Quick Release Stem
View pageUS Patent:
8152190, Apr 10, 2012
Filed:
Feb 11, 2010
Appl. No.:
12/704370
Inventors:
Alejandro Lacreu - New York NY, US
International Classification:
B62K 21/22
US Classification:
280279, 745511, 745513
Abstract:
A stem connecting the handlebars and steerable fork of a cycle has one tube attached to the handlebars and another tube attached to the steerable fork with the tubes capable of being rotated and locked with respect to one another. This arrangement allows for various configurations of the handlebars and fork including the typical riding configuration as well as an alternate configuration where the handlebars are folded with respect to the fork. Change in configuration is accomplished without tools by way of a biased locking arrangement for the tubes.
Constant Torque Variable Speed Drive Train

20080146390, Jun 19, 2008
Filed:
Dec 19, 2006
Appl. No.:
11/642309
Inventors:
Alejandro Lacreu - New York NY, US
International Classification:
F16H 7/00
F16H 29/04
F16H 29/04
US Classification:
474 68, 474 80
Abstract:
A drive train system for human powered vehicles whereby the pedals move in a linear or slightly curved path, providing a superior ergonomic ride. Power is transmitted from the pedals by a flexible drive tension transmitting component to two one way locking continuous variable radius helicoids mounted on a shaft by means of a one way locking mechanism. The pedals move alternatively back and forth pulling the cables and unwinding (active phase) their corresponding helicoids and thus transferring spinning motion to the shaft. The helicoids act as a set of sprockets of continuous variable radius optimizing the ergonomic delivery of leg power to the shaft. A step-less shifting system alters the length of cable wound in the helicoids and can manually select the “zone” of the helicoids utilized for optimal power transmission. This gearing system can manually adjust the power-speed ratio according to the environment demands, akin to a gear system.
