Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a tensioning device for cords for displaying displays, frames, lights, and other interior structures in stores, homes, exhibition halls, etc. It is something.

[Prior art]

In recent years, the present inventor has proposed and put into practical use a mounting bracket in which a sleeve is loaded with a spring in the casing and can be fixed at any position on a long and thin cable body using a ball held in the sleeve. However, when using the mounting bracket to secure the cable to a ceiling, floor, or wall, the mounting bracket must be locked to a hook or bracket fixed to the mounting surface, or the bolt portion may be integrally formed with the mounting bracket. It is common practice to bury it in the ground and attach it to the mounting surface.

[Problem that the invention attempts to solve]

However, in this case, the axis of the casing is fixed or can only be rotated in a certain direction, and it is inconvenient and problematic to tension the cable in any direction. If the cable body is forcibly stretched in a direction different from the axial direction of the casing, force due to the bending is applied to the attachment fitting, which is undesirable.

The object of the present invention is to accurately eliminate this conventional drawback and provide a cable tensioning device that can tension the cable in any direction.

[Means for solving problems]

The present invention provides a sleeve 6 which has a hollow casing 1 having a tapered surface 2 on its inner surface, a hollow hole 7 through which a cable member W such as a wire can be inserted, and a cone portion 8 that fits into the tapered surface. The tapered surface 2 is biased by a spring 11, and a ball 5 is provided in a ball insertion hole 9 provided in the cone portion 8 of the sleeve 6 so as to be protrusive and retractable, and a cable member is provided between the balls 5, 5... In a grip mechanism capable of inserting and holding W, a U-shaped bracket 3 is rotatably connected to the casing 1 by a pivot 10, and the bracket 3
Insert the mounting member 13, which is a threaded rod with a head larger than the hole 3', into the mounting hole 3' formed in the hole 3', and secure the bracket 3 between it and the head using a branch nut 14 or a plate. This is a cable tension device characterized by being rotatably supported.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

The casing 1 is a hollow cylindrical body, and one end has a diameter that gradually decreases and a tapered surface 2 is formed on the inner surface as a contact surface.
The other end is provided with a bracket 3 rotatably via a pivot 10. Inside the casing 1 is a sleeve 6 that holds at least two balls, for example three balls 5, 5, 5.
It is held so that it can freely move in the axial direction.

The sleeve 6 is a pipe body having a hollow hole 7 so that the cable body W can be inserted from the outside in the axial direction between the balls 5, 5, and has a tapered surface of the casing 1 approximately in the center. A cone portion 8 is formed to fit into the cone portion 2, and three ball insertion holes 9 are provided in the cone portion 8 to hold the balls 5, respectively. The balls 5, 5, 5 are enclosed in a state where they can be separated and regulated by the tapered surface 2 by the free movement of the sleeve 6, and are set to be able to be fixed and slid onto the cable body W. There is. The pin portion of the sleeve 6 that follows the small diameter portion of the cone portion 8 is formed into a male thread and is provided so as to be able to protrude from the casing 1.
The large diameter part of the sleeve 6 is formed into a stepped part to serve as a spring seat, and the sleeve 6 is placed between the cone part 8 and the tapered surface 2 between it and a spring retainer 4 provided inside the casing 1 as a spring seat opposite to this spring seat. A spring 11 is provided that biases in the direction of fitting and abutting. A male screw is provided on the pin portion of the sleeve 6, and a stopper cap 12 consisting of a female screw is screwably attached thereto. This stopper cap 12 has an insertion hole 7' for the cable member W, and has a knurled surface formed on its outer surface.

The bracket 3 is a U-shaped member, and the casing 1 is rotatably connected to the opposing side pieces by pivots 10. The bracket 3 is fitted into a hole 3' formed in the bracket 3, and can be attached to a floor, wall, ceiling, etc. The mounting member 13 and the bracket 3 are rotatably connected to each other about an axis perpendicular to the axis of the pivot portion 10.

The mounting member 13 includes the head and the bracket 3.
A bolt is used, which is made up of a neck portion and a threaded rod portion that fit into the hole 3' and serve as a sliding surface, and a nut 14 is fixed to the end of the threaded rod portion on the neck side using adhesive or other appropriate means. However, in place of the nut 14, there is a plate with a screw hole for screwing into the screw (not shown).
Alternatively, a plate having a hole that fits into a concave ring formed in the bracket 3 may be used, and the plate may be attached to the mounting surface with screws, tapping pins, or the like.

Then, the bolt as the mounting member 13 is screwed into a female threaded portion of the anchor, nut, tapped surface, etc. using the nut 14 portion, and is fixed to the mounting surface. In this case, the bracket 3 is rotatable about the axis of the mounting member 13, and the casing 1 is attached to the pivot 10, which is a pivot perpendicular to the axis of the mounting member 13.
Since it is freely rotatable within a range of 180° or more, the casing 1 can swing in a predetermined direction.
The cable body W held by the balls 5, 5, 5 can be tensioned in a state aligned with the axial direction of the casing 1.

[Effect of idea]

In the present invention, a U-shaped bracket is rotatably connected to the casing at a pivot point, a screw rod mounting member with a head larger than the hole is inserted into a mounting hole formed in the bracket, and a branch By rotatably supporting the bracket with the head using a nut or plate, the bracket can be supported on various fixed surfaces including walls with screw rods, and a wire grip mechanism is provided on the bracket. The casing is rotatably supported around the cable body, and the casing can be tilted in any direction at the pivot point, and can be easily used for tensioning the cable body, and the grip Since the casing can be supported along the wire, the tensioning work can be carried out efficiently without damaging the wire or the like.
