Description

  The present invention relates to a mouse removing device that captures mice that frequently appear in each home or town.

2. Description of the Related Art Conventionally, as a device for capturing small animals such as mice that appear in each house or town, a spring type mouse catcher and a cage type mouse catcher are known. In the spring type, a rat is sandwiched by applying energy accumulated by a spring to a sandwiching member provided on a substrate and utilizing the rotational force of the sandwiching member. That is, when the energy is accumulated in the spring, the pinching member is locked against the spring energy, and when the rat bites into the bait attached to the pinching member, the pinching member is unlocked and the spring The accumulated energy is converted into the rotational force of the pinching member, and the mouse is pinched and captured by the substrate.
In addition, the cage type has a configuration in which the entrance of the cage is easy to enter and it is difficult to get out, and the rat is captured. There is a problem that the effect of the spring-type mousetrap is not demonstrated unless you eat the food. The cage-type mouse trap has an inconvenience that the mouse instinctively senses danger and does not enter.

  In addition, it is known that when a bait is wound on an adhesive sheet and a mouse is attached to the bait and placed on the adhesive sheet, a foot or a body cannot be attached to the adhesive sheet. However, since the adhesive force of the floor-mounted adhesive sheet is weakened when the feet of the mouse are wet or dirty, an adhesive-type mouse trapping tool that improves this has been proposed (see, for example, Patent Document 1). ).

As shown in FIG. 4, the mousetrap described in Patent Document 1 is configured such that a lower plate 100 with a hooked rod 101 is inclined like a seesaw, and a bait 102 is scattered thereon. . And the upper board 104 which apply | coated the adhesive 103 on the upper side is suspended with the thread | yarn 105. The thread 105 is connected to a rod 106, and the rod 106 is pulled by the hook-shaped rod 101 in the left direction of the drawing, and the upper plate 104 coated with an adhesive is held in a lifted state.
In this mouse catching tool, when the mouse 107 enters the lower plate 100 from the left and advances to the back, and reaches the portion of the bait 102, the seesaw lower plate 100 opposes the fulcrum 108 as an axis by the weight of the mouse 107. The hooks 101 and 106 are disengaged, and the upper plate 104 coated with adhesive drops. As a result, the mouse 107 is sandwiched and captured between the adhesive application plate 104 and the lower plate 100.
JP 2002-272350 A

  However, in the invention described in Patent Document 1, since the lower plate 100 is disposed obliquely with respect to the ground and rotates around the fulcrum 108 as a central axis, the lower plate 100 is easy to move and becomes unstable. The mouse 107 generally has a very cautious behavior, and there is a possibility that the mouse 107 may not enter with a warning that the lower plate 100 is in a moving state. In addition, a large-scale mechanism for lifting the adhesive application plate 104 is required, and there is a problem that the apparatus itself becomes complicated.

  In order to solve the above-mentioned problems of the prior art, an object of the present invention is to provide a mouse trap that can reliably capture a mouse with a very simple structure without causing the mouse to be wary. is there.

  In order to solve the above-described problems and achieve the object of the present invention, the mouse trap of the present invention is configured by opening the opposing surface of the back plate from the bottom plate, the pair of left and right side plates, the top plate, and the back plate. The upper plate is provided with a hole at a predetermined position, and is provided with a door that opens and closes by opening and closing the opening surface facing the back plate, and a thread is coupled to the door. Guided by a first support bar disposed above the surface, is connected to the first work-in bar through the hole in the upper plate, and the left and right side plates are provided at predetermined positions parallel to the bottom plate and the back plate. The second support rod is coupled to the housing, and a second work rod is provided in the housing to act in cooperation with the first work rod. A support member for holding the work-in-progress bar by the first work-in bar is formed, and the first work-in bar, the second support bar, and the tension of the thread The second widget bar, pressing members supported in a state where the bottom plate a predetermined distance, by substantially held parallel to the bottom plate, in which to wait a rat invasion door as part opening state.

  The mouse catcher of the present invention includes a bottom plate, a pair of left and right side plates coupled to the bottom plate, a top plate coupled to the side plate and the bottom plate and having holes formed at predetermined positions, and the bottom plate and the left and right side plates. And a back plate that is coupled to the upper plate and forms a housing by opening a facing surface, a door that controls opening and closing of the opening surface facing the back plate, and for moving the door up and down, the left and right side plates A pair of left and right columns and guides provided at the end of the opening surface side, a first support bar fixed at or near the upper end of the pair of left and right columns and guides, and a predetermined position on the left and right side plates A second support rod fixedly disposed substantially parallel to both the bottom plate and the back plate, a pair of left and right support members provided on the left and right side plates, a thread having one end connected to the upper portion of the door, and controlling the opening and closing of the door; A first work-in bar to which the other end of the thread via the hole in the upper plate is connected and fixed, and the left and right sides Is characterized by being obtained is composed of a second widget rod secured pressed against the supporting member provided on. The second work-in bar is pressed against the support member provided on the left and right side plates by the second support bar, the yarn tension, and the cooperative action of the first work-in bar, and a position away from the bottom plate by a predetermined distance. Is held substantially parallel to the bottom plate.

According to the mouse trap of the present invention, the door is opened by thread, the first work rod, the support member, and the second work rod so that the mouse to be captured can enter the housing. When a mouse that has been pulled up and enters the box from the opened door steps on the second work rod and drops the second work rod onto the bottom plate, the first work rod rotates and the door is self-weighted. The mouse is captured by dropping and closing.
As a preferred form of the present invention, a weight is added to the door to make it easier to drop.

  According to the mouse trap of the present invention, since the entrance is wide open, the mouse is caught in the bait placed in the back and enters the enclosure from the entrance that opens without warning. Since it almost certainly steps on a work-in-progress bar placed sideways, the entrance is shut off at that moment, and mice can be easily captured.

Hereinafter, based on FIGS. 1-3, the example of one Embodiment of the mouse | mouth trap of this invention is demonstrated.
FIG. 1 is a perspective view showing the entire structure of a mouse trap of the present invention, and FIGS. 2 and 3 are elevation sectional views for explaining the opening and closing operation of the door.

  As shown in FIG. 1, the mouse catcher of the present invention is such that the surface facing the back plate 3 is opened by the bottom plate 1, the left and right side plates 2 </ b> A and 2 </ b> B, the back plate 3, and the top plate 4. A housing is formed. In the vicinity of the opening surfaces of the left and right side plates 2A and 2B, support columns 13A and 13B serving as support columns and guide guides are provided, and doors that cover the openings through guide grooves formed by the support columns 13A and 13B and guide members 14A and 14B. 5 is formed to be slidable. A hook hook 15 is provided on the upper portion of the door 5, and one end of a thread 16 for pulling the door 5 is connected to the hook hook 15. The thread 16 for pulling the door 5 is connected to the upper part of the first work bar 8 through the first support bar 6 fixed to the upper part of the columns 13A and 13B and the hole 17 provided in the upper plate 4. ing.

  A second support bar 7 is fixed to the left and right side plates 2A and 2B substantially parallel to the bottom plate 1. Similarly, support members 10A and 10B are provided at the portions of the left and right side plates 2A and 2B close to the bottom plate 1, as shown in FIG. 1, and the second pulling force of the thread 16 is pulled by the second pulling force. The work-in bar 9 is fixed by being pressed against the supporting members 10A and 10B.

  Further, the door 5 that opens and closes the opening surface is preferably made of a heavy material, but even if it is made of light wood, the door is made heavy by attaching the weight 11 to the front surface of the door. It is devised to. If the second work-in bar B (9) is set up about 1 to 2 cm away from the floor (the surface of the bottom plate 1), there is a high possibility that a mouse will enter and step on. However, the height at which the second work-in bar B (9) is installed may be determined in consideration of the size of the mouse to be captured, and may be either the practice shown in FIG. 1 or the position of the dotted line.

Further, in this example, as a guide member for moving the open / close door 5 up and down, a guide guide composed of support columns 13A and 13B and guide members 14A and 14B is provided in front of the left and right side plates 2A and 2B. Instead of this, rail-like protrusions may be provided on the left and right side plates 2A and 2B, and grooves may be provided on the open / close door 5 side corresponding to the rails. Further, the size and shape of the hole 17 provided in the upper plate 4 are arbitrary, and may be any size and shape through which the thread 16 can easily penetrate.
The mouse trap prototyped by the present inventor (applicant) has a depth of 30 cm, a height of 30 cm, and a width of 20 cm. The first support bar 6 and the second support bar 7 are formed by round bars having a diameter of about 10 mm, and the first work bar 8 and the second work bar 9 are formed by thin bars of about 5 mm. . This dimension may be an arbitrary size and can be appropriately changed according to the size of the mouse to be captured.

Next, based on FIG.2 and FIG.3, operation | movement of one embodiment of this invention is demonstrated.
First, as shown in FIG. 2, the bait 12 is placed in the back part of the bottom plate 1, the door 5 is fully lifted while pulling the thread by hand, and the second work rod 9 is moved beyond the first work rod 8. Press and fix the supporting members 10A and 10B. At this time, the other end of the first work-in bar 8 is pressed against the second support bar 7. In this state, the hand is taken out of the housing, and when the thread is released, the door 5 moves downward due to its gravity and is suspended in the state shown in the figure.

Based on FIG. 2, how the first work bar 8 and the second work bar 9 act against the gravity of the door 5 will be described. When the mass of the door 5 is M, force F (= Mg weight) acts downward. This force F is transmitted to the first work bar 8 via the first support bar 6, the hole 17, and the second support bar B7, and the first work bar 8 receives the drag force F1 from the second support bar 7. And the sum of the drag F2 from the second work-in bar 9 is balanced. That is, the relational expression F = F1 + F2 holds.
As a result, the second work rod 9 is pressed against the support members 10A and 10B, and a frictional force against the gravity of the second work rod 9 acts between the support members 10A and 10B. It is arranged in a space floating about 1 cm from the surface of the bottom plate 1.

  In this state, the door 5 is lifted several centimeters upward, and an opening necessary for the rat to enter is generated. When the mouse tries to eat the bait 12 and enters the enclosure and crosses the second work-in rod 9, the foot or body touches the second work-in rod 9 and drops it onto the bottom plate 1. Then, since the force F2 in FIG. 2 does not act, the first work rod 8 is pulled by the gravity F of the door (same as the tension of the thread 16), and the door 5 falls by gravity (see FIG. 3). That is, as shown in FIG. 3, when the mouse is stepped on, the second work rod 9 falls in the direction of the arrow, so that the tension of the thread 14 is released, the door 5 falls by its gravity, the entrance is closed, and the mouse is closed. Is captured.

Although the present invention has been described as a mouse trap, the principle of the present invention can be applied freely by changing the size of the rod or the work rod even when capturing animals or birds other than rats. It is.
Further, the present invention is not limited to the one embodiment described here, but includes various embodiments without departing from the gist of the present invention described in the claims. Not too long.

It is a perspective view of the mouse remover of the present invention. It is sectional drawing for demonstrating the state before the mouse | mouth capture | acquisition of the mouse | mouth trap of this invention. It is sectional drawing for demonstrating the state after the mouse | mouth capture | acquisition of the mouse | mouth trap of this invention. It is a figure for demonstrating the example of the conventional mouse | mouth catcher.
