BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to an exercise machine, more particularly to a portable exercise apparatus with wearable anchor arrangement, wherein the wearable anchor arrangement is adapted for being worn on a predetermined portion of a user to functionally serve as an anchor point for the user to conduct strength training exercise with resistance element.

Description of Related Arts

The use of exercise machine has proliferated in the last decades. In general, there are two main classifications of such machines: those primarily intended for resistance training and those primarily intended for weight training. Those intended primarily for weight training utilizes the force of gravity in the form of weighted bars, dumbbells or weight stacks in order to oppose the force exerted by the muscle contraction. Those intended primarily for resistance workouts includes a resistance element such as elastic band which is attached to an anchor for being repeatedly stretched and unstretched by a user to exercise his legs, arms or body during workouts. Compared with weight-based training, the resistance-based training is much safer because there is typically less chance causing injury. Therefore, many exercisers prefer resistance-based training especially when they are working out at home or in a place where no professional trainer is accompanied.

Previous apparatus used for resistance workouts are commonly complicated and unwieldy and susceptible to many limiting constraints. Typically, many constraints, such as portability of the device, the lack of personalization to individual skill levels, and lack of versatility in changing training gestures, are associated with the anchor apparatus.

The anchor apparatus to which the resistance elements are attached is configured for providing a countervailing force for the exerciser to oppose against by muscle contractions during workouts. There are two main types of anchor apparatus, one of which is an immobile platform commonly seen in a training center. One or more resistance elements are bonded to the immobile platform to form one or more anchor points for allowing the exerciser to repeatedly stretch and unstretch one or more resistance elements relative to the anchor points respectively so as to strengthen his or her muscles. Such immobile platforms commonly have bulky parts and resistance elements can only be incorporated in a limited number of directions.

Another type of anchor apparatus is a portable platform mainly for home use. Still, the portable platform is also required to be immobile during workouts, i.e. by fixing it to a secure structure, applying weight to the platform, by the exerciser applying weighs to the platform through a body part or standing on it.

As the portable platform is secured to an immobile structure, the exercise area for the user to move is substantially limited by the length and elasticity of the elastic band. In other words, some training gestures requiring the user to move in a wider range are not permitted due to the immobile anchor apparatus. In addition, if the portable platform is rendered immobile by the user standing on it or applying pressure though a body part himself or herself, the respective body port is required to keep still for applying pressure against the platform, such that the training gestures are more severely constrained.

In a typical training program, a set of training gestures are commonly involved for the exerciser to conduct. It is unfortunately to find out that the exerciser has to compromisedly simplify his training program to trade off a bad training effectiveness. In other words, conventional anchor apparatus lacks versatility in its integration into a training program.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Referring to FIGS. 1-15 of the drawings, an exercise apparatus 100 according to a preferred embodiment of the present invention is illustrated, which is a portable exercise apparatus 100 provided for a user to conduct strength training using resistance elements 20 at home, at the gym, in an office area or in the outdoors.

To provide resistance for strength training, one or more resistance elements 20, such as elastic bands made of rubber or the like, are securely attached to an anchor when conducting resistance training using resistance elements 20. However, conventional immobile anchor apparatus would, to some extent, limit the user to change his training gestures freely in a training program.

In the present invention, a wearable anchor arrangement 10 is provided which is not only able to overcome the shortcomings in the conventional anchor structures, but also brings some unexpected advantageous to be described later.

Accordingly, as shown in the FIG. 1 of the drawings, the exercise apparatus 100 in the present invention comprises a wearable anchor arrangement 10 adapted for being worn around a predetermined portion of an user body, embodied as an ankle portion 70 of the user body, to serve as an anchor point, one or more human interface mechanisms 30, and one or more resistance elements 20, each having a first end 201 and a second end 202, wherein the first end 201 of the resistance element 20 is coupled to the wearable anchor arrangement 10 and the second end 202 thereof is coupled to the human interface mechanism 30, such that the user is able to repeatedly stretch and unstretch the resistance elements 20 with respective to the anchor point defined by the wearable anchor arrangement 10 by applying pressure to the human interface mechanisms 30.

In particular, the human interface mechanism 30 is exemplarily embodied as a workout bar 30A having an elongated structure according to the preferred embodiment of the present invention. Accordingly, a pair of the wearable anchor arrangements 10 are provided to retain around a left ankle portion 70 and a right ankle portion 70′ of the user body respectively to serve as two anchor points for removably coupling a pair of resistance elements 20 respectively which in turn couple to two end portions of the workout bar 30A. Then, the user is able to stretch the resistance elements 20 with respective to the anchor points by lifting up the workout bar 30A to workout and strengthen his body.

It is well known in the art that different muscles or muscle groups can be trained in different training gestures. Typically, an exerciser is preferred to change his or her training gestures in a scientific training program. In the present invention, the wearable anchor arrangement 10 is fittedly worn around the ankle portion 70 to serve an anchor point for coupling its respective resistance element 20, such that all body parts of the exerciser are freed to make movements in all directions and ranges. In other words, with the wearable anchor arrangement 10, the exerciser is allowed to change his or her training gestures more freely, since all body parts of the user are freed and not required to apply a pressure against the portable platform as in the prior art.

Accordingly, the wearable anchor arrangement 10 comprises a first retaining strap 11 having a predetermined length, a first fastener 12, a second retaining strap 13 integrally extended from the first retaining strap 11, and a second fastener 14. The first fastener 12 is arranged to incorporate with the first retaining strap 11 to form a first retaining loop 11′ for encirclingly holding around the ankle portion 70 of the user body at an upper side thereof, and the second fastener 14 is provided on the first retaining strap 11 and arranged to incorporate with the second retaining strap 13 to form a second retaining loop 13′ for encirclingly holding around the ankle portion 70 of the user body at the lower side thereof, such that the wearable anchor arrangement 10 is wrappedly retained around the ankle portion 70 of the user body to serve as an anchor point of the user body for the user to conduct strength training exercises through the resistance elements 20.

Referring to FIG. 2 of the drawings, the first retaining strap 11 has an elongated shape with a length substantially equal with or somewhat less than an ankle circumference of the exerciser. The first fastener 12 comprises a first connecting element 121 and a second connecting element 122, wherein the second connecting element 122 is arranged to fasten with the first connecting element 121 to lock up two ends of the first retaining strap 11 to form the first retaining loop 11′ for encirclingly holding around the ankle portion 70 at the upper side thereof.

More specifically, in the preferred embodiment, the first connecting element 121 is outwardly extended from one side edge of the first retaining strap 11 to form as an elongated strap, and the second connecting element 122 is provided at the same side edge of the first retaining strap 11. In particular, the first connecting element 121 has a length larger than the ankle circumference and arranged to fold along the upper side of the ankle portion 70. Accordingly, when the first retaining strap 11 is bent and attached to the upper side of the ankle portion 70, the first connecting element 121 is arranged to circle around the first retaining strap 11 for a circle from one side edge of the first retaining strap 11 back to the same side edge and to fasten with the second connecting element 122 to form a locking mechanism. As the first connecting element 121 is fastened with the second connecting element 122, the two ends of the first retaining strap 11 are locked up to form the first retaining loop 11′ around the upper side of the ankle portion 70 of the user body. Preferably, the first connecting element 121 is integrally extended from one side edge of the first retaining strap 11 from a mid portion thereof.

It is worth mentioning that the first connecting element 121, having a length larger than an ankle circumference, is overlapped with the first retaining strap 11 for a circle to fasten with the second connecting element 122. In other words, two layers of straps (the first retaining strap 11 and the first connecting element 121 forming as an elongated strap) are encircled around the ankle portion 70 of the user body at the upper side thereof, in such a manner that the tightness between the first retaining loop 11′ and the ankle portion 70 is increased by the first connecting element 121 to secure its function as an anchor. Moreover, the ankle portion 70 of the user body would get well-protected and more comfort when being wrapped by the two strap layers.

FIG. 3 illustrates a first alternative mode of the first fastener 12 according to the preferred embodiment of the present invention. As shown in FIG. 3, the first connecting element 121A is outwardly extended from one side edge of the first retaining strap 11 to form as an elongated strap, and the second connecting element 122A is provided at the opposed side edge of the first retaining strap 11, wherein when the first retaining strap 11 is folded along the upper side of the ankle portion 70, the first connecting element 121A is flapped from one side edge to the opposed side edge of the first retaining strap 11 and to fasten with the second connecting element 122A so as to lock up the two ends of the first retaining strap 11, which in turn forms the first retaining loop 11′A around the upper side of the ankle portion 70 of the user body. Preferably, the first connecting element 121A is integrally extended from one side edge of the first retaining strap 11A from a mid portion thereof.

In order to securely and adjustably retain the first retaining loop 11′A around the upper side of the ankle portion 70, the first fastener 12A may be able to be fastened to selectively adjust a size (a diameter) of the first retaining loop 11′A. For instance, the second connecting element 122A may have an elongated structure provided on the same side edge of the first retaining strap 11 and extended inwardly along a mid-line of the first retaining strap 11, such that the second connecting element 122A is able to selectively and partially fasten with the first connecting element 121A in order to adjust a size of the first retaining loop 11′A to better fit the first retaining loop 11′A around the upper side of the ankle portion 70. In other words, the length of the first retaining loop 11′A can be selectively adjusted to fit the ankle portion 70 in any size of the exerciser.

Alternatively, another second connecting element 122A may further be provided at a position spaced from the original second connecting element 122A along the mid-line of the first retaining strap 11, such that the first connecting element 121A is able to selectively coupled with any one of the second connecting elements 122A so as to adjust a size of the first retaining loop 11′A with respective to the size of the ankle portion 70 of the body of a particular exerciser.

After the resistance elements 20 are coupled to the wearable anchor arrangements 10 worn around the ankle portions 70 of the exerciser, the other end 202 of respective resistance element 20 is arranged to couple with the workout bar 30A at two end portions thereof respectively via a fastening mechanism. For instance, a pair of coupling rings may be provided on the two end portions of the workout bar 30A for detachably coupling with the attaching members 21 on the other end 202 of the resistance elements 20 respectively.

With the wearable anchor arrangement 10 worn around the ankle portions 70 of the user body and resistance elements 20 extending between the wearable anchor arrangement 10 and the workout bar 30A, the exerciser is able to lift up the workout bar 30A by stretching his arms in a direction against the resistance force generated by the stretched resistance element 20 in order to train his arms. Moreover, the exerciser is allowed to change his training gestures either by selectively coupling the resistance element 20 to a coupling member 15 at a different position of the wearable anchor arrangement 10, or changing the poses of his or her ankle portion 70. Further, the exerciser is allowed to vary the resistance levels simply by adopting a resistance element 20 with a different length or increasing or decreasing the number of the resistance elements 20 to a same coupling member 15 of the wearable anchor arrangement 10 during workouts.

It is worth mentioning that during workouts, the exerciser may also choose to attach the other end 202 of the resistance element 20 to an immobile structure 40 to form another anchor point, such that the exercise is allowed to stretch his legs to oppose against the resistance force produced by the stretched resistance element 20. For instance, the immobile structure 40 may be a training machine with bulky parts including wheels, weights, pulleys, and etc, or simply any immobile construction within the sight of the exerciser as shown in the FIG. 10 and FIG. 11 of the drawings.
