EP3486198B1 - Device for holding a bag - Google Patents

Description

The invention relates to a device according to the preamble of claim 1 for holding a sack, in particular a rubbish sack, with a container on whose upper edge area a clamping device for stretching at least one sack is arranged.

background

From the patent EP 1 614 642 such a device is known. Clamping means, which are partially formed by a rake, are arranged at the upper edge area. The rake has several tongues, which are suitable for opening sacks of different sizes. The sack is slipped over the tongues so that it is held in place as well as possible by the stretching and maintains its stretched state while the sack is being filled.

JP-U-0627703 shows clips with clip legs at right angles to each other, whereby the clip can be opened against the force of a spring closing the clip. This allows one over the four corners bag pulled from a container can be clamped in the corners of the container.

However, this jig is not optimal. For example, if the sack has a rather small sack opening, good stretching can be achieved, but the sack is difficult to slip over the tongues and there is a risk that the sack will tear due to excessive stretching. If the sack opening is somewhat larger, the sack can be stretched easily, but the sack is not stretched sufficiently, so that the sack is not sufficiently held in the stretching device.

A device according to the preamble of claim 1 is from EP 3 078 612 A1 known.

Presentation of the invention

The object of the present invention is to provide a device of the type described at the outset, with which a sack can be stretched as simply as possible, but the sack is nevertheless firmly held.

Accordingly, the invention provides a device according to claim 1 for holding a sack, in particular a rubbish sack. The device has a container on whose upper edge area a clamping device for clamping at least one sack is arranged. The clamping device has at least one holding part for holding the rubbish bag, which is arranged on a container corner, in particular on the upper edge region of the container corner.

This has the advantage that the holding part is arranged at that position of the container at which it is least disruptive in order to insert the rubbish sack into the container or to remove the rubbish sack from the container. Furthermore, the holding part can be stably arranged in the container corner.

The holding part has a mounting part for fixing the holding part to the container. In particular is the mounting part cannot be moved relative to the container.

Furthermore, the at least one holding part has a holding structure part for receiving a rubbish bag. The holding structure part can have a hook shape, for example, so that the rubbish bag can be fastened to the holding structure part.

The holding structure part can be moved relative to the mounting part, in particular in the form of a rotational movement.

The mobility of the retaining structure part relative to the mounting part makes it easier to mount the rubbish bag on the retaining structure part or on the container. For example, the holding structure part can be moved into a first position, in which the refuse sack can be mounted particularly easily, and into a second position, in which the sack is stretched with sufficient force so that it does not fall into the container during filling. Dividing the assembly and clamping into two steps simplifies the handling of the clamping process.

Furthermore, the device described can also be used to compensate for manufacturing tolerances that lead to different circumferences of the bag opening. Due to the mobility of the clamping elements, the clamping device can easily be adapted to the respective circumference of the bag opening.

This design also makes it easy to remove the bag from the clamping device. In a first step, the movable support structure part is moved to the first position in order to release the bag tension. The bag can then be easily removed from the clamping device.

The retaining structure part can be moved at an angle to the side walls of the container (5) adjoining the container corner, or the retaining part (3) is designed in such a way that it only extends within a container corner radius of at most 10 cm.

The clamping device advantageously has at least two, in particular at least four, holding parts, in particular the holding structure parts of the individual holding parts being movable independently of one another.

Furthermore, the holding parts can be arranged on the container without touching one another.

The rubbish bag can be held firmly in the container with several holding parts. If the holding parts are not mechanically linked to one another and the holding structure parts move independently of one another, the holding parts can be designed in a structurally simple manner and can be arranged in the container in an uncomplicated manner.

• schräg zu allen Seitenwänden des Behälters, oder
• in sämtliche Richtungen, welche mit einem Winkel von grösser 5°, insbesondere grösser 15°, insbesondere grösser 30° zu sämtlichen Seitenwänden des Behälters verlaufen, oder
• in Richtung der Diagonalen des Behälters, oder
• in Richtung der Winkelhalbierenden der Behälterecke.

In a particular embodiment, the holding structure part is movable

• oblique to all side walls of the container, or
• in all directions which extend at an angle of greater than 5°, in particular greater than 15°, in particular greater than 30°, to all side walls of the container, or
• in the direction of the diagonals of the container, or
• in the direction of the bisector of the container corner.

The term "oblique" is defined as "non-parallel".

The understanding of the direction of movement of the holding structure part is made even clearer with reference to the figures.

The holding part advantageously has a spring element which is arranged between the holding structure part and the mounting part, in particular the spring element being a compression spring. The assembly part and the holding structure part can be brought into a defined position in the unstressed state by means of the spring element.

A solution with an elastically deformable holding structure part would also be conceivable, so that the spring element can be dispensed with.

The holding part advantageously consists of the holding structure part, the mounting part and the spring element. This means that the holding part includes precisely these three components. This construction is therefore a very simple and cost-effective design of the holding part.

Furthermore, the at least one holding part can be designed in such a way that it only extends within a container corner radius of at most 7 cm, in particular at most 5 cm. This space-saving configuration requires relatively little space in the container, so that the interior of the container can be used as completely as possible by the rubbish bag.

In a particular embodiment, the container corner spans an inner corner angle and the at least one holding part is designed symmetrically, with the bisecting line of the inner corner angle of the container forming the line of symmetry. What is to be understood by the bisecting line of the corner inner angle will be explained in more detail with reference to the figures. The symmetrical design enables the holding part to be placed in any corner of the container, which facilitates assembly of the device.

In particular, the at least one holding part can be removed from the container. Furthermore, the at least one holding part can have a clip part, which can be clipped into a recess arranged in the upper edge area of the container in order to mount the holding part on the container.

Advantageously, the clamping device has at least one further holding part, which in the middle area, in particular in the middle, between two container corners, in particular in the upper edge region of the side wall of the container, and is in particular configured identically to the at least one holding part arranged in the corner of the container.

An arrangement of the holding part in the central area also makes it possible to clamp garbage bags that are significantly smaller than the container. Furthermore, it can also be provided that several rubbish bags can be clamped into the same container.

The at least one further holding part and the at least one holding part are preferably configured identically. In particular, this makes it possible for the holding part to be arranged both at the container corner and in the central area. If, for example, four holding parts are present, all four holding parts can be arranged at the corners of the container in the case of a large garbage bag filling the container. If a much smaller garbage bag is to be clamped, two holding parts can be arranged at two adjacent corners of the container and two holding parts in the middle area.

"Arranged in the middle area" means that the holding part is not arranged in the corners of the container and its arrangement also does not partially overlap with the corner of the container. "In the middle area" means in particular in the middle 80%, in particular in the middle 50%, in particular in the middle 20% along the entire side wall of a container.

Advantageously, the container has four container corners and one of the at least one holding part is arranged in two or four container corners.

In particular, one of the at least one holding part has precisely one holding structure part.

Ways to carry out the invention

The embodiment shown in the figures has a container 1 with a substantially square cross section. The container 1 has four substantially vertical or slightly sloping side walls which form the top edges 1a, 1b, 1c, 1d of the container at their upper ends ( 2 ). The upper edges 1a, 1b, 1c, 1d are essentially straight and perpendicular to one another, so that an upwardly directed opening with an essentially rectangular, preferably square, cross-section is formed between them.

In 2 a total of four holding parts 3 are arranged on the upper edge region 2 of the container 1 at the four corners of the container, which are provided with a cover frame 4 ( 1 ) can be covered. The holding parts 3 are part of a clamping device with which a rubbish bag (not shown) can be clamped inside the container 5 . Since the holding parts 3 are arranged in the corners of the container and are designed to be relatively small in relation to the entire container 5, the refuse sack can be removed extremely easily from the container 5, even when it is full of refuse.

At the upper edge area 2 of the container 5 or in the present exemplary embodiment at the upper edges 1a, 1b, 1c, 1d there are recesses 6a and 6b, into which the holding parts 3 can be clipped with a clip part. The container 5 shown comprises recesses 6a, which are arranged at the container corners, and recesses 6b, which are arranged in the middle region between container corners on the side walls.

while in the 2 all four holding parts 3 are arranged at the corners of the container in order to open up a single garbage bag that fills the entire container, are in 3 only two of four holding parts 3 are arranged at the corners of the container and the other two holding parts 3 are arranged in the central region, so that a garbage bag that fills half of the container 5 can be stretched open. In 4 A total of eight holding parts 3 are mounted, so that in one container 5 two garbage bags of the same size, each filling half of the container 5, can be stretched. All in the Figures 2, 3 and 4 holding parts 3 shown are configured identically. Each of the holding parts 3 can be arranged either at a corner of the container or in the middle of the side walls. In other words, the holding parts 3 can be arranged wherever there are recesses 6a or 6b.

In the figure 5 a second embodiment is shown in which the container 5 is not square but rectangular.

6 shows an exploded view of the holding part 3. The holding part 3 comprises a mounting part 7 for fixing the holding part to the container 5, a holding structure part 8 for receiving the rubbish bag and a spring element 9. Both the mounting part 7 and the holding structure part 8 are involved in the present embodiment about injection molded parts.

The assembly part 7 has clip parts 7a with which the holding part 3 can be clipped into the recesses 6a and 6b arranged in the upper edge region 2 of the container 5 . Furthermore, the mounting part 7 has a recess 7b through which the holding structure part 8 can be moved.

The holding structure part 8 has a hook-shaped holding structure 8a on which the rubbish bag can be accommodated. The rubbish bag is wrapped around the bent end 8b so that it is reliably held on the holding structure part 8 . Furthermore, the holding structure part 8 comprises a spring receptacle 8c for the spring element 9 and rotary axis elements 8d in order to arrange the holding structure part rotatably on the mounting part 7 . The spring element 8 defines the relative position of the mounting part 7 and the support structure part 8 with respect to the rotational movement. It is a compression spring.

In the Figures 7 to 12 an assembled holding part 3 is shown. In the Figures 7 to 9 is the holding part 3 in the first position in which the garbage bag is easy to mount and the spring element 9 is compressed. In the Figures 10 to 12 the holding part 3 is in the second position in which the holding structure part 8 and the mounting part 7 are pressed apart by the spring element 9 and the mounted garbage bag is stretched. Positions that lie between the two extreme positions shown in the figures are also possible as mounting or clamping positions.

If the holding parts 3 are arranged in the container corners, the holding structure parts 8 span a smaller circumference in the first position than in the second position, because in the first position the holding structure parts 8 are further away from the container corners and are moved inwards.

If a user wants to stretch the garbage sack in the container, he mounts the garbage sack around three of the four holding structure parts 8 in a first step. To mount the garbage sack on the fourth holding structure part 8, the user pulls on the garbage sack so that the three holding structure parts 8, which the rubbish bag is already assembled, move into the interior of the container, or he manually pushes the fourth support structure part 8 into the first position, thereby doing so compresses the compression spring 9 in order to reduce the circumference defined by the four holding structure parts 8, so that the rubbish bag can also be easily mounted on the fourth holding structure part 8. As soon as the rubbish sack is also mounted on the fourth holding structure part 8, the user lets go of the device so that all holding structure parts 8 move outwards into the second position due to the spring force of the compression spring 9, so that the rubbish sack is stretched and when waste is filled into the rubbish sack is reliably held on the holding parts 3.

The support structure parts 8 are relative to the mounting parts along the arrow 10 ( 10 ) movable back and forth. The rotary axis elements 8d ( 6 , 9, 12 ) of the holding structure part 8, which are accommodated by openings 7c of the mounting part 7. The pivot elements 8d are rotatably mounted in the openings 7c.

The position between the holding structure part 8 and the mounting part 7 is defined by the spring element 9 . The spring element 9, which is a compression spring in the present case, is held by the spring receptacle 8c ( 6 and 12 ) from the holding structure part 8 and from a projection 7d ( 12 ) of the assembly part 7 was added and guided. The sectional view of 9 FIG. 12 shows the holding part 3 in the first position, in which the spring element 9 is compressed, and the sectional view 12 illustrates the holding part 3 in the second position, in which the spring element 9 is relaxed. The spring element 9 pushes the assembly part 7 and the holding structure part 8 apart.

• Die Winkelhalbierende 11a halbiert den 90°-Winkel der Behälterecke in zwei 45° Winkel. Der Winkel wird durch die Oberkanten 1a und 1b gebildet.
• Die Behälterdiagonale 11b verbindet die Behälterecken von links oben und rechts unten. Eine Bewegung des Haltestrukturteils 8 entlang der Behälterdiagonalen 11b entspricht einer Bewegung in Diagonalrichtung.
• Die Behälterecke rechts oben ist in drei 30°-Winkel 11c, 11d und 11e unterteilt. Gerade Linien, welche vom Anfangspunkt des Winkels ausgehen und im mittleren 30°-Winkelbereich 11e liegen stehen in einem Winkel von grösser 30° zu sämtlichen Seitenwänden des Behälters mit den Oberkanten 1a bis 1d.

the 13 shows a device with a container 5 viewed from above in a schematic representation. The upper edges 1a, 1b, 1c and 1d of the container 5 are visible 13 different terms are explained.

• The angle bisector 11a bisects the 90° angle of the container corner into two 45° angles. The angle is formed by the top edges 1a and 1b.
• The container diagonal 11b connects the container corners from the top left and bottom right. A movement of the holding structure part 8 along the container diagonals 11b corresponds to a movement in the diagonal direction.
• The container corner at the top right is divided into three 30° angles 11c, 11d and 11e. Straight lines which start from the starting point of the angle and lie in the central 30° angle range 11e are at an angle of greater than 30° to all side walls of the container with the upper edges 1a to 1d.

The arrow 11f represents a container corner radius of 10 cm, for example. The holding part 3 is thus located within the container corner radius of at most 10 cm.

The double file 11g extends over the middle 50% of the entire side wall with the upper edge 1c.
