The invention concerns a picture frame comprising a viewing window side and a frame side, with the viewing window side comprising a transparent window and with there being an interstice between the transparent window and the frame side for placing a flat object, i.e. a photo or picture, which can be visibly positioned to either side, and with the viewing window and frame sides comprising assembly components for mounting the viewing window and frame sides onto each other and thereby enclosing the flat object.
The invention also concerns a picture frame system comprising at least two picture frames forming an arrangement of picture frames which can be connected together by means of connecting elements.
The invention also concerns a connecting element for connecting picture frames together.
Frames comprising a viewing window side and a frame side which can be mounted onto each other, with a picture being visible through the transparent window, are known from the prior art.
There can be further parts between the viewing window side and the frame side or between the viewing window section and the frame section. The parts together, including the viewing window section and the frame section, form a picture frame for presenting a photo or picture. Such photo frames comprise an interstice between the viewing window side and the frame side for placing a flat object, i.e. a photo or picture.
Examples are known from the U.S. Pat. Nos. 4,608,770, 5,544,436, 5,544,438, the US patent application 2007051063, the US patent application US201116758, the US patent application US2002066218, the Japanese patent application JP2002066218, the Chinese patent application CN105832068 and other documents.
Known picture frames require a relatively large portion of the viewing surface to be used to enable assembly and this assembly is often achieved using separate components. The assembly components in known picture frames are positioned in or on the frame sections such that the assembly space required for the assembly components forms an edge around the photo or picture to be presented or the picture needs to be perforated. Due to this edge which is present outside the surface of the picture to be presented, most picture frames thus formed are intended for presenting stand-alone pictures. Some of these picture frames can be connected together to enable multiple pictures to be presented in a collage structure, but in all these cases they are intended for independent pictures. Cutting one picture into several parts and placing them in different frames in order to display the overall picture would cause excessive interruptions in the overall picture because of the space required for the assembly components.
If a total picture or photo is to be displayed divided over two or more picture frames in order for them to jointly display one complete picture or photo, the interstice necessary for the assembly components will distort the appearance of the composite total picture or photo since the assembly edge is in the visible surface. The partial pictures are placed apart, separated by assembly edges, as a result of which a composition of several parts of a picture spread over several adjacent frames cannot be shown without any disturbance. There will be an interruption in the appearance of the picture to be displayed at or near the transition from a picture frame to an adjacent picture frame due to the distance from one part of the photo to the next part of the photo being too great.
An objective of the present invention is to provide a picture frame and a picture frame system such that, on a visible side of the picture frame, partial pictures which are part of a total picture are connected properly from one outer edge to the outer edge on the opposite side so that one image can be displayed, spread over multiple adjacent picture frames with minimal interruptions in the transition of the picture from one frame to the next.
For this purpose, the photo frame according to the invention is characterised in that the assembly component on the frame side comprises a flexible protruding clamping part, provided with a clamping part on a side facing the viewing window and the viewing window provided with a complementary clamping part at an edge of the viewing window with the complementary clamping parts fitting into each other and with, when assembled, the protruding clamping part on the frame side exerting a clamping force on the viewing window with the direction of the clamping force being mainly in the plane of the viewing window. The clamping force may comprise a slight (up to 25% of the total force) downward, i.e. transversally to the window, component. There are protruding clamping parts on at least two opposite edges of the picture frame.
The invention enables the width of the edge to be reduced, allowing pictures to optically match together better.
The clamping parts preferably do not, or not substantially protrude beyond the outer surface of the window. This minimises the optical effect of the clamping parts.
The clamping parts of the window are preferably provided with notches at the edge which constitute less than 20% of the length of the edge if the material used for the frame side is rigid or they are all around if the frame side material is particularly flexible.
As a result, the optical effect of the clamping parts is relatively small.
The viewing window and frame sides are also referred to here as “viewing window section” or “frame section”. For the purpose of the invention, “picture frame” is also considered to mean a frame for presenting a flat object which has a picture on it, such as an etching, drawing, water colour, screen printed image, lithograph, embroidery, page from a book, etcetera.
The present invention provides a design on the viewing window side in which the picture to be presented can extend almost to the edge and in which the assembly components extend in this edge from the frame section to the viewing window section such that, for example and preferably, an edge of only 1 to 2 millimetres wide is required. The viewing window section can extend above this edge and defines the outermost dimensions of both sections with a photo enclosed. Outside this edge where the viewing window section extends above the frame section and the window and frame sections connect together, the edge of the viewing window preferably has a rounding or chamfer to the outer edge shaped such that, when looked at from the viewing side, a lens or optical enlarging effect is created on the window, with the outer edge with the enclosed photo or picture's image information being optically stretched and thus partially or entirely projecting over the edge between the two sides of two viewing window sections. The rounding which enables this optical effect preferably has a beam whose focal point is below the outer edge of the photo and thus has the superimposed image information within the projection beam. If two adjacent frames have both been laid against each other with their viewing window sides facing the viewing plane and each contains a connecting partial photo or partial picture, this part of the invention will cause the pictures to optically connect more closely to each other and the actual edges of material where the frame parts between the viewing window and frame sides join will be less visible. If, according to embodiments of the present invention, the photos or pictures were to present one total picture together, optical reduction of the interstice between adjacent viewing windows will improve the perception of the picture and will contribute to the perception of the two parts of a total image as a single entity again. The optical effect intended by the rounding or chamfering towards the edge of the viewing window section is interrupted where the connection causes the clamping parts of the frame section to engage in the side of the viewing window section, which is a preferred embodiment of the present invention comprising a solid non-transparent element equal to the material of the entire frame side. This optical interruption is slight since the clamping parts do not protrude above the viewing window.
Because the eye sees an interrupted total image that consists of several parts combined together as a single entity if the image information itself is not optically interrupted, the intermediate edges of the frames used according to the invention are minimised to ensure that only a limited part of the image information is lost at these edges which are connected together as a result of the assembly. Using the lens effect in the edge is not required since an outer edge of 1 to 3 mm for each individual picture frame is a very limited interruption. However, the lens effect creates further optical improvement.
Even without the lens effect resulting from a convexity or slope near the edge, it is a part of an embodiment of the present invention that the surfaces in the edges where the viewing window section connects to the frame part are sloping resulting in reflective surfaces and, as a result of this slope and the reflection, image reflections occur in the inner side of the viewing window section which colour the interrupted edge with image information from the picture or photo.
This means that the use of a slope or, preferably the convexity, according to the invention has the optical effect that the picture to be displayed is optically stretched at the edges and this also applies to the reflection effect of sloping surfaces in the transparent window under the edge. The clamping parts, hereinafter called ‘hook parts’, and the notches and the fact that the clamping parts preferably do not protrude above the viewing window surface, together with the optical effect or reflection effect and the slope or convexity cause the image to be displayed to extend to the edge, or almost to the edge, and the assembly components to be hardly, if at all, visible in the total picture. This improves the possibility of achieving an optically smooth transition between picture frames.
The picture frame system according to the present invention thus provides the option of displaying pictures with a viewing side in the frames by simply displaying the frame sides of the viewing window and frame sections assembled together, possibly in a setup where these frames are connected together or are mounted to the wall without being connected together.
Furthermore, it is an objective of the present invention in preferred embodiments to present the picture on the viewing window side whereby a contiguous whole can be displayed and whereby the picture frames can be connected together by means of connecting elements which are also enclosed by the assembly component which is used to assemble the viewing window and frame sides together and where the connections with adjacent frames can be achieved by means of these assembly components.
In the prior art there are picture frames provided with suspension elements in order to mount the frames to the wall. In many cases, these suspension elements prevent the picture frames from being able to be used on the front and the rear sides and thus make them suitable for mounting on one side only. It is a further objective of the present invention to keep the weights of the frame parts low by using narrow materials and by the absence of any loose assembly components so that they can be easily attached to a wall using tape, possibly double-sided tape.
Known picture frames often provide an eyelet or other mechanism for wall-mounting on the rear of the picture frame. As a result, the picture frame can only be used on one side. An eyelet which enables the picture frame to be moved freely to adjust its horizontal position is often used. This free movement is also the reason why many of these frames with a wall-mounting mechanism hang crooked after some time.
The use of tapes prevents these frames from changing orientation after having been installed. Besides the frames' front and the back being able to be freely determined, the frames according to the present invention do not have a specific bottom, top or side either.
According to the present invention, if several photo frames connected to each other are to be attached to a wall which is not perfectly flat, e.g. a brick wall, the connections should be flexible in order to enable and compensate for the out-of-flat position of the frames.
Many of the picture frame systems known from the prior art which can be connected together have a connecting element to connect several picture frames together in a frame, but this is by means of a connection using rigid connecting elements of non-flexible material and the movement between them is controlled by a mechanical hinging effect of picture frames connected together. This prior art includes, without limitation, U.S. Pat. Nos. 5,544,438, 5,544,436, 6,230,428, WO2015/089320, FR2963222 and JP201141778.
The present invention provides for a picture frame system comprising at least two picture frames and a flat connecting element for interconnecting the—at least—two picture frames, with the connecting element comprising one or more central openings for receiving a clamping part of the picture frames which are to be connected, and, when assembled, the parts of the connecting element located on either side of the one or more central openings are clamped into the—at least—two picture frames.
This is an easy way to achieve a connection which offers many opportunities.
The connecting element is preferably made of a thin ductile flexible material which enables an assembly of picture frames in a frame to be easily placed against, and attached to, a wall which is not flat. The thin, preferably, plastic material is flexible due to its limited thickness and enables frames which can be connected together to bend away from the flat plane in order to compensate for any unevenness of the wall.
Due to the use of a ductile material for the connecting element, the orientation of this ductility in the connecting elements is not limited to bending along one axis or in one direction. The connecting elements for connecting picture frame parts of different frames together are preferably punched from a stiff yet ductile material of slight thickness. The connecting elements according to the present invention are enclosed as well if a viewing window section is complementarily secured between the bulges of a frame section and thus they can preferably move freely between the two assembly components. This enables an assembly of several frames to easily be stuck to walls that are not flat.
If one wants to provide for interconnectable frames for using standard photo sizes with variable placement position orientations and, as is the case in the present invention, they should be able to be presented up to their edges behind a complete viewing window, the standard photo sizes also determine the dimensions of the frames. If each of them comprises a minimum edge of only 1 to 3 mm and frames of different sizes are to be connected together, the present invention provides for the use of a connecting element whereby the interstice between adjacent frames can be varied.
In an embodiment of the present invention, the variation in the interstice can be achieved by using differently shaped connecting elements, each of which is appropriate for achieving a certain distance between the frames.
In another embodiment according to the present invention, the connecting element itself preferably has two or more orientations in which it can be used and which enables the interstice to be determined. In a preferred embodiment of the invention, the connecting element has holes which complementarily match coupling elements. The position of the coupling element in the attachment to the frame section can be adjusted so that the attachment distances of frame sections can be varied for different frame sizes and orientations.
For example, the attachment of the coupling element on a short side of a rectangular frame can be located further inward, reducing the distance between two frames coupled together along this short side. In a frame made up of, for example, two frames for photos of 15×15 cm and three frames for photos of 10×15 cm, the present invention provides that the necessary edges around the photos which enlarge the frame dimensions and thus create an uneven distance between the two frames and the three frames are compensated and are evened out by changing the interstice for the different dimensions as well as the edge thickness of the frame parts. The two rows of frames are thus given equal total dimensions so that the coupling elements in two frames which are to be coupled are at corresponding distances. The picture frame connection system according to the invention therefore provides for system elements which enable several different sizes to be connected together into a collage.
In the prior art it is often prescribed that the parts are made of plastic but a definition is lacking as to why plastic is necessary and there is no description of the properties which the plastic to be used should satisfy in order to make the invention feasible. Thus, in most cases, the properties of the plastic are not part of the invention except for the fact that they determine the choice of material. There are plastics with very rigid properties as well as plastics with very flexible properties and they can be produced in different ways, for example by injection moulding, extrusion or calendering. The present invention preferably provides for injection moulding using a very rigid yet clear plastic for the viewing window sections and a plastic that is somewhat more flexible for the frame sections so that the ductility of connecting elements can be achieved, and the specific limitation of this choice of plastic can be overcome. The shapes of the frame parts in the present invention are so specific that they must be manufactured by injection moulding and, in addition, according to the present invention, the viewing window section is made from a very transparent, yet consequently rigid and hard plastic. Transparency as a property of the plastic causes this plastic to be very rigid and inflexible. The hardness and rigidity are direct consequences of clear injection moulded plastic which cures into a hard material. A soft-curing injection moulded plastic with the envisaged surrounding wall thickness of 1 to 3 mm cannot or can hardly be produced as a completely clear plastic because the soft properties are achieved by plasticizers which will cloud the material. Therefore, the clear transparent window section is hard and has little flexibility in the present invention, but its clarity enables an undisturbed view of the picture presented. To assemble a viewing window section with a frame section, the frame section is preferably made of a softer plastic that is not clear and is therefore more flexible. The viewing window section can be enclosed or assembled within the bulges on the frame section because the perimeter dimensions stretch flexibly within the bulges of assembly elements on the frame section, thus offering just enough space to provide for the introduction and assembly of the viewing window section between the bulges in the frame section.
In many instances of the prior art, parts are provided which are intended to assemble the two sides of a frame together. Not only do these assembly options take up space in the viewing plane of the picture, but they also come with separate elements which complicate assembly. Nuts and bolts are provided in many cases. The present invention does not require any separate elements to mount the two frame sides onto each other, but the clamping of the viewing window section between the upright fixed hook elements on the frame section provides for assembly without additional separate parts.
An important detail in a preferred embodiment of the present invention is that the viewing window section is clamped to the frame section on a contact surface in the side of the viewing window section instead of in the viewing plane on the viewing window section and therefore requires minimal space in the viewing plane on the viewing window side and thus does not disturb, interrupt or perforate the picture to be enclosed. The present invention provides for assembling rectangular and square frames but the system can also be applied to hexagonal. octagonal or round frames.
Many coupling systems or connecting elements which enable frames to be coupled or connected together are known which are characterised in that they have clearly visible adjustments to their shape which enable coupling. In many cases where these frames are hung individually, the openings and mounting elements are clearly visible and the frames are not actually intended to be hung individually. Part of the present invention is to provide a connection method for adjacent frames whereby the connections between frames are made using transparent materials comprising flat parts preferably of a thickness of less than 0.5 mm, preferably located at the centres of the frames where the separation between the viewing window section and the frame section is located and the connecting element is enclosed. This attachment is provided in the centre, enabling frames to be connected together on two sides, with alternating viewing window or frame sides, without there being any differences in height in the flat frame created by several connected frames in a collage. If a frame according to the invention is individually mounted to a wall in a free space, the opening between the parts where the connecting elements would engage in the case of connected assembly is so minor and is incorporated in the joint between the frame and viewing window sections such that it does not show in such a way that it might give the impression that the frame was not intended to be hanging on its own.
The connecting elements according to the invention are preferably made of a dense, non-porous material and preferably transparent so that the visibility of any connections between frames which are visible from the viewing side is reduced because people can see through the connecting elements to the wall behind the frame.
If the interstice between the attachment of a connecting element on one frame and the attachment in the adjacent frame to be connected were increased, it is a part according to the invention that the ductility of the material of the connecting element would enable the frames to adjoin at an angle. According to the invention, this enables three or more adjoining frames to be turned into a three-dimensional assembly of frames.
Many standard sizes exist for photographic prints. It is a part of the invention to provide a frame system for those standard sizes enabling different standard sizes of photos to be connected together in different assemblies in complementary frame sizes. Commonly used photo sizes are 10×15 cm, with actual sizes of 101.6 mm by 152.4 mm, and 15×15 cm with actual sizes of 152.4 mm by 152.4 mm which is due to the fact that these sizes originated from American inch sizes such as 4 inch×6 inch and 6 inch×6 inch. It is a part of the invention that the dimensions of the frames are provided such that, when connected, for instance three photos of a height of for instance 10 cm in their respective frame housings and assembled together come to the same total height as two photos of for instance a height of 15 cm in corresponding frames and such that the coupling elements when in position in each frame are all equidistant from the corner of the frame and, in a collage of several contiguous frames, opposite coupling elements are adjacent to each other. In view of the exact sizes of the photographs which already have an identical overall height independently of the three (10×15 cm) and two (15×15 cm) frames in this assembly, the present invention provides for minimal frame edges around those photos which are narrower on the longitudinal sides of the frames intended for 10×15 cm than the edges in the frames intended for 15×15 cm photos so that the interconnected frames in the assembly also achieve the same overall size. The connection system of the present invention causes the interstice between the two 15×15 cm frames to be greater than the interstice between two longitudinally adjacent 10×15 cm frames and causes the combined distances of different wall thicknesses and interstices where the rows of the two configurations can be connected together to be such that the positions of these connecting elements are accurately adjacent. This enables different sizes of frames to be combined together in a collage.
In an embodiment of the present invention, the frame connecting elements are punched from transparent and dimensionally stable hard yet ductile sheet material. Simple punching devices can only punch a hard material of minor thickness because too much force is required to cut through thicker material. Cutting lines in the punch enable holes in the part which have to be placed over the joint to go past the bulge which needs to be passed since the connection surfaces around the hole can bend along with the notch made and thus a temporary enlargement of the hole can let the bulge pass through. The notches also enable edges of the connector to be secured behind bulges in the glass or the frame part at the location of the enclosed connector.
Existing systems require much space in the viewing plane outside the dimensions of the picture to assemble the front and back together. In the prior art, in many cases, the assembly elements and the connection mechanism technology are located centrally between the frame parts and therefore require a lot of space in the visible surface. An objective of the invention is to assemble the viewing window and frame sides such that the space required along the outside of the picture to be placed on the viewing window side is minimised. A one to three-millimetre edge is sufficient to assemble both sections using the method according to the invention. Altogether, this minimum space is insufficient to use assembly techniques such as nuts and bolts or similar techniques according to the method in the prior art. The assembly according to the invention is possible within this small space by clamping the viewing window section between assembly elements of the frame part extending directly next to the picture with minimal use of material. The assembly is achieved by flexibility in the material of the frame section enclosing the viewing window section which is to be placed within overlying protrusions.
In an embodiment according to the invention, the connecting elements have been punched simultaneously as a grid of several connecting elements or they have been injection-moulded but not detached yet. The connecting elements thus remain attached to each other and maintained in the same flat plane and users can detach the desired parts themselves.
In an embodiment according to the invention, the frame section and the viewing window section are provided with different complementary connection surfaces which align with complementary notches at the correct positions in the outer wall when assembling the frame parts so that the viewing window section is enclosed in the correct location in the frame section. A self-locating action of the two frame parts is created by placing connection surfaces at a complementary angle along which the frame parts slide towards one another in order to achieve the correct assembly position and are positioned opposite each other thus that the upper edge of assembly elements with a bulge rests against the lower edge of the notch in the viewing window and slight manual force creates sufficient movement in the assembly element so that both edges pass one another and the bulge reaches its complementary closed position corresponding to the notch.
In an embodiment according to the invention, the complementary corners of connection surfaces are also intended to guide the photo to be enclosed into the desired correct position within the frame section before it is assembled together with the viewing window section.
When enclosing a photo and/or a passepartout between the two frame sections after assembly, these sections should preferably be provided with edges on both the frame section and the viewing window section with self-locating complementary edge parts at an angle so that these oblique planes help to correctly position the two frame parts and so that the point of engagement of the bulge on the assembly element is correctly positioned on the edge of the receiving notch in the viewing window section when, by the temporary bending of the mounting elements, these are placed in complementary position next to each other and the viewing window section with the complementary notch is enclosed between these assembly elements on the frame section. It is more specifically the ductility of the frame section material and the rigidity of the viewing window material that create a kind of click connection between notches in the viewing window section and assembly elements at complementary locations in the frame section.
The connection surface of walls in the edge of the viewing window section is preferably at an angle so that the colour of the material of the frame section is reflected in it and outwards when looking at the viewing window section.
In an embodiment according to the invention, a passepartout is printed on hard yet ductile film so that this film also functions as a viewing window and can optionally be included as part of the appearance of the picture to be placed in it; this passepartout is printed on both sides in the colour or with a motif of the desired passepartout. The dimensions of the passepartout material correspond to the interstice between the frame and viewing window sections, so that it will be enclosed such that it fits the picture when these frame parts are assembled.
In an embodiment according to the invention, the passepartout is a flexible transparent layer with a colour or motif print on two sides and the passepartout can optionally be placed, with one side visible, over the illustration on both the viewing window and frame sides. The gap between the frame parts offers just enough room to mount both the picture and the passepartout in between, thus providing the picture with a colour or motif border or another design.
These and further aspects of the invention are described below and illustrated by means of the drawing:
The figures contained in the drawing show the following:
Not all figures are drawn to scale; as a rule, like numerals denote like elements.
The parts of the picture frame and the picture frame assembly shown in the figures have been provided with the following numerals:
The picture frames comprise a viewing window side 1 provided with a viewing window 3, a frame side 2 and assembly components 5 in order to assemble the viewing window and frame sides together. A photo or picture 4, visible through the viewing window 3, is provided for between the viewing window side 1 and the frame side 2. Note that the fact that one of the sides is referred to as the “viewing window side” does not exclude that the opposite side, the ‘frame side’ is also transparent. In that case, both sides are both the viewing window side and the frame side.

The further
The complementary clamping sections 52 and 31 of respectively clamping part 51 and viewing window 3 fit together. The viewing window preferably comprises three notches in its edge into which the clamping parts 31 fit. These notches extend along only a part of the edge according to an embodiment according to the invention, preferably less than 10% of the length of the edge although it is also possible to provide the entire edge of the viewing window with complementary clamping section 31 and to close the viewing window section all around as a consequence of flexibility with the complementary clamping section.
Notch 53 forms an entrance between the frame parts on both sides of the protruding clamping part 51 which is moulded inwardly around protruding clamping part 51 and provides a flat insertion space 56 which extends on both sides around clamping part 51 through edge section 54, preferably with a raised part 55, as indicated in this example.
Due to the connection system of the present invention, the width of the gap between two picture frames for 15×15 cm photos is greater than the width of the gap of two longitudinally adjacent 10×15 cm picture frames. If a collage is assembled with a column of two 15×15 cm picture frames on the left or right and a row of three 10×15 cm picture frames on the right or left, where the edges of picture frames should be aligned at the top and bottom, the gap width between the 15×15 cm picture frames will be virtually equal to twice the width of the gap between the 10×15 picture frames, i.e. for example 0.5 mm and 0.25 mm. In this example, this makes the dimension U for the 10×15 cm picture frames 0.125 mm greater than the dimension U for the 15×15 cm picture frames. The differences in W and thus U cause the combined distances of different wall thickness and interstices to be such that the positions of these connecting elements are accurately adjacent where the rows of the two configurations can be connected together. This enables frames of different sizes to be combined into a collage, assuming fixed existing photo sizes.
Furthermore, the distance X should preferably be slightly less than 1 inch (2.54 cm).
As explained above, the actual standard sizes that apply to photos, even if expressed as centimetres, are based on inch sizes, i.e. 15×15 cm is 6×6 inch.
In the collage described above, two 15×15 cm picture frames on the left and three 10×15 cm picture frames on the right, the left and right-hand rows under the upper edge and above the lower edge of the collage can be interconnected using connecting elements if X is identical for all picture frames. The left-hand and right-hand rows are then interconnected in two places. A suitable choice of X enables more interconnections of left and right-hand rows to be made.
There are four possible attachment points for connecting elements on the left, measured from the top edge downwards:
There are six attachment points on the right at positions
By ensuring that twice the width of the gap on the right equals the width of the gap on the left, attachment points 1 and 4 on the left will be aligned to attachment points 1 and 6 on the right so that the left-hand and right-hand rows of the collage can be interconnected.
Attachment points 2 and 3 on the left are aligned with, attachment points 3 and 4 on the right respectively, if the following equations are satisfied:
15 cm−X=10+gap width on the right+X and
15 cm+gap width on the left+X=20+gap width on the right−X
That gives two equations and they can be simplified by subtracting the lower equation from the upper equation to form
Gap width on the left−2X=−10+2X
10−gap width on the left=4X
X=2.5−0.25×gap width on the left.
As stated above, the actual sizes are inch sizes, i.e.
X=1 inch−0.25×gap width on the left. With a gap width on the left of e.g. 0.5 mm, the answer is then 1 inch−0.0125 cm=2.53 cm. To compensate for some tolerance in manufacturing accuracy, X is preferably between 2.45 and 2.55 cm.
The advantage for the embodiment listed is that the left and right-hand rows can be interconnected by connecting elements at four points instead of only two points.
The two connected picture frames can be two relatively small picture frames, in which case there is a relatively narrow gap with width 2W1 between the two picture frames, with W1 being the W value for a relatively small picture frame. The same universal connecting element 6 can also be used to connect two relatively large picture frames, each with a W value of W3. In that case, the gap width between the two relatively large picture frames is 2W3. In order to compensate for these differences and for any minor variations in size, the openings in the connecting element 6 have been constructed such that some tolerance has been provided. This is indicated by T in
It will be clear that the invention enables many variations and that the invention is not limited to the examples described above.
In summary, the invention can be described as follows:
A picture frame comprises a viewing window side (1) and a frame side (2) with the viewing window side comprising a transparent window (3). There is an interstice between the viewing window and the frame side. A photo or picture can be placed here. The viewing window and frame sides comprise assembly components (5) in order to assemble the viewing window and frame sides together. An assembly component on the frame side comprises a flexible protruding clamping part (51), provided with a clamping section (52) on a side facing the viewing window (3) and the viewing window (3) is provided with a complementary clamping section (31) at an edge of the viewing window (3) with the complementary clamping sections (52, 31) fitting into each other and, when assembled, with the protruding clamping parts (51) exerting a clamping force (F2) on the viewing window (3) with the direction of the clamping force (F2) being mainly in the flat plane of the viewing window.
