TOY BLOCKS
The present invention generally relates to toy blocks, and more specifically, to toy blocks into which other blocks can be easily inserted on sides of each configured block. The present invention suggests toy blocks including hexahedral blocks where convex projections are formed on at least one side while concave grooves inserted into the convex projections are formed on the remaining side.

BACKGROUNDThe present invention generally relates to toy blocks, and more specifically, to toy blocks equipped with concave grooves interference-fitted to convex projections on the rest of sides except one side where the convex projections are formed.
A LEGO product is a representative example of toy blocks. In case of the LEGO product, convex projections are formed on the top while concave grooves interference-fitted to the convex projections are formed on the bottom and the rest of sides are in flat shape. Thus, it is easy to pile up such “LEGO” blocks to the top from the bottom, but it is hard to make shapes which can be extended sideways.
BRIEF SUMMARYIt is therefore an object of the present invention to provide toy blocks capable of inserting other configured blocks from sides of each configured block.
To accomplish the above object, the toy blocks including hexahedral blocks comprise convex projections formed on at least one side, and concave grooves inserted into the convex projections on all of the remaining sides through an interference-fit method.
BRIEF DESCRIPTION OF THE DRAWINGS
Brief Description of important referenced numbers:
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.
Like shown in
In central parts of each side, piercing grooves (15) piercing up to central parts of opposite sides are formed.
It can be confirmed that starting positions and ending positions of the piercing grooves (15) start and end by being further inserted into the inside than positions of planes which constitute each side.
Like shown in
Besides, the convex projections (10) are equipped with vertical grooves (18) piercing through central parts, being formed in divided cylinder shape. Such a shape can solve a defect that the convex projections (10) are removed in the end owing to cracks on bottom sides of the convex projections (10), even though the convex projections (10) are interference-fitted to the concave grooves (11) repeatedly.
The vertical grooves (18) formed on the convex projections (10) are configured in certain depth, so that the grooves cannot reach upper sides of the blocks, consequently overall bottom sides of the convex projections (10) can be adjacent to the upper sides of the blocks. It is shown that the upper sides of the convex projections are divided into more than two parts owing to the vertical grooves passing through the central parts.
Toy blocks of the present invention can be made in various shapes since the toy blocks can be easily inserted in right and left directions as well as up and down directions. Therefore, it is possible to easily make a complex shape in addition to a simple shape, thereby giving considerable interest to children while the children may not be easily bored.
In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
Claims
1. Toy blocks including a hexahedral block, comprising: convex projections formed on at least one side; and concave grooves configured to be inserted into convex projections on all of the remaining sides through an interference-fit method.
2. The toy blocks of claim 1, wherein piercing grooves, which pierce through middle parts of one side that constitutes the hexahedral block and an opposite side opposing the one side, are further comprised.
3. The toy blocks of claim 1, wherein 4 convex projections are disposed on sides where the convex projections are formed.
4. The toy blocks of claim 2, wherein 4 convex projections are disposed on sides where the convex projections are formed, and 4 concave grooves are disposed on each side where the concave grooves are formed.
5. The toy blocks of claim 4, wherein concave spaces are made among neighboring convex projections.
6. The toy blocks of claim 1 or 2, wherein the convex projections are equipped with vertical grooves passing through central parts, so that upper sides of the convex projections are divided into more than two parts.
7. The toy blocks of claim 2, wherein the convex projections are equipped with vertical grooves passing through central parts, so that upper sides of the convex projections are divided into more than two parts.
8. The toy blocks of claim 1, wherein a connection piece equipped with insertion projections inserted into the piercing grooves on both ends, as forming a flat and long plate shape, is further comprised.
9. Toy blocks including a cylindrical block comprising a plane-shaped upper side, a bottom side, and sides, comprising: convex projections formed on the upper side; concave grooves configured to be inserted into convex projections on the bottom side through an interference-fit method; and vertical piercing grooves piercing through the middle of the upper side and the bottom side, first horizontal piercing grooves piercing through central parts of the sides, and second horizontal piercing grooves piercing through the central parts of the sides as being vertical to the first horizontal piercing grooves.
10. The toy blocks of claim 9, wherein a connection piece equipped with insertion projections inserted into the piercing grooves on both ends, as forming a flat and long plate shape, is further comprised.
