Description

  The present invention relates to a transport cart that can be nested, and relates to a transport cart that can be nested without folding side panels.

  In the carriage 40 provided with casters at the four corners and provided with the pallet 30 for loading the cargo and the side panels 12 and 13 for preventing the collapse of the cargo, a structure that can be nested to reduce the storage space when not in use is proposed. (Patent Documents 1 and 2).

  At this time, in one structure, the three panels 12, 13, 28 are arranged in a plane U shape, and the casters 10 are attached to the lower ends of the side panels 12, 13, respectively. In this case, the side panel 12, the back panel 28, and the plane I-shaped side panel 13 fixed in a plane L shape are rotatably connected, and the side panel 13 is overlapped with the plane L-shaped back panel 28 during nesting. (Patent Document 1, FIG. 7).

  In another structure, casters 10 are provided at the four corners of a flat U-shaped floor frame 1 that is narrow and closed on one side, and a fixed rear panel 28 is provided on the wide open side of the floor frame 1 so that a fixed rear surface is provided. Side panels 12 and 13 that pivot and fold on both sides of the panel 28 were provided (Patent Document 2, FIG. 8).

Further, in these transport carts 40, the side panels 12 and 13 are configured by arranging vertical and horizontal crosspieces in a lattice shape within a frame having a rectangular shape or a curved corner.
JP 2001-158362 A JP2002-19614

  In these transport carts 40, the side panels 12 and 13 overlap the back panel 28, and when traveling alone during nesting, there is no support in the direction of the arrow 51, and handling is necessary. Further, at the time of nesting, it is necessary to rotate and fold one or two side panels 12 and 13 without fail.

  However, according to the present invention, the side panel is formed from the column member and the panel main body inside the column member, and the panel main body is formed by arranging the oblique crosspieces having a predetermined shape in parallel.

That is, the present invention is a transporting carriage characterized in that a side panel is erected on a floor frame having casters and is configured as follows.
(1) The floor frame has a structure that allows nesting by overlapping with other carts in the same plane.
(2) Each of the side panels is formed substantially in parallel with the nesting direction, and includes a self-supporting column member and a panel body inside the column member.
(3) The panel body is formed by paralleling crosspieces arranged obliquely with respect to the nesting direction.
(4) In the horizontal rail member, a “height gap” was formed between the lower end of the upper horizontal rail member and the upper end of the lower horizontal rail member.

  Further, in the above, the transporting carriage is provided with a side panel in a direction substantially parallel to the nesting direction and a back panel in the nesting direction, and the relative position is fixed while the side panel and the back panel are mounted. Further, the floor frame is a transportation cart having a flat “C” shape, closed on the narrow side and disposed on the back side, and opened on the wide side and opened.

  In the above description, “fixing the relative position in the mounted state” includes a case where each can be attached and detached, but refers to a structure in which the relative position cannot be changed such as one approaching the other by rotation or the like in the mounted state.

  Since the side panel is composed of a self-supporting column member and a panel main body inside the column member, the side panel can have a simple structure in which the panel main body supports load collapse. In addition, the panel main body is arranged in such a manner that the horizontal beam members arranged obliquely with respect to the nesting direction are arranged in parallel, and the height between the lower edge of the upper horizontal beam material and the upper edge of the lower horizontal beam material is “high”. Since the “space in the vertical direction” is formed, the side panel can be overlapped in the plane of the side panel (in the vertical plane including the side panel) during nesting.

  On the floor frame 1 having the casters 10 and 10, the pallet 30 is disposed so as to be freely raised and lowered, and the side panels 12 and 13 are erected to constitute the transport carriage 40 (FIGS. 1 and 2).

  The floor frame 1 is formed in a plane “C” shape so that one side is the closed side 2 and the other side is the open side 2a, and the closed side of the floor frame 1 is connected to the open side 2a of the floor frame 1 of another carriage. 2 is inserted and overlapped on the same plane so that nesting is possible (FIG. 4A). A direction from the open side 2 a to the closed side 2 in the floor frame 1 is a nesting direction 52.

  Further, in the transporting carriage 40, the back panel 28 is erected on the closed side 2 of the floor frame 1 to be the rear face 41 side, and the open side 2a of the floor frame 1 is the opening face 42 side for taking out luggage (FIG. 1). (A)). With the side panels 12 and 13 and the back panel 28 attached, the relative position is fixed.

  The side panels 12 and 13 are formed substantially in parallel with the nesting direction, and are composed of a self-supporting column member 14 and a panel body 18 inside the column member 14. The column member 14 has a substantially inverted “U” shape in which the upper ends of the column vertical members 16 and 16a are connected by a column top member 17 (FIG. 2).

  The panel main body 18 is configured by side-by-side crosspieces 19 and 19 that are arranged obliquely on the vertical plane with respect to the nesting direction 52 (one end 20 is raised and the other end 21 is lowered). The horizontal crosspiece 19 has a “height gap H” between the other end (lower end 21) of the horizontal crosspiece 19B located above and one end (upper end 20) of the horizontal crosspiece 19A located below. Formed (FIG. 2). Therefore, in the nesting, the column members 14 and the column members 14 do not overlap with each other in the transport carts 40 and 40A, but the panel bodies 18 and 18 overlap in the same plane in the transport carts 40 and 40A. (FIG. 4).

  An embodiment of the present invention will be described with reference to FIGS.

1. Configuration of the carriage 40

(1) One side 4, 4 of the diagonal base material 3, 3 arranged in a plane “C” shape with one side narrow and the other side wide is connected by a connection base 6, In the vicinity of 4, a reinforcing base material 7 is installed in parallel with the connecting base material 6 to constitute the floor frame 1 (FIG. 3A). On the narrow side of the floor frame 1 (one side 4 of the diagonal base material 3), caster plates 8 and 8 having casters 10 attached to the lower surface are fixed between the connecting base material 6 and the reinforcing base material 7. Caster plates 9 and 9 attached with casters 10 are arranged on the lower surface of the wide side of the floor frame 1 (the other side 5 of the oblique base material 3). The caster plate 9 is fixed in advance to the lower surfaces of side panels 12 and 13 described later, and the caster plate 9 is fixed to the other side 5 of the oblique base material 3. In the floor frame 1, one side 4 (narrow side, back side) of the diagonal base material 3 is a closed side 2, and the other side 5 (wide side, opening side) of the diagonal base material 3 is an open side 2a (FIG. 3). (A)).

(2) On the floor frame 1, side panels 12 and 13 are erected above the diagonal base materials 3 and 3, respectively (FIGS. 1 and 2). The side panels 12 and 13 include a column member 14 in which the upper ends of two column vertical members 16 and 16 a are connected by a column top member 17, and a panel body 18 fixed to the column member 14. The caster plates 9 and 9 are fixed to the lower ends of the materials 16 and 16a, and the lower ends of the outer longitudinal members 23 of the panel body 18 are fixed on the connection base 6 (FIG. 2). The caster plates 9, 9 are fixed to the floor frame 1 as described above. The panel main body 18 includes an outer vertical member 23 and a crosspiece 19 fixed to the inner surface 14a of the column member 14. Further, the column member 14 is disposed on the “other end 5 side of the diagonal base material 3” (open side 2a, opening surface side) of the floor frame 1.

The crosspiece 19 is formed obliquely so that one end 20 (outer vertical member 23 side, back side) is raised and the other end 21 (column member 14 side, opening side) is lowered, and is parallel to the top and bottom. A large number of packages are arranged at intervals that prevent the package from going outside. In addition, a gap having a height H is formed between one end 20 of the horizontal beam member 19A positioned below and the other end 21 of the horizontal beam material 19B positioned above. That is,
・ "Height of one end 20 of the crosspiece 19A located below"
<"Height with the other end 21 of the crosspiece 19B located above"
(FIG. 2).

In addition, in order to be able to nest if more precisely defined (FIG. 4), in the case of the crosspiece 19 arranged obliquely with one end 20 raised and the other end 21 lowered,
・ "Height of the uppermost end of the one end 20 of the crosspiece 19A located below"
<"The height of the lowermost end of the other end 21 of the crosspiece 19B located above"
It becomes. Therefore, as long as this condition is satisfied, the structure of the crosspiece 19 is not limited to a hollow pipe or a bar, and the cross section is not limited to a circle, a square, or the like, and is arbitrary. For example, a strip-shaped plate (cross-sectional rectangle), various shaped steels reinforced with a strip-shaped plate (cross-section L-shape, cross-section C-shape, etc.) and the like can be employed (not shown). In general, round pipes, square pipes, and angle members (L-shaped cross section) are suitable.

  Further, the horizontal crosspieces 19 and 19 of the side panels 12 and 13 are formed substantially in parallel and the end 20a of the horizontal crosspiece 19 on the outer vertical member 23 side is on the inner side (side of the other side panel). ) And is connected to the outer longitudinal member 23.

(3) The inner vertical members 24, 24 are arranged side by side in the center between the outer vertical members 23, 23, and the lower ends of the inner vertical members 24, 24 are fixed to the connection base 6 of the floor panel 1. The upper end of the inner longitudinal member 24 on the side close to the outer longitudinal member 23 is connected by a transverse member 25 to form two frame shapes, respectively, and lattice-shaped front crosspieces 26 and 26 are attached inside each frame.

  As described above, the rear panel 28 is constituted by the outer longitudinal member 23, the inner longitudinal member 24, the transverse member 25, and the front crosspieces 26 and 26 (FIG. 1B). The back panel 28 (cross member 25) is located above the connection base 6 of the floor frame 1. In the rear panel 28, the side where the side panels 12, 13 are connected is referred to as an inner side 28a, and the other side is referred to as an outer side 28b.

(4) The pallet 30 is placed on the floor frame 1 and attached to the lower end portion of the back panel 28 (in the vicinity of the connecting base material 6) so as to be rotatable around a rotation shaft 31 formed in parallel with the connecting base material 6. The pallet 30 is on the floor frame 1 in a face-down state, and is raised by rotating about 90 degrees, and held on both sides of the pallet 30 with both side panels 12 and 13 to maintain the raised state. (FIG. 1 (a), FIG. 2). In this case, the both side panels 12 and 13 are locked inside the corresponding one end 20 of the crosspiece 19. The locked state of the pallet 30 is not limited to the case where the pallet 30 is locked between the crosspieces 19 and 19, but can be locked with an arbitrary structure using the side panels 12 and 13 and the back panel 28. (Not shown).

(5) A side bar 33 is installed between the columnar members 16a and 16a on the rear side of the column members 14 of the side panels 12 and 13, and one end 34 of the sidebar 33 is connected to the columnar member of the side panel 12 on one side. The other end 35 of the side bar is detachably locked to the other side panel 13 (FIG. 1B).

(6) The transport carriage 40 of the present invention is configured as described above (FIGS. 1 to 3). In the transport carriage 40, the rear panel 28 side (the closed side 2 of the floor frame 1, the narrow side) is opened on the rear face 41 of the transport carriage 40, and the side bar 33 side (the open side 2a of the floor frame 1, the wide side). It is set as the surface 42 (FIG. 1 (a), FIG. 2).

2. Use of the carriage 40

(1) With the pallet 30 faced down on the floor frame 1, from the opening surface 42 side, the side bar 33 can be attached / detached if necessary, and a load is placed on the pallet 30. Used for transporting luggage (FIGS. 1-2).

(2) When the transport carriage 40 is not used, it can be stored by nesting and reducing the plane space. At this time, the pallet 30 is raised and locked between the side panels 12 and 13 to maintain the state where the pallet 30 is raised (FIGS. 3A and 3B). In this state, the pallet 30 overlaps the back panel 28, but the side panels 12 and 13 are at the same position as when traveling, so the load distribution on the casters 10 and 10 hardly changes, and the transport cart 40 is placed on the back 41 side. The top can be prevented from tilting or falling down, and stable running is possible. At this time, the work can be carried out by holding the pillar members 14 and 14 from the opening surface 42 side of the transport carriage 40 and putting the body inside the floor frame 1, and working from the open side 2 a of the floor frame 1. A person can put his feet 44 and 44 and walk in the nesting direction, and can work safely and efficiently. Further, there is no need to move the panels 12, 13, 28 so as to change the relative positions, and it is not necessary to remove the panels 12, 13, 28.

When the pallet 30 is raised and the carriage 40 is stacked in the direction of the arrow 52 (nesting direction) from the opening surface 42 side of the other carriage 40A (FIGS. 3 and 4), the following (a) You can nest each other as in (c).
(a) The floor frame 1 enters from the opening on the opening surface 42 side of the other transport carriage 40A, and the outer side 3b of the diagonal base material 3 is the inner side 3a, 3a of the diagonal base material 3, 3 of the other transport truck 40A. Abut or approach. At this time, the connecting base members 6 and 6, the caster plates 8 and 8, and the caster plates 9 and 9 also come into contact with each other or approach each other (FIGS. 3A and 4A).
(b) Moreover, in the side panels 12 and 13, the column vertical member 16 on the back surface 41 side of the column member 16 approaches or abuts on the column member 16a on the opening surface 42 side of the other carriage 40A. Further, the lower surface side 19a of the oblique beam member 19 comes into contact with or approaches the upper surface side 19b of the oblique beam member 19 of the other transport carriage 40 (FIG. 3 (b), FIG. 4 (b)).
(c) Moreover, the outer surface 28a of the back panel 28 approaches the inner surface 28b (pallet side) of the other carriage 40A (FIGS. 3 and 4).

  In this case, any one portion may be in contact with the transportation carriages 40 and 40A. Generally, the floor frame 1 of the transportation carriage 40 is connected to the reinforcing base 7 of the floor frame 1 of the transportation carriage 40A. It is preferable that the base material 6 abuts.

  At this time, the side bar 33 can also be nested by hanging downward with the other side 35 unlocked (FIG. 4A).

(3) When canceling from the nesting state, the carriage 40 is pulled out, the pallet 30 and the side panels 12, 13 are unlocked and rotated, and the pallet 30 is simply placed on the floor frame 1, The transport state can be achieved without moving the panels 12, 13, and 28 (FIGS. 1 and 2).

(4) Moreover, in the said Example, since the back surface 41 side of the trolley | bogie 40 was obstruct | occluded and the opening surface 42 side was open | released by the floor frame 1, the operation | work at the time of nesting or nesting cancellation | release can be performed efficiently. Although it is preferable, the back surface 41 side of the carriage 40 can be opened (and wide), and the opening surface 42 side can be closed (and narrow) (not shown).

(5) Moreover, in the said Example, although the column member 14 comprised the column vertical members 16 and 16a and the column top material 17, if the column member 14 can become independent, the structure will not ask | require, For example, one piece It can also consist of a pillar material or a flat plate material (not shown).

(6) Moreover, in the said Example, the intermediate shelf 46 can also be provided (FIG. 5). For example, one end 47 of the intermediate shelf 46 is rotatably attached to the inner surface 28b of the back panel 28, and a member that receives the other end 48 of the intermediate shelf 46 is disposed between the column longitudinal members 16 and 16a of the column member 14 (FIG. 5). (A)). In this case, when the intermediate shelf 46 is used, it is used horizontally as shown by a chain line 46 in FIG. 5 (a), and when not used, the other end of the intermediate shelf 46 is used as shown by a solid line 46 in FIG. 5 (a). 48 is turned to the upper side to be in a vertical state, and is locked to the rear panel 28 (or sandwiched between the side panels 12 and 13) to maintain this state (FIG. 5A).
Similarly, the transporting carriage 40 can be nested from the opening 42 side of the transporting carriage 40A with the intermediate shelf 46 in a vertical state (FIG. 5B. In this case, the intermediate shelf of the transporting carriage 40A on the front side 46 is arranged between the outer surface 28a of the back panel 28 of the transport carriage 40.
Further, the intermediate shelf 46 can be detachable (not shown). In this case, the removed intermediate shelf 46 can be locked and accommodated along the outer surface 28a or the inner surface 28b or both surfaces of the back panel 28. In addition, when it is detachable, a rotation mechanism can be eliminated.
Further, the intermediate shelf 46 can be provided not only with one stage but also with many stages (not shown). Further, the intermediate shelf 46 may be formed in a tray shape that is installed between the side panels 12 and 13. Furthermore, when the intermediate shelves 46 are provided (particularly in the case of multiple stages), the pallet 30 can be omitted (not shown).

(7) Moreover, in the said Example, as for the horizontal beam member 19, the one end 20 (the outer vertical member 23 and the back panel 28 side. The back surface 41 side) goes up, and the other end 21 (the pillar member 14 side, the opening surface 42 side) ) Is formed so as to be lowered (FIG. 2), conversely, one end 20 (outer vertical member 23 / back panel 28 side, back 41 side) is lowered and the other end 21 (column member 14 side, opening). It can also be formed obliquely so that the surface 42 side is raised (Fig. 6 (b). In this case also, the other end 21 (the raised side) of the horizontal rail member 19A located below and the upper side A gap with a height H is formed between one end 20 (the lower side) of the horizontal rail member 19B positioned.
