TECHNICAL FIELD

The subject of the invention is a foidabie stand and a set or unit of a foidabie stand and a cooling device, formed in case of the foidabie stand with at least one shelf of the foidabie stand from foidabie material, such as cardboard, corrugated cardboard, paper and sheets of plastic.

BACKGROUND ART

The availability and the relatively low price of foidabie materials, such as cardboard, corrugated cardboard and paper, are the reason why these materials are more and more often used for manufacturing products facilitating transport, storage and display. The latter include trays, pallets and display devices, particularly stands and their elements.

Given the fact that cardboard is recyclable and suitable for placing inscriptions and pictures, the stands and their elements can be used as information carriers, particularly when advertising and commercial information is placed on them. When the information or advertising becomes outdated, for example after the end of trade fairs or end of sale period of particular products, the cardboard from which the displays are made, particularly stands, can easily be removed and recycled. Therefore, products made of cardboard are environmentally friendly, have a simple construction and are relatively cheap.

Moreover, products made of foidabie materials _, such as cardboard, can be folded, easily carried as folded and assembled again in another place.

The publication DE 3906936 A1 , entitled "Shelf system capable of being assembled from blanks of foidabie material, such as in particular corrugated cardboard, cardboard or the like, which can be folded up to form structural elements of the shelf system" presents a system with shelves which can comprise elements formed from foidabie material, in particular corrugated cardboard. The above- mentioned system comprises vertical supporting columns between which shelves are placed. In order to assure adequate stiffness for the system with shelves, vertical supporting columns are made as internally empty and closed profiles made of sheets whose sides are folded inside the profile.

Similarly, the shelves are empty profiles with cuts on both sides which include the margins of the sheets folded inwards, from which the vertical supporting columns are made.

Then, from the publication AU 1507083 A entitled "Foldable cardboard display stand" a display stand made of foldable paper material is known. It comprises a base, a back panel and side panels, and at least one shelf placed between the panels. The shelf has hinged mounting and it can move from an operative horizontal position to an upright assembled position.

Additionally, the publication EP 1459650 A1 entitled "Shelf made of foldable material such as cardboard" describes a shelf made of foldable material, which may be placed between two vertical stands. The stands have openings in which wings of the shelves are placed, thanks to which the shelves are maintained in a specified position.

The publication WO 201 1078826 A1 entitled "Foldable product display stand" features a foldable, easily-assembled display stand comprised of elements made of paper, corrugated cardboard and plastic, used for displaying various products in shops, supermarkets and workshops.

The publication US 2005279906 A1 entitled "Foldable and self-erecting display stand and easel" describes a foldable and unfoldable display stand which has a large area of carton folded along vertical lines at the back. Between the back panel and side panels there are tensile cords, which are stretched when the display is folded, and which facilitate automatic unfolding of the display stand.

The publication EP 0976348 A1 entitled „Disposable refrigerated display" presents a cooling display containing several shelves on which various products can be placed. The size of the shelves depends on the type of product and its size. Instead of stiff shelves the cooling device can contain nets to hold the displayed products. A cooling element intakes air from inlet holes and cools it to the specified temperature. After that, the cooled air is blown through outlet holes to an inter-wall space formed between internal and external parts of a back panel. The cool air can reach the products placed on the shelves through the holes in the panels. Part of the cool air stream can reach the upper area and can be redirected downwards with the use of a hatch. Thanks to that a cold barrier is formed, which in turn facilitates the protection of the products from the ambient warm air.

The publication EP 1099398 A1 entitled„Display with shelves" describes a display stand with shelves made from a panel-shaped material, characterized by at least two side panels and at least one shelf between the panels. The shelf has at least two parts which can be joined together in such a way that the entire set can be unfolded or folded.

Moreover, the publication DE 200 18 744 U1 entitled „Verkaufsaufsteller" presents a display shelf stand which contains at least two stiff side panels separated from each other. Between the panels there are foldable shelves inserted in the side panels with the use of side elements.

The publication DE 20 2010 01 1 841 U1 entitled„Selbstentfaltendes Tray und regalformiges, selbstentfaltendes Display auf Basis der Trays" presents a foldable shelf stand and a foldable shelf with two side panels equipped with catches and stretching elements for straightening the shelf.

The solutions described above are usually multi-element solutions and are of complicated shapes while their folding and unfolding is time-consuming.

AIM OF THE INVENTION

The aim of this invention is to create a stand with a monolithic and simple construction which would be small after folding to allow transporting it from one place to another. Simultaneously the stand after being placed on a cooling device, ensures intensive cooling of the products placed on foldable shelves.

MODE(S) FOR CARRYING OUT THE INVENTION A foldable stand 100 with a cooling device 5 forming a set or unit 1 of the foldable stand and cooling device, shown in Figs. 1 -7, comprises a left side panel 10, a right side panel 20 and a back side panel having an inner element 30 of the back panel and an outer element 40 of the back panel, which cover at three sides a lower space 2 and a cooling space 3 in which foldable shelves 50 are placed one above the other. The lower space 2, which can contain the cooling device 5, has a front panel 60, which is also called a base or a plinth. The cooling space 3, located above the lower space 2, is closed from the top with a top inner element 70 and a top stiffening element 80 with slots or longitudinal openings 81 and a topper 85 with projections 87, which can be placed in the longitudinal openings 81 of the top stiffening element 80. In the right side panel 20 there are ventilation openings or ports 25, which facilitate the flow of air cooling the cooling device 5 located in the lower space 2.

The lower space 2, in which the cooling device 5 can be placed, and the cooling space 3 with foldable shelves 50, separated from the lower space 2 with a lower internal element 65, are shown in detail in Figs. 2 and 3, which present the foldable stand 100 with a removed right side panel. The lower inner element 65 is shorter than the depth of the foldable stand 100, allowing an inlet opening 4 to be uncovered. The inlet opening 4 is the opening for a circulation stream 6 of cooling air generated by the cooling device 5. The circulation stream 6 of the cooling air after leaving an outlet of the cooling device 5 flows through a rear inter-wall chamber 39, and then flows through a top inner-wall chamber 79, and finally gets into the cooling space 3 from the top. The circulation stream 6 of the cooling air that transports the cooled air to the interior of the foldable stand 100, especially to the cooling space 3, has been shown in Fig. 3 by means of small arrows 95, 96 and 97. The stream of air which cools the cooling device 5 has been shown by means of large arrows 94 and 98. The stream of air which absorbs heat from the cooling device 5, flows inside to the cooling device through the openings or ports 25 in the left side panel 10 and the right side panel 20 of the foldable stand 100 and gets out through the opening in the back, emitting the heat from inside of the foldable stand

100 to the environment.

The advantage of the foldable stand 100 according to the invention is the possibility of ease of transport of the foldable body 1 10 from one place to another together with the foldable shelves 50 which is folded into a flat and cuboid package and which is unfolded in a way shown in Figs. 4 and 5. Before unfolding the foldable body 1 10 of the foldable stand 100, the total thickness of the foldable body 1 10 only slightly exceeds the thickness of the side panels 10, 20 and twice the thickness of the foldable shelf 50. During the unfolding of the foldable body 1 10, as well as during the folding of the body, the bendable shelves 50 are not inserted in or removed from the interior of the foldable body 1 10 but they are attached to the side panels 10 and 20 in a self-aligning manner with catches and/or stabilizing elements, greatly facilitating the folding and the unfolding of the foldable stand 100. During the unfolding of the foldable body 1 10, the left side panel 10 and the right side panel 20 are pulled outwards according to arrows 101 and 102 until the foldable stand 100 is in a stable vertical position. At the second stage of the unfolding, the left side panel 10 and the right side panel 20 are still being pulled outwards according to the arrows

101 and 102, and the back panel with the inner element 30 and the outer element 40 is pushed inwards into the foldable stand 100 (foldable body 1 10) according to an arrow 103 whereas the front panel 60 of the foldable stand, like the left side panel 10 and the right side panel 20, is pulled outwards according to an arrow 106. Under the influence of forces exerted on the panels according to the arrows 101 , 102, 103, 106, the bendable shelves 50 are automatically straighten and after assuming a horizontal position they stiffen the foldable stand 100, which in turn prevents an unexpected folding of the foldable stand 100. The additional elements which stabilize the unfolded foldable stand 100 are edge or tilting elements 69, shown in Fig. 6, which are set in a vertical position according to arrows 105 after unfolding the foldable stand 100. After unfolding, the foldable stand 100 can be placed on the cooling device 5 in a way shown in Fig. 6. The cooling device 5, shown in Fig. 6, whose outer dimensions in the top view are not larger than the inner dimensions of a lower opening of the foldable stand 100, which facilitates putting the foldable stand 100 onto the cooling device 5 from the top. Putting the foldable stand 100 onto the cooling device 5, results in a unit or set 1 of the foldable stand and the cooling device that ensures effective storage and cooling of various types of products, e.g. beverages, whereas outer and inner surfaces of the foldable stand 100 can be used for advertisement and informational purposes.

The top inner element 70, the top stiffening element 80 with the topper 85, which are put onto the body 1 10 from the top, form an upper stiffener of the foldable body 1 10 and close the inner space of the foldable stand 100 at the top. Moreover, between the top inner element 70 and the top stiffening element 80 with an insulating insert 78 there is a top inner-wall chamber 79, shown in Fig. 3, through which a stream of air can flow, cooling the interior of the foldable stand 100 from the top.

The foldable stand 100, whose first embodiment, when disassembled, is shown in Fig. 7, comprises the left side panel 10, the right side panel 20, the inner element 30 of the back panel, the outer element 40 of the back panel, the bendable shelves 50 with at least one joint 56, the front panel 60, which is sometimes called the base, the top inner element 70 with side laths 71 , a guide lath 72 and an outlet 73 and an inlet 74. The top stiffening element 80 with slots or longitudinal openings 81 and the topper 85 which has an advertisement surface 88 with a notch 86 and with the projections 87 which are insertable into the longitudinal openings 81 of the top stiffening element 80 and the insulating insert 78. The left side panel 10, the right side panel 20, the inner element 30 of the back panel, the outer element 40 of the back panel, the foldable shelves 50 and the front panel 60 form the foldable body 1 10 of the stand 100 with foldable shelves 50. The left side panel 10 with a bending line 13 that divides the panel into an outer part 1 1 and an inner part 12 and the right side panel 20 with a bending line 23 which divides the panel into an outer part 21 and an inner part 22, have a cuboid or cubical shape with an inner chamber. While folding the left side panel 10 along the bending line 13, a left side insulating element 19 is placed inside the chamber of the left side panel 10. The element is made of insulating material, e.g. styrofoam or insulating foam. During folding of the right side panel 20 along the bending line 23, there is a right side insulating element 29 made of insulating material, e.g. styrofoam or insulating foam placed inside the chamber of the right side panel 20. After folding the left side panel 10 and the right side panel 20, openings which are formed during the folding process are closed at the top and bottom with insertions 14, 24. Both side panels 10, 20 have on the inner side, adjacent to the foldable shelves 50, openings 17, 27 for catches 51 and in the event that they are present, for stabilizing elements of the foldable shelves 50. The number of openings 17 for the catches 51 of the bendable shelves 50 can be larger than the number of the bendable shelves, and as a result the foldable stand 100 is more universal as the user of the foldable stand can adjust the distances between the bendable shelves 50 depending on the dimensions of the products stored in the foldable stand.

In order to connect the side panels 10, 20 with the inner element 30 and the outer element 40 of the back panel, and the front panel 60, the side panels 10, 20 have slots or longitudinal openings 18, 28 and/or catches 16, 26 in the form of tongues, which are situated in the back area of the side panels 10, 20 and longitudinal openings or slots situated in a front area of the side panels 10, 20. The inner element 30 of the back panel has ports or openings 33 joining the chamber of the back panel with the inner space of the foldable stand 100. Moreover, the inner element 30 has at least one bending line 32 dividing the element into parts 31 , which facilitates the folding of the back panel. The outer element 40 of the back panel has at least one bending line 42 dividing the element into parts 41 , slots or longitudinal openings 43 suitable for inserting the catches 16, 26 of the side panels 10, 20, as well as laps 44 which form the laps for side panels 10, 20, and the ventilation ports or openings or openings for gripping the body and the back opening 45. The outer element 40 is separated from the inner element 30, and in the space between these two elements there is a rear central element 47 with at least one bending line 48. After inserting the rear central element 47 between the outer element 40 and the inner element 30, a chamber is formed between the inner element 30 and the rear central element 47. The chamber facilitates the flow of cooling air. The flow of cooling air into the rear chamber is generated thanks to the fact that the height of the inner element 30 and the rear central element 47 is lower than the height of the outer element 40 and the side panels 10 and 20 of the foldable stand 100. After the foldable body 1 10 is put onto the cooling device 5, the inlet for the flow of cooling air into the rear chamber is above the outlet through which the air flows out of the cooling device. The outer element 40 and the rear central element 47 are joined together with the use of a band or a grip 34, with elements of distance. The band is reeved through openings 37 and has its ends placed in central openings 49 of the rear central element 47.

Similarly, the front panel 60 has projections or protrusions or side catches 61 and at least one bending line 62, which facilitates the folding of the foldable stand 100. Also a bottom inner element 65 has projections or protrusions or side catches 67 and at least one bending line 66, which facilitates the folding of the foldable stand 100. Additionally, in the lower area of the side panels 10, 20 of the foldable stand, ventilation openings 15, 25 are provided, which enable the flow of an air stream that cools the cooling device 5.

During the assembly of the foldable body 1 10 of the stand 100, the side catches 38 situated on one side of the inner element 30 of the back panel, are inserted into the vertical longitudinal slots 18 of the left side panel 10, and the same side catches 38 situated on the other side of the inner element 30 of the back panel are inserted into the vertical longitudinal slots 28 of the right side panel 20. Similarly, the tongue-shaped catches 16 of the left side panel 10 and the tongue-shaped catches 26 of the right side panel 20 are inserted into the vertical, longitudinal openings 43 of the outer element 40 of the back panel, which results in a permanent connection of the left side panel 10 and the right side panel 20 with the inner element 30 and the outer element 40 of the back panel. The next step in the process of putting together the body 1 10 is the assembly of the front panel 60, whose side catches 61 with undercuts on the lower side are inserted into the vertical longitudinal openings situated in the lower front part of the left side panel 10 and the right side panel 20. The height of the front panel 60 is lower than the height of the other panels and as a result the top fragment of the front of the foldable stand 100 is open.

The body 1 10 of the foldable stand 100, shown in Fig. 7, formed from the left side panel 10, the right side panel 20, the inner element 30 of the back panel, the outer element 40 of the back panel and the front panel 60, has a cuboid or cubical shape open at the bottom and the top. Inside the body, above the front panel 60, bendable, foldable shelves 50 are mounted with a bending line or a hinge 56 and the edge or tilting element 69. Each of the foldable shelves 50, inserted between the side panels 10, 20 of the stand, is fastened in the openings 17, 27 of the side panels 10, 20 of the foldable stand 100 with the use of the catch 51 . In one of the embodiments, between the side panels 10, 20, stiff, non-bendable shelves can be placed. However, in the example shown in Fig. 7 all shelves are bendable shelves 50, each of which, when straightened, forms a stiff and non-removable spacer between the side panels 10, 20. A lower wall of at least one bendable shelf 50 is bendable along at least one bending line which is parallel to the side panel. Along the bending line the central hinge 56 is formed in a plane in which the lower wall is situated. The front wall, the back wall and the top wall of the bendable shelf 50 are divided in the plane in which the bending line is located. The plane is situated at an angle to the lower wall of the bendable shelf. The top wall or the lower wall, or the side walls of the bendable shelf 50 have catches protruding from the sides of the bendable shelf 50, which are inserted into the side panels 10, 20 of the foldable stand 100. The bendable shelf 50 or bendable shelves are bent in such a way that when at least two parts of the bendable shelves 50 are brought together, the whole body 1 10 comprising the above-mentioned parts folds into a flat package, whereas when the bendable shelves 50 get straightened with at least two parts of the shelves moving away from each other, the foldable stand becomes unfolded. Each of the catches can have a bending line along which a side hinge is formed, which is situated in the plane of the side surface adjacent to the catch of the bendable shelf 50. In additional, the embodiment shown in Fig. 7 has illumination bands, for example LED bands 91 powered from a power line 90. Figs. 8 and 9 show the first embodiment of the bendable shelf of the foldable stand or rack made from bendable material. The bendable shelf 50 shown in Figs. 8 and 9 has the shape of a spatial body and comprises two panels 53, 54, that have an empty chamber inside forming an inner layer and are connected by the central hinge 56 formed along the bending line of the material from which a lower wall 151 of the bendable shelf 50 is made. At the lower part of the bendable shelf 50 there is the tilting element 69, bendable along a hinge 68. The tilting element 69 is maintained by holding elements or a supporting structure while the shelf is straightened and protrudes above a top surface of the bendable shelf 50, for example in the vertical position. The supporting structure used here can be velcro fasteners 167, 168. From two opposite sides of the bendable shelf 50 the catches 51 and stabilizing elements 52 protrude, which additionally stabilize the setting of the shelf in the side panels 10, 20 of the foldable stand 100. In another embodiment, from two opposite sides of the bendable shelf 50 only the catches 51 protrude. The walls of the bendable shelf 50, just like the entire foldable stand 100, are made of bendable material, e.g. paper, cardboard, corrugated cardboard or sheets of bendable plastic, or a combination of the above-mentioned materials, and they can have a single layer of bendable material or be multi-layer. The bendable shelf 50 comprises a top wall 153 with a top surface, a front wall 152, a back wall 154, and an inner wall155, which are divisible, and a lower wall 151 with a lower surface, which is not divisible but only bendable along the bending line. The lower wall 151 in this solution is bendable along at least one bending line, which is parallel to the side, thereby to the plane of the side panel 10 and the right side panel 20 of the foldable stand 100, along which the central hinge 56 is formed in the plane comprising the lower surface, whereas the front wall 152, the back wall 154, the inner wall 155 and the top wall 153 are divided in the plane comprising the bending line and situated at an angle of 60° - 90° in relation to the lower surface of the straightened bendable shelf 50. The top wall has catches 51 protruding beyond the sides of the bendable shelf. The catches 51 are insertable into openings located in a supporting structure of the rack or stand, particularly to the side panels 10, 20 but each of the catches 51 can have a bending line, along which a side hinge 57 is formed, facilitating the self- aligning movement of a part of the bendable shelf, i.e. the panel 53, 54 in relation to the side panel 10, 20 of the foldable stand 100. On the sides of the catches 51 , along the bending line 59, there are situated foldable wings 58, which after inserting the catch 51 into the longitudinal opening in the panel or supporting structure of the foldable rack or stand 100, return to the original position, and with their gap-like undercuts hook into the panel or supporting structure and prevent the catch from moving out of the longitudinal opening in the panel or supporting structure of the foldable rack or stand 100. The bendable shelf 50 can have the stabilizing elements 52, which additionally stabilize the placement of the shelf in the panels of the foldable stand 100, and which can move into and move out of the stabilizing openings in the panel or supporting structure of the foldable stand or rack while the stand is being folded. The shelf 50 is bent from the straightened position shown in Fig. 8 to the partially folded position shown in Fig. 9 or to fully folded position not shown.

It should be noted that the bending line, which can be present in a larger number, divides the lower wall 151 into elements, called parts or panels 53, 54, connected by a hinge, each panel having supporting elements formed from the front wall 152, the top wall 153, the back wall 154 and the inner wall 155, each of the supporting elements having inner bearing surfaces or inner supporting surfaces 143, 144. The inner supporting surfaces 143, 144, located opposite each other, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 50 from bending with the convexity downwards. To achieve the self- aligning movement in relation to the neighboring panel, a bending line between the catches and panels of the bendable shelf 50 is not necessary as even a stiff catch can align in the openings 17 and 27 of the side panels 10, 20 of the foldable stand 100.

Fig. 10 shows a bendable shelf 250 with an edge or tilting element 269, which is bendable along two bending lines. Hinges 256 are formed along the bending lines. The bendable shelf 250 shown in Fig. 10 is similar to the bendable shelf from Figs. 8 and 9 and has a shape of a spatial body, and comprises two side panels 257, 258 and one central panel 259, which can be empty inside and can be made from multi-layer cardboard whose lower layer has a hinge formed along the bending line. The central panel 259 is connected with the side panels 257 and 258 with more than one hinge 256, each of which is formed along various bending lines of the material from which the lower wall or lower surface of the bendable shelf is made. From the opposite sides of the bendable shelf 250 catches 251 and stabilizing elements 252 protrude, which facilitate the fixing of the bendable shelf into the side panels of the foldable stand. It should be noted that the number of bending lines and hinges can be any number and it can be dictated more by visual than constructional considerations. The bendable shelf 250 has the tilting element 269 at the bottom, bendable along the hinges 268.

Fig. 1 1 presents a bendable shelf 350 with a tilting element 369, bendable along hinge 368. The shelf has the shape of a spatial body comprising numerous layers of bendable material. The bendable shelf 350 comprises two parts 353, 355 in the shape of cuboid panels or cubical panels connected to one another with a hinge 356, formed along a bending line of a lower wall 384. The bending line divides the lower wall 384 into two parts. Layers 381 , 382, 383 are attached to the one part of the lower wall which is placed horizontally in Fig. 1 1 . Layers 391 , 392, 393 are attached to the another part of the lower wall which is placed vertically in Fig. 1 1 . The layers 381 , 382, 383 are glued together and the layers 391 , 392, 393 are also glued together forming separated bearing or supporting elements with inner bearing or supporting surfaces 361 , 362. The inner bearing or supporting surfaces 361 , 362, located opposite each other of the two adjacent component parts of the lower wall 384, contact and act on each other after straightening the bendable shelf and prevent the bendable shelf 350 from bending with convexity downwards. From two opposite sides 357 of the bendable shelf 350 catches 351 with wings 358 protrude. The front wall 352 and the back wall 354, as well as the inner bearing surfaces 361 , 362 of the bendable shelf 350 can be covered with paper which makes the bearing surfaces 361 , 362 resistant to deformation.

Figs. 12 and 13 present a bendable shelf 450 with a tilting element 430 which has the shape of a spatial body consisting of many layers of bendable material. The shelf 450 comprises two parts 453, 455, joined together with a hinge 456, formed along a bending line of a lower wall 493. That bending line divides the wall 493 into two movable parts, in relation of one to the other. To one of the component parts of the lower wall 493, central layers 482 and an upper layer 481 are stuck to one part of the wall at the top. To another part of the lower wall 493, central layers 492 and an upper layer 491 are stuck to it at the top. The layers 481 and 482 glued together and the layers 491 , 492 also glued together form separated bearing or supporting elements having broken inner bearing or supporting surfaces 461 , 462. The broken inner bearing or supporting surfaces 461 , 462, located opposite each other of the two adjacent component parts of the bendable shelf 450, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 450 from bending with convexity downwards. The bending of the bendable shelf 450 is further prevented by means of protrusions 463, 464 of the separated supporting elements, which with their lower surfaces lean against the top surface of the lower wall of the bendable shelf, but they are not glued to the lower wall 493. Analogically to the other solutions, from two opposite sides 457 of the bendable shelf 450 catches 451 with wings 458 protrude. A front wall 452 and a back wall 454 formed from the sides of sheet of the bendable shelf 450 can be covered by paper with inscriptions. In the front of the bendable shelf a tilting element 430, also called an edge element, is placed in a way that it is attached to the lower wall 493 by means of a binding element forming a logitudinal hinge 477 and is held up or supported by means of supporting or holding elements 471 of holding system or device, e.g. tensible elements. The tilting element 430 which forms the edge element protrudes above the upper surface of the upper wall of the shelf 450. The tilting element 430 with a central hinge 467 is held up in the vertical position by means of the holding elements 471 , for example by means of tensible elements, such as tensile cords pulled through the tilting element and openings or undercuts in the walls of the shelf and hooked onto the central flap or catch 465. Before folding the bendable shelf or folding the foldable stand into a flat package the tilting element 430 is tilted forward, according to the arrows shown in Fig. 12 to a position in which its outer surface is in the plane of the lower surface of the bendable shelf, as shown in Fig. 13. Folding the bendable shelf with the edge runs according to steps as indicated by the arrows in Figs. 12 and 13, up to the folded position.

Fig. 14 presents a pattern 410 of the lower wall 493, central belts 415, which at least partly cover the wall sides of the bendable shelf 450, the catches 451 with the wings 458 and parts of the tilting element 430 cut out from a sheet of bendable or foldable material with the outline whose shape is close to a rectangle from which the bendable shelf according to the invention shown in Figs. 12, 13 is formed. The dashed lines denote the bending lines, i.e. the lines along which the material can be bent, and the full lines denote the lines along which the sheet of bendable material is cut throughout its entire thickness. In the lower part of the pattern there is an area in a rectangular shape from which the lower wall 493 of the bendable shelf is formed. An area of the tilting element 430 adheres to the top of an indivisible area of the lower wall 493 forming a stiff and tilting element 430 after folding.

Fig. 15 presents a pattern 420 of one of the central walls 482, 492, which has the central flaps or catches 465, as well as undercuts and slots 475 designed for placing the elements of the holding device or supporting structure.

Fig. 16 presents a pattern 480 of one of the upper walls 481 , 491 with the catches 451 and with the wings 458, covering the central walls from the top.

Figs. 17 and 18 present the next embodiment of a bendable shelf 550 with a tilting element 530, which has the shape of a spatial body consisting of many layers of bendable material. In the front of the bendable shelf 550 the tilting element 530 is placed in a way that it is attached to a lower wall 593 by means of a binding element forming a logitudinal hinge 577 and is held up or supported by means of supporting or holding elements 471 The bendable shelf 550 comprises two parts 553, 555, joined by means of a hinge 556, formed along the bending line of a lower wall 593. The bending line divides the lower wall 593 into two parts with separated bearing or supporting elements having broken inner bearing or supporting surfaces 561 , 562. For a better demonstration of construction details of the shelf 550, some of its upper walls have been shown as transparent. The broken inner bearing or supporting surfaces 561 , 562, located opposite each other of the two adjacent component parts of the bendable shelf 550, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 550 from bending with convexity downwards. The bending of the bendable shelf 550 is further prevented by means of protrusions 563, 564 of the separated supporting elements, which with their lower surfaces lean against the top surface of the lower wall of the bendable shelf. Analogically to the other solutions, from two opposite sides 557 of the bendable shelf 550 catches 551 with wings 558 protrude. A front wall 552 and a back wall 554, formed at the sides of sheets of the bendable shelf 550 can be covered by paper with inscriptions. At the front of the bendable shelf 550 is placed a tilting element 530, also called edge element, in a way that it is attached to a lower wall 593 by means of a binding element forming a logitudinal hinge 577. The tilting element 530 has a central hinge 567 and is held up or supported by means of supporting or holding elements 571 in the form of a frame with torsion elements, presented in detail in Figs. 19, 20 and 21 . Torsion elements with clasps 574 are built into each of the tilting elements. Its ends, protruding beyond the torsion elements, are built into layers 582, glued together and covered with a top layer 581 and into layers 592 glued together and covered with a top layer 591 of the parts 553, 555 of the bendable shelf 550. Alternatively, they lean on the parts of the bendable shelf 550.

The supporting structure or the holding element 571 in the form of a frame 572 with torsion elements 573 is presented in Figs. 19, 20 and 21 , whose clasp 574 in the form of the letter U is built into each of the tilting elements, and its bent ends 575, protruding beyond the torsion elements 573, are built into the parts 553, 555 of the bendable shelf 550 shown in Figs. 17 and 18. Fig. 19 presents the frame 572 in a position in which the clasp 574 is close to all of the bent ends 575 and has the biggest impact on the tilting element 530. Fig. 20 presents an intermediate position of the frame 572, and Fig. 21 shows the frame 572 in a position in which the clasp 574 in the form of letter U lies in the same plane as the bent ends 575. The supporting or holding structure or elements 571 has a very simple construction and can be made from one length of steel wire.

Yet another embodiment of a bendable shelf 650 with a tilting element 630 is presented in Figs. 22 and 23. The bendable shelf 650 has the shape of a spatial body consisting of many layers of bendable material, like the bendable shelf in Figs. 17 and 18, and comprises two parts 653, 655, joined by means of a hinge 656, formed along the bending line of a lower wall 693, which divides the lower wall 693 into two component parts joined together. To one of the component parts of the lower wall 693, layers 681 , 682 are stuck to the top. To the other part of lower wall 693, layers 691 , 692 are stuck to the top. The layers 681 , 682 glued together and the layers 691 , 692 also glued together form separated bearing or supporting elements having broken inner bearing or supporting surfaces 661 , 662. The broken inner bearing or supporting surfaces 661 , 662 located opposite each other of the two adjacent components parts of the lower wall, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 650 from bending with convexity downwards. The bending of the bendable shelf 650 is further prevented by means of protrusions 663, 664 of the separated supporting elements, which with their lower surfaces lean against the top surface of the lower wall of the bendable shelf. Analogically to the other embodiments, from two opposite sides 657 of the bendable shelf 650 protrude catches 651 with wings 658. A front wall 652 and a back wall 654 of the bendable shelf 650 can be covered by paper with inscriptions. At the front of the shelf the tilting element 630 also called the edge element with a central hinge 667 is placed, which is held up or supported by means of supporting or holing structure or elements 671 comprising a wire 672 with a spring 675 in the middle. The wire 672 has an eyelet 673 inside, built in each part of the tilting element 630. In the eyelet 673 of each wire 672 a hook 674 is inserted, which has a bent end 676, built in the layers 682 glued together and covered with the top layer 681 and in the layers 692 glued together and covered with the top layer 691 of the parts 653, 655 of the bendable shelf 650.

The next embodiment of a bendable shelf 750 with a tilting element 730 is shown in Figs. 24 and 25. The bendable shelf 750 has the shape of a spatial body consisting of many layers of bendable material and comprises two parts 753, 755, joined by means of a hinge 756, formed along the bending line of a lower wall 793, which divides the lower wall 793 into two component parts joined together in self- aligning manner. To one of the component part of the lower wall 793, layers 781 , 782 are stuck to the top but in order to better present the construction details of the bendable shelf 750, in Figs. 24 and 25 the top layer 781 of the component part 755 was shown as transparent. To another part of the lower wall 793, layers 791 , 792 are stuck to the top. The layers 781 , 782, glued together, and the layers 791 , 792, also glued together form separated bearing or supporting elements having broken inner bearing or supporting surfaces 761 , 762. The broken inner supporting surfaces 761 , 762, located opposite each other of the two adjacent component parts of the lower wall, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 750 from bending with convexity downwards. The bending of the bendable shelf 750 is further prevented by means of protrusions 763, 764 of the separated bearing or supporting elements, which with their lower surfaces lean against the top surface of the lower wall 793 of the bendable shelf. Analogically to the other embodiments, from two opposite sides 757 of the bendable shelf 750 catches 751 with wings 758 protrude. A front wall 752 and a back wall 754 of the bendable shelf 750 can be covered by paper with inscriptions. At the front of the bendable shelf the tilting element 730, called the edge element, with a central hinge 767 is placed, which is held on or supported by means of supporting or holding structure 771 in a form of an openable hinge 772, shown in detail in Figs. 26 and 27, and having ports 777 and wings 773, 774, on which a locking system 775 acts. A short wing 773 of each hinge 772 is built in the layers 782 glued together and covered with the top layer 781 , a long wing 774 is built in the layers 792 glued together and covered with the top layer 791 of the parts 753, 755 of the bendable shelf 750.

The hinge 772, which performs a function of the system supporting or holding the tilting element 730 in the vertical position, presented in detail in Figs. 26 and 27, comprises the short wing 773, the long wing 774 and the locking mechanism 775. The short wing 773 and the long wing 774 on adjacent sides have ports 776, 777 in the shape of thin-walled cylinders placed rotationally on a roller 778 which has springs 779 on both ends. The springs 779 have arms whose curved ends press on the short wing 773 and the long wing 774, pressing them onto each other.

Another embodiment of a bendable shelf 850 with a tilting element 830 is shown in Figs. 28, 29, 30 and 31 . The bendable shelf 850 has the shape of a spatial body with side walls, a front wall 852 and a back wall 854, a lower wall 893, upper walls 881 , 891 and inner chambers 885, 895, which comprise a filling 889, 899 which has the form of a honeycomb. The inner walls of the filling are situated perpendicularly to the surface of the lower wall 893. The bendable shelf 850 comprises two parts 853, 855, joined by means of a hinge 856, formed along the bending line of the lower wall 893, which divides the lower wall into two component parts joined together. The upper wall 881 and the filling 889 are glued together and with one part of the lower wall 893, and likewise the upper wall 891 and the filling 899 are glued together and with another part of the lower wall 893 and form bearing or supporting elements with broken inner bearing or supporting surfaces 861 , 862. The broken inner bearing or supporting surfaces 861 , 862, located opposite each other of the two adjacent component parts 853, 855 of the lower wall 893, contact and act on each other after straightening the bendable shelf preventing the bendable shelf 850 from bending with convexity downwards. During rotation around axis 801 of the parts 853, 855, the bending of the bendable shelf 850 with the convexity downwards, is further prevented by means of protrusions 863, 864 of the separate bearing or supporting elements which are protruded out of the bending line. The same elements simultaneously facilitate the bending of the shelf 850 with the convexity upwards. The elements lean against the top surface 866 of the lower wall 893 of the bendable shelf 850 with their lower surface 865. The protrusions 863, 864 protrude from the component parts 853, 855 of the bendable shelf 850 in the plane of a straightened shelf, and at least in the plane parallel to the lower wall 893 of the shelf 850, as is the case of the shelves shown in Figs. 12 and 13, 17 and 18, 22 and 23, 24 and 25. Analogically to the other solutions, from two opposite sides 857 of the bendable shelf 850 catches 851 with wings 858 protrude. The front wall 852 and the back wall 854 of the bendable shelf 850 can be covered with paper with inscriptions. At the front of the bendable shelf the tilting element 830, also called the edge element, with a central hinge 867 is placed which is held up or supported by means of a supporting structure or holding element 871 , e.g. by means of tensionable elements, as in the case of the bendable shelf shown in Figs. 12 and 13.

Yet another embodiment of the invention, which is a set or unit 901 of a foldable stand 900 and a cooling device 905, which cools a cooling space 903, is shown in Fig. 32. The foldable stand 900 in this solution comprises a left side panel 910, a right side panel 920, and a back panel with an inner element 930 and outer element 940 of the back panel, which cover a lower space 902 and surround the cooling space 903 at three sides. In the cooling space 903 there are foldable shelves 950 placed one above the other. The shelves can be the ones presented in Figs. 8 and 9, 10, 1 1 , 12 and 13, 17 and 18, 22 and 23, 24 and 25 as well as 28, 29, 30 and 31 . The lower space 902, in which the cooling device 905 can be placed, has a front wall 960, sometimes called a base or a plinth. The cooling space 903, situated above the lower space 902, as in the case of the foldable stand from Fig. 1 , is covered with a top inner element 970 and a top stiffening element 980 from the top. In the right side panel 920 there are ventilation ports or openings which facilitate the flow of cool air through the lower space 902 and the cooling device 905. The cooling space 903 is separated from the lower space 902 by a lower inner element 965. Thanks to the fact that the lower inner element 965 is shorter than the depth of the foldable stand 900, an inlet opening and an outlet opening of a circulation stream 906 of cooling air generated by the cooling device 905 are uncovered. The circulation stream 906 of the cooling air after leaving the outlet of the cooling device 905 flows through a rear inner-wall chamber 939, and then flows through a top inner-wall chamber 979, and finally gets into a front cooling space 908 from the top. The circulation stream 906 of the cooling air transporting the cooled air to the interior of the foldable stand 900, especially to the cooling space 903, has been shown in Fig. 32 by small arrows 995, 996 and 997. The bendable shelves 950 with a tilting element in this embodiment have a smaller width, as measured from the front side of the bendable shelf to the inner element of the back panel of the foldable stand, than the width of the side panels of the foldable stand, which means that the front sides of the bendable shelves 950 are distanced backwards in relation to the front plane of the stand and the cooled air flowing down from the bendable shelves joins into a front stream of air. The cooling system whose cool air chamber formed between the inner element of the back panel and the outer element of the back panel, has the inlet situated above the outlet for the stream of cooling air generated by the cooling device, and outlets formed in the inner element of the back panel of the foldable stand and connecting the rear inner-wall chamber formed between the inner element and the outer element of the back panel with an inner space of the foldable stand located above the bendable shelves 950, from which the front stream of air flows to the inlet of the cooling device after descending from the bendable shelves 950 whose front surfaces are moved backwards in relation to the plane, in which the front panel 960 of the stand 900 is situated. During the cooling cycle, the stream of the cooling air formed at the front of the cooling unit 901 flows into the front top inlet or opening of the cooling device and is cooled by the cooling device 905 and flows out of the back top outlet of the cooling device being directed into the space formed between the inner element 930 of the back panel and the outer element 940 of the back panel, and flowing through openings in the inner element of the back panel gets between the bendable shelves 950 cooling the products placed on them.

The cooling space 903 in this embodiment is enclosed by a curtain 981 at the front. The curtain can be transparent foil of plastic or transparent belts 985 made of foil hanging from the top inner element 970 and the top stiffening element 980. The curtain 981 covers an upper part of the front panel 960 with its lower part and adheres to the front panel. Thanks to that an airtight seal of the cooling space is ensured, and the cooling air circulating in the cooling space does not go out, as well as additional non-cooled air is not taken from outside, which increases the intensity of the cooling of the products placed in the cooling space 903 of the foldable stand 900. The left side panel 910 and the right side panel 920 are wider at the top than at the bottom, which means that the width a _? of the left and right side panels 910, 920 is bigger at the top than the width a _∑ of the left and right panels 910, 920 at the bottom. This results in the depth of the cooling space 903 being bigger at the top than at the bottom, and that in turn improves the circulation of the air cooling particularly the cooling space 903.

Figs. 33 and 34 show shelves at front of which and between which spaces for cooling air flow are created. A cooling space 1003 of an embodiment of a foldable stand 1000 shown in Fig. 33 is closed at the front by a curtain 1081 . Above each shelf 1053, 1056, 1057 with catches 1051 a cooling chamber 1060 having a depth h ₂ is created and which is surrounded at sides by an inner element 1030, a right side panel (not shown), a tilting element 1052, 1054 and a left side panel 1010. To increase maintenance of a cooling process of products placed on the shelves as well as to control air volume flow around the products, the foldable stand 1000 is provided with air volumetric flow rate control arrangements. One of the air volumetric flow rate control arrangements has deviated flaps 1044 attached to openings 1033 through which a stream of cooling air flows to the space between the shelves, especially into the cooling chamber 1060 to cool products placed on the bendable shelf. The deviated flaps 1044 are attached to un upper edge of chosen openings 1034 and are deviated into a rear inner-wall chamber 1039 formed between the inner element 1030 and a rear central element 1047 placed in the front of an outer element 1040 and partially direct the stream of cooling air into space between the shelves 1056 and 1057. Another air volumetric flow rate control arrangement has diversification of distance h ₃ between an upper edge of the tilting element 1054 and the shelf 1053 situated above. This allows to change the air volumetric flow rate of cooling air streams flowing from openings 1033, 1034 having the height of hi to spaces between the shelves. The circulation stream 1006 of the cooling air transporting the cooled air to the interior of the foldable stand 1000, especially to the cooling space 1003, has been shown in Fig. 33 by small arrows 1095, 1092 and 1097. The foldable stand 1 100 shown in Fig. 34 closed at the front by a curtain 1 181 has yet another air volumetric flow rate control arrangement. This arrangement has opening size diversification which allows to change the air volumetric flow rate of cooling air streams flowing from openings 1 133, 1 134 to spaces between bendable shelves 1 153, 1 156, 1 157 with tilting elements 1 152, 1 154 and catches 1 151 . In the embodiment shown in Fig. 34 the openings 1 134 situated above the shelf 1 157 are bigger, for example have height h ₄ , than the openings 1 133 having height h ₇ situated above the shelf 1 156 therefore the flow of cooling air into a cooling chamber placed above the shelf 1 157 is more intensive than the flow of cooling air into a cooling chamber 1 160 surrounded by fragments of an inner element 1 130 and side panels, namely a left side panel 1 1 10 and a right side panel (not shown) and situated above the shelf 1 156. This results in increasing the air volumetric flow rate of cooling air stream between the shelves 1 156, 1 157 as compared to the air volumetric flow rate of cooling air stream between the shelves 1 153, 1 156. Additionally, the embodiment shown in Fig. 34 has another air volumetric flow rate control arrangement which has diversification of distance h ₆ between an upper edge of the tilting element 1 154 and the shelf 1 153 situated above. This allows also to change the air volumetric flow rate of cooling air streams flowing from the openings 1 133, 1 134 having the height h ₇ , h ₄ to spaces between the shelves. The circulation stream 1 106 of the cooling air transporting the cooled air to the interior of the foldable stand 1 100, especially to a cooling space 1 139 formed between the inner element 1 130 and the rear central element 1 147 placed at the front of an outer element 1 140 has been shown in Fig. 34 by small arrows 1 195, 1 193, 1 194 and 1 197.
