Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a desk preferably used in an office or the like.

[Prior Art] With the progress of so-called OA, many desks used in offices are provided with a function of storing and guiding a power line or a communication line in an attractive manner.

Conventionally, as a desk of this type, a wiring duct is formed between the front panel and the inner panel, and the top and bottom surfaces of the top plate communicate with each other in the vicinity of the edge of the top plate opposite to the use surface side. It is known that an elongated through window is formed so that the wiring introduced into the wiring duct from the floor or the like can be appropriately guided onto the top plate.

However, with such a configuration, it is difficult to insert a continuous wiring over a plurality of adjacent desks into the wiring duct of each desk without removing it from the device.

Therefore, both ends of the through window are extended to both left and right edges of the top plate and released to the side, and side windows continuous with the through window are also formed on the side plate so that continuous wiring can be thrown. Is also being developed.

Further, there is also a case in which an opening is provided near the edge of the top plate on the side opposite to the use surface so that the top surface and the bottom surface of the top plate communicate with each other, and a pipe-shaped optional fitting is arranged in the opening. .

However, according to this, a desktop panel, a tuft light, a manuscript stand, a telephone stand, etc. can be selectively attached to the optional mounting brackets as needed. A lid is attached to the part to prevent the opening from being conspicuous.

[Problems to be Solved by the Invention] However, in the conventional desks capable of throwing wiring, the upper end portions of the through window provided on the top plate and the side window provided on the side plate can be visually recognized from the user side. , Lids are provided on the through windows and the side windows.

Therefore, the number of parts is increased and the structure is complicated.
Moreover, if the wiring is bulky, it is necessary to remove the above-mentioned lid, but such small parts are easily lost. Therefore, when the wiring is removed and the lid is to be attached again, the whereabouts of the lid become unknown, which often causes confusion.

Further, in the desk in which the various options as described above are attached to the top plate, the structure of the lid mounting portion becomes complicated, and it is necessary to perform fine work. Therefore, a desk having such a wooden top plate is not suitable for such a structure. Moreover, when using the option, it is necessary to remove the lid, but since the lid is particularly small, it is easily lost. Therefore, similarly to the above, when the option is removed and the lid is to be attached again, it is easy to cause a problem that the whereabouts are unknown.

The present invention can eliminate the above-mentioned problems, and even when an option is attached, continuous wiring can be easily thrown in, and the wiring erected from the floor is guided into the wiring duct, It is an object of the present invention to provide a desk that can smoothly perform work for guiding wiring in a wiring duct onto the floor.

[Problems to be Solved by the Invention] The present invention takes the following means in order to achieve such an object.

That is, the desk according to the present invention is a desk including left and right side plates, a top plate, a front panel, and an optional mounting bracket, and the left and right side plates are on the upper surface of the non-use surface side. The top plate has a recessed portion at the end, and the top plate is disposed on the both side plates with the edge on the non-use surface side overhanging on the recessed portion, and the front panel is placed between the both side plates. The optional mounting bracket is constructed so that the lower end side of the mounting leg is fixed to the inner surface side of the front panel, and the mounting bracket main body is provided at the upper end of the mounting leg. And a gap for wire insertion that is continuous with the both recessed portions is formed between the top plate and the upper end side of the mounting leg through the wire insertion gap. Extend it to the upper side, and its upper end side and top plate anti-use surface Forming a gap of a predetermined width between the edges and the upper surface of the top plate. Then, a fixed inner panel is fixedly provided on the inner surface side of the front panel, and a wiring duct communicating with the wiring insertion gap is formed between the front panel and the fixed inner panel. The width of the front panel is narrower than that of the front panel, an opening is formed between the side edge and the side plate, and the movable inner panel is detachably attached to the opening.

The desk of the present invention does not directly support the top plate by the front panel, but even under such a structure, when it is desired to effectively prevent the central portion of the top plate from being bent downward due to a load. It is desirable that at least the central portion of the top plate is abutted and supported from the lower surface side by the fixed inner panel.

In order to perform the wiring work particularly smoothly, it is preferable to form openings on both sides of the fixed inner panel and cover the movable inner panels with the openings.

In order to make the gap hard to see from the use surface or the upper surface side and to secure the opening area of the gap as large as possible in the wiring throwing direction, the thickness of the top plate on the bottom surface of the edge of the top plate opposite to the use surface side Forming a sloped chamfer over the center of the top plate and near the top surface of the top panel, or on the inner surface of the upper edge of the front panel over the center of the front panel in the thickness direction and near the outer surface of the front panel It is preferable to form a chamfered portion.

The present invention can be applied to a so-called steel desk, of course, but since the lid or the like is not required at all and fine work is not required, the side plate, the top plate, the front panel and the inner panel are each made of wood. It can be applied without any difficulty.

The following can be mentioned as preferred embodiments when using a wooden side plate, a top plate, a front panel, a fixed inner panel and a movable inner panel.

First, when connecting the top plate and side plate with metal fittings,
While bolting the outer edge side half of the connecting fitting to the upper end surface of the side plate from the top side, place the top plate on this connecting fitting and place the inner edge half of the connecting fitting on the top plate from the bottom side. Bolting is preferable because the connection portion can be made inconspicuous.

When the side plate and the front panel are connected via a fixing metal fitting, the fixing metal fitting includes a side wall bolted to the inner surface of the side plate, a front wall bolted to the inner surface of the front panel, and a front wall thereof. From the viewpoint of strength, it is preferable to have a wall and a bottom wall that rigidly connects the lower edges of the side walls.

In order to securely fix the fixed inner panel to the front panel with a small number of members, the fixed inner panel is provided through the horizontal member that also serves as the bottom wall of the wiring duct and the standing member that is arranged below the horizontal member. The panel is preferably fixed to the front panel.

In order to increase the strength of supporting the top plate of the fixed inner panel, it is desirable that both ends of the horizontal member are brought into contact with the inner surfaces of the left and right side plates and the bottom wall of the fixing fitting is bolted to the horizontal member.

Even if both ends of the horizontal member are fixed by abutting against the side plates, in order not to reduce the degree of freedom of wiring, the horizontal member is partially formed with a notch for guiding the wiring on the wiring duct downward. It's good to do.

If you want to securely fix the option mounting bracket to the desk and especially to increase the support strength of the option, fix the lower end of the mounting leg of the option mounting bracket to the inner surface of the front panel and the horizontal member. You should keep it.

In order to smoothly attach the option mounting bracket to the inner surface of the front panel, it is preferable to bolt the option mounting bracket to a position corresponding to the opening.

[Operation] With the desk having such a configuration, the recessed portion of the side plate and the wiring insertion gap continuous to the recessed portion are continuous with each other across a plurality of adjacent desks. for that reason,
It is possible to throw a wire continuous over a plurality of desks into the recessed portion of each desk and a wiring insertion gap without removing it from the device. In addition, the recessed portion and the wiring insertion gap cannot be easily seen from the user side. Therefore, it is not necessary to provide separate lids for closing the recessed portions and the wiring insertion gaps.

Also, the gap provided between the upper end of the mounting leg of the optional mounting bracket, the edge of the top plate on the side opposite to the use surface, and the top face of the top plate is continuous with the above-mentioned gap for wiring insertion, and Continuity is not compromised by the optional mounting hardware. Therefore, the wiring can be dropped from the upper surface side of the top plate into the wiring insertion gap and the continuous wiring can be thrown even with the option mounting bracket attached. In addition, this optional mounting bracket is one in which the lower end side of the mounting leg is fixed to the inner surface side of the front panel, and the upper end side is extended to the top plate through the wiring insertion gap. The plate does not need to be provided with any opening for mounting the optional mounting bracket. Moreover, in the present invention, the fixed inner panel is fixedly provided on the inner surface side of the front panel to form the wiring duct communicating with the wiring insertion gap, so that the wiring erected from the floor is inconspicuous. It can be guided and merged with the continuous wiring, or can be connected to the equipment arranged on the top plate or the optional equipment through the gap. Since an opening is formed between the side edge of the fixed inner panel and the side plate, and the movable inner panel is detachably attached to the opening, a hand or the like is inserted into the narrow space to secure the wiring. Since it is not necessary to guide, various wiring work can be performed smoothly.
