Infant stroller frame folding stand device

technical field

The present invention relates to a folding and standing device for the frame of infant and toddler carriages. A standing supporting part which can be unfolded and turned and has ground-reaching wheels is arranged between the foldable front and rear wheel frames, so that the foldable The rear frame stands by the front and rear support of the ground wheel and the rear wheel, and can still slide and move easily.

Background technique

Generally, the well-known baby stroller can be unfolded and used, and the size can be reduced after being folded to facilitate storage. At the same time, the baby stroller can stand upright after being folded, which is the best storage method, for example: CN201120421671, CN201110075757, CN201120111208, CN201110228886, CN200320120890, CN200520110313... and other patents, but the method of folding and standing is to raise the rear wheel frame together with the rear wheel, and then support it on the ground through the support bar under the wheel frame , so that there is a front-to-back relationship with the front wheels, so that the frame can stand after being folded, but the raised rear wheels make the center of gravity of the entire frame quite unstable, and there are doubts about easy toppling. Although the volume is reduced, the overall length becomes longer, and storage is difficult. At the same time, when the support rod is supported on the ground, it will also make it difficult to move the folded and standing frame. The operation of the rack is not easy to carry out.

In addition, as in the CN201520207188 patent, a standing device that can be turned and supported on the ground is installed between the foldable front and rear wheel frames of the vehicle frame, that is, after the current and rear wheel frames are folded, the standing device The turning point of the first upright pole and the second upright pole stands on the ground, so that the front and rear support is formed between the rear wheels to make the frame stand, but the upright pole of the standing device is supported on the ground, and the folded stand is also allowed The movement of the rear vehicle frame is difficult, which makes it difficult for the user to operate the mobile vehicle frame.

Or as in CN201110367215 patent, it is by folding the front and rear wheels of the front and rear wheel frame close together, still keeping the front and rear short distance standing on the ground, so that the folded frame can not only reduce the volume but also stand At the same time, it is also easy to push and slide to facilitate the movement of the folded frame. However, when the push rod handle is folded when the frame is folded, it will also be folded downward together, resulting in the folded frame being too low to use. The operator must lean over and bend over to carry out the pushing operation, especially when the user holds an object or a baby in one hand, it will cause inconvenience and difficulty in limb operation.

Contents of the invention

When the front and rear wheel frames are folded, the front folding rod is pushed outward by the rear folding rod to swing and turn, so that the ground wheel and the rear wheel are in a front and rear support. Stand the frame on the ground.

In the above-mentioned scheme, the front folding rod is swung out from between the front and rear wheel frames and abuts against the lower end of the front wheel frame.

In the above scheme, the front wheel frame includes a lower end of the front wheel frame on which the front wheel is installed, and a telescopic middle frame is pierced on the upper end of the front wheel frame, and a multi-stage telescopic positioning handle is pierced on the upper end of the telescopic middle frame. Bundle.

The beneficial effect of the present invention is that after the above-mentioned vehicle frame is folded, the rear wheel frame is moved closer to the wheel frame, and the front wheel is lifted higher than between the two rear wheels; Between the ground wheel and the rear wheel, a front-to-back support is formed on the ground, so that the frame can still slide and move after being folded and standing, so that the user can easily carry out the operation of moving after the frame is folded.
