Description

field of invention

The invention relates to a container shoe for attachment to a roller of a roll-off container and a method for its use.

Background of the Invention

Roll-off containers, which are also referred to as roll-off containers, can be picked up by a vehicle and z. B. after a transport to another position, parked. To facilitate the parking process, roll-off containers have rollers on the underside. The rollers are usually cylindrical or have a cylindrical rolling body. With the rollers, the roll-off container can be moved when it is parked on the rollers. However, e.g. B. road surfaces, sidewalks and the like are loaded or damaged by the rolling process. Another problem is that the wheels can sink in when parked on soft ground. On the one hand, this can impair the even filling of the roll-off container, especially in the case of liquid or bulk goods; B. Sand wear out the roller bearings quickly.

It is therefore common practice to protect the subsoil by placing wooden panels, scaffolding planks or similar objects under the container. Out of U.S. 2017/0247185 A1 and DE 10 2005 056 635 A1 conditions for supporting a roll-off container are known. However, when the roll-off container is set down, frequent readjustment of these objects is then necessary, so that a user often has to get out of the vehicle or at least one helper is required when setting down or repositioning the container. This increases the expenditure of time and money.

The object of the invention is therefore to provide a device that facilitates the setting down of roll-off containers.

The object is solved by the subject matter of the independent claims. Advantageous developments are the subject of the dependent claims and the following description and figures.

Description of the invention

According to one aspect of the invention, a container shoe is provided for attachment to a roller of a roll-off container. The roller can be cylindrical or have a cylindrical, in particular circular or rotary cylindrical, rolling body with a lateral surface and two base surfaces, also referred to here as end faces or end faces. In the following, the term “roller” can therefore refer in particular to the cylindrical rolling body. Typically, such rollers or cylindrical rolling bodies have a diameter of greater than or equal to 100 mm, in particular greater than or equal to 150 mm.

The container shoe comprises an underside with a ground contact surface and an upper side with a roller contact surface, with a roller receiving device being arranged on the upper side, which is designed to hold at least part of the roller, i. H. in particular at least a part of the cylindrical rolling body.

With the container shoe, the invention provides a device that can be attached to a roller of a roll-off container in order to increase the contact surface of the roll-off container on the ground. To do this, the container shoe is placed against the roller with the roller contact surface. The container shoe takes up at least a part of the roll with the roll receiving device.

In this case, the roller receiving device can also be used to attach the container shoe to the roller, d. H. be formed in particular on the cylindrical rolling body. The roller receiving device is preferably designed to receive at least part of the roller or the cylindrical rolling body in a form-fitting manner. The positive locking preferably acts radially to the roller axis, i. H. in particular, the positive locking blocks movements in one or more directions perpendicular to the roller axis. This ensures that the container shoe can be attached to a container roller quickly, easily and securely.

The roller contact surface is arranged on an upper side of the container shoe, it being possible, for example, for a part of the roller contact surface to extend over a part of the roller receiving device.

The ground contact surface is arranged on the underside of the container shoe, which faces the ground when the roll-off container is set down on the container shoe. Accordingly, when the roll-off container is set down on the container shoe, the upper side faces away from the ground. The container shoe is designed with the ground contact surface to increase the contact surface of the roll-off container. So the container shoe, z. B. supplement or replace the surface with which the roller rests on the ground. For this purpose, the container shoe can have an opening in one example, with a part of the lateral surface of the roller continuing to rest on the ground after the container shoe has been attached can be set. Away from the opening, the ground contact surface can then supplement this part of the lateral surface as an additional bearing surface.

In another embodiment, the roller can be completely shielded from the ground by the container shoe, so that the ground contact surface alone represents the bearing surface of the roll-off container or is arranged completely between the ground and the roller. In this way, the roll-off container can be parked selectively and by a single user. A readjustment after attaching the container shoe is not necessary. The effort and costs for the parking process can thus be reduced.

In preferred embodiments, the ground contact area is larger than the roller contact area. The roller contact surface is the bearing surface of the roller on the container shoe. If the roll-off container is set down without a container shoe attached to the roller, at least part of this contact surface of the roller would contact the ground. A ground contact area that is larger than the roller contact area therefore increases the contact area and thus improves the weight distribution of the roll-off container on the ground. This effectively prevents the risk of damage to the subsoil or sinking into soft subsoil.

According to a preferred embodiment, the roller receiving device is designed to be slid over the roller or the cylindrical rolling body in a direction parallel to an axis of rotation of the roller.

According to this embodiment, the container shoe can be attached to the roller with the roller receiving device at the edge of an end face of the roller or of the cylindrical roller body. The container shoe with the roller contact surface can then be pushed over at least a part of the outer surface of the roller or the cylindrical rolling body until the roller completely contacts the roller contact surface.

A further possibility is that the roll receiving device comprises two half-shells which at least partially enclose the roll or the cylindrical rolling body, e.g. B. using a joint connection. In this example, an opening can also be provided between the half-shells, through which a part of the outer surface of the roll is exposed and can make contact with the ground when it is set down. As a result, the ground contact surface complements the bearing surface of the roller.

However, this does not rule out the possibility that no opening is provided and the half-shells, after being attached to the roll, completely shield the roll from the ground when the roll-off container is set down.

In preferred embodiments, the roller receiving device comprises at least one roller receiving element which is designed to at least partially encompass the roller or the cylindrical rolling body, in particular part of a lateral surface of the roller or the cylindrical rolling body. The roll receiving device can also consist of the at least one roll receiving element.

The roller receiving element preferably has a wall in the form of an arc of a circle for laying against a lateral surface of the roller or of the cylindrical rolling body, i. H. the wall of the roller receiving device can essentially correspond in shape to a part of the lateral surface of the roller, d. H. in particular be designed to correspond in shape to a part of the lateral surface of the cylindrical rolling body. Preferably, the arcuate wall extends over more than half of a circle.

With the wall in the shape of a circular arc, a receiving contour designed to match the lateral surface can be provided for the roller. The wall can reduce a rolling movement of the roll in the roll receiving device and improve the seat of the container shoe on the roll. Because the wall extends over more than half of a complete arc of a circle, an advantageous positive fit of the roller receiving device is achieved.

The roller receiving element can, for. B. be formed as a projection on the top of the container shoe, wherein the projection has a, preferably centrally arranged and / or open at the top, recess, which for receiving a part of the roller or the cylindrical rolling body, in particular at least partially complementary or shape-corresponding to the outer surface of the roller or the cylindrical rolling body.

Preferably, at least two roller receiving elements as described above are provided on the container shoe, which are arranged at a distance from one another. In particular, the two roller receiving elements can be arranged as mirror images on opposite edges or outer edges of the upper side, in particular on two edge sections of the roller contact surface arranged opposite one another. The role or the cylindrical rolling body can be between tween the roller receiving elements extend, wherein the roller receiving elements, the recorded role or the cylindrical rolling body at least partially, preferably more than half the circumference, surround. Furthermore, the roller receiving elements can extend over the entire upper side from one edge of the container shoe to an opposite edge of the container shoe.

It is also possible that a roller receiving element or the projection is formed by at least two fingers arranged on opposite sides of the roller or the cylindrical rolling body, which extend radially outwards from the top and each part of the outer surface of the roller or the rolling body embrace. The mutually facing inner sides of the fingers can each be designed to complement or correspond in shape to a part of the outer surface of the roller or the rolling body. Preferably the fingers extend radially beyond the axis of rotation of the roller. In this way, an advantageous form fit around the roller is achieved through the interaction of both fingers, which ensures that the container shoe is held securely on the roller. Preferably, the fingers are mirror images of each other.

In preferred embodiments, the roller receiving device or at least one roller receiving element has a stop for an end face of the roller or the cylindrical rolling body.

The stop may be located at only one edge of the roller contact surface. At this edge, the role can then only be pushed up to the stop. The stop forms a positive fit in a direction parallel to the axis of rotation of the roller, starting from the roller contact surface, for the end face of the roller or rolling body that rests against it. A defined arrangement of the container shoe is thus provided by the stop when it is attached to the roller. This can simplify the attachment of the container shoe, since no adjustment of the container shoe on the role is necessary and z. B. the slipping of the container shoe is prevented in the push-on direction.

An outer edge surface of the stop arranged transversely to the ground contact surface can, for example, merge flush into the roller receiving device. An inner edge surface arranged transversely to the ground contact surface can also merge flush into the roller receiving device or border on a step.

In preferred embodiments, the roller contact surface is curved inwards at least in sections, preferably at least partially in the shape of a cylinder jacket.

An inwardly curved roller contact surface reduces rolling movements of the roller on the roller contact surface. Furthermore, the inwardly curved roller contact surface is larger than a planar roller contact surface. As a result, an improved load distribution can be achieved and the hold of the roller can be increased due to increased frictional forces.

The ground contact surface is preferably formed flat.

A flat ground contact surface increases the stability of the roll-off container when it is placed on the container shoe.

According to a further example, the container shoe can have at least one base plate, with the roller contact surface and the ground contact surface being arranged on two opposite sides of the base plate.

The base plate can be angular, preferably essentially square, more preferably rectangular. The corners can be rounded. Furthermore, the base plate, possibly together with the roller receiving device, in one piece, z. B. by casting, or multi-piece. In the multi-piece form z. B. the roll receiving device can be manufactured as a separate component and connected to the base plate.

The container shoe according to the invention has a locking device for locking the roll in the roll receiving device.

The container shoe is then secured to the roller. The risk of the container shoe slipping off the roller can thus be reduced.

In a preferred embodiment, the locking device is movably articulated on the container shoe. According to the invention, the locking device is designed to switch between an open state and a closed state, which secures the roll axially to its axis of rotation when it is arranged in the roll receiving device. In the open state, the roll can be pushed onto the roll receiving device or removed from it. In this way, a locking device that is easy to operate and closes securely is provided.

If two roller receiving elements are provided on opposite edge portions of the roller contact surface, preferably only one of the roller receiving elements has the locking device. The stop can then be provided on the other roller receiving element, for example. However, both roller receiving elements can also have a locking device, in which case a stop would then possibly be unnecessary.

Furthermore, the locking device can have, for example, a latch and a safety device, the latch preferably being mounted on the at least one roll receiving device such that it can rotate about an axis parallel to the roll contact surface.

The bolt can be brought into the closed state already explained above, for example, by rotating it about the axis parallel to the roller contact surface. The locking device can be used to fix the bolt in the closed state. In order to switch the bolt from the closed state to the open state, the safety device must then be unlocked beforehand.

The backup component can e.g. B. include a bolt for fixing the bolt and a cotter pin for fixing the bolt to the locking device.

In further embodiments, the container shoe can have a transport aid for transporting the container shoe, in particular a carrying strap, a rope or a handle.

This simplifies the transport of the container shoe by a user.

The container shoe can e.g. B. be formed of metal or a natural or artificial polymeric material. Preferred materials are natural and artificial elastomers such. B. vulcanizates of natural rubber and silicone rubber, and thermoplastic and thermosetting plastics. Polyethylene-based materials, in particular high molecular weight polyethylene (PE-HMW) such. B. PE 500 or higher, have proven to be particularly advantageous.

In preferred embodiments, the base plate of the container shoe or the ground contact surface has a width in a range from 80 mm to 500 mm, preferably 180 mm to 400 mm, more preferably 300 mm to 380 mm, most preferably 350 mm to 360 mm.

Parallel to the axis of rotation of the inserted roller, the base plate or the ground contact surface can have a length in a range from 200 mm to 400 mm, preferably 250 mm to 350 mm, more preferably 300 mm to 325 mm.

The height of the container shoe as the sum of the heights of the base plate and the roller receiving device can be selected in a range from 85 mm to 250 mm, preferably 100 mm to 200 mm, more preferably 150 to 180 mm.

In a further aspect, the invention relates to the use of a container shoe according to the above description for enlarging a contact surface of a roll of a roll-off container.

Advantages and effects as well as further developments of the use of the container shoe result from the advantages and effects as well as further developments of the container shoe described above. In order to avoid repetition, reference is therefore made to the previous description in this regard.

According to a further aspect, the invention relates to a method for setting down a roll-off container on a substrate, the method having at least the following steps: lifting the roll-off container in such a way that at least one roll of the roll-off container is lifted; Attaching a container shoe according to the preceding description in such a way that the roller contact surface rests against part of the lateral surface of the roller and the ground contact surface is directed towards the ground; and placing the roll-off container on the container shoe, with the ground contact surface being arranged between the roll-off container and the ground.

Advantages and effects as well as further developments of the method result from the advantages and effects as well as further developments of the container shoe described above. In order to avoid repetition, reference is therefore made to the previous description in this regard.

Detailed description of exemplary embodiments

The container shoe according to the invention is described below 1 denoted by the reference numeral 10 in its entirety.

The container shoe 10 according to the invention has an underside 12 and an upper side 14 . The bottom 12 and the top 14 can be two opposite sides of a base plate 36 .

On the underside 12, the container shoe 10 has a ground contact surface 16, which can be flat. The ground contact surface 16 is intended to be placed on a subsurface when the container shoe 10, as described below in 2 shown attached to a cylindrical roller 52 with a roll-off container 50 .

The container shoe 10 has a roller contact surface 18 and a roller receiving device 20 on the upper side 14 .

The roller contact area 18 is smaller than the ground contact area 16. Further, the roller contact area 18 is inward, i. H. concave, curved, in this example at least partially in the shape of a cylinder jacket. With this shape, the roller contact surface 18 can be applied partially around an outer surface 54 of the cylindrical rolling body of the roller 52. This makes it more difficult for the roller 52 to roll off.

Further, the roller contact surface 18 may extend from an edge portion of the base plate 36 to an opposite edge portion of the base plate 36 .

In this example, the roll receiving device 20 comprises two roll receiving elements 22 which are arranged in two opposite edge sections on the upper side 14 of the base plate 36 . Both roller receiving elements 22 form a projection extending vertically upwards from the upper side with a central part-circular or part-cylindrical recess 23, which forms a receiving opening for sliding over the cylindrical roller 52 in a direction parallel to an axis of rotation 40 of the roller 52.

2 shows the container shoe 10 after it has been attached to a roller 52 with a cylindrical rolling body of a roll-off container 50, which is only partially shown here . As a result, the roller 52 is held in a form-fitting manner transversely to its axis of rotation 40 by the roller receiving elements 22 . How using the outbreak in 2 is shown, the roller receiving elements 22 can each have an arcuate inner wall 34 in the region of the recess 23, which can be applied in the circumferential direction of the roller 52 to the outer surface 54 of the roller 52, ie in the narrower sense of the cylindrical rolling body. It can be clearly seen that the bearing surface of the roller 52 is increased by the container shoe 10.

The roller receiving elements 22 can receive the roller 52 from an end face of the roller 52 via the receiving opening defined by the recess 23 . When the container shoe 10 is attached, the roller receiving elements 22 are then moved or pushed onto the roller 52 along the lateral surface 54 of the roller 52 in the direction of the axis of rotation 40 of the roller 52 .

A stop 24 can be arranged on at least one side of the roller contact surface 18 . You can continue, as in the example in 1 and 2 shown, the roller receiving device 20 or one of the roller receiving elements 22 have the stop 24.

The stop 24 provides a stop surface against which an end face of the roller 52 strikes when the container shoe 10 is pushed onto the roller 52 . In the direction of the axis of rotation 40 of the roller 52, the stop 24 limits the freedom of movement of the roller 52 and defines an end position of the roller 52 or the container shoe 10 when the container shoe 10 is pushed on.

The stop 24 can be flush with an outer edge of the base plate 36 . Furthermore, the stop 24 can protrude from the roller contact surface 18 and, in particular, at least in sections from the inner wall 34 in the shape of a circular arc in the region of the roller receiving device Device 20 and the roller receiving element 22 extend radially inwards.

In the example shown, the container shoe 10 has a base plate 36 with a length parallel to the axis of rotation 40 of the inserted roller 52 of approximately 300 mm. The width of the base plate 36 transverse to the axis of rotation 40 of the roller 52 is approximately 360 mm. The total height from the ground contacting surface 16 to the top of the roller receiving elements 22 is approximately 165 mm. The two roller receiving elements 22 each have a width parallel to the axis of rotation 40 of the roller 42 of approximately 40 mm. The recess 23 of the roller receiving elements 22 has an inner diameter of about 164 mm, in the area of the stop 24 of about 144 mm, i. H. the stop 24 extends radially inwards from the inner wall 34 of the recess 23 by up to 10 mm in each case. These dimensions have proven advantageous for many common roll-off containers.

A suitable material for the production of the container shoe 10 has here z. B. polyethylene, especially PE-HMW 500 proven.

For transporting the container shoe 10, the container shoe 10 can have a carrying strap, a rope or the like (not shown in the figures). The carrying strap or the rope can be attached to openings on the container shoe 10, for example on the roller receiving elements 22 or the base plate 36.

3 shows the container shoe 10 according to the invention with locking device 25, which is used to securely fasten the container shoe 10 to the roller 52.

The locking device 25 can have a bolt 26 which is movably articulated on the container shoe 10 . For this purpose, the bolt 26 can be mounted at least pivotably on the container shoe 10 via an axis 27 .

The latch 26 can switch between an open state and a closed state. In 3 the closed state of the bolt 26 is shown.

In the closed state, the bolt 26 protrudes at the edge of the roller contact surface 18 into the opening area of the recess 23 and thus extends over part of the end face of the roller 52. A roller 52, which is held by the roller receiving device 20, can be rotated in the direction of the axis of rotation 40 of the roller 52 cannot be pushed over the bolt 26 since the bolt 26 blocks this movement.

The movement of the bolt 26 between the two states can be guided. For this purpose, the bolt 26 can have a curved guide slot 30 into which an engagement element 32, e.g. B. engages a pin, which is fixed to the container shoe 10 is arranged. The freedom of movement of the bolt 26 can be adjusted by the length of the slot 30.

In the closed state, the bolt 26 can be further fixed by a safety device 28 . For this purpose, the safety device 28 z. B. have a bolt that is inserted through an opening of the bolt 26 into a further opening on the container shoe 10. A cotter pin can secure the bolt 28 to the locking device 25.

In the open state, the bolt 26 releases a roller 52 which is arranged in the roller receiving device 20 .

4 shows the container shoe 10 3 with the locking device 25 closed in a side view. In the side view it can be seen that the roller 52 rests with the end face on the right as viewed from the viewer against the stop 24 of the right roller receiving element 22 and with the left end face on the closed bolt 26 of the locking device 25 .

In 5 a flowchart with the sequence of the method 100 according to the invention for setting down a roll-off container 50 with at least one roller 52 on a substrate is shown. The roll-off container 50 can be located, for example, on a vehicle from which it is to be parked on the ground.

In a first step 102, the roll-off container 50 is raised so far that at least one roller 52 is raised. The roller 52 then preferably hangs freely in the air.

Therefore, in a second step 104, a container shoe 10 can be attached to the roller 52 in accordance with the explanations given above. Attachment takes place in such a way that the roller contact surface 18 is placed against a part of the outer surface 54 of the roller 52 .

Furthermore, the attachment can be achieved by sliding the container shoe 10 over the roller 52, e.g. H. in particular via the cylindrical rolling body. The end position of the roller 52 after it has been pushed on can be defined by a stop 24 on the container shoe 10 .

The ground contact surface 16 of the container shoe 10 attached to the roller 52 is directed downwards.

If a locking device 25 is provided on the container shoe 10, locking can take place after the container shoe 10 has been attached. So e.g. B. a bolt 26 on the container shoe 10 fix the roller 52 on the container shoe 10 axially. The bolt 26 itself can, for. B. be secured by a bolt 28 and a cotter pin.

Steps 102 and 104 can be performed for each roll 52 simultaneously and/or for each roll 52 individually.

In a further step 106, the roll-off container 50 is placed on the container shoe 10. The ground contact surface 16 of the container shoe 10 is then arranged between the roll-off container 50 and the ground. The roller 52 preferably rests on the container shoe 10 without touching the ground.

The container shoe 10 is thus used to increase the bearing surface of the roller 52 of the roll-off container 50 .

The example described above is in no way intended to limit the invention. Rather, the invention can be modified in many ways. All features of the invention described above can be essential for the invention alone or in combination with one another.
