Description

The invention relates to bins for collecting refuse of the type comprising a trough and a hinged lid.

From the prior art, in particular from the publication FR2900912 , a container for collecting rubbish is known, comprising a trough provided with two handles and a lid attached to the trough. The lid is connected to the trough by pivoting hinges adapted to allow the lid to pivot about the trough. These hinges are formed by a pin that is attached and intended to engage firstly in a hole made in an eyelet of the lid and secondly in a hole made in the handle. Such an axle is generally made of metallic material.

This hinge system has several disadvantages. Firstly, it means that in addition to the trough and the lid, a part has to be attached, which causes logistical effort. Furthermore, it is necessary that the handle of the container is hollow in order to accommodate the axle. However, when this is made by injection molding of plastic, the need for it to be hollow requires insertion of pins into the mold, which increases manufacturing cycle time and requires maintenance of the pins.

The object of the invention is to avoid these disadvantages by providing a container for collecting waste in which the application of the lid to the trough allows for shorter manufacturing cycles of the container and simpler and more generally cheaper logistical management.

To this end, the invention relates to a container for collecting waste, comprising a trough provided with at least one handle extending along a geometric axis and a lid attached to the trough,
characterized in that it comprises fastening means for fastening the lid to the trough, located at each free end of the handle, the fastening means comprising a connecting projection carried by the handle and a connecting recess formed in the lid, wherein the connection projection is designed to engage in the connection recess in such a way
that the lid is allowed to pivot with respect to the trough about the geometric axis.

Thanks to the fact that the fixing means for fixing the lid to the trough comprise a connecting projection carried by the handle and engaging in a connecting notch formed in the lid so as to allow the lid to pivot with respect to the trough about the geometric axis, it is no longer necessary to provide for the attachment of an axle inserted in a hollow handle.

This avoids having to manage an additional part, such as the axle, when manufacturing the container, which simplifies logistics. Also, a pin no longer has to be inserted into the mold of the handle when it is made by plastic injection molding, which limits the manufacturing time and avoids having to carry out maintenance on the pin. Finally, it is possible to make a tank entirely out of plastic since there is no longer a metal shaft.

According to a preferred embodiment of the invention, the connecting projection forms an extension which is integral with the free end of the handle and preferably extends along the geometric axis. This makes it possible to simplify the construction of the container and to allow easy pivoting of the lid around the geometric axis.

According to a preferred embodiment of the invention, which makes it particularly easy to attach the cover to the handle, the connection recess is formed in a tab of the cover, the connection recess being delimited by two legs which enclose the connection projection.

In order to further simplify the assembly of the cover on the handle, the connecting projection engages in the connecting recess in a snap-fit manner.

In order to further simplify the assembly of the lid on the handle, the locking engagement of the connecting projection in the connecting recess takes place through preferably elastic deformation of the legs when the lid is assembled on the trough.

According to a particular embodiment of the invention, the connecting projection is essentially rotationally cylindrical.

In order to ensure the easy snapping, the connection recess includes a receiving recess for receiving the connection projection, which forms a stopper for the connection projection when inserting the connection projection into the connection recess.

In order to ensure that the connection boss is properly locked in the receiving recess, the receiving recess is shaped complementarily to the shape of the connection boss.

In order to ensure that the lid stays properly in place on the trough, the connecting projection comprises an axial stop designed to prevent movement of the lid in a direction parallel to the geometric axis towards the free end of the handle.

In order to simplify its construction, the stop is advantageously constituted by a lug made on a free end of the connecting boss.

According to a particular embodiment of the invention, the handle is made of one material with the trough.

According to a particular embodiment of the invention, the container has two handles.

When the container comprises two handles, the container preferably comprises a central tab located between the two handles and provided with two connecting recesses cooperating with the connecting projections of the handles.

Detailed character description

In 1 an upper part, according to a vertical direction, of a container 10 for collecting waste is shown. The container 10 includes a trough 12 and a lid 14 attached to the trough 12 .

The container 10 can be a mobile container, for example with a capacity between 60 liters and 360 liters, for example about 120 liters or 240 liters.

The trough 12 is here essentially made of plastic, namely polyethylene, which is preferably partially or totally recycled, but according to a variant of this embodiment it may comprise another plastic or metal. The trough 12 has been manufactured using an injection molding process and is preferably in one piece. In the embodiment shown in the figures, the trough 12 here has a substantially rectangular cross-section. Of course, any other shape of the trough 12 is conceivable, for example an essentially cylindrical shape, in which case the cross section can be essentially round.

The cover 14 was also made using an injection molding process and is preferably in one piece. It comprises, for example, a base 14F, which is substantially rectangular here because of the substantially rectangular cross-section of the trough 12 and is delimited by a stiffening border 14B. Of course, any shape of lid may be suitable, as long as it allows the trough 12 to be covered.

The trough 12 has a substantially square opening at its upper end along the vertical direction. The trough 12 also includes, via a contour delimiting the opening, a stiffening collar 16 which makes it possible to mechanically stiffen the trough 12, in particular for lifting it when the container is emptied.

At least one, in this case two, handles 18 are attached over a section of this stiffening collar 16, so that the container 10 can be gripped by a person without any problems. In the present case, the handles 18 are of the same material, for example cast with the trough 12 .

The handles 18 extend along a geometric axis X-X, which is the same here and is substantially parallel to an edge of the trough 12. In the embodiment shown in the figures, the handles 18 are integral with the trough 12. In the embodiment shown in the figures, for example, the handles 18 are of substantially cylindrical shape.

The container 10 further includes attachment means 20 for attaching the lid 14 to the trough 12, located at the free ends 18L of the handles 18, i. H. At the ends opposite the center of the trough 12. In particular, since the container 10 comprises two handles 1, the container 10 comprises four fastening means 20 in all the embodiments shown in the figures.

The fastening means 20 each comprise an in 5 and 6 visible connecting projection 22, carried by the corresponding handle 18, and a connecting recess 24 formed in the lid 14.

Each connection notch 24 is formed in a tab 28 of the cover projecting from the latter substantially perpendicularly to the X-X axis.

In the embodiment shown in the figures, the lid 14 comprises two lateral tabs 28 arranged at each free end of the edge of the lid 14, from which the handles 18 are arranged. In the present case, the lateral tabs 28 form an extension of the stiffening border 14B.

in the in 1 and 2 In the embodiment illustrated, the cover 14 comprises two connection notches 24 for each fastening means 20. These two connection notches 24 are respectively in the external lateral surface 28E of the lateral tab which extends the lateral edge of the cover 14 (it is of the same material as this lateral edge, for example). inner side surface 281 of the tab is formed. The terms "outer" and "inner" are to be understood here in relation to the interior of the trough 12 .

in the in 3 until 6 In the embodiment illustrated, the cover 14 comprises only one connection notch 24 for each fastening means 20. This connection notch 24 is formed in the internal lateral surface 28I of the tab 28 which extends the lateral edge of the cover 14. The opposite outer side surface 28E of the tab 28 is here solid, as in particular in FIG 3 can be seen.

The interaction between the connecting projection 22 and a connecting recess 24 is described below, which applies in the same way to the first and the second embodiment.

As in 5 and 6 As can be seen, a connecting projection 22 forms an extension which is integral with the free end 18L of the corresponding handle 18 and here extends along the geometric axis XX. In particular, a connecting boss 22 comprises a body 23, which here is substantially cylindrical in revolution and extends along the geometric axis XX. Its cross section preferably has a diameter smaller than that of the handle 18 .

For a reason explained below, the connecting projection 22 has an axial stop 25 which is 6 can be seen.

The axial stop 25 is formed in particular by a lug formed on a free end 22L of the connecting projection 22. The approach is formed here by widening the cross section of the connecting projection 22 at its free end 22L.

in the in 1 and 2 The first embodiment shown, the connecting recesses 24 and the tab 28 define a channel in the tab 28, in which the connecting projection 22 is inserted. In other words, the connecting projection 22 completely traverses the lateral tab 28 in the direction of the axis XX. In 1 and 2 it can thus be seen that the axial stop 25 emerges from the connection notch 24 formed in the external lateral surface 28E of the lateral lugs 28.

In this particular embodiment, the lid 14 further includes a central tab 30 positioned between the two handles 18. As shown in FIG. The central tab 30 is provided with two connecting recesses 24 which cooperate with connecting projections 22 of the handles 18. In an alternative embodiment, not shown, the lid 14 could include two separate tabs 28 instead of the central tab 30 . The central flap 30 makes it possible to combine two flaps 28 into one.

As in particular in 4 and 5 can be seen, a connection recess 24 is delimited by two legs 32 which enclose the connection projection 22 . The two legs 32 are connected by a bulge 34 . Since the connecting projection 22 has an essentially round cross-section, the bulge 34 is essentially arc-shaped here.

The connection recess 24 is delimited by an interaction contour 36 defined by the two legs 32 and the bulge 34 and in particular in 4 and 5 can be seen. The interaction contour 36 thus comprises two substantially rectilinear edges which are not perfectly parallel in the embodiment shown in the figures and which connected at their ends by a bend forming a section of a circle through about 200°. It should be noted that the shape of the interaction contour 36 can vary. The rectilinear edges can thus be partially curved or rectilinear and parallel, and their spacing can vary. Likewise, the curve connecting the two rectilinear edges can form a more constrained portion of a circle or even be any curve depending on the shape of the connecting projection 22 .

In fact, the connecting projection 22 is designed to engage in the connecting recess 24 in such a way as to allow the lid 14 to pivot with respect to the trough 12 about the geometric axis X-X.

The connection projection 22 engages in the connection recess 24 in a snap-fit manner.

More precisely, the snap-in engagement of the connecting projection 22 in the connecting recess 24 takes place here through, preferably elastic, deformation of the legs 32 during the assembly of the lid on the trough.

In the embodiment shown in the figures, it is therefore provided that the minimum distance between the branches 32, and therefore here the minimum distance between the straight edges of the interaction contour 36, is less than the diameter of the body 23 of the connecting projection 22, i.e. H. in its cross-section before the widening formed by the axial stop 2825.

A force must therefore be exerted on the connecting projection 22 to allow the blocking point formed by the cross-section of the interaction contour 36 to be passed, in which the local spacing of the branches 32 is less than the diameter of the connecting projection 22 . This force can be obtained by pressing the wall of the lid 14 by a person when assembling the lid 14.

Deformation of the legs 32 then space them apart and allow the connecting projection 22 to pass through. After the connecting projection 22 has passed the blocking point, the legs 32 partially close again around the connecting projection 22 due to their elasticity in such a way that they span it, as in 4 until 6 can be seen.

In order to ensure that the connection protrusion 22 remains locked in the connection recess 24 after it has been inserted therein, the connection recess 24 is provided with a receiving recess 38 which forms a stop for the connection protrusion 22 when the connection protrusion 22 is inserted into the connection recess 24.

The receiving recess 38 is shaped to complement the shape of the connecting projection. In the embodiment shown in the figures, this receiving niche is delimited by the bulge 34 and is thus defined by the arc of the interaction contour 36 . Since the connecting projection 22 has a round cross-section, the receiving niche 38 delimited by the bulge 34 is in the form of a circular arc.

After the connecting projection 22 has passed the blocking point formed by the cross-section of the interaction contour 36, in which the local spacing of the legs 32 is less than the diameter of the connecting projection 22, it penetrates into the receiving recess 38 from which they no longer exit unless a pulling force is applied that allows the blockage to be re-entered.

The invention is not limited to the embodiments shown, and other embodiments and variants will be apparent to those skilled in the art.

It can also be envisaged that the container comprises only a single handle, for example extending over the entire width of the trough. In this variant, the cover would not have four, but two fastening means according to the invention. Furthermore, the lid would not include a central tab, but only two lateral tabs located near each free end of the handle.
