Description

Technical Field

[0001] This utility model relates to the field of learning tools, and in particular to a posture corrector with a chin rest. Background Technology

[0002] Posture correctors are widely used as tools to help students maintain correct sitting posture. They are clipped to the desk and placed in front of the student's chest when writing or reading, limiting forward leaning and effectively preventing problems such as scoliosis and myopia caused by poor sitting posture.

[0003] In existing technologies, such as the posture corrector described in patent CN202321444807, only a chest support (posture correction and limiting component) is included. During use, the chest support is adjusted to a position in front of the user's chest to prevent forward leaning and, to some extent, assist the user in maintaining an upright posture. However, existing technologies lack a support for the user's chin, failing to effectively restrain improper sitting postures such as head tilting or forward head movement. Furthermore, prolonged desk work easily leads to neck pain and cervical spine pain, and existing technologies cannot provide support for the head or alleviate the load on the cervical spine. Utility Model Content

Detailed Implementation

[0026] The following detailed description of a posture corrector with a chin support according to the present invention is provided in conjunction with specific embodiments.

[0027] A posture corrector with a chin support includes a fixation part and a body. The body includes a chest support bracket 3, a chin support bracket 5, and a support part 2 connected to the fixation part. The chest support bracket 3 is slidably installed in the support part 2, and the chin support bracket 5 is slidably installed in the chest support bracket 3. The chest support bracket 3 is provided with a chest support assembly, and the chin support bracket 5 is provided with a chin support assembly. The support part 2 is provided with a first locking device that cooperates with the chest support bracket 3, and the chest support bracket 3 is provided with a second locking device that cooperates with the chin support bracket 5.

[0028] The fixing part of the orthosis is a tabletop 30 or a clamping device 1. In this solution, if... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the fixing part of the orthodontic device is a clamping device 1, used to clamp onto the table to fix the posture corrector with a chin support. The chest support bracket 3 is slidably installed in the support part 2, and the chin support bracket 5 slides in the vertical channel 4 of the chest support bracket 3, and the height is locked by the corresponding locking structure. In use, by pressing the first locking device, the chest support bracket 3 is pulled out from the support part 2 and raised to the position in front of the user's chest, and the chin support bracket 5 is raised at the same time. Then, by pressing the second locking device, the chin support bracket 5 is pulled out from the chest support bracket 3 and raised to the position below the user's chin. The top of the chin support bracket is equipped with a chin support component, which can be a rigid plastic structure or a flexible material structure, such as a silicone pad. This posture corrector incorporates a chin support, which not only prevents the user from leaning forward but also prevents and corrects improper postures such as head tilting and forward head movement. It also supports the head, helping to distribute the load on the cervical spine. On one hand, when not in use, the chin support can be hidden within the chest support 3, allowing for phased posture correction. In the first phase, both the chest support 3 and the chin support 5 can be used. In the second phase, once the child has developed good posture and no longer tilts their head or forwards their neck, the chin support can be hidden away. On the other hand, the chest support 3 and the chin support 5 can be stored within a single support unit 2, resulting in a neat structure, reduced overall size, and relatively convenient operation.

[0029] like Figure 5 , Figure 6 As shown, the breast support assembly includes a first tray 18, a first cover plate 19, a first pad 31, and a first soft pad 20. The first tray 18 is fixed to the outer side of the top of the breast support bracket 3, the first cover plate 19 is fixed inside the first tray 18, and the first soft pad 20 is mounted on the first cover plate 19 via the first pad 31.

[0030] The first tray 18 is integrally connected to the outer side of the top of the chest support bracket 3. The first cover plate 19 is inserted into the insertion hole on the first tray 18 through a connecting post. The edge of the first soft pad 20 is provided with a flange, and the flange has a mounting hole. The first soft pad 20 is fitted onto the first pad plate 31 through the flange, and the mounting hole fits onto the connecting post on the edge of the first pad plate 31. The first pad plate 31 is inserted into the insertion hole on the first cover plate 19 through the connecting post, or it is installed on the first cover plate 19 by screws or adhesive.

[0031] like Figure 5 , Figure 6 As shown, the chin support assembly includes a second tray 21, a second pad 22, and a second cushion 23. The second tray 21 is fixed to the top of the chin support bracket 5, and the second cushion 23 is installed inside the second tray 21 through the second pad 22.

[0032] The second pad 23 has a flange on its inner side with mounting holes. The second pad 23 is fitted onto the second pad 22, and the mounting holes fit onto the connecting posts on the edge of the second pad 22. The second pad 22 is inserted into the insertion holes of the second tray 21 through the connecting posts.

[0033] like Figure 5 As shown, the first locking device includes a first keyway 6 and a first button located on the support part 2. The first button includes a first pressing part 7 and a first latching part 8. One end of the first keyway 6 is provided with a first latching hole 10 corresponding to the first latching part 8, and the other end is provided with a first elastic member 9 between it and the first pressing part 7. The middle section of the first button is rotatably installed in the first keyway 6. The chest support bracket 3 is vertically provided with a first latching tooth plate 11 that cooperates with the first latching part 8.

[0034] Specifically, the first button has a connecting ear on its inner side, and the first key slot 6 has a through hole on its side. A connecting pin is inserted into the through hole and passes through the connecting ear to install the first button in the first key slot 6. One end of the first key slot 6 has a first latching part 8, and the other end is fitted with a first elastic element 9 between it and the first key slot 6. The side wall of the support part 2 has a first latching hole 10 corresponding to the position of the first latching part 8. The breast support bracket 3 has a first locking tooth plate 11 vertically arranged to cooperate with the first latching part 8. In the initial state, the first elastic element 9 supports the first pressing part 7 under the action of elastic force, and the first latching part 8 at the upper end of the first button moves towards the first locking tooth plate 11, thereby engaging the first latching part 8 with the first locking tooth plate 11 and limiting the breast support bracket 3 within the support part 2. Conversely, by pressing the first pressing part 7, the upper end of the first button is lifted, thereby disengaging the first latching part 8 from the first locking tooth plate 11, and the breast support bracket 3 can be pulled out from the support part 2. After adjusting the height, the first button can be released.

[0035] like Figure 6 As shown, the second locking device includes a second keyway 12 and a second button located on the chest support bracket 3. The second button includes a second pressing part 13 and a second latching part 14. One end of the second keyway 12 is provided with a second latching hole 16 corresponding to the second latching part 14, and the other end is provided with a second elastic member 15 between the second pressing part 13. The chin support bracket 5 is vertically provided with a second locking tooth disc 17 that cooperates with the second latching part 14.

[0036] In the initial state, the second elastic element 15, under the action of elastic force, supports the second pressing part 13, and the second buckle part 14 moves towards and engages with the second locking plate 17, thereby limiting the chin support bracket 5 within the chest support bracket 3. Conversely, by pressing the second pressing part 13, the upper end of the second button is lifted, thereby disengaging the second buckle 14 from the second locking plate 17, allowing the chin support bracket 5 to be pulled out from the chest support bracket 3. After adjusting the height, the second button can be released.

[0037] In this design, when the chest support bracket 3 is raised, the second locking device is located on the chest support bracket 3, so the second locking device is still in a state of limiting the chin support bracket 5, and the chin support bracket 5 will not easily come out.

[0038] like Figure 1 , Figure 2 As shown, the clamping device 1 includes a first clamping plate 24 and a second clamping plate 25. The bottom of the first clamping plate 24 is provided with a screw 26, and the second clamping plate 25 is provided with a mounting hole through which the screw 26 can pass. The screw 26 is threadedly connected to the bottom of the second clamping plate 25 with an adjusting nut 27.

[0039] In use, the first clamp 24 and the second clamp 25 are placed on the top and bottom of the table respectively, and the first clamp 24 and the second clamp 25 are tightened by adjusting the nut 27.

[0040] In other embodiments, such as Figure 9 As shown, the fixing part of the orthodontic device is a tabletop 30. The tabletop 30 can be placed directly on the desktop without clamping the desktop, which is suitable for situations where it is inconvenient to clamp, such as when there is a drawer and the edge of the table cannot be clamped.

[0041] like Figure 7 , Figure 8 As shown, the bottom inner side of the support part 2 is provided with a buckle hole 29, and the clamping opening of the first clamping plate 24 away from the clamping side is provided with an elastic buckle 28. The bottom of the support part 2 is rotatably installed in the clamping opening of the first clamping plate 24 away from the clamping side via a pivot. The elastic buckle 28 is engaged in the buckle hole 29 to fix the angle. After use, the support part 2 can be rotated to release the elastic buckle 28 from the buckle hole 29. The support part 2 is rotatably connected to the clamping device 1, which is convenient for storage. The clamping device 1 can have various forms, as long as it can clamp the tabletop, such as the clamping devices shown in 202421283390.3, 202121815592.4, and 202121497049.4.
