Embodiments of the present invention relate to manually operated exercise equipment and more specifically, to methods and apparatus for accommodating a person in a standing position and performing exercises by pulling at least one cord from an associated sheave.
A variety of exercise devices have been developed to resist exercise motion. Examples are disclosed in U.S. Pat. Nos. 6,726,607 and 7,087,001 to Ihli, U.S. Pat. Nos. 8,465,410, 8,523,745, 8,556,783, 8,556,785, and 8,622,879 to Ihli et al., and U.S. Patent Publication Nos. 20180021617 and 20180280753 in the name of Ihli et al., An object of the present invention is to provide improved exercise devices and methods of using same.
One aspect of the present invention involves an exercise resistance device having a cord that is wrapped about a sheave. The cord is extracted from the sheave in response to an externally-supplied user force, and rewound onto the sheave when an internally-supplied spring force exceeds the user force. In one embodiment, left and right sheaves rotate about a fixed axis as corresponding left and right cords are pulled from the sheaves and subsequently allowed to rewind onto the sheaves. The cords are preferably routed through swiveling pulleys that swivel about respective axes that align with respective cords. The swivel pulleys are preferably disposed between the resistance device and a foot platform. A handlebar is preferably provided above the location of the resistance device so a person can brace herself with one or both hands while performing exercises (via the cords) with one or both legs. A holder is preferably mounted on the handlebar to hold one or both cords at a relatively higher elevation above the floor surface when not in use, allowing a person to readily grab the cords and perform exercises with one or both arms (via the cords) without bending over to take hold of the cords proximate the swivel pulleys.
Various features and/or advantages of the present invention will become apparent from the more detailed description that follows.
With reference to the Figures of the Drawings, wherein like numerals represent like parts and assemblies throughout the several views:
An embodiment exercise apparatus constructed according to the principles of the present invention is designated as 100 in
The exercise apparatus 100 includes a frame or base 110 configured to occupy a stable operating position on an underlying horizontal floor surface F. The base 110 is constructed in a manner known in the art and preferably comprises square steel tubes and sheet metal brackets that are welded together to form a rigid frame 100 extending from a first or front end 112 to an opposite, second or rear end 114. Plastic shell members cooperate to form an enclosure or shroud 101 about the resistance device 200 and most of the base 110, and are secured to the base 110 be screws or other known means.
Since the resistance device 200 is known in the art, it will be described in only general terms with the understanding that additional details may be gleaned from the documents incorporated herein by reference. The resistance device 200 includes a shaft 210 rotatably mounted on the frame 110; a brake drum 220 keyed to the shaft 210; an adjustable brake assembly 230 mounted on the frame 110 and operatively connected to the brake drum 220, including a respective user-operated adjustment knob 232; a right sheave 240 and associated rewind spring, wherein the right sheave 240 is connected to the shaft 210 by a one-way clutch bearing, and the rewind spring (not shown) is interconnected between the frame 110 and the right sheave 240; and a mirror image left sheave (not shown) and associated rewind spring, wherein the left sheave is connected to the shaft 210 by a one-way clutch bearing, and the rewind spring (also not shown) is interconnected between the frame 110 and the left sheave.
A left cord 252 has a first end connected to the left sheave, an opposite second end connected to a carabiner 99 for attachment to a force receiving member (as further discussed below and in the incorporated references), and intermediate portions disposed therebetween, including a portion wrapped around the left sheave. Similarly, a right cord 242 has a first end connected to the right sheave 240, an opposite second end connected to a carabiner 99 for attachment to a force receiving member (as further discussed below and in the incorporated references), and intermediate portions disposed therebetween, including a portion wrapped around the right sheave 240. For ease of illustration,
The frame 110 includes a central tube or channel member 116 that extends longitudinally front to back and defines the rear end 114 of the frame 110. At least one front leg or tube is connected to a forward end of the central frame member 116 to define laterally extending left and right front leg segments. Floor engaging feet 98 of a type known in the art are secured to distal ends of the left and right front leg segments to engage an underlying horizontal floor surface F. Another foot 98 is secured to the center of the central frame member 116 proximate the rear end 114 to similarly engage the underlying horizontal floor surface F.
Proximate the rear end 114 of the frame 110, right and left tubes or arm members 124 and 125 extend laterally outward from respective sides of the frame. Left and right brackets 140 and 150 are rotatably mounted on respective members 124 and 125 for rotation about parallel respective bracket axes X. Right and left pulleys 142 and 152 are rotatably mounted on respective brackets 140 and 150 for rotation about respective pulley axes, which extend perpendicular to respective bracket axes X. Each cord 242 and 252 has an intermediate segment routed from a respective sheave to a respective pulley 142 or 152, and each such cord segment linearly aligns with a respective bracket axis X. As a result, each pulley 142 and 152 can pivot to the left or to the right without disrupting smooth and reliable passage and re-routing of a respective cord 242 or 252. Recognizing that the orientation of the cord segment will vary to an extent based on how much cord is wrapped around the sheave, it may be said that at some point between minimum extraction and maximum extraction, the cord segment linearly aligns with the bracket axis X, and/or the cord segment remains within five degrees of being co-linear with the bracket axis X throughout the range from minimum extraction to maximum extraction.
Each pulley 142 and 152 may be described as being positioned forward of the foot platform 160 and/or rearward of a respective sheave. Each pulley 142 and 152 also may be described as being positioned relatively higher than the foot platform 160 and/or relatively lower than the shaft 210 of the resistance device 200.
A foot support 160 is selectively and adjustably connected to the frame 110. In this regard, a foot support member or connector 162 has a forward end that telescopes into the central frame member 116. A fastener 96 of a type known in the art extends through a hole in the central frame member 116 and an aligned one of several holes 164 in the foot connector member 162. An opposite, rear end of the foot connector member 162 is rigidly secured to a plastic foot platform 166, both directly and via a metal framework of reinforcement members. The foot platform 166 defines a textured, upwardly facing foot supporting surface that is sized and configured to receive and support both feet of a person in a standing position. Consistent with the feet 98, the foot support 160 is configured to occupy a stable operating position relative to the underlying floor surface F. For storage and/or transportation purposes, the foot connector member 162 may be pulled out of the central frame member 116 to free the foot support 160 from the base 110, thereby significantly decreasing the footprint of the apparatus 100, as shown in
A front post or frame member 118 is rigidly connected to a forward end of the central frame member 116. Within the confines of the housing 101, the post 118 extends primarily upward away from the floor surface F to support a handlebar 170.
As shown in
Two threaded holes extend into the bar 176, one of which is designated as 177 in
Like much of the apparatus 100, the handlebar 170 is preferably symmetrical about a vertical plane extending through the center of the bar 176 (and the center of the post 118). The handlebar includes left and right substantially horizontal handlebar segments or cylindrical tubes 173, which are disposed at a higher, doubled elevation than the segments 172, and which extend perpendicular to the segments 172. Substantially vertical left and right handlebar segments or cylindrical tubes 173 are integrally interconnected between respective segments 173 and 172 via arcuate transition members or curved cylindrical tubes (shown but not numbered). The term “substantially” shall be interpreted to mean within 20 degrees of the referenced attribute (as in within 20 degrees of vertical or within 20 degrees of horizontal).
The handlebar 170 includes a centrally located horizontal segment 175 that is integrally interconnected between proximate ends of respective segments 173 via arcuate transition members or curved cylindrical tubes (shown but not numbered). As a result, the handlebar 170 cooperates with the bar 176 to formed a closed loop curve.
A console 180 is rigidly secured to the middle of the handlebar segment 175. The console is an assembly of injection molded plastic pieces sized and configured to hold various items. For example, the console 180 defines a recess 182 wherein a person can set a booklet or a cell phone. Also, the console 180 defines right and left notches or openings 184 and 185 to accommodate respective left and right cords 242 and 252 and hold in place respective carabiners 99. As shown in
The housing 101 includes a member 103 that defines a centrally located upwardly opening window. The member 103 overlies part of a large disc 130, and aligns with numbers disposed on the disc 130. With reference to
In use, a person stands with at least one foot on the foot platform 160 and pulls at least one carabiner 99 away from a respective pulley 142 or 152. The carabiner 99 may be considered a force receiving member, but preferably is clipped to a more suitable force receiving member, examples of which are known in the art and/or disclosed in the incorporated references. The person may perform some exercises with her toes pointed toward the console 180, others with her toes pointed in an opposite direction, away from the console 180, and others with her toes facing left or right. In some instances, especially when exercising a single arm and/or a single leg, the person may brace herself by grasping some portion(s) of the handlebar 170 in one or both hands. The person may reposition the foot platform 160 relative to the base 110 by loosening the fastener 96, sliding more or less of the connector 162 into the central frame member 116, and tightening the fastener 96 with holes in the connector 162 and the central frame member 116 aligned. The person may adjust resistance to exercise by rotating the knob 232 clockwise to increase resistance or counter-clockwise to decrease resistance. The person may choose to adjust until a particular number appears in the window member 103 or until the resistance feels appropriate. The person may elect to place her cell phone on the console to provide entertainment and/or exercise information during exercise. The person may elect to temporarily store one or both carabiners 99 on the console 180 to place them within reach while standing upright on the foot platform 160.
