Abstract
A wheeled suitcase has a handle connected via a cabling mechanism to a brake or lock for at least one wheel. A first spring mechanism acts upon the brake or lock in a locking direction with a lesser force than that of a second spring mechanism acting upon the cabling mechanism in the opposite direction. Engagement of the handle by the user releases the brake. The relaxation of the second spring mechanism allows the first spring mechanism to reengage the brake when the handle is released.

An article of luggage, comprising:
- a traveling case having a bottom;
- at least three rollers on said bottom enabling rolling of said case upon a surface upon free rotation of said rollers;
- rotation-blocking means at at least one of said rollers engageable to prevent rotation of said one of said rollers and thereby prevent rolling of said case upon said surface;
- first spring means for biasing said rotation-blocking means in a direction to engage said rotation-blocking means;
- means defining a movable handle on said case upon gripping by a user to draw said case over said surface;
- coupling means operatively connected to said rotation-blocking means and to said handle means stressing said first spring means upon gripping of said handle means by said user and for disengaging said rotation-blocking means to enable rotation of said one of said rollers;
- and
- second spring means acting upon said coupling means and via said coupling means upon said rotation-blocking means for urging said rotation-blocking means out of engagement, said second spring means being prestressed at a greater force than said first spring means.
