Universal wheeled bag system

Abstract

A wheeled bag system having a bag with a handle at one end and a wheel system at the other, with either a concealed or exterior-knob lock moving wheels between exposed and hidden positions by either folding the wheels in and up, or retracting the wheels into a cavity in the wheel system.

I claim: 
     
         1 . A wheeled bag system comprising:
 a bag, having handle and wheel system ends;   a handle at the handle end;   a shuttle-exterior knob lock proximal to the wheel system end, the lock having a first and second position-control plate, the first and second position-control plate movable between exposed and hidden positions, a lock housing with a knob plate parallel to a pulley plate, the knob and pulley plates separated by first and second side plates, the first and second side plates parallel to each other, and perpendicular to the knob and pulley plates, the knob plate attached to a lateral surface of the bag;   a plug channel defined within the knob plate, the plug channel running longitudinally from the wheel system end to the handle end, the plug channel having a hidden-position enlargement at the channel end proximal to the handle end, and an exposed-position enlargement proximal to the wheel system end;   a pulley channel defined within the pulley plate, the pulley channel running longitudinally from the wheel system end to the handle end;   first and second side plate channels defined within the first and second side plates, respectively, the first and second side plate channels running longitudinally from the wheel system end to the handle end, wherein the first and second position-control plates exit lock housing via the first and second side plate channels, respectively;   a knob pin having plug and pulley ends, the pulley end exiting the pulley channel allowing the pulley end to slide along the pulley channel;   a retain ring fixed on the knob pin proximal to the pulley plate end;   a retain ring washer abutting the retain ring distal to the pulley end, the retain washer rotatable around the knob pin;   a spring abutting the retain ring washer, the spring wrapped around the knob pin, whereby the knob pin receives tension drawing the knob pin toward the pulley end of the knob pin;   a plug fixed to the plug end of the knob pin, wherein the plug is too large to fit into the plug channel and the plug is too small to not fit both the hidden-position and exposed position enlargements of the knob plate;   a knob fixed to the plug, distal to the knob plate, wherein the knob does not fit within the hidden-position and exposed position enlargements of the knob plate;   a shuttle, disposed within the lock housing, the shuttle having a rectangular bar shape whereby the shuttle slides smoothly within the lock housing, the shuttle having parallel first and second faces, parallel first and second sides, wherein the first and second faces are perpendicular to the first and second sides, and parallel first and second ends perpendicular to the first and second faces and the first and second sides, the shuttle further having knob-pin aperture defined therein whereby the knob pin passes through the first and second faces, a rectangular-bar hollow defined therein whereby the first and second position control plates enter the first and second sides, first and second position control plate pins inside the rectangular-bar hollow rotatably attaching the first and second position control plates to the shuttle; and   a wheel system at the wheel system end, the wheel system having a housing for receiving at least two wheels, the wheels attached to the position-control plate of the lock, whereby moving the position control plate to the exposed position moves the wheels from the housing to expose the wheels, and moving the first and second position control plates to the hidden position moves the exposed wheels to hide the wheels in the housing.   
     
     
         2 . The wheeled bag system of  claim 1 , further comprising:
 First, second, third and fourth bifold wheel covers, for the first, second, third and fourth wheels respectively, the bifold wheel covers having first and second flaps attached to an edge of the wheel opening, whereby the flexible rubber reinforced at the end of the flap or spring hinge hold the flaps flush with the bottom of the bag when the wheels are in the hidden position, and when the wheels are moving to the exposed position the wheels push the flaps are moving to a perpendicular position to the bottom of the bag, thereby exposing the wheels.   
     
     
         3 . A wheeled bag system comprising:
 a bag, having handle and wheel system ends;   a handle at the handle end;   a shuttle-concealed lock proximal to the wheel system end, the lock having a first and second position-control plates, the first and second position-control plates movable between exposed and hidden positions, a shuttle concealed lock housing having first and second side plates with first and second side plate channels defined therein, the first and second side plates parallel to each other with the first and second side plate channels running longitudinally from the wheel system end to the handle end, wherein the first and second position-control plates exit the concealed lock housing via the first and second side plate channels, respectively;   first and second edges, respectively perpendicularly attached the first and second side plates, whereby the first and second edges attach the concealed lock housing to an interior surface of the bag,
 a back plate perpendicular to and separating the first and second side plates; 
   a shuttle, disposed within the lock housing, the shuttle having a rectangular bar shape whereby the shuttle slides smoothly within the lock housing, the shuttle having parallel first and second faces, parallel first and second sides, wherein the first and second faces are perpendicular to the first and second sides, and first and second ends perpendicular to the first and second faces and the first and second sides, the shuttle further having a rectangular-bar hollow defined therein proximal to the first end, whereby the first and second position control plates enter the first and second sides, and first and second position control plate pins inside the rectangular-bar hollow rotatably attaching the first and second position control plates to the shuttle;   a lever attached to the second end of the shuttle by a lever pin, wherein the lever pin allows the lever and the shuttle to rotatably move from a parallel to a perpendicular position, the lever further having first and second dimples at a lever end distal to the attachment to the shuttle, whereby a user can grab the lever to pull or push the shuttle inside the lock housing, a cylinder catch cavity defined in the lever between the first and second dimples and the lever pin a cylinder catch mechanism with a cylinder spring in a cylinder case, the cylinder spring pushing a cylinder partially from the cylinder case whereby the cylinder engages and secures the lever via the cylinder cavity in a position parallel to the shuttle, placing the wheels of the bag in the hidden position, a magnet attracting plate on the lever, a magnet on the bottom of the bag, whereby the magnet and the magnet plate secures the lever in a position perpendicular to the shuttle, placing the wheels of the bag in an exposed position, and a lever lid covering the lever in the bottom of the bag, the lever lid removable so a user can move the lever to place the wheels in either exposed or hidden positions, whereby the lever lid covers the lever when the lever is not being manipulated; and   a wheel system at the wheel system end, the wheel system having a housing for receiving at least two wheels, the wheels attached to the position-control plate of the lock, whereby moving the position control plate to the exposed position moves the wheels from the housing to expose the wheels, and moving the position control plate to the hidden position moves the exposed wheels to hide the wheels in the housing.   
     
     
         4 . The wheeled bag system of  claim 3 , further comprising:
 First, second, third and fourth bifold wheel covers, for the first, second, third and fourth wheels respectively, the bifold wheel covers having first and second flaps attached to an edge of the wheel opening, whereby the flexible rubber reinforced at the end of the flap or spring hinge hold the flaps flush with the bottom of the bag when the wheels are in the hidden position, and when the wheels are moving to the exposed position the wheels push the flaps are moving to a perpendicular position to the bottom of the bag, thereby exposing the wheels.
