DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a main part of a work table 1 to which a wiring duct device according to the present invention is applied. A support 2 that is separated from the left and right, a top plate 4 that is attached to the front and rear of the support 2 via a bracket 3, a wiring duct 5 that is attached between the top plates 4, and an upper surface of the wiring duct 5. The wiring duct cover 6 is mainly composed of the covering.
[0010]
As shown in FIGS. 2 and 3, the support column 2 is formed by bending a steel material or the like, and a base piece 2c serving as a side wall and a first extending in the direction of the support column 2 facing from both sides of the base piece 2c. A wide part composed of the front and rear pieces 2a, an intermediate piece 2e extending inwardly from the front ends of the first front and rear pieces 2a and extending inward substantially in parallel to the base piece 2c, and extends from the front ends of these intermediate pieces 2e in the direction of the struts 2 facing each other. The inside composed of the second front and rear pieces 2b and the narrow portion made up of the reinforcing pieces 2d folded back inward from the tips of the second front and rear pieces 2b so that the inside is hollow and has a substantially convex shape. Is formed.
[0011]
The first front / rear piece 2a and the second front / rear piece 2b are provided with a plurality of locking holes 7 and 8 that are engageable with locking claws formed in the bracket 3 and the wiring duct 5 in the vertical direction.
[0012]
The base piece 2 c is provided with a large wiring hole 9 (see FIG. 1), and the cords C can be inserted into the wiring duct 5 through the wiring holes 9. It is like that.
[0013]
As shown in FIGS. 2 to 4, the wiring duct 5 has a substantially L-shaped cross section from a bottom plate 10 a and a side plate 10 b that are approximately the same size as the separation width of the reinforcing pieces 2 d in both struts 2 facing in the left-right width. It is comprised by the pair of frame members 10 and 10 formed in this.
[0014]
Bending pieces 10c that are bent inward are provided at the upper end side of the side plate 10b in each frame member 10, and locking claws that can be engaged with the front and rear locking holes 8 are provided at the left and right ends thereof. A locking piece 10d formed inwardly with 10e is provided so as to extend downward.
[0015]
The engaging claw 10e of each frame member 10 is engaged with the engaging hole 8 at the same height position on the second front and rear piece 2b of the support column 2 from the front and rear, respectively, so that the upper part is opened with a substantially U-shaped cross section. The formed wiring duct 5 is formed, and the cords C can be accommodated therein.
[0016]
The wiring duct cover 6 has a left-right width that is substantially the same as the spacing between the intermediate pieces 2e of the left and right support columns 2, and a left and right end portion of the wiring duct cover 6 that can be fitted into a narrow portion of the support column 2. A notch 6d is formed.
[0017]
Since a bent piece 6b that is bent upward is formed at the lower end of the bent piece 6a that is bent downward from the front and rear edges of the wiring duct cover 6, the wiring duct cover 6 is connected between the folded pieces 6b. The upper edge of the side plate 10b of the duct 5 is placed on the upper part of the wiring duct 5 so as to sandwich the upper edge.
[0018]
At this time, the left and right cutouts 6d of the wiring duct cover 6 are fitted into the narrow portion of the support column 2, so that the back and forth horizontal shaking with respect to the wiring duct 5 is suppressed.
[0019]
In FIG. 4, reference numeral 11 denotes a locking member made of a metal member. The locking portion 11 a that can be engaged with the front and rear locking holes 8 at the left and right ends, and the upper surface of the wiring duct cover 6 at the time of mounting. The contact piece 11b is formed in a substantially U shape when viewed from above.
[0020]
Since the locking member 11 is integrally attached to the column 2 by engaging the locking portion 11a with the locking hole 8 of the column 2, the upper and lower sides of the wiring duct cover 6 are caused by the surface pressure of the contact piece 11b. Shaking and upward deviation are prevented.
[0021]
The bracket 3 is provided with a plurality of locking claws 3a that can be engaged with the locking holes 8 at the rear end in a vertical direction, and is folded inward, and an insertion hole 3b is formed in the bent piece.
[0022]
The bracket 3 can be attached to the column 2 by engaging its locking claw 3a with the locking hole 7. After the top plate 4 is placed on the bracket 3, the fixing screw is fixed from below. The bracket 3 and the top plate 4 are integrally fixed by screwing 3c into the top plate 4 through the insertion hole 3b. Thereby, the top plate 4 attached to the support | pillar 2 can be suitably utilized as a work plate.
[0023]
At this time, the top surface of the top plate 4 and the top surface of the wiring duct cover 6 are flush with each other by engaging the bracket 3 with the locking hole 7 having the same height as the locking hole 8 to which the wiring duct 5 is attached. It can be attached to become.
[0024]
In the wiring duct device in the work table configured as described above, the locking claws 10e are engaged with the front and rear locking holes 8 so that the pair of frame members 10 face each other from the front and rear of the support column 2. As a result, the wiring duct 5 which is integrated and has a substantially U-shaped cross-section with an open top is formed, so that the wiring duct 5 can be easily configured to the support column 2.
[0025]
Further, since the wiring duct 5 is attached between the two columns 2 by engaging the locking claws 10e of the respective frame members 10 with the desired locking holes 8 in the columns 2, the respective frame members 10 Can be easily engaged and disengaged or moved with respect to the support column 2 as necessary.
[0026]
Further, the column 2 in the present embodiment is formed in a substantially convex shape in cross section, and is attached to the front and rear of the column 2 via the bracket 3 in order to mount the wiring duct 5 through the locking hole 8 in the narrow part. It can be mounted at the same height as the top plate 4 provided.
[0027]
In addition, a wiring duct cover 6 is placed on the upper part of the wiring duct 5 so as to cover the upper opening, and the cords C housed inside the wiring duct 5 are concealed so that the appearance is improved. In addition, since the folded piece 6b of the wiring duct cover 6 supports the upper edges of both the frame members 10 from above, the wiring duct 5 is reinforced.
[0028]
Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.
[0029]
For example, in the above-described embodiment, the wiring duct 5 is formed so as to have a substantially U-shaped cross section that opens upward, but may be any shape that can accommodate at least the cords C inside the wiring duct. You may form in the cross-sectional substantially U shape which opens.
[0030]
Further, the wiring duct 5 is configured by opposing the same-shaped frame members 10 and 10 formed in a substantially L-shaped cross section, but both the frame members do not need to be formed in the same shape, and at least A wiring duct should just be comprised when arrange | positioning facing.
[0031]
Further, the support column 2 for attaching the wiring duct 5 is formed so as to have a substantially convex shape in cross section composed of a wide portion and a narrow portion. The cross-sectional shape can be variously modified as long as there are a plurality of stop holes formed in the vertical direction.
[0032]
