Description

DOORFRAME EXERCISE DEVICECROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority benefit of U.S. Provisional Application No. 63 / 461,066, filed April 21, 2023, the disclosure of which is herein incorporated by reference in its entirety.TECHNICAL FIELD

[0002] This disclosure relates generally to the field of exercise devices and methods, and more specifically to the field of multi-configuration exercise devices.BACKGROUND

[0003] Pull-up bars provide a stable and reliable platform for performing a variety of upper body exercises, primarily pull-ups and chin-ups. The user grips the bar with their hands, palms facing either towards or away from their body, and pulls their body weight upwards until their chin clears the bar. This exercise targets the muscles of the back, shoulders, arms, and core, helping to improve strength, endurance, and muscle definition in these areas. Pull- up bars are quickly and easily installed, and by only requiring a doorframe, these exercise devices are extremely popular means for at-home exercise.

[0004] Due to the rigid and un-adjustable nature of pull-up bars, the optional exercises that can be performed on conventional pull-up bars are primarily chin-ups and pull-ups.SUMMARY

In some embodiments, the lower frame may include one or more handles to engage with the exercise device(s) and allow the user to perform exercises (e.g., pull-ups, chin-ups, dips, etc.). The exercise devices described herein include at least two configurations. In a first configuration, referred to herein as a collapsed configuration, the exercise device includes a minimum length in which the lower frame 20 of the exercise device is arranged at a greatest distance 304 (shown in FIG. 1) from the floor associated with a door frame (e.g., door frame 15 of FIG. 1) in which the exercise device may be installed. In such a configuration, the lower frame 20 may be used for upper body pulling exercises, such as pull-ups and chin-ups.In a second configuration, referred to herein as a fully extended configuration, the exercise device includes a maximum length in which the lower frame 20 of the exercise device is arranged at the lowest distance 304 (shown in FIG. 1) from the floor associated with the door frame 15. In such a configuration, the lower frame 20 may be used for upper body pushing exercises (e.g., dips). Length of the device is defined as measured from a point on the upper frame to a point on the lower frame. Some embodiments described herein may include a plurality of adjustment positions between the first configuration and the second configuration.

[0086] FIG. 1 illustrates an embodiment of a doorframe exercise device 100. The device 100 includes an upper frame 10 for attaching the device to a doorframe 15, a lower frame 20 including one or more handles, and a telescoping mechanism 30 coupling the upper frame 10 to the lower frame 20. The telescoping mechanism 30 may be used to adjust the length 300 of the device 100. The lower frame 20 may include a cross-member 122 (shown in FIGs. 2-9) to brace the exercise device 100 against the doorframe 15. The cross-member 122 (shown in FIGs. 2-9) may include a length 310 (shown in FIG. 3) greater than the width of the doorframe 15. As such, the cross-member 122 may brace the device 100 when in use. For example, a user may apply force to a handle of the lower frame 20 with leverage about a point of the upper frame 10, and the cross-member 122 may brace the device 100 while the device experiences such loading.

[0087] The upper frame 10 may couple to the doorframe 15 in a variety of different ways. For example, the upper frame 10 may include portions specifically shaped to fit over the top of the trim of the doorframe 15. For example, the upper frame 10 may include portions specifically shaped to fit over the top of the trim of the doorframe 15 such that upper frame 10 distributes weight evenly across the portion of the trim in which the upper frame engages. The upper frame 10 may include a first portion (e.g., ledge 522 shown in FIG. 6) for engagement with a first side 19 (shown in FIG. 2) of the doorframe 15 and a second portion (e.g., ledge 554 for engagement with a second side (not shown) of the doorframe 15. The upper frame 10 may include an adjustable dimension between the first portion (e.g., ledge 522 shown in FIG. 6) and the second portion (not shown) of the upper frame 10.

[0088] The telescoping mechanism 30 includes a minimum adjustment length and a maximum adjustment length, and as such the exercise device 100 may be arranged at a minimum length (i.e., a first configuration) or a maximum length (i.e., a second configuration) based at least in part on an adjustment or arrangement of one or moretelescoping mechanism 30 associated with device 100. Some embodiments may include a telescoping mechanism 30 with a plurality of adjustment positions between the maximum adjustment length and the minimum adjustment length, resulting in the device 100 including a plurality of lengths 300 between the minimum length (i.e., first configuration) and the maximum length (i.e., second configuration). The telescoping mechanism 30 (also known as a collapsible mechanism) may include one or more assemblies of nested tubular sections (e.g., sections 220, 222, etc.) that can be extended (e.g., expanded) or retracted (e.g., collapsed) to adjust the length 300 of the exercise device 100. Further, the tubular sections of the one or more assemblies of nested tubular sections may be square tubing, cylindrical tubing, oval tubing, triangular tubing, hexagonal tubing, elliptical tubing, trapezoidal tubing, etc. In some embodiments, the telescoping mechanism 30 may include one or more hollow portions defined by the upper frame 10 in which the one or more assemblies of nested tubular sections may collapse within one or more other tubular sections when the exercise device 100 is in the first configuration. Further, the telescoping mechanism 30 may include one or more posts coupled to the lower frame 20 which may collapse into the one or more hollow portions defined by the upper frame 10.

[0089] In some embodiments, the telescoping mechanism 30 may include one or more hollow portions defined by the lower frame 20 in which the one or more assemblies of nested tubular sections may collapse within when the exercise device 100 is in the first configuration. Further, the telescoping mechanism 30 may include one or more posts coupled to the upper frame 10 which collapse into the one or more hollow portions defined by the lower frame 10. The one or more telescoping assemblies 112 (i.e., collapsible assemblies) of nested tubular sections may include a post 216 (shown in FIG. 6) nested within a hollow portion defined by tube 212; a post 216 nested within a first intermediate tube 214 nested within a hollow portion defined by tube 212; a post 216 nested within a first intermediate tube 214 nested within a second intermediate tube (not shown) nested within a hollow portion defined by tube 212; a post 216 nested within a first intermediate tube 214 nested within a second intermediate tube 214 nested within a third intermediate tube nested within a hollow portion defined by tube 212; etc.

[0090] FIG. 2 illustrates another embodiment of a doorframe exercise device 100. The doorframe exercise device 100 includes an upper frame 110 for attaching the device 100 to a doorframe 15, a telescoping mechanism including a first telescoping assembly 112 and a second telescoping assembly 114, a lower frame 120 including a first adjustable handle 116and a second adjustable handle 118, and a cross-member 122 coupled to the lower frame 120. The upper frame 110 of the device 100 is illustrated as attached to the upper portion 306 of the doorframe 15. The upper frame 110 rigidly secures the doorframe exercise device 100 to the upper portion 306 of the doorframe 15, such that the device 100 properly supports a user during exercises.

[0091] As shown in FIG. 6, the upper frame 110 includes a first beam 520 rigidly coupled to a first angled tube 512 and rigidly coupled to a second angled tube 518. The upper frame 110 further includes a second beam 522 rigidly coupled to a first tube 212 and rigidly coupled to a second tube 218. The first tube 212 is rigidly coupled to a first perforated column 412 that defines a plurality of holes 524. The second tube 218 is rigidly coupled to a second perforated column 418 that defines a plurality of holes 526. The upper frame 110 may be assembled by nesting the first perforated column 412 into the first angled tube 512, while nesting the second perforated column 418 into the second angled tube 518. The first angled tube 512 defines a hole 528 for selective alignment with the plurality of holes 524 of the first perforated column 412. The first angled tube 512 may be locked with respect to the first perforated column 412 with a pin 532 passing through the defined hole 528 of the first angled tube 512 and through a selectably aligned hole of the plurality of holes 524 of the first perforated column 412. The second angled tube 518 defines a hole 530 for selective alignment with the plurality of holes 526 of the second perforated column 418. The second angled tube 518 may be locked with respect to the second perforated column 418 with a pin 534 passing through the defined hole 530 of the second angled tube 518 and through a selectably aligned hole of the plurality of holes 526 of the second perforated column 418. Selectable engagement of the hole 528 of the first angular tubing 512 with the plurality of holes 524 of the first perforated column 412 and selectable engagement of the hole 530 of the second angular tubing 518 with the plurality of holes 526 of the second perforated column 418 allows for an adjustable width 210 (shown in FIG. 8) between the first beam 520 and the second beam 522. The adjustable width 210 of the upper frame 110 may be adjustable to fit a range of doorframe depths. For example, width 210 may be adjustable from about 7 cm to about 20 cm; about 9 cm to about 19 cm; about 10 cm to about 18 cm; about 11 cm to about 17 cm; etc.

[0092] Referring again to FIG. 6, the first beam 520 may be coupled to the first angled tube 512 and coupled to the second angled tube 518 such that the first beam 520 includes a ledge 552 for engagement with an upper surface 18 (shown in FIG. 2) of the doorframe 15 and trim16 of a first side 19. The second beam 522 may be coupled to the first tube 212 and coupled to the second tube 218 such that the second beam 522 includes a ledge 554 for engagement with an upper surface of the doorframe 15 trim of a second side (not shown). With the upper frame 110 being adjustable in width 210 (shown in FIG. 8), ledge 552 and ledge 554 can be made to engage with the top of the doorframe 15 and trim, such that the upper frame 110 can removably couple the doorframe exercise device 100 to doorframes of varying depths.

[0093] As shown in FIG. 2, once the doorframe exercise device 100, in a collapsed configuration or first configuration, is attached to the upper portion 306 of the doorframe 15, the device 100 may be used for exercises that utilize ample distance 304 (shown in FIG. 1) from lower frame 120 to the floor (e.g., pull-ups, chin-ups, etc.). The lower frame 120 includes a plurality of gripping portions for a user to grip the lower frame 120 during exercises. For example, and shown in FIG. 3, the lower frame 120 may include a first grip 510a, a second grip 510b, a third grip 510c, a fourth grip 510d, a fifth grip 510e, and sixth grip 51 Of If force is applied to the grip portions of the lower frame 120 these forces would act with leverage upon the upper frame 110. As can be further appreciated in FIG. 3, the effective leverage of forces applied to the lower frame 120 increases with the increased length 300 of the device in a fully expanded configuration. The cross-member 122 of the lower frame 120 may include a length 310 (shown in FIG. 2) greater than the width 302 of the doorframe 15. As such, the cross-member 122 may brace the lower frame 120 against the doorframe 15 to reduce leverage of forces applied to the lower frame 120.

[0094] The exercise device 100 includes mechanisms to reduce the distance 304 (shown in FIG. 1) from the floor associated with the doorframe 15 to thereby provide portions of device 100 as structure for other desired exercises. The first telescoping assembly 112 and the second telescoping assembly 114 allow adjustment of the length 300 of the device 100. As shown in FIGs. 3, 4, and 6, the first telescoping assembly 112 includes a first post 216 coupled to the lower frame 120, intermediate tube 214 in which first post 216 is nested within, and a hollow portion defined by tube 212 in which intermediate tube 214 is nested. Tube 212 may include a locking mechanism 704 for selectably coupling tube 212 to intermediate tube 214 nested within tube 212. Intermediate tube 214 may include a locking mechanism 109 for selectably coupling intermediate tube 214 to the first post 216 nested within intermediate tube 214. In some embodiments, intermediate tube 214 may define a plurality of holes for selective engagement with locking mechanism 704 (e.g., pin type locking mechanism). For example, locking mechanism 704 may engage with the intermediatetube 214 at the first hole 113a, the second hole 113b, the third hole 113c, the fourth hole 113d, or the fifth hole 113e. In some embodiments, the first post 216 may define a plurality of holes for selective engagement of the locking mechanism 109. For example, locking mechanism 109 may engage with the first post 216 at the first hole I l la, the second hole 11 lb, the third hole 111c, or the fourth hole 1 l id. The second telescoping assembly 114 includes a second post 222 coupled to the lower frame 120, intermediate tube 220 (i.e., extension tube 220) in which second post 222 is nested within, and a hollow portion defined by tube 218 in which tube 220 is nested within. Tube 218 may include a locking mechanism 706 for selectably coupling tube 218 to intermediate tube 220 nested within tube 218. Intermediate tube 220 may include a locking mechanism 209 for selectably coupling intermediate tube 220 to the second post 222 nested within intermediate tube 220. In some embodiments, intermediate tube 220 may define a plurality of holes for selective engagement with locking mechanism 706 (e.g., pin type locking mechanism). For example, locking mechanism 706 may engage with the intermediate tube 220 at the first hole 115a, the second hole 115b, the third hole 115c, the fourth hole 115d, or the fifth hole 115e.

Dimension 308 and 309 may be in a range of about 6 cm to about 30 cm; about 8 cm to about 25 cm; about 10 cm to about 20 cm; etc.

[0097] FIG. 9 illustrates another embodiment of a doorframe exercise device 400. The exercise device 400 includes an upper frame 410 for attaching the device 400 to a doorframe, a lower frame 420 including two handles 416, 419, a cross-member 122, and a telescoping mechanism 430 for adjusting the length 300 (shown in FIG. 1) of the device 400. The exercise device 400 includes handles 416, 419 fixed to, or integrally formed from, the lower frame 420. As such, handles 416, 419 are fixed with respect to the lower frame 420.

[0098] Locking mechanisms have been described thus far as engagement of a pin through selective aligned holes but other locking mechanisms for fixing a nested tube or post within another tube are herein contemplated. For example, FIG. 11 A illustrates a clutch tube lock mechanism 604a. The locking mechanism 604a includes a clutch (i.e., a friction-based system) that creates friction between the outer tube 606a and the inner tube 602a. The mechanism 604a includes a pad or ring (not shown) made of rubber, plastic, or metal and a threaded collar 850a that applies or relieves pressure to the pad or ring depending on which direction the collar is rotated. When a user extends the telescopic tubes 602a, 606a to a desired length, the collar 850a may be tightened such that the pad or ring is forced into the interface of the inner tube 602a and the outer tube 606a, thus locking the inner tube 602a and the outer tube 606a with respect to each other.

[0099] For example, FIG. 1 IB illustrates a split collar lock 604b. The locking mechanism 604b includes a collar 850b fixed to the outer tube 606b and includes a split collar 852b selectively engageable with the inner tube 602b. As such, a user may extend the telescopic tubes 602b, 606b to a desired length, and the split collar 852b may be tightened such that the inner tube 602b is frictionally locked by the split collar 852b, thus locking the inner tube 602b and the outer tube 606b with respect to each other.

[0100] For example, FIG. 11C illustrates a clamp lock 604c. The locking mechanism 604c includes a clamp fixed to the outer tube 606c. As such, a user may extend the telescopic tubes 602c, 606c to a desired length, and the clamp lock 604c may be clamped such that the inner tube 602c is frictionally locked by compressing the outer tube onto the inner tube 602c, thus locking the inner tube 602b and the outer tube 606b with respect to each other.

[0101] For example, FIG. 1 ID illustrates a cam lock 604d. The locking mechanism 604d may be fixed to the inner tube 602d inside of the outer tube 606d. When the inner tube 602d is twisted in a first direction with respect to the outer tube 606d, the cam lock 604d is forced into secure engagement with the inside of the outer tube 606d, thus locking the inner tube 602d and the outer tube 606d with respect to each other. To release the cam lock 604d, the inner tube 602d is twisted in a second direction with respect to the outer tube 606d.

[0102] For example, FIG. 1 IE illustrates a push-button pin lock 604e. The locking mechanism 604e may be fixed to the inner tube 602e and the push-button pin 850e is biased toward the outer tube 606e (e.g., spring-loaded). The outer tube 606e may include a plurality of holes longitudinally distributed along the outer tube 606e. The push-button pin 850e may be pressed into the outer tube 606e, allowing the inner tube 602e to slide with respect to the outer tube 606e until the push-button pin 850e engages a preceding or succeeding hole of the plurality of holes of the outer tube 606e, at which point the outer tube 606e and the inner tube 602e are locked together.

[0103] For example, FIG. 1 IF illustrates a friction lock 604f. The locking mechanism 604f may be fixed to the outer tube 606f and may include a threaded plunger (not shown) for selective engagement with the inner tube 602f. As such, a user may extend the telescopic tubes 602f, 606f to a desired length, and the friction lock 604f may be tightened such that the inner tube 602f is frictionally locked by compressing the inner tube 602f with the threaded plunger, thus locking the inner tube 602f and the outer tube 606f with respect to each other.

[0104] For example, FIG. 11G illustrates a spring-loaded pin lock 604g. The locking mechanism 604g is coupled to the outer tube 606g and includes a spring-loaded pin 850g biased toward the inner tube 602g. The inner tube 602g defines a plurality of holes longitudinally distributed along the inner tube 602g for engagement with the spring-loaded pin 850g. A user may pull the spring-loaded pin 850g out of engagement with a hole of the inner tube 602g and extend the telescopic tubes 602g, 606g to a desired length, once released the spring-loaded pin 850g may engage with a hole of the plurality of holes of the inner tube 602g, locking the outer tube 606g and the inner tube 602g together.

[0105] It has been contemplated herein that telescoping assemblies described herein may include defined hollow portions, intermediate tubes, and posts with varying diameters such that the clearance between the nested assembly decreases to or near zero in the fully extended configuration. For example, and with reference to FIG. 3, post 216 of a telescope assembly 112 may include a portion of outer diameter which is greater than or equal to aportion of the inner diameter of the intermediate tube 214 in which the post 216 is nested, and the intermediate tube 214 may include an outer diameter portion greater than a portion of an inner diameter portion of the hollow portion defined by tube 212. As such, the telescoping assembly 112 will stop at a fully extended configuration in which the clearance between the post 216 and the intermediate tube 214, and the clearance between the intermediate tube 214 and the hollow portion defined by tube 212 have both reached zero.

[0106] Doorframe exercise devices described herein may include anchors for use of other exercise elements (e.g., elastic bands, etc.). For example, the doorframe exercise device 400 shown in FIG. 9 includes a plurality of anchors: a first anchor 870a, a second anchor 870b, a third anchor 870c, a fourth anchor 870d, a fifth anchor 870e, and a sixth anchor 870f. The plurality of anchors may be used to attach other exercise elements, such as elastic bands, to the device 400.
