In general, the embodiments described 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.

Embodiments herein may be compatible with some or all aspects or parts of disclosures such as in “Weightlifting Bar Handle,” US 2022/0062693 A1, which is incorporated by reference in entirety herein.

However, this prior art disclosure fails, for example, to provide/maintain a center of gravity and/or weight distribution wherein the center of gravity of the weight being lifted is between the lifter's hands (between the grips) such as at a center or midpoint on an axis defined by the lifter's hands. Instead, the center of gravity is removed/displaced from the center of this example axis. Further, this prior art disclosures requires set screws and the like, which is further inconvenient, cumbersome, and even dangerous.

Embodiments herein may be compatible with some or all aspects or parts of disclosures such as in “An apparatus for reducing body stress on an exerciser,” US 2006/0105890 A1, which is incorporated by reference in entirety herein. For example, examples of a “W” configuration bar are described and compatible with embodiments described herein.

Embodiments herein may be compatible with some or all aspects or parts of disclosures such as in “multi-grip exercise bar,” U.S. Pat. No. 9,254,410 B1, which is incorporated by reference in entirety herein. For example, examples of a curl bar are described and compatible with embodiments described herein.

In some embodiments, systems or devices, such as removable attachments, bars, multi-bars, multi-grip bars, or handles, are disclosed that allow binding to a wide variety of dumbbells, barbells, and exercise equipment 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.

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 bar301may be comprised of a factory head and tail used as a shop head, as described. First bar301may be passed through a hole309aand fixed or installed to end plate303ausing a riveting and/or riveting-like technique. Alternatively, and/or in combination, a welding technique may be used to fix and/or install first bar301within or to end plate303a.

In another example, second bar302may be comprised of a factory head and tail used as a shop head, as described. Second bar302may be passed through a hole309band fixed or installed to end plate303ausing a riveting and/or riveting-like technique. Alternatively, and/or in combination, a welding technique may be used to fix and/or install second bar302within or to end plate303a.

It will be understood that first bar301and second bar302, for example, may be similarly fixed and/or attached to second end plate303b.

Similarly, support or support member303cmay be riveted through one or more end plates such as end plate303a.

In some embodiments, central housing303may further comprise one or more safety mechanisms, such as a safety strap308. Safety strap308may comprise a nylon and/or Velcro safety strap that can wrap around the center binding mechanism and/or clamp lid305awhen in a closed position, as shown in300, for example.

Releasable locking mechanisms509aand509bmay, for example, engage with notch and tooth mechanisms on upper507b, lower507c, respectively, to clamp lid507ain a closed position around, for example, a handle and/or grip of a dumbbell or barbell.

In some embodiments, housing and/or central housing505may comprise one or more end plates505a-505b. In some embodiments, end plates505a-505bmay be rectangular and/or comprise rounded sides and/or ends. Rounded sides may allow for safety advantages in some cases.

In some embodiments, one or more bars may be installed and/or attached to housing or central housing wherein the one or more bars are installed symmetrically to each other. In one example, first bar501may be installed and/or attached to central housing end plates505a-505bsymmetrically to second bar502.

In some embodiments, each of end plates505a-505bmay comprise a shape and/or cutout comprising a U-shaped channel (“U-channel”) allowing intake of a dumbbell or barbell (such as a dumbbell handle).

Rounded end plates may be attached to, or by, one or more bars. For example, as shown in500, first bar501and second bar502may each be attached to each end plate, creating a contiguous and/or reinforced structure.

In some embodiments, end plates may comprise holes through which one or more bars are fitted. In some examples, bars may be set within holes and protrude from holes by, for example, between 0.15 inches and 0.5 inches on each side of end plate attachment. Each protrusion may allow for welding, riveting and/or fixing bars within their respective holes to provide a structurally sound device, such as by a welding technique, riveting technique, or riveting-like technique, as described previously.

In one example, end plates505a-505bmay comprise holes or openings through which first bar501and second bar502are fitted. For example, first bar501may be fitted through first hole511a. And, for example, second bar502may be fitted through second hole511b.

As described previously, a riveting technique, or riveting-like technique may be used to install and/or attached one or more bars to end plates.

In one example, first bar501may be comprised of a factory head and tail used as a shop head, as described. First bar501may be passed through a hole511aand fixed or installed to end plate505ausing a riveting and/or riveting-like technique. Alternatively, and/or in combination, a welding technique may be used to fix and/or install first bar501within or to end plate505a.
