Abstract
Abstract A trailer frame storage system comprises a plurality of storage units connected closely together in laterally spaced apart condition, each storage unit having a plurality of longitudinally spaced, folding trailer frame support arms each arranged to receive and support a trailer frame for storage in a substantially vertical position in which the trailer frame is rested on its rear end on the ground and its forward end extends upwardly. Each arm is extended, one at a time from rear to front, by movement of the next rearward arm to fully extended position as a trailer frame is rested against it, the frames being transported longitudinally into the storage unit, successively filling the unit from the rear end to the front end. Removal of the stored trailer frames follows the reverse order, and removal of each frame results in it engaging the next adjacent forward arm from which a trailer frame has been removed, to cause said forward arm to be moved toward retracted position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
134 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, and (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for horizontal movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, whereby, to allow extension of the retracted support arms sequentially from the rear end toward the front end of the framework to enable trailer frames to be moved longitudinally closely adjacent the elongated framework for loading trailer frames sequentially from the rear end of the framework toward the front end thereof and unloading in the reverse sequence.
Claim 2
Dependent Claim
134 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, and (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for horizontal movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, whereby, to allow extension of the retracted support arms sequentially from the rear end toward the front end of the framework to enable trailer frames to be moved longitudinally closely adjacent the elongated framework for loading trailer frames sequentially from the rear end of the framework toward the front end thereof and unloading in the reverse sequence.
Claim 3
Dependent Claim
25 words
The storage system of claim 1 including a plurality of support arms mounted on the framework for retractable extension to both sides of the framework.
Claim 4
Dependent Claim
26 words
The storage system of claim 2 including a plurality of said frameworks supported in laterally spaced apart, parallel positions and secured together at their rear ends.
Claim 5
Dependent Claim
127 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, and (c) means operatively engaging the arms for initiating movement of each support arm toward extended position upon movement of the next preceding arm from an intermediate position of extension to fully extended position by engagement of said preceding arm by a trailer frame being positioned for support against said preceding arm.
Claim 6
Dependent Claim
127 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, and (c) means operatively engaging the arms for initiating movement of each support arm toward extended position upon movement of the next preceding arm from an intermediate position of extension to fully extended position by engagement of said preceding arm by a trailer frame being positioned for support against said preceding arm.
Claim 7
Dependent Claim
85 words
The storage system of claim 4 wherein said arm engaging means includes a cam member associated with each support arm and mounted on the framework for movement between a retracted position releasing its associated arm for movement toward extended position and an extended position engaging its associated arm and moving the latter to retracted position, and connector means interengaging each cam member and the next preceding arm for moving the cam member to retracted position upon movement of the associated arm to fully extended position.
Claim 8
Dependent Claim
44 words
The storage system of claim 5 including spring means interengaging the framework and each support arm for urging the latter to said intermediate position of extension, and spring means interengaging the framework and each cam member for urging the latter toward its extended position.
Claim 9
Dependent Claim
44 words
The storage system of claim 4 where in said arm engaging means includes connector means interconnecting adjacent support arms for moving a retracted arm toward extended position upon movement of its connected arm from said intermediate position of extension to said fully extended position.
Claim 10
Dependent Claim
25 words
The storage system of claim 7 including stop means on the framework arranged to engage each support arm for retaining it releasably in retracted position.
Claim 11
Dependent Claim
121 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, and (c) means operatively interengaging each support arm and the framework for moving the arm to fully retracted position upon initial movement of the arm toward retracted position by engagement of said arm by a trailer frame being removed from support by the next preceding arm.
Claim 12
Dependent Claim
121 words
A storage system for trailer frames, comprising: (a) an elongated framework supported in elevated position above a floor in substantially horizontal position and having front and rear ends, (b) a plurality of trailer frame support arms mounted on the framework at longitudinally spaced positions for movement between a retracted position adjacent the framework and an extended position projecting laterally outward of the framework for supporting a trailer frame disposed on end in substantially vertical position, and (c) means operatively interengaging each support arm and the framework for moving the arm to fully retracted position upon initial movement of the arm toward retracted position by engagement of said arm by a trailer frame being removed from support by the next preceding arm.
