Description

  The present invention relates to a wiring duct device in an article placement fixture such as a work table or a commodity display shelf.

  As a conventional wiring duct device of this type, for example, as described in Patent Document 1, an opening is provided over the entire length in the vertical direction on the inner side surfaces of the left and right columns of the workbench. There is one that allows the inside of the column to be used as a wiring duct.

JP 2001-29142 A (FIG. 1)

Like what is described in Patent Document 1 above, if an opening is provided on the inner side surface of the column over the entire length in the vertical direction so that the inside of the column can be used as a wiring duct, a general column is used. This is not possible, and the cost is high, and the strength of the support is reduced, so that a heavy article cannot be placed on the top plate.
In addition, since the line position is limited to both end portions, there is a problem that the degree of freedom of the wiring position is small.
Furthermore, because the opening on the inner side surface of the column is provided over the entire length in the vertical direction, the appearance is bad, and both side ends of the column are asymmetrical with respect to the width, so the work of the same shape When connecting the bases side by side, the columns of the connecting part cannot be shared.

  The present invention has been made in view of the above problems, and does not reduce the strength and appearance of the support column, and can be wired in the vertical direction at any position in the horizontal direction. It aims at providing the wiring duct apparatus in.

According to the present invention, the above-mentioned problems are solved as follows.
(1) In an article mounting fixture in which upper and lower portions of struts that are separated from each other are connected by an upper connecting member and a lower connecting member that face in the left-right direction, The engaging portions are provided so as to oppose each other in the vertical direction, and the upper and lower engaged portions are opposed to each other in the front duct forming member and the rear duct forming member for forming the front and rear portions of the wiring duct facing in the vertical direction. The front and rear duct forming members are attached so as to sandwich the upper connecting member and the lower connecting member from both the front and rear surfaces by engaging the engaging portions provided at the upper and lower portions of the surface, and the front and rear duct forming members are opposed to each other. The space formed between the planes is defined as a through space that faces in the vertical direction.

With such a configuration, it is possible to easily form a through space that faces in the vertical direction in the article mounting fixture without changing the shape of the column or performing any processing on the column. In addition, it is possible to share the support column of the connecting portion when the strength and appearance of the support column are not reduced and the article mounting fixture is connected to the left and right.
In addition, since the front and rear duct forming members can be attached at arbitrary positions in the left-right direction to form a through space between the opposing surfaces, the degree of freedom of the wiring position is increased.

(2) In the above item (1), the locked portion is a locking screw or a stepped pin having an enlarged diameter head projecting from the front surface of the upper connecting member and the rear surface of the lower connecting member. The stopping portion is a locking groove that opens downward and is fitted to the locking screw or the stepped pin from above and is prevented from coming off by the enlarged diameter head.

With such a configuration, the front and rear panels can be easily attached and detached, and by simply changing the mounting position of the locking screw or stepped pin in the left-right direction and locking the panel locking groove to them, The left and right positions of the space can be easily changed.
Further, when the locking screw is used, the front and rear panels can be fixed to the upper and lower connecting members by tightening the locking screw.

(3) In the above-mentioned item (1) or (2), the front and rear duct forming members are arranged in plan view facing each other by connecting side pieces to both side edges of the front duct forming member and the rear duct forming member. A slit-like gap is formed between the side pieces facing each other in the front duct-forming member and the rear duct-forming member so as to have a U-shaped cross section and facing the vertical direction through which the wiring can be inserted from the side.

  With such a configuration, cables and the like housed in the wiring space are difficult to see from both sides, so that the appearance is improved and the wiring is easily inserted into the wiring space of the wiring duct from the side. Or pull out to the side.

According to the present invention, it is possible to easily form a through space that faces in the vertical direction in the article mounting fixture without changing the shape of the normal support column or applying any processing to the support column. Therefore, the strength and appearance of the support column are not reduced, and the connection support column can be shared when connecting the article placement fixture to the left and right.
In addition, since the front and rear duct forming members can be attached at arbitrary positions in the left-right direction to form a through space between the opposing surfaces, the degree of freedom of the wiring position is increased.

It is a perspective view of the fixture for goods mounting provided with the wiring duct apparatus of this invention. Similarly, it is an enlarged front view of only the frame of the article mounting fixture. Similarly, it is an expansion exploded perspective view of a frame. Similarly, it is a partially cutaway enlarged front view of the connecting portion between the right column and the lower connecting member in the frame. It is the VV line expansion vertical side view in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an embodiment of a work table that is an example of an article mounting fixture including the wiring duct device of the present invention, FIG. 2 is a front view of the same frame, and FIG. 3 is an enlarged view of the frame. It is a disassembled perspective view.

  The work frame 1 is a pair of left and right columns made up of a square tube with its lower end fixed to the upper surface of the rear end of the base leg 2 facing in the front-rear direction (hereinafter, described with reference to the right front side of FIG. 1). 3, 3, a lower connecting member 4 connecting lower opposing surfaces of both supports 3, and an upper connecting member 5 connecting upper ends of both supporting posts 3.

A large number of engagement holes 6 in two rows on the left and right sides are arranged on the front surfaces of the left and right support columns 3 and 3 at regular intervals in the vertical direction.
Directly above the lower connecting member 4, on the front surfaces of both columns 3, a wiring duct 7 having a U-shaped cross section facing upward is seen from the side. Is attached so as to be detachable and changeable in height by engaging with a plurality of engaging holes 6 inside both the columns 3.

  Just above the wiring duct 7, a pair of brackets 8 (the right one is not shown) is provided on the front surfaces of both columns 3, and a plurality of engaging claws (not shown) protruding from their rear ends are provided. The racks 9 are detachably attached by engaging with the plurality of engagement holes 6 inside the support columns 3, and shelf boards 9 are fixed to the upper surfaces of the brackets 8.

  On the front side near the upper side of both columns 3, a shelf plate 10 smaller than the shelf plate 9 is provided with engaging claws (not shown) at the rear ends of the side plates 11, 11 fixed to both side surfaces thereof. By being engaged with a plurality of engagement holes 6 inside both struts 3, they are attached so as to be detachable and changeable in height.

  Engaging claws (not shown) at the rear ends of the side plates 13, 13 that are fixed to both side surfaces of the lighting device 12 and that face obliquely upward are attached to the front surfaces of the upper ends of the both columns 3. By engaging with the plurality of inner engagement holes 6, it is detachably attached.

  The lower connecting member 4 has a pair of upper and lower horizontal ridges 14 and 14 made of square tubes whose left and right dimensions are substantially equal to the dimension between the opposing surfaces of both supports 3 and whose front and rear dimensions are shorter than that of the supports 3. From a pair of left and right vertical rods 15 and 15 formed of square tubes whose upper and lower ends are fixed by welding so that the outer surfaces and the front and rear surfaces are aligned on the same surface on the opposite surfaces of both side ends. Therefore, both side ends of the upper and lower horizontal ridges 14 and 14 are opened.

As shown in FIGS. 3 and 4, the lower connecting member 4 joined in a frame shape is composed of a pair of left and right upper connecting brackets 16, 16 and lower connecting brackets 17, 17. It is connected to the lower facing surface of.
The left and right upper coupling brackets 16 and 16 can be inserted from both ends into the upper horizontal bar 14 by a bottom piece 16a facing in the left-right direction and a pair of upper and lower pieces 16b and 16b rising from the front and rear edges. The upper hooks 18 and 18 are connected to the outer ends of both upward pieces 16b.
As shown in FIG. 4, a nut 20 is fixed to the lower surface corresponding to the through hole 19 formed in the central portion of the bottom piece 16 a of each upper coupling metal 16 by welding.

  The left and right lower connecting brackets 17 are formed in a lower part of the lower horizontal bar 14 by a bottom piece 17a having a front and rear dimension slightly larger than that of the horizontal bar 14 and upward pieces 17b and 17b rising from the front and rear edges. It is formed in a U shape that can be more fitted in a side view and has hooks 21 and 21 that are hooked downward at the outer ends of both upward pieces 17b.

  Next, with reference to FIG. 4, the point which connects the lower connection material 4 to the right and left support | pillar 3 is demonstrated. In addition, since the connection structure of the lower connection member 4 to the right and left support | pillar 3 is left-right symmetric, only the right side is shown in figure.

  First, the left and right lower connection fittings 17 and 17 are fixed to both side end portions of the lower horizontal bar 14 in the lower connection member 4 as follows. That is, after the lower connecting bracket 17 is externally fitted to the side end portion of the lower horizontal flange 14 so that the hook 21 protrudes outward, the bolt is inserted from below into the through hole 22 provided in the bottom piece 17a. 23 is formed in the lower surface of the side end portion of the horizontal bar 14, and is screwed into the screw hole 24 to be tightened (see FIG. 4).

  Next, left and right upper coupling fittings 16 are inserted into the side ends of the upper horizontal bar 14 from the side, and the upper surface of the side edge of the upper horizontal bar 14 is inserted into the nut 20 on the lower surface of the upper coupling bar 16. The top end of the bolt 26 inserted from above is screwed into the through hole 25 provided in the upper part, and the upper connecting bracket 16 is temporarily fixed so as to be positioned in the middle part in the horizontal bar 14 (see the two-dot chain line in FIG. 4). .

  Next, before connecting the upper end portions of the left and right support columns 3 with the upper connecting member 5, the front and rear engagement holes 27, 27 in the form of longitudinal slits formed on the inner surfaces of the lower end portions of the support columns 3 (see FIG. 3). The hooks 21 and 21 of the left and right lower coupling fittings 17 in the lower coupling member 4 are dropped and engaged with the lower edge of the lower coupling member 4, and the lower ends of the lower coupling member 4 are temporarily supported by the left and right columns 3.

  Next, the slit-like front and rear engagement holes formed on the inner side surfaces of the middle portions in the vertical direction of the left and right support columns 3 are made smaller than those of the lower engagement holes 27 and 27. The left and right upper coupling fittings 16 that have been temporarily fixed are inserted into 28 and 28 (see FIG. 3). This insertion operation can be performed by slightly tilting the both columns 3 outward. The vertical dimension of the engagement hole 28 is such that the hook 18 of the upper connection fitting 16 can be inserted with a margin, and the height of the opening edge at the upper part of the engagement hole 28 is the hook of the lower connection fitting 17. In a state in which 21 is engaged with the engagement hole 27, it is aligned slightly below the upper surface of the upper horizontal bar 14, that is, as shown in FIG. Alternatively, it is positioned slightly below it.

Next, the bolts 26 are tightened, and the upper coupling fitting 16 is pulled up until the upper end thereof is in contact with or close to the lower surface in the horizontal cage 14. As a result, as shown in FIG. 4, the hook 18 is strongly engaged with the lower edge portion of the engagement hole 28, and the vertical force in the opposite direction acts on the support column 3 by the lower hook 21. Both ends of the lower connecting member 4 are firmly connected to the opposing surfaces of the left and right support columns 3 while preventing rattling in the vertical direction.
After the lower connecting member 4 is connected to the opposing surfaces of the left and right columns 3, the opposing surfaces at the upper end portions of both columns 3 are connected by the upper connecting member 5, whereby the assembly of the frame 1 is completed.

In this way, when the lower facing surfaces of the left and right support columns 3 and 3 are connected to each other by the lower connecting member 4 having a rectangular frame shape, the left and right support columns 3 made of rectangular tubes are connected to the left and right inner surfaces of the left and right support columns 3. The vertical rod 15 is brought into surface contact and the portion is reinforced, and the upper and lower horizontal rods 14 prevent wobbling in the left-right direction of the two columns 3, so that the strength and rigidity of the lower portion of the frame 1 are increased, and the entire frame 1 is increased. Is prevented from wobbling in the left-right direction.
Therefore, even if a large shelf plate 9 is attached to the front surfaces of both supports 3 just above the lower connecting member 4 and a heavy article is placed on this, there is a possibility that there will be any problem in the strength of the lower portion of the frame 1. The shelf board 9 is supported stably.

  The lower connecting member 4 is connected to the left and right support columns 3 by engaging the hooks 18 and 21 of the upper and lower connection fittings 16 and 17 with the engagement holes 28 and 27 on the inner surface of the support column 3, respectively. As a result, a relatively simple operation of simply pulling the upper coupling metal 16 upward is sufficient, and the work efficiency at the time of assembling the frame 1 is improved because it is not directly fixed to the support column 3 with a plurality of screws.

In addition, as shown in FIGS. 1-3, the wiring duct 29 which faces an up-down direction is provided in the right end part between the upper coupling member 5 in the upper coupling material 5 and the upper coupling material 4 at the right column. 3 is attached so as to be in contact with or in close proximity to the inner surface of 3.
The wiring duct 29 has a front duct forming member 30 whose vertical dimension is substantially equal to the dimension from the upper end of the support column 3 to the lower surface of the upper horizontal bar 14 in the lower connecting member 4, and a rear duct forming member 31 that is opposite to the front duct forming member 31. And.

  The front duct forming member 30 and the rear duct forming member 31 are respectively provided with side pieces 30a and 30a bent rearward and side pieces 31a and 31a bent forward on the both side edges thereof. By doing so, they are formed in a U-shape opposed to each other in plan view. Opposite side portions of the upper and lower ends of the side pieces 30a and 31a are notched along the vertical direction.

  As shown also in FIG. 5 which is an enlarged longitudinal sectional view, the front and rear end projecting dimensions of the front duct forming member 30 and the rear duct forming member 31 have the front and rear protruding dimensions, respectively. A mounting bracket 33 having a U-shape in plan view that is slightly smaller than the front and rear dimensions of the side pieces 30a, 31a in the portion 32 is fixed by welding or the like, and the lower half of the central portion in the left-right direction of the locking piece 33a perpendicular to them The portion is formed with a locking groove 34 that opens downward as a locking portion.

Since the lower connecting member 4 is formed on both the front and rear surfaces of the right end portion of the upper reed 14 and the front and rear surfaces of the right connecting portion of the upper connecting member 5, the screw hole 35 has a locking screw as a locked portion. 36 is loosely screwed.
When the locking groove 34 of the upper and lower locking pieces 33a in the front duct forming member 30 and the rear duct forming member 31 is dropped from above and locked to the shaft portion of each locking screw 36, the head of the locking screw 36 is obtained. By being prevented from coming off by the part, the both duct forming members 30, 31 are arranged on both the front and rear sides of the right end of the upper connecting member 5 and the upper reed 14 in the lower connecting member 4. They are detachably attached so that they are close to each other and face each other and sandwich the right end of the wiring duct 7 in the left-right direction provided below. In addition, the front and rear duct forming members 30 and 31 can be fixed by tightening the locking screw 36 after the attachment.

As a result, a through space 37 is formed between the facing surfaces of the front duct forming member 30 and the rear duct forming member 31 in the vertical direction, and the power cable of the illuminating device 12 is connected to the upper cut-off facing the front and rear. It can be inserted into the through space 37 from the notch 32, pulled out from the lower notch 32, and wired in the wiring duct 7 facing downward in the left-right direction.
In addition, a slit-like gap 38 is formed between the side pieces 30a and 31a facing each other so that a cable or the like can be easily inserted into the through space 37 from the side, It can be pulled out.

  As described above, in the wiring duct device according to the above-described embodiment, an article can be placed on a work table or the like without changing the shape of the column 3 that is generally used or performing any processing on the column 3. A through space 37 facing in the vertical direction can be easily formed in the fixture, and the front and rear duct forming members 30 and 31 are detachable, so that they can be easily removed when not in use.

  In addition, a plurality of left and right female screw holes 35 are provided in advance in the horizontal flange 14 and the upper connecting member 5 of the lower connecting member 4, and the locking screw 36 is screwed into the left and right female wires 35. The mounting position can be easily changed.

  In the wiring duct device of the above embodiment, the locking screw 36 is used to lock the front and rear duct forming members 30 and 31, but a stepped pin having an enlarged diameter head, etc. It may be fixed or screwed.
