Description

Technical Field

[0001] The present invention relates to a cord holder that is suitably used when guiding a cord raised from the floor into a wiring duct provided on the lower surface of the tabletop.

Background Art

[0002] Conventionally, as this type of cord holder, there is a holder body in which a plurality of unit holders for holding a cord are arranged in the cord extending direction, and a core material made of a metal wire penetrating through the axial center portion of the holder body. A cord holder that holds a plurality of unit holders in a skewered state by the core material has been widely spread (see Non-Patent Document 1).

[0003] However, in the conventional cord holder, both ends of the core material are fixed to the upper and lower ends of the holder body, and the configuration is such that the positions of both fixations cannot be changed. Therefore, once the core material is fixed during assembly, it is difficult to change the tension of the core material after assembly. Thus, there is a problem that not only the tension setting during assembly but also the correction when the tension of the core material decreases due to aging and the tension adjustment of the core material for changing the meandering state of the holder body are difficult.

Mode for Carrying Out the Invention

[0013] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 20.

[0014] As shown in FIGS. 1 to 6, the code holder H in this embodiment is for guiding a plurality of codes E rising from the wiring port Fc of the floor F to the wiring duct I of the table G in a bundled state. Note that the code E is omitted in the drawings other than FIG. 1 to prevent complication of the drawings.

[0015] Generally speaking, this code holder H includes a holder body 2 in which a plurality of unit holders 3 and 4 for holding the code E are arranged in the code extending direction, a common core material 1 penetrating through the axial center portion of the holder body 2 and having one end 1a supported by one end portion 2a of the holder body 2, and a ratchet mechanism 5 as a fixing mechanism for fixing the other end 1b side of the core material 1 to the holder body 2 so that the fixing position can be changed. <Core material 1> (FIGS. 5 to 7, FIG. 10, FIG. 11, FIG. 13) Specifically, the core material 1 is made of synthetic resin introduced into this code holder H instead of the conventional wire, has a flat belt shape, and integrally has a large-diameter portion 11 at the upper end 1a. And as shown in FIG. 13, the tip portion 12 located on the lower end 1b side of the core material 1 has a tapered shape, and an intermittent claw 51 of the ratchet mechanism 5 described later is integrally formed on one side surface 12a thereof. This core material 1 penetrates through the axial center portion of the holder body 2 from above and holds the holder body 2 in a skewered state in a certain form. The core material 1 of this embodiment is loosely fitted in the through holes 31a, 41a, 61a of the holder body 2 so that it can rotate about the axis within a specific angle range.

[0016] Furthermore, since this core material 1 is made of synthetic resin, it is cheaper than conventional wires and has the following characteristics. Based on its material and shape, this core material 1 allows the holder body 2 to bend to a certain extent in the longitudinal direction and both lateral directions of the core material 1. Moreover, since this core material 1 is in the shape of a strip, even though it is made of synthetic resin, it is possible to twist the first and second unit holders 3 and 4 that are connected vertically, and based on its elasticity, it can automatically return to its original position. <Holder body 2> (Figure 2) The holder body 2 comprises a plurality of adjacently arranged first unit holders 3, a second unit holder 4 positioned below the first unit holders 3, and a hook 6 positioned on top of the uppermost first unit holder. In this embodiment, the hook 6 corresponds to one end 2a of the holder body 2. That is, one end 1a (hereinafter referred to as "upper end 1a") of the core material 1, which passes through the plurality of unit holders 3 and 4 and the hook 6, is locked to the hook 6 by the large diameter portion 11, and the other end 1b (hereinafter referred to as "lower end 1b") of the core material 1 is fixed to the second unit holder 4 via a ratchet mechanism 5 so as to be able to change its fixed position. <First unit holder 3> (Figures 5-11) As shown in Figures 7 to 9, the first unit holder 3 includes a hub portion 31 through which the core material 1 passes, and a guide portion 33 that forms a cord insertion space 32 between the hub portion 31 and the guide portion 33, allowing multiple cords E (not shown) to be inserted into the cord insertion space 32.

[0017] In other words, the core material 1 is a flat, strip-shaped object as described above, and the hub portion 31 is cylindrical with a rectangular cross-section through-hole 31a in the axial center through which the core material 1 passes. A positioning projection 31b is provided at the lower end of the hub portion 31, and a positioning recess 31c is formed at the upper end. In addition, a connecting wall 34 extending outward is provided at one location on the outer circumferential surface of the hub portion 31.

[0018] The guide section 33 supports a pair of enclosing walls 33a that curve to surround the hub section 31 at the extended end of the connecting wall 34. That is, each enclosing wall 33a is semi-cylindrical in shape, and the ends of these enclosing walls 33a are butted together via a slit 33b so that they can be separated.

[0019] Between the hub portion 31 and the guide portion 33, a cord insertion space 32 is formed for inserting multiple cords E (not shown). The cord insertion space 32 is a continuous space that forms a C shape in plan view, making it easy to pack multiple cords E into it. The guide portion 33, the connecting wall 34, and the hub portion 31 are integrally molded from synthetic resin, and by elastically deforming the surrounding wall 33a of the guide portion 33, the slit 33b formed between the abutting ends of the surrounding wall 33a can be expanded and contracted. In other words, this unit holder 3 can expand and contract the slit 33b of the guide portion 33 using the elastic deformation of the material, and continuous cords E can be guided in and out of the cord insertion space 32 through the slit 33b. The upper and lower ends of the slit 33b are gradually widened outward to smoothly guide the cords E being inserted and removed. Multiple protrusions 33c are formed on the inner circumference of the guide portion 33 to suppress unnecessary movement of the cord E inserted into the cord insertion space 32. <Second unit holder 4> (Figures 10-13) The second unit holder 4 is located at the bottom of the holder body 2 and includes a hub portion 41 through which the core material 1 passes, and a guide portion 43 that forms a cord insertion space 42 between the hub portion 41 and the hub portion 41. This second unit holder 4 corresponds to the other end 2b of the holder body 2.

[0020] More specifically, a through-hole 41a is formed in the axial portion of the hub portion 41 through which the core material 1 passes, and a positioning recess 41b is formed at the upper end of the hub portion 41. In addition, a connecting wall 44 is provided projecting outward from one location on the outer circumferential surface of the hub portion 41. The guide portion 43 supports a pair of surrounding walls 43a that curve to surround the hub portion 41 at the extended end of this connecting wall 44.

[0021] The second unit holder 4 is located at the bottom of the holder body 2, and a ratchet mechanism 5, which is a fastening mechanism, is provided between the hub portion 41 and the core material 1. The pair of surrounding walls 43a that make up the guide portion 43 each have a flared shape.

[0022] To explain in more detail, each surrounding wall 43a in the second unit holder 4 is a fan-shaped semi-cylindrical body that widens towards the end, and the ends of these surrounding walls 43a are butted together via a slit 43b so that they can be separated. Between the hub portion 41 and the guide portion 43, a cord insertion space 42 is formed for inserting multiple cords E. The cord insertion space 42 is a continuous space that forms a C shape in plan view, making it easy to pack multiple cords E into it. The guide portion 43, the connecting wall 44, and the hub portion are integrally molded from synthetic resin, and by elastically deforming the surrounding wall 43a of the guide portion 43, the slit 43b formed between the abutting ends of the surrounding wall 43a can be expanded and contracted. In other words, the second unit holder 4 can expand and contract the slit 43b of the guide portion 43 using the elastic deformation of the material, and continuous cords E can be guided in and out of the cord insertion space 42 through the slit 43b.

[0023] To put it another way, the second unit holder 4 at the bottom is as follows: The second unit holder 4 located at the bottom of the holder body 2 has a cord inlet 45 at its lower end for introducing multiple cords E raised from the wiring port Fc in the floor F, as shown in Figures 1 and 10 to 13, and a cord outlet 46 for leading out the bundled cords E towards the next unit holder 3, with the cord inlet 45 having an opening shape corresponding to the wiring port Fc.

[0024] In this embodiment, the wiring port Fc of the floor surface F has a linear shape that allows multiple cords E to pass through in a row, as shown in Figure 1. Specifically, this wiring port Fc is formed in a part of the linear gap Fb formed between the OA floor panels Fa that form the raised floor. However, the cord entry port 45 of the second unit holder 4 has a horizontally elongated shape that corresponds to the elongated linear wiring port Fc, as shown in Figure 4.

[0025] Thus, each second unit holder 4 is equipped with a guide portion 43 that encloses the code E passing through its interior, and the code E, guided from the code entry port 45 into the guide portion 43 of the lowest second unit holder 4, is guided into the code insertion space 32 of the next first unit holder 3 without being exposed to the outside.

[0026] However, the opening area of ​​the cord inlet 45 in the second unit holder 4 is set to be larger than the opening area of ​​the cord outlet 46 in the same second unit holder 4. Furthermore, the opening area of ​​the cord outlet 46 in the second unit holder 4 and the opening area of ​​the cord inlet 35 in the next stage first unit holder 3 are set to be the same or approximately the same value (see Figures 10 and 11). <Ratchet mechanism 5> (Figures 13-17) The holder body 2 comprises the second unit holder 4 described above, a plurality of first unit holders 3 arranged in a row on top of the second unit holder 4, and a hook 6, which will be described later, positioned on top of the uppermost first unit holder 3. A flat, strip-shaped core material 1 is passed through a through hole 61a formed in the base end member 61 of the hook 6, through holes 31a formed in the hub portion 31 of each first unit holder 3, and through hole 41a formed in the hub portion 41 of the lowermost second unit holder 4. The large diameter portion 11 formed at the upper end of the core material 1 is locked to the hook 6, and the tip portion 12 of the core material 1 is fastened to the hub portion 41 of the second unit holder 4 via a ratchet mechanism 5, which is a fastening mechanism.

[0027] The ratchet mechanism 5 is configured to allow relative movement between the core material 1 and the holder body 2 in the direction in which the core material 1 is tensioned, and to prohibit relative movement between the core material 1 and the holder body 2 in the direction in which the core material 1 is relaxed. In other words, the ratchet mechanism 5 comprises a plurality of intermittent pawls 51 provided on the core material 1 and a ratchet pawl 52 provided on the second unit holder 4 that selectively engages with the intermittent pawls 51.

[0028] More specifically, as shown in Figures 13 to 17, the ratchet mechanism 5 of this embodiment has multiple intermittent pawls 51 integrally formed on one side surface 12a of the tip portion 12 of the core material 1. As shown in Figures 16 and 17, each intermittent pawl 51 has a most protruding stepped portion 51a and an inclined portion 51b from which the protruding dimension gradually decreases downward. Multiple intermittent pawls 51 are arranged such that the stepped portion 51a of the next intermittent pawl 51 is continuous with the end of the inclined portion 51b of the upper intermittent pawl 51.

[0029] Furthermore, a ratchet pawl 52 is provided within the hub portion 41 of the second unit holder 4 into which the tip portion 12 of the core material 1 is inserted. The ratchet pawl 52 rotates in a direction toward and toward the core material 1 around a resin hinge 53. The ratchet pawl 52 has a pawl body 54 that is rotatably mounted on the hub portion 41 via the resin hinge 53 and elastically biased toward the core material 1. The surface of the pawl body 54 that elastically contacts the core material 1 is provided with an inclined portion 52b whose protruding dimension gradually increases toward the downward, and a stepped portion 52a that is continuous with the lower end of the inclined portion 52b. In the illustrated example, four sets of inclined portions 52b and stepped portions 52a are provided, but at least one set is sufficient.

[0030] However, when an upward pulling force is applied to the core material 1 while one of the ratchet pawls 52 is engaged with the intermittent pawl 51, the pawl body 54 attempts to rotate around the resin hinge 53 in a direction that approaches the core material 1. As a result, the core material 1 is firmly fixed, and the upward pulling motion is prevented.

[0031] On the other hand, when a downward tensile force is applied to the core material 1, as shown in Figure 16, the guiding action of the inclined surface 51b of the intermittent claw 51 causes the claw body 54 to be biased to rotate away from the core material 1 around the resin hinge 53, and the engagement relationship between the intermittent claw 51 and the ratchet claw 52 is released. As a result, the ratchet claw 52 can engage with an upper intermittent claw 51. <Hook 6> (Figures 18-20) The hook 6 of the holder body 2 comprises a base end member 61 positioned on the uppermost unit holder 3, a first hook member 62 extending from the base end member 61 toward the tip (upward in the figure) and folding back in a hook shape midway, and a second hook member 63 extending from the base end member 61 toward the folded end 62a of the first hook member 62. A gap 64 is formed between the folded end 62a of the first hook member 62 and the extended end 63a of the second hook member 63 to allow the object to be hooked K to pass through. The gap 64 is inclined so that the inner end 64b is closer to the base end member 61 than the outer end 64c. In other words, the aforementioned gap 64 is inclined so that the opening width becomes smaller when the folded end 62a of the first hook member 62 is elastically displaced outward (outward in the figure).

[0032] This hook 6 has the inner surface 62b of the folded end 62a of the first hook member 62 and the inner surface 63b of the extended end 63a of the second hook member 63 connected in a substantially flush manner, and the gap 64 is formed such that the opening width on the outer end 64c side is larger than the opening width on the inner end 64b side.

[0033] This hook 6 is attached to the bottom wall Ia of the wiring duct I, which is located on the underside of the top plate J. The object to which this hook 6 attaches, K, is a strip-shaped piece formed by reusing a portion of the bottom wall Ia of the wiring duct I. Specifically, a pair of through-windows Ib are drilled into the bottom wall Ia, and the strip-shaped portion formed between these through-windows Ib is used as the object to which this hook 6 attaches, K.

[0034] As shown in Figures 19 and 20, the base end member 61 of the hook 6 is connected to the uppermost first unit holder 3 of the holder body 2, and can be said to be provided at the upper end (one end 2a) of the holder body 2. This base end member 61 has a through hole 61a in its axial portion for passing the core material 1 through, and the large diameter portion 11 of the core material 1 can be locked at the upward opening end surface 61b of the through hole 61a. In addition, a canopy portion 61c is provided above the upward opening end surface 61b of the base end member 61 to prevent the core material 1 from coming out upward, thereby preventing the core material 1 from coming out straight upward. A guide inclined surface 61d is formed on the upper surface of the canopy portion 61c to prevent the large diameter portion 11 of the core material 1 from getting caught on the canopy portion 61c just before the core material 1 is fully inserted into the through hole 61a.

[0035] The upper end of the base member 61 is integrally provided with the aforementioned first and second hook members 62 and 63, while the lower end is provided with a projection 61e that loosely fits into the positioning recess 31c of the first unit holder 3 located in the lower section (see Figure 19). <Assembly Instructions> Here, we will explain the assembly procedure for this cord holder H. First, the core material 1 is sequentially inserted from the lower end 1b side through the through hole 61a formed in the base end member 61 of the hook 6, the through hole 31a formed in the hub portion 31 of each first unit holder 3, and the through hole 41a formed in the hub portion 41 of the second unit holder 4. Through this process, the hook 6, the multiple first unit holders 3, and the second unit holders 4 are held together in a skewer-like state by the common core material 1.

[0036] In this process, the large-diameter portion 11 formed on the upper end 1a of the core material 1 is guided by the guide inclined surface 61d of the hook 6, temporarily retracted to the side, and then locked onto the upward-facing open end surface 61b of the hook 6, thereby preventing the core material 1 from moving downward. On the other hand, the tip portion 12 located on the lower end 1b side of the core material 1 is inserted into the through hole 41a of the hub portion 41 of the second unit holder 4 located at the lowest stage, and is automatically fixed to the second unit holder 4 by the action of the ratchet mechanism 5 incorporated within the hub portion 41.

[0037] The assembly can be completed by passing the core material 1 through the holder body 2 using the above procedure. However, the fixing position of the tip 12 of the core material 1 relative to the holder body 2 can be appropriately selected based on the degree of downward pulling on the core material 1 just before the completion of assembly, and can also be changed after the completion of assembly by further pulling on the core material 1 downward. In other words, this ratchet mechanism 5 can select which intermittent pawl 51 of the core material 1 the ratchet pawl 52 on the holder body 2 side will engage with, solely based on the degree of downward pulling on the core material 1. When the ratchet pawl 52 is engaged with the upper intermittent pawl 51, a relatively high tension is applied to the core material 1, and when the ratchet pawl 52 is engaged with the lower intermittent pawl 51, a relatively low tension is applied to the core material 1.

[0038] However, when the tension of the core material 1 is relatively low, the engagement between the positioning projections 31b and the positioning recesses 31c and 41b, respectively, between the first unit holder 3 and the second unit holder 4 becomes looser, making it possible to bend the cord holder H relatively significantly. On the other hand, when the tension of the core material 1 is relatively high, the engagement between the aforementioned positioning projections 31b and the positioning recesses 31c and 41b becomes tighter, which is suitable for cases where it is desirable to maintain the entire cord holder H in a nearly straight state.

[0039] Changing the fixed position can be done simply by pulling the tip 12 of the core material 1 downwards, making it easy to assemble the core material 1 and adjust its tension. To remove the core material 1 from the holder body 2 or to reset the tension of the core material 1, the ratchet pawl 52 can be temporarily retracted away from the core material 1 using a tool such as a screwdriver (not shown). <Effects of Code Holder H> With a cord holder H of this configuration, the tip 12 of the core material 1 is fixed to the holder body 2 via a ratchet mechanism 5 so that its fixed position can be changed, making it easy to assemble the core material 1 and adjust the tension.

[0040] In other words, with this configuration, the assembly of the core material 1 to the holder body 2 is completed by passing the tip portion 12 of the core material 1 through the hub portion 41 of the second unit holder 4 and engaging the ratchet pawl 52 with one of the intermittent pawls 51 formed on the tip portion 12.

[0041] While the cord holder H can certainly be used as a finished product in this state, it is also possible to further adjust the tension of the core material 1 during assembly. In that case, first, the ratchet pawl 52 on the holder body 2 side is engaged with the intermittent pawl 51 located lower on the tip 12 of the core material 1. Next, when the tip 12 of the core material 1 is pulled downward relative to the holder body 2, the ratchet pawl 52 will sequentially engage with the intermittent pawls 51 located higher up, and the tension of the core material 1 will increase in stages. Therefore, when the pulling of the tip 12 is stopped when the tension of the core material 1 is appropriate, the core material 1 will be fixed to the holder body 2, and the core material 1 can be attached to the holder body 2 while maintaining the desired tension.

[0042] Even if the tension of the core material 1 decreases due to aging or other factors, simply pulling the tip 12 of the core material 1 against the holder body 2 will relatively change the fixing position of the core material 1 relative to the holder body 2. Therefore, the tension of the core material 1 can be easily and appropriately adjusted.

[0043] Furthermore, since the core material 1 is made into a flat, strip-shaped piece, it becomes easy to form a relatively wide intermittent pawl 51 at its tip 12 that the ratchet pawl 52 can easily engage with. Moreover, since the core material 1 is made of synthetic resin, the intermittent pawl 51 can be formed on the core material 1 without increasing the number of parts.

[0044] Furthermore, since the ratchet pawl 52 that engages with the intermittent pawl 51 is integrally molded with the hub portion 41 of the second unit holder 4 via a resin hinge 53, this also allows for a reasonable reduction in manufacturing and assembly man-hours.

[0045] Specifically, the second unit holder 4 positioned at the bottom has a hub portion 41 that penetrates the core material 1 and a guide portion 43 that forms a cord insertion space 42 between the hub portion 41 and the guide portion 43, and the ratchet pawl 52 is integrally provided with the hub portion 41 via a resin hinge 53. Therefore, it is possible to manufacture the second unit holder 4 and the ratchet pawl 52 as a single part by integral molding of synthetic resin. As a result, the man-hours required for part manufacturing can be significantly reduced. <Other Embodiments> Furthermore, the present invention is not limited to the embodiments described above, and various modifications are possible.

[0046] For example, the number of unit holders constituting the holder body is not limited to that shown in the illustration, and their shape may also be other as long as they are held by the core material and can guide the cord.

[0047] Furthermore, the core material is not limited to synthetic resin, nor is its shape limited to a flat, strip-like form. However, adopting such a form allows for the incorporation of a ratchet mechanism without increasing the number of parts, as mentioned above.

[0048] Furthermore, in the illustrated embodiment, the fastening mechanism is described as a ratchet mechanism configured to allow relative movement of the core material 1 with respect to the holder body 2 in only one direction, allowing relative movement in the direction that increases the tension of the core material 1 and prohibiting relative movement in the direction that decreases the tension. However, the fastening mechanism is not limited to the ratchet mechanism described above, and various modifications are possible, for example, by providing multiple latching parts on either the core material or the holder body, and providing the other with a hook claw or the like that can selectively latch onto any of the locking parts.

[0049] Furthermore, various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
