The disclosed subject matter relates generally to exercise equipment, and in some embodiments, for example, to cable attachment systems and methods for exercise equipment.
Gyms often have cable stations with attachment points for connecting a carabiner or threaded link to various exercise attachments. The cables on these stations are prone to wear and tear and breakage, particularly when exercisers operate the machines outside of the machine's designed use. It is common, for example, for an exerciser to grab a cable by the fittings and do triceps extensions, which bends the cable repeatedly, fatiguing the steel fibers and leading to breaking cables. This can lead to injury or poorly performing or broken machines.
Cable-based systems are also commonly used for strength training and suspension training routines in which the users quickly switch between pushing and pulling exercises. When switching in this manner, standard round grips can be uncomfortable and may concentrate the load on the user's palm during pushing exercises. Some conventional systems include multiple sets of grips or grips with a wider center. However, these solutions can be costly or require equipment modification.
In view of the foregoing, it is desirable to provide new exercise systems and methods for cable attachments that address one or more of the drawbacks of conventional systems.
The present disclosure is directed to various improved cable attachment systems and methods for exercise equipment. In some embodiments, a multi-profile grip is disclosed that allows for comfortable use during both pulling and pushing exercises.
In some embodiments, a cable molded grip and/or fabric strap are disclosed that may be used as cable attachments for adjustable-height cable stations, such as a multi-station selectorized weight machine, and other cable equipment.
The scope of the present disclosure is defined by the claims, which are incorporated into this section by reference. A more complete understanding of the present disclosure will be afforded to those skilled in the art, as well as a realization of additional advantages thereof, by a consideration of the following detailed description of one or more embodiments. Reference will be made to the appended sheets of drawings that will first be described briefly.
Various objects, features, and advantages of the disclosed subject matter can be more fully appreciated with reference to the following detailed description of the disclosed subject matter when considered in connection with the following drawings, in which like reference numerals identify like elements.
The present disclosure describes various improved cable attachment systems and methods for use with exercise equipment.
In some embodiments, cable attachments are designed for use on an adjustable-height cable station, such as in a gym's multi-station selectorized weight equipment area. The ends of the cables on these machines often have some an attachment point for attaching a carabiner or threaded link, and then attaching other attachments to the carabiner or link For adjustable-height cable stations, there is typically a device to prevent the cable end parts from getting pulled back into the pulleys while adjusting the height of the pulley carriage.
Referring to
There is typically a device to prevent the cable end parts from getting pulled back into the pulley while adjusting the height of the pulley carriage 110. As illustrated in
These devices at the end of the cables also facilitate use of the cable without attachments, which can lead to problems as discussed herein. Referring to
The present disclosure solves the above-mentioned problem by providing a unique cable molded grip and pliable strap.
The molded grip may be implemented in a variety of ergonomic shapes, including a large ball 320D or a small ball 320C (see also
The pliable strap can bend in any direction without fatiguing and eventually breaking, unlike the steel cable. Additionally, the pliable strap is soft, which reduces the chances of a user getting their hand pinched by it. In various embodiments, the molded grip 320A-D may be made of rubber, plastic, or other suitable robust but lightweight material(s), such as lighter die-cast metals such as aluminum. In various embodiments, the pliable strap may be made of a rugged fabric or similar material providing the pliability described herein.
In some embodiments, the molded grip 320A-D has one or two holes formed therethrough. Having two holes allows an arrangement in which the molded grip 320A-D is trapped on the strap 330A-D. In some embodiments, a fabric sleeve could be provided to cover the straps 330A-D from the end of the molded grip 320A-D to a U-bracket 350, to keep the straps together and present a mono-body look. The molded grip and pliable strap described herein can be attached to any adjustable pulley cable station. When not being used for single arm triceps extensions, users can attach the other standard attachments to the carabiner for using the station in typical fashion.
The embodiments described herein solve the problem of cables breaking from exercisers using them improperly. The cable molded grip and fabric strap provide an intentional grab-point for exercisers to do triceps extensions and other exercises preventing the exercisers from grabbing the cable by the fittings and bending the cable repeatedly. Use of the cable molded grip and fabric strap may lead to more equipment uptime and less risk of injury.
In some embodiments, a single rope attachment and/or a short length of rope or chain could possibly be used instead of the strap, with or without the molded shape depending on the thickness (see, e.g.,
An example method 700 for using an implementation of a molded grip and pliable strap of the present disclosure will now be described with reference to
In block 704, the fabric strap is looped through the hole(s) in the molded grip. In block 706, a first end of the fabric strap is attached to the end of a cable on a machine (e.g., via a U-bracket). In block 708, the loop at the second end of the fabric strap is attached to a cable attachment (e.g., rope attachment, straight bar attachment, etc.) for exercise using the cable attachment. In block 710, the cable attachment is detached from the fabric strap allowing the fabric strap and molder grip to be used for triceps extensions (or another exercise as appropriate).
Exercise equipment such as TRX straps and various cable-based machines are commonly used for strength training and suspension training During exercise, users often switch between pushing and pulling exercises, but standard round grips can be uncomfortable and may concentrate the load on the user's palm during pushing exercises. Some conventional approaches include multiple sets of grips or grips having a wider center. However, these solutions can be costly or require equipment modification.
The present disclosure provides a multi-profile grip that addresses the problem of uncomfortable grip during pushing exercises. The multi-profile grip may be implemented as a cable attachment which may be attached to a carabiner at the end of a cable, such as a carabiner attached to a molded grip and fabric strap as disclosed with reference to
Referring to
The grip may be made of any suitable material, such as rubber or foam. The grip may be secured to the exercise equipment using any suitable means, such as a screw or clamp. In some embodiments, the grip may be implemented as a cable attachment for use with a cable machine. The multi-profile grip may be used with a variety of exercise equipment, including suspension training equipment like TRX, strength training equipment like Cobra, and cable-based strength equipment.

Example cable fittings that may be disposed between a cable and a carabiner/attachment will now be described with reference to
As previously discussed, users of pulley stations on selectorized equipment (or other exercise equipment that includes a resistance cable/band/pulley or similar arrangement) often grab the cable by whatever is on the end of the cable (typically a ball or other easy-to-grab shaped object) and do triceps extensions or similar exercises. This causes the cable to bend over the edge of the ball or fitting at the end of the cable (see, e.g.,
One approach addresses this wear-and-tear (i.e., cable wear at that edge of the fitting), by replacing the fitting with a disk and barrel yoke that less adaptable to grabbing by a user. However, users continue to look for ways to grab the cable fitting and this barrel-yoke approach may actually result in cables wearing faster than the previous ball-style fittings. In a test environment, for example, a simulated triceps extension movement performed with a ball-style fitting resulted in cable wear in the 4000-8000 cycle range, while the barrel-yoke fitting resulted in cable wear in as little as 200 cycles.

The housing 1110 is adapted to receive the cable 1130 through the top opening 1112. An anchor point cable termination, ball shank 1132 (e.g., a metal ball shank) in the illustrated embodiment, is attached at the end of the cable 1130 and adapted to be fed through the top opening 1112 and secured to the housing 1110. In some embodiments, the ball shank 1132 terminates the cable 1130 and includes a spherical, ball-shaped, or similar component at the end of the cable 1130 adapted to fit into a corresponding slot, socket or other receptacle, allowing for a secure and reliable connection between the cable 1130 and the housing 1110. The ball shape provides flexibility and enables multidirectional movement, making it suitable for movements that include articulation or rotation as described herein.
A bracket 1150 may be inserted into the bottom opening 1114 and includes a slot 1152 that is wider than the diameter of the cable 1130 and narrower than the ball shank 1132. The bracket 1150 includes an opening 1153 adjoining the slot 1152 and adapted to receive the ball shank 1132 allowing the cable 1130 to pass through the slot 1152 and out the top, where the ball shank 1132 is secured against a lip 1155 of the bracket 1152.
To attach the fitting 1100, the ball shank 1132 at the end of the cable 1130 is fed through the top opening 1112 of the housing 1110 and into the hole 1153 of the bracket 1150. The bracket 1150 is rotated along the slot 1152, allowing the cable 1130 to pass through the slot 1152 to a position in which the bracket 1150 is supported by the ball shank 1132. Next, the housing 1110 is lowered over the bracket 1150, which may be supported by an interior surface of the housing 1110. In the illustrated embodiment, the housing 1110 is shaped to facilitate gripping by a user's hand during exercise, and includes an interior surface portion 1118 that includes an opening narrower than the diameter of the bracket 1150, allowing the bracket 1150 to be supported within the housing 1150 during operation. In some embodiments, the interior surface portion 1118 may include a lip or other structure to block the bracket 1150 from passing through the housing 1110.
The holes 1154 and 1156 of the bracket 1150 have corresponding holes 1116 on the housing 1110, which align to enable a bolt 1140 to pass through where it can be secured by a nut 1142. A carabiner 1120 fits around the bolt 1140 to enable handle attachments to be used with the fitting 1100. In some embodiments, the carabiner 1120 may be positioned in the housing 1110 before the bolt 1140 is pushed through and attached to the housing 1110.
The installed fitting 1100 allows a user to perform exercises (e.g., triceps extensions) using the fitting 1100 as a grip/handle while mitigating wear and tear on the cable 1130. As illustrated, the radiused surface 1008 provides a smooth surface where the cable 1130 may contact during use. When viewed from above, the radiused surface 1008 has a round shape (e.g., circular or other rounded shape).The radiused surface 1008 has curved contour angles that transition smoothly from the interior of the housing 1100 adjacent to the bracket 1150 to the upper rim of the radiused surface 1008, providing a continuous and seamless surface without sharp edges or corners to unduly bend and/or crimp the cable 1130. In some embodiments, the diameter of the radiused surface varies throughout the height, increasing towards the rim, and the contour angles change gradually to avoid abrupt changes or irregularities in areas where the cable 1130 may contact during exercise.
