An overhead door system including a frame, a door leaf and a first hydraulic cylinder. The door leaf is pivotally mounted to the frame. The first hydraulic cylinder has a first cylinder end and a second cylinder end. The first cylinder end is operably attached to the frame. The second cylinder end is operably attached to the door leaf. The first hydraulic cylinder is capable of moving the door leaf between a closed configuration and an open configuration. At least one of the frame and the upper door panel has a slot formed therein. When the door leaf is in the closed configuration, the first hydraulic cylinder is substantially recessed in the slot.

The invention discloses a synchronous sliding mechanism, a side hidden door system, and a cabinet body with the side hidden door system. The synchronous sliding mechanism comprises a guide rail and a first connecting rod mechanism, wherein the first connecting rod mechanism comprises two sliding ends provided on the guide rail; and when the guide rail reciprocates in a horizontal axial direction, the two sliding ends are close to or far away from each other. Through connection between connecting rods and the guide rail, the guide rail may reciprocate stably and synchronously. The synchronous sliding mechanism is widely suitable for furniture such as door bodies, cabinet bodies and the like, and has an excellent effect.

A threshold sealing system for a door panel assembly includes a threshold biasing element and an anchor. The threshold biasing element including a base configured to attach to a floor surface and a biasing surface extending at an oblique angle relative to the base. The anchor is configured to secure the base of the threshold biasing element to the floor. The anchor and the threshold biasing element may be integrally formed and include the same materials. The oblique angle of the biasing surface ranges from 70 degrees to 80 degrees and has a height of at least 1.5 inches.

A window vent assist mechanism for use with a vent window operable in a closed position and in a vented position can include a first support configured to connect to a header of a window frame and a second support configured to connect to an upper rail of a window vent disposed in the window frame. The window vent assist mechanism also includes a biasing member disposed between the header of the window frame and the upper rail of the window vent and nearer to an inner side of the vent window and a center of gravity of the window vent. The biasing member is configured to exert a force to urge the window vent to move relative to the window frame to reduce an operating force required to move the window vent to the vented position.

Window hinge assemblies with energy control and methods of using the same are described herein. The hinge assemblies include a track assembly, a shoe slidably engaged in a shoe track of the track assembly, a sash arm configured for attachment to a rotating sash, the sash arm being pivotally attached to the shoe, and a connecting arm pivotally connected to both the track assembly and the sash arm. The track assembly includes a base extending along a track axis, a shoe track extending along the track axis, and one or more energy control structures associated with the sash arm.

A multi-bar linkage assembly for a pivotally mounted window sash and, more particularly, a high-capacity hinge assembly is disclosed. The hinge assembly is less susceptible to deflection during operation and may be used with and support window vents more than 100 in. tall and weighing more than 400 lbs. Notwithstanding the hinge assembly’s wide range of use, the hinge assembly stack height does not exceed the industry standard of 0.625 in. for conventional hinge assemblies incapable of use in heavy-duty applications. The hinge assembly may be used with standard form window frames without requiring redesigning or otherwise modifying the window frame’s standard form cross-section.

Cooking appliances described herein may include an oven and a cooktop disposed above the oven. The oven may have an oven cavity and an oven door configured to open and close the oven cavity by pivoting about a horizontal axis. A linear actuator may be coupled to the oven door and configured to reposition the oven door in a vertical direction. Using this apparatus, a user may be assisted by the vertically-repositionable oven door when lifting and lowering objects.

There is provided a hinge arm damper mechanism that reliably achieves a damper effect corresponding to a braking force of an elastic member. The hinge arm damper mechanism is configured to include a pinion gear, a pair of racks and, two sets of heavy load springs and, a pair of slide bars and, and a housing. The housing includes a box-shaped case and a plate-shaped cover. The case accommodates the pinion gear, the pair of racks and, the two sets of heavy load springs and, and the pair of slide bars and. A rotational torque applied to a hinge arm is transmitted to the racks and via a rotational motion of the pinion gear, and is converted into a linear motion of the racks and. The linear motion of the racks and is reliably braked by the respective springs and.
