Patent number: 5988741Abstract: A lightweight, high strength bicycle seat post for securing a bicycle seat to a seat tube of a bicycle frame. It comprises a hollow metal tubular member having a seat tube portion for reception in and securement to the seat tube of a bicycle frame, and an integral head portion comprised of four planar walls diverging in an upward direction to form an open space. A pair of the sidewalls are oriented in a fore and aft direction to the fore and aft direction of the bicycle seat and a pair of end walls which are transverse to the fore and aft direction and connects the fore and aft ends of the pair of sidewalls together defining the open space, which, preferably, is generally rectangular. The upper edges of the sidewalls have arcuate load reacting edges, which define a seat angle adjustment path, and a clamp assembly secures the bicycle seat to the load reacting edges so that the seat loads are transferred directly to the load reacting edges at any seat angle.Type: GrantFiled: April 17, 1995Date of Patent: November 23, 1999Inventors: Darrell W.

Patent number: 5692764Abstract: The invention disclosed herein is a very durable, lightweight, front fork assembly for use on competition bicycles. The invention provides improved fatigue and impact resistance compared to prior art designs. The invention makes maximum use of advanced, high strength composite materials and high strength, lightweight metal alloys, improving its stiffness-to-weight and strength-to-weight ratios. The superior structural performance of the invention is provided by a unique section geometry and ply configuration that efficiently utilizes the material to maximize bending and torsional stiffness while minimizing weight. The improved strength also comes from the superior control of the molding process, made possible with a removable pressure bladder that remains connected to the pressure source, and is regulated, during the molding process.Type: GrantFiled: August 13, 1993Date of Patent: December 2, 1997Assignee: Klein Bicycle CorporationInventors: Gary G.

Patent number: 5626355Abstract: This invention relates to front fork, telescoping type suspension systems for bicycles. The main focus of the invention is the brake bridge assembly, the fork crown assembly and the joinder of these assemblies to form the fork suspension. The brake bridge assembly serves two main functions: 1) it provides a stiff structural connection between the right and left telescoping struts, to reduce wheel wobble during high speed wheel impacts, and 2) it provides a structural support for the brake cable stop. The invention provides for increased stiffness and lower stresses in the brake bridge, which translates into improved directional stability for the front wheel, less displacement for the brake cable stop .(when the brake loads are applied) and improved fatigue life for the assembly. It also provides for a simpler and less expensive means for mounting the brake bridge to the fork assembly. The invention also encompasses the fork crown producing a lightweight structure with high torsional and bending rigidity.Type: GrantFiled: April 1, 1994Date of Patent: May 6, 1997Inventors: Darrell W. Voss, Gary G. Klein

Patent number: 5517878Abstract: A lightweight handlebar/steerer locking mechanism for use on road and mountain bicycles. The invention provides higher fatigue and impact resistance, lower material and production costs, and improved adjustability, compared to prior art designs, all at a reduced weight.The superior structural performance of the invention is provided by a unique, 3-dimensional, sliding, compression wedge. The 3-dimension wedge improves the stress distributions within the device my introducing a more uniform wedging (locking) action on the circumference of the steerer tube. This allows the mating parts to be designed lighter, thereby reducing the total weight of the assembly. The configuration of the design also lends itself to modern metal working methods. This further improves the strength of the parts by increasing the material allowables. Also, these metal working operations help to reduce material scrap, thus reducing material costs.Type: GrantFiled: August 13, 1993Date of Patent: May 21, 1996Assignee: Klein Bicycle CorporationInventors: Gary G. Klein, Darrell W. Voss
