Description

"Device for fixing a covering sheet against a wall or the like" The present invention relates to the device used for fixing a covering sheet, for example a drapery, in front of a wall or the like.

More specifically, it relates to devices of this kind which are constituted by a profiled bar intended to be itself fixed, for example by nailing or gluing, on one of the edges of a wall, and which has a groove s' opening on its front face to receive the corresponding edge of a hanging or the like, the groove thus provided in such a bar must have an appropriate inclination, so that the edge of the hanging, preferably wrapped beforehand around a rod stiffening, is stuck in this groove under the effect of the tension exerted on this hanging when it is in place. Thus, when it is a device intended to secure the upper edge of a curtain, the groove provided in the corresponding bar is inclined upwards. Under these conditions, to install a wall hanging in front of a wall, it suffices to engage its upper edge in the inclined groove of such a bar and then to fix its lower edge against the corresponding part of the wall by exerting sufficient tension on this wall hanging. To this end, it is possible to fix the lower edge of the curtain by means of devices such as those described in French patent N ° 70 35461 of October 1, 1970 in the name of the Applicant and in the certificates of addition N ° 71 01278 , N ° 71 21423 and N ° 73 13033 relating to said patent.

However, the profiled bars of the type recalled above have two particularly troublesome drawbacks, namely the fact that they are limited to a specific mode of use and that their fixing by nailing raises significant difficulties.

Regarding the first point, it should be noted that the profiled bars of the type described above cannot not be used to secure the vertical edges of a curtain along the jamb of a door or window frame. Indeed, such bars would have the drawback of remaining visible on their edges, which would be particularly unattractive. This is why, in this case, profiled bars of a different type are used, in this case bars in which the fixing groove opens at the rear or on the corresponding edge of the bar. Thus, when the vertical edge of a curtain is in place in such a groove, the edge of the bar is covered by the curtain itself.

However, this implies for manufacturers to produce two different types of profiled bars. As for resellers, they are obliged to have two separate stocks of profiled bars and users must also obtain two different series of such bars, which is also a drawback for them.

With regard to the second drawback of bars of the type mentioned above, it results from the fact that the driving of nails through them very frequently causes them to burst, even when the thickness of these bars is relatively large. Moreover, it is practically impossible to fix such bars by nailing by means of a pneumatic tool, since the impact of the nails is then such that it inevitably causes them to burst. However, due to the fact that most of the walls are currently made of concrete, without plaster coating or with a coating of very thin thickness, the only way to fix an element against such a wall is to proceed with its nailing by means of nails made of steel, driven in with a pneumatic device. Indeed, fixing by gluing is ineffective due to surface defects and inevitable deformations of the walls. the object of the present invention is to produce a bar profile, of the same kind, which is designed so as to eliminate the two drawbacks mentioned above. To this end, the structure of this bar is such that it can be used for at least two different uses, and that moreover, it can be fixed by nailing using a pneumatic tool.

To this end, the present bar produced so as to be able to be used in a versatile manner, comprises two flat walls, spaced from one another, corresponding to one and the other of its faces, and which are connected by transverse partitions forming as many hollow compartments through which nails can be driven in in the event of fixing by nailing. Furthermore, this bar is reversible in the sense that it can be fixed to a wall by applying against it one or the other of its faces, which makes it possible to orient the groove of this bar either towards the 'front or back, for two different uses.

Due to the particular structure of this bar, it can be perfectly fixed by nailing by means of a pneumatic tool. Indeed, in such a case, this structure plays in a way, the role of a damping box, as will be explained in detail later. the original structure of this bar also has the advantage of allowing reversibility thereof and therefore two different modes of use, avoiding having to have two distinct types of profiled bars to be able to fix a drapery respectively on its upper horizontal edge and on its vertical edges, along the jamb of a door or the doorway of a window. However, in a more improved embodiment of the present bar, it has a second groove provided on its edge opposite the edge comprising the inclined groove for fixing the edge of a curtain. The presence of this second groove allows a third mode of use different from the present bar, which can indeed be thus fixed on the pivoting legs of a series of tensioning device provided for fixing the lower edge of a hanging.

In this case, the first groove of the present bar is used for fixing the corresponding edge of the hanging.

However, other particularities and advantages of the profiled bar according to the invention will appear during the following description, given with reference to the attached drawing for information only, and in which:

Fig. 1 is a perspective view of the present profiled bar; Fig. 2 is a vertical section view illustrating two different modes of use of the present bar respectively for fixing the upper edge and for mounting the lower edge thereof on tensioning devices; Fig. 3 is a sectional view on a different scale, illustrating in more detail the first of these three modes of use;

Fig. 4 is a horizontal sectional view of two bars according to the invention fixed vertically along the vertical edges of two window openings, and which are intended to be used for fixing a curtain in front of a partition situated between them this; Fig. 5 is a horizontal sectional view on a different scale, showing in more detail one of the bars of FIG. 4; Fig. 6 is a partial sectional view illustrating the conditions for driving a nail through the present profiled bar; Fig. 7 is an end elevational view of a simplified embodiment of the profiled bar according to the invention; Fig. 8 is an end elevational view of another more improved embodiment; Fig. 9 is a sectional view of the corresponding bar when used in a form similar to that shown in FIG. 3.

Fig.10 is a horizontal sectional view showing two different modes of use of two bars such as that of Figure 8; Fig.11 ballast a horizontal sectional view showing yet another embodiment of the bars according to the invention; the profiled bar 1 shown in fig.1 is constituted by a kind of hollow box having two parallel walls 2 and 3, spaced from one another and forming one and the other of its faces. These two walls are joined to one another by several transverse partitions 4 delimiting between them interior compartments.

On one of its edges, this bar has a groove 5 which opens on one of the faces thereof, in this case that corresponding to the wall 3. Furthermore, this groove is inclined towards the outside of said bar. Indeed, its median plane XX ′ forms towards the outside, an acute angle relative to the external face of the wall 3.

On its opposite edge 6, the bar 1 has a second groove 7 which opens thereon. the median plane of this groove is parallel to the external faces of the two walls 2 and 3. The particular role of this groove will be explained below.

As can be seen from the figures, the external faces of the two walls 2 and 3 are perfectly flat. Under these conditions, the present bar is reversible, in the sense that it can be fixed to a wall M by applying either one or the other of its walls against it, which modifies the orientation of the groove 5 thereby allowing two different uses of this bar. So Figure 3 and the top of Figure 2 represent the case where this bar is fixed against a wall M by applying against it, its wall 2. Under these conditions, the opening of the groove 5 is then oriented towards the front, so that it can be used to fix in place the upper edge 8 of a curtain T1. In this case, the bar 1 is fixed along the upper edge of the wall M, as shown in Figure 3, that is to say by placing upward, its edge which includes the groove 5. This is so itself tilted up. To fix in place the upper edge 8 of the corresponding curtain T1, it is sufficient to engage it inside the groove 5 of the bar 1, after having wound it around a stiffening rod 9. Due to the 'particular inclination of the groove 5, the upper edge of the curtain T1 is applied against the corresponding ceiling P, which avoids the existence of an unsightly gap. In addition, the bar 1 is completely concealed behind the curtain T1.

Still due to the particular inclination of the groove 5, the upper edge of the drapery is perfectly fixed in place and does not risk inadvertently emerging outside this groove. In fact, it is stuck in it because of the tension exerted on the curtain T1 when the latter is fixed in place. For this purpose, the lower edge of the latter can itself be fixed against the lower part of the wall M1 by means of fastening devices under tension, such as those recalled previously, in this case devices as described in the patent. French 70 35461 and its various certificates of addition.

Thus, in the example illustrated in FIG. 2, the lower edge of the curtain T1 is fixed in place by means of a certain number of tensioning devices, such as those described in the addition certificate deposited by the Applicant on June 21, 1979 under No. 79 15900. One of these devices is shown in the lower part of Figure 2 under the general reference 10. As described in the certifi addition cat mentioned above, this device therefore comprises a pivoting tab 11 which is folded down when the corresponding drapery is fixed in place and tensioned. This tab is provided with a tongue 12 on which is attached a profiled rod used for fixing the lower edge of a hanging.

However, by the very fact of the existence of the groove 7 on one of the edges of the bar 1 according to the invention, it can be used in place of such a profiled rod. In fact, as shown in the lower part of FIG. 2, the present bar can be attached to the pivoting tab 11 of the lower tensioning devices 10 by engaging the tongue 12 of the pivoting tab of the latter inside. groove 7 of this bar. In this case, the first groove 5 thereof is therefore placed downwards. However, as in the previous case, this groove is open .forwards, it can therefore receive the lower edge 13 of the curtain T1, the latter being wound around a stiffening rod 9, before be engaged inside the throat 5.

Thus, the structure of the profiled bar according to the invention makes it possible to avoid having to use a particular type of profile to fix the lower edge of the hanging on the tensioning devices provided at the bottom. The same type of bars can therefore be used both to immobilize the lower edge of a curtain against a wall and to fix its lower edge on tensioning devices.

However, Figures 4 and 5 illustrate yet another possibility of using the profiled bar according to the invention. Indeed, in the case thus illustrated, this same bar is used to fix in place the vertical edges 14 of a curtain T2, along the embrasures of two windows F1 and F2. The bars 1 used for this purpose, are then turned on themselves, so that it is their wall 3 which is applied. quée against the wall M2 and no longer their wall 2. Under these conditions, the groove 5 of these two bars is oriented in the opposite direction, in this case each of these grooves is oriented towards the rear. However, one can engage the corresponding vertical edge 14 of the curtain T2. in such a groove, after having wound it around a stiffening rod 9. As shown in more detail in FIG. 5, the adjoining part of the curtain is thus in a way wound around the corresponding edge of the bar 1. Under these conditions, it is completely concealed by the hanging. The profiled bar according to the invention avoids denc to have recourse to another "particular type of profiled bar to fix in place the vertical edges of a hanging along a window or a door. However, it is advisable to note that to switch from the mode of use represented in FIG. 3 to that illustrated in FIGS. and 5, it suffices to turn the present bar over on itself so as to fix it against the wall by applying its wall which i was previously This is made possible by the particular structure of this bar which allows its reversibility.

Furthermore, this structure in the form of a hollow box has the advantage of allowing the fixing of this bar by nailing by means of a pneumatic device. Indeed, fixing nails 15 can be driven through the compartments of this bar existing between two transverse partitions 4, without any risk of bursting of the crossed walls, that is to say the walls 2 and 3. The removal of this risk comes from a number of factors. Among these, it should first be noted the reduction in thickness of the two walls 2 and 3 compared to the thickness of a profiled bar which would be full, as was the case for the bars used until now for the same use. Indeed, due to the realization of this bar in the form of a hollow box, the thickness of the walls 2 and 3 can be relatively small, so that these are very easily crossed by a nail 15 driven by a pneumatic device.

On the other hand, it should be noted that the structure of this bar allows it to play the role of a damping box. Moreover, when driving a nail 15, the head 15a thereof presses against the wall located on the outside, for example the wall 3 and this on a part of it which is located between two interior partitions 4. Consequently, this part of the wall 3 is caused to bend slightly as shown in FIG. 6, between the two rigid support points of this wall, which correspond to the two adjacent transverse partitions 4. This phenomenon therefore avoids the risks of the wall located on the external side bursting, in this case the wall 3 in the example considered in FIG. 6.

As for the other wall, that is to say the wall placed in contact with the wall, it is applied flat against the latter but not subject to the impact of the tip head from which it is spaced. This particular feature also has the advantage of avoiding any risk of the wall bursting.

Consequently, the present bar can therefore be fixed very easily on a concrete wall having no coating and this, by nailing by means of driven nails using a pneumatic device. To facilitate this operation, the external faces of the bar 1 may advantageously include means of marking indicating the position of the hollow compartments through which fixing nails can be driven. These locating means may possibly consist of slight grooves 16 extending opposite the compartments located between two successive transverse partitions 4. In an improved variant, the present bar is provided with small pieces of adhesive material covered, before use, by a protective sheet. These pieces of adhesive material temporarily fix the bar in place. against a wall, so that nailing can then be done very easily. In addition it is possible to check and correct, if necessary, the exact position of this bar before nailing. However, the use of this bar is not limited to fixing by nailing. Indeed, it can also be fixed by stapling or gluing. In the latter case, the fixing is very effective, both on one face and on the other, since the bonding is carried out on a large surface, in this case the entire flat surface of the corresponding face.

In addition to the advantages already explained, this bar has the advantage that its structure in the form of a compartmentalized box gives it very good rigidity with little material, which allows an appreciable economy. Furthermore, the great rigidity of this bar allows it to withstand, without deformation, the forces due to the weight of a drapery and to the traction exerted by it due to its tension.

Of course, the bar according to the invention is not limited to the single embodiment described above.

Thus, Figure 7 shows another simplified embodiment in which the corresponding bar 1a has a single groove, in this case the inclined groove 5 provided along one of its edges. Indeed, the second groove 7 existing in the bar described above is deleted. Under these conditions, the bar 1a is not capable of being mounted on tensioning devices such as the device 10 shown in the lower part of FIG. 2. On the other hand, this bar 1a has the same advantages the bar 1, with regard to the other modes of use thereof, that is to say the two modes of use shown respectively in FIGS. 3 and 5. In fact, bar 1a is reversible, as is the bar 1, so that its inclined groove 5 can be oriented either towards the front or towards the rear. This allows to use it indifferently how to fix the upper edge of a drapery or the vertical edges of it along a window or door.

FIGS. 8 to 11 show another embodiment of the profiled bar according to the invention, which is even more improved than that of FIGS. 1 to 6.

In this embodiment, the two walls 2b and 3b of the corresponding bar 1b are no longer parallel to each other as was the case in the previous embodiments. In fact, these two walls converge towards one another in a direction opposite to the edge of the bar on which the inclined groove 5 open on the side of the wall 3b is provided. Under these conditions, the thickness of this bar decreases on the side opposite this groove. The angle between the external face of the wall 3b of the bar and the vertical curtain T1 can vary between 8 and 12 degrees approximately; it is preferably 10 degrees.

This has the advantage that, in the case of fixing by nailing, the heads of the fixing points 15 are thus clearly set back relative to the curtain T1 which extends parallel to the wall M1. Moreover, this is clearly shown in Figure 9 which illustrates the use of such a bar for fixing the upper edge of a curtain T1 in front of a wall. This advantage also exists when the bar 1b is used in the form shown in FIG. 4, that is to say in a vertical position to fix the edge of a curtain T2 along the opening of a window. Furthermore, this is illustrated by the lower part of FIG. 10 which represents a bar 1b fixed in an inverted position with respect to that provided in FIG. 9.

Indeed, this bar is fixed in place by applying its wall 3b against the corresponding wall. But again, the particular shape of the bar 1b, which determines a reduction in thickness in the direction opposite to the groove 5, has for advantage that the corresponding curtain T2 is clearly spaced from the head of the fixing points 15.

However, the bar 1b has another improvement which allows an additional mode of use of this bar, in this case its use for fixing the vertical edge of a drapery along a window opening or the like comprising a small jamb C. Indeed, in such a case, it is not possible to use one of the bars 1, 1a or 1b in an inverted position, because there would be no possibility of passage for the introduction from the edge of the hanging previously wrapped around a stiffening rod.

To resolve this particular problem, the bar 1b ^shown in FIG. 8 has the additional characteristic that the groove 7b, provided on its edge opposite the inclined groove 5, is formed by two walls 17 and 18 of unequal lengths. Thus, there is an offset e between the two ends of these walls, which can be from 2 to 4 mm approximately, and preferably 3 mm. Under these conditions, the groove 7b can be used to fix therein the vertical edge of a hanging along a jamb C by then placing towards the outside, the wall 17 of this groove which has a shorter length. . Indeed, there is thus a free passage allowing the introduction of the edge of the drapery and the stiffening rod 9, around which this edge has been previously wound. This additional possibility of using the bar 1b is moreover illustrated in the upper part of FIG. 10. However, the difference in length of the two walls of the groove 7b does not in any way hamper the first mode of use of this groove such as described above in the case of the groove 7 of the bar 1, with a view to mounting the present bar on the pivoting tab 12 of a tensioning device 10. Consequently, this bar therefore retains the same possibilities of use as previously. It should be noted that the profiled bar according to the invention can also be used to ensure the connection of two strips of tissue L1 and L2 one after the other. Usually, such a connection is made by sewing. However, this leads to wasted time and involves delicate work, the result of which is not always perfect.

However, as shown in FIG. 11, it is possible to make such a connection by fixing head to tail two bars 1b joined against each other by their edge comprising the inclined groove 5.

Moreover, in an advantageous embodiment of the device according to the invention, there is provided a one-piece element manufactured by extrusion and constituted in a way, by two bars 1b arranged head to tail and integral with one another according to a contact line 19.

In this regard, it should be observed that the external faces of two walls 2b of these two bars are then arranged in the same plane. Thus, they can be fixed against an M3 wall. The use of such a double profiled bar has the advantage of requiring a single laying operation. In addition, a perfect linear regularity is thus obtained of the connection line between the two strips of tissue L1 and L2. In addition, a sharp joint is thus created between the two strips of fabric, which therefore ensures a perfect result.

Of course, the profiled bar according to the invention can be manufactured and marketed in the form of a one-piece element such as that shown in FIG. 11 and which therefore comprises two bars 1b arranged head to tail. Depending on the case, this element can be kept in this form for the connection of two strips of tissue or else be broken by the medium for the various other modes of use described above. It should be noted that the tensioning device 10 can be placed both vertically and horizontally and not only along the lower edge of the hanging as shown in the drawings, especially for the surrounding of the openings since it has the advantage of touching the. wall by completely covering the edge of the device with fabric.

Optionally, the present profiled bar can also be used to fix in place one of the edges of a covering element for the floor or the ceiling, for example a plastic covering sheet or mat.
