Description

Technical field

[0001] The invention relates to an exercise bike for strength exercises, on whose two pedals the user's feet rest in order to maintain a balance of the two feet so that the user does not tip over or fall during training. State of the art

[0002] Commercially available conventional fitness equipment is often equipped with a resistance unit to provide rotational resistance during training, allowing exercisers to choose between different rotational resistance levels depending on the training mode.

[0003] TW M633954U discloses a complex force-exerting structure of a rowing machine, which structure includes a base frame, a paddle unit, a first shaft, a paddle coupling unit, a resistance unit, a handle unit, a second shaft, and a handle coupling unit. To use the rowing machine, a first actuating force is applied to the paddle unit to drive a paddle one-way drive wheel and the first shaft to rotate in a first rotational direction. When the first actuating force is reduced or disappears, the paddle one-way drive wheel is driven to rotate idle in a second rotational direction on the first rotational shaft. A second actuating force is applied to the handle unit to drive the handle coupling unit to rotate in the first rotational direction.When the second operating force decreases or disappears, the second restoring force drives the handle one-way wheel, causing it to rotate freely in the second rotation direction on the second rotating shaft. This allows a combined training effect of rowing and handle pulling to be achieved.

[0004] The resistance unit of the conventional rowing machine of the type mentioned above is arranged on the base frame, which makes the overall volume large and heavy, so that the resistance unit cannot be pulled and moved at will and cannot be used for rowing machines of other specifications or fitness equipment of other types.

[0005] TW I855983 B discloses a resistance unit and a fitness device comprising this resistance unit, the resistance unit comprising: a base; an electrical resistance unit attached to the base; a drum attached to an output shaft of the electrical resistance unit and rotating together with the output shaft, the electrical resistance unit imparting rotational resistance to the drum; and a pull rope attached to the drum and wound around the drum for use solely for fitness purposes. The fitness device combined with the resistance unit comprises a resistance unit removably attached to at least one fitness device frame so as to be installable for use on any fitness device.

[0006] Although the resistance unit from the TW I855983 B can be used alone, the two feet are at different heights during one-handed training because only one foot is designed for stepping and the other foot is on the ground. This can easily cause the feet to lose balance and fall, which poses a risk. Furthermore, the overall weight is relatively heavy and the device is difficult to carry and move, making it less than ideal for one-handed use. Object of the invention

[0007] The invention is based on the object of creating an exercise bike for strength exercises which eliminates the deficiencies mentioned in the prior art. Technical solution

[0008] The object is achieved according to the invention by an exercise bike for strength exercises having the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0009] The invention provides an exercise bike for strength training, comprising: a base body including a receiving box and two pedals, the receiving box extending longitudinally, the two pedals being arranged on either side of the receiving box and extending horizontally outward in the transverse direction; an electrical resistance unit mounted in the receiving box and provided with an output shaft for transmitting the driving force; a cable drum mounted on the output shaft and rotatable with the output shaft, the electrical resistance unit providing rotational resistance to the cable drum; a traction cable, one end of which is attached to and wound around the cable drum, and the other end of which is a free end projecting from the receiving box; a control unit housed in the receiving box and signal-connected to the electrical resistance unit;and a control knob located on the outer surface of the receiving box and electrically connected to the control unit. By applying an external force to the free end, the traction rope is pulled to overcome the rotational resistance. When the external force is reduced, the electrical resistance unit retracts the traction rope via the rope drum. By adjusting the control knob, the rotational resistance is changed by the control unit.

[0010] According to the invention, the electrical resistance unit is a motor or an electromagnetic brake.

[0011] According to the invention, the electrical resistance unit is arranged at one end of the receiving box, and the free end of the traction cable is located at the other end of the receiving box.

[0012] According to the invention, the electrical resistance unit and the rotation axis of the cable drum are arranged horizontally in the transverse direction, and the traction cable is wound around a horizontal rotating wheel and a vertical rotating wheel and passes through the receiving box.

[0013] According to the invention, the free end is selectively connected to a handle, wherein the free end is provided with a first connecting element and the handle is provided with a second connecting element, wherein the first and the second connecting element are detachably connected to one another.

[0014] The first connecting element has a gap, wherein a locking pin is movably arranged on one side of the first connecting element, wherein the gap is closed or opened by pressing and releasing the locking pin in order to connect and detach the first and second connecting elements to one another.

[0015] According to the invention, the handle is a one-handed or two-handed handle.

[0016] According to the invention, a carrying handle is arranged at one end of the receiving box and two rollers are arranged at the other end of the receiving box.

[0017] According to the invention, the receiving box is composed of a housing and a base, wherein the two pedals are arranged on both sides of the base, wherein a through hole is arranged on the surface of the upper part of the housing in such a way that it passes through the surface of the upper part of the housing, so that the free end is led out of the receiving box via the through hole.

[0018] According to the invention, an opening is arranged on the surface of the upper part of the housing such that the opening passes through the surface, so that the control button protrudes from the receiving box via the opening and is arranged on the outer surface of the receiving box.

[0019] The inventive home trainer for strength exercises has the following advantages: 1. The home strength training machine has a small volume, light weight and small footprint, making it easy to move and carry, allowing users to use the home strength training machine for solo training in confined spaces. 2. The exercise bike has two pedals located on either side of the base body, extending outwards, and designed to allow the user's two feet to rest on the two pedals, with the base body remaining stable and fixed to a floor due to the user's body weight and not shifting during exercise. 3. By placing both feet on the pedals so that the feet are at the same horizontal level, the two feet remain balanced and the user does not tip over and fall. 4. The handle may be designed as a one-hand grip so that the user can grasp the handle with one hand, whereby the user exerts a force by pulling the handle alternately up and down with one hand via the handle and the pull rope in order to overcome the rotational resistance and thus exercise one hand. 5. Alternatively, a two-handed grip can be used as a handle, so that the user's two hands can hold the handle at its two ends and synchronously pull the handle up and down repeatedly, whereby a pulling force can be exerted via the handle and the pull rope to overcome the rotational resistance and thus simulate training with a dumbbell. 6. The user can grasp the carrying handle at one end of the receiving box with one hand so that the two rollers at the other end of the receiving box rest on the ground and the main body is held in an inclined position, whereby the main body can be pulled, moved and placed at any location in a force-saving and convenient manner by exerting force on the carrying handle.

[0020] Objects, features, and advantages of the present invention will be explained in more detail below with reference to the detailed description of an embodiment and the accompanying drawings. The invention is not intended to be limited to the description and the accompanying drawings.

[0021] As in Fig. 1 to Fig. 3, the invention relates to an exercise bike for strength exercises, comprising a base body 1, an electrical resistance unit 2, a cable drum 3, a pull cable 4, a control unit 5 and a control knob 6.

[0022] The base body 1 comprises a receiving box 11 and two pedals 11, wherein the receiving box 11 extends in the longitudinal direction X, wherein the two pedals 12 are arranged on both sides of the receiving box 11, extend in the transverse direction Y, are wing-shaped and are provided so that the user's feet can stand on the pedals 12. The receiving box 11 is a closed box consisting of a housing 111 and a base 112, wherein a through hole 13 and an opening 14 are arranged on the surface of the upper part of the housing 111. The two pedals 12 are each arranged on both sides of the base 112. A carrying handle 15 is arranged at one end of the base 112 of the receiving box 11, and two rollers 16 are arranged at the other end of the base 112.By pulling the carrying handle 15 upwards so that the two rollers 16 are on the ground and the base body 1 is held in an inclined position, the base body 1 can be pulled and moved by exerting a force on the carrying handle 15.

[0023] The electrical resistance unit 2 is mounted in the receiving box 11. The electrical resistance unit 2 is a motor or an electromagnetic brake arranged at one end of the receiving box 11. The electrical resistance unit 2 is equipped with a power supply end 21 and a power switch 22, wherein the power supply end 21 is to be electrically connected. The power supply end 21 and the power switch 22 are both exposed at one end of the base 112, and a mains power can be connected to the power supply end 21 to supply the electrical resistance unit 2 with power for its operation. The power supply of the electrical resistance unit 2 is turned on and off by means of the power switch 22. The electrical resistance unit 2 is equipped with an output shaft 23 for transmitting the driving force.

[0024] The cable drum 3 is attached to the output shaft 23 of the electrical resistance unit 2. The cable drum 3 is located in the receiving box 11 and rotates with the output shaft 23. The electrical resistance unit 2 provides rotational resistance to the cable drum 3. The electrical resistance unit 2 and the rotation axis of the cable drum 3 are arranged horizontally in the transverse direction Y.

[0025] The traction cable 4 is attached at one end and wound onto the cable drum 3. At the other end of the traction cable 4, a free end 41 is provided, which is wound in turn around a horizontal rotating wheel 42 and a vertical rotating wheel 43 (see Fig. 4) and further through the through hole 13 out of the other end of the receiving box 11. The free end 41 is optionally connected to a handle 44 or 44A, whereby the handle 44 is a one-hand handle and the handle 44A is a two-hand handle (see Fig. 5). At the free end 41, a first connecting element 45 with a gap 451 (see Fig. 6), and a locking pin 452 is movably arranged on a lateral side of the first connecting element 45. The handle 44 is provided with a second connecting element 46. By pressing or releasing the locking pin 452, the gap 451 is closed or opened to connect and detach the first and second connecting elements 45, 46. The rotational resistance is obtained by the separable connection of the handle 44 to the free end 41. If an external force, which is a tensile force, is exerted on the free end 41 via the handle 44, the traction cable 4 is pulled to overcome the rotational resistance. If the external force is reduced, the electrical resistance unit 2 retracts the traction cable 4 via the cable drum 3.

[0026] The control unit 5 is arranged in the receiving box 11 and signal-connected to the electrical resistance unit 2 in order to control the magnitude of the rotational resistance output by the electrical resistance unit 2.

[0027] The control knob 6 protrudes from the opening 14 and is thus arranged on the outer surface of the receiving box 11. The control knob 6 is electrically connected to the control unit 5. By adjusting the control knob 6, the rotational resistance is changed via the control unit 5.

[0028] To use the exercise bike, Fig. 1, Fig. 2 and Fig. 3. For one-handed training, a one-hand grip is previously selected as handle 44. Next, the control knob 6 is rotated to make a setting on the control unit 5. Thus, the magnitude of the rotational resistance to be output by the electrical resistance unit 2 can be automatically controlled. As shown in Fig. As shown in Figure 7, the two feet of a user B stand on the two pedals 12 arranged on both sides of the receiving box 11 and extending horizontally in the transverse direction Y. Due to the user B's own body weight, the base body 1 remains stable, fixed to a floor, and does not shift. At the same time, the two feet of user B can remain at the same horizontal height and thus be kept balanced, preventing the user from tipping over and falling. User B grasps the handle 44 at the free end 41 of the pull rope 4 with one hand and repeatedly pulls the handle 44 up and down with one hand. In this way, the external force (pulling force) is exerted via the handle 44 and the pull rope 4 to overcome the rotational resistance output by the output shaft 23 of the electric resistance unit 2. Thus, the user can perform the exercise with one hand.

[0029] For use of the exercise bike for training with two hands, Fig. 3, Fig. 5 and Fig. 8. For training with two hands, a handle 44A is substituted, which is a two-handed handle. First, the locking pin 452 is pressed down (see Fig. 9) that the locking pin 452 no longer closes the gap 451 so that the gap 451 is opened. Thus, the second connecting element 46 can be released from the first connecting element 45 via the gap 451. Then, the handle 44A is replaced for two-handed gripping by inserting the second connecting element 46 of the handle 44A over the gap 451. After that, the locking pin 452 is released so that the gap 451 is closed with the locking pin 452 to prevent the first and second connecting elements 45, 46 from moving and detaching from each other. Further, the control knob 6 is rotated to make an adjustment in the control unit 5. Thus, the magnitude of the rotational resistance to be output by the electrical resistance unit 2 can be automatically controlled. The two feet of the user B stand on the two pedals 12 arranged on both sides of the receiving box 11.Due to user B's own body weight, the base body 1 remains stable, fixed to the ground, and does not shift. At the same time, user B's two feet can remain at the same horizontal height and thus be kept balanced, preventing the user from tipping over and falling. User B simultaneously grasps both ends of the handle 44A with his hands and repeatedly pulls the handle 44A up and down with both hands. In this way, the external force (pulling force) is exerted via the handle 44A and the pull rope 4 to overcome the rotational resistance output by the output shaft 23 of the electrical resistance unit 2. This allows the user to simulate exercising with both hands using a dumbbell.

[0030] As in Fig.As shown in Figure 10, the handle 44 and the pull rope 4 must be separated to move the base body 1. User B can hold the carrying handle 15 at one end of the base 112 of the receiving box 11 with one hand so that the two rollers 16 at the other end of the base 112 rest on the ground. The base body 1 is then held at an angle, and a force is then exerted on the carrying handle 15. In this way, the base body 1 can be pulled, moved, and placed anywhere conveniently and effortlessly.

[0031] The exercise bike for strength training according to the invention has the following advantages. The exercise bike has a small volume, a low weight, and a small footprint, making it easy to move and carry, allowing user B to use the exercise bike for solo training in confined spaces. User B stands with both feet on the two pedals 12, which are located on either side of the base body 1 and extend outwards. This keeps the feet at the same horizontal height and thus maintains balance, preventing the user from tipping over and falling. Furthermore, a one-hand or two-hand grip can be used as handlebars 44 and 44A, respectively, for training with one or both hands.

[0032] Although the present invention has been described in detail using an exemplary embodiment, it will be understood by those skilled in the art that the invention is not limited to this exemplary embodiment. Rather, modifications are possible such that individual features can be omitted or other combinations of features can be implemented, as long as the scope of the appended claims is not exceeded. The disclosure of the present invention includes all combinations of the individual features presented.
