20110305502 | POSITIONING SWITCH MECHANISM FOR FOLDABLE ASSEMBLY OF BICYCLES - The present invention relates to a positioning switch mechanism for foldable assembly of bicycles, comprising a positioning switch assembly, a first rotary member and a second rotary member which are able to revolve against each other along a rotation axis. The positioning switch assembly has a press button assembly set in the first rotary member with a spring and a pin set in the second rotary member with a spring as well. When the first rotary member revolves close to overlap against the second rotary member, the first rotary member pushes the pin to be drowned back into the second rotary member. The first rotary member continues to revolve against the second rotary member till they are completely overlapped. The pin limits itself in the first rotary member so as to fix with the second rotary member. When the press button assembly takes pressure from the user, it pushes the limit portion to be drowned back into the second rotary member so that the positioning switch assembly is in an unlocked state and the first rotary member is capable of revolving against the second rotary member. | 12-15-2011 |
20130237390 | ADJUSTABLE WEIGHT ASSSEMBLY FOR WEIGHT TRAINING MACHINE - An adjustable weight assembly includes a weight device and an adjustment device. The weight device includes a rail, a movable member and multiple weights. The movable member is connected to a rod and receives a force applied by a force applying unit so as to move along the rail. The rod has multiple through holes and each weight has a latitude hole and a longitudinal hole. Each latitude hole has a pin extending therethrough and the rod extends through the longitudinal holes. The adjustable device includes a driving unit, a movable part and multiple pivotal members. The driving unit drives the movable part and each weight is pivotably connected to one of the pivotal members. When the movable part moves along the rail, the pivotal member is pivoted to decide the engagement between the pin and the through hole so that the user can adjust the number of the weights. | 09-12-2013 |
20140042725 | FRAME OF BICYCLE - A bicycle frame includes a seat tube, two chain stays and a down tube connected to the seat tube. A seat post is inserted into the seat tube and has a seat connected thereto. The chain stays is connected to a rear wheel and a head tube is connected to the down tube. A front fork is connected to the head tube. A tubular body is connected to the bicycle frame and the wall of the tubular body has a first slot. The seat tube is connected to a slide which is connected to the wall of the tubular body. A pin extends through the slide and the first slot. A first securing member and a second securing member are connected to two ends of the pin. The first and second securing members connect the wall of the tubular body to the slide. | 02-13-2014 |
20140148312 | SWING EXERCISER - A swing exerciser includes a base and a frame is pivotably connected to the base by a shaft. An exerciser such as a stationary bike is connected on the frame. A returning device includes a resilient bar which has a first end fixed to the base, and a second end fixed to the frame. The frame swings about the shaft and from a balanced position to an inclined position. The resilient bar is bent and the first and second ends of the resilient bar generate a returning force to pivot the frame from the inclined position to the balanced position. | 05-29-2014 |
20150018173 | ELLIPSE EXERCISER WITH INCLINATION ADJUSTMENT UNIT - An ellipse exerciser includes a base, a rail frame having two rails, an ellipse unit having two pedals and two roller units, and an adjustment unit having a bottom part and a support frame. The roller units are moved along the rails of the rail frame. The bottom part has two slots and each slot has teeth. Two guide boards are pivotably connected to the two respective outsides of the bottom part. Each guide board is connected with a spring. The support frame has a rod and two ends of the rod are respectively engaged with the slots. The guide boards each have a stop portion to guide the rods. When the support frame is rotated to different angular positions relative to the bottom part, the rods are engaged with different teeth so as to adjust the inclination of the rails. | 01-15-2015 |
20150335941 | Treadmill - A treadmill includes a base, a platform, a universal joint, two elevators and two telescopic elements. The universal joint is used to connect a rear portion of the base to a rear portion of the platform. Each of the elevators includes a post supported on a front portion of the base and a carriage movably supported on the post. Each of the telescopic elements includes an end connected to a front portion of the platform and another end connected to the carriage of a corresponding one of the elevators. | 11-26-2015 |
