  Handling and storage box.

  The present invention relates to a handling and storage case opening on its front face to allow easy access to its internal volume, both for removal and preheating.

  products to be stored or handled.

  Handling and storage boxes are known whose front face comprises an upper mobile panel foldable on a lower fixed panel by pivoting about 180 degrees forward around

  an axis located substantially mid-height of said front face. How-

  However, this conception, which does not provide an important opening, leaves a constraining threshold to be crossed for heavy or voluminous objects, and does not accommodate all the modes of

loading and storage.

  Storage and handling crates are also known whose front face consists of a double door opening towards

  the front by pivoting 180 degrees or even 270 degrees

  thus placing a flap of said flaps along the side walls

  the cash register. This solution provides maximum opening, but given the large clearance required by the large travel

  door leaves, is hardly compatible with load-

  ments and / or discharges in adjacent storage or in cells of

  storage, such as automated handling operations,

in stacker cranes.

  The object of the present invention is to provide a box of

  Versatile storage and storage, ensuring optimum access and clearance in the open position, and equally usable

  manually only by means of any means of storage and

  known, for example forklift trucks, trans-

  pallets, conveyor belts or rollers cranes, etc. For this purpose, the handling and storage case opening in double door on its front face, according to the present invention, is remarkable in that the door leaves are respectively -2 - articulated around a lower conjugate point pivoting and tilting, and in the open position by pivoting at 90 degrees in the

  extension of the side walls of the body, retract by basement

  same angle in said side walls.

  In order to facilitate this tilting operation, the cross beam of

  upper half of each door leaf is shaped

  circle of center confused with their conjugate inferior point of

and tipping.

  According to a preferred embodiment, each door leaf is

  guided, during its tilting, by sliding of its cross of ex-

  upper trammel in a slide of complementary radius and shape

  reported on each side wall of the body.

  With the aim of allowing a continuous and easy sequence of their

  pivoting and tilting, and vice versa, the ridge of

  upper tremity of the guide rail of each leaf of

  door is slightly set back from the front of the work.

  pouring of upper end of each side wall, and guiding at the start of the tilting stroke and rectifying end of said leaves is ensured by engagement of their upper pivot axis in a groove, formed at this level under said crossbar upper end of each side wall, and also forming

  by its front end shaped as a hinge semicircle superior

  pivoting position for each door leaf.

  Similarly, the front amount of each side wall is reported on the

  internal side to the body of said side walls, and each slide

  is disposed externally to said inner faces so that the products contained in the box can not interfere with the maneuvers of

  tilting and / or straightening of the door leaves.

  Finally, the conjugate lower means of pivoting and tilting of each door leaf is constituted by a vertical clevis mounted

  pivoting on the upper face of one of the elements of the frame of

the said box.

  Thus, by simple means, thus reliable, inexpensive of production and maintenance, and easy handling, access and

  optimum clearance in the open position of the body.

  The understanding of the present invention will be facilitated by the following description of a non-limiting example of a preferred embodiment of such a handling and storage box, with reference to the accompanying drawings in which: - Figure 1 is a perspective view cavalier a handling and storage case according to the invention, whose door leaves are in the closed position; FIG. 2 is a perspective view of the crate of

  handling and storage shown in Figure 1, whose

  door halves are in the intermediate opening position, in the extension of the side walls of the body; FIG. 3 is a perspective view of the crate of

  handling and storage shown in Figure 1, whose

  doors are in the fully open position,

  floor in the side walls of the body; FIG. 4 is an elevational view with torn portions of one of the door leaves of the handling and storage case according to the invention, and of the leader of the second leaf, also illustrating the locking mode in the position of closing said leaves; FIG. 5 is a detail view in elevation of the lower conjugate means of pivoting and tilting of the door leaves

  FIG. 6 is a detail profile view of the inferior conjugate means.

  5 is a detail view in elevation of the connection of a door leaf swing guide guide with

  the upper end cross-member of the corresponding side wall

  dante; FIG. 8 is a bottom view portion, on an enlarged scale, of the connection of the door leaf swing guide slide with the upper end wall of the side wall,

shown in Figure 7.

  As appears more particularly in FIGS. 1, 2 and 3, the handling and storage box essentially consists, in a known manner, of a base frame composed of longitudinal members 1 and cross members 2, coated with a plate of bottom 3, and provided at each of its four angles of vertical uprights 4 and 5 between which substantially extend a rear wall 6 and two side walls 7, in wire mesh, respectively delimited in height by said base frame on the one hand and a cross member 8, 9 upper end of the other. The uprights 4, 5 extend below the underbody frame to act as feet 10 of

  rest for the body, and above the sleepers 8, 9 upper end

  6 of the rear walls and side 7, to be capped at their upper end of the salt cell receiving and support feet 10 of the next higher case in case of storage

  superimposed by stacking. Guide shoes 12 provided with lateral wings

  low height are also transversely

  the sleepers 2 of the base frame to facilitate the handling of

  pulation of the box using forklifts or any other

  appropriate handling equipment.

  In accordance with the object of the present invention, the box of handling

  storage and storage opens with its front face with a double door whose two leaves 13, 14, each consisting of an outer frame trimmed with metal mesh respectively articulated around a lower conjugate point 15 pivoting and tilting, substantially located at the base of the front end of each of the side walls 7, so that in the open position by pivoting forward 90 degrees, in the extension of said side walls 7 , as shown in FIG. 2, said door leaves 13 and 14 retract by tilting an identical angle into these side walls 7, as it appears on

Figure 3.

  In order to facilitate this tilting maneuver, the upper end cross member 16 of each door leaf 13, 14 is shaped as a center circle arc coinciding with their respective lower pivot and tilt conjugate point, and of radius substantially.

  less than the distance between this conjugate point 15 of

  tilting and tilting and the underside 17 of the

  upper mité 9 of each side wall 7.

  At the same time each leaf 13, 14 is guided during its tilting, by sliding of its upper end crosspiece 16 in a slideway 18 of complementary shape and radius and of shaped profile.

  in inverted U, attached to each side wall 7 and coming

  cord with its upper end 19 on the underside 17 of

  each cross-member 9 of the upper end, and by its lower end

  20 on each end crossbar 2 of the underframe.

  In order to allow a continuous and easy sequence of their

  pivoting and tilting rations, and vice versa, as it appears in more detail in FIGS. 7 and 8, the upper end edge 19 of the guiding slide 18 of each door leaf 13, 14 is slightly recessed from the front face 21 of the upper end cross member 9 of each side wall 7, and the

  guidance at the start of the tilting stroke and at the end of

  said flaps 13, 14 is ensured by engagement of their upper pivot axis 22, more particularly visible in FIG. 4, in a groove 23, formed at this level on a part 24 of FIG.

  appropriate form reported on the underside 17 of said / 9 ex-

  upper end of each side wall 7, open at its end

  rear 25 and also forming by its front end 26 in accordance with

  semicircle hinge upper pivoting for each bat-

both 13, 14 door.

  In the same optics, the front posts 5 of the side walls 7 are carried inside the underframe frame and on the inside -6 -

  at the crate of the metal trellising of said side walls

  7, while the slides 18 are arranged externally to the trellis so that the products contained in the box can not interfere with the tilting and / or rectification of the leaves 13,

14.

  As shown in FIGS. 5 and 6, the lower conjugate means of pivoting and tilting of each door leaf 13, 14 is constituted by a vertical yoke 27 between the wings of which is hinged, about a horizontal axis 28 stopped in translation with the aid of external axle brakes 329, by its lower end situated on the upper pivot axis 22, each door leaf 13, 14, said yoke 27 itself being pivotally mounted on the upper face 30 of one of the elements, front spar 1, of the underframe by means of a shaft assembly 31, friction washer 32 and safety nut

33 classic.

  Finally the body is provided with a locking means in the position of

  closing the doors 13, 14 of the door, resting on a stop 34 dis

  placed on the upper face 30 of the front spar 1, and thus constituting

  that it appears more clearly in FIG. 4, by a horizontal bolt 35

  slidably mounted in an appropriate groove 36 of a leaf 13,

  equipped with an operating handle 37 and provided with a groove 38 inclined

  born guiding a control finger 39 secured to a locking rod 40 mounted vertically sliding inside the upright

  41 of the door leaf 13 opposite its pivot axis 22, the ori-

  the guide groove 38 is such that the erection of the bolt causes that of the rod 40 and vice versa the eclipsing of the bolt 35 generates that of said rod 40. In addition, the groove 38 of the bolt 35 has at its upper end. a slight horizontal range 42 so that in the unlocked position of the assembly the weight of the vertical rod 40 does not cause by gravity the inadvertent erection of said

rod 40 and bolt 35.

  The scope of the present invention is not limited to the embodiment described above but can be extended to all variants of execution, so among others, that the side walls of the body may well be made of double-walled caissons, between which the door leaves will be retracted

in the extreme open position.
