Description

[Detailed description of the invention] [Industrial application field] Although this invention was developed especially for household use, it can also be applied to food and beverage businesses, agriculture and forestry businesses, and is also useful for catching moles. It is.

[Conventional technology]

As is well known, there are two types of mouse traps: an open type and a box type, and with the exception of the open type, the box type only has a single entrance for the mouse.
The closing plate provided at the entrance was also designed to be closed by spring force in conjunction with the bait hook (of wire mesh).

[Problem that the invention attempts to solve]

As mentioned above, in cases where the entrance is only provided at a single location, apart from the habits of the mice, simple calculations show that there is a probability that a mouse will enter the box at multiple locations, for example, two locations. Compared to entering a passage-like box that a mouse can pass through, entering a box that cannot be exited without reversing,
This creates a sense of crisis, and the intrusion rate decreases accordingly.

Furthermore, in relation to hooks for hanging bait, if the closing plate is closed by a spring force, a considerable tensile force must not be applied to the hook.
The spring force may not work (in this case, some of the bait may be eaten and escaped), and with a weak pulling force, the spring force does not work and the bait is often taken. In other words, it was necessary to hang it on a hook under appropriate conditions.

Furthermore, with the box-type bait, it is necessary to insert one's hand into the box to hang the bait from the hook, which requires more effort to hang the bait in the appropriate condition.

[Means and actions for solving problems]

Located between the front and rear fixed bottom plates, the rear part of the movable bottom plate is pivotally supported on the left and right side plates so that the front part can be tilted downward, and a weight is provided on the back side of the rear part of this movable bottom plate, and the front part is A bait nail is provided protruding from the upper surface, and a lower part of a vertically movable operating plate having an upwardly inclined part at the front and back of the upper part is interlockably associated with one side of the front part of the movable bottom plate. A front and rear sliding plate having a downwardly inclined part at one end that abuts against the shaped part by a spring force is provided, and a pin protruding into the box body is fixed to the other end of both sliding plates. A locking piece is provided on the closing plate, which is provided so as to be movable up and down in the front and back, so that the raised position of both closing plates is held by the pin when the downward slanted part is brought into contact with the above-mentioned upward slanted part. A lid plate that can be inserted and removed is provided at the top of the box body, and by pulling up the closing plate, entrances are created at the front and back, which means that the inside of the box body can be passed through, reducing the rate of mouse intrusion. In addition, not only when the mouse bites the bait, but even when the mouse does not bite, it prevents the mouse from getting on the front part of the movable bottom plate.
At the same time as running on the movable bottom plate, the front and rear closing plates are closed at the same time, and this closing is done by its own weight rather than by spring force, and the bait can be set by leaving the lid plate in a half-open or fully open state. It was made possible to do so.

〔Example〕

A is roughly divided into front and rear fixed bottom plates 1, a movable bottom plate 2 provided between the fixed bottom plates 1, 1, left and right side plates 3,
It consists of an inner plate 4 fixed to the inside of either of the left and right side plates 3, a front and rear closing plate 5 that can be moved vertically and inserted/removed, and a cover plate 6 that can be moved back and forth and inserted/removed, and these are made of a desired material, such as synthetic material. A box body made of resin, light metals mainly made of aluminum, wood, etc. is shown.

The front and rear fixed bottom plates 1 are located slightly above the bottom of the left and right side plates 3 (for example, about 1 cm) and are fixed to the left and right side plates 3, and the movable bottom plate 2 is located between the fixed bottom plates 1 and 1, and is fixed to the left and right side plates 3 at the center in the front and back direction. It is provided on the left and right side plates 3 at a location slightly offset from the left and right side plates 3 so as to be able to swing vertically via a shaft 7, and the swinging is controlled by means described later. In addition, a weight 2a is fixed to the back side in the direction in which the shaft 7 is biased as described above (hereinafter referred to as the rear part for convenience), and the weight 2a is fixed to the other side (hereinafter referred to as the front part for convenience) where the weight 7a is not present. A baiting nail 2b is set upright on the surface of the cage.

8 is an actuating plate in which upwardly inclined parts 8a are formed on the left and right sides of the upper part (note, they are formed in the front and back from the box body a); 3a is one of the left and right side plates 3;
That is, it shows a guide groove for the actuating plate bored in the side plate on the side where the inner plate 4 exists, and an actuating plate 8 is fitted into the guide groove 3a so as to be able to move up and down, and a protrusion fixed to the lower part of the actuating plate 8 is shown. A shaft hole provided in the front part of the movable bottom plate 2 is rotatably provided with respect to the shaft 9. (See Fig. 4) 10 and 11 are the actuating plates 8 at opposing ends.
A downwardly inclined portion 10 that comes into contact with an upwardly inclined portion 8a of
a, 11a, which is slidably fitted into a groove 3b bored in the side plate on the side where the guide groove 3a exists, and has an end opposite to the downwardly inclined parts 10a, 11a. The portion is provided with pins 10b and 11b that protrude inward of the box a.

Further, in the groove 3b where the pins 10b and 11b are located, a push spring 12 and a spring receiver 13 for pushing the sliding plates 10 and 11 toward the operating plate 8 are provided. The inner plate 4 is provided to cover one side of the actuating plate 8 and the sliding plate 11, as well as the push spring 12 and the spring receiver 13.
Holes 4a for b and b are provided. (Note: There are holes large enough to allow the pins 10b and 11b to move in the front and back direction. See Figure 2.) The closing plate 5 is provided with vertical grooves 3c provided inside the left and right side plates 3 through the left and right edges. It is movably fitted, and at the lower part of one side inside the closing plate 5,
The locking pieces 5a for the pins 10b and 11b are provided in a protruding manner, and when the closing plate 5 is in the raised position, that is, the front and rear sides of the box body a are open, the locking pieces 5a are attached to the pins 10b and 11b as shown in the imaginary lines in FIGS. The distal end portions are supported by pins 10b and 11b. Further, on the outside of either one of the two closing plates 5 configured as described above,
A knob 5b that can be rotated upward (as described later)
(also used as an eye mark) is provided via a shaft 5c.

The cover plate 6 is fitted in a lateral groove 3d provided in the front-rear direction on the inner upper part of the left and right side plates 3 so as to be movable forward and backward and removable.
The handle 14 has a hole 6a for engaging with the left and right side plates 3 and 4 (see FIG. 1). The handle 14 has a shaft 14a formed at its left and right base that is connected to the bearings 15 attached to the left and right side plates 3.
The left and right shafts 1
When the handle 14 is tilted down, the cover plate 6
The bent portion 14b is formed to fit into the locking hole 6a of the locking plate 6. Reference numeral 16 denotes a reinforcing plate laterally fixed to the left and right side plates 3, and 17 denotes a guide when the closing plate 5 is raised.

Next, if we explain how to use it, we will start with the first and second steps.
As shown in the figure, the handle 14 which has been laid down on the cover plate 6 is raised up, and the bent portion 14b at the end of the shaft portion 14a is detached from the locking hole 6a of the cover plate 6. Next, the lid plate 6 is pulled in either the front or rear direction to make it a half-open state, and after setting the desired bait on the bait nail 2b, the lid plate 6 is closed and the handle 14 is folded back to its original state. In such a case, the bent portion 14 at the shaft portion 14a of the hand 14
b fits into the locking hole 6a of the cover plate 6, and the cover plate 6 becomes immovable. Furthermore, when setting the bait, the movable bottom plate 2 is connected via the bait nail 2b.
A pushing force is applied to the front part of the
Due to this pressing force, the actuating plate 8 is lowered, and the sliding plates 10 and 11 are slid in the direction of the arrow in FIG. 10b moves to the imaginary line and becomes separated from the locking piece 5a of the closing plate 5. (note,
Similarly, if the actuating plate 8 does not lower automatically, press down the pin 11b by placing your fingertip on the movable bottom plate 2. ) In this state, lift the box a and turn it upside down. Then, the closing plate 5 descends toward the cover plate 6 due to its own weight, and the locking piece 5a comes into contact with the cover plate 6 to prevent further descent. Next, push the front part of the movable bottom plate 2 from below the box a, and with the movable bottom plate 2 and the fixed bottom plate 1 level, turn the box a upside down and return it to its original state as shown in Figures 2 and 3. do. In this case, when the movable bottom plate 2 is pressed as described above, the pins 10b and 1 that are on the imaginary line
1b is moved to the solid line position, and the closing plate 5 is lowered until the tip of the locking piece 5a abuts the pins 10b, 11b, and the open state as an entrance for the mouse is maintained. (Note: The lifting position of the operating plate 8 to maintain this open state is determined by the weight 2a provided on the movable bottom plate 2.
The downwardly inclined portions 10a, 10b of the sliding plates 10, 11 based on the spring force of the push springs 12, 12 are held against the upwardly inclined portions 8a, 8a of the actuating plate 8 by pressing resistance. . ) Then, the box a with the front and rear closing parts 5 raised in this manner is installed at a desired location. Now, a mouse has entered the box a from either the front or the front, and a load is applied to the front part of the movable bottom plate 2, or (due to the weight of the mouse) the mouse has bitten the bait, etc. When the horizontal state becomes even slightly oblique, the balance maintained by the weight 2a and the sliding plates 10 and 11 is lost, and as a result, the actuating plate 8 moves from the solid line in FIG. 4 to the imaginary line as shown by the arrow. descend,
At the same time, the sliding plates 10, 11 slide in the direction of the arrow by the spring force of the push springs 12, 12, and the sliding plates 10, 1
The pins 10b, 11b protruding from the front end 1 also move, and the movement of the pins 10b, 11b causes the front and rear closing plates 5, 5 to descend under their own weight.

In addition, the use of the knob 5b attached to either one of the closing plates 5, 5 is to rotate it upward when expelling a captured mouse, so that the mouse can escape from the other closing plate 5. This is for opening when not in use. (Note: Please also refer to the explanation of mole trapping described later.) The present invention can also be used for mole trapping as described above, and in this case, the tilting position of the movable bottom plate 2 and the raising of the closing plate 5 can be changed. In the state where the position is maintained (note), an enclosure is provided under the movable bottom plate 2 to prevent soil from moving, and a guard made of a rigid material is installed to maintain the raised position of the closing plate 5. (by attaching it using the left and right side plates 3, etc.) This is used by setting it in the mole passage or the entrance of the passage, but in this case, the above-mentioned knob rod 5 is used.
The position of box a can be confirmed from above the soil by placing box b slightly protruding above the covered soil.

One embodiment of the present invention has been described above, but
The present invention is not limited to this, and the design may be modified as follows.

() By making the weight 2a movable back and forth, making the spring force of the push spring 12 convertible, or using both functions together, the balance when the movable bottom plate 2 moves from a horizontal state to an inclined state can be improved. The intensity may also be adjustable.

() At the top of the movable bottom plate 2, a small hole for testing is made in the lid plate 6, and a pencil or the like is inserted through the small hole to push the movable bottom plate 2, touch the bait nail 2b, etc. , the degree of adjustment by the above () may be made known. (Note: In this case, it is convenient to configure the cover plate 6 with a transparent plastic plate.) [Effects of the Invention] According to the present invention constructed as described above, the following effects can be achieved.

(i) The mouse intrusion rate can be doubled by simple calculation compared to the conventional method.

(ii) Not only when the mouse bites the bait, but also when the mouse does not bite, that is, when the mouse rides near the front of the movable bottom plate or runs on the movable bottom plate, the front and rear closures are closed. The board is closed. Therefore, the catch rate can be increased accordingly.

(iii) By doing as described in (ii) above, it may be possible to use pseudofeeding containing fragrances that mice like.

(iv) Since the front and rear closing plates are closed at the same time, once a mouse has entered the box, it cannot escape.

(v) Since the closing plate is lowered by its own weight and the inlet is closed without the force of a spring, there is no possibility of the closing plate being eaten away as in the prior art.

(vi) Bait can be attached and taken out with the lid plate half open or fully open, making it easy to attach and take out the bait in a conventional manner.

(vii) If necessary, it can also be used for mole trapping.
