The present invention is in the field of devices that simulate physical exercise and more particularly it refers to a recreation and physical training simulator that enables users to perform movements and controlled inclinations.
Cycling is one of the physical activities preferred by people who carry out some physical activity as it allows the development of cardiorespiratory and muscular skills. Moreover, it is widely known that cycling improves muscular tone, prevents the appearance of arthrosis, fosters a healthy heart, and delays aging. In addition to strengthening the body, cycling prompts hormone release improving mood and generating a feeling of peacefulness.
Although millions of people use bicycles daily in streets, tracks, or mountains, stationary bicycles for physical training are now gaining more popularity. Stationary bicycles are devices that simulate a bicycle but allow the same physical results to be obtained in enclosed environments. The main advantage of stationary bicycles over conventional ones is that they allow users to exercise from the comfort of their homes or gym without falling off, encountering bad weather, or crowded streets. Likewise, stationary bicycles allow controlling exercise intensity depending on the physical aptitudes of the user. So, it is possible to set up resistance levels that would not be possible to get on a standard bicycle on regular terrain.
On the other hand, pedaling the stationary bicycle provides the means to work on the muscles in the lower part of the body. Quadriceps and sural triceps are constantly exercising, and whenever the user presses the pedals, the gluteal muscles exercise separately. With an increase in pedaling resistance, those muscles must exert greater force, developing more muscle mass.
Despite the many advantages of stationary bicycles, the abdominal, back, and upper limb muscles are worked to a lesser extent on a stationary bicycle. Hence, the designs of conventional stationary bicycles fail to engage those muscle groups exercised while pedaling a conventional bicycle, including the muscles required for propulsion and balance of the bicycle and those used when the user changes direction.
In the same way, conventional stationary bicycles offer a limited experience to the user because they simulate a reduced amount of the total dynamic forces that a user faces when riding a traditional bicycle. Hence, continuous pedaling in a static position can be tedious and monotonous, leading to the search for new configurations that allow a more authentic experience for the user.
Simulators allowing tilting of the bicycle to rotate on an axis located directly underneath the user are disclosed in publications such as U.S. Pat. Nos. 4,887,967 and 4,711,447. The invention of U.S. Pat. No. 5,364,271 shows a cycling simulator that electronically connects the mechanical support assembly to a computer to simulate physical activity more realistically on different types of terrain and tracks. The simulator allows users to have the chance to do “wheelies” through a distinctive feature in which the bicycle rotates in a backward direction on an axle close to the rear wheel.
U.S. Pat. No. 8,371,992 B2 shows a device that simulates riding a bicycle. The simulator comprises two mounting points that hold the frame, which is configured to pivot about the first and the second mounting point in response to user movement. Consequently, the two mounting points allow the rider to move the entire frame and its components from left to right and tilt the bike within the stationary frame in response to forces applied to the handlebars and pedals.
Although the state of this technique has achieved relevant breakthroughs, there is still a need for cycling or motorcycling simulation systems that allow more muscles to work simultaneously (legs, central core, arms, upper muscles, etc.). Therefore, this requires systems that allow users to perform more movements of different kinds during the same experience.
Similarly, there is a market for simulation systems that involve a new way of physical exercise and recreation to avoid desertion and monotony. As a result, it is necessary to develop systems that allow users to perform movements and inclinations with greater freedom. It is also indispensable that simulators allow a single experience to perform lateral and backward movements and tilts without incorporating motors or driven cylinders.
Accordingly, the present invention discloses a cycling or motorcycling simulator for recreation and physical exercise characterized by allowing left and right movements and inclinations that can be controlled with the handlebars or body thrust.
The simulator of the present invention also allows tilting backward to simulate wheelies without using motors or driven cylinders since all its movement is due to the effort and balance of the user. Thus, simulating an actual bicycle or motorcycle.
Additionally, the present invention has a greater range and possible movements and, therefore, it reduces the monotony of exercise and allows the user to perform aerobic or cardiovascular training.
The simulator of the invention makes possible to perform anaerobic exercises to work more muscles than on a conventional exercise bike. Such as legs, thighs, abdomen, back, arms, and forearms.
Another advantage of the invention is its convenience, as it does not take up more space than a conventional stationary bicycle. So, it can be used at home or in the gym, and users can adjust it to match their height.
From a structural perspective, the device of the present invention allowing the simulation of cycling or motorcycling movements is divided into six parts. These are connected to each other to get the device to function optimally.
In first place, the simulator consists of a base (1) supported on the floor holding all the parts of the invention. This base can be formed by two metal profiles parallel to each other joined at each end to two other metal profiles located perpendicularly. In another embodiment, the base can be circular or oval.
The second part corresponds to a mounting base (2) mounted on the base (1). On the mounting base (2), the weight of the simulator is concentrated when it is on the base (1) or does not have the lifting system (3), but when it is raised, the weight is concentrated on the lifting system (3). The mounting base (2) consists of profiles that fit on a rectangular sheet to give it the shape of an inclined box. The mounting base (2) may have holes in its lower part to screw lower shock absorbers (3d). These same holes are used to screw the mounting base (2) to the base (1) if the user wants to disable the lifting system (3).
The mounting base (2) was specially designed to attach the lifting system (3), the lower coupling system, and the lateral tilt system (6) so that the simulator can be simultaneously rotated to the left or the right while being lifted. On its rear side, the mounting base (2) has a lower rectangular cavity (2a) with a frame protruding from the housing for the coupling of the lifting system (3), and above this cavity has a circular hole for the adjustment of the main shaft (5). While on its front side, it has a lower hole of circular shape for the adjustment of the central axis (5). In one possible embodiment, the front side has a top opening to adjust the lateral tilt system.
The third part of the simulator corresponds to the lifting system (3), consisting of a lifting profile (3a) connected to a rotating shaft (3b) and bushings or bearings (3c) with supports or bearings (3g) connected to the base (1) by screws and positioned at the ends of the rotating shaft (3b), to allow rotation and lifting for the lifting system (3). In addition, such a system may consist of lower shock absorbers (3d) or any element attached to the mounting base (2) to cushion or soften the fall after lifting the bicycle, simulating that it was on the rear tire, which is called doing a wheelie or a rocking horse like movement. Finally, the lifting system (3) may consist of adjustment support (3e) positioned around the lifting profile (3a) and preferably attached to the base (1) using screws. This support allows for adjusting the angle and the maximum lifting height of the stationary bicycle.
The lifting system (3) works when the user pushes its body backward or jumps by pulling the handlebars toward its body, thus changing the machine's center of gravity to lift the bicycle and achieve wheelies without using motors or driven cylinders. In addition, the lifting system (3) can be adjusted so that when the lifting profile (3a) enters further into the mounting base (2) and thus facilitating the lifting of the simulator. Similarly, when the lifting profile (3a) enters less into the mounting base (2), more effort is required to lift the simulator.
The fourth part of the invention corresponds to the frame (4), which is made up of profiles giving a bicycle-shaped structure to the simulator allowing the union of other parts of the frame that correspond to handlebars (11), a resistance element (8), the pedals (7), the seat (10), lateral shock absorbers (9) and the braking mechanism (29).
In a preferred aspect, the frame comprises two connecting profiles (4a) (4b) The profile A (4a) attaches the handlebar (11) to the lateral tilt system (6) and is coupled inside the mounting base (2) and anchored to the main shaft (5). Likewise, the frame (4) is constituted by profile B (4b), which is coupled to the main shaft (5) outside the mounting base (2), to the profile (4c).
In another preferred embodiment, the bicycle frame (4) also includes a resistance element (8) located at the rear, which produces resistance when pedaling. By way of example, and without limiting the invention, the resistance element (8) can consist of a flywheel weighing 13 to 30 kg.
In an embodiment of the invention, the rear resistance element (8) can include, by way of example: an inertia flywheel, a disk, a wheel, a roller, geared wheels, a simulator already existing in the market that can be adapted, or some system or mechanism that generates resistance to the user when pedaling without affecting the mobility features of the bicycle.
In a preferred embodiment, the bicycle frame (4) consists of pedals (7) that interact, for example, by chain or belt transmission with the rear resistance element (8) to generate movement.
In one possible embodiment of the invention, the frame (4) consists of footrest supports instead of pedals that serve when users want to simulate devices other than a bicycle such as a motorcycle, jet ski, or an animal for video games.
In another preferred embodiment, the lateral shock absorbers (9) stabilize the simulator by preventing the bicycle from tipping sideways and help the user to keep the simulator centered more easily. These lateral shock absorbers (9) are located on the lower sides of profile A (4a) inside the mounting base (2). Screws hold them on the sides of profile A (4a). The side shock absorbers (9) can be springs or elastomers. These are necessary if the lateral tilt system (6) is not used or is disconnected from the handlebars (11). In this case, the user will tilt the bicycle by pushing its body sideways. The side shock absorbers (9) will help to return it to a centered position.
In a preferred embodiment, the seat (10) is adjustable in both distance and depth. Moreover, it is interchangeable, and the user can put on the seat that suits their preferences in size, shape, material, and color.
In another preferred aspect, the handlebar (11) is adjustable in both height and depth and is clamped to an orientation tube (14) that is held from the frame (4) by fixed clamps or rings (20a) and pivots on bushings or bearings (20). With the handlebar connected to the lateral tilt system (6), the user can control the tilting or turning movements of the simulator to move it in all the different possible rotation angles. It is also possible to disable the lateral tilt system and leave the handlebar fixed or fix it with the knob (30) to the frame (4) to prevent it from rotating.
In a preferred embodiment, the handle may have any steering wheel shape, such as the steering wheel for a ship or car, among others.
In a preferred embodiment, the braking mechanism (29) makes it possible to brake the rear resistance element (8) and thus regulate the effort made by the user when pedaling. For this purpose, there is a braking or resistance regulation knob (28), which, when turned, tightens, or loosens a cable so that the clamps exert pressure on the rear resistance element (8). Thus, requiring more or less pedaling force. This braking mechanism can be mechanical with a plug, magnetic skid, or electromagnetic induction. In addition, it can be driven manually or automatically with a motor or other device.
The fifth part of the stationary bicycle is the lower coupling system that allows the connection of profile A (4a) with profile B (4b). This system consists of the main shaft (5) that crosses the lower ends of both profiles. This shaft can rotate on a support structure (12), bushings or bearings (17), or any element that allows its rotation.
The main shaft (5) of the lower coupling system forms a fixed angle (B) for the base (1) of 25 to 45 degrees when the mounting base (2) is positioned on the base (1) without forming any angle of elevation. When the lifting system (3) is raised, the angle (B) varies depending on the force applied by the user to perform wheelies. Along with that, when the user turns the handlebars (11) to the left or right, the main axle (5) rotates on the supports (12), bushings, or bearings (17), allowing for tilting or turning the whole bicycle to the left or right.
Finally, the sixth part of the invention corresponds to the lateral tilt system that allows the user to turn the bicycle to the left or right with different degrees of freedom. This system comprises of an upper flap (13) that includes an opening, two spherical plain bearings and rod ends or coupling levers, one upper (6a) and (6b), and two coupled at the bottom (6f) (6g) or (18b)(18c), a rotating tube (6d) and a lower shaft (15) or coupling (18d).
In a preferred embodiment, the upper flap (13) corresponds to a ring-shaped part welded or clamped to the lower part of the guide tube (14) of the handlebar (11). The flap (13) includes a hole with an upper spherical plain bearing (6a) through a shaft or screw for engaging.
In a preferred embodiment, the upper spherical plain bearings (6a) and (6b) are joined by a coupling or screw at the center. The ball joint (6a) engages the upper flap (13), and the ball joint (6b) engages an upper lever (6c) that is part of the rotating tube (6d).
In a preferred aspect of the invention, the rotating tube (6d) is located parallel to profile A (4a) and rotates on its axis, as a result, of the upper (16a) and lower (16b) connecting pieces that are anchored to the profile (4a) keeping the tube (6d) fixed but allowing its rotation. The tube (6d) has levers set perpendicularly. At its upper end, a lever (6c) is welded to it, and at its other end, the lower lever (6e) or (18a) is fixed to it.
In another preferred embodiment of the invention, the lower ball joint (6f) or (18b) fits into the lower lever (6e) or (18a), which is part of the rotating tube (6d) and the lower ball joint (6g) or (18c) is coupled to the lower shaft (15) or coupling (18d) which is fixed or anchored to the mounting base (2).
The device of the invention has other uses different from the stationary bicycle. For example, different electronic systems are attached to the stationary bicycle in one embodiment, allowing the measurement of different variables while exercising or as a video game simulator. Some adaptations are the handlebar button box, brakes with sensors, throttle handle, steering control, jump sensor, inclination sensor, pedal sensors, maximum inclination sensor, and braking motor.
In a possible embodiment, the stationary bicycle has control boxes with buttons on the handlebars. These control boxes allow users to activate different abilities or options that other video games have.
In another embodiment, the stationary bicycle has two brakes adapted (22) on the handlebars (11), which have sensors that simulate the braking in a bicycle video game or the clutch in a motorcycle game. These brakes can have housings similar to conventional bicycle brakes to give a realistic feel to the game. Similarly, the handlebar (11) can have an adapted throttle handle (33) to simulate motorcycle games, where the movement of the handle activates a sensor that allows accelerating in the video game.
In one of its embodiments, the invention has coupled a direction control commanding left, and right turns for the video game character. For these turns, a potentiometer can be used with geared wheels attached to the handlebars. In this way, when the handlebars are turned, the gear wheel of the handlebars will turn the gear wheel of the potentiometer, sending the signal to the video game for the character to make the turn. For direction control, it is also possible to use any sensor that allows sending the signals to control the turns in the video game.
In one embodiment, the stationary bicycle has a jump sensor that interacts with the lifting system (3) or the mounting base (2). This sensor will signal the program or video game to indicate that the user has lifted the bicycle from the base (1), interpreted as a jump in the video game.
The stationary bicycle may have in one embodiment a lift sensor located on the sides of the lifting bracket (3e) or activated using the rotating shaft (3b). The sensor could send a signal that the video game processing will interpret to activate the different skills of the video game character.
In another possible embodiment, the invention has sensors on the pedals which can send two signals, one when pedaling forward and thus accelerating the bicycle, and another, when pedaling backward, which would reverse the bicycle. This mechanism can be developed using an optocoupler or any electronic system that allows sending impulses or signals to a processing block, differentiating one signal when the pedals are rotating, simulating a forward pedaling from another signal when performing backward pedaling.
The device of the invention in one embodiment has coupled lateral tilt sensors, which allow knowing the angle of lateral movement of the bicycle. In addition, it can have two maximum tilt sensors, one on the left and one on the right, which will detect when the bicycle has been tilted to the maximum sideways. Such sensors are useful for different video games.
A motor acting accordingly to the programming commands and requirements of the video game can be installed on the braking system of the invention. Furthermore, this motor will adjust the jaws, apply pressure, or bring a magnetic field over the resistance element (8) to prevent easy pedaling when the video game presents scenes of climbing hills or when the user has to make a greater pedaling effort.
In a possible embodiment, the stationary bicycle can include two accessories to move it easily. The first accessory is a handle at the front of the base (1) to lift the bicycle so that it rests on the bicycle's transport wheels installed underneath or at the rear of the base.
The stationary bicycle includes a base for positioning a PC keyboard and/or mouse or a video game controller in another possible embodiment.
The invention in one embodiment can have an existing electric power generator or dynamo on the market, coupled to the rear resistance element (8), to transform the kinetic energy produced by pedaling into electrical energy. This energy can have different uses, such as to charge a battery, a mobile device, or use it for some electrical operation of the bicycle itself.
The simulator can include in one embodiment a system to simulate the descents and climbs of a mountain that would consist of a fixed platform. It would be installed under the support or bearings (3g) to further raise the simulator with respect to the base (1) that goes on the ground. Furthermore, a second mobile platform under the mounting base (2) whose function is to raise or lower the simulator from the front and the mobile platform could be driven by an electric motor, a worm gear, hydraulic cylinders, or any available system allowing such a function. This mobile platform can be programmed with a video game or sports training application to rise when users simulate a mountain ascending or descending. It can also make a quick upward or downward movement to simulate uneven terrain, making the experience more realistic for the user.
In one aspect, the simulator can include devices for wind and water simulation. The wind would be simulated by the installation of a fan, so the user receives wind in its face according to the cyclist's pedaling speed or the speed it is riding at, in the video game. Likewise, a small water pump or some other system can be added to throw a little water towards the user when there are rainy areas in the video game or when passing over water.
The invention can be fitted with a mechanism to simulate uneven or rocky terrain using a motor or vibrator connected to a computer via a control card and to the mounting base (2), the base (1), or the lifting system.
In another possible embodiment, an activation system can be added to the simulator to introduce some form of payment when used in a commercial setting.
In another embodiment, the simulator's frame structure can be modified so that the design is in the shape of a character, animal, or sports device such as dolphins, birds, horses, motorcycles, ATVs, jet skis, among others. Any device on which the user can get on and control the handlebars by hand or pulling a strap. Also, the handlebar can be shortened, and a strap can be attached to control animal-shaped devices. The user pulling the right strap will turn the handlebar to the right, and if the user wants it to return will have to pull the left strap. To lift the simulator, the user will pull both straps simultaneously and by pulling its body backward.
For the present invention to be understood and put into practice, the attached figures, and a detailed description of embodiments of the invention are referenced as follows:
In general terms, the invention depicted in
Specifically,
In
As for the structural elements of the frame (4), the pedals (7) interact with the rear resistance element (8), the lateral shock absorbers (9) are intended to stabilize the bicycle, the seat (10) can be adjusted to the user's build. The brake mechanism (29) can be mechanical, magnetic, or by electromagnetic induction. The handlebar (11) can control the tilting or turning movements of the bicycle if the orientation tube (14) is connected to the lateral tilt system (6) through the upper flap (13).
From
From
It is worth noting that the lifting system (3) of the invention can be removable depending on each user's particular needs and requirements. In this way, the lifting system (3) can be fixed or disabled by coupling/decoupling the lower holes (2b) with the holes (la) of the base using screws.

However, they are unnecessary when the simulator is controlled by the handlebar (11) and the tilt system (6). On the contrary, if the tilt system (6) is disabled, the lateral shock absorbers (9) are necessary as the user will tilt the bicycle by pushing its body sideways. The shock absorbers will help the user to return to a centered position.
The main shaft (5) that constitutes the lower coupling system rotates on any element that allows the main shaft (5) to rotate. That element can include either supports (12) anchored by screws to the base (2) or bushings or bearings (17) located within a support structure (19) anchored to the base (2). The main shaft pivot (5) allows the bicycle to tilt or turn to the left or right when the user turns the handlebars (11) or applies some force by pushing its body.
Functionally, when a turn occurs in the handlebar, a response is generated by the lateral tilt system that allows the movement of the simulator. In that way, when the user turns the handlebar (11), the orientation tube (14) is rotated, and the upper flap (13) is displaced to transfer this movement to the part formed by the ball joints (6a) and (6b). In doing so, the ball joint (6b) pushes the upper lever (6c), which is part of the tube (6d), causing the rotating tube (6d) to rotate on its axis in the opposite direction the handle (11) is turned. Thus, the rotating tube (6d) will rotate to the right if the handle is turned to the left. When the tube (6d) rotates, it also moves laterally the lower lever shaft (6e), which is fixed to it. Then, the lower lever shaft (6e) pulls or pushes the piece formed by the union of the two ball joints (6f) and (6g). In this way, the ball joint (6g) fixed to the shaft (15), which is anchored to the mounting base (2), has no possibility of movement producing a reaction force that forces the profile (4a) connected to the upper (16a) and lower (16b) connecting pieces to move on the main axis (5). Hence, causing the simulator frame (4) to tilt and turn to the right or left. Consequently, turning the handle (11) to the left will cause the simulator to tilt and turn to the left. Likewise, turning the handle (11) to the right will cause the simulator to tilt and turn to the right.
It is worth noting that the simulator's turning angles and lateral tilt will depend on the length between the ball joints and the distances from the ball joints to the axes of rotation of each tube, both at the top and at the bottom. Thus, varying any of these distances also changes the lateral tilt angle.
In another relevant aspect of the invention, the handlebar (11) of the simulator can comprise different configurations according to the user's personal preference. The first handlebar shown in
The simulator of the present invention can be used to play video games. So, while the frame (4) and the simulator systems can be fitted with sensors, it is possible to locate controls on the handlebars (11) that provide information to a computer via a control card. In this way, the user experiences more realistic sensations when playing video games.
