DETAILED DESCRIPTION

In this description, references to “one embodiment,” “an embodiment,” or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment,” “an embodiment,” or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the technology can include a variety of combinations and/or integrations of the embodiments described herein.

Exercise equipment is well known in the art and varies from complex machinery to simple devices, wherein a user may select various equipment based on their needs. Many exercise equipment utilize a cable system to create resistance such that as a user engages with a user engageable device, the cable provides resistance thereto, such as through connection to one or more weights or weight supporting devices. Many exercise equipment also utilize one or more vertical posts for supporting user engageable devices. For example, gyms (both commercial and home) generally use a frame with one or more vertical posts for supporting barbells or other equipment. In other words, it is common for gyms to already have a frame structure with vertical uprights available. Conventional cable machines are traditionally large, standalone units, taking up large footprints in a gym or office, and accordingly are not always suitable for small spaces and further not worth the footprint.

The present invention provides for a rack pulley system in which an upper pulley system and a lower pulley system are attached to a vertical post and support a cable extending therebetween. The upper and lower pulley systems are easily attached to the vertical post such that any conventional upright/frame system can support the pulley system. The present invention further utilizes a trolley, positioned along the vertical post at a position between the upper pulley system and the lower pulley system, the trolley supporting weight sleeve such that a user can add weight to the trolley. The trolley specifically is easy to couple to the cable, such that the trolley can be used with or without the cable. Again, the trolley here can be easily added to the vertical post such that no special upright system is needed, rather the user can easily add the system of the present application to conventional equipment. The upper pulley system and lower pulley system are each configured to receive one or more attachments such that high and low cable functions can be performed. For example, a user may add a handle attachment to the top or bottom and complete an exercise therewith. Accordingly, with minimal additions, a user can add an entire cable system, with a plurality of configurations, to a conventional upright/frame/vertical post. If the user decides to remove the system, the system can be easily stored.

The trolley of the present invention includes a trolley cable guide which is configured to connect the trolley to the cable such that the trolley can operate with the cable or without the cable. In other words, the user can attach the cable, add weight, and then use a device at the top or bottom end of the cable to complete an exercise, or, as desired, the user can disconnect the cable and add a user engageable device directly to the trolley (such as a handle) and use the trolley alone. Again, the attachment to the cable itself is seamless such that the trolley is easily connected thereto. This allows for a user to customize their use of the equipment. In the preferred embodiment, the upper pulley system, lower pulley system, and trolley are all mounted to a single vertical post.

As shown best in FIG. 1, the rack pulley system 100 includes the upper pulley system 102 engaged with the vertical post 104, a lower pulley system 112 engaged with the vertical post 104, and a trolley 108 engaged with the vertical post 104 at a position between the upper and lower pulley systems 102, 112. The upper pulley system 102 is mounted near a top end, while the lower pulley system 112 is mounted to a lower end, however, the exact locations of connection can vary. For example, although the upper pulley system 102 is shown mounted to the top two holes of the vertical post 104, and the lower pulley system 112 is shown mounted to the two bottom holes, slight changes are contemplated for positioning.

Those skilled in the art will appreciate that the trolley 108 may vary, but in most embodiments includes weight sleeve 111. The weight sleeve 111 allows for the user to add weighted resistance to the system. The trolley 108 also specifically includes one or more rollers that allow for the trolley to easily glide up and down the vertical post 104. The trolley can also include an attachment mechanism such that a user can attach handles, pads, or other components to the trolley.

Trolley 108 further includes a trolley cable guide 110 configured to connect the trolley 108 to a cable 106 and therefore couple the trolley 108 to the upper and lower pulley systems 102, 112. As shown best in FIG. 4, the cable 106 extends between all three. The trolley cable guide 110 allows for the cable 106 to be disconnected from the trolley 108 easily. For example, the user can merely retain the cable 106 in a position (simply hold with their hand), lift up on the weight sleeve 111 to allow the cable 106 to slack from the cable guide 110, and then disengage the two fully. In some embodiments, the trolley cable guide 110 is threaded such that it can loosen and tighten, thereby again allowing for easy engagement with the cable 106.

As best shown in FIG. 2, the upper pulley system 102 includes a housing 208 mounted to a bracket 206 which is further configured to mount to the vertical post 104. In embodiments, one or more pins 204 are used to create a secure mount, however, alternative means of mounting may be used. The one or more pins 204, in embodiments, are designed with a threaded end and flanged head such that they attach through the vertical post 104 and can be engaged and disengaged without any specialized tools. In other words, the use of pins, threaded or not, allows for easy mounting to the vertical post 104. This allows for the upper pulley system 102 and the lower pulley system 112 to be easily removed from the vertical post 104 such as for storage. The housing 208 supports a plurality of cable guides 200a-d, which allow for the cable 106 to extend therethrough to an upper end 202, where an attachment may be added as desired. Specifically, the cable 106 will travel between a top guide 200a and a bottom guide 200d and then in a downward direction (i.e. toward the trolley 108). The cable 106 then bends around back in an upward direction at the trolley 108 where it will re-enter the housing 208 and circle around a lower rear cable guide 200c and below an upper rear cable guide 200b. From there, as shown in FIG. 4, the cable 104 travels downward to the lower pulley system 112.

As shown in FIG. 3, lower pulley system 112 is similar to the upper pulley system 102 and includes a housing 308 mounted to a bracket 306 which is further configured to mount to the vertical post 104 such as through use of one or more pins 302. Again, the one or more pins 302 are configured for easy removal of the lower pulley system 112. The housing 308 supports a plurality of cable guides 300a-d such that the cable 106 extends therethrough to a lower end 304 to allow for attachments. Here, starting at the lower end 304, the cable travels between a top guide 300a and a bottom guide 300d, but instead of curving, the cable 106 continues rearward in between guides 300b and 300c before curving upward.

The primary components, namely the upper and lower pulley systems, 102, 112 and the trolley 108, independently attach to/detach from most square post rack setups via rack pins, which offers a tool-free, compact and minimal solution to integrate and/or retrofit a dual point, single cable high/low pulley system to most squat rack setups. Furthermore, the system 100 attaches to a rack-mounted trolley 106 to provide necessary weight resistance, allowing the trolley to be used independent from the system and expanding the range of exercises capable within a small footprint.

Turning to FIG. 4, the path of the cable 106 is specifically shown, wherein the cable starts at upper pulley system 102, loops down to the trolley 108, loops back up to the upper pulley system 102 again, and then back down to the lower pulley system 112.

During operation, a user can add an attachment to the top end of the cable 106 and pull down, wherein the trolley 108 will then travel upward with resistance. Alternatively, the user can add an attachment to the bottom end of the cable 106 and pull upward, wherein again, the exerted force will cause the trolley 108 to travel upward with weighted resistance.

Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present disclosure. Embodiments of the present disclosure have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present disclosure. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. Not all steps listed in the various figures need be carried out in the specific order described.
