JP 2001-90364 A JP 2008-148990 A

  According to the former of the prior art, the frame of the plate material is not stable even when installed on a flat ground surface, etc. There was a problem that there was no denying the risk of unexpected injuries. When the latter is used, the frame formed by connecting the arc-shaped block bodies is excellent in stability and there is no risk of inadvertent falling, but the size of the pool is fixed depending on the size of the block body In addition, there is a problem that the shape of each block body is complicated and the manufacturing cost tends to be excessive.

  Therefore, in view of the problems of the prior art, the object of the present invention is to form a frame by connecting one type of block having the same shape and the same size as a rectangular parallelepiped, so that the manufacturing cost does not become excessive. It is to provide an assembly pool excellent in practicality.

  In order to achieve this object, the structure of the present invention comprises a frame that forms a recess inside, and a waterproof member that is detachably combined with the frame and waterproofs the recess. The frame has a basic shape. The gist is that the rectangular parallelepiped blocks having the same shape and the same size are connected so as to be disassembled. However, the rectangular parallelepiped here includes a cube, and the basic shape refers to a basic overall shape including an upper surface, a lower surface, and four side surfaces.

  The block body is formed with a notch at each corner in the vertical direction, and the notch is provided with a horizontal connecting piece, and the connecting piece has a position corresponding to the vertical angle of the block body. A pin hole for the connecting pin as the center can be formed, and the notch can be formed so that a part of the connecting piece of another adjacent block body can be accommodated.

  In addition, within the half of the height of the block body, the connecting pieces are arranged in the same height position for each pair of each diagonal direction on the upper surface of the block body, and the height positions of each pair in different diagonal directions May be arranged differently than the thickness of the connecting piece.

  Furthermore, an engaging portion that supports the head of the connecting pin that is inserted into the pin hole may be provided on the upper and lower portions of the notch, and a tab for insertion / removal is formed on the head. Alternatively, the frame body may be provided with a cover material that covers the connecting portion in the vertical direction of the block body exposed to the outside.

  When the configuration of this device is used, the frame body is configured by connecting block bodies having a basic shape of a rectangular parallelepiped, so that it has excellent stability at the time of installation and uses a plurality of block bodies of the same shape and size. Accordingly, a pool of any size can be easily realized while appropriately suppressing the manufacturing cost, and disassembly and assembly are simple, and practicality can be improved. The overall shape of the frame can be made into an arbitrary shape and size in which vertical and horizontal straight lines such as a convex shape, a concave shape, and a cross shape are combined at right angles, in addition to a rectangle and a square. The waterproof member is only required to be combined with the frame and waterproof the concave portion of the frame to eliminate water leakage, and may be an integrally molded product that conforms to the shape of the concave portion and covers at least the inner surface and the bottom surface of the concave portion. A thin foldable sheet material may be used.

  The block body is formed by projecting horizontal connection pieces in the notches at the respective corners in the vertical direction so that the two side by side are brought into close contact with each other and the pin holes of the respective connection pieces are aligned with each other via a common connection pin. Can be connected. Therefore, by repeating the same procedure, a frame body can be configured by connecting an arbitrary number of block bodies in the front-rear and left-right directions. In addition, since the pin hole of each connecting piece has a center at a position corresponding to an angle in the vertical direction of each block body, that is, a position corresponding to an intersection line of two adjacent side surfaces of the block body, the block bodies are brought into close contact with each other. Can be linked. Moreover, the notch provided in the corner | angular part of each block body accommodates a part of connection piece of another adjacent block body, and enables it to arrange | position each block body closely. However, other adjacent block bodies may include those connected adjacently in the diagonal direction without bringing the side surfaces into close contact with each other.

  By arranging the connecting pieces within half the height of the block body, the block bodies can be turned upside down and combined, and a maximum of four block bodies are arranged and connected around a single connection pin. be able to. It should be noted that the connecting pieces have the same height position for each pair of diagonal directions on the upper surface, and the different height positions for each pair of different diagonal directions, so that the connecting pieces of adjacent block bodies can be moved up and down correctly. Can be overlapped.

  The engaging portion formed in each notch supports the head portion of the connecting pin that connects the block body through the pin hole of the connecting piece, positions the connecting pin, and regulates the insertion depth. The engaging portion may be a horizontal engaging rib, or one or two or more engaging protrusions. Further, the connecting pin can be inserted and removed by picking the head with fingers, and the frame can be disassembled and assembled without using a special tool or the like.

  The cover member attached to the frame body can improve the appearance and improve the safety by covering the connecting portion in the vertical direction of the block body exposed to the outside.

  Hereinafter, embodiments of the invention will be described with reference to the drawings.

  The assembly pool includes a frame 10 and a waterproof member 20 (FIG. 1). In addition, in order to protect the waterproof member 20 combined with the frame 10, the cushioning sheet material 31 is attached.

  The frame 10 is formed in a rectangular frame shape having a recess S inside. The frame body 10 is configured by vertically and horizontally connecting block bodies 11, 11... Having a rectangular parallelepiped shape and the same size. In the illustrated frame body 10, all four sides are each composed of upper and lower two-stage block bodies 11, 11..., And two opposite sides are each composed of two rows of block bodies 11, 11. One of the two sides of the block bodies 11, 11... Is provided with a step formed by the one-stage block bodies 11, 11..

  The waterproof member 20 is an integral molded product that fits the frame body 10. The waterproof member 20 is formed by integrally molding a water storage portion 21 that fits into the recess S of the frame body 10 and flange portions 22 that are attached to the entire periphery of the upper end edge of the water storage portion 21. The waterproof member 20 can be used as a pool by fitting the water storage portion 21 into the recess S and allowing the flange portions 22, 22. In the recess S, a cushioning sheet material 31 can be laid to support and protect the bottom surface of the waterproof member 20.

  Each block body 11 is formed with a notch 11a at each corner in the vertical direction of the rectangular parallelepiped, and a horizontal connecting piece 11b is projected in the middle of each notch 11a (FIGS. 2 and 3). 3A and 3B are a top view and a cross-sectional view corresponding to the line AA in FIG. 3A, respectively.

  Each connecting piece 11b is formed in a disk shape and has a pin hole 11c. The pin hole 11c is a circular hole having a center at a position corresponding to the line of intersection of two adjacent side surfaces of the block body 11, that is, a position corresponding to a vertical angle of the block body 11, and the outer shape of the connecting piece 11b is a pin It is coaxial with the hole 11c. Further, the notch 11a is formed in a cross-sectional fan shape corresponding to 1/4 of the connecting piece 11b, and the connecting piece 11b is formed so as to join 1/4 of the outer periphery to the notch 11a. However, the outer shape of each connecting piece 11b may be a polygon other than a circle, and the cross-sectional shape of the notch 11a may be adapted to the outer shape of the connecting piece 11b.

  The connecting pieces 11, 11... Are arranged within half the height of the block body 11. That is, in FIGS. 2 and 3, the connecting pieces 11, 11... Are arranged in the upper half of the block body 11. Each pair of connecting pieces 11, 11 in the diagonal direction on the upper surface of the block body 11 is arranged at the same height position, and different diagonal connecting pieces 11, 11. They are arranged at different height positions corresponding to the thickness of the connecting piece 11. That is, in FIGS. 2 and 3, the lower surface of the low-position side connection pieces 11, 11 is at a height position corresponding to ½ of the height of the block body 11. The lower surface is at a height position that coincides with the upper surfaces of the connecting pieces 11 on the lower position side. However, the lower surface of each connecting piece 11 on the low position side may be higher than the height position corresponding to ½ of the height of the block body 11, and each connecting piece 11 on the high position side and the low position side, It is assumed that a gap may be formed between 11. Therefore, it is sufficient if the height positions of the connecting pieces 11 and 11 on the high position side and the low position side are different from each other more than the thickness of each connecting piece 11.

  On the other hand, an engaging portion 11d in the form of a horizontal engaging rib is formed at the upper and lower portions of each notch 11a.

  The block body 11 can be integrally formed in a hollow shape or a solid shape using, for example, a hard plastic material or a foamed plastic material. In addition, you may form the block body 11 with a reinforcing material as needed. The block body 11 has a so-called two-fold symmetry, which matches the original shape when the block body 11 is rotated by half around the central axis LC in the vertical direction. Moreover, the block body 11 can substantially replace the height positions of the connecting pieces 11, 11... By making a quarter turn around the central axis LC.

  The two block bodies 11 and 11 are arranged in close contact with each other (FIG. 4), so that one high-position connection piece 11b and the other low-position connection piece 11b are vertically aligned at the same position. Can be overlapped. Therefore, if the common connecting pin 12 is inserted into the pin holes 11c and 11c of the connecting pieces 11b and 11b that are vertically overlapped, the block bodies 11 and 11 can be connected in a dismountable manner. However, the connecting pin 12 is positioned by supporting the flange-shaped head portion 12a at the upper end on the engaging portions 11d and 11d of the block bodies 11 and 11, and at this time, the head portion 12a is connected to each engaging portion 11d. The lower end of the main body portion 12b below the head portion 12a hangs down to the lower surfaces of the block bodies 11 and 11, respectively. Moreover, 1/4 of the other connection piece 11b is accommodated in one notch 11a of the block bodies 11 and 11.

  An upward knob 12c is formed on the head 12a of the connecting pin 12 (FIG. 5). The knob 12c is supported at the same height as the upper surface of the head 12a through a small-diameter support 12e at the center of a circular recess 12d formed on the upper surface of the head 12a. The connecting pin 12 can be inserted into and removed from the pin holes 11c and 11c of the connecting pieces 11b and 11b through the knob 12c. However, FIGS. 5A and 5B are a top view and a partially broken front view of the connecting pin 12, respectively.

  The cover member 32 is formed in a semicircular cross section having the same length as the height of each block body 11. A pair of engaging claws 32a and 32a are formed on the upper and lower portions of the inner surface of the cover member 32 so as to protrude horizontally. Therefore, the cover member 32 elastically fits the pair of upper and lower engaging claws 32a, 32a,... To the upper and lower portions of the main body 12b of the connecting pin 12 connecting the block bodies 11, 11. Thus, all of the connecting pieces 11b and 11b, the notches 11a and 11a, and the connecting pin 12 of the block bodies 11 and 11 can be detachably hidden.

  Note that the cover member 32 causes the upper engaging claws 32a and 32a to enter the gap between the upper engaging portions 11d and 11d of the block bodies 11 and 11 and the high-position connecting piece 11b to engage the lower portion. By causing the claws 32a and 32a to enter immediately above the lower engaging portions 11d and 11d, the block bodies 11 and 11 and the connecting pin 12 can be restrained so as not to move relative to each other. However, the vertical dimension h of the engaging claws 32a, 32a is adapted to the gap between the upper engaging portions 11d, 11d and the high-position connecting piece 11b.
