Definitions
- the present invention relates to a set of modular elements allowing, depending on the assembly configuration of the elements, either to constitute a stroller, or to obtain a wheeled vehicle capable of being ridden by a child.
- An additional objective of the invention is to provide a set of elements such as aforementioned, allowing the stroller to be folded into a reduced volume in order to facilitate the storage or transport of this assembly when not in use.
- An additional objective of the invention is to provide a set of elements such as those mentioned above, making it possible to obtain the stability required for the stroller without limiting the possibilities of use of the machine by the child. nor increase the volume occupied by the set of elements in the folded state.
- the set of elements according to the invention comprises:
- this vehicle comprising a body capable of being ridden by a child, this body comprising, at its front part, a grip handle capable of being grasped by a child riding said body, and comprising means for mounting the driving handle on this body;
- the seat is dimensioned so as to, in said unfolded position, rest on said grip handle, thus allowing stable support of the seat by this grip handle; in said folded state, the seat allows the part of the machine intended to be ridden by a child to be released.
- the wheeled machine is integrated into the stroller as the rolling chassis of this stroller. It follows that a parent does not, when transporting a child in the stroller and also wishes to have a wheeled vehicle for the child's amusement, have to transport this vehicle with wheels at extra cost.
- the seat In its unfolded position, the seat is capable of receiving the child in a stable and secure manner; in the folding position of this seat, the child can straddle the machine and be driven by the parent by means of said driving handle.
- Said seat/driving handle sub-assembly may not be removable relative to said body of the machine; However, this would result in the disadvantage that the child would only be able to have fun with said seat/driving handle sub-assembly mounted on said wheeled machine, therefore with a certain amount of space and a certain weight; therefore, preferably, said means for mounting the driving handle on the body of the machine are designed so as to allow removable mounting of said seat/driving handle sub-assembly.
- This subassembly can therefore be dismantled in relation to the wheeled machine, thus allowing the child to have a machine comprising only said body, the wheels and said grip handle.
- the seat could simply rest on said grip handle; preferably, however, to prevent any risk of untimely movement of the seat in certain situations, in particular in the event of the stroller overturning, the set of elements comprises means for connecting the seat to the grip handle.
- the grip handle is in the shape of a "T”, that is to say it has an upper bar forming the equivalent of a “handlebar”, this upper bar comprising first connecting means at its ends, and
- the seat has lateral parts capable of covering these ends of the upper bar and presents, at the level of these lateral parts, second connecting means capable of coming into engagement with said first connecting means to achieve the connection of the 'seat to the grab handle.
- the first connecting means in question can for example be constituted by holes having screw threads arranged in said ends of the upper bar, and the second connecting means are then constituted by screws capable of passing through said lateral parts of the seat and to be screwed into said holes.
- said driving handle has lower parts connected to upper parts by pivoting connections, these pivoting connections allowing the driving handle to be placed either in an unfolded state, for driving the stroller, or in a state of folding, in which said lower and upper parts are placed in a position close to the body of the wheeled machine, along the lateral sides of this body;
- the seat is pivotally connected to said pivoting connections via mounting foils which offset the plane formed by the seat relative to the pivot axes formed by the pivoting connections, this offset allowing the seat to come over the body of the machine in said folded state.
- the set of elements according to the invention can thus adopt a reduced volume in this folded position, allowing its easy storage or transport.
- said gripping handle is able to be placed in two vertically stepped positions, namely a lowered position, making it possible to reduce the bulk of the set of elements when not in use, and a raised position, making it possible to position the grab handle at a height suitable for the child riding the machine to grab this handle.
- said gripping handle comprises a column forming a tubular portion while the body of the machine forms a tubular extension receiving this tubular portion in a telescopic manner, and comprises immobilization means making it possible to immobilize said tubular portion and said tubular extension relative to each other in one or the other of the two aforementioned positions of the gripping handle.
- These immobilization means may in particular comprise respective holes of said tubular portion and of said tubular extension, coming into coincidence with one another in one and the other of said positions, and a locking pin suitable for to be engaged in these holes, this nipple being associated with a spring allowing its mobility between an engagement position in these holes and a release position relative to these holes.
- the grip handle is mounted pivoting, in particular at its base, on the body of the machine, so as to be able to pivot between an unfolding position, in which it is erect and able to be grasped by a child riding the machine, and a position folding, in which it is lowered so as to be located near the front of the body of the machine, fixing means being provided to maintain the handle at least in said unfolding position.
- the body of the machine can be divided transversely into two parts, namely a front part and a rear part, these parts being connected to each other in a pivoting manner, this pivoting allowing mobility of said rear part relative to the front part between an unfolded position of use, in which the rear part extends away from said front part, and a folded storage position, in which the rear part is folded towards the front part along the lower side of this front part.
- the set of elements comprises means for positioning the rear wheels of the machine in two spacing positions, namely a position of greatest spacing, which is adopted in the "stroller" configuration of said set of elements, and a position of smaller spacing, which is adopted when the wheeled machine is used as such or when the set of elements is in the state of folding.
- the driving handle comprises, at its lower part and on its rear side, a strut connected to a locking block, this block being intended to come into engagement with the body of the machine and allowing thus locking the handle on the body, in the unfolding state of this handle.

- Figure 18 is a side view of the set of elements according to another embodiment, showing an unfolded position of this set in solid lines and a partially folded position of this set in broken lines.
- Figures 1 and 2 represent a set of modular elements allowing, in the assembly configuration of the elements shown by these figures, to constitute a stroller 2, and, in another configuration shown by Figures 5 and 6, to obtain a wheeled machine 3 capable of being ridden by a child.
- the set of elements comprises (i) a subassembly 5, 6, formed by a stroller seat 5 and a stroller driving handle 6, and (ii) the wheeled machine 3, which constitutes the rolling chassis of the stroller 2.
- the seat 5 of the stroller 2 comprises a seat 10 and a backrest 11, as well as, in the example shown, a front part 12 forming a footrest, and a sunshade hood 13.
- these different seat parts 10 to 12 include assembled canvas pieces, carried by support structures 15, 25, 26, these pieces of canvas being erased in Figures 3 and 4 in order to make these support structures visible.
- the sunshade hood 13 is also erased in these Figures 3 and 4.
- the seat 10 comprises, in addition to the piece of canvas, a plate 15 having two side cheeks on its rear part, by which the seat 10 is pivotally mounted on the driving handle 6.
- This pivoting assembly is produced at the level of pivoting connections 16 which connect lower parts 6a of the side branches of the handle 6 to upper parts 6b of these same branches.
- One of the connections 16 is more particularly visible in section in Figure 8; it appears that each side cheek 15a of the plate 15 is connected to one of the two parts forming the connection 16 by means of a screw 17, in a pivoting manner.
- the side cheeks 15a make it possible to offset the seat plane formed by the plate 15 relative to the pivot axes formed by the connections 16; as is visible in Figure 7, in the folded position, the lower parts 6a and upper 6b extend along the lateral sides of the body 21 of the machine 3, with the connections 16 located near the front wheels of the 'engine 3; said offset allows, in this folded state, the seat 10 to come over the body 21 of the machine 3.
- the set of elements thus has a reduced footprint.
- the backrest 11 in addition to the piece of canvas which is specific to it, includes a hoop 25 forming a support frame for this piece of canvas.
- the arch 25 is mounted on the connection 16 by the same screw 17 as that used for mounting the cheek 15a of the plate 15.
- the front part 12 which forms a footrest also includes, in addition to the piece of canvas which is specific to it, a hoop 26 for supporting this piece of canvas.
- This arch 12 is pivotally mounted on the front of the seat 10, this pivoting being, in the example shown, carried out by means of rounded parts 26a formed at the ends of the arch 26, which are pierced with shoulder holes, these holes receiving the screws 22 as shown in Figure 9.
- the sunshade hood 13 is, for its part, of the classic type and is not part of the invention; it therefore does not need to be particularly described.
- This handle 6 in addition to the aforementioned lower parts 6a and upper parts 6b, comprises an upper arch 6c connected to said upper parts 6b by assembly connections 30 similar to the connections 16.
- the handle 6 thus has the shape of a handle elongated, forming an upper arch and two lateral branches.
- each connection 16 is formed by two parts connected by a screw 31, these parts being respectively connected to the respective parts 6a, 6b; one of the two parts (the one on the left in Figure 8) has a projecting prismatic part 32 at the level of its assembly face to the other part, which is able to be received in an adjusted manner in a cavity of corresponding shape that said other piece presents.
- the prismatic part 32 is kept engaged in said cavity, which ensures that the two parts are immobilized in rotation. forming the connection 16 relative to each other.
- This pivoting locking position corresponds to the maintenance of the upper part 6b in the extension of the corresponding lower part 6a, therefore in the unfolding state of the handle 6.
- said prismatic part 32 can be released from said cavity, which allows the upper part 6b to pivot relative to the lower part 6a, making it possible to fold the handle 6.
- the handle 6 is removably mounted on the body 21 of the machine 3, so that said subassembly 5, 6 can be removed from this machine .
- the machine 3 can then be used for the amusement of a child, the latter coming to ride the body 21 by sitting on a saddle 21a formed on the upper part of this body 21, and coming to grasp the upper bar 20a of the handle 20.
- each link 35 comprises a base 36 receiving the lower part 6a, this base being pivotally mounted in a bearing formed by the body 21 and being retained on this body by means of a screw 37.
- the lower part 6a is received in an adjusted manner in a corresponding hole formed by the base 36, and is retained in this hole by means of a movable pin 38 associated with a leaf spring 39.
- This pin 38 passes through a hole in the part 6a and a hole in the base 36 to ensure retention of the part 6a on the base 36, and is able to be pressed against the elastic force of the spring 39 so as to release the part 6a relative to the base 36.
- the handle 6 further presents, at its lower part and on its rear side, a strut 40 connected to a locking block 41 making it possible to lock the handle 6 on the body 21, in the unfolded state of this handle.
- this block 41 engages between two parallel branches that form the rear part of the body 21 and is engaged with these two branches.
- Block 41 is more particularly visible in Figures 11 and 12; as appears in these figures, the block 41 is in the form of a housing connected to the two lateral parts 40a of the strut and has a push button 42 on its upper part, capable of being pressed into the housing by a user , this push button 42 being associated with two springs 43 which return it to the extended position.
- the push button 42 forms two studs 42a whose free ends have inclined surfaces so as to form actuation ramps. Each of these free ends is located near an actuating rim presented by a corresponding sliding latch 44, this latch 44 having one end which passes through the corresponding side wall of the housing and which forms a locking pin. This nipple is capable of being received in a locking cavity 45 corresponding arranged in one of the aforementioned parallel branches 21b formed by the rear part of the body 21. The two latches 44 are returned to the locking position by a spring 46 extending between them.
- the grip handle 20 is able to be placed in two vertically stepped positions, namely a lowered position visible in Figure 7, for storage, and a raised position , visible in Figure 6, allowing the handle 20 to be placed at the appropriate height for its grasp by a child riding the body 21 of the machine 3.
- the lowered position makes it possible to reduce the bulk of the set of elements in the storage or transport position shown in Figure 7.
- the handle 20 comprises a column 20b whose lower part forms a tubular portion 20b 1, and the body 21 forms a tubular extension 21c in which said portion 20b is telescopically received 1.
- the latter and the extension 21c comprise respective holes which coincide with each other in one and the other of said lowered and raised positions of the handle 20.
- a locking pin 50 is able to be engaged in these holes, this pin being associated with a leaf spring 51 allowing the mobility of the pin 50 between a position of engagement in the holes in coincidence, allowing the blocking of the handle 20 relative to the body 21, and a position of clearance of the pin 50 relative to these same holes, allowing telescopic sliding of the column 20b relative to the extension 21c.
- Figures 1 to 4 are capable of being placed in two spacing positions, namely a position of greater spacing, visible in Figures 1 to 4, which is adopted in the "stroller" configuration, and a position of smaller spacing, visible in Figures 6 and 7, which is adopted when the machine 3 is used by the child or when the set of elements is in the folded state.
- the greater spacing of the rear wheels makes it possible to give great stability to the stroller 2, while the smaller spacing of these same wheels allows the child to use the machine 3 in a way which is not constrained by excessive spacing of the rear wheels, and allows compact folding of said set of elements.
- This spacing is controlled by means of two cursor buttons 52 located on the rear part of the body 21, visible in Figures 2 and 4.
- Figures 14 to 17 show more particularly the mechanisms of which the buttons 52 are part. As visible in Figures 16 and 17, these buttons 52 are integral with locking rods 55; it appears in these figures and in Figures 14 and 15 that ends in the form of locking pins of these rods 55 are able to come into engagement in corresponding receiving cavities arranged in a bar 56 and a tube 57 engaged telescopically one in the other, this bar 56 and this tube 57 forming the axle of the rear wheels 60 of the machine 3.
- the locking rods 55 are biased by springs 58 in locking positions corresponding to the engagement of said pins in said receiving cavities.
- Figure 18 is a view of the set of elements according to another embodiment, in which the body of the machine 3 is divided transversely into two parts 3a, 3b, namely a front part 3a and a rear part 3b, these parts being connected to each other in a pivoting manner, by a connection 65 forming a pivot axis hinge transverse to the body of the machine 3.
- the pivoting made possible by this connection allows mobility Of the game rear 3b relative to the front part 3 a between an unfolded position of use, shown in solid lines, in which the rear part 3b extends away from said front part 3 a, and a partially folded, storage position, shown in broken lines, in which the rear part 3b is folded towards the front part 3a along the lower side of this front part 3a.
- the folded position shown in broken lines is a position of complete folding of part 3b but is a partial folding position in the sense that the driving handle, the grip handle and the seat, as shown, are not folded .
- the invention provides a set of modular elements which overcomes the disadvantages of the prior technique by making it possible to move from the "stroller” configuration to the "machine” configuration simply and quickly, by allowing the stroller to be folded into a reduced volume in order to facilitate the storage or transport of this assembly when not in use, and by allowing the stability required for the stroller to be obtained without limiting the possibilities of use of the stroller machine by the child nor increase the volume occupied by the set of elements in the folded state.
