Abstract:
A vehicle sliding door opening/closing control device comprises a control unit for outputting a standby signal and shifting into a standby mode when for a predetermined time there has been no user-operation input for causing a vehicle sliding door driven by a motor to be open/close-driven and shifting into an operating mode and performing control of the motor when there has been a user-operation input and a switch unit for shorting power input terminals of the motor on the basis of the standby signal. When there has been no user-operation input for causing the sliding door to be open/close-driven for a predetermined time, by shifting into a standby mode the power consumption of the control unit can be kept small and as a result it is possible to suppress the battery power consumption of the control unit. Also, in the standby mode, by shorting the power input terminals of the motor it is possible to keep the motor in a locked state and thereby apply braking to the sliding door. Therefore, when the vehicle has been stopped or parked on sloping ground such as an upward slope or a downward slope, it is possible to prevent the sliding door from starting to move under its own weight when it is half-open.
Abstract:
A device for closing a sliding screen door is disclosed. The inventive device includes a housing mountable proximal to a sliding screen door. A retractable cable resiliently extends from the housing and couples with the sliding screen door to effect closing of the door subsequent to opening thereof.
Abstract:
A closing control and opening free assembly for a hinge connection is mounted within various articles of furniture or implements. The assembly has a mounting element having a circular hole, a pivot member or rotor disk connected therewith, the circumference of which gets into contact with the inside surface of the circular hole, one or more pair of spring and roller positioned in each of recess formed on the periphery of the circular hole or the pivot member, and a brake component. When opening a rotatable section upward, the pivot can rotate together with the brake component, and thus it is possible to open freely the rotatable section. When closing the rotatable section downward, the pivot can not rotate with the brake component. Consequently, the rotatable section is rested at a desired turning position.
Abstract:
A fluid free damper, comprising a spindle member; housing means mounted for relative eccentric rotation with respect to the spindle member; and engagement means interposed between the spindle member and the housing means for rotation along with one of the housing means and the spindle member with respect to the other one of the housing means and the spindle member so as to be deformably compressed between the spindle member and the housing means and thereby generate a resistive damping force between the housing means and the spindle member in response to the eccentric rotation of the one of the housing means and spindle member with respect to the other one of the housing means and the spindle member.
Abstract:
A brake and clutch assembly mounted on an electric motor's drive shaft comprises, in succession and outwardly from the motor, a brake pad, a drive disk, a clutch plate, a pulley, a compression spring and an end cap. The drive disk includes a sleeve with the clutch plate and the pulley being slidably mounted thereon. A pin extending diametrically through the shaft lies in a diametrical V-shaped recess defined in the drive disk. The spring biases the pulley, clutch plate and disk drive towards the brake pad thereby frictionally retaining the drive disk thereagainst when the motor is not operating and preventing the components from rotating. When the motor is started, the pin climbs out of the bottom of the recess by pushing the drive disk against the spring's force thereby axially displacing slightly the disk drive away from the brake pad such that the pin rotates the drive disk which frictionally drives the clutch plate and the pulley. Resistance applied against the rotation of the pulley causes the clutch plate to slip thereby allowing the pulley to stop while the clutch plate, the drive disk and the motor shaft continue to rotate, thus preventing damage to the motor. The friction forces between the clutch plate and the pulley are insufficient to stop the clutch plate and thus the drive disk and the motor shaft if the pulley is forced to stop rotating.
Abstract:
The present invention is provided with a mechanism for controlling the opening and closing of a door comprising a speed reduction means for reducing a rotational speed. A high speed shaft is connected to the speed reduction means and is connectable to a means for rotating the input shaft, and a low speed output shaft is connected to the speed reduction means. A governor is mounted on the input shaft for limiting the rotational speed thereof, to also regulate the rotational speed of the output shaft. A brake is provided for preventing rotation of the output shaft, and a self-closing mechanism is operatively connected to the door. The self-closing mechanism is adapted for storing energy when the door is opened to an open position, and a connecting means operatively connects the output shaft to the self-closing mechanism. A releasing means is provided for releasing the brake to permit rotation of the output shaft under the urging of the self-closing mechanism whereby the self-closing mechanism releases the energy stored therein so as to close the door to a closed position when the brake is released by the releasing means.
Abstract:
An electrically powered pet door assembly for use in a home or building. Each assembly includes a frame which is secured to an exterior surface of a building, a panel slidably mounted within parallel tracks of the frame, a rotatable and translational drive assembly for vertically raising the panel, a centrifugal brake for controlling the speed of the vertical opening or closing of the panel and a treadle for activating the rotational and translational drive assembly.
Abstract:
A mounting device 10 for the wings 2 of windows, doors, etc., which consists of a bearing rail 11 to be secured in the groove 1' on the frame side and a holding rail 12 which also fits into the groove on the wing side, and of two guides 6 and 7 Each of the guides 6 and 7 is connected on one side to the bearing rail 11 and on the other to the holding rail 12 such that it can move at least in a pivoting motion and is non-detachable.Simple hinging and unhinging of the wing 2 relative to the fixed frame 1 is achieved by the fact that at least the bearing rail 11 can be connected using a plug-type connection to the bases 13 and 14 mounted on the periphery of the groove surface 1' of the fixed frame 1 in a detachable-interlocking manner 24,25 and 26, 27 and can be secured against these bases 13 and 14 in contact position by means of a latch 26, 27".
Abstract:
A friction stay includes a track 10 for attachment to a window frame. The track 10 has a nose portion 14 with a curved inner surface which receives the nose portion 28 of a bar 24. Bar 24 is pivotally attached to the track 10, by a link 16 joined to the bar 24 at rivet 25 and to track 10 at rivet 17. The bar 24 is also attached to a slider 15, engaged in track 10, by a link 21 pivoted on rivets 22, 23. A brace 18 extends from link 16 to slider 15 and is attached by rivets 19, 20. Optionally an extra link 26 may be included. To provide additional strength, in accordance with this invention, a link 31 is provided, pivoted to link 16 at 32 and to a second slider 35 to 34.
