Abstract

In the case of an underfloor collecting container (1), with a housing (7) which can be fully retracted into the floor and which has a square cross section, a floor frame (10) at the lower edge of the housing (7), a housing (7) which closes at the bottom and can be pivoted stored bottom flap (11), and with a tension element (14), by means of which the bottom flap (11) can be moved from a hanging open position into a raised, lying closed position, the invention proposes that two mutually opposite, as inner walls ( 9) designated walls of the housing (7) have a distance from one another which is less than the distance between the two outer sides, which the base frame (10) has where it runs along these two inner walls (9), and that the base frame ( 10) each has a recess on the outside in front of an inner wall (9), and the tension element (14) extends through this recess in an upright direction.

Description

The invention relates to an underfloor collecting container according to the preamble of claim 1.

Such underfloor collecting containers are known from practice. They have a capacity of several m ³ . In contrast to collecting containers, which are only partially sunk into the floor and which have a housing with a round or polygonal cross section, the walls of a generic underfloor collecting container have a comparatively large width. For emptying, the underfloor collection containers are raised in a manner known per se. First of all, the bottom of the housing remains closed in that the existing one or more bottom flaps, which the housing has, is or are held in their lying-aligned closed position by means of a pulling element. Only then, when the underfloor collection container has been lifted over, for example, the trough of a truck, is the bottom flap pivoted into its downward-hanging open position by influencing the pulling element, so that the contents of the container support gravity and flow out of the housing of the underfloor collection container. At the lower edge of the housing, a circumferential floor frame is provided, the four sections of which along the respective housing walls are designed as a hollow profile or as an angle profile. This floor frame and its stability ensure that, despite the comparatively large width dimensions of the walls of the square housing, it can be ensured that deformations of the housing are avoided which would otherwise hinder or make impossible a lowering of the housing again into the floor.

The invention has for its object to ensure as complete an emptying as possible and a problem-free mobility of the bottom flap in a generic underfloor collecting container.

This object is achieved by an underfloor collecting container with the features of claim 1. Advantageous configurations are described in the subclaims.

In other words, the invention proposes several measures which, as a result, result in the tension element being able to run outside the housing. As a rule, several pulling elements are used, for example one pulling element on each of the two opposite sides of the bottom flap, so that the underfloor collecting container has two pulling elements. And often the housing has two bottom flaps that open in opposite directions, so that the underfloor collecting container has four pulling elements in these cases.

The course of the pulling element outside the housing prevents parts of the container from getting caught between the pulling element and the container wall. In this way it is ensured, on the one hand, that no constituents of the content which have got caught in this way remain in the container when the underfloor collecting container is emptied. Accordingly, an optimally complete absorption capacity of the underfloor collecting container is ensured after emptying. This also ensures that the The mobility of the tension element is not impaired by the fact that portions of the container content can get jammed between the tension element and the container wall. In this way, on the one hand, problem-free emptying of the container is possible within an optimally short time, namely by allowing the bottom flap to be guided quickly and completely into its maximum open position, and this unrestricted mobility then also ensures that the bottom flap is completely in its place Closed position can be moved so that when the next planned emptying of the housing, no unwanted gap can arise in the area of the bottom flap, which could lead to a premature, undesirable loss of parts of the container contents before the container via the mentioned receiving device, for example the trough Trucks that have been brought.

The underfloor collection containers are typically received in the floor inside an outer container. In order to prevent the pulling element from being damaged or deformed when the housing is lifted out or then lowered again into the outer container, it is proposed that the pulling element does not run outside the base frame. Rather, the base frame has recesses through which the tension element extends in the upright direction. The outer circumferential contour of the base frame thus acts like a spacer, which reliably prevents the pulling element from hitting the inside of the outer container even when the underfloor collecting container is in a pendulum motion.

In favor of the largest possible receiving volume that the underfloor collecting container is to provide, it can be provided that the walls of the housing basically connect to the outer surfaces or outside of the floor frame. Where the tension element is provided, however, the two opposite walls of the housing close not on the outside of the floor frame, but rather further inwards, so that the distance between these two opposite walls is less than the distance between the two outer sides of the floor frame in this area. Because of this inward arrangement, these two walls are referred to as inner walls in order to distinguish them purely linguistically from the other two walls of the housing, which can connect to the floor frame on the outside, for example.

It can advantageously be provided that the two inner walls do not, for example, stand in the middle from above on the respective sections of the floor frame, but rather that they connect to the inside of the floor frame. This supports the simplest possible assembly of the housing, in that the inner wall in question does not need to be welded to the base frame, for example, but instead can be screwed or riveted to the base frame, for example.

The tension element can advantageously be designed as a linkage, specifically in the form of a flat profile. Compared to, for example, a chain or in the form of a linkage with the same cross-sectional area, a particularly flat design of the tension element can be made possible, so that it can run as flat as possible along the inner wall of the container, which is advantageous in terms of protection against possible damage is.

The bottom flap can advantageously be trough-shaped and in this case connect the pulling element on the inside to the peripheral edge of the bottom flap. In this way, there is the possibility of designing the bottom flap to have a particularly large area and thus to enable the housing on its underside to be closed in a particularly reliable, tight manner.

It can be particularly advantageously provided that the recesses in the base frame, through which the tension elements run, are not simply designed as indentations in the contour of the base frame, but rather as slots, which are thus surrounded all around by the material of the base frame. In this way, the required stability can be ensured even with a comparatively low material thickness of the base frame, which is necessary in view of the square container cross-section under correspondingly relatively wide walls in order to reliably rule out undesired deformation of the walls. For example, the four frame sections, which together form the base frame, can each be designed as a profile strip, that is to say they have an angled or curved cross-sectional profile. For example, such a section can be produced as an edge profile rail, that is to say not by the extrusion process, but rather by being folded from a flat sheet metal blank. In comparison to a solid, for example rectangular, cross-sectional profile, the section of the floor frame has a high bending stiffness with a comparatively low material thickness.

An exemplary embodiment of the invention is explained in more detail below on the basis of the purely schematic representations. It shows

Fig. 1

a perspective view of an underfloor collecting container, with closed bottom flaps,

Fig. 2

a side view of the container of Fig. 1 , with closed bottom flaps, and

Fig. 3

a side view similar Fig. 2 , but with the bottom flaps open.

In Fig. 1 an underfloor collecting container 1 is shown in its use position, in which it is located, for example, inside an outer container, which is not in the drawing is shown and is sunk in the ground. At the top, on the floor surface, a walkway platform 2 is visible to the user, which can be entered, so that the user can operate a throw-in column 3 and, for example, throw waste into the throw-in column 3. For this purpose, a flap 4 is opened, which is then spring-loaded in it Fig. 1 recognizable swiveling closed position.

At the upper end of the insertion column 3, two retaining rings can be seen, one being designated as a support ring 5 and one as an actuating ring 6.

Below these visible components, the underfloor collecting container 1 has a housing 7 below the walkway platform 2, which has a square cross section and has two so-called outer walls 8 and two so-called inner walls 9. At the lower end, the housing 7 has a circumferential bottom frame 10, and two bottom flaps 11, which close the housing 7 towards the bottom.

How from Fig. 1 It can be seen that the outer walls 8 connect to the outside of the floor frame 10 and thus allow a maximum receiving volume of the housing 7. The inner walls 9, however, adjoin the floor frame 10 offset further inwards, in the exemplary embodiment shown to the inside of the floor frame 10.

The base frame 10 is designed as an edge profile rail, so that it has a high bending stiffness with a comparatively low material thickness. Outside, in front of the inner wall 9, the floor frame 10 has two slots 12 which penetrate the floor frame 10 in the upright direction, so that tension elements 14 can accordingly extend in the upright direction through these slots 12 and thus through the floor frame 10.

The tension elements 14 are each connected to a bottom flap 11 at the bottom, the bottom flap 11 being trough-shaped and the tension element 14 connecting from the inside to the circumferential edge of the bottom flap 11, so that only hinge elements 15 can be seen from the outside, for example rivets or screws which serve to attach the tension element 14 to the bottom flap 11 and at the same time form a hinge point.

The tension elements run upwards and also connect there in an articulated manner to a cross member 16 via further hinge elements 15. The cross member 16 is vertically movable within a guide slot 17 and is in Fig. 1 held in the upper position within this guide slot 17 by means of the pulling elements 14: The underfloor collecting container 1 stands, as explained, with its lower end, namely with the two bottom flaps 11, on the bottom surface of the outer container not recognizable in the drawing, so that the bottom flaps 11 remain in their horizontal closed position in this way. The tension elements 14 are designed as flat bars, so they can also transmit compressive forces and thus support the cross member 16 so that it remains in the upper region of the guide slot 17.

Fig. 2 shows the underfloor collecting container 1 in a side view of the opposite, in Fig. 1 hidden side. The underfloor collecting container 1 is no longer in the floor, in particular no longer in the outer container, but in a raised state. The entire underfloor collecting container 1 can be raised via the support ring 5. First of all, the actuating ring 6 is like from Fig. 2 visible, also raised, and above the support ring 5 upwards. One is off Fig. 2 Provided not visible connecting element between the actuating ring 6 and the cross member 16, for example a chain 18, by lifting the actuating ring upwards, the chain 18 is tightened and the traverse 16 pulled up so that it is out in her too Fig. 1 apparent raised position remains. The tension elements 14 no longer support the cross member 16, as shown in FIG Fig. 1 was the case, but transmit tensile forces to the bottom flaps 11, so that the bottom flaps 11 are held in their lying, closed position.

Fig. 3 shows the underfloor collecting container 1 in an arrangement after it in his Fig. 2 apparent arrangement has been pivoted via a waste receiving device, for example over the trough of a truck. In order to be able to empty the housing 7, it becomes as if Fig. 3 can be seen, the actuating ring 6 lowered until it is at the same height as the support ring 5 and in Fig. 3 the support ring 5 covered. Supported by gravity, the crossbeam 16 is thereby lowered, which is pulled downward by its own weight, by the tension elements 14 and the bottom flaps 11, and by the waste loading on the initially closed bottom flaps 11. Fig. 3 shows that the traverse 16 has lowered to the lower end of the guide slot 17. A chain 18 is visible through the guide slot 17, which connects the cross member 16 to the actuating ring 6, by this chain 18 connecting to the rod, at the upper end of which, as seen from Fig. 2 can be seen, the actuating ring 6 is located.

The comparison between the Fig. 2 and 3rd makes it clear that the length of the slots 12 in the floor frame 10 enables the movement of the tension elements 14 in order to allow their angular adjustment between the closed position and the open position of the floor flaps 11.
