Description

The present invention relates to a locking device in position

  open for joinery comprising a sliding leaf and its receiving chamber; the present invention further relates to a carpentry with an opening

  slider and its receiving box comprising such a device.

  As is known, sliding windows can be used in correspondence of partition walls between two rooms and have a support frame, generally of rectangular shape, consisting of an amount of development substantially transverse to the direction of movement of the opening, a cross member engaged on the upright and perpendicular to the latter and a box receiving the opening in the open position.

  In particular, the receiving box is engaged on the cross member of the opposite portion relative to the amount and has a conformation substantially identical to the opening to contain. The opening defined between the box and the vertical upright constitutes the passage that the sliding leaf must conceal, or keep free.

  The receiving box, which can be inserted inside a partition wall so as to be invisible, can be constituted by a box-shaped body having a passage opening of the respective opening oriented towards the upright. Such a box-shaped body can be made of metal, and this is the case of the majority of woodwork currently on the market, or non-metallic material. Such a box-shaped body can also be reduced simply to an open frame, possibly coated.

  An essential element of the receiving box is constituted by the fact that a bottom portion acts as an abutment surface towards which the opening moves when it tends to open, and such a bottom portion can be defined directly by a wall or an element attached to it. For this purpose, the receiving box could consist of even a simple recess formed in the wall to accommodate the opening. In the technical field in object, one feels the requirement to be able to removably lock the sliding leaf in the open position.

  The object of the present invention is to provide a locking device in the open position, for joinery with sliding leaf and its receiving box, allowing instantaneous blocking and practical opening. Another no less important object of the present invention is to provide a locking device that allows easy installation on commercial common joinery with sliding door and receiving box having a metal bottom or at least partially metallic, regardless of geometry and the form of special accessory devices such as handles.

  Another object of the present invention is to provide a locking device without projecting elements of the form of the opening at least in a plane substantially transverse to its direction of travel.

  These and other objects, which will appear more clearly in the description which follows, are achieved, in accordance with the present invention, by a locking device in the open position and by a joinery with at least one sliding leaf and its receiving chamber.

  The invention is illustrated in more detail below with the aid of the drawings, which represent an embodiment thereof by way of non-limiting example: FIG. 1 illustrates a perspective view, partially exploded, of a device according to the invention; - Figure 2 shows, in side view, a device according to the invention; FIG. 3 shows an exploded perspective view of an alternative constructive solution; - Figure 4 shows the device shown in the previous figure in a particular operational configuration; - Figure 5 shows a front view of a carpentry including the invention; - Figures 6, 7 and 8 show three constructive details of the previous carpentry.

  Referring to Figures 2 and 4, there is indicated by 10 a blocking device in the open position for joinery with at least one sliding leaf and its receiving box.

  Such a device comprises at least a first element 11 which in turn comprises first locking means 111, and this first element 11 is applicable to a sliding door 5 of a joinery 1 in correspondence of a first edge 51 of the opening 5, the first edge 51 is inside a box 6 for receiving the sliding door 5. The first edge 51 also has a development substantially transverse to a direction 8 of movement of the opening 5 itself. Such a device 10 further comprises at least one second element 12 comprising second locking means 121 and is applicable in correspondence of a bottom portion 61 of the receiving chamber 6 disposed opposite its first edge 51. The first and second locking means 111, 121 are applicable on joinery 1, and considered together, comprise at least one magnetic field generator and parts sensitive to the action of the magnetic field. The magnetic generator and the parts sensitive to the action of the magnetic field are intended to interact magnetically with one another to enable the opening 5 to be locked in the fully open configuration.

  In a first preferred solution, the magnetic field generator comprises a first magnet 2, forming part of the first locking means 111 and the magnetic field sensitive portions comprise at least one first magnetic field sensitive component forming part of the second 121 locking means. In such a configuration, the second locking means 121 and the second element 12 are made by means of the first magnetic field sensitive component.

  Such a first component sensitive to the magnetic field may consist for example of metal elements. Such a first component sensitive to the magnetic field, preferably and advantageously, can be integrated in a single body with the bottom 61 of the receiving box 6. The bottom 61 of the receiving box 6, if it is metallic, can therefore be identified as this first component sensitive to the magnetic field. If in a second solution the receiving box 6 was not made of a material sensitive to magnetic fields, such a magnetic field sensitive component can be constructed from an insert, for example a metal insert, stably connected to the box. 6 and provided with such magnetic interaction properties. Such an insert can be accommodated in a suitable conformation of the bottom 61 of the receiving chamber 6.

  The device 10 in object can therefore be applied even on existing joineries 1 or reception boxes 6 not originally predisposed to the application of the latter; it is sufficient that the bottom 61 of the receiving chamber 6 is at least partly metal as in the case of most of the joinery in the trade. In this case, even if the joineries 1 are already installed, one would intervene exclusively, possibly by removing it, on the sliding door 5 and therefore in a practical way without having to intervene on the bottom 61 of the receiving box 6. The bottom 61 is indeed difficult to access from an operator.

  In an alternative configuration, the magnetic field generator comprises a second magnet 21, forming part of second locking means 121; the parts sensitive to the action of the magnetic field comprise at least one second component sensitive to the magnetic field forming part of the first blocking means 111. In this case, the first locking means 111 may consist of a single metal element or a magnet with the polarities oriented so that the two magnets do not repel each other. The technical characteristics described for the first magnet 2 can in this case be applied to the second magnet 21.

  Among all the solutions described, the first solution has the big advantage that the majority of the standard woodwork 1 currently in the trade have a metal receiving box 6 and therefore the device 10 in object could be directly applied to these windows 1, in leaving unaltered the productive process of the latter.

  Still in the first configuration, the first element 11 comprises a housing 112 protecting the first magnet 2 which surrounds and protects the latter from shocks; indeed, the magnets are particularly fragile and there is the risk of rupture.

  Outside the housing 112 protector protrusions 4 are sensitive to the magnetic field. The latter may for example be made of metallic or ferromagnetic material, and through these pass the lines of force of the magnetic field. At the end of the opening stroke, the opening 5 comes into contact, by striking it, with the bottom portion 61 of the receiving chamber 6. In order not to damage the magnet 2, are advantageously present inside the housing 112 protecting first shock damping means interposed between the first magnet 2 and the projections 4 sensitive to the magnetic field.

  The first element 11 comprises second damping means 31 completing the action of the first damping means. These second damping means 31 consist, for example, of rubber pads or other technical equivalents which absorb the energy that accompanies the impact.

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

  Alternatively, in a second configuration illustrated in FIGS. 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 opening 5. The rod 7 and the support 113 can be connected by means of an axis 114 and the rod 7 has in correspondence of its first end 71 the first locking means 111 and in correspondence with its second end 72 the second damping means 31. In correspondence of the second end 72 of the rod 7 are further arranged second elastic means 115 having a first end connected to the second end 72 and a second end secured to the support 113. Such second elastic means 115 may for example consist of of a helical spring as illustrated in FIG.

  As illustrated in FIGS. 1 and 3, the device could advantageously comprise spacers 9 of predefined thickness that can be interposed between the first element 11 and the first edge 51 of the opening 5. In this way, it is possible to compensate for any variations, in the configuration of complete opening, the distance between the first edge 51 of the opening 5 and the bottom portion 61 of the receiving chamber 6. Such variations may for example be determined by the use of handles having a size such that they strike the wall during the opening stroke of the opening 5, by preventing reaching the end-of-travel configuration provided for in FIG. sizing.

  By suitably thickening the first element 11, the latter is thus allowed to come into contact with the second element 12, thus blocking, thanks to the action exerted by the magnetic field, the opening element 5. From the moment when the most of the joineries 1 present on the market includes a metal receiving box 6, the addition of the spacers 9 can be done in the last phase of the assembly, in a practical and fast way, nevertheless allowing the mass production as well of the opening 5 of the receiving box 6 and the device 10.

  In Figure 5 is shown a joinery 1 with at least one sliding door, of the type comprising at least a portion of the receiving chamber 6 responsive to the action of magnetic fields. The joineries 1 have a support frame, generally rectangular in shape, consisting of a post 63 developed substantially transverse to the direction 8 of movement of the opening 5, a cross member 64 engaged on the upright 63 and perpendicular to the latter and a box 6 receiving the opening 5 in the open position. The receiving box 6 can be inserted into a recess and the opening 5 is movable along the longitudinal development of the crossmember 64 between a fully open position, in which it abuts against a bottom portion 61 of the box 6 of internal receiving at the niche, and a closed position in which it is remote from the bottom portion 61. Such a carpentry comprises the locking device 10 opening, as described above. The device 10 can be advantageously applied not only to sliding doors, but also to other joineries 1 such as for example windows or hatches formed in the ceiling, the floor or the walls.

  Such joineries advantageously comprise means 13 for automatically returning the opening 5 from the open position to the closed position.

  Alternatively, closing of the latter can occur manually.

  The automatic return means 13 may advantageously comprise at least one linear elastic element 131 associated with the sliding opening 5, said elastic element 131 having an axial development substantially forming part of the plane comprising the opening 5 and deformable linearly along its own axial development. Such a linear elastic element is advantageously arranged near the first edge 51 of the opening 5 in which is connected the first element 11 of the device 10. Such return means 13 are described in detail in the Italian patent application RN2004A000014 and comprise at least one connecting member 132, having a first end associated with the elastic element 131 and a second end, disposed on the crosspiece 64 in the vicinity of a post 63 substantially transverse to the direction of movement of the opening 5 which in the closed position serves as a stop for the latter. This elastic element 131 may be constituted for example by a helical spring. The connecting member 132 further has a return wheel, preferably disposed in an angular portion of the opening 5. A member 135 for regulating the degree of pre-tension of the elastic element 131 is illustrated in Figure 6. By regulating the pre-tension, it is advantageous to adjust the closing speed of the doors 5, also taking into account the different weight of the latter. Other particular solutions of such automatic return means 13 may be provided. For example, in a second alternative configuration not illustrated, a counterweight made in the post 63 is connected to the opening 5. Said counterweight is raised when the opening 5 is open and the return of the opening 5 occurs through the driving action induced by the force of gravity exerted on the counterweight.

  To curb the movement of the opening 5 between the open position and the closed position, the joinery 1 advantageously comprises means 14 for slowing down.

  The slowing means 14 advantageously comprise a guide along the direction 8 of movement of the opening 5 and have at least one rack 151 and at least one pivoting toothed wheel 152. The latter pivots about a transverse axis to the direction 8 of movement of the opening 5 and meshes with a plurality of teeth 153 of the rack 151. The toothed wheel 152 also has a friction portion, not shown or described since of known type and normally used in the specific technical sector. The friction portion is able to brake the rotation of the gear 152 in a single direction of rotation, corresponding to the movement of the opening 5 from the open position to the closed position. In this way, the opening 5 closes gently, avoiding that it beats.

  The operation of the variant of the device 10 illustrated in Figures 1 and 2 is as follows: when the sliding leaf 5 reaches the fully open position, the projections 4 sensitive to the magnetic field come into contact with the bottom portion 61 of the box 6 receiving and the first damping means attenuate the shock. Successively, even the second damping means 31 meet the bottom portion 61 of the receiving box 6 by absorbing a portion of the impact energy. Thanks to the action of the magnetic field between the first and the second element 11, 12, the opening 5 and the receiving box 6 will be integral and it will be necessary to unlock them to apply from the user a force sufficiently intense in the direction of the closure of the joinery 1.

  In the case of the variant illustrated in FIGS. 3 and 4, when the opening opening 5 comes to the end of travel, the second damping means 31 first come into contact with the bottom portion 61 of the reception box 6 and, if the force applied is insufficient to overcome the contrasting action given by the second elastic means, the device 10 will not block the opening 5. Alternatively, if the force is sufficient, the rod 7 will be actuated and , by pivoting about the axis 114, will carry the projections 4 sensitive to the magnetic field in contact with the second locking means 121 relative to the bottom portion 61 of the receiving box 6, blocking the device 10. In this way are prevented unintentional blockages since is necessary adequate pressure to operate the device 10. The unlocking of the opening 5 occurs identically to what has been described in the variant of the previous case.

  The invention has important advantages.

  First, it allows instant blocking and unblocking, as well as great simplicity and functionality.

  An advantage also very important is that the device of the invention makes compatible, with an extremely fast and convenient mounting operation, the opening and the receiving boxes 6, regardless of footprint and the mounting position of handles or other accessory items. Another advantage lies in the fact that the device can be suitably used with joineries 1 with reception boxes 6 made of metallic material, the latter being precisely those having the greatest diffusion on the market.

  In addition, advantageously, the absence in the locking device of salient elements in a direction transverse to the movement of the opening, besides constituting an aesthetic value, improves the functionality since there is no means that could hinder the movement of the opening.

  The invention thus conceived is susceptible to numerous modifications and variations, all of which are part of the field of the inventive concept which characterizes it.

  In addition, all the details are replaceable by other technically equivalent elements.

  In practice, all the materials used, as well as the dimensions, can be of any kind, according to the requirements.
