  • Patent number: 5683124
    Abstract: A latching device (5) including a housing (7) with a latching member (15) connected through track followers (16,17) to a track (10,11,12,13,14) in the housing (7). A lever (6) pivotally connected to the housing (7) has a track follower (20) engaged in a track (21) in the latching member (15). A lug (18) on the latching member (15) is disposed adjacent an opening in the housing (7) dimensioned to receive a latch lug (4). Pivotal movement of lever (6) causes movement of follower (2) in the track (21) with resultant planar movement of the latching member (15) as the track followers (16,17) traverse the track (10,11,12,13,14) the shape of which also produces movement of the lug (18) between extended and retracted positions relative to said housing opening.

  • Patent number: 5219195
    Abstract: A closure mechanism for awnings and casement windows includes a flush, pivotal handle with a release mounted in a recessed housing. By depressing the release the handle is pivoted outwardly where it can be easily grasped by the user. Upon closing the window, depressing the handle allows the window to be tightly closed and latched within the frame as the handle is locked into a flush position on the window frame by a pawl which is resiliently urged into a notch in the handle within the housing.

  • Patent number: 5110166
    Abstract: Cranked windows can be retrofitted with a locking system which prevents their forced entry by burglars while still permitting the windows to be opened by a predetermined amount to allow ventilation. Such a retrofitted locking system comprises a case-hardened bolt to disposed through aligned bores drilled through overlapping flanges on a movable fame of the cranked window and the corresponding stationary frame. The bores are drilled through the overlapping flanges at a position in the frames opposite a hinge about which the movable frame rotates. The bores are drilled with a diameter slightly larger than the diameter of the bolt disposed through them to permit the bolt to be inclined, thereby allowing a predetermined degree of opening of the frames relative to each other. An integral head portion of the bolt is disposed outside the movable frame, while the opposing threaded portion of the bolts is provided with a pair of cinched nuts to act as a stop.

  • Patent number: 5080407
    Abstract: A casement window locking system includes a rotatable locking cam mounted in the frame jamb with a window catch access opening on one side and a locking lever access opening on the opposite side. The locking lever has a U-shaped inner end which embraces the locking cam when the two members are engaged and a tab on the locking cam engages a shoulder on the locking lever to prevent withdrawal of the locking lever until a tool is used to raise the locking cam when the tool is inserted through the catch opening. In an alternative embodiment, a spring clip may be placed on top of the locking cam and it includes a shoulder for engaging the shoulder on the locking lever. The removable locking lever makes it possible to install and finish the window without the locking lever and change locking levers to color coordinate with the room interior.

  • Patent number: 4991886
    Abstract: A window lock having plural ramped keepers for a window sash and plural rollers movably associated with a slider mountable on a window frame to provide multi-point locking. The ramped keepers are constructed and related to enable delayed lock-up of one roller and ramped keeper relative to the other in order to assure locking of racked or warped windows. A roller and associated ramped keeper are bevelled to counteract any flexibility that might be encountered in a flexible window, such as a window made of vinyl. The actuating mechanism provides for toggle positioning of the rotatable actuating handle and associated drive link to prevent movement of the lock mechanism by outside forces other than the handle. One or more tie bars, each having a roller, can be associated with the slider to provide for variation in the number of locking points and with further variations being achieved by the length of the tie bars as well as the number of rollers mounted thereon.

  • Patent number: 4703960
    Abstract: The latching bolt of a window lock is pivotally mounted on a slide to pivot between locked and unlocked positions. A reversible motor with a rotary drive shaft is adapted to reciprocate the slide outwardly and inwardly by means of a scotch yoke connection between the drive shaft and the slide, the scotch yoke being of the lost-motion type so as to permit the slide to shift independently of the drive. When the slide is shifted outwardly, the bolt is permitted to pivot to its unlocked position and, when the slide is shifted inwardly, the bolt is cammed to its locked position. A lever may be operated manually to unlock the bolt in the event there is a loss of power to the motor.

  • Patent number: 4635396
    Abstract: A release mechanism for a vehicle escape sash employs a latch mechanism of novel construction, with parts configured as keeper, hinged latch member, and sash bar. The keeper has a keeper flange that projects upward from a web of the keeper, and has a generally cylindrical undercut recess at its juncture with the web. The recess defines a latch seat. The latch member has a sash plate mounted to the window sash rail and a latch plate hingedly connected to the sash plate. A depending flange on the latch plate has a cylindrical head at its free end that fits into the keeper recess and makes continuous rolling contact therewith when the keeper and latch member are latched together. The sash bar is mounted onto the latch plate and extends inwardly over the latch member, the keeper, and the sash subframe. The sash bar both serves as a cover and as a release handle.

  • Patent number: 4621847
    Abstract: A sash lock for a casement window having a case with two sections of different height and with the lower level section having a top wall with a circular segment opening with a curved edge which receives a generally circular part of a rotatable operating member positioned in the opening and extending under a vertical wall interconnecting the two case sections of different height. The rotatable operating member has a curved edge of the same curvature as the curved edge of the case top wall opening as well as a peripheral flange underlying the curved edge of the top wall opening whereby in all rotative positions of the planar operating member the opening is effectively sealed.

  • Patent number: 4429910
    Abstract: A window lock operable in association with either a right-hand or left-hand casement window having a cam movable to either one of two different lock positions relative to a keeper mounted on a window sash. One lock position is operative when the window lock is used with a right-hand casement window and the other lock position is operative when the window lock is used with a left-hand casement window. The movement of the cam is effected by a handle connected thereto by structure including connection means providing a mechanical advantage in movement of the cam by the handle.

  • Patent number: 4313280
    Abstract: A quick opening latch arrangement for hinged vehicle windows in which the window opening that is defined by the vehicle side wall has a sash frame assembly hinged to the window framing at the top of the window opening, and the sash frame assembly along its lower rail is equipped with a latch and release bar hinged thereto for cooperation with a keeper bar in parallelism therewith that is adjustably mounted on the window frame sash subframe. The keeper bar is formed with an elongate bead of cylindrical configuration that is snap fitted in a similarly contoured socket formed in the latch and release bar, to latch the sash frame assembly in its closed position, with the latch assembly being arranged to effectively resist opening under pressures acting outwardly of the window and the sash assembly, while providing for quick release of the latch under a light manually applied pulling action on the latch and release bar.
