Definitions

  • the present invention relates to a frame for a picture holder comprising four pairs of opposing sides.
  • the frame in accordance with the invention is intended as decoration on frameless picture holders, so-called clip frames, which consist of a backing piece and a sheet of glass, between which the picture and a slip mount, if any, are laid, and fixing elements in the form of loose clips, which can be caused to hold together the sheet of glass and the backing piece so that the picture is held in place.
  • the clips function as leaf springs, which have a hooked form at one end that engages around a piece of the front edge of the glass and the outer edge of the backing piece, and which, at the other end, are snapped securely into a recess in the backing piece intended for the purpose.
  • the clips are so designed as to permit each of them to function as a hanging arrangement having the ability to support the weight of the clip frame and to be hung from, for example, a picture hook, nail or similar.
  • the idea of invention is to enable an existing framing executed with a clip frame to be transformed at little cost into a framing of a more conventional and lavish kind, i.e. with a decorative frame.
  • Decorative frames for use on clip frames are previously disclosed through, for example, document DE 298 11 195 relating to a frame, which, by means of fixing pads in the form of double-sided adhesive tape, can be applied on the outside of a clip frame on the front side of the glass.
  • the frame can appropriately be manufactured from wood, although metal or plastic are also conceivable. A series of disadvantages are nevertheless associated with the described decorative frame.
  • the major disadvantage is the use of tape, since tape has a number of inherent disadvantages.
  • the strength of the tape usually decreases after a time, and this is associated with the risk of the decorative frame gradually sliding, working loose and falling off.
  • precision is required to ensure that the decorative frame is aligned correctly over the sheet of glass at the time of assembly. If the frame and the sheet of glass are mutually misaligned, it is then difficult to remove the frame and repeat the assembly procedure.
  • the means of hanging the clip frame is relatively weak, as it usually consists of one of the clips that hold the frame together.
  • the means of hanging can thus be assumed to be dimensioned only for the weight represented by the clip frame with the picture and the slip mount. If a decorative frame is then applied to the clip frame, for example made of metal as proposed above, the final framing will probably be significantly heavier, a consequence of which is that the hanging clip will presumably not be sufficiently strong for the intended purpose and a new, stronger hanging arrangement will be required.
  • This decorative frame which can be in wood, metal or plastic, for example, is arranged around the outer edge of a clip frame by means of leaf springs secured to the decorative frame.
  • the problem with this type of decorative frame is similar to the above in respect of the weight of the final framing.
  • Another disadvantage is that a frame of this kind consists of a number of parts, because of the leaf springs, which makes assembly and disassembly unnecessarily difficult, the consequence of which is that, among other things, a stage must be included in the manufacturing process in which the spring arrangements are manufactured and attached, and that the frame probably must be packaged in conjunction with its transport and sale. Including the cost of this, plus the cost of materials such as wood and metal, it can be assumed that this decorative frame, like that described above, will be as expensive as a traditional frame.
  • the object of the invention is thus to make available a frame for use as decoration on frameless picture holders such as clip frames, which frame comprises very few parts, is easy to assemble and disassemble on the clip frame, has a low weight, and is inexpensive to manufacture.

  • Fig. 2 shows an exploded drawing viewed from the rear of the clip frame and the frame in accordance with Fig. 1

  • Fig. 4 shows a cross section of the frame in accordance with a third embodiment
  • Fig. 5 shows a drawing viewed from the rear of a fourth embodiment of the invention.
  • Fig. 6 shows a drawing viewed from the rear of a fifth embodiment of the invention.
  • the present invention relates to a frame, in its entirety designated as 10, intended specifically for use as decoration on frameless picture holders such as clip frames 12, which invention is described below with the help of a number of illustrative embodiments.
  • a clip frame 12 consists of a backing piece 14 and a glass 16 and clips 18 which press together the backing piece 14 and the glass 16 with a picture and possibly a slip mount in between.
  • Clip frames 12 are available in a large number of standard sizes, although all exhibit essentially the same thickness before the picture has been installed.
  • the clips 18, which act as leaf springs and are relatively small, are arranged with the help of a hook-formed part at a number of points around the outer edge 20 of the clip frame and are snapped securely into recesses 22 in the backing piece. In this way a piece of each clip 18 is visible on the front side 24 of the frame 12.
  • the concept of the decorative frame 10 in accordance with the invention is that it must only consist of a single part, i.e.
  • Figs, la, lb and 2 Illustrated in Figs, la, lb and 2 is a first illustrative embodiment of the invention, in which the clips 18 are not visible from the front, and in which the frame, along its inner edge 34, is arranged with a peripheral recess in the form of a shoulder 32.
  • the frame 10 consists of a plate 26 with a thickness which essentially is greater than the combined thickness of the clip frame 12. The thickness can be the same or smaller, however. Depending on the design and the standard dimensions of the clip frame 12, on which the decorative frame 10 is to fit, the length and width dimensions of the plate may vary significantly.
  • a transcurrent hole 28 In the plate 26 is a transcurrent hole 28, which should have a size smaller than the size of the clip frame 12 on which the decorative frame 10 will be installed. The reason for this is that the clips 18 must not be visible. Naturally, the hole 28 can have essentially any form at all, for instance a circle, heart, etc., on condition that the clip frame 12 is able to cover it without any of the clips 18 being visible.
  • a recess in the form of a shoulder 32 Arranged on the rear side 30 of the decorative frame 10, around the transcurrent hole 28, is a recess in the form of a shoulder 32, into which the clip frame 12, with the front side facing downwards, must be pressed at the time of assembly.
  • the depth of the shoulder 32 is preferably at least the same as the thickness of the clip frame 12. The depth may be greater, however.
  • the shoulder 32 should also, regardless of the form of the transcurrent hole 28, be essentially rectangular and positioned outside the edge 34 of the transcurrent hole. In order for the necessary gripping engagement to be provided when the clip frame 12 is pressed down into contact with the shoulder 32, the shoulder 32 is produced with length and width dimensions which essentially agree with the clip frame 12.
  • the width and length dimensions of the shoulder are equal to or slightly smaller than those of the clip frame.
  • the length dimension for example, can be made the same as the length dimension of the corresponding clip frame 12, and the width dimension can be made slightly larger than the width dimension of the clip frame 12. The reverse is naturally also possible, so that the length dimension is made slightly larger and the width dimension is made the same as the corresponding dimensions of the clip frame 12.
  • the edge 36 which stands up between the front side 38 of the frame 10 and the recess 32 next to the transcurrent hole 28 can vary in thickness.
  • the edge 36 can be made essentially as thin as required.
  • the edge 36 can naturally also be made very thick.
  • a second embodiment of the invention which is shown in Figs. 3a and 3b, is a frame 10 which has a cross section intended to make contact with only the outer edges 20 of the picture holder 20, i.e. a frame 10 with at least the same thickness as a clip frame 12, but which does not have a recessed shoulder 32 around the transcurrent hole 28.
  • the clip frame 12 is instead pushed down by an appropriate amount into the transcurrent hole 28, so that the clips 18 are visible from the front and so that the inner edges 34 of the frame interact with the outer edges 20 of the picture holder.
  • the hole is the same as or slightly smaller than the clip frame, or for the length dimension, for example, to be the same as the length dimension of the corresponding clip frame 12 and for the width dimension to be rather larger than the width dimension of the clip frame 12.
  • the reverse is naturally also possible here, too, so that the length dimension is slightly larger and the width dimension is the same as the corresponding dimensions of the clip frame 12.
  • the thickness of the frame 10 and the distance from the front side 38 or the rear side 30 at which the clip frame 12 is placed in the hole 28, it is possible to obtain more or less depth in the framing, i.e. the border from the glass sheet 16 of the clip frame up to the front side 38 of the decorative frame 10 can be made larger or smaller.
  • a third embodiment is shown, which can have very low weight and in which the frame 10 in cross section consists of an open profile 40 with a U-like shape, in which the leg which forms the inner edge 34 of the frame is arranged with a curved form 42, which curved form 42 is formed so as to overlap the picture holder 12.
  • the curved form 42 permits the clip frame 12 to be retained resiliently in the same way as in the other embodiments.
  • Fig. 5 shows an example of a fourth embodiment of the invention, in which the frame 10 consists of a thin shell 44, which forms the front side 38 and lateral surfaces of the frame. Since this construction has a thin cross section, the rear side 30 of the frame can be reinforced with advantage with the help of, for example, ribs or other types of reinforcing elements 46, which are moulded directly with the shell 44.
  • the hole 28 in the frame can be one of the previously described types of hole.
  • Fig. 6 shows an example of a fifth embodiment.
  • This embodiment is basically a frame 10 in accordance with one or other of the previously described first and second embodiments.
  • the edge 34 of the hole i.e. the surface that is in contact with the clip frame 12
  • securing elements 48 in the form of, for example, ridges (as shown in Fig. 6) and/or local raised points in an appropriate pattern.
  • the task of these securing elements 48 is to ensure that the frame 10 possesses sufficient flexibility to allow it to retain the clip frame 12 resiliently. This is particularly suitable when the materials used are not so flexible.
  • the securing elements 48 By designing the securing elements 48 with a small material thickness, these are more flexible than the rest of the frame 10 and can help to secure the clip frame 12 by ensuring more reliable contact between the frame 10 and the clip frame 12.
  • a further sixth illustrative embodiment of the invention comprises a frame in accordance with the above introduction, which exhibits a cross section enabling it, too, to make contact with only the outer edges of the picture holder.
  • This illustrative embodiment is not shown in a separate drawing, however, but exhibits characteristic features which, in large parts, correspond to the frames shown in the drawings. More specifically, however, the frame consists of polyurethane or some other similar material which exhibits similar material characteristics.
  • This embodiment is also of such a nature that the frame is so arranged, thanks to the characteristics of the frame, as to clamp the picture holder securely in an all-round groove formed in the material of the frame by pressing in the picture holder after flexing the frame into a form resembling that of a curved banana, viewed in cross section.
  • an existing groove will have been formed internally in the centrally located accommodating opening of the frame, i.e. an all-round accommodating groove will have been made by the harder all- round peripheral edge of the picture holder in the softer frame material, and in which aforementioned accommodating grooves the picture carrier is subsequently accommodated with the frame suspended thereon.
  • the entire frame is again flexed as indicated above, whereupon the picture holder can be removed from the frame.
  • An already used frame can naturally be reused simply by flexing the frame when it is wished to introduce the picture holder into its existing formed accommodating grooves along the internal edge of the all-round opening in the centre of the frame.
  • An important consideration is simply that mutually opposing sides of the four sides should exhibit smaller dimensions than the dimensions of the picture holder on the corresponding sides.
  • inventions of the invention can be manufactured with a highly varied appearance, among other things depending on what material is selected, and as far as the material used in manufacture is concerned, it is desirable for it to exhibit low density and to be inexpensive and easy to process.
  • the requirement for strength in the material is relatively small, on the other hand, primarily because hanging does not take place from the decorative frame, but from the clip frame.
  • the material it is nevertheless desirable for the material to be resilient, i.e. flexible, as well as deformable to a certain degree, if it is to be easy to assemble and disassemble the decorative frame.
  • the material should also be dimensionally stable, so that its form is not changed by the inner stresses that arise in conjunction with assembly.
  • the frame should preferably be manufactured in a material selected from the group consisting of polyurethane, polyurethane elastomers, polystyrene, acrylonitrile butadiene styrene and polycarbonate.
  • the frame may be manufactured from copolymers of these such as polystyrene mixed with acrylonitrile butadiene styrene. It is also possible to consider manufacturing the frame in polyethylene mixed with ethylene vinyl acetate.
  • foamed polymer materials for example polystyrene and polyolefin. These polymer materials exhibit adequate flexibility, and the fact that they are capable of being foamed allows a very low density to be achieved. Thermally expanding polymers can also be used to advantage, which, by being heated slightly, facilitate assembly of the frame on the clip frame. These are subsequently allowed to cool, and this gives a satisfactory gripping engagement.
  • fibre materials i.e. materials based on different types of fibres such as natural fibre, synthetic fibre, glass fibre, carbon fibre and mineral fibre/rock wool, which are mixed with bonding agents.
  • the material can be given a very low density and its rigidity will be dependent, on the one hand, on the rigidity of the fibre and, on the other hand, on how many contact points exist between the fibres that have been bonded together.
  • a decorative surface layer on the outside of frames for example in the form of different surface structures.
  • This can be achieved, for example, by applying different types of covering, for example textile or paper.
  • Another method, which is applicable to the use of polymer materials, for example, is for the surface structure to be formed already at the manufacturing stage, for example by laying structural elements in the walls of the mould.
  • the frames can also be varnished or painted with different colours, of course, and they can also be coated with a paint containing structural fillers in the form of, for example, sawdust or plastic balls, which impart both colour and a surface structure.
  • cardboard or corrugated board can be used, which is easy to process for example by punching.
  • Cardboard and corrugated board are sufficiently resilient to enable gripping engagement to be applied, and they can be manufactured in different colours and thicknesses.
  • Textile or paper can be used to obtain different surface structures, such as the existing undulating surface of the corrugated board.
  • the manufacturing process for the frame in accordance with the invention is naturally highly dependent on what material is selected.
  • polymer materials are used, there is a choice of various manufacturing techniques, including injection moulding, compression moulding, blow moulding or vacuum moulding, in which moulds are used.
  • the frames can then be manufactured in a single piece and, as already mentioned, they can already be imparted with a surface structure at the moulding stage by providing the inside of the mould with the desired pattern.
  • Another alternative manufacturing method is extrusion, in which the frame is extruded in parts by means of the extrusion process. In this case the polymer mass is forced through a profile die exhibiting the cross section of a part of the frame, see Figs, lb and 3b, whereupon the parts are joined together by the use of fixing means such as adhesive or screws, etc.
  • the starting material should preferably be in the form of finished sheets, from which the frames can be punched, for example in one or more punching operations.
  • a frame of this kind can be formed directly in a mould.
  • a decorative frame in accordance with the invention can be manufactured in strong cardboard or corrugated board.
  • the frame 10 can then be punched out directly from sheet material in the form of, for example, a sheet or a roll.
  • the material can be in a single layer, so that the thickness of the frame corresponds to the thickness of the cardboard or the corrugated board. It is also conceivable for the cardboard or the corrugated board to be glued in layers.
  • the hole 28, in which the clip frame 12 will be fitted, can be formed in a variety of ways. For example, the hole 28 can be punched out with or without an inner shoulder surface 32.
  • the hole 28 is made of a similar size to a corresponding clip frame 12, so that the decorative frame 10 can be passed precisely over the outer edge 20 of the clip frame and more or less retained there by the tight fit. The clips 18 are then visible on the front side 38.
  • punching is instead performed with a tool provided with a shoulder 32, in accordance with the first embodiment, the transcurrent hole 28 inside the shoulder 32 is made smaller than the clip frame 12, and the larger hole including the shoulder 32 is made in a size corresponding to the clip frame 12. In this way, the clip frame 12, with the glass sheet 16 in front, can be forced against the shoulder 32 so that its clips 18 are not visible from the front side 38 of the framing.
  • the cardboard or corrugated board frame can be given another surface structure after punching, for example by covering it with textile or paper which, for example, is folded and glued in place.
  • the invention is not restricted to the illustrative embodiments referred to here, but a number of variations are conceivable within the scope of the accompanying Patent Claims.
  • the cross sections illustrated in Figs, lb and 3b can be produced so that the front side/outward- facing side of the frame exhibit an arched surface, or a graduated/segmented surface, and one cross section of the frame can be square, rectangular or triangular.
