Description

The present invention relates to a table suitable for use in offices and the like.

As a table of this kind, one is known that is equipped with a top plate having an opening for wiring insertion at the unused end, and a cord duct arranged on the lower surface side of the top plate in correspondence with the opening. (For example, see Patent Document 1).

Incidentally, in a conventional table of this kind, a cord duct having a substantially horizontal bottom plate is disposed below the opening. Therefore, when there is a desire to store a wagon or the like under the top plate, the height of the bottom plate is raised and the cord duct is made shallower to meet the request. However, if the cord duct is made shallow, there is a possibility that it will not be possible to accommodate the power outlet etc. inside the cord duct, and there is also the possibility that the power outlet will protrude from the opening to the top of the top plate (problem). 1).

On the other hand, if there is a desire to increase the capacity of the duct, it is normal to respond by lowering the height of the bottom plate and deepening the cord duct. It becomes difficult to access the installed power outlet, etc., and it becomes difficult to insert and remove the power cord from the opening to the power outlet (Problem 2).

The code c2 is a signal code for connecting the operation switch 33 and the control box 34.

As described above, and as shown in FIGS. 4 to 8, the cord duct 5 is arranged on the lower surface 2c side of the top plate 2 in correspondence with the opening 2x of the top plate 2. In the case of this embodiment, the cord duct 5 is used to power cords other than the power supply cord c1 and the communication cord c2 described above, that is, mainly to devices such as lighting fixtures and information processing devices arranged on the top plate 2. It is used to guide codes for transmitting information and communication signals. The left-right width w1 of the cord duct 5 is set to be smaller than the left-right width w2 of the top plate 2 and larger than the left-right width w3 of the opening 2x of the top plate. Further, this cord duct 5 has a front side area 51 and a back side area 52, and the back side area 5B faces the opening 2x of the top plate 2.

As shown in FIGS. 4 to 8, the front side area 51 includes a front side bottom plate 53 forming a bottom surface 51a, a front plate 54 standing up from the front end of the front side bottom plate 53, and a rear side from the upper end of the front side bottom plate 54. It is provided with a front side attachment part 55 which extends to the top plate 2 and is attached to the top plate 2. As shown in FIG. 8, the area from the used end 2a of the top plate 2 of this table to the rear end of the front side area 5A of the cord duct 5, that is, the rear end of the front side bottom plate 53, is the wagon storage area AW. The front side area 51 is set to a depth that does not interfere with the wagon W inserted into the wagon storage area AW. As shown in FIGS. 4, 5, and 8, the front bottom plate 53 is provided with a window 5w for attaching a monitor arm fixing clamp. Further, as shown in FIGS. 4 to 8, flanges 53a are provided upright from both left and right edges of the front bottom plate 53. As shown in FIGS.

As shown in FIGS. 4 to 8, the back area 52 includes a back bottom plate 56 forming a bottom surface 52a, and an intermediate plate 57 connecting the front end of the back bottom plate 56 and the rear end of the front bottom plate 53. , a back plate 58 that stands up from the rear end of the back bottom plate 56, and a back mounting portion 59 that is continuous with the upper end of this back plate 58, forms an angle, and engages with the non-use end 2b side of the top plate 2. We are prepared. The bottom surface 52a of the back region 52 is deeper than the bottom surface 51a of the front region 51, and these bottom surfaces 51a and 52a are continuous in a stepped manner via the back surface 57a of the intermediate plate 57. Further, as shown in FIG. 8, the bottom surface 52a of the back area 52 is inclined so that the front side 52a1 is lower than the back side 52a2. More specifically, as shown in the figure, the bottom surface 52a of the back area 52 has a virtual normal h set at the center of the bottom surface 52a in the front-rear direction that interferes with the front edge 2x1 of the opening 2x of the top plate 2. It is tilted at an angle that is close to that of the other. This back area 52 is capable of accommodating a power outlet P and the like, as shown in the figure.

A cover 6 that partially covers the opening 2x of the top plate 2 can be removably attached above the cord duct 5.

As shown in FIGS. 3 and 6 to 9, the cover 6 includes a cover main body 61 having a shape substantially corresponding to the opening 2x of the top plate 2, and an angled An engaging portion 62 that has a shape and can be engaged with the rear attachment portion 59 of the cord duct 5, and a tip portion 63a of the engaging portion 62 that extends diagonally forward from both left and right ends of the engaging portion 62 is connected to the front side area of the cord duct 5. A positioning arm 63 that positions the cover 6 by abutting against the cover 51 is provided. With this cover 6 attached, a gap S2 for leading out the cord is formed between the front edge 61a and both side edges 61b of the cover main body 61 and the front edge 2x1 and both side edges 2x2 of the opening 2x of the top plate 2. It has become so. As shown in FIG. 8, the power cord c3 and the like connected to the power outlet P can be pulled out onto the top plate through this gap S2.

As described above, according to the configuration of this embodiment, the cord duct 5 forms a step-shaped bottom surface 51a of the shallow front region 51 and a bottom surface 52a of the back region 52 deeper than the front region 51. Since the cord ducts 5 are continuous so as to form a shape, it is easy to design a wagon W etc. to be stored under the top plate 2 without impairing the original performance of the cord duct 5. That is, by setting the wagon storage area AW below the shallow front area 51, the depth of the deep back area 52 can be set without being influenced by the height of the wagon W. Therefore, it is possible to store the wagon W etc. under the top plate 2 without causing problems such as the storage capacity of the cord duct 5 being unduly reduced or the stored power outlet P etc. popping out from the opening 2x of the top plate 2. becomes easier. Specifically, since the deep back region 52 faces the opening 2x, by arranging the power outlet etc. in the back region 52, the power outlet P etc. arranged in the cord duct 5 can be It is possible to prevent the occurrence of a problem in which the top plate 2 protrudes from the opening 2x of the top plate 2 to the upper surface side of the top plate 2.

In addition, since the bottom surface 52a of the back area 52 is sloped so that the front side is lower than the back side, even if the back area 52 is relatively deep, the power outlet P stored in the back area 52 can be The cord can be easily connected to and removed from a communication outlet, etc., and can be easily routed. In particular, in this embodiment, the bottom surface 52a of the back region 52 is inclined at an angle such that the virtual normal h, which is set at the center of the bottom surface 52a in the front-rear direction, approaches the front edge 2x1 of the opening 2x without interfering with it. Therefore, the cord can be smoothly pulled out onto the top plate from the power outlet or communication outlet stored in the back area 52.

Since the opening 2x of the top plate 2 has a shape obtained by cutting out the non-use end 2b of the top plate 2, the opening 2x is positioned closer to the non-use end 2b of the top plate 2, and the surface of the top plate is In addition to being able to increase the effective area, the processing for forming the opening 2x is easier compared to forming a window-shaped opening, and the window-shaped opening is formed near the unused end 2b. Unlike the case where the opening 2x is formed, such an opening 2x can be formed without causing a decrease in strength near the opening edge.

Since the left and right width dimension w1 of the cord duct 5 is set to a value smaller than the left and right width dimension w2 of the top plate 2 and larger than the left and right width dimension w3 of the opening 2x, the width dimension w2 is different from each other. When a plurality of plates 2 are prepared, the code duct 5 corresponding to the top plate 2 with the smallest width dimension w2 is shared with other tables having other top plates 2, thereby making it possible to standardize the design.

In this embodiment, the area from the used end 2a of the top plate 2 to the far end of the front side area 51 of the cord duct 5 is defined as the wagon storage area AW, and the front side area 51 of the cord duct 5 is inserted into the wagon storage area AW. Since the depth dimension is set so that it does not interfere with the wagon W, the wagon W can be stored in the wagon storage area AW regardless of the depth of the back area 52. It becomes possible to increase the depth without worrying about interference.

In this embodiment, the top plate 2 can be moved up and down from the sitting position (D) used while sitting down to the standing position (U) used when standing up, so that it can be used in various ways. can correspond to

Note that the present invention is not limited to the embodiments described above.

For example, the bottom surface of the back area may be substantially horizontal, but if it is tilted as described above, the cord can be inserted and removed and handled smoothly.

The shape of the opening in the top plate is not limited to the above-described shape in which the unused end of the top plate is cut out, but may be in the shape of a window.

The left and right width dimensions of the cord duct can be set arbitrarily, but as long as they are smaller than the left and right width dimensions of the top board, a common cord duct can be used for top boards that have multiple width dimensions as described above. It becomes easier.

In the embodiments described above, the present invention is applied to a table whose top plate can be raised and lowered, but the invention may also be applied to a table whose top plate cannot be raised and lowered. Alternatively, the present invention may of course be applied to a device in which the top plate is tiltable relative to the top plate base.

In addition, various modifications may be made without departing from the spirit of the present invention.
