WAIST FITNESS APPARATUS

Abstract

A waist fitness apparatus includes main body and a resilient cover. The main body has a base pivotally connected with a supporting board through an eccentric unit, and the base is used to distribute the weight of the user, so the main body can be stably disposed on the ground. The present invention is advantageous because the height of the supporting board is higher than the height of the knee height of an average adult, the user does not have to bend the knees when sitting on it to increase the comfortableness. Also, the supporting board can be dragged back to its original position by the cover when it is not in use, so the user does not have to adjust the supporting board.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.

[0028] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.

[0029] All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.

[0030] In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

[0031] In one aspect, referring to FIGS. 1 to 4, the present invention provides a waist fitness apparatus having main body (10) and a resilient cover (20), wherein the main body (10) has a base (11) pivotally connected with a supporting board (13) through an eccentric unit (12), and the base (11) is used to distribute the weight of the user, so the main body (10) can be stably disposed on the ground. With the eccentric unit (12), the supporting board (13) is disposed slightly higher than an average person's knee height. The resilient cover (20) has a top edge (21) and a bottom edge (22), which are engaged at an outer periphery of the supporting board (13) and the base (11) respectively. Namely, the cover (20) provides a full area coverage to isolate the eccentric unit (12) between the base (11) and the supporting board (13) from outside. Because of the resilient cover (20), the supporting board (13) can be guided to a fixed position when it is not used. In one embodiment, the supporting board (13) is provided for the user to sit on. In another embodiment, the supporting board (13) has a soft seat (14) for the user to sit on to increase the comfort level.

[0032] In a further embodiment, each of the bottom portion of the base (11) and supporting board (13) has a neck portion (111) and (131) respectively, so the bottom edge (22) and top edge (21) of the cover (20) can be secured on the neck portions (111) and (131). In still a further embodiment, the resilient cover (20) is a cloth cover.

[0033] The eccentric unit (12) has a first connecting rod (121) plugged into the top center portion of the base (11) and a second connecting rod (123) plugged into the bottom center portion of the supporting board (13). The first connecting rod (121) is upwardly protruding from the base (11) while the second connecting rod (123) is downwardly protruding from the supporting board (13). A curved connector (122) is configured to connect the protruding portions of the first connecting rod (121) and second connecting rod (123). Two rings (124) are disposed between the base (11) and the first connecting rod (121), and between the supporting board (13) and the second connecting rod (123). The first connecting rod (121), the second connecting rod (123), the curved connector (122), the rings (124) and the base (11) are forming a cone-shaped structure. In one embodiment, the size of the base (11) is different from that of the supporting board (13), and the size of the base (11) is slightly larger than the supporting board (13).

[0034] When in use, the supporting board (13) or the soft seat (14) are provided for the users to sit on, and the eccentric unit (12) and the base (11) are used to sustain the user's weight. Since the height of the supporting board (13) is higher than the average height of an adult's knee, so when the user sits on the supporting board (13), he/she does not have to bend the knees and both legs can fully extend (see FIG. 5). During the exercise, the user's legs can both be supported by the ground, so the user's lower body and waist can effectively drive the supporting board (13) to rotate (see FIGS. 6 and 7). When it is rotated, the curved connector (122) of the eccentric unit (12) can be more in a circulated manner according to the base (11) as an origin. The connection between the curved connector (122) and the supporting board (13) is through the second connecting rod (123), and the supporting board (13) is configured to rotate by itself on the curved connector (122) (see FIGS. 4, 17 and 18) to effectively reduce the shear force when the supporting board (13) rotates. Furthermore, with the rotation of the supporting board (13) on the second connecting rod (123), the supporting board (13) can always rotate toward one direction.

[0035] Comparing with conventional waist fitness apparatuses, the present invention is advantageous because (i) the height of the supporting board (13) is higher than the height of the knee height of an average adult, the user does not have to bend the knees when sitting on it to increase the comfortableness; (ii) the height of the supporting board (13) is higher than the height of the knee height of an average adult, the user does not have to bend the knees and the user's both legs can be supported by the ground to effectively drive the supporting board using the lower body to avoid sports injuries; (iii) the supporting board (13) can be dragged back to its original position by the cover (20) when it is not in use, so the user does not have to adjust the supporting board (13); (iv) the use of the cover (20) can prevent the eccentric unit (12) from dust or other external objects; and (v) when the fitness apparatus is in use, both legs of the user are supported by the ground, so it is unnecessary to install other equipment such as hand rails.

[0036] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
