Description of the preferred embodiment

Referring now to Figures 1-14, the present invention features a machine for use with, for example, a training device, such as a stationary bicycle system, a novel planetary gear system for use, and a rolling reversing lateral motion system. However, the system of the present invention is not limited to training equipment (e.g., stationary bicycle systems, rotary exercise machines, rowing exercise machines, abdominal trainers, etc.). The novel planetary gear system of the present invention allows the crank and flywheel to be integrated into a single assembly.

Planetary gear system

As shown in Figures 1-4, the planetary gear system 100 includes a flywheel 105. The flywheel 105 can be similar to a standard flywheel used in stationary bicycles known in the art as one of ordinary skill in the art. The flywheel 105 is generally circular in shape (e.g., a flat circle and, for example, has an outer rim, a center 106, a first surface, and a second surface). In some embodiments, the flywheel also acts as a resistance device when a friction brake block is applied to the outer surface of the rotating flywheel. This provides the user with a greater resistance to the purpose of fitness for changes and higher levels of strength.

The flywheel 105 can be constructed in a variety of sizes and weights. For example, in certain embodiments, the flywheel 105 weighs between about 5 and 10 pounds. In certain embodiments, the flywheel 105 weighs between about 10 and 15 pounds. In certain embodiments, the flywheel 105 weighs between about 15 and 20 pounds. In certain embodiments, the flywheel 105 weighs between about 20 and 25 pounds. In certain embodiments, the flywheel 105 weighs between about 25 and 30 pounds. In certain embodiments, the flywheel 105 weighs between about 30 and 35 pounds. In certain embodiments, the flywheel 105 weighs between about 35 and 40 pounds. In certain embodiments, the flywheel 105 weighs between about 40 and 45 pounds. In certain embodiments, the flywheel 105 weighs between about 45 and 50 pounds. In certain embodiments, the flywheel 105 weighs between about 50 and 55 pounds. In certain embodiments, the flywheel 105 weighs between about 55 and 60 pounds. In certain embodiments, the flywheel 105 weighs between about 60 and 65 pounds. In certain embodiments, the flywheel 105 weighs more than about 65 pounds. The flywheel weight can vary from 5 to 65 pounds, depending on the gear ratio selected and the preferred inertia "feel" during the design process. The invention is not limited to the aforementioned flywheel weights.

In some embodiments, the diameter of the flywheel 105 is between about 4 and 8 inches. In some embodiments, the diameter of the flywheel 105 is between about 8 and 10 inches. In certain embodiments, the diameter of the flywheel 105 is between about 10 and 12 inches. In some embodiments, the diameter of the flywheel 105 is between about 12 and 16 inches. In some embodiments, the diameter of the flywheel 105 is between about 16 and 20 inches. In some embodiments, the diameter of the flywheel 105 is greater than 20 inches. In some embodiments, the flywheel 105 has a diameter of less than 8 inches. The flywheel size limitation can vary with the overall design of the training bicycle. The invention is not limited to the aforementioned dimensions of the flywheel 105.

Passing through the center 106 of the flywheel 105 is a shaft 110. The shaft 110 can be rotated independently of the flywheel 105 (eg, the shaft 110 and the flywheel 105 are not fixedly attached). The shaft 110 has a first end 111 and a second end 112. The first end 111 of the shaft 110 protrudes from the first surface of the flywheel 105 and the second end 112 of the shaft 110 is covered by the flywheel 105. The second surface protrudes. A first crank 120a is disposed on the first end 111 of the shaft 110, and a second crank 120b is disposed on the second end 112 of the shaft 110.

A sun gear 115 is disposed (not fixedly) on the shaft. The sun gear 115 is fixedly attached to the flywheel 105. For example, the sun gear 115 has a center aligned with the center 106 of the flywheel 105, and the shaft 110 passes through the center 106 of the flywheel 105 and the center of the sun gear 115. Similar to the flywheel 105, the sun gear 115 rotates independently of the shaft 110 (e.g., because the flywheel 105 and the sun gear 115 are fixedly attached, the two rotate together).

In some embodiments, a housing 130 is disposed on the shaft 110 and between the flywheel 105 and the second crank 120b (or the first crank 120a). The shaft 110 is not fixedly attached to the housing; the shaft 110 rotates independently of the housing 130. For example, the housing 130 remains stationary and the shaft 110 rotates relative to the housing 130 in a first direction and/or a second direction.

A planet carrier 140 is fixedly attached to (and housed in) the shaft 110. The planet carrier 140 has a center and the shaft 110 passes through its center. The shaft 110 rotates in the first direction to rotate the planet carrier in the first direction, and the shaft 110 rotates in the second direction to rotate the planet carrier 140 in the second direction. The planet carrier 140 can be constructed in a variety of different shapes. For example, in some embodiments, the planet carrier 140 has a generally triangular shape (see, for example, Figure 1). In some embodiments, the planet carrier has a generally square/rectangular shape. In some embodiments, the planet carrier has a generally pentagonal shape. In some embodiments, the planet carrier has a generally circular shape. The planetary carrier 140 is not limited to the aforementioned shape.

A ring gear 160 is housed in the housing 130 and fixedly attached to the housing 130. In some embodiments, the ring gear 160 is positioned around the planet carrier 140, although the invention is not limited to this configuration. For example, in some embodiments, the ring gear 160 is positioned around all or a portion of the majority of the planet gears 150 and the planet gears 150 are disposed on the planet carrier 140.

The system 100 of the present invention further includes a plurality of planet gears 150 disposed on the planet carrier 140. In certain embodiments, the system 100 includes a planet gear 150. In certain embodiments, the system 100 includes two planet gears 150. In certain embodiments, the system 100 includes three planet gears 150. In certain embodiments, the system 100 includes four planet gears 150. In certain embodiments, the system 100 includes five planet gears 150. In certain embodiments, the system 100 includes six planet gears 150. In certain embodiments, the system 100 includes seven planet gears 150. In certain embodiments, the system 100 includes eight planet gears 150. In certain embodiments, the system 100 includes nine planet gears 150. In certain embodiments, the system 100 includes ten planet gears 150. In some embodiments, the system 100 includes more than ten planet gears 150 (eg, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, ten Eight, nineteen, twenty, more than twenty, etc.).

In certain embodiments, the system 100 includes three planet gears 150. In some embodiments, a first planet gear 150a is rotatably attached to a first position of the planet carrier 140 (eg, through a first planet gear shaft 158a), a second planet gear 150b Is rotatably attached to a second position of the planet carrier 140 (eg, through a second planet gear shaft 158b), and a third planet gear 150c is coupled (eg, through a third planet gear shaft 158c) ) is rotatably attached to a third position of the planet carrier 140. The planet gears 150 are not fixedly attached to the planet carrier 140 and are rotatable independently of the planet carrier 140. For example, the planet gears 150 are rotatable relative to the planet carrier 140 about its respective planet gear shaft 158.

The planet gears 150 can be disposed on the planet carrier 140 in any configuration. In some embodiments, the planet gears 150 are asymmetrically disposed on the planet carrier 140. In some embodiments, the planet gears 150 are symmetrically disposed and spaced apart on the planet carrier 140. For example, the first position on the planet carrier 140 is equidistant from the second position and the third position on the planet carrier 140, and the second position on the planet carrier 140 is at The first position and the third position on the planet carrier 140 are equidistant (see, for example, Figure 1). The invention is not limited in any way to this configuration.

In some embodiments, each of the planet gears 150 includes a small planet gear 151 and the asteroid gear 151 is fixed to a large planet gear 152. However, the planetary gears 150 are not limited to this composite configuration. Each of the asteroid gears 151 and each of the major planet gears 152 has a center, and the centers of the asteroid gears 151 are aligned with the centers of the large planet gears 152. The planet gear shafts 158 pass through the centers of their respective asteroid gears 151 and large planet gears 152. The asteroid gears 151 are smaller than their respective large planet gears 152, and thus each of the asteroid gears 151 has a diameter smaller than the diameter of each of the large planet gears 152. In some embodiments, the composite gears may be replaced by a plurality of single gears, such as a plurality of single gears that engage or mesh with the sun gear and/or the ring gear.

As shown in Fig. 1, each of the asteroid gears 151 engages the ring gear 160 (the inner surface of the ring gear 160) and the major planetary gears 152 engage the sun gear 115 (the outer surface of the sun gear 115). In some embodiments, each of the large planet gears 152 has a set of teeth disposed on an outer edge (outer surface) thereof, and the set of teeth is engaged on one of the outer edges (outer surfaces) of the sun gear 115. Group of teeth. In some embodiments, each of the asteroid gears 151 has a set of teeth disposed on an outer edge (outer surface) and the set of teeth is engaged on one of the outer edges (outer surfaces) of the ring gear 160 Group of teeth. The present invention is not limited to the engagement of the gears through a plurality of teeth; for example, in some embodiments, the large planet gears 152 frictionally engage the sun gears, the pinion gears 151 engaging the ring gears by friction.

When the shaft 110 (transmits through the cranks 120) rotates in a first direction, the planet carrier 140 also rotates in the first direction (eg, the planet carrier 140 is fixedly attached to the shaft 110) on). The planetary carrier 140 rotates in the first direction to rotate the respective planetary gears 151 in the second direction (opposite the first direction) in the ring gear 160 and the major planetary gears 152 in the second direction. (opposite the first direction) rotates around/around the sun gear 115. The asteroid gears 151 and the large planet gears 152 rotate in the second direction to rotate the sun gear 115 and the flywheel 105 together in the first direction (the flywheel 105 rotates in the same direction as the cranks 120) .

In some embodiments, the flywheel 105 rotates about the shaft 110 through a plurality of first ball bearings 180a (see, for example, FIG. 4). In some embodiments, the shaft 110 is rotated within the housing 130 through a plurality of second ball bearings 180b (see, for example, FIG. 4).

In some embodiments, a friction brake block is mounted to the frame or housing. The friction brake block can be pressed against the flywheel by a user adjustable force to provide braking resistance to the system, allowing the user to increase and adjust the resistance to the system and to change the force required to rotate the pedals. The brake blocks or the brake blocks may be made of a suitable material such as felt or leather to provide a long-wearing friction brake device for any or most of the surface of the flywheel. The brake block or the brake blocks are not limited to this configuration.

In some embodiments, a magnetic field can be applied to a metal flywheel to induce a frictional resistance through the eddy current effect to achieve the same goal. The magnetic field can be generated by a permanent magnet, or an electromagnet, or other type of magnet. These magnets are well known to those of ordinary skill in the art. The amount of resistance can be varied by adjusting the strength of the magnetic field and/or the proximity of the magnetic field to the surface or majority of the surface of the flywheel.

As shown in Figures 10-14, in some embodiments, the planet gears 150 are not composite gears (composite gears, such as combinations of the large planet gears 152 and the asteroid gears 151 as described above). As described above, the sun gear 115 is fixedly attached to the flywheel 105, and the planetary carrier 140 is fixed to the shaft 110. One or more planet gears 150 (eg, two, three, four, five, six, etc.) are disposed on the planet carrier 140 (eg, through a majority of planet gear shafts 158). The planet gears 150 are rotatable independently of the planet carrier 140. The ring gear 160 is disposed in the housing 130 surrounding the planet gears 150. The ring gear 160 engages the outer surfaces of the planet gears 150. The planet gears 150 are positioned such that their outer surfaces engage the sun gear 115 (see, for example, Figure 11). When the cranks 120 and the shaft 110 are rotated in a first direction, the planet carrier 140 is then rotated in the first direction. This causes the planet gears 150 to rotate within the ring gear 160 in the second direction. The planetary gears 150 drive the sun gear 115 and the flywheel 105 to rotate in the first direction by the rotation in the second direction.

System 100 of the present invention provides a rate increase ratio. As used herein, the term "speed increase ratio" means that the number of revolutions of the flywheel 105 is compared to the number of revolutions of the cranks 120. For example, a speed increase ratio of 11:1 indicates that the flywheel 105 rotates 11 times for each rotation of the cranks 120.

In certain embodiments, the rate of increase in speed is between about 1:1 and about 20:1. In some embodiments, the rate of increase in speed is at least about 1:1. In some embodiments, the rate of increase in speed is about 11:1. In some embodiments, the speed increase ratio is approximately 2:1. In some embodiments, the rate of increase in speed is about 5:1. In some embodiments, the speed increase ratio is approximately 8:1. In some embodiments, the rate of increase in speed is about 10:1. In some embodiments, the speed increase ratio is approximately 12:1. In some embodiments, the rate of increase in speed is approximately 15:1. In some embodiments, the rate of increase in speed is approximately 20:1. In certain embodiments, the rate of increase in speed is at least about 20:1.

Generally, the system 100 of the present invention is used in a training device, such as a stationary bicycle system. As shown in Figure 5, the system is integrated into a bicycle frame 210. The housing 130 is fixed to the frame 210 (or in the frame 210) to provide support and resistance, and the cranks and shafts 110 are rotatable relative to the resistance. As in standard stationary bicycles, the bicycle system can include a handle system 220 and a seating system 230. In some embodiments, the bicycle frame 210 includes a first extension 215a adapted to support the handle system 220. In some embodiments, the bicycle frame 210 includes a second extension 215b adapted to support the seating system 230. The handle system 220 and the seating system 230 can be a variety of different configurations and systems including, but not limited to, standard handle systems and seating systems that are well known to those of ordinary skill in the art. The system of the present invention can also be used in a "slanting" type bicycle in which the user sits substantially in one of the seats or saddles behind the pedal crankset. The user sits in a seat-like configuration and the bicycle frame is designed to fit this position, and the handle, seat armrest, and other features are suitably configured.

As shown in FIG. 5, the stationary bicycle system includes a base 250 to which the bicycle frame 210 is attached. In some embodiments, the base 250 is substantially elliptical in shape, but the base 250 is not limited to this shape (for example, the shape of the base 250 may be circular, rectangular, H-shaped, I-shaped, X-shaped, etc.) . The bicycle frame 210 can include an extension 215c that is coupled to the base 250.

In certain embodiments, the ring gear 160 (eg, having a plurality of teeth on the inner diameter) may be replaced by a gear having a plurality of teeth on the outer diameter and mounted on the same shaft. The ring gear 160 is still engaged or engaged with the planet carrier 140, but on the side of the planet gear facing the shaft 110 (rather than the side opposite the shaft 110 as described above). This configuration allows the planet gears 150 to rotate in the same direction of rotation as the planet carrier 140, and the sun gear 115 rotates in the opposite direction of rotation.

In some embodiments, the planet carrier 140 is rigidly attached to a plurality of frame support members (eg, two housings 130, 130a; the two housings 130, 130a are supported by a plurality of bearings 180b), And the ring gear 160 is rigidly attached to the shaft 110. In this configuration, the planet carrier 140 is stationary and does not rotate, and thus the planet gears 150 do not rotate about the spindle shaft 110. As the cranks 120 rotate, the ring gears 160 also rotate (the ring gears 160 are fixedly attached to the shaft 110) such that the planet gears 150 can rotate about their respective planet gear shafts 158. The planetary gears 150 engaged (or meshed) with the sun gear 115 rotate the sun gear 115, and thus the flywheel 150 rotates because the flywheel 105 is fixedly attached to the sun gear 115.

Without wishing to limit the invention to any theory or mechanism, it is believed to be advantageous because the planetary gear system 100 of the present invention does not require adjustment of a chain or belt. For example, many training bicycles use a chain or a belt drive system to transmit the rotary motion of the pedals and cranks to a flywheel. Both belts and chains often require a way to adjust the center distance (the distance between the drive and the driven shaft) in order to keep the system functioning properly. A too loose belt will slip and cause a loss of transmitted energy and torque. Similarly, a too loose chain can jump, generate noise, or even completely detach the links. Conversely, if the chain or belt is too tight, it can cause premature wear and breakage. Both the belt and the chain are elongated and worn over time and after use, so that they need to be periodically adjusted during their service life. This will cost the owner time and money. Because the system 100 of the present invention does not use a belt or chain, it does not need to be adjusted for proper operation, and does not require failure for periodic maintenance or failure due to lack of maintenance. Further, due to the close characteristics of the planetary gear system 100, there is no case where the exposed external moving member is entangled or stuck as a chain drive is likely to occur.

Without wishing to limit the invention to any theory or mechanism, it is believed to be advantageous because the planetary gear system 100 of the present invention can have a higher gear ratio. For example, many training bicycles have a belt or chain drive to transmit rotational motion from the pedal crankshaft to the flywheel. The purpose of having a flywheel on a training bicycle is to increase the rotational inertia of the drive system, provide him with a sense of resistance when the user accelerates, and maintain the speed of the system when the user does not apply the pedaling force (for example, in each pedaling) The top and bottom of the trip). The physical inertia of the flywheel is determined by its weight and configuration. The inertia felt by the rider on the pedal crank is determined by the ratio of movement between the pedal crank and the flywheel (or it may be referred to as gear ratio). For a fixed weight flywheel, the higher the gear ratio, the higher the inertia felt on the pedals. Most chain-driven training bicycles are limited by the pedal crank ring size and the actual size of the flywheel link size to a gear ratio of approximately 3.25:1. At this ratio, a flywheel of approximately 45 pounds and a diameter of 20 inches must be used to comfortably simulate an acceptable pedal inertia. The planetary gear system of the present invention achieves a higher gear ratio in a smaller, tighter space. For example, when the gear ratio is 11:1, the required weight of the flywheel is only about 8 pounds and 12 inches in diameter to have the same pedal inertia feel as a chain driven bicycle having a 45 pound flywheel. This is advantageous for many things including the manufacturing cost, shipping and mobility of the bicycle.

Without wishing to limit the invention to any theory or mechanism, the planetary gear system 100 of the present invention is believed to be advantageous because the coaxial operation of the crank and flywheel is tight and there may be design freedom. For example, many training bicycles have a belt or chain drive to transmit rotational motion from the pedal crankshaft to the flywheel. The desired center distance between the pedal crankshaft and the flywheel shaft can be greater than 18 inches, making the entire transmission system with a 20 inch flywheel bulky and requiring a rigid frame to support the two bearings for both axles. By positioning the flywheel and the pedal cranks on the same shaft as in the system 100 of the present invention, the entire drive train package can be made more compact. The frame only needs to support a single set of bearings. And since there is a smaller flywheel by the higher gear ratio as described above, the entire transmission system including the crank, the transmission and the flywheel can be made in a 12 inch diameter circular space. This is an advantage because it has the freedom to design options for the vehicle's architectural form, takes up less space, and the product design can have new and different shapes.

Without wishing to limit the invention, it is believed to be advantageous because the flywheel 105 can be rotated at a greater speed. This speed and energy can be utilized as power to achieve other goals.

The system of the present invention can be constructed from a variety of materials. Examples of materials may include, but are not limited to, metals and/or metal alloys (eg, stainless steel, titanium, aluminum, carbon steel, etc.), rubber, plastic, etc., or combinations thereof.

Rolling reverse roll lateral motion system

Referring now to Figures 5-9, the present invention is also characterized by a rolling rewind lateral motion system 500. The roll-to-roll lateral motion system 500 enables lateral, side-by-side, and rolling motions that feel a natural-like motion when riding a bicycle into a corner or when standing (eg, for a sprint).

The rolling rewind lateral motion system 500 of the present invention includes a rotary bearing 520a, and the rotary bearing 520a is rotatably coupled to the lower extension 215c of the bicycle frame 210 (eg, supported in the lower extension 215c) Assembly 528 is supported in one of the sleeves 520). The swivel bearing 520a is rotatable within the sleeve 520. The rotary bearing 520a is attached to the base 250 at an angle A (eg, the angle A is an angle formed between the plane of the base 250 and the rotary bearing 520a). In some embodiments, the swivel bearing 520a is attached to the base 250 via a reinforced frame support member 530.

In certain embodiments, the angle A is between about 30 and 50 degrees. In certain embodiments, the angle A is between about 10 and 30 degrees. In certain embodiments, the angle A is between about 20 and 40 degrees. In certain embodiments, the angle A is between about 40 and 60 degrees. In certain embodiments, the angle A is between about 50 and 70 degrees.

The system 500 allows the bicycle frame 210 to be rotated to the right or left relative to the base 250 (eg, to the right of the base 250 or to the left side of the base 250). The system 500 includes a rewind support mechanism 550 that is used to limit this rotational movement (e.g., to a few degrees). This rollback support mechanism 550 helps to return the bicycle (e.g., frame 210) to its normal upright vertical position. Thus, if the bottom of the bicycle (eg, frame 210) is moved too far to the left, the rollback support mechanism helps to return the bicycle (eg, frame 210) to the right and vice versa. In some embodiments, the rewind support mechanism 550 includes a first one positioned on an opposite side of the bicycle frame 210 (or on an opposite side of one of the bicycle racks 210 that rewinds the support pegs 620) The buffer 610a and a second buffer 610b, or a first spring and a second spring on opposite sides of the bicycle frame 210 (or one of the bicycle racks 210 on the rollback support angle plate). The bumpers 610 or springs provide a return center force.

The bumpers 610 or springs are moveable between at least one extended position and a compressed position. The rotational movement of the rewind support angle plate causes the rewind support angle plate 620 to compress the buffers 610 or springs to the compressed position. Because the bumpers 610 or springs are biased in the extended position, the bumpers 610 or springs then push back against the rewind support angle plates to limit rotational movement about the shaft.

In some embodiments, the system 500 includes a locking mechanism (eg, the locking mechanism is integrated into the pivoting system) and the locking mechanism is adapted to allow a user to prevent pivoting of the bicycle frame. For example, a user may wish to lock the pivoting system while riding or leaving the bicycle, or cycling in a state where the pivoting system is locked to change the sense of fitness. In some embodiments, the locking system can be actuated by a user via a suitable control switch or grip and can prevent the bicycle frame from rotating about the pivot to maintain the frame fixed.

Figure 9 shows that the sleeve 520 is part of the main frame. The sleeve 520 houses the rotary bearings 520a. The nut 520b assists in maintaining the bearings in position and assists in preventing the sleeve 520 from slipping. The illustrated pivot 525 provides that the frame can be rotated around one of the axles. The rewind support mechanism 550 is attached (eg, welded) to and moves with the frame. In some embodiments, the pivot and the sleeve are reversed by the one shown (eg, the sleeve can be part of the base).

As used herein, the term "about" means plus or minus 10% of the reference value. For example, one embodiment in which the diameter of the flywheel 105 is about 10 inches includes a diameter between 9 and 11 inches.
