Description

A KIT OF BLANKS CONFIGURED TO BE FOLDED AND ERECTED INTO A DESK, AND SUCH A DESK Field of invention The invention relates to a kit of blanks configured to be folded and erected into a desk, the kit of blanks comprising a first blank configured to form a base of the desk and a second blank configured to form a desktop of the desk.

The invention also relates to a desk comprising a base formed of a first blank and a desktop formed ofa second blank.

The desk is especially intended to be used as a desktop for use when sitting on a floor or as an additional desktop on top of a desk or table to facilitate working standing up.

Technical Background From an ergonomical stand-point is it advisable to change ones working position frequently. To address this, many office spaces are today equipped with height-adjustable desks such that the office worker may alternate between a sitting position and a standing position.

However, such desks are often costly, and they are not a flexible solution in the sense that their position at the office is fixed. lt is e.g. common that it would be desirous to be able to alternate between a sitting position and a standing position e.g. when using a laptop computer, when writing or reading, at home. lt would e.g. often be desirous to be able to easily alternate between a sitting position and a standing position when using a laptop computer at the kitchen table.

To address this, there is e.g. in US 2018/0289147 A1 disclosed collapsible platform system for converting an underlying support surface to a standing desk. The platform system is designed as a box having a set of front, back and side wall panels connected one after the other along a first direction and a lid connected to one of the side wall panels along another direction. The side wall panels are folded relative to each other to form anopen top box and the lid is folded on top of this to form a desktop surface. To support the lid forming the desktop surface, the two side walls are designed with an over-length and are provided with an internal fold line such that they form a shallow, laying-down V-shape extend into the box-shaped space. The platform system is manufactured from a single die-cut piece of cardboard.

When designing this kind of products, the designer typically takes a plurality of design criteria in consideration.

The design should be such that there is made efficient use of the material. The design should be such that there is provided a desk which is easy to assemble while still providing a stable desk. The desk should be easy to disassemble while still providing a stable desk while being used.

Although US 2018/0289147 A1, as mentioned above, discloses a collapsible platform system for converting an underlying support surface to a standing desk, it does not adequately address the above design criteria.

Summary of invention lt is an object of the invention to provide a desk and a kit of blanks addressing at least some of the design criteria that there is made efficient use of the material, that there is provided a desk which is easy to assemble while still providing a stable desk, and that the desk should be easy to disassemble while still providing a stable desk while being used.

This object has been achieved by a kit of blanks configured to be folded and erected into a desk, the kit of blanks comprising a first blank configured to form a base of the desk and a second blank configured to form a desktop of the desk as specified in independent claim ln a preferred embodiment, the first blank comprises a set of main panels comprising a first side wall panel, a rear wall panel and a second side wall panel being foldably connected to each other along transversely extending fold lines and arranged one after the other along a longitudinal direction of the first blank as seen in a flat-laid state of the first blank.ln a preferred embodiment, the first side wall panel and the second side wall panel each has a first side provided with support edge having a mainly longitudinal extension and being intended to face upwardly and to support the second blank when the first blank is erected to form a base. ln a preferred embodiment a rearward portion of each of the first and the second side wall panels is provided with a desktop locking portion, the desktop locking portion extending transversally, as seen in a flat-laid state of the first blank, from the respective side wall panel at the first side transversely past an imaginary longitudinal extension of the respective support edge and extending longitudinally along a rearward portion of the respective support edge in a direction intended to be a forward direction and thereby form a slot between the desktop locking portion and the rearward portion of the respective support edge, the slot being configured to receive a rearward portion of the second blank when the second blank is positioned on the support edges. ln a preferred embodiment, the second blank comprises a desktop panel having an extension along the longitudinal direction and along a second transversal extension. ln accordance with a particularly preferred embodiment, the above mentioned features are all included in a single preferred embodiment. This particularly preferred embodiment including the features above may also be regarded as an inventive concept. This inventive concept may in turn be further specified in accordance with the preferred embodiments and additional features presented in the dependent claims in the description. However, it is also conceivable that as a variation one or more of the above mentioned features are omitted or altered in accordance with other preferred embodiments disclosed in the application and that such variation may in itself be regarded as an inventive concept which in turn may be further specified in accordance with the preferred embodiments and additional features presented in the dependent claims in the descriptionThe above mentioned object has accordingly been achieved by a kit of blanks configured to be folded and erected into a desk, the kit of blanks comprising a first blank configured to form a base of the desk and a second blank configured to form a desktop of the desk, the first blank comprising a set of main panels comprising a first side wall panel, a rear wall panel and a second side wall panel being foldably connected to each other along transversely extending fold lines and arranged one after the other along a longitudinal direction of the first blank as seen in a flat-laid state of the first blank, wherein the first side wall panel and the second side wall panel each has a first side provided with support edge having a mainly longitudinal extension and being intended to face upwardly and to support the second blank when the first blank is erected to form a base, wherein a rean/vard portion of each of the first and the second side wall panels is provided with a desktop locking portion, the desktop locking portion extending transversally, as seen in a flat-laid state of the first blank, from the respective side wall panel at the first side transversely past an imaginary longitudinal extension of the respective support edge and extending longitudinally along a rearward portion of the respective support edge in a direction intended to be a forward direction and thereby form a slot between the desktop locking portion and the rearvvard portion of the respective support edge, the slot being configured to receive a rearvvard portion of the second blank when the second blank is positioned on the support edges, and the second blank comprising a desktop panel having an extension along the longitudinal direction and along a second transversal extension This kit of blanks may easily be folded and assembled into a desk. The desk may e.g. be useful for cases when there is no access to a desk having sufficient height adjustability to allow alternating between working standing up and sitting down. Thus, this is advantageous from an ergonomical stand-point since it allows the user to change his/her working position frequently. The desk is e.g. useful for home offices since it makes it possible to be able to alternate between a sitting position and a standing position e.g. when using a laptop computer, when writing or reading, at home. lt makes it e.g. easy to alternate between a sitting position and a standing position when using a laptop computer at the kitchen table. lt may be noted that the desk may be used not only on ordinary desks or tables; it may basically be used to convert any underlying support surface to a standing desk.

The general design of the first blank being configured to be folded into a base allows for an efficient use of the material from which the blank is cut. The general design with a first side wall panel, a rear wall panel and a second side wall panel arranged one after the other along a longitudinal direction in combination with providing the second blank as a separate blank makes it possible to design the respective blank with a respective generally rectangular shape. The material from which the blank is cut is typically provided on rolls or as rectangular pieces of material. The general rectangular shape of the blanks reduces the amount of material that have to be cut away from the blank. The general design makes it easy to assemble the blanks into a desk. The first blank may be folded by independently folding the side wall panels one after the other or by simultaneously folding the side wall panels relative to rear wall panel. Optionally the two side wall panels may be connected to each other at the end opposite to the rear wall panel as will be described below. ln any case, the two side wall panels will present an upwardly facing support edge upon which the second blank may be positioned. The second blank will be positioned on these support edges once the desk is fully assembled. lt is also advantageous since it allows for theinstaller to temporarily rest the second blank on the support edges before the second blank is lifted and inserted to its intended final position. Since the rearward portion of each of the first and the second side wall panels is provided with a desktop locking portion forming a slot between the desktop locking portion and the rearward portion of the respective support edge the second blank may easily be positioned into the slot which aids in keeping the second blank in the intended position. The slots e.g. counter-acts the desktop from tilting relative to the base in case the user leans with his/her elbows on the front portion of the desktop. The desk is also easily disassembled by removing the second blank from the slot and thereafter once again folding the first blank back into a flat-laid state. lt may be noted that the support edges have a mainly longitudinal extension. ln a preferred embodiment, the support edges are slightly inclined such that the desktop panel will incline slightly with its front edge facing the user being slightly lower than the rear\Nard end facing away from the user. This angle oi of inclination, as measured relative to the longitudinal direction L as seen in a flat-laid state of the first blank, may e.g. be between 0-20 degrees. lt may also be noted that the longitudinal direction of the first blank as seen in a flat-laid state of the blank will generally become a horizontal direction when the blank is folded and erected into a base. The transverse direction of the first blank as seen in a flat-laid state of the blank will generally become a vertical direction when the blank is folded and erected into a base, possibly at a slight angle when the transverse direction is related to the optionally inclined support edges - as might be the case for the locking tabs. The second transverse direction will generally become a horizontal direction, possibly inclined at an angle originating from an optional inclination of the support edges.

Preferred embodiments appear in the dependent claims and in the description.

This provision of locking tabs and recesses further improves the function of keeping the second blank in the intended position on the base. Moreover, the fact that the locking tabs and recesses are provided at the rear portion relatively close to the slots yet further improves the keeping in place functionality. Since the tabs and recesses are positioned at the rear portion, the desktop is positioned into the intended position by sliding the rearvvard potion of the desktop panel along the support edges with the front portion of the desktop panel being lifted, and then as the rearvvard portion enters into the slots, the front portion of the desktop panel is lowered until this combined sliding and lowering results in that the locking tabs engages the recesses and the desktop panel becomes locked in its intended position. lt is also possible to design the height of the slots, the height of the locking tabs and the distance between the mouth of the slots and the locking tabs such that there is required a slight bending of the desktop panel in order for the desktop panel to slide into the slots with the underside of the desktop panel riding on the rear locking tabs. This slight bending may e.g. be present until the recesses reaches the locking tabs and the desktop panel may be lowered the final distance until the underside of the desktop panel rests on the support edges.

The respective rear locking tab may be positioned at a first distance from a mouth of the respective slot as measured along the respective supportedge, wherein the distance is preferably less than three times, preferably less than two times, an extension of the respective slot as measured along the respective support edge. This is preferably combined with slots having a height fitting snugly with the material thickness of the desktop panel. This may be used to provide the above mentioned bending of the desktop panel. Even if this is not the case, the positioning of the locking tabs this close to the slots still provides a strong locking functionality.

The rear recesses may be positioned at a respective second distance from a rear longitudinally extending edge of the second blank which is preferably equal to a third distance between the respective rear locking tab and a bottom of the respective slot. With this design, the rear longitudinally extending edge of the second blank will become positioned at the bottom of the respective slot when the desktop panel falls into the intended position with the rear locking tabs in the rear recesses. lt further improves the locking functionality and it also facilitates assembly since the installer can insert the desktop panel to the intended position in the forward direction into the slots and then the installer can slide the desktop panel from side to side until the intended position is found.

Each support edge of the first side wall panel respectively the second side wall panel may be provided with a transversely extending forward locking tab, the forward locking tab thereby extending upwardly from the respective support edge when the first blank is erected and folded into a base, and wherein the second blank may comprise forward recesses configured to receive the forward locking tabs when the second blank is positioned on the support edges.

This improves the function of keeping the second blank in the intended position on the base. lt may be noted that the respective forward locking tab also has an extension along the respective longitudinally extending support edge ; longitudinally as seen in a flat-laid state of the first blank.

The first and second side wall panels are configured to be connected to each other by one or more members located at a distance from the backwall panel, preferably such that the first and second side wall panels becomes fixed in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel. By connecting the first and second side wall panels to each other by one or more members located at a distance from the back wall panel a more stable base is formed. By designing the blank such that the first and second side wall panels becomes fixed in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel it is avoided that major panels of the base may be moved as a parallelogram. Preferably, the angle formed between the respective side wall panel and the back wall panel is between 95-120°.

The g, front panel connected to the first side wall panel along a transversely extending fold line on a side of the first side wall panel being opposite to the back wall panel, t front panel foldably connected to the second side wall panel along a transversely extending fold line on a side of the second side wall panel being opposite to the back wall the first and second front panels “ ' intended to be folded towards each other and thereby together form a front of the desk.

This further improves the stability of the desk.

At least one of, preferably each of, the first and second front panels may have a first side provided with a longitudinally extending support edge being intended to face upwardly and to support the second blank when the first blank is erected to form a base.

This further improves the stability of the desk.

The longitudinally extending support edge of said at least one of, preferably each of, the first and second front panels may be provided with a transversely extending locking tab, the locking tab thereby extending upwardly from the respective support edge when the first blank is erected and folded into a base, and wherein the second blank comprises recesses configured to receive the locking tabs when the second blank is positioned on the support edges. This further improves the function of keeping the second blank in the intended position on the base.

The first and second front panels have a total longitudinal extension such that they overlap each other. This further improves the stability of the desk. lt may also be used to connect the first and second front panels to each other to provide the desired fixation of the first and second side wall panels in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel.

One of the front panels may be provided with a locking tab being foldable relative to the front panel and the other one of the front panels may be provided with a locking recess configured to receive the locking tab.

The recesses of the second blank are formed as through-going cut- outs. This facilitates manufacture of the second blank. lt also facilitates assembly since the installer is through-out the installation fully aware of the location of the recesses and since installer also may get a glimpse of the locking tabs through the recesses when the intended position is nearly reached.

The support edges of the first and second wall panels may be inclined relative to the longitudinal direction such that a transversal extension of the respective the side wall panels is reduced with increased distance from the back wall panel, whereby the desktop panel will become inclined with its front portion being lower than its rear portion. This is easily achieved in the overall concept and it may be useful for many user scenarios. lt is e.g. often desirous to have a slight inclination to e.g. facilitate reading the text on a paper laying on the desk.

The back wall panel may be provided with a cut-out configured to act as a handle, the cut-out preferably being positioned on a portion of the back wall panel located between the desktop locking portions whereby the cut-out will form a handle located at a level above the desktop when the kit of blanks has been assembled into a desk. This facilitates handling of the desk, and especially if the handle is position at a level above the desktop.The first blank is preferably made of a paper-based material The second blank is preferably made of a paper-based material.

Paper-based materials may be designed such that they are light- weight. They are typically useful for application where a shape is to be cut-out from a blank piece of material. They are typically fairly easy to fold along fold lines, which e.g. may be formed by locally compressing or perforating the material. Moreover, paper-based materials are often comparably cost effective and there is in many countries established systems for recycling of paper. lt may be noted that the blanks may be made of other materials. lt may be noted that the blanks as a whole may be made of paper-based material. lt may be noted that the blanks may be made of a paper-based material coated with another material, such as a plastic coating on the inside and/or on the outside. lt may be noted that the blank need not to be made of the same material through-out.

The above mentioned object has also been achieved by a desk comprising a base formed of a first blank and a desktop formed of a second blank, the base comprising a set of main panels comprising a first side wall panel, a rear wall panel and a second side wall panel being foldably connected to each other along mainly vertically extending fold lines and arranged one after the other along a longitudinal direction of the first blank as seen in a flat-laid state of the first blank, wherein the first side wall panel and the second side wall panel each has a first side provided with support edge having a mainly longitudinal extension and facing upwardly to support the second blank, wherein a rean/vard portion of each of the first and the second side wall panels is provided with a desktop locking portion, the desktop locking portion extending upwardly from the respective side wall panel at the first side upwardly past an imaginary longitudinal extension of the respective support edge and extending longitudinally along arean/vard portion of the respective support edge in a forward direction and thereby form a slot between the desktop locking portion and the rean/vard portion of the respective support edge, the slot being configured to receive a rearvvard portion of the second blank when the second blank is positioned on the support edges, and the desktop comprising a desktop panel having an extension along the longitudinal direction and along a second transversal extension_._¿ over, t The advantages of the various features been discussed in detail in the above with reference to the kit of blanks and those advantages are equally applicable to the desk. Moreover, preferred embodiments disclosed in this disclosure in relation to the kit of blanks are equally applicable to the desk. lt may be noted that the use of first, second, third, fourth, fifth, etc. are mainly to be seen as labels facilitating reading and that it does not necessarily mean that there need to be all the intervening numbers of portions present. lt may e.g. be noted that it is contemplated to have a design where there is a first portion, a second portion, a third portion and a fifth portion, with the fourth portion being omitted. The fifth portion may e.g. connect directly to the first side wall. However, to facilitate reading, we have consistently used the numbering first, second, third, fourth, etc., as labels, and in a sense based on an embodiment including all conceivable portions.

Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, step, etc]" are to be interpreted openly as referring to at least oneinstance of said element, device, component, means, step, etc., unless explicitly stated otherwise. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless explicitly stated. The invention may also in short be said to relate to a kit of blanks comprising a first blank configured to form a base and a second blank configured to form a desktop, the first blank comprising a set of main panels comprising a first side wall panel, a rear wall panel and a second side wall panel being foldably connected to each other wherein a rearvvard portion of each of the first and the second side wall panels is provided with a desktop locking portion configured to form a slot between the desktop locking portion and a rearvvard portion of a respective support edge of the respective first and second side wall panel.

Brief description of the drawinqs The invention will by way of example be described in more detail with reference to the appended schematic drawings, which shows a presently preferred embodiment of the invention.

Figure 1 discloses an assembled desk as seen in a perspective view from above.

Figure 2 is a side view of the assembled desk of figure Figure 3 is a plan view of a blank configured to form a base of the desk of figure Figure 4 is a plan view of a blank configured to form a desktop of the desk of figure Figure 5 is a view indicating a first intermediate position during assembly of the desk of figure Figure 6 is a side view indicating a second intermediate position during assembly of the desk of figureDetailed description of preferred embodiments With reference to figure 1, there is disclosed a desk 1 comprising a base 10 formed of a first blank 100 and a desktop 20 formed of a second blank As is best shown in figure 3, the first blank 100 comprises at least a set of main panels comprising a first side wall panel 101, a rear wall panel 103 and a second side wall panel 102. These main panels 101, 102, 103 are foldably connected to each other along transversely T extending fold lines FL13, FL32 and arranged one after the other along a longitudinal direction L of the first blank 100 as seen in a flat-laid state of the first blank 100. The rear wall panel 103 is positioned between the first and the second side wall panels 101, 102 as seen in the longitudinal direction L of the blank 100 as seen in a flat-laid state of the first blank ln a preferred embodiment, the first blank 100 also comprises at least one of a first front panel 104 being foldably connected to the first side wall panel 101 along a transversely extending fold line FL14 on a side of the first side wall panel 101 being opposite to the back wall panel 103, and a second front panel 105 being foldably connected to the second side wall panel 102 along a transversely extending fold line FL25 on a side of the second side wall panel 102 being opposite to the back wall panel 103. ln the preferred embodiment shown in the figures, the first blank 100 comprises both the first and second front panels 104, 105. The first and second front panels 104, 105 are intended to be folded towards each other and thereby together form a front of the desk. ln case there is only one front panel connected to one of the side wall panels, that front panel is intended to be folded towards the other one of the side wall panels.

As shown in figure 3, the first side wall panel 101 and the second side wall panel 102 each has a first side 100u provided with support edge 111, 112. The first side 100u is as shown, and as indicated e.g. in figures 3 and 5, intended to face upwardly. The other or opposite side 100d, as seen along the transversal direction T, is intended to face downwardly and rest against a support surface, such as a floor, a desk, a table, or the like.

Each support edge 111, 112 has a mainly longitudinal extension, as seen in a flat-laid state of the blank 100 as shown in figure 3. As shown e.g. in figures 5 and 6, the support edges 111, 112 face upwardly and are intended to support the second blank lt may be noted that the support edges 111, 112 have a mainly longitudinal extension. ln a preferred embodiment, the support edges 111, 112 are slightly inclined such that the desktop panel 201a will incline slightly with its front edge facing the user being slightly lower than the rearvi/ard end facing away from the user. This angle oi of inclination may e.g. be between 0- 20 degrees as seen in the flat-laid state of the blank 100. As is indicated in figure 3, the angle of inclination is measured relative to the longitudinal direction L of the blank 100. lt may be noted that in the blank 100, such an inclination is directed such that the upper side 100u is inclined downwardly towards the other side 100d with an increasing distance of the first side wall 101 respectively the second side wall 102 from the rear wall panel 103. This may also be expressed as that the support edges 111, 112 of the first and second wall panels 101, 102 may be inclined relative to the longitudinal direction L such that a transversal extension of the respective the side wall panels 101, 102 is reduced with increased distance from the back wall panel 103, whereby the desktop panel 201 will become inclined with its front portion being lower than its rear portion. lt may be noted that it is preferred that the support edges 111, 112 extend along straight lines, irrespective of if they have a horizontal extension or if they are inclined an angle oi. lf the first and second side walls 101, 102 extend orthogonally from the rear wall panel 103 towards the front end of the desk 1, the angle oi of inclination of the support edges 111, 112 relative to the plane of the side walls 101, 102 will also be the inclination of the desktop panel 201a. lf the first and second side walls 101, 102 extend at an angle different from orthogonally from the rear wall panel 103 towards the front end of the desk 1, the inclination of the desktop panel 201a will become slightly larger than the angle oi of inclination of the support edges 111, 112 in the plane of the respective side wall 101,lt may also be noted that the Iongitudinal direction L of the first blank 100 as seen in a flat-laid state of the blank 100 will generally become a horizontal direction when the blank 100 is folded and erected into a base 10. The transverse direction T of the first blank 100 as seen in a flat-laid state of the blank 100 will generally become a vertical direction when the blank 100 is folded and erected into a base 10. However, it may be noted that if the support edges 111, 112 are inclined an angle d, a transverse extension as related to the optionally inclined support edges 111, 112 will typically extend transversely to the support edges 111, 112 and will thereby have a inclination corresponding to the angle d relative to a vertical line. This is e.g. typically true for locking tabs 131a, 132a, 131b, 132b which e.g. are shown in figure 3 and which will be discussed in detail below.

As shown in figure 3, a rearward portion 101a, 102a of each of the first and the second side wall panels 101, 102 is provided with a desktop locking portion 121, 122. The respective desktop locking portion 121, 122 extends upwardly from the respective side wall panel 101, 102 at the first side 100u upwardly past an imaginary Iongitudinal extension ofthe respective support edge 111, 112. The respective desktop locking portion 121, 122 also extends longitudinally along a rearvvard portion 111a, 112a of the respective support edge 111, 112 in a fon/vard direction and thereby form a slot 121a, 122a between the desktop locking portion 121, 122 and the rearvvard portion 111a, 112a of the respective support edge 111a, 112a. As is best shown in figure 6, the respective slot 121a, 122a is configured to receive a rearward portion 200a of the second blank 200 when the second blank 200 is positioned on the support edges 111, Each support edge 111, 112 of the first side wall panel 101 respectively the second side wall panel 102 may be provided with a transversely extending rear locking tab 131a, 132a. The rear locking tab 131a, 132a thereby extends upwardly from the respective support edge 111, 112 when the first blank 100 is erected and folded into a base 10. lt may be noted that transversely extending will in this case typically refer to a design where the locking tabs 131a, 132a extend essentially orthogonally from theextension of the support edges 111, 112. That is, if the support edges 111, 112 are inclined an angle d, the locking tabs 131a, 132a will typically extend upwardly at an angle relative to the vertical direction based on this angle d. As will be discussed in detail below, in connection with the detailed discussion concerning the second blank 200, the extension of the locking tabs 131a, 132 may take into account the inclination of the support edges 111, 112 as seen in a flat-laid state of the first blank The second blank 200 may comprise rear recesses 231 a, 232a configured to receive the rear locking tabs 131a, 132a when the second blank 200 is positioned on the support edges 111, 112. lt may be noted that the respective rear locking tab 131a, 132a also has an extension along the respective longitudinally extending support edge 111, 112 ; longitudinally as seen in a flat-laid state of the first blank 100. Consequently, also the rear recesses 231a, 232a have an extension along the respective longitudinally extending support edge 111, As is best shown in figure 6, the desktop 20 is positioned into the intended position by sliding the rearward potion 201a of the desktop panel 201 along the support edges 111, 112 with the front portion of the desktop panel 201 being lifted, and then as the reanNard portion 201a enters into the slots 121a, 122a, the front portion of the desktop panel 201 is lowered until this combined sliding and lowering results in that the locking tabs 131a, 132a engages the recesses 231a, 232a and the desktop panel 201 becomes locked in its intended position. lt is possible to design the height of the slots 121a, 122a, the height of the locking tabs 131a, 132a and the distance d1 between the mouth of the slots 121a, 122a and the locking tabs 131a, 132a such that there is required a slight bending of the rear ward portion 201a of the desktop panel 201 in order for the desktop panel 201 to slide into the slots 121a, 122a with the underside of the desktop panel 201a riding on the rear locking tabs 131a, 132a. This slight bending may e.g. be present until the recesses 231 a, 232a reaches the locking tabs 131a, 132a and the desktop panel 201a may be lowered the finaldistance until the underside of the desktop panel 201a rests on the support edges 111, The respective rear locking tab 131a, 132a is positioned at a first distance d1 from a mouth of the respective slot 121a, 122a as measured along the respective support edge 111, 112, wherein the distance d1 is preferably less than three times, preferably less than two times, an extension L121a, L122a of the respective slot 121a, 122a as measured along the respective support edge 111, 112. This is preferably combined with slots 121a, 122a having a height fitting snugly with the material thickness of the desktop panel 102a. This may be used to provide the above mentioned bending of the desktop panel 201a. Even if there is no bending necessary, the positioning of the locking tabs 131a, 132a this close to the slots 121a, 122a still provides a strong locking functionality.

The rear recesses 231 a, 232a are positioned at a respective second distance d2 from a rear longitudinally extending edge 200a' of the second blank 200 which is preferably equal to a third distance d3 between the respective rear locking tab 131a, 132a and a bottom 121a', 122a' of the respective slot 121 a, 122a. With this design, the rear longitudinally extending edge 200a' of the second blank 200 will become positioned at the bottom 121a', 122a' of the respective slot 121a, 122a when the desktop panel 201a falls into the intended position with the rear locking tabs 131a, 132a in the rear recesses 231a, 232a. lt further improves the locking functionality and it also facilitates assembly since the installer can insert the desktop panel 201 a to the intended position in the forvvard direction into the slots 121a, 122a and then the installer can slide the desktop panel 201a from side to side until the intended position is found.

Each support edge 111, 112 of the first side wall panel 101 respectively the second side wall panel 102 may be provided with a transversely extending forvvard locking tab 131b, 132b, the fon/vard locking tab 131 b, 132b thereby extending upwardly from the respective support edge 111, 112 when the first blank 100 is erected and folded into a base 10, and wherein the second blank 200 may comprise forvvard recesses 231b, 232bconfigured to receive the forward locking tabs 131a, 132a when the second blank 200 is positioned on the support edges 111, lt may be noted that the respective forward locking tab 131b, 132b also has an extension along the respective longitudinally extending support edge 111, 112; longitudinally as seen in a ﬂat-laid state of the first blank 100. Consequently, also the forward recesses 231b, 232b have an extension along the respective longitudinally extending support edge 111, The first and second side wall panels 101, 102 are configured to be connected to each other by one or more members 104, 105 located at a distance from the back wall panel 103, preferably such that the first and second side wall panels 101, 102 becomes fixed in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel By connecting the first and second side wall panels 101, 102 to each other by one or more members 104, 105 located at a distance from the back wall panel 103 a more stable base 10 is formed. By designing the blank 100 such that the first and second side wall panels 101, 102 becomes fixed in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel 103 it is avoided that major panels 101, 102, 103 of the base 10 may be moved as a parallelogram. Preferably, the angle ß formed between the respective side wall panel 101, 102 and the backwall panel 103 is between 95-120°. ln the preferred embodiment, this is accomplished by the first and second front panels 104f_, 105j.

At least one of, preferably each of, the first and second front panels 104f_, 105f_ may have a first side provided with a longitudinally extending support edge 114, 115, as seen in a flat-laid state of the blank, being intended to face upwardly and to support the second blank 200 when the first blank 100 is erected to form a base 10. When the first blank 100 has been folded and raised as a base 10, the support edge 114, 115 will extend horizontally and parallel to the major surface of the rear wall panel 103. This will also be lzo the Iongitudinal extension of the desktop panel 201. lt may be noted that it is preferred that the support edges 114, 115 extend along straight lines.

The longitudinally extending support edge 114, 115 of said at least one of, preferably each of, the first and second front panels 104j, 105: may be provided with a transversely extending locking tab 134, 135, the locking tab 134, 135 thereby extending upwardly from the respective support edge 114, 115 when the first blank 100 is erected and folded into a base 10, and wherein the second blank 200 comprises recesses 234, 235 configured to receive the locking tabs 134, 135 when the second blank 200 is positioned on the support edges 114, 115. This further improves the function of keeping the second blank 200 in the intended position on the base 10. lt may be noted that the respective locking tab 134, 135 also has an extension along the respective longitudinally extending support edge 114, 115; longitudinally as seen in a flat-laid state of the first blank 100. Consequently, also the recesses 234, 235 have an extension along the respective longitudinally extending support edge 111, As is best shown in figures 1 and 5, the first and second front panels 1041, 105f_ have preferably a total Iongitudinal extension such that they overlap each other. This further improves the stability of the desk 1. lt may also be used to connect the first and second front panels 104f, 105: to each other to provide the desired fixation of the first and second side wall panels 101, 102 in an orientation in which both form an obtuse angle or both form an acute angle, preferably both form an obtuse angle, with the back wall panel One of the front panels 105 may be provided with a locking tab or flap 145 being foldable relative to the front panel 105: and the other one of the front panels 1041 may be provided with a locking recess 144 configured to receive the locking tab or flap With reference to figure 6, the second blank 200 comprises a desktop panel 201 having an extension along the Iongitudinal direction L and along a second transversal extension T lt may also be noted that the Iongitudinal direction L of the second blank 200 as seen in a flat-laid state of the blank 100 will generally become ahorizontal direction when the blank 200 is positioned on the base 10. The second transverse direction T2 will generally become a horizontal direction, possibly inclined slightly at an angle originating from an optional inclination of the support edges 111, The recesses 231 a, 232a, 231 b, 232b, 234, 235 of the second blank 200 are preferably formed as through-going cut-outs. This facilitates manufacture of the second blank 200. lt also facilitates assembly since the installer is through-out the installation fully aware of the location of the recesses and since installer also may get a glimpse of the locking tabs through the recesses when the intended position is nearly reached. As mentioned briefly above, the locking tabs 131a, 132a, 131b, 132b of the support edges 111, 112 of the side walls 101, 102 extend preferably upwardly transversely relative to the extension of the support edges 111, 112. That is, the end edges of the locking tabs 131a, 132a, 131b, 132b extend orthogonally to the extension of the support edges 111, 112. This design of the locking tabs 131a, 132a, 131b, 132b is also advantageous since the recesses 231a, 232a, 231 b, 232b may then be cut straight through the desktop panel 201; straight through in the sense that the end edges of the recesses 231a, 232a, 231 b, 232b extend orthogonally to the major surfaces of the desktop panel 201. ln this context it may be noted that the support edges 114, 115 of the front panels 1041, 105: will extend horizontally, both as seen in a flat-laid state of the blank 100 and as seen in an assembled state of the desk 1, and the locking tabs 134, 135 extending transversely from the support edges 114, 115 will thereby extend vertically. The locking tabs 131a, 132a, 131b, 132b on the side wall panels 101, 102 and the locking tabs 134, 135 on the front wall panels 104i, 1051 preferably all have a height being about the same or slightly less than the material thickness of the desktop panel The acute or obtuse angle ß of the side wall panels 101, 102 is best shown in figure 6, where the rear recesses 231a, 232a and the forward recesses 232a, 232b are arranged along lines 231', 232' extending along the angle ß relative to the intended orientation of the rear wall panel 103. Thedashed-dotted line towards which the angles ß is indicated is an arbitrary line being parallel to the intended orientation of the rear wall panel 103. ln the coordinate system used for the second blank 200 in a flat-laid state of the second blank 200, the angle ß will become relative to the longitudinal direction L. lt may be noted that the lines 231' and 232' extend along the side wall panels 101 respectively 102 when the desk 1 is in the assembled state. The back wall panel 103 may be provided with a cut-out 153 configured to act as a handle. The cut-out 153 preferably being positioned on a portion of the back wall panel 103 located between the desktop locking portions 121, 122 whereby the cut-out 153 will form a handle located at a level above the desktop 20 when the kit of blanks has been assembled into a desk. The first blank 100 is preferably made of a paper-based material The second blank 200 is preferably made of a paper-based material. lt is contemplated that there are numerous modifications of the embodiments described herein, which are still within the scope of the invention as defined by the appended claims. ln the disclosed embodiment, the support edges 111, 112 of the first and second side wall panels 101, 102 are inclined relative to the longitudinal direction L as seen in a ﬂat-laid state of the blank 100. This is used to provide an inclination of the desktop panel 201. However, it is also conceivable to alternatively, or as a complement, design the downward or lower side 100d of the first and second side wall panels 101, 102 inclined such that this inclination reduces the transverse extension of the side wall panels 101, 102 with increasing distance from the rear wall panel 103. This will result, as seen in a flat-laid state of the blank 100, in that the lower side 100d of the rear wall panel 103 will be at a lowermost level, that the lower side 100d of the side wall panels 101, 102 will extend slightly upwardly with increasing distance from the rear wall panel 103 to a slightly higher level where they adjoin with the respective front wall panel 1041, 105f_, and then the lower side 100d of the respective front wall panel 104j, 105: will extend along the longitudinal direction L at this slightly higher level. This will also as an alternative or as acomplement result in an inclination of the desktop panel 201. One difference with this, compared to the design disclosed in the figures, is however that if the downward 100d of the side wall panels 101, 102 is inclined, the rear wall panel 103 will lean towards the user. lt is also conceivable that the rear edge 200a' of the desktop panel 201 is provided with two slits or recesses each configured to receive at least a part of the portion of the respective desktop locking portion 121, 122 extending transversely past the imaginary extension of the respective support edge 111, 112 of the first and second side wall panels 101, 102. ln such a design, the various distances referred to in the above as measured relative to the rear edge 200a' will then relate to the bottom of such slits or recesses since the bottom of the slits or recesses will in such a case be the part abutting the bottom of the slots 121a, 122a formed by the desktop locking portions 121, 122 and the rearward portions 111a, 112a of the support edges 111, Additionally, variations to the disclosed embodiments can be understood and effected by the skilled person in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims. ln the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measured cannot be used to advantage.
