,2,383,267` f l l y NON SKIDDING DEVICE A `Tlhurel Malinqvst, Stockholm, Sweden` Application `September 9, 1943, Serial No. l In Sweden October 2, 1942 iioiaims. -Col. :is- 66) -The present invention relates to a non-skidding device for shoes, characterized chiefly in` that 'it consists of a mounting which may be attached to the shoe beneath the shank, `preferably immediately in fronfof the heel,v as well as of aspike l fastened to thernountirig and resilientlyyieldable in the direction in .which itis pressed in, saidspike being preferably adapted tobe removably fastened to the mounting. i Thenew nonskidding `device has lthe special advantage that it does not impede the walk, not even on glassy ice or other hard foundation.`
`The invention will be more fullydescribed in the following with reference to the accompanying drawings. In the drawings Y Figures 1 and Zshow a first embodiment of l the non-skiddingdevice fastened to the shoe, in
side elevation, and as seen from below, respectively.
Figure 3 shows the same non-skidding` device on a larger scale, partly in side elevation, partly in axial section.
Figure 4 shows, likewise on a larger scale, an axial section of the mounting fastened to the shoe.
Figure 5 shows on the same scale a portion of the spikewith an addition spike crown interposed between the spike point and the spike holder.
Figureb` shows a blank from which the spike crown may be made by bending the edge flaps.
Figures 7 and 8 show a second embodiment of the non-skidding device fastened to the shoe, partly in side elevation,partly as seen from below.
Figures 9 and 10 show the mounting fastened to the shoe, partly in axial section, partly in plan View, While v Figures 11 and 12 show the spike holder with` the spikecrown, partly in axial section, partly in plan View.` y
In Figures 1-4, I designates the spike consisting of the spike point or spike crown 2 made of steel as well as the spike point vholder 3 into the plane end surface 4` of which the spike point is screwed. The spike point holder 3, which suitably has the form of a circular cylinder, projects through a corresponding hole in the bottom E of acircular box 1, which is provided with a knurled outer edge to assist in removal of the box from its mounting. At its inner end the spike pointl holder 3 is rigidly connected to a circular disc or flange 8 slidably mounted in the box` 1. A conical spring I 0 placed between said disc 8 and the cover 9 of the box tends to keep the spike I'in its wholly'extendedpositionfthe disc 8 then bearing against ,the bottom 6 of the box.
*Beneath the shankimmedi'ately in front of the heel II thereis fixed to the sole I2 a cup-shaped mounting I3 into which the `box` 'I with. its appertaining parts is adapted to be introduced and,
byrturning, xed with the help of two diametri- `callyextending pins, not shown,said"pins `passing into axially and `tangentially running slotsv 15in the mounting in thesame `manner. as in a bayonet catch. For keeping the box 'I in place in the mounting I3 there is provided a flat spring, not shown, said spring normally extending `into one of the grooves I5 withahball-shaped projection. Themounting I3 is fixedto the sole I2 with the help o'f screws passing through holes I6 in'a number of fastening lugs I'I distributed roun `the periphery of the mounting.
As appears from Figure 41,` inr which reference character I8 designates the plane of the ground, only the spike point 2 proper is generally pressed into the base, because the depth into which the spike is pressed is limited by the plane end surface 4 of the spike point holder 3. If the walker should happento step on a `foundation into which the spike point cannot penetrate,`the spike is drawn in, at the same time compressing the spring I0 and, possibly, the soft portions ofthe instep, so that the walker does not experience any discomfort. Indoors it is possible to putthe nonskidding device out of function by removingthe box 'I from the mounting I3.
As appears from Figures 5 and 6, an additional spike crown 20 in the form of a resilient intermediate steel washer may,` if desired. be placed between the spike point 2 and the spike point holder 3', said spike crown being provided with a number of downwardly bent aps `2I acting as teeth. An `additional spike of this kind works very efficiently especially insnow.
In the embodiment according to Figures 7-12 the yieldable spike consists of four flat springs 25 bent obliquely downward from a central portion, said springs being securely riveted to a sleeve-shaped spike holder 26. 'Ihe latter is intended to be pushed over a mounting 29 fixed by means of screws to the shoe beneath the shank immediately in front ofthe heel, and is adapted to be kept in place on the mounting with the help of two inwardly projecting pins 28 which pass into grooves 29 in the mounting in the same manner as in a bayonet catch. At
Obviously the invention is not limited to the vembodiments shown, but may be modied in several 'Ways without departing from the spirit of the invention.
I claim:
, 1. A non-skidding device for shoes, consisting of a mountingiadapted to be attached to the shoe beneath the shank immediately in front of the heel, and a spike removably fastened to the mounting by means of bayonet catches and resiliently yieldable in the direction in which it is pressed in.
2. A non-skidding device according to claim 1 in which the spike consists of a number of circularly arranged, obliquely downward-bent flat springs.
3. A non-skidding device according to claim 1', in which the spike consists of a number of circularly arranged, obliquely downward-bent iiat springs which are provided with rollers at their ends.
4. A non-skidding device for shoes which comprises a. cup-shaped mounting adapted to be secured to the shank of a shoe, a cylindrical box removably mounted in said cup-shaped mounting having a closed end ilush with the shank of said shoe and a lower end with an opening therein, a spike slidably mounted in the opening of said box, a compression spring mounted between said closed end and said spike and tending to force said spike downwardly into the ground, said spike having a length such that it normally projects slightly below the plane of the ground, the device being so constructed and arranged that the said spike is retracted when the wearer of the shoe steps upon a hard surface.
5. The device of claim 4 wherein said spike is provided with a flange slidable'in said cylindrical box and serving to limit the downward movement of said spike.
6. The device of claim 4 wherein said spike is in two parts, one part being the spike point, the other being a spike point holder which is slidable in said cylindrical box, said spike point being removable from said holder.
'7. The device of claim 4 wherein said cylindrical box is secured in said cup-shaped mounting by means of bayonet catches.
8. The device of claim 4v in combination with a resilient washer provided` with a plurality of downwardly bent spikes around its periphery and means for mounting said washer at the pointed' end of said spike. l
Y 9. The device of claim 4 wherein said cylindrical box is provided with an outer knurled edge to assist in removal of said box from said mounting.
10. A non-skidd-ing device for shoes which comprises a cup-shaped mounting adapted to be secured to the shank of a shoe, a spike slidably mounted in said mountingl and removable therefrom by means of bayonet catches, a compression spring tending ,to press said spike downwardly into the plane of the ground and means for limiting the downward motion of said spike.
l1. A non-'skiddingdevice for shoes which comprises a mounting adapted to be permanently secured to the underside of the instep of a shoe, a guide member removablyrsecuredin said mounting and having a lower end `with an opening therein, a spike guided for axial movement in the opening of said guide member, spring means tending to force said spike out through said opening, and, means for limiting the axial movement of said spike.
