DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension bolt device in a moving partition capable of completely preventing an unexpected accident due to looseness of a suspension bolt.

[0002]

2. Description of the Related Art Panels for moving partitions include runners,
It is suspended so as to be movable and movable via a suspension bolt vertically attached to the runner and a socket screwed to the suspension bolt.

[0003] That is, the socket for hanging the panel is
The panel protrudes upward from the upper end of the panel, and is connected to the runner by being screwed to a suspension bolt.
Therefore, the panel can be freely moved by the runner moving along the guide rail installed on the ceiling. In addition, the runner, the suspension bolt, and the socket can be arranged in one set before and after the panel to support the entire weight of the panel.

[0004]

In such a conventional technique, if the suspension bolt is loosened with respect to the socket, a heavy panel may fall on the floor surface, which may cause an unexpected accident. The suspension bolts are rotatably suspended from the runner so that the panel can be turned. Therefore, the suspension bolts are liable to be loosened. Troubles in maintenance work, etc.
There are special circumstances that are extremely inconvenient.

In view of the above-mentioned problems in the prior art, the object of the present invention is to form a large-diameter male screw portion and a small-diameter male screw portion into a suspension bolt, and combine the lock nut and the restraining member to loosen the suspension bolt. An object of the present invention is to provide a suspension bolt device in a movable partition which can completely prevent an unexpected accident caused by the above and can freely remove the suspension bolt from the socket as needed.

[0006]

According to the present invention, there is provided a suspension bolt having a large diameter male screw portion and a small diameter male screw portion formed vertically on a lower surface of a runner so as to be rotatable. And a socket for screwing the panel into a small-diameter male screw, suspending the panel, a lock nut screwing to the large-diameter male screw, and a restraining member for restraining the socket and the lock nut from rotating relative to each other. The gist of the invention is that the restraining member includes a vertically open frame through which the socket is inserted, and a positioning leaf spring attached to the frame.

[0007]

According to the structure of the invention, the restraining member is
Lock the socket and lock nut so that they cannot rotate relative to each other. That is, even if the suspension bolt tries to rotate in the loosening direction,
Since the lock nut screwed into the large-diameter male thread of the suspension bolt has a higher traveling speed than the socket screwed into the small-diameter male thread, the lock nut is positively pressed against the socket and the suspension bolt comes out of the socket. Can be reliably prevented. In addition, the restraining member allows the suspension bolt to be screwed into the socket to an arbitrary depth by allowing the relative rotation of the socket and the lock nut, and the suspension bolt can be freely removed from the socket.

The restraining member is moved upward, for example, and the upper and lower open frames are commonly engaged with both the socket and the lock nut, thereby restraining the two members from rotating relative to each other and moving the lower member downward. By releasing the engagement with, relative rotation between the two can be permitted.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

[0010] The suspension bolt device in the moving partition,
A suspension bolt 21 hanging from the runner R, a socket 23 for suspending the panel P, a lock nut 22, a restraining member 25
(FIGS. 1 and 2).

The moving partition has a large panel P constituted by attaching surface materials P2, P2 to both surfaces of a frame material P1, and a runner R for suspending the panel P so as to be movable. However, a pair of runners R are provided at both front and rear ends of the panel P, and the panel P moves indoors by moving along the guide rail GR installed by the runners R and R on the ceiling of the room. The space can be arbitrarily partitioned.

[0012] The runner R and the panel P are
Socket 23 and support block 2 integral with socket 23
4. Note that a lock nut 22 is mounted above the socket 23. The socket 23 has a hole 24a formed in the center of the support block 24.
The support block 2 is inserted by welding the lower end to
4. The support block 24 is housed inside the frame member P1, and can support the panel P by engaging with the frame member P1 from below. The suspension bolt 21 is rotatably suspended from the lower surface of the runner R.

The suspension bolt 21 has a large-diameter male thread portion 21.
a and a small diameter male screw portion 21b are formed vertically,
The pitch of the former shall be larger than that of the latter.
The lock nut 22 is screwed into the large-diameter male screw portion 21a, and the socket 23 is screwed into the small-diameter male screw portion 21b via a female screw portion 23a formed at an intermediate portion of the socket 23. The lock nut 22 is formed in a shape in which four sides are cut into a square from a disk having the same diameter as the socket 23. On the other hand, on the outer periphery of the socket 23, the long flat portion 2
3b, 23b and short flat portions 23c, 23c are formed.

A restraining member 25 is attached to the socket 23 and the lock nut 22. The restraining member 25 includes a vertically open rectangular frame 25a through which the socket 23 is vertically inserted,
A pair of leaf springs 25 attached to the inner surface on the short side of the frame 25a
b, 25b. The frame 25a is a socket 23
Long flat portions 23b, 23b and one of the lock nuts 22
The length of the short side is set so as to match the opposite side of the set (FIGS. 2 and 3), and the height of the frame 25a is set to be substantially the same as the length of the long flat portions 23b, 23b. (FIGS. 2 and 4). The upper ends of the leaf springs 25b, 25b that are bent inward toward the suspension bolts 21 are located at substantially the same height as the upper end of the frame 25a (FIG. 1, FIG.
4), the lower end protrudes below the frame 25a and is bent in a U-shape so as to face each other.

The restraining member 25 is moved upward to engage the upper ends of the leaf springs 25b, 25b with the upper surface of the lock nut 22 (solid line in FIG. 4).
The socket 23 and the lock nut 22 can be restrained from rotating relative to each other while positioning the whole via the b and 25b. The opposite long side of the frame 25a is the socket 23
Long flat portions 23b, 23b and one of the lock nuts 22
This is because they are commonly engaged with the opposite sides of the set (FIGS. 2 and 3).

That is, the suspension bolt 21 at this time is
The lock nut 22 advances toward the socket 23 by rotating in the loosening direction with respect to the socket 23,
The traveling speed of the lock nut 22 in this case is
3 is higher than the traveling speed of the suspension bolt 21 with respect to the position 3 This is because the large-diameter male screw portion 21a into which the lock nut 22 is screwed is formed at a larger pitch than the small-diameter male screw portion 21b into which the socket 23 is screwed. Therefore, the restraining member 25 restrains the socket 23 and the lock nut 22 so that they cannot rotate relative to each other, thereby actively pressing the lock nut 22 against the socket 23 and locking the rotation of the hanging bolt 21 with respect to the socket 23 in the loosening direction. It is possible to reliably prevent the suspension bolt 21 from coming out of the socket 23.

The restraining member 25 can be moved downward to the lower ends of the long flat portions 23b, 23b of the socket 23 by disengaging the upper ends of the leaf springs 25b, 25b from the upper surface of the lock nut 22. (Two-dot chain line in FIG. 4). At this time, the upper ends of the leaf springs 25b, 25b
The restraint member 25 is positioned by engaging the short flat portions 23c, 23c of the socket 23, and the frame 25a is disengaged from the lock nut 22 and is engaged only with the socket 23. That is, the restraining member 25 at this time
Can allow relative rotation of the socket 23 and the lock nut 22. Then, if the lock nut 22 is loosened with respect to the suspension bolt 21 and the suspension bolt 21 is rotated with respect to the socket 23, the suspension bolt 21
3 can be screwed to an arbitrary depth and can be pulled out from the socket 23.

[0018]

As described above, according to the present invention, a suspension bolt having a large-diameter male screw portion and a small-diameter male screw portion, a socket to be screwed to the small-diameter male screw portion, and a large-diameter male screw portion are screwed. By combining the lock nut and the restraining member, the restraining member can restrain the socket and the lock nut so that they cannot rotate relative to each other. In addition to this, it is possible to allow the relative rotation of the socket and the lock nut as needed, freely remove the suspension bolt from the socket, and perform the maintenance work of the runner without any trouble. is there.
