Definitions

  • This invention generally relates to stretcher frames used by artists to mount canvas and other fabrics thereon prior to working on such fabrics.
  • Painters have traditionally mounted their canvases on rectangularly shaped wood frames by pulling the canvas tautly over the edge of the wooden frame and then tacking or stapling the edge of the canvas to the back side of the wood frame. Similar frames have also been used to mount silk and nylon fabric for silk screening.
  • the tacks and staples tend to damage the fabric when mounting and removing the fabric from the frame.
  • the mounting tends to be permanent because of the inconvenience of removing the tacks and staples in order to remove the fabric from the frame.
  • GB 357653 discloses a frame or stretcher for canvas in which the members forming the top, bottom and sides of the frame have a rabbet around their inner edges into which edge portions may be extended of a piece of canvas stretched over the frame and pulled around the outer edges of the frame members.
  • the edge portions of the canvas are clamped in the rabbet by fillets of form complementary with the rabbet and which fillets are held in place by clips extended over the fillets and the adjoining inner edges of the frame members.
  • the frame, and the manner of securing the ends of the frame members together, are otherwise conventional and ill-suited to assembly by unskilled hands.
  • the manner of fitting the canvas to the amended frame likewise requires some skill.
  • US 3625274 discloses a canvas stretcher which comprises tubular frame members interconnected by angled elements the limbs of which are received in the open ends of the tubular frame members.
  • the frame members have, on their rear sides, longitudinal channels to receive edge portions of the canvas applied to the frame, which edge portions are held in place by deformable plastics insert strips subsequently inserted in said channels.
  • This stretcher like that of GB 357653 is not readily assembled and used by students and others who may not have the manual dexterity to assemble a conventional stretcher frame and to mount fabric thereon.
  • a stretcher frame assembly for mounting a sheet of fabric
  • the assembly including a frame structure comprising a plurality of interconnected frame sections so secured together at their ends as to prevent relative rotational movement between said frame sections, said frame structure defining a front plane and said frame sections having portions, disposed rearwardly of said front plane and projecting inwardly, and thus towards the middle of the frame, the assembly including clamping means whereby, in use, a sheet of fabric can be stretched tautly over said frame structure so that a central portion of said sheet lies in said first plane and edge portions of said sheet extend around said frame sections, and whereby such edge portions can be secured to said inwardly projecting portions of said frame sections by said clamping means, characterised in that said inwardly projecting portions of said frame sections are in the form of ridges which project inwardly from the respective frame sections and said clamping means are adapted to fit over said ridges after such edge portions of the fabric have been wrapped over such ridges, whereby said edge portions are clamped to the front and
  • the clamping means preferably comprises a plurality of individual clips on each frame section, for it is difficult to maintain the desired uniform tension on an entire side of the fabric if only one elongated clipping element is used to secure the one side of the fabric to the ridge on an individual frame section.
  • one edge of the fabric is pulled over the ridge and clips are applied thereto to secure the fabric to the frame section.
  • the opposite edge of the fabric is pulled tautly over the ridge on the opposite frame section and clipped thereto to secure the fabric thereto.
  • the adjacent sides of the fabric are attached in the same or similar manner.
  • the fabric is pulled tautly and clipped to the ridge at a plurality of points along the length of each frame section in order to provide the desired tension to the fabric along this edge thereof.
  • the clips are merely disengaged from the ridge and the fabric and the frame separated.
  • the ridges on the individual frame sections are preferably parallel to the plane of the frame and/or fabric mounted thereon so that when the clips are employed to secure the fabric to the ridge, the clips did not project outwardly beyond the back plane of the frame.
  • FIGS 1, 2 and 4 illustrate an annular stretcher frame assembly 10 embodying features of the invention.
  • the stretcher frame 10 assembly comprises frame sections 11 interconnected by means of elbows 12.
  • a plurality of clips 13 secure fabric 14 onto the ridge elements 15 on the inner side of frame sections 11.
  • Figures 1 and 2 best illustrate securing the fabric 14 to the ridge 15 by means of the spring clips 13.
  • the ridge 15 projects inwardly toward the centre of the annular frame 10 and is generally parallel to the plane thereof.
  • the fabric 14 is mounted on frame 10 with the clips 13 positioned out of the way so that they do not become disengaged from the ridge 15, or otherwise interfere with the subsequent handling of the stretcher frame assembly 10. Slight deviations from the parallel relationship could be accommodated provided that the ridge 15 or clip 13 do not project beyond the back plane of the frame assembly 10.
  • FIG. 5 An alternative frame section 20 is shown in Figure 5 which has a plurality of ridges or projections 21 along the length thereof in those areas where the spring clips 13 are to be used to secure the fabric 14 to the ridges 21.
  • Figures 2 and 3 illustrate the stretcher frame assembly 10 with fabric 14 mounted thereon in conjunction with a display frame 30.
  • the inner surface or contact points of the display frame 30 match the outer surface of the stretcher frame assembly 10 so that the fabric 14 can be displayed while still mounted on the stretcher frame 10.
  • Suitable means are provided along the outer edge of the display frame 30 to fit over the back side of the stretcher frame 10 to hold the stretcher frame assembly 10 and the display frame 30 together.
  • the mountings of the edges of the fabric 14 to the ridges 15 by means of clips 13 are most important on those sides of the stretcher frame where the fabric is pulled tautly over the ridge 15 to put the proper tension on the fabric.
  • Other means may be employed to initially mount the fabric on the opposite sides of the stretcher frame. With rectangular shaped frame assemblies at least two adjacent frame sections must be provided with inner ridges suitable for securing the fabric thereto by clips.
  • the stretcher frame assembly 10 can be made as a breakdown unit comprising standard corner sections or elbows 12 with frame sections 11 of various lengths in order to form stretcher frames in a wide variety of sizes. It is also contemplated that the stretcher frame of the invention may take the shape other than rectangular, in which case the corner sections or elbows 12 may have an angle other than 90°. The ends of the corner sections or elbows 12 may be provided with ridges 35 which interfit grooves 36 provided on the interiors of the frame section 11 to properly lock the individual frame sections 11 into position with the elbows 12 when assembling the stretcher frame components to prevent relative rotation thereof.
  • the stretcher frame 10 and the elbows 12 of the invention can be formed of any suitable plastic, metal or wood materials or combinations thereof.
  • Plastic material such as polyethylene is preferred because it can be easily and inexpensively produced by extruding.
  • the ridge can be extended integrally therein.
  • the cross-section of the frame sections 11 while shown hollow and circular in the drawings, may be of any convenient cross-sectional shape and moreover, may be solid instead of hollow as shown.
  • the ridge 15 is shown in the drawings as being integral with the frame section 11; however, the ridge may be a separate element and attached or fixed to the frame section 10 by suitable means.
  • the stretcher frames of the invention are most suitable for use in art classes where the stretcher frames may be frequently reused by the students, particularly when the frames are made as breakdown units.
  • clipping means have been described herein in terms of spring clips, it is obvious that different types of clipping means can be employed.
