Abstract: A keyless floor mounted door lock of this invention has a horizontal rectangular frame with a rectangular opening therein having first and second sides and opposite ends. A first downwardly extending bar is secured to one of the sides of the frame and a second downwardly extending bar extends parallel thereto in spaced relation. A pivotal surface is located on the under side of the frame at the ends of the slot which is created by the space between the first and second bars. A stop plate has a size slightly smaller than the opening in the frame and is slidably mounted in the slot when in a vertical position, and has opposite sides and opposite ends. Hinge elements are located on one of the sides of the stop plate adjacent the ends, and have a tang element extending longitudinally from each end for engagement with a pivotal surface on the bottom face of the frame.

Abstract: A retractable flush-mounted apparatus which is mounted in a floor or other flat mounting surface. The apparatus includes a housing with a flange plate which is mounted in an opening in the mounting surface. A retractable member is provided within the housing which alternates between a raise position and a lower position. By pressing downwardly on the top of the retractable member, a latching mechanism is released, allowing the spring biased retractable member to move to the raised position. The retractable member is lowered by applying a force sufficient to counteract the action of the spring and move the member into the housing, whereupon the latch mechanism re-engages the retractable member to retain it in the lower position. The apparatus can be adapted for use as a security door stop or as a pop-up utility outlet. When used as a security door stop, the risk of accidental lock-out is reduced through the use of a ratchet plate and camming surface.

Abstract: A door securing device including an upper housing member being mounted about a door knob rose. The upper housing member encasing a locking mechanism with a trigger. A lower housing member is mounted to a lower door portion and has a bottom opening. The lower housing member has a rear wall with a pair of sprocket frames projection therefrom. A cable guard with a cable is coupled with the trigger. The cable guard is coupled with the upper housing member and the lower housing member. A door stop mechanism is housed within the lower housing member. The door stop mechanism has a stop wedge with a top side having a track, and a bottom side with a stopper. The door stop mechanism has a first sprocket member and a second sprocket member that rotatably coupled between the pair of sprocket frames. The first member capable of engaging the track. Included is a chain for engaging the first and second sprocket members.

Abstract: A door stop wedge is mounted into a receptacle recessed in the floor inside an inwardly-opening door. A detent keeps the wedge normally in an inoperative position within the receptacle and releasable by downward foot pressure on a tab connected to the locking arm for such detent. The wedge is spring-loaded to pop up into operating position when the detent is released. Foot pressure on the back of the wedge will cause it to retract into the receptacle and the detent to spring back into locking position.

Abstract: A hatch securing mechanisms has a base attached to a hatchway and a hasp ached to a hatch lid. The base has an apertured retainer and a pinway element, the hasp being held between the retainer and pinway element during closure of the lid. A latch pin translatable in the pinway element has an angled tip which slides against a bevelled surface of the hasp to force the hasp into tighter, locked engagement with the base. The latch pin has a helical groove segment about the pin's axis, and a stud fixed to the pinway element engages the groove segment. The interaction of the stud and groove segment effects translation of the latch pin when the pin is manually rotated. The action of the latch pin also compresses an elastically deformable seal between the door and door frame so that the seal is increasingly effective against explosive blast pressures. The invention includes a lock mechanism for keeping the latch pin in a hasp retaining position unless the pin is manually moved.

Abstract: The access door of a chamber housing opening is secured releasably in closed position by a latching mechanism provided on each of the four edges of the door. Each latching mechanism includes a plurality of spaced apart wedges projecting outwardly from the edge of the door for releasable registry with a plurality of spaced apart wedges on a wedge member mounted on the chamber housing for movement by an hydraulic cylinder between a door opening position in which the wedges on the door register with spaces between the wedges on the wedge member, and a door latching position in which the wedges on the wedge member are moved by the hydraulic cylinder into sliding, wedging engagement with the wedges on the door, whereby to draw the door into sealing engagement with the chamber housing adjacent the periphery of the opening in the housing. An O-ring seal disposed about the periphery of the door is arranged to engage the chamber housing upon closure of the door, to seal the chamber for evacuation or pressurization.

Abstract: A fastening apparatus operable to secure a pair of work objects to each other and wherein one of the work objects mounts an engagement member, the fastening apparatus having a mount adapted for attachment on the other of said work objects in substantially a predetermined position; and a grasping assembly borne by the mount and operable to expand upon movement of said engagement member therewithin and subsequently to contract for engagement with said engagement member to interlock the work objects.

Abstract: A wedge security device to be positioned on a floor at the inside bottom edge of an inwardly opening door includes a wedge shape member including an upper and lower surface leading at a front acute angle such that the bottom edge of the door will ride up on the upper surface of the wedge with a rounded surface extension allowing the wedge to rock backwardly when the edge of the door engages the wedge, a resilient compressible pad to facilitate wedging of the member under the door and a rubber appendages pad on the bottom of the wedge shape to prevent sliding along the floor surface with a pair of guide member with slots to allow the door to move toward and up on the wedge shape, but prevent its movement backwardly away from engagement once it has been wedged into position.

Abstract: Disclosed is a door security device for mounting adjacent a door comprising base plate means adapted to be secured to the frame of a door adjacent a floor. Wedge means is pivotally associated with the base plate means through two hinge means which hinge means are planar and perpendicularly oriented with respect to each other such that the wedge means may be pivoted between an operative position for wedging action with a partially open door and a stored position adjacent the door opening and substantially off the floor.

Abstract: A tongue or other insert part of a securing member for accessories such as ear muffs, is held in place in an attachment slit at the rim of a protective helmet by a substantially wedge-shaped locking adapter provided with barbs or saw-teeth engaging in recesses in the tongue of the securing member. The locking adaptor, together with tongue of the securing member, substantially fills the attachment slit, thus wedging the securing member in position. The barbs or saw-teeth may be formed on the tongue of the securing member and complementary recesses formed in the wedge-shaped adaptor.

Abstract: A security device characterized by a base which attaches to the top of an upper track of a sliding door or window, a wedging member having an end pivotally attached to the base, a spring biasing the wedging member towards the base, and a propping member having an end pivotally attached to the base and movable, under the influence of gravity, to an overcenter position to retain the wedging member in an open, wedging position. When closed, the device fits within the space between the top of the sliding door or window and the top of the upper track of the door or window, and when open the device prevents or limits the opening of the sliding door or window.
