ABSTRACT:

SUMMARY OF THE INVENTION
One of the prime objects of the present invention is to provide a relatively narrow lightweight vehicle of the foregoing character with an automatically locking frame assembly which is activated automatically when the front and rear frame sections are telescopically engaged.
Another object of the invention is to provide an assembly of this type wherein a lever latch, normally maintained in the path of movement of one of the vehicle frame sections, is longitudinally displaced upon relative telescopic movement of the sections to enable the frame sections to be moved into a latching position.
Still another object of the invention is to provide an assembly of this character wherein the lever latch can be rapidly and easily operated by the physically challenged to delatch the sections and permit their relative longitudinal separation.
Another object of the invention is to provide an assembly of this type which is relatively simple in construction and, accordingly, inexpensive to manufacture.
A further object of the invention is to provide a vehicle assembly of this type which is durable and stable, and enhances the safety of operation of the vehicle.
The invention contemplates a dismountable powered vehicle for the physically challenged comprising:
a. a frame having a longitudinally extending floor frame supported on front and rear wheels;
b. a generally vertically extending steering column mounted on the front end of the floor frame and connected to steer the vehicle;
c. a seat supported by the floor frame rearwardly of the steering column;
d. a motor connected to drive the wheels selectively to move the vehicle forwardly or rearwardly;
e. the floor frame having discrete front and rear segments including a longitudinally telescopic coupling assembly comprising a longitudinal part on one of the segments received within a tubular part on the other segment; and
f. a lever latch connected with one of the parts and automatically interacting with the other of the parts upon movement of the parts relatively longitudinally for latching them in locked position.
Other objects and advantages of the invention will become apparent with reference to the accompanying drawings and the accompanying descriptive matter.
