DE2810016A1 - Car key heater - for thawing frozen locks by battery or chemically produced heat - Google Patents

Abstract

A key to open frozen car doors or frozen petrol tank locks in winter can be heated up by pushing it, with the ward up, into a sleeve containing dry or rechargeable batteries. The pressure of a button makes a contact and a heating element heats up the key. Instead of the electrical system, the heat can be developed by crushing a plastic cartridge containing water and carbide in separate compartments. The sleeve can also be designed as a permanent key head.

Description

Key warmers

In car locks it is known that these locks can freeze. This is often the case with the door locks and with the fuel tank cap in winter. In addition to the key system, the guard locking is also affected by the freezing. Around to insert a key into the keyhole and also to lock the guard actuate, a significant amount of heat is required for frozen locks. today the driver helps himself by warming up the key and repeatedly inserting it into the Keyhole.

This does not, however, release the guard locking. It is also possible to spray a spray into the lock. But the spray is in the car, so that the driver of the car cannot approach.

There are electric key warmers. The key is in a sleeve inserted and the key bit is warmed up in the sleeve.

The heated key can then be inserted into the keyhole earth. If the lock cannot be opened, this process must be repeated -rend.

The invention relates to a key heater consisting of a sleeve (X) exists. In this case are one or more dry cell batteries or rechargeable batteries Batteries introduced. One or two heating plates or heating coils or other already common heating elements are inside this sleeve. Be at the push of a button (K) These litz elements are put under tension and heat up and give off the resulting Heat off the key.

The key can be put in the key warmer with the beard facing up be plugged. It is possible to design the key warmer as a handle and, if desired, to connect it to the key as permanently as it does now with the common plastic pad happens. The operation is now done in the Kind of that the key is touched by the beard and put into the key warmer Will. Then the key warmer is touched and the beard of the key becomes put in the keyhole. If the lock is frozen, so will the lock thawed by heating the key. The driver presses the button (K) and at the same time he tries to open the lock. This must be the Drivers do so until the key can be turned and the locking mechanism is resolved.

However, chemical energy can also be used as an energy source. H20 (water) and CaC2 (carbide) are separated in the sheath. The sleeve with chemical agents are placed in the key heater at (K). The key protrudes with the beard from the key warmer. The operator presses the button (K) and destroys the case. Water and carbide flow into one another. There is warmth which is given to the key and thus to the lock. But it can also use ampoules with other chemical substances, e.g. ammonia and water Etc.

Claims (1)

Claim 1 key warmers, characterized in that the , Key with its handle inserted into a sleeve or in this cavity is permanently attached so that the key warmer is also the key handle is. The key stick protrudes from the key warmer. The key is brought about by means of a movable electrical source through a release button Heating resistors brought to a higher temperature. Patent claim 2 characterized in that key warmers according to Claim 1 is not heated with an electrical energy source, but with a chemical energy source by bringing two substances together, e.g. by Combination of H2O with CaC2 or other chemical substances.
