Definitions

• the invention relates to a picture frame consisting of a blank according to the preamble of claim 1.
• Known picture frame with an image printed on its central part, in which the cardboard edge lying outside the image area is formed as a frame folding part e. (DE-PS 586 029).
• the frame folding parts each consist of a number of folding sections lying in parallel, which are delimited by five fold lines or scoring lines.
• the middle part of the cardboard blank enclosed by the innermost scoring line contains an image to be framed, which can be printed, painted on or glued on.
• the frame edges are created by bending the folding sections lying between the individual scoring lines.
• the edges of the frame are joined together at their corners. This type of connection, however, regardless of how the connection of the corners is designed, results in only a relatively low strength of the picture frame.
• the middle part of the frame containing the picture should only have the normal size of a postcard for which the strength of the frame edges is sufficient.
• picture frames for larger picture formats cannot easily be produced with the desired strength properties if a relatively thin cut is used for reasons of material and cost savings.
• the frame edges can be fixed in detail according to the prior art in that the folding sections surrounding the middle field are each equipped with two protruding tongues which are inserted into the middle field after inserting a card into the middle field in the course of folding the folding parts into incisions.
• Disadvantageous is that the insertion of the tongues has to take place in the course of folding over the frame folding parts, as a result of which the production of the picture frame can be too complicated for end users.
• the non-smooth surface of the back of the picture frame, from which the flat-fitting tongues protrude, may be visually disturbing, although the protruding tongues can also be equipped with eyelets for hanging the picture frame.
• the prior art also includes a picture frame made from a sheet of paper or cardboard, from which a rectangular opening is punched out, so that a frame edge is created.
• a picture frame made from a sheet of paper or cardboard, from which a rectangular opening is punched out, so that a frame edge is created.
• four side flaps or tongues and eight side flaps are punched out of the sheet.
• the side flaps are inserted into pockets created by folding, which result from wrapping around the side flaps or tongues (DE-PS 305 389).
• This production of the picture frame can also be too cumbersome and result in insufficient strength properties for picture frames, which are suitable for large formats.
• the present invention has for its object to form a picture frame consisting of a blank of the type mentioned in such a way that the completion of the picture frame from the blank, i.e. the folding and clamping of the frame edges is simplified, so that such picture frames can be produced by inexperienced people with great chances of success.
• the picture frame thus obtained is said to be extremely strong and also suitable for large-format pictures (posters). This object is achieved by the formation of the picture frame consisting of the blank with the features specified in the characterizing part of claim 1.
• this picture frame can also be produced from the blank by an inexperienced person, in that the processes of forming the hollow frame edges and the subsequent fixing of the frame edges can be carried out separately one after the other.
• the frame edges can simply be set in such a way that the tabs, which lie on top of one another after the frame edges have been formed, are pushed into the frame edges, being folded around their connecting webs.
• the overlapping tabs fix the frame edges reliably, since they not only grip the corners of the picture frame, but also over the circumference of the frame edges.
• the picture frame is therefore characterized by great rigidity even when the blank is made of relatively thin, inexpensive material that can be easily processed. Paper, cardboard or plastics are suitable as the material for cutting.
• the tabs provided according to the invention are characterized in that they do not protrude from the cut in the extension of the frame folding parts, but are completely enclosed by the surrounding material of the frame folding parts. After forming the hollow frame edges and fixing them by pushing in the protruding tabs, these practically completely disappear into the hollow frame edges. They therefore do not interfere even if the back of the picture frame is fully or partially visible, for example if it is largely placed freely in the room.
• the tabs of the first and second rows are preferably pre-punched as partial circles. This shape ensures good detachment of the tab from the surrounding edge of the hole.
• the connecting webs by means of which the tabs are integrally connected to the surrounding frame folding parts, should have a smaller width than the diameter of the part circles which define the tabs or the conforming hole edges. If two such tabs lying one above the other on the frame edges are bent approximately at right angles into the frame wheels, an upper one of the two tabs engages behind the lower of the two hole edges, so that a clamping effect occurs, ie that folding sections of the folded-over frame folding parts or the frame edges no longer exist can be solved in this area, as long as the tabs are folded over and reach behind the hole edges.
• the above-mentioned pitch circle shapes represent the circle segments according to claim 2.
• the design of the connecting webs with the tab with different widths according to claim 3 ensures that the tab located further out in the preformed frame edge can fit closely to the lower tab when both tabs are folded over, and that both tabs lying one above the other in this bent position can be held reliably.
• a third tab of a further row of tabs, the preferred arrangement of which is specified in claim 4, can preferably be used to lock the two bent tabs in this position.
• These tabs of the third row of tabs are tongue-shaped, that is to say preferably longer than the tabs of the first and second row of tabs, so that the tongue-shaped tabs of the bent tabs of the first and second rows lying one above the other in this position can hold that the tongue-shaped tabs are also bent, but at a smaller angle so that the end faces of the tongue-shaped tabs can be supported in the vicinity of the end faces of the bent tabs of the first and second rows.
• the tabs in the third row are therefore relatively long. Nevertheless, they do not disturb the pleasing visual impression, since they also largely disappear into the hollow frame edge and do not protrude beyond the frame edge.
• three rows of tabs are arranged on the center panel and fold sections, into which fold sections each frame folding part is subdivided.
• the fold sections are limited by grooved fold lines.
• the outermost fold section lies between one of the fold lines and an outer edge of the blank.
• This cut is suitable for forming the picture frame according to claim 6 with a frame edge which is rectangular in cross section, in which the fold section adjacent to the middle field is folded back over the fold line about its fold line adjoining the middle field, the remaining fold sections of the frame fold part connected to this fold section are also folded back, and then the individual further folding sections are folded in the opposite direction by 90 ° to the frame edge.
• the outermost folding section is led behind the midfield. From this back, the tabs can then be pushed into the preformed frame edge and bent over.
• This design of the picture frame or the cut for its production is characterized in that all the surfaces visible from the front of the picture frame, ie both the area of the center field as well as the outer surfaces of the frame edge lie on one side of the blank.
• an image in the middle and a frame color can be printed on the frame folding parts on the blank, on one side of this blank.
• the one-sided printable material of the blank is less expensive than two-sided printable material. Since the frame is printed at the same time as the image print on the same side of the blank, the additional effort for printing the frame is minimal. The advantages of picture frame training, which produce a printing of the frame with color matching on the framed picture, are thus increased.
• a simpler embodiment of the picture frame and the blank that can be used for its production is specified in claims 7 and 8.
• This embodiment is simpler insofar as it only provides two rows of tabs which can be bent one above the other in the manner indicated in the interior of the frame edges preformed from the blank, but without being additionally locked in this by third tabs. If the coloring of the frame edges and the image are to be printed on the blank of the second embodiment of the picture frame, then the blank must be printed on both sides, since the back of the blank with the folded sections is bent over the center area to the square frame edge so that the back of the Cut now forms the frame edge visible from the front.
• this picture frame is even easier than that of a picture frame of the first embodiment, since in the second embodiment the folding sections of the frame folding part can only be folded in one direction to the middle field, so no reversal of direction has to be taken into account.
• individual folding sections of the frame folding parts are chamfered on the sides in such a way that the bent frame edges meet at miter corners.
• the picture frame can thus be shaped so that it can hardly be distinguished from a picture frame with a solid frame edge.
• the innermost fold lines which thus lie between the middle field and the innermost fold section of the frame edges, are preferably perforated. On these perforated fold lines, the frame edge can be separated from the center panel on request. It is thus possible for different frames and images produced in this way to be combined with one another.
• the flaps formed on the frame edges of a picture frame and their perforated edges are to be folded together with the flaps of the middle field of another picture frame in the same way in the same way as in the case of a one-piece design of the middle field with the foldable frame folding parts.
• detachable corner sections on the blank not only specifies the edges of the frame folding parts for forming the frame edges that meet without gaps, but additional protection is achieved at the corners of the blank before the final picture frame to be made by the end user in the last one Manufacturing stage is converted.
• the detachable corner sections can be used for other purposes, for example, they can be provided with holes so that the cuts can be hung on sales stands.
• the detachable corner sections for the first variant of the picture frame are shaped so that the hollow frame in the folded state edges, the mitred edges of which can be joined together by means of an adhesive strip, which can be glued through the opening from the back of the picture frame over these edges and other frame edge parts. This ensures a particularly appealing appearance of the frame edges in the manner of a solid frame if a corresponding imprint was made on the frame folding parts.
• the rows of holes of the frame edges can additionally be used to connect a plurality of picture frames in a picture frame arrangement by means of flat, rectangular-shaped strips which can be bent about a center line.
• the tabs pre-punched in the strip are additionally folded over into the holes delimited by conforming hole edges in the picture frame, after such a strip has been placed over two parallel frame edges of two adjoining picture frames from the rear.
• picture frames can be put together on all of their sides and connected in pairs with a strip. Since the strips can be bent around their center line, larger spatial shapes can also be created by bending the interconnected picture frames, for example cuboids, prismatic bodies or folding walls.
• two picture frames which are connected on one side by the strip, can be set up in the manner of a roof, whereby the connecting strip lies in the ridge line.
• the picture frames and strips in the picture frame arrangement are suitable for the production of largely freely selectable shapes for shopfitting or exhibition stand construction.
• the connecting webs of the tabs in the strips are preferably alternately close or distant to the center line over its length.
• This and the arrangement of the connecting webs offset by 90 ° with respect to the connecting webs in the picture frame means that the connections between the strips and the picture frame can be loaded to a high degree in opposite directions, particularly in tension.
• the length of the strips can be adapted to the dimensions of the frame edges which are intended to connect the strips to one another.

• the tongue shape of the tabs 28 and the circular segment shape of the tabs 26 and 27 can be found in detail in FIG. 2. All tabs are connected to the cut via connecting webs 29-31, which are drawn in an interrupted manner. The edges of the blank which delimit the flaps are not provided with reference numerals in the drawing.
• the connecting webs of the first and the second row of tabs preferably have different widths, specifically the connecting webs of the first row of tabs 26 are wider than those of the second row of tabs 27.
• the width of the connecting webs 26 is in 3a with Bl and the width of the connecting webs of the tabs 27 in Fig. 3b with B2.
• a picture frame is first formed from a blank 1 according to FIG. 4 in such a way that the frame folding part 3 is folded back in its entirety about the fold line 21 over the front of the middle field 2. Then the folding sections 16-20 are each bent back by 90 ° around the adjacent fold line. The direction of bending is indicated by the arrows not shown in FIG. 4. The bending takes place in such a way that the frame edge, as viewed in the direction of the cross-sectional side, assumes the shape shown in FIG. 5. From this it can be seen in particular that the outermost folding section 20 is bent back under the middle field 2 and that the remaining frame edge with the sections 17-19 lies on the front of the picture frame. The tabs 26, 27 and 28 of the three are in this position Row of flaps one above the other.
• FIGS. 7 and 8 which represents the end position of the tabs.
• the tabs 26 and 27 are bent due to the different width of their webs lying close to each other by about 90 ° in the interior of the frame edge and in this position by the downwardly pressed and projecting over the end faces of the tabs tongue-shaped tab 28 in be held in this position, since the tabs 26 and 27 press against the end face of the tab 28.
• the frame edge formed from the frame folding part 3 is securely locked in the configuration shown in FIG. 5.
• a piercing opening 32 is provided directly through the hole edge of the tabs, here adjoining the tab 26, through which a tool can be inserted , with which the tabs 26-28 - see FIG. 6 - can be bent back into the position according to FIG. 5, so that the frame edge can be folded flat again.
• the frame edges 33-36 are mitred on the front and back of the picture frame, for which purpose the folding sections 16 and 18 in FIG. 2 are chamfered.
• the side cutouts or the perforation on the side of the folding section 20 results from the fact that when the corner section 7 is cut off, a large, here triangular opening 37 is to be formed on the back of the picture frame, through which an adhesive strip 38 from the back over the abutting edges of the edges can be glued to allow them to be connected to one another practically without gaps.
• a second variant of the cutting of the picture frame which is shown in FIGS. 11-20, consists of a cutting, which is generally designated by 39.
• the blank again has a central field 40, of which a smaller image field 41 can be used, and frame folding parts 42-45 surrounding the central field.
• the frame folding parts meet at corner sections 46-49, the edges of which are in turn perforated for pulling out the corner sections.
• Every frame folding part, e.g. 42 - see Fig. 12 - is again subdivided into five fold sections 50-54, which are defined by grooved fold lines 55-59c Only one fold section is chamfered to the side here, e.g. Folding section 51 of the frame folding part 42 so that the hollow frame edges 60-63 folded from the frame folding parts abut on one another, see FIG. Fig. 20.
• This is due to a different way of folding the frame folding part compared to the first variant, as will be discussed below.
• the shape of the corner sections or their edges is determined by the fact that here a rectangular opening 64, see FIG.
• the adhesive strip holding the abutting edges of the frame edges in FIG. 15, which can be inserted through the opening 64 after completion of the frame edges from the rear, is designated by 65.
• the folding sections of the frame folding parts are bent here in each case in the same direction by 90 ° relative to one another around the folded edges, so as to give a winding shape of a frame edge with a rectangular cross section according to Fig. 14, which is complete over the edge of midfield 40 lies and is not enough with a folding section on the back of the picture frame.
• the frame edge can cover part of the image field 41, which is indicated in FIG. 14 with a broken line.
• a row of tabs 66 is arranged here in the middle panel 40 near the innermost folding section 50 along the frame folding part.
• a parallel row of tabs 67 is pre-punched from the second outermost folding section 53.
• the tabs 66 and 67 which are shaped as circular segments and are connected to the blank via connecting webs, are in detail according to the tabs
• the connecting webs of the tabs 66 are preferably wider here than those of the tabs 67, in order in turn to ensure a tight fit of the two tabs bent into the interior of a frame edge, cf. Fig. 17. It should be noted that here the tabs 66 of the first row lie further out - seen from the rear, cf. also Fig. 13, which shows a view of the back. The clamping effect of the two tabs 76 and 77, of which the tab 66 is held under the hole edge of the tab 67, which is not designated, corresponds to that of the first variant. However, the angled position of the two tabs 66 and 67 is not secured by a third row of tabs.
• FIGS. 17 and 18 it should also be pointed out that the frame edge shown in detail with these figures is formed from a frame folding part which does not have the outermost folding section 54 according to FIG. 12.
• the corresponding frame folding part can thus be simplified, although the strength of the frame edge 17 and 18 is slightly less than that of the frame edge according to FIG. 14.
• FIG. 15 which shows a view of the picture frame in the area of the frame edge according to FIGS. 16 and 17, seen from the rear, can be seen that here too
• a piercing opening 68 is provided, through which a tool for bending back the angled flaps 66, 67 can be inserted in order to be able to unfold the frame edge flat again if necessary.
• the described picture frames of both variants are not only characterized by good strength properties in themselves, so that they can be carried out in large format, but they can also be put together with simple means to form larger picture frame arrangements which can have a spatial shape .
• Flat rectangular strips which are designated 69 in FIGS. 21-25, are used to assemble the picture frames. Each strip can be folded around a center line 70. Symmetrically to the center line, two rows of tabs 71, 72 are formed parallel to one another, which, like the tab-shaped tabs of the blanks of the picture frames of both variants, are pre-punched. The tabs are arranged so that the connecting webs are alternately close and distant to the center line, see in detail in Fig. 21.
• the connecting webs are rotated by 90 ° with respect to those of the blanks of the picture frames when from a position of the strip 69 the back of at least two picture frames is assumed, as shown in FIG. 23 for four picture frames 71-74.
• a strip 69 covers two adjacent picture frames, for example 71, 72 and 73, 74.
• the strip runs parallel to the frame edges on the back of the pictures frame.
• the tabs 71, 72 of the strips are inserted into the same holes on the back of the picture frames, which holes are left free by the tabs of the picture frames, which are normally provided for fixing the frame edges. All tabs disappear inside the hollow frame edges, so that a visually appealing appearance of the picture frame arrangement is also seen from the rear.
• FIGS. 24 and 25 The position of the tabs in the frame edges is shown in detail in FIGS. 24 and 25, in which, in addition to the frame edge of a picture frame, a strip 69 that can be folded about the center line is shown. Since the tabs 72 of the strip 69 are arranged at right angles to the tabs 26, 27, 28 of the picture frame of the first variant, the functions of the two tab types do not interfere with one another, but complement one another in that the tab 72 can be supported on the tabs 26-28 .
• Fig. 26 shows two angular or roof-shaped picture frames. This basic form is supplemented in FIG. 27 to form a folding wall, which is particularly suitable as a display for exhibition purposes.
• a spatial prismatic shape is shown in Fig. 29, which is hung here on hangers 79-81. 28, on the other hand, shows a box-shaped arrangement of two superimposed cubic basic shapes, which act as a column is set up.
• the simultaneous installation of picture and frame in only one work step results in cost savings even if only individual picture frames that are not connected are used.
• the design of the frame and picture can be conveniently coordinated when printing the blank.
• the picture frames thus offer a cost-effective sales aid by effectively presenting products in the image area or in the middle of the cut.
