Wheeled carrier stair sliding system

Abstract

This invention is a luggage construction allowing luggage to be slid, rather than the carried or dragged, up and down stairs. The essence of this invention is the combination of a super extendable/angleable pull handle, fixable in the angled position, with a smooth sliding surface on the stair resting face of the luggage body. The handle, super extended and locked in the angled position, is capable of being gripped comfortably by the user at hip level as the bag is being slid up the stairs. The smooth sliding surface removes protrusions from the bag face which slides along the points of the stairs. A brake device is added to prevent the bag from sliding out of control if it is accidentally released by the user.

1 . The combination of 
 a. smooth sliding surface on the bottom face of luggage, such surface long enough to touch two adjacent step edges so as to present a smooth surface along which the bag can be slid up or down stairs and    b. a variable position handle for the luggage which can function fixed    1. along the axis of the bag allowing the bag to be pulled on its wheels    2. extended at an acute angle to the top of the bag to allowing the handle to be comfortably gripped and the bag slid up or down the stairs while it rests flat against the them on its smooth sliding surface.    
   
   
       2 . a baggage system set forth in  claim 1  which includes an automatic locking unit which fixes the handle of claim one at the desired angle when the bag is to be slid up or down and stairs and which can b readily unlocked to allow the handle to return and be fixed in the pull position.  
   
   
       3 . a baggage system set forth in  claim 1  wherein there is a braking system attached to the stair impacting face of the luggage, comprising a spring loaded flap which is pushed back to a neutral and unobtrusive position by the impacting action of the stairs against its surface as the bag ascends but will obtrusively impact and catch the stairs as the bag descends 
 a spring loaded emergency handle, which when released will actuate the brake action but when held or keeps the brake in the neutral and unobtrusive position    a coil spring and plunger apparatus to keep the brake in a neutral and unobtrusive position when the bag is not being slid on stairs.
