Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to a synthetic resin block for buildings or furniture.

(Prior Art) Hollow rectangular parallelepiped blocks made of glass are known as building blocks. These blocks were used to make molds for lighting, etc. by arranging many of them in series with the front or back sides serving as walls.

Mortar was used to attach these building blocks to walls. That is, except for the front or back surfaces of the blocks, mortar was applied to the other four sides, and the mortar was used to connect the blocks to each other and to the walls around the blocks.

However, blocks made of glass are heavy and therefore not easy to handle.

In addition, it had the disadvantage that it was cumbersome to install because mortar had to be used to fix the blocks. The reason for this is that the mortar begins to harden in a short period of time,
And despite this, it takes more than a week to develop sufficient strength.

(Problems to be Solved by the Invention) This invention has been made in an attempt to improve the above-mentioned drawbacks. That is, this invention was made in an attempt to reduce the weight of the blocks to make them easier to handle, and to provide blocks for buildings or furniture that can be easily connected to each other without using mortar or the like, and that are also easy to manufacture. It is something.

(Means for Solving the Problem) In order to reduce the weight of the block, the inventor decided to make it from synthetic resin. Further, in order to facilitate mutual connection, the inventor provided a fitting protrusion on one side of the connecting surface, and provided a drop-in hole on the opposite surface of the connecting surface into which the entire protrusion was inserted, It was decided that the connection would be made using a protrusion and a drop-in hole. In order to further facilitate manufacturing, it was decided to make a hollow block by gluing identical rectangular parallelepiped box-like bodies facing each other.

(Summary of the Invention) This invention is a hollow block made by integrally forming two identical or symmetrical synthetic resin box-like bodies with right-angled bottoms facing each other, each box-like body having an upper A drop-in hole is provided on the outer surface of the side wall, and a protrusion that fits into the drop-in hole is provided on the outer surface of the lower wall facing the upper wall at a position corresponding to the drop-in hole, and the outer surface of the left side wall adjacent to these side walls is provided. It has a separate protrusion on the top, and has a fitting hole that fits with the separate protrusion on the outer surface of the remaining right side wall at a position corresponding to the separate protrusion, and a play hole that extends continuously from the fitting hole toward the upper side wall. The present invention relates to blocks for buildings or furniture, which are characterized by being fully equipped.

An example of implementing a block according to the present invention will be described below based on the drawings. FIG. 1 is a perspective view of a block according to the invention.

FIG. 2 is a perspective view of a box-like body constituting the block of the present invention.

The building or furniture block according to the present invention is a rectangular parallelepiped hollow block as shown in FIG.
The box-shaped bodies A and B made of synthetic resin are placed facing each other and made into one body. Therefore, first, the structure of the box-shaped body A will be explained.

The box-like body A, as shown in FIG. 2, has a right-angled rectangular base 1 around which four sides 92.3.4 and 5 stand upright. The outer surface of the upper wall 2 leaves a protrusion 11 at the same level as the outer periphery of the bottom 1 at a corner close to the bottom 1, and the remaining part is drawn in from the outer periphery of the bottom 1. The result 1. On the outer surface of side v2, a protrusion 11 and a groove wall 12 extending therebetween are formed at the corner.

A drop-in hole 6 is bored in the protrusion 11, and the drop-in hole 6 opens on the outer surface of the side wall 2 in a direction perpendicular to the side wall 2. A locking piece 13 is attached to the inner side of the groove 12.

In FIG. 2, the outer surface of the lower wall 4 facing the upper wall 2 also leaves a protrusion 1 on the same level as the outer periphery of the bottom 1 at the corner close to the bottom 1, and the remaining part is 1 from the outer circumference to the inner side. As a result, the lower i wall 4
Although not shown in FIG. 2, on the outer surface of the upper wall 2
Similar to the outer surface of the projecting portion 11 and the groove wall 12 connecting therebetween
is formed. However, the protruding il on the bottom (11 walls)
l is provided with a protrusion 7, unlike the protrusion 11 on the upper wall 2. The projection 7 stands upright on the outer surface of the lower wall 4 and is attached at a position corresponding to the drop-in hole 6. Therefore, when the box-like bodies are stacked one on top of the other, the protrusion 7 just fits into the drop-in hole 6, and they can be fixed to each other.

As can be inferred from FIG. 2, the left side wall 5 adjacent to the side walls 2 and 4 is also provided with a groove wall 12 that connects the protrusion 11 therebetween, similarly to the side walls 2 and 4. A protrusion 8 is provided on the protrusion 11 on the left side wall 5 as shown in FIG.
The protrusion 8 stands on the outer surface of the left side wall 5 perpendicularly to the outer surface of the side wall 5.The right side wall 8, where the box-shaped body remains, is also connected to the other side walls 2.4 and 2.4, as shown in FIG. 5, it includes a protrusion 11 and a groove wall 12. The protrusion 11 on the right side wall 3 is provided with a fitting hole 9 at a position corresponding to the projection 8, and is provided with a loose hole 10 continuous with the fitting hole 9. The loose fitting hole 1 (lj is connected to the fitting hole 9 and extends in the direction in which the upper wall 2 exists. When the protrusion 8 is inserted into the loose fitting hole 10, there is still a gap, and the fitting hole 9 is This is a hole that can accommodate the entire protrusion 8 without wobbling.

In the above explanation, the words "top, bottom, left, and right" were added to the side walls, but the words "top, bottom, left, and right" here are merely for convenience in order to distinguish between the side walls. For example, the upper wall can replace the lower wall,
Also, the left side wall can be used instead of the right side wall.

To make a block as shown in FIG. 1 using the box A shown in FIG. 2, another box B, which is symmetrical to the box A, is required. Both box-like bodies A and B can be easily made from synthetic resin by injection molding, compression molding, pressure molding, or the like. In order to integrate the box-like bodies A and B, the open ends of the box-like bodies may be fused or bonded together.

The block of the present invention can also be made by using identical box-like bodies A facing each other, instead of using two mutually symmetrical box-like bodies A and B as shown in FIG. For example, a block can be made by making the box-like bodies A shown in FIG. 2 face each other and integrating them so that the side walls 2 are in contact with each other and the side walls 3 and 5 are in contact with each other.

In this case, the side surface of the block formed by connecting the side walls 3 and 5 is provided with a protrusion 8 and a fitting hole 9.
and an engagement hole 10 are provided.

In the block of the present invention, the relationship between the protrusion 7 or id8 and the hole in which it is received is preferably as follows. First, regarding the protrusion 7, the height of the protrusion 7 is made equal to or smaller than the depth of the drop-in hole 6. This is to avoid creating a /j5K gap when blocks are stacked one above the other. Next, the relationship between the height of the protrusion 8 and the depth of the fitting hole 9 is also the same. Also, this
These protrusions and holes must be provided at exactly corresponding positions, and their dimensions must be precisely matched so that there will be no play when fitted together.

Regarding the relationship between the protrusion 8 and the fitting hole 1o, the fitting hole 1o needs to be large enough to receive the protrusion 8 with a sufficient margin. Also, when the protrusion 8 is placed above the fitting hole 9 in the loose fitting hole 10H and inserted into the loose fitting hole 1o, the tip of the protrusion 7 on #W4 is still above the drop-in hole 6. desirable.

Various types of synthetic resins can be used to form the blocks. Among these, preferred are transparent hard resins such as polymethyl methacrylate, polyvinyl chloride-polystyrene, polycarbonate, and thermoplastic polyester resins.

In order to use the block according to the present invention in a building or furniture, it is desirable to use a rail-shaped fixing member Y as shown in FIG. To be more specific, the block has grooves formed on its side surfaces as a result of the groove walls 12 being erected on both sides of the sides. There is. By driving nails Z into both sides of the fixing material Yff, it can be easily fixed onto a building or furniture.

After fixing the fixing member Y in this way, the groove of the block is fitted into the raised portion of the fixing member Y, so that the block can be easily and firmly fixed on a building or furniture.

The locking piece 18 shown in FIG. 2 serves to prevent the upper block from coming off from the lower block when the blocks are stacked one above the other.

This is because the locking piece 18 guides the tip of the groove wall 12 at the lower end of the upper block to surely rest on the groove wall 12 at the upper end of the lower block. In particular, if the protrusion height of the locking piece 13 is made higher than the protrusion height of the protrusion 7, the guiding effect will be more reliable. In addition, the locking piece 13
In FIG. 2, only one port is provided on the upper wall 2, but in reality it is preferable to provide two ports separated from each other on the upper wall 2 (effects of the invention). The block is a hollow block made by facing two identical or symmetrical synthetic resin box-like bodies with right-angled bottoms, so it is lightweight, and its external shape The box-shaped body has a drop hole on the outer surface of the upper wall, and a drop hole on the outer surface of the lower wall facing the upper wall. Since we decided to have all 6 protrusions that fit into the drop-in holes at positions corresponding to , when one block is stacked on top of another block, the protrusions fit into the drop-in holes and become misaligned on the overlapping surface. This allows you to easily and accurately line up the blocks vertically.

Further, the box-like body has a separate protrusion on the outer surface of the left side wall, and a fitting hole that fits with the separate protrusion on the outer surface of the remaining right side wall at a position corresponding to the separate protrusion. G above from the hole
i Since it is equipped with play holes that extend in a row in the wall direction, 1
Line up another block on the side of one block, slightly lift the block with the separate protrusion, insert the separate protrusion into the fitting hole first, and then lower the block.Then, the separate protrusion will fit into the fitting hole. The blocks fit together easily and accurately in the lateral direction. In this way, the block according to this invention can be easily and accurately moved vertically and horizontally! i' I can do Kasuri. In these respects, the block according to the present invention provides significant benefits.
