Description

[Technical field]

[0001] This invention relates to a capture device consisting of two capture rope guides formed in a square frame within a square base case installed on the ground surface, pivoted in an X shape. [Background technology]

[0002] Conventionally, as shown in Figure 7, a pest capture device a is configured such that an installation frame 70 is partially embedded in the ground surface G and the base ends of left and right capture rope guides 71 which are approximately U-shaped are pivoted to the center of the installation frame 70, so that when the footboard is operated, the capture rope guides 71 rise via the biasing springs 72 and the capture ropes capture the legs of the pest.

[0003] Basically, the principle of operation is that the capture rope guide, linked to the step, rises up, causing the capture rope guide to surround the legs of the pest, and then the rope contracts to capture the legs. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-022197 A Summary of the Invention [Problem to be solved by the invention]

[0005] Basically, when the U-shaped capture rope guide linked to the step rises, the capture rope surrounding the semicircular arc part of the U also rises and the ring part of the capture rope surrounds the leg of the pest, and the rope is then pulled and contracted to capture the leg of the pest.Therefore, when the capture rope guide linked to the step rises, the installation frame slides on the ground surface and the capture rope guide also bites into the soil on the ground, and there is a risk that the soil on the ground will interfere as an obstacle and hinder the smooth raising operation of the capture rope guide.

[0006] This invention relates to a pest capture device in which two capture rope guides are assembled in an X-shape and stored inside a square base case which is placed on the ground surface in advance to prevent component parts such as the installation frame and guides from sliding on the ground surface when the capture rope guides are in operation, and the sliding action of the capture rope guides is carried out within the base case. [Means for solving the problem]

[0007] The present invention aims to provide a pest trapping device comprising a base case configured in the shape of a square frame, two capture rope guides assembled and crossed in an X shape that slides along the bottom plate of the base case, a rope guide groove portion for engaging the capture rope formed in the approximately arcuate portion at the tip of the frame of the capture rope guide, an upright biasing spring wrapped around the pivot intersection portion of the capture rope guide so as to urge the rope guides in an upright direction relative to each other, a step on which the X-shaped capture rope guide is spread out approximately horizontally against the bias of the upright biasing spring in preparation for trapping and setting up a pest, and a fixed connecting portion protruding from the end of the step to engage and fix the capture rope guide to the tip of the step, and further characterized in that the fixed connecting portion is configured so that when the pest pushes down on the step, the fixed connecting portion is released to raise the capture rope guide via the upright biasing spring, and the capture rope is pulled up to capture the legs of the pest.

[0008] The fixed connection portion is also characterized in that the upper guide release piece and the lower frame locking piece are configured in an approximately bifurcated shape with a gap between them that is greater than the overlapping thickness of the frame bodies of the two capture rope guides. Effect of the Invention

[0009] According to the invention of claim 1, a base case constructed in a square frame shape, two capture rope guides assembled and crossed in an X shape that slides along the bottom plate of the base case, and two capture rope guides having rope guide groove portions at their ends in the approximately arc-shaped portion of the tip of the frame body formed to engage the capture rope on an arc are pivoted and crossed in an X shape, and an upright biasing spring is wound around the pivotal intersection portion so as to urge the capture rope guides in an upright direction relative to each other, and these structures are placed inside a base case constructed in a square frame shape, so that the two capture rope guides are spread out flat by the step, and when the pest activates the step, the two capture rope guides are displaced into a standing, closed shape by the force of the upright biasing spring, and the capture rope is transformed into a loop-shaped capture shape so that the legs of the pest can be captured from all around.

[0010] Therefore, when the two capture rope guides, which are deployed in a flat state, are triggered by the action of the pest's footboard and displaced into a closed shape around the intersection due to the standing spring force, the sudden spring force causes the two capture rope guides to jump out from within the base case, so that the impact of the capture rope guides' operation is not transmitted to the base case and the base case is not subjected to a load that would inadvertently drag it on the ground.As a result, the capture ropes are detached from the capture rope guides and the binding loop state is formed, allowing for smooth and reliable binding operations.

[0011] In particular, when the vermin pushes down on the step, the fixed connection is released, causing the spring to raise the capture rope guide and pull up the capture rope, thereby providing the effect of reliably capturing the legs of the vermin despite the simple structure.

[0012] According to the invention of claim 2, the fixed connection part is configured to have an upper guide release piece and a lower frame locking piece in a roughly bifurcated shape with a distance equal to the thickness of the overlapping frames of the two capture rope guides, so that the two capture rope guides in the unfolded flat form are stacked and fixed to the end of the tread between the bifurcated guide release piece and the frame locking piece, and preparations for waiting for the vermin are completed. The subsequent action of the vermin pushing down the tread triggers the bifurcated upper guide release piece at the tip of the tread to release its engagement with the capture rope guide, which then rises up via the rising bias spring, pulling up the capture rope and performing a binding operation, making it possible to capture the legs of the vermin.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: Fig. 1 shows an explanatory diagram illustrating an entire pest trapping device A according to the present invention.

[0015] In Figure 1, the base part of the pest trapping device A is provided with a base case 10 configured in a square frame shape, and the base case 10 is provided with a bottom plate 11, on which two capture rope guides 20, 20' are placed in an unfolded state, assembled in an X shape and freely unfoldable via a pivot intersection part 24.

[0016] As shown in Figures 1 to 3, the two capture rope guides 20, 20' are each formed into an approximately square frame shape overall with an approximately arc-shaped tip, and are connected in an X shape by crossing each other in the center via a pivot intersection part 24, with a rope guide groove part 22 for engaging the capture rope formed in the approximately arc-shaped part 21 at the tip of each frame body.

[0017] A looped capture rope R is commonly engaged with the two rope guide grooves 22 for engaging the capture rope, and both ends of the rope R are passed through a rope support 51 consisting of a separately provided one-way mechanism 50, as shown in Figure 8, and the free ends of both ends of the rope are extended to a certain length and fixed to nearby fixed members such as trees.

[0018] Therefore, the harmful animal whose legs are captured by the capture rope R is tied to a tree grove or the like via the capture rope R and is in a captured state.

[0019] The two capture rope guides 20, assembled and crossed in an X shape, are unfolded at the pivot intersection 24 in a flat state, as shown in Figures 4 and 5, and fixed to the tip 30a of the step 30 via a fixed connecting part 31 protruding from the tip 30a of the step 30.

[0020] As shown in Figures 2 and 6, the step 30 is formed to a size that approximately covers the inside of the capture rope guides 20, 20' in their unfolded state, and during the capture preparation stage it approximately covers the inside of the capture rope guides in their unfolded state and is temporarily connected and fixed to the frame of the capture rope guides 20, 20' via a fixed connecting portion 31 protruding from the tip portion 30a of the step 30.

[0021] As shown in Figure 6, both side edges of the step 30 are partially bent downward and positioned to the side of the frame of the capture rope guides 20, 20' to form anti-lateral slippage plates 30'. This prevents the body of the step 30 from slipping to the side when a pest steps on it, causing the capture rope guides 20, 20' to rise up, and prevents the step 30 from interfering with its function as a trigger.

[0022] As shown in Figures 4 and 5, the fixed connection portion 31 is formed into a bifurcated shape by an upper guide release piece 32 and a lower frame engagement piece 33, and is configured into a bifurcated shape with a distance between the two pieces that is slightly larger than or approximately the same as the total overlapping thickness of the capture rope guides 20, 20', and the frame thickness portions of the capture rope guides 20, 20' are clamped together between the two forks.

[0023] One end edge 30a of the step 30 is provisionally connected and fixed to the frame of the approximate arc-shaped tip portion 21 of each of the capture rope guides 20, 20' by the bifurcated fixed connecting portion 31. Note that it is sufficient that the structure of the fixed connecting portion 31 is configured at one end of the step 30, and since the other capture rope guide 20 is pressed and fixed by the other end of the step 30 at the other end of the step 30, a fixed connecting portion 31 of the same structure is not particularly required.

[0024] As shown in Figure 1, the standing biasing spring 40 is a release biasing coil spring, and both free ends are bent outward in an L-shape. By engaging the bent portions 41 with the end edge surfaces 23 of the capture rope guide 20, the two X-shaped intersecting capture rope guides 20 are forcibly biased from an unfolded flat form to a closed standing form.

[0025] In addition, the upright biasing spring 40 may be attached at either one or both of the intersections at the lower ends of each U-shaped capture rope guide 20 which intersect in an X shape.

[0026] In preparation for setting up the trap for pests, the X-shaped trap rope guide 20 is laid out approximately horizontally inside the base case 10 with its inverted U-shaped lower end placed on the bottom plate 11 of the base case 10, and a step 30 is temporarily connected and placed inside the frame of the horizontally laid out trap rope guides 20, 20'.

[0027] In other words, the X-shaped capture rope guide 20 is biased to rise by an upright biasing spring 40 that is engaged with its central pivot intersection 24, so the X-shaped capture rope guide 20 is unfolded in a flat state against this bias and placed inside the base case 10.

[0028] At this time, the fixing connecting portion 31 is used to unfold the capture rope guide 20 from the X-shape to a flat state and place and fix it inside the base case 10.

[0029] As shown in Figure 6, the fixed connecting part 31 is bifurcated with an upper guide release piece 32 and a lower frame locking piece 33 and protrudes from the tip 30a of the tread 30. Therefore, by clamping the two U-shaped capture rope guides 20, 20' in an unfolded, flat state between the bifurcated guide release piece 32 and the frame locking piece 33 of the fixed connecting part 31, the end of the tread 30 is fixed to the capture rope guides 20, 20', and the device is ready to lie in wait for the pest.

[0030] The subsequent downward pushing of the tread 30 by the pest triggers the forked upper guide release piece 32 at the tip of the tread 30 to slide along the engagement surface with the capture rope guides 20, 20' and disengage from the engagement surface of the capture rope guide 20, removing the restriction on the engagement of the tread 30 with the capture rope guides 20, 20', causing the capture rope guides 20, 20' to rise due to the rising bias spring 40, pull up the capture rope R, and securely capture the legs of the pest through a binding action based on the formation of a loop in the capture rope R.
