An expansion bolt comprises a bolt having an end-face anchoring means for the tension-resistant anchoring of the bolt on or in a first assembly part, which bolt has a truncated-cone-shaped cone section and a bolt threaded section in its end section opposite to the anchoring means with a nut screwed thereon, an expansion sleeve having a cylindrical lateral surface and an inner cone contour interacting with the cone section of the bolt, and a clamping device supported on a second assembly part for widening the expansion sleeve and applying an axial clamping force to the assembly parts to be connected together. The cone section of the bolt is tapered in the direction toward its anchoring means and the inner cone contour of the expansion sleeve is tapered in the same direction. The expansion sleeve bears a clamping flange protruding outward in the radial direction on its end opposite to the inner cone contour. The clamping device comprises a clamping ring having an axial passage opening. The expansion sleeve engages through this passage opening, permitting an adjustability of the expansion sleeve in relation to the clamping ring in the axial direction, and protrudes with its clamping flange beyond a peripheral region of the clamping device enclosing the passage opening. The clamping ring also comprises multiple pressure bolts arranged circumferentially distributed, which mesh with their thread in internally threaded holes extending through the clamping ring in the axial direction and act with their bases indirectly or directly against the second assembly part to widen the expansion sleeve and apply an axial clamping force to the assembly parts. Furthermore, a connection assembly having such an expansion bolt is described.

A linear actuation screw having a first end portion, a second end portion on an opposite side as the first end portion, and a sloping intermediate portion between the first end portion and second end portion. The first end portion has a threaded outer wall having a generally constant first diameter over at least a portion of its length and is configured to advance a nut or a sliding member along at least a portion of the first end portion. The second end portion has a threaded outer wall having a generally constant second diameter that is different from the first diameter and is configured to receive a motor fastening nut around it in order to secure the linear actuation screw to a motor. The sloping intermediate portion includes an outer wall that is generally smooth and continuous over at least a majority of the area of the outer wall.

Embodiments are disclosed of an adapter for coupling an implement to a tremor cancellation platform. The adapter includes a first section attached to the tremor cancellation platform, the first section comprising an elongated tapered key having a base and a tip, the base having a greater transverse dimension than the tip and the base being attached to the tremor cancellation platform. The adapter also includes a second section coupled to the implement, the second section including a tapered cavity sized and shaped to receive the first section, and a latch to lock the second section onto the first section.

Techniques are described herein that are capable of enabling a mounting system to receive threaded and threadless posts. The mounting system may have a cavity (a.k.a. void) that is configured to receive such posts. An interior surface of the cavity may include threads to allow corresponding threads of a threaded post to be twisted (e.g., screwed) into the threads of the cavity. The threads of the cavity may be configured to allow a threadless post to pass through the cavity without being encumbered by the threads. The mounting system uses magnetism and a taper of the cavity to facilitate magnetically and frictionally engaging the threadless post in the cavity.

A rivetless nut plate for attachment to a panel via a panel bore, having a nut, a washer, and a cage that retains the nut and the washer. The nut plate has a nonactivated state and an activated state. In the activated state a portion of the cage is expanded to grip the panel bore, and the nut has split into two independent sections allowing one section to move throughout a constrained range of motion.

The invention provides a fastener device comprising a bolt for passing through two adjacent elements. The device comprises an expandable bushing in which the bolt extends, and at least one expander part partially engaged in the expandable bushing in order to cause said bushing to expand radially while tightening the bolt.

A pivoting connection device connecting at least two components and comprising an end fitting having first and second branches, an arm positioned between the first and second branches of the end fitting, a cylindrical axle connecting the end fitting and the arm and having, at one of the ends thereof, a first portion configured to expand radially, a cylindrical rod configured to be screwed into a tapped portion of the cylindrical axle, an insert fitted on the cylindrical rod and movable between a first position, in which the first portion is not expanded, and a second position, in which the first portion is expanded radially, and a nut configured to be screwed on the cylindrical rod to urge the insert into the second position.
