Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a starting block with adjustable width. Background Technology

[0002] Starting blocks are common sports equipment used in track and field to assist in starting. Current technology adjusts the support position by moving the pedals forward and backward using a multi-position adjustable structure. However, conventional structures cannot adjust the width of the pedals on the same pedal, or simply pull the pedal outward using the existing telescopic structure, while the actual support area of ​​the pedal remains constant. Therefore, they cannot perfectly match the width of each athlete's foot, resulting in low flexibility. Furthermore, because the surface of a synthetic running track is elastic, conventional starting blocks, when subjected to a backward thrust at the moment of starting, will experience a slight backward displacement due to the elasticity of the plastic, leading to insufficient stability.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5 This invention provides a technical solution: a width-adjustable starting block, comprising a starting block body, the starting block body including a base 1, a positioning component 5, and independent foot pedals 8. The base 1 has a slide rail 2 inside, and a bonding plate 3 is installed at both the front and rear ends of the base 1. The positioning component 5 is located at the bottom of the bonding plate 3, and is respectively installed on both sides of the front end of the bonding plate 3. A pin 30 is located at the bottom of the positioning component 5, and the pin 30 is directly embedded and fixed to the ground. A sliding mechanism 6 is installed on the side of the base 1, and an extension component 7 is located on the outer side of the sliding mechanism 6. The extension component 7 is connected to the sliding mechanism 6 via a main support rod 16 at its bottom end. An independent foot pedal 8 is installed on the top of the extension component 7, and the independent foot pedal 8 is formed by multiple pedals 26 arranged in parallel. A slot 12 is provided on one side of the sliding mechanism 6, and the sliding mechanism 6... The starting device is held in place by the slot 12 on the top shell of the base 1. The front end of the sliding mechanism 6 is provided with a stop 19, and a threaded post 14 is inserted inside the stop 19. The adjustable width starting device uses the base 1 to support and bind the independent foot pedals 8 on both sides. When in use, the entire starting device needs to be fixed in the initial preset position of the starting line by the positioning component 5 at the bottom. Therefore, the bottom clip 30 of the fixing component needs to be pre-fixed and installed under the ground at the bottom of the plastic track, and it does not need to be removed. After the starting device is used, the entire starting device can be lifted upwards to remove the base 1 and the attached structural parts. The bottom fixing part of the positioning component 5 can be left in the starting position for subsequent use. The sliding mechanism 6 can adjust the vertical movement of the independent foot pedals 8, while the extension component 7 can simultaneously adjust the horizontal movement and support width range of the independent foot pedals 8.

[0026] In this embodiment, the sliding mechanism 6 includes a slider 11 and a threaded post 14. A handwheel 10 is installed at the front end of the threaded post 14. The bottom end of the slider 11 is inserted into the interior of the slide rail 2. A sliding sleeve 15 is installed at the top of the slider 11. The slider 11 is partially movably connected to the extension assembly 7. The end of the threaded post 14 is embedded in the housing inside the base 1 through a bearing. There are two of each of the sliding mechanism 6, the threaded post 14, and the handwheel 10, which are respectively installed on both sides of the base 1. When adjusting the sliding mechanism 6, the handwheel 10 at the front end is rotated directly. The threaded post 14 drives the threaded tube 13 at the bottom end of the slider 11 to move horizontally, thereby driving the outer extension assembly 7 and the independent foot pedal 8 to move. This structure allows for adjustment before the start of the race according to the user's specific habits.

[0027] In this embodiment, the extension assembly 7 includes a main support rod 16 and a secondary support rod 21. The top of the slider 11 has a telescopic hole 4. One end of the main support rod 16 is screwed into the telescopic hole 4 via a threaded structure on its surface. A limit ring 17 is installed at the end of the main support rod 16. The pedal 26 is installed on the top of the secondary support rod 21. A clamping groove 25 is provided on the inner side of the limit ring 17. A clamping ring 24 is installed inside the clamping groove 25. A stop block 19 is provided on the top of the clamping ring 24. A connecting port 23 is installed on one side of the stop block 19. The secondary support rod 21 passes into the interior of the sliding sleeve 15. A pull rod 20 is installed at the rear end of the secondary support rod 21. A connector 22 is provided at the front end of the secondary support rod 21. The connector 22 passes into the interior of the connecting port 23, and the connector 22 and the connecting port 23 are connected. 3. The main support rod 16 is fixedly connected by a threaded structure. A handle 18 is installed at the end of the main support rod 16. The independent foot pedal 8 can be extended outward by the extension component 7, so as to freely adjust according to the distance between the user's two feet. The adjustment is more efficient. The double-layer support structure provides a stronger support effect, and each support arc plate 28 can remain stable without rotating. This increases flexibility without affecting stability. By rotating the handle 18 at the rear end of the extension component 7, the main support rod 16 is moved outward. The clamping ring 24 is pulled outward synchronously by the limiting ring 17, which in turn moves the auxiliary support rod 21. Therefore, the top pedal 26 also moves with the two support rods, realizing the function of synchronous adjustment. The two support rods simultaneously support and fix each pedal 26, improving stability.

[0028] In this embodiment, a fixing collar 27 is installed at the bottom end of the pedal 26. The bottom end of the fixing collar 27 is welded to the supporting arc plate 28 as a whole. The secondary support rod 21 passes through the fixing collar 27 at the bottom of each pedal 26 in sequence. The supporting arc plate 28 presses against the surface of the main support rod 16, and the supporting arc plate 28 has a semi-circular structure. Each pedal 26 is installed in alignment with each other. Multiple pedals 26 are arranged side by side to form an independent foot pedal 8. Each pedal 26 can be disassembled or added, so the independent foot pedals can be adjusted according to the width of the user's foot. The extension width of device 8 is adjustable, expanding its applicability. It is also simple and efficient to assemble and disassemble. When increasing or decreasing the number of pedals 26, simply rotate the pull rod 20 at the rear end and pull out the connector 22 at the front end from the connection port 23. At this time, the pedals 26 can be increased or decreased through the gap between the connector 22 and the connection port 23. The bottom support arc plate 28 is pressed directly on the main support rod 16. Through this support arc plate 28, it can work with the top fixing collar 27 to prevent the pedals 26 from flipping when starting to step on the pedals, ensuring that it can be flexibly assembled and disassembled while also having sufficient stability.

[0029] In this embodiment, the positioning component 5 includes a plug-in post 29 and a fixing interface 31. The bottom end of the fixing interface 31 is welded to the top of the clip 30 as a whole. A spring 32 is installed inside the fixing interface 31, and a dustproof block 33 is installed on the top of the spring 32. The top and bottom of the spring 32 are fixedly connected to the bottom end of the dustproof block 33 and the inner wall of the fixing interface 31, respectively. The top of the dustproof block 33 is concave downwards, and the side of the dustproof block 33 fits against the inner wall of the fixing interface 31. The positioning component 5 is provided at the bottom. By embedding the fixing interface 31 in the positioning component 5 into the bottom of the plastic track along with the clip 30, it can be directly used. The plug-in rod is inserted into the fixed interface 31 to achieve the effect of plug-in fixation. This structure allows for a rigid connection instead of the traditional anti-slip bonding connection during use, resulting in higher stability and avoiding damage to the plastic track body after frequent installation. During installation, since the clips 30 and the fixed interface 31 are installed underground, each plug-in post 29 can be directly inserted into the fixed interface 31 to fix the entire starting device. When not in use, the inside of the fixed interface 31 is sealed by the dustproof block 33 on top, which can effectively prevent external garbage and dust from accumulating inside the fixed interface 31, making subsequent cleaning easier and more convenient.
