Battery case

A riding scooter that may be assembled and dis-assembled without the use of tools is formed of components of a size and weight such that they may be handled by a person of modest physical strength. The scooter's front and rear sections have overlapping interengaging parts that are biased together in the operative position by the weight of the sections alone. Batteries for electrical power are contained within casings which are cooperatively retained within a battery housing and which also permit the batteries to be simultaneously electrically connected to the vehicle electrical system upon insertion of the battery casings within the battery housing. A steering tiller is detachably mounted to the front steering yoke being retained in an operative position by a quick release locking collar. Control for forward and reverse movement is accomplished through linkage which permits convenient manipulation of the control handle while providing maximum adjustment of an electric potentiometer which controls the electric motor; and, the seat assembly is designed to retain a selected adjustment from disassembly to assembly and further acts to reinforce the biased engagement of the front and rear sections of the scooter.

Disassemblable riding scooter

A pulmonary exercising device having a first mode of operation in which the device provides a visual indication of the volume of inspired air and a second, subsequent mode of operation in which the device provides a visual indication of the rate of inspiration of air. The device has an axially-extending housing with a side wall sealed to a base member. A hollow tubular member surrounds an opening formed in the center of the base and extends axially to the top of the housing. A bellows is positioned within the housing and has its bottom portion sealed to peripheral portions of the base. A bushing is positioned in a central, top portion of the bellows so that the bellows is able to move up and down on the tubular member. The interior of the bellows forms a first chamber within the housing, with the remaining portion of the housing forming a second chamber. An opening is formed in an upper portion of the tubular member so that a user of the device is able to withdraw air from the second chamber through the tubular member, a channelway associated with the opening formed in the center of the base, and tubing extending between the channelway and user. Openings formed in the base communicate the interior of the bellows with the ambient environment. The length of the bushing is less than the length of the opening formed in the tubular member so that the opening communicates with the interior of the bellows, or first chamber, after the bottom of the bushing passes the bottom of the opening.
