Collecting unit for bird feces, blank for such a collecting unit, pre-product for a plurality of collecting units and pre-product for a plurality of blanks

Abstract

According to the invention, a collecting unit has been created which consists of at least one collecting part, at least one supporting structure, and at least one holding device for holding on an object. Since a device for preventing a bird from perching on the at least one collecting part and / or the at least one supporting structure or a combination structure composed of the at least one collecting part and the at least one supporting structure is also provided, the bird is prevented from sitting on the at least one collecting part or the at least one supporting structure and dropping feces from there. If the bird sits on the object in the region of the collecting unit, the feces are reliably collected by the collecting unit, whereas if the bird wants to perch on the at least one collecting part and / or the at least one supporting structure, collection is prevented, and therefore the lingering of the bird on these components and the resulting possibility of such defecation by the bird is reliably prevented.

Description

[0001] Bird droppings collection unit, cut-out for such a collection unit, semi-finished product for a large number of collection units and semi-finished product for a large number of cut-outs

[0002] Bird owners, in most cases, allow their birds not only to remain in their cages but also to roam freely in the indoor areas of an apartment or house. However, this often leads to the problem that the birds defecate uncontrollably indoors.

[0003] To solve the problem, US 4,660,507 A proposes attaching a perch for a bird to a window pane using suction cups, with a tray attached to the perch which, when the bird is perched on the perch, serves to collect its droppings.

[0004] DE 296 22 177 Ul discloses a support structure for a perch, which has a holder in an area spaced away from the perch, into which paper can be inserted to collect bird droppings. The support structure can be mounted on a smooth surface, such as a mirror, by means of suction hooks. Even with this prior art, bird droppings are only collected when the bird is perched on the perch.

[0005] However, state-of-the-art bird droppings collection devices have a very limited range of application, as they can only be attached to objects where suction cups or suction hooks can be used. Furthermore, there is the problem that the birds do not perch on the intended perch, but instead perch on the droppings collection devices and defecate from there, past the collection device.

[0006] The invention is therefore based on the objective of creating a versatile collection unit for the effective collection of bird droppings, as well as a design for such a collection unit.

[0007] This problem is solved by the features specified in claims 1 and 8. According to the invention, a collection unit has been created comprising at least one collection part, at least one support structure, and at least one holding device for attaching it to an object. Furthermore, by providing a device to prevent a bird from perching on the at least one collection part and / or the at least one support structure or a combination thereof, it is prevented that the bird perches on the at least one collection part or the at least one support structure and defecates from there.Therefore, if the bird lands on the object within the area of ​​the collection unit, the droppings are safely collected by the collection unit; however, if the bird attempts to land on at least one collection part and / or at least one supporting structure, this is prevented, thus reliably preventing the bird from remaining on these components and thereby preventing the bird from depositing droppings.

[0008] Another advantage of the collection unit according to the invention is its simple design and inexpensive manufacture.

[0009] In a particularly advantageous way, only mechanical parts are used for the collection unit, while the inclusion of electronic assemblies was deliberately omitted for reasons of sustainability.

[0010] A particular advantage of the capture unit is that the device designed to prevent the bird from being injured effectively prevents injury.

[0011] Preferably, the device for preventing a bird from landing is designed in such a way that the collecting element, or at least a part thereof, and / or the supporting structure, or at least a part thereof, are deformable and / or movable. This effectively prevents a bird from landing on any part of the collecting unit without the need for potentially harmful devices such as spikes.

[0012] The movement of a part of the collection unit to prevent a bird from landing is a translational movement, a rotational movement, or a combination thereof. According to a preferred embodiment, the collection unit is elongated along a longitudinal direction or formed along a curved contour. This provides a large area for collecting the droppings.

[0013] In one advantageous embodiment, the collection unit is designed as a tubular structure made of a material that exhibits both rigid and flexible properties, thus enabling the structure to perform highly dependent on the load, particularly on bird droppings or the bird's landing. The tubular structure can be cut from a continuous strand of material and is therefore easy to manufacture. Since this largely eliminates waste, this solution is particularly resource-efficient.

[0014] In another advantageous embodiment, the tubular structure is created by folding and joining a flat material. This allows for the production of various types of collection units that have a tubular structure.

[0015] Furthermore, the advantage of the collection unit according to the invention is that the collection of droppings can take place not only at a specific location, e.g. a specially created perch with an associated droppings collection device, but that places where birds like to perch, such as on the top edges of doors, monitors, cabinets and shelves, can be equipped with the collection unit according to the invention.

[0016] In embodiments of the collection unit according to the invention that consist entirely of paper or cardboard, the advantage lies in the possibility of environmentally sustainable disposal after use.

[0100] Figures 1A and 1B show, according to a first embodiment, a collecting unit Al comprising a tubular structure 10 consisting of a base section 12, a collecting section 14, and a strut section 16. The collecting section 14 extends from a first (upper) end 12.1 of the base section 12 away from the base section 12, the first end 12.1 of the base section coinciding with a first end 14.1 of the collecting section 14. The strut section 16 extends from a second end 14.2 of the collecting section 14, located furthest from the base section 12, to a second (lower) end 12.2 of the base section 12.

[0101] The tubular structure 10 has the shape of a triangle in side view and, together with the base section 12, the catch section 14 and the strut section 16, defines a cavity 18. The tubular structure 10 is elongated along a longitudinal direction LR with a length L, along a lateral direction BR with a width B and along a vertical direction HR with a height H.

[0102] A mounting adhesive surface 20 is provided on the base section 12. In the embodiment shown, this extends over the entire length L of the base section 12 and extends from the first end 12.1 towards the second end 12.2 over a predetermined distance.

[0103] The mounting adhesive surface 20 serves to mount or hold the collection unit Al to an object in the form of a door T, as shown in Fig. IC. The width B of the collection section 14 (Fig. 1 A) is dimensioned such that the droppings of a bird V sitting on the top of the door T can be collected by the collection section 14 and is at least as large as the distance between the claws K (Fig. 13) and a cloaca of the respective bird V.

[0104] Preferably, when determining the width B of the collection section 14, it is taken into account that the bird V may also defecate when taking off.

[0105] Figures 2A and 2B show a second embodiment of a collection unit A2, which is largely identical to collection unit Al and has a tubular structure 10a consisting of a base section 12, a collection section 14a, and a strut section 16. The collection section 14a has two sections 14al and 14a2, which are inclined towards the cavity 18. This forms a channel 15, which further optimizes the collection of bird V's droppings.

[0106] In the embodiment shown, the channel 15 is V-shaped. In other modifications, the channel 15 has a different shape, for example, a rounded shape. Fig. 2C shows the collection unit A2, which is attached to the door T by means of the mounting adhesive surface 20.

[0107] The tubular structure 10, 10a is designed such that, when subjected to a load below a first threshold value, the collecting section 14, 14a retains its shape in such a way that its collecting function is maintained. However, when subjected to a load above a second threshold value, the collecting section 14, 14a is designed to be flexible, such that under load the collecting section 14, 14a moves towards the base section 12 and the cavity 18 is compressed, thus preventing the bird V from landing. The first threshold value is determined by the weight of the collected droppings, while the second threshold value is determined by the weight of the bird V.

[0108] In the first and second embodiments, the collecting element is represented by the collecting section 14, 14a, the supporting structure by the base section 12, the collecting section 14, 14a (which has a dual function as a collecting element and part of the supporting structure), and the strut section 16. The mounting adhesive surface 20 corresponds to the holding device, and the device for preventing a bird from landing is represented by the flexibility of the collecting section 14; 14a.

[0109] The tubular structure 10, 10a can be separated from a tubular strand of material, so that the respective tubular structure 10, 10a with a length L, which depends on the type of object and its application, is obtained. Thus, the tubular structure 10, 10a is easy to manufacture.

[0110] Fig. 3A shows a surface structure Fl, which is provided as a blank for a collection unit A3 according to a third embodiment, as shown in Figs. 3B and 3C. The surface structure Fl has an upper side S1 and a lower side S2 opposite it. The surface structure Fl has a base section 32, a collection section 34, a strut section 36 and a connecting section 40.

[0111] The sheet structure Fl consists of a foldable, flexible material, such as paper, thicker film, or a reinforced fabric. A first fold line FL1 is provided between the connecting section 40 and the collection section 34, a second fold line FL2 between the collection section 34 and the strut section 36, and a third fold line FL3 between the strut section 36 and the base section 32. The first, second, and third fold lines FL1, FL2, and FL3 are designed for folding in a first fold direction that points towards the lower side S2 of the sheet structure Fl, in order to form the collection unit A3 with a tubular structure 30.

[0112] The base section 32 has the mounting adhesive surface 20, which is designed for mounting or holding the collection unit A3 on an object in the form of a door T, analogous to the embodiment shown in Fig. 1C.

[0113] Folding the sheet structure Fl along the fold lines FL1, FL2, FL3, as described above, results in the support unit A3 with the tubular structure 30, as shown in Fig. 3B. In this embodiment, one end 32.1 of the base section 32 coincides with the first fold line FL1. The connecting section 40 is equipped with an adhesive bonding surface 42, which ensures a firm connection between the connecting section 40 and the base section 32. In this embodiment, the adhesive bonding surface 42 extends over the entire connecting section 40 in the longitudinal direction LR.

[0114] The tubular structure 30, as shown in Fig. 3B, has the shape of a triangle in the side view and, together with the base section 32, the catch section 34 and the strut section 36, defines a cavity 38.

[0115] As shown in Fig. 3C, the tubular structure 30 has a length L in the longitudinal direction LR, with the collecting section 34 having a width B analogous to the width B of the collecting section 14 of Fig. 1, as can be seen from Fig. 3B.

[0116] Fig. 4A shows a sheet F2, which is provided as a blank for a collection unit A4 according to a fourth embodiment, as shown in Fig. 4B. The sheet F2 is largely identical to the sheet Fl, except that a groove fold line FLR is provided between the first fold line FL1 and the second fold line FL2, so that a collection section 34a is divided into two sections 34al and 34a2. By folding the sheet F2, the collection unit A4 is formed with a tubular structure 30a, which is shown in Figs. 4B and 4C, similar to the tubular structure 30 of Fig. 3B, wherein the two sections 34al and 34a2 are inclined towards the cavity 38. This forms a channel 35, which further optimizes the collection of bird V's droppings.

[0117] In this embodiment, the lowest point of the channel 35 is lower in the vertical direction HR than the end of the collection section 34a furthest from the base section 32, which corresponds to the fold line FL2.

[0118] In the version shown, the channel 35 is V-shaped. In other modifications, the channel 35 has a different shape.

[0119] Fig. 4D shows the collection unit A4, which is attached to the door T by means of the mounting adhesive surface 20.

[0120] It should be noted that the collection unit A3 is attached to door T corresponding to the collection unit A4 at door T.

[0121] The collection units A3 and A4 have the advantage of a simple design and that the mounting adhesive surface 20 and the connecting adhesive surface 42 are located on the same side of the surface structure F1, F2.

[0122] Alternatively, in a modified embodiment, the connecting section 40 is connected to the strut section 36 and overlaps the base section 32 in its lower area.

[0123] Fig. 5A shows a sheet-like structure F3, which is provided as a blank for a collection unit A5 according to a fifth embodiment, as shown in Figs. 5B and 5C. The sheet-like structure F3 has an upper side S1 and a lower side S2 and comprises a base section 32A, the collection section 34, the strut section 36, and the connecting section 40. Folding the fold lines FL1, FL2, and FL3 results in the collection unit A5 with a tubular structure 30b, as shown in Figs. 5B and 5C. In this embodiment, the first fold line FL1 is designed for folding in a second folding direction, pointing towards the upper side S1 of the sheet-like structure F3, and the second and third fold lines FL2 and FL3 are designed for folding in the first folding direction, pointing towards the lower side S2 of the sheet-like structure F3.

[0124] In this embodiment, the bonding surface 42 is arranged on the lower side S2 of the connecting section 40. As shown in Fig. 5B, in this embodiment the bonding surface 42 also functions as the mounting surface. This is achieved by the fact that the base section 32A extends with its end 32Al beyond the area of ​​the first fold line FL1 in the vertical direction HR, but does not occupy the entire dimension of the connecting section 40 in the vertical direction HR.

[0125] Fig. 6A shows a surface structure F4, which is provided as a blank for a collection unit A6 according to a sixth embodiment, as shown in Fig. 6B. The surface structure F4 is largely identical to the surface structure F3, except that a collection section 34a is divided into two sections 34al, 34a2 by the channel fold line FLR.

[0126] Figures 6B and 6C show the collection unit A6 with a tubular structure 30c, which is essentially identical to the tubular structure 30b, wherein the two sections 34al and 34a2 are inclined towards the cavity 38. This forms the trough 35, which further optimizes the collection of bird V's droppings.

[0127] Fig. 6D shows the collection unit A6, which is installed at door T.

[0128] It should be noted that the collection unit A5 is attached to door T corresponding to the collection unit A6 at door T.

[0129] The collection units A5 and A6 have the advantage of a simple design and that the connecting adhesive surface 42 simultaneously serves as the mounting adhesive surface, so that only one adhesive surface is required.

[0130] Fig. 7A shows a sheet element F5, which is provided as a blank for a collection unit A7 according to a seventh embodiment, as shown in Figs. 7B and 7C. The sheet element F5 has the upper side S1 and the lower side S2 and has a base section 32B, the collection section 34, the strut section 36 and a connecting section 40A. Folding the fold lines FL1, FL2 and FL3 results in the collection unit A7 with a tubular structure 30d, as shown in Figs. 7B and 7C.

[0131] In this embodiment, the first fold line FL1 is designed for folding in a second folding direction, which points towards the upper side S1 of the surface structure F5, and the second and third fold lines FL2, FL3 are designed for folding in the first folding direction, which points towards the lower side S2 of the surface structure F5.

[0132] In this embodiment, the bonding surface 42 is located on the lower side S2 of the base section 32B. The mounting surface 20 is located on the lower side S2 of the connecting section 40A. As shown in Fig. 7B, which depicts the collection unit A7 with the tubular structure 30d, one end 32B1 of the base section 32B is positioned so far from the first fold line FL1 that the entire bonding surface 42 lies above the first fold line FL1 in the vertical direction HR.

[0133] The connecting section 40A has a dimension in the vertical direction HR such that the mounting adhesive surface 20 and the connecting adhesive surface 42 fit completely within this space. Preferably, as shown in Fig. 7B, a vertical distance h between an end 32B1 of the base section 32B and between an end 40A1 of the connecting section 40A is dimensioned such that a distance a exists between the connecting adhesive surface 42 and the mounting adhesive surface 20.

[0134] Fig. 8A shows a surface structure F6, which is provided as a blank for a collection unit A8 according to an eighth embodiment, as shown in Figs. 8B and 8C. The surface structure F6 is largely identical to the surface structure F5, except that the collection section 34a is divided into two sections 34al, 34a2 by the channel fold line FLR.

[0135] Figures 8B and 8C show the collection unit A8 with a tubular structure 30e, which is essentially identical to the tubular structure 30d, wherein the two sections 34al and 34a2 are inclined towards the cavity 38. This forms the trough 35, which further optimizes the collection of bird V's droppings.

[0136] Fig. 8D shows the collection unit A8, which is installed at door T.

[0137] It should be noted that the collection unit A7 is attached to door T corresponding to the collection unit A8 at door T.

[0138] The collection units A7 and A8 have the advantage that a large area of ​​the door T above the tubular structure 30d and above the collection section 34a, respectively, is covered to prevent it from being soiled by bird droppings. Since birds generally tend to peck at anything within reach of their beaks, a further advantage is that the connecting section 40A is dimensioned such that the tubular structure 30d is out of reach of the beak of the respective bird V when the bird V is perched on the door T.

[0139] In alternative embodiments of the collection units A7 and A8, both the mounting adhesive surface 20 and the connecting adhesive surface are arranged on the connecting section 40A.

[0140] In further alternative embodiments of the collection units A7 and A8, the respective mounting adhesive surface 20 is arranged on the door itself or on a carrier that is attached to the door T and has the mounting adhesive surface 20.

[0141] Fig. 9A shows a sheet-like structure F7, which is provided as a blank for a collection unit A9 according to a ninth embodiment, as shown in Figs. 9B and 9C. The sheet-like structure F7 has the upper side S1 and the lower side S2 and includes the base section 32B, the collection section 34, the strut section 36, and a connecting section 40B. Folding along the fold lines FL1, FL2, and FL3 results in the collection unit A9 with a tubular structure 3Of, as shown in Fig. 9B.

[0142] In this embodiment, the first fold line Fl is designed for folding in the second folding direction, which points towards the upper side S1 of the surface structure F7, and the second and third fold lines FL2, FL3 are designed for folding in the first folding direction, which points towards the lower side S2 of the surface structure F7.

[0143] The bonding surface 42 is, as in the embodiments of the collection units A7 and A8, located on the lower side S2 of the base section 32B. In contrast to the embodiments of the collection units A7 and A8, no mounting bonding surface 20 is provided.

[0144] Instead, a U-shaped mounting bracket 50 is provided, as shown in Fig. 9D and 9E, which has the function of the holding device on the door T, as shown in Fig. 9E.

[0145] In the illustrated embodiment, the mounting bracket 50 is elongated and exerts a clamping effect between the upper end of the connecting section 40B and the door T. In a modified embodiment, the base section 40B is designed to lie over the top of the door T. In the latter embodiment, it is sufficient in some cases to provide a mounting rail without a clamping effect, whereby the friction between the base section 40B and the top of the door T or the mounting rail is sufficient to hold the collection unit A9 against the door T.

[0146] As shown in Fig. 9B, which shows the collection unit A9 with the tubular structure 30f, the end 32B1 of the base section 32B is formed from an end 40B1 with a height distance hl which is of the same order of magnitude as the height distance h of the embodiments of the collection units A7 and A8.

[0147] With this collection unit A9, as shown in Fig. 9E, a large area of ​​the door T is covered to prevent it from being soiled by bird droppings. As explained in connection with the collection unit A8, a further advantage is that the connecting section 40B is dimensioned such that the tubular structure 3 Of is outside the reach of the beak of the bird V when the bird V is perched on the door T. In addition, the mounting bracket 50 prevents the bird V from pecking at the upper edge of the connecting section 40B. Furthermore, the mounting bracket 50 protects the door T itself from damage by the claws K of the bird V.

[0148] Fig. 10A shows a surface structure F8, which is intended as a blank for a collection unit A10 according to a tenth embodiment, as shown in Fig. 10B and IOC. The surface structure F8 is largely identical to the surface structure F7, except that the collection section 34a is divided into two sections 34al, 34a2 by the channel fold line FLR.

[0149] Fig. 10B and IOC show the collection unit A10 with a tubular structure 30g, which is essentially identical to the tubular structure 30f, wherein the two sections 34al and 34a2 are inclined towards the cavity 38. This forms the trough 35, which further optimizes the collection of bird V's droppings.

[0150] Fig. 10D shows the collection unit A10, which is installed on the door T by means of the mounting bracket 50.

[0151] It should be noted that the collection unit A9 is attached to door T corresponding to the collection unit A10 at door T.

[0152] Like the A7 and A8 collection units, the A9 and A10 have the advantage of covering a large area of ​​the door T, thus preventing it from being soiled by bird droppings. Since the mounting bracket 50 is designed as a fastener for installation on the door T, the A9 and A10 collection units can also be attached to objects sensitive to adhesives.

[0153] In the third to tenth embodiments, the collecting element is represented by the collecting section 34, 34a, the supporting structure by the base section 32, 32A, 32B, the collecting section 34, 34a (which has a dual function as a collecting element and part of the supporting structure), and the strut section 36. The mounting adhesive surface 20 or the connecting adhesive surface 42, insofar as it fulfills the function of the mounting adhesive surface in one embodiment, and the mounting clamp 50 correspond to the holding device, and the device for preventing a bird from landing is represented by the flexibility of the collecting section 34, 34a.

[0154] Fig. 11A shows a flat structure F9, which is intended as a blank for a collection unit Al1 according to an eleventh embodiment, as shown in Figs. 11B and 11C. The flat structure F9 has the upper side S1 and the lower side S2 opposite it.

[0155] The surface structure F9 has a first connecting section 40Li, a second connecting section 40Re, a first receiving section 34aLi, a second receiving section 34aRe, a first strut section 36Li, a second strut section 36Re, and a base section 32G that connects the first strut section 36Li and the second strut section 36Re. The center of the base section 32G is represented by a center line M.

[0156] Between the first connecting section 40Li and the first catchment section 34aLi there is an associated first fold line FLILi, between the first catchment section 34aLi and the first strut section 36Li there is an associated second fold line FL2Li, between the first strut section 36Li and the base section 32G there is an associated third fold line FL3Li, between the second connecting section 40Re and the second catchment section 34aRe there is an associated first fold line FLIRe, between the second catchment section 34aRe and the second strut section 36Re there is an associated second fold line FL2Re and between the second strut section 36Re and the base section 32G there is an associated third fold line FL3Re.

[0157] Furthermore, the first collection section 34aLi is subdivided into two sections 34aLil and 34aLi2 by a groove fold line FLRLi and the second collection section 34aRe is subdivided into two sections 34aRel and 34aRe2 by a groove fold line FLRRe to form the respective channels 35Li, 35Re.

[0158] The first connecting section 40Li has a first bonding surface 42Li, and the second connecting section 40Re has a second bonding surface 42Re. A fixing adhesive surface 44 is provided on the overall base section 32G near the third fold line FL3Li.

[0159] The respective first, second, and third fold lines FLILi, FL2Li, FL3Li, FLIRe, FL2Re, FL3Re are designed for folding in the first fold direction, which points towards the lower side S2 of the surface structure Fl, in order to form the collection unit All l with two tubular structures 30hLi, 30hRe, each with a cavity 38Li, 38Re, as shown in Fig. 11B. In the region of the center line M, the base section 32G has a reversal section 32GU, thereby reversing the direction of the base section 32G in the region of the center line M.

[0160] Figure 11C shows a support rod 70 of a first embodiment, which has a rod 72 with curved hooks 74 at its ends. The rod 72 serves to hold the collection unit All in the area of ​​the reversing section 32GU.

[0161] Fig. 11D shows a rod 76 to which the curved hooks 74 of the support rod 70, which holds the collection unit All, are attached. Instead of the rod 76, the curved hooks 74 can also be attached to natural branches, as are predominantly found in aviaries.

[0162] In the eleventh embodiment, the collecting element is represented by the respective collecting section 34aLi, 34aRe, the supporting structure by the overall base section 32G without the reversing section GU, the respective collecting section 34aLi, 34aRe (which has a dual function as a collecting element and part of the supporting structure), and the respective strut section 36Li, 36Re. The reversing section 32GU and the fixing adhesive surface 44 function as the holding device, and the device for preventing the bird V from landing is represented by the compliance of the respective collecting section 34aLi, 34aRe.

[0163] Although not shown in detail, in a modified embodiment where the collection unit All is attached to a door T, the mounting clip 50 is used as an additional fixing element. In this embodiment, the fixing adhesive surface 44 can be omitted. The mounting clip 50 has a U-shape or is adapted to the profile of the top of the door T. The mounting clip 50 is prefabricated in one embodiment. In another embodiment, the mounting clip 50 is formed into the desired shape by bending, thermoplastic deformation, or chemical curing.

[0164] Fig. 12A shows a surface structure F10, which is intended as a blank for a collection unit A12 according to a twelfth embodiment, as shown in Figs. 12B and 12E. The surface structure F10 has the upper side S1 and the lower side S2 opposite it. The surface structure F10 has a base section 32C, the collection section 34a with two sections 34a1 and 34a2, the strut section 36, and the connecting section 40. The base section 32C is formed with the fixing adhesive surface 44, and the connecting section 42 is formed with the bonding adhesive surface 42.

[0165] The first, second and third fold lines FL1, FL2, FL3 are provided for folding in the first fold direction, which points towards the lower side S2 of the surface structure Fl, in order to form the collecting unit Al 2 with a tubular construct 30i, as shown in Fig. 12B.

[0166] The base section 32C has a height that extends beyond the first fold line FL1 and is equipped with a reversal section 32CU, thereby reversing the direction of the base section 32C. This makes it possible for a part of the base section 32C, which is equipped with the fixing adhesive surface 44, to be fixed to the opposite part of the base section 32C.

[0167] Fig. 12C shows a support rod 80 according to a second embodiment with a rod 82, at the ends of which rectangularly bent hooks 84 are arranged. The hooks 84 are shaped so that they can be attached to a suitable object, e.g., the door T. The rod 82 serves to hold the collection unit Al 2 in the area of ​​the reversing section 32CU.

[0168] Fig. 12D shows a support rod 90 according to a third embodiment with a rod 92, at the ends of which curved hooks 94 are arranged. At least the curved hooks 94 of the support rod 94 are designed to be plastically deformable, so that it can be adapted to the contour of an edge of an object to which the support rod 90 is to be attached.

[0169] In the twelfth embodiment, the collecting element is represented by the collecting section 34a, the supporting structure by the base section 32C without the reversing section CU, the collecting section 34a (which has a dual function as a collecting element and part of the supporting structure), and the respective strut section 36. The reversing section 32CU and the fixing adhesive surface 44 function as the holding device, and the device for preventing the bird V from landing is represented by the flexibility of the collecting section 34a.

[0170] Alternatively, in a modified embodiment, the fixing adhesive surface 44 is replaced by a mounting adhesive surface 20 in order to hang the collection unit Al 2 over an object and to attach it to the back of the object using the mounting adhesive surface 20.

[0171] As with the tubular structure 30, the tubular structures 30a to 30i have a triangular shape in side view and, together with the base section 32, 32B, 32C, 32G, the catch section 34, 34a, 34aRe, 34aLi and the strut section 36, 36Re, 36Li, define the cavity 38, 38Re, 38Li. The respective tubular structure 30a to 30i is elongated along the longitudinal direction LR.

[0172] The tubular structure 30, 30a to 30i is designed such that, when subjected to a load below a first threshold value on the collecting section 34, 34a, 34aRe, 34aLi, it retains its shape in such a way that a collecting function is maintained, but when subjected to a load above a second threshold value on the collecting section 34, 34a, 34aRe, 34aLi, it is designed to be flexible, such that under load the collecting section 34, 34a, 34aRe, 34aLi moves towards the base section 32, 32B, 32C, 32G and the cavity 38, 38Re, 38Li is compressed, thus preventing the bird V from landing. The first threshold is determined by the weight of the collected droppings, while the second threshold is determined by the weight of the bird V.

[0173] The statements regarding the length L in the longitudinal direction LR, the width B in the lateral direction BR and the height H in the vertical direction HR, which were made in connection with the third embodiment, apply equally to the fourth to twelfth embodiments.

[0174] It should be noted that in modified embodiments not shown, the folding direction of the fold lines Fl to F3 and the arrangement of the mounting adhesive surface 20 and the connecting adhesive surface 40 differ from the preceding embodiments. For example, unlike the embodiment of Fig. 3B, the connecting section 40 is provided for mounting on the door T, and the base section 32 is overlapped by the connecting section 40. As a further example, unlike the embodiment of Fig. 7B, the base section 32B is longer than the connecting section 40A. In this case, the mounting adhesive surface 20 is arranged on the base section 32B. It is generally known that birds like to try to perch on any kind of ledge or ledge. This also applies, for example, to the collection section 14, 34 or the respective section 14a2, 34a2, 34aLi2, 34aRe2 of the collection section 14a, 34a, 34aLi, 34aRe.

[0175] Fig. 13 shows, using a simplified representation of the eighth collection unit A8, the functioning of the corresponding collection units Al to A12 when the bird V attempts to land on the collection section 14, 34 or the respective section 14a2, 34a2 of the collection section 14, 34. According to the embodiment shown, the bird lands with its claws K on section 34a2 of the collection section 34. However, since both the entire collection section 34 and the strut section 16 are designed to be flexible, they deform, thus reducing the size of the cavity 38. In the exemplary embodiment with the groove 15, this deformation has the additional effect of reducing the distance between the head of the bird V and section 34a of the collection section 34a, thereby triggering a startling moment for the bird V.

[0176] Bird V cannot find a foothold and therefore slips off section 34a2 of the landing section 34. Since the bird is capable of learning, after a few more unsuccessful landing attempts it will refrain from landing on section 34a2 of the landing section, which applies analogously to landing units 14, 34 and section 14a2 of landing section 14.

[0177] As shown in Fig. 14, the embodiments with the channel 15, 35 have the advantage that by folding the collection section 14a, 34a, they can be folded in such a way that the strut section 16, 36 is pivoted towards the base section 12, 32, 32A, 32B, 32C, thus creating a flat product. This simplifies the storage, handling, and shipping of such collection units A2, A4, A6, A8, A10, A11, A2, A12, especially when the volume is small.

[0178] Like the sheet structures Fl and F2, the sheet structures F3 to Fl 0 preferably consist of paper, thicker foil or a reinforced fabric material.

[0179] The advantage of the collection units A3 to A12, which are manufactured from a sheet structure Fl to F10, is that a blank representing the respective sheet structures Fl to F10 can be marketed as a semi-finished product, which the buyer then assembles into the corresponding collection unit A1 to A12. In this case, the fold lines FL1 to FL3 and FLR can be designed with folding aids in the form of crease lines or perforations. Furthermore, the mounting adhesive surface 20, the connecting adhesive surface 42, 42Li, 42Re, and the fixing adhesive surface 44 are each provided with a protective strip on these blanks. Alternatively, the sheet structures Fl to Fl0 are designed like sticky note pads.

[0180] The mounting adhesive surface 20, the connecting adhesive surface 42, 42Li, 42Re and the fixing adhesive surface 44 preferably contain a non-toxic adhesive that can be removed without leaving any residue.

[0181] Preferably, at least the collection section 14, 14a, 34, 34a, 34aLi, 34aRe is made of an absorbent material. A material with porous properties has proven advantageous, as the droppings adhere to the collection section 14, 14a, 34, 34a, 34aLi, 34aRe even when dry, thus minimizing the risk of droppings falling off the collection section 14, 14a, 34, 34a, 34aLi, 34aRe when the bird V flies past, comes into contact with the bird V, or when the collection unit Al to A12 is replaced.

[0182] In test series, paper from A3 to Al2 proved to be particularly suitable as material for the collection units, with a basis weight between 40g / m². 2 and 80 g / m² 2and in particular a basis weight of 50g / m² 2 This is advantageous. The collection units should be replaced weekly, based on the recommendation of veterinarians to clean the cage weekly.

[0183] The respective adhesive surface 20,42, 42Li, 42Re, 44 is designed as a continuous adhesive track, as an interrupted adhesive track or as an adhesive surface in the form of adhesive dots.

[0184] In a modified embodiment not shown, the cavity 18, 38, 38Li, 38Re contains a foam which promotes a return to the original shape after loading of the collection unit Al to Al 1.

[0185] Fig. 15A shows a flat structure Fl 1, which is provided as a blank for a collecting unit Al 3 according to a thirteenth embodiment, as shown in Figs. 15J and 151 for curved objects. The flat structure Fl 1 has the upper side S1 and the lower side S2 opposite it.

[0186] The surface structure Fl 1 has a longitudinal fold line LFL along its length and a plurality of height fold lines HFL arranged at equal intervals in the height direction HR. The longitudinal fold line LFL divides the surface structure Fl 1 into a base section 102 and a catch section 104. At an end 102e of the base section 102, located away from the longitudinal fold line LFL, there is an adhesive surface 106 that extends over the entire length L in the longitudinal direction, but only over a portion in the height direction HR.

[0187] The base section 102 is subdivided into first sub-sections 102a by the longitudinal fold lines HFL and the receiving section 104 is subdivided into second sub-sections 104a by the longitudinal fold lines HFL.

[0188] An arrow PI in Fig. 15A shows how the collecting section 104 is folded in a first folding step around the longitudinal fold line LFL towards the lower side S2, so that a folded product is created as shown in Fig. 15B.

[0189] Starting from the folded product of Fig. 15B, folding is carried out alternately in the direction of the arrows P2 along the height fold lines HFL, as shown in Fig. 15C, so that a folded product as shown in Fig. 15D is created.

[0190] The folding process according to Fig. 15C creates alternating V-shaped pockets 102b and wedge-shaped projections 102c along the longitudinal fold lines LFL on the base section 102, which are opposite the wedge-shaped projections 104c and V-shaped pockets 104b of the receiving section 104, such that the wedge-shaped projections 104c interlock with the V-shaped pockets 102b and the wedge-shaped projections 102c interlock with the V-shaped pockets 104b (see Fig. 15G).

[0191] Using the longitudinal fold line LFL as the axis of rotation, the projections 104c are pulled out of the pockets 102b in a pulling step, as shown by arrows P3 in Fig. 15E. In a further pulling step, as shown by arrows P4 in Fig. 15F, the base section 102 and the receiving section 104 are brought into an angular position relative to each other, the final position of which is shown as the angled construct 100 in Fig. 15G. During the pulling step, the longitudinal fold line LFL changes its course into a zigzag configuration in the direction of the vertical axis HR.

[0192] The angle construct 100 is accordion-shaped, whereby the described folding and pulling steps, in particular the zigzag course of the longitudinal fold line LFL, ensure that the receiving section 104 remains independently in an angular position relative to the base section 102.

[0193] As shown in Figs. 15G and 15H, two adjacent sub-areas 102a are brought into contact with each other in alternating sequence, as indicated by the arrows P5, and bonded together by the adhesive surface 106, while adjacent sub-areas 102a are pulled into a plane, so that, as shown in Fig. 15J, the collection unit Al 3 is attached to the door T by means of the adhesive surface 106.

[0194] As shown in Fig. 151, the collecting unit Al 3 can adapt to curved outer contours of the object by means of smaller amplitudes between projections 104c and pockets 104b at the outer edge 104d. This is also possible along objects with varying curved outer contours (not shown).

[0195] In the embodiment shown, the supporting structure is represented by the base section 102, the collection part by the collection section 104 and the holding device by the adhesive surface 106.

[0196] In an embodiment not shown, the upper edges of the adjacent sub-areas 102a of the base section 102 are formed obliquely towards the receiving section 104.

[0197] In another embodiment, not shown, the holding device is formed by the base section 102 being ring-shaped, e.g., enclosed by adhesive, and thus able to be attached to the object. In yet another embodiment, not shown, the base section has holes at its upper ends through which a cord or rubber band is threaded, thereby forming the holding device. The angled structure 100 is designed such that, when a load below a first threshold is applied to the collecting section 104, it maintains its shape in such a way that a collecting function is preserved. However, when a load above a second threshold is applied to the collecting section 104, it is designed to be flexible, such that under load the angle between the collecting section 104 and the base section 102 increases, thus preventing the bird V from landing.The first threshold is determined by the weight of the collected droppings, while the second threshold is determined by the weight of the bird V.

[0198] Fig. 16A shows a sheet structure F12, which serves as the starting form for a collection unit A14 according to a fourteenth embodiment. The sheet structure Fl 2 is designed in the form of a composite structure VS1, consisting of a carrier paper 112 and a meanderingly wound wire 114, which is firmly connected to the carrier paper 112, e.g. by gluing.

[0199] Depending on the application of a force, the composite structure VS1 is either plastically or elastically deformable. Plastic deformation, which can be carried out manually by a user, creates a composite body 110, as shown schematically in Fig. 16B.

[0200] Fig. 16B shows the catch unit A14. As shown there, the composite body 110 consists of a holding section 110a, a base section 11 Ob, and a catch section 110c, which are formed integrally. The holding section 110a and part of the base section 110b are adapted to the shape of the door T and function as the holding device. The supporting structure is formed by the base section 110b and the catch section 110c, and the catch element is formed by the catch section 110c, which has a dual function as part of the supporting structure and as a catch element.

[0201] The composite body 110 has a length L in the longitudinal direction LR (Fig. 16A), a height H in the vertical direction HR and a width B in the horizontal direction BR (Fig. 16B) corresponding to the dimensions of the embodiment of Fig. 1A and 1B.

[0202] Fig. 16C shows a modified planar structure Fl 2a of the fourteenth embodiment, which differs from the embodiment shown in Fig. 16A in that an additional cover paper 116 is applied to the meanderingly wound wire 114, such that the wire 114 is sandwiched between the carrier paper 112 and the cover paper 116, so that a modified composite structure VS2 is formed.

[0203] Fig. 16D shows the collection unit A 14, which is installed at door T.

[0204] Fig. 16E shows a collection unit A 14.1 installed on the backrest Le of a chair St, which in this embodiment represents the object. The collection unit A14.1 consists of a composite body 110.1 based on the composite structure VS 1, but with two collection sections 110.1c arranged on either side of the backrest Le. The other features correspond to the composite body 110. Although not shown in detail, the plastic forming can also be executed in a curved shape, e.g., along a curved backrest Le.

[0205] Fig. 17A shows a sheet structure F13, which serves as the starting form for a collection unit Al 5 according to a fifteenth embodiment. The sheet structure Fl 3 is designed as a composite structure VS3, consisting of the carrier paper 112 and the meandering wire 114, which is firmly bonded to the carrier paper 112, e.g., by adhesive bonding. Furthermore, a mounting adhesive surface 118 is provided outside the area of ​​the wire 114.

[0206] In modified embodiments (not shown), instead of the meandering wire 114, a multitude of shorter wire pieces are used, which are arranged either almost parallel or randomly oriented. In a further modification of the illustrated embodiment, the mounting adhesive surface 118 extends into the area where the wire 114 is provided.

[0207] Fig. 17B shows the collection unit Al 5. As shown there, a composite body 120 formed on the basis of the composite structure VS 3 consists of a base section 120a and a collection section 120b, which are formed in one piece. The base section 120a is attached to the door T by means of the mounting adhesive surface 118, which acts as the holding device. The supporting structure is formed by the base section 120a and the collection section 120b, and the collection element is formed by the collection section 120b, which has a dual function as part of the supporting structure and as a collection element.

[0208] Fig. 17C shows a modified planar structure F13a of the fifteenth embodiment, which differs from the embodiment shown in Fig. 17A in that a cover paper 116 is additionally applied to the meandering wire 114, such that the wire 114 is sandwiched between the carrier paper 112 and the cover paper 116, forming a modified composite structure VS4. In this embodiment, the mounting adhesive surface 118 is provided on the cover paper 116.

[0209] Fig. 17D shows the collection unit Al 5, which is installed at door T.

[0210] The composite body HO, 110.1, 120 is designed such that, when subjected to a load below a first threshold value, the collecting section 110c, 120b retains its shape in such a way that its collecting function is maintained. However, when subjected to a load above a second threshold value, the collecting section 110c, 120b is designed to be flexible, such that under load the collecting section 110c, 120b moves away from the base section 110b, 120a, thus preventing the bird V from landing. The first threshold value is determined by the weight of the collected droppings, while the second threshold value is determined by the weight of the bird V.

[0211] Fig. 18 shows a side view of a collection unit Al 6 according to a sixteenth embodiment of the invention. The collection unit A16 is designed in the form of an angled structure 130, which is made in one piece from papier-mâché. The angled structure 130 consists of a base section 130a and a collection section 130b, which extends at an angle from the base section 130a.

[0212] Furthermore, the collection unit Al 6 is equipped with a mounting adhesive surface 132 in the area of ​​the base section 130a, by which the collection unit Al 6 is attached to the door T. The mounting adhesive surface 132 here functions as the holding device, the base section 130a and the collection section as the supporting structure, and the collection section 130b as the collecting element, whereby the collection section 130b has a dual function as part of the supporting structure and as a collecting element. Both the base section 130a and the collection section 130b are elastically deformable over a large area in such a way that a bird V is prevented from landing on the collection section 130b.

[0213] In a modified embodiment not shown, the transition between the base section 130a and the collecting section 130b is equipped with a weakened area that serves as a film hinge. A bistable spring or a correspondingly shaped area of ​​the papier-mâché material between the base section 130a and the collecting section 130b prevents the bird V from landing on the collecting section 130b.

[0214] The angled structure 130 is designed such that, when subjected to a load below a first threshold value, the collecting section 130b retains its shape in such a way that its collecting function is maintained. However, when subjected to a load above a second threshold value, the collecting section 130b is designed to be flexible, such that under load the angle between the collecting section 130b and the base section 130a increases, thus preventing the bird V from landing. The first threshold value is determined by the weight of the collected droppings, while the second threshold value is determined by the weight of the bird V.

[0215] Fig. 19 shows a side view of a collection unit Al 7 according to a seventeenth embodiment of the invention. The collection unit Al 7 is designed in the form of an angled structure 140, which comprises a base element 140a, a collection element 140b, and a leaf spring 142 connecting the base element 140a and the collection element 140b as an elastic device. The base element 140a and the collection element 140b are made of cardboard.

[0216] Furthermore, the collection unit Al 7 is equipped with a mounting adhesive surface 144 in the area of ​​the base element 140a, which is used to attach the collection unit Al 7 to the door T. The mounting adhesive surface 144 acts as the holding device, the base element 140a and the leaf spring 142 and the collection element 140b act as the supporting structure, and the collection element 140b acts as the collection component. The leaf spring 142 and the collection element 140b have a dual function. The elasticity of the leaf spring 142 prevents the bird V from landing on the collection element 140b.The angled structure 140 is designed such that, when subjected to a load below a first threshold value, the collecting element 140b maintains its angular position in such a way that its collecting function is preserved. However, when subjected to a load above a second threshold value, the collecting element 140b is designed to be flexible, such that under load the angular position between the collecting element 140b and the base element 140a increases, thus preventing the bird V from landing. The first threshold value is determined by the weight of the collected droppings, while the second threshold value is determined by the weight of the bird V.

[0217] Fig. 20 shows a side view of a collection unit Al 8 according to an eighteenth embodiment of the invention. The collection unit Al 8 has a support 200 extending over the width of the door T and a base section 200a, a holding section 200b, and a connecting section 200c. The connecting section 200c connects the base section 200a and the holding section 200b.

[0218] The bracket 200 is designed to be attached to an object, in this case, the door T. The connecting section 200c is dimensioned to match the thickness of the door T. The retaining section 200b serves to hold, i.e., to secure, the bracket 200 against displacement in the direction of the thickness of the door T, which is determined by the distance between the outer surfaces of the door T.

[0219] In another embodiment, the bracket 200 has at least two bracket elements (not shown) that are attached to the door T.

[0220] At one end 200al of the base section 200a, which is located away from the connecting section 200c, a support 204 is pivotally mounted via a hinge 202. This support is designed to carry a collecting strip 208, which serves as the collecting medium. A torsion spring 206, acting as an elastic element, is arranged between the base section 200a of the bracket 200 and the support 204. In modifications of the embodiment shown, a leaf spring or a tension spring is used between the bracket 200 and the support 204 instead of the torsion spring 206.

[0221] The collecting strip 208 rests on the support 204 and extends over the entire length of the support 204. In the preferred embodiment, the collecting element is made of paper. In this embodiment, the collecting element is represented by the collecting strip 208, the supporting structure by the base section 200a, the torsion spring 206, and the support 204, the holding device by the holding section 200b, the connecting section 200c, and a part of the base section 200a, and the device for preventing the bird V from landing is represented by the torsion spring 206.

[0222] The bracket 200 is designed such that, when a load below a first threshold is applied to the support 204, it maintains its angular position in such a way that its collecting function is preserved. However, when a load above a second threshold is applied to the support 204, it is designed to be flexible, such that under load the angular position between the support 204 and the base section 200a increases, thus preventing the bird V from landing. The first threshold is determined by the weight of the collected droppings, while the second threshold is determined by the weight of the bird V.

[0223] Fig. 21A shows a side view of a collection unit Al 9 according to a nineteenth embodiment of the invention. The collection unit Al 9 has a holder 210 and a rotatable axis 220.

[0224] As shown in Fig. 21B, the bracket 210 consists of two support walls 212, each equipped with a hook 212a for attachment to the door T. The rotatable axis 220 is mounted in each of the support walls 212 by means of a roller bearing 214 and extends along the longitudinal direction LR between the support walls 212 (see Fig. 21B and 2IC). In a modified embodiment, clamps are provided instead of the hooks 212a.

[0225] The retaining walls 212 are designed so that they run at an angle from the area of ​​the hooks 212a to the area of ​​the bearing of the axis 220, so that the bird V cannot find a foothold to perch on one of the retaining walls 212.

[0226] A flat structure in the form of a paper collection sheet 216 (see Fig. 2 ID) has a mounting adhesive surface 216a and two securing adhesive surfaces 216b. The mounting adhesive surface 216a serves to attach it to the door T, and the securing adhesive surfaces 216b are connected to the rotatable axis 220 (in the same manner as clearly shown in Fig. 22 A below) and serve to prevent the collection sheet 216 from completely detaching from the rotatable axis 220 when the bird V attempts to land.

[0227] In this embodiment, the collecting element is represented by the collecting arch 216, the supporting structure by the support walls 212 and the axis 220, the holding device by the hooks 212a of the support walls 212, and the device for preventing the bird V from landing by the rotatable axis 220 with the collecting arch 216 and the slopes of the support walls 212. In this embodiment, the axis 220 has a dual function as part of the supporting structure and as a device for preventing the bird V from landing.

[0228] Fig. 22A shows a side view of a collection unit A20 according to a twentieth embodiment of the invention. The collection unit A20 has a holder 230 and a rotatable axis 240.

[0229] The bracket 230 is formed in one piece and has a base section 230a, a holding section 230b and a connecting section 230c that connects the base section 230a to the holding section 230b.

[0230] The bracket 230 is designed to be attached to an object, in this case, the door T. The connecting section 230c is dimensioned to match the thickness of the door T. The retaining section 230b serves to hold, i.e., to secure the bracket 230 against movement on the door T.

[0231] A guide section 230d is integrally connected to the base section 230a. The guide section 230d serves to guide a collecting arch 236 located above the base section 230a. A support section 230e is provided at the end of the guide section 230d opposite the base section 230a. This support section 230e serves to support the rotatable axis 240. The support section 230e, which is arranged on both sides of the rotatable axis 240, is narrow in design, such that the bird V cannot perch on it. The axis 240 is supported by means of rolling bearings 234, which are arranged at both ends of the axis 240.

[0232] In this embodiment, the bracket 230 extends continuously along the door. In a modified embodiment, two brackets are provided, similar to the hook 212a of the nineteenth embodiment.

[0233] A flat structure in the form of a paper collection sheet 236 (see Fig. 22B) has a mounting adhesive surface 236a and two securing adhesive surfaces 236b. The mounting adhesive surface 236a serves to attach it to the door T, and the securing adhesive surfaces 236b are connected to the rotatable axis 240 and serve to prevent the collection sheet 236 from completely detaching from the rotatable axis 240 when the bird V attempts to land.

[0234] In this embodiment, the collecting element is represented by the collecting arch 236, the supporting structure by the base section 230a, the connecting section 230c, the roller bearings 234, and the axle 240, the holding device by the holding section 230b, the connecting section 230c, and part of the base section 230a of the support 230, and the device for preventing the bird V from landing by the rotatable axle 240. The rotatable axle 240 has a dual function as part of the supporting structure and as a device for preventing the bird V from landing.

[0235] Instead of the rolling bearings 234, plain bearings are provided in a modified version.

[0236] Fig. 23A shows a side view of a collection unit A21 according to a twenty-first embodiment of the invention. The collection unit A21 has a holder 250 and a rotatable axis 260.

[0237] The bracket 250 is formed in one piece and has a base section 250a, a holding section 250b and a connecting section 250c that connects the base section 250a to the holding section 250b.

[0238] The bracket 250 is designed to be attached to an object, in this case, door T. The connecting section 250c is dimensioned to match the thickness of door T. The retaining section 250b serves to hold, i.e., to secure the bracket 250 against movement on door T.

[0239] A guide section 250d is integrally connected to the base section 250a. The guide section 250d serves to guide a collecting arc 256, which is part of a roll 258 (see Fig. 23B) of interconnected collecting arcs 256. At an end of the guide section 250d opposite the base section 250a, a support section 250e is provided on each side of the axis 260. This support section 250e serves to mount the rotatable axis 260. The axis 260 is mounted on each support section 250e via a sliding bearing (not shown). The axis 260 can be removed from the sliding bearings to allow the roller 258 to be attached and is axially secured against displacement in the operating state (not shown).

[0240] As shown in Fig. 23C, the roll 258 consists of the connected collection sheets 256, each having an adhesive mounting surface 256a. Although not shown in detail, the adhesive mounting surfaces 256a are provided with protective strips to prevent the collection sheet 256 from sticking to the adhesive mounting surfaces 256a. Furthermore, perforations 256b are provided to facilitate the separation of a collection sheet 256 from the roll 258.

[0241] In this embodiment, the collecting element is represented by the collecting arch 256, the supporting structure by the base section 230a, the support sections 250e, the sliding bearings and the axis 260, the holding device by the holding section 250b, the connecting section 250c and a part of the base section 250a of the support 250, and the device for preventing the bird V from settling by the paper roll 258 on the rotatable axis 260.

[0242] In an embodiment not shown, based on the collection unit Al 9, a thin wire or cord is stretched between the support walls 212 instead of the rotatable axis 220, and a paper loop is placed over it. This thin wire or cord serves as the device to prevent the bird V from landing. In this embodiment, a cross brace is provided between the support walls 212 for stabilization.

[0243] In another embodiment, not shown, based on the collection unit Al 9, a rotatable axle stub is provided on each support wall 212 instead of the rotatable axle 220, over which a paper loop is placed. In a modification of this embodiment, the axle stubs are fixedly connected to the support walls 212. Fig. 24A shows a sheet structure Fl 4, which is provided as a blank for a collection unit A22 according to a twenty-second embodiment, as shown in Fig. 24B. The sheet structure F14 has the upper side S1 and the lower side S2 and has the base section 32B, the collection section 34, the strut section 36 and the connecting section 40A. Folding the fold lines FL1, FL2 and FL3 results in the collection unit A22 with a tubular structure 3 Oi, as shown in Fig. 24B.

[0244] In this embodiment, the first fold line FL1 is designed to fold in a second direction, pointing towards the upper side S1 of the surface structure F14, while the second and third fold lines FL2 and FL3 are designed to fold in the first direction, pointing towards the lower side S2 of the surface structure F14. Fold line FL1 is folded such that an acute or right angle is formed between the connecting section 40A and the collecting section 34 on the upper side S1.

[0245] In this embodiment, the bonding surface 42 is located on the lower side S2 of the base section 32B. The mounting surface 20 is located on the lower side S2 of the connecting section 40A. As shown in Fig. 24B, which depicts the collection unit A22 with the tubular structure 30i, one end 32B1 of the base section 32B is positioned so far from the first fold line FL1 that the entire bonding surface 42 lies above the first fold line FL1 in the vertical direction HR.

[0246] The connecting section 40A has a dimension in the vertical direction HR such that the mounting adhesive surface 20 and the connecting adhesive surface 42 fit completely within this space. Preferably, as shown in Fig. 24B, a vertical distance h between an end 32B1 of the base section 32B and between an end 40A1 of the connecting section 40A is dimensioned such that a distance a exists between the connecting adhesive surface 42 and the mounting adhesive surface 20.

[0247] The collection unit A22 is a modification of the collection unit A7, whereby the collection unit A22 is attached to the door T in the same way as the collection unit A7.

[0248] Fig. 25A shows a surface structure Fl 5, which is provided as a blank for a collection unit A23 according to a twenty-third embodiment, as shown in Figs. 25B and 25C. The surface structure Fl 5 has the upper side S1 and the lower side S2, has a base section 32K consisting of a first base area 32K1 and a second base area 32K2, has the collection section 34a and the strut section 36. The collection section 34a is divided into two sections 34a1 and 34a2 by the channel fold line FLR. The first base area 32K1 has two mounting adhesive surfaces 20 and the second base area 32K2 has one mounting adhesive surface 20.

[0249] Folding the fold lines FL1, FL2, FL3 and FLR results in the collection unit A23 with a folding structure 31, as shown in Figs. 25B and 25C. The folding structure 31 has a recess 33 extending longitudinally in the LR direction on the lower side S2.

[0250] In this embodiment, the first fold line FL1 is designed for folding in the second folding direction, which points towards the upper side S1 of the surface structure Fl 5, the second fold line FL2 is designed for folding in the first folding direction, which points towards the lower side S2 of the surface structure Fl 5, and the third fold line FL3 is designed for folding in the second folding direction, which points towards the upper side of the surface structure Fl 5.

[0251] The two sections 34al and 34a2 are inclined towards the depression 33. This forms the channel 35, which further optimizes the collection of bird V's droppings.

[0252] Figures 25B and 25C show the collection unit A23, which is arranged on the object, which is preferably planar. In the embodiment shown, the object is represented by the door T. The collection unit A23 is installed on the door T by means of the three mounting adhesive surfaces 20 of the base areas 32K1, 32K2 of the base section 32K. Thus, the collection section 34a, the strut section 36, and the planar surface of the door T define a cavity and form a tubular shape comparable to the tubular structure of the third to twelfth embodiments A3 to Al 2 and the twenty-second embodiment A22.

[0253] Fig. 26A shows a surface structure Fl 6, which is provided as a blank for a catch unit A24 according to a twenty-fourth embodiment, as shown in Figs. 26B and 26C. The surface structure F16 has the upper side S1 and the lower side S2, has the base section 32K, which consists of the first base area 32K1 and the second base area 32K2, has the catch section 34a and the strut section 36. The catch section 34a is divided into two sections 34a1 and 34a2 by the channel fold line FLR.

[0254] Folding the fold lines FL1, FL2, FL3 and FLR results in the collection unit A24 with a folding structure 31a, as shown in Figs. 26B and 26C. The folding structure 31a has a longitudinally extending depression 33 on the lower side S2.

[0255] In this embodiment, the first fold line FL1 is designed for folding in the second folding direction, which points towards the upper side S1 of the surface structure Fl 6, while the second fold line FL2 and the third fold line FL3 are designed for folding in the first folding direction, which points towards the lower side S2 of the surface structure Fl 6.

[0256] The two sections 34al and 34a2 are inclined towards the depression 33. This forms the channel 35, which further optimizes the collection of bird V's droppings.

[0257] Figures 26B and 26C show the collection unit A24, which is installed on the door T by means of the three mounting adhesive surfaces 20. The collection unit A23 is installed on the door T by means of the three mounting adhesive surfaces 20 of the base areas 32K1, 32K2 of the base section 32K. Thus, the collection section 34a, the strut section 36, the base area 32K2 and the flat surface of the door T define a cavity and form a tubular shape corresponding to the tubular construction of the third to twelfth versions A3 to Al 2 and the twenty-second version A22.

[0258] In the embodiments of the collection units A23, A24, one part of the supporting structure is formed by the base section 32K, the collection section 34a and the strut section 36, and another part of the supporting structure is formed by the door T and the collection part by the collection section 34a.

[0259] The operation of the collection units A23, A24 is comparable to the operation described in connection with Fig. 13.

[0260] In a modification of the collection units A23 and A24, only two mounting adhesive surfaces 20 are provided, one mounting adhesive surface 20 on the base area 32K1 and one mounting adhesive surface 20 on the base area 32K2.

[0261] The two mounting adhesive surfaces 20 on the first base area 32K1 are designed as a continuous adhesive surface in a modification of the collection units A23 and A24.

[0262] In a version differing from the collection units A23 and A24, the folding structure is pre-formed with a recess 33 extending through the longitudinal direction LR. Preferably, the folding structure is made from a stranded material, wherein the respective collection unit can be separated from the stranded material.

[0263] The feature that the at least one collecting element or at least one area thereof and / or the at least one supporting structure or at least one area thereof is designed to be deformable and / or movable and is returnable to its original position in such a way that the functionality of the at least one collecting element can be largely restored, is to be understood as meaning that the restored functionality can be achieved independently, as a result of elastic deformation or in the case of plastic or bistable / multistable deformation, with a few simple steps and without tools.

[0264] Taking into account the fact that dynamic forces may occur when the bird is put down, the static weight of the bird is used as the lowest value for setting the second threshold.

[0265] In the implementation forms, the collection units Al to A24 were depicted as objects attached to a door T or a chair St. Other objects that could be used, such as a cabinet, a computer screen, a shelf, and a shower cubicle, are given as examples.

[0266] Instead of providing a mounting adhesive surface, a fixing adhesive surface and / or a connecting adhesive surface on the respective collection unit itself, modified versions provide separate double-sided adhesive tape or another commercially available adhesive for mounting the respective collection unit on the object or for manufacturing the respective collection unit.

[0267] Instead of a single-piece collection unit in the longitudinal direction LR, in modified embodiments several similar collection units are joined together to form one collection unit, preferably overlapping.

[0268] In one embodiment, a large number of blanks are arranged separately on top of each other, so that a lower side S2 of one blank lies on the upper side S1 of another blank.

[0269] In another embodiment, a semi-finished product for manufacturing a multitude of blanks is designed in the form of a roll. In one embodiment, the vertical direction HR coincides with a winding direction of the roll, while in another embodiment, the longitudinal direction LR coincides with the winding direction of the roll.

[0270] Preferably, the roll already has the mounting adhesive surfaces 20 or the mounting adhesive surfaces 20 and the joining adhesive surfaces 42. In a further preferred embodiment, the fold lines FL1, FL2, FL3, FLR are additionally incorporated into the roll as perforations or fold grooves as a pre-product.

[0271] In one embodiment, the roll has a continuous structure, allowing the cut pieces to be separated to the desired length using a cutting tool, such as scissors. In another embodiment, the roll has perforations at intervals corresponding to the size of the cut pieces, perpendicular to the winding direction of the roll, which facilitates the separation of the cut pieces from the roll.

[0272] In a variant differing from the embodiment described above, a pre-product is designed with a continuous structure in the form of a leporello stack, wherein the upper side S1 of a section of the structure corresponding to a blank lies on the upper side S1 of an adjacent section of the structure corresponding to another blank, and a lower side S2 of one section lies on the lower side S2 of another section. In one embodiment, perforations are provided between the sections of the stack to facilitate the separation of the blanks from the stack.

[0273] The collection units A3 to A12 and A22, which have the tubular structure 30, 30a,..., 30i formed from a planar structure Fl to F10, F14, or the collection units A23 and A24, which have the folded structure 31, 31a, are designed in a form with perforations in the vertical direction HR to facilitate the separation of sections of the respective collection unit A3 to A12 and A22 or A23, A24.

[0274] In one embodiment, a semi-finished product is formed in a roll form with a continuous structure corresponding to a plurality of interconnected, flat-folded collection units A3 to Al2 and A22, each containing the tubular structure 30, 30a,..., 30i. The term "flat-folded" refers to a product in which the volume of the cavity 38 is reduced to a minimum, as explained, for example, in connection with Fig. 14. In a modification of this embodiment, perforations are provided in the vertical direction HR to facilitate the separation of individual collection units A3 to Al2 and A22.

[0275] In another embodiment, a continuous structure corresponding to a plurality of interconnected flat-folded collection units A3 to Al 2 and A22, each containing the tubular construct 30, 30a,..., 30i, is formed in the form of a leporello stack, such that the upper side S1 of a collection unit A3 to Al 2 and A22 lies on the upper side S1 of an adjacent collection unit A3 to Al 2 and A22, and the lower side S2 of a collection unit A3 to Al 2 and A22 lies on the lower side S2 of an adjacent collection unit A3 to A12 and A22.

[0276] In a modification of this design, perforations are arranged in the vertical direction HR between the collection units A3 to A12 and A22 to facilitate the separation of individual collection units A3 to A12 and A22.

[0277] The use of the aforementioned collection units Al to A24 offers the advantage that the bird droppings can be easily and quickly visually inspected in order to identify possible diseases of the bird V.

[0278] Using a biodegradable collection unit offers a particular advantage for composting, as bird droppings contain valuable fertilizer.

[0279] It should be noted that for better illustration the drawings are not to scale and the adhesive surfaces 20, 42, 42Li, 42Re, 44, 106, 118, 132, 216, 236a, 236b, 256a are shown enlarged with respect to their thickness.

[0280] Hybrid forms between the different embodiments and their modifications are part of the disclosure of this invention.
