Description

A system for carrying a luggage item on a stroller, a recessed element, a support, a luggage item and a stroller.

FIELD OF THE INVENTION

The invention relates to a system for carrying a luggage item on a stroller.

The invention further relates to recessed element, a support, a luggage item and a stroller.

BACKGROUND OF THE INVENTION

People who carry a child in a stroller and who go for shopping in, for example, a super market have to carry the bought goods. Such persons can carry the goods in a shoulder bag. However, that is not very convenient for them because of the possible weight of the bought goods. At such moments it seems logical to use the stroller as a trolley for the bought goods. Some strollers have a basket. However, in most use cases the basket is already fdled with goods that are necessary for the child, such as clothes, nappies, etc. It is also often seen that the users start to hang a bag at a handle bar of the stroller, but this is in most cases not safe because a too heavy bag may cause the stroller to tip over or fall or the handlebar may damage if it is not able to carry the weight of the bag. Many stroller manufacturers advise the user not to put additional weight on the handle bar. Users have the same or similar problems if, for example, they want to carry goods during a daytrip or a picnic. There is a strong need to provide additional means to strollers which provide a safe way of carrying additional goods with the stroller.

For example, in published patent application W02016074015A1 an additional frame with wheels is proposed that can be attached to the handle bar and an axis of a pram or a stroller. The additional frame comprises support elements for carrying additional bags. This solution introduces quite a lot of additional elements that must be bought, stored at home and used while walking with the stroller to and from the shop. This solution is also not convenient for the user because, if the additional frame is coupled to the stroller, it is placed in the area where the user walks behind the stroller and, as such, the user has to take care not to hit the additional frame and bags with his feet.

For example, in published patent GB2497620B a sort of tow bar is added to a stroller and an additional shopping trolley can be coupled to the tow bar. This solution has the same disadvantages as the previously discussed solution of the additional frame.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a safe and convenient solution that allows carrying an additional luggage item on a stroller.

For this purpose, according to an aspect of the invention, a system for carrying a luggage item on a stroller is provided.

For this purpose, according to further aspects of the invention, a recessed element, a luggage item and a stroller are provided.

The system for carrying a luggage item on a stroller comprises a support for being arranged on a stroller and a recessed element for a luggage item. The recessed element has a top side and an opposite bottom side. If the recessed element is provided in the luggage item, the top side is in the luggage item and the bottom side forms a part of a bottom of the luggage item. The recessed element has a recess at the bottom side. The recessed element is for receiving a support surface of the support. The support is for being coupled to an axis of the stroller. The support comprising a resting element that is arranged at a position away from the axis if the support is coupled to the stroller. The resting element has the support surface for engaging with the recess of the recessed element. A shape of the recess and the support surface are selected to prevent substantial movements of the recessed element with respect to the support in a virtual plane substantially parallel to a ground if the support is coupled to the stroller and if the recessed element is placed on the support.

The system for carrying a luggage item on a stroller enables that in a very easy manner, namely, by placing the luggage item with the bottom recess on the support, the luggage item can be places on the stroller. Furthermore, because the shapes of the support surface and the recess are such that the luggage item has a relatively fixed position in the plane that is substantially parallel to the ground, the risk that the luggage item falls off is lowered and possible inconveniences of a luggage item that moves with respect to the support is prevented. Thus, the system enables a safe solution for carrying the luggage item on a stroller. Additionally, the support must be coupled to the axis, the point of gravity of the luggage item will be close to the axis and thereby the risk that the stroller collapses is reduced significantly in comparison to situation where a user hangs a bag on a handle bar of the stroller.

According to further aspects of the invention, there is provided a recessed element as defined and discussed above. According to another aspect of the invention, a luggage item is provided that comprises the recessed element that is defined and discussed above. Optionally, the luggage item is a bag.

According to an aspect of the invention, there is provided a support as defined and discussed above. According to a further aspect, a stroller is provided that comprises the support that is defined and discussed above. According to another aspect, a stroller is provided that comprises the support and the luggage item that is defined and discussed above. Optionally, the stroller may be configured such that the luggage item can tilt around an axis that substantially follows the resting element of the support up till a position where the luggage item tilts towards the seat of the stroller and where the luggage item rests to the frame of the stroller.

Further preferred embodiments of the device and method according to the invention are given in the appended claims, disclosure of which is incorporated herein by reference.

DETAILED DESCRIPTION OF EMBODIMENTS

Figure la schematically shows a first embodiment of a system 100 for carrying a luggage item on a stroller. An upper part of the figure schematically show a recessed element 110. A lower part of the figure schematically shows a support that is coupled to an axis 147 of a stroller. The axis 147 is arranged in between two wheels 148 of the stroller.

The recessed element 110 has a top side 114 and an opposite bottom side 112. In Figure la the bottom side 112 is shown and some of the side walls of the recessed element 110 can be seen. The recessed element 110 is configured to use in a luggage item (now shown separately). If the recessed element 110 is provided in the luggage item, it is arranged at the bottom side of the luggage item and then the bottom side 112 of recessed element 110 forms the bottom of the luggage item and the top side 114 is provided in the luggage item.

The recessed element 110 comprises an elongated recess 116. The elongated recess 116 is configured for receiving the support surface of the support.

The support 130 is configured for being coupled to an axis 147 of a stroller. This is schematically shown in Figure la where the support 130 has arms 136, 138 that are coupled to the axis 147. Attached to the axis 147 are two wheels 148.

The support comprises and resting element 132 that is arranged at a position away from the axis 147. This means that there is at least a predefined minimum distance between the axis 147 and the resting element 132. This predefined minimum distance is, for example, 3 cm, or 4 cm, or 5 cm or even a distance larger than 5 cm. In the example of Figure la, the resting element 132 is elongated. The resting element 132 has a support surface 134 which is, schematically seen in Figure la, a top surface of the resting element 132. In use, if the support is coupled to the axis 147, the support surface 134 is substantially facing in an upwards direction.

The shape of the elongated support surface 134 and the shape of the recess 116 are selected such that the recess 116 can receive the support surface 134 such that the recessed element 110 is supported by the support 130. Furthermore, the shape of the recess 116 and the shape of the elongated support surface 134 are selected such that, if the recessed element 110 is provided on the support 130, the recessed element has a substantially fixed position in a virtual plane parallel to the ground (assuming that the support 130 is coupled to a stroller that stands on the ground). A relatively fixed position means that very small movements in the virtual plane are possible, but that these small movements are well limited. In use it means that, if the recessed element 110 is provided in and attached to a luggage item and the luggage item is arranged on the support surface, then the luggage item cannot tilt in a direction towards one of the ends of the resting element 132. It may be that the luggage item can tilt / rotate into rotational direction around an axis that substantially follows the resting element 132. The stroller to which the support element 130 is attached may provide support such that the luggage item cannot tilt /rotate in that rotational direction any further than a predefined rotational angle.

Figure lb schematically shows a second embodiment of a system 150 for carrying a luggage item on a stroller. The system 150 comprises a support 160. In use, the support 160 is to be arranged on the stroller by, for example, coupling the support 160 with arms 136, 138 to an axis 147 of the stroller. The support 160 comprises a resting element 162 that comprises a support surface 164 that is, for example, square or rectangular. The system 150 also comprises a recessed element 151 that has a top side 154 that is, in use, inside a luggage item. The recessed element 151 has also a bottom side 152 that is opposite to the top side 154 and that may form a part of a bottom of a luggage item if the recessed element 151 is provided in a luggage item. The recessed element 151 has a recess 156 at the bottom side 152. The recess 156 has a shape such that it can receive the resting element 162 of the support and/or the support surface such that the recessed element 151 cannot move much with respect to the support 160 in a virtual plane substantially parallel to the ground (assuming that the support 160 is provided on a stroller). In particular, if the recess 156 is also square or rectangular and if the recessed element 151 is placed on top of the support 160, substantial movements of the recessed element 151 with respect to the support 160 are prevented.

Figure lc schematically shows a third embodiment of a system 170 for carrying a luggage item on a stroller. The system 170 comprises a support 180. In use, the support 180 is to be arranged on the stroller by, for example, coupling the support 180 with arms 136, 138 to an axis 147 of the stroller. The support 180 comprises resting elements 182, 182’ that comprise support surfaces 184, 184’ that are, for example, square, rectangular, circular, ellipse shaped, or the resting elements 182, 182’ are sort of pins with a small top surface. The system 170 also comprises a recessed element 171 that has a top side 174 that is, in use, inside a luggage item. The recessed element 171 has also a bottom side 172 that is opposite to the top side 174 and that may form part of a bottom of a luggage item if the recessed element 171 is provided in a luggage item. The recessed element 171 has recesses 176, 176’ at the bottom side 172. The recesses 176, 176’ have a shape such that they can receive the resting elements 182, 182’ of the support and/or the support surfaces 184, 184’ such that the recessed element 171 cannot move much with respect to the support 180 in a virtual plane substantially parallel to the ground (assuming that the support 180 is provided on a stroller). In particular, if the recesses 176, 176’ are also one of square, rectangular, circular, ellipse shaped, etc. and if the recessed element 171 is placed on top of the support 180, substantial movements of the recessed element 171 with respect to the support 180 are prevented. Also in this embodiment, it may be that the recessed element can rotate around a limited angle around an axis that substantially connects the two support surfaces 184, 184’.

The support surface 134, or the resting element 132 as a whole, may be made of a synthetic material, such as a plastic. The inner surface of the recess 116, or the recessed element 110 as a whole, may be made of a synthetic materials, such as a plastic. The resting element 132 and the recessed element 110 may be made with a molding technique, for example, an injection molding technique. In an embodiment, if the recessed element 110 (or at least the inner surface of the recess 116 ) and if the resting element 132 (or at least the support surface) are made of a synthetic material, they may be made of different synthetic materials, for example, different plastics. If two different synthetic materials are used it is prevent that if the recessed element 110 moves with respect to the resting element 132, that there is a sound, for example, a creaking sound. In general, it is not necessary that two different materials are used.

Figure 2 schematically shows the use of the system for carrying a luggage item on a stroller. At 202 it has been shown that a person carries a relatively heavy shopping bag 203 that comprises a recessed element (according to an embodiment discussed above or an embodiment that will be discussed hereinafter). At 204 it is shown that the person has a stroller 205 that comprises a support (according to an embodiment discussed above or an embodiment that will be discussed hereinafter) that is coupled to a rear axis of the stroller. The person may have to lift the bag a little bit to bring the support surface of the support in front of the recess of the recessed element. At 206 it is shown that the person may lower the bag such that the recess of the recessed element receives the support surface of the support and such that the weight of the bag is supported by the resting element of the support surface. At this point, the recessed element has, in a virtual plane parallel to the ground, a substantially fixed position. At 208 it is shown that the bag may rotate around an axis defined by the support surface towards the back side of the stroller and the back side of the stroller also provides support to the bag and prevents that the bag can further rotate. At 210 it is shown that the person can subsequently push or pull the stroller and carry the bag on the stroller while walking around with the stroller.

In Figure 2, it is shown that the recessed element may be in a bag, for example, a shopping bag 203. Embodiments are not limited to bag or shopping bags. One may also have, for example, a suitcase that has a recessed element at its bottom and the suitcase may be placed on the support that is coupled to the stroller.

In Figure 2, the bag 203 may have stiffened walls. In particular, if the bag 203 may tilt around an axis that substantially follows the resting element towards the stroller, or the frame of the stroller, then it is useful that the stiffened walls provide strength to the bag to prevent that the bag become deformed and does not have a stable position. The stiffening may be obtained by providing a sheet of foam in between two layers of fabric to form a wall of the bag. An additional advantage is that the bag is better thermally isolated if the walls comprise a sheet of foam.

Figures 3a to 3c schematically shows a fourth embodiment of a system 300 for carrying a luggage item on a stroller. In the Figures 3a to 3c a side view is presented. In Figure 3a, the system 300 comprises the recessed element 310 and the support 330. The recessed element 330 is drawn as if it is partially transparent - in practical embodiments the recessed element 330 may be made of a non-transparent material.

The recessed element 310 has a top side 314 that may be inside a luggage item if the recessed element 310 is coupled to a luggage item. The recessed element 310 has a bottom side that is opposite to the top side 314. If the recessed element 310 is provided in a luggage item, the bottom side 312 may be the bottom of the luggage item. At the bottom side 312, the recessed element 310 comprises a recess 316. The recess 316 is for receiving a support surface 334 of the support 330. An arrow with reference number 318 schematically points towards a bottom 318 of the recess 316.

The support 330 is seen in a side view. From the side of the support that is shown in Figures 3a to 3c, the resting element extends, just below the support surface 334, backwards and is arranged perpendicular to the plane of the Figures. The resting element has a surface that is the support surface 334. The support surface 334 is for resting with the recess 316 of the recessed element 310. In use, if the support 330 is coupled to a stroller, the support surface 334 is oriented in a substantial upwards direction. The support also comprises means to arrange the resting element with the support surfaces away from an axis of stroller. In the example of Figure 3a, such means are plastic arms 336 that is integrally formed with the resting element with the support surface 334. The plastic arms 336 are, in use, arranged in a direction towards an axis of a stroller. The plastic arms 336 may be long enough to extend completely to the axis and the plastic arms 336 may comprise means to couple the plastic arms to the axis. In the example of Figures 3a, the plastic arms 336 are assembled to support bars 337. In use, the support bars 337 are coupled to the axis of the stroller. In the example of Figure 3a, the support surface 334 is, seen in a side view and also seen in a cross-sectional view along a plane that is arranged perpendicular to the longitudinal direction of the resting element, slightly curved. An effect of the curved support surface 334 is that if the support surface 334 touches a surface (e.g. an inner surface of the recess 316), that there is contact between the surfaces along one or two lines and which allows a smooth tilting of the luggage item that comprises the recessed element 310.

In an embodiment, the curved support surface 334 has a cross sectional shape that matches with a cross sectional shape of the bottom 318 of the recess 316. Thereby a better contact can be made between the support 330 and the recessed element 310.

Figure 3b shows the situation wherein the recessed element 310 is placed on the support 330 and a surface of the recess of the recessed element is in contact with the support surface.

Figure 3c shows that, as indicated with arrow 399, the recessed element 310 is capable of partially rotating around a virtual axis that substantially follows the support surface. In Figure 3c it can also be seen that at a certain point the side walls of the recessed element 310 touch the plastic arms of the support 330 and thereby the rotational freedom of the recessed element around the virtual axis is limited. In line with Figure 2, this rotational freedom allows, as shown at 208, that the luggage item in which the recessed element 310 is provided may tilt towards the stroller and may be supported by the stroller.

Figure 4a schematically shows a bottom view of an embodiment of a recessed element 410. The viewing direction of Figure 4a is towards a bottom side of the recessed element. In Figure 4a two longer side edges 422, 423 of the recess are shown and two shorter side edges 420, 421 are shown. The edges are the transition between the surface that forms the bottom side and the surfaces that are the inner walls of the recess. Line 418 represents a bottom 418 of the recess, which means the portion of the recess that is furthest away from the bottom side of the recessed element 410. Elongated recess walls 426, 427 extend from one of the longer side edges 422, 423 of the recess towards the bottom 418 of the recess. The elongated recess walls 426, 427 are inwardly sloped surfaces and, thus, have an angle with respect to the bottom side of the recessed element 410. Triangular recess walls 424, 425 ach extends from one of the shorter side edges 420, 421 towards the bottom 418 of the recess -they touch the bottom 418 of the recess at a point. Triangular recess walls 424, 425 are inwardly sloped surfaces and, thus, have an angle with respect to the bottom side of the recessed element 410.

Figure 4a also schematically shows protrusions 419 that extend away from the bottom side of the recessed element 410 in an opposite direction than the inwardly oriented direction of the recess. The protrusions 419 may be used as supports if the luggage item that is provided with the recessed element stands on the ground. The protrusions 419 protect the bottom side of the recessed element against damages by the material of the ground. The protrusions also prevent, if the recessed element 410 is placed with the bottom side on a wet surface, that an airtight interface is present between the wet surface and the bottom side. Such an airtight interface would make it more difficult for the user to lift a luggage item with the recessed element from the ground.

Figure 4b schematically shows a cross-sectional view of the embodiment of the recessed element 410 of Figure 4a along line IVb-IVb’. Figure 4b shows in the cross-sectional view the protrusions 419, two comers 422, 423 that represents the two longer side edges of the recess, one corner point 418 that represents the bottom of the recess, two lines 426, 427 that are a cross-section of the elongated recess walls. Additionally, by means of dashed line 499, and also a portion of the recessed element 410 that intersects with line 499, the bottom side of the recessed element is indicated. It can be seen that the elongated recess walls 426, 427 form an angle « with respect to the bottom side 499. In an embodiment, the angle a is in a range from 10 to 60 degrees, or optionally, in a range from 20 to 50 degrees. Figure 4b also shows outer side walls 428 of the recessed element 410. Additionally, the recessed element may have internal strengthening structures such as structures 413 that couple the outer side walls 428 to the elongated recess walls 426, 427. Figure 4b further shows that the bottom 418 of the recess is not necessary a sharp line where the two elongated side walls 426, 427 touch each other. The bottom 418 of the recess may also be formed by a curved bottom surface 418’ that connects the two elongated side walls 426, 427. The curved bottom surface 418’ may follow a portion of a virtual circle that has a radius that is in the range from 40 to 120 mm, or optionally, in a range from 50 to 100 mm.

Figure 4c schematically shows a cross-sectional view of the embodiment of the recessed element 410 of Figure 4a along line IVc-IVc’. Figure 4c shows in a cross-sectional view the protrusions 419, two corners 420, 421 that represent the shorter side edges of the recess, a line 418 that represents the bottom of the recess, and two lines 424, 425 that represent the triangular recess walls. Additionally, by means of dashed line 499, and also a portion of the recessed element 410 that intersects with line 499, the bottom side of the recessed element is indicated. It can be seen that the triangular recess walls 424, 425 form an angle β with respect to the bottom side 499. In an embodiment, the angle β is in a range from 10 to 40 degrees, or optionally, in a range from 15 to 35 degrees. Figure 4c also shows outer side walls 428 of the recessed element 410 and that the recessed element 410 may have strengthening structures 413’ that are arranged in between the outer side walls 428 and the triangular recess walls 424, 425. Figure 4c further shows that the place where the triangular recess walls 424, 425 touch the bottom 418 of the recess, there may be curved transition surfaces 424’, 425’ that provide a smooth transition from the triangular recess walls 424, 425 to the bottom 418. The curved transition surfaces 424’, 425’ may substantially follow a portion of a virtual circle that has a radius in a range from 5 to 30 mm, or optionally, in a range from 10 to 25 mm.

In the embodiment of Figures 4a to 4c, the function of the elongated recess walls 426, 427 and the triangular recess walls 424, 425 is twofold. First, if the recessed element 410 is provided on the support, the walls 424 .. 427 guide the support surface of the resting element of the support towards a position near the bottom. Secondly, if the recessed element 410 is provided at the support at a relatively stable / fixed position, the walls 424 .. 427 prevent that the recess can move / fall of the support.

In the context of Figures 4a to 4c it is to be noted that, if it is assumed that the support surface has another shape, the recess of the recessed element 410 may also have another shape. For example, if the support surface is square, the recess may be square as well and the sloping surfaces may meet each other in a point at the bottom of the recess. If it is assumed that the resting element of the support is a pin with a relatively small (supporting) top surface, then the recess may be square and the sloping surfaces may meet each other in a point at the bottom of the recess. If the resting element of the support is the pin with the relatively small (supporting) top surface, then the recess may also have a circular cross-sectional shape at the bottom side of the recessed element, and the inner surface of the recess may have the conical shape, or the shape of a truncated cone.

With respect to the above provided discussion of the recessed element 410, it is to be noted that, in general, the recessed element does not necessary have the side walls 428 that extend from the front side towards the back side of the recessed element.

Embodiments of the recessed element may have side walls 428 that are less high, or in other embodiments, the recessed element may lack the side walls 428. Additionally, the recessed element does not necessary have the (strengthening) structures 413.

Figure 5a schematically shows a three dimensional view of a bag 500 that is suitable for being assembled with a recessed element. The presented bag 500 has a top side 502 that comprises an opening that can be used to put good in the bag 500 and may comprise handles to carry the bag 500. Opposite to the top side 502 is the bottom side 504 of the bag.

In normal use, the bottom side 504 faces the ground and, for example, if the bag 500 is put on the ground, the bottom side 504 is closest to the ground. The bag 500 has side surface 506, 506’. As discussed earlier, the side surfaces 506, 506’ may be stiffened such that the bag 500 maintains its shape, even if the bag 500 is loaded with good. The stiffening may be obtained by providing relatively stiff sheets in the walls of the bag 500 - this may be obtained by providing a sheet of plastic in the walls. In another embodiment, foam sheets may be provided in between two fabric layers to stiffen the walls of the bag 500. The foam sheets have an additional advantage of providing a space in the bag that is relatively well thermally isolated with respect to the surroundings of the bag 500. One or a few of the side surfaces 506’ may also comprise an additional strap 508 that is partially coupled to the side surface 506’ by means of, for example, velcro. The additional straps 508 may be used to fasten the bag 500 to a bar of a frame of a stroller.

Figure 5b schematically shows a three dimensional view a bottom side of the bag 500 that is suitable for being assembled with a recessed element. Figure 5b shows the side surface 506, 506’, the additional strap 508 and the bottom side 504 of the bag 500. At the bottom side is created an opening 509 in the fabric. The opening 509 has a shape such that a suitable recessed element can be placed in the opening 509. In an embodiment, the fabric around the opening 509 is partially releasable to enable an easier insertion of the recessed element - for example, at a section of the fabric around the opening 509, there are two layers of fabric that are coupled to each other with velcro and if the two layers are released from each other, the opening is larger to enable the insertion of the recessed element.

Figure 5c schematically shows a three dimensional view a bottom side of a bag 550 that comprises an embodiment of a recessed element 560. The recessed element 560 is provided in the opening 509 of Figure 6b. The bottom side 562 of the recessed element 560 can be seen. The recess is indicated with 566. Figure 5c also show, for example, protaisions 569 that extend away from the bottom side 562 and which can be used to place the bag 550 on the ground.

Figure 7 schematically shows a support that is an integral part of a wheeled board accessory that is coupled to a stroller. Wheeled board accessories have been developed for many types of strollers. The wheeled board is a small board supported by at least one additional wheel and that is coupled to a rear wheel axis of the stroller. An additional child who is, for example, some years older than a child that is transported with the stroller can stand on the wheeled board. Thereby the user of the stroller is able to transport two kids. In Figure 7 the rear wheel axis 747 of the stroller can be seen. Figure 7 also shows a portion 799 of the wheeled board. The wheeled board has arms 797, 797’ that extend towards the rear wheel axis 747 of the stroller and are coupled to a coupling. The coupling of the wheeled board to the rear wheel axis of the stroller can also be used to support a luggage item with the recessed element 710 that is discussed in the context of previous figures. In other words, the support can be an integral part of the coupling for coupling the wheeled board to the rear wheel axis of the stroller. In the example of Figure 7, the coupling for coupling the wheeled board to the stroller has two joints 798, 798’. The joints 798, 798’are relatively large and protrude in an upwards directions. Thereby the joints 798, 798’ become the resting element of the support and a top surface of the joints that face towards, for example, the handlebar become the support surface of the support. In Figure 7 it has been shown how a recessed element 710 (that is provided in a bag or another type of luggage item) may rest on the joints 798, 798’ of the coupling of the wheeled board. In Figure 7 the recessed element 710 is shown as a partially transparent element and in practical embodiments it may be made of a non-transparent plastic. In Figure 7 the top side of the recessed element faces in an upwards direction.
