Description

The invention relates to a cremone bolt or locking bolt comprising at least one case attached to the back of a headrest and housing a mechanism for the movement control from to minus an operating rod extending above and / or below said housing, at the rear of the headrest, this or these operating rods entering said housing through openings provided for this purpose in order to cooperate, using appropriate connecting means, with an interacting easel with said control mechanism.

The present invention will find its application in the field of the building hardware and concerns everything in particular, bolt-type locking fittings or lock-bolt.

Most of these cremone bolts or lock bolts meet the above description and therefore include at least a case attached to the back of a headrest and containing a control mechanism allowing to act on one or more operating rods extending above and / or below of this housing, at the rear of said headrest.

Generally, said control mechanism allows a user to act, for example by means of a handle or a button control or using a key element on an organ of transmission called, usually, easel which comes to be connected, using appropriate connecting means, the end of an operating rod engaged in this housing. Note that this includes, for this purpose and in terms of its upper and / or lower edge, an opening adjusted to the section of said rod. So the bond between this last and the easel is carried out, often, by means of hanging under a ton of a rectangular light in the end of this rod and in which is able to penetrate a gripping finger of parallelepiped shape complementary to the easel.

Such a cremone bolt or locking bolt is, very frequently embedded in a rebate groove of the upright and / or a cross member of a door, window or the like, the headrest coming to house all the organs to which it was made reference above.

In this regard, it should be observed that if these cremones or locks and bolts are manufactured to standard dimensions, especially with regard to the length of their headrest and their operating rod, it is necessary, for a manufacturer, to be able to also satisfy requests specific. If it is of course possible, under these conditions, to adjust this length of the headrests and rods of factory operation, before assembly of the lever or lever-bolt, this complicates, significantly, the management of manufacture of these bolts or bolts, all especially when these specific requests match to very small series.

In particular, the bolts or bolts-locks coming from equip renovation joinery or intended to meet specific requests must be made, almost systematic, of a recovery with regard to the length of their headrest and their operating rods.

Such a difficulty is encountered, in particular, in the frame of the bolts or bolts-locks caused to extend over the entire length of an upright or a cross opening. Even more so when the free end of a rod maneuver is capable of constituting, in itself, an organ of locking insofar as this free end is provided able to appear protruding at one end of this amount or this cross so as to fit into a keeper arranged in correspondence on the sleeping frame of the door, window or the like.

In fact, apart from these specific cases corresponding to the renovation or special requests, the problem has become even more complex, insofar as the rebate play has tends to be reduced to the bare minimum so that one does can no longer afford a rough adjustment between the length of a cremone bolt or bolt lock and, for example, the height of the amount of a door or window opening on which this cremone bolt or bolt lock must be reported. Indeed, if the rod, the headrest or the exit guide rod were to create space, under these conditions, at level of this rebate, this could cause difficulty operating this door or window. AT conversely, a too short rod does not allow to obtain a proper engagement of its end in the keeper corresponding on the sleeping frame.

If, to date, the carpenters have already equipped themselves for some, of a small press which allows them, by therefore, to cut to the desired length a rod maneuver and, simultaneously, the headrest that houses it individual cross-checking of one or the other is not possible through this tool. Also, it is not theirs possible to precisely adjust these elements to each case specific they encounter. Note that to allow them such an operation these bolts or bolts-locks when delivered to these carpenters are devoid of the rod exit guide which is usually fixed on the end of the headrest for precise guidance from the end of the rod. This rod exit guide is present, then, in the form of an accessory which is no longer fixed on the headrest, but which is intended to cover the end of the latter at the time of the installation of the lever or lever-bolt, while suitable fixing means allow to make it directly united, carpentry.

To this it should be specified that a rod exit guide coming to cap the end of the headrest and fixed individually on the joinery increases the fitting operations of such a lever or lever-bolt.

Ultimately, the present invention proposes to remedy to the aforementioned problems through a lever or lever-bolt whose free end of an operating rod can be moved away from that of the headrest by pivoting in a plane parallel to the latter, this pivoting being precisely authorized through the connecting means of this rod with the elements of the control mechanism located, therefore, internally to the housing.

To this end, the invention relates to a cremone bolt or bolt lock comprising at least one housing attached to the rear of a headrest and sheltering a mechanism for the control in displacement of at least one operating rod extending above at and / or below said housing at the rear of the headrest, this or these operating rods penetrating into said housing through openings provided for this purpose in with a view to cooperating, using appropriate means of connection, with an easel interacting with said control mechanism, characterized by the fact that said means for connecting a operating rod with an easel are of the articulated type, while said rod is further defined at least at height of the opening in the case of width less than this opening, in order to authorize the pivoting, according to a determined amplitude of said operating rod in a plane parallel to said headrest.

The advantages of the present invention consist of what rod and headrest of a lever or lever-bolt, pre-assembled in the factory, can be cut, individually, lengthwise, without the need to disassemble one of them.

In addition, this avoids multiplying stocks and allows with cremone bolts or cremone bolts to cover all needs. Of more, through the present invention, the carpenters can more freely define new door standards or windows with reduced section of the elements of the opening frame and the sleeping frame. Indeed, the bolts or bolts-locks, object of the invention, are able to consolidate such doors or windows by authorizing, first of all, a reduction in rebate play and ensuring better engagement of the rod exits in the strikes.

Other objects and advantages of the present invention will appear during the description which follows relating to an embodiment which is given only as indicative and non-limiting example.

As shown in the figures in the attached drawing, the present invention relates to the field of hardware building and, more particularly, that of the fittings of bolt-type lock or bolt-lock for door, window or the like.

As shown in Figure 1, such a cremone bolt or cremone bolt 1 is very often mounted on the upright 2 or on a cross member of the opening 3 of such a door or window 4. In fact, this cremone bolt or lock bolt 1 is usually embedded in a groove provided for this purpose in rebate of this amount 2 or this cross and includes at least one box 5, marked in broken lines in FIG. 1, attached, for example by riveting or otherwise, to the back of a headrest 6. This comes, in a way, to house the whole organs of this cremone bolt or cremone bolt 1 arranged in said recess groove of the upright 2 of the opening 3.

The housing 5 contains, in fact, a mechanism (not shown) for the displacement control of at least one rod maneuver 7 extending, behind the headrest 6 above and / or below this box 5.

Thus, this or these operating rods 7 penetrate into said housing 5 through openings 8 provided for this purpose at the level of the upper edge 9 and / or lower edge 10, of this last immediately behind the headrest 6. On the Figures 2, 3, 4 and 8, this opening 8 extends between the two side walls of the housing 5, materialized, here, by the two rectangular lights 11 made in the headrest 6, symmetrically with respect to its longitudinal median plane 12, and intended for the reception of riveting lugs which comprises the front edge of said side walls therefore, before and rear, corresponding to the housing 5. It should however remember that the present invention is in no way limited to such a riveting solution to guarantee the connection of this housing 5 to the headrest 6 and which is given, here, as example.

Anyway, the end 13 of an operating rod 7 introduced at this level of the housing 5 cooperates, using means appropriate link 14 with an easel 15 interacting with the control mechanism. So, this easel 15 is usually considered to be an integral part of this cremone bolt or bolt lock mechanism 1.

The different figures of the attached drawing represent, all particularly a bolt or lock bolt 1 of which the free end 16 opposite to that 13 of the rod maneuver 7 is able to define a locking member, in that sense that she is able to stand out prominently at a end 17 of the upright 2 or, as the case may be, of a cross opening it 3 so as to come to cooperate with a keeper arranged in agreement on the sleeping frame, this when this cremone bolt or locking bolt is brought into the locking position.

We understand, of course, that under such conditions but also for the reasons already mentioned above, the length of this operating rod 7 all retort that of the headrest 6 which shelters it must be strictly adjusted to the dimensions of this opening 3 so that the carpenter is brought in, very frequently, or ask the manufacturer for length updates rods and / or headrests, or proceed to their recutting using a suitable press. Other constraints may naturally require a cross-check as mentioned and without nothing to change the problem posed and its solution.

Anyway, the present invention aims to make easier this individual cross-checking of a headrest and / or a operating rod corresponding to a lever or lever-bolt pre-assembled.

In particular, according to the invention, the connecting means 14 allowing the end 13 introduced into the housing 5 an operating rod 7 to cooperate with the easel 15, are defined as an articulated type, while said rod maneuver 7 has, in addition, at least up to the opening 8 in the housing 5, a width 18 less than that of this opening 8, in order to authorize pivoting, according to a determined amplitude α, of said rod maneuver 7 in a plane parallel to the headrest 6. This allows, consequently, to move away, angularly, the free end 16 of this operating rod 7 relative to that 19 of the headrest 6 and, ultimately, to independently cross one and the other.

It will be particularly noted that to carry out this cross-checking the operator is no longer obliged, as for the past, to print, as the case may be, on the operating rod or to the headrest any bending likely to cause permanent deformation of these elements.

Substantially, the articulated type connecting means 14 are defined by an associated latching finger 20, according to the case, at the easel 15 or at the end 13 of the rod operation 7, this catching finger 20 being provided capable of coming fit into a light 21 formed at said level end 13 of the operating rod 7, respectively, in the easel 15, this latching finger 20 and this light 21 being configured so as to allow the pivoting of the operating rod 7 relative to said easel 15 at least according to an angle of rotation of amplitude α. So like shown in Figure 4, the latching finger 20 and the light 21 can be defined as circular section.

However, it will be noted that it is quite usual, in the state of technique, to spare at the level of the rod maneuver, a parallelepiped light, more particularly of rectangular shape in which comes insert a hooking finger of the bridge of conjugate shape. In such a configuration it is enough to modify and therefore to adapt the shape of the fastening finger 20 relative to the light 21 of square or rectangular shape, to lead to the goal sought. In particular, as visible in the Figures 2, 3 and 8, said attachment finger 20 can adopt a teardrop shape with the widest part 22 in width important is adjusted to the width of the light 21 of shape parallelepipedic while the tapered part 23, presenting a certain mobility in this light 21, allows the operating rod 7 to pivot relative to the headrest 6. Again, we can imagine associating the rod with the finger attachment 20, the easel receiving the light 21.

It will be observed that it suffices for the operating rod 7 of ability to rotate relative to headrest 6 in one direction 24 so that we obtain the desired result. Also, the width 18 of the operating rod 7 up to the opening 8 in the housing 5 can be adjusted, for the result to be obtained, through a simple cut 25 made in one of the side edges 26 of this operating rod 7, at this opening 8. This cutout 25 is thus defined so as to allow, when pivoting the operating rod 7, to the wall of the housing 5, located on the side corresponding to pivot direction 24 to register in this cutout 25.

In the context of a bolt or bolt lock 1 comprising a operating rod 7 whose free end 16 is likely to define a locking member, a guide rod outlet 27 is generally fitted to the end corresponding free 19 of the headrest 6, this in the manner shown in figure 5.

In fact, the invention also relates to such an exit guide. rod 27 particularly suitable for a lever bolt or lever bolt 1 with the characteristics previously described including the headrest 6 and an operating rod 7 are brought to be intersected. We understand that under such conditions, this cremone bolt or bolt lock 1 cannot be pre-equipped at the factory, of this rod exit guide 27, which cannot only be associated once the cross-checking has been carried out.

However, it is necessary to avoid, under these conditions, that the fact, for a carpenter to have to equip, himself, the cremone bolt or bolt-lock of this rod exit guide 27 does not complicates its task.

Also, according to the invention, this rod exit guide 27 is advantageously has the form of a section profile U-shaped defining a channel 28 designed to accommodate, in view to provide guidance, the end 16 of the rod operation 7. This U-shaped profile has a bottom 29 at the longitudinal edges from which extend side walls 30, 31 whose upper edge 32 is provided capable of bearing on the rear face 33 of the headrest 6.

At one end 34, this rod exit guide 27 can be provided with a hooking return 35 having a opening 36 for the passage of the operating rod 7 and coming to hang on the free end 19 of the headrest 6. However, it is understood that such a catch return 35 can generate a protrusion at the rebate of a door or window insofar as it is superimposed on the headrest 6 at the front thereof. Also and to avoid this, at height of its end 34, the side walls 30, 31 of this rod exit guide 27 can be provided on their upper edge 32 of a fixing lug in particular by crimping, marked 50 in Figure 6, which is provided capable of cooperate with the end 19 of the headrest 6 shaped as result.

Furthermore, from the bottom 29 and internally to channel 28 extends a longitudinal boss 37 on which is able to come and fit the operating rod 7 through a oblong light 38 formed in the latter for this purpose. In done, this boss 37 receives, on the one hand, means of positioning 39 of the rod exit guide 27 relative to to the headrest 6 and, on the other hand, means 40 for its fixing on a joinery or the like.

Substantially, the positioning means 39 consist in a positioning pad 41 adjusted to an opening 2 in the headrest 6, taking into account, in this regard, that this stud of positioning 41 can still define a riveting stud allowing to bring together, in a first step, said rod exit guide 27 of this headrest 6, before installation of the cremone bolt or lock-bolt 1 on the joinery.

As for the fixing means 40, they consist of a perforation 43 for the passage of a fixing screw or similar, the latter also passing through a hole 44 made, in correspondence, in the headrest 6.

It will be noted, in this regard, that prior riveting of the guide rod outlet 27 on the headrest 6 by means of the stud positioning 41 allows the headrest 6 and the rod exit guide 27 from the joinery by means of a one and the same fixing screw.

The ribs for positioning the opening 42 and the hole 44 for receiving the positioning pad 41, on the one hand, and for the passage of a fixing screw, on the other hand, being determined from the free end 19, which can be cut, of the headrest 6, this opening 42 and this hole 44 are necessarily made after the cutting of this headrest 6, preferably by means of the same tool, therefore the press to perform this operation.

Furthermore, the light 38 in the operating rod 7 is, it, defined, of sufficient length and, therefore, able to match the boss 37 of the rod exit guide 27, regardless of the length at which the rod 7 is likely to be cut in relation to a length standard.

It is understood, in view of the above description, that the present invention makes it possible to respond, advantageously, to the problem encountered in the context of the state of the art, so it’s a big step forward, especially for carpenters who see in this type of cremone bolt or cremone bolt the possibility of adapting them, in length, with great ease.
