Description

The invention relates to a rod exit guide for a lever. or locking bolt according to the preamble of claim 1.

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

In this regard, most of these bolts or bolts have at least one housing attached to the rear of a headrest and containing a control mechanism allowing act on one or more operating rods coming from extend above and / or below this box at the rear of said headrest.

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

If these cremone bolts or locks are manufactured, usually to standard dimensions, especially with regard to concerns the length of the headrest and rod maneuver, it is necessary, for a manufacturer, to be able also meet specific requests. It is well safe, possible, under these conditions to adjust this length of factory headrests and rods, front assembly of the cremone bolt or cremone bolt, this comes significantly complicate the manufacturing management of these cremone bolts or bolts, especially when these specific requests correspond to very small series.

In fact, we encounter such difficulties, everything particularly, in the context of a lever bolt or lever bolt caused to extend over the entire height of an amount or the length of a cross member of an opening and that the end free of an operating rod is able to constitute, in itself, a locking member, insofar as this free end is provided capable of being projecting at one end of this upright or cross, way to fit into a keeper made in correspondence on the door, window or similar.

In addition, if it had previously been necessary to cross-check the rods and headrests for standard bolts or bolts to adapt them to specific new cases such as renovations or special requests, the problem has become more complex again insofar as the rebate play has tend to be reduced or increased so that one cannot more afford to operate an identical length rods and headrest of a lever or lever-bolt.

Consequently, if the rod, the headrest or the guide exit of a rod came to create in these conditions, a additional space at this rebate, this could cause operating difficulties for the window. At the same time, a too short rod does not allow obtain suitable engagement from its end in the corresponding strike on the sleeping frame. Conversely, a too long rod does not allow complete locking, the maneuver being blocked due to the end stop of rod in the same keeper.

In addition, if the carpenters are already equipped for some, a small press that allows them to cut the desired length of an operating rod and, simultaneously, the headrest that houses it, the individual cross-checking one or the other is not possible through this tool. Also, they don't have the opportunity to adjust precisely these elements to each of the specific cases they are brought to meet.

Note also that to allow such an operation of recutting these bolts or bolts, when they are delivered to these carpenters do not have the exit guide rod which is fixed, usually, on the end of the headrest to ensure, precisely, the guidance of the end of the rod.

In this regard, this rod exit guide is presented, usually in the form of a square piece from dress the angle of the opening frame which is able to projecting the end of the rod. Also, one of the wings of this square piece comes on the wall, externally, on the headrest. For a good hold of the assembly, each of the wings of this square piece is provided with an opening for the passage of a fixing screw coming to cooperate with the carpentry. Under these conditions, one of these fixing screws comes through, both the headrest and the operating rod, this being necessarily provided an oblong hole to the right of this screw to give it the mobility required. Now, this somewhat upsets, in these new conditions, the intersection of such a rod maneuver and the corresponding headrest.

It is also known, from document FR-A-2,747,723, a guide rod exit in the form of a fork comprising a base adapted to be housed in the bottom of the groove built-in at the joinery. This guide to rod outlet is also provided with a extending wing parallel to the base by covering, on the external side, the end part of the rod, while a strip of guide extends between the base and the wing and has a through opening adapted to the passage of the end of this rod. The base has an opening for the passage a fixing screw located beyond the wing in order to be accessible. As for the rod, it also has a hole allowing the passage of this screw and the tool fixing when installing the cremone bolt on the opening.

In fact, as is evident from the description of this document FR-A-2.747.723, this rod exit guide is all particularly suitable for a cremone bolt fitted with a rod particular configuration and devoid, moreover, of any headrest.

document FR-A-2.365.016 also discloses a process for dimensioning at least one end of a lever to headrest by simultaneous cutting of the headrest and the rod the dimension of the opening knowing that the simultaneous cutting of the headrest and rod is made at an acute angle by relative to the longitudinal axis of the headrest and this rod, this when the latter is in position unlocked. It is further described in this document a rod exit guide device coming to fix the end of a cremone bolt with a headrest on the opening, this device in the form of a square comprising a vertical wing and a horizontal wing, under the latter and at the rear of said vertical wing extending a rail of guiding in the form of a U-shaped section profile suitable to receive, for guidance, the free end of the operating rod. More specifically, the wing vertical of the square is caused to extend in front of the headrest, while the upper edge of the side walls parallel of the “U” profile defining the guide rail comes to apply on the rear side of this headrest. Note that said guide rail communicates with a opening at the horizontal wing of the bracket for the passage of the free end of the operating rod.

It is also known from document FR-2,458,655 a device for fixing and guiding the end of a cremone bolt to headrest. This device borrows the farm from a profile "U" shaped section with a bottom arranged parallel to the end of the headrest of this lever. From this bottom extend two parallel side walls between which slides the free end of the operating rod. Note that the upper song of these side walls is provided with a matching riveting tab with corresponding openings at the level of the headrest. In its lower part the bottom of this device, or rod exit guide, is extended by a blade having an opening for the passage of a fixing screw. Therefore this opening is located at the right of an orifice through at the level of the headrest and an oblong opening in the operating rod to allow the engagement of said fixing screw.

Finally we still know from document FR-A-2.334.807 a rod exit guide device incorporating a design substantially similar to that described in the document cited above FR-A-2.365.016. In this case, however, this device, in the form of a square, comprises a wing horizontal and a vertical wing coming to constitute, substantially, the extension of the headrests of a lever extending in rebate, respectively of the crosspiece and the amount of an opening receiving said lever. Note, again that the horizontal wing has a sole capable of extending in a recess groove provided at a cross of this opening, this sole having an opening for the passage of a fixing screw to make it integral said carpentry device.

• guider les vis de fixation venant traverser ladite têtière en direction de la menuiserie ;
• garantir la liaison têtière-tringle de manoeuvre ;
• assurer le guidage de cette tringle de manoeuvre par rapport à ladite têtière.

It should also be noted that these cremone bolts or locks of the state of the art are usually provided with screw guides which are fixed by riveting, at the rear of the headrest and which fulfill the following functions:

• guide the fixing screws coming through said headrest in the direction of the joinery;
• guarantee the headrest-maneuver rod linkage;
• guiding this operating rod relative to said headrest.

Note, in this regard, that a screw guide is fitted in a oblong light in the front operating rod to be riveted on the headrest which allows it, precisely, to provide the aforementioned guidance function.

Very generally, only one screw guide comes, thus, equipping a headrest near the free end of the latter, in below the intersection limit.

Finally, we see that, in this context, the screw guide and the rod exit guide are defined by parts separate which should be mounted which complicates, of course, the latter. In addition, the very presence of a such a screw guide from the factory connecting the rod and the headrest, prevents, in itself, from overlapping, individually, one either.

However, these technical solutions were and / or remained satisfactory as long as the length of the headrest and the rod remained the same.

Ultimately, the present invention is intended to respond to the above problem through an exit guide from rod which is not only able to ensure a perfect maintenance of the end of an operating rod intended for define a locking member capable of cooperating with a waste, but also to contribute to the connection and guidance an operating rod relative to the headrest which shelters it. Ultimately, this rod exit guide is must be able to perform the functions of a screw guide in the since it can also receive at least one screw fixing intended to rigidly fix the assembly in a groove provided for this purpose on the opening frame. Else apart, it should only cause minimal bulk, or even no footprint.

Thus, the invention relates to a rod exit guide for cremone bolt or cremone bolt provided capable of taking a position in rebate of a door, window or similar frame, this rod exit guide, on the one hand, coming to be the end of an upright or a cross member of said chassis opening, end with respect to which is able to projecting, in the locked position, a rod operating in order to cooperate with a keeper arranged in correspondence on the frame of this door, window or analogous, and, on the other hand, in the form of a "U" section profile designed to accommodate, in view to provide guidance, the end of the operating rod and having a bottom at the longitudinal edges of which extend from the side walls whose upper edge is even to lean on the rear face of a headrest. More particularly this rod exit guide still has positioning means relative to the headrest, as well means for its attachment to the opening frame, said positioning means consisting of a stud positioning surmounting a longitudinal boss formed in the bottom of the U-shaped profile, on this longitudinal boss being able to fit the operating rod through a oblong light provided in the latter for this purpose, said positioning pad being adjusted to an opening in the headrest, while the fixing means consist of a perforation for the passage of a fixing screw or the like crossing said longitudinal boss and communicating with a corresponding hole in the headrest.

Note that such a rod exit guide in the form of a “U” profile is suitable for being fitted with jointing and without relief in the groove of the headrest and rod,

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.

The understanding of this description will be facilitated by referring to the attached drawing in which:

• Figure 1 is a schematic representation of the opening of a window equipped with a cremone bolt or bolt lock according to the invention;
• Figure 2 is a schematic representation in elevation and in section of the free end of an operating rod and a headrest, the latter receiving a rod exit guide according to the invention and according to a first embodiment of production ;
• Figure 3 is a schematic representation in elevation and in section of the rod exit guide shown in Figure 2;
• Figure 4 is a schematic and plan view of this rod exit guide corresponding to Figures 2 and 3;
• Figures 5, 6 and 7 correspond to representations similar to Figures 2, 3 and 4 for a rod exit guide according to a second embodiment.

As shown in the figures in the attached drawing, the present invention relates to the field of hardware building, 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 bolt lock 1 is very often mounted on the upright 2 or on a cross member of the opening frame 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 Figure 1) attached, for example by riveting or otherwise, to the back of a headrest 6. This sort of shelters 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 operation 7 extending at the rear of the headrest 6 above and / or below this box 5.

The different figures of the attached drawings represent, in particular, a cremone bolt or bolt lock the free end 8 of an operating rod 7 is suitable for define a locking member in the sense that it is in able to appear protruding, at one end 9 of the upright 2 or, as the case may be, a cross member of the opening frame 3, so as to cooperate with a keeper arranged in accordance on the frame, this when this lever or lever-bolt is brought into the locked position.

We understand, of course, that under such conditions but also for the reasons already mentioned above, the length of this operating rod 7, just like that of the headrest 6 which shelters it must be strictly adjusted to the dimensions of this opening frame 3 so that the carpenter is brought in, frequently, or to ask the manufacturer to perform this cut to length, or to proceed, itself, to the cutting, by means of an adequate press, these rods and headrests of bolts or bolts.

Other constraints may, of course, require a cross-checking as mentioned and without changing the problem and his 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.

• assurer un parfait maintien et guidage de l'extrémité libre 8 de la tringle de manoeuvre 7 ;
• garantir la liaison têtière tringle de manoeuvre
• assurer le guidage de la tringle de manoeuvre par rapport à cette têtière ;
• et permettre la fixation de l'ensemble guide de sortie de tringle-têtière au châssis ouvrant.

In particular, this invention consists of a rod exit guide 10 capable of fulfilling the following functions:

• ensuring perfect support and guidance of the free end 8 of the operating rod 7;
• guarantee the linkage of the operating rod headrest
• guiding the operating rod relative to this headrest;
• and allow the fixing of the guide rod outlet guide assembly to the opening frame.

In fact, we are not simply satisfied with a function of guiding the end of the operating rod, but ensuring, in addition, a guided connection between this rod maneuver and headrest and defining ways to fixing the latter on the joinery, such a guide rod exit exempts the manufacturer of these cremones or bolts and bolts to multiply or complicate operations previously known, which ultimately allows at this cremone bolt or cremone bolt, before installing the rod exit guide relative mobility of the rod with respect to its headrest allowing them to be separated substantially, either by scissor effect or by bending for cross-check, individually, one and / or the other.

Thus, according to the invention, this rod exit guide 10 is advantageously has the form of a section profile in “U” defining a channel 12 provided capable of accommodating, in view for guiding, the end 8 of the rod operation 7. In particular, this U-shaped profile 11 has a bottom 13 at the longitudinal edges of which extend from the side walls 14, 15 whose upper edge 16 is provided capable of bearing on the rear face 17 of the headrest 6. According to a feature of the invention in terms of bottom 13 of the “U” profile 11 inside the channel 12, are provided means 18 for positioning the outlet guide rod 10 relative to the headrest 6, as well as means 19 with a view to fixing it to a carpentry more particularly on the opening frame 3 of a door or window.

Substantially, the positioning means 18 consist in a positioning pad 20 overcoming a boss longitudinal 21 formed in the bottom 13 of the U-shaped profile 11 on this longitudinal boss 21 being able to come to fit the operating rod 7 through an oblong opening 22 provided in the latter for this purpose. In fact, said pad positioning 20 is adjusted to an opening 23 in the headrest 6, taking into account, in this regard, that this positioning pad 20 can also define a riveting stud to make integral, in a first step, said outlet guide of rod 10 of this headrest 6 before fitting the lever or lock-bolt on the joinery.

As for the fixing means 19, they consist of a perforation 24 for the passage of a fixing screw or analog passing preferably through the boss longitudinal 21 and communicating with a hole 24A formed in correspondence in the headrest 6.

The connection at the level of this headrest 6 and the guidance, properly speaking, from the free end 8 of the rod operation 7, is ensured by means of link 25 connecting this rod exit guide 10 to the free end 26 of the headrest 6.

According to a first embodiment illustrated in the figures 2 to 4, one end 27 of this rod exit guide 10 is provided with a hooking return 28 having a opening 29 for the passage of the end 8 of the rod maneuver 7 and coming to hang on the free end 26 of the headrest 6 or, not shown in the figures, to butt the end of the headrest, which is rendered possible due to the proximity of the headrest attachment by the rod exit guide.

It will be observed that such a catch return 28 coming superimposing, in a way, on the headrest 6, can present a very small thickness 30 to generate a space also reduced as possible in rebate of the opening frame 3. However, in certain cases this extra thickness produced by this snap return 28 in door rebate or window can be considered undesirable due, specifically, a very small rebate play.

Also, to avoid this, the connecting means 25 can, such as shown in Figures 5 to 7, take the form of fixing lugs 31 at the level of the upper edge 16 of side walls 14, 15 at the level of the end 27 of said guide rod outlet 10, such fixing lugs 31 defining, in fact, provided crimp tabs capable of be crimped into openings 32 made in correspondence at the end 26 of the headrest 6.

It should be noted that the positioning dimensions of opening 23 and hole 24 for receiving the stud positioning 20, on the one hand, and for the passage of the screw fixing, on the other hand, like those, if any, of openings 32 in the headrest 6 allowing the crimping of the fixing lugs 31, being determined from the end free 26, traceable, from this headrest 6, these openings 23 and 32 and this hole 24 are necessarily made later to the cutting of this headrest, preferably, by means of the same tool, therefore of the press allowing to carry out this operation.

On the other hand, the light 22 in the operating rod 7 can, it, be defined of sufficient length therefore, able to match the boss 21 of the rod exit guide 10 as soon as the cut length 33 of this rod maneuver 7 is significantly less than the distance separating said boss 21 from the free end 27, provided with connecting means 25, of the rod exit guide 10. In done, this is usually the case starting from lengths cremone bolt or bolt lock 1.

However, once again, it should be noted that to the extent that the operating rod 7 can be cut, regardless of the headrest 6, it is possible to produce the light 22 in this operating rod 7 at the very moment of coming to cross this last, using the same tool.

Finally, through a rod exit guide 10, according to the invention, not only is the possibility given the carpenter to adjust, individually, rod and headrest a bolt or bolt-lock, but, in addition, the assembly of the latter and its mounting on a carpentry is found ease. In addition, it will be noted that, compared to known rod exit guides, the one according to the invention has the advantage of not creating any bulk in rebate of the opening frame.

• réduction des pièces au montage et à l'assemblage de la crémone ou crémone-serrure ;
• mise à projet de l'élasticité de tringle et/ou de la mobilité latérale de cette dernière pour une mise à longueur distincte entre tringle et têtière ;
• réduction substantielle du stock de gammes de crémones recoupables ;
• les mises à longueur, quoique différentes sur une têtière et une tringle peuvent toujours se faire simultanément avec un outil approprié ;
• l'invention n'empêche en rien une mise à longueur identique d'une tringle et d'une têtière en cas de besoins.

To summarize, the advantages arising from the present invention are:

• reduction of parts in the assembly and assembly of the cremone bolt or bolt lock;
• planning of the elasticity of the rod and / or the lateral mobility of the latter for a different length between the rod and the headrest;
• substantial reduction in the stock of ranges of cremone bolts that can be cut;
• length cuts, although different on a headrest and a rod can always be done simultaneously with an appropriate tool;
• the invention does not in any way prevent an identical length of a rod and a headrest if necessary.

Thus, the present invention makes it possible to respond, advantageously, to the problem encountered within the framework of the state of the technique, so that it represents a clear progress, especially for carpenters who see, at through this invention, the possibility of adapting, with a very great ease and perfect precision, their cremone bolt or lock-bolt.
