Description

[Technical Field]

[0001] The present invention relates to a wire dressing tool for a wiring duct that prevents electric wires from spilling out of an upper opening of the wiring duct. [Background technology]

[0002] As shown in FIG. 6 of Patent Document 1, it is known that a wiring duct used for indoor wiring, etc., is configured with a long duct body with a U-shaped cross section and a long duct cover that closes the upper opening. The duct body is composed of a bottom wall and side walls and has a U-shaped cross section with an upper opening, and a hook-shaped body-side engaging portion is formed at the upper end of the side wall. A number of rectangular windows for guiding electric wires are arranged side by side on both side walls. The duct cover is composed of a cover body that serves as a top plate that closes the upper opening, and cover-side engaging portions are formed at both ends of the cover body in the width direction to engage with the body-side engaging portions. With a wiring duct configured as described above, the duct cover can be attached to the duct body by aligning the duct cover on the duct body and then pressing the duct cover against the duct body from above to engage the body-side engaging portions and the cover-side engaging portions. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-172717 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described wiring duct, if the electric wires housed within the duct body spill over the upper opening and become lodged at the top of the side wall, it becomes impossible to engage the body-side engaging portion with the cover-side engaging portion, making it impossible to attach the duct cover to the duct body. A widely known method to prevent this is to use a tool such as a screwdriver to push down the electric wires housed within the duct body prior to attaching the duct cover. More specifically, a widely known method involves inserting a screwdriver through a window formed in the left and right side walls, installing the screwdriver so that it penetrates the duct body, and then depressing the shaft of the screwdriver to push down the electric wires housed within the duct body and prevent them from lifting up. However, this method of using a tool such as a screwdriver to push down the electric wires may cause the screwdriver to rise due to the repulsive force of the electric wires (lift-up force) if the worker releases the screwdriver. In the worst case scenario, the screwdriver may slip out of the window, causing the held-down electric wires to spill out of the duct body again, making it unreliable and unreliable. Furthermore, with the above method, the driver is always removed once the duct cover has been attached to the duct body, so if the duct cover is removed during maintenance or inspection, there is a risk that the wires will spill out of the duct body again.

[0005] An object of the present invention is to provide a wire dressing tool for a wiring duct that can reliably prevent electric wires housed in a duct body from spilling out beyond the upper opening. [Means for solving the problem]

[0006] The present invention relates to a wire arranging tool 15 that is attached to a wiring duct 1 to prevent the electric wires housed within the wiring duct 1 from spilling out. The wiring duct 1 to be attached includes a duct body 5 having a U-shaped cross section, a bottom wall 2, and a pair of front and rear side walls 3, 3, with an upper opening 4, and a duct cover 6 that is attached to the duct body 5 to close the upper opening 4. Each side wall 3 has vertically elongated rectangular windows 10 arranged side by side in the left-right direction. The wire arranging tool 15 includes a base portion 16 disposed outside the side wall 3, a locking portion 18 that secures the base portion 16 to the side wall 3, and a shaft portion 17 that extends in the front-rear direction from the base portion 16. The shaft portion 17 is inserted into the duct body 5 through the window 10, and the base portion 16 is secured to the side wall 3 by the locking portion 18, so that the shaft portion 17 is installed between the front and rear side walls 3, 3.

[0007] The locking portion 18 includes a pair of left and right arms 22 extending in the front-rear direction from the base portion 16 and elastically deformable so as to approach each other, and a locking claw 23 provided at the tip of each arm 22 for engaging with the inner surface of the side wall 3 along the edge of the window 10. A shaft portion 17 is formed between the arms 22 in the left-right direction.

[0008] When the insertion direction of the shaft portion 17 is defined as rearward, the arm portion 22 is composed of a first piece 22a that extends forward from the rear end of the base portion 16 and enters into the base portion 16, and a second piece 22b that extends rearward from the front end of the first piece 22a and protrudes rearward beyond the rear end of the base portion 16, and a locking claw portion 23 is formed at the rear end of the second piece 22b.

[0009] The width W of the shaft portion 17 in the left-right direction is set smaller than the thickness T1 in the up-down direction.

[0010] An operation knob portion 19 that is thinner than the base portion 16 is formed on the outer side of the base portion 16 in the front-rear direction. [Effects of the Invention]

[0011] A wire arranging tool for wiring ducts (hereinafter simply referred to as "wire arranging tool") 15 according to the present invention includes a base portion 16 disposed outside the side wall 3 of the duct main body 5, a locking portion 18 for attaching and fixing the base portion 16 to the side wall 3, and a shaft portion 17 extending in the front-to-rear direction from the base portion 16. The wire arranging tool 15 according to the present invention is configured so that the shaft portion 17 is installed between the front and rear side walls 3 by inserting the shaft portion 17 into the duct main body 5 through a window 10 formed in the side wall 3 and then attaching and fixing the base portion 16 to the side wall 3 with the locking portion 18. With the wire arranging tool 15 according to the present invention configured as described above, after accommodating a plurality of electric wires 8 within the duct main body 5, the shaft portion 17 can be inserted into the duct main body 5 through the window 10 so as to be positioned above the electric wires 8, and then the base portion 16 can be attached and fixed to the side wall 3 with the locking portion 18, thereby disposing the shaft portion 17 above the electric wires 8. Therefore, by using the wire arranging tool 15 of the present invention, the shaft portion 17 disposed on the wires 8 can prevent the wires 8 housed in the duct body 5 from floating up, thereby reliably preventing the wires 8 from spilling out of the duct body 5 beyond the upper opening 4. Furthermore, according to the present invention, the wire arranging tool 15 can be attached to the duct body 5 by a simple operation of inserting the shaft portion 17 into the duct body 5 through the window 10 and attaching and fixing the base portion 16 to the side wall 3 with the locking portion 18, thereby enabling the wire arranging tool 15 to be quickly attached to the duct body 5 with a single touch. In addition, because the wires 8 do not spill out beyond the upper opening 4, the attachment of the cover 6 to the duct body 5 can be easily and reliably performed. Furthermore, if the wire dressing tool 15 is left attached without being removed even after the cover 6 is attached, the wires 8 will not spill out of the duct body 5 even if the cover 6 is removed during subsequent maintenance or inspection, and the work of reattaching the cover 6 after maintenance or inspection can be easily and reliably carried out.

[0012] The locking portion 18 is provided with a pair of left and right arms 22 that extend in the front-to-rear direction from the base portion 16 and are elastically deformable in directions approaching each other, and a locking claw portion 23 that is provided at the end of each arm 22 and engages with the inner surface of the side wall 3 relating to the edge of the window 10.When the shaft portion 17 is formed between the left and right arms 22, the left and right arms 22 and the shaft portion 17 can be arranged side by side in the left and right direction, thereby preventing misalignment between the engagement position of the locking portion 18 with respect to the window 10 and the insertion position of the shaft portion 17 with respect to the window 10, and making it easy to insert the shaft portion 17 into the appropriate position and attach the wire arrangement tool 15.

[0013] Generally, the thickness of the side wall 3 of the duct body 5 to which the wire dresser 15 is attached is thin, approximately 2 mm or less. Therefore, for example, if the arm portion 22 is extended rearward from the rear end of the base portion 16, the length of the arm portion 22 is extremely short, approximately the same as the thickness of the side wall 3, that is, 2 mm or less, making it difficult to impart sufficient elastic deformability to the arm portion 22. In contrast, as in the present invention, the locking portion 18 is composed of a first piece 22a extending forward from the rear end of the base portion 16 so as to enter the base portion 16, and a second piece 22b extending rearward from the tip of the first piece 22a and protruding rearward beyond the rear end of the base portion 16. This allows the length of the arm portion 22 to be longer than in a configuration in which the arm portion 22 is extended rearward from the rear end of the base portion 16, thereby imparting sufficient elastic deformability to the arm portion 22.

[0014] Generally, the lateral width of the window 10 opened in the side wall 3 is small, at 10 mm or less. Therefore, when the left and right arm portions 22 and the shaft portion 17 are arranged side by side in the lateral direction as described above, it is difficult to ensure a space between the shaft portion 17 and the arm portion 22 that allows elastic deformation of the arm portion 22. In contrast, if the lateral width dimension W of the shaft portion 17 is set smaller than the vertical thickness dimension T1 as in the present invention, the lateral width dimension W of the shaft portion 17 can be made smaller, making it easier to ensure a space between the shaft portion 17 and the arm portion 22 that allows elastic deformation of the arm portion 22. Furthermore, if the lateral width dimension W of the shaft portion 17 is set smaller than the vertical thickness dimension T1, in other words, if the vertical thickness dimension T1 of the shaft portion 17 is larger than the lateral width dimension W, the rigidity of the shaft portion 17 in the vertical direction can be improved, and deformation of the shaft portion 17 due to the lift-up force of the electric wire 8 can be prevented.

[0015] If a knob portion 19 thinner than the base portion 16 is formed on the outer side of the base portion 16 in the front-to-rear direction, the worker can proceed with the installation work of the wire arranging tool 15 while holding the knob portion 19 with the fingertips. Furthermore, by rotating the knob portion 19 to a vertical position, the locking portion 18 can be set to a vertical position in which both arm portions 22 are aligned in the vertical direction, thereby releasing the locking state of the locking portion 18 with respect to the side wall 3, and the wire arranging tool 15 can be removed from the duct main body 5. Therefore, the wire arranging tool 15 can be removed from the duct main body 5 by the simple operation of simply rotating the knob portion 19. If the knob portion 19 is formed thinner than the base portion 16, the knob portion 19 can be rotated with a smaller movement, making the removal work of the wire arranging tool 15 easier.

[0017] 1 to 7 show an embodiment of a wiring duct wire arranging tool (hereinafter referred to as "wire arranging tool") according to the present invention. In this embodiment, the terms "front, back, left, right, top, bottom" refer to the crossed arrows shown in Figs. 1 and 2 and the notations for "front, back, left, right, top, bottom" near the crossed arrows.

[0018] As shown in FIGS. 2 and 3 , the wiring duct 1 to which the wire arranging tool of this embodiment is attached comprises a duct body 5 having a U-shaped cross section and an upper opening 4, which includes a bottom wall 2 and a pair of front and rear side walls 3 and 3, and a duct cover 6 (see FIG. 3 ) that closes the upper opening 4 of the duct body 5. Both the duct body 5 and the duct cover 6 are made of a long, rectangular resin material that is elongated in the left-right direction. As shown in FIGS. 1 and 3 , a number of electric wires 8 are housed within a storage space 7 defined by the bottom wall 2 and the side walls 3 and 3 of the duct body 5. As shown in FIG. 2 , a number of rectangular windows 10 are arranged side by side on the front and rear side walls 3 and 3 of the duct body 5 for guiding the electric wires 8. The front and rear side walls 3 and 3 of the duct body 5 each have a hook-shaped body-side engaging portion 11 formed at the upper end thereof, and the cover body 12, which serves as the top plate of the cover 6, has a cover-side engaging portion 13 formed at both front-rear ends thereof that engage with the body-side engaging portion 11 (see FIG. 3 ). In the wiring duct 1 configured as described above, the cover 6 can be attached to the duct body 5 by aligning the cover 6 on the duct body 5 and then pressing the cover 6 against the duct body 5 from above, thereby engaging the body-side engaging portions 11 and the cover-side engaging portions 13. In this embodiment, the thickness of the side wall 3 in the front-to-rear direction is approximately 2 mm. The opening dimension of the window 10 in the left-to-right direction is approximately 10 mm.

[0019] 1 to 4, the wire arranging tool 15 is attached to the duct body 5 of the wiring duct 1 for the purpose of preventing the electric wires 8 housed in the housing space 7 from floating up and spilling out of the upper opening 4, and is composed of a square block-shaped base portion 16, a shaft portion 17 protruding rearward from the center of the base portion 16 in the left-right direction, a locking portion 18 for attaching the base portion 16 to the side wall 3, and a knob portion 19 formed thinner than the base portion 16. The wire arranging tool 15 is a resin molded product in which all of these portions are integrally formed.

[0020] As shown in FIG. 1, when the base portion 16 is attached to the front sidewall 3A (3), it is disposed forward of the sidewall 3A, i.e., outward of the sidewall 3A, and a slit 20 that is shaped like a figure eight in a plan view is formed inside the base portion 16. As shown in FIG. 4, the locking portion 18 includes a pair of left and right arms 22 extending from the base portion 16 and a locking claw 23 provided at the rear end (protrusion) of each arm 22. The locking claw 23 engages with the inner surface of the sidewall 3A, which is the edge of the window 10, i.e., the opening edge. The arm 22 is composed of a first piece 22a that extends forward from the rear end of the base portion 16 and enters the base portion 16, and a second piece 22b that extends rearward from the protrusion of the first piece 22a and protrudes rearward beyond the rear end of the base portion 16. The connecting portion between the first piece 22a and the second piece 22b is a curved portion 22c that is partially arc-shaped.

[0021] As shown in FIG. 1, a rectangular shaft portion 17 protrudes rearward from the center of the base portion 16 in the left-right direction. As shown in FIG. 3, the shaft portion 17 is inserted through a window 10 opened in the front side wall 3A and is disposed above the electric wires 8 accommodated in the accommodation space 7 when the wire arranging tool 15 is attached to the duct body 5, thereby preventing the electric wires 8 from floating up or spilling out beyond the upper opening 4. The length of the shaft portion 17 is set such that, when the wire arranging tool 15 is attached to the duct body 5, its rear end protrudes slightly rearward beyond the window 10 in the rear side wall 3B(3). As shown in FIG. 7, the width W of the shaft portion 17 in the left-right direction is set smaller than the thickness T1 in the up-down direction.

[0022] As shown in Fig. 4, within base portion 16, a slit 20 defines a space between the base end of shaft portion 17 and the base end of arm portion 22. A gap 24 is formed between shaft portion 17 and arm portion 22 in front of base portion 16, and is continuous with slit 20 to allow elastic deformation of arm portion 22. As shown in Figs. 2 and 3, the thickness dimension in the vertical direction of base portion 16 and locking portion 18 is the same as thickness dimension T1 in the vertical direction of shaft portion 17.

[0023] A rectangular, flat operating knob 19 is formed at the front end of the base 16. As shown in Fig. 2, the knob 19 protrudes forward from the center of the base 16 in the vertical direction, and its vertical thickness T2 is smaller than the vertical thickness T1 of the base 16 (see Fig. 7).

[0024] To attach the wire arranging tool 15 configured as described above to the duct body 5, first, as shown in FIG. 5, the worker inserts the shaft portion 17 into the duct body 5 through the window 10 in the front side wall 3A. At this time, the shaft portion 17 is positioned higher than all of the wires 8 housed in the duct body 5. Next, the locking claws 23 of the engaging portion 18 are advanced into the window 10, and the locking claws 23 engage with the inner surface of the side wall 3A that is adjacent to the opening edge of the window 10 (see FIGS. 1, 3, and 4). Specifically, from a state in which the rear end edge of the locking claws 23 is in contact with the opening edge on the front side of the side wall 3A, the entire wire arranging tool 15 is pushed rearward, thereby elastically deforming the left and right arms 22 of the engaging portion 18 in directions that bring them closer to each other, and allowing the locking claws 23 to advance into the window 10. From this state, if the wire arranging tool 15 is further pushed rearward, the locking claws 23 climb over the side wall 3A and the arms 22 return to their normal positions, allowing the locking claws 23 to engage with the inner surface of the side wall 3A. By engaging the locking claws 23 with the side wall 3A in this manner, the base 16 is attached and fixed to the side wall 3A by the engaging portions 18, thereby placing the wire arranging tool 15 in an attached state. In this attached state, the shaft 17 extends cantilevered rearward from the base 16. In addition, in the attached state, the shaft 17 is positioned above the wires 8 and is bridged between the front and rear side walls 3A and 3B.

[0025] To remove the wire arranging tool 15 from the duct body 5 in the above-described attached state, first, as shown by the phantom lines in Figure 6, the operator grasps the knob 19 with his or her fingertips and rotates the knob 19 from a horizontal position to a vertical position. This twists the base 16, allowing the locking portion 18 to assume a vertical position with both arms 22 aligned vertically, thereby releasing the locking portion 18 from its engagement with the opening edge of the side wall 3A. Next, the wire arranging tool 15 is pulled forward, and the shaft 17 is pulled out through the window 10 in the front side wall 3A. By following the above procedure, the wire arranging tool 15 can be separated and removed from the duct body 5.

[0026] As described above, the wire arranging tool 15 according to this embodiment includes a base portion 16 disposed outward (forward) of the front side wall 3A of the duct main body 5, a locking portion 18 for attaching and fixing the base portion 16 to the side wall 3A, and a shaft portion 17 extending in the front-rear direction from the base portion 16. The wire arranging tool 15 according to this embodiment is configured so that the shaft portion 17 is installed between the front and rear side walls 3A and 3B by inserting the shaft portion 17 into the duct main body 5 through the window 10 in the side wall 3A(3) and then attaching and fixing the base portion 16 to the side wall 3A with the locking portion 18. With the wire arranging tool 15 according to this embodiment configured as described above, after accommodating multiple electric wires 8 within the duct main body 5, the shaft portion 17 can be inserted into the duct main body 5 through the window 10 so as to be positioned above the multiple electric wires 8, and then the base portion 16 can be attached and fixed to the side wall 3A with the locking portion 18, thereby disposing the shaft portion 17 above the electric wires 8. Therefore, by using this wire arranging tool 15, the shaft portion 17 can suppress the lifting of the wires 8, thereby reliably preventing the wires 8 housed in the duct body 5 from spilling out beyond the upper opening 4. Furthermore, the wire arranging tool 15 can be attached to the duct body 5 by simply inserting the shaft portion 17 into the duct body 5 through the window 10 and fastening the base portion 16 to the side wall 3A with the locking portion 18, allowing for a quick and easy installation. Additionally, because the wires 8 do not spill out beyond the upper opening 4, the installation of the cover 6 on the duct body 5 can be easily and reliably performed. Furthermore, if the wire arranging tool 15 is left attached after the cover 6 is installed, the wires 8 will not spill out again from the duct body 5 even if the cover 6 is removed for subsequent maintenance or inspection, and the installation of the cover 6 after maintenance or inspection can be easily and reliably performed.

[0027] The locking portion 18 comprises a pair of left and right arms 22 extending in the front-to-rear direction from the base portion 16 and elastically deformable in the left-to-right direction, that is, directions in which they approach each other, and a locking claw 23 provided at the tip (rear end) of each arm 22 for engaging with the inner surface of the side wall 3A relating to the opening edge of the window 10, and the shaft portion 17 is formed between the left and right arms 22, so that the left and right arms 22 and the shaft portion 17 can be arranged side by side in the left-to-right direction. This prevents misalignment between the engagement position of the locking portion 18 with respect to the window 10 and the insertion position of the shaft portion 17 with respect to the window 10, making it easier to insert the shaft portion 17 into a more appropriate position and attach the wire arranging tool 15.

[0028] In this embodiment, the thickness of the side wall 3A of the duct body 5 to which the wire dresser 15 is attached is as thin as 2 mm. Therefore, for example, if the arm portion 22 were extended rearward from the rear end of the base portion 16, the length of the arm portion 22 would be extremely short, about 2 mm, which is approximately the same as the thickness of the side wall 3A, making it difficult to impart sufficient elastic deformability to the arm portion 22. In contrast, as in this embodiment, the locking portion 18 is composed of a first piece 22a extending forward from the rear end of the base portion 16 so as to enter the base portion 16, and a second piece 22b extending rearward from the tip (front end) of the first piece 22a and protruding rearward beyond the front end of the base portion 16. This allows the length of the arm portion 22 to be longer than in a configuration in which the arm portion 22 extends rearward from the rear end of the base portion 16, thereby imparting sufficient elastic deformability to the arm portion 22.

[0029] Because the left-right width of the window 10 opened in the side wall 3 is as small as 10 mm, when the left and right arm portions 22 and the shaft portion 17 are arranged side by side in the left-right direction as described above, it is difficult to ensure a space between the shaft portion 17 and the arm portion 22 that allows elastic deformation of the arm portion 22. In contrast, in this embodiment, the left-right width dimension W of the shaft portion 17 is set to be smaller than the up-down thickness dimension T1, so that the left-right width dimension W of the shaft portion 17 can be made smaller and a space that allows elastic deformation of the arm portion 22 can be ensured between the shaft portion 17 and the arm portion 22. Furthermore, because the left-right width dimension W of the shaft portion 17 is set to be smaller than the up-down thickness dimension T1, in other words, the up-down thickness dimension T1 of the shaft portion 17 is larger than the left-right width dimension W, the rigidity of the shaft portion 17 in the up-down direction can be improved, and deformation of the shaft portion 17 due to the lift-up acting force of the electric wire 8 can be more reliably prevented.

[0030] Since the knob portion 19 is formed on the outer side of the base portion 16 in the front-to-rear direction, the worker can grip the knob portion 19 with his / her fingertips while installing the wire arranging tool 15. Furthermore, by rotating the knob portion 19 to a vertical position, the locking portion 18 is placed in a vertical position with both arms 22 aligned vertically, thereby releasing the locking state of the locking portion 18 relative to the side wall 3A, and the wire arranging tool 15 can be removed from the duct main body 5. As described above, according to this embodiment, the wire arranging tool 15 can be removed from the duct main body 5 by a simple operation of simply rotating the knob portion 19. Since the knob portion 19 is formed to be thinner than the base portion 16, the knob portion 19 can be rotated with a smaller movement. Therefore, the wire arranging tool 15 can be more easily removed from the duct main body 5.

[0031] The length dimension of the shaft portion 17 in the front-to-rear direction is not limited to that shown in the above embodiment, and the key point is that it should be long enough to protrude from the rear side wall 3B when the wire dresser 15 is attached to the front side wall 3A of the duct body 5. The shape of the shaft portion 17 is not limited to the rectangular shaft shape shown in the above embodiment, and may be a round shaft shape. [Explanation of symbols]
