Abstract:
PROBLEM TO BE SOLVED: To provide a device for swinging a flap or a door with a spring, which allows pre-stress on a torsion bar mechanism to be adjusted (in an ex-post manner) with ease and at low cost.SOLUTION: The device comprises a torsion bar mechanism 1 which includes torsion bars 1a, 1b, and 1c arranged in parallel and in a zigzag fashion and connected to each other non-rotatably, supports outer torsion bars structured as a shaft bearing torsion bar 1c and a lever torsion bar 1a onto a shaft bearing platform 4 of a follow-up link mechanism 3, connects the lever torsion bar 1a non-rotatably against a length variable lever 6 which is guided by a control curve 5 of the follow-up link mechanism 3, and engages the length variable lever with a connecting rod 7, which is translational motion capable, for rotating a hinge lever 9 which is attached to a flap or door 8. In the device, an adjusting device 2 is provided, which is connected non-rotatably against the shaft bearing torsion bar 1c and is fixable onto the shaft bearing platform 4.
Abstract:
PROBLEM TO BE SOLVED: To provide a brake device capable of coping with a rail large in height dimension and also capable of increasing a life. SOLUTION: This brake device installed on the rail 10 and braking a runner 20 guided by the rail comprises a base part 100 mounted on the upper surface of the rail 10 and a leaf spring 200 having a base end part 210 slidably mounted on the base part 100. The tip part 220 of the leaf spring 200 is a plate-like body opened at its tip and curved backward. The tip of the plate spring is energized and brought into contact with the runner to brake the runner 20. The base part 100 comprises a projected part 120 positioned on a moving road for the base end part 210 of the leaf spring 200 and over which the base end part can ride by slidable movement and a contact stop part 130 on which the opened end part of the tip end part of the leaf spring displaced by the energization and contact is allowed to abut.

Abstract:
A hinge including: a first leaf assembly accommodating a portion of a first panel having a first cut-out section, the first leaf assembly including a first insert component which is tight fittingly receivable within the first cut-out section; a second leaf assembly, hingedly coupled to the first leaf assembly, for accommodating a portion of a second panel having a second cut-out section; a spring operatively coupled to the first and second leaf assemblies to bias the hinge to move from an open position to a closed position; and a dampener to dampen movement of the hinge from the open position to the closed position, wherein said longitudinal dampener axis is disposed between and substantially parallel with planes defined by respective opposing faces of the first panel.
Abstract:
A device for automatic closing of a door, to be applied to a hidden hinge having two bodies articulated with each other by a pair of arms and adapted to be constrained to one of the two bodies and to be inserted, together with the body, into a cavity obtained in the leaf, includes a translating element to be engaged with an articulation arm of the hinge; an elastic member interposed between a first element associated with the translating element and a second element associated with the body of the hinge, and configured to be loaded during the opening of the leaf and to cause the automatic closing of the leaf by releasing the stored energy; and a system that varies the preloading of the elastic member and is configured to modify the distance between the first and the second elements, between which the elastic member is interposed.
Abstract:
An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. One end of the torsion spring is fixed to a spring tension trolley. The trolley translates within a trolley guide mounted to the building structure. The other end of the torsion spring is fixed to a shaft running through the torsion spring. This allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the “snake-like” or serpentine appearance from an improper fixed torsion spring length.
Abstract:
An actuator for moving a movable furniture part includes at least one movably mounted actuating member for moving the movable furniture part, a spring device for applying a force to the actuating member, and a setting device by which a force of the spring device that acts on the actuating member can be set. The setting device has a threaded portion and a screw nut mounted adjustably between two end positions, and the force of the spring device acting on the actuating member can be set by adjusting the screw nut along the threaded portion. At least one supporting element is provided which relieves the screw nut in at least one of the two end positions of the force of the spring device.
