Abstract
The disclosure describes a puzzle of the type having a plurality of elongate blocks which may be assembled in an interlocking arrangement. Two of the blocks include a locking mechanism whereby in a first orientation of the assembled puzzle disassembly thereof is prevented while in a second rotated orientation the locking mechanism may be deactivated to permit disassembly.
Claims5
A puzzle comprising an arrangement of elongate blocks each being square and equal in cross section and having the same length, said blocks being provided with suitably located rabbets so as to permit interlocking thereof into an assembled puzzle, two of said blocks being adapted to receive a pair of locking members such that in a first orientation of said assembled puzzle said two blocks and said locking members retain said puzzle in an assembled, locked position and in a second rotated orientation said locking members allows said two blocks to unlock thereby permitting disassembly of said puzzle.
A locking puzzle comprising an arrangement of fourteen elongate, parallelepiped blocks, each block being of the same length and having the same square cross section, twelve of said blocks each having at least two parallel sided recesses therein said recesses extending laterally and having a length equal to the width and a depth equal to one half the width, said twelve blocks adapted to be arranged in an interlocking assembled mode, said remaining two blocks having means cooperating with a pair of locking blocks such that in a first orientation of said assembled puzzle said two blocks and said locking blocks maintain said puzzle locked in an assembled mode and in a second rotated orientation said locking blocks allow said two blocks to unlock thereby permitting disassembly of said puzzle.
A locking puzzle comprising fourteen elongate, parallelepiped blocks, each block being the same length and having equal square cross section, twelve of said blocks having at least two rabbets on one or more sides, said blocks adapted to be assembled in an interlocking manner, said remaining two blocks being adapted to receive a pair of locking blocks therebetween so that said two blocks complete said puzzle whereby in a first orientation of said puzzle said two blocks and said locking blocks retain said puzzle in a locked assembled mode and in a second rotated orientation said locking blocks unlock said two blocks thereby permitting disassembly of said puzzle.
