  • Patent number: 9226831
    Abstract: An intervertebral spacer for therapeutic treatment of a patient includes at least one link sized and dimensioned to fit within an intervertebral space in the patient, and is configured to maintain a separation of two adjacent vertebrae for a period of time. A rigid guiding object, which may be a tool or a successive link, is insertable into the patient, to guide other links into the patient using an MIS approach. A pivot is connected between successive links, or between a guide tool and a link, configured to limit a relative range of angular orientation between the link and the guiding tool, or successive links. Multiple links are so joined to form a chain pushable by the last link, and pullable by the first link, to form a chain which may be formed into a curved configuration corresponding to the patient's intervertebral space.

  • Patent number: 6351373
    Abstract: A hinge engages a cam such that the hinge first rotates relative to the cam, then linearly engages the cam. Preferably, the hinge includes a guiding post that rides along a raised arched surface on the cam during the rotary motion of the hinge. Linear motion between the hinge and the cam preferably begins when the guiding post rides off the end of the arched surface. The rotary motion of the hinge is constrained by one or more engagement assemblies. In a preferred embodiment, one or more cams are mounted on a receiving structure and one or more hinges are mounted in corresponding locations on a detaching structure, where said detaching structure is physically separable from the receiving structure. Engagement between the one or more cams and the one or more corresponding hinges allows the detaching structure to first rotate relative to, then linearly engage, the receiving structure, providing for reliable blind mating between connectors on the detaching structure and connectors on the receiving structure.

    Abstract: An artificial knee having a dual flexion action during locomotion is disclosed. The knee comprises a femur part and a tibia part capable of rolling over each other in two different ways depending on whether or not the artificial leg is loaded. Pressure exerted on a cam surface of the femur part flattens the curvature of the cam surface, limiting the angle of rotation of the artificial knee when the knee is loaded. The parts are connected by elastic ties which are fixedly connected to the femur part and movably connected to the tibia part. When the knee is loaded, depending arms from the femur part contact the movable tibia connection and increase the elongation of the elastic ties, thereby additionally resisting rotation.

  • Patent number: 5149222
    Abstract: A rolling flexure bearing. The bearing is formed of a thin sheet of elastic material that is attached to a surface of a first object. The sheet extends a short distance along the surface of the first object. The sheet then makes a 180 degree elastic bend off the surface of the first object to reverse the direction of the sheet. After making the bend, the sheet then extends a short distance along the surface of the second object substantially parallel to the surface of the first object. The sheet is attached at its end to the surface of the second object.In this configuration, the flexure bearing is stiff along an axis parallel to the bend axis to constrain movement along this axis. The flexure bearing, along the axis normal to the surfaces of the objects, has a high compliance rate to provide damping between the objects. Along the third orthogonal axis, normal to the bend axis, the bearing allows free relative movement between the two objects, until it approaches either of the two attachment areas.

The axle has a central elongated tooth portion which meshes with an arrower outer gear carried by a bearing mounted in a housing mounted attached to the frame of the associated vehicle. The bearing allows rotation of the axle while the sliding interengagement between the outer gear and the inner elongated tooth portion allows lateral movement of the axle with respect to the frame of the vehicle. The drive means for applying torque to the axle includes a similar elongated gear meshing with a narrower gear allowing torque to be imparted to the axle at all lateral positions thereof.

  • Patent number: 4815911
    Abstract: A device for torsion-proof connection of a number of elements (11, 12) in direct or indirect rolling contact with each other, which together make a robot arm or the like, whereby the elements are held together and actuated by force transmitting actuators, for example cords. The object of the present invention is to provide a device with which the individual elements of a robot arm can be torsionally locked so that it can bear significant torsional forces without detoriating the rolling characteristics of the elements. This object has been achieved by the fact that the elements (11, 12; 15) pairwise, with their rolling surfaces (13) turned towards each other, being connected with each other through a torsion member (14) which is flexible and/or joined in the rolling direction of the elements (11, 12) and which has a great stiffness across the rolling direction.

  • Patent number: 4460167
    Abstract: The end mounting blocks of full elliptic leaf spring suspension systems are preferably retained by flanged ends on the leaf springs protruding into corresponding openings or slots on the end blocks. The end blocks also include end walls adapted to be abuttingly engageable with the flanged ends. By such a construction, the end blocks are restricted or limited from excessive movement in either a forward or rearward direction relative to the leaf spring ends. The end blocks also include load-receiving members for engaging the ends of the leaf springs whereby the area of load-transferring engagement between the end blocks and the leaf spring ends increases as the leaf springs resiliently deflect under increased load on the suspension system.

  • Patent number: 4294460
    Abstract: A foot-plate for a ski-binding is intended for arrangement at a distance above the surface of a ski and carries the parts of the binding to grip the sole of a ski-boot at front and rear. The foot-plate is connectable to the ski by resilient members to be oscillatory in all directions in its own plane, and also preferably perpendicularly to the surface of the ski. The resilient members may take the form of inserts or bearers, and the foot-plate is advantageously recessed and in each of the recesses there is arranged a resilient member having an aperture for a connecting screw to pass therethrough. These resilient members at the front and rear sections of the foot-plate may have different degrees of resilience.

  • Patent number: 4217474
    Abstract: A simplified linkage and cam member having first and second cam surfaces for interacting with a bail to drive said bail between first and second limits is provided. The cam surfaces restrict the movement of the bail when the bail is at either limit. However, when the bail is intermediate of the limits, the relationship of the effective portions of the cam surfaces allow increased bail movement for a given position of the cam member and associated cam surfaces. The structure is particularly well adapted for actuating a bail from a first to a second position wherein forces other than those applied by the cam also act on the bail; and at a critical bail position, the other forces take control and urge continued motion of the bail independent of the cam member.

  • Patent number: 4206690
    Abstract: In radial piston fluid handling devices, such as for example pumps or motors, piston shoes are pivotable connected to the respective pistons. The invention improves the swing-member portion of the piston shoe in order to increase the efficiency and pressure bearing capability thereby, that the endface of the pivot portion is formed part-cylindrically by a radius which is a little bit shorter than the radius of the associated piston. The fluid pressure balancing pocket in the pivot member becomes formed accordingly, so that the pressure bearing capacity of the piston-piston-shoe pivot-assembly becomes considerably improved.
