  • Patent number: 6932669
    Abstract: A system for molding a jointed linkage support system with joints that allow movement and bending in many directions and degrees of freedom. A chain-like linkage system made up of a series of joints is molded in a single step from materials having different melting temperatures in a series of alternating communicating mold cavities. The jointed linkage support system emerges from the mold fully assembled. An electrical switch may be provided within one of the joints between sleeves and rods whereby movement of the rod relative to the sleeve actuates the switch.

  • Patent number: 6814566
    Abstract: The invention provides a method of injection molding a part having an undercut region and a method of assembling a jointed structure from several parts. A two-part mold has a common cavity with part of the cavity in each mold part. A combined pin-in-a-sleeve extends into the cavity in one of the mold parts in order to form a bore in a part to be molded in that cavity. The pin provides a portion shaped to form a first undercut region in the bore. A second pin extends into the cavity in the other of the two mold parts. The two pins are aligned to form a single bore in the molded part while in the cavity. The second pin also has a portion shaped to form a second undercut region in the bore. After an injection molded part is made, the mold opens a limited and discrete distance to allow the molded part to be released from the hold of the mold cavity. Then, the mold opens fully for the continuation of a multi-step operation to pull the pins out of the undercut regions.

  • Patent number: 6681472
    Abstract: A method of assembling a jointed structure from several parts is provided. At least two discrete parts having ends that cooperate to form a movable joint between the parts are placed in a groove formed in a plate. The parts are prevented from being displaced out of the groove when pressure is applied to at least one end of the groove to force the cooperating ends of the parts together to form joints which link the parts. The jointed linkage can then be removed from the plate as an assembled structure.

  • Patent number: 6537130
    Abstract: A support system is made up of a plurality of alternating rods and sleeves. Each sleeve forms a pair of sockets configured to movably receive and retain one of the first or second ends of adjacent rods, forming a bendable linkage. A cover is provided to surround the linkage, and a coupler is provided to cover the linkage. An electrical switch may be provided within one of the joints between sleeves and rods whereby movement of the rod relative to the sleeve actuates the switch.

  • Patent number: 6190584
    Abstract: A method of molding, from porous material, a low-density product having an impermeable surface. A mold is provided which has a cavity, the outline of which defines the outline of the product. The starting material is a flat sheet of plastic foam. The first step of the process, in some cases, is a pre-heating procedure, which softens the material. Then, from this sheet there is stamped a blank having substantially the outline of the desired product, which is then inserted into the mold cavity. The mold is then heated with the blank therein to form the blank permanently into the desired product, after which the mold is quenched in cold water with the product still inside. The product is subsequently removed from the mold and frozen. The result of this molding method is a low-density product having an impermeable surface integral with the foam interior which is suitable for receiving various types of brightly colored finished.
