Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority of German patent application no. 10 2023 107 396.6, filed Mar. 23, 2023, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to a collection bag for receiving a collected material. The collection bag is provided for use with a suction device for suctioning up a collected material such as leaves, dirt or the like. The collection bag is formed from a woven cloth which forms an internal receiving space which is defined by the outer edges of the collection bag. The woven cloth is at least partially air-permeable so that the blower air flow, which flows into the receiving space with the collected material, can flow out. The collection bag has an inlet opening for the entry of the blower air flow with the collected material. The collection bag has an outlet opening for at least partially diverting the blower air flow into the surroundings. The collected material which is collected in the collection bag is emptied via a closable emptying opening via an outlet opening of the collection bag.

BACKGROUND

The receiving of the collected material is dependent, amongst other things, on the degree of dryness thereof. Dry leaves can be easily suctioned up and emptied out, while wet leaves can only be received with difficulty and emptied out with difficulty. The storage of the collected material in the receiving space is also highly dependent on the degree of moisture of the collected material. Wet collected material accumulates in the collection bag, whereby in the case of wet leaves an effective emptying of the collection bag is frequently impeded.

Moreover, the emptying opening can be configured such that, while an inadvertent opening is reliably avoided during the operation of the suction device, a simple opening is still possible for the required emptying of the collection bag.

SUMMARY

It is an object of the disclosure to provide a collection bag for a suction device such that the emptying opening can be reliably closed but, on the other hand, a simple opening of the emptying opening is ensured so that wet and dry collected material received in the collection bag can be emptied in a simple and effective manner.

The object is, for example, achieved by the receiving space of the collection bag opening into an outlet section, the open end thereof forming the emptying opening. In a closed position, the outlet section securely closes the receiving space, in particular the emptying opening. In an open position, the outlet section connects the receiving space to the surroundings so that the collection bag can be emptied in a simple and effective manner, in particular via the emptying opening. In its open position, the outlet section protrudes from the collection bag and in its closed position the outlet section is located inside the collection bag. A secure closure of the emptying opening is provided by the position inside the collection bag. An inadvertent opening of the emptying opening during operation is avoided.

In the closed position of the outlet section, when the opening edge defining the emptying opening is folded at least once into the collection bag, this contributes to a secure closure of the emptying opening. A securing of the closed position of the outlet section is provided by the position inside the collection bag.

Expediently, the folded-in opening edge is secured in its folded-in closed position by the outer woven cloth of the collection bag. In the closed position of the outlet section, the emptying opening is thus located inside the collection bag and closes the receiving space for the collected material. The, in particular outer, woven cloth of the collection bag serves as a securing element for the closed position of the outlet section. The collection bag is closed according to the principle of a labyrinth seal.

In a development of the disclosure, the closed position of the outlet section which is folded into the woven cloth of the collection bag is secured by at least one closure element which is, in particular, held on the woven cloth of the collection bag. The closure element which is provided, in particular, on the outer face of the collection bag is easily accessible by the user, which facilitates the opening of the emptying opening.

In particular, the closure element is a buckle which is held on the outer face of the woven cloth of the collection bag.

For mechanical stabilization, the opening edge of the outlet section defining the emptying opening is reinforced by a flat bar. Preferably, it is provided to divide the flat bar in its longitudinal direction into at least two segments which are separate from one another.

Advantageously, a flap of the collection bag is reinforced by a flat bar, wherein the flat bar is divided in its longitudinal direction into at least two segments which are separate from one another.

In particular, it is provided that the fold of the opening edge which is formed in the closed position of the outlet section corresponds at least to the width of the flat bar. As a result, it is possible to achieve a mechanical stabilization of the opening edge of the emptying opening.

DETAILED DESCRIPTION

The schematic view in FIG. 1 shows a collection bag 1 in a side view. The collection bag 1 has an air-permeable wall, at least in partial regions. In particular, the collection bag 1 is made of an air-permeable woven cloth 2. A perforated canvas, a braided mesh or similar air-permeable wall is also understood as the woven cloth. The collection bag 1 has a rectangular basic shape. The narrow sides of the rectangular basic shape form a first edge 12 and a second edge 14 which oppose one another with a spacing. The first edge 12 and the opposing second edge 14 are connected together via longitudinal edges 11 and 13. The longitudinal edges 11 and 13 form at the same time the longitudinal edges of the rectangular basic shape of the collection bag 1. The edges 12 and 14 and the longitudinal edges 11 and 13 define a receiving space 5 located in the collection bag 1.

An attachment loop 19 can be provided at the upper longitudinal edge 11 of the collection bag 1. The attachment loop 19 can be configured for fastening a carrying belt, a strap or similar element.

The inlet opening 3 for a blower air flow 6 is configured on the first edge 12 of the collection bag 1. The blowing tube of a suction device, not shown in more detail, is connected to the inlet opening 3. As FIG. 1 shows, the inlet opening 3 is provided in the vicinity of the upper longitudinal edge 11 of the collection bag 1. In the embodiment shown, the inlet opening 3 is located in the corner between the upper longitudinal edge 11 and the first edge 12 of the collection bag 1.

An outlet opening 4 is configured in the second edge 14 of the collection bag 1 opposing the inlet opening 3. As FIG. 2 shows, the outlet opening 4 extends over the entire height C of the second edge 14. It can also be derived from FIG. 1 that the height A of the first edge 12 is smaller than the height C of the second edge 14. Starting from the first edge 12, the collection bag 1 widens in the direction of the second edge 14 with the outlet opening 4.

Advantageously a discharge opening 10 is provided in the side wall 7 of the collection bag 1. The discharge opening 10 is located between the outlet opening 4 and the inlet opening 3. The discharge opening 10 has a size which corresponds to approximately 10% to 20% of the total surface area of the side wall 7 of the collection bag 1. The discharge opening 10 serves for the at least partial diversion of the blower air flow 6 into partial flows 8. The diversion of the partial flows 8 of the blower air flow 6 through the discharge opening 10 is indicated by arrows in FIG. 1.

As FIG. 3 shows, the end of an advantageously tubular outlet section 20 protrudes from the outlet opening 4 of the collection bag 1. The receiving space 5 which is formed by the, in particular, air-permeable woven cloth 2 transitions into the outlet section 20. In particular, the receiving space 5 of the collection bag 1 opens into the outlet section 20 in the region of the outlet opening 4. The open end 21 of the outlet section 20 forms an emptying opening 9 for the receiving space 5 of the collection bag 1. A collected material received in the receiving space 5 of the collection bag 1 is emptied via the outlet section 20 and the emptying opening 9 of the outlet section 20. In the open position of the outlet section 20, shown in FIG. 3, the receiving space 5 of the collection bag 1 is connected to the surroundings. In this open position, the outlet section 20 protrudes from the collection bag 1.

The opening edge 15 of the outlet section 20 defining the emptying opening 9 is preferably reinforced by a flat bar 16. In one particular embodiment, the flat bar 16 is divided in its longitudinal direction 17, as is revealed in particular in FIG. 3. In the opening edge 15 of the emptying opening 9 the flat bar 16 is divided into at least two segments which are separate from one another. In the embodiment shown according to FIGS. 3 and 4, the flat bar 16 includes three segments 16.1, 16.2 and 16.3. The opening edge 15 according to FIG. 3 includes of two partial sections 15.1 and 15.2 which bear against one another in the closed position. A partial section 15.1 or 15.2 has in each case a flat bar 16 which is divided into at least two segments. Therefore, a total of six segments are configured in the opening edge 15 according to FIG. 3. The open position of the emptying opening 9 can be stabilized by the division of the flat bar 16 into segments.

It can be advantageous to reinforce the flap 30 of the collection bag 1 by a flat bar 26, as is shown for example in FIG. 1. The flat bar 26 of the flap 30 can be divided in its longitudinal direction 27 into at least two segments 26.1, 26.2 which are separate from one another.

The outlet section 20 is configured in a closed position to close the receiving space 5, in particular the emptying opening 9. The outlet section 20 is also configured in an open position to connect the receiving space 5 to the surroundings. The arrangement is configured such that in its open position the outlet section 20 protrudes from the collection bag 1 and in its closed position the outlet section is located inside the collection bag 1.

For closing the emptying opening 9 or for closing the open end 21 of the outlet section 20, the opening edge 15 is folded in at least once in the direction of the arrow 44, as shown in FIG. 5. At least a first fold 22 is formed in the closed position of the outlet section 20 according to FIG. 5. The fold 22 of the opening edge 15, which is formed in the closed position of the outlet section 20, has a width B which corresponds at least to the width F of the flat bar 16. In the closed position of the outlet section 20, the opening edge 15 defining the emptying opening 9 is folded at least once into the collection bag 1. Preferably, it is provided to fold in the opening edge 15 twice so that a double fold 22 is formed in the closed position of the outlet section 20.

As FIG. 1 and, in particular, FIG. 6 show, the outlet section 20 is located inside the collection bag 1 in a closed position of the emptying opening 9. The opening edge 15 which is folded into the collection bag 1 is located outside the receiving space 5. The opening edge 15 which is folded into the collection bag 1 is located inside the collection bag 1 formed by the woven cloth 2. The folded-in opening edge 15 is secured in its folded-in closed position by the outer woven cloth 2 of the collection bag 1. Advantageously, a flap 30, which is shown raised in FIGS. 3 and 4, is provided on the outlet opening 4 of the collection bag 1. The flap 30 is folded back around the outlet opening 4 so that the outlet opening 4 of the collection bag 1 is closed by the flap 30. The outlet section 20 is located, in particular, entirely below a flap 30 of the collection bag 1. The collection bag 1 is closed according to the principle of a labyrinth seal. The closure element 40 is, in particular, a buckle which is held on the outer face of the woven cloth 2 of the collection bag.

The closed position of the flap 30 is secured by at least one closure element 40. The closed opening edge 15 of the emptying opening 9 of the outlet section 20, which is located in the collection bag 1, is fixed in its closed position by the flap 30 which is held by the closure element 40 in the closed position. Expediently, a plurality of, in particular three or four, closure elements 40 are provided over the height C of the outlet opening 4.

In order to empty the collection bag 1, only the closed closure elements 40 have to be opened up and the flap 30 folded back. If the collection bag 1 is held with its outlet opening 4 facing the floor, after the flap 30 is opened the collected material will enter the outlet section 20 and—since the closed position of the emptying opening 9 of the outlet section 20 is no longer secured—the folded-in emptying opening 9 will be opened. The user can assist this by manually opening the folded-in opening edge 15.

It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
