A footrest tension device

Abstract

This application discloses a foot pedal tensioning device, including a handle, a foot pedal, and an elastic cord. The handle includes a handle connector; the foot pedal includes a foot pedal connector; the elastic cord is folded in half, with both ends fixed to the foot pedal connector, and the handle connector threaded through the waist of the elastic cord. When the elastic cord is stretched and one end detaches from the foot pedal connector, the elastic cord retracts towards the other end on the foot pedal connector via the handle connector. By folding the elastic cord in half, fixing the ends to the foot pedal connector, and attaching the waist to the handle connector, when one end detaches from the foot pedal connector, the elastic cord retracts towards the other end on the foot pedal connector until it returns to its natural elongated state. The contraction force of the elastic cord during contraction can counteract the rebound force, thereby preventing the elastic cord from rebounding instantaneously when stretched and the end detaches from the foot pedal connector, which could injure the user's eyes or other vital areas.

Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a foot pedal pulling device. Background Technology

[0002] The leg pedal resistance band is a simple and efficient fitness device, mainly composed of elastic ropes, handles, and pedals. Its operating mechanism is based on the elastic deformation of the elastic ropes to provide reaction force. When the user performs stretching or pedaling movements, they encounter elastic resistance generated by the elastic ropes, thus achieving the purpose of muscle training. This device can train multiple parts of the body, including the arms, legs, waist, and back, helping to increase muscle strength, improve flexibility, improve posture, and promote fat loss. The leg pedal resistance band is suitable for users of different ages and fitness levels. Beginners can choose models with lower resistance, while users with some fitness experience can choose more advanced models. With its compact size, high safety, adjustable resistance, and high cost-effectiveness, this device has become an economical fitness tool.

[0003] In current technology, common foot-pedal resistance band designs typically have one end of the elastic cord fixed to the upper handle and the other end fixed to the lower pedal. However, in practical applications, this connection method presents potential safety risks. For example, the connection may lack stability; if the elastic cord on the pedal breaks or accidentally detaches, it will quickly rebound towards the user, potentially striking sensitive areas such as the eyes, causing serious and irreversible injury. Therefore, current foot-pedal resistance bands have significant issues regarding safety and reliability, urgently requiring design improvements to address and perfect their design. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a foot pedal pulling device.

[0005] The technical solution adopted by this utility model is as follows: This application provides a foot pedal pulling device, including a handle, a foot pedal, and an elastic rope; The handle includes a handle connector and a handle portion, with the handle portion disposed on both sides of the handle connector; The pedal includes a pedal connector and a pedal part, with the pedal part disposed on both sides of the pedal connector; The elastic rope is folded in half, and the two ends of the elastic rope are fixed to the foot pedal connector. The handle connector is threaded through the waist of the elastic rope. When the elastic cord is stretched and one end of the cord detaches from the pedal connector, the elastic cord retracts through the handle connector toward the other end of the cord on the pedal connector.

[0006] By folding the elastic cord in half, with one end fixed to the pedal connector and the other end attached to the handle connector, when one end detaches from the pedal connector, the elastic cord does not rebound directly towards the handle. Instead, it contracts towards the other end of the cord on the pedal connector through the handle connector until it returns to its natural elongation. The contraction force of the elastic cord can offset most of the rebound force (reducing the rebound force), thus preventing a sudden rebound when the elastic cord is stretched and detaches from the pedal connector, which could injure the user's eyes or other vital areas. In actual use, even if a small rebound occurs, it happens on the side of the handle away from the user's eyes or other vital areas, preventing irreversible serious injury.

[0007] In an optional embodiment, the handle connector includes a connecting body and a movable connector; The connecting body has a mounting cavity, the movable connector is disposed in the mounting cavity and forms a mounting channel with the connecting body, the mounting channel being U-shaped; The waist of the elastic rope is located on the installation channel, and when the elastic rope is stretched, the waist of the elastic rope abuts against the movable connector. The connecting body has a pull rope channel on the side near the foot pedal. The pull rope channel is connected to the installation channel, and the elastic rope passes through the pull rope channel and exits the connecting body.

[0008] In an optional embodiment, the inner wall of the mounting cavity of the connecting body has a groove, and the movable connector has a sliding corner post, which is slidably disposed in the groove, so that the movable connector is slidably disposed in the mounting cavity of the connecting body.

[0009] In an optional embodiment, the connecting body is further fixedly connected to a limiting cover, and the limiting cover is located at the end of the slide groove away from the elastic rope, the limiting cover restricting the sliding corner post from sliding out of the slide groove; The end of the chute near the elastic rope has a limiting part, which restricts the sliding corner post from sliding out of the chute.

[0010] In an optional embodiment, the inner wall of the mounting cavity of the connecting body is further provided with a first connecting post, the connecting post having a threaded hole; The limiting cover is fixed to the connecting body by fasteners; The limiting cover has a second connecting post with a through hole, and fasteners fix the limiting cover to the connecting body through the through hole and the threaded hole.

[0011] In an optional embodiment, the pedal pulling device further includes an elastic element; The elastic element is disposed between the connecting body and the movable connector; When the elastic cord is stretched and the movable connector moves toward the pedal, the elastic element is in a compressed state. When the tensioned elastic cord is released, the elastic element returns to its natural state, causing the movable connector to reset.

[0012] In an optional embodiment, a counter is also included, wherein a counting button is provided on the counter, and the counter counts once when the counting button is pressed once; The limiting cover of the connecting body is also provided with a first pressing spring, which is correspondingly provided with the counting button; The movable connector is also provided with a second pressing spring, which is corresponding to the first pressing spring; When the movable connector moves towards the pedal side under the tension of the elastic rope, the second pressing spring cooperates with the first pressing spring and presses the first pressing spring against the counting button, causing the counter to count once.

[0013] In an optional embodiment, the first pressing spring includes a first spring body, the first spring body is fixed on the limiting cover, the first spring body is provided with a first protrusion, and the position where the first protrusion connects with the first spring body has a first guide slope. The second pressing spring includes a second spring body, which is fixed on the movable connector, and a second protrusion is provided on the second spring body; The first spring body is provided with a corresponding second protrusion to the second pressing spring; The second spring body is provided corresponding to the first protrusion of the first pressing spring; When the movable connector moves toward the side closer to the foot pedal, the second protrusion causes the first pressing spring to move toward the side closer to the counting button via the first guide slope.

[0014] In an optional embodiment, the position where the second protrusion connects to the second spring body has a second guide slope, which is provided corresponding to the first guide slope.

[0015] The second guide slope allows the first pressing spring to press the counting button more smoothly. Furthermore, when the tension rope is removed and the movable connector moves away from the pedal, the second guide slope allows the second pressing spring to reset.

[0016] In an optional embodiment, the counter is further connected to a display screen for displaying the count value; The counter is mounted on the limiting cover or on the connecting body.

[0017] The beneficial effects of this utility model are: (1) By folding the elastic cord in half, fixing the cord end to the pedal connector and hanging the cord waist on the handle connector, when one cord end detaches from the pedal connector, the elastic cord does not rebound directly towards the handle side. Instead, it contracts towards the other cord end on the pedal connector through the handle connector until it returns to its natural elongation. The contraction force of the elastic cord can offset most of the rebound force (reducing the rebound force), thus avoiding the instantaneous rebound phenomenon when the elastic cord is stretched and the cord end detaches from the pedal connector, which could injure the user's eyes or other vital parts. In actual use, even if a small rebound occurs, it will occur on the side of the handle away from the user's eyes or other vital parts, and will not cause irreversible serious injury to the user.

[0018] (2) This application slides the movable connector onto the connecting body. When the movable connector moves towards the foot pedal under the tension of the elastic rope, the second pressing spring causes the first pressing spring to press against the counting button, enabling the counter to perform one count. Simultaneously, the counting result is displayed on the screen, thereby improving the real-time performance and display of the counting, and enhancing the user experience. Furthermore, the counting structure is simple and flexible, reducing production costs compared to counting using sensors or other components. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-7 As shown, this application provides a foot pedal pulling device, including a handle 100, a foot pedal 200, and an elastic rope 300; The handle 100 includes a handle connector 10 and handle portions 20 disposed on both sides of the handle connector 10; The pedal 200 includes a pedal connector 210 and pedal portions 220 disposed on both sides of the pedal connector 210; The elastic rope 300 is folded in half, and the two ends 310 of the elastic rope 300 are fixed to the foot pedal connector 210. The handle connector 10 of the handle 100 is threaded through the waist 320 of the elastic rope 300. When the elastic cord 300 is stretched and one of its ends 310 is detached from the pedal connector 210, the elastic cord 300 retracts through the handle connector 10 toward the other end 310 on the pedal connector 210.

[0023] By folding the elastic cord 300 in half (half-fold configuration), with the cord end 310 fixed to the foot pedal connector 210 and the cord waist 320 hanging on the handle connector 10 of the handle 100, when one cord end 310 detaches from the foot pedal connector 210, the elastic cord 300 does not rebound directly towards the handle 100. Instead, it contracts towards the other cord end 310 on the foot pedal connector 210 through the handle connector 10 until it returns to its natural elongation. The contraction force of the elastic cord 300 can offset most of the rebound force (reducing the rebound force), thus preventing the elastic cord 300 from experiencing a sudden rebound when the cord end 310 detaches from the foot pedal connector 210 while under tension, which could injure the user's eyes or other vital areas. In actual use, even if a small rebound occurs, it will happen on the side of the handle 100 away from the user's eyes or other vital areas, and will not cause irreversible serious injury to the user.

[0024] In this embodiment, the handle connector 10 includes a connecting body 110 and a movable connector 120; The connecting body 110 has a mounting cavity 111, and the movable connector 120 is disposed in the mounting cavity 111 and forms a mounting channel with the connecting body 110.
