Abstract

The reinforced unit is fitted to a large refuse bin, which has a pin receiver (28) and a pin unit (29) on opposite side walls, passing under the outwardly projecting and downward-cropped edge (7) of the body. The pin unit is considerably wider in the upper region which locks under the edge, being at least twice the width that it is in the lower region at the height of the pin receiver.

Description

I. Field of application

The invention relates to so-called garbage bulk containers.

II. Technical background

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

The emptying takes place in that on the outside of two opposite Side walls of the container projecting outward receiving pin are arranged by two fork-shaped receptacles of the evacuation vehicles taken and thus the entire container lifted, tilted and is emptied. Accordingly, the receiving pin must be very stable be formed and connected to the container. For reasons of emptying process the receiving pins must be approximately in the middle of the front side Walls are located, so an area of usually thin-walled and without larger stiffeners is formed.

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

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

However, it has been shown that z. B. due to incomplete filling of Container, however, in particular with very high density materials, it on the inner Support of the pin receiving by the filling material is lacking and thereby can come to deformations 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 pin to the container at the lowest possible weight and installation costs and size of the pin unit is achieved, as well as a forwarding the forces in the most stable zones of the container.

b) Solution of the task

This object is achieved by the characterizing features of claims 1 and 13 solved. Advantageous embodiments will be apparent from the dependent claims.

Due to the broadest possible training of the upper, in particular the edge interlocking, Range of the pin unit and / or from the central socket, which represents the receiving pin, leading away particular radial ribs can force from the middle socket to the outer ends of the Upper area are transmitted obliquely upwards and thus to the very stable trained container lids out. This applies even more to all forces that steeper upwards.

Therefore, the transition between the wide, upper area and the narrower lower area either V-shaped or T-shaped with strongly rounded Transition designed, wherein preferably the radially obliquely upward Ridges are directed tangentially to the transition radius of the outer wall.

In addition, preferably vertical and / or horizontal ribs in the cup-shaped, with the open side mounted to the carcass, part arranged, the run between the socket and the outer edge of the middle part and both with the top as well as with the bottom edge and / or other ribs Have connection.

For the purpose of screwing the impact points of the radial ribs with formed thickened the outer edge of the pin unit, in particular from Rim set back slightly into the ribs and used to screw in self-tapping screws or have for this purpose already preformed, towards the open side of the unit open, blind holes.

For example, a grid can be created by the horizontal and vertical ribs arise, with a socket in one of the resulting compartments is centered, and in particular its corners is radially ribbed, in particular Also a horizontal and vertical rib reaches this socket.

The in the central bush made of plastic inserted metal reinforcement in Shape of a piece of pipe is inserted into the socket just fit and is supported in the mounted state on its outer front side on the inner surface the continuous outer wall of the unit from and on its inner end face the wall of the corpus.

In addition can - viewed in the side view, ie viewing direction transverse to the pin - The transition from the above pin in the outer wall surface of the Be formed unit obliquely over to improve the application of force by means of the ribs.

To further stiffen the upper area, the outer wall initially points a bend on the lower free end of the downward facing Edge of the body can be applied and positively locking forces on this support can transfer.

In addition, the upper part of the unit can be inserted by inserting one in the horizontal direction, So the width of the upper part extending, metal part done, either a pipe, an open profile or a flat material, then with lying cross-section.

Such reinforcement can be accommodated in a corresponding receiving space of the open back of the cup-shaped pin unit are inserted, wherein then, however, the need exists in this area the vertical or oblique to interrupt upwardly extending ribs which serve to reinforce which drastically worsens stabilization by the ribs.

Alternatively, such a reinforcement in the longitudinal direction of the upper part are inserted through an end opening in the upper part, before the assembly of the pin unit to the container. In this case, the insertion opening placed so high that they are below the bent after assembly Rand disappears and is therefore no longer visible and accessible.

Another possibility is to interpose a lying sheet, an angle profile or a downwardly open U-profile between the Interior of the downwardly open edge and there inserted from below Top of the pin unit, which according to the wall thickness of this Material needs to be sized smaller.

The width of the upper part is chosen as large as possible, and reaches into Practice best to appropriate cross braces in the interior of the after bottom open edge, for example, in the shape of the left and right outside the end wall existing handles or receiving openings for pluggable Handles in the edge are present.

In a V-shaped unit, the opening angle of the V is in the range above the Spigot preferably chosen so that in this area the outer edge the line between the center of the pin and the free outer end of the pin upper part, so the upper corners of the unit, lies. The outer edge is at all designs without kink and with the largest possible rounding in the supervision Equipped to equip the power line in the longitudinal direction of the edge favor and hinder its buckling.

If - especially without reinforcement of the upper area by a horizontal Metal part - a further stabilization especially of the double cranked edge should be achieved, so in the width range of the pin unit one or several stiffening webs are arranged in the edge 30.

In these places, the upper, pushed under the edge area of the pin unit do not reach to the top of the groove on the edge, but here must leave appropriate, open at the top, gaps.

For this purpose, the upper part of the pin unit on the one hand and the Edge of the body on the other hand in the longitudinal direction alternately vertically have running transverse webs, or these stiffening webs can even are at the same longitudinal positions, but fill the z. B. rectangular Cross section of the edge only halfway, in the form of a triangle.

As shown in FIGS. 2a-c, the side wall 25 of the body 1 ends at the top in one double outwards downwards bent edge 7, which is thus a horizontal after outside facing connecting leg and one at the free end after pointing down, freely ending below and running in the distance to the side wall includes vertical leg.

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

In the plan view of FIG. 1 it can be seen that this edge 7 substantially goes over the entire width of the side wall 25, but the interior through mounting holes 13, the pairs in the left and right end are arranged and serve the insertion of stakes 6, interrupted.

The pin unit 29 extends therebetween throughout the remaining one Width and lies 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 at the bottom Edge 7 pointing groove bottom.

Screws 43 are from the inside of the wall 25 through it screwed in and end in blind holes 34 of the pin unit 29, as for Body open, cupped, ribbed, outside of a closed Outside wall 40 framed, plastic injection molded part is designed.

In the middle of the protruding downwards leg of the T-shape of the Unit 29, the central sleeve 30 is formed integrally with the unit 29, in which inserted from the open side of the reinforcing metal tube 31 fit is.

Of the bush 30 rich - as the rear view of FIG. 3 shows - radial Ribs 32 a, b, c .. outward, which meet the edge 33, the one-piece and is formed cranked relative to the outer wall 40.

In close to the connection points between the edge 33 and the radial Ribs 32, which are formed thickened, the blind holes 34 are formed.

In addition, as shown in the left half of FIG. 3, vertical Ribs 35 from the upper edge 33 to the lower edge 33 continuously available be, e.g. in the area between the sleeve 30 and the vertical outer Edge.

The obliquely upwardly extending from the sleeve 30 ribs 32 a, c are the am most loaded ribs and go tangentially into the edge at the inner radius at Transition between vertical middle leg and transverse upper Area of the unit 29 over and from there to the upper inner corners the unit 29 and the edge 33 there.

For further stabilization, a profile 37 or a flat iron 36 in the longitudinal direction, that is to say the width, of the upper part 29a of the unit 29, which preferably extends to the inner surfaces of the front edges of the extends the upper area.

Fig. 2a shows an angle profile 37 ', which on the outer surface of the side wall and is arranged under the transverse leg of the side edge and positively merely by the upper edge 33 of the units pressed from below 29 is held.

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

3 shows in the right part of an open towards the rear receiving space 38 for a flat material 36, which lies flat with in the mounted state Cross-section is inserted, since the bending forces then in the direction of its largest Cross-sectional extension occur.

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

Remedy here creates the drawn in Fig. 2a sheet 26, which according to Figure 2c inserted in its longitudinal direction in apertures 38 'in the ribs must be, thus surrounded on all sides by the ribs 32, 35 are and thus their stability only slightly influence.

For insertion, the edge 33 of the unit 29 has an end opening 39, which is preferably so high that it is higher in the assembled state than that lower edge of the edge 7 and thus neither accessible nor visible.

Accordingly, the unit can be assembled by first placing the metal tube 31 is inserted from the open back into the socket 30, previously or thereafter in its longitudinal extent the profile 37 or flat material 36 of the frontal opening 39 is inserted into the unit 29 and thereafter the unit 29 is inserted with its upper portion under the edge 7 and in this Position screwed by means of screws 43 from the inside of the side wall 25 becomes.

In addition, or instead, another stiffening profile 37 'between the Unit 29 and the edge 7 is to be inserted, as in Fig. 2a, this is before or when inserting the unit 29 under the edge at any time.

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

In this case, at one or more points in the longitudinal extension of the edge 7 stiffening webs 42 between the outer free around the leg of the edge. 7 arranged on the side wall. Only in the area between these stiffening webs 42 reaches the top 29a to the very top in the interior of the Groove of the edge 7 in, which affects its stability, however.

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

The inner wall 25 indicative, diagonally divided, triangular upper area is available for corresponding triangular stiffening webs 42 of the edge 7, while at the same position or even the other offset the lower triangular region for stiffening webs 42 'of the units 29 is available, the upper edge, however, in the area between the webs 42 to the side wall 25 may extend.

There are then also stiffening webs 42 'with completely the interior of the Randes filling, so z. B. rectangular, cross section possible.

Furthermore, the side view of Fig. 2d shows that the outer wall 40 from the neck of the pin (28) not at right angles, but at an obtuse angle can run to the outside, so that a tapered on the pin 28 cone, to improve the force transmission, especially down the edge 33 ends and at the top of the upper portion 29 a, which under the edge 7 of the body 1 can be pushed.

Furthermore, it can be seen in Fig. 2a in one of the screw 43 that the thickened screw receptacle of the unit 29 on the open back of the Unit continues out cone-shaped, for centering in a local hole of the Wall 25 of the corpus 1.

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

In the interior of the unit are horizontally extending ribs 32 l - q and vertical extending ribs 35, 32 b, arranged, one horizontal and one vertical Each rib point to the center of the socket 30, as their crossing point acts. From this bushing 30 diagonal ribs are sufficient 32a ', 32c' ... diagonally outwards to the adjacent crossing points of horizontal and vertical ribs to which they pass but not above out.

In the lower area are thickened screw receptacles - again near the encircling Edge 33 - arranged on the one hand in the horizontal rib, the on the center of the bushing 30 and on the other hand in the vertical ribs, the side next to the socket, about in the middle between the socket and the lateral edge 33, run down, of which only one available is.

In the upper area, a horizontal rib 32q extends at the level of the lower one Edge of the upper area, and goes into the edge 33 tangentially at the site over, on which this approximately horizontally reaches the front side of the unit 29.

Another horizontal rib 32p is spaced above it but even deeper than the return in the outer skin 40, which is free after supported down leg of the edge.

About this horizontal rib 32p go upwards only the two sides of the Bushing 30 extending vertical ribs 35 or no vertical rib out, while the middle vertical rib 32b merges into and ends in it.

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

In addition, in the course of the horizontal rib about midway between vertical plane of symmetry of the unit 29 and the outer front end the upper portion 29a another screw as a thickening of the Rib 32 may be formed as shown in the left half of Fig. 4.

One of the screw receptacles, preferably one of the lowest-lying Screw, is over the back protruding and in particular conical formed above as centering, as explained with reference to FIG. 2a.
