Definitions
- the invention relates to a waste container made of plastic material in the approximate shape of a standing cylinder with a hinged lid and two wheels which are mounted coaxially with one another in the recesses in the base region of the waste container and are connected to stub axles.
- the object of the invention is therefore to create a refuse container of the generic type in which the wheels and their storage can be manufactured and assembled in a very simple manner with the aid of a small number of individual parts.
- This object is achieved in a refuse container of the generic type in that bearing sleeves are provided within the indentations, which are integrally connected to the refuse container via a number of ribs, and in that the stub axles of the wheels together with the bearing sleeves have a locking mechanism for axial locking of the stub axles.
- the stub axles preferably have a plurality of, for example four, axially parallel slots distributed at their free ends, through which resilient tongues are formed at the end of the stub axle.
- These resilient tongues have outwardly directed hooks which are chamfered from the end of the stub and are formed in a harpoon-like manner and which positively engage behind the corresponding end of the two bearing sleeves.
- the bearing sleeves can have a circumferential bead on the corresponding side on the inner surface.
- the stub axles are preferably hollow or sleeve-shaped, and the inside diameter tapers in the area of the hooks via a beveled step.
- plugs integrally molded on are provided which have an outwardly projecting, circumferential bead on the side facing the stub ends and a flange-shaped projecting head piece on the opposite side. These plugs can be pressed into the open end of the stub axles, destroying the webs. In the end position, the bead engages behind the tapering of the inner diameter of the axle stubs at their corresponding end. After the plugs have been pressed in, the tongues can no longer be compressed and the hooks at the ends of the tongues can no longer be detached from the end of the stub axles.
- An intermediate sleeve made of slidable and wear-resistant material, in particular a suitable, harder plastic or even a metal, can be provided between the outer surface of the stub axles and the inner surface of the bearing sleeves.
- a waste bin made of polyethylene for example, polyethylene can be used for the intermediate sleeves, which has been subjected to a so-called self-reinforcement.
- the bearing sleeves are preferably connected in one piece to the base region of the refuse container within the indentations mentioned, which can also be referred to as wheel arches, via an open rib construction.
- the refuse container according to the invention can be produced entirely from plastic and in particular from one and the same plastic. eg polyethylene. It consists of only a few parts, including the wheels, which are relatively uncomplicated and can be easily connected to one another.
- plastic eg polyethylene. It consists of only a few parts, including the wheels, which are relatively uncomplicated and can be easily connected to one another.
- FIG. 1 shows a view in the upper half and a section through a wheel according to the invention with rim and axle stub, but without tire, in the lower half;
- Fig. 2 is a corresponding representation of a tire for the rim shown in Fig. 1;
- FIG. 3 is a partial side view of the lower region of a waste container with a bearing sleeve
- FIG. 4 is a partial view from the left in FIG. 3 of the lower corner region of a waste container
- Fig. 5 is a partial perspective view of the portion of the garbage container shown in Figs. 3 and 4;
- Fig. 6 shows a wheel in connection with a bearing sleeve at the lower corner area of a waste container.
- the wheel consists overall of a rim 10 and an axle stub 12.
- the rim 10 comprises a rim bed 14, a cylindrical hub 16 and an annular disk 18 connecting the two in the center plane of the wheel.
- the hub merges in a slightly recessed step 20 to the right in FIG. 1 into the likewise hollow cylindrical stub 12.
- the step 20 is reinforced by ribs 22 distributed over the circumference.
- the stub shaft 12 has a section 24, the cross-sectional shape of which deviates from that of the smooth hollow cylinder. First, the outside diameter of this section is slightly widened outwards from a position 26, which forms the beginning of section 24.
- the first section 28 has a cylindrical shape on the outside and the inside, while the second section 30 tapers both outside and inside to the center line 36 of the stub axle.
- the subsequent subsection 32 again runs cylindrical outside and inside, but with a reduced diameter compared to the stub axle 12.
- the last section 34 finally has the shape of an outwardly directed hook which is bevelled from the end of the stub axle.
- the entire section 24 is divided by four axially parallel slots 38 arranged in a cross into four segments or tongues 40, 42 distributed over the circumference.
- the tongues can be compressed resiliently.
- a cylindrical stopper which is denoted by 44 and which is connected to the stub shaft 12 by means of thin webs, not shown. In this way, the wheel, the stub axle and the plug 44 can be injection molded together. The shape and function of the stopper will be discussed later in connection with FIG. 6.
- FIG. 2 shows a tire for a rim 10 according to FIG. 1, which is made of an elastomeric material and can be sprayed directly onto the rim.
- the tire will be explained in more detail later.
- a bearing sleeve for the stub axle 12 and its arrangement in the lower edge region of a refuse container will then be described with reference to FIGS. 3 to 5.
- 3 to 5 an only partially indicated refuse container is designated by 46.
- the garbage container has indentations 48 in its lower edge region at two adjacent corners, which can also be referred to as wheel arches.
- Within these two inputs Bays are two bearing sleeves 50, 52 (FIGS. 3, 5 and 6) connected to the outer surface of the waste container by a number of connecting and stiffening ribs 54, 56, 58, 60, 62 (FIGS. 3 and 5).
- the ribs run in different directions from the circumference of the bearing sleeves and thus allow the wheels to be supported against forces from different directions.
- the ribs 54 and 58 run on the two opposite sides of the bearing sleeves 52 in the vertical direction and are pulled over the entire width of the waste container, so that they also connect the two bearing sleeves to one another for additional stiffening.
- the remaining, inclined ribs have only the width of the relatively small length of the bearing sleeves.
- FIG. 6 a wheel with the rim 10 and the axle stub 12 is shown, which have already been explained with reference to FIG. 1.
- a tire 64 made of an elastomeric material which as such is shown in FIG. 2.
- the bearing sleeve 50 is provided at its inner end facing the other bearing sleeve, which is not shown in FIG. 6, with a bead 66 which runs around the inner surface and is chamfered into the sleeve.
- the cross-sectional shape of this bead 66 adapts precisely to the contour of the partial sections 30 and 32 explained with reference to FIG. 1 on the outside of the stub axle 12. Therefore, when the stub shaft 12 is inserted into the bearing sleeve 50 from the left in FIG. 6, the hook-shaped sections 34 at the end of the stub shaft 12 run onto the slope of the bead 66. As a result, the hook-shaped segments 40, 42 of the section 24 are pressed inwards until they have reached the position shown in FIG. 6, in which the hooks of the outer sections 34 engage positively behind the end face of the bearing sleeve 50 or of the bead 66 . In this position, the stub axle 12 is locked in the bearing sleeve 50 without further measures
- the already briefly mentioned stopper 44 according to FIG. 1 serves to additionally secure the axle stub 12.
- This stopper is connected to the axle stub 12 only via the short webs, which are not designated.
- the plug has at its end facing the stub 12 on the outer circumference a circumferential bead 68 which is bevelled on both sides and at the other, outer end a flange 70 projecting head plate.
- the segments 40, 42 first run onto the beveled bead 68 of the stopper 44 until this bead has the shape of a truncated cone in the direction of the stopper, designated 30 converging section of the stub axle 12 has reached.
- the bulge 68 is fixed behind this inclined surface of the section 30.
- the top plate 70 lies against the end of the stub shaft 12 from the outside. Pulling out or even falling out of the stopper is no longer possible in this position.
- the segments 40, 42 of the stub axle can no longer be pressed together, so that the wheel with the stub axle is permanently secured in the bearing sleeve 50.
- This intermediate sleeve 72 consists of a harder material than the other parts of the refuse container and thus serves on the one hand to reinforce and stiffen the axle stub 12, but also has favorable sliding properties with respect to the adjoining plastic materials of the axle stump and / or the bearing sleeve.
- Suitable material is a suitable metal, but also a plastic with higher strength compared to the plastic of the container, for example a plastic which is increased in its module by self-reinforcement.
- the intermediate sleeve is supported in the axial direction on the one hand via an unspecified, flanged edge on the hub 16 and on the other hand on the step formed in position 26 on the outside of the stub axle.
