  • Patent number: 9376834
    Abstract: A lock adapted for attachment to a sash window/door without screws comprises: a shaft with a cam secured thereon is rotatably secured to a housing, with the cam disposed within a housing cavity and rotatable therefrom out of an opening, into an extended position. The housing may be a single integrally formed wall that preferably has a flat bottom surface. A first attachment leg protrudes out from the housing cavity to extend beyond the bottom surface, with a foot thereon extending beyond a first end of the housing. A second attachment leg protrudes out the housing cavity second end, with a foot thereon oriented toward the housing first end, and a locking tab extends from the housing bottom surface. Installation of the screwless sash lock is by receiving the first foot, second foot, and locking tab within correspondingly positioned openings in the window/door rail, through sequenced rotational and sliding motion.

  • Patent number: 7604265
    Abstract: A latch assembly for a door includes a housing composed of a base and a cover. A drive knob, two links, two hooks, two adjusting members, and two torsion springs are connected between the base and the cover. The drive knob includes a drive surface that is engaged with a straight inside portion of a through hole of the links. One of the two links is pivotably connected to an adjusting portion of the other link and retaining slot of one of the two hooks. The other link has a positioning portion that is pivotably connected to the retaining slot of the other hook. When the drive knob is rotated in a particular direction (typically counterclockwise), the two links are pivoted in opposite directions and the two hooks are pivoted in two opposite directions and extend through apertures in the first outer surface of the base to hook a keeper structure and secure the door.

  • Patent number: 7506902
    Abstract: An auto-lock mechanism to be mounted on an image input/output device includes a first swingable element and a second swingable element. When the image input/output device is not slantwise and an upper cover of the device is opened, one of the first and second swingable elements swings but does not hook the other of the first and second elements. When the image input/output device is slantwise, both of the first and second swingable elements simultaneously swing, approach and hook each other such that the upper cover remains closed and is free from detachment to hurt a user.

  • Patent number: 7080531
    Abstract: The present invention relates to a latch having a button pawl shaft for attaching two panels together at two different points. The shaft of the latch has bezels in which the shaft rotates connected to one of the panels. The shaft has pawls at both ends which engage a keeper on a second panel and disengage and clear the keeper when a force is applied to the button on the shaft thereby rotating the shaft. A precompressed torsion spring provides a force on the button at all times. When a user presses on the button thereby rotating the shaft such that the pawls disengage with keepers the spring will rotate the shaft and button back to the same position as that prior to the user applying a force on the button.

  • Publication number: 20040169377
    Abstract: A latch device includes a movable member and a housing. The movable member is urged with an urging member to a position where a part of the movable member projects from the housing. When the movable member is pushed into the housing against a force of the urging member, a push-push type lock mechanism turns to a lock state and the movable member is locked at a push-in position. When the movable member in the push-in position is pushed into the housing again against the force of the urging member, the lock mechanism turns to an unlock state, so that the movable member is returned to the projecting position. The lock mechanism is provided on front and back surfaces of the movable member as well as on portions of the housing facing the front and back surfaces of the movable member.

  • Patent number: 5235830
    Abstract: A locking device for a storage container such as a tool box in which a hinged lid includes a pair of spaced detents depending to a latching configuration at their distal ends. Cooperating with the detents is a tubular conduit slidably displaceable and including slots in an upper surface in which to receive and secure the distal ends of the detents. A padlock for unlocking the box is received within a recess of the tool box providing exterior exposure to only the key end of the lock. Opening the padlock causes the lock body to eject partially outward of the tool box while forming a gap between the latching end of the lock shackle and the lock body. Secured to the conduit in the plane of the gap is a manually displaceable wing which when the lock is opened can be displaced into the gap to in turn displace the conduit and enable release of the detents.

  • Patent number: 5078437
    Abstract: An electrical transformer having an integral cabinet with an apparatus for latching and locking the doors of the cabinet. The apparatus is comprised of a three point latch system. The first and second latch points are vertical latch rods which engage sills in the cabinet. The third latch point is a latch plate which rotates with a shaft extending through the first door and to which a handle is attached. In the secured position, the latch plate rotates behind a flange extending from an interior wall, thereby preventing the door from being pulled open. The internal wall divides the cabinet into low and high voltage compartments and forms a structural portion of the cabinet. A bolt extends through the first door, the second door, the latch plate and the flange, thereby preventing the doors from being pulled open and preventing rotation of the handle. A cylinder attached to the first door surrounds the head of the bolt and prevents access thereto.

  • Patent number: 4898409
    Abstract: A tandem rod for use between locking ends of locking handles on a casement window or the like has an elongated bar with two or more brackets slidable thereon. The bar does not have any pre-existing openings by which the brackets can be affixed to the bar. The potential sites for affixing the first bracket onto the bar are infinite. The locking handles can be installed in a window first at any desired location and the tandem rod can then be fitted to the existing location of the locking handles. The tandem rod overcomes the difficulty of installation of previous tandem rods in which the locking handles must be located at pre-determined locations in the bar.

  • Patent number: 4452475
    Abstract: A door with a magnetic sealing strip as a latching means in a refrigerator in a house trailer or the like, may be inadvertently opened when the trailer moves and turns. This is prevented by a movable latching means disposed separately from the latch and arranged under the influence of the force of inertia and against the action of a spring to be brought into a latching position against the door. The force of the spring is selected so as to move the latching means out of engagement with the door when the action of said force of inertia is less than the door latch retaining force.

    Abstract: A detent system is provided for releasably retaining a pair of relatively movable members of a lock assembly or other mechanism in one or more predetermined positions. The members are movable relative to each other to successively present a series of contiguous surface portions on one of the members in spaced, side-by-side relationship with a selected part of the other member. A hole is formed through the part, and a detent element is movably carried in the hole. The detent element has a rounded tip which is projectable from the hole for engaging the contiguous surface portions as the members move relative to each other. A detent receiving formation is provided at a location along the contiguous surface portions and is adapted to receive the rounded tip of the detent element when the members are in a predetermined relative position.
