Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to blocks for buildings or furniture.

(Prior Art) As a building block, a hollow rectangular parallelepiped block made of glass is known. These building blocks were used to construct side walls for lighting by connecting a large number of them with the front or back sides as walls. Mortar was used to hold the construction blocks in place. That is, a large number of blocks were stacked one on top of the other, and mortar was filled between the blocks to secure them.

However, blocks made of glass are heavy and therefore difficult to handle. On top of that, mortar must be used to fix the blocks, so
The drawback was that it was not easy to implement.

(Problems to be Solved by the Invention) This invention has been made in an attempt to improve the above-mentioned drawbacks. That is, the present invention was made with the aim of reducing the weight of the blocks, making them easier to handle, and providing blocks for buildings or furniture that can be easily connected to each other without using mortar or the like.

(Means for Solving the Problem) In order to reduce the weight of the block, the inventor decided to make it from synthetic resin. In that case, in order to make the inside of the block hollow, a box-like body with a right-angled rectangular bottom is made, and the box-like bodies of the same shape are made to face each other, and their contact surfaces are glued together to form a hollow body. I thought it was convenient.

In addition, in order to connect the rectangular parallelepiped blocks made in this way to each other, we thought it would be convenient to connect them at the eight corners of the rectangular parallelepiped.

Furthermore, we thought that the connections should be able to be made by simply inserting the connecting pieces from a specific direction.

Based on this idea, this invention was perfected. That is, the present invention is a hollow block in which box-shaped bodies having the same shape and having right-angled bottoms are opposed to each other, and the side walls of the boxes are connected to each other to form an integral body. In addition, a receiving part is formed at the corner of the right-angled quadrilateral in the box-like body, and a fitting hole is provided in the receiving part so that a connecting piece can be inserted therein, so that adjacent blocks can be connected to each other simply by inserting the connecting piece. It is designed to be fixed. for that,
The fitting holes have the same irregular shape and go deeper on the opposing side wall surfaces of the set, and appear in the form of a right angled quadrilateral on the opposing side wall surfaces of the other set. .

(Summary of the Invention) This invention consists of a hollow rectangular parallelepiped that is formed by placing box-like bodies of the same shape with right-angled rectangular bottoms facing each other and connecting the side walls of the boxes to each other. The opposing surfaces are the front or back surfaces, and a groove extending in the direction in which the four side walls are connected is formed on the four side surfaces connected by the connection S, and the side walls of the groove have grooves facing each other at each corner. A receiving portion is provided, each receiving portion having an inset hole, the inset hole extending inwardly with the same cross-section of a different shape on one set of opposing side surfaces, and extending inwardly on one set of opposing side surfaces with the same cross section. ,
The gist is a building or furniture block that is characterized by a right-angled quadrilateral opening.

(Example) The block according to the present invention will be described below based on an example of implementation based on the drawings.

FIG. 1 is a perspective view of a block according to the invention. FIG. 2 is a partially cutaway enlarged perspective view of one box-like body constituting the block according to the present invention. FIG. 3 is a perspective view showing a connected state of blocks according to the present invention. FIG. 4 is a perspective view showing the state in which the block according to the invention is used.

In FIG. 1, the building or furniture block according to the present invention is divided into two parts by a cut plane indicated by a dotted line X.
It is constructed by connecting two box-shaped bodies A and B. The box-like bodies A and B have the same shape, and have a right-angled rectangular bottom l and four side walls C rising from the bottom l. The manner of connection is such that the box-like bodies A and B face each other, the ends of the side walls C are butted against each other, and the abutted portions are glued or fused to be integrated. Therefore, the block thus made consists of a hollow rectangular parallelepiped, with the surface corresponding to the bottom 1 serving as the front or back surface of the block, and the surfaces corresponding to the side walls C serving as side surfaces 2 and 3 of the block.

The box-like bodies A and B only have the receiving parts 4 at the corners, and the side walls C
A large part of the bottom 1 is left inward from the periphery of the bottom 1. Therefore, the side surfaces 2 and 3 of the block are formed with grooves 5 extending in the direction in which the four side surfaces are connected, and the side surfaces of the groove 5 are provided with receiving portions 4 facing each other at each corner. This means that it has been done. The outer surface of the receiving part 4 is along the periphery of the front or back surface l of the block, and is a plane that stands perpendicularly from the periphery. Eight receiving portions 4 are provided for one block.

Each receiving portion 4 is provided with a fitting hole 6.

The fitting hole 6 has a pair of mutually opposing sides, for example,
In FIG. 1, toward the side surface 2 extending in the horizontal direction, it has the same T-shape and goes deeper.

However, the fitting hole 6 is a right-angled quadrilateral at the entrance toward the other pair of mutually opposing side surfaces, the side surface 3 extending in the vertical direction in FIG. It extends perpendicularly to the wall and has a wide-open shape. In other words, the fitting hole 6 is
It has a shape that allows it to be locked.

The shapes of the receiving portion 4 and the fitting hole 6 will be explained in more detail with reference to FIG. As described above, the receiving part 4 is formed at the corner of the bottom l of the box-like body A, and its outer surface 7 stands vertically from the periphery of the bottom 1. When viewed toward the side surface 2, the fitting hole 6 formed in the receiving portion 4 has a T-shape that extends toward the back, but when viewed toward the side surface 3, it is a straight line extending vertically. It looks like it's extending.

This is because the connecting piece 11 having an H-shaped cross section is inserted from the direction toward the side surface 2, and the connecting piece 11 connects adjacent receiving parts. Therefore, in one box-like body or professional body, in the direction in which the side surface 2 extends, the fitting hole 6 is
They are installed symmetrically with the T's head facing inward. Further, the fitting hole 6 is vertically symmetrical in the direction in which the side surface 3 extends.

As is clear from the above description, in order to connect the blocks according to the present invention, it is sufficient to arrange a large number of blocks adjacent to each other and to fit the connecting piece 11 into the fitting hole 6. That is, as shown in FIG.
Connection can be made simply by fitting 1. that time,
The connecting piece 11 is fitted into the adjacent block on the left and right sides of the letter H, but in the vertical direction, only half of the height is embedded, and the other half protrudes from the adjacent block. Then, this protruding portion fits into the lower end of the block placed on it, connecting the blocks in the vertical direction.

In particular, if the blocks are made of synthetic resin, their connections will be easier. In other words, if it is made of synthetic resin, the box-like body can be molded accurately using a mold, so the fitting hole can be accurately formed, and the box-like bodies of the same shape can be placed facing each other and glued together or Blocks can be easily made accurately by fusing. Also,
The fit can be ensured by making the synthetic resin of the block from a hard resin, for example polymethyl methacrylate, while the connecting piece is made from a slightly softer hard resin, for example polyolefin.

Furthermore, in order to use the blocks according to the present invention in buildings or furniture, it is desirable to use a rail-shaped fixing material Y as shown in FIG. Therefore, a fixing member Y having a protrusion that fits into the groove 5 and is fixed by just coming into contact with the inner surface 41 of the receiving part 4 is used. The fixing member Y can be easily fixed onto a building or furniture by driving nails Z into both sides thereof, so that fixing is easy. Then, when the groove 5 of the block is fitted into the protrusion of the fixing member Y, the block is firmly fixed onto the fixing member Y.

Also, in order to fix the flocks located at the ends, the fourth
The connecting piece 12 shown in the figure is used. The connecting piece 12 has a structure in which the connecting piece 11 is cut exactly in half, and has a 7-shaped cross section. By using such a connecting piece 12, blocks that are only vertically adjacent can be fixed to each other.

(Applications) When the block according to the present invention is made of a transparent hard synthetic resin such as polymethyl methacrylate, it can be made as transparent as glass, and has good weather resistance. , it can be used on part of a wall to create a wall for lighting. In addition, it can be used as part of a door or as part of a partition panel.

(Effects of the Invention) The block according to the present invention is composed of a hollow rectangular parallelepiped in which box-shaped bodies having the same shape and having right-angled bottoms are opposed to each other, and the side walls of the boxes are connected to each other. It is easy to manufacture because it is a block, and it is easy to use because its weight is small in proportion to its area. Any pattern can be added to the surface, making it beautiful and versatile. In addition, since grooves are formed on the four side surfaces that extend in the direction in which the four side surfaces are connected, by using a fixing material that has a raised part that fits into the groove, it can be fixed on a building or furniture. can be easily fixed. Further, the side wall of the groove is provided with receiving portions facing each other at each corner, each receiving portion having a fitting hole,
The fitting holes go deeper with the same cross-section of a different shape on one pair of mutually opposing side surfaces, and appear as right-angled openings on the other pair of mutually opposing side surfaces. Adjacent blocks can be easily fixed to each other by inserting a connecting piece having a different shape and the same cross section into the block. Therefore, it is easy to use because the blocks can be fixed to each other by simply inserting the connecting pieces without requiring mortar or adhesive. This invention is
This brings about such benefits.

In addition, when connecting the blocks vertically, it is desirable to provide a locking piece on only one of the abutting parts in order to ensure their contact.The locking piece is designated by number 8 in Figure 2. It is as shown in . The locking piece 8 is provided on the side surface 2 in contact with the edge of the bottom 1, and is positioned so as to protrude slightly upward from the edge, with the front and back surfaces of the block facing each other. The lower end of the block placed on top is guided to ensure that it rests on the front or back surface of the block below.
