Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a forward bending device. Background Technology

[0002] The sit-and-reach test is a physical fitness test item for primary, secondary, and tertiary schools. Its purpose is to measure the range of motion that the trunk, waist, hip, and other joints can achieve in a static state. It mainly reflects the extensibility and elasticity of the joints, ligaments, and muscles in these areas, as well as the development level of the body's flexibility.

[0003] Currently, the sit-and-reach devices used in training are generally divided into two types: one without a seat cushion, which requires the main body to be against a wall to prevent displacement in order to be used normally; and the other with a seat cushion, which overcomes the problem that the main body must be against a wall to be used normally. However, in actual training, users need to get up from the seat cushion to view and operate the scale to check their training results and reset the scale that records the results, which greatly reduces the user's training efficiency. In addition, the sit-and-reach device with a seat cushion is larger in size, making it inconvenient to store and transport.

[0004] Therefore, the applicant hereby proposes a forward bending device. Utility Model Content

[0034] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0035] Example 1:

[0036] like Figure 1-8 As shown, a forward bending device of the present invention includes a base 1, a seat cushion assembly 2 and a measuring assembly 3; the base 1 is connected to the seat cushion assembly 2, and the measuring assembly 3 is longitudinally disposed on the top of the base 1; the seat cushion assembly 2 includes a soft membrane pad 21, and the connecting end of the soft membrane pad 21 is connected to the front side of the base 1.

[0037] The seat cushion assembly 2 also includes a take-up roller 22; the take-up roller 22 is laterally rotatably mounted on the rear side of the base 1, and a take-up opening 11A is provided at the lower front side of the base 1. The connecting end of the soft film pad 21 passes through the take-up opening 11A and is connected to the take-up roller 22. A blocking member 211 is provided on the non-connecting end of the soft film pad 21, including but not limited to blocking buckles or blocking strips. In this embodiment, a blocking buckle is preferred to avoid the problem of the soft film pad being completely stored on the take-up roller through the take-up opening; thus realizing the function of integrated storage of the soft film pad and the base; when idle, the take-up roller is rotated to drive the soft film pad to be wound around the take-up roller for storage; when in use, the non-connecting end of the soft film pad can be pulled out to unfold it for use.

[0038] The measuring component 3 includes a measuring ruler 31 and a reading plate 32. The measuring ruler 31 is longitudinally disposed on the upper surface of the base 1. The reading plate 32 is sleeved on the outer surface of the measuring ruler 31 and slides with it. There is a certain damping between the contact surfaces of the reading plate 32 and the measuring ruler 31 to prevent the reading plate 32 from moving randomly during use. The upper surface of the measuring ruler 31 is provided with a scale. When using this forward bending device for training, the soft membrane pad and the base work together to allow the user to complete the forward bending training independently. The user can quickly check the training results without getting up or needing help from others. The reading plate can also be quickly reset to the starting point of the measuring ruler, which greatly improves the training efficiency.

[0039] The measuring component 3 also includes an L-shaped adjustment bracket 33. The top surface of the mounting end of the adjustment bracket 33 is bolted to the bottom surface of the measuring ruler 31. The adjustment end of the adjustment bracket 33 has a plurality of stroke holes 331 sequentially opened along its length. The base 1 has an adjustment hole 12A and a locking bolt 13A threadedly connected to the stroke hole 331. The adjustment hole 12A and the stroke hole 331 are preferably oblong holes. The height of the measuring ruler can be customized and locked by the cooperation of the locking bolt, the adjustment hole and the stroke hole.

[0040] The base 1 has a vertical mounting groove 14 on its rear side corresponding to the adjustment hole 12A for assembling the adjustment bracket 33; this improves the installation stability of the adjustment bracket and avoids the problem of the adjustment bracket tilting to the left or right during adjustment.

[0041] The soft membrane pad 21 is made of a soft material with certain flexibility and wear resistance, and the thickness of the soft membrane pad 21 is 0.1-20 mm; it avoids the problem of easy breakage due to friction during use, and is also easy to store.

[0042] The bottom surface of the soft membrane pad 21 is on the same horizontal plane as the bottom surface of the base 1, and the outer surface of the soft membrane pad 21 is coated with an antibacterial coating, which gives it a certain antibacterial property and makes it easy to disassemble and clean.

[0043] Both ends of the measuring ruler 31 are fitted with protective sleeves 311, which are made of soft material, preferably protective cotton in this embodiment.

[0044] Example 2:

[0045] The seat cushion assembly 2 includes a soft membrane pad 21 and a connecting slider 23; the connecting end of the soft membrane pad 21 is connected to the connecting slider 23, and the lower front side of the base 1 is provided with a horizontal mounting groove 15 that is slidably installed with the connecting slider 23; so that the soft membrane pad and the base can be detachably connected, making it easy to remove and clean.

[0046] Example 3:

[0047] The top surface of the soft membrane pad 21 has multiple stacking slots 24 that are equidistantly spaced laterally, which facilitates the stacking and storage of the soft membrane pads.

[0048] The base 1 has foot indicator marks on its front side, which may be printed, engraved or pasted, etc. In this solution, engraving is preferred to guide the correct placement of the feet.

[0049] Example 4:

[0050] like Figure 12-13 As shown, the base 1 includes a base plate 11, a foot support plate 12, and a folding frame 13. The foot support plate 12 is vertically positioned above the front end of the base plate 11. A winding opening 11A is formed between the contact surfaces of the foot support plate 12 and the base plate 11. The winding roller 22 is laterally rotatably positioned on the rear side of the base plate 11. The folding frame 13 is positioned between the base plate 11 and the foot support plate 12. Installing one folding frame 13 can achieve a stable vertical position between the foot support plate 12 and the base plate 11 while also allowing for folding. In this embodiment, two folding frames 13 are provided to ensure even force distribution on the foot support plate 12.

[0051] The folding frame 13 includes a fixed plate 131, a folding plate 132, and a support rod 133. The fixed plate 131 and the folding plate 132 are respectively disposed on the base plate 11 and the foot support plate 12. The fixed plate 131 and the folding plate 132 are rotatably connected at their proximal ends. The folding plate 132 is provided with a vertically shaped groove 1321. The support rod 133 is rotatably connected to the fixed plate 131. The non-rotating end of the support rod 133 is slidably engaged with the groove 1321. By pulling the non-rotating end of the support rod out of the lower notch of the C-shaped groove and sliding it upward along the C-shaped groove to engage with the upper notch, the foot support plate will rotate inward along its rotating end, thus completing the folded storage state of the base plate and foot support plate. Conversely, by pulling the non-rotating end of the support rod out of the upper notch of the C-shaped groove and sliding it downward along the C-shaped groove to engage with the lower notch, the foot support plate will rotate outward along its rotating end, thus completing the unfolded use state of the base plate and foot support plate.

[0052] The measuring component 3 also includes a folding frame 13 (the specific structure is the same as described above, and will not be repeated here, the difference being the installation position); the fixing plate 131 and the folding plate 132 are respectively located on the front side of the top of the foot support plate 12 and the bottom surface of the measuring ruler 31; the measuring component and the foot support plate can be switched between the folded storage state and the unfolded use state.

[0053] Working principle: The user sits on the soft mat, straightens their legs and presses them against the front side of the base. Then, the user touches the reading plate directly with their hand until it can no longer be pushed, and then retracts their arm. The reading plate will stop at the corresponding mark on the measuring scale. When the user wants to check their training results, they do not need to get up. They can simply press their feet against the soft mat to pull the base in front of them. The user can clearly see their training results. After checking the results, the user can directly reset the reading plate to the starting point of the measuring scale. Then, by pressing their feet against the front side of the base and straightening their legs, they can quickly start the next training session.

[0054] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
