The invention relates to an orthopedic fixation device for securing a rod-like fixation element, with two clamping jaws which can be moved relative to one another and which, when brought together, clamp the fixation element between them. In order to permit space-saving configurations of a fixation device that can be introduced and operated through small orifices in the body, a cam body is provided which is mounted on the fixation device so as to be able to rotate next to the clamping jaws in the direction of tightening and which, when rotated, pushes one clamping jaw toward the other.

A clamp comprises an anvil and a jaw member moveable relative to the anvil between a secured positioned and an unsecured positioned. A driver, which moves the jaw member between the secured and unsecured positions, includes a torque limiter to inhibit overtightening the jaw member against an object. The jaw member has a rigid engagement portion and an elastomeric pad on its engagement surface. In the unsecured position, the elastomeric pad projects above the rigid material such that when the jaw member is brought into contact with the object, the elastomeric pad contacts the object and the object is substantially free of contact with the rigid engagement portion. In the secured position, the elastomeric pad is compressed such that both the elastomeric pad and rigid engagement portion contact the object.

Hole saw boss
InactiveUS7850405B2Avoid over-tighteningThread cutting machinesTransportation and packagingLocking mechanismHole saw
The present invention relates to an improved hole saw boss (10) and in particular, to a boss including a threaded member (12) adapted to accommodate two hole saws of the same or different bore thread diameters. The present invention allows for a pre-existing aperture (22) in a work piece to be simply enlarged. This is useful if a new lock mechanism is being installed in a door with a pre-existing aperture where the lock mechanism requires a larger aperture than that which was in existence. Currently the aperture has to be enlarged by manual handwork since there is no centre-point to which a pilot drill may be enlarged. The threaded bore diameters of the present invention correspond with the commonly available hole saw threaded bore diameters. The present invention therefore provides the public with device for enlarging apertures which is simply, cost effective and can be used with currently available hole saws.

A wrenchless clamp assembly is provided to secure a tool disc, such as a circular saw blade, to a shaft of a power tool. The blade clamp assembly includes an outer flange positionable against an outer side of the blade and a manually tightenable click bolt that includes a movable click member operable to selectively engage the outer flange for rotationally locking or unlocking the bolt. In an embodiment, the click member moves alternatingly between axially engaged and disengaged positions according to sequential rotational increments of the click member relative to the bolt body. Accordingly, the click bolt can be installed by hand and rotationally locked without a need for high torque, and the click bolt can be easily removed by hand when the click member is moved to the disengaged position, axially free from the outer flange. In an embodiment, the click bolt permits limited torque applied during installation.

Clamp and method of making same
InactiveUS20050048640A1Avoid crackingAvoid over-tighteningSnap fastenersBioreactor/fermenter combinationsEngineeringRestoring force
A clamp includes a hoop section and actuating elements. The hoop section forms a cavity for holding a tubular object. The hoop section has first and second ends. First and second actuating elements are respectively coupled with the first and second ends of the hoop section. Squeezing the ends of the actuating members together causes the hoop section to expand to facilitate installation of the clamp onto an object to be clamped and removal of the clamp from the object. Thus, the clamping force generated by the clamp is limited by the restoring forces inherent in the shape, sized, and material of the hoop section when the actuating members are released. The actuating members include expansion limiting extensions which contact each other after a prescribed amount of expansion of the hoop section to thereby prevent further expansion, and possible yielding, of the hoop section. The clamp can be employed as an anti-rotation device secured to a syringe of a syringe pump.

A tightening device and a tightening method are able to check that a fastening member has been fastened to a desired set torque or greater after being tightened, without loosening the fastening member. The tightening device executes a first tightening process of adjusting the output of a motor after measured torque that is measured by a torque detector has reached a preset first control start torque, such that the measured torque reaches a preset first set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the first set torque, and then executes a second tightening process of driving the motor at an initial output that is less than in the first tightening process, adjusting the output of the motor after the measured torque that is measured by the torque detector has reached a preset second control start torque, such that the measured torque reaches a preset second set torque in a phased manner through repeated increases and decreases in torque, and blocking power supply to the motor when the measured torque reaches the second set torque.

Speed nut
This invention describes a speed nut that is formed by three surfaces, a lower surface that is a coupling washer to be pressed against the panel or protective device to which it is attached, an intermediate or base surface, and a final surface that is formed by an arm which, folded back on itself, covers the center of the nut. These surfaces have central holes whose centers are vertically aligned. The nut of the invention has a double screw thread, which consists of the conventional thread of the surface or upper arm and of another thread that is present on the base surface. Both screw threads are created by means of cuts that produce independent flanges of different sizes which together form a helical outline that is designed to mate with the corresponding threading of the screw or bolt that will pass through said nut.
