Definitions

  • the invention relates to an exercise device comprising a board-like member having a top surface for attachment of a binding thereto and a bottom surface, a runner blade mounted lengthwise to the bottom surface of said board-like member, said runner blade having a front end section, a central section, and a rear end section, said runner blade having substantially parallel sides and an ice engaging lower surface, said runner blade having edges formed by the intersection of said sides and said lower surface to form laterally opposed ice-contacting edges, said runner blade and said board-like member each being of substantially equal length.
  • the exercise device of the present invention is a novel wintertime device for gliding over smooth or rough ice and snow-patched ice.
  • wintertime recreational or exercise devices for use on ice have included ice skates, such as the speed skates described in U.S. Patents 475,926, 539,641 and 568,547, and the recreational devices described in U.S. Patents 1,013,154 and 3,879,047.
  • the recreational device described in U.S. Patent 3,879,047, issued to John MacDonald, on April 22, 1975, has an elongated body which generally defines an elliptical plinth which approximately conforms to the dimensions of the user's foot.
  • the body comprises a substantially flat upper surface which supports the foot of the user and a lower ice contacting surface which is configured for rocking the body about its longitudinal axis and about an axis perpendicular to its longitudinal axis for control of the ski.
  • This type of ski is to be used on a sloping ice surface or on a flat ice surface where the participant is towed.
  • Another conventional wintertime activity is cross-country skiing.
  • a participant of this activity depends upon his/her own stride and pole thrusts to move across the snow and on the snow conditions.
  • the skier needs sufficient snow in order to be supported on the snow and the snow needs to be of a good quality, e.g. not too rough or icy.
  • a layer of ice over snow could prove hazardous for the cross-country skier.
  • the icy conditions could cause the skier to lose control and balance as the skier attempts to ski across the surface.
  • a known device described in DE-C-122386, issued to Paul Schmahl on July 22, 1901, is an exercise device designated to be used like a skate on snow.
  • This device includes the features of the pre-characterizing portion of claim 1. Attached to the top surface is a rigid binding structure and attached to the lower surface is a gliding edge which has a width three to four times the width of a skating blade. This device was designated for gliding on snow in a similar manner that one would skate on ice.
  • snow-patched ice means patches of snow on an iced over lake. Snow-patched ice typically presents a non-uniform surface.
  • Applicant is not aware of a recreational device which may be used on uneven or rough ice, such as the ice typically found on frozen lakes in the wintertime. Therefore, a device which can be used on either smooth or rough ice or snow-patched ice offers significant advantages and commercial prospects. This invention in essence provides a new type of wintertime exercise activity.
  • An object of the present invention is to provide recreational users, exercisers or competitors with a new wintertime device for use on smooth or rough ice and snow-patched ice, which permits gliding over rough ice or snow-patched ice where it would ordinarily be impossible to ski or skate.
  • the invention described herein consists of a wintertime exercise device as specified in claim 1, which may be used on ice which is smooth or, more advantageously, on rough ice or snow-patched ice.
  • the wintertime exercise device consists primarily of an elongated board-like member and an elongated runner or blade.
  • the board-like member has a top surface and a bottom surface and is longer than 76 cm (thirty inches).
  • the runner is also longer than 76 cm (thirty inches) and is mounted to the bottom surface of the board-like member.
  • the wintertime exercise device generally denoted (10) includes a board-like member (12) and a runner (14).
  • Board-like member (12) e.g. made of ash, is preferably at least 0,91 m to 1,22 m (three to four feet) long.
  • Member (12) has a top surface (13), a bottom surface (23), a front end (22) and a rear end (20). The tips of front end (22) and rear end (20) come to a point (see Fig. 5).
  • the underside of front end (22) of board-like member (12) is curved inward (see Fig. 2) in order to facilitate the member's riding over bumps and ridges in the ice.
  • the underside of the rear end (20) (see Fig. 3) is also curved inward.
  • Top surface (13) is substantially smooth and flat (see Fig. 5). It may be equipped with a binding (16) which is similar in construction to a cross-country racing ski binding. Binding (16) functions to secure a user's foot to top surface (13) of board-like member (12).
  • Bottom surface (23) of board-like member (12) contains a groove (24) (see Figs. 2 and 3).
  • Groove (24) is, for example, 1,27 cm (one-half inch) deep and runs substantially the length of board-like member (12). As seen in Figs. 2 and 3, groove (24) enables runner (14) to be received. Runner (14) may be secured in groove (24) by any conventional means, such as glue. It extends about 1,27 cm (one-half inch) below member (12).
  • Runner (14) preferably made of stainless steel, is, for example, 0,16 cm (1/16 inch) thick , 2,54 cm (one inch) wide and extends lengthwise substantially from rear end (20) to front end (22) of board-like member (12).
  • Runner (14) is preferably rockered to a radius of about sixty meters and is sharpened flat except within 7,6 cm (three inches) of each end of runner (14). The 7,6 cm (three inches) on either end of runner (14) are dulled so that the ends do not dig into the ice when the device is first contacting or leaving the frozen surface. It facilitates the user in gliding over the rough or smooth icy terrain.
  • exercise device (10) of the present invention may optionally include an anti-backsliding structure (28).
  • Anti-backsliding structure (28) includes a curved segment (32). Curved segment (32) has a jagged edge and in the embodiment depicted, uniformly spaced teeth (30) which are used to dig into the ice when device (10) is forced to slide backwards. When device (10) is propelled forward, then anti-backsliding structure (28) merely moves along the ice causing very little friction.
  • Anti-backsliding structure (28) is pivotally secured to runner (14). It may be secured by any conventional means, such as with a screw. Anti-backsliding structure (28) is also preferably readily detachable from runner (14) in order to give a user the opportunity to remove it.
  • exercise device (10) is typically used in a manner similar to the use of cross-country racing skis on snow.
  • the user wears cross-country ski-type boots on each foot and then secures each foot within a binding (16).
  • the user also preferably utilizes two cross-country skiing-type poles (34) in order to supply some of the thrust necessary to propell across the frozen surface and to maintain balance.
  • These poles are manufactured of a conventional material, such as fiberglass with tungsten carbide tips.
  • the present wintertime exercise device is particularly suited for rough, icy surfaces.
  • Device (10) is equipped with a long blade or runner (14) which is attached lengthwise to the bottom surface (23) of board-like member (12) (see Figs 1 and 4).
  • the present invention provides recreational users, exercisers and competitors with a new type of wintertime activity.
  • Device (10) allows wintertime enthusiasts to participate in a new wintertime activity when the snow is insufficient or of a poor quality or the ice is inadequate or too rough for conventional wintertime activities.
