Abstract

Abstract A luggage carrier intended to be attached over the front wheel of a bicycle contains an attachment device serving for the attachment of the luggage carrier at the steering fork head. To improve the torsional resistance of the luggage carrier and to be able to secure such luggage carrier also at the steering fork heads of existing vehicles without the need to disassemble any parts, the attachment device comprises two caps or hood members intended to engage about both shoulders of the steering fork head. Each of these caps can be fixedly clamped by means of a preferably wedge-shaped clamping body at the related shoulder of the steering fork head.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 256 words
A luggage carrier, comprising: a carrier frame; an attachment means for securing the luggage carrier over a front wheel of a bicycle having a steering fork; said steering fork including a fork head with two shoulders and two fork legs secured at their upper ends to a respective one of said shoulders; said attachment means including two cap members integrally connected to said carrier frame, each of said cap members having a top wall and side walls; each cap member being intended to engage over and about a respective shoulder of said fork head; clamping means, associated with each of said cap members, for fixedly clamping the associated cap member at the related shoulder of said fork head; said clamping means including a clamping wedge having a narrow upper and a broad lower end; each cap member possessing at its side walls an inner concave contact surface engaging about the related shoulder at a surface thereof; said inner concave contact surface being located forwardly in the direction of travel of the bicycle; each cap member further possessing at its opposite side an inclined guide surface for said clamping wedge; said guide surface diverging downwardly away from the related fork leg; each of said clamping wedges including a threaded bore extended downwardly from the narrow upper end thereof; and said clamping means including bolt means for extending through the top wall of the respective cap member and being screwed into the threaded bore of the respective clamping wedge for displaceably shifting said wedge into its clamping position.
Claim 2
Dependent Claim 256 words
A luggage carrier, comprising: a carrier frame; an attachment means for securing the luggage carrier over a front wheel of a bicycle having a steering fork; said steering fork including a fork head with two shoulders and two fork legs secured at their upper ends to a respective one of said shoulders; said attachment means including two cap members integrally connected to said carrier frame, each of said cap members having a top wall and side walls; each cap member being intended to engage over and about a respective shoulder of said fork head; clamping means, associated with each of said cap members, for fixedly clamping the associated cap member at the related shoulder of said fork head; said clamping means including a clamping wedge having a narrow upper and a broad lower end; each cap member possessing at its side walls an inner concave contact surface engaging about the related shoulder at a surface thereof; said inner concave contact surface being located forwardly in the direction of travel of the bicycle; each cap member further possessing at its opposite side an inclined guide surface for said clamping wedge; said guide surface diverging downwardly away from the related fork leg; each of said clamping wedges including a threaded bore extended downwardly from the narrow upper end thereof; and said clamping means including bolt means for extending through the top wall of the respective cap member and being screwed into the threaded bore of the respective clamping wedge for displaceably shifting said wedge into its clamping position.
