Patent number: 5924328Abstract: The braking device of the present invention is equipped with a resistance element which acts so that, when the brake device is operated by pulling a brake lever to a set operating position where the wheel braking force produced by brake shoes reaches a certain set value, a discretely increased force resists operation of the brake lever so that further operation of said brake lever is inhibited until a pulling force which is greater than the resistance force is thereafter applied to the brake lever.Type: GrantFiled: July 25, 1997Date of Patent: July 20, 1999Assignee: Shimano, Inc.Inventors: Shinpei Okajima, Masanori Sugimoto, Kazuhisa Yamashita

Patent number: 5857932Abstract: A cable operated control device includes a movable control member, a frame coupled to the movable control member, and a cable guide member mounted to the frame for rotation around a guide member axis. The cable guide member includes a curved outer peripheral cable guide surface disposed radially outwardly from the guide member axis for guiding the cable. A bearing having a cable guide surface is disposed radially outwardly from the outer peripheral cable guide surface. When the cable guide member has a small radius of curvature, the cable may contact the bearing and thus avoid the excessive friction encountered in the prior art.Type: GrantFiled: May 14, 1997Date of Patent: January 12, 1999Assignee: Shimano, Inc.Inventor: Masanori Sugimoto

Patent number: 5850761Abstract: An attachment assembly for a bicycle handle bar provides an extension bar as well as a brake operating device therefor. The extension bar, together with the handle bar, provides a pair of gripping portions, while the brake operating device provides a pair of hand portions for operating a brake. The brake operating device is coupled to the free end of the extension bar and provides a pair of hand portions such that the rider can grasp the first hand portion from the extension bar and the second hand portion from the grip portion formed on the primary handle bar. In a first embodiment, the brake operating device is integrally formed as a one-piece, unitary member with a part of the extension bar, while in another embodiment, the brake operating device is formed as a separate unit which is releasably coupled to the extension bar.Type: GrantFiled: December 17, 1996Date of Patent: December 22, 1998Assignee: Shimano Inc.Inventor: Masanori Sugimoto

Patent number: 5809840Abstract: A cap is provided for fitting to a bicycle control cable of the type having an inner cable sliding disposed within an outer casing, where the outer casing terminates for exposing a portion of the inner cable. The cap has a first section defining a first section opening for fitting the outer casing therein. A protective cover extends along the exposed portion of the inner cable and has a first end disposed over the cap.Type: GrantFiled: February 13, 1996Date of Patent: September 22, 1998Assignee: Shimano, Inc.Inventors: Hiromi Oda, Shinpei Okajima, Masanori Sugimoto

Patent number: 5655630Abstract: A brake mechanism includes a brake arm having a lower portion for being pivotally mounted to the bicycle and a link member having an upper portion and a lower portion. A shoe attachment member for attaching a brake shoe is coupled to an upper portion of the brake arm and to an upper portion of the link member. The lower portion of the brake arm and the lower portion of the link member are adapted to be pivotally mounted to the bicycle so that the shoe attachment member maintains a generally horizontal attitude when the brake arm pivots relative to the bicycle.Type: GrantFiled: August 24, 1995Date of Patent: August 12, 1997Assignee: Shimano, Inc.Inventor: Masanori Sugimoto

Patent number: 5636716Abstract: Each brake mechanism for a bicycle includes a brake arm having an upper portion and a lower portion, a link member having an upper portion and a lower portion, and a shoe attachment member for attaching a brake shoe thereto. The shoe attachment member is pivotally coupled to the upper portion of the brake arm and to the upper portion of the link member. The lower portion of the brake arm and the lower portion of the link member are adapted to be pivotally mounted to the bicycle so that the lower portion of the brake arm and the lower portion of the link member pivot when a braking force is applied by the cantilever brake apparatus to cause the brake shoe to move toward a wheel rim. The lower portion of the brake arm and the lower portion of the link member are spaced apart from each other for forming a four-bar link mechanism with the shoe attachment member.Type: GrantFiled: March 6, 1996Date of Patent: June 10, 1997Assignee: Shimano, Inc.Inventors: Masanori Sugimoto, Toshiyuki Tanaka

Patent number: 5537891Abstract: A bicycle brake lever mechanism having a bracket mountable to a bicycle handlebar, a lever mounted for pivotal movement to the bracket and a brake cable connector connected to the lever. The cable connector is connected to the lever via an adjusting mechanism for so that the return position of the brake lever relative to a lever bracket may be adjusted to accommodate various sized hands. Further, the adjusting mechanism allows for adjustment of a lever ratio A which is defined mathematically by the distance between the pivot point of the lever and the pivot point of the cable connector on the lever divided by the distance from a set point on the brake lever to the pivot point of the lever.Type: GrantFiled: July 19, 1994Date of Patent: July 23, 1996Assignee: Shimano Inc.Inventors: Masashi Nagano, Kazuhisa Yamashita, Yuji Nakashima, Masanori Sugimoto

Patent number: 5515946Abstract: A brake unit for a bicycle pivotably attached to brake brackets each having a support shaft (12a) projecting sideways and a radial seat surface formed in a proximal region of the support shaft. The brake unit comprises brake calipers (4) each including a boss (4a) having a boss bore for receiving the support shaft, a first end surface (4b) extending radially, and a second end surface (4c) disposed axially opposite from the first end surface. Each brake caliper is secured to the support shaft by a stud bolt (14) having a contact surface (15a) extending radially. A bush (13) is mounted between an inner peripheral surface of the boss bore and an outer peripheral surface of the support shaft. The first end surface of the brake caliper and the radial seat surface inhibit the brake caliper from moving in one axial direction. The contact surface of the stud bolt and the second end surface inhibit the brake caliper from moving in the other axial direction.Type: GrantFiled: February 15, 1995Date of Patent: May 14, 1996Assignee: Shimano, Inc.Inventors: Masanori Sugimoto, Tsuyoshi Sakashita
