Abstract

The waste collector has a flap (20) closing off the waste depositing opening and which can be opened by a mechanism including especially a foot pedal (11), via an electronic release and/or via a sensor technique. The flap has the approximate shape of a quarter spherical shell segment can be opened wide enough to create a waste depositing opening of about the same size as the dimensions of a quarter spherical shell segment. The operating of the opening mechanism from the foot pedal is through a Bowden cable which acts upon the flap.

Description

The present invention relates to a waste collector having the features of the preamble of claim 1.

Waste collectors having a dome-shaped head portion and a hand-movable flap or hand-movable spherical shell segments are known ( US-A-5,492,239 ; US-A-5,292,023 ).

In the known waste collector from which the invention proceeds ( US-A-5,881,896 ) has a dome-shaped head part on a flap in the form of a spherical shell segment, which can be opened via an opening mechanism with a foot pedal at the bottom of the housing. To open the insertion opening, the flap is pivoted about an approximately horizontal pivot axis.

In the previously discussed, known waste collector, the foot pedal acts via a vertically extending linkage directly on the flap. For this purpose, the flap on a corresponding backdrop. The kinematics of this linkage arrangement is not optimal for the operation by means of the foot pedal.

The problem underlying the present invention is to constructively design the opening mechanism of the refuse collector with a flap which can be swiveled about an approximately horizontal pivot axis in a particularly simple and kinematically optimized manner.

The aforementioned problem is solved in a waste collector with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. Preferred embodiments and further developments are the subject of the dependent claims.

According to the invention, the opening mechanism has a cable pull element, in particular a Bowden cable, which acts on the flap closing the insertion opening. In this case, the cable pull element itself is connected to at least one driver, which in turn, optionally via further connecting elements, is in rotationally fixed connection with the pivotable flap. The driver is in the form of a wheel over which the cable pull element is guided, by means of which the opening movement of the flap is effected.

Although known from the prior art Seilzugelemente (Bowden cables) for opening a flap in waste collectors for US-A-5,163,574 ), but the structures proposed there can not be easily transferred to a pivotable about a horizontal, with respect to the flap pivot axis, spherical shell-shaped flap.

According to a preferred teaching, it is provided that the flap has approximately the shape of a quarter spherical shell segment and can be opened so far that an insertion opening of approximately the same size preferably results in the dimensions of a quarter spherical shell segment. Upon opening, the flap in the shape of the quarter cup shell segment is visually moved along a ball cup trajectory to the rear of the dome at the top of the garbage collector housing. One can thus divide the dome-shaped upper portion, which in principle has approximately the shape of a hemispherical shell, that on the front side facing the user, at the bottom of which the foot pedal is located, performs a quarter spherical shell segment as a movably pivotally mounted flap and in the rear area a fixed quarter spherical shell segment of the housing provides, behind which the opening quarter spherical shell segment is pushed. This leaves the rear half of the hemispherical shell-shaped dome stand during the opening process, while the front half so a quarter-ball shell with completely open flap (visor) forms a correspondingly large insertion opening.

The Bowden cable is an element by means of which a tensile force on an optionally greater distance can be transmitted with changes of direction. Instead of a Bowden cable or in addition to such one can also use another tension element, such as a cable with a plastic rope or the like.

According to the invention, it is possible that the visor-like flap slides during its pivoting movement over a fixed spherical shell segment of the dome of the housing, or that the visor-like flap is pushed under such a fixed part. The visually opening flap therefore moves about a horizontal pivot axis, which preferably extends radially in the middle across the lower region of the dome. The dome can be fixedly connected to the housing of the waste collector, for example. You can then dome and housing from above put over an inner bin of the waste bin and to empty the waste, the housing is lifted over the inner bucket. Alternatively, the dome with the visor-opening flap could alternatively be designed to be removable from the approximately cylindrical lower housing of the waste collector in order to empty the waste collector or for maintenance purposes.

The opening of the flap closing the insertion opening can be triggered electrically or electronically, in particular by means of a sensor technology. For this purpose, it is possible, for example, to use an infrared sensor or another motion detector, so that an approaching person sets in motion a mechanism which opens the flap. In all the variants mentioned includes the opening mechanism preferably at least one cable pull element. It is possible, for example, to work alone with a Bowden cable which, for example, extends from a lowerable foot pedal, preferably via corresponding deflections, to the flap and opens it via a pulling movement. But you can also combine, for example, a cable pull with a linkage. Since the waste collector is opened via a foot pedal, it can be operated by a first associated with this linkage, which in turn is then in connection with a cable pulling element which engages the flap. Depending on the design of the opening mechanism, the cable pull element and / or the linkage extend, for example, within the housing on the front side facing the foot pedal, at least in sections, or else on the rear side of the housing facing away from the foot pedal. In the upper region, the deflection then runs in each case correspondingly, that is to say either from the rear side to the front flap, wherein cable pull elements used there preferably extend in the circumferential direction at least in sections. Or in a variant of the invention, the cable pull elements initially extend from the front to the back, are deflected there and then extend back to the flap, so that you also here reaches a pulling movement that pulls the flap when opening inward.

In a variant of the invention, the opening mechanism comprises at least one with the foot pedal geared connected at least partially approximately vertically extending linkage. A preferred structural solution then provides, for example, that this linkage engages in the upper area under a plunger or a similar component when lowering the foot pedal. By lifting this plunger is then extending to an approximately in the peripheral region extending from the plunger in both circumferential directions extending tension element in the form of a Bowden cable, cable pull, plastic rope or the like acted, which is deflected so that the lifting of the plunger is converted into an attacking on the visor-like flap pulling movement, so that the tension element acts on the visor and pulls it around its axis to the rear , For example, in a pivoting movement with a pivot radius of 90 ° until the open position is reached. The leadership of the cable-like tension element is preferably via suitable guide elements and / or deflection elements, such as disc-like carrier with grooves over the circumference of the tension element is guided and which can be rotatably mounted about a horizontal pivot axis under the action of the tensile force, said pivot axis approximately with the Swivel axis of the visor-like flap can coincide. There are therefore for example two tension elements which extend from the plunger to both sides towards the drivers. If the plunger lifted by the linkage, this exerts a tensile force on the two tension elements, which in turn results in a rotational movement of the driver and a pivoting movement of the flap. Preferably, it is achieved by suitable spring elements that the flap moves back into its closed position after releasing the foot pedal. These can be used, for example, torsion springs, which are arranged in the region of the driver and are claimed upon rotation of the driver due to the force exerted on this via the tension element tensile force on torsion, so that they decrease in yield of the tensile force by their restoring force the driver and thus with turn back or pivot this connected flap.

According to a variant of the invention, the cable pull element initially extends from the foot pedal in the vertical direction and then separates into at least one adjoining section in two Seilzugstränge that extend at least partially within the housing of the waste bin in the circumferential direction. Preferably, guide elements are provided for the cable pull element, in particular for each section or strand of the cable pull element. In this variant of the invention, for example, be provided in the interior of the housing, an actuating bracket or a rocker on which the lower portion of the cable element is fixed. This actuating bow or the rocker is in turn preferably in communication with the foot pedal projecting outwardly through the housing. When lowering the foot pedal then a tensile force is then exerted directly, which pulls the cable pull element down, which then leads after appropriate deflection in the upper part of the waste collector to a pulling movement that pulls the flap when opening into the interior of the refuse collection housing. The said actuating bow can be pivotally mounted, for example, in the housing of the waste collector.

The cable pull element, which in the variant of the invention initially extends approximately from the height of the foot pedal inside the housing, extends at least in this lower region between the outer housing of the waste collector and an inner bucket that receives this outer housing. The inner bucket is then taken out of the outer bucket for emptying. Between the inner bucket and the outer bucket there is enough space to lay the cable pull element there.

The features mentioned in the dependent claims relate to preferred developments of the task solution according to the invention.

Further advantages of the invention will become apparent from the following detailed description.

Fig. 2 shows a longitudinal section through the dome-shaped head portion of the garbage collector, and you can see the flap 20 in the form of a quarter spherical shell segment, which can be opened in the arrow direction and then slides over a likewise approximately quarter spherical shell segment-shaped fixed housing part 21, wherein the flap 20 is a pivoting movement about a horizontal pivot axis 22 performs and out of the in Fig. 2 shown closed position at an angle of about 90 ° in the in Fig. 3 shown opening position is moved. On the approximately cylindrical housing 10 is the dome-shaped head part according to Fig. 2 fitted and removable from this. In addition to the fixed housing part 21 and the flap 20, the head part comprises a centering ring 23 which can engage in the cylindrical housing and a associated with this Einwurfring 25, which is inclined from the substantially vertically oriented centering ring 23 from the upper end of radially inwardly and extends downwards, like this Fig. 2 evident. By Einwurfring 25 ensures that dropped waste falls into the central 'opening of the cylindrical housing 10 of the waste bin. Attached to the Einwurfring 25, in particular two molded like bulges are upwardly extending housing body 27, the like Fig. 6 shows, on the circumference of the Einwurfrings 25 opposite each other. A vertical section through such a housing body 27 shows Fig. 7 , As can be seen there, takes the housing body 27 each have a driver 29 in the form of a wheel over which a cable pull element 30 is guided, by means of which the opening movement of the flap 20 is effected. How to get in Fig. 7 sees, the cable element 30 is located in a groove 29 a of the wheel-shaped driver. Detail views of the driver 29 are in the Fig. 8 to 10 shown. Detailed views of the cable element show the Fig. 11 to 13 ,

Below is on the Fig. 11 to 13 Referenced. The plan view of the cable element 30 according to Fig. 11 shows a plastic rope or a Bowden cable with two end attachment nipples 32, by means of which the cable pull element is fixed in each case at one end to one of the wheel-shaped carrier 29. In the middle of the cable pull element 30, a slider 33 is at this attached, the one in the side view also in Fig. 12 recognizes and from the in Fig. 13 an enlarged detail view is shown. This slider 33 has a bore 34 on the underside for receiving the plunger 24 (see Fig. 2 ). Below the lower end of the in Fig. 2 shown plunger 24 engages a through the housing 10 extending linkage (see Fig. 1 ), which causes raising of the plunger 24 when lowering a foot pedal 11. By this lifting of the plunger 24, the slider 33 is taken and also raised, which in turn exerts a tensile force on the attached to the slider 33 cable pull element 30. This tensile force is transmitted via the nipples 32 (see Fig. 11 ) on the wheel-shaped driver 29, which then around the horizontal pivot axis 22 (see Fig. 2 and Fig. 6 ) rotate.

As is apparent from the detailed view according to Fig. 7 shows, with the wheel-shaped drivers 29 each in the axis thereof, a bolt 28 rotatably connected, which in turn has at its outer end a head 28a, which engages over the flap 20 flange and which is in a fixed connection with the flap 20. As a result, upon rotation of the wheel-shaped driver 29, the bolt 28 and, in turn, the flap 20 is rotated, so that these are made of the in Fig. 2 illustrated closed position about the axis 22 in the open position according to Fig. 3 swings.

The Fig. 8 to 10 show the details of the wheel-shaped carrier 29. This one has, as can be seen from the FIGS. 9 and 10 sees, a hub 39 with a square receptacle 36 into which the square shank 35 of the bolt 28 can be inserted (see Fig. 7 ). The wheel-shaped carrier 29 further has a groove 29a for guiding the cable element 30. In each case one end attached to the cable pull element 30 nipple 32 is set in the part-cylindrical recess 38 of the driver 29, so that there the transmission of the tensile force of the cable pull element 30th takes place on the wheel-shaped carrier 29, resulting in a rotation of the driver. How to get out Fig. 10 recognizes the driver 29 also has on its inner side an annular recess 37 for receiving a leg spring 31 which in Fig. 7 is shown and which one also in Fig. 6 can recognize. Such a torsion spring 31 is located on both sides of each wheel-shaped carrier 29. Upon rotation of the driver 29, caused by the tensile force of the cable element 30, the leg spring 31 is subjected to torsion and thus stretched, so that upon release of the pulling movement, the leg springs 31 the Turn driver 29 back to its original position and thus fold back the visor 20 into the closed position.

With reference to Fig. 14 a further alternative variant of a waste collector according to the invention is explained below. Fig. 14 shows a vertical section through the waste collector, it can be seen that the outer housing 102 of the waste bin an inner bucket 105 receives, leaving between them an annular space, which is used for the accommodation of parts of the opening mechanism, in particular a cable element in the form of a Bowden cable 100 and the necessary guide elements can use. In this variant of the invention, the lowerable foot pedal 108 is connected to an actuating bracket 106, which separately for once again in Fig. 16 is shown. At this operating bracket 106, the lower end of the Bowden cable 100 is determined via a tie rod. The Bowden cable then runs vertically upwards therefrom and extends through a guide element, which comprises a double clip 112, which in turn can be fixed to the inside of the outer housing 102 via a receiving angle 114. From there, the Bowden cable 100 extends further vertically upwards and then branches into two separate strands 110, 111.

Further details regarding the design of the Bowden cable will be apparent from the schematically simplified illustration Fig. 18 , One recognizes there the tow hook 101, which exerts the pulling force on the lower end of the Bowden cable 100. Next, the double clip 112 is shown as a guide element. Thereafter, the Bowden cable branches into the two strands 110, 111, wherein for each strand also a clip-like guide element 113, 114 is provided in each case. The two strands 110, 111 then no longer run vertically but at least partially horizontally and extend in the circumferential direction, wherein the ends of these two strands are respectively fixed to drivers 29, as in Fig. 17 are shown and have already been described above with reference to the first embodiment. One recognizes in Fig. 17 also a portion of one of the strands 110 with the clip which serves as a guide element.

In Fig. 16 the partially annular actuating bracket 106 is shown in detail, from which one in Fig. 14 only recognizes a small section. As you can see, the actuating bracket 106 has a bore 116 for attachment of the in Fig. 18 recognizable towing hook 101 of the Bowden cable. This actuating bracket 106 is pivotable, wherein the pivoting movement by operation of the foot pedal 108 (see Fig. 14 ) is initiated and the pivot axis extends where there are two weld studs with shoulder 109, so that the actuating bracket 106 is pivotally mounted in the housing of the waste bin. The two adjustment units 117, 118 serve to adjust the Bowden cable.

The following is with reference to Fig. 19 an alternative embodiment of the invention explained. In this variant branches out differently than in the previously with reference to Fig. 18 described embodiment of the Bowden cable above not, but there is only one strand 110 available. This one strand 110 then also extends in the circumferential direction. It is here only a clipartiges guide element 113 required for the running in the circumferential direction strand 110 of the Bowden cable in the upper area. Instead of the double clip 112 in the variant according to Fig. 18 is in the embodiment according to Fig. 19 a simple clipart guide element 113 is present. This clip-like guide element 113 is then located, for example, on the inside of the outer housing of the waste collector and is fixed there, for example in a position as in the variant according to FIG Fig. 15 for the double clip 112 is shown. End is on the Bowden cable also in the variant according to Fig. 19 a tow hook 101 is provided, over which the lower end of the Bowden cable is fixed to an actuating bracket 106, so that it is entrained when lowering the foot pedal 108. Here is also on the Fig. 15 referenced, which refers to the embodiment described above, in which the tie rod is recognizable. The difference in the variant according to Fig. 19 is therefore that in the upper region only one strand 110 is present, which runs on one side in the circumferential direction. Such a strand 110 is sufficient in this variant to transmit the forces for opening the sight-like flap 20. Accordingly, one also follows the variant Fig. 19 with only one driver 29 on one side of the dome-shaped headboard. The deflection of the force on the driver 29 can in the variant after Fig. 19 in principle, be solved in a similar way as previously with reference to Fig. 17 has been described for the first embodiment.
