Abstract

A power pack mount having a generally rectangular-shaped boxlike frame with a pair of arms fixedly secured to the opposite sides thereof, in a substantially vertically disposed position. The ends of the arms are adapted to be attached to a pair of rearwardly and downwardly shiftable pivot point attachments on the vehicle in which the power pack mount is installed, whereby the power pack mount can be easily removed from and replaced within the vehicle.

Claims

1. In combination, a vehicle requiring a source of power and a power pack mount for supporting said source of power, said vehicle comprising shiftable pivot point attachments for said power pack mount, said power pack mount supporting said source of power and having a pair of upwardly extending arms with the free ends thereof formed to engage with respective ones of said pivot point attachments to affix said power pack mount to said vehicle with the center of gravity thereof substantially vertically disposed below said shiftable pivot point attachments, said shiftable pivot point attachments being shifted rearwardly and downwardly to thereby cause said power pack mount to swing free from said vehicle and to be seated on a supporting surface, said arms being releasably disengaged from said pivot point attachments as the latter are further shifted rearwardly and downwardly after said power pack mount is seated on a supporting surface to automatically release said power pack mount from said vehicle.

2. The combination of claim 1, wherein said power pack mount is easily and quickly replaced within said vehicle by engaging said arms with said pivot point attachments and shifting the latter upwardly and forwardly.

3. The combination of claim 1, further including means for releasably securing said power pack mount within said vehicle with the center of gravity thereof positioned forward of said shiftable pivot point attachments, whereby said power pack mount when released from within said vehicle pivotally swings to a substantially vertically disposed position with respect to said pivot point attachments.

4. The combination of claim 3, wherein said means for releasably securing said power pack mount within said vehicle comprises a locking bar affixed to one of said vehicle and said power pack mount and a lever arm for releasably engaging with said locking bar affixed to the other one thereof, said lever arm being biased to automatically lockingly engage with said locking bar when said power pack mount is pivotally swung into said vehicle to secure said power pack mount in position with its center of gravity forward of said pivot point attachments.

5. The combination of claim 1, wherein said pivot point attachments are shiftable rearwardly and downwardly by raising the end of said vehicle opposite the end of which said power pack mount is affixed.

6. The combination of claim 1, wherein said vehicle comprises a frame member, wheels for moving said vehicle supported by said frame member and a housing for generally enclosing the operative elements thereof, said pivot point attachments being formed with said housing and said housing being pivotally swingable with respect to said frame member to shift said pivot point attachments rearwardly and downwardly to permit said power paCk mount to be removed and replaced within said vehicle.

7. The combination of claim 1, wherein said vehicle comprises a frame member, at least one of said pair of wheels for moving said vehicle rotatably secured to an axle supported by said frame member and a housing for generally enclosing the operative elements thereof, said pivot point attachments being formed with said housing above rearwardly of said axle, said power pack mount being releasably secured within said vehicle with the center of gravity thereof positioned forward of said pivot point attachments and generally vertically disposed above said axle, whereby the weight of said power pack mount is substantially located over said axle when installed within said vehicle.

8. The combination of claim 7, wherein said pivot point attachments are shiftable rearwardly and downwardly by raising the end of said vehicle opposite the end at which said power pack mount is affixed, said power pack mount when released from within said vehicle pivotally swinging to a position with its center of gravity substantially vertically disposed with respect to said pivot point attachments and rearwardly of said axle, thereby providing a counter balance which permits the end of said vehicle to be more easily raised.

9. The combination of claim 7, wherein said housing is pivotally swingable about said axle with respect to said frame member to shift said pivot point attachments rearwardly and downwardly, said power pack mount when released from within said vehicle pivotally swinging to a position with its center of gravity substantially vertically disposed with respect to said pivot point attachments and rearwardly of said axle, thereby providing a counter balance which permits the end of said housing to be more easily raised.

10. The combination of claim 1, wherein said power pack mount further includes at least one pair of wheels rotatably secured to it, whereby said power pack mount can be transported by rolling it on said wheels.

11. The combination of claim 1, wherein said power pack mount comprises a generally box-like frame for supporting therein said source of power, said pair of arms being fixedly secured to the opposite sides of said box-like frame.

12. The combination of claim 1, wherein said pivot point attachments comprises a pair of hole-like openings in said vehicle, the upper free ends of said arms of said power pack mount being generally J-shaped and formed to seat within said hole-like openings to releasably affix said power pack mount to said vehicle.

13. The combination of claim 1, wherein said source of power supported by said power pack mount comprises batteries for supplying electrical power for said vehicle.

14. The combination of claim 1, wherein said source of power supported by said power pack mount comprises a motor generator unit for supplying electrical power for said vehicle.

15. The combination of claim 1, wherein said source of power supported by said power pack mount comprises an internal combustion engine.

16. A power pack mount for use in combination with a vehicle requiring a source of power, said vehicle having shiftable pivot point attachments for releasably affixing said power pack mount thereto, said power pack mount supporting said source of power and comprising a pair of upwardly extending arms with the free ends thereof formed to engage with respective ones of said pivot point attachments to releasably affix said power pack mount to said vehicle with the center of gravity thereof substantially vertically disposed below said shiftable pivot point attachments, whereby said power pack mount can be disengaged from said vehicle by shifting said pivot point attachments rearwardly and downwardly to cause said power pack mount to swing free from said vehicle and to be seated on a supporting surface, said arms being releasably disengaged from said pivot point attachments as the latter are further shifted rearwardly and downwardly to automatically release said power pack mount from said vehicle, whereby said power pack mount can be easily and quickly removed from and replaced within said vehicle.

17. The power pack mount of claim 16, wherein said power pack mount further includes at least one pair of wheels rotatably secured to it, whereby said power pack mount can be transported by rolling it on said wheels.

18. The combination of claim 16, wherein said power pack mount comprises a generally box-like frame for supporting therein said source of power, said pair of arms being fixedly secured to the opposite sides of said box-like frame.

19. The combination of claim 16, wherein said pivot point attachments comprise a pair of hole-like openings in said vehicle, the upper free ends of said arms of said power pack mount being generally J-shaped and formed to seat within said hole-like openings to releasably affix said power pack mount to said vehicle.

20. The combination of claim 16, wherein said source of power supported by said power pack mount comprises batteries for supplying electrical power for said vehicle.

21. The combination of claim 16, wherein said source of power supported by said power pack mount comprises a motor generator unit for supplying electrical power for said vehicle.

22. The combination of claim 16, wherein said source of power supported by said power pack mount comprises an internal combustion engine.
