DETAILED DESCRIPTION

The components of the embodiments as generally described and illustrated in the figures herein can be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The phrase “coupled to” is broad enough to refer to any suitable coupling or other form of interaction between two or more entities, including mechanical interaction. Thus, two components may be coupled to each other even though they are not in direct contact with each other. The phrases “attached to” or “attached directly to” refer to interaction between two or more entities which are in direct contact with each other and/or are separated from each other only by a fastener of any suitable variety (e.g., mounting hardware or an adhesive).

References to approximations are made throughout this specification, such as by use of the term “substantially.” For each such reference, it is to be understood that, in some embodiments, the value, feature, or characteristic may be specified without approximation. For example, where qualifiers such as “about” and “substantially” are used, these terms include within their scope the qualified words in the absence of their qualifiers. For example, where the term “substantially perpendicular” is recited with respect to a feature, it is understood that in some embodiments the feature may have a precisely perpendicular configuration.

The term “lateral” refers to a direction spanning across the width of an exercise station, from side to side. The term “longitudinal” refers to a direction spanning forward or backward through the exercise station, as viewed by a user while performing a typical exercise routine on the station, such as pull-ups or dips. The longitudinal direction and the lateral direction are substantially perpendicular to each other, and each is substantially perpendicular to the vertical direction.

Additional terminology used in this disclosure refers to expanded and collapsed configurations of an exercise station. When the exercise station is expanded and ready for use, it is in an “expanded state.” When the exercise station's first and second stands are collapsed to a low vertical profile, but the base remains expanded, the exercise station is in a “vertically collapsed state.” When the exercise station's first and second stands are collapsed to a low vertical profile, and the base is collapsed to a narrow longitudinal profile, the exercise station is in a “fully collapsed state.”

FIG. 1 depicts a perspective view of a collapsible, freestanding exercise station 100 according to one embodiment of the present disclosure. The exercise station 100 has a base 130, a first stand 110, a second stand 120, and a pull-up bar 140. The base 130 is configured to rest on a floor. The first stand 110 is coupled to one side of the base 130, and the second stand 120 is coupled to an opposite side of the base 130. The first stand 110 is coupled to one side of the pull-up bar 140, and the second stand 120 is coupled to an opposite side of the pull-up bar 140. As described further below, the exercise station 100 has expanded and collapsed configurations.

The exercise station 100 is freestanding in that it supports a user performing an exercise routine while the exercise station 100 rests on a floor without engaging any external structure, including a ceiling, a door frame, or a wall. Further, the exercise station 100 does not require mounting or fixture to the floor. In some embodiments, the exercise station 100 may support a user having a weight of up to three hundred pounds. In some embodiments, the exercise station 100 may support a user having a weight of more than three hundred pounds. For example, the exercise station 100 may sustain a pull-up load of up to one thousand pounds.

The exercise station 100 is collapsible in that it may be collapsed to a low vertical profile and a small base footprint for convenient storage and/or transport. Collapse of the exercise station 100 can be done quickly and simply, without lifting the base 130 off of the floor and without detaching or disassembling any of the components of the exercise station 100. The exercise station 100 remains a single assembly throughout collapse, without any components being removed. In some embodiments, the exercise station 100 may require removal of additional handles (described below in connection with FIGS. 7 and 8), but otherwise is collapsible without disassembly of the other components.

As shown in FIG. 1, the exercise station 100 includes a base 130, a first stand 110, a second stand 120, and a pull-up bar 140. In some embodiments, the exercise station 100 may also include additional handles (see FIGS. 7 and 8). The first stand 110 is positioned on one side of the exercise station 100, and is coupled to the base 130 at a lower end of the first stand 110, and to the pull-up bar 140 at an upper end of the first stand 110. The second stand 120 is positioned on the opposite side (in the lateral direction) from the first stand 110, and is similarly coupled to the base 130 at a lower end of the second stand 120 and to the pull-up bar 140 at an upper end of the second stand 120.

The first stand 110 and the second stand 120, while not necessarily mirror images of each other, each comprise similar components with similar functions. The first stand 110 includes a first lower stand member 112 and a first upper stand member 114. The second stand 120 includes a second lower stand member 122 and a second upper stand member 124. The first and second lower stand members 112, 122 and the first and second upper stand members 114, 124 may be elongate elements such as bars, tubes, angles, channels, rods, or the like. The elongate elements may be elongate structural members formed of a steel alloy or other appropriately strong and rigid material. The first and second lower stand members 112, 122 are each hingedly coupled to the base 130 at respective sides of the base 130 by respective first and second lower hinges 111, 121. Next, the first and second lower stand members 112, 122 are each hingedly coupled to their corresponding respective first and second upper stand members 114, 124 by respective first and second middle hinges 113, 123. Further, the first and second upper stand members 114, 124 are each hingedly coupled to the pull-up bar 140 adjacent respective ends of the pull-up bar 140 by respective first and second upper hinges 115, 125.

The first and second middle hinges 113, 123 may be located in respective middle portions of the first and second stands 110, 120. A middle portion of a stand is a portion between two or more stand members of the stand. Thus, a middle portion of the first stand 110 may be found between the first lower stand member 112 and the first upper stand member 114. The middle portion of a stand need not be precisely at a center of the stand. Thus, a lower stand member and an upper stand member need not have identical lengths.

Also depicted in FIG. 1 are the components of the base 130. The base 130 may comprise a base bar 136 which spans the width of the exercise station 100 (in the lateral direction) and rests horizontally on the floor. The base bar 136 may be an elongate element such as a bar, tube, angle, channel, rod, or the like. In some embodiments, the base bar 136 may be a flat elongate plate that rests flat on the floor, as shown in FIG. 1. The lower hinges 111, 121 may be attached to the base bar 136 on either end of the base bar 136 (and thus on either lateral side of the exercise station 100). The base 130 may further comprise one or more feet 132 that rest horizontally on the floor, and that extend in a longitudinal direction (perpendicular to the base bar 136) when expanded. The feet 132 may be elongate elements such as bars, tubes, angles, channels, rods, or the like. In the depicted embodiment, there are four feet 132: a pair of feet on each lateral side of the exercise station 100, with the feet 132 in each pair of feet extending in opposite longitudinal directions when expanded. Each foot 132 may be coupled to the base bar 136 by a hinge. The hinges that couple the feet 132 to the base bar 136 may or may not comprise a locking mechanism. In some other embodiments, there may be only two feet, with one on either lateral side of the exercise station 100, wherein the feet may span longitudinally in both longitudinal directions from the base 130. In some embodiments there may be a single foot member hingedly coupled to the base bar 136 in the center of the base bar 136, and extendable from the base bar 136 in both longitudinal directions when in an expanded state.

FIG. 2 depicts a front view of the collapsible, freestanding exercise station 100, and provides additional detail, including locking mechanisms for the hinges. The first and second lower hinges 111, 121 each have corresponding first and second lower locking mechanisms 111a, 121a that, when engaged, secure the first and second lower stand members 112, 122 in substantially vertical orientations. The first and second middle hinges 113, 123 each have corresponding first and second middle locking mechanisms 113a, 123a that, when engaged, secure the respective first and second upper stand members 114, 124 to be aligned in substantially colinear orientations with their respective first and second lower stand members 112, 122, thus securing the first and second upper stand members 114, 124 in substantially vertical orientations. The first and second upper hinges 115, 125 each have corresponding first and second upper locking mechanisms 115a, 125a that, when engaged, secure the pull-up bar 140 in a substantially perpendicular orientation with respect to the respective first and second upper stand members 114, 124, such that the pull-up bar 140 is oriented substantially horizontal in the lateral direction. Thus, in the expanded state of the exercise station 100, the pull-up bar 140 has a substantially lateral orientation.

When the several locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a are engaged in a locked state, the exercise station 100 is substantially rigid. The locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a can comprise any of a quick-release pin, a locking quick-release pin, a cotter pin, or a clevis pin on one member, and a receptacle for the pin on the other member (with the terms “member” referring to the respective components that are coupled to each other by the respective hinges). The locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a can comprise any of clamps, latch-style toggle clamps, draw latches, and the like. Alternatively, the locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a can comprise other devices that are engageable to secure the lower and upper stand members 112, 114, 122, 124 in fixed vertical orientations and the pull-up bar 140 in a fixed lateral orientation while the exercise station 100 is in the expanded state.

The locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a each can be easily disengaged into an unlocked state to prepare the exercise station 100 for collapse. Thus, disengagement of the locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a allows the exercise station 100 to fold into a collapsed state. Once the locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a are disengaged, the lower and upper stand members 112, 114, 122, 124 can be rotated inwards (or, in some embodiments, outwards) to fold the exercise station 100 into a vertically collapsed state.

As noted above, FIGS. 1 and 2 depict the exercise station 100 in the expanded state. While in the expanded state, the first and second stands 110, 120 of the exercise station 100 are oriented in a substantially vertical orientation. In some embodiments, the members of the first and second stands 110, 120 may be the only vertically oriented members of the exercise station 100 (while in the expanded state). The pull-up bar 140 is oriented in a substantially horizontal orientation, and more specifically, in a lateral orientation. Aside from tolerancing and other mechanical phenomena that might prevent the pull-up bar 140 from having a precisely horizontal orientation, the pull-up bar 140 may be an elongate element that is not linear across its length. For example, as shown in FIG. 2, the pull-up bar 140 may have bends along its length to facilitate different gripping portions. Nevertheless, the pull-up bar 140 is, on the whole, oriented substantially horizontally and substantially laterally when the exercise station 100 is in the expanded state. In some embodiments, the exercise station 100 may have an expanded-state height he between six feet and eight feet, including approximately seven feet.

In some embodiments, the first and second stands 110, 120 may be coupled to the base 130 through only the lower hinges 111, 121 and their corresponding lower locking mechanisms 111a, 121a, without an additional brace, structural bracket, or other diagonal support member coupling the lower stand members 112, 122 to the base 130. The attachment of the lower hinges 111, 121 to the base 130 may include a brace, structural bracket, or diagonal support member, but that alone may provide enough stability to the exercise station 100 without the need for additional structural elements coupling the lower stand members 112, 122 to the base 130.

In some embodiments, the pull-up bar 140 and the base bar 136 may be the only members that span the lateral width of the exercise station 100 (when in the expanded state). The exercise station 100 may be rigid and stable enough without the need for additional crosswise members.

FIG. 3 depicts a front view of the exercise station 100 during collapse (or, alternatively, during expansion) of the first and second stands 110, 120. In other words, FIG. 3 shows a transition from the expanded state to the collapsed state (or vice versa). Following disengagement of the several locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a, a user may fold the exercise station 100 into the vertically collapsed state by rotating the upper stand members 114, 124 and the lower stand members 112, 122 inwards. The user may exert lateral inward forces on each of the upper stand members 114, 124. These inward forces may cause the middle hinges 113, 123 to move towards each other. To avoid collision or interference between the first and second stands 110, 120 during collapse, the exercise station 100 may be constructed with the first stand 110 offset somewhat in a longitudinal direction from the base bar 136, while the second stand 120 is offset somewhat from the base bar 136 in the opposite longitudinal direction. This longitudinal offset provides room for both the first and second stands 110, 120 to fold into the vertically collapsed state. Additionally, this offset may simplify the construction of the pull-up bar 140 with the upper hinges 115, 125 by providing a coupling spot adjacent each lateral end of, and on opposite longitudinal sides of, the pull-up bar 140 for the respective upper stand members 114, 124. As shown in FIG. 3, the first and second stands 110, 120 are longitudinally offset from each other (in the depicted view, for example, the upper stand member 124 appears in front of the upper stand member 114), allowing them to collapse without interference. Also as shown in FIG. 3, the pull-up bar 140 remains coupled to the upper stand members 114, 124 of the exercise station 100 during collapse.

The exercise station 100 may be collapsed without swinging or moving any components outside of a space substantially defined by the expanded state of the exercise station 100. In other words, in order to collapse the exercise station 100, the exercise station 100 may not need any more room (volume) than that which it already takes up when expanded. In some embodiments, the exercise station 100 may be collapsed without increasing its vertical or longitudinal profiles during collapse. In some embodiments, the exercise station 100 may be collapsed without increasing its vertical, lateral, or longitudinal profiles during collapse. Furthermore, the upper stand members 114, 124 and the lower stand members 112, 122, which substantially define a vertical-lateral plane when in the expanded state, remain substantially in that vertical-lateral plane throughout collapse.

FIG. 4 depicts a front view of the exercise station 100 with the first and second stands 110, 120 fully collapsed into the vertically collapsed state. The vertically collapsed state has a low vertical profile relative to the expanded state. Upon collapse into the vertically collapsed state, the exercise station 100 may rest in the vertically collapsed state, without further action by the user. Alternatively, the user may proceed to collapse the base 130 such that the exercise station 100 takes the form of the fully collapsed state. In some embodiments, the locking mechanisms on the lower and upper stand members 112, 114, 122, 124 may be engageable when in the vertically collapsed state, in which case the user may lock the exercise station 100 in the vertically collapsed state. FIGS. 2 and 4 show that the pull-up bar 140 has a substantially lateral orientation both in the expanded state of the exercise station 100 and in the vertically collapsed state of the exercise station 100.

When the exercise station 100 is in the vertically collapsed state, the first stand 110 and the second stand 120 each are oriented in a substantially lateral orientation. That is, the lower and upper stand members 112, 114, 122, 124 each have a substantially lateral orientation when folded into the vertically collapsed state.

When collapsed, the exercise station 100 may have a height h_C (a vertical profile) that is less than 20% of a height he of the exercise station 100 in the expanded state. For example, some embodiments of the exercise station 100 may have a ratio of vertically-collapsed-state height h_C to expanded-state height he between 10% and 15%, including about 13%. Speaking in terms of absolute length, rather than relative ratios, the vertically-collapsed-state height h_C of some embodiments of the exercise station 100 may be between eight inches and fourteen inches, including approximately ten inches or approximately twelve inches.

FIG. 5 depicts a perspective view of the exercise station 100, in which the first and second stands 110, 120 are collapsed into the vertically collapsed state, and in which the base 130 is being collapsed (or, alternatively, being extended). As explained above, in some embodiments the hinges by which the feet 132 are coupled to the base bar 136 do not have locking mechanisms. For these embodiments, the feet 132 may be rotated inwards (or, in some embodiments, outwards) in the horizontal plane until they are aligned substantially parallel with the base bar 136. In embodiments with locking mechanisms on the hinges coupling the feet 132 to the base bar 136, a user will first disengage the locking mechanisms before rotating the feet 132 into the collapsed state.

A user may exert inward forces on opposite feet 132 on one longitudinal side of the exercise station 100. These inward forces may cause the feet 132 to move towards each other, as shown in FIG. 5. To avoid interference between the feet 132 during collapse, the user may complete folding one foot inward before folding the other foot. In some embodiments, the feet 132 (or one foot 132 of a pair of feet) may be short enough that no such interference would happen.

FIG. 6 shows a perspective view of the exercise station 100, with the base 130 fully collapsed. Thus, in this view, the exercise station 100 is in the fully collapsed state. The fully collapsed state of the exercise station 100 has both a low vertical profile and a small base footprint with a narrow longitudinal profile. The fully collapsed exercise station 100 may have a longitudinal profile with a length dimension that is about the same as the height h_C of the vertical profile of the fully collapsed exercise station 100. For example, the longitudinal width of the fully collapsed exercise station 100 may be between six and eighteen inches, including approximately twelve inches or approximately fifteen inches.

During collapse, the exercise station 100 may remain a single assembly, without any components being removed. The locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a remain coupled to their corresponding hinges 111, 113, 115, 121, 123, 125 while they are disengaged into an unlocked state, and the exercise station 100 may be easily collapsed without disassembly. In embodiments with additional handles (see description of FIGS. 7-8 below), the additional handles may need to be decoupled from the remainder of the exercise station 100 before collapse, but the exercise station 100 otherwise remains assembled during collapse.

To expand the exercise station 100 from a collapsed state, a user may reverse the collapsing process. That is, the user may pull up on the pull-up bar 140 and orient the upper stand members 114, 124 and the lower stand members 112, 122 into their vertical orientations, and then engage the locking mechanisms 111a, 113a, 115a, 121a, 123a, 125a to secure the exercise station 100 in the expanded state.

FIG. 7 depicts a front view of an embodiment of the collapsible, freestanding exercise station 100 with additional handles 151, 152 coupled respectively to the first and second stands 110, 120 of the exercise station 100. The additional handles 151, 152 may support a user performing an exercise routine such as dips or inverted rows. Some embodiments of the exercise station 100, including the embodiment with additional handles 151, 152 depicted in FIG. 7, are laterally wide, with a relatively long pull-up bar 140. The lateral width of a wide embodiment (that is, the length of a long pull-up bar 140) may be between two and a half feet and four and a half feet, including about three feet or about four and a quarter feet. These embodiments may have additional handles 151, 152 that have gripping portions that are offset inwards laterally from their respective stand members. In some embodiments, including the one depicted in FIG. 7, the additional handles 151, 152 are coupled to their respective lower stand members 112, 122. In other embodiments, the additional handles 151, 152 may be coupled to their respective upper stand members 114, 124. The additional handles 151, 152 may be removable from the stand members. Thus, the additional handles 151, 152 may be coupleable to the first and second stands 110, 120, respectively, whereby a user may select whether to use the exercise station 100 with or without the additional handles 151, 152. The additional handles 151, 152 may be foldable on the stand members for easier collapse of the exercise station 100.

Some embodiments of the exercise station 100 are laterally narrow, with a relatively short pull-up bar 140. The lateral width of a narrow embodiment (that is, the length of a short pull-up bar 140) may be between two feet and three and a half feet, including about two and a half feet. These embodiments may have additional handles 151, 152 that are coupled to the first and second stands 110, 120 without any lateral inward offset.

In the view depicted in FIG. 7, the additional handles 151, 152 are coupled to their respective lower stand members 112, 122 at dip bar locations, which are located at a convenient height along the lower stand members 112, 122 for a user to perform dips. The additional handles 151, 152 may have gripping portions with lateral inward offsets from their respective lower stand members 112, 122. The additional handles 151, 152 may be selectively removable from the dip bar locations on the stand members and selectively reinsertable at different locations on the stand members, such as at insertion points 160 along the stands 110, 120. The insertion points 160 may be circular holes, slots, grooves, threaded openings, or the like formed in the stands 110, 120. In some embodiments, the additional handles 151, 152 may need to be removed to collapse the exercise station 100.

FIG. 8 depicts a front view of an embodiment of the collapsible, freestanding exercise station 100 with additional handles 151, 152. The additional handles 151, 152 shown in FIG. 8 can be the same additional handles 151, 152 as shown in FIG. 7, moved to lower locations on the lower stand members 112, 122. The additional handles 151, 152 may support a user while performing an exercise routine such as push-ups. In the view depicted in FIG. 8, the additional handles 151, 152 are coupled to their respective lower stand members 112, 122 at a convenient height for a user to grasp the additional handles 151, 152 and perform push-ups. The additional handles 151, 152 may have a lateral inward offset from their respective lower stand members 112, 122. The additional handles 151, 152 may be selectively removable from the push-up locations on the stand members and selectively reinsertable at different locations on the stand members, such as at insertion points 160 along the stands 110, 120. For example, the additional handles 151, 152 shown in FIG. 8 may be removed from the respective lower stand members 112, 122 and reinserted at higher locations on the stand members—such as at the locations shown in FIG. 7—for use performing dips or inverted rows. The insertion points 160 may be circular holes, slots, grooves, threaded openings, or the like formed in the stands 110, 120. In some embodiments, the additional handles 151, 152 may need to be removed to collapse the exercise station 100.

In some embodiments, there may be several locations along the lower stand members 112, 122 and/or the upper stand members 114, 124 with insertion points 160 in which the additional handles 151, 152 or other equipment are insertable. For example, there may be insertion points 160 in which to selectively insert additional handles 151, 152, or to selectively insert additional support members into the lower or upper stand members 112, 114, 122, 124 for supporting and holding a barbell. The insertion points 160 may be at convenient locations for using the barbell in various exercises, such as a bench press routine, a squat routine, a curl routine, or some other weightlifting exercise. The lower and upper stand members 112, 114, 122, 124 may have numerous such insertion points 160 throughout their lengths for selective insertion of additional support members, such that users of different height may configure the exercise station 100 to suit their personal needs. The insertion points 160 may be circular holes, slots, grooves, threaded openings, or the like formed in the stands 110, 120.

The exercise station 100 in its fully collapsed state may be lifted up off of a floor by a user to engage in other exercise routines, such as curls. For example, a user may curl the fully collapsed exercise station 100 in a manner similar to curling a barbell.

FIGS. 9A and 9B illustrate a resistance band anchor for some of the embodiments of exercise station disclosed herein. In particular, FIG. 9A illustrates progressive movement of a resistance band anchor 202 that is coupled to a base 200 of an exercise station. To illustrate, the resistance band anchor 202 has a contoured hook assembly comprising a hook with three bends and four distinct segments, according to one or more embodiments. The hook is configured to traverse a square tube crossbar (e.g., a base bar of the base 200). A long segment of the hook is of sufficient length to encompass the width of standard-sized resistance bands of varying dimensions.

In some embodiments, the resistance band anchor 202 is coupled to the base 200 through a swivel joint 204. For example, in some embodiments, the hook terminates in a hexagonal nut, which is securely threaded through the crossbar, thereby preventing disengagement. In some implementations, the hexagonal nut is unfastened to the base 200 (while fastened to the anchor 202), allowing the resistance band anchor 202 to pivot freely around its attachment point on the crossbar. In some cases, when a resistance band is not in use with the anchor, the hook rests against the upper surface of the crossbar under the influence of gravity. By lying on the crossbar when not in use, the low profile of the resistance band anchor 202 can reduce exposure as a potential tripping hazard. Moreover, in some embodiments, the resistance band anchor 202 is housed within a free-floating mechanism integrated into the crossbar.

By contrast, as shown in FIG. 9B, manual lifting of the hook introduces a gap between the crossbar and the hook, facilitating the insertion of a fully looped resistance band 206 onto the hook. Thus, when the resistance band anchor 202 is in use with the resistance band 206, the hook portion of the resistance band anchor 202 ascends above the crossbar.

Furthermore, in some embodiments, the bent configuration of the resistance band anchor 202 extends slightly beyond the width of the crossbar. This intentional design provides a degree of flexibility, such that inadvertent contact or displacement by the user, such as through accidental kicking, allows the hook to yield, thereby mitigating the risk of injury.

Moreover, the capability of the resistance band anchor 202 to swivel can allow for a versatile range of body movements, accommodating various exercise routines with the resistance band 206, and facilitating diverse pulling angles for enhanced workout flexibility. Furthermore, the swivel joint and/or the free-floating mechanism of the resistance band anchor 202 can allow the resistance band anchor 202 to move upon contact, thereby mitigating potential injuries (e.g., on a user's toe).

In some embodiments, an exercise station has multiple (e.g., two, three, or more) resistance band anchors (e.g., two such resistance band anchors 202). As described below in connection with FIG. 13, in some implementations, the resistance band anchors are strategically positioned to minimize obstruction to a user while providing high functionality for exercises that utilize resistance bands.

FIG. 10 illustrates a fully folded exercise station 210 with a pull-up bar in a collapsed configuration, designed for convenient storage, according to one or more embodiments. When the exercise station 210 is in the collapsed state, the pull-up bar is retracted from its free-standing pull-up position and is aligned to function as a carry handle in its folded state. As described above, the exercise station 210 exhibits a pivotal movement allowing it to fold down compactly.

As illustrated in FIG. 10, in some embodiments, the exercise station 210 has wheels 212. For instance, a wheeled mechanism is integrated into the design of the exercise station 210. In some embodiments, the exercise station 210 has a set of wheels (e.g., two or more wheels). Moreover, in some embodiments, the exercise station 210 includes a handle 214. The handle 214 can be strategically placed for ease of handling. For example, in some embodiments, the set of wheels is coupled to one side of a base of the exercise station 210, and the handle is coupled to the opposite side of the base. The handle 214 can facilitate lifting of the exercise station 210 and enable movement (e.g., via the wheels 212) on a ground, floor, or other surface.

This user-friendly configuration contributes to the exercise station 210 being transported between locations without necessitating a user to bear the entire weight of the exercise station 210. The incorporation of wheels and a handle on the base can enhance the portability and maneuverability of the exercise station 210, offering a practical solution for relocation and storage.

FIG. 11 illustrates a portion of the base 220 of a free-standing exercise station, according to one or more embodiments. In some embodiments, the base 220 has a lock mechanism for each foot 224 of the base 220. For example, the base 220 has, for each foot 224, a depressible spring-loaded button 226 positioned in proximity to two distinct holes 228 designed to accommodate upward movement of the spring-loaded button 226. Thus, each lock mechanism of the plurality of lock mechanisms is engageable to secure a foot of the plurality of feet in an extended position or in a stowed position.

As described above, in some implementations, the exercise station incorporates extendable feet 224 that pivot at a hinge point. When the feet are fully deployed into an extended position, the spring-loaded button 226 engages by popping up into one of the holes 228, thereby establishing a secure and stable standing configuration for the exercise station. This design contributes to the exercise station remaining firmly and stably positioned during use.

Conversely, to transition into stowage mode, the user can depress the spring-loaded button 226 and swing the foot 224 fully closed. In this stowed position, the button 226 engages the second hole 228, effectively securing the foot 224 into a compact and portable configuration. This mechanism prevents inadvertent movement of the feet 224 and contributes to the exercise station being securely stowed, facilitating ease of storage and transport.

FIG. 12 illustrates four extended feet 234 on a base 230 of an exercise station, according to one or more embodiments. As shown, each foot features an end cap serving multiple functions, including preventing moisture ingress into the metal tubes of the feet 234 to mitigate corrosion, acting as a safety cover to preclude inadvertent contact with the open end of the metal tube, and functioning as a leveling end cap.

The end cap can securely close the end of the metal foot, providing a protective barrier against environmental elements, particularly moisture, to safeguard against corrosion and maintain the structural integrity of the exercise station. Additionally, the end cap serves as a safety feature, minimizing the risk of injury by covering the exposed end of the opened metal tube.

In some embodiments, beneath or near the end cap, the base 230 includes adjustable levelers (e.g., one for each foot 234). For example, the adjustable leveler is a rotatable wheel-shaped stand. The adjustable levelers 236 allow for upward or downward rotation, thereby facilitating height adjustment of the feet 234. This feature enables users to stabilize and adapt the exercise station to uneven floors or ground surfaces, ensuring that each foot 234 can be individually leveled for a balanced and stable pull-up workout experience.

FIG. 13 illustrates an exercise station 240, with a base 243 having extended feet. In some embodiments, the extended feet feature accessory attachment points 246 (e.g., receiver slots or threaded insert holes), according to one or more embodiments. Also, FIG. 13 illustrates detachable accessory exercise equipment 248 (e.g., push-up handle grip) positioned above the accessory attachment points 246 (e.g., in an exploded view). In some embodiments, the detachable accessory exercise equipment 248 can be securely coupled (e.g., fastened) to the accessory attachment points 246. This arrangement showcases a modular design, allowing for the attachment of various exercise accessories to the base 243 of the exercise station.

The accessory attachment points 246 can be strategically incorporated into the base 243, providing a standardized interface for the attachment of accessory exercise equipment. The detachable accessory exercise equipment 248 can be removably coupled to these accessory attachment points 246, exemplifying the versatility of the exercise station 240. This modular capability enables users to customize their workout experience by adding a variety of exercise accessories, thereby enhancing the functionality and adaptability of the exercise station to accommodate a wide range of calisthenics exercise routines. Examples of detachable accessory exercise equipment include push-up handle grips, sit-up feet holders, Nordic curl accessories, and a squat deck platform.

As mentioned above in connection with FIGS. 9A and 9B, the exercise station 240 can include anchors for coupling resistance bands to the exercise station 240. For example, the exercise station 240 includes a pair of resistance band anchors 202a, 202b on a base bar 244 of the base 243. Moreover, in some implementations, the resistance band anchors 202a, 202b are strategically positioned to minimize obstruction to a user while providing high functionality for exercises that utilize resistance bands. For example, the resistance band anchors 202a, 202b are positioned, respectively, near the stands 241, 242 of the exercise station 240. For instance, the resistance band anchor 202a is coupled to the base bar 244 of the base 243 at an inside location of the base bar 244 closer to the first stand 241 than to the second stand 242. Similarly, the resistance band anchor 202b is coupled to the base bar 244 of the base 243 at an inside location of the base bar 244 closer to the second stand 242 than to the first stand 241. By strategically positioning the anchors, potential stumbling hazards can be prevented.

FIG. 14 illustrates an exercise station 260 with a rectangular frame, featuring two upright stands, according to one or more embodiments. In some embodiments, the stands include multiple holes 264 along their height, allowing for versatile height adjustments. Additionally, two additional U-shaped handles 261, 262 (e.g., dip bars) are illustrated, designed to be inserted into any of the holes 264, providing users with the flexibility to achieve optimal height settings based on their workout preferences.

FIG. 14 emphasizes the adaptability of dip bar routines with the exercise station 260, highlighting the user's ability to customize the height for different exercises. The holes 264 in the stands are clearly illustrated, demonstrating a range of height options available to accommodate a variety of workout routines. For instance, the selectively variable height of the U-shaped handles 261, 262 allows users to adjust heights and angles of body positions for various exercises, such as dips, push-ups, lat pulls, seated dips, and Bulgarian split squats.

This depiction serves to showcase the innovative and adjustable nature of the exercise station 260, offering a practical solution for users to tailor their workout experience by easily inserting the handles 261, 262 into the desired hole(s) for optimal positioning and effectiveness.

FIG. 15A illustrates a top view of the exercise station 260, featuring the U-shaped handles 261, 262 coupled to the stands of the exercise station 260, according to one or more embodiments. The U-shaped handles 261, 262 are each depicted with one tail of the U slanting inward, creating a unique configuration. Positioned in front of the exercise station, the U-shaped handles 261, 262 extend toward the user, forming a rounded bend angled toward them, while the tail extends away. This design allows for versatile grip options, enabling users to perform narrow and wide grip exercises.

To further illustrate, the U-shaped handle 261 has a rounded bend between a post 261a and a first grip 261b, and an additional bend between the first grip 261b and a second grip 261c. Similarly, the U-shaped handle 262 has a rounded bend between a post 262a and a first grip 262b, and an additional bend between the first grip 262b and a second grip 262c. Thus, the U-shaped handles 261, 262 facilitate both narrow and wide grip exercises. For example, the U-shaped handles 261, 262 facilitate dips, standard width push-ups, standard grip push-ups, and lat pulls. Moreover, the U-shaped handles 261, 262 facilitate a range of workouts (e.g., wide grip, narrow grip, and multiple hand hold gripping angles).

Moreover, in some embodiments, the U-shaped handles 261, 262 have different lengths. For example, the U-shaped handle 261 has a post 261a having a first length between a first coupling point (any of the holes on the first stand of the exercise station 260, as depicted in FIG. 14) and a first grip 261b, while the U-shaped handle 262 has a post 262a having a second length between a second coupling point (any of the holes 264 on the second stand of the exercise station 260, as depicted in FIG. 14) and a second grip 262b. As shown, in some implementations, the first length of the first post 261a of the first U-shaped handle 261 is longer than the second length of the second post 262a of the second U-shaped handle 262. The different lengths of the posts of these handles can facilitate better ergonomic grips for exercise routines. In particular, as some embodiments of the exercise station 260 have an asymmetrical design (with one stand longitudinally further away from the user than the other stand, to enable folding the stands at hinges), providing a longer post on one of the U-shaped handles further than on the other can help make the grips of the handles laterally aligned for exercises.

In addition, as shown in FIG. 15A, the U-shaped handles 261, 262 are shaped to support a user's weight centered over the center line of the exercise station 260. For instance, a user doing a dip exercise routine can grip the U-shaped handles 261, 262 at their respective second grips 261c, 262c to position the user's body weight above the base bar and below the pull-up bar to mitigate potential forward or backward tilt of the exercise station 260.

FIG. 15B illustrates a top view of the exercise station 260, featuring alternative U-shaped handles 265, 266 coupled to the stands of the exercise station 260, according to one or more embodiments. The U-shaped handles 265, 266 are each depicted with one tail of the U slanting inward. As depicted, in some embodiments, the U-shaped handles 265, 266 have variable grip diameters. For instance, the U-shaped handle 265 has a fixed grip 265c having a first diameter; and an adjustable grip (e.g., an additional grip selectively insertable over the fixed grip 265c) having a second diameter larger than the first diameter. Similarly, the U-shaped handle 266 has a fixed grip 266c having a first diameter; and an adjustable grip (e.g., an additional grip selectively insertable over the fixed grip 266c) having a second diameter larger than the first diameter.

Clear emphasis is placed on detailing the form of the U-shaped handles 261, 262, 265, and 266, showcasing their distinctive slanted tail, rounded bend, and asymmetrical length. FIGS. 15A and 15B convey the innovative structure of the U-shaped handles 261, 262, 265, 266 that sets them apart in the realm of fitness equipment.

In some embodiments, the hinges of the exercise station have a unique design. In particular, in some embodiments, the hinges have a U-shaped metal cuff (e.g., welded to the hinge). The U-shaped metal cuff can be lined with an inner plastic cuff, such as a U-shaped plastic cuff or an open plastic channel. The plastic cuff can act as a seat for the conjoining metal tube upright when folded, and also can guide the exercise station uprights when opening the exercise station to set up for use. In some embodiments, this unique design is applied at the lower hinges and the middle hinges. In some embodiments, this unique design is applied at all hinges of the exercise station.

In some implementations, the hinges can be tightened, thereby squeezing the metal and inner plastic cuff closer together. This can result in a very stiff folding mechanism due to increased friction. This stiffness is beneficial because it makes unfolding the exercise station easier as the friction bears some of the weight. Moreover, this stiffness also increases safety by preventing the exercise station from crashing downward (e.g., if a user lets go before locking in place).

FIG. 16 illustrates an exercise station 300 in a partially expanded configuration, according to one or more embodiments. The exercise station 300 can support its own weight in this partially expanded configuration. For instance, the stiffness provided by the inner plastic cuff within the U-shaped (e.g., an open channel, also known as a C-shape) metal cuff provides support to keep the exercise station 300 from crashing downward. In some embodiments, the inner plastic cuffs are located within the U-shaped metal cuffs. In the embodiment shown, the inner plastic cuffs within the U-shaped metal cuffs are located at the lower and middle hinges.

To further illustrate, as shown in FIG. 16, the exercise station 300 has a base configured to rest on a floor, a first stand, a second stand, and a pull-up bar. The first stand has a first lower stand member 312 coupled to a first side of the base at a lower end of the first lower stand member 312 via a first lower U-shaped channel hinge 311, and a first upper stand member 314 coupled to an upper end of the first lower stand member 312 at a lower end of the first upper stand member 314 via a first middle U-shaped channel hinge 323. The second stand has a second lower stand member 322 coupled to a second side of the base at a lower end of the second lower stand member 322 via a second lower U-shaped channel hinge 321, and a second upper stand member 324 coupled to an upper end of the second lower stand member 322 at a lower end of the second upper stand member 324 via a second middle U-shaped channel hinge 313. The pull-up bar is coupled to an upper end of the first upper stand member 314 at a first side of the pull-up bar via a first upper hinge 315, and coupled to an upper end of the second upper stand member 324 at a second side of the pull-up bar via a second upper hinge 325.

Moreover, as shown in FIG. 16, the first lower U-shaped channel hinge 311 has a metal open channel 331. Similarly, the first middle U-shaped channel hinge 323 has a metal open channel 343, the second lower U-shaped channel hinge 321 has a metal open channel 341, and the second middle U-shaped channel hinge 313 has a metal open channel 333.

Furthermore, as illustrated, in some embodiments, the hinges are attached (e.g., welded) to one of the stand members and hingedly coupled to another other stand member. For instance, the first middle U-shaped channel hinge 323 is attached to one of the first lower stand member or the first upper stand member (e.g., the first lower stand member 312 in the depicted embodiment), and is hingedly coupled to the other of the first lower stand member or the first upper stand member (e.g., the first upper stand member 314 in the depicted embodiment).

FIG. 17 illustrates a top-side view of a hinge with a metal U-shaped cuff and an inner plastic cuff, according to some embodiments. As also shown, the U-shaped metal cuff and the inner plastic cuff partially surround a stand member of the exercise station, and are coupled to the stand member via a screw or bolt. A nut on the screw or bolt can be tightened to increase the friction on the stand member, thereby increasing the stiffness of the hinge.

To further illustrate, an outer portion of a middle U-shaped channel hinge 313 has a metal open channel 333, and an inner portion of the middle U-shaped channel hinge 313 has a polymer piece 353 positioned between the outer portion and at least one of a lower stand member or an upper stand member (e.g., upper stand member 314 in the depicted embodiment). In some embodiments, the polymer piece 353 is made of plastic. Alternatively, the polymer piece 353 can be rubber or some other material designed to mitigate metal-on-metal friction. By positioning the polymer piece 353 between the metal open channel 333 and the stand member, the polymer piece 353 can lubricate the hinges, thereby providing for smoother expansion and collapse of the exercise station 300, as well as mitigating scratching or screeching sounds that could result from metal-on-metal movement.

Moreover, in some embodiments, each U-shaped channel hinge includes a double shear joint configured to be selectively tightened around a stand member. For example, the middle U-shaped channel hinge 313 includes a screw or bolt 360 that can be tightened or loosened to increase or decrease the resistance of the polymer piece 353 on the upper stand member 314. For instance, a width 362 between opposite sides of the metal open channel 333 can be decreased (or increased) to adjust a tightness of the hinges, and consequently a resistance of the exercise station 300 to expanding or collapsing. In this way, a user can control movement of the stands of the exercise station 300 when folding or unfolding to enhance safety and ease of expansion or collapse.

In some cases, the increased friction between the polymer piece 353 and the upper stand member 314 (due to tightening of the screw or bolt 360) provides a secure hold to the exercise station 300, preventing the pull-up bar from falling if the user releases hold of the exercise station 300 during lifting or lowering. Furthermore, such added friction in the hinges (from tightening the screw or bolt 360 to squeeze the metal open channel 333 and the polymer piece 353 around the upper stand member 314) can make expansion of the exercise station 300 easier for the user, as more weight is carried by the hinges, thus alleviating some of the weight of the exercise station 300 from the user. In addition, a user can configure the hinges (e.g., by tightening or loosening the screws or bolts 360 to a desired torque) such that the exercise station 300 expands or collapses at a controlled speed to enhance safety, assist the user, and provide a smooth setup or folding process.

FIGS. 18A-18C illustrate three views of unique double shear hinges with U-shaped metal cuffs welded to members of the exercise station 300, according to some embodiments. In FIG. 18A, a middle U-shaped channel hinge 313 is shown with a bolt 360 through the hinge portion of the assembly. The outer U-shaped metal cuff (e.g., the metal open channel 333) is shown, with a dashed area representing (hidden from view) an inner U-shaped plastic cuff (e.g., the polymer piece 353).

As shown, when the exercise station 300 is in the expanded state, the middle U-shaped channel hinge 313 is seated directly against the first lower stand member 312 and the first upper stand member 314. For example, the middle U-shaped channel hinge 313 accommodates the first upper stand member 314, providing a secure seating arrangement for the exercise station 300 during both storage and use, and maintains contact with the first upper stand member 314 during expansion and collapse of the exercise station 300.

In FIG. 18B, a lower U-shaped channel hinge 311 is shown, which also utilizes a unique double shear hinge assembly, with axis point 311a shown. The outer U-shaped metal cuff (e.g., the metal open channel 331) is shown, with a dashed area representing (hidden from view) an inner U-shaped plastic cuff (e.g., the polymer piece 351).

Additionally, FIG. 18B shows a first lock mechanism 371 (e.g., a latch or clamp) and a second lock mechanism 372 (e.g., a pin) that engage the lower stand member in a locked state with the base.

FIG. 18C provides an additional view of the middle U-shaped channel hinge 313. In this view, the upper stand member 314 is nearly at the expanded configuration. The outer U-shaped metal cuff (e.g., the metal open channel 333) is shown with the inner U-shaped plastic cuff (e.g., the polymer piece 353). The inner U-shaped plastic cuff contacts the upper stand member 314 (e.g., a metal tube) when the upper stand member 314 is folded down in the hinge.

Additionally, FIG. 18C shows a first lock mechanism 373 (e.g., a latch or clamp) and a second lock mechanism 374 (e.g., a pin) that engage the upper stand member 314 in a locked state with the lower stand member 312.

FIGS. 19A and 19B depict an exercise station 250 with an adjustable height. To illustrate, FIG. 19A depicts the exercise station 250 with a first stand 251 and a second stand 252 in a first configured with first overall height, while FIG. 19B depicts the exercise station 250 with the first stand 251 and the second stand 252 in a second configuration with a second overall height that is larger than the first overall height. Thus, in some embodiments, an overall height of the exercise station 250 is selectively changeable to accommodate different desired heights for the pull-up bar (e.g., when a tall user prefers the pull-up bar to be higher).

To further illustrate, in some embodiments, the first stand 251 and the second stand 252 each have a telescoping portion 254 that raises the pull-up bar higher upon extension. For example, the overall height of the exercise station 250 can increase as shown with additional height 256 in FIG. 19B. Moreover, in some implementations, the first stand 251 and the second stand 252 each have a lock mechanism 258 that secures the stands at the extended height. For example, a pin or clamp can lock the telescoping portion 254 at a raised position above a standard position. In some embodiments, the telescoping portions 254 extends into upper stand members of the first stand 251 and the second stand 252, while not reaching the middle hinges to allow the exercise station 250 to fold into the collapsed configuration.

As mentioned above in connection with FIG. 13, in some embodiments, the exercise station accommodates accessory equipment. To illustrate an additional example, FIG. 20 shows the exercise station 240 with a platform 249 (e.g., a squat deck) in an exploded view. The platform 249 can be coupled to the base 243 of the exercise station 240. For example, the platform 249 can be coupled to feet on a side of the exercise station 240 via the accessory attachment points 246.

In some implementations, the platform 249 includes anchors 247 for resistance bands, similar to the resistance band anchors described above. For example, the anchors 247 receive a resistance band to couple the resistance band to the platform 249 and provide a user with increased resistance for a squat exercise routine or other exercise routine. Furthermore, in some embodiments, the platform 249 includes one or more accessory attachments, such as a foot anchor for sit-ups or Nordic leg curls.
