Description

I. Application work

The invention relates to a refuse container with a body according to the preamble of claim 1.

II. Technical background

Such garbage containers hold about 1,000 liters and can therefore reach a weight of more than one ton in the filled state.

In the prior art, generic garbage containers are known, which have a body, on whose sides facing away from each side walls a receiving pin in the form of one of the receiving pin laterally protecting pin unit is mounted, which survive the outward and buttoned down Engages under the edge of the body, wherein the pin unit has an upper portion and a lower portion of a central socket which represents the receiving pin has (for example in DE 3001703 ).

The emptying takes place in that on the outside of two opposite side walls of the container outwardly receiving pins are arranged, which consists of two fork-shaped receptacles of the Removing vehicles taken and thus the entire container is lifted, tilted and emptied. Accordingly, the receiving pin must be made very stable and connected to the container. For reasons of emptying process, the receiving pins have to be approximately in the middle of the frontal walls, ie an area which is usually thin-walled and formed without major stiffeners.

It is therefore already known, the receiving pin not in one piece in the manufacture of the container - which usually happens by means of plastic injection molding - form, but instead a separate, shell-shaped injection molded part, the so-called pin unit, in addition, a tubular metal reinforcement housed as a receiving pin to attach to the outside of the body, in particular to screw.

It is also already known to insert this pin unit under the double cranked, outwardly projecting edge and thereby to create a positive connection of these two parts in the upper region of the pin unit.

However, it has been shown that z. B. due to incomplete filling of the container, but with particular materials very high density, it lacks the inner support of the pin-receiving by the case material and can lead to deformation of the walls.

III. Presentation of the invention a) Technical task

It is therefore the object of the present invention, the container and in particular the pin unit so educate that a very stable connection of the receiving pin to the container with the lowest possible weight and installation cost and size of the pin unit is achieved, and a forwarding the forces in the most stable zones of the container.

b) Solution of the task

This object is solved by the characterizing features of claims 1 and 19. Advantageous embodiments will be apparent from the dependent claims.

By the widest possible training of the upper, the edge under cross-section of the pin unit and the central socket,
which represents the receiving pin, leading away radial ribbing forces can be transmitted from the central sleeve to the outer ends of the upper portion obliquely upwards and thus to the very stable trained container lids out. This applies even more to all forces that are steeper upward.

Therefore, the pin unit in the upper, the edge under cross-section, in the plan view of the pin unit a much larger width than in the lower area at the height of the receiving pin.

Therefore, the transition between the wide, upper portion and the narrower lower portion is designed either V-shaped or T-shaped with a strongly rounded transition, wherein preferably the radially obliquely upwardly extending ribs are directed tangentially to the transition radius of the outer wall.

In addition, preferably vertical and / or horizontal ribs are arranged in the cup-shaped part, which is mounted with the open side towards the body and which extend between the bushing and the outer edge of the middle part and with both the upper and the lower edge and / or other ribs have connection.

For the purpose of screwing the impact points of the radial ribs are formed thickened with the outer edge of the pin unit, especially set back slightly from the edge into the ribs, and are used for screwing self-tapping screws or have for this purpose already preformed, the open side of the pin Unit open, blind holes on.

Thus, for example, by the horizontal and vertical ribs create a grid, with a socket is centrally located in one of the resulting compartments, and in particular its corners is radially ribbed, in particular, a horizontal and vertical rib reaches this socket.

The inserted in the central sleeve made of plastic metal reinforcement in the form of a piece of pipe or metal tube is inserted into the socket just fit and is based in the assembled state on its outer end on the inner surface of the continuous outer wall of the pin unit from and on its inner end face the wall of the corpus.

In addition, viewed in the side view, ie viewing direction transversely to the receiving pin, the transition from the projecting receiving pin into the outer wall surface of the pin unit can be designed to transition obliquely to improve the introduction of force by means of the ribs.

To further stiffen the upper area, the outer wall initially points a crank, which can be applied to the lower free end of the downwardly facing edge of the body and can transfer form-fitting forces on this support. In addition, the upper portion of the pin unit by inserting a running in the horizontal direction, so the width of the upper portion, metal part done, either a pipe, an open profile or a flat material, then with lying cross-section.

Such a reinforcement may be inserted in a corresponding receiving space from the open back of the cup-shaped pin unit, but then there is a need to interrupt in this area the vertically or obliquely upwardly extending ribs, which serve the reinforcement, which stabilizing drastically worsened by the ribs.

Alternatively, such reinforcement may be inserted longitudinally of the upper portion through an end opening in the upper portion, prior to assembly of the pin unit to the container. In this case, the insertion opening can be placed so high that it disappears after assembly under the bent edge and thus is no longer visible and accessible.

Another possibility is to interpose a lying flat material, an angle profile or a downwardly open U-profile between the interior of the downwardly open edge and there inserted from below upper portion of the pin unit, which are dimensioned smaller according to the wall thickness of this material got to.

The width of the upper region is chosen as large as possible, and in practice best extends to corresponding cross struts in the interior of the downwardly open edge, for example in the form of the left and right outside of the End wall existing handles or receiving openings for plug-in handles in the edge are available.

In a V-shaped pin unit, the opening angle of the V in the area above the receiving pin is preferably selected so that in this area the outer edge on the line between the center of the receiving pin and the free outer end of the upper area, So the upper corners of the pin unit, lies. The outer edge is to be considered in all designs without kink and with the largest possible rounding viewed in the plan to favor the power line in the longitudinal direction of the edge and hinder its buckling.

If - especially without reinforcement of the upper region by a horizontal metal part - a further stabilization especially of the double cranked edge is to be achieved, so in the width range of the pin unit one or more stiffening webs must be arranged in the edge.

At these points, the upper, pushed under the edge area of the pin unit can not reach up to the upper groove bottom of the edge, but must here corresponding, open at the top, gaps.

For this purpose, the upper portion of the pin unit on the one hand and the edge of the body on the other hand in the longitudinal direction alternately vertically extending transverse webs, or these stiffening webs may even be at the same longitudinal positions, but great z. B. rectangular cross section of the edge depending only half, in the form of a triangle from.

As Fig. 2a - c show the side wall 25 of the body 1 ends at the top in a double outwardly bent bottom edge 7, thus comprising a horizontally outwardly facing connecting leg and at its free end facing down, down below freely terminating and extending at a distance from the side wall vertical leg ,

In the downwardly open interior of the edge of the cup-shaped plastic part, which represents the pin unit 29 substantially, with its upper portion 29 a as far as possible pushed. It can be seen that due to a crank 41 of the outer wall 40 of the pin unit 29, the pin unit 29 under the Edge 7 protrudes outwardly and in particular flush with its outer edge, and in turn, in turn, the receiving pin 28 itself further protrudes outward.

In the supervision according to Fig. 1 It can be seen that this edge 7 passes substantially over the entire width of the side wall 25, but the interior through mounting holes 13, which are arranged in pairs in the left and right end and serve the insertion of stoppers 6, interrupted.

The pin unit 29 extends therebetween above the entire remaining width and is located with the crank 41 of its outer wall 40 at the lower end of the free leg of the edge 7 and / or with its upper edge on the downwardly facing groove bottom of the edge. 7

Screws 43 are screwed from the inside of the side wall 25 through this and end in blind holes 34 of the pin unit 29, which is designed as the body toward the open, cup-shaped, ribbed, outside of a closed outer wall 40, plastic injection molded part.

In the middle of the downwardly projecting leg of the T-shape of the pin unit 29, the central sleeve 30 is integrally formed with the pin unit 29, in which from the open side, the reinforcing metal tube 31 is inserted accurately.

Of the bush 30 rich-like the rear view of the Fig. 3 radial ribs 32a, b, c .. outward, which meet the edge 33 which is formed integrally and opposite the outer wall 40 cranked.

Close to the connection points between the edge 33 and the radial ribs 32a, b, c..., Which are thickened, the blind holes 34 are formed.

In addition, as in the left half of the Fig. 3 drawn-vertical ribs 35 from the upper edge 33 to the lower edge 33 may be continuously present, for example, in the region between the sleeve 30 and the vertical outer edge.

The ribs 32a, c running obliquely upwards from the bush 30 are the most heavily loaded ribs and extend tangentially into the edge at the inner radius at the transition between the vertical middle leg and the transverse upper portion of the pin unit 29, and from there to the upper inner corners of the pin unit 29 and the local edge 33rd

For further stabilization, a profile 37 or a flat material 36 can be introduced in the longitudinal direction, that is to say the width, of the upper region 29a of the pin unit 29, which preferably extends as far as the inner surfaces of the front edges of the upper region.

Fig. 2a shows an angle section 37 ', which is arranged on the outer surface of the side wall and under the transverse leg of the side edge and is positively held only by the bottom pressed against the upper edge 33 of the pin units 29.

• Dabei zeigt Fig. 3 im rechten Teil einen zur Rückseite hin offenen Aufnahmeraum 38 für ein Flachmaterial 36, welches mit im montierten zustand flachliegendem Querschnitt eingelegt wird, da die Biegekräfte dann in Richtung seiner größten Querschnittserstreckung auftreten.

Alternatively or additionally, an additional stiffening element may be arranged in the upper region 29a:

• It shows Fig. 3 in the right part of an open towards the rear receiving space 38 for a flat material 36, which is inserted in the assembled state flat-lying cross section, since the bending forces then occur in the direction of its greatest cross-sectional extent.

The receiving space 38 is adapted as accurately as possible to the dimensions of the reinforcing member. The disadvantage here is the necessary interruption of the vertical or obliquely upwardly extending ribs in this area.

Remedy here in the Fig. 2c drawn flat material 36 which according to Figure 2c must be inserted in its longitudinal direction in receiving spaces 38 in the ribs, which are thus on all sides of the ribs 32 l - q, 35 enclosed and thus affect their stability only slightly.

For insertion, the edge 33 of the pin unit 29 has an end opening, which is preferably so high that it is higher in the mounted state than the lower edge of the edge 7 and thus neither accessible nor visible.

Accordingly, the pin unit can be mounted by first the metal tube 31 is inserted from the open back into the socket 30, before or after the profile 37 or sheet 36 is inserted from the frontal opening in the pin unit 29 in its longitudinal extent and thereafter the pin unit 29 is inserted with its upper portion under the edge 7 and screwed in this position by means of the screws 43 from the inside of the side wall 25 from.

If, in addition or instead, another angle profile 37 'between the pin unit 29 and the edge 7 is to be inserted, as in Fig. 2a , This is always possible before or during insertion of the pin unit 29 under the edge.

• Dabei sind an ein oder mehreren Stellen in Längserstreckung des Randes 7 Versteifungssiege
  42 zwischen dem äußeren freien um den Schenkel des Randes 7 an der Seitenwand angeordnet. Lediglich im Bereich zwischen diesen Versteifungsstegen 42 reicht der obere Bereich 29a bis ganz nach oben in den Innenraum der Nut des Randes 7 hinein, was dessen Stabilität jedoch beeinträchtigt.

Fig. 1 shows a stiffening option in addition or without inserted in the upper part metal part:

• Here are at one or more points in the longitudinal extension of the edge 7 stiffening victories
  42 disposed between the outer free around the leg of the edge 7 on the side wall. Only in the area between these stiffening webs 42 does the upper area 29a reach all the way into the interior of the groove of the edge 7, which impairs its stability, however.

• Der zur Seitenwand 25 hinweisende, diagonal geteilte, dreieckige obere Bereich steht für entsprechende dreieckige Versteifungsstege 42 des Randes 7 zur Verfügung, während an gleicher Position oder auch demgegenüber versetzt der untere dreieckige Bereich 29b für Versteifungsstege 42' der Zapfen-Einheiten 29 zur Verfügung steht, dessen oberer Rand sich jedoch im Bereich zwischen den Stegen 42 bis zur Seitenwand 25 hin erstrecken kann.

Alternatively shows Fig. 2b a solution in which the approximately rectangular free cross section of the edge 7 for stiffening webs 42 of the edge on the one hand and 42 'of the pin unit 29 on the other hand is divided:

• The diagonally divided, triangular upper area pointing towards the side wall 25 is available for corresponding triangular stiffening webs 42 of the edge 7, while the lower triangular area 29b for stiffening webs 42 'of the pin units 29 is available at the same position or else in opposite directions, however, its upper edge may extend in the area between the webs 42 to the side wall 25.

There are then also stiffening webs 42 'with completely filling the interior of the edge, so z. B. rectangular, cross section possible. Furthermore, the side view of Fig. 2d in that the outer wall 40 can not run out from the neck of the receiving pin 28 at right angles, but at an obtuse angle, so that a cone tapering towards the receiving pin 28 is formed in order to improve the force transmission, in particular below ends at the edge 33 and at the top of the upper portion 29 a, which can be pushed under the edge 7 of the body 1.

Furthermore, in Fig. 2a to recognize in one of the screws 43, that the thickened screw receptacle of the pin unit 29 continues beyond the open back of the pin unit cone-shaped, for centering in a local bore of the side wall 25 of the body first

Fig. 4 shows - in the same direction as Fig. 3 So, from the open back, another form of ribbing.

In the interior of the pin unit are horizontally extending ribs 32l - q and vertically extending ribs 35, 32b, arranged, with a horizontal and a vertical rib each point to the center of the socket 30, which acts as their crossing point. In addition, diagonal ribs 32a ', 32c- ... extend diagonally outwardly from this bushing 30 to the adjacent crossing points of the horizontal and vertical ribs to which they pass, but not beyond.

In the lower portion 29b thickened screw receptacles - again near the peripheral edge 33 - are arranged on the one hand in the horizontal rib, which aim at the center of the sleeve 30 and on the other hand in the vertical ribs, the side of the sleeve, approximately in the middle between the socket and the lateral edge 33, run down, of which only one is present.

In the upper region, a horizontal rib 32q extends at the level of the lower edge of the upper region, and merges tangentially into the edge 33 at the point at which it reaches the end face of the pin unit 29 approximately horizontally. 5 A further horizontal rib 32p is arranged at a distance above it, but is even lower than the recess in the outer wall 40, which is supported on the freely downwardly pointing leg of the edge.

Above this horizontal rib 32p, only the two vertical ribs 35 extending laterally of the bushing 30, or no vertical rib, extend upward, while the central radial vertical rib 32b merges therewith and terminates in it.

Thickened screw receptacles are preferably formed in this highest horizontal rib 32p at the crossing points with the vertical ribs 35, 32b, as well as near the front end of this horizontal rib 32p.

In addition, in the course of the horizontal rib approximately in the middle between the vertical plane of symmetry of the pin unit 29 and the outer front end of the upper portion 29a, a further screw receptacle may be formed as a thickening of the rib 32p, as in the left half of FIG Fig. 4 shown.

One of the screw receptacles, preferably one of the lowest-lying screw receptacle, is projecting over the rear side and in particular conically projecting as a centering aid, as described with reference to FIGS Fig. 2a explained.
