The present disclosure is related to mole traps. Existing mole traps usually have externally exposed components, including the trigger mechanism, that can lead to unwanted tripping of the device by inadvertent contact when the trap is set and installed. The exposed components also increase the danger to children and pets who may wander too close to the device. Exposed mechanisms can also create a danger for the operator when setting the device. Further, mole traps that have spikes or tines above ground level when the trap is set, also create a danger to children and pets. Also, mole traps having various exposed trigger mechanisms can be difficult to set.
The present invention is not limited to the particular details of the apparatus depicted, and other modifications and applications may be contemplated. Further changes may be made in the device without departing from the true spirit of the scope of the invention herein involved. It is intended, therefore, that the subject matter in this disclosure should be interpreted as illustrative, not in a limiting sense.
The present disclosure, in one aspect, describes a mole trap that includes a spring loaded tine assembly; a molded housing substantially encasing the spring loaded tine assembly; and a trigger mechanism, substantially encased by the molded housing. The mole trap trigger mechanism is settable to hold the spring loaded tine assembly in a set position and operative to release the spring loaded tine assembly in response to a trigger force applied to the trigger mechanism. Setting the trap is very simple and involves only pulling the spring loaded tine assembly upwardly. Other advantages will be apparent to those skilled in the art.
The mole trap molded housing may include a first molded housing portion and a second molded housing portion which may be, in one aspect, substantially symmetrical to the first molded housing portion. The first molded housing portion and the second molded housing portion may be connected by a plurality of fasteners, that may include threaded fasteners and complementary holes, snap fit connections or the like. In embodiments where the molded housing portions are substantially symmetrical, the molded housing portions may include mating recesses on their internal surfaces for encasing the trigger mechanism.
The mole trap herein disclosed may be operated by pulling upwardly on the tine shaft of a spring loaded tine assembly until a protrusion of a release plate engages the tine shaft; and slightly lowering the tine shaft of the spring loaded tine assembly until an edge of the body engages and rests within a trigger slot. That is, a tine body surface rests against a bottom portion of a slot within a trigger lever. A protrusion of a release plate rests adjacent the upper end of a first shaft that is attached to the trigger pad. The mole trap is initially installed in the ground by positioning two ground spikes into the ground on opposite sides of a mole tunnel such that the mole trap straddles the mole tunnel, and such that the trigger pad of the mole trap contacts the ground surface on top of the mole tunnel.
In one embodiment herein disclosed, a mole trap has a molded housing including a first molded housing portion and a second molded housing portion, wherein at least one of said first and second housing portions includes at least two molded posts; and a trigger and a release plate, each being pivotally mounted upon one of the at least two molded posts. The trigger and the release plate are substantially encased within the molded housing. The mole trap molded housing portions may also each include fasteners, that may include threaded fasteners and complementary holes, snap fit posts and snap fit holes or the like, such that the first molded housing portion may be connected to the second molded housing portion to assemble the molded housing.
The trigger and the release plate may each include a post hole such that the trigger is pivotally mounted by sliding the trigger post hole over one of the two molded posts. Similarly, the release plate is pivotally mounted by sliding the release plate post hole over one other of said at least two molded posts. Among other advantages, no additional hardware is required to mount the trigger and release plate within the molded housing. The release plate has a portion positioned such that a change in the pivotal position of the release plate causes the release plate to release the trigger such that the trigger also pivots to release a spring loaded tine assembly. The release plate may also include a biasing element connected thereto for selective engagement with the trigger to bias into an unset position and to help unlatch when triggered.
In some embodiments, the mole trap internal area of at least one of the first molded housing portion and the second molded housing portion includes recesses for encasing the trigger and the release plate so that the trigger mechanism is not exposed. Recesses may also be provided to receive a spring loaded shaft of the spring loaded tine assembly.
The mole trap molded housing also provides an archway and/or cup configured to allow a spring loaded shaft to be placed in a set position when a compression spring is placed in a compressed position and such that the spring loaded shaft is operable to move longitudinally within the archway as the trap is sprung.
The first molded housing portion and the second molded housing portion may be substantially symmetrical or substantially identical in some embodiments.
A mole trap in accordance with one embodiment may include a first shaft and a spring loaded second shaft. The first shaft is connected to a trigger pad and is slideable with respect to the spring loaded second shaft. The spring loaded second shaft is connected to a plurality of tines. The mole trap also includes a release and a trigger, wherein the release is operative to hold the trigger in a set position. The trigger is in turn operative to hold the spring loaded second shaft and the plurality of tines in the set position. The first shaft is operable to displace the release in response to upward force applied to the trigger pad, and the release is in turn operable to release the trigger in response to the displacement. The trigger is operable to release the spring loaded second shaft which drives the plurality of tines into the mole burrow. The mole trap embodiment may include a molded housing substantially encasing the release and the trigger. Only a test tab, which is actually a portion of the release plate, may protrude through a slot of the molded housing when the trap is in a sprung or set position. The user pushes the test tab downwardly when testing the trap in the set position.
The mole trap molded housing may include first and second molded posts internal to the molded housing, where the release is pivotably mounted on the first molded post, and where the trigger is pivotably mounted on the second molded post. The molded housing may consist of a first molded housing portion and a second molded housing portion connected together by a plurality of fasteners, including threaded fasteners and complementary holes, snap fit connections or the like.
In some embodiments, the first molded housing portion and the second molded housing portion may be substantially symmetrical. Further in some embodiments, the first molded housing portion and the second molded housing portion may be identical.
In some mole trap embodiments, the release includes a protrusion that is operative to engage an upper end of the first shaft when the trap is in the set position. The first shaft is operable to displace the release by sliding upwardly with respect to the second shaft to displace the protrusion by pushing it upwardly in response to pressure upon the trigger pad. The release may also include a recess for engaging, and holding in place, the trigger when the mole trap is in the set position. The release is thereby operable to pivot in response to displacement of the first shaft, and thereby displace the slot to release the trigger.
The trigger includes a trigger slot for holding the spring loaded second shaft in the set position. The trigger also has a portion fitted to engage the recess of the release, so that it may be held in place by the recess of the release when the trap is in the set position. The trigger is pivotable in response to displacement of the release, and the trigger pivoting action releases the spring loaded second shaft, when displacement of the release disengages the trigger from the slot of the release or when the test tab is actuated.
The embodiments disclosed also provide a method of operating a mole trap, which includes pulling upwardly on a spring loaded shaft and tine assembly; and lowering the spring loaded shaft and tine assembly until a portion thereof engages in a slot of a trigger and is held in a set position thereby.
It is to be understood that terms used herein such as “first,” “second,” “left,” “right,” “upper,” “lower,” etc., are relational terms useful for describing the position or location of various components relative to others and that this language is used herein for such descriptive purposes only and is not to be in any way considered as imposing limitations on the various embodiments herein described. Further the terms “operable to” and/or “operative to” as used herein, particularly as used within the claims appended hereto, indicate that the various components of the mole trap herein described may be positioned, or, in other words, set, in a “trap set” or sprung to be in a “trap sprung” (or “tripped”) position. That is, the various components are each “operative to” or “operable to” be set or sprung and/or, to operate so as to interact with various other components as described in detail herein.
Turning now to the drawings, wherein like numerals represent like components,
For the embodiment illustrated in
The second trap housing portion 102 also includes recesses that may be symmetrical or identical to, and match up with, recesses within the first trap housing portion 101. That is, the recesses are matched up when the first trap housing portion 101 and second trap housing portion 102 are fit together. For example, the first trap housing portion 101 may further include a trigger recess 109. It may also include an opposite side trigger recess 110. As will be described further, the trigger mechanism 300 may be installed on either the second trap housing portion 102 or on the first trap housing portion 101 since both portions are symmetrical or identical as described herein. For the present example, the trigger mechanism 300 is shown installed on the second trap housing portion 102. The trigger recess 109 and side trigger recess 110 are formed on the first trap housing portion and substantially encase the trigger mechanism The second trap housing portion 102 further includes a tine shaft recess 111. The second trap housing portion 102 also includes an archway 115 wherein the tine assembly 200 may move between a set and sprung position. It is to be understood however that some embodiments may not have symmetrical and identical housing portions. For example, some embodiments may provide all recesses, such as the trigger recess 109, in only one portion, while the other portion of the housing seals the recesses when the two portions are joined and assembled.
In one embodiment, another post 302 is connected to the first trap housing portion 101. As shown in
In
The mole trap embodiments described above provide various advantages for manufacturing that would be readily apparent to those of ordinary skill. For example, the components of the trigger mechanism 300 may be easily fabricated by die-cutting etc. Mounting of the trigger and release plate is fast and easy because these components are simply fit over a plastic mounting post, or a dowel pin, of the housing which requires no tools. Additionally, for embodiments employing snap fit connections, no tools are required to assemble the mole trap housing. As discussed above, setting the trap is also simple and involves only the pushing of the test tab 127 and pulling the pull handle 204 upward. Because the trigger mechanism is enclosed in the housing, the user's fingers are in no danger of becoming entangled or pinched by the mechanism or by inadvertent tripping of the trap. Therefore, the mole trap of the various embodiments provides a safety advantage over previous designs.
Therefore a mole trap and method of operation have been disclosed herein. Other variations that would be equivalent to the herein disclosed embodiments may occur to those of ordinary skill in the art and would remain in accordance with the scope of embodiments as defined herein by the following claims.
