Abstract

A saddle and removable extension for a floor jack having a storage assembly is disclosed. A saddle and extension assembly of the floor jack includes a jack saddle fastened to a mounting bracket of a lifting arm and an extension having a flange and an extension saddle. To withstand off-center loading conditions when the floor jack is in an upper extended position, at least one extension fastener is operable to engage with at least one extension bore by fastening the extension to the jack saddle and the mounting bracket of the lifting arm. A storage assembly is provided on a body of the floor jack to house the extension during storage or transport.

First claim

What is claimed:

1 . A saddle and extension assembly for a floor jack comprising:
a jack saddle fastened to a mounting bracket of a lifting arm; an extension including a flange and an extension saddle; at least one extension bore, formed off-center a central axis of the extension and the jack saddle and including a non-threaded portion bored through the flange and the jack saddle, and a threaded portion bored at least partially into the mounting bracket; and at least one extension fastener operable to engage with the at least one extension bore to fasten the extension to the jack saddle and the mounting bracket of the lift arm.

2 . The saddle and extension assembly of claim 1 , further comprising:
a saddle bore, formed about the central axis and including a non-threaded portion bored through the jack saddle and a threaded portion bored at least partially into the mounting bracket; and a saddle fastener operable to engage with the saddle bore to mount the saddle to the mounting bracket of the lift arm.

3 . The saddle and extension assembly of claim 2 , wherein:
the at least one extension bore comprises a first extension bore and a second extension bore; and the at least one extension fastener comprises a first extension fastener and a second extension fastener.

4 . The saddle and extension assembly of claim 1 , wherein the extension includes a raised face on a bottom portion of the flange.

5 . The saddle and extension assembly of claim 4 , wherein the jack saddle includes a recess operable to receive the raised face of the flange.

6 . The saddle and extension assembly of claim 5 , wherein the jack saddle further comprises:
a circumferential saddle ridge, and a plurality of landings disposed on the circumferential saddle ridge.

7 . The saddle and extension assembly of claim 1 , wherein:
the flange further comprises a first telescoping member; and the extension saddle further comprises a second telescoping member, wherein: the second telescoping member is operable to be received in the first telescoping member of the flange.

8 . The saddle and extension assembly of claim 7 , wherein the extension further comprises a height adjustment mechanism, operable to adjust a height and a rotation of the extension saddle relative to the flange.

9 . The saddle and extension assembly of claim 8 , wherein the height adjustment mechanism comprises a pin operable to engage with one or more holes formed in the first telescoping member of the flange and the second telescoping member of the extension saddle to fix the height and the rotation of the extension saddle relative to the flange.

10 . The saddle and extension assembly of claim 1 , wherein the jack saddle includes a jack saddle pad and the extension saddle includes an extension saddle pad.

11 . A floor jack comprising:
a body; a lifting arm pivotally connected to the body operable to move between an upper extended position and a lower retracted position; a mounting bracket pivotally connected to an end of the lifting arm; a jack saddle fastened to the mounting bracket; a removable extension, including a flange, an extension saddle, and a shaft disposed between the flange and the extension saddle; at least one extension bore, including a non-threaded portion bored through the flange and the jack saddle, and a threaded portion bored at least partially into the mounting bracket; at least one extension fastener operable to engage with the at least one extension bore to fasten the removable extension to the jack saddle and the mounting bracket of the lift arm in an extension configuration; and a storage assembly, operable to store the removable extension on the body in a stored configuration.

12 . The floor jack of claim 11 , wherein the storage assembly comprises:
at least one notch formed into a side of the body; and a storage clamp bracket mounted on the body, wherein: the at least one notch is operable to receive a portion of the at least one extension fastener.

13 . The floor jack of claim 12 , wherein:
the storage clamp bracket is operable to releasably secure the removable extension.

14 . The floor jack of claim 12 , wherein:
the storage assembly further comprises a storage fastener; and the removable extension includes at least one threaded storage bore formed centrally on the flange, wherein the storage fastener is operable to engage with the at least one threaded storage bore to releasably secure the removable extension to the body.

15 . The floor jack of claim 12 , wherein:
the at least one threaded storage bore comprises a first threaded storage bore formed off-center a central axis of the flange and a second threaded storage bore formed off-center the central axis of the flange; and the storage assembly further comprises a storage fastener operable to engage either the first threaded storage bore or the second threaded storage bore to releasably secure the removable extension to the body.

16 . The floor jack of claim 11 , wherein the removable extension is positioned generally horizontally in the stored configuration and is positioned generally vertically in the extension configuration.

17 . The floor jack of claim 11 , further comprising:
a saddle bore, formed centrally on the saddle and including a non-threaded portion bored through the jack saddle and a threaded portion bored at least partially into the mounting bracket; and a saddle fastener operable to engage with the saddle bore to fasten the saddle to the mounting bracket of the lift arm.

18 . The floor jack of claim 17 , wherein:
the at least one extension bore comprises a first extension bore and a second extension bore; and the at least one extension fastener comprises a first extension fastener and a second extension fastener.

19 . The floor jack of claim 11 , wherein the removable extension includes a raised face on a bottom portion of the flange.

20 . The floor jack of claim 19 , wherein the jack saddle includes a recess operable to receive the raised face of the flange.

21 . The floor jack of claim 19 , wherein the jack saddle further comprises:
a circumferential saddle ridge, and a plurality of landings disposed on the circumferential saddle ridge.

22 . The floor jack of claim 11 , wherein the removable extension further comprises a height adjustment mechanism, operable to adjust a length and a rotation of the shaft.

23 . A floor jack comprising:
a body; an extension; and a storage assembly disposed on the body, the storage assembly comprising:
a bracket operable to secure the extension to the body of the floor jack in a stored configuration; and
at least one notch formed into a side of the body, the at least one notch operable to receive a portion of at least one extension fastener.

24 . The floor jack of claim 23 , wherein the extension is positioned generally horizontally in the stored configuration.

25 . The floor jack of claim 23 , wherein the extension is positioned at least partially between a first side and a second side of the body of the floor jack in the stored configuration.

26 . The floor jack of claim 23 , wherein the bracket is a storage clamp bracket mounted on the body and operable to releasably secure the extension to the body of the floor jack.

27 . The floor jack of claim 23 , wherein:
