Description

[Detailed description of the invention] [Industrial field of application] This invention is a hanger for displaying displays, frames, lights, and other interior structures in stores, homes, exhibition halls, etc. on cables such as long thin wires. The present invention relates to a flexible locking device that can adjust the length and tension of the cable body when positioning the cable at any position or attaching it to each surface of the floor or ceiling.

[Prior Art] Conventionally, when displaying items by hanging them indoors or in a display window, etc., the hanging position, height, etc. are arbitrarily selected in order to increase the display effect and space effect. Mounting metal fittings that can be fixed in position are known from Japanese Utility Model Application No. 149784/1984 and Japanese Utility Model Publication No. 14040/1988.

[Problem that the invention attempts to solve]

However, in this conventional example, if the inner cylinder protrusion is pushed from the outside, there is a risk that the slip or chuck may come off and fall off, making it difficult to operate when the safety cover is covered and once the locking device is attached, it is extremely difficult to remove it. In addition to being troublesome, it is inconvenient to replace if it is buried in the floor or ceiling, and depending on the decoration, the latching device and balance may be inconsistent, causing an aesthetic problem. There were many accidents caused by slips, which were extremely troublesome to operate, and which hindered workability when changing display positions.

The present invention accurately eliminates these conventional drawbacks,
The movement and locking of the locking device fixed on the cable body can be performed extremely easily and quickly, and its positioning and handling can be done with a single touch, greatly improving work efficiency, giving it a good appearance and a high level of safety. It is intended to provide a locking device.

[Means for solving problems]

In the present invention, a tapered surface is formed in a casing 2 that can integrally connect a hanging member 1 such as a hanger with connecting members 6 ₁ , 6 ₂ , and a plurality of balls 5 , 5 in contact with this tapered surface are idle. A floating body 3 having a hollow hole into which a cable member W such as a wire can be inserted is elastically deployed by a spring 4 having one end fixed.
Balls 5, 5 are disposed so as to be freely projectable and retractable in the hollow hole so as to be able to pinch the cable body W inserted into the hollow hole,
The floating body 3 is slidably housed in the casing 2 so that one end of the floating body 3 protrudes outside the casing 2, and a stopper is provided for stopping and fixing the movement of the floating body 3 sliding in the casing 2. Part 6
This is a flexible locking device characterized in that the projecting end of the floating body 3 is removably equipped with the following.

〔Example〕

In the illustrated example, a casing 2 to which a hanging member 1 such as a hanger can be connected by a connecting member of an appropriate means such as welding, screwing, fitting, etc. is a hollow cylindrical body having through holes open at both upper and lower ends. A movable body 3 which holds at least two or more balls, for example, three balls 5, 5, 5 so as to be movable toward and away from the hollow portion, is provided so as to be movable in an axial direction perpendicular to the direction in which the balls 5 move toward and away from each other. There is. The floating body 3 is a pipe body into which a cable member W such as a wire can be inserted in the axial direction between the balls, and has a cone fitted to a tapered surface formed on the upper inner circumferential surface of the casing 2 at approximately the center thereof. The cone part 8 has three ball insertion holes 9, each holding a ball 5, and the upper end of the floating body 3 projects from the casing 2. The tapered surface of the casing 2 has a narrow upper end, so that when the balls 5 are near the upper open end of the casing 2, the spacing between the balls 5, 5, 5 is smaller than when the balls 5 are far from this open end. The balls 5 are restrained from coming into contact with each other in this manner, and the balls 5 are locked with or slid onto the rope body W by the contact and separation between the balls 5, 5, and 5.
The floating body 3 is usually formed by a spring between a spring presser 4', which is provided with one end fixed in the casing 2, and a stepped portion of the cone portion 8 so as to receive a force pushing toward the upper end of the casing 2. 4 is interposed, and the casing 2 and floating body 3 are in a state where they can be firmly locked to the cable body W.

Furthermore, a screw 10 is cut on the outer surface of the upwardly projecting end of the floating body 3, and a cap nut, for example, as the stopper member 6 is screwed therein in a detachable manner. Further, a screw 7 is provided on the outer periphery of the casing 2, and a connecting member 6
It is convenient to screw together nuts _{No. 1} and ₆ and hold the hanging member 1 between the nuts. In this case, the stopper member 6 and the coupling member ₆₁ may be integrally formed into a cap shape that also covers the casing 2.

Further, in the ones shown in FIGS. 1 to 4, the stopper member 6 comes into contact with the casing ₂ via the coupling member ₆₁ and is locked, but in the one shown in FIG.
The through hole is made larger than the outer diameter of the stopper member 6, and the stopper member 6 is directly abutted against the casing 2 and locked.

In the case of FIGS. 4 and 5, the casing 2 is covered from above and below with cap nuts of connecting members 6 ₁ and 6 ₂ ,
The aesthetically designed one shown in FIG. 5 is further provided with a hole 12 to prevent the cable member W from slipping out.

By adjusting the screwing depth of the coupling member ₆₁ , the position of the stopper member ₆ can be regulated when the stopper member 6 contacts the casing 2 via the coupling member 61. By adjusting the depth of screwing into the floating body 3, it is possible to make it suitable for the degree of locking, the thickness of the cable body W, etc. In addition, the screws 7 of the casing 2 do not need to be provided all around the circumference; it is sufficient to place them at the necessary positions.
It is also good to form a rough knurled surface to prevent slipping on the outer periphery of the stopper member 6 to be screwed together, the nut coupling members 6 ₁ , 6 ₂ , etc.

Furthermore, the casing 2 and the hanging member 1 can be formed integrally, or the stopper member 6, the nut or the coupling member 6 ₁ , 6 ₂ of the cap nut, etc. can be colored as appropriate and replaced with a member of a color that harmonizes with the surroundings. By doing so, it is possible to create a configuration that also enhances the aesthetic appearance.

In the figure, 13 is a hook provided on the ceiling surface, etc., and 14 is a washer.

Therefore, when attaching the flexible lock to the cable W suspended from the ceiling etc. via the hook 13 as shown in FIG. When the floating body 3 protruding from the casing 2 is pushed downward against the elasticity of the spring 4 through the stopper member 6, the balls 5, 5, 5 become free, and the cable body 3 is loosened. When the cable W is inserted and the downward pressure is stopped at an appropriate position, the floating body 3 is returned to the upper position by the spring 4, and the cable body W
is held in pressure contact between the balls 5, 5, 5, and the flexible locking device is fixed to the cable body W. After that, the stopper member 6, which had been loosened, is attached to the casing 2.
Alternatively, the coupling member 6 is screwed in and fixed until it abuts on _{the 1} , and in addition to the elasticity of the spring 4, the balls 5, 5, 5 firmly hold the cable body W, and the flexible locking device slides off the cable body W. It can be used in an extremely stable state without any problems.

[Effect of idea]

The present invention provides a stopper member 6 for stopping and fixing the movement of the floating body 3 sliding in the casing 2.
By attaching and detaching it to the protruding end of the cable, the fixation of the flexible locking device to the cable body becomes more secure, and heavy objects can be hung stably.The flexible locking device is easy to operate and has a good appearance. It can be used as a tool.
