Description

[Detailed description of the invention] This invention relates to an improvement of a cycle trainer that trains legs by using a bicycle.

In recent years, cycle trainers, which can be easily used by anyone of any age or gender, including housewives, have become popular not only from a beauty standpoint, but also because the need to maintain and improve physical strength has become widely recognized. The number of people who received it increased, and it came to be widely prized by the general public.

However, conventional cycle trainers are designed to focus solely on training the legs by pedaling, so they can be used to, for example, strengthen the flexibility of the lower back, remove fat from the abdomen (waist), and strengthen the muscles. In addition to being unsuitable for this purpose, it also had shortcomings such as the lack of variety in its movements, making it easy to get stuck in a rut and become bored.

The purpose of this invention was to provide a cycle trainer as described below to eliminate the various drawbacks of the prior art.

To explain the cycle trainer of this invention with reference to the drawings, reference numeral 1 denotes a frame, a bundle 2 is attached to the upper end of the front pole 1a, and a pedal shaft 9 having pedals 10 at both ends is rotated by a bearing 15 at the lower center of the frame. A freely supported container casing 8 is provided integrally with each other.

Reference numeral 4 designates a swinging support rod having an elongated hole 5 in the front-rear direction, and has two buffering coil springs 7 interposed at its bent rear end 4b so that the rear of the saddle 3 is connected to the rear end of the saddle 3, and the swing support rod 4 is connected to the tip of its bent front end 4a. saddle 3
The front parts of each are integrally attached in the front-rear direction.

The saddle 3, which is integrated with the oscillating support 4, is provided so that the bent rear end 4a of the oscillating support 4 is rotatably supported on the upper end 1c of the rear pole 1b of the frame 1, so that the saddle 3 can swing freely. It is being

Note that 6 is a bearing.

Now, the above-mentioned device housing 8 has a plurality of divided structures, and a worm 11 is wedged to the pedal shaft 9 inside the housing.

Further, a drive shaft 12 extending in a direction perpendicular to the pedal shaft 9 is rotatably supported at its lower end into the housing 8 from the upper surface, and extends upward in an inclined manner.

A worm wheel 14 that meshes with the worm 11 within the housing 8 is wedged to the lower end of the drive shaft 12.
The worm 11 and the worm wheel 14 constitute a gear reduction transmission mechanism A.

Note that other gear transmission mechanisms, friction wheel transmission mechanisms, or the like may be used as the transmission mechanism A.

Note that 13 is a cover pipe that hides the drive shaft 12;
6 is a bearing.

Reference numeral 17 denotes an arm rod whose base end is fixed to the upper end 12a of the drive shaft 12, and a tip protrusion 18 having a trochanter 19 such as a bearing attached to the upper end projects upwardly. The trochanter 19 of the projecting rod 18 is rotatably engaged in the elongated hole 5 of the swing support plate 4.

When the pedal 10 is depressed, the pedal shaft 9 is rotated, so that the saddle 3 swings left and right about the rear pole 1b.

This devised cycle trainer has the structure described above, and when you sit on the saddle 3 and pedal 10, the drive shaft 12 rotates from the pedal shaft 9 via the transmission mechanism A, and at the same time, the arm rod 17 integrated with it rotates. The oscillating support plate 4 with which the saddle 3 is integrated is oscillated left and right around the rear pole 1b, and a user who grips the bundle 2 and sits on the saddle 3 automatically moves his/her hips to the left and right along with the saddle 3. This is a motion that involves repeated rotation.

Note that if the reduction ratio of the transmission mechanism A is, for example, 1110, then the saddle 3 will perform one stroke of left and right swinging motion for 10 rotations of the pedal 10.

The cycle trainer of this invention has a drive shaft 1 connected to a pedal shaft 9 via a suitable transmission mechanism A, as shown in Narukami.
The tip end rod 18 at the tip of the arm rod 17 fixed to the upper end of the saddle 3 is inserted into the elongated hole 5 of the swing support plate 4 integrated with the saddle 3 via the trochanter 19, and the rotation of the pedal 10 causes the saddle 3 is made to swing left and right around the rear pole 1b,
When the user sits on the saddle 3 and pedals 10, the saddle 3 automatically swings its head from side to side, causing the user to repeatedly shake the lower back part of the seated body from side to side, and the user pedals 10. At the same time as training the legs, it also helps to flexibly train the lower back, remove fat from the abdomen (waist), and strengthen the muscles. It is also excellent because it can contribute to the functional recovery of people who have injured their internal organs or lower back, in other words, rehabilitation. It has the effect of

In addition, since the weight of the user is placed on the saddle 3, a stronger force is required to pedal the pedals 10, so the training of the legs and hips by pedaling the pedals 10 is often strengthened by bird roading, and conventionally. By mixing the simple action of pedaling the pedals 10 with the action of shaking the hips, and by appropriately changing the transmission mechanism A, an interesting training can be performed, which has the excellent effect of allowing the user to exercise his body while having fun.
