Bicycle carrier fastening bracket

Abstract

A bicycle carrier fastening bracket has a main body, a base, and a leg extending from the base to support a tube defining a hole for receiving a threaded rod having threaded end engaged with a fast releasing nut. The threaded rod also has a head end and associated head end washer, the head end being engaged with a handle capable of eccentric motion. The tube has a slot for receiving an arresting washer, and there is a round hole in the leg. The handle has a grip with a locking hole corresponding in diameter to the round hole. The eccentric body fastening the handle regulates a distance between each of the threaded rod head end washer and the nut and its respective opposite end of the main body. The distance can be shortened to clamp a bicycle front fork when the handle is rotated to rest the grip against the leg, with the locking hole of the grip rested against the leg, so as to facilitate installation of a lock and confine displacement of the grip. The arresting washer, in a normal state with the bicycle front fork unfastened, impedes movement of the threaded rod, thereby preventing the threaded rod from sliding in the tube hole and maintaining each of the distances to enable the bicycle front fork to be fastened.

Description

The invention relates generally to bicycles, and, more particularly, to brackets for fastening bicycles on bicycle carriers.BACKGROUND OF THE INVENTIONConventional bicycle carriers are designed to be mounted on the trunk lid of an automobile, and include means for fastening the front fork of a bicycle to the carrier.Referring to FIG. 1, a prior art bicycle carrier fastening bracket, P, consists of a main body 1 with a tube 12 defining a tube hole 11 for receiving a threaded rod 22 of a fast releasing assembly 20. The fast releasing assembly also consists of a nut 21, a head end 221 of the threaded rod 22 and an associated head end washer 222, and a handle 3 mounted to the head 221, such that each of the nut 21 and the head end washer 222 defines, with the adjacent opposed end 15, 16, respectively, of the main body 1, a distance, H.sub.A and H.sub.B, respectively, by making use of the appropriate engagement of the nut 21 with the threaded rod 22. The handle 3 has an eccentric design ...

AI Technical Summary

Benefits of technology

An objective of the present invention is to provide an improved bicycle carrier fastening bracket consisting of a main body with a slot provided in the tube for accommodating an arresting washer capable of impeding sliding of the fast releasing bolt. The tube body is provided, in the leg, with a round hole for installing a lock. The head of the threaded rod is fastened vertically with an eccentric body of the handle. The handle is thus parallel to the threaded rod and provided with a locking hole. The handle is moved horizontally toward the main body, such that the washer associated with the bolt head and the nut are caused to displace in opposite directions so as to shorten the sum distance between the bolt head washer and the nut with both ends of the main body, thereby to facilitate holding of the bicycle front fork. In the meantime, the locking hole of the handle aligns with the round hole of the main body to facilitate the locating of the lock. The front fork of a bicycle can thus be located easily and securely.

Another objective of the present invention is to provide an improved bicycle carrier fastening bracket. The arresting washer of the present invention is made integrally of a pliable plastic material and provided therein with a rod diametrical shaped and smaller than the fast releasing bolt (threaded rod), and having an outer diameter conforming to the circumferential diameter of the tubular body of the tube for locating securely the bolt, and for effecting the position confining action of the slot of the tube body. As a result, the arresting washer is capable of obstructing the bolt, so as to prevent the bolt from sliding in the tube hole.

Still another objective of the present invention is to provide an improved bicycle carrier fastening bracket with a lock for fastening securely the handle with the main body, so as to prevent the bicycle carrier fastening bracket from being tampered with by an unauthorized person.

Problems solved by technology

Such a readjustment of the distances, H.sub.A and H.sub.B, can cause a great deal of physical hardship and inconvenience.

As a result, the handle 3 is rather vulnerable to interference by an external force, such that the bicycle front fork is no longer secured by the inward movement of the handle 3 to compress the sum distance, H.

In other words, the prior art bicycle carrier fastening bracket is not theft resistant.
