An internal tissue puncture closure method and apparatus. The method and apparatus provide a locking device for compressing and holding an external component such as a collagen sponge at a puncture situs. The locking device facilitates compression of the external component in a first direction, but prevents or locks against retraction.

A jack shaft garage door operator for opening and closing a movable garage door has a drive containing an electric motor. A rotatable jack shaft is connected to the drive unit to be driven thereby. A pull-up cable drum is connected to and driven by the jack shaft. A pull-up cable extends from the drum about which it is wound and connects to a bottom part of the garage door to raise the door. A pivoting arm is mounted near the jack shaft and provides tension to the cable. A shaft lock hub mounted on the jack shaft is engaged and locked by the arm if the tension in the cable drops. A stop is mounted on the garage door for engagement by the movable arm in the event that the door is opened without the cable being drawn in the cable drum.

A length of tubing 22 has a luer 25 connected to one end. The luer 25 includes a lumen 30 of a length to frictionally engage with and seat against a mating recess of a first ophthalmic surgical instrument. A locking hub 36, lockingly engages with a mating structure of a second surgical instrument. This structure then allows the length of tubing 22 to be alternately connected to the first and second ophthalmic surgical instruments and allows the length of tubing 22 to be used on multiple instruments during a single surgical procedure.

Disclosed herein is a delivery system for delivering a leadless pacemaker. The delivery system may include a catheter, which may be a guide catheter. The catheter includes a distal end, a proximal end opposite the distal end, a lumen extending between the distal end and the proximal end, and a locking hub operably coupled to the proximal end. The locking hub includes a lumen segment of the lumen. In one implementation, self-biasing of the lumen segment places the lumen segment out of alignment with a rest of the lumen. Deflecting the lumen segment against the self-biasing of the lumen segment places the lumen segment in coaxial alignment with the rest of the lumen. In another implementation, self-biasing of the lumen segment reduces an inner diameter of the lumen segment and actuation of the locking hub expands the inner diameter.

A collapsible structure with a self-locking mechanism includes a first hub, at least two struts pivotable connected at a first ends thereof to the first hub and movable relative to each another between a folded position and an expanded position, and a tension member adapted to limit pivotable movement of at least two struts such that, when in the expanded position, the at least two struts define an angle of less than 180°. The structure further includes a locking hub and at least two locking struts pivotably connected at first ends thereof to the locking hub and, at seconds ends thereof, to connection points on respective ones of the at least two struts. A method of erecting a structure is also disclosed.

A printing mechanism requires ribbon spools to be locked in place radially, and includes a pivoting ribbon tension arm that must be pivoted out of its normal operating position when ribbon is to be replaced. A ribbon spool lock assembly includes a rotating locking hub on the side of the printing mechanism. The rotating locking hub includes a locking feature that protrudes into the printing mechanism to radially lock the ribbon spool when the locking hub is in a locked position. A pivoting lock arm is provided for pivoting the locking hub into an unlocked position in which the locking feature is disengaged from the ribbon spool.

The invention discloses a hydraulic antiskid self-locking differential mechanism, and belongs to the technical field of differential mechanisms. The hydraulic antiskid self-locking differential mechanism comprises a differential mechanism body and a hydraulic differential lock matched with the differential mechanism body, and the hydraulic differential lock comprises a differential lock hub, a piston rod, a pressure plate and a spline sleeve arranged on a left half shaft inside the differential mechanism body. A driving friction plate and a driven friction plate are arranged outside the spline sleeve. When a tire skids, a piston pushes the piston rod under the action of pressure oil and then pushes the pressure plate to compress the friction plates, a driven spiral bevel gear directly transfers power to the half shaft through a differential mechanism shell, and the differential mechanism body does not work at this moment. The hydraulic antiskid self-locking differential mechanism has the advantages that the structure is simple, manufacturing is easy, and the differential and torque-differential-free function of a common differential mechanism is achieved; when a vehicle skids or falls into mud, the common differential mechanism can be completely locked through the antiskid self-locking function, all torque can be transferred, the vehicle is prevented from skidding, and the trafficability characteristic of the vehicle is improved.

The invention relates to an electrical connector locking hub nut that does not damage the wiring during pulling, frees up manpower by allowing one person rather than two to be able to do the pulling, has a simplified design, and which has universal threading for conduit of all currently approved sizes and materials.

Implementations of the present invention relate to devices, systems, and methods for the safe and efficient use of exercise equipment and, in particular, weight training equipment. A locking hub for weight training equipment may include a first hub and second hub, the first hub and second hub having a sleeve located therebetween. The first hub and/or second hub may hold one or more pads adjacent the sleeve. Rotation of the sleeve relative to the first hub and/or the second hub may compress the one or more pads to force the pads radially inward against a weight bar, substantially restricting movement of the locking hub relative to the weight bar.

This invention relates to a latch assembly 1, and a latch set 1, 2, 3, 4 for use with a sliding door frame 6. The latch assembly 1 includes a housing 48, 49, and a bolt 17 pivotable relative to the housing 48, 49 on rotation of either one of a pair of actuator hubs 51, 52. The latch assembly 1 also includes a pair of locking hubs, 55, 54 which are also rotatable to adjust the lock mechanism between an active condition and an inactive condition.

An automatic transmission comprises a friction engaging means having a plurality of first plates spline-fitted to a hub and a plurality of second plates spline-fitted to a drum and disposed in an interleaving relation to the first plates, an one-way clutch provided in the hub and having a plurality of sprags for locking the rotation of the hub when the hub rotates in a locking direction and a control means for temporarily releasing the friction engaging means for a specified timespan when the friction engaging means is in an engagement condition and when the hub rotates in a locking direction.

A foldable bassinet apparatus includes a bassinet locking mechanism and a bassinet releasing mechanism. The bassinet releasing mechanism is used to actuate the bassinet locking mechanism. The bassinet locking mechanism includes a first hinge component, a second hinge component, an outer capping component and a locking hub component. The second hinge component is rotatably connected to the first hinge component. The outer capping component is rigidly connected to the second hinge component and configured to cap the first hinge component. The locking hub component is slidably located between the first hinge component and the outer capping component. The locking hub component is fully retracted into the first hinge component to allow relative rotation between the first hinge component and the second hinge component, and is further partially protruded from the first hinge component to constrain the relative rotation.
