Definitions

• the invention relates to a device for fixing and guiding the ends of a fitting of the cremone bolt or cremone bolt type capable of fitting into a groove made in the rebate of an opening frame of a door, window or the like, said device being intended to be secured to the rear of a headrest using appropriate means and comprising means for holding and guiding an operating rod relative to said headrest and a guide stud of at least one screw fixing coming through an opening provided for this purpose in this headrest.
• a device of this kind is described, for example, in the document FR-A-2,747,723.
• the present invention will find its application in the field of building hardware and relates, more particularly, to the locking fittings, of the lever type or the bolt lock.
• cremone bolts or bolts-locks usually include a central control mechanism, housed in a housing above and / or below which rods of operation extend, the displacement of which by the through said control mechanism, is passed on to locking members, such as rollers, bits or the like. It is also frequent that the free ends of these operating rods also act, like locking members, to cooperate, in the locked position, with appropriate strikes.
• the aforementioned elements of a bolt or bolt lock take position in a recessed groove formed in the rebate of an opening, door, window or the like and are sheltered by means of a headrest coming from close said groove.
• such a headrest includes orifices for the passage of fixing screws making it possible to make the assembly integral with the joinery.
• an operating rod has, for its part, oblong slots allowing the passage of these fixing screws, without however preventing their movement between in particular a locking position and an unlocking position.

• This rod exit guide is also provided with a wing extending parallel to said base while covering, on the external side, the end portion of the rod, while a guide strip extends between the base and the wing and has a through opening adapted to the passage of the end of this rod.
• the base also has an orifice for the passage of a fixing screw located beyond the wing in order to be accessible.
• the rod it also has an orifice allowing the passage of this screw and the fixing tool when the cremone bolt is placed on the opening.
• this rod exit guide is particularly suitable for a cremone bolt provided with a rod of particular configuration and devoid, moreover, of a headrest.
• this screw guide only provides basic guidance of the operating rod relative to the headrest. In addition, it can be the cause of an incorrect operation of the cremone bolt or cremone bolt, especially when this is subject to automated removal from a joinery.
• the guide function of the fixing screw is ensured by means of a guide stud adjusted to the transverse width of the oblong slot in the operating rod and has an opening for the passage of said fixing screw.
• this guide pad often receives means allowing its riveting at the level of the headrest.
• the width of the oblong opening made in the latter for the passage of a fixing screw is also necessarily reduced, often barely greater than the diameter of said screw. fixation.
• the orifice made in the guide stud and whose section is necessarily adapted creates, at the longitudinal sides of this stud of the openings, in the sense that there is absence of surfaces for the guide of the fixing screw.
• the present invention is intended to respond to the aforementioned problems through a fixing and guiding device which is not only capable of ensuring perfect retention of the end of a rod maneuver intended to define a locking member but, in addition, to contribute to the connection and guidance of an operating rod relative to the headrest which houses it.
• this device is intended to fulfill the functions of a screw guide insofar as it can receive, in addition, at least one fixing screw intended to rigidly and securely fix the assembly in a groove provided for this purpose in the opening frame.
• the invention is intended to provide a solution to the various constraints linked to an automated mounting of a locking fitting on a joinery.
• the fixing screw for passing through the guide stud necessarily passes through an opening of suitable section made in the bottom of the first channel. Also, this opening, of strictly circular section, is capable of ensuring perfect guidance of this fixing screw.
• the upper edge of the parallel walls of the second channel can receive fixing and / or positioning lugs relative to the headrest on the rear face of which they come to bear.
• the present invention relates to the field of locking fittings, of the cremone bolt or cremone bolt type, which, under the influence of a control mechanism housed in a central housing 1 make it possible to communicate a movement to operating rods 2 extending above and / or below this housing, such operating rods 2 coming to reflect their movement on locking members, such as rollers, bits or like.
• cremone bolt or cremone bolt takes position in a recessed groove provided for this purpose in the rebate of an opening, door, window or the like, groove in which it is sheltered by means of a headrest 3 of which can be made integral with the housing 1.
• the invention relates, more particularly, to a device 4 for fixing and guiding provided capable of being attached to the rear and to one end of the headrest 3 by appropriate means 5, in particular by riveting.
• This device 4 is intended to contribute, on the one hand, to maintaining and guiding the operating rod 2 relative to this headrest 3 and, on the other hand, to guiding a fixing screw coming through an opening 6 in the latter to come and stay at the bottom of the groove and thus make the assembly integral with the joinery.
• this device 4 comprises, at least, means 7 for holding and guiding an operating rod 2 and a guide stud 8 of at least one fixing screw, this guide stud 8 extending to right of the opening 6, behind the headrest 3.
• the operating rod 2 has, for its part, an oblong opening 9 sized to allow the passage of this guide stud 8 while allowing axial movement of the operating rod 2 to allow it to move from its locked position to its unlocked position and vice versa.
• the oblong opening 9 made in the latter also has a small cross section in width.
• the guide pad 8 cannot have a thickness 10 which is barely adjusted to the section 11 of the screw of fixation. Under these conditions the perforation 12 present in this guide stud 8 for the passage of this fixing screw, generates, on the longitudinal sides 13, 14 of said stud 8, interruptions 15 of the guide surface of the screw.
• the device 4 is in the form of a profile 16 defining a first channel 17 of "U" section having a bottom 18 intended to come into contact with the rear face 19 of the headrest 3 and from which s 'extend, perpendicularly, two parallel walls 20, 21 between which is able to slide the operating rod 2.
• this profile 16 defines a second channel 22 of “U” section, also comprising two parallel walls 23, 24 corresponding substantially to the extension of the walls 20, 21 and, between which takes position, there again, the operating rod 2.
• these parallel walls 23, 24 come, in this case, to bear, at the height of their upper edge 25, on the rear face 19 of the headrest 3, while the bottom 26 from which they extend traps, with the headrest 3, the operating rod 2.
• the operating rod 2 is perfectly axially guided. It is also well maintained relative to the headrest 3 through the bottom 26 corresponding to the second channel 22.
• the opening 6 in the headrest 3 communicates with the guide stud 8 through an orifice 27 of section adapted to that 11 of the fixing screw.

• the passage opening 27 for the fixing screw in this bottom 18 of the first channel 17 can open out through a positioning pad 30, at this side 29 of said bottom 18.
• This positioning pad 30 comprises a thickness substantially equal to that of the headrest 3, which then comprises an opening 6 adjusted to the section of this stud 30.
• Such a feature makes it possible to perform in this positioning pad 30 a milling 31 for receiving the head of the fixing screw.
• a milling 31 for receiving the head of the fixing screw.
• such a design greatly facilitates the production by stamping of the headrest 3. Indeed, the latter is brought to undergo, usually, significant deformations when it is necessary to print there a orifice with frustoconical mouth .
