Description

[Technical Field]

[0001] The present invention relates to a flat plate carrier that can easily transport heavy plate-like objects, and more specifically, to an assemblable flat plate carrier that can be attached to a cart and can easily transport heavy plate-like objects while attached to the cart. [Background technology]

[0002] Due to their shape, heavy plate-like materials such as Alpolic, straw board, and aluminum office partitions, as well as glass, sashes, plywood, panels, concrete panels, and boards, cannot usually be loaded onto a standard cart. Even if they could be loaded, the cart becomes unstable, making them difficult and dangerous to transport. Furthermore, the cart takes up too much space, and the materials and cargo become unstable, making it difficult to proceed with work as planned. In the worst case scenario, there is a risk of the plate-like material being hit against a wall or pillar, causing damage, or even the cart or plate-like material protruding from the cart hitting a person during transport. For this reason, heavy plate-like materials are sometimes unavoidably transported by hand, resulting in time-consuming, labor-intensive, and inefficient work.

[0003] As an apparatus for efficiently transporting the above-mentioned heavy plate-like objects, for example, Patent Document 1 (Patent No. 7277882) discloses a flat plate carrier attached to a dolly. The flat plate carrier disclosed in Patent Document 1 is characterized by having a rectangular flat plate leaning frame that forms an angle of 50° to 85° with the upper surface of the dolly when the flat plate carrier is attached to the dolly, a rectangular flat plate support frame that is connected to the lower side of the upper surface of the flat plate leaning frame and fixed at an angle of 80° to 110° with respect to the upper surface of the flat plate leaning frame, and a pair of fixing frames that are attached to the front and rear ends of the lower surface of the flat plate leaning frame and fix the flat plate carrier to the upper surface of the dolly.

[0004] By using the flat plate carrier disclosed in Patent Document 1, heavy plate-shaped objects can be transported safely and efficiently, thereby reducing the time required for manual work. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7277882 Summary of the Invention [Problem to be solved by the invention]

[0006] The flat plate carrier disclosed in Patent Document 1 requires that each frame be removed and attached when in use, but there are concerns that it may become difficult to know which frame should be attached to which location, or that parts of the frame may be lost when removed. Therefore, the present inventors worked on developing a flat plate carrier that can be used as a flat plate carrier simply by assembling the frames, without the need to attach and remove them, and found that this problem can be solved by combining a frame with a round cross-section and a frame with a rectangular cross-section that is attached to the outside of the round cross-section frame.

[0007] However, the inventors discovered a new problem in that changing the configuration of the frame material in this way weakens the strength of the connection between the flat plate leaning frame and the flat plate support frame, causing the flat plate support frame to sway upward or rattle when a single flat plate is placed on the flat plate leaning frame.

[0008] The present invention has been made in consideration of these circumstances, and its purpose is to provide an assemblable flat plate carrier that can prevent the flat plate support frame from swaying upward or rattling when a single flat plate is placed on the flat plate leaning frame. [Means for solving the problem]

[0009] After extensive research into the above-mentioned problems, the inventors discovered that the above-mentioned problems could be solved by changing the positional relationship between the flat plate support frame and the flat plate leaning frame before and after assembly, and thus completed the present invention described below.

[0010] In other words, the assemblable flat plate carrier of the present invention is attachable to a cart, can transport a flat plate leaned at an angle, and can be assembled. The flat plate carrier of the present invention is configured to have, when the assemblable flat plate carrier is attached to a cart, a rectangular flat plate leaning frame that forms an angle of 50° to 85° with respect to the upper surface of the cart, rectangular flat plate support frames that are connected to both ends of the flat plate leaning frame and fixed at an angle of 80° to 110° with respect to the upper surface of the flat plate leaning frame, a fixed frame that is attached to the underside of the flat plate leaning frame and fixes the flat plate carrier to the upper surface of the cart, and two flat plate support frame fixing parts that are attached, one to each end of the connecting part between the flat plate leaning frame and the flat plate support frame, and that pivotally support a movable frame that constitutes one side of the flat plate support frame, The flat plate support frame fixing portion can pivotally support the movable frame so that the movable frame can move below the lower end of the flat plate leaning frame.

[0011] The assemblable flat plate carrier of the present invention does not require the attachment or detachment of each frame, and can be made into a flat plate carrier simply by assembling each frame, so there is no risk of losing track of the attachment positions of each frame or losing a frame. The assemblable flat plate carrier of the present invention is attached to a cart using a fixed frame, so that the plate leaning frame forms an angle of 50° to 85° with respect to the top surface of the cart. In this state, the bottom of a plate can be placed on the plate support frame and the surface of the plate leaned against the plate leaning frame, allowing the plate to be stably loaded onto the plate carrier. Furthermore, by setting the angle between the plate leaning frame and the plate support frame to be 80° to 110°, the surface of the plate can easily abut against the plate leaning frame when the bottom of the plate is in contact with the plate support frame, preventing the plate from wobbling when transported on the cart. Furthermore, the fixed portion of the plate support frame is configured to pivotally support the movable frame so that it can be moved below the lower end of the plate leaning frame. Therefore, after assembly, the end of the movable frame, i.e., the plate support frame, can be positioned below the lower end of the plate leaning frame. This prevents the plate support frame from swaying upward or rattling even when a plate is placed on the plate leaning frame. Moreover, the plate carrier of the present invention is made of separate parts from the cart and can be stored compactly without removing the frames, so when plates are not being transported, the plate carrier can be removed from the cart and is easy to carry.

[0012] In the above configuration, it is preferable that the flat plate support frame fixing portion is a member having an S-shaped through hole formed therein for movably supporting the movable frame. By having the flat plate support frame fixing portion be a member having an S-shaped through hole formed therein for movably supporting the movable frame, the position of the flat plate support frame can be changed by sliding the movable frame before and after assembly, making assembly easier, and the movable frame can be easily fixed to both ends of the S-shaped through hole, making it possible to stably fix the flat plate support frame before and after assembly.

[0013] In the above configuration, the plate support frame fixing portion preferably has a pre-assembly through-hole for fixing an end of the movable frame in a position before the plate carrier is assembled, a post-assembly through-hole for fixing an end of the movable frame in a position after the plate carrier is assembled, and an S-shaped connecting hole that connects the pre-assembly through-hole and the post-assembly through-hole and allows the movable frame to move. By providing a pre-assembly through-hole for fixing the movable frame in a position before the plate carrier is assembled, it is possible to prevent the plate support frame from swinging when the plate carrier is carried in its compact pre-assembly state. Furthermore, by providing a post-assembly through-hole for fixing the end of the movable frame in a position after the plate carrier is assembled, it is possible to further prevent the plate support frame from swaying upward or rattling even when a plate is placed on the plate leaning frame after assembly, thereby further improving the stability of the plate being transported. In addition, by having an S-shaped connecting hole that connects the pre-assembly through hole and the post-assembly through hole and allows the movable frame to move, the position of the flat plate support frame can be changed by sliding the movable frame before and after assembly, making assembly easier.

[0014] In the above configuration, the fixed frame preferably includes a rectangular bogie abutment frame attached to the upper surface of the bogie and a support frame fixed to the bogie abutment frame and supporting the underside of the flat plate leaning frame from below. By providing a rectangular bogie abutment frame attached to the upper surface of the bogie in this manner, the flat plate carrier can be more firmly fixed to the bogie. Furthermore, by providing a support frame fixed to the bogie abutment frame and supporting the underside of the flat plate leaning frame from below, rattle of the flat plate leaning frame can be prevented, further improving stability when a flat plate is placed on the bogie. [Effects of the Invention]

[0015] The assemblable flat plate carrier of the present invention prevents the flat plate support frame from swaying upward or rattling when a single flat plate is placed on the flat plate leaning frame, thereby providing excellent stability for the flat plate being transported. Furthermore, the flat plate carrier can be constructed by simply assembling the frames, without the need to attach or detach each frame. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] A preferred embodiment of the present invention will be described below with reference to the drawings. The embodiment described below is merely an example of the present invention, and the embodiment of the present invention can be appropriately modified without departing from the spirit and scope of the present invention.

[0018] Fig. 1 is a perspective view from diagonally behind of a flat plate carrier 1 of the present invention attached to a cart 6, Fig. 5 is a perspective view from diagonally front of the flat plate carrier 1 of the present invention attached to the cart 6, and Fig. 3 is a perspective view showing a state in which a heavy load such as a flat plate 7 is loaded on the flat plate carrier 1 of Fig. 1. Figs. 2 and 4 are front views of Figs. 1 and 3, respectively. The flat plate carrier 1 of the present invention is attached to a cart 6 for use, and is composed of a flat plate leaning frame 2, a flat plate support frame 3, a fixed frame 4, and flat plate support frame fixing parts 5 attached to both ends of the connection between the flat plate leaning frame 2 and the flat plate support frame 3.

[0019] (Flat leaning frame) As shown in FIGS. 1 to 5 , the flat plate leaning frame 2 is a portion against which the flat plate 7 leans when a heavy load of the flat plate 7 is loaded, and is formed in a U-shape by combining metal frames. The flat plate leaning frame 2 has a U-shaped base frame 21 and a U-shaped extension frame 22 attached to the upper surface of the base frame 21. The lower end of the flat plate leaning frame 2, i.e., the lower ends of the base frame 21 and the extension frame 22, are fixed to the upper end of the flat plate support frame fixing portion 5. As shown in FIG. 1 , when the flat plate carrier 1 is attached to the dolly 6, the flat plate leaning frame 2 is fixed to the dolly 6 so as to form an angle of 50° to 85° with respect to the top plate 61 of the dolly 6. By fixing the flat plate leaning frame 2 to the dolly 6 at such an angle, the flat plate 7 can be loaded so as to lean against the flat plate leaning frame 2, as shown in FIG. 4 , improving the stability of the flat plate 7 when the dolly is in operation. In this specification, the upper surface of the flat plate leaning frame 2 refers to the surface on the flat plate support frame 3 side, and the lower surface of the flat plate leaning frame 2 refers to the surface on the fixed frame 4 side (the right side in Fig. 2). In addition, in this specification, the lower side refers to the side approaching the cart 6 when the flat plate carrier 1 is mounted on the cart 6, and the upper side refers to the side away from the cart 6. Furthermore, the front side (or forward) refers to the flat plate support frame 3 side (the left side in Fig. 2) when the flat plate leaning frame 2 is used as the reference, and the rear side (or rearward) refers to the fixed frame 4 side (the right side in Fig. 2) when the flat plate leaning frame 2 is used as the reference.

[0020] As shown in Figures 1, 2, and 5, the telescopic frame 22 has two metal frames on its two sides, each containing a smaller metal frame, with the upper ends of the two smaller metal frames connected by a single metal frame. The smaller metal frame can be pulled out and fixed in place, allowing the vertical length of the plate leaning frame 2 to be adjusted. If the plate 7 to be transported is large, adjusting the vertical length of the telescopic frame 22 allows the plate leaning frame 2 to be adjusted to a size that allows the plate 7 to stably lean against it. As shown in Figures 3 and 4, the vertical length of the plate leaning frame 2 is preferably at least 60% of the vertical length of the plate 7 to be transported.

[0021] 1, 2, and 5, the extendable frame 22 is provided with two plate support frame fastening portions 211 at the upper ends of each of its two side edges, which can fasten (or secure) the flat plate support frame 3 in a folded state before assembly. Here, FIG. 7 is a perspective view of the flat plate carrier 1 of FIG. 5 in a state in which the flat plate support frame 3 and leg members 32 are folded, and FIG. 9 is a perspective view from diagonally behind, showing a state in which the flat plate leaning frame 2 has been further stored from the state of FIG. 7. As shown in FIG. 7, the two plate support frame fastening portions 211 each have a protrusion 212 at its lower end, and the flat plate support frame 3 described below has a hole 33 at the tip of the metal frame on each of the two side edges (the tip opposite the plate support frame fixing portion 5). 7 and 9, the flat plate leaning frame 2 can be stored by folding the flat plate support frame 3, shortening the length of the extendable frame 22, and inserting the protrusions 212 into the holes 33. By storing it in this state, the flat plate leaning frame 2 can firmly fasten (or fix) the folded flat plate support frame 3, which further prevents the flat plate support frame 3 from wobbling when carrying the flat plate carrier 1, making it easier to carry.

[0022] (Flat plate support frame) As shown in Figures 1 to 5, the flat plate support frame 3 is rectangular and is provided to support the bottom of a heavy flat plate. One side of the rectangle is formed by a movable metal frame 31 with a round cross section, and the remaining three sides are formed by a U-shaped metal frame with a rectangular cross section. A rectangular metal plate is attached to the inside of the rectangular metal frame, and to improve the load-bearing capacity of the flat plate support frame 3, further metal frames are attached that connect the metal plate to the side sides of the U-shaped metal frame.

[0023] In this embodiment, the flat plate support frames 3 are attached to both ends of the U-shaped flat plate leaning frame 2 at an angle of 90° relative to the upper surface of the flat plate leaning frame 2 using flat plate support frame fixing parts 5, which will be described later. As shown in Figures 3 and 4, a heavy flat plate load is loaded onto the flat plate support frame 3 with the surface of a flat plate 7 leaning against the flat plate leaning frame 2. As shown in Figures 1, 2, and 5, the flat plate leaning frame 2 is assembled so that the angle formed by the surface of the flat plate leaning frame 2 (the surface of the extension frame 22) and the surface of the flat plate support frame 3 is 90°. Therefore, when a heavy flat plate 7 loads on the flat plate support frame 3, a gap is unlikely to occur between the flat plate 7 and the flat plate leaning frame 2, and rattle during operation of the cart 6 can be prevented. In this embodiment, the angle between the surface of the flat plate leaning frame 2 and the surface of the flat plate support frame 3 is described as 90° (i.e., perpendicular), but 90° is not essential, and the surface of the flat plate support frame 3 relative to the upper surface of the flat plate leaning frame 2 may be fixed at an angle of, for example, 80° or more and 110° or less, preferably 85° or more and 100° or less.

[0024] 2 and 5, in this embodiment, leg members 32 for supporting the flat plate support frame 3 are attached to both ends of the underside of the rectangular flat plate support frame 3. As shown in FIG. 2, the leg members 32 are formed so that when the angle between the surface of the flat plate leaning frame 2 and the surface of the flat plate support frame 3 is 90°, the underside of the leg members 32 (the surface opposite to the flat plate support frame 3) comes into close contact with the surface of the cart 6. This allows the flat plate support frame 3 to be supported more stably, and therefore, when a heavy object such as a flat plate 7 is loaded on the flat plate support frame 3, rattling of the flat plate carrier 1 can be more effectively prevented.

[0025] As shown in Fig. 7, in this embodiment, the flat plate support frame 3 can be rotated and folded toward the flat plate leaning frame 2. The two leg members 32 can be rotated so that they face each other and stored under the flat plate support frame 3. Therefore, with the flat plate carrier 1 fixed to the cart 6 by the fixing frame 4, it can be easily moved by the cart 6 even in narrow passages or on scaffolding. Note that in this embodiment, two leg members 32 are attached, but the number of leg members is not limited as long as they can support the flat plate support frame 3, and may be, for example, one to four.

[0026] (Flat plate support frame fixing part) 1 to 5, in this embodiment, a total of two flat plate support frame fixing parts 5 are attached to both ends of the connection part between the flat plate leaning frame 2 and the flat plate support frame 3. FIG. 6 is an enlarged view of the flat plate support frame fixing part 5 in FIG. 5. As shown in FIG. 6, the flat plate support frame fixing part 5 is a hollow rectangular parallelepiped member with S-shaped through holes 51 formed in the centers of two opposing faces, and these S-shaped through holes 51 movably support a movable frame 31 with a round cross section that forms one side of the flat plate support frame 3. In this embodiment, the S-shaped through-hole 51 includes a pre-assembly through-hole 511 that secures the end of the movable frame 31 in a position before the flat plate carrier 1 is assembled, a post-assembly through-hole 512 that secures the end of the movable frame 31 in a position after the flat plate carrier is assembled, and an S-shaped connecting hole 513 that connects the pre-assembly through-hole 511 and the post-assembly through-hole 512 and allows the movable frame 31 to move. The pre-assembly through-hole 511 is located in the front portion (flat plate support frame 3 side) of the flat plate support frame fixing portion 5, and the post-assembly through-hole 512 is located in the rear portion (fixed frame 4 side). The lower end of the flat plate leaning frame 2 is attached to the upper portion of the post-assembly through-hole 512. Both ends of the movable frame 31 are formed with thin cylindrical pieces that are too large to fit into the S-shaped through-holes 51, so that the movable frame 31 can be pivotally supported in the S-shaped through-hole 51 without coming off. As shown in FIG. 6 , after assembly, the movable frame 31 is pivotally supported in the through-holes 512, allowing the movable frame 31 to be positioned below the lower end of the flat-plate leaning frame 2; that is, the end of the flat-plate support frame 3 can be positioned below the lower end of the flat-plate leaning frame 2. Here, "lower" refers to the side perpendicular to and closer to the top plate 61 when the flat-plate carrier 1 is mounted on the cart 6. For example, as shown in FIG. 2 , "below the lower end of the flat-plate leaning frame 2" refers to the side perpendicular to the top plate 61 from the lower end of the flat-plate leaning frame 2. This feature prevents the flat-plate support frame 3 from swaying upward or rattling, even when a single flat plate 7 is placed on the flat-plate leaning frame 2, thereby improving the stability of the transported flat plate 7. Furthermore, since the movable frame 31 is firmly fixed in the through-holes 512 after assembly, the stability is even more pronounced.

[0027] FIG. 8 is an enlarged view of the flat plate support frame fixing portion shown in FIG. 7. As shown in FIG. 7, before assembly, the flat plate support frame 3 can be folded toward the flat plate leaning frame 2. To achieve this, the movable frame 31, located in the post-assembly through-hole 512 shown in FIG. 6, is moved through the S-shaped through-hole 51 to the pre-assembly through-hole 511 shown in FIG. 8. This moves the movable frame 31 forward of the flat plate support frame fixing portion 5, allowing the flat plate support frame 3 to be rotated so that it leans against the flat plate leaning frame 2, thereby folding the flat plate support frame 3. Having the S-shaped connecting hole 513 through which the movable frame 31 can move allows the movable frame 31 to slide to change the position of the flat plate support frame 3 before and after assembly, facilitating storage and assembly. Furthermore, since the movable frame 31 can be securely fixed in the pre-assembly through-hole 511, the flat plate support frame 3 can be prevented from swaying even when carried in its compact, pre-assembled state. In this embodiment, the through hole 51 is shown to be S-shaped (approximately S-shaped), but the shape is not limited as long as the movable frame 31 can be supported below the lower end of the flat plate leaning frame 2 after assembly.

[0028] In this embodiment, as shown in FIG. 2 , the post-assembly through-hole 512 is located on a plane parallel to the U-shaped base frame 21 attached to the upper part of the flat plate support frame fixing portion 5. This makes it easier to position the movable frame 31 lower than the lower end of the flat plate leaning frame 2 when the dolly 6 is loaded onto the flat plate carrier 1, making it easier to prevent upward vibration or rattle of the flat plate support frame 3. Furthermore, the pre-assembly through-hole 511 is located forward of a plane parallel to the U-shaped extendable frame 22. This makes it possible to fold the flat plate support frame 3. In this embodiment, the pre-assembly through-hole 511 and the post-assembly through-hole 512 are substantially circular. However, the shape of the pre-assembly through-hole 511 is not limited as long as it is a hole that can fix the flat plate support frame 3 in a folded state, and the shape of the post-assembly through-hole 512 is not limited as long as it is a hole that can fix the flat plate support frame 3 in an open state. As shown in Fig. 8, when the flat plate support frame 3 is folded, the flat plate leaning frame 2 (base frame 21 and extendable frame 22) and the flat plate support frame 3 are tightly attached to the top of the flat plate support frame fixing portion 5. In this embodiment, the width (horizontal width) of the flat plate support frame fixing portion 5 is 95% or more and 105% or less of the combined frame thickness of the flat plate leaning frame 2 and the flat plate support frame 3, so that the storage state can be maintained more stably.

[0029] (fixed frame) 1 to 5, the fixed frame 4 is a portion for fixing the flat plate carrier 1 to the upper surface of the carriage 6, and is attached to the underside of the flat plate leaning frame 2. The fixed frame 4 has a rectangular carriage abutment frame 41 with a rectangular cross section that is attached to the upper surface of the carriage 6, and a substantially rectangular support frame 42 with a rectangular cross section that is fixed to the carriage abutment frame 41 and supports the underside of the flat plate leaning frame 2 from below.

[0030] 10 is a perspective view showing the state in which the bogie abutment frame 41 is folded from the state shown in FIG. 9. First, as shown in FIGS. 1 and 2, one side of the rectangular bogie abutment frame 41 is formed by a connecting frame 413 that connects the two flat plate support frame fixing parts 5 below the through-hole 512 (behind the lower part of the flat plate support frame fixing parts 5) after assembly. The connecting frame 413 is made up of a metal frame with a round cross section that is rotatably attached to the two flat plate support frame fixing parts 5, and an outer peripheral frame that surrounds the metal frame. Therefore, as shown in FIG. 10, the bogie abutment frame 41 can be folded toward the flat plate leaning frame 2 by rotating the connecting frame 413.

[0031] 1 and 2, the rectangular cart abutment frame 41 has two cart abutment frame fixing portions 411 with a U-shaped cross section at both ends of one rear side (the side facing the connecting frame) for sandwiching the top plate 61 of the cart 6. The cart abutment frame fixing portions 411 have a space on the inside of the U-shaped cross section that is approximately the thickness of the top plate 61, so that the side of the top plate 61 can be sandwiched between them to firmly fix the flat plate carrier 1 to the cart 6. Also, as shown in FIGS. 1 and 5, the rectangular cart abutment frame 41 has a support frame fixing portion 412 with a round cross section at a position near the rear side that connects the two side sides and fixes the support frame 42. The distance (shortest distance) between the connecting frame 413 and the support frame fixing portion 412 may be 50% or more and 98% or less, 60% or more and 95% or less, or 70% or more and 90% or less of the length of the side of the rectangular bogie abutment frame 41.

[0032] 1, 2, and 5, the support frame 42 has a rotatable rotating portion 421 that connects two side edges of the base frame 21 near the upper end of the base frame 21, a U-shaped support portion 422 connected to the rotating portion 421, and an engaging portion 423 that is connected to one middle side of the U-shaped support portion 422 (the side facing the rotating portion 421) and that engages with the support frame fixing portion 412. The rotating portion 421 connects the two side edges of the base frame 21 and is composed of a metal frame with a round cross section that is rotatably attached, and an outer peripheral frame that surrounds the metal frame. In this embodiment, the support frame fixing portion 412 is a metal frame with a round cross section, and the engaging portion 423 has a hook structure that can engage with the support frame fixing portion 412 with a round cross section. In this way, in the flat plate carrier 1 of this embodiment, the support frame 42 can support the underside of the flat plate leaning frame 2 from below, preventing rattle of the flat plate leaning frame 2 and improving stability when a flat plate 7 is placed on it. Furthermore, since the flat plate carrier 1 is fixed by the engagement portion 423 of the support frame 42, stability can be further improved.

[0033] When the flat plate carrier 1 is attached to the cart 6, the support frame 42 may be angled at an angle of 70° to 90°, or 75° to 85°, relative to the upper surface of the cart 6 (the upper surface of the top plate 61). Furthermore, when the flat plate carrier 1 is attached to the cart 6, the support frame 42 may be angled at an angle of 10° to 50°, or 20° to 40°, relative to the lower surface of the flat plate leaning frame 2. By having the support frame 42 support the flat plate leaning frame 2 at such an angle, stability when a flat plate 7 is placed on it can be significantly improved.

[0034] 11 is a perspective view showing the state in which the support frame 42 has been folded from the state shown in FIG. 10, i.e., a perspective view showing the state in which the flat plate carrier 1 of the present invention is stored compactly. As shown in FIGS. 9 and 10, the engaging portions 423 of the support frame 42 are detached from the support frame fixing portions 412 of the carriage abutment frame 41, and the two carriage abutment frame fixing portions 411 are detached from the top plate 61 of the carriage 6. After that, the connecting frame 413 is rotated to fold the carriage abutment frame 41 toward the plate leaning frame 2, and finally, as shown in FIG. 11, the rotating portions 421 of the support frame 42 are rotated to fold the support frame 42. This makes the flat plate carrier 1 of the present invention compact and easy to carry.

[0035] (cart) The carriage 6 on which the flat plate carrier 1 of the present invention is mounted is preferably a four-wheeled carriage, as shown in the drawings, but may also be a three-wheeled carriage. When the flat plate carrier 1 of the present invention is mounted on a three-wheeled carriage, the carriage can be easily moved forward and backward, but when it is desired to move the carriage in a direction perpendicular to the forward and backward direction of the carriage, the carriage must be driven in a serpentine manner. Therefore, in consideration of the mobility of the carriage, it is preferable to use a four-wheeled carriage, as shown in Figures 1 to 5.

[0036] (Storage and assembly) The plate carrier 1 of the present invention can be stored compactly and easily assembled without the need to attach or detach each frame, which eliminates the problems of losing track of the attachment positions of each frame or losing a frame, which were previously encountered. A method for compactly storing the flat plate carrier 1 attached to the cart 6 in this embodiment will be described. The state shown in FIGS. 1, 2, and 5 is the state in which the flat plate carrier 1 is attached to the cart 6 and a flat plate 7 can be loaded. From this state, the movable frame 31 (FIGS. 5 and 6) fixed to the post-assembly through-hole 512 of the flat plate support frame fixing portion 5 is moved to the pre-assembly through-hole 511 via the S-shaped connecting hole 513, and then the flat plate support frame 3 is folded toward the flat plate leaning frame 2, and the two leg members 32 are rotated so that they face each other to store it under the flat plate support frame 3 (FIGS. 7 and 8). Next, the length of the extendable frame 22 in the flat plate leaning frame 2 is shortened and the protrusions 212 are inserted into the holes 33 of the flat plate support frame 3, allowing the flat plate leaning frame 2 to be stored (FIG. 9). Next, the engaging portion 423 of the support frame 42 is removed from the support frame fixing portion 412 of the carriage abutment frame 41, and the two carriage abutment frame fixing portions 411 are removed from the top plate 61 of the carriage 6. Then, the connecting frame 413 is rotated to fold the carriage abutment frame 41 toward the flat plate leaning frame 2 (FIG. 10). Finally, the rotating portion 421 of the support frame 42 is rotated to fold the support frame 42 toward the flat plate leaning frame 2 (FIG. 11). Although not shown, the flat plate carrier 1 may have a locking mechanism to prevent each frame from being opened when folded. The flat plate carrier 1 of the present invention is composed of separate members from the carriage and can be stored compactly in a sheet-like manner without removing the frames. Therefore, when plates are not being transported, the flat plate carrier can be removed from the carriage and is easy to transport. Furthermore, it can be easily transported through narrow passages and on scaffolding, and the flat plate carrier 1 can also be placed on the carriage 6 and transported to the construction site. Furthermore, the flat plate carrier 1 of the present invention can be attached to a four-wheeled cart 6, which has the advantage that by mounting it on a four-wheeled cart 6, it can be easily pushed along perpendicular to the direction of travel of the cart 6.

[0037] The method for assembling the flat plate carrier 1 in this embodiment from a folded state is simply the reverse of the above-described method for compact storage. Specifically, if the flat plate carrier 1 is folded into a single sheet as shown in FIG. 11, the locking function is released, and then the support frame fixing portion 421 is rotated to pull the support frame 42 rearward (FIG. 10). Next, the connecting frame 413 is rotated to pull the carriage abutment frame 41 rearward, and the carriage abutment frame fixing portion 411 is attached to the side of the top plate 61 of the carriage 6. Then, the engaging portion 423 of the support frame 42 is engaged with the support frame fixing portion 412 to fix the support frame 42 to the carriage abutment frame 41 (FIG. 9). Next, the extendable frame 22 is extended upward (FIG. 7). Furthermore, the movable frame 31 fixed to the pre-assembly through-hole 511 is moved to the post-assembly through-hole 512 via the S-shaped connecting hole 513, and the flat plate support frame 3 is pulled forward (FIGS. 5 and 6). In this way, the flat plate carrier 1 of the present invention can be easily used by simply assembling the frames.

[0038] Conventional flat plate carriers require the attachment and detachment of each frame, which can lead to problems such as confusion about which frame to attach to which location, or the loss of parts of the frame when removed. In contrast, the flat plate carrier of the present invention does not require the attachment and detachment of each frame, can be easily assembled, and can be stored compactly. Furthermore, while an assembly-friendly configuration can cause problems with upward deflection and rattle, the flat plate carrier of the present invention, despite its easy assembly, can prevent the flat plate support frame from deflecting upward or rattle when a single flat plate is placed on the flat plate leaning frame. Therefore, it can be suitably used as a flat plate carrier that can be attached to a cart. [Explanation of symbols]
