Non-readily detachable luggage support unit

A detachable ground-engaging accessory unit for supporting luggage to be moved from place to place, comprising:

• (a) a stationary base member adapted to be secured to the luggage, said base member having an elongated substantially planar base wall and a pair of side rails each extending at least partially along opposite respective longitudinal side edges of the base wall, said base member also having an elongated cantilever leaf spring which includes one spring end connected to the base wall, an opposite free spring end acting as a locking bolt, and a resilient offset spring portion intermediate the spring ends and having a normal position lying out of the plane of the base wall;
• and
• (b) a movable slide member having an elongated main body for operatively engaging the ground on which the luggage is to be supported, and a pair of side tracks each extending at least partially along opposite respective longitudinal side edges of the main body, said side tracks slidably engaging the side rails for mounting the slide member on the base member for guided sliding movement between a disassembled and an assembled condition, said slide member having a leading detent portion for cammingly engaging and thereby urging the offset spring portion during said sliding movement towards the base wall until the leading detent portion of the slide member is slid past the locking bolt end of the spring, whereupon the spring due to its inherent resilience engages behind the detent portion with snap-type action to thereby secure the slide member and the base member in said assembled condition, said slide member also having in the vicinity of the leading detent portion an access opening which extends through the slide member to expose the spring locking bolt located therebelow in the assembled condition, said access opening being dimensioned to receive therethrough a disassembly tool operative for displacing the offset spring portion back towards the base wall until the free spring end locking bolt clears the detent portion, whereby the slide member is quickly and easily removed from the base member, said leading detent portion in the assembled condition covering and extending beyond the periphery of the offset spring portion and the free spring locking bolt, except at the access opening, to thereby prevent external forces other than from the tool from displacing the offset spring portion and effecting the disassembled condition, whereby the slide member is not readily detachable from the base member during transport of the object.
