Abstract
Description
[Technical Field]
[0001] This invention relates to a rain cover that is attached to the rear child seat of a bicycle, and is a structure that not only provides protection from the rain in rainy weather, but also blocks sunlight and provides ventilation, allowing young children to ride safely and comfortably. [Background technology]
[0002] Conventionally, a rain cover has been attached to the rear child seat of a bicycle to protect it from the effects of rain when it rains.
[0003] Additionally, due to recent climate change, rain covers are also being required to protect against direct sunlight on sunny days.
[0004] However, conventional rain covers have a high airtightness, which makes the inside hot and humid, posing a high risk to the health of young children, including heatstroke.
[0005] Conventional technologies include creating a space between the sheet and cover or creating ventilation holes, but it is difficult to ensure sufficient light blocking, breathability, and safety at the same time. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Utility Model Registration No. 3243124
[0007] [Patent Document 2] Patent No. 5805028 Summary of the Invention [Problem to be solved by the invention]
[0008] Conventional rain covers have insufficient sun protection, making it easy for the interior temperature to rise sharply, especially in the summer. Furthermore, the roof fabric can loosen and come into contact with a child's head or face, potentially causing burns or other injuries.
[0009] Furthermore, due to the high level of airtightness, ventilation was insufficient, which increased the risk of heatstroke when the vehicle was stopped or in hot and humid environments. [Means for solving the problem]
[0010] The roof of the rain cover is made of a material that is water-repellent, insulating, cushioning, and vapor-depositable. In addition, a lightweight core and wire are used to prevent loosening and sagging, improving shape retention.
[0011] To ensure efficient air circulation inside the rain cover, multiple ventilation holes are provided on the sides and back. The ventilation holes have a mesh structure.
[0012] A foldable support part is installed in the ventilation opening, making it possible to fix the ventilation opening cover and ensure a certain level of breathability. [Effects of the Invention]
[0013] The roof of the rain cover blocks sunlight and releases moisture, preventing high temperatures and humidity inside the rain cover. Because the roof is rigid enough to prevent loosening or sagging, the roof, which becomes hot due to direct sunlight, does not come into contact with children inside, preventing injury.
[0014] The installation of multiple ventilation holes promotes air circulation inside the rain cover while driving and when stopped, expelling hot, humid air and reducing the risk of heatstroke. [Brief explanation of the drawings]
[0015] [Figure 1] FIG. 1 is an overall view of the present invention. [Figure 2] FIG. 1 is an overall view of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0016] The embodiment described in this specification is an example of an embodiment of the rain cover, and the embodiment is not limited to the contents of this specification.
[0017] The rain cover is compatible with bicycles with rear child seats that have adjustable headrests or strap holes.
[0018] The rain cover is installed to cover the entire rear child seat, but by leaving the fastener at the connection part 24 of the side part A2 open when installing it, it becomes easy to operate the two belts 42 provided on the inside of the back part 4 of the rain cover.
[0019] Two belts 42 provided on the left and right sides inside the back part 4 of the rain cover are wrapped around the left and right sides of the headrest of the rear child seat. The position of the rain cover is stabilized by wrapping the two belts 42 so that the center between them overlaps with the center line of the rear child seat.
[0020] The buckle of the belt 14 for fastening to the bicycle, located on the inside of the lower part of the front part 1 of the rain cover, is removed, and the belt part is attached to the bicycle frame under the bicycle saddle or in front of the crotch part of the child seat.
[0021] After connecting the buckle attached to the belt 14 with the buckle on the rain cover body, the belt 14 is tightened so that there is no slack, and the rain cover is fixed.
[0022] The belt 14 is wound around the grip bar of the child seat and fastened to secure it.
[0023] After fastening the fastener at the connecting portion 24 of the side portion A2, pull the draw cord 43 provided at the bottom of the rain cover back portion 4 to adjust the slack of the rain cover hem. The draw cord 43 may stretch, so in that case it is advisable to tie it in place to prevent it from getting caught in the rear tire of the bicycle.
[0024] If the temperature or humidity inside the rain cover rises while a child is seated in a rear child seat, the fastener 13 connecting the front section 1 and the front window section 11 is opened, the opened front window section 11 is folded back against the roof section 12, and the tape attached to the tip of the folded front window section 11 is used to attach it to the back section, opening the front of the child seated in the child seat. This allows air to circulate, preventing the temperature and humidity from rising. In addition, the roof section 12 remains open and functions as a sunshade.
[0025] The roof section 12 and the front window section 11 are put together, the fasteners 13 that connect them to the front section 1 are opened, the opened roof section 12 and the front window section 11 are folded back against the back section, and the leading edge of the folded back front window section 11 is glued to the back section, opening up a wide area from in front of and above the child seated in the child car seat. This further promotes air circulation and prevents increases in temperature and humidity.
[0026] The structure used for the roof section 12 requires a three-layer structure similar to that of a thermos. For example, polyester fabric is used for the outermost part, with the surface being water-repellent and the backside being PU coated to ensure sufficient water repellency. A urethane foam sheet is used in the middle section to ensure rigidity and elasticity so that the polyester fabric does not sag. Aluminum vapor deposition fabric is used for the innermost part to ensure the ability to absorb and expel humidity inside the rain cover.
[0027] The side portion A2 of the rain cover is connected to the front portion 1 with a zipper 24 so that it can be opened widely, and opening it completely makes it easier for parents to support their child when getting in and out of the car.
[0028] The rain cover has ventilation holes on the side portions A2, B3, and back portion 4. Side portion A has upper side portion A ventilation hole 22 and lower side portion A ventilation hole 23 on side portion A2, upper side portion B ventilation hole 32 and lower side portion B ventilation hole 33 on side portion B2, and back portion 4 has rear ventilation hole 41. By combining this with opening the connection portion 13 of the front window portion 11, it is possible to provide sun protection on sunny days while ensuring ventilation.
[0029] The upper side A ventilation opening 22, the lower side ventilation opening 23, the upper side B ventilation opening 32, the lower side B ventilation opening, and the rear ventilation opening 41 are made of mesh fabric for ventilation, ensuring good ventilation. Each ventilation opening is fitted with a cover to prevent rainwater from entering. To ensure ventilation while preventing rainwater from entering, the cover is not shaped to completely cover the ventilation structure, ensuring good ventilation. To further ensure ventilation, the ventilation openings are fitted with a folded and stored support member 501 that pushes the cover up even further. Extending the support member and fixing the cover so that it opens more perpendicular to the rain cover further ensures good ventilation of the ventilation opening.
[0030] The rain cover can be stored by opening and folding the adhesive portion of the front window portion 11, and folding the side portion A2, the side portion B3 and the back portion 4.
[0031] The rain cover is provided with a reflector 44 on the back part 4 to ensure safety when riding the bicycle at night. [Explanation of symbols]
