Utility model registration No. 3180310

However, in the case of the above conventional structure, as an interlocking mechanism that links the opening/closing operation of the locking door body and the tilting movement of the treadle member by the small animal, the locking door body is moved forward and backward by the tilting movement of the treadle member to move the locking door body from the horizontal open state. A connecting rod and a connecting rod guide plate are used for closing the door in a vertically closed state, and the connecting rod and the connecting rod guide plate are made of a so-called rigid body. This has disadvantages in that flexibility in assembling an interlocking mechanism that interlocks the operations of the interlocking mechanism is reduced, and the structure of the interlocking mechanism tends to become complicated.

The present invention aims to solve these inconveniences. Among the present invention, the invention according to claim 1 is characterized in that an entrance portion through which small animals can enter is formed on the front surface of the cage-like main body, and A locking door body whose opening can be opened and closed is provided, and a step plate member that is pressed by a small animal is provided in the cage-like main body so as to be tiltable, and the opening/closing operation of the locking door body and the tilting movement of the foot plate member by the small animal are provided. An interlocking mechanism is provided for interlocking the above, and the interlocking mechanism is provided with a linking wire for linking the step plate member and the locking door body, and a front end of the linking wire is fixed to the locking door body. A magnet that can be magnetically attached to the step plate member is provided at the rear end of the connecting wire, and the connecting wire becomes tensioned due to the magnetic attachment between the step plate member and the magnet, and the locking door body is When the tread plate member is held in the horizontal open state and the magnet separates from the tread member against the magnetic force due to the tilting operation of the tread plate member, the connecting wire becomes relaxed and the locking door body is moved from the horizontal open state to the vertical position. A small animal trap is provided with an opening/closing mechanism that causes the door to close in a closed state, and a closing holding mechanism that prevents or allows the door to open.

Further, the invention according to claim 2 is characterized in that, as the closing holding mechanism, a presser rod is vertically movably disposed on the front surface of the cage-like main body to prevent or allow the opening operation of the closing door body. Further, the invention according to claim 3 is characterized in that, as the opening/closing mechanism, a locking rod portion is disposed on the front surface of the locking door body, and the locking rod portion is connected in a tensioned state.

Since it is configured with an opening/closing mechanism that closes the locking door body from a horizontal open state to a vertically closed state in a relaxed state, the locking door is closed via a connecting wire by the tilting movement of the tread member due to the pressure of a small animal. The body can be reliably closed, and the structure uses a flexible linking wire to link the footboard member and the locking door body, so the linkage mechanism can be simplified and it can be used with cars of various sizes. It is possible to improve the flexibility of assembly into the shaped main body, expand the range of applications, and also has a closing holding mechanism that prevents or allows the opening operation of the locking door body. The door body can be opened and closed reliably.

Further, in the invention as set forth in claim 2, as the closing holding mechanism, a presser rod that can prevent or allow the opening operation of the closing door body is disposed on the front surface of the cage-like main body so as to be movable up and down.

A locking rod portion is disposed on the front surface, and the pulling position of the locking rod portion in the front and back direction in the above-mentioned horizontal open state is freely adjustable, and the connecting wire in a tensioned state is contacted and locked on the locking rod portion. Since the locking door body is provided so that it can be held stationary in the horizontal open state, the opening and closing operations of the locking door body can be performed reliably. Since a guide roller is provided to guide the forward and backward movement of the connecting wire as the door opens and closes, the connecting wire can be guided smoothly, and the tilting operation of the tread plate member and the opening/closing operation of the locking door are prevented. The opening and closing operations of the containment door body can be reliably performed, and small animals can be reliably captured.

A magnet MG that is fixedly connected to the door body 3 and can be magnetically attached to the footboard member 4 is provided at the rear end of the connecting wire 6, and the connecting wire 6 is placed in a tensioned state due to the magnetic attachment between the footboard member 4 and the magnet MG. When the locking door body 3 is held in the horizontal open state 3K, and the magnet MG separates from the footboard member 4 against the magnetic force due to the tilting operation of the footboard member 4, the connecting wire 6 becomes relaxed and the locking door opens. An opening/closing mechanism K for closing the body 3 from a horizontal open state 3K to a vertical closed state 3H is provided, and a closing holding mechanism D capable of preventing or permitting the opening operation of the locking door body 3 is provided.

An extraction door body 8 is provided in the form of a lattice frame made of a plurality of wire rods W that can open and close the portion 7 .

In this case, as shown in FIGS. 2, 3, and 6, the locking door body 3 is formed in a size that allows the entrance portion 2 to be opened and closed, and the upper rod portion 3a of the locking door body 3 is is connected to the opening upper side rod part 2a of the entrance part 2 by a ring-shaped pivot part M, and the locking door body 3 can be freely opened and closed between a horizontal open state 3K and a vertical closed state 3H using the pivot part M as a fulcrum. It is set up and configured.

Further, as the closing holding mechanism D, a presser rod F is vertically movably disposed on the front surface 1d of the cage-like main body 1 to prevent or allow the opening operation of the closing door body 3. In this case, as shown in FIG. As shown in the figure, a pair of left and right guide rods G and G are installed vertically on the front surface 1d of the basket-shaped main body 1 along the left and right sides of the opening of the entrance portion 2, and a presser rod F is placed between the guide rods G and G in a vertically closed state. 3H so as to be vertically movable, and as shown in FIG. With the closing operation to state 3H, the presser rod F between the guide rods G and G is placed in a position where it can move downward from the upper position to the lower position due to its own weight, and the presser rod F, which has moved to the lower position due to its own weight, closes. The entrance part 2 is held closed by pressing the front face of the entry door body 3. In addition, as the above-mentioned closing holding mechanism D, a structure may be adopted in which a tension spring that prevents or allows the opening operation of the locking door body 3 is suspended between the cage-like main body 1 and the locking door body 3. . In the case of this spring structure, the cage-shaped main body 1 and the cage-shaped main body 3 collide with each other due to the instantaneous closing of the containment door body 3, and the impact sound caused by this collision and the vibration of the cage-shaped main body 1 are captured. There is a risk of scaring small animals such as lost cats.

Further, the step plate member 4 is made of a magnetically attachable ferromagnetic material such as metal, and is disposed in the cage-shaped main body 1 so as to be tiltable, and in this case, as shown in FIGS. As shown, the tread member 4 is formed by fixing a tread material 4b to the upper surface of the tread frame 4a, and a plurality of through holes 4c are formed in the front side of the tread member 4, and a plurality of through holes 4c are formed between the through holes 4c and the bottom surface of the cage-like main body 1. 1a is pivotally connected to a fulcrum rod 4d as a wire rod W by a bearing ring 4e. 4f is provided in a protruding manner, and the footboard member 4 is provided so as to be tiltable with the fulcrum rod 4d as the center of tilting S.

Reference numeral 5 denotes an interlocking mechanism, which has a structure for interlocking the opening/closing operation of the locking door body 3 and the tilting operation of the step board member 4 by the small animal Q. In this case, the interlocking mechanism shown in FIGS. As shown, a connecting wire 6 that connects the step plate member 4 and the locking door body 3 to the interlocking mechanism 5 is provided on the cage-shaped main body 1 so as to be movable forward and backward, and the front end of the connecting wire 6 is connected to the above-mentioned. A magnet MG that is fixedly connected to the lower part of the locking door body 3 and can be magnetically attached to the footboard member 4 is provided at the rear end of the connecting wire 6, and the connecting wire 6 is When the locking door body 3 is held in the horizontal opening state 3K in a tense state and the magnet MG separates from the tread plate member 4 against the magnetic force due to the tilting operation of the tread plate member 4, the connecting wire 6 becomes in a relaxed state. The opening/closing mechanism K is provided for closing the locking door body 3 from the horizontal open state 3K to the vertical closed state 3H.

In this case, as shown in FIGS. 2 and 6, a locking rod portion 9 is disposed on the front surface of the locking door body 3 as the opening/closing mechanism K, and the locking rod portion 9 is provided in the front-rear direction in the horizontal opening state 3K. The drawer position (in the vertical direction in the vertically closed state 3H) is freely adjustable, and the tensioned connecting wire 6 contacts and locks the locking rod 9 to move the locking door body 3 into the horizontally opened state 3K. In this case, as shown in FIG. 2, a pair of left and right bearing tubes 3b and 3b are fixed to the front surface of the locking door body 3, and an upper rod 9a and a pair of left and right bearing tubes are fixed to the bearing tubes 3b and 3b. The left and right pair of side rods 9b, 9b of the locking rod portion 9, which also serves as the gate-shaped front handle T, are loosely inserted, and the gate-shaped locking rod portion 9 is inserted. In the horizontal open state 3K of the locking door body 3, the locking door body 3 is inserted so as to be movable in the front and back direction, and the connecting rod 3c is fixed to the lower front side of the locking door body 3 as shown in FIGS. 1 and 2. The front end of the connecting wire 6 is fastened and connected by a fastener 6a, and as shown in FIGS. 1 and 4, a magnet MG that can be magnetically attached to the tread member 4 is fastened to the rear end of the linking wire 6 by a fastener 6b. However, in the vertically closed state 3H of the locking door body 3, as shown in FIGS. 1 and 3, the front end of the connecting wire 6 fixedly connected to the connecting rod 3c is and the presser rod F in the lower position, the forward position of the upper rod 9a of the locking rod part 9 in the lowered state, the forward position of the upper rod part 3a of the locking door body 3, the upper side of the opening of the entrance part 2. Below the connecting wire 6 that is suspended inside the cage-like main body 1 at the rear position of the cage-like main body 1 via the front position of the rod portion 2a and the upper position of the upper face 1c of the cage-like main body 1. A magnet MG that can be magnetically attached to the step plate member 4 is fixed to the end portion by a fastener 6b, and as shown in FIGS. From the front end of the connecting wire 6 fixedly connected to the rod 3c, between the presser rod F and the upper surface of the locking door body 3, the position above the upper side rod portion 3a of the locking door body 3, and the entrance portion. The cage-shaped A magnet MG that can be magnetically attached to the step plate member 4 is fixed to the rear end of the hanging connecting wire 6 by a fastener 6b, which is suspended inside the main body 1 at a rear position.

In this case, as shown in FIGS. 5, 6, and 7, in order to maintain the horizontal open state 3K of the locking door body 3, the presser rod F is moved to the upper position by the guide rods G and G. to allow the upward opening operation of the locking door body 3, and the opening/closing mechanism K causes the locking door body 3 to open upwardly around the pivot portion M to open the entrance portion 2, as shown in FIG. As shown in FIGS. 7 and 8, when the locking door body 3 is in the horizontal open state 3K, the magnet MG at the rear end of the connecting wire 6 is magnetically attached to the footboard member 4, and the locking rod is fixed by the bearing sleeves 3b and 3b. FIG. 6 shows the closing operation of the locking door body 3 using the pivot point M as a fulcrum, which is the center of the opening and closing operation of the locking door body 3, by adjusting the drawing position of the cage-like main body 1 in the front and rear direction of the part 9; At the moment of the clockwise force inside and in the horizontal opening state 3K of the locking door body 3, the connecting wire 6 in the tensioned state comes into contact with the upper rod 9a of the locking rod portion 9 whose pulled-out position has been adjusted. The balance between the moment of the counterclockwise force in FIG. The resulting frictional force between the connecting wire 6 and the upper rod 9a of the locking rod portion 9 holds the locking door body 3 stationary in the horizontal open state 3K.

That is, for example, if the distance from the pivot point M of the locking rod part 9 to the contact position P is too short, the moment of the clockwise force of the closing operation of the locking door body 3 will be too short at the contact position P. The moment becomes larger than the counterclockwise moment due to the force resisting the closing operation, and the upper rod 9a of the locking rod part 9 cannot be pressed and held by the connecting wire 6 in the tensioned state, and the connecting wire 6 is kept in the tensioned state. Therefore, the locking door body 3 cannot be maintained in the horizontal open state 3K. Therefore, depending on the magnitude of the magnetic attraction force between the magnet MG and the tread member 4, the locking rod portion 9 may be loosely inserted into the bearing sleeves 3b, taking into account the above balance, the above drag force, and the above friction force. It is necessary to adjust the position by pulling out the connecting wire 6 to the contact position P where the tension state of the connecting wire 6 can be maintained. Note that when the magnetic force between the magnet MG and the tread member 4 is sufficiently large, the locking door body 3 is moved upward from the horizontal position in the pivot portion M without adjusting the pull-out position of the locking rod portion 9. By further performing the opening operation, the locking door body 3 can be held stationary in the horizontal opening state 3K only by the tension of the connecting wire 6, and the magnet MG separates from the footboard member 4 and the connecting wire 6 is in a relaxed state. When this happens, the closing door body 3 will close from the horizontal open state 3K to the vertical closed state 3H with a snap action operation. In this case, the drawing position of the cage-shaped main body 1 of the locking rod part 9 in the front and back direction can be adjusted freely by the bearing tubes 3b, 3b, but the locking door body 3 is held stationary in the horizontal open state 3K. By fixing the locking rod portion 9 to the locking door body 3 in advance at a position where the drawer can be pulled out, it is also possible to create a configuration in which adjustment of the drawer position is not necessary.

In this case, as shown in FIG. 1, a plurality of guide rollers R, in this case, three guide rollers R, guide the forward and backward movement of the connecting wire 6 as the locking door body 3 opens and closes. It is arranged on the upper surface of the cage-like main body 1.

In addition, in the outlet portion 7 and the outlet door body 8, as shown in FIGS. The guide frame plates 7a, 7a each having a U-shaped planar cross section are fixed in the vertical direction, and the guide frame plates 7a, 7a are made into a plate shape covering the outlet portion 7 in the U-shaped grooves 7b, 7b, and made into a net plate shape using wire rods W. The formed extraction door body 8 is provided to be able to open and close vertically, and a regulating rod 7c is disposed on one guide frame plate 7a so as to be movable forward and backward by a spring 7d, and the regulating rod 7c is pulled against the spring 7d. The regulating rod 7c is pulled out from within the lattice of the wire rod W of the take-out door body 8 to allow vertical opening/closing movement of the take-out door body 8, and when the take-out door body 8 is pulled up and the take-out port 7 is opened, the spring is released. 7d inserts the regulating rod 7c into the lattice of the wire rod W of the extraction door body 8, and the extraction door body 8 is held open in the upper position by locking the wire rod W of the extraction door body 8 and the regulating rod 7c. are doing.

Since this embodiment has the above configuration, as shown in FIGS. 5, 6, and 7, the closing holding mechanism D allows the closing door body 3 to open, and in this case, the presser rod F is moved to the guide rod. G and G move the locking door body 3 from the lower position to the upper position to allow the upward opening operation, and the opening/closing mechanism K causes the locking door body 3 to open upward around the pivot point M. Then, as shown in FIG. 6, FIG. 7, and FIG. In this case, the connecting wire 6 maintains the tensioned state of the cage-like main body 1 of the locking rod portion 9 in the longitudinal direction by the bearing sleeves 3b, 3b, and the horizontal opening state of the locking door body 3. 3K is adjusted to a contact position P where it can be held, and as a result, as shown in FIG. is held in a horizontal open state 3K, and food E, which is a favorite food of small animals Q, is placed inside the cage-like main body 1 at a position behind the footboard member 4, and is on standby in preparation for capture.

In this standby state, as shown in FIG. 5, when a small animal Q enters through the entrance portion 2 and presses the footboard member 4, the footboard member 4 tilts around the tilting center S due to the weight of the small animal Q. As shown in FIG. 12, when the magnet MG separates from the tread plate member 4 against the magnetic force between the magnet MG and the tread plate member 4 due to the tilting of the tread plate member 4, the connecting wire 6 becomes relaxed and the locking door body 3 will perform a closing operation from the horizontal opening state 3K to the vertical closing state 3H, and as the footboard member 4 closes, the presser rod F serving as the closing holding mechanism D is moved from the upper position to the lower position by the guide frames G and G. The presser rod F presses the front surface of the locking door body 3 due to the downward movement of the presser rod F, which causes an unexpected upward opening centering on the pivot point M of the locking door body 3. The small animal Q is trapped inside the cage-like main body 1 and captured. After the capture, the removal door body 8 on the rear surface 1e of the cage-like main body 1 is moved up and opened, and the small animal Q is removed from the exit. It will be taken out from section 7.

Therefore, as an interlocking mechanism 5 that links the opening/closing operation of the locking door body 3 and the tilting movement of the footboard member 4 by the small animal Q, the footboard member 4 and the locking door are connected as shown in FIGS. 1, 4, and 5. A connecting wire 6 that connects the body 3 is provided on the cage-shaped main body 1 so as to be movable forward and backward in the front and rear directions, and the front end of the connecting wire 6 is fixedly connected to the lower part of the locking door body 3. A magnet MG that can be magnetically attached to the tread member 4 is provided at the rear end of the tread plate member 4. Due to the magnetic attachment between the tread plate member 4 and the magnet MG, the connecting wire 6 is put into a tension state, and the locking door body 3 is placed in the horizontal opening state 3K. When the magnet MG separates from the tread plate member 4 against the magnetic force due to the tilting operation of the tread plate member 4, the connecting wire 6 becomes relaxed and the locking door body 3 changes from the horizontal open state 3K to the vertical closed state 3H. Since the opening/closing mechanism K is provided with the opening/closing mechanism K for closing the door, the locking door body 3 can be reliably closed via the connecting wire 6 by the tilting movement of the footboard member 4 due to the pressure of the small animal Q. Since the structure is such that the tread plate member 4 and the locking door body 3 are interlocked using the flexible interlocking wire 6, the interlocking mechanism 5 can be simplified, and it can be incorporated into the cage-shaped main body 1 of various sizes. Since it is equipped with a closing holding mechanism D that can improve performance, expand the range of applications, and prevent or allow the opening operation of the locking door body 3, it is possible to open and close the locking door body 3. The operation can be performed reliably.

In this case, as shown in FIG. 2, as the closing holding mechanism D, a presser rod F is vertically movably arranged on the front surface 1d of the cage-like main body 1 to prevent or allow the opening operation of the closing door body 3. Therefore, the opening operation of the locking door body 3 can be permitted by moving the presser rod F from the lower position to the upper position, and the closing operation of the locking door body 3 can be performed as described above. By moving the presser rod F downward from the upper position to the lower position by its own weight, the opening operation of the locking door body 3 can be prevented, and the opening and closing operation of the locking door body 3 can be performed reliably. In this case, as shown in FIGS. 6 and 7, as the opening/closing mechanism K, a locking rod portion 9 is provided on the front surface of the locking door body 3, and the connecting wire 6 in a tensioned state is attached to the locking rod portion 9. Since the locking door body 3 can be held stationary in the horizontal open state 3K by contacting and locking, the opening and closing operations of the locking door body 3 can be performed reliably. As described above, as the opening/closing mechanism K, a locking rod portion 9 is disposed on the front surface of the locking door body 3, and the drawing position of the locking rod portion 9 in the front and rear direction in the horizontal opening state 3K is arranged so as to be freely adjustable. However, since the connecting wire 6 under tension contacts and locks the locking rod portion 9 so that the locking door body 3 can be held stationary in the horizontal opening state 3K, the opening/closing operation of the locking door body 3 is controlled. It can be done reliably.

Furthermore, in this case, as shown in FIG. 1, a guide roller R is provided to guide the forward and backward movement of the connecting wire 6 as the locking door body 3 opens and closes, so that the connecting wire 6 can be smoothly guided. The tilting operation of the footboard member 4 and the opening/closing operation of the locking door body 3 can be reliably linked, and the opening/closing operation of the locking door body 3 can be performed reliably, and the small animal Q can be reliably removed. can be captured.

Note that the present invention is not limited to the embodiments described above, and includes a presser rod F, a magnet MG, an opening/closing mechanism K, a guide roller R, a closing holding mechanism D, a cage-like main body 1, a tread member 4, an interlocking mechanism 5, The structures of the connecting wire 6, the locking rod portion 9, etc. are designed with appropriate changes.

As described above, the intended purpose can be fully achieved.

In this standby state, as shown in FIG. 5, when a small animal Q enters through the entrance portion 2 and presses the footboard member 4, the footboard member 4 tilts around the tilting center S due to the weight of the small animal Q. As shown in FIG. 12, when the magnet MG separates from the tread plate member 4 against the magnetic force between the magnet MG and the tread plate member 4 due to the tilting of the tread plate member 4, the connecting wire 6 becomes relaxed and the locking door body 3 is closed from the horizontal open state 3K to the vertical closed state 3H, and as the locking door body 3 closes , the presser rod F serving as the closing holding mechanism D is moved downward from the upper position by the guide frames G and G. The presser rod F presses the front surface of the locking door body 3 as the presser rod F moves downward, causing an accidental movement around the pivot point M of the locking door body 3. The upward opening operation is prevented, and the small animal Q is trapped inside the cage-like main body 1 and captured. After the capture, the take-out door body 8 on the rear surface 1e of the cage-like main body 1 is moved upward to open the small animal Q. It will be taken out from the takeout port 7.
