Abstract

The refuse container has a rectangular cross-section. The body part is provided with a suspension strip (21), which acts as a stop during tipping, in the region of its upper edge, which is reinforced by struts (23, 24, 29) connected to the body part (20). Attached to the outside of the suspension strip (21) is a reinforcing strip (22) projecting approximately perpendicularly from the latter and integrally connected to the suspension strip. Plate-shaped struts (34) are provided between the reinforcing strip (22) and the suspension strip (21) and extend, with their top edges, beyond the top edge of the projecting rim of the suspension strip. The suspension strip may be exposed to relatively high stresses, it has a longer service life, and its stop function is improved. <IMAGE>

Description

(54) REFUSE CONTAINERS (71) We, SCHNEIDER STÄDT- EREINIGUNG GMBH & CO. K.G. a Com- pany organised and existing under the laws of the Federal Republic of Germany, of 6346 Oberscheld, Falkenstein I BRED, Germany, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to containers for refuse.

One kind of refuse container is of rectangular cross-section comprising a cover and a body, which latter is provided at one side in the vicinity of its upper edge with a depending flange stiffened by struts connected to the body.

Increasingly refuse containers are mass produced in plastics material and refuse containers of the above kind - which require depending flanges - are particularly liable to damage.

The reason for this is not only that the flanges or the like are particularly strained during the heavy impacts arising from the emptying of the refuse, but also because fluctuating temperatures, to which most refuse containers are subjected in the open, lead to deformation or dislocation of the flange, so that in some cases the container itself becomes no longer usable.

German Gebrauchsmuster 76 11 603 discloses a refuse container comprising a cover and a body in which one or more profiled metal parts are used between the flange and the body to reinforce the former. This metallic reinforcement however involves difficulties during the manufacture of the plastcs container and considerably increases the cost; moreover the flange is not adequately protected against deformation or bowing; apart from this the aforesaid metallic reinforcement does not help the abutment surface of this flange.

It is an object of the invention to provide an improved container for refuse.

The present invention provides a container for refuse, comprising a body of substantially rectangular cross-section having a cover therefor, a depending flange which extends along one side wall of the body in the region of an upper edge of said wail and is stiffened by substantially vertically arranged struts connected to the body, and a rib which extends substantially parallel with the body between the body and the depending flange; and wherein a reinforcing member is provided for said flange, said member extending along and projecting laterally from said flange and being adapted and arranged to serve as an abutment for said container during emptying thereof.

The reinforcing member is preferably integral with the flange.

The reinforcing member not only serves directly for reinforcement of the flange, thus reducing the possibility of the latter becoming warped or deformed, but at the same time it can serve as an abutment for the refuse container in the end phase of the tipping and pouring of the contents and an additional abutment for the refuse container on the front plate of a chute.

Advantageously a portion of the reinforcing member extends substantially parallel to and laterally offset from the remainder of the reinforcing member.

Conveniently the reinforcing member has an impact rib thereon, said impact rib extending longitudinally of said member. The impact rib is advantageously located at the free edge of the reinforcing bar. Preferably said offset portion of the reinforcing member is connected to said remainder by two mirror-image cranked portions thereof located equidistant from the respective ends of the flange.

Preferably, at least said offset portion of the reinforcing member directly adjoins the free edge of the flange.

Conveniently, the impact bar, the reinforcing member and the flange together define an assembly of U-shape in cross-section, opening towards a base of the container.

Preferably the flange extends at an acute angle, the reinforcing member extends at right angles and the impact bar extends substantially parallel to said wall of the body.

The reinforcing member may advantageously be provided with stiffening wall members which extend normally thereto.

The stiffening wall members may be provided above the reinforcing member.

A free edge of each stiffening wall member preferably extends parallel to the cover and projects beyond the upper edge of the flange.

This embodiment has the additional advantage that the outstanding edges can be utilised for the action of pouring the refuse container.

The present invention is further described hereinafter, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a partial cross-section through a refuse container, Figure 2 is a section on the line 2-2 of Figure 1, Figure 3 is a side view of a part of the body of a refuse container, Figure 4 is a side view similar to that of Figure 1 of part of a modified body section similar to that of Figure 3, Figure 5 is a detail of the arrangement illustrated in Figure 3, this being partly in section, Figure 6 is a detail similar to that of Figure 5 but showing a modified arrangement, Figure 7 is a section taken on the line 7-7 of Figure 3, Figure 8 is a detail similar to that of Figure 5 but showing a section of another modifi cation, Figure 9 is a detail similar to that of Figure 5 showing a section of yet another embodiment, and Figure 10 is a cross sectional view taken on the line 10-10 of Figure 3 but shown on a smaller scale.

A refuse container of plastics material con sisting of a body 1 and a cover 2 has a hori zontally outstanding rim 3 which is disposed around the complete body which can be of square cross section. Adjoining the rim 3 is a depending flange 4 which extends substantially parallel to the side wall of the body and like wise can be provided at all four sides of the container. Other than the sides illustrated in Figure 2, the rim at the opposite side (not shown) of the refuse container has no suspen sion function.

The flange 4 is reinforced by a plate-form vertical struts 5. Such struts can be provided even at the corners 6 of the container.

A stiffening rib 7 parallel to the wall of the body is provided beneath the rim 3.

Where the refuse container is provided with a device for suspension in a so-called comb bar, the spacing between the individual struts 5 is approximately uniform, as illustrated in Figure 2. The intervening space is however divided up by smaller struts 8. The lower edges 9 of these struts are flush with the lower edge 10 of the rib 7. It has been found that the flange 4 might be deformed between two struts 5 and 8. As a result of such deformations the area enclosed by the body part, the struts and the flange 4 can be reduced, and this can continue until the teeth of the comb bar will no longer find sufficient room for penetration with the result that the refuse container will no longer be capable of being hung in the garbage truck and will therefore become useless.

Provided at the outer edge of the flange 4 is a continuous reinforcing member in the form of a bar 12 which has been illustrated with dotted lines in Figure 2. This reinforcing bar 12 prevents any enlargement or other deformation of the flange 4 at this side; at the other side the rim provided by the reinforcing bar 12 can be used as a fastening abutment against the chute device of a garbage truck during the end phase of the tipping. The front plate has been indicated by a dotted line 13.

In the known refuse containers of this type the spacing between the front side 14 of the cover and the flange 4 has served as an appropriate abutment surface, but this has not been satisfactory because in many instances this surface is too narrow. In addition this led to unsatisfactory and undesirable loading of the projecting rim 3 and the latter could not be used as a locking abutment during the end of the hoisting phase.

The body part 20 of a refuse container according to Figure 3 is again provided with a surrounding depending flange 21. The side of the body illustrated is opposite the hanging part of the container (not shown), and is the so-called abutment side for application at the front plate of a tipping device. The reinforcing bars 22 are at right angles to the flange 21.

The bars 22 are integrally connected to the container and these can be of plastics material.

The reinforcing bars 22 prevent a bellying out of the flange at right angles to the plane of the drawing and at the same time serve - as indicated above - as an abutment during pouring.

The peripheral flange 21 is however not used at the three sides of the container which have not been shown but which are provided with reinforcements 23 on the body 20, and thereby stiffened.

At the side opposite the hanging side and at this side only, the refuse container is provided with a notching between the flange and the body, as will be described below in reference to Figure 10. As can be seen from Figure 7 the reinforcing bar 22 stands out from the suspension side of the refuse container. Struts 24, for example of triangular form, are also provided at the flange.

In the embodiment illustrated in Figure 3 and Figure 7 the reinforcing bar 22 is flanged at the central part, that is to say at a location the same distance from its two free ends, so that on the one hand the flange 21 is of less height at the area 25 and, on the other hand, the reinforcing bar 22 is bent over the offsettings 26 and 27 towards the upper rim 28 of the body 20.

In addition to the two triangular struts 24 a corresponding central strut 29 may be provided having a similar form to the wall-like struts 23 and 24.

As can be seen from Figure 7 and Figure 10 notched reinforcements are again provided between the body 20 and the flange 21, below the projecting rim 30. The reinforcements comprise a rib 31 parallel to the wall of the body of the container and wall-like struts 32, 33 extending at right angles thereto.

Between the reinforcing bar 22 on the one hand and the flange 21 on the other use is made of two rectangular plate-like struts 34 extending parallel to the plane of the drawing.

These plate-form struts, as can be seen from Figure 3 and Figure 7 have their upper edge 35 extending above the upper edge 36 of the projecting rim 30.

The plate-form struts provided in the embodiment of Figure 3 and Figure 7 not only fulfil a stiffening function in relation to the flange 21 and the reinforcing bar 22 extending at right angles from the free end thereof, but can be used also by the operator for guidance in applying and suspending the refuse container in the chute device.

The embodiment illustrated in Figure 6 differs from the embodiment described immediately above solely in the fact that the upper edges of the plate struts 40 are flush with the upper edge 36 of the projecting rim 30; however in this case also these struts 40 can be used for guidance.

In the embodiment illustrated in Figure 5 the plate-form struts between the flange 21 and the reinforcing bar 22 are completely dispensed with.

In the embodiment illustrated in Figure 9 the flange has a form, at the hanging side only, which can differ from those on the three other sides. Whilst on the three other sides the flange 21 is generally parallel to the body 20, in this embodiment the flange 50 is at an angle of approximately 20 to the vertical. Adjoining the flange 50 is a reinforcing bar 51 which is approximately at right angles to the body wall; outstanding from the latter is in turn an impact bar 52 which extends parallel to the body 20.

Even in this embodiment notched or gridlike reinforcements are provided, additionally to the wall-like struts 24, between the flange 50 on the one hand and the reinforcing bar 51 on the other, and between the latter and the impact plate 52. The plate-form reinforcements 53 which for example are provided on the flange 50 have a free edge 54 extending parallel to the flange 50. the reinforcing bar 51 is stiffened relatively to the flange 50 by these, for example four or six, plate-form reinforcements 53. Correspondingly triangular reinforcements 55 can be provided beneath the impact bar 52.

The embodiment illustrated in Figure 4 differs from that of Figure 3 only in the fact that the flange 21 is extended beyond the reinforcing bar 22. The reinforcing bar 22 is straight throughout in this embodiment.

The recess 60 of the flange 21 in the central region of the body 20 serves, in exactly the same way as the cranked parts 26, 27 in the embodiment of Figure 3, in reducing the height of the flange 21 at least partially and this, in the case of a product made of plastics material for example by injection moulding, is of decisive advantage because it increases the discharge possibilities and thus a more accurate aiming of the contents.

Finally in the embodiment illustrated in Figure 8, which has a projecting rim 30 and a flange 21, the reinforcing bar 22 is constructed to provide an impact bar 52 parallel to the body of the container adjoining this.

In principle in the embodiment of Figure 8 the flange 21 is extended beyond the reinforcing bar 22 so that there is a U-shaped cross sectional profile defined between the impact bar 52, the reinforcing bar 22 and the lower part 61 of the flange 21. The impact bar 52 is resilient, so that the abutment against the front plate of the chute device will be of a yielding nature thus avoiding the danger that when the container is tipped the latter can be thrown out from the front plate or the tipping device.

The plate-form reinforcements 53 which for example are provided on the flange 50 have a free edge 54 extending parallel to the flange 50. the reinforcing bar 51 is stiffened relatively to the flange 50 by these, for example four or six, plate-form reinforcements 53. Correspondingly triangular reinforcements 55 can be provided beneath the impact bar 52.

The embodiment illustrated in Figure 4 differs from that of Figure 3 only in the fact that the flange 21 is extended beyond the reinforcing bar 22. The reinforcing bar 22 is straight throughout in this embodiment.

Finally in the embodiment illustrated in Figure 8, which has a projecting rim 30 and a flange 21, the reinforcing bar 22 is constructed to provide an impact bar 52 parallel to the body of the container adjoining this.
