This application is a continuation of International Patent Application No. PCT/IT06/000180 filed on Mar. 23, 2006 which claims benefit of Italian Patent Application No. RM2005A000143, filed on Mar. 24, 2005, all of which are incorporated herein in their entirety.
1. Field of the Invention
This industrial invention patent regards a magnetic system which when placed within padlock and lock mechanisms allows these mechanisms to be blocked or unblocked at the discretion of the user.
In particular this device includes a magnetic system which by use of a device protected by a personalized code can either permit or prevent the movement of a mechanism to which it is applied.
2. Brief Description of the Art
This industrial invention patent constitutes an innovation in the field of common unlocking systems for padlocks and locks and in particular for those used for doors. Reference to this type of use will later be made but this will only be done for example purposes since the same principles are applicable for other applications (for example safes and locking devices in general).
With current technology magnetic unlocking systems for padlocks and locks are composed of devices that include magnetic components in the key. These keys can pose a serious health risk to patients with internal medical devices that are sensitive to magnets such as pace makers. Furthermore transporting such keys together with credit cards or cards with magnetic stripes can alter the magnetic properties of both the keys and the cards.
The device being presented for this industrial invention patent develops current systems in that the device only contains magnetic components in the mechanism of the padlock or lock applied to the fitting and not in the keys body.
Consequently the specific object in question of this industrial invention patent is a magnetic system for the unlocking of padlocks and locks characterized by the fact that it includes:
The invention will now be described in an illustrative but not limited manner as being part of an already generally known device for covering padlocks and locks but it must be understood that this only has the aim of making the clearer the presentation description and enunciation. The design patent will now be illustrated in its preferred but not exhaustive design form with particular attention being paid to the attached drawings in which:
The preferred design form of the industrial invention patent will now be described in detail. As illustrated in
A lock-cover element (11). The lock-cover element (11) has several sub-components which are:
The magnet sensitive (20/C) coding-pins (20) located in the key-body (18) attract the magnet pairs located in the holes on the internal surface of the covering element (13) and the plate element (15) thus moving the mating surface of the magnet pairs to the same level as that of the covering element (13) and of the plate element (15) surfaces while the magnet insensitive (20/D) coding-pins (20) leave immobile the pairs of magnets on the inside of the lock-cover (11), the mating surfaces these already being at the same level as those of the covering element (13) and plate element (15) surfaces.
The sequence of necessary operations for gaining access to the underlying lock is as follows:
This invention has been described in an illustrative but nevertheless not a limited manner according to its preferred design form but it must be understood that any variations and/or modifications may be made without leaving the relative ambit of protection as defined in the attached claims.
