WO2015183142A1 - Easily installable / removable car wheels - Google Patents

Abstract

The present invention relates to easily installable and removable metal wheels comprising a toothed wheel and a lock at the centre thereof. The wheel can be made of any metal and can generally take the form of any current car wheel. The invention consists of a wheel comprising two parts (a mounting base and a central lock), which are secured to the wheel hub and fit securely in the hollow at the centre of the wheel. The central hollow in the wheel comprises a sliding toothed wheel comprising lateral slots for the lock teeth, and to which corresponds reciprocally a sliding toothed wheel with lateral slots for the teeth of the lock which is secured within the mounting base, such that the mounting lock can be unlocked with a special key and the security teeth of the lock come out of opposing slots in the mounting base and the hollow at the centre of the wheel. When the security teeth enter the slots, the wheel can be removed only after it has been unlocked and the security teeth retracted from the opposing lateral slots. The special key can be the ignition key (switch) itself or a similar key. Therefore, the user can easily remove and install the wheel without using a traditional wheel brace, thereby greatly reducing the time and effort involved in replacing a punctured tyre (Figure 1).
