TOY BLOCK

摘要

The present invention includes: a base section configured such that, taking the unit edge length D1 to be 1 and a cube expressed as 1×1×1 to be one unit size, the base section has a parallelepiped shape in which one or more 1-unit sizes are conjoined, and is composed of an open, hollow face taken to be the bottom, four lateral walls 3B, and a roof 3A; and cylindrical projections having a cylindrical shape and provided on the outer face of one or more of the roof 3A and the lateral walls 3B, with a diameter D2 being equal to or greater than 0.4 but less than 0.6 with respect to the unit edge length D1, and a height being (1−diameter)×(0.4 to 0.5 inclusive).

主权项

1. A toy block characterized by comprising:
a base section configured such that, taking a unit edge length to be 1 and a cube expressed as 1×1×1 to be one unit size, the base section has a parallelepiped shape of size approximately equal to one or more conjoined unit sizes, and is composed of an open, hollow face taken to be the bottom, four lateral walls, and a roof; and cylindrical projections of a cylindrical shape provided on one or more outer faces of the roof and the lateral walls, with a diameter being equal to or greater than 0.4 but less than 0.6 with respect to the unit edge length, and a height being (1−diameter)×(0.4 to 0.5 inclusive); wherein the base section has an interlocking section that is enclosed by the four lateral walls and by contacting and interlocking with other cylindrical projections of an identical shape to the cylindrical projections, holds the other cylindrical projections; and a wall thickness near the bottom of the lateral walls is expressed as
(1−diameter)×0.5+alpha,where
alpha is between −0.05 and 0.03 inclusive.
