Desk moving device

Claim 2

For use when called upon to handle a relatively heavy load, a portable office desk for example, a desk straddling, harnessing, handling and transporting device comprising a pair of aligned vertically disposed leg frames adapted to assume positions adjacent and parallel to exterior surfaces of oriented vertical ends of the desk, each leg frame constituting a manually maneuverable truck, each leg frame being provided with desk engaging, lifting and lowering means, and means operatively linking and connecting upper portions of said leg frames together, said means being adapted when in use to span the top of the desk lengthwise in a plane above the plane of said top and being longitudinally adjustable to cooperate with and accommodate desks of varying lengthwise dimensions, each leg frame being of inverted U-shaped form and embodying a pair of like coplanar vertical legs having upper ends integrally joined by a horizontal bight portion and lower ends each provided with a surface contacting caster, the means linking and connecting the upper portions of said leg frames being longitudinally extensible and retractable and permitting said leg frames to be adjusted toward and from each other while, at the same time, retaining spaced parallel relationship, said desk engaging, lifting and lowering means comprising a jack having complemental plate means releasably and selectively engageable with predetermined portions of the desk, said plate means comprising (1) a lower plate which constitutes a ledge-like foot plate and (2) a complemental alternatively usable upper plate aligned with and disposed in a plane directly above said lower plate and adapted to engage an underneath side of an outstanding overhanging flange marginally encompassing the top of said desk, said upper plate being detachable from said lower plate and, when bodily removed, rendering said lower plate unobstructedly functional.

Claim 3

The device defined in claim 1, and wherein said upper plate is an integral component part of an attachable and detachable adapter and is provided with a pair of depending standards having headed stud means at their lower ends detachably connectible with keeper slots provided therefor in the cooperable lower plate.

Claim 4

The device defined in claim 1, and wherein said plates are rectangular in plan, have upper flat faces, are alike in size, said upper plate having a bottom side provided with a pair of depending coplanar standards which, in conjunction with said upper plate, constitute an alternatively usable adapter, said standards having lower ends equipped with complemental means which is attachably and detachably connectible with said lower plate when being used.

Claim 5

A heavy furniture handling device capable of effectual use by a single workman and expressly designed and adapted to straddle, harness, lift and transport a heavy unwieldy desk, said device comprising a pair of like complemental inverted U-shaped leg frames, each frame comprising a pair of like coplanar vertical legs having upper ends joined by a horizontal bight portion and lower endS each provided with a surface contacting caster and thus providing a pair of manually maneuverable load handling trucks, each leg frame provided with a vertically disposed centrally located load lifting and lowering jack, said jack having a lower end provided with a lower horizontal ledge-like foot plate and at an upper end with an accessible jack operating hand-crank, a pair of spaced parallel horizontal coplanar leg frame assembling and connecting rails in a plane with and connected at outer ends to upper corner portions of said leg frames, each rail being adjustably extensible and retractable and comprising a first elongated tubular member which has an outer end fixed to a cooperating leg frame, and a second elongated member which also has an outer end fixed to a cooperating leg frame, the inner end of said second member telescoping slidingly into the hollow portion of said first tubular member, said first and second members being provided with associatively cooperable interior and exterior anti-friction means which functions to assist in adjusting said members relative to each other, one of said members being equipped with a setscrew which is releasably engageable with the other member in a manner to retain the members against relative sliding movement, and a complemental alternatively usable upper plate aligned with and disposed in a plane directly above and coordinating with said lower plate and adapted to engage an underneath side of an outstanding overhanging flange encompasing the top of said desk, said upper plate being detachable from said lower plate and, when bodily removed, rendering said lower plate unobstructedly functional.

Claim 6

A heavy furniture handling device capable of effectual use by a single workman and expressly designed and adapted to straddle, harness, lift and transport a heavy unwieldy desk, said device comprising a pair of like complemental inverted U-shaped leg frames, each frame comprising a pair of like coplanar vertical legs having upper ends joined by a horizontal bight portion and lower endS each provided with a surface contacting caster and thus providing a pair of manually maneuverable load handling trucks, each leg frame provided with a vertically disposed centrally located load lifting and lowering jack, said jack having a lower end provided with a lower horizontal ledge-like foot plate and at an upper end with an accessible jack operating hand-crank, a pair of spaced parallel horizontal coplanar leg frame assembling and connecting rails in a plane with and connected at outer ends to upper corner portions of said leg frames, each rail being adjustably extensible and retractable and comprising a first elongated tubular member which has an outer end fixed to a cooperating leg frame, and a second elongated member which also has an outer end fixed to a cooperating leg frame, the inner end of said second member telescoping slidingly into the hollow portion of said first tubular member, said first and second members being provided with associatively cooperable interior and exterior anti-friction means which functions to assist in adjusting said members relative to each other, one of said members being equipped with a setscrew which is releasably engageable with the other member in a manner to retain the members against relative sliding movement, and a complemental alternatively usable upper plate aligned with and disposed in a plane directly above and coordinating with said lower plate and adapted to engage an underneath side of an outstanding overhanging flange encompasing the top of said desk, said upper plate being detachable from said lower plate and, when bodily removed, rendering said lower plate unobstructedly functional.
