The present invention relates to an improvement in a mouse trap.

[0002]

2. Description of the Related Art A mouse trap is described in, for example,
It is known from JP 31587. As shown in FIG. 12, a trap box 60 is provided with a mouse entrance 61. The entrance 61 is opened and closed by a shutter 63 that can move up and down along a vertical groove 62. At the bottom of the capture box 60, a tread 6
4 is provided so as to be swingable up and down around a horizontal axis 65. A weight 66 for urging the tread plate 64 to a horizontal position is fixed to a base end of the tread plate 64 behind the horizontal shaft 65, and a bait nail 67 is erected at a front end of the tread plate 64 in front of the horizontal shaft 65. On the inner surface of one side plate 68 of the capture box 60, an operation plate 70 which can move up and down along a vertical guide groove 69, and a left and right lateral guide groove 71
A pair of left and right sliding plates 72 slidable in the left and right and lateral directions along
73 is deployed. The operating plate 70 is provided with upwardly inclined portions 70a and 70b on the left and right of the upper end thereof.
Is pivotally connected to one end of a step plate 64 via a pivot 74. The sliding plates 72 and 73 are
One end is provided with a pin 75 for holding the shutter 63 in an open position, and the other end is formed with downwardly inclined portions 72a and 73a that abut against the upwardly inclined portions 70a and 70b. The pressing force is applied. The tread plate 64 includes a weight 66 and left and right sliding plates 72 and 73.
And is held in a horizontal position.

[0003] Now, the shutter 63 is lifted, and the locking piece 77 provided at the lower end of the shutter 63 is engaged with the pin 75 of the sliding plate 73, thereby opening the entrance 61 and maintaining this open state. When the mouse enters from the entrance 61 in the open state and is placed on the tread plate 64, the tread plate 64 in the horizontal posture swings downward around the horizontal axis 65 by the weight of the mouse and tilts.
With this inclination, the operating plate 70 is pulled down, and the left and right sliding plates 72 and 73 are slid toward the operating plate 70 by the pressing springs 76 to move the pins 75 in the same direction. By the movement of the pin 75, the shutter 63 descends by its own weight, closing the entrance 61,
The mouse is captured in the capture box 60.

[0004]

Since the mouse is cautious in habits, and especially the close mouse is alert, the entire catch box 60 may be shaken or pushed before entering the entrance 61. In such a case, the upwardly inclined portion 70 of the operation plate 70
a spring 70 and a sliding plate 72.7 acting on a.70b
In the above-described mouse trap in which the component force of the pressing force of No. 3 acts downward and the shutter 63 is closed by its own weight, the movement of the trapping box 60, particularly the vertical vibration, promotes the lowering of the operation plate 70. As a result, the sliding plates 72 and 73 are easily moved in the direction of the operation plate 70 due to this descent,
With this movement, the shutter 63 closes unexpectedly,
There is a risk of losing the chance of catching. Further, in the shutter 63 of the type which is closed only by its own weight, since the torsion easily occurs in the vertical groove 62, the shutter 63 may not be completely closed and may be in a half-open state, so that there is a problem that the captured mouse escapes. Further, the captured mouse is sunk in the water together with the capture box 60 and killed.
At the time of taking out the mouse, the dead mouse body was seen at this time, giving discomfort and possibly touching the mouse.

Accordingly, an object of the present invention is to provide an improvement in the means for holding the opening of the shutter in a mouse catcher of the type in which the shutter is automatically closed by the load of the mouse applied to the tread plate in the capture box. Accordingly, an object of the present invention is to provide a mouse trap with a small capture loss, in which the shutter is not inadvertently closed even when the capture box is slightly shaken. SUMMARY OF THE INVENTION An object of the present invention is to provide a catcher which can easily handle a trapped mouse without touching it.

Since the mouse confined in the storage case 27 can be removed from the capture box 1 together with the storage case 27 without touching the mouse, the mouse after capture can be easily and quickly disposed of together with the mouse storage case 27.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIGS. 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 entrance opened, and FIG. 2 is a longitudinal side view thereof. In each of the figures, the capture box 1 is a top plate 2,
It consists of a hexahedron of a bottom plate 3, left and right side plates 4,5, a front plate 6, and a rear plate 7, and the material of each of the face plates 2,3,4,5,6.7 is a metal plate, a wire mesh, a plastic plate, a wooden plate, A single material such as paper or cloth, or a combination of two or more of these materials.

The capture box 1 is provided with a mouse entrance 9 and a shutter 10 for opening and closing the entrance. In the illustrated example, an entrance 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 entrance 9 so as to be rotatable back and forth about an axis 11. The shutter 10 is rotatable around the shaft 11 in a posture for closing the entrance 9 (in a two-dot chain line state in FIG. 2) and an open posture in which the shutter 9 overlaps the upper part of the front half of the upper surface plate 2 (in a solid line state for FIG. 2). , Is always urged to close by a closing spring 12 wound on the shaft 11. At the rear opening edge of the entrance 9 of the upper plate 2, a closing lock member 13 such as a leaf spring is installed.
The closed state of the shutter 10 is maintained by engaging and disengaging a part of the edge on the rotation leading end side of the shutter 10.

[0013] On the upper surface of the shutter 10 on the rotation tip side,
An engagement projection 15 having a lock hole 14 is provided.
The engaging projection 15 enters an opening 16 provided in the front half of the upper surface plate 2 with the opening operation of the shutter 10, and engages with an 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 swinging lever having a hook portion 17 a at a tip thereof, and is supported by a support plate 19 fixed to the inner surface side of the upper surface plate 2 so as to be able to swing back and forth around the support shaft 20. The opening lock member 17 is configured such that the hook portion 17a is always urged by a tension action of the opening lock spring 21 by a tension spring or the like hung between an end portion of the opening lock member 17 behind the support shaft 20 and the support plate 19. It is installed to swing forward.

On the bottom plate 3 inside the capture box 1, a tread plate 22 is provided so as to face below the entrance 9. The tread plate 22 is cantilevered on the bottom plate 3 so as to swing up and down around a 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 upright on the tread plate 22, and a flexible member such as a chain connecting the upper end of the connecting rod 25 and the distal end of the opening lock member 17. 26.

The spring pressure of the opening lock spring 21 can maintain the locking posture of the opening lock member 17 and
The step plate 22 is set so as to be held in a horizontal posture (solid line state in FIG. 2) through the traction action of the opening lock member 17 and the connecting member 24. Then, when a weight of 15 to 40 g corresponding to the weight on the light side is applied to the tread plate 22 so as to capture not only a rat and a rat with a weight of 200 to 300 g but also a mouse with a weight of 15 to 40 g,
The tread plate 22 swings downward about the horizontal axis 23 and tilts (in a two-dot chain line state in FIG. 2). With this tilt, the opening lock member 17 opens in the unlocking posture direction through the traction action of the connecting member 24 and locks. It is set to swing around the support shaft 20 against the spring force of the use spring 21.

One or more kinds of bait are sowed and placed on a portion other than the upper surface of the tread plate 22 inside the capture box 1. The reason why the bait is not placed on the tread plate 22 is that, for example, when the apple is placed on the tread plate 22 as bait, the apple dries and loses weight as the date and time passes. This is because the setting of the spring pressure is incorrect, and in order to solve this, only the weight of the mouse is used.

Now, when removing the mouse, the shutter 10
When the opening is opened and the engaging projection 15 is inserted into the opening 16, the tip of the engaging projection 15 opens and descends while abutting on the tip of the lock member 17.
Opens and rotates in the unlocking direction against the force of the locking spring 21. By this rotation, the lock hole 1 of the engagement protrusion 15 is formed.
When the hook 4 reaches the hook 17a, the hook 17a fits into the lock hole 14. By this fitting, an open locked state of the shutter 10 is obtained. This open lock state can be reliably held by the pulling action of the open lock spring 21. Therefore, even if the mouse shakes or pushes the capture box 1 with a sense of caution, there is no possibility that the shutter 10 will be inadvertently closed.

When the mouse enters from the open entrance 9 to eat the food in the capture box 1 and puts or rides on the tread plate 22, the tread plate 22 swings with the weight of the mouse to swing the tip end side. It is inclined around the horizontal axis 23 until it comes into contact with the bottom plate 3. With this inclination, the opening lock member 17 rotates in the unlocking direction by receiving the traction force of the connecting member 24, and the hook portion 17 a comes off the lock hole 14. Then, the shutter 10 rotates in the closing direction by the spring force of the closing spring 12 to close the entrance 9. In this closing process, shutter 1
A part of the edge on the rotation front end side of the engagement portion 0 is engaged with the closing lock member 13, and the closed state is maintained.

A mouse storage case 27 is further provided inside the capture box 1 so as to be able to be taken in and out.
The mouse that has entered the inside can be confined in the storage case 27 to facilitate processing.
