A retention system for retaining a milling drum to a driveshaft of a milling assembly. The driveshaft is powered to drive the milling drum about an axis. The retention system includes a retention member coupled to the driveshaft between a first position and a second position. In the first position, the retention member restricts a disengagement between an engagement surface of the driveshaft and a mating surface of the milling drum, inhibiting a release of the milling drum from the driveshaft along the axis. In the second position, the retention member provides clearance for the disengagement of the engagement surface and the mating surface, facilitating the release of the milling drum from the driveshaft along the axis.

A release mechanism for releasably securing a releasable structure to a stationary structure, where the mechanism employs release balls that can re-secure the releasable structure to the stationary structure. The release mechanism includes a base portion having three rails extending radially outward from a center of the base portion, and a rotatable portion rotatably mounted to the base portion, where the rotatable portion has a cam indentation. The release balls are positioned between the base portion and the rotatable portion so that one of the release balls is ridable on each of the rails and all of the release balls are positioned within the cam indentation. The cam indentation is configured so that as the rotatable portion is rotated relative to the base portion the cam indentation causes and allows the release balls to move along the rails in unison with each other to hold and release the releasable structure.

Embodiments of the invention provide a self-sufficient sequential locking device and an injection molding tool. The self-sufficient sequential locking device comprises an elongate body having two ends which are provided with first and second inner engagement elements respectively; first and second outer engagement elements selectably engageable with the first and second inner engagement elements respectively for alternatively establishing a first or a second connection by rotation of the elongate body between a first position in which the first connection is secured and the second connection is simultaneously releasable, and a second position in which the second connection is secured and the first connection is simultaneously releasable, and first and second locking element respectively cooperable with the first and second inner engagement element for securing the first connection when the elongate body is in the first position or the second connection when the elongate body is in the second position.

A storage drive riser may comprise a riser board. The riser board may include an edge connector, a storage drive connector to operably engage with a storage drive, and a retention aperture. The retention aperture may be longitudinally aligned with the storage drive connector. The storage drive riser may also include a storage drive retainer to insertably engage with the retention aperture and to retain the storage drive to the riser board with a retention protrusion.

A fastener structure includes a fastener having a stem portion and at least one movement portion. The stem portion has a fastening section. The movement portion is formed on the stem portion and has a retaining section. With these arrangements, the retaining section of the movement portion can be detachably assembled to a first object and the fastening section can be then detachably assembled or fastened to a second object. In this way, at least two objects can be connected to and disconnected from one another in a quick and repeatable manner.

This disclosure describes a mounting platform comprising a retainer plate opening that includes a first opening profile at a top platform surface of the mounting platform and a second opening profile at a bottom platform surface of the mounting platform. the top platform surface first receives a retainer plate when nested within the mounting platform, and the bottom platform surface abuts the retainer plate when the retainer plate is nested within the mounting platform. The first opening profile matches a planform profile of the retainer plate and is etched into the top platform surface through to the bottom platform surface, and the second opening profile is etched from midway between the top platform surface and the bottom platform surface through to the bottom platform surface. The second opening profile corresponding to a rotational offset of the first opening profile by a predetermined angle.

Please substitute the new Abstract submitted herewith for the original Abstract: A clip for attaching a covering is designed to be introduced in an installation direction into a passage opening, provided for this purpose, of a vehicle component. The clip has a fastening portion which is designed to position and fix the clip at the passage opening when the clip is introduced in the installation direction into the passage opening. The fastening portion has a contact region which is designed to contact an edge of the passage opening. The clip has a coupling portion which is designed to receive an end portion of a pin and to secure the pin against pulling out, and a resilient portion which has at least one resilient element which connects the fastening portion and the coupling portion to each other.

A cam-lock fastening system is designed to accommodate a tolerance stackup to fasten a pair of rigid structures. A spring allows some longitudinal motion of the pin that would not be accommodated by the rigid structures or metal cam-lock and pin. The spring-loaded pin is also suitably designed to produce a preloaded structural joint that is between specified minimum and maximum loads for any tolerance stackup that is within specification. The fastening of the structures requires no manual adjustment of the pin, and facilitates blind connection of a high-fidelity electrical connector. Further, the described cam-lock fastening system is designed for high performance applications requiring preload forces in the thousands of pounds per square inch.

A fastening arrangement having a fastening element for elastically connecting a bolt-on part to a support part. The fastening element has a head section (7) that transitions into an element shank. An elastomer profile part with a retaining groove which is open radially to the outside, into which a retaining foot of the bolt-on part can engage, is arranged on the underside of the head section. The retaining groove is designed with a groove wall on the head side and a groove wall on the shank side. The elastomer profile part is constructed in at least two parts from an elastomer body arranged on the head section of the fastening element and from a disk element that has at least the shank-side groove wall of the retaining groove. The disk element is also composed of two components, namely the elastomer profile part and the hard component.
