FIELD OF THE INVENTION The present invention relates to means for securing covering sheets such as fabric hangings or tapestry to any surface such as a wall, partition or ceiling.
DESCRIPTION OF THE PRIOR ART As a rule fabric sheets are fixed by inserting nails or staples through the edges of the covering sheet, these nails or staples being driven through the material of the wall or ceiling surface to be covered. However, it is a primary requirement that the sheet be properly tensioned. To this end, the upholsterer must firstly fix one of the edges of the sheet in place, and then anchor the opposite edge while exerting a tractive force on the covering sheet. This last step is rather difficult to perform. This is the reason why tapestry coverings can only be applied by skilled professionnals or at least by persons endowed with considerable manual skill. In many cases the tension of the fabric or other covering material is not satisfactory and folds or pleats, or other unaesthetic defects, appear.
This method of securing the fabric is particularly time-consuming inasmuch as the heads of the nails or staples, or the nails or staples themselves, must be concealed by resorting to some co'ntrivance or adding a complementary covering element such as a strip, molding or decorative tape.
It has already been proposed to secure such hangings and tapestries by using a device consisting of the combination of a fixed rod, adapted to be secured to the surface to be covered, with a rigid strip pivotally mounted on the rod and adapted to support the covering sheet. Under these conditions, the sheet can be tensioned by simply folding back the movable strip against the corresponding wall.
However, the devices proposed heretofore are mostly very rudimentary and unsatisfactory. Thus, to retain or lock the movable strip in its end position and properly tensioning the sheet, adequate means must be provided, such as an insert strip secured to the surface to be covered. The provision of the insert strip constitutes an additional operation while attaching the covering sheet to the movable strip also requires the use of special complementary fastening members.
SUMMARY OF THE INVENTION It is therefore an object of this invention to provide an improved device of the same character as the one mentioned hereinabove but designed to permit the easy fixing of a covering sheet against any surface while properly tensioning said sheet. To this end, the fixing device according to this invention comprises a fixed bar and a movable strip, said bar and strip comprising complementary interfitting means adapted to lock the strip in its folded-back position either against said bar, or directly against the surface to be covered, the movable strip further comprising fastening means for securing the covering sheet thereto before the strip is moved to its folded-back position.
According to another feature of this invention the fixed bar and/or the movable strip comprise abutmentforming members adapted to stop said strip in its angu lar position away from said fixed bar.
Thus, the movable strip can be held in a waiting position facilitating the fastening of the corresponding edge of the sheet thereto. Upon completion of this fastening operation it is only necessary to fold the strip back against the fixed rod for securing the corresponding edge of the covering sheet and tensioning the sheet whose opposite edge may be secured in a similar fashion.

Specific Description The device illustrated-in FIGS. 1 and 2 comprises a main bar 1 on which a strip 2 is pivotally mounted along one longitudinal edge. This bar 1 is adapted to be secured, for example by means of nails 3, to the wall P, or any other surface to be lined with a hanging or other covering sheet. More particularly, the fixing of this sheet or hanging requires four fixing devices according to this invention, to be disposed along the two horizontal edges and the two vertical edges of the hanging.
FIG. 1 illustrates two opposite devices according to this invention, disposed along the two horizontal, upper and lower, edges of the same hanging.
The movable strip 2 has one edge pivotally connected by means of a hinge 4 to the fixed bar 1. Thus, the movable strip 2 can be tilted outwardly to a waiting position in order to position its free edge 5 away from the fixed bar 1 (see FIG. 1). However, in the operative position this strip 2 is folded back against the bar 1, as illustrated in FIG. 2.
In the vicinity of its free edge 5 the movable strip 2 is provided with fastening means adapted to secure the corresponding edge of the covering sheet to said strip before moving the latter to its sheet-stretching position against, or in coplanar relationship to, fixed bar 1. In the device illustrated in FIGS. 1 and 2, said fastening means consist of a row of small needles 8 provided on the movable strip 2 in the vicinity of its free edge 5. These needles extend towards the bar 1 and are disposed at spaced intervals throughout the length of strip 2. Along this row of needles the thickness of strip 2 is reduced in order to leave a certain gap between the strip 2 and bar 1 when the former is folded back against the latter (see FIG. 2).
Assembling means are provided for locking the strip 2 in its operative position against the fixed bar 1. These means may consist of a shaped rib 10 carried by the inner face 7 of strip 2 and adapted to fit snuggly in a matching groove 11 formed in the outer face of fixed bar 1. This rib 10 is provided with a retaining bead and the groove 11 is shaped accordingly, as shown.
The device further comprises an ornamental or finishing molding or strip 14 adapted to cover the free end 5 of strip 2. This molding 14 is pivoted to bar 1 by means of a hinge 15 and formed with an integral retaining edge 17 adapted to engage a corresponding groove '18 formed in the outer face of strip 2.
Along its edge opposite said finishing molding 14 the bar 1 carries a row of needles 19 adapted to permit the fixing of a lining sheet 20 behind the hanging 21 to be tensioned between the devices of this invention.
As already mentioned in the foregoing, the hanging 21 is laid against a surface by fixing beforehand a device according to this invention along each edge of said surface. However, the two devices provided along two opposite edges must be directed in opposition so that the free edges 5 of their movable strips 2 lie outwards in relation to said surface when the strips are folded back in their operative positions.
To fix a hanging 21 the first step consists in attaching its upper edge to the needles 8 carried by the movable strip 2 of the upper fixing device, the corresponding marginal portion of the hanging being caused to cover the free edge 5 of strip 2.
Fixing the covering sheet on its effected most easily, as it is done while strip 2 is in its waiting position. away from fixed bar 1. Access to nails 8 or other fastening means provided for this purpose is therefore easy. The fastening operation is then completed by simply pressing the edge of sheet 21 on to the fastening means. Meanwhile, strip 2 is maintained still in the corresponding position because of the abutment means provided for this purpose. The existence of such abutment means is therefore essential to make the operation easy.
Then a similar fixing operation is carried out with the lower edge of the hanging 21 engaging the needles and the free edge of the lower movable strip 2 of the lower fixing device.
After this preliminary operation, the strip 2 of the upper device is folded back against the bar 1 to the operative position shown in FIG. 2, in which said strip is substantially parallel to the surface P to be covered. The retaining ribs 10 and 12 provided on said strip engage the corresponding grooves of the bar, whereafter the finishing molding 14 is folded down to provide an additional locking means for retaining the movable strip 2 in its end position (see FIG. 2).
Then the same sequence of steps are accomplished with the lower fixing device. However, in the specific example illustrated in FIGS. 1 and 2, this lastmentioned operation may be performed in two steps only due to the provision of an additional locking rib 12 carried by the movable strip 2 and adapted to engage the groove 13 of fixed bar 1. In fact, the arrangement is such that this rib 12 will engage the registering groove 13 before the movable strip 2 is folded back completely against the bar 1. Then, the strip 2 is held in this position by its rib l0 and also by its finishing moulding 14.
Under these conditions the hanging 21, consisting for example of a plurality of widths of fabric or similar material, sewn edge to edge, is perfectly taut along the surface to be covered.
Of course, a similar sheet-tensioning operation is performed by means of the fixing devices disposed along the vertical edges of the same hanging.
As will be seen, the device this invention permits of the covering a wall or other surface very easily and rapidly. Due to the great facility of use of this device, it can be installed by any person desirous to cover the walls of a room in a private house with hangings or other sheet material.
Moreover, this device affords a high degree of sound and heat insulation. In fact, due to the particular arrangement contemplated, the hanging 21 is disposed at a certain spacing from the lining 20 also somewhat spaced from the wall proper P. Under these conditions, two air gaps are formed behind the lining 20 and in the space between this lining and the hanging 21, respectively.
Besides, this device permits of using any desired sheet material for the hanging or tapestry, since it is separate from the lining proper.
This device is also advantageous in that it is completed by means designed for fixing in position the various corners of a hanging or tapestry. Two such means are illustrated diagrammatically in FIGS. 3 and 4 and consist each of a plate 22 formed with a thicker portion 23 to which a triangular element 24 is hingedly mounted. The corresponding hinge 25 extends along a diagonal or oblique line of plate 22.
In the inoperative position the hingedly mounted triangular element 24 is turned down as illustrated in FIG. 3. Now the inner face of this element carries two rows of needles 26 extending along the two free edges thereof.
As in the case of the needles 8 carried by the movable strip 2 of the fixing device shown in FIGS. 1 to 3, these needles 26 are adapted to receive the corresponding edges of the hanging or tapestry. Thus, it is possible to fix one corner of hanging 21 to the triangular element 24 hinged to the corresponding fixing member 22. In fact, these fixing members 22 are adapted to be fixed in position beforehand at each comer of the surface P to be covered with the hanging, by using nails or other suitable members.
The corresponding corner of each hanging 21 is then tensioned by simply folding the hinged plate element 24 against the plate 22 of the corresponding device, i.e. to the position shown in FIG. 4. Then the plate element 24 is locked or safely retained in the operative position shown in this Figure by suitable means (not shown) which may be similar to those contemplated for holding the movable strip 2 pivoted to the fixed bar 1.
The component elements of the fixing device of this invention may be manufactured from any suitable material. They can be made in the form of separate elements interconnected by suitable hinge means. However, it is also possible to mold or extrude them from suitable plastic material, the elements being in this case interconnected by thin, flexible lugs or strips acting as the hinge means.
These bars and strips may be produced on a commercial scale in the form of more or less long sections. However, two or more elements may be disposed in mutual alignment for covering one of the edges of a wall throughout its length. Moreover, these elements may easily be cut to the desired and exact length contemplated.
FIG. 5 illustrates an embodiment of this invention, wherein the movable strip 20 of the fixing device is not attached permanently to the fixed rod la. In fact, this strip 20 is pivoted to the bar 1a via a heel 27 carried by the strip and engaging a groove 28 of bar la.
This bar carries on the other hand a projecting ledge 29 (abutment means) engageable by the movable strip 2a and adapted to retain this strip in its waiting or outermost position in which the hanging 210 can easily be secured thereto. As in the preceding examples, the hanging 21a is attached to the strip 2a by a row of me dles 8 carried by the inner face of the free edge of movable strip 2a.
This strip is also provided, as shown in FIG. 5, with a dependingand projecting lip 30 adapted to be retained by a ledge 30a formed on a projecting rib carried by the bar la, when the strip is folded back to its tensioning position as shown in the figure. To interlock the two elements In and 2a it is only necessary to lift slightly the strip 2a and then allow it to drop so that the lip 30 eventually lies in the groove formed behind the ledge 30a.
In the various embodiments described hereinabove the movable strip is mounted to lie against the front face of the fixed bar in the fold-back position of the stri I-lbwever, in the modified embodiment illustrated in FIGS. 6 and 7 of the drawing the arrangement differs in that the movable strip is substantially coplanar with the fixed bar in the operative position of the device.
As in the embodiment shown in FIG. 5, the corresponding movable strip 2b is pivoted to the fixed bar lb without providing any spindle or hinge shaft therebetween. In fact, these two elements are hingedly interconnected by means of cooperating hook-sectioned projections 32, 33 carried by the strip 2b and disposed on either side of a projecting rib 31 carried by the bar lb.
The strip 2b is locked in its operative or fold-back position by the engagement of an in-turned lip 34 of hooksectioned projection 33 into a groove 35 formed to this end in the fixed rib 3l. Abutment means for holding the strip 2b in its waiting position (FIG. 7) are also provided.
These abutment means are particularly simple and efficient and consist of a shoulder-like cavity 36 formed in strip 2b and adapted to engage the upper edge 37 of the fixed bar 1b in the waiting or inoperative position of the strip. This movable strip 2b comprises on its rear face a cavity 38 adapted to receive any excess sheet material likely to lie behind the strip 2b after the corresponding edge of the hanging 21 has been secured to the needles 8. Moreover, to prevent the exertion of an excessive pull on these needles, which might tear or otherwise damage the hanging material, retaining stria or splines 39 are formed on the relevant end of the movable strip 2b.
As in the earlier described embodiments the pivoting strip 2b may consist of a continuous member. However, as illustrated diagrammatically in FIG. 8, this strip may also'consist of a plurality of separate elements 2c identical with, but shorter than, element 2b, these various elements 20 being secured in mutual alignment on a common fixed bar ld but with a certain relative spacing, as shown at E. Of course, the corresponding edge of the hanging 21d is fastened to the various successive elements 20 constituting the pivoting strip of the present device.
The use of these multi-section strips facilitates greatly the tensioning operation. In fact, it is possible to fold back in succession the various elements 2c. Thus, as shown in FIG. 8, the first element may be folded back to its vertical position against the wall P, as in the case of the left-hand element, while the next element 20 is still in its horizontal, inoperative position. Thus, the final tensioning operation is facilitated. In fact, if the pivoting strip consists of a single or continu ous element of relatively great length, this operation requires the intervention of two or more persons, for it must be performed in one and single movement. On the other hand, if the strip consists of a plurality of elements, a single operator can easily fix the hanging in several steps, by actuating in succession the various elements.
FIGS. 9 to 15 illustrate another embodiment of the device of this invention which is designed to this end. In this arrangement the pivoting strip also comprises three separate elements 2e between which free gaps are left. These elements 2e are pivoted to a common fixed bar 1e by means of a curved lip 40 formed on each element and rotatably engaging a matching'curved lip 41 formed on a projection of the corresponding fixed bar 12.
However, the several hinge elements 2e are interconnected by a flexible strip 42 consisting for example of an extruded section of deformable plastic material, which is secured to the elements 2e by hooking, with the assistance of a retaining rib 43.
On the face constituting the rear face in its end position the connecting strip 42 comprises a groove 44 engageable by a tape 45 carrying a series of needles 46 substituted for the preceding needles 8.
The various elements 2e of the movable strip can be lifted in succession. In fact, the flexible connecting strip 42 is adapted to be distorted between two adjacent elements 2e having different angular positions. However, this strip 42 constitutes a continuous support for the corresponding edge of the hanging 21e and this constitutes an advantage in comparison with the form of embodiment illustrated in FIG. 8.
Moreover, the flexible connecting strip 42 is also adapted to be bent in order to provide a continuous joint at a corner between two fixed bars also forming an angle with each other either in a single plane or in two different planes.
If desired, the fixed bar of the device of this invention could likewise be divided into a plurality of separate and spaced sections, like the movable strip. This embodiment would permit of forming an elbow with this device.
In the embodiment illustrated in FIGS. 9 to of the drawings the fixed bar 1e carries a strip 47 adapted to constitute a bearing member or abutment for a heel 48 formed on each element 22 of the pivoting strip when this element is in its operative or erected position. This strip 47 is formed integrally with a lip 49 projecting from the body of bar 1e. However, this strip 47 is relatively thin and therefore flexible, the material of bar 1e being selected accordingly.
When all the elements 2e have been brought to their operative or erected position, they are locked in this position by the engagement of their heels 48 against the strip 47 carried by the fixed bar 12.
These locking means facilitate greatly the subsequently removal of hanging 21e. In fact, it is only necessary to exert a pressure in the direction F on the strip 47 for causing same to retract, due to the resulting distorsion of its supporting lip 49, as illustrated in FIG. 13. This pressure may be exerted on the strip 47 by applying ones fingers against the hanging 2le at the proper location. When the strip 47 has thus been collapsed the heel 48 of the registering element 22 is no longer retained and this element will tend to tilt forwards in the direction of the arrow F, as illustrated in FIG. 14.
However, the elements 2e constituting the pivoting strip are retained in the inoperative position shown in FIG. 15 due to the provision of a small lip 52 acting as an abutment to heel 48, and also to the presence of the curved ledge 40 stressed against its companion lip 41.
Preferably, the edge of fixed bar 1e which lies on the side opposite to the location contemplated for receiving the pivoting strip 2e is formed with a rib 43c adapted to receive and retain a strip 42:; similar to strip 42 but opposed thereto to permit the fixing of a lining sheet e.
As illustrated in FIGS. 16 and 17, the fixing element provided with the needles 45 may advantageously be replaced by an element 45a carrying a row of needles 46a and 46b of unequal lengths. The purpose of these unequal lengths is to facilitate the engagement of the hanging thereon, as the fabric will engage firstly the longer needles. If desired, these longer needles may be provided with thicker retaining portions 53.
However, it will be readily understood by those conversant with the art that many other fastening members may be used in lieu of these needles.
FIGS. 18 to 20 illustrate another embodiment of the device according the invention, in which the movable strip is provided with other fastening means. This device comprises a bar lfsecured to the wall M to be covered and a strip 2f adapted to pivot on said bar. This strip 2f, which may consist of a plurality of component elements spaced from one another, all mounted on a common bar If, carries a flexible strip 42fconstituting the support proper for the upper edge of the hanging 21f to be fixed under tension in front of the wall M.
The flexible strip 42f has formed in its free end a groove 55 having its opening directed backwards when the molding is in its final raised position (see FIG. 2). The groove 55 thus contemplated is adapted to act as a recess for securing the corresponding edge 56 of the hanging 21 f. More particularly, this edge is wound over a reinforcing and thickening element adapted to be inserted into said groove, this element consisting for example of a flat strip 57.
In the final position in which the flexible strip 42f is folded back against the wall M, the median plane XX of the groove 55 forms an angle a with the vertical plane YY' containing the line 0 constituting the pivot axis of the strip 2f supporting the flexible strip 42f.
However, the inclinations of groove 55 may differ, the angle a being adapted to vary from 0 to 180. In this last instance, the groove 55 extends vertically when the flexible strip 42f is folded back to its end position and then the opening of this groove is turned upwards. But this is the limit permissible position of this groove 55.
In fact, preferably the opening of said groove should be directed backwards when the flexible strip 42f is folded back against the wall M, so that the tractive effort F exerted on the edge 56 of the hangings, due to the tensioning thereof, will cause this edge 56 to be wedged with its strip 57 in the groove 55. Under these conditions, the edge of the hangings is properly secured to the flexible strip 42f and cannot be released therefrom in spite of the tension exerted on the hanging. Now, this fastening action is obtained without resorting to any hooking points, thus eliminating any risk of dam aging or tearing the edge of the hangings, However, ribs or notches 58 are advantageously provided on the outer surface of the free end of the flexible strip 42fin order to increase the adherence of the hangings thereto.
The edge 56 of the hangings in the groove 55 can be positioned very easily when the flexible strip 42f is in its position away from the wall M (see FIG. 1). It is then only necessary to engage this edge into this groove after having folded same about the strip 57. Now the folding of flexible strip 42f back against the wall M will properly tension the hangings which cannot be subsequently released, considering the folding of its edge 56 and the fitting of this edge into the groove 55.
As will be seen in the drawings, the elements 2fconstituting the pivoting strip are pivoted to a section member 59 carried by the fixed bar If. This pivotal mounting is obtained by virtue of a pair of complementary curved edges 60 and 61 provided on this section and on the corresponding edge of the elements 2fconstituting the pivoting strip, respectively. More particularly, the marginal portions 61 of these elements are adapted to rotate about the curved ledge 60 of the fixed section 59.
This section 59 carries a stop 62 adapted to co-act with a pair of projecting heels 63 and 64 formed on the elements 2f of said movable strip. The first heel engages the stop 62 when the strip 2f is in its position away from bar It f, so as to retain said strip in this position (see FIG. 18).
As to the other heel 64, it engages the stop 62 when the strip 2f is folded back, so as to hold this strip likewise in this second position (see FIG. 19). But in this last case the locking of the elements 2f of the pivoting strip is completed by a hook 65 carried by these elements and adapted to engage a retaining hook 66 carried by the fixed section 59. Moreover, in the open position illustrated in FIG. 1 the locking of the component elements 2f of the pivoting strip is also completed by another stop 67 engageable by the heel 64 formed on these elements.
Preferably, the fixed bar If comprises a groove 68 adapted to constitute a means for securing the edge 69 of a lining 20f disposed behind the hangings 21f. The edge of this lining 20f is then wound over a thickness strip 57f in the same manner as the edge of the hangings proper.
FIG. 20 illustrates a modified form of embodiment of the moulding adapted to act as a support to the corresponding edge of the hangings to be secured in position. The corresponding flexible strip 42g departs from the preceding one in that, in addition to the groove 55 provided therein, it comprises a second similar groove 55g having a different inclination. Moreover, this groove has also a different width.
Thus, according to the specific arrangement contemplated, one may use one or the other of these two grooves for fastening in position the corresponding edge of the hangings 21 f by providing or not a reinforcing and thickening element such as said strip 57.
But, of course, the fixing device according to this invention is liable to be embodied with many other modifications and variations, without departing from the basic principles of the invention as set forth in the appended claims.
Further, the device of this invention is adapted to be used in many different applications. As already mentioned in the foregoing, this device may be used for fixing in position a textile or fabric sheet, or any other lining material, against a wall. But it is clear that it could be used as well for securing a similar lining tapestry or upholstery material to any other surfaces, such as ceilings or floors.
