Abstract

The roller assembly consists of rollers (9) in a housing (10) which can be adjusted for height by moving it along inside the lower frame member (2). The longitudinal movement of the roller housing is accomplished via a screw (24) which passes through a cantilever bracket (25) on the vertical edge of the frame to engage with a nut (27) and a transmission rod (28) connected to the housing. The cantilever bracket is preferably a metal or plastics strip with its lower end turned inside the lower frame member, while the vertical adjustment of the roller housing is achieved by interacting sloping surfaces (15,16) on fixed and moving components. Alternatively, these can be a transverse peg and a sloping slot.

Description

The invention relates to a rolling device for equipping the horizontal lower cross member with an opening sliding door, window or the like and comprising, of a part, rolling means in the form of at least one roller rotatably mounted in a housing and, on the other hand, means for adjusting the height of said rolling means in the form of means able to transform a longitudinal impulse and horizontal exerted on said casing by control means comprising an adjusting screw in a component displacement vertical of this housing.

The present invention will find its application in the field of the building hardware and, more particularly, in that of fittings intended to equip sashes sliding.

We already know a good number of rolling devices meeting the description above.

Thus, such a rolling device, more particularly applicable to sliding doors, windows or analogues, comes in the form of a set that we just lodge in a groove and / or a notch formed at the level of the horizontal lower cross member of said opening. This set includes rolling means in the form of at least one roller coming to cooperate with a rail equipping the lower cross member of the sleeping frame for this door, window or the like. In sight to adjust the position of the opening relative to said frame these rolling means are frequently adjustable in height. More particularly, said roller is mounted in rotation in an otherwise mobile casing relative to a support which can be in the form of a housing. The adjustment means consist of means capable of transform a longitudinal and horizontal impulse exerted by appropriate control means on said housing in one vertical component displacement of the latter relative to its support.

Thus, by way of example, said casing can have at the level from its side walls, an oblique light crossed by a axis arranged transversely inside a housing welcoming this housing. Therefore, by ensuring, effectively, the displacement of the latter inside said housing, in a longitudinal direction, it results, under the influence of the cooperation of the lights and the axis, a displacement with a vertical component of this housing. One can, of course, consider equipping, also, the side walls of the housing of said oblique lights in which are able to stand move the ends of an axis crossing the housing while being in solidarity with the latter.

Similarly the housing or the support can be equipped, in its internal part, of an inclined ramp on which comes to take supports a counter-ramp associated with the casing so that, in moving the latter longitudinally inside said housing, it follows a vertical displacement of the means of rolling.

As for the control means intended to act on this casing to carry out the desired adjustment, they usually present themselves in the form of an adjustment screw engaged in a tapped hole formed at one of the transverse ends of the housing, this adjusting screw bearing, at its end free, on the transverse wall of the casing. The orientation of machined oblique lights, either in the side walls of the casing, either in those of the case or, as the case may be, the orientation of the ramp and the counter-ramp associated with these latter, is thus determined that under the influence of the weight of opening said housing is systematically pushed back against said adjusting screw.

Consequently, by acting on the latter, the user can perfectly adjust the position of the sash relative to the sleeping frame.

However, it will be observed that this user only has the sole clearance between the rebates of the lower crosspieces, respectively, of the sliding sash and the frame for access the adjustment screw and, finally, order it in rotation if he does not wish, of course, to remove the sash. That explains why in many cases and in the absence of a specific tool, this removal of the opening is ultimately unavoidable to ensure the maneuver. Also, it It goes without saying that such a design of the adjustment means is not hardly practical.

It is also known from document GB-1.580.618, a rolling device intended to equip the cross member bottom of a sliding door leaf comprising, of a part, rolling means in the form of a roller mounted in rotation in a housing. This device also comprises means for adjusting the height of said rolling means in the form of means capable of transforming an impulse longitudinal and horizontal, exerted on said casing by control means comprising an adjusting screw, in one vertical component displacement of this casing. In fact, this adjusting screw passes through a mounting bracket attached to the vertical edge of the sliding leaf in order to cooperate with a nut fitted to a transmission rod extending under the lower cross member of the sliding leaf and connected to said audit casing.

It is also known, from document US-4 674 232, a device bearing defined by a housing having a wall upper, side walls and end walls, one of these being crossed by an adjusting screw suitable for adjusting the height of the rolling means in the form of a pebble that comes to accommodate this housing. In fact, this adjustment screw is accessible from one of the walls end corresponding to this housing and which is, moreover, extended upwards like a fixing console coming from integrate into the front or, as the case may be, rear edge of sliding door. This fixing console has a orifice capable of being crossed by a fixing screw allowing, alone, to make the rolling device integral this sliding door.

We understand, of course, that in such a configuration we is in no way confronted with the problem set out above in the measure where the rolling device is, here, intended to be placed directly under the front or rear post of the sliding sash, which of course makes it accessible to level of the front or rear edge of the latter the adjusting screw in height of the rolling means. However, it should be observed that, in contrast, such rolling devices are only very rarely placed directly under the front uprights and rear of a sliding window but are installed, in particular to allow a perfect resumption of the load of this opening sliding under it, in an inaccessible way.

Ultimately, it is to this very particular problem that the present invention wants to be able to respond, everything particularly by making these means of adjusting a rolling device perfectly accessible, even when this is not directly below the amount before or back of the sliding sash.

• les moyens à même de transformer une impulsion longitudinale et horizontale en un mouvement vertical comportent un premier élément solidaire du carter, coopérant avec un deuxième élément solidaire de l'ouvrant, pour transformer l'impulsion horizontale exercée sur le carter en un mouvement à composante verticale de ce carter ;
• la console de fixation se présente sous la forme d'une lame et comporte, à son extrémité inférieure, un orifice pour le passage de la vis de réglage.

To this end, the invention relates to a rolling device intended to equip the lower cross member with a sliding door, window or similar opening element, comprising, on the one hand, rolling means in the form of at least one roller mounted in rotation in a casing and, on the other hand, means for adjusting the height of said rolling means in the form of means capable of transforming a longitudinal and horizontal impulse, exerted on said casing by control means, into a displacement at vertical component of this casing, said control means comprising an adjustment screw passing through a fixing console, attached to the front or rear vertical edge of the sliding leaf, in order to cooperate with a nut fitted to a extending transmission rod under the lower cross member of the sliding leaf and connected to said casing, characterized in that:

• the means capable of transforming a longitudinal and horizontal impulse into a vertical movement comprise a first element secured to the casing, cooperating with a second element secured to the opening, to transform the horizontal impulse exerted on the casing into a movement with vertical component of this housing;
• the fixing console is in the form of a blade and has, at its lower end, a hole for the passage of the adjusting screw.

According to an advantageous embodiment, the fixing console is defined by a headrest corresponding to a locking and fitting the front and / or rear vertical edge of the sliding leaf, said headrest comprising, at its lower end an orifice for the passage of said screw fixing in order to allow the latter to cooperate with said transmission rod implanted in a groove and / or a cut made in the lower edge of the lower cross member of this sliding leaf.

Since it is customary to equip a sliding door that of a single adjustable bearing device, this is preferentially located on the side of the upright before this sliding door so that it will suffice for the user or fitter to open his door or window to be able to access the adjusting screw, in the lower part of said upright before opening it to change the position of the latter by compared to its sleeping frame. Note that this editor or this user has sufficient space at this level to proceed with the maneuver without having to contort or even to use a specific tool.

As will appear further in the description, both the fixing console that the transmission rod can take position in the peripheral grooves which equip, usually, such a sliding opening for the implantation of a suitable opening and closing mechanism, such as cremone bolt, lock bolt or other.

Les figures 3 et 4 correspondent à des vues similaires, respectivement, 1 et 2 et illustrent un autre mode de réalisation de ce dispositif de roulement conforme à l'invention.

The invention is explained in more detail in the following description relating to embodiments given by way of examples and illustrated in the accompanying drawings.

Figure 1 is a schematic view in longitudinal section of a rolling device according to the invention located at the lower edge of a door leaf, window or the like slidably mounted on a frame;

Figure 2 is a schematic view in cross section of this rolling device, also being shown, the lower cross member of the sliding leaf, as well as the upper cross member of the frame receiving the rail on which rests said rolling device.

Figures 3 and 4 correspond to similar views, respectively, 1 and 2 and illustrate another embodiment of this rolling device according to the invention.

As shown in Figures 1 to 4 of the accompanying drawings, the present invention relates to a device for bearing 1 intended to equip the lower crossmember horizontal 2 of a sliding leaf 3 of door, window or similar, knowing that this rolling device 1 is provided to cooperate with a rail 4 fitted to the rebate of the lower cross member 5 of the frame 6.

Thus, this rolling device 1 comprises means for bearing 8 in the form of at least one roller 9 coming to rest on said rail 4. In reality, this roller 9 is rotatably mounted in a casing 10 knowing that the rolling device 1 comprises, in addition, height adjustment means 11 of said means for bearing 8. In this regard, these adjustment means 11 are present in the form of means capable of transforming a longitudinal and horizontal momentum exerted by means control 12 suitable on said housing 10 in one movement with vertical component of the latter.

In fact, there are different embodiments of such means capable of transforming a rectilinear displacement of the housing 10 in a displacement with vertical component, such as this is apparent from Figures 1 and 2, on the one hand, and 3 and 4 on the other go.

Thus, in the context of the solution proposed in Figures 1 and 2, it is located at the bottom of the groove and / or notching 13 formed in the lower edge 14 of the lower cross member 2 receiving the rolling device 1, a support ramp inclined 15 with which is intended to cooperate a counter ramp 16 associated with the casing 10 so that by moving the latter, substantially parallel to the lower cross member of the sliding leaf 3, the counter-ramp 16 moves along the inclined support ramp 15 which effectively results in the displacement of said casing 10 along a component trajectory vertical.

As part of the solution proposed in Figures 1 and 2, it is noted that the rolling device 1 comprises a support 17 attached, as the case may be, directly or by means a wedge 18 (see FIGS. 3 and 4) at the bottom 19 of the groove and / or notching 13. On this support 17 is fitted, in part, the casing 10 allowing, respectively, the support ramp inclined 15 and against the ramp 16, to cooperate with one the other.

As shown in Figure 3, said means able to transform a longitudinal and horizontal pulse on the housing 10 in a vertical component displacement can still come in the form of an inclined light 20 formed at the support 17 and crossed by an axis 21 which, it is secured at its ends to the housing 10. It is obvious, therefore, that by moving the latter and under the influence of the cooperation of axis 21 with said light inclined 20, this results in a component displacement vertical of this housing 10.

In addition, we can also consider saving, at the level side walls 22, 23, casing 10, such lights inclined in addition crossed by an axis made integral, in this case, support 17. Indeed, this inversion kinematics hardly changes the desired result.

The originality of the present invention lies in the fact that the control means 12 capable of exerting an impulse longitudinal and horizontal on the housing 10 comprise at minus an adjustment screw 24 passing through a fixing console 25 attached to the vertical edge before 26 and / or rear of the sliding leaf 3 in order to cooperate with a nut 27 fitted to a transmission rod 28 extending under the lower cross member 2 of the sliding leaf 3 and connected to the housing 10 of the rolling device 1. Thus, under the influence the rotation of said adjusting screw 24 results therefrom, specifically, the movement control of said casing 10.

The above construction results in an adjustment particularly easy sliding door 3 compared to its sleeping frame 6 insofar as access to the adjustment of the rolling device 1 is particularly easy and in all cases avoids the use of tools specific.

It should be observed with regard to the console fixing 25, that this can be presented, simply, under shape of a metal or plastic blade with holes used, for some, for the passage of fixing screws of this blade on said front vertical edge 26 or rear of the sliding leaf 3, and, for that located at the end lower of this blade when the adjusting screw 24 passes. made, such a blade is provided, at its lower end, a wing 29 folded in a square extending, partially, to lower edge level 14 of lower crossmember 2 corresponding to this sliding leaf 3. This wing 29 contributes to the correct positioning of this fixing console 25 on the latter.

However, it can also be constituted, substantially, by a headrest corresponding to a fitting locking mechanism of the lever type or lever-lock and installed in a notch or a groove 30 provided for this purpose at the level of this vertical edge before 26 and / or rear of this sliding door 3. In such a case, this headrest has, at its lower end, an orifice 31 for the passage of said adjusting screw 24. Note that if at the rear from this headrest moves an operating rod corresponding to the locking fitting, such a rod is itself provided with a light to the right of the orifice 31 corresponding to the headrest to allow this passage of the screw 24 and the displacement of the rod of the lever.

The adjusting screw 24, like the transmission rod 28 preferably extends inside the groove 13 formed at the level of the lower edge 14, in which is, by elsewhere, engaged the rolling device 1. In the absence of such a groove 13, this adjusting screw 24 and the rod transmission 28 can be housed in a notch appropriate present at the level of this lower song 14 of sliding door 3.

In this regard, it will be observed that it is usual to find, in periphery of these sliding doors or windows, such a groove or notching specifically intended for accommodate any kind of locking mechanism, groove or tapping that we can, precisely, take advantage of for housing all the components of the bearing according to the invention. In fact, we see that this bearing device requires little operation additional machining for its installation on an opening sliding, this compared to adjustable rolling devices known in the state of the art.

Regarding the nut 27 fitted to the rod transmission 28 for receiving the adjusting screw 24, it is cleverly in the form of a folded wing 32 square at the free end 33 of this rod transmission 28, this wing 32 being perforated with an orifice tapped 34 for receiving said adjusting screw 24.

To avoid that under the effect of the feedback according to the case, of the inclined support ramp 15 on the counter-ramp 16 or still tilted light 20 on the axis 21 the weight of the opening 3 is transformed into a thrust of the casing 10, by via the transmission rod 28 on the console 25, the orientation of these ramps and counter-ramps 15, 16 or even inclined light 20 is determined to so that when it rests on the rail 4, the casing 10 of the bearing 1 pulls on the transmission rod and, therefore, on the adjusting screw 24.

In return, to avoid during the shoeing of the opening sliding 3 relative to the sleeping frame 6, that the casing 10 of the rolling device 1 does not move freely in one either direction, the control means 12 are supplemented by means of immobilization in translation of the adjusting screw 24 relative to the fixing console 25. From such means of immobilization in translation 35 can be present in different embodiments, including in the form of a circlip mounted on this adjusting screw 24, at the rear of the fixing console 25. However according to one mode preferential execution illustrated in the attached drawings, these means of immobilization in translation 35 are constituted by a helical spring mounted on said adjusting screw 24 while being interposed between the fixing console 25 and the nut 27 of the transmission rod 28. Consequently, for the fittings, the manufacturer has a complete set and relatively rigid. In addition, when installing the opening sliding 3, the casing 10 retains its position in the measurement where its transmission rod 28 cannot move in direction of the fixing console 25 without opposing said audit coil spring 36.

According to another characteristic of the present invention, this rolling device 1 comprises means 37 for indexing the position of the casing 10 relative to its support 17 with a view to facilitate installation for the fitter. It is indeed necessary to observe only if the adjustment means were, until then permanently on the rolling device 1, they are, here, dependent on the positioning of said support 17 relative to the console fixing 25. Also, if said support 10 is not attached to the lower cross member 2 of the sliding leaf 3 at one dimension determined from said fixing console 25, this may result a reduction in the possible adjustment range. Finally, such consequences are avoided as soon as the positioning of this support 17 is indexed relative to the housing 10 itself, connected by means of the transmission rod 28, to the adjusting screw 24 and, therefore, to said fixing console 25.

As shown in the illustrated embodiment in FIGS. 1 and 2, these indexing means 37 are present in the form of an associated breakable nipple 38, by example, at the inclined support ramp 15 and engaged with a light with sharp edges 39 present at the level of the counter ramp 16. Thus, in the event of displacement of the casing 10 relative to to the support 17 under the action of the adjusting screw 24, this stud 38 is sectioned. Preferably, this comprises a form in a T so that its horizontal wing portions 40, 41 can be positioned under the flanges 42, 43 of the light 39 corresponding to the counter-ramp 16. Consequently, such an indexing pin 38 also contributes to maintaining of the casing 10 on the support 17 before mounting the device bearing 1 under the sliding leaf 3. Thus, the fitter can it have a pre-assembled assembly whose installation is made particularly easy.

As part of the solution shown in Figures 3 and 4, these indexing means 37 preferably take the form a choke, almost at the end of the light inclined 20 formed at the level of the support 17 allowing to immobilize momentarily in translation, the axis 21 in this tilted light 20.

Finally, we see from the above description, that the present invention responds, particularly advantageous to the problems posed by the state of the art bearing.
