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

Extended support for children stroller

Technical field

The invention relates to the technical field of children's products, in particular to an extended support for a stroller.

Background technique

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.

technical problem

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.

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.

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.

Technical solutions

To achieve the above objective, the technical solution adopted by the present invention is:

An extended support for a child stroller is composed of an angle limiting device, a U-shaped brace, a convex crossbar and a folding plate, and is installed on the stroller. The angle limiting device is fixed at a position near the bottom of the front struts of the stroller body (the struts on both sides of the foot pedal of the body bracket), and is used to limit the turning angle of the U-shaped struts; The two ends of the strut are installed at the position near the bottom of the front strut of the stroller body, and the middle section can be flipped and moved; the two ends of the convex crossbar are installed on the body bracket of the stroller or the On the U-shaped brace, the middle section can be flipped and moved, and the two ends of the middle section are equipped with additional connecting devices such as buckles or hooks; the folding plate is multi-folded, and the outer surface may be covered with soft fabrics or summer mats, etc., with additional Anti-scattering devices such as Velcro, concealed buckle or fixed belt.

further, The elongated bracket has two states: unfolded and folded. In the folded state, the folding plate is in a multi-folded state, and is stored above the pedals of the stroller, and is provided with additional anti-scattering devices such as Velcro and concealed Buckles or fixing straps are fixed to prevent unraveling; the U-shaped struts and convex cross-bars are in a folded state, hidden behind the folding board, and kept parallel or similar to the front struts of the stroller body Parallel direction, and is limited by additional anti-overturning devices such as Velcro and fasteners to prevent overturning.

Further, in the unfolded state, the convex crossbar is in a horizontal or nearly horizontal state, and connects the seat part of the child stroller and the middle section of the U-shaped strut, and is provided by an additional connecting device such as a buckle. Or the hook is fixed; the U-shaped brace and the front brace of the stroller body form an opening angle of 45-100 degrees, and the maximum angle is limited by the angle limiting device. The folding board is in an opened state, placed on the convex crossbar, and further fixed on the convex crossbar by additional anti-scattering devices such as Velcro, concealed buckle or fixing strap. The U-shaped brace, the convex crossbar, and the front brace of the stroller body respectively form a triangular structure in the left and right side views of the stroller.

Beneficial effect

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.
