The priming system includes a force-preparation assembly adapted to selectively arrange the drive assembly to provide the drive force to the injectate assembly. In some embodiments, the priming system includes a locking assembly adapted to releasably retain the injectate assembly relative to the body. In some embodiments, the priming system includes a dosing assembly adapted to selectively draw a volume of liquid into the injectate assembly. | 06-18-2009 |
20100076374 | INJECTION DEVICE PLUNGER AUTO-DISABLE - A nozzle assembly for a needle-free injection device. The nozzle assembly includes a nozzle body including an injectate chamber and one or more outlet orifices and a plunger configured to move through the injectate chamber toward the one or more outlet orifices. In some embodiments, the plunger includes a first portion and a second portion removably joined by a frangible region. In some embodiments, the plunger includes extensions configured to couple the plunger to a drive assembly of a needle-free injection device. | 03-25-2010 |
20100123295 | Skateboard - A skateboard is provided with a deck providing a support platform for the user, a front and rear wheel sets and trucks coupled to the deck. The support platform may include a central portion and raised front and rear portions. The front and rear portions may angle upwardly from the central portion, and then angle downwardly. The trucks may be coupled to the deck at the downwardly angled portions. The front and rear trucks may each include a pair of torsion springs alongside a kingpin. A foot-operated brake may be mounted to the rear portion of the support platform. The deck may include a hinged portion located between the front and rear portions with a handle located in the hinged portion of the deck. | 05-20-2010 |
20110042913 | SKATEBOARD - A skateboard is provided with a deck providing a support platform for the user, a front and rear wheel sets and trucks coupled to the deck. The support platform may include a central portion and raised front and rear portions. The front and rear portions may angle upwardly from the central portion, and then angle downwardly. The trucks may be coupled to the deck at the downwardly angled portions. The front and rear trucks may each include a pair of torsion springs alongside a kingpin. The hardness of the torsion springs may be varied to alter the performance of the skateboard depending on the characteristics of the user. A foot-operated brake may be mounted to the rear portion of the support platform. The deck may include a hinged portion located between the front and rear portions with a handle located in the hinged portion of the deck. The torsion springs may be provided with an identifier based upon their hardness. In certain examples that identifier may be a color coding system. | 02-24-2011 |
20120319373 | KICK SCOOTER - Embodiments herein provide a kick scooter comprising of 4 main assemblies: a center deck, a front wheel assembly, a rear wheel assembly, and a handle assembly, where these 4 assemblies have means to be easily and quickly separated from, and attached to, each other. The scooter allows the user to collapse the whole scooter into a compact volume so that it can be carried in a small backpack and be able to be reassembled for use in a few seconds and without any tools. | 12-20-2012 |
20140216205 | Crank Assembly - The invention is a crank assembly designed to allow the length of the crank arms to vary throughout the revolution of the crank. A spindle is attached to the bottom bracket assembly of a bicycle. The spindle is comprised of a cylindrical shaft with a mating feature at each end. A first crank arm assembly is attached to the spindle's left mating feature. The left crank arm assembly includes the crank arm, slider assembly, bearing, track, and pedal. Next, a second crank arm assembly is attached to the spindle's right mating feature. The right crank arm assembly includes the chain ring base, bearing, track, crank arm, slider assembly, pedal, and chain ring. Finally, the trajectory of the pedals in this invention follows a unique curve designed to allow the optimum expansion and contraction of the crank arms coinciding with the optimum amount of torque and angular speed. | 08-07-2014 |
20140217695 | Crank Assembly - This invention provides a novel solution for an optimally powered crank for a human-powered vehicle, such as a bicycle. This invention includes a novel system and method to optimize the length of each crank arm throughout the revolution of the crank assembly. First, a crank arm assembly is attached to the bicycle's existing spindle assembly. The crank arm assembly includes a rail section that is fixed at one end to the mounting section of the crank arm assembly. Next, the opposite end of the rail section is attached to the sliding section of the crank arm assembly. The sliding section of the crank arm assembly also includes a feature that allows the sliding section to collapse and expand along the rail section. The crank arm assembly also includes at least two track rollers mounted to the side of each sliding section designed to reduce friction and counter inertial forces associated with the crank arm assembly sliding along the tracks. Next, the assembly includes two tracks mounted on each side of the frame. The tracks are used to control the length of the crank arms at each angular position. Finally, the shape of each track is designed to coincide with the optimum crank arm length at the various angular positions as the crank arm rotates through a complete revolution. | 08-07-2014 |
