Description

The invention relates to a fish trap for catching crabs, specifically to a fish trap known type, in which a network on a cylindrical frame consisting of a helical spring is tensioned, the turns of which lie against each other when the spring is compressed and in this compressed position by hooks or the like. Can be held together. The trap is on at one end or at both ends with funnel-shaped tapering, inwardly directed Provide inlet channels. These are held together by means of cords or the like, their lengths are dimensioned so that the network parts lying in the funnels when the trap is expanded through the Stretches of these cords are kept taut.

However, such traps have various disadvantages, which makes them in many cases are difficult to handle and which, among other things, significantly shortens the lifespan of the trap will. These disadvantages include the following:

The attachment or removal of the bait and the removal of the caught crabs must be done either through the entry openings or through a special hole cut out in the net, which is pulled together with a cord that has to be removed and then reattached each time. This is difficult even in daylight, but even more difficult in the dark, especially since crayfish catching happens mainly at night. Further it has been shown that the inner cords are often with each other and with the one in the trap Entangle holders for the bait and thereby cause additional work. Another Another disadvantage is that these cords are arranged in such a way that crabs get into the trap relatively can easily crawl out of it again.

The aim of the invention is to eliminate these disadvantages and at the same time make the trap easy to transport and make it packable.

In the case of a crab trap, consisting of one formed by a compressible coil spring Scaffolding and a network stretched over the spring, one or both of which faces inwardly directed, funnel-shaped tapering inlet channels, as well as with a removable one Lure feed holder inside the cage, according to the invention, at least one inlet channel is on its outer, wider end is provided with a flap which makes the inside of the cage accessible makes, and the inwardly narrower end of the entry channel by means of a number well-known tension cords held, the conically tapering entrance to the center of the cage

form passages so that they prevent the opening of the flap to the outside when the spring is relaxed, however allow it to open when the spring is compressed.

The flap is preferably through a cut part of the mesh on the inlet channel formed, with one cutting edge of this part on the spring frame and the other cutting edge on an arcuate bracket is attached, which is mounted on a pivot axis attached to the frame and can be locked by means of a locking hook provided on the frame.

In general, the oppositely directed mouths of the funnel-shaped one formed from the network Parts reinforced by rings in which indentations are directed towards the interior of the cage Od. Like. Are attached in which the tension cords are secured against displacement.

The bait holder can thus be provided with the bait outside the trap, and this can also can be removed from the holder outside of the trap, as this can be attached to a fixed position by means of a single movement of the hand Hanging device can be suspended and removed from this, which is designed so so that she cannot get tangled in the tension cords.

An embodiment of the cage according to the invention is shown in the drawings, in which Fig. 1 shows in perspective the trap without the lure feed holder;

Claims (3)

The frame of the trap consists of a cylindrical helical spring 1 over which a net 2 is stretched and which is provided with hooks 3 which grip the edges of the opposite ends of the frame 1 when the spring is compressed so that the turns of the same against each other issue. The trap is thus held in its compressed position by the hooks 3 and can be easily transported. The front ends of the trap are formed as inwardly tapering funnel-shaped inlet channels 4, 5 by extensions of the Xetzes 2. The opposing mouths of the funnel-shaped parts 4, 5 formed from the network are reinforced by means of a ring 6 in which a number of recesses 7 or the like directed towards the inside of the trap are attached, in which the tension cords 8 are secured against displacement. The tension cords 8 connect the two oppositely directed rings 6 to one another. By means of a knot 9 attached in the middle of these tension cords 8, it is achieved that they form a conically tapering entrance passage directed towards the center of the trap, which due to its shape allows unhindered access of the crabs to the interior of the trap, but at the same time allows them to exit the crayfish out of the fish trap considerably more difficult. The tapering, funnel-shaped part 4 is partially designed as an articulated flap that part (in the example shown, half) of this mesh surface is cut open and one of the two cut edges created in the process is on the spring frame 1 and the other on an arched bracket 10 is attached, which is articulated on a shaft 11 attached to the frame 1. This axis 11 also has the advantage that you can easily find the open end of the trap in the dark. The bracket 10 is held on the spring frame 1 by means of an outwardly directed \ rerschlußhakens 12, which allows the bracket 10 to pivot about the axis 11 after inward rotation, so that the inside of the trap is accessible. When the trap is set up to catch crabs. d. H. when the hook 3 is opened Mild and the spring 1 is thereby relaxed. the bracket 10, which together with part of the funnel-shaped mesh surface 5 forms the articulated flap, cannot be opened to the outside without difficulty (FIG. 2, direction A). since the tension cords 8 prevent this. Towards inward (Fig. 2. Direction B) the flap can only be opened after turning the locking hook 12, whereupon the inside of the trap becomes accessible and the contents of the crabs caught can be poured out of the trap or the bait holder can be hung up or removed. When the trap is compressed and the hooks 3 are in the closed position, after turning the hook 12, the bracket 10 can be swiveled outwards (Fig. 2. Direction A), whereby the fixed suspension device 13 is exposed and the lure feed holder is easily suspended or can be removed. The suspension device 13 extends diagonally through the frame 1 in the middle of the trap and is provided with a central eye 14 through which the tension cords 8 run with the knot 9 so that they cannot tangle with the suspension device 13. Furthermore, the latter is provided with an eye 15 and a hook 16 for attaching the removable lure feed holder. This expediently consists of a needle 17, which is designed like a safety pin, the eye end 18 of which is provided with a clasp 19 and a snap hook 20 attached to it. which is hooked onto the ring 15 ίο. The closure end of the needle 17 is formed into a larger eye 21 which enables it to be hooked onto the hook 16. Since the embodiment described is only an example, the invention could be modified. Thus, the flap could be made smaller or larger, so that the bracket 10 is also designed as a complete ring which is attached to the frame 1. Such a ring could also be completely removable and attached to the frame 1 by means of spring clips or the like. A spring clip could be used instead of the needle 17 and a spiral spring provided with hooks could be used instead of the snap hook 20. Patexta xsprγcη ε 1. Crayfish trap, consisting of one formed by a compressible coil spring Frame and a net stretched over the spring. one face or both faces after inwardly directed, funnel-shaped tapering inlet channels, as well as with a removable lure feed holder inside the cage, characterized in that at least one Entry channel (4 or 5) at its outer, wider end with a flap (10, 11, 12) is provided. which makes the inside of the cage accessible, and that the inward-facing narrower one The end (6) of the inlet channel is held by a number of known tension cords (8) is, which form conically tapered entry passages towards the center of the cage, so that they prevent the flap from opening to the outside when the spring (1) is relaxed, but allow it to open, when the spring is compressed. 2. Crayfish trap according to claim 1, characterized in that the flap is opened by a > The cut part of the network (2) is formed on the inlet channel (5). with one cut edge this Partly on the spring frame (1) and the other cutting edge on an arched bracket (10) is attached, which is attached to a pivot axis (11) attached to the frame and by means of an on Scaffold provided locking hook (12) can be locked. 3. Crayfish trap according to claim j and 2, characterized in that the oppositely directed Mouths of the funnel-shaped parts (4, 5) formed from the network are reinforced by rings (6) are in which recesses (7) or the like to be directed towards the interior of the cage in which the tension cords (8) are secured against displacement.
