Description

Technical Field

[0001] The utility model relates to the technical field of bicycles, in particular to a fitness bicycle convenient to move. Background Art

[0002] As a commonly used fitness or rehabilitation device, bicycles have a wide range of applications in daily life. Traditional bicycles mainly consist of a vehicle body and two pedals provided on the vehicle body. When in use, the user steps on the two pedals with both feet to exercise, similar to the action of pedaling a bicycle, so as to achieve the purpose of exercising the lower limb strength.

[0003] At present, there are mainly two forms of fitness bicycles. One is the seatless type, and the other is the seated type. Compared with the latter, the seatless bicycle is smaller in size and is convenient to carry and transport; thus, it has a relatively wide range of applications. For example, reference can be made to the bicycle disclosed in the publication number CN213159170U.

[0004] However, the existing bicycles still have deficiencies in actual use. The main problem is that in order to prevent the vehicle body from sliding during use, generally, the bottom of such a bicycle does not have rollers, but is directly supported by feet. In this way, although it ensures that it will not slide, it also causes that when it needs to be transferred, the entire bicycle needs to be lifted for transfer, so it takes a lot of effort to transfer it. Therefore, it still needs to be improved. Summary of the Utility Model

[0005] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide a fitness bicycle convenient to move.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fitness bicycle convenient to move, comprising a vehicle body and a plurality of feet provided at the bottom of the vehicle body for supporting the vehicle body. The feet can move between a first position and a second position relative to the vehicle body; a roller is provided on the feet and can switch between a first state and a second state as the feet move. In the first position, the feet are unfolded at the bottom of the vehicle body to support the vehicle body, and the roller shrinks into the feet under the extrusion of the ground to enter the first state; when the feet are in the second position, at least part of the wheel surface of the roller protrudes from the bottom surface of the feet to support the vehicle body to enter the second state.

[0008] Compared with the prior art, the advantages of adopting this solution are as follows:

[0009] In this solution, rollers are provided and configured to be linked with the legs. When the bicycle is used for exercise, the legs can be unfolded into the first position. At this time, the rollers are in the first state and retracted in the legs. In this way, the entire bicycle body is supported by the legs, thereby ensuring that the bicycle body is not easy to slide when in use.

[0010] When the bicycle needs to be moved, the support leg can be moved to the second position. At this time, the roller is in the second state, that is, the wheel surface of the roller at least partially protrudes from the bottom surface of the support leg. At this time, the roller can touch the ground to support the entire bicycle body. In this way, with the help of the roller, the user can directly push the bicycle body to move without lifting the entire bicycle body for transfer, which is obviously more labor-saving.

[0011] In summary, the present invention can ensure that the bicycle is not prone to sliding when in use, and can also be easily moved when it needs to be transferred.

[0012] Optionally, the support leg is rotatably connected to the bottom of the vehicle body, and the support leg is movable between a first position and a second position by rotating.

[0013] Optionally, in the second position, the supporting legs are close together on the bottom surface of the vehicle body.

[0014] Optionally, a receiving groove for accommodating the supporting foot is provided at the bottom of the vehicle body corresponding to the supporting foot position; one end of the supporting foot is rotatably connected to the receiving groove; in the second position, the supporting foot is accommodated in the receiving groove.

[0015] Optionally, the roller can move vertically relative to the support foot to achieve switching between the first state and the second state.

[0016] Optionally, the support foot is provided with a guide shaft that can move vertically in the same direction as the roller, and one end of the guide shaft away from the roller extends out of the bottom surface of the support foot as a locking end; the bottom surface of the vehicle body is provided with a locking hole for inserting the locking end of the guide shaft, and the vertical depth of the locking hole is constructed so that when the locking end is inserted into the locking hole and abuts against the end wall of the locking hole, the roller is in the second state.

[0017] Optionally, an elastic member is provided between the roller and the support foot, and the elastic member is used to provide elastic force to drive the roller to maintain a tendency to move vertically upward.

[0018] Optionally, a wheel frame is provided between the guide shaft and the roller, wherein the roller is rotatably connected to the lower end of the wheel frame, and the guide shaft is vertically fixed to the upper end of the wheel frame; a sliding groove for vertical movement of the wheel frame is provided at the bottom of the support foot; the guide shaft vertically moves through the support foot at the wheel groove position so that the locking end extends out of the upper part of the support foot; the elastic member is provided in the sliding groove, and its two ends are respectively connected to the end wall of the sliding groove and the upper end of the wheel frame.

[0019] Optionally, an elastic pin capable of vertically elastic telescoping is provided on the top wall of the receiving groove. When the supporting leg is in the first position, at least a part of the elastic pin protrudes from the top wall of the receiving groove to form a block on the side of the supporting leg, restricting the supporting leg from rotating in the direction of the second position.

[0020] Optionally, the elastic pin includes a spring and a pin body. A vertically extending pin groove is formed on the top wall of the receiving groove.

[0027] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0028] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc. indicating orientations or position relationships are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] Please refer to Figures 1-5 As shown, this embodiment provides a conveniently movable fitness exercise bike, including a vehicle body 1 and a plurality of supporting legs 2 provided at the bottom of the vehicle body 1 for supporting the vehicle body 1. Preferably, 4 supporting legs 2 are provided, symmetrically arranged in pairs at the bottom of the vehicle body 1.

[0030] The support leg 2 can move between a first position and a second position relative to the vehicle body 1. For example, in this embodiment, the support leg 2 is rotatably connected to the bottom of the vehicle body 1, and the support leg 2 moves between the first position and the second position by rotating.

[0031] In the first position, Figure 1 and Figure 2 As shown, the support leg 2 is unfolded at the bottom of the vehicle body 1 to support the vehicle body 1 ; at this time, the support leg 2 extends along the width direction of the vehicle body 1 .

[0032] In the second position, Figure 3 and Figure 4 As shown, the legs 2 are placed together on the bottom surface of the vehicle body 1 , and the legs 2 extend along the length direction of the vehicle body 1 , which is equivalent to folding the legs 2 at the bottom of the vehicle body 1 , thereby reducing the volume of the vehicle body 1 .

[0033] The support leg 2 is provided with a roller 3 which can switch between a first state and a second state as the support leg 2 moves.

[0034] like Figure 2 As shown, when the support leg 2 is in the first position, the roller 3 is compressed in the support leg 2 under the pressure of the ground to enter the first state;

[0035] like Figure 3 As shown, when the support leg 2 is in the second position, the wheel surface of the roller 3 at least partially protrudes and supports the vehicle body 1 with the bottom surface of the support leg 2 to enter the second state.

[0036] In this way, when the bicycle needs to be used, the support leg 2 can be flipped to the first position and unfolded. At this time, the roller 3 is retracted in the support leg 2 to present the first state. In this way, the body 1 is basically supported by the support leg 2, and the roller 3 does not bear the weight of the body 1, ensuring that the body 1 is not easy to slide when in use.

[0037] When the bicycle needs to be moved, the support leg 2 can be flipped to the second position. At this time, the roller 3 protrudes from the bottom surface of the support leg 2 to present the second state. In this way, the support leg 2 is lifted by the roller 3 and is a certain distance from the ground. In this way, the body 1 is basically supported by the roller 3. Therefore, the body 1 can be moved by the rolling of the roller 3 just by pushing the body 1.

[0038] In this embodiment, a receiving groove 11 for receiving the supporting foot 2 is provided at the bottom of the vehicle body 1 at a position corresponding to the supporting foot 2 , and the receiving groove 11 extends along the length direction of the vehicle body 1 .

[0039] One end of the support leg 2 is rotatably connected to the receiving groove 11 , and the other end can be freely flipped, and the rotation axis of the support leg 2 is arranged vertically; in the second position, the support leg 2 is accommodated in the receiving groove 11 .

[0040] It should be noted that the bottom surface of the support leg 2 is not lower than the bottom surface of the vehicle body 1, and preferably they are flush; in this way, it is ensured that the support leg 2 can touch the ground to support the vehicle body 1.

[0041] In some embodiments, the roller 3 can move vertically relative to the support leg 2 to realize the switching between the first state and the second state; specifically:

[0042] As Figure 4 shown, a guide shaft 32 that can move vertically in the same direction as the roller 3 is provided on the support leg 2. For example, a wheel frame 31 is provided between the guide shaft 32 and the roller 3. The roller 3 is rotatably connected to the lower end of the wheel frame 31, and the guide shaft 32 is vertically fixed to the upper end of the wheel frame 31 (as Figure 5 shown).

[0043] A sliding groove 21 for the vertical movement of the wheel frame 31 is formed at the bottom of the support leg 2, and the wheel frame 31 is slidably arranged vertically in the sliding groove 21; wherein, the cross-section of the wheel frame 31 is in a polygonal structure, such as a rectangle, and the shape of the sliding groove 21 is adapted to the wheel frame 31, so as to prevent the wheel frame 31 from rotating circumferentially in the sliding groove 21.

[0044] One end of the guide shaft 32 away from the roller 3 extends out of the top surface of the support leg 2 as a locking end 321. Specifically, the guide shaft 32 vertically penetrates the support leg 2 at the wheel groove position, so that the locking end 321 extends out of the upper part of the support leg 2;

[0045] Correspondingly, as Figure 2 and Figure 4 shown, a locking hole 12 for vertically inserting the locking end 321 of the guide shaft 32 is provided on the top wall of the receiving groove 11. The vertical depth of the locking hole 12 is configured such that when the locking end 321 is inserted into the locking hole 12 and abuts against the end wall (top end) of the locking hole 12, the roller 3 is in the second state, that is, the roller 3 at least partially protrudes from the bottom surface of the support leg 2.

[0046] With such a setting, as Figure 4 shown, when the support leg 2 is flipped to the second position, the locking end 321 is exactly aligned with the locking hole 12, and then the locking end 321 is vertically inserted into the locking hole 12. Finally, the locking end 321 abuts against the end wall of the locking hole 12 and cannot be inserted further, so that the guide shaft 32 is blocked and cannot move up further. In this way, after the roller 3 touches the ground, the vehicle body 1 is supported by the wheel frame 31 and the guide shaft 32 to transfer the vehicle body 1.

[0047] In addition, after the guide shaft 32 is inserted into the locking hole 12, the support leg 2 can be positioned to prevent the support leg 2 from flipping, and it is ensured that the support leg 2 does not flip on the ground during the transfer of the vehicle body 1.

[0048] In addition, an elastic member is provided between the roller 3 and the support leg 2. The elastic member is used to provide an elastic force to drive the roller 3 to maintain a tendency to move vertically upward. Specifically, the elastic member is preferably a tension spring 33. The tension spring 33 is located in the chute 21 and sleeved on the guide shaft 32. The two ends of the tension spring 33 are respectively fixed on the top of the wheel frame 31 and the end wall of the lock hole 12. The wheel frame 31 is pulled upward by the tension spring 33 so that the roller 3 has a tendency to move upward.

[0049] When the support arm is in the first position and touches the ground, under the extrusion of the ground, the roller 3 will move upward, thereby driving the guide shaft 32 and the wheel frame 31 to move upward against the elastic force of the tension spring 33. Finally, the roller 3 is received in the chute 21 so that the bottom surface of the support arm can touch the ground to support the vehicle body 1.

[0050] When the support arm is flipped to the second position, the guide shaft 32 is inserted upward into the lock hole 12 under the elastic force of the tension spring 33, and finally the roller 3 enters the second state.

[0051] In order to enable the support arm to maintain an extended state to support the vehicle body 1 when in the first position, in this embodiment, an elastically telescopic elastic pin is provided on the top wall of the receiving groove. Specifically, the elastic pin includes a spring 41 and a pin body 4. A vertically extending pin groove 13 is formed on the top wall of the receiving groove. The pin body 4 is vertically movably inserted into the pin groove 13. The spring 41 is arranged in the first pin groove 13, and its two ends are respectively fixed to the pin body 4 and the end wall of the pin groove 13.

[0052] When the pin body 4 is not subject to external force, under the elastic force of the spring 41, its upper end will extend upward out of the pin groove 13 and enter the receiving groove, and block beside the support leg 2. In this way, under the restriction of the pin body 4, the support leg 2 cannot directly rotate towards the second position to maintain the extended state.

[0053] When it is necessary to flip the support leg 2 to the first position, the pin body 4 can be pressed by hand so that after the support leg 2 passes over the pin body 4, finally under the pressing of the support leg 2, the pin body 4 contracts into the pin groove 13.

[0054] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
