Running and riding exercise device

Abstract

First and second sets of right and left double link members (13) are provided. And the first group of right connecting rod component and left connecting rod component are connected with a rotating shaft (11) in the frame (2). A second set of right and left link members (29) is connected to the first set of left and right link members, while these connections (17) are positioned radially with respect to the axis of rotation in the frame. The connection portions between the first and second link members on the right and left sides are arranged at 180 degrees with respect to each other. A foot support (35) is connected with the second set of crank arms and is located in the longitudinal direction of the connection between the first crank arm and the second crank arm. When the first set of crank arms rotate forwards by 360 degrees, the second set of crank arms can swing and rotate forwards to move forwards in a one-way mode, so that a user is allowed to run and exercise in a more natural moving mode, and the exercise is called running and riding exercise.

Description

Cross Reference to Related Applications This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 454,128, filed March 23, 2023, entitled “RUNNING AND CYCLING EXERCISE DEVICE,” the contents and filing of which are incorporated herein by reference in their entirety. BACKGROUND

[0001] The present invention relates to an exercise device, and in particular to a hybrid running device.

[0002] Running and cycling are two cardiovascular exercises that many people participate in. Exercise fitness devices, equipment, machines, etc. are well known and include bicycles, upright bicycles, recumbent bicycles, hybrid bicycles, climbing devices, cross-country skiing equipment, elliptical machines, exercise hybrid equipment, rowing machines, stair climbers, step climbers, stride machines, treadmills, etc. Some of these devices attempt to mimic the running motion, some claim to replace running, etc., but none fully achieve the same natural motion, power, and force pattern that the runner themselves exert and feel as in actual running.

[0003] The effect of the forces observed by the eye running is shown in the runner’s movement on the ground. We can see the biomechanics of the runner moving along the ground and the speed, but the naked eye cannot see the forces that go down into and through the ground. These forces are essentially downward and curvilinear in nature into and against the ground. The runner drives the knee, thigh upward, forward, and then downward, creating a push against the ground. In the present invention, a person can actually run in a manner similar to running, which allows the user to drive their knee, thigh upward, forward, and then downward and create a push against the resistance force. These forces also translate downward and curvilinear as seen physically when the user travels through an extended and varied range of motion path with the device.

[0004] The aforementioned devices, machines other than treadmills have fixed, semi-fixed, limited, predetermined movement patterns. These devices with left and right side linkage systems are fixed relative to each other and work in unison, and the second linkage members do not have any independence from each other. Some of these exercise devices have fixed movement patterns that can be adjusted mechanically manually by control and / or electronically by control, for example, changing the angle of a certain aspect, but still moving in a predetermined movement pattern. They do not properly adapt to the height, leg length, stride, and step of different users, nor do they properly adjust the changes in stride and step based on the natural force and speed of the user during exercise. The movements allowed for the user tend to have a smaller limited circumference compared to the range and movements of natural running, limiting and reducing the range of movement of the user. Here are some examples of devices that do not meet the requirements of the current invention: the bicycle type device of US Patent No. 7,140,626; the elliptical machine devices of US Patent Nos. 11,000,730 and 9,468,798; the hybrid device labeled "pendulous" of US Patent No. 7,780,577; the treadmill device of US Patent No. 10,207,147; and other devices with only a limited circular foot support travel path and only for cycling, such as the crank arm device of US Patent No. 7,607,370 and the Hase Bikes shortened crank arm device (see: https: / / hasebikes.com / media / hase-bikes-catalog-2022.pdf page 80). Each of these references is incorporated herein by reference for all it contains, including the references contained therein.

[0005] The present invention overcomes these limitations, allowing the user to utilize a more natural running movement. The range of movement is wide, allowing for a comfortable wide range and circumference similar to natural running. The user can lift their knees up and forward, and can move at a faster pace, thus lengthening their step movement pattern. The movement pattern of the present invention has a maximum parameter movement pattern, but allows the user to freely and naturally adjust their movement pattern within the wide range of variation within the external full limit allowed by the invention, by exerting their own force while exercising. The movement pattern exerted by the user is not predetermined, but is the result of the action based on the force, speed, and technique of the user while running, cycling, and exercising.

[0006] The aforementioned devices, machines other than treadmills also have foot supports fixed in their respective positions, and a fixed width is configured between the foot supports.

[0007] The present invention overcomes these limitations by allowing the user to freely move their feet connected to the foot supports both inward and outward while exercising to vary their step width. This makes the step width more natural and individualized while running, cycling, as well as walking, jogging and running.

[0008] Some elliptical machines and hybrid devices are based on visual motion giving the illusion of running, but do not simulate the power of running. Some elliptical machine devices are more akin to cross country skiing, where the force applied by the user is often linear. Yet other elliptical machine devices have similarities to cross country skiing and semi-stride motion. In addition, this type of device reduces the effort required by the user to lift their own leg while exercising. When one leg is forced downward, the device lifts the other leg upward.

[0009] Treadmills generally have components that allow the user to move their legs, feet in a very limited set of patterns. They tend to move up and down along an angled straight line.

[0010] Stair-climbers are moving staircases, also known as stair-mills. They consist of steps that replicate a set of stairs moving, rotating at an inclined angle. Similar to treadmills, but with steps, stairs. The user steps on a step, lifts the body by extending the leg downward, the foot moves at a fixed angle, then the other leg steps on the next step with the same motion. This motion is fixed.

[0011] Bicycles; stationary bicycles configured on a frame and / or bicycles configured on a frame with wheels. Bicycles provide aerobic and / or anaerobic exercise that can enhance and condition the leg and hip muscles. Bicycles provide a user's feet with a circular motion that is widely accepted and quite comfortable, but the distance from the right crank arm and left crank arm to the connecting axis is pre-set and fixed. In addition, if the user does not use a shoe clip, toe clip, etc. to connect the user's feet to the foot supports, this type of device reduces the effort required by the user to lift their own leg while exercising. Because when one leg is forced downward, the device lifts the other leg upward.

[0012] The width between the user's feet while pedaling is different than while walking, running. The typical Q-factor for a pure pedal is 150mm to 170mm. These mentioned exercise devices have limitations and narrowness in range and motion flexibility. The width of walking, jogging and running is much smaller than the typical Q-factor for cycling. The step width or stride of an adult human is typically between 25mm to 77mm.

[0013] Treadmills allow the freedom of natural running biomechanics with natural stride, step width, and gait, unlike other exercise devices. In addition, treadmills can have a cushioned, shock-absorbing surface that can reduce but not eliminate the impact on the body of a runner when running on other types of ground (e.g., ground, pavement, etc.). Bicycles are considered to have virtually no impact.

[0014] Treadmills are significantly deficient in reducing impact when running, while other exercise devices are significantly deficient in allowing the comfort and effectiveness of free, natural movement from natural running.

[0015] Patents cover a large number of inventions for bicycles, crank arms, elliptical machines, step machines, and combinations thereof, but none teach or anticipate the present invention, either independently or in combination.

[0016] The present invention is a unique, innovative synergistic configuration that provides a novel exercise device, "RunCycle." SUMMARY

[0017] The present invention relates to an exercise device.

[0018] Embodiments of the present invention facilitate more natural running and rotational cycling movements, with the user being able to self-adjust changes in running movements and stride in real time according to their own physical, autonomous biomechanical effort and strength. It allows the user to flexibly adjust changing movements, changing pace, stride, and step width in real time while exercising, with the changes being user-directed. The user can freely, automatically adjust their movements within the allowed maximum range of extension, thereby achieving changing, self- prescribed path of travel movements, which include both running and curvilinear movements, referred to as "RunCycle."

[0019] Some embodiments of the present invention allow, encourage, and facilitate the user to drive their knees upward and forward, thereby enhancing healthy running biomechanics. This can reduce impact on the user's body, if any, to a degree similar to that of cycling a bicycle.

[0020] In one embodiment, the exercise device of the present invention can include or consist of a frame that can be positioned on a support surface, floor, ground, etc. The components of the exercise device, such as the running cycling exercise device, are attached and connected to the frame. These components can include or consist of, but are not limited to, handlebars, upper torso supports, link members (e.g., link tubes, crank arms, crank disks, and crank pulleys), cantilevered configurations of link members, link attachments, crank attachments, connectors, one-way clutch devices, friction reduction devices, bearings, angular load devices, radial load devices, axial load devices, foot supports, rotating foot supports, laterally or horizontally moving foot supports, foot support shafts, pedals, pedaling mechanisms, axes, axles, drive shafts, crankshafts, bottom brackets, sprockets, gears, chain gears, pulleys, flywheels, wheels (which can be used with direct gears, drive gears, chains, belts, actuators, etc.), resistance devices, flywheels, weighted flywheels, brake systems, electromagnetic systems, wheels, etc. for adjusting the resistance of the pedaling, rotating mechanisms. Additionally, the exercise device can also have a seat and / or handlebars. The exercise device can be a stationary exercise device.

[0021] As used herein, the first set of link members can include crank arms, crank disks, and crank pulleys, which can be used interchangeably with each other. The crank disk can be configured to function as a first crank arm. The crank disk can also be configured to function as a crank pulley, which is used in the drive system and configured to also function as a first crank arm (also referred to as a pulley).

[0022] In various embodiments, the user will interact with the exercise device by placing, integrating, and / or securing the feet on the foot supports. The foot supports can include or consist of pedals, pedals with straps, toe clips, etc., and / or shoe attachments, foot insert connectors, etc. Additionally, the foot supports can also be incorporated on a foot support shaft. The foot supports can be configured to rotate, such as around the foot support shaft. Additionally, the foot supports can also be configured to move laterally, i.e., horizontally, where the lateral direction can be parallel to the axial direction defined by the foot support shaft and / or the axle axis. These two aspects of rotation and lateral movement can be performed simultaneously by the user while exercising (running cycling).

[0023] One end of the first link member, such as a crank arm, is typically attached to an axle, such as an axis type axle. The axis type axle can work in conjunction with a drive system. The drive system can have resistance. The exercise device can include a resistance device. For example, for stationary exercise type devices, such as but not limited to: stationary bicycles, treadmills, elliptical devices, elliptical type devices, etc., the resistance device can include various applications, such as electromagnets, eddy current systems, generators, magnets, alternators, brakes, flywheels, friction devices, pads, belts, fans, etc. In another example of an exercise device, such as an outdoor bicycle with wheels, resistance can be provided by moving along a surface, such as the ground, based on gravity, air resistance, and the speed of the user, exerciser, in action and effect.

[0024] These exercise devices with resistance typically work in conjunction with an axle and crankshaft mounted in a base support, which can drive a drive system, which can include various components mentioned herein, flywheels, generators, magnets, etc., working through direct drive, gears, belts, or chains, etc.

[0025] The resistance can be controlled manually, mechanically, and / or electronically by the user. Mechanical controls can include, but are not limited to: knobs, switches, pull devices, etc. Electronic controls can include, but are not limited to: direct or remote electrical controls, computers, networks, WiFi, cell phones, etc. Programs can be manually operated and / or pre-set and / or designed and manually and / or electronically operated.

[0026] Additional components and / or features include, but are not limited to: computer control / electronic / WiFi / multi-user WiFi connectivity / instantaneous / packetized / categorized / pre-programmed programs including user weight and percentage of grade, such as incline or decline of terrain, which can be set in programs / real world simulation / virtual world animation / interactivity available today.

[0027] Actuators can also be used to change the orientation, grade, angle of the frame relative to the ground.

[0028] In one embodiment of the invention, the exercise device (e.g., a treadmill / cycling device) has two sets of linkage members connected together, forming and including a left linkage system application and a right linkage system application. The first set of linkage members may be connected to an axis and / or an axis attached to a frame (e.g., the aforementioned frame). The first set of linkage members (e.g., a first set of first linkage members) is rotatable about an axis in the frame. The second set of linkage members (e.g., a second set of second linkage members) may be connected to the first set of linkage members and may be located at a position away from the axis in the frame connected to the first set of linkage members. "Located distally" can refer to a distance measured radially from the axis of rotation. In the context of this disclosure, a distal position may be equivalent to a radial and / or longitudinal position. The connection between the second linkage member and the first linkage member of the left and right linkage members may be positioned 180 degrees relative to each other. Therefore, when the left connection between the second link member and the first link member is located at the 12:00 o'clock position, the right connection between the second link member and the first link member is located at the 6:00 o'clock position.

[0029] In another embodiment of the invention, the exercise device (e.g., a treadmill / cycling device) has at least three sets of linkage members connected together, forming and including a left linkage system application and a right linkage system application. The first set of linkage members can be connected to an axis and / or an axis attached to a frame (e.g., the aforementioned frame). The first set of linkage members can rotate about this axis in the frame. The second set of linkage members connected to the first set of linkage members is located at a position away from the axis in the frame connected to the first set of linkage members, i.e., a radial or longitudinal position. The connection between the second linkage member and the first linkage member of the left and right linkage members can be positioned 180 degrees relative to each other. Thus, when the left connection of the second linkage member to the first linkage member is located at the 12:00 o'clock position, the connection of the right second linkage member to the first linkage member is located at the 6:00 o'clock position.

[0030] Furthermore, in the embodiments described above, the connection between the second link member and the first link member of the left and right link members can be positioned 180 degrees relative to each other, allowing the connections on both sides to work together and rotate synchronously, and to be fixed, while the second link member can rotate unidirectionally and swing independently upward and forward. The first link members are typically connected and configured so that both rotate simultaneously in the same direction. The second link members can be configured to rotate or pivot independently of each other. Additionally, one or both of the second link members can be configured to rotate or pivot independently of the corresponding first link members attached thereto.

[0031] The one-way mechanism can be coordinated with the connecting portions of the first and second set of link members (e.g., crank arms) and the connecting portions therebetween in a number of different ways. The weight and force of a user placed on the foot support (preferably a pedal) can exert a downward force on the one-way connections of the first and second link members (e.g., crank arms) and can exert a diagonal, angular load force on the one-way connections of the first and second link members. In this disclosure, the term "one-way rotatable" can mean rotatable in only one direction, e.g., clockwise or counterclockwise, while the other direction is blocked. The term "rotatable" can mean rotatable in at least one direction or both directions if not otherwise specified.

[0032] In embodiments of the dual set of link member configuration, the connecting portions that connect the second set of link members and the first set of link members (e.g., crank arms) together are to provide support, transfer, transmit force, assist alignment, guide, transmit motion, reduce friction, and facilitate relative rotation and movement between parts, components, etc. A one-way clutch load device can be used in this configuration. Additionally, a one-way clutch load device and an angular load device can also be used in another configuration. These devices can be one device or more than one device configured to coordinate with the connecting portions of the second link members and the first link members, e.g., crank arms.

[0033] In one embodiment, the left side second link member can be configured to rotate clockwise one-way, while the right side second link member can be configured to rotate counterclockwise one-way. In another embodiment, the left side second link member can be configured to rotate counterclockwise one-way, and the right side second link member can be configured to rotate counterclockwise one-way. As shown below, the definitions of clockwise and counterclockwise can depend on the point of observation. The left side second link member and the right side second link member can be configured to rotate in the same direction when viewed from one fixed point of observation.

[0034] For applications with a swinging crank arm connected to a first stationary link member (e.g., crank arm, crank disk, crank pulley), there are a number of ways to implement angular load support. A friction reduction application coordinates with moving parts, sleeves (possibly made of industrial plastic, resin, metal, etc.), angular contact bearings (one or more configurations, etc.) to reduce friction and maintain stable motion of the swinging crank arm while protecting the life and use of the parts.

[0035] In embodiments of the unidirectional device, the friction reducing device, mechanism, bearing, etc. is configured with a connection to counteract the downward force. In addition, a device, mechanism, bearing, etc. of the angular, radial, axial, diagonal load type is installed to counteract the diagonal, angular load and force configured to the connection, or an integrated device containing all of the above characteristics is used for the unidirectional device and the friction reducing device to counteract the angular, radial, axial, diagonal force, all of which are configured to the connection between the first and second link members (e.g., crank arms). This configuration can also provide load support for the extension and downward movement of the second crank arm, and support the angular, radial, axial, diagonal load and force on the second crank arm.

[0036] Embodiments of the unidirectional and angular device can be configured in several different ways. It can be a unidirectional and angular load device in a single housing unit. It can be a unidirectional device arranged adjacent to an angular load device. It can be one device inserted into another, such as into each other, like using a pipe axle, allowing one component inside the pipe and the other outside the pipe. They can be aligned adjacent to each other in any order. There can be multiple identical unidirectional and angular load devices. They can also be configured in a way that shares the same housing, connection points, and components. The connection attachment can include or consist of a unidirectional rotation device. The rotation device can be inserted into either link member (e.g., crank arm), or into a combination of both link members (e.g., crank arms). The connection attachment can be inserted into the unidirectional rotation device, and the connection attachment can be attached to be fixed with or adjustable along the link members such as crank arms. The second link member typically bears downward and angular load, so another bearing, device, etc. can be inserted to counteract the radial and angular load.

[0037] In an embodiment, the internal connection between the first link member and the second link member can include or consist of a shaft, column, rod, axle, etc. suitable for insertion, attachment, connection, etc. of a friction reducing unidirectional clutch device outside the shaft, column, rod, axle, etc.

[0038] In another embodiment of the connection, it can include or consist of a pipe axle suitable for insertion, attachment, connection, etc. of a friction reducing unidirectional clutch device and / or an angular load device outside the pipe axle, and another friction reducing unidirectional clutch device and / or an angular load device inside the pipe axle. Thus, the second link member (e.g., swing crank arm) can swing unidirectionally while having improved angular, axial, and radial strength and stability.

[0039] In a preferred embodiment, the one-way oscillating swing crank arm connected to the swivel connector has a region configured with a ring-shaped blind hole drilled therein. As used herein, the term "ring-shaped hole" can refer to a hole that is ring-shaped. The remaining portion of the ring-shaped blind hole center can be used as a hub that can cooperate with the shaft and / or axis of the radial, axial, angular load bearing device. Further, the radial, axial, angular load bearing device can also be connected to and within the inner wall portion of the tube shaft connector. Additionally, the one-way clutch device can also be connected to and outside of the tube shaft connector. Further, the one-way clutch device can also be connected to and outside of the tube shaft connector. Thus, in this configuration, the swing crank arm has the ability to one-way oscillate while having improved angular, radial, axial strength and stability.

[0040] The first link member, such as a crank arm, and the second link member can be attached, connected to each other in a variety of different ways. The connection can use threaded means, such that there are external and internal thread applications. For example, one threaded component is inserted, screwed into another threaded receiving component, such as external and internal thread applications. Square, hexagonal, tapered inserts, etc. are contemplated for different modes of insertion, receiving, fastening, and securing to each other. The attachment can also be a pressed fit. The first link member and the second link member can be fixed to each other and rotatable relative to each other. By being connected and detachable, the second link member from the first link member, the distance position of the connection point of the second crank arm relative to the axis of connection to the frame and the first link member, such as a crank arm, is adjustable.

[0041] In a preferred embodiment, the distance of the second link member, such as a second crank arm, attached to the first link member, such as a crank arm, relative to the axis of connection of the first link member, such as a crank arm, to the frame is adjustable.

[0042] In a refinement, the second link member, such as a crank arm, can be made of steel, but in a preferred embodiment, the swing second link member of a crank, for example, is made of a lighter material than steel, such as aluminum, titanium, carbon fiber, composite material, industrial resin, plastic, etc.

[0043] The second set of swing unidirectional crank arms are connected to the first set of link members (e.g., crank arms) by attachment, which can utilize a clutch, unidirectional bearing, brake system to allow unidirectional movement, e.g., unidirectional rotation. The amount of swing is not predetermined, but is determined by the user's exertion in natural running. If the user prefers to move in a relaxed manner or slower pace, for example, this is possible, if the user prefers to move in a powerful running manner and faster pace, this is also possible. The user can naturally exert some effort and move in a natural running style, which allows the user to naturally, instantaneously control and change the motion, stride size, range of motion, and path of travel.

[0044] The user connected to the foot support drives the swing crank arms upward, forward by bringing the leg, knee upward, forward. To allow a more natural running motion, the swing crank arms can be made of a lighter material than steel. In addition, the foot support, pedal configuration can also be made of a lighter material than steel. For example, when using aluminum, it is about one third of the weight of standard steel. When running naturally, if wearing shoes, the user only bears the weight of his own legs and shoes, so the effect of using a lighter material, which reduces the weight of the second swing crank arm, allows the user greater freedom to imitate a more natural running motion.

[0045] The movable link members are moved by the force exerted by the user to the link members. For example, in one embodiment, similar to a stationary upright bicycle device with a first set of crank arms consisting of a left crank arm and a right crank arm, the present invention will have an additional second set of left crank arms and right crank arms that can swing forward unidirectionally. The user, exerciser will engage with the foot support, e.g., pedals, and these pedals will allow the user's feet, shoes to be fixed with the pedals so that not only is there a downward force exerted on the pedals, but the pedals can swing freely upward and forward.

[0046] When the first set of link members rotate around the axis attached to the frame, the second set of link members can move, rotate, swing forward unidirectionally. The left and right sides are mirror applications thereof.

[0047] In one embodiment, the foot support can cooperate with the foot support shaft. The foot support can rotate. In addition, the foot support can also move laterally. When the user exercises, runs, rides, both aspects of rotation and lateral movement can be done simultaneously.

[0048] The Q-factor is the lateral or horizontal distance measured from the outside of the second link member. The Q-factor definition used in typical bicycle language defines the lateral or horizontal distance between the outside of one crank arm and the outside of the opposite crank arm. The Q-factor between the user's feet and the minimum step width depends on whether there is a frame and / or components between the foot supports.

[0049] In embodiments where the frame is configured between the left side crank arm link system and the right side crank arm link system, the left side second link member can move, rotate, swing unidirectionally clockwise and the right side second link member can move, rotate, swing unidirectionally counter-clockwise.

[0050] In embodiments where there are components between the foot supports and the foot supports are outside of the frame, such as link members, crank arms, pulleys, gears, sprockets, chains or belts, drive systems, etc., the components limit the Q-factor based on the width of the frame and components, inwardly considering the proximity of the user's foot width while in motion. Between the foot supports. The Q-factor can be adjusted laterally outward and inwardly rearward, the amount of outward adjustment in this configuration being adjusted manually or under the user's own volition while exercising, running, cycling.

[0051] In preferred embodiments, by utilizing the crank disc as the first link member to achieve the minimization and reduction of space between the foot supports, also known as the Q-factor, the crank disc can also be used as a pulley (a.k.a. crank pulley) in cooperation with the drive system. Thus, by utilizing the crank pulley that also serves as the first link member, and no additional pulley, sprocket, and / or gear components of the drive system are needed between the first set of link members. The reduction of additional drive system components helps to reduce the space and width between the foot supports, also known as the Q-factor, which helps the user to feel a more natural running, running cycling motion.

[0052] In another embodiment, the frame and / or drive components can be configured to not be located between the left side link member link system and the right side link member link system, and the left side second crank link member can move, rotate, swing unidirectionally in a counter-clockwise direction, while the right side second link member can move, rotate, swing unidirectionally in a clockwise direction. By configuring the link system without a frame or components in between, a comfortable, natural stride and step width can be achieved.

[0053] In embodiments where no frame and / or components are configured between the left and right foot supports and the foot support shaft, the foot supports can be free to rotate and laterally move so that the user can change the step width > 0 on the fly during exercise, running, cycling or manually pre-adjust the step width prior to exercise, running, cycling. The inward limit is that the foot supports, foot support shaft do not interfere with each other as they pass each other during use. This embodiment allows for near zero midline stride, stride width between the user's feet during exercise.

[0054] Configuring with a non-centered frame but with left and right frame structures allows for a linkage system of foot support shaft cooperating foot support members to vary in width during exercise with a step width > 0. The step width SW can vary inward > 0 (0 being the midline) and outward from the midline allowing the user to vary their stride, step width, step length and stride length during running, cycling according to individual biomechanical preference.

[0055] In preferred embodiments, the running, cycling device has a typical drive resistance system arrangement such as those found on typical stationary bicycles, elliptical machines, etc. Thus, the first set of left and right linkages (e.g. crank arms) are fixed at one end which is connected to a mechanism which is also an axis and cooperates with the rotational drive system. When using linkages such as crank disks, crank pulleys as the first set of linkages, these are fixed and connected from their center to the mechanism which is also an axis and cooperates with the rotational drive system.

[0056] This first set of left and right linkages (e.g. crank arms) or when using crank disks, crank pulleys, the first set of left and right linkages are fixed relative to each other at 180 degrees from the point of connection between the first and second set of left and right linkages, thus when one crank arm or point of connection between the first and second linkages is at the 12:00 o'clock position, the other is at the 6:00 o'clock position and vice versa. This pattern is fixed throughout the 360 degree rotation just like the first set of crank arms in a standard bicycle.

[0057] The hour hand of a clock is used to describe the positioning of the left and right crank arms or relative position of the point of connection between the first and second linkages as follows: For example: Left first crank arm position and point of connection between first and second left linkages Right first crank arm position and point of connection between first and second right linkages 12 straight up 6 straight down 3 straight forward horizontal 9 straight backward horizontal 6 straight down 12 straight up 9 straight back horizontal 3 straight forward horizontal

[0058] The second set of left and right crank arms can be connected at the position where the first set of left and right crank arms normally connect to the pedals of a conventional fixed frame bicycle or a bicycle. When the first link member crank arm and / or the connection point between the first link member and the second link member approaches the 12:00 o'clock direction, the second crank arm connects with the first crank arm or crank disc, the crank pulley can swing, move freely forward and upward, extend forward, without any resistance other than the weight of the foot support and the second crank arm itself.

[0059] The connection pivot point of the second set of crank arms to the first set of crank arms can be fixed or adjustable in distance along the first crank arm relative to the connection of the first set of crank arms to the frame axis. The adjustable distance can be adjusted to accommodate different body sizes of users and based on the preferences of the users. When the connection point of the first set of crank arms and the second crank arm rotates around the axis of rotation together with the frame, it maintains a consistent distance from the spool between the first set of crank arms and the frame.

[0060] The connection of the foot support can be fixed or adjustable in distance along the second crank arm relative to the connection of the second crank arm to the first crank arm. The adjustable distance can be adjusted to accommodate different body sizes of users and based on the preferences of the users. When the second crank arm swings, rotates around the pivot point of the connection of the second crank arm to the first crank arm, the connection point of the foot support maintains a consistent distance from the pivot point of the connection between the second crank arm and the first crank arm.

[0061] The second set of crank arms can move freely, rotate unidirectionally around the pivot point of the connection between the second set of crank arms and the first set of crank arms, and allow a large parameter of variable motion. It facilitates the free rotation, forward, upward extension of the foot support motion path. This unidirectional forward motion allows the second crank arm set to rotate, swing, extend forward, cantilever and extend the motion of the running cycle when it reaches, extends upward, outward to a point until the force arm acting on the second crank arm set is downward. When the extension of the forward swing motion reaches a peak and the motion and force are downward, the swing second crank arm, pivot connection is fixed, has a clutch function, allowing the second crank arm to extend and allowing the stride, step length and hip, knee to change upward relative to the pivot point of the connection of the second crank arm and the first crank arm. Therefore, the user can freely issue motion by his own strength and biomechanical form. The amplitude of extension is determined by the user's own motion input and physical activity, and is within the external limit range of the adjusted crank arm physical size.

[0062] The swing amplitude of the second crank arm is dependent on the user's own movement strength, power, running, cycling action skill, and the user's extension and elongation of the stride during movement by knee drive, hip flexion, thigh lift, and movement speed. The entire swing rotation process of the second crank arm can be described as swing phases, such as: initial swing phase, mid-early drive swing phase, peak swing drive upward phase, hip peak upward phase, late swing phase (downward), knee and hip extension phase, bottom downward phase, and then repeat into the initial swing phase. The second crank arm can swing forward until it is at the descending point. When descending, the second swing crank arm stops, the clutch, brake, lock prevents backward swing, thereby ensuring the fixed extension crank arm position, increasing and enhancing the user's stride length, and allowing the user to freely and individually select the preferred stride and variable travel path.

[0063] For example, when the left side second crank arm with the pivot point connection of the first crank arm rotates upwardly left side through the 12:00 o'clock direction and downwardly through the 10:30 position, complete swing extension will occur. Likewise, when the right side second crank arm with the pivot point connection of the first crank arm rotates upwardly right side through the 12:00 o'clock direction and downwardly through the 1:30 o'clock direction, such complete swing extension will also occur.

[0064] The user's foot movement pattern can be freely determined by the user when exercising on the device. They can simulate fast running movements or slower running movements. They can simulate high knee action or low knee action. They can move their feet inward or outward, making the distance between their feet closer or further apart. They can simulate larger or smaller step and stride actions.

[0065] The user can take large steps, long steps, or small steps, short steps, and adjust the width between their feet while moving, all depending on the speed and strength the user puts into the movement according to their personal biomechanical preferences.

Implementation of Preferred Embodiments

[0066] Figure 1A preferred embodiment of an exercise device, generally indicated as exercise device 1, is schematically shown, comprising a frame 2 and a pivot 11. There can be a left side linkage system and a right side linkage system. The frame 2 can be located between the linkage system configurations. One end of a first linkage member can be conceived as a crank arm 13A, which end is connected to the pivot 11, and the other end of the same first linkage member (e.g. crank arm 13A), i.e. the end away from the end connected to the pivot 11, is a connection 17 to a second linkage member 29, preferably designed as a second crank arm 29. In the following, for ease of description, the first linkage member 13 and the second linkage member 29 are referred to as first crank arm 13 and second crank arm 29, respectively. A one-way device can cooperate with the connection 17 of the second linkage member (e.g. crank arm 29) and the first linkage member (e.g. crank arm 13A). A support surface 35, which can be designed as a foot support 35, can be attached to the second crank arm 29, and preferably close to the second crank arm 29 or at the distal end of the second crank arm 29 from the connection 17. The second crank arm 29 swings, rotates in one direction, while rotation in the other direction is generally not possible. The left side first crank arm 13AL rotates counterclockwise with the pivot 11, while the left side second crank arm 29L swings, rotates clockwise one-way about the connection 17L pivot point. The right side first crank arm 13AR rotates clockwise with the pivot 11, while the right side second crank arm 29R swings, rotates counterclockwise one-way about the connection 17R pivot point. The left side first crank arm 13AL and the right side first crank arm 13AR can be connected and / or configured such that they rotate simultaneously in the same direction, preferably with the same angular velocity, during operation (i.e. daily exercise) of the exercise device 1. Generally, the left side first crank arm 13AL and the right side first crank arm 13AR are both coupled to the pivot 11 such that they have a fixed angular distance from each other. In detail, the connection points 17L, 17R have a fixed angular distance from each other, preferably an angular distance of 180°. Since the left side linkage and the right side linkage are located on opposite sides of the frame 2 and face away from each other (see Figure 1 ), the left side first crank arm 13AL and the right side first crank arm 13AR are considered to rotate counterclockwise and clockwise, respectively. In other words, Figure 1 the left side first crank arm 13AL can be considered to be in front of an imaginary clock defining a clockwise direction, while Figure 1 the right side first crank arm 13AR is located behind the imaginary clock. When viewed from a fixed position (e.g. the viewing direction of Figure 1 ), the crank arms 13AR and 13AR can be considered to rotate in the same direction. Although reference is made to a left side first crank arm 13AL and a right side first crank arm 13AR, these features are optional and can be replaced by other members, e.g. a crank disc can be used instead (see e.g. Figure 2A) or crank pulley. In the following, the more general terms: left first link member and right first link member, or more generally first link member 13, will sometimes be used instead of left crank arm and right crank arm. The first link member 13 can be a crank arm 13A, extension, component, disc 13B, piece or piece that allows connection from the distal end of the rotating shaft 11 that maintains a consistent distance from the rotating shaft when rotating, running, encircling around the axis. The link member linkage can work in conjunction with the rotating shaft 11 in the drive system through link members 13L and 13R, optionally including components 4 (pulley, sprocket, gear, etc.), connecting members 5 (belt, chain, etc.), and optionally including resistance devices 10. Resistance devices 10 can be configured and work in conjunction with one or more components such as a flywheel, friction pad, belt, alternator, magnet, eddy current brake, a mixture of these components, etc. In addition, the installation of the handle 3 can also be considered in the exercise device 1.

[0067] Figures 1A to 1A7 、 Figure 1B 、 Figures 1B1 to 1B21 、 Figure 1C and Figure 1E The preferred embodiment shows an example of the motion that can be achieved. These figures show the link member 13, the crank arm 13A connected to the rotating shaft 11 rotating counterclockwise. At the same time, the link member connected to the crank arm 13A, the crank arm 29 moves unidirectionally, swings in the clockwise direction upward and forward.

[0068] The user can place his feet on the foot support 35. The foot support can be connected to the crank arm 29 through the connecting part 33, and the distance between the connecting part 17 and the crank arm 29 can be adjusted at multiple positions on the crank arm 29, for example, can be fixed at different positions on the crank arm 29. These figures show the motion path that the user's feet can reach when the foot support 35 is connected at the connecting part 33 on the crank arm 29. The actual foot support 35 is not shown in these figures, but the symbol connecting part 33 indicates the position of the foot support connected to the crank arm 29, and shows the path that the user's feet supported on the foot support can travel based on biomechanics and the forces generated and output by the user when running and cycling.

[0069] Figures 1A1 to 1A7 Twenty-four static pictures are shown, which are arranged in sequence to describe in detail the relative configuration of the first link member 13 and the second link member 29 during the motion. If you quickly scroll down when viewing these figures, it can help to show and observe the motion pattern of the interconnected link members.

[0070] Figure 1B 、 Figures 1B1 to 1B21Several still images are displayed, arranged in sequence, detailing the relative configuration of the first crank arm 13 and the second crank arm 29 during movement. The foot support can connect to any of the several connection points 33 shown on the second crank arm 29. In this diagram, arrows indicate the paths of the connection points 33 to which the foot support can connect, i.e., the positions on the second crank arm 29 where the foot support can connect, and the movement paths of the second and first crank arms during a full rotation, depending on their configuration. Scrolling quickly down while viewing these diagrams reveals the movement patterns along the arrow-marked paths, which helps to show the reachable movement paths of the connection points 33 where the foot support connects to the second crank arm 29. The marked arrow paths show the movement that can be achieved and generated by the user's force through the foot supported on the foot support when connected at the connection points 33 during the running cycle. Figure 1B , Figures 1B1 to 1B21 As shown in the multiple axial views of the first crank arm 13 and the second crank arm 29, the foot support shaft (i.e. Figure 1 The foot support shafts 37L and 37R) are connected to the second crank arm 29 via a connecting portion 33 (i.e., Figure 1 The connecting parts 33L and 33R describe a complex motion different from circular motion, which can be viewed as a shape similar to a comma or the Chinese yin-yang symbol. On the other hand, the second crank arm 29 is attached to the connection point 17 of the first crank arm (i.e., Figure 1 The connecting parts 17L and 17R in the middle perform circular motion.

[0071] Figure 1C The diagram shows the first link member 13 and the second link member 29 fully extended forward and upward, and shows the available travel path depending on the position of the connection 33 where the foot support can be connected to the second crank arm.

[0072] Figure 1E The diagram shows the path of the accessible travel area depending on the input and force generated by the user while running or cycling, and the connection 33 of the second crank arm 29, which connects to the first crank arm 13 at the distal end.

[0073] Figure 2A preferred embodiment of a linkage system with foot supports is shown schematically. A first set of crank arms 13AL and 13AR are set 180 degrees apart from each other and connected to a pivot 11 which is connected to a drive system component (e.g. a pulley or sprocket or the like) 4 located between the first set of crank arms 13AL and 13AR. A second set of crank arms 29L and 29R are connected to the first set of crank arms 13AL and 13AR at connection points 17L and 17R respectively, which are distal from the pivot 11 to which the first set of crank arms are connected. The left side second crank arm 29L swings or rotates unidirectionally in a clockwise direction about the connection 17L. The right side second crank arm 29R swings or rotates unidirectionally in a counter-clockwise direction about the connection 17R. As mentioned above, the left side second crank arm 29L and the right side second crank arm 29R can be seen to rotate or pivot in the same direction when viewed from one viewing direction, but during operation of the exercise device 1, i.e. during an exercise, they rotate in the opposite direction to the left side first crank arm 13AL and the right side first crank arm 13AR. At least one or both of the second crank arms 29L, 29R can rotate or pivot independently of the rotation of the first linkage members 13L, 13R depending on the preference of the user and / or the exercise program. The only restriction on the rotation of the second linkage members 29L, 29R can be unidirectional rotation as mentioned above.

[0074] Now referring to the single element first link member 13, the connection 17, the second link member 29, but it is clear that these elements can also refer to the left side elements as well as the right side elements. The link member 13 can be referred to as a first link member and the link member 19 can be referred to as a second link member. The first link member 13 can be configured to rotate, preferably 360°, about the rotation axis 11 during one exercise cycle. The second link member 29 can be configured to rotate unidirectionally about the connection 17 for 360°. However, depending on the user's preference and exercise habits, when the first link member 13 rotates 360° relative to the rotation axis 11 in one complete rotation cycle (e.g., one cycle), the second link member can rotate more or less than 180°, more or less than 165°, more or less than 150°, more or less than 135°, more or less than 120°, or more or less than 100° relative to the axis of the connection point 17 during the complete rotation of the first link member 13, where the angle of rotation can be determined from any starting point of the second link member 29, which starting point is defined as 0°. The rotational movement of the second link member can also be described as a pivotal movement relative to the connection point 17. The rotation axis 11 can be or include a wheel axle, sometimes referred to as the rotation axis 11. The connection 17 can be referred to as a connection member 17. The connection member 17 / connection point 17 is located at the first link member 13 away from the rotation axis 11, for example at a first end of the first link member 13 opposite a second end of the first link member 13, which second end is connected to the rotation axis 11. The connection member 17 can be provided and / or attached at a first end of the second link member 19 opposite a second end of the second link member 19, which can be connected to the foot support shaft 37.

[0075] The unidirectional rotation device of the present application can be configured to allow the second link member 29 to rotate or pivot only in one direction, i.e., in the opposite direction relative to the direction of rotation of the first link member 13 relative to the rotation axis 11.

[0076] Furthermore, the foot support shafts 37L and 37R can be connected with the distal crank arms 29L and 29R at the connection points 33L and 33R, i.e., at a certain radial, longitudinal distance from the connection points 17L and 17R. The distance can be the same for both foot support shafts 37L, 37R. The foot supports 35L and 35R are attached to and cooperate with the foot support shafts 37L and 37R, which can rotate and move inwardly or outwardly when the link crank arm system rotates about the rotation axis 11, thereby adjusting the width between the user's feet. The rotation of the foot supports 35 about the foot support shafts 37 can be independent of the rotation or pivotal movement of the second link member 29 about the axis defined by the connection member 17, and / or independent of the rotation of the first link member 13 about the rotation axis 11. This can be done by the user's natural biomechanical movements of the body while running or cycling (seeFigure 21 ). The adjustable foot support 35 can also be manually adjusted by the user laterally along the foot support shaft 37 to the desired width between the feet prior to exercising (see Figure 21 ). The foot support can be fixed and not move laterally, regardless of its illustration. The ability of the foot support to move laterally during exercise is not an essential feature of the invention, but an additional benefit.

[0077] Figure 2A The embodiment in Fig. 1 1 shows that the first set of link members, e.g. the crank arms, can be interchangeable with the crank disc and the crank pulley. As shown, the first link members are 13CL and 13BR. Used as Figure 1 The pulleys or sprockets etc. that are part of the drive system in Fig. 1 1 are classified as components 4, but when there is a crank pulley with a dual purpose, i.e. simultaneously acting as one of the first link members as well as a pulley in the drive system, then it is classified as 13C, and can be designated L or R according to which side it is configured. In some cases, two crank pulleys can be used and configured on the left as well as the right side. The second set of link members, e.g. the crank arms 29L and 29R, are connected to the first set of link members, the crank pulley 13CL and the crank disc 13BR, at connection points 17L and 17R distal to the rotation axis 1 1 of the first link member connection. The connection points 17L and 17R are positioned 180 degrees relative to each other. The left second crank arm 29L swings, rotates, clockwise around the connection point 17L in one direction. The right second crank arm 29R swings, rotates, counterclockwise around the connection point 17R in one direction. As mentioned above, the right second crank arm 29R and the left second crank arm 29L rotate in the same direction in one direction when viewed from the same viewing direction. They can rotate independently of each other, since they are not rigidly coupled together.

[0078] In addition, the foot support shafts 37L and 37R connect the connection parts 33L and 33R with the crank arms 29L and 29R distal to the connection parts 17L and 17R. The foot supports 35L and 35R, which cooperate with the foot support shafts 37L and 37R and are attached to them, can rotate and can move laterally, as shown in Figure 21 and Figure 21A .

[0079] Figure 3 It shows the swing, also called the second link member or crank arm 29. It also shows a close-up of the connection part 33 to which the foot support shaft 37 can be connected. The blind hole area 19 can be configured and / or cooperate with a one-way device, preferably a one-way clutch. Such a configuration can cooperate with the connection studs, shaft connectors, shown in Figure 5 .

[0080] In addition to Figure 4 , the foot support shafts 37L and 37R can be configured to be connected to the connection parts 33L and 33R, respectively, in a way that they can rotate and move laterally, as shown in Figure 3The drilled out (annular) blind hole region 19 is shown. The annular hole enables the central portion 21 to act as an insert 21 within the configuration of the one way device as well as the angular load device. This configuration is able to work in conjunction with Figure 6 The connecting tube, tube shaft connector is shown working in conjunction.

[0081] Figure 7 , Figure 7A and Figure 9 further expand on the contents of Figure 3 and show the assembled configuration of the second swing crank arm 29 as well as the one way device 23, stud 17S configuration within the drilled out blind hole region 19 of the swing crank arm 29. The one way device 23 or one way rotation device 23 is attached to the outer region of the stud 17S (connector stud) and is connected to the inside of the outer wall of the drilled out blind hole region 19. Figure 11 Further showing the above configuration and incorporating the first crank arm 13A more completely. In addition, Figure 11 Also shown is the location where the stud 17S can connect with the holes 15L and 15R of the crank arm 13.

[0082] Figure 8 , Figure 8A and Figure 10 further expand on the contents of Figure 4 and show the assembled configuration of the second swing crank arm 29 as well as the one way device 23, angular load device 25, connecting portion 17T (tube) configuration with the drilled out blind hole region 19 and the central portion 21 of the crank arm 29. The one way device 23 is attached to the outer region of the connecting portion 17T (connector stud) and is connected to the inside of the outer wall of the drilled out blind hole region 19. The angular load device is attached to the inside of the connecting portion 17T (connecting tube) and is connected to the outside of the annular hole stud 21. Figure 12 Further showing the above configuration and incorporating the first crank arm 13 more completely. In addition, Figure 12 Also shown is the location where the connecting portion 17T can connect with the holes 15L and 15R of the first crank arm 13.

[0083] Figure 13 Also shown is the application in the preferred embodiment assembled configuration of the single drive with the left and right configuration of the first stationary crank arm and the second swing crank arm in Figure 1 as well as previously in Figure 11 and Figure 12The first crank arms 13R and 13L are connected to the axle 11 and can be fixed and positioned 180 degrees relative to each other. Between the left and right first crank arms can be configured the components of the drive system 4, which can include or consist of pulleys, sprockets, etc. When the left and right first crank arms rotate, they drive, rotate the aforementioned components 4. The holes 15L and 15R, which are connected to the first set of crank arms, are in different allowed positions, a connecting part 17T. The connecting part 17T connects the first set of crank arms with the second set of swing crank arms 29. The holes 15L and 15R allow the distance of the connecting part 17T from the second set of swing crank arms to be adjustable in the distal direction, i.e. radially, longitudinally from the axle 11 and in the radial, longitudinal direction of the first set of crank arms 13. The right first crank arm 13R and the second swing crank arm 29R are connected to each other through the configuration of the connecting part 17T, showing the right first crank arm 13R moving and rotating clockwise, while the right swing second crank arm 29R rotates and swings counterclockwise as shown. Likewise, through the configuration of the connecting part 17T, the left first crank arm 13L moves and rotates counterclockwise, while the left swing second crank arm 29L rotates and swings clockwise as shown. The foot support 35, preferably a pedal, is not shown in Figure 13 , will be configured on the foot support axle 37 and connected to the second crank arm 29 through the connecting part 33, opposite the connecting part 17T.

[0084] Figure 14 Further expanding Figure 13 , an embodiment of the drive system, which can be part of the exercise device 1, is shown. The drive system is shown as follows, demonstrating a first drive element 4 (e.g. a single pulley, sprocket, gear, etc.) configured with a connecting member 5 (e.g. a belt, chain, etc.) connecting the first drive element 4 with a second drive element 9 (e.g. a pulley, sprocket, gear, etc.) in turn moving, rotating, turning, etc. a component of a connected resistance device 10 (e.g. a flywheel 10), which can also be an eddy current brake, a magnetic resistance, a wheel, etc. providing resistance.

[0085] Figure 15 Further expanding Figure 14 , but showing the addition of an additional second pulley, sprocket, gear, etc. with an offset 4B, allowing the further configuration of an additional connecting member 5B (pulley, chain, etc.) in turn driving the second drive element 9 (pulley, sprocket, gear, etc.) to rotate, turn a flywheel 10, which can also be an eddy current brake, a magnetic resistance, a wheel, etc. providing resistance.

[0086] Figure 16Another embodiment of the exercise device 1 is shown schematically, a running cycling version, but without any frame and / or components between the left linkage member configuration and the right linkage member configuration. This frame 2D has a left frame 2DL with an axle 11DL and a right frame 2DR with an axle 11DR. There are left and right linkage systems which can have corresponding elements. The frame 2D with left frame 2DL and right frame 2DR is outside of the linkage system configuration. One end of a first crank arm 13D is connected to the axle 11D and the other end of the same first crank arm 13 is connected to the connection 17DL and 17DR of the second crank arm 29DL and 29DR away from the end connected to the axle 11D. A one-way device can be coordinated with the second crank arm 29DL and 29DR and 17DL and 17DR of the first crank arm 13D. A foot support 35 can be configured with a foot support axle 37L and 37R which can be attached to the connection 33L and 33R of the distal end of the second crank arm 29DL and 29DR and preferably close to or at the distal end from 17DL and 17DR. The foot support preferably pedal can rotate and can move laterally along the axle 37D. The second crank arm 29DL and 29DR swings, rotates unidirectionally. The left first crank arm 13ADL rotates clockwise with the axle 11DL while the left second crank arm 29DL swings, rotates unidirectionally counterclockwise about the pivot point of the connection 17DL. The right first crank arm 13DAR rotates counterclockwise with the axle 11DR while the right second crank arm 29DR swings, rotates unidirectionally clockwise about the pivot point of the connection 17DR. The first linkage member 13D can be a crank arm 13DA, an extension, a component, a plate 13DB, a pulley 13DC, one or more components which allow the connection away from the axle 11D to maintain a consistent distance from the axle 11D as it rotates, revolves, orbits around the axle 11D. The linkage member linkage system is connected to the axle 11DL and 11DR through the linkage member 13DAL and 13DAR respectively and coordinated with the pulley 4DL and 4DR, resistance device 10 in the drive system. The resistance device 10 in this application can be configured and coordinated with one or more components, elements such as a flywheel, a friction pad, a belt, a generator, a magnet, an eddy current brake, etc., or a mixture of these components.

[0087] Figure 17 、 Figure 18 and Figure 19 are expanded and depicted in more detail Figure 16Embodiments of different drive system configurations are depicted. These drive systems are shown as double pulley, sprocket, gear, etc. systems. When the left and right side link members engage and rotate with the axle shafts 11DL and 11DR and work in conjunction with the drive system pulleys 4DL and 4DR (pulley, sprocket, gear, etc.) of the drive system, the connecting members 5DL and 5DR (belt, chain, etc.) connect and attach to the components 4CL and 4CR (pulley, sprocket, gear, etc.) and rotate with the axle shaft 6, which in turn rotates the other component 4C (pulley, sprocket, gear, etc.). The component 4C is connected to the connecting member 5B (belt, chain, gear, etc.), which is also connected to the second drive element 9 (pulley, sprocket, gear, etc.), which in turn drives the resistance device 10. The resistance device 10 can be configured and work in conjunction with one or more components such as a flywheel, friction pad, belt, alternator, magnet, eddy current brake, and hybrids thereof.

[0088] Figure 18 A similar version of the drive system configuration in Figure 17 is depicted, but the axle shaft 6B is directly connected to and rotates the resistance device 10.

[0089] Figure 19 Very similar to Figure 18 , but the axle shaft 6C is positioned with the resistance device 10, which is located at the far left of the drive system configuration. The resistance device 10 can also be located at the far right of the drive system configuration.

[0090] Figure 20 An embodiment of a drive system is depicted, configured with the first drive element 4, connecting member 5, second drive element 9 as previously described, in front of the resistance device 10B. In this configuration, the resistance device 10B can be the resistance device 10 mentioned previously, or it can be a wheel, which can be placed on a surface such as the ground. The resistance device 10B (wheel) can provide movement along the ground.

[0091] Figure 21 An embodiment of the foot support 35 as a pedal is shown, which can move laterally, i.e. in the axial direction, on the foot support shaft 37 when the user exercises. As shown, the foot support can be positioned in a range from inside to outside, and can be seen in the illustration.
