Abstract:
This invention relates to improvements in refuse bins incorporating compacting means for domestic use, wherein the compacting plate comprises two upwardly oriented tabs which are placed in housings in the lid to be slidably associated with a control member. Catches facing opposite each other and borne by said tabs come into slides in the control member embedded in a groove in the lid. In this way, by subjecting the control member to a translation, it may, at the end of a stroke, be pivoted with respect to the catches in order to orient it vertically with a view to vertically actuating the compacting plate.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to improvements in refuse bins incorporating compacting means, for domestic use. 
     2. History of the Prior Art 
     FR-A-2 135 322 discloses a refuse bin of the type in question, comprising: 
     an upwardly open bin; 
     a lid articulated on the bin; 
     a compacting plate disposed inside the bin and comprising two upwardly oriented tabs which pass through the lid and comprise means for sliding and pivoting association with the manoeuvring rod which rests on the lid. By subjecting this rod to a translation, the latter may, at the end of stroke, be pivoted with respect to said means of the tabs in order to orient it vertically with a view to actuating the compacting plate downwardly and upwardly. 
     However, the position of the manoeuvring rod on the lid is neither practical nor aesthetic. 
     Moreover, assembly of the low end of the manoeuvring rod and of the compacting plate necessitates a pusher system controlled by a handle, the whole being complex and uneconomical. 
     SUMMARY OF THE INVENTION 
     It is an object of the improvements according to the present invention to overcome these drawbacks and to allow a compacting refuse bin to be produced which responds better than heretofore to the desiderata of the users. 
     To this end, the tabs of the compacting plate come, in high position of the latter, into housings in thc lid opcning out in a longitudinal groove made in the top of the latter and which slidably contains thc plate controlling member so that the catches come into this groove and penetrate in known manner in two longitudinal slides made in the two opposite longitudinal faces of the control member. 
     According to another feature of the invention, the slides of the plate control member comprise two notches thanks to which the catches of said plate may be engaged in these slides in a position thereof which is never presented during operation. 
     According to another feature of the invention, the active end of the plate control member comprises a depression in which a fixed projection on this plate penetrates in order to lock the member perpendicularly to the latter and be automatically released as soon as the member is pulled upwardly.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings, the refuse bin illustrated in FIG. 1 essentially comprises a bin 1 of rectangular cross section of which the upper part is covered by a frame 2 on which is articulated a lid 3, whilst, inside this bin, a compacting plate 4 may be displaced vertically with a view to compressing the refuse contained in a plastic bag. The latter is disposed inside the bin and its opening is wedged between the frame 2 and the upper part of bin 1, as illustrated in FIG. 2 et seq., the bag being referenced 5 and shown schematically in broken lines. Openings 1a and 2a are made in register in the bin and the frame respectively, so that, by passing his hands through these openings, the user grips these two elements without separating them. 
     As illustrated in FIG. 1, the compacting plate 4 is adapted to be associated with a control member 6 which is normally, i.e. not during periods of compacting, located in a groove 3a in the lid 3. The latter pivots with respect to frame 2 via pins 2b on the latter which engage in perforations 3b made in lugs 3c on lid 3. 
     It is observed that groove 3a is traversed by an opening 3d located at the centre thereof and which is intended, on the one hand, for the passage of the control member 6 during compacting and, on the other hand, to allow permanent assembly of this member and of the compacting plate 4. 
     The 1atter comprises a network of reinforcing ribs issuing from a central vertical extension composed of two vertical tabs 4a, 4b of which the opposite faces each bear a catch 4c, 4d comprising a common horizontal geometrical axis. Between the two tabs 4a and 4b is located a hollow projection 4e whose role will be set forth hereinbelow. 
     The control member 6 is in the form of a rectangular parallelepiped whose length corresponds to that of lid 3 and whose section is identical to that of groove 3a (FIG. 2), with the result that this member is embedded in the lid. One of the ends of member 6 comprises a downwardly projecting gripping handle 6a which engages in a hollow 3e made at one of the ends of groove 3a. In this way, as will be emphasized hereinafter, the outward slide of member 6 in groove 3a can only be effected in the direction of arrow F of FIG. 5. Member 6 further comprises an opening 6b adjacent handle 6a and facilitating gripping thereof. The two longitudinal faces of member 6 are hollow so as to determine two slides 6c, 6d whose height is slightly greater than the diameter of catches 4c, 4d. The end of member 6 opposite its handle 6a is provided with a depression 6e of section complementary to that of projection 4e of the compacting plate 4. 
     FIG. 4 illustrates the refuse bin according to the invention in a partial plan view, its lid 3 being open as illustrated in discontinuous lines in FIG. 3, i.e. it has been pivoted about pins 2b of frame 2, so that its rear edge 3f comes into abutment against the corresponding face of the frame so as to constitute stop of maximum opening. In this position, the control member 6 is introduccd horizontally in the opening 3b in the lid, so that it is presented horizontally once its handle 6a abuts against thc top of said lid. As the two slides 6c, 6d of member 6 each comprise a notch 6f, 6g, if the compacting plate 4 is presented in vertical position with its tabs 4a, 4b turned towards notches 6f, 6g, catches 4c, 4d may be made to penetrate in slides 6c, 6d further to the position of notches 6f, 6g. Arrangements are such that, in no position of the control member 6 during operation do the catches 4c, 4d ever come to the level of notches 6f, 6g. In fact, once said catches are engaged in slides 6c, 6d of member 6, any axial displacement of the latter is made in the zone included between these notches and its end opposite handle 6a. It is noted in particular on this subject that member 6 cannot be displaced in the direction opposite that of arrow F of FIG. 5 beyond the position of abutment of the handle 6a against the hollow 3e. The catches are then made to slide in slides until they come into abutment against end stops 6h, 6i of the slides opposite handle 6a (FIG. 6), then the plate is pivoted so that it is oriented perpendicularly to its manoeuvring member 6 (FIG. 6). The manoeuvring member is then withdrawn outwardly by sliding it in opening 3d in lid 3 until plate 4 comes against the underneath of lid 3. The opening 3d of the lid comprises two lateral cut-outs 3g, 3h by which open out into groove 3a two housings 3i, 3j into which come tabs 4a, 4h in high position of the plate 4, the catches 4c, 4d then being crosswise in said groove whilst being engaged in the slide of member 6, as illustrated in FIG. 3. In this way, an articulation is constituted between this member and plate 4. Finally, the lid is closed and the control member 6 is folded down to the horizontal with respect to plate 4, so that it rests in groove 3 a in the lid. The latter is displaced axially until it no longer projects from said lid, the handle 6a cooperating with the hollow 3e. The refuse bin is then in rest position, i.e. not in use. 
     If a user desires to place refuse in the bin, it suffices to open the lid, pour the refuse into bag 5, and to close the lid again. If he then desires to compress the products deposited in the bag, he extracts the manoeuvring member by subjecting it to a longitudinal translation in the direction of arrow F of FIG. 5, such translation bringing the two catches 4c, 4d to near the end of the member 6 opposite its handle 6a. Under these conditions, it is possible to pivot member 6 to bring it to the vertical in the direction of arrows Fl and F2 of FIG. 5. The following operation consists in vertically lowering the manoeuvring member downwardly in the direction of arrow F3. When plate 4 comes into contact with refuse, it is immobilized whilst member 6 may be descended a little more in order to engage the projection 4e of this plate in the depression 6e of the manoeuvring member 6 (FIG. 7). In this way, the angular positions of these two elements are locked and compacting may be practised without pivoting the plate 4. 
     Return into position is effected in reverse. When the member 6 is withdrawn by a vertical displacement, tabs 4a, 4b of the plate come into housings 3i, 3j of the lid against the bottom of which they abut in order to allow disengagement of the projection 4e with respect to the end depression 6e of the member 6. The latter returns into the position illustrated in FIG. 2, so that it may again pivot with respect to catches 4c and 4d in order to be placcd in horizontal position in the groove 3a  of the lid. This member is then returned into its rest position by sliding in the direction opposite that of arrow F of FIG. 5. 
     A compacting refuse bin has thus been produced of which the compacting plate is actuated by a control member which, in rest position, is perfectly included within the general volume of the bin. 
     It goes without saying that the article forming the subject matter of the present invention may be made of any appropriate materials, but that its different elements are advantageously made by moulding a plastics material under pressure. 
     It will be noted that the handle 6a abuts against the bottom of groove 3a if the manoeuvring member 6, placed vertically, is released by the user when the bin is empty. 
     It must, moreover, be understood that the foregoing description has been given only by way of example and that it in no way limits the domain of the invention which would not be exceeded by replacing the details of execution described by any other equivalents.
