The present invention relates to a hang standard for mounting vertically in a storage system and connecting with cantilevered brackets and the like, the standard being elongated and having an approximately U-shaped cross-section with a front portion and two rearwards extending leg portions, the front portion comprising a plurality of slots as connection points and being located in a recess between first and second protruding portions, located on first and second side of the slots, respectively.
WO2019/083632 A1 discloses a wall-mounted storage system, which comprises a plurality of hang standards for vertical mounting on a wall or the like. The hang standards provide a support for cantilevered brackets, which in their turn support various storage components, such as shelves, baskets, drawers, etc. Each of the brackets utilizes slots in a single column of slots in the hang standard for inserting hooks to hang a bracket therein. The hang standard has a cross-section where each column of slots on a front face of the hang standard is recessed to obtain a visually attractive appearance, the slots being at least partly obscured by protruding portions. Brackets with attachment hooks arranged in parallel, which have been known and widely used for many years, are not compatible with such hang standards.
Disclosed are representative examples of hang standards that are compatible with brackets with parallel attachment hooks and embody various aspects that can be used alone or in various combinations to provide improved hang standards, solving various problems in the prior art.
According to one aspect, a hang standard has protruding portions on opposite sides of two or more columns of slots, defining between them a recess that is laterally continuous over the two columns of slots. It may work well with different brackets for shelves, drawers, and the like that have been sold and used for several years. Hence, the disclosed hang standard is combinable with components that the end customer may already have or with components that are already available for purchase.
This arrangement allows, optionally, the points at which the connection of brackets to a hang standard or connection points to be located within the recess, between the protruding portions. This allows the connection points and connections between brackets and the hang standard to be at least partially covered or made less conspicuous, thereby resulting in a more visually pleasing appearance when installed.
In another aspect, the bending stiffness of a hang standard with protruding portions is increased by a transition portion extending into a protruding portion, which has an outer lateral wall facing away from the front portion and an inner lateral wall facing towards the front portion, and the outer and inner lateral walls together comprising a double layer of the sheet metal. This provides an increased second moment of area. The high bending stiffness results in a high load-carrying ability while maintaining the shape of the hang standard, both as seen in its longitudinal direction and in its cross-section.
According to yet another, an outwardly extending longitudinal flange at a rear end of each of two leg portions that extend rearwardly from the front of a hang standard can be used to increase the bending stiffness of the hang standard. Additionally, the flanges may optionally, be arranged to be parallel with, and bear against, a wall on which the hang standard may be mounted, thus avoiding contacting the wall with sharp edges that could damage the surface of the wall, for example, paint or wallpaper.
In another aspect, a section of the rearward extending leg portions may be made narrower than the width of a front of a hang standard with protruding portions, thereby forming a ledge at the transition portion between each leg portion and each protruding portion. One advantage of this feature is that a covering screen or board may optionally, be attached between two hang standards by sliding, clamping, or snapping it behind the longitudinal ledge on the respective hang standard.
Furthermore, in embodiments with the protruding portions, the front portion and protruding portions can be, optionally, made to form an undercut recess. The undercut recess can be used to conceal the connection point from view and for snap fastening of various components included in the storage system. In one embodiment of such a recess, an inner lateral wall of each protruding portion is slanted to create the undercut recess. In a further embodiment, each inner lateral wall is arranged with an angle of less than 15° to a respective outer lateral wall of the protruding portion. With a limited angle between the outside and inside lateral walls of the protruding portion, the bending stiffness of the hang standard as a whole is increased, e.g., in comparison with a hang standard without protruding portions. In some preferred embodiments, the angle is 3-12°, preferably 10°.
In another embodiment, a longitudinal rib is provided in the bottom part of the recess between the columns of slots. Hereby, the fit of pre-existing brackets in the disclosed hang standard may be exact or at least improved. The disclosed hang standard may be manufactured in sheet metal with a limited thickness, and the provision of a longitudinal rib between the columns of slots may set the distance between the backside and the front side of the front portion longer than the actual thickness of the sheet metal. From the backside at the bottom of the slots, on the one hand, to the front side of the front portion at the longitudinal rib, on the other, the distance will be greater than the actual thickness of the metal. The difference will be approximately equal to the height of the rib. Hence, it is possible to make the thickness of a thinner plate appear as a thicker plate than was used previously in connection with pre-existing brackets. The longitudinal rib may for example, be embossed in the front portion between the columns of slots. Alternatively, the longitudinal rib can be created by parallel bends of the front portion of the hang standard between the columns of slots.
The hang standards with one or more of the described aspects can be, optionally, manufactured from a single sheet of folded metal.
Various options for mounting a hang standard according to any one or more of these aspects in an upright position on a wall may be provided, in addition to the prior art option of arranging fixing means, such as a screw, through the front portion, as well as engagement devices that are arranged at the rearwards extending leg portions for cooperation means for mounting the hang standard on, for example, a wall.
A hang standard with any of these aspects or features may be used or sold for use in a storage system that includes a plurality of hang standards, mounting means for interaction with each of the standards that are arranged on a wall, a plurality of brackets connected with the standards, and storage components supported by the brackets.
It is noted that combinations of one or more of the foregoing aspects may be embodied by a hang standard and are not limited to the representative embodiments that are illustrated.
All the figures are schematic, not necessarily to scale, and generally only show parts that are necessary to elucidate the embodiments, wherein other parts may be omitted.
In the following description, like numbers refer to like elements.
The present disclosure relates generally to improvements to a hang standard for mounting vertically in a storage system and connecting with cantilevered brackets and the like, the standard being elongated and having an approximately U-shaped cross-section with a front portion and two rearwards extending leg portions, the front portion comprising a plurality of slots as connection points and being located in a recess between first and second protruding portions, located on first and second side of the slots, respectively. However, such improvements may also be embodied in a hang standard for mounting vertically in a storage system and connecting with cantilevered brackets and the like, the standard being elongated and having an approximately U-shaped cross-section formed in a single piece from a strip of sheet metal, with a front portion and two rearwards extending leg portions, the front portion comprising a plurality of slots as connection points, wherein between the front portion and each of the leg portions there is provided a transition portion. One or more of the improvements may also be embodied in a hang standard for mounting vertically in a storage system and connecting with cantilevered brackets and the like, the standard being elongated and having an approximately U-shaped cross-section, with a front portion and two rearwards extending leg portions, the front portion comprising a plurality of slots as connection points for cantilevered brackets located in a recess.
The hang standard 1 has a generally U-shaped cross-section with a forwardly facing front portion 2 and two rear leg portions 3, as seen when the hang standard 1 is mounted vertically on a wall. The hang standard 1 may be formed from a single piece of sheet metal by punching and bending in several steps, thereof.
The front portion 2 is provided with a plurality of connection points for brackets at different heights to allow for a selection of the connection point for each bracket used in the system. In the embodiment shown in
The front portion 2, with the columns of slots 4, is arranged in a recess 5, which is surrounded by protruding portions 6 on each side of the front portion 2. The protruding portions 6 extend forwards from the leg portions 3 via a connecting transition portion 7 on each side of the hang standard 1.
The protruding portions 6 extend slightly outwards from the leg portions 3 at the transition portions 7. In other words, the outer transversal dimension of the hang standard 1 is wider at the protruding portions 6 than at the leg portions 3. Each protruding portion 6 has, in the illustrated embodiment, an outer wall and an inner wall. The double wall can, for example, be formed by bending of the sheet metal making up the hang standard 1.
An optional longitudinal rib 8, best seen in
One function of the longitudinal rib 8 is to make the front portion 2 thicker for the purpose of connecting brackets designed to be used with hand standards fabricated from thicker sheets of metal. Brackets that were originally designed to fit on hang standards manufactured from a thicker sheet metal may have a correct fit, without play, thanks to the provision of the rib 8. The material thickness in the illustrated case is typically in the range from 1.2-1.8 mm, preferably about 1.6 mm.
A bracket is connected to the hang standard 1 by insertion of hooks into the slots 4. The hooks each open downwards with a width of the opening closely corresponding to the thickness of the sheet metal. Hence, they will come into contact with the outer face of the front portion 2, between the columns of slots 4, as well as with the rear side of the front portion 2, at the lower end region of the slots 4. In the absence of a rib 8, the distance between the outer face and the inner side of the front portion 2, at the respective areas of contact, will correspond to the thickness of the sheet metal. If the thickness of the sheet metal closely matches the opening width of the hook, the fit will be good without play. If the sheet metal is thinner, the distance between the outer face and the inner side of the front portion 2, at the respective areas of contact, may be too small, and the bracket may appear loose. In this case, the addition of rib 8 provides a sufficient elevation for matching the distance between the two areas of contact on the hang standard 1 with the width of the hook opening on the bracket.
In at least one position, as shown in the schematic view of
The hang standard 1 may be mounted on the horizontal rail 13 by lowering in a vertical direction at the position of the notches 15. The leg portions 3 will each slide in a notch 15 until the lower flange 14b has reached its position in the engagement device 9. At this point, the hang standard 1 may be slid in the horizontal direction so that the upper flange 14a enters the engagement device 9 sideways. When both the upper 14a and the lower 14b flanges are in their respective positions, the hang standard 1 cannot be accidentally dismounted, even when it is subjected to an upwards or outwards directed force. The end tabs 17 will act as stops to keep the hang standard 1 from sliding off the rail 13 sideways.
Each protruding portion 6 has an outer wall 19 and an inner wall 20. In the example of
In a representative example of this embodiment, each inner wall 20 is arranged at an angle to the adjacent outer wall 19. The angle is sharp, preferably no more than 15°, more preferably in the range of 3-12°, and in the example shown in the figures, the angle is approximately 10°. The slanting inner walls 20 form the recess 5 with the front portion 2. The recess 5 will hereby be slightly undercut, which may make it suitable for snap fastening of various components in the storage system. If brackets 11 of a conventional type are connected to the hang standard 1, the slanting inner walls 20 may also contact the lateral sides of the brackets 11, thereby providing additional stability to the mounted brackets.
In addition, the small angle between the outer 19 and the inner 20 walls may make the protruding portion 6 perform as if it were double walled. This may provide the hang standard 1 with properties like those of an I-beam. Its flexural rigidity and bending stiffness will be greater than those of a hang standard with a basic U-shape found in the prior art.
In the middle of the front portion 2, the longitudinal rib 8 is arranged between the columns of slots 4 (not shown in
At each transition portion 7 between the leg portion 3 and the outer wall 19 of the protruding portion 6, a ledge 18 is formed due to the protruding portion 6 extending laterally outwards to a higher degree than the leg portion 3. The ledge 18 may be utilized for holding a screen or board in place between two hang standards 1 that are arranged next to one another, for instance. The screen or board may be slid in place from above or it may be snapped into its position by a slight bending thereof. As another alternative, the screen or board may be held in its position with one lateral edge next to a first hang standard 1, while a second hang standard 1 is slid sideways, along a rail 13, into its final position next to the other lateral edge of the screen or board. If needed, the screen or board may be utilized for covering the rails 13, other rails, electricity wires, pipes for water or heating etc.
The outer 19a and inner 20a walls of the protruding portions 6a are similar to those of the previously described embodiment, and transition portions 7a are provided between the protruding portions 6a and leg portions 3a. Ledges 18a are formed at the transition portions 7a. Engagement devices 9a, in the form of sockets, for engagement with a (not shown) horizontal rail are provided in the leg portions 3a, as described above, as seen in
In the embodiment of
Further, the provision of the longitudinal flanges 22 may increase the flexural rigidity of the hang standard 1a, so that higher loads may be carried by the hang standard 1a without the risk of damage thereto. The increased strength of the hang standard 1a may be due to having a cross-section like that of an I-beam.
