The present application is directed to a collection container, collection assembly, shell segment, and method of manufacturing a collection container.

Collecting objects, for example fruits like apples, pears, guinces and similar, from the ground is comparatively cumbersome if done manually.

Therefore, efforts have been made to at least partially ease picking up fruits from the ground. Reference is exemplarily made to WO 2013/064660 Al which shows a fruit collector having a col- lecting basket made from a plurality of elastic, bulged wire straps which are clamped at their ends by two axial hubs to de ^¬ fine an overall bulged, convex collecting cage or basket. By rolling the collecting basket over a fruit lying on the ground, the wires where the fruit touches the basket are spread apart by the fruit such that the fruit can enter the container through the basket envelope made from the plurality of wires. The de ^¬ sign, manufacture, and assembly of such a collecting basket hav ^¬ ing the plurality of wires attached to the hubs are comparative ^¬ ly elaborate and laborious.

Therefore, it is an object of the invention to provide a possi ^¬ bility for facilitated, simplified and/or cost-effective manu ^¬ facture and assembly of a respective collection container. In particular a collection container, collection container shell segment, collection assembly, and method manufacturing a collec ^¬ tion container shall be provided which allow or provide facili ^¬ tated, simplified and/or cost effective manufacture and assem ^¬ bly, and preferably at the same time allow alleviated manual op ^¬ eration . This object in particular is accomplished by the features and subject matter of the independent claims. Embodiments in partic ^¬ ular also result from respective dependent claims. According to an aspect of the invention, a collection container shell segment is provided which is designed and arranged for be ^¬ ing assembled to at least one further, in particular structural ^¬ ly identical, collection container shell segment to constitute in the ordinary assembled state an outer shell, or the outer wall structure, or the envelope of an inner volume, of a collec ^¬ tion container.

According to a further aspect of the invention, a collection container, in particular implemented as a basket or cage, is provided and which is configured to be pivotable around a pivot axis and operable to pick up objects, such as fruits, by rolling the collection container over the objects in a pivoting movement to thereby pass the objects through the outer shell into the collection container. The proposed collection container compris- es an outer shell that is assembled from a predefined number, at least two, collection container shell segments, wherein each of the shell segments is designed or implemented according to at least one of the shell segment embodiments described herein. Ad ^¬ vantages and advantageous effects related to the collection con- tainer in particular result from advantages and advantageous ef ^¬ fects of the proposed shell segments.

According to a further aspect of the invention, a collection as ^¬ sembly is provided comprising at least one collection container according to at least one of the collection container embodi ^¬ ments described herein. The collection assembly may further com ^¬ prise a retaining bracket for pivotably retaining the collection container, and may further optionally comprise a handle for man ^¬ ual operation and adapted to be coupled to the retaining brack- et . Advantages and advantageous effects related to the collec ^¬ tion assembly in particular result from advantages and advanta- geous effects of the proposed shell segments and collection con ^¬ tainer .

According to a further aspect of the invention, a method of man- ufacturing a collection container according to at least one of the embodiments described herein is provided. Advantages related to the method in particular result from respective advantages described in connection with any embodiments of the shell seg ^¬ ment or collection container. Further, as will become inferred from the discussion below, the proposed method is comparatively simple, and may at the same time conducted comparatively cost- efficient .

In embodiments of the invention, the outer shell of the collec- tion container may be considered as a full shell, extending, with respect to a pivot axis, over a dihedral angle of 360°, i.e. defining the outer walls of the collection container over a full axial rotation. The outer shell, but also the collection container may in embodiments have a rotationally symmetrical structure respectively form.

The collection container in embodiments may be configured to be pivotable around a pivot axis, and adapted to roll or be rolled on and over the ground. The collection container further may be operable to pick up objects, such as fruits like apples and sim ^¬ ilar, by rolling the collection container over respective ob ^¬ jects, resting for example on the ground, in a pivoting movement of the collection container to thereby pass the objects through the outer shell into the collection container, for example by elastic deformation of a suitable section of the outer shell.

The collection container shell segment in embodiments may de ^¬ fine, in circumferential direction relative to the pivot axis, a predefined angular sector of the outer shell of the collection container, and may have, span or spread over a predefined dihe ^¬ dral angle relative to the pivot axis. The collection container shell segment in embodiments may con ^¬ stitute an arcuate sector of the collection container confined by two, with respect to the pivot axis, radial planes, i.e. two planes running through and containing the pivot axis, and mutu- ally rotated by the dihedral angle, or by at least one, in par ^¬ ticular two, tangential planes, i.e. planes extending parallel to the pivot axis.

A shell segment in embodiments may define, with respect to the assembled state of the collection container, and with respect to the pivot axis, a wedge-shaped sub-section or cut, i.e. segment, of the collection container, having a wedge angle corresponding to the dihedral angle. In other embodiments, a shell segment may define a layer or slice of the collection container confined between two mutually parallel tangential planes extending parallel to the pivot axis.

In further embodiments, a shell segment may define a cap defined by a single, with respect to the pivot axis, tangential plane.

In embodiments in which the shell segment defines a cap, as de ^¬ scribed beforehand, the collection container may be assembled from an upper and lower cap-like shell segment and an intermedi- ate slice or layer shaped shell segment defining a double-sided truncated section of the collection container.

Advantageously, the collection container shell segments for a certain collection container in embodiments may be designed such that the collection container may be assembled by a predefined number of structurally identical shell segments, i.e. of shell segments that are identical in construction.

In embodiments, the shell segments may be implemented and de- signed such that all of the shell segments from which the col ^¬ lection container is or is to be assembled are of identical con ^¬ struction. This for example can be obtained by using half or quarter shells or wedge-shaped shell segments having defined di ^¬ hedral angles .

As can be seen, the proposed collection container shell segment constituting a predefined dihedral angle section of an entire collection container, and which can be assembled with further, advantageously structurally identical, shell segments to span the whole collection container, is suitable to considerably re ^¬ duce assembly effort, manufacture and manufacturing costs for the collection container. In particular, a collection container for collecting objects in the sense of the present invention may be assembled by the use of for example merely two half-shells or, for example, four quarter shells. This clearly is suitable for reducing assembly effort, particularly as compared to known solutions necessitating each single wire strap to be individual ^¬ ly mounted or fixed to axial hubs.

In embodiments, the dihedral angle spanned by the predefined an ^¬ gular sector lies in at least one of the ranges 30 - 180 °, 45° - 135°, and 60° to 90°.

In case that the shell segments are constructed such that they can be assembled and set together without overlap, excluding or neglecting an overlap established at possible connector inter- faces and connector elements such as latching elements, provided for mutually engaging adjoining shell segments, the sum of the dihedral angles of the shell segments in the assembled state of the collection container may be about, preferably equal, 360°, in particular meaning that the shell elements define the collec- tion container all along its whole circumference. In case that adapter pieces or similar intermediate elements between adjoining shell elements are use or provided, or in case that adjoin ^¬ ing shell segments overlap in circumferential direction, the sum of the dihedral angles of the shell segments constituting the collection container may lie below or above 360°. Using dihedral angle ranges as mentioned above, a predefined, and, in view of assembly effort, convenient number of shell seg ^¬ ments may be provided. As an example, shell segments each having a dihedral angle of 180° may be provided, meaning that the collection container can be assembled from two half-shells.

As another example, shell segments each having a dihedral angle of 90° may be provided, meaning that the collection container can be assembled from four guarter-shells .

It shall be noted that also other dihedral angles and a differ ^¬ ent number of shell segments, such as three shell segments or six shell segments, may be provided. Further, it is noted that the shell segments assembled to a collection container need not have egual dihedral angles. In view of this, a selection of shell segments constituting in the assembled state the collec ^¬ tion container may have two cap-shaped shell segments and an in- termediate slice-type shell element or layer, respectively de ^¬ fined by different dihedral or circumferential angles and inter ^¬ secting planes relative to the pivot axis. In other variants, the connection container may be assembled from a half-shell and two guarter shells, respectively spanning different dihedral or circumferential angles. Other configurations are conceivable.

In general, shell segments constituting a collection container may be defined or obtained by dividing the outer shell of the collection container by intersecting planes selected or placed in such a way that severing of the envelope of the collection container, in particular elastic straps defining such an envelope, is avoided over the axial length of the collection con ^¬ tainer . As can be seen, by the design and configuration of the proposed shell segments, the assembly of the collection container may be considerably facilitated due to a limited number assembly parts and comparatively easy mounting procedures .

Improvements with respect to assembly effort and cost may be ob- tained if shell segments are used that are structurally identi ^¬ cal. This in particular applies in cases where all of the shell segments needed for the assembly of a single collection contain ^¬ er are structurally identical. In view of using structurally identical shell segments only a restricted number of manufacturing forms or molds, for example for injection molding the shell segments, may be reguired. Spe ^¬ cifically, in case that all of the shell segments for assembling a single collection container are structurally identical, a sin- gle manufacturing form for the shell segments may be sufficient, which clearly is an advantage in view of manufacturing cost reduction .

As already indicated, in embodiments, the shell segments provid- ed for the assembly of a single collection container may be im ^¬ plemented as half-shells or guarter-shells .

In embodiments, the shell segment may be implemented as an inte ^¬ gral, one-piece part. In this case, the shell segment may be made from a plastic material. Plastic materials for manufactur ^¬ ing the shell element may be processed by using injection mold ^¬ ing technigues .

Providing the shell segments as one-piece parts, advantageously made by injection molding, may be effective in reducing the number of assembly parts thereby reducing the assembly effort and complexity for assembling a collection container.

In embodiments, the collection container may be implemented as a collection basket or cage. Such a basket or cage may comprise a plurality of elastic threads or straps, preferably having a wire-type or wire-shape configuration, and extending in length- wise direction in accordance with the pivot axis of the collec ^¬ tion container.

The threads or straps may be designed to extend between both ax- ial ends of the collection container in a direction transversely to the circumferential direction of the collection container relative to the pivot axis.

The plurality of threads or straps may span or constitute a cir- cumferential envelope of the collection container, which enve ^¬ lope, due to the elasticity of the threads or straps, is permea ^¬ ble for objects to be collected with the collection container. In particular the threads or straps may be made from an elastic plastic material by using injection molding technigues.

In embodiments, the collection container shell segment may com ^¬ prise at each axial end an axial hub segment. The hub segments may be designed to define axial terminal parts of the collection container .

In embodiments, the hub segments may be interconnected in axial direction, i.e. in axial direction relative to the pivot axis, by a plurality of elastic threads or straps, in particular as previously described. The treads provided in axial direction be- tween the axial bubs are mutually spaced in circumferential di ^¬ rection relative to the pivot axis. Further, the threads or straps are designed and arranged such that they can be elas- tically deformed and pushed or forced apart in circumferential direction, such that an object, intended to be collected, can be passed through a gap generated between for example a group of neighboring threads or straps, in that the threads or straps are elastically forced or pushed apart in circumferential direction. The threads or straps may in variants be bulged radially out ^¬ wards to define or form a bulged collection container of convex structure. In embodiments, the collection container shell segment may com ^¬ prise, at an axial end thereof, at least one axial hub segment, wherein the axial hub segment is implemented as a ring segment, forming a part of an axial hub, configured for example as an ax- ial flange or stub axle section, which axial hub in the assem ^¬ bled state of the collection container, may be pivotably coupled with a counterpart hub of a retaining bracket for the collection container . The axial hub segment, in particular the ring segment, may be designed such that the threads or straps emanate or originate from the hub or ring segment at certain mutually spaced loca ^¬ tions along the circumferential direction. In particular, the axial hub segment and threads or straps may be manufactured in a one-piece integrated form.

The straps in embodiments may form a grid of non-crossing grid elements in form of the axial straps. However, embodiments with crossing straps shall not be excluded.

In embodiments in which both axial ends of the collection con ^¬ tainer are provided with an axial hub segment, which may for ex ^¬ ample be implemented as described above, the threads or straps may interconnect between both axial hub segments and may be in- tegrally formed in a one-piece configuration with both axial hub segments. In this case, the shell segment may be considered to constitute a single assembly unit, suitable for the reduction of the overall number of assembly parts, and for facilitating and easing assembly of the collection container.

In embodiments, in which the shell segment comprises an axial hub segment which is implemented as a ring segment, it may be provided that an inner radius of the ring segment is such that, in the assembled configuration of the collection container, an axial discharge opening for discharging objects collected in the collection container is established at an axial end of the col ^¬ lection container. This shall mean, that the inner radius of the ring segment is configured, preferably selected sufficiently large or small, such that the finally assembled collection con ^¬ tainer comprises at the axial end an axial discharge opening having a size or diameter such that objects, such as fruits, collected with and resting within the collection container can be discharged from the collection container via the discharge opening .

As can be seen, the proposed design and assembly of a collection container using several shell segments makes it possible to flexibly adapt the collection container to different needs or reguirements . In particular, the manufacturing process for the collection container can be flexibly adapted to structural or design changes of the collection container.

In embodiments, in which the collection container comprises at least one axial hub segment, in particular as described further above, at least one of the hub segments may be implemented as an axial circular wall segment. In this case, the axial hub of the collection container in the assembled state, may be implemented as a closed wall section, and a stub axle section configured for pivotably coupling the collection container to for example a re ^¬ taining bracket can be established or provided at an outer sur ^¬ face of the axial wall section.

It has to be noted, that the proposed design and assembly of the collection container having several shell segment components makes it possible to flexibly adapt the collection container to different needs or reguirements, in particular in the region of the axial end sections of the collection container. Thus, the manufacturing process for the collection container as proposed herein even in case of structural or design changes of the col ^¬ lection container may be easily and flexibly adapted whilst keeping and securing comparatively easy and straightforward mounting and assembly processes for the collection container. In embodiments comprising an axial hub segment implemented as an axial circular wall segment, such as with the embodiment de ^¬ scribed above, defining an axial circular wall of the collection container, the axial wall segment may comprise at an outer axial side an axial protrusion defining a segment of an axial stub ax ^¬ le intended to cooperate, in the assembled state, with a coun ^¬ terpart hub or bearing shell of for example a retaining bracket.

As can be seen, with the modular concept and assembly of the collection container as proposed herein, according to which sev ^¬ eral shell segments are combined to form a single collection container, it is in particular possible to implement functional or structural elements such as an axial stub axle. Functional as well as structural elements may be implemented by suitably splitting or dividing respective functional element in sections or segments of the shell segments, such that, when setting to ^¬ gether the shell segments, the overall shape and geometry of re ^¬ spective functional or structural elements is established, pref ^¬ erably without reguiring additional or extra assembly and/or mounting steps.

In embodiments, for example related to the modular design of the collection container as proposed herein, which comprise at least one hub segment, at least one of the hub segments may comprise at least one connector or latching interface.

The latching interface in embodiments may comprise snap connect ^¬ ors, such as plug-and-snap connectors like a snap-tongue or snap-pin, and one or several corresponding snap-recesses.

The connector or latching interface may in embodiments comprise at least one connector or latching structure or connector or latching member, designed for engagement, in the assembled state of shell segments, with a counterpart connector or latching structure of a counterpart connector interface of an adjoining shell segment . The connector interfaces may be considered to take account of the modular structure and assembly of the collection container defined by the use of several shell elements and as proposed herein. The connector interfaces and connector structures may be considered to enable easy and straightforward interconnection of the single shell segments to form the collection container.

In embodiments, in which a connector interface is provided, the connector interface may comprise at least one of: at least one locking or latching extension, and at least one latching recess.

The latching extension may be configured and adapted to engage, in the assembled state of the shell segment it belongs to, into a corresponding latching recess of a connector interface of an adjoining shell segment. Further, the latching recess may be configured and adapted to engage, in the assembled state, a latching extension of a connector interface of the or a further adjoining collection container shell segment. In embodiments, the connector interface at least in part may be formed at or on at least one axial flange of the collection con ^¬ tainer shell segment . The axial flange may be implemented at or on or in connection with an axial hub segment and/or axial pro ^¬ trusion, which have been described in detail further above.

Specifically, in embodiments, a connector interface may be pro ^¬ vided on or at the axial protrusions provided on an outer axial side of an axial wall segment of the shell segment, in particu ^¬ lar in such a way that a coupling or connecting force or effect is generated or obtained in the assembled state in the region of a stub axle made up by the axial protrusions.

In embodiments, the connector interface may be provided and ori ^¬ ented in circumferential direction, which in particular shall means that adjoining shell segments may be held together by forces acting in circumferential direction. Further, providing the connector interfaces at respective circumferential faces, comparatively easy assembly operations can be achieved.

In embodiments, in which the shell segments comprise axial hub segments or axial stub axle segments making up, in the assembled state of the collection container, an axial hub or axial stub axle, it may be provided that a respective axial hub and axial stub axle are accommodated and embraced, for example in circum ^¬ ferential and optionally in axial direction, by respective coun- terpart hubs, for example bearing shells, of a retaining struc ^¬ ture, such as a retaining bracket, configured to pivotably re ^¬ tain the assembled collection container. Implementing the hub and/or stub axle such that it/they can be embraced by a counter ^¬ part hub or bearing shell of suitable design may be advantageous for the overall mounting process, because specific and separate fixing elements may be dispensed with. In addition, by using, providing or enabling a circumferential embracement, improved support and stability may be obtained for the collection con ^¬ tainer .

In embodiments of the connection container, each shell segment may define, in circumferential direction relative to the pivot axis, a predefined angular sector of the outer shell of the col ^¬ lection container. The shell segment in embodiments may have, with respect to the pivot axis, a predefined dihedral angle, wherein the sum of the dihedral angles of the predefined number of shell segments preferably eguals 360°. Regarding the sum of the dihedral angles, reference is additionally made to the dis ^¬ cussion further above, indicating that, depending on the specif- ic design of the shell segments, the sum of the dihedral angles may exceed or be lower than 360°, depending on the overlap or distance between adjoining shell segments in circumferential di ^¬ rection . Coming now to embodiments of the proposed method, embodiments of a method of manufacturing a collection container may comprise the steps of : a. manufacturing a predefined number of collection container shell segments embodied at least in accordance to at least one of the embodiments as described here ^¬ in, each shell segment defining, in circumferential direction relative to the pivot axis, a predefined angular sector of the outer shell of the collection container, having, with respect to the pivot axis, a predefined dihedral angle, wherein the sum of the di ^¬ hedral angles of the predefined number of shell seg ^¬ ments advantageously eguals 360°; b. assembling and putting together the shell segments by interconnecting corresponding connector interfaces of adjoining shell segments to obtain, with respect to the pivot axis, a circumferential full shell defining the outer shell of the collection container.

In account of the above discussion, it can be seen, that the shell segment, collection container, collection assembly, and method of manufacturing a collection container are suitable for obtaining or achieving the object identified further above.

In further embodiments, a retaining bracket, in particular a retaining frame or retaining structure may be provided that is im ^¬ plemented to be used with a collection container according to any embodiment described herein. In particular, a retaining bracket or frame may be provided that is able to pivotably re ^¬ tain or support the collection container, which may be implemented as a collection basket.

In embodiments, an adapter unit arranged to be releasably cou ^¬ pled to a counterpart adapter unit of for example a handle may be associated, in particular fixedly or releasably mounted, to the retaining bracket. The counterpart adapter unit may for ex ^¬ ample be associated with a handle, such that the fruit collect- ing tool can be releasably coupled to the handle for manual op ^¬ eration .

In embodiments, the collection assembly, retaining bracket, and/or collection container may either be specifically adapted to a special fruit/object or may be configured to be used with and/or customized to a certain number of fruits or objects of similar shape. In embodiments, the retaining bracket may be configured such that it can accommodate different types of collection containers respectively adapted to collect a specific type of object or fruit, e.g. apples, peaches, nuts, and so on. The retaining bracket may be adapted for multiple uses with different types or sizes of collection containers .

According to a further aspect of the invention that may be sepa ^¬ rately claimed, a collection system or kit may be provided that comprises at least one retaining bracket and at least one col- lection container set together from shell segments as described herein, or at least one retaining bracket and at least a number of shell segments as described herein suitable to be set togeth ^¬ er or assembled to form at least one collection container. The kit may be adapted such that different types, sizes or shapes of collection containers, in particular specifically adapted to collect different types, sizes or shapes of fruits can be used. Such a kit in particular may comprise a number of fruit or object collecting tools having pivotable collection containers that can be coupled with a respective handle. Each fruit collecting tool may comprise a separate retaining bracket associated with a corresponding collection container and corre ^¬ sponding shell segments according to any embodiment described herein. However, it is also possible that the collecting tools comprise a uniform retaining bracket and a certain number of collection containers in which each of the collection containers is configured to be coupled to the uniform retaining bracket . In embodiments, the uniform retaining bracket may be fixed in shape and adapted to be coupled to a single collection container or to a certain number of different collection containers. In particular, different types of collection containers may be con ^¬ figured to be coupled with the uniform retaining bracket. Alter ^¬ natively, the retaining bracket may be implemented to be varia ^¬ ble in shape and/or form, such that it can be adapted to differ ^¬ ent shapes and/or forms of collection containers. However, also in the embodiment with variable retaining bracket, a certain setting of the retaining bracket in form or shape may be provid ^¬ ed that is able to cooperate with several types of collection containers adapted to said certain setting. In such a system or kit, the collector assembly can easily be adapted to the collection of different kinds of fruits or ob ^¬ jects, for example by exchanging the type of fruit collection tool and/or the collection container. At least the retaining bracket and collection container of such a system or kit may be embodied in accordance with any embodiment or variant as de ^¬ scribed herein.

The retaining bracket in embodiments may be implemented to pivotably support or retain the collection container in such a way that the collection container is pivotable around a major axis of rotation. The axis of rotation, or pivot axis in partic ^¬ ular may coincide with an axis of symmetry, in particular an ax ^¬ is of rotational symmetry, of the collection container. In embodiments, the collection container may comprise an oblong or prolong structure, i.e. it may have a structure in which a dimension in axial direction, in particular parallel to or coin ^¬ ciding with the pivot axis, is larger than a dimension in trans ^¬ verse, radial direction, or it may have a structure in which the dimension in axial direction is smaller than the dimension in transversal, in particular radial, direction. In embodiments, the retaining bracket may comprise a spout that is configured to pass through fruits or objects to be collected or drained from the collection container. The spout may be con ^¬ figured to let pass through objects into and out of the collec- tion container. In embodiments, the spout may extend and open in a direction parallel and/or inclined to a pivoting axis defined by the retaining bracket.

In embodiments, the spout may be integrally formed with the re- taining bracket. Here, the spout and retaining bracket may form and define a single-part component. In such embodiments, the spout may be fixedly and immovably attached to or implemented at the retaining bracket . In other embodiments, the spout may be provided as a separate component and may be configured to be mounted or connected to the retaining bracket. In particular in such embodiments, the spout may be movably attached to the retaining bracket. In em ^¬ bodiments, the spout, or at least a section thereof, may be at- tached or mounted such that it can be swivelled and/or rotated relative to pivot axis of the retaining bracket.

In further embodiments, the spout may be implemented such that the direction and orientation of an open end of the spout facing away from collection container in the assembled state, and de ^¬ fining a type of collection mouth or emptying opening can be al ^¬ tered in a rotating and/or swivelling movement of the spout or the moveable section thereof. In this way, the spout can be ad ^¬ justed to best suit fruit collecting reguirements and user- specific operating conditions.

In embodiments, the opening plane of an outer opening of the spout may be implemented in such a way, that in an optimal or average operational condition of the fruit collector related to a rolling collection operational mode, an angle in counter ^¬ clockwise sense between a vertical plane running through the pivot axis and an intersecting plane running through the pivot axis and coinciding with a centre plane of the bracket lies in the range between 30 and 60 degrees, in particular in the range of about 55 degrees. In embodiments, the collection container may comprise or may be defined inter alia by an envelope, defining, with respect to the pivot axis, a circumferential, in particular elastic, envelope that is permeable for fruits to be collected or intended to be collected.

The envelope may in embodiments comprise a plurality of elastic sections or elements designed and implemented such that an ob ^¬ ject, in particular fruit, lying on the ground can elastically deform a certain number of the elastic elements to thereby pass through the envelope and get from the outside to the inside of the collection container upon rolling the collection container over or moving it over the object.

In embodiments, the elastic sections may comprise wires or wire bars made from a plastic, metal material and/or composite mate ^¬ rial, in particular reinforced material.

In particular embodiments, the wire bars, may have a diameter in the range between 1.0mm to 1.5mm, or 1.1mm to 1.4mm, or 1.25mm to 1.3mm. Such diameters may provide sufficient bendability and at the same time sufficient flexibility to allow collecting of objects, in particular fruits, without significantly injuring the surface of the collected objects, and allowing manufacture by injection moulding and similar.

A collection container having an envelope in accordance with the embodiment mentioned above may be rolled on the floor or ground by a user, whereby objects can be picked up by rolling the col ^¬ lection container over the objects such that respective objects elastically deform and the envelope to generate an entrance opening or entrance gap for penetrating the envelope. Penetra ^¬ tion of the envelope involving elastic deformation of the enve- lope may occur for example in a direction transversal to the pivot axis .

In embodiments the retaining bracket, in particular the base section thereof, may comprise a clutch, in particular a stand ^¬ ardized clutch, or coupling adapted to exchangeably couple the retaining bracket to a counter-clutch provided on a handle, such as a multi-functional handle. A connection between the counter- clutch and clutch may be of push-and-snap type, or may comprise a screw fastening mechanism, or others.

In embodiments, the collection container may comprise at an axi ^¬ al end thereof a stub axle section having a central through-hole or discharge opening sized and dimensioned so as to enable ob- jects to be collected to move or be moved into the collection container, wherein the stub axle section may be configured to cooperate or to be coupled with a bearing shell of the retaining bracket. The discharge opening or through-hole may be used to collect fruits by moving objects through the opening into the collection container, but may primarily be used for discharging objects out of the collection container. The discharge opening may be adapted such that one object at a time can pass through.

In embodiments, the stub axle section may comprise a bearing or sliding surface, for example of a segmented ring-shaped configu ^¬ ration, which may be adapted to cooperate in the mounted state with a counterpart bearing or sliding surface of a bearing shell of the retaining bracket. The bearing or sliding surface may be an inner or also an outer surface, wherein the counterpart bear- ing or sliding surface of the hub then may be implemented as an outer or inner surface .

In embodiments, one of the bearing or sliding surfaces may com ^¬ prise friction reducing or guiding components, structures or structural elements suitable for reducing friction between the bearing or sliding surfaces and/or for obtaining proper guidance of the bearing or sliding surfaces, in particular for restrict- ing movement or play or clearance of the bearing or sliding surfaces in axial direction. These friction reducing components or structural elements may comprise protrusions and/or depressions, in particular beads and/or bulges and the like, suitable for re- ducing frictional forces acting between the sliding or bearing surfaces and/or for generating adeguate guidance. The friction reducing components or structural elements may for example be provided in axial and/or radial direction relative to the pivot axis, and may in addition be configured to avoid jamming of a pivoting movement of the collection container, and for example may be implemented slip rings.

In embodiments, the collection container may comprise an addi ^¬ tional or a further stub axle section implemented at an axial end of the collection container, wherein the additional stub axle section may be implemented as a shaft configured to cooperate with a corresponding bearing shell implemented at the retaining bracket . The further stub axle section may comprise a plate hub with a centred axle stub or shaft projecting therefrom. The axle stub or shaft may be configured in such a way that it can cooperate with a bearing shell or bearing mounting of the retaining bracket .

FIG. 3 shows one of the guarter shell segments 10 of the collec ^¬ tion container 3 of the collection assembly 1 as shown in in FIG. 1 and FIG. 2.

The shell segment 10, in accordance with the embodiment shown in FIG. 3 is implemented as a guarter shell segment 10, which means, that the outer shell of the collection container 3 is composed of four (i.e. 4) shell segments, wherein each of the shell segments in the embodiment in view of the circumferential direction relative to the pivot axis P covers a dihedral angle a (alpha) of 360° * ¾ = 90° . The dihedral angle a (alpha) spanned by the shell segment 10 may be defined by radial planes running through the pivot axis and confining the shell segment 10 in circumferential direction, wherein elements, such as latching elements of connector interfaces projecting in circumferential direction and overlapping with adjoining shell sections in the assembled state preferably are disregarded in determining the dihedral angle.

Thus, the dihedral angle of embodiments of the shell segment may be defined as an angle confined between radial planes defined by the circumferential extension of the shell segment, excluding however sections overlapping with adjoining shell sections in the assembled state.

It shall be noted, that in different embodiments of the collec ^¬ tion container 3, the shell segments may have dihedral angles a (alpha), i.e. different from 90°, and that dihedral angles of shell segments constituting a collection container 3 in the assembled state may have mutually different dihedral angles.

The shell segment 10 shown in the embodiment of FIG. 3 may be made as one-piece integrated part, in particular from plastic in a moulding process. In this way, shell segments 10 and therefore also the collection container 3 may be manufactured comparative ^¬ ly easily and cost-efficient. As shown in the embodiments according to the figures, the shell segment (s) 10 are structurally identical, and a collection con ^¬ tainer 3 therefore can be assembled by mounting together four identical shell segments 10. In accordance with the embodiments shown in the figures, it can be inferred that the use of identical shell segments 10 may re ^¬ sult in a generally rotationally symmetric form of the collec ^¬ tion container 3. Such a configuration may be preferable in view of the intended use of the collection container by collecting objects in a rolling over motion, which will be described further below. As can be concluded from the above discussion, assembly of the collection container can be accomplished in a comparatively sim ^¬ ple, uncomplicated, and cost-effective way. It shall be noted, that this also applies for embodiments in which the collection container 3 is split into less than four shell segments 10, and still applies for embodiments in which the collection container 3 is split into more than four shell segments 10. As shown in the exemplary embodiments in the figures, for example FIG. 3, the shell segment 10 may comprise at each axial end 11.1 and 11.2 an axial hub segment 12.1 and 12.2. The axial hub segments 12, in the assembled state define the axial end shape and configuration of the outer shell 10 of the collection con- tainer 3.

The outer shell 10 of the collection container 3 may, as shown in the exemplary embodiments shown in the figures, further be defined by, bulged straps 13 extending in axial direction be- tween and interconnecting the axial hub segments 12.

The bulged straps 13, which in the embodiment have a wire or filament like longitudinal structure may be made from the same material as the axial hub segments 12, and further may be formed integrally with the axial hub segments 12. The straps 13 are de ^¬ signed and implemented such that they are elastically deformable or bendable, wherein a major direction of elastic deformability may correspond to the circumferential direction. The deformabil ^¬ ity may be such that neighbouring straps 13 can be pushed apart in circumferential direction to thereby enlarge a gap 14 between at least two adjacent straps 14.

The straps 13 may, as shown in the embodiments in the figures and in view of their overall form, be bent outwardly so as to form, in the assembled state, a collection container 3 having a bulged, convex structure, which may have a rotationally symmet ^¬ ric geometry. Specifically, as can be seen from FIG. 3, the straps 13 may in embodiments have a form, in which they extend, starting from the axial hub segments 12, first essentially parallel to the axial direction and then bulge outwardly according to a predefined curvature thus defining the final shape and geometry of the out ^¬ er shell of the collection container 3 in circumferential direc ^¬ tion . As can be seen from the embodiment shown in FIG. 3 and FIG. 4, in which FIG. 4 shows a half shell segment assembled from two guarter shell segments according to FIG. 3, the axial hub seg ^¬ ment 12.1 located at the right-hand side in FIG. 3 and FIG. 4 comprises an axial circular wall segment 15, in particular in the form of disc-like segment, defining in the assembled state a section of a closed axial wall of the outer shell of the collec ^¬ tion container 3.

The axial hub segment 12.1 may further comprise an axial flange section 16 extending, with respect to the assembled state, axi- ally inwardly, and defining a circumferential base from which the straps 4 extend in axial direction.

As shown in the figures, the axial wall segment 15 may comprise at an outer axial side an axial protrusion 17 defining a segment of the stub axle section 8.1 (see FIG. 2) established on the right-hand axial hub section 6. The axial stub axle 8.1 is de ^¬ signed to cooperate, in the assembled state of the collection container, with the bearing shell 7.1 located on the right-hand side of the retaining bracket 2 as shown in FIG. 1 and FIG. 2.

As exemplarily shown in the embodiments of FIG. 2 to FIG. 4 and in particular FIG. 5 showing a detail of FIG. 4, the axial pro ^¬ trusion 17 as well as the axial flange section 16 of the axial circular wall segment may, as shown for example in FIG. 2, com ^¬ prise connector elements or a connector structure, for example in the form of latching tongues 18 projecting therefrom in cir- cumferential direction. Further, the axial protrusion 17 as well as the axial flange section 16 may comprise at sides averted from the latching tongues 18 counterpart connector elements, for example in the form of counterpart latching recesses 19.

The connector elements and counterpart connector elements may be designed such that they define connector interfaces, and may be implemented for mutual engagement . As can be seen from the embodiment in the figures, the latching tongues 18 and latching recesses 19 may be designed such that the latching tongues 18 of an adjoining, preceding shell segment 10 can latch into the latching recesses 19, and such that the latching tongues 18 can latch into the latching recesses of a subseguent shell segment 10, thereby holding together the shell segments 10 in the assembled state. Cohesion of the shell seg ^¬ ments 10 in the assembled state in particular may be supported in that the stub axle section (s) 8 is/are enclosed by the bear ^¬ ing shells of the retaining bracket 2 pivotably supporting the collecting basket 3.

It shall be noted, that the stub axle section 8.2 located on the left-hand side in FIG. 2 may, but must not, comprise similar connector interfaces such that a latching engagement can be ob- tained at the left-hand axial hub 6 of the collection contain ^¬ er 3.

As can be seen from the exemplary embodiment shown in FIG. 3 and FIG. 4, the left-hand axial hub segment 12.2 may be implemented as as a ring segment 12.2 forming part of an axial hub in the assembled state of the collection container, which is adapted to be pivotably coupled with the left-hand bearing shell (cf. FIG. 2) of the retaining bracket 2. As can be seen from the embodiments shown in particular in FIG. 2, FIG. 4, and FIG. 6 showing two half shell segments according to FIG. 4 shortly before assembly, an inner radius of the ring segment 12.2 may be implemented such that in the assembled con ^¬ figuration of the collection container 3 an axial discharge opening 20 for discharging objects collected in the collection container 3 is established. Such a discharge opening 20 may be of advantage for a quickly and easily discharge of collected ob ^¬ jects from the collection container 3. Regarding the modular design of the collection container 3 assembled from several shell segments 10, it provides for a comparatively easy implementation of such discharge openings while at the same time still securing easy and uncomplicated assembly and manufacture.

Below, an exemplary way of assembling the collection container 3 from four quarter shells is explained on the basis of FIG. 1 to FIG. 7, wherein FIG. 7 shows a detail of FIG. 6. This general assembly principle also applies for collection containers having a higher or lower number of shell segments 10.

In an initial step, a predefined number of shell segments 10 (cf. FIG. 3) may be provided, for example by manufacture.

In a subsequent step, the single shell segments 10 may be com ^¬ bined and set together, wherein the latching tongues 18 and latching recesses 19 of adjoining shell segments 10 may be latched with each other.

For example, two of the quarter shell segments 10 may be com ^¬ bined to a first half shell as shown in FIG. 4 and FIG. 5 where ^¬ in corresponding latching elements mutually engage. Then, a sec ^¬ ond half shell may be assembled from two further quarter shell segments 10, and the two half shell segments finally may be com ^¬ bined to form the outer shell of the collection container 3, which is exemplarily indicated in FIG. 6. and FIG. 7.

As can be inferred from FIG. 6 and FIG. 7, upon setting the two half shell segments together, the latching tongues 18 projecting from the half shell segments enter and latch with corresponding latching recesses 19 to thereby hold together the four shell segments 10 to form the collection container 3, at least, however, the outer shell thereof.

In a further (optional) mounting step, the assembled collection container 3 may be coupled to the retaining bracket 2 by engag ^¬ ing the stub axle sections 8 with their corresponding bearing shells 7 in order to pivotably couple the collection container 3 to the retaining bracket 2. By mounting the collection container 4 to the retaining bracket 3, which may be obtained by compressing the collection container in axial direction and fitting it to the retaining bracket 3, the sliding surfaces 18, 19 mutually engage so that the collec ^¬ tion container 4 is pivotably supported on the retaining brack- et 3.

In view of the above, it can be inferred, that the collection container 3 and collection assembly as proposed herein enable comparatively easy and straight forward assembly, mounting and manufacture, and at the same time enable structural flexibility, which shall mean, that form, shape and structure of the collec ^¬ tion container, such as for example the discharge opening, can be adapted within a comparatively broad range without impairing easy and uncomplicated assembly. Therefore, the underlying ob- ject of the invention can be considered to be achieved by the embodiments according to the invention as described herein.

Below, an exemplary mode of operation for the collection assembly and collection container is described in connection with FIG. 8 and FIG. 9, in which FIG. 8 and FIG. 9 respectively show a side view and perspective view related to ordinary operational modes of the collection assembly.

The collection container 3 pivotably held or attached to the re- taining bracket 2 is designed such that it can be rolled in a pivoting movement on the ground, which is indicated as a forward movement in FIG. 8 by an arrow pointing to the right hand side. For manually operating the collection assembly, the bracket 2 may be coupled via the adapter section 9 with a counterpart adapter section 21 implemented at a handle 22 configured to be held by the operator in order to roll the collection container 3 over the ground.

In case that the collection container 3 while rolling on the ground reaches an object 23 of sufficient rigidity, such as for example an apple, and the collection container 3 is rolled over the object 23, the object 23 may pass the envelope defined by the circumferential straps 13 of the collection container 3 and enter the collection container 3. For entering the collection container 3, the object 23, upon rolling the collection container 3 over the object 23, will cause a group of neighbouring straps 13 of the envelope to elas- tically bend and spread apart such that, by the elastic defor ^¬ mation, a gap is generated in the envelope through which the ob- ject 23 can pass and penetrate the envelope. Upon entering the collection container 3, the gap will be closed or removed again by the elastic resilient forces of the straps 13.

Thus, by rolling the collection container 3 over the object 23, the object 23 is collected into the collection container 3 through the envelope by elastic deformation thereof.

As can be seen from FIG. 8 and FIG. 9, the retaining bracket 2, for example at a respective bearing shell, may comprise on an outer side thereof a spout 24. The spout 24 may be in integral design in a one-piece configuration with the retaining bracket 2 in form of a bent pipe end section.

As can for example be seen from FIG. 1 and FIG. 2, the spout 24 may have an inner opening communicating and being aligned with the axial discharge opening 20 of the collection container 3. By utilizing the spout 24, it is possible to empty the collec ^¬ tion container 3 and discharge the objects 23 collected therein through the spout 24. The collection container 3 may be emptied by twisting (see curved arrow in FIG. 9) the collection assembly such that the spout 24 faces downwards so that objects 23 con ^¬ tained in the collection container 3 may exit via the spout 24 by the action of gravity.

Thus, it is not required to discharge collected objects 23 through strap structure of the envelope of the collection con ^¬ tainer 3, and therefore, discharging objects 23 collected in the collection container 3 can be greatly simplified.
