This invention relates to the field of exercise racks. More particularly, this invention relates to a spring release for an accessory mount used for mounting accessories to an exercise rack and for positioning the accessories at selected heights on the exercise rack.
In the description that follows, the term “exercise rack” is used broadly to include any sort of structure intended to support exercise weights, including squat racks, press racks, and the like. Certain exercise racks include left and right vertical members with pairs of mounting locations provided along the length of the vertical members for mounting accessories to the vertical members. For example, bar catch accessories for supporting an exercise bar, such as a barbell, provided with or without weights, may be placed onto the exercise rack. The and left and right bar catches are mounted to the vertical members and may be moved to various mounting locations to support the barbell at various heights. The height of the bar may need to be adjusted based on the type of exercise being performed. For example, the exercise bar may be placed at a low position in the rack with respect to the floor surface and used for bench press exercises. At other times, the exercise bar may be placed at a higher position in the rack with respect to the floor surface and used for squats or overhead press exercises. In addition to transitioning from one type of exercise to another, another reason that the bar might be moved from a first vertical position to a second vertical position on the rack is to accommodate multiple users of the rack that are of varying heights. Other accessories, such as safety bars, may also be mounted to the vertical members of the exercise rack. These bars are often used to support a loaded barbell during rest periods, such as between sets, and also to catch the bar in an accidental drop.
One problem with mounting accessories to an exercise rack using the methods described above is that vertically adjusting the accessory is time consuming. Vertically adjusting the accessory often requires that the accessory be disconnected from the vertical members, repositioned, and then reconnected to the vertical members. This can be a difficult and dangerous process, which could result in the accessory being dropped and or damaged in the process. Another problem is that only the bar catches and safety bars can be mounted to the vertical members of the exercise rack, and other accessories cannot typically be mounted to the rack. Thus, the vertical members provided limited utility.
Accordingly, what is needed is an exercise rack and accessory mount that provides for faster and safer vertical adjustment of an accessory on the rack and that allows for greater flexibility in the types of accessories that can be mounted to the rack.

The terms “comprising”, “having”, “including” and “containing” are to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise noted. The terms “substantially”, “generally” and other words of degree are relative modifiers intended to indicate permissible variation from the characteristic so modified. The use of such terms in describing a physical or functional characteristic of the invention is not intended to limit such characteristic to the absolute value which the term modifies, but rather to provide an approximation of the value of such physical or functional characteristic.
Terms concerning attachments, coupling and the like, such as “attached”, “connected” and “interconnected”, refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both moveable and rigid attachments or relationships, unless otherwise specified herein or clearly indicated as having a different relationship by context. The term “operatively connected” is such an attachment, coupling or connection that allows the pertinent structures to operate as intended by virtue of that relationship.
The use of any and all examples or exemplary language (e.g., “such as” and “preferably”) herein is intended merely to better illuminate the invention and the preferred embodiments thereof, and not to place a limitation on the scope of the invention. Nothing in the specification should be construed as indicating any element as essential to the practice of the invention unless so stated with specificity.
The above and other problems are addressed by an exercise rack accessory apparatus having an accessory carrier configured to slide along a portion of an exercise rack and to reposition an accessory mounted to the accessory carrier. The apparatus includes a stationary handle, which is fixedly mounted to the accessory carrier by one or more first spacers, and a moving handle, which is mounted to the accessory carrier by one or more second spacers, and is configured to allow the moving handle to be moved between an engaged position and a disengaged position while the moving handle is located between the stationary handle and the accessory carrier. Each second spacer includes a barrel having an open end mounted to the accessory carrier and an opposing closed end with an opening formed therein. A shaft extends through the barrel, out of the closed end via the opening, and is mounted to the moving handle. A pin end is located on the shaft opposite the end mounted to the moving handle. The pin end is configured to slide at least partially into the barrel via the open end when the moving handle is moved to the disengaged position and at least partially out of the barrel via the open end, through the accessory carrier, and to engage a portion of the exercise rack when the moving handle is moved to the engaged position. Engaging the pin end with the exercise rack prevents relative movement of the accessory carrier with respect to the exercise rack in order to fix the accessory carrier at the selected position on the exercise rack. Lastly, the apparatus include a biasing member that is compressed when the moving handle is moved to the disengaged position. The biasing member biases the moving handle to the engaged position to automatically lock the accessory carrier in place.
Further advantages of the invention are apparent by reference to the detailed description when considered in conjunction with the figures, which are not to scale so as to more clearly show the details, wherein like reference numerals represent like elements throughout the several views, and wherein:
Referring now to the drawings in which like reference characters designate like or corresponding characters throughout the several views, there is shown in
As it is used in this description, the term “accessory” is used broadly to refer to a device that is mounted to a portion of an exercise rack, including particularly those devices mounted to or between vertical members of the exercise rack, such as J-hooks (i.e., bar catches), safety catches, pull-up bars, and the like.
As shown in
The accessories shown in
On the other hand,
These accessories 300 are adjustable in length. This adjustability enables the accessories 300 to fit between vertical members that are spaced at varying distances apart. The adjustability also simplifies the installation process by allowing the accessories to be shortened while being placed between the vertical members and then extended to mount the mounting plates 304 to the exercise rack. The use portion 302 of these accessories 300 includes a first horizontal member 310 having a hollow interior and that is open on one end. A second horizontal member 312 is configured to slide into the hollow interior of the first horizontal member 310 via the open end. The size of the accessory 300 may be increased or decreased by sliding the second horizontal member 312 out of or into the first horizontal member 310. The amount of relative member between the horizontal members 310, 312 may be limited by engaging a first limiting member 314 with a second limiting member 316. In this particular case, the first limiting member 314 is an elongate slot formed into the first horizontal member 310. The second limiting member 316 is a detent extending outwards from the second horizontal member 312 that is configured to slide within the slot (i.e., first limiting member) 314.
The accessories 300 described above are shown mounted to an exercise rack 102 in
Tracks 114 are mounted to multiple of the vertical rack members 108. The tracks 114 are typically arranged in pairs, with one track disposed on a right side of the rack 102 and a corresponding track located on a left side of the rack. This configuration enables an elongate weight bar, such as a barbell, to be supported at opposite ends by accessories 300, such as J-hooks or safety bars, mounted to tracks 114. Generally, these tracks 114 are mounted to front and back surfaces of the vertical rack members 108. This allows opposite ends of exercise bars to be supported by the exercise rack 102 such that the accessory extends between two adjacent vertical rack members 108. However, a single track 114 (i.e., not a pair) may be mounted the exercise rack 102. Also, tracks 114 may be mounted to surfaces other than the front and back of the vertical rack members 108 (e.g., sides of the vertical members). Each track 114 includes an elongate rectangular bar-shaped carrier guide 116. The carrier guide 116 is mounted to the vertical rack members 108 and serves as an interface that connects the accessory carrier 200 to the exercise rack 102. Each track 114 also includes a retention bar 117, which includes a plurality of spaced apart notches 118 formed therein, that extends vertically and substantially along the length of the track. As discussed below, the accessory carrier 200 is fixed at a selected vertical location by engaging it with the notches 118 of the retention bar 117. An offset O is provided between the carrier guide 116 and the vertical rack member 108 by mounting the retention bar 117 between the carrier guide and the vertical member. This offset O allows the accessory carrier 200 to contact a front surface 116A and a rear surface 116B of the carrier guide in order to securely mount the accessory carrier to the track 114. Accordingly, the accessory carrier 200 serves a dual purpose of mounting an accessory to the exercise rack 102 and also vertically positioning the accessory on the exercise rack.
With reference to
On the first side 202, elongate bar-shaped first spacers 212 extend along each of the left and right sides of the central plate 210 on either side of the channel 205. The first spacers 212 are divided vertically lengthwise, having a thick outer portion 212A, including mounting holes 220, on one side of the divide and a comparatively thinner inner portion 212B on the opposite side of the divide. The first spacers 212 are spaced apart from one another and arranged so that the inner portions 212B are nearest the center of the central plate 210. The outer portions 212A are along the outer left and right edges of the central plate 210 such that the mounting holes 220 of each is aligned. A second set of elongate bar-shaped spacers 214 is mounted to the first set of spacers 212. The second spacers 214 are approximately the same size and dimensions as the outer portion 212A of the first spacers 212. First retainers 216A, 216B are mounted to the second set of spacers 214. The first retainers 216A, 216B are wider than the second spacers 214 such that a portion of the first retainers extend inwards beyond the second spacers. As a result, parallel vertical slots 215 are formed along the left and right sides of the channel 205. On one side of the channel 205, the slot 215 is defined by an elongate bar-shaped first retainer 216A, a second spacer 214, and the inner portion 212B of a first spacer 212. On the opposite side of the channel 205, the other slot 215 is defined by a pair of smaller first retainers 216B, a second spacer 214, and the inner portion 212B of a first spacer 212. As discussed further below, a space is provided between upper and lower first retainers 216B and a carrier lock 232 is mounted in that space.
The accessory carrier 200 is mounted to the track 114 by placing the carrier guide 116 into the channel 205 with left and right edges of the mounting carrier guide located in the left and right slots 215. As such, the first retainers 216A, 216B are sized to fit within the offset O between the carrier guide 116 and the vertical rack member 108. The first retainers 216A, 216B slide along one side of the carrier guide 116 and prevent the accessory carrier 200 from being removed from the carrier guide 116 of the track 114. Likewise, the inner portion 212B of the first spacers 212 slides along the opposite side of the carrier guide 116 and guide carrier guide along the track 114. The channel 205 has a first portion with a width D1 that is formed between inner surfaces of the two second spacers 214. The carrier guide 116 is sized to fit within the space between the two second spacers 214. Therefore, the carrier guide 116 has a width less than D1. Also, the combined thickness of the outer portion 212A of the first spacers 212 and the second spacers 214 is greater than the thickness of the carrier guide 116. As a result, the accessory carrier 200 slides along the track 114 with the carrier guide 116 positioned within the space between the second spacers 214. The channel 205 further includes a second portion with a width D2 that is formed between inner surface of the first retainers 216A, 216B. As mentioned earlier, a primary purpose of the first retainers 216A, 216B is to prevent the accessory carrier 200 from being removed from the carrier guide 116 of the track 114. Accordingly, the carrier guide 116 has a width greater than D2, such that, if pulled away from the track 114, the carrier guide contacts the first retainers 216A, 216B and the accessory carrier 200 maintains its connection with the track.
As mentioned earlier, the retention bar 117 connects the vertical rack member 108 to the carrier guide 116. As such, the first retainers 216A, 216B of the accessory carrier 200 are spaced apart such that the retention bar 117 of the track 114 can extend through that space and mount to the carrier guide 116. Therefore, the retention bar 117 has a width less than D2. When raised or lowered, the accessory carrier 200 slides along the track 114 with the retention bar 117 positioned within the space between the first retainers 216.
With reference to
The upper and lower first retainers 216B act as rotation limiting members to limit the degree of rotation that the carrier lock 232 can undergo. When the carrier lock 232 is in first (i.e., locked) position, its rotation is limited by contacting an outer face of the lower first retainer 216B. In the second (i.e., unlocked) position, the carrier lock 232 is prevented from rotating too far by contacting the upper first retainer 216B. The carrier lock 232 may be configured to also an inner face of the lower first retainer 216B.
As a safety feature, the carrier lock 232 may be biased to automatically rotate to the first (i.e., locked) position. In this particular embodiment, the handle 236 is heavier than the locking tip 238, which causes the carrier lock 232 to rotate about the pivot point 234 to the first (i.e., locked) position. In other embodiments, a spring or other similar biasing means may be provided to cause the carrier lock to be automatically rotated to the first (i.e., locked) position. To further assist the carrier lock 232 to be correctly positioned in the first (i.e., locked) position, the retention bar 217 may have contoured front sections 119 located above each of the notches 118 that slope inwards towards the notch 118. As the accessory carrier 200 is lowered, the locking tip 238 is automatically rotated so that it comes into contact and follows along the contoured section 119 and is correctly located within a notch 118. These are safety features that assist in correcting locking the accessory carrier 200 in place and, more importantly, arresting unintentional downwards movement (i.e., drops) of the accessory carrier. Preferably, when the auto-biasing carrier lock 232 is used, sustained downwards movement of the accessary carrier 200 is only possible when the carrier lock is intentionally held by a user in the second (i.e., unlocked) position by a user.
As another safety feature, the carrier lock 232 may be further provided with an upwardly extending tooth 240 that engages with a corresponding downwardly-extending tooth 242 located along a top surface of each of the notches 118 at the lower end of the contoured section 119 when the accessory carrier 200 is raised. When the teeth 240, 242 are engaged with one another, the carrier lock 232 is prevented from rotating from the first (i.e., locked) position to the second (i.e., unlocked) position. To unlock the carrier lock 232, a user is required to lift the accessory carrier 200 and then rotate the carrier lock 232 to the second (i.e., unlocked) position using then handle 236. The purpose of this safety feature is to prevent the carrier lock 232 from accidentally rotating to the second (i.e., unlocked) position and the accessory carrier falling downwards as a result (e.g., if the accessory carrier is bumped or gets caught on the user).
With reference to
As a safety feature, the accessory carrier 200 may include a safety stop 246 for preventing the accessory 300 from accidentally disengaging from the accessory carrier. The safety stop 246 is rotatably mounted to the accessory carrier 200 via pivot point 248 and includes a user contact portion 250 disposed on one side of the pivot point and a locking tip 252 disposed on an opposite side of the pivot point. The safety stop 246 is configured to move between a second (i.e., unlocked) position, where the accessory 300 is permitted to freely slide into and out of the slot 222, and a first (i.e., locked) position, where the accessory is prevented from disengaging from the slot. Preferably, when the accessory 300 contacts the locking tip 252 of the safety stop 246, the safety stop is moved automatically to the second (i.e., unlocked) position. As a result, the accessory 300 is able to freely slide into the slot 222 because the mounting plate 304 automatically moves the safety stop 246 to the second (i.e., unlocked) position as it slides by.
Additionally, the safety stop 246 is preferably biased to the first (i.e., locked) position so that it automatically returns to the first (i.e., locked) position after the mounting plate 304 has been inserted into the slot 222 sufficiently far in order to secure the mounting plate within the slot. In this particular embodiment, the user contact portion 250 is heavier than the locking tip 252, which causes the safety stop 246 to rotate about the pivot 248 to the first (i.e., locked) position. In other embodiments, a spring or other similar biasing means may be provided to cause the safety stop 246 to be automatically rotated to the first (i.e., locked) position.
In the first (i.e., locked) position, the locking tip 252 may simply top surface of the mounting plate 304 of the accessory 300. However, in other embodiments, the mounting plate 304 may be provided with one or more notches 308 formed in a top surface of the lip portion 306, and the locking tip 252 of the safety stop engages the notch in the first (i.e., locked) position. In preferred embodiments, the mounting plate 304 is provided with notches 308 located on both the left and right sides of the top surface of the mounting plate 304. This allows the same accessory 300 to be used interchangeably in accessory carriers 200 with either left or right-located safety stops 246.
With reference now to
An accessory, such as accessory 300, may be fixedly or removably mounted to the accessory carrier 322. The accessory carrier 322 is designed to carry and reposition the accessory 300 on the exercise quickly and without requiring the accessory carrier to be removed from the exercise rack. Preferably, the accessary carrier 322 is designed to allow the accessory to be repositioned using only one hand. The accessary carrier 322 has a pair of handles, including a stationary handle 326 and a moving handle 332. As detailed below, these handles 326, 332 are grasped simultaneously by one of user's hands to both release the accessory carrier from its locked or engaged configuration and to reposition it while in a disengaged position. Releasing the moving handle 332 locks the accessory carrier 322 in place at a selected height. The stationary handle 326 includes a palm contact surface 328 (located on the right-hand side of the stationary handle, as shown in
The stationary handle 326 is fixedly mounted to an outer surface of the accessory carrier 322 by one or more first spacers 330. The moving handle 332 is movably mounted to an outer surface of the accessory carrier by one or more second spacers 336. The stationary handle 326 and the moving handle 332 may each be mounted to the accessary carrier 322 by a single spacer 330, 336. In the illustrated embodiment, both ends of each of the stationary handle 326 and moving handle 332 are mounted to the rear plate 340 of the accessary carrier 322 by spacers 330, 336. Preferably, the stationary handle 326 and first spacers 330 are sized to surround the moving handle 332 and second spacers 336 on three sides (top, bottom and right sides, as shown in
Referring now to
The exercise rack accessory apparatus 320 also includes a lock 339 and, more preferably, a pair of locks 339. The locks 339 are designed to be engaged and disengaged in response to movement of the moving handle 332. When the moving handle 332 is in the engaged position, the locks 339 engage a portion of the exercise rack that is located in the guide channel 324 and, through that engagement, prevent relative movement of the accessory carrier 322 with respect to the exercise rack. When the moving handle 332 is in the disengaged position, the locks 339 are disengaged from the exercise rack and movement of the accessory carrier 322 with respect to the exercise rack is permitted.
In the illustrated embodiment, the locks 339 are formed as part of the second spacers 336. The second spacers 336 include a barrel 344 having an open end 344A and a closed end 344B, and an opening is formed in the closed end of the barrel. In this particular case, a threaded cap 350 having an opening formed in it is threaded into a threaded end of the barrel 344 to close the end of the barrel. Each lock 339 includes a pin end 346 that is mounted to an end of a shaft 348. In the illustrated case, the shaft 348 of the lock 339 extends through the barrel 348 and then out of the barrel via the opening formed in the cap 350. The shaft 348 then extends through another opening that is formed at an end of the moving handle 332. A nut 352 is then threaded onto a threaded end of the shaft 348 and tightened against the moving handle 332 to removably mount the moving handle to the second spacer 336.
In the illustrated embodiment, the open end 344A of the barrel 344 opens into the guide channel 324. When the moving handle is moved from the disengaged position to the engaged position, the lock 339 slides through the barrel 344 and the pin end 346 extends out of the open end 344A and into the guide channel 324. When the moving handle 332 is in engaged position, the pin end 346 is inserted into one of several vertically-disposed openings 354 (or other similar structure) that are provided along vertical rack member 108. In this configuration, the accessory carrier 322 (and the accessory 300) are locked at the selected vertical position on the exercise rack. Pulling back on the moving handle 332 towards the disengaged position causes the lock 339 to disengage from the exercise rack. When the locks 339 disengage from the exercise rack, the accessory carrier 322 (and the accessory 300) can slide vertically upwards or downwards along vertical rack members 108.
In preferred embodiments, the moving handle 332 is biased to the engaged position. This functions as a safety feature because biasing the moving handle 332 to the engaged position will cause the lock to automatically engage and stop moving if it were dropped. Therefore, certain embodiments include a spring 356 or its functional equivalent that biases the moving handle 332 towards the engaged position. In the illustrated embodiment, the spring 356 is located in the barrel 344 and surrounds the shaft 348 of the lock 339. In this particular case, one end of the spring 356 bears an internal shoulders 358 formed at the pin end 346 of the lock 339. The opposite end of the spring 356 bears against another internal shoulder 360 located inside the barrel 344. The spring 356 is compressed as the moving handle 332 is moved towards the disengaged position. Preferably, the spring 356 is always at least slightly compressed between shoulders 356 and 360, including when the moving handle 332 in the disengaged position and the engaged position. This ensures that the lock 339 is never loose.
Although this description contains many specifics, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments thereof, as well as the best mode contemplated by the inventor of carrying out the invention. The invention, as described herein, is susceptible to various modifications and adaptations as would be appreciated by those having ordinary skill in the art to which the invention relates.
