    [0004] Object of the invention
    [0005] The present invention relates to a container with a lid opening device; where the opening device is applicable primarily to a garbage container. It is an opening device that simplifies the opening of the lid and provides a smooth and practical operation during the opening and closing of the lid, which is attached to the container by means of a hinge. It is essentially emphasized that when the opening device is actuated, the stability of the entire container is maintained by avoiding unwanted movements in the entire container.
    [0007] Technical problem to solve and background of the invention
    [0008] At present, containers with a lid are known; where said lid is coupled in correspondence with a mouth of the respective container through an upper articulated connection, so that the cover can be folded around said articulated connection to access an interior space of the container, so that in a position of rest the lid closes the mouth of the container.
    [0010] In some cases, the containers include lid opening devices to be able to open the respective container by manipulating a first articulated piece like a pedal that is coupled to the container by means of a lower articulated connection arranged in correspondence with the bottom of the container; where each one of said opening devices comprises several articulated parts and other elements associated with said articulated parts.
    [0012] In line with what was said in the previous paragraph, patents with publication number WO 2016110858, DE 19809331 C1 and GB 353330, describe some devices for opening the lids of the containers, so that in each case, the The opening device comprises the first articulated piece, a second articulated piece, an intermediate element that connects the two articulated pieces, and a rear element that connects the cover and the second articulated piece.
    [0013] With this arrangement described, when the first articulated part is acted upon by making it rotate in a first direction of rotation, its articulated movement causes the second articulated part to rotate and this moves the rear element downwards, folding down the cover until it is placed in a position of opening in which the mouth of the container is released; where in this opening operation the rear element is subjected to a tensile stress.
    [0015] On the other hand, when it stops acting on the first articulated piece, the cover recovers its rest position, as occurs with the rest of the elements of the opening device; all this due to the weight of the lid itself, which closes the mouth of the container.
    [0017] In all cases, both the first articulated piece and the second articulated piece, as well as the intermediate element, these three elements are located below the bottom of the container.
    [0019] These described opening devices present a certain complexity due to the need to incorporate two joint pieces and the intermediate element that associates both joint pieces. This complexity also increases the final cost of the product and hinders the proper functioning of the opening device.
    [0021] Also known is the utility model with publication number in Spain ES 1207689 referring to a container with a lid opening device that is owned by the same owner as the present invention. Said opening device comprises an articulated piece like a pedal and a tie that connects the lid of the container with the articulated piece that is located in a lower part of the container; where the lid is coupled to the container by means of a hinge. With this arrangement described, when a user steps on the articulated piece, the lid is folded down, releasing the mouth of the container, and when the user stops stepping on the articulated piece, the lid recovers its rest position, closing the mouth of the container. During these operations of opening and closing the lid, when stepping on the articulated part, a significant problem of instability is generated that causes undue displacement of the entire container and consequently its normal operation.
    [0022] Description of the invention
    [0023] In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a container with a device for opening a lid; where the lid is configured to engage in correspondence with a mouth of the container by means of a first articulated connection.
    [0025] The opening device comprises a crank, a pedal and a strap with a flexible structure that connects the crank with the cover.
    [0027] The pedal and the crank are coupled to a bottom of the container by a second articulated connection and by a third articulated connection, respectively; where the third articulated connection is located below the second articulated connection and below the pedal.
    [0029] A part of the crank is housed in a through hole in the pedal; where a first end section of the crank is coupled to the bottom of the container by means of the third articulated connection; and where the crank is in contact with a portion of a perimeter edge that delimits the through hole of said crank.
    [0031] One end of the tie rod connects with a second end section (opposite the first end) of the crank above the pedal and above the second articulated connection, while at least one other end of the tie connects with an end zone of an extension integral to the lid; where said end zone is remote from the first articulated connection a distance.
    [0033] The tie comprises an intermediate section that is in contact with a curved-convex surface of the container.
    [0035] The curved-convex surface of the container constitutes a sliding contact surface of the tie rod which is subjected to a tensile stress at least during the folding of the lid around the first articulated connection; where said curved-convex surface is located in a confluence zone of a side wall and the bottom of the container.
    [0036] The tie includes the intermediate section, a vertical section configured to join the lid, and an inclined section configured to join the crank.
    [0038] The inclined section of the tie-rod faces an inclined plane at the bottom of the container; where said inclined plane descends until it joins the curved-convex surface; and where said inclined plane ascends until it empties into a recess in the container in which the pedal is housed.
    [0040] In one embodiment of the invention, the entire extension of the vertical section of the tie comprises a single branch, while in another embodiment the vertical section of the tie comprises two divergent end branches that are joined at their two ends to two end zones of the integral extension to the lid.
    [0042] The crank includes a curved surface that is in contact with the portion of the perimeter edge that delimits the through hole of said crank; where during at least the mobility of the pedal pedal the strut remains in tension
    [0044] It should be noted that the lid opening device uses a simple mechanism formed by the pedal and the crank, and the flexible structure strap is also highlighted as an element that pulls the lid by rubbing on the curved-convex surface of the container itself; where said curved-convex surface is located in a confluence zone of a side wall and the bottom of the container.
    [0046] It is important to achieve a good sliding of the tie rod on the curved-convex surface of the container so that the pedal and crank mechanism operates smoothly while maintaining stability at all times in order to avoid displacement and unwanted movements of the container assembly, mainly when a user steps on and press with your foot on the pedal to carry out the opening of the lid. In this way, the necessary traction force is achieved to lift the lid and, in turn, the container does not experience the unwanted movements referred to by the action of the pressure on the pedal.
    [0048] For this, the inclined plane of the bottom of the container allows to have a lever arm sufficiently dimensioned to reduce the effort of the tread on the pedal, where said inclined plane is a continuation of the curved-convex surface that corresponds to the confluence zone of the side wall and the bottom of the container, as previously referred to.
    [0050] Said lever arm corresponds to a distance measured between the third articulated connection of the crank and the connection point of the tie rod to said crank.
    [0052] The embodiment of the invention where the tie comprises the two divergent branches connected to the cover improves stability and smoothness in the movement of raising and lowering the cover during its opening and closing.
    [0054] The strap can comprise a single piece over its entire length as referred to above, although in the preferred embodiment shown in the figures, the strap is made up of two parts connected to each other; where an upper part of the tie comprises the two divergent branches and a lower part of the tie is the one that slides supported on the curved-convex surface of the container.
    [0056] This allows us to use different materials, since it is preferable that the lower part that slides supported on the curved-convex surface is more flexible or malleable than the upper forked part formed by the two divergent branches.
    [0058] With this arrangement described, the manufacturer will even be able to mold the cap and the upper forked part of the tie rod in the same plastic material, reducing an assembly part with the consequent saving in manufacturing costs.
    [0060] The flexible lower part of the tie rod can be manufactured in any suitable material, and even replaced in case of breakage without affecting the rest of the elements of the container.
    [0062] Below, to facilitate a better understanding of this specification and forming an integral part thereof, a series of figures is attached in which the object of the invention has been represented by way of illustration and not limitation.
    [0064] Brief description of the figures
    [0065] Figure 1.- Shows a perspective view of the container with opening device of a lid, object of the invention. The container lid is in a closed position.
    [0066] Figure 2.- Shows a sectioned elevation view of the container of the invention, where its lid is located in the open position.
    [0067] Figure 3.- Shows a sectioned elevation view of the container of the invention, where its lid is located in the closed position.
    [0069] Description of an embodiment of the invention
    [0070] Considering the numbering adopted in the figures, the container 2 with an opening device 1 of a lid 14 includes a mouth, in correspondence with which said hinged lid 14 is engaged.
    [0072] On the container 2 a crank 15 and a pedal 3 that is located in correspondence with a bottom 4 of said container 2 are coupled, so that the container 2 includes the mouth that is closed by the lid 14 when it is located in a folded position , as shown in Figures 1 and 2, while when the lid 14 is located in an unfolded position, the mouth of the container 2 is released in order to access an interior space of said container 2, as shown in Figure 3.
    [0074] The lid 14 is coupled to the container 2 by means of a first articulated connection 5. Instead, the pedal 3 is coupled to the bottom 4 of the container 2 by means of a second articulated connection 6, and the crank 15 is coupled to the bottom of the container by a third connection hinge 16 which is located below the second hinge connection 6 and also underneath the pedal 3.
    [0076] The opening device 1 of the cover 14 comprises the pedal 3, the crank 15 and a strap 7 of flexible structure that connects the crank 15 with the cover 14.
    [0078] A part of the crank 15 is loosely housed inside a through hole 17 of the pedal 3, at the same time a first end section of the crank 15 is coupled to the bottom 4 of the container by means of the third articulated connection 16 that is located below the pedal 3 as referred to above.
    [0079] Instead, one end of the tie rod 7 connects with a second end section (opposite the first end section) of the crank 15 above the pedal 3 and above the second articulated connection 6, while at least one other end of the tie 7 connects with an end zone 8a of an extension 8 integral with the cover 14; where said end zone 8a is away from the first articulated connection 5 a distance "x".
    [0081] On the other hand, the tie 7 comprises an intermediate section 7a that is in contact with a curved-convex surface 11 of the container 2, so that said curved-convex surface 11 constitutes a sliding contact surface like a pulley that facilitates the displacement of the tie 7 subjected to a tensile stress during the folding of the lid 14 to place it in the folded or unfolded position.
    [0083] The tie 7 comprises the intermediate section 7a, a vertical section 7b that joins the cover 14, and an inclined section 7c that joins the crank 15; where said inclined section 7c faces an inclined plane 12 of the bottom 4 of the container 2; and where said inclined plane 12 descends until it joins the curved-convex surface 11, at the same time that said inclined plane 12 ascends until it empties into a recess 9 of the container 2 in which the pedal 3 is housed.
    [0085] The inclined plane 12 of the bottom 4 of the container 2 makes it possible to have a lever arm sufficiently dimensioned to reduce the effort of the foot on the pedal 3, where said inclined plane 12 is a continuation of the curved-convex surface 11 that corresponds to a zone of confluence of a side wall 13 and the bottom 4 of the container 2.
    [0087] Said lever arm corresponds to a distance "y" measured between the third articulated connection 16 of the crank 15 and the connection point of the tie rod 7 to said crank 3, as shown in figure 2.
    [0089] In one embodiment of the invention, the entire extension of the vertical section 7b of the tie 7 comprises a single branch, while in another embodiment said vertical section 7b of the tie 7 includes two divergent end branches 10 that are joined at their two ends to two zones ends 8a of two extensions 8 integral with the cover 14.
    [0090] With this arrangement described and the container 2 being closed with the lid 14 in the folded position, sealing the mouth of the container 2, a user proceeds to step on and press down with his foot on the pedal 3, whereby said pedal 3 rotates in a first direction of rotation around the second articulated connection 6 pulling the cover 14 by means of the crank 15 and the tie rod 7, where the crank 15 also rotates in the same direction of rotation as the pedal 3 pulling the tie 7, so that that during this operation, said lid 14 is placed in the deployed position in which the mouth of the container 2 is released.
    [0092] On the other hand, when the user stops pressing his foot on the pedal 3, the lid 14 recovers by gravity its folded position, sealing the mouth of the container 2.
    [0094] The crank 15 includes a curved cam-like surface 15a that is always in contact with a portion 18 of a perimeter edge that delimits the through hole 17 of said crank 15; where during the rotation of the pedal 3 in one direction or the other, the crank 15 adopts different angular positions around its third articulated connection 16; and where during the rotation of the pedal 3 to open the lid 14 of the container, said pedal 3 pushes the crank 15, urging its rotation against the resistance offered by the weight of the lid 14.
