Description

[Detailed description of the invention] [Industrial application field] This invention is a method for displaying displays, frames, lights, and other interior structures in stores, homes, exhibition halls, etc. by connecting cables such as long wires. The present invention relates to a hanging fixture that allows the length and tension of the cable to be adjusted in order to position a hanger or the like in an arbitrary position or to attach it to each surface of the floor or ceiling.

[Prior art]

When installing shelves to place items indoors or in display windows, etc., when displaying clothes by hanging them, etc., to improve the display effect and space effect, or to change the arrangement when the items change. It is required that it be easy to arbitrarily select the height of the shelves, the position and height of hanging clothes, etc.

For this reason, recently there have been seen mounting fittings in which a sleeve is spring-loaded in a casing and can be fixed at any position on a long and narrow cable body using a ball held in the sleeve.

[Problem that the invention attempts to solve]

However, in these conventional examples, a ball insertion hole that allows the ball to move in the radial direction of the sleeve is bored like a window hole, so there is a problem that manufacturing and assembly is troublesome and costs are high. .

The purpose of the present invention is to solve these conventional problems and provide a suspension fitting that can be reliably maintained in a fixed state with the cable body, is extremely easy to manufacture and assemble, and can be mass-produced. .

[Means for solving problems]

In the present invention, a sleeve 3 having a hollow hole 3' through which a cable member W such as a wire can be inserted is provided inside a casing 2 of a hollow cylinder having a tapered surface 1 on the inner surface, and a spring 4 is used to resiliently deploy the cable. A spring guide 7 having a hollow hole 7' into which the strip W can be inserted is provided, and the spring guide 7 is integrally connected to the sleeve 3 by a coupling mechanism, and two or more balls 5, 5 are connected between the spring guide 7 and the sleeve 3. is arranged so that the cable body W can be inserted in the axial direction between the balls 5, 5, and the casing 2 has a hollow hole 9' through which the cable body W can be inserted. This hanging fixture is characterized in that a fixed spring holder 9 is fitted and locked to the casing 2.

〔Example〕

In the illustrated case, the casing 2 is a metal hollow cylinder having a through hole with both ends open, and has a tapered surface 1 on the inner wall surface, and has two or more balls, for example, three balls 5 in the hollow part. ,5,5
is sandwiched between the sleeve 3 and the spring guide 7, and the cable body W is inserted between the balls and held so as to be removable. That is, the tapered surface 1 restricts the contact and separation of the balls 5 so that when the balls 5 are on the small diameter side of the tapered surface 1, the distance between the balls 5, 5, 5 is smaller than when the balls 5 are on the large diameter side. By the contact and separation between the balls 5, 5, 5, the cable body W is engaged with or slid onto the cable body W. In addition, the outer peripheral surface has a threaded portion 10 for fixing to a mounting surface or suspended material, and a tapered surface 1.
An annular recess 11 for locking a spring presser 9, which will be described later, is provided on the outer periphery of the large-diameter end.

The sleeve 3 is a pipe body with openings at both ends and having a hollow hole 3' into which a cable member W such as a wire can be inserted in the axial direction. 8 has three ball insertion grooves 6, 6, 6 and three protrusions 12, 1.
2 and 12 are provided alternately at 60° intervals. The ball insertion groove is a notch that penetrates the sleeve in the radial direction and has the same depth as the ball diameter, and is opened at the end of the sleeve. Remaining end face 13 perpendicular to the axis
It protrudes from the center of the sleeve parallel to the sleeve axis, and serves as a coupling mechanism with the spring guide 7. The other end of the sleeve 3 is arranged to protrude from the small diameter side end of the tapered surface 1 of the casing 2.

The spring guide 7 is a pipe body with openings at both ends and having a hollow hole 7' into which the cable member W can be inserted in the axial direction.
The end facing the sleeve 3 is provided with a ball presser at a flange portion 7''.

Further, holes 14, 14, 14 into which the protruding rods 12, 12, 12 can be press-fitted are bored in the surface of the flange portion 7'' facing the sleeve 3. A coupling mechanism between the sleeve 3 and the spring guide 7, which is made up of a group of 14 holes, is provided so that the two move together in the axial direction.
In other words, the ball 5 is formed so as not to move in the axial direction with respect to the sleeve 3 and the spring guide 7 so that one does not move in the axial direction with respect to the other.

That is, the sleeve 3 and the spring guide 7 are integrally connected by a coupling mechanism and are ball holding members that hold the balls 5, 5, 5 so as to be able to move toward and away from each other, and are movable in an axial direction perpendicular to the direction in which the balls 5 move toward and away from each other. Casing 2
The balls 5, 5, 5 and the sleeve 3 are held between the tapered surface 1 and the cone portion 8 by the spring 4 which is disposed between the inner and the spring retainer 9, which will be described next, via a spring seat or directly. It is energized in the direction of contact.

The spring holder 9 is a crown-shaped cap having a hollow hole 9' through which the part of the spring guide 7 without the flange 7'' can be inserted, and is fixed to the annular recess 11 of the casing 2. Plastic, metal, etc. are used, and the casing 2
Depending on the member used, the fixing can be performed by press-fitting by elastic deformation, tightening, or other known means.

To show an example of a method for manufacturing a hanging fitting having the above-mentioned configuration, first, the sleeve 3 is inserted into the casing 2, and then the balls 5 are inserted into the ball insertion grooves 6, 5, and 5.
6, 6, and the spring guide 7 is coupled to the sleeve 3 by press-fitting the protruding rod 12 and the hole 14. Thereafter, the spring 4 is sealed with a spring presser 9 to complete the process. In this way, manufacturing and assembly can be performed extremely easily, and productivity can be improved.

When inserting/removing/sliding the suspension fitting onto/from the cable body W, push the sleeve 3 against the restoring force of the spring 4 to free the balls 5, 5, 5, and then slide the hanging metal fitting onto or from the cable body W. This is done by directly moving the spring 4 in a direction that resists its restoring force. No matter which method is used, when the pressure against the restoring force of the spring 4 is released, the cable body W is held in pressure contact between the balls 5, 5, 5, and the suspension fitting is fixed to the cable body W.

In this case, since the sleeve 3 and the spring guide 7 are integrally coupled by a coupling mechanism, there is no possibility that the two will become separated or misaligned, thereby allowing the ball 5 to move in the sleeve axial direction. 5, 5, and 5 always have their centers on a plane perpendicular to the sleeve axis to securely hold the cable body W.

Note that, as the coupling mechanism, a concave-convex fitting portion that is press-fitted, such as the above-mentioned protrusion 12 and hole 14, is often used. In that case, the sleeve 3 and spring guide 7 may be made of metal or plastic that can be press-fitted together; one may be made of metal and the other made of plastic, or both may be made of the same material.
It is also possible to provide the sleeve 3 with a recess.

In addition to press-fitting, screwing, adhesion, etc. are also possible.

In the example shown in FIG. 4, the coupling mechanism is a concave-convex fitting part, and the convex part is the flange part 7'' of the spring guide 7, and the concave part is the end part of the sleeve 3. A projecting wall 15 having a shape that fits into the peripheral edge of the
5 to connect the flange portion 7''.
If you want to reverse the concave and convex part with this type, use sleeve 3.
A constricted portion may be added to the end.

The example in FIG. 5 is an example in which the spring retainer 9 is press-fitted into the casing 2. This spring holder 9 is a washer that has a hollow hole 9' in the center through which the spring guide 7 is inserted and has a plurality of radial claw pieces on the outer periphery. The spring 4 is enclosed by pushing it in and fixing it.

In the example shown in FIG. 6, an elastic ring member having a groove is used as the spring retainer 9, and is press-fitted into the casing 2. In this case, it is preferable to provide a large number of small protrusions on the outer peripheral surface of the elastic ring member to further ensure the fixation with the casing 2.

In the example shown in FIG. 7, a screw is provided in the casing 2, and a ring member screwed onto the screw is used as the spring presser 9.

Note that the ball insertion groove 6 can be formed by providing a notch in both the sleeve 3 and the spring guide 7, for example, by protruding a groove with the depth of the radius of the ball 5 in both, or by protruding from the casing 2. It is also possible to provide a threaded portion at the end of the sleeve 3 and screw a locking stopper member onto the threaded portion.

[Effect of idea]

According to the present invention, it is possible to extremely easily manufacture a hanging metal fitting with a high function of clamping the cable body, and it is easy to assemble, greatly increasing productivity and ensuring a secure locking state.
