In consideration of the case where (2) is expanded and assembled, the portions colored in different colors for the engaging means (27, 28, 31) and the holding means (34) as described in claim 8 Can be included.

  The present invention also proposes a horizontal nesting type transport cart provided with a cover configured as described above. The transport carriage with a cover according to the present invention comprises a carriage body (3) having wheels (8) and a pair of front and rear erected from both front and rear ends of the carriage body (3). The cart body (3) includes side frames (4a, 4b), and the cart body (3) includes a loading platform (5) that is pivotably supported between an upright posture and a horizontal posture that overlap the inside of one side frame (4a). In the state where the loading platform (5) is in an upright position, the cart body (3) is placed inside the other side frame (4b) where the loading platform (5) of the conveying cart (1) that is outside does not overlap. In the transport cart (1) configured to be nested in a horizontal direction so that a part of the other side frame (4b) of the transport cart (1) to be inserted enters, a pair of front and rear of the cover (2) Of the side materials (15, 16), the side material (16) on the side where the top surface material (17) overlaps in the folded state of the cover (2) is the other side of the transport carriage (1). Installed inside (4b) , A top surface material (17) of the cover (2), a pair of left and right open / close surface materials (18, 19), and a side surface located inside the one side frame (4a) of the transport carriage (1). The cover (2) folded so that the material (15) overlaps each other inside the side material (16) positioned inside the other side frame (4b) of the transport carriage (1) is in a nesting state. It is configured to be located in a space formed between the other side frames (4b) in each transport carriage (1).

  According to the configuration of the present invention as set forth in claim 1, when the cover in the unfolded state covers the load storage space between the pair of front and rear side frames, when loading and unloading the load storage space, By opening the fastener from either side and rolling up the opening and closing face material, folding it appropriately in the direction of raising it and placing it on the top face material, the left and right side surfaces can be easily fully opened. However, the top surface material that supports the folded open / close surface material at this time is not a foldable one with a fold line as in the prior art, but it is in a single plate state, The weight of the supporting opening / closing face material in the folded state is restrained from being accompanied by deformation that hangs down along the fold line, which not only looks good, but also allows the entire rectangular side to be completely opened, allowing loading and unloading Easy It can be carried out.

  Moreover, when the cover is folded, just like when loading and unloading, the left and right open / close face materials are rolled up and folded on the outside (or inside) of the top face material, and then one of the side faces is attached. Rolled up in a state of being detached from one side frame of the transport carriage and overlaid on the inside (or outside) of the top surface material, and then, the folded opening / closing surface material and top surface material, and one side material What is necessary is just to make the whole hang down and to hold | maintain the whole face material which mutually overlaps finally in a hanging attitude | position by a holding means. In this way, all the face materials can be held compactly by being stacked inside the other side frame of the transport carriage. However, when the cover is folded, it is complicated as in the conventional case when the cover is folded. The folding of the cover is easy and quick because it is not necessary to be folded and only has to be folded at a simple folding line along the width direction of each face material. In addition, since the open / close face material and the top face material in the folded state are finally folded downward, the holding means for holding the cover in the folded state also has the face material raised upward in a vertical posture. Compared to the case where it must be held, simple work is required and workability is good.

  According to the second aspect of the present invention, when the cover is folded, when the one side member is lifted from the one side frame of the transport carriage and is superimposed on the top member, Thus, one of the side members can be held in a state where it is overlapped with the top member, so that the workability can be improved as compared with the case where such a state has to be held by hand. According to the third aspect of the present invention, the other side member that is not removed from the other side frame of the transport carriage even when the cover is folded is provided with the bag-like portion formed at the upper end of the other side member. Since the attachment position and shape with respect to the other side frame are determined simply by covering the upper end of the other side frame, the work of fastening both sides to the other side frame with a binding tool can be performed easily and easily.

  According to the configuration of claim 4, since the top surface material is held in a single plate state by the reinforcing plate-like body, the opening / closing surface material is wound on the top surface material during loading and unloading operations. There is no risk that the top surface will bend downwards and adversely affect the loading and unloading of the load when it is lifted and placed, and if it is a lightweight object, the load can be temporarily placed on the top surface. Easy to put in and out. In addition, when the cover is folded, the top surface material reinforced in a single plate state becomes the core material, so that the cover can be easily folded and the shape of the entire folded cover is determined beautifully and compactly. . In particular, the region of the one side member that overlaps the top member can be easily held in a single plate state by the reinforcing plate, and the cover can be easily folded more beautifully and compactly.

  Moreover, according to the structure of Claim 5, when folding both the left and right opening / closing face materials and stacking them on the top face material in order to fold the cover, the opening / closing face material on either side is finally folded. By utilizing the constituent member of the holding means located outside the folded face material that is on the outside, the entire face material that hangs down inside the other side face material can be easily held. In other words, the cover can be folded easily and quickly as compared with the case where the folding order of the left and right opening / closing face materials on the top face material is determined.

  Furthermore, according to the structure of Claim 6, compared with the case where the bottom part of the cover is open | released, the heat retention (heat insulation) and dustproof property by a cover can be improved, and especially a hook_and_loop | surface fastener is used as an engaging means. If used, it is possible to further enhance the heat retention (heat insulation) and dustproofness of the cover. In this case, according to the configuration of the seventh aspect, it is possible to hold the upright folded posture in which the bottom surface material of the cover is folded so as to overlap the inside of the other side surface material, so that the cover in the upright folded posture can be maintained. Compared to the case where you have to hang down the other face materials (a pair of left and right open / close face materials and one side face material) stacked on the inside and outside of the top surface material while holding the bottom surface material by hand. And the cover can be folded easily and quickly. Moreover, it is possible to reduce the cost by reducing the number of necessary engaging means. Further, according to the configuration of the eighth aspect, when the folded cover is unfolded and assembled in a situation where a plurality of engaging means and holding means are mixed, the engaging means and the holding means are engaged with each other. The pair of members to be worn can be easily and accurately recognized visually, and the cover can be deployed and assembled efficiently.

  In the case where a foldable cover having the above-described configuration is adopted for a conveyance trolley configured to be nestable in a horizontally nested manner as described in JP 2011-5970 A, a cover trolley with a cover is configured. According to the configuration described in Item 9, since the cover is folded and suspended inside the side frame on the opposite side to the side on which the loading platform is raised, of the pair of front and rear side frames of the transport carriage, it is disturbed by the folded cover. Without nesting the transport cart horizontally nested. In other words, it is not necessary to remove the cover itself from the transport carriage for nesting of the transport carriage, and the management of the cover is facilitated. In this case, the thickness of the entire folded cover is the same as when the trolley with no cover is nesting, so that the space between adjacent trolleys inside and outside is not increased due to the presence of the folded cover. In this case, it is possible to maintain the nesting efficiency of the transport carriage in the state without the cover even if nesting with the cover is kept by keeping it within the space between the side frames that are not adjacent to each other. As described above, the cover of the present invention has a structure that can be folded securely and compactly. Therefore, the transport cart provided with this cover does not reduce the nesting efficiency when nesting is performed with the cover attached. Easy to configure. In particular, as shown in the embodiments of the present invention to be described later, the folding lines for folding (for tri-folding) are provided on both the left and right opening / closing faces, so that both the left and right opening / closing faces can be easily, securely and compactly formed. Since it can be folded, it is effective as a constituent requirement of a transport carriage with a cover that does not reduce the nesting efficiency.

Expected cover effect on the space, for example, heat insulation (heat insulation) effect can be expected. When loading / unloading a load into / from the load storage space, an opening / closing surface material, such as an opening / closing surface material 18 (or an opening / closing surface material 19) on the side where the operator stands out of the pair of left and right opening / closing surface materials 18, 19. After opening the fasteners 22a, 22b (or fasteners 22c, 22d) on both sides upward, the lower side of the opening / closing face member 18 (or opening / closing face member 19) and the tongue on the bottom face member 20 side adjacent to the inside thereof In the state where the female surface fastener 23a and the male surface fastener 23b of the engaging means 27 that are engaged with the piece portion 26b (or the tongue piece portion 26c) are separated from each other, the opening / closing face member 18 (or opening / closing) The face material 19) may be rolled up and the left and right sides of the load storage space may be opened. Of course, the left and right sides of the load storage space can be opened as required. The opening and closing face members 18 and 19 raised upward can be placed on the top face member 17, but the top face member 17 is reinforced by a reinforcing plate-like body 29 to ensure a single plate state. Therefore, the top member 17 does not hang down due to the placement of the opening / closing members 18 and 19. In this way, it is easier to use if it is reinforced by the reinforcing plate-like body 29, but the opening / closing face member 18 (or the opening / closing face member 19) can be attached to the top face member 17 as described above even if not reinforced. It is possible to use it up.

  The cover 2 can be removed from the transport cart 1 by reversely performing the procedure for attaching to the transport cart 1 and pulling it upward from the pair of front and rear side frames 4a, 4b of the transport cart 1. 1B, it can be folded and held in a vertical posture inside the side frame 4b of the transport carriage 1. As shown in FIG. That is, as shown in FIG. 11, the pair of left and right opening and closing face members 18 and 19 are lifted upward and placed on the top face member 17 in the order described above. The opening and closing face members 18, 19 are folded in three at the positions of the folding lines 18a to 19b, and folded in a flat state of a size that just overlaps the top face member 17, so that the top face member 17 Stack in any order. Next, the female surface fastener 23a and the male surface fastener 23b of the engaging means 27 engaging the tongue piece 26a at the tip of the bottom surface member 20 and the lower side of the side member 15 are separated from each other. Then, the bottom member 20 is folded upward and overlapped inside the side member 16 as shown in FIG. At this time, the tongue pieces 26 a to 26 c on the free three side sides of the bottom member 20 are folded so as to overlap the inside of the bottom member 20, and the tongue piece 26 a at the tip of the bottom member 20 and the inner surface of the side member 16. Can be held in a folded position along the inside of the side member 16 by superimposing the female surface fastener 23a and the male surface fastener 23b of the engaging means 28 on each other. I can do it.

  Next, the female hook-and-loop fastener portion 24a and the male hook-and-loop fastener portion 24b in the tape-shaped hook-and-loop fastener 24 of the binding tool 33 that joins the lower end side of the side member 15 and the side frame 4a of the transport carriage 1 are engaged. As shown in FIG. 13, the side member 15 is lifted toward the lower side of the top surface member 17, and the upper region 15 a is stacked on the lower side of the top surface member 17, as shown in FIG. The side surface material 15 is in a state in which the lower region 15b of the side surface material 15 is suspended inside the side surface material 16 by superimposing and engaging the female surface fastener 23a and the male surface fastener 23b. 15 upper regions 15 a are engaged with the lower side of the top surface member 17. At this time, the upper region 15 a of the side member 15 is maintained in a single plate state by the reinforcing plate 30, so that the entire upper region 15 a of the side member 15 is placed below the top member 17. It can be easily overlapped and integrated with the top member 17 easily.

  Thereafter, the female hook-and-loop fastener portion 24a and the male hook-and-loop fastener portion 24b in the tape-shaped hook-and-loop fastener 24 of the binding tool 32 connecting the upper end side of the side member 15 and the side frame 4a of the transport carriage 1 are attached. As shown in FIG. 14, the top surface member 17 that supports the pair of left and right open / close surface members 18 and 19 that are folded in three on the upper side and that holds the upper region 15 a of the side surface member 15 on the lower side, It hangs down so as to overlap the inside of the side member 16. At this time, the lower region 15b of the side member 15 depending on the inner side of the side member 16 is sandwiched between the upper region 15a of the side member 15 and the side member 16 and overlaps the inner side of the side member 16. 20 is sandwiched between the side material 15 and the side material 16 in the folded state, but the lower half of the bottom surface material 20 is exposed downward from the side material 15 in the folded state. The tape-shaped male surface fastener 23b of the holding means 34 is attached to the bottom surface of the holding means 34. Finally, the tape-shaped male surface fastener 23b of the holding means 34 overlaps the outside of the top surface member 17. Of the opening and closing face members 18 and 19 that are folded in a folded manner, all the members constituting the cover 2 are overlapped and engaged with the female surface fastener 23a of the holding means 34 of the opening and closing face member that overlaps the outside. Face material 5-20 and in a folded state in approximately the same size as the side frame 4b of the conveyance carriage 1 can be held by the holding means 34 and along the inner side of the side frame 4b.

  In the state where the cover 2 is folded and held along the inside of the side frame 4b of the transport carriage 1 as described above, the cargo bed 5 is placed inside the side frame 4a on the side where the cover 2 in the folded state is not held. Can stand up. Of course, the lower end portion of the cover 2 that is folded and held inside the side frame 4b, that is, the lower end portion of the side member 16 and the one end portion of the bottom member 20 that overlaps the lower end portion are somewhat obstructive to lifting the loading platform 5. In such a case, prior to lifting the loading platform 5, the lower end of the side member 16 is released from the binding tool 25 that fastens the side frame 4 b, and the side member 16 described above is released. A lower end part and the one end part of the bottom face material 20 which overlaps this can be lifted. When the height of the side frames 4a, 4b (height of the side members 15, 16) is about 1.5 times larger than the length in the front-rear direction of the loading platform 5 (the top member 17) as in the illustrated embodiment. As shown in FIG. 1B, when the cover 2 is folded so as to overlap the inside of the side frame 4b, the side member 16 that overlaps the entire inside of the side frame 4b and the bottom member 20 that overlaps the inside of the side member 16 On the other hand, a group of face materials (the top face material 17, the folded left and right open / close face materials 18, 19 and the folded side face material 15) that are greatly swollen inward are arranged from the lower end of the side frame 4b. Since it is at a position that is raised by about 1/3 of the total height, the face material group that overlaps in a state of swelling greatly inside does not enter the lifting locus of the loading platform 5. At this time, when the side member 15 and the open / close face members 18 and 19 are accurately folded linearly along the folding lines 15c and 18a to 19b, the face material group (the top face member 17, the folded left and right open / close face members). 18, 19 and the folded side material 15) can be reduced in thickness, and the influence on lifting of the loading platform 5 can be reliably eliminated.

  The bottom material 20 of the cover 2 is not essential for the present invention. For example, if it is a cover as a measure against dust and rain, the bottom material 20 may not be provided. Moreover, although the nestable conveyance cart 1 provided with the loading platform 5 pivotably supported by the hoisting is shown as the conveyance cart 1, wheels are provided on the lower side of the loading platform 5 in place of the front-rear direction connecting member 7, and the loading platform is shown. The present invention can also be applied to a general transporting carriage in which side frames 4a and 4b are erected on both front and rear ends of 5. Furthermore, although hook-and-loop fasteners 25, 32, 33, engaging means 27, 28, 31 and holding means 34 are used, a pair of string-like bodies that can be fastened to each other, a combination of button holes and buttons, hook hooks, Various well-known items such as snaps can be used. Of course, even when these are used, at least one of the constituent members can be provided at the free end of the tape member having one end sewn on the cover.

  Further, when the reinforcing plate-like bodies 29 and 30 are used to configure the top region 17 and the upper region 15a of the side member 15 in a single plate state, the reinforcing plate-like bodies 29 and 30 are provided on the top surface. It may be attached to the inner side of the sheet material constituting the material 17 or the side material 15, and depending on the case, the upper region 15 a itself of the top surface material 17 or the side material 15 is constituted by reinforcing plate bodies 29, 30. It is also possible to do.

  In the above embodiment, when the cover 2 is folded, the left and right open / close face members 18 and 19 are described as folded on the top face member 17, but as shown in FIG. It is also possible to adopt a folding method in which 18 and 19 are folded under the top material 17 and overlapped.
