Description

Title of the invention: Self-locking wheel-blocking device for receiving and holding a wheel of a cycle and installation of cycle parking facilities equipped with such devices. technical field

[0001] The present invention relates to a self-locking wheel-blocking device which allows a wheel of a cycle, in particular a front wheel of the cycle, to be received and held in order to keep said cycle stable without the use of a kickstand and, thus, to prevent said cycle from falling.

[0002] The invention will find its use, for example, in homes, the self-locking wheel chock device being able to be installed in a garage of the home, or on a private or public road, in a bicycle parking area. To this end, the invention will also relate to a bicycle parking facility equipped with such self-locking wheel chocks. State of the art

[0003] Wheel-blocking devices are known which allow a front wheel of a cycle to be received and held in order to keep it balanced and, in some cases, to ensure a locking of the front wheel on said wheel-blocking device.

[0004] In this respect, the applicant is aware of the prior securities published under the following numbers: US3785517; FR2414437; US5301817; WO9511154; GB2303109; WO9638336; FR2763909; US6241104; KR100520742; US6095746; US6640979; US2003160423; GB2394928; FR2860485; US7150359; JP2006062517; US2007068881; JP2007118642; US2009001031; JP2009083738; WO2009066110; CA2729670; US2011233154; WO2011141694; WO2013164501; ES2550531; WO2016005828; US2018334073; US2019218809; CN108756350; and US2020331551.

[0005] Among these aforementioned prior art, the international patent application WO9511154 This describes a self-locking wheel clamping device comprising a first part, forming a shoe, designed to receive the front wheel and to pivot from a first position for receiving the wheel to a second position for locking the wheel in said first part. The transition from the first position to the second position is achieved by means of a mechanism equipped with a jack-type actuator, which also allows a second part, located in front of the first part and also designed to receive a portion of the wheel, to move closer relative to the first part in its second position, so that said first and second parts clamp the front wheel tire.

[0006] Among the aforementioned prior art, French patent application FR2860485 describes a self-locking wheel-locking device comprising a first part, forming a shoe, designed to receive the front wheel and to pivot from a first position for receiving the wheel to a second position for locking the wheel in said first part. In the second position, the first part cooperates with a second stationary part, disposed in front of the first part and also designed to receive a front portion of the wheel, said first and second parts clamping the front wheel tire. The first part can be moved relative to the second part to adjust the spacing between these two parts and adapt their positions relative to the diameter of the wheel.Self-locking wheel-locking devices, exhibiting similar characteristics, are also described in US patent application US2009001031, Canadian patent application CA2729670A1, international patent applications WO2011141694 and WO2016005828, and patent application ES2550531. Summary of the invention

[0007] The present invention aims to design a self-locking wheel-blocking device which allows simple adjustment to different diameters of cycle wheels, without requiring manual intervention by the users of said self-locking wheel-blocking device.

[0008] According to the invention, the self-locking wheel-locking device comprises a base, a first part, and a second part. The first part comprises a first portion and a second portion forming an obtuse angle in a longitudinal cross-section of said first part. Furthermore, the first part forms a first groove configured to house a first portion of a bicycle wheel. A first pivot joint is arranged between the first part and the base along a first axis transverse to said first part and defined in a plane of junction between the first and second parts.The first part is configured to pivot about the first axis, from a first position where the first part comes into contact with the sole or, at least, is brought close to said sole, in order to allow the wheel to be inserted into the first part, to a second position where the first part is away from the sole and, conversely, the second part is brought closer to the sole due to said pivoting, the first portion of the wheel then being housed in said first groove. The second part forms a second groove configured to house a second portion of the bicycle wheel.

[0009] According to the invention, the self-locking wheel-blocking device comprises a sliding link arranged between the second part and the sole to move said second part along a second axis, perpendicular to the first axis, when the second portion of The wheel comes into contact with the second gutter during the pivoting of the first part towards its second position. Furthermore, according to the invention, the self-locking wheel-blocking device includes an automatic locking system configured to lock the relative position of the second part and the first part when said first part reaches its second position.

[0010] In practice, the bicycle wheel, preferably the front wheel, is inserted into the first part, initially in the first position. The forward movement of the bicycle and the wheel then causes the first part to pivot, while the second part remains temporarily stationary until the wheel makes contact with said second part. The second part then translates along the second axis as the wheel continues to move forward. The first part also continues its pivoting until it reaches its second position, at which point the automatic locking system engages and prevents the second part from moving further, as well as the first part from pivoting beyond said second position. Thus, the distance between the first and second parts adjusts naturally to the diameter of the bicycle wheel, that is, without any intervention on said self-locking wheel-locking device.

[0011] According to one embodiment of the self-locking wheel-locking device of the invention, the device comprises two rods arranged respectively on the transverse sides of the first part and mounted to slide on the base in the direction of the second axis. The two rods are attached to the second part, at least one of the two rods comprising a rack. In addition, the second part of the first part comprises at least one locking member configured to engage in a notch of the rack present on at least one of the two rods when said first part reaches its second position. Preferably, according to this embodiment, each of the two rods comprises a rack, the second part of the first part comprising two locking members configured to engage respectively in the notches of the two racks when said first part reaches its second position.

[0012] Variations can be considered for mounting the second part to the base via a sliding connection along the second axis. For example, a guide rail arranged on the base along the second axis can slidably receive a lower face of the second part. Variations of the automatic locking system are also conceivable, for example, a locking member on the second part of the first part that engages with a complementary locking member arranged directly on the second part when the first part reaches the second position.

[0013] According to one embodiment of the self-locking wheel-blocking device, it comprises a first return system arranged between the base and the second part and configured to translate the second piece along the second axis towards a position closer to the first piece, when said first piece pivots towards its first position.

[0014] According to an embodiment of the self-locking wheel locking device comprising the first return system and the two rods mentioned above, said first return system comprises at least one spring arranged on at least one of the two rods, the at least one spring being mounted in compression between the second part and at least one bearing of the sliding joint. Preferably, two springs are arranged respectively on the two rods. Variations of the first return system are conceivable, for example, a spring arranged between the second part and the base to operate in tension rather than compression.

[0015] According to one embodiment of the self-locking wheel chock device of the invention, the latter comprises a second return system arranged between the base and the first part and configured to return said first part to its first position when the wheel is released. Thus, this second return system makes it possible to exert a force on the first part to force it to pivot around the first axis, from the second position to the first position, when the wheel of a parked bicycle is released from said self-locking wheel chock device, said first part then being suitably positioned, in the first position, to receive the wheel of a subsequent bicycle.

[0016] According to one embodiment of the self-locking wheel chock device of the invention, it is configured to receive a wheel with a diameter between 550 mm and 700 mm. This is not limiting; other wheel diameter ranges that can be accommodated by the self-locking wheel chock device remain conceivable.

[0017] According to one embodiment of the self-locking wheel-locking device of the invention, this device comprises a locking system configured to prevent the removal of a wheel locked between the first part and the second part when said first part is in its second position. Preferably, according to this embodiment, the locking system comprises two arms forming a jaw, arranged respectively on the transverse sides of the first part, downstream of said first part. The two arms are pivotally mounted about two axes parallel to the second axis, each of the two arms comprising a stop member configured to come into contact with the second part of the first part when it pivots into the second position.These two arms are configured to pivot from a spread position when the first part is in its first position, allowing the wheel to pass between the two arms, to a close position when the first part reaches its second position, with the two arms gripping a wheel rim to prevent the wheel from being removed. Preferably, according to this embodiment, the locking system includes a latch configured to prevent the pivoting of the first part when said first part is in its second position. Other variations. The locking system is possible, for example by providing a particular shape of the second part which would be configured to ensure the locking of the wheel held by the first part and the second part, in the second position of said second part, a lock then ensuring the locking of the first part in its second position.

[0018] According to one embodiment of the self-locking wheel-locking device of the invention, the device comprises a shield attached to the base and including at least two side walls arranged side by side on the sides of the first and second parts. These side walls are configured to prevent access to the axle of a wheel placed in the self-locking wheel-locking device in the second position of the first part. Thus, it is impossible to remove the wheel from the rest of the bicycle once the wheel is placed in the self-locking wheel-locking device. The shield will preferably have a bottom wall connecting the side walls, so as to form a rigid shell that encloses the other parts of the self-locking wheel-locking device on its sides and rear.Preferably, according to this embodiment of the self-locking wheel chock device, each of the two side walls includes a slot configured to accommodate a chain or padlock for locking a wheel onto said self-locking wheel chock device. This enhances the security of said self-locking wheel chock device.

[0019] The invention also relates to a bicycle parking installation, which includes at least one self-locking wheel-blocking device having at least the aforementioned essential characteristics. Brief description of the figures

Detailed description

[0021] In the rest of the description: - the term device refers to the self-locking wheel-blocking device according to the invention, unless otherwise indicated in the description; - the same references are used to describe the same characteristics on the different illustrated variants, unless otherwise indicated in the text; - terms such as "high", "low", "lower", "higher", "front", "back", "lateral"... which could be used, will be in consideration of a position of use of the device resting on a horizontal surface, for example a slab or the ground, the user being placed opposite the device and ready to insert a wheel of the cycle into the first part of said device.

[0022] With regard in particular to figures 1 and 2, the device 1 includes a base 2 which is intended to rest on a surface, for example a floor covered with asphalt, a concrete slab or paving stones, said base 2 being able for example to include passage holes 32 on its peripheral portion 3, for example in the four corners of the base 2 when the latter has a rectangular shape, as illustrated by these figures 1 and 2.

[0023] With particular reference to Figures 1 and 2, the device 1 comprises a first part 4 which has a first portion 5 and a second portion 6. The first part 4 has, in a longitudinal section plane, for example the median plane PI illustrated in [Fig. 1], a V-shaped form, the first portion 5 and the second portion 6 forming between them an obtuse angle α illustrated in Figures 3 and 6, this obtuse angle α being preferably between 140° and 150°, preferably equal to 145°. As shown in Figures 1 to 6, this first part 4 has, in a transverse section plane P2 ....[l], a U-shaped or V-shaped component, said first part 4 thus forming a first groove whose shape and dimensions allow it to accommodate a first portion of a bicycle wheel, preferably a front wheel of said bicycle, preferably a front wheel of a motorcycle or scooter, the device 1 however being adaptable to accommodate bicycle wheels, or even simultaneously a wheel of a motorcycle, a scooter, or a bicycle. The first part 4 is mounted by pivot joint 7 along a first axis XI opposite the base 2, as shown in Figures 1 to 6.The pivot joint 7 along the first axis XI, implemented between the first part 4 and the base 2, comprises two bearings 8 arranged respectively on the two transverse sides 4a, 4b of the first part 4 and fixed to the base 2, these two bearings 8 receiving by pivoting along the first axis XI, the two ends of an axis 9 which extends transversely at the level of a junction plane J1 between the first part 5 and the second part 6 of said first part 4. .

[0024] With particular reference to Figures 1 and 2, the device 1 comprises a second part 10 which, in a transverse section plane P3 illustrated in [Fig. 1], has a U- or V-shaped form. This second part 10 thus forms a second groove whose shape and dimensions allow it to accommodate a second portion of a bicycle wheel, while the first part 4 receives a first portion of said wheel. The U- or V-shaped form of the second part 10 may be identical to the U- or V-shaped form of the first part. Preferably, the U- or V-shaped portion of the second part is slightly larger than the U- or V-shaped portion of the first part 4 and includes two lateral extensions 11, 12 extending the V- or U-shaped portion along its sides, as shown in particular in Figures 1 and 2. These lateral extensions 11, 12 allow the second portion of the wheel housed in said second part 10 to be properly held. The second part 10 extends vertically and perpendicular to the sole 2, as shown in figures 1 to 6, but it would be possible to provide an inclination in one direction or the other with respect to the vertical.

[0025] With regard in particular to figures 1 and 2, the second part 10 is mounted in translation along a second axis X2, opposite the base 2. For this purpose, the device 1 comprises two rods 13, 14 which extend respectively along two axes X3, X4 parallel to the axis X2, these two rods 13, 14 being respectively mounted in two second bearings 15, 15', 16, 16'. The second bearing 15' receiving the first rod 13 is partially visible, but this second bearing 15' will be arranged similarly to the second bearing 16' receiving the second rod 14. The second bearings 15, 15', 16, 16' and the rods 13, 14 are slightly offset on the transverse sides 4a, 4b of the first part 4 and the second part 10, as shown in figures 1 and 2. Thus, the rods 13, 14 are mounted to slide along the axes X3, X4.

[0026] With particular reference to Figures 1 and 2, the second part 10 is mounted on these two rods 13, 14 so as to move with them. For this purpose, the base 18 of the second part 10 is fixed by means of a crossbar 19 to the ends 13a, 14a of the two rods 13, 14. In addition, the lateral extensions 11, 12 of the second part 10 are also fixed respectively to the two rods 13, 14 by means of fixing brackets 20, 20'. The fixing bracket 20', which allows the lateral extension 11 to be fixed to the rod 13, appears partially on [Fig.1], but it is preferably identical to the fixing bracket 20 which allows the lateral extension 12 to be fixed to the rod 14. Thus, a sliding of the rods 13, 14 vis-à-vis the bearings 15, 15', 16, 16' along the axes X3, X4 generates a translation of the second part 10 along the axis X2, and vice versa.

[0027] With particular reference to Figures 1 and 2, the rods 13, 14 each comprise a rack 21. Only the rack 21 on the rod 14 is visible in Figures 1 and 2, but an identical rack is also provided on the other rod 13. The second part 6 of the first part 4 comprises two locking members 22, 23 which preferably have an L-shape, these two locking members 22, 23 extending transversely respectively on the transverse sides of the first part 4, as shown in Figures 1 and 2. A leg 24 on each of these two locking members 22, 23 is dimensioned to engage in a notch of the rack 21, as shown in [Fig. 7] and will be detailed below. The right-angled shape of these two locking elements 22, 23 provides good rigidity to the branches 24.

[0028] With particular reference to Figures 3 to 6, a wheel 100 of a cycle (not shown) is presented in front of the device 1, the first part 4 being pivoted into a first position in which the first part 5 of the first part is in contact with the sole 2 or, at least, the surface on which this sole 2 is placed, as shown in [Fig. 3]. The wheel 100 is then introduced onto the first part 5 of the first piece 4 and then engaged on the second part 6 of this first piece 4. A forward movement of the wheel 100 in the direction of arrow Fl, allows a first portion 101 of said wheel 100 to rotate the first piece 4 around the first axis XI, until a second portion 102 of said wheel 100 enters the second piece 10 and comes into contact with it, which corresponds to a position illustrated in [Fig. 4]. The forward movement of the wheel in the direction of arrow Fl then allows simultaneously to continue the pivoting of the first one around the first axis XI and to translate the second piece 10 around the second axis X2, in the direction of said arrow Fl, as well as the rods 13, 14 and the rack 21 present on these rods, as shown in [Fig.6].The movements of the first part 4, the second part 10, the rods 13, 14 and their racks 21 continue with that of the wheel 100 until the first part 4 reaches a second position in which the second part 6 of said first part 4 is brought closer to the base 2, the arms 24 on the locking members 22, 23 engaging respectively in a notch 25 of rack 21 on the rods 13, 14, as shown in figures 6 and 7, position in which the wheel 100 is wedged in the device 1, a first portion 101 being wedged opposite the first part 4 and a second portion being wedged opposite the second part 10.The weight of the cycle transferred to the wheel allows the first part 4 to be maintained in the second position, the locking elements 22, 23 engaged in the racks 21 thus allowing the relative position between the first part 4 and the second part 10 to be locked, the wheel 10 thus remaining properly wedged in the device 1. .

[0029] This design, described above with reference to Figures 1 to 7, advantageously allows for the implementation of an automatic locking system that adjusts perfectly to the wheel 100, which may have different diameters, without requiring manual intervention by the operator to adapt said device 1 to the wheel diameter. As shown in [Fig. 8], the device 1 can accommodate a wheel 100a with a large diameter D1, a wheel 100b with a small diameter D2, and a wheel 100c with a diameter D3 intermediate between diameters D1 and D2. Preferably, the parameters of the device 1, in particular the obtuse angle α of the first part 4, the initial position of the second part 10, and the stroke of the second part 10, will be chosen so that said device 1 can accommodate a wheel 100 whose diameter is between a diameter D1 of 700 mm and a diameter D2 of 550 mm.

[0030] With reference to Figures 3 to 6, the device 1 includes a return spring 26 which is arranged on the rod 14, between the fixing bracket 20 and the second bearing 16, said return spring 26 being mounted in compression. This return spring 26 allows not only to keep the second part 10 pressed against the wheel 100 when the latter is engaged with the device 1, but also to automatically return the second part 10 to a position close to the first part 4 when the wheel 100 is removed from the device 1. The removal of the wheel 100 is carried out by pulling on it in the direction illustrated by the second arrow F2, opposite to the first arrow Fl, which allows the first part 4 to pivot towards its first position illustrated in [Fig.3], said pivoting allowing the arms 24 of the locking members 22, 23 to disengage from the notch 25 of the racks 21 on the rods 13, 14. This frees the rods 13, 14 and the second part 10, which can then translate in the direction of the second arrow F2 under the effect of the spring 26.Thus, the wheel 100 remains perfectly wedged in the first part 4 and in the second part 10 during its disengagement from the device 1, which allows the cycle to remain stable during its manipulation. Preferably, a second return spring is arranged in the same way between the fixing bracket and the bearing 15 on the side of the other rod 13, in order to balance the forces on the second part 10 during its return to a position close to the first part 4.

[0031] A version of device 1 without a return spring could be envisaged, but would require maintaining the cycle stable with the hands during its release and also manually bringing the second part 10 back into a position closer to the first part, before the next use of said device 1.

[0032] Other variants with a return spring are also possible, in particular by providing a return spring mounted between the sole 2 and the second part 10, which would work in tension instead of working in compression.

[0033] Figures 9 to 11 show a second embodiment of the device 1 which, in addition to the features described above for the embodiment of Figures 1 to 7, includes a locking system 27. The locking system 27 comprises two arms 28, 29 arranged respectively on the transverse sides of the first part 4, downstream of it. Upstream and downstream are defined by the direction of insertion of the wheel 100 onto the device 1, that is to say by the direction of the first arrow Fl indicated above. The two arms 28, 29 are mounted by pivot joint on two third bearings 30, 31 along two axes X5, X6 parallel to the axis X2. The two arms 28, 29 can pivot from a spread position, illustrated in [Fig. 9], to a close position, illustrated in [Fig. 11]. 10], said pivoting being initiated by the first part 4 during its pivoting towards its second position illustrated in [Fig. 10].To achieve this, end portions 28a, 29a of the two arms 28, 29 abut against two walls 6a, 6b of the second part 6 of the first piece 4, during the pivoting of said first piece 4 towards its second position. Second return springs (not illustrated) are arranged between the end portions 28a, 29a of the arms 28, 29 and the third bearings 30, 31 in order to return said arms 28, 29 to . offset position when the first piece 4 pivots towards its first position illustrated in [Fig.9]. In the extended position of the arms 28, 29, the spacing between them is greater than the width of the rim 103 of the wheel 100, thus allowing the wheel 100 to pass through and be accommodated by the second portion 102 of this wheel 100 in the second part 10 of the device 1. When the arms 28, 29 pivot towards the extended position under the action of the first part 4 pivoting towards the second position, the arms 28, 29 clamp onto the rim 103 of the wheel 100, which prevents the wheel 100, secured in the device 1 as explained previously with reference to Figures 3 to 6, from being removed. A lock (not shown) can be arranged in the axis 9 of the first part 4, so as to lock said first part in its second position, thus keeping the wheel locked onto the device 1 by means of the locking system 27.

[0034] Figure 12 shows a third embodiment of the device 1 which, in addition to the features described previously for the embodiment of Figures 1 to 7, or even for the embodiment of Figures 9 to 11, includes a shield 33. This shield 33 comprises a rigid shell 34 having two side walls 35, 36 and a bottom wall 37 which define an open perimeter 38 allowing the wheel 100 of the cycle to be housed in said rigid shell 34. This rigid shell 34 is fixed to the base 2, for example by welding, and encloses all the other elements of said device 1, namely in particular the first part 4, the second part 10, the rods 13, 14, while allowing the movement of the second part 10 and the rods 13, 14 when a wheel 100 is introduced, in the manner already explained previously. The shape of the rigid hull 34 as illustrated in [Fig.12] allows, when a wheel 100 is inserted into the first part 4 and the second part 10 and when the second position of the first part 4 is reached, the axle 104 of the wheel 100 (shown in [Fig. 8]) to be housed inside the rigid shell 34, the two side walls 35, 36 being juxtaposed to the sides of the wheel 100, which prevents any possibility of dismantling the axle of the wheel 100 in order to detach it from the rest of the cycle. In addition, openings 39, 40 are provided on the side walls 35, 36, as illustrated in [Fig. 8]. 12], these lights 39, 40 allowing the passage of a chain and / or a padlock to chain the wheel 100 to the rigid shell 34. These lights 39, 40 will therefore allow the cycle to be attached to the device 1 by means of a chain and / or a padlock.A variant of the shield 33, without these lights 39, 40 on the rigid shell 34, may be envisaged, in particular when the device 1 also includes a locking system 27 as described previously with regard to figures 9 to 11. It would be possible to consider a variant of the shield 33 with only the two rigid side walls 35, 36 fixed to the base 2, for example by welding, the two side walls 35, 36 being arranged in such a way. juxtaposed to the transverse sides 4a, 4b of the first piece 4 and to the lateral extensions 11, 12 of the second piece 10, so that these two lateral walls 35, 36 are juxtaposed to the sides of the wheel 100 placed in said device 1.

[0035] For these three embodiments of device 1 described above with reference to Figures 1 to 7, Figures 9 to 11 and [Fig. 12], a return system (not illustrated) is preferably provided between the base 2 and the first part 4 in order to automatically return it to its first position when the wheel 100 is disengaged from device 1, i.e. during the disengagement of this wheel 100 from said first part 4.This return system may consist of a torsion spring (not illustrated), also called a spiral spring, mounted inside a housing 42 (illustrated in figures 7 and 11 and also valid for the third embodiment) on one of the two bearings 8, or even a torsion spring in each of the two bearings 8, said or said torsion springs being arranged between, on the one hand, the shaft 9 attached to the first part 4 and, on the other hand, the base 2, either directly or indirectly by means of said or said bearings 8 attached to said base 2.
