Definitions

  • This invention relates to a support and mounting for fabric, paper or other flexible material. It is particularly suited to support artists materials so that the artist can work on them or so that they can be displayed.
  • U.S. Patent 5,007,188 issued to one of the inventors herein describes a mount suitable for assembly into a frame for supporting fabric or paper material particularly for use by artists.
  • the mount includes a channel portion into which styrene foam board or the like is receivable; the side wall of the channel portion has an upwardly open slot into which the fabric is tucked and retained.
  • Means for supporting a decorative frame to surround the mounted fabric are also provided.
  • the present invention seeks to provide a mounting device which remedies these disadvantages.
  • the present invention comprises mounting devices for mounting a sheet material in a substantially flat manner, in order to minimize creases, while maximizing the life of the material.
  • a variety of sheet materials can be accommodated, including canvas, paper, or the like. Suitably, it can be used to support an artist's work while he is drawing or painting on it, and can also mount the finished work afterwards.
  • the mounting device holds a support board, typically a foam board or panel, to help support the sheet material.
  • the sheet material is stretched over the top of the mount and around a smoothly curved portion of the mount. An edge or border region of the material is retained in a recess in the side or bottom of the mount.
  • the mount components are extruded from a resilient material in order to assist in the retaining of both the support board and the material.
  • the mounting device and the support board are formed as a unitary piece.
  • the mounting member may also be provided with doubled walls and cross pieces in cross section to add rigidity if desired.
  • the mounting device holds the support board with a top wall and a bottom wall, which are joined together by a side wall to make a C-shaped recess.
  • the top wall is tapered, although this is not necessary particularly if the supported material does not lie against it.
  • the bottom wall is substantially parallel to the top wall proximate to the side wall, but then curves slightly towards the top wall, and then back down, in order to increase the resiliency of the said bottom wall, in order to more effectively retain the support board.
  • the bottom wall may also be tapered, and in certain embodiments, may even be substantially a mirror image of the top wall.
  • the material retaining recess can be narrow slots into which the material is folded, or wider slots for retaining the material in cooperation with elongated splines.
  • Sheet material retaining means such as ribs, teeth or other retaining protrusions extend inwards from retaining slots in order to assist in gripping the sheet material, and are angled to make it difficult to withdraw.
  • the sheet material may be wrapped around a spline, which is in turn stuffed into a retaining slot.
  • a variety of recesses may be used, as hereinafter described. Some embodiments are combination mounts with more then one slot, which adds flexibility in their use. In practice with these combination mounts, only one of the recesses would normally be used, the choice depending upon the size of the mounting frame and the weight and thickness of the sheet material. However, in certain circumstances, more then one of the recesses of these combination embodiments may be used.
  • the curved corner in the preferred embodiment, an upwardly protruding short wall terminating in a smoothly curved lip extending upwards and inwards from the outward edge of the upper wall.
  • the sheet material can be wrapped over this lip and curved downwardly towards and into the material retaining recesses.
  • the sheet material is preferably pushed into the recesses sufficiently to provide a slight stretching or tension over the lip, to smooth out creases.
  • An optional hard or soft sheet may be placed in between the sheet material and the top wall to support the material. This is useful, for example, to provide a backing for paper on which an artist wishes to sketch.
  • the slots may be oriented either downwardly or sideways in the direction remote from the support board.
  • the mounting device can cooperate so as to accommodate varying sizes of the material.
  • Mounting devices can be positioned to form a rectangle so as to retain all four edges of square or rectangular sheet material.
  • non rectangular materials can be mounted, using a series of components around the perimeter of the material. Corners can be connected by providing suitable diagonal edges on the mount devices. If the support board is longer than the mounting device mount devices may be combined by placing them side by side so that each cooperatively retains the support board. Furthermore, if the mounting device is longer than the support board sheets of support board may be secured side by side by having one mount receive a portion of each. In addition, curved materials may be so mounted by appropriately notching the components.
  • a preferred embodiment eliminates the need for assembling components of the mounting around a support board received by a channel of each component.
  • a single one piece support board has sheet material retaining recesses around its periphery.
  • this embodiment would be constructed as a one piece injection molded article from a suitable plastic material.
  • the sheet material preferably would be held substantially flat above the supporting board, by stretching the outer edges of the material around a curved corner of the peripheral edges of the support board, or over an upstanding lip extending upwardly therefrom.
  • the peripheral edges or upstanding lip must of course be smoothly curved so that the material does not tear.
  • Sheet material retaining recesses are located underneath the periphery of the said support board or on the exterior sides of it.
  • the said support board is flat on both sides, and the non- supporting surface could be reinforced. In one embodiment this is accomplished by constructing the support board with raised reinforcing ridges which emanate outwards from a central circular ridge on the said non supporting surface.
  • an additional support material either hard or soft, could be laid flat intermediate the support board and the sheet material.

  • the term “smoothly curved" in this disclosure is applied to corners, lips or protrusions over which the sheet material is intended to be stretched.
  • the term is intended to mean a corner or protrusion which does not have a sharp or angular protrusion which would cut or cause wear to the type of material with which it is intended to be used.
  • the corner or protrusion is to have a gentle, gradual transition in direction, as for example from the horizontal to the vertical.
  • this can be done by providing the corner or protrusion with the cross sectioned profile of a segment of a circle. For example, a transition from horizontal to vertical could be accomplished by a profile of a quarter circle.
  • the radius of the circle is not critical, provided it is sufficiently large so that the particular material being used is not torn or cut or worn by the stretching over it.
  • smooth transitional shapes other than circular can be used as well: the important thing is to avoid sharp corners which would tear the material.
  • Mount 10 is elongated in the axial direction and will normally be manufactured as a continuous extrusion.
  • FIGURE 1a shows three separate pieces of mount 10, numbered as
  • FIG. 10 10', 10", 10 ih assembled around support board 20.
  • Arrow 200 shows how mount 10'" can be assembled onto support board 20, wherein edge 20'" is forced into channel 18'".
  • Each mount component can be appropriately mitered at its axial ends for cooperative placement with other components, as shown at 100 and 101.
  • FIGURE 1b shows an enlarged cross section of a mount from FIGURE 1a.
  • Mount 10 comprises a top wall 12, bottom wall 14, and a side wall 16, which interconnects the top and bottom walls to form therewith a generally rectangular C shaped channel 18.
  • Upper wall 12 extends beyond side wall 16 and terminates at the upper end of downwardly extending member 24 and upwardly extending lip 28.
  • Lip 28 is smoothly curved at 26 to assist in guiding material 60 originally in a substantially horizontal plane above wall 12, around lip 28, into a substantially orthogonal plane outwards of member 24 as shown in FIGURE 1c.
  • a wall 40 depends downwardly from upper wall 12, intermediate of members 24 and 16, and preferably closer to member 24, forming two recesses of unequal width, here comprising a narrow recess 42 between members 24 and 40 and a wide recess 44 between members 40 and 16.
  • Wall 40 curves upwards at 46 to form upwardly extending wall 34, in same vertical plane as 24.
  • Member 45 is smoothly curved to allow material 60 to be wrapped around member 45 and thence to pass into recess 44.
  • a pair of transversely opposed shoulders 46 is provided respectively disposed on side wall 16 and intermediate wall 40 to form a slot 48 which locates adjacent the upper end of the wider of the recesses (recess 44).
  • Slot 48 permits the insertion of an angle bracket to provide bracing where two members 10 (for example 10" and 10'") are joined to form a frame.
  • Each recess 42, 44 may have one or more ribs associated therewith for gripping material 60 which is forced into the recesses. These ribs may take different forms.
  • mount 10 is formed from a resilient material and in recess 44, gripping ribs 52 take the form of small protrusions which project into the recess from the walls on each lateral side thereof to assist in gripping.
  • Recess 42 does not have any ribs in the embodiment shown.
  • FIGURE 1c shows the mount 10 in one mode of operation, with support board 20 received into channel 18.
  • Bottom wall 14 is shown to be curved and preferably resilient in order to grip and retain support board 20.
  • An optional sheet 64 is shown above support board 20 and upper wall 12, in order to offer additional support to material 60 above. This sheet is not necessary, s the material 6 may merely be stretched between curved lips 26. However, it is preferred in cases where an artist will be sketching on material 60, particularly when the material is a relatively fragile one such as paper.
  • Upper wall 12 may be optionally tapered at its inward end and sheet 64 is provided with a complementary taper.
  • the material 60 is shown to be stretched above sheet 64, and then wrapped around curve 26, vertically across the outer faces of members 24 and 34 and around curve 46 and into recess 44 to be retained.
  • This wrapping around serves to hold the horizontal face of sheet material 60 under tension to prevent creases.
  • the sheet material 60 is retained by partially wrapping sheet material 60 around a spline 80, which is then inserted into recess 44.
  • the spline 80 is constructed from a resilient material. The resilience of the spline, and of the walls 40 and 16 and the gripping ribs 52 all cooperate in this embodiment to retain sheet material 60, and prevent slippage in order to ensure a desired degree of tension in the sheet material 60.
  • FIGURE 1d another mode of operation is shown for the same structure.
  • sheet material 60 is shown to be stretched above sheet 64, and then wrapped around curve 26, vertically across the outer face of member 24 and then upwards into recess 42 to be retained by wedging action of spline 85.
  • FIGURE 1e shows a modified version of the embodiment of FIGURE 1 , which does not require the cooperation of a spline in order to retain the sheet material.
  • Differences between this modified version and that of FIGURE 1 include narrower recesses, and the addition of teeth or other gripping protrusions 49 extending into cavity 42. Shoulders 46 defining slot 48 are eliminated, and side wall 16 is modified. Consequently, transverse wall 47, extending inward intermediate from wall 40, supports a shorter (then FIGURE 1) downward depending side wall 16 1 , which in turn supports inwardly depending bottom wall 14 at the lower end of 16'.
  • walls 12, 47 and 14 are substantially horizontal.
  • FIGURE 1f shows this modified mount in the two modes of operation corresponding to FIGURES 1c and 1d.

  • Intermediate wall 216 and end of wall 214, lower wall 214 indents towards wall 212, in order to increase its resiliency in order to better retain the support board.
  • both walls 212 and 214 are tapered, and gripping ridges 256 extend centrally from both walls 212 and 214.

  • outwardly open recess 242 is formed between upper wall 212 and traverse wall 264
  • downwardly open recess 244 is formed between walls 262 and 276.
  • recesses 244 and 242 include gripping ribs 252, in the form of small protrusions which project into the recess from the walls thereof, to assist in gripping.
  • an open ended box structure 270 is formed by the walls 216, 272, 273 and 276 serving to stiffen mount 10, without compromising the resiliency of the walls forming recess 242, or the channel 218.

  • Upper wall 212 has sheet material guiding means, which in the embodiment shown in FIGURE 2, comprises end member 224, having upwardly and inwardly curved portion 228, with smoothly sheet 226 and 227 for angling the material into recess 242, shown by angled edge 227.
  • FIGURE 2c shows the mount 210 in one mode of operation, with support board 20 received into channel 218.
  • the material 60 is shown to be stretched above optional sheet 64, and then wrapped over member 228, around curve 226, vertically downward across the faces 224 and 262 and upwards into recess 244 to be retained.

  • Walls 216' and 272' engage the bottom and top edges of support board 20 respectively.
  • Outwardly opening retaining slot 242' is narrower then slot 242, in order for transverse wall 264', in cooperation with upper wall 212, along with gripping ribs 252, to retain the material wedged within slot 242'.
  • wall 276' depending downward from transverse wall 264' is shifted closer to downward wall 262', making downward open retaining slot 244' narrower then corresponding slot 244 of the spline using embodiment of FIGURE 2.

  • the distal end of the side wall portion 116b terminates in the plane of the lower surface of lip 160, which plane is vertically spaced apart beneath distal portions of the divider wall 140 and outer side wall 124.
  • FIGURE 11 axial ends of portions of the mount are mitered as at (FIGURE 11).
  • the portions are assembled onto a suitably dimensioned portion of foam board F, which is forced into channels 118.
  • the adjacent corner portions of mount 110 are reinforced with a pair of L shaped braces B which are respectively received in slots 136 and 148. Grub screws G lock the lower of the braces B in position.
  • FIGURE 11 is somewhat figurative in that the end of a mount portion 110 into which the L shaped braces are shown as being inserted is square cut, and not mitered. This is for ease of illustration; however, adjacent portions of square cut mount may be joined in the same manner as the corners by using straight braces (not shown).
  • box 130 itself may serve as a slot into which a brace may be inserted for joining abutting portions of mount 110 together.
  • a tucking tool T has a hooked end which engages behind lip 160, and a projection P which locates to urge fabric material M into the wider of the grooves, groove 144.
  • a reinforcing spline S may be employed. While fabric material M is shown as being received in both the narrow groove 142 and the wide groove 144, in practise one or other of the grooves would normally be used, the choice depending upon the size of the mounting frame and the weight and thickness of the fabric material M.
  • the tucking tool T may also be used to force fabric into narrow slot 142. The use of tucking tool T permits the ready adjustment of the tension applied to fabric material M.
  • a decorative frame is easily supported from the mounting frame.
  • a decorative extruded frame element E is supported from mount 110 using simple wire clips C, seen also in FIGURE 15, which secure to the mount by means of headed screws H which are received in trench 120 at intervals as desired.
  • Clip C beds firmly onto the small platform provided by the lower edge of lip 160 and the distal end of wall portion 116b.
  • a simple modification of clip C, as seen in FIGURE 16 suffices to permit decorative wood frames W to be supported from mount 110 as seen in FIGURE 14.
  • FIGURES 17 and 18 A second embodiment of the invention is illustrated in FIGURES 17 and 18, wherein the mount is identified by the numeral 1110.
  • the salient difference between the embodiments resides in the provisions in the second embodiment of a divider wall 1140 that is attachably secured to the remaining structural wall elements by means of cooperating hook elements 1141 , 1143.
  • Mount 1110 may be formed as a composite structure in the sense that divider wall 1140 may conveniently be formed of a resilient plastic material, and the remaining elements formed from a substantially non-deformable material for example aluminum, which is preferred by some art curators. Due to the increased stiffness of aluminum in comparison to most thermoplastic materials, I find that the transverse wall 128 and slot 136 the first embodiment may be eliminated.
  • top and bottom walls 1112, 1114 of this second embodiment can exert a strong compressive force on foam board F without themselves being undesirably thick.
  • a localized compressive force is preferably generated by pivoting an upstanding ridge 1115 on bottom wall 1114.
  • a further difference in the two embodiments which are equally applicable irrespective of the material of construction are the location of the upper portion of side wall 1116 which is the second embodiment is more outwardly located to define in pat a small inwardly opening channel 1119 within main channel 1118, the small channel permitting the use of foam board F of reduced thickness. Additionally a bead 121 is provided on top wall 1112 at its juncture with side wall 1124, which serves to raise fabric M above top wall 1112 over its whole width, so as to avoid any noticeable ridge on the mounted fabric as may be seen in FIGURE 19 for example.
  • FIGURE 10 illustrates a mount 1210 which is particularly suitable for extrusion in aluminum.
  • a divider wall 1240 is unitarily formed with the remaining wall structure and is resiliently sprung therefrom to permit an adequate degree of movement of distal end 1250 by increasing the effective length of the divider wall, whereby its proximal end roots to side wall 1216 at 1251.

Abstract

Un élément de montage, destiné à un matériau en forme de feuille souple tel que du papier à dessin ou une toile d'artiste, comporte des encoches de maintien (244, 242) dans sa partie inférieure ou latérale et un angle arrondi (226) (éventuellement doté d'un rebord) dans sa partie supérieure. Cet élément de montage présente un creux destiné à maintenir une planche de support ou bien il constitue un tout avec cette planche. Pour les utiliser, on assemble de tels éléments de montage sur les bords d'une planche de support s'ils ne constituent pas un tout avec elle. Cette planche de support peut éventuellement supporter une planche de renforcement. Un matériau en forme de feuille souple est tendu sur les angles arrondis des éléments de montage et sur cette éventuelle planche de renforcement. Les bords de ce matériau souple sont maintenus en place dans les encoches de maintien.
