Description

The invention relates to a cremone bolt or locking bolt, in particular of the multipoint type, comprising a control mechanism housed in a main unit and capable of operating one or more rods of maneuver to ensure their displacement between a position of lock and an unlock position, this or one at less of these operating rods acting, moreover, on at least one locking member in the form of a deadbolt or tilting, mounted, as appropriate, free in translation or rotation, in a secondary unit of the monobloc type attached to the rear of a headrest and having in its front part an opening to the through which said deadbolt or tilting bolt, as well as its or its transmission components intended to ensure its connection to the operating rod, are engaged in said housing.

The present invention will find its application in the field of building hardware.

We already know a number of bolts or bolts corresponding to the above description and which therefore have a control mechanism housed in a main unit and in which the user intervenes, for example by means of an element with key or handle, to control one or more on the move several operating rods extending, often, from side and other of this control mechanism.

Note, in this regard, that it is common to implement this type of cremone bolt or bolt lock in a notch extending into the edge of a door, window or the like. In these conditions, the operating rod (s), arranged in this notching, are often located behind a headrest contributing to their maintenance and guidance.

In the end, this or these operating rods have for function of acting on one or more locking members which, in the very particular context targeted by the present invention, in the form of deadbolts and / or tilting bolts which, in the locked position, are able to emerge through an opening in the headrest to come and stay in a keeper arranged, in concordance, on the frame of said door, window or the like.

In fact, such a deadbolt or tilting bolt is arranged in a housing mounted at the rear of said headrest, which housing, containing, in addition, the transmission member (s) capable of connect an operating rod to the bolt and, in addition, transform a translational movement of this operating rod in one perpendicular movement of said deadbolt or in a rotation of a tilting bolt.

So far, such a secondary box able to accommodate the locking member in the form of a deadbolt or a bolt tilting is defined by a chest comprising a bottom and a wall device preserving an opening on the side of the case intended for apply on the rear face of the headrest. Said case being completed by a cover which is not secured, safe, that once the deadbolt or tilting as well as the transmission components mounted inside this trunk.

Ultimately, we realize that this very concept of housing makes it somewhat restrictive, not only its own mounting, but also the assembly of the various parts that it is intended to contain.

Thus, during this assembly it is essential to ensure a perfect positioning in the trunk, not only of the deadbolt or tilting, but also transmission members. Moreover, he must maintain these parts in relation to other. After that and at the same time of positioning the cover, it here again, take a number of precautions to ensure that the different organs are also well arranged with respect to this cover, particularly with respect to the guiding means in translation and / or rotation which may be provided this last.

We understand that, under these conditions, this assembly of the housings secondary requires on the production and assembly line a complex and careful work. In addition, if this assembly is not performed by automated means, it is necessary to assign a qualified person at the workstation concerned, besides that, at the end of assembly, a functional check is essential.

In addition, this type of case, for security reasons, requires the use of reinforcing devices which, the most of the time, increase the dimensions of this case, even even, oblige, in certain cases, to design locking bolts on the wall.

Finally, we have seen that, in the past, the different parts forming said housings tended, in some configurations, to take play from each other to so much so that the moving parts they contained were not more properly maintained or guided and resulted in disturbances or the blocking of the lever or lever-bolt.

In this regard, it is also known from document US-A-5,373,716 a cremone bolt which more particularly responds to the preamble of claim 1. Thus, there is a control mechanism housed in a main unit able to intervene, through operating rods on locking members mounted in monobloc type secondary boxes attached to the rear of a headrest. Note, here, that the locking member, under shape of a cylindrical bolt, moves inside an orifice formed in a support mounted movable in vertical translation in the housing and secured to the operating rod. The box presents, on its lateral faces, lights adopting a shape comma allowing the passage and guidance of a through rod the body of the locking bolt.

Thus, during the setting in motion of the operating rod, the latter communicates a vertical movement to said support moving inside the case and driving, in its movement, said locking bolt. This one due to the displacement of said rod relative to the housing inside the comma-shaped lights, will be able to move back or forward in strike direction and crossing an opening in the rod maneuver.

It will be observed that the operating rod is made integral with the support which, when driven in a translational movement vertical, drives with it and vertically said bolt of locking. By the arrangement and the displacement of said rod relative to the support and the housing, the movement control of this support by said rod causes, simultaneously, the advance and the removal of said locking bolt. The movement of the latter is, therefore, therefore, complex and not limited to displacement unidirectional with respect to the housing and perpendicular to the headrest or even a simple tilt.

The invention therefore proposes to define housings secondary not only of the monobloc type, but comprising, in In addition, all the features to directly ensure the holding and guiding a deadbolt and / or tilting. The invention also aims to facilitate the mounting of parts in such a case, so that this operation can be carried out automatically on a cremone line or lock-bolt.

Finally, the invention aims to design a set of reliable operation. On this occasion she also sought to solve the problem of the transmission of the movement of a rod operating on a locking member, this ensuring a good distribution of forces on the different parts.

The invention is defined by the features of claim 1.

The invention relates, more particularly, to lock bolts 1 in particular of the multipoint type as shown in the figure 1 of the attached drawings.

Such a cremone bolt or locking bolt comprises a main case 2 containing a control mechanism (not visible), by through which the user is able to act, for example at by means of a key element or a handle, on one or more rods operating 3 in order to ensure their movement between a position and an unlocked position. In fact, such as visible in Figure 1, this or these operating rods 3 can extend on one side or on either side of the housing main 2.

This or these operating rods 3 act, moreover, on the minus a locking member 4 which, in the particular case of the present invention is in the form of either a deadbolt 5 corresponding to the embodiment illustrated in FIGS. 2 to 4, or of a tilting bolt 5A as visible in FIGS. 5 to 7. It will be remembered, in this regard, that one can perfectly imagine a locking member taking up, simultaneously, the characteristics of a deadbolt and a tilting bolt. If one such a solution is not very common, it should be considered, however, that it also fits into the application song of the present invention.

This deadbolt 5 or tilting 5A is in fact mounted, as the case may be, free in translation and / or rotation in a secondary housing 6 disposed at the rear of a headrest 7. More particularly this headrest 7 has dimensions adjusted to those of the housing secondary 6 or even extends, as shown in the Figure 1, substantially over the entire length of the lock 1. At this headrest 7 are then, also made integral all the other secondary boxes 6 just like the main box 2.

Going back to secondary box 6, hosting a deadbolt 5 or a tilting bolt 5A, it is of the one-piece type. So, he has two side walls 8, 9 integral with each other at across a peripheral wall 10 preserving, in the front part 11 of this housing 6, an opening 12 through which one can come to engage said deadbolt 5 or tilting 5A, as well as its transmission member (s) 13, 13A, intended to ensure the connection with the operating rod 3. In fact, we observe that the front part 11, comprising the opening 12, is that which is intended to be mounted, by riveting, screwing or the like, on the headrest 7. Consequently, once fixed on the latter, said box 6 can not, in any case, deform or disassemble or still present any game which would result in a bad maintaining the guidance of the elements it contains.

In addition, such a one-piece housing 6 can be produced by molding by injection, or even by machining, ultimately authorizing the use of resistant materials and / or capable of undergoing thermal or surface treatments avoiding the use of devices reinforcement often essential in the case of non- monoblocs and composed of several parts that it is suitable to assemble.

Thus, the secondary housing 6, according to the invention, defines a housing 14 intended to accommodate the deadbolt 5 or the bolt tilting 5A, as well as its transmission member (s) 13, 13A. It further comprises holding and guiding means 16, 16A, respectively, of such a deadbolt 5 or of a tilting bolt 5A.

As shown in Figures 2 to 4, these means of holding and guide 16 are in the form of guide flanges 17 arranged in the housing 14 extending parallel to the axis of displacement 20 of said deadbolt 5, the latter taking position between these guide flanges 17, 18.

These holding and guiding means 16 may also arise. in the form of a groove and / or groove on the internal side 19 of one or more side walls 8, 9 and intended to cooperate, respectively, with a groove and / or a groove on the deadbolt 5, this or these grooves and / or grooves extending in a direction parallel to the axis of displacement of said deadbolt 5.

The transmission member 13 is designed in the form of an easel 21 housed in this secondary housing 6 and cooperating, through at least one latching finger 22, with the operating rod 3. This easel 21 therefore moves in a direction parallel to that of this operating rod 3 and, therefore, perpendicular to the movement of the deadbolt 5. More precisely, this comprises on at least one of its lateral faces 23, 24 a drive finger 25 which is housed in a light in "Z" shape 26 (visible in Figures 2 and 4), machined in the bridge 21 and ensuring this transformation of the movement of this last in a perpendicular movement of the deadbolt 5. A About the training finger 25, it corresponds to an axis crossing the deadbolt 5 and presenting itself projecting on one or the lateral faces 23, 24 of the latter.

Preferably, the bridge 21 is split in its part 27 comprising the light in the shape of a "Z" 26, this so as to act on both sides on the deadbolt 5 which comprises, in these conditions, on each of its lateral faces 23, 24 such a finger 25 corresponding in fact to the projecting ends of an axis crossing this deadbolt 5. We will observe, in this regard, that the application of a lateral force on only one of the sides of the bolt 5, tends to cause, due to the slight operating clearance too much friction. The preferred embodiment using a split bridge 21 therefore allows to avoid this phenomenon.

Note, moreover, according to a feature of the present invention, that the free end 28, 29A of the axis defining this or these fingers 25, moves in a transverse groove 29 (parallel to the axis of movement 20 of the deadbolt 5) formed on the internal side 19, as the case may be, of the side wall 8 and / or 9 of the secondary housing 6. It is understood, under these conditions, that becomes completely impossible even after multiple stresses, that the easel 21 is released from the deadbolt 5.

Figure 4 illustrates, schematically, the different stages mounting 1, 2, 3 of such a deadbolt 5 and its housing secondary 6 on the headrest 7 of a lever or lever-bolt 1. More precisely once the easel 21 hung on the bolt dormant 5, the assembly is simply slid inside the secondary box 6 through the opening 12 which it comprises in its front part 11. We then come to ensure cooperation between the hanging finger 22 of the bridge 21 with the rod maneuver 3 before fixing said secondary housing 6 on the headrest 7 preferably by riveting.

As for the means for holding and guiding 16A of a tilting bolt 5A in such a secondary housing 6 monobloc, they consist of a single axis 30 extending, perpendicularly, inside the secondary housing 6 and on which is mounted, in rotation, said tilting bolt 5A. More specifically, at least one of the walls side 8, 9 of said secondary housing 6 has an orifice 31 adjusted to the passage of this axis 30, this orifice 31 coming to be located right of a bore 32 formed in the tilting bolt 5A when it is arranged inside said secondary box 6. Thus, during assembly, this axis 30 is engaged, successively in this orifice 31, then in the bore 32. This movement is continued until its end 33 comes to be housed in another orifice arranged in the opposite wall of said secondary housing 6 or still in a simple cavity present on the internal side 19 of this opposite wall. Ultimately, a crimping or riveting performed at the orifice (s) 31, present in the wall (s) side 8, 9 of the housing 6 prevents any risk of unexpected dismantling of axis 30.

It will be observed that as regards the transmission member 13A there borrows a configuration similar to that of the organ of transmission 13 intended to act on a deadbolt 5. However, in this case, the easel 21 has in its part 27 split, a drive axis 25A while said tilting bolt 5A has a comma-shaped light 26A through, specifically, by this drive axis 25A. The interaction between this drive axis 25A and this light 26A, when moving the easel 21 under the impulse of an operating rod 3, conduit, specifically, the tilting of the bolt 5A in a position of locking or unlocking.

The assembly and mounting operations are also little different from those to which reference has been made about a locking member in the form of a deadbolt 5.

So, as visible in figure 7, we come, first of all, hang the easel on the 5A tilting bolt, this set is, then inserted into the secondary box 6 through its opening 12 present in its front part 11. At this stage, it should, however, carry out the mounting of the axis 30 constituting, substantially, the holding and guiding means 16A of this tilting bolt 5A. In the end, we come to ensure cooperation between the operating rod 3 and the easel 21 before fixing, in particular by riveting, said secondary housing 6 on the headrest 7.
