Embodiments herein relate to exercise or fitness equipment. In some examples, exercise or fitness equipment may include weightlifting devices such as dumbbells and barbells. In some embodiments, the present disclosure relates generally to attachments, devices, and/or apparatuses for use in weightlifting.
The benefits of exercise and physical activity are well-known. Exercise is important for physical health, longevity, and general well-being.
It follows that exercise and fitness equipment that can facilitate such activity can add value to the lives of many. In order to facilitate many forms of exercise and fitness activity, specialized equipment exists.
A wide range of exercise and fitness equipment options are available on the market today. However, with these increased choices has come interoperability and adaptability issues. Further, the problem of equipment storage grows when various equipment needs arise.
One form of exercise that often makes use of specialized equipment is strength training. For example, many devices exist for weightlifting. A large number of weightlifting devices such as dumbbells, barbells, and bars have been created. With them, some weightlifting bar handles were created.
However, previous weightlifting bar handles include sliding sleeves that are only compatible with weightlifting bars that use removable weight plates, not barbells or dumbbells, for example. These handles are inconvenient, require removal of weights, and are only usable for bars of a certain diameter.
In another example, previous weightlifting bar handles are formed having only one grip area thereby limiting a user to one-handed exercises.
In yet another example, previous weightlifting bar handles often modify or require an inconvenient center of gravity and/or weight distribution. Causing an inappropriate weight distribution and/or inappropriate center of gravity may destroy the intended efficacy of an exercise or even cause injury to a lifter.
Therefore, a need exists to provide a weightlifting bar attachment that can be more easily releasably attached to barbell or dumbbell bars having various diameters and/or that provide an appropriate center of gravity and/or weight distribution for weightlifting.
This summary is provided to introduce a variety of concepts in a simplified form that is disclosed further in the detailed description of the embodiments. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
The embodiments provided herein relate to exercise or fitness equipment. In some examples, exercise or fitness equipment may include weightlifting devices such as dumbbells and barbells. In some embodiments, the present disclosure relates generally to attachments, devices, and/or apparatuses for use in weightlifting.
In some embodiments, systems, devices, and/or apparatuses such as removable attachments, bars, multi-bars, or handles, are disclosed that allow binding to a wide variety of dumbbells and barbells available on the market. Binding to dumbbells and barbells of various sizes, types, brands, shapes, weights, dimensions, diameters and/or handle diameters, etc., is advantageous to allow interoperability and adaptability. In some examples, the variety of exercises that can be performed with a single dumbbell or barbell may be expanded to include two-handed techniques with minimal additional equipment. In some examples, this can reduce costs of additional equipment, storage space needed to store additional equipment, etc.
In some embodiments, removable multi-bar dumbbell attachments are disclosed. In some embodiments, a multi-bar frame, device, and/or attachment comprising one or more bars and/or sets of grip areas is disclosed. In some embodiments, a multi-bar frame, device, and/or attachment comprising two sets of bars comprising grip areas is disclosed, wherein one set of bars is narrow, and one set of bars is wide.
In some embodiments, removable multi-bar dumbbell attachments are disclosed comprising a centered U-channel and clamp lid attached via a hinge and/or pivot point. In one example, a rivet or rivet-like may attach a clamp lid to a housing.
In some embodiments, a U-channel allowing for centered positioning of a dumbbell or barbell is provided. Such embodiments may attach and hold a dumbbell or barbell wherein a center of gravity and/or weight distribution of a dumbbell or barbell may be centered and/or at a midpoint of an axis defined by a lifter's hands when gripping bars on either side.
In some embodiments, a U-channel comprises a notch-and-tooth mechanism on an upper and lower end. In some embodiments, one or both of a U-channel and clamp lid are padded. In some embodiments, use of clamps and notch-and-tooth mechanisms in lieu of screw mechanisms are advantageous in that they are quick and easy to attach to a dumbbell or barbell. For example, such mechanisms do not require a greater force or work to attach, such as the force or work required to attach screw or pull-pin mechanisms.
In some embodiments, a safety strap may be included. In some examples, a nylon and Velcro safety strap may be included that may wrap around a center binding mechanism.

Riveting and/or Riveting Like Techniques
In some embodiments, a riveting-like technique may be used to attach one or more bars to central housing.
A rivet may be considered a permanent mechanical fastener in some cases. For example, a rivet may comprise of a smooth cylindrical shaft with a head on one end, similar in shape to a screw. The end opposite to the head may be called the tail.
During installation, a rivet may be placed in a punched or drilled hole, and the tail may be upset, or bucked (i.e., deformed), so that it expands to about, for example, 1.5 times the original shaft diameter, holding the rivet in place.
That is, pounding or pulling creates a new “head” on the tail end by upsetting and or deforming the “tail” material flatter, resulting in a rivet that is roughly a dumbbell shape. An original rivet head may be referred to as the factory head and the deformed end may be referred to as the shop head or buck-tail.
By effectively creating a head on each end of an installed rivet, such an installation can support tension loads. However, such an installation is even more capable of supporting shear loads (loads perpendicular to the axis of the shaft).
In some embodiments, a riveting and/or riveting like technique is used to produce an attachment that can advantageously withstand powerful shear loads associated with weightlifting.
For purposes herein, bars installed using a riveting-like technique as just described may be referred to as, for example, “riveted”, “riveted bars”, and/or “riveted handles.” Further, purposes herein, bars or handles installed using a riveting-like technique through one or more end plates may be described as bars or handles that are “riveted to”, “riveted through”, or “riveted within” the one or more end plates, for example.
In one example, first bar 301 may be comprised of a factory head and tail used as a shop head, as described. First bar 301 may be passed through a hole 309a and fixed or installed to end plate 303a using a riveting and/or riveting-like technique. Alternatively, and/or in combination, a welding technique may be used to fix and/or install first bar 301 within or to end plate 303a.
In another example, second bar 302 may be comprised of a factory head and tail used as a shop head, as described. Second bar 302 may be passed through a hole 309b and fixed or installed to end plate 303a using a riveting and/or riveting-like technique. Alternatively, and/or in combination, a welding technique may be used to fix and/or install second bar 302 within or to end plate 303a.
It will be understood that first bar 301 and second bar 302, for example, may be similarly fixed and/or attached to second end plate 303b.
Similarly, support or support member 303c may be riveted through one or more end plates such as end plate 303a.
In some embodiments, central housing 303 may further comprise one or more safety mechanisms, such as a safety strap 308. Safety strap 308 may comprise a nylon and/or Velcro safety strap that can wrap around the center binding mechanism and/or clamp lid 305a when in a closed position, as shown in 300, for example.
