Description

Elliptical track fitness machine

technical field

The invention relates to the field of body-building equipment, in particular to a body-building machine that allows legs to move forward and backward along staggered elliptical tracks.

Background technique

Press, track fitness device is a kind of foot strength training equipment that moves along the crank track of the drive wheel by both feet interlacedly. The early structure is as shown in Figure 1. The front end is provided with a column 11 extending upwards, and a handrail bar 12 is pivotally provided on both sides of the column 11, and a transmission wheel 13 with a damping effect is provided at the rear end of the machine base 10, and a counter-rotating wheel 13 is provided on the axis center of both sides of the transmission wheel 13. To the crank 14 that extends, and between two free ends of crank 14 and the end of corresponding armrest bar 12, a pedal rod 15 is provided, and the middle section of the pedal rods 15 on both sides is respectively provided with a pedal 16 for the user to step on, so that the user can You can stand on the two pedals 16 with both legs, step on the feet and swing the armrest bar 12, and drive the transmission wheel 13 through the crank 14, so that the legs on the two pedals 16 can move forward and backward, and Utilize the damping effect of transmission wheel 13 to adjust its training effect;

The motion span of this custom-style elliptical trajectory fitness equipment is completely determined by the size of the body, that is to say, if the diameter of the transmission wheel 13 is large, then the motion span also becomes larger, otherwise if the diameter of the transmission wheel 13 is small, then its The movement span will also become smaller, and under the consideration of improving the movement effect and the swinging space of the hands, the transmission wheel 13 with a larger diameter is usually selected and the overall length is elongated, but this will increase the volume of the body. It will not only increase the cost of manufacturing and assembly, but also affect the space and convenience of storage and transportation, and is not suitable for general household use. Furthermore, the pedal 16 is directly actuated by the crank 14 of the transmission wheel 13, so its step height is also high. , resulting in large changes in the pitch angle of the user's legs and ankles, which affects the user's center of gravity and balance. On the contrary if reduce the diameter of transmission wheel 13, though can reduce its volume slightly, but can reduce its movement effect because of span is little.

Later, in order to improve the sports effect, some operators changed the transmission wheel originally located at the rear end of the machine base to the front end, and extended the pedal rod backward, so that the other end of the pedal rod was slid on the bottom of the machine base to extend backward. On the guide rails, such as Taiwan Patent Announcement No. 429791 and Announcement No. M262216 and other patent antecedents, but it still cannot overcome the excessive problem of the size of the elliptical track fitness device.

In addition, as shown in Figure 2, it is another kind of customary elliptical track fitness machine, which is provided with a column 21 at the front end of a shorter machine base 20, and a handrail bar 22 is pivotally provided on both sides of the column 21, and the machine Seat 20 rear end is provided with a transmission wheel 23, and this transmission wheel 23 both sides same axis is respectively provided with a guide rod 24 at the two ends of adjacent edge, and two guide rods 24 are respectively slidably provided with a pedal 25, and guide rod 24 front ends and The bottom ends of the pedals 25 are respectively pivoted with a connecting rod 26, 27 and the middle section and the bottom end of the armrest bar 22, so that when the user operates the armrest bar 22 and stepping on the transmission wheel 23, the two pedals 25 can be moved forward on the corresponding guide bar 24. , post-staggered movement;

However, although the aforementioned elliptical trajectory fitness equipment can shorten its length, because the guide rod 24 is connected to the edge of the transmission wheel 23, when the transmission wheel 23 rotates to the highest point, the user also rotates to the highest point at the same time, so that the center of gravity is improved. Therefore, if the user does not have the handrail bar 22 for holding, it will be too dangerous to use, so the handrail bar 22 is still a necessary design, and its volume cannot be effectively reduced. There are the aforementioned problems of placement, use and storage inconvenience.

Furthermore, no matter how the aforementioned different types of elliptical track fitness machines have their motion effects, they all have some common problems, that is, their volume cannot be effectively reduced (because the transmission wheel is reduced, the span also becomes smaller, and its motion is lost. effect), and at the same time have the disadvantages of occupying space and being difficult to move. Moreover, due to the large number of materials used, under the premise that the current steel price continues to rise, its consumption cost is also constantly being raised, which in turn affects consumers. Consumer willingness reduces its economic benefits. Therefore, recently, small-sized steppers have won the favor of most consumers due to their advantages of small size and low price. However, steppers can only do up and down staggered pedaling actions. , its action is comparatively monotonous, can't satisfy its exercise effect, therefore, if can simplify and reduce the structure and the volume of conventional elliptical trajectory fitness equipment, then should be able to attract the attention of consumer.

Therefore, a kind of " mini treadmill " such as the No. M271597 of Chinese Taiwan Patent Announcement is developed on the market, and its structure is as shown in Figure 3, and this treadmill comprises a base 30, and this base 30 tail end positions are fixedly provided with a fixed seat 31. An axial transmission wheel 32 is arranged on the fixed seat 31, and the transmission wheel 32 is set with a belt to drive a magnetic control wheel with a damping effect. In addition, the shaft centers on both sides of the transmission wheel 32 are respectively arranged to extend in opposite directions. The crank 33 of the base 30 is fixedly connected to an axially horizontal support 34 of a suitable height at the front end. The two ends of the support 34 are respectively pivotally provided with an inverted T-shaped cantilever 35, and the lower ends of the two cantilever 35 are pivotally provided with a pedal 37 respectively. Pedal rod 36, the proper position of the lower end of the pedal rod 36 is fixed with a transmission rod 38 pivotally connected with the free end of the crank 33;

The mini-treadmill of the aforementioned patents seems to have reduced the size of the Xi-style elliptical track fitness equipment, and also has the action of interlacing strides, but it is mainly obtained by reducing the diameter of the transmission wheel 32, but its stride distance is sure. Because the diameter of the transmission wheel 32 becomes smaller, and then becomes smaller, it can only do the staggered movement of small steps, and because the diameter of the transmission wheel 32 is small, the cycle time of each step is very short, forming a small running action , it is impossible for the user to adjust according to the amount of exercise, and at the same time, the movement of jogging for a long time is also prone to unstable center of gravity, resulting in accidental injuries, which still cannot meet the fitness needs of ordinary consumers.

In other words, due to the large volume of the Xi-style elliptical trajectory fitness equipment, there are complex structures and high manufacturing costs. During transportation, there will always be a problem of occupying space, which will invisibly reduce consumers' willingness to buy.

In view of this, the inventor of the present invention has made in-depth discussions on the problems of the aforementioned fitness equipment being too large in size or ineffective in exercise, and has actively sought a solution through years of experience in research and development and manufacturing of related industries.
