1. Field of Invention
The present disclosure relates to an exercise apparatus. More particularly, the present disclosure relates to a high knees exercise apparatus.
2. Description of Related Art
Exercise apparatuses make raining day and limited ground no longer be problems of doing exercise. Therefore, exercise apparatuses are main priority for modern people who are always busy but want to keep in shape. It is well-known that walking and running are body exercise which not only can burn calories and firm muscles but also can enhance myocardial function and increase lung capacity. Accordingly, treadmills, steppers, and elliptical trainers are most common exercise apparatus compared to others on the present market. However, users barely lift their knees high when using those exercise apparatus and improvements of muscle strength and body shape are mostly concentrated on their calf only.
High knees exercise is usually taken as a component of warm-up exercise to get heart rate going and also can burn calories and firm muscles as walking and running. This exaggerated knee motion further provides an excellent workout for the knees, hips, lower body, lower abdomen, and lower back and can enhance body strength, speed, balance, and flexibility. But, no apparatus for executing high knees exercise has been developed nowadays.
According to one aspect of the present disclosure, a high knees exercise apparatus includes a base, two actuator members, and two pedals. The base includes a supporting member and a pivot portion. The pivot portion adjacent to the supporting member and has a pivot axis. The actuator members are pivotally connected to two sides of the pivot portion respectively and moving in response to each other reversely. Each of the actuator members includes a lower portion swinging along an arc path centered on the pivot axis. The arc path includes a first arc extended from a virtual vertical line passing through the pivot axis and an angle of the first arc is 45 degrees to 100 degrees. Each of the pedals is pivotally connected to a free end of each of the lower portions. The supporting member is disposed between the actuator members.
According to another aspect of the present disclosure, a high knees exercise apparatus includes a base, two actuator members, two pedals, a flywheel, and a resistance unit. The base includes a supporting member, a pivot portion, and a holder. The pivot portion is adjacent to the supporting member and has a pivot axis. The holder is located in front of the supporting member. The actuator members are pivotally connected to two sides of the pivot portion respectively and moving in response to each other reversely. Each of the actuator embers includes a lower portion and an upper portion. The lower portion swings along an arc path centered on the pivot axis. The arc path includes a first arc extended from a virtual vertical line passing through the pivot axis and an angle of the first arc is 45 degrees to 100 degrees. The upper portion is linked up with the lower portion and one end of the upper portion is provided with a hand grip which is flexible. A first included angle is formed between the lower portion and the virtual vertical line. A second included angle is formed between the upper portion and the virtual vertical line. The first included angle is 50 degrees to 60 degrees, and the second included angle is 20 degrees to 60 degrees. Each of the pedals is pivotally connected to a free end of each of the lower portions. The flywheel is attached to the base for stabilizing a moving speed of the actuator members and a weight of the flywheel is 0.1 kg to 5 kg. The resistance unit is attached to the base for imposing a resistance on the flywheel. The supporting member is disposed between the actuator members.
The disclosure can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
The base 110 includes a supporting member 111, a pivot portion 112, and a holder 113. The pivot portion 112 is adjacent to the supporting member 111 and has a pivot axis X′. The holder 113 is located in front of the supporting member 111. The actuator members 120 are pivotally connected to two sides of the pivot portion 112 respectively and the supporting member 111 is disposed between the actuator members 120. Each of the actuator members 120 includes an upper portion 121 and a lower portion 122. The upper portion 121 is linked up with the lower portion 122. Specifically, the upper portion 121 of the actuator member 120 will move in response to movement of the lower portion 122 of the actuator member 120 and vice versa. In other words, no matter which one of the upper portion 121 and the lower portion 122 is driven to move, the other will move simultaneously. Thus, users can operate the actuator members 120 by driving the lower portion 122 or the upper portion 121. In addition, each of the pedals 130 is pivotally connected to a free end 122a of each of the lower portions 122, so that the foot of users can rest or be attached on.
On the other hand, the second arc R2 is connected to the first arc R1 and reversely extended from the virtual vertical line L. Specifically, the arc path R is divided into the first arc R1 and the second arc R2 by the virtual vertical line L. An angle of the second arc R2 is preferably greater than 0 degrees and at most 10 degrees. Thus, users can execute high knees exercise in a greater extent. The supporting member 111, for example, is a saddle or a backrest which users can sit on or lean against when operating the high knees exercise apparatus 100. Moreover, users can hold the holder 113 located in front of the supporting member 111 to get on the supporting member 111 or users can let their upper body lying on the holder 113 to facilitate stretch of legs for driving the lower portions 122 fully swings along the arc path R, especially along a path of the second arc R2.
The high knees exercise apparatus 100 further includes a flywheel 140 and a resistance unit 150. The flywheel 140 is attached to the base 110 for stabilizing a moving speed of the actuator members 120 that makes the swing of the actuator members 120 more smooth.
The resistance unit 150 is attached to the base 110 for imposing a resistance on the flywheel 140 that makes the inertia of the high knees exercise apparatus 100 can be decreased to almost zero. Thus, users will feel like no apparatus existed when executing high knees exercise by the high knees exercise apparatus 100. A weight of the flywheel 140 is preferably 0.1 kg to 5 kg and more preferably 3 kg. The resistance unit 150, for example, is a magnetic damper and so on.
The hand grip 121a is flexible and capable of adapting varied operated angle. In other words, the hand grip 121a will deform slightly with the operation of the actuator members 120 by users. Thus, the operation of the high knees exercise apparatus 100 is ergonomic. The hand grip 121a, for example, is made of polyurethane. The supporting member 111 is rotatable and can adapt the movement of users' hip when they execute high knees exercise that also makes the high knees exercise apparatus 100 ergonomic. Furthermore, when users lift their knees high by the high knees exercise apparatus 100 they can also swing their arms and spread their elbow and shoulder because the upper portion 121 is linked up with the lower portion 122. Thus, the coordination of users' hands and feet can be improved.
Specifically, in this embodiment, the hand grip 121a and the lower portion 122 are disposed on two planes respectively and the planes are parallel to each other. The included angle A1 is an angle between horizontal projections of the hand grip 121a and the virtual vertical line L. A projection direction of those horizontal projections is identical to an extending direction of the pivot axis X′. In other embodiments of the present disclosure, the hand grip 121a and the lower portion 122 can be disposed on one plane.
