Multi-piece nut for use with a shock

Abstract

A multi-piece nut for use with a shock is provided. The multi-piece nut includes a first nut member and a second nut member removably coupled to the first nut member. The first nut member and second nut member include threads on an inner surface that correspond to each other when coupled together. The multi-piece nut may also include an aperture formed when the first nut member and second nut member are coupled together. The first and second nut members are coupled around a shock absorber, and the shock absorber extends through the aperture and engages the threads. The nut can then be rotated to adjust the spring of the shock.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(15) As discussed above, embodiments of the present invention relate to a multi-piece nut for use with a shock, wherein the multi-piece nut generally comprises a first nut member and a second nut member removably coupled together. The first and second nut members coupled together form a spring nut having an aperture sized and shaped to engage a shock absorber of a coil spring over shock.

(16) Referring to the drawings, FIGS. 2-7 depict a multi-piece nut 20. In some embodiments, nut 20 comprises a first nut member 22 and a second nut member 24. First nut member 22 is removably coupled to second nut member 24. When coupled together, first nut member 22 and the second nut member 24 form an aperture 26. First nut member 22 and second nut member 24 each have an inner surface that comprises a first inner thread 28 and a second inner thread 29 respectively Inner threads 28 and 29 correspond to each other such that when first nut member 22 is coupled to second nut member 24, first inner thread 28 and second inner thread 29 allow for nut 20 to thread onto a shock absorber 12.

(17) First nut member 22 includes a first aperture 30 that corresponds to a second aperture 32 of second nut member 24. Connectors 34 engage first aperture 30 and second aperture 32 in order to removably couple first nut member 22 to second nut member 24. In some embodiments, connector(s) 34 may be a bolt.

(18) Nut 20 comprises a recess 42 that is formed when first nut member 22 and second nut member 24 are coupled together. Recess 42 is sized and shaped to receive a dampening device 40. Dampening device 40 engages first spring 14 when nut 20 is coupled to shock 12. In some embodiments, dampening device 40 is an elastomeric member, such as an O-ring, for example. In some embodiments, dampening device 40 is a washer. In some embodiments, dampening device 40 is some other type of dampening device. Dampening device 40 may be formed of an elastomeric material or other dampening material. Dampening device 40 operates to dampen the vibration and/or noise from a component that may contact nut 20 during operation of the shock. By way of one non-limiting example as shown in FIG. 8, a spring divider 50 may be used to separate first spring 14 from a second spring 15. As the vehicle travels over bumps, shock 12 compresses and spring divider 50 may contact dampening device 40 which engages nut 20. Dampening device 40 operates to dampen the vibration, including sound, that spring divider 50 may otherwise have caused when contacting nut 20 during operation of shock 12.

(19) In operation, nut 20 may be separated wherein first nut member 22 and second nut members 24 are separated from each other. First nut member 22 and second nut member 24 are coupled together around a shock absorber. Connector(s) 34 operates to couple together first nut member 22 and second nut members 24. Once coupled together over shock 12, multi-piece nut 20 may be rotated to adjust the spring rate of the shock absorber.

(20) It will be understood that although the drawings depict a multi-piece nut 20 with first nut member 22 and second nut member 24, the present invention is not limited to two pieces. For example, and without limitation, embodiments of the present invention may include three nut members, four nut members, or any number of pieces to form multi-piece nut 20.

(21) Referring again to the drawings, FIGS. 9-14 depict another embodiment of a multi-piece nut 20. In the embodiment shown in FIGS. 9-14, and some embodiments, nut 20 comprises first nut member 22, second nut member 24, and a third nut member 26. First nut member 22 is removably coupled to second nut member 24 as described above herein, in some embodiments. In the embodiment shown, first nut member 22 further comprises a first outer thread 64 and second nut member 24 further comprises a second outer thread 66 such that first outer thread 64 corresponds to second outer thread 66 when first nut member 22 and second nut member 24 are coupled together. Third nut member 26 comprises a third inner thread 68 and a third outer thread 68. Third nut member 26 is coupled to the assembled first and second nut members 22 and 24 by engaging third inner thread 68 with first outer thread 64 of first nut member 22 and second outer thread 66 of second nut member 24. When first nut member 22 and second nut member 24 are coupled together to form multi-piece nut 20, multi-piece nut 20 comprises an aperture 27. First inner thread 28 of first nut member 22 and corresponding second inner thread 29 of second nut member 24 enable nut 20 to thread onto shock 12.

(22) Coupled first and second nut members 22 and 24 form an inner circumference 70 and a gap 60 along the length of coupled first nut member 22 and second nut member 24. In some embodiments, as coupled first nut member 22 and second nut member 24 are coupled to third nut member 26, coupled first nut member 22 and second nut member 24 rotate to allow first outer thread 62 of first nut member 22 and second outer thread 64 of second nut member 24 to engage third inner thread 66 third nut member 26. The engagement of coupled first and second nut members 22 and 24 with third nut member 26 results in reducing inner circumference 70 of coupled first and second nut members 22 and 24. Gap 60 allows for circumference 70 of coupled first and second nut members 22 and 24 to reduce by allowing a first nut member 22 and of second nut member 24 to move toward each other. Multi-piece nut 20, in this and some other embodiments, is thus clamped onto shock 12 in response to reducing inner circumference 70 of coupled first and second nut members 22 and 24.

(23) Multi-piece nut 20 comprises a recess 42 that is formed in first nut member 22. Recess 42 is sized and shaped to receive a dampening device 40. Dampening device 40 engages a spring when multi-piece nut 20 is coupled to shock 12. In some embodiments, dampening device 40 is an O-ring. In some embodiments, dampening device 40 is a washer or other type of dampening device. Further, dampening device 40 may be formed of an elastomeric material or other dampening material. Dampening device 40 operates to dampen vibration, including sound, of any component that contacts nut 20 during operation of shock 12. A non-limiting example in some embodiments, such as the embodiment shown in FIG. 8, a spring divider 50 may be used to separate first spring 14 from second spring 15. As the vehicle travels over bumps, shock 12 compresses and spring divider 50 may contact dampening device 40 which engages nut 20. Dampening device 40 operates to dampen the vibration and/or sound that might otherwise have been caused by spring divider 50 contacting nut 20 during operation or shock 12.

(24) In operation, nut 20 may be separated wherein coupled first and second nut members 22 and 24 are separated from third nut member 26. Coupled first and second nut members 22 and 24 are coupled together on shock 12 with third nut member 26 by concentrically threading third nut member 26 onto coupled first and second nut members 22 and 24, thus clamping coupled first and second nut members 22 and 24 to shock 12. Once coupled to shock 12, multi-piece nut 120 may be rotated to adjust the spring rate of shock 12.

(25) It will be understood that although the drawings depict a multi-piece nut 20 with a coupled inner first and second nut member 22 and 24 respectively, the present invention is not limited to two or three nut-member pieces comprising coupled nut members 22 and 24. For example, and without limitation, embodiments of the present invention may include three coupled inner nut members, four coupled inner nut members, or any number of coupled inner nut members, with or without third nut member 26, to form multi-piece nut 20.
