Definitions

• the invention relates to the field of roller skates and relates particularly to an inline roller skate.
• a moving user may have to skate and walk alternately. This is why certain skates include a shoe, a chassis and a means for detachably retaining the shoe on the chassis. The user can thus remove the chassis of the shoe to walk.
• Such a skate is described for example in document FR 2 725 880.
• the shoe comprises a flexible sole to facilitate walking, and the chassis is extended by a platform provided for receiving the sole of the shoe.
• the user stores his two chassis for example in a bag.
• the storage of the frames is not easy because of the space.
• the invention particularly aims to facilitate the storage of the frame of a skate whose shoe and chassis are separable.
• the invention provides an in-line roller skate comprising a flexible shoe, a chassis and a means of removable retention of the shoe on the chassis, the chassis extending in longitudinal and transverse directions which are respectively substantially the same as the longitudinal and transverse directions of the shoe when the latter is retained on the chassis, the shoe also comprising a platform designed to receive at least a portion of the sole of the shoe.
• the skate is characterized in that the platform is movable in at least one direction relative to the chassis, so as to vary the transverse size of the assembly comprising the platform and the chassis.
• the width variation can also be used depending on the skating practice: speed skating requiring very high lateral stability does not require a wide platform. On the other hand, the widening of the platform gives the skate greater maneuverability.
• the platform is generally made of a material as rigid as the chassis, it is possible to optimize its positioning as a function of the zones where the greatest forces are transmitted. Thus a small platform will be placed substantially under the metatarsophalangeal joint.
• the invention can also be used in a skate whose shoe is not removable.
• the platform is inserted between the chassis and the shoe and has a space allowing the variation of its transverse dimensions.
• the platform is able to receive the sole of the shoe so that the metatarsus is fully supported on the platform through the sole.
• the first and fifth metatarsals are used to transmit driving impulses to the chassis.
• the advantage of the set is that it can both be easily stored and allow efficient driving of the skate.
• the platform is retractable relative to the chassis, guide means allowing a displacement of at least a portion of the platform between at least two positions relative to the chassis, a position for receiving the shoe in which at least one end of the platform is distant from a longitudinal plane of the chassis, a chassis storage position in which the end of the platform is brought closer to the longitudinal plane of the chassis.
• the guide means may in particular be any means for guiding in rotation or any means for guiding in translation known to a person skilled in the art.
• the longitudinal plane of the chassis is preferably a plane which is perpendicular to the transverse direction and which passes through the wheels.
• the width of the chassis or of the assembly is minimal and the volume occupied by the chassis or by the assembly is minimal.
• the skate according to the invention is characterized in that the platform is articulated relative to the chassis along an axis of articulation substantially perpendicular both to the longitudinal direction and to the transverse direction of the chassis, the platform being able to occupy at least two positions relative to the chassis, a shoe receiving position in which at least one end of the platform projects relative to the chassis in the transverse direction, a position of storage of the chassis in which the end of the platform is retracted with respect to the chassis in the transverse direction.
• This embodiment is simple. It makes it possible to manufacture a robust assembly for a reduced price.
• the invention makes it possible to vary the geometry of a part of the skate to facilitate an alternative use of skating and walking.

• the chassis 2 comprises two flanges 8, 9, connected to each other by two bridges 10, 11.
• the chassis 2 serves as a support for four wheels 12, 13, 14, 15, the latter being aligned one behind the other, and rotating relative to the chassis 2 along respective axes parallel to each other.
• a longitudinal direction of the chassis 2 is defined as being substantially parallel or contained in a plane containing the axes of the front 12 and rear wheels 15, and substantially parallel to the flanges 8, 9.
• a transverse direction of the chassis 2 is defined as being substantially perpendicular to the longitudinal direction, and substantially parallel to the axes of the wheels 12, 13, 14, 15.
• the width of the frame 2 is measured in the transverse direction, between an external face 16 of the flange 8 and an external face 17 of the flange 9.
• a front zone of the chassis 2 comprises the front axle 10 and supports the front wheels 12, 13, while a rear zone of the chassis 2 comprises the rear axle 11 and supports the rear wheels 14, 15.
• the platform 3 has an elongated plate, preferably of oblong shape, the width of which is measured between two parallel sides 18, 19, and the length of which is measured between two ends 20, 21.
• the skate comprises a removable means for retaining the boot 1 on the chassis 2. This retaining means consists partly of elements secured to the boot 1 and partly of elements secured to the chassis 2, as explained using Figures 2, 3 and 4.
• the sole 4 of the shoe 1 has three cavities 22, 23, 24, in each of which are hooking elements, represented respectively in the form of pins 25, 26, 27.
• pins are divided into two front pins 25, 26, and a rear pin 27, each of the pins having an axis oriented substantially in the transverse direction of the shoe 1.
• the platform 3 has hooking elements, represented in the form of hooks 28, 29, intended to cooperate respectively with the pins 25, 26.
• the chassis 2 is provided with a hooking element designed to cooperate with the pin 27, as explained with the aid of FIG. 4.
• the attachment element is housed in the rear axle 11 of the chassis 2. It comprises an opening handle 30, an elastic means represented in the form of a spring 31, a movable jaw 32 and a fixed jaw 33.
• the spring 31 permanently biases the movable jaw 32 in a direction of approach towards the fixed jaw 33.
• the shoe 1 is secured to the chassis 2 by proceeding as follows.
• the sole 4 is brought into contact with the chassis 2 so that the hooks 28, 29, of the platform 3 cooperate with the pins 25, 26, and so that the jaws 32, 33, cooperate with the pin 27.
• the jaw 32 is moved manually to an open position, using the handle 30, then moved elastically to a closed position against the jaw 33, by action of the spring 31.
• the hooks 28, 29, and the jaws 32, 33 are shaped so as to retain the boot 1 when the pin 27 is retained between the jaws 32, 33.
• a separation of the shoe 1 relative to the chassis 2 is done in reverse.
• a manual traction action on the handle 30 makes it possible to release the pin 27, then a movement of the shoe 1 relative to the frame 2 allows the pins 25, 26 to be released.
• the platform 3 is articulated with respect to the chassis 2 along a median articulation axis 34 substantially perpendicular to both the longitudinal direction and the transverse direction of the chassis 2. In this way, the platform 3 can rotate relative to the chassis 2 in a plane substantially parallel to the plane containing the axes of the wheels 12, 13, 14, 15.
• the pin 34 is formed by a fastening element of the rivet type 35, the latter being flattened at each end to press the platform 3 on the chassis 2.
• the rivet 35 can be replaced by other fixing means, of the removable type like a screw, ....
• An indexing means makes it possible to index the platform 3 relative to the chassis 2. This means that the platform 3 can be immobilized, in rotation, in a predetermined position relative to the chassis 2.
• the indexing means shown in Figure 5 comprises a movable stop 36 and an elastic means shown in the form of a spring 37.
• the stop 36 and the spring 37 are housed in a cavity 38 of the bridge 10, and arranged so that the stop 36 is permanently biased by the spring 37 to bear on the platform 3.
• the stop 36 includes a finger-shaped end 39 capable of entering holes in the platform 3.
• an orifice 40 in the platform 3 allows the finger 39 to immobilize the platform 3 in a position for receiving the shoe 1. This means that the ends 20, 21, of the platform 3 are projecting from the chassis 2 in the transverse direction.
• the receiving position is also visible in dotted lines in FIG. 6.
• a storage position for the chassis 2 is represented by the solid line drawing of the platform 3.
• the finger 39 takes place in an orifice 41 of the platform 3, so that the ends 20, 21 are retracted relative to the chassis 2 in the transverse direction.
• the orifice 40 remains empty.
• the platform is aligned in the longitudinal direction of the chassis.
• the transition from the receiving position to the storage position is done manually. It suffices to press with a finger of the hand on the finger 39, through the orifice 40 or through the orifice 41, to push the stop 36 and the finger 39 towards the bottom of the cavity 38 against the action of the spring 37.
• the platform 3 can be moved in rotation along the axis 34 relative to the chassis 2, until the finger 39 enters an orifice in the platform 3 to immobilize the latter.
• the hinge pin 34 is located relative to the platform 3 substantially in the middle of the platform 3 in the width direction and in the length direction, and located relative to the frame 2 in the middle in the sense of width. This allows the ends 20, 21 of the platform 3 to protrude by an equal distance on either side of the chassis 2, when the platform 3 is in the receiving position.
• the platform 3 has a width substantially equal to or less than the width of the chassis 2, and a length greater than the width of the chassis 2. This makes it possible to completely retract the platform 3 relative to the chassis 2. It advantageously follows that the size of the chassis 2 is minimal in the retracted position, which facilitates its storage in a bag or in a pocket.
• the articulation axis 34 is located, relative to the chassis 2, in the front zone of the chassis 2.
• the length of the platform 3 is substantially equal to the width of the shoe 1.
• the flat -form 3 supports the shoe 1 of the skate at the level of the metatarsus of a user.
• the latter can therefore easily transmit driving impulses to the skate wheels, especially with the first and fifth metatarsals.
• These bones are those which allow a good transmission of sensory information between the foot and the skate. he appears that the user is comfortable in all travel conditions.
• driving is easy and precise thanks to the presence of the platform 3.
• walking is easy thanks to the flexibility shoe 1
• the storage of the chassis is easy thanks to the articulation of the platform 3 relative to the chassis 2.
• skate according to the invention can be manufactured according to all techniques and with all the materials known to those skilled in the art.
• the platform 3 can be produced for example with a metal, a metal alloy, or any composite material.
• the platform 3 could have a different shape or be placed elsewhere on the chassis 2.
• a platform constituted by pivoting parts along longitudinal axes and behaving like flaps coming to be pressed against the flanges 8 and 9 of the chassis 2 .
• connecting means can be produced for example with a slide located on the chassis to cooperate with a shape complementary to the platform.
