Description

Locking device for enclosures of slide.

Object of the invention

The present invention relates to a locking device for sliding enclosures, of the type of those comprising a support piece intended to be fixed in one of the uprights of the inner sliding leaf and a pin intended to be introduced, through the support piece, into defined holes in the facing pillars of the blades sliding, setting the lock of said sheets in position of closing.

Background of the invention

At present, the sliding leaf enclosures mounted on a fixed frame, arranging the sliding blades at opposite ends of some latches for retention in the closed position with respect to corresponding amount of the fixed frame.

These enclosures present a problem of important security, since the latches can be unlocked easily, slightly raising one of the leaves, to access inside the room from the outside.

To avoid this security problem, there are blocking devices comprising a support piece which is fixed on the amount of one of the leaves and a pin removable that is introduced, through a passage of the mentioned support piece, in holes defined in the uprights of the two sheets and that are arranged facing each other in the closed position of the enclosure, preventing said pin from moving relative of the two sheets and consequently the opening of the enclosure.

The passage of the support and pin piece They have two threaded sections for coupling and fixing in the position of use of the pin.

One of the problems with this device is that when the pin is removed to unlock the enclosure, said pin is loose and separated from the support piece, being able to get lost, making the device inoperative.

Another drawback of this device is that the placement and removal of the pin are uncomfortable since that you must position the pin correctly and give it several turns to get its screwed on the base piece. From elsewhere the threads of the support piece and the pin are subjected to a  significant wear and may be impaired by attempts to move the locked sliding sheets and by the continuous ones couplings and decoupling.

Description of the invention

The locking device for enclosures of slide, object of this invention, being of the type of which they comprise a support piece intended to be fixed in a hole intern defined in one of the uprights of the sliding leaf interior and provided with a passage for the movable mounting of a locking pin, provided with a rear drive knob and that sets the sliding leaf lock in position of closing when being introduced in a trade defined in the amount facing the outer sliding leaf; present some technical characteristics intended to simplify its use and to configure a compact mechanism, in which the different parts they remain related to each other regardless of the pin is in an operational position or in a position inoperative.

For this, and according to the invention, the pin laterally presents a longitudinal groove in which find a cursor attached to the support piece and that limits the longitudinal displacement of the pin between a inoperative rear position, in which said pin releases the external sliding leaf allowing the opening of the enclosure, and a previous operative position in which the pin is housed in the hole in front of the outer sliding leaf preventing its relative displacement and blocking both sliding blades in the closing position

The limitation of the pin travel by the cursor contact against opposite ends of the slot longitudinal of the pin, ensures that said pin remains permanently mounted on the support piece, so prevents its loss.

According to the invention the groove Longitudinal is extended by its anterior end and in the direction lateral in a transverse section for the accommodation of the cursor and the retention of the pin in the inoperative rear position of said Barrette.

This feature allows the pin to stay stably in the back position inoperative.

This device additionally comprises a spring mounted around the pin and acting with the ends opposite against the front end of the support piece and against a pin stop; causing said spring the displacement automatic pin to the previous operating position when the cursor is released from the transverse section of the slot longitudinal, by turning the pin of an amplitude equivalent to the length of said cross section.

To place the pin in the position of lock or unlock just enter or remove the cursor of the transverse section of the groove, operation that is performed by a lateral rotation of the pin, of small amplitude, which It is more comfortable than the screw fixing used in known devices

In one embodiment of the invention the cursor It consists of a screw attached to a side hole Threading of the support piece.

According to the invention, the pin stop, and over which acts the spring, is formed by a stepped surrounding projection of the front end of said pin.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows an elevation view of the device of the invention installed of a leaf enclosure Sliding

- Figure 2 shows a longitudinal section Of the device.

- Figure 3 shows a longitudinal section of the device by a plane perpendicular to the section plane of the previous figure.

- Figure 4 shows a sectioned detail of the device mounted on sliding blades, with the pin in the operating position lock.

- Figure 5 shows a view similar to the above, with the pin in the inoperative position of unlock

Preferred Embodiment of the Invention

As can be seen in the figures referenced the locking device comprises a piece of bracket (1) defining a tubular passage (12) for mounting movable of a pin (2) blocking the two sliding blades (3a, 3b) that have two holes (31a, 31b) in the uprights intended to meet in the closed position of the enclosure.

The mentioned support piece (1) is fixed in correspondence with the hole (31a) of the sliding leaf (3a) inside by means of screws mounted through the holes (eleven).

The pin (2) of cylindrical configuration, at its rear end it has a drive knob (5) and, laterally, a longitudinal groove (21) that extends laterally by its anterior end a transverse section (22). To its  once the support piece (1) has a hole (13) laterally threaded on which a cursor (4) is mounted, represented by a screw, whose end is arranged inside the passage (12) and housed in said longitudinal groove (21) of the pin, limiting its longitudinal displacement between a position previous operation and an inoperative rear position. Around pin (2) is mounted a spring (6) that acts with the opposite ends against the front end of the support piece (1) and against a stop formed by a perimeter step (23) of said pin (2). This spring (6) tends to hold the pin (2) in the previous operative position.

When the cursor (4) is housed in the longitudinal groove (21) the pin (2) is held in position previous operation represented in figures 3 and 4, staying in the hole (31b) of the outer sliding leaf (3b) and blocking the two sliding blades (3a, 3b) in the closed position.

To unlock the sliding blades (3a, 3b) just pull the pin (2) back, compressing the spring (6) until the cursor (4) abuts the end anterior of the longitudinal groove (21), and then turn the pin to the extent necessary to get the accommodation of the cursor (4) in the transverse section (22) of the longitudinal groove (twenty-one); This ensures stable retention of the pin in the inoperative rear position represented in the figure 5.

In this inoperative posterior position, the pin (2) releases the outer sliding leaf (3b) by unlocking the closing position of the enclosure.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
