Abstract:
A portable door guard used to secure the door at the hinge, particularly the wings of the hinge. The portable door guard comprises a retractable, non-permanently fixed device that can be secured around the hinge of the door from the inside to prohibit the door to open more than a gap. The portable door guard includes a center area designed to grip the hinge to limit the swinging movement of the hinge and adjusting means to configure the size of the gap.
Abstract:
A door operator for moving a door includes a motor for moving the door between opened and closed positions, an operator for controlling the operation of the motor, and a switch, such as a wired wall station or a remote transmitter, for enabling the operator to control operation of the motor. Pushing and releasing the switch results in the operator allowing the motor to apply a normal range of torque values, and wherein pushing and holding the switch results in the operator allowing the motor to apply a broader-than-normal range of torque values. An external safety device coupled to the operator may be used with the operator. If the external safety device is enabled and the door is closing, the motor allows application of a higher-than-normal range of torque values. The door operator may also take corrective action if excessive door speed is detected. But, this corrective action can be overridden if the switch is held closed for a predetermined time.

PROBLEM TO BE SOLVED: To provide a hinged door device which is designed to draw a hinged door while braking the door from the start of closing to keep the door completely closed, when the hinged door is closed from a bit opened state. SOLUTION: A vertical frame 3 at the doorway 2 of a building is provided with a hinged door 1 with its one side rotatably supported with a hinge 4 around the vertical axial core, a magnet 9 with its tip face opposed to a magnetic plate 12 provided on the inner face side of the vertical frame 3 is provided and a damping mini-damper 14 opposed to the inner face side of the vertical frame 3, are provided on one side of the hinged door 1, wherein the tip of the operation pin 14a of the mini-damper 14 abuts on the inner face side of the vertical frame 3, applying brake on the hinged door 1 on closing from the start of closing of the hinged door 1 through the attraction of the magnetic plate 12 of the magnet 9.

Abstract:
A heavy duty full energy, encoder driven non-handed electric door operator for industrial and commercial use a motor and an encoder configured to receive an external set of predetermined instructions. A motor mounting bracket connects the motor to a multi-layer housing. A controller is in electronic communications with the encoder and transmits external sets of predetermined instructions. Internally, the door operator contains a plurality of transfer shaft assemblies in communication with each other and connected with the motor at one end and an output shaft at the other end. The output shaft terminates at each end in a nondetachable spline. A detachable mounting plate serves as a base. The door operator operates heavy swing doors external to a building where the swing doors are required to be open or remain open in strong wind conditions.
Abstract:
The unmanned vehicle for delivering an article, includes a housing portion for housing the article, the housing portion being provided with an openable and closable door, the door being closeable on a receiving surface of the article. Then, the unmanned vehicle identifies a direction of wind blown onto the unmanned vehicle; and on the basis of the identified direction of the wind, suppresses closing of the door, opened when the unmanned vehicle is stopped, due to an influence of the wind.
Abstract:
The invention is a sliding door (1) comprising a door leaf (2) and a guide (3) that allows the door leaf (2) to slide along the guide (3), wherein the sliding door (1) furthermore comprises first coupling means (4) and second coupling means (5, 5′) suited to couple the door leaf (2) with the guide (3). Said first coupling means (4) comprise one or more magnetic elements (6), in such a way as to exert a magnetic force (FM) between the first coupling means (4) and the second coupling means (5, 5′) so that the weight of the door leaf (2) is at least partially supported through the magnetic force (FM). The invention concerns also the use of one or more magnetic elements (6, 8, 8′, 8a) in a sliding door (1), a door kit comprising one or more magnetic elements (6, 8, 8′, 8a) and a guide (3), as well as a furnishing element like, for example, a wardrobe, a cupboard, a piece of office furniture, a fridge, a shower cubicle, a bathtub.
Abstract:
A system for reducing an effective weight of a horizontally sliding object is disclosed, wherein the system comprises an object such as a door or window retained in a track that allows substantially horizontal movement along a predetermined path. The door has an upper surface with a longitudinal cavity therealong, and a metallic channel is disposed within the longitudinal cavity, where the channel encloses a plurality of permanent magnets. The system also includes an elongate strip coinciding with said predetermined path and positioned adjacent an upper surface of the door. An adjustment mechanism is also provided for releasably adjusting the distance between the magnets and the elongate strip.
Abstract:
The invention relates to a method for controlling an actuator (1), particularly of a vehicle, wherein the actuator (1) is displaced in a predetermined position (4) by means of a drive (5). The force variable acting on the actuator (1) in the position (4) is determined, compared to a target value, and in case the target value is exceeded, the drive (5) is actuated for system relief. The invention further relates to an displacement system (8) for an actuator (1), particularly of a vehicle, comprising a drive (5) for displacing the actuator (1) and a control module (6), designed for the control of the drive (5) according to the method.
Abstract:
An actuator for moving a closure between an open and a closed position. The actuator having a first mode, where the closure is free to move with respect to a closure frame, and a second mode where the actuator resists movement between the closure and the closure frame.
