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.

A fastener for coupling a first component to a mounting hole of a second component. The fastener includes a central body portion, a head portion, provided at the proximal end of the central body portion. The fastener has at least two resilient ribs, protruding radially outward from an outer surface of the central body portion. The fastener includes at least a first pair of diametrically opposed recessed surfaces, provided at the proximal end of the central body and extending axially between the head portion and a respective shoulder portion formed by each one of the first pair of recessed surfaces. The at least two resilient ribs extend along the outer surface of the central body portion in a direction along the central axis between the distal end and the proximal end, and axially past the respective shoulder portion.

A rotatable connector formed from two parts, each comprising a body extending from a connecting head having a first face and an opposed second face, the second face having an arcuate tail section on an outer perimeter edge and shaped to be received by a tail socket defined between the first face and a pin extending from a proximal end of the body. When the two parts are engaged, the connecting heads are coaxial to define an axis of rotation. When the parts are rotated on the axis relative to one another, the tail section of the first part travels through the tail socket of the second part and the tail section of the second part travels through the tail socket of the first part, thereby connecting the two parts together. When the parts are rotated in the opposite direction, the parts are disconnected from each other.

A scrivet fastener for coupling a panel to a mating structure includes a head, a shaft extending from the head to a distal end of the shaft, and a compliant retention flange. The compliant retention flange extends radially outward from the shaft and is axially spaced apart from the head. The scrivet fastener is configured to at least temporarily couple the panel to the mating structure, such that the distal end of the shaft is secured to a hole of the mating structure and the compliant retention flange is secured to a deformable material of the panel.

In a first aspect there is disclosed a load coupling (10). The load coupling (10) comprises a first coupling member (12) operatively associated with an actuator. The first coupling member has a first coupling formation (16). The load coupling (10) further comprises a second coupling member (14) adapted for operative coupling with the first coupling member (12). The second coupling member (14) includes an attachment formation (15) operatively adapted to attach the second coupling member (14) to a target component to which force generated by the actuator is to be transferred. The second coupling member (14) defines a second coupling formation (24) operatively associated with the first coupling formation (16) of the first coupling member (12). The first coupling formation (16) has (i) a secure orientation relative to the second coupling formation (24) in which the first coupling member (12) is secured to the second coupling member (14) and (ii) a release orientation relative to the second coupling formation (24) in which the first coupling member (12) is adapted to be removed from the second coupling member (14).

A board to board positioning device includes a base including a shaft hole inside, two through hole arranged at two opposite sides perpendicular to the shaft hole and respectively mounted with a limiting ball, a connecting portion and a limiting portion respectively provided at two sides and two limiting grooves for aligning with the two through holes, and an adjustment knob including an operation space for the base to pass through, a sliding wall surface positioned against the through holes, a driving portion positioned against the limiting portion and a marking portion provided on the outside. The sliding wall surface has a pressing side and a retreating side used to push the limiting balls into and out of the through holes. The driving portion is protruded with locking protrusions that are used to rotate and slide along the limiting portion to enter and exit the limiting grooves.

A method of additively manufacturing a fire and overheat detection system (FODS) clamp onto a rail tube is provided. The method includes building a base of a clamp body on the rail tube, sequentially building portions of a locking feature and holders of the clamp body on the base and sequentially building remaining portions of the holders and flanges forming grooves at each of the holders of the clamp body on the base.

An assemblable and disassemblable planter box for propagation, growing, transporting, and planting. The planter box has two sides and a bottom saucer. The sides are attached by engaging assembly a tongue along one edge with a groove formed by side by side lips along a corresponding edge, and inserting locks through the tongue and lips. The bottom saucer attaches the assembled sides to complete the planter box. The bottom saucer may be attached to the sides by bottom saucer locks inserted through bottom saucer slots and into side bottoms. Slots near side tops may receive horizontal planks and diagonal rods reaching up from corner tops help stabilize trees in the planter box. The bottom saucer may includes fork lift passages to facilitate movement of large planter boxes. The sides and bottom saucer may be made from High Density PolyEthylene (HDPE) or from PolyPropylene (PP), both recyclable materials.
