Abstract
Description
- The present invention relates to a coupling device particularly but not exclusively useful for light-duty metal sets of shelves.
- Metal sets of shelves that can be assembled on site are currently widely used in the industrial and commercial field as well as in households.
- Such sets of shelves are used either to support miscellaneous lightweight items, such as for example ornaments, books, etcetera, but are also used to support items that are heavier and most of all moved frequently.
- Despite their wide variety of constructive types, said so-called "light-duty" sets of shelves are currently substantially constituted by uprights, possibly reinforced with cross-members, whereon the metallic shelves are fixed by means of coupling devices.
- Currently commercially available sets of shelves substantially have two different coupling devices.
- A first coupling device substantially entails the use of bolts insertable in holes formed in the uprights and in the shelves.
- This coupling device, despite performing its task, is not free from drawbacks, the first one residing in the considerable complexity of the assembly operations, and of the optional disassembly operations, that it entails.
- Furthermore, in sets of shelves whereon the stored items are moved often, the tightness of the bolts tends to decrease in the course of time and must be restored periodically, with an obvious waste of time and possibly, in the commercial and industrial field, of labor.
- In order to obviate the above-mentioned drawbacks, a second coupling device substantially provides for cantilevered brackets that are formed directly either in the shelf or in the uprights.
- Such cantilevered brackets fit in appropriately provided holes, which are also formed in the uprights or in the shelves.
- This second coupling device, despite being easy to assemble and disassemble, has drawbacks that can be substantially identified at a structural level.
- The bracket, in view of its cantilevered structure and because of the mechanism for its insertion in the corresponding hole, in fact undergoes, during use, considerable shearing stresses that considerably limit its overall load-bearing capacity.
- DE-A-15 54 465 discloses a coupling device for coupling upright members (1) with horizontal members (1a). The coupling device includes a U-shaped clip (6) having two parallel limbs (9) inserted through a pair of oblong apertures (5) formed in the upright member (1). Each limb (9) is folded outward to form a U-shaped wedge channel whose bottom (10) forms an angle with the longitudinal vertical axis of the upright member. The coupling device also includes a U-shaped channel assembly piece (7) fastened (e.g. by welding) to the end of the horizontal member (1a). The U-shaped piece (7) has a base (11) and parallel sides (12) whose edges are folded over in U-shaped each forming a wedge (13) which is engaged in a respective wedge channel (10) of the clip (6), thereby to connect the horizontal member (1a) to the upright member (1).
- US-A-2 147 759 discloses a demountable stand having fastening means for fastening upright walls (6,8,9a,10,13,15) of horizontal shelves (4,9,12,14) to vertical angle bar corner standards (1,2,11). The fastening means include sockets (17) pressed from the upright walls of the shelves to leave the top (17a) open and the bottom bent as a stop, and vertically disposed pairs of tongues (16) cutaway from the standards at tops and sides to leave a lower end inward shoulder with the tongues projecting thence upwardly spaced from the standard walls. The shelves may be releasably interlocked with the uprights in which the tongues are inserted in the sockets to engage or contact tightly against the upright walls of the shelves, and in which the coengaged parts may be pressed together by suitable tools to engage tightly together.
- GB-A-1 287 394 discloses a shelving frame structure having horizontal crosspieces (12) connected to upright members (10) by couplings. The couplings comprise L-shaped end portions (14) connected to the ends of the crosspieces and provided with nearly square shaped perforations (40) having tapered tongues (41 ) extending bent beyond the surface from which they project, and slots (30) formed on the face of the uprights with inwardly and outwardly projecting boundaries (31,32). To connect the crosspieces to the uprights, the tongues are slid into the slots in a direction (B) forming an angle (α) with respect to the vertical axis of the uprights.
- A principal aim of the present invention is to provide a coupling device for light-duty metal sets of shelves that solves the drawbacks described above in conventional devices, particularly by combining very easy assembly and disassembly of said sets of shelves, considerable mechanical strength, and a substantially complete lack of shearing stresses, which would severely compromise the maximum load that could be supported.

- Another object of the present invention is to provide a coupling device that is reliable over time and does not require maintenance.
- Another object of the present invention is to provide a coupling device that can be easily adapted to the various types of set of shelves provided particularly for various fields of use.

median portion 18 of thebracket 15 is substantially flat and two mutuallyopposite teeth 19 protrude from said portion, said teeth being arranged along a straight line that is substantially perpendicular to the line along which saidbracket 15 lies. - Furthermore, the
bracket 15 has lateral edges that form an angle diverging upwardly and the bisecting linecorresponding bracket 15. - It should also be noted that said interference-fit coupling, in addition to substantially completely eliminating shearing stresses, causes heavy loads arranged on a
shelf 13 to produce self-locking of thecoupling device 11. - The slotted hole related to the
female component 22 is arranged, as regards its overall longitudinal extension, in a substantially vertical direction when the set ofshelves 10 is assembled. - With particular reference to figures 5 to 7, a coupling device for light-duty metal sets of shelves, according to the invention, in a second embodiment thereof, is generally designated by the

wings 204 are formed by cutting and plastic deformation directly from the edge of thecorresponding shelf 202. - Furthermore, the cut of the part that becomes the free edge once deformation has occurred is diagonal with respect to the vertical direction, so that the final overall bulk of the
male component 203 tapers substantially downwards (angle β"). - The
