A cable operated shopping cart brake apparatus for fitting to an existing shopping cart or other like wheeled vehicle to provide selectively impeded movement. The cable assembly connects a master brake assembly to a slave brake assembly. The cable attachment on the master assembly is reversible, whereby in one mode the resting position of the actuator engages the cart brake, thereby impeding cart movement. The reversed mode provides disengagement of the brake in the rest position of the actuator. The actuator position is lockable so that the above 2 modes are possible. A button of the lock provides disengagement.

What is claimed is: 1. A cable actuated shopping cart brake for attachment to a wheeled shopping cart or the like, the cart brake comprising: a master assembly for attachment to a handle or a frame of the cart, the master assembly comprising: a master body; a groove in the master body, the groove for mating to a side of the cart handle; a half sleeve of the master body, the half sleeve for mating to a side of the cart handle opposite the master body of the master assembly; a plurality of fasteners for affixing the half sleeve to the master body, around the cart handle; a pivot within the master body; a flexible cable assembly having two ends, one end of the cable assembly fitted to the master body; a cable within the cable assembly, the cable having a rod end and a flange end; the rod end of the cable fitted to the pivot within the master body; an actuator, a part of the actuator pivotally fitted through the master assembly, the actuator connected to the pivot, whereby movement of the actuator rotates the pivot and alters the amount of cable within the master body; a slave assembly for attachment to the frame of the cart, the slave assembly comprising: a slave body; a groove in the slave body, the groove for mating to a side of the frame; a half sleeve of the slave body, the half sleeve for mating to a side of the frame opposite the slave body of the slave assembly; a plurality of fasteners for affixing the half sleeve to the slave body, around the frame; a bore within the slave body; a bore seat within the bore; a piston slideably disposed within the bore, the piston connected to the flange end of the cable; a compression spring within the bore, the spring acting to move the piston away from the bore seat, whereby movement of a part of the piston out of the bore enables piston contact with one of the wheels of the cart, thereby impeding cart movement. 2. The apparatus in claim 1 wherein the cable assembly further comprises: a cable; a sheath surrounding a substantial amount of the cable; a sheath cap on an end of each end of the sheath; a cap seat on the master assembly; a cap seat on the slave assembly. 3. The apparatus in claim 1 wherein the actuator of the apparatus comprises: a pivot connection connecting the actuator to the pivot within the master body; a first bend proximal to the master body; an extension extended from the first bend to a second bend; a transverse from the second bend, the transverse for positioning proximal to the cart handle. 4. The apparatus in claim 1 wherein the actuator is lockable. 5. The apparatus in claim 2 wherein the actuator is lockable. 6. The apparatus in claim 3 wherein the actuator is lockable. 7. A cable actuated shopping cart brake for attachment to a wheeled shopping cart, the cart brake comprising: a master assembly for attachment to a handle or a frame of the cart, the master assembly comprising: a master body; a groove in the master body, the groove for mating to a side of the cart handle; a half sleeve of the master body, the half sleeve for mating to a side of the cart handle opposite the master body of the master assembly; a plurality of buttresses incorporated into the half sleeve; a plurality of fasteners for affixing the half sleeve to the master body, around the cart handle, each fastener passing through a buttress; a pivot chamber within the master body; a cylindrical pivot within the pivot chamber; a flexible cable assembly having two ends, one end of the cable assembly fitted to the master body; a cable within the cable assembly, the cable having a rod end and a flange end; the rod end of the cable fitted to the pivot within the master body; an actuator, a part of the actuator movably fitted through the master assembly, the actuator connected to the pivot, whereby movement of the actuator rotates the pivot and alters the amount of cable within the master body; a slave assembly for attachment to the frame of the cart, the slave assembly comprising: a slave body; a groove in the slave body, the groove for mating to a side of the frame; a half sleeve of the slave body, the half sleeve for mating to a side of the frame opposite the slave body of the slave assembly; a plurality of buttresses incorporated into the half sleeve; a plurality of fasteners for affixing the half sleeve to the master body, around the cart handle, each fastener passing through a buttress; a bore within the slave body; a bore seat within the bore; a piston slideably disposed within the bore, the piston connected to the flange end of the cable; a compression spring within the bore, the spring acting to move the piston away from the bore seat, whereby movement of a part of the piston out of the bore enables piston contact with one of the wheels of the cart, thereby impeding cart movement. 8. The apparatus in claim 7 wherein the cable assembly further comprises: a cable; a sheath surrounding a substantial amount of the cable; a sheath cap on an end of each end of the sheath; a cap seat on the master assembly; a cap seat on the slave assembly. 9. The apparatus in claim 7 wherein the actuator of the apparatus comprises: a first bend in the actuator, proximal to the master body; an extension extended from the first bend to a second bend; a transverse from the second bend, the transverse for positioning parallel to the cart handle. 10. The apparatus in claim 7 wherein the actuator is lockable. 11. The apparatus in claim 8 wherein the actuator is lockable. 12. The apparatus in claim 9 wherein the actuator is lockable. 13. A cable actuated shopping cart brake for attachment to a wheeled shopping cart, the cart brake comprising: a master assembly for attachment to a handle or a frame of the cart, the master assembly comprising: a master body; a groove in the master body, the groove for mating to a side of the cart handle; a half sleeve of the master body, the half sleeve for mating to a side of the cart handle opposite the master body of the master assembly; a plurality of buttresses incorporated into the half sleeve; a plurality of fasteners for affixing the half sleeve to the master body, around the cart handle, each fastener passing through a buttress; a pivot chamber within the master body; a cylindrical pivot within the pivot chamber; a lock foramen within the pivot; a flexible cable assembly having two ends, one end of the cable assembly fitted to the master body; a cable within the cable assembly, the cable having a rod end and a flange end; the rod end of the cable fitted to the pivot within the master body; an actuator connected to the pivot; a first bend in the actuator, the first bend proximal to the master body; an extension extended from the first bend to a second bend; a transverse from the second bend, the transverse for positioning parallel to the cart handle; whereby movement of the actuator rotates the pivot and alters the amount of cable within the master body; a lock joined to the master assembly; a lock button within the lock; a lock pin extended from the lock button, the lock pin selectively inserted into the lock foramen in the pivot; a compression spring within the lock, the compression spring acting to release the lock pin from the lock foramen of the pivot; a slave assembly for attachment to the frame of the cart, the slave assembly comprising: a slave body; a groove in the slave body, the groove for mating to a side of the frame; a half sleeve of the slave body, the half sleeve for mating to a side of the frame opposite the slave body of the slave assembly; a plurality of buttresses incorporated into the half sleeve; a plurality of fasteners for affixing the half sleeve to the master body, around the cart handle, each fastener passing through a buttress; a bore within the slave body; a bore seat within the bore; a piston slideably disposed within the bore; a flange receptacle within the piston, the flange receptacle for removable receipt of the flange end of the cable; a compression spring within the bore, the spring acting to move the piston away from the bore seat, whereby movement of a part of the piston out of the bore enables piston contact with one of the wheels of the cart, thereby impeding cart movement.
