Dumbbell attachment apparatus with two-handed grip configuration
View Patent ↗In some embodiments, systems or devices, 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.

5. The device of claim 4 , wherein the first grip area and the second grip area are configured to allow a user to simultaneously take a first grip of both the first grip area and the second grip area to manipulate a first attached dumbbell or barbell.
6. The device of claim 5 , wherein the third grip area and the fourth grip area are configured to allow a user to simultaneously take a second grip of both the third grip area and the fourth grip area to manipulate the first attached dumbbell or barbell.
7. A dumbbell or barbell attachment device to enable two-handed exercises, comprising:
a first bar comprising a first grip area, wherein the first bar is comprised of cast iron, steel, aluminum, brass, ceramic, carbon fiber, or plastic;
a second bar comprising a second grip area, wherein the second bar is comprised of cast iron, steel, aluminum, brass, ceramic, carbon fiber, or plastic, wherein the first bar and the second bar are each riveted to a central housing comprising a first end plate and second end plate, and wherein the central housing is comprised of cast iron, steel, aluminum, brass, ceramic, carbon fiber, or plastic;
wherein the first bar and the second bar are of equal size and equal shape, wherein the first bar and the second bar are cylindrical, and wherein the first bar and second bar are arranged in a configuration parallel to each other;
wherein the third bar and the fourth bar are each in a curl bar shape or configuration; and
wherein the central housing comprises: a first U-channel, the first U-Channel comprising a first support member sized and shaped to accommodate a weightlifting bar having a first diameter within a first range of diameters; and a first clamp lid comprising an upper notch and tooth mechanism and a lower notch and tooth mechanism.
8. The device of claim 7 , wherein the central housing further comprises:
a first releasable locking mechanism to engage the upper notch and tooth mechanism, wherein the first releasable locking mechanism comprises a first locking attachment to the central housing rotatable about a first screw or pivot element, and wherein the first locking attachment comprises a first lever, clip, handle, or switch.
9. The device of claim 8 , wherein the central housing further comprises:
a second releasable locking mechanism to engage the lower notch and tooth mechanism, wherein the second releasable locking mechanism comprises a second locking attachment to the central housing, rotatable about a second screw or pivot element, and wherein the second locking attachment comprises a second lever, clip, handle, or switch.
10. The device of claim 9 , wherein one or more sides or edges of the first U-channel are padded.
11. The device of claim 10 , wherein the dumbbell or barbell attachment device can be releasably attached to weightlifting bars of varying diameters.
12. A dumbbell or barbell attachment device to enable two-handed exercises, comprising:
a first bar comprising a first grip area;
a second bar comprising a second grip area, wherein the first bar and the second bar are each riveted to a first end plate and a second end plate, wherein the first grip area and the second grip area allow a user to simultaneously take a first grip of both the first grip area and the second grip area to manipulate a first attached dumbbell or barbell, and wherein a center of gravity of the first attached dumbbell or barbell is at a midpoint defined by an axis;
