Description

FOLDABLE FRAME FOR HOLDING AN IMAGETECHNICAL FIELD The present invention relates to a frame for holding an image, suitable for decorative or marketingpurposes. The frame is foldable to enable efficient storage and handling.

BACKGROUND Frames for decorative or marketing purposes are commonly used in a variety of different fields, suchas interior decorating, marketing at fairs and the like, and displays for advertising. Generally, a frameis made from four frame portions that are joined by four corner portions to form a completed frame.The mounting and dismounting often requires tools such as wrenches or screw drivers.

There are some frames on the market that are foldable to allow easier storage and mounting. Thefolding is sometimes achieved byjoints along the frame portions and sometimes by a hinge orpivoting function at some of the corner portions, but it has previously been difficult to make a framethat is stable, does not require tools and does not pose the risk of collapsing if subjected to a forcesuch as a nearby person inadvertently touching or pushing the frame.

On frames of this kind, a picture is applied to display information, an image or a marketing oradvertising message. The picture is sometimes printed on a canvas having an outer edge with asilicon strip attached to allow the edge to be inserted into a slot along the edges of the frame. For afoldable frame, this presents the problem that the image is distorted during folding and storagethrough stretching of the canvas in the folded position or during the folding procedure, making itdifficult or impossible to mount the frame again with the picture still attached and achieving thesame look and feel as before the frame was folded.

There is a need for improvements within this area, especially regarding the folding, handling andstability of the frame.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate or at least to minimize the problems mentionedabove. This is achieved through a foldable frame and a frame system according to the appendedindependent claims.

Thus, according to the invention there is provided a foldable frame for holding an image, the framecomprising four elongated frame portions, each having a first end and a second end, and furthercomprising four corner portions, two of which being of a first corner type and the other two being ofa second corner type, wherein each frame portion is attached to a corner portion of the first type atthe first end and a corner portion of the second type at the second end, so that a frame is formedwhere the corner portions of the first type are diagonally opposite, and wherein the corner portionsof the first type are pivotable about a first axis and the corner portions of the second type arepivotable about a second axis and a third axis, respectively, the second axis and third axis beingparallel to each other and essentially perpendicular to the first axis. Due to the use of two types ofcorners that are configured to pivot about different axes that are perpendicular to each other, the frame can be folded to a small and compact packet that can be placed inside a storage bag and betransported and handled without risking damage. This facilitates transport as well as storage.

According to an aspect of the invention, the first axis extends diagonally across the frame andthrough the corner portions of the first type and wherein the second axis and third axis areessentially perpendicular to a plane formed by the frame. Thereby, the pivoting of the first cornerportions enables a folding into a symmetrical L-shape from which the pivoting of the second cornerportions can be performed.

According to another aspect of the invention, the second axis and the third axis are arranged toessentially coincide after the corners of the first type have been pivoted so that the corners of thesecond type are adjacent to each other. This further facilitates the pivoting of the corners of thesecond type and also decreases the size of the folded frame.

According to yet another aspect of the invention, the foldable frame is of a quadratic or a circularshape. Thereby, the folding of the frame is symmetrical and can be performed without su bjecting thepivots at the corner portions to forces that might damage the pivots.

According to a further aspect of the invention, the frame further comprises a slot for holding edgesof a flexible material with a picture, said slot extending along each of the elongated frame portionsand preferably also extending along at least one of the corner portions. Thereby, a picture on aflexible material can be mounted on the frame and can be fastened on the frame in a stable andsecure manner. Preferably, the slot extends along each of the corner portions to allow the flexiblematerial to be fastened along the entire circumference of the frame. Preferably, there are two slotsfor holding edges of a flexible material with a picture, one of which extends along a first side of theframe and the other extending along a second side of the frame. Thereby, one picture can be held ona first side of the frame and another picture on the second side of the frame, allowing for displays ofpictures in two directions which is especially beneficial in arrangements where the frame is standingon a floor.

According to another aspect of the invention, at least the corner portions of the first type, preferablyalso the corner portions of the second type comprise at least one opening for receiving a locking pin.Thereby, a locking pin can be inserted into the corner portions and prevent folding of the framewhile the pin is in place. This increases the stability of the frame and decreases the risk of accidentsor other situations where the frame is folded inadvertently and its folding movement could causedamage to persons or objects in the vicinity, or to the frame itself and the picture mounted thereon.

According to a further aspect of the invention, the corner portions of the second type comprise anouter primary pivot and two secondary pivots, the secondary pivots being arranged at a first end anda second end of the corner portion, respectively, and the outer primary pivot being arranged at acorner between the first and second ends. Thereby, a pivoting of the corner portions of the secondtype can be performed by pivoting three different joints, allowing for a stable and secure folding thatavoids extending the slot in the corner portion in such a way that the flexible material holding thepicture is stretched and possibly distorted. ln another embodiment of the invention, the corner portions of the second type instead comprise aninner primary pivot and two secondary pivots, the secondary pivots being arranged at a first end and a second end of the corner portion, respectively, and the inner pivot being movably arrangedbetween them inside a corner, and wherein the corner is an open corner. This is an alternativemanner of folding that is stable and secure and allows the corner to open and create a gap instead ofincreasing a length of the slot and causing a stretching of the flexible material that can be mounted inthe slot. ln this embodiment, the inner pivot provides the main stability and the outer secondarypivots help keep an increase in length of the slot to a minimum. ln another embodiment, the corner portions of the second type comprise an inner primary pivot,arranged between a first end and a second end of the corner portion and on an inner side of acorner, and wherein the corner is an open corner. ln this embodiment, only the inner pivot isprovided to give stability to the corner portion. By providing the open corner, the length increase ofthe slot is still kept small and the manufacture of the corner portion is made easier and more costeffective while still providing the main functions of the present invention. ln yet another, preferred embodiment the corner portions of the second type comprise an outerprimary pivot and two secondary pivots, the secondary pivots being arranged at a first end and asecond end of the corner portion, respectively, and the outer primary pivot being arranged at acorner between the first and second ends, and further comprising an inner primary pivot, arrangedbetween the secondary pivots on an inner side of the corner. This embodiment provides the stableinner pivot as well as a stable outer pivot and two secondary pivots and is the most stable version ofthe corner, also providing a minimal extension of the length of the slot holding the flexible material. ln all these embodiments of the corner of the second type, it is preferable that each pivot is arrangedto pivot about an axis that is parallel to or coincides with the second axis or the third axis. Thereby,the folding of the frame is improved and additional forces on the pivots can be avoided to preventdamage to the pivots. lt is to be noted that parallel in this regard is to be understood as essentiallyparallel within the normal manufacturing tolerances.

According to another aspect of the invention, the invention further comprises a flexible material witha picture, the flexible material having edges that are insertable into the slot to mount the picture onthe frame, wherein the edges are lined with a holding material, preferably silicon, for securelyholding the flexible material in the slot. Thereby a picture can be mounted in a secure and stableway, providing the ability to stretch the flexible material across the frame and present the picture ina smooth and adequate manner.

According to yet another aspect of the invention, the invention further comprises at least one lightsource mounted on at least one of the frame portions. Thereby, the inside of the frame can beilluminated so that a lighting is provided to a back side of the flexible material with the picture,resulting in an illuminated picture being shown in the frame.

According to the invention, there is also provided a frame system comprising at least one of thefoldable frames according to the invention and further comprising at least one locking pin mountedthrough an opening in at least one of the corner portions for blocking a folding of the foldable frame.Thereby, the frame can be fixed in a mounted state without requiring additional fastening means.

According to an aspect of the frame system according to the invention, the assembly comprises aplurality of frames according to the invention, the plurality of frames being connected to each other by locking pins to form a frame assembly. Thereby a larger frame assembly can be made byconnecting the frames to each other by means of the locking pins, providing a desired size and shapeof the frame system in order to present pictures or images of a desired shape and size.

According to another aspect of the invention, the frame system further comprises at least one footportion, said foot portion having at least one cavity for receiving a foot locking pin so that a framecan be mounted on the foot portion via the locking pin. Thereby, the frame assembly can stand on itsown without additional support, thereby enabling use as a dividing wall or a standing display in aconvenient and efficient manner. The foot locking pin can in some embodiments be identical to thelocking pin.

According to a further aspect of the invention, the foot portion comprises at least two cavities so thattwo frames can be mounted side by side via locking pins. Thereby, a desired number of frames canbe connected side by side to create a frame assembly of the desired size while also providing stabilityto each other so that no further support is needed. The frames can also be mounted at an angle withrespect to each other, preferably 45 or 90 degrees.

According to yet another aspect of the invention, the frame system further comprises a flexiblematerial with a picture, the flexible material being arranged to form a picture surface on the frameassembly and having edges that are insertable into slots forming an outer circumference of theframes of the frame assembly. Thereby, pictures can be mounted on each separate frame or onelarger picture can be mounted on a plurality of frames put together, to further add versatility to theframe assembly and allowing a user to design a shape, size and distribution of images across theframe assembly.

According to a further aspect of the invention, the frame system further comprises a flexible materialwith a picture, the flexible material being arranged to form a picture surface on the frame assemblyand having a first side and a second side, said first and second side being joined together along atleast one edge, and at least one of said first side and second side having dimensions that essentiallymatch dimensions of one side of the frame assembly. Thereby, a single picture can be mounted overthe frame, eliminating the need for the slot.

Many additional benefits and advantages of the invention will become readily apparent to theperson skilled in the art in view of the detailed description below.

Each frame portion 21, 22, 23, 24 have a first end21a, 22a, 23a, 24a that is connected to a corner portion of a first type 33, 34 and a second end 21b,22b, 23b, 24b that is connected to a corner portion of a second type 31, 32 so that corner portions ofthe first type 33, 34 are diagonally opposite to each other in the frame 1. A slot 5 is provided in anedge of the frame portions 21, 22, 23, 24 and preferably also in the corner portions 31, 32, 33, 34 sothat the edge 5 runs along the entire frame 1. Also seen in Fig. 1 are locking pins 4 that are insertedinto openings 35 to prevent the corner portions from folding (see Fig. 8). Also shown in Fig. 1 are footportions 41 that are mounted on foot locking pins in two of the corners 32, 33, to enable the frame 1to stand without further support. ln this preferred embodiment, the foot locking pins are threadedand secured to the foot portions 41 by screwing into a corresponding inner thread in an opening inthe foot portions 41. Also, the foot locking pins are shorter than the locking pins 4, but it is to benoted that the foot locking pins could also be identical to the locking pins 4 and that they could bemounted in the foot portions 41 by clamping, snap connections or simply by being received intocavities or receiving openings on the foot portions 41.

The corner portions of the first type 33, 34 are pivotable around a first axis A that preferably extendsdiagonally across the frame 1, and the corner portions of the second type 31, 32 are pivotablearound a second axis B and third axis C, respectively, as shown in Fig. 2. The second and third axes B, C preferably coincide or at least are essentially parallel after a first folding step, as will be describedin detail below.

The folding of the frame 1 from a mounted state to a folded state is performed through a first foldingstep (see Fig. 1-3) wherein the corner portions of the first type 33, 34 are pivoted and a secondfolding step (see Fig. 3-5) wherein the corner portions of the second type 31, 32 are pivoted.

Before the first folding step, any locking pins 4 inserted into the corner portions must be removed.The corner portions of the first type 33, 34 are then able to pivot around the first axis A so that thecorner portions of the second type 31, 32 are brought into contact with each other as disclosed byFig. 3. This concludes the first folding step.

The second folding step is performed by pivoting the corner portions of the second type 31, 32around the second and third axis B, C. Before the first folding step, the second and third axis B, C areessentially parallel but afterwards they preferably coincide or at least remain essentially parallel asshown in Fig. 3. The second folding step brings the corner portions of the first type 33, 34 intocontact with each other to arrive at the folded state shown in Fig. 5.

The folded state is stable and robust and allows for the frame to be handled, stored and transportedwithout causing damage to the corner portions 31, 32, 33, 34. lf a piece of flexible material 6 with apicture or image is mounted on the frame the folding can be performed without having to removethe flexible material 6, provided that the flexible material is mounted on a first side 71 so that thecorner portions of the first type 33, 34 are pivoted in a direction towards the first side 71. ln thefolded state, the flexible material 6 can be maintained in the slot 5 around the circumference of theframe 1 without risking distortion or damage to the flexible material 6 and the image or picturethereon. This is especially due to the corner portions of the second type 31, 32 being configured topivot with a minimum elongation of the slot 5 along the corner portions 31, 32, as is shown in Fig. 6a-6c.

Thus, Fig. 6a shows one of the corner portions of the second type 32 in more detail. The presentinvention encompasses various embodiments of this type of corner portion, of which a preferredembodiment will be described now. This preferred embodiment has outer portions 35, 36 that meetat an outer primary pivot 32a and inner portions 37, 38 that meet at an inner primary pivot 32c. Theouter portions 35, 36 are joined to the inner portions 37, 38 by secondary pivots 32b, 32d,respectively. ln Fig. 6b, the corner portion 32 is half way between a mounted state in Fig. 6a and a folded state inFig. 6c. All of the pivots 32a, 32b, 32c, 32d cooperate to allow the corner portion 32 to fold and ateach of the outer primary pivot 32a and secondary pivots 32b, 32d a small gap ö is opened. The slot 5is elongated slightly by the pivoting of the corner portion 32 and in the folded state of Fig. 6c it canbe seen that the slot 5 is slightly longer than in Fig. 6a since the slot 5 is elongated at each of theouter primary pivot 32a and the secondary pivots 32b, 32d but that this elongation is considerablysmaller than would be case without the presence of the secondary pivots 32b, 32d. The innerprimary pivot 32c mainly serves to increase stability of the corner portion 32. ln this preferredembodiment, distortion of the flexible material during folding and in the folded state can be kept to aminimum and essentially avoided altogether, giving the advantage or being able to store the frame 1for long periods of time with the flexible material 6 still attached. ln an alternative embodiment, the inner primary pivot 32c may be excluded to leave only the outerprimary pivot 32a and the secondary pivots 32b, 32d. This embodiment is less robust than thepreferred embodiment but still allows for a minimal extension or elongation of the slot 5 to preventdistortion of the flexible material. ln another alternative embodiment, the outer primary pivot 32a can be excluded and the connectionbetween the outer portions 35, 36 eliminated. ln this embodiment, the inner primary pivot 32cserves to provide stability and the secondary pivots 32b, 32d allow for avoiding stretching the flexiblematerial 6 during a first part of the second folding step. ln the folded state of Fig. 6c, thisembodiment would have an opening where the outer portions 35, 36 meet. ln another alternative embodiment, only the inner primary pivot 32c is provided. |nstead of thesecondary pivots 32b, 32d the outer portions 35, 36 are joined to the inner portions 37, 38 at theirends where the secondary pivots should have been and they are not connected where the outerprimary pivot 32a would have been, instead forming an open corner. lt is to be noted that the outer primary pivot 32a and the inner primary pivot 32c are both movingwith respect to the secondary pivots during the second folding step. ln Fig. 7, a frame system 100 with four foldable frames 1 according to the invention is shown, theframes 1 being mounted on locking pins 4 to form a frame assembly 10. At least a middle one of thefoot portions 41 is able to receive two locking pins 4 from adjacent frames 1 so that two frames 1 canbe mounted side by side on the foot portion 41. ln Fig. 7, one of the frames 1 is being mounted bylowering in a vertical direction onto locking pins 4 and locking pins can also be inserted horizontallyto fixate two frames in relation to each other. The frames 1 in Fig. 7 are mounted in a straight line,but in another embodiment the foot portions 41 are angled so that the two frames 1 mounted onthe same foot portion 41 are held at an angle to each other, preferably at 45 degrees or 90 degreesbut other angles could also be suitable. The foot portions 41 would then have two cavities orreceiving openings for receiving foot locking pins and these receiving openings are arranged at adistance from each other and positioned in such a way that a frame 1 mounted on a foot locking pinin one of the cavities or receiving openings and a frame 1 mounted on a foot locking pin in the otherof the receiving openings are held at an angle with respect to each other.

Fig. 8 discloses the locking pin 4 when inserted into two frames 1, 1' to mount one frame on top ofthe other. The frames 1, 1' have essentially the same features so that the lower frame 1' comprisestwo frame portions 21', 24' and a corner portion of the first type 34' whereas the upper frame 1 hasa corner portion of the second type 32 meeting the corner of the lower frame 1'. Both types ofcorner portions 32, 34' and indeed all corner portions disclosed for the frame and frame system ofthe present invention may be provided with at least one but preferably two openings 35 throughwhich a locking pin 4 can be inserted. ln Fig. 8, the locking pin 4 extends from a position inside thelower frame 1' to a position inside the upper frame 1 to establish a secure connection between themand to prevent any of the corners from pivoting to fold the frame.

Fig. 9 discloses a frame 1 with a piece of flexible material 6 mounted along a slot 5, and in Fig. 10 themounting of flexible material on both a first side 71 and a second side 72 of the frame 1. Thus, on thefirst side 71 the flexible material 6 is mounted in the slot 5 by insertion of an edge 61 of the flexiblematerial 6. The edge 61 also has a strip of a holding material 62 that serves to hold the edge 61 securely in the slot 5. The holding material 62 is preferably silicon but can alternatively be any othermaterial that is suitable for this purpose, such as rubber or another polymer material. On the secondside 72 of the frame 1, a second piece of flexible material 6' is mounted by insertion of a second edge61' into a second slot 5'. The second edge 61' is also provided with a strip of holding material 62' in asimilar way to first edge 61.

Fig. 11 discloses a frame system 10 with four frames 1 mounted together. Each of the frames has apiece of flexible material 6a, 6b, 6c, 6d mounted thereon in slots 5 extending along an edge of theframes 1. The flexible material may form four different pictures or be parts of the same pictures. ln Fig. 12, the frame system 10 is shown with a larger piece of flexible material 6 that is mounted onall four frames 1 by insertion of edges of the flexible material 6 into slots on the frames 1 asdescribed above.

Fig. 13 discloses a piece of flexible material 60 that forms a pouch with a first side 60a on which apicture is formed and a second side 60b that may also have a picture but can be without picture. Thefirst and second sides 60a, 60b are joined together along at least one edge but preferably along threeedges and they are mounted by inserting the frame assembly 10 into the pouch formed by theflexible material 60 in a manner that is similar to the insertion of a pillow into a pillow-case. Thus, thefirst side 60a and second side 60b have dimensions that match the dimensions of the frame assembly10 so that the pouch fits around the frame assembly 10 and present the pictures or images in adesired way.

A light source is preferably also mounted on at least one of the frame portions 21, 22, 23, 24 toprovide illumination to an inside of the frame and to the flexible material 6 so that the picture isilluminated. ln some embodiments it is sufficient to provide a light source on only one of two of theframe portions 21, 22, 23, 24, but in embodiments where the frame 1 is very large it would be betterto provide light sources on more or all of the frame portions 21, 22, 23, 24. The light sources can beany kind of light source suitable for mounting in this way, such as for instance high powered LEDdiodes.

Light sources can also be provided as flexible LED strips or the like on the flexible material 6 or on aseparate sheet of flexible material mounted on the second side 60b in order to illuminate a pictureon the first side 60a. Alternatively, an addition sheet can be provided inside the frame to illuminatepictures on both the first side 60a and the second side 60b. ln some embodiments, light from lightsources provided on the frame portions 21, 22, 23, 24 can be spread by providing a sheet ofperforated plexi glass or similar inside the frame so that a more even light distribution is achieved. lt is to be noted that a mounting of the frame from the folded state to the mounted state can beperformed by reversing the first and second folding steps that are described above, to arrive at theframe 1 in the folded state of Fig. 1. lt is also to be noted that features from the various embodiments described herein may freely becombined, unless it is explicitly stated that such a combination would be unsuitable.
