    Clamping element for clamping a canvas or cloth and method applied thereby.
    The present invention relates to a clamping element for clamping a cloth, in particular a canvas.
    A canvas is a canvas that is used for painting or printing and can be hung on the wall as a kind of painting.
    Such a cloth is traditionally made from linen or hemp or another material.
    It is known that such a cloth is tensioned on a custom-made frame that is composed of slats that are connected to each other with a miter connection in the corners of the frame.
    After the frame has been provisionally assembled, the cloth to be stretched is placed on the frame and the edges of the cloth on the outer circumference of the frame are folded over the slats and fixed to the back of the frame by means of staples or the like.
    When the cloth is stapled around in this way, the frame is tensioned by means of wedges, so that the cloth is stretched tightly and without folds around the frame.
    A major drawback is that customizing the frame and putting the frame together is relatively complex and time-consuming and requires a certain amount of professional knowledge and skill.
    Another drawback is that applying the cloth to the frame is also not simple, especially with regard to the finishing in the corners where the folded edges of the cloth overlap, for which purpose the cloth in the corners usually has to be cut up to the the relevant corner of the frame and the cut edges of the canvas must be meticulously folded over each other and around the frame and stapled. The finish of such a cloth in the corners is usually not so nice and is clearly visible when the cloth is hung.
    A drawback associated with this is that making the frame and tensioning the canvas are actions that are not reserved for the man with the cap; these operations are usually performed in a specialist shop where they sell ready-made pre-stressed canvases, for example to be painted, or in a specialist shop where they can print such canvases and then stretch them on a frame.
    The present invention has for its object to provide a solution to at least one of the aforementioned and other disadvantages.
    To this end, the method relates to a clamping element that can replace the aforementioned traditional frame and which moreover greatly simplifies the clamping of a cloth and without visible overlaps in the corners of the cloth.
    To this end, the invention relates to a clamping element for clamping a canvas or cloth, the clamping element comprising a frame and a rectangular plate or rectangular frame, the dimensions of which correspond to the dimensions of the frame, the frame being essentially composed of four profiles be provided on one side with a slot in the longitudinal direction of the profiles, and wherein the plate or frame has four peripheral edges with a hinged wing on each peripheral edge, wherein the canvas or cloth to be tensioned can be attached to the wings, the wings be hinged between a mounting position where they protrude sideways to be able to attach the plate or window to the back of a canvas or cloth to be tensioned and a folded clamping position where the wings fold over and around the profiles of the frame placed on the plate or window are possible, with the inclusion of a corner of the canvas or cloth to be stretched, one and others such that the edges of the wings can be fixed in the aforementioned slot.
    In order to tension a canvas or canvas, a clamping element according to the invention is selected whose outer dimensions of the plate or frame with the wings in mounting condition correspond to the outer dimensions of the canvas or canvas to be tensioned and the following steps are carried out: of the canvas or canvas on a flat surface with the back side facing up; - bringing the wings into the mounting position; - placing the window or plate on the canvas or cloth and attaching the canvas or cloth to the wings and possibly also to the window or plate; - placing the frame on the window or plate; - folding the wings into their clamping position, wherein the wings are folded around the profiles of the frame and wherein during corners the corners of the canvas or cloth are pushed inwards to enclose the cloth between the wings; - fixing the edges of the wings in the slot of the frame.
    An advantage is that the tensioning of a canvas or cloth in this way is very simple and requires only a limited number of simple actions. Consequently, it can be applied by anyone without specific training or dexterity.
    The finish in the corners is very easy to achieve. In addition, this finish is sleek and neat and without any folds and overlapping parts visible as the corners are tucked away between the folded wings and are not visible when the canvas or cloth hangs against the wall.
    Another advantage is that, since the canvas or canvas is attached to the wings and these wings are folded over and around the profiles of the frame and thus folded over at least two to three times, the canvas or canvas will, as it were, automatically taut are attracted.
    Moreover, this has the additional advantage that, if the canvas or cloth is not completely tightened during attachment to the wings, this is still largely absorbed during the folding of the wings.
    It is clear that the aforementioned slot in the profiles of the frame can also be understood to mean a slot, incision or recess.
    By "the dimensions of the rectangular plate or the rectangular frame correspond to the dimensions of the frame" is meant that the dimensions of the plate or the frame and the frame are such that the wings of the plate or frame can be folded around the profiles to become.
    The wings are preferably provided with one, two or more grooves, hinges or the like to facilitate or make possible folding of the wings over and around the profiles of the frame.
    By pre-defining the fold or crease line with the help of such grooves, they will be able to be neatly and tightly folded around the profiles of the frame, which will contribute to a professional and perfect finish.
    Of course, it is not excluded that the wings are made of a flexible material so that they can be folded without grooves or the like being provided.
    According to a preferred feature of the invention, the profiles of the frame are partially cut away at the corners of the frame on one side of the frame.
    The advantage is that space is created for the corners of the canvas or canvas that are pushed inwards.
    With the insight to better demonstrate the characteristics of the invention, a few preferred variants of a tensioning element according to the invention for tensioning a cloth or canvas and a method are applied herewith, with reference to the accompanying drawings, in which: figure 1 schematically and in perspective represents a clamping element according to the invention; figures 2 to 11 show successive steps during the method according to the invention for tensioning a canvas or cloth on the tensioning element of figure 1.
    According to the invention, the clamping element 1 as schematically shown in Figure 1 consists of a frame 2 and a rectangular frame 3.
    The frame 2 is a preformed rigid or hard frame 2 that is made up of four profiles 4. The rigid or hard frame 2 is in this case made of plastic, but it is not excluded that the frame 2 is made of wood, thick cardboard or another suitable material that is preferably sturdy and light.
    On one side 5 of the frame, which we will further call the front side 5, these profiles 4 are provided with a slot 6 which extends in the longitudinal direction X-X 'of the profiles 4.
    The four slots 6 extend over the full length A, B of the profiles 4.
    These slots 6 can be provided, for example, by milling.
    In this example, the profiles 4 of the frame 2 are partially cut away at the corners 7 of the frame 2 on one side 5 of the frame 2, the aforementioned front side 5.
    In addition to the four profiles 4, the frame 2 in this case also comprises four corner elements 8 arranged in the frame 2 for reinforcing it.
    The frame is also provided with means 9 for being able to suspend the canvas or cloth, in this case these concern four suspension eyes 9.
    That could also be means 9 for straightening the canvas or canvas, such as, for example, a support as known from a classical photo frame.
    The rectangular window 3 has a central opening 10 and four peripheral edges 11, with a hinged wing 12 on each peripheral edge 11, which in this case, but not necessarily, extend over the full or almost full length C, D of the peripheral edges 11 of the window 3.
    The wings 12 are trapezoidal with corners 14 bevelled at their free edge 13.
    The wings 12 are hinged between a mounting position as shown in figure 1, wherein they extend laterally in line with the plane of the window 3 and a clamping position where they are folded over. This clamping position will be further clarified later.
    The frame 3 and the wings 12 are in this case formed in one piece in cardboard, but they can also be made of, for example, plastic.
    In this case the wings 12 are connected to the peripheral edges 11 of the frame 3 by means of a film hinge 15, which in this case is formed by a V-shaped cut-out 15 in the cardboard.
    It is possible that the film hinge 15 can also be formed in other ways or that the wings 12 are connected in a different way to the peripheral edges 11.
    The wings 12 are in this case provided with two grooves 16 which make it possible to bring the wings 12 into the folded-over clamping position.
    It is possible that these grooves 16 can also be hinges, film hinges or the like, and that only one such groove 16 per wing can be provided or more than two.
    Furthermore, the wings 12 are finished at their ends 17 with chamfers 18 which will abut against each other in the clamping position of adjacent wings 45, which will contribute to neat, perfectly finished corners of the stretched canvas or cloth. This will be explained in more detail later.
    As can be seen from figure 1, the dimensions A, B of the frame 2 correspond to the dimensions C, D of the frame 3. This means that the peripheral edges 11 of the frame 3 have the same dimensions than the length A, B of the profiles 4 of the frame 2.
    The use of such a clamping element 1 as shown in figure 1 is very simple and is illustrated with reference to figures 2 to 11 where use is preferably made of a canvas 19 or cloth whose outer dimensions E, F approximately correspond to the outer dimensions G , H of the window 3 with the wings 12 in their flat mounting condition.
    The canvas 19 or canvas is first directed downwards with the front side 20, this is the printed side or the side intended for painting, drawing, printing or the like, laid down on a table or other flat surface.
    Subsequently, the rectangular window 3 is laid on the canvas 19 or cloth, whereby it is ensured that the wings 12 are in the mounting position.
    Then the canvas becomes 19 or canvas. attached to the wings 12 and possibly also to the window 3.
    In the illustrated example of Figure 3, the canvas 19 or canvas is stapled to the edges 13 of the wings 12.
    After all, the wings 12 are made of cardboard, which will allow the canvas 19 or cloth to be stapled to it.
    That is a very simple operation.
    Alternatively, it is also possible that the window 3 or the wings 12 are at least partially provided with glue or one or more glue strips for attaching the canvas 19 or cloth to the window 3 or the wings 12.
    Such a solution could be used, for example, when the wings 12 are made of a plastic, which makes stapling difficult or impossible.
    It is possible here for the glue or these glue strips to comprise a self-adhesive glue, wherein the glue or glue strips are provided with a peelable cover layer. This cover layer can be peelable in one, two or more pieces.
    The corners 21 of the canvas 19 or cloth are then cut or cut with the aid of a pair of scissors or knife, the beveled corners 14 of the wings 12 being taken as a guide during cutting or cutting, so that this operation is very simple. The canvas 19 or canvas attached to the window with cut-off corners 21 is shown in Figure 4.
    It is important to note that the corners 21 of the canvas 19 or canvas are not further cut or cut.
    The frame 2 is then placed on the frame 3. It is hereby ensured that the front side 5 of the frame 2 is directed upwards, as shown in Figure 5.
    The wings 12 are then folded over into their clamping position.
    The wings 12 are then folded over and around the profiles 4 of the frame 3, as shown in Figure 6.
    Because the wings 12 are provided with two grooves 16 and the film hinge 15, they will facilitate or make it possible to fold the wings 12.
    The grooves 16 and the film hinge 15 will, as it were, pre-define the crease lines, so that tight and neat folds are created during the creasing process.
    The edges 13 of the wings 12 are hereby inserted into the slot 6 of the frame 2 and fixed therein.
    This is shown in Figures 7 and 8.
    The fixation in this case is done by means of clamping blocks 22 which are fixed in the slot 6. Instead of clamping blocks 22 it is also possible to use clips that can be snapped into the slot 6.
    During the folding process, the corners 21 of the canvas 19 or cloth are pushed inwards in order to be able to enclose the canvas 19 or cloth between the wings 12.
    This is shown in figures 9 and 10, in which it can be seen that due to the fact that the profiles 4 of the front frame 5 are partially cut away at the corners 7 of the frame 2, there is room around this corner 21 of be able to enclose the canvas 19 or canvas between the wings 12.
    Moreover, due to the fact that the wings 12 are finished at their ends 17 with chamfers 18 which abut each other when the wings 12 are in their clamping position, a neat, tight and completely closed corner 21 will be created.
    It is clear that in this way the finishing in the corners 21 is very simple and that, in addition, the excess canvas 19 or cloth is neatly concealed inwards in the corners without cutting, cutting or folding.
    In this way all wings 12 are brought to their clamping position, so that the stretched canvas 19 or cloth as shown in figure 11 is obtained. The canvas 19 or canvas is now ready to be used and hung up. Because the window 3 is provided with a central opening, the stretched canvas 19 or cloth in the middle is not supported.
    Although in the examples shown the frame 2 and the frame 3 are two separate objects, it is not excluded that they are or form a whole.
    For example, they can be formed as a whole by injection molding in plastic.
    Alternatively, the frame 2 and the frame 3 can be glued or glued together. For example a cardboard frame 3 and a plastic or cardboard frame 2.
    It is clear that the frame 2 and the frame 3 can also be attached to each other in a different way, for example by stapling.
    Although in the examples shown the wings 12 extend over the entire peripheral edges 11 of the frame 3, it is not excluded that the wings 12 extend over a limited part of the peripheral edges 11, the slots 6 being possibly adapted accordingly to be.
    Although in the examples shown, the clamping element 1 comprises a window 3 with wings 12, it is not excluded that it comprises a plate with wings 12, that is to say that the central opening 10 of the window 3 of figure 1 is missing.
    In this case it is possible or not that the plate is provided on one side, i.e. the one with which it is laid against the canvas or cloth, with a centrally recessed portion.
    In this way a greater rigidity is obtained from the plate and at the same time the canvas 19 or canvas is released in the central recessed portion without support, as with a traditional wooden frame.
    The present invention is by no means limited to the embodiments described as examples and shown in the figures, but a clamping element according to the invention and a method applied therewith can be realized according to different variants without departing from the scope of the invention.
