Description

Waste column

The present invention relates to the technical field of waste columns or selective sorting containers.

Known waste columns include an opening hatch in the lower part allowing waste to be evacuated.

In order to ensure the opening and closing of the hatch of the column or of the waste container, it is known to employ devices with a rigid rod of the Kinshofer type connected, via a spreader bar or another form of internal structure, to tie rods themselves connected to the hatch, which is articulated around a hinge.

However, with such systems, in the event of poor handling of the column, for example when it is simultaneously lifted and moved laterally, the rigid rod can twist and therefore no longer slides in its guide.

It is known to replace this rigid rod with a chain to allow movement. If this solution responds well to the problem, it implies that the spreader bar or part of the internal structure can then move laterally in the column and can thus abut against the walls and damage them.

In order to solve this problem, the present invention relates to a waste column comprising an outer casing forming an upper wall, a lower wall and a side wall, and a fixed internal supporting structure, at least one hatch located at the level of the hinged lower wall around at least one hinge to the fixed supporting structure, and a hatch maneuvering member provided at the level of the upper wall and connected to the hatch by a transmission member.

According to the invention, the transmission member further comprises a guide element able to pass through at least partly the fixed internal structure of the column. This guide element makes it possible to hold the transmission member in a given direction and thus avoids any movement inside the column.

According to one characteristic of the invention, the transmission member comprises at least one chain and/or a cable comprising one end connected to the maneuvering member and one end connected to the guide element. The implementation of a flexible element for the transmission component makes it possible to guarantee freedom of movement and thus to reduce internal stresses linked to the repetition of the opening and closing movement of the hatch.

According to another characteristic of the invention, the guide element comprises a guide tie rod. Such a guide rod or needle makes it possible to handle the column by keeping the hatch in the closed position. This solution is inexpensive, easily implemented and not very inconvenient for the operation and the size of the column.

According to yet another embodiment characteristic, the guide element is able to pass through the fixed internal structure of the column at the level of the maneuvering member. Such an arrangement ensures the centering of the transmission member. Other non-centered guidance systems can be implemented depending on the shape of the maneuvering device and its arrangement within the internal structure of the column.

According to one embodiment of the invention, the transmission member comprises at least one rigid tie rod connected on the one hand to the guide element and on the other hand to the hatch.

According to a variant embodiment of the invention, the transmission member comprises a crossbar connected on the one hand to the guide element and on the other hand to at least one rigid tie rod connected to the hatch. The implementation of a spreader facilitates the design of the column, in particular when it includes two hatches.

According to one embodiment of the invention, the operating member comprises a Kinshofer mushroom or a double hook system.

According to one embodiment of the invention, two hatches are implemented.

Of course, the different characteristics, variants and embodiments of the invention can be associated with each other in various combinations insofar as they are not incompatible or exclusive of each other.

In addition, various other characteristics of the invention emerge from the appended description made with reference to the drawings which illustrate non-limiting forms of embodiment of the invention and where:

is a perspective view of an embodiment of a column according to the invention,

is a perspective view of a detail of a column according to the invention in the closed hatch position with the guide element visible through transparency of the internal structure of the column, and

is a perspective view of a detail of a column according to the invention in the open hatch position.

It should be noted that in these figures the structural and/or functional elements common to the different variants may have the same references.

A column according to the invention as illustrated in is designated as a whole by the reference 1. The column 1 comprises an outer casing 2 forming an upper wall 3, a lower wall 4 and a side wall 5. The outer casing 2 of the column 1 is represented in transparency on the , the outer casing 2 is no longer shown in the following figures.

On the , the outer casing 2 is substantially parallelepipedic in shape. Other shapes are compatible such as a cylindrical shape. The outer casing 2 comprises plastic materials and/or composite and/or metallic materials and/or comprises wood. Other compatible materials may be used. The outer casing 2 of the waste column 1 according to the invention is capable of containing waste of the household waste type, bottles, glasses and other household waste, from professional or industrial activity.

Column 1 comprises a fixed internal structure 6 included in the outer casing 2 formed by elements connecting the upper wall 3 to the lower wall 4.

According to the embodiment illustrated in , the internal structure 6 of the column 1 comprises in particular elements fixed to one another connecting the upper wall 3 to the lower wall 4.

In order to ensure its main functions, the column 1 comprises, at its lower wall 4, a hatch 10 able to move between an open position and a closed position. Column 1 can thus pour its contents into a container provided for this purpose. According to the embodiment visible at , two hatches 10 are implemented each comprising a frame 11 connected to the internal structure 6 at the level of the lower wall 4 by means of two hinges 12. The number of hinges 12 is adapted according to the dimensions of the column 1 and the used materials. A hatch 10 of a column 1 according to the invention comprises a panel (not shown) made of a suitable material in order to close the lower wall 4 of the column 1.

According to other embodiments not shown, a column 1 comprises a single hatch 10.

Each hatch 10 moves between a closed position and an open position thanks to an operating member 20 located at the level of the upper wall 3 of the column 1. In a preferred but non-limiting embodiment, the operating member 20 comprises a Kinshofer 21 mushroom or a double hook system. The Kinshofer mushroom 21 or double hook system makes it possible, in a secure manner, on the one hand, to control the opening and closing of the hatch or hatches of the column 1 thanks to the implementation of a first washer 22 , and on the other hand, to seize, lift and independently handle the column 1 thanks to the use of a second washer 23. To do this, the Kinshofer mushroom 21 is mounted on a vertical tube 24 integral with or included in the internal structure 6 at the level of the upper wall of the column 1.

To operate the hatch 10, the column 1 further comprises a transmission member 30. The transmission member 30 makes it possible to ensure the command given by the maneuvering member 20 and thus to open or close the hatch or hatches. 10.

To do this, the transmission member 30 comprises a portion of chain 31 connected in particular to the operating member 20, the Kinshofer mushroom 21 according to Figures 1, 2 and 3.

In a variant embodiment not shown, the transmission member 30 comprises at least one cable. Other alternative embodiments may include mixed chain and cable solutions. And, other flexible and/or elastic means can be implemented to ensure the transmission of the desired movement.

The transmission member 30 also comprises at least one rigid tie rod 32 connected to the hatch 10. According to the embodiment illustrated in , the column 1 comprises two hatches 10, each connected to a rigid tie rod 32. A pivot connecting element 33 makes it possible to ensure the pivoting movement between the rigid tie rod 32 and the hatch 10. According to the illustrated embodiment, each tie rod rigid 32 is thus connected to a through bar 34 of the frame 11 of each hatch 10 via two fixing plates 35 crossed by a rigid rod providing the pivot connection between the rigid tie rod 32 and the hatch 10. Other technical solutions can be implemented. implemented to ensure the opening and closing of each hatch 10. For example, a more complex structure of successions of rigid tie rods 32 can be implemented. The pivot connecting element 33 can also be fixed directly to the frame 11 of the hatch 10. The pivot connecting element 33 can also be fixed to an extension of the frame 11 of the hatch 10.

According to the illustrated embodiment of a column 1 comprising two hatches 10, the two rigid tie rods 32 are connected to a crossbar 36. In order to guarantee a substantially fluid movement for the transmission member 30, each rigid tie rod 32 is fixed to the lifter 36 by means of a pivot connection. This embodiment is not limiting.

According to a variant embodiment with a single hatch not shown, the transmission member 30 can be simplified. According to one embodiment, the lifter 36 is not necessary.

According to the invention, the column 1 further comprises a guide element 40 of the transmission member 30 able to pass through at least partly the fixed internal structure 6 of the column 1.

On the , the guide element 40 comprises a guide tie rod 41 capable of collaborating with the vertical tube 24 of the internal structure 6 of the column 1. The guide tie rod 41 of longitudinal shape in fact comprises dimensions allowing it to fit into the vertical tube 24 on which the maneuvering member 20 is mounted.

The guide tie rod 41 is therefore fixed, on the one hand, to the chain 31, and, on the other hand, to the crossbar 36. On the , the guide tie rod 41 is retracted into the vertical tube 24, the hidden part is visible through the transparency of the vertical tube 24.

According to an embodiment not shown, the guide tie rod 41 is directly connected to the hatch 10.

The lengths of the portions of the chain 31 and of the guide tie rod 41 are chosen so as to optimize the compromise between guide portion and flexibility of the suspension.

To maneuver the invention, column 1 is gripped and lifted by means, for example, of a crane truck whose arm is fitted with a gripper specially designed to lift and empty column 1.

For these purposes, the hydraulic gripper comes into engagement with the Kinshofer mushroom 21 so as to lift the column 1 while maintaining the hatch 10 in the closed position. The illustrates the detail of the top of column 1 when the hatch 10 is in the closed position. For the hatch 10 to be in the closed position during handling of the column 1, the upper washer 22 of the maneuvering member 20 must thus be kept in the high position.

Column 1 is then directed towards a collector, then the gripper collaborates with the Kinshofer mushroom 21 so as to release the chain in order to open the hatch 10. Thus for the hatch 10 to be in the open position, the upper washer 22 of the operating member 20 must be in the low position. The illustrates the detail of the top of a column 1 according to the invention when the hatch 10 is in the open position.

Other maneuvering methods of the invention are possible with a device capable of collaborating with the maneuvering member 20 of the column 1 according to the invention.

It should be noted that when the column 1 is not in motion, other means are implemented in order to keep the hatch 10 closed. For example, simply by gravity when column 1 is placed on hard ground.

Of course, various other modifications may be made to the invention within the scope of the appended claims.
