Collapsible locomotion platform with selectively arrestable wheel assembly
First Claim
1. A locomotion platform, comprising:
- a base frame having a front lowermost section and a rear lowermost section, both defining an imaginary horizontal landing plane;
a front wheel assembly and a rear wheel assembly, each configured with a distal end comprising one or more riding wheels and at least one proximal end articulated to said base frame, each one of said front wheel assembly and said rear wheel assembly being independently manipulable between a collapsed position, at which the riding wheels of the respective wheel assembly are disposed on or above the horizontal landing plane, and an extended position, at which the riding wheels of the respective wheel assembly are disposed below the horizontal landing plane;
at least one position fixing mechanism configured to selectively arrest at least one of said front wheel assembly or said rear wheel assembly at any one of one or more intermediate positions between the collapsed position and the extended position; and
at least one activating module configured to induce manipulation of at least one of said front wheel assembly and said rear wheel assembly towards the collapsed position.

Abstract
A locomotion platform comprising: a base frame having front and rear lowermost sections, both defining an imaginary horizontal landing plane; front and rear wheel assemblies, each configured with a distal end comprising riding wheel(s) and at least one proximal end articulated to said base frame, each of said front and rear wheel assemblies independently manipulable between a collapsed position, at which the riding wheels of the respective wheel assembly are disposed on or above the plane, and an extended position, at which the riding wheels of the respective wheel assembly are disposed below the plane; a position fixing mechanism(s) configured to selectively arrest at least one of said front or rear wheel assemblies at one or more intermediate positions between the collapsed and extended positions; and an activating module(s) configured to induce manipulation of at least one of said front or rear wheel assemblies towards the collapsed position.
