Wall-clambering toy space bug

Claim 2

A wall clambering toy comprising: a longitudinal frame member having wall-attaching sucker means thereon at the opposite ends thereof; a transverse frame member extending on opposite sides of said longitudinal frame member and having wall-attaching sucker means thereon at the laterally opposite ends thereof; means mounting said members for reciprocal relative longitudinal movement therebetween accompanied by relative vertical movement therebetween in an opposite direction at each end of said reciprocal longitudinal movement; and power-operated means for effecting movements, whereby the sucker means on one member attach to a wall while the other member advances with its sucker means detached relative to the one member, the other member moves toward and attaches its sucker means to the wall, the one member moves away from and detaches its sucker means from the wall, advances and moves toward and attaches its sucker means to the wall, and the cycle is repeated.

Claim 3

The structure defined in claim 1 in which the means for effecting the relative movements comprise: endless rack means mounted to and extending longitudinally of the longitudinal frame; driven gear means mounted to the transverse frame for rotation about a transverse axis and meshing with said rack means.

Claim 4

The structure defined in claim 2 wherein the rack means includes a row of transverse equispaced pins surrounded by endless guide groove means equidistant from said row, and including a shaft extension on the gear means riding in said groove means.

Claim 5

The structure defined in claims 1 or 2 wherein each sucker means includes a stem loosely carried in guide means on the corresponding member for axial and angular movement therein and spring means engaged between said sucker means and its guide means for maintaining said sucker means centered and extended relative to its guide means when not engaged with a wall.

Claim 6

The structure defined in claims 1 or 2 wherein the relative movement effecting means causes forward inclination of each frame member as it moves away from a wall and including a flexible non-stretchable strip attached to and between the rear edge of the rim of each sucker means and the corresponding frame member to pull up said rim on said inclination to facilitate detachment of said sucker means from the wall.

Claim 7

In a wall clambering toy having at least two frame members, means mounting said members for reciprocal relative longitudinal movement therebetween accompanied by relative vertical movement therebetween in an opposite direction at each end of said reciprocal longitudinal movement, and power-operated means for effecting said movements whereby the sucker means on one member attach to a wall while the other member advances with its sucker means detached relative to the one member, the other member moves toward and attaches its sucker means to the wall, the one member moves away from and detaches its sucker means from the wall, advances and moves toward and attaches the sucker means to the wall, and the cycle is repeated, the improvement wherein each sucker means includes a stem loosely carried in guide means on the corresponding member for axial and angular movement therein and spring means engaged between said sucker means and its guide means for maintaining said sucker means centered and extended relative to its guide means when not engaged with a wall.

Claim 8

In a wall clambering toy having at least two frame members, means mounting said members for reciprocal relative longitudinal movement therebetween accompanied by relative vertical movement therebetween in an opposite direction at each end of said reciprocal longitudinal movement, and power-operated means for effecting said movements whereby the sucker means on one member attach to a wall while the other member advances with its sucker means detached relative to the one member, the other member moves toward and attaches its sucker means to the wall, the one member moves away from and detaches its sucker means from the wall, advances and moves toward and attaches the sucker means to the wall, and the cycle is repeated, the improvement wherein each sucker means includes a stem loosely carried in guide means on the corresponding member for axial and angular movement therein and spring means engaged between said sucker means and its guide means for maintaining said sucker means centered and extended relative to its guide means when not engaged with a wall.

Claim 9

In a wall clambering toy having at least two frame members, means mounting said members for reciprocal relative longitudinal movement therebetween accompanied by relative vertical movement therebetween in an opposite direction at each end of said reciprocal longitudinal movement, and power-operated means for effecting said movements whereby the sucker means on one member attach to a wall while the other member advances with its sucker means detached relative to the one member, the other member moves toward and attaches its sucker means to the wall, the one member moves away from and detaches its sucker means from the wall, advances and moves toward and attaches the sucker means to the wall, and the cycle is repeated, the improvement wherein the relative movement effecting means causes forward inclination of each frame member as it moves away from a wall and including a flexible non-stretchable strip attached to and between the rear edge of the rim of each sucker means and the corresponding frame member to pull up said rim on said inclination to facilitate detchment of said sucker means from the wall.

Claim 10

In a wall clambering toy having at least two frame members, means mounting said members for reciprocal relative longitudinal movement therebetween accompanied by relative vertical movement therebetween in an opposite direction at each end of said reciprocal longitudinal movement, and power-operated means for effecting said movements whereby the sucker means on one member attach to a wall while the other member advances with its sucker means detached relative to the one member, the other member moves toward and attaches its sucker means to the wall, the one member moves away from and detaches its sucker means from the wall, advances and moves toward and attaches the sucker means to the wall, and the cycle is repeated, the improvement wherein the relative movement effecting means causes forward inclination of each frame member as it moves away from a wall and including a flexible non-stretchable strip attached to and between the rear edge of the rim of each sucker means and the corresponding frame member to pull up said rim on said inclination to facilitate detchment of said sucker means from the wall.
