Definitions

• the present invention relates to a foldable set of shelves, comprising a plurality of shelves for supporting items such as books or leaflets, and at least one support element intersecting each shelf and being pivotably arranged so as to form an X-shaped structure with the shelf, whereby the set of shelves is foldable from a display position to a storage position by adjusting a distance between two adjacent arms of said X-shaped structure.
• Foldable sets of shelves for displaying for example books and leaflets are particularly useful for movable display arrangements, being set up temporarily during e.g. a trade show or fair.
• a set of shelves it should preferably be foldable to a storage position taking up a relatively small space, so as to facilitate transport and storing.
• it should be easy to fold up to a display position, and to fold back to the storage position, in order to save time and effort when setting up or moving the movable display arrangement.
• the set of shelves should clearly display the books, leaflets etc. supported thereupon in an attractive manner.
• the set of shelves should be stable so as to be able to stand up to some pushing that might easily occur in the crowding of a trade fair without falling over.
• a set of shelves for displaying leaflets etc comprising a plurality of shelves and support elements intersecting the shelves so as to form an X-shaped structure with the shelf is known on the market today.
• the support elements are pivotally arranged to the shelves, whereby the set of shelves is foldable from a display position to a storage position by adjusting a distance between two adjacent arms of the X-shaped structure. In its display position, this shelf is arranged so that the shelves are positioned parallel to each other, thus the shelf does not take up much space. From the display position, the set of shelves is extensible to a display position, in which the shelves are positioned one above the other.
• the shelves are interconnected by pairs of flat rods, being pivotably attached to the side of the shelves by screws and nuts.
• This set of shelve although fulfilling many other desired requirements of a display shelf, is relatively expensive. Also, its construction restricts the number of materials that may be used for the shelf, since materials having relatively high weight might make the construction prone to falling over or collapsing.
• This construction minimizes the number of parts needed for the set of shelves, in that only the shelf parts and the bars are necessary to provide the foldable X- shaped structures of the set. Less parts result in that the costs for manufacturing the shelf may be reduced. Also, the construction according to the invention enables a shorter manufacturing time, since threading bars through the shelves generally require considerably less time than the known solutions using rods being attached by screws and nuts. The shorter manufacturing time may further reduce costs for the set of shelves.
• each shelf is supported by a pair of parallel bars, being pivotally arranged at opposite sides of said shelf.
• each bar has longitudinal portions forming arms of said X- sha ' ped structure, and at least one transversal attachment portion running through an opening provided in the shelf for accomplishing said pivotable arrangement.
• the transversal attachment portion in the opening will extend along a pivot axis, about which the longitudinal portion of the bar is pivotable. This construction is particularly simple and does not require much assembly time.
• a bar may be provided with a transversal attachment portion at an end of said bar, said transversal attachment portion running through an opening provided in the shelf for accomplishing pivotable arrangement of the end of the bar.
• the ends of the bars may easily be connected to shelves using transversal attachment portions.
• the foldable set of shelves is arranged so that a bar at at least one shelf, said shelf being situated between a lower shelf and a higher shelf, is pivotably connected at one end to an upper end of said lower shelf, and at the other end to a lower end of said upper shelf, and at a middle portion to the shelf which the bar intersects to form the X-shaped structure.
• the set of shelves will form a number of X-shaped structures, being interconnected via the support elements. The interconnection causes simultaneous movement of the X-shaped structure; by adjusting the distance between two adjacent arms of one X-shaped structure, the rest of the X-shaped structures of the shelf will automatically be adjusted in the same manner.
• the shelves may have edges forming an angle to a shelf plane, said edges being provided with openings through which the bars run.
• the edges may be substantially perpendicular to the shelve plane.
• the set of shelves may with advantage comprise a shelf base, to which a lowermost end of a lowermost shelf and a lowermost end of a lowermost bar is arranged.
• the distance between the lowermost ends of the lowermost shelf and bar may be adjustable so as to enable adjustment of the distance between two arms of the X-shaped structure formed between the lowermost shelf and bar. This construction enables control of the movement of the set of shelves between the different positions.
• the lowermost end of the lowermost bar or the lowermost shelf is advantageously pivotably arranged to the shelf base. Also, at least one of said lowermost ends may be slidably arranged to the shelf base.
• the set of shelves is movable from the storage position to the display position upon approaching the lowermost end of the lowermost shelf to the lowermost end of the lowermost bar at said shelf base, whereby the lowermost shelf and bar will pivot resulting in pivotal movement of all shelves and bars.
• the lowermost end of the lowermost shelf may be provided with a pair of runners for cooperation with corresponding rails in said shelf base.
• the set of shelves may conveniently be locked in its display position.
• the shelf base may be provided with an extendible support being arranged so as to extend or retract from the shelf base upon movement of the lowermost bar or the lowermost shelf in relation to the shelf base.
• the extendible support will be retracted and thus not take up much space when in the storage position. When in the display position, it will extend from the shelf base thus increasing the general support area of the set of shelves and enhancing the stability of the set of shelves.
• the automatic extension or retraction of the extendible support upon adjustment from a display position to a storage position or vice versa contributes to the easy handling of the set of shelves.
• An alternative or additional way of accomplishing locking of the set of shelves in the display position is to provide a locking means at the uppermost end of the set.
• a locking means may be provided for locking an uppermost bar and an uppermost shelf at a distance from each other in which the set of shelves assumes a display position.
• FIG. 1 is a perspective view of an embodiment of a set of shelves according to the invention when in a storage position.
• Fig. 2 is a perspective view of the set of shelves of Fig. 1 when in a display position.
• Fig. 3a is a perspective view from below of the set of shelves of fig. 1 when in the storage position.
• Fig. 3b is the same view as Fig. 3a, where the bottom portion of the shelf base has been removed.
• Fig. 4 depicts a support element of the set of shelves of Fig. 1.
• Fig. 1 depicts an embodiment of a set of shelves according to the invention when in a storage position
• Fig. 2 depicts the same set of shelves when in a display position.
• the set of shelves comprise a plurality of shelves 1, in this particular case five shelves, for supporting items such as books or leaflets.
• a support element in the form of a bar 2 intersect each shelf at a mid portion thereof so as to form an X- shaped structure with the shelf.
• the bars 2 are arranged at each shelf 1.3 being situated between a lower shelf 1.2 and a higher shelf 1.4, so as to be pivotably connected at one end to an upper end of said lower shelf 1.2, at the other end to a lower end of said higher shelf 1.4, and at a mid-portion of the shelf 1.3. Accordingly, the shelves 1 and bars 2 of the set forms a number of X-shaped structures arranged one above the other. Adjustment of the distance between two adjacent arms of one of the X- shaped structures will automatically lead to the same adjustment between the other X-shaped structures of the set.
• Each shelf is in this case actually supported by a pair of parallel bars 2, being attached to opposite sides of said shelf 1.
• the pairs of bars 2 will be arranged in a similar manner at the corresponding sides of the shelf 1 and both bars 2 will in all situations assume corresponding positions.
• each shelf 1 In the storage position, the shelves 1 are arranged in parallel to each other, and with a rather small distance in between each shelf l.
• the shelf planes form a rather small angle with a horizontal plane, and are arranged on top of each other.
• the shelves In the display position, the shelves has been pivoted so that the shelf planes form a greater angle with a horizontal plane; and assume a position in which the shelves 1 are suitable for displaying leaflets etc. Accordingly, in the storage position the set of shelves is more compact and has a considerably less height than in the display position.
• the bar 2 at each shelf 1 is running through said shelf 1 so as to accomplish the pivotable attachment. As best seen in Fig. 4, each bar 2 has longitudinal portions 2a that extend between the different shelves 1.
• each bar has a transversal attachment portion 2b located at the middle of the bar 2 for attachment to a mid-portion of the shelf 1.
• the transversal attachment portion 2b is formed by a kink on the elongated bar 2.
• the longitudinal portions 2a run along a straight line from which said kink departs to form the transversal attachment portion 2b.
• the ends of the bar 2 is provided with end transversal attachment portions 2c, for attachments to the lower end and the upper end of a higher and a lower shelf, respectively.
• the transversal attachment portions 2b and 2c run trough openings 3 provided on the shelves 1, so as to accomplish the pivotal attachment of the bar 2 to the shelves 1.
• the openings 3 through which the bars run are provided on edges provided along the sides of the shelves, each edge being substantially perpendicular to the shelf plane.
• Each shelf has openings 3 adjacent to the upper portion of the shelf, to the lower portion of the shelf, and to the mid portion of the shelf.
• most bars 2 interconnect three shelves 1: a lower shelf, a middle shelf and a top shelf.
• the lowermost bar 2 of the set of shelves is however attached to a shelf base 5 and not to a lower shelf 1.
• the uppermost bar 2 of the set of shelves is not attached to a top shelf, but extends freely and is in this case is connected to the uppermost bar 2 at the other side of the set of shelves.
• the bars in between the lowermost bar and the uppermost bar all extend from a first end transversal portion, being attached at a top portion of the lower shelf, via a first longitudinal portion to a kink, being attached at a mid-portion of the middle shelf, via a second longitudinal portion to a second end transversal portion being attached at a bottom portion of the top shelf.
• Each shelf 1 has a shelf plane portion and a support portion at an end thereof, being essentially perpendicular to the shelf plane portion.
• the shelf plane portion When in display position, the shelf plane portion will extend in a direction being more vertical than horisiontal, whereas the support portion will extend in a direction being more to the horizontal than to the vertical.
• Books or leaflets to be supported by the set of shelves are intended to be placed with their cover portions against the shelf plane portion and their end portions against the support portion.
• the lowermost end of the lowermost bar 2.1 is arranged to a shelf base 5. In this case, the location of the lowermost end of the lowermost bar 2.1 is fixed, but the bar 2.1 is pivotable about the fixed position in the shelf base 5.
• the lowermost end of the lowermost shelf 1.1 is also attached to the shelf base 5, at a distance from the lowermost bar 2.1.
• the lowermost shelf 1.1 is also pivotable in relation to the shelf base 5, but in contrast to the lowermost bar 1.1, it is slidably arranged in the shelf base 5.
• the lowermost end of the lowermost shelf 1.1 may be slided in direction towards the position of the lowermost end of the lowermost bar 2.1.
• both the shelf 1.1 and the bar 2.1 will pivot, moving the shelf 1.1 towards a more upright position. This results in simultaneous pivoting of all the shelves 1 and bars 2 of the system.
• a locking device such as a hatch. In this manner, the set of shelves may be locked in the display position.
• the locking means is released and the lowermost end of the lowermost shelf 1.1 is slided away from the lowermost bar 2.1.
• the lowermost end of the lowermost shelf is slidably arranged to the shelf base 5 by means of a pair of runners 8 running in corresponding rails in the shelf base 5.
• the locking means 6 is formed by a kink 6 of a thread structure in the shelf base 5, in which kink the runners 8 of the lowermost shelf 1.1 may be locked.
• the set of shelves is further provided with an extendible support 7 being arranged so as to extend or retract from the shelf base 5 upon the sliding movement of the lowermost shelf 1.1.

• the support 7 is formed by a thread structure being connected to the lowermost end of the lowermost shelf 1.1.
• the pair uppermost bars 2.5 are interconnected via a transverse thread member.
• a locking means 9, in this case also formed by a thread structure, is provided for locking said uppermost bar 2.5 to the uppermost end of the uppermost shelf 1.5 when the set of shelves is in display position.
• the bars 2 are preferably resililent enough so as to be conveniently threaded through the openings of the shelves, and yet not more resilient than that they provide the stability required.
• the bars 2 may be made of metal or steel such as stainless steel.
• the shelves may be manufactured of sheet metal, such as aluminium or stainless steel. The construction enables however use of a wide range of materials for the bars and the shelves.
• the bars and the shelves are interconnected adjacent to the lowermost or uppermost ends of said shelves, one could imagine that the bars and shelves are interconnected so that the shelves extend somewhat beyond the position of interconnection.
• the depicted embodiment is a preferred embodiment in which all connections between bars and shelves are made by transverse portions of the bars being introduced into openings in the shelves. This is a particularly simple and economical construction. One could however imagine that some other components are used such as a bearing in the opening of the shelves or an attachment plug attached to the ends of the bars.
