, start pulling up lifting cable 1. Net slings 2 are drawn up through the holes 3 the guide sleeve 4 and loop through 5, starting from the bottom of the reservoir rise more light weights 12 (see figure 2) before closing the loops 5 near guide bushing 4 (see figure 3) with the formation of pockets canvas 9 (see figure 4)that securely hold caught fish. The last from the bottom rises Central sinker 8, then the trap with the fish pulled through the hole to the outside. To retrieve the caught fish trap laid out (see figure 1).

Example 2. Combined trap "Grasper".

Trap for fish (see figure 6), as well as used for catching crabs, crayfish, etc., includes the same elements as the trap of example 1, and also contains additional elements. In particular, the trap contains four net slings 2, skipped through, respectively, four holes 3 the guide sleeve 4 (see Fig.7), four rod 6 and canvas 15. Such canvas 15 with a square cell, 18 x 18 mm made of a cord twisted two capron threads with a diameter of 0,3 mm green. Each sling 2 skipped from the place of fastening on the hub 4 sequentially through the hole 3 of the guide sleeve 4, loop 5 6 and one rod fastened the other end of the loop 5 neighbouring along the rod 6, and its canvas 15 pulling on branches sling 2, located between adjacent loops 5, below rods 6. Each of the two net paintings 9 strained l-shape in terms of using the two branches of the sling 2, located between two loops 5 neighboring rods 6, two additional net sling 16 (which in turn is fixed ends hinges 5 and the appendage 7), and the Central sling 10 is passed through a cell in the middle of net paintings 9. In working position traps net canvas 9 form four mutually perpendicular to the vertical grid.

The principle of action traps "Grasper" is similar to that described in example 1. However, there are a number of features. After the Central sinker 8 reach the bottom and trap degraded (see Fig.6) by straightening the intense hinges 13 and, accordingly, the cultivation of rods 6 on the diagonals the relative square, canvas 9 forms the four rectangular vertical network, and canvas 15 forms a square horizontal network, lying on the bottom. After the network gets fish, such as hitting or tripped over cell canvas 9, float begins to respond, start pulling up lifting cable 1. Trap closed (see Fig.8) with the formation of pockets canvas 9, and canvas 15 forms a bag, which covers the outside of the elements traps, securely hold inside a fish caught. Extract fish can be in two ways. First, the simple decay traps (see Fig.6). Secondly, the tightening of a down-shopping bags, educated canvas (see figure 9), for which a trap in the position shown in Fig.8, keep one hand on the density of the guide sleeve 4 loops 5, and the other hand to pull down the canvas 15. The net slings 2 also drawn down through the holes 3 and loops 5, and when this falls below the Central sinkers 8 on four U-shaped branches of net sling 2, whereby each branch is placed between adjacent loops 5 (see Fig.9). The caught fish is from the shopping bags.
