Definitions

• the present invention relates to a sports apparatus fixing itself on the sole of a walking shoe, this apparatus being of the inline roller skate or possibly ice skate type.
• the traditional skates are in molded shell integrating both the shoe and the skate part itself. This arrangement has the disadvantage of space and the obligation to completely change the pad in the event of a change in the size of the user's foot.
• Sports devices have already been proposed which are capable of being fixed, in a removable manner, under the sole of a shoe. More particularly in document FR 2 725 880, it is a question of fixing such a device under the sole of a walking shoe, a sole which must not be altered by the fixing means, in particular as regards its walking behavior.
• the fastening system makes it possible to compensate for the difference in thickness of the sole due to the natural wear thereof during use.
• the sole comprises forwards and backwards orifices giving access to reinforced attachment zones.
• the device is fitted with hooking elements protruding from the plate which serves as a support for the sole, said hooking elements being able to engage in the orifices, when the device is mounted under the sole.
• the device comprises a movable part, carrying the hooking elements, and a manual clamping system, integral with the plate, which controls the vertical downward movement of the movable part.
• the user When the device is placed on the shoe, the user makes the hooking elements penetrate the holes of the sole so that the underside of the sole is in contact with the plate of the device, then it moves relatively one relative to the other, and horizontally the shoe and the plate so that the fastening elements are placed in the reinforced fastening zones; finally it activates the manual clamping system which moves the part mobile carrying the hooking elements down, locking the shoe in position on the plate.
• the manual clamping system consists of a clamping wheel, or even a quick-release lever of the type used on bicycle wheels, which is located under the device. Such an arrangement is hardly practical to implement by the user. In addition, it may happen that during mounting the fastening element is not precisely positioned in the reinforced fastening zone due to insufficient relative horizontal movement between the shoe and the plate.
• the aim that the applicants have set themselves is to alleviate the aforementioned drawbacks by proposing a sports apparatus which is fixed under the sole of a walking shoe which has the advantages of that described in the document FR 2 725

• This device comprises an actuation system which is able to move at least one movable attachment element for fixing the device to the sole; typically the attachment element (s), under the effect of the actuation system, has or have a displacement with two components, namely a horizontal component for placing the element above the area reinforced attachment and a vertical component for locking in position.
• the actuation system comprises, for a given attachment element, means for horizontal displacement of the movable attachment element and a stop disposed near said guide, so that, when implementing the horizontal displacement means, the guide comes to bear on the stop which forces the attachment element to follow the oblique direction of the guide.
• the movable attachment element is pushed down due to the presence of the oblique guide.
• This element therefore has an oblique displacement which includes a horizontal component and a vertical component.
• the hooking element and the guide are integral with a sliding part, arranged horizontally under the plate, which is subject to the horizontal displacement means; moreover a compression spring applies said sliding part and / or the guide against the stop.
• the horizontal displacement means comprise a lever which is provided with a handle and which is pivotable about an axis perpendicular to the plate between two angular positions, namely a first mounting position where the handle extends well outside the plate and is easily manipulated by the user and a second locking position where the handle is retracted under the plate while being accessible.
• a first mounting position where the handle extends well outside the plate and is easily manipulated by the user
• a second locking position where the handle is retracted under the plate while being accessible.
• the two hooking elements are movable and consist of bent pieces, forming a hook, with horizontal components of antagonistic displacement.
• the lever is connected to a cam with an oval outline comprising in its middle the pivot axis perpendicular to the plate located between the two hooking elements; in addition, each sliding part consists of a plate, one transverse edge of which bears on the cam, on either side of the latter, and the other edge of which is terminated by the oblique guide downwards and by the hooking element upwards.
• the compression spring may consist of a curved leaf spring, fixed along the pivot axis and the end portions of which are applied to the two sliding plates near the oblique guides.
• the actuation system remains manual, even if it is particularly simplified compared to the manual clamping system provided for in document FR 2 725 880.
• the actuation system comprises, for a given movable attachment element, a stirrup which supports a wheel, which stirrup is articulated under the plate along a first horizontal axis and has a bearing surface intended to come to apply, during skating, on the underside of the plate; moreover the movable attachment element is articulated on said stirrup along a second horizontal axis; finally, the device comprises a fixed stop under the plate and a spring pushing the attachment element in the direction of the reinforced attachment zone. All of these elements are arranged so that the bracket can take two positions, namely: a.
• a first mounting position in which the bearing surface of the stirrup is angularly offset from the underside of the plate and in which the hooking element, pushed back by the stop, is capable of penetrating into the orifice of the sole , b. a second fixing position in which, the stirrup having pivoted about its axis, the bearing surface is applied against the underside of the plate and in which the hooking element, pushed back by the spring and released from the stop , is applied against the reinforced attachment area of the sole.
• the actuation system does not consist not a joystick manipulated by the user but consists of two stirrups and their accessories which are applied to the ground by the user between the two aforementioned angular positions.
• FIG. 1 is a diagrammatic side view of the device attached to the shoe, with cutaway views in section of the locations corresponding to the fastening system.
• Figures 2 and 3 are partial bottom views of the stage of the apparatus of Figure 1 with the actuator having a first position (Fig. 2) and a second position (Fig. 3).

• the system for fixing the sports apparatus, of the skate type in particular on wheels, on the sole of a walking shoe comprises, compared to the document FR 2 725 880, an actuation system integrated, which, passing from one position to another, drives the movable fastening element (s) in a two-component movement, namely a horizontal component positioning the fastening element at the reinforced attachment zone provided in the sole and a vertical component which blocks the boot in position on the device by crushing the sole between the fastening element and the plate supporting the sole.
