EXERCISE APPARATUS

Abstract

A physical exercise equipment set may include an elongated connecting bar having two ends and each end having a threaded engaging hole; a plurality of weighted portions; and two or more dumbbells. Each dumbbell has a handle having an elongated threaded portion at each of two opposite ends, a pair of weighted units located at two opposite ends of the handle, and a securing unit to secure each weighted unit in a predetermined position on the handle. For each of the two dumbbells, one of the weighted portions is taken out from one side of the handle, and the threaded portion is inserted into and threadedly engaged with each of the two threaded engaging holes of the connecting bar to form a barbell.

Claims

2. The dumbbell of claim 1, wherein the securing unit is configured to move along the threaded portion to secure the weighted portion on the handle.

3. The dumbbell of claim 1, wherein the weighted portion has a through hole and is inserted into the handle from the threaded portion until one side of the weighted portion reaches a stopping edge on the handle, while the other side of the weighted portion is secured by the securing unit on the threaded portion.

4. The dumbbell of claim 1, wherein the weighted portion can be added on each side of the handle according to the user's preferences.

5. The dumbbell of claim 1, wherein when at least one of the threaded portion of handle is detached from the connecting bar of the barbell, and one weighted portion is added and secured to the detached threaded portion, the barbell can be transformed to at least one dumbbell.

DETAILED DESCRIPTION OF THE INVENTION

[0017] 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.

[0018] 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.

[0019] 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.

[0020] As used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” includes reference to the plural unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the terms “comprise or comprising”, “include or including”, “have or having”, “contain or containing” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. As used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.

[0021] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the embodiments. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

[0022] In one aspect, as shown in FIGS. 1 to 3, a dumbbell 100 may include a handle 110, a pair of weighted units 112 located at two opposite ends of the handle 110, and a securing unit 114 to secure each weighted unit 112 in a predetermined position on the handle 110. In one embodiment, the two weighted portions 112 can be identical and symmetrically disposed at the opposite ends of the handle 110. More specifically, the weighted portion 112 has a through hole 1121 and the handle 110 has an elongated threaded portion 1101 at two opposite ends, and the securing unit 114 is configured to move along the threaded portion 1101. The weighted portion 112 is inserted into the handle 110 from the threaded portion 1121 until one side of the weighted portion 112 reaches a stopping edge 1102 on the handle 110, while the other side thereof is secured by the securing unit 114 on the threaded portion 1101.

[0023] As shown in FIG. 2, once the weighted portion 112 is secured by the securing unit 114 on each side of the handle 110, the user can hold the handle 110 of the dumbbell 100 to exercise on either one hand or two hands. It is noted that the weighted portion 112 can be added on each side of the handle 110 according to the user's training plans and preferences.

[0024] As discussed above, when the user purchases one type of exercise apparatus, such as dumbbells, it is difficult for the user to change the existing exercise apparatus to another type to exercise other portions of the body. Likewise, when the user purchases a traditional barbell, it is also difficult to alter it to a smaller exercise equipment such as dumbbells.

[0025] In another aspect, as shown in FIG. 3, two dumbbells 100 can turn into a barbell 200 with a simple addition of an elongated connecting bar 120. More specifically, for each dumbbell 100, the user can first disengage the securing unit 114 from one side of the threaded portion 1101 and the weighted portion 112 can be taken out from the threaded portion 1101 of the handle 110. The connecting bar 120 has two ends and each end has a threaded engaging hole 1201 to threadedly engage with the threaded portion 1101 of the dumbbell 100.

[0026] As shown in FIGS. 3 to 5, after removing one weighted unit 112 from each of the dumbbells 100, the threaded portion 1101 can be inserted and threadedly engaged with the threaded engaging hole 1201 on each side of the connecting bar 120 to form the barbell 200. In one embodiment, as shown in FIG. 4, the weighted portion 112 can be added to each side of the barbell 200 according to the user's training plans and preferences.

[0027] 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 equivalent.
