Claims
What is claimed is:
1. A set of assembling toys comprising assembling pieces of
flexible, soft and elastic foam synthetic resin cut into suitable
shapes with the circumferential margin of each said piece having
coupling means thereon comprising alternating dovetail cut-out
portions and dovetail setting protrusions whose shapes are
complementary to those of said cut-out portions, whereby any of
said pieces may be joined to another said piece by mating said
respective coupling means optionally in coplanar or in mutually
angular relation.
2. A set as claimed in claim 1, including inlaying pieces of
suitable shapes cut out from said assembling pieces, so as to be
inlaid.
3. A set as claimed in claim 1, including a connecting piece so
provided intermediate two of the assembling pieces as to connect
them by cooperation with their respective coupling means, the
margin of said connecting piece being cut off in such a manner that
a cut-off portion and a setting protrusion alternate with each
other, and the depth of the cut is at least twice the height of the
protrusion of the assembling pieces.
Description
BACKGROUND OF THE INVENTION
The present invention relates to assembling toys in which the
assembling pieces are obtained by cutting foam synthetic resin
material in suitable shapes, and more particularly to such toys
wherein the circumferential margin of said assembling pieces are
cut off at a certain interval in such a manner that a cut-off
portion and a setting protrusion, whose shape conforms to that of
said portion, alternate with each other, and inlaying pieces are
punched or cut out from the assembling pieces.
Thus, the object of the present invention is to provide an
improved, safe and soft educational assembling toys of interest to
children.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention, as well as other objects and advantages thereof will
become more apparent form the following detailed description when
taken in conjugation with the accompanying drawings, in which:
FIG. 1 is a frontal view of the toy assembling arrangement
contemplated herein;
FIG. 2 is a longitudinal sectional view along the line 2--2 of toys
shown in FIG. 1;
FIG. 3 is a cross-sectional view along the line 3--3 of toys shown
in FIG. 1;
FIG. 4 is a slanting view of toys when assembled or joined;
FIG. 5 is an enlarged longitudinal side cut view along the line 5-5
of toys shown in FIG. 4;
FIG. 6 is a frontal view of another embodiment of assembling
toys;
FIG. 7 is a longitudinal sectional view along the line 7--7 of toys
shown in FIG. 6; and
FIG. 8 is a slanting view of toys when assembled or joined.
DETAILED DESCRIPTION
Assembling pieces 1, 1', 1", are obtained by cutting elastic and
non-water absorbing synthetic resin, such as polyethylene or vinyl
chloride, after molding to form a foam structure into suitable
forms such as a triangle, a square, or a rectangle. The cut section
a also is a finished foam structure. (See FIG. 5). The thus
obtained assembling pieces 1, 1' .. are flexible and elastic, and
buoyant on cold and hot water. When they are wetted, water drops
stay about at the top b of the absorptive foam surface. And so, by
applying pressure over the pieces, they adhere to a base plate 13
or other pieces, since a vacuum state is produced in the concave
between the top b in the foam section a.
The circumferential margin of the assembling pieces is cut off in a
certain geometric configuration in such a manner that a cut off
portion 2, 2' .. and a setting protrusion 3, 3' .., whose shape
conforms to the reverse of said cut off portion, alternates with
each other, so as to form mating members.
The assembling piece 1 is connected to the other piece 1' by
fitting or setting its setting protrusions 3, 3' .. into the cut
off portions 2, 2' .. of the other piece, while its cut off portion
2, 2' .. is mated with the protrusions 3 , 3' ... Protrusion and
cut off portions being flexible and elastic, the assembling pieces
are connected with each other detachably at a right angle or with a
gradient. It is also possible to have a connecting piece 4
intermediate to two of the assembling pieces to connect them, as
seen from FIGS. 6 to 8.
The intermediating piece 4 is made of the same synthetic resin
material as that for the assembling pieces, and is provided at its
margin with cut out portions 5 and protrusions 6 of a same height,
but the depth c being twice or even deeper than the height h of the
protrusion 3, 3' .. and of cut off portions 2, 2' .. By using this
piece 4, a simpler but a more solid joining or assembling of
take-apart pieces 1, 1' ..is realized.
Inlaying pieces of various shapes, in turn are obtained by punching
out or cutting out inner parts of the assembling pieces. The pieces
thus obtained such as hole piece 7, decorative piece 8 and smaller
assembling piece 9 are inlaied freely in the respective cut out
hole. Said decorative piece 8 is such that it has a setting
protrusion 10 which may fit in the cut off portions 2, 2' .while
said smaller assembling piece 9 has the same cut out portions 11
and fitting protrusions 12 as those of the assembling pieces.
Thus, according to the inventive concept, assembling pieces are
obtained by cutting foam synthetic resin, with the circumferential
margin being cut at a certain interval in such a manner that a cut
out portion and a setting protrusion, whose shape conforms to the
reverse of said cut out portion, alternates with each other.
Therefore, assembling pieces in various shapes can be connected or
joined securely at right angles or with a gradient with each other
in a simple way, such as fitting setting protrusions of one piece
into cut-out portions of the other. The pieces are so elastic and
light weight that they are pleasant to touch, and safely and easily
assembled. Being made of foam synthetic resin, they are buoyant on
cold and hot water, adhere closely to a wall or to each other when
wetted and pressed. Accordingly, children will take much interest
in joining or pressing them to a wall or to other pieces during
bathing, etc. Furthermore, since inlaying pieces of various shapes
have been cut out from the assembling pieces, a more complicated
building up of structures can be expected.
When they are not used, each of the inlaying pieces are set into
the respective cut-out hole of the assembling pieces, which are
then connected flat so that they may be neatly piled up. In this
way, inlaying parts and assembling pieces do not go disjoined or
scattered while not used.
