  • Patent number: 9523233
    Abstract: A swing type garage door has one or more of several features, including a door body rotationally connected to a door frame, the door body having one or more of: a trussing system having vertical and horizontal truss members, the horizontal members having openings through which the vertical members extend to distribute a load on the door body to the door frame in both a vertical and a horizontal direction; first and second sections hingedly connected with a hinge to allow ease in transport; a main door body section and a door load truss section hingedly connected at a bottom of the main door body to provide load trussing when the door is open; and at least one brace rotatably connected to the door body on an interior thereof and rotatable between a first bracing position and a second storage position to brace in high wind loading conditions.

  • Patent number: 8800208
    Abstract: A system and methods for controlling operation of hydraulic cylinders includes monitoring position of the cylinders relative to one another, and correction of misalignment of the cylinders should they become misaligned. Further, monitoring can be of a swing-type door operated using the cylinders, which can operate the door at different speeds. Further, as the door creeps open from a closed position or closed from an open position, correction is also made.

  • Patent number: 7029041
    Abstract: A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprises a latch arm assembly having a latch arm pivotally secured to a panel of the door and pivotable between a first, open position and a second, latched position. An activating mechanism is operably connected to the latch arm assembly by a connecting apparatus and actuates the latch arm between its first and second positions. A latch member is secured to the jamb in which the door is mounted and is arranged and constructed so that when the latch arm is moved into its second, closed position, the latch arm engages the latch member and exerts force upon the latch member in a direction substantially normal to the plane of the door so as to cause the door to contact the door frame over substantially its entire height.

  • Patent number: 6123482
    Abstract: An interruptible connector assembly adapted for the interlocking spatially of one tubular member with another object to be supported thereby, comprising: flexible clamping members adapted to be deformed into a U-shape and overlap any underlying planar surfaces; a single component, rigid support means, with each and having a proximal structurally identical arcuate component each end, such opposing arcuate surfaces adapted to nest a tubular member; a linear bore hole traversing of each of said gripping components; spherically faced cylindrical bushings, to slidingly engage the bore hole of its associated gripping component and each having at its shoulder contacting the adjacent support means; an elongate, assembly fastener means to slidingly traverse the aligned assembly via the component bore holes, being of a length sufficient to extend from one external side of the assembly to the other external side about the interlocked tubings.

  • Patent number: 5873591
    Abstract: A pair of upwardly projecting, readily displaceable, push-up handles which are selectively mountable on the lateral bars of a wheelchair framework. The handle mounting means for each side includes a tubular member that is fixed between the upper and lower rigid frame members of the wheelchair via a pair of dual U-ring interconnecting bracket means which secures the first tubular member to the frame members in a variable inclined position mode. A second tubular member of an outer diameter somewhat reduced and is adapted at its one longitudinal end to engage telescopically the open upper longitudinal end of the first member. At the upper longitudinal end of the second member is optionally located, a replaceable resilient gripping means.

  • Patent number: 5797697
    Abstract: An interruptible connector assembly adapted for the interlocking spatially of one tubular member with another object to be supported thereby, comprising: flexible clamp band adapted to be deformed into a U-shape and overlap any underlying planar surfaces; a two-component, rigid support means, with each structurally identical component, and having an at least partially arcuate proximal one end, such opposing arcuate surfaces adapted to nest a tubular member; a linear bore hole traversing of each of said clamping components; spherically faced cylindrical bushings, to slidingly engage the bore hole of its associated clamping component and each having at its shoulder contacting the adjacent support means; an elongate, assembly fastener means to slidingly traverse the aligned assembly via the component bore holes, being of a length sufficient to extend from one external side of the assembly to the other external side about the interlocked two tubings in a variable angle juxtaposition.

  • Patent number: 5540432
    Abstract: A portable device for non-stooping placement of golf balls and golf tees on site comprising an elongated tubular shaft with specially modified ends. The lower shaft end has a golf ball holding pincers and an adjacent dual tine, fork-like tee holding socket and tee retrieving device. The upper shaft end comprises a biased trigger mechanism cantilevered to actuate the upper end of an elongate solid rod disposed slideably within the shaft, and with the rod lower end adapted to carry a horizontal flange which reciprocates between the tee clamping position and a tee supporting position. The device is adapted for sequentially setting a tee in the desired ground and then placing the golf ball on the spotted tee while the golfer remains in a standing position throughout.

  • Patent number: 5498237
    Abstract: A squeeze-activated fluid applicator for human manipulation is provided to express the medicinal contents of rupturable capsules; the devise consisting of a shell-like, elongate member of uniform diameter adapted to receive slidingly at its proximal open end an elongate cylindrical member. A cantilever member is adapted to be pivotally mounted midway of the inner elongate member, with a vertical piston operatively connected to the cantilever proximal end, while a strong upward spring bias is provided on the cantilever distal end. A push rod located axially of the cylindrical member can be hand activated to dislodge a bias-arrest feature on the cantilever and to cause the piston to close into a proximal face capsule chamber of the cylindrical member, compressing and expressing the enclosed contents into an adjacent port.
