Description

DEVICE FOR QUICK FIXING OF A SHOE ON AN EVOLUTION MACHINE

  The present invention relates to a device for quickly fixing a shoe on an evolutionary vehicle. It may be, not necessarily, a shoe with a flexible upper provided with a flexible sole according to a shoe standard intended for a specific sporting practice requiring the flexion of the sole and of the shoe, such as cross-country skiing. and / or the

  Nordic skiing or even snowshoeing.

  Anyway, the shoe is of the type comprising at the front a transverse hooking axis intended to cooperate with retaining means secured to a support plate of the machine. In order to ensure good support of the shoe, in particular when it is a flexible shoe for a sporting practice involving the condemnation of the flexibility of its sole, it is known to have means of retaining the shoe on the plate. heel integral with a slide freely mounted in a rectilinear guide of said plate to allow the adjustment of these in position vis-à-vis the front of the shoe. Such a construction is for example described in French patent application No. 00.01676 in the name of the applicant. This has the advantage of being able to adjust the device between two extreme positions corresponding respectively to the smallest size and the largest size of

  shoe which it is envisaged to mount on the retainer.

  However, a drawback of this known device is that the slider is connected to the shoe at its rear part by means of a connecting member which is

  consisting of a strap that buckles on the upper of the shoe.

  The user is therefore forced to bend down to manually ensure the

buckling of the strap.

  In addition, in this type of device, the transverse hooking axis cooperates with a hook of the plate which is directed downward, which requires the user to have to tilt his shoe very strongly forward, practically in a perpendicular manner, so as to hang the curved part using the transverse axis before folding the shoe towards

the plate for its strapping.

  This maneuver can be particularly inconvenient in certain situations,

especially during heaving.

  The object of the present invention is to remedy these various drawbacks of known devices, and for this purpose relates to a device for rapid attachment of a shoe to an evolution vehicle, effected, on the one hand, by means of 'a transverse hooking axis before the shoe intended to cooperate with corresponding retaining means secured to a front zone of a support plate of the machine, and on the other hand, by means of retaining means of the heel integral with a slide freely mounted in a rectilinear guide of said plate, to allow the adjustment thereof in position vis-à-vis the front of the shoe, characterized in that the retaining means of the front and rear

2 2820334

  of the shoe on the plate are constituted by positive locking members with automatic engagement which can be actuated against the elastic return means, without manual intervention, by the sole pressure of the shoe on the front then on the rear according to substantially vertical downward movements and consequently in a substantially horizontal position of said shoe. The present invention also relates to the characteristics which will emerge during

  the description which follows, and which should be considered in isolation or according to all their

possible technical combinations.

  This description given by way of nonlimiting example will make it easier to understand how

  the invention can be realized with reference to the accompanying drawings in which: FIG. 1 is a schematic perspective view and in longitudinal section of the device

  According to a first embodiment shown in Figures 1 to 6, the locking members 12, 40 located respectively at the front and at the rear of the plate 7 are resiliently recalled by a common means 20 connected directly and freely to each said

organs 12, 40.

  According to this same example, the front automatic locking member 12 of the shoe 2 is constituted by a fixed jaw 13 secured to the front end of the plate 7 and defining at its upper part a first groove portion 14 open upwards and by a movable or tilting jaw 15, articulated by a pin 16, directly on the fixed jaw 13 or the plate 7, and defining at a lower internal part, a second groove portion 17 open downward, complementary to the first portion groove 14, to define a housing of section corresponding to that of the transverse latching axis 4 intended to be housed therein after it has pushed back by tilting, at its upper free part 15a, opposite its axis of articulation 16, the movable jaw or rocker 15 which is integral with the elastic return means 20, common with the locking member 40 of the rear of the shoe 2, the

  base forms a slide 10 freely mounted in the straight guide 11.

  According to this same example, the rear automatic locking member 40 of the shoe 2 is constituted by a rigid spoiler 23 oriented downwards and forwards, which is erected projecting from the plate 7 and secured in movement with the slide 10 , capable of sliding freely in the rectilinear guide 11 of the plate 7 in a rearward direction F3 until 2 0 engagement of the spoiler 23 on a part of the heel area 9 of the shoe 2 forming a rim 24, taking place under the action in a forward direction F4 of the elastic return member

common 20.

  The operation of this device is as follows:

  Footwear by presentation of shoe 2 in a substantially horizontal plane above

  above the quick fixing device 1 and lowering according to the arrows F1, F2 (Figure 2).

  Presentation of the axis 4 of the shoe 2 on the front locking member 12 having the effect of pivoting the rocker 15 around the axis 16 in a direction F5 and tilting of the

  According to the second embodiment, the front automatic locking member 12A of the shoe 2, particularly visible in FIGS. 7, 8 and 9 is constituted by a fixed jaw 13A secured to the front end of the plate 7A and defining at its upper part a first groove portion 14A open upwards, and by a movable or tilting jaw 15A articulated 16A at the end of the plate 7A near the fixed jaw 13A and defining an upper internal part, a second portion of groove 17A open downward, complementary to the first 14A to define a section corresponding to that of the transverse latching axis 4 intended to be housed there after it has pushed back the jaw

  mobile 15A against its own elastic return means 20A.

  Advantageously, the fixed jaw is obtained in one piece with the plate 3 during a

  same operation of molding a plastic material.

  According to an improvement on the above characteristic, the groove portion 14A of the fixed jaw 13A and the complementary groove portion 17A of the movable jaw 15 have external engagement ramps 18 and 19 defining between them a V in

  which is positioned the transverse axis 4, prior to its engagement.

  Furthermore, the rocker 15A has a nose 15a directed forwards in a direction opposite to that of the energy lug 20A relative to the articulation axis 16A, so as to

  allow its tilting around said axis during an unlocking maneuver.

  To facilitate unlocking and consequently heaving, a stop 22 is produced on the upper part of the rocker 15A, which stop is acted upon during this

  operation by the front part A of the shoe 2.

  As regards the rear automatic locking member 40A of the boot 2, this is constituted by a rigid spoiler 23A oriented downwards and forwards, which is erected projecting from the plate 7A and secured in movement of the slider lOA which is capable of sliding freely in the rectilinear guide 11 1A of the plate 7A in a rearward direction F3 until the spoiler 23A engages on a part of the heel 9 of the shoe 2 forming a rim 24A, taking place under the action in a forward direction F4 of an elastic return member which is specific to it and distinct from the elastic return member 20A of the locking member

before 12A.

  3 0 According to this same embodiment, the slide 1OA consists, on the one hand, of an internal part or strip 26 of width substantially corresponding to a lower internal groove 27A of the plate 7A forming the rectilinear guide 11, and d on the other hand, an external part or back 28 extending perpendicularly the spoiler 23A towards the front and bearing on the upper plane 29 of the plate 7A, the strip 26 and the back 28 constituting the

  slide 10A being joined together by assembly means 30.

  According to a particular characteristic of the spoiler 23A, it has on its part

  upper a slope of shoe 31 directed forwards and downwards.

  Furthermore, the spoiler 23A is made integral with the upper external part or back 28 of the slider 10A by means of a perpendicular extension 32 thereof, on

  which is fixed to said spoiler 23A by assembly means 33.

  As is particularly visible in FIG. 8, the spoiler 23A and the extension 32 of the back 28 of the slider 10A on which it is fixed form an interface comprising complementary teeth 34 allowing a height adjustment, so as to make the member of

  rear lock 8A adaptable to all shoe heights.

  According to another characteristic of the invention, the elastic return member 25 of the slide A and of the spoiler 23A which is integral therewith consists of a rubber band, perforated 1 0 over its entire length with successive adjustment holes 35 including l 'one end cooperates with a pin 36 made under the underside of the back 28 of the slider lOA and one of the others, chosen as a function of the length of the shoe 2 and the desired restoring force F4

  cooperates with a fixed pin 37 produced on the upper face 29 of the plate 7A.

  Preferably, the attachment pin 36 of the end of the rubber band 25, produced under the back 28 of the slide 10A is disposed in the same longitudinal alignment as another blind and threaded pin 38, also produced under the underside of the back 28 of the slider 10A, this being intended for fixing the strip 26 of the slider 10A, so that the two pins 36 and 37 can constitute guides of said slider 10A

  by displacement in a longitudinal lumen 39 of the plate 7A which they pass through.
