  • Patent number: 4315647
    Abstract: A flush bolt is disclosed which is adapted for flush mounting on a door. The flush bolt is composed of a latch sled and faceplate. Both the latch sled and faceplate may be constructed by stamping sheet metal. The latch sled is slidably mounted on the faceplate by way of integral longitudinal channels which engage tracks which are an integral part of the faceplate. Both tracks and channels are formed during the stamping process. An actuator arm slidably operates the latch sled between engaged and disengaged positions. A biasing spring is provided for biasing the actuator arm to either the engaged or disengaged position. A forked tongue having a slot for guiding the biasing spring extends upwardly from the latch sled and is also formed during the stamping process. The slot which is formed during the stamping of the forked tongue is notched to provide securing of the housing spring.

  • Patent number: 4209876
    Abstract: A floor mountable door stop having a quarter-spherical backstop portion with a substantially vertical backstop face, an integral tongue mounting portion extending away from the bottom of the backstop face, and an integral anchor member extending downwardly from the bottom end of the backstop portion, wherein the door stop is manufactured by stamping thin sheet metal. In a preferred embodiment, the anchor member is semi-circular so as to mate with a semi-circular or C-shaped slot in the floor.

  • Patent number: 4159838
    Abstract: A door latch bolt locking device for use with a latch bolt having a transverse groove or kerf in its top surface and which will positively prevent the withdrawal of the latch bolt. The device comprises a slideable member adapted to be substantially flush with the intersecting edge surface of the door and the inner surface of the door. The slideable member will have a first portion which will be substantially flush with the inner surface of the door and an integral tongue portion at a right angle to the flat portion and adapted to be substantially flush with the edge surface of the door. The locking device is also provided with means for allowing the slideable member to be moved through a limited vertical distance in a substantially flush relationship with the door surfaces so that the tongue member can move into and out of the kerf provided in the latch bolt to thereby lock the door.

  • Patent number: 4003593
    Abstract: A push door-latch opener suitable for hospital rooms including a door mounting plate, a horizontal pivoting rod attached to the plate, a vertical pivoting rod attached to said plate and located above the horizontal rod, a horizontal bell crank pivoted about said vertical rod and having a first arm projecting into the plane of the door and a second arm being substantially parallel to the plane of the door, a torsion spring for biasing said bell crank in a direction so that the second arm is biased in the direction of the first arm, and a downwardly-directed push handle pivoted about said horizontal rod and being biased to a first out position and being adapted to be pushed to a second in position, the push handle having above the horizontal rod an upwardly-directed projection which engages the inner surface of the second arm of the bell crank so that when the push handle is pushed, the projection turns the second arm away from the door and simultaneously turns the first arm, thereby operating a latching mechan
