Technical Field

[0001] This utility model relates to the field of assistive writing technology, and in particular to an adaptive grip assistive writing device. Background Technology

[0002] Assistive writing devices are tools designed to help specific groups of people write more smoothly. Existing assistive writing devices, such as telescopic pen grips, use Velcro straps to attach to a child's wrist. Through the cooperation of telescopic ribs and a ball in the palm, they can adaptively adjust according to the size of the child's hand, ensuring that each child can find the most suitable pen grip position for themselves. This helps users achieve the correct grip posture and improves the writing experience.

[0003] However, when children wear a retractable pen grip for handwriting, the Velcro straps and retractable shank directly adhere to the child's wrist skin, covering a large area of ​​the skin. This can cause the covered area of ​​the wrist to become stuffy and hot, affecting the child's comfort when using the retractable pen grip and thus impacting the effectiveness of the writing aid. Utility Model Content

[0004] Therefore, it is necessary to provide an adaptive grip assistive writing device to address the problem of stuffiness that easily occurs on the covered wrist skin.

[0006] In one embodiment, the bottom of the keel frame is fixedly connected with equally spaced flexible pads.

[0007] In one embodiment, the end of the keel frame has an observation hole, and the end of the keel plate has equally spaced positioning holes. The observation holes and positioning holes work together to improve ventilation at the point of contact between the keel frame and the child's wrist skin, ensuring the child's comfort while wearing the writing aid.

[0008] In one embodiment, a positioning rod is slidably connected to the inner wall of the keel frame, and the surface of the positioning rod is engaged with the inner wall of one of the positioning holes.

[0009] In one embodiment, a second magnetic ring is fixedly connected to the inner wall of the keel frame, and the surface of the positioning rod is slidably connected to the inner wall of the second magnetic ring.

[0010] In one embodiment, a first magnetic ring is fixedly connected to the surface of the positioning rod, and the first and second magnetic rings attract each other with opposite poles. Through the cooperation of the positioning rod, the first magnetic ring, and the second magnetic ring, the keel plate is locked after its position is adjusted within the keel frame, ensuring that the adjusted palm ball is stably positioned within the child's palm.

[0011] In one embodiment, the inner wall of the through hole is recessed in a funnel shape.

[0012] In one embodiment, a sliding hole is provided on the inner wall of the keel frame, and the lower end of the surface of the positioning rod is slidably connected to the inner wall of the sliding hole. The sliding hole is used to limit the upward movement of the positioning rod, preventing the positioning rod from completely disengaging from the keel frame, thereby avoiding the risk of the positioning rod being lost.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes an adaptive grip assistive writing device.

[0019] In one embodiment, an adaptive grip assistive writing device includes: a frame 100, a slidably connected keel plate 200 to the inner wall of the frame 100, a palm ball 300 fixedly connected to one side of the keel plate 200, two straps 400 fixedly connected to the front end of the frame 100, and a textured Velcro 500 and a hook Velcro 600 fixedly connected to the surface of the straps 400; an anti-suffocation mechanism 700, including a hollow sleeve 704 fixedly connected to the surface of the palm ball 300, a through hole 705 on the inner wall of the palm ball 300, rows of equally spaced holes 701 at the ends of the frame 100 and the keel plate 200, and rows of equally spaced strip holes 702 at the ends of the straps 400, the textured Velcro 500 and the hook Velcro 600, and the inner wall of the through hole 705 being recessed in a funnel shape.

[0020] It should be noted that the fifth-generation telescopic pen grip is usually composed of a keel frame 100, a keel plate 200, a palm ball 300, a strap 400, a textured Velcro 500, and a hook Velcro 600. The brand of the fifth-generation telescopic pen grip is Youwang, and the product number is 10094521121507.

[0021] The keel frame 100, keel plate 200, palm ball 300, and hollow sleeve 704 are all made of pacifier-grade soft silicone, making the keel frame 100, keel plate 200, palm ball 300, and hollow sleeve 704 comfortable, environmentally friendly, and non-irritating to the hand. They make it comfortable for children to hold the pen, and children are less resistant and more likely to persist.

[0022] In this embodiment, when a child needs to use the assistive writing device, the bottom of the keel frame 100 is placed against the child's wrist skin, and the two straps 400 are successively placed against the child's wrist skin and passed through the pre-drilled holes on the keel frame 100. The hook-and-loop fastener 500 is then attached to the hook-and-loop fastener 600, thereby stably binding the keel frame 100 to the child's wrist. The keel frame 100 provides stable support for the palm ball 300, preventing it from wobbling. By binding the keel frame 100 to the child's wrist skin and placing the palm ball 300 against the child's palm, the child's ring finger and little finger are positioned to effectively control the grip on the pen. The palm ball 300 applies linear force to prevent wrist hooking and fist clenching, allowing the child to hold the writing pen correctly and avoid wrist hooking during writing.

[0023] Air is ventilated through the perforated sleeve 704 and the through hole 705 to the child's palm limit area, preventing stuffiness and discomfort in the palm area when the child wears the assistive writing device. Air is ventilated through the exhaust hole 701 and the strip hole 702 to the child's wrist skin limit area, preventing stuffiness and discomfort in the wrist area when the child wears the assistive writing device, thus improving the child's comfort when writing with the assistive writing device.

[0024] like Figure 3 As shown, the bottom of the keel frame 100 is fixedly connected with equally arranged flexible pads 703, the end of the keel frame 100 is provided with observation holes 706, and the end of the keel plate 200 is provided with equally arranged positioning holes 707.

[0025] In this embodiment, the flexible pad 703 is used to prevent the keel frame 100 from directly contacting the child's wrist skin, so that there is a gap between the bottom of the keel frame 100 and the child's wrist skin, which facilitates the flow of air between the bottom of the keel frame 100 and the child's wrist skin. The air is blown to the child's wrist skin contact area through the observation hole 706 and multiple positioning holes 707, avoiding stuffiness at the child's wrist skin contact area.

[0026] like Figure 5As shown, a positioning rod 708 is slidably connected to the inner wall of the keel frame 100. The surface of the positioning rod 708 is engaged with the inner wall of one of the positioning holes 707. A second magnetic ring 710 is fixedly connected to the inner wall of the keel frame 100. The surface of the positioning rod 708 is slidably connected to the inner wall of the second magnetic ring 710. A first magnetic ring 709 is fixedly connected to the surface of the positioning rod 708. The first magnetic ring 709 and the second magnetic ring 710 attract each other with opposite poles. A sliding hole 711 is opened in the inner wall of the keel frame 100. The lower end of the surface of the positioning rod 708 is slidably connected to the inner wall of the sliding hole 711.

[0027] In this embodiment, when it is necessary to adjust the contact distance between the palm ball 300 and the child's palm, the positioning rod 708 is pulled up on the inner wall of the keel frame 100 away from the corresponding positioning hole 707, so that the first magnetic ring 709 moves away from the second magnetic ring 710, releasing the locking of the keel plate 200 in the keel frame 100. The keel plate 200 is then pulled to move laterally to a suitable position in the keel frame 100, so that the hollow sleeve 704 on the surface of the palm ball 300 contacts the child's palm. The positioning rod 708 is pushed down in the keel frame 100 and slides into the corresponding positioning hole 707, so that the first magnetic ring 709 is magnetically attracted to the second magnetic ring 710, locking the keel plate 200 in the keel frame 100. This allows the palm ball 300 and the hollow sleeve 704 to adaptively contact the palms of children of different sizes.

[0028] Working principle: The flexible pad 703 is used to prevent the keel frame 100 from directly contacting the child's wrist skin, so that there is a gap between the bottom of the keel frame 100 and the child's wrist skin, which allows air to flow between the bottom of the keel frame 100 and the child's wrist skin. The air is blown to the child's wrist skin contact area through the observation hole 706, multiple positioning holes 707, exhaust hole 701 and strip hole 702, so as to avoid stuffiness at the child's wrist skin contact area. The air is also used to ventilate the child's palm limit area through the hollow sleeve 704 and the through hole 705, so as to avoid stuffiness and discomfort in the palm of the child when wearing the auxiliary writing device.

[0029] It should be noted that the keel frame 100, keel plate 200, palm ball 300, strap 400, hook and loop fastener 500, hook and loop fastener 600, first magnetic ring 709, and second magnetic ring 710 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
