    Abstract: A passage barrier has first and second guide elements that cooperate to define a gate region, through which a person passes from an entrance region into a passage region. The passage barrier has a drive drive unit. The drive has an output unit including a hollow shaft having an outer shell surface. The hollow shaft has a barrier element mount formed for fixing a plate-shaped barrier element on the hollow shaft and is formed substantially in a U-shape. The barrier element is fixed between the limbs of the barrier element mount, wherein at least two adhesive grooves are provided on the inside at the base of the barrier element mount. At least two opposing adhesive grooves are provided for receiving an adhesive on the inside on both limbs of the barrier element mount and opposing grooves are formed on the inside at distal ends of the barrier element mount.

    Abstract: The present invention relates to a sectional lifting door system. When the system is in normal operation, a door operator drives a cable drum to wind or unwind a cable for lifting or lowering slats. During a process of lowering the slats, if the slats is stopped or slowed unexpectedly (e.g. the slats hit an obstacle below), the door operator is disconnected from a shaft automatically. At this time, even if the door operator is still activated, the shaft does not rotate, the cable drum does not unwind the cable so that a certain tension force can be maintained on the cable and that the cable is prevented from loosening from the drum, thereby preventing the slats from falling off. Also, it can avoid the situation that the weight of the slats is completely applied to the obstacle because the cable drum continuously unwinds the cable.

    Abstract: To provide a hinge device with an actuator unit such as a rotation dumper or the like which may omit engraving and may make appearance good by narrowing a joint. By a hinge device 3, a second member 2 is connected to a first member rotatably. A first cooperation part 11 of the hinge device 3 is rotatably fixed to the first member 1. A connection member 30 is connected to the first cooperation part 11 rotatably about a first axis line L1 and then is fixed rotatably to the second member 2. A second cooperation part 22 is connected to a connection member 30 rotatably about a second axis line L2 and then is made to cooperate with the first cooperation part 11. A first actuator 41 of an actuator unit 40 such as a rotation dumper or the like is fixed rotatably to the second cooperation part 22 and then a second actuator 42 is fixed rotatably to the second member 2. When the second member 2 is made to rotate, the second cooperation part 22 rotates about the first axis line L1 with respect to the first cooperation part 11 and rotates about the second axis line L2 with respect to the second actuator 42.

    Abstract: An inductive receiving device is provided, including a main body and an actuating unit which has at least one contact portion, a processing unit and a driving unit. The main body has a shell body which has a through opening normally blocked by a blocking portion of a doorstop assembly, and when the doorstop assembly is in an opening position. The processing unit is in communication with the at least one contact portion and the driving unit, the driving unit is connected to the doorstop assembly, the contact portion transfers a pressure variation into an opening signal and transmitting the opening signal to the processing unit, as receiving the opening signal, the processing unit transmits an actuating signal to the driving unit, and the driving unit drives the doorstop assembly to swing to the opening position.
