An anchor for insertion into an aperture, wherein the anchor includes a body element, two or more elongate engagement members, and a release element. The body element has a first end and an opposed second end, and the body element defines a tapered surface adjacent to a first end portion of the body element. The release element is slidably coupled to the body element. Each of the engagement members has a first end via which the engagement member is coupled to the release element, and a second end which includes a radially outwardly projecting lug. The second ends of the engagement members engage the tapered surface defined by the body element. When the release element is in a release position relative to the body element, the second ends of the engagement members are engaged with a relatively narrow portion of the tapered surface and the lugs are in a radially contracted configuration. When the release element is in an engaged position relative to the body portion, the second ends of the engagement members are engaged with a relatively wide portion of the tapered surface and the lugs are urged radially outwards from the body element by the tapered surface to form a radially expanded configuration.

A fastener comprising: a) a body having: i) a first cylindrical portion with a first diameter, ii) a second cylindrical portion with a second diameter, iii) a shoulder part of the first cylindrical portion, iv) an exterior threaded portion, and v) a cylindrical hole extending along an axis of the body; b) a mandrel having: i) a shank, and ii) a mandrel head at an end of the shank; and c) a head having an opening defined by an interior threaded portion; wherein the mandrel shank at least partially occupies the cylindrical hole of the body; wherein the mandrel head is located outside of the body and opposite of the exterior threaded portion of the body; and wherein the exterior threaded portion of the body and the interior threaded portion of the head are engaged to removably secure the body to the head.

A ball lock pin comprising a pin body with an inner accommodation and at least one locking ball accommodation; a blocking pin at least partly arranged in the inner accommodation and movable between a blocking position and a releasing position; at least one locking ball movably arranged in the at least one locking ball accommodation and biased into a locking position by the blocking pin, if the blocking pin is in the blocking position, wherein the at least one locking ball is released for moving into an unlocking position if the blocking pin is in the releasing position; a primary spring element arranged in the inner accommodation and biasing the blocking pin into the blocking position; and a redundant spring element arranged in the inner accommodation and biasing the blocking pin into the blocking position.

First, please substitute the abstract on the attached new sheet.

Second, please substitute the specification with that shown in the attached Substitute Specification, which includes both clean and markedup copies. The substitute specification moves the text from the originally filed claims into an embodiments section and makes some minor changes referring to claims into references to embodiments.

A tacking fastener for securing workpieces together to form a temporary assembly is provided that includes a stem and a sleeve. The stem includes a proximal end portion, a central portion, and a distal end portion. The stem further includes a head disposed at the proximal end portion, the head defining a distal face having a gripping feature. The sleeve includes a flange disposed at the distal end portion, the flange defining a proximal face having a gripping feature. The sleeve is disposed around the stem and configured to form a tacking rivet upon installation of the tacking fastener. The sleeve is plastically deformed during installation to form a plurality of bulbs, thereby being capable of securing workpieces of varying grip length. The stem and the tacking rivet remain within the workpieces after the workpieces are secured.

A fastener for highly curved access panels on aircraft or other structures, featuring a bottom-grasping design allowing for an unblemished outer panel surface, simple and rapid pneumatic fastener actuation, built-in clamping pre-load, and full retractability of the fastener inside the supporting structure. The fastener includes a Belleville spring with a piston centrally disposed therein, where the piston and spring deflect outward upon application of pneumatic pressure. A pressure chamber within the piston has inlet and outlet orifices designed so that the pressure in the piston chamber gradually increases, requiring several seconds to reach a pressure which causes locking dogs in the piston to deploy radially into a cavity in the access panel. When pressure is removed, the Belleville spring relaxes, the locking dogs grasp a lip of the cavity, and the access panel is latched onto the structure with a clamping pre-load. A pneumatic sequence for unlatching is also provided.

A device for holding a bearing member relative to a fixed body, including a first part having a formation for engagement with a corresponding formation on a fixed body to hold the first part relative to the fixed body, and a receiving formation for receiving and slidably supporting a generally elongate second part, wherein a first end of the second part is configured for engagement with a part of a bearing member to hold the bearing member relative to the fixed body, and wherein a second, opposite, end of the second part supports an abutment member which prevents the first and second parts separating from each other, wherein the device includes biasing means for biasing the first end of the second part away from the first part.

A ball-lock type fastening device for connecting a work piece to a structure is disclosed. The fastening device includes a number of features designed to improve the reliability, repeatability and strength of the locking mechanism compared to traditional ball-lock fasteners. The features include the shape of the locking balls, the shape of the retention housing which engages the locking balls, and mechanisms for controlling deployment and retraction of the locking balls.

A device for setting a temporary fastener. The temporary fastener includes a body with an expandable/retractable end and a rotary element capable of being driven in rotation so as to cause the expandable/retractable end to expand/retract. The device includes a support module that is able to house a temporary fastener and has a holder for holding the temporary fastening inside the module. The holder is movable between at least: a locking position in which the holder is deployed inside the module so as to cooperate with a temporary fastener placed in the module in order to prevent it from moving in translation inside the module, and a rest position in which the holder is retracted so as to allow a temporary fastener to pass through the module.

A clip, for use with structural parts, includes a main tubular body extending along a longitudinal axis and having a bearing face intended contact a first face of the structural parts, a clamp able to pass through opposite perforations, in the parts, and being movable along the longitudinal axis, driven by the rotation of a tie rod having a tapped bore engaging a threaded end of the clamp, the clamp further including branches that are radially and progressively separable along a separator, placed between the branches and fixed relative to the main body, under the effect of the recoil of the clamp, the separator including a transverse part introduced into a longitudinal groove of the clip and rotationally blocked in a groove provided in an element that is fixed relative to the main body.
