Abstract

The present invention relates to children trolley fields, disclose the design scheme and its drawing of a kind of foldable lengthening bracket of children trolley.The lengthening bracket is installed on the children trolley, is had and is unfolded and folded two states.When the lengthening bracket is in folded state, it is hidden under children trolley main body rack, children trolley can be folded by original mode and be returned the vehicle to the garage and knock off.When the lengthening bracket is in unfolded state, the U-shaped strut, convex cross bar and the children trolley main body front strut constitute a triangular structure in the children trolley or so side view orientation respectively.The lengthening bracket is used to support child leg when being unfolded, and can achieve biggish child also and lies low.The design is suitable for the children trolley of various main body rack forms, and lightweight children trolley bicycle basket length is made to reach 100-130 centimetres.

Description

A kind of children trolley lengthening bracket

Technical field

The present invention relates to articles for children technical fields, and in particular to a kind of children trolley lengthening bracket.

Background technique

Children trolley in the prior art is all made of the form lengthening for digging footrest when children need to lie down so as to children Youngster lies low.Since cart structure and size limit, footrest, which is dug, generally can only increase by 15 centimetres of cart or so length.Entire children The bicycle basket length of cart is generally no greater than 90 centimetres containing footrest, and lightweight children trolley usually contains footrest and is not more than 80 centimetres, this For larger child (80 centimetres of height or more) often undersize, so that it can not lie low during sleep, foot is often suspended in It is both dangerous outside cart, child's comfort level is also influenced, and be not easy to winter warming；Furthermore also there is the lengthening footrest individually sold, It is generally fixed on using fixing belt or velcro on the handrail of existing cart, since lower section does not have support construction, such footrest is past Toward being not sufficiently stable, load-bearing is poor, and leg easily drops after child lies down.

Summary of the invention

The purpose of the present invention is providing in place of customer service the deficiencies in the prior art, a kind of design is simple, safety and firmness, is suitable for Design scheme and its drawing that larger child lies low, the foldable lengthening bracket of children trolley.The lengthening bracket is in folded state When, it is hidden under children trolley main body rack, children trolley can be folded by original mode and be returned the vehicle to the garage and knock off.The lengthening bracket is used when being unfolded In support child leg, it can achieve biggish child also and lie low.The design can make lightweight children trolley bicycle basket length Reach 100-130 centimetres.

To reach above-mentioned purpose, the technical solution adopted by the present invention is that:

A kind of children trolley lengthening bracket, the lengthening bracket limit device, U-shaped strut, convex cross bar and folding by angle Lamination is constituted, and is installed on children trolley.The angle limits device and is fixed on the children trolley main body front strut (master Two side brace of body support frame foot pedal) close to the position of bottom, for limiting the flip angle of the U-shaped strut；The U-shaped strut Both ends are installed in the children trolley main body front strut on the position of bottom, and activity may be reversed in middle section；The convex is horizontal Bar both ends be installed on the main body rack of the children trolley or the U-shaped strut on, middle section may be reversed activity, middle section both ends With additional attachment device such as fastener or hook；The folded sheet is more foldings, and outer surface may coat soft fabric or cool Seat etc., and with additional anti-de-registration apparatus such as velcro, hidden discount or fixing belt.

Further, the lengthening bracket unfolds and folds two states, and in a folded configuration, the folded sheet is in more Folded state is received in above the children trolley foot pedal, is consolidated by additional anti-de-registration apparatus such as velcro, hidden discount or fixing belt Determine to prevent from scattering；The U-shaped strut, convex cross bar are in overturning rounding state, are hidden in the folded sheet rear, protect Or less parallel direction parallel with the children trolley main body front strut is held, and by additional turnover prevention device such as velcro, card Fastener is limited to prevent from overturning.

Further, in the deployed state, the convex cross bar connects the children and pushes away in level or close to horizontality Vehicle seats position and the U-shaped strut interlude, and fixed by additional attachment device such as fastener or hook；The U-shaped support Bar and the children trolley main body front strut limit device by angle and limit maximum angle in opening 45-100 degree angle.Institute It states folded sheet in opened condition, is placed on the convex cross bar, and by additional anti-de-registration apparatus such as velcro, hidden discount or admittedly Determine band to be further secured on the convex cross bar.The U-shaped strut, convex cross bar and the children trolley main body front strut point A triangular structure is not constituted in the children trolley or so side view orientation.
