Abstract
Abstract Combined luggage and cart apparatus includes a cart disposed within a luggage case. The cart has tubular legs joined at one end by a base plate. A U-shaped handle is inserted in the legs and a locking arrangement prevents separation of the handle from the legs, once inserted. The locking arrangement includes a sleeve inserted in the legs, and a split ring insertable through the sleeve and held captive on the handle. The sleeve includes a locking tab to engage the legs, and the split ring engages the sleeve when the handle is placed in use.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
189 words
A suitcase apparatus having an outer flexible hollow body defining a substantially enclosed interior, and a cart for supporting the body, the cart comprising: a pair of spaced hollow tubular frame-legs each having a base-end and a handle-end, with at least major portions of the frame-legs disposed within the flexible hollow body; a base bridging the frame-legs, joined to the base-ends thereof; roller means attached to the base, with portions of the hollow body between the base and roller means; handle means for supporting the apparatus extending between the frame-legs and having enlarged leg-engaging ends telescopically engaged with the handle-ends of said frame-legs; and locking means including handle-engaging means on said frame-legs and leg-engaging means on said handle means cooperating together to maintain telescopic engagement with the handle means and the frame-legs, despite pulling forces applied to said handle means in a direction away from said frame-legs, one of said leg-engaging means and said handle-engaging means including a locking socket means for locking the other of said leg-engaging means and said handle-engaging means and defining a through-bore for receiving the other of said leg-engaging means and said handle-engaging means.
Claim 2
Dependent Claim
189 words
A suitcase apparatus having an outer flexible hollow body defining a substantially enclosed interior, and a cart for supporting the body, the cart comprising: a pair of spaced hollow tubular frame-legs each having a base-end and a handle-end, with at least major portions of the frame-legs disposed within the flexible hollow body; a base bridging the frame-legs, joined to the base-ends thereof; roller means attached to the base, with portions of the hollow body between the base and roller means; handle means for supporting the apparatus extending between the frame-legs and having enlarged leg-engaging ends telescopically engaged with the handle-ends of said frame-legs; and locking means including handle-engaging means on said frame-legs and leg-engaging means on said handle means cooperating together to maintain telescopic engagement with the handle means and the frame-legs, despite pulling forces applied to said handle means in a direction away from said frame-legs, one of said leg-engaging means and said handle-engaging means including a locking socket means for locking the other of said leg-engaging means and said handle-engaging means and defining a through-bore for receiving the other of said leg-engaging means and said handle-engaging means.
