Abstract:
A power boost assembly is disclosed that can be used with a door actuator, such as a door closer. The power boost assembly is structured to store an energy during a first movement of a door and release the stored energy during a second movement of the door. In one form the power boost assembly can be structured as a module that can be added to an existing door and door closer installation. In one form the power boost assembly is used to increase a closing force imparted to a door to ensure a latching event.
Abstract:
A side sliding door apparatus for a vehicle includes one of two sliding doors driven by an actuator, and the other moves in conjunction with the one sliding door via a direction converting mechanism. When the sliding door is in a closed condition, a latch rod is inserted into a lock hole to lock the sliding doors in the closed condition. A roller is pushed up on a cam surface when the sliding doors are opened, which releases the locking. An upper level surface of the cam surface forms an inclined surface with a downward gradient, which prevents the roller from unexpectedly going beyond the starting end of the upper level surface and dropping due to vibration or the like being applied to the slider in the unlocked condition, and prevents the locking with the locking mechanism in response to the next sliding door closing command.
Abstract:
An auto-closing device has a base, a cylinder, a slider, a spring and an adjusting device. The adjusting device is connected to an end of the spring opposite to the slider and has an adjusting frame and an adjusting bolt. The adjusting frame has a first end connected securely to the spring and a second end provided with a threaded hole. The adjusting bolt is mounted rotatably on the base and is screwed into the threaded hole in the adjusting frame. Accordingly, when the adjusting bolt is rotated, the adjusting frame is moved relative to the body so that the pulling force provided by the spring is adjusted to fit with different door panels with different weights.
Abstract:
Provided is a door opening and closing system capable of returning to a return state where a catch and a retractable arm are engaged with each other even if the retractable arm is closed completely as a result of incorrect usage such as a prank. A catch has a catch base which is mounted on either one of the door and a frame and a catch shaft which is installed in the catch base slidable in an axial direction and engaged with a retractable arm. At a tip end of the catch shaft, a small-diameter part is provided as a step part. The step part of the catch shaft and the retractable arm are engaged with each other in a state where the retractable arm is further rotated in the closing direction after a main body part of the catch shaft and the retractable arm are engaged with each other.
Abstract:
The hinge (1) for furniture comprises at least one deceleration device attached to the outside of the hinge box (4), an actuating lever (12) for the deceleration device, supported in oscillating fashion in the hinge box (4), and elastic return means to bring the actuating lever (12) back to an initial position, the deceleration device comprising a housing body (15) which extends peripherally along a side wall (9) of the box (4) and has means for fixing it to the side wall (9), the elastic return means being located on the housing body (15) outside the box (4) and providing at least one elastic arm (16) which protrudes into the inside of the box (4) through an aperture (17) in the side wall (9) of the box (4) to connect operatively with the actuating lever (12).
Abstract:
Provided is a retracting device in which dampers have improved durability and strokes of operation of the dampers are not reduced. A first slider 14-1 for assisting closing, a second slider 14-2 for assisting opening, and a damper base 22 are provided in an elongating base 12 to be slidable in a longitudinal direction of the base 12. The damper base 22 is disposed between the first slider 14-1 and the second slider 14-2. A first damper 24 is provided over between the first slider 14-1 and the damper base 22 and a second damper 25 is provided over between the second slider 14-2 and the damper base 22.
Abstract:
A sliding door device has a first pin body provided, at a floor surface; a guide member provided at the door and having a guide groove in which the first pin body fits when the door is closed; and a second pin body that is provided on the floor surface and can be fit in a door groove formed at the door bottom. When the closed door slides in an opening direction and toward the back side of the wall surface, the guide member moves relatively along the first pin body while the first pin body is fit in the guide groove of the guide member. When the door slides further in the opening direction, the second pin body gets in the door groove of the door, and the door slides along the second pin body while the second pin body is fit in the sliding groove of the door.
Abstract:
An engine hood for a construction machine is configured to be pivoted in a vehicle body back-and-forth direction about a hinge attached as a pivot center to a longitudinal side part of a counterweight. The engine hood includes an engine hood main body, a first operating force applying unit and a second operating force applying unit. The engine hood main body is attached to a vehicle body of the construction machine in a pivotably openable/closable state. The first operating force applying unit is configured to apply force in a direction of opening the engine hood main body until the engine hood main body reaches a vicinity of a predetermined opening angle. The second operating force applying unit is configured to apply force in a direction of closing the engine hood main body when the engine hood main body is pivoted at the predetermined opening angle or greater.
Abstract:
To reduce stresses during closing of a manually closable body component, e.g. a door, a control device and a method of controlling closing movement in which, during the closing movement, from an opened position, the body component passes through first movement range in which the body component is moved towards the closed position without any action by a control member, and, thereafter, the body component passes through a second movement range in which the closing movement is varied by the action of the control member that residual kinetic energy of the body component does not exceed a predetermined limit value after passing through the second movement range, irrespective of the initial speed. The residual kinetic energy is not sufficient to close the body component automatically, so it is automatically drawn in a third movement range until a pre catch or main catch of a lock is reached.
Abstract:
An object is to provide a storage in which a door can be attached using a similar hinge without any trouble even at a time when the door is rotated in reverse and attached, the storage includes a main body; a pair of upper and lower hinges attached to the main body; and a door having one side rotatably supported by both the hinges to openably close an opening, at least one of the hinges has two attachment portions which cross each other at right angles in a corner and which are attached to the main body, and two pivot support portions raised from both the attachment portions and provided with a rotary shaft rotatably supporting the door, and both the attachment portions and both the pivot support portions have a shape which is symmetric with respect to a line passing through the corner and forming an angle of 45° with respect to both the attachment portions.
