Total Claims: 5
Claim 1
Independent Claim
245 words
A portable luggage or load carrier comprising, a pair of arms, namely, a first arm and a second arm both of similar shape, each said arm having a central portion and oppositely extending sections, with one of said sections parallel to but offset from the other section, said pair of arms pivotally connected together at their respective central portions so that the arms may be positioned substantially parallel to each other when collapsed and positioned to form a substantially X-configuration when in load carrying position, wheel means secured adjacent the outer end of each of said arms whereby the carrier may be rolled or wheeled on a floor or ground surface, an opening in each of said arms adjacent the outer ends thereof, a pair of straps at each of the opposite ends of said arms, one of each pair of straps anchored to said first arm and passing through the opening in the second arm and the other of said pair of straps anchored to said second arm and passing through the opening in said first arm so that when the ends of the opposite straps are pulled outwardly away from each other the pair of arms will pivot toward each other, and means associated with each pair of straps and extending over the luggage or load supported on said carrier to secure said luggage or load on said carrier whereby the luggage or load may be moved with the movement of said carrier.
Claim 2
Dependent Claim

A portable luggage or load carrier comprising, a pair of arms, namely, a first arm and a second arm both of similar shape, each said arm having a central portion and oppositely extending sections, with one of said sections parallel to but offset from the other section, said pair of arms pivotally connected together at their respective central portions so that the arms may be positioned substantially parallel to each other when collapsed and positioned to form a substantially X-configuration when in load carrying position, wheel means secured adjacent the outer end of each of said arms whereby the carrier may be rolled or wheeled on a floor or ground surface, an opening in each of said arms adjacent the outer ends thereof, a pair of straps at each of the opposite ends of said arms, one of each pair of straps anchored to said first arm and passing through the opening in the second arm and the other of said pair of straps anchored to said second arm and passing through the opening in said first arm so that when the ends of the opposite straps are pulled outwardly away from each other the pair of arms will pivot toward each other, and means associated with each pair of straps and extending over the luggage or load supported on said carrier to secure said luggage or load on said carrier whereby the luggage or load may be moved with the movement of said carrier.
Claim 3
Dependent Claim
74 words
A carrier as set forth in claim 1 in which the arms have upwardly extending ends which are adapted to engage the sides of the load and in which the means connected to each pair of straps is elastic and when around the load urges the arms in a direction towards each other so that the upwardly extending ends clamp against the sides of the load to firmly secure the load to the carrier.
Claim 4
Dependent Claim
30 words
A carrier as set forth in claim 1 in which each of the arms or members is longitudinally adjustable to extend the length of each of said arms or members.
Claim 5
Dependent Claim
91 words
A carrier as set forth in claim 3 in which the arms or members each has a central hub portion where the Arms or members are pivotally connected to each other and where each of said arms includes a fixed arm section and an extensible arm section coupled to said fixed arm section to permit elongation of each arm in any desired position and in which the extensible arm section supports an upwardly extending end which is adapted to engage the sides of the load or luggage supported on said carrier.
