Description

  The present invention relates to a desk carriage, and more particularly to a desk carriage that expands and contracts in two directions.

  Many existing desks do not have casters attached to their legs. For example, for sorting mail, a sorting shelf with an integrated sorting shelf for sending postcards / sealed fixed-size mail and non-standard-sized mail to the destination and sorting for delivery. An attached desk is used. Most conventional shelves with sorting shelves are not equipped with casters to move them, and these are still used today.

  In such a situation, it may be necessary to change the layout of the desk with shelves to cope with seasonal factors such as New Year's cards at the end of the year and temporary increases in mail due to recent business integration. is there. In addition, in a business office with a small building floor area, it is necessary to move a desk with a sorting shelf in order to secure a work space. However, as a matter of course, this sort shelf-equipped desk increases in weight by the sort shelf and lacks portability compared to a general desk, and increases in height by the sort shelf and lacks stability. For this reason, when it is necessary to move the desk, it is necessary to lift and move the desk by a plurality of people each time.

  In addition, for a foldable desk or the like, there are cases where a conveying means such as a carriage is used. However, because the desk dimensions are not uniform, if there are multiple types of desks, the transport means must be selected according to the desk dimensions, and the desks can be loaded on a hand-held carriage due to the dimensions. Sometimes it is not possible.

  An object of the present invention is to solve such a problem, and an object of the present invention is to provide a carriage that can easily transport a desk on which a moving means such as a caster is not provided.

In order to solve the above problems, a desk carriage according to the present invention is provided corresponding to a quadrangular frame whose four sides can be expanded and contracted, and at least the number of legs of the desk loaded on the frame. It has a bottom surface that is horizontal with respect to the floor surface at the same height position, and includes a leg accommodating portion that accommodates the leg of the desk inside, and casters provided at four corners of the frame.
Furthermore, in the desk carriage according to the present invention, each side of the frame body is constituted by two members that are nested.
Furthermore, in the table carriage according to the present invention, the bottom surface of the leg receiving portion is slightly higher than the ground contact surface of the caster in the height direction.
Furthermore, in the table carriage according to the present invention, the leg accommodating portion is located on the outermost side in the longitudinal direction and the short direction of the frame body.
Further, in the desk cart according to the present invention, the caster can be positioned on the inner side of the leg housing portion in the longitudinal direction and the short direction of the frame body.

  According to the trolley | bogie which concerns on this application, even if it is a desk to which the above casters are not attached, a desk of various dimensions can be conveyed easily.

FIG. 1 shows a table carriage 1 according to the present embodiment, where (a) is a front view and (b) is a plan view. FIG. 2 is a plan view of the table carriage 1 with the long side and the short side extended.

  With reference to FIG. 1, 2, the whole structure of the desk trolley | bogie 1 which concerns on embodiment of this invention is demonstrated. FIG. 1 shows a desk cart 1 according to the present embodiment, in which (a) is a front view and (b) is a plan view. FIG. 2 is a plan view of the table carriage 1 with the long side and the short side extended.

  A table carriage (hereinafter simply referred to as a carriage) 1 is a substantially rectangular frame, and is constituted by combining four T-shaped pipes 10, 20, 30, and 40 in which two rectangular pipes having a hollow cross section are assembled in a T shape. ing. The T-shaped pipes 10, 20, 30, and 40 are respectively the long side square pipes 10a, 20a, 30a, and 40a that form the long side of the frame, and the short side that forms the short side of the frame. The long side square pipes 10a, 20a, 30a, 40a are formed on the side surfaces of the short side square pipes 10b, 20b, 30b, 40b from the center in the axial direction as shown in FIG. Are coupled at positions slightly shifted in the outer direction of the carriage 1.

  Each T-shaped pipe 10, 20, 30, 40 is shown in FIG. 1 (b) from the position where the long side square pipes 10a, 20a, 30a, 40a of the short side square pipes 10b, 20b, 30b, 40b are attached. A substantially square shape that is chamfered at one location along the inner outer surface of the short parts 11, 21, 31, 41 protruding vertically and the outer outer surface of the long side square pipes 10a, 20a, 30a, 40a. Plate-shaped caster mounting plates 12, 22, 32 and 42 are provided. The caster mounting plates 12, 22, 32, and 42 are provided with casters 13, 23, 33, and 43 (shown by broken lines in FIG. 1B).

  The short side square pipes 10b, 20b, 30b of the short side square pipes 10b, 20b, 30b, 40b of the T-shaped pipes 10, 20, 30, 40 are respectively disposed on the short side portions 11, 21, 31, 41 side ends. , 40b are respectively provided at substantially the same height positions with bottomed rectangular tube-shaped leg accommodating portions 14, 24, 34, 44 extending vertically (vertical direction in FIG. 1A). The bottom surfaces of the leg accommodating portions 14, 24, 34, and 44 are substantially the same height at positions slightly higher than the floor surface when the casters 13, 23, 33, and 43 are placed on the floor surface. It is in a horizontal state, and is provided with holes 15, 25, 35, 45 at the center thereof (indicated by broken lines in FIG. 1 (a)). Further, the leg accommodating portions 14, 24, 34, 44 are arranged so as to be located on the outermost side in the longitudinal direction of the carriage 1 with respect to the T-shaped pipes 10, 20, 30, 40.

  The leg accommodating parts 14, 24, 34, 44 extend perpendicularly to the floor surface, and after assembling the carriage 1 as will be described later, it becomes possible to accommodate the lower end of the leg of the desk (not shown). Further, since the bottom surface is substantially horizontal, the desk can be stably loaded on the carriage 1 while in use. Further, it is possible to confirm whether or not the desk legs are in contact with the bottom surfaces of the leg accommodating portions 14, 24, 34, 44 through the holes 15, 25, 35, 45. In addition, in this Embodiment, although the leg accommodating parts 14, 24, 34, and 44 are made into the rectangular tube shape, it is not limited to this, What is necessary is just a shape which can accommodate the leg of a desk.

  Next, a method for assembling the carriage 1 will be described. The T-shaped pipes 10, 20, 30, and 40 of the carriage 1 are one of the long side square pipes 10 a, 20 a, 30 a, and 40 a and the short side square pipes 10 b, 20 b, 30 b, and 40 b, and the other is the outside. Thus, they are combined in a nesting manner that can slide with respect to each other (in FIGS. 1 and 2, the invisible portions of the inner pipe are indicated by broken lines). More specifically, in FIG. 1B, the long side square pipe 10a is the long side square pipe 40a, the short side square pipe 40b is the short side square pipe 30b, and the long side square pipe 30a is the long side square. The short side square pipe 20b is inserted into the short side square pipe 10b in the pipe 20a.

  Among the T-shaped pipes 10, 20, 30, 40, the long side square pipes 10a, 20a, 30a, 40a and the short side square pipes 10b, 20b, 30b, 40b are pipes that are outside when they are combined. Specifically, the pressing fixtures 16, 26, 36, 46 are attached to the inner end portions of the outer surfaces of the long side square pipes 20a, 40a and the short side square pipes 10b, 30b. The fixtures 16, 26, 36, and 46 turn the screws so that the pipes that are inside when they are combined, specifically, the surfaces of the long-side square pipes 10a and 30a and the short-side square pipes 20b and 40b, are formed. The long side square pipes 10a, 20a, 30a, 40a and the short side square pipes 10b, 20b, 30b, 40b are fixed so as not to move relatively.

  Since each of the T-shaped pipes 10, 20, 30, 40 is nested as described above, the long side square pipes 10a, 20a, 30a, 40a and the short side square pipes 10b, 20b, 30b, 40b are slid. Thus, the long side and the short side of the carriage 1 can be expanded and contracted. As a procedure, after loosening the fixtures 16, 26, 36, 46, the long side square pipes 10a, 20a, 30a, 40a and the short side square pipes 10b, 20b, 30b are matched to the size of the desk placed on the carriage 1. , 40b may be slid and the fixtures 16, 26, 36, 46 may be fastened and fixed again. In FIG. 2, for example, the cart 1 in a state in which the sides on the long side and the short side are extended from the state shown in FIG.

  In the present embodiment, the carriage 1 is a rectangular frame, and the T-shaped pipes 10, 20, 30, and 40 are formed of square pipes having different lengths. However, the shape of the carriage is not limited to this, for example, A square frame may be used, and the T-shaped pipes 10, 20, 30, and 40 may be formed of square pipes having the same length. Further, the T-shaped pipes 10, 20, 30, 40 are nested so that the carriage 1 can be expanded and contracted, but the long side square pipes 10a, 20a, 30a, 40a and the short side square pipes 10b, 20b, 30b, It is good also as a slide structure which piles up 40b up and down.

  In the cart 1 according to the present embodiment, the sides on the long side and the short side can be expanded and contracted, so that one cart can correspond to desks of various widths and depths.

  Since the carriage 1 is provided with the leg accommodating portions 14, 24, 34, 44 as described above, the desk can be stably loaded on the carriage while it is in use and transported, and can be used as it is. In addition, since the bottom surfaces of the leg accommodating portions 14, 24, 34, 44 are only slightly higher than the floor surface, the height of the desk is almost the same as when the desk is not loaded on the carriage 1, It will not interfere with the work on the desk.

  In particular, in the present embodiment, the bottom surfaces of the leg accommodating portions 14, 24, 34, and 44 are slightly higher than the ground contact surfaces of the casters 13, 23, 33, and 43 in the height direction. It is close to the height. Therefore, compared with the height of the original desk, there is almost no change in the height of the desk even when placed on the carriage 1. For example, in the case of a desk with a sorting shelf, the sorting shelf can be maintained at a height close to the original height that workers are accustomed to. Therefore, even if the desk is placed on the carriage 1, work efficiency can be improved. There is no deterioration.

  As described above, the leg accommodating portions 14, 24, 34, 44 are arranged on the outermost side in the longitudinal direction and the short direction with respect to the carriage 1. The casters 13, 23, 33, and 43 are located on the inner side in the same direction as the longitudinal outer end portions (leg accommodating portions 14, 24, 34, and 44) of the carriage 1 and in the lateral direction outer end portions (legs). The housings 14, 24, 34, 44) can be located inside in the same direction. Thereby, when arranging a plurality of desks placed on the carriage 1 in a state of being in contact with each other, it is possible to prevent a situation in which the carriages 1 interfere with each other and interfere with this.
