摘要:
A safety device for a construction in which people are able to sit and with which movements can be executed, for example for an attraction for a fairground or an amusement park, comprises a base that can be fixed to the construction, a restraint that at one end is pivotably connected to the base and that can be moved between a lifted-up position such that the person is able to sit down in the construction or to leave the latter, and a safety position in which the person is secured in the construction, as well as locking means for locking the restraint in the safety position. The locking means have a locking component that is located at the end of the restraint that faces away from the end where the restraint is pivotably mounted.

A control apparatus controls movement of a lift arm (18) and tool (28) on a skid steer loader. Power actuators (22, 32) are coupled to a lift arm circuit (42) and a tool circuit (42) for moving the lift arm (18) and tool (28) along a path. A sensor (44) is coupled to the skid steer loader for sensing a desired parameter and providing a signal indicative of the desired parameter. A power interrupter (52, 54, 56) is coupled between the power actuators (22, 32) for the lift arm and tool and the sensor and interrupts power to the actuators (22, 32) based on the signal. A manually operable bypass mechanism (58) is coupled to the power interrupter and the power actuators (22, 32) and is used to bypass the power interrupter (52) to allow movement of the lift arm (18).

A sensor for a power machine includes a seat bar (21) which is movably coupled relative to a seat on the power machine. A magnet (112) and a Hall effect sensor (80) are coupled to the seat bar and to the power machine so that they are movable relative to one another based on movement of the seat bar. The seat bar is movable from a first position to a second position. The Hall effect sensor provides a position sensing signal indicating when the seat bar is in one of the first or second positions.

The invention relates to a retaining system having a retaining volume (24, 24') limited by a cladding (40, 40'), said retaining volume being enlargeable from a storage position (A) to a retaining position (R) in which the retaining volume (24, 24') serves at least indirectly to retain a person (14, 66), an object, or the like, wherein a mechanical enlarging unit (26, 26') is provided, by means of which the retaining volume (24, 24') can be adjusted into the retaining position (R).

An operator restraint bar (20) for a working vehicle, specifically for a skid steer loader, is mounted on the rear wall of the cab (10) of the loader and is movable from a restraint position to a raised position with one end adjacent the roof of the cab. The restraint bar is mounted onto brackets (26, 28) that are self contained and include a spring for holding the bar in either its working position or its raised position by arranging the pivot points of the bar and the spring so that they go over center between the working and raised positions. A sensor is used at the pivot for indicating when the restraint bar has reached its working position.

An apparatus controls operation of a power machine which has a frame, a seat supported by the frame, wheels supporting the frame, a drive mechanism (66) for driving the wheels, a lift arm structure manipulated by power actuators (22, 32), and a power circuit (42) for controlling the actuators. A occupancy sensor (46) is coupled to the power machine for providing an occupancy signal indicative of occupancy in the seat. A traction lockout mechanism (58) locks the drive mechanism to preclude the drive mechanism from driving the wheels. A controller (44) is coupled to the occupancy sensor, the traction lockout device and a power lockout device (60) and controls the traction lockout device and the power lockout device based upon the input from the occupancy sensor. A display (62) is coupled to the controller for displaying the indicia indicative of an operational state based on a display output signal provided by the controller.
