In the conventional carrier, there is no problem in carrying a packing case or the like having a substantially rectangular parallelepiped shape, but a large rectangular shape in plan view having a certain thickness such as a tatami mat or the like. It is extremely inconvenient when carrying goods.
When carrying a tatami mat up to now, a large-sized carrier truck of the conventional type is used, and the tatami mat's surface faces upward, and some of them are stacked and placed on the article loading section of the cart, or The front side or the rear side is directed, the side edges in the longitudinal direction thereof are faced down, several pieces are overlapped, and a string or the like is further hung and fixed to the carriage for transportation. This kind of transportation method takes time and effort to hang strings, and when transporting in an apartment house where elevators such as today's high-rise buildings are used, the trolley with the tatami mat etc. There was a problem that it could not be carried inside.

Therefore, in the present invention, a large-sized article having a constant thickness, such as a tatami mat, having a substantially rectangular shape in a plan view can be very conveniently mounted on the article mounting portion and can be mounted on the article mounting portion. It is an object of the present invention to provide a carrier truck that can easily support an article with one touch, and further, even if these articles are left on the carriage, the carrier truck can be carried into an elevator such as a high-rise house. Is intended to be provided. The carriage according to the present invention is
It is suitable for transporting not only the above-mentioned tatami mats but also other various wall plate materials, floor plate materials, and other plate-shaped articles having a constant thickness and having a substantially rectangular shape that is large in plan view. In addition, the article does not necessarily have to be a substantially quadrangular shape in plan view.
As long as the sides have substantially right-angled corners, they can be conveniently carried by the carrier truck according to the present invention, and for example, even plate-shaped articles having a substantially right-angled triangle in plan view can be placed.

[0005]

In order to solve the above-mentioned problems, the first aspect of the present invention is to move an article placing section for placing an article to be conveyed and an article placing section. In the carrier cart composed of a wheel for storing the article and a backrest provided upward from the rear of the article placement section, a side support member for supporting the side of the article to be placed is provided and placed. A plurality of stopper members having a constant width or a constant interval for supporting one side edge of the article, and / or for supporting the side of the article to be placed on the lower end side. The supporting member is provided on the article placing section or is provided over both the article placing section and the backrest section to convey a plate-like article having a constant thickness such as a tatami mat. According to the present invention, an article to be placed such as a tatami mat is leaned in sequence along the side support plate so that one side edge portion (long side portion) in the longitudinal direction thereof abuts on the backrest side. Each stopper member sequentially supports its long side portion, or the lower side of the tatami side (front surface or back surface) is also sequentially supported by the support member. Thus, in the present invention,
By the presence of the side support plate and the support of the stopper member or the support member, articles such as tatami mats can be simply placed and supported in sequence.

A second aspect of the present invention is the same as the first aspect of the present invention, in which each of the constituent members is made foldable and can be folded and stacked on the article placing portion, and further, the lateral support provided on at least one side. The positions of the front and rear wheels on the side of the member are arranged outside the article mounting portion, and the outer periphery thereof is located behind both rear wheels at a position higher than the grounding position of the rear wheels in a normal traveling state. It has auxiliary wheels. In this way, by arranging the positions of the front and rear wheels on the side of the side support plate provided on one side on the outside of the article placing portion, tatami mats that are sequentially placed from the side of the side support plate are provided. Even when the number of articles such as 1 to 3 is small, the stability of the carriage is not impaired. Since auxiliary wheels are added, when there is a step or step on the transport surface, the front of the article placement part is lifted up and the rear wheel is pushed up so that it rides on the step, but at that time By rotating the wheels as they come into contact with the ground, the rear wheels can be smoothly climbed onto the steps. Even if the transportation surface is flat, this auxiliary wheel should be used even when the height of the entrance / exit of the building is low, and the front of the article placement part is lifted and conveyed in an inclined state. Becomes Furthermore, since it is foldable, it can be kept in a compact state when not in use.

The hook portion 32 at the tip end engages with the hole portions 33 formed in the placing surface 2 of the article placing portion 1 at regular intervals. The space between the holes 33 is substantially the same as the lateral width of the stopper 18. The shape of the hook portion 32 is a hook shape, a hook shape, or the like, and the hole portion 33.
Any shape may be used so long as it can be engaged with. Thus, the tatami mats are vertically leaned one by one from the side support plate 20 side by side, and the hook portions 32 are moved to the side support plate while moving the sliding tube 31 toward the front side in the drawing in accordance with the stacking. The front side or the back side of the tatami mat can be supported by sequentially engaging the hole 33 on the front side from the side of 20. The support arm 30 and the stopper 18
In cooperation with the tatami mat, the tatami mat is supported at two locations, the lateral side (front surface or back surface) on the lower end portion side and the long side portion.

A guide 45 is provided on the side support plate 20 side of the article placing section 1 so that when the first article such as a tatami mat is leaned against, the lower end of the article is placed on the article placing section 1. I try not to shift it from the top to the outside. Further, the guides 4 are also provided on the upper end portion of the upright frame 10 on the side where the side support plate 20 is not provided.
7 is provided to prevent articles such as tatami mats placed from falling sideways. Similar to the side support plate 20, the guide 47 is also configured to be rotatable toward the rear plate 15 side and can be folded. Further, the shape of the guide 47 is not so small as shown in the figure, and the guide 47 is formed into a substantially U-shape and its upper end is connected to the upper end of the vertical frame 10, and its lower end is the root of the vertical frame 10. It can also be implemented as a large guide by being connected to the section. However, this guide is not essential and can be implemented without any special provision.

When assembling this carrier, first, the upright frame 10 is erected from the state of being piled up on the article placing portion 1 to a vertical state, and the side supporting plate 20 is piled up on the rear plate 15 first. It opens to the front at a right angle, and the support frame 25 is erected upward so that the connecting arm portion 2 of the side support plate 20

3 and 13 are fixed with thumbscrews 38, and the assembly is completed.

After the completion of the assembly, the tatami mats are sequentially leaned from the side support plate 20 side and stacked vertically so as to be placed vertically. The first sheet is sandwiched between the side support plate 20 and the rightmost stopper 18 in the figure to be supported. When the second tatami mat is brought into contact with the rightmost stopper 18, the stopper 18 falls to the rear plate 15 side due to its own weight of the tatami (at this time, the stopper 18 falls to the rear plate 15 side. Is in a vertical state), and is supported and fixed by the side edge of the adjacent stopper 18 which is not tilted. In the same manner, after leaning several pieces, the support arm 30 is moved until it comes into contact with the front surface or the back surface of the tatami mat, and the hook portion 32 at the tip is provided with the hole portion 3.
By engaging with 3, it is possible to support and fix the front surface or the back surface on the lower end side of the tatami mat.

That is, in this embodiment, the width of the stopper 18 is about 6.0 cm, which is equivalent to the thickness of the tatami mat, and the space between the hole portions 33 provided in the article placing section 1 is also tatami mat. And the thickness of. Therefore, the lateral width of the stopper 18 and the interval between the holes 33 can be appropriately set and determined so as to match the thickness of the article to be placed. The stopper 18 is always urged in the outward direction on the side opposite to the rear plate 15 by a spring. When the long side of the tatami mat comes into contact with the stopper 18, the stopper 18 collapses toward the rear plate 15 due to its weight, and the tatami mat falls next to it. It will be supported by the side edges of the stopper 18 which are not present.

Behind the rear wheels 5, 6 is an auxiliary wheel 4
0 and 40 are provided. The auxiliary wheel 40 has an outer diameter smaller than the outer diameter of the rear wheels 5 and 6, and in the case of normal traveling in which all of the front wheels 7 and 8 and the rear wheels 5 and 6 travel while being grounded. It is not grounded on the transport surface. However, when there is a step or a step on the ground, in order to get over this step, the front of the article placing section 1 is lifted and the rear wheels 5, 6 are allowed to ride on this step. However, at this time, the auxiliary wheels 40, 40 can be grounded, and the rear wheels 5, 6 can be assisted so that the rear wheels 5, 6 can smoothly ride on the step. Also,
Even if the conveyance surface is flat, if the height of the entrance / exit of the building is low, in the same manner, the front of the article placement unit 1 is lifted to make it diagonal, and the height of the trolley and the load is increased. This auxiliary wheel is also effective and can be used when lowering and passing through the doorway. The auxiliary wheel 40 need not necessarily have an outer diameter smaller than the outer diameters of the rear wheels 5 and 6, and can be implemented.
The outer periphery of the auxiliary wheel 40 may be located at a position higher than the ground contact position of No. 6. Therefore, the outer diameter of the auxiliary wheel is
It may be the same as or larger than the rear wheels 5, 6.

FIG. 2 is a perspective explanatory view showing a state in which the long side portion of the tatami is supported by the stopper 18 which is the stopper member in the above-mentioned embodiment, and the state before (A) supports the tatami. (B) shows a state in which about three tatami mats are supported. The tatami mat is vertically mounted so that the long side of the tatami mat is in contact with the rear plate 15, and is placed on the carriage. The stopper members that support the long sides of the tatami mat are a plurality of stopper members having a constant width adapted to the thickness of the article to be supported or a plurality of stopper members having a constant interval, and can be tilted up and down. Alternatively, it may be configured so as to be capable of appearing and retracting, and by other means similar to this, so as to be able to sequentially support the side of one side edge portion of the articles that are sequentially leaned against.
For example, the stopper 18 is pivotally supported by the support rod 35, is rotatable, is attached to the rear plate 15 at a certain angle, and is biased by the spring 36 in the clockwise direction about the support rod 35. . Therefore, when the tatami mat is leaned against, the stopper 18 is rotated counterclockwise in the direction of the arrow in the figure, and when the tatami mat is removed, the stopper 18 returns to its original position.
In order to attach the stopper 18 to the rear plate 15 at a certain angle, for example, the end portion of the root portion of the stopper 18 may be appropriately brought into contact with the rear plate 15.

As a result, as shown in FIG. 2B, when the tatami mat is leaned against, the stopper 18 is appropriately tilted toward the rear face plate 15 (that is, the stopper 18 is in a vertical state), and the adjacent stopper is not tilted. The side edges of 18 support the long sides of the tatami. In this embodiment, a space is provided between the stopper 18 closest to the side support plate 20 and the side support plate 20 so that one tatami mat can be inserted therein. As a result, the first one is
The side support plate 20 and the side edges of the stopper 18 on the side closest to the side support plate 20 are fitted into the space and support the tatami mat. The tatami mat from the second sheet is brought into contact with the stopper 18, and the stopper 18 is leaned down to lean against it.
The side edge of the stopper 18 that is not collapsed next to it supports the long side of the tatami. By repeating this process, the long side of the tatami mat is sequentially supported.

The tatami mat 50 is provided between the side support plate 20 and the stopper 18 on the rightmost side in the figure. The long side portion is fitted and the long side portion is supported by the side edge of the stopper 18. On the other hand, the support arm 30 is slid toward the side support plate 20 so that the hook portion 32 at the tip end thereof is engaged with the hole portion 33 on the farthest side in the drawing, and the lower end side of the tatami mat side. It can support either the front or back side. The second and subsequent tatami mats are
The hook 32 of the support arm 30 is disengaged, the support arm 30 is appropriately moved to the front side, the long side of the tatami is brought into contact with the next stopper 18, and is supported by the side edge of the adjacent stopper 18. Next, the support arm 30 is brought into contact with the front surface or the back surface of the lower end of the tatami mat, and the hook portion 32 at the tip is engaged with and supported by the hole portion 33 on the front side. In the same manner, tatami mats can be sequentially supported and fixed.

FIG. 4 is a perspective explanatory view showing a state in which a part of the carriage according to the present invention is folded, and FIG. 5 is a perspective explanatory view showing a state in which it is completely folded. First, the legs 13, 13 of the extension frame 12 are housed inside the upright frame 10 by loosening the thumbscrews 38. The support frame 25 and the connecting arm portion 21 of the side support plate 20 are separated. The two are coupled by engaging the two protrusions provided on one side with the two hole portions provided on the other side. After separating the two, the side support plate 20 is folded toward the rear plate 15. On the other hand, the support frame 25 is superposed on the side frame 3.
