CROSS REFERENCE TO RELATED APPLICATION
This Patent Application relates to co-pending applications Ser. No. 11/446/776, entitled TOY CONSTRUCTION SYSTEM HAVING A ROTATABLE CONNECTOR JOINT, filed the same date hereof, and Ser. No. 11/446/777, entitled TOY CONSTRUCTION SYSTEM HAVING A COMPOUND CONNECTOR, filed the same date hereof, both by the same inventor hereof.
FIELD OF THE INVENTION
The present invention generally relates to the field of toy building systems and more particularly to an improved system including a joint fixable at a wide variety of angles, thereby enabling the construction of a wide assortment of children's toys and projects.
BACKGROUND OF THE INVENTION
A variety of toy construction systems are available in the market today and described in numerous issued U.S. Patents. Such construction systems commonly have male and female interlocking joints for connecting the various elements together. Although a group of such construction elements can generally be interconnected in a variety of ways, such systems generally have a limitation of the connectors not readily locking in certain orientations, or becoming worn over time, thereby becoming incapable of holding a position at a desired angle.
Exemplary prior art includes U.S. Pat. No. 409,744, entitled TOY BUILDING BLOCKS, which issued Aug. 27, 1889, to A. F. C. Garben. The invention disclosed in this patent relates to building blocks designed for the amusement and instruction of children. The invention includes sphere-headed coupling blocks, which provide a universal joint between pairs of recessed blocks. The result is that any two recessed blocks may be connected in line on a curve or at any angle, and may be held together with sufficient rigidity to make any desired toy structure. A large problem with this invention is that over time the sphere-headed couplings become worn and the objects created will not hold their shape.
Another relevant prior art toy construction system is disclosed in U.S. Pat. Nos. 1,915,835 and 1,916,634, both entitled TOY CONSTRUCTION BLOCK, both of which issued to C. H. PAJEAU on Jun. 27, 1933 and Jul. 4, 1933, respectively. These patents disclose the original “Tinker Toy” building block system, which includes an assortment of relatively inter-fitting elements of varying types that are adapted to be manually assembled into structures and mechanisms of widely varying sizes and types. This invention is somewhat limited in what may be built with the elements.
Still another example of the prior art is disclosed in U.S. Pat. No. 2,622,335, entitled SECTIONAL TOY FIGURE, which issued Dec. 15, 1953 to G. H. Calverley, The disclosed invention relates to sectional toy figures having inter-engagable construction pieces including bodies, heads, limbs, feet and connecting elements. The joints include a socket in the body piece for interconnection with similarly connecting elements. A key problem with this invention is the same as discussed above. Wear on the elements will cause the pieces not to hold their shape.
Yet another prior art example is disclosed in U.S. Pat. No. 3,286,391, entitled CONSTRUCTION TOY HAVING A VARIABLE ANGLE JOINT, which issued to M. Mengeringhausen on Nov. 22, 1966. This patent discloses another joint mechanism for use with toy construction. The invention includes a relatively small spherical connecting member of elastic material having a plurality of substantially cylindrical holes. Again, a key problem with this invention is the same as discussed above. Wear on the elements will cause the pieces not to hold their shape.
Another example of the prior art is disclosed in U.S. Pat. No. 3,458,949, entitled CONSTRUCTION SET, which issued to G. G. Young on Aug. 5, 1969. This patent discloses a terminal unit of spherical shape including a pair of like interlocking members, each having a plurality of circumferential grooves in it. The side walls of each groove, intermediate the ends of the groove, have transversely opposite cavities which form a ball receiving socket. The construction set disclosed in this patent is somewhat limited in what may be constructed.
Many other examples of the prior art are illustrated in issued such U.S. Patents as U.S. Pat. No. 3,510,979, entitled ASSEMBLY KIT, which issued May 12, 1970 to A. Fischer; U.S. Pat. No. 3,747,261, entitled BALL AND ROD LINKAGE FOR JOINING POLYHEDRAL MEMBERS, which issued Jul. 24, 1973 to Nast Salem; U.S. Pat. No. 4,037,978, entitled RESILIENT SWIVEL CONNECTOR, which issued Jul. 26, 1977 to Brian W. Connelly; U.S. Pat. No. 4,078,328, entitled CONSTRUCTION TOY SET, which issued Mar. 14, 1978 to Larry W. Rayment; U.S. Pat. No. 5,897,417, entitled CONSTRUCTION SYSTEM, which issued Apr. 27, 1999 to Michael J. Grey; and, U.S. Pat. No. 6,264,522 B1, entitled CONSTRUCTION SYSTEM, which issued Jul. 24, 2001 to Marilyn M. Dickson.
What is needed is a toy construction system that allows the interconnection of a large variety of components in a large variety of structures or formations in order to foster child development of dexterity and creativity.

Referring now to the drawings and to FIG. 1 in particular, a perspective view of a play house 10 assembled with the novel construction elements of the present invention is shown. The play house 10 may be assembled from a plurality of panels 12, which may include a textured side (e.g., roof shingles or clap-board siding) and an opposite side having a plurality of connector holes 13, which will be explained in greater detail hereinbelow. The structure, including the roof panels 12 are held together with a plurality of blocks 14, each being connected at either end by novel ball connectors 16 in accordance with the present invention.
The play house 10 is constructed on a base platform 17 made up of a multiplicity of panels 12, which may be interlocked by the use of biscuits 18 inserted into slots 20. It is noted that alternatively the biscuits 18 may be fused into an edge of a panel 12 during the manufacture of the toy construction system. This would be preferred if the system were to be used by toddlers who might swallow small parts. A table 22, a lamp 24 and a fan 26 are examples of design elements that may form a part of the toy construction system of the present invention. Also, a design element such as an imitation shrub 28 may be attached to the base platform as well. Each of the design elements just mentioned may be attached to the structure by the use of ball and socket connectors 16, which will be amplified further hereinafter. It is noted that the design elements may also be attached to the structure via twist-lock connectors.
Referring now to FIGS. 2A and 2B, a pair of panels 12 are shown in perspective view. The panel 12 shown in FIG. 2A includes along opposing edges thereof biscuits 18, and along the remaining two edges slots 20 for receiving biscuits of an adjacent panel. On the surface shown of the panel 12 (in both FIGS. 2A and 2B) a multiplicity of connector holes 13 are formed and configured in accordance with the present invention for receiving twist lock pins, which will be amplified hereinafter. It is noted that connector holes 13 may be formed anywhere on a panel 12 (or on any other part of the system components as well) as illustrated along an edge of the panel 12 shown in FIG. 2B.
Turning now to FIGS. 2C through 2G, details of a variety of connectors useful in the practice of the present invention are shown. FIGS. 2D and 2E illustrate a typical biscuit 18 wherein the sides 18A and 18B are each shaped to be received by the slot 20. FIG. 2C illustrates an alternate type of biscuit 18′, wherein one side 18C is shaped in the conventional manner (FIG. 2D) and a second side is shaped into a twist lock pin 30 for receipt by one of the connector holes 13.
With reference to FIG. 2F, details of the twist lock pin 30 are shown. The connector hole 13 is formed with a central core 13A. Also, threads 13C are formed in the slotted connector hole so as to receive mating threads 18E of the biscuit 18′. All of the connector holes 13 shown in the various views are constructed in the same manner as that shown in FIG. 2F and are of the same diameter. FIG. 2G illustrates a threaded connecting pin 32 having threads 32A on one end and threads 328 on the opposite end thereof.
Referring now to FIGS. 3A, 3B and 3C, details are shown of a variety of blocks 33, 34 and 35, respectfully, which are useful in the practice of the present invention. The block 33 shown in FIG. 3A is square in cross section and contains openings 36 formed therethrough. The block 33 may also be rectangular in cross section or any other preferred shape. The openings or holes 36 may be of any shape or size and may be formed in any number, or any location of the system blocks and panels. A circular connector hole 13 may be formed in an end of the block 33. Along a side of the block 33 slots 20 are formed and adapted to receive biscuits (FIG. 2D, e.g.), which slots may be formed in any number or any location of the system components.
The block 34 shown in FIG. 3B is similar to the block 33. However, connector holes 13 are added to the top and along a side in lieu of the slots 20. A third block variation is shown in FIG. 3C, wherein the block 35 is circular in cross section. A connector hole 13 is formed in an end thereof.
Referring now to FIGS. 4A through 4F, details of a variety of ball connectors 16A1 through 16A4 are shown, which are useful in the practice of the present invention. Note that the connector shaft 160 of each of the balls is of the same diameter. This enables standardization of the size of the connector holes 13, but allowing for a variation in the size of the balls connected thereto. FIG. 4E illustrates the shaft 160 with threads 165 in alignment with the connector hole 13. Note also, the hole 13 has a threaded shaft 13C for receiving the threads 165. FIG. 4F is an end view of the shaft 160 showing the threads 165 extending therefrom. It is noted that the balls may be fused onto select pieces in select locations of the toy construction system components by the manufacturer in lieu of making them all separate parts. It is noted that the ball receptacle 30 (or sockets 40) are preferably sized to correspond to the same size balls illustrated in FIGS. 4A through 4D and described hereinabove.
With reference to FIGS. 5A through 5D, details of the novel ball-receptacle 40 of the present invention is shown, which is useful in the practice of the present invention. The ball-receptacle 40 is preferably made of flexible, yet resilient, material such as any type of plastic having memory characteristics.
