    Lightweight supermarket trolley. The invention relates to a supermarket trolley for transporting products sold therein.
    More specifically, it is a carriage comprising: - a support structure, which comprises an erected rear portion provided with a guide handle and suspension means for suspending a storage support, the rear portion erected s' raising from the rear of a lower base to which it is fixedly attached, therefore without the possibility of tilting relative to it, the lower leg being provided with wheels and advancing, substantially horizontally, in a tapered shape reserving a empty central space, extending rearwardly under the rear part, to allow the engagement of the ejffilée form of a second carriage identical to the latter in the empty space of the latter, for a compact storage, - A first and a second latch elements, one provided on the first carriage being reversibly lockable with the other provided on the second carriage. EP 1 403 164 describes many of these features.
    A problem remains with the realization of a supermarket trolley (which can also be called a shopping trolley): - which allows to classify products put, or to put, in the trolley, - which facilitates their handling, by example at the time of the checkout or when they are transferred for example into the trunk of a vehicle, - which is easily built-in, or engageable, at least 40% of its length in the operating state. loading, in another identical placed in front, - which remains compact to circulate in alleys and crates of a small supermarket, or superette, district.
    A corollary problem concerns the ability for the user to be able to leave the supermarket with the products, or provisions, purchased, without having to load those (these) in a different provision support. 'r
    To overcome at least some of these problems, including the corollary problem, it is proposed that the suspension means are arranged on a bar, movable on the rear portion erected between: - a carrying position in which it defines a bracket with the rear part erected, allowed to suspend bags (as a support for provisions), and which, from this rear part, advances in an area above said lower base, - and a retracted position to the away from said area, to allow said engagement of the second carriage therein.
    In particular, a bracket makes it possible to replace a bulk loading of the products in the traditional bins or vats of known carriages by a loading support where the hanging bags make it possible to classify the products, and which can be less heavy to handle than when it is necessary to take the products out of the tank or basket, for example at the checkout counter. With respect to EP 1 403 164, the above solution avoids the store having to manage the storage of the removable baskets provided. .
    For compact storage and ease of realization of the trolley and use for the customer, it is recommended that the bar is rotatably mounted on the rear portion, between the porting and retracted positions.
    In order to increase the compactness and / or to keep the bar in the retracted position, it is advisable for the upright rear part to have a slot located above the bar, in the position of being carried, and where the bar penetrates when it is in position. retracted.
    To prevent the bar from moving from its retracted position to its carrying position, it is proposed that: - the bar comprises at least one hook adapted to suspend at least one shopping bag, and, - that the width of the slot and the size of the hook are such that in the retracted position the bar is retained in the slot by forced engagement of the hook in this slot. Complementarily possible, useful for ease of manual operation by the user, it is proposed: - in the carrying position, the bar has a lower face where is located a handle of maneuver this bar and, - that the slot receive at least one said hook, but not the handle, in the retracted position of the bar.
    The handle is thus always easily accessible.
    On the other hand, to limit the human intervention while favoring the compactness of the storage of an unused trolley, it is advised that the erected rear part be such that its rear face is provided with an abutment against which abuts the bar of the second carriage, in the carrying position, or immediately close to it.
    For the same reasons, it is advisable that: - in the carrying position, the bar advances by being inclined upwardly, and / or - the abutment comprises a sloping portion with respect to the horizontal and vertical.
    In the context of a molded plastic construction, solid and economical, it is advised that the rear erected part understands: - a lower one-piece element with at least a portion of the base and which stands from it, - an intermediate element booster in the form of an erected beam, and j - an upper guiding and carrying element engaged with the lower element, in the upper part thereof, and fixed to it, this upper element comprising the guide handle and the bar provided with said suspension means.
    Yet another aspect relates to the ease of use of the cart with different types of bags. It is therefore proposed that, preferably, the arm comprises additional suspension means adapted to suspend undecided bags and comprising elongated blocks along the arm and erected to retain handles of a passing bag (crocheted) behind . '
    A more detailed description is given below, with reference to the drawings in which: FIGS. 1, 2, 3, 6, 7, a first embodiment of a trolley, FIG. 5, two such trolleys, one behind the other, adjacent and recessed, - figures 4.8, two embodiments, in particular respectively of the support part of the heavy loads and the up rear part, - Figure 9, a dedicated bag (specific), with a detail figure 10, - Figures 11,12, the arm comprises, in addition to the suspension means dedicated to a specific bag / s, additional suspension means can receive a / non dedicated bags. Figure 11 is the following view XI of Figure 12 which is a side view of the bar.
    In different figures, we therefore see at least one carriage 1 comprising a support structure 3.
    The support structure 3, or structural frame, comprises a rear portion 5a erected and a base 5b below which this part is fixedly connected, therefore without the possibility of tilting with respect thereto. The rear portion 5a rises from the rear of the base 5b. The rear portion 5a is provided with a guide handle 7 and suspension means 9 for suspending (at least) a storage support 11. The base 5b is provided with wheels, such as 13a, 13b, 13c, and s' advance, substantially horizontally, in a tapered shape 50b. The tapered shape 50b, reserves an empty central space 14, which it thus surrounds, and extends rearwardly (AR; FIG. 2) to below the rear portion 5a, to allow the engagement of the tapered shape 50b ' a second carriage 1 'identical to this one in the empty space 14 of the latter (Figure 5).
    The suspension means 9 are arranged on a bar 15 which is mounted movably on the upstanding rear part 5a, between: - a carrying position (FIGS. 1, 6, 6, 8) in which it defines a bracket with the rear part 5a ; which makes it possible to suspend shopping bags, such as 17a, 17b, and another position (Figs.3,5) where it is retracted, to then allow said engagement of the second carriage 1 * in the carriage 1, as shown in fig.5.
    In the carrying position, the wedge 15 projects from the rear part 5a into an area 19 situated above the base 5b. In the retracted position, it is away from this area 19.
    As indicated above, the bar 15 is therefore cantilevered on the front of this rear upstanding portion 5a, which frees up space and facilitates the interlocking of the carriages in the stored state, in the store or on his first
    In the illustrations, the bar 15 is, as preferred, movably mounted in rotation on the rear portion 5a, between the carrying and retracted positions. The axis of rotation, here horizontal, is marked 150.
    Figures 1-4, we see that to promote the maintenance <of the bar in the retracted position, which can facilitate the recessed storage operation of the carriages (Figure 5), the upright rear portion has a slot 21 located (substantially in its vertical) above the bar 15, when in the carrying position, and where this bar can penetrate when it is in the retracted position (Figures 3, 5).
    In addition, in order to prevent the bar 15 from moving from its retracted position to its carrying position, FIG. 6 shows that: the bar 15 comprises, as suspension means 9, at least one hook 90 for suspending a shopping bag, such as those mentioned above 17a, 17b, and - that the width 11. of the slot 21 and the lateral space of the hook concerned are such that in the retracted position the bar 15 is retained in the slot 21 by forced engagement of the hook in this slot. Figure 3, it is the double hook 90a 'fle closer to the free end of the bar.
    If it is desired to facilitate manipulation of the arm by the user, a handle 23 is provided on the lower face 15a of the bar 15, the latter then being assumed in the carrying position. In addition, in the retracted position of this bar, it is preferable that the slot 21 receives at least one of the aforementioned hooks, but not the handle 23 which will remain fully hand-grip, front end of the carriage.
    To limit the intervention of the user, while promoting a compact storage, it is advisable on the other hand that the erected rear portion 5a is such that its rear face 50a2 (which is located opposite a front face 50al oriented forwardly of the lower leg 5b) is provided with a stop 25 against which stops the bar 15 'of the second carriage 1', in the carrying position, or immediately close to it.
    The stop 25 then promotes a movement of the bar towards its retracted position, if necessary by guiding it.
    When the user pushes the second carriage 1 'to the first 1, to store it, the bar 15' of the second carriage will be in the carrying position, or immediately close to it in the sense that, for example if the bar linkage / rear portion 5a erected occurs between plastic and metal, the withdrawal of bags 11a, 11b ... (Figure 6) out of the gallows will have more move this bar.
    An inclination of the bar 15, in the carrying position, as it advances by being inclined upwards may be considered also useful for both storage and porting.
    Another solution: that the abutment * 25 comprises a pan 25a inclined relative to the horizontal and vertical. An inclination towards the front and the top is recommended, as shown; 45 ° or more can be favorable.
    To make the guidance even more effective with a compact solution, the stop can, as illustrated,
    , I present, as Figure 7, a groove 250 curved upward and forward. Figure 2, the stop is projecting backwards. The groove is preferable: guiding more effective and less likely to be damaged.
    As mentioned before in the description, a problem addressed here also relates to the · way of guiding the trolley efficiently in small spaces.
    For this purpose, the guide handle 7 has a width 1_3 greater than that h4 of the rear portion 5a at least at or close to its upper end, or even over its entire height, this in a direction Y transverse to the direction X along which advances the base 5b and to which the handle 7 is linked, preferably by fixing.
    To secure / make reliable the realization and the mechanical strength in the time of the carriage, as well as. its capacity to support rather heavy loads (packs of water, milk ...), if possible with a large compactness of (inter) commitment ranged trolleys and a good stability in their displacements, one sees in particular figures 1, 2, 6, 8 that, in this preferred embodiment, the tapered shape 50b defines a frame which borders laterally and at the front the empty central space 14.
    In this embodiment, the stable profile of the carriage is also provided with an upright rear portion 5a which has in the lower portion 51a an arch form 501a having two lateral legs 503a, 505a erected on either side of a central opening 507. The lateral legs are connected, at the front, to two bars 503b, 505b of the tapered shape which extend laterally, on either side of the central space 14, which communicates with the rearward with the opening 507, for the engagement of the second carriage 1 'in the first 1. At the front, the two bars 503b, 505b converge to a profiled front block 513b, higher than they, but less than 507 opening.
    It is also advantageously provided, in this preferred version, that in the lower part 51a the upright rear portion 5a has two lateral flanks 509a, 511a where the erected rear portion widens and the carriage comprises straps 31 extending across the central space 14. '
    These straps 31 are attached, at the rear, to (for example around) the sidewalls 509a, 511a and, preferably, at least further forward, to the lower leg 5b, for example to the tapered shape, as illustrated. .
    It can be bands, wide, flexible or for example a net structure.
    It is recommended that these straps be loose enough to be pushed upward away from the space 13 when the tapered shape or the base 5b 'of the second carriage engages in the central space 14 of the first carriage. However, it is seen fig.5, that during a recess, the front block 513b of the rear carriage can be locked in the straps duf: forward carriage, by a transverse branch 31a thereof.
    Alternatively, as shown in FIG. 4, if rigidity is preferred, it is provided that in the lower part the carriage may comprise a (rigid) floor 33 pivotally mounted on the upright rear portion 5a or the lower leg 5b in order to be pivotable to away from the central space. 4, the horizontal axis 330 is located at the top of the angle floor 33.
    To secure the mechanical strength of the stem under load, in a manner compatible with a possible plastic molded manufacture of the structure 5a, 5b of the carriage, it is proposed that the rear upright portion 5a is provided under the bar 15 and on its face. before 50al, a shoulder 35 on which the bar rests, near its pivot axis 150, in the carrying position (Figures 1, 2, 8). - In the same context of a solid and economical molded production, it is recommended, as illustrated, that the up rear portion 5a comprises: - a lower element 521a monobloc with at least a portion of the base 5b (here all this base) and which · Stands therefrom, and - an upper element 523a for guiding and carrying engaged with the lower element 521a, in the upper part thereof, and attached thereto.
    In the preferred embodiment illustrated in FIGS. 6, 7, the upper element 523a comprises the guide handle 7 and the bar 15 provided with said suspension means 9.
    In a complementary manner, it is preferred, in this preferred version, that the lower element 521a may have the aforementioned arch shape 501a favorable to the mechanical strength and the displacement stability of the carriage.
    8, the central vertical bar 521al of the inverted "Y" formed by the monobloc lower element 521a has an upper opening 530 in which a vertical element 531a standing between 521a and 523a and belonging to the part 5a is vertically engaged. The beam-shaped intermediate element 531a is provided with the bar 15, with its support 35 and may comprise a part of the slot 21. An upper opening 533 makes it possible to vertically engage the upper element 523a, via a central base 533 in the form of a beam that this one presents here. Figure 8, we also see different useful construction details, such as the two vertical tie rods 24 which cross interior passages of the erected portion 5a to connect them vertically, the elements 521a, 531a and 523a, by screwing.
    1, 2, 3 in particular, the upper part 523a carries the handle 7 and the bar 15. An element
    Intermediate 535a beam-shaped, without bar 15, used as booster, and fixed as above, can be interposed. This allows a reduction in costs and manufacturing difficulties by molding, plastic. And we limit the most technical design to the top 523a.
    Another possibility: the erected elements 521a, 523a are directly engaged one inside the other and fixed together, as described above (FIG. 7).
    Figure 9, we see in more detail one (11a) of the aforementioned shopping bags 11a, 11b. 'R
    This bag comprises: - a side wall 54 surrounding the upper edge 540 an opening 53 through which the bag can be filled and emptied, - 51.58 suspension means of the bag to hang indifferently by hand or a carriage 1 to provisions attached to a supermarket, as shown in Figures 2, 6.
    The bag has a capacity of less than 0.040m3 (weight limit for the user), and preferably between 0.015m3 and 0.035m3.
    Preferably, the bag suspension means 51, 58 comprise: handgrips 58 connected to the side wall 54 and adapted to suspend the bag by hand, and complementary suspension means 51 of the bag for hanging it on the carriage. Preferably, the complementary suspension means 51 comprise a horizontal slot 101, or two horizontally spaced eyelets 51a, 51b. These can be located near the upper edge 540 of the side wall 54. It is advisable that these means 51 are located on one side of the wall 54 of the bag, as shown; this ensures a foolproofness. .
    Preferably, the bag will comprise elastically deformable means 55 connected to the side wall 54 of the bag and located towards the opening 53 to naturally request this opening to an open state to fill it.
    Advantageously, these biasing means 55 will comprise curvable rods 551, 553. They will preferably be disjoint at two opposite ends 54a, 54b of the side wall 54 to facilitate flattening of the bag, with closure of its opening 53.
    Figure 9, as preferred: - The sticks 551, 553, flexible, are naturally rectiligne, and the side wall 54 comprises two panels 54 ^, 543 joined together at said two opposite ends 54a, 54b of the side wall by flexible connections, such as seams 65, rising on the height of the panels, for the flattening of the bag.
    Still advantageously, at the two opposite ends 54a, 54b, the side wall 54 comprises articulated lateral flaps 690, 691 and is provided with tabs 70, 71 for operating the lateral flaps 690, 691.
    The mark 58 shows the two handles attached to the wall 54, the bag is preferably provided.
    To promote the opening of the top of the bag (53), it is also recommended that the bag has a bottom 93 flexible (as wall 54), but stiffened by a plate 96 foldable or folding.
    Tilted flat at the bottom of the bag, the plate 96 promotes the opening of the bag at the top, in 53.,
    Moreover, as illustrated in particular in FIGS. 2, 6, on the assembly comprising the shopping bags 11, 11a, 11b and the carriage 1, it can be seen that the bar 15 is thus provided, as suspension means 9, with the hooks 90 located in pairs on or near the opposite longitudinal side edges of the bar. At least one of the bags is suspended laterally, on each side of the bracket 15, by at least two eyelets 51a, 51b. From the figures, it is understood that: - hanging bags, the eyelets 51a, 51b are located at the same level, on the same side of each bag, - and, bags extended flat as Figures 2 and 9, the distance di between these two eyelets is equal to that d2 separating two successive hooks located on the same side, along the bar. . ·
    FIGS. 11, 12 show that the / each suspension arm comprises (may include), in addition to the suspension means 9, 90a ..., dedicated to adapted bags (here suspension by hooking, via means 51 of the bag). , additional suspension means 105 that can receive non-dedicated bags.
    Favorably, these additional suspension means will include an elongated block (s) 107 located along the upright flanged suspension arm (s) adapted to retain the or the handles 58 or 580 of a bag (the / the handles will pass (have) behind). '
    Preferably, the (each) additional suspension means 105, 107 will be located in the longitudinal alignment of the hooks (parallel to the axis 115 of the bar 15) in order not to interfere with the embedding or the suspension / removal of the bags. These bags will continue, to be able to be so suspended, on two sides, back to back.
    Preferably, to promote stabilization of each hanging bag, stretching it longitudinally, so to speak, while placing it thus at a height favorable to its filling and maneuvering (placement / withdrawal vis-à-vis the bar 15 ), each additional suspension means 105, or block 107, with a length L5 of the arm of between 10 cm and 30 cm, along the arm 15 (axis 1 5), will be realized; advantageously between 10 cm and 20 cm approximately, and / or a spacing d2 (axis 115) between two successive suspension elements 90a, 90b- between 10 cm and 40 cm; advantageously between 15 cm and 25 cm or 30 cm approximately. Note again, Figures 6.7, that are provided on each carriage, a first and a second latch elements 110a, 110b, for reversible locking between two carriages such 1.1 '. One of these latch elements, provided on the first carriage 1 is thus lockable with the other provided on the second carriage 1 '.
    FIG. 12 also shows that the front lower free end portion (AVT) of the bar 15 is angled, at 15a, with respect to the horizontal and the vertical so as to favor an upward inclination of the bar then in position " stem "when it will abut against the stop 25 of the front carriage, in a recessed storage.
