Abstract
Abstract A fending guide plate assembly for vehicles such as lift trucks for mechanically engaging aisle mounted side rails, or the like, by base plate side mounted guide rollers to guide the vehicle along narrow aisles as in warehouses. The base plate is securely mounted by shock absorbers from the vehicle chassis and extends adjacent to the floor under a major portion thereof. The shock absorbers permit the base plate to absorb and cushion forces imposed thereon from any direction relative to the chassis, thus limiting the effect of shock loads encountered, for example, when entering narrow aisle ways between guide rails. Adjustment members, such as bolts, support the guide plate assembly from the floor when it is not engaged with the vehicle and are adjustable to lower and raise the assembly for disengagement from the vehicle or for engagement therewith, the vehicle being driveable onto and from the plate assembly for connection thereto and disconnection therefrom.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
93 words
A guide plate assembly for wheeled vehicles having a frame means, comprising means supporting the guide plate assembly from the vehicle frame, said guide plate assembly including a base plate adjacent the vehicle supporting surface and extending in a plane under the vehicle frame and under a plane which passes through the axes of rotation of the wheels, and side guide roller means mounted at each side of the base plate extending at least partially above and peripherally outwardly of the base plate for guiding the vehicle in a track between guide rails.
Claim 2
Dependent Claim
93 words
A guide plate assembly for wheeled vehicles having a frame means, comprising means supporting the guide plate assembly from the vehicle frame, said guide plate assembly including a base plate adjacent the vehicle supporting surface and extending in a plane under the vehicle frame and under a plane which passes through the axes of rotation of the wheels, and side guide roller means mounted at each side of the base plate extending at least partially above and peripherally outwardly of the base plate for guiding the vehicle in a track between guide rails.
Claim 3
Dependent Claim
44 words
A device as claimed in claim 1 wherein said base plate is a continuous plate extending both longitudinally and transversely under the vehicle frame and having openings formed therein through which extend one or more vehicle wheels for engagement with the vehicle supporting surface.
Claim 4
Dependent Claim
34 words
A device as claimed in claim 1 wherein a plurality of shock absorber means support the base plate from the vehicle frame both at the forward and rearward end portions of the base plate.
Claim 5
Dependent Claim
37 words
A guide plate assembly as claimed in claim 1 wherein shock absorber means are secured at a plurality of locations both to the base plate and to the vehicle inwardly of the periphery of the base plate.
Claim 6
Dependent Claim
73 words
A guide plate assembly as claimed in claim 4 wherein said shock absorbers are secured on one side thereof to the base plate and at the other side thereof are supported from frame members of the vehicle, said shock absorbers being mounted in different positional relationships to the base plate such that the shock absorbers function in combination to absorb forces imposed upon the guide plate assembly both in shear, compression and tension.
Claim 7
Dependent Claim
46 words
A guide plate assembly as claimed in claim 4 wherein said shock absorbers are of a bonded sandwich resilient type having rigid opposite side portions and integral outwardly projecting studs for connection to the base plate on one side and the vehicle on the other side.
Claim 8
Dependent Claim
47 words
A guide plate assembly as claimed in claim 1 wherein guide plate assembly adjustment means are adjustable to lower the base plate to substantially the level of the vehicle supporting surface and to elevate the base plate to a position wherein it is connectible to the vehicle.
Claim 9
Dependent Claim
27 words
A guide plate assembly as claimed in claim 7 wherein the adjustment means comprises a plurality of jack members located at predetermined positions in the base plate.
Claim 10
Dependent Claim
44 words
A guide plate assembly as claimed in claim 1 wherein said side guide roller means comprises a pair of longitudinally spaced side guide rollers located at each side of the base plate and mounted from inverted U-shaped brackets for rotation in a horizontal plane.
Claim 11
Dependent Claim
79 words
A guide plate assembly as claimed in claim 1 wherein said side guide roller means comprises a Pair of longitudinally spaced side guide rollers at each side of the base plate, and a rigid member mounted on the base plate in a predetermined location in relation to each side guide roller such that each guide roller is supported therefrom and the peripheral portion of each guide roller exposed to contact a guide rail is limited by said rigid member.
Claim 12
Dependent Claim
42 words
A guide plate assembly as claimed in claim 10 wherein each of said rigid members comprises a substantially circular member having a cutout peripheral portion overlapped by a circular peripheral portion of each respective guide roller which comprises said exposed roller portion.
Claim 13
Dependent Claim
141 words
A guide plate assembly for wheeled vehicles having a frame means comprising means for supporting the guide plate assembly from the vehicle frame, said guide plate assembly including a base plate adjacent the vehicle supporting surface and extending in a plane under the vehicle frame, side guide roller means mounted at each side of the base plate, extending at least partially above and peripherally outwardly of the base plate and having mounting means associated therewith limiting the peripherally outwardly extending portion of each said guide roller so as to protect each such roller against failure from relatively high impact forces imposed on such rollers, and said base plate having associated therewith adjustment means adjustable to lower the guide plate assembly to substantially the level of the vehicle supporting surface and to raise the guide plate assembly for connection to the vehicle.
Claim 14
Dependent Claim
141 words
A guide plate assembly for wheeled vehicles having a frame means comprising means for supporting the guide plate assembly from the vehicle frame, said guide plate assembly including a base plate adjacent the vehicle supporting surface and extending in a plane under the vehicle frame, side guide roller means mounted at each side of the base plate, extending at least partially above and peripherally outwardly of the base plate and having mounting means associated therewith limiting the peripherally outwardly extending portion of each said guide roller so as to protect each such roller against failure from relatively high impact forces imposed on such rollers, and said base plate having associated therewith adjustment means adjustable to lower the guide plate assembly to substantially the level of the vehicle supporting surface and to raise the guide plate assembly for connection to the vehicle.
Claim 15
Dependent Claim
76 words
A guide plate assembly as claimed in claim 12 wherein a plurality of shock absorber means are secured both to the base plate and to the vehicle inwardly of the peripheral boundary of the base plate, said base plate being a continuous plate extending both longitudinally and transversely under the vehicle frame, and one or more openings in said base plate through which extend one or more vehicle wheels for contact with said vehicle supporting surface.
Claim 16
Dependent Claim
58 words
A guide plate assembly as claimed in claim 13 wherein a plurality of shock absorbers are secured to the base plate at predetermined locations and are adapted to be connected to portions of the vehicle for supporting the guide plate assembly under the vehicle in such a manner that forces in shear, tension and compression are resisted thereby.
Claim 17
Dependent Claim
47 words
A guide plate assembly as claimed in claim 12 wherein each said mounting means comprises a substantially circular member having a cutout peripheral portion overlapped by a circular peripheral portion of each respective guide roller which comprises the limited outwardly extending portion of each said guide roller.
