Description

Key system and drive lock Unidirectional and multidirectional blocking.

Object of the invention

The present invention concerns a system of unidirectional key and lock and lock Multidirectional, construction and simple operation, which prevents blockage of the lock due to foreign objects, and It allows opening without turning the key. Thanks to its symmetry, said key does not need prior orientation to its introduction in the lock.

Background of the invention

A lock is a mechanism incorporated into doors, drawer cabinets, chests, chests, etc., to prevent that can be opened without the key and thus protect its contents.

This mechanism can be operated by a metal key, usually steel. Currently, apart from mechanical locks, there are others such as electro-mechanical or electronic, in which the key can be a plastic or PVC card. The key fits in the lock through the hole enabled for it, called "eye", which is a hole normally located in the central part of the lock cylinder.

Currently, most locks with mechanical cylinders - with sawtooth or spanner wrenches points - and including among them those of the security doors and armored, they have stopped offering the security with which they were conceived because of the diffusion of techniques for opening the same, which pose an obvious risk to suffer access Unwanted, theft and theft.

In addition, for a key and lock system offer great security, it comprises a plurality of elements and mechanisms that make these high cost systems and complexity.

As is known, the keys commonly used in communities, homes, locks, etc., are keys toothed, so that on one of its sides of its axis it they find those teeth that fit the lock. Too there are cylinder keys, somewhat safer than previous. All of them have to be entered in the lock in the proper orientation, and need turning to operate them. This causes that sometimes, when the frame is very close to The door is a difficult task. Also when there are bodies strangers inside the lock, or when it is If it is damaged, the key may break force said turn. When this happens the complete lock usually become unusable

Description of the invention

The proposed invention is about a system of unidirectional key and lock and lock Multidirectional, easy accessibility, intuitive operation and high degree of security against the use of foreign objects such as picks or similar, with great mechanical and productive simplicity that generates cost savings in its manufacture.

It is a logical manufacturing system, which It includes pieces of simple construction and with a small number of elements that compose it.

The mode of operation is limited to entering the key and, without turning, press or pull the same key or lock to be able to be operated. The key and lock system also allows the unblocking of the mechanism due to objects strangers when applying a force in the same direction and / or sense of the key entry, being able to operate with the key itself, this being the most recommended and / or other object. This is achieved simply with the existence of a space after the tip of the key when introduced in its entirety. In addition, there is the possibility of the provision of a complementary hole for the It helps the relief of these foreign bodies.

The system includes key and lock. The key it comprises active parts equal in number as the number of bowlers arranged in the lock, so that when introduced in the housing for the key the bowlers will adapt to these active areas leaving the lugs outside the area that blocks the set. This key is symmetric in the active part around its main axis, so you don't have to take into account the orientation of the same in the introduction in the lock. The bowlers may be outdated and aligned or misaligned, around the axis where the key with which it would be achieved is located a multidirectional lock. Each cylinder is associated with a spring secondary. Before the key is inserted, the mechanism will be in closed position. By introducing and exerting a force on the same address as the one of the introduction of the key, the mechanism, and by ceasing to exert such force, a spring causes The mechanism returns to its initial position of action.

Description of the drawings

To complete the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of the practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1 shows a perspective view. of the key and lock system, with a section of the lock where the different elements of it are appreciated.

Figure 2.- shows a sectional side view of the main plane of the set, where the possible existence of a foreign body.

Figure 3.- shows a front section view of the system of the invention.

Preferred Embodiment of the Invention

The invention described herein is about a key system (1) and unidirectional lock (2) and multidirectional blocking. This system offers great security, accessibility and ease of manufacture and assembly.

This key (1) and lock (2) system provides a simple mechanism with simple elements and that behaves with great efficiency In this way, lock and unlock are achieved. by means of a key (1) that when fully inserted in the lock (2), get the mechanism unlock, needing subsequently a pressure in the same direction of introduction of the key (1) to activate the mechanisms until the unlock

The system comprises key (1) and lock (2). The key (1) is completely inserted into the lock (2). Bliss key (1) has a plurality of active parts (9) around of its main axis, where each one can adopt any dimension and configuration deemed appropriate for your operation, taking into account its place of action in the lock (2), that is, the slots (10) and / or cylinders (6). The active parts (9) are symmetrical with respect to the main axis, so that said configuration allows the insertion of the key (1) without Need to seek prior guidance.

The lock (2) is drive unidirectional, and comprises a fixed body (3) with a plurality of slots (10) and a movable body (4) with a housing (5) for the key (2), a plurality of bowlers (6) with and their lugs (8) corresponding and secondary springs (13), providing in addition to a main spring (7) acting between the fixed body (3) and the mobile body (4).

Before inserting the key (1) into the lock (2) the system is in the closed position or blocking. After inserting the key (1) into the lock (2), Unlocks, without needing a turn for its operation, facilitating large opening for example when the frame is very Stuck to the wall.

The bowlers (6) of the movable body (4) can be out of phase and aligned on the axis of said body (4) or may be out of phase misaligned on its surface, this it is, in the movable body (4) around the housing axis for the key (1), achieving in this second case greater security against foreign objects, such as picks or similar.

The main spring (7) mission is to maintain is to keep the system in its most delayed position whether there is key housed as if there was but no force was applied, and also, get the system back to its initial position if you stop applying force.

Being part of the bowlers (6) are the lugs (8) that are housed in the slots (10) of the fixed body (3), so that the system is locked when there is no key or not It is the right one, and unlocked when it is the correct key (1). These lugs (8) can be of variable geometry, although the most logical for its manufacture would be to arrange them in cylindrical form and smaller in diameter than the cylinder (6).

How to improve to prevent clogging of the lock, or breakage of the key (1) and lock (2) because of the existence of foreign objects inside the lock (2), there is a hole (11) for relief of foreign elements. Thus, when entering the key (1), the foreign body (12) would remain displaced by the axis of said key (1), without blocking the lock (2) and without preventing the correct positioning of the key (1) in the inside of the lock (2).
