Description

[Detailed description of the invention] "Industrial application field" This invention is mainly used to open and close doors that are installed in entrances and exits, partition walls, passageways, etc. of cages for breeding animals such as dogs, cats, small birds, mice, and rabbits. The invention relates to a regulating device.

``Prior art'' Conventionally, the door regulating device for these animal breeding cages has a conventional structure in which a locking ring is provided to regulate the opening and closing of the door, as seen in the technical document No. 49-41909. There are also some types of pigeon coops, such as those in which the suspended door component rotates only inward and not outward. Pet cages with a single track and a structure that allows entry only inward through a revolving door installed in the roof have been put into practical use and have been proposed in some cases. Furthermore, bird cages have lids that slide up and down to open and close.

``Problems to be solved by the invention'' The doors of various structures in the above-mentioned conventional techniques are all locked with locking rings, hooks, etc. It is not possible to create a situation other than that, and conversely, pigeon coops that have a structure that allows entry from the outside to the inside have their own advantages and disadvantages, such as the inability to lock or open the entrance. Furthermore, locking using locking rings, hooks, etc. has problems such as being difficult to operate and being relatively easy to remove.

``Means for Solving the Problems'' Therefore, the purpose of this invention is to provide a door regulating device that can be handled in three ways, despite its relatively simple structure. The door is rotatably suspended from the upper side rod of a rectangular door frame rod established in the entrance or exit, a partition wall or other passageway inside the cage, and is mounted on the lower side rod of this door frame rod, In addition, between the vertical rods of the door frame rod, there is provided a regulating rod which is wrapped so as to be movable up and down and slightly forward and backward and has a flat annular shape in plan view, and this regulating rod is mounted adjacent to the upper side of the lower horizontal rod. When the lower end of the door is disengaged from the regulating rod, and when the stopper piece provided on the regulating rod is adjacent to the back side of the lower side rod, the door is fixed via the regulating rod or only rotates into the cage. This invention relates to a regulating device for doors such as entrances and exits configured to do so.

"Operation" Next, to explain the operation state of this invention, the regulation rod 8
is the lower horizontal rod 4 that constitutes the door frame rod 2 of the rearing cage 1.
In the state shown in FIG. 3A where the doors are placed adjacent to each other, the regulating rod 8 and the lower end of the door 7 are separated from each other, and the door 7 is in an open state (free state). Therefore, the door 7 can be freely rotated as shown in the figure, so that animals, etc. can freely come out. Therefore, when attempting to close the door 7, the regulating rod 8 is pulled upward as shown by the two-dot chain line in Figure A, and the lower end of the door 7 is inserted between the two. Next, in this state, while moving the stopper pieces 9, 9 of the regulating rod 8 and the lower part of the door 7 into the breeding cage 1, the lower part of the stopper pieces 9, 9 climbs over the horizontal rod 4 on the lower side. If so, the regulation rod 8 and the stopper pieces 9, 9
lower. As a result, the lower parts of the stopper pieces 9, 9 are latched adjacent to the back side of the lower horizontal rod 4, resulting in the state shown in FIG.
Coupled with the fact that the regulating rod 8 is wound around, the regulating rod 8 is in a fixed state, and the position of the regulating rod 8 is changed from the free state due to the engagement of the stopper pieces 9, 9. Located slightly above. Therefore, the door 7 inserted into the regulating rod 8 cannot be removed from this, and the door 7 is held in a fixed state via the regulating rod 8, stopper pieces 9, 9, etc. as shown in the figure. Therefore, the door 7 is in a closed state (locked state). To release the blockage, first pull up the regulating rod 8 a little using both vertical rods 5 and 6 as guides, and then move the stopper pieces 9 and 9 to the horizontal rod 4 on the lower side.
Space them further apart. Subsequently, by further pulling up the regulating rod 8, the stopper pieces 9, 9 and the lower side rod 4 are unlatched. If the regulating rod 8 is then pushed down and placed on the horizontal rod 4, the door 7 returns to its initial state and becomes open. On the other hand, when the door 7 is rotatable only inward of the animal cage 1, so-called the door 7 is freely rotatable only to enter the animal cage 1, or when passage is allowed only in one direction in a passage, etc., When the door 7 is in the open state (same as the state in Figure 3 A), push the door 7 slightly inward of the animal cage 1, and
Pull up the regulating rod 8 and remove the inner rod material 8 of this regulating rod 8.
b is located on the outer surface of the door 7. Then regulation rod 8
If the door 7 is lowered and the stopper pieces 9 are hooked to the lower side rod 4 in the same manner as in the closed state described above, the door 7 can only be rotated inward of the animal cage 1 as shown by the arrow in FIG. For example, entrances and exits are only free to enter. When releasing the latching, the regulating rod 8 is pulled up as it is, and the stopper pieces 9 are separated from the horizontal rod 4 on the lower side. Subsequently, by further pulling up the regulating rod 8, the stopper pieces 9, 9 and the lower side rod 4 are unlatched.
If the regulating rod 8 is then pushed down and placed on the horizontal rod 4, the door 7 returns to its initial state and becomes open.

``Example'' The drawing shows an example of the present invention, and 1 is a breeding cage for animals such as dogs, cats, rabbits, etc.
On one side is an entrance/exit, an entrance/exit for a partition wall (this is a case where a partition wall is provided in the breeding cage, not shown),
A door frame rod 2 is provided that surrounds a rectangular opening opened for passage, and this door frame rod 2 is connected to an upper horizontal rod 3 and a lower horizontal rod 4 that constitute the rearing cage 1.
The left and right vertical rods 5 and 6, which are perpendicular to this, intersect in a square shape. Reference numeral 7 denotes a door that is rotatably suspended from the horizontal rod 3 on the upper side of the door frame rod 2;
It is said to be approximately the same size. The exact length of the door 7 will be described later. 8 is a flat annular shape in plan view or flattened ends at both ends, which is wrapped around both vertical rods 5 and 6 of the door frame 2 so that it can move up and down and can swing slightly (this is the front and back in Fig. 2). The regulating rod 8 is an annular regulating rod, and in this example, the regulating rod 8 is composed of an outer rod material 8a, an inner rod material 8b, and connecting rod materials 8c, 8c that connect both rod materials 8a, 8b. When the rod 8 is at its lower limit, the outer rod member 8a is placed on the horizontal rod 4 on the lower side. In this example, two stopper pieces 9, 9 are suspended from the outer rod member 8a of the regulating rod 8, and these stopper pieces 9, 9 are hung on the back side of the lower side rod 4 as described above. Can be stopped. In this case, the regulating rod 8 will be located slightly above the lowering limit (the state shown in FIGS. 3 and 4 (b)). The relationship between the length of the door 7 and the regulating rod 8, and the method of regulating the movement of the door 7 through the operation of the regulating lever 8, are as follows.

First, as described above, when the regulating rod 8 is at its lower limit, that is, when the outer rod member 8a of the regulating rod 8 is placed on the lower horizontal rod 4 (the lower horizontal rod 4 (the same applies hereinafter) is spaced apart from this regulating rod 8. So-called lower frame rod 7a of door 7
A slight gap A is formed between the control rod 8 and the control rod 8. The door 7 is opened and closed using this gap A.

Further, as mentioned above, the stopper piece 9 of the regulating rod 8,
9 is hung on the lower side rod 4, that is, when the stopper pieces 9, 9 are mounted on the lower side rod 4, the door 7 is closed by the inner and outer rod members 8b, 8a. Either the opening and closing of the door 7 is restricted by clamping the lower frame rod 7a, or the outward opening of the lower frame rod 7a of the door 7 is restricted by the inner and outer rod members 8b, and the opening of the animal cage 1 of the door 7 is restricted. The outward movement is stopped (of course, the inward movement of the animal cage 1 by the door 7 is possible, for example, to change water, food, etc., see FIG. 4B). Although the entrance and exit of the animal cage 1 has been described in detail above, it can also be used for opening/closing doors of other passages and partition walls, and if considered more advanced, it can also be used for housing, including cow sheds and pig pens. Further, depending on the case, it is also possible to make the door 7 a swingable type and to put the regulating rod 8 in an upright state.

"Effects of the invention" As detailed above, the present invention provides a rotatable door in the door frame rod of an animal cage, etc., and controls that control the rotation of the door, only inward rotation, or stoppage. Since the rod is provided on the door frame rod, the door can be handled in three ways: open, open only inward, or closed, which is very convenient and ideal for breeding animals, etc. They are useful because they can be used at any time depending on the type, habits, and level of training of the animal being raised. In addition, the regulating rod is provided on both vertical bars constituting the door frame rod so that it can move up and down or back and forth, and the stopper piece is hooked to the horizontal rod on the lower side of the door frame rod. It is easy to handle, has a reliable lock, and can be easily used by anyone.
