Description

Retaining device with automatic coupling for containers.
Field of the invention
This invention pertains to a retaining device aimed at avoiding the unintentional movement with respect to the ground of a container for waste or other materials. Background of the Invention
There are several types of waste containers characterized by different opening systems for the introduction and removal of waste. A relevant problem for such containers is related to their unintentional movement. This can occur in strong wind areas, but it can also be caused by acts of vandalism or insane amusement.
The same problem is found in containers for collection, storage or transport of other materials.
The problem has been examined in a high number of patents, most of which discussing how to block the wheels of containers or how to fix a rotating part to a fixed part. Among these are mentioned WO-A-2004/050 512, DE 20 2009 016213 and US 2004/084393. In particular, WO-A-2004/050 512 describes a retaining device for containers having wheels, comprising a base, whereby the base includes a frame having a sliding support for rotating elements and a lower platform having, on the side facing the frame, a body with rotating means that slide on the rotary support for rotating elements of the frame, and a pin blocked by a catch passes through a hole of the support for rotating elements and a hole of the body with rotating means and allows the rotation of the lower platform on the frame but prevents its detachment. The present invention deals instead with a container without wheels lifted by mechanical means.
Summary of the invention
The aim of the present invention is to make available to users a retaining device with automatic coupling for containers.
This and further aims are accomplished by the above-mentioned device, which includes a base fixed to the ground and two hook-release mechanisms, each of which is fixed on a side of the container and on a higher platform.
The base includes a frame, a lower platform and a median platform. The frame is fixed to the ground and it consists of perimetral metal bars arranged to form a polygon or a circle. Further metal bars reinforce the frame and connect it to a sliding support for rotating elements. The frame can have perimetral walls along its long sides.
The lower platform consists of a metal plate. On the side facing the frame there is a body with rotating means that slide on the rotary support for rotating elements of the frame.
Elastic means join the lower platform to the frame.
The lower platform is preferably contained in the thickness of the frame. A pin blocked by a catch passes through a hole of the support for rotating elements and a hole of the body with rotating means and allows the rotation of the lower platform on the frame but prevents its detachment.
The median platform consists of a metal plate. At least two first cavities extend on its upper side, along its major central axis. These first cavities are placed near the minor sides of the medial platform. At least two second cavities extend on the upper surface, along the major central axis of the median platform. Each second cavity is in communication with a first cavity. Within each second cavity a cylindrical bar is housed, which spreads along the major central axis of the median platform. The ends of each cylindrical bar are blocked on the median platform. Each second cavity can be placed underneath a first cavity.
The median platform is provided, along its major sides, with perimetral walls.
Between the lower platform and the median platform at least two rails are positioned, which extend parallel to the minor axis of the two platforms. Each rail includes a metal supporting element welded to the lower platform and a metal plate welded to the median platform. The metal plate can move in both directions with respect to the supporting element sliding on rotating elements. An elastic element is fixed to each end of each metal plate of the rails and to the lower platform. These elastic elements prevent the translation of each metal plate beyond a certain limit, and restore the median platform to its central position with respect to the lower platform at the conclusion of any movement of the median platform. The upper platform consists of a metal plate. It has at least two reliefs that lie on its underside, centrally and along its major axis. The section of the reliefs of the upper platform is complementary to that of the first cavities of the median platform.
Near the edges of the major sides of the upper platform there are rollers or wheels. The container is fixed to the upper platform.
Each hook-release mechanism includes a part fixed to the upper platform, a part fixed to the container and an inextensible element such as a rope or a shaft.
The part fixed to the upper platform includes at least a hook rotating on a shaft. One end of each shaft is fixed to the wall of the container while the other end is fixed to a casing fastened to a wall of the container that preferably extends under its lower base.
Each hook is joined to an elastic element either fixed to the container or to the casing.
The part fixed to the container of the hook-release mechanism includes a pin fixed to a first plate and a second plate. The second plate is omega-shaped and two of its walls are welded to the container. The second plate has two rails on the inner walls and a vertical slit in the central wall. The first plate moves vertically in the rails of the second plate and the pin slides within the slit. On the central wall a hollow element which houses a pin is fixed from the outer side.
One end of each inextensible element is fastened to a hook of the part fixed to the upper platform of a hook-release mechanism, while the other end of the inextensible element is fastened to a pin of the part fixed to the container of the same hook- release mechanism.

Description of a preferred embodiment of the invention
The above-mentioned device includes a base 1 fixed to the ground and two hook- release mechanisms fixed to the container 2 for waste and to an upper platform 3. The base 1 includes a frame 11, a lower platform 12 and a median platform 13.
The frame 11 consists of four perimetral metal bars arranged to form a rectangle, and of four further metal bars securing a ring 111 to the perimetral bars. This ring 111 has an outer perimetral edge 112 and an inner perimetral edge 113 delimiting a flat rail. Arms 114 join the ring 111 to a central circular plate 115. The frame 11 has low perimetral walls 116 along its long axis. The frame 11 is fixed to the ground.
The lower platform 12 consists of a rectangular metal plate. On the same lower platform 12 is fixed a ring 121 with arms 122 linking it to a central round plate 123. On the ring 121 are fixed some houses 124, each of which houses a sphere 125.
Springs 126 link the lower platform 12 to the perimetral bars of the frame 11.
As illustrated in Fig. 8, when the base is assembled the ring 121 of the lower platform 12 overlaps the ring 111 of the frame 11. The spheres 125 of the ring 121 run on the flat rail of the ring 111 between its perimetral edges 112, 113.
The lower platform 12 is contained in the thickness of the frame 11. A pin 4, passing through a central hole 117 of the ring 111 and a central hole 121 of the ring 121 and blocked by a catch, allows the rotation of the lower platform 12 on the frame 11 but prevents its detachment. If the lower platform 12 is rotated, it restores the original position with respect to the frame 11 by means of the springs 126.
The median platform 13 consists of a rectangular metal plate. Two first cavities 131 of trapezoidal section extend on its upper side, along its major central axis, near the minor sides. These trapezoidal first cavities 131 are in communication with two second cavities 132 of rectangular section, which occupy part of the trapezoidal first cavities 131. Within each second cavity 132 a cylindrical bar 133 is housed, which spreads along the major central axis of the median platform 13.
One end of each cylindrical bar 133 is blocked on the median platform 13 by means of a nut 134 while the second end is screwed into the thickness of the median platform 13.
The median platform 13 is provided, along its major sides, with perimetral walls 135. Between the lower platform 12 and the median platform 13 two rails 5 are positioned, which extend parallel to the minor axis of the two platforms 12, 13. Each rail 5 includes an L-shaped metal supporting element 51 welded to the lower platform 12, and an L-shaped metal plate 52 welded to the median platform 13. From the supporting element 51 extend two arms, each of which has a rail. The two rails are positioned on the outer sides of the two arms of the supporting element 51. From the metal plate 52 extend two arms with rounded ends. Spheres 53 are housed in the space bounded by the concavities of the rounded ends of the arms of the metal plate 52 and by the walls of the rails positioned on the arms of the supporting element 51. The metal plate 52 can thereby move in both directions with respect to the supporting element 51 sliding on the spheres 53. A spring 54 is fixed to each end of each metal plate 52 and to the lower platform 12. They prevent the translation of each metal plate 52 beyond a certain limit, and restore the median platform 13 to its central position with respect to the lower platform 12 at the conclusion of any movement of the median platform 13.
The upper platform 3 consists of a rectangular metal plate. It has two reliefs 31 of trapezoidal section that lie on its underside, centrally and along its major axis, near the minor sides. The section of the reliefs 31 is complementary to that of the first cavities 131 of the median platform 13. Near the edges of the major sides of the upper platform 3 there are four rollers 32.
The container 2 for waste is fixed to the upper platform 3.
Each hook-release mechanism is fixed on a side of the container 2 for waste. Each hook-release mechanism includes a part 6 fixed to the upper platform 3, a part 7 fixed to the container 2 for waste and a rope 8.
The part 6 fixed to the upper platform 3 includes two hooks 61, rotating on a shaft 62. The two hooks 61 are arranged specularly so as to form a jaw. One end of each shaft 62 is fixed to the wall of the container 2 for waste, while the other end is fixed to a casing 63 fastened to the minor lateral wall of the waste container 2 that extends under its lower base. On the shaft 62, two first sleeves 64 and two second sleeves 65 are inserted. Each hook 61 is joined to a first sleeve 64. Each second sleeve 65 is fixed to a wall either of the waste container 2 or of the casing 63. On each second sleeve 65 a spring 66 is fixed, one end of which is fixed to each first sleeve 64, which is free to rotate on the shaft 62.
The part 7 fixed to the waste container 2 of the hook-release mechanism includes a pin 71, a first plate 72 and a second plate 74. The pin 71 is fixed to the first plate 72. The second plate 74 is omega-shaped and two of its walls are welded to the container 2 for waste. The second plate 74 has two rails 73 on the inner walls and a vertical slit 75 in the central wall. The first plate 72 can move vertically in the rails 73 and the pin 71 slides within the vertical slit 75 of the plate 74. On the central wall is fixed from the outer side a hollow metal cylinder 76, which houses a cylindrical pin 77. Each rope 8 has one double-pointed end. Each of the two points of the double- pointed end is fastened to a hook 61 while the other end of the rope 8 is fastened to a pin 71.
When the container 2 for waste is in resting position, the lower base of the upper platform 3 rests on the base 1, fixed to the ground. The hooks 61 of the parts 6 of the hook-release mechanism are coupled to the cylindrical bar 133 of the median platform 13. When the waste removal vehicle grasps the two lateral pins 71, it causes their upward movement. The movement of the pins 71 causes the upward translation of the ropes 8 and the consequent rotation of the hooks 61 on the shafts 62. The hooks 61 are thereby detached from the cylindrical bar 133 and the container 2 for waste, together with the upper platform 3, can be detached from the base 1.
The waste removal vehicle rotates the waste container 2 of 180° and drops its contents into the same vehicle. To avoid the downward movement of the two lateral pins 71 during this operation, from the two hollow cylinders 76 come out, due to gravity, the pins 77 that are housed therein. The latter go in place under the pins 71, thus preventing their further movement.
It may occur that the approach of the waste removal vehicle to the waste container 2 is not in a perfectly parallel line. In this case the clamping jaws of the vehicle hit one of the two pins 71. The container 2 for waste, the upper platform 3, the median platform 13 and the lower platform 12 then rotate with respect to the frame 11, due to the rotation of the ring 121 of the lower platform 12 with respect to the ring 111 of the frame 11. The container 2 for waste thereupon lines up parallel to the vehicle that can grab also the other pin 71. Subsequently the springs 126 fixed to the lower platform 12 and to the perimetral bars of the frame 11 restore the lower platform 12 and the median platform 13 to their original position.
When the container 2 for waste has to be repositioned on the base 1, the upper platform 3 fixed to the container 2 for waste is brought close to the median platform 13 until the reliefs 31 are inserted in the first cavities 131 of the same median platform 13. The lower base of the upper platform 3 thereby rests perfectly on the upper base of the median platform 13. During the rotation of the container 2 for waste, the pins 77 go back in the hollow cylinders 76 due to gravity.
It is possible that during the approach, the upper platform 3 and the container 2 for waste are not parallel to the median platform 13. In this case the rollers 32 fixed to the upper platform 3 allow its sliding until the major lateral edges of the upper platform 3 hit the perimetral walls 135 of the same median platform 13. At this point of engagement the container 2 for waste is lowered. The pins 71 and the hooks 61 thus restore their original position by means of the springs 66 that force the two sleeves 64 and the hooks 61 fixed thereon to rotate. The opposite rotation of the hooks 61 on the shafts 62 causes the downward translation of the ropes 8 and the consequent coupling of the hooks 61 to the cylindrical bar 133.
The perimetral walls 116 of the frame 11 instead prevent people from reaching under the median platform 13.
The device thus conceived is susceptible to further numerous modifications and variations, all encompassed within the scope of the invention and appended claims. Furthermore, all the details may be replaced by others technically equivalent.
