  In the desk described in the above Patent Document 1, since it does not have a wiring function for accommodating and wiring the cords connected to the OA device, the cords are exposed and the appearance is deteriorated, There is a risk of cords being caught on the operator's feet.

  In order to prevent this, a wiring duct facing in the left-right direction is provided at an appropriate position of the leg (base body) below the top plate on which the display is placed, and cords are accommodated therein for wiring. It is possible.

  However, if the wiring duct is simply provided, when the main top plate on which the keyboard is placed is tilted forward and separated from the auxiliary top plate, the wiring duct and the cords wired to it are exposed from the upper front. , The appearance is worse.

  The present invention has been made in view of the above problems, and has a wiring function that makes it difficult to expose wiring ducts and cords such as OA equipment accommodated in the wiring duct from above and to improve the appearance. The purpose is to provide a desk.

According to the present invention, the above problem is solved as follows.
(1) The rear portions of the upper ends of the pair of left and right legs are connected to each other by a horizontal connecting rod, the main top plate and the auxiliary top plate are connected by both legs, and the auxiliary top plate is located behind the main top plate. A rear end of a wiring duct having an open top surface is attached to the front surface of the lateral connection rod, and the left and right legs are arranged in a plate shape above the wiring duct. The cover member is provided so as to cover the upper part of the front portion of the wiring duct.

(2) In the above item (1), both legs have top plate support members facing in the front-rear direction at the upper ends of the pillars, and the left and right top plate support members support both side ends of the cover member.

(3) In the above item (2), slit-shaped grooves that face in the front-rear direction and open inward are provided on the inner surfaces of the two top plate support members facing each other. Fit both ends to support.

(4) In the above item (2) or (3), the front end portions of the left and right top plate support members are connected by a second horizontal connecting rod, and the second horizontal connecting rod and the upper surface of the cover member are connected. Make it continuous.

(5) In the above item (4), the upper end of the rear surface of the second horizontal connecting rod is provided with a concave groove that faces in the left-right direction and opens rearward, and the front edge of the cover member is fitted into the concave groove. Thus, the upper surface of the second lateral coupling rod and the upper surface of the cover member are made continuous.

(6) In any one of the above items (1) to (5), the front and rear dimensions of the auxiliary top plate are made large enough to cover the rear end of the wiring duct.

(7) In any one of the above items (1) to (6), the rear end of the main top plate and the front end of the auxiliary top plate are arcuate shapes that complement each other in plan view.

  According to the first aspect of the present invention, even if the desk has an auxiliary top plate behind the main top plate by providing the left and right legs with cover members that cover the upper front of the wiring duct, Through the gaps between the top plates, the wiring duct and the cords accommodated in the duct are not easily exposed, and the appearance is improved.

In addition, since the articles that have slipped down from the top plates easily fall onto the cover member, the possibility of falling into the floor surface or the wiring duct is reduced.
Further, the cords can be supported by the upper surface of the cover member and arranged in an order in the wiring duct, or the extra length cord can be placed on the cover member.

  The auxiliary top plate is supported behind the main top plate, and the wiring duct is attached to the front surface of the horizontal connecting rod that connects the rear parts of the legs. Even if you go away and take a comfortable posture with your legs stretched deeply between the legs, your feet won't get caught in the wiring ducts or cords that hang down.

  According to the second aspect of the present invention, since the cover member having a large front-rear dimension can be supported by the left and right top plate support members, the wiring duct and the cords accommodated therein are less likely to be exposed.

  According to the invention described in claim 3, the cover member can be easily attached between the left and right legs without using fixing means such as a bracket or a screw.

  According to the fourth aspect of the present invention, since the second lateral coupling rod also functions as a cover member, the blinding effect of the wiring duct is increased even if the gap between the top plates is large.

  According to the fifth aspect of the present invention, the cover member and the upper surface of the second lateral coupling rod can be continued without gaps, so that the appearance is improved.

  According to the invention described in claim 6, since the opening to the wiring duct formed between the lateral connection rod and the cover member is covered with the auxiliary top plate, the cords accommodated in the wiring duct are seen from the rear upper part. It becomes difficult to be exposed.

According to the seventh aspect of the present invention, the main top plate and the auxiliary top plate are provided so as to be adjustable in height, and when the heights thereof are adjusted, the opposing ends are prevented from interfering with each other.
Moreover, since the opposing end of the main top plate and the auxiliary top plate bulges in an arc shape in either the front or back direction, a part of the cover member is difficult to see from above.

  The main top plate (3) has both side edges curved in an arc shape so that the left and right dimensions gradually become smaller toward the front, the front edge is concave, and the rear edge is convex. Each is curved.

  Contrary to the main top plate (3), the auxiliary top plate (4) is curved in an arc shape on both sides so that the left and right dimensions gradually become smaller toward the rear, and the front end edge is the main top plate. In order to complement the rear end edge of the plate (3), the plate (3) is curved concavely toward the rear, and a required gap is formed between the opposing surfaces. The front and rear dimensions of the auxiliary top plate (4) are such that the upper part of the rear opening surface of the wiring duct (17) described later can be covered with a margin.

  As shown in FIG. 4 in an enlarged manner, the rear lateral connecting rod (8) is made of an extruded product such as an aluminum alloy, for example, and the opening width is narrower than the rear portion on the vertical rear surface. Further, two upper and lower engaging grooves (12), (12) having a U-shaped cross section in side view are formed over the entire length in the left-right direction.

  An engagement groove (13) having a forward U-shaped cross-section in a side view is formed in the center of the front side of the rear lateral connecting rod (8) in the vertical direction. An upward locking piece (14) is projected.

The front surface below the engaging groove (13) is an inclined receiving surface (15) of the wiring duct (17), which is inclined forward so as to be continuous with the front surface of the upward locking piece (14). ing.
The front surface above the engagement groove (13) is a rearward inclined surface (16) that is substantially symmetrical with the inclined receiving surface (15) with the engagement groove (13) interposed therebetween.

  (17) is a saddle-shaped wiring duct having a substantially upward U-shaped cross section that is attached to the front surface of the rear lateral coupling rod (8) between the left and right legs (2) and (2). An upward base piece (17a) inclined forward and substantially equal to the inclined receiving surface (15) of (8), an inclined reception piece (17b) extending diagonally forward and downward from the lower end thereof, and extending horizontally forward and forward from the front end thereof A horizontal receiving piece (17c) and an upstanding piece (17d) standing upright from the front end of the horizontal receiving piece (17c), and the upper surface and the left and right side surfaces are open.

  On the upper surfaces of the inclined receiving piece (17b) and the horizontal receiving piece (17c), a large number of recesses (18) are formed in the lateral direction for preventing slipping.

  The upper edge of the upward base piece (17a) has a downward hook-like shape that can be engaged with the upward locking piece (14) from above in the engagement groove (13) on the front surface of the rear lateral connecting rod (8). The engagement hook (19) is provided continuously over the entire length in the left-right direction.

  In addition, on the slightly upper end of the upper base piece (17a), on the upper end surface of the engagement hook (19), a presser piece (20) standing up almost vertically and elastically deformable in the front-rear direction is continuously provided. On the rear surface of the upper end of the presser piece (20), an arcuate cross-section ridge (21) that can be engaged with the lower end of the upper opening edge of the engagement groove (13) protrudes over the entire length in the left-right direction. It is installed.

  To attach the wiring duct (17) to the front surface of the rear lateral connection rod (8), the upper base piece (17a) is positioned slightly above the engagement groove (13), and the engagement hook (19) is The engaging groove (13) is engaged with the upward locking piece (14) on the lower edge of the engaging groove (13) from above.

  At this time, the rear surface of the upper end of the presser piece (20) is slightly elastically deformed forward by contacting the front surface slightly above the engagement groove (13), and in this state, the protrusion (21) Engages with the lower end of the opening edge at the top of the engagement groove (13).

  As a result, as shown in FIG. 4, the rear surface of the upward base piece (17a) is in close contact with the inclined receiving surface (15) of the rear lateral connecting rod (8), and the ridge (21) is also engaged with the engagement groove (13 ), The wiring duct (17) can be stably mounted without rattling in the front-rear direction or moving upward.

  After installation of the wiring duct (17), as shown in FIGS. 2 and 3, both side surfaces of the latter half are opened to both sides behind the upper end of the left and right pedestals (2b). The cords (C) such as the OA equipment housed in the wiring duct (17) can be wired toward either the left or right side and led out from the open side.

  As shown in FIG. 1, the cords (C) derived from the side are inserted into a flexible cable card (23) formed by superposing a plurality of short storage tubes (22) in the vertical direction. In addition, it can be wired well on the floor surface.

  As shown in FIG. 3, the inner surface of the center part of the front and rear direction of the upper end of the left and right top plate support members (6) (only one is shown for left and right symmetry) faces the front and rear direction, and the front end is obliquely forward. Slit-like fitting grooves (24) that are inclined downward and have a front end extending horizontally toward the vicinity of the corner of the rear upper end of the front horizontal connecting rod (7) are formed to face each other. ing.

  By fitting the left and right ends of the flat cover member (25) formed by bending the punching plate into the left and right fitting grooves (24) so as to complement it, The cover member (25) is sandwiched and attached by the left and right top plate support members (6) so as to cover substantially the upper half of the wiring duct (17).

  The front edge of the cover member (25) is inserted into a left and right concave groove (26) formed at the upper end of the rear surface of the front horizontal connection rod (7), and the front surface of the cover member (25) and the front horizontal connection By making the upper surface of the flange (7) substantially continuous with the same surface, it is possible to prevent a gap from being formed between the rear end of the front lateral connection flange (7) and the front end of the cover member (25). The front horizontal connecting rod (7) also functions as a part of the cover member.

  As described above, in the desk (1) of the above-described embodiment, the front lower surface of the rear lateral connecting rod (8), which is the mounting surface of the wiring duct (17), is inclined forward with the inclined receiving surface (15). At the same time, the upward base piece (17a) of the wiring duct (17) is also tilted forward at substantially the same angle as the inclined receiving surface (15), and the wiring duct is connected to the upward locking piece (14) of the rear lateral connection rod (8). When the engagement hook (19) of (17) is engaged, the upward base piece (17a) comes into contact with the inclined receiving surface (15) in a forward inclined state.

  As a result, when the office worker operates the OA equipment on the desk with a comfortable posture with his legs greatly extended into the leg body, the knee or the like comes into contact with the lower surface of the wiring duct (17), and the upward force is applied to this. Even if it is added, the wiring duct (17) is difficult to come off.

  That is, for example, when the mounting surface of the wiring duct (17) in the rear lateral connecting rod (8) and the upward base piece (17a) of the wiring duct (17) are vertical, the upward force applied to the wiring duct (17) is Since it acts only on this, the engagement hook (19) is more easily disengaged from the locking piece (14). However, when the front hook is tilted as described above, the upward force is converted into a component force by the rear lateral connecting rod (8). Since this also acts on the inclined receiving surface (15), the wiring duct (17) is difficult to come off.

  Also, if the inclined receiving surface (15) is tilted forward, the vertical load of the wiring duct (17) attached in a cantilever state greatly acts on the inclined receiving surface (15) as a component force. The load resistance of (17) is increased, and the vertical load directly applied to the engagement hook (19) is also reduced.

  Furthermore, the upper end of the upper opening edge of the engaging groove (13) of the rear lateral connecting rod (8) is in contact with the upper end of the holding piece (20) of the wiring duct (17), and the holding piece (20) Since the protrusion (21) on the rear surface is in pressure contact with the lower end of the opening edge of the engagement groove (13), the wiring duct (17) is stably attached without moving in the front-rear and up-down directions.

Since the upward locking piece (14) of the rear lateral connecting rod (8) is inclined forward, the engagement hook (19) of the wiring duct (17) can be easily engaged therewith.
In addition, since the upper front portion of the rear horizontal connecting rod (8) is inclined rearward, the distance between the rear end of the cover member (25) and the upper end of the rear horizontal connecting rod (8) becomes large. The cords (C) can be easily dropped into the wiring duct (17).

  Between the upper ends of the left and right legs (2), that is, between the upper ends of the left and right top plate support members (6) and (6), a flat cover member (25) is located above the front half of the wiring duct (17). Since the wiring duct (17) and the cords (C) accommodated in the wiring duct (C) are disposed between the main top plate (3) and the auxiliary top plate (4) It is not exposed from above, and the appearance is improved.

  In addition, when the auxiliary top plate (4) having a small front-rear dimension is attached, the article slipped down from the top falls on the cover member (25), so that it is difficult to fall on the floor or the wiring duct (17). .

  Further, when wiring cords such as OA equipment placed on the auxiliary top plate (4) to the wiring duct (17) through the gap with the main top plate (3), the cover member (25) It can be supported by the upper surface, and can be wired in the wiring duct (17) from the rear end thereof, or the extra length cord can be placed on the upper surface of the cover member (25).

It is a perspective view of the desk with a wiring function of this invention. It is a side view similarly. Similarly, it is a central longitudinal cross-sectional enlarged side view of the main part. It is an expansion vertical side view of the wiring duct attachment part to a rear part horizontal connection rod.
