Description

Technical Field

[0001] The present invention relates to a child carrier, and in particular to a head protection device sleeved on the shoulder straps of the child carrier and the child carrier. Background Art

[0002] Parents with children often use strollers, baby carriers, and safety seats to ease the burden on their children when traveling. These infant carriers are also comfortable and safe, making them increasingly popular. For safety reasons, existing infant carriers often feature shoulder and waist straps to secure infants. The length of the shoulder straps is typically adjustable, often using buckles. To enhance comfort and safety, the shoulder straps are also fitted with protective plates for the buckles to protect the infant's head and neck.

[0003] However, most existing guards are only mounted on the shoulder straps. During riding or when the shoulder strap length is adjusted, the guards may move relative to each other and become misplaced, causing the buckles to be exposed outside the guards, or causing the shoulder straps to directly contact the infant's head and neck, thereby reducing comfort and even causing injuries to the infant's head and neck due to collision or friction with the buckles or shoulder straps, thus failing to provide adequate protection.

[0049] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0050] See also Figures 1 to 3The present invention provides a head protection device 100 that is adapted to be mounted on the outside of the shoulder straps 300 and the adjustment buckles 400 connected to the shoulder straps 300 of a child carrier 200, and prevents relative sliding between the adjustment buckles 400 and the shoulder straps 300 connected to the adjustment buckles 400. In the present application, the child carrier 200 of the present invention includes, but is not limited to, strollers, infant carriers, baby sleepers, safety seats, and infant chairs. Specifically, the child carrier 200 of the present invention includes a seat 500 and a backrest 600 connected to the seat 500. Two shoulder straps 300 are symmetrically connected between the seat 500 and the backrest 600. To accommodate children of different ages and body shapes, the shoulder straps 300 are adjustable in length. The adjustment buckles 400 are used to adjust the length of the shoulder straps 300, thereby adaptively securing the child in the child carrier 200 through the two shoulder straps 300 to ensure safety. The adjustment buckle 400 is specifically designed to be a Japanese-shaped buckle or a "mu"-shaped buckle, which is convenient to use and economical and practical. Depending on the needs, some child carriers 200 also have two waist belts 700 symmetrically arranged on the left and right opposite sides of the seat body 500's seating area, and a crotch belt 800 positioned relatively centrally within the seat body 500's seating area, corresponding to the position between the child's legs. The two shoulder straps 300, the two waist belts 700, and the crotch belt 800 are each connected to a connecting buckle 900, thereby being detachably connected to the seat body 500 via the connecting buckle 900. During use, the connecting buckle 900 is generally located at the child's waist and abdomen. More specifically, the head protection device 100 of the present invention is detachably wrapped around the exterior of the shoulder straps 300:

[0051] Combine Figure 1 and Figure 2The shoulder strap 300 has a first structure: it includes an upper shoulder strap 301 and a lower shoulder strap 302 that are connected to the adjustment buckle 400. The upper shoulder strap 301 and the lower shoulder strap 302 are connected to the upper and lower opposite sides of the adjustment buckle 400, respectively, and a gap 401 is defined between the upper shoulder strap 301 and the lower shoulder strap 302. The upper shoulder strap 301 includes an upper connecting end 301a and a lower connecting end 301b at its front and rear ends. The upper connecting end 301a is connected to the upper end 600a of the backrest 600, and the lower connecting end 301b is connected to the upper middle end 600b of the backrest 600 after passing through the adjustment buckle 400. The lower shoulder strap 302 has a connecting end 302a and a free end 302b at its front and rear ends. The connecting end 302a is connected to the base 500. Specifically, the connecting end 302a can be detachably connected to the connecting buckle 900 via a buckle connected to the connecting end 302a, thereby connecting the lower shoulder strap 302 to the base 21. After the free end 302b of the lower shoulder strap 302 is passed through the adjustment buckle 400, an adjustment portion 3021 is formed between the free end 302b and the adjustment buckle 400, and a connecting portion 3022 is formed between the connecting end 302a and the adjustment buckle 400. During use, the relative length of the connecting portion 3022 can be adjusted by pulling the adjustment portion 3021, thereby changing the length of the entire shoulder strap 300 to suit the needs of different children.

[0052] Combine Figure 1 and Figure 3 The main difference between the second structure of the shoulder strap 300 and the first structure is that the lower connecting end 301b of the upper shoulder strap 301 is folded upward after passing through the adjustment buckle 400 to the belt body connected to the upper shoulder strap 301, thereby forming a through hole 3011 between the lower connecting end 301b and the upper shoulder strap 301 on the opposite back side of the adjustment buckle 400. The other parts of the shoulder strap 300 of this structure are basically the same as those of the first structure and will not be explained in detail here. When in use, the length of the connecting part 3022 is adjusted by pulling the adjustment part 3021, thereby changing the length of the entire shoulder strap 300.

[0053] It should be noted that in both shoulder strap structures described above, the lower connecting end 301b of the upper shoulder strap 301 is fixedly connected to the corresponding upper middle end 600b of the backrest 600 or the body of the upper shoulder strap 301, such as by sewing, using a Japanese-style buckle, or a mesh-shaped buckle. The upper connecting end 301a of the upper shoulder strap 301 can be sewn to the upper middle end 600a of the backrest 600, or removably connected to the backrest 600 via a buckle, resulting in a relatively simple structure. Of course, the upper connecting end 301a can also be passed through the backrest 600 and retracted into a webbing retractor located on the back of the backrest 600, thereby increasing the length of the shoulder strap 300 and effectively improving the adaptability of the shoulder strap 300. In addition, although the shoulder strap 300 of the present invention lists the above-mentioned structure including the split upper shoulder strap 301 and the lower shoulder strap 302, it is not limited to this. When the shoulder strap 300 is simplified to an integrated structure connected between the seat 500 and the backrest 600, the head protection device 100 of the present invention only needs to be still wrapped around the outside of the shoulder strap 300 and the adjustment buckle 400, and be engaged with the adjustment buckle 400 and the shoulder strap 300 at the adjustment buckle 400, so as to achieve no relative sliding.

[0054] The following combination Figures 2 to 8 , the structure of the first embodiment of the head protection device 100 of the present invention is described:

[0055] See Figure 4 and Figure 5 The head protection device 100 includes a guard plate 10 and a connecting piece 20 and a positioning piece 30 provided on the guard plate 10. The left and right side ends of the guard plate 10 are detachably connected by the connecting piece 20, so that it can be mounted on the outside of the shoulder strap 300 and the adjustment buckle 400. The positioning piece 30 is used to be clamped with the adjustment buckle 400 or / and the shoulder strap 300 connected to the adjustment buckle 400, so that the adjustment buckle 400 and the shoulder strap 300 connected to the adjustment buckle 400 are always wrapped in the guard plate 10. When in use, first place the head protector 100 between the backrest 600 and the shoulder strap 300, and align it with the position of the adjustment buckle 400. Then, after the positioning piece 30 is engaged with the adjustment buckle 400 or / and the shoulder strap 300 wrapped around the adjustment buckle 400, bend or roll up one of the relatively left end and the relatively right end of the guard plate 10 toward the other, so that the left and right side ends of the guard plate 10 are connected or overlapped, and are connected and fixed by the connecting piece 20, so that it can be conveniently and quickly put on the outside of the adjustment buckle 400 and the shoulder strap 300 wrapped around the adjustment buckle 400. Among them, in this embodiment, the guard plate 10 is arranged relatively along the longitudinal direction of the shoulder strap 300, so as to wrap around the outside of the adjustment buckle 400 and the shoulder strap 300 connected to the adjustment buckle 400, as well as the outside of the extension of the shoulder strap 300 connected to the connection. The guard plate 10 is relatively long, so that it can wrap around the outside of a longer range of the shoulder strap 300, which is safer and more comfortable to use.

[0056] See Figure 4 and Figure 5 The protective plate 10 is sheet-shaped, roughly rectangular, relatively soft and has a certain degree of elasticity. Specifically, the protective plate 10 includes a wrapping layer 11 and a fitting layer 12 that are sewn together as one. The wrapping layer 11 is used to contact the shoulder strap 300 and the adjustment buckle 400, and the fitting layer 12 is used to contact the head and neck of the child. Specifically, the protective plate 100 also includes a buffer layer (not shown in the figure because it is hidden between the wrapping layer 11 and the fitting layer 12). The buffer layer is arranged between the wrapping layer 11 and the fitting layer 12, and the wrapping layer 11, the buffer layer and the fitting layer 12 are sewn together as one. Among them, a buffer layer can be provided on the side of at least one of the wrapping layer 11 and the fitting layer 12 opposite to the other, that is, the wrapping layer 11 and / or the fitting layer 12 itself has a buffer layer. Of course, it is also possible to add a buffer layer and sew it together with the wrapping layer 11 and the fitting layer 12. In order to facilitate processing and use, the edges of the wrapping layer 11 and the bonding layer 12 can be sewn together as one. A filling port 111 is provided on the wrapping layer 11, and the buffer layer can be removably filled between the wrapping layer 11 and the bonding layer 12 through the filling port 111, thereby facilitating disassembly and washing, and making use healthier and more hygienic. It should be noted that when the wrapping layer 11 and / or the bonding layer 12 itself has a buffer layer, or when the buffer layer is sewn together with the wrapping layer 11 and the bonding layer 12, the filling port 111 corresponds to an indentation line sewn on the central axis of the guard plate 10, thereby facilitating the bending of the guard plate 10. The wrapping layer 11 and the bonding layer 12 can be made of at least one of fiber fabric, cotton material or leather material, and the buffer layer can be made of at least one of latex, memory foam or silicone material.

[0057] See Figure 5 The connectors 20 are specifically disposed at the edges of the opposite left and right ends of the guard plate 10. There may be multiple connectors 20, and the multiple connectors 20 may be spaced apart along the longitudinal direction of the guard plate 10. This allows the guard plate 10 to be more securely mounted on the shoulder strap 300 through the provision of multiple connection points. Specifically, the connectors 20 are any of a detachable fixing buckle and fixing hole, a buckle, a cord, and Velcro. In this embodiment, the connectors 20 are snap fasteners, comprising a male snap 21 and a female snap 22 spaced apart along the transverse width of the guard plate 10. By engaging or disengaging the male snap 21 and the female snap 22, the guard plate 10 can be simply and conveniently attached to and detached from the shoulder strap 300, providing ease of use and effectively reducing manufacturing costs.

[0058] See Figure 4 and Figure 5The positioning member 20 can be engaged with the shoulder strap 300 along the width of the shoulder strap 300. Specifically, in this embodiment, the positioning member 30 includes a snap-on tab 31 provided on the guard plate 10. The snap-on tab 31 is configured to engage the shoulder strap 300, which is connected to the adjustment buckle 400, from the front or back sides thereof. Specifically, the snap-on tab 31 engages with the upper shoulder strap 301 of the shoulder strap 300. Specifically, the edge of the left or right side of the guard plate 10 is recessed toward the opposite side to form a notch 13. This notch 13 forms the snap-on tab 31 on the guard plate 13. The notch 13 is located at the upper end of the left or right side of the guard plate 10, with the closed end of the notch 13 located near the centerline of the guard plate 10. The width of the notch 13 corresponds to the thickness of the shoulder strap 300, thereby facilitating the engagement between the snap-on tab 31 and the shoulder strap 300.

[0059] See Figure 4 and Figure 5 Preferably, the positioning member 30 further includes a closure member 32 disposed at the open end of the notch 13. The closure member 32 is used to open and close the open end of the notch 13, thereby strengthening the engagement between the engaging piece 31 and the shoulder strap 300. Specifically, the closure member 32 is any one of a removable fixing buckle and fixing hole, a buckle, a strap, and a Velcro. In this embodiment, the closure member 32 is a Velcro, comprising a mother sticker 321 and a daughter sticker 322 disposed on opposite side walls of the notch 13. By attaching or detaching the mother sticker 321 and the daughter sticker 322, the notch 13 can be opened and closed simply and conveniently, making it easy to use and effectively reducing manufacturing costs.

[0060] See Figure 4 and Figure 5 The head protection device 100 of the present invention also includes a stopper 40. The stopper 40 is sewn onto the protective plate 10 below the positioning member 30 and has a space for the shoulder strap 300 to pass through. This constrains the shoulder strap 300 within the protective plate 10, further strengthening the connection between the protective plate 10 and the shoulder strap 300 and limiting the sliding direction of the shoulder strap 300, thereby making the shoulder strap 300 more uniform overall. Specifically, the stopper 40 is annular or semi-annular in shape and exhibits a certain degree of elasticity. In this embodiment, the semi-annular stopper 40 is sewn onto the protective plate 40 at both ends, thereby creating a space between the stopper 40 and the protective plate 10 for the shoulder strap 300 to pass through, thereby reducing manufacturing costs.

[0061] Combine Figure 2 、 Figure 5 and Figure 6When the head protection device 100 of this embodiment is used on the child carrier 200 having the shoulder strap 300 of the first structure, the protective plate 10 is detachably wrapped around the adjustment buckle 400 and the upper shoulder strap 301 connected to the adjustment buckle 400, the adjustment portion 3021 and the connecting portion 3022 of the lower shoulder strap 302. The upper shoulder strap 301 located between the upper and middle ends 600b of the backrest 600 and the adjustment buckle 400 is inserted into the notch 13, so that the snap-fitting piece 31 is snap-fitted to the upper shoulder strap 301 connected to the adjustment buckle 400 at the back side of the adjustment buckle 400, and the snap-fitting surface 311 where the snap-fitting piece 31 is snap-fitted to the upper shoulder strap 301 is flat. When the adjustment portion 3021 is pulled to adjust the length of the shoulder strap 300, the engaging piece 31 is always engaged with the upper shoulder strap 301, so that the adjusting buckle 400 and the adjusting portion 3021 and connecting portion 3022 of the upper shoulder strap 301 and the lower shoulder strap 302, which are connected to the adjusting buckle 400, are always wrapped in the protective plate 10, making it safe and comfortable to use. The engaging effect is further improved when used in conjunction with the closure member 32, and the use effect is further improved when the adjusting portion 3021 and connecting portion 3022 of the lower shoulder strap 302 on the adjusting buckle 400 are inserted into the limiting member 40.

[0062] Combine Figure 2 、 Figure 5 and Figure 7 When the head protection device 100 of this embodiment is used on the child carrier 200 having the shoulder strap 300 of the first structure, another snap-on method can be used. Figure 6 The difference between the illustrated engagement method and the illustrated engagement method is that the engagement position of the engagement piece 31 and the upper shoulder strap 301 is different. In this case, the upper shoulder strap 301 located between the lower connecting end 301b and the adjustment buckle 400 is inserted into the notch 13, and the engagement piece 31 is engaged with the upper shoulder strap 301 at the loop-in end A of the adjustment buckle 400 on the opposite front side of the adjustment buckle 400. That is, the engagement piece 31 is engaged at a position between the upper shoulder strap 301 and the loop-in end A of the adjustment buckle 400, so that the engagement piece 31 is always engaged with the upper shoulder strap 301 at the adjustment buckle 400, thereby ensuring that the adjustment buckle 400 and the upper shoulder strap 301, the adjustment portion 3021, and the connection portion 3022 of the lower shoulder strap 302 are constantly enclosed in the protective plate 10, making the wearer safe and comfortable. In this specific embodiment, the engaging surface 311 of the engaging piece 31 is preferably an inclined surface, thereby effectively improving the firmness of the engaging. At this time, if the closing member 32 and / or the limiting member 40 are used in conjunction with the engaging piece, the engaging effect is better.

[0063] Combine Figure 3 、 Figure 5 and Figure 8 When the head protection device 100 of this embodiment is used on the child carrier 200 having the shoulder strap 300 of the second structure, Figure 6The difference in the illustrated snap-fit ​​method is that, while the snap-fit ​​piece 31 is still snap-fitted to the upper shoulder strap 301 wound between the adjustment buckle 400 and the lower connecting end 301b on the opposite back surface of the adjustment buckle 400, the snap-fit ​​piece 31 is specifically inserted into the through-hole 3011, and the notch 13 is snap-fitted to the upper shoulder strap 301 wound between the adjustment buckle 400 and the lower connecting end 301b. This double snap-fit ​​method effectively enhances the secureness of the snap-fit ​​connection. In this case, the snap-fit ​​effect is further enhanced when used in conjunction with the closure member 32 and / or the stopper 40. When the buckle 400 is in the locked position, the buckle 31 is in the locked position, and the buckle 31 is in the locked position, so that the buckle 31 is locked with the buckle 301 at the buckle 400.
