  A fixed contact 11 and a pivot member 12 are installed on the upper side of the opposite side wall 101 and side wall 102. A movable contact 13 (described later) is mounted on the pivot member 12 so as to be rotatable in the vertical direction (vertical direction).

  The fixed contact 11 is provided on the side opening side. The pivot member 12 is provided on the side wall 103 side opposite to the opening side. Specifically, the pivot member 12 is provided at a position where the lower end side of the movable contact 13 can come into contact with the fixed contact 11 when the mounted movable contact 13 rotates to the fixed contact 11 side. The fixed contact 11 and the pivot member 12 are installed at positions where they are substantially the same height.

  Both the fixed contact 11 and the pivot member 12 are formed of a metal round bar (rod) having a required diameter and capable of being energized. The fixed contact 11 and the pivot member 12 are both provided in a state where the side wall 101 is penetrated and one end side is protruded slightly outward.

  In the present embodiment, the fixed contact 11 is formed of a round bar, but the shape of the fixed contact is not limited. For example, a round cylinder, a square bar, a square cylinder, or a cube is also suitable. Can be used for The pivot member 12 is also required to be able to rotate the movable contact 13, and for example, a round cylindrical shape can be suitably used. Depending on the case, a rectangular bar shape or a rectangular tube shape can also be used.

  In the present embodiment, the fixed contact 11 and the movable contact 13 are provided between the side wall 101 and the side wall 102 opposed to each other. However, this is not limited. For example, the fixed contact 11 and the movable contact 13 are not provided. You may install in the state protruded from the side wall (the side wall 101 or the side wall 102).

  The side wall 103 of the case 10 is provided with an abutting portion 14 that allows a part of the movable contact 13 pivotally supported by the pivot member 12 to abut and stop in a predetermined state (predetermined inclination angle).

  A magnetic body 15 is provided on the back surface side of the bottom portion 100 corresponding to the contact portion 14 and the side wall 103. In this embodiment, the magnetic body 15 is made of metal and is not a magnet. Specifically, a metal linear body extending in the rotating direction of the movable contact 13 was used as the magnetic body 15 (cannot be confirmed in the drawing). However, this is not a limitation. A magnet may be used as long as the movement of the movable contact 13 is not hindered. In the case of a magnet, the material is not particularly limited. For example, a material made of rubber or synthetic resin can be used. Further, the shape is not particularly limited.

  A movable contact 13 is mounted on the pivot member 12 so as to be rotatable in the vertical direction (vertical direction). The movable contact 13 has a vertically long rectangular parallelepiped shape. The movable contact 13 is formed of a metal magnet that can be energized as a whole. The movable contact 13 has N-pole and S-pole magnetic poles on opposite ends.

  On the side surface of the movable contact 13, a mounting portion 130 and a mounting portion 131 that serve as insertion holes for the pivotal support member 12 are formed. The mounting part 130 and the mounting part 131 are configured by through holes formed so as to penetrate the side surfaces. However, the mounting part 130 and the mounting part 131 are not limited to through holes, and may be configured without penetrating. The mounting part 130 and the mounting part 131 are formed closer to the north and south poles so that the movable contact can be rotated by its own weight when the pivot member 12 is passed through either one. That is, the mounting portion 130 and the mounting portion 131 are formed at positions other than the center of gravity of the movable contact and at eccentric positions, respectively.

  The movable contact 13 is mounted so that the other mounting portion 131 is disposed on the lower side through the pivot member 12 through one mounting portion 130. In the present embodiment, the movable contact 13 passes the pivot member 12 through the mounting portion 130, so that the S pole is disposed on the upper end side and the N pole is disposed on the lower end side (see FIG. 1).

  The movable contact 13 is formed of a metal magnet that can be energized as a whole, and the pivot member 12 is formed of a metal round bar that can be energized. Therefore, the movable contact 13 and the pivot member 12 are the pivot member 12. It can be energized while attached to. The metal magnet is a permanent magnet.

The contact operating body 2 moves above the switch device 1 and passes therethrough. In the present embodiment, the contact operating body 2 is arranged such that the upper side is the N pole and the lower side is the S pole (see FIG. 1). The contact operating body 2 may be a magnet as a whole or may be provided with a magnet in part.

(Work)
The operation of the switch device 1 shown in the present embodiment will be described with reference to FIG.
In the normal state, the switch device 1 maintains a state where the fixed contact 11 and the movable contact 13 are not in contact with each other. Specifically, the movable contact 13 cooperates with the magnetic body 15 provided on the contact portion 14 side of the bottom portion 100 to attract the magnetic pole on the lower end side, contacts the contact portion 14, and moves away from the fixed contact 11. It is in a fixed state (see the solid line in FIG. 1). At this time, the switch device 1 is in an open or open circuit state (OFF state).

The movement of the switch device 1 when the contact operating body 2 passes from the left side to the right side in FIG. 1 will be described.
First, the case where the contact operating body 2 moves from the position (i) to the position (ii) will be described.
The movable contact 13 is normally attracted to the magnetic body 15, but since the magnetic body 15 is not a magnet, if the contact operating body 2 having a stronger attracting force than the magnetic body 15 is brought close to the state where the S pole is on the lower side, the movable contact 13 is movable. The contact 13 is released or released from the fixed state attracted to the magnetic body 15, and rotates to the fixed contact 11 side about the pivot member 12 so that the lower N-pole magnetic pole attracts.

  As the movable contact 13 rotates in this way, the surface of the movable contact 13 comes into contact with the fixed contact 11. When the movable contact 13 and the fixed contact 11 come into contact with each other, the switch device 1 is in a connection or closed state (ON state) in which the electric wires C1 and C2 connected to the fixed contact 11 and the pivot member 12 are electrically connected. .

Next, the case where the contact operating body 2 moves from the position (ii) to the position (iii) will be described.
Since the movable contact 13 is mounted on the mounting portion 130 through the pivot member 12 so that the mounting portion 131 is on the lower side, the contact operating body 2 moves away from the position (ii) and the attractive force by the magnetic force is weakened. Thus, the state of falling by its own weight and rotating downward to come into contact with the fixed contact 11 is released. And it returns to the state attracted to the magnetic body 15 again.

  As described above, according to the switch device 1, the movable contact 13 attracts the magnetic body 15 in a normal state, and is in a fixed state in a direction away from the fixed contact 11, for example, even when installed in a slightly inclined state. Thus, unlike the conventional switch device, the movable contact 13 and the fixed contact 11 do not come close to each other. That is, the switch device 1 is less likely to malfunction even when the installation state is bad, and has high reliability.

In the present embodiment, the movable contact 13 is in a fixed state by a force attracting the magnetic body 15, but the case 10 itself has a magnetic action that performs the same action as the magnetic body 15 so that it can be fixed. May be.
Further, in the present embodiment, the movable contact 13 is in a fixed state by a force attracting the magnetic body 15, but this is not limited. For example, if a magnet is included in the magnetic body 15, the magnetic force is reduced. A fixed state can also be obtained by utilizing the action of the force of contact.

  In the present embodiment, the contact operating body 2 sets the direction of the magnetic pole so that the upper side is the N pole and the lower side is the S pole, but this is not a limitation. For example, the movable contact 13 may be attached to the mounting portion 131 through the pivot member 12 so that the magnetic poles are upside down so that the upper side of the contact operating body 2 becomes the S pole and the lower side becomes the N pole. .

  In the present embodiment, the movable contact 13 is entirely formed of a metal magnet. However, this is not a limitation, and the movable contact 13 can be energized at least at a portion in contact with the fixed contact 11. good. Further, the movable contact 13 does not have to be a magnet as a whole, and only needs to have a magnet in part so that the movable contact 13 can be rotated when the contact operating body 2 approaches. For example, a material made of rubber or synthetic resin can also be used. Furthermore, it is sufficient that the fixed contact can be energized at least at the portion that contacts the movable contact.

(Work)
With reference to FIG. 1 thru | or FIG. 3, the effect | action of the door apparatus T for pets shown in this Embodiment is demonstrated.
First, the case where the pet P including the contact operating body 2 passes through the wall burying member 5 from the outdoor side and approaches the switch device 1 will be described.
When the pet P approaches from the outdoor side, the movable contact 13 of the switch device 1 operates from a state where it is attracted to the magnetic body 15. The movable contact 13 rotates toward the fixed contact 11 around the pivot member 12 so that the lower N-pole magnetic pole attracts the lower S-pole of the contact operating body 2 as described above. In this way, the movable contact 13 and the fixed contact 11 come into contact with each other, and the switch device 1 enters a connection or closed state (ON state) in which the movable contact 13 and the fixed contact 11 are electrically connected.

  When the movable contact 13 and the fixed contact 11 are electrically connected, electricity is supplied from the battery B to the motor 80 and the like by the control device. Thereby, the rotating shaft 81 rotates and the string 83 is wound up. When the string 83 is wound up, the plate 70 that has closed the passage portion 32 is pulled up along the guide member 71, and the passage portion 32 is allowed to pass.

  Since the control device uses a device having a timer function for releasing the energized state after a lapse of a predetermined time, the passage unit 32 is maintained in a state where it can pass for a predetermined time. Therefore, the pet P passes the passage part 32 during this time and enters the indoor side. In this embodiment, electricity is supplied from the battery B, but this is not a limitation. For example, a power cord may be provided and supplied from an outlet.

  When a predetermined time (for example, about 5 seconds) elapses when the passage portion 32 is allowed to pass, the energized state is released by the control device, and the plate body 70 is lowered by its own weight. The plate 70 is set to descend slowly. Thus, the passage part 32 is closed again.

Next, a case where the pet P approaches the pet animal door device T from the indoor side will be described.
When the pet P approaches from the indoor side and is placed on the indoor side switch device 9, the step member 91 constituting the indoor side switch device 9 is slightly lowered by the weight of the pet P. When the step member 91 is lowered, the lift button 902 of the micro switch 901 is pushed on the back surface of the step member 91.

  When the up / down button 902 is pressed, electricity is supplied from the battery B to the motor 80 and the like by the control device. As a result, the plate body 70 is pulled up and the passage portion 32 can pass. Also in this case, the passage part 32 is maintained in a state where it can pass for a predetermined time. Accordingly, the pet P moves from the indoor side to the outdoor side through the passage portion 32 during this period.

  That is, the pet P provided with the contact operating body 2 can freely enter and exit indoors and outdoors through the pet animal door device T. In addition, since the coil spring 92 is contracted and the urging | biasing force is acting because the tread member 91 falls, if the state in which the pet P was mounted is cancelled | released, it will return to an original state. Also. Similarly, the up / down button 902 of the micro switch 901 returns from the pressed state to the original state.

  According to the door device T for pet animals, even if an animal that is not a pet P approaches the door member 7 from the outdoor side, the plate body 70 is normally closed, and the contact operating body 2 is not provided. 1 does not work. Therefore, an animal that is not a pet P cannot pass through the door member 7 and cannot enter the room.

  On the other hand, from the indoor side to the outdoor side, if the step member 91 is lowered and the elevating button 902 of the micro switch 901 is pushed, the plate body 70 is pulled up and the passage part 32 can pass. You can pass through.

  By the way, if the pet animal door device T becomes widespread, for example, the same pet animal door device T is attached to a neighbor's house, and a contact manipulator 2 is provided to a pet of another person. A situation may occur in which the magnetic pole directions of the contact operating body 2 and the movable contact 13 are set to be the same. In this case, it is possible to enter another person's pet by passing through his / her pet animal door device T.

  In the pet animal door device T, since the mounting portion 130 and the mounting portion 131 are provided on the movable contact 13, when the pivot member 12 is passed through the mounting portion 130, the pivot member 12 is attached to the mounting portion 131. If the movable contact 13 is attached so that the magnetic poles are turned upside down, and the magnetic pole of the contact operating body 2 is also changed so that the upper side is the S pole and the lower side is the N pole, your pet P can pass through, You can prevent other people's pets from passing.

  In this embodiment, the pet animal door device T is provided with a micro switch 901 in the indoor side switch device 9 so that it can pass from the indoor side to the outdoor side without being a pet P. However, this is not a limitation. For example, if the switch device 1 is also provided in the indoor side switch device 9, only the pet P provided with the contact operating body 2 can pass from the indoor side to the outdoor side (see FIG. 4).

FIG. 4 is a cross-sectional explanatory view showing another embodiment of the door device for pet animals.
A switch device 1 is provided in the indoor switch device 9 shown in FIG. The switch device 1 is fixed so that the fixed contact 11 faces the indoor side.
