TECHNICAL FIELD
The present disclosure relates to exercise equipment. More particularly, the present disclosure relates to elliptical type exercise devices that include a folding mechanism.
BACKGROUND
There are many types of exercise machines available for individuals to utilize in maintaining physical fitness. Many people have obtained exercise machines for their home so that they can exercise at their convenience without having to travel to a gym or other remote location. Home exercise equipment may include, for example, free weights, weight stacks, resistance weights, treadmills, stationary bicycles and elliptical machines.
While each type of equipment provides certain benefits, elliptical machines are popular with many individuals because they are considered to be a non-impact exercise which is easy on the joints of an individual. Generally speaking, conventional elliptical machines include alternating reciprocating foot supports configured to traverse or travel about a closed path to simulate a striding, running, walking, and/or a climbing motion for the individual using the machine. Each reciprocating foot support conventionally has one end supported for rotational motion about a pivot point, with the other end supported in a manner configured to cause the reciprocating foot support to travel or traverse a closed path, such as a reciprocating elliptical or oblong path or other similar geometric outline. During operation of the elliptical machine, each reciprocating foot support is caused to travel or traverse the closed path, thereby simulating a striding motion of the user for exercise purposes. The reciprocating foot supports are conventionally configured to be out of phase with one another by 180° in order to simulate a proper and natural alternating stride motion.
An individual may utilize an elliptical exercise machine by placing his or her feet onto the reciprocating foot supports and actuating the exercise machine to cause the reciprocating foot supports to repeatedly travel their respective closed paths. This action effectively results in a series of strides achieved by the individual to obtain exercise, with a low-impact advantage. An elliptical exercise machine may further comprise mechanisms or systems for increasing the resistance of the motion. In addition, the reciprocating motion of the feet to achieve a series of strides may be complemented by a reciprocating movement of the arms, whether assisted by the exercise machine via a suitably configured mechanism or system, or unassisted.
Elliptical machines may be configured as a “front mechanism” or a “rear mechanism” type machine. Such a designation indicates where the rotating mechanism (typically a flywheel) attached to the foot supports is located—i.e., at the front of the machine or at the rear of the machine. The location of the rotating mechanism typically has an impact on the path of the foot supports. For example, a front mechanism is often considered to produce a longer, flatter stride, while a rear mechanism is considered to produce a more circular path that includes more elevation change within the path. To a certain degree, the issue of choosing an elliptical machine with either a rear mechanism or a front mechanism is a matter of choice by the user.
One of the inherent characteristics of an elliptical machine is the inherently large size of such equipment. In other words, elliptical exercise machines typically occupy a substantial amount of space within a room and require even more space for proper operation. While space is not a major issue in most commercial settings, such as athletic fitness or sports centers, spas, resorts, etc., the same is not true when the exercise machine is intended for residential use. It is noted that, when in a residential setting, elliptical machines are typically not in use for the majority of the day and, thus, simply consume space for the majority of their existence.
There have been a variety of attempts to provide an elliptical exercise machine that is also “space saving” in some aspect or another. However, such attempts have often resulted in some type of compromise in the overall design of the machine or have not provided the performance or the convenience expected by an end user.
Examples of elliptical machines that have been configured to fold, in an attempt to save space during non-use of the elliptical machine include those described by U.S. Pat. No. 7,775,940 to Dalebout et al., U.S. Pat. No. 6,190,289 to Pyles et al. and PCT Patent Application Publication No. WO2008138124 to Spark Innovations, Inc. The Pyles patent describes an elliptical machine having a front mechanism, wherein foot supports and related components are pivotable upwards toward the control panel/display to be placed in a storage position or state. The Dalebout patent appears to describe an elliptical machine having a rear mechanism, wherein various components are decoupled or disconnected in order to “fold” the elliptical machine into a storage position (and reconnected in order to be placed back into a useable state). The Spark Innovations publication appears to describe an elliptical machine with a rear mechanism wherein the reciprocating arms require adjustment to their positions in order to be transitioned between a useable state and the stored state.
In view of the foregoing, it would be desirable to provide an elliptical exercise machine that maintains all of the beneficial operational functions of prior related elliptical exercise machines while in operation, but that also is capable of substantially reducing the space being occupied by the elliptical exercise machine in a given room when it is not in use.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, an elliptical exercise machine 100 is shown and described. The elliptical exercise machine 100 includes a first assembly 102 operatively coupled with a second assembly 104. The first assembly 102 includes a longitudinal frame member 106 coupled with a first foot or cross member 108 and a second foot or cross member 110. A rear drive/resistance mechanism 112 (referred to herein as the rear mechanism 112 for convenience) is coupled with the frame member 106 and may include, for example, a flywheel and a resistance mechanism as will be appreciated by those of ordinary skill in the art. The resistance mechanism may include a magnetic braking mechanism, sometimes referred to as an eddy current brake, to provide a desired level of resistance to the user during operation of the exercise machine 100. While described in connection with an exercise bicycle, one example of a flywheel, as well as an associated magnetic braking mechanism, is described by U.S. Patent Application Publication No. 2012/0088638 to Lull (application Ser. No. 13/267,719), the disclosure of which is incorporated by reference herein in its entirety.
The lower assembly 102 further includes a first reciprocating foot support 114 and a second reciprocating foot support 116. The first foot support 114 has a first end 118 and a second end 120, the second end 120 being pivotally coupled with the rear mechanism 112 such that the second end 120 of the foot support 114 travels in a substantially circular path during operation of the elliptical machine 100. A foot pad 122 is disposed on the first foot support at a location between the first end 118 and the second end 120. The foot pad 122 is sized and configured to receive and support a foot of a user and may either be integrally formed with the foot support 114 or formed as a separate component and coupled with the foot support 114 (e.g., by fasteners, adhesive, or other mechanical or material techniques). The second reciprocating foot support 116 likewise includes a first end 124 and a second end 126, with the second end 126 being pivotally coupled with the rear mechanism 112 such that the second end 126 of the foot support 116 travels in a substantially circular path during operation of the elliptical machine 100. A second foot pad 128 is disposed on the second foot support 116 at a location between the first end 124 and the second end 126.
The first and second reciprocating foot supports 114 and 116 are laterally spaced apart from one another such that each of the corresponding foot pads 122 and 128 receive the right and left feet, respectively, of a user for facilitating a striding motion with the user during use of the machine 100. The foot pads 122 and 128 may be configured with surface features (e.g., ribs, grooves, knobs, etc) to provide traction to the foot of a user. In other embodiments, while the foot pads may not necessarily include surface features, they may include a non-slip material to provide traction to the foot of a user. The foot pads 122 and 128 may be adjustable relative to their associated foot supports 114 and 116 such that they may be positioned at different locations along the lengths of the foot supports 114 and 116 to accommodate the preferences of different users.
The first assembly 102 may include a number of additional components or features. For example, a handle 130 may be coupled with front cross member 108 to assist in lifting or moving the elliptical machine 100. Additional handles may be coupled to other portions of the elliptical machine 100 to further enable a user to more easily lift or move the elliptical machine 100. One or more wheels 132 may be coupled to the rear cross member 110 to enable a user to more easily move the elliptical machine 100 from one location to another by, for example, lifting on the front handle 130 and rolling the elliptical machine 100 across the floor. Additionally, feet or support pads 134 may be coupled to various portions of the first assembly 102 and may be configured to engage the floor or a supporting surface. The support pads 134 may be adjustable so that the elliptical machine 100 may be leveled on a given surface prior to operation by a user.
The second assembly 104 includes an upright frame member 140 with a control panel 142 coupled therewith. The control panel 142 may include a variety of input devices 144 (e.g., switches, buttons, touch pads) and output devices 146 (e.g., graphic displays, lights, audio speakers) to facilitate control of the elliptical machine 100. The input devices 144 may be used to turn the elliptical machine 100 on or off, to control the amount of resistance being applied to the flywheel of the rear mechanism 112, to enable preset exercise programs, or to otherwise control the operation of the elliptical machine. The various output devices 146 may be used to provide a user with an indication of the operating status of the elliptical machine 100 and to provide other information (e.g., time exercised, calories burned, etc.) to the user.
A variety of additional components may also be coupled with the frame member 140. For example, a tray 148, which may include a cup holder or other structure, may be coupled with the frame member 140. Also, a pair of stationary hand grips 150 may be coupled with the upright frame member 140. While not specifically shown, other components, such as a fan, may also be coupled with the frame member 140 as will be recognized by those of ordinary skill in the art.
The second assembly 104 also includes a first reciprocating arm 152 and second reciprocating arm 154. The first reciprocating arm 152 includes a first end 156 and a second end 158. Similarly, the second reciprocating arm 154 includes a first end 160 and a second end 162. Upper portions of the reciprocating arms 152 and 154 near the first ends 156 and 160 are configured as grips or handles for a user to grasp with their hands while exercising. The second ends 158 and 162 of the reciprocating arms 152 and 154 are pivotally coupled with the first ends 118 and 124 of the foot support members. Each of the reciprocating arms 152 and 154 are pivotally coupled to the frame member 140 through associated pivoting structures 164. The pivoting structures 164 may include, for example, a bearing member that enables the reciprocating arms to pivot back and forth along an axis of rotation 166 in a reciprocating fashion.
During operation of the elliptical machine 100, a user places their feet on the foot pads 122 and 128 and applies a force in order to motivate the foot supports 114 and 116 to move through their defined looping pathways. The pathway of the foot supports 114 and 116 (and thus the foot pads 122 and 128) is defined in part by the connection of the foot supports 114 and 116 with the rear mechanism 112 and in part by the connection of the foot supports 114 and 116 with the reciprocating arms 152 and 154.
In addition to the two assemblies 102 and 104 being connected by way of the pivoting connection of the foot supports 114 and 116 with associated reciprocating arms 152 and 154, the longitudinal frame member 106 is pivotally coupled with the upright frame member 140 by a pivoting structure 170. Again, the pivoting structure 170 may include a bearing component (e.g., a sleeve bearing, a roller bearing, or other appropriate structure) to accommodate pivoting movement of the upright frame member 140 relative to the longitudinal frame member 106. Associated with the pivoting structure 170, a locking or coupling mechanism 172 may be used to affirmatively maintain the frame members 106 and 140 (and, thus, the assemblies 102 and 104) in their operating positions as shown in FIGS. 1 and 2 and as will be described in further detail below.
Referring briefly to FIG. 3, another embodiment of an elliptical exercise machine 180 is shown. The elliptical machine is similar to that shown and described with respect to FIGS. 1 and 2 above, including a first assembly 102, a second assembly 104 and the various components described above. The elliptical machine 180 shown in FIG. 3 further includes an incline adjustment mechanism 182 that enables selective height adjustment of the front cross member 108 relative to the rear cross member 110, thereby altering the angular orientation of the foot supports 114 and 116 and their associated pathways. The incline adjustment mechanism 182 may include, for example, a pair of arms 184 or links (one shown in FIG. 3) pivotally coupled between the front cross member 108 and the longitudinal frame member 106, as well as an actuator 186, such as a jackscrew, a pneumatic cylinder, a stepper motor or other appropriate actuating mechanism.
Referring now to FIG. 4, the elliptical machine 100 is shown in a folded or storage position, wherein the second assembly 104 has been rotated about the pivot structure 170 relative to the first assembly 102 such that the upper portion of the second assembly 104 (e.g., the control panel 142, the hand grips 150) are positioned adjacent the rear portion of the first assembly 102 (e.g., the rear mechanism 112). It is noted that the embodiment described with respect to FIG. 3 is also configured to fold or transition into a collapsed or storage condition in a manner similar to that shown in FIG. 4. In one embodiment, such folding or collapsing of the elliptical machine 180 shown in FIG. 3 may be enabled regardless of the current inclined position of the elliptical machine 180. In another embodiment, the pivoting structure 170 of the elliptical machine 180 may be configured to remain in a locked state until the elliptical machined 180 is in a predefined inclination position (e.g., completely lowered to toward the floor or supporting surface).
Referring briefly to FIG. 5, an enlarged view of the various components of the elliptical machine 100 are shown in a folded or collapsed state. FIG. 5 shows the second assembly 104 rotated about the pivot structure 170 relative to the first assembly 102. It is noted that, when in the position or state shown in FIGS. 4 and 5, the pivotal axes of the connections between foot supports 114 and 116 and associated reciprocating arms 152 and 154 are aligned with the pivotal axis of the pivot structure 170 which couples the longitudinal frame member 106 and the upright frame member 140.
Referring to FIG. 6, a partial cross-sectional view is shown of portions of the first and second assemblies 102 and 104 including a locking or coupling mechanism 172 which is engaged to maintain the first and second assemblies 102 and 104 in their operating positions. In one embodiment, the coupling mechanism 172 may include a fastener 190 having a handle or knob 192 coupled therewith enabling a user to rotate the fastener by hand (i.e., without the need for additional tools). The fastener 190 may be configured to be rotationally coupled with the upright frame member 140 of the second assembly 104. The fastener may be configured to threadably engage a structure or component of the first assembly 102. For example, a post 194 or other structural component may be coupled with the longitudinal frame member 106 and include, for example, a plate 196 through which a threaded aperture is formed. The fastener 190 may then selectively engage and disengage the threaded aperture in order to either maintain the first and second assemblies 102 and 104 in an operating condition (as shown in FIGS. 1, 2, 3 and 6) or to enable relative rotation of the first and second assemblies 102 and 104 so that they may be placed in a stored or collapsed condition (as depicted in FIGS. 4 and 5). While the embodiment shown in FIG. 5 includes a fastener 190 used to affirmatively couple the first assembly 102 and the second assembly 104 in an operating position, other mechanisms and structures may also be used. For example, a locking mechanism with a cam surface may be used to provide an affirmative coupling. Other examples may include locking pins that may be inserted in aligned apertures of different components of the first and second assemblies 102 and 104.
It is noted that the upright arm 140 of the second assembly 104 is configured such that it does not interfere with the post 194 or plate 196 (or other similar structure) when rotating between an operational position and a collapsed position. For example, if the upright arm 140 is formed from structural tubing (e.g., with a square or rectangular cross-section), a portion of the tubing may be removed, as shown in FIG. 6, to provide an opening 198 that enables non-interfering rotation of the upright frame member 140 relative to the post 194 and plate 196.
While not specifically shown, a mechanism or structure may be also be provided to lock the first and second assemblies 102 and 104 in a collapsed position so that, for example, if an individual desires to move the elliptical machine 100 (or 180) while it is in the collapsed position, the first and second assemblies 102 and 104 will maintain their positions relative to each other.
INDUSTRIAL APPLICABILITY
Elliptical exercise machines, while popular for residential use, inherently take up a substantial amount of space in a user's home or apartment. For example, in one embodiment, an elliptical machine may be approximately 24 to 30 inches in width, approximately 76 to 84 inches in length and approximately 62 to 70 inches in height. Some users may not desire to permanently dedicate so much space in their residence to an exercise machine. The elliptical machines described herein provide the ability to place the machine in a collapsed position or state when not in use so that the elliptical machine may be stored or more easily maneuvered and transported.
One of the advantages of the described embodiments above is that the elliptical machine is configured in two assemblies, which may be referred to as an upper assembly and a lower assembly, wherein the upper assembly pivots and folds down on to or adjacent to the lower assembly without the need to disassemble or otherwise any of the operational components such as the foot supports or the reciprocating arms. In various prior art devices, in order to collapse or fold into a storage condition. For example, some prior art devices required a “break-away” joint in the foot supports or the reciprocating arms, such that a user would have to disassemble such joints in order to facilitate the folding or collapsing, and then reassemble such joints when the elliptical machine was unfolded or expanded and prior to using the exercise machine again. Moreover, the present design eliminates the possibility of someone trying to use an elliptical machine prior to reassembly of such components, which could possibly result in damage to the machine or injury to the user.
Similarly, folding or collapsing of the assemblies in the elliptical machines described herein does not require the adjustment of any operative components such as the foot supports or reciprocating arms. For example, as previously noted, PCT Patent Application Publication No. WO2008138124 describes a machine wherein the reciprocating arms require adjustment between the operative condition and the stored condition. The present invention does not require any adjustment of the reciprocating arms or the foot supports to in transitioning from the operable condition to the stored condition. Rather, the components of the first assembly all maintain their operational relationship to one another and all the components of the second assembly maintain their operational relationship to one another before and after the folding or unfolding of the elliptical machine. Such a configuration enables very simple folding and deployment of the elliptical machine by a user since they don't have to adjust any critical components (e.g., foot supports or reciprocating arms) and ensures that the elliptical machine is in a ready immediately after unfolding.
The ability to fold or collapse the elliptical machine further provides advantages in moving or transporting the machine when not in use. Besides taking up less space when in a folded state, the elliptical machine is much easier to handle or transport when in the folder state since it is more compact and its center of gravity is more amenable to lifting and maneuvering making it less likely to tip or fall. Furthermore, the ability to fold and unfold the elliptical machine makes it easier to ship or transport in a small package while not requiring assembly after shipping or purchase by the end user.
