Description

Automatic opening and closing device for trash bins.

Object of the invention

The present invention relates to a device which allows the automatic opening and closing of a container of garbage, of which they are usually located on public roads and of those that incorporate a hinged lid to the complementary body, as a closing element for the mouth of the latter.

The object of the invention is to achieve that the bucket closure situation occurs automatically, by the coupling of the cover to the mouth of the body, leaving said lid locked while the opening maneuver is performed also automatically, by gravity, when the container during its emptying maneuver.

Background of the invention

Conventionally the cubes or containers of garbage do not have more than means to ensure more closure or less tight to prevent the exit of bad odors abroad, but they lack lock means that prevent the accessibility inside it, which brings with it a side that in many occasions the users leave the lid of the container, and on the other that unwanted manipulations occur in inside, trying to recover discarded objects that for third parties they may have a certain value, which means in practice the presence of garbage bags in front of the container, outside of it, which even on many occasions are open, with the consequent and negative repercussions environmental.

Trying to ignore this problem are known garbage bins that instead of being provided with a lid folding it is a sliding cover, sliding type, assisted by elastic means that automatically tend to the situation of closing it, and blocking elements that immobilize said cover in closing situation.

In this sense, the German patent DE 100 19 925, in which a retainer device for a Sliding lid of a movable trash container and that can be emptied automatically by means of a transport vehicle of garbage, a solution that besides being limited exclusively to containers with sliding lid, is intended to hinder the lid manipulation, preventing such manipulation from being carried out by children, with the consequent risk of accidents, but it can be manipulated by any adult, and in fact it is designed to be, so the problem is not solved previously mentioned of improper manipulations inside the container trying to find reusable objects.

The obvious solution to the exposed problem is provide the container with a lock mechanism with key, of so that its interior is not accessible through the lid, establishing in the latter or more mouths for deposition of waste, a solution that already exists in practice. However, such solution presents as a fundamental problem the need to act on the lock mechanism when the emptying or unloading of the container, which slows down The collection operations are very considerable.

Description of the invention

The device proposed by the invention resolves in a fully satisfactory way the problem previously exposed, in the different aspects commented, also allowing its application to containers with hinged lids.

Specifically said device allows a automatic closing in the swinging maneuver of the lid towards the closing situation, blocking said lid in such closing situation, preventing the opening of the container under any circumstances and when it is conveniently seated on the ground, but ensures that the mechanism is unlocked, by effect gravitational, when the container undergoes a flip maneuver while downloading it.

To do this and more specifically said device materializes in the functional combination of two elements, intended to be fixed respectively to the body and the container lid, preferably in opposition to its axis hinge, incorporating the upper element, mounted on the cover, a locking pin, while the other incorporates a complementary, tilting hook, assisted by a spring that tends to swing said hook towards the blocking situation on the pin.

A special configuration for these elements allows the closing situation to be reached automatically, sliding the pin over the front of the hook, swinging to the latter, until reaching the blocking situation, which automatically set by the effect of the spring that is attended by hook.

As a complement to the structure described in the lower element houses a counterweight that finishes one of the ends of an arm articulated jointly to said casing element at its other end, and equipped in its middle area with a stop acting on the hook, all so that in situation normal support of the container on the ground the aforementioned counterweight it is inoperative, while when the turn of the container, the counterweight balances by gravity and in such movement of tilt acts through its stop on the hook, forcing him to move, that is, to swing, towards the situation of  unlocking with respect to the complementary pin.

Preferred Embodiment of the Invention

In view of the figures outlined and especially of Figure 1, can be seen as the closing device that the invention proposes has been provided for garbage containers in which a body (1) participates to whose mouth it joins hingedly a closing cover (2), provided with holes, windows, chimneys or any other means for deposition of waste inside, without the possibility of direct access to it, and it is materialized in two elements (3) and (4), the first one destined to fix internally to the mouth of the body (1) and the second to also be fixed internally to the perimeter skirt of the cover (2), in a situation of confrontation.

Inside the element (3) is housed a hook (5) that emerges outwardly from it upwards, pivotally mounted on a transverse axis (6) and assisted by a spring (7), mounted in turn on the shaft itself (6), so that said spring tends to swing the trigger (5) towards a blocking limit situation, the one shown in figure 3, in which the anterior and free end of the hook (5) is locked in a pin (8) operatively established inside the element (4) associated with the lid, element with an opening in its end bottom (9) to allow penetration of the hook (5).

Within the lower element (3) a counterweight (10) that ends one of the ends of a cranked arm (11), which is articulated jointly at its other end (12) to the own housing of the element (3), incorporating said arm (11), in its middle zone, a stop (13) that in the normal position of the container is located laterally and adjacent to the hook (5), without act on the latter, but when the container invests its position, during the emptying maneuver thereof, by effect gravitational weight (10) and as seen in Figure 5, acts on the hook (5) causing it to tilt in sense of unlocking

In order that the emerging sector of the hook (5) with respect to element (3) cannot constitute a danger, has planned to be housed in a recess (14) of said element (3), in which it is likely to engage tongue and groove, in a closed situation, a bulge complementary (15) of which the element (4) associated with the cover and on which the pin (8) is located, as seen in any of figures 3 and 5.

According to this structuring and from the opening situation for the container shown in figure 1, when the cover (2) tilts towards the closing situation, the pin (8) affects the inclined plane (16) defined in the limb outside and free of the hook (5), forcing the latter to swing against the dock (7), up to a limit situation in which said pin (8) faces the side recess (17) of the hook, at which time it recovers its primitive position of blocking, by effect of said spring (7), and in which the cover (2) is fixed immovably to the body (1) in this situation the opening the lid (2) is impossible, keeping the container in normal working position, resting on the ground, while when the emptying maneuver of the container, when inverting the device its position, and specifically by reversing its position the lower element (3), the counterweight (15) passes from the position shown in Figure 3 to that shown in the Figure 5, by effect of gravity, so that in this tilt movement of your arm (11) the stop (13) drags the hook (5) towards the unlocking situation shown in said Figure 5, passing said counterweight automatically back to the inoperative situation, when the container in turn recovers from Again your work position on the ground.
