Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a fitness bike with adjustable handrails. Background Technology

[0002] Exercise bikes, a common type of fitness equipment, are typically equipped with a seat, handrails, and damped pedals. In actual use, users sit on the seat or stand up, hold the handrails, and alternately pedal with their legs to simulate cycling motions, thereby achieving the effect of exercising.

[0003] However, the handrail design of exercise bikes currently on the market has certain limitations. The handrail position of most exercise bikes cannot be adjusted flexibly, or the adjustment range is relatively limited, making it difficult to match different riding postures of users. Utility Model Content

[0004] The purpose of this invention is to provide an exercise bike with adjustable handrails, and the technical problem to be solved is how to adjust the position of the handrails.

[0005] To achieve the above objectives, the solution of this utility model is: an exercise bike with adjustable handrails, including a frame, a damped pedal assembly installed on the frame, and the frame including a base, handrails and support arms;

[0006] A seat is mounted on the base for people to sit on, and the seat allows them to pedal the damped pedal assembly after sitting on it.

[0007] The handrail includes a handrail frame and a handrail body. The handrail frame is located in front of the seat, with its bottom end hinged to the base and its top end extending upwards to allow for forward and backward swinging. The handrail body is located on the upper part of the handrail frame for the user to hold onto when pedaling the damped foot pedal assembly.

[0008] The top of the support arm is hinged to the handrail frame, and the base has a movable part that slides back and forth. The bottom of the support arm is hinged to the movable part of the base so that the end of the support arm can slide through the movable part, thereby linking the handrail frame to swing back and forth, so that the main body of the handrail moves with the handrail frame.

[0009] Furthermore, the base includes a fixed frame and a movable frame;

[0010] The seat is mounted on a fixed frame, the bottom of the armrest frame is hinged to the fixed frame, and the movable frame is mounted at the front of the fixed frame, located below the armrest, and can move back and forth relative to the fixed frame and be positioned in multiple positions.

[0011] The bottom end of the support arm is hinged to the movable frame. The position on the movable frame where the support arm is hinged is the movable part. The bottom end of the support arm moves back and forth with the movable frame.

[0012] Furthermore, the top of the handrail is tilted forward, so that when the handrail swings forward, the handrail body moves forward and lowers, and when the handrail swings backward, the handrail body moves backward and rises.

[0013] Furthermore, the fixed frame is used to rest on the ground, and the movable frame extends forward from the fixed frame, also for resting on the ground.

[0014] Furthermore, the hinge point between the support arm and the handrail is located above and behind the hinge point between the support arm and the movable frame, so that when the movable frame moves forward, it causes the handrail to swing forward, and when the movable frame moves backward, it causes the handrail to swing backward.

[0015] Furthermore, the bottom side of the movable frame is rotatably mounted with rollers, which rest on the ground to support the movable frame and roll back and forth when the movable frame moves back and forth.

[0016] Furthermore, the bottom end of the handrail is pivotally connected to the fixed frame.

[0017] Furthermore, a drive mechanism is provided, which is located between the fixed frame and the movable frame, and is used to drive the movable frame to move back and forth.

[0018] Furthermore, the damping pedal assembly is mounted on a fixed frame and includes a pivot, a damping mechanism, a left crank, a right crank, a left pedal, and a right pedal. The pivot extends laterally to the left and right and is capable of rotating around the pivot. The damping mechanism is drivenly connected to the pivot to provide damping for the pivot's rotation around the pivot. One end of the left crank is connected to the left end of the pivot, and one end of the right crank is connected to the right end of the pivot, so that the left crank, right crank, and pivot are connected to form a Z-shape. The left pedal is laterally pivotally connected to the other end of the left crank, and the right pedal is laterally pivotally connected to the other end of the right crank. The left pedal is for left foot pedaling, and the right pedal is for right foot pedaling.

[0019] Furthermore, the handrail frame is telescopic and can be positioned at multiple lengths to drive the handrail body to rise and fall through telescopic movement.

[0020] An exercise bike with adjustable handlebars includes a frame with damped pedal assembly mounted on the frame, and the frame includes a base, handlebars and support arms.

[0021] A seat is mounted on the base for people to sit on, and the seat allows them to pedal the damped pedal assembly after sitting on it.

[0022] The handrail includes a handrail frame and a handrail body. The handrail frame is located in front of the seat, with its bottom end hinged to the base and its top end extending upwards to allow for forward and backward swinging. The handrail body is located on the upper part of the handrail frame for the user to hold onto when pedaling the damped foot pedal assembly.

[0023] The handrail has a movable part that slides along the handrail. The top of the support arm is hinged to the movable part, and the bottom is hinged to the base. The movable part drives the end of the support arm to slide, thereby linking the handrail to swing back and forth, so that the main body of the handrail moves with the handrail.

[0024] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0025] (1) The handrail is located in front of the seat, with its bottom end hinged to the base and its top end extending upwards to allow for back-and-forth rotation. The handrail body is located on the upper part of the handrail for people to hold when pedaling the damping pedal assembly. One end of the support arm is hinged to the handrail and the other end is hinged to the base. The handrail has a movable part that slides along the handrail, and the support arm is hinged to the movable part of the handrail, or the base has a movable part that slides back and forth, and the support arm is hinged to the movable part of the base. The handrail can be moved back and forth by sliding the end of the support arm through the movable part, so that the handrail can be rotated back and forth, and the position of the handrail body can be adjusted by moving the handrail with the handrail.

[0026] (2) The top of the handrail is tilted forward so that when the handrail swings forward, the main body of the handrail moves forward and lowers. At this time, the main body of the handrail is farther away from the user and is lower in position. The user can sit on the seat and hold the main body of the handrail with a large forward lean, or lie on the main body of the handrail and pedal the damping pedal assembly. When the handrail swings backward, the main body of the handrail moves backward and rises. At this time, the main body of the handrail is closer to the user and is higher in position. The user can sit on the seat with a more upright posture and hold the main body of the handrail to pedal the damping pedal assembly, or stand up and hold the main body of the handrail to pedal the damping pedal assembly. This allows for easy changes in the user's riding posture and increases the diversity of exercise.

[0027] (3) The fixed frame is used to rest on the ground, and the movable frame extends forward from the fixed frame and is also used to rest on the ground, so that the movable frame and the fixed frame together form the base of the exercise bike. The hinge point between the support arm and the handrail is located above and behind the hinge point between the support arm and the movable frame, so that when the movable frame moves forward, it drives the handrail to swing forward, and when the movable frame moves backward, it drives the handrail to swing backward. Thus, when the exercise bike is not in use, the movable frame can be moved backward as much as possible, and the linked handrail can also move backward, shortening the overall length in the front-back direction, thus saving more space.

Detailed Implementation

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiments of the invention will now be described in full with reference to the accompanying drawings. It should be noted that the invention may be implemented in various forms and is not limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] This utility model provides an exercise bike with adjustable handrails, such as... Figure 1-6 As shown, the vehicle includes a frame 1, which includes a base 10, a handlebar 7, and a support arm 5.

[0038] The frame 1 is equipped with a damping pedal assembly 2. The damping pedal assembly 2 can adopt the corresponding structure of any existing exercise bike and can be installed on any part of the frame 1. The base 3 is equipped with a seat 6 for the user to sit on. After sitting, the user pedals the left pedal 17 with the left foot and the right pedal 18 with the right foot to pedal the damping pedal assembly 2, simulating the riding action of a bicycle. Of course, the user can also pedal the damping pedal assembly 2 in a standing position instead of sitting on the seat 6. The handlebar 7 includes a handlebar frame 8 and a handlebar body 9. The handlebar frame 8 is located in front of the seat 6 and its bottom end is hinged to the base 3. The handlebar body 9 is located on the upper part of the handlebar frame 8 and is used to hold the damping pedal assembly 2 when the user pedals (including pedaling the damping pedal assembly while sitting on the seat or standing). The back and forth swing of the handlebar frame 8 will change the position of the handlebar body 9 to match the different riding postures of the user.

[0039] In Example 1:

[0040] like Figure 1-5 As shown, the base 10 includes a fixed frame 3 and a movable frame 4. The damping pedal assembly 2 is mounted on the fixed frame 3, with a focus on... Figure 3 As shown, the fixing frame 3 includes a vertical rod 19 and a T-shaped seat 20 connected to the bottom end of the vertical rod 19, combined with... Figure 2 As shown, the specific damping pedal assembly 2 includes a pivot 13, a damping mechanism 14, a left crank 15, a right crank 16, a left pedal 17, and a right pedal 18. The pivot 13 extends laterally to the left and right, passing through the uprights 19 of the fixing frame 3, and is rotatably mounted on the uprights 19 to be able to rotate around the axis. The damping mechanism 14 can be any existing structure that can provide rotational damping, such as a magnetic damping wheel. The damping mechanism 14 is connected to the pivot 13 in a transmission manner. The transmission connection method is a conventional technical means in the field and will not be described in detail. As long as it can provide damping for the rotation of the pivot 13 around the axis, it is acceptable. One end of the left crank 15 is connected to the left end of the pivot 13, and one end of the right crank 16 is connected to the right end of the pivot 13, so that the left crank 15, the right crank 16, and the pivot 13 are connected to form a Z-shape. The left pedal 17 is laterally pivotally connected to the other end of the left crank 15, and the right pedal 18 is laterally pivotally connected to the other end of the right crank 16.

[0041] Specifically in this embodiment, the seat 6 is mounted on the mounting bracket 3, more specifically on the top of the upright 19 of the mounting bracket 3;

[0042] In this embodiment, the handrail 7 is specifically hinged to the fixed frame 3. The top of the handrail frame 8 extends upward and can swing back and forth around the hinge point. Preferably, the bottom of the handrail frame 8 is pivotally connected to the fixed frame 3 through a horizontally placed pivot. Of course, the handrail frame 8 can also be configured to be connected to the fixed frame 3 in a hinged connection manner that can swing back and forth as well as swing left and right. That is, it is not limited to the pivot connection method.

[0043] The top end of the support arm 5 is hinged to the handrail frame 8, and the bottom end is hinged to the base 3. The base 3 has a movable part 22 that slides back and forth. The support arm 5 is hinged to the movable part 22 of the base 3. The specific position of the hinge point is not limited. Those skilled in the art can set it according to actual needs. As long as the end of the support arm 8 can slide through the movable part 22 to link the handrail frame 8 to swing back and forth, so that the handrail body 9 moves with the handrail frame 8.

[0044] Preferably, in this embodiment, the movable frame 4 is installed in front of the fixed frame 3, located below the handrail 7, and can move back and forth relative to the fixed frame 3 and be positioned in multiple positions. The positioning can be stepless or stepped. The bottom end of the support arm 5 is hinged to the movable frame 4 and moves back and forth with the movable frame 4. The position where the support arm 5 is hinged on the movable frame 4 is the movable part 22. The top end of the support arm 5 is hinged to the handrail frame 8, so that the back and forth movement of the movable frame 4 can link the support arm 5 and drive the handrail frame 8 to swing back and forth. When the movable frame 4 is positioned in different positions, the handrail frame 8 is positioned in different positions accordingly. Thus, by moving the movable frame 4, the position of the handrail body 9 can be adjusted. The adjustment range is large and the operation is convenient.

[0045] In a preferred embodiment, the top of the handrail frame 8 is tilted forward, so that when the handrail frame 8 swings forward, the handrail body 9 moves forward and lowers. At this time, the handrail body is farther away from the user and at a lower position, allowing the user to sit on the seat and grip the handrail body with a significant forward lean, or lie on the handrail body to pedal the damping pedal assembly. When the handrail frame 8 swings backward, the handrail body 9 moves backward and rises, bringing the handrail body closer to the user and at a higher position. At this time, the user can sit on the seat with a more upright posture and grip the handrail body to pedal the damping pedal assembly, or stand and grip the handrail body to pedal the damping pedal assembly, facilitating changes in the user's riding posture and increasing the diversity of exercise.

[0046] The fixed frame 3 is used to rest on the ground, and the movable frame 4 extends forward from the fixed frame 3, also used to rest on the ground, so that the movable frame 4 and the fixed frame 3 together form the base 10 of the exercise bike. In a more specific embodiment, the T-shaped seat 20 of the fixed frame 3 is parallel to the ground, and the horizontal arm of the T-shaped seat 20 extends to the left and right and is located on the rear side, while the vertical arm extends forward and backward and is located on the front side. The movable frame 8 is also a T-shaped structure, but the horizontal arm of the T-shape is located on the front side, and the vertical arm is located on the rear side, and it slides into the T-shaped vertical arm of the fixed frame 9 to realize the forward and backward displacement of the movable frame 4 relative to the fixed frame 3. Preferably, the fixed frame 3 is equipped with a support leg 21 on its bottom side, which supports the ground. The movable frame 4 is rotatably equipped with a roller 11 on its bottom side, which rests on the ground, supports the movable frame 4, and rolls forward and backward when the movable frame 4 moves forward and backward. More preferably, the hinge point between the support arm 5 and the handrail 8 is located above and behind the hinge point between the support arm 5 and the movable frame 4, so that when the movable frame 4 moves forward, it causes the handrail 8 to swing forward, and when the movable frame 4 moves backward, it causes the handrail 8 to swing backward. Thus, when the exercise bike is not in use, the movable frame 4 can be moved as far back as possible, and the handrail 8 will also move backward, shortening the overall length of the exercise bike in the front-back direction and saving more space.

[0047] Specifically, a drive mechanism 12 is also provided. The drive mechanism 12 is located between the fixed frame 3 and the movable frame 4 and is used to drive the movable frame 4 to move back and forth. The specific structure is not limited. Preferably, the drive mechanism 12 is an electric telescopic rod, one end of which is connected to the fixed frame 3 and the other end is connected to the movable frame 4. The movable frame 4 is moved back and forth by telescopic movement. When the telescopic rod stops telescopic, the movable frame and the handrail are positioned.

[0048] To make the structure more stable, in a preferred embodiment, the movable frame 4 and the support arm 5 are located directly below the handrail frame 8. The top end of the support arm 5 is pivotally connected to the handrail frame 8 via a left-right extending pivot, and the bottom end is pivotally connected to the movable frame 4 via a left-right extending pivot.

[0049] In order to facilitate direct adjustment of the handrail height, in a preferred embodiment, the handrail frame 8 is telescopically oriented and can be positioned at multiple lengths so as to drive the handrail body 9 to rise and fall through telescopic movement.

[0050] In Example 2:

[0051] like Figure 6 As shown, the handrail frame 8 has a movable part 22 that slides along the handrail frame 8. The top end of an arm 5 is hinged to the movable part 22, and the bottom end is hinged to the base 3. The movable part 22 drives the end of the arm 8 to slide, thereby linking the handrail frame 8 to swing back and forth, so that the handrail body 9 moves with the handrail frame 8. It can be understood that the preferred options and specific structures in Embodiment 1 are also applicable to Embodiment 2. Therefore, they will not be described again in Embodiment 2.

[0052] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
