Portable, collapsible luggage carrier

A portable, collapsible, luggage carrier comprising:

• a frame and a handle carried thereon;
• wheel means on said frame for transporting said luggage carrier;
• a luggage support platform pivotally mounted to said frame for movement between a collapsed, inoperative, storage position adjacent said frame in an overlapping relationship therewith and an extended, operative position projecting outwardly from said frame;
• platform biasing means for urging said platform toward said storage position;
• and
• releasable latch means for being moved between a latched position to retain said platform in said operative position and a released position to permit said platform to be moved to said storage position by said platform biasing means;
• said carrier including
• (a) a shaft mounted for movement generally parallel to, and along, a portion of said frame, and
• (b) a link pivotally connected at one end to said shaft and pivotally connected at the other end to a portion of said platform at a location spaced from the pivotal mounting of said platform to said frame;
• and
• said platform biasing means including a tension spring biasing said shaft toward one end of said frame.

A portable, collapsible, luggage carrier comprising:

• a frame and a handle carried thereon;
• wheel means on said frame for transporting said luggage carrier;
• a luggage support platform pivotally mounted to said frame for movement between a collapsed, inoperative, storage position adjacent said frame in an overlapping relationship therewith and an extended, operative position projecting outwardly from said frame;
• said frame including a lower frame section and an upper frame section pivotally mounted to said lower frame section for movement between an extended, operative position and a collapsed, inoperative storage position adjacent said lower frame section;
• said lower frame section including at least a first pin mounted for reciprocative movement in, and relative to, said lower frame section for projecting from, and being retracted into, said lower frame section;
• said upper frame section having one end defining at least one receiving cavity for receiving a portion of said pin;
• and
• connecting means for connecting said platform with said pin to move said pin (1) out of said receiving cavity when said platform is moved to said storage position and (2) into said receiving cavity when said platform is moved to its said operative position while said upper frame section is in its said operative position whereby relative transverse displacement of said upper and lower frame sections is prevented.

A portable, collapsible luggage carrier comprising:

• a frame and a handle carried thereon;
• a luggage support platform pivotally mounted to said frame for movement between a collapsed, inoperative, storage position adjacent said frame in an overlapping relationship therewith and an extended, operative position projecting outwardly from said frame;
• a pair of wheel carriages on said frame which each have a rotatable wheel for transporting said luggage carrier;
• a pair of spaced-apart carriage mounting means for mounting said carriages on said frame for pivoting movement between a collapsed, inoperative, storage position in which said wheels overlap each other adjacent said frame and an extended, operative position in which said wheels are disposed generally parallel to each other for rotation about a common axis;
• and
• cam actuation means for effecting said pivoting movement of said carriages in response to pivoting movement of said platform relative to frame;
• and
• said carriage mounting means each including a pair of generally cylindrical, hollow sleeves mounted for rotation on said frame about parallel axes;
• said cam actuation means including cam slots defined in each of said sleeves and a drive shaft mounted in said cam slots perpendicular to said sleeve axes whereby movement of said drive shaft along the plane defined by said axes effects rotation of said sleeves;
• said carrier further including a link pivotally connected at one end to said drive shaft and pivotally connected at the other end to a portion of said platform at a location spaced from the pivotal mounting of said platform to said frame.

• releasable latch means for being moved between a latched position to retain said platform in said operative position and a released position to permit said platform to be moved to said storage position by said platform biasing means;
• said releasable latch means including
• (a) a bracket projecting from said frame;
• (b) a latch member pivotally mounted to said bracket and defining a notch and,
• (c) a torsion spring biasing said latch member in a first direction of rotation;
• and
• said carrier including a shaft connected to said platform and adapted to move along a portion of the length of said frame in response to movement of said platform between said operative position and said storage position whereby said shaft engages said latch member and pivots said latch member outwardly to accommodate receipt of said shaft within said latch member notch when said platform is in said storage position so that said latch means torsion spring holds said latch member engaged with said shaft to latch said platform in said storage position.

• said carrier including
• (a) a rotatable sleeve on said frame,
• (b) a cam track slot defined in said sleeve,
• (c) a shaft extending through said sleeve and engaged with said cam track slot, and
• (d) a link pivotally mounted on one end to said shaft and pivotally mounted at the other end to a portion of said platform at a location spaced from the pivotal mounting of said platform to said frame;
• and
• said platform biasing means including a connector block mounted to said shaft for movement along said frame and includes a tension spring connected between said connector block and said frame for urging said connector block and shaft toward one end of said frame to effect pivoting movement of said platform from said operative position to said storage position.
