  • Patent number: 5820177
    Abstract: A mortise lock assembly is provided for mounting in a door opposite a strike plate on a door jamb. The assembly includes an automatic deadbolt feature with a bolt retractor arm that directly contacts and applies inward retraction pressure to a latch bolt and a deadbolt in response to bolt retractor hub rotation to retract the latch bolt and the deadbolt. Two deadbolt stops engage two housing stops when the deadbolt reaches the deadbolt extended position and restrain the deadbolt against further outward movement. Coil extension springs continuously bias the deadbolt and the latch bolt against retraction. A dead lock blocker releasably holds the deadbolt in the deadbolt extended position. The bolt retractor arm is additionally engageable with the blocker to release the blocker in response to bolt retractor hub rotation. A trigger releasably engages and retains the deadbolt in the deadbolt retracted position.

  • Patent number: 5820174
    Abstract: A lockable, slammable paddle operated latch assembly for use as a latching and locking mechanism on a door or panel of an enclosure or compartment has a paddle handle pivotally mounted on a pin transversely mounted through side walls of a recessed draw of a mounting pan and attached at one end to an orthogonal trip/lock member on the interior of the pan adjacent the draw. One extension of the trip/lock member is positioned underneath the locking arm of a key cylinder when the paddle is fully recessed and the key is in the locked position. Another extension of the trip/lock member contacts the latch which is pivotally mounted on the interior of the pan draw. A torsion spring about the latch mounting shank biases the latch into the latched position, but allows the latch to be deflected for engagement with a striker with the trip/lock member locked or unlocked, so that the latch can be slammed shut even when locked. A latch guide can also be mounted on the latch mounting shank.

  • Patent number: 5819567
    Abstract: A novel lock system utilizes a cylinder lock and a companion key with a projection extending from one side thereof to improve security. The cylinder lock comprises a shell, a core which is rotatably mounted within the shell and a plurality of pin tumbler stacks normally prevent movement between the shell member and the core. Shear lines are defined between the shell and the core, and also within each tumbler stack. The core also includes an outer surface, a longitudinal keyway and a cut-out which is normally offset from, but alignable with, at least one of the tumbler stacks. A plate member is disposed within the cut-out for movement between a first position, wherein the plate member acts as an extension of the core surface to prevent a tumbler stack from entering the cut-out and a second position, wherein the plate member does not prevent a tumbler stack from entering the cut-out.

  • Patent number: 5816174
    Abstract: Automated attendant terminals and a mounting system for such terminals. Each attendant terminal is substantially L-shaped and comprises a housing formed by front, opposing side, rear, and first and second contact surfaces. The first and second contact surfaces form the recessed portion of the L-shape. When used in connection with the mounting system of the present invention, the first contact surfaces and/or the second contact surfaces of each terminal contacts the surfaces of the support mechanism (such as a pole) to result in a "back-to-back" orientation of the terminals. The support mechanism includes opposing surfaces for such engagement with the contact surfaces of the terminals. The mounting system also includes an attachment mechanism which connects the terminals to the poles in this orientation. The attachment mechanism is only accessible through the interior of the housings of the terminals to thereby provide a secure island automated attendant terminal system.

  • Patent number: 5815864
    Abstract: An air pressurization and control system for a low air loss air floatation mattress or cushion is disclosed. The control system controls air supplied to the air floatation mattress within a range of pressures and flowrates so as to inflate all of the cells of the mattress and to maintain a flow of air to all of the cells over an extended period of time while maintaining all of the cells at a desired level of inflation for the air floatation support of the patient without any of the cells exerting decubitus pressures above the maximum desired decubitus pressure and so as to prevent collapse of any of the cells. A sensor is provided for sensing the pressure of the air within the common supply.

  • Patent number: 5813066
    Abstract: A baby rest for placement upon a support surface employs a generally C-shaped inflatable tube member surrounded by padding, the combination of the tube member and padding encased in a generally circular outer fabric cover. The outer cover substantially traverses the center area of the C-shaped tube, thereby creating a thinly padded, central rest area on which an infant may lie. The tube member can be inflated to varying degrees, such that the tube member and the surrounding padding create a peripheral guard around the center rest area of sufficient height to prevent an infant from rolling out of the proportionally smaller rest area.

  • Patent number: 5810405
    Abstract: A latching mechanism for a swinging door pivotally mounted on for movement about a first axis between fully open and closed positions includes a support column pivotally mounted for rotation about a second axis parallel to the first axis. One end of the support column is provided with a support block for supporting the door in the open position, and the other end of the support column is provided with a latching bar for securing the support column in a first position where the support block underlies an edge of the door in the open position. A cam surface is provided on the support column, engagable by the door as the door moves from the closed to the open position to rotate the support column and the support block to a position which permits the door to move to a fully open position without interference from the support column or the support block.

  • Patent number: 5802638
    Abstract: A rest portion is used to support a load at an adjustable height relative to a base which is connected to the rest portion by a pivotal linkage. A hydraulic ram coupled to a gas spring cylinder applies a spring force between the linkage and the base, the geometry of the linkage and ram being such that the upward component of spring force is invariant with respect to height adjustment. A control valve allows the ram to be locked at a selected height and the spring force provided by the gas spring is adjustable by movement of a second piston within the gas spring cylinder to vary the available volume of gas. A hydraulic pump is used to supply hydraulic fluid to the cylinder for adjusting movement of the second cylinder. The apparatus is suited for use in a chair-bed enabling a patient to be supported at an adjustable height during medical treatment.

  • Patent number: 5795119
    Abstract: An adjustable lock nut comprising a one-piece annular body having an internally threaded axial bore extending between and faces of the body and a circumferential outer face. The body has a narrow annular internal groove that opens intermediate the ends of the axial bore and extends generally radially outwardly from the axial bore. A set of radial bores extend into the body at circumferentially spaced locations with their axes disposed in a plane normal to the body axis and bisecting the internal groove and the radial bores each include an internally threaded outer end portion and a threadless conical inner end portion, configured to form semi-conical recesses in the body at opposite sides of the internal groove adjacent the internally threaded axial bore. An externally threaded screw in the outer end portion of each radial bore actuates a wedge that engages the semi-conical recesses to apply separating forces thereto.

  • Patent number: 5794990
    Abstract: A child-proof safety latch for a swimming pool safety barrier, or other stretched-panel fence, includes a threaded rod having an expandable nut, such as a toggle-wing nut, that can move to and fro along the rod between a movable stop and a fixed stop adjacent an end of the rod that is distal from a first fence pole to which the rod is permanently affixed. To fasten two adjacent fence panels together, an operator collapses the expandable nut and inserts it through an eyelet attached to a second fence pole. The operator then expands the nut so as to capture the eyelet and turns the expandable nut so as to draw the two poles together.
