  • Patent number: 12539596
    Abstract: A hydraulic tool storage device positions a hydraulic tool in a manner that prevents damage to seals contained within the tool. The storage device can take the form of a tool stand that provides ready access to the hydraulic tool for mating with equipment that may utilize the tool and provides a stable platform for storage or transport of the hydraulic tool. As an example, such hydraulic tools can include hydraulic hammers.

  • Publication number: 20220161890
    Abstract: An electric pedal-assist bicycle may have a drivetrain including a crankset and an electric motor (e.g., a hub motor). A motor controller of the bicycle is configured to dynamically drive the motor to propel the bicycle based on a plurality of inputs. The inputs include information received from one or more of the following: user-related input(s), vehicle-related sensor(s), environmental sensor(s), and software. For example, the controller may drive the motor based on pedaling cadence and vehicle pitch orientation.

  • Patent number: 8430415
    Abstract: A bicycle rear suspension system is connected between front and rear triangles. The suspension system includes an eccentric bearing unit disposed within one of the front and rear triangles, a connecting member connected pivotally to the other one of the front and rear triangles, and a pivot. The eccentric bearing unit includes an outer bearing, and an inner bearing movable within the outer bearing along an annular path. The pivot extends through the inner bearing of the eccentric bearing unit and into the connecting member such that, application of a force to the rear triangle results in pivoting movement of the rear triangle relative to the front triangle, and movement of the inner bearing along the annular path.

  • Publication number: 20120214629
    Abstract: A bicycle sprocket includes a sprocket body having a plurality of bottom edges along an outer periphery thereof, and a plurality of teeth. The bottom edges extends in a generally circumferential direction of the sprocket body. Each of the bottom edges is connected between two adjacent ones of the teeth. The central points of the bottom edges includes a first group of central points each spaced apart from the center of the sprocket body by a first distance, and a second group of central points each spaced apart from the center of the sprocket body by a second distance smaller than the first distance. The sprocket body further has a direction guiding groove extending inwardly from the outer periphery, permitting passage of a chain pin, and adjacent to the first group of the central points.

  • Publication number: 20110312456
    Abstract: A bicycle sprocket comprises a sprocket body and a plurality of angularly equidistant teeth extending radially and outwardly from an outer periphery of the sprocket body. The sprocket body has a plurality of bottom edges along the outer periphery. The bottom edges extend in a generally circumferential direction of the sprocket body. Each of the bottom edges is connected between two adjacent ones of the teeth. The central points of the bottom edges include at least first and second groups of the central points. Each of the first group of the central points is spaced apart from the center of the sprocket body by a first distance. Each of the second group of the central points is spaced apart from the center of the sprocket body by a second distance that is smaller than the first distance. The difference between the first and second distances is smaller than 2 mm.

  • Patent number: 8033558
    Abstract: A bicycle rear suspension system includes a front part including a top tube, a down tube, a head tube and a seat tube. A rear part of the bicycle rear suspension system includes two seat stays and two chain stays. The seat stays have first ends pivotally connected to the dropouts on the first ends of the chain stays and two second ends pivotally connected to a first end of a connection member at a first pivot point. Two second ends of the chain stays are pivotally connected to a bridge between the down tube and the seat tube. A second end of the connection member is pivotally connected to the top tube. A cylinder has a first end pivotally connected to the bridge and a second end pivotally connected to a mediate portion of the connection member at a second pivot point.

  • Patent number: 7909347
    Abstract: A bicycle rear suspension system that includes a main frame and a rear wheel suspension system, the main frame generally is comprised of a seat tube, a down tube, a top tube, and a head tube. The rear wheel suspension system consists of a first linkage member, a rear wheel swingarm, and a second linkage member. The rear wheel suspension system allows for a preferential linear decrease in rate of chainstay lengthening combined with a preferential linear decrease in rate of acceleration anti-squat with the value of 100% anti-squat occurring at the statically weighted sag point.

  • Publication number: 20100007113
    Abstract: A rear suspension system for bicycles includes a front triangle, a rear triangle and a shock absorbing unit pivotably connected between the front and rear triangles to allow the rear triangle to move at a regulated rate with regard to the front triangle. The seatstays of the rear triangle have two dropouts and two extension portions on two opposite ends thereof. The two dropouts each have a notch for engaging with a rear wheel shaft. The extension portions are pivotably connected to the shock absorbing unit and the front triangle. The chainstays have two respectively first ends thereof pivotably to the dropouts at two pivot points and two respective second ends pivotably connected to the seat tube. The pivot points are located above or on a line between a center of the bottom bracket and a center of the notches in the dropouts.
