Description

Strollers and stroller frames!

description

The present invention relates to a stroller.

Strollers and stroller frames with attachments arranged thereon, on which one or more child receiving devices can be attached, are known in principle. In addition, it is known that such seat attachments can have different, sometimes changeable sitting positions for children, toddlers and / or babies.

In particular, the use of different seat attachments and / or differently adjustable seating positions of the seat attachments can sometimes lead to undesirable tilting situations, since a sufficiently high stability of the stroller cannot be guaranteed for every seat attachment and / or every adjustable seat position.

Such undesirable tipping situations can also arise, depending on the nature of the surface on which the stroller is standing. Furthermore, such tilting situations are favored by the fact that the stroller is not on a horizontal surface, but on an inclined surface, such as, for example, on an ascending or descending path. In particular, approaches are known from the prior art in which an attempt is made to solve the problem described above with warning notices that discourage certain (unstable) configurations in the operating instructions for the stroller. However, despite the corresponding warning notices in the operating instructions, there is still the risk that the warning notices will (accidentally) not be taken into account, which can lead to (accidental) misuse of the stroller.

It is therefore the object of the invention to provide a transport device, in particular a stroller, with increased stability. Another object of the invention is to provide, in particular, a stroller with (improved) protection against (accidental) misuse. The aforementioned tasks should preferably be achieved through inexpensive, simple, safe and user-friendly solutions.

Increased stability can in particular mean that the transport device, in particular the stroller, does not tilt in any direction at least up to a certain angle, for example about 8 ° or about 10 ° or about 12 ° or about 15 ° relative to the horizontal. The stroller should be able to be inclined in any direction, in particular directed downwards (so that the at least one front wheel is lower than the rear wheels, whereby a longitudinal direction of the stroller is perpendicular to a contour line of the inclined surface), directed upwards (so that the at least one front wheel is higher than the rear wheels, with a longitudinal direction of the stroller perpendicular to a contour line of the inclined surface) or laterally directed (so that a longitudinal direction of the stroller is parallel to a contour line of the inclined surface and / or so that a front wheel and a lateral boundary line connecting a rear wheel of a polygon defined by the support points of the wheels on which the transport device or the stroller stands is parallel to a contour line of the inclined surface). The object is achieved by a transport device according to claim 1 and a baby carriage according to claim 2, a baby carriage in accordance with 9, a baby carriage in accordance with 14 and a baby carriage in accordance with 18.

In particular, the object of the invention is achieved by a transport device, in particular a stroller, with a chassis which can be supported on a ground via at least three, in particular four, wheels and with at least two receiving devices, in particular child receiving devices, which can be connected to the chassis via adapters, the adapters designed and, if necessary, positioned on the chassis in such a way that they have at least one configuration with regard to connecting the receiving devices and their alignment (and possibly their manipulation) in which the overall center of gravity of the transport device and receiving device (s) (in particular with and / or without load or child or children, possibly only with or only without load) in plan view and thus the overall center of gravity is not within the projection area limited by the wheels or their standing areas (at least with a horizontal surface, possibly with all, flat, surfaces, the opposite it is less than or equal to 20 ° to the horizontal, or at least less than or equal to 5 °), do not allow, and / or allow only so that the overall center of gravity of the transport device and receiving device (in particular with and / or without load, if necessary . only with or only without load) in plan view (resp. View from above) and thus the overall center of gravity always within the projection area delimited by the wheels or their standing areas (at least with horizontal surfaces, possibly with all planar surfaces that are at an angle of less than or equal to 20 °, or at least at least, with respect to the horizontal have less than or equal to 5 °).

As an alternative or in addition, the adapters are designed (and, if necessary, can be positioned on the chassis) in such a way that they only allow connection of the receiving devices and their alignment (and possibly manipulation) of the same so that the overall center of gravity of the transport device including the receiving device (s) (in particular with and / or without a load, preferably a child, possibly only with or only without a load, preferably a child) always lies within the projection area delimited by the wheels (at least with a horizontal surface) when viewed from above. Preferably, at least one of the two (more preferably both) receiving devices can be connected in two different orientations (in particular forward and rearward orientations); Due to the above condition (s), however, possibly not to all connection structures or via all adapters, at least one of the receiving devices can, for example, be aligned both forwards and backwards on a first connection structure, but only forwards (or only backwards) on a second connection structure ). Alternatively or additionally, at least one of the receiving devices can be aligned (only) forwards on a first connection structure, but (only) backwards on a second connection structure. At least one of the receiving devices can optionally be aligned both forwards and backwards on both a first and a second connection structure.

A (respective, possibly first) receiving device (possibly several or all receiving devices) can possibly only be arranged on a certain (e.g. first) connection structure or at least not on all connection structures that are basically provided. Alternatively or additionally, a respective (possibly further or second) receiving device (possibly several or all receiving devices) can be arranged on several or all provided connection structures, for example an upper and a lower connection structure.

At least one receiving device cannot be arranged on at least one connection structure (connected to it) and / or cannot be aligned in a specific orientation on at least one connection structure (the specific orientation preferably being possible on at least one further or second connection structure).

Preferably, at least one structurally prevented arrangement (connection) and / or structurally prevented alignment and / or structurally prevented inclination setting is such that it would not meet at least one of the above conditions in the (only) theoretically considered case of implementation (in particular that the overall center of gravity of the transport device and receiving device (in particular, preferably with and / or without load, possibly only with or only without load in plan view - or, view from above - the Overall center of gravity, if necessary always, outside the projection area bounded by the wheels or their standing areas (at least with horizontal surfaces, possibly with all planar surfaces that are at an angle of less than or equal to 20 °, or at least less or equal to the horizontal, to the horizontal 5 °).

In particular, the (respective, structurally permitted) line of gravity extending through the overall center of gravity of the transport device should extend through the aforementioned projection surface. Then stability is guaranteed.

One idea of the invention is based in particular on the fact that (fictitious) connections between all points of contact between the wheels of the chassis and the ground result in a polygon (with connections located inside the polygon being disregarded), with one - on one through the polygon is a defined plane projected in the direction of action of gravity - the center of gravity is necessarily within the polygon in at least one configuration.

A point of contact means in particular the (contact) center point and / or respective (surface) center of gravity (contact center of gravity) (in the case of areal or at least essentially linear contact). If the respective wheel is rotatable, a state should preferably be assumed in which the wheel is configured for straight-ahead travel.

An undesirable tipping situation always occurs when the center of gravity and the line of gravity of the (preferably loaded) transport device (or the preferably loaded stroller) do not lie above the area of the polygon, i.e. outside the same in plan view.

The decisive factor is the direction given by gravity, i.e. whether a straight line running through the center of gravity in the direction of gravity runs through the polygon (then, by definition, the center of gravity is above the polygon and the stroller, possibly loaded stroller, does not tip) or not ( then, by definition, the center of gravity is not above the polygon and the pram, possibly loaded prams, can tip over). In embodiments, the stroller can have two front and two rear wheels, so that a quadrangle (in particular a rectangle or a trapezoid) results as a polygon in plan view. In other embodiments, the stroller can have a front wheel and two rear wheels, so that the result is a (in particular isosceles) triangle as a polygon.

With regard to the load, a loaded transport device (a loaded stroller) should be implemented in particular when the (or at least one) receiving device is loaded, i.e. when, for example, the receiving device or one of the receiving devices is a child receiving device and a child is accommodated therein , or if the receiving device or one of the receiving devices is a shopping basket in which there are, for example, purchases.

A load per receiving device can in particular be up to 10 kg, or more than 10 kg and up to 15 kg, or more than 15 kg and up to 22 kg, the loading of different receiving devices naturally not having to be the same.

The object of the invention is also achieved by a stroller, comprising: at least a first and a second receiving device, which are designed in particular as a child receiving device for receiving a child, toddler and / or baby and / or as a transport device; a stroller frame; at least one first and one second adapter, via which the receiving devices can be detachably connected to the stroller frame; wherein a first receiving device has at least one (first) adapter connection element with which the receiving device can be mechanically connected to the first and / or the second adapter, and a second receiving device has a (second) adapter connecting element with which the receiving device is exclusively connected to one, preferably the first, of the two adapters can be mechanically connected. An adapter is understood to mean, in particular, a pair of adapter elements, the adapter elements preferably being arranged on a section of one side of a strut and / or one side of a slide of the stroller frame, preferably symmetrically to one another with respect to a central plane of symmetry (running longitudinally through the stroller) are. The adapter and the corresponding adapter connection elements preferably each have at least one contact surface that touch one another or can at least be arranged very close to one another (at a distance of at most two or one millimeter) when the receiving device is connected to the adapter (the stroller frame) is.

The adapter can preferably form (or comprise) a receptacle with at least one side wall, the adapter connection element being mechanically coupled to the receptacle. The at least one contact surface of the adapter connection element can form part of the at least one side wall. When the adapter connection element is completely received in the receptacle of the adapter, further movement of the receiving device relative to the stroller frame is at least essentially not possible. The receiving device is then fixed to the transport device, in particular a stroller.

Another core concept of the invention is based on the fact that the stroller frame has at least two, namely a first (upper) and a second (lower) adapter. The lower adapter is here (in the state of use) closer to the ground and / or closer to the front wheels than the upper adapter. In this embodiment it can be provided that the stroller frame is used together with (at least) two receiving devices (child receiving devices). A first child receiving device can be designed in such a way that it can be connected to both the lower adapter and the upper adapter on the stroller frame. A second receiving device (child receiving device) can be designed in such a way that it can only be connected to one of the adapters, preferably the lower adapter, but not to the other (upper) adapter. In addition, it can be provided that the adapter connection element of the second receiving device (child receiving device) - but not that of the first receiving device (child receiving device) - has a projection, such as a rib or a tongue (in the sense of a tongue and groove connection) The lower adapter (but not the upper adapter) has a corresponding recess (a corresponding recess), for example a groove, which allows the adapter connection element of the second receiving device (child receiving device) to be mechanically connected to the lower adapter.

A mechanical connection of the second receiving device (child receiving device) to the upper adapter is thus prevented, whereas the first child receiving device is suitable to be connected to either the upper or the lower adapter.

Furthermore, a reversal is possible in such a way that the first receiving device (child receiving device) has a projection and / or the upper adapter has a recess (a recess). A reversal is also possible in such a way that one of the adapters has the projection and the adapter connection element of one of the receiving devices (child receiving devices) has a recess (a recess).

In particular, at least one of the two receiving devices (child receiving device) can be designed as a seat unit which has a seat section and a back section, wherein the back section can serve to lean against the back and head of a child. Furthermore, the seat unit can additionally have a leg section. The seat section and back section, and possibly the seat section and leg section, can be connected to one another in an articulated manner, so that differently inclined positions (sitting and lying positions) can be set, with a locking mechanism being provided to fix the respective positions.

In addition or as an alternative to this, all sections can be tilted together with respect to the receiving connection element provided for connection to the stroller frame, so that the seat unit can adopt different inclinations with respect to the frame Usually, a seat unit can be used either backwards or forwards and either rotatably connected to the stroller frame (preferably via a single adapter arranged in the middle in plan view, not designed as a pair), or alternatively removed from the stroller frame and put back on again rotated by about 180 ° will.

A receiving device designed as a bed unit

(Child support device) can have a (possibly padded) floor, for example one, two, three or more parts, as well as side walls for lateral delimitation. The bed unit can at least be connected to the frame in such a way that the floor is essentially horizontal is. In addition, if necessary, the bottom and side walls can be tilted together with respect to the counter structure provided for connection to the chassis, so that the bed unit can adopt different inclinations with respect to the frame. Usually, a reclining unit can be connected to the frame facing backwards. It can also be the case that the bed unit can be removed from the frame and put back on again, rotated by about 180 °. However, this is not common because very young children (who are transported in a bed unit) should always have eye contact with the person pushing them if possible.

A receiving device (child receiving device) designed as a combined seat / reclining unit can be transformed from a seat unit into a reclining unit by means of a suitable mechanism.

A receiving device designed as a baby seat (child receiving device) can be suitable for transporting a baby or toddler (usually up to an age of about one year or about 15 months, which is not relevant to the invention) in a motor vehicle, in particular in an automobile .

The baby seat can be made in one piece (monolithic), the one-piece baby seat being able to consist of several elements that are firmly connected to one another, or in several parts. In the multi-part design, the Baby seat have a seat section and a back section, wherein the back section can serve to rest your back and head.

Furthermore, the baby seat can have a leg section in some embodiments. The seat section and back section, and possibly the seat section and leg section, can be connected to one another in an articulated manner, so that differently inclined positions (sitting and lying positions) can be set, with a locking mechanism being provided to fix the respective positions.

In addition or as an alternative, all sections can be tilted together with respect to the adapter connection element provided for connection to the stroller frame, so that the seat unit can assume different angles of inclination with respect to the stroller frame. Usually a baby seat can be connected to the stroller frame facing backwards.

It can also be the case that the baby seat can be removed from the stroller frame and rotated by 180 ° to put it back on. However, this is not common because very young children (who are transported in a baby seat) should always be able to make eye contact with the person pushing the car if possible.

The stroller frame can comprise various frame parts, in particular one or more front wheel struts, one or more rear wheel struts and a slide, and possibly further struts or frame parts. Two or more frame parts can be connected to each other, either fixed or movable, e.g. articulated or telescopic.

Furthermore, the stroller frame can comprise several wheels, in particular two rear wheels and at least one front wheel. Each wheel can rotate (at least) about a horizontal axis, with preferably all rear wheels rotating about the same first axis. The first axis can in particular be designed as a physical axis. The at least one front wheel can rotate about a second axis, the second axis being parallel to the first axis when driving straight ahead. Can / can, in particular to facilitate cornering at least one of the or all wheels may be rotatable about a (each) vertical axis.

When the stroller is not tilted, all wheels touch the ground. In the case of the children's frame, tilting forward can mean that the at least one front wheel continues to touch the ground while one or more (in particular all) of the rear wheels lift off the ground. Tilting backwards can be understood to mean that the rear wheels continue to touch the ground while one (or, if present, several, in particular all) of the at least one front wheel lifts off the ground.

All the features and associated advantages that have been described in connection with the transport device according to the invention can be used and transferred to the stroller according to the invention.

In particular, the first adapter has at least one recess, which is in particular designed as a groove, and the adapter connection element of the second receiving device has at least one projection, in particular complementary to the recess of the first adapter, which is in particular designed as a rib. As a result, a secure connection of the adapter connection element of the second receiving device to the first adapter is achieved in the simplest possible way.

In one embodiment, the at least one projection of the adapter connection element of the second receiving device couples with the recess of the first adapter when the receiving device is connected to the first adapter in a first orientation, whereby the receiving device is connected to the first adapter in a first orientation and thereby the stroller frame is connected.

The first adapter preferably has a further recess, which is also designed in particular as a groove, and the at least one projection of the adapter connection element of the second receiving device couples with the further recess of the first adapter when the receiving device is in a further, preferably for the first orientation at least essentially opposite orientation is connected to the first adapter. This makes it possible to connect the receiving device in a second orientation to the first adapter and thereby to the stroller frame.

In particular, the second adapter has an at least substantially planar contact surface, and in particular the adapter connection element of the first receiving device also has an at least substantially planar contact surface, which mechanically prevents the at least one projection of the adapter connecting element from contacting the second receiving device can be coupled to the second adapter.

In a further embodiment, the adapter or adapters is or are arranged on the first and / or second receiving device instead of on the stroller frame, and the associated adapter connection elements are arranged on the stroller frame.

In addition, the object of the invention is achieved by a stroller, comprising: at least one first and one second receiving device, which are designed in particular as a child receiving device for receiving a child, toddler and / or baby and / or as a transport device; a stroller frame; at least one first and one second adapter, via which the receiving devices can be detachably connected to the stroller frame; wherein the first receiving device comprises a seat portion and a back portion pivotable relative thereto and a mechanism for adjusting an angle of inclination of a first number of angles of inclination between the back portion and seat portion and the second receiving device comprises a seat portion and a back portion pivotable relative thereto and a mechanism for adjusting the angle of inclination a second number of angles of inclination between the back section and the seat section that is different from the first number.

In addition, the object of the invention (in particular as an alternative or in addition to the preceding paragraph) is achieved by a stroller, comprising: at least one first and one second receiving device, which are designed in particular as a child receiving device for receiving a child, toddler and / or baby and / or as a transport device; a stroller frame; at least one first and one second adapter, via which the receiving devices can be detachably connected to the stroller frame; wherein the first receiving device comprises a seat portion and a back portion pivotable relative thereto and has a mechanism for adjusting an angle of inclination between the back portion and the seat portion, and the second receiving device comprises a seat portion and a back portion pivotable relative thereto and a mechanism for adjusting the angle of inclination between the back portion and the seat portion having, wherein with the mechanism for adjusting the angle of inclination of the first receiving device at least one specific angle of inclination can be set, which cannot be set by the mechanism for adjusting the angle of inclination of the second receiving device, and / or wherein the mechanism for adjusting the angle of inclination of the second Recording device at least a certain angle of inclination can be set, which is of the mechanism for adjusting the angle of inclination of the first recording direction cannot be set.

Another aspect of the present invention is based on the fact that the first receiving device (child receiving device) can furthermore be adjustable in a plurality (for example two or more) of inclination positions.

As described above, this can be done either by tilting the counter-structures with respect to the other parts of the receiving device (child receiving device), or by pivoting individual sections relative to one another.

In particular, the mechanism of the first receiving device allows a greater number of different angles of inclination to be set between the back section and the seat section than the corresponding mechanism of the second receiving device, whereby systematically specific angles of inclination of the second receiving device between the back section and the seat section can be avoided. It is preferred that at least one (upright) sitting position, one (flat) lying position and at least one intermediate position are adjustable. The sitting position can have an angle (angle of inclination) of the back section with respect to the seat section of approximately 90 ° to approximately 140 °, preferably of approximately 105 ° to approximately 125 °. The reclining position can have an angle (angle of inclination) of the back section with respect to the seat section of approximately 140 ° to approximately 180 °, preferably of approximately 150 ° to approximately 170 °. A first or more intermediate positions can have an angle (angle of inclination) of the back section with respect to the seat section which is greater than the angle in the sitting position but smaller than the angle in the lying position.

For an optionally present second intermediate position, the angle (angle of inclination) of the back section with respect to the seat section can be greater than the angle in the first intermediate position, but smaller than the angle in the lying position. The angles (angles of inclination) for any third and further intermediate positions that may be present can be defined in the same way as above. In a specific embodiment, a seat position with an angle (angle of inclination) of at least about 115 °, a first intermediate position with an angle (angle of inclination) of at least about 130 °, a second intermediate position with an angle (angle of inclination) of at least about 145 ° and a Lying position be designed with an angle (angle of inclination) of at least about 160 °.

The second receiving device (child receiving device) can (among other things) differ from the first in that one or more of the inclination positions is or are not available (or not adjustable). The most inclined position (especially the lying position) can be the or one of the nonexistent positions. However, one or more of the intermediate positions can also not be present (if these are present in the first child accommodation facility). In particular, the lack of an intermediate position can be preferred for positions with an angle of at least about 130 ° to at least about 150 °, preferably at least about 140 ° to less than at least about 150 °. This is because from a certain angle a different distribution of the mass in the child receiving device is to be expected, so that a position with a An angle of just under at least about 150 ° can be more critical than a position with an angle of at least about 160 °,

In particular, the second receiving device (child receiving device) can provide the same sitting position and the same lying position as the first receiving device (child receiving device), but not the intermediate position or one of the several intermediate positions and disengaged to unlock. Specifically, it can be, for example, a toothed ring (with outwardly pointing teeth or projections) and a rotating ring (i.e. a ring with recesses on the inner surface), or one or more pins for engaging corresponding holes in the counter structure.

In addition, all the features and associated advantages that have been described in connection with the transport device according to the invention and the above-described baby carriage according to the invention can be used and transferred to the (following) baby carriage according to the invention.

In particular, the mechanism of the first receiving device allows the setting of a greater number of different angles of inclination between the back section and the seat section than the corresponding mechanism of the second receiving device. In this way, particularly in the case of the second receiving device, the use of the receiving device with angles of inclination between the back section and the seat section, which are unfavorable for the stability of the stroller, can be avoided.

In one embodiment, at least the following positions can be set by the mechanism for adjusting the angle of inclination between the back section and the seat section of the first receiving device: a seat position in which the angle of inclination of the back section with respect to the seat section is in a range of at least approximately 90 ° to at least approximately 140 °, preferably from 105 ° to 125 °; a reclining position in which the angle of inclination of the back section with respect to the seat section is in a range of at least approximately 140 ° to at least approximately 180 °, preferably from at least about 150 ° to at least about 170 °; and one or more intermediate positions in which the angle of inclination of the back section with respect to the seat section is smaller than the angle of inclination in the lying position and greater than the angle of inclination in the sitting position. This allows a particularly comfortable setting of the angle of inclination of the back section with respect to the seat section.

In particular, at least the following positions can be set by the mechanism for adjusting the angle of inclination of the second receiving device: a sitting position in which the angle of inclination of the back section with respect to the seat section is in a range of at least about 90 ° to at least about 140 °, preferably of at least about 105 ° to at least about 125 °; a reclining position in which the angle of inclination of the back section with respect to the seat section is in a range from at least about 140 ° to at least about 180 °, preferably from at least about 150 ° to at least about 170 °; and one or more intermediate positions in which the angle of inclination of the back section with respect to the seat section fulfills at least one of the following conditions: the angle of inclination is less than approximately 150 °, preferably less than approximately 140 °, and greater than the angle of inclination in the sitting position; and the angle of inclination is greater than about 150 °, preferably greater than about 155 °, and smaller than the angle of inclination in the lying position. In this way, on the one hand, the angle of inclination of the back section relative to the seat section can be set particularly comfortably, whereby a certain range of the angle of inclination between about 140 ° and about 150 ° can be avoided, which has a particularly unfavorable effect on the tilting properties of the stroller.

The object of the invention is further achieved by a stroller, comprising: at least a first and a second receiving device, which are designed in particular as a child receiving device for receiving a child, toddler and / or baby and / or as a transport device; a stroller frame; at least one first and one second adapter, via which the receiving devices can be detachably connected to the stroller frame; wherein at least one, preferably the first, of the two adapters has an adjustment mechanism via which the at least one adapter can be detachably connected to the stroller frame, in particular the position of the at least one of the two adapters in a horizontal and / or vertical direction in relation is adjustable on the stroller frame.

Another aspect of the invention is based on the fact that the stroller frame of the stroller has in particular at least one first (upper) and at least one second (lower) adapter. In particular, the stroller frame can have exactly two, namely a lower and an upper adapter. The second (lower) adapter should be able to be attached closer to the ground and / or closer to the front wheels than the first (upper) adapter. The second (upper) adapter should be adjustable between a front and a rear position on the frame. The adapter position can be adjusted using an adjustment mechanism. It can be provided that the stroller frame is used together with (at least) two receiving devices.

Here, too, all the features and associated advantages that have been described in connection with the transport device according to the invention and the above-described prams according to the invention can be used and transferred to the following prams according to the invention.

In one embodiment, the at least one of the two adapters is displaceably mounted on the stroller frame, in particular along the side of this strut that extends from the rear top to the front bottom, so that the position of the at least one of the two adapters can be particularly easily adjustable.

In particular, the at least one of the two adapters can be fixed, in particular latched, with the adjusting mechanism in several different positions on the stroller frame. This allows the position of at least one of the two adapters to be adjusted and fixed in a simple and convenient manner. The at least one is preferably the Both adapters can be fixed in exactly or at least three positions on the stroller frame with the adjustment mechanism, in particular they can be locked in place.

The object of the invention is further achieved by a stroller, comprising: at least one receiving device, which is designed in particular as a child receiving device for receiving a child, toddler and / or baby and / or as a transport device; a stroller frame; at least one adapter via which the receiving device with the

Stroller frame are releasably connectable; wherein an adapter connection element of the receiving device has a blocking mechanism for blocking a mechanism formed on the receiving device for adjusting the angle of inclination between the back section and the seat section, the angle of inclination adjusting mechanism being blocked by the blocking mechanism when the receiving device is over in a first orientation the adapter is connected to the stroller frame, while the inclination angle adjustment mechanism is not blocked, in particular by the blocking mechanism, when the receiving device is connected to the stroller frame via the adapter in a further orientation, preferably at least substantially opposite to the first orientation.

A further aspect of the invention is based on the fact that the receiving device (child receiving device) can be brought (adjusted) into different positions or orientations, whereby, for example, by tilting individual sections of the receiving device to one another, the adapter connection element (the contact projection surface of the adapter) has a blocking Mechanism can be actuated, whereby an influence on the setting options and / or the setting of the receiving device can be achieved.

Specifically, a blocking mechanism can be designed as a (possibly spring-loaded) pin which is arranged asymmetrically with respect to a (fictitious) vertical axis through the center of the adapter connection element. The pen can be in in the first position (e.g. in the sitting position) and not in the second position (e.g. in all positions except the sitting position), because e.g. by changing the position, an element connected to the backrest, e.g. provided with a recess can be blocked by the pin.

Furthermore, the adapter can be designed on one side (which e.g. corresponds to a forward connection of the child-carrying device to the stroller frame) in such a way that space remains free for the pen so that the pen is not displaced. In the other direction (which corresponds, for example, to a rearward connection of the child restraint device to the frame), for example, a bevel or a comparable structure can be arranged on the adapter so that the pin is pressed in when the child restraint device is connected to the adapter (the stroller frame) becomes.

The movement of the element can be blocked or restricted by the pin when the pin is pushed in, for example by receiving the pin in a corresponding hole, slot or recess. In this way it can be realized that the child receiving device can be connected to the stroller frame in a first orientation, with all positions being accessible here. In contrast, the child receiving device can only be connected to the frame in the other orientation if it is in a suitable position, the other positions not suitable for connection being inaccessible even in the connected state.

The aforementioned positions usually mean different angles between the seat section and the back section of a child seat unit.

Furthermore, all the features and associated advantages that were described in connection with the transport device according to the invention and the above-described baby carriage according to the invention can be used and transferred to the (following) baby carriage according to the invention. In a further embodiment, the adapter has a contact projection surface which is arranged such that the contact projection surface actuates the blocking mechanism when the receiving device is connected to the stroller frame via the adapter in a first orientation. In this way, it is prevented in a structurally simple manner that the receiving device can be brought into a flatter (lying) position when the receiving device is connected to the adapter in a first orientation. It is thus prevented that in a first orientation in which, for example, an increase in the angle of inclination of the back section with respect to the seat section would have an unfavorable effect on the stability of the stroller, the angle of inclination of the back section with respect to the seat section can be increased.

The blocking mechanism preferably has a spring-loaded pin which is pressed by the contact projection surface of the adapter against a restoring force acting on the spring-loaded pin into a recess, preferably in a recess of the tilt angle adjustment mechanism, so that the tilt angle adjustment mechanism locks or blocks becomes. In this way, a blocking mechanism is created in a simple, constructive manner, in the case of a child seat unit around an axis that preferably extends approximately vertically to the seat surface of the seat section, with the functionality specified above.

In particular, the receiving device is rotatably mounted on the stroller frame, in particular about an approximately vertically extending axis, whereby the receiving device can be aligned very easily in several possible orientations with respect to the stroller frame.

It is preferred that the rotational position of the receiving device is adjustable, in particular lockable in two positions. The receiving device can preferably be locked in a forward-facing position and in a rearward-facing position. In particular, the receiving device can be connected to the stroller frame via a rotatably mounted adapter, in particular an adaptive turntable. It is preferred that the rotatably mounted adapter, in particular the turntable, or the receiving device is assigned a switching element such as a slide, rotary knob, button, or push button or the like, with which the adjustable rotational positions or orientations of the receiving device can be fixed.

In a further embodiment, the switching element can only be adjusted from a first switching position to at least one second switching position when the receiving device is not coupled to the adapter, in particular not fixed to the adapter.

In particular, the rotatably mounted adapter is unlocked and the rotational positions or orientations of the receiving device can be freely determined if the switching element is in the first switching position.

The receiving device can preferably be locked in a forward-facing position and in a rearward-facing position, provided that the switching element is in the second switching position.

In a further embodiment, the receiving device can be designed not only for transporting a child, toddler or baby but also as a device for transporting animals or other objects.

Further embodiments emerge from the subclaims.

In general, a stroller comprises a frame (stroller frame) and at least one receiving device. The receiving device is detachably connected to the frame, for example by means of at least one adapter which is / are provided on the frame for this purpose. The receiving device is preferably a child receiving device, in particular a seat unit, a reclining unit, a combined seat / reclining unit or a baby seat (suitable for transporting a toddler in a motor vehicle), but it can also be another transport device, e.g. a Shopping basket or other transport device for transporting objects act. The receiving device comprises complementary counterparts to the adapter on the frame or to the adapters on the frame, or it can be releasably connected to these via intermediate adapters. In particular, the frame can also comprise several adapters for fastening one or more receiving devices, preferably exactly one adapter or exactly one adapter pair per receiving device. In this context, in the following, unless otherwise explicitly mentioned, an adapter is to be understood as that structure which is provided for connection to exactly one receiving device, even if it is, for example, a pair of adapter elements (e.g. a right and a left adapter element). A stroller within the meaning of this invention is also present in particular when adapters for several receiving devices are present, but only one receiving device is connected to the frame. With strollers of this type, depending on the configuration, it can happen that the stability or stability is not as good as desired, or in other words, that the entire stroller can tip over more easily than desired, in particular forwards or backwards, possibly also to the Side or in an intermediate direction.

In one embodiment, at least one of the adapters and / or the counterpart of a receiving device, preferably a child receiving device that can be connected in a forward and backward direction, has an asymmetry. This is a central (advanced or independent) idea of the invention. The asymmetry makes it possible to differentiate the setting options available in the forward or backward direction of the child receiving device (with regard to the frame). In order to enable the child support device to be connected both forwards and backwards, at least either the adapter or the counterpart can essentially have a twofold rotational symmetry. The asymmetry is a deliberate deviation from this principle, which can in particular be designed structurally. For example, it can be a protrusion or a recess, with a protrusion possibly also being designed to be movable, e.g. as a pin that can be pushed in. The asymmetry should preferably relate to the contact surface of the adapter and / or the counter structure.

In a further exemplary embodiment, the child receiving device has a fixed projection, for example a rib, in the counter structure. The adapter has a groove in a front area in such a way that the child support device can only be connected to the frame in a forward direction but not in a rearward direction (or exactly the other way around). It goes without saying that the projection and groove can be interchanged.

According to the embodiment, the frame can have at least two adapters (for fastening at least two receiving devices), in particular at least one lower and at least one upper adapter. In particular, the frame can have exactly two, namely a lower and an upper adapter. The lower adapter should be closer to the ground and / or closer to the front wheels than the upper adapter. The upper adapter should be adjustable between a front and a rear position on the frame. The adapter position can be adjusted in various ways, but preferably by moving it. According to the invention, it can be so that the upper adapter has an asymmetry in its rear position that it does not have in the front position (or vice versa) by inserting an asymmetry element during the adjustment (during displacement) and caused by this between a rest position and an active position is adjusted, the asymmetry only interacts in the active position with the counterpart of the child restraint device (and e.g. prevents its attachment to the frame or restricts it to certain positions such as the sitting position), and does not interact with the counterpart of the child restraint device in the rest position.

In a further exemplary embodiment, the frame has an adapter and the child receiving device has a counterpart, which enables a rotatable connection between the frame and the child receiving device. The rotation should take place around an essentially vertical axis. The child receiving device should be able to be locked in at least two, preferably exactly two, positions with respect to the frame. The two positions are particularly preferably a forward-facing and a backward-facing position. In addition, the child restraint device should have a switch that allows the child restraint device to be positioned between a first (for using the child restraint device with a maximum load of 15 kg) and a second position (for using the child restraint device with a maximum load of 22 kg). At the Switch can be, for example, a slide button or a rotary button or a push button or a toggle switch. The switch should preferably only be able to be adjusted from the first position to the second position and back when the child support device is completely detached from the frame. If the switch is in the first position, the child support device can be connected to the frame in all (both) lockable positions, and rotation is possible without restriction when the child support device is connected to the frame and the position lock is open. However, if the switch is in the second position, a connection is preferably only possible in a forward position of the child receiving device with respect to the frame; in addition, the rotation of the child receiving device with respect to the frame is not possible. This can specifically be achieved in that, for example, the adapter of the frame has a recess or receptacle in its contact surface that is not rotationally symmetrical with respect to the essentially vertical axis of rotation. The contact surface of the counter structure of the child support device can accordingly have a corresponding asymmetry element which is sunk into the contact surface of the counter structure and thus assumes a rest position when the switch is in its first position. By moving the switch to its second position, the asymmetry element can also be moved into an operative position in which it forms a projection with respect to the surrounding contact surface of the counter structure which, in the forward position of the child support device opposite the frame, interacts with the receptacle or recess in the adapter can, but in all other positions (especially in the rearward-facing position) blocks a connection between the child support device and the frame (because there is no receptacle or recess at the corresponding position of the contact surface of the adapter), and at the same time a rotation of the child support device relative to the Frame only allowed within the limits specified by the dimensions of the receptacle or recess, the receptacle or recess preferably being just as wide as the projection.

The above-mentioned object is also achieved in particular by a system and / or an arrangement comprising the above stroller and at least or exactly one child in the first receiving device and / or at least one or exactly one child in the second receiving device.

The above-mentioned object is also achieved in particular through the use of the above stroller and / or above system, with at least or exactly one child being placed in the first receiving device and / or at least one or precisely one child being placed in the second receiving device, preferably for accommodation and / or transporting the child (s).

The above-mentioned object is also achieved in particular by a method comprising accommodating and / or transporting at least one child, the above stroller and / or the above system preferably being provided for this purpose. The functional features and / or purpose information explained in the context of the stroller or the system can be carried out as method steps with regard to the method.

Insofar as conditions with load or without load (and corresponding conditions) are mentioned above, this should mean, in particular with regard to the system, the use and the method, that once a center of gravity is to be determined (completely) without child or children and the other Sometimes a focus determination with at least one child in at least one reception facility, possibly with several children in the several reception facilities or at least or exactly one child in each reception facility.

In the following, the same reference numerals are used for parts that are the same or have the same effect.

Fig. 2 shows a schematic representation of a stroller 1 with two receiving units 20, 30 in an oblique view. Four wheels 42 (two front wheels and two rear wheels) are attached in the lower region of the frame 40 or the stroller frame 40. A first adapter 50 and a second adapter 60 are fixed to the frame 40. In addition, a first receiving device 20 is coupled to the first, upper adapter 50 in FIG. 2. The first receiving device is aligned in the direction of travel of the stroller 1. The second receiving unit 30 is coupled to the second, lower adapter 30. The second receiving device 30 is oriented opposite to the direction of travel of the stroller 1.

In this exemplary embodiment, a projection 311 of the adapter connection element 31 is designed as a rib which runs approximately vertically when the chassis 40 of the stroller is ready for operation. The adapter connection element 21 (not shown here) of the first receiving device 20 can be identical except for the rib that is missing there. An adapter connection element 31 which has a second rib (not shown) on the right-hand side would also be conceivable. FIG. 4 shows a schematic detailed view of an adapter element of the first adapter 50. In this exemplary embodiment, the first adapter 50 is preferably the upper adapter 50. In FIG. 4, the first recess 51 is also designed as a groove. In addition, the first adapter 50 has two recesses 52 which, in this exemplary embodiment, are also designed as a groove. Furthermore, the first adapter 50 has a contact surface (no reference symbol). By means of the first adapter 50, a connection of the frame 40 with either the first or the second child-carrying device 20, 30 (not shown) can thus be achieved.

In Fig. 6c the first adapter is fixed in a front lower position,

7 shows a schematic detailed view of an adapter connection element 21 of a receiving unit 20 in an oblique view. In this exemplary embodiment, the adapter connection element 21 has a blocking element 201, which is designed as a pin that can be pushed in against the force of a compression spring (not shown). When the blocking element 201 is pressed in, the blocking element 201 comes into contact with an element 202 of a tilt angle adjusting mechanism (not shown) in such a way that the tilt angle adjusting mechanism (not shown) is locked or blocked. The inclination angle adjustment mechanism is used to adjust the inclination angle of the child support device in relation to the horizontal,

FIG. 8 shows a schematic detailed view of an adapter connection element 21 of a receiving unit 20 in a sectional view. In FIG. 8, the blocking element 201 is shown in a depressed state, the Blocking element is pressed against a restoring force of a spring (not shown). The pressed-in blocking element (pin) is also pressed into a recess (a recess) 203 of an element 202 of the inclination angle adjusting mechanism (not shown), so that the inclination angle adjusting mechanism (not shown) is locked or blocked.

The element 202 of the inclination angle adjustment mechanism is fixedly connected to the back portion of the receiving device 20 and has only one recess (a hole) for cooperation with the pin. This one recess corresponds to the sitting position of the admissible receiving device 20. In principle, two or three holes corresponding to the pin 201 for setting different angles of inclination of the child receiving device are also conceivable. 9 shows a schematic detailed view of a seat section 22 of a receiving unit 20 in an oblique view. Furthermore, FIG. 9 shows a switching element 24.

FIG. 10 shows a schematic detailed view of a seat section 22 of a receiving unit 20 in a plan view from below. Furthermore, FIG. 10 shows the switching element 24. FIG. 11 shows two different states or positions of the switching element 24.

A schematic detailed view of a seat section of a receiving unit in a plan view from below is shown in FIG. 12, with the adaptive turntable in particular being shown in detail.

In FIG. 13, a schematic representation of a stroller 1 with a receiving unit 20 is shown in an oblique view.

14 and 15 show another example of a mechanism for adjusting the angle of inclination between a back section and a seat section of a first receiving device in the form of a first seat unit (FIG. 14) and a mechanism for adjusting the angle of inclination between a back section and a seat section a second receiving device in the form of a second seat unit (Fig. 15) shown schematically. The one in Fig. 14 The mechanism shown allows four different angles of inclination, while the mechanism shown in FIG. 15 allows only three different angles of inclination. Specifically, in FIGS. 14, 15 a type of toothed ring 70 can be assigned to a seat section that is essentially horizontally aligned in the assembled state, while a complementary rotating ring 71 is part of a back section that can be used opposite the seat section.

14, 15 each show a locking position between toothed ring 70 (with radially outwardly pointing teeth 72 or similar projections) and rotating ring 71 (here in the form of a flat ring with recesses 73 complementary to the aforementioned teeth 72).

To unlock the teeth 72 must be removed from the complementary recesses or recesses 73 so that the parts 70, 71 can then be pivoted relative to one another about an axis 74 defined by the joint axis between the seat section and the back section. For this purpose, the ring gear 70 can either be displaced radially to the axis 74, i.e. in the direction of the arrow 75 in FIGS. 14, 15, or in the direction parallel to the axis 74 until the teeth 72 disengage from the associated recesses or recesses 73 .

The locking takes place in the opposite direction after setting the desired angle of inclination.

It should also be pointed out that in the embodiment according to FIG. 15 the two teeth 72 of the toothed ring 70 are prepared differently. In the same way, the turntable 71 also has recesses 73 of different widths, the arrangement of these recesses 73 being such that with the same number of recesses as in the embodiment according to FIG. 14, only three instead of four different angular positions of the parts 70, 71 relative to one another possible are.

The inclination of the back section assigned to the turntable 71 relative to the seat section in the case of the first and second child support devices can then also be set correspondingly differently, each in the form of a seat unit.
