JP7579077B2 - Cable holder for rods - Google Patents

Description

This invention relates to a cable holder (which can also be called a cable clip) that holds cables such as power cables and communication cables to rod-shaped materials such as posts and frame materials. Here, rod-shaped materials refer to long, thin members, and include not only solid members but also pipe-shaped members and ropes.

For example, when rod-shaped materials such as frames are used in furniture (fixtures) and indoor/outdoor equipment, cables such as power cables are placed along the rod-shaped materials and held in place by the rod-shaped materials to prevent them from hanging down.

Previously, methods of holding such cables have been proposed, such as a band-type device as disclosed in Patent Documents 1 and 2, a wire-made device as disclosed in Patent Document 3, and a resin holder as disclosed in Patent Documents 4 and 5.

Of these prior art techniques, the holder in Patent Document 4 has a clamping section that elastically holds the pipe material so that it does not slip off the pipe material, and a cable holding section into which the cable is fitted, which are formed in a mutually separated state. In the embodiment shown in Figure 5(a), the clamping section is in a split state, so that it can be fitted into the pipe material from the outside, perpendicular to it.

Patent Document 5 is similar, and has a main body formed in a roughly C-shape in plan view so as to embrace more than half the circumference of the legs that make up the furniture, and a cable holding part protruding from the main body on the side opposite the opening, and the cable holding part has a pair of L-shaped holding pieces that hold the cable by clamping it. The pair of holding pieces are formed in an L-shape in plan view with a base protruding from the main body in a roughly parallel state and hook pieces protruding from the tip of the base in opposing directions, and the pair of holding pieces form a cable storage space, and the cable is pushed into the cable storage space by placing the cable against the hook pieces from the outside and bending the hook pieces.

The holder in Patent Document 5 and the holder in Figure 5(a) in Patent Document 4 are easy to use because they can be attached to the rod-shaped material and the cable to the holder with a single touch. However, in Patent Document 4, the gap between the clamp part and the cable holding part is large, which leaves a gap between the cable and the rod-shaped material, which can be unsightly and can make the cable more likely to get caught on something.

On the other hand, the holder in Patent Document 5 has the advantage that the cable holding portion is close to the rod-shaped material (the leg of the furniture), so the cable can be placed along the outer surface of the rod-shaped material, which looks good and prevents objects from getting caught on it.

In Patent Document 5, when the cable is held in the holder, a pair of hooks extending opposite each other are pushed and bent from the outside by the cable. However, since there is only one pair of hooks and the protruding dimension is not large, there is a problem that a large force is required to push the cable into the space between the pair of holding pieces.

Furthermore, in Patent Document 5, the hook is pushed by the cable and enters the cable holding space, and when the cable leaves the tip of the hook, it returns to its original position due to its elastic restoring force. However, if the cable is thick, there is a concern that the cable will push and bend the hook and hit the main body, and the hook will remain pushed by the cable. In this case, the hook will not be able to return to its original position and deform, and the cable will not be able to be grasped by the pair of holding pieces. Therefore, Patent Document 5 can be said to lack versatility due to the narrow range of cable thicknesses that can be held.

The present invention was made to improve this current situation.

The present invention relates to a holder for holding a cable on a rod-shaped member, typical examples of which are specified in the claims. The invention of claim 1 is as follows:
"A holder for holding a power or communication cable on a rod-shaped material,
a main body portion that partially embraces the rod-shaped material in a longitudinal direction ;
a cable holder formed integrally with the main body;
It has
The main body has a non-loop shape having a pair of opening edges so that the main body can be expanded and deformed to fit over the rod-shaped material , and the width dimension in the axial direction is smaller than the outer diameter .
The cable holding portion is formed in a part of the main body portion so that the cable is sandwiched between the cable holding portion and the rod-shaped material, and the outer circumferential surface of the cable holding portion and the outer circumferential surface of the main body portion are smoothly continuous with each other so as to present an overall C-shape when viewed from the axial direction of the rod-shaped material.
The structure is as follows.

The invention of claim 2 is as follows:
"It has a main body that partially holds the rod-shaped material in a portion of the longitudinal direction , and a cable holding part that is integrally formed with the main body,
The main body has a non-loop shape having a pair of opening edges so that the main body can be expanded and deformed to fit over the rod-shaped material , and the width dimension in the axial direction is smaller than the outer diameter .
the cable holding portion is a cable holder for a rod-shaped material formed on an inner surface side of the main body portion such that a cable is positioned between the cable holding portion and the rod-shaped material,
The cable holding portion is formed by outwardly bulging a portion of the main body opposite the opening, and a pair of tongue-shaped overlapping pieces that overlap the outer surface of the rod-shaped material inside the cable holding portion are formed on the main body so as to extend oppositely from one opening edge side and the other opening edge side of the main body, and a gap is provided between the tips of the pair of tongue-shaped overlapping pieces so that the cable can be inserted and removed.
The structure is as follows.

The invention of claim 3 is an embodiment of claim 1 or 2,
"The main body is designed so that one opening edge and the other opening edge can abut against each other to form a loop-shaped appearance, and the one opening edge and the other opening edge that can abut against each other are formed with engagement parts that mesh with each other to maintain the loop shape."
The structure is as follows.

The invention of claim 4 is based on a different viewpoint from claims 1 and 2,
"A holder for holding a power or communication cable on a rod-shaped material,
The cable holder includes a main body that holds the rod-shaped material, and a cable holder that is integrally formed with the main body.
The main body has a non-loop shape having a pair of opening edges sandwiching an opening so that the main body can be expanded and deformed to fit onto and remove from the rod-shaped material,
the cable holding portion is disposed on the outer surface side of the main body portion so as to hold the cable against the outer peripheral surface of the main body portion on the side opposite the opening, and one end of both ends facing in the circumferential direction is connected to the main body portion and the other end is formed in a tongue shape with a free end, and both ends facing in the circumferential direction of the cable holding portion do not reach the edge of the opening,
A recess into which the cable fits is formed on the rear surface of the main body so as to be recessed toward the opening.
The structure is as follows.

The holder according to the invention of each claim has a non-loop shaped main body, and by expanding the opening against elasticity, the holder can embrace the rod-shaped material from the outside, so that it can be attached to the rod-shaped material with a single touch. It is also easy to remove.

In claims 1 and 2, the cable is sandwiched between the cable holding part and the rod-shaped member, so that the cable can be held in a state overlapping the rod-shaped member simply by overlapping the cable on the inner surface of the cable holding part and then elastically deforming the main body to fit over the rod-shaped member. This allows the cable to be held on the rod-shaped member in an attractive manner, and is also highly adaptable to different cable thicknesses.

In addition, the cable cannot be separated from the rod unless the holder is removed from the rod, so even if an object gets caught on the cable, it will not come off the rod. This means that the cable retention function is also excellent.

When using a holder to hold the cable against the outer surface of the rod-shaped material, it is possible to form an outwardly convex cable holding section on the main body and place the cable in the internal space, but in this case, the cable holding section will be angular, which may result in a poor appearance, and there is also concern that durability will be reduced due to stress being concentrated at the corners.

In this regard, by adopting the configurations of claims 1 and 2 , the outer peripheral surface of the holder can be smoothly curved, so that the holder as a whole has a ring-like appearance that is excellent in appearance and can prevent stress concentration and contribute to improved durability. In addition, since the pair of tongue-shaped overlapping pieces overlap the outer peripheral surface of the rod-shaped material, the contact area between the holder and the rod-shaped material can be increased, contributing to improved holding strength. Furthermore, in claim 2, the cable is positioned between the pair of tongue-shaped overlapping pieces, so the circumferential position of the cable can be accurately determined. In this respect, too, the aesthetic appearance of the cable holding state can be improved.

The main body can hold the rod-shaped material using only elastic restoring force, but if it does so, it may become worn down over long periods of use, causing a decrease in the cable's holding power. However, if the main body is made thicker to increase its holding strength, it becomes difficult to fit it onto the rod-shaped material.

In this regard, when the configuration of claim 3 is adopted, one end of the rod-shaped material engages with the other end while it is being held, maintaining the overall loop (cylindrical) shape, which has the advantage of ensuring high durability without excessive thickness.

The invention of claim 4 provides a cable holding portion on the outside of the main body, so 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 removed while the main body is attached to the rod-shaped material. This allows the cable to be quickly secured in place.

And because the cable holder has a tongue-like shape with one end made free, it can be easily raised with light force by hooking a finger on the free end, etc., which makes it possible to efficiently lock the cable. Also, because the cable holder is raised outward to hold the cable, it can be pushed into the rear part of the main body without any problems, even if the cable is thick. Therefore, it can be used with a wide range of cable thicknesses, making it highly useful.

Next, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, the partition device 1 is used in a holder that holds a power cable for a lighting fixture on the vertical frame material (pillar) of the partition device made of frame material. First, a brief description of the partition device 1 will be given.

(1) Partition device The partition device 1 to which this embodiment is applied has a framework made of metal pipes, and as shown in Figure 2, is equipped with a center support 2, a pair of left and right side support posts 3, upper and lower horizontal frames 4, 5 bent and formed at both the upper and lower ends of the side support 3, and an intermediate horizontal rail 6 fixed by welding at a mid-height position above and below the side support 3.

A rod is fixed to the center support 2 by welding in correspondence with the upper and lower horizontal frames 4, 5 and the middle cross bar 6, and the tips of the upper and lower horizontal frames 4, 5 and the middle cross bar 6 are fitted onto the rod and fixed with screws. The upper and lower horizontal frames 4, 5 and the middle cross bar 6 on the left and right form an obtuse angle in a plan view, but there are also types in which they form a right angle.

The partition device 1 is equipped with a stabilizing plate 7 located in the center when viewed from above, and an adjuster 8 is provided on the lower horizontal frame 5 near the side support 3. In addition, a surface material (screening material) 9 made of a thin material such as fabric or sheet material can be attached to the partition device 1. Multiple partition devices 1 can be connected by joints, and Figure 1 shows two partition devices 1 arranged in opposite directions and connected.

The partition device 1 in this example divides a space (room) into a state that maintains a high degree of openness while also providing a certain degree of closedness, and the space on the inner corner can be used as a work space for people. In this example, a table (desk) 10 is placed on the inner corner of the partition device 1 to enable study or work to be carried out, and a hanging rod 11 is connected to the center support 2 to brightly illuminate the desk surface, and a lamp 13 is hung from a hook 12 attached to the end of the hanging rod 11.

The lower part of the hanging rod 11 is vertical, and the upper part is inclined toward the top of the table 10, with a hook 12 fixed to the upper end (tip). As shown in Figure 3 (A), a rod 14 protrudes downward from the lower end of the hanging rod 11, and the rod 14 is inserted into the center support 2 from above and fixed with a screw (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 held by the hanging rod 11 and the center post 2 with a number of holders 16. Therefore, in this example, the hanging rod 11 and the center post 2 are examples of rod-shaped materials, but it is also possible to fasten the power cable 15 to the upper horizontal frame 4 or the middle crosspiece 6. Hereinafter, the members to which the holders 16 are attached, such as the hanging rod 11 and the center post 2, will be referred to as rod-shaped materials in accordance with the claims, and will be given the reference number 17.

A switch 18 is provided on the top of the center post 2. Furthermore, the lamp 13 is covered with a protective cage 19 made of wire or the like.

(2) Holder The structure of the holder 16 is shown in Figure 3. The holder 16 is an injection molded product made of synthetic resin such as nylon resin, and as shown in Figure 3(B), it has a C-shaped main body 20 so that it can be fitted into and removed from the rod-shaped material 17 in a direction perpendicular to its axis by utilizing elastic deformation. Therefore, the main body 20 surrounds more than half the circumference of the rod-shaped material 17, and the groove width of the opening (constricted portion) 21 is smaller than the outer diameter of the rod-shaped material 17. The end faces of a pair of opening edges 20a on either side of the opening 21 are inclined so as to widen in a V-shape to guide the fitting into the rod-shaped material 17 (they may be in a parallel position).

Then, the cable holding part 22 is formed by expanding and deforming the main body 20 in a direction away from the axis at the part of the main body 20 opposite the opening 21, so that the power cable 15 can be sandwiched and held between the cable holding part 22 and the rod-shaped material 17. Furthermore, a pair of tongue-shaped overlapping pieces 23 that overlap the outer surface of the rod-shaped material 17 are formed at the part of the inner circumference of the main body 20 inside the cable holding part 22, and the power cable 15 is set to overlap the outer surface of the rod-shaped material 17 between the tips of the pair of tongue-shaped overlapping pieces 23.

The cable holding portion 22 and the tongue-shaped overlapping piece 23 are thinner than the main body portion 20, but the thickness can be set as desired. In this embodiment, the outer peripheral surface of the main body portion 20 and the outer peripheral surface of the cable holding portion 22 are smoothly continuous, giving it a simple C-ring appearance that looks good. In addition, when in use, a light elastic restoring force acts on the holder 16 to lightly press down on the power cable 15, but the cable holding portion 22 is continuous with an equal thickness in the circumferential direction, preventing stress from concentrating in a specific area and maintaining high durability.

The axial width (length, height) of the holder 16 can be set arbitrarily, taking into consideration the holding strength of the power cable 15, etc. In Figures 1, 2, and 3(A), the width is only a fraction of the outer diameter, forming a ring shape, but as shown by the dashed line in Figure 3(C), it is also possible to set the width smaller than the outer diameter while greatly expanding the axial width to form a cylindrical shape. In either case, the holder 16 only holds a small portion of the rod-shaped material 17 in the longitudinal direction.

The holder 16 of this embodiment can be used in two ways: first inserting the power cable 15 into the cable holding portion 22 and then pressing the holder 16 against the rod-shaped material 17 to fit it in; or, while holding the power cable 15 against the outer surface of the rod-shaped material 17, pressing the holder 16 against the rod-shaped material 17 to fit it in. Either method can be used.

For example, when attaching the power cable 15 to the center support 2, the power cable 15 overlaps the center support 2 when it is attached to the upper end of the center support 2, so the power cable 15 can be attached by simply pressing the holder 16 against it, without having to hold the power cable 15 with one hand each time. This is an advantage that cannot be achieved in Patent Document 5.

2 shows only one power cable 15, it is also possible to hold multiple power cables 15. The cable holding portion 22 is long in the circumferential direction and has a large deformation margin, so it is highly adaptable to different thicknesses of the power cables 15. It can also be used to hold communication cables such as LAN cables, and it is also possible to hold the power cable 15 and the communication cable together.

As shown as a modified example in FIG. 3(D), it is also possible to form a reinforcing rib 24 extending in the circumferential direction at the axially intermediate position on the outer surface of the cable holding portion 22. Alternatively, as shown by the dashed line 20b in FIG. 3(D), it is also possible to improve the holding function and durability of the power cable 15 while maintaining the ease of fitting and removing it from the rod-shaped material 17 by increasing the axial width (height) at the location of the cable holding portion 22.

The partition device 1 can be used in a variety of layouts. Examples are shown in Figs. 4 and 5. In the example of Fig. 4, a pair of partition devices 1 are arranged facing each other using a hexagonal floor mat 25, and a lamp 13 is suspended from each partition device 1. On the other hand, in the example of Fig. 5, the suspension rods 11 of the partition devices 1 arranged facing each other are connected by a dogleg-shaped joint 26, and one lamp 13 is suspended.

(3) Other embodiments Figure 6 shows other embodiments and reference examples of the holder 16. Among these, the second embodiment shown in Figure 6 (A) is an embodiment of claim 3, and a hook portion 20b is formed as an example of an engagement means at the opening of the main body portion 20. Therefore, even if used for a long period of time, there is no problem of a decrease in holding power due to sagging, and it has excellent durability. The holder 16 is manufactured using a pair of dies that move relative to each other in the axial direction, and is molded in a state in which the pair of hook portions 20b are separated.

In the first reference example shown in Fig. 6(B), a rectangular cable holding portion 22 is formed on the side of the main body 20 opposite the opening 21. Since the cable holding portion 22 is thin-walled, a reinforcing rib 24 similar to that shown in Fig. 3(D) is formed in the axial middle portion.

6(C) is a modified example of the first embodiment , in which the cable holding portion 22 is formed to be long in the circumferential direction and is provided with an internal positioning rib 29. The cable holding portion 22 has approximately the same thickness as the main body portion 20 and is long in the circumferential direction, and therefore has excellent durability.

The third reference example shown in FIG. 6(D) is also a modified example of the first reference example , in which the protruding dimension of the cable holding portion 22 is increased to improve adaptability to differences in thickness of the power cable 15, and a pair of pressing membranes 30 are provided protruding from the inside to prevent the power cable 15 from slipping even if it is thin.

6(E) is an embodiment of claim 4, in which a cable holder 22 curved so as to be recessed toward the main body 20 is integrally formed on the rear surface of the C-shaped main body 20. Therefore, the power cable 15 is held by the cable holder 2 against the rear surface of the main body 20 on the side opposite the opening 21. A recess 20c is formed on the rear surface of the main body 20, recessed toward the opening 21 so that the power cable 15 fits in.
The cable holding portion 22 is formed in a tongue shape with one circumferential end connected to the main body 20 and the other circumferential end as a free end. Therefore, the cable holding portion 22 can be widely expanded as shown by the dashed line. Therefore, even if the power cable 15 is thick, it can be easily and reliably fitted and secured to the rod-shaped material 17. Both ends of the cable holding portion 22 do not reach the opening edge 20a of the main body 20.

In the case of this third embodiment, the cross-sectional shape may be the same over the entire length (total height), or, as shown as another example in (F), the cable holding portion 22 may be formed narrower than the main body portion 20, or conversely, the cable holding portion 22 may be formed wider than the main body portion 20.

Although the embodiment of the present invention has been described above, the present invention can be embodied in many other ways. Furthermore, the application is not limited to partition devices, and the invention can be used in a variety of places. For example, it can be used on furniture legs and posts, stands, beams, and various frame materials. It can also be used on rod-shaped materials such as square or elliptical materials (in this case, the main body can be modified to match the shape of the rod-shaped material).

The present invention can be embodied in a holder for rod-shaped materials. Therefore, it can be used industrially.
