Rope mechanism attachment device for exercise equipment

Abstract

The rope mechanism for exercise equipment eliminates rope fraying by using two separate rope segments instead of a single continuous rope. A first rope segment is affixed to a first bracket and a second rope segment is affixed to a second bracket. The brackets are pivotably connected and configured to pivot relative to each other. Because each rope segment is fixed to its respective bracket, nylon-to-metal friction is eliminated. Instead, the brackets pivot relative to each other, creating metal-to-metal friction that does not damage the rope. Each rope segment is individually supported at one end, eliminating concentrated stress at a center point. Limit stops control the range of pivoting motion. A swivel mechanism allows the assembly to rotate 360 degrees. An eyebolt allows attachment to cable-operated exercise equipment.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to U.S. Pat. App. Ser. No 63 / 777,675, filed Mar. 25, 2025, titled CABLE ROPE ATTACHMENT FOR EXERCISE EQUIPMENT.FIELD

[0002] This invention relates to the field of exercise equipment and more particularly to cable rope attachments for exercise equipment.BACKGROUND

[0003] Cable rope attachments are used in gyms in combination with cable-operated exercise equipment to perform resistance exercises. The attachments connect to cable pulleys or weight stacks and provide a gripping surface that allows users to perform a wide range of exercises targeting the upper body, lower body, and core muscle groups.

[0004] Traditional cable rope attachments include a single continuous rope inserted through a tubular steel support bracket. The tubular support bracket attaches to a cable pulley or other gym equipment. The rope is typically made from nylon material and has rubber grips attached at each end to prevent the user’s hand from sliding off the rope.

[0005] But during use, the rope of traditional attachments rubs against the steel bracket, causing the rope to fray. The fraying deteriorates the rope and forces gyms to replace cable rope attachments multiple times per year.

[0006] Additionally, the single continuous rope of a traditional attachment concentrates the weight and friction at the center point where the rope passes through the support bracket. This concentrated stress creates a failure point that leads to rope breaking over time, exacerbated by the fraying of the rope.

[0007] Frayed and worn-out cable rope attachments generate frequent complaints from gym members. The unsightly condition of frayed ropes creates a negative impression that can damage a gym's brand reputation and member satisfaction. Despite attempts to replace traditional nylon ropes with plastic grips or different rope types, users consistently prefer the classic nylon rope with rubber grips.

[0008] What is needed is a cable rope attachment that eliminates rope fraying by preventing nylon-to-metal friction and that eliminates concentrated stress at a center point of the rope.SUMMARY

[0009] The rope mechanism for exercise equipment provides an improved design that eliminates rope fraying and extends equipment lifespan by using two separate rope segments in place of a single continuous rope. Each rope segment is individually secured and supported at one end within its own bracket, which eliminates both friction between the rope and the bracket and concentrated stress at a center point. The rope mechanism for exercise equipment includes a first rope segment affixed to a first bracket, a second rope segment affixed to a second bracket, and a connecting hook that supports both brackets. A pivot point extends through the first bracket, the second bracket, and the connecting hook, allowing the brackets to pivot relative to each other.

[0010] The first rope segment is affixed to the first bracket and the second rope segment is affixed to the second bracket, which means the rope segments do not move relative to their respective brackets during use. This design eliminates nylon-to-metal friction. Instead, the brackets pivot relative to each other, avoiding any sliding of the rope segments. This fundamental change in how the components interact prevents the rope fraying that plagues traditional rope mechanisms.

[0011] To clarify, the first rope segment and the second rope segment are separate and distinct. They are not two pieces of the same rope, but separate pieces of rope. As a result, there is no shared central rope section that can become frayed due to bending and sliding. Instead, all of the bending and rotational movements and loads are borne by the brackets and pivots of the mechanism.

[0012] Additionally, the brackets optionally include limit stops that prevent over-rotation. In one embodiment, the primary pivot arms of the first bracket include an upper limit stop surface and a lower limit stop that interact with upper limit stop arms and the lower limit stop arms of the second bracket to control the range of pivoting motion. The upper limit stop includes an upper limit stop face that contacts an upper limit stop surface. The lower limit stop includes a lower limit stop face that contacts a lower limit stop surface.

[0013] When the brackets pivot into a brackets-closed position, the lower limit stop face contacts the lower limit stop surface to prevent further downward pivoting. When the brackets pivot into a brackets-open position, the upper limit stop face contacts the upper limit stop surface to prevent further upward pivoting. In some embodiments, the rope separation angle between the two rope segments ranges between 20 degrees in the brackets-closed position and 80 degrees in the brackets-open position when the rope segments extend straight from the brackets.

[0014] In alternative embodiments, the limit stops are configured in different ways to control the range of pivoting motion. In some embodiments, the limit stops are adjustable, allowing a user to modify the rope separation angle range by repositioning the upper limit stop or the lower limit stop along the bracket. In other embodiments, the limit stops include cushioning material such as rubber pads or foam that reduce impact noise when the limit stop face contacts the limit stop surface. In further embodiments, both the first bracket and the second bracket include limit stops that interact with each other to control the range of motion. In some embodiments, the limit stops are spring-loaded or elastic, providing resistance to pivoting while still allowing movement beyond the nominal limit points under sufficient force. In certain embodiments, the brackets include detent positions at specific angles that provide tactile feedback to the user during pivoting. In still other embodiments, the rope mechanism for exercise equipment includes no limit stops, allowing the first bracket and the second bracket to pivot freely through a full range of motion without mechanical restrictions.

[0015] In the primary embodiment, the pivot point between the first bracket and the second bracket comprises a pivot aperture at the end of each arm of the pair of primary pivot arms and a pivot aperture at the end of each arm of the pair of secondary pivot arms, where the pivot apertures align to receive the pivot point therethrough. This dual-arm configuration provides stability and distributes pivoting forces across multiple contact points.

[0016] In alternative embodiments, each bracket includes only a single pivot arm with a single pivot aperture, reducing material usage and simplifying construction. In other embodiments, the pivot apertures are replaced with a hinge mechanism that allows the first bracket and the second bracket to pivot relative to each other.

[0017] The connecting hook includes a passage extending therethrough that receives the pivot point. An annular swivel portion is rotatably attached to the main body and is configured to allow the main body to rotate freely a full 360 degrees in either direction relative to the annular swivel portion. This swivel capability allows the entire rope mechanism for exercise equipment to rotate laterally during use, as indicated by the device rotation angle, accommodating natural rotational movements during exercise and providing users with greater freedom of motion.

[0018] An eyebolt is fastened to the connecting hook and includes a shank having an eyebolt fastener that engages a threaded opening in the annular swivel portion. A ring is attached to the top of the shank and is configured to allow the eyebolt to be removably latched to a cable pulley or other gym equipment. This standard attachment method ensures compatibility with existing gym equipment while maintaining the swivel functionality.

[0019] Each rope segment is preferably secured within its respective bracket via a rope bolt that threads through its respective bracket, and threads into a female mechanical fastener secured to the upper end of each rope.

[0020] In alternative embodiments, a structural adhesive such as a two-part adhesive secures each rope segment to its respective bracket, while in other embodiments the rope segments are secured by crimping.

[0021] The components of the rope mechanism for exercise equipment are manufactured from stainless steel or painted carbon steel, the rope segments are made from nylon material, and the rope caps are made from rubber or similar grip-enhancing materials.

[0022] The rope mechanism for exercise equipment provides several advantages over traditional designs. The elimination of nylon-to-metal friction prevents rope fraying and extends equipment lifespan significantly. The individual support of each rope segment eliminates concentrated stress points that lead to rope breaking. The pivoting brackets and swivel mechanism enable a natural range of motion during exercise, while the controlled rope separation angle ensures safe and effective exercise performance through the upper limit stop and lower limit stop. The durable construction reduces replacement frequency and lowers maintenance costs for gyms. The improved appearance and performance enhance member satisfaction and protect gym brand reputation, addressing one of the most common complaints gym members have about exercise equipment.BRIEF DESCRIPTION OF THE DRAWINGS
