Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention is particularly applicable to cord wiring in a desk in which a cord is wired horizontally between desks placed side by side on the left and right, or between desks and top plates placed side by side. It is related to the device.

《Prior art and problems》 Conventionally, a device in which a cord is wired to another desk placed side by side in the left-right direction has wires attached to both the left and right ends of the rear edge material of the top plate, on the top, bottom, right and left, and on the rear side. A duct support with an opening is provided, and a U-shaped wiring duct is provided between both supports.The rear of the support is provided with a removable rear cover, and the outer surface is provided with the side edge material of the top plate. The upper part is closed with a removable side cover, and the upper surface of the support and the duct is closed with a removable duct cover with a wiring outlet in the upper part, and the wiring outlet has a removable blocking piece. If you want to wire the cord horizontally in a closed configuration (Japanese Utility Model Publication No. 63-110228), remove the top cover and side cover, wire the cord to the adjacent desk (top board), The top cover was attached.

In other words, if the top panels on both sides are installed at the same height, the outer surfaces of the wiring ducts will be located at the same position on the sides of each top panel, so the cords only need to be routed horizontally. However, if the heights of the adjacent top plates are different, the outer surface of the wiring duct on the lower side top plate will be blocked by the legs of the higher side top plate, so it is not possible to route the cord horizontally. There was a problem that I couldn't do it.

[Purpose and structure of the present invention] The present invention has a simple structure and allows wiring work to be easily performed even if the heights of the tops of desks installed side by side are different or the same. In addition, the purpose is to provide a cord wiring device for a desk that is aesthetically pleasing, and its structure consists of a cord wiring device that is continuous with the rear end of the top plate and the rear end of the legs, etc. In a cord wiring device for a desk in which the upper surface of the insertion part and the opening on the outer surface of the vertical cord insertion part are closed with removable horizontal and vertical covers, the cord wiring part is located above the vertical cover and the opening on the outer surface of the vertical cord insertion part is closed.

position.

Next, the insertion groove 44 of the corner cap 44
6,446 are fitted from above to the front insertion protrusion 102 of the rear end edge material 10 and the rear fitting protrusion 351 of the curtain plate corner cap 35 to attach the corner caps 44 to the left and right ends of the cord horizontal insertion part 4. Attach.

Next, the fitting recesses 511, 511 are connected to the lid support protrusion 53.
0,530, and has an open/close lid 51 rotatably provided on its upper end surface, the lid support member 5 can be attached to both the left and right ends, the center, or both ends, depending on the installation state of the OA equipment. The locking recess 10 is located at one end or at the center of the locking recess 10.
1,310 to lock the locking protrusion 50...
It is placed on the cord support member 41.

Next, between the opening and closing lids 51, 51, the horizontal cover 42,
42 is attached by locking the front and rear locking protrusions 421, 421 and the front and rear locking recesses 101, 310.

The present invention is constructed as described above, and when a power cord for OA equipment, etc. is introduced from the floor into the horizontal cord insertion section 4, the cord is first inserted through the vertical cover 8, the insertion hole cap 45, the corner cap 44, and the horizontal cover 4
2 and 42, open the opening/closing lids 51 and 51, and connect the wiring, and then attach the vertical cover 8 and the like again.

Also, if you want to introduce the cord from an adjacent desk at the same height, remove the horizontal covers 42, 42, corner caps 44, and insertion hole caps 45.
After inserting the cord into the horizontal cord insertion part 4,
Attach the corner cap 44 and side covers 42, 42.

On the other hand, if a desk top board that is set lower than the normal height of the desk top board is placed next to it to use OA equipment, etc., the vertical cord insertion part of the higher desk The lower end cap of the vertical cover is attached to the outer surface of the vertical cord insertion portion 23 by contacting the lower end of the removed vertical cover 8 with the cover seats 232, 232 formed at the lower end of the vertical cover 23.

As a result, an opening 230 is located between the upper end of the vertical cover 8 and the insertion hole cap 45 at the upper end of the vertical cord insertion part 23 and communicates with the horizontal cord insertion part 4.
is formed, and a cord is inserted through this opening 230 and below the other top plate.

In the embodiment, the cord horizontal insertion part 4 is composed of a cord support member 41, a lid support member 5, an opening/closing lid 51, a corner cap 44, an insertion hole cap 45, etc., but this does not depart from the gist of the present invention. It can be changed as appropriate within the range.

<<Effects>> As described above, the present invention allows the horizontal cord insertion part and the vertical cord insertion part to communicate with each other, and is located above the removable vertical cover that closes the opening on the outer surface of the vertical cord insertion part. While the insertion hole cap of the insertion part is detachable, there is also a lower end cap at the lower end that is approximately the same height as the insertion hole cap, so when the tops of desks, etc. placed side by side on the left and right are the same height. The cord can be routed horizontally by removing the insertion hole cap, and if the heights of the top boards of desks placed side by side are different, the lower end cap of the vertical cover on the higher desk can be used. If you remove the vertical cover and attach it to the vertical cord insertion part with it in its lowest position, there will be an insertion hole at the upper end of the vertical cord insertion part for wiring the cord horizontally between the insertion hole cap and the upper end of the vertical cover. It can be easily formed.

In other words, the present invention is very convenient because it is possible to easily wire the cords even to desks arranged side by side with different top heights by attaching and detaching the cap at the lower end of the vertical cover.
