An inverted constant force window balance system has a carrier assembly including a housing with a first and a second housing wall, a coil spring with a free end, and a shoe assembly slidably coupled to the housing. The shoe assembly includes a first and a second shoe face. The housing slides between a first and a second position relative to the shoe assembly. When in the first position, the first and second housing walls are substantially non-coplanar with the first shoe face, and when in the second position, the first housing wall is substantially coplanar with the first shoe face and substantially non-coplanar with the second shoe face. The shoe assembly receives a pivot bar from a window sash and extends a brake upon rotation thereof. The balance system also includes a mounting bracket releasably coupled to the housing and coupled to the free end of the coil spring.

The present invention relates to a door hinge system (10) for a pivoting door (30) of a domestic appliance (20), in particular for a pivoting oven door (30) of a cooking oven (20). The door hinge system (10) comprises a stationary hinge part (12) in arranged or arrangeable at or in a chassis of the domestic appliance (20). The door hinge system (10) comprises a pivoting hinge part (14) connected or connectable to the door (30). The door hinge system (10) comprises a driving device (16, 18, 22, 24) for driving the pivoting hinge part (14). The driving device includes at least one motor (16) coupleable to and decoupleable from the pivoting hinge part (14). The driving device (16, 18, 22, 24) is automatically controllable. The pivoting hinge part (14) is manually pivotable, if the motor (16) is decoupled from the pivoting hinge part (14).

This application provides a vertical sliding window, including horizontal frame side edges, vertical frame side edges, and an opening sash, wherein the opening sash slides up and down along a guide rail on the vertical frame side edge. In addition, the vertical sliding window further includes a balance weight device and a balance weight traction cable. The balance weight device includes an enclosure, a rotating shaft partially disposed within the enclosure, a spiral spring whose two ends are respectively fixedly connected to an inner wall of the enclosure and the rotating shaft, and a cone pulley fixedly connected to the rotating shaft, wherein a tapered surface of the cone pulley is provided with a spiral groove. A lower end of the balance weight traction cable is fixedly connected to the opening sash, and an upper end thereof is fixedly connected to the cone pulley. When the opening sash moves from bottom to top, an elastic deformational force generated by the spiral spring enables the balance weight traction cable to be gradually wound into the spiral groove, and the elastic deformational force of the spiral spring is gradually reduced. Due to a mutual conversion between elastic potential energy of the spiral spring and gravitational potential energy of the opening sash, in the vertical sliding window provided in this application, an external acting force for dragging the opening sash to move up and down as well as energy consumption may be reduced.

A method of making a composite pipe has the steps of (a) providing one or more sources of composite tape, the composite tape being formed of reinforcing fibres embedded in a thermoplastic matrix; (b) helically winding the composite tape(s) around a cylinder under the application of heat to form a pipe comprising fused, concentric layers of adjacently positioned, helically-wound composite tape; (c) scanning a region where edges of wound composite tape are expected to be, to generate scanning information; (d) controlling the gap between further adjacent windings by (1) using the scanning information to determine wound composite tape edge position(s), and (2) using the determined wound composite tape edge position(s) to adjust the winding process during winding; (e) repeating steps (c) and (d). The invention also relates to a corresponding apparatus for making a composite pipe.

A sliding golf cart windshield assembly includes a first elongated rail having a top end and a bottom end, and a second elongated rail spaced apart from the first elongated rail and having a top end and a bottom end. An upper windshield pane has a first longitudinal edge and an opposing second longitudinal edge, where the upper windshield pane is positioned between the first and second elongated rails. In addition, the assembly includes a first upper plate secured to the first longitudinal edge of the upper windshield pane and being slidable within the first elongated rail, a first lower hub coupled to the bottom end of the first elongated rail, and a first belt having a first end first end fixed to the top end of the first elongated rail and passes around the first lower hub to the second end that is fixed to the first upper plate.

The present disclosure is directed to overhead doors and overhead door operation. More specifically, the present disclosure relates to a direct drive counter balancing system for operating overhead doors. In some examples, the direct drive counter balancing system of the present disclosure is for overhead door systems used in segmented door arrangements for box trucks.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

The present invention is concerned with vertically sliding facade components. In order to improve operability and user comfort for vertically displaceable facade components, a weight compensation device (10) for vertically displaceable facade components comprises a spring element (12) for at least partial compensation of its own weight of a vertically displaceable facade component and a compensator (14). The spring element provides a spring force as a driving force (F.sub.AN) for lifting the vertically displaceable facade component. The spring element is movable between a compressed state (P.sub.K) and an expanded state (P.sub.E). The spring force has a decreasing value when moving from the compressed state to the expanded state. The compensator at least partially compensates for the decrease in the input force and provides an output force (F.sub.AB) that decreases less than the input force.

A furniture drive includes a carrier to be fixed a furniture carcass, an actuating arm for moving the movably-supported furniture part relative to the carrier, the actuating arm being pivotable about a first pivoting axis, and an interface for fixing a synchronization shaft, and configured to synchronize a pivotal movement of the actuating arm with a pivotal movement of an actuating arm of a further actuating drive. The interface includes a component pivotable about a second pivoting axis, the second pivoting axis being arranged laterally offset to the first pivoting axis of the actuating arm. The carrier has an upper side which, in a mounted condition of the furniture drive on the furniture carcass, faces towards a top panel of the furniture carcass, and the first pivoting axis has a larger perpendicular distance to the upper side than the second pivoting axis.
