Description

Folding roller device

The subject of the utility model is a folding roller device, which includes a handle, a connecting part, a steering rod, an upper frame, a lower frame, a front wheel and a rear wheel.

Alternative means of transportation that help reduce pollution and avoid traffic jams are playing an increasingly important role in urban transportation. Reducing pollution caused by transportation and promoting a healthy lifestyle are becoming increasingly important. In particular, vehicles that are fast to learn and can be carried on other public transportation are increasingly popular. The folding roller device described in the present invention is such a device that the folding roller device can even be taken on a bus after being folded, which means that it conforms to the development trend of urban transportation.

The prior art includes the following solutions. German Patent Document No. DE10033450 describes a folding roller comprising two parts connected to each other by a connecting piece and a connecting tube. However, the method of folding the rollers with larger wheels fails to achieve the desired purpose because this device requires a larger space after folding.

Document No. WO13014391 describes a foldable vehicle in which it can be folded by applying pressure. The folding method is very simple, because the roller can also be folded by feet, but when the roller has a larger wheel, it is not guaranteed that the folded size is small.

US Patent Document No. US2009115167 applies a solution to an electric scooter so that wheels are folded adjacent to each other, but this solution is not suitable for rollers.

Patent Document No. WO2006032507 describes a folding roller in which the frame is equipped with a plate. This solution has a folding steering rod. However, this patent does not have a support member turned outwards during folding, the steering member itself may not be folded, and the size in the folded position is quite large, while the frame is folded into two parts instead of three parts.

Patent Document No. WO2008062109 describes a folding bicycle in which the frame is composed of two parts, a front frame part and a second frame part. The frame can be opened and folded using a portion whose axis is parallel to the wheel plane, so that the front frame portion and the second frame portion and the front and rear wheels of the bicycle move adjacent to each other. However, similar to the previous solution, the frame is folded into two parts instead of three parts, the size in the folded position is quite large, and there is no supporting member that will turn out during folding.

U.S. Patent Document Nos. US9197144B2 and US9718512B2 describe a folding vehicle, but these solutions do not have support members that will turn out during folding, and the wheels are inward toward the frame.

Patent documents No. DE102009055222 and WO2017123158 describe other solutions related to folding rollers.

In summary, it is clear that there are many known solutions for folding rollers; however, these solutions are mainly applicable to folding vehicles with small wheels, and these folding vehicles may not be folded to very small sizes. However, devices with larger wheels provide greater comfort for users, and they are also more practical. Therefore, the prior art does not include any solution that can provide long-term stability of the folding method.

The purpose of the new model is to eliminate the shortcomings of the known solutions and to realize a design through which a folding wheel with a larger wheel is produced, so that the folding wheel can be folded to a position requiring only a small space . Another purpose is to quickly and easily fold the roller without tools. In the folded position, such a folding roller with a larger wheel should be suitable for a small space, so that it can even be installed in the rear trunk of the vehicle or can be transported by public transportation. It is very important that the rollers can be safely locked in either the folded position or the open position.
