BATHTUB LIFT ASSEMBLY

摘要

A bathtub lift assembly for a bathtub is provided. The bathtub lift assembly comprises: a bathtub frame, a lifting assembly including a vertically-extending lift post mounted to the bathtub frame and translatable between a raised configuration and at least one lowered configuration, a post actuator mounted to the bathtub frame, and a transmission assembly mounted to the bathtub frame and operatively connecting the post actuator and the vertically-extending lift post. The transmission assembly can include a ratio multiplier assembly. The bathtub lift assembly can also include a lift post rotation actuator operatively connected to the vertically-extending lift post and activable to configure the vertically-extending lift post between a loading configuration and a bathing configuration.

1. A bathtub lift assembly for a bathtub having a bathing cavity, the bathtub lift assembly comprising:
a bathtub frame configured to at least partially surround the bathing cavity of the bathtub; a lifting assembly comprising a vertically-extending lift post mounted to the bathtub frame and translatable along a post axis between a raised configuration and at least one lowered configuration; a linear actuator mounted to the bathtub frame and translatable between an extended configuration and a retracted configuration along a linear actuator axis; and a transmission assembly mounted to the bathtub frame and comprising at least one belt or chain defining a closed-loop path with an actuator section extending along the linear actuator axis and a post section extending along the post axis, the vertically-extending lift post being engaged with the at least one belt or chain in the post section and the linear actuator being engaged with the at least one belt or chain in the actuator section, wherein translation of the linear actuator between the extended configuration and the retracted configuration drives the at least one belt or chain along the closed-loop path and the vertically-extending lift post between the raised configuration and the at least one lowered configuration.
