Abstract

PROBLEM TO BE SOLVED: To provide a duct cover which improves look of a table when the cover installed with a holder is attached to a top board of the table, and which does not form unnecessary opening on the top board. SOLUTION: A sliding lid 58 to open and close a take-out opening for cords, etc., a cover to widely open and close a duct and a lid 44 which opened and closes a slit 40 are equipped on a table which can be used in three ways. When the lid 44 is rotated downward to open the slit 40, a thin hooking part 42A of a holder 42 may be inserted into the slit. As above, the holder 42 can be attached to the top board without opening a cover 26, therefore, the table looks good and things do not fall off from the duct. Also, the lid 44 does not become hindrance because the same is retreated by downward rotating the lid 44.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk duct cover which is attached to a duct formed on a tabletop for wiring a cord to a telephone or the like used on the tabletop.

[0002]

2. Description of the Related Art As shown in FIG.
A part of 4 is formed with a duct 16 for drawing out an information code and a power cord from the floor onto the top plate 14. A duct cover 72 whose opening is openable and closable by a lid 70 is fitted into the duct 16. When a power supply or the like is not used, the lid 70 is closed to improve the appearance of the desk 12, and a writing instrument or the like is inserted through the opening. Is designed not to fall on the floor.

Incidentally, a holder 42 such as a stand may be fixed to the desk 12, but there is a holder having a U-shaped holder 42 in which a hook portion 42 A is formed to be bent.
By inserting the hook portion 42 </ b> A into the duct 16, the holder 42 can be firmly fixed to the top plate 14.

However, although the thickness of the hook portion 42A of the holder 42 is only a few millimeters, it is necessary to fully open the lid 70, and not only the appearance is poor, but also objects fall from the opening and are lost. There is.

[0005]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention improves the appearance of a desk when a holder is mounted on a top plate, and also provides a desk duct that does not form an unnecessary opening on the top plate. It is an object to provide a cover.

[0006]

According to the first aspect of the present invention, a holding frame is mounted on a cord extracting duct formed on a tabletop of a desk. This holding frame,
The cover is pivotally supported so as to be openable and closable, and the cover covers the opening of the holding frame. Further, the cover has an elongated cut formed therein, and is covered with a rotatable lid pivotally supported by the cover.

The lid is pivoted downward to release the cut. Therefore, for example, when inserting the hook portion of the holder having a small thickness into the duct, the lid can be rotated downward and inserted into the duct through the cutout without opening the cover.

As described above, by rotating the lid downward, the lid is retracted from the top plate, so that it does not become an obstacle. In addition, since it is not necessary to open the cover to form an unnecessary opening, the appearance is good and the object does not fall from the duct.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 4, a desk duct cover 10 according to the present embodiment has a holding frame 1 fitted in a rectangular duct 16 formed on a top plate 14 of a desk 12. As shown in FIG.
8 is provided. A claw 20 is protruded from the outer peripheral surface of the holding frame 18, and an outer edge thereof is cut so as to be flexible.
The claw 20 elastically deforms and presses the inner wall of the duct 16,
The desk duct cover 10 is prevented from falling out of the duct 16.

A flange 22 projects outward from an upper opening edge of the holding frame 18 to shield the opening edge of the duct 16. Further, at the corners of the holding frame 18, shafts 24 are provided so as to protrude in directions facing each other. This shaft 24
A long groove 30 of a bearing 28 formed on the back surface of a long plate-like cover 26 that opens and closes the opening 18A of the holding frame 18 is engaged with the cover so as to rotate and slide.

A narrow portion 30A is formed at one end of the long groove 30, and unless the cover 26 is pulled out with force,
The bearing 28 does not come off the shaft 24.
A guide wall 32 extends downward from the shaft 24 on the inner wall of the holding frame 18. Between the guide wall 32 and a guide plate 34 extending in parallel with the guide wall 32, both ends in the width direction of the cover 26, which has been turned vertically, are sandwiched, and the long groove 30 has slipped out of the shaft 24. In this state, the cover 26 slides up and down.

Further, a support plate 3 is provided on the shaft side of the cover 26.
6, a projection 38 is provided on the free end side of the cover 26, and functions as a cradle when the cover 26 is closed.

On the other hand, both ends of the cover 26 are cut off at a width of about 5 mm to form a long notch 40. When the cover 26 is closed, a gap between the cover 26 and the opening 18A of the holding frame 18 is formed. Hook 4 of holder 42 of stand S shown in FIG.
2A constitutes an insertable slit.

The notch 40 can be opened and closed by an elongated lid 44. From both ends of the lid 44, shafts 46 projecting in the longitudinal direction are provided. The shaft 46 is supported by a bearing 48 formed on the back surface of the cover 26 and having a side cut open. And lid 4
4 is supported by a bearing 48 provided on the back surface of the cover 26, so that the end surface 44 </ b> A on the base end side of the lid 44 abuts on the raised surface of the cut 40, that is,
From the state where the cover 4 and the cover 26 are flush with each other, the cover 26 can be rotated only to bend downward.

For this reason, as shown in FIG.
The notch 40 is opened so as to enter the holding frame 18, and the notch 40 is closed with the lid 44 and the cover 26 flush. Further, a step 50 is formed at the longitudinal end of the cut 40, and when the step 52 formed on the lid 44 gets over the step 50,
In addition to providing a click feeling, the step portion 50 and the step portion 52 are engaged to function as a stopper, so that the lid 44 is not accidentally opened downward.

On the other hand, the free end of the cover 26 is
An outlet 54 is formed so that cords can be taken out when the cord 6 is closed. A guide portion 56 is formed at the edge of the outlet 54 along the longitudinal direction of the cover 26. Both ends in the width direction of a slide lid 58 that opens and closes the outlet 54 are slidably held by the guide portion 56.

An operation knob 60 is provided at an end of the slide lid 58, and a locking claw 62 whose outer periphery is cut in a U-shape is provided at the other end. I have. The locking claw 62 stops by engaging with a rack portion 64 formed at the center of the cover 26, or slides over the rack portion 64 while giving a click feeling while sliding.

Next, the desk duct cover 10 according to the present embodiment.
The operation of will be described. The desk duct cover 10 has a slide lid 58 that opens and closes an outlet 54 for taking out a cord and the like.
A cover that opens and closes the duct 16 and a lid 44 that opens and closes the cut 40 are provided, and three types of usage can be selected.

Here, the characteristic feature is that, as shown in FIG. 5, the lid 44 is pivoted downward to open the cut 40, and the hook portion 42A of the thin holder 42 is inserted. is there. Thus, even if the cover 26 is not opened,
Since the holder 42 can be attached to the top plate 14,
The appearance is good, and no objects fall from the duct 16.
Further, by rotating the lid 44 downward, the lid 44 retreats from above the top plate 14 and does not become an obstacle.

[0020]

According to the present invention, the desk has a good appearance when the holder is mounted on the top plate, and unnecessary openings are not formed on the top plate. do not do.
