Description

ASSISTANCE DEVICE FOR CLOSING AND OPENING, MOBILE LEAF, SLIDING LEAF

The invention relates to the fields of equipment fittings for enclosed structures by at least one mobile leaf, at least one of whose functions is sliding. More particularly fittings preserving the risks of inappropriate maneuvers of a leaf by a user.

The invention applies to immovable construction works just as much as to furnishing works without however being limited thereto; thus, for example, the invention can be applied to access or partitioning equipment in means of transport. For example in real estate products, these are doors, windows and or patio doors of construction known to have one or more opening functions such as French, tilt and turn and more particularly for the invention at least that of sliding. For movable goods, these are sliding furniture doors or leaves such as dressing doors, for example. In public transport, for example, the invention can be fitted to movable sliding partitions or even sliding accesses.

Whatever the work concerned, the partitioning or enclosed works comprise a fixed frame integrated into the work or attached to the work, and at least one opening frame, mobile leaf, mobile, here for the invention at least sliding , secured by fittings in the fixed frame. More particularly, a fixed frame can be equipped with multiple sliding covering frames and constitute all or part of a partition of a movable or immovable structure.

All too often, inadvertent or clumsy manipulations of sliding leaves cause malfunctions or even the inability of the leaf to perform its sliding function. Sometimes, in combination or separately, the weight of the leaf or the weak resistance of the structures of the fixed or opening frames, despite correct handling, can generate identical risks. In short, it is the static and dynamic performance and the endurance performance that are undermined. As a non-limiting example, the excessive speed of a heavy leaf during the opening or closing maneuver will cause the opening frame to bounce on the fixed frame. The impact of the respective uprights of these frames permanently and irreparably affects fittings such as locking members such as strikers and locking elements. But these shocks affect just as much the fittings of the crosspieces of these frames which comprise the sliding elements such as rails and rollers. These shocks ultimately can affect the very structures of these frames and more particularly firstly that of the frame of the opening leaf breaking the squareness and the parallelisms of the opening frame with the fixed frame.

For each known cause, the state of the art has found permanent but palliative individual solutions. The state of the art responds to a specific problem without however being able to resolve all the risks, at least those major ones and causes of the malfunctions and partial destruction of sliding door leaves as described. These devices are, for example, simple or complex shock absorbers which avoid the rebound or the shock of the uprights of the frame of the casement leaves against the uprights of the fixed frames such as bumpers, buffers, at the end of their travels or hydraulic or mechanical shock absorbers. For control of strokes when opening or closing sliding sashes, there are door closer devices but which are not suitable for sliding sash functions. In addition, they all have the disadvantage of taking up space and require reducing the glazed surface in the case of windows and French windows. Sometimes they harm the aesthetics of the work. It should be noted that the state of the art has not succeeded in solving the opening aid other than with electric motorized means.

The object of the invention is to solve all of these drawbacks by designing a closing and opening assistance device for mobile leaves of sliding openings, invisible due to its reduced volume and taking advantage of the structures and structural rabbets of the fixed and sash frames. The invention mainly takes advantage of the interaction of the upper crosspiece of the fixed frame equipped with a profiled rail and of at least one of the side uprights of the opening frame of the leaf. This permanent interaction makes it possible both to design a damping and closing assistance solution, a controlled assistance solution at the opening of a sliding sash, or even to ensure the initial positioning of permanent closing of the sliding sash frames in between. The means implemented by the invention make it possible to gradually but surely absorb all the kinetic energy during the opening maneuver for example and to store it gradually, to store it intact in order to restore it later during the opening maneuver. closing the sash, for example. The invention is reversible with right-left reversibility and high-low reversibility. The invention can be used simultaneously at each of the ends of the uprights of the opening frame of a sliding door and in connection with each of the ends of the upper and lower crosspieces of the fixed frame by assuming symmetry functions appropriate to the maneuver undertaken. In the case of sliding inserts, the invention can be used in the same way for each leaf with this feature that the reference of these sliding leaves will not be an amount but a closed position reference point on the crosspieces, high and low. , of the fixed frame. For these purposes, it suffices to orient and position the devices in such a way that they perform the same functions at the ends of the same upright or reference point and inverse functions at the ends of the opposite upright of the opening frame. The invention ensures the avoidance of risks with a single application of the device but allows with multiple applications to ensure these same advantages for sliding sashes of greater mass, even for multiple sliding sashes, without it being necessary to modify and design and components of the invention.

For this purpose, the device for assisting with closing and opening, of mobile leaves of sliding openings of construction works, of access or partitioning in transport, of furniture products, is characterized by a compact device frame crosspiece of universal application, to be inserted into sections or mortised or mortised on solid supports comprising a plate equipped with a rack, which at one or the other of its ends interacts by gearing with a compact sash post device, of universal application, to be inserted into sections or mortised or mortised on solid supports, comprising a motor device mounted adjustable sliding in the direction of a rack, on a plate; the two primary devices respectively equipping one end of a crosspiece of a fixed frame and an adjoining end of an upright of an opening frame of at least one leaf in the open position or at the end of the closing assistance stroke said leaf in its fixed frame.

This description of the device according to the invention implements specific means shown in the figures. It is done, without being limited thereto, for an application of the invention, front view, in the upper left corner of a French window, not shown, with two leaves, one of which is fixed on the right and a second mobile sliding to the right in the closed position.

The reference signs concerning identical means, parts, elements or objects are kept unchanged from one figure to another.

The constituent elements of the invention are shown in partial views of the right end of the upper crosspiece of the frame, starting from the right end of the guide rail which equips it and comprising elements 1, 2 of the invention. on the one hand, and on the other hand from the upper end of the corresponding upright of the sliding leaf, therefore on the right side of the mobile opening frame comprising the driving elements of the invention.

The frame rack:

The invention implements, at the end of the crosspiece described above, a plate 1 inserted into the bottom of a U-shaped guide rail, not shown, secured to the crosspiece. This plate has on one of its faces a rack 2, the length of which is capable of ensuring a useful stroke of a toothed pinion 3 and the width of which is at least equal to the thickness of said pinion 3 which, length and width, are necessary and sufficient for the operation without obstacles of the means of assistance with the closing and opening of the mobile leaf of the sliding leaf. The characteristic of this rack 2 is that one of the end teeth will always be approximately in abutment with said pinion 3 at each opening limit switch. Advantageously, the invention thus avoids free running games which can collide the faces of the teeth of the rack 2 and of the pinion 3 during the initialization of the movement of the sliding leaf. The dimensions of the plate 1 will be minimal in order to be able to be fixed and maintained integral with the U-shaped bottom of the guide rail, whatever its dimensions. The invention is independent of the plate fixing means, not shown and left to the discretion of the manufacturer. Thus designed, this universal rack plate 2 adapts to all known designs of profiled rails used by manufacturers of sliding openings.

The invention implements, at the end of the upright described above, a support plate 4 of a box 5 comprising the mechanism of motor means for assisting in opening or closing. This universal plate 4 can be inserted, larded or applied in any type of sliding leaf frame upright. In fact, its width, length and thickness dimensions are designed to take advantage of the standard or personalized rabbet sets between the uprights of the leaf and the frame. The plate 4 comprises longitudinal wings 6 shaped like a C, folded perpendicularly towards each other to form grooves for sliding and holding said casing 5 of the motor means. The method as well as the fixing means of this support plate 4, not shown and left to the discretion of the manufacturer, are independent of the invention.

The opening or closing assistance motor means comprise at least one box 5 consisting of a box 7 and a cover 8.

The invention also implements associated with the end opposite to that of the terminal pinion 3 of the housing 5, a device 9 for adjusting the position of the housing 5 in the slide 4, starting on the upright of the opening frame on the one hand, and on the other hand simultaneously constituting a device 9 for adjusting the terminal pinion 3 on those of the rack 2.

Box 5:

Said box 5 is made up of a box 7 and its cover 8 and includes the means for holding and sliding the box 10 in the support plate 4.

The means for holding and sliding the box 5 starting from the trunk 7 in the support plate 4 are formed by the outer walls 13 of the sides of the box 5, which are inserted sliding into the opening of the wings 6 in C of the plate - bracket 4; thus constituting the slide of the motor housing 5. The locking of the positioning of the motor box 5 on this plate 4 is carried out by the adjustment device 9 connected to the motor box 5.

Chest 14:

The means for securing the box 14 to the lid 8 consist of devices known to those skilled in the art such as screws, staples and harpoons made on the edges of the wings 13 of the box 5 and in correspondence with those on the edges of the lid 8 for the simultaneous positioning and juxtaposition of all the technical achievements characteristic of the internal conformations symmetry of the trunk 5 and of the lid 8. The plane of symmetry is that parallel to the sides of the trunk 14 and of the lid 8 laid sideways side by side, starting from the plane parallel to the bottom of the trunk 5 and to the internal face of the lid 8.

In these technical achievements characteristic of the internal conformations of the box 7 in addition to the driving elements, we have the means of maintaining and moving, linear or rotary, fixed and mobile driving elements in the box 7 consisting of openings for the passage of screws and nuts 22 , grooves of translational guide recesses 23 of a slider 24, which grooves are of length at least equal to or corresponding to the opening stroke of the rack 2 indicated above, of four tenons, three of which have a nut function forming axes of the pinions 3, 19, 20 of the gear 21 and of which the fourth 25 constitutes the fixed positioning of the means of accumulation and storage 26 of the kinetic energy of the movements of the leaf. The drive elements of the trunk 7 consist of a gear 21 of three consecutive pinions 3, 19, 20, two of which 3, 20 are integral in rotation with a rack 27 of a slider 24, one of which 3 interacts with the rack 2. pinions 3, 2 at the end of the gear 21 are aligned on a substantially median longitudinal axis parallel to the sides 13 of the housing, while the axis of the satellite intermediate pinion 19 of the other two 3, 20 is offset so as not to interact with the rack 27 of the slider 24 and again to allow adjustment of the rotational strokes to that of the initializations of the leaf opening movements. The positioning and size of the gear 21a was solved by a suitable recess 27 in the inner side of the wall 13 on the side adjacent to the gear with the appropriate dimensions for the free rotation of the crowns of the pinions 3, 19, 20 of the gear 21. The cheeks of the toothed wheels 3, 19, 20 comprise cheeks, cylindrical reinforcements of diameters smaller than that of their respective ring gears and centered on the axes 22 of respective rotations. The diameter and the height of these flanges are substantially less than the diameter and the depth of the cylindrical recesses made in the bottom 28 of the box 7 and the opposite internal wall 29 of the cover 8 in which they fit without excessive play. The center of the cylindrical recesses of the bottom 28 of the trunk 7 each comprise a cylindrical tenon nut 22 of diameter adapted to the respective diameter of the shaft passages 22 of the pinions 3, 19, 20 to allow their rotation without excessive play. The height of a tenon 22 is greater than the total thickness of the flanges and a pinion. The maintenance of the pinions 3, 19, 20 is completed after assembly by a screw 22 through appropriate openings of the cover 8.

The slider 24 of the motor elements has the shape of an inverted H on its longitudinal central axis. The free end of the parallelepiped-shaped upper arm 30 is flush in the high position with the upper end of the gear 21 and forms a stop 31 on the body of the rack 4 plate 2 of the crosspiece of the frame. On the gear side face 21 is made a rack 32 replica of that 2 of the plate 4 of the frame so that in the high position of the slider 24 the two pinions 3, 20 terminals of the gear 21 rest on the rack 32 and in low position of the slider 24, only the lower pinion 20 rests on the upper end of the rack 32 of the slider 24. two by two of the shaped side guides 33 and of dimensions, thickness and width, slightly less than the dimensions of the longitudinal recesses 23 made respectively in the bottom 28 of the box 7 and in the inner face 29 of the lid and here recess 23 positioned on the side opposite to the gear 21. The length of this longitudinal recess 23 is at least equal to the stroke of the pinions 3, 19, 20 on the rack 32 starting from the stroke of the upper pinion 3 on the rack 2 of the p latin 4 on the frame. The width of the body of the slider 32 supplemented by the height of the side guides 33 is adjusted to the interval between the funds of the aforementioned recesses of the bottom 28 of the trunk and the funds of the aforementioned recesses of the internal wall 29 of the lid 8 fitted to the trunk 7.

The bottom of the inverted H shape forms a fork 34, one arm 35 of which is consecutive to and integral with the upper arm 30 of the inverted H with its longitudinal plane slightly offset from that of the latter and towards the median longitudinal plane of the fork. Its upper end 35 secured to the upper arm 30 of the inverted H takes advantage of the guide finger 33 of the latter in its sliding so that only its lower end 35 requires on its sides 35 facing the bottom of the trunk 7 and the internal face of the cover. 8 a stud 37 of cylindrical guide of height and diameter identical to the height and width of the guides of the upper arm 33. The length of this arm 35 is substantially equal to that of the upper arm 33. The other arm 36 of the parallel inverted H to the two aforementioned 30,35 has the same dimensions and arrangements symmetrical to the arm 35 with respect to the median longitudinal axis passing through these two lower arms 35,36 except that it additionally comprises at its upper end 36 on its parallel sides at the bottom of the trunk 7 and on the inner face of the cover 8, a guide stud 38 which studs 38 are always of dimensions, height and width, identical to those of the guides 33 of the upper arm 30 so that they too i to be able to move and guide in a recess configuration with identical characteristics 23 to those other 23 practiced for the guides of the upper arm 30. The two lower arms 35, 36 of the inverted H are elastic and accept an elastic deformation spreading their free lower ends in a transverse plane of the trunk 7. The invention takes advantage of this elasticity by modifying the terminal linearity of the linear guide recesses of the arms 35, 36 which are made substantially concave towards their terminal ends. The concave curvature 39 is directed towards the median longitudinal axis of the fork 34. At the terminal end of each of these concave recesses 39, is made an obtuse angular transmission 40 directed towards the median longitudinal axis of the fork 34 which abuts the central housing 41 of the body of the cylinder 26. This reference 40 of length slightly greater than the diameter of the studs 37, 38 which move therein constitutes a ramp striker which locks the slider 24 in the low position, starting in the opening position of the leaf. The engagement of the locking of the terminal pins 37, 38 of the lower arms 35, 36 is ensured by the lower ramp of the angular transmissions 40 and by a blade spring 42 of compression, concave, its curvature housed in the concave part of the corresponding recess 23. The lower right end of this blade is partly of its end inserted between the body of the jack 26 and the wall 43 of the housing 44 of the jack 26. The end of the two blades 42 is terminated by two returns 45 forming a hook to be anchored in the recess 46 for fixing the cylinder 26 in order to ensure their immobilization. The width of the blade 42 remains identical to those of the other aforementioned parts. This recess configuration 23 for guiding the free elastic ends of the arms 35, 36 allows the maintenance of the lower position of the slider 24 locked. Unlocking is carried out using the upper ramp of the wall of said angular transmission 40 under the constraint of the force applied by the pinions 3,20 on the rack 32 during initialization of leaf closure.

The two arms 35, 36 are connected by a crosspiece 47 secured to their upper ends. This crosspiece 47 comprises abutting on its underside and centered on the median longitudinal axis between the two arms of the fork, a reservation for support and attachment of the rod 48 of the cylinder 26.

The cylinder 26, pneumatic or hydraulic, the rod 48 of which ensures a stroke identical to that of the slider 24. This rod 48 slides in the recess made between the walls opposite to each other of the recesses of the arms 35, 36 elastic of the fork. The bottom of this recess has a longitudinal slot 49 which makes it possible to observe the position of the rod head 48 of the jack 26. The width of this recess is substantially greater than the diameter of the body of the jack 26 and its length is that of the jack 26 with rod 48 fully extended. The lower end of the recess which constitutes the support for the bottom of the cylinder 26 is open to allow its fastening means 50 to emerge, represented here by a central ring allowing the passage of a pin 51 for immobilizing the body of the cylinder in translation. ram. Thus, the lower part of the box 7 has a recess in which the transmissions 45 of the ends of the spring blades 42 grip and on the bottom of which is made the anchoring pin 51 of the body of the cylinder 26 via its ring 50.

The lower outer wall of the edge of the boot 7 includes a recess forming a screw head rest for the device 9 for adjusting the position of the boot 7 on its support plate 4.

The cover 8

The cover 8 comprises, identically and symmetrically, the recesses of the securing means 15 complementary to those 14 of the trunk 7, means for holding, linear or curved displacements, complementary means for rotating the aforementioned elements of the mobile motor elements. The plane of symmetry is the longitudinal plane parallel to the longitudinal outer faces of the edges of the box 7 and of the lid 10.

The width and length dimensions as well as the geometry of the cover 8 are identical to those of the box 7.

The adjuster 9

The device 9 for adjusting the position of the casing 5 in the slide 4 comprises a reduced casing 10 of dimensions, seen in section, identical to those of the motor casing 5 but of reduced length with respect to the latter 5. This device 9 comprises the same means for holding and sliding the casing 5 allowing the device 9 to slide in the support plate 4. adjustment screw 12. The housing 10 of the device 9 comprises the means for holding a nut 11 for the adjustment screw 12, the assembly means 16 of its plate 17 and of its cover 18. The nut 11 whose light is centered on the median longitudinal axis of the case 10 is made accessible on the lower and upper sides of the case 10 by a suitable slot to allow an adjustment screw 12 to pass on either side of said lower and upper sides. Two transverse passages 52 of the lid and the base of the box 10 ensure the immobilization of the adjustment device 9 with pressure screws on the slide-support 4 allowing the rotation of the screw 10 to move the box 5 mobile on the slide 4.

By these non-limiting means and representing an embodiment with application of a universal and unique compact device for assistance with closing and opening, and for positioning one or more mobile leaves of any kind of sliding sash , the invention has met the necessary and sufficient essential conditions of compactness, simplicity of implementation, performance compliant with standards and increased endurance, for new sliding doors as well as for maintenance or repairs of old sliding doors.

It should be specified that advantageously the nature of the materials, the dimensions and the mass of the fixed and mobile frames of sliding sashes are of little importance because the device of the invention is based on a principle of plates of minimal bulk and the principle of reversible application for any angle of sliding leaves.

A preferred mode of operation of the invention is as follows:

Starting from a closed leaf, the opening of the sliding leaf will correspond to arming or rearming of the device. The opening maneuver will initiate the engagement of the upper pinion 3 on the rack 2 directly generating a vertical displacement of the slider 24 integral with the rod 48 of the cylinder 26 thus compressing the cylinder 26 which gradually accumulates the kinetic energy of the movement of opening until the end of the rack run. The jack 26 acts as a shock absorber. The movement, whatever its speed, has been damped in a firm but progressive manner in proportion to the rise in the compression of the cylinder 26. This end of stroke due to the settings corresponds to the smooth immobilization of the sliding leaf against the fixed frame. The engagement of the upper pinion 3 on the rack 2 is retained. The slider 24 is in the lowest maximum position. The flexible arms 35, 36 of the fork of the slider 26 provided with the end studs 37, 38 under the action of the spring blades 42 are engaged and held in the respective latches 40. The device of the invention is in the rest state and armed. When the rack 2 is placed on an intermediate sliding sash or if the rack 2 does not abut the end of the transom of the frame of this sash, then this sliding sash can freely continue its damped movement until it comes into contact with the sleeper.

Starting from an open leaf, the closing of the sliding leaf will correspond to a triggering of the device. The closing maneuver will initiate the drive of the pinion 3 which was no longer engaged on the rack 32 of the slider 24 actuating in cascade the two other pinions 19, 20, which in turn initiate the drive of the slider 24 in a movement vertical upwards, causing the unlocking and therefore the release of the end studs 37, 38 against the action of the spring blades 42 of the respective latches 40. The unlocking releases the rod 48 of the cylinder 26 which releases the stored kinetic energy, the transmits it to the slider 24 which in turn passes it on via the gear 21 to the rack 2. This relaxation of the device will gradually assist the start of the opening. Cylinder 26 acts as a motor. The motor function will cease as soon as the pinion 3 disengages from the rack 2 and the sash can freely finalize its closing movement at the assisted start until it comes into contact with the frame and, in the case of multiple leaves, until its closing reference point.

Although the invention has been described in connection with particular structures, it is in no way limited thereto and numerous variant embodiments can be made thereto. For example, the hydraulic cylinder 21 can be replaced by a mechanical or pneumatic cylinder or even by a motor. It can be added additional locking means, added or deleted steps in the blocking or unblocking process.

Although the invention has been described in connection with particular structures, it is in no way limited thereto and numerous variations can be made thereto.

The combinations of the different embodiments shown in the drawings or described above do not depart from the scope of the invention.
