US Patent 10952408 Pet bathtub platform with detachable pet washtub

A planar support platform for mounting a pet washtub on the upper rim of a conventional bathtub. The platform comprises a generally H-shaped frame with a central beam slide-adjustable on a pair of spaced cross-bars that span the width of the bathtub to rest on the bathtub upper rim. The cross-bars include downwardly-extending vertical clamping posts shorter than the height of the bathtub, and adjustably positioned on the cross-bars to engage the inner faces of the bathtub sidewalls with an outward locking force. Pet washtubs for use in combination with the platform are also disclosed, the washtub in one form having a bottom locking plate structure configured to mate with inner and outer mounting features on the platform cross-bars.
