Abstract:
A three-dimensional platform comprising a tessellated surface of pieces, each piece comprising a top and sides. The pieces comprise a fixed square piece having at least two opposing sides orientated acutely relative to the top to define a fixed square retention surface. The remaining surfaces orientate substantially perpendicular relative to the top. There is a mobile square piece having at least two opposing sides orientated obtusely relative to the top to define a mobile square retention surface. The remaining surfaces are oriented substantially perpendicular relative to the top. A mobile triangular piece having all sides orientated obtusely relative to the top. The fixed square retention surface indexes only with either the mobile square retention surface or the triangular piece surface to effect retention of the pieces to define the three-dimensional platform.
Abstract:
A chess puzzle provides a chess-type playing surface which has a plurality of spaces located on it. A fixed playing piece is indicated on one or more of these spaces. A placement mechanism associated with the playing surface allows indicating insertable playing pieces on one or more of a selected group of these spaces. The puzzle is solved by manipulating the placement mechanism to indicate insertable playing pieces on the particular spaces where, combined with the fixed playing pieces, a partially-played chess game is presented which satisfies a predetermined criteria.
Abstract:
A geometrical three dimensional puzzle containing grouping of spheres which can be differentiated from each other by texture using the sense of touch, or color and shading by using the sense of sight. The open framework can be made of linear rods intersected perpendicularly by ribs. The open framework may also be made of curved rails. At east one void allows for the spheres to be manipulated and moved around within the open framework. The object of the game is to fill each leg with like colored spheres.
Abstract:
The puzzle apparatus of the present invention presents a challenging logic-based puzzle wherein the user attempts to arrange tiles within one or more chambers until a particular predetermined pattern is achieved (the solution). The apparatus and game play methodology of the present invention differs from that in the prior art in that as the tiles are slid from one matrix column to another the moved tile covers the existing tile located in the matrix column the moving tile is being traveling toward, while the matrix column the moving tile is exiting replaces the moving tile with one located directly underneath it in the matrix column thereby cause a new, unknown tile to replace the moving tile. This added dimension makes it very challenging to arrange the tiles to display a predetermined pattern and achieve the solution. The major elements consist of rigid housing creating a matrix of columns (also referred to as chambers), each chamber containing a base piece attached to a compression spring, multiple sliding tiles, and retaining buttons. The slidable and stackable tiles are interchangeable and relatively arrangeable to produce a solution to the puzzle. The solution includes a predetermined pattern as viewable by the user when looking generally toward the opening of the housing. A method for solving a puzzle in accordance with the invention is also provided.
Abstract:
A spherical puzzle device having two types of surface members positioned around an inner support sphere, wherein the position of each surface member can be moved to the position of any like member. The device may be divided into three sets of opposing domes, with each set of opposing domes being separated by an equatorial band. Thus, both types of surface members can be repositioned by rotating the opposing domes. Further, the domes may be rotated in increments of ninety degrees, after which a different set of domes may be maneuvered. The present puzzle also includes a structure for complete disassembly and reassembly by the user.
Abstract:
To improve the precision of the cooling fine holes of a large-sized and complex-shaped ceramic gas-turbine nozzle with fine cooling holes, a ceramic gas-turbine nozzle with fine cooling holes has a profile degree of 1.0% or less relative to the blade length, a roundness of the fine cooling holes of 0.3 mm or less, and a straightness of the fine cooling holes of 1% or less relative to the blade length. This nozzle is prepared by a method in which two compacts of shroud portions and at least one compact of a blade portion and separately molded are joined by isotropic press molding to be calcined, and the predetermined positions of the resulting calcined compact are subjected to supersonic processing to bore cooling fine holes. The resulting compact is then fired.
Abstract:
A sliding puzzle toy is provided, including a main body and sliders slidably connected to the main body. The main body includes two bottom walls and a side wall, wherein at least one of the two bottom walls is provided with a recessed slot and a separable block, one side of the recessed slot is connected to the side wall, an arc transition is provided at a connection between the recessed slot and the side wall, and the separable block is movably or detachably connected to the recessed slot. The outer surface of the side wall is provided with sliding grooves that intersects with each other along circumferential and longitudinal directions, the sliding grooves are movably connected to the sliders, and one of the longitudinal sliding grooves passes through a connection between the recessed slot and the side wall and extends towards a bottom wall of the recessed slot.
Abstract:
A spherical puzzle comprising a first semi-spherical shell engaged with a second semi-spherical shell. Each shell has four triangular panels held by a plate with the four triangular panels on each plate forming an intersecting track running perpendicularly along an x and y axis. The track on the x axis of the second semi-spherical shell forms a continuous track with the track on the x axis of the first semi-spherical shell and the track on the y axis of the second semi-spherical shell forms a continuous track with the track on the y axis of the first semi-spherical shell. A plurality of sliding tiles forming a predetermined pattern or design are placed on the intersecting tracks. One semi-spherical shell can rotate relative to the other semi-spherical shell about an equatorial axis.
Abstract:
A puzzle device has a round body including at least two intersecting endless runways formed around its external surface and a plurality of intersecting points formed in the intersecting runways; and a plurality of game pieces slidably retained in the runways. The game pieces are moved from one runway to the other runway via the intersecting points so as to position the game pieces in a desired arrangement.
Abstract:
A game assembly in the form of a puzzle comprising a plurality of pieces disconnected from one another but successively positioned and collectively movable along the length of a track structure. Opposite exposed surfaces of the pieces are contrastingly designated such as by different colors or the like and wherein the pieces may be selectively positionable into a predetermined array, for purposes of solving the puzzle, by temporarily disconnecting segments of the track structure along with the pieces thereon and repositioning the track segments into a different operable position from an original operable position.
