Abstract
Abstract A bicycle seat supporting device is of the type having a shock absorber mounted within an elongated tubular housing which telescopingly receives a lower end of a shaft opposite to the upper seat mounting portion, a roller bearing being positioned to engage a flat surface portion on the shaft to prevent relative rotation between the shaft and housing, and an adjustable locking member effectively renders the shock absorber unit inoperative by preventing longitudinal movement between the shaft and the housing member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
146 words
A bicycle seat-supporting device comprising: an elongated shaft having an upper seat-mounting portion and a flat surface portion extending along an exterior surface lengthwise of said shaft beneath said seat-mounting portion; an elongated tubular housing member to telescopingly receive an end of said shaft opposite to said seat-mounting portion; bearing means mounted on said housing member to engage said flat surface portion whereby to prevent relative rotation between said shaft and said housing member while permitting said shaft to move longitudinally with respect to said housing member; shock absorbing means in said housing member to yieldingly resist downward movement of said shaft relative to said housing member; and adjustable locking means on said housing member for releasably engaging said shaft to prevent relative longitudinal sliding movement between said shaft and said housing member independently of the engagement between said bearing means and said flat surface portion.
Claim 2
Dependent Claim
146 words
A bicycle seat-supporting device comprising: an elongated shaft having an upper seat-mounting portion and a flat surface portion extending along an exterior surface lengthwise of said shaft beneath said seat-mounting portion; an elongated tubular housing member to telescopingly receive an end of said shaft opposite to said seat-mounting portion; bearing means mounted on said housing member to engage said flat surface portion whereby to prevent relative rotation between said shaft and said housing member while permitting said shaft to move longitudinally with respect to said housing member; shock absorbing means in said housing member to yieldingly resist downward movement of said shaft relative to said housing member; and adjustable locking means on said housing member for releasably engaging said shaft to prevent relative longitudinal sliding movement between said shaft and said housing member independently of the engagement between said bearing means and said flat surface portion.
Claim 3
Dependent Claim
28 words
A device according to claim 1, said bearing means including a roller bearing member mounted for rotation about an axis transverse to the longitudinal axis of said shaft.
Claim 4
Dependent Claim
28 words
A device according to claim 1, said bearing means and said locking means disposed in axially spaced relation to one another in a recessed portion of said housing.
Claim 5
Dependent Claim
21 words
A device according to claim 1, said locking means releasably but clampingly engaging said shaft whereby to vertically adjust said seat.
Claim 6
Dependent Claim
50 words
A device according to claim 1, said locking means disposed in a recessed portion in a sidewall of said housing and including a brake pad in facing relation to said flat surface portion, and threaded adjustment means for urging said brake pad into frictional engagement with said flat surface portion.
Claim 7
Dependent Claim
115 words
A seat-supporting device for a bicycle or motorcycle comprising: an elongated shaft having an upper seat-mounting portion and a flat surface portion extending along an exterior surface lengthwise of said shaft beneath said seat-mounting portion; an elongated tubular housing member to telescopingly receive an end of said shaft opposite to said seat-mounting portion; bearing means in the form of a roller bearing mounted in fixed relation to said housing member in rollable engagement with said flat surface portion whereby to prevent relative rotation between said shaft and said housing member; and adjustable locking means on said housing member for releasably engaging said shaft to prevent relative longitudinal movement between said shaft and said housing member.
Claim 8
Dependent Claim
115 words
A seat-supporting device for a bicycle or motorcycle comprising: an elongated shaft having an upper seat-mounting portion and a flat surface portion extending along an exterior surface lengthwise of said shaft beneath said seat-mounting portion; an elongated tubular housing member to telescopingly receive an end of said shaft opposite to said seat-mounting portion; bearing means in the form of a roller bearing mounted in fixed relation to said housing member in rollable engagement with said flat surface portion whereby to prevent relative rotation between said shaft and said housing member; and adjustable locking means on said housing member for releasably engaging said shaft to prevent relative longitudinal movement between said shaft and said housing member.
Claim 9
Dependent Claim
44 words
A device according to claim 6, wherein said housing member extends in an upward rearward direction, and said roller bearing is mounted on a rearward inclined surface portion of said housing for rotation about an axis transverse to the longitudinal axis of said shaft.
Claim 10
Dependent Claim
30 words
A device according to claim 6, said roller bearing means and said locking means disposed in axially spaced relation to one another in a recessed portion of said housing member.
Claim 11
Dependent Claim
21 words
A device according to claim 6, said locking means releasably but clampingly engaging said shaft whereby to vertically adjust said seat.
Claim 12
Dependent Claim
51 words
A device according to claim 6, said locking means disposed in a recessed portion in a sidewall of said housing member and including a brake pad in facing relation to said flat surface portion, and threaded adjustment means for urging said brake pad into frictional engagement with said flat surface portion.
Claim 13
Dependent Claim
40 words
A device according to claim 10, said threaded adjustment means including a lever arm for manually rotating said threaded adjustment means and an end stop in the path of said lever arm to limit tightening of said treated adjustment means.
Claim 14
Dependent Claim
39 words
A device according to claim 11, said threaded adjustment means including a threaded stem having an enlarged head, in said lever arm including a cap and having means releasably connecting said cap to said enlarged head of said stem.
