Abstract
Abstract In a battery powered material handling truck in which the batteries are located beneath a panel on which are mounted the controls, a pivoted construction is provided permitting both the panel and controls to swing up and forward away from their normal position above the batteries thereby providing a clear space above the batteries so that an overhead hoist may be used to remove them.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
167 words
In a battery driven material handling truck including a frame, an operator''s platform carried by said frame, a battery located in front of said platform, a control panel normally positioned over said battery, said panel hinged to said frame for upward forward swinging movement to a position vertically clear of said battery, control levers pivotally mounted on said panel, truck operating mechanisms carried by said frame, linkages connecting said levers are in OFF position, whereby when said levers are in OFF position, whereby when said levers are in OFF position, said panel and levers mounted thereon may be swung fOrwardly out of vertical alignment with said battery without disconnection of said linkages, and when said panel has been swung forwardly, said lever actuated linkages that are above their points of pivotal connection along the line of said pivots having their direction of lever induced movement changed through a substantial angle unacceptable by said linkages and mechanisms below said line of pivots whereby said mechanisms cannot be energized.
Claim 2
Dependent Claim
167 words
In a battery driven material handling truck including a frame, an operator''s platform carried by said frame, a battery located in front of said platform, a control panel normally positioned over said battery, said panel hinged to said frame for upward forward swinging movement to a position vertically clear of said battery, control levers pivotally mounted on said panel, truck operating mechanisms carried by said frame, linkages connecting said levers are in OFF position, whereby when said levers are in OFF position, whereby when said levers are in OFF position, said panel and levers mounted thereon may be swung fOrwardly out of vertical alignment with said battery without disconnection of said linkages, and when said panel has been swung forwardly, said lever actuated linkages that are above their points of pivotal connection along the line of said pivots having their direction of lever induced movement changed through a substantial angle unacceptable by said linkages and mechanisms below said line of pivots whereby said mechanisms cannot be energized.
Claim 3
Dependent Claim
41 words
The construction as set forth in claim 1, said frame having mounted thereon an overhead guard normally located over said operator''s platform, and means permitting movement of said guard forwardly to a position beyond the transverse center line of said battery.
Claim 4
Dependent Claim
31 words
The construction as set forth in claim 2, said guard being mounted on said frame by spaced members pivoted to said frame and means for limiting forward movement of said guard.
Claim 5
Dependent Claim
31 words
The construction as set forth in claim 1, said control levers on said panels including at least a motor control lever and a lever for controlling movement of a lifting fork.
Claim 6
Dependent Claim
35 words
The construction as set forth in claim 1, at least one of said control levers being mounted on a vertical pivot and at least another of said control levers being mounted on a horizontal pivot.
Claim 7
Dependent Claim
47 words
The construction set forth in claim 1, said panel having downwardly extending end flaps which overlap the upper sides of said battery, said end flaps being hingedly connected to said panel whereby they may be swung upwardly clear of the battery before said panel is swung forwardly.
Claim 8
Dependent Claim
34 words
The construction set forth in claim 1, the hinges between said panel and frame and the pivots in said linkages that are aligned therewith being located vertically close to the plane of the panel.
Claim 9
Dependent Claim
50 words
The construction set forth in claim 1, a brake for said truck and a brake actuating lever pivoted to said frame and operable from OFF to ON position while said panel is in normal position, said panel when in forward position preventing movement of said brake lever to OFF position.
