Description

The invention relates to safety equipment intended to be installed in a dump, and particularly although not exclusively on a dock of the dump, to allow for example a user located on this dock to deposit garbage in a bucket located below from this platform without risk of falling into this dumpster.

BACKGROUND OF THE INVENTION

In the current dump stations, the user arrives with his vehicle on a dock of the dump whose edge overlooks skips for receiving waste. The user can seize the trash directly in the trunk of his vehicle to throw them in a bucket below this vehicle.

Once these dumpsters are filled, transport trucks load them by accessing an access located below the dock, to get them to a treatment center.

As the waste to be deposited can be bulky and massive, there is a real risk that the user falls from the dock in a dumpster when it deposits its waste. The height of the dock being of the order of two meters, this risk of falling is a real danger. In addition, users can fall into a dumpster when they deposit their waste, but they can also inadvertently fall into a place where there is no grab, as they move along the dock.

To limit this risk, dump piers are generally equipped at each dump location with a folding barrier. When there is no body below, the barrier is raised so that users moving along the dock can not fall. When a bucket is present below, the barrier is instead folded down to allow users to deposit their waste, but without being protected from the risk of falling. Decontamination safety equipment according to the prior art is known to WO 2010/148426 A1 and FR 2 981 966 A1 .

OBJECT OF THE INVENTION

The object of the invention is to provide a solution for protecting users when they drop garbage in a bucket.

SUMMARY OF THE INVENTION

• une position de chargement dans laquelle les deux parois définissent ensemble une ouverture de chargement du réceptacle d'un premier angle d'ouverture qui est dirigée vers l'usager, et
• une position de déversement dans laquelle les deux parois définissent ensemble une ouverture de déversement du réceptacle d'un deuxième angle d'ouverture qui est dirigée vers la face supérieure de la benne pour déverser les déchets dans cette benne.

To this end, the invention relates to safety equipment intended to allow a user to place waste in a bucket, the equipment comprising a support frame and a receptacle having a first wall and a second wall, the receptacle being articulated on the support frame so that the first wall is pivotally mounted relative to the support frame according to a first pivot axis and the second wall is pivotally mounted relative to the first wall according to a second pivot axis, the equipment further comprising means moving the second wall relative to the first wall along the second pivot axis, the support frame, the displacement means and the receptacle forming an assembly comprising stops ensuring that the receptacle is movable between:

• a loading position in which the two walls together define a loading opening of the receptacle of a first opening angle which is directed towards the user, and
• a discharge position in which the two walls together define a discharge opening of the receptacle of a second opening angle which is directed towards the upper face of the bucket to dump the waste in this bucket.

Thus, the receptacle is interposed between the user and the bucket which allows the user to load his waste into said receptacle before tipping to dump this waste in the bucket safely.

For example, if the bucket is below the user, in the loading position, the second wall forms a protective barrier for the user who can not access the bucket and spill position the first wall is in turn a protective barrier for the user by preventing access to the bucket. Thus, the receptacle is always interposed between the user and the bucket which allows the user to load his waste into said receptacle before tipping to dump this waste in the bucket while being protected from falling into the bucket by the receptacle and whatever the position of this receptacle.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the various figures, the dump 1 comprises a platform 2 located at a height of the order of two meters from the ground 3, a trash bucket 4 being here installed on the ground along an edge 5 of this quay which overlooks.

This platform 2 is equipped with safety equipment which comprises a support frame 6 here comprising two fixed feet 7, 8 connected by a base 9 also fixed. Each foot 7, 8 here has an L shape, a first branch 10 extends substantially horizontally to form a lower end of the corresponding foot and a second branch 11 extends substantially vertically to the second branch 10. As for the base 9, it extends here parallel to the edge 5 substantially at said edge 5. The two feet 7, 8 and the base 9 are here mechanically welded elements rigidly secured to the platform 2 having for example their lower ends cast in the concrete of this platform 2, or in a concrete element attached to this platform 2.

The equipment further comprises a tilting receptacle 12 comprising a first wall 13 and a second wall 14. Here, the first wall 13 is mounted movably on the base 9 so as to be pivotable relative to the support frame around a first axis of pivoting AX extending parallel to the edge 5. The second wall 14 is mounted movably directly on the first wall 13 so as to be pivotable relative to the first wall 13 about a second pivot axis B. The two walls are for example made of sheet steel.

The equipment further comprises means for moving the second wall 14 relative to the first wall 13. According to a particular embodiment, said means comprise a pair of cables 15, 16 which are both located between the two walls 13, 14 , the cable 15 being in the vicinity of the foot 7 and the cable 16 being in the vicinity of the foot 8. Each cable is fixed at one end to the first wall 13 between the axis AX and the free edge of this first wall 13 and at the other end fixed to the second wall 14 between the axis B and the free edge of the second wall 14. Said means further comprise a pair of pulleys 17, 18, the pulley 17 being arranged at the top of the second branch 11 of the foot 7 and the pulley 18 being arranged at the top of the second leg 11 of the foot 8. The pulleys 17, 18 are thus integral with the support frame 6. The two pulleys 17, 18 are each pivotable along a third axis of common pivoting C who e st parallel to the axis AX and above said axis. The cable 15 wraps around the pulley 17 and the cable 16 wraps around the pulley 18 so that a rotation of the first wall 13 about the axis AX causes a rotation of the second wall 14 around the axis B regardless of the direction of rotation of the first wall 13.

The feet 7, 8 and the receptacle 12 comprise stop means which limit the amplitude of rotation of the first wall 13 about the axis AX and the second wall 14 about the axis B.

Preferably, the equipment is then arranged so that in a loading position corresponding to that of the figure 1 the two walls are folded V at an angle of about 100 degrees. The two walls then together define a loading opening of the receptacle 12 of about 100 degrees. According to a particular embodiment, the first wall 13 then extends horizontally which facilitates the loading of the receptacle 12 for the user. The second wall 14 is inclined relative to the first wall 13. The first wall 13 extends here about fifty centimeters from the ground which further facilitates the loading of the receptacle.

Preferably, the equipment is further arranged so that in a dumping position corresponding to that of the figure 2 , the second wall 14 extends towards the upper face of the bucket 4 when the receptacle 12 is in the discharge position, the first wall 13 then extending substantially in the extension of the second wall 14. The two walls define then together a discharge opening of the receptacle of about 180 degrees which greatly facilitates the tilting of waste out of the receptacle 12.

The receptacle 12 is thus movable between a loading position corresponding to that of the figure 1 , in which its main opening is directed towards the platform 2, and a dumping position corresponding to that which it occupies in the figure 2 and in which its opening is instead directed downwards towards the upper opening of the bucket 4.

A user arriving with his vehicle on the platform 2 to deposit waste can immobilize his vehicle near the receptacle 12 in the loading position. The user can then easily move the waste from the trunk of his vehicle to the receptacle 12 to place on the first horizontal wall 13 of this receptacle, since the difference in height is small between the first wall 13 and the ground.

This waste, which is marked 19 in the figures, is thus supported by the first wall 13 and bears against the second wall 14 of the receptacle 12.

When the user has deposited all the waste, it then tilts the receptacle 12 from its loading position of the figure 1 towards his spill position of the figure 2 to drop all waste 19 in the bucket 4, as schematically illustrated in the figure 2 .

As clearly visible in the Figures 1 and 2 when the receptacle 12 is in the loading position, as well as when it is in the dumping position, its two walls 13, 14 have in both cases a sufficient height, of the order of one meter, to constitute a effective obstacle to protect the user from a fall in the bucket 4 (the second wall 14 in the case of the loading position and the first wall 13 in the case of the spill position).

According to a particular embodiment, the tilting of the receptacle 12 between its loading position and its discharge position is assisted by a pair of jacks 20 and 21 which are both located under the first wall 13, the jack 20 being in the vicinity foot 7 and the cylinder 21 being in the vicinity of the foot 8.

Each jack 20, 21 has one end articulated to the base 9, and its other end articulated to the first wall 13, between the axis AX and the free edge of this first wall 13. Preferably, each jack 20, 21 is hinged at the first wall 13 substantially at the fixing of the cable corresponding to the first wall 13.

Under these conditions, the retraction of the cylinders 20 and 21 makes it possible to turn the receptacle 12 towards its loading position to which it stops by means of abutments, and the deployment of these cylinders 20 and 21 makes it possible to turn the receptacle 12 towards its dumping position to which it stops in support on other stops.

Naturally, the invention is not limited to the embodiment described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.

In particular, although here safety equipment is installed on a dump dock to allow a user to place waste in a bucket that this platform overhangs while providing protection against the fall of the user in this bucket, the safety equipment may be installed directly on the ground or on a dock to allow a user to place waste in a bucket overhanging said floor or said wharf without the user having to climb or cling to the dumpster to dump directly waste or throw directly into the dumpster. The receptacle may thus be a lifting receptacle. The receptacle may be arranged on the frame so as to translate in a substantially vertical movement relative to the frame between a low location in which the receptacle is at the level of the user and a high location in which the receptacle is at the level of the receptacle. opening of the bucket. Thus, in the loading position and in low position, the receptacle will be at the user level and turned towards the user which will allow the user to deposit his waste in the receptacle. In spill position and high location, the receptacle will allow the dumping of waste in the bucket. In addition, the receptacle will always be interposed between the user and the bucket which will limit the access of the bucket to the user providing additional protection for the user.

In addition, although here the actuating means comprise two cylinders, the actuating means may comprise a different number of actuators or other types of actuators. The actuating means may thus comprise a single jack articulated at one end to the support frame and at another end to the first wall. The cylinder or cylinders may be hydraulic cylinders associated with a micro-hydraulic, or electric cylinders. The actuation means may be controlled by the user as well as by a management manager of the waste, since for example a control unit.

Similarly, although here the displacement means comprise two pulleys and two cables, the moving means may comprise a different number of elements or other types of elements than those illustrated. For example, the displacement means may comprise a single cable attached at one end to the first wall and at another end to the second wall and a single pulley arranged on the support frame so as to guide the cable from the first wall to the second wall. The term cable here designates any flexible component of solid or tubular section of circular shape, flat or other and slightly extensible such as a belt. The displacement means may comprise actuators for causing in a controlled manner the tilting of the second wall relative to the first wall.

Although here the two walls are hinged together and the first wall is articulated on the frame, the two walls can be simply articulated both on the frame. The first pivot axis and the second pivot axis can be merged.
