BACKGROUND OF THE INVENTION
1. The Field of the Invention
The present invention generally relates to exercise apparatuses. More specifically, the present invention generally relates to strength training exercise apparatuses that can be packaged and shipped in a substantially pre-assembled manner.
2. The Relevant Technology
Strength training systems having one or more exercise stations linked to a resistance assembly have been around for some time. Strength training systems are often large and made of numerous different parts. In order to reduce the cost associated with packaging, storing, and shipping, strength training systems are packaged in an unassembled manner. Packaging strength training systems in an unassembled manner reduces the size of the box required to enclose the system, thus reducing the packaging costs and the amount of storage space required to store the system.
While packaging strength training systems in an unassembled manner provides some benefits as described above, there are however, various drawbacks to packaging and shipping strength training devices is an unassembled manner. For example, when a strength training system is shipped in an unassembled manner to a user, the user must assemble the strength training system. Such assembly can be complicated. Often, strength training systems are shipped with an instructional manual to assist the user is assembling the strength training system. However, even with the aid of an instructional manual, the complications associated with assembling the strength training system are not eliminated.
Additionally, assembling a strength training system often requires the use of various tools. If a user does not have the required tools, assembly of the system could be further complicated or made impossible. To avoid these complications, a user could purchase the required tools, the tools could be included with the strength training system, or the user could hire someone to perform the assembly. However, such accommodations would increase the costs associated with obtaining the strength training system. Additionally, even with the required tools, assembly of the strength training system takes a significant amount of time.
In light of the foregoing limitations, there is a continuing need for exercise apparatuses that overcome the above shortcomings.
BRIEF SUMMARY OF THE INVENTION
In general, embodiments of the invention are concerned with a strength training exercise device that, among other things, has various components that can be selectively moved between a packaged orientation and a use orientation without requiring extensive assembly or the use of tools. Embodiments of the present invention can be packaged in a substantially pre-assembled manner in which the size of the packaging is generally the same size as the packaging of strength training devices that are not pre-assembled. In one embodiment of the invention, a cabling system is linked to a resistance assembly and at least one exercise station when the exercise device is packaged.
In one exemplary embodiment of the invention, a strength training device is provided having a frame, a resistance assembly, and at least one exercise station. The frame includes a base portion for providing stability to the strength training device. The base portion can include at least one stability base member that can be moved, such as rotated, between a packaged position and a use position. In one embodiment, the stability base member can be in the packaged position when it is positioned parallel to a main base member. The stability base member can be in the use position when it is angled away from the main base member. The stability base member can be secured in the use position with the use of a fastener, such as a screw or bolt.
An exemplary embodiment of the present invention provides a strength training device having at least one exercise station coupled to the frame and the resistance assembly. The exercise station can be moved between a packaged position and a use position to facilitate packaging and shipping of the strength training device in a substantially pre-assembled manner without substantially increasing the size of the packaging and the costs associated therewith. For example, in one embodiment, the exercise station is an press arm assembly having a first press arm and a second press arm. First and second press arms are rotatably coupled to the frame such that they can be selectively moved from a packaged position, in which they are positioned adjacent the frame, to a use position in which they are rotated away from the frame such that a user can engage them during exercise.
An exemplary embodiment of the present invention further provides a locking mechanism that substantially prevents undesired movement of an exercise station between the packaged position and the use position. The locking mechanism can include i) a locking member with at least one guide member, and ii) and an end cap having at least one opening adapted to receive the guide member(s). In use, when the guide member(s) are received within the openings of the end cap, the exercise station is locked in the use position and cannot be moved to the packaged position. However, the locking mechanism can be unlocked by withdrawing the guide member(s) from the openings in the cap, thus allowing the exercise station to be moved from the use position to the packaged position. The locking mechanism can also include a biasing member, such as a spring, to bias the locking mechanism toward the locked position.
An exemplary embodiment of the present invention provides a resistance assembly mounted on or coupled to the frame and linked to the exercise station. The resistance assembly can include a cable and pulley system, one or more weight stacks, one or more resilient rods, a rotation-activated resistance device, a resistance mechanism having a pivoting arm and resistance member, or any combination thereof. The present invention allows for the cable and pulley system to link one or more exercise stations to the resistance assembly when the strength training device is in the packaged position and in the use position. The resistance assembly is adapted to provide resistance to a user of the strength training device as the user engages the exercise station. The resistance assembly can also be at least partially enclosed by a shroud. The shroud can be made from a flexible, resilient material such that if an object presses against it, the shroud will slightly deform, but will regain its previous form when the object is removed.
These and other objects and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 discloses a strength training system 10 according to one embodiment of the invention. Strength training system 10 is configured to be collapsible, such that strength training system 10 can be packaged and shipped in a pre-assembled manner. Furthermore, strength training system 10 can be packaged in a container having relatively the same size as a typical container for a similarly sized strength training system.
Packaging strength training system 10 in a pre-assembled manner without increasing the container size can provide benefits for the user. For example, the time required to transition strength training system 10 from the container to usable form is reduced. A user is able to remove strength training system 10 from its container and utilize strength training system 10 in less time because strength training system 10 is pre-assembled. Therefore, the assembly stage typically required for strength training systems is removed or otherwise simplified. Likewise, strength training system 10 does not require a larger container, thus maintaining shipping and storage size and cost with similarly sized and shaped strength training systems. In this manner, a user can quickly and efficiently utilize strength training system 10 after removal from its container, without having to pay for additional shipping and storage expense due to an increased container size. In one embodiment, a cable and pulley system can link a resistance assembly to at least one exercise station when the strength training system 10 is in its container, whether for shipping or storage. In this manner, the strength training system 10 can be utilized without substantial assembly after it is removed from its shipping and/or storage container.
Furthermore, the configuration of strength training system 10 enables a user to reorient strength training system 10 from a storage or packaged orientation and substantially secure strength training system 10 in a use orientation without the use of tools. The ability to reorient and secure strength training system 10 in a use orientation, or in other words, an orientation where strength training system 10 is usable for exercise, provides many benefits. For example, a user is able to quickly and efficiently utilize strength training system 10 after it is removed from its container, and user is not required to have or utilize tools to do so. Likewise, a user can quickly and efficiently reorient strength training system 10 for use or for storage without requiring the use of tools. In this manner, tools are not necessitated in order reorient strength training system 10.
With reference now to FIGS. 1 and 2, strength training system 10 can be configured to be collapsible, thereby enabling strength training system 10 to be packaged in a pre-assembled manner without increasing the size of its storage and shipping container. In the illustrated embodiment, strength training system 10 includes a frame 12, at least one and preferably a plurality of exercise stations 14, 16 and/or 18, a resistance assembly 20, and a cable and pulley system 22 linking exercise stations 14, 16 and 18 to resistance assembly 20.
Frame 12 is configured to provide structural support for strength training system 10. Frame 12 can comprise a metal material, such as steel or aluminum, or can comprise some other structural material such as reinforced plastic or composite, or some combination thereof. According to one embodiment of the invention, frame 12 comprises a base 24, an upper member 26, and an upright member 28 coupling upper member 26 to base 24. Base 24 is configured to provide stability to strength training system 10. In the illustrated embodiment, base 24 comprises a main base member 34, a plurality of stability members 36a, 36b and a rear base member 38.
Main base member 34 can be sized and configured to accommodate portions of cable and pulley system 22 therein, and/or to enable at least a portion of cable and pulley system 28 to link to resistance assembly 20. Main base member 34 can also be sized and configured to provide positioning and support for upright member 28 and resistance assembly 20. For example, upright member 28 is positioned at one end of main base member 34, and at least a portion of resistance assembly 20 is positioned on and supported by the opposite end of main base member 34, as illustrated. In one embodiment, main base member 34 is a steel, hollow rectangular elongate member.
In the illustrated embodiment, stability members 36a, 36b are pivotally coupled to upright member 28 by brackets 40a, 40b. Stability members 36a, 36b are linked to main base member 34 through brackets 40a, 40b and upright member 28. Stability members 36a, 36b can be sized and configured to provide stability to strength training system 10 when stability members 36a, 36b are in a use position, as illustrated in FIG. 1. Stability members 36a, 36b can be substantially prevented from pivoting by additionally securing stability members 36a, 36b to brackets 40a, 40b by use of fasteners 44a, 44b, respectively. Stability members 36a, 36b can be positioned at an angle with respect to main base member 34, or can be pivoted toward main base member 34 to be in a storage or packaged orientation, such that stability members 36a, 36b are substantially parallel to main base member 34. Rear base member 38 can be removably coupled to main base member 34. Rear base member 38 can be sized and configured to provide additional stability to strength training system 10. Base 24 further serves as a support for resistance assembly 20 and upright member 28.
It will be understood by one of ordinary skill in the art in view of the disclosure provided herein that the stability members 36 can be linked to the main base member 34 or upright member 28 by various configurations without departing from the scope and spirit of the invention. For example, in one embodiment, stability members 36 are removably coupled to brackets 40 by a fastener, or in other words can be selectively coupled to and detached from brackets 40 by a pin and lock, a bolt, such as a wing nut, a latch mechanism, or some other type of fastener. In another embodiment, stability members 36 can telescope from main base member 34 and then pivot in order to provide a stabilizing function. In yet another embodiment, stability members 36 can be pivotally linked to upright member 28 so as to be substantially parallel to upright member 28 when in a stored, shipping or otherwise non-use orientation, and then can rotate downward and be secured to provide a stability function.
In the illustrated embodiment, upright member 28 is coupled to base 24 and extends upward from base 24. Upright member 28 is configured to couple various components of strength training system 10 to frame 12. For example, exercise station 14, a back rest 30 and a head rest 32 are removably coupled to upright member 28. Furthermore, various portions of cable and pulley system 22 are coupled to upright member 28 to facilitate linking of exercise stations 14, 16 to resistance assembly 20. Upright member 28 can further comprise a plurality of protrusions 74 configured to facilitate coupling of exercise station 14 to frame 12. In one embodiment, protrusions 74 can comprise a rod positioned through the side walls of upright member 28 such that terminating ends of the rod extend away from upright member 28 in a perpendicular fashion, for example.
In one embodiment, upright member 28 comprises a steel tubular elongate member coupled to main base member 34 via a weld. Brackets 40a, 40b can also be coupled to upright member 28 via a weld. However, brackets 40a, 40b and/or main base member 34 can be coupled to upright member 28 by other means. For example, main base member 34 and/or brackets 40a, 40b can be coupled to upright member 28 by a fastener, such as a bolt or rivet.
According to one embodiment of the invention, upper member 26 is coupled to the upper end of upright member 28 in a similar fashion as brackets 40a, 40b and/or main base member 34 are coupled to upright member 28. Upper member 26 can comprise a steel, hollow, rectangular elongate member, thus allowing at least a portion of cable and pulley system 22 to be supported and partially housed thereby. For example, at least one pulley of cable and pulley system 22 is rotatably coupled to upper member 22 and at least partially housed therein, as illustrated. Upper member 26 can be in the same vertical plane as main base member 34.
Upper member 26 can be configured to provide support for resistance assembly 20. In the illustrated embodiment, resistance assembly 20 is coupled to one end of upper member 26. With the upper end of resistance assembly 20 coupled to upper member 26 and the lower end of resistance assembly 20 coupled to main base member 34, resistance assembly 20 can be secured relative to frame 12. Furthermore, upper member 26 can provide support to exercise stations 16 and 18. In the illustrated embodiment, exercise station 16 is rotatably coupled to upper member 26 and exercise station 18 is coupled to cable and pulley system 22, a portion of which is rotatably coupled to upper member 26. In this manner, upper member 26 can support exercise station 16 and exercise station 18. Exercise station 16 can be rotatably coupled to upper member 26.
Strength training system 10 can include at least one exercise station, and preferably a plurality of exercise stations 14, 16 and 18. In this embodiment, strength training system 10 includes a leg station designated as 14, such as a leg extension mechanism, an press arm designated as 16, and an arm pull down or lat pull, designated as 18. Leg station 14 can be removably coupled to upright member 28. In this manner, leg station 14 can be selectively attached and detached from upright member 28 at the users convenience.
Press arm 16 is rotatably coupled to frame 12. A portion of press arm 16 can be moved downward with respect to upper member 26, as illustrated in FIGS. 5, 7A and 7B, and then rotated toward resistance assembly 20, as illustrated by the arrow in FIG. 6. Rotating press arm 16 toward resistance assembly 20 can position press arm 16 in a storage or packaged orientation. Leg station 14, press arm 16, and arm pull 18 are linked to resistance assembly 20 by cable and pulley system 22 in order to provide resistance for a user during exercise. Arm pull 18 can be linked to cable and pulley system 22 by a clip or removable fastener, thereby enabling a user to quickly connect or disconnect arm pull 18 from the cable of cable and pulley system 22. Through the use of a clip, for example, arm pull 18 can be connected to or disconnected from cable and pulley system 22 without the use of tools, thereby facilitating the quick and efficient utilization of strength training system 10 after removal from a container.
While the illustrated embodiment discloses specific exercise stations, it will be understood in light of the disclosure provided herein that various other exercise stations may be incorporated without departing from the spirit and scope of the invention. For example, other exercise stations can include an arm curl bar, a pull-up bar, an arm cuff or collar, a leg cuff or collar, a butterfly mechanism, a rotating mechanism, a sliding mechanism, a lifting mechanism, a stepper mechanism, or some other mechanism or assembly which can be contacted by a portion of a user's body for purposes of strength training and/or exercise, for example.
Resistance assembly 20 is configured to provide resistance for a user during exercise. In one embodiment, resistance assembly 20 is a weight stack linked to cable and pulley system 22 in an adjustable manner, thereby enabling a user to modify the amount of weight utilized during a given exercise. A variety of different types of resistance assemblies can be utilized with out departing from the spirit and scope of the invention. For example, resistance assembly can include any one of the following or some combination thereof: one or more weight stacks, the resistance mechanism as disclosed in U.S. Pat. No. 6,685,607 entitled EXERCISE DEVICE WITH RESISTANCE MECHANISM HAVING A PIVOTING ARM AND A RESISTANCE MEMBER, the contents of which are hereby incorporated by reference, a rotation-activated resistance device as disclosed in U.S. Pat. No. 5,147,265 entitled ROTATION-ACTIVATED RESISTANCE DEVICE, the contents of which are hereby incorporated by reference, or a mechanism which utilized the weight of the user for resistance.
Resistance assembly 20 is coupled to frame 12 and linked to cable and pulley system 22. Resistance assembly 20 is linked to exercise stations 14, 16 and 18 by cable and pulley system 22. Cable and pulley system 22 comprises at least one cable and a plurality of pulleys. Cable and pulley system 22 is configured to link exercise stations 14, 16 and 18 to resistance assembly. With cable and pulley system 22 being coupled to exercise stations 14, 16 and 18, and exercise stations 14 and 18 being selectively removable, and exercise station 16 being rotatable, strength training system 10 can be packaged in a pre-assembled manner thereby providing many benefits to the user.
With reference now to FIG. 3, frame 12 includes stability members 36a, 36b to facilitate packaging of strength training system 10 in a pre-assembled manner. The ability to package strength training system 10 in a pre-assembled manner enables the user to transition strength training system 10 from its packaged orientation, as illustrated in FIG. 8, to a usable orientation, as illustrated in FIGS. 1 and 2, in a quick and efficient manner. Furthermore, the container used to store and ship strength training system 10 does not need to be substantially increased in order to accommodate for strength training system's pre-assembled state, thereby reducing additional shipping and storage costs associated with larger containers. The cable of cable and pulley system 22 has been suppressed in FIGS. 3-8 to facilitate illustration of other details of strength training system 10.
In the illustrated embodiment, stability members 36a, 36b are pivotally coupled to main base member 34 and upright member 28 by brackets 40a, 40b. Brackets 40a, 40b each comprise a pin hole 42a, 42b on their top and bottom surfaces through which a pin can be positioned in order to secure stability members 36a, 36b to brackets 40a, 40b. The pin can be positioned in pin hole 42a in the top surface of bracket 40a, through stability member 36a and then in a corresponding pin hole in the bottom surface of bracket 40a. In this manner, stability member 36a is able to pivot about pin hole 42a. Utilizing a pin positioned in pin holes 42a of bracket 40a enable pivoting of stability member 36a. For example, stability member 36a can be rotated in the direction of the arrow so as to be substantially parallel to main base member 34. When stability member 36a is pivoted to be substantially parallel to main base member 34, as illustrated in FIG. 4, stability member 36a would be considered in its storage or packaged orientation. Brackets 40a, 40b further comprise an aperture 48a, 48b for use in substantially securing stability members 36a, 36b in the use orientation.
Strength training system 10 can further comprise fasteners 44a, 44b, 44c. Stability member 36a can be substantially secured in a usable orientation, as illustrated in FIGS. 1 and 2, by use of fastener 44a. Stability member 36a can include an aperture 46a configured to receive and substantially retain fastener 44a therein. Fastener 44a can comprise a threaded elongate shaft, such as a bolt, which threads can correspond with threads of aperture 46a such that fastener 44a and aperture 46a can engage in a bolt and nut type engagement. For example, in one embodiment, fastener 44a comprises a bolt and aperture 46a comprises a corresponding nut welded to the inner surface of stability member 36a. In the illustrated embodiment, fastener 44a comprises a wing-shaped head. Wing-shaped head of fastener 44a can be sized and configured to be engaged or gripped by a user thereby enabling a user to twist or rotate fastener 44a. Aperture 48a can be sized and configured to receive threaded portion of fastener 44a therein and prevent wing-shaped head from passing therethrough.
A user can secure stability member 36a in the use orientation by pivoting stability member 36a until engagement with bracket 40a is achieved, as illustrated in FIGS. 1 and 2, inserting threaded portion of fastener 44a into aperture 48a, and rotating fastener 44a to engage aperture 46a of stability member 36a until wing-shaped head of fastener 44a engages or contacts bracket 40a. Similarly, to position stability member 36a in a storage or packaged orientation, a user can rotate fastener 44a in an opposite direction to disengage the threaded portion of fastener 44a from aperture 46a of stability member 36a, remove fastener 44a from aperture 48a of bracket 40a, and then rotate stability member 36a toward main base member 34 until stability member 36a is positioned against main base member 34, as illustrated in FIG. 4.
While reference has been made specifically to stability member 36a, stability member 36b can be configured, secured, utilized and oriented in a similar manner as stability member 36a, given that in the illustrated embodiment stability member 36b is a mirror image of stability member 36a. In this manner, a user is able to reorient stability members 36a, 36b and substantially secure stability members 36a, 36b in their use orientation absent the use of tools. Likewise, a user is able to reorient stability members 36a, 36b in the storage or packaged orientation without using tools.
Referring now to FIG. 4, frame 12 further comprises a bracket 50 configured to facilitate securement of rear base member 38 to main base member 34. Bracket 50 can be sized and configured to receive a portion of rear base member 34 therein to facilitate securement and positioning of rear base member 34 with respect to other frame members. In the illustrated embodiment, bracket 50 comprises an aperture 52 and a plurality of guide members 54a, 54b. Aperture 52 is configured in a similar fashion as apertures 46a, 46b of stability member 36a, 36b respectively. Likewise, fastener 40c is configured in a similar fashion as fasteners 40a, 40b. In this manner, aperture 52 and fastener 40c can be sized and configured for engagement like a nut and corresponding bolt. Guide members 54a, 54b are sized and configured to facilitate positioning of rear base member 38.
In the illustrated embodiment, rear base member 38 comprises a plurality of apertures 56, 58a and 58b. Aperture 56 can be sized and configured in a similar fashion as aperture 48a of bracket 40a. Apertures 58a, 58b can be sized and configured to correspond to guide members 54a, 54b, respectively, such that guide member 54a can be received in aperture 58a and guide member 54b can be received in aperture 58b. In this manner, rear base portion 38 can be secured to main base member 34 by positioning guide members 54a and 54b in apertures 58a, 58b, respectively, inserting fastener 40c in aperture 56 of rear base member 38, and rotating fastener 40c so as to engage the threaded portion of fastener 40c with aperture 52 until the front face of rear base member 38 engages the rear exposed portion of bracket 50 and wing-shaped portion of fastener 40c engages the rear face of rear base member 38.
Further illustrated in FIG. 4 is stability member 36a oriented in a storage or packaged orientation. Similar to how stability member 36a, 36b can be reoriented and secured without using tools, rear base portion can be selectively secured and removable by utilizing fastener 40c. The ability to secure rear base portion 38 to main base member 34, and remove or disengage rear base portion 38 therefrom without tools facilitates the quick and efficient utilization by user of strength training system 10 after removal from a container or from a storage orientation.
FIG. 5 illustrates exercise station 14, back rest 30, and head rest 32 being disconnected from frame 12. Exercise station 14, back rest 30, and head rest 32 are configured to be selectively coupled to and selectively removable from frame 12 without the use of tools. In the illustrated embodiment, exercise station 14 comprises a leg extension member 60 pivotally linked to a leg extension frame 62 by a bracket 64 coupled to leg extension frame 62, and a seat 66. The cable of cable and pulley system 22 can extend from an opening in upright member 28, as illustrated in FIG. 1, and couple to leg extension member 60. Cable can be coupled to leg extension member 60 by being fastened to a ring 68 on leg extension member 60. Alternatively, cable can be removably coupled to leg extension member 60 by a clasp or clip, thereby allowing a user to selectively disconnect cable from leg extension member 60, if desired. In this manner, cable and pulley system 22 is configured to link leg extension member 60 to resistance assembly 20 to thereby enable a user to utilize exercise station 14 for exercise and/or strength training.
Leg extension frame 62 is configured to provide support for a user positioned on seat 66. Leg extension frame 62 is further configured to enable exercise station 14 to be selectively coupled to or detached from frame 12 without the use of tools. For example, leg extension frame 62 can comprise a mating member 70 configured to correspond to and mate with the surface of upright member 28, as illustrated in FIGS. 1-2 and 4. Leg extension frame 62 can further include engagement members 72 configured to engage protrusions 74 of upright member 28, as illustrated in FIGS. 2 and 4. With engagement members 72 engaging protrusions 74, and mating member 70 engaging and mating with upright member 28, as illustrated in FIGS. 2 and 4, a user can be positioned on seat 66 and thereby supported by frame 12.
The configuration of and connectivity between leg extension frame 62 and protrusions 74 of upright member 28 enable a user to removably couple exercise station 14 to frame 12 without the use of tools. Likewise, the removable coupling of exercise station 14 to frame 12 facilitates the quick and efficient reorientation of strength training system 10 between a use orientation and a storage or packaged orientation. For example, the configuration of exercise station 14 and upright member 28 enables a user to couple exercise station 14 to frame 12 for use in exercise in a quick and efficient manner without the use of tools. Alternatively, exercise station 14 can be detached from frame 12 without utilizing tools. Exercise station 14 is detached from frame 12 by moving leg extension frame 62 upward to disengage engagement members 72 from protrusions 74. Thereafter, mating surface 70 can be moved away from upright member 28 thereby disconnecting or detaching exercise station 14 from frame 12.
When exercise station 14 is disconnected from frame 12, as illustrated in FIG. 5, seat 66 and leg extension frame 62 can be rotated vertically, for example, to be substantially in line with leg extension member 60, and exercise station 14 positioned proximate upright member 28 for storage or packaging, as illustrated in FIG. 8. In this manner, leg extension member 60 can remain coupled to cable and pulley system 22 while packaged in a container, thereby, at least in part, facilitating the pre-assembled nature of the strength training system 10.
Strength training system 10 can further comprise an exercise station 76 removably coupled to leg extension frame 62. In the illustrated embodiment, exercise station 76 is not coupled or linked to cable and pulley system 22. Rather, exercise station 76 can be used as a support for exercises. For example, exercise station 76 can be an arm support for an exercise known as the preacher curl. Exercise station 76 can comprise a cushioned support member 78 and an elongate support member 80 coupling cushioned support member 78 to leg extension frame 62.
Elongate support member 80 can be sized and configured to be received into a corresponding opening in leg extension frame 62 adjacent bracket 64, thereby enabling exercise station 76 to be selectively removable. In this manner, exercise station 76 can be moved upward with respect to leg extension frame 62 to remove elongate support member 80 from the opening in leg extension frame 62. Likewise, exercise station 76 can be coupled to leg extension frame 62 by aligning elongate support member 80 with opening of leg extension frame 62 and moving elongate support member 80 downward, for example, to position elongate support member 80 in opening of leg extension frame 62. Exercise station 14 links exercise station 76 to frame 12 of strength training system 10. In this manner, exercise station 76 can be selectively connected or linked to frame 12 or disconnected from frame 12 and/or exercise station 14 without the use of tools.
