Patent number: 4723462Abstract: An arrangement whereby the resisting force tending to oppose the shifting of a lever is roughly constant, irrespective of the direction in which the lever is shifted. For this purpose, the lever 1 is roughly freely rotatively mounted on its support 4 and an intermediate ring 7 is provided and frictionally mounted relative to the support, the lever 1 defining a cavity 18 which opens onto the outer surface of the ring 7 and in which is received an element 19 for achieving a coupling between the lever and the ring. The cavity defines a cam surface which is so oriented as to achieve a unidirectional coupling by a wedging of the coupling element between the lever and the ring.Type: GrantFiled: August 28, 1986Date of Patent: February 9, 1988Assignee: Huret et ses FilsInventor: Maurice Coue

Patent number: 4676118Abstract: The invention relates to a gear-change device for derailleurs or gear-change hubs in which by enlargement of at least one of the provided detents in the circumferential direction and by arrangement of a spring which biases the change lever in the one direction an easy adjustability is provided by an adjusting screw. Furthermore the exchanging of detent discs for easy adaptation to different gear ratio numbers is easily possible. The assembly of the gear changer is easy to effect in as much as two component groups can be prefitted independently of one another. A shift-over device for one direction, as utilized advantageously especially in derailleurs, can easily be integrated.Type: GrantFiled: October 18, 1985Date of Patent: June 30, 1987Assignee: Ets.

Patent number: 4624151Abstract: A cycle accessory, for example a double lever 2, 3 for controlling a derailleur, is carried by a support 4 defining a fixing tab 11 received and wedged in a cavity of complementary shape which may be defined by a part 1 of the frame and a bridge member 14 brazed on the frame. The arrangement is such that, when a force is exerted on the accessory in the course of use, this force tends to increase the wedging between the fixing tab 11 and the cavity. Applicable to any accessory for a cycle.Type: GrantFiled: June 26, 1984Date of Patent: November 25, 1986Assignee: Huret et ses FilsInventor: Gerard Huret

Patent number: 4543078Abstract: A fork element 1 for guiding the chain is pivotally mounted by means of a deformable parallelogram structure 11, 12 on a support constituted by an arm 3 which is upwardly and outwardly inclined relative to a vertical plane containing the longitudinal axis of the bicycle. The parallelogram structure is deformed in a plane which is inclined in a direction parallel to said arm. With this arrangement, the fork element is shifted in a constant vertical position in a combined oblique upward and advancing movement so as to shift the chain from a small chain wheel to a larger chain wheel.Type: GrantFiled: September 6, 1983Date of Patent: September 24, 1985Assignee: Huret et ses FilsInventor: Maurice E. L. Coue

Patent number: 4535644Abstract: The invention simplifies the manufacture of levers employed in particular for actuating cycle derailleurs and facilitates the mounting of the cable on these levers. For this purpose, the lever 20 has at least one cavity 31 in which the cable can be engaged resiliently in opposition to the action of a retaining device.Type: GrantFiled: December 29, 1983Date of Patent: August 20, 1985Assignee: Huret et ses FilsInventor: Maurice E. L. Coue

Patent number: 4534238Abstract: The unit comprises a collar defining a bearing surface (13) for the lever, a fixing device such as a rivet (24) which also constitutes the journal on which the lever (25) is mounted, and an elastically yieldable washer (23). The collar defines also a cavity (16) for a member constituting an abutment for a cable sheath and may be provided with a rapid fixing device.Type: GrantFiled: December 23, 1982Date of Patent: August 13, 1985Assignee: Huret et ses FilsInventor: Maurice E. L. Coue
-
Patent number: 4529395Abstract: The derailleur comprises, between the conventional articulation mechanism which allows the lateral displacement of the chain guide device (12), an additional articulation mechanism (10, 11) whereby the chain guide device (12) can effect a displacement which is substantially free and of large extent in a plane perpendicular to the axis (X--X) of the crank-gear. This very substantially improves the conditions under which the chain is shifted from one chain wheel to another.Type: GrantFiled: December 20, 1982Date of Patent: July 16, 1985Assignee: Huret et ses FilsInventor: Maurice E. L. Coue

Patent number: 4516961Abstract: The derailleur comprises a chain guiding and shifting device in the form of a fork member (2) articulated to a support (1) adapted to be fixed to the frame of the bicycle. At least one (4) of the wings of the fork member (2) has a part (11) which is adjustable in position so as to adapt the width of the at least one wing (4) to the diameter of the small chain wheel of the crank-gear.Type: GrantFiled: December 23, 1982Date of Patent: May 14, 1985Assignee: Huret et ses FilsInventor: Maurice E.

Patent number: 4517450Abstract: The detecting device comprises an L-shaped support bracket 1 having a branch 2 on which is rotatively mounted a disc 4 engaged with the rotary element and a second branch 3 which carries a member constituting a bearing for a motion take-off head 19 of a transmission cable 20 or the like. Counter transmission and speed changing means 8 are provided between the disc 4 and the motion take-off head 19. The support 1 and the member 16 constituting a bearing are adapted to be capable of occupying a plurality of different relative positions. A set of counter transmission speed changing means corresponding to the various relative positions of the support and the member constituting a bearing is provided. In this way this detecting device is very easily adaptable to wheels having different diameters.Type: GrantFiled: May 3, 1983Date of Patent: May 14, 1985Assignee: Huret et ses FilsInventor: Maurice Coue

Patent number: 4494944Abstract: The derailleur is shown in a retracted position allowing the dismantling of the rear wheel of the cycle. In this retracted position, it is maintained by an abutment which is rigid with the fixed part of the derailleur and is resiliently retained in a cavity defined by the concavity of a resiliently yieldable strip carried by a member fixed to the frame lug. In the operative position, the abutment is applied against the support surface of the lug.Type: GrantFiled: June 28, 1982Date of Patent: January 22, 1985Assignee: Huret et ses FilsInventor: Maurice E.

Patent number: 4493489Abstract: The fixing device is cheap and facilitates the mounting of the derailleur on the frame lug. This is achieved in providing on the support of the derailleur a wedging device which is rotatably mounted on the support with a high degree of friction and is adapted to cooperate with the frame lug. The support further comprises preferably an elastically yieldable device which is capable of clipping in the slot of the frame lug so as to center the support.Type: GrantFiled: March 17, 1982Date of Patent: January 15, 1985Assignee: Huret et ses FilsInventors: Roger Huret, deceased, by Alain P.

Patent number: 4486182Abstract: The invention provides a mechanism which is simpler in construction, cheaper and easier to assemble. The derailleur mechanism is of the type comprising a movable device for guiding or shifting the chain connected to a support in such manner as to be displaced in translation with respect to the support by means of an actuating device. The movable device is connected to the support, on one hand, by a link and, on the other hand, by a pin-and-slot connection. The slot has the shape of an arc of a circle whose radius is equal to the distance between the two pivot pins of the link.Type: GrantFiled: June 14, 1982Date of Patent: December 4, 1984Assignee: Huret et ses FilsInventor: Maurice E.
