System for linking dumbbells to increase the weight lifted by a user

Abstract

The present invention is a device configured to permit combining the weight of a first and second free weight such that a user could grasp one of the weights in order to lift the combined weights. Embodiments of the invention comprise a back panel connected to two side panels, the side panels each comprising a slot with an opening divided into two portions oriented such that a first free weight may be inserted into the slot of each panel and positioned into a first slot portion, followed by a second free weight positioned in the second slot portion of each panel to permit a user to increase the resistance available for an exercise regimen.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

(6) Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

(7) Referring to FIG. 1, an embodiment of the invention is illustrated that is formed from a left panel 102, a right panel 104, and a connector panel 106. As is illustrated, the connector panel may be affixed to the left 102 and right 104 panels using a plurality of fasteners 108. As illustrated, this may be nuts and bolts, but also may be other fasteners, including, but not limited to, rivets and welds. Additionally, embodiments of the invention may be formed from a single sheet of rigid material cut and formed to approximate what is illustrated in FIG. 1.

(8) As illustrated, the left 102 and right 104 panels comprise a slot 110 that extends from a point near the top of the side panel to near the bottom of the side panel. The slot 110 comprises an opening 112 and an upper 114 and lower 116 hook structure. FIG. 2 illustrates a side view of an exemplary side panel. As shown, a slot 110 may extend from the opening 112 upward to an upper hook 114 and downward to a lower hook 116. As illustrated in FIG. 3, a first weight 302 may be installed in an embodiment of the invention such that the handle 304 of the weight is located in an upper hook structure 114 of each side panel. As shown, the handle 304 is located in the slot 110 and retained in the slot by the front portion of the upper hook 114. Once a first weight is installed in an embodiment of the invention, a second weight 306 may be inserted into the invention such that the handle 308 of the second weight 306 is captured by the lower hook structure 116.

(9) As illustrated in FIG. 4, the first weight 302 and second weight 306 are captured by the upper and lower hooks. A user may grasp the handle 304 of the first weight and lift the first weight 302, the second weight 306, and the invention 402. As a result, the user will be lifting the combined weight of both weights and the invention. Thus, the invention may allow a user to combine dumbbell weights such that the user may not be required to purchase or own dumbbells that, standing alone, have the combined weight of the first and second weights as illustrated in FIG. 4.

(10) In certain embodiments of the invention, an opening may be provided for a strap 404 to secure the second weight 306 into an embodiment of the invention. Such an opening is illustrated in FIG. 1 at 112. In addition to the openings shown, other openings may be formed in various other portions of the connector panel 106. In such an embodiment of the invention, a strap 404 may be inserted into the opening and wrapped around the handle 308 of the second weight 306 to secure it in place. As secured, the weight is less likely to slide along the slot 110 where it could make contact with the first weight 302. The use of such a strap 404, while not necessary, may reduce the likelihood of a user being pinched or otherwise injured by a weight shifting in an embodiment of the invention. In other embodiments of the invention, a ring or other method of securing a strap may be affixed to a portion of the invention.

(11) In order to use an embodiment of the invention, a user may place the handle portion 304 of a first dumbbell 302 into the opening 112 between the upper and lower hook structure. The user may then move the handle along the slot 110 until the handle reaches an end of the slot. In the illustrated embodiment the user is required to move the first dumbbell to the upper hook 114 in order to provide access for a second weight. The user may then place a second dumbbell 306 into the opening 112 and move that dumbbell the opposite direction of the first dumbbell to the lower hook 116. When the second dumbbell is in place in the lower hook, a user may grasp the handle 304 of the first dumbbell 302 in a manner similar to how the handle would be grasped if the first dumbbell were not installed in the invention. When the user grasps the handle 304 and lifts, the invention will cause the upper hook to catch on the handle 304 of the dumbbell being lifted and cause the second dumbbell 306 to be raised as well. Thus, the user is raising both the first and second dumbbells, effectively combining their weights. If the user is using a strap 404 to secure the dumbbell, the user may wrap the strap around the second dumbbell handle portion 308 prior to lifting the combined weights.

(12) Any embodiment of the present invention may include any of the optional or preferred features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. Having shown and described exemplary embodiments of the present invention, those skilled in the art will realize that many variations and modifications may be made to the described invention. Many of those variations and modifications will provide the same result and fall within the spirit of the claimed invention. It is the intention, therefore, to limit the invention only as indicated by the scope of the claims.
