  • Patent number: 5343988
    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.

  • Patent number: 5136864
    Abstract: A lock for a slide fastener of an article of luggage has a post onto which the gripper flap of the slider of the slide fastener is placed so that the post passes through a hole in the flap. A manually shiftable keeper member on the lock housing has an edge which engages over the gripper flap and is biased against the post by a first spring. A second spring surrounding the post can eject the gripper flap when the keeper member is manually retracted against the force of the first spring. The edge of the keeper member adjacent the post is beveled to facilitate pressing of the gripper flap between the post and the keeper member.
