A manual treadmill that applies consistent pressure to the user's abdomen.

Abstract

This invention introduces a human-powered treadmill designed to provide a consistent pressing force to the user's abdomen, facilitating the movement of the treadmill belt through the user's feet. The treadmill features abdominal drive objects, such as flexible objects (abdominal bands or abdominal belts) and rigid objects (abdominal pads or abdominal rollers), positioned at the front of the treadmill frame. As the user leans forward during exercise, the abdomen pushes against these objects, generating a backward propulsion force in the feet, which propels the treadmill belt. This design addresses safety and usability issues associated with conventional electric and non-electric treadmills, enabling high-intensity workouts with or without the need for high speed or incline. The abdominal drive objects are adjustable to accommodate different user sizes and include options for resistance / braking systems to vary workout intensity.

[0001] (Reference to Related Applications) This application claims the benefit of priority of U.S. Provisional Patent Application No. 63 / 525,167, entitled "MANUAL TREADMILL WITH CONSISTENT PUSH FORCE ON USER’S ABDOMEN", filed on July 6, 2023, which is hereby incorporated by reference in its entirety.

[0002] (Technical Field) The present invention relates to treadmills used for walking and running exercises. Specifically, the present invention introduces a human-powered treadmill designed to apply a consistent push force to the user's abdomen (ab), which is then transferred to the treadmill belt via the user's feet.

[0007] The treadmill can be either a conventional belt treadmill or a slat belt treadmill. The ab-push object may be solid (pad or roller) or flexible (band or belt). The following description is illustrative and should not limit the invention to the specific embodiments shown.

[0008] Figures 1 and 2 show a treadmill having an abdominal roller 68 connected to a telescopic pole (tensioning pole) 67, the telescopic pole 67 being attached to the treadmill frame via a cantilever 65 and adapter 61. The height of the roller can be adjusted, and the roller can rotate around the shaft for smooth operation. The user's abdomen pushes against the roller, generating a driving force in the user's feet that pushes the treadmill belt backward. In this case, the abdominal roller 68 can be replaced with an abdominal pad.

[0009] Figures 3 and 4 show a treadmill having an abdominal pad 45 connected to a frame handlebar 11 via a cantilever 44. The height of the abdominal pad can be adjusted to suit the user. The abdominal pad can be soft or elastic, and the cantilever may include a spring for additional damping. The user's abdomen presses against the abdominal pad, moving the treadmill belt.

[0010] Figures 5 and 6 show a treadmill having a basic structure including a base 1, a footboard frame 2, and a treadmill belt 9. The abdominal band 24 is connected to the end of the handlebar 11 and can be vertically adjusted to fit different users. The number of abdominal bands can vary, and the abdominal bands may be elastic or non-elastic. The user generates driving force by pressing on the abdominal band while walking or running.

[0011] Figures 7 and 8 show a treadmill having an abdominal roller 86 connected to a handlebar 11 via a shaft 85. The height of the abdominal roller can be adjusted, and the abdominal roller 85 can rotate around the shaft 85 for smooth running. The user can push the treadmill belt backward by generating force by pushing the abdominal roller for their feet. In this case, the abdominal roller 85 can be replaced with an abdominal pad.

[0012] Figures 9 and 10 show a treadmill having an adjustable-height abdominal roller 103 connected to a handlebar 11 via a shaft 102. The user pushes the abdominal roller to generate force and move the treadmill belt. In this case, the abdominal roller 103 can be replaced with an abdominal pad.

Claims

1. It is a human-powered treadmill, Frame structure including base, The front roller and rear roller are supported by the aforementioned frame structure, A tread belt attached to the front roller and the rear roller, A drive device coupled to the frame, which is an abdominal drive object directly connected to the front portion of the frame of the human-powered treadmill, and which is positioned at a height or position suitable for user engagement on the front or middle portion of the user's body, wherein when the user leans forward on the tread belt of the human-powered treadmill while walking or running, the user's abdomen presses against the abdominal drive object, generating a backward propulsive force in the user's feet, thereby causing the user's feet to push the tread belt back. Includes means for adjusting the position or height of the abdominal pressing object to accommodate users of different sizes, A human-powered treadmill.

2. The human-powered treadmill according to claim 1, wherein the abdominal drive object is a band / belt, a pad having a smooth and soft surface, or a rotatable cylinder (roller) having a smooth and soft surface.

3. The position of the abdominal drive body can be adjusted vertically via a cantilever to accommodate the height and body type of different users, as described in claim 1.

4. The manual treadmill according to claim 1, comprising a resistance / braking system that increases the resistance to moving the treadmill belt when the user stops engaging the abdominal pressing object, thereby safely stopping the tread belt or slat belt.

5. The manual treadmill according to claim 1, which is designed for hands-free operation, and the user propels the belt through abdominal pressure without requiring a pushing motion.

6. A manual treadmill according to claim 1, further comprising means for generating and adjusting resistance to the movement of the tread belt or slat belt to simulate different workout intensities.
