Lobster description

FIELD OF THE INVENTION

This relates to lobster traps.

BACKGROUND OF THE INVENTION

In the past, as is perhaps well known, many many lobster traps are utilized. Often these lobster traps are made of wooden materials composed of spaced members defining an open work construction which are somehow secured together, as by fasteners. Conventionally, such traps include an opening with an interiorly extending net defining a guide through which lobsters creep to be captivated within the interior of the open work construction for removal subsequently through an access door.

OBJECTS OF THE INVENTION

This invention has an object the provision of a trap which is composed of a body of one-piece molded plastic construction which is rigidified by reason of structure configurations as described more fully hereinafter and which is provided with an interior trap having a fall-through opening for a lobster creeping along the guide way which terminates at a location spaced from the walls, top and bottom, so that a lobster falling from it will be trapped within the main chamber of the lobster trap and wherein an access door with a keeper is provided for removing lobsters trapped by the device.

It is another object of this invention to provide a lobster trap of the type described hereinafter which is simple in construction, inexpensive to manufacture, well adapted for the purposes for which it is intended, is composed of a body of rigid molded plastic material, preferably polyethylene which may or may not have carbon black in it as a pigment which seems to attract lobsters, and generally, is of such a construction and material so that barnacles do not adhere to it, sea turtles cannot smash it, like often happens with wooden lobster traps, because the polyethylene is relatively rigid and somewhat bendable so as to yield to impact and which is long-lasting and which may be readily seen beneath water by reason of the black color in the embodiment in which the same is used and which is generally in accordance with the purposes which will become apparent hereinafter.

In accordance with these and other objects which have become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings in which:

DESCRIPTION OF FIRST PREFERRED EMBODIMENT

Referring to FIGS. 1 through 4 wherien like reference characters designate like or corresponding parts throughout the several views and referring to FIG. 1 a lobster trap, generally designated by the numeral 12 is illustrated. It comprises a hollow body of relatively rigid molded one-piece plastic construction. It encloses a chamber, the body defining a top 16 a bottom 18 ends 20 and 22 and front and rear walls 24 and 26 which are joined together. Each of the walls has a plurality of holes 28 spaced from one another some of which are shown but it is understood that the same are throughout the body so that an openwork molded one-piece plastic construction is defined. The ends and front and rear walls are provided with a peripheral bead, see FIG. 3 as at 29 and 31 which bead is adjacent and somewhat above the level of the bottom, and preferably about one-fourth of the overall height in the illustrated embodiment. In the embodiment, the walls taper convergingly upwardly and downwardly from this bead to the top and bottom respectively. As best seen in FIGS. 1 and 3 the upper tapered wall portions and the top are generally corrugated defining a wall and top rigidifying pattern in relief. This pattern in relief is composed of debossed or depressed inwardly spaced zones which extend generally vertically in the case of the walls and laterally in the case of the top and are contiguous or joined. In the case of the side walls, such as 33 these inner strip zones are connected to the outer main wall surface by outwardly converging zones, such as 35 on opposite sides of the main outer surface strip zones such as the one on which the numeral 31 is located; and, as in the case of the top, the outer zone is designated by the numeral 83 while the inner depressed strip zone is designated by the numeral 81 and the inner and outer zones are joined to one another as by the connector strip 85. Similarly, the bottom and the lower zone of the side walls are provided with a rigidifying pattern in relief in the central zone between the end walls 20 and 22 and side walls 24 and 26 the depressed or inner zones being designated by the numeral 39 see FIG. 1 and the outer zones being designated by the numeral 37.

Referring now to FIG. 3 in the top, a central trap opening is defined, and it is bounded by a skirt composed of downwardly converging inner partial walls 30 and 32 and 34 and 36. These partial walls lead to a flap 40 which from the top appears as a slitted floor, see FIG. 4 which is, preferably, inclined as shown. The floor is a hinge flap which is bendable in response to a downward force such as the weight of a lobster and it is composed of parallel strips 40 by providing slits in the panel 40 as best seen in FIG. 2 which extend to the hinge axis of the flap at 38.

The top is also provided with two openings 42' and 44; these access openings are for removing lobsters from the trap. The access openings are outboard of the central opening and each is provided with a short depending skirt extending into the body, each skirt has an open end and in each skirt there is a pair of aligned holes 71 and 71', see at the upper left of FIG. 3. Each of these access openings is provided with a door such as 50 and 52 each of which is sized to fit in closing relation of one of the openings and is now to be described.

Referring to FIG. 2 the left side door 50 includes a pair of spaced members 51 and 52 each of a length greater than the span of the opening 50 such as 70 and 72. These members 51 and 52 are normally slidably captivated beneath the trap body top in the skirt holes such as the end 70 in the hole 71 of the partial wall skirt beneath the top as shown by the dotted lines in FIG. 2. The spaced door members are connected together by spanning members, such as that on which the numeral 50 appears on the left of FIG. 2 and secured together as by the fasteners 53 in effect defining as openwork door. A pivotable keeper 66 in the case of the left-hand door in FIG. 2 and 68 in the case of the right-hand door in FIG. 2 are provided. The keeper is pivotally connected to the door on a pivot pin, such as that designated by the numeral 67 for rotation in the direction of the arrowed lines. The door is loosely hingedly connected to the body as by the tie of rope or strand 60. For access, the doors may be moved toward one another, with the member 70 slidably moving within the opening such as 71 see at the upper left of FIG. 3 and the latch 66 is pivoted out of the way, in the case of the door 50 for gaining access to the interior of the trap for removing lobsters therefrom.

With respect to the bottom, the central zone 73 is raised somewhat, see FIGS. 3 and 4 so as to define outer corner feet, such as that designated by the numeral 18 in FIGS. 1 and 3 and, as shown in FIG. 2. In these corner peripheral zones, such as 21 and 23 or feet weights if desired may be positioned to keep the trap on the bottom.

In use, the trap is positioned in water with the doors closed. A lobster attracted by bait within the openwork construction of the plastic strap, will enter the mouth, see FIG. 4 and since the skirt walls converge downwardly soon be on the inclined flap-type floor of strip construction 40 continually urged, by the incline thereof, see FIG. 4 to the relatively weak end zone for hinged movement with the strips about the hinge 38 where the strips are connected to the wall 30.

The lobsters thus trapped may be removed by manipulating the doors in the manner described above.

DESCRIPTION OF SECOND PREFERRED EMBODIMENT

This embodiment, see FIGS. 5-8 of the lobster trap 101 is composed of a top generally designated by the numeral 103 bottom 105 end walls such as 107 and 109 and front and rear walls 111 and 113 which are rigidified by the deformed or generally corrugated one-piece molded relatively rigid plastic construction defined in connection with the embodiment of FIG. 1. The peripheral bead 112 is provided also, as described with reference to the first preferred embodiment. The top is provided with a cutout 115 with a depending skirt 122 having slots, see 124 in FIG. 8. The cutout portion from the top is utilized as the door 116; and it is foreshortened somewhat yet sized to be maintained in use in generally closing relation of the cutout 115 by members, such as that designated by the numeral 118 and 118', having and end 123 see FIG. 8 receivable slidably within the slot in the skirt 122 for adjustable movement to clear it when the latch 120 is pivotally rotated, see FIGS. 6 and 8. It is thus seen that this type door may be completely moved by manipulating it after the keeper or latch 120 has been pivoted out of the way.

Referring now to FIG. 8 generally cone-shaped nets 130 and 132 which are generally inwardly converging, are provided; and one of each is secured peripherally as at 125 and 126 about an opening in the front and rear walls. It will be seen that the mouth 134 of each net is generally upwardly facing. Hence, a lobster attracted by bait within the trap will enter through the opening to the boundry zone of which the net is tied bounded as at 125 and 126 creeping up one of the nets 130 or 132 and falling into the trap over the brink edge at the mouth 134 or see FIG. 5 133. The nets are secured together by a tie line 135 so as to be taught. A lobster creeping through one of the nets will fall into the main chamber or interior of the lobster trap. Irrespective of which manner in which the lobster enters the trap, he will again be attracted by bait along an interior net 140 see FIG. 7 which spans the left-hand side of the trap, see FIGS. 5 and 7 and traveling upwardly across the cone-shaped net 140 and through the mouth 142 which is held in an open position by the tie lines 144 and 146 becoming trapped in the left-hand side interior of the trap. It is thus seen that a dual trapping mechanism of simple construction is provided for lobsters by this construction.

DESCRIPTION OF THIRD PREFERRED EMBODIMENT

In this embodiment, see FIGS. 9-12 the trap body 202 is of generally similar construction to that described on reference to the first and second embodiments and is provided with an opening in the top closed by a hingedly connected door 204 the door being connected to the body by means of hinge straps, such as 206 of flexible material which are secured at their ends, as at 207 and 208 to one edge of the door for swinging opening movement of it. A keeper 210 is provided and includes the tie strap 212 for tying the door in a closed position or releasing it for hingedly opening it. The keeper 210 being secured to the top, as seen in FIG. 11 and a flap may be provided on the swing edge of the door, see 213. Within the trap of this embodiment, which is somewhat dome-shaped as shown in FIG. 12 but still of the same rigidified construction described above, nets 248 and 250 extend inwardly as shown in FIG. 12 from front and rear openings, such as that designated by the numeral 260 in FIG. 11 to an upwardly opening mouth, such as 256 and 258 with the nets being secured together by tie means 262 so as to keep them taut. A lobster entering the trap attracted by bait, will find himself within the body. Once again such a lobster will further be attracted by the bait to travel thereafter through the secondary interior net 280 and out the mouth 282 into the interior dual trapped zone at the left-hand side of FIG. 11.

It is thus seen that there is shown three preferred embodiments of a one-piece molded rigidified trap construction made of relatively light-weight corrosion resistant rigid plastic construction for a lobster trap which is provided in each embodiment with a door for gaining access for removing lobsters trapped within it and which includes cutout zones spanned by a net-type or trap-type member through which a lobster is able to pass into the interior of the trap to be captivated and, in the case of the second and third embodiments, into a second trapped zone presenting in either case a tortuous path to escape which cannot be surmounted and further that the trap includes access doors for removing the lobsters thus trapped.

While the instant invention has been shown and described herein in what is conceived to be most practical and preferred embodiments, it is recognized tht departures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent apparaus and articles.
