Definitions

  • the present invention relates to a frame for a painter's canvas, or other fabrics.
  • One of the main problems encountered in the production of frames for painter's canvas is to allow the fixing of a canvas under a tension as uniformly distributed as possible.
  • FR-A-2 505 020 describes a frame (or frame) made up of several sections along a rectangular contour, the sections comprising at least one U-shaped groove along one of their edges.
  • a canvas is arranged on the frame, the edge of which is received in the grooves, and thick blades are forcefully engaged in the grooves.
  • the frames are made of wood and the canvas is fixed under tension and maintained by gluing or nailing.
  • these are delicate or time-consuming techniques.
  • it is extremely difficult, if not impossible, to detach the canvas from the chassis in order to fix it on another chassis if this proves necessary.
  • the present invention relates to a chassis made up of several sections assembled according to a selected polygonal contour, said sections being formed by profiles having at least one longitudinal groove along one of their peripheral edges, said groove being susceptible to receive an edge of a fabric arranged on said chassis, and a tensioning device of elongated shape, extending over the entire perimeter of the chassis, and held in force in said groove, characterized in that the walls of the peripheral edge of the profiled delimiting said groove have end portions defining a narrowed mouth for said groove and in that the tensioning device consists of an elongated rod comprising a flat base intended to come to bear against the end portions outside of the groove and of which the width is greater than that of the narrowed mouth and two parallel wings projecting from said flat base and having on their opposite faces beads intended to snap into said mouth.
  • the flat base of the rod has two ribs extending on the same side as the wings and outside of them, intended to come to bear against the end portions of the walls of said groove.
  • the chassis comprises a removable covering frame of C-shaped section with two slightly converging branches, fitted around the profile, and comprising on one side a covering lip projecting towards the interior of the chassis, in order to hide the tensioning rod as well as the margins of the fabric.
  • the two branches of the profile terminate in two re-entrant claws which engage between the edges of the flat base of the strip and the profile, beyond the ribs.
  • the present invention also relates to a frame made up of several sections assembled according to a selected polygonal contour, said sections being formed by profiles having at least one longitudinal groove along one of their edges, said groove being capable of receiving a border of a fabric disposed on said chassis, and a tensioning device of elongated shape, extending over the entire perimeter of the chassis, and held in force in said groove, characterized in that said groove has a narrowed mouth and the tensioning device consists in a resiliently deformable loop band, of width substantially equal to that of the groove.
  • the tensioning device consists of an elongate elastic seal with a section substantially complementary to that of the groove.
  • the installation steps are particularly simple and do not require any tools or special knack.
  • the canvas can be detached from the frame just as easily.
  • the groove has a U-shaped or V-shaped section and the tensioning device consists of a single band in closed loop, forcibly engaged in the groove, either by its own elasticity, or by means a tensioner.
  • the profile will have two parallel grooves, which will allow to stretch two fabrics on the frame, one on the front, the other on the back.
  • the profile can be shaped, on the side of the inner edge of the chassis, in the form of a rail, as taught in patent application FR 86 11261, which will allow a multiplicity of sliders to be received. and arrange any canvas around with a zig-zag cord.
  • a covering profile with a C-shaped section can be fitted around the entire periphery of the fabric on the chassis.
  • Each chassis section consists of a hollow section defining an internal rail 16 opening out through a slot 18 on the internal edge of the chassis.
  • the profile On its face opposite to the slot 18, that is to say on the outer edge of the chassis, the profile has two grooves 20, 22 of substantially semi-circular section and opening out through a narrowed mouth 24. The grooves extend over the entire length of the sections of the profile.
  • the chassis also comprises a tensioning device in the form of an elongated elastic seal 26 of section substantially complementary to that of the groove 20, 22, therefore in this embodiment, a circular section as illustrated in FIG. 1.
  • the fabric border is also forced into penetration in the groove, which has the effect of fixing the canvas on the frame under a uniformly distributed tension, once the seal has been introduced into the grooves of all the sections of the profile.
  • the seal can be in one piece and cover the entire perimeter of the chassis, or even be formed of a succession of sections of the same length as the sections of sections.
  • the canvas 28 can consist of a painter's canvas, without it being a limiting application. It may consist of a decorative canvas or not, of textile material, or any other flexible sheet material.
  • the periphery of the chassis can be garnished with a covering profile 32 with a C or L-shaped section, simply fitted around the sections of profiles of the chassis.
  • FIG. 3 the use of the chassis has been briefly illustrated according to the teachings of application FR 86 11261.
  • a number of sliders 40 are arranged in the internal part forming a rail 16. These sliders end, outside of the slot 18, by eyelets 42 which are used for the establishment of a tensioning cord 44 arranged in a zig-zag between the eyelets 46 of the fabric 48 and the eyelets 42 of the slides.
  • the grooves 20 and 22 of the profile are unused and it is also possible to provide a covering frame 32 in order to hide the sections of the chassis and the slides.
  • FIG. 4 a connecting piece, or a square 50, is illustrated, allowing the connection between two consecutive sections of profile 10 and 12.
  • the bracket 50 has two wings 52 and 54 which fit inside the hollow sections and which carry two screws 56, 58 for holding. When the two sections are fitted onto the bracket 50, the screws 56, 58 are tightened through the slot 18 and the screws maintain the profiles by bracing at the bottom of the internal cavity of the profiles.
  • angle separating the wings of the bracket 50 may be different from 90 ° as illustrated and we could provide a series of brackets having wings separated by different angles in order to create frames having virtually any polygonal shape.
  • the tensioning device can consist of a loop band as in the previous case, or a joint of the type described in relation to the other embodiments and forming a closed loop.
  • the groove may be provided along the profile edge corresponding to one of the faces of the frame, as illustrated in FIG. 6.
  • the profile used to form the chassis has a section of the type of that illustrated in FIG. 5.
  • the central part 11 of the profile 10 forms a hollow rectangle and from two adjacent vertices project two walls 60, 62 which together define a groove 20, of trapezoidal section.
  • the two walls have an initial part (60a, 62a) slightly inclined towards the outside, along the inclined edges of the trapezoid, and a terminal part (60b, 62b) extending inwards along the large base of the trapezoid, the narrowed mouth 24 of the groove 20 being defined between the ends of the end parts (60b, 62b) of the two walls 60, 62.
  • the profile 10 is preferably made of metal, advantageously aluminum.
  • the tensioning device 26 consists of an elongated strip 64 comprising a flat base 66, of width greater than that of the narrowed mouth and two parallel wings 68, 70 projecting under the flat base 66.
  • the two wings 68, 70 have on their opposite faces of the beads 72, 74 or hooking claws which snap under the ends of the walls of the profile 10 by elastic deformation of the two wings, by trapping the fabric 28 stretched on the frame.
  • This embodiment makes it possible to use fabrics 28 of different thicknesses while ensuring correct tension, thanks to the elasticity of the wings 68, 70 of the strip 64.
  • the profile sections 10 are assembled so that the groove 20 is disposed on the outer edge of the chassis.
  • the fabric 28 is placed on the chassis, the edge of the fabric falling along the outer edges facing the mouth 24 of the grooves 20.
  • the rods 64 are then forced into the grooves 20, driving the edges of the canvas , until the beads 72, 74 snap under the ends (60b, 62b) of the walls of the profile which define the narrowed mouth 24 of the groove 20.
  • the tensioning rod 64 locally traps three layers of fabric, which is facilitated by the configuration of the rod.
  • the fabric 28 is supported along the extreme periphery of the chassis, substantially on an edge 76, which avoids the problems of paint burrs between the fabric 28 and the frame 10.
  • the flat base 66 of the rod has two ribs 78, 80 on the same side as the wings 68, 70 and outside of them, intended to come into abutment against the end portions 60b, 62b , of the walls of the groove 20.
  • the covering frame 32 of the chassis consists of a C-shaped profile 82 with two branches 84, 86 slightly converging, fitted around the frame profile 10, and having on one side a covering lip 88 projecting towards the inside of the frame, in order to hide the tensioning rod 64 as well as the margins of the fabric 28.
  • the covering frame 32 is practically independent of the chassis which can deform freely, while the oblique cuts at the corners of the covering frame can remain perfectly contiguous in all circumstances.
  • the profile 82 of the covering frame is held on the edges of the tensioning strips 64.
  • the two branches 84, 86 of the profile terminate in two re-entrant claws 90, 72 which engage between the edges of the flat base 66 of the strip and the chassis profile, beyond the ribs 78, 80 .
  • the invention is not limited to a frame in which the profiles are provided with a groove and the tensioning device is received in the groove, but also covers a frame in which the profiles are provided with a projecting rib and the tensioning device has a groove which covers this rib.
