Description

Mouse trap

The present invention relates to a mouse trap, consisting of means for catching and killing any mouse which may find its way into the trap, and the mouse- receiving space of the trap is formed from a foldable sheet consisting of cardboard or some other suitable material, with a moving device capable of killing a mouse accommodated internally within said space and connected to a spring pressure device so arranged as to actuate said device for the purpose of triggering same at the moment of catching.

The principal object of the present invention is essentially to make available a mouse trap of the kind described, which is suitable for use as a disposable trap and which as such is simple and inexpensive to produce with a tripping mechanism of a unique kind which functions reliably and effectively, which trap is suitable for use without the user having to come into contact with the mouse in the trap when it has been caught.

Said object is achieved by means of an arrange- ent in accordance with the present invention, which is characterized essentially in that the mouse-killing device consists of a plate with an opening to permit passage by a mouse, along one edge of which opening there extends an element for cutting and/or strangling the mouse and that the casing of the trap exhibits an area along one side specially weakened so as to allow the spring to pass through it, which weakened area is preferably formed by the pre-perforation of the casing for an intended distance along the casing, through which one end of the spring is intended to project, upon the trap being triggered, from the internal space of the trap.

The invention is described below as a preferred illustrative embodiment, in conjuction with which reference is made to the accompanying drawings , in which Fig. 1 shows a perspective view of a trap in use;

Fig. 2 shows the outside of a flat sheet of the kind referred to, from which the trap is produced;

Figs. 3-5 show various component parts which are included in the intended trap; and

Figs . 6A-6E and

Figs. 7-12 show different stages in the assembly of a trap of the kind referred to here.

A mouse tap 1 in accordance with the present invention comprises, in a previously disclosed fashion, appropriate means for catching and killing any mouse 2 which may find its way into the trap 1. The mouse- receiving space 3 of the trap is formed from a foldable sheet 4 consisting of cardboard or some other suitable material, which is capable of being folded into the intended shape and yet of withstanding the effect of external stresses. For example, the sheet may be coated with a suitable moisture-resistant substance, at least on its outside surface. A moving device 5 , which is intended to affect a mouse 2 in such a way that it dies, is capable of being accommodated internally within said formed space 3 and is connected to a spring pressure device 6 so arranged as to actuate the moving device 5 for the purpose of triggering same at the moment of catching.

A securing device 7, which can consist of a separate component part, for example a pin which interacts with the casing 8 of the assembled trap, or which can consist of a component part which is permanently attached to the casing of the trap, for example a cut-out, etc., is included finally amongst those means from which the trap 1 is intended to be produced when same is assembled.

The assembled mouse-receiving space 3, which exhibits a closing end wall 9 at one end 1A of the trap at a certain distance from the intended entrance opening 10 to the trap, appropriately tapers in the direction of said one end 1A of the trap, preferably in the form of a wedge, and is formed from front parts 11A-15A of the enclosing wall parts 11-15 of the trap.

The trap casing sheet 4 which encloses said space thus exhibits a plurality of wedge-shaped wall parts 11-15 which are divided from one another laterally by means of folds 16, 17, 18, 19, with the illustrative example showing an arrangement of five wall parts 11-15, although wall parts of a different number and arranged in a different form can naturally be present, depending on the form of the intended trap.

A number of fixing tabs 20, 21 with matching receiving openings 22, 23 can also be arranged on a number of said wall parts 11-15, such as on one lateral boundary edge 24 of a wall part 15 and on a fold 16 between two wall parts 11, 12. Said fixing tabs 20, 21 are so arranged, once the wall parts 11-15 have been folded about the respective folds 16-19, as to be capable of being introduced through the matching tab-receiving opening 22, 23 and of being retained for the purpose of being locked in engagement.

The trap 1 can also exhibit a number of anti- tipping supports 25, 26 projecting laterally from the trap 1 for the purpose of preventing it from falling over, which supports are preferably in the form of tongues in the sheet 4 executed laterally in wall parts 12, 14 through slits.

There extends through at least one of said wall parts 13, 11, 15 a number of openings 27, 28, 29, 30, 31 so adapted as to be capable of receiving the moving mouse- killing device 5, in conjunction with which a long, slot- shaped opening 27 is intended to be penetrated fully by the device 5, whilst openings 28, 29, 30, 31 of shorter length and arranged in pairs, for example, are intended to receive and locate projecting tip-preventing feet 32, 33 arranged on the mouse-killing device 5.

Said mouse-killing device 5 consists of a plate made of a suitable material, such as plastic, metal, etc.. and is provided with an internal opening 34 to permit passage by a mouse, along one edge 35 of which opening there extends an element for cutting and/or strangling the mouse, which element may appropriately be formed by said edge itself, for example by the edge 35 being ground or in some other way arranged so as to be capable of acting against the neck 2A or some other part of the body of a mouse 2.

Said tip-preventing feet 32, 33 can be situated on the under side of the device 5 and can between them exhibit a receiving opening 36 capable of accommodating a part of said spring pressure device 6, such that the plate 5 can be attached to the spring pressure device 6, before the trap is triggered, for the purpose of guiding same internally within the mouse-receiving space 3 of the trap.

The plate 5 which functions as a mouse-killing device, with its pairs of feet 37, 38 which are executed to either side of the central opening 34 in the plate and are capable of being accommodated by the opening 27 in the trap as the plate 5 is introduced through the opening 27, is also connected to the spring pressure device 6 at a point outside said mouse-receiving space 3 of the trap.

The spring pressure device 6 can, for example, be executed from a wire-like material with pairs of spring ends 39, 40 projecting in pairs from a wire-like common spring pressure centre part 6A and one spring end 40 can be so arranged as to interact with one wall of the trap, preferably its base 13, internally within the space, both in the set position and in the triggered position. The other end 39 of the spring pressure device is so arranged as to be capable of projecting through an opening 41 in a wall part 13 of said assembled casing 8 of the trap in the set position, as illustrated in Fig. 1, 6A and 9 in the drawings, and is attached to the mouse-killing plate 5, preferably so arranged as to extend through an upper spring-receiving opening 42 in same.

The casing of the trap also exhibits a weakened area 43 allowing the spring to pass through and thus arranged first as a component which closes the mouse- receiving space 3 of the trap, which extends along the wall part 13 on one side of the casing. The area 43 which allows the spring to pass through is preferably formed by the pre-perforation of the casing 8 through one wall part 13 for an intended distance L along the casing 8, through which one end 39 of the spring is intended to project when the trap 1 is triggered from the internal space 3 of the trap in the direction of the closed end 1A of the trap.

The spring pressure device 6, which is so arranged as to be retained in position in the internal space 3 of the trap by means of a securing device 7, for example by said securing device 7 being accommodated in receiving openings 44, 45 arranged in pairs each in its own side wall part 12, 14, is forcibly actuated, with the trap 1 in a state in which it is ready to be tripped, by a wire or some other suitable securing means 46 in such a way as to be held in the sprung position I in which it is ready to be tripped, as shown in Figs. 5 in the drawings.

The function of the trap 1 should have been appreciated to some extent from the foregoing, although there now follows a brief description of the procedure for the assembly of a trap as described above and illustrated in the drawings, after having been supplied to the user in the form of a flat package containing the various components:

The cardboard sheet 4 is first folded along its said folds 16-19, whereupon one end 39 of the spring 6 is introduced from the inside 4A of the sheet 4 through the opening 41 in the direction A from the front part 4B of the sheet towards its opposing part 4C. The spring 6 continues to be introduced until the wire, etc., 46 comes up against an obstruction and can be inserted no further. The sheet 4 is then folded up about the folds

16-19 and is secured together by means of the fixing tabs, etc., 20, 21 which are introduced into matching openings 22, 23 with the spring 6 enclosed by the casing 8 thus formed by the sheet 4.

The moving device 5 is introduced from outside through the slit 27, with the aforementioned feet 32, 33 being passed through the slit 27 first, making sure that the end 39 of the spring projecting from the trap is accommodated in the opening 34 in the device 5, so that the end 40 of the spring which extends along the bottom, etc., of the trap and is situated in the assembled mouse- receiving space 3 of the trap is guided between the feet 32, 33 on the device 5 and is retained in position when the feet 32, 33 are introduced through the openings 28-31, and in this way the device 5 and the spring 6 are prevented from falling over when the trap is arranged in its said set position. The upper end 39 of the spring is accommodated at the same time in a matching opening 42 in the device 5.

The spring 6 is then secured by means of the plastic pin, etc., 7, which is introduced through the openings 44, 45 in the casing and through the hole 47 in the spring formed from turns of the spring 6.

With the trap 1 in its set state, bait of a suitable kind, for instance cheese, is then placed in the internal space 3A of the trap beyond the wire, etc., 46 which retains --said spring.

Thus, when a mouse 2 discovers the bait in the trap 1, it gnaws through the wire 46 in a familiar fashion in order to gain access to the bait behind same, in con¬ junction with which the previously forcibly restrained spring force of the spring is now free to exert its effect. In this way the upper free end 39 of the spring is caused to move away from the other end 40 of the spring which acts against the bottom of the trap, in so doing causing the device 5 to be pulled upwards through the interaction of the spring with said device 5, this being the opening 42 in the case of the example shown here, in the direction of the arrow 48, in conjunction with which the mouse 2 is choked by the effect of the edge 35 of the opening in the device or is held in some other way against the roof of the trap and is killed in a bloodless fashion, and is then discarded together with said trap 1 without the need to open the trap and to come into contact with the mouse. The means that it is possible for anyone at all to use the trap without feeling uncomfortable, amongst other things since the mouse is not visible from the out¬ side of the trap. An important effect of the trap is the afore¬ mentioned spring 6 and its attachement to the casing 8 of the trap and its interaction with same. The upper end 39 of the spring is able to move freely at the time of the trap 1 being triggered, and to move away in an upward sense and to pivot about the front spring part 6A of the spring in the direction of the arrow 49. This causes the weakened area 43 of the casing 8 of the trap to be torn apart in a direction away from the spring attachement opening 41 towards the end 1A of the trap, so that the end 39 of the spring is allowed to continue to pivot upwards in the direction of the arrow 49. Said weakened area 43, which permits the spring to exit more easily from the casing 8 of the trap, prevents access to the bait by mice from outside the trap, forcing them to enter through the opening 10 of the trap before the mouse is caught.

The assembled trap 1 adopts rectangular form in the embodiment described here, in conjunction with which one wall part 15 is positioned on top of another wall part 11, these being the two wall parts 11, 15 situated at the extreme edges of the sheet 4, although the possibility also exists for dispensing with the additional wall part 15 , and arranging locking tongues on a preceding wall part 14 and matching locking slits inside the free end edge 51 of the other outer wall part. The form of the device 5 and the internal space of the trap in the area 52 in which the device 5 acts inside the casing are adapted to one another in such a way that they align with one another essentially so that a mouse is unable to find its way through between the device and the internal walls, floor and roof of the casing.

Finally, it can be stated that two of the wall parts 12, 14 exhibit a certain width B at the front ends of the parts, whilst other wall parts 11, 13, 15 are pointed at their front end. A pointed tip to the casing of the trap is formed in this way, which extends upwards as a straight part with a gap between said wall part tips, such that the casing of the trap adopts a form similar to that of a slice of cake, but with a raised rear part.

The invention is not, however, restricted to the illustrative embodiment described above and illustrated in the drawings , but may be freely modified within the scope of the Patent Claims without departing from the idea of invention. For example, it is possible to cause the moving mouse-killing part to be rigidly attached to the spring pressure device, and also to cause it to be a part of the spring pressure device itself, for example a curved, arm- like clamping device which extends across the moving spring end of said spring pressure device.

The trap 1 can of course also be delivered with the casing 8 already mounted with the device 5 only having to be attached to the spring 6 which is shown in Fig 6C.
