US 6932669 B2Abstract
providing a mold with a series of individual communicating cavities, a first set of the individual cavities configured to receive a first part, each of the first parts having a first contour, and a second, set of the individual cavities configured to form a second part, each of the second parts having a second contour, with the individual cavities of the first set positioned such that a plurality of individual cavities of the first set alternate with a plurality of individual cavities of the second set, and wherein at least one of the cavities of the first set is bisected by a plane of symmetry between the two adjacent cavities of the second set; marking a plurality of the first parts from a first material having a first melting point; placing the first parts in the first set of cavities with portions of the first parts extending into the second set of cavities; introducing into the second set of cavities a second material having a second melting point which is lower than the first melting point to form the second part, wherein the second material is introduced into the second set of cavities at a temperature that is equal to or higher than the second melting point and lower than the first melting point; allowing the second material to cool in the second cavities to form a plurality of movable joints with the portions of the first parts which extend into the second set of cavities, thereby molding a jointed linkage support system in which the first parts pivot with respect to the second parts without any of the second parts engaging an adjacent one of the second parts; providing the mold with a third set of cavities; marking a switch assembly material having a melting point greater than the second melting point; placing the switch assembly in a cavity of the third set of cavities with a portion of the switch assembly extending into a cavity of the second set of cavities before the second material is introduced into the second set of cavities; and introducing the second material into the second set of cavities to form movable joints with the first parts and the switch assembly. 2. The jointed linkage support system made by the method of claim 1 wherein the second material has a shrink characteristic for gripping the first part.
a second contact element associated with a second switch assembly part, wherein angular movement of the first switch assembly part relative to the second switch assembly part causes the second contact element to engage the first contact element. 5. The jointed linkage support system made by the method of claim 4 wherein the second switch assembly part further comprises a sleeve with a socket formed at one end and the second contact element comprises a conductive annular zing within the sleeve and adjacent the socket.
a spring mounted to and extending from the first end of the shaft, the first contact element being mounted on a distal end of the spring. 7. The jointed linkage support system made by the method of claim 6 further comprising a first electrical lead extending from the second end of the conductive shaft, the first electrical lead being in electrical contact with the first contact element through the shaft and spring; and
For any of these and many other uses, the present jointed linkage support system may take on many different forms. For example, one might use the human body as a model representative of structures which may be built according to the invention. As a generality, the neck, shoulder, and hip joints may rotate and move through a cone of 360� with the apex of the cone having an angle of up to nearly 90� taken with respect to the central axis of the cone. The present invention will satisfy these requirements. Of course, other degrees of motion about the joints are also achievable in the invention.
The ball parts 22 and 22A are made from a first plastic having a relatively high melting temperature of from about 150� C. to 265� C. (and preferably about 175� C. to 265� C.). The socket parts 24 comprise a sleeve made from a second plastic having a lower melting temperature than the high melting temperature of the ball part 22 of from about 110� C. to 175� C. (and preferably about 130� C. to 175� C.). This way, the socket parts 24 may be molded with their sockets 32 and 34 encircling and retaining balls 28 and 30.
Also, the socket part 24 and rod 26 are configured so that the ball part 22A may swivel without having the sleeve of one socket part engage, interfere with, and limit the movement of the sleeve of an adjoining socket part. The movement of the ball part 22A, as it pivots with respect to the axis of the ball and socket member, is indicated by dot-dashed lines on the left side of FIG. 1. In a preferred embodiment, the ball joint part 22A may swing 360� around and within an imaginary conical surface having an apex angle of about 60� taken with respect to an axis 35 of the imaginary cone.

FIG. 12 shows the socket part 222 and ball part 224 oriented in a substantially axially aligned position. As can be seen, contact element 268 is spaced apart from contact ring 250. In this position the electrical switch is open. FIG. 13 shows the ball part 224 angularly displaced relative to the socket part 222. As shown in FIG. 13 the contact element 268 is pivoted against the contact ring 250, thereby closing a circuit across leads 252, 270. Due to the flexibility of spring 266, contact element 268 may be held in engagement with contact ring 250 over a wide range of displacement angles of ball part 224 relative to socket part 222, while simultaneously allowing substantially unrestricted movement of the ball part 224 relative to the socket 222. According to an embodiment of the invention the switch joint allows movement of the ball part 24 of up to 30� from the axis of socket part 222 in any direction.
