Abstract
Abstract A substantially constant C-shaped chassis can travel in a first direction and has an open side facing transverse thereto. An upright mast is mounted within the confines of the chassis and can be shiftably displaced in a second direction transverse to the first direction towards and away from the open side. A loadlifting device is provided on the mast, and a displacing arrangement is associated with the mast and with the chassis for displacing the mast with reference to the chassis between the aforementioned positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A wheeled vehicle, comprising a substantially C-shaped chassis adapted for travel in a first direction and having an open side facing transverse thereto; an upright mast mounted within the confines of said chassis for shifting displacement in a second direction transverse to said first direction between one positIon proximal to and an other position inwardly spaced from said open side; load-engaging means on said upright mast; displacing means operatively associated with said upright mast and said chassis for displacing the former with reference to the latter between said positions; guide rail means on said chassis extending in said second direction and having a guide surface provided with an end portion inwardly spaced from said open side and located at a higher level than the level of the remainder of said guide surface; and guide roller means on said mast and rolling on said guide rail means for guiding said mast during movement between said positions thereof, said mast being raised by the difference between said levels on displacement from said one towards said other position.
Claim 2
Dependent Claim
175 words
A wheeled vehicle, comprising a substantially C-shaped chassis adapted for travel in a first direction and having an open side facing transverse thereto; an upright mast mounted within the confines of said chassis for shifting displacement in a second direction transverse to said first direction between one positIon proximal to and an other position inwardly spaced from said open side; load-engaging means on said upright mast; displacing means operatively associated with said upright mast and said chassis for displacing the former with reference to the latter between said positions; guide rail means on said chassis extending in said second direction and having a guide surface provided with an end portion inwardly spaced from said open side and located at a higher level than the level of the remainder of said guide surface; and guide roller means on said mast and rolling on said guide rail means for guiding said mast during movement between said positions thereof, said mast being raised by the difference between said levels on displacement from said one towards said other position.
Claim 3
Dependent Claim
35 words
A vehicle as defined in claim 1, wherein said displacing means comprises at least two parallel arms having respective first end portions pivotally connected with said mast and second end portions connected with said chassis.
Claim 4
Dependent Claim
20 words
A vehicle as defined in claim 2; further comprising connecting means pivotably connecting said second end portions with said chassis.
Claim 5
Dependent Claim
52 words
A vehicle as defined in claim 3, said connecting means comprising a pair of connecting elements, first pivot means pivotably connecting each of said elements with said chassis, and second pivot means pivotably connecting each of said second end portions to one of said elements remote from the respective first pivot means.
Claim 6
Dependent Claim
19 words
A vehicle as defined in claim 4; further comprising coupling means coupling said elements for pivotal movement in unison.
Claim 7
Dependent Claim
64 words
A vehicle as defined in claim 1, said mast having a lower end portion adjacent the ground on which said vehicle travels; and further comprising a support roller provided on said lower end portion and being in engagement with said ground when said mast is in said one position and out of engagement with said ground when said mast is in said other position.
Claim 8
Dependent Claim
59 words
A vehicle as defined in claim 1, said chassis having two longitudinally spaced terminal portions; further comprising a pair of steerable wheels on one of said terminal portions, a driven wheel at the other of said terminal portions, and at least one supporting wheel also on the other of said terminal portions in the vicinity of said driven wheel.
Claim 9
Dependent Claim
57 words
A vehicle as defined in claim 7; further comprising an additional supporting wheel also on said other terminal portion in the vicinity of said driven wheel, both of said supporting wheels being at least substantially coaxial with said driven wheel; and further comprising adjustable biasing means adjustably biasing said supporting wheel into supporting engagement with the ground.
Claim 10
Dependent Claim
44 words
A vehicle as defined in claim 7, one of said steerable wheels being offset relative to the other of said steerable wheels longitudinally of said chassis towards the middle thereof; and further comprising linkage means linking said one steerable wheel with said driven wheel.
