DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.

[0026] FIGS. 1-5 illustrate a trap 100 according to the invention for catching crustaceans such as lobsters, crabs, langoustine and/or thenus and related species. The trap includes a trap frame 10 and at least two trap ends 20, the trap frame 10 and the at least two trap ends 20 being connected in a manner that creates an enclosed three-dimensional shape that is sufficient in size to hold the creatures that it is intended to catch. The trap ends 20 may be referred to herein simply as ends for the sake of brevity.

[0027] More specifically, the trap 100 shown in the first embodiment is approximately in the shape of a triangular prism. The trap frame 10 includes three sidewalls 11 that include a first sidewall 12, a second sidewall 14, and a third sidewall 16, each sidewall 11 having four edges and approximately being in the shape of a parallelogram. The sidewalls 11 are connected to one another in a manner that creates an approximately triangular prism shaped object with a first frame end 17 and a second frame end 19. Both frame ends 17, 19 are open ends on the trap frame 10. The at least two trap ends 20 include a first trap end 22 and a second trap end 24, both trap ends 22, 24, being approximately triangular in shape. To create an enclosed trap 100, the trap ends 22, 24, are attached to the frame ends 17, 19.

[0028] In the embodiment shown in FIGS. 1-5 the frame 10 is made from a single piece of bendable material, such as a wire, bendable metal, or moldable plastic. There is a slight radius R where the frame 10 is bent into its V shape. The radius may or may not be present depending on the type of material chosen and how pliable that material is. Typically, when present, this radius measures one to three inches.

[0029] Some materials, in particular certain plastics and metals, are difficult to bend at a suitable radius, and so a flat section 13 may be needed at the bends in the approximately triangular shape, as shown in FIGS. 6 and 7. While this embodiment is still approximately triangular in shape and has all of the advantages of the other embodiments, the frame 10 may be considered a six-sided structure. This flat section 13 is constructed using conventional means during the bending or molding process.

[0030] Alternatively, the sidewalls 11 may be separate panels that are connected by conventional means such as welding or using fasteners such as hog rings. When the sidewalls 11 are separate panels it is likely that there is little to no radius at the points of the sidewalls, as shown in FIGS. 8-10 and 12. The sidewalls 11 may also be constructed in manner that allows small gaps G as shown in FIGS. 8 and 9. FIG. 8 in particular illustrates an embodiment where a sidewall 11 includes two panels, 11A and 11B, which are connected by a bridge 15 that leaves a gap G. The gaps G may be advantageous to allow for the drainage of water and/or to allow small sea creatures to exit the trap 100. The bridge 15 may be any suitable connector, such as a piece of wire or metal that is affixed to both panels using conventional means such as welding or conventional fasteners such as hog rings.

[0031] The triangular ends 20 are approximately equilateral triangles. The ends 20 may be affixed to the trap frame 10 such that they act as end walls, or the ends 20 may be attached by one or more conventional hinges 26 such that they act as gates and allow a user and/or crustaceans access to the inside of the trap 100. More specifically, the ends 20 may be hingedly attached or constructed to flex internally, such as with the end gates shown in FIGS. 10 and 11A-11C, or to slide away on one or more conventional rails 28, shown in FIG. 12, thereby allowing the catch to be decanted. As such, the ends 20 do not make a substantial contribution to the structural integrity of the trap 100, on the contrary, it is generally the trap frame 10 that supports the shape of the trap 100.

[0032] The trap frame 10 and ends 20 may be produced from ferrous, non-ferrous or plastic, mesh, such as is shown in FIG. 1, where the ferrous/carbon steel wire is likely to be coated in a polyvinyl carbonate. In this embodiment, the trap frame 10 and ends 20 are connected to one another using conventional means such as, for example, cable ties, hog rings, compression fittings or the like, or welded together. There are number of conventional wires that may be used having different gauges and/or diameters, with 8 gauge through to 18 gauge wires being most common and applicable.

[0033] The trap frame 10 and ends 20 may also be a largely solid material, as shown in FIGS. 2-4, preferably of a specific gravity greater than 1.0 so that ballast might not be required to sink the trap, and having one or more openings 30 to allow marine creatures to enter the trap. In this embodiment the trap frame 10 and ends 20 are also connected to one another using conventional means, such as welding or other mechanical means such as those used with the wire mesh embodiment.

[0034] The trap frame 10 and ends 20 may also be a combination of wire mesh and solid materials. For example, one sidewall 11 may be solid to act as a floor of the trap with the other two sidewalls 11 being wire mesh and the ends 20 being wire mesh. Furthermore, the sidewalls 11 and ends 20 may also be bent from a single panel of mesh or formed from a plastic sheet such that there are no separate sections to attach. The trap frame 10 and ends 20 may be connected to one another in a manner that leaves little to no space between the sidewalls 11 and ends 20, or they may be connected to so as to allow a gap between the sidewalls 11 and ends 20 as shown in FIG. 8.

[0035] The size of the trap frame 10 and ends 20 may vary depending on the targeted species and the location of the fishing grounds, but in general the sidewalls 11 are likely to be approximately 20 to 24 inches in height and 30 to 48 inches in length with the ends 20 sized to fit on the ends of the connected sidewalls 11.

[0036] As previously mentioned, the openings 30, commonly referred to as heads, are placed in one or more of the sidewalls 11, or the ends 20, to allow the marine creatures to enter the trap 100. Vents 40, shown in FIG. 2, may be included if desired or required by legislation to allow juveniles of the targeted species or other smaller marine creatures to exit the trap 100. A door 50 may be included on at least one of the sidewalls 11 or ends 20 to allow a user to open the trap 100 to collect the catch and/or replenish the bait. The door may be attached using conational means such as hinges 52 or hog rings and likely has a latch 54 to secure it in a closed position when fishing.

[0037] Heads 30 of a conventional construction and vents 40 may also be provided in each of, or anyone of, the three sidewalls 11 or the ends 20. Providing heads 30 in each of the sidewalls 11, as shown in FIG. 1, allows the trap to function effectively regardless of which sidewall 11 lands on the ocean floor, and as such the traps 100 do not require the traditional ballast that is conventionally used to deploy the trap in a functional orientation as it is likely to fish in any position in which it lands.

[0038] This approximately triangular shape of the trap 100 reduces the amount of deck space needed to transport a number of traps by approximately forty percent when compared to conventional traps of similar width, length, and height dimensions. The shape of the trap also result is significantly less drag, thereby reducing or eliminating the need to add ballast in order to help the trap hold its position when it is submerged. The reduced trap size and lack of ballast may reduce the weight of the trap to about twenty percent of a conventional trap, enabling safer and more cost effective fishing.

[0039] It is understood that the embodiments described herein are merely illustrative of the present invention. Variations in the construction of the trap may be contemplated by one skilled in the art without limiting the intended scope of the invention herein disclosed and as defined by the following claims.
