Description

[0001] Support device

[0002] The present invention relates to a support device for a roll of web-like material, in particular toilet paper.

[0003] In Germany alone, per capita consumption amounts to several dozen toilet paper rolls per year. In Germany alone, this equates to several billion cardboard tubes of waste per year, which is also associated with high and therefore detrimental CO2 emissions, for example. State-of-the-art toilet paper rolls without cardboard tubes are known in this context, and these can significantly increase the number of sheets and significantly reduce the amount of waste. A challenge, however, is that these cardboard-tube-free toilet paper rolls are generally not dimensionally stable, particularly when held in place by corresponding holders. For example, when unrolling such toilet paper rolls, the unrolling movement may be uneven and / or halting and / or they may even become jammed in a corresponding holder.In addition, if the toilet paper roll is almost completely unrolled and / or used up, it may become so deformed that it is no longer possible to continue unrolling it.

[0004] A further challenge with such cardboard core-free toilet paper rolls can be transport-based deformation, which can prevent and / or complicate smooth and / or even unrolling of the affected rolls right from the start of use.

[0005] The present invention is therefore based on the object of solving the aforementioned problems, in particular of providing a preferably reusable support device for a roll of web-shaped material, in particular toilet paper, which is in particular easy and / or ergonomic to handle.

For example, a single piece base body can be non-destructively disassembled and / or dismantled. For example, a multi-piece base body can have multiple components that can be connected to one another. For example, a multi-piece base body can be non-destructively disassembled and / or dismantled.

[0124] The first component can be made of an elastic material. An interior space for accommodating the second component can be arranged and / or formed in the first component. The interior space can taper from one end of the first component to the other end of the first component, for example, with an inclination of 1° to 5°, e.g., 2°. The support surface is arranged on an outer side of the first component facing away from the interior space.

[0125] The second component can preferably be complementary to the first component and / or designed as a corresponding counter-component. The second component can be made of a non-elastic and / or rigid material. The receiving space can be arranged and / or formed in the second component. An outer side of the second component facing away from the receiving space can be inclined from one end of the second component to the other end of the second component, for example with an inclination of 1° to 5°, e.g. 2°, and preferably with an inclination corresponding to said inclination of the first component.

[0126] It can be provided that a minimum outer diameter of the second component is smaller than a maximum inner diameter of the first component, whereby the second component can be inserted into the interior of the first component, in particular easily and / or without counterforce, in particular to enlarge the outer diameter of the first component, so that it can be converted into the said effective outer diameter.

[0127] It can be provided that by inserting the second component into the interior of the first component, the first component is elastically deformable or is deformed in order to be convertible into a supporting state and / or to be converted into the supporting state.

[0128] In a certain sense, it can be provided that first the first component is insertable and / or is inserted into the roller and then the second component is insertable and / or is inserted into the first component in order to enable the said support state.

[0129] It can be provided that a beveled and / or chamfered region is included and / or formed at a respective, in particular front-side, end region and / or end of the base body. In particular, it can be provided that an outer and / or front-side edge of the base body, which is located in the end region and / or at the end, is beveled and / or chamfered, whereby the support device can advantageously be inserted into the roller more easily and / or smoothly.

[0130] It can be provided that the base body can be and / or is produced by injection molding, in particular 2K injection molding, or by extrusion.

[0131] Preferably, the base body can be manufactured and / or produced from one or more recyclable plastics.

[0132] For example, the base body can be manufactured and / or produced at least partially or entirely from a thermoplastic, in particular polypropylene (PP), e.g., recycled polypropylene (PP), and / or polyethylene (PE) and / or polyamide (PA). For example, the base body can be manufactured and / or produced at least partially or entirely from an elastomer plastic and / or at least partially from a thermoplastic elastomer plastic.

[0138] It can be provided that the base body, and in particular its wall, has a molding slope, preferably on the inside and / or outside, which extends from one end of the base body to the other end of the base body. In a sense, a minimal taper of the base body can thus be provided along the insertion direction in order to enable simpler and / or smoother release and / or removal of the support device from a production machine, e.g., an injection molding machine, and in particular from a tool of the production machine.

[0168] Identical or functionally equivalent elements are provided with the same reference numerals in all figures.

[0169] In Figs. 1 to 3, a support device 100 for a roll 102 of web-shaped material according to an embodiment of the present invention is shown schematically.

[0170] The web-like material could be toilet paper or kitchen roll paper, for example. However, it should be understood that this is purely exemplary.

[0171] In the following, the present invention is described by way of example in connection with toilet paper or a toilet paper roll (cf. Figs. 5 and 6).

[0172] The support device 100 has a base body 104 which is formed in one piece.

[0173] The support device 100 can be inserted into the roller 102 along an insertion direction 106.

[0174] The insertion direction 106 can be understood as a bidirectional direction. To a certain extent, it can be provided that the support device 100 can be inserted into the roller 102 from both sides of the roller 102 along the insertion direction 106.

[0175] The base body 104 is formed along a longitudinal axis 108, which is oriented parallel to the insertion direction 106. To a certain extent, a longitudinal extension of the base body 104 can be oriented along the longitudinal axis 108 and / or the insertion direction 106. Furthermore, a transverse extension of the base body 104 can be oriented transversely and preferably perpendicularly to the longitudinal axis 108 and / or the insertion direction 106.

[0176] The base body 104 is cylindrical and in particular circular-cylindrical.

[0177] A ratio of the transverse extent of the base body 104 to the longitudinal extent of the base body 104 is in the present case from 1 to 2.25 to 1 to 2.5, for example approximately 1 to 2.375±10%.

[0178] In this case, the transverse extension is a maximum transverse extension, in particular the outer diameter of the base body 104.

[0179] Preferably, the transverse extent of the base body 104 is from 30 mm to 50 mm.

[0180] Preferably, the longitudinal extension of the base body 104 is from 80 mm to 110 mm.

[0181] The base body 104 surrounds a receiving space 110.

[0182] The receiving space 110 preferably serves to receive a holding device 112 for the support device 100 and / or the roller 102 (see Figs. 5 and 6).

[0183] The receiving space 110 is formed along the longitudinal axis 108 and thus along the insertion direction 106 in the base body 104.

[0184] The receiving space 110 is open on both sides with respect to the longitudinal axis 108.

[0185] In a sense, the receiving space 110 extends along an entire length of the base body 104.

[0186] A support surface 114 for supporting the roller 102 is formed on the base body 104.

[0187] The support surface 114 is arranged on an outer side 116 of the base body 104 facing away from the receiving space 106. A wall 122 of the base body 104 extends between the support surface 114 or the outer side 116 and an inner surface 118 of the base body 104, which is arranged on an inner side 120 of the base body 104 facing the receiving space 110.

[0188] In a sense, the base body 104 has a wall 122.

[0189] The wall 122 has a wall thickness which is at least predominantly present and / or constant.

[0190] In the present embodiment, the wall thickness is preferably 2 mm ± 30%, in particular 2 mm ± 20%, for example 2 mm ± 10%.

[0191] The base body 104 has several sections 124, 126, 128. In the present case, a first section 124, a second section 126, and a third section 128 are provided.

[0192] Sections 124, 126, and 128 are integrally formed with one another and are connected. Sections 124, 126, and 128 therefore cannot be disassembled and / or dismantled without causing damage.

[0193] At least one section 124, 126 of the base body 104 is movable and / or deformable, for example reversibly and / or elastically deformable, to reduce a volume 130 of the receiving space 110 and / or to reduce an effective outer circumference 132 of the support surface 114.

[0194] This serves to insert the support device 100 into the roller 102.

[0195] As can be seen in particular in Fig.3, at least one section 124, 126 of the base body 104 is movable and / or deformable inwards to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0196] In the present case, the effective outer circumference 132 of the support surface 114 can refer to that outer circumference of the support surface 114 by means of which support of the roller 102 by the support device 100 is possible and / or by means of which the support surface 114 can be applied to an inner side of the roller 102 in order to support the roller, either partially or essentially completely. The effective outer circumference 132 can be seen, for example, in Figs. 1 and 2. If at least one section 124, 126 of the base body 104 is moved inward and / or deformed to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114, the support device 100, and in particular the base body 104, assumes an insertion state.

[0197] The insertion state can also be described as a volume-reduced state and / or as an outer circumference-reduced state.

[0198] When the support surface 114 rests against an inner side of the roller 102 in order to support the roller 102 in sections or substantially completely, the support device 100 and in particular the base body 104 assumes a support state.

[0199] As can be seen in Figs. 1 to 3, the base body 104 has two joint devices 134, 136, here a first joint device 134 and a second joint device 136, and a closure device 138.

[0200] The closure device 138 serves to open and / or close a contour 140 of the base body 104.

[0201] Here, the contour 140 refers to a cross section of the base body 104, which is oriented transversely and in particular perpendicularly to the insertion direction 106, and / or to a frontal view of the base body 104, which can be seen in Figs. 2 and 3.

[0202] A closed state of the contour 140 can be seen in Fig. 1 and 2. An open state of the contour 140 can be seen in Fig. 3.

[0203] The first joint device 134 is arranged between the first and third sections 124, 128.

[0204] The second joint device 136 is arranged between the third and the second section 128, 126.

[0205] The closure device 138 is arranged between the first and second sections 124, 126. In the present case, the closure device 138 is arranged partially on the first section 124 and partially on the second section 126 and / or is formed by them.

[0206] In the area of ​​the closure device 138, an overlap 142 of the adjacent sections 124, 126 is also provided, whereby improved stability can be achieved.

[0207] The contour 140 can be opened and / or closed by means of the closure device 138 based on force closure and / or form closure. In other words, the closure device 138 can be closed and / or closable based on force closure and / or form closure.

[0208] It may be conceivable here, for example, that a locking element and / or a clamping element of the closure device 138 is arranged and / or formed on the first section 124 and a corresponding counter-element of the closure device 138 is arranged and / or formed on the second section 126, which can interact with the locking element and / or clamping element, whereby the closure device 138 can be opened and / or closed and thus also the contour 140 of the base body 104.

[0209] Additionally or alternatively, a snap-lock-like closure device 138 may be conceivable and / or interlocking coupling elements, which may be integrated into the relevant sections 124, 126.

[0210] When the closure device 138 is opened, the first section 124 is movable inward via the first hinge device 134 and the third section 128 is movable inward via the second hinge device 136.

[0211] In a sense, the first section 124 is movable via the first joint device 134 and the third section 128 is movable via the second joint device 136 in the direction of the second section 126 when the closure device 138 is opened.

[0212] As can be seen from Fig. 3, the base body 104 has a substantially spiral-shaped contour 140 in the volume and / or outer circumference reduced state.

[0213] To a certain extent, the base body 104 can be folded and / or moved together and / or deformed in a spiral shape in order to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0214] Thus, the base body 104 can have a substantially spiral-shaped contour 140 in the volume and / or outer circumference reduced state.

[0215] The base body 104 can therefore have a substantially spiral-shaped contour 140 in the inserted state.

[0216] Via the joint devices 134, 136, the respective sections 124, 126, 128 are designed to be flexible and / or resilient and / or elastic relative to one another.

[0217] The first and second joint devices 134, 136 are arranged and / or formed on the inside, i.e. on the inside 120, of the base body 104.

[0218] The first and second joint devices 134, 136 extend inwardly in the direction of the insertion direction 106 along the entire base body 104.

[0219] A joint axis of a respective joint device 134, 136 is thus substantially parallel to the insertion direction 106 and / or to the longitudinal axis 108.

[0220] In order to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114, the relevant sections 124, 128 are movable and / or deformable about the respective joint axes, preferably movable and / or deformable inwards.

[0221] The first and second joint devices 134, 136 are formed integrally with the respective sections 124, 126, 128 and / or are integrally connected thereto.

[0222] In the present case, the respective sections 124, 126, 128 and the respective joint devices 134, 136 are made of a single material. However, it is conceivable for the sections and joint devices to be made of different materials. For example, it is conceivable for the respective joint device to be made of a material that is more elastic than the material of the respective sections, preferably by injection molding, in particular two-component injection molding. As can be seen from Figs. 1 to 3, the joint devices 134, 136 are provided at irregular angular intervals from one another on the base body 104.

[0223] In the present case, the first joint device 134 is spaced approximately 135° from the second joint device 136 (cf. the marked 45° angle in the center of the receiving space 110), wherein the first joint device 134 is arranged between the second joint device 136 and the closure device 138.

[0224] Due to the overlap 142, the closure device 138 extends over an angular range of approximately 45°.

[0225] The closure device 138 is spaced approximately 45° from the first hinge device 134 and approximately 135° from the second hinge device 136.

[0226] As already described, the base body 104 has the said wall 122, which surrounds the receiving space 110 at least in sections or completely in the radial direction and on which the support surface 114 is provided on the outside.

[0227] As can be seen particularly in Figs. 2 and 3, the first and second joint devices 134, 136 are formed by a reduction in the wall thickness of the wall 122.

[0228] In a sense, the first and second joint devices 134, 136 are designed like film hinges.

[0229] A groove 144 is formed in the wall 122 by a respective joint device 134, 136, in particular a respective wall thickness reduction.

[0230] The groove 144 runs along the base body 104 in the direction of the insertion direction 106.

[0231] The groove 144 has a trapezoidal cross-section.

[0232] The respective joint device 134, 136 and in particular the respective groove 144 has an opening angle which is oriented inwards.

[0233] The opening angle in this case is from 45° to 135°, preferably approximately 55° ± 20% or approximately 55° ± 10% or approximately 55° ± 5%. The wall thickness reduction in this case is from 50% to 95%, for example approximately 50%.

[0234] In the present embodiment, the joint devices 134, 136 are of identical design. However, it is also conceivable for the joint devices to differ at least partially from one another, in particular to be designed at least partially differently from one another.

[0235] The base body 104 can be produced and / or is produced by injection molding, in particular 2K injection molding, or by extrusion.

[0236] Preferably, the base body 104 can be produced and / or is produced from one or more recyclable plastics.

[0237] For example, the base body 104 can be produced and / or manufactured at least partially from a thermoplastic material, in particular polypropylene (PP) and / or polyethylene (PE) and / or polyamide (PA).

[0238] For example, the base body 104 can be manufactured and / or produced at least partially from an elastomer plastic and / or at least partially from a thermoplastic elastomer plastic.

[0239] In the following, a possible handling sequence of the previously described support device 100 is shown as an example:

[0240] A support device 100 and a roll 102 of web-like material, preferably toilet paper, are provided by a user.

[0241] The locking device 138 is opened by the user.

[0242] Subsequently, the first section 124 is moved inward and / or toward the second section 126 by the user via the first joint device 134 and the third section 128 is moved inward and / or toward the second section 126 via the second joint device 136.

[0243] This results in a reduction of the volume 130 of the receiving space 110 as well as a reduction of the effective outer circumference 132 of the support surface 114. The support device 100 is now small enough and / or has a reduced volume and / or reduced outer circumference to be easily and as resistance-free as possible inserted into the roller 102 along the insertion direction 106.

[0244] The support device 100 and in particular the base body 104 now has a substantially spiral-shaped contour 140.

[0245] The user then inserts the support device 100 along the insertion direction 106 into a space located in the center of the roll 102. This space can preferably be at least approximately circularly cylindrical.

[0246] When the support device 100 is inserted into the roll, the user moves the relevant sections 124, 128 back again and closes the contour 140 again by means of the closure device 138, so that the support device 100 is in a support state or the support state already described.

[0247] When the roll of web-like material or the toilet paper is used up, the support device 100 can advantageously be used again.

[0248] In Fig. 4 to 6, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0249] The embodiment of the support device 100 shown in Figs. 4 to 6 is substantially configured and / or designed like the embodiment of the support device 100 shown in Figs. 1 to 3, so that only the differences are described below.

[0250] The base body 104 has a closed contour 140.

[0251] In particular, the base body 104 is free of any locking device.

[0252] The base body 104 has three sections 124, 126, 128 and three joint devices 134, 136, 146.

[0253] The first joint device 134 is arranged between the first and second sections 124, 126. The second joint device 136 is arranged between the second and third sections 126, 128.

[0254] A third joint device 146 is arranged between the third and the first section 128, 124.

[0255] The first and second joint devices 134, 136 are arranged and / or formed on the inside of the base body 104, i.e. on the inside 120, relative to the receiving space 110.

[0256] The third joint device 146 is arranged and / or formed on the outside of the base body 104, i.e. on the outer side 116, relative to the receiving space 110.

[0257] The first and second joint devices 134, 136 are arranged opposite each other.

[0258] The third joint device 146 is evenly spaced from the first and second joint devices 134, 136, in this case arranged centrally.

[0259] At least the second section 126 is also elastic, in particular made of an elastic material.

[0260] The base body 104 is preferably manufactured by injection molding, for example 2K injection molding.

[0261] The base body 104 is formed in one piece.

[0262] The joint devices 134, 136, 146 are integrally formed and / or connected to the respective sections 124, 126, 128.

[0263] It may be conceivable that the joint devices 134, 136, 146 are each designed as a foil-flex hinge, preferably with a low profile, and / or have such a hinge.

[0264] The first and second joint devices 134, 136 are of similar design. The third joint device 146 has a larger opening angle than the first and second joint devices 134, 136.

[0265] The opening angle of the first and second joint devices 134, 136 is preferably approximately 90° ± 20% or approximately 90° ± 10% or approximately 90° ± 5%.

[0266] The opening angle of the third joint device 146 is preferably approximately 120° ± 20% or approximately 120° ± 10% or approximately 120° ± 5%.

[0267] The joint devices 134, 136, 146 or the respective grooves 144 have a triangular cross-section.

[0268] The first section 124 is movable inwardly via the first joint device 134.

[0269] The third section 128 is movable inwardly via the second joint device 136.

[0270] The third joint device 146 is movable inwardly and / or in the direction of the second section 126 via an inward movement of the first and / or the third section 124, 128.

[0271] During an inward movement of the first and third sections 124, 128, a distance between the first and second joint devices 134, 136 initially increases and, after passing a reversal point, said distance decreases again and is preferably smaller in the volume- and / or outer circumference-reduced state than in the support state.

[0272] As indicated in Fig. 4 by the dashed line, the base body 104 has a substantially heart-shaped contour 140 in the volume and / or outer circumference reduced state.

[0273] To some extent, the base body 104 can be folded and / or moved together and / or deformed into a heart shape to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114. The elastic property of the second section 126 is utilized to enable a bending, preferably reversible bending or deformation, opposite the third joint device 146.

[0274] In particular, the support device 100 can be inserted into the roller 102 in this state.

[0275] Such an inserted state and / or support state of the support device 100 is shown in Figs. 5 and 6.

[0276] A handling sequence of the support device 100 of Fig. 4 to 6 is essentially analogous to the already described handling sequence of the support device 100 of Fig. 1 to 3.

[0277] Furthermore, an exemplary holding device 112 is shown in Figs. 5 and 6.

[0278] The holding device 112 has a substantially U-shaped holding bracket 148, which can be fastened in an environment, e.g., to a room wall, via one leg of the holding bracket 148 by means of two mounting bases 150 and which can be inserted into the receiving space 110 of the support device 100 via another leg of the holding bracket 148 and is inserted in the present case.

[0279] At a respective end of the further leg of the retaining bracket 148, a retaining element 152 and a spacer element 154 are provided, between which the support device 100 with the roller 102 can be positioned and / or is positioned, in particular during use.

[0280] With particular reference to Figs. 4 to 6, it should be understood that more than three joint devices 134, 136, 146 can also be provided. For example, six or nine joint devices arranged on the outside and / or inside can also be provided, so that the reduction of the volume 130 of the receiving space 110 and / or the reduction of the effective outer circumference 132 of the support surface 114 can be made even further and / or more effective. To a certain extent, it is conceivable that the base body 104 can be made even smaller in this way.

[0281] As can be seen from Figs. 5 and 6, the present invention also relates to a combination of a support device 100 for a roll 102 of web-like material, in particular toilet paper, and a roll 102 of web-like material, in particular toilet paper. The support device 100 is configured according to the above and / or following description, and the roll 102 can preferably be arranged on the support device 100.

[0282] In Fig. 7, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0283] The embodiment of the support device 100 shown in Fig. 7 is substantially configured and / or designed like the embodiments of the support device 100 shown in Figs. 1 to 6, so that only the differences are described below.

[0284] The base body 104 has an open contour 140.

[0285] The base body 104 is free of joints.

[0286] The base body 104 is designed to be flexible and / or resilient and / or elastic.

[0287] In a sense, all sections, i.e. the entire base body 104, are designed to be flexible and / or resilient and / or elastic.

[0288] For example, the base body 104 can be made of an elastic material.

[0289] For volume and / or outer circumference reduction, a portion of the base body 104, which is arranged on one side of the region in which the contour 140 is open, can be moved under a portion of the base body 104 opposite thereto.

[0290] For this purpose, guide bevels 156 are preferably provided on the respective sections of the base body 104 in the region of the contour opening in order to enable a guided movement of one section under the other section.

[0291] As can be seen from the dashed line in Fig. 7, the base body 104 has a substantially spiral-shaped contour 140 in the reduced-volume and / or outer-circumference state. To a certain extent, the base body 104 can be spirally compressed and / or deformed to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0292] Thus, the base body 104 can have a substantially spiral-shaped contour 140 in the volume and / or outer circumference reduced state.

[0293] The base body 104 can therefore have a substantially spiral-shaped contour 140 in the inserted state.

[0294] It is understood that, additionally or alternatively, an overlap region of the respective sections of the base body 104 can be provided in the region of the contour opening shown. It is also conceivable, for example, that this overlap region can be formed by means of the guide bevels 156 shown.

[0295] In Fig. 8, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0296] The embodiment of the support device 100 shown in Fig. 8 is substantially configured and / or designed like the embodiment of the support device 100 shown in Fig. 7, so that only the differences are described below.

[0297] The support device 100 of Fig. 8 further comprises an elastic element 158, which in the present case is designed as a leaf spring-like spring element.

[0298] The elastic element 158 ​​is arranged in the receiving space 110 and lies at least partially or completely against the base body 104 and in particular its inner surface 118.

[0299] If the base body 104 is moved and / or deformed to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114, a restoring force can be exerted on the base body 104 by means of the elastic element 158. To a certain extent, the elastic element 158 ​​can force the support device 100 back into the support state.

[0300] This may enable a more stable support of the roller 102 and / or a contact pressure of the support surface 114 against the roller 102.

[0301] It should be understood that such an elastic element 158 ​​can optionally also be provided in the other embodiments described here and can have an analogous effect there.

[0302] Furthermore, it should be understood that such an elastic element 158 ​​can also be arranged on the outside of the base body 104. To a certain extent, it is conceivable that the elastic element 158 ​​is arranged on the support surface 114 and at least partially abuts the base body 104. In this case, for example, respective end regions of the elastic element 158 ​​can penetrate the wall 122, for example at specific points, to secure the elastic element 158 ​​to the base body 104.

[0303] In Figs. 9 and 10, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0304] The embodiment of the support device 100 shown in Figs. 9 and 10 is substantially configured and / or designed like the embodiments of the support device 100 shown in Figs. 1 to 6, so that only the differences are described below.

[0305] The base body 104 has a closed contour 140 which is largely circular.

[0306] The base body 104 is cylindrical, for example almost circular-cylindrical and / or cylindrical with a non-circular base area.

[0307] The base body 104 is free of joints.

[0308] The base body 104 is partially flexible and / or resilient and / or elastic.

[0309] The base body 104 has four sections 124, 126, 128, 160. The first and third sections 124, 128 are convex relative to an external view of the base body 104.

[0310] The second and a fourth section 126, 160 are concave relative to the external view of the base body 104.

[0311] The first and third sections 124, 128 are concave with respect to the receiving space 110.

[0312] The second and a fourth section 126, 160 are convex with respect to the receiving space 110.

[0313] At least the second and fourth sections 126, 160 are elastic and are preferably made of an elastic material, preferably by means of injection molding, for example 2K injection molding.

[0314] All sections 124, 126, 128, 160 are integrally formed with one another and / or cannot be disassembled and / or disassembled without destruction.

[0315] By applying a force, preferably a compressive force, to the first and / or the third section 124, 128, the second and the fourth section 126, 160 can be moved and / or deformed inwards to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0316] This enables the insertion state of the support device 100.

[0317] The elastic properties of the second and fourth sections 126, 160 also enable the support device 100 to be transferred back into the support state.

[0318] In Fig. 11, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0319] The embodiment of the support device 100 shown in Fig. 11 is essentially configured and / or designed like the embodiment of the support device 100 shown in Figs. 9 and 10, so only the differences are described below. The contour 140 is essentially circular.

[0320] The base body 104 is circular-cylindrical in shape.

[0321] At least the second and fourth sections 126, 160 are elastic and are preferably made of an elastic material, preferably by means of injection molding, for example 2K injection molding.

[0322] All sections 124, 126, 128, 160 are integrally formed with one another and / or cannot be disassembled and / or disassembled without destruction.

[0323] By applying a force, preferably a compressive force, to the first and / or the third section 124, 128, the second and the fourth section 126, 160 can be moved and / or deformed inwards to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0324] Preferably, a limiting force is exerted on the second and fourth sections 126, 160 in order to enable an inward movement and / or deformation of the respective sections 126, 160.

[0325] This enables the insertion state of the support device 100.

[0326] The elastic properties of the second and fourth sections 126, 160 also enable the support device 100 to be transferred back into the support state.

[0327] In Fig. 12, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0328] The embodiment of the support device 100 shown in Fig. 12 is substantially configured and / or designed like the embodiment of the support device 100 shown in Figs. 9 and 10, so that only the differences are described below.

[0329] All sections 124, 126, 128, 160 are elastic and preferably made of an elastic material, preferably by injection molding, for example, two-component injection molding. By applying a force, preferably a compressive force, to sections 124, 126, 128, 160, all sections 124, 126, 128, 160 can be moved inward and / or deformed to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114, as can be seen from the dashed contour line.

[0330] In Fig. 13, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0331] The embodiment of the support device 100 shown in Fig. 13 is essentially configured and / or designed like the embodiments of the support device 100 shown in Figs. 9 to 11, so that only the differences are described below.

[0332] The contour 140 is essentially polygonal, here octagonal.

[0333] The base body 104 is thus cylindrical with a non-circular base surface, here a polygonal base surface.

[0334] In a sense, the base body 104 is prism-shaped.

[0335] The base body 104 has eight sections, wherein the sections are alternately arranged elastically or not.

[0336] The elastically formed sections 162 are preferably made of an elastic material.

[0337] By applying a force, preferably a compressive force, to all sections, the sections can be moved and / or deformed inwards to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0338] Fig. 14 schematically shows a support device 100 for a roll 102 of web-like material, in particular toilet paper, according to another embodiment of the present invention. The embodiment of the support device 100 shown in Fig. 14 is essentially configured and / or designed like the embodiments of the support device 100 shown in Fig. 13, so that only the differences are described below.

[0339] The base body 104 has eight sections, wherein the sections are alternately arranged to be either: flexible and / or resilient and / or elastic, or not.

[0340] The flexible and / or resilient and / or elastic sections 162 are in the present case designed as bellows-like sections.

[0341] The base body 104 can be manufactured from a single material.

[0342] The base body 104 can be manufactured by injection molding or by extrusion.

[0343] By applying a force, preferably a compressive force, to all sections, the sections are movable and / or deformable inwards to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114, in particular since at least the bellows-like sections 162 are movable and / or deformable, preferably in an accordion-like manner and / or elastically.

[0344] In Fig. 15, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0345] The embodiment of the support device 100 shown in Fig. 15 is substantially configured and / or designed like the embodiments of the support device 100 shown in Figs. 1 to 8, so that only the differences are described below.

[0346] The base body 104 is formed from a spiral element 164.

[0347] The spiral element 164 extends helically around the longitudinal axis 108 along the insertion direction 106.

[0348] The base body 104 can be inserted into the roller 102 by means of a rotational movement 166 and a pushing movement 168. The base body 104 can be twisted by the rotational and pushing movements 166, 168 in conjunction with a frictional force acting against said movement 166, 168 between the base body 104 and the roller 102.

[0349] As a result, at least a portion of the base body 104, here a part of the spiral element 164, can be inwardly movable and / or deformable, in particular reversibly and / or elastically deformable, in order to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0350] In Fig. 16, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0351] The embodiment of the support device 100 shown in Fig. 16 is substantially configured and / or designed like the embodiments of the support device 100 shown in Figs. 1 to 8, so that only the differences are described below.

[0352] The base body 104 is made up of several parts, in this case two parts.

[0353] The multi-part base body 104 has two components 170, 172, here a first component 170 and a second component 172, which can be connected to one another.

[0354] It is understood that it may also be conceivable that the embodiments of the support device 100 described in connection with Figs. 1 to 15 may be designed with a multi-part, in particular two-part, base body 104 as further embodiments, wherein the respective components of the multi-part base body 104 may, for example, be overlapping with one another, engageable and / or spaced apart from one another, preferably in the inserted state in the roll.

[0355] Referring again to Fig. 16, the multi-part base body 104 can be disassembled and / or disassembled without destruction.

[0356] The base body 104, which can be assembled and / or composed of the components 170, 172, is circular-cylindrical in shape.

[0357] The first and second components 170, 172 can be assembled and / or detached from one another along the insertion direction 106. The first component 170 has a base portion 174 and a plurality of spring portions 176 extending therefrom in the direction of the insertion direction 106.

[0358] The spring sections 176 surround the receiving space 110 at least in sections transversely and in particular perpendicularly to the insertion direction 106.

[0359] The second component 172 can be mounted on respective ends, preferably end regions 178, of the spring sections 176 opposite the base section 174.

[0360] The spring sections 176 are movable and / or deformable, in particular reversibly and / or elastically deformable, transversely and in particular perpendicularly to the insertion direction 106 in order to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer circumference 132 of the support surface 114.

[0361] The first component 170 and the second component 172 can be detachably mounted and / or connected to one another.

[0362] The first and second components 170, 172 can be mounted and / or connected to one another in a force-locking and / or form-locking manner.

[0363] In the present case, a locking element 180 is arranged in the respective end regions 178 of the respective spring sections 176.

[0364] On an outer surface 182 of the second component 172, a corresponding groove 184 is arranged, which can be brought into engagement with the locking elements 180 for the assembly and / or connection of the first and second components 170, 172.

[0365] Furthermore, the second component 172 has a beveled and / or chamfered region 186 for easier assembly of the second component 172 to the first component 170. To insert the first component 170 into the roller 102, the spring sections 176 are moved by a user in the direction of the longitudinal axis 108 and thus inserted into the roller 102 from one side of the roller 102. Subsequently, the second component 172 is connected to the first component 170 from the other, opposite side of the roller 102 by the locking elements 180 engaging the groove 184.

[0366] This enables the support state.

[0367] In Fig. 17, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0368] The embodiment of the support device 100 shown in Fig. 17 is substantially configured and / or designed like the embodiments of the support device 100 shown in Figs. 1 to 8 and 16, so that only the differences are described below.

[0369] The base body 104 is made up of several parts, in this case two parts.

[0370] The multi-part base body 104 has two components 170, 172, here a first component 170 and a second component 172, which can be connected to one another.

[0371] The multi-part base body 104 can be disassembled and / or disassembled without destruction.

[0372] The base body 104, which can be assembled and / or composed of the components 170, 172, is circular-cylindrical in shape.

[0373] The first and second components 170, 172 can be assembled together and / or detached from each other along the insertion direction 106.

[0374] The first and second components 170, 172 are essentially cylindrical.

[0375] The first component 170 is made of an elastic material.

[0376] An interior space 188 for receiving the second component 172 is arranged and / or formed in the first component 170.

[0377] The interior space 188 tapers from one end 190 of the first component 170 to the other end 192 of the first component 170, for example, with an inclination of 1° to 5°, e.g., 2°. The support surface 114 is arranged on an outer side of the first component 170 facing away from the interior space 188.

[0378] The second component 172 is complementary to the first component 170 and / or designed as a corresponding counter-component.

[0379] The second component 172 is made of a non-elastic and / or rigid material.

[0380] The receiving space 110 is arranged and / or formed in the second component 172.

[0381] An outer side of the second component 172 facing away from the receiving space 110 is inclined from one end 194 of the second component 172 to the other end 196 of the second component 172, preferably with an inclination corresponding to the said inclination of the first component 170.

[0382] A minimum outer diameter of the second component 172 is smaller than a maximum inner diameter of the first component 170, whereby the second component 172 can be inserted into the interior 188 of the first component 170.

[0383] This serves in particular to enlarge the outer diameter of the first component 170 so that it can be converted into the said effective outer diameter 132.

[0384] By inserting the second component 172 into the interior space 188 of the first component 170, the first component 170 is elastically deformable or is deformed in order to be convertible into the support state and / or to be converted into the support state.

[0385] In a sense, first the first component 170 is insertable and / or is inserted into the roller 102 and then the second component 172 is insertable and / or is inserted into the first component 170 to enable the said support state.

[0386] In Figs. 18 and 19, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0387] The embodiment of the support device 100 shown in Figs. 18 and 19 is essentially configured and / or designed like the embodiment of the support device 100 shown in Figs. 4 to 6, so that only the differences are described below. The base body 104 has three sections 124, 126, 128 and three joint devices 134, 136, 146. In the present embodiment, all joint devices 134, 136, 146 are arranged and / or formed on the outside, i.e., on the outer side 116, relative to the receiving space 110.

[0388] The first, second and third joint devices 134, 136, 146 are of identical design.

[0389] In particular, all joint devices 134, 136, 146 have the same opening angle.

[0390] The opening angle is preferably approximately 120° ± 20% or approximately 120° ± 10% or approximately 120° ± 5%.

[0391] The joint devices 134, 136, 146 or the respective grooves 144 have a concave cross-section.

[0392] As can be seen in Figs. 18 and 19, outwardly facing edge regions of a respective groove 144 are rounded.

[0393] A ratio between the wall thickness and the wall thickness reduced section forming the groove 144 may preferably be between 10 to 1 and 2 to 1, for example approximately 3 to 1.

[0394] The first section 124 is movable inwardly via the first joint device 134.

[0395] The third section 128 is movable inwardly via the second joint device 136.

[0396] The third joint device 146 is movable inwardly and / or in the direction of the second section 126 via an inward movement of the first and / or the third section 124, 128.

[0397] In the reduced-volume and / or outer-periphery state, the base body 104 has a substantially heart-shaped contour 140. To a certain extent, the base body 104 can be folded and / or moved together and / or deformed in a heart shape to reduce the volume 130 of the receiving space 110 and / or to reduce the effective outer periphery 132 of the support surface 114.

[0398] In particular, the support device 100 can be inserted into the roller 102 in this state.

[0399] Optionally, it can be provided that an edge 198 of the base body 104 arranged on the outside and / or on the front side, which edge is located in an end region and / or at one end of the base body 104, is bevelled and / or chamfered, whereby the support device 100 can advantageously be inserted into the roller 102 more easily and / or smoothly.

[0400] In Figs. 20 and 21, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0401] The embodiment of the support device 100 shown in Figs. 20 and 21 is substantially configured and / or designed like the embodiment of the support device 100 shown in Figs. 18 and 19, so that only the differences are described below.

[0402] As can be seen in the respective figures, the said support devices 100 differ in that in the support device 100 of Fig. 20 and 21, a distance between the first and the second joint device 134, 136 is approximately 135° and a respective distance of the third joint device 146 with respect to the first and the second joint device 134, 136 is approximately 67.5°, whereas in the support device 100 of Fig. 19 and 20, a distance between the first and the second joint device 134, 136 is approximately 180° and a respective distance of the third joint device 146 with respect to the first and the second joint device 134, 136 is approximately 90°.

[0403] In Figs. 22 and 23, a support device 100 for a roll 102 of web-shaped material, in particular toilet paper, according to a further embodiment of the present invention is shown schematically.

[0404] The embodiment of the support device 100 shown in Figs. 22 and 23 is essentially configured and / or designed like the embodiment of the support device 100 shown in Figs. 18 and 19, so that only the differences are described below. As can be seen from the figures, the support device 100 has a fourth joint device 200.

[0405] The fourth joint device 200 is arranged between the first and second joint devices 134, 136 and opposite the third joint device 146.

[0406] Accordingly, the base body 104 has four sections 124, 126, 128, 160.

[0407] The first joint device 134 is arranged between the first and second sections 124, 126.

[0408] The second joint device 136 is arranged between the fourth and third sections 160, 128.

[0409] The third joint device 146 is arranged between the third and the first section 128, 124.

[0410] The fourth joint device 200 is arranged between the fourth and the second section 160, 126.

[0411] All joint devices 134, 136, 146, 200 are arranged and / or formed on the outside, i.e. on the outer side 116, relative to the receiving space 110.

[0412] The first, second, third and fourth joint devices 134, 136, 146, 200 are of identical design.

[0413] The four joint devices 134, 136, 146, 200 are arranged and / or formed at equal distances from one another, in the present case spaced apart by 90° from one another.

[0414] The third and fourth joint devices 146, 200 are arranged opposite each other and spaced apart by 180°.

[0415] The first and second joint devices 134, 136 are arranged opposite one another and spaced 180° apart.
