A storage system comprising a drawer frame and one or more boxes. The drawer frame comprises first and second guides with a U-shaped cross section, which is open towards the interior of the drawer frame such that flanges of a box can be inserted into the guides to thereby support the box slideably in the drawer frame. Clips are attached slideably to the guides and engage with the box through a clip connection device interacting with a box connection device of the box, which prevents the box from falling out of the frame.

Description

TECHNICAL FIELD

The present invention relates in general to storage systems, and in particular to modular storage systems including drawer frames and containers.

BACKGROUND

Storage systems are widely used for storing items such as linen and laundry, typically with a container in the form of a metal wire or mesh basket, or the like. One problem with such systems is how to make them more versatile and easy to handle for an end user.

SUMMARY OF INVENTION

One object of the present disclosure is therefore how to provide a system of the initially mentioned kind that is more versatile and easy to use.

This object is achieved by means of a system including a container and at least one clip. The clip is adapted to be slideably attached to a drawer frame guide, with a C-shaped portion of the clip embracing said guide, and to engage with the container with a clip connection device interacting with a container connection device of a flange of the container, such that the clip becomes fixed with regard to the container in the longitudinal direction of the guide. The clip prevents the container from being fully pulled out of the drawer frame and thus prevents the container from falling out of the frame. This makes the use of the system easier for an end user. Further, the clip assists with preventing the deformation of the container if the container is provided with a heavy load, by keeping the flange in connection with the guide of the drawer frame.

The container connection device may be an opening in a container flange, and the clip connection device may be a connector tab of the clip, which tab is adapted to enter the opening, and the end of the connector tab may comprise a tip that is directed inwards, towards the frame guide when the clip is attached to the flange.

The clip may be adapted to abut a drawer frame bar at a stop position of the box, thereby preventing the box from exiting the drawer frame.

The container may be a box that is made of injection molded plastic such as typically polypropylene, and the clip may be made of injection molded plastic such as polycarbonate.

DETAILED DESCRIPTION

The present disclosure is related to modular storage systems including drawer frames and containers. Such systems have the benefit, e.g. as compared with a traditional chests of drawers, of being configurable in various ways to address the needs of an end user. Drawer frames with metal wire and mesh baskets have been widely appreciated by users that have been able to select wire and mesh baskets with different sizes according to their needs.

From a producer point of view, the components involved have allowed for efficient distribution as empty containers can be nested inside other empty containers and since drawer frames can easily be assembled by the end user. This of course reduces the cost of the final system.

It is suggested to include plastic containers with lids in storage systems of this kind as a complement to wire and mesh containers. This would make storage systems of this kind even more versatile.

Plastic containers are relatively inexpensive to produce in large series by injection molding. Unlike a mesh or wire container, a plastic container may be made diffusion tight, and when lids are attached to the containers, the they become stackable, such that a number of containers, with items stored inside, can be stored on a small floor surface. If the storage system is used for instance in a closet, this allows the user e.g. to switch the contents of the closet from season to season.

For instance, during off-season, winter clothes may be stored at another location and, thanks to the more or less diffusion tight properties of the containers, are protected from moisture, etc. When the clothes are needed again, these containers may replace others in the drawer frame. Such a procedure is much more efficient than moving clothes from a drawer to another box, back and forth. The present disclosure provides solutions that make a plastic container more suitable for a storage system of this kind, thereby contributing to accomplishing the goal of obtaining a more efficient and versatile storage system.

The present disclosure relates to a container that is used in connection with a drawer frame. An open plastic container 1 in the form of a box is shown in FIG. 1. The box has a bottom portion 3 and first 5, 7 and second 9, 11 pairs of opposing walls rising from the bottom, thereby defining an internal space of the box.

The box has flanges at the upper edges of at least one pair of walls. The flanges extend outwards from the interior of the box in a direction substantially parallel or close to parallel with the plane in which the bottom portion 3 extends. This allows the box to be inserted in a drawer frame.

Such a drawer frame 15 is shown in FIG. 2, where five boxes 1 with applied lids are inserted in the frame. FIG. 3 shows enlarged a U shaped guide 17 in the frame, which is adapted to accommodate the flange 19 of the box, in order to support the box in the frame. For each box, the drawer frame 15 comprises a first and a second guide at each side, each having its U-shaped cross section open towards the interior of the drawer frame, such that the flanges of the box can be inserted into the frame. Such frames with guides are well known per se to support containers made of metal wire, metal mesh materials, etc.

The present disclosure seeks to improve container/drawer frame combinations of this kind. This is done by applying a clips on each side of the box that is connected both to the guide and the box.

FIG. 4 shows a top view of a box 1, which is provided with openings 21 which are located in flanges 19 at each side of the box. As illustrated in FIG. 4 and the enlarged portion shown in FIG. 5, two openings are arranged at each side and are located in the flanges close to the walls of the box, such that the openings will be accessible when the box is inserted in the drawer frame. In use, only one opening per flange will be used, and the openings are located, at the longitudinal direction along the flange, at a position that correspond to how far it is desired to allow the box to be pulled out of the drawer frame in order to access the interior of the box. In the illustrated case, the openings are located at symmetrical positions with respect to the longitudinal mid point of each flange, although this is not required. The box may be produced by injection molding of a plastic material such as polypropylene, PP.

As is more clearly shown in FIG. 5, the openings are elongated into a slot in the direction of the flange. The openings may be through holes extending through the flange, although this is not necessary.

FIG. 6A shows a perspective view of a clip 23. The clip may be made in one piece e.g. by injection molding of a plastic such a polycarbonate, PC, or a similar material. However, it would for instance also be possible to make the clip out of thin sheet metal.

The clip 23 includes in cross section a C-shaped portion 25 which in FIG. 6A is indicated with a dotted line and which is intended to surround the outer part of a drawer frame guide when in use. Thanks to this form, the clip is able to take up a load in the direction towards the interior of the drawer frame while at the same time being slideable in the longitudinal direction of the drawer frame guide 17. The clip 23 comprises a connector tab 27 at the open end of the C-shaped portion, which tab functions as a clip connection device. The opening (cf. 21, FIG. 4) in the box flange functions as a box connection device which in use cooperates with the clip connection device or connector tab 27, as will be shown. The clip 23 may further comprise a handling tab 35 that facilitates the mounting of the clip.

The end of the connector tab 27 may include a tip 29 that is directed inwardly, towards the opening of the C-shaped portion. Further, the inner of the C-shaped portion may include one or more recesses 31 that facilitate mounting of the box in the drawer frame as will now be described. The recesses are more clearly shown in the reverse perspective of FIG. 6B.

FIGS. 8-11 illustrate the attaching of a box to a drawer frame using two clips. In FIG. 8, the box 1 is about to be inserted into first and second guides 17 of the drawer frame, and one clip is attached to each of the guides. The procedure for attaching the clips is shown in greater detail in FIGS. 9 and 10. To start with, as illustrated in FIG. 9, the clip 23 is threaded over the guide 17 with the C-shaped portion being open downwards.

The clip 23 is then turned outwards until it reaches the position in FIG. 10, where the corners of the U-shaped guide 17 snap into recesses 31 inside the C-shaped portion of the clip, and the tip 29 of the connector tab rests against the edge of the guide 17, which means that the clip is stable in this position. As illustrated in FIG. 10, the box may now be inserted into the guides 17, until the opening 21 is aligned with the connector tab 27. At this point, the clip is turned back, such that the tab 27 enters the opening 21, as shown in FIG. 11. The opening may typically be about 10 mm long and the width of the tab may be about 8 mm. Other parts of the clip 23 may typically be 12 mm wide in the elongated direction of the opening. As the opening is wider than the connector tab but narrower than other parts of the clip, the clip cannot be mounted in an incorrect way. The clip on the other guide is attached in the same way.

In this position, the clip snaps into engagement with the box flange 19, and with the C-shaped portion embracing guide, if the box is pulled outwards, the clip will follow, sliding on the guide 17. However, as is evident from FIG. 8, at a front bar 33 of the drawer frame, the clip will stop and will thus stop the box from moving further outwards. Thanks to this feature, the box is prevented from being fully pulled out, such that it cannot fall out of the drawer frame.

Additionally, the clip adds some structural strength to the box 1. For instance, in the situation is illustrated in FIG. 7, a too heavy load (indicated dashed) makes the box bulge when suspended between the flanges of its long sides. A clip of the above illustrated type contributes with reducing this deformation, as the flanges are laterally fixed with regard to the guides where the clips are attached.

FIG. 12 shows a cross section through a clip 23 when attached to a frame guide 17 and the flange 19 of a box. The connector tab 27 extends through the opening 21 of the flange 19, and as can be seen, the tip 29 reaches inwards towards the frame guide 17. Thanks to the tip 29, which can function as a hook that catches the opening 21 in the flange and reduces the deformation of the box should the box be heavily loaded, the latter can carry heavier loads. This means that a plastic container may be produced with thinner goods for a given allowed storage load.

The present disclosure is not limited to the example described above and may be varied and altered in different ways within the scope of the appended claims. For instance, the opening in the container flange, in which the tab of the clip enters need not be a through hole, a recess may be sufficient. Further, the clip may abut against another item than a frame bar to prevent the container from exiting, such as for instance a stop screw or clamp that may be attached to the guide at a chosen location. In principle only one clip per container is needed to provide the stopping function.
