Description

The present invention relates to a shelf to be hung

  walls including folding containers, trolleys for general merchandise, and

  particular shopping trolleys for the reassortment of shops,

  etc., which can be raised against the wall of

  support in non-use position.

  It is known to use removable shelves inside containers with folding walls, intended for

  contain various goods; these shelves are

  of metal wires having terminal parts

  elbows with end hooks which allow

  try to hang them on the wire walls of the container, placing them on top of each other

  on at least two levels to receive various objects.

  When the container is empty, the shelves are removed, then the walls of the container are folded and folded on the bottom of the container, in order to store it under a reduced footprint. Removable shelves of this kind are also used in shopping trolleys, more generally in storage trolleys and storage trolleys.

handling of various objects.

  In the various use cases mentioned above, the time required for setting up and removing the sets of shelves is relatively long, which causes

  significant time losses if objects placed on them

  used for example to assembly of automobiles in the chain, including bumpers, and these manipulations lead

  furthermore risks of loss of shelves. In case of posi-

  malfunction on the support walls, shelves

  can also be deformed, hindering their use.

later.

  In the particular case where the shelves are not removably mounted, but hinged permanently on the wall of a collapsible container, it uses shelf retaining hooks in the high position. But you have to have both hands simultaneously to perform the oration: one to raise the shelf and the other to maneuver the hook, which is therefore not convenient and sometimes difficult. We can

  naturally remove the shelves to obviate these inconveniences.

  but we then find the risk of losses and the

  extended handling time of removable shelves.

  The invention aims to remedy these i2conv-

  by creating a shelf that can easily be

  only one hand raised and locked in a position of non-use

against its support wall.

  The shelf referred to by the invention is of the type

  bearing sides whose end parts are bent

  substantially at right angles to the plane of the shelf itself.

  and are provided with hooks at their ends to articulate them to the metal wires of the wall of the

container or trolley.

  According to the invention, the shelf is provided

  a locking device in the raised position, including

  a latch pivotally mounted about a parallel axis

  to one of the end parts bent or constituted by

  so that the latch can switch easily

  vity around this axis when the shelf is raised against the wall, and is then placed in a perpendicular plane

  to it and in abutment against said wall, by pocketing the

  manages to switch to its horizontal position of use.

  We understand that to rotate the shelf to its position of use, simply rotate

  manually lift the latch up to a

  horizontally, in which he no longer retains

  manages which then automatically falls back into horizontal position.

  Conversely, when the shelf is raised, the latch is automatically placed by gravity in the locking position, after pivoting about its axis. Other peculiarities and advantages of

  the invention will appear during the description that will

  follow, made with reference to the accompanying drawings which is shown by way of non-limiting examples, two

  embodiments of the invention.

  FIG. 1 is a cutaway perspective view of a storage container for various objects, for example bumpers for motor vehicles, provided with

  of superposed shelves according to the invention.

  FIG. 2 is a simplified elevational view

  from the container of Figure 1, showing two pairs

  shelves arranged in it.

  FIG. 3 is a partial perspective view on an enlarged scale showing a shelf according to

  the invention in a horizontal position of use.

  FIG. 4 is a view similar to

  Figure 3 showing the shelf in raised position of non

  use, locked in that position by the

tif according to the invention.

  - Figure 5 is a perspective view of an alternative embodiment of the locking latch of the shelf. Referring to Figures 1 and 2, there is shown a container 1 shown schematically for storing and handling various objects such as by

  example of motor vehicle bumpers not shown

  felt, on a series of interior removable shelves 2a, 2b.

  The container 1, formed in known manner by four vertical walls of son :: etalliques and a

  background, receives in this example two pairs of swivel shelves

  2a, 2b hooks to the hc-izcntales crosspieces of two opposite walls 3 of the container 1. TL '- rne the other two intermediate walls, not shown, is arranged to be able to swing outwardly to allow access inside the container 1 following the direction of

  the arrow F, and the four walls are foldable on the bottom 10.

  The shelves 2a, 2b are dis-csée one above the other with a sufficient interval to allow the lower shelves 2b to be folded under the upper shelves 2a, against their support wall 3 in the position of non-use, after tilting symbolized by the arrows shown in Figure 2 to positions shown in phantom. Similarly,

  the upper shelves 2a are dimensioned and posi-

  at a chosen level so that they do not protrude above the upper edges of the walls 3 after

  folding against them in the off position.

  This example shows two pairs of superposed shelves extending along two opposite walls 3, but of course, the number of shelves can vary depending on the dimensions of the container, and

  as appropriate, objects that must be stored there.

  In known manner, each shelf 2a, 2b is formed of a reinforcement of metal son having two lateral son 4 having end portions 5 bent

  at right angles, themselves provided with end hooks.

  mites 6 allowing the hanging of the shelf on the cross

  horizontal 7 of the corresponding wall 3.

  The hooks 6 thus provide the articulation

  of the shelf around the crossbar 7, from its horizontal position

  zontale of use a. its raised vertical position.

  According to the invention, the shelf 2a or 2b is equipped with a locking device 8 of said shelf in raised position, which comprises a latch 9 mounted to pivot about an axis 11 parallel to one of the parts

  end bent 5 and secured therewith.

  In the example illustrated in Figures 3 and 4, the latch 9 is articulated on the axis 11 by means of two lateral fingers 12 through which the shaft 11, which is itself mounted inside a sleeve 13 attached to the end portion 5. The sleeve 13 is also attached to a stop 14

  solidarisée with a part 15 fixed in part 5, these diversions

  his pieces being united with each other

for example by welding.

  The stop 14 of the locking device is formed by a tab which extends perpendicularly to the end portion 5, and to the axis 11, projecting beyond it over a suitably selected distance, so as to limit the rotation of the latch 9 around the axis

  11. The latch 9 is formed of a metal plate relative to

  tively heavy, so that it can be rotated by simple

gravity around axis 11.

  The implementation of the locking device

  equipping the shelf 2a or 2b according to the invention is as follows.

  The shelf being in a horizontal position for use

  In FIG. 3, the latch 9 is in a vertical plane, held against the metal wires of the wall 3 by the stopper 14. When the shelf 2a is raised by turning it 900 around the crossbar 7, to bring it in vertical position of non-use (Figure 4), the bent end portions 5 and the axis 11 are placed in a horizontal position. During this angular displacement of the shelf, the latch 9 deviates from the wall 3, which allows it to tilt slightly by simple gravity around the axis 11. The latch 9 rotates about 900 to its position. 4, in which it is placed in a plane perpendicular to the plane of the wall 3, con-re which it is supported by its inner vertical side 9a, and prevents

  therefore the shelf 2a to switch to its horizontal position

  tal. the latch 9 thus automatically ensures the locking of the shelf in the raised vertical position

against the corresponding wall 3.

  Note that the operator has no particular maneuver to do to lock the shelf in the raised position, since the latch 9 is positioned itself by gravity to its locking position

from the shelf.

  To place it again in its horizontal position, it is sufficient for the operator to manually raise the latch 9 to its horizontal position, in which it is also stopped by the stop 14, against which is supported by the middle part of the latch 9. The shelf being released, falls back to its position

  horizontal of figure 3 by pivoting by the hooks 6.

  It is understood that it is possible under these conditions

  to close the retaining hooks 6 of the shelf so that it remains normally secured to its support wall 3, which eliminates the risk of loss

  of the shelf caused by poses and succes-

  and the corresponding loss of time.

  In addition, the locking device according to the invention has the advantage of preventing virtually any false maneuver of the operator, likely to cause deterioration of the shelf by deformation, consecutive

to a defective installation.

  In the variant embodiment illustrated in FIG. 5, the locking latch 16 is constituted by a U-shaped stirrup 17, a transverse branch of which is formed by a counterweight 18, while the horizontal parts

  of this caliper are provided with loops 19 articula-

  on the axis 11. The weight of the weight 18 is deter-

  mined so as to be sufficient to drive the latch 16 in rotation by gravity alone about the axis 11, the

  same way as in the example described above.

  The invention is not limited to the forms of

  described above and may include variances

  your execution. Thus, it is obvious that the abutment stop 14 of the locking latch can be made in any other equivalent way, and that the latch 9 can be articulated directly on the bent end portion 5, the axis

11 being deleted.

  The shelf provided with the locking device according to the invention is usable not only in foldable containers such as the container 1, but in many other applications, such as trolleys for receiving various goods, including carts for reassorting the goods. stores, fixed shelving etc .... The time saved thanks to the locking device according to the invention is particularly interesting when the container provided with such shelves

  is used in an automobile assembly line.
