Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a block, and more particularly to an improvement of a block that can be stacked in various ways by meshing concave and convex portions provided on a side wall.

(Background of the Related Art) Conventionally, for example, a block that is one of children's toys has a flat surface, and the blocks are simply stacked to complete a desired shape. It is not possible to stack in a small block or hold small blocks between large blocks in a suspended manner, so the stacking method is limited, children's interest in block play tends to fade, and improvement of creativity cannot be expected The block 100 shown in FIGS. 7 and 8 has been improved in response to the above problem.

As shown in the figure, this block 100 is provided with a concave portion 102 and a convex portion 103 on the surface 101a of each side wall 101 ...
The concave portions 102 and the convex portions 103 of 100 and 100 are meshed with each other so that they can be stacked diagonally, and the concave portions 102 and the convex portions 103 are formed in a substantially trapezoidal side surface.

(Problems to be solved by the invention) However, in the block 100 of this type, as shown in the figure, the concave portions 102 ... And the convex portions 103 ... Because it was
The movement in the vertical direction (direction of arrow 300) is not controlled at all, and there is a problem that it is easily displaced.

Also, this kind of block 100 is
When the lines are overlapped as shown in FIG.
Since 104 was not perfect, it was not always possible to form what was intended.

Furthermore, since the concavo-convex portions 102 and 103 of the conventional block 100 have a substantially trapezoidal shape and the tip has an acute angle, it is easy to accidentally get injured.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to enable various stacking methods, and further to prevent slipping in the front-back and left-right directions. This is to solve the problem, and to make it possible to form the side walls on the same line when stacking, and to reduce the risk of injury.

(Means for Solving the Problems) The technical means made by the present invention in order to achieve the above-mentioned object is a desired number of recesses and protrusions so that they are alternately located in the front-rear direction and the left-right direction of the sidewall surface. The concave and convex portions are formed to have a rounded shape, and the tips of the convex portions are aligned with each other with respect to a plane, and the surface provided with the concave convex portions is used as a ground plane to form a self-supporting building block body. It consists of the following:

(Operation and Effect of the Invention) Since the present invention has the above-described configuration, the concave portion and the convex portion provided on the side wall surface of one block become the concave portion and the convex portion on the side wall surface of the other superposed block. Since they are supported by meshing, they can be stacked in various ways, for example, by stacking them diagonally, or by sandwiching small blocks between large blocks in a suspended manner. Since the convex parts and the front and rear and left and right directions of the side wall surface are alternately provided, the displacement of the stacked blocks in the front, back, left, and right directions is controlled by the respective meshing, and the misalignment during the stacking work or after the completion is completed. There is less fear that it will be lost, and it is very excellent for blocks that are one of children's toys or blocks for building materials. Produce an effect.

Since the blocks are aligned so that the tips of the protrusions are aligned with each other as a reference and the surface provided with the protrusions is the ground plane so that the blocks can stand on their own, they are stacked like normal block blocks without engaging the recesses and protrusions. It is also possible to create more diverse stacking forms while selecting whether or not to engage the concave and convex portions.

Further, since the blocks of the present invention can align the lines of each other when they are overlapped, they can be stacked in a desired shape and are very easy to use. Further, since the uneven portion is formed to have a round shape and there is no acute-angled projection on the surface, there is little risk of injury and it is very convenient and useful.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In the figure, A indicates a single block of the present invention, and a desired shape is formed by stacking a plurality of blocks A or a desired number of blocks having other shapes together with the block A, and the illustrated example is a toy. Shows a block for.

The block A is made of a desired synthetic resin such as polyethylene or vinyl chloride resin to form the main body 1 in the shape of a hollow cube.
On the surface of each side wall 1a of the main body 1, the front-back direction (arrow x direction in the figure) and the left-right direction (arrow y direction in the figure) of the surface
The concave portions 2 ... and the convex portions 3 ... are integrally formed with the main body 1 so as to be alternately located in the main body 1,
The concave portion 2 and the convex portion 3 are each formed to have a round shape in a substantially cylindrical shape.

Further, the concave portion 2 and the convex portion 3 are formed on all side surfaces 1a of the main body 1 ...
However, it may be provided only on an arbitrary side surface 1a.

Further, as shown in FIGS. 4 to 6, the front wall 1b and the rear wall
Similarly, 1c may be provided in the up-down direction (arrow Z'direction) and in the left-right direction (arrow Z direction) (FIGS. 4 to 6).

Therefore, even if the front walls 1b are combined, they can be stacked without shifting, and the number of stacking methods is increased, which is very excellent.

Incidentally, the concave portions 2 provided on the front wall 1b and the rear wall 1c, the convex portions 3 are provided.
May be provided only in the vertical direction (arrow Z'direction) or only in the horizontal direction (arrow Z direction) and is not limited.

In the present embodiment, the side walls 1a ... Are thin-walled made of synthetic resin, and the slits 4 ... Are provided on the back side of each of the protrusions 3. 3 ... are elastically meshed and supported to further prevent the slip-off.

Further, in the present embodiment, the description has been made by using a toy and a synthetic resin, but the present invention is not limited to this and may be, for example, a building material, and the material may be rubber, wood, metal or the like. Left and right with part 3 (arrow y direction)
However, the number is not limited to the above, and changes can be freely made within the range easily thought by those skilled in the art.

Therefore, as shown in FIG. 2 and FIG. 3, if arbitrary side surfaces 1a, 1a of blocks A, A having the same shape (cubic shape) are overlapped with each other, the respective concave portions 2 ... And convex portions 3 ... Interlock,
Front-back direction (arrow x direction) and left-right direction (arrow y direction)
Sliding down is prevented, and the side lines 5, 5 or 6, 6 of both blocks A, A are flush.

Further, in the drawing, ten concave portions 2 and convex portions 3 are alternately provided in one side in the arrow y direction.
When the blocks A are formed so that 11 protrusions 3 are provided with 1 cm each, and the blocks A are stacked, the recesses 2 at the end of the block A on the stacking side and the protrusions 3 at the end of the block A on the stacking side are formed. When they are fitted together, the stacking height of both blocks will be 11 cm + 11 cm – 1 cm (for fitting) = 21 cm.

Therefore, if you stack 3 next, 11cm + 11cm + 11cm-2cm = 31cm 4 stack, 11cm + 11cm + 11cm + 11cm-3cm = 41cm, the end is always the same number (1cm in the above example)
It is easier for children to understand when it is used as a toy block if it is increased by 10 cm.

By the way, if you stack 10 blocks A, each of which has a concave portion 2 and a convex portion 3 arranged alternately by 1 cm, 10 cm + 10 cm-1 cm = 19 cm 3 piles, 10 cm + 10 cm + 10 cm-2 cm = 28 cm 4 piles, 10 cm + 10 cm + 10 cm + 10 cm-3 cm = 37 cm The end of the way to increase is also different.

The concave portion 2 and the convex portion 3 are respectively 2 cm, 3 cm, or 10 cm, 20 cm, 3
One that is provided in the direction of the arrow y on one side, such as 0 cm, or 21
1 piece, 31 pieces ..., 22 pieces, 33 pieces ...
It is the same as the one with 11 cm.

In the above example, the cubic block A has been described,
The shape, size, etc. of the plane triangle, the plane circle, the plane trapezoid, etc. are not subject to any restrictions.
