Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support stand that can be disassembled and assembled, for example, as a bonfire stand.

When a bonfire or charcoal fire is burned outdoors, a support stand that can be disassembled and assembled is used to support the fuel, and it can be disassembled and stored in a small size for easy carrying. For example, Patent Literature 1 describes an example of a portable pedestal that can be disassembled and assembled. As shown in FIG. 8, the support base described in Patent Document 1 uses a bottom plate by inserting a notch in a flat plate into a notch in another plate and sliding them to connect a plurality of flat plates. Therefore, it is possible to maintain the structure and repeat disassembly and assembly.

JP 2011-75270 A

According to the above technique, since the connection between the flat plates is not fixed during assembly, it is difficult to assemble, and a bottom plate is required to maintain the structure. Also, due to the combination of parts with multiple shapes, it becomes unusable due to partial failure or loss.

The problem to be solved by the present invention is that it is easy to assemble without being easily disassembled only by connecting flat plates. To provide a small and light pedestal which can be disassembled and assembled. Another object of the present invention is to provide a pedestal which is convenient for storage not only for camping and hiking but also when a natural disaster occurs, and which can be used continuously by changing the number of flat plates even if the pedestal is broken or lost.

In order to solve the above problems, the bearing base according to claim 1 of the present invention has a connection side A having an inward notch A at both ends that can be connected to each other on a flat plate, and an outward notch B at both ends. The flat plate has a connection side B having a has the connection side A and the connection side B on the left and right, the lower end is narrower than the upper end, and three or more pieces are connected in a continuous ring to form an inverted cone-shaped concave support recess.

Further, in the bearing base according to claim 1, the space between the notches A facing inward is opened so that the connecting side B can be easily fitted, and the connecting side B connected to the notches A is formed by the notch. It protrudes from B and becomes a leg when constructing the support base and a handle when assembling. Further, according to claim 3 of the present invention, there is provided a support base according to claim 1 or 2, wherein the distance between the cutouts B is greater than the distance between the cutouts A, , the flat plate is always curved when connected, and the notches are in contact with each other without gaps. Further, a support base according to claim 4 of the present invention is the support base according to any one of claims 1 to 3, wherein the notch A is curved to reduce the gap between the notch A and the flat plate connected. An arc is drawn according to the

Further, a support base according to claim 5 of the present invention is the support base according to any one of claims 1 to 4, wherein a plurality of the cutouts B are provided on the flat plate, and the cutouts A are connected to each other. It is possible to change the position.

According to the present invention, it is not disassembled even during assembly, it is easy to assemble because it has a handle so that it can be easily bent at the time of assembly, and it can be assembled only with flat plates of the same shape, so it can be assembled even if part of it breaks down or is lost. A pedestal can be provided. In addition, when disassembled, the flat plate is small and thin compared to the size of the bearing recess, so it is convenient for storage. Since it is possible to adjust fuel consumption and assemble multiple pedestals, it is small, light and convenient to store not only in camping but also in the event of a disaster.

It is a perspective view showing one embodiment of this invention. FIG. 2 is a plan view showing the shape of a flat plate that constitutes FIG. 1; FIG. 3 is a perspective view showing a form when five flat plates of FIG. 2 are connected; FIG. 2 is a perspective view showing an embodiment of a bearing base having a different shape from the bearing base of FIG. 1; FIG. 5 is a plan view showing the shape of a flat plate that constitutes FIG. 4; FIG. 6 is a perspective view showing a form in which the support base shown in FIG. 1 and the support base shown in FIG. 5 are combined; FIG. 6 is a perspective view showing a form in which a top plate is placed by changing the connection method of the flat plates of the support base shown in FIG. 5 ; 1 is a perspective view showing a conventional technique; FIG.

An embodiment of the invention is shown in FIGS. 1-7. The main body of the bearing base is a flat plate having an elastic force, and by connecting three or more flat plates A in FIG. By connecting the sheets, the 6-sheet bearing base A shown in FIG. 1 is obtained. The flat plate A has a trapezoidal shape in which the upper long side and the lower short side of the inverted cone-shaped concave support recess are substantially parallel, and has connection sides A and B connected to other flat plates on the left and right sides. The connecting side A and the connecting side B are connectable to each other, the connecting side A having an inwardly directed notch A at each end, the gap between which is open and arcs to match the curvature of the flat plates to be connected. ing. The connecting side B has outwardly facing notches B at both ends, the distance between the notches B at both ends is greater than the distance between the notches A at both ends, and the distance therebetween protrudes to become the legs of the bearing base. Furthermore, when the connection side A is connected, it becomes a handle that can be held by hand without interfering with the connection side A. - 特許庁In addition, the leg has a ring through-hole for attaching a ring or the like to hold the flat plate together during disassembly.

By connecting six flat plates B shown in FIG. A 6-piece set bearing base B is placed on the ground in a cone-shaped convex shape, and a 6-piece set bearing base A is inserted into the central opening to form a double assembly bearing base shown in FIG. The two-unit assembly support base is more stable, the weight that can be supported is increased, and when used as a bonfire stand, the burning part is separated from the ground surface, so that the influence of combustion on the ground can be reduced. By installing a bottom plate on the bearing projection, it is possible to further reduce the impact on the ground.

The flat plate B has a notch B and a notch B' that can be connected to the notch A, and by changing the connection position, it is possible to change the shape of the support. In addition, it is possible to assemble a deformed polygonal prism by connecting an even number of flat plates by turning them upside down one by one. When six flat plates B are connected upside down one by one, it becomes a deformed hexagonal prism shown in Fig. 7, and the stability and the weight that can be supported are greater than when it is made into an inverted pyramid concave shape, and by placing a top plate on top It can be used as a table or the like.
