Description

"Articulation piece, especially for intermediate partition of a carriage

  The present invention relates to a hinge part, allowing in particular but not exclusively, to ensure the connection between a wall of the basket of a self-service shopping trolley and a transverse partition intended to be mounted inside

of such a basket.

  It is known that the carts of such stores are usually constituted by a large transport basket, located at a certain height with respect to a lower base on which wheels are fixed, an operating handle being provided at the upper part of the end. back of the set. Usually, the basket is bounded by a bottom and four sides, and has a wide open top for loading and placing objects in the cart.

  or goods that the consumer wishes to acquire.

  However, for certain applications and specific uses

  cart, it may be advantageous to have in the

  basket a transverse partition, delimiting a box

  possibly closed by a folding lid and intended to contain the bag or other similar accessory of the consumer during his movements inside the store during which he makes the choice of

items he wants to buy.

  For this purpose, the transverse intermediate partition must be connected to the lateral sides of the basket by articulated connecting members such that, once the partition is in place, it can no longer be removed, thereby preventing a third party from accessing inside the

  housing when the lid is folded down.

  The present invention relates to an articulation of this kind that meets the purpose thus specified and whose very simple design allows it, once mounted on the partition to articulate, to be inviolable, that is to say that it can not to be dismantled in order to avoid any attempt of fraud or theft of an object placed in the

closed housing.

  For this purpose, the joint considered is characterized

  in that it comprises two hollow half-shells facing each other and each comprising two elongated lateral sliding rails, adapted to cooperate

  mutually by sliding with the slide rails

  shells comprising two first hemi-cylindrical recesses

  These recesses delimit between the shells two passages, each capable of being traversed by a rod, on which the articulation is pivotally arranged, and in that one of the half shells comprises, at the right of each of its two slides. , a flexible tongue whose elasticity, without preventing the relative sliding of the interlocking slides of the two shells, causes

  Advantageously, the two half-shells comprise

  stretching to the direction of the first two recesses hemi

  cylindrical and in such a way that these third

  FIG. 6 is an illus-

  Figures 1 and 2, reference 1 schematically denotes

  transport for a self-service store of a type in itself

  even well known in the art. This basket is constituted in its lateral sides and its bottom by means of a wire mesh formed of rigid metal son, respectively 3 and 4, extending in two directions

  generally perpendicular, and present in its

  upper part, a fully open face to allow

  loading inside the basket of

  To carry, the outline of this upper surface

  being defined by a belt 5 in which

  end the ends of the wires 3.

  In particular to delimit within the

  basket 2 a suitable housing, it has in

  ci an intermediate partition 6, also consisting of a metal frame 7 surrounding a mesh part of

  metallic threads 8, similar to those used for

  kill the basket 2 itself. This intermediate partition 6 comprises, at its lower end, a hook 9, engaging on one of the wire of the bottom mesh of the basket, and is also joined to the lateral sides thereof by means of one or even several pieces of articulation 10 according to the invention, these parts being designed so that once put in place, they are inviolable, that is to say can not be removed, thereby prohibiting the removal of the intermediate partition 6 and therefore the access to the housing delimited by this partition if it is closed by a

  folded lid attached to the partition and the corresponding sides

of the basket.

  As can be seen more particularly in FIGS. 3 to 5, each hinge part 10 is constituted

  killed by means of two half-shells, respectively

  FIGS. 11 (FIG. 3) and 12 (FIG. 4), these two half-shells 11 and 12 both having an identical external profile. Each of these half

  shells has on both sides of its central part

  trale two parallel internal slides, respectively

  13 and 14, able to interlock each other during the sliding

  the two half-shells in the manner more particularly shown diagrammatically in FIG. 6. For this purpose, each slide has a protruding shoulder 15 and a hollow return 16, designed to respectively engage one of the two half-shells. in the other, from a slide to that which cooperates with it in the two half shells placed in contact with each other. In addition, one of the two half shells, for example the shell 12, has the right of each of its two slides 14 and substantially

  in their middle part, a resilient 17 tongue

  misaligned towards the inside of the half-shell, this tongue 17 being intended to engage in a recess 18 formed in the slide opposite the other half-shell, once the latter engaged

  one on the first and brought into a covering position

completely.

  Figure 6 gives a better view of how

  kills the assembly of the two half shells 11 and 12 one on

  the other, as a result of the mutual commitment of their

  13 and 14 allowing their relative sliding. During this movement the tongue 17 of each slide 14 is first constrained by the shoulder 15 opposite the slide 13 to be placed in the extension of the slide 14, until the two half-shells overlap completely, where the tongue 17 can then escape inwards by penetrating into the hollow 18 of the other half shell. As a result, in this position, the two half-shells 11 and 12 are locked with each other, their release by a displacement in the opposite direction of the two slides for example being made impossible, because of the commitment of the tab 17

in the hollow 16.

  Each of the half-shells 11 and 12 or, where appropriate, only one of them, as illustrated on

  Figure 6, has two first transverse recesses

  hemi cylindrical, respectively 19 and 20 open and

  extending perpendicular to the direction of the

  13 and 14, so that when these two shells are applied to one another in a position of

  cover, these recesses 19 and 20 are closed.

  sideways while allowing the passage through them, firstly on one side of a wire 3 of one side of the basket 2 and secondly the outer belt 7 of the partition 6 , realizing between these two

  elements the desired articulation.

  Each joint 10 thus ensures the connection between the basket and the intermediate partition, without this joint once mounted, can be removed,

  by finally solidifying the partition.

  Each joint made by means of two half-shells 11 and 12, has the particular feature of allowing a slight deflection of the partition 6 to

  the front or the back of the basket thanks to the free

  wise through the recesses 19 and 20 of a vertical wire 3 of the mesh forming the corresponding side of the basket, and the belt 7, such clearance being particularly necessary when the upper part of this

  partition carries a lid (not shown) for it

  to either come and lean against that wall, or

  to be first raised and then folded over the front part.

  2. Advantageously, each of the preceding half-shells 11 and 12 comprises a third recess 21, the direction of which extends transversely relative to that of the first recesses 19 and 20, leaving an open transverse passage in which engages one of the horizontal son 4 of the basket 2, thus allowing to properly wedge height of the hinge part 10

compared to the partition.

  Finally, the piece 10 may also comprise in the two half-shells 11 and 12, possibly in one of them, for example in the single half-shell 12 as shown in FIG.

  recess 22 formed opposite the recess 21, allowing

  so also to engage in the joint one of the threads

  8 of the partition 6, as illustrated schematically

in Figure 2.

  Thus a tamper-resistant hinge design very simple, particularly well suited to mounting on the basket of a trolley for self-service store; however, it goes without saying that the invention would apply equally well to any other device comprising a mesh wall and that one would wish to compartmentalize. Similarly, it should be understood that the invention does not prejudge the nature of the materials used to make the shells may consist of metal or plastic parts, or even composite with a metal body and slides with the elastic tongue in one plastic material

  having adequate elasticity.
