Title: Equipment for the selection of a lift cage for physically handicapped persons in the case of lifts with immediate alloation of target calls
Inventor: SCHRODER JORIS T
IPC: B66B1/20
Filed: 1991-01-18
Abstract: By this equipment, a cage suitable particularly for physically handicapped passengers can be selected in a lift group controlled by means of group control. For this purpose, call-registering equipments arranged on the storeys display a key, by means of which a switching circuit (20) can be activated. In this case, the switching circuit (20) is connected at the input side with a load store (13) and with a store (RAM1.2) storing the calls for the target storeys, wherein in the absence of an alighting call and for a load which is smaller than a certain load limit value, a first and a second condition for the selection of a cage are fulfilled. The switching circuit (20) is furthermore connected at the input side with the output of a comparator (17), which compares the travelling time of the cage to the call entry storey with the time needed by a physically handicapped person for the path between the actuated call-registering equipment and the shaft door of the lift concerned, wherein a third condition for the selection is fulfilled when the travelling time is greater. When all conditions are fulfilled, the cage selected in such a manner can participate in the call allocation procedure.

Title: Snow sled
IPC: B62B13/10
Filed: 1992-01-23
Abstract: In a ride-on snow sled of the steerable type, a pair of support side runners are fixedly attached to fore and aft vertically oriented legs.  The legs are adapted to slide up and down within hollow tubular frame members.  The upper ends of the front legs of each runner are attached to one another by a non-compressible and non-extendible cable member.  Similarly, the rear pair of legs are connected through a rear tubular frame.  Thus, a shift of weight causing the right ski to extend downwardly from the frame causes a proportional lift or rise in the left ski such that the legs on the left ski retract into the frame. With the skis at different heights proportionate to the slope of the hill, an edging effect is created, permitting the operator to traverse the hill without sliding in much the same manner as a skier traverses a hill.
