Abstract

Pressing device (1) for waste products such as, for example, packing material in a container (2) with a pressing tool (7) articulated with a supporting part (6) and articulated through a connection rod (13) with a hand lever (10) that is articulated with the supporting part (6) above the pressing tool (7). The connection rod (13) is articulated on one side with the pressing tool (7) and on the other with the hand lever (10) to form a knee lever with the lever arm (17) of the hand lever (10) defined between the two articulation points (9, 14). To perform compacting by immersion of the pressing tool (7), the latter projects forwards from below in the operating position with a, for example, folding or shiftable, pressing part (18) relative to an articulation plane (8') passing through the articulation axis (8) of the pressing tool (7).

Description

 Pressing device

The invention relates to a pressing device for waste material accommodated in a container, having a pressing device articulated on a bearing part, which is connected to a hand lever which is articulated above the pressing device on the bearing part via a connecting rod which is articulated on the one hand on the pressing device and on the other hand on the hand lever is and together with the lever arm of the hand lever defined between the two articulation points essentially forms a toggle lever.

From EP 648 692 AI such a pressing device is known, which is integrated in the associated container. The known container with an integrated pressing or compacting device is intended in particular for compacting film-like waste material, as is the case in the form of packaging material, e.g. in large quantities in factories, and it has proven itself very well for this purpose, since the container can be brought in and used in the factories. The toggle actuation for the press device designed as a press cover enables effective force conversion, the compression process being initiated efficiently when the press cover is initially swung down from a relatively steep, swiveled-up position. In this context, it is necessary in the known container, the press cover as well as the hand lever at a relatively large distance from the upper edge of the container down to the container rear wall, whereby the space in the container can be used insufficiently. In this respect, the known device is still in need of improvement in order to achieve optimum utilization of the container height and, in connection therewith, an even higher degree of compression. It would also be desirable if the pressing device could be used independently of the respective container designs, in order nevertheless to achieve a corresponding pressing depth, i.e. a correspondingly large compression stroke.

Compression with the aid of a toggle lever assembly is also important since, as mentioned, only a small amount of force is required for the compression. In this respect, lever presses such as those described in US 492 259 A are unsuitable: the press known from this US 492 259 A is a citrus press, with simple lever actuation being unproblematic because lower forces are necessary from the start, compared to pressing devices for compacting waste material in comparatively large collecting containers, which for example can have a height of approximately 150 cm and a cross-sectional area of, for example,% m ² or more.

A lever actuation in a collecting container is also shown in EP 6 242 AI, where the introduction of paper waste or the like is also shown through a funnel provided in the container lid with the aid of a plunger attached to the hand lever. This known arrangement would also be used to compress larger volumes of packaging materials, e.g. of cardboard materials, hardly usable.

It is now object of the invention to provide a pressing device ^• the initially defined kind, which still ensures effizi¬ duck compression due to the toggle actuator, but also allows the viewer to immerse the press organ in the container. The press device should be accessible for efficient use regardless of whether it is fixedly attached to a container, detachably placed on a container or attached to an independent holder, for example on a frame or on a wall bracket.

The pressing device according to the invention of the type mentioned at the outset is characterized in that, in the operating position, the pressing device projects downward with a pressing part, for example a fold-out or displaceable pressing piece, relative to a hinging plane through the articulation axis of the pressing device.

In the pressing device according to the invention, the actual pressing plane, the underside of the pressing part, is thus displaced downwards in operation relative to the articulation plane, the pressing part being able to dip correspondingly deep into the respective container in order to achieve the desired compression effect. Nevertheless, the toggle lever arrangement enables the pressed part to be swiveled up sufficiently with its underside, so that the container can be filled with the waste material to be compacted, such as packaging material, up to its upper edge. before the compression process takes place. Following such compacting of waste material in the container, the pressed part can be pivoted up again to enable refilling of waste material, after which this refilled waste material is compacted again. The press part which can be inserted comparatively deep into the container in the operating position can be achieved by choosing a fold-out or displaceable or extendable design of the press part, but it can also be of a correspondingly deep design, with an upper one, articulated on the bearing part and with the hand lever connected via the connecting rod support part, for example, over rods, connected, frame-shaped, lattice-shaped or plate-shaped pressed part.

In order to enable targeted control of the material flow during compaction, it has proven to be particularly advantageous if the downward-pivoting, lockable in the pivoted-out position, e.g. lattice, plate or frame-shaped pressed part on the underside of e.g. frame, lattice or plate-shaped, articulated on the bearing part is articulated. In the end position of this press device, the swung-out press part is thus in an inclined position, the articulation of the press part on the support part in the front region, on the end of the support part remote from the articulation point on the bearing part, or else adjacent to the articulation point on the bearing part. Such a swiveling press part also offers the possibility of achieving a compact, space-saving arrangement of the press device when it swings in. Furthermore, in this retracted or folded position of the pressed part, the final compaction of the refilled waste can be accomplished in a particularly advantageous manner, with the container completely filled.

In order to couple the swiveling press part in the swiveled-out position as rigidly as possible with the support part, it is furthermore favorable if the press part is connected to the support part via at least one locking strut. The locking strut can enable locking in different swivel positions of the pressed part, for example by inserting a coupling pin into a hole in a row of holes. A particularly easy to use arrangement is but can be achieved in that the locking strut is an articulated strut, the strut arms of which are articulated on the supporting part or on the pressing part, and which can be fixed in the extended position.

If, on the other hand, an inclined position of the pressed part in the operating position is not desired, for example in order to achieve uniform compression in the container over the entire cross-sectional area of the container, it is also advantageous if the e.g. plate, lattice or frame-shaped pressed part on the underside of e.g. Frame-shaped, lattice-shaped or plate-shaped, pressed-organ support part which is articulated on the bearing part and is telescopically extendable or is displaceably attached via at least one pair of articulated struts, the articulated struts being fixable in the unfolded extended position. With regard to the final compaction of refilled waste material, in the folded state of the pressed part, it is advantageous if the articulated strut of the pair are arranged so that they can be folded in opposite directions. With such an arrangement of the articulated struts they remain in the collapsed state within the boundary defined by the pressing device and thus within the container cross section.

For simple handling, it is advantageous if, in order to fix the or each articulated strut in its extended position, a pin is provided, which can be plugged or inserted into the articulated interconnected strut arms by means of eyelets or sleeves aligned in the extended position. Furthermore, it is also favorable here for fixing the articulated struts in the folded-up state if an eyelet or sleeve is attached to the supporting part for fixing the or each articulated strut in the folded-up state of the pressed part and the articulated strut (s), this eyelet or sleeve having a the eyelets or sleeves of the folded up strut (s) are aligned.

As already mentioned above, the present pressing device can be used advantageously in various containers, the good compression effect nevertheless being ensured. The containers can also have different cross-sections, and in order to achieve the desired compaction results here with one and the same pressing device, it is furthermore particularly advantageous if the pressing part can be extended with a Larger part is equipped. In a corresponding manner, it is also advantageous if the pressing part is equipped with at least one enlarging part which is articulated on one of its edges and can be folded over by 180 °.

Instead of an extendable or fold-out press part, this can also be designed from the outset with a corresponding overall height in order to ensure the desired deep penetration into the collecting container, and it is therefore particularly advantageous according to the invention if the press part is formed by a press box. In view of the simple manufacture of the individual components, it is advantageous if the press box is hinged to a bearing part, e.g. plate, lattice or frame-shaped support part is attached. The attachment can in particular be releasable, for example with the aid of threaded bolts.

On the other hand, in order to build up the pressing device with as few individual parts as possible, it is also advantageous if the press box forms a one-piece unit which is articulated with a flange-like extension on the bearing part.

Depending on whether the associated container has a square or round cross-section, if an optimal adaptation of the press box in its outer shape to the container is desired, the press box can be cylindrical, truncated cone-shaped, prismatic or truncated pyramid-shaped. A bevel on the back, as e.g. with a pyramid-shaped or truncated cone-shaped press box provides the additional advantage that the material flow during compression can be better controlled towards the rear of the container for optimal use of the space in the container.

As has already been explained, the present pressing device can advantageously be made available independently of the respective containers, it then being possible for the application to simply attach the pressing device to the upper edge of the respective container. Accordingly, it is favorable if the bearing part forms an attachment which can be attached to the upper edge of a container. The attachment to the upper edge of the container can take place by means of clamps known per se, such as with the aid of clamps which can be clamped together by a threaded bolt, and the like. On the other hand, the pressing device can also be introduced stationary on a stand or on a wall, and in order to enable easy adaptation to different container heights, it is advantageous if the bearing part is attached to a holder in a vertically adjustable manner. It is advantageous if the holder is formed by at least one perforated rail or plate, in the holes of which the bearing part can be selectively fixed for gradual height adjustment. On the other hand, it is also favorable if the holder is designed with clamps or as a clamping rail for the stepless height adjustment of the bearing part.

The invention is explained in more detail below on the basis of preferred exemplary embodiments illustrated in the drawing, to which, however, it is not intended to be limited. Show it:

FIG. 1 shows schematically a pressing device generally designated 1, at least currently regarded as particularly favorable, this pressing device 1 being attached to a collecting container 2 indicated by dashed lines, specifically at its upper edge 3, for example via clamping tabs not shown in detail attached to a frame structure (not shown) by means of clamping screws 4 (only one of which is shown schematically). In the case of such a detachable fastening of the pressing device 1 to the container 2, there can be a conventional container 2, which, for example, can have a pivoting cover 5 as usual.

The pressing device 1 has a bearing part 6, which is part of the frame construction (not shown) and is detachably connected to the container 2 via the clamping screws 4 - and in this respect is designed as a container attachment; However, this bearing part 6 could also be firmly connected to the container 2, but it can also be attached independently of the container 2, for example on a wall bracket, etc., as will be explained in more detail below.

On the bearing part 6, a pressing device generally designated 7 is pivotally mounted about a horizontal joint or pivot axis 8, and to actuate the pressing device 7, an angled hand lever 10 is articulated on the bearing part 7 above the articulation or pivot axis 8 at 9, which can accordingly be pivoted up and down about the pivot axis 9 parallel to the pivot axis 8 in accordance with the arrow 11. The hand lever 10 can in particular be designed like a bow, as is evident from FIGS. 14 to 16, which will be explained below, and as is known per se from EP 648 692 A1.

In the area of the bend 12 of the hand lever 10 is on this a connecting rod 13 hinged, see. also the schematically drawn hinge axis 14, and this connecting rod 13 is connected at its other, lower end via a hinge or swivel axis 15 to the pressing device 7, more precisely to an upper support part 16 thereof. This connecting rod 13 forms, together with the lever arm 17 of the hand lever 10 located between the two axes 9, 14, a toggle lever, this toggle lever 13, 17 being shown in the extended position in FIG. When the hand lever 10 is pivoted upward, the toggle lever 13, 17 in the joint 14 bends to the right as shown in FIG. 1.

An actual pressing part 18 can be extended on the supporting part 16 of the pressing device 7, i.e. downward displaceable, attached, see also Fig. 2 also Fig. 2, this extensibility or vertical downward movement of the pressing part 18 is indicated schematically by an arrow 19 in Fig. 2. As a result, in the operating position according to FIG. 2, this pressing part 18 protrudes substantially downward from the upper, horizontal articulation plane 8 ′, which runs through the articulation axis 8 and corresponds to the main plane of the support part 16.

Specifically, as can be seen in particular from FIG. 2, the pressing part 18 is connected to the supporting part 16 via a pair of articulated struts 20, 21, each articulated strut 20 or 21 consisting of two strut arms 22, 23, on the one hand, with one another are articulated, cf. additionally also FIGS. 3 and 4 and the swivel or articulated axis 24 shown there, and which, on the other hand, are connected to the supporting part 16 and to the pressing part 18 via joints 25 and 26, respectively. The joints 24 to 26, like the joints or pivot axes 8, 9, 14, 15, can be implemented in a conventional manner with the aid of pivot pins, etc.

As can be seen in particular from FIGS. 3 and 4, the strut arms 22, 23 are provided with welded-on eyelets or sleeves 27, 28, which in the extended position of the articulated struts (in FIGS. 3 and 4 is only one, according to FIG 2, the left hinge strut 20, and a mirror image of this would be the right hinge strut 21, with an identical but mirror-symmetrical structure, to be thought of) vertically aligned with each other, and through which a securing device provided with an angled handle part 29 would then be arranged - or locking pin 30 is inserted, cf. the representation in Fig. 4. Similarly, an eyelet or sleeve 31 is welded to the support member 16 in a position in alignment with the sleeve or eyelet 27 on the upper strut arm 22 in the pivoted-up state, so that in the retracted position of the articulated struts according to FIG. 3, the one provided for securing or fixing Pin or bolt 30 can be inserted through this eyelet or sleeve 31 in alignment with the eyelet or sleeve 27 so as to fix the actual pressing part 18 in the retracted position in contact with the supporting part 16.

From the mirror-image arrangement of the articulated struts 20, 21 and the design of the strut arms 22, 23 shown in FIG. 4, the lower strut arm 23 being provided with an angled upper end 32 to enable pivoting in and out and locking, as described above , it also results that the articulated struts 20, 21 can be folded or folded in opposite directions when they are brought from the extended position according to FIG. 2 or 4 into the folded position according to FIG. 1 or 3, see also that in FIG. 4 intermediate position shown with dash-dotted line.

To lock the strut arms 22, 23 of each articulated strut 20 or 21, of course, other locking means that are conventional per se can also be used. In particular, locking in the joint, in the region of the joint axis 24, would also be conceivable, wherein locking in different intermediate positions, corresponding to different heights of the actual pressing part 18, would also be possible.

It should also be mentioned that two such pairs of articulated struts, one on each of two opposite sides of the container 2, will generally have to be provided in order to obtain a stable connection between the supporting part 16 and the pressing part 18 of the pressing member 7. Furthermore, the support part 16 and the pressing part 18, as indicated in the present exemplary embodiment, can simply be formed by plates provided with side flanges, but it can also be a lattice or frame construction, cf. also the representation in FIGS. 14 to 16. These variation possibilities are of course also given in all of the embodiments explained below.

The embodiments shown in Figures 5 and 6 Pressing device 1 largely correspond to that according to FIGS. 1 to 4, so that the following description of these exemplary embodiments is only intended to be limited to the differences in these pressing devices, which in particular relate to the actual pressing part 18.

In particular, in the embodiments according to FIGS. 5 and 6, the separate pressing part 18 which is fastened to the supporting part 16 and in the operating position projects downward from it is simply pivotably connected to the supporting part 16 on one side. The pressing part 18 is articulated on the side of the supporting part 16 facing away from the bearing part 6 about a horizontal hinge axis 33, and at the other end of the pressing part 18 a hinge strut 20 'is provided which essentially corresponds to the hinge strut 20 according to FIG. 2 to 4 corresponds, and the folding up of the pressing part 18 and locking with the support part 16 as well as folding down and locking in the extended position with the aid of a pin or the like. 30 in the manner described in principle above with reference to FIGS. 3 and 4 enables.

Correspondingly, according to FIG. 6, the pressing part 18 is articulated on the supporting part 16 on the side thereof adjacent to the bearing part 6, with an articulated strut 21 ′ corresponding to the articulated strut 21 on the right in FIGS. 1 and 2 for locking in the pivoted-out part in FIG. 6 shown location is provided. Here, too, the pressed part 18 can be fixed in the pivoted-in position resting on the supporting part 16 (comparable to FIG. 1) in the manner explained with reference to FIG.

5 and 6, the similar actuation of the pressing device 1 via the toggle lever 13, 17 with the aid of the hand lever 10 can be seen, the controlled material flow to one or the other side of the ( not shown) container is made possible. In the embodiment according to Fig.l to 4, however, the material in the container 2 is simply compressed more or less vertically downwards. In all the exemplary embodiments described, however, the pressed part 18 penetrates sufficiently deep into the container 2 in the extended or unfolded operating position relative to the articulation plane 8 'of the pressing member 7 in order to remove the material collected therein, such as foils, cardboard pieces or the like originating from packaging . to condense. On the other hand, if material is subsequently refilled into the container 2, this additional material can be compacted by bringing the press part 18 into the retracted or folded-up position, and if necessary, if this is also provided, compacting with the press part 18 in intermediate positions is conceivable. In all of these cases, however, the container 2 can be filled up to the top with the material to be compressed, so that its receiving volume can be fully used. In addition, mutual independence of the pressing device 1 and container 2 can be achieved.

However, the displacement of the press part 18 with the actual press side (underside of the press part 18) with respect to the upper articulation plane 8 'defined by the pivot or articulation axis 8 downwards can also be achieved by providing a fixed press part 18 in the form of a press box 35 , as shown in Figures 7-10. 7 and 8, the actual pressing part 18 formed by the pressing box 35 is detachably connected, for example with the aid of schematically indicated screws or bolts 36, to the supporting part 16, which in turn is articulated at 8 on the bearing part 6 and in turn with its main plane defines the articulation plane 8 'against which the pressing part 18, ie Press box 35, with its underside protruding downwards or is offset. The press box 35 can, depending on the shape of the container (not shown in Fig. 7 to 11), be circular or square in cross section, and depending on the press box 35 can be cylindrical or prismatic (Fig. 7) or frustoconical or truncated pyramid (Fig. 8).

Similarly, in the exemplary embodiments according to FIGS. 9 and 10, a press box 35 is provided, but there is this press box 35 directly, with a flange-like extension 37, pivotably articulated on the bearing part 6 via the articulated axis 8, ie there is no separate support part here, and instead a one-piece unit supporting part - pressing part is formed. Here too, the press box 35 projects with its underside substantially downward relative to the articulation plane 8 '. Otherwise, the press box 35 is again either cylindrical or prismatic (Fig. 9) or frustoconical or truncated pyramid (Fig. 10). Furthermore, in the embodiments according to FIGS. 7 to 10, actuation by means of a toggle lever unit (toggle levers 17, 13) is provided, as explained above.

In the embodiment according to FIGS. 11 and 12, the pressing device 1 with the bearing part 6 is again placed in the area of the upper edge 3 of a container 2, and it also has a toggle lever device as described above, in particular with reference to FIGS 2, has been explained, so that a new description can be omitted in this regard. In the pressing device 1 according to FIGS. 11 and 12, a depressed pressing part 18 is likewise provided, see in particular FIG. 11, where this pressing part 18 is shown in the lowered operating position, and this pressing part 18 is, in comparison to the swiveled-up position of FIG Pressing device 1 (see FIG. 12) can be extended downwards. For this purpose, scissors 38 are provided, the scissor arms of which are slidably guided at the lower ends in elongated holes 39, 40 of the pressing part 18, and the upper ends of which are articulated on the supporting part 16 and on the other hand on the hand lever 10. This special articulated connection, with the scissors 38, is achieved - with a corresponding choice of the articulation points of the scissor arms on the support part 16 or hand lever 10 and appropriate dimensioning of the elongated holes 39, 40 - that when the hand lever 10 is folded up, the pressing part 18 is in contact is moved up on the hand lever 10, as shown in Fig.12. For this purpose, the press part 18 must be able to move between the laterally outer frame parts of the support part 16, which is to be designed frame-like or bow-shaped here, i.e. the support part 16 is preferably, for example, in the form of a U-shaped bracket in plan view - similar to that illustrated for the hand lever 10 in FIGS. 14 to 16. The elongated holes 39, 40 can also be provided in upstanding flanges of the otherwise plate-shaped (optionally also grid-shaped) pressed part 18.

In the embodiments according to FIGS. 1 to 4 or 11, 12, the bearing part 6 is designed as a container attachment, but it is equally conceivable to mount the bearing part 6 stationary on a frame or on a wall. This applies to all the pressing devices described so far, and an example of a fixed attachment of the pressing device 1, among which the respective container 2 is placed to compress the material contained therein, is shown in Fig. 13. Furthermore, a height-adjustable arrangement of the bearing part 6 on a stationary, wall-fixed holder 41 is also illustrated in order to enable the height of the pressing device 1 to be adapted to containers 2 of different heights.

13, a plate-shaped or rail-shaped holder 41 is fixedly attached to a wall 42, e.g. screwed, and along this holder 41, the bearing part 6 of the pressing device 1 is vertically adjustable, as is also illustrated by the lower position of the pressing device 1 shown in dashed lines, see also arrow 43 in FIG. 13. The pressing device 1 itself is designed essentially as in the previous exemplary embodiments; it again has a toggle lever unit and is here, for example, formed with a telescopically extendable pressing part 18 which can be fixed in various intermediate positions with the aid of pins 44 instead of with a pressing part 18 with pairs of articulated struts, as explained with reference to FIGS. 1 to 4, or with a downwardly pivotable pressing part 18, as illustrated in FIGS. 5 and 6 (an embodiment of the pressing part 18 according to one of FIGS. 7 to 10 or also FIGS. 11 and 12 would of course also be conceivable).

A telescopically extendable pressing part 18, as illustrated schematically in FIG. 13, can be obtained, for example, by the fact that in four corner points (in the case of a container 2 with a square cross section and correspondingly rectangular pressing part 18 or supporting part 16 in plan view) conventional telescopic tubes per se, which can have a round cross-section or quadrangular cross-section are attached, which can be moved into one another and can be fixed in different positions relative to one another with the aid of the pins 44 which are inserted through holes in the telescopic tubes. In this case, triple or quadruple telescopic tubes are also conceivable in order to reach a comparably large extension height (or small overall height in the pushed-together position).

14 to 17 show various possibilities for the height adjustment and locking of the pressing device 1 or more precisely of its bearing part 6 on the respective holder 41. clear. 14 to 16 show exemplary embodiments for a step-by-step height adjustment of the bearing part 6, whereas FIG. 17 shows, in detail, an option for a stepless height adjustment or, in connection therewith, fixation of the bearing part 6 in the holder 41 by clamping ¬ clear. 14 to 16 also show the pressing device 1 without the actual pressing part 18 for the sake of simplicity - only the respective supporting part 16 of the pressing device (7 in FIG. 1, 2) is illustrated; 17 shows only a part of the holder 41 and the bearing part 6, without the other parts of the pressing device 1.

14, the holder 41 is designed in the form of two angled perforated rails 45, these perforated rails 45 with one flange 46 on a wall (43 in FIG. 13) or on a frame plate or the like (not shown) in FIG suitable distance from each other, according to the width of the press device 1, are attached. The other, at right angles to the flanges 46 protruding flanges 47 are provided with holes 48 in a row one above the other, and with these holes 48 1 holes 49 in angled ends 50 of rails 51 of the bearing part depending on the height position of the pressing device 6 are aligned so that the bearing part 6 on the holder 41 can then be fixed at the desired height by means of screws, bolts, pins or the like (not shown). It should also be mentioned here that the illustration in FIG. 14 (as also in FIGS. 15 and 16) is only schematic, in particular a substantially greater overall height of the perforated rails 45 will normally be provided in order to adjust the height of the pressing device 1 via a to enable a correspondingly large area.

In the embodiment according to FIG. 15, the bearing part 6 has two bearing plates or rails 53 which are connected to one another by a horizontal rod 52 projecting on both sides and which, apart from the articulation points 8, 9, for the moving parts of the pressing device 1 (hand lever 10, supporting part 16), are each provided with a lower hole 54 through which a pin, a screw, a bolt or the like (not shown) is inserted, as well as through a hole 48 ′ aligned therewith in the angle rails 45 ″ of the stationary holder 41 , so the To fix bearing part 6 at the desired height on the holder 41. 15, the angle rails 45 'are provided with hook-shaped slots 55, in deviation from the embodiment according to FIG. 15, in order to be able to fix the rod 52 simply by hanging its outer ends in one of these slots 55. The rod 52 with its projecting ends is first pushed horizontally backwards and then moved downward in the angular slot 55, and in this position the pressing device 1 is finally fixed by a pin etc. which is inserted through the holes 48, 54.

The embodiment according to FIG. 16 is comparable in function to that according to FIG. 14. However, the bearing part 6 here has vertical tubes 56 (only one is shown in FIG. 16), to which bearing plates (comparable essentially to the bearing plates 53 in FIG. 15) for the articulation of the movable parts 10, 16 of the pressing device 1 are welded . The respective tube 56 is provided with an upper and a lower bore 57, and each tube 56 is displaceable along a vertical rod 58 provided with a row of holes, the fixing in the respective height position in turn by a pin, a screw or a bolt (not shown), which is inserted through the holes 57 and a corresponding hole in the rod 58. The rod 58 is attached to protruding horizontal legs 59 of a wall bracket 60 of the holder 41 (only one such wall bracket 60 is shown in FIG. 16 for the sake of simplicity).

According to FIG. 17, the wall-fixed holder 41 has generally C-shaped profile rails 61, on the front of which there is thus a vertical longitudinal slot, and which have an (undercut) groove 62, a threaded bolt 63 being vertically displaceable in the longitudinal slot . This threaded bolt 63 is screwed to a clamping piece 64 which is displaceable within the groove 62 of the clamping rail 61, and it is firmly connected to a hand lever 65 which is rotatably mounted on the bearing part 6 (or a part connected thereto). After setting the desired height of the bearing part 6 on the holder 41, by vertically moving the threaded bolt 63 in the longitudinal slot of the rail 61 or the clamping piece 64 in the groove 62 (of course after loosening the clamping piece 64), the threaded bolt 63 is through Rotation of the hand lever 65 is screwed deeper into the clamping piece 64, as a result of which the latter is clamped forward against the legs of the C-profile of the rail 61 which delimit the longitudinal slot; At the same time, the bearing part 6 is clamped against the outside of this leg of the rail 61, so that the bearing part 6 is clamped on the holder 41 in the desired height position. In this embodiment according to FIG. 18, a stepless height adjustment of the bearing part 6 and therefore of the pressing device 1 (not shown in FIG. 17) on the holder 41 is thus possible.

Finally, in FIGS. 18 and 19, pressing devices are illustrated essentially as described above with reference to FIGS. 1 to 4, only the actual pressing part 18 being modified compared to the embodiment according to FIGS. 1 to 4 insofar as it is required by additional components can be enlarged. Since otherwise the pressing devices 1 shown, for example with regard to the displaceable arrangement of the pressing part 18 on a supporting part 16 via articulated struts and with regard to the toggle lever actuation, correspond to that according to FIGS. 1 to 4, a repetition of the description can be omitted here.

According to FIG. 18, an enlargement part 66, which can be pushed out horizontally (via a rail guide, not shown, for example, a dovetail guide), is attached to the underside of the plate-shaped pressing part 18, for example, which thus increases the pressing surface to a maximum of slightly less than twice the size in comparison to that of the pressing part 18 alone.

According to FIG. 19, enlargement parts 67, 68, which are foldable in plan view, for example square (rectangular or square) press part 18, are hinged to two opposite sides or edges, for fixing them in the folded position as well as in the swung-up position in which they press part 18 enlarge to approximately twice the size of the pressing surface, conventional means such as those comparable to the eyelets or sleeves 27, 31 and the pin 30 according to FIG. 3 can be provided.

Of course, it would also be conceivable to provide such a fold-out enlargement part 67 or 68 only on one side. On the other hand, such enlargement parts 66, 67 and 68 can also be provided in the exemplary embodiments described above, for example in those in accordance with FIGS. 5 and 6, in accordance with FIGS. 11 and 12 or in accordance with FIG. 13. Furthermore, it also applies here that the bearing part 6 of the pressing device 1 can either be placed on a container 2 or attached stationary to a holder 41 fixed to the wall or frame, an adaptation to the cross-sectional size of the container 2 by the enlarging parts 66, 67, 68 can be achieved. The embodiment according to FIG. 19 is particularly advantageous in that a practically stepless enlargement of the pressing part 18 is possible, whereas in the embodiment according to FIG. 19 an enlargement only in two stages, by folding up an enlarging part 67 or 68 or else both enlargement parts 67 and 68, is possible.

Such enlargement parts 66 or 67 and 68 can in principle also be provided in a press part 18 designed as a press box 35 (see FIGS. 7 to 10). Otherwise, these press boxes 35 can also consist, for example, of full plastic bodies, but preferably of hollow sheet metal boxes.
