Description:
A wire basket shelf with partitions/side pieces.

The present invention generally relates to a wire shelf of basket shelf type having open sides and which is preferably made by folding up a front side and a rear side from a plain wire shelf blank, thereby providing an open wire basket shelf of the type in which the basket shelf is designed for being mounted on shelf brackets which can be releasably mounted on hanger bars or wall rails arranged in contact with a wall, for instance such shelf structures which are shown in the US patent 2,622,834 (B. Sparring).

The invention is more particularly concerned with a wire basket shelf which is open at the sides and which is formed with one or more partitions/side pieces, and in which the basket shelf comprises -a front side (2) having a predetermined height and which at the upper edge thereof is formed with at least one upper support wire extending in the longitudinal direction of the wire basket, -a rear side having substantially the same height as that of the front side and formed with at least one rear upper support wire extending in the longitudinal direction of the wire basket, -and a shelf bottom extending between the front and rear sides and formed with one or more intermediate support wires at predetermined places under the shelf bottom and extending in the longitudinal direction of the wire shelf, -a front and a rear lower support wire at or close the corners between the front and rear sides and the shelf bottom, -and in which at least the front side of the wire basket is arranged to be able to resiliently bow out slightly in relation to the bottom of the wire shelf.

A wire basket generally can house much more objects than a plain wire shelf and it is simpler and less expensive to manufacture than a wire basket of said priorly known box type (see e. g. figure 4 of US 5,423,437), and it can by simple means be mounted on shelf brackets.

Wire shelves are known in the art from for instance US 2,910,188 and US

3,388,808. Wire basket shelves of the said priorly known type comprise several supporting wires, generally extending parallelly with each other and parallelly to the wall, and which supporting wires are provided at the front side, or for a wire shelf of the type according to the invention having both a front side and a rear side, at the upper edges of the front side and the rear side, at or close to the edges between the front and rear sides and the bottom of the wire basket, and further comprising, between and crosswise of said supporting wires extending, further wires which form the actual front and rear sides and the bottom of the wire basket. The supporting wires preferably are provided on the exterior side of, and underneath the said further wires extending crosswise of the supporting wires which form the actual basket planes.

A disadvantage with such basket shelves of the said type, which are open at the side ends, is that objects may fall out at said side ends and that there is no possibility of providing a partition of the shelf space to provided smaller compartment units. In the above mentioned US patents 2,910,188 and 3,388,808 wire type partitions are mounted at the rear side and at the bottom of the wire shelf using different type of clamps. It may be difficult to mount said partitions, and the partitions are not safely secured to the wire shelf and can not easily be removed and The basis of the present invention therefore has been the problem of providing a wire basket shelf having partition plates, which can easily be mounted on the wire shelf without the need for any clamps or brackets, and which can quickly and easily be moved from one location to another on the wire shelf, and which may be used both as side ends for the wire basket and as partitions for providing several compartments aside of each other.

According to the invention each partition -is in the form of a substantially even plate -having substantially the same length and height as the outer dimensions of the front side, the rear side and bottom, respectively of the basket shelf and having front and rear upper support wires,

-in which the partition, at the front and rear corners thereof is formed with chamfers or locking hooks arranged to secure the partition under at least one of the front and rear upper support wires, -and in which the partition, along the bottom edge thereof, has a downwards extending rib which at the ends thereof is formed with chamfers arranged to secure the partition against the front and rear bottom support wires, and one or more downwards open recesses arranged to lockingly engage over the intermediate bottom support wire or wires.

The grooves, slots or hooks of the partition are designed for mounting of the partition against the upper and lower support wires thereby securing said partition in the horizontal direction, and also for securing the partition in the vertical direction. The locking slots or hooks at the lower edge of the partition may be ar open slots or as obliquely upwards extending recesses at the lower edge of the partition, which is/are arranged for lockingly connecting said partition to one or more of the intermediate wires of the wire basket extending underneath the basket bottom wires. In one embodiment of the invention said recesses may be formed with a snap lock hook which with some locking action snaps the partition into locking engagement with the bottom support wire or wires, thereby securing the partition in the vertical direction. Alternatively it is possible to form the looking hook or hooks at the lower edge of the partition as a straight upwards extending snap lock means. Correspondingly it is possible to form the remaining locking means as snap lock means.

Now the invention is to be described more in detail with reference to the accompanying drawings which illustrate some embodiments of a basket shelf having a partition according to the invention.

In the drawings figure 1 shows an an open basket shelf of the type concerned in the present invention, and figure 2 shows, in a perspective view and in a larger scale, one embodiment of a partition adapted to be inserted inside a basket shelf. Figure 3 shows, diagrammatically and in a perspective view, a basket shelf with a partition adapted to be mounted on suspension bars or wall

rails of priorly known type. Figure 4 is a more detailed side view of the partition according to figure 2 for use in the basket shelf shown in figure 1, and figure 5 shows an alternative embodiment of a partition. Figure 6 is a side view of a basket shelf having a partition according to figure 4 inserted therein, and in which the basket shelf with the partition is mounted on brackets onto a suspension bar or a wall rail. Figure 7 shows a basket shelf system comprising wall rail, a mounting bracket, a wire basket and a partition in an exploded view, and figure 8 shows the system of figure 7 in a late step of mounting the partition in the wire basket shelf.

The basket shelf 1 shown in the drawings is made by folding up a front side 2 and a rear side 3 from a plain wire shelf or a shelf blank, whereby a basket bottom part 4 is formed between the front side 2 and the rear side 3. A wire basket of the illustrated type comprises supporting wires at the upper edge, at or close to the bottom corners, and one or more supporting bottom wires at the underside of the basket bottom 4. In the illustrated case the basket shelf is formed with a supporting wire 5, or a pair of supporting wires, at the upper edge of the front side 2, a supporting wire 6 at the upper edge of the rear side 3, supporting wires 7 and 8 at or close to the corners between the bottom plane 4 and the front and rear sides 2 and 3, and one or more supporting wires 9 under the bottom plane 4. The supporting wires are interconnected using interconnection wires 10 thereby forming a solid integral wire basket. A large number of, preferably relatively thin, interconnection wires 10 extend transversally to the supporting wires 5-9 and are welded or otherwise connected to said supporting wires 5-9 on top of and at the inner side thereof. The basket thereby formed is stable. The front side 2 and the rear side can resiliently fold out slightly when inserting a partition in the basket shelf. The supporting wires are arranged such that it can simply, and as known in the art, be mounted on shelf brackets 11 (see figures 6-8), which are, in turn, mounted at suitable vertical levels on wall rails or suspension bars 12 of priorly known type, which are screwed or otherwise mounted against a wall.

For avoiding that material which is housed in the basket shelf falls out at the sides, or for dividing the basket shelf into several compartments, the invention

relates to a plate formed partition 13 consisting of a substantially rectangular partition plane 14 having a length and a width which substantially corresponds to the inner width and height of the basket shelf.

An first embodiment of a partition 13 is shown in figures 2,4 and 6. Figures 5,7 and 8 show further embodiments of a partition.

The partition according to figures 2,4 and 6 is formed with locking means adapted to secure same both in the horizontal and the vertical direction at a suitable place of the basket shelf, in interaction with the support wires 5-9 of the basket shelf. In the illustrated case the locking means comprises -a bow formed recess 15 at the upper edge of the rear/inner side of the partition adapted to lock the partition under the rear/inner, upper support wire 6, -a locking hook 16 at the front, upper edge of the partition and adapted to secure same by a snap lock engagement against the upper, front support wire 5 of the wire basket, -a chamfer 17 at the bottom rear part of the partition, adapted to lock the partition in the horizontal direction against the lower, inner support wire 8 of the basket shelf, -a corresponding chamfer 18 at the bottom front side of the partition adapted to lock the partition in the horizontal direction against the lower, outer support wire 7 of the basket shelf, and -one or more open slots 19 at the lower side of the partition arranged extending obliquely upwards and in the direction towards the front locking hook 16 and formed with a snap lock hook 20, and adapted to lock the partition against displacement both upwards (vertically) and horizontally by snap lock engagement against a support wire 9 extending under the bottom of the basket shelf.

The bottom part of the partition extending between said chamfers 17 and 18 provides a type of bottom rib 21 adapted to engage between a pair of interconnection wires 10 at the bottom 4 of the shelf thereby stabilizing the bottom part of the partition.

The co-operating locking means 15-20 of the partition provides a securing of the partition both in the horizontal and in the vertical direction, and the bottom rib 21, in combination with the vertical sides or the partition prevents the partition from moving laterally and from rotating in any direction in the wire shelf. The mounting of the partition 13 is made in that said partition with the upper, inner bow formed recess 15 is moved down under the upper, rear support wire 6 in between mutually adjacent cross extending interconnection wires 10, eventually while the rear side 3 of the wire shelf is resiliently fold out slightly and is returned when the recess 15 has accommodated the rear support wire. Thereafter the partition is pressed down or is rotated down so that the front locking hook 16 comes into engagement with the upper, front support wire 5. Upon a further pressing down of the front edge of the partition said partition slides down so that the locking hook 16 engages over the support wire 5 at the same time as the lower intermediate support wire 9 slides into the locking slot 19 and is secured by means of the snap lock hook 20. At the same time also the two lower, outer support wires 7 and 8 come into engagement with the rear and the front, lower chamfer 17 and 18, respectively. The partition 13 is thereby secured both in the horizontal direction and in the vertical direction in the basket shelf.

The partitions 13 can, if desired, be released oppositely to the way of mounting same, and they can optionally be moved to any desired places between pairs of interconnection wires 10.

The locking means for the partition (s) may alternatively be formed as shown in figure 5, in which the partition, both at the front and the rear upper edge is formed with identical, but mirror symmetrical, snap lock hooks 16'and 16", respectively, and in which the lower intermediate locking means is formed as a straight upwards extending snap lock means 19'having, at each side thereof a snap lock hook 20. It is also possible to form the chamfers 17 and 18 with similar snap lock means.

The partition shown in figures 7 and 8 differs from the above described partitions in that there are no locking hooks. At the upper, outer corner the

partition is formed with a recess 22 having, at the bottom thereof, a projecting tongue 23 adapted to engage under the upper, outer support wire 5. The partition is mounted as explained n connection to figure 6, but at a late stage of the mounting process said projecting tongue 23 presses the front side 2 resiliently out before said tongue 23 snaps into engagement under the upper, outer support wire 5. In this embodiment there is no need for a locking engagement at the bottom rib 21, and therefore the bottom slot 19"at said bottom rib 21 is an open slot extending straight up from the bottom edge of the bottom rib. The partition is secured against any movement upwards by the combination of the tongue 23 engaging under the outer, upper support wire 5 and the bow formed recess and the upper inner edge of the partition engaging the upper inner support wire 6.

It is obvious that the basket shelf can be formed with a different number of lower support wires, and that the partition correspondingly can be formed with an equivalent number of slots 19 having, or not having, snap lock hooks 20. It is also obvious that the wire basket can be formed with an optional number of partitions 13, for instance an outer partition at each end forming side stops in the wire basket 1, and one or more intermediate partitions for providing several compartments provided aside of each other in the basket shelf.
