Patent Description:
The present invention is directed to support systems for the automatic retraction of dumbbell and barbell arm assemblies when a user performs an exercise using the barbell or dumbbells.

Strength training systems are generally used to build strength and improve the endurance of a user. The activities typically associated with strength training include the use of resistance, often in the form of weights, to cause the muscles of a user to contract, increasing the strength of the muscles and the function of associated tendons, ligaments, and joints.

Exercises may include those with free weights, such as barbells and dumbbells, where a user controls the motion or location of these weights over a period of time or for a number of sets and repetitions. Different exercises are often undertaken to strengthen various muscle groups. While performing exercises with free weights, a user may undertake movements that are unconstrained by support equipment and thus a user often desires to perform such movements in an environment clear of equipment. In typical strength training systems with free weights, a user removes the weight or weights from a weight support structure by himself or with the assistance of another person and then must reposition the weights or the user's body in order to undertake the intended exercise. This process for barbells then is reversed when the user wishes to store the weight or weights in the weight support structure. This process for dumbbells typically begins by picking the dumbbells up from the floor and then returning the dumbbells to the floor following use.

The present invention allows a user to perform exercises with free weights without having to reposition or move the user's body from the weight support structure. At an accessible distance from the weight support system, the user may access dumbbells or a barbell, place them in the cradles and extend the extendable arm assemblies. The extendable arm assemblies are moved to the extension position from the retracted position to deliver the dumbbells or barbell. When the dumbbells or barbell are unloaded from the extended arm assemblies, the extendable arm assemblies automatically retract to steer clear the line of action of exercise. Therefore, the system enables the user to perform the exercise without having to move away from the system or seek the help of others to grab and lift the dumbbell or barbell weights. The retraction of the extendable arm assemblies is sufficiently close to the user, such that the user can replace the dumbbells or barbell back onto the cradle without the help of others. <CIT> shows an apparatus for storage and presentation of exercise dumbbells.

According to the invention, the problem posed is solved by the features of claim <NUM>.

In some instances, the arm assembly includes a first arm and a second arm, each of the first arm and the second arm being pivotally coupled to the base. The apparatus may further include a strut assembly coupled to and between the first arm and the second arm, the strut assembly being configured for forcing the cradle to pivot from the first position to the second position. In some instances, the apparatus further includes a vertically arranged connection plate to which the base is coupled, the connection plate being configured for selectively attaching to the support frame. In some instances, the apparatus further includes a first hinge arm pivotally coupled to the connection plate, a second hinge arm pivotally coupled at one end thereof to the arm assembly and hingedly coupled to the first hinge arm at a second end thereof, and a spring assembly coupled to and between the base and the second end of the second hinge arm. The apparatus may further include a roller arm having a first end portion pivotally coupled to the arm assembly and a second end portion supporting a rotatable member, the support frame being arranged between the rotatable member and the arm assembly.

In some instances, the cradle is pivotally coupled to the pivot arm and the first force is exerted on the pivot arm by a strut. In other instances, the first force is exerted on the pivot arm by a spring. In yet other instances, the first force is exerted on the pivot arm by a downwardly-curved arm coupled to and between the pivot arm and a rotatable member wherein the frame arm is located between the pivot arm and the rotatable member.

A further understanding of the nature and advantages of the present invention will be realized by reference to the remaining portions of the specification and the drawings.

The present disclosure same can be better understood, by way of example only, with reference to the following drawings. The elements of the drawings are not necessarily to scale relative to each other, emphasis instead being placed upon clearly illustrating the principles of the disclosure.

However, in other embodiments, there may be other configurations to facilitate the handling of extendable arm assemblies 120R, <NUM>.

In the depicted embodiment, cradle handle bracket <NUM> is coupled to lower cradle frames 142R, <NUM>, to the outside of lower cradle frames 142R, <NUM>, and cradle handle <NUM> is assembled such that grip <NUM> points towards the inside of frame <NUM>, and bottom arm bracket <NUM> is coupled to resting plate <NUM> such that it points towards the outside and is assembled to facilitate coupling of bottom arm bracket handle <NUM> towards the outside of frame <NUM>. These are configured to facilitate both the right hand side and the left hand side respectively of system <NUM> in performing two-handed dumbbell exercises in many scenarios.

<FIG> depicts system <NUM> at extension position <NUM> and <FIG> depicts system <NUM> in retracted position <NUM> of assemblies 120R, <NUM>. In the depicted embodiment, assemblies 120R, <NUM> are extended along with dumbbell <NUM> on cradles 138R, <NUM> wherein when dumbbell <NUM> is placed on system <NUM> at retracted position <NUM>, the load of dumbbell <NUM> is supported by frame <NUM>. Further, assembly 120R, <NUM> is configured to be moved by the user away from frame <NUM>. As assembly 120R, <NUM> is moved, strut <NUM>, initially in expanded strut position <NUM>, starts compressing, until assembly 120R, <NUM> reaches its extension position <NUM>, and assembly 120R, <NUM> is unable to be extended further. In extension position <NUM> of assembly 120R, <NUM>, the load of dumbbell <NUM> is acting on strut <NUM> and assembly 120R, <NUM> stays in extension position <NUM> as long as dumbbell <NUM> is placed in assembly 120R, <NUM>. When dumbbell <NUM> is lifted from system <NUM>, strut <NUM> reverts to expanded strut position <NUM> and thereby assemblies 120R, <NUM> retract to retracted position <NUM>.

System <NUM> has parts that can and will be used on both left and right sides of the system. Additionally, system <NUM> has parts that must only be used on the side it was designed for, either the left side or the right side. Right side only parts are 138R, 140R and 142R. Left side only parts are <NUM>, <NUM> and <NUM>. All other parts are designed to be used on both the left and right hand sides.

Dumbbell support system <NUM>, as depicted in <FIG>, is designed to move in a multitude of directions in order to fully facilitate the use of two-hand dumbbells. System <NUM> has a left side and a right side that move independently. The individual right and left sides provide a unique ability to traverse the Z plane independent of each other. The individual right and left sides provide a unique ability to traverse the X plane independent of each other. The individual right and left sides are height-adjustable, providing a unique ability to traverse the Y plane independent of each other. The individual right and left side design includes a base with unique linking support elements <NUM> to allow close proximity to the user throughout the Z plane of motion. The individual right and left side design allows specific placement of either the left side or the right side per the requirements of the user. For instances an arm amputee with a prosthetic arm could require a variance for one side or the other as well, as could many other users that have specific needs.

In <FIG>, a second embodiment not according to the invention is shown as the first barbell support system <NUM>. In an exemplary embodiment of the invention, system <NUM> comprises a pair of extendable first barbell arm assemblies 208R, <NUM> attached to first barbell support frames <NUM>. The pair of first barbell arm assemblies 208R, <NUM> are identical in most cases. System <NUM> is intended to be an improvement to or an attachment to preexisting weight bench presses of all types, as well as weight lifting racks of all types and weight machines of all types, but not to exclude any devices that could be made in the future. First barbell arm assemblies 208R, <NUM> comprise first barbell arm cradles <NUM>, to hold a barbell <NUM>. In such an embodiment, barbell <NUM> is placed on first barbell arm assemblies 208R, <NUM>, which are extended to a distance away from the frame (referred to as the first barbell extension position <NUM>). Barbell <NUM> is supported by system <NUM> at first barbell extension position <NUM>. Furthermore, when barbell <NUM> is removed from system <NUM> at extension position <NUM>, first barbell arm assemblies 208R, <NUM> retract back to first barbell support frame <NUM> (referred to as the first barbell retracted position <NUM>). Barbell <NUM> is supported at first barbell retracted position <NUM>.

For example, when a user, at an accessible distance from system <NUM>, performs exercises, the user places barbell <NUM> in first barbell arm cradle <NUM> while first barbell arm assemblies 208R, <NUM> are at retracted position <NUM>. The user extends first barbell assemblies 208R, <NUM> to first barbell extension position <NUM> to deliver barbell <NUM>. When the user begins the exercise, barbell <NUM> is unloaded from first barbell arm assemblies 208R, <NUM> and automatic retraction of first barbell arm assemblies 208R, <NUM> clears the line of action of exercise. Therefore, system <NUM> enables the user to perform the exercise without having to move away from system <NUM> or seek the help of others to grab and lift barbell <NUM>. The retraction of first barbell arm assemblies 208R, <NUM> is at a distance such that the user is capable of replacing barbell <NUM> back onto first barbell arm cradles <NUM> without the help of others.

First barbell arm <NUM>, as depicted by <FIG>, is configured to enable the pivoting function of first barbell arm assemblies <NUM>, wherein first barbell arm <NUM> is configured to toggle between first barbell extension position <NUM> and first barbell retracted position <NUM>. First barbell arm <NUM> pivots about the pivot axis B-B, where first barbell arm <NUM> is connected with first barbell holder <NUM>. First barbell arm <NUM> has a plurality of first barbell arm holes <NUM> on its surface for coupling purposes and first barbell arm <NUM>, and includes first barbell arm cradle <NUM> at the top portion of first barbell arm <NUM>. First barbell arm cradle <NUM> is configured to hold barbell <NUM>.

Further, in the depicted embodiment, first barbell arm cradle <NUM> has a raised lip angled outward from first barbell arm cradle <NUM>. However, in other embodiments, other shapes, sizes, and configurations of first barbell arms <NUM> and first barbell arm cradles <NUM> are possible.

As depicted by <FIG> and <FIG>, one or more first barbell elbow plates <NUM>, <NUM>, extension spring <NUM> and first barbell connecting plate <NUM> of first barbell arm assembly <NUM> are configured to partially constrain the pivot motion of first barbell arm <NUM> about first barbell holder <NUM>. One or more first barbell elbow plates <NUM>, <NUM> are connected between first barbell resting plate <NUM>, first barbell arm <NUM>, and first barbell connecting plate <NUM>. First barbell elbow plates <NUM>, <NUM> include one or more holes to facilitate coupling. An upper end of first barbell elbow plate <NUM> is hinged to first barbell resting plate clamping provision <NUM>, and an upper end of first barbell elbow plate <NUM> is hinged to first barbell arm <NUM>. The lower end of first barbell elbow plates <NUM>, <NUM> are hinged together to a top end of first barbell connecting plate <NUM>. As first barbell arm <NUM> pivots, on account of weight acting on system <NUM>, first barbell elbow plate <NUM> deflects in the direction of first barbell arm <NUM>, and consequently first barbell elbow plate <NUM> deflects in the opposite direction. The deflection of first barbell elbow plates <NUM>, <NUM> reaches a position after which first barbell elbow plates <NUM>, <NUM> do not deflect further, denoting a first barbell elbow plate extension position <NUM> (<FIG>, right) and prevents further pivot motion of first barbell arm <NUM> about pivot axis B-B. When load is removed, first barbell elbow plates <NUM>, <NUM> reach a first barbell elbow plate retracted position <NUM>, after which first barbell elbow plates <NUM>, <NUM> are as close to vertically oriented as possible (<FIG>, left). This position prevents further pivot motion of first barbell arm <NUM> about pivot axis B-B toward first barbell support frame <NUM>. In the depicted embodiment, first barbell elbow plates <NUM>, <NUM> are connected to first barbell resting plate <NUM>, first barbell arm <NUM>, and first barbell connecting plate <NUM> through one or more threaded bolts and nuts. In some embodiments, first barbell elbow plates <NUM>, <NUM> are integrally constructed with first barbell arm assembly <NUM>. In some embodiments, first barbell elbow plates <NUM>, <NUM> re permanently or semi-permanently coupled. In other embodiments, other configurations of first barbell elbow plates <NUM>, <NUM> with other coupling mechanisms are possible.

First barbell connecting plate <NUM> of first barbell arm assembly <NUM>, as depicted by <FIG> and <FIG>, is configured to connect extension spring <NUM> with first barbell elbow plates <NUM>, <NUM> and transfer the weight acting on system <NUM> to extension spring <NUM>. First barbell connecting plate <NUM> includes one or more first barbell connecting plate holes <NUM> for coupling purposes, wherein the top end of first barbell connecting plate <NUM> is connected to first barbell elbow plates <NUM>, <NUM>, as described above and at the bottom end of first barbell connecting plate <NUM> is connected to extension spring <NUM>. As first barbell elbow plates <NUM>, <NUM> deflect, first barbell connecting plate <NUM> undergoes a linear motion with respect to its connection points. In the depicted embodiment, first barbell connecting plate <NUM> is a rectangular plate, although in other embodiments other shapes and sizes of first barbell connecting plate <NUM> are possible. Moreover, in the depicted embodiment, first barbell connecting plate <NUM> includes a first barbell connecting plate threaded fastener <NUM> on the top end of first barbell connecting plate <NUM>, to be coupled with first barbell elbow plates <NUM>, <NUM>, and first barbell connecting plate <NUM> is connected to extension spring <NUM> by threaded bolts and nuts. In some embodiments, first barbell connecting plate <NUM> is integrally constructed with first barbell arm assembly <NUM>. In other embodiments, other configurations, shapes, and sizes of first barbell connecting plate <NUM> and other coupling mechanisms are possible.

Extension spring <NUM>, depicted by <FIG> and <FIG>, is configured to oppose extension of system <NUM> and is configured to bring first barbell arm assembly <NUM> to first barbell retracted position <NUM>. Extension spring <NUM> includes a plurality of extension spring coils <NUM>, an upper extension spring hook <NUM>, and a lower extension spring hook <NUM>. The plurality of extension spring coils <NUM> is configured to perform elongation and contraction function of extension spring <NUM>, whereas upper extension spring hook <NUM> and lower extension spring hook <NUM> are configured to facilitate attachment of other parts with extension spring <NUM> and transfer the weight to extension spring coils <NUM>. Extension spring coils <NUM> are wound tightly to each other with initial tension. Upper extension spring hook <NUM> is coupled to first barbell connecting plate <NUM>, as described above and lower extension spring hook <NUM> is connected to holder shaft <NUM> by inserting lower extension spring hook <NUM> around holder shaft <NUM>. In an exemplary embodiment, as the weight is acting on the system, the load is transferred to extension spring coils <NUM> and extension spring <NUM> elongates when the initial tension of extension spring <NUM> is overcome by the weight acting on extension spring <NUM>, enabling first barbell arm <NUM> to pivot to first barbell extended position <NUM>. First barbell arm <NUM> stays in first barbell extended position <NUM> until barbell <NUM> is removed from system <NUM>. Once the weight is removed, extension spring <NUM> returns to the original position of extension spring <NUM>, and thereby first barbell arm <NUM> retracts to first barbell retracted position <NUM>. The parameters of extension spring <NUM> are chosen, such that extension spring <NUM> is able to bear the load of system <NUM>.

Now referring to <FIG>, prospective views of first barbell extended position <NUM> and retracted position <NUM> of system <NUM> are depicted. In the depicted embodiment, first barbell assemblies 208R, <NUM> are extended along with barbell <NUM> on first barbell arm cradles <NUM>, wherein when barbell <NUM> is placed in system <NUM> in first barbell retracted position <NUM>, first barbell assemblies <NUM> are extended by the user, away from first barbell support frame <NUM>. As first barbell assemblies <NUM> are extended, first barbell arms <NUM> pivot about pivot axis B-B, and consequently first barbell elbow plates <NUM>, <NUM> start deflecting, with first barbell connecting plate <NUM> translating upwards and transferring the load to extension spring <NUM>, thereby elongating extension spring <NUM>. When first barbell elbow plates <NUM>, <NUM> reach first barbell elbow plate extended position <NUM>, extension spring <NUM> cannot elongate further, and thereby the pivot motion of first barbell arm <NUM> stops. Consequently, further extension of first barbell arm assemblies <NUM> is not possible, indicating first barbell extension position <NUM>. Further, in the depicted embodiment, the elongation of extension spring <NUM> stops when the load acting on extension spring <NUM> is not sufficient to create further elongation in extension spring <NUM> or when first barbell elbow plates <NUM>, <NUM> reach first barbell elbow plate extended position <NUM>.

When the user grabs and lifts barbell <NUM> from system <NUM>, the tension force required to overcome the initial tension of extension spring <NUM> is absent, retracting extension spring <NUM> to its original position. Hence, first barbell connecting plate <NUM> translates downwards, first barbell elbow plates <NUM>, <NUM> trace the deflection path back, and first barbell arm <NUM> pivots back to first barbell retracted position <NUM>.

Referring now to <FIG>, there is presented a third embodiment not according to the invention with second barbell support system <NUM>. In an exemplary embodiment of the invention, system <NUM> comprises a pair of extendable second barbell arm assemblies 306R, <NUM> attached to second barbell support frames <NUM>. Second barbell arm assemblies 306R, <NUM> are identical in most cases. System <NUM> is intended to be an improvement to or an attachment to preexisting weight bench presses of all types, as well as weight lifting racks of all types and weight machines of all types, but not to exclude any devices that could be made in the future. Second barbell arm assemblies <NUM> comprise second barbell arm cradles <NUM>, to hold barbell <NUM>. In such an embodiment, barbell <NUM> is placed on second barbell arm assemblies <NUM>, which are extended to a distance away from second barbell support frame <NUM> (referred to as the second barbell extension position <NUM>). Barbell <NUM> is supported by system <NUM> at second barbell extension position <NUM>. Furthermore, when barbell <NUM> is removed from system <NUM> at second barbell extension position <NUM>, second barbell arm assemblies <NUM> retract back to second barbell support frame <NUM> (referred to as the second barbell retracted position <NUM>). Barbell <NUM> is supported at second barbell retracted position <NUM>.

For example, when a user, at an accessible distance from system <NUM>, performs exercises, the user places barbell <NUM> in second barbell arm cradles <NUM>, while second barbell arm assemblies <NUM> are at second barbell retracted position <NUM>. The user extends second barbell assemblies <NUM> to second barbell extension position <NUM> to deliver barbell <NUM>. When the user begins the exercise, barbell <NUM> is unloaded from second barbell arm assemblies <NUM>, and automatic retraction of second barbell arm assemblies <NUM> clears the line of action of exercise. Therefore, system <NUM> enables the user to perform the exercise without having to move away from system <NUM> or seek the help of others to grab and lift barbell <NUM>. The retraction of second barbell arm assemblies <NUM> is a distance such that the user is capable of replacing barbell <NUM> back onto second barbell arm cradle <NUM> without the help of others.
