Abstract

A motor vehicle has an enclosed battery storage compartment with a door separating the compartment from an adjacent support surface that has been roughened to reduce slippage of persons stepping thereon. A battery holder has a mounting base in the compartment and a battery cell support tray mounted on wheels for rolling between a position on top of the mounting base, where the battery cells are housed, and a position on the surface, where the battery cells are inspected and serviced. Mounted to the tray is a handle having a horizontally extending grip portion for grasping to move the handle or tray and a vertical projecting lock portion for engaging a keeper, mounted on the mounting base, to lock the tray in a stationary position. When the handle is in a tray locking position, the grip portion of the handle extends adjacent the tray and the compartment door can be closed, retaining the handle in its locked position. When the door is opened and the handle unlocked, the grip portion of the handle extends outwardly from the tray for moving the tray. Stops limit the outward movement of the tray from the compartment onto the adjacent support surface and guides are provided to restrain tray movement laterally of the normal direction of movement between the compartment and the support surface. Wheel retainers are provided to limit upward movement of the tray above the base.

Claims

1. In a motor vehicle having a battery storage compartment and a support surface located adjacent the compartment, an improved battery holder comprising a mounting base in said compartment, a battery cell support tray mounted on wheels for rolling between a position on the base where battery cells are housed and a position on the support surface where battery cells are serviced and inspected, and means for locking the tray in the position on the base to prevent undesired movement of the tray, said tray having a front panel and a bottom panel, said tray locking means including a vertical sleeve fixed to the front panel, a handle slidably fitted axially within the sleeve and pivotally supported therein for rotation through a horizontal angle, said handle having a grip portion extending outward horizontally above the sleeve and a lock portion projecting downward vertically below the sleeve, a pin extending horizontally from the lock portion of the handle in a vertical plane perpendicular to the grip portion, a keeper mounted on the base for receiving and retaining the lock portion of the handle, said pin extending under the bottom panel of the tray when the grip portion of the handle extends adjacent the tray and thereby preventing the lock portion of the handle from being elevated out of the keeper without rotating the handle to a position where the grip portion extends outwardly from the tray.

2. An improved battery holder as described in claim 1 wherein said tray locking means further includes a radial flange projecting outwardly from the handle above the sleeve, and a compression spring positioned around the handle between the radial flange and the top of the sleeve to urge the handle upward and to require compression before locking the tray.

3. An improved battery holder as described in claim 1 wherein said pin extends outwardly from each side of the lock portion of the handle whereby each end of the pin limits rotational movement of the handle in an elevated position by contact with the front panel to maintain the grip portion of the handle extending outwardly from the tray.

4. An improved battery holder as described in claim 3 which further includes wheel retainers mounted to the base and extending over the tray wheels to limit upward movement of the tray and thereby prevent accidental removal of the lock portion of the handle from the keeper.

5. An improved battery holder as described in claim 1 which further includes at least one stop projecting upward from the end of said mounting base adjacent the support surface, and at least one stop projecting downward from the end of said tray opposite from the support surface to engage the corresponding mounting base stop, thereby limiting movement of the tray outwardly from the battery compartment onto the support surface.

6. An improved battery holder as described in claim 5 which further includes means for restraining upward movement of the tray to maintain the tray stop at a level to engage the mounting base stop.

7. An improved battery holder as described in claim 1 which further includes a guide projecting upward from said mounting base and extending in a direction along the base corresponding with the direction of movement of the tray between the battery storage compartment and the support surface, and a pair of guides projecting downward from the tray on opposite sides of the base guide to restrain the tray from moving laterally of the direction of movement between the compartment and the support surface.

8. In a motor vehicle having a battery storage compartment, a support surface located adjacent the compartment, and a door separating the compartment from the support surface, an improved battery holder comprising a mounting base in said battery compartment, a battery cell support tray mounted on wheels for rolling between a position on the base where battery cells are housed and a position on the support surface where battery cells are serviced and inspected, and means for locking the tray in the position on the base to prevent undesired movement of the tray, said tray locking means including a handle that must be in a locked position before the door can be closed.

9. An improved battery holder as described in claim 8 wherein said handle has a horizontally extending grip portion that must be rotated to a position projecting outwardly from the tray to unlock the tray for movement from the position on the mounting base, said door in a closed position being located to limit rotational movement of the handle and thereby prevent the tray locking means from becoming unlocked.

10. In a motor vehicle having a battery storage compartment and a support surface located adjacent the compartment, said surface having ridges and intermediate valleys in a tread pattern to reduce slippage of persons stepping thereon, an improved battery holder comprising a mounting base in said battery compartment, a battery cell support tray mounted on wheels for rolling between a position on the base where the battery cells are housed and a position on the support surface where the battery cells are serviced and inspected, said tray having wheels of a diameter and a width large enough to roll on top of the surface ridges without dropping into the intermediate valleys, and means for locking the tray in the position on the base to prevent undesired movement of the tray.

11. In a motor vehicle having a battery storage compartment and a support surface located adjacent the compartment, an improved battery holder comprising a mounting base in said compartment, a battery cell support tray mounted on wheels for rolling between a position on the base where battery cells are housed and a position on the support surface where battery cells are serviced and inspected, a handle mounted upon the tray for pivotal movement in a horizontal plane and for slidable movement vertically along its pivotal axis, said handle having a grip portion extending outward horizontally from its pivotal axis adjacent the tray and a lock portion depending downward vertically below the tray, a pin extending horizontally from the lock portion of the handle in a vertical plane perpendicular to the grip portion, a keeper mounted on the base for receiving and retaining the lock portion of the handle to prevent undesired tray movement, said pin extending under the tray above the keeper when the grip portion of the handle extends adjacent the tray and thereby preventing the lock portion of the handle from being elevated out of the keeper without turning the handle to a position where the grip portion extends outwardly from the tray.

12. An improved battery holder as described in claim 11 wherein said tray locking means includes resilient means for urging the handle vertically along its pivotal axis, said resilient means requiring compression to move the handle downward for inserting the lock portion of the handle into the keeper.
