  • Patent number: 11415251
    Abstract: A female coupling device includes: a main body, and a clip member coupled to the main body, the clip member having a plurality of arms extending perpendicularly therefrom, with the plurality of arms forming at least one pair of arms, with the pair of arms including a first distance therebetween and a second distance therebetween, with the first distance being sized to engage a clip groove of a mating male coupling device, and with the second distance being sized to disengage the mating male coupling device. In a locked position, the pair of arms is positioned so that the first distance is adjacent to the mating male coupling device. In an unlocked position, the pair of arms is positioned so that the second distance is adjacent to the mating male coupling device.

  • Patent number: 10046324
    Abstract: A motorized latch assembly includes an electric motor, an eccentric cam attached via gears to a shaft of the motor and a latch plate configured to lock the reagent cartridge to the coupler. The eccentric cam is rotated when the shaft of the motor rotates. When the eccentric cam is rotated so that the eccentric cam presses down upon the latch plate, the latch plate moves a sufficient distance to permit the reagent cartridge to be disconnected from the coupler.

  • Patent number: 5765841
    Abstract: An in-line skate with full access frame is provided which includes a skate boot with a sole portion, a two-piece frame secured to the boot sole and a plurality of wheels. The frame includes a first frame portion and a second frame portion cooperating to form a wheel channel when the second frame portion is in a first position adjacent to the first frame portion. The skate wheels are disposed for rotation within the wheel channel. Preferably, the first frame portion is securely connected to the boot sole with the second frame portion movably connected to the first frame portion. The second frame portion is movable from the first position adjacent to the first frame portion to a second position away from the first frame portion to allow access to the wheels. The second frame portion preferably includes at least one connector member sized to be received within a corresponding support cavity or slot in the first frame portion or the boot sole when the second frame portion is in the first position.
