Definitions

  • the present disclosure relates to the technical field of fitness equipment, and more particularly, to a smart wall pulley for fitness.
  • a smart wall pulley for fitness can help people in exercising muscles, body-shaping, and effectively improving physical quality, therefore it is highly popular with the majority of fitness enthusiasts.
  • a common smart wall pulley is composed of two handles and an elastic rope. Since the smart wall pulley for fitness has the characteristics of small floor space and portability, it can help an exerciser to do all-around exercises any time any where, including for example a strength exercise, a flexibility exercise, a pulling exercise, a stretching exercise and the like, and therefore it is an indoor fitness equipment having a very high degree of freedom.
  • an existing smart wall pulley for fitness cannot perform data statistics for the exercise process of the exerciser while the exerciser is doing exercises, thus it has a low degree of intelligence.
  • an adjusting buckle applies a shear force on the elastic rope, which would easily cause the elastic rope to be broken after a long-term use.
  • US2016325132A1 discloses an exercise device having a band/cord which extends and retracts from a housing.
  • the apparatus allows users to conduct various physical workout exercises and also to generate electricity.
  • the user is provided a variety of controllable functions related to exercising such as tracking and/or displaying information during the physical workout as well as tracking and displaying information related to the energy generated by the apparatus.
  • a smart wall pulley for fitness includes an elastic rope, a motion sensing detection device, a fixed pulley assembly, and an adjuster.
  • the elastic rope is elastic.
  • the motion sensing detection device is provided at one end of the elastic rope.
  • a battery, a circuit board and a tension sensor are provided within the motion sensing detection device. The battery and the tension sensor are electrically connected to the circuit board.
  • the tension sensor is configured to detect a pulling force bore by the elastic rope.
  • the adjuster includes a shell and a winding post located within the shell. The other end of the elastic rope passes into the shell, then is wound around the winding post, then passes out from the shell. The other end of the elastic rope is fixedly connected to the shell after being wound around the fixed pulley assembly.
  • the winding post is provided within the shell and the elastic rope is wound around the winding post. Therefore, when a user delivers a part of the elastic rope into the shell of the adjuster, the elastic rope may be moved relative to the winding post. Further, Due to the limited space in the shell, another part of the elastic rope will be extruded out of the shell under the drive of the elastic rope, therefore the distance between the adjuster and an end of the elastic rope can be adjusted and thus the length of the smart wall pulley can be adjusted.
  • both the two parts of the elastic rope may each are subjected to a pulling force, and as the pulling force increases, the elastic rope applies a larger winding force to the winding post, such that the winding post can fix the elastic rope.
  • a pulling force bore by the elastic rope can be detected, therefore a user's training condition can be monitored and recorded, thereby facilitating the user to perform a detailed planning on the training.

  • a smart wall pulley 100 for fitness is described below with reference to FIGS. 1-9 .
  • a smart wall pulley 100 for fitness includes an elastic rope 110, a motion sensing detection device 10, a fixed pulley assembly 130, and an adjuster 140.
  • the elastic rope 110 is elastic, and the motion sensing detection device 10 is provided at one end of the elastic rope 110.
  • a battery 121, a circuit board 16 and a tension sensor 124 are provided within the motion sensing detection device 10, and the battery 121 and the tension sensor 124 are electrically connected to the circuit board 16.
  • the tension sensor 124 may be configured to detect a pulling force the elastic rope 110 is bearing, and transmits detected data to an electric component on the circuit board 16. And then, the corresponding electric component converts, through data conversion, information detected by the tension sensor 124 into a form of information that can be read by a user, such that the user can know the pulling force being applied to the smart wall pulley 100.
  • the tension sensor 124 may be further configured to adjust an overall length of the smart wall pulley 100 in consideration of elastic resistance of the elastic rope 110, such that the smart wall pulley 100 can satisfy needs of different users for different lengths.
  • the battery 121 may supply power to the tension sensor 124 and electric components on the circuit board 16.
  • the adjuster 140 includes a shell 141 and a winding post 142 located within the shell 141. As shown in FIG. 2 in which a routing path of the elastic rope 110 is indicated by arrows, the other end of the elastic rope 110 passes into the shell 141, then is wound around the winding post 142, then passes out from the shell 141. Finally, the other end of the elastic rope 110 is fixedly connected to the shell 141 after being wound around the fixed pulley assembly 130.
  • the adjuster 140 can divide the elastic rope 110 into two parts.
  • one part of the elastic rope is from the one end of the elastic rope 110 to the adjuster 140, and is provided with the motion sensing detection device 10 thereon.

  • both two parts of the elastic rope 110 may each are subjected to a pulling force.
  • the elastic rope 110 Under the action of the pulling force, the elastic rope 110 is wound around the winding post 142, and as the pulling force increases, the elastic rope 110 applies a larger winding force to the winding post 142, such that a relative position between the elastic rope 110 and the winding post 142 can not be easily changed and the winding post 142 can play a role of fixing the elastic rope 110.
  • the smart wall pulley 100 is in a natural state, the elastic rope 110 is not subjected to an external force and can be wound around the winding post 142 in a natural state, and there is no acting force between the elastic rope 110 and the winding post 142.
  • the elastic rope 110 When a user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 can be moved relative to the winding post 142. Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110. Thus, a distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted, thereby the length of the smart wall pulley 100 can be adjusted.
  • the user can drive the adjuster 140 to move along the elastic rope 110 by applying a force to the elastic rope 110 on one side of the adjuster 140.
  • the elastic rope 110 can be moved around the winding post 142, and both a length of the elastic rope 110 located on one side of the adjuster 140 and a length of the elastic rope 110 located on the other side of the adjuster 140 can be changed, that is, the overall length of the smart wall pulley 100 may be adjusted at this time.
  • the winding post 142 is provided within the shell 141 and the elastic rope 110 is wound around the winding post 142. Therefore, when the user delivers a part of the elastic rope 110 into the shell 141 of the adjuster 140, the elastic rope 110 may be moved relative to the winding post 142. Further, Due to the limited space in the shell 141, another part of the elastic rope 110 will be extruded out of the shell 141 under the driving of the elastic rope 110, therefore the distance between the adjuster 140 and an end of the elastic rope 110 can be adjusted and thus the length of the smart wall pulley 100 can be adjusted.
