Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat plate carrier capable of easily carrying a plate-shaped heavy object, and more particularly, to a flat plate carrier capable of being attached to a truck and capable of easily carrying a plate-shaped heavy object while attached to the truck. .

Interior materials such as Alpolic, straw board materials, office aluminum partitions, glass, sashes, plywood, panels, concrete panels, boards, and other plate-shaped heavy objects are usually transported by general carts due to their shape characteristics. It cannot be loaded, and even if it can be loaded, the cart becomes unstable and difficult to carry, which is dangerous. In addition, the trolley takes up too much space and the materials and cargo become unstable, making it difficult to proceed with the work as desired. There is also the risk of damage, and the danger of hitting people with a cart or a plate-shaped object protruding from the cart during transportation. For this reason, it is unavoidable to carry a heavy plate-shaped object by hand, which is an inefficient work that takes time and labor.

As a truck for efficiently transporting the plate-shaped heavy object, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2020-050290) discloses a truck for transporting panel materials. The carriage for panel material disclosed in Patent Document 1 includes one wheel provided at the lower part in front of the vehicle body and a frame supported by the wheel. The panel material can be placed across the pair of upper frame side parts toward the side, one corner of the panel material faces upward, and a diagonal corner of the one corner The panel member can be placed so that the portion faces downward between the upper frame front portion and the connecting portion, and the side surface of the panel material abuts against the upper frame front portion and the connecting portion.

By using the panel material carrier disclosed in Patent Document 1, it is possible to safely and efficiently carry a plate-shaped heavy object, so that manual work hours can be reduced.

JP 2020-050290 A

However, the drawbacks of the panel material carrier disclosed in Patent Document 1 are that the carrier becomes unstable while it is being moved because it has only one wheel, and that it is difficult to fix the panel material to the carrier. The work is cumbersome, the loading of panels that are more than twice the size of the carriage makes it unstable, and the carriage cannot be folded, so the work when carrying the carriage is cumbersome. mentioned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a flat carrier that can be easily carried even in narrow passages or scaffolds. An object of the present invention is to provide a flat plate carrier capable of stably carrying a flat panel material.

In order to solve the above-described problems, the present inventors have completed the present invention shown below by earnestly studying the configuration of a flat plate carrier attached to a cart. That is, the flat plate carrier of the present invention can be attached to a carriage, and can be carried by leaning the flat plate obliquely. The configuration of the flat plate carrier of the present invention includes, in a state in which the flat plate carrier is attached to the carriage, a rectangular flat plate leaning frame forming an angle of 50° or more and 85° or less with respect to the upper surface of the carriage; A rectangular flat plate support frame connected to the lower side of the upper surface of the leaning frame and fixed at an angle of 80° to 100° with respect to the upper surface of the flat plate leaning frame, and both front and rear ends of the lower surface of the flat plate leaning frame and a pair of fixed frames attached to the carriage to fix the flat carrier to the upper surface of the carriage.

By attaching the flat carrier to the carriage using a pair of fixed frames, the flat plate leaning frame forms an angle of 50° or more and 85° or less with respect to the upper surface of the carriage. In this state, 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, the flat plate can be stably placed on the flat plate carrier. By setting the angle formed by the flat plate leaning frame and the flat plate support frame to 80° to 100°, the surface of the flat plate is easily brought into contact with the flat plate leaning frame while the bottom of the flat plate is in contact with the flat plate support frame. Therefore, the flat plate is less likely to wobble when it is transported on a trolley. Moreover, since the flat plate carrier of the present invention is composed of a separate member from the carriage, the flat plate carrier can be removed from the carriage when the flat plate is not being carried. There is an advantage that it is easier to carry compared to the case of the configuration with

In the above configuration, it is preferable that each of the pair of fixed frames is rotatably attached to the sides of the lower surface of the flat plate leaning frame. Since the pair of fixed frames are rotatably attached to the side edges of the lower surface of the flat plate lean frame in this way, after the flat plate carrier is removed from the carriage, the pair of fixed frames are turned toward the flat plate lean frame. By rotating the flat plate carrier, the flat carrier can be stored compactly, making it easier to carry.

In the above configuration, the fixed frame, in a state of being attached to the carriage, connects the legs extending perpendicularly to the upper surface of the carriage, the legs and the side edges of the lower surface of the flat plate leaning frame, and and a supporting portion attached to the side edge of the lower surface of the flat plate leaning frame, and fixed portions are preferably provided at the lower ends of the leg portions so as to vertically sandwich the upper surface of the carriage. By supporting the lower surface of the flat plate leaning frame from below with the legs and the support portions in this manner, the flat plate leaning frame can be fixed. In addition, since the fixed frame has a fixing portion that vertically sandwiches the top surface of the carriage, the flat plate carrier can be firmly fixed to the carriage, so that the flat plate can be transported stably. can be further improved.

In the above configuration, it is preferable that the flat plate supporting frame is attached to the lower side of the upper surface of the flat plate leaning frame so as to be rotatable within a maximum range of 90° with respect to the upper surface of the flat plate leaning frame. Since the flat plate support frame is rotatably attached to the lower side of the upper surface of the flat plate leaning frame, the flat plate supporting frame can be rotated to the upper surface of the flat plate leaning frame after the flat plate carrier is removed from the carriage. By doing so, the flat plate carrying tool can be stored compactly, making it easier to carry. Moreover, by setting the angle between the flat plate lean frame and the flat plate support frame to a maximum of 90°, the surface of the flat plate contacts the flat plate lean frame while the bottom of the flat plate is in contact with the flat plate support frame. A flat plate is less likely to rattle when being transported.

In the above configuration, two or more supporting portions are provided as members that connect the leg portions and the side edges of the lower surface of the flat plate leaning frame, and are parallel to the upper surface of the carriage when attached to the carriage. It is preferable that By providing a plurality of support portions parallel to the upper surface of the carriage in this way, members other than the flat plate can be placed on the support portions and transported together with the flat plate. When transporting heavy objects made of flat plates, it is rare to transport only flat plates, and it is common to transport rectangular timbers and bars together with flat plates. can improve work efficiency. Moreover, by arranging a member other than the flat plate on the supporting portion, the weight of the whole truck can be increased, so that the stability of the truck can be further enhanced.

FIG. 7 is a perspective view showing a state in which a flat plate heavy object is mounted, and FIG. 7 is a perspective view showing a state in which other members such as rectangular timbers are mounted on the flat plate carrier of FIG. 2, 4, 6 and 8 are front views of FIGS. 1, 3, 5 and 7, respectively. A flat plate carrier 10 of the present invention is used by being attached to a carriage 20, and is composed of a flat plate leaning frame 11, a flat plate support frame 12, and a pair of fixed frames 13. As shown in FIG. Hereinafter, the front side of the paper surface of FIG. 1 is defined as the front side, and the back side of the paper surface of FIG. 1 is defined as the rear side.

(flat plate leaning frame)
As shown in FIG. 1, the flat plate leaning frame 11 is a portion on which the flat plate 30 rests when the heavy object of the flat plate 30 is mounted, and is formed in a rectangular shape by combining four metal frames. As shown in FIG. 3, the flat plate leaning frame 11 is mounted on the truck 20 so as to form an angle of 50° or more and 85° or less with respect to the top plate 21 of the truck 20. fixed at 20. Since the flat plate leaning frame 11 is fixed to the carriage 20 at such an angle, the flat plate 30 can be mounted so as to lean against the flat plate leaning frame 11 as shown in FIG. , the stability of the flat plate 30 can be improved. Even if the angle of the flat plate leaning frame 11 with respect to the top plate of the carriage 20 is less than 50° or exceeds 85°, the stability of the flat plate is remarkably lowered, which is not preferable.

The flat plate leaning frame 11 incorporates thin metal frames on two sides of the four metal frames. Since the slightly thin metal frame can be fixed in a state of being drawn upward, the vertical length of the flat plate leaning frame 11 can be adjusted. As a result, for example, when the size of the flat plate 30 to be transported is large, by adjusting the length of the flat plate leaning frame 11 in the vertical direction, the flat plate leaning frame 11 can be adjusted to a size on which the flat plate 30 can stably lean. size can be adjusted. As shown in FIGS. 5 and 6, from the viewpoint of stability during transportation, the vertical length of the flat plate leaning frame 11 should be 60% or more of the vertical length of the flat plate 30 to be transported. preferable.

(Flat support frame)
The flat plate support frame 12 is provided to support the bottom of a flat plate heavy object, and is formed into a rectangular shape by combining four metal frames. In this embodiment, in order to improve the load resistance of the flat plate support frame 12, frame members are further attached to reinforce the four metal frames. In this embodiment, the flat plate supporting frame 12 is attached to the lower side of the upper surface of the flat plate leaning frame 11 using a hinge so as to be rotatable with respect to the upper surface of the flat plate leaning frame 11 within a maximum range of 90°.

As shown in FIGS. 5 and 6, a flat plate heavy object is mounted on the flat plate supporting frame 12 with the surface of the flat plate 30 leaning against the flat plate leaning frame 11 . As shown in FIGS. 2 and 4, the surface of the flat plate leaning frame 11 and the surface of the flat plate support frame 12 are assembled so that the angle between them is 90° at the maximum. When mounted on the flat plate support frame 12, a gap is less likely to occur between the flat plate 30 and the flat plate leaning frame 11, and rattling during operation of the carriage 20 can be prevented. In this embodiment, the case where the surface of the flat plate leaning frame 11 and the surface of the flat plate support frame 12 form an angle of 90° (that is, the case where they are orthogonal) has been described, but the angle of 90° is not essential. , the surface of the flat plate support frame 12 with respect to the upper surface of the flat plate leaning frame 11 may be fixed so as to form an angle of 80° to 100°. Even if it is less than 80° or more than 100°, the stability of the flat plate during transportation is lowered, which is not preferable.

(fixed frame)
A pair of fixed frames 13 are parts for fixing the flat plate carrier 10 to the upper surface of the carriage 20, and are attached to the lower surface of the flat plate leaning frame 11 (the surface opposite to the side to which the flat plate support frame 12 is attached). It is rotatably attached to the front and rear sides. The fixed frame 13 is attached to the carriage 20 and connects the legs 131 extending perpendicularly to the upper surface of the carriage 20 and the sides of the lower surface of the flat plate leaning frame 11 to the legs 131 and the flat plate leaning frames. A support portion 133 is attached to the side edge of the lower surface of the carriage 11 , and a fixing portion 132 is provided at the lower end of the leg portion 131 to vertically sandwich the top plate 21 of the carriage 20 .

As shown in FIGS. 4 and 6 , the legs 131 of the pair of fixed frames 13 are in contact with the top plate 21 of the carriage 20 , and the lower ends of the flat plate leaning frames 11 of the flat plate carrier 10 are attached to the top plate of the carriage 20 . 21, and these abutments combine to firmly fix the flat plate carrier 10 on the carriage 20. As shown in FIG. Further, since the leg portion 131 extends perpendicularly to the upper surface of the carriage 20, the leg portion 131 firmly supports the lower surface of the flat plate leaning frame 11 even when the flat plate 30 is stacked on the flat plate leaning frame 11.例文帳に追加be able to. Moreover, since the fixing portion 132 is provided at the lower end of the leg portion 131 so as to sandwich the top plate 21 of the carriage 20, the fixing frame 13 can be fixed by sandwiching the fixing portion 132 between the top plate 21 of the carriage 20. It is possible to further increase the strength.

Here, as shown in FIG. 2 , the fixing portion 132 includes a projection 134 attached perpendicularly to the leg portion 131 at the tip of the leg portion 131 and a projection 134 separated from the projection 134 by about the thickness of the top plate 21 . It has a contact portion 135 that is vertically attached to the leg portion 131 and contacts the upper surface of the top plate 21 , similarly to the projection 134 . The fixed frame 13 is fixed to the top plate 21 by sandwiching the top plate 21 of the carriage 20 between the contact portion 135 and the projection 134 .

In this embodiment, as shown in FIGS. 2, 4, 6, and 8, two support portions 133 are provided as members that connect the leg portions 131 and the sides of the lower surface of the flat plate leaning frame 11. and parallel to the upper surface of the carriage 20 when attached to the carriage 20. - 特許庁By providing the support portion 133 in this way, it becomes possible to load the transported object on the upper side of the support portion 133 as well. When transporting a heavy flat plate 30, it is rare to transport only the flat plate 30, and it is common to transport the rectangular timber 31 and the bar 32 together with the flat plate 30. As shown, by providing two support portions 133, it is possible to transport the square material 31 and the bar material 32 at the same time as the flat plate 30, so that the work efficiency of transportation can be further improved. Moreover, since the weight of the whole truck can be increased by arranging the objects to be conveyed other than the heavy object of the flat plate 30 (such as the square timber 31 and the bar 32 in FIGS. 7 and 8) on the support portion 133, the truck 20 It is possible to further improve the stability of

In this embodiment, the case where two support portions 133 are provided to connect the leg portion 131 and the side edge of the lower surface of the flat plate leaning frame 11 is described as an example, but the number of the support portions 133 is two. The supporting portions 133 are not limited to books, and three or more supporting portions 133 may be provided. As the number of support portions 133 increases, the supporting strength of the flat plate leaning frame 11 can be improved, and the types of objects that can be transported above the support portions 133 can be increased. However, if the number of support portions 133 is excessively increased, it becomes difficult to transport a large object other than a flat plate, so the number of support portions 133 should be appropriately set according to the application.

Therefore, considering the mobility of the truck, it is preferable to use a four-wheeled truck as shown in FIGS.

(Method for storing flat plate carrier)
A method for storing the flat carrier according to the present invention will be described with reference to FIGS. 9 to 11. FIG. 9 is a front view of the flat plate support frame in FIG. 4 in a folded state, FIG. 10 is a view of the fixed frame in FIG. 4 in a folded state, and FIG. 11 is a flat plate leaning frame in FIG. is a diagram showing a state after contracting in the vertical direction. When the flat plate support frame 12 is attached to the upper surface of the flat plate leaning frame 11 so as to be rotatable within a maximum range of 90°, when the flat plate 30 is not being transported, the flat plate supporting frame 12 is placed on the flat plate leaning frame 11 side. By folding (FIG. 9), it is possible to easily move on a carriage even in a narrow passage or scaffold, and when the flat plate carrier 10 is detached from the carriage 20, the flat plate carrier 10 can be stored compactly.

Furthermore, the pair of fixed frames 13 are rotatably attached to the side edges of the lower surface of the flat plate leaning frame 11, so that when the flat plate 30 is not being carried, the pair of fixed frames 13 are positioned as shown in FIG. By folding the fixed frame 13 toward the flat plate leaning frame 11 side, the flat plate carrying tool 10 can be stored in a leaf shape, and can be easily carried even in a narrow passage or scaffolding.

The flat carrier 10 of the present invention, as shown in FIG. 11, has a pair of flat support frames 12 attached to the upper surface of the flat plate leaning frame 11 which are folded and further attached to the lower surface of the flat leaning frame 11. By folding the fixing frame 13, it is possible to store even a single sheet as shown in FIG. As a result, when carrying the flat-plate carrier 10 of the present invention to the site, the flat-plate carrier 10 of the present invention is placed on the cart 20 in a folded state and transported to the site, and when the flat-plate carrier 10 arrives at the site, the flat-plate carrier 10 is attached to the cart 20. You can start transporting flat plates anywhere.

When the flat plate carrier is of the three-wheel type, it is easy to push forward in the direction of movement of the carrier, but it is difficult to move it in the direction perpendicular to the direction of movement of the carrier. There is a need to. On the other hand, the flat carrier of the present invention can be attached to a four-wheeled truck, so it has the advantage that it can be easily pushed in a direction perpendicular to the traveling direction of the truck by mounting it on the four-wheeled truck.

Conventional flat plate transport trucks are difficult to store compactly because the flat plate loading part is integrated with the truck. It was limited to one use only. On the other hand, since the flat plate carrier 10 of the present invention is provided as a separate member from the carriage, it can be carried in a narrow place and can be easily assembled to the carriage on site. The flat plate 30 can be transported even in a limited place. When the work of transporting the flat plate is completed, the flat plate carrier 10 can be removed, folded and stored, and the cart can be used for another purpose as it is, which is convenient.
