Abstract: The pedal-operated scooter is a scooter with a plurality of wheels, which are further defined as including at least one rear wheel and at least one front wheel. The at least one rear wheel is in mechanical connection with a drive sprocket that is in mechanical connection with a pedal sprocket. The pedal sprocket is in mechanical connection with a pair of pedals provided on the scooter. The pair of pedals are able to be manipulated via a rider in order to propel the scooter. Moreover, rotation of the pair of pedals, rotates the pedal sprocket that is attached to the drive sprocket via a chain or belt. The drive sprocket in turn drives the at least one rear wheel. The scooter includes a handlebar, and a seat.

Abstract: A drawer for an airline trolley, which has a generally rectangular tray, is closed by a lid. The lid has a flap which is openable, and the drawer has a lock unit with which the flap engages. The lock unit is lockable by a breakable seal. The flap can be hinged about a line extended across the lid at a position forward of the back of the tray. The flap can be connected to the sides of the tray by webs which fold under the flap in its closed position, the webs preventing access to the interior of the tray under the lid. The flap can have a catch at its forward end which engages in a lockable chamber on the front of the drawer, a breakable seal being insertable into the chamber to engage the catch.

Abstract: An automatic conveying device includes a conveyer bracket, a wheel assembly, a transmission mechanism, and a loading assembly. The wheel assembly is rotatably assembled to a bottom portion of the conveyer bracket for supporting the conveyer bracket. The transmission mechanism is assembled within the conveyer bracket and connected with the wheel assembly, thereby driving the wheel assembly to rotate. The loading assembly is mounted upon the conveyer bracket and movably assembled with the transmission mechanism, for accepting objects as a load and driving the transmission mechanism to work. The loading assembly moves downward relative to the conveyer bracket under the weight of the objects placed on the loading assembly, and is capable of moving upward back to its original position, when the objects are removed.
