Description
Technical Field
[0001] This utility model relates to the field of sports mat technology, and in particular to sports mats used for abdominal, spinal or trunk flexion exercises. Background Technology
[0002] Sit-ups, as a common exercise, offer benefits such as strengthening abdominal muscles, promoting fat burning, improving body stability, enhancing cardiovascular function, and sculpting the body. Seated forward bends, on the other hand, improve flexibility, strengthen core muscles, promote blood circulation, and increase joint mobility. Beginners to sit-ups often require external assistance to press down on their lower limbs to prevent them from lifting their legs and failing to complete the movement. Traditionally, this requires a training partner to help hold down the lower limbs. Beginners to seated forward bends need to perform a sufficient degree of forward bend and hold the position for about 10 seconds to achieve a higher level of forward bend. Traditionally, this requires a training partner to provide continuous traction in front of the trainee. Both of these sports are currently major components of youth physical education courses. However, in reality, not every exerciser can guarantee that they will have an assistant to accompany them during their exercise, which limits the exercise opportunities to the assistant's schedule. As a result, some sit-up and sit-and-reach exercise machines have emerged on the market, allowing exercisers to perform sit-ups and sit-and-reach exercises independently. However, it is obvious that both sets of equipment require their own storage space and also bring inconvenience to the exerciser when switching between different exercises. Utility Model Content
[0003] In view of at least one of the above-mentioned technical problems, this utility model provides a dual-purpose mat for sit-ups and lateral forward bends. Based on the characteristic that both sit-ups and lateral forward bends begin in a seated position, the front of the auxiliary mat is designed with a mechanism to assist in pressing down the lower limbs and to provide a gripping point for the upper limbs. This allows the user to independently perform sit-ups or seated forward bends as needed using a single device. The specific technical solution is as follows: A dual-purpose mat for sit-ups and lateral bending includes an anti-bending mat body and a lower limb height limiting frame. The rear part of the lower limb height limiting frame is fixedly connected to the front part of the anti-bending mat body at an obtuse angle. The front part of the lower limb height limiting frame includes a straight bar body, the bottom surface of which is a limiting curved surface. The height difference between the bottom surface of the limiting curved surface and the bottom surface of the anti-bending mat body is not less than 5cm and not more than 15cm. A forward bending positioning plate is centrally located on the lower limb height limiting frame. The forward bending positioning plate includes several traction anchors evenly arranged in a straight line.
[0004] In some embodiments of this disclosure, the anti-bending pad includes an elastic pad, the elastic pad being provided with a base frame, the base frame being a frame structure made of metal and / or hard plastic.
[0005] In some embodiments of this disclosure, the base frame includes two opposing support rods, with a distance of no more than 30 cm between the two support rods.
[0006] In some embodiments of this disclosure, the lower limb height limiting frame is a rectangular metal frame.
[0007] In some embodiments of this disclosure, a frame assembly is provided at the center of the rear of the lower limb height limiting frame. The frame assembly includes two opposing vertical plates, with a horizontal axis between the vertical plates. The bottom of the forward flexion positioning plate is provided with a positioning through groove I that mates with the horizontal axis and a positioning through groove II that mates with the straight bar.
[0008] In some embodiments of this disclosure, the positioning through groove I includes a wide groove opening downwards and rearwards, the bottom of which connects to an elongated groove I extending towards the front end; the positioning through groove II includes an inclined groove opening downwards and rearwards, the bottom of which connects to an elongated groove II extending towards the front end; the elongated groove I and the elongated groove II have the same length.
[0009] In some embodiments of this disclosure, two vertical plates are arranged in parallel, and the distance between the two vertical plates is not less than the thickness of the forward bending positioning plate and the difference in size is not greater than 2mm.
[0010] In some embodiments of this disclosure, a traction handle is also included, wherein the traction anchor is a traction groove disposed on the upper surface of the flexion positioning plate.
[0011] In some embodiments of this disclosure, the traction groove is a forward-opening inclined groove.
[0012] In some embodiments of this disclosure, the traction handle is at least one of a traction stick, a traction belt, or a traction rope.
[0013] Compared with existing technologies, the above-mentioned sit-up and lateral forward bend dual-purpose mat has the following beneficial effects: By setting up the lower limb height limit frame and the forward flexion positioning plate, this device can not only help the exerciser press down the legs to prevent the lower limbs from rising when performing sit-ups, but also help the exerciser provide a gripping position for the upper limbs to maintain the flexion state when performing seated forward flexion. It does not involve complex transmission mechanisms, is easy to assemble and store; has a low failure rate and is not easily damaged. Attached Figure Description

[0015] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. The component numbers used herein are merely for distinguishing the described objects and have no sequential or technical meaning. The term "connection" in this disclosure, unless otherwise specified, includes both direct and indirect connections. In the description of this application, it should be understood that the directional terms "up," "down," "front," "back," "vertical," "horizontal," "top," and "bottom," etc., indicate directional or positional relationships based on the appendix. Figure 1 The orientations or positional relationships shown are for ease of description only and are not intended to indicate or imply that the device or unit referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0016] As shown in the attached diagram. Figures 1 to 4 As shown, a dual-purpose mat for sit-ups and lateral forward bends is designed, comprising an anti-bending mat body 1 and a lower limb height limiting frame 2. The anti-bending mat body 1 has an anti-bending structure to prevent significant bending deformation, ensuring that the mat body 1 remains flat and unbent during the exercise. The rear part of the lower limb height limiting frame 2 is fixedly connected to the front part of the anti-bending mat body 1 at an obtuse angle. The front part of the lower limb height limiting frame 2 includes a straight bar body 21, the bottom surface of which is a limiting curve for contact with the exerciser's lower limbs. The height difference between the bottom surface of the limiting curved surface and the bottom surface of the anti-bending pad 1 is not less than 5cm and not more than 15cm. A forward flexion positioning plate 3 is centrally located within the lower limb height limiting frame 2. The forward flexion positioning plate 3 includes several traction anchors 31 arranged evenly in a straight line. Through the arrangement of the lower limb height limiting frame 2 and the forward flexion positioning plate 3, this device can assist the exerciser in pressing down their legs to prevent the lower limbs from lifting upwards during sit-ups, and also assist the exerciser in providing a gripping position for the upper limbs to maintain the flexed state during seated forward flexion. This technical solution has a straightforward structure, no complex transmission mechanisms, is easy to assemble and store, has a low failure rate, and is not easily damaged.
[0017] The above embodiments illustrate three examples of implementing the aforementioned technical solutions. The term "embodiment" as used herein means that a specific feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of this application. The appearance of this phrase in various locations within the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. Where there is no conflict, the various embodiments in this application can be combined with each other.
[0018] Embodiment 1 discloses a dual-purpose mat for sit-ups and lateral forward bends, including an anti-bending mat body 1 and a lower limb height limiting frame 2. The anti-bending mat body 1 has an anti-bending structure to prevent significant bending deformation, ensuring that the anti-bending mat body 1 remains flat and unbent during the exercise. The rear part of the lower limb height limiting frame 2 is fixedly connected to the front part of the anti-bending mat body 1 at an obtuse angle. The front part of the lower limb height limiting frame 2 includes a straight bar body 21, the bottom surface of which is used to connect with the exerciser's lower limbs. The limiting curved surface has a height difference of 5cm between its bottom surface and the bottom surface of the anti-bending pad 1. A forward flexion positioning plate 3 is centrally located within the lower limb height limiting frame 2. The forward flexion positioning plate 3 includes several traction anchors 31 arranged evenly in a straight line. Through the lower limb height limiting frame 2 and the forward flexion positioning plate 3, this device can assist the exerciser in pressing down their legs to prevent the lower limbs from lifting upwards during sit-ups, and also assist the exerciser in providing a gripping position for the upper limbs to maintain the flexion state during seated forward flexion. This technical solution has a straightforward structure, eliminates complex transmission mechanisms, is easy to assemble and store, has a low failure rate, and is not easily damaged.
[0019] The anti-bending pad 1 includes a PVC board with a fabric layer attached to its upper surface. The attachment method can be adhesive. Further optimization is that a sponge pad is provided between the fabric layer and the PVC board, with the main design purpose of providing a flexible cushioning effect, reducing the risk of the exerciser's waist being directly contacted and rubbed by the PVC board when performing sit-ups.
[0020] Example 2 discloses a dual-purpose mat for sit-ups and lateral bending. The difference between this example and Example 1 is that the height difference between the bottom surface of the limiting curved surface and the bottom surface of the anti-bending mat 1 is 15cm. The anti-bending mat 1 includes an elastic pad 11. In this example, the elastic pad 11 can be a sponge pad or a plastic foam pad, designed to achieve a flexible cushioning effect. The elastic pad 11 is equipped with a base frame 12, which is a metal frame structure. In this example, the base frame 12 is a rectangular frame, which can be a rectangle, a rectangle with rounded corners or chamfers, or further designed as an approximately rectangular isosceles trapezoid, a trapezoid with chamfers or rounded corners, etc. The base frame 12 is connected around the outer contour of the elastic pad 11. Several channels for the base frame 12 to pass through can be provided on each outer edge of the elastic pad 11. After the base frame 12 passes through these channels, it forms a relative connection with the elastic pad 11, improving the support capacity of the anti-bending mat 1. When storage is needed, this dual-purpose mat can also be placed upright against a wall. When in use, the base frame 12 and the elastic pad 11 are placed directly on the surface of the training ground. The contact surface with the ground can be equipped with anti-slip mats as needed. The anti-slip mats can be made of rubber or silicone.
[0021] like Figures 1 to 4As shown, Embodiment 3 discloses a dual-purpose mat for sit-ups and lateral bending. The difference between this embodiment and Embodiment 2 is that the anti-bending mat 1 includes a PVC sheet with a fabric layer attached to its upper surface. The bottom of the PVC sheet is provided with mounting threaded holes, and the base frame 12 is correspondingly provided with mounting through holes. The PVC sheet and the base frame 12 are connected by screws to form a single unit. The height difference between the bottom surface of the limiting curved surface and the bottom surface of the anti-bending mat 1 is 12cm. In this embodiment, the base frame 12 is a rigid plastic tubular composite frame, which can be made of polyoxymethylene or nylon to ensure rigidity. This design achieves both weight reduction and increased abrasion resistance. The base frame 12 includes a rear end frame tube and two opposing support rods 121, with a distance of 30cm between them. When the practitioner performs a seated forward bend, the two support rods 121 are positioned within the area projected onto the anti-bending mat 1 by the practitioner's two legs, effectively enhancing the anti-bending capacity and preventing the anti-bending mat 1 from bending and deforming. The front ends of the two support rods 121 are welded to the rear end of the lower limb height limiting frame 2. A frame plate assembly 22 is centrally located at the rear of the lower limb height limiting frame 2, and the assembly can be connected by welding. The device includes two opposing vertical plates with a horizontal axis supporting them. The bottom of the forward bending positioning plate 3 has a positioning groove I 32 that mates with the horizontal axis, and a positioning groove II 33 that mates with the straight bar 21. The positioning groove I 32 includes a wide opening that opens downwards and rearwards, the bottom of which connects to a long groove I extending towards the front. The positioning groove II 33 includes an angled opening that opens downwards and rearwards, the bottom of which connects to a long groove II extending towards the front. The wide and angled openings allow the forward bending positioning plate 3 to be easily installed, preventing vertical movement and allowing only downward and angled installation. The upper part is removed to enhance the user experience; the elongated groove I and elongated groove II are of the same length, and together with the wide-mouthed positioning through groove I 32 and the oblique-mouthed positioning through groove II 33, they can be easily disassembled. After pushing the forward bending positioning plate 3 forward, it can be disassembled without considering the length of the horizontal groove. The same principle applies during assembly; the two vertical plates are set in parallel, and the distance between the two vertical plates is not less than the thickness of the forward bending positioning plate 3 and the difference in size is not greater than 2mm. In this embodiment, 2mm is preferred. At the same time, it is also necessary to ensure that the gap between the forward bending positioning plate 3 and the two vertical plates can be slidably engaged, and it should not be too small to increase the difficulty of disassembly.
[0022] In this embodiment, a traction handle is also included. The traction anchor 31 is a traction groove located on the upper surface of the forward bending positioning plate 3. The traction groove is an oblique groove that opens forward, and multiple oblique grooves are evenly arranged. The traction handle is at least one of a traction stick, a traction belt, or a traction rope. In use, the exerciser holds both ends of the traction handle and places the middle part of the traction handle inside the traction groove. The exerciser can then use the traction handle to achieve a static forward bending posture.
[0023] When performing sit-ups, the exerciser can choose to remove the forward bending positioning plate 3; alternatively, they can sit on the anti-bending mat 1 and place their lower limbs, i.e., their calves or feet, under the limiting curved surface on both sides of the forward bending positioning plate 3, so that the upper surface of the lower limbs contacts the limiting curved surface. During the exercise, under the action of the anti-bending mat 1, the limiting curved surface will provide downward pressure to the exerciser's lower limbs, preventing the exerciser's lower limbs from lifting up during sit-ups. After completing the exercise, the exerciser can simply remove their lower limbs.
[0024] When the practitioner performs a seated forward bend, the forward bend positioning plate 3 and the lower limb height limiting frame 2 are combined to form Figure 1 After reaching the indicated position, sit on the anti-bending mat 1, with the soles of your feet against the rear surface of the straight bar 21. Hold the two ends of the traction handles in parallel with both hands. Here, we take a traction stick as an example. After the middle part of the traction stick is aligned with the appropriate traction groove, the exerciser can maintain a flexed state to achieve flexion and stretching training. After completing the exercise, the exerciser can release the traction handles.
[0025] It is understood that the above description is only for illustrating specific embodiments of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of disclosure of this application.
