US 8,132,788 B2 · Partition lifter

Abstract

A wall partition lifter has a vertically extending support beam, a sleeve that is freely slidable therearound and has a ledge extending transversely outwardly from one side. An engagement protuberance extends transversely outwardly from a second side. The engagement protuberance engages and vertically supports the wall partition and may comprise a series of hooks adapted to engage complementary slots in the wall partition, and/or a foot plate for supporting a bottom surface of the wall partition. The support beam has a base with a lip that extends beyond one side thereof. An extension actuator such as a jack may be positioned on the lip and engage the underside of the ledge such that when the jack is extended, the sleeve extends vertically, elevating the wall partition. A plurality of bores in the support beam provide a locking mechanism together with a cotter pin to prevent the sleeve from descending beyond a desired elevation, even when the jack is retracted and/or removed.

Dependent claims

A lifting apparatus for elevating a wall partition extending substantially transversely from a surface, comprising:

a. a support beam engaging and extending substantially transversely away from the surface;
b. a sleeve adapted to engage the support beam in a freely slidable fit and having a ledge extending transversely outwardly therefrom on a first side thereof;
c. an engagement protuberance extending transversely outwardly from a second side of the sleeve and adapted to engage and support the wall partition,
d. an extension actuator having an extension end, the actuator adapted for positioning substantially on the surface such that the extension end engages the ledge for extending the sleeve and the partition transversely away from the surface;
wherein said extension actuator is removable from said lifting apparatus;
and
e. a base mounted to the support beam at one end and protruding transversely away therefrom in a direction away from the engagement protuberance, the extension actuator for positioning thereon when the extension end engages the ledge.
