Patent number: 8419309Abstract: A pivoting ball mount provides four essentially equal and (generally) evenly spaced constraints on the ball, creating a ball and socket joint in which the “socket” is composed of four small constraining pads of equal size and equally spaced around the surface of the ball or sphere. If a sphere is constrained by four equidistant points, each point will exert the same amount of force on the sphere. If additional pressure is applied to one point, the pressure exerted by the other points will rise to match this increased pressure. The effect of constraining a smooth ball by four equidistant points is to create the equivalent of a ball and socket joint in which the force required to rotate the ball at a particular rate is about the same in any direction. The ball is constrained by four equidistant points such that the relative movement between the ball and housing is smooth and predictable in any direction.Type: GrantFiled: October 10, 2011Date of Patent: April 16, 2013Assignee: Wimberley, Inc.Inventor: David L.

Patent number: 7325478Abstract: A piston carrier supports an elongated, slender piston rod for reciprocation in a pump cylinder to pump fluid into and out of the cylinder. The piston rod is made of a material such as sapphire or zircon and has a diameter less than about ten millimeters, and the pump can provide flows of from about 50 nanoliters to about 250 microliters per minute at pressures of several hundred bars. A drive motor rotates a threaded screw and a drive nut of a drive system applies a linear drive force to the piston carrier. A ball and socket connection between the drive system and the piston carrier avoids the need for precise alignment to prevent breakage of the fragile piston. A magnet in the socket holds the ball in place and avoids the need for a spring or other mechanical holder. The socket also includes a ring of a low reluctance material surrounding the ball to increase the magnetic retention force.Type: GrantFiled: March 4, 2004Date of Patent: February 5, 2008Assignee: Gilson, Inc.Inventors: Etienne Cautenet, Philippe De Talhouet

Patent number: 7320555Abstract: A cardan shaft structure with tightness adjustable functions has a through-hole passing through spheres located at both ends of the cardan shaft body, and a taper socket respectively installed into the opening end of each sphere. A bolt is inserted into both spheres and the body, fixed and locked together in conjunction with a nut. The cardan shaft structure works together with two clamping components wrapping around the spheres. When the sphere is being pushed against (or freed from) the inner wall of the clamping component by tightening (or loosing) the bolt so as to make the sphere either expand (or recover), the angle displacement of the clamping component becomes adjustable accordingly.Type: GrantFiled: October 14, 2005Date of Patent: January 22, 2008Assignee: Sercomm CorporationInventors: Cheng-Chung Chang, Yi-Fei Yu

Patent number: 7226233Abstract: A snap-in coupling for releasably connecting a first structural member and a second structural member. The snap-in coupling comprises a female coupling member comprising a plastic support member and a metallic spring clamp, said support member being insertable into a socket provided at said first structural member such that the female coupling member is retained therein, and a male coupling member comprising a mounting portion for being fixed to said second structural member, and a head portion. Said spring clamp and said head portion are arranged to snappingly engage each other when said female coupling member and said male coupling member are inserted into each other.Type: GrantFiled: October 12, 2004Date of Patent: June 5, 2007Assignee: Bollhoff Verbindungstechnik GmbHInventors: Rainer SuBenbach, Jochen Rintelmann, Hans-Joachim Dembowsky, Martin Jodeleit

Patent number: 7163181Abstract: A magnetic mounting assembly for securely attaching a positionable object to be variably fixed in a desired selected position to a support, for universally moving the positionable object to the desired selected position, and for holding the positionable object in that position during operation is provided, including a positioning element with a ball that is attached to the positionable object. A support element includes a socket configured to movably engage the ball. One of either the ball or socket includes a magnetic material and the other includes a magnetically attractive material to hold the ball in the socket by magnetic as well as frictional forces. An adjustment collar controls the axial movement of the ball to increase or decrease the magnetic force holding the ball in the socket. This mounting assembly is particularly useful for supporting a camera on a tripod.Type: GrantFiled: December 18, 2002Date of Patent: January 16, 2007Inventor: Justin T. Omps

Patent number: 7121755Abstract: A device for a ball-and-socket-type connection of two members includes a first member having a head and a second member having a cavity that receives the head. The cross-sectional surface of the cavity is tapered at the lower end of the second member as a result of a constriction. The head and/or cavity is configured spherically with a center of articulation (Z). The ball-and-socket-type connection between the two members can be detachably fixed by a clamping element that can be connected to the second member. The head has a recess in which the front end of the clamping element can rest. The recess and/or the front end has an at least partially spherical surface with a centre (C). In the clamped position of the device, the center of articulation (Z) and the centre (C) are identical.Type: GrantFiled: June 30, 2004Date of Patent: October 17, 2006Assignee: Synthes (U.S.A.)Inventors: Fridolin Schlapfer, Renzo Defranceschi

Patent number: 6767153Abstract: A positional arm device is a series of multiple rods connected to each other by a spherical housing and ball joint with a spring-loaded locking piston providing a multiple position holding device serving as an anchor to hold tools in a certain position, and also as a connector between two object where a certain secure fixed position between the two objects is desired. The arm device has a spherical terminal rod, a plurality of intermediate rods and a terminal housing rod connected together by a spherical housing adjustably positioned and locked by a spring-loaded piston shaft engaging a sphere end retained within the housing, the piston shaft lockingly engaging one of a multiplicity of grooved indentations on the surface of the sphere end.Type: GrantFiled: February 10, 2003Date of Patent: July 27, 2004Inventor: Dana W. Holbrook
