Abstract

A child stroller foldable extension bracket, installed on a child stroller and having two states, an unfolded state and a folded state. The extension bracket, when in the folded state, can be hidden under a main body bracket of the child stroller, and the child stroller can be folded as originally designed; when the extension bracket is in the unfolded state, a U-shaped support bar (2) and convex crossbar (3) thereof, together with child stroller main body front support bars, respectively forming a triangular structure when viewed from the left and right of the child stroller. When unfolded, the extension bracket is used for supporting the legs of a child, allowing larger toddlers to likewise lie flat. The present design can be applied to child strollers having various forms of main body brackets, and allows a lightweight portable child stroller bassinet to reach a length of 100 to 130 centimeters.

Description

一种儿童推车加长支架Extended support for children stroller 技术领域Technical field
本发明涉及儿童用品技术领域，具体涉及一种一种儿童推车加长支架。The invention relates to the technical field of children's products, in particular to an extended support for a stroller.
背景技术Background technique
现有技术中的儿童推车，当儿童需要躺下时，均采用翻起脚托的形式加长以便幼儿平躺。由于推车结构与尺寸限制，脚托翻起一般仅可增加推车15厘米左右长度。整个儿童推车的车篮长度含脚托一般不大于90厘米，轻便型儿童推车通常含脚托不大于80厘米，这对于较大幼儿（身高80厘米以上）往往尺寸不足，使得其睡觉时无法平躺，足部往往悬吊在推车外，既不安全，也影响幼儿舒适度，且不便于冬季保暖；此外也有单独出售的加长脚托，普遍使用固定带或魔术贴固定在现有推车的扶手上，由于下方没有支撑结构，此类脚托往往不够稳定，承重较差，幼儿躺下后腿部易下坠。The child strollers in the prior art, when the child needs to lie down, are extended in the form of turning up the footrest so that the child lie flat. Due to the structure and size of the cart, the footrest can generally only increase the length of the cart by about 15 cm. The length of the basket of the entire stroller including the footrest is generally not more than 90 cm, and the lightweight stroller usually includes the footrest not more than 80 cm. This is often insufficient for older children (over 80 cm in height), which makes them sleepy Unable to lie flat, the feet are often suspended outside the stroller, which is not safe, affects the comfort of children, and is not convenient for keeping warm in winter; in addition, there are also extended foot rests sold separately, which are generally fixed to the existing Because there is no supporting structure on the armrest of the stroller, this kind of foot rest is often not stable enough, and the weight bearing is poor, and the legs of the baby are easy to fall after lying down.
技术问题technical problem
现有的自重4公斤以内的轻便型儿童推车其车篮长度普遍不大于80厘米，因为按照现有的设计，若需要增加车篮长度则会大幅度增加儿童推车自重。即使是较笨重的车型，自重已经达到惊人的7公斤以上，也仅能提供95厘米以下的车篮长度。考虑到头部空隙，实际上90厘米身长以上的幼儿已经不能完全伸直平躺，只能蜷缩或悬吊足部。这对幼儿安全性、保暖性和舒适性均带来不良体验。The basket length of the existing lightweight strollers with a weight of less than 4 kg is generally not greater than 80 cm, because according to the existing design, if the length of the basket needs to be increased, the weight of the stroller will be greatly increased. Even for the heavier models, their own weight has reached an astonishing 7 kg or more, and they can only provide a basket length of 95 cm or less. Taking into account the head gap, in fact, children over 90 cm in length can no longer lie completely straight and can only curl up or hang their feet. This brings a bad experience to the safety, warmth and comfort of young children.
现有的儿童推车制造技术更倾向于解决较小幼儿的出行问题，事实上，较大幼儿会更频繁的跟随照料者去离家较远的地方出行。这使得他们的午休只能在不够舒适的儿童推车上进行浅度睡眠，随时可能因足部的充血或晃动而醒来，继而因睡眠不佳而哭闹，导致不愉快的出行体验。因此，迫切的需要在现有推车技术上进行改良，以便解决较大幼儿出行问题。The existing stroller manufacturing technology is more inclined to solve the travel problem of younger children. In fact, older children will follow their caregivers more frequently to travel far away from home. As a result, they can only sleep lightly on a stroller that is not comfortable enough for their lunch break. They may wake up at any time due to congestion or shaking of their feet, and then cry because of poor sleep, resulting in an unpleasant travel experience. Therefore, there is an urgent need to improve the existing cart technology in order to solve the travel problem of older children.
本发明是客服现有技术的不足之处，提供一种设计简单、安全稳固、适宜于较大幼儿平躺的、儿童推车可折叠加长支架的设计方案及其图纸。该加长支架呈折叠状态时，隐藏在儿童推车主体支架下，儿童推车可以按原有方式折叠收车。该加长支架展开时用于支撑儿童腿部，使较大的幼儿也可以达到平躺。该设计可以使轻便型儿童推车车篮长度达到100-130厘米。The present invention is a shortcoming of the existing technology of customer service, and provides a design scheme and drawings of a foldable and elongated child stroller that is simple in design, safe and stable, and suitable for larger children lying flat. When the extended bracket is in the folded state, it is hidden under the main body bracket of the stroller, and the stroller can be folded and retracted in the original manner. The extended bracket is used to support the legs of the child when it is deployed, so that the older infants can also lie down. This design can make the length of the lightweight stroller basket reach 100-130 cm.

有益效果Beneficial effect
对于经常带幼儿出门的家庭，2岁以上的幼儿身长普遍在80厘米以上，带孩子旅行是个美好的计划，但孩子们并不会按照成人的规划行走、玩耍与休息。他们常常自行规划行走路线并且十分兴奋，不得不携带一辆儿童推车固定他们，以便按照计划路线旅行；他们也会突如其来的昏昏欲睡，此时一辆能让他们完全平躺的儿童推车可以使他们像睡在小床上一样舒适，也能让同行的成人放松身心体验旅途的乐趣。For families who often take young children out, children over 2 years old are generally over 80 cm in length. Traveling with children is a good plan, but children do not walk, play and rest according to the adult's plan. They often plan their walking routes by themselves and are very excited. They have to carry a stroller to fix them so that they can travel according to the planned route; they will also suddenly become sleepy when a child pushes them completely flat. The car can make them as comfortable as sleeping on a small bed, and it can also let the adults on the road relax and experience the fun of the journey.
