Snap Trap Actuator

Abstract

The present improved animal trap and unique catch release mechanism eliminates substantial eating or removal of the bait without the trap activating and provides a dual means to activate the trap. This is accomplished by the present catch release mechanism having a sliding member which slides within a hole through the platform of the trap under the influence of gravity and a prop which holds at least a portion of the trap platform above a support surface. When the prop is destabilized by an external force, the prop's support of the platform is disturbed, permitting the platform to fall toward the support surface. The platform falls relative to the sliding member; and the sliding member is forced toward the catch by contact with the support surface, thus pushing the catch so that the catch releases the holding arm bar to activate the trap.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0046] The detailed descriptions set forth below in connection with the appended drawings are intended as a description of embodiments, and is not intended to represent the only forms in which the present securement system may be constructed and/or utilized. The descriptions set forth the structure and the sequence of steps for constructing and operating the securement system in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent structures and steps may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.

[0047] Referring first to FIGS. 1 and 2, an animal trap (20) is disclosed, generally having a wood platform (22) (although other materials may be used, such as metal, plastic, linoleum, acrylic glass, or a platform with a veneer to match the support surface, etc.) with a top surface (32) having a first section (36), a second section (38), and a middle section (40) between the first section (36) and the second section (38). The sections (34, 36, 38) are not precisely delineated, but instead, represent three general areas of the top surface (32) upon which various parts of the trap (20) may be positioned.

[0048] A bar staple (54) is located within the first section (36), with the holding arm bar (28) attached to the bar staple (54) by a loop on the end to create a pivoting attachment. Of course, because the bar staple (54) is U-shaped with the end of the holding arm bar (28) looped about it, the holding arm bar (28) is permitting to pivot and move about the bar staple (54) in multiple directions. The pivoting kill bar hammer (26) is generally made from a single wire bent into a rectangular shape, with one side of the rectangle held, much like an axle, by a first rod staple (50) and a second rod staple (52) pinned to the middle section (40) of the top surface (32). One or more springs (60, 62) (such as a torsion spring) biases the rotation of the pivoting kill bar hammer (26) towards the second section (38) of the top surface (32) with enough force and impulse to capture a rodent between the pivoting kill bar hammer (26) and the second section (38). A catch staple (42) pivotally holds the catch (24) to the top surface (32) within or near the middle section (40). The catch (24) includes a bait holder (44) and a catch hook (43) configured to engage the distal end (58) of the holding arm bar (28) when the animal trap (20) is in the set configuration, as shown in FIG. 1.

[0049] As with standard spring-loaded traps, in the set configuration, the pivoting kill bar hammer (26) is rotated from the second section (38) and towards the first section (36) against the biasing force of the springs (60, 62). As the pivoting kill bar hammer (26) is manually held towards the first section (36), the holding arm bar (28) is rotated over the pivoting kill bar hammer (26) such that the proximal end (58) of the holding arm bar (28) touches the pivoting kill bar hammer (26) to arrest its movement. Then, the distal end (58) of the holding arm bar (28) is positioned beneath the catch hook (43) so that the distal end (58) pushes up on the catch hook (43) to provide a temporary engagement. If activated, the spring force acting on the pivoting kill bar hammer (26) will cause the distal end (58) to disengage from the catch hook (43) swing back, and release the pivoting kill bar hammer (26) so that it strikes the second section (38) of the top surface (32).

[0050] The catch release mechanism (30) is illustrated more clearly in the partial cross-section of FIG. 2. The illustrated embodiment of the catch release mechanism (30) comprises a sliding member (64) positioned in a through hole (70) formed through the platform (22), from the top surface (32) to the bottom surface (34). The sliding member (64) is permitted to axially slide within the through hole (70), preferably freely sliding or with little resistance. The through hole (70) may be lined with a tubular liner made of plastic, metal, or other material that permits the sliding member (64) to slide without undue friction or binding. When the platform (22) is lifted above the support surface (S), under the influence of gravity, the sliding member (64) slides downward towards the earth. An enlarged head (74) is connected to a top end of the sliding member (64) and is positioned above the top surface (32) and beneath the catch (24). An enlarged base (76) is connected to a bottom end of the sliding member (64) and is positioned beneath the bottom surface (34) of the platform. The enlarged head (74) and the enlarged base (76) limit the travel of the sliding member (64) so that the sliding member (64) remains in the through hole (70). Further the enlarged head (74) is sized so that it pushes upon the catch (24) (preferably on the catch distal end (46) or any other portion) when the sliding member (64) slides upwards towards the top surface (32). The enlarged head (74) and the enlarged base (76) may be made of various materials, such as metal, plastic, and such. The enlarged base (76) may further include a rubber foot to enhance grip on the support surface (S). The sliding member (64) may be a rod, tube, strip, square stock, or any other configuration that permits sliding within the through hole (70).

[0051] Still referring to FIG. 2, the catch release mechanism (30) further comprises a prop (66) or other support that provides an unstable support to hold at least a portion of the platform (22) above a support surface (S). In the present example embodiment, the prop (66) is a small wood board with a tapered end (68). However, the prop may be made of a length of wire, a rod, a rectangular sick, toothpick-like structure, nail-like structure, or any other configuration that provides temporary support of the platform (22) that is easily destabilized by an external force applied to any or most any portion of the animal trap (20). In the illustrated example, the prop (66) is stood between the bottom surface (34) of the platform (22) and the support surface (S), held in place through frictional engagement with both surfaces. In an alternate embodiment (not shown), a wire hinged to a staple on the bottom surface (34) provides a prop which acts as an unstable support. Thus, the prop (66) may be permanently attached to the trap (20) or temporarily engaged.

[0052] Referring to FIGS. 3A, a magnified view of FIG. 2 is provided to more clearly illustrate the operation and components of the present catch release mechanism (30). This figure, as well as and FIG. 4A, illustrates the animal trap (20) in the set or armed configuration, with the prop (66) supporting the second section (38) a distance above the support surface (S) and the first section resting on the support surface (S), forming a lean-to like arrangement. In the illustrated embodiment, the height of the prop (66) is sufficient to permit the sliding member (64) to slide downward within the through hole (70), so that the enlarged head (74) rests on the top surface (32) and the enlarged base (76) is held slightly above the support surface (S). Although, in another embodiment (not illustrated), the enlarged base (76) rests upon the support surface (S), holding the enlarged head (74) slightly above the top surface (32). Arrows (A1, A2) illustrate that the prop (66) is permitted to collapse or fall in any direction if the platform (22) were to be shifted or jarred relative to the support surface (S). The frictional engagement between the prop (66) and the support surface (S) and the platform (22) is easily overcome by movement, vibration, shifting, or other forms of contact between an animal and the trap (20). Arrow (A3) illustrates the up and down axial movement of the sliding member (64) within the through hole (70).

[0053] FIGS. 3B and 4B illustrate the animal trap (20) in the triggered or activated configuration, after an animal has applied a force to the platform (22), the catch (24), the enlarged head (74), the prop (66), or any other portion of the animal trap (20). As discussed above, a sufficient external force applied by the animal will cause the prop to break contact and slide relative to one or both of the support surface (S) and the bottom surface (34). Arrow (A8) illustrates the prop (66) falling down and permitting the platform (22) to drop toward the support surface (S) under the influence of gravity.

[0054] As the platform (22) drops down, the enlarged base (76) of the sliding member (64) contacts the support surface (S), which pushes upwards on the sliding member (64) pushing the sliding member (64) upward and toward the catch (24). Because the enlarged head (74) is positioned beneath the catch (24), upward movement of the sliding member (64) (indicated by arrow (A7)) causes the enlarged head (74) to rotate or otherwise move the catch (24) about the staple (42), as indicated by arrow (A6), to disengage the catch hook (43) from the distal end (58) of the holding arm bar (28), to release the holding arm bar (28) and permit its rotation (as indicated by arrow (A4)) under the spring force of the pivoting kill bar hammer (26) rotating back toward the second section (38) (as indicated by arrow (A9)), thus trapping the animal.

[0055] With the present animal trap (20), the catch may be released in two ways, first, by the traditional manner where the animal torques the catch itself or by simply shifting the platform (22) to knock over the prop (66). The bait (peanut butter, etc.) may be placed on the catch (24), on the enlarged head (74), on the top surface (32), or any portion of the animal trap (20) which would position the animal between the platform (22) and the pivoting kill bar hammer (26) when the trap (20) is activated. Although the sliding member (64) is shown with an enlarged head (74) and enlarged base (76) these are illustrative of just one embodiment, and are not required. An alternate sliding member may include a wire inserted through the through hole (70), with the ends of the wire bent at a ninety degree angle to prevent retraction. The present animal trap (20) provides a substantially increased level of sensitivity and easily activates upon the slightest nudge, even while the animal is merely investigating the bait. Thus, consumption of the bait is not required to activate the trap.

[0056] While particular forms of the present securement system have been illustrated and described, it will also be apparent to those skilled in the art that various modifications can be made without departing from the spirit and scope of the design. Accordingly, it is not intended that the invention be limited except by the claims.
