Definitions

  • the present invention relates to a trap for a small animal such as a mouse. More specifically, the invention relates to a trap having a simple mechanical construction and having minimized the risk of injury during the tensioning of the trap. Moreover, the trap of the invention makes it possible to dispose of the killed animal without the user needing to touch or come close to the animal.
  • a type of mousetrap commonly used in Sweden today comprises a clamp that is pivoted to a tensioned position against the bias of a spring. When the clamp is made free, it is pivoted towards the mouse and hits it and kills it.
  • a table with a bite is arranged in relation to the clamp.
  • a release mechanism normally maintains the clamp in the tensioned position. Upon the mouse taking the bite, the release mechanism activates the clamp and the spring pivots the clamp towards the mouse head.
  • Such a mousetrap is disclosed in for example EP 1011326.
  • US 5953853 disclose another type of mousetrap having a more complex construction, comprising electronic means for detecting the presence of a mouse.
  • US 615218 disclose a mousetrap having means for discarding the killed mouse without the need of touching the killed animal.
  • a first object of the present invention is to provide a trap having a simple mechanical construction and in which the risk of injury during the tensioning of the trap is minimized.
  • Another object of the invention is to provide a mousetrap in which the animal may be discarded without the need of the user touching the killed animal.
  • a third object of the invention is to provide a trap that is self-inhibiting.
  • a fourth object of the invention is to provide a trap that is mechanically safe, so that a cat or dog or other larger animal cannot by mistake trigger the trap and become hurt. Accordingly, there is provided, according to the invention, a trap for a small animal having the features defined in the appended patent claim 1.

  • the triggering means comprising a shaft and a tongue cooperating with a strap of the clamp means for retention of the strap and the clamp means in a tensioned position.
  • a cover is arranged above the table covering the bite and connected to the triggering means for releasing the strap and the clamp means upon activation of the cover. The cover is urged towards the table by said triggering means in the tensioned position so that the trap becomes self-inhibiting.
  • the cover itself may be the triggering means.
  • the triggering means may comprise a retention tongue made in a material different from the triggering means and attached to the triggering means.
  • the triggering means may comprise a pivotable tongue which cooperates with the strap in the tensioned position and which is pivotable out of the way for the strap during the tensioning of the trap.
  • the spring may be a plate spring or a coil spring.
  • the cover may comprise a shaft pin, and the distance from the cooperation position between the triggering means and the strap to the shaft pin, and the distance between the shaft pin and the end of the cover are so dimensioned that a lift of the cover by about 10 mm entails that the triggering means releases the clamp and the strap so that it may pivot freely.

  • the mousetrap may be placed at other supports such as inclined surfaces or even hang vertically.
  • Fig. 1 The operation of the mousetrap appears from Fig. 1.
  • the cover When a mouse puts its nose below the cover 5, the cover is pivoted upwards pivoting around a shaft pin 52 so that the trigger 6 is moved to the right in Fig. 1 and the clamp is made free from the shoulder 67 of the trigger 6. Then, the clamp 7 is pivoted clockwise by the spring 8 towards the neck of the mouse positioned before the cover 5 and kills the mouse.
  • the spring force will form a momentum in the clockwise direction around shaft pin 52 and bias the cover 5 towards the footplate or support 3.
  • the size of this force is determined by the exact position of the shaft pin 52 and the inclination of the upper surface of the shoulder 67.
  • the shoulder 67 As the shoulder 67 is worn out, it will tend to perform its retention action less well. Thus, it is desired to make the shoulder out of a durable material, such as hard plastics material or metal. Hard- plastics material is preferred since it may have a low friction coefficient as well.
  • the shoulder may as well be made from a material different from the materials used for other parts of the trap.

  • the tongue is provided with two shaft pins 61, 62 cooperating with a recess in the sidewall of the cover.
  • the tongue has two protrusions 63, 64 extending below the spring strap and preventing the spring strap and the entire clamp 7 from pivoting clockwise and down to the right in Fig. 1. Between the protrusions 65, there is a space where the end of the spring may be encompassed.
  • the tongue retains the clamp in its upright and tensioned position, as shown in the drawings.

  • the tongue may be pivoted up to the right (clockwise) seen according to Fig. 4 and leave space for the spring strap to move beyond the tongue.
  • a stop shoulder 66 prevents the tongue from pivoting more than about 80 degrees. In this manner, the tongue will always tend to achieve the position shown in Fig. 4. The operation of the mousetrap will now be explained below with reference to Figs. 11 and 12.
  • Fig. 11 discloses a front portion of a mouse that wants to take the bite and extends its nose between the cover 5 and the table 27 thereby lifting the cover. This takes place against the bias of the spring 8, since the spring urges the cover downwards towards the table with a certain force.
  • the size of the force is determined by the relationship between the shaft 52 and the influence of the spring strap 76 on the tongue.
  • a recess 27a see Fig. 9, in the table helps to release the animal. Also the fact that the cover now is free helps.
  • the recess 27a may be much deeper than shown in Figs 6 and 9, so that in principle the entire fourth side wall of the table is removed, since the foot plate 3 forms the fourth side wall, see Fig. 3.
  • the mousetrap is put on a support and the locking plate 4 is inserted to the position shown in Fig. 4. Then, the position shown in Fig. 12 has been obtained. A new bite is adapted by lifting the cover to its vertical position. Finally, the cover is returned to its horizontal position according to Fig. 12.
  • the clamp has to be tensioned or apted, which takes place by moving the clamp counterclockwise seen according to Fig. 12, until its vertical position. After about 70 degrees, the clamp and the spring strap 76 attain the position shown with broken lines in Fig. 12. A continued rotation of the spring strap entails that the tongue is pivoted upwards and to the right (clock-wise), as shown with broken lines, and out of the way for the continued tensioning of the clamp.
  • the spring strap 76 has passed beyond the tongue and the tongue is now free to pivot, under the influence of gravity, back to its position shown with solid lines in Fig. 12.
  • the stop shoulder 66 prevents the tongue from being pivoted too much clock-wise so that it will no longer tend to fall back to its horizontal position. There may be arranged a spring forcing the tongue back to its horizontal position.
  • the clamp will be self- inhibiting. This means that it is practically impossible for the mousetrap to trigger unintentionally. If the mouse trap is uncarefully handled, for example by influencing upon the beam of the clamp, the cover 4 will only be still stronger urged towards the table and the tongue will be moved still further in below the spring strap. Thus, the construction is inherently stable and cannot be activated by mistake. The only way to activate or trigger the mousetrap is to lift the cover more than about 5 to 10 mm, whereupon the mousetrap becomes instable. After lifting the cover another millimeter, the cover and the tongue makes free the spring strap and the clamp. Since the edge of the tongue always is somewhat round, the spring strap will roll off the tongue during the last portion of the movement .
  • the tongue may be constructed by a hard material like hard plastics material or metal.
  • the other portions of the trap may be made from injection moulded plastics material.
  • the clamp and the spring are made from metal.
  • the spring may be a plate spring as appears from Figs. 1 and 10, or a helical spring as appears from Fig. 12.
  • the tongue may be provided with a recess where the tongue cooperates with the spring strap so that the tongue will not unintentionally loose its cooperation with the spring strap.
  • the upper surface of the tongue cooperating with the spring strap may be somewhat chamfered.
  • the normal of this chamfered surface determines the direction of the reaction force between the spring strap and the tongue. If the normal extends to the right of the shaft pin 52, the trap is self- inhibiting according to the invention. By adjusting this surface, that is adjusting the normal of this surface, the force required to open the cover may be adjusted. The frictional forces also contributes to the action.
  • the force is also determined by the relationship between the force arms, i.e. the distance between the shaft pin and the tongue and the distance between the shaft pin and the outer end of the cover (to the right in Fig. 4).
  • the relationship between these arms may be between around 1:3 and 1:8.
  • the trap Since the trap is self-inhibiting and the cover must be lifted to a relatively distinct position before the cover is activated or triggered, the trap is safe for other domestic animals, such as cats and dogs. The trap is also secure for handling by humans, since it almost never is activated unintentionally.
  • the device has been described the use of the device as a mousetrap. However, other animals may be caught and killed by the device such as rats, voles etc.

Abstract

Cette invention concerne un piège à souris composé d'un socle sur lequel on place un appât et d'une tige (7) à ressort munie d'une barre servant à frapper la souris au moment de l'activation d'un mécanisme de déclenchement de la tige (6, 69). Une cloche (5) est disposée au-dessus de l'appât et peut pivoter autour d'un tenon (52) d'arbre. Le mécanisme de déclenchement repose sur la cloche de sorte que la tige à ressort, en position armée, pousse la cloche contre le socle et l'appât de sorte que la cloche soit auto-inhibitrice et ne puisse pas être actionnée par un animal plus gros tel qu'un chat ou un chien. Le mécanisme de déclenchement comprend un pivot (69) pouvant pivoter pour permettre à une patte de la tige de passer derrière le pivot. Ensuite, le pivot reprend sa position initiale. Par ailleurs, un seuil (3) est placé devant la cloche, lequel seuil peut pivoter et est verrouillé dans la position d'utilisation par une plaque de verrouillage (4).
