Definitions

  • the present invention relates to a lift device intended to be fixed to the foot of the user and making it possible to increase the lift of the foot on a soft support such as snow, sand or water.
  • the invention relates more specifically to the raised front part called the tip. of such a lift machine.
  • lift gear of the snowshoe type
  • the spatula follows a gradually curved upward plane.
  • these spatulas were not designed specifically for walking but are inspired by spatulas ski or surf type equipment. Such a spatula is used to initiate a turn and therefore to pivot, and does not provide directional support of the racket during walking.
  • This spatula remains in the prior art, as previously described, and is provided with stiffening ribs protruding under the spatula. These stiffening ribs, even if they are positioned in the axis of the machine, are not designed to improve gliding. Indeed, they are connected to the spatula by lateral edges which form, with the spatula, non-progressive junctions, possibly reinforced with small transverse ribs external, as illustrated in the figures of said document.
  • One of the aims of the present invention is to propose a lift machine whose spatula provides directional support of the machine while maintaining good glide to facilitate the release of the machine from the soft support during the walking movement of the user.
  • Another object of the invention is to propose a machine whose spatula performs a function anti-recoil grip while improving the lift of the machine.
  • the lift has a spatula which includes a prominence fixed under the underside of the spatula, and oriented substantially along the axis longitudinal of the machine.
  • the prominence is positioned forward relative to the edges of the underside of the spatula forming a sort of bow.
  • This prominence allows the machine, when resting on the spatula, to stabilize its direction of movement along the longitudinal axis of the machine.
  • the improvement of the sliding of the spatula is obtained by sliding surfaces that connect the prominence to the edges of the spatula.
  • each sliding surface has a continuous slope.
  • FIG. 1 represents a three quarter front view of the lift machine assembly and spatula.
  • FIG. 2 schematically represents a front view of the spatula.
  • Figure 3 shows a cross-section A-A of the spatula. This cup is positioned in Figures 2 and 4.
  • Figure 4 schematically shows a side view of the spatula.
  • Figure 5 is a perspective view of the spatula according to a second embodiment.
  • Figure 6 is a section along VI-VI of Figure 5.
  • Figure 1 illustrates a general plan of the lift which consists of a frame 0 on which is fixed the user's foot by Fx fixing means such as, for example, notched strips 55 provided with tightening loops 56.
  • Fx fixing means such as, for example, notched strips 55 provided with tightening loops 56.
  • Frame 0 by its surface greater than that of the foot, makes it possible to increase the lift of the user's foot on a soft support M, such as snow, sand or water, i.e. a support which does not have sufficient lift to support, without collapsing, the user.
  • Frame 0 has a raised front part called tip 1, the underside of which is 2 is the subject of the description which follows, as well as a longitudinal axis 20.
  • FIG 2 there is the spatula 1 in front view.
  • the underside 2 of the spatula 1 includes a prominence 4 oriented substantially along the longitudinal axis 20 of the lift.
  • This prominence 4 is positioned forward relative to the lateral edges 30, 31, from the underside 2 of the spatula 1.
  • the protrusion 4 is connected to one of the lateral edges 30, 31, by a sliding surface 6, 6b.
  • the surface of slides 6, 6b has a substantially continuous slope.
  • slope surface substantially continuous a surface whose slope evolves in a substantially continuous manner. That is to say the surface does not have a very curved area, either with a small radius of curvature, or of point where a strong slope break is located.
  • the prominence 4 may have a projecting edge 4a to accentuate the effect bow, and the edges 30, 31, may have very curved zones in order to achieve a homogeneous junction with frame 0.
  • the underside 2 of the tip 1 includes only one and only prominence 4 positioned on the median axis of the frame 0 of the lift.
  • this prominence 4 extends laterally two sliding surfaces 6, 6b, which respectively join the edges 30 and 31 of the spatula 1.
  • the prominence 4 associated with the sliding surfaces 6, 6b makes it easier to exit the machine lift of snow or sand during the stride movement of the user.
  • the prominence 4 provides a directional effect on the sliding which reinforces the kinematics of the movement of the user's legs during walking. This association of means avoids straining the ankles, knees and hips the user by lateral or rotating parasitic movements. It thus preserves the said joints of possible sprains.
  • protrusions 4 projecting from the underside 2 of the spatula 1, which will be arranged substantially symmetrical with respect to the median axis of the lift machine.
  • the two prominences located outside the spatula will be connected at the edges 30, 31, by sliding surfaces in accordance with the description above.
  • the prominences will also be interconnected by sliding surfaces which have a continuous slope.
  • the scales 3 are positioned substantially symmetrical with respect to the longitudinal axis 20, and are surrounded by a sliding surface 6c, 6d, respectively at the level of the lateral edges 30 and 31.
  • the sliding surfaces 6c and 6d are here constituted by a downward extension sliding surfaces 6 and 6b.
  • FIG. 3 illustrates the cross section A-A, positioned in FIGS. 2 and 4, in a plane perpendicular to the tip 1 of the lift.
  • This figure represents a mode of embodiment in which the lower face 2 constitutes an independent part which is fixed to the spatula 1 by suitable fixing means such as screws 10.
  • the face lower could also be an integral part of the spatula.
  • This figure specifies the preferred geometry for sliding surfaces 6 and 6b. The following description does not relates to the sliding surface 6b, but could advantageously be applied to the surface gliding 6 in particular by symmetry with respect to the prominence 4.
  • the sliding surface 6b comprises two distinct zones G1 and G2 separated by a point inflection I.
  • the first zone G1 which is delimited by the prominence 4
  • the surface of slide 6b defines, in transverse direction, a convex curve, that is to say that it tends to form a protruding bump on the underside of the lift.
  • the sliding surface 6 defines a concave curve, it is at say that it tends to form a hollow.
  • This constructive arrangement makes it possible to associate the lift of the concave part on the edges 30, 31, and the sliding of the convex part around the prominence 4.
  • sliding surfaces 6, 6b which are simply convex or concave, therefore without inflection point, depending on whether one wishes to favor gliding or lift.
  • Figure 4 allows to specify, thanks to its side view, the position of the scales 3 in the direction longitudinal with respect to the sliding surface 6.
  • the prominence 4 comprises three zones separate.
  • a raised area 50 located at the front end of the spatula 1, and extending almost vertically, a slightly raised area 70 which extends the bearing capacity of the frame 0, and a transition zone 60 which has a strong curvature and which is situated between the zone raised 50 and the slightly raised area 70.
  • the gliding surface is positioned on the raised zone 50 as well as on the transition zone 60, and the scales 3, 3a, 3b, are positioned on the slightly raised area 50.
  • the zones 50, 60 slide on the snow and the strong inclination of these two zones 50, 60, transforms the horizontal thrust into vertical thrust which helps to get the machine out snow.
  • the scales 3, 3a, 3b which are positioned on the slightly raised area 50 are in contact with the snow and can, thanks to their concavity 5, provide retention towards the rear of the machine.
  • the scales 3, 3a, 3b are arranged behind the sliding surface 6, 6b.
  • the scales 3, 3a, 3b also include a sliding zone 15, located in front of the retaining concavity 5, which has a downward inclination and rearward.
  • the scales 3b which are located near the transition zone 60 are set back from the prominence 4, while the scales 3a located at the opposite are arranged projecting from the prominence 4. This respect for such constructive arrangement ensures good progressiveness between the sliding function on the front of spatula 1, and the retaining function on the back of it.
  • the scales 3, 3a, 3b could have different geometries in accordance with the state of the art existing in the retaining scales, just as they could be replaced by other means of restraint, in particular seal skins.
  • spatula can also advantageously consist of a shell in plastic material which takes up the geometry of the underside 2 such that said shell is connected to frame 0 non-removably, or directly integrated into frame 0.
  • spatula is substantially identical to that of FIGS. 1 to 4, and the same elements are therefore designated by the same references.
  • the scales 3 are found in hollow on the upper face 1.
  • the underside 2 of the spatula 1 and / or the frame 0 may be made of polypropylene or polyamide, as well as other thermo-injected plastics.
  • the element of lift thus produced can be used, and without limitation, as a racket snow, sand racket, wake board, water surf, ... etc., that is to say with respect to any soft environment, lacking sufficient lift to support the weight of a user.
