Definitions
- a weight machine exercises the user's muscles by having the user push, pull, or otherwise move an exercise assembly that is connected to a resistance device, such as a stack of weights.
- the exercise machine may include one or more exercise assemblies, each designed to exercise a specific muscle group. Some exercise assemblies may be configured by the user to perform more than one exercise.
- Common weight-lifting exercises include press and pull exercises.
- press and pull exercises the user pushes or pulls a pair of arms connected to a weight stack or other resistance device.
- the arms typically move along a fixed path.
- some manufacturers of strength training equipment have designed and manufactured some exercise machines wherein the arms follow a converging path for pushing exercises and a diverging path for pull exercises.
- Some still design and manufacture exercise machines wherein the arms follow a traditional neutral path. Having to choose which machine to use or to purchase for the consumer has become difficult. This is a drawback for prior press and pull exercise machines.
- the user may want to adjust the path of the arms to perform different exercises. For example, the user may want to perform converging pushing exercises and neutral pulling exercises. Also, the user may want to perform pushing movements using alternate fixed paths or pulling movements using alternate fixed paths to vary the muscles being used. Thus, there is a need for a press and pull exercise machine that enables the user to adjust the travel path of the arms.
- press and pull exercises are typically performed at different machines or at different stations on a multi-station exercise machine. Having multiple machines or stations to perform both press and pull exercise increases the cost of the exercise equipment, as well as the space needed to house the exercise equipment. Thus, it would be desirable to vary an exercise routine by performing alternate fixed path movements for both press and pull exercises at a single station on the same exercise machine.
- the present invention provides a press/pull exercise machine with means to adjust the travel path of the arms.
- the press/pull exercise machine comprises a frame, a pair of arm assemblies pivotally connected to the frame for rotation about a respective first axis to perform exercise, and a resistance device and a connecting assembly operatively connecting the arm assemblies to the resistance device.
- the resistance element comprises a stack of weights connected to the arm assemblies by a cable assembly.
- the connecting assembly may comprise a cable assembly, a link assembly, or a combination cable and link assembly.
- the arm assemblies may comprise a lever arm which may include one or more handles for gripping by user during exercise, an arm member to adjust the angle of the lever arm, and a connection member connected to the arm member to connect resistance.
- each arm assembly is mounted to its own swivel assembly that allows the arm assembly to rotate about a respective second axis to adjust the travel path of the arm assemblies. Rotation of the arm assemblies about the respective second axes changes the travel path of the arm assemblies.
- Each swivel assembly may include a locking mechanism to lock the arm assembly in a fixed position during exercise. The user can adjust the travel path of the arm assembly by unlocking the swivel assembly, rotating the swivel assembly about the second axis to a desired position, and relocking the swivel assembly in the new position.
- Patent application Ser. No. 11/346,528 wherein Roger Batca is the inventor explains how the two swivel assemblies can be linked together wherein adjusting one swivel assembly will adjust the other swivel assembly in the opposite direction.
- a cable assembly connects the arms to a stack of weights.
- the cable assembly includes one or more pulleys pivotally connected to the frame and/or arms so as to self-align when adjustments are made to the travel path of the arms as well as the movement of the arms during exercise.
- a link assembly or combination link and cable assembly connects the arms to a stack of weights.
- the link or link and cable assembly includes one or more pulleys and/or links pivotally connected to the frame and/or arms so as to self-align when adjustments are made to the travel path of the arms as well as the movement of the arms during exercise.
- the arms include first and second sections that are pivotally connected together. The user can adjust the angle between the first and second sections.
- one or more bumpers are included to provide a rest position for the arm assemblies during path adjustments to the arms and when not in use.
- a moveable pulley with at least two axes of rotation is pivotally connected to a respective arm member, and bumpers against a respective guide pulley assembly attached to the frame.
- the guide pulley assembly may be pivotally attached.
- the arm assemblies bumper against a frame member.
- the arm assemblies bumper against a respective swivel assembly. All three embodiments allow the connecting assembly to maintain a substantially constant tension for all travel path adjustments of the arm assemblies.

Description
- This application is being filed as a continuation-in-part (CIP) to U.S. patent application Ser. No. 11/384,958 filed Mar. 20, 2006, which is filed as a continuation-in-part (CIP) to U.S. patent application Ser. No. 11/346,528 filed Feb. 2, 2006, which is filed as a continuation-in-part (CIP) to U.S. patent application Ser. No. 11/254,576 filed Oct. 20, 2005, which is incorporated herein by reference.
- Various types of exercise machines for strengthening and conditioning the body are known. One types of exercise machine, referred to herein as a weight machine, exercises the user's muscles by having the user push, pull, or otherwise move an exercise assembly that is connected to a resistance device, such as a stack of weights. The exercise machine may include one or more exercise assemblies, each designed to exercise a specific muscle group. Some exercise assemblies may be configured by the user to perform more than one exercise.
- Common weight-lifting exercises include press and pull exercises. In press and pull exercises, the user pushes or pulls a pair of arms connected to a weight stack or other resistance device. The arms typically move along a fixed path. In recent years, some manufacturers of strength training equipment have designed and manufactured some exercise machines wherein the arms follow a converging path for pushing exercises and a diverging path for pull exercises. Some still design and manufacture exercise machines wherein the arms follow a traditional neutral path. Having to choose which machine to use or to purchase for the consumer has become difficult. This is a drawback for prior press and pull exercise machines. There are a number of reasons why a person may want alternate fixed travel paths for the arms. First, the user may want to adjust the arms to follow a path that is comfortable for the user. Second, the user may want to adjust the path of the arms to perform different exercises. For example, the user may want to perform converging pushing exercises and neutral pulling exercises. Also, the user may want to perform pushing movements using alternate fixed paths or pulling movements using alternate fixed paths to vary the muscles being used. Thus, there is a need for a press and pull exercise machine that enables the user to adjust the travel path of the arms.
- Another drawback with conventional press and pull exercise machines that offer converging or diverging paths is that press and pull exercises are typically performed at different machines or at different stations on a multi-station exercise machine. Having multiple machines or stations to perform both press and pull exercise increases the cost of the exercise equipment, as well as the space needed to house the exercise equipment. Thus, it would be desirable to vary an exercise routine by performing alternate fixed path movements for both press and pull exercises at a single station on the same exercise machine.
- The present invention provides a press/pull exercise machine with means to adjust the travel path of the arms. The press/pull exercise machine comprises a frame, a pair of arm assemblies pivotally connected to the frame for rotation about a respective first axis to perform exercise, and a resistance device and a connecting assembly operatively connecting the arm assemblies to the resistance device. In one embodiment, the resistance element comprises a stack of weights connected to the arm assemblies by a cable assembly. The connecting assembly may comprise a cable assembly, a link assembly, or a combination cable and link assembly.
- The arm assemblies may comprise a lever arm which may include one or more handles for gripping by user during exercise, an arm member to adjust the angle of the lever arm, and a connection member connected to the arm member to connect resistance.
- The arm assemblies are mounted to the frame in a manner that allows the user to adjust the travel path of each arm assembly. In one exemplary embodiment, each arm assembly is mounted to its own swivel assembly that allows the arm assembly to rotate about a respective second axis to adjust the travel path of the arm assemblies. Rotation of the arm assemblies about the respective second axes changes the travel path of the arm assemblies. Each swivel assembly may include a locking mechanism to lock the arm assembly in a fixed position during exercise. The user can adjust the travel path of the arm assembly by unlocking the swivel assembly, rotating the swivel assembly about the second axis to a desired position, and relocking the swivel assembly in the new position. Patent application Ser. No. 11/346,528 wherein Roger Batca is the inventor explains how the two swivel assemblies can be linked together wherein adjusting one swivel assembly will adjust the other swivel assembly in the opposite direction.
- In another aspect of the invention, in one embodiment, a cable assembly connects the arms to a stack of weights. To accommodate changes in the travel path adjustments and movements of the arm assemblies, the cable assembly includes one or more pulleys pivotally connected to the frame and/or arms so as to self-align when adjustments are made to the travel path of the arms as well as the movement of the arms during exercise. In another embodiment, a link assembly or combination link and cable assembly connects the arms to a stack of weights. To accommodate changes in the travel path adjustments and movements of the arm assemblies, the link or link and cable assembly includes one or more pulleys and/or links pivotally connected to the frame and/or arms so as to self-align when adjustments are made to the travel path of the arms as well as the movement of the arms during exercise.
- In another aspect of the invention, the arms include first and second sections that are pivotally connected together. The user can adjust the angle between the first and second sections.
- In another aspect of the invention, one or more bumpers are included to provide a rest position for the arm assemblies during path adjustments to the arms and when not in use. In one embodiment, a moveable pulley with at least two axes of rotation is pivotally connected to a respective arm member, and bumpers against a respective guide pulley assembly attached to the frame. The guide pulley assembly may be pivotally attached. In another embodiment, the arm assemblies bumper against a frame member. In another embodiment, the arm assemblies bumper against a respective swivel assembly. All three embodiments allow the connecting assembly to maintain a substantially constant tension for all travel path adjustments of the arm assemblies.

weight stack 200 provides resistance to the force applied by the user to theexercise assembly 300. In the exemplary embodiment, theweight stack 200 includes a number ofindividual weight plates 202 that can be selectively added to and removed from the load picked-up by the user to provide variable amounts of resistance.Guide rods 204 extend through apertures in each of theweight plates 202. The bottom ends of theguide rods 204 are secured to thebase 102. The top ends of theguide rods 204 are secured to respective guide post supports 116. Theplates 202 slide vertically along theguide rods 204 as the user exercises. A lifting rod 206 extends through a central opening in theweight plates 202. The lifting rod 206 includes a series of apertures that align withcorresponding apertures 210 in theweight plates 202. The user selects the desired number ofplates 202 to be lifted by inserting apin 212 through theaperture 210 in a selectedplate 202 and engaging thepin 212 with the aperture in the lifting rod 206. Those skilled in the art will appreciate that other resistance devices, such as electronic resistance devices, magnetic breaks, pneumatic cylinders or plate loaded free weights may also be used to practice the present invention. - The
exercise assembly 300 comprises a pair ofarm assemblies 302 that are pushed or pulled by the user to perform exercises. Thearm assemblies 302 are interconnected with theweight stack 200 by thecable assembly 400. Eacharm assembly 302 is pivotally mounted so as to pivot about first and second axes labeled X1 and X2, respectively. Thearm assemblies 302 rotate about axes X1 when the user is exercising. Thearm assemblies 302 rotate about axes X2 to change the travel path of thearm assemblies 302, as will be hereinafter described in further detail. Normally, the adjustment of the travel path is done prior to exercising and the travel path is fixed while exercising. For eacharm assembly 302, the user may select a neutral path, a converging path, or a diverging path. Those skilled in the art will appreciate that the present invention could be used to select multiple converging paths and/or multiple diverging paths. - A
respective arm assembly 302 comprises three main components: aswivel assembly 310, anarm member 330, and alever arm 301. Arespective swivel assembly 310, shown inFIG. 3 , comprises a generally U-shaped mounting bracket 314. Bracket 314 includes mountingholes 316 which are used to pivotally connect thearm member 330 to theswivel assembly 310. The mountingholes 316 lie along the first axis X1. Ashaft 320 extends upward from the bracket 314 along the second axis X2. Theshaft 320 extends upwardly through aligned openings in thecross member 114 and a locking plate 150 to rotatably connect theswivel assembly 310 to theframe 100. Theshaft 320 is secured by acollar 315 so that theentire swivel assembly 310 pivots about the second axis X2. - Locking plate 150 is fixedly connected to the
cross member 114 of theframe 100. Limit pin 322 extends upward from the bracket 314 and is received in aslot 152 in the locking plate 150. The engagement of the limit pin 322 in theslot 152 limits the angular rotation of theswivel assembly 310 as it rotates about the second axis X2. Lockingpin 326 projects upwardly from the bracket 314 and engages one of a series of lockingholes 154 in the locking plate 150. The user can disengage thelocking pin 326 from the lockinghole 154 by pulling downward on the handle. The locking pin 324 is preferably biased to a locked position as shown inFIG. 3 . When the handle is released, the lockingpin 326 re-engages with a selected lockinghole 154 in the locking plate 150. As will be explained below, rotation of theswivel assembly 310 about axis X2 changes the path of travel of thearm 302. - A
respective arm member 330, as shown inFIG. 3 , comprises adjustment arm 332 which is pivotally connected at its upper end to theswivel assembly 310 so as to rotate about the first axis X1.Shaft 356 provides a pivoting mount point with an axis of rotation labeled X3 for thelever arm 301. Anaperture plate 340 is attached to the adjustment arm 332 and provides locking means for thelever arm 301. A shaft (not shown) is attached on the bottom of the adjustment arm 332 and provides a connection point for amoveable pulley 440 and is labeled with an axis of rotation R1. - A
respective lever arm 301 includes one ormore handles 355, as shown onFIG. 2 , at the lower end thereof that is gripped by the user. Thelever arm 301 is pivotally connected to the adjustment arm 332 and is rotatable about axis X3. As shown inFIG. 1 ,collar 346 secureslever arm 301 to adjustment arm 332. The angle of thelever arm 301 relative to arm 332 can be adjusted by disengaging the locking pin 345,rotating lever arm 301 to the desired position, and re-engaging the locking pin 345 with one of theapertures 342 in theaperture plate 340. This will provide the user various positions for pressing or pulling exercises. As mentioned earlier, the user can adjust the path thearm assemblies 302 will travel by rotating theswivel assemblies 310 and locking them into the desired position. This will in turn rotate thelever arms 301 about axes X2 and provide the user with various paths of travel. A connection member is needed to rotate along with the arm member 332 when travel path adjustments are made in order to align with the connecting assembly and will be discussed further below. - The
cable assembly 400 interconnects thearms 302 of theexercise assembly 300 with theweight stack 200 so that when either one of thearms 302 are pushed or pulled outward by the user during exercise, theweight stack 200 is lifted. Anexemplary cable assembly 400 is described below. Those skilled in the art will appreciate that a similar result could be achieved using a different configuration of pulleys and cables. Also, belts, chains, and rods with universal ends could be used instead of cables to connectexercise assembly 300 to theweight stack 200. - The
exemplary cable assembly 400 includes first andsecond cables first cable 402 connects to theweight stack 200. Thesecond cable 404 connects to thearms 302 of theexercise assembly 300. Thecable assembly 400 further includes a double floatingpulley assembly 410 interconnecting thecables guide pulley assemblies 420 pivotally connected to theframe 100 and are labeled 182, a pair ofmovable pulley assemblies 440 mounted torespective arms 302, and fixedpulleys frame 100. Theguide pulley assemblies 420 have respective axes of rotation labeled S1. In an alternate embodiment, theguide pulley assemblies 420 are fixedly attached to theframe 100 and are labeled 185. As shown inFIGS. 3 and 5 ,bumpers 481 are attached to swiveling guide pulleymain assembly 182 and to fixed guide pulleymain assembly 185 and will be discussed in more detail further below. - The
moveable pulley assemblies 440, shown inFIGS. 3 and 5 , includes arespective pulley 442 andrespective bumper 482 on one end, and a respective ball joint 483, with at least two axes rotation, on the other end. The ball joints 483 are attached to the lower end of respective arm members 332, secured by collars 484, and are labeled with axes of rotation labeled R1. Those skilled in the art will appreciate that ball joints have more than one axis of rotation. Themoveable pulley assemblies 440 rotate to maintain cable alignment with thecable 404 when the travel paths of thearm assemblies 302 are adjusted and during movement of thearm assemblies 302. Themoveable pulley assemblies 440 and the swiveling guide pulleymain assembly 182, shown inFIGS. 1 and 2 , bumper one another and provide a rest position for thearm assemblies 302. Themoveable pulley assemblies 440 rotate about at the ball joints 483 thus enabling thecable assembly 400 to maintain a substantially constant tension. Themoveable pulley assemblies 440 and the fixed guide pulleymain assembly 182, shown inFIG. 4 , bumper one another and provide a rest position for thearm assemblies 302. Themoveable pulley assemblies 440 rotate about at the ball joints 483 thus enabling thecable assembly 400 to maintain a substantially constant tension. -
Cable 402 is connected at one end to the lift rod 206 and at the opposite end to thebase 102.Cable 402 passes around fixedpulleys pulley assembly 410. While thecable 402 is depicted as being anchored to thebase 102, those skilled in the art will appreciate that thecable 402 could also be connected to another exercise assembly.Cable 404 passes around floating pulley 414 of the floatingpulley assembly 410, fixedpulleys pulleys 442 of themoveable pulley assemblies 440, and guide pulleys 422. Those skilled in the art will appreciate that the ends of thecable 404 could also be connected to other exercise assemblies. - In use, the user adjusts the angle of the
lever arms 301 to a comfortable position depending on factors such as the user's arm length, flexibility and the exercise chosen. The user also adjusts the travel path for eacharm assembly 302 by rotating eacharm assembly 302 about the second axis X2 to a desired position. For eacharm assembly 302, the user can select a neutral path, converging path, or diverging path. Those skilled in the art will appreciate that some embodiments may provide for multiple converging and diverging paths. After the adjustments are made, the user sits onseat 130 with the user's back or chest against the seat back 145. The user grasps thehandles 355 for eacharm assembly 302 and pushes or pulls thearm assemblies 302 outward to lift theweight stack 200. During exercise, thearm assemblies 302 rotate about the first axis X1. Eacharm assembly 302 will follow either a neutral path, converging path, or diverging path as selected by the user. Themoveable assemblies 440 connected to thearm assemblies 302 will rotate to self-align with thecable 404 when the travel path of thearm assemblies 302 is adjusted and during movement of thearm assemblies 302. The user may choose to use the arms independently one at a time for some exercises. -
