On the other hand, the object of the present invention has in addition to its recovery and sorting functions, that of compaction under the action of compression means armed by a command.

It is designed to fit into household furniture: Figures 1 and 2 for the main part, figures 3, 4, 5 for its accessories. Its main cabinet 1 can be of square, rectangular or other section. The RTC installed on swivel casters 8, to facilitate all movement, is equipped with a front release door for both bags 12, 14, 23, which is centered around 26, opens by flap on the pedal transverse 10, is locked by 15. The covers 20, of standardized colors, the shapes and curvatures seal the tank, housing the support mechanism for bags as well as the lifting of the latter creating the opening of access to the bags by action on the internal sides, including the shapes of the cutouts 2, allow by pressing on 19, stirrup located at the head of the connecting rod 5, to ensure judicious opening when the transverse pedal 10, 11, is biased by one foot down. At the end of race 49, the lift of 20 is maximum. A device 3, retaining hooks, makes it possible to lock the connecting rod caliper 5 in rear limit switch, permanently stressed by the action of the return springs 13. The individual lifting of each cover or cover can also be carried out using a hand by action upwards on the handles 20 located in the front center of each lid. We see that two actuators allow the lifting of said covers, either by acting on 2 or on the handles of the lids 20. Research in development of the BTI were conducted with the following aim: each sub-assembly should ensure two functions, and conversely, the same function can be generated by two actuators separate, this in order to minimize the number of moving parts composing it. Of these facts, the reliability of the final product is increased and the cost of its mass production reduced. One of the special features of the RTC: two hanging bags 46, 50, on stirrups in 18 19, 46, 47, allow the recovery in the green bag of recyclable products, in the gray bag of waste transformed into thermal energy. Compacting objects recovered: examples of cans (sheet), bottles or containers (plastic) can be done in intervention phases in order to be reduced to a minimum volume, and this at using the additional materials in figures 3, 4, 5, then recovered reduced, but not shredded to facilitate subsequent sorting in a specialized factory. They will be deposited in the green bag or the gray bag, depending on their nature, after opening the corresponding lid 20. Small objects will be introduced into the hole delimited by the two stirrups U-shaped, supporting the 18 male and 19 female bags, fitting into each other figure 6. In the hypothesis or the objects having undergone this first compaction cannot enter through the orifice delimited by 18 fixed support bracket for the bag and 19 mobile support bracket bag at rest in Figure 6, pressing the foot on the pedal 10 causes the backward movement of 19, Figures 7, 47, 50, the maximum opening of the bag is obtained. This pedal has an arm lever on each side of the tank from 10, the ends of which are articulated around two axes supported by fixed stirrups at 7 on the rear part of the tank and linked between them by a transverse front plate 10 covered with a non-slip material 11-48, the everything thus forming a bottom bracket.

The aforementioned equipment: figure 3 support and mechanism seen from the side, figure 5 seen from front face as well as the protective hubcap figure 4 shown positioned Figures 8, 52 are accessories to be fitted on one of the sides of the cabinet or tray main, example on the left in 22.

The pedal 36 placed on an arm 35, articulated at 44, supports systems 38 including the slices 37 serrated squares 57 crush all the bottles 58, bottles in plastic, packs and bricks in hard cardboard ..., which we will have deposited in the open box with a retainer at the base of the rectangular section 33 and this by support out of 36 leading to a reduction result to a quarter of the initial volume. This same pressing action on the pedal 36 can also allow the flattening of any container cylindrical metal (cans) fitted on the two pelican spouts 43 of which the upper has retaining teeth at its end. The casing is carried out according to 42 and 41, simulated dotted boxes in Figure 3 and the flexible pins, retaining springs 40 at rest and 39 pushed back into the work phase. The sheet metal box 55 in figure 9 is flattened by diametral flare of its orifice 56, thereby reducing the volume of the box by 1/2. A return spring 29 returns pedal 36 to the rest position.

The sheet metal boxes, flattened plastic bottles will then be placed in one of the bags placed in the recuperator 1 and will undergo, mixed with other household waste, a second pushing force for compaction using the rectangular perforated flap mobile 4 with the ends raised outwards for non-aggressiveness on the bags during translation movements. This flap is articulated around the 5 'axis mounted on the levers stirrups 5 which undergo the permanent attraction forces of the springs 13 placed in each side and fixed on tray 1.

Weak foot action on the 10-11 pedal retransmitted to 6, twin links with force multiplying effect on the stirrup lever 5 will cause the shutter to recede mobile 4, will facilitate bagging within the recuperator 1 by increasing its openings. Releasing the 10-11 pedal will allow the springs to return and compressions 13 to contract, thus imposing on shutter 4 a permanent thrust on the two bags housed in the bin and being filled. This permanent push will cause additional compaction of the waste stored in the bags. As indicative 9 'and 7 are axes of articulations integral with the tank 1, therefore fixed. 9 and 5 'are floating mobile axes.

The pushing force acting on the flap 4 ensuring the compaction can be five to ten times greater than the action on the pedal 10-11.

The RTC is moved by manual action on the transverse handle 17-21 fixed on the two ends of the arms 16 which themselves are pressed and fixed on the lateral sides of tray 1 at 27. The crankset and pedal 10-11 move in the passage 24 located at the front and fitted in 1 '. The whole rests on the ground at 25.

The axis or bolt support holes 32, 33, 34 arranged in 28 support or the casing figure 4, allow the adaptation of its accessories on the cabinet main 1 '. The lever arms 30 and 31 support the pelican beaks 43, 35 are formed to be offset from the support 28. Viewed from the front, pedals 11 and 36 are located at same level with the ground.

Variant - The COLLECTOR-SORTER-COMPACTOR developed to European standards for kitchen elements figures 11-12-13-14-15-16-17-18-19-20, built-in or not, includes an actuator releasing a pressing member; a means of pressing on the bags so as to open them and the said means applying pressure to the bags, when the actuator is deactivated, FIG. 14.

The kinematics of the pressure means consists of a lever comprising two straight arms 83-84-97 articulated around an axis 98 mounted on a stirrup 66 secured to the lower rear tank; it transmits any motor action on axis 97 supporting rods 96. This axis is located as close as possible to this articulated fixed point 98 and this for multiply the action of the forces applied to the end of said lever, example: pedal transverse 84. The other end of the rods is centered at the top of the right angle 80 of two integral levers 75 located on either side of the tank 65. They each form a square or L.

The short sides of the levers L pivot around the axes 67-82 integral with the sides sides of the tank 65. The long sides of the L-shaped levers have their ends, rods flats 74, bent at 90 °, combine to provide bag support functions, supplemented by clamps 77. Elastic drive means 81 exert forces on all the elements of this kinematics to make it dynamic. Motorized on foot, by action at the end of two parallel arms, by pressing on the transverse pedal 84 the making solidarity - Variants: motor means with pneumatic, hydraulic systems, electromagnetic, all motor means for automation, can replace this transverse pedal 84. The initialization (rest) of the entire chain kinematics can be carried out by elastic actuators springs 81 or any other systems performing the same functions. In the present case two springs 81 centered on the long side of the lever in L 79 and anchored on the front of the lateral sides of the tank 69 perform this function.

These actuators exert on all of this kinematic chain, at rest, permanent compression of the waste bagged by the mobile pusher 76 perforated plate 78 or not, they also raise and lower the covers 58-60 then 57-59 per action on the spoiler 64 resting on 71 and located at the rear of the tank 65 in the upper part, focused in 62 on the stirrup 61. Rollers 63 centered at the head of the spout 64 facilitate sliding for the lifting of 58 and 60. Lifting of 58-60 by 63, then 63 by the retraction of the levers 79 allows greater opening of the bags, because at the front they are held on four fixed flat rods 85-86 and held on four flat rods arranged at the head of the movable lever 73-74.

Small covers 57-59 avoid the use of these actuators when introduced low volume waste, opened and closed manually 56. All types of levers are designed to multiply the forces generated compared to the forces exerted on the compression drive means, springs in the present case.

First volume reduction means for sheet metal boxes, Figures 9-10 and for plastic containers, bottles, packs, etc. by compression for bottles plastics introduced through opening 103 and deposited on the tooth entanglement in comb and scales 106-107 and by stretching for sheet metal boxes introduced by the opening of cover 104; notched lugs 108 exerting in extension and toothed lugs 109, fixed by 110 on the tank 102. The control can be ensured by pedal 112, lever arm 114 focused on 111 of 102, small tank element or any other force generating system.

Clamps 77 hold the bags on the movable flat rods 73-72 and fixed 85-86. When they are full and then closed, whether or not linked by special pliers 115, they are released by the flap of the front door 88, hinged at the bottom 89. A container, removable drawer 99 for recovering possible soiling is slidably mounted at 101 front opening. The plate raised at the front 94-92-93 integral with 90-91, all housed in tanks 65-102.
