Abstract:
A single-button coupler comprises a female half coupler and a mating male half coupler that has an injection molded plastic body. The body of the male half coupler has a lengthwise bore. The outer section of the bore is substantially circular, for attachment of a round shaft. The inner section of the bore has a radial opening to the body exterior, within which the button sets. The inner bore section at least has a flat floor, upon which sets the base of the spring that actuates the button. The flat floor preferably runs the whole length of the bore. The flat floor may be at an incline to the lengthwise axis of the male half coupler body. A buttress adjacent the wall at the end of the inner section of the bore helps locate the spring on the flat floor during assembly.

The skirt can form an inner surface (79) shaped to rotatably receive an outer surface (66) of the lock.
Abstract:
A device for fastening an add-on part to a carrier component includes a housing part (10) with a receiving opening (18) and a clip part (20) received therein. The clip part (20) introduced in an introducing direction (E) into the housing part (10) and rotatable about an axis of rotation (D) between locking and unlocking positions. The clip part (20) has latching structure (28) which, in the locking position, protrude outwards relative to the housing part (10) and, in the unlocking position, are accommodated within the housing part (10). With the housing part (10) inserted into the carrier component, the latching structure (28) latch in the locking position on an opening of the carrier component. The clip part (20) is rotatable without deformation between the locking position and the unlocking position. Elastic holding features (11, 25) hold the clip part (20) in the locking position in relation to rotation about the axis of rotation (D) and in relation to an axial movement counter to the introducing direction (E).
Abstract:
A drone docking system (10) for multicopter drone (50) comprises a docking station (20) having a receiver (26). The receiver (26) is adapted to connect to a docking formation (52) mounted atop the drone (50) such that when the drone (50) is docked with the docking station (20), the drone (50) is suspended from and below the docking station (20). A fail-safe mechanical connection (56, 32) is provided to connect the docking formation (52) to the receiver (26). One or more electromagnets (34, 58) may be used to connect the docking formation (52) to the receiver (26), which electromagnets (34, 58) are suitably controllable to provide a smooth transition between docked and free-flight states of the drone (50) and optionally to guide the docking formation (52) into alignment with the receiver (26). The drone (50) suitably has a payload rendering it useful for surveillance and crime prevention/detection purposes.
Abstract:
A connector stud (2) comprising: a base component (4) comprising a base plate (10) and a spacer (12) which projects away from the base plate; a head component (6) comprising a neck portion (20) and a head portion (18), the head portion having a regular polygonal (5) shape; wherein one of the spacer and the neck portion comprises a recess (14) and the other of the spacer and the neck portion comprises a complementary protrusion which is received by the recess; wherein the recess and the protrusion are configured to prevent rotation of the head component relative to the base component; wherein the base component comprises a threaded insert (16) which sits at least partially within a (10) thickness of the spacer for receiving a screw which passes through the neck portion of the head component to fasten the head component to the base component; wherein the base component and the head component are formed from dissimilar materials.
Abstract:
This disclosure relates to a frangible fastener system configured to secure a second retained member to a first retained member until the frangible fastener system receives a breaking force. The frangible fastener system may comprise a first fastener and a second fastener. The first fastener may comprise a flange configured to cause retention of the first retained member toward a base member. The first fastener may be configured to engage the base member and to receive the second fastener along a first axis of the frangible faster system. The second fastener may comprise a frangible portion configured to separate responsive to receiving the breaking force, and a head portion connected to the frangible portion. The head portion may be configured to cause retention of the second retained member toward the first retained member until the frangible portion separates responsive to receiving the breaking force.
Abstract:
A coupler for connecting two segments of a shaft comprises a first fitting (22) and a second fitting (24), each of what is attachable to the end of a shaft segment. The first fitting (22) has at least one spring loaded button (30). The first fitting is received within the cavity of the second fitting. A coupler button has recess in the base for receiving a spring (50) and there are planar button-guiding surfaces (62, 68) within the first fitting. The second fitting preferably has one or more exterior surface flats (42) which align with the direction of button movement and which mate with one or more flats within the second fitting cavity.
Abstract:
Um ein Verfahren zur Herstellung eines Kunststoffbauteils zu schaffen, mittels welchem ein Kunststoffbauteil mit mindestens einem Befestigungsabschnitt zur Befestigung mindestens eines Befestigungselements einfach herstellbar ist, wird vorgeschlagen, dass das Verfahren das Herstellen eines Grundkörpers des Kunststoffbauteils und mindestens eines Befestigungsabschnitts des Grundkörpers in einem einzigen Verfahrensschritt mittels eines Formgebungswerkzeugs umfasst, wobei der Befestigungsabschnitt mindestens eine Aufnahmeöffnung umfasst, in welche ein Befestigungselement zur Festlegung desselben an dem Befestigungsabschnitt in einer Einbringrichtung einbringbar ist, wobei der Befestigungsabschnitt mindestens einen sich in der Einbringrichtung an die Aufnahmeöffnung anschließenden Hinterschneidungsabschnitt umfasst, an welchem das Befestigungselement zur Festlegung desselben entgegen der Einbringrichtung formschlüssig festlegbar ist.
Abstract:
A locking pin for fastening an object by means of an object hole of a predetermined diameter is provided, the pin comprising an elongated shaft having a forward end and a rearward end with a pinhead at the rearward end, a pair of laterally opposed notches formed at a predetermined location along the length of the shaft, wherein the portion of the shaft between the pair of laterally opposed notches is defined as a lock base. A forward hole and at least one rearward hole extend through the lock base proximal to the forward end of the lock base. A wire lock, of a spring-biased wire, is received into the forward hole and rearward hole, the wire lock having forward facing gradually tapered surface along the wire arms from a first end to a second end and a rearward facing abutment surface, when in an uncompressed position.
Abstract:
The present invention relates to a fail-safe locking pin device, and more specifically relates to a fail-safe locking pin device for realising a fail-safe locking device. The fail-safe locking pin device according to the present invention comprises: a housing which is formed integrally on a first body to be locked, and which is formed with a locking guide having a first channel and a second channel that are connected to each other; a locking pin which locks a second body to be locked, that is joined by a hinge to the first body to be locked, and which is formed in the vertical direction together with the locking guide; a coil spring which is mounted around the outside of the locking pin so as to resiliently support the locking pin; and a stopper which is formed on the upper end on one side of the locking pin, horizontally together with the locking guide, and which in a first channel position makes the locking pin establish first-stage locking of the first and second bodies to be locked, and in a second channel position makes the locking pin establish second-stage locking of the first and second bodies to be locked.
