Description

  The present invention relates to a transport cart having a side panel for preventing collapse of cargo.

  In transport carts that run on casters and place luggage on a pallet (usually square or rectangular in plan view), side panels were provided to protect the luggage and prevent it from falling off the pallet (patented) References 1, 2).

  For example, a side panel is provided on two opposite sides of the four side surfaces and the other one side, and the remaining one side is used as a loading / unloading surface, and the loading / unloading operation is performed from the loading / unloading surface. Further, a side bar is also provided on this loading / unloading surface (the remaining one surface) for the purpose of preventing load collapse during traveling. On the other hand, in this type of transport cart, the transport cart is moved so that the loading / unloading surface faces the work position (Patent Document 1). In this case, the side panel may be configured to be detachable.

  In addition, side panels are provided only on two opposite sides of the four side surfaces, and the remaining two surfaces are used as the loading / unloading surfaces, and luggage is loaded and unloaded from the loading / unloading surfaces. In addition, side bars are provided on the loading and unloading surfaces (the remaining two surfaces) to prevent the collapse of the load during traveling.

  In general, in the case of a transport cart, in order to improve straight traveling performance, the pallet has a large aspect ratio in plan view (for example, the width direction is about a half of the length direction in the traveling direction). Was provided with a rotating shaft on the short side to undulate the pallet (Patent Document 3). In particular, it was used in so-called six-wheeled vehicles.

2. Use of the carriage 70

(1) In FIG. 1A, in plan view, the side on the first side panel 40A side is the A side, the outer edge 17 side of the first floor frame material is the C side, and the one end 13 side is the C1 side. The other end 14 side is defined as C2 side. Further, the side on the second side panel 40B side is set as B side, the outer edge 27 side of the second floor frame material is set as D side, the one end portion 23 side is set as D1 side, and the other end portion 24 side is set as D2 side.

(2) In the state (first state) shown in FIGS. 1 (a), 2 (a) and 2 (b), the transport carriage 70 can be used as a so-called balance carriage (six-wheel carriage). That is, since the lower end of the fixed caster 60 protrudes downward from the ground contact surface connecting the free casters 58, 58, a load is placed on the first and second pallets 40A, 40B and the direction indicated by the arrow 72 (first and second directions). It can go straight in the direction of the floor frame material 10, 20) and turn.
At this time, the first pallet 40A and the second pallet 40B are turned down, that is, the pallets 40A and 40B are substantially horizontal, the upper surface 40a of the first pallet 40A, the upper surface 40a of the second pallet 40B, and the third floor. Since the upper surface 31 of the frame member 30 is formed flush with the upper surface 31 (FIG. 2A), the first pallet 40A, the second pallet 40B, and the third floor frame member 30 are loaded in a well-balanced manner. it can.
At this time, similarly to a normal weighing carriage, the outer edge 17 side of the first floor frame material 10 and the outer edge 27 side of the second floor frame material 20, that is, the C surface (C1 side and C2 side) and the D side ( The luggage is taken in and out from the D1 side and D2 side (FIG. 1A).

(3) Further, the first side panel 50A is slightly raised to release the holding of the second support column 52 and the first holding recess 4A, and is rotated around the first support column 51 (rotating shaft recess 3). When the lower end portion of the second support column 52 is inserted and held in the second holding recess 4B of the first floor frame member 10, the first side panel 50A is positioned on the C1 side, and the load from the A side and the D1 side orthogonal to each other. Can be put in and out. Similarly, the second side panel 50B is lifted slightly to release the holding of the second support column 52 and the first holding recess 6A, and rotate around the first support column 51 (rotating shaft recess 5) to obtain the second When the lower end portion of the support column 52 is inserted and held in the second holding recess 6B of the second floor frame member 10, the second side panel 50B is positioned on the D2 side, and the loading and unloading of the luggage can be performed from the B side and the C2 side orthogonal to each other. (FIG. 1 (b), FIG. 3. Second position). In this case, it is also possible to rotate only one of the first side panel 50A and the second side panel 50B (not shown).

(4) Further, in the second position (FIGS. 1 (b) and 3), the first pallet 40A is rotated around the rotation shaft 46 from here and is raised along the first side panel 50A. Hold on. Similarly, the second pallet 40B is rotated around the rotation shaft 46, raised and held along the second side panel 50B (FIG. 1 (c), FIG. 4). In this state, the transport carriage 70 is H-shaped in plan view (FIG. 1C), and a large number of transport carriages 70a, 70b, 70c, 70d are replaced with the third floor frame material 30 of the other transport carriages. If the first floor frame material 10 or the second floor frame material 20 is passed through and stacked below, a large number of transport carts 70a, 70b, 70c, 70d are stored in a nested manner without taking up an area in plan view. Yes (Figure 5).
Further, when nesting with a conventional transport cart, if the wheel 59a of the free caster 58 hits the wheel 62 of the fixed caster 60 of another transport cart 70, the rubber wheels will come into contact with each other. 58 may be directed in a direction different from the traveling direction, but in this carriage 70, the fixed caster 60 is provided with the alignment cover 63, so that the wheels of the universal caster 58 hit the alignment cover 63 and are directly fixed to the fixed caster 60. The wheel 62 is not touched. Therefore, since it is possible to prevent the wheels 59a of the free casters 58 from bending in an unexpected direction, nesting and nesting can be efficiently performed.

3. Configuration of other transport cart 70

(1) In the above embodiment, the third floor frame material 30 is arranged so as to be orthogonal to the first floor frame material 10 and the second floor frame material 20, but the first floor frame material 10 (second floor frame material). 20), it can be arranged obliquely with a slight angle (FIGS. 6 to 10). Since the third floor frame material 30 can be slanted in a range that maintains an H shape in plan view with the first floor frame material 10 and the second floor frame material 20, the third floor frame material 30 and the first floor frame material 30 The angle θ formed by the floor frame material 10 is about 70 degrees at present (FIG. 6A), and is preferably 45 degrees or more from the strength of the entire floor frame 1 and the like.
In this case, in the first floor frame material 10, the distance (C1 side) between the position where the third floor frame material 30 is fixed and the one end portion 13 side where the rotation shaft concave portion 3 is provided is equal to the other end portion 14 side. It is desirable to set it to be wider (longer) than the distance (C2 side). In addition, the distance (D2 side) between the position where the third floor frame material 30 is fixed on the second floor frame material 20 and the other end 24 side where the rotation shaft recess 5 is provided is the distance from the one end 23 side. It is desirable to set it to be wider (longer) than (D1 side).
In this case, since the other configuration is the same as that of the above embodiment, the first side panel 50A is positioned on the A side and the second side panel 50B is positioned on the B side at the first position (FIGS. 6A and 7). In the second position, the first side panel 50A is positioned on the C1 side and the second side panel 50B is positioned on the D2 side (FIG. 6 (b), FIG. 8). Further, the first and second pallets 40A and 40B can be raised from the second position so as to be along the first and second side panels 50A and 50B, respectively (FIGS. 6C and 9). In this case, a large number of transport carts 70a, 70b, 70c, 70d are passed through the first floor frame material 10 or the second floor frame material 20 below the third floor frame material 30 of the other transport carts. If stacked, a large number of transport carts 70a, 70b, 70c, 70d can be stored in a nested manner without taking up an area in plan view (FIG. 10). In this case, since the third floor frame member 30 is disposed obliquely, the transport carriages a, 70b, 70c, and 70d can be combined into a rectangular shape in plan view (FIG. 10). Therefore, the storage space can be further reduced.

(2) Moreover, in the said embodiment, if the side panel 50 has the member (lower end part of the 1st support | pillar 51) used as a rotating shaft, and the member (lower end part of the 2nd support | pillar 52) used as a holding member, It can also be configured (not shown).
Further, in this case, the rotation shaft recesses 3 and 5 are changed in accordance with the member serving as the rotation shaft, and the configuration of the holding recesses 4A, 4B, 6A and 6B is also changed in accordance with the member serving as the holding member (FIG. Not shown).

(3) Further, in the above described embodiment, the length of the length of the third floor frame member 30 (i.e., the first second side panel 50A, the width of the 50B) _{L 1,} first second bed frame members 10 and 20 Assuming that L ₂ is “L ₂ > 2 × L ₁ ”, it is possible to rotate the first second side panels 50A and 50B beyond the third floor frame member 30.
L ₂ ≦ 2 × L ₁
