AI Technical Summary

Problems solved by technology

Even though the seal covers the entire entrance of the cylinder lock, the seal must be removed before the lock can be used, making the solution cumbersome to use
Seals may also come off or be missing

Embodiment Construction

[0017] Now refer to figure 1 , which illustrates a method for waterproofing a lock device according to a non-limiting embodiment of the present invention.

[0018] In contrast to prior art sealing methods that prevent water from entering the lock, in the present invention no attempt is made to prevent water from entering. Instead, water protection is provided by applying a hydrophobic coating to some or all of the interior components of the lock arrangement. An example of applying a hydrophobic coating is given below.

[0019] In one embodiment, a hydrophobic coating is applied to the internal components of the lock device prior to assembling the internal components in the lock device. For example, for a mechanical lock device, the movable (eg, rotatable) cylinder, cylinder pin, flat pin, spring, and bolt throwing elements (such as latches, cams, rods, etc.) are coated Hydrophobic coating, and then assembled in the lock. For electromechanical or mechatronic locking devices...

Abstract

A method for waterproofing a lock device includes applying a hydrophobic coating on internal components of a lock device, the components including a movable plug and plug pins.

Description

technical field [0001] The present invention relates generally to lock devices, such as mechanical locks and electromechanical locks, and more particularly to the use of hydrophobic coatings to protect such locks. Background technique [0002] In many instances it is desirable to prevent water from entering a cylinder lock or other similar locking device. For example, water entering a cylinder lock can cause corrosion of the lock cylinder, cylinder pins or flat pins and prevent proper operation of the cylinder lock. In electromechanical locks, there is the additional problem of water contacting the electrical circuit and causing a short circuit. [0003] The problem of making cylinder locks waterproof has been solved in the prior art. A typical prior art solution is to use a sealing device, such as a seal, gasket or other sealing member, which seals the entrance to the keyhole in the lock. This solution is flawed for several reasons. For example, if the seal only covers ...
