DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk suitably used in an office or the like.

[0002]

2. Description of the Related Art As a desk of this type, for example, a wiring duct space opened upward and on both left and right sides is formed at a position below a top plate near a rear end, and an upper surface of the wiring duct space is formed. It is closed by a plate-shaped duct cover so that it can be opened and closed, and a cutout hole is provided at the end of the desk on the side of the duct cover, which is always closed with a slidable lid,
It is known that a power supply line of an OA device or the like can be drawn out to a top plate by opening a lid thereof so that the power supply line can be drawn out from the cutout hole. Usually, in this type of desk, such a notch hole has a rectangular shape that is long in the left and right direction of the top plate so that a plurality of wirings can be pulled out on the top plate. The configuration is such that the number of wirings for drawing out the opening area can be adjusted.

[0003]

With such a structure, when one relatively thin wire such as a telephone line is led out, the opening area of the cutout hole must be reduced. Small office supplies such as clips fall from the opening below the desk. In such a case, when the wiring is completed, the lid is closed according to the wiring, but when using, for example, pulling the telephone close to the hand, the telephone line pushes the lid accordingly, and the lid is wired. It will be open from time. In other words, in the case of a slidable lid, when the desk is in use and the wires that are pulled out of the notch holes are hooked, the lid opens in accordance with that, the notch holes open wider than necessary and small office supplies fall. At the same time, the appearance was worsened.

An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the desk according to the present invention opens the wiring duct space.
A notch hole is provided in at least one longitudinal end portion of the duct cover disposed at a position to be closed in a closeable manner, and a lid that can be opened and closed in the longitudinal direction is provided in the notch hole. A moderation mechanism for causing the lid for opening and closing to perform a plurality of steps of moderation between the modes.
Structure is elastically deformable extending from the center of the base end of the lid
An engaging projection formed integrally with the tongue at the tip of the tongue;
Position corresponding to the engaging projection near the notch on the inner surface of the cover.
A plurality of engagement recesses that engage with the engagement protrusions provided on the
And characterized by the following.

In the desk according to the present invention, it is preferable that the duct cover, the lid, and the moderation mechanism are formed of synthetic resin.

[0007]

With such a structure, when the lid is opened, the lid is operated by the detent mechanism to be locked at a desired opening position of the cutout hole. Therefore, even if wirings drawn out from the notch holes come into contact with the lid and an external force is applied, the lid does not easily move from its opened position,
The required minimum opening area can be maintained.

Corner cover 8 fixed to side panel 2 and sleeve 3
Supported by The upper surface of the corner cover 8 is provided with a square hole for mounting an option such as a desktop panel, and a post cap 8a formed of a substantially rectangular flat plate is provided near the upper end of the square hole. It is engaged with the groove and closed.

[0010] The duct cover 6 is made of synthetic resin.
As shown in FIG. 2, a notch hole 62 is formed in a flat plate shape, and is always closed by a lid 61 slidably attached to one side end. The notch hole 62 has a rectangular shape, and its size is not particularly limited. For example, the size of the long side of the rectangle is about 50 m.
When the distance is about m, there is no practical problem in drawing out a plurality of power lines and connection cables when a plurality of OA devices are used. In the vicinity of both side edges of the notch hole 62,
A rail portion 63 that guides the lid 61 in the longitudinal direction of the duct cover 6 is provided on an inner surface of the duct cover 6 that faces the wiring duct space DS. This rail 63
Is a narrow portion 63 having the same length as the notch hole 62 and a narrow width.
a and a wide portion 63b wider than the narrow portion 63a
Consists of Therefore, the step 63c is formed in a portion corresponding to the vicinity of the rear part of the notch hole 62, and the lid 63 is prevented from falling off by the step 63c. The width of the wide portion 63b is such that a guide portion 61d of the lid 61 described later can easily slide without being elastically deformed, and the narrow portion 63a is a size that the guide portion 61d is slightly elastically deformed and slides. And it is sufficient. Also, from the inner surface of the duct cover 6 and near the end edge portion 62a of the notch hole 62,
An engagement concave portion 64 formed by connecting a plurality of triangular concave portions 64a is formed in the longitudinal center portion of the duct cover 6 between the rail portions 63. Further, at positions near both side edges of the inner surface of the duct cover 6, mounting claw bodies 65 having a convex portion on the outer surface at the distal end for mounting the duct cover 6 to the desk 1 are erected in a slightly inclined outward direction. In addition, a partition 66 for reinforcement is formed so as to cross the duct cover 6.

The lid 61 is made of a synthetic resin like the duct cover 6, and has a main body 61h in a rectangular shape corresponding to the shape of the notch hole 62, as shown in FIGS. It has a tongue piece 61b that extends rearward from the central portion of the base end portion 61a of the main body portion 61h and that can be elastically deformed in the vertical direction. On the upper surface side of the tip of the tongue piece 61b, an engagement projection 61c having a substantially triangular cross section is formed integrally with the tongue piece 61b. On the left and right sides of the tongue piece 61b, an annular guide 61d elastically deformable in the width direction of the lid 61 is provided so as to protrude from the base end 61a. The side projection 61e in the vicinity of the base end 61a of the guide portion 61d is connected to the main body portion 61 of the lid 61.
h, projecting slightly outward from the side surface, and
1 functions as a drop prevention claw. Further, a projection 61g is provided on the inner surface of the terminal end 61f of the side projection 61e so as to press the cover 61 when the cover 61 is removed from the cutout hole 62 to elastically deform the guide 61d. In the above configuration, the tongue piece 61b and the engagement recess 61c formed integrally with the lid 61, and the engagement recess 64 formed on the inner surface of the duct cover 6, constitute the moderation mechanism 67.

In such a configuration, the duct cover 6
And the lid 61 are formed separately, and the lid 61 is
It is mounted so as to open and close the notch hole 62 of FIG. As shown in FIG. 8, the left and right guides 61 d on the base end 61 a side of the lid 61 are attached to the rails 6 near the notch holes 62.
3 and push the lid 61 in the longitudinal direction of the duct cover 6 (indicated by an arrow X in the figure). Then, the engaging convex portion 61c at the tip of the tongue piece 61b of the lid 61 is engaged with the engaging concave portion 64 of the duct cover 6.
Engage with. When the lid 61 is further pushed in, the moderation mechanism 6
7 is elastically deformed in a direction perpendicular to the inner surface of the duct cover 6 so that the engaging projection 61c operates moderately to move the lid 61 moderately in the longitudinal direction of the duct cover 6. (FIG. 9). Here, when the lid 61 is pulled toward the side end of the duct cover 6, the notch 62 is formed by the lid 61.
Is closed. In this state, even if the lid 61 is further pulled toward the side end of the duct cover 6, the lid 6
1 does not move. This is because the side projection 61e of the guide portion 61d of the lid 61 is formed by the step portion 6 of the rail portion 63 of the duct cover 6.
The contact with 3a prevents the lid 61 from falling off the duct cover 6. The duct cover 6 to which the lid 61 is attached in this manner is attached to the desk D so as to close the upper surface of the wiring duct space DS.

When the desk D is used, for example, the telephone line T
When one C is pulled out from the cutout hole 62, as shown in FIG. 10, the opening of the cutout hole 62 has a sufficient space necessary for one telephone line to pass therethrough. It is closed by a lid 61. In this case, after the lid 61 is moved by the moderating operation by the moderating mechanism 67, the tongue piece 61b is moved.
Of the engaging concave portion 64 of the duct cover 6.
It is engaged with the two concave portions 64a, and the movement is suppressed. Therefore, even if the telephone line TC is pulled in contact with the lid 61, the lid 61 does not move in the longitudinal center direction of the duct cover 6, and the opening area of the cutout hole 62 does not increase carelessly.

In this embodiment, the notch 62
The lid 61 can be easily removed so as to make it easy to use as much as possible. That is, the guide portion 61 of the lid 61
“d” has an annular shape, and has a structure that can be elastically deformed in the width direction inside the lid 61, and a protrusion 61 g is provided upright at the end thereof. When removing the lid 61, the lid 61 is closed, and a force is applied from the outside so that the left and right protrusions 61g of the guide portion 61d are close to each other. By bringing the left and right protrusions 61g close to each other in this manner, the respective guide portions 61d
Is disengaged from the stepped portion 63c of the rail portion 63. Then, when the lid 61 is pulled outward in the longitudinal direction of the duct cover 6 from that state, each of the projections 6
1g exceeds the stepped portion 63c and the narrow portion 63a of the rail portion 63
Will come into contact with. In this state, each projection 61g is guided in the narrow width portion 63a, and slides while the guide portion 61d remains deformed in the inner width direction, and comes out of the rail portion 63. As described above, removing the lid 61 from the duct cover 6 does not require any tools or jigs, and does not require complicated work, and the finger 61c is used to pinch the projection 61g of the guide portion 61d. It can be easily removed with just a simple task.

The present invention is not limited to the embodiment described above, and the configuration of each section is not limited to the illustrated example, and various modifications can be made without departing from the spirit of the present invention. It is.

[0016]

According to the present invention, as described in detail above, when the lid is opened and closed, the lid operates moderately by the moderation mechanism, so that the notch hole can easily have a desired opening area. In addition, since the lid is locked at the desired opening position by the moderation mechanism, even if wirings drawn out from the notch holes come into contact with the lid and an external force is applied, the lid moves unnecessarily from the opened position. Therefore, the required minimum opening area can always be maintained. In particular, the moderation mechanism is a lid
Of elastically deformable tongue extending from the center of the base
And an engaging projection formed integrally with the tongue piece, inside the duct cover
Surface at a position corresponding to the engaging projection near the notch hole.
Composed of a plurality of engagement recesses to be engaged with the engagement projections
