Description

[Technical field]

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

[0002] Due to the nature of their shapes, heavy plate-shaped objects such as interior materials such as alpolic, straw boards, and aluminum office partitions, glass, sashes, plywood, panels, composite panels, and boards cannot usually be loaded onto a standard dolly, and even if they could be loaded onto the dolly, the dolly becomes unstable and difficult to transport, making it dangerous. In addition, the dolly takes up too much space, and the materials and cargo become unstable, making it difficult to proceed with work as expected, and in the worst case scenario, there is a risk that the plate-shaped objects will be hit against walls or pillars, causing damage, or that the dolly or the plate-shaped objects that protrude from the dolly will hit people during transportation. For this reason, heavy plate-shaped objects are sometimes unavoidably transported by hand, which is time-consuming and labor-intensive and inefficient work.

[0003] As an apparatus for efficiently transporting the above-mentioned plate-like heavy 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 respect to the upper surface of the dolly when the flat plate carrier is attached to the dolly, a rectangular flat plate supporting frame that is connected to the lower side of the upper surface of the flat plate leaning frame and is 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 both 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 unclear which frame should be attached to which part, 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 made into a flat plate carrier simply by assembling each frame without the need to attach and remove each frame, 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 provided on 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 sheet-like flat plate is placed on the flat plate leaning frame.

[0008] The present invention has been made in consideration of these circumstances, and its object is to provide an assemblable flat plate transport device that can prevent the flat plate support frame from swaying upward or rattling when a sheet-like 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] That is, the assemblable flat plate carrier of the present invention can be attached to a cart, can transport a flat plate leaning at an angle, and can be assembled. The flat plate carrier of the present invention has a rectangular flat plate leaning frame that forms an angle of 50° to 85° with respect to the upper surface of the cart when the assemblable flat plate carrier is attached to the cart, a rectangular flat plate support frame that is 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 fixing frame that is attached to the lower surface of the flat plate leaning frame and fixes the flat plate carrier to the upper surface of the cart, and a flat plate support frame fixing part that is attached to both ends of the connection part between the flat plate leaning frame and the flat plate support frame, two in total, one on each side, and supports a movable frame that constitutes one side of the flat plate support frame. The flat plate supporting frame fixing portion can pivotally support the movable frame so as to be movable below the lower end of the flat plate leaning frame.

[0011] The collapsible flat plate carrier of the present invention does not require the attachment and detachment of each frame, and can be formed into a flat plate carrier simply by assembling each frame, so there is no risk of forgetting the attachment position of each frame or losing a frame. The flat plate carrier of the present invention is assembled by attaching the flat plate carrier to the dolly using the fixed frame, so that the flat plate leaning frame forms an angle of 50° to 85° with respect to the upper surface of the dolly. In this state, the flat plate can be stably placed on the flat plate carrier by placing the bottom of the flat plate on the flat plate support frame and leaning the surface of the flat plate against the flat plate leaning frame. In addition, by setting the angle between the flat plate leaning frame and the flat plate support frame to 80° to 110°, the surface of the flat plate can easily come into contact with the flat plate leaning frame when the bottom of the flat plate is in contact with the flat plate support frame, so that the flat plate is less likely to wobble when transported on the dolly. Furthermore, since the fixed part of the flat plate support frame is configured to axially support the movable frame so as to be movable below the lower end of the flat plate leaning frame, the end of the movable frame, i.e., the flat plate support frame, can be positioned below the lower end of the flat plate leaning frame after assembly. 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 that the plate carrier can be removed from the cart when plates are not being transported 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 for movably supporting the movable frame. Since the flat plate support frame fixing portion is a member having an S-shaped through hole 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, it is preferable that the flat plate support frame fixing portion has a pre-assembly through hole for fixing the end of the movable frame at a position before the flat plate carrier is assembled, a post-assembly through hole for fixing the end of the movable frame at a position after the flat plate carrier is assembled, and an S-shaped connecting hole connecting the pre-assembly through hole and the post-assembly through hole through which the movable frame can move. By providing a pre-assembly through hole for fixing the movable frame at a position before the flat plate carrier is assembled in this way, it is possible to prevent the flat plate support frame from swinging when the flat plate carrier is carried in a compact state before assembly, and by providing a post-assembly through hole for fixing the end of the movable frame at a position after the flat plate carrier is assembled, it is possible to further prevent the flat plate support frame from swinging upward or rattling even when a flat plate is placed on the flat plate leaning frame after assembly, and therefore the stability of the transported flat plate can be further improved. 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 has a rectangular carriage abutment frame attached to the upper surface of the carriage, and a support frame fixed to the carriage abutment frame and supporting the lower surface of the flat plate leaning frame from below. By having a rectangular carriage abutment frame attached to the upper surface of the carriage in this manner, the flat plate carrier can be more firmly fixed to the carriage. Furthermore, by having a support frame fixed to the carriage abutment frame and supporting the lower surface of the flat plate leaning frame from below, rattling of the flat plate leaning frame can be prevented, and stability when a flat plate is placed on the carriage can be further improved. Effect of the Invention

[0015] The assemblable flat plate carrier of the present invention is excellent in stability of the plate being transported because it can prevent the flat plate support frame from swaying upward or rattling when a sheet-like flat plate is placed on the flat plate leaning frame. Also, it is not necessary to attach or remove each frame, and the flat plate carrier can be made by simply assembling each frame. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 gist of the present invention.

[0018] Fig. 1 is a perspective view of the flat plate carrier 1 of the present invention attached to a dolly 6, as viewed obliquely from the rear, Fig. 5 is a perspective view of the flat plate carrier 1 of the present invention attached to a dolly 6, as viewed obliquely from the front, and Fig. 3 is a perspective view showing a state in which a heavy load, a flat plate 7, is loaded onto 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 dolly 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 part 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 part on 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 end of the base frame 21 and the extension frame 22, are fixed to the upper end of the flat plate support frame fixing part 5. As shown in Fig. 1, 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 in a state in which the flat plate carrier 1 is attached to 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, and the stability of the flat plate 7 during the dolly operation can be improved. In this specification, the upper surface of the flat plate leaning frame 2 refers to the surface facing the flat plate support frame 3, and the lower surface of the flat plate leaning frame 2 refers to the surface facing the fixed frame 4 (the right side in Fig. 2). In addition, in this specification, the lower side refers to the side approaching the dolly 6 when the flat plate carrier 1 is mounted on the dolly 6, and the upper side refers to the side away from the dolly 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 a reference, and the rear side (or rear) refers to the fixed frame 4 side (the right side in Fig. 2) when the flat plate leaning frame 2 is used as a reference.

[0020] As shown in Figs. 1, 2 and 5, the telescopic frame 22 has a metal frame built in each of the metal frames on the two sides, and the upper ends of the two thin metal frames are connected by a single metal frame. The thin metal frame can be pulled out and fixed in the upward position, so that the vertical length of the flat plate leaning frame 2 can be adjusted. If the size of the flat plate 7 to be transported is large, the size of the flat plate leaning frame 2 can be adjusted to a size on which the flat plate 7 can stably lean by adjusting the vertical length of the telescopic frame 22. As shown in Figs. 3 and 4, the vertical length of the flat plate leaning frame 2 is preferably 60% or more of the vertical length of the flat plate 7 to be transported.

[0021] As shown in Fig. 1, Fig. 2 and Fig. 5, the telescopic frame 22 is provided with two flat plate support frame fastening parts 211 at the upper ends of two sides, respectively, to which the flat plate support frame 3 in the folded state before assembly can be fastened (or fixed). Here, Fig. 7 is a perspective view of the flat plate carrier 1 of Fig. 5 in a folded state of the flat plate support frame 3 and the leg member 32, and Fig. 9 is a perspective view from the diagonal rear 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 flat plate support frame fastening parts 211 each have a protrusion 212 at its lower end, and the flat plate support frame 3 described later has a hole 33 at the tip of the metal frame of the two sides (the tip opposite to the flat plate support frame fixing part 5). 7 and 9, with the flat plate support frame 3 folded, the flat plate leaning frame 2 can be stored by 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 can better prevent the flat plate support frame 3 from wobbling when the flat plate carrier 1 is carried, making it easier to carry.

[0022] (Flat plate support frame) As shown in Figs. 1 to 5, the flat plate support frame 3 is provided to support the bottom of a heavy flat plate, and is rectangular. One side of the rectangle is formed by a metallic movable 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 in order to improve the load-bearing capacity of the flat plate support frame 3, a metal frame is further attached that connects the metal plate to the side of the U-shaped metal frame.

[0023] In this embodiment, the flat plate support frame 3 is attached to both ends of the U-shaped flat plate leaning frame 2 at an angle of 90° to the upper surface of the flat plate leaning frame 2 by using flat plate support frame fixing parts 5 described later. As shown in Figures 3 and 4, a heavy flat plate is loaded onto the flat plate support frame 3 with the surface of the 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 between 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 the heavy flat plate 7 is loaded onto the flat plate support frame 3, a gap is unlikely to be generated between the flat plate 7 and the flat plate leaning frame 2, and rattling 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 it is not essential that it be 90°, 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 lower surface of the rectangular flat plate support frame 3. As shown in FIG. 2, 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 lower surface of the leg members 32 (the surface opposite to the flat plate support frame 3) is formed to be in close contact with the surface of the dolly 6. This allows the flat plate support frame 3 to be supported more stably, so that when a heavy object such as a flat plate 7 is loaded onto 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 to face each other and stored on the underside of the flat plate support frame 3. Therefore, with the flat plate carrier 1 fixed to the dolly 6 by the fixing frame 4, it can be easily moved by the dolly 6 even in narrow passages or on scaffolding. Note that, although two leg members 32 are attached in this embodiment, 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, 1 to 4.

[0026] (Flat plate support frame fixing part) In this embodiment, as shown in Fig. 1 to Fig. 5, 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 center of two opposing faces, and the S-shaped through holes 51 movably support a movable frame 31 with a round cross section that constitutes one side of the flat plate support frame 3. In this embodiment, the S-shaped through hole 51 has a pre-assembly through hole 511 for fixing the end of the movable frame 31 at a position before assembling the flat plate carrier 1, a post-assembly through hole 512 for fixing the end of the movable frame 31 at a position after assembling the flat plate carrier, and an S-shaped connection hole 513 for connecting the pre-assembly through hole 511 and the post-assembly through hole 512 and allowing the movable frame 31 to move. The pre-assembly through hole 511 is located at the front part (flat plate support frame 3 side) of the flat plate support frame fixing part 5, and the post-assembly through hole 512 is located at the rear part (fixed frame 4 side), and the lower end of the flat plate leaning frame 2 is attached to the upper part of the post-assembly through hole 512. Since cylindrical thin pieces of a size that cannot be inserted into the S-shaped through hole 51 are formed at both ends of the movable frame 31, the movable frame 31 can be pivotally supported by the S-shaped through hole 51 without coming off. As shown in FIG. 6, after assembly, the movable frame 31 is pivotally supported by the through-hole 512 after assembly, so that the movable frame 31 can be positioned below the lower end of the flat-plate leaning frame 2, i.e., the end of the flat-plate support frame 3 can be positioned below the lower end of the flat-plate leaning frame 2. The "lower side" here means the side that is perpendicular to and close to the top plate 61 when the flat-plate carrier 1 is mounted on the dolly 6. For example, as shown in FIG. 2, the lower side of the lower end of the flat-plate leaning frame 2 means the side that is perpendicular to the top plate 61 from the lower end of the flat-plate leaning frame 2. With this feature, even if a sheet-like flat plate 7 is placed on the flat-plate leaning frame 2, the flat-plate support frame 3 can be prevented from swinging upward or rattling, and the stability of the flat plate 7 being transported can be improved. In addition, since the movable frame 31 is firmly fixed to the through-hole 512 after assembly, the effect of stability becomes more pronounced.

[0027] FIG. 8 is an enlarged view of the flat plate support frame fixing portion of 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 state, the movable frame 31 located at the post-assembly through hole 512 shown in FIG. 6 is moved to the pre-assembly through hole 511 shown in FIG. 8 through the S-shaped through hole 51. Then, the movable frame 31 moves to the front part of the flat plate support frame fixing portion 5, so that the flat plate support frame 3 can be rotated so as to lean against the flat plate leaning frame 2, and the flat plate support frame 3 can be folded. In this way, by having the S-shaped connection hole 513 through which the movable frame 31 can move, the position of the flat plate support frame 3 can be changed by sliding the movable frame 31 before and after assembly, which makes storage and assembly easy. Furthermore, since the movable frame 31 can be firmly fixed to the pre-assembly through hole 511, the flat plate support frame 3 can be prevented from swinging even when it is carried in a compact state before assembly. In this embodiment, the through hole 51 is 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 part 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 mounted on the flat plate carrier 1, making it easier to prevent the flat plate support frame 3 from swinging upward or rattling. In addition, the pre-assembly through hole 511 is located forward of a plane parallel to the U-shaped extensible 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 approximately circular, but 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 post-assembly through hole 512 is a hole that can fix the flat plate support frame 3 in an open state. 8, when the flat plate support frame 3 is folded up, the flat plate leaning frame 2 (base frame 21 and extensible frame 22) and the flat plate support frame 3 are attached in close contact with the upper part of the flat plate support frame fixing part 5. In this embodiment, the width (horizontal width) of the flat plate support frame fixing part 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 stored 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 dolly 6, and is attached to the underside of the flat plate leaning frame 2. The fixed frame 4 has a rectangular dolly abutment frame 41 with a rectangular cross section attached to the upper surface of the dolly 6, and a substantially rectangular support frame 42 with a rectangular cross section that is fixed to the dolly abutment frame 41 and supports the underside of the flat plate leaning frame 2 from below.

[0030] Fig. 10 is a perspective view showing a state in which the carriage abutment frame 41 is folded up from the state shown in Fig. 9. First, as shown in Figs. 1 and 2, one side of the rectangular carriage abutment frame 41 is formed of a connecting frame 413 that connects the two flat plate support frame fixing parts 5 at a position 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 composed 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 carriage abutment frame 41 can be folded up towards 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 parts 411 with a U-shaped cross section for sandwiching the top plate 61 of the cart 6 at both ends of one side on the rear side (one side facing the connecting frame). The cart abutment frame fixing parts 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 flat plate carrier 1 can be firmly fixed to the cart 6 by sandwiching the side of the top plate 61. Also, as shown in FIGS. 1 and 5, the rectangular cart abutment frame 41 has a support frame fixing part 412 with a round cross section at a position close to the rear side, which 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 part 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] As shown in Figs. 1, 2 and 5, the support frame 42 has a pivotable pivot part 421 that connects two sides of the base frame 21 near the upper end of the base frame 21, a U-shaped support part 422 connected to the pivot part 421, and an engagement part 423 that is connected to one side in the middle of the U-shaped support part 422 (one side facing the pivot part 421) and engages with the support frame fixing part 412. The pivot part 421 connects two sides of the base frame 21 and is composed of a metal frame with a round cross section that is attached to be pivotable, and an outer peripheral frame that surrounds the metal frame. In this embodiment, the support frame fixing part 412 is a metal frame with a round cross section, and the engagement part 423 has a hook structure that can engage with the support frame fixing part 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 wobbling of the flat plate leaning frame 2 and improving stability when the flat plate 7 is placed on it. Furthermore, since it is fixed by the engagement portion 423 of the support frame 42, stability can be further improved.

[0033] With the flat plate carrier 1 attached to the cart 6, the support frame 42 may be inclined at an angle of 70° to 90°, or 75° to 85°, relative to the upper surface of the cart 6 (upper surface of the top plate 61). With the flat plate carrier 1 attached to the cart 6, the support frame 42 may be inclined 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 more significantly improved.

[0034] Fig. 11 is a perspective view showing a state in which the support frame 42 is folded up from the state shown in Fig. 10, that is, a perspective view showing a state in which the flat plate carrier 1 of the present invention is stored compactly. As shown in Figs. 9 and 10, the engaging portion 423 of the support frame 42 is removed from the support frame fixing portion 412 of the cart abutting frame 41, and the two cart abutting frame fixing portions 411 are removed from the top plate 61 of the cart 6, and then the connecting frame 413 is rotated to fold the cart abutting frame 41 toward the flat plate leaning frame 2, and finally, as shown in Fig. 11, the rotating portion 421 of the support frame 42 is rotated to fold the support frame 42. This makes the flat plate carrier 1 of the present invention compact and easy to carry.

[0035] (Trolley) The dolly 6 on which the flat plate carrier 1 of the present invention is mounted is preferably a four-wheel type as shown in each drawing, but may be a three-wheel type. When the flat plate carrier 1 of the present invention is mounted on a three-wheel type dolly, the dolly can be easily moved forward and backward, but when it is desired to move the dolly in a direction perpendicular to the forward and backward direction of the dolly, the dolly must be made to snake. Therefore, in consideration of the mobility of the dolly, it is preferable to use a four-wheel type dolly as shown in Figs. 1 to 5.

[0036] (Storage and assembly) The flat plate carrier 1 of the present invention can be stored compactly without attaching or detaching each frame, and can also be assembled easily. Therefore, there is no longer the problem of forgetting where each frame is attached or losing a frame, which was previously the case. A method for compactly storing the flat plate carrier 1 attached to the dolly 6 in this embodiment will be described. The state shown in Figs. 1, 2 and 5 is a state in which the flat plate carrier 1 is attached to the dolly 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 part 5 is moved to the pre-assembly through hole 511 via the S-shaped connection 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 as to face each other and stored on the underside of the flat plate support frame 3 (Figs. 7 and 8). Next, the length of the expandable frame 22 in the flat plate leaning frame 2 is shortened and the protrusion 212 is inserted into the hole 33 of the flat plate support frame 3, so that the flat plate leaning frame 2 can 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 cart abutment frame 41, and the two cart abutment frame fixing portions 411 are removed from the top plate 61 of the cart 6. Then, the connecting frame 413 is rotated to fold the cart 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 can have a lock structure to prevent each frame from being opened when folded. The flat plate carrier 1 of the present invention is composed of a separate member from the cart and can be stored compactly in a sheet-like manner without removing each frame, so that when the flat plate is not being transported, the flat plate carrier can be removed from the cart and is easy to carry. In addition, the flat plate carrier 1 can be easily carried even in narrow passages and scaffolding, and can also be carried to the site by placing it on the cart 6. Furthermore, since the flat plate carrier 1 of the present invention can be attached to a four-wheeled cart 6, there is also the advantage that by mounting it on a four-wheeled cart 6, it can be easily pushed forward perpendicular to the direction of travel of the cart 6.

[0037] The method of assembling the flat plate carrier 1 in this embodiment from a folded state can be performed by performing the reverse operation of the above-mentioned method of compact storage. Specifically, if the flat plate carrier 1 folded into a sheet as shown in FIG. 11 has a locking function, the locking function is released, and then the support frame fixing part 421 is rotated to draw the support frame 42 backward (FIG. 10). Next, the connecting frame 413 is rotated to draw the dolly abutment frame 41 backward, and the dolly abutment frame fixing part 411 is attached to the side part of the top plate 61 of the dolly 6, and then the engagement part 423 of the support frame 42 is engaged with the support frame fixing part 412 to fix the support frame 42 to the dolly abutment frame 41 (FIG. 9). Next, the extension frame 22 is extended upward (FIG. 7), and further, 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 connection hole 513, and the flat plate support frame 3 is drawn 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 individual frames.

[0038] Conventional flat plate carriers require the installation and removal of each frame, which can lead to problems such as not knowing which frame should be installed on which part, or losing parts of the frame when removed. In contrast, the flat plate carrier of the present invention does not require the installation and removal of each frame, can be easily assembled, and can be stored compactly. Furthermore, while an assembly-friendly configuration can cause problems such as upward swing and rattling, the flat plate carrier of the present invention can be easily assembled and prevents the flat plate support frame from swinging upward or rattling when a sheet-like 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]
