Abstract
Abstract A truck for supporting furniture frames or the like comprising a wheeled base structure and a pair of laterally movable supporting elements each of which is mounted on the base structure by two support arms fixed separately to sleeve elements carried exteriorly on longitudinally extending base elements, each support arm extending beyond one end of the sleeve element to which it is fixed and each sleeve element being carried on its base element by longitudinally spaced rollers disposed respectively to ride the upper and lower surfaces of the base element with the roller disposed for riding the upper base element surface being located substantially nearer the end of the sleeve element from which the support arm extends. Additionally, the supporting elements may be mounted on the base element for selective vertical movement with respect thereto and a plurality of jacking legs may be mounted on the base structure with an operating arrangement for simultaneously and selectively lowering these legs to extend beneath the truck wheels whereby the truck is supported solely by these legs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A device for supporting furniture frames or the like during upholstering thereof, said device including a base structure and a pair of spaced supporting elements mounted thereon by means permitting selective lateral movement of at least one of said supporting elements with respect to the other, said mounting means including a sleeve element carried exteriorly on a laterally extending base element for movement therealong and including a support arm fixed to said sleeve element and extending longitudinally beyond one end thereof to a connection with said one of said supporting elements, said sleeve element being carried on said base element by a pair of longitudinally spaced rollers journalled therein and disposed, respectively, to ride the upper and lower surfaces of said base element with the roller disposed for riding said upper base element surface being located substantially nearer said one end of said sleeve element, and the extent of said support arm beyond said one end being sufficient to impose a biasing weight therefrom on said sleeve element by which said spaced rollers are maintained in riding contact with said base element.
Claim 2
Independent Claim
182 words
A device for supporting furniture frames or the like during upholstering thereof, said device including a base structure and a pair of spaced supporting elements mounted thereon by means permitting selective lateral movement of at least one of said supporting elements with respect to the other, said mounting means including a sleeve element carried exteriorly on a laterally extending base element for movement therealong and including a support arm fixed to said sleeve element and extending longitudinally beyond one end thereof to a connection with said one of said supporting elements, said sleeve element being carried on said base element by a pair of longitudinally spaced rollers journalled therein and disposed, respectively, to ride the upper and lower surfaces of said base element with the roller disposed for riding said upper base element surface being located substantially nearer said one end of said sleeve element, and the extent of said support arm beyond said one end being sufficient to impose a biasing weight therefrom on said sleeve element by which said spaced rollers are maintained in riding contact with said base element.
Claim 3
Dependent Claim
52 words
A device for supporting furniture frames or the like as defined in claim 1 and further characterized in that the other of said spaced supporting elements is aLso mounted on said base structure for selective lateral movement by mounting means corresponding to said mounting means for said one of said supporting elements.
Claim 4
Dependent Claim
79 words
A device for supporting furniture frames or the like as defined in claim 1 and further characterized in that said support arm is formed with a straight center portion and opposite end portions extending generally perpendicularly from said center portion in opposite directions, one of said end portions being connected to said sleeve element at a point thereon located between said spaced rollers, and the other of said end portions being connected to said one of said supporting elements.
Claim 5
Dependent Claim
86 words
A device for supporting furniture frames or the like as defined in claim 1 and further characterized in that said one supporting element is connected to its support arm through a pantographic linkage arranged to permit said one supporting element to be moved vertically with respect to said support arm, and in that selectively operable means are associated with said pantographic linkage to cause gradational expansion or contraction of the same for respectively raising or lowering said one supporting element with respect to said support arm.
Claim 6
Dependent Claim
63 words
A device for supporting furniture frames or the like as defined in claim 4 and further characterized in the lower portion of said pantographic linkage is carried by a bracket member slidably mounted on the extending end portion of said support arm for movement between a first position overlapping said extending end portion and a second portion projecting beyond said extending end portion.
