Abstract

Abstract A front wheel mounting for bicycles consisting of a pair of arms adapted to be pivoted at their rearward ends to lower ends of the usual fork legs of the bicycle for vertical pivotal movement, the front cycle wheel being rotatably mounted between said arms at selective points along the lengths thereof, and a pair of angled struts each pivoted at its lower end to one of said arms at selective points along the length thereof, and at its upper end to the associated fork leg in spaced relation above the connection of said arm thereto, said struts being resiliently yieldable in compression whereby to provide a spring mounting for said front cycle wheel.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 216 words
A front wheel mounting for a bicycle having a front wheel fork including transversely spaced apart, downwardly extending legs between the lower ends of which the front wheel is normally mounted for rotation on a horizontal transverse axis, said wheel mounting comprising: a. a pair of arms, b. means for connecting the rearward ends of said arms respectively to the lower ends of said fork legs for vertical pivotal movement, said arms extending forwardly, c. means for mounting a front wheel between the forwardly extending end portions of said arms for rotation on a horizontal transverse axis, and d. support means extending between and interconnecting each of said fork legs and its associated arm to resist vertical pivotal movement of said arm, said support means comprising a pair of elongated support struts eaCh comprising a leaf spring longitudinally resiliently yieldable to reduce the effective length thereof, means for attaching one end of each strut to one leg of said fork for pivotal movement on a horizontal transverse axis in spaced relation above the connection of the associated arm thereto, and means attaching the opposite end of each of said struts to its associated arm for pivotal movement on a horizontal transverse axis, in forwardly spaced relation from the connection of said arm to said fork leg.
Claim 2
Dependent Claim 216 words
A front wheel mounting for a bicycle having a front wheel fork including transversely spaced apart, downwardly extending legs between the lower ends of which the front wheel is normally mounted for rotation on a horizontal transverse axis, said wheel mounting comprising: a. a pair of arms, b. means for connecting the rearward ends of said arms respectively to the lower ends of said fork legs for vertical pivotal movement, said arms extending forwardly, c. means for mounting a front wheel between the forwardly extending end portions of said arms for rotation on a horizontal transverse axis, and d. support means extending between and interconnecting each of said fork legs and its associated arm to resist vertical pivotal movement of said arm, said support means comprising a pair of elongated support struts eaCh comprising a leaf spring longitudinally resiliently yieldable to reduce the effective length thereof, means for attaching one end of each strut to one leg of said fork for pivotal movement on a horizontal transverse axis in spaced relation above the connection of the associated arm thereto, and means attaching the opposite end of each of said struts to its associated arm for pivotal movement on a horizontal transverse axis, in forwardly spaced relation from the connection of said arm to said fork leg.
Claim 3
Dependent Claim 25 words
A wheel mounting as recited in claim 1 in which said struts, though generally parallel, are normally bowed away from each other intermediate their ends.
Claim 4
Dependent Claim 53 words
A wheel mounting as recited in claim 1 wherein said arms are sufficiently rigid to resist appreciable flexure thereof in normal usage, and with the addition of a rigid member extending between and rigidly joining said arms adjacent their rearward ends, whereby said arms are prevented from pivoting unequally relative to said fork.
