Description

The present invention relates to a cable holder (which may also be called a cable clip) for holding a cable such as a power cable or a communication cable in a rod-shaped material such as a support or a frame material. Here, the rod-shaped material means an elongated member, and includes not only solid members but also pipe-shaped materials and ropes.

For example, when a rod-shaped material such as a frame material is used in furniture (furniture), indoor / outdoor equipment, etc., place a cable such as a power cable along the rod-shaped material, and use the cable as a rod-shaped material so that it does not drip. It is being held.

Conventionally, as a means for holding such a cable, a band type cable disclosed in Patent Documents 1 and 2, a wire rod material disclosed in Patent Document 3, and a resin disclosed in Patent Documents 4 and 5 are used. Made holders etc. have been proposed.

Among these prior arts, the holder of Patent Document 4 is formed so that the clamp portion that elastically holds the pipe material and the cable holding portion into which the cable is fitted are separated from each other so as not to slip off from the pipe material. In the embodiment of FIG. 5A, since the clamp portion is in a cracked state, it can be fitted into the pipe material from the outside orthogonal to the clamp portion.

The same applies to Patent Document 5, in which a main body formed in a substantially C shape in a plan view so as to hug the outer periphery of the legs constituting the furniture over half a circumference or more, and a main body that protrudes to the opposite side of the opening. It has a cable holding portion provided, and the cable holding portion includes a pair of L-shaped holding pieces that sandwich and hold the cable. The pair of holding pieces is formed in a plan view L shape by a base protruding from the main body in a substantially parallel state and a hook piece protruding so as to face each other from the tip of the base, and the cable is stored by the pair of holding pieces. By forming a space and applying a cable to the hook piece from the outside and pushing and bending the hook piece, the cable is pushed into the cable storage space.

Japanese Unexamined Patent Publication No. 2007-89364 Jitsukaihei No. 6-377172 Japanese Unexamined Patent Publication No. 2001-223484 Japanese Unexamined Patent Publication No. 2014-92985 Design Registration No. 1305822 Gazette

The holder of Patent Document 5 and the holder of FIG. 5A of Patent Document 4 are excellent in workability because they can be attached to a bar-shaped material and a cable can be attached to the holder with one touch. However, in Patent Document 4, since the distance between the clamp portion and the cable holding portion is large, there is a problem that the distance between the cable and the rod-shaped material may be deteriorated, the appearance may be deteriorated, and an object may be easily caught on the cable. ..

On the other hand, in the holder of Patent Document 5, since the cable holding portion is close to the bar-shaped material (furniture legs), the cable can be run along the outer surface of the bar-shaped material, which looks good and suppresses the catching of objects. There are advantages that can be done.

By the way, in Patent Document 5, when holding a cable in a holder, a pair of hook pieces extending facing each other are pushed and bent from the outside by the cable, but since there are a pair of hook pieces and the protruding dimension is not large. In pushing the cable into the space between the pair of holding pieces, there is a problem that a large force is required for pushing.

Further, in Patent Document 5, the hook piece is pushed by the cable and once enters the cable holding space, and when the cable is separated from the tip of the hook piece, it returns to the original posture by the elastic restoring force. There is a concern that the hook will remain pressed by the cable when the cable pushes and bends the hook and hits the main body.In this case, the hook will return to its original position and cannot be deformed. The cable cannot be gripped by a pair of holding pieces. Therefore, it can be said that Patent Document 5 lacks flexibility because the range of cable thickness that can be held is narrow.

The invention of the present application has been made to improve such a situation.

The present invention relates to a holder for holding a cable in a rod-shaped material, and a typical example thereof is specified in each claim. Of these, the invention of claim 1 is
"It has a main body portion that holds the rod-shaped material and a cable holding portion that is integrally formed with the main body portion.
On the other hand, the main body portion has a non-loop shape having a pair of opening edges so that it can be expanded and deformed to be fitted and detached from the rod-shaped material.
The cable holding portion is formed on the inner surface side of the main body portion so that the cable is located between the cable holding portion and the rod-shaped material. "
It is configured as.

The invention of claim 2 embodies claim 1.
"The cable holding portion is formed by outwardly bulging a portion of the main body portion opposite to the opening, and is formed on the main body portion on the outer surface of the rod-shaped material inside the cable holding portion. A pair of overlapping tongue-shaped polymer pieces is formed so as to extend from the side of one opening edge of the main body and the side of the other opening edge so as to face each other, and between the tips of the pair of tongue-shaped polymer pieces. There is a gap in which the cable can be inserted and removed. "
It is configured as.

The invention of claim 3 embodies claim 1 or 2.
"The main body is designed so that one opening edge and the other opening edge are brought into contact with each other to form a loop-like appearance, and one opening edge and the other opening edge capable of contacting each other. Is formed with an engaging portion that meshes with each other to maintain the loop shape. "
It is configured as.

The invention of claim 4 stands from a different viewpoint from that of claim 1.
"It has a main body portion that holds the rod-shaped material and a cable holding portion that is integrally formed with the main body portion.
On the other hand, the main body portion has a non-loop shape having a pair of opening edges so that it can be expanded and deformed to be fitted and detached from the rod-shaped material.
The cable holding portion is formed on the outer surface side of the main body portion so that the cable is located outside the main body portion, and the cable holding portion has one end of both ends facing in the circumferential direction. It is formed in the shape of a tongue that is connected to the main body and the other end is a free end. "
It is configured as.

The holder according to the invention of claim 1 has a non-loop shape and can hold the rod-shaped material from the outside by widening the opening against elasticity, so that the holder can be attached to the rod-shaped material with one touch. be able to. Easy to remove.

Since the cable is sandwiched between the cable holding part and the rod-shaped material, the cable can be made into a rod-like shape simply by stacking the cable on the inner surface of the cable holding part, elastically deforming the main body, and fitting it on the rod-shaped material. Can be held in a state of being overlapped with the material. Therefore, the cable can be held in a rod-shaped material with good appearance, and it is also excellent in correspondence to the difference in the thickness of the cable.

Further, since the cable cannot be separated from the rod-shaped material unless the holder is removed from the rod-shaped material, the cable will not come off from the rod-shaped material even if an object is caught in the cable. Therefore, the cable holding function is also excellent.

When the cable is held on the outer surface of the rod-shaped material by the holder, it is also possible to form an outward convex cable holding part on the main body and arrange the cable in the internal space, but in this case, the cable holding part. However, there is a concern that the appearance may be deteriorated due to the angularity, and that the durability may be lowered due to the concentration of stress on the corners.

In this respect, when the configuration of claim 2 is adopted, the outer peripheral surface of the holder can be smoothly curved, so that the holder has a ring-like appearance as a whole and is excellent in appearance and prevents stress concentration. Can contribute to improving durability. Further, since the pair of tongue-shaped polymer pieces overlaps the outer peripheral surface of the rod-shaped material, the contact area between the holder and the rod-shaped material can be increased, which can contribute to the improvement of the holding strength. Further, since the cable is positioned between the pair of tongue-shaped polymer pieces, the position in the circumferential direction of the cable can be accurately determined. In this respect as well, the aesthetic appearance of the cable holding state can be improved.

It is possible for the main body to hold the rod-shaped material only with the elastic restoring force, but if it has only the elastic restoring force, the phenomenon of sagging will appear if it is used for a long period of time. There is a risk that the holding power will decrease. If the wall thickness is increased in order to increase the holding strength of the main body, it becomes difficult to fit it into the rod-shaped material.

In this respect, when the configuration of claim 3 is adopted, one end and the other end of the rod-shaped material are engaged with each other while holding the rod-shaped material, and the loop-shaped (cylindrical) shape is maintained as a whole, which is excessive. There is an advantage that high durability can be ensured without thickening.

In the invention of claim 4, since the cable holding portion is provided on the outside of the main body portion, the holder can be attached to the rod-shaped material first, and then the cable can be fitted into the holder. The cable can also be disconnected and disconnected with the main body attached to the rod-shaped material. Therefore, the cable locking work can be performed quickly.

Since the cable holding portion has a tongue-like shape with one end as a free end, it can be easily raised with a light force by hanging a fingertip on the free end. Therefore, the cable locking work can be performed efficiently. Further, since the cable holding portion is raised to the outside to stop the cable, even if the cable is thick, it can be pushed into the cable holding portion without any problem. Therefore, the range of cable thicknesses that can be used is wide and the value in use is high.

Next, an embodiment of the present invention will be described with reference to the drawings. This embodiment is used as a holder for holding a power cable for a lamp in a vertical frame material (post) of a partition device composed of a frame material. First, the partition device 1 will be briefly described.

(1). Partition device The partition device 1 to which the present embodiment is applied has a frame composed of metal pipes, and as shown in FIG. 2, the center support 2, the pair of left and right side columns 3, and the upper and lower side columns 3 It is provided with upper and lower horizontal frames 4 and 5 bent and formed at both ends, and an intermediate cross rail 6 fixed by welding to the upper and lower halfway height portions of the side columns 3.

A rod is fixed to the center support 2 by welding corresponding to the upper and lower horizontal frames 4, 5 and the intermediate cross rail 6, and the tips of the upper and lower horizontal frames 4, 5 and the intermediate cross rail 6 are fitted into the rod and screwed. It is fixed with. The left and right upper and lower horizontal frames 4 and 5 and the intermediate cross rail 6 have an obtuse angle in a plan view, but there is also a type having a right angle.

The partition device 1 includes a stabilizer 7 arranged in the central portion in a plan view, and an adjuster 8 is provided in the vicinity of the side column 3 in the lower horizontal frame 5. Further, a face material (blind material) 9 made of a thin material such as a cloth or a sheet material can be attached to the partition device 1. It is possible to connect a plurality of partitioning devices 1 by joints, and FIG. 1 shows a state in which the two partitioning devices 1 are arranged in opposite directions and connected.

The partition device 1 of this example partitions a space (indoor) in a state of having a certain degree of closedness while maintaining a high degree of openness, and the space on the inner angle side can be formed as a human work space. In this example, a table (desk) 10 is arranged on the inner corner side of the partition device 1 so that learning and work can be performed, and a hanging rod 11 is connected to the center support 2 so as to brightly illuminate the upper surface of the desk. The lamp 13 is hung on a hook 12 provided at the tip of the hanging rod 11.

The lower part of the hanging rod 11 is in a vertical posture, and the corresponding portion on the upper side is in an inclined posture toward the upper side of the table 10, and the hook 12 is fixed to the upper end (tip). As shown in FIG. 3A, a rod 14 is projected downward from the lower end of the suspension rod 11, and the rod 14 is inserted into the center support 2 from above and fixed with screws (not shown). ..

A power cable 15 is connected to the lamp 13, and the lamp 13 is suspended by hanging the power cable 15 directly on the hook 12, where the power cable 15 is connected to the suspension rod 11 and the center support by a large number of holders 16. It is held by 2. Therefore, in this example, the suspension rod 11 and the center support 2 are examples of rod-shaped materials, but the power cable 15 can be fixed to the upper horizontal frame 4 or the intermediate cross rail 6. In the following, a member to which the holder 16 is attached, such as the suspension rod 11 and the center support 2, is referred to as a rod-shaped material according to the claims, and is designated by a reference numeral 17.

A switch 18 is provided on the upper part of the center support column 2. Further, the lamp 13 is covered with a protective basket 19 made of a wire rod or the like.

(2). Holder The structure of the holder 16 is shown in FIG. The holder 16 is an injection-molded product using a synthetic resin such as nylon resin, and as shown in FIG. 3B, it can be fitted and removed from the rod-shaped material 17 from a direction orthogonal to its axis by using elastic deformation. A main body portion 20 having a C-shaped shape is provided therein. Therefore, the main body portion 20 surrounds a half circumference or more of the rod-shaped material 17, and the groove width of the opening (necked portion) 21 is smaller than the outer diameter of the rod-shaped material 17. The end faces of the pair of opening edges 20a sandwiching the opening 21 are inclined so as to spread in a C shape for guiding the fitting into the rod-shaped member 17 (may be in a parallel posture).

Then, a cable holding portion 22 is formed in a portion of the main body portion 20 opposite to the opening 21 by swelling and deforming the main body portion 20 in a direction away from the axis, and the cable holding portion 22 and the rod-shaped member 17 are formed. The power cable 15 is sandwiched between the two so that it can be held. Further, a pair of tongue-shaped polymer pieces 23 overlapping the outer surface of the rod-shaped member 17 is formed in a portion of the inner circumference of the main body 20 inside the cable holding portion 22, and between the tips of the pair of tongue-shaped polymer pieces 23. The power cable 15 is set so as to be able to overlap the outer surface of the rod-shaped material 17.

The cable holding portion 22 and the tongue-shaped polymer piece 23 are thinner than the main body portion 20, but the thickness can be arbitrarily set. In the present embodiment, since the outer peripheral surface of the main body portion 20 and the outer peripheral surface of the cable holding portion 22 are smoothly continuous, the appearance of a simple C-shaped ring is exhibited and the appearance is good. Further, in the used state, a light elastic restoring force acts on the holder 16 to lightly press the power cable 15, but since the cable holding portion 22 is continuous with the same thickness in the circumferential direction, it can be applied to a specific part. High durability can be maintained by preventing stress from concentrating.

The axial width (length, height) of the holder 16 can be arbitrarily set in consideration of the holding strength of the power cable 15. In FIGS. 1, 2 and 3 (A), the width is only a fraction of the outer diameter and forms a ring, but as shown by the alternate long and short dash line in FIG. 3 (C), the width in the axial direction is shown. It can also be enlarged to form a tubular shape.

The holder 16 of the present embodiment is used by first fitting the power cable 15 into the cable holding portion 22 and then pressing the holder 16 against the rod-shaped material 17 to fit the power cable 15 into the rod-shaped material. There is a method of pressing the holder 16 against the rod-shaped material 17 while holding it on the outer surface of the 17 to fit it, and either method can be adopted.

For example, in the case where the power cable 15 is stopped at the center support 2, if the power cable 15 is stopped at the upper end of the center support 2, the power cable 15 will be in a state of overlapping the center support 2. The power cable 15 can be stopped by simply pressing the holder 16 without holding it with one hand. This is an advantage that cannot be realized by Patent Document 5.

Although only one power cable 15 is displayed in FIG. 2, a plurality of power cables 15 can be stopped. Since the cable holding portion 22 has a long circumferential length and a large deformation allowance, it is also excellent in adaptability to differences in the thickness of the power cable 15. It can also be used to hold a communication cable such as a LAN cable, and it is also possible to stop the power cable 15 and the communication cable together.

As shown in FIG. 3D as a modified example, it is also possible to form a reinforcing rib 24 extending in the circumferential direction at an intermediate position in the axial direction on the outer surface of the cable holding portion 22. Alternatively, as shown by the alternate long and short dash line 20b in FIG. 3D, the width (height) in the axial direction is increased at the position of the cable holding portion 22, so that the rod-shaped material 17 can be easily fitted and detached. While holding the power cable 15, it is possible to improve the holding function and the durability of the power cable 15.

The partition device 1 can be used in various layouts. An example is shown in FIGS. 4 and 5. In the example of FIG. 4, a hexagonal floor mat 25 is used to arrange a pair of partitioning devices 1 facing each other, and a lamp 13 is suspended from each partitioning device 1. On the other hand, in the example of FIG. 5, the hanging rods 11 of the partitioning devices 1 arranged opposite to each other are connected by a V-shaped joint 26, and one lamp 13 is suspended and supported.

(3). Other Embodiments FIGS. 6 and 7 show another embodiment of the holder 16. Of these, the second embodiment shown in FIG. 6A embodies claim 3, and a hook portion 20b is formed in the opening portion of the main body portion 20 as an example of the engaging means. Therefore, even if it is used for a long period of time, the problem of a decrease in holding power due to sagging does not occur, and it is excellent in durability. The holder 16 is manufactured by using a pair of molds that move relative to each other in the axial direction thereof, but is molded with the pair of hook portions 20b separated from each other.

In the third embodiment shown in FIG. 6B, a square cable holding portion 22 is formed on the side of the main body portion 20 opposite to the opening 21. Since the cable holding portion 22 is thinned, a reinforcing rib 24 similar to that shown in FIG. 3D is formed in the intermediate portion in the axial direction.

The fourth embodiment shown in FIG. 6C is a modification of the third embodiment, in which the cable holding portion 22 is formed in a long shape in the circumferential direction, and the positioning rib 29 is provided inside. Since the cable holding portion 22 is about the same thickness as the main body portion 20 and has a long circumferential length, it has excellent durability.

The fifth embodiment shown in FIG. 6D is also a modification of the third embodiment, and by increasing the protruding dimension of the cable holding portion 22, the compatibility with the difference in the thickness of the power cable 15 is improved. By projecting a pair of holding films 30 inside, consideration is given so that the power cable 15 does not shift even if it is thin.

The sixth embodiment shown in FIG. 6E embodies claim 4, and the cable holding portion 22 curved so as to be recessed toward the main body portion 20 is integrated with the back portion of the C-shaped main body portion 20. It is formed in. The cable holding portion 22 is formed in a tongue shape in which one end in the circumferential direction is connected to the main body portion 20 and the other end in the circumferential direction is a free end. Therefore, the cable holding portion 22 can be greatly expanded as shown by the alternate long and short dash line. Therefore, even if the power cable 15 is thick, it can be easily and surely fitted and fixed to the rod-shaped material 17.

In the case of the sixth embodiment, the cable holding portion 22 may be formed in the same cross-sectional shape over the entire length (total height), or as shown in (F) as another example, the cable holding portion 22 is wider than the main body portion 20. It is possible to form the cable holding portion 22 narrowly, or conversely, to form the cable holding portion 22 wider than the main body portion 20.

In each of the above embodiments, the cable holding portion 22 is provided on the opposite side of the main body portion 20 from the opening portion, but in the embodiment shown in FIG. 7, the cable holding portion 22 is provided in the opening portion 21 of the main body portion 20. It is also received in a nearby part.

Of these, in the seventh embodiment shown in FIG. 7A, a cable holding portion 22 facing in the direction opposite to the opening direction of the main body portion 20 is formed on both opening edges 20a of the main body portion 20. On the other hand, in the eighth embodiment shown in FIG. 7B, the cable holding portion 22 is provided at a portion of the main body portion 20 located on the back side from the opening edge 20a. In any of (A) and (B), one end of the cable holding portion 22 is a free end, and the power cable 15 is held and held by the cable holding portion 22 on the outer surface of the main body portion 20. Therefore, it is the embodiment of claim 4.

In the ninth embodiment shown in FIG. 7C, a pair of cable holding portions 22 projecting in the opening direction of the main body portion 20 are provided on the opening edge 20a of the main body portion 20, and the power cable 15 is connected by the cable holding portion 22. It is designed to be pressed and held on the outer peripheral surface of the rod-shaped member 17. Therefore, it becomes the embodiment of claim 1.

In the embodiment shown in FIG. 7, since the main body portion 20 has a simple C shape and has the same thickness over the entire circumference, the holding force of the rod-shaped member 17 is kept constant regardless of the power cable 15. To. Therefore, it has excellent durability. In each example of FIG. 7, a pair of cable holding portions 22 are provided, but it is also possible to provide them only at one of the opening edges 20a.

Although the embodiments of the present invention have been described above, the present invention can be embodied in various ways. Further, the application target is not limited to the partition device, and can be used in various places. For example, it can be used for furniture legs, columns, stands, beams, various frame materials, and the like. It can also be applied to rod-shaped materials such as squares and ellipses (in that case, the main body may be changed according to the shape of the rod-shaped material).

The invention of the present application can be embodied as a holder for a rod-shaped material. Therefore, it can be used industrially.
