Abstract
Description
Technical Field
[0001] This utility model relates to the field of orthotics, and in particular to an arm-type posture corrector. Background Technology
[0002] Writing is a frequent activity for students, but due to the lack of strict guidance and management, many writers maintain improper postures, such as tilting their heads, leaning to one side, bending their arms at inconsistent angles, or hunching over the table. These postures can lead to problems like nearsightedness, hunchback, and cervical spine deformities. To correct these postures, various writing posture correctors have emerged, addressing issues like upper body posture, head movement, and right wrist grip. Many writing tools have also been developed, influencing pen grip and writing posture through improvements. However, these tools can lead to dependency, only correcting specific areas and offering limited effectiveness in correcting overall posture. Furthermore, their complex structures make them inconvenient to carry and store, causing additional burden and discomfort, impacting both writing efficiency and the effectiveness of the correction.
[0003] Therefore, there is a need to design a posture corrector that is not only simple in structure, easy to carry and store, but also has a better corrective effect. Utility Model Content
[0004] In order to solve the technical problems of existing technologies such as complex structure, inconvenience in carrying and storing, and the need to improve posture correction and achieve more standardized results, this utility model provides an arm-type posture corrector.
[0005] To achieve the objectives of this utility model, the technical solution adopted is as follows:
[0006] An arm-type posture corrector includes a posture corrector box and a strap assembly. The posture corrector box includes a lid and a bottom, and one side of the lid and one side of the bottom are rotatably connected by a rotating structure.
[0007] The box lid is composed of a first inclined surface, a first flat surface, and a first curved surface connected in sequence, while the box bottom is composed of a second inclined surface, a second flat surface, and a second curved surface connected in sequence.
[0008] The rotating structure includes a thin shaft and a thick shaft. The thin shaft is coaxially arranged in a cylindrical hollow cavity opened in the thick shaft. The thin shaft is integrally connected to the first inclined surface of the lid. The thick shaft is integrally connected to the second inclined surface of the bottom of the box. The two ends of the thin shaft are longer than the two ends of the thick shaft. The thin shaft and the thick shaft can rotate relative to each other, driving the lid and the bottom of the box to rotate relative to each other.
[0009] The first inclined plane has an inclination angle of α°; the second inclined plane of the bottom of the box has an inclination angle of β°, 90°≤α+β<95°; the maximum opening angle of the lid and bottom of the box is 360°-(α+β);
[0010] The strap assembly includes a first strap and a second strap, with the first strap fixed inside the box lid and the second strap fixed inside the box bottom.
[0011] Furthermore, a first arc-shaped notch is provided at the first arc surface; a second arc-shaped notch is provided at the second arc surface.
[0012] Furthermore, the first strap is directly fixed to the inner bottom surface of the box lid, and the first strap is a ring structure without free ends or a strip structure with two free ends; the second strap is directly fixed to the inner bottom surface of the box bottom, and the second strap is a ring structure without free ends or a strip structure with two free ends.
[0013] Furthermore, the first strap has matching hook and loop fasteners at both ends; the second strap has matching hook and loop fasteners at both ends.
[0014] Furthermore, it also includes a buckle assembly, which includes a sub-buckle and a female buckle. One end of the sub-buckle is fixed to the first plane of the box cover, and one end of the female buckle is fixed to the second plane of the box bottom. The free ends of the sub-buckle and the female buckle are fastened together.
[0015] Furthermore, the first strap is housed in a first receiving cavity inside the box lid, and the second strap is housed in a second receiving cavity inside the box bottom.
[0016] Furthermore, a locking structure is provided on the contact surface after the lid and bottom of the box are fastened together.
[0017] Furthermore, the locking structure is a snap-fit structure, which includes multiple sets of sub-snap-fit parts disposed on the edge of the lid; and a female snap-fit part disposed on the edge of the bottom of the box; when the lid and the bottom of the box are fastened together, the sub-snap-fit parts and the female snap-fit parts are matched and engaged.
[0018] Furthermore, each sub-clamping part includes two grooves and a protrusion between the grooves; each female clamping part includes two protrusions corresponding to the sub-clamping part and a groove between the protrusions, and the grooves and protrusions between the lid and the bottom of the box are interlocked and fixed.
[0019] Furthermore, the locking structure on the contact surface between the lid and the bottom of the box adopts a magnetic structure.
[0020] Compared with the prior art, the beneficial effects of this utility model are specifically reflected in:
[0021] 1. This utility model provides a first inclined surface and a second inclined surface on the lid and bottom of the box, respectively. The first inclined surface has an inclination angle of α°, and the second inclined surface on the bottom has an inclination angle of β°. When the lid and bottom are opened to their maximum angle, the angle is limited by the inclination angles of the first and second inclined surfaces: 90°≤α+β<95°. The maximum opening angle of the lid and bottom is 360°-(α+β), which allows the angle between the upper and lower arm to be controlled within a reasonable range of α+β (not less than 90 degrees) during writing. This standardizes the arm's extension angle, and to make other parts of the body more comfortable, the wearer will automatically adjust the posture of other parts of the body, thus promoting the standardization of the wearer's writing posture.
[0022] 2. This utility model features corresponding arc-shaped notches on the lid and bottom of the box. When worn, the lid and bottom contact the wearer's arm. The arc-shaped notches are designed to reduce friction caused by contact with the arm, thereby reducing discomfort for the wearer. The angle of the arc is as large as possible, and the material of the arc edge structure is made of soft material to reduce discomfort when wearing it close to the arm.
[0023] 3. This utility model provides corresponding receiving cavities in the box lid and box bottom, which can store the strap assembly in the receiving cavities, achieving convenient storage and small space occupation; in addition, the strap can be a one-piece circular structure without free ends or a strip structure with free ends, providing a variety of strap options and lower usage costs.
[0024] 4. When the lid and bottom of this utility model are opened to their maximum angle, the angle between the back of the lid and bottom is 90°≤α+β<95°, which can standardize the arm's extension angle and promote the standardization of the wearer's writing posture. At the same time, the front of the lid and bottom can rotate, allowing the arm to be straightened to perform other actions besides writing when wearing the device, without having to remove the posture corrector, making it more convenient to use.
[0025] 5. The inventor has verified that this utility model can achieve the posture correction effect when worn on either arm. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below. Technical features in various embodiments of this utility model can be combined appropriately without conflict.
[0040] In the description of this utility model, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected, i.e., there is an intermediate element. Conversely, when an element is said to be "directly" connected to another element, there is no intermediate element.
[0041] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.
[0042] Example 1
[0043] Combination Figure 1-4 As shown, this utility model provides an arm-type posture corrector, including a posture corrector box and a strap assembly. The posture corrector box includes a box cover 1 and a box bottom 2. One side of the box cover 1 and one side of the box bottom 2 are rotatably connected by a rotating structure.
[0044] The lid 1 is composed of a first inclined surface 11, a first flat surface 12, and a first arc surface 13 connected sequentially from back to front. In this embodiment, the connection between the lid 1 and the bottom 2 is considered the rear, and the opening / closing point of the lid 1 and the bottom 2 is considered the front.
[0045] The connection between the first inclined surface 11 and the first plane 12 is set with a rounded corner structure.
[0046] A first arc-shaped notch 14 is provided at the first arc surface 13.
[0047] The bottom 2 of the box has a shape that is basically the same as that of the lid 1. The bottom 2 is composed of a second inclined surface 21, a second flat surface 22 and a second arc surface 23 connected in sequence from back to front. The connection between the second inclined surface 21 and the second flat surface 22 is set with a rounded corner structure. A second arc-shaped notch 24 is provided at the second arc surface 23.
[0048] In a specific example
[0049] The rotating structure includes a thin shaft 4 and a thick shaft 5. The thin shaft 4 is coaxially arranged in the cylindrical hollow cavity of the thick shaft 5. The thin shaft 4 is integrally connected between the left and right sides of the rear end of the box cover 1 as the first rotating part. More specifically, the thin shaft 4 is connected between the left and right sides of the rear end of the first inclined surface 11.
[0050] Correspondingly, a thick shaft 5 is provided between the left and right sides of the rearmost end of the box bottom 2, serving as a second rotating part; the thick shaft 5 is a hollow shaft, and a thin shaft 4 is coaxially disposed within the cylindrical hollow cavity of the thick shaft 5; the two ends of the thin shaft 4 are longer than the two ends of the thick shaft 5. Thus, the thin shaft 4 of the box cover 1 can rotate around the thick shaft 5 within the thick shaft 5, or the thick shaft 5 of the box bottom 2 can rotate around the thin shaft 4, allowing the posture correction box to open or close.
[0051] In a specific example, a thick shaft 5 can be set between the left and right sides of the rear end of the lid 1, and a thin shaft 4 can be set between the left and right sides of the rear end of the bottom 2.
[0052] The first inclined surface 11 of the lid 1 has an inclination angle of α°; the second inclined surface 21 of the bottom 2 has an inclination angle of β°, and 90°≤α+β<95°. The inventors discovered through research that when maintaining a correct writing posture, the arm is always bent at a 90-degree angle. Once this angle is changed, especially when it is less than 90 degrees, the upper body will inevitably be in a hunched position, and the eyes will be too close to the table, resulting in an incorrect writing posture. An angle slightly greater than 90 degrees has little impact on the correct writing posture. When the angle is much greater than 90 degrees (e.g., with the arm straight), because the eyes are too far from the table, people will naturally feel uncomfortable writing and will not adopt this posture.
[0053] Meanwhile, the front of the lid 1 and the bottom 2 can rotate, making it convenient to straighten the arm to do other actions besides writing while wearing the device, without having to remove it.
[0054] The lid 1 and the bottom 2 of the box rotate relative to each other to open. When the box is opened to its maximum extent, the angle between the back sides of the lid 1 and the bottom 2 in the opening direction is equal to (α+β). The front side is used to fit the inside of the elbow.
[0055] The strap assembly includes a first strap 6 and a second strap 7, which are strip-shaped structures; the first strap 6 is housed in a first receiving cavity 8 inside the box lid 1, and the second strap 7 is housed in a second receiving cavity 9 inside the box bottom 2.
[0056] The middle part of the first strap 6 is fixed to the bottom surface of the first receiving cavity 8 inside the box cover 1; the two ends of the first strap 6 are free ends, and the two ends of the first strap 6 are respectively provided with matching hook and loop fasteners.
[0057] The middle part of the second strap 7 is fixed to the bottom surface of the second receiving cavity 9 inside the box bottom 2. The two ends of the second strap 7 are free ends, and each end of the second strap 7 is provided with a matching hook and loop fastener.
[0058] In a specific example
[0059] The two free ends of the first strap 6 and the second strap 7 can also be connected using Velcro or other methods.
[0060] In one specific embodiment
[0061] The first binding strap 6 and the second binding strap 7 can also be made without two free ends, and can directly adopt a ring structure.
[0062] Working principle:
[0063] When in use, rotate the lid 1 and the bottom 2 of the box relative to each other to open them;
[0064] Place the receiving cavity of the box lid 1 and the box bottom 2 against the inside of the right elbow joint;
[0065] Then, after wrapping the first strap 6 and the second strap 7 around the upper arm and forearm of the right elbow joint respectively, secure them with Velcro. Figure 7 As shown, this allows the posture correction box to be fixed at the right elbow joint;
[0066] When the right arm is writing, the upper arm and forearm press against the lid 1 and the bottom 2 of the box. The angle (α+β) between the back of the lid 1 and the bottom 2 in the opening direction restricts the right elbow joint to maintain 90°.
[0067] To ensure a more comfortable writing posture for other parts of the body, the wearer will actively adjust their overall writing posture, promoting standardization of their writing technique. When the writer adopts the correct writing posture, wearing this device on the corresponding position of the left or right arm ensures that the bending angle α of the left and right arm is exactly 90 degrees, making writing not only comfortable but also more standardized.
[0068] The first arc-shaped notch 14 contacts the lower arm, and the second arc-shaped notch 24 contacts the upper arm. In order to reduce the friction between the arc-shaped structures and the arm, thereby reducing discomfort for the wearer, the angle of the arc is as large as possible, and the material used for attaching the arc-shaped notch is a soft material to reduce discomfort when wearing it on the arm.
[0069] Example 2
[0070] Combination Figure 3 , 4 As shown, unlike Embodiment 1, this embodiment also includes a buckle assembly, which includes a sub-buckle 101 and a female buckle 102. One end of the sub-buckle 101 is fixed to the first plane 12 of the box cover 1, and one end of the female buckle 102 is fixed to the second plane 22 of the box bottom 2. The free ends of the sub-buckle 101 and the female buckle 102 are connected by fasteners, Velcro, or magnetic attraction.
[0071] When finished using the product, store the first strap 6 and the second strap 7 in their respective accommodating cavities, and fasten the male buckle 101 and the female buckle 102 to facilitate the storage of the first strap 63 and the second strap 74.
[0072] Example 3
[0073] like Figure 5 As shown, unlike Embodiment 1 or Embodiment 2, in this embodiment, a locking structure is also provided on the contact surface after the lid 1 and the bottom 2 are fastened together, so that the lid 1 and the bottom 2 can be interlocked after they are fastened together.
[0074] In a specific example
[0075] The locking structure between the lid 1 and the bottom 2 is a snap-fit structure. The snap-fit structure includes multiple sets of sub-engaging parts 111 disposed on the edge of the lid 1. Each sub-engaging part 111 includes two grooves and a protrusion between the grooves.
[0076] And a female latching portion 112 is provided on the edge of the bottom 2 of the box, each female latching portion 112 including two protrusions corresponding to the daughter latching portion 111 and a groove between the protrusions;
[0077] When the lid 1 and the bottom 2 of the box are fastened together, the female locking part 111 and the female locking part 112 engage and match.
[0078] Example 4
[0079] like Figure 6 As shown, unlike embodiment 3, in this embodiment, the locking structure provided on the contact surface between the lid 1 and the bottom 2 is a magnetic structure. The magnetic structure includes multiple sets of thin sheet-shaped magnets 12 that cooperate and attract each other on the edges of the lid 1 and the bottom 2.
[0080] When the lid 1 and the bottom 2 of the box are fastened together, multiple sets of magnetic pieces 12 on the edges of the lid 1 and the bottom 2 of the box cooperate to attract each other.
[0081] The above are merely embodiments of this utility model, described in a relatively specific and detailed manner, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
