1. Field of the Invention
This application relates generally to a bike trainer and, more specifically, to a bike trainer apparatus to be installed on a treadmill for supporting a bike at a position that allows the bike's wheels to roll over a treadmill belt.
2. Description of Related Art
Conventional bike trainers have traditionally supported the rear wheel of a bike at an elevation above the ground to allow the rear wheel to rotate without advancing the position of the bike forward. A resistance wheel provided to the trainer is urged against the bike's rear wheel to exert a resistive force against rotation of the bike's rear wheel, attempting to slow the bike's rear wheel at all times. This resistance against rotation of the rear wheel is intended to give the rider a sensation similar that experienced by the rider when riding the bike over a roadway or other ground surface.
However, such conventional trainers require the front wheel of the bike to remain stationary. The front wheel rests on the ground near the trainer that is elevating the bike's rear wheel, or on a platform that supports the front wheel at about the same elevation as the rear wheel. Without rotating or otherwise moving laterally, the stationary front wheel provides the user with a monotonous training experience that is much different from the experience of actually riding a bike.
More recently, attempts have been made to mount a bike on a device that allows rotation of the front wheel synchronously with rotation of the rear wheel. For example, the trainer can be provided with a front roller that is linked to the resistance wheel. The linkage between the front roller and the resistance wheel causes the front roller to rotate at the same angular velocity as the resistance wheel. Similarly, other attempts have utilized a front restraint system that connects to the forward portion of a bike or other mounting assembly that maintains a position of the bike on a treadmill-type device. However, all such devices are dedicated exercise devices specific to bike training. As such, they are not suitable for use in activities other than bike training, or include bike mounting hardware that is integrally formed as a single, monolithic unit as part of the treadmill frame.
According to one aspect, the subject application involves a bike trainer, and an exercise apparatus with a bike trainer for supporting a bike at a position that allows wheels provided to the bike to roll over a belt of a treadmill. The bike trainer includes a mounting bracket adapted to be non-invasively installed on a frame of the treadmill utilizing a releasable fastener. The releasable fastener is adjustable from a first state in which the releasable fastener secures an installation of the mounting bracket on the frame to a second state in which the mounting bracket is removable from the frame. A plurality of arms are coupled to the mounting bracket and each include a distal end to be positioned at an elevation vertically above an elevation of the belt of the treadmill. A bike coupler is provided adjacent to the distal end of at least one of the arms, and is adapted to cooperate with a portion of the bike to couple the bike to the bike trainer apparatus and maintain the bike over the belt of the treadmill.
According to another aspect, the subject application involves an exercise apparatus for use in training for biking and running. The exercise apparatus includes a frame with a plurality of frame rails laterally spaced apart from each other. A roller is rotatably supported between the plurality of frame rails adjacent to a first end of the frame along a longitudinal axis. A tensioning member is supported between the plurality of frame rails adjacent to a second send of the frame, opposite the first end of the frame, along the longitudinal axis. A belt extends about the roller and the tensioning member, and an electrical motor is operable to rotate the belt about the roller and the tensioning member. A bike trainer apparatus is removably coupled to the frame for supporting a bike at a position that allows wheels provided to the bike to roll over the belt of the treadmill while the belt is rotating about the roller and the tensioning member. The bike trainer apparatus is separable from the frame without damaging the frame, and includes a mounting bracket non-invasively installed on the frame of the treadmill utilizing a releasable fastener. The releasable fastener is adjustable from a first state in which the releasable fastener secures an installation of the mounting bracket on the frame to a second state in which the mounting bracket is removable from the frame. A plurality of arms are coupled to the mounting bracket and each includes a distal end to be positioned at an elevation vertically above an elevation of the belt of the treadmill. A bike coupler is also provided adjacent to the distal end of at least one of the arms. The bike coupler is adapted to cooperate with a portion of the bike to couple the bike to the bike trainer apparatus and maintain the bike over the belt of the treadmill, allowing the wheels of the bike to roll over the belt while the treadmill is operational.
The above summary presents a simplified summary in order to provide a basic understanding of some aspects of the systems and/or methods discussed herein. This summary is not an extensive overview of the systems and/or methods discussed herein. It is not intended to identify key/critical elements or to delineate the scope of such systems and/or methods. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The invention may take physical form in certain parts and arrangement of parts, embodiments of which will be described in detail in this specification and illustrated in the accompanying drawings which form a part hereof and wherein:
Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Relative language used herein is best understood with reference to the drawings, in which like numerals are used to identify like or similar items. Further, in the drawings, certain features may be shown in somewhat schematic form.
It is also to be noted that the phrase “at least one of”, if used herein, followed by a plurality of members herein means one of the members, or a combination of more than one of the members. For example, the phrase “at least one of a first widget and a second widget” means in the present application: the first widget, the second widget, or the first widget and the second widget. Likewise, “at least one of a first widget, a second widget and a third widget” means in the present application: the first widget, the second widget, the third widget, the first widget and the second widget, the first widget and the third widget, the second widget and the third widget, or the first widget and the second widget and the third widget.
Accordingly, there is a need in the art for a bike trainer apparatus that can be retrofit to a treadmill for supporting a bike in a manner that allows the bike wheels to roll over the treadmill's belt to simulate a bike ride over a ground surface. Such a bike trainer apparatus can be non-invasively installed on the treadmill without permanent physical alterations of any portion of the treadmill, allowing the bike trainer apparatus to be removed from the treadmill, thereby returning the treadmill to its configuration prior to installation of the bike trainer apparatus. The bike trainer apparatus can also allow for limited lateral freedom of the front wheel of the bike to traverse the treadmill belt in a transverse direction while traveling over the belt 22.
The non-invasive manner in which the bike trainer 30 can be installed on the treadmill 10 does not involve any physical modifications of the frame 12, frame rails 14, or other portion of the treadmill 10 from a configuration of the treadmill 10, as purchased, specifically for installation of the bike trainer 30. In other words, the bike trainer 30 can be installed on an existing treadmill 10 that was not built or manufactured with the intent to be utilized for bike training (i.e., involving bike wheels rolling over the moving belt 22). Such a treadmill 10 can optionally be a treadmill 10 specifically adapted for run training, walking, and other activities where a user walks, runs, jogs, or otherwise travels by foot over the moving belt 22. According to other embodiments, the treadmill 10 can include a structural feature anticipating the later installation of a bike trainer 30. For example, a manufacturer of the treadmill 10 may include a pivot pin similar to that described in detail below to which the arms 56 can be coupled. The bike trainer 30 described herein can be coupled to such pins yet still be considered to be non-invasively installed on the treadmill 10. Removing the bike trainer 30 from the treadmill 10 according to such an embodiment does not result in damage to the treadmill 10, and returns the treadmill 10 to its configuration prior to installation of the bike trainer 30. The treadmill 10 can optionally include a motor 24 and/or linkage between the motor 24 and one or more of the rollers 16, 17 to drive the belt 22 at angular velocities faster than a user can achieve on foot, but are commonly encountered on a bike 32. Because the bike trainer 30 includes non-invasive installation structure, the bike trainer 30 can be installed on the treadmill 10 without drilling holes in, welding to, or otherwise physically altering any portion of the treadmill 10 such as the frame rails 14, for example. As a result of this non-invasive installation, the bike trainer 30 can subsequently be removed from a treadmill 10 on which it has been installed to return the treadmill 10 to its physical configuration prior to installation of the bike trainer 30.
The bike trainer 30 can be removably coupled to the frame 12 via the non-invasive installation techniques described herein, or any other technique that does not require a physical alteration of the treadmill 10, for supporting a bike 32 at a position that allows wheels 34, 36 provided to the bike 32 to roll over the belt 22 of the treadmill 10 while the belt 22 is being rotated by the motor 24. The bike 32 can optionally be supported at a location where the rear wheel 34 rolls on the belt 22 as it passes over the roller 16. In other words, the belt 22 can be disposed between a tire provided to the wheel 34 and the roller 16. As mentioned above, the non-invasive installation of the bike trainer 30 allows it to be separable from the frame 12 without damaging or otherwise physically altering the frame 12.
As shown in
In addition to interfering with the removal of the mounting brackets 37 from their respective frame rails 14, the interior clamping members 40 each have a pivot pin 52 fixedly secured thereto. For instance, a pivot pin 52 can be welded to each of the interior clamping members 40. Each pivot pin 52 can be a cylindrical-shaped metal rod that extends partially across, but less than the entire distance separating the mounting brackets 37 under the belt 22 of the treadmill 10, as shown in
An adjustable foot 55 (
According to an alternate embodiment, adjustment of the height that a frame coupler 68 is supported by the arms 56 above the belt 22 can be achieved through adjustment of a cam embodiment of the pivot pins 52. An example of such an embodiment is shown in
The pivot pin 52 can extend through the interior clamping members 40, and extend beyond the interior clamping members 40 a length approximately equal to the width W, shown in
An alternate embodiment of the mounting brackets 37 is shown in
Each of the embodiments includes an arm 56 extending from each of the mounting brackets 37 that supports a frame coupler 68 that cooperates with opposite ends of a hub 70 (
The frame coupler 68 is located adjacent to the distal end of at least one of the arms 56, and is adapted to cooperate with a portion of the bike (e.g., the hub 70) to couple the bike 32 to the bike trainer 30 and maintain the bike 32 over the belt 22 while the treadmill 10 is operational. A first adjustor 72 is operable to vary a distance separating the hub receivers 74 to establish a rough separation of the hub receivers 74 suitable to loosely receive the opposite ends of the hub 70. According to the present embodiment, the first adjustor includes a threaded member 76 that supports one of the hub receivers 74. A second adjustor 78 can be different than the first adjustor 72 (e.g., a cam lock adjustment device), that is operable to vary the distance separating the hub receivers 74 established using the first adjustor 72 and establish a final separation of the hub receivers 74 suitable to secure the hub 70 between the hub separators during operation of the treadmill 10. For instance, the cam lock mechanism includes a lever 79 fixedly attached to a cylindrical member 80 supporting the hub receiver 74. A guide groove 82 defines the range of allowable travel of the lever 79, and accordingly, the allowable rotation of the cylindrical member 80, to urge the hub receiver supported by the member 80 toward the opposing hub receiver 74, thereby securing the hub 70 there between.
Illustrative embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above devices and methods may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations within the scope of the present invention. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
