Extending Keeper Patents (Class 70/96)
  • Patent number: 11187009
    Abstract: A striker assembly includes a housing, a striker, and a spring. The housing has opposed sidewalls, each of which defines an aperture. The striker extends between the sidewalls of the housing with end portions of the striker positioned within respective apertures defined in the sidewalls. Each of the pair of end portions defines a surface extending in a transverse direction. The spring has a pair of end portions. Each spring end portion contacts the surface of a respective striker end portion. The spring is engaged with the housing to bias the end portions of the striker toward a centered position of the respective apertures. At least one of the end portions of the striker is movable transversely within the respective aperture away from the centered position of the respective aperture and is biased toward the centered position of the respective aperture.

  • Patent number: 9003843
    Abstract: Disclosed in one aspect is the fixed door pull handle assembly that includes an elongated door pull handle with two or more support standoffs projecting away from the elongated door pull handle and securing the elongated door pull handle to the doorframe or to the body of the door. One of the support standoffs is user rotatable, and rotatably engages a door latch assembly within the door. In another aspect, the support standoff is not user rotatable. Instead, a center-pivoting handle is mounted in-line with one of the support standoffs and rotatably engages the door latch assembly within the door. The center-pivoting handle is recessed within the elongated handle.

  • Patent number: 8517134
    Abstract: A method for improved engine control is disclosed. The system controls the rate of change of engine RPM, referred to as “ramp rate.” A method provides for controlling the ramp rate of an internal combustion engine including establishing a predetermined rate limit, determining a current engine speed, determining a desired engine speed, and adjusting the speed at or below the predetermined rate limit. In one embodiment, the ramp rate is controlled by an engine control module. The system does not require consideration of vehicle weight. Hence, there is no need for extensive sensors or other means to approximate a vehicle weight. This saves cost and complexity as compared with prior art systems. In another embodiment, the ramp rate control is based on a driver profile or user tier. This allows different ramp rates for different drivers, providing flexibility to have a lower ramp rate for less experienced drivers.

  • Patent number: 8082765
    Abstract: A device (1) maintains a locked and closed state of a space separating device (2) in a releasable manner, in particular a protective device of a machine (4). The device has a first part (6) with an opening and a second part (8). The parts are movable relative to one another. The opening is at least partially closable. The device (1) includes a latch (18) for locking the closed state of the space-separating device (2), a holding element (30) for keeping the latch (18) in the latched position, and a release element (36) for releasing the catch of the latch (18). The catch of the latch (18) may be lifted by a rotational movement of the release element (36) relative to the latch (18).

  • Patent number: 4068874
    Abstract: A locking device for use with a combined handle and rotary latch assembly having a latching hook mounted on an axle stud that is journaled for rotation, in a latch assembly, comprising a locking slide disposed alongside the stud and having a keyhole recess receiving an elongated tab on the end of the axle stud, the recess having a narrow channel portion which slides over the tab in close fitting relation to lock the latch, and having an enlarged circular portion in which the tab can rotate without restriction, to unlock the latch. Yieldable detents restrict motion of the slide from locked to unlocked positions. In one embodiment, the slide is a one-piece molding with a shaped locking recess inside an operating knob, and in another embodiment, a separately formed nylon insert is fitted in the body of the slide to form the locking parts.
