Description

[0001] Title: Bag for mounting to a foldable wheeled walker, foldable wheeled walker

[0002] The invention relates to a bag for mounting to a foldable wheeled walker, a foldable wheeled walker comprising said bag and a method of safely storing times in such a bag mounted to a foldable wheeled walker.

[0003] A wheeled walker, or a rollator, is a mobility aid for assisting individuals who have difficulty walking or maintaining balance, e.g. senior citizens. Commonly, a wheeled walker has a frame, e.g. a lightweight frame, with four wheels attached to the frame, handlebars for support and a seat for resting. Wheeled walkers are used to enhance mobility, increase independence of the user, and / or reduce the risk of falling for elderly people or those with physical disabilities.

[0004] A wheeled walker may be foldable, such that the frame of the wheeled walker has a mechanism that allows it to be folded into a compact size. A folded wheeled walker can be stored in relatively small spaces such as car trunks or in closets. A disadvantage of a foldable wheeled walker is that the folding mechanism can be a safety hazard for a user, in particular when folding the foldable wheeled walker. A person folding the foldable wheeled walker may get a body part, e.g. a finger, stuck between the folding mechanism.

[0005] Foldable wheeled walkers, and wheeled walkers in general, often have storage features in order to enhance convenience for its users. These often comprise a storage basket or pouch located in front of and attached to the frame. The storage space can hold items such as personal items, groceries, medical supplies etc., and allows the user to carry items handsfree such that they can hold the handlebars of the wheeled walker. A disadvantage of commonly available storage features for foldable wheeled walkers is that the storage features need to be removed from the foldable wheeled walker before the foldable wheeled walker can be folded and stored. Removing the storage features may be difficult for users of a foldable wheeled walker, and thus may be a cumbersome task. In addition, for wheeled walkers in general, the position of the storage features may cause the combined center of gravity of the wheeled walker, the storage features and items stored in the storage feature to shift forward compared to a wheeled walker without items provided in the storage features, or without storage features. As a result, storing items in the storage feature of the wheeled walker may result in imbalance and / or instability of the wheeled walker and may impact the safety of the user of the wheeled walker.

[0006] The invention aims to counteract the above disadvantages, preferably while retaining the advantages. More specifically, the invention aims to provide for a more safe storage of items to the wheeled walker. The invention may therefore aim for a bag for a foldable wheeled walker that improves the safety of a foldable wheeled walker, while improving ease of use and keeping or even improving the storage capacity available.

[0007] Therefore, the invention provides a bag for mounting to a foldable wheeled walker, in particular a bag for mounting to a foldable wheeled walker according to claim 1. The bag comprises a first bag part having a first rear side arranged to face a first side of a folding arrangement of the wheeled walker and a second bag part having a second rear side arranged to face a second side of the folding arrangement. At least one of the first bag part and the second bag part comprise a receiving volume for receiving items therein. The first bag part and the second bag part are foldable in a direction that is in a plane of the first rear side and the second rear side respectively.

[0008] The first bag part and the second bag part are provided with a respective first rear side and second rear that is arranged to face the first side and the second side respectively of the folding arrangement of the foldable wheeled walker. Since the first side of the folding arrangement and the second side of the folding arrangement are opposite each other, with the folding arrangement in between, the first rear side and the second rear side of the bag are facing each other. By providing the respective bag parts with respective rear sides that are facing each other, the folding arrangement of the wheeled walker can be received between the respective rear sides of the bag parts. As such, in use, when the bag is mounted to the wheeled walker, the folding arrangement is covered. Covering the folding arrangement may increase safety when using a foldable wheeled walker to which the bag is mounted, in particular when folding the foldable wheeled walker. Once the folding arrangement is covered, it may be less likely that a person folding the wheeled walker may accidently have a body part, e.g. a finger, stuck between the folding arrangement. Preferably, the first bag part and the second bag part are arranged to cover the first and second side of the folding arrangement in its entirety, e.g. by covering a surface equal or larger than a surface of the first side and a surface of the second side. By covering the first and the second side of the folding arrangement, preferably in its entirety, the folding arrangement can be concealed from view and from contact, thereby enhancing safety of use of the wheeled walker.

[0009] The receiving volume may be formed such that it covers the folding arrangement, e.g. by having one of the walls defining the receiving volume being a rear side corresponding to the bag part that has a receiving volume. The receiving volume may be defined by additional wall elements, e.g. four additional wall elements of which one acts as a floor element, thus forming a box or trapezoid shaped receiving volume. Other numbers of additional wall elements may be provided, e.g. two additional wall elements of which one acts as a floor element, forming an elliptically shaped receiving volume. The receiving volume may have an access opening, allowing users to access the receiving volume for putting items therein. The opening can remain uncovered or may be covered by a lid or flap to cover said opening and thus closing receiving volume. This may be useful in order to prevent unwanted access to the receiving volume or to protect products stored in the receiving volume to external influences such as the weather. Preferably, the access opening extends in a direction away from the respective rear side of the respective bag part comprising the said receiving volume. The access opening thus may extend in a direction away from the respective rear sides towards a front side of the respective bag parts. This allows easy access to the receiving volume, and, when the bag is mounted to the wheeled walker, without interference with the folding arrangement.

[0010] The bag may be arranged to be foldable. Then, when folding the wheeled walker, the bag can remain mounted to the wheeled walker and can be folded together with the wheeled walker. This further enhances the safety of use of the wheeled walker, as the folding arrangement can remain covered during folding also, thereby obviating that users may interfere with the folding arrangement, preventing possible injuries. Preferably, the bag is foldable in a folding direction in a plane of the first rear side and the second rear side. By providing the first bag part and the second bag part such that they are foldable in the folding direction, in a plane of the first rear side and the second rear side respectively, it may be possible for the bag to fold in the same direction as the wheeled walker folds during use. This may further improve convenience when folding the wheeled walker, as it may be possible to fold the wheeled walker and the bag in one action.

[0011] The bag can be foldable by making the bag, in particular the bag parts, of a foldable material, e.g. fabric, or by making the bag out of a mix of rigid material, e.g. plastic, interspaced with a foldable material. A foldable bag may facilitate that the bag can be folded before or during folding the wheeled walker. Thus, it is not necessary to unmount the bag from the foldable wheeled walker, when the wheeled walker is folded. This significantly reduces the steps needed for folding and storing a wheeled walker, and subsequently retrieving the wheeled walker and unfolding, as all the steps related to removing and mounting the bag are no longer needed. The receiving volume, which can be comprised by the first bag part and / or by the second bag part, is thus also foldable in the plane of the respective rear side.

[0012] It will be understood by the skilled person that ‘foldable in a folding direction in a plane’ should be understood as folding in a direction that lies within or is parallel to the plane of the rear side of the bag parts. Also, folding direction refers to the direction in which the bag is folded. When the bag, in use, is mounted to the wheeled walker the direction in which the bag is folded is the same direction in which the wheeled walker is folded, so that the folding direction of the bag is the same as the folding direction of the wheeled walker. In other words the folding direction is the direction of the folding movement of the bag and this direction is in the plane of the respective rear side of the bag, as opposed to being transverse or perpendicular to such a plane. This does not exclude that parts of the bag during folding or after folding extend in any other direction than the direction of the folding movement. For example, if the rear side of the bag in unfolded condition extends in a plane, and this plane spans an imaginary X- Y plane, the first bag part and the second bag part are foldable in a direction that lies within or is parallel to the X-Y plane, e.g. in the X-direction, in the Y-direction or a combination of both directions. It should be noted that, when folding, components of the first bag part and / or second bag part may deform in any direction including a direction not being the folding direction. For example, if the first bag part and the second bag part are foldable in the plane in a pleated fashion, the folds formed may extend in a direction transverse to the plane. It is also understood that the rear side of the bag part extending in a plane means that the rear side of the bag part is, in unfolded position, plate-like without necessarily having the rigidity and / or the stiffness of a plate, as it needs to be foldable towards a folded position as well.

[0013] For example, a wheeled walker comprising two side frames with the folding arrangement in between may be folded by moving the side frames towards each other. The folding direction can then be said to be the direction in which the two side frames are moved towards each other. The bag mounted to the folding arrangement folds together with the folding arrangement and becomes confined between the side frames. Here, the folding direction may be understood to be substantially horizontally and transverse to the side frames, wherein the folding direction of the folding arrangement is the same as the folding direction of the bag. Alternatively, the side frames may be foldable in itself by moving an upper part of the side frames towards a lower part of the side frames. The folding arrangement may then be a hinged arrangement in the side frames. The bag mounted to the wheeled walker may then fold together with the side frames and may become confined between the upper part and the lower part of the side frames. Here, the folding direction may be understood to be substantially vertically.

[0014] The first rear side of the first bag part has a first width and a first height, and the second rear side of the second bag part has a second width and a second height. The bag is foldable between an unfolded position and folded position. In the unfolded position the first and second rear sides extend respectively over the first and second height and over the first and second width. The respective rear sides are thus unfolded as well. In the folded position, the rear sides have been folded in a direction of folding towards a position in which the rear sides have a width smaller than their respective width in the unfolded position. In the folded position, the height of the respective rear sides remains the same as in the unfolded position.

[0015] The first bag part and the second bag part may comprise a first front side and a second front side opposite the first rear side and the second rear of the corresponding bag part. Similar to the first rear side and the second rear side, said first rear side and second rear side may extend respectively over the third and fourth height and over the third and fourth width. The third and fourth height may be substantially the same as the first and second height, the third and fourth width may be substantially the same as the first and second width. In the unfolded position the first and second front sides extend respectively over the third and fourth height and over the third and fourth width. The respective front sides are thus unfolded as well. In the folded position, the front sides have been folded in a direction of folding towards a position in which the rear sides have a width smaller than their respective width in the unfolded position. In the folded position, the height of the respective rear sides remains the same as in the unfolded position.

[0016] The first bag part and / or the second bag part may comprise a stiffening structure, that is adjustable between an expanded position, arranged to provide some stiffness to the respective bag part, and a folded position, wherein the stiffening structure is folded to allow the bag parts to fold in the folding direction. The provided stiffness in the expanded position may assist in keeping the bag part in a predefined shape. For example, if the bag part does not comprise a receiving volume and may be provided to cover the folding arrangement, the stiffening structure may facilitate that the corresponding bag part remains in place under external effects, such as wind or a user accidentally exerting a force on the bag. If the bag part comprises a receiving volume, the stiffening structure may span the receiving volume such that the bag part may not sag and the receiving volume may easily be accessed.

[0017] In the folded position, and when transitioning between the expanded position and the folded position, the stiffening structure may cause the bag part to fold in the folding direction while ensuring that sections of the bag part that may move in a direction transverse to the folding direction, do not become lodged or stuck between the folding arrangement of the wheeled walker. For example, the stiffening structure may cause the corresponding bag part, when folded in the folding direction, to cause the folds that move in a direction transverse to the folding direction to move away from the folding arrangement. Thereby, the bag parts may be kept free from the folding arrangement, and it may be prevented that the bag parts, or the rear sides thereof, become stuck to the folding arrangement.

[0018] Examples of stiffening structures may be plates of plastic material, that are elastically deformable by a user but biased towards a certain shape or a structure based on baleen. Another example may be a framework or skeleton structure that in folded position projects away from the folding arrangement to prevent engagement of the bag parts, in particular of the rear sides of the bag parts with the folding arrangement. Another example may be a stiffening structure as a scissor folding structure, such scissor folding structure may be foldable in the folding direction without projections. Alternatively, harmonica like stiffening structures may be envisaged.

[0019] Additionally or alternatively to the stiffening structure the first bag part and I or the second bag part may comprise a pair of side panels. Each side panel of the pair of side panels is provided on opposite sides of the corresponding bag part and each side panel of the pair of side panels faces in the folding direction. Each panel of the pair of side panels is a shaperetaining side panel such that each side panel is arranged to have substantially the same shape when the bag is in the folded position and the unfolded position. In the context of the invention, shape-retaining should be understood as being able to have substantially the same shape in both the folded position and unfolded position, and optionally when moving from one position to the other. This may be facilitated by providing a rigid side panel, that is sufficiently rigid such that it does not deform in the folded or unfolded position or by providing a panel that is elastically deformable such that it is biased towards its original shape. In other words the panel returns to it’s original shape after an external force applied to panel, elastically deforming said panel, is removed. The shape-retaining property of the panel may be provided by providing the whole panel of a rigid or elastically deformable material or by providing a section of the panel as a rigid or elastically deformable, e.g. a frame provided on the outer edges of said panel and a non- shape retaining material in between such as cloth. While the other sides of the bag part may change shape, and be reduced over at least one dimension such as its width, by folding the shape retaining side panels do not have this property and are not folded or foldable during normal use of the bag. Shape-retaining side panels may provide similar advantages as the stiffening structure for example, but not, limited to keeping the bag parts free from the folding arrangement, facilitate keeping the bag parts in place, etc.

[0020] The side panels are arranged to be releasably connected to the foldable wheeled walker, such that when the foldable wheeled walker is moved from a walking position to a folded position, the folding arrangement remains covered by the bag parts and the bag parts do not become lodged or stuck between the folding arrangement. This may be facilitated by providing the first bag part and I or second bag part that comprises a biasing element arranged to be releasably attached to a foldable wheeled walker. The biasing element may be provided towards a top or a bottom of the corresponding bag part. To conveniently attach the biasing element to the foldable wheeled walker, a biasing connector may be provided on the wheeled walker. As an example, the biasing element may be provided as a elastic loop and the biasing connector may be provided as a hook-shaped element. The elastic loop may be attached to the hook such that the elastic loop is biased keeps the corresponding bag part such that it keeps covering the folding arrangement, both in the unfolded and folded position and preferably when moving from one said positions to the other.

[0021] Both the first bag part and the second bag part can comprise a receiving volume for receiving items therein. The receiving volumes can both have different volumes, e.g. the receiving volume of the second bag part may be larger than the first bag part or vice versa. Providing a receiving volume for both bag parts may increase the volume that may be carried in the bag, as well as may improve stability of the wheeled walker during use. Instead of carrying the items at the front of the wheeled walker, as is the situation with the prior art walkers, the load of the items to be carried can now be distributed at a front side and at a rear side of the wheeled walker. This may improve the stability of the wheeled walker with load.

[0022] Advantageously, a projection of the combined center of gravity of the loads in the bag parts onto the support plane as defined by the wheels of the wheeled walker, preferably is at or near the center of the support plane. As such, the loads in the bag may not or only limited contribute to an overturning moment. Advantageously, the projection onto the support plane of the combined center of gravity of the wheeled walker, the bag and the contents of the bag may be provided towards the middle between front wheels and rear wheels of the foldable wheeled walker, thereby limiting or reducing a possible overturning moment caused by the contents in the bag. In a preferred embodiment the receiving volume is provided at the side of the folding arrangement facing, in use, the rear of the wheeled walker, causing the combined center of gravity of the wheeled walker, the bag and the contents of the bag provided to be closer to a center of the support plane defined by the wheels of the walker. This may allow for a more safe operation of the wheeled walker, as it is less likely that when the wheeled walker hits an obstacle when moving in a moving direction the wheeled walker topples over.

[0023] The receiving volume of the first and / or second bag part can be closable by a flap element. The flap element can at least partially cover an opening of the corresponding receiving volume. This may protect the products provided in the receiving volume during use, against persons, animals and / or weather elements. It may also prevent the products from falling out of the receiving volume. A flap element may be provided for each receiving volume individually, such that a corresponding flap may individually close the receiving volume, or a single flap element may be provided for covering both receiving volumes, if both the first and second bag part comprise a receiving volume. Additionally and / or alternatively, each flap element may comprise of a plurality of flap sections, each arranged to partially close the corresponding receiving volume. Additionally and / or alternatively, the flap element can be provided on a side opposite the first rear side of the associated bag part. Such a flap element may open a side of the corresponding bag part that defines the receiving volume. This may provide a larger access opening, facilitating easier access to the receiving volume. The flap element may be made of a stiff material or a foldable material. Additionally or alternatively, the flap element may comprise stiffening elements in order to facilitate a predefined shape, e.g. a shape corresponding to the opening and / or to facilitate folding of the bag part, or may be provided without stiffening elements.

[0024] The bag can further comprise a seat section arranged to be substantially horizontal during use. The seat section can be used by the user of the foldable wheeled walker to sit on, e.g. to take a rest, when using the foldable wheeled walker. In a special embodiment, the seat section can act as a lid, or foldable flap for closing the receiving volume of the corresponding bag parts.

[0025] The bag can further comprise a bridging section arranged to connect the first bag part and the second bag part. Preferably, the bridging section can be arranged to be, in use, positioned above the folding arrangement of the wheeled walker. As such, the bag including the bridging section can be mounted over the folding arrangement, while the bridging section is above the folding arrangement and both bag parts are at each side of the bridging section. Such a bridging section may further improve stability of the foldable wheeled walker to which the bag is attached during use, and may further reduce the risk of the bag becoming unmounted from the foldable wheeled walker by accident, e.g. due to unwanted external impact such as bumping in to an obstacle.

[0026] The bridging section can be configured to comprise at least one of the flap element and the seat section. In other words, the flap element and / or the seat section may be integrated into the bridging section. Forming an integrated component may reduce the total size relative to the separately produced and combined components. For example, the flap elements may be integrated in the bridging section. Said bridging section may then comprise e.g. hinging elements to move the flap elements out of the opening of the corresponding bag part, in order to provide access to the receiving volume. Moreover, providing an integrated component of the bridging section, the flap element and the seating section may provide for more ease of use of the wheeled walker. Such integrated component may be sufficiently strong and stiff to function as a seat section and to be used as a seat by the user. The respective bag parts of the bag may be connected to the integrated component, thereby allowing it to function as the bridging section. Further, part of the integrated component may be adjustable to open and close the receiving volume of the respective bag part. Such integrated component may further enhance a compact design of the bag.

[0027] The bridging section and / or the seat section and / or the flap element can be foldable in the folding direction, such that they can be folded together with the bag parts and / or the folding arrangement of the wheeled walker. In an example, these components are present and foldable in the folding direction. Thus, the bag with the bridging section, the first bag part, the second bag part, the seat section and the flap element can be foldable in the direction of folding of the folding arrangement of the foldable wheeled walker such that the bag may not be removed from the foldable wheeled walker when the foldable wheeled walker is folded. In case the bridging section and / or the seat section and / or the flap element may be integrated in an integrated component, the integrated component may be foldable in the folding direction to follow the folding of the bag parts and / or of the folding arrangement.

[0028] The bag can comprise attachment elements arranged to releasably attach at least two of the first bag part, the second bag part, the flap element, the bridging section and the seat section to each other. The first bag part and the second bag part can be releasably attached to each other via attachment elements provided on the first bag part and the second bag part. Thus, the bag parts may be separated from each other. This may be advantageous in case a user wants to disconnect one bag part, e.g. the first bag part, while keeping the other bag part, e.g. the second bag part mounted to the foldable wheeled walker, for example because the first bag part is filled with products in a receiving space. These attachment elements may be provided as a zipper connection, such that the bag parts can be separated by opening the zipper. However, it will be understood that alternative attachment elements may be provided, such as magnets, wires, click fingers and / or buttons. The first bag part and the second bag part can be releasably connected to the bridging section. This may allow for the bag parts to be individually removed from the bridging section, such that the bag parts can be used separately, e.g. as a carrier when the corresponding bag part has a receiving volume. Furthermore, this may allow for the user of the bag to customize the bag to closely fit the intended purpose. For example, if only a limited amount of products is stored in the receiving volume, e.g. such that they can be provided in a single receiving volume, only one bag part can be disconnected from the bridging section and from the other bag part. The first and second bag part may be releasably connected to the bridging section by various commonly known connection elements, such as zips, studs, hooks, etc. Alternatively, instead of the releasable connection between the various components of the bag, the bag parts and / or the bridging section and / or the flap elements may be fixedly connected to each other as to form a single piece. The bag can comprise a mounting arrangement for mounting the bag to the wheeled walker. This may facilitate a firm and / or reliable connection of the bag to the foldable wheeled walker during use. It may also allow for the bag to be mounted to the wheeled walker in an effective manner, even if the part of the wheeled walker it is attached to is slanted, e.g. provided under an acute angle relative to the horizon. Various components of the bag may be provided with mounting element of the mounting arrangement, e.g. the first bag part and the second bag part may each be provided with mounting elements to mount to the wheeled walker. Alternatively and / or additionally, when a bridging section is present, such bridging section may be provided with mounting elements, e.g. while the respective bag parts may be attached to the bridging section with the aforementioned attachment elements.

[0029] In a second aspect of the invention, a set of a foldable wheeled walker and a bag is provided. The set comprises a foldable wheeled walker and a bag as described above, the foldable wheeled walker having a first side frame and a second side frame connected by a folding arrangement such that the foldable wheeled walker has a walking position in which the first and second side frames are at a distance from each other with the folding arrangement in an unfolded position therebetween and a folded position in which the first and second side frames are adjacent to each other with the folding arrangement in a folded position therebetween. The foldable wheeled walker further comprises a pair of wheels provided on the first side frame and a pair of wheels provided on the second side frame such that a first wheel of the pair of wheels is provided towards the front of the corresponding side frame and a second wheel of the pair of wheels is provided towards the rear of the corresponding side frame. Thus, when the foldable wheeled walker is folded, the side frames of the foldable wheeled walker are moved towards each other, namely in the folding direction. When the wheeled walker is in the walking position and the folding arrangement in the unfolded position, the side frames are at a distance from each other, which distance allows a person to stand behind or to stand in between the side frames such that the person can move the wheeled walker. In the folded position of the folding arrangement, the side frames of the wheeled walker are moved towards each other such that the distance between the side frames is smaller than in the unfolded position of the folding arrangement. The wheeled walker is in a storage position when the folding arrangement is in folded position. The bag provided folds in the same folding direction, such that the bag with the bag parts can remain on the foldable wheeled walker during folding and in the folded position. Preferably, the bag may not hinder the folding of the foldable wheeled walker, e.g. by getting lodged in the folding arrangement. The foldable wheeled walker may be a commonly available foldable wheeled walker.

[0030] In order to facilitate mounting of the bag to the wheeled walker, the mounting arrangement of the bag can comprise first mounting elements for mounting the bag to the foldable wheeled walker. The first mounting elements may comprise for example a physical connector, e.g. a hook, a rail, a pen, a clip, a strap, etc., to mount the bag part to the foldable wheeled walker. As an alternative, the first mounting elements my comprise magnets for forming a magnetic connection between the corresponding bag part and the foldable wheeled walker. If the foldable wheeled walker is made of a magnetizable material, magnets may only be needed to be provided on the bag part to allow the bag to be mounted to the foldable wheeled walker.

[0031] The first mounting elements can be for example provided in the bridging element, allowing the first and / or second bag part to hang from the bridging element, when said bridging element is attached to the foldable wheeled walker. Additionally, further first mounting elements can be provided, attaching the first and / or second bag part to each other and / or to the foldable wheeled walker or mounting the seat section to the walker etc. Additionally, the foldable wheeled walker can further comprise second mounting elements for cooperating with the first mounting elements of the bag. In case the first mounting elements comprise a physical connector, it may be advantageous to provide corresponding physical connectors on the foldable wheeled walker, e.g. second mounting elements, that allows the physical connector on the bag to interface with the foldable wheeled walker. The second mounting elements can be already part of the foldable wheeled walker, e.g. by using existing features of the wheeled walker which may or may not be originally intended for such purpose. For example, the side frames of the wheeled walker may comprise openings that may act as second mounting elements. Alternatively, auxiliary components may be provided that can act as mounting elements. Additionally and / or alternatively, the second mounting elements may be provided to the folding arrangement.

[0032] The first mounting elements can comprise a pivot element, and the second mounting elements can comprise a receiving element for cooperation with the pivot element. The pivot and receiving elements are arranged for pivotably mounting the bag to the foldable wheeled walker. A pivot element may be an axle provided towards the bottom of the first and / or second bag part. The axle may be provided parallel to the plane of the first and / or second rear side respectively. A receiving element may be a bracket for receiving such axle. When the bag is mounted to the foldable wheeled walker, a user may first pivotably mount the first or second bag part to corresponding mounting elements on the foldable wheeled walker. Next, the bag may be pivoted, via the pivot element, for example over the folding arrangement of the foldable wheeled walker. Once pivoted over the folding arrangement, the other bag part may be mounted to the foldable wheeled walker. Using a pivot element for mounting, the bag may be mounted to the foldable wheeled walker by rotationally locking as opposed to other connection methods such as snap fitting. This may be advantageous, as mounting / unmounting by rotating the bag over the folding arrangement may require less strength of a user, e.g. compared to mounting the bag compared to snap fitting.

[0033] The bag part of the bag comprising the receiving volume can be mounted at a rear side of the foldable wheeled walker, seen in walking direction. In the specific embodiment, the combined center of gravity of the wheeled walker, the bag and the items provided in the receiving volume may be centered between the wheels, which may facilitate stability of the wheeled walker during use, e.g. when accidentally bumping into obstacles. Thereby, safety of the wheeled walker may be even further improved. Advantageously, a projection, on the support plane defined by the wheels of the wheeled walker, of the center of gravity of the items loaded in the bag is near or adjacent the center of the support plane, which may enhance stability of the wheeled walker when loaded.

[0034] The stiffening structure of the bag can be arranged to, when the stiffening structure is folded to allow the bag parts to fold transverse to the folding direction in the plane of the respective rear sides. When the bag parts fold away from the folding arrangement, risk of the bag parts getting lodged in the folding arrangement can be even further reduced.

[0035] In a third aspect of the invention, there is provided for a foldable wheeled walker. The wheeled walker comprises: a first side frame and a second side frame connected by a folding arrangement such that the foldable wheeled walker has a walking position in which the first and second side frames are at a distance from each other with the folding arrangement in an unfolded position therebetween and a folded position in which the first and second side frames are adjacent to each other with the folding arrangement in a folded position therebetween; and a pair of wheels provided on the first side frame and on the second side frame such that a first wheel of the pair of wheels is provided towards a front of the corresponding side frame and a second wheel of the pair of wheels is provided towards a rear of the corresponding side frame, seen in walking direction; the four wheels of the two pairs of wheels defining a support plane; wherein the wheeled walker is provided with a receiving volume of a bag for receiving items defining a load therein, wherein the receiving volume is arranged to the wheeled walker such that a projected position on the support plane of a center of gravity of the load, when in the receiving volume, is adjacent a center of the support plane of the wheeled walker, seen in a longitudinal direction of the wheeled walker. The receiving volume can be a receiving volume of the above defined bag.

[0036] The combined center of gravity of the foldable wheeled walker, the receiving volume and the load, when in the receiving volume, can be towards the center of the support plane. Preferably, the receiving volume can be arranged at a rear side of the folding arrangement, seen in a direction of walking. By having the center of gravity as much towards the middle of the support plane as possible, stability of the foldable wheeled walker during use is improved. Preferably, the foldable wheeled walker is designed such that a user, when using the foldable wheeled walker, is also positioned in the support plane. This may for example be achieved by spacing the handlebars sufficiently wide, such that the user may position themselves in between the handlebars, and by positioning the rear wheels of the foldable wheeled walker behind the handlebars in a direction of walking.

[0037] In a fourth aspect of the invention, there is provided for a method of safely storing items in a foldable wheeled walker. The method comprises the steps of:

[0038] - providing a foldable wheeled walker, said wheeled walker having a set of front wheels and a set of rear wheels provided towards the front of the wheeled walker and provided towards the rear of the wheeled walker in the direction of travel respectively;

[0039] - providing a bag as previously described; - mounting the bag to the foldable wheeled walker, such that at least one receiving volume is provided between the front wheels and rear wheels towards the rear wheels;

[0040] - storing items in the receiving volume such that a combined center of gravity of the foldable wheeled walker, receiving volume and items is located between the front wheels and the rear wheels, preferably halfway in between the front wheels and the rear wheels.

[0051] It is noted that the figures are only schematic representations that are given by way of non-limited examples. In the figures, the same or corresponding parts are designated with the same reference numerals.

[0052] Turning to Fig. 1A, a bag 1 for mounting to a foldable wheeled walker according to an example of the invention is shown. The bag 1 comprises a first bag part 2 having a first rear side 4 arranged to face a first side of a folding arrangement of the wheeled walker and a second bag part 3 having a second rear side 5 arranged to face a second side of a folding arrangement of the wheeled walker. At least one of the first bag part 2 and the second bag part 3 comprises a receiving volume 7 for receiving items therein, in the shown example both the first bag part 2 and the second bag part 3 comprise a receiving volume 7. The first bag part 2 and the second bag part 3 are foldable in a folding direction F in a plane A, B of the first rear side 4 and the second rear side 5 respectively. In the shown example, the plane A of the first rear side 4 and the plane B of the second rear side 5 are provided parallel to each other. In the shown example, the receiving volume 7 is defined by a plurality of wall elements and thereby forming a trapezoid shaped receiving volume 7.

[0053] In the shown example, the bag 1 comprises attachment elements 22. Specifically, the first bag part 2 and the second bag part 3 are releasably attached to each other via attachment elements 22 provided on the first bag part 2 and the second bag part 3. In the shown example, the attachment elements 22 are provided as magnets such that the bag parts 2, 3 are attached to each other when the magnets of the attachment element are provided in proximity of each other. Alternative attachment elements 22 may be used for this, e.g. zippers, buttons and click-fingers.

[0054] Turning to Figs. IB and 1C, figures are shown in which the bag 1 of Fig. 1A has been mounted to a foldable wheeled walker 10. Fig. 1C is a schematic cross-sectional view of the foldable wheeled walker 10 of Fig. IB along the C-C line. The bag 1 comprises a mounting arrangement 23 for mounting the bag 1 to the wheeled walker 10, specifically the first bag part 2 and the second bag part 3 on both sides of the folding arrangement 11. The mounting arrangement 23 comprises first mounting elements 24 for mounting the bag 1 to the foldable wheeled walker 10. The foldable wheeled walker 10 comprises second mounting elements 25 for cooperating with the first mounting elements 24 of the bag 1.

[0055] Fig. 1C gives a view on the first rear side 4 of the first bag part 2 of the bag 1 according to cross-section C-C. The first rear side 4 as a first width wl and a first height hl. By analogy, the second rear side 5 also has a height h2 and a width w2. Fig. 1C shows the first rear side 4 in unfolded position. The respective heights and widths have been indicated in the side view of Fig. IB and in top view of Fig. 2A. Fig. 2A shows the respective bag parts 2, 3 in unfolded position and Fig. 2B shows the respective bag parts 4, 5 in folded position. In the shown example, the first bag part 2 and the second bag part 3 each comprises a respective front side 40, 41, i.e. a first front side 40 and a second front side 41. The first front side 40 has a third width w3 and a third height h3, the second front side 41 has a fourth width w4 and a fourth height h4. In folded position, the respective rear sides and front sides have been folded in the direction of folding F towards the folded position in which the width of the respective front sides and rear sides are smaller than the respective widths wl, w2, w3, w4 in unfolded position. The widths of the respective rear sides in folded position is indicated by wl’,w2’, w3’ and w4’. This means that wl’ < wl , w2’ < w2, w3’ < w3 and w4’ < w4. The respective heights of the respective rear sides 4, 5 and front sides 40, 41 can remain unchanged after folding. The folding direction thus corresponds to a direction in which the width of the rear sides, and in the shown example front sides, of the bag is being decreased towards folded position or increased towards unfolded position. While the rear sides 3, 4 and the front sides 40, 41 are provided such that they are similar, it is mentioned that the front sides 40, 41 do not need to be provided such that they move in a certain direction when the bag 1 is being folded. While the rear sides 3, 4 are provided such that they remain free of the folding arrangement 11, by limiting movement of the rear sides 3, 4 towards the folding arrangement 11, such limitations are not necessary for the front sides 40, 41 as the front sides 3, 4 are provided away from the folding arrangement 11 and thus do not have the risk of becoming stuck in the folding arrangement.

[0056] The foldable wheeled walker 10 comprises a first side frame 14 and second side frame 15 connected by the folding arrangement 11. In the shown examples, the foldable wheeled walker is in a walking position. The folding arrangement 11 allows the foldable wheeled walker 10 to have a walking position, in which the first and second side frames 14, 15 are at a distance from each other, with the folding arrangement 11 in an unfolded position there between. The folding arrangement 11 allows the foldable wheeled walker 10 to be in a folded position, not depicted in Figs. IB and 1C, in which the first and second side frames 14, 15 are adjacent to each other with the folding arrangement 11 in a folded position therebetween. The foldable wheeled walker 10 further comprises a pair of wheels provided on the first side frame and on the second side frames 14, 15 such that a first wheel 16 of the pair of wheels is provided towards a front of the corresponding side frame 14, 15 and a second wheel 17 of the pair of wheels is provided towards a rear of the corresponding side frame 14, 15, seen in walking direction. In the shown example, the foldable wheeled walker comprises handlebars 33 that a user my grip when using the wheeled walker 10. In Fig. IB, it can be seen that the first rear side 4 and the second rear side 5 of the first 2 and second bag part 3 respectively face the corresponding first side 12 and second side 13 of the folding arrangement 11. In the cross-sectional view of Fig. 1C, an example of a basic folding mechanism 11 is shown. The folding mechanism 11 is a harmonic structure 11 that comprises a plurality of rods 18 that can move relative to each other such that the harmonic structure 11 can collapse in the folding direction F. This allows the side frames 14, 15 to move relative to each other, i.e. when folding the foldable wheeled walker 10. The direction of movement of the side frames 14, 15 when folding is the direction of folding F of the wheeled walker 10. In the shown example of Fig. 1C, the first bag part 2 and the second bag part (not depicted) are foldable in a direction parallel to the direction of folding F of the folding arrangement 11. This direction of folding is in the plane B of the second rear side 5 of the second bag part 3.

[0057] In Figs. 2A and 2B a schematic top view of a bag 1 mounted to a foldable wheeled walker 10 is displayed. In Fig. 2A, the foldable wheeled walker 10 is in a walking position. In the shown example, the first and second side frame 14, 15 are at a distance from each other with the folding arrangement 11 in an unfolded position therebetween. In Fig. 2B, the same foldable wheeled walker 10 is depicted, however now in a folded position. In this example, the first and second side frames 14, 15 are adjacent to each other, e.g. at a distance smaller than the distance between the first and second side frames 14, 15 in the walking position. Furthermore, the folding arrangement 11 is now in a folded position between the first and second side frame 14, 15. As can be seen, the first and second bag part 2, 3 each comprise a stiffening structure 28. The stiffening structure is adjustable between an expanded position, as shown in Fig. 2A, and a folded position as shown in Fig 2B. In the expanded position of Fig. 2A, the stiffening structure 28 provides some stiffness to the corresponding first and second bag part 2, 3. In the folded position of Fig. 2B, the stiffening structure 28 is folded such as to allow the first and second bag parts 2, 3 to fold in the folding direction F in the plane of the respective rear sides 4, 5. As can be seen when comparing Figs. 2A and 2B, the stiffening structure 28 causes the corresponding bag parts 2, 3 to move outwards, i.e. transverse to the folding direction F, away from the folding arrangement 11, when the width of the bag parts 2, 3 is reduced due to the folding of the wheeled walker 10. In other words, the stiffening structure 28 is arranged to, when in the folded position, to allow the bag parts 2, 3 to fold transverse to the folding direction F. Without such a stiffening structure 28, the one or both of the bag parts 2, 3 may fold towards the folding arrangement 11, limiting the folding of the folding arrangement 11 and preventing the bag parts 2, 3 to fold in the folding direction F in the plane A, B of the respective rear sides 4 ,5.

[0058] Turning to Figs. 3A and 3B, a bag 1 for mounting to a foldable wheeled walker 10 according to a further example has been shown. The receiving volume 7 has an access opening 34 to allow the user to access the receiving volume to put in or take out a load. The access opening 34 is substantially extending in a direction away from the rear side of the bag part of the receiving volume. For example, the first bag part 2 having a first rear side 4 is provided with a receiving volume 7 having an access opening 34. The access opening 34 is in the examples of Fig. 3A and Fig. 3B provided at an upper side of the bag part, which provides for an easy access to the receiving volume 7. Further, the access opening 34 extends in a direction D away from the respective rear side, which may be towards a front side of the respective bag part. The access opening 34 may further extend over an entire width wl, w2 of the first bag part 2 respectively second bag part 3 in unfolded position, or over a part of the width wl, w2 of the first bag part 2 respectively second bag part 3. By providing the access opening 34 in a direction away from the rear side, the user can access the receiving opening without hindering or being hindered by the folding arrangement of the walker. The access opening 34 of the first and / or second bag part 2, 3 can be closable by a flap element 8. In the example shown in Fig. 3A, the flap element 8 is provided on a top side 9 of the bag 1, and closes both openings of the receiving volume 7 of the first bag part 2 and second bag part 3 respectively. Alternatively, the flap element 8 may only partially close a receiving volume 7 of a corresponding bag part 2, 3 and / or may only be provided for one bag part 2, 3 having a receiving volume 7. In the shown example of Fig. 3A, the flap element 8 comprises a downward rib 20, which facilitates closing off the receiving volume 7. Specifically, the downward rib 20 can be attached to the corresponding bag part 2, 3, thereby preventing that the flap element 8 can open. Opposite of the downward rib 20, the flap element 8 is hingeably attached to the bag 1, such that the flap element 8 can be removed in order to access the corresponding receiving volume 7. The flap element 8 can comprise a rigid element, e.g. by making the flap element 8 completely or partially out of a rigid material, such as plastic, respectively. In the shown example of Fig. 3B, an alternative flap element 8 is depicted. The flap element 8 is arranged provided on a side opposite the rear side 21 of the associated bag part 2, 3. The flap elements 8 are hingeably connected towards the bottom of their associated bag parts 2, 3. The flap elements 8 can be releasably connected towards the top of their associated bag parts 2, 3 such that the flap elements 8 can close the receiving volume 7. The releasably connection may be formed by a physical connection, e.g. a snap fit connection, a click connection and / or a magnetic connection which may or may not be integrated to such physical connection. In the shown example, the flap elements 8 further comprise side skirts 6, forming a foldable wall between the flap element 8 and the corresponding bag part 2, 3, on both sides of the bag 1 facing towards the side frames 14, 15 of the foldable wheeled walker 10 during use. The side skirts 6 may prevent the flap element 8 from opening too far, i.e. by limiting the hinging movement. Additionally, the side skirts 6 may assist with placing products in the receiving space 7 as, without side skirts 6, the products may fall out of the corresponding bag part 2, 3.

[0059] Referring to Fig. 4A, a schematic side view of a further example of a bag 1 mounted to a foldable wheeled walker 10 is shown. In the example, the bag 1 further comprises a bridging section 26 arranged to connect the first bag part 2 and the second bag part 3. The bridging section 26 is arranged to be, in use, positioned above the folding arrangement 11 of the wheeled walker 10. The first bag part 2 and the second bag part 3 are connected to the bridging section 26. The bridging section 26 is arranged to be releasably mounted to the wheeled walker 10, such that the bridging section 26 can be removed, or unmounted, from the wheeled walker 10 when a user prefers to do so. This may for example be achieved by a snap fitting the bridging section 26 to the frame of the wheeled walker 10 or by hanging the bridging section 26 from the frame of the wheeled walker 10, e.g. using hooks. Additionally, the first bag part 2 and the second bag part 3 are also releasably connected to the bridging section 26, such that the bag parts 2, 3 can be individually disconnected from the foldable wheeled walker 10. As can be seen in the example, the bag 1 mounted to the foldable wheeled walker 10 has a seat section 27. In the shown example, the bag 1 comprises attachment elements 22 arranged to be releasably attach the first bag part 2, the second bag part 3, and the bridging section 26. The seat section 27 is provided as a seat section 27 that is releasably connectable to the bridging section 23.

[0060] Turning to Fig. 4B, a schematic cross-sectional view along the D- D line of Fig. 4A is depicted. The example bag 1 has a bridging section 26. The bridging section 26 is foldable in a direction parallel to the plane of the first rear side and the second rear side of the first bag part 2 and second bag part 3 respectively. In the shown example, the bridging section 26 is provided as an elastically deformable bridging section 26, bending outwardly when the foldable wheeled walker 10 is folded. Alternatively, this may be achieved by providing a hinge element in the bridging section 26 such that the bridging section can hinge around an axis perpendicular to the direction of folding of the foldable wheeled walker 10. In the example of Fig. 4B, the bridging section 26 is configured to comprise the seat section 27, e.g. the seat section 27 is integrated in the bridging section 26. In such a case, or when a seat section 27 is provided on the bridging section 26, the seat section 27 is preferably also foldable in a direction parallel to the folding direction F.

[0061] Figs. 5A and 5B show another example of a bag 1 for mounting to a foldable wheeled walker 10. In this example, a mounting arrangement 23 is provided in which the first mounting elements comprise a first pivot element 29 and a second pivot element 30, for pivoting the first bag part 2 and the second bag part 3 respectively relative to the foldable wheeled walker 10. In the shown example, the pivot elements 29, 30 are axles provided over the width of the corresponding bag parts 2, 3. Additionally, the wheeled walker 10 has second mounting elements comprising receiving elements 31, 32 in the form of corresponding brackets 31, 32 for receiving the pivot elements 29, 30. In the shown example, the brackets are U-shaped elements, provided at both side frames 14, 15. The opening of the U-shaped elements 31, 32 is large enough that the axles 29, 30 of the bag parts 2, 3 can be received therein. In the shown example, a bridging section 26 is provided such that the bag parts 2, 3 can be releasably connected to each other and the wheeled walker 10 towards to top. This mounting arrangement 23 is relatively easy to use, as the bag parts 2, 3 can be provided on the wheeled walker 10 and rotated such that they are locke d. It will be understood by the skilled person that such a configuration also works without a bridging section 23. In this case, the bag parts 2, 3 are attached subsequently. For example, after a first bag part 2 is attached, the bag 1 can be folded over the folding arrangement 11 and connected on the other side via a second bag part 3. In the shown example, a seat section 27 is provided. This seat section 27 is part of the wheeled walker 10, but it will be clear to the skilled person that the seat section 27 may be part of the bag 1 through the bridging section 26.

[0062] Referring to Fig. 3 A, a schematic representation of a support plane S is also shown, depicted as a dash-dotted line. As previously discussed, the wheeled walker 10 is provided with two receiving volumes 7 for receiving items (not depicted) defining a load therein. The receiving volumes 7 are arranged to the wheeled walker 10 such that a projected position on the support pane of a center of gravity G of the load is adjacent a center of the support plane S of the wheeled walker 10. The center of gravity G is represented by a dot along the support plane S. By having the center of gravity G adjacent to the middle of the support plane S, stability of the foldable wheeled walker 10 during use is improved. In the shown example, the foldable wheeled walker 10 is designed such that a user, when using the foldable wheeled walker, is also positioned in the support plane S. This is achieved by spacing the handlebars 33 sufficiently wide, such that the user may position themselves in between the handlebars, and by positioning the rear wheels 17 of both side frames 14, 15 of the foldable wheeled walker 10 behind the handlebars 33 in a direction of walking.

[0063] Turning to Fig. 6A and Fig. 6B an example of a set of a foldable wheeled walker and a bag has been depicted. Comparable to the previous examples, the foldable wheeled walker 10 comprises a first side frame 14 and second side frame 15 connected by the folding arrangement 11. In Fig. 6A and Fig. 6B the foldable wheeled walker 10 is depicted in a walking position. The folding arrangement 11 allows the foldable wheeled walker 10 to have a walking position, in which the first and second side frames 14, 15 are at a distance from each other, with the folding arrangement 11 in an unfolded position there between. The folding arrangement 11 allows the foldable wheeled walker 10 to be in a folded position, not depicted in Figs. 6A and 6B, in which the first and second side frames 14, 15 are adjacent to each other with the folding arrangement 11 in a folded position therebetween. The foldable wheeled walker 10 further comprises a pair of wheels provided on the first side frame 14 and on the second side frames 15 such that a first wheel 16 of the pair of wheels is provided towards a front of the corresponding side frame 14, 15 and a second wheel 17 of the pair of wheels is provided towards a rear of the corresponding side frame 14, 15, seen in walking direction. In the shown example, the foldable wheeled walker comprises handlebars 33 that a user my grip when using the wheeled walker 10.

[0064] Furthermore, comparable to previously depicted examples, the bag 1 of the set comprises a first bag part 2 having a first rear side 4 arranged to face a first side of a folding arrangement 11 of the wheeled walker 10 and a second bag part 3 having a second rear side 5 arranged to face a second side of a folding arrangement 11 of the wheeled walker 10. In the shown example, both the first bag part 2 and the second bag part 3 comprise a receiving volume 7 for receiving items therein. The first bag part 2 and the second bag part 3 are foldable in a folding direction F in a plane A, B of the first rear side 4 and the second rear side 5 respectively. In the shown example, the plane A of the first rear side 4 and the plane B of the second rear side 5 are provided parallel to each other. In the shown example, the receiving volume 7 is defined by a plurality of wall elements and thereby forming a trapezoid shaped receiving volume 7.

[0065] Each of the first bag part 2 and second bag part 3 in the example depicted in Figs. 6A, 6B, 7A - 7C comprises a pair of side panels 35, wherein each side panel 35 is provided on opposite sides of the corresponding bag part 2, 3, facing in a direction parallel to the folding direction F. Each side panel 35 is a shape-retaining side panel 35 such that each side panel 35 is arranged to have substantially the same shape when the bag 1 is in the folded position and in the unfolded position. In the shown example, this is achieved by providing side panels 35 that are sufficiently rigid such that, during normal use, the side panels 35 do not deform when the foldable wheeled walker is used. The bag 1 comprises a mounting arrangement 23, comprising first mounting elements 24 provided towards the top of the side panels 35. In the depicted example, the first mounting elements 24 are provided as a pair of hooks 24, each hook provided towards the top of a side panel 35. The pair of hooks 24 is arranged to cooperate with second mounting elements 25 provided on the wheeled walker 10. The second mounting elements 25 are provided as pair of horizontal rods 25. When mounting the bag 1 to the foldable wheeled walker 10, each hook 24 is snap- fitted to a corresponding rod 25 such that each bag part 2, 3 suspends from the mounting arrangement 23.

[0066] To facilitate that each bag part 2,3 remains fixed relative to the foldable wheeled walker 10, each bag part 2, 3 comprises a pair of biasing elements 38. The biasing elements 38 are arranged to be releasably connected to the foldable wheeled walker 10, in the shown example the biasing elements 38 are provided as a pair of elastically deformable loops 38. On the first side frame 14 and the second side frame 15 a pair of loop hooks 39 has been provided, the pair of loop hooks 39 being an example of a biasing connector arranged for cooperating with the biasing elements 38. Each elastically deformable loop 38 can be connected to a corresponding loop hook 39. Providing the loop hooks 39 towards the bottom of the corresponding side frame 14, 15 and towards the folding arrangement 11, it is facilitated that due to the elastic force applied by the biasing element 38 to the corresponding bag part 2, 3 that both bag part 2, 3 remain fixed relative to the foldable wheeled walker 10. In a further advantage, it biasing elements 38 and loop hooks 39 may ensure that each bag part 2, 3 covers the folding arrangement 11, increasing safety.

[0067] Referring to Figs. 7 A, 7B and 7C, various stages of folding of an foldable wheeled walker 10 have been depicted. Fig. 7A depicts the foldable wheeled walker 10 in the walking position, Fig. 7B depicts the foldable wheeled walker 10 in a semi-folded position and Fig. 7C depicts the foldable wheeled walker 10 in a folded position. Comparable to the previous examples, in the walking position, the first and second side frame 14, 15 are at a distance from each other with the folding arrangement 11 in an unfolded position therebetween as can be seen in Fig. 7 A. The same foldable wheeled walker 10 is depicted in Fig. 7C, however now in a folded position. In this example, the first and second side frames 14, 15 are adjacent to each other, e.g. at a distance smaller than the distance between the first and second side frames 14, 15 in the walking position.

[0068] Furthermore, the folding arrangement 11 is now in a folded position between the first and second side frame 14, 15. The foldable wheeled walker 10 depicted in these examples comprises a seat section 27, which is also foldable in a direction parallel to the folding direction F.

[0069] In Figs. 7A-7C, the first rear side 4 has a first width wl and a first height hl. By analogy, the second rear side 5 also has a height h2 and a width w2. In the shown example, the first bag part 2 and the second bag part 3 each comprises a respective front side 40, 41, i.e. a first front side 40 and a second front side 41. The first front side 40 has a third width w3 and a third height h3, the second front side 41 has a fourth width w4 and a fourth height h4. Fig. 7 A shows the respective bag parts 4, 5 in unfolded position and Fig. 7C shows the respective bag parts 4, 5 in folded position. In folded position, the respective rear sides and front sides have been folded in the direction of folding F towards the folded position in which the width of the respective front sides and rear sides are smaller than the respective widths wl, w2, w3, w4 in unfolded position. The widths of the respective rear sides in folded position is indicated by wl’,w2’, w3’ and w4’. This means that wl’ < wl , w2’ < w2, w3’ < w3 and w4’ < w4. The respective heights of the respective rear sides 4, 5 and front sides 40, 41 can remain unchanged after folding. The folding direction thus corresponds to a direction in which the width of the rear sides, and in the shown example front sides, of the bag is being decreased towards folded position or increased towards unfolded position. While the rear sides 3, 4 and the front sides 40, 41 are provided such that they are similar, it is mentioned that the front sides 40, 41 do not need to be provided such that they move in a certain direction when the bag

[0070] I is being folded. While the rear sides 3, 4 are provided such that they remain free of the folding arrangement 11, by limiting movement of the rear sides 3, 4 towards the folding arrangement 11, such limitations are not necessary for the front sides 40, 41 as the front sides 3, 4 are provided away from the folding arrangement 11 and thus do not have the risk of becoming stuck in the folding arrangement.

[0071] As can be seen in Figs. 7A-7C, and in Fig. 7B specifically, it can be seen that the mounting arrangement 23 together with the biasing elements 38 causes the corresponding bag parts 2, 3 correspond with the contour of the foldable wheeled walker 10. Thus, when folding or unfolding the foldable wheeled walker 10, the bag parts 2, 3 keep covering the folding arrangement

[0072] II and prevent the bag parts 2,3 from getting stuck, or pinched, between the components of the folding arrangement.

[0073] Many variations will be apparent to the skilled person in the art. Such variations are understood to be comprised within the scope of the invention as defined in the appended claims. For example, while all examples relate to a foldable wheeled walker, it will be clear to the person skilled in the art that the bag may be used for a non-foldable wheeled walker as well. Furthermore, many different methods of attaching the bag, the bag parts, and components of the bag towards a foldable wheeled walker. Only a limited amount of examples are shown, but it will be understood to the skilled person that many other combinations of the various features in the shown examples are possible as long as they are comprised within the scope of the invention as defined by the following claims.
