Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a locking device in a partition in which a plurality of panels are foldably connected by a hinge body.

[Prior Art] Conventionally, as a partition for folding doors, opening / closing walls, etc.,
It is known that a plurality of panels 2 are foldably connected by a hinge body 1. This partition is a fully closed state by extending the panel 2 in parallel with the rails. The locking means is, as shown in FIG. A movable roller 56 is projected, and this roller 56 is elastically biased upward by a spring so that when the panel 2 is closed, the roller 56 elastically elastically locks and locks in the upper rail 3b. It was only.

[Problems to be solved by the invention] However, in the above-described conventional example, the roller 56 is certainly locked in the upper rail 3b in the closed state, but an external force is applied. Then, the roller 56 that has been elastically locked may come off from the upper rail 3b, which is not sufficient as a locking device.

The present invention has been made in view of the above-mentioned points, and the purpose of the present invention is to lock the drop rod securely by fitting it to the rail, and to take the state in which the drop rod is detached from the rail. Not only can the grip be securely held by the locking of the stop projection and the constriction of the spring body, but the locked and unlocked states can be visually confirmed from the outside, and the lock can be locked when the operating part is slid to hold it It is an object of the present invention to provide a partitioning lock device in which the protrusion and the constricted portion of the spring body are smoothly locked and the locking is hard to release.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a partition locking device of the present invention rotatably connects adjacent panels 2 with a vertically long hinge body 1 and rails a plurality of panels 2. In the partition mounted movably along 3, the drop bar 4 which can be freely projected from the end of the hinge body 1 can be fitted into the rail 3, and the operating part 5 for moving the drop bar 4 up and down is hinged. When the operation unit 5 is slidably mounted on the outer surface of the body 1 and a vertical recess 39 is formed on the back side of the operation unit 5 and opens in the longitudinal direction, and the operation unit 5 is moved in a direction in which the drop rod 4 is separated from the rail 3. A drop rod 4 fitted in the vertical recess 3
A locking projection 40 that is exposed to the outside when is moved in the direction of fitting into the rail 3 is provided so as to project to the outer surface of the hinge body 1, and a substantially U-shaped spring body 60 is provided inside the vertical recess 39 of the operation portion 5. At the same time, both side pieces 61 of the spring body 60 are bent in a V shape so that the central portions of the both side pieces 61 in the vertical direction are close to each other to form a constricted portion 62 which is locked by the locking projection 40. Constriction of both side pieces 61 of the body
The inclination of the inclined portion 61a above 62 is made gentle with respect to the vertical direction, and the inclination of the inclined surface 61b below the constricted portion 62 is made steep with respect to the vertical direction.

[Operation] Then, the operating portion 5 is slid up and down to fit the drop rod 4 into the rail 3 to lock it, or to drop the drop rod 4
Is released from the rail 3 to release the lock, and the lock is not released unless the operating portion 5 is operated when locked, so that the lock can be reliably performed. Further, when the operating portion 5 is moved to the unlocked side, the locking projection 40 elastically locks with the constricted portion 62 of the spring body 60 and the drop rod 4 is detached from the rail 3 and the unlocked state is maintained. It has become so. In the unlocked state, the locking projection 40 is a vertical recess.
Since it is inside 39, it is not exposed to the outside, and the locking protrusion 40 is exposed to the outside in the locked state.
Whether or not the 40 is visible from the outside can be determined at a glance whether it is locked or not. Further, when the operating portion 5 is slid to lock the locking projection 40 to the constricted portion 62, the sloped surface is gentle.
It is smoothly locked by being guided by 61a, and after being locked, it can be reliably locked by the steep slope 61b so as not to come off.
