Description

  The present invention relates to a desk wagon with a height-adjustable top plate so that a part of the desk is placed under the top plate of a desk such as a flat table, more specifically, the top plate of the desk and the top plate of the wagon are the same. It relates to a desk wagon that is intended to be used face up.

  A table wagon with a top plate (hereinafter also referred to as a lift table) having a height adjustment function so that the top plate of the desk and the top plate of the wagon itself can be used on the same surface is disclosed in Patent Document 1. ~ 4 etc., and some are put to practical use.

  In known desk wagons, most of the top plates provided in the wagons are provided with a top plate having the same depth width as the depth (front-rear width) of the wagon. The reason is that if the top plate of the wagon is made larger than the depth of the wagon body (cabinet), the top plate will overhang from the depth (front / rear width) of the wagon. If you put your hand on it, the wagon may fall over. For this reason, in conventional desk wagons, the depth of the top plate (front / rear width) is adjusted to the front / rear width of the wagon so that the wagon will not fall over even if the end of the top plate is touched. -ing

  On the other hand, the wagon used under the top of the desk has the advantage that the top and the top of the desk can be used together, while the wagon main body is under the wagon. For this reason, the user feels that his / her feet are too narrow and the user's legs may touch the wagon, which is also difficult to use.

  In view of these points, the front / rear width of the wagon main body is formed small, while the front / rear width of the wagon top plate is increased, that is, by overhanging the front / rear width of the wagon main body, The area of the top plate that is coplanar with the top plate of the desk combined with the top plate is considerably enlarged, so it is clear that it is excellent in terms of usability, but it can be enlarged because of the above-mentioned falling problem. The current situation is not.

  Accordingly, an object of the present invention is to provide a desk wagon that solves the problem of the above-described overhang top plate in a known desk wagon, that is, the overturn problem of a desk wagon equipped with an overhang top plate.

The first configuration of the desk wagon of the present invention made for the purpose of solving the above-described problems is a desk wagon with a lifting / lowering top plate that can be used by storing a part of the wagon under the top of the desk. A fixing means that acts on the desk is provided on the plate, and the fixing means is formed by providing a fixing piece such as a wing or a rod on one end surface of the lifting table, and when the lifting table is raised, the fixing piece Is characterized in that it is pressure-bonded to the lower surface of the top plate of the desk .

The second configuration of the desk wagon of the present invention that can solve the above-described problem is that the desk top wagon with a lift top board that can be used by storing a part of the wagon under the desk top board, A fixing means that acts on the desk is provided , and the lifting means of the lifting table is formed by a screw type lifting mechanism that is built in from the side wall of the wagon and the marginal part of the partition wall and moves up and down by rotating in the reverse direction. It is characterized by .

In the present invention, in the above configuration, the lifting / lowering top plate of the wagon is formed to have a size or a planar shape overhanging from the wagon.

  At least the upper end portions of the left and right side walls of the wagon are connected by a ceiling connecting plate having a front and rear width narrower than the front and rear width of the wagon, and a blank portion is formed on the upper end surface of the wall. Thereby, the raising / lowering means can be arrange | positioned in the margin part of the said wall.

  Therefore, the raising / lowering means of the raising / lowering top plate in this invention can be formed with the screw-type raising / lowering mechanism built in the side wall of a wagon and the inside of a partition wall, and raising / lowering by reverse rotation.

  The present invention provides a desk wagon with a lifting table that can be used by storing a part of the wagon under the top of the desk. Since the lifting table is provided with fixing means that acts on the desk, the lifting table is arranged before and after the wagon. This wagon is overhanging from the width, and even if a load is applied to the overhanging part, this wagon will not fall. This advantage is also obtained in a desk wagon in which the front and rear width of the wagon body is formed small and an overhanging top plate is mounted.

  The fixing means is formed by providing a wing-shaped fixing piece on one side end surface of the elevating top plate, and when the elevating top plate is raised, the fixing piece is pressure-bonded to the lower surface of the desk top plate. Therefore, the structure is very simple and, therefore, the desk wagon can be firmly and securely fixed to the desk without causing any operation trouble or failure. The fixed piece may be formed by a rod-like body in addition to the wing-like body.

The front view of an example of the wagon for this invention desks. The top view of the wagon of FIG. The right view of the wagon of FIG. The front view of the use condition of the wagon of FIGS. The front view of another example of the wagon for this invention desks. FIG. 6 is a right side view of the wagon of FIG. 5.

  1 to 4, WD is a wagon for a desk according to the present invention. In this example, the wagon WD is a substantially rectangular bottom plate 1 and left and right side walls 2 and 3 erected on both left and right end portions of the bottom plate 1. And a partition wall 4 erected in the middle of the bottom plate 1 and a ceiling connecting plate 5 erected on the upper end portions of the walls 2 to 4 on the upper end surfaces of the walls 2, 3, 4. It is formed on the main body Wm. Note that the wagon body Wm in FIG. 1 is formed such that the front-rear width is smaller than the front-rear width (for example, 400 to 450 mm) of a normal-sized wagon body (as an example, moderately 250 to 390 mm). The present invention can be applied not only to a desk wagon in which the front-rear width of the wagon body is formed small, but also to a normal-size desk wagon. In addition, 6 is an intermediate shelf erected between adjacent walls at the intermediate height of the three walls 2, 3, 4. Whether the shelf 6 is fixed or movable is arbitrary, but in the example shown in the figure, it is fixed. Reference numeral 1a denotes casters provided at the bottom corners of the bottom plate 1.

  Here, the ceiling connecting plate 5 is substantially the same length (left and right length) as the bottom plate 1, but is formed by a plate-like body formed with a slightly narrower front-rear width (upper and lower widths in FIG. 2). Yes. Accordingly, when the ceiling connecting plate 5 is installed at the center (center) of each of the walls 2 to 4, blank portions where the plate 5 is not hung are formed on the upper and lower portions of the walls 2 to 4 in FIG. In this blank portion, a structure for raising and lowering a wagon top plate, which will be described later, is disposed.

  That is, since the ceiling connecting plate 5 is formed of each wall 2 to 4 of the wagon main body Wm, that is, a plate material having a width smaller than the front-rear width, a margin for accommodating the lifting mechanism L described later on each wall 2 to 4. Since the ceiling connecting plate 5 is narrow, there is an advantage that articles can be easily put in and out of the storage portion of the wagon body Wm.

  In the wagon WD of the present invention, using the above margins in the right side wall 3 and the partition wall 4, a screw type ascending and descending as an example of the vertical direction from the upper end surfaces of both walls 3, 4 to the wall thickness (inside). The mechanism L was accommodated at four places in the blank portion, and the top plate 7 was placed on and supported by the four lifting mechanisms L. Although not shown, the screw-type lifting mechanism is formed by a nut member fixed to the blank portion and a screw rod member that is screwed and rotated forward and backward by being screwed on the nut member, A top plate 7 of the present invention wagon WD, which will be described later, is supported on the upper end of the flange member.

  The top plate 7 has a width 7w in the vertical direction (in FIG. 2) larger than the front-rear width (upper and lower width in FIG. 2) w1 of the wagon body Wm, and the right and left widths 3 and the partition walls. The top plate member formed approximately the same as the outer dimension of 4 is supported on the lift table 7 in the wagon WD of the present invention by supporting almost four corners of the top plate member from the lower surface by the four lift mechanisms L. Yes.

  As shown in FIG. 4, the wagon WD of the present invention in which the lift table 7 is provided on the right half side of the wagon body Wm in FIG. It is placed under the top plate Dt, and the elevating top plate 7 is moved up and down so that the top surface of the top plate 7 is matched with the top surface of the top plate Dt. In the top plate Dt of FIG. 4, Dw is a wiring duct disposed on the lower surface of the top plate Dt. Further, a wire helmet holder (not shown) is provided on the outer surface of the left side wall 2 in the wagon WD of the present invention shown in FIG. It is optional whether or not to provide such incidental equipment in the wagon of the present invention.

  The above usage is the same as that of the conventional desk wagon. However, in the present invention wagon WD, when the front / rear width of the wagon main body Wm is formed small, the lifting table 7 is larger than the front / rear width of the wagon main body Wm. Since it will be in a larger overhanging state, when using it in a connected arrangement with the top plate Dt as described above, if you touch the overhanging part and apply a heavy load, this wagon WD will go beyond There is a risk of falling or tilting to the side or near side. The same applies to the case where the overhanging top plate 7 is mounted on the wagon body Wm having a normal size front and rear width.

  Therefore, in the present invention, when the lifting table 7 is moved up and down so that its surface matches the table top surface, the wagon WD of the present invention is fixed (locked) to the desk side simultaneously with the matching of both table surfaces. I did it.

  That is, in the illustrated example, a flat plate-like or wing-like fixing piece 8 protruding leftward is provided on the lower left side of the lift table 7 and the lower half side of the present invention wagon WD is placed with the lift table 7 slightly lowered. The table is placed under the table top Dt, and the end surfaces of the elevating table 7 and the table top Dt are brought into contact with each other. In this state, each elevating mechanism L is operated to raise the elevating top plate 7 so that the upper surface of the top plate 7 and the upper surface of the desk top plate Dt coincide with each other. At the same time, the upper surface of the fixed piece 8 becomes the top plate Dt of the desk. The wagon WD of the present invention is fixed to the desk (top plate Dt) by pressing the fixing piece 8 to the top plate Dt. The fixed piece 8 may be in the form of a bar or a fork claw other than a flat plate or wing.

  This effectively prevents the wagon WD from overturning or tilting even when a load is applied to the overhanging portion of the elevating table 7 or the like.

  In the wagon WD of the present invention, the storage portion formed in the wagon main body Wm is formed with openings for putting in and out goods on both sides of the partition wall 4. Left and right back plates 9 and 10 are attached to the surface which does not become the opening as illustrated in FIGS. 5 and 6. In the back plates 9 and 10, 9a and 10a are punching holes arranged for ventilation or as design accents. 5 and 6 are formed so that the upper and lower positions of the holes 9a and 10a can be reversed.

  On the other hand, unlike the examples of FIGS. 5 and 6, the example of the back plate shown in FIGS. 1 and 3 is such that the height of the back plates 91 and 101 is slightly larger than the height of the intermediate shelf 6 from the bottom plate 1. That is, a back plate formed with a low height. As shown in FIGS. 1 and 3, the short back plates 91 and 101 are provided symmetrically on the left and right with respect to the intermediate shelf 6 of the wagon body Wm. As a result, the part without the back plate 91 or 101 is open (opened) through the front and rear surfaces of the housing part of the wagon body Wm, so that access for putting in and out of the goods is possible from the front and rear surfaces. .

  The wagon of the present invention is as described above, and a desk wagon in which a part of the table is placed under the table top so that the table top and the table top are used on the same surface is provided on the table top. Since the wagon fixing means that acts on the desk is provided in the wagon, even if it is a wagon formed in a size (planar shape) that overhangs the lifting table from the wagon, the overhanging part is overloaded and falls over There is no such thing.

  In addition, the above-described wagon fixing means is formed by providing a fixed piece such as a wing shape on one end surface portion of the lifting table, and when the lifting table is lifted, the fixed piece is pressure-bonded to the lower surface of the table top. As a result, the structure is simple and, therefore, not only can it be easily manufactured and provided, but also it can exhibit a reliable and strong fixing function with very few failures.
