  • Publication number: 20110088308
    Abstract: A mole trap has a tough plastic base with downwardly extending fixed blades. Movable plastic blades are pivotably connected to the base and urged into a sprung condition by springs. A two-segment lever extends between the base and a catch which is pivotably mounted to the base. A trigger extends through a central opening in the catch and has a post which protrudes beneath the catch where it can be actuated by the targeted mole. Operation of the trigger post causes the lever to release from its engagement with the catch so that the movable blades close on and strike the mole positioned beneath the trap. The trigger has a release tab extending from the lever, allowing convenient release from the set position, and an upwardly protruding set arm allowing trigger depression from a point exterior to the handle into its desired set configuration.

  • Patent number: 6832447
    Abstract: The trap (42, 82) is based around a spring mechanism (24, 60) comprising a substantially rectangular sheet of spring material folded to be substantially C-shaped in cross-section. In one embodiment (FIG. 6), portions (64, 65) of the spring mechanism (60) are adapted to be killing surfaces. In another embodiment (FIG. 2), the spring mechanism (24) is provided with arms (28, 29) that support jaws (36, 37). A setting mechanism (53/54, 77) holds the spring mechanism (24, 60) in an armed position and the trap (42, 82) is triggered when a trigger mechanism (49, 75) is moved by an animal which in turn disengages the setting mechanism (53/54, 77) and allows the killing surfaces (portions 64, 65) or jaws (36, 37) to come together on the animal therebetween.

  • Patent number: 6099381
    Abstract: A catching toy includes a container having a first container body and a second container body which is relatively movable to the first container body. The first and second container bodies are configurable in a first state in which the container is opened and a second state in which the container is closed to form a chamber which is large enough to contain an object to be caught. A biasing member biases the second container body to the second state when the container is in the first stage. An engaging member engages the second container body with the first container body to keep the container in the first state. A releasing member releases an engagement of the first and second container bodies to change the container in the second state, by a contact with the object to be caught so that the object is entrapped in the chamber of the container.

  • Patent number: 4780984
    Abstract: An animal trap adapted for outdoor use to catch relatively small game animals and particularly adapted to be attached to a tree, post, or the like upstanding support and to be used independently of the height of snow and of other unfavorable ground conditions. This animal trap has a fixed jaw and a movable jaw. A bracket with arms projects away from the plane of the fixed jaw. The movable jaw is pivoted to an operative position angularly upwardly relative to the fixed jaw. A detent lever is pivoted between the arms of the bracket with an outer end forming a catch portion intercepting the movable jaw and holding it in operative position. A pair of spring wires operatively bias the movable jaw and cooperate with a chain to attach the trap to a tree, post, or the like, and the bait is attached to the detent lever to pivot the latter and release the movable jaw that then closes against the fixed jaw under the action of the spring wires.

  • Patent number: 4492056
    Abstract: The present device is an improved stand and trigger mechanism for a body gripping trap, having first and second rectangular frames which are pivotally mounted to each other for pivotal movement about a horizontal axis from a set position to a sprung position. Springs yieldably bias the frames from the set position to the sprung position. The rectangular frames each have a horizontal member, and the horizontal members of the two frames are in adjacent spaced relation to one another when the frames are in the set position. The horizontal members move away from one another as the frames move from the set position to the sprung position. The release mechanism comprises a trigger frame positioned between the horizontal members, and a pair of trigger arms mounted to the trigger frame for pivotal movement about a horizontal axis.

  • Patent number: 4424640
    Abstract: A binary animal trap comprising a frame housing and a separate jaw carriage adapted to be releasably coupled to the housing. An internal, primary trigger assembly may be set to temporarily, yieldably latch the jaw carriage within the frame assembly. Thrust springs which are maintained in a compressed position when the trap is in the "set" mode will rapidly expel the carriage when the trap is triggered. The carriage preferably comprises a pair of cooperating jaw members which are activated by jaw springs released by a second trigger system only after activation of the primary trigger assembly. When the trap is in the "set" mode the carriage jaw members rest upon the primary trigger means, and contact by an animal with the jaws activates the primary trigger. Substantially contemporaneously with expulsion of the jaw carriage from the separate housing, inertial contact of the jaws with a portion of the jaw springs results in complete release of the jaw springs, forcibly snapping the jaws shut.

  • Patent number: 4175350
    Abstract: An animal trapping apparatus has a pair of box-shaped jaws that are held in a closed position by a biasing means at one of their ends and which are retained in an open trigger set position, against the force of the biasing means, by an actuator rod that extends between the other ends of the jaws. A sensitive triggering device for this trap is achieved by positioning the lower bait carrying end of the rod for pivotal rotary movement on the inner base surface of one of the jaws and by providing a bent catch portion on its upper end that is readily disengageable from the other jaw whenever a slight contact is made with its bait retaining end and simultaneous turning of the rod on the inner base surface occurs.
