  However, conventional carts simply place luggage on a square table and move the cart. It was very difficult to carry. Therefore, a cart that can carry such a difficult-to-carry baggage without falling is desired.

As a first means for achieving the above object, it comprises a cart body provided with a rectangular table for loading a load, and three or more wheels disposed on the back surface of the cart body, The gist of the invention is that a frame for leaning the luggage extending in the direction along the predetermined side on the upper surface of the table in the vicinity of the predetermined side of the table is detachably installed.
Accordingly, it is possible to carry a load that is difficult to carry without falling down by placing the load that is difficult to carry on the table top and leaning on the frame.
The reason why there are “three or more wheels” here is that if there are three wheels, they will be self-supporting. Four is better, and there may be five or more. Moreover, it is good to be what is called a caster offset from the center axis | shaft of a wheel. The “trolley body provided with the table” is the concept of the main body of the carriage provided with the table here, whether the table is stacked on the carriage body or the table and the carriage body are integrated.
The gist of the second means is that the frame is disposed as a pair of left and right in the vicinity of the predetermined sides facing each other, and at least one of the frames is detachable. That is, only one of the frames may be removed, or the structure may be such that both frames can be completely removed. “Left-right pair” is synonymous with front-rear pair depending on the viewing direction.
The gist of the third means is that the upper surface of the table is opened upward.
With such a structure, there is no height restriction when the luggage is leaned against the frame, and it is easy to place the luggage on the table.
The gist of the present invention is that the fourth means includes an elevating mechanism for elevating the table.
This is convenient because the table height can be changed to a suitable height in the work of loading or unloading a load on the table.

  In the cart of the present invention, it is possible to carry a load that is difficult to carry without falling down by placing the load that is difficult to carry on the table top and leaning on the frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the cart of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, the cart 1 includes a metal main body frame 2 as a cart body configured in a rectangular outer shape. The main body frame 2 has a skeleton composed of a vertical frame 3 arranged parallel to the left and right longitudinal direction and a horizontal frame 4 arranged so as to be orthogonal to the vertical frame 3 in the front-rear direction with respect to the vertical frame 3. . A reinforcing plate 5 is disposed on the bottom surface side of the horizontal frame 4. Brackets 6 that project outward are formed at positions near both ends of the left and right vertical frames 3. Casters 7 with stoppers are respectively fixed to the lower surfaces of these four brackets 6.

A table 8 having the same outer shape as that of the main body frame 2 (that is, a rectangular outer shape) is disposed on the main body frame 2. The table 8 can be moved up and down with respect to the main body frame 2 by a lifting mechanism 10. The elevating mechanism 10 includes a pantograph type parallel movement mechanism 11 and a hydraulic cylinder device 12.
As shown in FIG. 2, the parallel movement mechanism 11 is configured by arranging a link mechanism in which link members 13 are connected to each other in a crossing manner by a rotating shaft 14, and connecting these link mechanisms with a connecting frame 16. . The link mechanism is folded in a default state and is in a state of being horizontally stacked.
The link member 13 is rotatably connected to the back surface of the table 8 on the upper end side, and one of the link members 13 (on the cylinder body 15 side) is rotatably connected to the horizontal frame 4 on the lower end side. It is an open end without being connected.
As shown in FIG. 3, the hydraulic cylinder device 12 includes a cylinder body 15 and a lever handle device 17. The hydraulic cylinder device 12 is disposed so as to intersect the main body frame 2.
The rod 19 extending obliquely upward from the cylinder body 15 is connected to the connecting frame 16 of the translation mechanism 11, and the base side is attached to the mounting bracket extending downward from the body frame 2 (reinforcing plate 5). It is fixed to 20 via a mounting base 21. The lever handle device 17 includes a crank mechanism portion 22, and the drive pushes the oil feeding lever 24 through the crank mechanism portion 22 by moving the handle portion 23 downward. The handle portion 23 once lowered is returned by the action of the coil spring 18 disposed on the outer periphery of the oil feeding lever 24.
In such a configuration, in the elevating mechanism 10, when the handle portion 23 is manually pushed repeatedly, the oil moves in the hydraulic cylinder device 12 and advances the rod 19. The parallel movement mechanism 11 pushed by the advancement of the rod 19 moves the open end side of the link member 13 by the lever principle, and the link mechanism gradually deforms into an X shape to raise the table 8 (FIG. 2). State). On the other hand, when the table 8 raised to an arbitrary height is lowered, the moved oil is returned by operating a release valve handle (not shown) to retract the rod 19. As the rod 19 moves backward, the parallel movement mechanism 11 is folded again.

  A pair of left and right load-hanging pipe frames 25 are arranged along the longitudinal sides of the table 8. As shown in FIG. 1, each pipe frame 25 is inserted into two of the through holes 26 opened at the four corners of the table 8 that are spaced apart in the long side direction. A cylindrical guide surface 27 extending in the vertical direction is formed inside the through hole 26. The pipe frame 25 is constituted by a hollow metal pipe having a circular cross section, and the two vertical portions 25a arranged vertically on the table 8 and the horizontal portion arranged horizontally to connect between the vertical portions 25a. 25b and a substantially U-shape. The horizontal portions 25b are arranged in parallel with the left and right pipe frames 25 facing each other. As shown in FIG. 1, the lower end of the vertical portion 25 a is an insertion portion 25 c that is inserted into the through hole 26. A positioning flange 28 is formed at the boundary between the exposed vertical portion 25 a and the insertion portion 25 c accommodated in the through hole 26. The vertical portion 25a is about 1.5 times as long as the horizontal portion 25b. A rubber sheet 29 is disposed on the table 8 as a protective sheet that serves as a slip stopper and prevents damage to the luggage.

The cart 1 according to the embodiment having such a configuration has the following effects.
(1) When a tall, easy-to-fall thing or something that falls on its own is placed as a luggage on the table 8 of the carriage 1, it leans against the pipe frame 25 without falling down Can be transported.
(2) Since the pipe frame 25 has a sufficient length above, even a baggage with a height can be stood with good stability.
(3) Since the upper surface longitudinal direction of the table 8 between the pair of left and right pipe frames 25 is opened upward, the luggage is lowered onto the table 8 from above, or the luggage is moved along the longitudinal direction of the table 8. It is also possible to lower the bag while moving it, making it easier to load and unload luggage.
(4) Since the pipe frame 25 has the same shape on the left and right, the directionality in the longitudinal direction of the carriage 1 when moving or loading a load is lost (that is, either direction may be used), and it is not necessary to change the direction. Cheap.
(5) Since one or both of the pipe frames 25 can be removed from the table 8, it can be conveniently used in various patterns depending on the situation.

Note that the present invention can be modified and embodied as follows.
The configuration of the cart 1 is an example.
The table 8 may be integrated with the main body frame 2.
The carriage may not have the lifting mechanism 10.
-The shape of the pipe frame 25 may be other than the above. For example, in the above description, the pipe material is used for weight reduction, but the pipe material may not be used.
-In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
