    Abstract: A counteraction system for a sectional door includes a counterweight system that helps counterbalance the weight of the door and helps hold the door in place when the door is fully open. The counterweight system comprises a suspended string of individual deadweights. As the door opens, the weights sequentially lower onto the floor, in a stacked arrangement, one atop the other. Thus, the hanging weight of the counterweight system decreases as the door opens. To avoid having the counterweight system slam the door open against a hard stop, the counteraction system also includes a brake system that helps bring the door to a smooth stop at the door's fully open position. In some embodiments, the brake system includes a cable that traverses the direction that the door travels. As the door approaches its open position, a protrusion on the door catches the cable, which deflects to decelerate the door.

    Abstract: An overhead door is provided with a pair of stays and respective stay holding tension springs arranged such that, when the door is closed, they are expanded only less than twice of their length so that they are not subjected to excessive loads and hence can have a prolong service life. Each of the stays is rotatably fitted to the inner surface of a corresponding lateral wall of a cabinet main body by way of a rotary shaft and have its front end pivotably secured to the door at a position close to the lower edge of the door. A pair of slide rail assemblies, each comprising an outer rail and an inner rail, are arranged such that the outer rails are fitted longitudinally in parallel with each other on the inner surface of the door and the upper end of each of the inner rails is pivotably secured to the front edge of the roof board of the cabinet main body. Each of the stay holding tension springs are arranged so that each of them is hooked at an end to a position located upward and forward relative to the corresponding rotary shaft on the inner surface of the related lateral wall of the cabinet main body and at the opposite end to a middle point of the corresponding stay.

    Abstract: A sectional gate assembly to move a sectional gate between an open position and a closed position by an upper and lower closing element. The upper closing element is flexibly connected with the lower closing element, and both the upper and lower closing elements each have a first and a second opposite side and one or more guides which are arranged on each of the first and second opposite sides of the closing elements. The sectional gate assembly includes a first and a second single track guide rail. The first and second guide rails each have a vertical section and a horizontal section connected with a curved portion. One or more of the guides on the upper and lower closing elements are adapted to move within the guide rail. A weight-counterbalancer is included in the sectional gate assembly. The weight-counterbalancer has a traction mechanism which engages at a first end on one of the upper and/or lower said closing elements, and at a second end on an energy accumulator which allows the lower closing element to move into the horizontal section of the rail guides. The weight-counterbalancer also includes a deflection roller for the traction mechanism which is arranged beneath the horizontal section of the rail guides so that the weight-counterbalancer exerts, by way of the traction mechanism, a pulling force that acts generally horizontally on the lower closing element in the gate open position. The pulling force acts generally vertically on the lower closing element in the gate closed position. The sectional gate assembly further includes a mechanism to swivel an upper edge of the upper closing element out of alignment with the guide rails in the closed position. The mechanism includes a pivoting lever attached to the upper closing element and has an arrangement to drive the upper closing element from a first position in the gate open position into a second position in the gate closed position and back to the first position.

    Abstract: An oven door hinge having stable positions in closed, broil and open positions of the door includes an elongated support member which extends along the side of the door, and a hanger with an elongated arm portion which removably seats in a recess adjacent the lower side of the oven cavity. The hanger also has a depending hinge portion which is pivotably supported on the support member adjacent its lower end. A translation member has its lower portion pivoted to the hanger arm portion, and an upper portion which is disposed within the support member. A spring is connected between the upper portion of the translation member and the upper end portion of the support member so that opening of the door displaces the translation member relative to the support member and hanger and tensions the spring. The support member and translation member have cooperating positioning elements to bias the door into its closed position and to hold the door in its broil position.

    Abstract: A one piece lubricious plastic cable guide and door stop for guiding a tensile stressed flexible cable-like member through a work piece aperture and then angularly behind the workpiece. The guide is self-retained in said aperture and includes a latch member for temporarily restraining the cable-like member against the tensile stress inducing device during assembly of the opposite end of the cable-like member with a hinged closure member. It is applicable to devices such as a horizontally hinged dryer door that is spring biased by a pair of said cable-like members and one or more coil springs.

    Abstract: A motor driven winding mechanism suitable for a vehicle panel or the like, said window being movable by means of a raising and lowering mechanism (41) having an operating shaft (50) thereon which is rotatable to effect raising and lowering of the window, includes a reduction gear unit (10-30) drivingly coupled to the motor and to be mounted on the operating shaft for rotating that shaft, and sensing means (52-62; 72-80) for sensing rotation of the gear unit about that shaft due to reactive torque produced in the gear unit during operation and controlling operation of the motor in accordance therewith, for example, by de-energizing or reversing the motor upon a predetermined rotation being sensed. The sensing means senses predetermined displacement of the reduction gear unit around the operating shaft axis against the action of a spring (60, 80) resulting from reactive torque produced therein.
