Safety control for baby's walker
First Claim
1. A safety control device and baby'"'"'s walker combination wherein said baby'"'"'s walker includes a pair of spaced apart horizontally extending side rails supported on a plurality of peripherally spaced apart legs depending downwardly therefrom having rollers or wheels to support said walker for rolling movement when in use by a baby and a seat supported between said side rails, said safety control device including connecting means to connect said safety control device to said walker, shiftable traction means shiftable between an engaged position engaging the surface on which said walker is being used and a disengaged position above said surface and being operable to move said walker when in said engaged position in at least one direction away from a particular location, said traction means being inoperable to move said walker and inoperable to restrain movement of said walker when in said disengaged position, power means to operate said traction means for movement of said walker when said traction means is in said engaged position, and control means to direct said power means to begin operating said traction means for said movement of said walker and to discontinue operating said traction means thereby discontinuing such movement of said walker.

Abstract
A safety control for a baby'"'"'s walker comprising a typical baby'"'"'s walker having a horizontally extending peripheral frame supported on four peripherally spaced apart legs having rollers or wheels and a seat secured to and extending downwardly from the peripheral frame for the baby to sit in, the seat having two apertures for the baby'"'"'s legs to extend through and to reach the floor when the baby stands and begins to walk, moving the walker as he goes and using the walker as a support and restraint to keep from falling, the walker in accordance with this invention having a motor connected to drive one or more wheels on command to move the walker and the baby in it away from a location of danger such as a electrical outlet, the head of a stairs, an open window, a hot stove, a whirling fan and the like. A receiver to receive radio frequency or other signals from a remote transmitter and a control mechanism responsive thereto are mounted on the walker for starting, stopping and otherwise controlling operation of the motor and for steering of the walker. A remote transmitter is carried by the person watching the child to signal the control mechanism to move the walker and baby therein back and away from a location of danger when seen to be approaching such location.

- 1. A safety control device and baby'"'"'s walker combination wherein said baby'"'"'s walker includes a pair of spaced apart horizontally extending side rails supported on a plurality of peripherally spaced apart legs depending downwardly therefrom having rollers or wheels to support said walker for rolling movement when in use by a baby and a seat supported between said side rails, said safety control device including connecting means to connect said safety control device to said walker, shiftable traction means shiftable between an engaged position engaging the surface on which said walker is being used and a disengaged position above said surface and being operable to move said walker when in said engaged position in at least one direction away from a particular location, said traction means being inoperable to move said walker and inoperable to restrain movement of said walker when in said disengaged position, power means to operate said traction means for movement of said walker when said traction means is in said engaged position, and control means to direct said power means to begin operating said traction means for said movement of said walker and to discontinue operating said traction means thereby discontinuing such movement of said walker.
- 5. A safety control device and baby'"'"'s walker combination wherein said baby'"'"'s walker includes a pair of spaced apart horizontally extending side rails supported on a plurality of peripherally spaced apart legs depending downwardly therefrom having rollers or wheels and a seat supported between said side rails extending downwardly therefrom, said safety control device including connecting means to connect said safety control device to said walker, shiftable traction means shiftable between an engaged and disengaged position for driving contact with the surface on which said walker is being used when in said engaged position to move said walker in at least one direction away from a particular location, said traction means being out of said driving contact when in said disengaged position, power means to operate said traction means, control means to direct said power means to begin operating said traction means for said movement of said walker and to discontinue operating said traction means thereby discontinuing such movement of said walker, including engage and disengage means to move said traction means into driving contact with said surface on which said walker is being used and out of driving contact therewith.
- 9. A safety control device and baby'"'"'s walker combination, wherein said baby'"'"'s walker includes a pair of spaced apart horizontally extending side rails supported on a plurality of peripherally spaced apart legs depending downwardly therefrom having rollers or wheels and a seat supported between said side rails extending downwardly therefrom, said safety control device including connecting means to connect said safety control device to said walker, shiftable traction means shiftable between an engaged and disengaged position for driving contact with the surface on which said walker is being used when in said engaged position to move said walker in at least one direction away from a particular location, said traction means being out of said driving contact when in said disengaged position, power means to operate said traction means, control means to direct said power means to begin operating said traction means for said movement of said walker and to discontinue operating said traction means thereby discontinuing such movement of said walker, wherein said connecting means includes a frame and connectors to connect a portion of said frame to said side rails of said walker, said traction means includes a first rotatable drive member mounted for rotation on a portion of said frame, a second rotatable drive member mounted for rotation on a portion of said frame and spaced apart from said first rotatable drive member, said power means includes a first motor connected to rotate said first rotatable drive member independently of said second rotatable drive member, a second motor connected to rotate said second rotatable drive member independently or said first rotatable drive member whereby when said first motor rotates said first rotatable drive member while said second motor is not operating to drive said second rotatable drive member said walker is steered in one direction, when said second motor rotates said second rotatable drive member while said first motor is not operating to drive said first rotatable drive member said walker is steered in a second direction, and when both of said motors rotate both of said rotatable drive members simultaneously said walker is moved in a straight line, including a first pressure responsive device having a first ram reciprocally movable relative thereto between a retracted and an extended position, said first pressure responsive device being affixed to said walker at a first location, said first ram having an outwardly extending end connected to move said first rotatable drive member into driving contact with said surface on which said walker is being used when said first ram is in its said extended position and out of driving contact therewith when said first ram is moved to its said retracted position, a second pressure responsive device having a second ram reciprocally movable relative thereto between a retracted and an extended position, said second pressure responsive device being affixed to said walker at a second location spaced apart from said first location, said second ram having an outwardly extending end connected to move said second rotatable drive member into driving contact with said surface on which said walker is being used when said second ram is in its said extended position and out of driving contact therewith when said second ram is moved to its retracted position, and at least one pressure source to move said first and second rams under pressure from at least their retracted position to their said extended position.
