  • 2. Description of Related Art
  • At present, fitness equipment is in wide use, whereas a weight trainer is the commonest required fitness equipment of sports and fitness exercise.
  • A typical weight trainer has a weight allocating device and at least a transmission device connected to the weight allocating device. The weight allocating device has a plurality of selection tabs adjustable by a user according to the weight required for muscle training and therefore capable of providing an appropriate weight load. However, the weight trainer has a fixed training goal and effect, but is not capable of counting or calculating calorie consumption during fitness exercise. To evaluate the sports and fitness exercise taken by them, users have to record or read related fitness exercise data to the detriment of efficient promotion of fitness exercise.
  • Hence, as shown in FIG. 10, Taiwan Published Patent Application 201034715 discloses a fitness equipment that comprises a reed switch 94 disposed on a frame 92 of a weight trainer 90 and adapted to quantify fitness exercise-related data, wherein a magnetic material is coated on selection tabs 96. Once a user pulls the selection tabs 96, the reed switch 94 will identify the user's fitness exercise condition according to a detected magnetic change. However, the aforesaid magnetic sensing method fails to ensure the maintenance of consistency in the distance between the reed switch 94 and the selection tabs 96 due to a production tolerance of the selection tabs 96. Furthermore, a load device 98 of the weight trainer 90 is erected on the floor and thus is unlikely to maintain an angle required for parallel arrangement of the load device 98 and the reed switch 94. In addition, an error of the position of a fall of the selection tabs 96 is likely to cause the reed switch 94 to make a wrong judgment. Accordingly, the detection status of the structure is relatively unstable.
  • In conclusion, the conventional fitness equipment has the aforesaid drawbacks and thus has room for improvement.
    • SUMMARY OF THE INVENTION

  • The present invention achieves the above and other objectives and advantages specifically with the following technical solution. A weight trainer with a load detection system comprises a frame, a load detecting device, and a display device. The frame has a transmission device, a weight allocating device, and a stand. The transmission device is disposed on one side of the frame. The weight allocating device is connected to the transmission device and capable of moving in a vertical direction of the stand. The load detecting device is disposed beneath the weight allocating device. The load detecting device comprises a sensor, a base and a platform. The sensor is abuttingly disposed between the base and the platform. The display device is electrically connected to the load detecting device.
  • Accordingly, the present invention is effective in detecting a weight change precisely, enabling a user taking fitness exercise to gain access to information thereof in real time, quantifying the information, and thereby promoting fitness exercise efficiently.
