Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device for a wire mesh cage, for example, for locking and unlocking a door panel mounted on a wire mesh cage used for keeping small pets such as dogs and cats indoors. For a locking device for a vehicle.

[0002]

As a cage for pets such as small dogs and cats bred indoors, there is known a wire cage type constructed using a wire mesh panel. In this wire mesh type cage, the bottom wire mesh panel (bottom plate part),
A front and rear wire mesh panel, a left and right wire mesh panel, and a ceiling wire mesh panel, and an opening serving as a doorway for pets is provided in any of the front and rear wire mesh panels and the left and right wire mesh panels, and a door panel is provided in this opening so as to be able to open and close. Is common. The door panel (between the door panel and the wire mesh panel provided with the opening) is provided with a lock device for keeping the door panel closed with respect to the opening.

[0003] In this type of lock device, while the lock can be easily released without using a key, various locks for preventing the lock from being easily released even if the pet is violated or scratched in the cage. Ingenuity is given.

In the locking devices proposed so far, usually only one position of the door panel is provided. For example, if the locking device is provided only at an intermediate height position on one side of the door panel, the inside of the cage is not provided. When the pet is rampaged at the upper and lower ends of the door panel, a part of the door panel may be bent and opened, and all the force for opening the door panel is concentrated on the lock device provided in one place. In the worst case, the locking device may be damaged. In such a case, for example, it is conceivable to equip a plurality of locking devices not only at the intermediate height position on one side of the door panel but also at the upper and lower positions. Even if a force in the opening direction acts on the door panel due to a pet being rampaged in the cage, the force can be shared and received by the plurality of lock devices. However, this requires a lock operation and a lock release operation for each lock device, which is very troublesome.

Therefore, it is desirable to provide a lock device capable of performing a plurality of locks by one operation and releasing a plurality of locks. For example, in Japanese Patent Application Laid-Open No. 8-56521, FIG. 3 shows that a metal protrusion is pulled up from a tongue-like rod by pulling up a vertical metal rod against a spring force of a spring via a protrusion knob. A locking mechanism is disclosed that is adapted to be disengaged.

However, since this locking mechanism uses the spring force of the spring to maintain the locked state between the locking projection and the tongue-shaped rod, all the locks must be released. The metal vertical rod must be lifted against the spring force of the spring until the locking projection comes off the tongue-shaped rod, and the animal access net opening / closing plate is closed when locking. It is necessary to temporarily lift the vertical metal rod against the spring force of the spring so that the stop projection is located above the tongue-shaped rod part, and there is a problem in that the operability is poor. Further, if the number of the locking projections and the tongue-shaped rods is set to three or more, smooth locking and unlocking cannot be performed, and the number of installations may be limited. Furthermore, since a coil spring is used as a spring, it is necessary to provide a cover to protect the pet in the cage from the coil spring (so that the hair of the pet is not pinched by the coil spring).

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a lock device for a wire netting cage which is excellent in operability and can perform a plurality of locks and a plurality of unlocks by one operation. With the goal.

[0008]

To achieve the above object, a lock device for a wire mesh cage according to the present invention comprises a required wire mesh panel having an opening serving as an entrance and a door panel for opening and closing the opening. Provided, a wire mesh cage, provided with a lock mechanism to keep the door panel closed with respect to the opening, a lock device of the wire mesh cage, the lock device,
A plurality of lock pieces are arranged at appropriate intervals along the longitudinal direction, and are rotatably mounted on the side of the door panel, and are detachably engaged with the side of the opening. A lock member to be stopped, and a slidable device provided near the side of the door panel on which the lock member is provided, and by being slid in one direction, locked to the lock member to prevent rotation of the lock member. And a slide member that slides in the other direction to separate from the lock member and allow the lock member to rotate.

Therefore, by simply closing the door panel and rotating the lock member and then sliding the slide member to lock the lock member, the lock operation of a plurality of lock pieces can be performed simultaneously, and the slide member can be slid. After releasing the lock of the lock member, the lock release operation of a plurality of lock pieces can be performed simultaneously only by rotating the lock member.
