Abstract

A hollow body which can be fixed to the door frame houses the bolt mechanism. A lever connected to a control spindle is pivoted on the body. The spindle is surmounted by a gear which acts on a slide (4) to which is connected the locking bolt (5). The slide carrying the bolt, in the locked position, can be freely displaced longitudinally in a body housing (13) against a spring (6). The control spindle passes through an elongated opening in the direction of the slide longitudinal displacement. The spindle is surmounted at its end connection to the lever, by a part having a first portion which acts as a cam on two slide protuberances (9a,9b). A second end portion (8b) rests on a movable part (10), holding and selecting the lever gyration direction. There is a play between the control spindle end and the slide.

Description

Technical sector

The present invention relates to a closing device with a cremone mechanism for sliding doors and windows, or similar elements, of the type comprising a hollow body which houses said mechanism, which can be fixed to the frame of the door, window or element of which it is acts, on which is articulated a lever connected to a control axis, by an end portion thereof, faceted, said axis being surmounted inside by a member, such as a pinion, which acts on at least one slide, suitably guided, to which is connected, in an adjustable situation, a closing lock moving in rectilinear movement by the action of said mechanism.

State of the art

As antecedents of the invention, we can cite the patents EP-A-338621, EP-A-446566, EP-A-620343, ES-A-1023188 U and ES-A-1032136 U.

In general, in the cited documents of the prior art, there is a rigid connection between the end portion of the control shaft, in general a pinion, and the slide, which comprises a rack to which the said mesh pinion. This represents that if, in the open situation, the window or sliding door is accidentally brought towards the anchoring upright, with the lever in the closed position it can be damaged or else damage the anchoring region of the lock , or even damage the mechanism, especially in the case of large and very heavy windows or doors.

Furthermore, it is typical in structures according to the state of the art that the lever in the open situation is arranged horizontal, which, in principle, does not facilitate handling by traction to move the sliding leaf which it s 'acts.

It is also characteristic of the devices of the state of the art to offer a torque resistant to said audit. control axis, generally by inserting coaxial springs which will remain caught against a housing which surrounds the orifice for passage of the axis and combined with anti-friction washers. This solution, although it offers good characteristics, has the disadvantage of the irregularities of said spring after a certain time of use of the closure.

In the state of the art, means are also described for changing the direction of gyration of the control lever of the cremone mechanism, but these means, in addition to being expensive, impose complicated or expensive tasks for its installation.

The device of the present invention proposes to solve said drawbacks, in accordance with a differentiated structure of the cremone mechanism per se, as well as the means constituting the torque of resistance which is resistant and which limits gyration and which defines the direction of said gyration. In addition, means have been included which strengthen the connection of the hollow body which carries the cremone mechanism with the installation area at the door or window in question.

Brief description of the invention

According to the invention, the lever, in the open position, remains in an oblique orientation relative to the vertical of about 45 °, to facilitate the pulling of the leaf to be moved. This position is obtained by simply grasping the lever and pulling it with the intention of driving the leaf to be moved, with which said lever moves to a pulling position. With this position of the lever, the leaf to be moved remains free to be positioned in a desired situation, avoiding involuntary closing.

Unlike the lever, in the closed position, the interior mechanism is preserved, and in particular the sliding part carrying the lock, free, that is to say floating, pressed against a spring, to avoid accidental encounters with the elements closing or closing. This is achieved because the internal lever mechanism is created so that it can be moved without having to manipulate the joystick, and if it is moved with the joystick, the slide is moved by means of a command of the kind of a cam, which presses on said slide and not by the pinion type, as is the case of the conventional execution of said cremone mechanisms for sliding doors and windows.

In addition, the lever mechanism is identified by its state of position, by means of a small plate secured to the sliding part carrying the lock, visible through an orifice of the hollow body or carcass of the device, said small plate comprising two zones. with differentiated colors, for example red: closed and green: open, and it has been provided that, in an intermediate zone, an orifice of said small plate is opposite this orifice of the hollow body in order to pass there a tool for adjusting the position of the lock.

The hollow body which houses the mechanism has projecting walls above the edge of the device, which penetrate into a mechanized embedding in the fixing profile, by resting on its edges, with which a very rigid junction is obtained by preventing that the effort falls on the fixing screws and the conventional fixing means (lug).

The device has a plastic selector whose mounting position in the carcass changes the direction of rotation of the lever. For this, provision has been made for a bent end of this selector, which is longer, to act as a stop on the cam axis, leaving this axis to rotate only in one direction or the other, depending on its position. mounting in the carcass. This selector also comprises, in a bridge portion of the latter, liable to bending, a projection which acts in tangency against the periphery of a discoid portion of the control axis, by providing a resistant torque.

Detailed description of an implementation case

Figure 1 shows that the closure device according to the invention comprises a hollow body (1) which houses the mechanism, which can be fixed to the frame of the door, window or element in question, on is articulated a handle (2) connected to an axis (3) of control, by an end portion (3a) of the latter, with facets, said axis (3) being surmounted on the inside by a member, which acts on a slide (4), suitably guided, to which is connected, in adjustable position, a locking bolt (5) moving in rectilinear movement by the action of said mechanism. Said slide (4) carrying the lock (5), when the device is closed, it can be freely displaced, longitudinally, in a housing (13) of said body (1), against the load of a spring (6), and for this said control axis (3) passes through an elongated opening (7), in the direction of said longitudinal movement, of the slide (4). As shown in Figure 2, the control axis (3) is surmounted inside, in the distal zone at its connection to the lever (2), by a magnified configuration (8) offering on two levels a first portion (8a) which is supported by the cam office on the two protrusions (9a, 9b) of this slide (4) which flank the ends of said elongated opening (7) and a second end portion (8b) , capable of resting on a removable element (10), retaining and selecting the direction of rotation of the lever. The wall (12) which forms one of the sides of the housing (13) receiving said cremone mechanism, comprises a detent (14), on which rests one end of said spring (6), which by its other end abuts against the wall of a recess (37) of the slide (4). A socket (32) having a quadrangular end flange (33) has been provided to arrange across its axis (3) which is further arranged through a plastic washer (34) anti-friction and a metal washer (35), as well as parts (36) which form fixing lugs, associated with the ends of the hollow body (1) and urged by screws (37).

With the aim of providing a clearance between the enlarged configuration (8) of the end of the control shaft (3) and the slide (4) said metal washer (35), slightly curved, arranged coaxially to the control axis (3), has at its inner contour two straight sections (40) which correspond to planes (41, 42) on the axis (3) having lengths different from the axis (3) limits the degree of insertion of the axis (3) in the support hole of the hollow body (1), avoiding that its enlarged part (8a) can block the slide (4) during fixing from the handle (2) to the axis (3) by a fixing screw (43) which passes axially through said axis.

In FIGS. 3 to 5, it can be seen that stops (11a, 11b) have been provided in the body (1) limiting in one or the other direction of rotation of the lever (2) the amplitude of the gyration of said second portion (8b) of the enlarged end (8) of the axis (3), as well as a transverse wall (12) limiting the movement of said sliding part (4) so that in any of the directions of gyration determined by the position of the element (10), said lever (2) will describe, until arriving at the opening position of the device, an acute angle, (approximately 45 °) relative to the position initial, or closing, with a final orientation of the lever (2) inclined obliquely to the vertical, favorable for driving in the sliding direction of the door or window.

The first portion (8a) adopts the configuration of a flattened prismatic body based on a circular sector, overlapping by its apex on the axis (3) and whose diverging sides are supported, like a cam, on planes corresponding inclines of said protuberances (9a, 9b), ending in a rounded edge and on either side of one of the ends of the opening (7) of the slide (3) and in that the second portion (8b) is formed by a discoid body having a peripheral section of approximately 180 °, in diametric opposition to the area occupied by the portion (8a), with a series of ridges and depressions (25, 26) which are supported (see the Figures 3 to 5) on a projection (27) of said elastic retaining element (10), arranged as a bridge between two supports and tangent to said peripheral section, which ends in peaks (28, 29) likely to come to contact, when the axis (3) rotates, of one or other of the stops (11a, 11b) mentioned.

The element (10) is formed by an elongated member, made of plastic (for example nylon with reinforcing and hardening fillers) provided with said projection (27) and bent at its two ends (10a, 10b), in order to remain housed by nesting said bent ends (10a, 10b) in notches having the corresponding shape which surround the stops (11a, 11b), and in that one of said bent ends (10a) of the element (10) has a extension determining a stop (10c), with a concave curved inner side, limiting the direction of gyration of the lever (2) when said stop (10c) remains opposite one or other of the peaks or steps (28, 29 ) of the portion (8b).

The slide (4) has a larger and smaller central portion (4a) in which said elongated opening (7) is defined and two end sectors (4b) and (4c), having a smaller amplitude, guided in enclosures (13a) and (13b) (see FIGS. 3 to 5) delimited by pairs of walls (15, 15a, 16, 16a) parallel, longitudinal, delimiting the housing (13) and in that one of said sectors (4a ) extends into an appendage (17), perpendicular, like a cantilever peak extending outside the body (1) and which, at its end, comprises flanges forming opposite grooves (18, 18a) for the inserted mounting of the closing latch (5).

In FIGS. 7 to 9 we can appreciate the use of a small plate (19) capable of remaining applied against a peeling (20) (FIG. 1) having the complementary shape of the rear part of the appendage (17), subdivided in two sectors with differentiated colors, (19a, 19b) capable of being visible through a first orifice (21) of the body (1) a second orifice (22) existing on said small plate (19), for passage through said two orifices (21, 22), coaligned in a certain position of rotation of the lever (2), with a tool for controlling an element (23) such as a screw inserted in a borehole (24) threaded to its inside, axial to the appendix (17) for fixing the latch (5) in an appropriate situation.

The hollow body (1) has at its central region and near its two ends a series of pairs of walls, including said (15, 15a, 16, 16a), the outer edge of which exceeds the contour of said body (1) , the profiles of which fit into an opening in the window or door frame where the body (1) must be fixed, supported on its edges as shown in FIG. 6.

There is also provision for connection to the handle of a lock cylinder (not shown), its movement then being possible only if one has released said closure before with the corresponding key.
