DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk preferably used in a so-called dealing room.

[0002]

2. Description of the Related Art Conventionally, as a desk of this type, a desk main body having a use surface side top plate portion and an opposite side top plate portion lower than the use surface side top plate portion has been provided. It is known that a back frame, which plays a role of a blindfold or the like on the back surface, extends upward from the top plate surface and is continuously provided. In this case, the display device of the terminal device, the communication device and the like are placed on the back side top plate portion, and the keyboard and the like are placed on the use side side top plate portion.

[0003]

However, there is a demand for a device such as this, which is inefficient in space and allows other devices and the like to be mounted above the display device and the like. Therefore, it is possible to place a shelf on the back side top plate part so as to straddle the devices, or to horizontally fix the hood to the upper end of the back frame and place other devices on it. Something that has been considered is considered.

However, when the shelf is provided on the back side top plate so as to straddle the display device and the like, the legs of the shelf are located on the side of the devices. Therefore, when a plurality of desk bodies are used in a row in the left-right direction, it is difficult to drop continuous wiring on the back side of the equipment because the leg portions of the shelf board interfere. Since the wirings connected to the communication line cannot be easily removed from the equipments and reconnected, the poor handling of the continuous wirings is a fatal defect in this type of desk. On the other hand, when a shelf-shaped hood is fixed to the upper end of the back frame, such a defect is eliminated, but if such a hood is fixed, the installation work of the equipment and the equipment It is necessary to perform wiring connection work and the like to the back surface in a small space, and this easily causes a problem in workability in new installation or rearrangement.

An object of the present invention is to eliminate all such disadvantages.

[0006]

In order to achieve the above object, the present invention takes the following measures. That is, the desk according to the present invention includes a desk body,
With a back frame attached to the back of this desk body,
A desk including a hood detachably attached to the back frame, wherein the back frame is positioned at least below an upper frame member that forms a continuous opening portion on the left and right sides. A hood main body that includes an intermediate horizontal member and left and right continuous grooves that are provided by expanding the intermediate horizontal member upward, and a hood main body that extends from the upper end portion of the back frame onto the desk main body. The hood main body is fixed to the base end of the hood main body, and is inserted into the opening of the back frame.

In order to efficiently connect the desks of the present invention with their back surfaces in close contact with each other, the opening portion of the back frame has an opening width dimension approximately twice the width of the leg rod of the hood, and the intermediate cross member. Two left and right continuous grooves are provided in parallel with each other so that the desk body can be mounted on both surfaces of the back frame.

In order to conveniently arrange the display device, the input device, and the communication device, the desk body is provided with a use surface side top plate portion and a back surface side top plate provided lower than the use surface side top plate portion. It is preferable that the hood main body is located above the back side top plate portion. The desk of the invention of the present application may be one in which a plurality of desk bodies and a back frame are arranged in a row in the left-right direction, depending on the purpose.

[0009]

With such a structure, the hood body cantilevers above the back side top plate portion of the desk body, so that an obstacle corresponding to the leg portion of the shelf is formed. Will not exist on the back side top plate part. Therefore, it is possible to easily perform the operation of dropping or taking out the continuous wirings that are still connected to the devices or the like on the back side of the devices placed on the back side top plate portion. Moreover, the hood can be pulled out from the back frame by lifting the hood body upward, and the hood can be completely removed. Therefore, when installing the devices on the desk body or wiring the devices, it is possible to proceed with the work without the hood.

Further, according to such a structure, the hood can be mounted and used only at a necessary portion, and in this case, the position of the hood can be appropriately changed.
