SUPPORT FOR STORAGE DEVICE

NOTAMENTLY CANTILEVER TYPE

  The present invention relates to a support for a storage system and a storage system equipped with such a support.

  The invention will mainly find its interest in the production of support for cantilever type shelving systems.

  However, although particularly intended to equip a cantilever, the support may also be equipped with other storage systems and in particular for industrial storage of heavy loads and large format products.

  The supports consist of an arm intended to receive directly or indirectly the load and a connecting element for securing the support to a post of the storage device.

  Generally, the connecting element is a U-shaped portion comprising a central portion secured to the arm and two flanks, the two sides and the central portion coming to grip the upright.

  The support also comprises, at the level of the connection element, connection means to the upright and, in a conventional manner, perforations are made in the flanks corresponding to penetrations made in the upright and the whole is fixed by means of a key.

  These supports are relatively simple to make and use; However, they have various disadvantages among which the impossibility of adjusting the angle formed between the arm and the upright, so that it is necessary to have different supports depending on the nature of the loads to bear.

  For example, when it is desired to have flat loads, it is necessary to have a support whose arm forms an angle of 90 with the upright and therefore with the central part of the connection element.

  2873905 2 On the contrary, when it is desired to have on the support rolling or sliding loads, it is necessary that the arm is inclined upwards towards its free end to prevent the fall of these charges.

  Another disadvantage of this type of media is the fact that they can not get up, especially to absorb a vertical thrust on the arm.

  Indeed, during loading / unloading using forklifts in particular, it often happens that the height between two superimposed supports is low compared to the height of the load to be deposited and that, therefore, the driver types when the maneuver with the load that it must deposit in the arm of the upper support.

  Since the supports can not be raised, it follows either a degradation of the load to be deposited or a degradation of the arm or the amount that undergoes the force transmitted by the arm.

  Document EP-0,269,425 discloses a system for attaching an arm to a cantilever upright which can be very slightly inclined upwards by means of a screw whose end rests on the upright and traversing a plate with a threaded hole secured to the connection element.

  This system makes it possible to pivot the arm between a horizontal position and a slightly inclined position.

  However, it is not possible to obtain a significant angle of inclination since the upper edge of the arm comes into contact with the armature preventing a lifting more than a few degrees.

  It is therefore not possible to sufficiently damp a vertical shock on the underside of the arm with such a system.

  In addition, to allow this lifting, it is necessary to have a clearance between the armature and the U-section, which is detrimental to the stability of the arm.

  The present invention aims to overcome the aforementioned drawbacks and to provide a storage device support that can be raised in particular under the effect of a vertical force applied under the arm.

  Another object of the present invention is to provide a support whose connection with the amount does not require play to allow its pivoting.

  Another object of the present invention is to provide a support for a storage device in which the angle between the arm and the upright on which the support will be fixed is adjustable.

  The present invention also makes it possible to propose a support whose arm can be arranged against the amount of the storage device if the support is not used.

  Another object of the present invention is to provide a storage device and in particular a cantilever equipped with at least one support as mentioned above.

  The invention thus relates to a support for a storage device comprising an arm and a connecting element, said connecting element comprising a central part, integral with the arm, and two sidewalls comprising connecting means for securing in a pivot connection. to an amount of the storage device.

  According to the invention: the upper edges of the flanks of the support are located above the upper edge of the central portion, the connecting means are disposed on the flanks at a height greater than that of the upper edge of the central portion so as to allow the pivoting of the support when the latter is subject to the amount.

  The invention also relates to a cantilever equipped with at least one support as mentioned above.

  Other features and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment, in which the description is given by way of non-limiting example and with reference to the accompanying drawings, in which: FIG. 1 schematically represents a perspective view of a support according to the invention disposed on an upright, FIG. 2 represents a side view of the example represented in FIG. FIG. 3 shows, in the same view as FIG. 2, the support with the arm in the raised position under the action of a vertical force; FIG. 4 represents a second embodiment of a support that conforms to FIG. to the invention.

  Referring to Figure 1, we see a support 1 placed on an amount 2 of a storage system.

  This support 1 comprises an arm 3 for supporting directly or indirectly loads.

  The support 1 also comprises a connection element 4, this connection element 10 comprising a central part 5 and two sidewalls 6,6 '.

  In a conventional manner, the arm 3 is integral with the central portion 5.

  The flanks 6, 6 'comprise connecting means 7 to the amount 2 of the storage system.

  These connecting means 7 allow pivoting of the support 1 relative to the upright 2.

  According to the preferred embodiment illustrated in Figures 1 to 4, the securing means 7 are formed by holes 9 made in the flanks 6,6 'cooperating with a key 10 and holes in the amount 2 of the cantilever.

  However, the skilled person may also consider other elements to achieve this pivot link.

  In the known devices of the state of the art, it is impossible to raise the support 1 at an important angle since the upper edge of the central portion abuts against the upright 2.

  In the present invention, the upper edges 11 of the sidewalls 6, 6 'are situated above the upper edge 12 of the central portion 5.

  In addition, the connecting means 7 disposed on the flanks 6, 6 'are placed at a height greater than that of the upper edge 12 of the central portion 5.

  This particular structure allows the lifting of the arm 3 during a vertical shock upwards on the underside of the arm 3, since the pivoting of the arm 3 can be important before the upper face 12 comes into contact with the upright 2.

  Referring to FIG. 3, the maximum angular position of the bearing of the arm 3 can be seen.

  In this configuration, the arm 3 can be lifted at an angle α, at which angle the upper edge 12 of the central portion 5 comes into contact with the upright 2.

  The value of the angle a will depend on several parameters and in particular on the difference in height between the pivot points of the securing means 7 and the upper edge 12 of the central part.

  According to an alternative embodiment, provision may be made for the difference in height to be sufficient to allow the arm 3 to be raised at an angle of 90 making it possible to move the arm 3 parallel to said upright 2.

  Note that in the two embodiments of Figures 1 and 4 the upper face 14 of the arm 3 is at the upper edge 12 of the connecting element. This advantageous arrangement allows the angle formed between the support 1 and the upright 2 is net that is to say, it has no projection that may damage the amount or charges.

  Referring to Figure 1, we see that the upper edge 11 of the sidewalls 6,6 'and the upper edge 12 of the central portion 5 are straight.

  However, it may also be envisaged that the upper edges of the flanks 6, 6 'comprise a truncated portion 8 as shown in FIG. 4, which makes it possible in particular to soften the ridges at the level of said sidewalls 6, 6'.

  It will also be possible, according to an advantageous variant of the invention, to provide damping means between the bearing face 13 of the central portion 12 and the upright 2.

  It may also be advantageous to provide adjusting means for fixing the upright angle a.

  According to an advantageous embodiment, the adjustment means comprise a screw whose end comes to rest on the upright 2 and cooperating with a bore formed in the central portion 5. Other devices within the reach of the skilled person may also be considered to achieve these means of adjustment.

  This variant of the support 1 with adjustment means is particularly interesting since it allows either to place the arm 3 perpendicularly to the amount allowing the flat load support, or to place the arm 3 with its raised free end to support loads that can roll or slide on said arm 3.

  The invention also relates to a storage system and in particular, a cantilever equipped with at least one support 1 as mentioned above.

  Of course, the invention is not limited to the embodiment described above and other embodiments within the reach of ordinary skill in the art could have been envisaged without departing from the scope of the invention defined by the claims below.
