Description

[Detailed Description of the Invention] This invention relates to an improvement of a cycle trainer.

The inventor of the present application has already devised a cycle trainer in which the saddle swings left and right around the rear pole of the frame as a result of the rotation of the pedals.

In other words, a saddle integrated with a swinging support plate having a long hole is provided to support the front part of the swinging support plate and swing freely at the upper end of the rear pole of the frame, and a saddle is integrated with the frame on which the pedal shaft is mounted. A drive shaft connected to the pedal shaft through an appropriate transmission mechanism is extended upward from the housing, and the trochanter at the tip of the arm rod attached to the upper end of the drive shaft can be transferred into the long hole of the swing support plate. intervened in
The saddle swings left and right as the pedals rotate.

However, in the above-mentioned conventional cycle trainer, when the pedals are depressed in the same direction of rotation, the saddle swings from side to side quickly and slowly.

-In other words, when the pedals are rotated in the normal rotation direction (forward rotation), the saddle swings to the right faster and swings to the left slower, and the pedals are rotated in the opposite direction (reverse rotation). Sometimes the saddle will have the opposite effect, making the right swing slower and the left swing faster.

Therefore, if you can speed up or slow down the left and right swings of the saddle as needed, you can have various variations and be able to perform effective, appropriate, and interesting training, but in general, if you rotate the pedals normally, you can It is easy to pedal in one direction as you get used to the bicycle, but it is very difficult and difficult to pedal in the opposite direction.

Therefore, as a result of further research, the inventor of the present application succeeded in devising a cycle trainer as described below, which solves the above problems and provides excellent functions and effects.

To explain the cycle trainer according to the drawings, 1 is a frame, a handle 2 is mounted at the upper end of the front hole 1a, and a pedal shaft 21 having pedals 22 at both ends is rotatably mounted at the lower center of the frame. Each container housing 7 is provided integrally with the other.

Reference numeral 4 denotes a swing support plate having a long hole 5 in the front-rear direction, and the rear part of the saddle 3 is connected to the bent rear part 4b of the swing support plate with two coil springs 6 interposed therebetween, and the front part of the saddle 3 is connected to the tip of the bent front part 4a. The parts are each integrally attached in the front-rear direction.

The saddle 3, which is integral with the swing support plate 4', supports the front part of the swing support plate 4 and is swingably provided at the upper end of the rear pole 1b of the frame 1.

Reference numeral 8 denotes a cover pipe extending upward from the housing 7 in an angular direction perpendicular to the pedal shaft 21, into which the drive shaft 9 is rotatably inserted.

A trochanter 12 is attached to the tip end rod 11 of the arm rod 10 attached to the upper end of the drive shaft 9, and the trochanter 12 is rotatably engaged in the elongated hole 5 of the swing support plate 4. has been entered,
The rotation of the drive shaft 9 allows the saddle 3 to swing left and right around the rear pole 1b.

Reference numeral 13 denotes a worm wheel fixed to the drive shaft 9 in the housing 7, and is meshed with a worm 15 fixed to a worm shaft 14 installed and supported in the housing 7 in parallel with the pedal shaft 21. .

On the right side of the worm shaft 14, there is a switching gear 16, such as a feather key, which can be shifted to three positions as described later by left and right movement of a shift lever 17 whose operation knob protrudes upward through a through hole 7a on the top surface of the housing 7. It is mounted so that it can be moved in the axial direction by interposing it.

Also, on the right side of the pedal shaft 21 is a two-stage large gear 2.
4. A small gear 25 is fixed, and an intermediate gear 26 meshed with the small gear 25 is fixed to a rotatable intermediate portion 27 installed below the pedal shaft 21.

Therefore, by operating the external knob of the shifter 17, the switching gear 16 is brought into a position where it meshes with the intermediate gear 26 (forward rotation);
It is designed so that it can be shifted to three positions: a position where it meshes with the large gear 24 (reverse rotation) and a neutral release position.

In other words, between the pedal shaft 21 and the drive shaft 9 inside the housing 7, the drive shaft 9 can be rotated in the normal direction with respect to the pedal shaft 21 by external operation.
A switching gear transmission mechanism A that can shift to three stages of reverse rotation and neutral release is installed.

Further, in this invention, a convex plate portion 23 having a semicircular shape (half-moon cross section) or a trapezoidal cross section as shown by the chain line in FIG. 1 is integrally provided on one side of the tread plate 22a of the pedal 22.

Furthermore, as shown in Figures 2 and 3 of the drawings, a brake drum 18 is fixed to the left side of the pedal shaft 21, and a brake shoe 19 whose one end is fixed to the upper surface of the housing 7 is wrapped around the brake drum 18. A thumbscrew 20 screwed into the tip bent portion 19a is screwed from the top surface of the housing 7, and by screwing the thumbscrew 20 back into place, the brake shoe 19 is tightened or loosened to reduce the rotational torque. This allows for control.

The cycle trainer of this invention is as described above, and when you sit on the saddle 3 and pedal 22, you operate the shift lever 17 and shift it to the forward rotation position where the switching gear 16 meshes with the intermediate gear 26. When the pedal 22 is rotated in the normal direction, the drive shaft 9 rotates in the normal direction, and if the switching gear 16 is shifted to the reverse rotation position where it meshes with the large gear 24, the drive shaft 9 rotates in the reverse direction, and the switching gear 16 rotates in the reverse direction. If the drive shaft 16 is shifted to a neutral release position where it does not mesh with any of the drive shafts 9, the drive shaft 9 will not rotate.

The cycle trainer of this invention, like Narukami, has a housing of 7
A switching gear transmission mechanism A is interposed between the pedal shaft 21 and the drive shaft 9 inside, which can shift the drive shaft 9 relative to the pedal shaft 21 in three stages: forward rotation, reverse rotation, and neutral release by external operation. By a simple switching operation using a switching gear, the drive shaft 9 can be freely rotated forward or backward by rotating the pedals 22 in the same direction in the normal direction. The right swing can be selectively made faster or slower, allowing for training with various variations by combining the appropriate combinations as needed, allowing for effective and appropriate rowing according to the needs of the user. It has an outstanding effect that allows you to enjoy and lighten your training.

Furthermore, if the drive shaft 9 is shifted to a neutral position with respect to the pedal shaft 21, there is no swinging of the saddle 3, and training only by pedaling can be performed as in a conventional cycle trainer.

Furthermore, in this invention, a convex plate part 23 such as a semi-cylindrical plate is provided on one side of the tread plate 22a of the pedal 22, so that when the convex plate part 23 is stepped on and the pedal is pedaled, the sole of the foot is It has excellent effects that can improve blood circulation and stimulation, contributing to health promotion.

Furthermore, the tread plate 22a is not provided with the convex plate portion 23.
If the other tread is used, it can be used in the same manner as before.
