  DEVICE FOR HANDLING SHEET ARTICLES

  The present invention relates to handling and more particularly

  especially for the transport of sheet articles such as glazing

  and in particular the sides of motor vehicles.

  The very great fragility of this type of item and the need

  sity of frequently charging and discharging the devices used

  Often imperfect requirements arise: a

  robust construction that keeps the sheets securely as well

  if an easy accessibility and a reduced size.

  Handling such objects in wooden crates

  has many disadvantages. Not only does it require mani-

  multiple loads at loading and unloading, but the return of empty packaging poses a problem of space. The loss of time and space, the need for a large workforce make it

an expensive means of handling.

  Metal devices have been proposed, formed of a plane

  expensive fitted with only three vertical drop sides-intended to protect

  against impact the plurality of sheets resting by their edges.

  Accessibility to the sheets is facilitated for loading as

  for unloading. However, the overall dimensions at the turn remain the mid-

me.

  To remedy this drawback, we then made

  positive including folding or removable drop sides. But in one case there was a problem of mechanical deterioration, in the other

  loss of species during allies and comings. -

  French patent publication 2,506,728 describes a provision

  metal sitive which has the advantage of a small footprint & vi-

  without requiring disassembly. The proposed device comprises a floor, a rear chord and two substantially vertical side boards in use, facing each other and fixed on two opposite edges of the floor. It is characterized in that it fits into a volume substantially in the trunk of a pyramid, the floor being trapezoidal, which

  allows immediate nesting of one container in another.

  However, stalling in the nested position is not provided and there may be an accidental dislocation during an empty transport in the nested position. In addition, stacking of loaded containers is not envisaged,

  S American patent 3,193,093 proposes a device for handling

  retention of sheet articles which allows stacking as well in

  load only when empty. It consists of a base surmounted by a rear frame

  front frame. But the stacking of several devices under vacuum

  tifs can only be carried out by dismantling the front frame, which, no longer attached to the container, must be fixed during transport

  by additional means to avoid its loss.

  The invention provides a device or pallet for handling

  tion of articles in sheets, of simplified structure, stackable and stackable. The pallet according to the invention comprises a substantially rectangular base forming a floor on which the articles rest.

  their edge, a rear member which is preferably slightly

  cline outwards with respect to the vertical, a substantially rectangular upper frame whose front element is missing, four vertical uprights connecting the base and the upper frame arranged so that the two vertical uprights before determine the opening of the pallet and the two rear uprights determine the width of the base to be built in, the four uprights being provided with

  upper and lower means for positioning the cile

  lage of the pallet in stacked position, the lower means * appear

  nant to the rear uprights also allowing the positioning and setting of the pallet in the recessed position, being associated with additional means provided on the floor. The pallet is still provided with a lower structure on which it rests when it is placed directly on the ground. The lower structure allows

  also the grip of the pallet by a forklift truck.

  According to one embodiment of the pallet, the upper and lower means of the uprights allowing the positioning and the setting of one pallet with respect to the other in the two positions are, for the upper means, an upper end of the hollow upright and for

  the lower means a lower end provided with a lug suscep-

  * tible to fit into the hollow upper end of the four corresponding uprights of the underlying pallet in the stacked position,

  and the additional means are two hollow elements intended for the

  positioning and wedging of the pins of the two rear uprights of the upper pallet in the recessed position, provided on the right floor

  in front of the two rear uprights. -

  The device or pallet according to the invention is advantageously * used for the transport of side glazing. The floor is preferably formed of several beams

  profiles which can be fitted with rubber or metal racks

  plastic or, more simply, protective profiles intended to prevent slipping of the glass sheets and their direct contact with

1l Metal of the side members.

  Other characteristics and advantages of the invention appear

  will appear in the following description made in relation to the fig-

  res of an embodiment of the pallet.

  Figure 1 shows an embodiment of the pallet in view

front.

  Figure 2 shows the pallet of Figure 1 in top view.

  Figure 3 shows the palette of Figure 1 in the street of -

  c8té, in section along line A-A of Figure 1.

  Figure 4 shows in more detail an element of the puck--

  used to position and lock the eyelash in the stacked position or

castrated.

  The pallet shown in Figures 1, 2 and 3 is a pa- -

  lette 1 for handling and transporting self-closing side glazing

  mobile. This pallet includes a floor 2 formed. of several welded beams 3 on two profiled crosspieces 4, 5. The front crosspiece 4 is fixed integrally at its two ends, to two uprights 6, 7 which determine the opening of the pallet both for loading the glazing and for fitting one pallet into another

when they are empty.

  These two uprights 6, 7 are welded. At their part

  upper & a set of profiles forming an upper frame 8,

  fully open towards the front. The rear section 9 of the frame 8 is fixed to two other uprights 10, It welded to the ends of the two outer side members 12, 13 of the floor 2. The distance separating the two rear uprights 10, It is less than the distance separating the two uprights

  before 6, 7 in order to allow the embedding of two empty pallets.

  To facilitate the embedding and to help the positioning of a pallet

  in the other, the attachment of the two lateral sections 14, .15 of the box

  dre 8 with rear profile 9 uses connection elements 16, 17

  oblique, oriented inward. Floor 2 is attached to the pro-

  rear spun 9 of the frame -8 by profiles 18 slightly inclined by

  relative to the vertical forming a rear member 19.

  The four vertical uprights 6, 7, 10, 11 are hollow and their upper opening 20 can be used for positioning and wedging another pallet for stacking. This positioning is carried out by lugs 21 arranged at the lower end of the uprights, and described in more detail below in relation to the

figure 4.

  When not stacked or embedded, the pallet rests

  on the ground thanks to a metal structure 22 arranged under the plan-

  expensive 2 and comprising a lower frame 23 formed of flat irons 24 cons-

  biting a sole, The side members 3 are preferably in sufficient number and

  arranged substantially equidistant from each other to be able to

  two and possibly more, piles arranged one beside the other, glazing resting on their edge, The side members 3 constituting the floor 2 are profiles 29 provided with a groove 25 in which profiles can be mounted 26 made of rubber or plastic, various such as crém'ailllres, on

  which can rest and possibly block the edge of the

trages transported.

  Attached to the two rear uprights, two hollow elements 27; 28, similar in profile to the uprights 6, 7, 10, 11 are welded to the two outer longitudinal members 12, 13 of the floor 2. These two elements 27, 28 are used to block the lugs 21 of the upper adjacent pallet

  in recessed position. For this purpose, their spacing is the same as that-

  him two lugs 21 carried by the two lower uprights.

  In Figure 4 is shown in more detail a lower end of an upright 10, 11 carrying a positioning and locking lug. The lug 21 is arranged in the axis of the upright 10, 11 and it is welded to the flat 24 belonging to the sole of the pallet, which for this purpose has one end 29 raised so that the lower end

  of the lug 21 is at a level higher than that of the sole.

  The inclination of the dish makes it easier to position the pallet in position.

recessed or stacked position.

  The pallet according to the invention although of simple structure
