This invention relates, generally, to exercise equipment. More specifically, it relates to a pushup exercise device that allows a user to perform pushups with added resistance safely.
Pushups have always been used to measure one's body strength and are beneficial to people of all ages. Many people do bodyweight exercises such as pushups along with weightlifting exercises in their workouts. However, people have the need to add resistance to pushups in a safe and convenient manner to match the intensity of their weightlifting exercises within the timeframe of their workouts. People do pushups with added resistance for two reasons: 1) keep doing pushups with added intensity, and 2) improve bench press performance.
There are many pre-existing methods for adding resistance to pushups; however, the pre-existing methods have significant drawbacks, including major safety concerns. For example, the most common approach in commercial gyms includes placing weight plates on the exerciser's back or wearing a weight vest. The exerciser typically engages the help of a partner to put the weight plate on their back and take the weight off when the set of pushups is complete.
In U.S. Pat. No. 7,588,521 to Carlo Fazzari (2009), one does pushups with weights placed on a weight support platform placed on one's back, and as pushups are repeated, the weight support platform with parallel upright rods slide up and down along parallel guide elements.
In U.S. Pat. No. 9,511,258 to Richard J. Hoole (2016) a user performs weighted pushups by grasping on a pair of hand grips that are above a lever arm and feet are placed on an elevated platform that is adjustable in height relative to the pair of handgrips. The lever arm has a proximate end coupled pivotally to a base, and the lever arm is configured to provide resistance against vertical movement of a distal end of the lever arm. The distal end of the lever arm is configured to receive a connector suspended from a belt or harness worn by a user.
In U.S. Pat. No. 5,033,741 to Ganzer (1991) a wall-mounted isometric pushup machine allows a user to perform pushups against a padded base that provides resistance in the vertical direction using pressure springs. The user can adjust the amount of resistance by changing the pressure spring.
Few people in commercial gyms use chains to add resistance to pushups by laying it over their back, forming an X-shape. Another way people add resistance to pushups is by using resistance bands. Some use clip bands/flat bands/strength bands to loop it over their backs and place their hands on the band and do pushups. For example, in U.S. Pat. No. 6,244,998 to Jon Harrington Hinds (2001), pushups with added resistance are performed by placing a padded cushion on one's back, and resistance bands are attached to it and to soft handles at the other end. In U.S. Pat. No. 9,205,299 to Raashed Hall (2015) a kind of resistance band known as a flat band is looped around one's back and attached to hand grips to add resistance to pushups. In U.S. Pat. No. 9,155,934 to Blake Kassel (2015) a user performs pushups with added resistance using a resistance band known as clip band that loops around one's back and attached to hand grips.
In U.S. Patent Application Publication 20040242388 to Richard Kusminsky (2004) a user performs pushups with added resistance by using a unidirectional exercise machine for increasing the effort required for a user to perform a pushup or other exercise, including an adjustable brake engaging a cable drum for inhibiting the unwinding of a cable attached to a user during the extending portion of the exercise and a clutch operatively coupled to the brake for releasing the brake and allowing the cable to freely rewind during the retracting portion of the exercise.
In U.S. Patent Application Publication 20140274593 to Sean Kelly (2014), a user performs pushups with added resistance by using a resistance pushup apparatus, having a harness to be worn by a user, and having hooks to attach the harness to a set of free weights. The pushup apparatus allows the user to lift their own weight plus the extra free weights connected to the harness during the pushup exercise.
However, it is not safe to put a lot of weight plates on your back and do pushups even in the presence of a partner. In the case of wearing a weight vest, it is not safe to wear a heavyweight vest when doing pushups and reaching near failure. It is difficult to get out of a set of pushups when using a weight vest. The use of chains is not practiced at most commercial gyms and is inconvenient. For Fazzari's disclosure, it is difficult to get out of the prone (starting) position when done performing finger pushups as the weight is still on the user or the weight support platform is right above the user. For Hoole's disclosure, one cannot perform pushups such as finger pushups and knuckle (punch/fist) pushups with added resistance. For Hind's disclosure, one cannot perform finger pushups and knuckle pushups as well as pushups with different hand grips with added resistance. It causes pain in the hands and wrists when using heavy resistance bands because the soft handles loop around the thumbs. For Hall's disclosure, one cannot perform finger pushups and knuckle pushups as well as pushups with different hand spacing with added resistance. Also, one is limited by the amount of resistance they can use since only one flat band is used and other kinds of bands cannot be used. For Kassel's disclosure, one cannot perform finger pushups, knuckle (punch/fist) pushups, and pushups with different hand spacing with added resistance. The resistance band may move or slide when one reaches the starting position of a pushup. For Kusminsky's disclosure, one cannot perform finger pushups and knuckle pushups as well as pushups with different hand grips with added resistance. For Kelly's disclosure, it requires one to set up and create space for those who train in commercial gyms. Even if commercial gym members use two benches to execute pushups with added resistance, the benches are usually occupied by other gym members doing other exercises either by the dumbbell rack or in power racks/smith machines. Those interested in doing partial push-ups (the last few inches before the end position of a pushup) and isometric pushups (static contraction) would have to set up and cannot easily do that in commercial gyms.
These disclosures heretofore known suffer from a few disadvantages:
1. One cannot perform various pushup exercises such as finger pushups, knuckle (punch/fist) pushups, pushups with different hand grips, planks, and pushup to row (A.K.A. pushup renegade row) with added resistance to failure independently in a safe and convenient manner along with other exercises in a workout without sacrificing valuable time for productive muscle building with time spent on setting up which most people do not have especially commercial gym members.
2. One cannot perform various pushup exercises such as finger pushups, knuckle push-ups, pushups with different hand grips, planks, and pushups to row with added resistance all in one machine.
Accordingly, what is needed is an improved exercise machine that allows an exerciser to perform a variety of pushups with added resistance in a safe manner. However, in view of the art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the field of this invention how the shortcomings of the prior art could be overcome.

The long-standing but heretofore unfulfilled need for an improved pushup exercise device that allows an exerciser to perform a variety of pushups with added resistance in a safe manner is now met by a new, useful, and nonobvious invention.
An embodiment of the present invention is a pushup exercise device including a graspable member having a first end, a second end, and a body extending between the first end and the second end of the graspable member. At least a portion of the body of the graspable member has a graspable portion. A base platform is in mechanical communication with the graspable member and includes a flat bottom end configured to engage with a surface. The present invention further includes an attachment component in mechanical communication with a graspable member and an unobstructed passage. The unobstructed passage provides a route through which a cable can attach to the attachment component, thereby allowing the user to perform exercises with the pushup exercise device by grasping the graspable portion of the graspable member.
In an embodiment, the pushup exercise device further includes an upstanding support member having a first end coupled with the base platform and a second end coupled with a first portion of the body of the graspable member. Furthermore, the pushup exercise device may include an open region defined by the graspable member and the surface. The open region is configured to receive the user's fingers when the user grasps the graspable portion of the graspable member.
In some embodiments, a second base platform is provided in mechanical communication with the graspable member. The second base platform includes a flat bottom end configured to engage with the surface and is spaced apart from the first base platform. Furthermore, in such embodiments, a second upstanding support member is also provided, having a first end coupled with the second base platform and a second end coupled with the second portion of the body of the graspable member.
In yet another embodiment, a longitudinal member includes a first end and a second end. The first end of the longitudinal member is coupled to the first upstanding support member and the second end of the longitudinal member is coupled to the second upstanding support member. The attachment component is coupled to at least a portion of the longitudinal member in such embodiments, thereby operably coupling the user at one end and the resistance object.
In an embodiment, the open region is defined by the graspable member, a first base platform, a first upstanding support member, a second base platform, and a second upstanding support member.
Some embodiments include a second attachment component disposed between the first attachment component and the pushup exercise device, such that the second attachment component is mechanically coupled with both the first attachment component and the pushup exercise device.
In an embodiment, the base platform resides within a first plane, and the graspable member resides within a second plane, such that the first plane is parallel to the second plane.
In yet another embodiment, the first portion and the second portion of the body of the graspable member are different.
Some embodiment includes a longitudinal member residing within a third plane. In such embodiments, the longitudinal member is spaced apart from the graspable member, such that the third plane and the second plane of the graspable member and the third plane of the longitudinal member are parallel.
Furthermore, an embodiment of the invention provides a method for performing an exercise. The method provides a cable configured to add resistance to a user or the pushup exercise device described above when the cable is operably connected thereto. A pushup exercise device is provided, including the limitations discussed above. Furthermore, the cable is then passed through the unobstructed passage in the pushup exercise device and is coupled with the attachment component. Lastly, the exercise is performed by the user while operably engaging the pushup exercise device. In an embodiment, a second pushup exercise device is provided, such that the exercise is performed while grasping both the first and the second pushup exercise devices.
An embodiment of the present invention is an exercise device for generally performing resisted pushup exercises. The device includes a housing containing a plurality of resistance members and a cable in operable communication with one or more of the plurality of resistance members, such that forcible movement of the cable imparts a force onto the one or more resistance members in operable communication with the cable. A first attachment component is also in operable communication with the cable and is configured to engage a user-interactable device. The present invention further includes a horizontal platform having a top surface, a bottom surface, and a passage extending through the top surface towards the bottom surface. The passage is sized to house the attachment component in operable communication with the cable when the exercise device is not in use by a user.
The first attachment component further includes a position of repose when not subject to an external force applied by the user. The position of repose includes the first attachment component residing below the top surface of the platform and being unable to exit the cable passage without an external force overcoming a resistance force of the one or more resistance members in operable communication with the cable. As a result, the user can reach a full pushup flexion position with the user's chest on the top surface of the platform while the first attachment component remains subject to the resistance force of the one or more resistance members.
Some embodiments include at least one pulley to guide the cable from the housing to the passage in the platform. In some embodiments, an exit pulley is located adjacent to the passage in the platform below the top surface of the platform. The exit pulley is configured to guide the cable from a horizontal orientation prior to the passage in the platform to a vertical orientation at the passage. Thus, the user can pull the cable vertically while executing a pushup.
In some embodiments, the passage in the platform is located at a position in the platform in which there are no permanent structures preventing a user from performing pushups with the user's hands on the top surface of the platform and chest in overlying relation to the passage.
In some embodiments, the resistance members are weights adapted to move within the housing when subject to an external force.
In some embodiments, the first attachment component is a cable thimble. Some embodiments further include an upper body harness having a second attachment component configured to mechanically engage the first attachment component. In some embodiments, the passage is sized to receive both the first and second attachment components. Thus, the passage can receive the first and second attachment components below the top surface of the platform when the user reaches a full pushup flexion position with the user's chest adjacent to the top surface of the platform.
Some embodiments further include a partial spherical balancing device having a generally centrally located aperture in a curved outer surface sized to receive at least a portion of the cable. Some embodiments further include a pushup bar having a second attachment component configured to mechanically engage the first attachment component.
Some embodiments further include a hinge residing between the platform and the housing containing the plurality of resistance members, thereby enabling the platform to fold upward into a vertical orientation. In addition, some embodiments include a pulley located adjacent to the rotational axis of the hinge that permits the platform to fold upward into a storage orientation without compromising the integrity of the cable.
An embodiment of the present invention includes an exercise device for performing resisted pushup exercises, comprising a housing containing a plurality of resistance members; a cable in operable communication with one or more of the plurality of resistance members, such that forcible movement of the cable imparts a force onto the one or more resistance members in operable communication with the cable; a first attachment component in operable communication with the cable; a second attachment component configured to engage the first attachment component and a user-interactable device; and a horizontal platform having a top surface, a bottom surface, and a passage extending through the top surface towards the bottom surface with the passage sized to receive both the first and second attachment components. Thus, the passage can receive the first and second attachment components below the top surface of the platform when the user reaches a full pushup flexion position with the user's chest adjacent to the top surface of the platform.
Some embodiments include a pulley located adjacent to the passage in the platform and below the top surface of the platform. The pulley is configured to guide the cable from a horizontal orientation prior to the passage in the platform to a vertical orientation at the passage, thereby allowing the user to pull the cable vertically while executing a pushup.
In some embodiments, the passage in the platform is located at a position in the platform in which there are no permanent structures preventing a user from performing pushups with the user's hands on the top surface of the platform and chest in overlying relation to the passage.
In some embodiments, the resistance members are weights adapted to move within the housing when subject to an external force.
In some embodiments, the user-interactable device is a push-bar. In some embodiments, the user-interactable device is an upper body harness.
Some embodiments include a partial spherical balancing device having a generally centrally located through hole sized to receive the cable.
Some embodiments include a hinge residing between the platform and the housing containing the plurality of resistance members. The hinge enables the platform to fold upward into a vertical orientation for storage.
An embodiment of the present invention includes an exercise device for performing resisted pushup exercises, comprising a housing containing a weight stack, wherein in the weight stack includes a plurality of weights adapted to move within the housing when subject to an external force. The invention further includes a cable having a first end and a second end with the first end in operable communication with one or more weights in the weight stack, such that tension imparted on the cable acts as the external force to move the plurality of weights. A first attachment component is in operable communication with the second end of the cable and an upper body harness has a second attachment component configured to mechanically engage the first attachment component. The present invention further includes a horizontal platform having a top surface, a bottom surface, and a passage extending through the top surface towards the bottom surface. The passage is sized to receive both the first and second attachment components. The cable extends from the housing to the passage and passing underneath the top surface of the platform. Moreover, the passage is sized to receive the first and second attachment components below the top surface of the platform when the user reaches a full pushup flexion position with the user's chest adjacent to the top surface of the platform. Furthermore, the second end of the cable and the first and second attachment components are configured to exit the passage through the top surface of the platform when the user is wearing the harness and reaches a full pushup extension position.
Accordingly, several advantages of one or more aspects are as follows: to provide a maximum pushup exercise machine that enables a user wearing a belt or harness to perform pushups (regular, finger, and knuckle) with added resistance and to quickly change the resistance level independently, that enables a user to perform planks and pushup to row exercises with added resistance, and that enables a user to perform pushups on balance and stabilization ball device with added resistance. These advantages will be apparent from a consideration of the drawings and ensuing descriptions.
These and other important objects, advantages, and features of the invention will become clear as this disclosure proceeds.

Referring now to
The exemplary depicted housing 102 houses resistance members 136 in the form of a cable-pulley weight stack system 104. Cable-pulley weight stack system 104 includes a plurality of weights that can be individually selected to modify the amount of resistance. The selection is accomplished through weight stack selector pin 114, which is inserted into weight stack 136. In some embodiments, resistance members 136 are in the form of elastic resistance bands. However, resistance bands have a linear resistance profile in comparison to weights. Thus, weights may be preferable in certain situations. Alternatively, the linear resistance profile may be preferable in certain other situations.
The cable-pulley weight stack system includes cable 120 having first end 121 in mechanical communication with resistance members 136 and second end 123 integrated with or in mechanical communication with first attachment component 110. The cable-pulley weight stack system may include any belts, cables, cams, pulleys, or any combination thereof to enable the operation of the cable-pulley weight stack system.
As depicted best in
Cable 120 is routed from first end 121 through several pulleys to its second end 123. In the depicted embodiment, cable 120 extends to pulley 111, which directs cable 120 horizontally to pulley 113, which redirects cable 120 vertically. Cable 120 then extends to pulley 115, which directs cable 120 to pulley 117 adjacent to the rotational axis of hinge 112. Cable 120 continues to pulley 122, which directs cable 120 under top surface 108a of platform 108. Finally, cable 120 encounters exit pulley 119, which directs cable 120 in a generally vertical direction through passage 109 in platform 108.
As shown in
Second end 123 of cable 120 is integrated with or attachable to first attachment component 110. The figures provide an exemplary form of first attachment component 110 in the form of a cable thimble. Cable thimble 110 passes through passage 109 and can connect to a user-interactable device such as upper body harness 146 having a second attachment component such as a clip, pushup bars 138 having a second attachment component in the form of pushup bar cable connector 140, or single cable handle attachment 148 having a second attachment component. In an embodiment, first attachment component 110 is a cable thimble configured to receive second attachment component, in the form of a snap link hook suspended from harness 146 or a belt worn by user 106.
In some embodiments, second end 123 of cable 120 is configured to become subject to tension from the connection to the resistance members prior to second end 123 exiting passage 109 through upper surface 108a of platform 108. Thus, a user can perform a pushup to maximum flexion (i.e., till the user's chest touches the top surface 108a) while subject to resistance.
In some embodiments, first attachment component 110 attached to cable 120, similar to second end 123 of cable 120, is configured to be under tension below the upper surface 108a of platform 108. Thus, a user can perform a pushup to maximum flexion (i.e., till the user's chest touches the top surface 108a) while subject to resistance.
Platform 108 can be bolted, welded, hingedly connected, or connected in any manner to housing 102 containing a plurality of resistance members.
As explained previously, platform 108 includes a passage 109 extending through top surface 108a to at least cable channel 125. Some embodiments include passage 109, extending completely through platform 108.
In some embodiments, passage 109 is sized to receive first attachment component 110 and a second attachment component, such as a clip, secured to harness 146. As a result, the user can perform a pushup to maximum flexion (i.e., till the user's chest touches the top surface 108a) without the attachment components preventing the user from touching his/her chest to top surface 108a of platform 108.
In some embodiments, passage 109 is centrally located at substantially the midpoint of platform 108. In addition, the configuration of the pulleys ensures that cable thimble 110 is positioned to exit passage 109 in platform 108 in a generally vertical direction.
In some embodiments, passage 109 is positioned at a location in platform 108 to ensure that there are no permanent structural components that would impede a user's ability to perform various pushup exercises. In some embodiments, passage 109 is located at a position in platform 108 in which there are no permanent structures preventing a user from performing pushups with the user's hands on top surface 108a of platform 108 and chest in overlying relation to passage 109.
Some embodiments include chain 150 having a snap link hook suspended from the harness or belt 146 that the user can adjust the length of chain 150 to any link and connect the snap link hook to cable thimble 110.
Some embodiments include housing 102 having container 116 to hold items such as towels, cleaning agent spray bottle, water bottle, etc.
The material of the cable-pulley weight stack system housing may be made of stainless steel or any other material known in the art. The material of the platform may be made of stainless steel covered with rubber like material such as rubber molded handle grips used in exercise handles, particleboard/plywood covered with rubber horse stall mats like a weight lifting platform, any combination thereof, or any material known in the art.
Some embodiments further include partial spherical balancing device 142 having a generally centrally located aperture 144 in a curved outer surface sized to receive at least a portion of cable 120. In some embodiments, aperture 144 is a through-hole sized to receive cable 120, first attachment component 110, and/or chain 150. Partial spherical balancing device 142 allows a user to engage in resisted pushups on an unstable platform. In some embodiments, the balancing device is a fully spherical shape with a through-hole passing through the device.
Some embodiments further include pushup bars 138 having second attachment component 140 configured to mechanically engage the first attachment component. Thus, one of the pushup bars 138 can be attached to cable 120 via second attachment component 140, and user 106 can perform a pushup into a resisted row. Pushup bar 138 includes graspable member 139 located on an upper portion of pushup bar 138. Pushup bar 138 further includes upstanding support members 145 extending from base platforms to graspable memeber 139. Base platforms 141 include a flat bottom end configured to engage with a surface. In addition, attachment component 140 resides between base platforms 141 on an underside portion of pushup bar 138 at a general middle point between the two ends of pushup bar 138. The space between base platforms 141 establishes a channel through which cable 120 can pass to mechanically engage attachment component 140. Some embodiments include a longitudinal member 143 to which attachment component 140 is secured. Longitudinal member 143 extends between the two ends of pushup bar 138 and is downwardly spaced from graspable member 139 to allow a user's fingers to pass between graspable member 139 and longitudinal member 143.
Operation (
A user performs a pushup exercise with added resistance by first selecting a desired weight by inserting weight stack selector pin 114 into weight stack 136. Then, user 106 wears a harness or belt adjusting the length of the chain to any link and leans forward on platform 108, and attaches a snap link hook suspended from a belt or harness to cable thimble 110. In some embodiments, user 106 wears a harness or belt 146 with chain 150 having a snap link hook suspended from harness or belt 146 that the user can adjust the chain's length to any link and connect the snap link hook to cable thimble 110.
Then, user 106 gets into the starting (prone) position of a pushup exercise with their hands on platform 108, as shown in
User 106 can also place their feet on a step-up exercise platform, swiss ball, medicine ball, or any other object to elevate their feet and change their body's angle. In some embodiments, user 106 can attach the snap link hook to any link of chain 150 to allow for partial range of motion pushup exercises. This allows a user to add more resistance to pushup exercises. User 106 can also attach the snap link hook to any link of the chain to execute timed pushup holds (e.g., planks); isometric pushup. This enables a user to perform both yielding and overcoming isometric pushup exercises with added resistance. Yielding isometric pushup exercise would be a user holding a position a few inches before the end position of a pushup for as long as possible even though they can push harder and raise their body. In contrast, overcoming isometric pushup exercise would be a user holding a position a few inches before the end position of a pushup and pushing as hard as possible against an immovable resistance.
User 106 can perform planks, knuckle (punch/fist) pushup, and finger pushups with added resistance using a belt or harness as shown in
User 106 can perform pushup to row (pushup renegade row) exercise with one hand on platform 108 and other hand using a single cable handle attachment 148 that connects to cable thimble 110 to overcome the weight selected from weight stack 136 of the cable-pulley weight stack system 104 as shown in
A user 106 can also perform pushup to row exercise using pushup bar 138 with pushup bar cable connector 140 as shown in
Another exercise user 106 can perform is pushup exercise with his/her hands on balance and stabilization ball device 142 having a balance and stabilization ball device opening 144 with convex side on platform 108 by wearing harness or belt 146 with chain 150 having snap link hook suspended from harness or belt 146 configured to connect to cable thimble 110 through the balance and stabilization ball device opening 144 to overcome the weight selected from weight stack 136 of cable-pulley weight stack system 104 as shown in
The balance and stabilization ball device may be made of a wooden material with comfort anti-slip grip surface on the flat side of it, high density expanded polypropylene (EPP) foam like foam rollers, or any material known in the art that will withstand a user's weight plus the weight of the weight stack.
Advantages
From the description above, several advantages of the maximum pushup exercise machine become evident:
Accordingly, the maximum pushup machine allows a user to perform pushups using different hand grips, finger pushups, and knuckle pushups through dynamic motion (full range motion and partial range of motion) and static position (yielding isometrics and overcoming isometrics) with added resistance in one machine. Also, the user can quickly change the weight, and multiple users can perform pushups with added resistance together with no muscular effort lost from lifting weight plates and placing them in pegs. The user can also perform pushups with added resistance using pushup bars and exercise equipment of their choosing. Furthermore, the maximum pushup exercise machine has the additional advantages in that:
The above-described embodiment is not intended to limit the scope of the present invention, as one skilled in the art can, in view of the present invention, expand such embodiment to correspond with the subject matter of the present invention claimed below. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
The advantages set forth above, and those made apparent from the foregoing description, are efficiently attained. Since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention that, as a matter of language, might be said to fall therebetween.
