Patent number: 10857419Abstract: The invention relates to the field of sports and medicine, specifically to training devices, more particularly to an elliptical exercise device suitable for simultaneous training of shoulder and pelvic girdle muscles in a human. Accordingly, it is desirable to provide an exercise device for training trunk muscles, the shoulder girdle and the pelvic girdle in a human and, at the same time, to enable simulation of various motion patterns by activating different groups of muscles, joints, the locomotor system in a human in general and especially muscles which hold the vertebral spine. It is further desirable to enable optional correction of their load during the process of coordination of motor activity (locomotion) of the human body through simultaneous elliptical motions of hands and feet, which, in addition to the load on the shoulder girdle and the pelvic girdle muscles, simultaneously provide preferably stretching load on muscle groups which hold the vertebral spine.Type: GrantFiled: December 21, 2016Date of Patent: December 8, 2020Assignee: TIGERSTEP FITNESS SEInventors: Sergii Anatoliyovich Solodovnik, Oleg Vietrov

Patent number: 8556628Abstract: The invention is a trigger pull training device for improving trigger pull technique. The device has a frame with a trigger track opening and a trigger which goes through that opening. A proximity sensor or a plurality of proximity sensors are placed proximate the trigger track opening. The sensors are connected to an indicator whereby pulling the trigger such that the trigger is within the sensing zone causes the proximity sensor to emit a signal. A plurality of sensors can be lined along the trigger track opening to indicate the accuracy of any pull.Type: GrantFiled: August 15, 2006Date of Patent: October 15, 2013Inventor: Malcom E. Baxter

Patent number: 8083651Abstract: An exercise machine includes a frame, a saddle, at least one crank arm, at least one pedal, a force measurement, an angle detector, a processor, and an adjustment mechanism. The saddle is connected to the frame. The crank arm is pivotally connected to the frame, and the pedal is pivotally connected to the crank arm. The force measurement measures a force applied to the crank arm, and the angle detector detects a crank arm angle. The processor is programmed to calculating a work value according to the force and the crank arm angle. The feedback mechanism returns the work value to a user.Type: GrantFiled: March 25, 2010Date of Patent: December 27, 2011Inventor: Tung-Wu Lu

Patent number: 7806006Abstract: Strain gauges are mounted on each crank arm of the bicycle and provide a measure of the torque applied to each crank arm. In a preferred embodiment, strain gauges are mounted on opposite edges of each crank arm, which includes a self-contained power, electrical circuitry, and a wireless transmitter for transmitting the strain measurement information to a main controller. The main controller includes a wireless transceiver for transmitting and receiving data from both the left and right crank arms and external devices. Memory is also included for storing such data for subsequent analysis to determine the individual leg performance of a cyclist during a race or training session.Type: GrantFiled: November 8, 2007Date of Patent: October 5, 2010Assignee: Grand Valley State UniversityInventors: Robert Ryan Phillips, Coty W.

Patent number: 7399259Abstract: An Elevating Exercise Bicycle for fitness and amusement ride in one having occupant-seating station with frame attached to a support base frame through an articulating member providing angular rotation about lower pivot pins to create constant pitching angle and vertical movement for occupant-seating station. Hydraulic pressure powered by occupant's energy via foot pedal and a drive chain to the pump increased the pressure inside the hydraulic system. Hydraulic pressure from the pump transferred to a main cylinder lower port, extending the piston rod and pushing an articulating member to move. Angular movement of the articulating member caused an occupant-seated frame to follow in ascending or descending motion depending on piston rod movement. Each cycle of workout for occupant can be preset to required load level.Type: GrantFiled: April 22, 2004Date of Patent: July 15, 2008Inventor: Banyat Somwong
