Description

Title of the invention: "Modular espagnolette" FIELD OF INVENTION

[0001] The present invention relates to a modular espagnolette. STATE OF THE ART

[0002] We already know of an espagnolette fitting the shutters of a bay and allowing their closed position to be locked with the support of the shutters against the front of a high or low stop attached to the bay and the tilting of the fingers attached to the two ends of the operating rod of the espagnolette, against the back of the stops, the rod being pivoted by the handle coming into a fork-shaped support carried by the other shutter in the closed position to lock the shutters in the bay.

[0003] PURPOSE OF THE INVENTION

[0004] The present invention aims to develop a espagnolette that is simpler to manufacture and more adaptable to the different characteristics of shutters.

[0005] DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0006] To this end, the invention relates to a espagnolette of the type defined above, characterized in that it comprises:

[0007] - a modular body having a head whose passage is traversed by the rod of operation and an extension with a transverse axis pivot carrying a modular handle to rotate the operating rod between the open and closed positions of the espagnolette, around the axis of the rod,

[0008] - the modular handle pivoting around its pivot to engage or disengage of a modular support,

[0009] the modular body or the modular handle or the modular tips are segments of profiles, with an axis parallel to the axis of the operating rod.

[0010] The invention as defined above considerably simplifies the manufacture of espagnolettes and their adaptation to the requirements of the buildings to be equipped, since the main components of the espagnolette are profile segments whose cross-sections reproduce the functional characteristics. This allows the components to be manufactured as profile sections with practically their final technical functions, requiring only very minor machining such as drilling, tapping, or simply cutting the component from the corresponding profile. This transfer of functions from components traditionally manufactured as injection-molded parts also makes it possible to improve the technical characteristics of the components for better integration and adaptation. to the shutters and the specifications of the shutters which themselves can be made of profiles.

[0011] The modular body of the espagnolette also allows a very wide variety of component combinations.

[0012] The simplification of manufacturing stems from the design of the profile sections which allows for better consideration of the mechanical characteristics of material strength and optimization of the functions integrated into the profiles.

[0013] In addition, modular components simplify the problems of possible reuse and renovation by replacing one or another modular component in a espagnolette.

[0014] From an economic point of view, the manufacture of the espagnolette is thus moved from the injection molding of components to simple finishing and assembly operations.

[0015] According to another characteristic, the modular body profile has a cross-section comprising:

[0016] * a cylindrical part forming a passage with a smooth rotation surface which would correspond to the groove in the stem and,

[0017] * an extension forming at least one branch carrying the pivot of the handle.

[0018] The modular body allows it to integrate functions other than that of a A simple pivot allows for the mechanical advantages of a rigid three-dimensional structure (the profile or profile segment) and the lightweight design adapted to this type of operation, as well as the integration of a handle. This enables the integration of safety features through a simple locking mechanism that is nonetheless difficult to access from the outside.

[0019] According to another feature, the extension of the modular body has two branches whose facing, parallel faces form a guide and holding interval for the modular handle and

[0020] - one of the branches has a pivot formed by the circular cylindrical head of a screw whose The threaded rod is screwed into the inner face of one of the arms and defines the axis of the modular handle.

[0021] - the other branch has an access window to the screw head,

[0022] - the modular handle having one side whose end comes into the gap with a drilling of diameter corresponding to that of the screw head to pivot around it with the modular handle.

[0023] This modular structure allows the articulation of the handle on the body to be carried out in a very simple and efficient way for the holding of the handle and the rigidity of this body / handle combination between the operating rod and the support receiving the handle.

[0024] According to another feature, the outer face of the branch with the pivot on its inner face is recessed to receive the other side of the modular handle as a support and guide.

[0025] The withdrawal, besides facilitating the realization of the pivot, allows the handle to be guided and held rigidly in the closed position, in the contour of the body profile and the engagement in the support for a continuity of the lateral surface of the body / handle assembly which is also interesting for the finish of the espagnolette in the closed position of the shutters, visible then from the inside of the room.

[0026] According to another characteristic, the modular handle is a profile segment having:

[0027] - two sides connected by a crossbar set back from the end of both sides, of which

[0028] * the end of one side beyond the cross member has a bore engaged on the pivot and coming in the interval

[0029] * the other side comes against the other face of the branch bearing the pivot,

[0030] - a gripping element connecting the other end of the sides forming a rotated relief towards the plane of the shutters and arriving substantially in this plane when the handle is engaged in the modular support.

[0031] This handle structure is very rigid, transversely while being light; it reduces the gap between the handle and the plane of the shutters, and even allows the handle to be supported against an external push exerted on the shutters either by natural elements (wind) or malicious pushes.

[0032] According to another advantageous feature, the modular tip is a profile segment whose cross-section has a cylindrical part to form the sleeve and an extension with a straight side to form the finger and its bearing surface,

[0033] * a screw hole being machined in the sleeve opening into the rib for secure the tip at the end of the rod with a screw.

[0034] This simple and effective tip structure contributes to the overall effect of solidity, rigidity of the espagnolette's hold and simplification of its manufacture and installation.

[0035] According to another feature, the support is a profile segment with an H-shaped cross-section constituting an H-shaped skeleton, one branch of which is the application branch for fixing to the shutter and the other branch forms a tooth defining, with the first branch, the open interval of the fork formed by the support,

[0036] * this second side extending to form a grip under the crossbar connecting the two branches, the space between the two branches receiving the handle, and

[0037] - the skeleton receiving a glove covering the end of the two branches.

[0038] This simple modular form, obtained by the section of a profile, allows several functionalities of use to be combined with the strength and resistance of a three-dimensional structural piece.

[0039] According to another feature, the modular body has a head that is free in translation and rotation relative to the operating rod passing through its passage. This head is connected to the rod by a wedge freely interposed between the surface of the passage and the surface of the operating rod to allow adjustment of the head and to be forcibly engaged between the surface of the passage and that of the operating rod, locking the head onto the rod in the adjusted position of the body carrying the handle and comprising

[0040] - a tapping in the passage,

[0041] - a threaded sleeve through which the operating rod is screwed into the thread from the head to forcefully engage the wedge in the gap between the passage and the rod and to secure the body in rotation and translation on the operating rod.

[0042] This modular body allows the indexing of the body and the handle to be adapted to different thicknesses of stops in bays which may be encountered, for example, on renovation sites.

[0043] In particular, in the case of a espagnolette whose wedge has an axial rib of complementary shape to the section of the groove of the rod and in relief of its surface coming against the operating rod to engage in its groove and be rotationally fixed to the operating rod.

[0044] The wedge remains locked in rotation relative to the passage, which promotes its gripping and the effectiveness of the clamping, and this is all the more effective if the passage of the head has, in order along the axis:

[0045] - an inlet with a threaded hole larger in cross-section than the cross-section of the rod maneuver,

[0046] - an inverted frustoconical surface joining

[0047] - a cylindrical surface corresponding to the cross-section of the operating rod,

[0048] and the threaded sleeve has

[0049] - a cylindrical inner surface corresponding to that of the operating rod,

[0050] - a smooth cylindrical end beyond the thread to bear against the wedge and

[0051] - a screwing collar for screwing the threaded sleeve into the tapping.

[0052] According to one variant, the head is completed by a cylindrical insert coming into the passage of the head which is cylindrical, smooth, and equipped with an axial groove and

[0053] - the cylindrical insert has a rib for engaging in the axial groove and a a collar to rest against the underside of the head, and

[0054] the inner surface of the head comprising

[0055] * a tapped hole to receive the threaded sleeve) and terminated by

[0056] * a smooth crown and after this

[0057] * an inverted frustoconical surface to receive the wedge, in particular the ring.

[0058] The addition of the insert simplifies manufacturing because it avoids machining the passage of the head coming from the profile which has the shape of the section of the profile and transfers the functions integrated in the head onto the inner surface of the insert.

[0071] DESCRIPTION OF EMBODIMENT METHODS

[0072] Figure 1 is an isometric view of a modular espagnolette 100, according to the invention, comprising an operating rod 1 with a longitudinal groove generally located on the "rear" side, facing the shutter when the espagnolette 100 is in the closed position. The rod 1 terminates at its ends in two modular end pieces 2 fitted onto the ends of the rod and rotationally fixed to it by their rib 323 which fits into the groove 11 of the rod. The end pieces 2, formed of a sleeve 21 and a finger 22, have their upper surfaces closed by a cap 23. A hole 211 in the end pieces 2 allows them to be locked into the groove 11 of the tube 1 by a screw.

[0073] The rod 1 is held against the flap at a short distance by a modular collar 6, upper and a modular collar 6, lower as well as an intermediate collar 6.

[0074] In this intermediate position, the rod 1 carries the body 3 and the handle 4 in the closed position, in the horizontal alignment of the body 3; the rod is engaged in a fork-shaped support 5, fixed to the other flap.

[0075] The shapes of the modular body 3 and the modular handle 4 appear in the enlarged view of [Fig.2] and in the horizontal sections (perpendicular to the axis ZZ) of the rod in the position of [Fig.2]; these sections are represented in parts A and B of [Fig.3], they correspond respectively to a plane passing through the pivot of the handle and a plane parallel and above it.

[0076] The body 3 is a profile segment of section 303 ([Fig.4] part A) composed of a cylindrical part 3030 and an extension 3036 with a relief 3011 in the circular opening of the cylindrical part to form a rib which engages with the groove 11 of the rod 1.

[0077] The cut slice of the section profile 303 shown is the modular body 3 to be machined by a few simple operations.

[0078] The extension 3036 of the section forms the two branches 361, 362 of the modular body; these branches are separated by a gap 363 receiving the end of a blade-shaped side 41 of the modular handle 4 to hold this end and guide it by the pivot 32; the pivot is formed by a cylindrical head screw 321, screwed by its threaded rod 322 into a tapped hole 3611 of the branch 361 along the axis (uu) which is the axis of the pivot.

[0079] The pivot 32 is put in place through a window 3621 of dimensions compatible with the arm 362. This window preferably has a hole with a diameter slightly larger than that of the screw head.

[0080] The side 41 of the handle has a bore 411 of diameter corresponding to that of the head 321 forming a bearing; the assembly of the handle 4 to the body 3 is done by aligning the bore 411 on the axis (uu) of the tapped hole 3611 and then screwing the pivot 32 through the window 3621.

[0081] The modular handle 4 is thus held and guided around the pivot 32 in the interval 363 by the contact surfaces of the faces of the branches 361, 362 with the faces of the blade constituted by the side 41.

[0082] According to figures 1 and 2, the arm 361 has a rounded end in an arc of a circle centered on the axis (uu) of the pivot 32 to take into account the particular shape of the handle 4 and reduce its bulk at the pivot.

[0083] In more detail, according to figures 2 and 3, the handle 4 is composed of two sides 41, 42 in the form of blades, connected by a crossbar 43 leaving between them an interval 44 and ending with a gripping element 45 with a relief 451 on the flap side, connecting the two other ends of the sides 41, 42.

[0084] The modular handle 4 engages by its sides 41, 42 and its gap 44 in and around the modular support 5 in the shape of a fork, represented only in section in the two parts of [Fig.3].

[0085] The arm 41 engages in the gap 53 between the application side 51 of the modular support 5 and its tooth 52; the arm 42 engages on the outer side of the tooth 52.

[0086] The modular handle 4 is a slice of profile with a cross-section of 304 according to [Fig.4] part B. From this profile, the modular handle 4 is obtained directly, which only needs to be completed by the drilling 411 forming the bearing and that of the fixing of a push button 452 on the relief 451, facing the shutter.

[0087] Side 41 is held on the pivot 32 in the gap 363 occupied by the head 321 of the pivot. This head 321 may have sufficient height to remain partially engaged in the window 3621 without, however, protruding from it, thus reinforcing the hold of side 4L

[0088] The thickness of the arm 361 carrying the pivot 32 is increased compared to that of the arm 362 in order to have a sufficiently long thread without this thread protruding from the other face of the arm 361, turned towards the other side 42 of the handle.

[0089] According to the cross-sectional view of [Fig. 3] part A, the end of the arm 362, with its outer face turned towards the flap, has a push button 3622, just as the relief 451 has a push button 452, to mitigate any contact between these two parts 362 and 451 against the flaps and to dampen, where applicable, noise and friction during handling. The plane 102 of the flaps is shown in [Fig. 3] part A.

[0090] The modular end caps 2 are obtained from a profile having cross-section 302 ([Fig. 6] part A) which combines a cylindrical portion 3021 with a cylindrical orifice having a relief 3323 and an extension 3022. The profile segment obtained from the cross-section 302 forms the sleeve 21 with the cylindrical portion 3021 and the rib 323 via the relief 3323 of the cross-section. This rib 323 acts as a key to cooperate with the groove 11 of the operating rod 1.

[0091] The extension 3022 of the section with a straight side provides the blank for the end piece 2 ([Fig. 6] part AA), the machining of which is limited to a tapped hole 211 for a screw, locking the end piece 2 onto the end of the operating rod 1. The face 221 of the finger 22 is flat so as to lie flat against the stop fitted to the opening closed by the shutters. The end piece 2 is reversible in shape since it is through-hole, so that it can be used as both an upper and a lower end piece.

[0092] The modular support 5 according to [Fig.5] part AA is also a profile segment of section 305 in the shape of H, the side 51 of which is the fixing plate of the support 5 to the shutter and the other side forms the tooth 52 delimiting the interval 53 receiving the side 42 of the handle 4; the interval 44 of the handle 4 engaging on the tooth 52.

[0093] This tooth 52 has an upper end 521 forming a retaining hook, which covers the side 42 of the handle 4 which also rests on a shoulder 522 at the bottom of the gap 53 so as to hold tightly the side 42 of the handle whose gripping element 45 corresponds to the end of the handle 4 beyond the part coming into the support 5.

[0094] To dampen noise, the support 5 is capped with a glove having the shape of the upper half of the skeleton 50 of the support 5, coming into contact with the handle 4.

[0095] The skeleton 50 of the support 5 is a slice of profile with a cross-section of 305 according to [Fig.5] part B. This slice with an H cross-section has two branches 5511 and 5512 forming the two teeth 511 and 512 of the skeleton 50.

[0096] The arm 511 extends along the entire height of the support 5 to fit snugly against the shutter to which the arm is screwed. The arm 511 is connected to the arm 512 by a cross member 513. The upper end of the arm 511, as well as the cross member 513, is drilled with holes 541 and 542 for the screws securing the support. The arm 512 is truncated to allow access to the holes 542. The arm 512 is extended and offset beyond the cross member 513 to form a grip 514 for grasping and holding the shutter to which this support 5 is attached, thus facilitating the engagement of the handle in the support 5.

[0097] The skeleton 50 of the support 5 requires machining only the two holes 541, 542 and then the fitting of the glove once the skeleton is fixed to the flap. The glove completes the shape of the second tooth with its end 521 ([Fig.5] part AA).

[0098] A variant 5' of the support simplifies the shape of the second tooth 52' of the glove, the skeleton 50 being the same with the same references, supplemented by (') without being redrawn ([Fig.5] part AC).

[0099] According to parts BB, BB' of [Fig. 6], the open collars 6 are also obtained as a slice of a cross-section profile 306 according to part B of [Fig. 6] with a cylindrical passage 61 closed over more than half its perimeter to retain the rod 1. The branches 62 are simply drilled for the screws for fixing the shutters with countersunks 621 to conceal the heads of the fixing screws.

[0100] The offset collars 6' are obtained from the section profile 306' of [Fig.6] part C; this collar 6' consists of a sleeve 63' extended by a tab 64'. The collars 6' are machined with a counterbore 641' to have a tab of the same thickness for both screwing points to standardize the screws and also to conceal their heads.

[0101] Another embodiment of the modular espagnolette 100, the representation of which in figures 7 and 8 is limited to the assembly of the body 3 and the handle 4 on the operating rod 1, comprises a solid or tubular rod in both cases of circular section or similar to a circular section with a hollow deformation of the section constituting a groove 11 to secure in rotation the modular ends 2 and the modular handle 4 via the modular body 3 on the rod 1.

[0102] The body 3 has a partially cylindrical head 31 to pivot with the rod 1 without encountering the surface of the flap against which the rod 1 is held with a gap reduced to a minimum for the freedom of pivoting.

[0103] The head 31 is drilled with a passage 30 with a thread 312 of diameter greater than that of the rod 1 to receive the threaded sleeve 34. The thread 312 continues with an inverted frustoconical surface 313 whose radius decreases to a cylindrical edge 314 adapted to the cross-section of the rod 1. This edge 314 is continuous, without any particular relief so that this part of the body in contact with the rod 1 is free to rotate relative to the rod 1 on which it is engaged.

[0104] The head 31 is completed by a wedge in the form of a split ring 33, conical (outer surface) and cylindrical (inner surface). The inner surface of the ring 33 is provided with an axial rib with a cross-section complementary to that of the groove 11 of the operating rod 1, thus securing the ring 33 against the rod 1 in rotation.

[0105] The conicity of the split ring 33 corresponds to that of the frustoconical surface 313 in which it engages.

[0106] The threaded sleeve 34 has a notched collar 3421 above its thread 341 which screws into the tapped hole 312.

[0107] The threaded start 341 is preceded by an unthreaded ring 343 with a smooth edge, designed to bear against, without catching, the top 332 of the split ring 33 and to engage in the remaining gap between the frustoconical surface 313 and the rod 1. This engagement is achieved by pressing against the top of the split ring 33 to compress it within the gap and secure the body 3 to the rod 1 in the set position. The inner diameter of the threaded sleeve 34 is, within clearance, that of the operating rod 1, allowing it to slide along the rod.

[0108] The [Fig.9] part A shows section 303 of a profile in which the slice forming the modular body 3 is cut.

[0109] Section 303 consists of a circular cylindrical head part 3031 with a passage 3030 and an extension 3036 forming the two arms of the support.

[0110] The modular support 3 obtained from the section profile 303 is shown in the two isometric views of parts AA and AA' of [Fig.9].

[0111] The body 3 has a cylindrical head 31 with a passage whose entrance reveals the thread 312.

[0112] The arm 362 is provided with a window in the form of a hole 3621, machined in the axis (uu) of the pivot; this window allows the tapping to be drilled in the corresponding face of the other arm 361 as has already been described.

[0113] The installation of the modular body 3 on the rod 1 is done by the untightened pre-assembly of the components of the head 31 on the operating rod 1 and the placement of the upper and lower tips 2 which are rotationally secured to the rod 1.

[0114] The clamps 6 for securing the operating rod 1 are threaded onto the rod 1 if they are closed or if they do not open sufficiently to be clipped onto the operating rod 1. The clamps 6 are fixed to hold the rod 1 close to the end caps 2 and close to the body 3, preferably underneath it, slightly away from the surface of the shutter so as not to hinder the movement of the operating rod 1. The modular espagnolette 100 is installed by securing the operating rod 1 with its clamps 6 and the support 5, then adjusting the body 3 along the operating rod 1 and orienting it appropriately relative to the operating rod 1 so that the fingers 22 of the end caps 2 are firmly pressed against the stops and the handle 4 can fit into the support 5.The tightening in the set position is achieved by the threaded sleeve 34 bearing on the split ring 33 which remains rotationally fixed to the rod 1 and locks into the frustoconical surface 313 of the body 3, locking the latter in this position on the rod 1. Tightening is preferably done with a wrench 8 of the type used for fire hose couplings, hooking into the notches 3421 of the collar 342 to screw the sleeve.

[0115] According to figures 7 and 8, the head 31 of the body 3 continues with two branches, of which the branch 362 is shown, carrying and guiding the handle 4 by means of a pivot 32 outlined by its axis (uu).

[0116] The modular handle 4 has the same shape as that described previously.

[0117] Figure 10 shows another embodiment 100a of a modular espagnolette according to the invention, the schematic representation of which is limited to the portion of the modular body 3a at the junction of the operating rod 1a and the connection of the handle 4a to the body 3a. The components of this modular espagnolette 100a are identical or analogous to those of the first embodiment 100 bear the same numerical references, completed by the suffix (a) and not all will be described again.

[0118] The operating rod la is a solid or tubular rod with a circular or possibly polygonal cross-section with facets, reduced to allow it to pivot freely in the housings of the collars fixing the operating rod la freely in rotation to the shutter. It has a longitudinal groove lia.

[0119] The body 3a is secured in axial position and in oriented position, adjusted, indexed by its head 31a, to the rod la by a tight connection via a wedge in the form of a split ring 33a in a manner analogous to the connection of the previous embodiment but with interposition of an insert 35a, reproducing the structure of the head 31 of embodiment 100.

[0120] The cylindrical head 31a has a passage 30a with a smooth cylindrical inner surface 311a, provided with an axial groove 315a (direction ZZ). The cylindrical surface 311a receives a sleeve-shaped insert 35a with a smooth cylindrical outer surface 351a.

[0121] The outside diameter of the insert 35a corresponds to the diameter of the surface 311a to engage in it by a tight fit, the rib 355a coming into the axial groove 315a of the cylindrical surface 31 la and its collar 356a bearing against the underside of the head 31a; the inside diameter of the thread 352a of the insert 35a is greater than the diameter of the operating rod la.

[0122] The inner surface of the insert 35a consists of an inlet with a threaded hole 352a, ending in a smooth ring 3521a. This ring 3521a continues into an inverted frustoconical surface 353a, of decreasing diameter to join a cylindrical edge 354a, of diameter adjusted to that of the operating rod la so as to be able to slide on it.

[0123] This inner surface of the insert 35a is a replica of the inner surface of the head 31 of the body 3 of the first embodiment; in other words, the head 31 of embodiment 100 transfers its functions to the insert 35a, which is rotationally fixed to the head 31a by its rib 355a coming into the axial groove 315a of the head 31a. This groove 315a is advantageously located in the thick part of the head 31a at the base of the arm 362a ([Fig. 10]).

[0124] The locking of the body 3a onto the operating rod la is achieved as before by a split ring 33a, which acts as a wedge and is engaged in the inverted frustoconical surface 353a of the insert 35a and compressed by the threaded sleeve 34a. This compression simultaneously results in the locking of the insert 35a against the cylindrical surface 31 la of the head 31a and the locking of the insert 35a against the split ring 33a, itself prevented from rotating relative to the operating rod la by the engagement of its rib in the groove 1 la of the rod la. Thus, the body 3a is locked on the rod in the adjusted orientation, chosen according to the support of the tips 2 against the stops of the bay and the position of the support, not shown receiving the handle 4a.

[0125] This angular position of the handle 4a is not predefined but chosen on the site according to the installation to be carried out.

[0126] According to [Fig. 10], the modular body 3a carries the handle via the pivot, schematically represented by its transverse axis (uu), which is supported by the two arms, receiving and guiding the end of the handle between them. In the closed position, the handle is housed in the support (not shown). This modular espagnolette 100a thus consists of the rod la, the modular body 3a, the modular handle 4a, the modular support, and the modular end caps and stops, these latter elements not being shown.
