Description

[Detailed description of the invention] This invention applies a load to the flywheel in a bicycle pedal pedal that rotates the flywheel, and the added load can be displayed on the scale of the meter. Regarding health equipment. Previously known load devices for health equipment used caliper brakes, but depending on whether the clamping force was strengthened or weakened, the pedal force would simply become lighter or heavier. However, it is inconvenient that it is not possible to apply the same numerical load each time. The object of the present invention is to provide a device that has a simple mechanism and can display load force relatively accurately.

The present invention will be explained with reference to an embodiment shown in the drawings. 1 is a frame of a health machine, and a drive wheel 2 on a petal shaft and a flywheel 3 associated with a chain are provided on the frame. The base end of a rotating rod 4 is pivotally supported on the hub shaft of the wheel, and a caliper brake 5 for braking the flywheel is provided on the rotating rod.The caliper brake and a control lever 7 provided on the handle 6 The front end of a sliding rod 10 has a meter box 9 installed in the front part of the frame, and a scale (not shown) pointer displayed on the meter box is provided along the frame 1. The cable 11 connected to the rear end of the sliding rod is connected to the guide pulleys 12 and 13.
The cable is hung on a pulley 14 provided on one side of the rear end of the rotating rod 4 through the cable, and the base end of this cable is fixed to the chain stay 15. The sliding rod is made to slide by mutual action with the rotational movement of the meter, and the meter pointer provided at the front end is moved along the dial.

Since the present invention is constructed as described above, an exerciser who straddles the saddle 17 and steps on the pedals to rotate the flywheel 3 which is transmitted by a chain can do the following:
A load is applied to the flywheel 3 via the caliper brake 5 by operating the control lever 7 according to the physical strength. By the way, this caliper brake 5
is mounted on the rotating rod 4, so the flywheel 3 rotates due to the pedal force, and the rotational force causes the rotating rod 4 to which the caliper brake 5 is attached to rotate in the direction of rotation of the flywheel. move along. As a result, the pulley 1 provided on the rotating rod 4
Since the base end of the cable 11 hung on the cable 4 is fixed to the chain stay, it pulls the sliding rod 10 to which the other end is attached via the guide pulleys 12 and 13 against the action of the brake spring 16. A pointer that moves along the scale of the meter box is attached to this sliding rod, so that the pointer indicates the scale as the sliding rod slides. That is, since this pointer indicates the intensity of the load applied to the flywheel, the pointer changes depending on the strength of the load, and the indication of the pointer is relatively accurate. According to the present invention, an exerciser can always exercise rationally by memorizing or recording the scale of the meter that indicates the load that matches his or her physical strength, and stepping on the pedals with a load that matches that scale. There are effects that can be done.
