The present invention pertains to a hollow rigidly deformable geometric toy with a flat side. The present invention is also directed to a caged silicone toy with a mating joint construction.
Babies and children love to play with blocks, balls, and modular toys. Small children can have a difficult time grasping solid toys, and hollow toys or toys with skeleton structures are lighter, and easier to grasp, grip, and manipulate. In addition, many infants and small children love to put toys in their mouths to gum or chew, and toys with holes, bars, or skeletons can provide surfaces for children to put in their mouths. Toys with skeletons can also be attached via clips to other toys, as well as to cribs, strollers, or other baby gear.
U.S. Pat. Nos. 6,729,984 and 8,052,552 to Silverglate describes a deformable hollow ball having a mesh with loop structures disposed partially around an outer perimeter of each loop structure.
Geometric shapes are educational for young children, as well as pleasing to look at and play with. Toys such as blocks with flat sides can also be stacked in a variety of ways to create shape and structure combinations. Building blocks made of a variety of materials including cardboard, plastic, and wood are known, however hard corners and edges can cause damage or injury when thrown or when structures fall down. Balls with generally curved sides are designed to roll but are not stackable, nor do they provide corners or edges which fit into children's mouths for sucking, teething, or chewing. A geometric toy which is safe for children to put in their mouths and provides the benefits of structure building and mathematical and spatial exploration would be beneficial to children and parents.

For a better understanding of the present invention, as well as other aspects and further features thereof, reference is made to the following description which is to be used in conjunction with the accompanying drawings, where:
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
As used in the specification and claims, the singular forms “a”, “an” and “the” include plural references unless the context clearly dictates otherwise.
The term “comprising” as used herein will be understood to mean that the list following is non-exhaustive and may or may not include any other additional suitable items, for example one or more further feature(s), component(s) and/or element(s) as appropriate.
The term “geometric solid” is a term of art in mathematics that refers to a three dimensional shape having a plurality of surfaces or faces and forming an enclosed space. A face is understood to be a surface that forms part of the boundary of a solid object. Faces in the geometric solid can be planar, such as in a cube, or curved such as in a dome, cylinder, or cone. Although the term “solid” is used herein to describe the shape or configuration of the geometric toy, it is understood that the presently described toy has sides with a plurality of apertures creating a skeleton or cage, and that the toy structure is hollow.
The term “edge” as used herein refers to an extended segment that joins two vertices or faces. In geometric shapes where one of the faces is not flat, such as, for example, a dome or truncated cone, or it is understood that the edge is not required to be a straight line.
The term “vertex” as used herein refers to a point where two or more edges or faces meet. In a cube or rectangular prism, the vertex can also be referred to as a corner.
The term “truncated”, as referring to a vertex of a geometric solid, describes a vertex that has been cut to create a new facet in place of the vertex.
Described is a geometric toy which is hollow and made from a rigidly deformable material. The present invention is also directed to a caged toy with an exterior skeleton and a mating joint construction that is suitable for play for small children and children of all ages. The faces of the geometric toy have apertures which form a skeleton or cage structure which can be grasped by small children. The edges and corners of the geometric toy are suitable for chewing or teething for small children and the material of the toy is safe and suitable for teething as well as play by small children. The geometric toy has at least one flat face which prevents rolling. The flat face also enables the geometric toy to be stacked, or to sit stably on a surface for play. The geometric toy can further enclose an interior toy which cannot be removed through the apertures of the geometric toy to provide additional stimulation and potential functionality to the geometric toy.
Advancements in silicone and plastic mold manufacturing have enabled construction of a wide variety of objects that meet the standards required for children's toys. However, standards required for children's toys are stringent, and extensive testing is required to establish safety. In particular, ASTM standard F963 (Standard Consumer Safety Specification for Toy Safety) requires at least one rigorous physical and/or mechanical test. Depending on the age group playing with the toy, certain strength tests must be passed to ensure safety. In one test called a push-pull test, a clip is placed on an accessible edge of the product, a weight is applied to the clip and the amount of weight is measured which will cause tear or breakage in the object. If the object tears too easily, shore or design must be changed to satisfy the standard such that the toy can be deemed safe.
The presently described geometric toy with hollow interior provides safe encapsulation of an interior toy that children can interact with but not remove the interior toy from the exterior geometric shell structure. A mating joint on at least one edge of the geometric toy provides secure attachment of the components of the geometric toy, and optional secure encapsulation of a toy within. Silicone mold construction with an opening in the shell or cage and complementary mating edges to form a mating joint between the cage components enables secure engagement of the silicone components capable of meeting safety standards for children's toys. The elasticity of silicone, both in its ability to stretch and to revert back to its original shape after stretching, referred to herein as rigidly deformable, allows for manufacturing of aligned and complementary mating edges which hold tightly once engaged. In one preferable mating edge configuration, one of the silicone components of the geometric toy has a channel at its edge and the other complementary component has a projection that aligns with and mates with the channel forming a tongue and groove type mating joint. The secure mating of channel and projection (or tongue and groove) at the edge of the geometric toy secures the components together in a seamless and secure configuration which is suitable and safe for children. In an example, one embodiment of the presently described toy passed the push-pull test at a weight of 15 kg, which exceeds the standard for 3+ months.
Silicone (polysiloxane) manufacturing has so far been challenged to accommodate cage-like structures that can withstand the push-pull forces required to adhere to the ASTM standard for children's toys, and also to securely enclose a smaller interior toy such that the cage can't be deconstructed under normal play or use conditions. 3D printing is also not presently amenable to such structures as printing takes a lot of time and the softer thermoplastics and silicones adapted for 3D printing are not suitable for children's toys. Without being bound by theory, the stretchability (flexibility), tensile strength, and malleability of rigidly deformable materials such as silicone enables the combination of molding, alignment, and adhesion of the mating joint that enables safe and sturdy cage-like structures to be made in a way that satisfies and exceeds the ASTM standard for children's toys. In particular, the silicone components can be stretched to accommodate fitting of the mating joint, and allow contraction to engage a snug fit. Placement of the joint in an interior of an edge of the toy provides further strength, directs any additional silicone adhesive to a hidden seam inside the construction edge, and provides a nearly invisible or invisible seam where the two parts meet. Silicone comes in various shores, which determine the firmness, or hardness or softness of the silicone. Acceptable shores for the present application are between 30-90 shore, and preferably 50-70 shore, with selection of the shore based on the required combination of stretchability, strength, tensile strength, and shape maintenance upon contraction.
Silicone can be washed in a conventional dishwasher and can withstand disinfection or sterilization temperatures. Silicone is further safe for babies and children to chew on, and more flexible than other polymers used for children's toys, which enables children to squish, grasp or chew. Silicone is also available in food grade and medical grade which is safe for infants and children who like to gum or chew on their toys. Silicone can be made BPA-free phthalate-free, metal-free, is latex-free and food-safe. Malleable toys have lower chance of injury when thrown and soft or bendable toys prevent damage to furniture for indoor play. Polymer toys can also bounce and can have a surface friction which supports structure building and stacking.
The construction of geometric toy 10, in this case a cube, is preferably accomplished with two molded pieces, a first piece with five sides and an open face, and a second piece having a single face. The open face of the first piece has a mating edge which is complementary to the outside edge or perimeter of the second piece. During construction, stretching of the open face of the first piece allows engagement of the mating edge of the first piece with the mating edge on the outside edge of the second piece, and releasing the stretch on the first piece allows for full engagement of the mating joint between the first and second pieces. The seam of the mating joint can be visible or invisible based on the placement of the mating joint on the two pieces, and the non-mating edges of the first piece can be textured to simulate a line or joint to further hide the location of the mating joint in the assembled structure. The mating joint can be further stabilized with an optional additional adhesive, applied during construction of the geometric toy.
The geometric toys described can further have means for attachment one to the other. Suction elements, nubs and aligned indentations, mating protrusions and holes, and elongated protrusions and mating indentations on one or more edges, faces, and/or vertices, can all be used to provide reversible attachment locations to support stacking or temporary attachment of two or more geometric toys. The high friction nature of silicone further enables mating and stacking of elements and prevents slipping of one silicone toy relative to another, or relative to a surface. Connector parts can further be on a part on the interior of the geometric toy such that two geometric toys can be releasably connected. These can include mateable features such as, for example, complementary pegs and holes. Friction fit of these complementary features can enable secure but releasable connection by small children. Alternatively, the geometric toy can also be provided together with clips, joins, hooks, clamps, or connector rings, to reversibly secure two or more geometric toys together, or to releasably attach one or more geometric toy to another toy or piece of baby gear such as a high chair, stroller, crib, car-seat, or play structure. Other accessories can be provided including with adjacent holes or connection regions, which can be placed at a variety of locations or orientations on the geometric toy. Various lightweight structures can safely built with the present geometric toys by users of all ages. The structures can either be freestanding, with multiple toys balanced on one another, or connected by way of connector parts which are either attached or integrated into the skeleton structure of the geometric toys or can be attached and removed from the toy skeletons. Multiple toys can also be permanently connected through their vertices and sold in chains of 2, 3, 4 or more. In particular, two geometric toys can be connected through the respective apertures on an edge or vertex such that the toys are linked. The geometric toys can further have one or more features to releasably secure the toy to a surface such as suction elements. Integrated surface features such as indentations can serve as suction elements when the geometric toy is made of a deformable material, especially when played with in a bath or pool with flat or tiled we surfaces. The toy can be any color, or combination of colors.
