Abstract
Abstract It is an object of the invention to provide a bicycle, which starting from a kit of components is very simple to mount, and which in mounted condition in spite of a low price produces a stable bicycle, which is resistant to rough handling and negligence, and which has the requirements for good functioning also after a long time of use. The assembly of bicycle components according to the invention comprises a frame member (1). Furthermore, the assembly comprises a front fork component (2), which is provided with a shank portion (18), which forms axially acting thrust stops (17, 19a) engaging the upper and lower ends respectively of the steering hub, one of the thrust stops being formed by outwards pointing spring pawls (19) adapted to directly or indirectly cam into the corresponding end portion of the steering hub by snap action when the shank portion is being inserted into the steering hub.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
Assembly of prefabricated bicycle components comprising a frame member component having a sleeve-shaped steering hub, a front fork component provided with a sleeve portion, upper and lower thrust stops formed on said sleeve portion engaging the upper and lower ends respectively of the steering hub, the upper thrust stop being formed by outwardly pointing spring pawls adapted to cam into the corresponding end portion of the steering hub by snap action when the sleeve portion is being inserted into the steering hub, and the lower thrust stop comprising a lower thrust shoulder on said sleeve portion, a handle bar component provided with a sleeve shank, said sleeve shank having an outer diameter which substantially corresponds to the inner diameter of said sleeve portion of said front fork component, said sleeve shank having spring pawls in its lower portion and a shoulder in its upper portion which cooperate with lower and upper counter-stops respectively of said sleeve portion of said front fork component.
Claim 2
Dependent Claim
162 words
Assembly of prefabricated bicycle components comprising a frame member component having a sleeve-shaped steering hub, a front fork component provided with a sleeve portion, upper and lower thrust stops formed on said sleeve portion engaging the upper and lower ends respectively of the steering hub, the upper thrust stop being formed by outwardly pointing spring pawls adapted to cam into the corresponding end portion of the steering hub by snap action when the sleeve portion is being inserted into the steering hub, and the lower thrust stop comprising a lower thrust shoulder on said sleeve portion, a handle bar component provided with a sleeve shank, said sleeve shank having an outer diameter which substantially corresponds to the inner diameter of said sleeve portion of said front fork component, said sleeve shank having spring pawls in its lower portion and a shoulder in its upper portion which cooperate with lower and upper counter-stops respectively of said sleeve portion of said front fork component.
Claim 3
Dependent Claim
58 words
Assembly of prefabricated bicycle components according to claim 1, wherein said sleeve shank of said handle bar component comprises a tube fitting the sleeve portion of said front fork component which also comprises a tube, the pawls of both tubes being shaped by wall material of the tubes between slits extending from the free ends of said tubes.
Claim 4
Dependent Claim
45 words
Assembly of prefabricated bicycle components according to claim 1 or 2, wherein thrust bearings are placed between the ends of said steering hub and said shoulders of said sleeve portion of said front fork component and said sleeve shank of said handle bar component respectively.
