| 20090104059 | AIR PUMP HAVING SELECTABLE LOW PRESSURE AND HIGH PRESSURE MODE - An air pump, including: two cylinders, a big one and a small one, is fitted to each other by a contractible way. A head connects with the out end of the small cylinder. A pressure relief valve connects with the out end of the big cylinder. A first piston is fixed at the in end of the small cylinder and placed in the big cylinder. A first pipe, one end fixes on the out end of the big cylinder, and the other passes through the first piston and places inside the small cylinder. A first chamber with a passage communicating with the first pipe forms therein between the inside wall of the big cylinder and the outside wall of the first pipe. A second pipe, one end fixes at the out end of the small cylinder and communicates with the head in one-way air admission and the other fits into the first pipe by contractible way and communicates with it. A second piston, which is placed inside the small cylinder, fixes at the other end of the first pipe and the second pipe goes through it. A second chamber with a one-way passage communicating with the head forms therein between the inside wall of the small cylinder and the outside wall of the second pipe and between the out end of the small cylinder and the second piston. | 04-23-2009 |
| 20100035736 | ADJUSTABLE DUMBBELL SYSTEM - A dumbbell is described including a handle having a grip and at least one end, an inner plate mounted on the handle adjacent the grip, in a fixed rotational orientation, a support plate rotationally mounted on the handle adjacent the inner plate, at least one collar rotationally mounted on the handle adjacent the support plate, and rotationally fixed with the support plate, a selector knob rotationally mounted on the handle adjacent the at least one collar, and rotationally fixed with the collar, a weight plate removably mounted on the handle adjacent the at least one collar, and a means for selectively securing the support plate to the inner plate to resist the rotation of the support plate, collar and selector knob with respect to the inner plate and handle. | 02-11-2010 |
| 20100313623 | METHOD FOR MAKING BICYCLE PEDAL - Disclosed is a method for making a bicycle pedal, comprising the following steps: (A) cutting, in which an elongate metal plate is formed by pressing and two coupling holes are formed through the plate; (B) bending, in which the metal plate is bent to have the opposite ends jointed to each other, forming a circumferentially enclosed hollow pedal frame with the two coupling holes concentrically located and spaced from and opposing each other; and (C) welding, in which a collar is mounted outside the pedal frame concentric with respect to each of the coupling holes through welding to provide a sufficient contact area for rotatably receiving and supporting a spindle therein, whereby the pedal frame is rotatable about the spindle for pedaling operation of a bicycle. This method overcomes the various drawbacks occurring in metal-cast or plastic injection-molded bicycle pedals, providing economic advantages for high-mix low-volume productions. | 12-16-2010 |
| 20110003668 | ADJUSTABLE DUMBBELL SYSTEM - A dumbbell is described including a handle having a grip and at least one end, an inner plate mounted on the handle adjacent the grip, in a fixed rotational orientation, a support plate rotationally mounted on the handle adjacent the inner plate, at least one collar rotationally mounted on the handle adjacent the support plate, and rotationally fixed with the support plate, a selector knob rotationally mounted on the handle adjacent the at least one collar, and rotationally fixed with the collar, a weight plate removably mounted on the handle adjacent the at least one collar, and a means for selectively securing the support plate to the inner plate to resist the rotation of the support plate, collar and selector knob with respect to the inner plate and handle. | 01-06-2011 |

| 20080236675 | Air valve connecting device for connecting different valves - An air valve connecting device includes a mouth attached to one end of a housing and having a compartment for engaging with a U.S. type valve, and having a bore for engaging with a French type valve, a barrel engaged onto the mouth, an actuator engaged in the housing and having a shank for engaging with the barrel for selectively receiving the French type valve, a tube engaged in the actuator for engaging with the French type valve, and the tube is extendible into the mouth for selectively engaging with the U.S. type valve, a handle includes a cam member for forcing the actuator to secure either the French type valve or the tube to the actuator, and for forcing the barrel and the mouth to engage with either the French type valve or the U.S. type valve. | 10-02-2008 |
| 20090124473 | Table for tilting inversion exerciser - A tilting inversion exerciser includes a lower supporting stand having an axle, and a table rotatably supported on the stand with the axle, the table is made of plastic material and having a resilient one-integral-piece structure for smoothly engaging with the back portion of the user and for comfortably supporting the user, and for easily sterilizing purposes particularly following use by someone just finishing a workout and very sweaty. The table is pivotally supported on a base with a frame and one or more arms in which the arms are pivotally supported on the base and limited to pivot or to rotate relative to the base. | 05-14-2009 |
| 20100279838 | Angle adjusting mechanism for tilting inversion exerciser - A tilting inversion exerciser includes a supporting stand having a plate formed in each of two housings, and a curved channel formed in each plate and formed by two end stops, two arms each having a board formed in a casing and pivotally coupled to the plate with a pivot axle for supporting a user supporting table, the board includes a guide pin slidably engaged in the curved channel of the plate, a panel includes an anchor engageable into the curved channel of the plate for forming a shortened moving path between the anchor of the panel and the end stop of the plate, and for limiting the guide pin of the board to slide along the shortened moving path, and a latch member changeably secures the anchor and the panel to the housing at different angular position. | 11-04-2010 |
