Abstract
Abstract Wheel assembly for a container or suitcase comprising a wheel casing adapted to be secured in the container or suitcase and a wheel mounted in a rotatable wheel fork which is movably disposed in the wheel casing so that the wheel can be moved between a parking position in which only a small portion of the wheel projects beyond the wheel casing and a wheeling position outwardly of the casing, the wheel fork being rotatably mounted in a bearing block which is disposed in the wheel casing to be displaceable between an inner and an outer position in which latter position it can be pivoted in the plane of the wheel casing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
A wheel assembly for a container or suitcase comprising in combination: a wheel casing having an open end and being adapted to be secured in the container or suitcase, a wheel fork carrying a rotatably mounted wheel and having an end portion defining a square, a wheel fork supporting block in which said wheel fork is rotatably mounted, means including a pin-and-slot connection for mounting said supporting block in said wheel casing in such a manner that the supporting block is displaceable between an inner and an outer position, blocking means engageable with said supporting block in the inner position thereof to prevent pivotal movement of said block, means adjacent to and within the open end of said wheel casing, defining a square recess for receiving said end portion of said wheel fork, and a tension spring tensioned between points of said wheel casing and said supporting block respectively, which points are so located that in all positions of the supporting block said tension spring tends to draw said wheel into the wheel casing.
Claim 2
Dependent Claim
174 words
A wheel assembly for a container or suitcase comprising in combination: a wheel casing having an open end and being adapted to be secured in the container or suitcase, a wheel fork carrying a rotatably mounted wheel and having an end portion defining a square, a wheel fork supporting block in which said wheel fork is rotatably mounted, means including a pin-and-slot connection for mounting said supporting block in said wheel casing in such a manner that the supporting block is displaceable between an inner and an outer position, blocking means engageable with said supporting block in the inner position thereof to prevent pivotal movement of said block, means adjacent to and within the open end of said wheel casing, defining a square recess for receiving said end portion of said wheel fork, and a tension spring tensioned between points of said wheel casing and said supporting block respectively, which points are so located that in all positions of the supporting block said tension spring tends to draw said wheel into the wheel casing.
Claim 3
Dependent Claim
69 words
A wheel assembly according to claim 1, wherein said wheel fork has legs which are inclined with respect to its axis of rotation, and wherein two sets of stop means are provided in the wheel casing for limiting the inward pivotal movement of the wheel fork in a respective one of two different positions dependent on the angular position of the wheel fork with respect to the supporting block.
