Description

Locking device in opening position for lattices with sliding leaf and box of capacity.

The present invention relates to a locking device in opening position for lattices with sliding sheet and corresponding box; the present invention also refers to a lattice with a sliding sheet and corresponding box that includes such a device.

It is known in the state of the art the Utility Model No. U0261916 "Lattice window with adjustable opening", from 1981, on behalf of Mr. Joaquín GONZALEZ OLMO, refers to a lattice window with adjustable opening, whose two amounts they are U-section profiles, and one of them houses the control mechanism, characterized in that said control mechanism consists essentially of a lever that appears and can exit to the outside through a groove made in a wing of the profile, placing its button in front upper, when it turns on its lower support point, next to which it has an extension that is staggered to reach the level of a brace and articulate on it with a riveted pin, and because said support point consists of a disk of material plastic that is housed with a certain adjustment inside a circular hole made in the bottom wall of the profile turning smoothly, which plastic disc advantageously has a thickness somewhat greater than the thickness of the wall of the profile and to one of its faces the aforementioned lever is attached while to the other the corresponding part of a glass support is attached, there being a pair of rivets that crosses the three pieces and unifies them in the turn, for which the axis is its own
disk.

The Model of Utility No. 200301764 (1055338) "Lattice with fixed louvers perfected ", of the year 2003, in the name of ASTRON INVERSIONES, S.L., which refers to a perfected fixed louver lattice, of the type that comprises a plurality of slats substantially parallels arranged between at least two stringers in situation transverse for fastening as a shader, remover, parasol or similar for a construction, characterized in that It comprises at least one guide stringer on each of the stringers existing in said guide rail an anchor support of each plank fixed by friction to said guide beam; and why the lama is held on the support by clipping or similar.

As you know, sliding lattices can be  used in correspondence of dividing walls between two openings and have a support frame, usually in shape rectangular, consisting of an extension with extension substantially transverse with respect to the direction of leaf movement, a crossbar linked to the upright and perpendicular to it and a sheet-fit box in position opening

In particular, the box is linked to the crossbar of the opposite part with respect to the amount and has a conformation substantially identical to the sheet that must contain. The defined opening between the box and the upright vertical constitutes the step that the sliding sheet must occlude, or set free.

The box, which can be placed inside  of a dividing wall so that it is hidden, it can be constituted by a body type box with a passage opening of the respective sheet towards the upright. Such body Box type can be made of both metallic material, it is the case of most of the lattices that are currently in the market, as of non-metallic material. Such a box type body too it can simply be an open frame, eventually coated.

An essential element of the box is that  there is a bottom portion that acts as a stop surface towards where the blade moves when it opens and such a bottom portion can be defined directly by a wall or an element placed about it. In that sense the box could also be  simply a vain obtained in the wall suitable to house the sheet.

In the technical sector under review it is attributed great importance to the need to lock the sheet sliding, removably, in its opening position.

The objective of the present invention is to make available a locking device in the position of opening, for lattices with sliding leaf and corresponding box of capacity, which allows the easy and instantaneous blocking of the sheet. Another, no less important, objective of the present invention is to make available a locking device that allows be easily installed in common commercial lattices with sliding leaf and with a box that has a metallic bottom or at least partially metallic, regardless of geometry and profiling of special accessory devices, which For example handles.

Another objective of the present invention is that of make available a locking device without elements protruding contour of the sheet at least in one plane substantially transverse to its direction of movement.

These goals and still others, which will still be set more evident in the course of the description that follows, it they achieve, according to the present invention, by means of a device lock in opening position and lattice with at least one leaf sliding and corresponding box with features structural and functional according to the claims independents that are ahead, whose other forms of execution can be identified in the annexes and corresponding dependent claims.

Below is the description, with greater details of the invention supported by the attached drawings, which represent a purely exemplifying embodiment and not limiting:

With reference to figures 2 and 4, with the numeral 10 a blocking device has been indicated in its position opening for blinds with at least one sliding sheet and corresponding box.

Such device comprises at least a first element (11) which in turn comprises first means (111) of blocking, and such first element (11) can be arranged on a sliding sheet (5) of a lattice (1), specifically on the first edge (51) of said sheet (5), also maintaining the mentioned first edge (51) inside a box (6) for accommodating the  respective sliding sheet (5). Such device (10) in addition comprises at least a second element (12) comprising seconds blocking means (121) and can be applied in correspondence of a bottom portion (61) of the box (6) fitted with facing the first edge (51). The first and second means (111 and 121) blocking, applicable to lattice (1), and considered in its together, they comprise at least one magnetic field generator and parts sensitive to the action of the magnetic field. Generator magnetic field and parts sensitive to field action magnetic are intended to interact magnetically with each other to enable blocking of the sheet (5) in the configuration of total opening

In a first preferred solution the generator magnetic field comprises a first magnet (2), which is part of the first blocking means (111), and the parts sensitive to the magnetic field action comprise at least a first magnetic field sensitive component that is part of the second means (121) of blocking. In that configuration, the second locking means (121) and the second element (12) is performed using the first field sensitive component magnetic.

Such first field sensitive component magnetic can be constituted, for example, by elements metallic Such a first component sensitive to the magnetic field, advantageously and preferably, it can be integrated into a single body with the bottom (61) of the box (6). The background (61) of the box (6) fitted if it were metallic, then it can be identified with such a first component sensitive to the magnetic field. In the case that, in a second solution, the box (6) does not fit It is made of material sensitive to magnetic fields, such magnetic field sensitive component may be constituted by a complement, for example metallic, stably connected to the box (6) and provided with such magnetic interaction properties. Such complement can be housed in a profile for this purpose. bottom (61) of the box (6).

The device (10) in question, therefore, It can also be applied to existing blinds (1) or boxes (6) of room that have not been originally predisposed to your application; indeed, it would be enough that the fund (61) of the box (6) fit outside, at least in part, metallic as in the case of the most of the lattices (1) that are in trade. In that Even if the lattices (1) are already in place, would intervene exclusively, if necessary by disassembling it, in the sliding sheet (5) and, therefore, without difficulties and without having to intervene in the bottom (61) of the box (6) of capacity. The bottom (61), in effect, is difficult for the operator to access.

In an alternative configuration the generator  magnetic field comprises a second magnet (21), which is part of the second means (121) of blocking; the parts sensitive to magnetic field action comprise at least one second magnetic field sensitive component that is part of the first means (111) of blocking. In that case the first media (111) lock may consist of a simple element metallic or by a magnet with its polarities oriented so such that the two magnets do not reject each other. The characteristics techniques described for the first magnet (2) can be applied, where appropriate, to the second magnet (21).

Of all the solutions described, the first solution presents the great advantage related to the fact that the most of the lattices (1) standards that are currently in the store has the metal box (6) and, therefore, the device (10) in question could be applied directly to such lattices (1), leaving its productive process unchanged.

Always in the first configuration, the first element (11) comprises a protective wrapper (112) of the first magnet (2) that envelops and shields the latter against shocks; indeed, magnets such as calamitas are very fragile and, for consequently, there is a risk of them breaking.

Outside the wrapper (112) protector is extend protrusions (4) sensitive to the magnetic field. The they can be, for example, of metallic material or ferromagnetic and through them pass the lines of force of the magnetic field. At the end of the opening race, the sheet (5) comes into contact, colliding, with the bottom portion (61) of the box (6) fit. In order not to damage the magnet (2) advantageously inside the protective wrapper (112) there are first shock absorbing means interspersed between the first magnet (2) and protrusions (4) sensitive to the magnetic field.

The first element (11) comprises seconds damping means (31) that contribute to the action of the First damping means. Such second means (31) of cushioning, for example, are constituted by pads of rubber or other equivalent technical elements that absorb the shock energy.

The first element (11) comprises a support (113), applicable to the first edge (51), to which they are connected directly both the first blocking means (111) and the second means (31) of damping.

Alternatively, in a second configuration shown in figures 3 and 4, the first element (11) comprises a tilting rod (7) and a support (113) that can be connected to the first edge (51) of the sheet (5). The rod (7) and the support (113) are connected by a bolt (114), the rod (7) presenting in correspondence of its first limb (71) the first means (111) of blocking and in correspondence of its second tip (72) the second means (31) of damping. In correspondence of the second end (72) of the rod (7), in addition, second elastic means (115) are placed which have a first end connected to the second extremity (72) and a second end integral to the support (113). Such second means (115) elastics, for example, may be constituted by a helical spring as can be seen in figure 3.

As can be seen in Figures 1 and 3, of advantageously the device could comprise elements (9) predefined and intercalable thickness separators between the first element (11) and the first edge (51) of the sheet (5). In this way possible variations can be compensated in the configuration of total opening, of the distance between the first edge (51) of the sheet (5) and the bottom portion (61) of the box (6). Such variations, for example, could be determined by employment of handles with dimensions that make them collide with the wall during the opening of the leaf (5), preventing reach the end of career configuration planned in the sizing. Therefore, timely giving a greater thickness to the first element (11), the latter is allowed to enter in contact with the second element (12) thus blocking, thanks to the action exerted by the magnetic field, the sheet (5). Having note that most of the lattices (1) present in the market comprises a box (6) of fit, of metallic material, the the last phase there is the possibility of adding elements (9) separators, quickly and without difficulties, allowing, also, that a mass production of others can be carried out parts such as the sheet (5), the box (6) or the device (10).

Figure 5 shows a lattice (1) with at  at least one sliding sheet (5), of the type comprising at least one portion of the box (6) of field-sensitive space magnetic The lattices (1) have a support frame, generally rectangular in shape, consisting of an upright (63) with extension substantially transverse to the direction (8) of movement of the leaf (5), a crossbar (64) linked to the upright (63) and perpendicular to it and a box (6) of sheet fit (5) in the open position. The box (6) can be placed recessed and the sheet (5) is mobile along the longitudinal extension of the crossbar (64) between a position of total opening, in which it hits a bottom portion (61) of the box (6) fitted inside the housing, and a position of closure, in which it is far from the bottom portion (61). Such Lattice (1) includes the opening lock device (10), such  as described above. Advantageously, the device (10) can be applied not only to sliding doors, but also to other lattices (1), which, for example, windows or ceiling, floor or wall hatches.

Advantageously, such lattice (1) comprises automatic means (13) for attracting the leaf (5) of the position from opening to closing position. Alternatively the closure of It is produced manually.

Advantageously, automatic means (13)  of attraction may comprise at least one elastic element (131) linear associated to the sliding sheet (5), said element (131) linear elastic having an axial extension substantially in the sheet layout plane (5) and being deformable linearly along its own axial extension. By way of advantageously, such a linear elastic element is arranged near the first edge (51) of the sheet (5) where the first is connected element (11) of the device (10). Such means (13) of attraction are described in details in the invention patent application Italian RN2004A000014 and include at least one organ (132) of connection, which has a first limb associated with the element {131) elastic and a second limb, located in the crossbar (64) near an upright (63) substantially transverse to the direction of movement of the blade (5), which in the closed position acts as the top of the latter. Such elastic element (131) can be constituted, for example, by a coil spring. The organ (132) connection also features a transmission roller, preferably arranged in an angular portion of the sheet (5). In Figure 6 shows an organ (135) for regulating the degree of prestressing of the elastic element (131). Advantageously, by adjusting the prestressing, the closing speed of the sheets (5), also taking into account the different weight from the same. Other special solutions of such may be provided. automatic means (13) of attraction. For example, in a second alternative configuration, not illustrated, sheet (5) is connected to a counterweight made within the amount (63). Saying counterweight is lifted at the moment that the leaf (5) opens, with what which the attraction of the leaf (5) is produced thanks to the action of drag induced by the force of gravity exerted on the counterweight.

To stop the movement of the blade (5) between the opening position and the closing position the lattice (1) of Advantageously it includes braking means (14).

The braking means (14) advantageously include a guide along the direction (8) of movement of the sheet (5) and have at least one zipper (151) and at least a rotating gearwheel (152). The latter revolves around a axis transverse to the direction (8) of movement of the blade (5) and gears with a plurality of teeth (153) of the rack (151). The toothed wheel (152) also has a friction portion, not illustrated or described since it is of known type and commonly used in the specific technical sector. Friction portion It is suitable for slowing the rotation of the cogwheel (152) only in a direction of rotation, corresponding to the movement of the blade (5) from the opening to the closing position. In this way the sheet (5) closes gently, without hitting.

The operation of the device variant  (10) shown in Figures 1 and 2 is as follows: when the sheet (5) Sliding reaches the total opening position protrusions (4) sensitive to the magnetic field come into contact with the bottom portion (61) of the box (6) and the First damping means soften the shock. Later  also the second damping means (31) bump the portion (61) at the bottom of the box (6) accommodating absorbing part of the shock energy. Thanks to the action of the magnetic field between the first and the second element (11 and 12), the sheet (5) and the box (6) there will be solidarity; to unlock them will be it is necessary for the user to apply a sufficiently strong force in the closing direction of the lattice (1).

In the case of the variant illustrated in the Figures 3 and 4, when the leaf (5), at its opening, reaches the end running, the second damping means (31) first come into contact with the bottom portion (61) of the box (6) of fit and, in the case that the force applied is not sufficient to beat the contrast action exerted by the second means (115) elastic, the device (10) will not block the sheet (5). Alternatively, in case the force is sufficient, it will operate the lever (7), thereby rotating around the bolt (114) will carry the protrusions (4) sensitive to the magnetic field in contact with the second locking means (121) corresponding to the bottom portion (61) of the box (6) of fit, blocking the device (10). In this way they are prevented unwanted locks since to activate the device (10) It is necessary to exert adequate pressure. The unlocking of the sheet (5) occurs analogously to what is described in the variant of the last case.

The invention achieves important advantages.

First of all it allows locking and unlocking Instant, in addition to high simplicity and functionality.

An equally important advantage is constituted by the fact that the device of the invention returns compatible, with extremely fast assembly intervention and easy, sheets and corresponding boxes, regardless of dimensions and mounting position of handles or other accessory elements. Another advantage is that the device can be conveniently used with lattices (1) with boxes (6) fitted made of metallic material, the latter being just the most widespread in the market.

Advantageously, moreover, the absence in the locking device for projecting elements in the direction transverse to the movement of the leaf, apart from its aesthetic value, it allows to improve the functionality without having means that could hinder the movement of the blade.

The invention conceived in this way is susceptible of numerous variants and modifications, all within of the scope of the inventive concept that characterizes it.

In addition, all the details can be replaced by other technically equivalent elements.

In practice, all the materials used, as well as the dimensions, may be any, depending on the needs.
