PLAY TOY IN THE FORM OF INTERCHANGEABLE BLOCKS AND METHOD FOR
LOCKING INTERCHANGEABLE BLOCKS
FIELD OF INVENTION
The present invention refers to a toy, more specifically a set of
interchangeable blocks
with a locking method enabled by an additional device, allowing to set up
varied ludic
scenarios by the different shapes in which the blocks are presented, intended
for the
field of toys, motor skills development toys, planning and building skills
development
toys.
BACKGROUND OF THE INVENTION AND PRIOR ART
The first reference to toys in block format goes back to year 1693. There are
wood
models with different shapes that were stacked in order to form something. In
order to
improve the experience and increase stability and length of exposure, some
models
feature fitting devices between modules or blocks.
A solution can be understood by patent application US349646, issued
21/09/1886,
entitled BLOCK, which claimed, a rectangular block with grooves on the top,
which
conform to multiple squares, adapted and designed to receive lower edges from
other
corresponding blocks.
This solution came to be staggered and produced in many different forms in the
product
of the manufacturer INTERLEGO, with numerous patents dating, as from the
middle of
the 20th century.
A different form of interlocking is disclosed in U.S. Patent 3822499, issued
July 9, 1974,
entitled TOY BUILDING BLOCK SUITABLE FOR A PAD, RAFT OR THE LIKE which claimed
a
plurality of semi rigid blocks to form a floating cushion or raft, each block
being cube-
shaped, and may have truncated corners. The faces are provided with a hole to
receive
detachable elements with cylindrical body with spherical heads, allowing it to
be
attached to another block, with the head inserted in its hole.
The national patent application, PI9402723-4, published on 04/02/1996,
entitled TOY,
claimed a toy made of rectangular blocks, each equipped with ditch, on its
bottom,
symmetrical to spike at the top to coupling adjacent blocks.

CA 02987806 2017-11-28

The relevance of the abovennentioned models lies in the stacking form and
lateral
predisposition. The model discussed in US349646, like the overwhelming
majority of
existing blocks, has a face provided with a protruding device and a face with
a
symmetrical recess or that allows it to receive and interlock the
aforementioned
protruding device. Document US3822499 on its turn, requires a certain coupling
ability
between the components, in that, when the detachable member is inserted in the
first
block, by compression of the ball head into the bore, the free, opposing head,
upon
compression of an adjacent block, may press the head into the block to which
the other
head has been interlocked. Although the body is solid and the mentioned hole
has a
limited depth, in view of the structural conformation of the block in semi-
rigid material,
it may cause failure of the head to be coupled with the corresponding hole.
Another drawback of the listed models, except for PI9402723-4, as well as most
interchangeable block toy models, is that the improved locking requires a
greater effort
and technique of the child, incurring in frustration that can trigger
momentary and, even
continuous stress, if successive attempts fail.
ABSTRACT OF THE INVENTION
Taking into account the known elements, the inventor has developed the present
toy,
object of this patent application, hereinafter referred to as LUDIC TOY
INTERCHANGEABLE BUILDING BLOCKS WITH INTERCHANGEABLE BLOCK LOCKING
METHOD, which comprehends blocks made from polymeric material, based on the
quadrangular geometry of a cube with rounded edges, featuring at the common
edge
of two adjacent sides, centered perpendicularly to mentioned sides, one or
more narrow
slots, with a perfect fit to hold 1/4 of the locking device, whose thickness
is equal to or
greater than the width of the aforementioned slot. The block may have the
shape of a
cube, extended to form a cobblestone, or additional shapes, such as that of a
scalene
triangle, a triangle whose longest side is bulged, a trapezoid, a half cube or
a cube with
a cavity. The toy includes disk-shaped locking devices, also offered as a half
disc or a
polygon (quadrilateral, pentagonal, hexagonal, octagonal, among others). The
method
of interaction with the toy consists of the juxtaposition of two or more
blocks, aligning
at least one slot of each block, coupling a locking device and, if desired,
juxtaposing other

CA 02987806 2017-11-28
3
blocks, moving one of its slots towards the exposed portion of the locking
device, which
has the function of providing the immobilization and alignment between
adjacent
blocks, dispensing accurate technique for the engagement and undocking of the
parts.
Blocks and locking devices may be made from polymeric material of varying
densities,
featuring smooth or textured surfaces to improve the grip while handling them,
with
different colors for each of the elements, patterns or colors.
The benefits of this toy in interchangeable block format with flattened
locking device
are many: it develops strength in both fingers and hands, improving hand-eye
coordination, without requiring too much effort; encourages the child to make
friends
and cooperate; encourages interaction; fosters imagination and creativity as
the child
designs and assembles new block sets; intellectually, the child develops
mental potential
as well as his vocabulary, as it describes shapes, sizes, colors and
positions; by grouping
elements, the child develops mathematical skills, adding or subtracting;
sharpens his
perception of the disposition and alignment of blocks; expands his experience
with
gravity, balance and geometry learned by handling the toy blocks.
