Description

The invention relates to metal racks for the sale of goods of a known modular type, usually consisting of a pair of racks, perpendicular cantilever bases are attached to their lower ends; the bases rest on the ground with the help of adjustable supports located on them, as well as are coupled and attached to the uprights; moreover, horizontal racks at different heights in the transverse direction connect two racks; on shelves, goods are displayed and placed. Two racks in the transverse direction are interconnected and stabilized with vertical backplanes.

Typically, racks are designed to hold goods weighing about 600 kg.

The rack must be quickly and safely assembled and disassembled in order to be able to adapt the display space to various needs, which may change over time.

The assembly procedure begins by attaching the bases to the uprights, taking into account that, in accordance with various solutions of the prior art, adjustable supports can only be present on the bases or also on the uprights, and that the supports can be installed on the uprights before or after the base engages with the base itself resistant.

A limitation of the prior art is that the fastening means of the base to the rack are often fixed with bolts or directly welded to the proximal end of the base itself, including a surface with a limited width of the base itself, which carries concentrated and significant loads; this can cause damage, leading to risky situations.

Currently, the size of the supports is determined in accordance with the type of rack, and often the supports have different shapes and sizes, for example, are designed for the so-called display rack with bases and shelves on both sides of the racks, or for the so-called wall shelf with bases and shelves only on one side of the racks. The first drawback of the prior art consists in the assembly and especially disassembly procedure, in that in known solutions the rack must be disassembled into all its constituent parts (racks, supports, bases) for reconfiguration.

Another disadvantage of the prior art is the fact that with the existence of several types of supports of various shapes and sizes, it may be difficult to select the right supports for a particular rack configuration. This also leads to inconvenience for the manufacturer of shelving, for which there is a need to produce and have more than one type of support.

US Patent No. 5,205,421, published in 1993 to R.T., is known in the art. BUSTOS, which describes how to connect the base to the rack with a transverse pin, the main purpose of which is to form a hinge. In accordance with the articulated joint of this patent, adjustable support means for vertically adjusting the strut itself are provided above the base. However, this adjustment does not resist angular oscillations of the stand when the base is disconnected. Even if this patent provides for the use of a supporting support at the lower end of the rack, this solution does not allow to safely disassemble the base when the rack is loaded.

ES patent No. 2160501 B1 is known in the state of the art, filed on June 30, 1999 in the name YUDIGAR. In this patent, in the upper part of the proximal end of the base there is a protruding open upward hook located in the groove for the hook, inserted into the front opening of the rack. In the lower part of the base there are transverse channels with which the corresponding channels of a pair of wings welded to the proximal end of the base are located on the same axis, and a transverse pin in the form of a bolt or other removable element is inserted into such channels. In this technical solution, the rack is not equipped with support legs, which are present only on the base. Thus, the entire weight of the rack, shelves and goods loaded on the shelves lies on the specified hook, and in particular on the specified pin; thus, disassembling the base under load shelves is absolutely impossible. Even if there was a supporting support at the lower end of the rack, separating the base from the rack would require a significant displacement of the base itself towards the ground in order to unhook the upper hook from the rack, suggesting a complex and difficult action to remove the base supports.

Patent FR No. 2956171 B1, filing date 02.10.2008 in the name of HMY, is known in the art. This patent describes a technical solution that is very close to that described in the above Spanish patent, where the base has at its proximal end an upstream hook that is open upward to support the strut, and a pair of lower wings with a hole that are located on the same axis with the corresponding transverse channels of the rack to which they are attached using a removable pin. This patent differs from the previous Spanish patent in that the said pair of lower wings contains wedge-shaped openings with an expanded part oriented toward the hook entering the rack hole and oriented downwardly narrowed part. A transverse locking pin passing through a through hole of the lower end of the rack passing through said wedge-shaped channels can extend from a free locking position at the top of said hole when the base hook is inserted into the front opening of the rack to a tightened locking position on the narrowed portion of the same wedge-shaped channels, when the stand is pushed down and the edge of the hole located above enters the groove of said hook. In order to disconnect the base from the rack, it is necessary to perform the opposite action, in which the rack must be raised, which certainly is not possible to carry out in a safe way when the rack is loaded. This patent also describes that the hook above and said pair of lower wings are formed into one metal part made of sheet steel by die cutting and bending, and having a flat part with bolt channels for fixing to the front of the distal end of the base; the lower part of the specified part has a perpendicular bend to form a base with a hole that lies and is attached by another bolt to the lower part of the proximal end of the base. The upper and lower parts of the specified part are bent so as to protrude in the front part of the specified part in order to form the specified upper upward hook and to form the specified pair of wings having wedge-shaped channels. The fastening of the specified part to the base by means of bolts or welding does not allow to distribute the stress over a significant part of the base itself, as a result of which problems arise due to concentration of the load on small fixing areas. Also, said hook, wings, and lower base of said part made by perpendicular bending of sheet steel do not have resistance to brittleness and cracks that may appear at the bending points, resulting in risky situations.

This invention relates to a system for attaching a base to a rack of a specified rack and the purpose of the claimed invention is to solve the above problems, as well as other problems using a rack having the characteristics specified in the independent claims, and preferred embodiments of which are indicated in the dependent claims.

In accordance with the claimed invention, the hook and wings of the proximal end of the base are made in the form of a single component part from pairs of metal plates fixed on opposite sides of the metal part, forming also a flat front part of the base with a stand; these plates have permanent perpendicular elongations, which are included in the corresponding longitudinal cavities of the base; they are welded to the walls of the part so that the wide part is reinforced by the proximal end of the base, and thus this system has the ability to better resist the mechanical loads of the rack.

In accordance with this invention, said lower wings are also profiled so as to function as hooks in order to facilitate the entry of a cross pin crossing the channels of the rack and the holes in the lower wings of the base, obstructing movement between the base and the rack, and providing the mechanical resistance necessary for counteraction to all mechanical loads to which the fastening is subjected as a result of its own weight and goods displayed on the shelves. By attaching the rack openings to both the upper hooks and the lower wings of the proximal end of the base, the mechanical load to which the rack is exposed is also absorbed on a large part of the rack, providing security benefits.

Moreover, the claimed invention includes a single base with a support, capable of supporting the rack regardless of its length, varying in accordance with the type of the rack - wall or display, which as a whole is attached to the lower end of the rack itself, which has special corresponding holes. The connection between the stand and the support part allows you to simply and easily center the support part in relation to the stand, and also allows you to keep two components in pairs even during the assembly and disassembly phases of the rack.

Figure 1a shows a perspective view of the four main components of the rack in accordance with the claimed invention: stand 1, support part 2 of the support, base 3 and pin 4.

Rack 1 can be of various types and sizes in accordance with the different needs of the demonstration: presumably the rack can have a height of 1 m to 3 m, a length P of about 3 cm to 12 cm, and a constant width L (see also figure 3d). Moreover, the rack 1 in the lower part of its side walls has at least a channel 5 for engaging with the base 3 and in particular for inserting the transverse pin 4. The channel 5 has a rounded shape with a beam-shaped groove 6 for the lock, for example, oriented upwards. Under the channels 5 of the rack 1, near its lower end there is at least a hole or recess 19 for connection with a rounded protrusion 10 located on the supporting part 2 (see below).

The supporting part 2 is made of a solid plate and is shaped to fit the screw support 7, which allows you to adjust the height of the rack / rack.

Figure 2 shows a perspective view of the assembled main components: stand 1, support part 2, base 3 and pin 4.

Figure 3a shows a top view of the support part 2, while figure 3b shows a bottom view of the same support part 2. The support part 2 has a square shape with four legs 8 and 9 on its sides, one foot on each side. Pairs of opposite legs 8 and 9 are the same size, different with respect to the adjacent side; the tabs 8 are longer than the tabs 9. The tabs 8 have an internal distance between themselves equal to the width 1. of the rack 1 and the base 3. The tabs 8 and 9 have a distance such that the shorter tabs 9 can freely cross laterally into the rack 1, and so that the longer legs 8 can be placed with friction on the outside of the strut 1 itself, which with its lower end lies on the supporting part 2. Moreover, the legs 8 contain at the midpoint of their inner surface a corresponding rounded protrusion 10 for connection with one of the corresponding sides s openings 19 in the rack 1. The inner edge of the higher side tabs 8 chamfered suitably to form a chamfer which facilitates insertion of the tabs with an interference fit themselves in the rack 1 from the outside.

To achieve maximum adjustment of the vertical position of the rack itself, there is a recess in the lower part of the support part 2 for the support surface of the pillar 1. The support part 2 has a protruding central part on which the threaded central channel 11 protrudes toward the lower part; the threaded rod 107 of the support 7 is inserted into it.

Figure 3c shows the support part 2 in cross section, on which you can see the position of the threaded channel 11, which first enters and then protrudes with respect to the support plane of the rack, so that its final length is such that it reliably interacts with the long part of the rod 107 legs 7.

Figure 3g shows that the set of parts formed by the supporting part 2 and the support 7 can be installed on different types of racks 1, 1 ', 11 "having different lengths P, but the same width L.

Figures 4a, 4b show a perspective view of the opposite ends of the base 3, which may have different lengths, presumably from 20 cm to 95 cm, and different heights, presumably from 10 cm to 15 cm. Such different lengths and heights are necessary for different demonstration needs . The base 3 as a whole has the shape of a parallelepiped, with protrusions at the proximal end for engagement with the strut 1. In particular, in the upper part of the proximal end of the base 3 there is a pair of hooks 12 that protrude upward and open downward, and in the lower part at the same end, there is a pair of wings 13, each of which has a channel 15 having a groove 16 for the lock on the inside. The channels 5 of the rack 1 and the channels 15 of the wings 13 of the base 3 have the same size and have locking grooves 6 and 16 of the same size and the same angular position.

Referring also to figure 16, the hooks 12 and wings 13 are made by die cutting from sheet steel, so that they are one with each other, and the two parts A and B that are the result of such die cutting, and each has one hook 12 and one wing 13 are welded to the sides of the vertical part 23 to hold at the level of the strut 1, forming the front part of the proximal end of the base 3. These perpendicular parts A and B contain plane extensions 25, 125, respectively, which are inserted into the corresponding parts of the upper and lower longitudinal x cavities of the near end of the base 3. The specified extensions 25, 125 and, if available, other parts of the three parts with hooks 12 and wings 13 are attached by welding and / or other suitable means to the walls of the longitudinal cavities. For this purpose, spot, wire or laser electric welding can be used. Figures 1a and 2 comprise weld points 27 and 127 as described above.

Figure 1B shows that the three parts A, B, 23 containing hooks 12 and wings 13 can be pre-assembled before insertion into the proximal end of base 3. Obviously, this technical solution makes it possible to produce a significant distribution of mechanical stress experienced by hooks on base 3 12 and wings 13.

Figures 1b and 1c show that the wings 13 have rounded corners, their lower side has a slight slope with a frontal rise, this side is behind the slot 26, vertically located on the same axis with the hook 12 open downward. This facilitates the assembly of the base 3 with the rack 1, This makes it easy to first insert the wings 13 into the corresponding holes 17 of the long gearing of the rack and then apply pressure to the base 3 towards the rack with the confidence that the hooks 12 will fit into their respective holes I have 14 short engagement. After the wings 13 are fully inserted into the engagement holes 17 and the lower side adjoins the slots 26, the base falls under its own weight, while the hooks 12 mesh with the bottom of the corresponding engagement holes 14. Thanks to this fastening, the base 3 is correctly positioned perpendicularly with respect to to the rack 1 and the channels 15 of the wings are correctly located on the same axis as the channels 5 of the rack 1, thereby facilitating the insertion of the pin 4 passing through these channels 5, 15, ensuring the strength of the connection m forward to the base 3 and the post 1.

Figure 5 shows the pin 4, which, in accordance with the known technical solution, has a small latch 18, protruding from its contour, due to the presence of not shown inner spring. The latch 18 has dimensions corresponding to the locking grooves 6 and 16, so as to allow easy removal during disassembly, as soon as the latch 18 is in phase with two grooves 6 and 16 (see below).

The structural strength of the base 3 with the rack 1 is also ensured by the presence of a washer 20, which prevents the accidental removal of the pin 4, if it happens that the latch 18 will be in phase with the grooves 6 and 16 (see figure 6).

Moreover, the head 21 of the pin 4 has a multi-faceted shape with two parallel surfaces 22, making it easier to grip the head 21 with a tool to rotate the specified pin 4 or to remove the pin itself from its socket during disassembly of the base 3 (see below).

The assembly of the rack in accordance with the claimed invention occurs with the following steps:

- insertion and fastening of the supporting part 2 to the lower end of the rack 1. This step is facilitated by the presence of an internal protrusion 10 on the tabs 8 of the supporting part 2, which engages the corresponding holes 19 of the rack 1 with friction;

- to the assembled set of parts, consisting of a rack 1 and a supporting part 2, the base 3 is attached using hooks 12 and wings 13. The near end of the base 3 with the specified part 23 is attached to the front of the rack 1, inserting a pair of wings 13 into the holes of the long mesh 17 and a pair of hooks 12 into the holes of the short gear 14;

- the base 3 moves towards the ground so that the hooks 12 are attached to the bottom of the meshing holes 14 and the wings 13 are attached to the bottom of the meshing holes 17, having channels 15 with channels 5 of the rack 1 along one axis; into the transverse slot formed by channels 15 the wings 13 and channels 5 of the rack 1, which demonstrate that the grooves 6 and 16 are located on the same axis to each other, the pin 4 of figure 5 is inserted without restriction, since the latch 18 is pushed into the pin 4 itself in contrast to the action of its counter spring;

- when the head 21 of the pin 4 is adjacent to the rack 1, a washer is inserted on the opposite end of the pin 4, which passes with the release of the latch 18 and is held next to the rack to ensure that it is not possible to accidentally remove the pin 4 from its socket;

- lowering and unscrewing the support 24 from the base 3 to bring it into contact with the ground and adjust the vertical position of the rack 1.

Dismantling the rack in accordance with the claimed invention occurs with the following steps:

- manually returning the latch 18 to the pin 4 and then removing the pin from the safety washer 20;

- if the latch 18 is not on the same axis with the locking grooves 6 and 16, the pin 4 is rotated using a tool for alignment between parts 18, 6, 16;

- removing the pin 4 from its slot 5, 15;

- uncoupling the base 3 from the rack 1 with the provision of lifting steps for disengaging the hooks 12 from the holes of the short mesh 14, and the wings 13 from the corresponding holes of the mesh 17, gradually moving the rack from the base to remove the same hooks 12 from the holes of the mesh 14 and wings 13 from the holes long gear 17.

One of the advantages of the claimed invention is the fact that the separation of the base 3 from its corresponding rack 1 can safely occur even if the rack is loaded with goods or assembled. This is possible due to the opening of the hooks 12 and the slots 26 of the wings 13, which makes it easy to remove the base 3 simply by lifting it after releasing it from the lateral restriction with the pin 4, and this is also possible due to the fact that the rack 1 does not lie on the base, but lies directly on the earth through its lower set of parts formed by the supporting part 2 and the support 7.

In the claimed invention, a modification can be used that replaces the pin 4 and the safety washer 20 with equivalent means, for example, a bolt or other means having the ability to form a removable bolt stopper, with safety means that prevent accidental removal.

This description relates to preferred embodiments of the invention that can be modified without deviating from the basic principles of the invention described, illustrated and indicated in the claims. In claims, the references in parentheses are only indicative and do not limit the scope of legal protection of the claims themselves.
