Description

Magnetic tubular handle.

Object of the invention

The present invention as expressed in the set forth in this specification, refers to a latch tubular magnetic, which has remarkable characteristics relevant and advantageous against doorknobs or devices similar function closure, being those that incorporate an element magnetic on the latch latch making it possible for the Door open condition does not protrude from the edge of the door or front of the case or housing of the lock or latch.

It is an object of the invention to offer a latch whose structure occupies a minimum volume, that is to say compressed to the fullest but nevertheless its operation is Totally soft, quiet and effective.

Background of the invention

Currently, within the locks sector or magnetic latches, locks are known that have at least one magnetic element located inside the latch and that is attracted by a metal core located in the pocket or receiver housing incorporated into the door frame, position this one in which the closure is locked. Such is the case of the Model of Utility U-0170039 that contemplates this mechanism.

Based on the same closing system magnetic, there are other invention such as the one presented Utility Model 200601167 that claims the replacement of slip type by a magnetic closure, leaving the latch emerging in the closed door position by magnetic action of the magnet that can be placed in said latch, inside the cashier, or both. You can also cite the Utility Model no. 200601573 describing a magnetic lock and implemented with A different structure. In these cited records it is presented the common drawback that the latch tilts and being in emergency position does not save the lines of symmetry of the lock and supposes for its movement a greater complexity to the time to anticipate the mechanisms of condemnation that are incorporated.

You can also cite utility models U-200700196 by: perfected magnetic lock and the utility model U-200700257 by: latch magnetic with solidarity condemnation device, both of it Applicant of the present invention, incorporating elements Innovative in its structure, simplifying the number of pieces mobile phones and whose basic characteristics are applied in the case which concerns us with conventional tubular latches, which keep the slide latch continuously in the position of conviction, that is, in an emergency position, taking a form of triangular prism to present a ramp surface with the in order to facilitate its retraction at the time of operation of the door closing.

Description of the invention

In general, the magnetic latch Tubular object of the present invention, makes it possible, by applying the techniques of the utility models mentioned above, which conventional tubular latches can have the latch equipped with a magnetic element, be rectangular prismatic and be move linearly inside its tubular housing along the action of an oscillating arm whose other end is linked to a connecting rod driven directly by a radial projection of the nut the crank drive lock or key square.

The nut also offers a second projection radial which is operated by a spring to maintain the position of latch rest where the latch is hidden in the inside the housing.

So that at the moment that the closing of the door takes place and that simply because of this fact the latch is introduced into the pocket by magnetic action, there is a horizontal grooving at the point of attack of the oscillating arm, located in a horizontal shank integral with the latch and in which a groove is practiced whose length freely allows emergency and retraction movements of
latch.

In the condition of rest or open door, the latch remains retracted by magnetic action when stopping on a fixed metal disk provided for that purpose inside the tubular housing.

To facilitate the compression of characteristics of the invention and forming an integral part of this Descriptive report is accompanied by sheets of plans in whose figures, with an illustrative and non-limiting nature represented the following:

Brief description of the drawings

Figure 1.- It is an elevation view of the latch Tubular magnetic object of the invention, devoid of one of the parts of the box or enclosure that encloses all the elements members of the functional device, to see inside, being represented in the "closed" position.

Figure 2.- It is a view similar to Figure 1, in the starting position of the door opening when operated the square or crank key.

Figure 3.- It is a view similar to the figures above, in the rest or open door position, that is, with the locking latch away from the position confronted with the cashier or locksmith

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how the tubular magnetic latch, which The invention proposes, includes the prismatic, orthopedic latch, referenced with the number (1), which moves guided in the inside the tubular housing (2), elongated, or enclosing box the set of mechanisms or integrating elements, formed conventionally by two halves that fit and will be locked between yes, the latch (1) being emerging in the closed position at stay in the pocket or lock (3) by magnetic action to  Include a magnet inside. Figure 1 shows this closing position

The latch (1) has a horizontal and superiorly in this case shown, a rod (4) with a grooved or recessed recess (5) in which the upper end of a swing arm (6) that is operated from the opening nut (7) by a crank or wrench; conventional square no represented in the figures. The drive is transmitted by means of the connecting rod (8) arranged horizontally at the bottom of the housing (2) and provided at its ends with two holes (9) and (10) in those who play articulated and respectively the end lower swing arm (6) and radial projection (11) of the nut (7).

Reference (12) indicates the axis of rotation of the swing arm (6) that is anchored to the walls of the housing (2).

The nut (7) is assisted by the spring 13 which acts on another radial projection thereof, referenced with (14)  and that in this case it also has stop and limit functions of the turn in the counterclockwise direction of the nut when affecting the connecting rod (8).

At the beginning of the opening (position of the figure 2) by acting on the square key and turning the nut (7), the  rotation is limited when a third radial projection (15) of the same on said connecting rod (8). In this performance, the outgoing radial (11) of the nut (7) pushes the connecting rod (8) and it rotates clockwise to the swing arm (6), so that its other free end or end drag to the stem (4) to enter the latch (1) inside the housing (2) overcoming the action magnetic The door being open and therefore the latch (1) of the strike (3), when releasing the opening handle the resting position of figure 3 is recovered in which all the mobile elements, with the exception of the latch (1), recover the initial position of figure 1, because the upper end of the swing arm (6) moves freely in the grooved or recessed (5) whose length is adequate to allow this movement. Be keeps the latch (1) hidden by magnetic action on the disk metal (16) that is fixed inside the housing (2) and in which it stops.

Under these conditions, when the closing the door and the latch (1) confronts the locksmith (3), that one moves by magnetic action smoothly and accurate to return or occupy the position of figure 1, or position closing, without moving the other components. Alone involved in this slippage the greatest magnetic attraction that exerts the strike (3) on the latch (1), with respect to which provides said metal disk (16) on it.
