DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(10) In the following description, like numbers refer to like elements.

(11) The present disclosure relates generally to suspension arrangements intended to be used in connection with hang standards. Hang standard 1 in FIG. 1A is a non-limiting, representative example of a hang standard found in the prior art. In the illustrated example the hang standard 1 has a U-shaped cross section, although other configurations are possible, and includes one or more rows of elongated slots 3 in the mid part of the U-shaped cross section. Hang standards are typically made from sheet metal, are well known, and are typically used oriented vertically, attached to a vertical surface such as a wall or the like, or are used in a free-standing configuration with feet, for instance.

(12) FIG. 1B illustrates two hang standards 1 that are used to suspend a container 5 in the form of a wire drawer. The hang standards 1 in turn are suspended from a rail 7 attached to a wall with screws or the like. As an alternative, the hang standards 1 could be directly screwed to the wall or attached in any other manner. To each hang standard 1, a bracket 9 is attached, and at least one slider unit. In the example of FIGS. 3 to 4, the at least one slider unit is comprised of a U-shaped slider frame 11 that is attached to the brackets 9. The slider frame comprises a first slidable part of the at least one slider unit, which remains fixed with respect to the brackets. It cooperates with movable (with respect to the brackets 9) slidable parts 21, which are connected to container 5. The combination of the U-shaped frame and the slidable parts 21 allows container 5 to be carried by the brackets but also pulled outwardly form the hang standard to an extended position, like a drawer would be pulled from a chest of drawers or a cabinet. This is useful, for instance, if a plurality of such containers 5 are attached to and arranged in a stacked fashion on the same set hang standards. Pulling the container 5 out exposes its contents, which may otherwise be concealed beneath another container 5 located directly above, for instance.

(13) FIGS. 2 and 3 illustrate schematically connecting a slider frame 11 to a bracket 9 attached to a hang standard 1. The bracket 9 is connected at a proximal end to the hang standard 1 in a cantilevered manner and is usually made from sheet metal.

(14) The bracket 9 that is illustrated is a representative and non-limiting example of a prior art bracket. This particularly bracket is formed by bending sheet metal into U-shaped cross section, the depth of which tapers towards its distal end. A hook 13 is punched in each leg of the U-shape at the proximal end of the bracket 9, and each hook 13 may, as illustrated, be inserted into a respective elongated slot 3 in the hang standard 1 and is able to suspend the bracket 9 from the hang standard 1 by hanging from the bottom edge of the elongated slots 3. However, other types of brackets can be used, including ones that are flat, not U-shaped, and have a single leg.

(15) In addition to the hooks 13, auxiliary tabs 15 may, optionally, be provided below the hooks 3, which enter the elongated slots 3 directly under the ones of the hooks 13. The auxiliary tabs 15 serve to stabilize the connection and prevent the bracket 9 from moving straight upwards in relation to the hang standard 1. The tab therefore reduces the risk for an accidental disconnection of the bracket 9 from the hang standard 1.

(16) L-shaped slots 17 are provided in at least one of the upper edges of the bracket 9. The L-shaped slots 17 are intended to connect with lateral connector tabs 19 punched out on at least one of the sides of the slider frame 11. The slider frame 11 is fitted to the bracket 9 as illustrated in FIG. 3. This is done by guiding the slider frame connector tabs 19 into the L-shaped slots in the top of the bracket 9 until they reach the far end of the L-shape, at which point a locking feature (not shown) locks them in this position. This suspends the slider frame 11 from the side of the bracket 9. The L-shape of the slots 17 impede or prevent the tabs from moving straight upwards. This means that the inner part of the slider frame 11, closest to the wall, will be prevented from rotating forwardly when the mass center of the slider frame 11, including the container 5 and any objects stored therein, moves in front of the outer L-shaped slot 17.

(17) This extended position of the container is illustrated in FIG. 4, which shows a schematic top view of the prior art suspension system shown in FIGS. 2 and 3 in an assembled state. The slider frame 11 includes a slidable part that is U-shaped part which is connected to both a left and a right bracket 9 in the way described above, remaining fixed with respect to the brackets 9. The enlarged portion of the drawing showing one connector tab 19 reaching into one of the slots 17 in the bracket 9 for suspending the slider frame 11 therefrom. The right and left movable (with respect to the supporting brackets) slidable parts 21 are guided by fixed slidable parts of slider frame 11 that are adjacent to the brackets. The container 5 is attached to the right and left slidable parts 21 such that it can be pulled out to an extended position, as illustrated. Either the container 5 can be directly connected to the slidable parts 21, or a frame can be suspended in between the slidable parts 21 in which frame the container 5 can be placed. The slidable parts 21 may comprise connectors for connecting to the container 5.

(18) FIGS. 5-9 to illustrate a representative, non-limiting example of an embodiment of method and structure for connecting a slider unit to a cantilevered bracket that is easier to assemble as compared to the prior art suspension system shown in FIGS. 2 to 5, and yet safe in that it is capable of more preventing unintended rotation of the slider unit on the bracket. A slider unit is adapted in manner that allows it to be mounted on a cantilevered bracket by merely suspending it on the bracket while simultaneously interacting with a hang standard to which the bracket is mounted. This makes possible a system that reliably prevents the slider unit from rotating or pitching forwardly, and that can be adapted to work different types of bracket configurations, including brackets with two walls likes like bracket 9 and brackets with a single wall. It further, and optionally, enables the optional use of lateral connectors or other connection means for connecting the slider unit to a bracket that, at least as compared to the connection means shown in FIGS. 1 to 4, make it easier for an end user to mount a slider unit to the cantilevered bracket. Because the connection means need not (but, optionally, may) prevent the rotation of the slider unit on the bracket, the connection means may be configured to make it easier for an end user to mount reliably the slider unit on the bracket as compared to the connection means used to mount and restrain the slider unit on a bracket illustrated in connection with FIGS. 1 to 4.

(19) FIGS. 5 and 6 show, before and after assembling, a side view and partial cross section of a bracket 9 attached to a hang standard 1 when a slider unit 23 according to the present disclosure is attached to the bracket 9. This slider unit 23 comprises laterally extending connectors in the form of knobs 25 or buttons that may be inserted in slots 29 of the bracket 9, to suspend the slider unit 23 therefrom. Those slots can, as indicated with dotted lines, be L-shaped slots, like the L-shaped slots 17 of the bracket of FIG. 2. The slider unit 23 may be fitted with the known bracket 9 without modification. However, the slots 29 need not have an L-shaped configuration when used with slider unit 23.

(20) The slider unit 23 is further provided with a rear or rearwardly-extending tab 27, which, when the slider unit 23 is attached to the bracket 9, becomes positioned in register with the auxiliary tab 15 of the bracket 9. The slider unit 23 is attached to the bracket 9, and subsequently the slider unit 23 and bracket 9 combination is attached to a hang standard 1 as illustrated in FIG. 6. There, the rear tab 27 of the slider unit 23 extends into a slot 3 in the hang standard together with the auxiliary tab 15 of the bracket, as is also illustrated in the cross section of FIG. 7. By providing a rear tab 27, which may extend into the same slot 3 in the hang standard 1 as the tab 15 of the bracket 9, the slider unit 23 and its rear tab 27 are less conspicuous and provide a more favorable visual impression as compared to the prior art.

(21) In this configuration, even if the slider unit 23 carries a load with a center of mass far in front of the lateral connector, such the knob 25, that is most distant from the hang standard 1, the slider unit 23 will be kept in place as the rear tab 27 inserted in the hang standard slot 3 prevents the slider from tilting or rotating forward by reason of the rear tab 27 abutting the upper rim of the slot 3. This can be used with or without the L-shaped configuration of the bracket slots 29. In either embodiment, the connection can be made more reliable because the lever from the fulcrum, meaning the distance from the distal or front lateral connector (knob 25) to the rear tab 27, can be minimized (independent of the position of the center of mass and the size of the mass of the slider unit and the container), and the contact force between the rear tab 27 and the upper rim of the slot 3 may be maximized. If the rear tab 27 had been insertable into another slot 3, positioned higher up in the hang standard 1, the lever would have been longer, and the contact force would therefore have been smaller. Further, the contact force would not have been directed in the longitudinal direction of the hang standard 1, but at an angle thereto. Both these factors may lead to a less reliable connection between the rear tab 27 and the hang standard 1. Though optional, a connection between the rear tab 27 and the hang standard 1 in a lower one of the slots 3 occupied by the bracket 9, as shown in the figures, can be advantageous.

(22) The rear tab 27 may take up some or all of the full height of the slot 3. In one exemplary embodiment, a top edge 32 of the rear tab 27 contacts the upper edge of the slot 3 when inserted therein, which reduces movement of the rear tab 27 and thus may improve the stability of the slider unit on the bracket.

(23) In addition to the rear tab 27, the slider unit 23 may comprise, at its opposite end, a front tab 28 that is able to rest on a cut-out 30 in the distal end of the bracket 9. This may provide even more stability to the connection between the slider unit 23 and the bracket 9.

(24) As shown in the cross section of FIG. 7, it may be advantageous in some cases to provide the slider unit rear tab 27 with a bent end portion 31 that is bent to abut the rear edge of the bracket auxiliary tab 15. This prevents the slider unit 23 from slipping in a horizontal direction such that the slider unit tab 27 leaves the hang standard slot 3. This may be advantageous for instance if a bracket 9 with L-shaped slots 29 is used as indicated in FIG. 5, then this or some other locking means is suggested to avoid the knobs 25 slipping in the horizontal portion of the L-shaped slots 29.

(25) FIG. 8 shows schematically a perspective view of a slider unit 23 modified according to the present disclosure and FIG. 9 shows schematically a top view of such a slider unit. This slider may for instance being devised as illustrated in US-2019/0330902-A1 with two slidable parts, one of which is fixed to the bracket—fixed part 34—and one or more of which are moveable parts 33 configured to slide in the fixed part 34 in a manner that allows them to extend telescopically. The slider unit 23 may further comprise additional features such as braking and retracting functions (not shown) that are well known per se.

(26) The fixed slider part 34 of the slider unit 23 is provided with the rear tab 27 and connector knobs 25 (cf. FIG. 9) as discussed above. Additionally, a container or other component may be connected to the slidable parts 33 using in any means, including in the same or similar manner as previously discussed. Separate slider units 23 that are mutual mirror images, one for the bracket to the left and one for the bracket to the right, may be, optionally, provided. A U-shaped slider frame similar to the U-shaped frame 11 shown in FIG. 4, may be substituted for a pair of fixed slidable parts 34. Additionally, a front tab 28 may be provided as previously mentioned. A container 5 in the form of, for instance, a mesh or wire basket, or other type of drawer, shelf, or storage component, may located in between the telescopically moveable slider parts 33.
