Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a wire or the like for attaching display shelves, displays, foreheads, lights, and other interior structures to stores, homes, and exhibitions. It is related to a body brace.

[Prior art]

In recent years, as a wire tensioning device used when suspending or fixing products on a wall surface, a sleeve is elastically mounted in a casing by a spring, and a wire grip provided with a wire grip for holding a wire by a ball held in the sleeve. An orthosis has been proposed by the present inventor and put into practical use, and when fixed to a ceiling, floor, or wall surface, it is engaged with a hook or bracket that is fixed to the mounting surface, or is screwed and mounted. There is.

[Problems to be solved by the invention]

However, this wire tensioning device is often fixedly attached and held, and it is inconvenient to tension the wire in any direction because the attachment direction must be changed. If the wire is forcibly stretched in different directions, for example, in the oblique direction, the force due to the burr is applied to the mounting member, which is not preferable, and there is a problem that the wire is damaged and fatigue is accelerated.

The present invention provides a wire tensioning device that properly eliminates the above-mentioned conventional drawbacks and can wire the wire in any direction for display changes and other image changes, and can also hold hanging articles properly and safely. The purpose is to do.

[Means for solving problems]

According to the present invention, a sphere 1 is rotatably enclosed by a socket 12 in a case 11 having a mounting portion 10 for a wall or the like, a taper hole 2 is provided in the sphere 1, and a sleeve 4 is fitted into the taper hole 2. It is inserted and urged in the direction of the taper surface by a spring 5 so as to be slidably mounted inside, and the sleeve 4 is provided with a ball 3 or a plurality of shoes in contact with the inner surface of the taper hole 2, and the balls 3, 3
The wire tensioning device is characterized in that it has a wire grip having an insertion hole 6 through which a wire W to be inserted therebetween is provided in the sleeve 4, and the sleeve 4 is led out of the case 11.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.
12 is rotatably enclosed, the spherical body 1 is provided with a tapered hole 2, a sleeve 4 is fitted and inserted in the tapered hole 2, and a spring 5 urges the tapered surface direction to slidably accommodate the interior.
The sleeve 4 is provided with a ball 3 or a plurality of shoes in contact with the inner surface of the tapered hole 2, and an insertion hole 6 through which the wire W inserted between the balls 3 and 3 is inserted is provided in the sleeve 4 to provide a wire grip. It is held and the sleeve 4 is drawn out of the case 11 and deployed to form a wire tension device.

In this case, as the mounting portion 10, an anchor bolt or a screw rod with which a nut 13 is screwed is used and is detachably connected to the cylindrical or conical case 11 by the case 11.
A female screw may be formed on the outer circumference of the to serve as a mounting portion. Also, the case 11 is a hollow cylinder which can be freely screwed or engaged releasably with the socket 12, for example, cylinders or cones, with the semi-spherical, pressing surface of the sphere 1 that is furnished to the hollow portion 11 ₁ or The ball 1 is provided with a contact member 14 having a pressing surface so that the ball 1 can roll. A sleeve 4 for holding at least two balls, for example, three balls 3, 3, 3 is slidably held in the tapered hole 2 of the sphere 1 in the sphere 1.

The sleeve 4 is a pipe body having an insertion hole 6 between the balls 3, 3 ... so that the wire W can be inserted from the outside in the axial direction. of forming a cone portion 4 ₁ configured to fit over the tapered surface, are the cone portion 4 ₁ into three ball insertion hole 4 ₂ is provided which on the ball 3 holds, respectively. The ball 3 is enclosed in a detachable and contactable state that is regulated by the tapered surface by the sliding of the sleeve 4, and is set so that it can be fixed and slid on the wire W. The end of the sleeve 4 following the small-diameter portion of the cone portion 4 ₁ is projected deployed from the sphere 1, the large diameter portion of the cone portion 4 ₁ is the spring seat formed in the stepped portion, as a spring seat that faces the spring seat the tapered hole 2 of the spherical body 1 between them by fitting the caulking or spring retainer 7, the spring 5 the cone portion 4 ₁ and the tapered surface of the sleeve 4 is energized in a direction in contact with the fitting person is being interposed deployed, The protruding end of the sleeve 4 is provided outside the case 1.

The socket 12 is a mounting member, and a plate-shaped member that caps the case 11 that is inserted into a mounting surface such as a shelf, a floor, a wall surface, or a ceiling is used. The plate-shaped member has a screw hole or a screw cylinder. Is provided with a connecting rod that can be fitted into a hole such as a pipe and a partition wall for fitting the sphere 1, and a ball receiving or roller receiving lead-out port 15 for rolling the sphere 1 is provided. The sphere 1 is held universally so that it can swing at an arbitrary angle with respect to the mounting surface.

As the case 11, a conical cylinder may be used as shown in FIG. 5A to crimp the bottom edge so that the sphere 1 can be held, or the cylindrical socket 12 can be held as shown in FIG. 5B. It may be used as an inner member to be internally mounted, and a nut sert 16 that also serves as the contact member 14 for pressing the spherical body and into which the mounting portion 10 is screwed is incorporated to facilitate assembly and disassembly.

In the example of FIGS. 6 to 7, a ball gripping ball 1 including a sleeve 4 is enclosed in a plurality of sockets 12 in a case 11 provided with a mounting part 10 to a wall or the like, for example, a screw part, so as to be rollably enclosed. At the same time, the sleeve 4 is a multi-type wire tensioning device in which each sleeve 4 is provided so as to project from the outlet 15 formed in the socket 12.

Then, when the shelf member is used as a display shelf, if the wire end is fixed to the mounting surface of the shelf member by using the wire hung from the wall or ceiling surface, the sleeve in the sphere 1 that is rollably arranged is provided. Since the wire W is inserted into the insertion hole 6 of 4 and gripped, the sphere 1 is oriented in an arbitrary direction in the case 11, and the wire W held between the balls 3 and 3 is held by the sleeve 4.
It can be stretched in a stable state that matches the axial direction of.

If one end of the sleeve 4 is pushed into the sphere 1 if necessary, the wedge state in the tapered hole 2 is dissolved and the grip by the balls 3 and 3 is released so that the shelf member can be easily moved onto the wire W. The position can be easily changed in addition to the change of direction.

[Effect of device]

According to the present invention, a sphere is rotatably enclosed by a socket in a case provided with a mounting portion to a wall, etc., a sleeve having a wire grip is provided on the sphere, and the sleeve is led out of the case. , It can be used in any direction by changing the direction of the wire from the wire mounting position, and it can be used without forcing or damaging the wire. The grip part is changed in direction to absorb the impact and prevent wire cutting accidents.In addition to changing the direction, it is also possible to change the position of the article hung by the wire easily. In addition to being practical, there are practical effects such as a simple structure and low cost production.
