Description

Technical Field

[0001] The invention relates to the technical field of high-speed rail seat armrest stools, in particular to a high-speed rail seat armrest stool for children. Background Art

[0002] In today's society, it is very common for adults to bring children on high-speed trains. However, during long-distance travel, since children need to be accompanied by adults at all times, adults need to share seats with children. The usage methods include adults holding children and using seats together or adults and children taking turns using seats. In addition, some passengers will bring portable benches to use in high-speed rail scenarios.

[0003] In response to the above problems, Chinese patent CN213384247U discloses a child seat for high-speed rail, which is installed inside an adult seat to meet the needs of children. Although this design alleviates the problem of space utilization for children to a certain extent, it requires structural adjustments to the existing adult seat, which not only increases costs, but may also interfere with the original seat function.

[0004] Furthermore, in principle, solutions for detachable child seats are known in the prior art. Although certain progress has been made in motor vehicle seats, child carriers (waist stools), and portable benches, when trying to apply them to high-speed rail seats, a variety of mismatching problems are revealed. For example, the design and spatial layout of high-speed rail seats are significantly different from those of motor vehicle seats, which makes it difficult for child seats designed for motor vehicles to be directly adapted to high-speed rail seats. At the same time, although some child carriers or waist stools are easy to carry and use, their stability and safety are difficult to guarantee in a high-speed operating environment such as a high-speed rail, which may bring potential safety risks to children. Although portable benches can temporarily solve the problem of insufficient seats, they often lack consideration for the support and protection of children's bodies, so the known solutions still need to be improved.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a high-speed rail seat armrest stool for children to solve the problems existing in the above-mentioned prior art. On the basis of not changing the existing high-speed rail seat, a child support plate is installed on the high-speed rail seat, so that adults and children can sit on one high-speed rail seat at the same time, and the applicability, stability and safety are high.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-Figure 5 As shown, this embodiment provides a high-speed rail seat armrest stool for children, comprising:

[0036] The child carrying device includes a child support seat plate 1, which is similar to an L-shaped structure when viewed from the side and is integrally formed of a plastic material. Both sides of the child support seat plate 1 are provided with armrest corresponding parts, which are part of the child support seat plate 1 and whose shape matches the shape of the armrest of the high-speed rail seat.

[0037] The armrest fixing device is provided with two armrest fixing devices, and the armrest fixing device includes an armrest support shell 3, and the armrest support shell 3 is made of ABS engineering plastic to ensure that the armrest support shell 3 is strong and durable, while reducing the overall weight. The two armrest support shells 3 are respectively slidably connected to the corresponding parts of the two armrests, and the armrest support shells 3 can be used to be installed on the armrests of high-speed rail seats.

[0038] The positioning device is installed between the armrest supporting shell 3 and the corresponding part of the armrest, and the positioning device can realize the positioning of the armrest supporting shell 3.

[0039] The binding device is installed on the armrest support shell 3, and is used to bind the armrest support shell 3 and the armrest of the high-speed rail seat together.

[0040] In actual use, an adult can first sit on a high-speed rail seat, and then place the child support plate 1 on the armrest of the high-speed rail seat facing him / her. Specifically, the armrest support shells 3 on both sides are respectively mounted on the armrests of the high-speed rail seat on both sides of the adult, and then the armrest support shells 3 are tied together with the armrests of the high-speed rail seat by a binding device, thereby fixing the armrest fixing device. Then, the sliding connection between the child support plate 1 and the armrest fixing device is used to adjust the front and rear position of the child support plate 1, and finally the positioning device is used to fix the child support plate 1.

[0041] In this embodiment, the armrest corresponding part and the armrest supporting shell 3 are both n-shaped structures (or called arch or inverted U-shape). The reason for this configuration is to match the shape of the armrest of the high-speed rail seat, so as to cover and better fit the armrest of the high-speed rail seat, thereby improving the stability of the entire device.

[0042] In this embodiment, a rounded rectangular gripping through hole is provided on the child support seat plate 1 , and the purpose of providing the gripping through hole is to facilitate grasping by an adult, thereby facilitating the carrying of the child support seat plate 1 .

[0043] In this embodiment, an armrest buffer pad 4 is installed on the inner side of the armrest support shell 3. The shape of the armrest buffer pad 4 matches the shape of the armrest support shell 3, and both are n-shaped structures. The armrest buffer pad 4 is made of a soft, environmentally friendly, non-toxic sponge material. Furthermore, the outer surface of the armrest buffer pad 4 can also be covered with a layer of breathable and wear-resistant fabric. The purpose of providing the armrest buffer pad 4 is to avoid problems such as wear caused by direct contact between the armrest support shell 3 and the armrest of the high-speed rail seat, and to avoid improving the comfort of the device.

[0044] In this embodiment, a limiting slide groove is provided on one side of the armrest support shell 3 close to the center of the child support plate 1, and a limiting slider 8 is provided at a corresponding position on the inner side surface of the corresponding part of the armrest, and the limiting slider 8 is slidably connected in the limiting slide groove.

[0045] Alternatively, a limiting sliding block 8 may be provided on the armrest supporting shell 3, and a limiting sliding groove may be provided on the inner side surface of the corresponding portion of the armrest.

[0046] Through the sliding cooperation between the limiting sliding block 8 and the limiting sliding groove, not only can the sliding connection between the armrest supporting shell 3 and the corresponding part of the armrest be achieved, but also the armrest fixing device can be supported.

[0047] In this embodiment, the positioning device includes a positioning button 5, a positioning rod 6, a positioning spring and a positioning block 7. The positioning button 5 is a triangular button made of polypropylene (PP) material, and the positioning block 7 is made of nylon 66 (PA66) material to ensure good wear resistance and self-lubrication, reduce friction and increase service life. The positioning button 5 and the positioning block 7 are respectively fixed to the two ends of the positioning rod 6. The outer side of the armrest support shell 3 is provided with a positioning track 9, which can be understood as a rectangular shell, and the positioning block 7 moves inside the positioning track 9, and a plurality of positioning circular holes 10 and strip channels 11 are opened on one side of the positioning track 9, specifically three positioning circular holes 10 and two strip channels 11 are provided, and two adjacent positioning circular holes 10 are connected through the strip channels 11, and the positioning rod 6 is slidably connected in the strip channels 11. Of course, those skilled in the art can also adjust the specific number of positioning circular holes 10 and strip channels 11 according to actual needs, and are not limited to this one. The positioning spring is sleeved on the outer side of the positioning rod 6 , one end of the positioning spring abuts against the corresponding part of the armrest, and the other end of the positioning spring abuts against the armrest support shell 3 .

[0048] In actual use, when the positioning rod 6 slides in the position of the strip channel 11, the positioning spring is in a stretched state, and the armrest support shell 3 and the corresponding part of the armrest can slide relative to each other, thereby adjusting the front and rear position of the child support plate 1. When the positioning rod 6 moves to the positioning circular hole 10, under the stretching action of the positioning spring, the positioning block 7 is pulled out and positioned at the positioning circular hole 10. At this time, due to the limiting effect of the positioning block 7 and the positioning circular hole 10, the positioning rod 6 cannot move further, thereby positioning the child support plate 1. If you want to further adjust the position of the child support plate 1, you only need to press the positioning button 5 so that the positioning block 7 enters the positioning track 9 again, so that the positioning rod 6 can slide again, thereby adjusting the position of the child support plate 1.

[0049] In this embodiment, the positioning block 7 includes a first positioning cylinder and a second positioning cylinder. The diameter of the second positioning cylinder is larger than that of the first positioning cylinder. The diameter of the first positioning cylinder matches the inner diameter of the positioning circular hole 10 .

[0050] The purpose of this arrangement is that when the positioning block 7 moves to the position of the positioning hole 10, the first positioning cylinder will enter the positioning hole 10 to limit the child support plate 1, while the second positioning cylinder will not enter the positioning hole 10, thereby preventing the positioning block 7 from being completely separated from the positioning track 9.

[0051] In this embodiment, the binding device includes a first binding fixing webbing 12 and a second binding fixing webbing 13. The first end of the first binding fixing webbing 12 and the first end of the second binding fixing webbing 13 are respectively fixed to the two sides of the armrest support shell 3. The second end of the first binding fixing webbing 12 is installed with a male plug-in buckle 16, and the second end of the second binding fixing webbing 13 is installed with a female plug-in buckle 17. The male plug-in buckle 16 and the female plug-in buckle 17 can be plugged in. The male plug-in buckle 16 and the female plug-in buckle 17 are common plug-in buckle structures on existing school bags or backpacks, so their working principles will not be further described here.

[0052] In actual use, after the armrest fixing device is installed, the male head 16 and the female head 17 of the lock buckle located on both sides of the bottom of the armrest of the high-speed rail seat can be plugged in to bind the lower end of the armrest of the high-speed rail seat, thereby fully covering the armrest, thereby achieving fixation between the armrest fixing device and the seat armrest.

[0053] In addition, three or other number of binding devices may be provided on the armrest support shell 3 on each side, and the specific number may be adjusted according to the length of the armrest support shell 3 .

[0054] In this embodiment, one end of the armrest support shell 3 is rotatably connected with a rotating shaft 14, and the rotating shaft 14 is made of corrosion-resistant and high-strength stainless steel material to ensure smooth rotation and durability. In order to realize the rotatable connection of the rotating shaft 14, two or more rings are provided at the lower part of one end of the armrest support shell 3, and the rotating shaft 14 is rotatably connected to each ring. A webbing fixing member 15 is fixed on the rotating shaft 14, and the material of the webbing fixing member 15 is nylon material to ensure sufficient binding force and durability. The webbing fixing member 15 is connected to the first binding and fixing webbing 12 by sewing. The purpose of setting the rotating shaft 14 is that when the male head 16 of the plug lock buckle and the female head 17 of the plug lock buckle are plugged in, in order to better fit with the lower surface of the seat armrest, it is required that the male head 16 of the plug lock buckle, the plug lock, the female head of the first binding and fixing webbing 12, and the webbing fixing member 15 are preferably in a horizontal state, so the rotating shaft 14 is set to adjust the angle of the webbing fixing member 15 and the first binding and fixing webbing 12.

[0055] In addition, a nut is threadedly connected to each end of the rotating shaft 14, and the nut can be abutted against the ring to limit the axial direction of the rotating shaft 14. When the nut is tightened, the friction between the nut and the ring is large, and a friction resistance can be applied to the rotating shaft 14, making it difficult to rotate without external force.

[0056] The other end of the armrest support shell 3 is provided with a side groove, and one end of the second binding and fixing webbing 13 is fixed in the side groove, so as to achieve the fixation of the second binding and fixing webbing 13 and the armrest support shell 3.

[0057] In this embodiment, a seat cushion 2 is provided on the child support plate 1. The seat cushion 2 can be made of foam or sponge material to provide a good cushioning effect, relieve the pressure points that may be caused by long-term riding, and reduce the physiological discomfort felt by parents due to holding the child for a long time.

[0058] Furthermore, fixing ropes are provided on both sides of the seat cushion 2 , and fixing rings are provided on both sides of the child support plate 1 , and the fixing ropes are tied to the fixing rings, so as to fix the seat cushion 2 .

[0059] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
