Description

  The present invention relates to a table with a wiring function, and more particularly to a table with a wiring function that enables wiring of electrical equipment cords used on the top board under the top board.

  Conventionally, a plurality of top plates are connected in series and supported by a rod leg or a leg plate at the outer end of the top plate located at the end, and various tables with a structure supported by an intermediate leg at the connecting portion of the top plate are available. Is provided. Further, a basic structure is known in which a beam member is disposed on the peripheral edge of the lower surface of the top plate to reinforce the top plate, and a rod leg is fixed to a leg bracket connected to the beam member at a corner portion.

  A wiring duct device provided with a duct opening at the center of the top plate, a duct lid provided at the opening so as to be openable and closable, and communicated with a wiring duct under the top plate below the duct opening. Various tables are provided, and the form of the wiring duct device is also various.

  For example, in Patent Document 1, a predetermined gap is provided between front and rear top plates, and a wiring space is formed by attaching a hook-shaped member to the lower surface of the top plate along the gap. A notch is formed in the opposite part of the front and back top plates to form a substantially square duct opening in plan view, and the opening is opened and closed with a gap similar to the gap between the two wiring covers. A wiring duct device having a structure that is detachably provided is disclosed. Here, the back surface of the wiring cover has a backing plate portion, and the cover receiving portion provided in the duct opening portion in close contact with one side edge portion of the duct opening portion using the backing plate portion. It is supported so that it can be opened and closed. The support structure by the cover receiving portion is the same at the four edges of the duct opening having a substantially square shape in plan view, and can be attached along any edge. It can be installed with the long side of the wiring cover facing the long side of the top plate or the short side of the top plate, and the user is located on the long side or the short side of the top plate. It is characterized by being mounted in a direction that allows easy opening and closing operations.

  However, the wiring duct device described in Patent Document 1 has a space continuous with the gap between the top plates between the wiring covers in a state where the wiring covers are attached to the front and rear in parallel with the direction of the gap between the front and back top plates. It is formed and the cords can be pulled out using the space, there is no functional distinction between the gap between the top plates, and the lower wiring space can be used, but it is difficult to fix the position where the cords are drawn out . Also, if you remove both wiring covers and open the duct opening, access to the wiring space will be easier, but to install the wiring cover after wiring work, move the cords to a position where they will not get in the way. It takes time and effort.

  Further, in Patent Document 2, a gap is formed between the front and rear top plates, and a plate-like support portion projecting along the lower end of the wiring duct device is fitted into the gap, so that the front and rear top plates are fitted. The structure which provides a wiring duct apparatus in a boundary part is disclosed. Moreover, the point which supports a partition using the said wiring duct apparatus is also described. The wiring duct device described in Patent Document 2 can wire cords only by work on the top plate, but is not only bulky on the top plate and narrows the space used for the top plate, but also has a good appearance. Also inferior.

A table with a wiring function is provided, which is characterized by taking an open state that stands up.

  Further, in order to solve the above-mentioned problems, the present invention provides a table in which a duct lid is provided in an opening provided on the top plate so as to be openable and closable. The housing has a housing, and a pair of bearing tools are attached to the positions of both ends of the housing within the opening, the opening of the pair of bearing cylinders is arranged in parallel with the bearing device toward the inside of the opening, The duct lid body is a plate body having a half size that is slightly smaller than the inner shape of the duct frame. Cylindrical sleeves are provided at both ends of one side edge of the back surface of each duct lid body. Is configured to be rotatably fitted to a bearing cylinder of the bearing tool, thereby constituting a table with a wiring function (claim 2).

  Here, the lower end of the duct frame has a flange portion toward the inside of the opening, the flange portion is attached to the housing, and the fitting is held by sandwiching the housing from both sides to the bearing tool. And a fixing part that is placed on the upper surface of the flange part, and the fixing part is preferably screwed to the flange part.

  The duct lid has a holding portion that fits a spindle along one side edge of the lower surface, and the cylindrical sleeve is attached to an end of the spindle that protrudes at both ends from the holding portion. It is also preferable that the sleeve is fitted coaxially, and the sleeve is rotatably fitted inside the bearing tube of the bearing device.

  Further, when both the duct lids are raised to the open state, the duct lid body is rotated to a slightly overhanging state so that the base end portion of the duct lid body comes into contact with the bottom surface portion between the bearing cylinders of the bearing tool. More preferably, it stops and stabilizes in a substantially C-shaped state in which the free end sides of both duct lids approach each other (Claim 5).

  Alternatively, when both the duct lids are raised to the open state, they are rotated to an upright state of 90 degrees, and the claws provided in the vicinity of the base end portion of the duct lid and the rear engagement of the bearing cylinder It is also preferable to generate a click feeling at the part and hold it in parallel (Claim 6).

Since the columnar sleeves are fitted coaxially, and the sleeves are rotatably fitted inside the bearing cylinders of the bearings, both ducts can be used when both duct lids are in a horizontally closed state. The gap between the base ends of the lid can be narrowed to improve the appearance, and when both duct lids are in the raised state, the center of gravity is shifted in the opening direction from the center of rotation, so the opened state Is stable.

  According to claim 5, when the both duct lids are raised to the open state, the duct lid body is rotated to a slightly overhanging state so that the base end portion of the duct lid body is the bottom surface between the bearing cylinders of the bearing tool. Since it stops in contact with the part and becomes stable in a substantially C-shape with the free ends of both duct lids approaching, the duct opening can be opened widely, thereby facilitating wiring work for cords Furthermore, since the free end side can be prevented from contacting, it is possible to prevent the duct lid bodies from colliding with each other and being damaged.

  According to claim 6, when the both duct lids are erected in an open state, the claws and bearing cylinders provided in the vicinity of the base end portion of the duct lid are rotated to an upright state of 90 degrees. Since the click part generates a click feeling and is held in parallel, the duct opening part can be opened widely, thereby facilitating the wiring work of the cords and further preventing the free end side from contacting. Therefore, the duct lid bodies can be prevented from colliding with each other and being damaged.
