Definitions

  • the present invention relates generally to exercise equipment and, more particularly, to exercise equipment having selectable resistance, components for effecting the selection of a desired amount of resistance and related methods.
  • apparatuses and devices configured to help individuals exercise and maintain a desired level of health and fitness
  • Many strength training apparatuses are configured to provide selective resistance so that a user of the apparatus may appropriately tailor their exercise regimen. For example, when the apparatus is used by multiple users, each individual using the apparatus may be at a different strength level and need to adjust the resistance according to their specific capabilities. Additionally, as an individual gets stronger, they often desire to increase the resistance provided by the apparatus so as to maintain or increase the intensity of their workout, Additionally, many strength training apparatuses are configured to accommodate different types of exercises so that a user can target different muscle groups based on the selection of exercises they participate in.
  • a strength training apparatus may- enable an individual to alternate between chest presses, curls, pull-downs, or a variety of other exercises while using the same basic resistance mechanism.
  • the resistance mechanism is typically configured to provide selective resistance because most users do not perform, for example, chest presses, curls and pull downs using the same amount of resistance for each exercise.
  • a relatively popular type of apparatus used for strength training includes one which employs a plurality of stacked weight plates. Each weight plate conventionally weighs a specified denomination (e.g., 5 pounds or 10 pounds (approximately 2,27 kilograms or 4.54 kilograms)).
  • each weight plate is 10 pounds (approximately 4.54 kilograms)
  • selection of a single weight plate results in a resistance of 10 pounds (approximately 4,54 kilograms)
  • selection of 4 weight plates results in a resistance of 40 pounds (approximately 18.14 kilograms).
  • a cable is led through a pulley or series of pulleys and is attached to one or more of the weight plates.
  • the free end of the cable is coupled to a handle for engagement by a user during exercise.
  • the pulley and cable assembly is also coupled with a structure such as a selector rod associated with the weight stack that enables the user to define the level of desired resistance.
  • the selector rod conventionally passes through a channel that is collectively defined by aligned apertures formed in each of the plurality of stacked weight plates.
  • the selector rod also conventionally has a plurality of longitudinally spaced apertures extending transversely through the rod that are configured to align with corresponding channels or openings formed in each weight plate.
  • a selector pin is placed through a selected weight plate and engages the corresponding aperture of the selector rod such that, when the selector rod is displaced by the attached cable and pulley system, the selector pin causes the engaged weight plate, as well as any weight plates disposed thereabove, to be displaced along with the selector rod.
  • selector pins with weight stacks of an exercise apparatus has been relatively efficient and effective in terms of enabling multiple users to use the same machine as well as enabling individual users to use a single machine for a variety of different exercises.
  • the use of a selector pin or similar structure, such as described above may pose a hazard to the user of the exercise apparatus.
  • a user of the apparatus may only partially engage the selector pin with the selector rod.
  • the selector pin may become disengaged during an exercise routine causing the weight plates to fall and essentially eliminating all resistance instantaneously. Such a situation may potentially result in injury to the user of the equipment, damage to the equipment itself, or both.
  • selector pins may vary in size, shape and strength from one apparatus to another.
  • an exercise apparatus having a resistance selector mechanism that reduces or eliniiiiaf.es the ability of users to interchange components of one machine with another.
