Abstract
This invention discloses improvements to the connecting blocks for a kit for assembling toy-like configurations from blocks and solid sticks. The blocks are made in at least two pieces which have contacting surfaces. The one of the contacting surfaces is substantially smooth and the other has grooves therein. When assembled the grooves and adjacent surfaces of the two pieces form holes for the sticks to be inserted into.
Claims25
A kit for building toy-like configurations having at least one selectable geometrical shape, said kit comprising:
- (a) a plurality of blocks having exterior surfaces, each of said exterior surfaces having at least an extreme outer surface portion, a central inner region circumscribed by said extreme outer surface portion;
- at least one aperture on the extreme outer exterior surface of each of said blocks, said at least one aperture defining a hole, said hole having a substantially central longitudinal axis extending from substantially adjacent said outer surface generally toward said central inner region, said hole having a progressive variation in cross-sectional area along said longitudinal axis, the variation resulting in the cross-sectional area being greater adjacent said outer surface and smaller towards said central region;
- and
- (b) plurality of disposable elongated elements being formed of substantially a deformable material and having ends which have a cross section adapted to be insertable into the holes in said blocks at least for interconnecting a selectable portion of said blocks one with the other, said elongated elements having ends with sectional profile dissimilar as compared with the sectional profile of a said hole such that a selectable end of each of said elongated elements in assembly is compressibly grippable by material deformation in and by its corresponding hole at one of at least several locations along said portion of decreasing cross-sectional area of the hole, said blocks each having a first part and a second part;
- said first part having a first contacting surface for making contact with said second part;
- said second part having a second contacting surface for making contact with said first contacting surface;
- said first contacting surface being substantially smooth;
- said second contacting surface having at least one groove therein, said at least one hole being formed in assembly by said groove of said second surface and a portion of said first surface adjacent said at least one groove.

A kit for recreational purposes for the building of at least user-designable objects comprising toy-like configurations having at least one selectable geometrical shape, said kit comprising:
- (a) a plurality of blocks having exterior surfaces, each of said exterior surfaces having at least an extreme outer surface portion, a central inner region circumscribed by said extreme outer surface portion;
- at least one aperture on the extreme outer exterior surface of each of said blocks, said at least one aperture defining a hole, said hole having a substantially central longitudinal axis extending from substantially central longitudinal axis extending from substantially adjacent said outer surface generally toward said central inner region, said hole generally having a cross-sectional area which is greater at said outer surface relative to the hole cross-sectional area at said central inner region, said cross-sectional area progressively decreasing over a length of the hole;
- and;
- (b) a plurality of elongated elements being formed of substantially a deformable material and having ends which have a cross-section adapted to be insertable into the holes in said blocks at least for interconnecting a selectable portion of said blocks one with the other, said hole having such a profile with respect to said cross-section of the elongated elements that a selectable end of each of said elongated elements in assembly is compressibly grippable by deformation in and by its corresponding hole at one of at least several locations along said portion of decreasing cross-sectional area of the hole, each of at least some said plurality of blocks comprising a first part and a substantially similarly shaped but nonidentical second part assembled to form each of at least some of the blocks;
- said first part having a first contacting surface for making contact with said second part;
- said second part having a second contacting surface for making contact with said first contacting surface;
- said first contacting surface being substantially smooth;
- said second contacting surface having at least one groove therein, said at least one hole being formed in assembly by said groove of said second surface and a portion of said first surface adjacent said at least one groove, said first and second parts further having a through hole in each, which through holes facilitate assembly of said first and second parts.
5 more elements
A connecting body for connecting deformable elongated elements, for use in toy kits, said body comprising at least two parts which are substantially similar in shape but are nonidentical, said two parts being assembled by permanently joining them, a first of said parts having a first surface for making contact with a second of said parts,
- a second of said parts having a second surface for making contact on assembly with said first surface of said first part,
- said second surface having a portion with at least one groove therein for accepting, upon assembly of the kit, one end of a said deformable elongated element, the groove being wider at an outer periphery of the second surface and narrowing towards a center region of the second surface,
- a portion of said first surface upon assembly adjacent said one groove being substantially complementary with said one groove to form a hole which is progressively tapering over its length for accepting, upon assembly of the kit, an end of an elongated element by compressible deformation, said hole having such a tapering cross-sectional profile with respect to the cross section of the elongated elements that a selectable end of each of said elongated deformable elements in assembly is compressively grippable at one of at least several locations along said tapering hole.
