Open Handgrip for an Exercise Machine
A handgrip which has two terminating ends that does not connect with the other components to form a closed loop but instead form an open loop in the form of a “C”, inverted “C”, “U”, or inverted “U” depending on the side of the exercise machine the grip is to be used on and the manner of viewing it. This is commonly referred to as an open structure as this provides for a handgrip which does not fully circumscribe an area. It only partially circumscribes an area and creates a structure with two terminating ends on each handle.
This application claims the benefit of U.S. Provisional Patent Application Ser. No.: 62/131,484, filed Mar. 11, 2015, the entire disclosure of which is herein incorporated by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
This disclosure relates to the field of arms and handgrips for cardiovascular exercise machines. In particular, to handgrips which include mounted controls and an open grip design.
2. Description of the Related Art
The benefits of regular aerobic exercise for individuals of any age is well documented in fitness science. Aerobic exercise can dramatically improve cardiac stamina and function, as well as leading to weight loss, increased metabolism and other benefits. In order to allow people to perform aerobic exercises without having to go outside or to large sports complexes, fitness machines have been developed to allow a user to perform aerobic exercises in fitness centers or a small area of their home.
Exercise machines that are designed to be used when the user is standing upright are commonly categorized into three major groups. The first of these is treadmills, where a user walks or runs on an endless conveyor belt. Treadmills are generally the most common form of cardio exercise device as they are simple to understand and operate and they provide for a very natural exercise motion. The second classification is a stair stepper. Stair steppers are designed to provide the user with a significantly vertical movement simulating climbing stairs. This can be performed through the use of a specially shaped treadbelt, or through the use of vertically actuated footpads. The third type of device is an elliptical exerciser.
The elliptical exerciser (also known as an “elliptical machine”, “elliptical cross-trainer”, or “glider”) have become very popular due to their ease of use and their provision of relatively low-impact aerobic exercise. Generally in these types of machines, a user performs a motion using their legs which forces their feet to move in a generally elliptical, racetrack, oval, or elongated circular motion about each other. This motion is designed to simulate the motion of the feet when jogging, walking, or climbing but the rotational motion is “low-impact” compared to jogging or climbing where the feet regularly impact a surface.
In an elliptical machine, the user's feet do not leave the footpads of the machine in most cases and the footpads smoothly travel through a defined path reducing or eliminating impacts from the user's feet striking the surface. In many respects, the motion could be considered more akin to a pedaling motion than a walking motion, but because the exercise is performed standing up, and with an elongated elliptical motion as opposed to a circular pedaling motion, the motion feels more like a striding walk, ski, or “glide”.
Regardless of the type of cardiovascular machine used, these machines traditionally function to exercise the user's cardiovascular system through exertion of the skeletal muscles of the lower body, but do not exercise the upper body to any significant extent. Recently, however, cardiovascular machines of this type have begun to adopt moveable arms and handgrips whose motion is interlinked with the motion of the user's feet. Pushing and pulling on these arms often goes hand in hand with the user having to move their feet on the machine providing an upper body exercise. This type of full body exercise is particularly valuable on elliptical machines, stair steppers, and unpowered treadmills where the motion of the user's feet usually serves to provide the motion to the user. Essentially, in these machines, the user's motion serves to drive the machine. This is different than in powered treadmills where a motor turns the belt and the user is forced to walk or run to avoid being pushed off.
These upper body exercise systems have traditionally used arm members which are independently moveable against the resistance of a spring or friction plate in a swinging motion to provide for an upper body workout in conjunction with the cardiovascular and lower body workout while still providing a fairly natural movement. However, more modern versions operate the arms in conjunction with the movement of the feet where movement of both the upper and lower body is interlinked and serves to drive the same ultimate components of the machine. Thus, the two parts of the body work together to drive the machine.
SUMMARY OF THE INVENTIONThe following is a summary of the invention in order to provide a basic understanding of some aspects of the invention. This summary is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.

The following detailed description and disclosure illustrates by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the disclosed structures and methods, and describes several embodiments, adaptations, variations, alternatives and uses of the disclosed structures and methods. As various changes could be made in the above constructions without departing from the scope of the disclosures, it is intended that all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
Although the machines, devices, and methods described below are discussed primarily in terms of their use with a particular layout of an elliptical exercise motion machine where a rotational crankshaft is on the back of the machine and the machine provides moving pendulum arms, one of ordinary skill in the art would understand that the principles, methods, and objects discussed herein could be adapted, without undue experimentation, to be useable on any elliptical motion or other exercise machine which generates its motion through the use of any mechanisms.
The use of moveable arms (105) in exercise machines (109) is relatively common and increasingly popular, but moveable arms (105) often have a number of concerns. In the first instance, moveable arms (105) often need to be quite large so as to accommodate a variety of different sized users and, as a result, the moveable arms (105) often stick up quite high to provide sufficient and comfortable rotation. This means that the range of motion of the moveable arms (105) is often quite large and there is concern that components of the moveable arms (105) can hit a user (101), hit a bystander, or get in the way of the user (101) while exercising.
A second concern with moveable arms (105) is that the moveable arms (105) often need to provide a variety of handgrip positions in order to provide for a comfortable hand position for the user. Often, the most comfortable position will vary depending on the type of motion, or intensity of exercise, the machine (109) is providing. For example, a more vertical handgrip may be desirable for a machine (109) providing a motion more akin to cross country skiing as ski poles are generally gripped vertically. However, a machine (109) providing a more vertical climbing motion will often provide grips that are more horizontal in order to simulate the rungs on a ladder. For machines (109) that can provide for a variety of different motions, such as the one depicted in
Another problem with traditional handgrips, particularly when they are on moveable arms (105), is that it is often difficult for a user (101) to let go of the grips during an exercise to perform other actions. Exercise machines (109) have traditionally been controlled by a console (111) which is mounted to face the user (101) at a relatively high position. This allows the user (101) to reach the console (111) before, during, and after exercising to observe feedback from monitors in the machine (109) (such as, but not limited to, the distance travelled) as well as to alter specifics of the exercise being performed (such as, but not limited to, its intensity or difficulty). The console (111) also may provide entertainment options, including controls for built in audio or video content or just a simple rack for holding a book or magazine.
As should be apparent from
The grips, arms, and methods described herein are discussed primarily in terms of their use with a particular layout of an elliptical exercise machine (109), such as that shown in
The structure of the arm (201) is such that it provides an upright (211) which is effectively the portion which would generally interconnect the arm (201) at its axis of rotation (113) to the machine (109). In the depicted embodiment of
The upright (211) will generally be a rigid tube, often constructed of metal or strong plastics. The upright (211) tube will generally have a circular or elliptical cross section so as to eliminate sharp corners and provide for a smother surface, but this is by no means required. In some embodiments, the upright (211) may be relatively linear, however, in others the upright (211) may comprise a curve or bend to provide for a desirable shape and position the handgrip (203) where desired. Generally, the center longitudinal axis of the upright (211) will be arranged so as to be within a single plane (e.g. the tube is “planar”).
It should be apparent from
It should be clear from.
For purposes of this disclosure, terms such as “inward”. “outward”, “upward” and “downward” are used to contemplate relative positions of components. These terms are used since structures in the arm (105) on one side of the machine (109) are generally mirrored to the arm (105) on the opposing side. Thus, it is not possible to absolutely describe the relationship of the pieces on any one arm (105) as it would only be specific to the arm (105) for the specific side with the other side being a mirror image. Further, structurally, the two arms (105) could generally be interchangeable. While doing so would likely render the machine (109) unusable for the standard user, there may be situations where a left arm is placed on the right and vice versa. Thus, this disclosure uses language of relative positioning for improved clarity.
As used herein “inward” means that assuming the upright (211) moves in a plane generally perpendicular to the torso of the user (101) which is positioned generally to one side of the user (101). Thus, something extending “inward” will extend out from the plane in a direction toward the opposing side of the machine (109) (across the user's torso). Similarly, the term “outward” is opposite to “inward” and means an extension out from the plane in a direction away from the opposing arm (105). The term “upward” as used herein means generally the vertical direction from the axis (113) to the highest point of the arm (105). “Downward” would mean the opposite of “upward.” Finally, “forward” will generally be the direction that a user (101) exercising on the machine (109) will push the arm (105) and “backward” or “rearward” will generally mean the direction the user (101) will pull the arm (105). Further, the use of any one term is not exclusive to the possibility that a component could not extend in other directions. Thus, a component indicated to extend inward, would extend inward but may also extend forward, backward, or neither. Further, a component indicated to extend inward could also extend upward, downward or neither.
In the depicted embodiment of
The grasping of the first vertical extension (213) will generally be accomplished by the user (101) in a traditional vertical “mug-type” grip where the user will wrap their fingers around the first vertical extension (213). The grasping would traditionally have them wrap their thumb in an opposing direction around the first vertical extension (213). In the depicted embodiment of
However, as is shown in the depicted embodiment, the first vertical extension (213) has a terminating end (215) and does not connect with the other components to form a closed loop. This is commonly referred to herein as a “open” structure as this provides for a handgrip (203) which does not circumscribe an area. It only partially circumscribes an area and creates a structure with two terminating ends on each handle (105). Because of this structure, the user (101) need not wrap their thumb around the first vertical portion (213), but may instead place it on top of the terminating end (215).
The terminating end (215) of
Upon the area (219) there will commonly be placed a control panel (291A) or (291B). The control panel (291A) or (291B) is essentially a small button pad duplicating some of the controls available on the console (111) and will often comprise a touch screen or button surface which allows for buttons or other activation objects to be placed thereon. An embodiment of two button pads (291A) and (291B) are shown in
In the embodiment of
In the embodiment of
The pinch point (233) means that the user (101) is generally discouraged from grasping the lower horizontal extension (231) in the manner of grasping a bike handlebar right at the corner (233). Instead, because of the pinch point (233), the user (101) will generally rotate their thumb and have their thumb wrap around the upright (211) right around the transition point to the first vertical extension (213). This is a more natural position of the hand, and inhibits the user from grasping the lower horizontal extension (231) too hard, which can result in them putting too much weight on it and not getting a full exercise benefit.
As one continues around the lower horizontal extension (231), it converts into a lower curved portion (241), a second vertical extension (251), an upper curved portion (261), and then a second horizontal extension (271). As can be seen, these are arranged to form a generally “C” shape for the left handgrip (203) of
The primary advantage of having natural handgrip positions on the second vertical extension (251) and the upper horizontal section (271) is that these positions allow a user (101) that is larger (e.g. wider and/or taller) to grip the handgrip (203) at a position further from their body either outward or upward, depending on the type of grip desired and different from that which can be obtained from the first vertical extension (213) or lower horizontal extension (231). In order to enhance the feel, the handgrip (203) may be coated with a textured or rubberized surface as is known to those of ordinary skill in the art.
It should be apparent from
It should be clear from the above that there are a number of benefits of including two ends (215) and (275) in the handgrip (203) through the inclusion of an open structure. It is often comfortable for a user to grasp a tube in the handgrip (203) with their thumb over an end. Biomechanics of the human hand generally place the thumb to the inside of the index finger when the fingers are curled, not below it as is the case when grasping a tube. Grasping of a tubular grip between its ends at a position where its end is not within reach of the thumb, the thumb is generally positioned downward (as opposed to inward) of the index finger. Having ends (215) and (275) be available for the thumb to go over, therefore, provides a more natural position as the thumb can go over the end (215) or (275) with the fingers placed on top of the tube, or on an appropriate side.
Instead of first vertical extension (213), the embodiment of
As can be best seen in
In all the above embodiments, the handgrip has two terminating ends that do not connect with the other components to form a closed loop but instead form an open loop in the form of a “C”, inverted “C”, “U”, or inverted “U” depending on the side of the exercise machine the grip is to be used on and the manner of viewing it. This is referred to herein as having an open structure as this provides for a handgrip which does not fully circumscribe an area. It only partially circumscribes an area and creates a structure with two terminating ends on each handle.
While the invention has been disclosed in connection with certain preferred embodiments, this should not be taken as a limitation to all of the provided details. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention, and other embodiments should be understood to be encompassed in the present disclosure as would be understood by those of ordinary skill in the art.
