OPENING / CLOSING DEVICE WITH DOUBLE HINGE. The present invention relates to the field of waste storage management. More specifically, the invention relates to a device for opening / closing the closure of a storage area frame comprising an opening plane, the closure being movable about a first axis of rotation between a working position in one rest position in which it covers (at least partially) the opening plane, the device comprising: a storage area frame, a closure, and a first hinge, comprising a first primary element secured to the frame of the storage area and a second primary element integral with the closure, said first primary element and second primary element having a profile (a cross section) locally concentric with said first axis of rotation. Such a device is known to those skilled in the art, especially in the field of containers (or dumpsters), docked or not, of waste. In general the closure can be manipulated so as to take at least one rest position and an active position. The closure is generally closed in the rest position (for example for storage or transport) and open in the active position (for example for loading the bucket, or tamping the contents of the bucket). In these devices, the storage area is the interior of the container, the frame comprises the lateral uprights of the container, and the opening plane is generally a horizontal plane located above the container. The closure may be unsealed, partially or completely sealed, for example a rigid cover, a tarpaulin, generally flexible (non-rigid) and guided by a system of double rails fixed on the frame or on the container, a grid, etc. However, in the context of the opening / closing of a tarpaulin, this poses problems of handling and safety because the operators must climb at the top of the containers to manipulate the tarpaulins, problems of deformation of the structures by force of openings / successive closures, and therefore sealing problems. As a result, the buckets are impractical to use and their use implies a high maintenance cost. The rigid closures, for example in the form of covers, are generally fixed to the frame by a hinge arranged on one side of the container, to open the lid on the other side, which involves positioning the container on one side or the other, so that the opening of the lid can allow the loading of the container, and the passage of tamping means for example. The present invention aims to overcome these disadvantages by providing a simple solution to implement and can be adapted to any container position.
With this objective in view, the device according to the invention, also in accordance with the preamble cited above, is essentially characterized in that: the closure is movable about a second axis of rotation different from said first axis of rotation between said rest position and a second working position in which it discovers at least another part of the opening plane, the device further comprising a second hinge comprising a first secondary element secured to the frame of the storage area and a second secondary element integral with the closure, said first secondary element and second secondary element having, in the rest position, a profile (a cross section) locally concentric with said second axis of rotation. With this configuration: in the rest position, the first primary element and the second primary element are rotatable according to a second axis of rotation different from said first axis of rotation, and in the working position, the first primary element and the second element primary are not rotatable along said second axis of rotation. Preferably, one of said first primary element or second primary element has an elongated profile comprising a first primary width and a first primary maximum diagonal such that the first primary maximum diagonal is greater than the first primary width, and the other of said first primary diagonal primary element or second primary element has an at least partially rounded profile comprising a substantially circular portion of primary diameter greater than the first primary maximum diagonal, and an opening of primary width greater than the first primary width.
In one embodiment, the device further comprises means for thrusting the closure, configured to rotate the closure around said first axis of rotation, so as to position the closure in the first working position and / or in the rest position; and / or around said second axis of rotation, so as to position the closure in the second working position and / or in the rest position. In one embodiment, the thrust means are removable relative to the frame and / or the closure. Advantageously, the first and second hinges are symmetrical with respect to a plane of symmetry, in this case parallel to the first axis of rotation. That is to say that the first primary element and the first secondary element, as well as the second primary element and the second secondary element have at least locally symmetrical profiles relative to said plane of symmetry. In one embodiment, one of said first secondary element or second secondary element has an elongated profile including a first secondary width and a first secondary maximum diagonal such that the first secondary maximum diagonal is greater than the first secondary width, and the another of said first secondary element or second secondary element has an at least partially rounded profile, comprising a substantially circular portion of secondary diameter greater than the first secondary maximum diagonal, and an opening of secondary width greater than the first secondary width.
In one embodiment, in the working position, the opening angle between the opening plane and the closure is included in the set] A; B] with A = 0 °; and B> 90 °.
In one embodiment, the device further comprises means for limiting the rotation of the first and / or second hinge. In one embodiment, said closure pushing means are also configured to rotate the closure around said second axis of rotation, so as to position the closure in the second working position and / or in the rest position. Thanks to the invention, - from the exit of the rest position to the first working position, and vice versa, the first primary element and the second primary element, as well as the first secondary element and the second secondary element, are not more mobile in rotation about the second axis of rotation; and - as soon as it leaves the rest position to the second working position, and vice versa, the first secondary element and the second secondary element, as well as the first primary element and the second primary element, are no longer rotatable around it of the first axis of rotation. Other characteristics and advantages of the present invention will emerge more clearly on reading the following description given by way of illustrative and nonlimiting example and with reference to the appended figures in which: FIG. 1 illustrates a front view of an embodiment of the device according to the invention in a first working position with opening of the right-hand closure, FIG. 2 illustrates the device of FIG. 1 in a second working position with opening of the left-hand closure, FIG. a cross section of a first primary element and a second primary element, during a relative movement assimilated to a translation, FIG. 4 illustrates a cross section of a first hinge, in the rest position, FIG. a cross section of the first hinge of FIG. 4, in the working position, FIG. 5A illustrates a three-quarter view of FIG. 5, FIG. 6 illustrates a partial view of an embodiment of thrust means cooperating with a closure, Figure 7 illustrates a partial cross section of an embodiment of a first primary element and a second primary element, the FIG. 8 is a partial cross-section of another embodiment of a first primary element and a second primary element; FIG. 9 is a partial cross-section of another embodiment of a first primary element; and a second primary element equipped with stops, FIG. 10 illustrates a front view of an embodiment of the device according to the invention comprising two pushing means and a common selective actuating means, FIG. 10A is an enlargement of the zone A of FIG. 10, and FIG. 11 illustrates a three-quarter view of rotating drive means cooperating with a primary element. The invention is advantageously implemented in the field of containers (or skips), docked or not, of waste. Figures 1 and 2 illustrate an embodiment of the invention implemented for such containers. For simplicity of the present description, only such containers are described. Thus, the device according to the invention comprises a closure 10, in this case a cover. The closure 10 is movable as described below. The walls of the container define in themselves the frame 11 of a storage area Z, the container comprising an opening plane P, in this case a horizontal plane disposed on the top of said container. The closure 10 is movable about a first axis of rotation X between a rest position in which it covers the opening plane P and a first working position in which it discovers at least part of the opening plane (FIG. 1). The mobility of the closure 10 with respect to the container 11 is ensured in particular by virtue of a first hinge 12, comprising a first primary element 14 integral with the frame 11 of the storage area and a second primary element 16 integral with the closure 10, and configured to cooperate with said first primary element 14.
According to the invention, the closure 10 is also movable about a second axis X 'of rotation, different from said first axis X of rotation, between said rest position and a second working position in which it discovers another part at least of the opening plan (Figure 2). To this end, the device further comprises a second hinge 12 'comprising a first secondary element 14' integral with the frame 11 of the storage area and a second secondary element 16 'integral with the closure 10, and configured to cooperate with said first element secondary 14 '. With this configuration, the closure 10 is completely removable, that is to say it can be very easily detached and removed from the container 11. Preferably, the first axis X and the second axis X 'are parallel. Thus, if FIG. 1 represents a first opening in rotation about the X axis, in the right case, one can, thanks to the invention, realize an opening in rotation about the second axis X ', in the left case ( Figure 2), said container 11, without moving (return) it. Thanks to this feature, for the same position of the container 11, the closure 10 can be open on one side (Figure 1) or on the other (Figure 2). Thus, a container no longer has to be arranged in a particular sense of the opening sense of its closing, which saves time when placing it on the ground. The same container has, thanks to the invention, a sense of opening of its reversible closure. In the first and / or second working position, the opening angle α between the opening plane P and the closure 10 is included in the set] A; B] with A = 0 °; and B> 90 °. In one embodiment, the aperture angle a maximum is equal to 94 °. An opening angle slightly greater than 90 ° allows for example to implement means for tamping the contents of the storage area, known to those skilled in the art. According to the invention, the rotation around the X and X 'axes is implemented thanks to a particular profile of the hinge elements.
In particular, at least one of said first primary element 14 and second primary element 16 has, in the rest position, a profile that is at least partially concentric with said first axis of rotation X, and at least one of said first secondary element. 14 'and second secondary element 16' has, in the rest position, a profile locally at least partially concentric with said second axis of rotation X '. Advantageously, one of said first primary element 14 or second primary element 16 has an at least partially rounded profile, comprising a substantially circular portion of primary diameter D1 and an opening of primary width L1. In one embodiment, FIGS. 3 to 6, one of said first primary element 14 or second primary element 16, in this case said second primary element 16 has an elongated profile comprising a first primary width 11, a first primary maximum diagonal d1, and a first length lg1, such that the first primary maximum diagonal d1 is greater than the first primary width 11. The other of said first primary element 14 or second primary element 16, in this case the first primary element 14, presents an at least partially rounded profile, comprising a substantially circular portion of primary inner diameter D1 greater than the first primary maximum diagonal d1, and an opening of primary width L1 greater than the first primary width 11 and less than the first length lgl or at least first maximum diagonal primary d1. In the same way, one of said first secondary element 14 'or second secondary element 16', in this case said second secondary element 16 ', also has an elongate profile comprising a first secondary width 11', a first secondary maximum diagonal dl 'and a first secondary length lgl' such that the first secondary maximum diagonal dl 'is greater than the first secondary width 11'. And the other of said first secondary element 14 'or second secondary element 16', in this case the first secondary element 14 ', has an at least partially rounded profile comprising a substantially circular portion of secondary diameter Dl' greater than the first diagonal secondary maximum dl ', and an opening of secondary width Li' greater than the first secondary width 11 '. Preferably, the first primary element 14 and the first secondary element 14 ', as well as the second primary element 16 and the second secondary element 16' have a respective cross-section mirror one of the other, in this case symmetrical by relative to a plane of symmetry S perpendicular to the plane of opening P, in this case vertical. As illustrated in FIGS. 1 and 2, the frame 11 of the storage area comprises a longitudinal plane of symmetry, and the first 12 and the second 12 'hinge are symmetrical with respect to said vertical plane of symmetry S. To block the rotation and to limit the opening angle a, the device further comprises means for limiting the rotation of the first and / or second hinge, in this case a stop 17 (respectively 17 '). Advantageously the stop is integrated with at least one of said first primary element 14, first secondary element 14 ', second primary element 16, and second secondary element 16', in this case the stop 17 is integrated with the first primary element 14 ( Figures 3 to 5), or the second primary element 16 (Figure 9) by the profile thereof. In another embodiment, FIGS. 7 to 9, the other of said first primary element 14 or second primary element 16 has an at least partially rounded profile, comprising a substantially circular portion cooperating with said substantially circular portion of inner primary diameter D1 and of outside primary diameter R1 less than the first primary width L1 of said opening. The opening angle (3 (FIG. 7) between the axis of rotation X, X 'and the ends of the substantially circular portion in this case of the first primary element 14 is less than 180 ° if the outside primary diameter R1 is substantially equal to the inner primary diameter D1 (FIGS. 7 and 9) and possibly greater than the first primary width L1 of said opening, or greater than 180 ° if the outer primary diameter R1 is smaller than the first primary width L1 of said opening ( 8), as illustrated in particular in FIG. 6, the device according to the invention may further comprise thrust means 13 of the closure 10, configured to pivot the closure 10 around said first axis of rotation X, and / or around said second axis of rotation X ', so as to position the closure 10 in the working position and / or in the rest position, in this case the thrust means 13 comprise an actuator or jack (hydraulic / pneumatic) 1 31, an arm 132, and actuating means 133 for actuating said jack, for example a lever for manual actuating means (Figure 6). The actuating means can also be electric. In one embodiment, Figures 1, 2 and 6, the hydraulic cylinder 131 is configured to be connected to a portion of the closure 10 preferably removably.
In this case the cylinder 131 is connected to the closure 10 by a part 101 equipped for example with a pin, the piece 101 protruding cylindrical, which allows the rotation of said part 101 (thus the closure) relative to a circular recess one end of the cylinder 131 (Figure 6) with which it cooperates. The arm 132 is non-expandable when the actuator 131 is in action. It is possibly rotatable relative to the hydraulic cylinder 131, so that the angle between the arm 132 and the cylinder 131 is variable and adjustable. The arm 132 is configured to be connected to another part of the closure 10, preferably removably. In this case, the arm 132 is connected to the closure 10 by a part 102 equipped for example with another pin. The piece 102 projects cylindrical, which allows the rotation of said piece 102 (thus the closure) relative to a circular recess of one end of the arm 132. The part 102 is advantageously concentric with the axis of rotation X. Thanks to this configuration, the thrust means 13 are removable relative to the frame 11 and / or the closure 10. The storage area frame 11 may further comprise retaining means 19, 19 '(Figures 1 and 2), to make said thrust means 13 integral with the frame 11 at least during the opening / closing of the closure 10. Advantageously, the closure also comprises parts 101 'and 102' projecting cylindrical, respectively symmetrical parts 101 and 102 relative to the plane of symmetry S (in the rest position).
Thus, advantageously, the same thrust means 13 of the fastener 10 can be used to rotate the fastener 10 around said second axis of rotation X ', so as to position the fastener 10 in the second working position and / or in position rest.
In another embodiment, the thrust means 13 are permanently secured to the frame 11 and / or to the closure 10 (FIG. 10) and comprise: a first jack 131 1, actuable by a first actuating means, and configured to make pivoting the closure 10 about said first axis of rotation X, for example similar to that illustrated in FIG. 1, and a second actuator 131 2, actuable by a second actuation means, and configured to rotate the closure 10 around said second axis of rotation. rotation X ', for example similar to that illustrated in FIG.
Thus each cylinder can be activated by means of actuation which are specific to it. However, advantageously, the first actuating means and the second actuating means are the same 133, which allows cost savings. In this case, the thrust means 13 further comprise selective distribution means 134 (FIG. 10) configured to selectively actuate the first cylinder 131 1 or the second cylinder 131 2.
In the particular case where the thrust means 13 are permanently integral with the frame 11 and / or the closure 10, the thrust means 13 can be completed by means of rotational drive 20 (FIG. 11), concentric at least locally with the first axis of rotation X and / or the second axis of rotation X ', and whose profile cooperates with the closure 10, that is to say that it has at least locally a profile adapted to that of the closure 10, in this case by the first primary element 14. These rotational drive means 20 comprise for example, by axis of rotation, a rod 21 actuated by the cylinder 131 1, 131 2 corresponding, secured to the first primary element 14 by the intermediate of a tubular piece 22, which allows the rotation of the closure 10. The rotating drive means 20 cooperate with a part (not shown) integral with the frame 11 and comprising a tubular recess in which said tubular piece 22 is movable e in rotation (Figure 10A). During a rotation about the first axis of rotation X, for example when leaving the rest position (opening) and vice versa when returning to the rest position (closing), the first primary element 14 and the second element primary 16 perform a relative rotational movement about the first axis of rotation X (represented by an arrow Figure 4), while the first secondary element 14 'and the second secondary element 16' perform a relative movement assimilated to a translation, c ' that is to say in this case a rotation along a plane tangent to the circular path of said second secondary element 16 'around said first axis of rotation X. Hence the advantageous shape of the respective profiles of said elements.
Upon leaving the rest position, to the first working position, the first primary element 14 and the second primary element 16 are no longer mobile in translation (that is to say along a tangent to a rotation of the second primary element 16 around the second axis of rotation X '); and the first secondary element 14 'and the second secondary element 16' are no longer rotatable along the second axis of rotation X '. Similarly, during a rotation about the second axis of rotation X ', for example when leaving the rest position (opening) and vice versa when returning to the rest position (closing) from a second position of the first secondary element 14 'and the second secondary element 16' effect a relative rotational movement about the second axis of rotation X ', while the first primary element 14 and the second primary element 16 perform a relative movement similar to a translation (represented by an arrow Figure 3), that is to say in this case a rotation along a plane tangent to the circular path of said second primary element 16 about said second axis of rotation X '. Hence the advantageous shape of the respective profiles of said elements. From the exit position to the second working position, the first secondary element 14 'and the second secondary element 16' are no longer mobile in translation (that is to say along a tangent to a rotation second secondary member 16 'about the first axis of rotation X); and the first primary element 14 and the second primary element 16 are no longer rotatable along the first axis of rotation X. The present invention is not limited to the previously described embodiments. For example, the shape of the container 11 may be other than that of a parallelogram. The hinges 12 and 12 'symmetrical, that is to say reflections from one another, have been shown on two sides facing each other, but can also be mounted on two adjacent sides of a frame 11.
Each hinge 12, 12 'may respectively comprise a plurality of first primary elements 14, a plurality of first secondary elements 14', a plurality of second primary elements 16, and a plurality of second secondary elements 16 '. Finally, other storage area racks 11 than a container can be implemented.
