SLIDER ASSEMBLY FOR CURLING BOOTS OR SHOES
BACKGROUND OF THE INVENTION
This invention relates to new and useful improve-ments in sliders for curling boots and shoes.
Conventionally, either a slip-on slider sole is provided, or alternatively, a flat plate of slider material is adhesively secured to the sole of the curling boot or shoe and extends over the entire surface thereof.
A slider that extends across the full surface of the sole, limits flexibility of the sole which is often de-sirable for curlers who slide on the toe areas when deliver-ing a rock and also, because it extends the full width of the sole, the curler tends to rock from side to side when delivering a rock thus making a standard delivery somewhat difficult to obtain.
SUMMARY OF THE INVENTION
The present invention overcomes these disadvanta-ges by providing perimetrical slider strips which are secu-red around the perimeter of the underside of the sole and, if desired, around the perimeter of the underside of the heel thereby supporting the sole clear of the ice surface and preventing and eliminating any rocking action which might take place with a slider which extends across the full width ~ .' -. :
of the sole.
In accordance with the invention there is provided a slider assembly for the soles of curling boots and shoes comprising in combination a perimetrical strip of slider material for securement to the exposed surface of the sole adjacent the outer perimeter of the sole thereby support-ing the sole clear of the ice surface, said slider material also being securable to and extending around the underside of the heel of the boot or shoe adjacent the perimeter there-of-Another aspect of the invention consists of a curling shoe or boot which includes an upper portion, a sole portion and a heel portion, a sliding assembly secured to the underside of said sole portion, said sliding assembly including a perimetrical strip of slider material secured to the exposed surface of the sole adjacent the outer peri-meter of the underside of the sole thereby supporting the sole clear of the ice surface, said slider material also being secured to and extending around the underside of the heel of the boot or shoe adjacent the perimeter thereof.
A further advantage of the invention, particular-ly if the invention is made in several sections as in the preferred embodiment, is that one set of slider sections can be adapted for use with a plurality of different sizes of boots and shoes thus reducing the number of sizes requir-ed to satisfy the market.
~.' 1~.38~4 A yet further advantage of the invention is to pro-vide a device of the character herewithin described which is simple in construction, economical in manufacture and otherwise well suited to the purpose for which it is designed.
~ .
1~3~94 With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompany-ing drawings forming a part hereof, which includes a descrip-tion of the preferred typical embodiment of the principles of the present invention, in which:
DESCRIPTION OF THE DRAWINGS
Figure 1 is an underside view of a curling boot or shoe showing the preferred embodiment of the invention secu-red thereto.
Figure 2 is a view similar to Figure 1, but show-ing an alternative embodiment.
Figure 3 is a fragmentary side elevation of the boot or shoe showing the rear end of the side portion un-secured from the sole.
Figure 4 is a fragmentary cross sectional view substantially along the line 4-4 of Figure 1.
Figure 5 is a fragmentary side elevation of the toe area of a boot or shoe with an alternative embodiment of the invention secured to the sole thereof.
Figure 6 is an enlarged fragmentary cross sec-tional view of one of the slider strips per se.
In the drawings like characters of reference indi-cate corresponding parts in the different figures.
DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference character 10 illustrates the underside of a sole of a curling boot or shoe which includes the sole 10 and the upper ll manufactured in the conventional manner.
In the preferred embodiment shown in Figure l, a slider assembly collectively designated 12 consists of a plurality of formed or shaped strips 12A, 12B and 12C ad-hesively secured to the underside of the sole 10 adjacent the perimetrical edge 13 thereof.
Strip 12A is an arcuately curved strip of mate-rial shown in cross section in Figure 6, formed from slid-ing material such as Teflon (trade mark) or other sliding material well known to those skilled in the art and which may include various synthetic plastics and the like.
It is provided with a planar upper surface 14 and a slightly curved under surface 15 with rounded edges 16 as shown in Figure 6 and it is secured by well known adhesives, around the toe area extending symmetrically as clearly shown in Figure 1.
Strips 12B are also shaped to follow the contours of the sides of the sole 10 and are secured one upon each side of the sole with the front ends 17 being spaced from 1~3~
the ends 18 of the toe portion 12A. The cross sectional configuration and the materials of these side strips 12B
are similar to those hereinbefore described for the strip 12A.
The gap 19 left between the strips 12A and 12B
allow toe flexibility which is often desirable for curlers who slide basically on the toe area when delivering a rock.
If desired, heel portions 12C may be secured to the underside of the sole 10 also by adhesive and these are shaped to follow the contour of the perimeter of the heel 20. Once again, gaps l9A are left between the rear ends 21 of the side strips 12B and the front ends 22 of the heel strips 12C to allow flexibility forwardly of the heel area as is desirable.
These strips support the surface of the sole clear of the ice surface at all times and prevent side to side rocking which often occurs with a slider which extends across the full width of the sole.
Alternatively, of course, the slider assembly can be made in one piece for the sole area as shown in Figure 2 and identified by reference character 23 and one piece for the heel area identified by reference character 24.
In both cases it is desirable that the rear ends 25 of the side pieces 12s or the rear ends of the one piece 1~L31~
slider portion 23 be left unsecured to the surface of the sole to provide additional flexibility in these general areas during the rock delivery action under which circum-stances, the sole of the wearer is required to flex consi-derably.
Figure 5 shows an alternative embodiment in which the thickness of the slider material is reduced as at 26, at areas requiring sole flexibility, it being understood that such an arrangement is used for the embodiment illus-trated in Figure 2.
Another advantage of the invention as compared to sliders which extend across the full width of the sole is that there is less tendency to pick up straws or other de-bris under the slider between the slider and the ice sur-face.
Furthermore, it will be appreciated that a set of slider pieces such as indicated by reference characters 12A, 12B and 12C, are readily used on the soles of boots and shoes of varying sizes merely by effective placement of the pieces, as it will be appreciated that it is not absolutely essentially that the outer edges of the slider pieces follow exactly, the outer perimetrical edges of the sole.
Since various modifications can be made in my in-vention as hereinabove described, and many apparently wide-, .
1~3~94 ly different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustra-tive only and not in a limiting sense.

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference character 10 illustrates the underside of a sole of a curling boot or shoe which includes the sole 10 and the upper ll manufactured in the conventional manner.
In the preferred embodiment shown in Figure l, a slider assembly collectively designated 12 consists of a plurality of formed or shaped strips 12A, 12B and 12C ad-hesively secured to the underside of the sole 10 adjacent the perimetrical edge 13 thereof.

It is provided with a planar upper surface 14 and a slightly curved under surface 15 with rounded edges 16 as shown in Figure 6 and it is secured by well known adhesives, around the toe area extending symmetrically as clearly shown in Figure 1.
Strips 12B are also shaped to follow the contours of the sides of the sole 10 and are secured one upon each side of the sole with the front ends 17 being spaced from 1~3~
the ends 18 of the toe portion 12A. The cross sectional configuration and the materials of these side strips 12B

If desired, heel portions 12C may be secured to the underside of the sole 10 also by adhesive and these are shaped to follow the contour of the perimeter of the heel 20. Once again, gaps l9A are left between the rear ends 21 of the side strips 12B and the front ends 22 of the heel strips 12C to allow flexibility forwardly of the heel area as is desirable.
These strips support the surface of the sole clear of the ice surface at all times and prevent side to side rocking which often occurs with a slider which extends across the full width of the sole.
Alternatively, of course, the slider assembly can be made in one piece for the sole area as shown in Figure 2 and identified by reference character 23 and one piece for the heel area identified by reference character 24.
In both cases it is desirable that the rear ends 25 of the side pieces 12s or the rear ends of the one piece 1~L31~

Figure 5 shows an alternative embodiment in which the thickness of the slider material is reduced as at 26, at areas requiring sole flexibility, it being understood that such an arrangement is used for the embodiment illus-trated in Figure 2.
Another advantage of the invention as compared to sliders which extend across the full width of the sole is that there is less tendency to pick up straws or other de-bris under the slider between the slider and the ice sur-face.
