Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The invention consists of a latch and a sliding door fitting, which fitting has a handle integrated with an operating slide that cooperates with the operating element of the latch via a connecting element. The present invention relates to a locking mechanism for a sliding door having an inner panel and an outer panel with a safety block that cooperates with an operating slider via a power transmission piece.

[Conventional technology and problems]

Consists of a latch and a sliding door fitting, the former fitting comprising an inner plate with a handle integrated with an operating slider that cooperates with the operating element of the latch via a connecting element, and a handle that cooperates with the operating slider via a power transmission piece. A locking mechanism for a sliding door having an outer panel with a safety block is already known from US Pat. No. 3,368,374.

However, this known mechanism cannot be applied to sliding doors of any thickness, since the coupling of the latch operating element to the operating slider and the safety block to the operating slider respectively limits the thickness range of the sliding door.

An object of the present invention is to propose a sliding door locking mechanism that can be easily adapted to sliding doors of a wide range of thicknesses.

[Means for solving problems]

The invention therefore consists of a latch and a sliding door fitting, which has an inner plate with an operating slide and an integral handle that cooperates with the operating element of the latch via a connecting element, and which is actuated via a power transmission piece. A sliding door locking mechanism having a slider and an outer panel with a cooperating safety block is proposed, characterized in that the latch operating element and the operating slider cooperating with the safety block are reversible.

With this configuration, depending on the thickness of the sliding door,
A plane facing the latch, i.e. an operating element plane containing the coupling element cooperating with the latch operating element, and a plane facing the safety block, precisely the operating slide plane containing the transverse slot cooperating with the power transmission piece of the safety block. A specific operating slider can be provided taking into account the positional deviation that exists between.

Since the latch placed approximately in the center of the thickness of the sliding door changes by 1/2 of the change in thickness, the amount of positional deviation will change by approximately 1/2 of the change in the thickness of the sliding door, and the latch will change by approximately 1/2 of the change in thickness of the sliding door. The safety block is displaced by an amount equal to the change in sliding door thickness.

If the handle is integrated with the operating slide by means of at least one elastic fastening element, the implementation of an effective operating slide is made very easy.

In a preferred embodiment of the invention, the operating slide has on each side a plane facing the latch and a plane facing the safety block, which allows the operating slide to be reversed. Therefore, the same mechanism can be used for sliding doors of different thicknesses. That is, the operating slider can act on one side of a sliding door of a predetermined thickness, and can be reversed and act on the other side of a sliding door of a different thickness.

The reversible operation slider has at least one of its surfaces having a misalignment between the plane facing the latch and the plane facing the safety block, and the amount of misalignment between the plane facing the latch and the plane facing the safety block is equal to the amount of misalignment between the plane facing the latch and the plane facing the safety block. Preferably, the occlusion depth is equal to the difference between the minimum occlusion depth and the maximum occlusion depth of the coupling element and/or the power transmission piece of the safety block.

According to the invention, the handle is integrated with the operating slider by means of at least one screw whose head connects the operating slider and the latch.

In another embodiment, the handle is integrated with the operating slider by two screws, one having a head associated with one side of the operating slide and the other having a head associated with the other side of the operating slide. .

With this configuration, in order to adapt the locking mechanism to sliding doors of other thicknesses, it is only necessary to replace the screw when reversing the operating slider.
