Description

  The present invention relates to a monkey breeding cage with a locking device that houses and breeds monkeys for laboratory animals.

  Monkeys such as cynomolgus monkeys, rhesus monkeys, squirrel monkeys, marmosets and baboons are used as experimental animals for confirming the efficacy and safety of pharmaceuticals. These monkeys are housed one by one in monkey breeding cages.

As shown in FIG. 7, the monkey breeding cage has a lattice shape for the whole of the front, top, bottom, and side as shown in FIG. Forming.
The monkey breeding cage 100 is suspended on a bar 106 provided on a wall surface or the like by a suspension 101 formed on the back surface thereof, and used in a state where a plurality of monkey breeding cages are arranged as shown in FIG. .
Each monkey breeding cage 100 is formed in a size capable of accommodating monkeys such as cynomolgus monkeys, rhesus monkeys, squirrel monkeys, marmosets, baboons and the like.

The monkeys are allowed to enter and leave the front door 102 during medication and inspection. In addition, sliding doors 103 are formed on both sides of the monkey breeding cage 1, and the adjacent monkey breeding cages 1 and 1 are brought close to each other to open the opposite side doors 103 and 103 for breeding. The monkeys are able to come and go.
These doors 102 and 103 are locked by a latch 105, a padlock 104, or the like, and a keeper unlocks the door as necessary to open and close the door.

  However, some monkeys housed in the monkey breeding cage 1 learn simple actions while watching human unlocking operations many times. Monkeys who learned movements sometimes took out their arms and hands from the gaps in the lattice on the front and bottom, and while moving the latches to imitate human movements, they pulled out the locks and unlocked them. . In addition, because there is nothing else, the padlock was violently pulled all day long for about half a year, causing it to break, opening the door, and escaping.

  When a monkey escapes, it takes about half a day of catching work by about 10 keepers, and wastes time and useless labor, and the escaped monkey is in a normal state due to chased stress. There was a disadvantage that data could not be obtained.

  On the other hand, even if the mechanism of the lock, such as a latch or padlock, is complicated to prevent the monkey from escaping, the monkey may be destroyed by violently messing around for a long time, and as shown in FIG. Since a large number of monkey breeding cages are used side by side, increasing the number of locking / unlocking procedures and making them complicated may take time to open and close the doors of the breeding cages, which may interfere with daily work.

  The problem to be solved is that, in order to prevent monkeys from escaping, if a lock mechanism with a complicated mechanism is used or the procedure of locking and unlocking is complicated, it takes time to unlock each monkey breeding cage. The present invention is formed with a simple structure without complicating the mechanism of the lock, and can be locked and unlocked by a simple operation procedure. An object is to provide a locking mechanism that is not locked.

  In order to solve the above-mentioned problem, as described in claim 1, a cage body having a lattice structure that can accommodate a monkey with an opening, a door member that opens and closes the opening of the cage body, and the door member is closed. A saddle member capable of sliding up and down from a lower limit position that can be constrained to a state to an upper limit position that can be opened and closed, and a swing stopper that swings by its own weight to an interference position that restricts the saddle member to the lower limit position A monkey breeding cage with a locking mechanism is provided.

  According to a second aspect of the present invention, the door member is slidably supported so as to be able to advance and retreat in the direction of the flange member, and a support arm is extended from the flange member so as to be pivotable in the vertical direction. A monkey breeding cage with a locking mechanism is provided.

  As described in claim 3, a cage main body having a lattice structure that can accommodate monkeys with an opening, and a door member that can slide up and down from a lower limit position that closes the opening of the cage main body to an upper limit position that opens. The swing stopper includes a swing stopper that swings by its own weight up to an interference position that restricts the door member to its lower limit position. The swing stopper is formed with a recess that restricts the swing operation by engagement of the door member. A monkey breeding cage with a locking mechanism is provided.

  As described in claim 1, after restricting the movement of the eaves member that restrains the door member in the closed state at the lower limit position by the swing stopper, the swing stopper is rotated to remove the restriction, and the state is maintained. By sliding the heel member to the upper limit position and enabling the opening and closing operation of the door member related to this heel member, it is necessary to coordinate both hands according to a predetermined procedure for the swing stopper and the heel member when unlocking Therefore, with the lattice structure of the cage body, while ensuring the openness of the accommodation side and restricting the cooperative operation of both hands to prevent unlocking from inside the cage body, a special unlocking member such as a key lock Therefore, the simple and reliable locking control can be achieved with a simple configuration using the flange member and the swing stopper.

  As described in claim 2, the hook member is fitted and restrained in the sliding direction of the door member at the lower limit position thereof, the door member is restrained via the support arm, and the hook member is rotated upward to freely move. By opening and closing the door member by sliding the door member forward and backward at the upper limit position possible, and by folding the protruding support arm upward or downward to hold the door member in that position, In addition to functioning as a locking mechanism for a sliding door that requires a large slide stroke, the door arm can be held in that position by folding the support arm protruding along with the slide stroke so as not to interfere.

  As described in claim 3, the opening operation of the door member is prevented by the swing stopper, and the unlocking operation is restricted by engaging and restraining the swing stopper by the recess, while the swing stopper is rotated. Disengagement from the door member, and in this state, the door member is slid from the lower limit position so that the door member can be opened. In addition to securing the openness of the accommodation side by the lattice structure of the cage body, it is necessary to require a special unlocking member such as a key lock while restricting the cooperative operation of both hands to prevent unlocking from inside the cage body In addition, simple and reliable locking control can be performed with a simple locking mechanism using a swing stopper.

  A monkey breeding cage with a locking mechanism according to the present invention will be described below with reference to FIGS. FIG. 1 is an overall side view of a monkey breeding cage with a locking mechanism according to the present invention.

The monkey breeding cage 1 with a locking mechanism (hereinafter referred to as “bred cage 1”) is formed with an opening 11 on the back side of the side surface of the cage body 10, and a sliding side door 2 is provided on the rear side of the cage cage 10. Install it so that it can move forward and backward along the side. A connecting tool 20 is provided on the lower front side of the side door 2, and one end of the long plate-like support arm 3 is pivotally supported through the slot 31 so as to be swingable.
A handle 30 is formed on the other end of the support arm 3, and the other end including the handle 30 is projected to the front of the breeding cage 1. The side door 2 is opened and closed by operating the support arm 3 forward and backward by the pulling portion 30.
