Description

Insurance return device.

The present invention relates to the field of Construction hardware.

The invention relates in particular to a insurance return device according to the preamble of the claim 1.

There are already insurance return devices for this type. For this purpose, to better understand this state of technique, we will refer to figures 1 and 2 of the drawings attachments, in which:

Figure 1 is a schematic and sectional view. of the front uprights of two leaves A, B of a window, an A of which it comes in coating of the second B;

figure 2 represents these same uprights displaced relative to each other, the handle being disassembled here of control.

In fact, this state of the art represented in these figures 1 and 2 and which is described in detail below corresponds, in particular, to the document DE-U-91 03 676.

Thus, as can be seen in figures 1 and 2, the frame corresponding to sheet A includes a band of coating C that comes in apply against a support flange D of the other sheet B. In addition, this frame of the sheet in coating A receives, in the renvalso of its front stile, a hardware of lock E that is housed in a recess slot F provided for such end

You can also see that, on the internal side, the cover strip C of this front sheet A receives an inner frame G, in the form of a finishing profile that confers a certain symmetry to the set, in addition to this frame G closes the renvalso H (figure 1) existing between the edges of the A and B sheets. This renewal involves, outside the zone occupied by the insurance insurance device, a board (not represented) housed in a groove R of the cover strip (as visible in figure 2).

As it looks great in this figure 1, axis I of the insurance corresponding to the hardware control mechanism of lock E is substantially displaced, horizontally, with respect to to the median plane J of the frame G on which it is inserted, of centered mode, the control handle K and, therefore, the square of maneuver M of the latter.

In such circumstances, a insurance return device N that is positioned between the handle K and the lock hardware box E. After all, just as you can see in these figures 1 and 2, this device of renvio de safe N, box-shaped, is positioned in a notch OR provided from the renvalso in the coating band C. Therefore, such notch O defines, at the level of this covering band C, a interruption of the tightness, when breaking the groove R of the band of coating C, which ensures in cooperation with the flange of support D of the other sheet B.

After the implantation of the sheet A, the locking hardware E and the insurance return device N, is inserted at the level of this groove O, a finishing plate P, to re-create this continuity at the level of said cover strip C. Such a finishing plate P is nonetheless incapable of alleviating the problem of the sealing that we have just finished
to evoke

Obviously, such a finishing plate P must necessarily be adapted to the distance Q that separates the inner side of the covering band C from the lock fitting box E. That is essentially due to the fact that the safety and safety device N comes , here, apply against this box of the locking hardware E. It will be noted, for this purpose, that its connection is secured by means of a fixing screw, taking into account that the locking hardware assembly E and insurance return device N it must necessarily be embedded, in one piece, in the renewal of the frame corresponding to the cover sheet
I lie A.

As for the insurance return device N whose details do not appear in figures 1 and 2 corresponding to state of the art, this is presented in the form of a box in the which are mounted in rotation, around parallel axes, by a side, a primary pinion-insurance crossed, in its center, through an opening to receive a maneuver box that cooperates, on the other hand, with the insurance of the control mechanism of the locking hardware E. On the other hand, in this box a secondary pinion-insurance crossed, in turn, by an opening to receive a maneuver box from the handle of control K. These primary pinions-insurance and secondary gear with each other through inverter sprockets, in particular two in total, which allow, during the rotation under the pinion of the pinion-safe control handle K secondary in a certain sense, which results there rotation in the same direction of the pinion-safe primary.

According to the drawings and the description of this document DE-U-91 03 676, these primary and secondary pinions-safe are arranged in the same plane in said box.

Now because of the section often standardized maneuvering squares, in the case of that of the handle or the locking hardware mechanism, the distance between axles between these pinions is very important, and therefore the displacement imparted is too large and / or the size of the box of this insurance return device turns out to be -excessive- in width, which prevents its accommodation in the notch in the renewal of the front leaf stile.

The solution is to arrange these Sprockets on different planes poses other problems. In particular, that results in a relatively important thickness of this box that can only be seen in figure 1, this notch or extends necessarily in the covering band C and in the thickness of the amount of cover sheet A.

The present invention aims to be able to propose a solution for this general problem of the size of a insurance return device, that with a view to:

- facilitate the accommodation of this device in the thickness of the carpentry;

- make it easier to make the appropriate notch provide in this carpentry to allow this accommodation;

- avoid using a plate F as it was useful in the past;

- make fixing said easier device in the lock hardware box;

- allow the placement, individually, of the hardware with respect to this device of renvio of. Insurance;

- authorize a wall mount of the latter through a notch provided from the inner side to the band of covering.

In general, the present invention aims to be able to propose a solution for such a device to insurance return is easily adaptable to each type of profile that constitutes the frame of a door, window or similar, in particular regardless of the thickness of the profile, therefore of the distance that separates the inner side of the latter from the inner side of the lock mechanism control mechanism box.

To this end, the invention relates to a insurance return device, as defined in the claim 1.

The advantages that result from this invention consists, first, in that the arrangement of Sprockets in the same plane allow to confer to the box of this return surely a smaller thickness, compatible with the thickness of a frame covering band. Therefore, to the extent that these pinions no longer necessarily carry a section opening adjusted directly to the square section of maneuver, that is that of the control mechanism or that of the handle, these pinions can be of much more section reduced without causing a problem of material thickness regarding its peripheral denture and, therefore, of the mechanical resistance of these pinions. Therefore, this box it can also have a smaller width, so that this can be mounted on wall in a notch that extends exclusively in this coating band.

According to an advantageous embodiment of the invention, the secondary pinion-insurance and / or the Primary pinion-insurance are subdivided, in their axial direction, in two cylindrical parts of which a first It has a denture capable of engaging with the inverter pinion, with the second part, in its center, a primary opening and / or secondary to receive the primary maneuver box and / or secondary of the handle and / or of the control mechanism and that substantially constitutes said primary coupling means and / or secondary.

According to a peculiarity of this invention, the part of the secondary pinion-insurance and / or the primary pinion-safe, provided with the opening for receive the maneuver box from the handle and / or said mechanism control, emerges at least partially out of the box, on the side in front of the handle and / or said control mechanism.

In fact, since on the inner side of the band a frame is inserted, with the reference G in Figure 2, has been imagined, within the framework of an inventive process, take advantage of the excess thickness conferred by this frame to accommodate there said secondary coupling means corresponding to This pinion-safe secondary. In fact, in this frame is anyway provided with a passage hole of the square of handle maneuver. To the extent that it is usually conferred on this hole a section far superior to that of such square of maneuver, these coupling means, which extend at least partially out of the box, can be positioned there without it It is necessary to provide any additional machining operation.

According to another feature of the invention, the primary pinion-insurance and / or Secondary pinion-insurance is extended, axially, for a small square of primary and / or secondary maneuver made of material with this pinion and that is protruding from the side of the box in front of the lock and / or handle hardware box.

In addition, according to an additional feature of the invention, on the primary maneuver square made of material with the primary pinion-safety is inserted a liner that forms a spacer, interchangeable type, for be adjusted to the distance that separates the case of said device of the lock hardware box.

According to another embodiment of the invention still, said primary and / or secondary coupling means are defined by an intermediate piece that involves, on the one hand, a end, male or female lace means intended to cooperate with female or male conjugate lace means It involves the primary pinion-insurance and / or secondary pinion-insurance and, on the other hand, a prolongation, or in the form of a primary maneuvering square and / or secondary that appears protruding from the side of the front box to the locking hardware and / or the handle, or that it behaves in its center an opening to receive the primary maneuver box and / or secondary of this handle and / or of this control mechanism.

According to another feature, the box of the insurance return device is provided capable of receiving means for fixing by clipping to ensure the connection with the box of the blocking hardware, being such means of fixing by clipping, here too, interchangeable type, to be adjusted to the distance between these boxes.

The present invention will be better understood by reading the description that follows and which refers to ways of embodiment depicted in the accompanying drawings.

Figure 12 is a view of the detail R of the figure 10.

As can be seen from the different figures 3 to 12 of the attached drawings, the present invention relates to a insurance forwarding device 1 which will find a very useful particular within the framework of a situation such as visible in the Figures 1 and 2 corresponding to the state of the art.

Thus, in the case of a door or window with two sheets, one, called service sheet, comes in coating the another, called semi-fixed blade. In particular, it has been represented in Figure 3, which applies to the present invention, the amount front 2, seen in partial section, of a frame 3 corresponding to the service sheet identified by the reference A in figures 1 and 2. Thus, this framework 3 involves a covering band 4 intended to come in apply against a support flange 5 of the front post 6 corresponding to the sheet 7, represented here schematically, partially and with strokes discontinuous

Very often, the front upright 6 corresponding to the other sheet 7 receives an outer frame (not represented) that closes, from the outside, the game of renvalso between the front uprights 2 and 6. On the other hand, on the side internal 9 to the covering band 4 is also applied a inner frame 10. The latter is presented in the form of a profile to often centered with respect to the median plane 11 of this door or double leaf window.

Not only close such inner frame 10 so the game of renewal 12 between the covering band 4 corresponding to the frame 3 and the front upright 6 of the other frame 7, but also allows to obtain, from the internal side to the house, a certain symmetry from a visual point of view of the carpentry.

To preserve this symmetry, but also by size motifs of the control handle 13 provided capable of acting on a locking hardware 14, said control handle 12 it is positioned at the center of this internal framework 10. Therefore, the axis of maneuvering square 15 of this control handle 13 is not it places to the right of axis 16 of the insurance corresponding to control mechanism 17 of said locking hardware 14. To this purpose, the latter, therefore the box 18 that closes this control mechanism 17, is positioned in a groove of embedment 19 provided in the front 20 of the front upright 2 corresponding to frame 3.

As it appears from the different figures 3 to 12, the insurance return device 1, according to the invention, It includes a box 22 in which they are mounted rotating around of parallel axes 23, 24, on the one hand, a primary 25 pinion-insurance intended to cooperate, to through a small block of primary maneuver 26, with the insurance of the control mechanism 17 of locking hardware 14, shown here in the form of a falba, and on the other hand, a Secondary pinion-insurance 27 planned capable of receiving the secondary control gearbox 15 of the control handle 13. This primary 25 pinion-safe and the Secondary pinion-safe 27 meshes with each other to through at least one inverter pinion 28, 29, also mounted rotating in box 22. The latter is planned capable of position in the thickness of the frame 3, between the box 18 corresponding to locking hardware 14 and said control handle 13.

As you can see in particular in the Figures 4 and 5, the primary pinion-insurance 25 and the Secondary pinion-insurance 27 are arranged in a same gear plane PL in the box 22. Such an arrangement allows confer on the latter a smaller thickness 34 which is compatible with the thickness 39 of the covering strip 4.

According to the invention, it is also provided, in combination, that the primary 25-pinion and / or the Secondary pinion-insurance 27 involve means of primary and / or secondary coupling planned to cooperate with the primary and / or secondary maneuver block 26, 15, according to the case, of the control mechanism 17 of the locking hardware 14 or of the handle 13, which are located outside said gear plane PL.

Thus, as visible in figures 4, 5, 8, 10, 11, the secondary pinion-insurance 27 is subdivided, in its axial sense, into two cylindrical parts 30, 31 of which a first part 30 wears a denture capable of engage with the inverter pinion (s) 28, 29. The second part 31, which substantially defines the coupling means secondary, it involves, in its center, the opening 32 to receive the Secondary maneuver box 15 of the control handle 13.

Thus, by avoiding prolonging the opening 32, to receive this secondary maneuvering square 15, at the level of the cylindrical part 30 provided with the denture, it can be defined of smaller diameter 33, thus facilitating its juxtaposition in the same plane, at primary pinion-insurance 25, taking into account the separation to be respected between the axis 23 of the latter and the axis 24 of the secondary pinion-insurance 27. This separation corresponds very precisely to the offset between the secondary control square 15 of the control handle 13 and axis 16 of the safety corresponding to the control mechanism 17 of the hardware
lock 14.

In such circumstances, it is not only reduced the thickness 34 of the box 22, but also its width 35.

According to another feature of the invention, visible in particular in figure 5, part 31 of secondary pinion-safe 27 provided with the opening 32 to receive the secondary maneuver box 15 of the handle of control 13 can emerge at least partially from this box 22, on the side 36 facing said control handle 13. At the end and at out, as you can see in this figure 5, that allows to reduce even more this thickness 34 of the box 22.

In addition, such cylindrical part 31 that emerges from the box 22 can be widely positioned in the thickness of the frame internal 10, as shown in figure 3. It You will notice, for this purpose, that in this framework a hole for the maneuvering square corresponding to the handle, hole that is precisely enough to accommodate this part projection 31 of said secondary pinion-insurance 27.

Obviously, the pinion-safe primary 25 could be subdivided, likewise, into two parts and adopt a configuration similar to secondary pinion-insurance 27. On the other hand, here also, the part provided with an opening to receive the square of primary maneuver corresponding to the control mechanism 17 is liable to emerge from box 22, on the side of the latter.

According to another embodiment of the present invention that can be contemplated in combination with what was already evoked, as can be seen in addition to the attached drawings, in particular of figures 4, 5, 8, 10 and 12, the primary pinion-safe 25 is extended, axially, by a primary maneuvering block 26 defining said means of primary coupling. Thus, this square of primary maneuver 26, made of material with this pinion 25, protrusion of the side 37 of box 22 opposite box 18 of locking hardware 14, with a view to cooperating with the control mechanism 17 of this latest.

By avoiding, as for the Secondary pinion-insurance 27, perform in the primary pinion-safe 25 an opening to receive the primary maneuver box 26, section 38 of this primary pinion-safe 25 can also be reduced

Here too, similar coupling means, in the form of a small maneuvering square, they could equip the secondary pinion-insurance 27. In such circumstances, this little maneuvering square would emerge from the side 36 of box 22, to present outgoing in relation to the frame 10 and allow the insertion of the handle 13.

According to another embodiment of the invention, schematically illustrated in figure 7, said means of primary and / or secondary coupling can be defined by a intermediate piece 50 which comprises, on the one hand, at one end 51, male or female embedding means 52 intended to cooperate with lace means conjugated female or male 53 that it involves the primary pinion-insurance 25 and / or the secondary pinion-insurance 27 and, on the other hand, a extension 54; 54A, or in the form of a maneuvering square that is protruding from side 37, 36 of box 22 in front of the control mechanism 17 of locking hardware 14 or handle 13, or it has an opening in its center to receive the operating block 15, 26 of this handle 13 or of this mechanism of control 17.

Although, in this figure 7, you can see a secondary pinion-insurance 27 and a primary 25 pinion-insurance that receive each of the coupling means in the form of such intermediate piece, only one of them can be provided with such means, the other being liable to receive coupling means corresponding to a of the embodiments described above.

To the extent that primary and secondary cogwheels 25 and 27 they have a section, respectively 38 and 33, independent of the of the primary maneuver block 26, respectively secondary 15, this section 38, 33 can be adapted to practically any type of separation that is currently between the shaft 16 of a lock of a locking hardware 17 and the plane 11 in the which is the control handle 13.

Finally, as you can see in the figure 3, through the preceding characteristics, box 22, of reduced width 35 and thickness 34, is capable, under such conditions, of positioning in the same thickness 39 of the covering band 4 which, in addition, can be fitted, not from the front edge 21 of the post 2 of the frame 3, but from its inner side 9.

Such a notch 40 of this inner side 9 of the band of coating 4 is made invisible by the internal frame 10. In addition, such implantation allows mounting the locking hardware 14 independently in the recess slot 9. The device of insurance return 1 is likely to be carried in cooperation, through the secondary maneuver block 26 associated with the secondary pinion-safe 25, then with the mechanism of control 17 of said locking hardware 14.

It will be noted that, compared to the state of the prior art, the solution according to the invention avoids notching the front edge of the covering band 4, design that I needed the use of a P plate, visible in Figure 2, to close this notch after assembly, which was done simultaneously, of locking hardware and insurance return device.

It should also be noted that the distance 41 that separates the inner side of the cover strip 4 and the side inside the box 18 of the locking hardware 14 is susceptible to vary depending on the type of profile used for the realization of a frame 3.

Therefore, according to the invention, on the pinion-safe primary maneuver block 26 primary 25 a liner forming a spacer can be inserted between the box 22 of this device and the box 18 that closes the control mechanism 17 of locking hardware 14. Such a liner 42 that it has an opening 43 for the passage of said maneuvering square 26, can be designing in the form of a piece of material synthetic, thickness 44 adjusted to this distance between the boxes 18 and 22.

After all, and as you can see in Figures 7 and 8, this liner 42 can receive, at the level of this opening 43, indexable drying means 45 for temporary rotation immobilization of the maneuvering square primary 26, before mounting the insurance return device 1 on frame 3, therefore before the insertion of said primary maneuver block 26 in the safety mechanism control 17 of locking hardware 14.

Obviously, such indexing means Dryers 45 can adopt different embodiments. In in particular, they can be in the form of a tongue 46 which is inserted in a notch 47 provided on the periphery of the square of primary maneuver 26, even at the level of primary pinion-insurance 27.

Obviously, such a liner 42 could also be inserted on the extension 54 of an intermediate piece 50 associated with the primary 25 pinion-insurance, even also on an eventual emerging part of box 22, on the side 37 of hardware 14, and which involves an opening to receive a maneuver box, as it is exposed above to Purpose of an embodiment of the invention.

To the extent that locking hardware 14 is inserted individually against carpentry, just like the insurance return device 1, on the other hand perfectly held through the notch 40 of the inner side 9 to the band of coating 4, the box 22 of this device 1 can, simply be clipped and no longer screwed to box 18 of the locking hardware 14.

Therefore, with reference to figures 10 to 12, clamping means 48 can be seen defined by two beams 49, 50, provided with retention means 51 in the form of nails or the like that form a recess, which extend to both sides of an element that forms a spacer 52 of thickness 55 adjusted to the separation between the device box 22 of insurance return 1 and box 18 of locking hardware 14.

Thus and at the time of assembly, box 22 of the insurance forwarding device 1 is provided with these means of clamping 48, when inserted, in openings 53 provided for To this end, his 49, knowing that the set is then clipated on box 18 as long as the count 50 of these clamping means 48 with an opening 54 in said box 18.

From the preceding explanations, it is understood, obviously, to the extent that the element that forms a spacer 52 of these clamping means 48 depends of a variable distance, the model will be proposed to the carpenter whose thickness 55 of this element forming a spacer 52 is adaptable to the profile of your carpentry.

Thus, the invention advantageously resolves the problem posed and therefore represents clear progress in This field of insurance forwarding devices.
