Description

    The present invention relates to a folding transport cart used for storage, transport, etc. of goods and packed products.

  Conventionally, there is a transport cart that can be folded and stored when stored in a warehouse or the like. As shown in Japanese Patent Application Laid-Open No. 2015-67205, this type of transport cart is provided with a bottom plate portion on which a transported article is placed so as to be superposed on the side wall portion, and one or both end wall portions are folded in the direction of the side wall portion. It is provided freely and is configured to be folded into an L shape or a flat plate shape.

  However, in the prior art, since the width of the transport cart after folding cannot be made smaller than the width of the side wall, there is a problem that the operability is inferior, such as being unable to be stored compactly and not being able to turn around.

FIG. 6 is a perspective view showing the folding transport cart 1 after the folding is completed.

  Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of a folding transport cart 1 according to the present invention. The foldable transport cart 1 is provided with a pair of end wall portions 5A and 5B standing on opposite edges of the bottom plate portion 3 on which the transported material is placed, and lower ends of the end wall portions 5A and 5B, respectively. A pair of side walls that connect the wheel 7 and each edge of one end wall 5A and the corresponding edge of the other end wall 5B of each of the pair of end walls 5A, 5B via a connector 19. It consists of 9A and 9B and has a substantially box shape.

  One end of the bottom plate portion 3 is attached to the lower end of the one end wall portion 5A via the rotary connector 21 so that the bottom plate portion 3 is rotatable in the vertical direction with respect to the one end wall portion 5A.

  The other end of the bottom plate portion 3 is provided with a lock function 27 that disables the rotation of the bottom plate portion 3 and is detachable with respect to the lower end of the other end wall portion 5B. The side end is detachable with respect to the lower end of one side wall portion 9A.

  The other side wall portion 9B of the pair of side wall portions 9A, 9B is detachable from the end wall portions 5A, 5B. As an example, the side wall portion 9B is fitted with a horizontal pipe receiver 17 provided with a plurality of horizontal pipes 15, 15... At the end portions in the vertical direction of the end wall portions 5A, 5B. The end walls 5A and 5B are detachable.

  One side wall portion 9A of the pair of side wall portions 9A and 9B is bent between the pipe frame 11A constituting the side wall portion 9A and the pipe frame 11B constituting the side wall portion 9A at the vertically bent portion 12. It is possible to bend in the direction of contacting and separating from the other side wall portion 9B through the tool 13.

The end wall portions 5A and 5B in the pair of end wall portions are rotatable in the horizontal direction with respect to the one side wall portion 9A.

  The end wall portions 5A and 5B and the side wall portions 9A and 9B of the foldable transport carriage 1 are formed by pipes as an example, but may be plate-like bodies or lattice-like bodies. The bottom plate portion 3 needs to be able to withstand the overload of the load to be transported, and is preferably formed of metal, synthetic resin, or the like. The wheel 7 is preferably provided with a wheel stop function in order to prevent the folding transport cart from moving during loading and unloading of luggage.

  FIG. 2 is an enlarged perspective view of a portion where the lock function 27 that disables the rotation of the bottom plate portion 3 of the folding transport cart 1 is provided. As an example, the bottom surface of the end portion of the bottom plate portion 3 includes a lock rod storage member 35, and the lock rod storage member 35 includes a lock rod 31 that can be moved forward and backward in a direction contacting and separating from the end wall portion 5 </ b> B. The lock rod 31 includes a knob 33 that is gripped when the lock rod 31 is advanced and retracted. A lock rod receiving portion 37 having a through hole corresponding to the lock rod 31 is provided at the bottom of the end wall portion 5B. When the lock rod receiving portion 37 slides the lock rod 31 in the direction in contact with the end wall portion 5B, the lock rod 31 penetrates the through hole of the lock rod receiving portion 37, and the bottom plate portion 3 cannot be rotated in the vertical direction. Become. On the other hand, when the lock rod 31 is slid in the direction away from the end wall portion 5B, the lock rod 31 is removed from the through hole of the lock rod receiving portion 37, so that the bottom plate portion 3 is moved in the vertical direction with the rotary connector 21 as a support shaft. Can be freely rotated.

(Folding procedure 1)
FIG. 3 is a perspective view showing a first procedure for folding the folding transport cart 1. By moving the horizontal pipe 15 constituting the side wall 9B upward, the horizontal pipe 15 is removed from the pipe holder 17, the lock rod 31 is slid away from the end wall portion 5B, and the lock rod 31 is moved away from the lock rod receiving portion 37. It removes from a through-hole, and makes the bottom plate part 3 rotatable freely with the rotation coupling tool 21 as a spindle.

(Folding procedure 2)
FIG. 4 is a perspective view showing a second procedure for folding the folding transport cart 1. By moving the end edge portion of the bottom plate portion 3 in the direction of the end wall portion 5B upward, the engagement between the locking plate 23 and the locking plate receiver 25 is disengaged, and the bottom plate portion 3 is connected to the rotating connector 21. It is rotated upward as a support shaft and is brought into close contact with the end wall portion 5A.

(Folding procedure 3)
FIG. 5 is a perspective view showing a third procedure for folding the folding transport cart 1. The pipe frame 11A constituting the side wall portion 9A and the pipe frame 11B constituting the side wall portion 9A are bent in the direction in which the side wall portion 9B is present via the bending tool 13, and the end of the pipe frame 11A constituting the side wall portion 9A. The pipe frame 11B and the end wall portion 5B constituting the wall portion 5A and the side wall portion 9A are respectively rotated via the connecting tool 19, and the end wall portion 5A, the pipe frame 11A constituting the side wall portion 9A, and the side wall portion 9A. Are folded so that the pipe frame 11B and the end wall portion 5B sequentially overlap.

  FIG. 6 is a perspective view showing the folding transport cart 1 that has been folded. The width of the foldable transport cart 1 after folding is smaller than the width of the side wall portions 9A and 9B, so that it can be folded compactly and can be stored in a narrow space.

  The end wall portions 5A and 5B and the side wall portions 9A and 9B can be reduced in weight by being formed of pipes, and can be further reduced in weight by using aluminum pipes, and can be provided with excellent operability. In order to facilitate the movement after folding, as an example, the folding transport cart 1 after folding is fixed in the horizontal direction with a wide string or the like provided with a hook-and-loop fastener, and the horizontal portion constituting the side wall portion 9B removed in the first procedure. It is preferable to store the pipe 15 between the end wall portion 5B and the pipe frame 11B constituting the side wall portion 9A.

The foldable transport cart 1 after being folded returns to the shape shown in FIG. 1 by performing the reverse procedure of the folding procedure.

  In addition, the end wall part of one folding trolley is made to adjoin the end wall part of one folding trolley, and the other folding folds about a plurality of folding transport carts that have been folded. A plurality of folding transport carts to facilitate movement, storage, etc., by connecting the end wall portions of the carriage to each end wall portion via a connecting metal or a wide string provided with a hook-and-loop fastener. Can be integrated.
