Like parts are denoted by like reference numerals in the figures.

Detailed description

Fig. 1 schematically shows a non-slip arrangement of a footwear, seen from below and open, and Figs. 2a, 2b are seen from the side and open.

The non-slip arrangement 100 is fitted to the sole of the footwear, more particularly to the heel portion 17. In another embodiment, the non-slip arrangement 100 is mounted to the sole of the footwear other than the heel portion, e.g. In a third embodiment, the non-slip bar assembly 100 is adapted to be attached to and removed from the footwear.

The non-slip arrangement 100 comprises a lower 1 and an upper 2 layer which are at least partially overlapped. According to one idea, at least one of the layers 1,2, in one embodiment both, is an elastic material such as an elastomeric material such as rubber or a thermoplastic elastomer. It should be noted, however, that non-elastic material may also be used in both layers 1,2.

Both the upper and lower layers 1, 2 have three-dimensional shapes, such as recessed and / or protruding forms, on their surface arranged in the direction of the second layer. In the embodiment shown in Figures 1-2b, the three-dimensional shapes are wavy shapes. In other embodiments, the three-dimensional shapes may be more angular, e.g., wedge-shaped. The protruding shapes of the upper layer 2 are shaped to fit the recessed shapes of the lower layer 1 and vice versa.

The anti-slip arrangement 100 comprises at least one, but typically more, anti-slip element. In the embodiment 35 shown in Figs. 1-2b, the non-slip element is pin 5. According to one idea, pin 5 comprises

20175255 prh 26 -09-2018 with carbide tip 8 and surrounding body 15 with stems. The pin 5 is secured substantially immobile with respect to the upper layer 2 to the imaginary attachment plane 6 of the non-slip element. Said attachment plane 6 may be located on the upper layer 2 as in the embodiment shown in FIGS. 1-2b, or in any other part of the arrangement 100. the element remains in place in arrangement 100 in all its use situations.

However, it should be noted that the non-slip element may be of another type, for example, a different type of pin or something other than a pin.

The pin 5 is further arranged in a non-slip opening 7 formed in the lower layer 1 which extends through said lower layer 1 from its upper surface 4 to its lower surface 9. The non-slip opening 7 is dimensioned so that the pin 5 is movable longitudinally in the non-slip opening 7 and the non-slip opening 7 fit substantially without any play.

The non-slip arrangement 100 further comprises a transfer element 3 disposed between the upper and lower layers 1,2 for moving between and between said layers from the first position to the second position and vice versa. In the embodiment shown in Figs. 1-2b, the transfer element 3 is a circular plate fitted with an operating lever 16. The transfer element 3 can be made, for example, of metal, plastic or plastic composite. The center of the transfer element may have an aperture fitted with a non-slip element.

The transfer element 3 is formed of at least a substantially constant thickness material, the shapes of which conform to the shapes of the lower 1 and upper 2 layers when the transfer element 3 is in its first position.

The transfer element 3 is rotatable about its axis of rotation about a first rotation angle from the first position to the second position. Rotation is done by turning the operating lever 16.

The transfer element 3 comprises shapes which, in their first position 30, are arranged in said three-dimensional shapes of the lower 1 and upper 2 layers, as shown in Fig. 2a. In this case, the anti-slip element, i.e. in this embodiment, the tip 8 of the pin 5, through the non-slip opening 7, reaches the lower surface side 9 of the lower layer and the non-slip arrangement 100 acts as a non-slip. The tip protrusion can be, for example, 1 to 2 mm, for example 1.5 mm.

When the transfer element 3 is rotated by rotating the operating lever 16 from the first position to the second position, the shapes of the transfer element 3 force

20175255 prh 26 -09-2018 layers, as shown in Figure 2b. The layers are spaced apart so that the tip 8 of the non-slip element remains in the non-slip opening, i.e., the lower surface 9 of the lower layer is spaced away from the attachment plane 6 of the non-slip element at least by the protrusion of the tip. In this case, the footwear with the non-slip arrangement 100 functions like any conventional non-slip footwear. It should be noted that with the displacement element 3 in its second position, the distance between the lower 1 and upper layers 2 has increased substantially more than the material thickness of the transfer element 3, since the distance of the transfer element 3 itself has increased the distance between the transfer element 3 and the lower layer 1 has increased due to the shapes of it and the lower layer 1.

In one embodiment of the invention, the transfer element 3 moves linearly instead of circular motion.

Figure 3 is a schematic side elevational view of another anti-slip arrangement. Here, the transfer element 3 is not formed of a plate of constant thickness but comprises thinner portions 13 and thicker portions 14.

When the transfer element 3 is in its first position, the thicker portions 14 are in the recesses of the lower 1 and upper 2 layers. 2a, the tip 8 of the non-slip element extends through the non-slip opening 7 to the lower surface side 9 of the lower layer and the anti-slip arrangement 100 acts as a non-slip.

While the transfer element 3 is in its second position, the thicker portions 14 have moved away from said recesses, as a result of which the lower surface 9 of the lower layer has moved away from the anti-slip element attachment plane 6 to such an extent

Figures 4a, 4b and 4c schematically show a third solution arrangement of the solution in open cut. This comprises a lower layer 1 whose upper surface 4 has three-dimensional shapes comprising protruding shapes.

The transfer element 3 is arranged on the side of the upper surface 4 of the lower layer and is movable in this respect from the first position to the second position and vice versa. In the present embodiment, the transfer element 3 has 4 openings 18 in which the projections of the lower layer 1 fit

20175255 prh 26 -09-2018 with transfer element 3 in first position. Of course, the number of openings 18 and corresponding projections may be more than four.

In the present embodiment, at the edge of the aperture 18, there is an oblique surface 19 of the aperture which is directed in the direction of the lower surface 9 of the lower layer. As the threads 5 fill the transfer element 3 from the first position to the second position, the oblique surface of the opening pushes 19 of the holes. a projection of the lower layer 1 in the opening away from the opening 18 in the direction of the lower surface 9 of the lower layer. According to one idea, said projection also has a bevelled surface parallel to the inclined surface 19 of the aperture, which facilitates displacement of the projection away from the aperture 18. As the transfer element 3 continues its 9 moves away from the attachment plane 6 of the anti-slip element so that the tips 8 of the anti-slip elements move inside the anti-slip openings 7.

In another embodiment, the transfer element 3 has two kinds of openings 18 and furthermore, both the lower 1 and upper 2 layers have projecting shapes. When the transfer element 3 is in its first position, some of the openings are adapted to receive the lower layer projections and the other part respectively the upper layer projections. The bevelled surfaces 19 of the apertures receiving the upper layer projections are directed in the direction of the upper layer, and the bevelled surfaces 19 of the apertures receiving the lower layers are oriented in the direction of the lower layer, and further to the opposite edge of the aperture. Thus, the movement of the transfer element 3 pushes both layers 1,2 away from the transfer element 3.

The embodiment of the non-slip footwear arrangement 100 shown in Figures 4a to 4c comprises a frame element 10 which is adapted to frame the lower layer 1 and with respect to which the lower layer 1 is movable by means of a transfer element 3. The frame element 10 is made of a substantially rigid material such as metal, plastic or plastic composite. The inner member 30 of the frame element 10 has an upwardly sloping surface 11 which extends partially beneath the lower layer 1. The oblique surface 11 presses and forces the lower layer 1 upwardly, i.e. towards the level of attachment of the non-slip element 6. This allows the lower layer 1 to remain uppermost in the first position.

The non-slip elements in this embodiment are pins

5. Their vertical movement towards the lower surface 9 of the lower layer is prevented by a lip 21 disposed in the opposite direction on the outer circumference of the transfer element

20175255 prh 26 -09-2018 with structures fitted over the anti-slip arrangement 100 (not shown), and laterally on the surfaces of the anti-slip opening 7.

By rotating the displacement element 3 in its second position, it forces the lower layer 1 to move downwardly, i.e. away from the sliding element attachment plane 6 and partially past the sloping surface 11 of the frame element as shown in FIG. 5a to the right. is moved to the first position, the lower layer 1 is released from the pressure of the transfer element 3, whereby the lower layer 1 moves upwardly, partially forced by the bevelled surface 11, and the tips 8 appear from the slit openings 7.

In some cases, the features set forth in this application may be used as such, despite other features. On the other hand, the features disclosed in this application may be combined, if necessary, to form various combinations.
