Cushion adjustable and display devices for treadmills

Cushion adjustable and display devices for treadmills description/claims

The present invention relates to cushion adjustable and display devices for treadmills, wherein a resilient roller can be moved to a desired position under the deck so as to evenly support the load and the deformation of the deck can be displayed.

A conventional treadmill 40 is shown in FIG. 9 and generally includes a frame with two side support boards 411 and two rollers 43 are connected between the two side support boards 411. A motor 41 is connected to a front end of the frame and two posts 42 extend from two sides of the frame so as to be connected with a handle which is not shown. A plurality of resilient members 412 are located on a top of each of the side support boards 411 and a deck 44 is supported on the resilient members 412 and fixed to the frame. An endless belt 45 is driven by the rollers 43 which are driven by the motor 41 and the deck 44 is located between the top portion and the bottom portion of the loop-like endless belt 45. As shown in FIG. 10, when a user walking or running on the endless belt 45, the load is supported by the resilient members 412 which are deformed by the load and absorb the shocks so that the user feel comfortable when using the treadmill. However, the resilient members 412 cannot effectively provide a satisfied result to the users and cannot be adjustable according needs of different users.

The present invention intends to provide cushion adjustable and display devices which respectively adjust the position of the resilient roller under the deck and displays levels of the deformation of the deck.

The present invention relates to a treadmill which comprises a frame having two sides and a motor and two rollers are connected between the two sides. Each of the two sides of the frame has a vertical portion and a horizontal portion, a plurality of resilient members are fixed on each of the two horizontal portions. A deck is supported on the resilient members and fixed to the horizontal portions. The deck is located between a top portion and a bottom portion of a loop-like endless belt driven by the two rollers. A cushion display device has an indication member which is fixed to an underside of the deck and movably points marks seen on an outside of one of the vertical portions when the deck is deformed in vertical direction. A cushion adjustable device is located on one of the horizontal portions and beneath the deck. The cushion adjustable device has a base plate fixed on the horizontal portion and a movable member is movably engaged with a groove defined in the base plate. A resilient roller is connected to the movable member which can be operated from an outside of the frame.

The primary object of the present invention is to provide a cushion adjustable cushion device for a treadmill wherein the movable cushion device has a resilient roller which can be moved relative to the underside of the deck when needed.

Another object of the present invention is to provide a cushion display device for a treadmill wherein the deformation of the deck in vertical direction can be seen from outside of the frame by the cushion display device.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
