[0008]

[Embodiment of the invention]

 Hereinafter, a wire holding fitting according to an embodiment of the present invention will be described with reference to the drawings. The wire holding fittings according to the present embodiment can be attached to a body to be attached, for example, a ceiling wall, and can be stretched while holding both ends of the wires. The display items are suspended from the stretched wires.

Hereinafter, details of the wire holding fitting will be described. As shown in FIGS. 1 to 3, the wire holding fitting 1 is inserted into a ceiling wall 2 which is an attached body and is fixed via a pair of nuts 3 in a rod-shaped screw body (an example of an attached body) 4. On one end side, a screw portion 5a that can be screwed (engaged) with the lower end screw portion 4a of the rod-shaped screw body 4 is formed, a space portion 5b is provided in an intermediate portion, and a spherical receiving portion 5c is provided on the other end side. And a spherical body (spherical) that is disposed in the space 5b of the holding member 5 and slidably, that is, swingably held by the spherical seat 5c. ) And a wire holder 7 inserted through and supported by the spherical body 6. The spherical receiving portion 5c for supporting the spherical body 6 only needs to be able to support a part of the bottom of the spherical body 6 from below. In some cases, the spherical receiving portion 5c is supported by line contact (of course, a small width). It is also possible to use one that does so.

Further, the spherical body 6 into which the wire retainer 7 is inserted is positioned around the axis a of the rod-shaped screw body 4 in a plane including the axis a of the rod-shaped screw body 4, that is, in a vertical plane. From the lower end position to a predetermined horizontal position in an angular range of approximately 90 degrees (accurately 90 degrees, but a range of about 80 to 90 degrees is allowed). . That is, at a predetermined position on the side surface of the cylindrical holding member 5, a groove 5d capable of guiding the cylindrical distal guide portion 7a of the wire retainer 7 is formed, and the depth h of the groove 5d is just The tip guide portion 7a is set to a horizontal position (shown by a virtual line in FIG. 1). A cutout 5e for drawing out the wire W from the base end (rear end) of the wire holder 7 is formed at a position of the holding member 5 opposite to the groove 5d. Normally, the notch 5e has the same shape and size as the groove 5d, but may have a shape and size according to the thickness of the wire in some cases. In the holding member 5, a stopper 8 for preventing the spherical body 6 from moving upward is screwed into a predetermined position.

On the side of the holding member 5, a first positioning screw 11 for fixing rotation with respect to the rod-shaped screw body 4 and a second positioning screw 12 for fixing swinging of the spherical body 6 are respectively provided. It is screwed. Next, a method of using the wire holding fitting 1 will be described. First, as shown in FIG. 1, a rod-shaped screw 4 is inserted into a ceiling wall 2 of a display space for articles, and the rod-shaped screw 4 is fixed using a pair of nuts 3.

Next, a spherical body 6 into which a wire retainer 7 is inserted is screwed into a lower end threaded portion 4a of the rod-shaped threaded body 4 in a space 5b thereof. The holding member 5 is attached by screwing 5a. When the holding member 5 is attached, the holding member 5 is rotated so that the groove 5d formed on the side surface thereof faces the direction in which the wire W is stretched, and is fixed by the first positioning screw 11.

Next, when the tip guide 7a of the wire holder 7 is oriented in the direction in which the wire W is stretched, for example, when the wire W is stretched in the horizontal direction, the tip guide 7a is placed in the groove 5d and horizontally. After swinging upward so as to be in a posture (a posture rotated upward by 90 degrees from a downward vertical posture), it may be fixed by the second positioning screw 12. Since the groove 5d and the notch 5e have the same shape, the tip guide 7a of the wire holder 7 is swung toward the notch 5e with the notch 5e facing the direction in which the wire is stretched. You may make it a force. That is, either the groove 5d or the notch 5e can be used.

In this way, the wire W can be stretched horizontally by providing a pair of the wire holding fittings 1 at a position separated by a predetermined distance from the ceiling wall 2. As described above, in order to swing the distal end guide portion 7a of the wire holder 7 in a 90-degree vertical plane with respect to the axis a of the holding member 5, that is, when the holding member 5 is provided in the vertical direction, Since the wire holder 7 can be swung in the horizontal direction, when the wire W is stretched in the horizontal direction, the tip guide portion 7a of the wire holder 7 can be aligned with the tension direction of the wire W. Therefore, it is possible to prevent a large bending moment from acting on the wire holder, as compared with a conventional case in which the distal end guide portion of the wire holder can be swung only about 45 degrees, for example. .

By the way, in the above-described embodiment, the sliding body for holding the wire retainer has been described as a spherical body. However, the sliding body only needs to be able to slide (oscillate) in at least a plane including the groove. It may be a columnar member that can slide (oscillate) in a plane including the groove, that is, a columnar member whose oscillation axis is horizontal. In this case, of course, a concave arc surface capable of slidably supporting the columnar body is formed in the receiving portion.

[0016]

[Effect of the invention]

 As described above, according to the configuration of each wire holding bracket of the present invention, the distal end guide portion of the wire holder can be swung in a direction perpendicular to the axis of the holding member, that is, the holding member is vertically moved. When the wire is provided, since the tip guide portion of the wire holder can be swung in the horizontal direction, when the wire is stretched in the horizontal direction, the tip guide portion can be aligned with the pulling direction of the wire. It is possible to prevent a large bending moment from acting on the wire retainer as compared with a case where the tip guide portion of the wire retainer can be swung only about 45 degrees, for example, as in the related art.
