Description

[Detailed explanation of the invention] This is an invention that automatically hooks the door when a pet animal such as a dog or cat exits and closes the door, and makes it easy to check whether the hook is in the locked position.

To explain the embodiment shown in the drawings, reference numeral 1 is a box body, and one side of a door 2 consisting of vertical and horizontal bars is hinged to the open front part, and stoppers 3, 3 are protruded from the top and bottom of the other side.

4.4 is a guide tube formed by lubricating a metal plate in a U shape, and is fixed to the front side of the box 1 by standing upright on both sides of the tube, and is fixed to the center of the front surface. A ■-shaped notch 5 is provided.

Reference numeral 6 denotes a hooking plate made of wire metal that is inserted into the upper and lower guide tubes 4, 4 so as to be able to rise and fall freely, and is provided with a downwardly inclined surface 7 that guides the locking rod 3, looking into the ■-shaped notch 5, and a slightly upwardly facing surface 7 on the inside thereof. A recess 8 for retention is provided.

If these are all made of stainless steel, they can be washed with water and kept clean.

In this device, when the door 2 is closed, the upper and lower stoppers 3 move to the second position.
At the position indicated by the dotted line in the figure, it comes into contact with the downwardly inclined surface 7 extending into the ■-shaped notch 5 of the guiding tube 4, pushes up the hook plate 6, and when it reaches the inside thereof, the hook plate 6 descends due to its own weight and the stop rod 3 tilts. The door 2 is hooked into an upward recess 8 formed on the inside of the surface 7 so that the door 2 cannot be pulled out from there.

At that time, even if the position of the stopper 3 is incorrect vertically, the door 2 can be moved to the box 1.
When pressed, the locking rod 3 is guided by the ■-shaped side of the notch 5, pushes up the downwardly inclined surface 7 of the hooking plate 6, and locks thereon.

In addition, since the ■-shaped notch 5 is provided on the front surface of the guide tube 4 that stands perpendicularly to the front surface of the box, the notch 5 between the locking rod 3 and the hooking plate 6
The locked state inside can be easily checked from the outside.

Next, use your fingertips to move the locking plate 6 slightly upwards to lock the locking rod 3.
is removed from the upward recess 8, allowing the door to be opened.

Note that the hook plate may be formed by punching out a stainless steel plate 6a as shown in FIG.

Furthermore, as shown in FIG. 2, if a through hole is made in the guide tube 4 and a stop pin 9 is inserted into the hole, the lock plate 6 locked to the stop rod 3 will not rise unnecessarily, so that one door 2 can be securely locked. do.

In short, in this invention, when the door 2 is closed, the stop rod 3 is guided by the ■-shaped side of the notch 5, even if its position is incorrect up and down, and the lock plate 6 is moved up and down to lock there. If you cannot open the door, then push up the latch plate 6 with your fingertips and you will be able to open the door immediately.
This has the effect that whether or not the door is locked can be easily and reliably inspected from the front of the door 2.
