Technical Field

[0001] The present invention generally relates to the field of fitness equipment, specifically to outdoor fitness equipment, and particularly to a hand-cranked vertical bike. Background Art

[0002] The vertical bike and the hand-cranked bike are two different types of outdoor fitness equipment. To expand the functions of outdoor fitness equipment and to enrich the functions of outdoor fitness equipment in a limited space, the hand-cranked bike and the vertical bike can be combined into a hand-cranked vertical bike. In the hand-cranked vertical bike, the hand-cranked bike and the vertical bike share a handle, that is, the same handle is used when using the hand-cranked bike function and the vertical bike function. This poses a problem. When using the hand-cranked bike function, it is required that the two handles are arranged in a staggered manner, one in front of the other or one above the other, and the two handles are rotated by both hands. When using the vertical bike function, it is required that the two handles are coaxial or in the same plane for easy grasping by the user. Using the hand-cranked bike function and the vertical bike function has different requirements for the positions of the two handles, and ordinary handles cannot meet these requirements. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a hand-cranked vertical bike that can switch the position of the handle.

[0013] Pull the second handle to drive the second sliding rod to slide inside the second armrest support tube, so as to switch the second locking mechanism to the unlocked state, and the second armrest support tube can rotate relative to the second connecting seat.

[0014] Release the second handle, and the second sliding rod resets to switch the second locking mechanism to the locked state, so that the second armrest support tube cannot rotate relative to the second connecting seat.

[0015] When the hand-cranked vertical bike is in the first use state, the first armrest support tube, the first handle, the first rotating shaft, the second armrest support tube and the second handle are coaxial.

[0017] According to the technical solution provided by the embodiment of the present application, pulling the first handle drives the first sliding rod to slide, so that the first locking mechanism is switched to the unlocked state, and the first armrest support tube can rotate relative to the first connecting seat to change the positions of the first armrest support tube and the first handle. Similarly, pulling the second handle drives the second sliding rod to slide, so that the second locking mechanism is switched to the unlocked state, and the second armrest support tube can rotate relative to the second connecting seat to change the positions of the second armrest support tube and the second handle.

It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] Please refer to Figures 1 - 12, the hand-cranked vertical bike of the present invention, which comprises: a frame 100; a seat cushion 110 fixedly connected to the frame 100; a footrest 120 rotatably connected to the frame 100 and located below the seat cushion 110; a first rotating shaft 130 rotatably connected to the frame 100, and the first rotating shaft 130 is connected with a first damper; a first hand-cranking mechanism 200, which includes a first connecting seat 210, a first armrest support tube 220 and a first handle 250. The first connecting seat 210 is detachably and fixedly connected to one end of the first rotating shaft 130. The first armrest support tube 220 is rotatably connected to the first connecting seat 210. A first sliding rod 240 is slidably connected in the first armrest support tube 220. The first handle 250 is rotatably connected to the first sliding rod 240. A first locking mechanism 300 is arranged between the first armrest support tube 220 and the first connecting seat 210. Pulling the first handle 250 drives the first sliding rod 240 to slide in the first armrest support tube 220, so that the first locking mechanism 300 is switched to the unlocked state, and the first armrest support tube 220 can rotate relative to the first connecting seat 210. Releasing the first handle 250, the first sliding rod 240 resets, so that the first locking mechanism 300 is switched to the locked state, and the first armrest support tube 220 cannot rotate relative to the first connecting seat 210; and a second hand-cranking mechanism 400, which includes a second connecting seat 410, a second armrest support tube 420 and a second handle 450. The second connecting seat 410 is detachably and fixedly connected to the other end of the first rotating shaft 130. The second armrest support tube 420 is rotatably connected to the second connecting seat 410. A second sliding rod 440 is slidably connected in the second armrest support tube 420. The second handle 450 is rotatably connected to the second sliding rod 440. A second locking mechanism 500 is arranged between the second armrest support tube 420 and the second connecting seat 410. Pulling the second handle 450 drives the second sliding rod 440 to slide in the second armrest support tube 420, so that the second locking mechanism 500 is switched to the unlocked state, and the second armrest support tube 420 can rotate relative to the second connecting seat 410. Releasing the second handle 450, the second sliding rod 440 resets, so that the second locking mechanism 500 is switched to the locked state, and the second armrest support tube 420 cannot rotate relative to the second connecting seat 410. When the hand-cranked vertical bike is in the first usage state, the first armrest support tube 220, the first handle 250, the first rotating shaft 130, the second armrest support tube 420 and the second handle 450 are coaxial. When the hand-cranked vertical bike is in the second usage state, the first armrest support tube 220 is perpendicular to the first rotating shaft 130, the first handle 250 is perpendicular to the first armrest support tube 220, the second armrest support tube 420 is perpendicular to the first rotating shaft 130, the second handle 450 is perpendicular to the second armrest support tube 420, and the first handle 250 and the second handle 450 are parallel.

[0034] In an embodiment of the present invention, with reference to Figures 1 - 3, the frame includes an armrest tube 111, a seat tube 114, and a pedal tube 115. The first rotating shaft is rotatably connected to the armrest tube, the seat is fixedly connected to the seat tube, and the pedal is rotatably connected to the pedal tube. The armrest tube 111 is bent into a bottom tube 112 and a vertical tube 113, and the vertical tube 113 is connected to the armrest tube 111 through an inclined tube 117, ensuring the stability of the frame. The seat tube is connected to the bottom tube through the pedal tube, further ensuring the stability of the frame and also increasing the strength of the pedal tube. The seat tube is fixedly connected to the inclined tube. The bottom tube is fixedly connected with multiple fixed tubes 116 buried underground, ensuring the stability of the frame fixed on the ground.

[0035] The first rotating shaft is connected with a first damper. When the user uses the hand-cranked vehicle function, both hands grip the first handle and the second handle, driving the first rotating shaft to rotate. The first damper can provide resistance for the rotation of the first rotating shaft, that is, provide resistance for the hand-cranked vehicle function. When the user uses the upright vehicle function, since the first damper provides resistance for the first rotating shaft, it can also prevent the first armrest support tube and the second armrest support tube from rotating when the user holds the first armrest support tube and the second armrest support tube with both hands, ensuring the safety of the upright vehicle function.

[0036] The first hand-cranking mechanism includes a first connecting seat, a first armrest support tube, and a first handle. The first connecting seat is detachably and fixedly connected to one end of the first rotating shaft. It can be, but is not limited to, that the first connecting seat and the first rotating shaft are detachably and fixedly connected through bolts, facilitating the disassembly and assembly of the first connecting seat and the first rotating shaft. The first armrest support tube is rotatably connected to the first connecting seat. The first armrest support tube rotates relative to the first connecting seat, and can change the angle between the first armrest support tube and the first rotating shaft. When using the hand-cranked vehicle function, the first armrest support tube can be rotated to be perpendicular to the first rotating shaft; when using the upright vehicle function, the first armrest support tube can be rotated to be coaxial with the first rotating shaft. A first sliding rod is slidably connected inside the first armrest support tube, the first handle is rotatably connected to the first sliding rod, and a first locking mechanism is arranged between the first armrest support tube and the first connecting seat. When the first locking mechanism is in the locked state, the first armrest support tube cannot rotate relative to the first connecting seat; when the first locking mechanism is in the unlocked state, the first armrest support tube can rotate relative to the first connecting seat, and the first locking mechanism can fix the relative position of the first armrest support tube and the first connecting seat. By pulling the first handle outwards, the first sliding rod can be driven to slide inside the first armrest support tube. The sliding of the first armrest support tube drives the first locking mechanism to switch to the unlocked state, and the first armrest support tube can rotate relative to the first connecting seat. The first armrest support tube can be rotated to be perpendicular to the first rotating shaft or coaxial with the first rotating shaft. After the first armrest support tube rotates in place, release the first handle, and the first sliding rod resets, causing the first locking mechanism to switch to the locked state. The first armrest support tube cannot rotate relative to the first connecting seat, and the first locking mechanism fixes the relative position of the first armrest support tube and the first connecting seat.

[0037] The second hand-cranking mechanism includes a second connecting seat, a second armrest support tube, and a second handle. The second connecting seat is detachably and fixedly connected to one end of the second rotating shaft. It can be, but is not limited to, that the second connecting seat and the second rotating shaft are detachably and fixedly connected by bolts, which facilitates the disassembly and assembly of the second connecting seat and the second rotating shaft. The second armrest support tube is rotatably connected to the second connecting seat. The second armrest support tube rotates relative to the second connecting seat, and the angle between the second armrest support tube and the second rotating shaft can be changed. When using the hand-cranking vehicle function, the second armrest support tube can be rotated to be perpendicular to the second rotating shaft; when using the upright vehicle function, the second armrest support tube can be rotated to be coaxial with the second rotating shaft. A second sliding rod is slidably connected inside the second armrest support tube, the second handle is rotatably connected to the second sliding rod, and a second locking mechanism is provided between the second armrest support tube and the second connecting seat. When the second locking mechanism is in the locked state, the second armrest support tube cannot rotate relative to the second connecting seat; when the second locking mechanism is in the unlocked state, the second armrest support tube can rotate relative to the second connecting seat, and the second locking mechanism can fix the relative position of the second armrest support tube and the second connecting seat. By pulling the second handle outwards, the second sliding rod can be driven to slide inside the second armrest support tube, and the sliding of the second armrest support tube drives the second locking mechanism to switch to the unlocked state. The second armrest support tube can rotate relative to the second connecting seat, and the second armrest support tube can be rotated to be perpendicular to the second rotating shaft or coaxial with the second rotating shaft. After the second armrest support tube rotates in place, release the second handle, and the second sliding rod resets, causing the second locking mechanism to switch to the locked state. The second armrest support tube cannot rotate relative to the second connecting seat, and the second locking mechanism fixes the relative position of the second armrest support tube and the second connecting seat.

[0038] When the hand-cranked upright vehicle is in the first usage state, that is, when using the upright vehicle function, the first armrest support tube, the first handle, the first rotating shaft, the second armrest support tube, and the second handle are coaxial. Under the action of the first damper, during the process of grasping the first armrest support tube and the second armrest support tube with both hands, the first armrest support tube and the second armrest support tube will not rotate. At this time, the first locking mechanism is in the locked state, and the first armrest support tube will not rotate relative to the first connecting seat; the second locking mechanism is in the locked state, and the second armrest support tube will not rotate relative to the second connecting seat, ensuring the safety of the upright vehicle function.

[0039] When the hand-cranked vertical bike is in the second usage state, that is, when using the hand-cranked bike function, the first armrest support tube is perpendicular to the first rotating shaft, the first handle is perpendicular to the first armrest support tube, the second armrest support tube is perpendicular to the first rotating shaft, the second handle is perpendicular to the second armrest support tube, and the first handle and the second handle are parallel. The first handle and the second handle are arranged in a staggered manner, and the user can hold the first handle and the second handle with both hands and drive the first rotating shaft to rotate through the first handle and the second handle. At this time, the first locking mechanism is in the locked state, and the first armrest support tube will not rotate relative to the first connecting seat; the second locking mechanism is in the locked state, and the second armrest support tube will not rotate relative to the second connecting seat, ensuring the safety of the hand-cranked bike function.

[0040] For the hand-cranked vertical bike of the present invention, by pulling the first handle to drive the first sliding rod to slide, the first locking mechanism is switched to the unlocked state, and the first armrest support tube can rotate relative to the first connecting seat to change the positions of the first armrest support tube and the first handle. Similarly, by pulling the second handle to drive the second sliding rod to slide, the second locking mechanism is switched to the unlocked state, and the second armrest support tube can rotate relative to the second connecting seat to change the positions of the second armrest support tube and the second handle. The positions of the first armrest support tube, the first handle, the second armrest support tube, and the second handle can be adjusted according to the training needs to meet the training requirements of the hand-cranked bike function and the vertical bike function. At the same time, it is also relatively convenient to switch the states of the first hand-cranking mechanism and the first hand-cranking mechanism, only requiring pulling and turning without excessive operations.

[0041] Figure 1 、 3 The first hand-cranking mechanism shown in FIGS. 5, 6, and 11 is in the first usage state of the hand-cranked vertical bike. At this time, the first armrest support tube, the first handle, and the first rotating shaft are coaxial, and the first positioning block is placed in the first positioning groove to prevent the first handle from rotating relative to the first armrest support tube.

[0042] Figure 1 、 3 The second hand-cranking mechanism shown in FIGS. 5, 6, and 12 is in the second usage state of the hand-cranked vertical bike. At this time, the second armrest support tube is perpendicular to the first rotating shaft, the second handle is perpendicular to the second armrest support tube, and the fourth positioning block is placed in the fourth positioning groove to prevent the second handle from rotating relative to the second armrest support tube.

[0043] Furthermore, the footrest 120 is rotatably connected to the frame 100 through a second rotating shaft, and the second rotating shaft is connected with a second damper.

When the user uses the upright bike function, the buttocks sit on the seat cushion, the feet step on the pedals, and the hands hold the first handrail support tube and the second handrail support tube.

[0046] In an embodiment of the present invention, the first rotating block is rotatably connected to the first connecting seat, realizing the rotational connection between the first handrail support tube and the first connecting seat. The first locking mechanism can be arranged inside the first rotating block to avoid the exposure of the first locking mechanism and ensure the use safety of the hand-cranked upright bike.

[0047] The first locking mechanism includes at least one first locking block. Optionally but not limited to, the first locking mechanism includes two symmetrically arranged first locking blocks, thus ensuring the reliability of the first locking mechanism in fixing the positions of the first armrest support tube and the first connecting seat. A first spring is sleeved on the first locking block. Under the elastic force of the first spring, the first locking block is pressed against the first wedge surface. If two first locking blocks are provided in the first locking mechanism, then two first wedge surfaces are provided on the first sliding rod. When the first sliding rod slides relative to the first armrest support tube, under the elastic force of the first spring, the first locking block will be pressed against the first wedge surface, and the first locking block will perform telescopic movement. Specifically, when the first sliding rod is pulled out and away from the rotation axis of the first rotating block, the first locking block will contract and disengage from the first locking hole on the first connecting seat, and the first armrest support tube can rotate relative to the first connecting seat.

Optionally but not limited to, the second locking mechanism includes two symmetrically arranged second locking blocks, so as to ensure the reliability of the second locking mechanism in fixing the positions of the second armrest support tube and the second connecting seat. A second spring is sleeved on the second locking block. Under the elastic force of the second spring, the second locking block is pressed against the second wedge surface. If the second locking mechanism is provided with two second locking blocks, the second sliding rod is provided with two second wedge surfaces. When the second sliding rod slides relative to the second armrest support tube, under the elastic force of the second spring, the second locking block will be pressed against the second wedge surface, and the second locking block will perform telescopic movement. Specifically, when the second sliding rod is pulled out and away from the rotation axis of the second rotating block, the second locking block will contract and disengage from the second locking hole on the second connecting seat, and the second armrest support tube can rotate relative to the second connecting seat. When the second sliding rod resets and approaches the rotation axis of the second rotating block, the second locking block will extend into the second locking hole on the second connecting seat, and the second armrest support tube cannot rotate relative to the second connecting seat. By controlling the second sliding rod to slide relative to the second armrest support tube with the second handle, the locking state of the second locking mechanism is switched, so as to adjust the position of the second armrest support tube, and the operation is simple.
