[0001] Stroller with drive device

[0002] Description

[0003] Strollers in general, but also powered strollers, have been known for many years, including from US 6148942 A. US 6148942 A discloses a stroller with a motor drive for only one child. The front wheels of the disclosed stroller have internal teeth and are driven by smaller pinions. For parents of two small children, such as twins, it is impractical to have to purchase and use two such strollers, especially because one parent cannot then travel alone with both children. Furthermore, the disclosed solution requires precisely coordinated components with tight tolerances, for example, regarding the exact shape and position of the teeth.

[0004] Sibling strollers are also generally known. However, sibling strollers with a motor are not yet known.

[0005] It is therefore an object of the present invention to provide a stroller that can also be used for two children. A further object of the invention is to provide a low-maintenance stroller that allows for greater manufacturing tolerances. It is also an object of the invention to provide a cost-effective, safe, and easy-to-assemble stroller.

[0006] At least one of the objects is achieved by a stroller comprising a frame, at least one wheel and a drive device, wherein the drive device is configured to drive the stroller. The stroller comprises a first child-carrying device and a second child-carrying device, wherein the second child-carrying device (in at least one usage configuration, optionally in several or all usage configurations) is arranged behind the first child-carrying device and / or higher than the first child-carrying device, and / or wherein the frame comprises a pusher section and the second child-carrying device (in at least one usage configuration, optionally in several or all usage configurations) is arranged closer to the pusher section than the first child-carrying device, or wherein the first child-carrying device and the second child-carrying device (in at least one usage configuration, optionallyin several or all usage configurations) are arranged next to each other.

[0007] "Behind" refers to the usual direction of movement of the stroller, i.e. the second child restraint is located in this case horizontally closer to the handle area of ​​the stroller's push bar than the first child restraint.

[0008] "Higher" means in particular that the first child pickup direction is positioned closer to the ground than the second child pickup direction.

[0009] Usage configurations correspond in particular to configurations in which at least one child could be transported in the stroller. A usage configuration preferably corresponds to a configuration in which at least one, preferably several, child restraints are (removably) connected to the stroller, more preferably to the stroller frame.

[0010] At least one of the objects is further achieved by a stroller comprising a frame, at least one wheel, a drive device, and a transmission device. The transmission device is configured to transmit torque from the drive device to the at least one wheel in order to drive the stroller, wherein the drive device is movably arranged on the frame. The drive device can be designed as a motor and can be pivotably (optionally exclusively pivotably) mounted about a first axis.

[0011] Preferably, the first child support device is detachably connected to the frame via a first adapter and / or the second child support device is detachably connected to the frame via a second adapter.

[0012] In preferred embodiments, the stroller, in particular the frame of the stroller, comprises a lower frame and a pusher section (in particular the above-mentioned pusher section), wherein the pusher section is arranged on an upper section of the lower frame. The stroller comprises at least one wheel, preferably at least or exactly three wheels, more preferably at least or exactly four wheels, wherein the at least one wheel or wheels can preferably be arranged on a lower section of the lower frame. The pusher section of the stroller is preferably the part of the frame which transmits forces and / or torques that the operator applies to the stroller during normal use of the stroller. In particular, the pusher section comprises the handle section of the stroller, which serves the operator to hold and / or push the stroller.

[0013] The lower frame can preferably be understood as the part of the chassis which rests on the wheels and bears at least the substantial weight of the stroller.

[0014] The lower frame preferably comprises a front wheel frame section and a rear wheel frame section, which are in particular rotatably connected to one another via a first joint. The slider section is preferably rotatably (directly) connected to the front wheel and / or rear wheel frame section via a second joint and / or displaceably connected to the front wheel frame section. In particular, the first and second joints can be identical to one another, so that the front wheel frame section, rear wheel frame section, and slider section are rotatably connected to one another in a common joint.

[0015] Preferably, at least one wheel is a rear wheel and / or is arranged at a lower and / or rear end of the rear wheel frame section and / or at least one wheel is a front wheel and / or is arranged at a front and / or upper end of the front wheel frame section.

[0016] The front wheel and / or rear wheel frame section may comprise (at least or exactly) one right and (at least or exactly) one left side strut, which may be connected to each other by at least one cross strut.

[0017] The slider section may have (at least or exactly) one right and (at least or exactly) one left side strut, wherein the slider section preferably has a handle area arranged between the right and left side struts of the slider section. A central connecting handle area may also be omitted.

[0018] The first and / or the second joint may comprise a right and a left joint section, which may be connected to each other via a cross strut.

[0019] The stroller can have a child support device (in particular the above-mentioned first child support device) and / or can be or become detachably connected to it. A child support device is to be understood in particular as a child seat and / or a carrycot and / or an infant carrier and / or the like. The stroller can be designed such that the child support device and / or a first adapter, in particular the above-mentioned first adapter, for connecting to the child support device is arranged in an upper section of the lower frame or on the push bar section. The first adapter can comprise a right-hand and a left-hand adapter element, wherein each of the adapter elements can preferably have a coupling section, in particular one facing upwards.

[0020] In embodiments, the stroller has a second adapter (in particular the above-mentioned second adapter) for connecting to a child-carrying device (in particular the above-mentioned second child-carrying device), wherein the second adapter (in at least one, possibly several, or all, usage configurations (in which the stroller can be used for child transport)) is preferably arranged below and / or in front of the first adapter, in particular closer to the at least one front wheel than the first adapter and / or in a lower / front region of the front wheel frame section. The second adapter can comprise a right-side and a left-side adapter element, wherein each of the adapter elements can preferably have a coupling section.

[0021] In embodiments, one of the first adapter and the second adapter (preferably the first adapter) is arranged displaceably (possibly, in particular exclusively, translationally displaceably) on the frame and / or one of the first adapter and the second adapter (preferably the second adapter) is arranged rotatably (possibly exclusively rotatably) on the frame.

[0022] Translational displaceability is understood in particular to mean that the adapter moves or displaces at least substantially linearly relative to the frame during the displacement. Rotatability, on the other hand, is understood in particular to mean that the adapter performs at least substantially a rotational movement, with preferably a section of the frame forming and / or enclosing the rotation axis.

[0023] In particular, the first adapter can be displaceable along the side struts of the slider section and / or the front wheel frame section, for example, via a rail or by engaging the side struts. In a specific example, the right-side adapter element can be displaceably guided on the right side strut and / or the left-side adapter element can be displaceably guided on the left side strut. The second adapter can, in particular, be rotatable between a use position in which the coupling section points upwards and a stowed position in which the coupling section no longer necessarily points upwards (but, for example, downwards or backwards).The coupling section is preferably the section via which the child restraint device is actually coupled to the adapter, i.e. preferably the area where the child restraint device is connected to the adapter, preferably in a form-fitting manner. Preferably, the first child restraint device and / or the second child restraint device can be connected to the frame either facing forwards or backwards. This allows the correct orientation to be selected as required; in particular, the orientation - forwards or backwards - of the second child restraint device can be selected independently of the orientation of the first child restraint device. As an alternative or as an additional orientation option, a lateral orientation of the first child restraint device and / or the second child restraint device is also conceivable.

[0024] In particular, "forward" and "backward" refer to the usual (horizontal) direction of movement or travel of the stroller. Preferably, a

[0025] "rearward-facing" child restraint system in the direction of the handlebar grip area.

[0026] Preferably, however, the first child restraint and / or the second child restraint cannot be connected to the frame in such a way that they are oriented laterally. Provision can be made for the first child restraint and / or the second child restraint to be connected to the frame exclusively in either a forward-facing or rearward-facing position.

[0027] A lateral orientation is preferably understood to mean a direction, in particular a horizontal direction, orthogonal to the "forward-backward" direction.

[0028] This allows the design to be kept simple while still ensuring sufficient flexibility. Furthermore, it can be provided that no more than one first child restraint and one second child restraint can be connected to the frame at the same time. This allows the stroller to be kept relatively compact.

[0029] The stroller preferably comprises a control device for controlling the drive device. The control device can be arranged in a push-bar section of the stroller. Alternatively or additionally, the control device can comprise a child safety lock. The control device can comprise an actuating device, in particular a manual actuation, for example a button and / or a slider and / or a rotary control and / or the like.

[0030] The control device can be electrically and / or wirelessly connected to the drive device. The actuating device can be configured to control the drive device by means of the control device. The child safety lock can, for example, be a release device of the actuating device, such that the actuating device can only be actuated and / or can only control the drive device by means of the control device if the release device is actuated before and / or during actuation of the actuating device. For example, the release device can (physically) block the actuating device as long as the lock is not actuated.

[0031] In general, a child safety lock makes the stroller safer because it can prevent a child placed in a child restraint located close to the push bar and facing the handle area from driving the stroller.

[0032] In a specific embodiment, the release device can selectively assume a release state and a non-release state, and the actuating device can selectively assume an actuated state and a non-actuated state. Then, it can be provided that the control device is configured to control the drive device to drive (in particular propel) the stroller when the release device is in the release state and when the actuating device is in the actuated state. Furthermore, it can be provided that the release device does not and cannot change from the release state to the non-release state as long as the actuating device is in the actuated state.

[0033] This makes it particularly difficult for the stroller to react suddenly and unintentionally if the operator and / or the child come into contact with the release device while the stroller is in motion.

[0034] There can be exactly two child restraints or the stroller can be configured for exactly two (and no more) child restraints.

[0035] The drive device can be designed in particular as a motor, preferably as an electric motor, possibly as a hub motor, wherein the drive device is designed to drive and / or brake the stroller, in particular the at least one wheel.

[0036] Preferably, a voltage range is provided or defined that specifies the voltage range within which the switching device should be applied for optimal operation. In particular, the stroller does not include a tension pulley for applying a voltage within the voltage range to the switching device.

[0037] This prevents the stroller from moving forward at all or at least inefficiently due to incorrectly adjusted tension. It also helps prevent unwanted snagging of the linkage due to excessive sagging. Furthermore, it makes it more difficult to overstress the linkage, thus preventing damage.

[0038] Preferably, the switching device can also be integrated, in particular in a

[0039] The springs must be elastic in the longitudinal direction of the wheel. This allows for improved power transmission conditions in a wide variety of relative positions between the drive unit and the wheel to be achieved in a particularly simple manner, without the need for manual retensioning or additional components.

[0040] In embodiments, the drive device is arranged in or, in particular, close to (e.g., at a distance of less than 10 cm, less than 5 cm, less than 2 cm, and / or more than 1 mm) the at least one wheel, wherein the drive device can be connected to the at least one wheel, in particular, via a transmission device. The transmission device can be designed as a drive belt, in particular as a toothed belt, or, for example, as a chain. Preferably, the drive device can be arranged in a lower region of the lower frame, in particular between two wheels, for example, between a left and a right rear wheel of the stroller.

[0041] Alternatively, each wheel of the stroller can be assigned its own drive device. The drive device can be arranged such that its axis of rotation is identical to the wheel axis of the at least one wheel or not identical to the wheel axis of the at least one wheel. The drive device is then preferably connected to the at least one wheel via the switching device, preferably such that a rotational frequency of the drive device is higher than a rotational frequency of the at least one wheel. This makes it possible, in particular, to achieve better motor efficiency without the wheel speed becoming too high, which would lead to excessively high travel speeds of the stroller.

[0042] In embodiments, the stroller comprises an actuating device for controlling the at least one drive device. The actuating device is adjustable, with the drive device being controlled based on the position of the actuating device.

[0043] In embodiments, the stroller comprises a control device which is configured to control the drive device depending on a position of the actuating device.

[0044] In embodiments, the stroller comprises an energy storage device, in particular a (rechargeable) battery, wherein the energy storage device is electrically connected to the drive device. The energy storage device (the rechargeable battery) is preferably designed to be removable in order to be able to be charged preferably independently of the other components of the stroller. The energy storage device can be provided in and / or on a wheel axle connecting the two rear wheels and / or in and / or on a cross strut connecting the left and right side struts. A wired and / or wireless connection between the actuating device and the drive device can be established via the control device; for example, the control device can be wired and / or wirelessly connected to the drive device and / or wired and / or wirelessly connected to the actuating device.Preferably, the control device is arranged (directly) adjacent (e.g. at a distance of less than 10 cm or less than 5 cm or less than 2 cm and / or more than 1 mm) to the drive device or the actuating device.

[0045] The drive device can be movably arranged on the frame such that the distance between the drive device and at least one wheel, in particular between the drive device section and the wheel section, can be varied by at least 2 mm or by at least 5 mm or by at least 10 mm, and / or by at most 40 mm or by at most 25 mm or by at most 18 mm. Preferably, the distance between the drive device and at least one wheel can be varied by approximately 7 mm to 15 mm. This is sufficient to ensure not only sufficient belt tension but also simple assembly. At the same time, it keeps the design simple. Preferably, the range in which the distance can be varied is limited by stops.A distance is understood in particular to mean the length of the connecting line between the nearest adjacent points of the spaced elements and / or between their geometric and / or actual centers of gravity.

[0046] The drive device is preferably arranged at a distance from the first axis, in particular at a distance of at least 2 cm, or at least 3 cm, or at least 4 cm, and / or at a distance of at most 8 cm, or at most 7 cm, or at most 6 cm. The drive device can be pivoted about the first axis by an angle of at least 5°, or at least 10°, and / or by a maximum of 25°, or at most 20°.

[0047] Preferably, the drive device can be pivoted about the first axis toward and / or away from at least one wheel. This allows the distance between the drive device and the wheel to be easily varied.

[0048] Preferably, the first axis is parallel to a second axis, with the at least one wheel being (centrically) rotatable about the second axis. This also allows the distance between the drive device and the wheel to be easily varied.

[0049] It can be provided that the drive device is arranged on and / or at a fastening element, wherein the drive device is in particular firmly connected to the fastening element, e.g. by screw and / or rivet and / or adhesive and / or welded connection. The fastening element is preferably at least partially plate-shaped and / or consists at least partially and / or in sections of heat-conducting material (e.g. metal). The fastening element can be connected together with the drive device directly and / or indirectly to the stroller frame (e.g. pivotable about the first axis) and / or thermally connected.

[0050] The transmission device can be designed as (or comprise) a belt or chain. Examples of specific embodiments include roller chains, toothed belts, flat belts, and / or V-belts. This allows torque from the drive device to be easily transmitted to the wheel. When designed as a chain, the transmission element is preferably made of metal, e.g., steel. In the preferred embodiment as a belt, particularly a toothed belt, the transmission element can be made of rubber and / or caoutchouc (e.g., neoprene) and / or plastic (e.g., polyurethane).

[0051] In embodiments, the at least one wheel comprises a wheel section around which the switching device is guided. The wheel section is preferably designed as a sprocket or a pulley, in particular as a toothed pulley. The wheel section can be made of plastic (for example, by injection molding) and / or metal.

[0052] In embodiments, the drive device comprises a drive device section around which the switching device is guided. The drive device section is preferably designed as (or comprises) a sprocket or a pulley, in particular a toothed pulley. The drive device section can preferably be made of metal or (alternatively or additionally) of plastic.

[0053] The switching device can preferably be transferred into a tensioned state, preferably by moving, in particular pivoting, the drive device away from the at least one wheel. In particular, the switching device can be subjected to tension, preferably tensile tension, preferably by pivoting the drive device, which increases the distance between the drive device and the at least one wheel.

[0054] The stroller preferably comprises a fixing device configured to selectively fix the drive device in one of at least two positions relative to the frame or to allow the drive device to be transferred between the at least two positions. In particular, it can be provided that the first position is a proximal position and that the second position is a distal position (in each case relative to the at least one wheel). Preferably, the drive device can assume one or more further positions between the first position and the second position, in particular a continuum of positions, and further preferably, the drive device can be fixed in any position by means of the fixing device. The fixing prevents, at least substantially, any movement of the drive device relative to the frame of the stroller.The fixing device can be frictionally engaged and / or positively engaged. For example, a screw can be provided on the drive element (or a component that moves with the drive element, such as the mounting plate), the end of which opposite the screw head presses against the frame to fix the drive device, or is spaced away from the frame to allow movement (in particular, pivoting) of the drive device. The screw (and / or another screw) can also be provided on the frame and press against the drive device.

[0055] The fixing device can have a guide device or cooperate with such a guide device to guide the movement, in particular the pivoting, of the drive device. The guide device can be, for example, a (straight or curved) elongated hole. The guide device can have stops at its ends to limit the movement. Alternatively, the stops can also be provided independently of a guide device.

[0056] In embodiments, the fixing device can comprise an adjusting means (or an actuation), wherein the fixing device fixes the drive device relative to the frame when the adjusting means is not actuated, and wherein the fixing device allows a transfer of the drive device between the at least two positions when the adjusting means is actuated. The adjusting means can be a handle (rotary handle), in particular for a screw (to enable easier gripping and, if necessary, a leverage effect), and / or one or more handles of a clamp, and / or a knob and / or a similar device to the aforementioned.

[0057] Preferably, the stroller comprises an elastic device, in particular a spring, that urges the drive device away from at least one wheel. In particular, the elastic device urges the drive device toward the second position (toward the distal position). The elastic device can be (or can comprise) a torsion spring and / or a compression spring, for example.

[0058] Preferably, the elastic device applies a force to the drive device that corresponds to the application of a voltage within the voltage range to the switching device. Furthermore, the elastic device applies a force to the drive device, regardless of the position (first position, second position, or intermediate position) of the drive device, that corresponds to the application of a voltage within the voltage range to the switching device. Preferably, only one of the fixing device and the elastic device is provided.

[0070] In the following description, the same reference numbers are used for identical and equivalent parts.

[0071] Figure 1 shows a stroller with two child restraints 103. One or both of the child restraints can be (each) a child seat and / or sports seat – in principle, a carrycot and / or infant carrier can also be provided (in any combination). One of the child restraints is located lower and closer to the front of the stroller frame 100, while the other (compared to the single child restraint) is located higher and closer to the rear of the frame.

[0072] Figure 2 shows a stroller 100 with a pusher 120, a front wheel frame section 130, and a rear wheel frame section 140. The pusher 120 can have a right and a left side strut 121 and can have a handle area 122 designed as a transverse segment with an actuating device 225. On a (respective) inner side of the side struts 121, a rail 102 can be provided, on which a first adapter 170 is displaceably arranged. The (respective) first adapter is located in a lower position in the figure. The front wheel frame section 130 can have (at least) one right and (at least) one left side segment 131 and a transverse segment 132. A second adapter 180 can be provided on the inside of a (respective) side segment 131 of the front wheel frame section 130.

[0073] At a front, lower end of the front wheel frame section 130, two wheels 190 designed as front wheels 191 can be arranged. An upper, rear end of the front wheel frame section can be rotatably connected to a lower, front end of the slider via a first joint 150. The rear wheel frame section 140 can have (at least) one right and (at least) one left side segment 141 and one transverse segment 142 and can be rotatably connected to the front wheel frame section 130 at its front, upper end via a second joint 160. Wheels 190 designed as rear wheels 192 can be arranged at a lower, rear end of the rear wheel frame section, wherein each of the rear wheels 192 can be driven by a drive device 209 designed as a motor. An energy storage device 220, preferably designed as a battery, can be arranged on the transverse segment 142.

[0074] Figure 3 shows the pusher section 120 of a stroller 100, in particular its handle area 122. An interface device 410, in particular comprising or formed from an actuator 226 and a release device 450, can be arranged in the handle area 122. The release device 450 can comprise a button (not shown in detail) and one or more indicators (which can include, for example, lighting devices such as LEDs).

[0075] Figure 4 shows sections of the side segments 141 of the rear wheel frame section 140 of a stroller according to the invention. The side segments 141 can be connected by a transverse segment 142, wherein an energy storage device 220 can be arranged on the transverse segment 142. At the lower end of the side segments, individual components of the rear wheels 192 (not shown in full) can be seen, as well as the drive device 209 designed as a motor. The drive device 209 can comprise a housing 213 and can be arranged on a fastening element 214, in particular fastened thereto. The fastening element 214 can be fastened to the side segment 141 via a connecting piece 512 and can be pivotally connected to it via a (first) axis 215. In a lower region of the fastening element 214, a fixing device 480 can be provided, which preferably comprises a screw 481 and a guide device 482.

[0076] Figure 5 shows sections of the side segments 141 of the rear wheel frame section 140 of a stroller according to the invention. The side segments 141 can be connected by a transverse segment 142, wherein an energy storage device 220 can be arranged on the transverse segment 142. At the lower end of the side segments, individual components of the rear wheels 192 (not shown in full) can be seen, in particular a wheel section 194 designed as a toothed belt pulley. The wheel section 194 can be driven by a drive device section 216 (designed as a toothed belt pulley) via a transmission device 217 (in the form of a belt). The transmission device 217 is partially hidden in the area of ​​the drive device section 216. An internal toothing of the transmission device 217 is not shown. A second axis 193 (wheel axis) is preferably parallel to the first axis 215.

[0077] In general, a drive device axis (without reference number) about which the drive device section 216 rotates, in particular the rotor of the drive device 209 located on the back of the connecting piece 512 in the embodiment of the present figure, can also be arranged parallel to the first and / or second axis.

[0078] In general, the stroller 100 may have a parking brake 101.

[0079] Figure 6 shows a wheel 190 and a drive mechanism 209 of a stroller, with a cover removed. The drive mechanism 209 is partially concealed or enclosed; a drive mechanism section 216 and a switching mechanism 217 can be seen. The switching mechanism 217 can rotate around the drive mechanism section 216 and a wheel section 194.

[0080] Figure 7 shows the wheel 190 of Figure 6 from a roughly opposite direction, with further covers hidden. Only a small section of the switching device 217 is visible. Instead, the screw 481 and guide device 482 of the locking device 480 are visible, as is the parking brake 101, which in the present embodiment is pivotable about the second axis 193.

[0081] Figure 8 shows a highly schematic representation of a switching device 217 that can be guided around a wheel section 194 and a drive device section 216. The drive device 209 is mounted on a fastening element 214 pivotable about a first axis 215 and can be secured in one position with a fixing device 480. In the illustrated embodiment, the drive device 209 (and thus also the drive device section 216) is too close to the wheel 190 (and thus also to the wheel section 194), so that the switching device 217 is not sufficiently tensioned.

[0082] Figure 9 corresponds to Figure 8, but now with a greater distance between drive device 209 and wheel 190, so that the switching device 217 is under tension and lies closely against wheel section 194 and drive device section 216.

[0083] Figure 10 shows a highly schematic representation of a switching device 217, which is guided around a wheel section 194 and a drive device section 216. The drive device 209 is mounted on a fastening element 214 pivotable about a first axis 215, and an elastic device 219, here designed as a torsion spring, urges the fastening element 214 with the drive device 209 away from the wheel 190.

[0084] In Figures 8 to 10, the wheel portion 194 has a smaller diameter than the drive device portion 216. In practice, this may be the other way around to allow higher engine speeds.

[0085] At this point, it should be noted that all parts described above, viewed individually and in any combination, particularly the details shown in the drawings, are claimed as essential to the invention. Modifications to these are familiar to those skilled in the art.

[0086] Furthermore, it is pointed out that the broadest possible scope of protection is sought. In this respect, the disclosure contained in the claims can also be clarified by features that are described with further features (even without these further features being mandatory). It is explicitly pointed out that parentheses and the term "in particular" are intended to emphasize the optionality of features in the respective context (which does not mean, conversely, that without such identification, a feature is to be considered mandatory in the corresponding context). The term "element / element" is preferably intended to identify a coherent structure (or assembly), which in turn can be connected to at least one other structure (to form a possibly integral and / or inherently immobile overall structure) or can be delimited from all other structures.
