Portable electric heating device for thawing motor vehicle door locks |
摘要 |
A compact portable device energizable from a motor vehicle battery for thawing frozen motor vehicle door locks includes an electrically heated thawing stick sized for insertion into the keyhole of a frozen lock. The stick comprises a hollow metal body enclosing a resistance wire. One end of the wire is connected to the stip of the metal body and the other end is connected to an elongated cable terminating in a plug insertable into an electrical socket on the vehicle connected to the vehicle battery. The thawing stick is secured to a hollow protective case modeled in the form of a flat key end and provided with a key ring. The case has an open narrow side through which the cable can be inserted for storage within the case during non-use periods and the stick is pivoted for movement from a non-use position covering the open side of the case to an extended use position.
