FIG. 10 is a rear view in isometric of the block of FIG. 9; and

FIG. 11 is a plan view of a block which is a modified form of that shown in FIG. 8.

In FIG. 1 is shown a toy assembly 10 made up of a plurality of separate blocklike units 11 which are preferably solid or hollow plastic. Rectangular parallelepiped moldings each representing a separate toy component and each having at least two connection formations at respective opposite ends of the block for assembly with respective other block components. The assembly 10 is made up to represent a mock figure such as a toy clown and the block units composing said mock figure are chosen from a number of different assembly components such as those illustrated in FIGS. 3-11.

Turning first to the components shown in FIGS. 3--ll, in a preferred form of the invention, it is noted that the toy components or blocks 11 may each comprise a hollow or solid injection molding or a hollow blow molding which is substantially rectangular parallelepiped in shape, although by no means is limited to said shape. By providing a rectangular parallelepiped block together with a few odd-shaped blocks, it is noted that the assembly toy provided herein be utilized, in addition to a toy for constructing toy figures and the like, as a conventional block constructional toy of which toy buildings, bridges and other structures may also be assembled by the child. The toy thus provided is actually a three-way toy enabling the user to construct conventional structures, mock comic figures and also as a puzzle in which a particular figure or scene may be derived upon proper assembly of the components.

In FIG. 3, a rectangular block unit 11a is oblong in shape, although it may also be of square shape. Formed at the far ends of the block unit llla are respective protruding formations 12a and 12b which are somewhat cylindrical in shape and are adapted to slide or snap-fit with a cylindrical channel such as 13 shown in FIG. 4 and formed in the end wall of another block 11b to be assembled with Ila. The protrusion 12 at the other end of block 11b is similar in shape to the protrusions 12a and 12b of FIG. 3.

In FIG. 5 the block has cylindrically shaped cavities 13 in each of its end walls and at least two cavities in each of its sidewalls for assembly purposes.

In FIG. 6 the block 11c of FIG. 5 is shown having fasteners 28 assembled in respective cavities of the sidewalls and shaped to protrude beyond the outer surfaces of said sidewalls and to slidably assemble with cylindrical cavities shaped in an adjacent block.

In FIG. 7, each of the sidewalls of a block lId have cylindrically shaped protruding formations formed of the material thereof, there being two such formations l2 protruding from each of the sidewalls and one from each of the end walls in the block llld.

In FIG. 8, three protruding formations 12 are formed in a respective sidewall and end wall and three cylindrical cavities 13 are formed in the other sidewall and end wall.

FIGS. g and I0 illustrate details of a block 11f having a protruding formation I2 in one end wall, a cavity 13 in the other end wall, a cavity and protruding formation in one sidewall and opposed protruding formation and cavity in the other sidewall.

In FIG. 10 a block 11 f is shown from the rear side thereof illustrating that it is hollow. It is noted that two formations of which lIf is one half, may be utilized to form a totally enclosed hollow block by bonding or frictional assembly of two of said block formations after they have been molded to shape.

In FIG. 11, a square block Hg is molded having respective protruding formations 12 in adjacent sidewalls and respective cylindrically shaped cavities or channels 13 in the other two adjacent sidewalls. Indicia' 26A in the form of a number or letter may be printed on one face of the block 11g to permit it to be used to form words or sentences.

Returning now to the assembly III of FIG. 1 which utilizes a number of the components shown in FIGS. 3-ll, it is noted that the head Ilh of the figure is made up of two block formations, the upper one of which has three cylindrical channels, two in one sidewall and one in the other, while the lower block formation has two channels in one wall and a protruding formation in the other which snap or slide assemblies with said channel in the sidewall of the other block formation. A triangular block unit M has a pair of cylindrical protrusions extending from one sidewall thereof which frictionally assemble in the cylindrical grooves or channels in the upper sidewall of the upper block formation defining defining the head of the figure.

The head of the mock figure assembly ll) of HG. is shown having facial features printed on the faces of the two assembled blocks. Eyes are composed of a printed portion in on the upper block and a printed portion W on the lower block which printed portions come into registration upon assembly of the two blocks and indicate the correct mode of assembling said blocks. Eyebrows 15' are printed only on the upper block while a mouth 18 and nose are printed on and confined to the lower block. The shoulders and upper arm portions of the mock figure are composed of blocks 122 of the type shown in FIG. 8, while the forearm portions are composed of respective blocks lib of the type shown in FIG. 4. Although not illustrated, the upper arm and forearm blocks may contain printed illustrations designed to be representative of an extension of the head and neck of the mock figure, as well as illustrations representative of the upper and forearms of the mock figure. Blocks lllg' which are a modified form of the block shown in FIG. ll an containing four, instead of two, cylindrically shaped channels in the sidewalls thereof, are shown assembled at the ends of the forearm blocks ll 1b to represent the hands of the figure. The torso portion of the figure is composed of an oblong block 11d which is a modified form of the block shown in FIG. 7 and three additional blocks including two lib of the type shown in FIG. 4 and lllb which has but one protruding formation 12 at one end thereof. The upper portions of the legs are each formed by a block 11c as shown in FIG. 5 and are connected to the ends of the blocks llb of the torso by means of the connection means or pins 28 shown in FIG. 6 which slidably engage in the cylindrical channels of the blocks 11b and lllc. The lower legs are each formed of blocks Illa of the type shown in FIG. 3 and each connect to a block llllc' which is modified form of the block lie of FIG. 5 having cylindrical channels provided in but one sidewall thereof.

It is noted that additional decorative material may extend across a plurality of those blocks comprising the mock figure of FIG. l which are not illustrated as being decorated if not all of the blocks to define, in much the manner ofajigsaw puzzle, how the component". are intended to be properly assembled together. For exam the blocks illll), llb' and 11d compris ing the torso may be decorated with buttons, pockets and other illustrations representative of the torso of the mock figure. The blocks iic comprising the upper legs may be decorated with indicia such as printed matter representative of the upper legs or pants of the mock figure while the blocks Ila may be printed or spray decorated to represent the lower leg portions of the figure. The blocks lilc' may be surface decorated to represent shoes or feet.

In FIG. 2 is shown an assembly toy 2t? composed of a plurality of substantially rectangular blocks denoted generally by the notation 21 and each molded onto a plurality of gates or runners 25 extending between the sidewalls of adjacent blocks which gates are retained thereon after the blocks are removed from the mold so as to hold said blocks in predetermined assembly such that they may be easily decorated once the assembly is predeterminately located with respect to a printing device such as a roll printing means, a reciprocating plate printing means, screen printing means, a mask for spray painting one or more ofthe blocks or other suitable means.

Each of the blocks 21 of FIG. 2 is substantially a rectangular parallelepiped having one or more sidewalls thereof provided with dovetailed protrusions 23 and one or more of the opposite or same sidewalls containing undercut channel formations 22 of substantially the same shape as the dovetail protrusions to permit sliding engagement of the protrusions of one block with the walls of the channel of the other block and prevent disassembly of the two blocks unless they are laterally moved to disengage the protruding formation from the channel formed in the mating sidewall. Blocks Zia and 21117 are shown having respective illustrations 26a and 2611 which, upon assembly of the blocks, define the head and face of the mock figure or animal denoted 26. A respective pair of dovetailshaped protrusions 23 formed in the upper sidewall of the block Zllb are adapted to be frictionally secured in the dovetail shaped channels or cavities in the lower sidewall of the block 21a. The components 21a and 21b are so gated and decorated that the person purchasing or receiving the gated assembly immediately may see the manner in which the block components are to be assembled.

The torso of the mock animal toy of FIG. 2 is composed of four blocks denoted 21c, 21d, 21g, and 21h which are held in predetermined assembly with each other by respective gate portions of the molding. Legs are defined by block formations Zle, 2llf defining the front legs, while formations-2li and 21] define the rear leg or legs of the figure. The four blocks Zia, 21d, Zllg and 21h which define the torso of the figure are each surface decorated to represent respective portions of the torso of the figure which, upon assembly of the blocks, properly simulate the decorated torso. Said decorations are denoted respectively by the

notations

26c, 26d, 26g, and 26h.

The blocks Zle and 21]" representing the front leg or legs of the figure each contain a

respective decoration

26c and 26f which is representative of the upper portion of the leg or legs of the figure and the lower portion thereof. The blocks 2li and 2H] representing the rear leg or legs of the figure are each decorated with illustrations 261 and 26j representative of the upper and lower leg portions of the figure. A series of blocks Zllk, 211, and 21m are disposed on respective gate portions of the molding and contain illustrative material printed or otherwise deposited on their outer surfaces which represent, upon proper assembly of said blocks, the tail of the mock figure. Notation 22 refers to the dovetail shape channels or cavities molded in the sidewalls of the blocks to permit frictional assembly with the dovetail-shaped protrusions 23 of adjacent blocks.

In a preferred form of the instant invention, blocks of the type shown in FIGS. 2 or 3-H or modified forms of said blocks may be molded in predetermined assembly or respective gates or runners such as that denoted 20 in FIG. 2, retained together on said gates during the decoration process and furthermore, retained together during packaging of said blocks such as underneath a blister or shrink film wrap to indicate to the purchaser the manner in which the components are assembled and furthermore to indicate, rather approximately, the shape of the puzzle upon proper assembly. For example, it is quite obvious that the illustration provided in FIG. 2 is intended to be representative of a cat even though the blocks are separated from each other by respective gate portions 25 as in an exploded drawing. Upon purchase and use of the puzzle, the blocks may be separated from each other by cutting or bending so as to remove the gate portions 25 from the sidewalls of each block, after which the purchaser may either assemble the particular puzzle figure or construct other assemblies of said blocks.

It is to be noted that the block designs illustrated in FIGS. lll may be subject to many different variations in general shape as well as variations in the illustrated means for assembling said blocks together. In addition to mock figures and animals, various other assemblies may be presented including certain representing scenes, houses and other structures containing surface-decorated illustrations which, upon proper assembly of the blocks, provide a picture or object in which the illustrated surface portions match up or are provided in an orderly or predetermined array.

Various articles of manufacture which require decoration upon assembly of a plurality of components may be produced by the means shown in FIG. 2 of the drawings in which the individual molded components of the assembly are retained gated during the decoration process so that if the gated molding is prepositioned relative to the decoration apparatus, each component will also be so prepositioned and a printing means such as a roller, silk screen cut, mask or other means when predeterminately located with respect to one or more of the blocks will provide illustrative material which is prepositioned with respect to the other blocks in the gated assembly in such a manner that, upon proper assembly of the blocks, all of the illustrated material on the various blocks comes into registration or is otherwise properly located to define an article having predetermined shape and decoration upon said assembly. Furthermore, if the gated assembly is retained and prepositioned with respect to an automatic assembly apparatus, said automatic assembly apparatus may be operative to automatically degate or remove the runners from the various components and thereafter predeterminately assemble the components to form articles of predetermined shape which are predeterminately surface-decorated.
