Description

Shopping trolley with removable bags

The invention relates to a shopping trolley of the kind intended to be equipped with removable bags.

The object of the invention is to provide a carriage with a very simple structure capable of receiving bags of various types without the bag catching devices constituting an obstacle to the interlocking of the carriages between them and in which the placing and removal of the bags is easy for the user.

For this purpose, the subject of the invention is a shopping trolley with removable bags of the type comprising a rearwardly open rolling chassis which comprises two horizontal spars diverging towards the rear and joined together by a front cross member, said spars carrying at their rear end two uprights rising in height at the upper end of which are mounted gripping means for users, such as handles or a bar maneuver.

According to the invention, the frame carries a plurality of transverse bag support rods disposed above the horizontal plane defined by the longitudinal members at increasing heights from front to rear and dividing the carriage frame into open cells on at least one of the sides, relative to the normal direction of travel of the carriage, said transverse bars being fixed by a connecting means positioned vertically at least one of said horizontal spars, and said transverse bars are provided with means for the hanging of removable bags.

The rear-facing trapezoidal chassis allows multiple carriages to nest into each other for storage in storage yards waiting to be used by customers. The arrangement of transverse bars carrying stacked bags one behind the other in the longitudinal direction at increasing height levels from the front (corresponding to the short side of the trapezium) towards the rear (corresponding to the long side) provides a great simplicity of construction, and ease of loading and unloading bags by the users, without the sleepers and the means of attachment of the bags they wear can not interfere with the interlocking of the trolleys and / or their disengagement. The transverse bars divide the template defined by the frame of the carriage in open cells on at least one of the sides which make it much easier to handle the bags both empty and full, especially when they are transferred into the vehicles of the users.

In addition, the transverse bars are fixed on the frame of the carriage and are not part of a removable bag adapted to be received by the carriage, which allows to use different types of bags.

The invention is further characterized by the following features:

the cells are more particularly each open on at least one of the sides which is contained in a vertical plane containing one of the longitudinal members.

at least two successive transverse bars in combination with at least one connecting means delimit a hexahedron-shaped cell of which at least three of the sides are open (for example the upper, lateral and transverse sides).

- The transverse bars are fixed at least on one side to a wall disposed in line with one of the frame rails; alternatively, said wall is carried by a frame spar;

- Alternatively, the transverse bars are connected at least on one side to a rear upright of the frame;

- Alternatively, the transverse bars are fixed at least on one side to a bracket arranged at the rear end of a spar, the arm of said stem extending forwardly and downwardly parallel to said spar;

alternatively, the transverse bars are each fixed on a vertical pillar carried by a chassis spar;

- Alternatively, the attachment point of the pillar of the front crossbar on the spar is offset rearwardly relative to the vertical plane of delimitation of said bar;

- Alternatively, the pillar of the front crossbar is fixed at the bottom of the pillar of the adjacent transverse bar, for example in the lower part of the pillar of the second cross; - In turn, the intermediate transverse bars are each carried by a pillar fixed to a chassis spar and the front crossbar is carried by two pillars fixed to the front cross member connecting the longitudinal members of the frame;

alternatively, the transverse bars are each carried by a pillar fixed to a chassis spar and the chassis comprises, near its front part, an auxiliary vertical pillar carried by the spar opposite to that carrying the pillars of the transverse bars;

alternatively, the transverse bars are each carried by two vertical pillars fixed on the two longitudinal members of the chassis;

- The transverse bars are interconnected by spacers;

the spacers form a continuous belt extending from one of the rear uprights of the chassis to the front cross member;

- The chassis is provided in the lower part of a loading platform extending rearward substantially to the level of vertical uprights;

alternatively, the platform is fixedly mounted on the chassis, and extends backwards and upwards from the nesting limit, its lateral edges converging towards one another;

the platform is provided on one of its longitudinal sides with a vertical wall;

the platform is connected to the pillar of the second transverse bar from the front of the carriage by a tie rod fixed to the rear end of said platform;

the hooking means of the bags comprise pieces in the form of a double hook, one of the hooks being disposed above and the other hook being placed below the transverse bar which carries them;

In all the embodiments described hereinafter, the carriage according to the invention comprises, in a manner known per se, a trapezoidal rolling chassis open towards the rear.

This rolling chassis comprises among others:

two longitudinal members (1) diverging towards the rear,

a front cross member (2) joining together said longitudinal members (1),

- two vertical uprights (3) rising in height and which are connected to said longitudinal members (1),

gripping means (4) mounted on the upper ends of said uprights (3).

a plurality of bag support crossbars (10a-10d) disposed above the horizontal plane defined by the chassis side members (1) at increasing heights from front to rear and dividing the carriage frame into cells (A cavity is understood to mean a space or an open space delimited by the aforementioned elements and which is for example suitable for receiving a removable bag) open on at least one of the sides, connecting means (3, 11; 3, 13; 3, 14a-14c) positioned vertically of at least one of said horizontal longitudinal members (1) and on which said transverse bars (10a-10d) are fixed,

means (12, 20, 21, 22) for attaching removable bags (S) arranged on the transverse bars (10a - 10d).

Each spar (1) has a rear end connected to a vertical upright (3) whose upper portion extends obliquely rearward, said upper portion comprises gripping means (4) such as a barbell .

More particularly, the maneuvering bar (4) interconnects the free ends of the uprights (3) by means of assembly parts (5).

Under the frame, near the front cross member (2) is fixed a transverse plate (6) on which are mounted two front direction wheels (7).

Under the upright rear uprights (3) are fixed two rear directional wheels (8).

An opening is delimited on the rear face of the carriage by the uprights (3) in combination with at least one transverse bar (10d) so as to allow the interlocking of two carriages therebetween.

Behind the plate (6) for mounting the front casters (7), the frame advantageously comprises an auxiliary crossbar (9), which, in addition to its function of reinforcing the frame, forms a stop interlocking two trolleys between them.

Furthermore, each of the transverse bars (10a-10d) extends, in projection on the plane defined by the longitudinal members (1), in an orientation substantially perpendicular to the horizontal longitudinal members of the chassis of the carriage and for example of a spar to a other.

In addition, the cells are more particularly open each on at least one of the sides which is contained in a vertical plane containing one of the longitudinal members (1). These vertical planes are therefore substantially perpendicular to a horizontal plane containing the two longitudinal members (1). In addition, at least two successive transverse bars (10a-10d) in combination with at least one connecting means (3, 11; 3, 13; 3, 14a-14c) delimit a hexahedron-shaped cell of which at least three sides are open.

In the exemplary embodiment shown in FIG. 1a, it can be seen that, from the front cross member (2) to the rear posts (3), the carriage has four transverse bars (10a, 10b, 10c, 10d) arranged in height of stepped manner increasing from front to rear, said transverse bars being regularly spaced apart over the length of the frame. For the rest of this description, the front cross bar (10a) will be called the first bar and the following will be designated by their chronological order from this first bar. In this embodiment, the first three transverse bars (10a-10c) are carried by a vertical wall (11) fixed on a spar (1), while the fourth (10d) is carried by the rear struts (3) of the frame. In the example shown, the support wall (11) of the transverse bars (10a, 10b, 10c) is inverted L-shaped and its base extends only over a small part of the spar (1) on which it is fixed. Alternatively, the wall (11) could be formed of a plate extending over the entire length of the frame, the outer face of the wall thus constituting a large area available for the communication of the store equipped with such trolleys.

We see that the transverse bars (10a, 10b, 10c, 10d) and the wall (11) which carries three of them delimit three cells, open laterally on one side of the carriage, inside which will be housed removable bags open upward hung on attachment means fixed on transverse bars (10a, 10b, 10c, 10d). We also see that the combination of the first three transverse bars (10a, 10b, 10c) with the wall (11) which carries them defines brackets whose height and width increases from front to rear. The vertical distance between two consecutive transverse bars is calculated so that the hooking means of the bags carried by the transverse bars can not be obstacles to the interlocking of the carriages with each other. In the embodiment shown in FIG. 1a, the hooking means of the bags comprise double hook-shaped pieces (12), one of the hooks being arranged above and the other hook being arranged on top of each other. below the crossbar that carries them. These hooks are intended to cooperate with hooking slots arranged on the corresponding faces of a removable bag as shown in Figure 6. It shows that the vertical offset between two successive transverse bars combined with this arrangement of double hooks offset in height makes it possible to present the bags in a vertical position without the bag of one cavity being able to assume an oblique position encroaching on the adjacent cell or causing it to strike a bag possibly disposed in the adjacent cell and / or the content of the latter. This arrangement therefore provides an increased ease of handling of the bags both when they are placed on the truck and when they are filled and removed during the checkout and / or transfer to the user's vehicle. In addition, it provides security against the risk of damage to fragile goods placed in a bag as a result of clashes with the contents of another bag disposed in an adjacent cell.

In the variant embodiment shown in FIG. 1b, the wall (11) has been replaced by a bracket (13) fixed on the rear end of a spar (1) and whose arm (13 ') extends towards the bottom parallel to said spar.

In the embodiment shown in Figure 1c, the connecting means of the first three transverse bars (10a, 10b, 10c) comprise pillars (14a, 14b, 14c) which rise above the frame. The pillar (14a) of the first transverse bar is fixed on the connecting beam (2) between the front ends of the two longitudinal members (1) and the support pillars (14b, 14c) of the two other transverse bars (10b, 10c) are fixed on one of the two longitudinal members (1). The pillar (14b) of the second transverse bar (10b) is arranged near the auxiliary crossbar (9).

The carriage shown in Figure 1d is an alternative embodiment of the carriage of Figure 1a. In this embodiment the point of attachment of the pillar (14a) of the first transverse bar (10a) is offset rearwardly with respect to the vertical delimitation plane of said transverse bar (10a). This arrangement provides the advantage greater insertion width when nesting two carriages together, which facilitates the nesting operation requiring less attention and precision from the user in driving the carriage. In addition, when the carriage is equipped with a platform, as represented for example in FIGS. 3a to 3c and 7 to 11b, this arrangement makes it possible to widen the front part of the platform by extending it laterally to the level of the side members. along the length extending between the front edge [or the front cross member (2)] and the pillar 14a.

According to another variant embodiment shown in FIG. 1c, the same advantage is obtained and amplified by the fact that the pillar (14a) of the front transverse bar (10a) is fixed at the bottom of the pillar (14b) of the second bar. transverse section (10b) by a horizontal segment (14a ').

Figure 1f further illustrates another alternative embodiment of a carriage similar to those shown in Figures 1c, 1d and 1c. In this variant, the first transverse bar (10a) is connected to the frame by two pillars (14a) fixed to the front cross member (2) of the frame. This arrangement provides the advantage of being in the delimiting plane before a protective frame in possible collisions with furniture, people or other obstacles during the use of the carriage.

Figure 2a shows an alternative embodiment of a carriage according to the invention. In this embodiment, the first three transverse bars (10a, 10b, 10c) are each connected to the frame by two pillars (14a, 14b, 14c). As in the example of FIG. 1f, the two pillars (14a) of the front transverse bar (10a) are fixed to the front crossbar (2), while the pillars (14b, 14c) of the two following crosspieces (10b, 10c) are fixed to the two longitudinal members (1) of the frame.

Figure 2b illustrates an alternative embodiment of the carriage of Figure 2a in which there are arranged spacers (15a, 15b, 15c) interconnecting two successive transverse bars. In this embodiment, the spacers (15a, 15b, 15c) are not directly connected to the ends of the transverse bars (10a, 10b, 10c) but between the pillars (14a, 14b, 14c) and the rear pillar (3). who wears them. We see in this example three spacers arranged alternately on one side and the other of the carriage. More precisely and considered in relation to the direction of normal movement of the carriage, a first spacer (15a) connects the left front pillar (14a) of the first transverse bar (10a) to the left front pillar (14b) of the second transverse bar (10b), a second spacer (15b) connects the pillar right (14b) of the second crossbar (10b) to the right pillar (14c) of the third crossbar (10c) and a third spacer (15c) connects the left pillar (14c) of the third crossbar (10c) to the post rear left (3) of the chassis. The purpose of the spacers (15a, 15b, 15c) is to reinforce the strength of the pillars and to prevent their deformation or buckling under the effect of the constraints and mistreatment that the shopping carts are generally subjected to. They also provide the advantage, in combination with a platform that will be described in more detail later, to provide bulky package retention means in the cells that are not occupied by removable bags which greatly increases the applications. of the carriage according to the invention.

Figure 2c illustrates another arrangement of the spacers in combination with a carriage of the same type as that of Figure 1c. It can be seen that instead of being arranged discontinuously on both sides of the transverse bars and / or the pillars carrying them, the spacers are arranged on the ends of the transverse bars (10a, 10b, 10c) and connected to each other. to a rear upright (3) of the frame so as to form a continuous belt (16) between said upright (3) and the first transverse bar (10a).

Figure 2d shows a carriage identical to that of Figure 2c on which is mounted at the bottom a loading platform (17). In a manner known per se, this platform can be rotatably mounted about a horizontal axis disposed near its front end so as to be able to lift when two carriages interlock with one another. In such a case, the platform will preferably have a trapezoidal contour making maximum use of the available area defined by the longitudinal members, the cross member and the frame uprights, at least on the side which is not provided with pillars in the embodiments of the trolleys in which the transverse bars are supported only on one side of the trolley. The platform (17) can be made as a plate or as a grid, as seen for example in Figure 5. Figures 3a, 3b and 3c illustrate a preferred embodiment of a loading platform on a carriage of Figure 2d. The platform (17) is fixedly mounted on the chassis. It is for example welded to the front cross member (2) and extends obliquely rearwardly and upwardly so that at the nesting limit materialized by the auxiliary beam (9) it is sufficiently spaced in height not to come into contact with the front cross member (2) of the sliding carriage.

The platform (17) is provided on one of its longitudinal sides with a vertical wall (18). To ensure that the plate forming the platform (17) can not deform to the point of making nesting impossible, its rear end is connected by a tie rod (19) to the pillar (14b) of the second crossbar (10b).

Figures 4a, 4b and 4c illustrate an alternative embodiment of the bag hooking means on the stepped transverse bars of a carriage according to the invention. In this example these alternative means are fitted on a carriage of the same type as that of Figure 2a, that is to say in which the transverse bars and their pillars form a series of gantries staggered along the frame. We see that the first transverse bar (10a) is provided on its rear face with two single hooks (20), while under the second, third and fourth transverse bars (respectively 10b, 10c, and 10d) are mounted oscillating rods ( 21) carrying two vertical pegs (22).

Figure 4c shows the interlocking of two carriages of Figure 4a. We see that because of their ability to swing the rods (21) can fade forwards or backwards so as not to impede the interlocking.

Figure 5 shows the interlocking of two carriages of Figure lf. It can be seen that the platform (17) made in the form of a grid is connected to the longitudinal members by means of the auxiliary cross member (9) which serves as a nesting abutment.

A preferred embodiment of a shopping trolley according to the invention will now be described with reference to FIGS. 6 to 11b. This carriage is of the same type as that of Figure 3b.

Identical parts and / or performing the same functions have the same references. It can be seen in FIG. 6 that the shopping trolley according to this second embodiment has the following differences with that of the embodiment of FIG. 3b:

the rear uprights (3) of the chassis are not rectilinear but have a large offset towards the rear of their lower ends and a rearward extension of their upper ends in order to create a larger space under the stretcher formed by the rear ends of the uprights (3) and the maneuvering bar (4). This makes it possible to shift forward the rear wheels (8) the forces exerted by loads disposed in the rear part of the carriage and, consequently, to reduce the risk of tilting towards the rear of the truck if these loads are excessive;

- the spacer (16) connecting the ends of the transverse bars (10b, 10c) opposite the pillars (14b, 14c) which support them, and the first transverse bar (10a) are formed as a whole in a single section, realizing a continuous belt extending from one of the rear legs (3) of the frame to the pillar (14a) of the first transverse bar (10a);

an auxiliary pillar (23) is disposed between the spacer (16) and the underlying beam (1) substantially in the same vertical plane as that in which the point of attachment of the pillar (14b) of the second bar is located transverse section (10b) and auxiliary cross member (9);

the last transverse bar (10d) is not fixed between the two rear uprights (3) of the chassis, but is held on one side by the spacer (16) and on the other by an elbow fixed on the front of the upright (3) of the frame opposite that which carries the spacer (16).

As in the embodiment of Figure 3b, the point of attachment of the pillar (14a) of the first transverse bar (10a) is offset at the bottom of the pillar (14b) of the second cross bar (10b).

The auxiliary pillar (23), in addition to relieving the constraints of the cantilever supported by the opposite pillars (14a, 14b, 14c), protects the contents of the carriage during shocks on the side and on the front. This set of arrangements allows to widen and connect the platform (17) on the front part of the longitudinal members (1) between the front cross member (2) and the lower part of the pillars (14b) and (23). It also provides a more large initial insertion width when nesting two carriages together, which facilitates the nesting operation requiring less attention and precision on the part of the user in driving the carriage.

Also shown in Figure 6, three removable bags (S) disposed in the cells defined by the transverse bars (10a, 10b, 10c, 10d) by engagement with the hooks (12).

In Figure 7, it can be seen that the carriage is provided with a platform (17) extending rearwardly and upwardly for loading heavy or bulky objects that can not be accommodated in the bags (S ) hanging from the sleepers.

Compared to the previous embodiment, the asymmetric structure of this preferred embodiment of the invention provides the advantage of differentiating for the user an opening dedicated to the loading of the bags (S) over the belt (16). ), an opening without any obstacle located on the opposite side and dedicated to the passage of bulky loads. This arrangement is particularly useful when the user wants to use one or more of the cells defined by the transverse bars (10a, 10b, 10c, 10d) to place large volume products as shown in Figure 8.

In this embodiment, the platform (17), as best seen in Figures 9a and 9b, is fixed to the front of the frame by a portion inclined backwards and downwards that occupies the entire area defined by the front cross member (2), the front part of the longitudinal members (1) and the auxiliary cross member (9). This front portion of the platform (17) is connected by a step to a portion which extends rearwardly and upwardly to the level of the uprights (3). The side edges of this rear portion converge so as to define a trapezoid inverted relative to that defined by the frame members, the short side being at the rear and the long side being at the front. This arrangement ensures that the interlocking of two carriages is not prevented by the contact between the platform and one or other of the pillars supporting the transverse bars. The platform 17, as in the embodiment of Figure 3b is provided on one of its longitudinal sides of a vertical wall (18). A tie rod (19) connects the rear edge from the platform to the pillar (14b) which connects the second transverse bar (10b) to the frame spar (1).

The vertical wall (18) of the platform (17) advantageously combines with the belt (16) of the struts connecting the transverse bars (10a, 10b, 10c, 10d) to ensure the retention of the loads placed in height (Figure 8).

By its trapezoidal shape inclined backwards and upwards in the interlocking zone, the platform (17) is nestable without requiring movement or moving parts which is a guarantee of resistance and limits the risk of jamming moving parts together during the movements generated by the nesting.

To maintain the loads deposited on the platform (17) despite the inclination of the latter, a retaining clip (24) is pivotally mounted near the rear end of the platform. The stirrup (24) is made of a steel wire bent so as to take alternately two positions: one in which it is raised substantially in the plane of the rear edge of the platform to act as a restraint intended to avoid the falling loads back on the feet of the person driving the cart (Figure 9a), the other in which it is folded forward to form a restraint for a heavy load, for example a pack of bottles or a crate resting on the rear end of the platform (Figure 9b). The particular shape of the stirrup (24) shown in FIGS. 8 to 11b enables it to occupy alternately two stable positions which are not troublesome for the interlocking of the empty carriages, as can be seen more particularly in FIG. 10.

These figures also show that the trolley can be equipped with a child seat (25) which, advantageously, is designed so that it can easily be converted into a basket for receiving small items when it is not used for a child. child through a seat flap (26) which can rise to close the openings (27) passage of the legs of a child.
