Bicycle trainer with counterweight

The present invention relates to a bicycle training device with a counterweight function, in particular, a weight can be added to increase the weight of the inertia wheel, so that the exercise of the bicycle trainer can reduce the rotation speed and thus reduce the tire wear, and the temperature of the damping member is not easy due to the reduced rotation speed. Raised bicycle trainer.

Although bicycle riding is a sports and leisure activity that many people like to engage in, it is not suitable for bicycles to ride on the road due to the busy traffic and safety problems of today's cities. In recent years, a bicycle trainer that can be placed at a fixed point has been developed. The rear wheel of the bicycle can be erected on the bicycle training device, so that the rear wheel of the bicycle can be in contact with the damper wheel of the bicycle trainer. Therefore, when the user steps on the bicycle to drive the rear wheel, the resistance of the damper wheel is utilized, and the rear wheel can be used. The damper wheel is driven to rotate by friction. Since the damper wheel train is connected with the oil resistance type, mechanical or reluctance type damping member by a shaft, the speed of the damper wheel is increased, and the rapid rotational friction between the damper wheel and the bicycle rear wheel is likely to cause the rear wheel to wear and is damped. After the wheel rotates, the shaft is transmitted by the rotary power input damping member for damping operation. Therefore, the increase of the speed of the damping wheel easily causes the temperature of the damping member to rise, thereby affecting the service life of the damping member. Moreover, the current bicycle training device has no weight structure, so that the user can only practice with the resistance of the single weight damping wheel, which will not be conducive to the user to improve the riding speed.

The present invention provides a bicycle training device with a weight function, comprising a stand set, the stand set includes a base and a seat spaced apart from the base, and includes a pivoting member mounted on the base and including a damping In combination with the pivoting member, the damper member includes a shaft pivoted on the pivoting member, and includes a damper wheel fixed to the peripheral surface of the shaft, and includes a first inertia wheel, the first inertia wheel including a first end and a second end spaced apart from each other, a first through hole extending from the first end to the second end, the first inertia wheel being fixed to the end of the shaft, thereby including a first inertia at the end of the shaft The wheel weight is formed into a first counterweight state, and includes a second inertia wheel detachably coupled to the first inertia wheel, the second inertia wheel including a second end and a second end spaced apart in the lateral direction, and a second The end surface includes a joint portion, and a second through hole is penetrated from the joint portion to the second end. When the joint portion abuts the first inertia wheel, the first and second through holes are aligned, and the first and second portions are threaded by a lock. Perforated and locked at the end of the shaft, thus including the first inertia wheel at the end of the shaft The weight and the weight of the second inertia wheel are increased to form a second counterweight state.

The first feature is that when the bicycle trainer is in the second counterweight state, the weights of the first and second inertia wheels increase the weight of the rotation of the push shaft and the damper wheel, so that the user is the same as the first match. When the force of the heavy state is stepped on the second counterweight state, the damper wheel is not easily driven to rotate, so that when the pedal is stepped with the same force, the speed of the damper wheel and the shaft is lowered, and the damper wheel is reduced for the bicycle tire wear. Moreover, the speed of the damper wheel and the shaft is lowered, that is, the temperature at which the damper is operated is not easily increased, thereby achieving the effect of prolonging the service life. Moreover, when the bicycle trainer is switched to the second counterweight state, the inertia wheel weight is increased, and the user's gravity training mode can be provided, which is beneficial to improve the racing level.

Referring to Figures 1 to 5, the bicycle exerciser 10 of the present invention includes a standable group 12 that can be unfolded and collapsed. The stand set 12 includes a base 14 and is different from the base 14. A highly spaced apart base 15 includes a support frame 16. An adjustment rod 18 is pivotally disposed at the end of the support frame 16 of the base 14. When the stand set 12 is unfolded, the base 14 is placed on the ground, and the stand 15 is located above the base 14. Thereby, a bicycle rear wheel spindle (not shown) is mounted on the frame 15 for the user to The fixed step can drive the rear wheel of the bicycle to rotate.

The weight training bicycle trainer 10 further includes a pivoting member 22, and the pivoting member 22 includes two laterally spaced apart panels 24, and a bearing 25 is disposed in each of the two brackets 24. One end of the pivoting member 22 is pivoted on the support frame 16 , and the end of the adjusting rod 18 abuts against the pivoting member 22 . When the pivoting member 22 is to be adjusted in height, the pivoting member 22 is pushed in or out according to the adjusting rod 18, thereby adjusting the height of the pivoting member 22.

The weight training bicycle trainer 10 further includes a damper portion 20 including a damper member 26, which may be a magnetoresistive type, a gear type or a oil resistance type. The damper member 26 includes a shaft 28 that is rotatable, and a screw hole 29 is provided at the end of the shaft 28. The damper member 26 is fixed on a side of the frame 24, and the shaft 28 is disposed in the pivoting member 22 through the two bearings 25. A damper wheel 32 is affixed to the circumference of the shaft 28 to provide an erected rear wheel surface of the bicycle that abuts against the damper wheel 32.

The weight training bicycle trainer 10 further includes an inertia wheel set 50 coupled to the end of the shaft 28 of the damper member 26. The inertia wheel set 50 includes a first inertia wheel 52 and a second inertia wheel 62 detachably coupled to the first inertia wheel 52.

The first inertia wheel 52 includes a first end 54 and a second end 56 spaced apart from each other. A first circumferential surface 58 is formed between the circumferences of the first and second ends 54 and 56. One end 54 extends through the second end 56. The first perforation 60 of the first inertia wheel 52 is sleeved tightly at the end of the shaft 28.

The second inertia wheel 62 includes a first end 64 and a second end 66 spaced apart from each other. The first end 64 includes a joint portion 70, and the joint portion 70 includes a recessed portion from the first end 64 toward the second end 66. Extending into a wall surface 72, the end of the wall surface 72 forms a contact surface 74 spaced apart from the second end 66, and a second through hole 76 extends from the joint portion 70 to the second end 66. The outer diameter of the first circumferential surface 58 of the first inertia wheel 52 is smaller than the inner diameter of the wall surface 72 of the second inertia wheel 62. Therefore, the second inertia wheel 62 can be sleeved with the first inertia wheel 52 by the joint portion 70, so that the joint portion 70 is The wall surface 72 abuts against the first circumferential surface 58 of the first inertia wheel 52, and the abutment surface 74 of the joint portion 70 abuts against the second end 56 of the first inertia wheel 52, so that the first and second perforations 60, 76 are aligned And the first and second through holes 60, 76 are inserted into the screw holes 29 provided at the ends of the lock shafts 28, and the second inertia wheel 62 and the inertia wheel 52 are fixed to the shaft. End of the rod 28.

When the present invention is in operation, the first inertia wheel 52 is fixed to the end of the shaft 28 to form a first counterweight state (as shown in Fig. 3). In the first counterweight state, the end of the shaft 28 has the weight of the first inertia wheel 52, so that a bicycle rear wheel spindle (not shown) can be erected on the frame 15, and the rear tire surface of the bicycle abuts against the damping wheel. 32 surface, by which you can use the foot to pedal the bicycle to drive the rear wheel for fixed-point riding activities. And when the user wants to perform the counterweight operation, the second inertia wheel 62 can be coupled to the first inertia wheel 52, and thus the first and second inertia wheels 52, 62 are at the end of the shaft 28 to form a first Two counterweight states (as shown in Figures 4 and 5).

The present invention has the following features. First, when the weight training bicycle trainer 10 is in the second counterweight state, the total weight of the first and second inertia wheels 52, 62 is such that the user erects the same as the pedal bicycle. In the first counterweight state, when the bicycle rear wheel is stepped on the second counterweight state, that is, since the total weight of the first and second inertia wheels 52, 56 is greater than the weight of the first inertia wheel 52, It is not easy to drive the damper wheel 32 to rotate by the rear wheel of the bicycle. Therefore, when the same force is used to step on, the rotation speed of the damper wheel 32 and the shaft 28 in the second weight state is significantly reduced, thereby reducing contact with the damper wheel 32. The rear wheel of the bicycle is worn. Moreover, another advantage obtained by the reduction of the rotational speed of the damper wheel 32 is that the operation of the shaft 28 into the damper member 26 does not easily raise the temperature of the damper member 26, thereby achieving the effect of extending the service life of the bicycle trainer. Moreover, when the bicycle trainer 10 is switched to the second counterweight state, the bicycle trainer 10 increases the weight, and the user must step on the pedal more vigorously, thereby forming a gravity training function, and improving the competition of the bicycle riding training. Speed level.

The basic teachings of this creation have been described, and many extensions and variations will be apparent to those having ordinary skill in the art, for example, the joint 70 of the first inertia wheel 52 and the second inertia wheel 62 The abutting joint 70 can form a convex portion of the second inertia wheel 62 at the second end 64, and a second end 56 of the first inertia wheel 52 forms a recess corresponding to the joint portion 70, and then The locking member 78 is threaded and locked to the end of the shaft 28 to combine the first and second inertia wheels 52, 62 together, as is appreciated by those skilled in the art.
