BACKGROUND OF THE INVENTION
The present invention relates to improvements in mouse traps.
[0002]
[Prior art]
  A mouse trap is known from Japanese Utility Model Publication No. 63-31587, for example. This is a figure11As shown in FIG. 5, the mouse inlet 61 is provided in the capture box 60. The inlet 61 is opened and closed by a shutter 63 that can move up and down along the longitudinal groove 62. A tread plate 64 is provided at the bottom of the capture box 60 so as to swing up and down around a horizontal axis 65. A weight 66 for urging the tread plate 64 in a horizontal posture is fixed to a base end of the tread plate 64 behind the horizontal shaft 65, and a feeding nail 67 is erected at a front end of the tread plate 64 in front of the horizontal shaft 65. Further, on the inner surface of one side plate 68 of the capture box 60, a working plate 70 that can move up and down along a vertical guide groove 69, and a pair of left and right slides that can slide in a horizontal direction along a horizontal guide groove 71. The sliding plates 72 and 73 are provided. The operating plate 70 is provided with upward inclined portions 70a and 70b on the left and right sides of the upper end portion thereof, and the lower end portion of the operating plate 70 is pivotally connected to one side of the front end portion of the tread plate 64 via a pivot 74. ing. The sliding plates 72 and 73 are provided with pins 75 for holding the shutter 63 in an open posture at one end, and formed with downward inclined portions 72a and 73a in contact with the upward inclined portions 70a and 70b at the other end. The pressing force is always applied toward the operation plate 70 by 76. The tread plate 64 is held in a horizontal posture by the weight 66 and the left and right sliding plates 72 and 73.
[0003]
Now, by lifting the shutter 63 and engaging the locking piece 77 provided at the lower end of the shutter 63 with the pin 75 of the sliding plate 73, the inlet 61 is opened and this open state is maintained. When a mouse enters from the open entrance 61 and is placed on the tread board 64, the tread board 64 in the horizontal posture is tilted by swinging downward around the horizontal shaft 65 under the load of the mouse. With this inclination, the operating plate 70 is pulled down, and the left and right sliding plates 72 and 73 are slid in the direction of the operating plate 70 by the push springs 76 to move the pin 75 in the same direction. The movement of the pin 75 causes the shutter 63 to descend by its own weight to close the inlet 61, and the mouse is captured in the capture box 60.
[0004]
[Problems to be solved by the invention]
Rats are cautious from the viewpoint of habits, especially parent mice, so that they may vibrate or push the entire capture box 60 before entering the entrance 61. In such a case, the component force of the pressing force of the pressing spring 76 and the sliding plates 72 and 73 acting on the upward inclined portions 70a and 70b of the operating plate 70 is acting downward, and the shutter 63 is closed by its own weight. In the above-described mouse trap, the movement of the capture box 60, particularly the vertical vibration, promotes the lowering of the operating plate 70, and this lowering facilitates the movement of the sliding plates 72 and 73 toward the operating plate 70. As a result, the shutter 63 closes unexpectedly, and there is a risk of losing the opportunity to capture the corner. Further, the type of shutter 63 that closes only by its own weight is likely to be twisted in the longitudinal groove 62, so that it may not be completely closed and may be in a half-open state, and the captured mouse may escape. Furthermore, the captured mouse is submerged in the water together with the capture box 60, and then removed from the capture box 60. At the time of this removal, the dead mouse body can be seen to give an unpleasant feeling and touch the mouse. there were.
[0005]
Therefore, an object of the present invention is to improve the shutter opening holding means in a mouse trap of the type in which the shutter is automatically closed by the mouse load applied to the footboard in the trap box as described above. It is an object of the present invention to provide a mouse trap that has a small capture loss without causing the shutter to close carelessly even if the capture box is shaken a little. An object of the present invention is to provide a trap that can be easily processed without touching the mouse.
[0006]
[Means for Solving the Problems]
As shown in FIG. 1 to FIG. 3, the mouse trap of the present invention includes a capture box 1 having a mouse inlet 9, a shutter 10 that opens and closes the inlet 9, a closing spring 12 that closes and biases the shutter 10, and Inside the capture box 1, a tread plate 22 that is cantilevered so as to be able to swing up and down around a horizontal axis 23 around a horizontal axis 23, and the shutter 10 is engaged with the shutter 10 when the shutter 10 is open. An opening lock member 17 that can rotate about the support shaft 20 in a locked posture in which the shutter 10 is stopped and held in the open position and an unlocked posture in which the shutter 10 is closed when the shutter 10 is closed, and the opening lock member 17 and the tread plate 22 And the opening lock member 17 are urged to the locked posture and are stepped on via the opening lock member 17 and the connection member 24. 22 and a lock structure for a spring 21 for biasing the horizontal position. In addition, the tread plate 22 is set so as to swing and tilt downward about the horizontal axis 23 when the weight of the mouse is added. The connecting member 24 is configured to open and swing downward the tread plate 22 and to convert it into the unlocked posture of the lock member 17.
[0007]
A mouse storage case 27 is further detachably mounted inside or outside the capture box 1. This mouse storage case 27 has an inlet 29 facing the inside of the capture box 1 in a state of being attached to the capture box 1, and this inlet 29 is closed by a closing plate 31 that can be pushed open only from the outside of the inlet 29.
[0008]
[Action]
The shutter 10 is held open by engaging the opening lock member 17 with the shutter 10. When a mouse enters from the entrance 9 and steps on the tread plate 22 with the shutter 10 opened, the tread plate 22 swings downward around the horizontal shaft 23 and tilts due to the tread pressure load. Along with this inclination, the opening lock member 17 is disengaged from the shutter 10 via the connecting member 24 and switched to the unlocked posture. With this unlocking posture, the shutter 10 is automatically closed by the closing spring 12 or its own weight, and the mouse is captured in the capture box 1.
[0009]
Since the opening lock member 17 includes the opening lock spring 21 that is always urged to the locking posture, the shutter 10 can be reliably stopped and held at the opening position. Therefore, even if the capture box 1 is shaken by the mouse, the shutter 10 is not closed carelessly and keeps the capture posture. Since the shutter 10 is reliably closed by the closing biasing force of the closing spring 12 by unlocking the opening lock member 17, the mouse captured in the capture box 1 is not released.
[0010]
The mouse has the habit of desperately trying to escape somewhere when captured in the capture box 1. Therefore, when the mouse storage case 27 with the closing plate 31 is attached to the capture box 1, the mouse captured in the capture box 1 escapes into the mouse storage case 27 and is confined. Thus, the mouse trapped in the storage case 27 can be removed from the capture box 1 together with the storage case 27 without touching it with the hand, so that the mouse after capture can be disposed of easily and quickly together with the mouse storage case 27.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
1 to 3 show a first embodiment of a mouse trap according to the present invention. FIG. 1 is a perspective view showing the mouse with its inlet opened, and FIG. 2 is a longitudinal side view thereof. In each figure, the capture box 1 is composed of a hexahedron of a top plate 2, a bottom plate 3, left and right side plates 4 and 5, a front plate 6 and a rear plate 7, and each of the face plates 2, 3, 4, 5, 6, 7 The material is a single material such as a metal plate, a wire mesh, a plastic plate, a wood plate, paper, cloth, or a combination of two or more of these.
[0012]
The capture box 1 includes a mouse inlet 9 and a shutter 10 that opens and closes the mouse. In the illustrated example, an inlet 9 is provided in the rear half of the top plate 2, and a shutter 10 is provided at the front opening edge of the inlet 9 so as to be rotatable around the shaft 11. The shutter 10 can be rotated around the shaft 11 over a posture in which the inlet 9 is closed (a two-dot chain line state in FIG. 2) and an open posture (a solid line state in FIG. 2) overlapping the upper half of the upper half of the top plate 2. The closing spring 12 wound around the shaft 11 is always urged by the closing spring. A closing lock member 13 made of a leaf spring or the like is installed at the rear opening edge of the inlet 9 of the upper surface plate 2, and a part of the end edge of the shutter 10 on the rotating tip side can be freely engaged with the closing lock member 13. By engaging with the shutter 10, the closed state of the shutter 10 is maintained.
[0013]
An engagement protrusion 15 having a lock hole 14 is provided on the upper surface of the shutter 10 on the rotating front end side. The engaging protrusion 15 enters the opening 16 provided in the front half of the upper surface plate 2 with the opening operation of the shutter 10 and engages with the opening lock member 17 attached to the inner surface side of the front half of the upper surface plate 2. Then, the shutter 10 is opened and locked in the posture. The opening lock member 17 is composed of a swing lever having a hook portion 17a at the tip, and is supported by a support plate 19 fixed to the inner surface side of the top plate 2 so as to swing back and forth around the support shaft 20. The opening lock member 17 always has the hook portion 17a by the pulling action of the opening lock spring 21 by a tension spring or the like hung between the end portion behind the support shaft 20 of the opening lock member 17 and the support plate 19. It is installed to oscillate forward.
[0014]
On the bottom plate 3 inside the capture box 1, a tread plate 22 is arranged to face the lower side of the inlet 9. The tread plate 22 is cantilevered on the bottom plate 3 so as to swing up and down around the horizontal axis 23. The tread plate 22 and the opening lock member 17 are connected by a connecting member 24. The connecting member 24 is an L-shaped connecting rod 25 welded and fixed on the tread plate 22 in an upright state, and a flexible member such as a chain connecting the upper end portion of the connecting rod 25 and the distal end side of the opening lock member 17. 26.
[0015]
The spring pressure of the opening lock spring 21 can maintain the locking posture of the opening locking member 17 and also bring the tread plate 22 into a horizontal posture (solid line state in FIG. 2) through the traction action by the opening locking member 17 and the connecting member 24. Set to hold. And if the weight of 15-40g corresponding to the light weight side weight is applied to the tread board 22 so that not only the rat and the rat with the weight of 200-300g but also the mouse of 15-40g can be captured, the tread board 22 swings downward around the horizontal axis 23 and inclines (in the two-dot chain line state of FIG. 2). With this inclination, the opening lock member 17 opens and locks in the unlocking posture direction through the pulling action of the connecting member 24. It is set so as to swing around the support shaft 20 against the spring force of the spring 21.
[0016]
One or more kinds of bait are scattered and placed in a place other than the top surface of the tread board 22 inside the capture box 1. The reason why the food is not placed on the tread board 22 is that, for example, if an apple is placed on the tread board 22 as food, the apple dries and changes in weight as time passes. This is because an error occurs in the spring pressure setting, and in order to eliminate this, only the weight of the mouse is used.
[0017]
Now, when removing the mouse, when the shutter 10 is opened and the engaging protrusion 15 is inserted into the opening 16, the tip of the engaging protrusion 15 is lowered while coming into contact with the tip of the lock member 17, and this contact action temporarily opens the lock. The member 17 opens and rotates in the unlocking direction against the force of the locking spring 21. By this rotation, when the lock hole 14 of the engagement protrusion 15 just reaches the hook portion 17 a, the hook portion 17 a is fitted into the lock hole 14. By this fitting, the open lock state of the shutter 10 is obtained. This open lock state can be reliably held by the tension action of the open lock spring 21. Therefore, even if the mouse shakes or pushes the capture box 1 with a sense of vigilance, there is no possibility that the shutter 10 closes carelessly.
[0018]
When the mouse enters from the open entrance 9 to eat the food in the capture box 1 and puts a foot on the tread board 22 or gets on the tread board 22, the tread board 22 is swung with the weight of the mouse on the bottom plate 3 It tilts around the horizontal axis 23 until it touches the top. Along with this inclination, the opening lock member 17 receives the traction force of the connecting member 24 and rotates in the unlocking direction, and the hook portion 17 a is detached from the lock hole 14. Then, the shutter 10 is rotated in the closing direction by the spring force of the closing spring 12 to close the inlet 9. In this closing process, a part of the end edge of the shutter 10 on the rotating front end side is engaged with the closing lock member 13 and this closed state is maintained.
[0019]
A mouse storage case 27 is further provided in the capture box 1 so that it can be taken in and out, so that the mouse that has entered the capture box 1 can be confined in the storage case 27 for the convenience of processing. Yes. As shown in FIG. 3, the mouse storage case 27 includes a horizontal cylindrical case body 30 having an inlet 29 opened at one end in the longitudinal direction of the cylinder, and a closing plate 31 provided in the inlet 29. The case body 30 can be formed using an empty can such as a juice can, which can contribute to recycling. In the inlet 29, the closing plate 31 is arranged so as to close the inlet 29 in an inclined posture in which the fixed side end 31 a is high and the free side end 31 b is low, and the fixed side end 31 a is arranged around the shaft 32 with respect to the case body 30. It is pivotally connected so that it can rotate up and down. Accordingly, the mouse can push the closing plate 31 from the outside of the inlet 29 and enter the case body 30. However, once the mouse enters, the closing plate 31 is rotated downward by its own weight and the original inclination is obtained. Because it closes in a posture, the mouse cannot escape. As shown in FIG. 2, the closing plate 31 is provided with a plurality of holes 33 for making it easy to see the bait placed in the case body 30 from the outside of the inlet 29 and discharging the odor of the bait to the outside. ing.
[0020]
This mouse storage case 27 is arranged in a place where the trap box 22 does not hinder the mechanism of the tread board 22 in the capture box 1. In the illustrated example, the mouse storage case 27 is disposed below the opening lock member 17 and between the front plate 6 and the tread plate 22. At that time, an interval is provided between the inlet side end of the mouse storage case 27 and the side plate 5 so that the mouse passes. The mouse trapped in the mouse storage case 27 is discarded together with the mouse storage case 27. In this case, the mouse storage case 27 is taken in and out of the entrance 9 of the capture box 1, or separately, a part 6a of the front plate 6. It is also possible to provide a take-out port 34 in and to take in and out from this take-out port 34.
[0021]
(Second embodiment)
4 to 6 show a second embodiment of the mouse trap according to the present invention. FIG. 4 is a perspective view showing a state in which the mouse entrance is opened, FIG. 5 is an internal plan view, and FIG. 6 is a perspective view of the entrance of the mouse storage case. In this second embodiment, the mouse inlet 9 is provided in the vertical front plate 6 of the capture box 1, the shutter 10 adopts a slide opening / closing type, and in addition, a partial configuration of the connecting member 24, etc. Is different from that of the first embodiment.
[0022]
That is, in the second embodiment, the entrance 9 is provided in the front plate 6 of the capture box 1, and the entrance 9 is opened and closed by the shutter 10. The shutter 10 is slidable in the left-right direction along guide rails 35 and 36 laid parallel to the upper and lower sides inside the front plate 6, and always closes the inlet 9 by a closing spring 12 such as a tension spring. Slide is energized. On the inner surface side of the shutter 10, an engagement protrusion 15 having a semicircular cross section or a shape similar thereto is provided in the vertical direction, and the engagement protrusion 15 is attached to the left end side of the inner surface of the front plate 6. By engaging with the member 17, it is locked in the open posture. The opening lock member 17 is composed of a swing lever having a lock claw 17b at the tip, and is supported by a support plate 19 fixed horizontally on the inner surface side of the front plate 6 so as to be swingable back and forth around the support shaft 20. The opening lock member 17 has the locking claw 17b always moved forward by the spring action of the opening lock spring 21 by a U-shaped leaf spring or the like interposed between the end behind the support shaft 20 and the front plate 6. It is installed so as to be oscillated and biased in the direction of the face plate 6. Both ends of the opening lock spring 21 are integrally connected to the rear end portion of the opening lock member 17 and the inner surface side of the front plate 6 with rivets or the like so as not to be detached from the open lock member 17 and the front plate 6. To.
[0023]
The engagement protrusion 15 is formed in a semicircular cross-sectional shape or a shape similar to this, and the tip of the lock claw 17b of the opening lock member 17 is formed in a rounded shape. The engagement protrusion 15 comes into contact with the tip of the lock claw 17b by fully opening the lock claw 17b. With this contact action, the lock claw 17b is temporarily moved while pushing the opening lock member 17 against the lock spring 21 in the unlocking direction. It smoothly gets over the tip of the lock and engages with the lock claw 17b.
[0024]
On the bottom plate 3 inside the capture box 1, a tread plate 22 is cantilevered so as to swing up and down around a horizontal axis 23. At one end of the horizontal shaft 23 of the tread plate 22, an upright portion 23a constituting a part of the connecting member 24 is integrally bent, and the upright portion 23a and the distal end side of the opening lock member 17 are flexibly formed by a chain or the like. It is connected with the sex member 26. The spring force of the opening lock spring 21 maintains the opening lock posture in which the locking claw 17b of the opening lock member 17 is engaged with the engagement protrusion 15 of the shutter 10 in the open state, and is connected to the opening lock member 17. The tread plate 22 is set so as to be held in a horizontal posture (state shown in FIG. 4) through the pulling action by the member 24. When the weight of the mouse is applied to the tread plate 22, the tread plate 22 swings downward and tilts about the horizontal axis 23, and the opening lock member 17 is connected to the connecting member along with this tilt. It is set to swing around the support shaft 20 against the spring force of the locking spring 21 by opening in the unlocking posture direction through the traction action by 24.
[0025]
Also in this second embodiment, the open state of the shutter 10 is securely held by the action of the opening lock spring 21, so that even if the mouse shakes or pushes the capture box 1, the shutter 10 is inadvertently moved. There is no fear of closing.
When the mouse enters through the open entrance 9 and puts a foot on the tread board 22 or gets on the tread board 22, the tread board 22 inclines due to the load of the rat, and the opening lock member 17 causes the traction force of the connecting member 24 with this inclination. Upon receipt, it rotates in the unlocking direction, and the locking claw 17 b is disengaged from the engaging protrusion 15. Then, the shutter 10 slides in the closing direction by the force of the closing spring 12 to close the inlet 9, and the mouse can be captured in the capture box 1.
[0026]
The capture box 1 allows the upper surface plate 2 to be freely opened and closed, and accommodates the mouse storage case 27 so that it can be inserted and removed along with the opening and closing. In the case of this second embodiment, the mouse storage case 27 is formed in a bottomed cylindrical shape having an inlet 29 that is opened and closed by a separate lid 37, and the mouse that guides the mouse to the inlet 29. The guide tube 39 is arranged side by side in the mouse storage case 27. The mouse guide tube 39 has an inlet 40 at one end and an outlet 41 at one end of the other end, and the outlet 41 is arranged to communicate with the inlet 29 of the mouse storage case 27. A closing plate 42 that can be pushed open only from the outside of the inlet 9 is pivotally connected around the shaft 43 to the inlet 40 of the mouse guide tube 39 in the same manner as shown in FIG. Accordingly, the mouse can enter the guide tube 39 by pushing the closing plate 42 through the inlet 40 of the mouse guide tube 39, but once it enters, the close plate 42 rotates downward due to its own weight. Since the mouse is closed in an inclined posture, the mouse cannot come out, and is guided and captured from the outlet 41 into the mouse storage case 27. The mouse storage case 27 containing the mouse can be taken out of the place and processed by opening the top plate 2 with the lid 37 closed.
[0027]
As described above, when the mouse guide cylinder 39 is installed separately from the mouse storage case 27 and the mouse guide cylinder 39 is provided with a closing plate 42 that can be pushed open only from the outside of the inlet 40, the mouse storage case 27 is closed. It is not necessary to provide the plate 42. Therefore, an empty can such as a juice can can be reused as it is in the storage case 27 with little processing, and the mouse can be processed together with the mouse storage case 27. However, even when using an empty can, the inlet 29 of the mouse storage case 27 has a lid mounting guide 58 having a hole 156 communicating with the inlet 29 as shown in FIG. If the cover 37 is inserted and fixed and the cover 37 can be inserted from the cover insertion slit 57, the cover 37 can be easily closed. The mouse guide tube 39 is formed in a long tunnel shape, and the inlet 40 at one end thereof is positioned inside the capture box 1, while the outlet 41 at the other end is positioned away from the capture box 1. The inlet 29 of the mouse storage case 27 arranged at a location away from the capture box 1 can be communicated with the outlet 41 of the mouse guide tube 39.
[0028]
(Third embodiment)
FIG. 7 shows a third embodiment of the mouse trap according to the present invention. The third embodiment is different from the first and second embodiments in the means for holding the shutter 10 in the open state by the opening lock member 17, and the other configurations are substantially the same. In the third embodiment, an inlet 9 is provided in the upper surface plate 2 of the capture box 1, and a shutter 10 that opens and closes the inlet 9 is provided inside the inlet 9 of the capture box 1 so as to be rotatable around an axis 11. The shutter 10 is always urged to rotate in the closing direction by a closing spring 12 wound on the shaft 11. On one side plate corresponding to the rear side of the shutter 10, an open lock member 17 having a lock claw 17 b at the upper end is supported so as to be swingable back and forth around the support shaft 20.
[0029]
A stopper S for restricting the forward / backward swing angle of the open lock member 17 is disposed on the front side of the open lock member 17. The stopper S has a first stopper S1 that regulates the forward swing angle of the lock claw 17b of the opening lock member 17 and a second stopper S2 that regulates the rear swing angle of the lock claw 17b. I have. The opening lock member 17 has an end portion below the support shaft 20 of the open lock member 17 always rearward by the open lock spring 21 until the upper portion of the support lock 20 of the open lock member 17 contacts the first stopper S1. Has been pulled. The end portion below the support shaft 20 of the opening lock member 17 and the stepping plate 22 on the bottom plate 3 of the capture box 1 are composed of a connecting rod 25 and a flexible member 26 as in the case of the first embodiment. They are connected by a connecting member 24.
[0030]
Thus, prior to the capture of the mouse, when the shutter 10 is pushed downward and rotated against the force of the closing spring 12, the rear end of the arm piece 10a extending rearward from the shaft 11 of the shutter 10 is locked. As soon as the abutment action comes into contact with the lower edge of 17b, the opening lock member 17 once swings the lock claw 17b backward, and as soon as the rear end of the arm piece 10a moves from the lower edge to the upper edge of the lock claw 17b. The open lock spring 21 swings forward until the open lock member 17 contacts the first stopper S1. At the forward swing position of the opening lock member 17, the rear end of the arm piece 10a is supported on the lock claw 17b, and the shutter 10 is held in the open state. At this time, the rear end of the arm piece 10a is pressed against the lock claw 17b by the force of the closing spring 12, so that the opened state of the shutter 10 is reliably maintained.
[0031]
When the mouse rides on the tread plate 22, the lock member 17 opens as the tread plate 22 inclines, receives the pulling force of the connecting member 24, swings the lock claw 17b rearward, and the lock claw 17b comes off the arm piece 10a. . Then, the shutter 10 is rotated in the closing direction by the spring force of the closing spring 12 to close the inlet 9.

The upper wall 57 of the recess 56 is provided with a communication port 58 large enough to allow the mouse to pass through. The communication port 58 communicates the inside of the capture box 1 with the interior of the recess 56. The mouse storage case 27 has an inlet 29 opened at the upper end surface thereof, and the inlet 29 is provided with a closing plate 31 that can be pushed open as in the above embodiment. The mouse storage case 27 is mounted in the recess 56 so that the inlet 29 faces the communication port 58. In this case, it is desirable to fit a cap 59 that can be put on the upper end side having the inlet 29 on the bottom side of the mouse storage case 27. When this is the case, when the mouse is confined in the mouse storage case 27, the cap 59 is removed from the bottom side and covered with the upper end side having the inlet 29, so that the mouse is not inadvertently released. Moreover, fleas and ticks adhering to the mouse can be processed without being transferred.

【The invention's effect】
According to the present invention, the opening lock member 17 of the shutter 10 is provided, and the opening lock member 17 is always urged to the locked posture by the lock spring 21, so that the shutter 10 can be reliably stopped and held at the open position. Therefore, even if the capture box 1 is shaken from the outside by the mouse, the shutter 10 is not inadvertently closed, and the capture posture can be maintained and the capture loss can be reduced. There are advantages. Since the shutter 10 is reliably closed by the closing urging force of the closing spring 12 by unlocking the opening lock member 17, the captured mouse is not released.
Since the mouse storage case 27 is detachably mounted inside or outside the capture box 1, the captured mouse can be processed together with the mouse storage case 27 for convenient handling.
