## Abstract

Adjacent blocks are biased in directions of mutual contact using elastic cords, the adjacent blocks being changed so that surfaces having mutually different positional relationships are brought into contact with each other in resistance to the biasing force of the elastic cords, whereby the blocks can be transformed between a state of being folded so that the external shape becomes compact, and a state of being extended so as to take on the shape of an object to be expressed. Furthermore, at least two of the blocks among the plurality of blocks have a state in which two surfaces of each of the blocks simultaneously contact each other, the block-type transformable toy thereby being configured so that turning about the elastic cords is limited.

## Claims

### Claim 1

A block-type transformable toy comprising a plurality of adjacent blocks: the adjacent blocks being urged by an elastic cord member in a direction of mutual contact; and so that the block-type transformable toy is transformable between a state of being folded and a state of being extended that the extended shape represents an object, by changing the mutual positional relationships between the adjacent blocks:
at least one pair of the adjacent blocks comprising:
a first block having a first contact surface and a first inclined surface inclining to the first contact surface, the first contact surface and the first inclined surface being next to each other; and
a second block having a second contact surface and a second inclined surface inclining to the second contact surface, the second contact surface and the second inclined surface being next to each other; and able to directly contact with the first contact surface and a first inclined surface of the first block simultaneously;
wherein the first block and the second block contact each other urged by the elastic cord where the first contact surface and the first inclined surface contact with the second contact surface and the second inclined surface simultaneously, and rotational movement of the first block and the second block around the elastic cord member is restricted.

### Claim 2 (depends on 1)

The block-type transformable toy according to claim 1, wherein
the block-type transformable toy is an animal-shaped block-type transformable toy that represents at least a head portion, a torso portion, and a leg portion by way of combining of a plurality of blocks.

### Claim 3 (depends on 2)

The animal-shaped block-type transformable toy according to claim 2, wherein
the two blocks are blocks constituting a head portion and a torso, and displacement of the head portion in a direction of rotational movement with respect to the torso is restricted by the configuration.

### Claim 4 (depends on 1)

The block-type transformable toy according to claim 1, wherein
the state of being folded is configured so that the outer shape is a box shape.

### Claim 5 (depends on 1)

The block-type transformable toy according to claim 1, wherein
an angle between the first contact surface and the first inclined surface is 30 degrees to 170 degrees, and
an angle between the second contact surface and the second inclined surface is 190 degrees to 330 degrees.

### Claim 6 (depends on 1)

The block-type transformable toy according to claim 1, wherein
the two blocks have two or more states in which two surfaces of each are in contact with each other at the same time.

### Claim 7 (depends on 6)

The block-type transformable toy according to claim 6, wherein
the two or more states are, respectively, the state of being folded and the state of being extended.
