- Strollers are known that can be connected to a bicycle.
- Such strollers are for example described in DE 299 19 159 and include, in this case, a handlebar which can be tilted forward to take a horizontal position when it is intended to be connected to a bicycle.
- the transition to position "trailer” is complex, and requires in particular the disassembly of the front wheels and the handle, to replace it with a drawbar.
- the suitcase acting as a child seat must also be disassembled and reassembled.
- the invention particularly aims to overcome these disadvantages of the prior art.
- an object of the invention is to provide a stroller that can pass simply and easily from a stroller position to a trailer position.
- Another object of the invention is, according to at least one embodiment, to provide such a stroller whose use in its trailer position is particularly easy and comfortable for the user.
- Another object of the invention is, according to at least one embodiment, to provide a stroller convertible into a trailer without the need to remove the child during this change of position and without causing discomfort or risk to the child. child.
- Yet another object of the invention is, according to at least one embodiment, to provide such a stroller that provides a good level of comfort for the child transported, both in the stroller position in the trailer position.
- An object of the invention is, according to at least one embodiment, to provide such a stroller that is easy to manufacture, and low cost.
- a stroller for children convertible into a bicycle trailer, comprising a frame carrying at least one seat and handlebars.
- said handlebar is articulated with respect to said frame and able to switch between:
- a "stroller” position in which an end portion, referred to as a gripping zone, of said handlebar makes it possible to guide and move said stroller, and a “trailer” position, in which said gripping zone of the handlebar can be secured to a bicycle .
- the stroller comprises means for retracting a front wheel or wheels, controlled by the tilting of said handlebar, the said front wheel or wheels being in a functional position, in contact with the ground, in the "stroller” position, and in a retracted position, not interacting with the ground in "trailer” position.
- gripping zone the end portion of the handlebar, here called gripping zone, in both positions.
- the "stroller” position it classically forms the handle or handles, that is to say the area where the user puts his hands to push and guide the stroller.
- this same gripping zone constitutes the element of solidarity to the bicycle.
- position "stroller” means a position of the stroller adapted to be connected to the bicycle.
- the conversion implemented according to your invention makes it possible to maintain the orientation of the child with regard to the displacement.
- the child will always be placed in the direction of walking.
- the conversion of the stroller into a trailer (or vice versa) does not introduce a change of orientation of the child which gives him comfort.
- the invention avoids, since everything is done by a simple tilting of the handlebars, any disassembly or adaptation of the chassis to move to the "trailer” position. In particular, it is not necessary to disassemble the front wheels and / or the handlebar to move to the "trailer" position.
- the change of position may, according to the invention, be operated in the presence of the child, a saving of time is obtained to perform such a conversion. It is thus possible, for example, to use the stroller in the "trailer” position to take the child to the park, by bike, park the bike and continue the walk in the park (or indoors, for example). example in a trade), in "stroller" position.
- the stroller convertible into a bicycle trailer according to the invention is extremely practical, because the change of position is easy and fast.
- the stroller according to the invention may comprise one or more removable seats or not, if necessary independent of one another, allowing the transport of one or two or more children, to form a stroller double (two children) or even a triple stroller (three children).
- the stroller can be a double stroller / trailer to install and carry two children side by side (in this case the door frame two adjacent seats arranged in the same plane or a double seat) or one behind the other (in this case the frame has two seats arranged one behind the other).
- the seat is chosen from a plurality of different seats, adapted to different ages of the child or allowing different positions: a seat, sometimes called “hammock”, foldable or rigid, a rigid seat that can also serve as a car seat, a basket to carry a baby lying down, etc.
- the seat or seats can be removable and / or independent, for example to allow to tilt the back of a seat without tilting the other seat.
- the front wheel or wheels are moved under said at least one seat carried by the frame.
- the displacement of the wheels under the seat limits the size of the team and prevents the child or the cyclist from getting injured during handling of the trailer.
- the front wheel or wheels are folded flat under the seat.
- a housing specifically designed to accommodate the front wheel or wheels is provided under the seat so that the front wheel or wheels are completely or partially integrated by nesting under the seat.
- the front wheel or wheels are carried by two shafts before extending in the extension of two amounts of said handlebar, the front shafts simultaneously swinging with said uprights.
- the front wheel or wheels are connected to the handlebar so that the pivoting of the handlebar necessarily entails the retraction of the wheel or wheels.
- It may in particular be a wheel or a single wheel block.
- a front stretcher and an amount form a single piece.
- the frame, or said a seat carried by said frame carries two nodes of articulation, allowing the tilting.
- the implementation of the tilting is simple because the hinge nodes provide tilting fluidity to limit jolts that may occur during the change of position.
- At least one of the knots carries blocking means, able to hold the handlebars in the "stroller” position and / or in said "trailer” position, and unlocking means, for releasing said locking means to tilt said handlebar.
- the stroller comprises, in the vicinity of the said front wheel or wheels, a first locking element, able to cooperate respectively with:
- a third complementary locking element mounted in the vicinity of the lower part of the backrest (94) of said seat.

- Figure 6 shows the stroller according to the invention in the trailer position attached to a bicycle
- FIGS. 7A to 7D represent different steps relating to the attachment of the stroller in the trailer position to a bicycle
- Figure 8 illustrates a variant of the attachment means to a bicycle
- Figure 9 shows the stroller in the folded position according to one embodiment of the invention.
- Figures 10A and 10B schematically illustrate a variant of the blocking of the stroller of the invention in the two positions.
- the general principle of the invention is based on the tilting of the handlebar of the stroller, which allows on the one hand the passage of the stroller from the "stroller” position in the “trailer” position or vice versa, and secondly the retraction of the front wheels of the stroller, in the "trailer” position, or their deployment in the "stroller” position.
- the stroller comprises a single seat (embodiment described below)
- the upper end of the handlebar in “stroller” position the upper end of the handlebar is placed at the rear of the seat carrying the child and the front wheel or wheels are deployed (in contact with the ground), while in “trailer” position the handlebar is tilted relative to the seat, or chassis, so that its upper end can be attached to the back of a bike.
- the tilting of the handlebar automatically actuates the means of retraction of the front wheel or wheels.
- Figure 1A shows a perspective view of the stroller in "stroller” position according to one embodiment of the invention, in a conventional configuration with three wheels (or blocks of wheels). It is clear that, in the context of the invention, the stroller may also have four wheels.
- the stroller comprises a single seat. It should be noted that the stroller may also include several removable and independent seats allowing the transport of several children (for example two or three) side by side or one behind the other.
- the base of this stroller is formed of a frame 1, which for example implements tubular elements.
- the seat 4 functionally provides part of the functions of the chassis, in particular by directly bearing the rear legs 14 and the hinge nodes 12.
- the chassis, and more precisely the seat 4 carries on each side a hinge node 12 for tilting a handlebar 11 between the "stroller" position shown in Figure 1A, and the trailer position. illustrated in Figure 1B.
- the chassis further comprises two rear legs 14 each carrying a rear wheel 21, called main wheels, which extends substantially perpendicular to the direction of travel of the stroller and therefore the direction of the handlebar 11.
- the rear legs 14 may for example be formed in a single piece, substantially forming an open U, whose base is secured to the seat by any suitable means.
- the main wheels 21 are advantageously large diameter wheels, for example 16 inches in order to facilitate obstacle crossings, such as sidewalks, steps, holes, bumps, passages in the sand or in gravel. Such wheels are further adapted for use towed by a bicycle.
- the rear legs 14 are inclined rearward, so as to deport rearwardly the axis of the rear wheels 21, which are thus in the "stroller" position, substantially in the same vertical plane as the upper end of the handlebars.
- the frame may also comprise damping means, which may be constituted, for example, by a rubber member or by a spring. They thus ensure the suspension of the stroller both in its "stroller” position as in its "trailer” position.
- damping means may for example be placed at the wheels and / or the connection between the rear legs and the seat.
- the handlebar 11 is formed of two uprights 110 disposed on either side of the stroller and connected to the hinge nodes 12 so as to frame the seat 4 which carries the child.
- the two uprights 110 are extended by a cross member corresponding to a gripping zone 16.
- the handlebar therefore has a generally U-shaped shape, and the gripping zone 16 corresponds to the base of this U.
- the cross member 16 comprises, in this embodiment, two sections 161 and 162 forming handles, connected by a third central section 163 of smaller diameter than that of the sections 161 and 162. This third section 163 is used for fixing in position "trailer To the bike.
- the central section 163 is adapted to facilitate connection to a bicycle, and has for example a light or a blind hole drilled transversely and perpendicularly to the direction of movement of the stroller in "trailer" position.
- the section 163 is here drilled vertically relative to the horizontal position of the handlebar 11.
- handlebars and as a result of connection with a bicycle, can be envisaged.
- the connected handlebar is replaced by two unlatched pushers, each equipped with a handle forming a gripping zone, in the "stroller” position.
- one or both pushers are secured to the bike, at the handles, in the "trailer” position.
- gripping area 16 that is to say the upper end of the handlebar 11 in the "stroller” position, which provides a dual function, on the one hand handle (more generally of area where the user puts the hand or hands to push and direct the stroller), in the "stroller” position and secondly zone of attachment with the bike, in the "trailer” position.
- the uprights 110 may also be adjustable in length and / or height, for example by means of a telescopic adjustment.
- a front base also called stretcher 3 is attached to each hinge node 12.
- a front wheel 31, or secondary wheel, is mounted at the lower end of these front legs 3 which, in the illustrated embodiment, meet and are formed in the same room 5.
- the axis of the front wheel is fixed or pivotably mounted relative to a vertical axis. It can also be selectively fixed or mobile. In the latter case, two fixed positions can be provided, one for the "stroller” position and the other for the "trailer” position, taken automatically during the switchover.
- the front wheel (31) can be replaced by a wheel block, comprising two adjacent wheels.
- the uprights 110 of the handlebar are extended by the front legs 3, which are formed in the same room. In other embodiments, it may of course be distinct elements, connected at the knot nodes 12.
- the seat corresponds, in this embodiment, to a seat 4 wraparound, equipped with side elements for good protection of the child.
- This is a large seat, suitable for transporting a child up to 4 years, for example, or more. Reducers, comfort elements, other seats allowing the transport of several children, ... can of course be provided.
- the hammock forms an element of the frame, and carries the rear legs and knuckle nodes.
- the hammock can be removable and be replaced for example by a hull or a nacelle.
- conventional means such as those used by the Applicant and known under the trademark "Moduloclip” may be used to secure the hammock, or any other element, to the frame.
- This hammock, hull or pod can be provided with a safety harness to keep the child in the seat thus formed.
- a seatbelt (not shown) may also be integrated when the child is older.
- a removable protective hood against the weather can also be secured to / detached from the stroller.
- Figures 2A, 3A, 4A and 5A respectively show the side, front, back and top views of the stroller in "stroller” position.
- the handlebar 11 is used to guide and move the stroller, including pushing or pulling.
- the front wheel or wheels are in direct contact with the ground.
- Figure 1B shows a perspective view of the stroller in "trailer” position after tilting of the handlebar 11 with respect to the "stroller” position of Figure 1A.
- the stroller in the "trailer” position comprises a single seat.
- the stroller may also include several removable and independent seats allowing the transport of at least several children (for example two or three) side by side and / or one behind the other.
- the front wheel 31 is for example moved under the seat 4 so that the stroller in the trailer position or coupling, has only two wheels in contact with the ground, as illustrated in particular more precisely by the views of side and back of Figures 2B and 4B.
- the retraction B2 of the front wheels under the seat is automatic and controlled by the tilting of the handlebar 11. No disassembly operation of the handlebars or the front wheels is therefore necessary to connect the stroller to the bike.
- the retracted position of the front wheel or wheels is secured by locking means (not shown).
- the front wheel or wheels 31 can be pivotally movable, it can be provided that the passage in the "trailer" position causes an automatic return to the fixed position, in particular for the wheel to enter a housing provided for this purpose under the seat.
- the front wheel 31 automatically takes another fixed position, for example to lie flat under the seat.
- the child, present in the seat can remain in the seat during the transition from the "stroller” position to the "trailer” position.
- the dimensions of the front legs 3 and the front wheel 31 are, according to this embodiment, chosen so that the front wheel 31 remains in contact with the ground during a portion of the pivot, without the inclination the seat is heavily modified.
- the length of the front legs 3 carrying the front wheel or wheels may represent 25 to 35% of the length of the uprights 110 of the handlebar 11.
- Such a proportion between the uprights 110 and the legs (or stretchers) 3 allows in particular to maintain balance and stability when changing position stroller to trailer or vice versa.
- Conversion into a trailer (and conversely) according to the invention is convenient, fast and secure for the child who does not need to be detached, worn and removed from the seat, placed on the road and therefore exposed to risks of it while the cyclist operates the change of position of the stroller, then carried forward and re-attached in the stroller once converted into a trailer.
- the cyclist responsible for the child protects his child from the risks of the road and protects himself physically by avoiding the actions related to the movement of the child during the change of position of strollers convertible into a trailer of the prior art .
- the balance and comfort of the child is at least partly maintained during the change of position because the stability provided by the tilted position of the handlebar to be attached to the bike in the trailer position is substituted for the stability provided by the or the front wheels in stroller position. It is possible, in addition, to provide a crutch, to keep the stroller in the "trailer" position in the absence of a bicycle.
- the front wheel 31 has thus been retracted, by pivoting about an axis either upwards, or preferentially under the seat 4.
- the handlebar can take an intermediate position, storage, for example when it reaches a vertical position, towards the sky, and substantially parallel to the back of the seat of the child during his tilt to the before the seat to move to "trailer" position, the secondary wheel or wheels then already retracted.
- the knuckle nodes allow a storage position in which the handlebar is in the "stroller” position and the front wheel is retracted under the seat.
- Figure 4B which illustrates the stroller seen from behind, in the "trailer” position, the front wheel or wheels are retracted under the seat 4 of the seat, between the two rear wheels.
- a housing within the seat or under it so that once retracted the (or) secondary wheel is at least partially hidden in this housing. It can be equipped with bosses rubbing against the wheel, and opposing its rotation.
- the tilting of the handlebar causes a simultaneous modification of the height of the seat 4 relative to the ground to adjust the height of the seat of the child so that it see for example above the rear wheel of the bike to which it is attached.
- the hinge node 12 allows the tilting of the handlebar between the "stroller” position, in other words when the handlebar is located behind the seat with regard to the direction of movement of the stroller, and the "trailer” position when the handlebars, after passing over the seat and the child's head, extend forward in the direction of travel of the stroller towed by a bicycle.
- the hinge node 12 comprises a fixed part relative to the chassis or, in the embodiment illustrated with respect to the seat, and a part movable in rotation relative to this fixed part, carrying the amounts of the handlebars .
- Two stops are provided on the fixed part, defining stopping positions of the tilting, respectively corresponding to the "stroller” position and the “trailer” position.
- these stops can be equipped with damping elements.
- locking means of each of these positions may be provided, for example in the form of a dog or a pin cooperating with a corresponding light, at one of the nodes.
- a central button for example, mounted on a spring, allows to separate the dog or the pin, and tilt the handlebars. In the absence of action on the button, the spring blocks all and prevents tipping.
- This approach makes it possible, if necessary, to define a storage position, as indicated above, and, if necessary, several "stroller” positions (for example to offer several handlebar heights) and / or several positions “trailer” (for example to adapt to several heights or bike attachment modes).
- the unlocking can also be controlled remotely, as illustrated in the embodiment of FIG. 9.
- the unlocking control 101 is placed on the top of the seat back 4, and controls the unlocking of the knot 12 via a transmission, such as a cable 102 (which can of course be hidden in the seat). This makes it easier to control the movement of the handlebar, a hand on the seat controlling the unlocking and a hand on the handlebar ensuring the movement thereof.
- the locking means may be located in different locations, depending on the position of the handlebar.
- a first locking element 91 is provided in the vicinity of the front wheel 31, for example on the portion 33 connecting the two front legs 3 ( Figure 3A) and carrying the wheel support 34, or on the wheel support 34, or on one of (or the two) front legs 3, a first locking element 91 is provided.
- This first locking element 91 shown schematically in FIGS. 10A and 10B, can cooperate with two complementary locking elements 92, 93, which are structurally identical and also schematically represented in FIGS. 10A and 10B, according to the position of the handlebar:
- the first element 91 may for example be a hook, and the second and third elements 92, 23 of the clamps adapted to maintain this hook.
- Many known locking variants can of course be easily adapted.
- the locking is automatic, that is to say that, at the end of the tilting stroke of the handlebar, the first locking element 91 comes into contact with the second or third locking elements 92, 93, and s engages in this one to take a locked state, without any other action of the user.
- the lock control 110 placed at the rear or on one side of the backrest, acts simultaneously, in this embodiment, on two transmission cables 96 and 97 which respectively control the second and the third locking elements 92, 93.
- Figure 6 illustrates the stroller 61 of the invention, secured to a bicycle 62.
- FIGS. 7A to 7D The attachment means of the stroller in "trailer" position to the bicycle are illustrated in particular by FIGS. 7A to 7D.
- securing means 71 are secured for example to the collar of the rod of the bicycle seat, by means of a clamping screw 711. These fastening means are for example intended to remain permanently on the bike of the user.
- These fastening means comprise, in the illustrated embodiment, a ball 712 so as to allow free movement of the hitch relative to the bike during movement such as turns, obstacle crossings or unevenness.
- the handlebar 11 of the stroller tilted to the "trailer" position is fixed to the securing means secured to the collar of the rod of the bicycle seat, by passing a finger 714 secured to the ball joint through the light of the central section 163 handlebar previously detailed, then folding a closure valve 713 can be mounted elastically, and / or allowing manual tightening thereof in the closed position to prevent any detachment of the handlebar of the seat of the bicycle.
- the fastening means are for example universal fastening means suitable for any bicycle.
- the fastening means are for example universal fastening means suitable for any bicycle.
- the finger 714 can be replaced by a ball 81, cooperating with a complementary concave shape 82 provided for this purpose on the gripping area 16. This approach also allows the bicycle to lean, the two rear wheels of the trailer remaining in contact with the ground.
- the fastening means may further comprise a complementary offset piece, which may be removable, extending in the direction of movement of the bicycle.
- a complementary fastening piece makes it possible to shift towards the rear of the bicycle the hooked point of the handlebar (with respect to the hooking point shown in FIGS. 7A to 7D located near fastening means secured to the collar of the rod of bike saddle).
- the knuckle control and optionally locks in a storage position, by means of locking means, both the handlebar in the vertical position, facing the sky and substantially parallel to the backrest of the child's seat, and also the complete retraction of the front wheel or wheels under or in a seat of the seat.
- a reduction of the handlebar height can be operated in this storage position, in particular by means of 110 telescopic uprights.
- Braking means may also be provided to stop and immobilize the stroller, particularly in the "stroller” position.
- braking activation means may be provided, automatically blocking the rear wheels when the handlebars are tilted for safety and / or the front wheel or wheels in the "trailer” position. It is also possible, in the latter position, braking control means, transferring a brake control of the rear wheel of the bicycle to at least one of the rear wheels of the stroller.
