The blade when in use projects from the bottom surface of a snowboard to provide guide means to aid the user in controlling the direction of the snowboard during forward movement.
Description
RETRACTABLE GUIDE MEANS FOR A SNOWBOARD
FIELD OF INVENTION
This invention relates to guide means for snowboards and a method for propelling the snowboard in a desired direction.
BACKGROUND ART
Snowboards have gained popularity and acclaim over the years, rising from a recreational sport or hobby to a recognized Olympic sport. As such, innovations from materials used in snowboard construction to bindings have resulted in high performance boards and binding systems adapted for many different types of uses, such as for slalom, freestyle, etc.
One drawback of today's snowboard is that during non-downhill motion, forward movement is difficult to control. For example, moving to and from the lift, chalet or otherwise getting from one point to another along a flat surface or stretch, is a difficult and labourious process, especially without hawing the benefit of any previous substantial momentum. Typically, snowboards, generally have a flat or convex bottom surfaces, which tend to slip or slide sideways as their design is intended for manoeuvring down a ski slope rather than for gliding or moving in a controlled straight path along a flat surface. In order to get from a starting point to the lift, the rider has to either completely remove his or her feet from the binding systems and walk, or at least remove one foot or boot from a binding and push the snowboard along with the opposite foot while trying to adjust for the sideways slide or slippage of the board while maintaining his balance.

In the prior art, Pritchard US 6,220,631 discloses a skeg structure in which a
2 snowboard is provided with skegs extending complEaely through the board and which are in certain embodiments mounted at the rear of the board. The skegs are generally held in a locked position, and are stated to be useful for tracking and stability over snow surfaces. In the arrangement disclosed, the skeg is manually lowered into snow contact and maintained in the position with a thumb-screw forcing the skeg into continuous contact with the snow.
In contrast to the arrangement of the present invention, this reference does not have a guide in which the user while engaging a harness or binding mechanism, can lower and raise the guide means into and out of operative position, when it is desired to move or glide across a flat surface, as opposed to downhill usage.
SUMMARY OF THE INVENTION
The present invention also provides a combination of a binding and guide means which can be mounted to a conventional snowboard where the snowboard is provided with a recess for the guide means. In particular, the provision of a binding and guide means can thus provide existing snowboards with added features, which heretofore were not available in the post-market field whereby existing snowboards could be modified to provide improved characteristics.
The present invention addresses the above problem by providing a means to allow a rider to turn the binding in-line with the snowboard and a second means to facilitate tracking of the board. The tracking means consists of a retractable skate or blade which the rider may push down to act as a guide fin, blade keel or the like, under the snowboard when pushing or skating , for' example when travelling along a flat or going to or from a lift line. According to one aspect of the present invention, there is provided a retractable guide blade which allows a user to push or skate in a manner similar to that of a technique used for pushing a skateboard and move, or push forward without sliding sideways. By turning at least the front foot, it is less stressful on the knees and provides for a much more ergonomic or natural position while pushing the board with one foot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, the system of the present invention provides a snowboard having a binding, and means associated with the binding for raising and towering guide means. For ease of explanation, reference will be made to the guide means initially, with the binding components described as being in association therewith.
According to a preferred embodiment of the present invention, there is provided a retractable guide means for snowboards, including an actuation guide 10, an aperture 160, a skate or blade holder 20, and guide means in the form of a skate or blade 40. The blade or skate 40 as discussed herein is understood to incorporate retractable guide means, such as a skate, blade or the like which in use extends from a recessed position within the snowboard to act as a keel or rudder, to provide positive traction when the rider is pushing the board.
Similarly, the aperture 160 as discussed herein is understood to incorporate shapes or combination of shapes, which allow for the blade to extend from within the aperture through the bottom of the snowboard.
As illustrated in Figures 1 through 6, there is provided a guide means for use in conjunction with the binding. The guide means is in the form of a skate or a blade 40, which provides positive traction for the rider of the snowboard 150 when in an extended or in use position. In use, the blade 40 may act as a keel or ridge to provide positive traction. As illustrated, the blade 40 includes retaining or locking pins 13 or other suitable means adapted to moveably retain or lock the blade within the actuation guide 10 through a blade holder 20. A blade holder is part of the binding sub-plate or can be independently held in the snowboard core.
Desirably, a conventional snowboard 150 would be K>rovided with a slot or corresponding aperture 160 adapted to receive the blade 40 along a substantially longitudinal axis to the board. Most desirably, the aperture 160 is positioned beneath the binding or binding system mounting area, as this location or position of the retractable guide means optimizes control of the board by the user during skating or pushing of the board.
As illustrated in Figure 2, the member 10 includes a guide or groove 22, having a form of a generally S-shape or configuration. The retaining pins 13 of the guide blade 40 are adapted to inserted into the S-shaped guide 22. In use, the actuation guide 10 is rotated by the binding (described hereinafter) which allows the pins to travel along the guide 22 and allows the blade 40 to lower or raise, thus extending or retracting the guide blade 40 from a recessed position within the snowboard 150 or snowboard core 155. The actuation guide 10 may be used in combination with a binding plate or attachment plate of a modified snowboard binding system, or may be a separate element adapted to attach to a conventional binding systems. In the present embodiment, the actuation guide 10 is adapted to rotate between a first position and at least one second position, where as the actuation guide 10 rotates, the skate or guide blade holder 22 engages with the pins 13 which, from a retracted position within the snowboard, forces the blade 40 in a downward direction extending at least a portion of the blade 40 from underneath the snowboard.
In the above example, when the rider's foot, mounted preferably in a binding, is turned in line with the longitudinal axis of the board, the holder 22 is rotatably driven, thus forcing the member 40 to move downwardly relative to the board via a cam-like action. This in tum forces the blade 40 to extend below the lower face of the snowboard to provide a keel-tike function. When the rider rotates his foot in the opposite direction, the actuation guide 10 rotates, causing the skate holder 20 draw the blade 40 in an upward direction, thereby ensuring that when the users foot is in a first or non-actuated position, the blade portion is recessed within the core of the snowboard.
The blade 40 may be positioned either in a slot andlor recess 160 directly in the snowboard, or alternatively the blade portion could be used with an insert or holder 20, adapted to hold or guide the blade. Preferably, the blade 40 is provided with at least one angular or sloping end surface 44, which is curved to provide a smooth or curved surface for providing the keel-like function.
As previously mentioned, the present invention also provides a combination of a binding and guide means, which can be used to be mounted on any conventional type of snowboard. In such an arrangement, the snowrboard may be provided with a suitable aperture or recess to receive the guide means or alternatively, snowboards provided with pre-formed apertures may be used. In that arrangement, the binding can be mounted to the snowboard above the aperture by suitable means and the guide means inserted into the aperture and then operatively connected to the binding. Depending on the type of binding (e.g.
one which uses a rotatable plate as described hereinafter), the binding will be directly or indirectly connected to the guide means to actuate the same.
Desirably, the pins or extrusions 13 are coated with a non-stick material, a rubberized coating or may be formed from a rubberized material , i.e., silicone , urethane or other flexible, elastic material. This non-stick coating material could also be selected from the group including Teflon or nylon, combinations thereof or derivatives thereof. Alternatively, the pins could bye replaced by bushings or the like.
In an alternative embodiment, as illustrated in Figures 3 and 4, the retractable blade means 40 is adapted to be used as an insert, and placed within a recess or suitable housing within the snowboard 150 or snowboard core 155.
Figure 3 illustrates the retractable blade means as positioned within a snowboard 150 in a retracted or non-use position. As illustrated, the blade 40 is in a retracted position within the skate or guide blade holder 20, which is positioned immediately or substantially directly beneath the binding system tar actuation guide 10 of the snowboard 150. Actuation guide 10 as shown includes a binding engaging surface, which when actuated by the rider or user, engages with an upper portion 50 of the blade 40 through the apertures 70, which extends at least a portion of the blade 40 through the skate holder 20 and thus extends the blade 40 beneath the bottom surface 130 of the snowboard 150. The blade 40 includes a lower surface 90, and in the preferred embodiment is flush or co-planar with the bottom surtace 130 of the snowboard 150 when in a normal ~or non-actuated use.
Figure 4 illustrates an exploded view of the blade 40 and the skate or blade holder 20. As illustrated, there is provided for use with a snowboard 150, a generally T-shaped skate holder 20 having apertures 70, and is adapted to house therein a skate or blade 40. Blade 40 according to the present embodiment may be in the form of an elongated U, or C-shaped configuration, having a bottom 41, and opposed ends 42 and 43, wherein at least one end includes curved or a sloped surface 44. Desirably, flexible material 30 is positioned between the ends 42 and 43, and is affixed through conventional means (i.e., bonded, glued or the like) to the interior portion 110 of the skate or blade 40. The blade 40 has an upper surface 50 of opposed ends 42 and 43 which are adapted to protrude through apertures 70. Apertures 70 are adapted to permit the upper portions 50 to protrude there through to operatively engage with binding engagement surface of the actuation guide 10.
Flexible material 30 as illustrated includes an upper surface 60, which in use is adapted to be affixed to the upper portion 120 of the interior of the holder 20. The flexible material 30, such as silicone, urethane, or the like, is preferably fabricated from conventional materials able to remain flexible under cold conditions, and desirably retains a "memory" which enables the material to easily return to its original shape. Such materials could include non-stick coatings, such as Teflon or the like, and or other rubberized coatings as described above.
Figure 5 illustrates an alternative embodiment of the skate or blade holder 20, having a generally rounded or ovoid exterior configuration, and an interior which is adapted to receive the blade 40 as described herein. An upper surface 120 is shown positioned between apertures 70, which in use, is adapted to receive the upper portion 60 of the flexible material 30. As described above, the upper surface 60 of the flexible material 30 is adhered to the upper interior surface 120 of the holder 20 through any conventional means.
In a still further alternative embodiment, Figure 6 illu;9trates an elongated blade 40 located within a housing 11. Housing 11 may be affixed to the upper surface of a snowboard 150, and is adapted to receive a boot or other conventional binding systems. The blade 40 extends through a slot 160 or aperture within the core 155 of the board 150, when actuated by suitable actuation means.
Desirably, the bottom surface 90 of the guide blade 40 is flush or co-planar with the bottom surface 130 of the board 150 when in a non-actuated position.
A further embodiment is shown in Figures 7 through 13. A modified snowboard 150 as illustrated in Figure 7 includes an upper surface 132, a bottom surface 130, a continuous side 140, a forward or front portion 144, a rear or tail portion 146 and a blade or skate portion 40 (shown in an extended position). As illustrated, the front or forward facing portion 144 is preferably angled in an upward direction, while the rear portion or tail 146 is also angled in a generally upward direction. It is understood that the present invention may be adapted for use with various types of snowboards, for example, carving boards, boards designed for powder or slalom boards, etc., or the like, and that the present invention described herein is not limited to such.
Bindings 170 and 180 are positioned on the upper surface 132 of the snowboard 150 in a conventional manner, and may be mounted according to industry standards or dimensions in appropriate mounting areas suitable to the requirements of the board and its intended use.
Figure 7 illustrates a modified snowboard 150. As shown, the modified snowboard 150 is provided with a blade or skate 40, which, when actuated by rotation of the binding by the rider, extends from the bottom surface 130 of the snowboard 150 to provide guide means to aid the user in controlling the direction of the snowboard 150 when being pushed or propelled by the rider, which may also be referred to as scooting, skating or pushing. The blade or skate 40 when not in use is recessed within the core 155 of the snowboard 150, and is described in greater detail below.
In a preferred alternative embodiment, as shown in Figure 8, the modified snowboard 150 includes multi-position front and rear bindings 170 and 180 respectively, are able to pivot from a first position to at least a second position. As illustrated in this example, the skate or blade portion 40 is positioned beneath the foremost or front binding 170. Desirably, the snowbo2ird may include one blade by rotation of the binding. The actuating device 10 may be integrated with the binding 170 such that when the binding 170 is rotated between a non-use and in-use position, a portion of the blade 40 is extended or retracted. As the rider or user rotates the binding between the preset positions, the skate or blade portion extends through the insert 20 within the core 155 c~f the snowboard 150, and protrudes from the bottom surface 130 of the board 155 such that the blade 40 will act as a keel or rudder for the snowboard 150 to help stabilize the board while the user or rider is pushing or steering the board during skating.
The actuating means or device 10 may be of any conventional construction, that is adapted to extend and retract the blade 40 when desired. Preferably, the actuating means 10 includes a lever or cam wherein the rider actuates the blade 40 by lifting the lever or cam to extend the blade from within the insert 20 while rotating the binding.
Typically, snowboards have a generally minimal board thickness. Snowboard manufacturers design various boards for various purposes such as carving , freestyle etc., and the thickness of the boards will vary depending on the function of the board. Desirably, the blade 40 is mounted immediately below the bindings or mounting areas for the bindings (170 or 180). The blade 40, for exemplary purposes only, may extend from the bottom surface 30 of the snowboard 150 from approximately a .05 of a millimetre to a few centimetres, and preferably has a length from about 1 to 30 centimetres, and most pref~arably in the range of 5 to 20 centimetres. As understood, the extended length and width of the blade 40 will vary depending on the length and thickness of the board and the design or purpose of the board.
Figure 9 is an alternative embodiment wherein the snowboard 150 is provided with a pair of blades 40, each blade mounted or positioned beneath the bindings 170 and 180. Desirably, each blade 40 and actuating device 10 could be affixed and operated in the same manner as described above and in further detail below.
In a further alternative, embodiment, the blade 40 and the actuating means 10 may be in the form of an insert, adapted for use with conventional bindings, wherein an existing board may be modified to include the insert, as shown in Figures 3 and 4.
The blade 40 is shown in greater in Figures 10 and 11 in a retracted or non-use position and an in-use or extended position. In Figure 10, the blade 40 is shown in a retracted position, for example during normal snornrboarding use or activity.
The blade 40 is housed within the core 155 in a recess or slot 160, and is affixed within the slot or recess 160 through a flexible material 30. The flexible material 30 may be of any conventional material known in the an, or other suitable material able to remain flexible under cold conditions. In the present embodiment, flexible material 30 may be injected, precast or adhered into place with the blade 40.
Flexible material 30 is preferably affixed to a portion of the blade 40, and is adapted to travel between a non-actuated position within the core 155 of the snowboard 150 and an extended position wherein the flexible material 30 is parallel with the bottom surface 130 of the snowboard 150. The actuating means 10, which may be used as either a stand alone device or in combination with the multi-position bindings, provides the necessary forces to retract or extend the guide means 40. Additionally, the blade 40 may be constructed of a material adapted to provide a non-stick surface. Examples of such type of materials would be Teflon type non stick material. Teflon or non stick coating materials could also be employed to ensure a non-stick blade.
Figure 10a illustrates the blade portion 40 in an extended or in-use position.
As shown, the flexible material 30 is co-planar with the bottom surface 130 of the snowboard 150 . This co-planarity ensures that the blade 40 is fully extended to allow for greater control of the board during a pushing, steering or skating activity.
Figure 11 illustrates an alternative view of Figure 10, 'wherein the holder or insert 20 and the guide blade 40 is replaced by a single T-shaped blade 40a, within a recess 160a. Desirably, the skate or blade 40a preferably is, substantially co-planar with the bottom surtace of the snowboard. As shown, flexible material 30a, as selected from the above material, or alternatively springs or the like, is affixed to at least a portion of the t-shaped blade 40a in order to provide a compressive resilient or elastic member.
Figure 11 a illustrates the blade portion 40a in an extended or in-use position. As shown, the flexible material 30a has been compressed within the recess of the board, and at least a portion of the blade 40a has been extended beneath the bottom surface of the snowboard 150 .
Both Figures 10 and 11 can be used in conjunction vvith an insert 20 or 800 as described below.
Figure 12 illustrates a snowboard 150 with the binding portions 170 and 180 in an in-use or snowboarding position. As illustrated, the bindings 170 and 180 are in a preset position for snowboarding, ensuring that the glade 40 is in a retracted position. The preset position may be set using stops, releasable pins, quick release levers or bindings etc., to ensure that the sn~owboard binding does not release or move to a difFerent setting.
Figure 13 illustrates a snowboard 150 where the bindings are in a steering or skating position. The bindings 170 and 180 have been rotated such that the users's feet are positioned such that the guide means or bladle 40 has been extended and the rider can maintain control over the direction of the board while pushing with the opposite foot.
Binding 170, as illustrated in Figure 139 has been rol:ated, in this example, to allow the users front foot to face towards the front 144 of tile snowboard 150. As illustrated, the rotation of the front or foremost binding permits the rider to engage the blade 40 through the actuation means 10, or 20Ci, and to provide the user a more ergonomic body position in order to push or propel the board and the user forward.
Alternatively, the present invention may be used in combination with rotatable binding systems. Vllhen used in combination with roitatable bindings, where at least one of the bindings (170 or 180) is able to swivel and engage with the blade 40, such that the blade 40 is pushed or extended beneath the bottom surface of the snowboard 150.
Figure 14 illustrates an alterative embodiment of the present invention. As illustrated, there is provided a swivel plate system incorporating a blade suitable for use with a retractable blade according to one embodiment of the present invention. As shown, there is provided a multi-position rotatable binding and skate system generally indicated by reference number 50C~, which includes a swivel plate or base 510, an anchor plate 550, a plurality ~~f slots or grooves 520 (shown in phantom) including on at least one end 530 a tapered area thereof, a generally circular inner peripheral edge 534 for guiding the swivel plate 510 around anchoring plate 550.
The combination of the binding shown in Figure 14, and the guide means previously described, can be provided as a "set" which may be manufactured and sold for application to any conventional sr,owboard, in which the snowboard is either provided with a recess for receiving the guide means, or alternatively, the snowboard is modified to include such a recess or aperture. Thus, the binding shown in Figure 14 may be subsequently mounted to the upper surface of a snowboard over the area in which the recess is local:ed, and in turn, the guide means mounted in the recess by suitable securing mseans.
Anchor plate 550, as illustrated, is a generally circul<~r, and has a "T"

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, the system of the present invention provides a snowboard having a binding, and means associated with the binding for raising and towering guide means. For ease of explanation, reference will be made to the guide means initially, with the binding components described as being in association therewith.
According to a preferred embodiment of the present invention, there is provided a retractable guide means for snowboards, including an actuation guide 10, an aperture 160, a skate or blade holder 20, and guide means in the form of a skate or blade 40. The blade or skate 40 as discussed herein is understood to incorporate retractable guide means, such as a skate, blade or the like which in use extends from a recessed position within the snowboard to act as a keel or rudder, to provide positive traction when the rider is pushing the board.
Similarly, the aperture 160 as discussed herein is understood to incorporate shapes or combination of shapes, which allow for the blade to extend from within the aperture through the bottom of the snowboard.
As illustrated in Figures 1 through 6, there is provided a guide means for use in conjunction with the binding. The guide means is in the form of a skate or a blade 40, which provides positive traction for the rider of the snowboard 150 when in an extended or in use position. In use, the blade 40 may act as a keel or ridge to provide positive traction. As illustrated, the blade 40 includes retaining or locking pins 13 or other suitable means adapted to moveably retain or lock the blade within the actuation guide 10 through a blade holder 20. A blade holder is part of the binding sub-plate or can be independently held in the snowboard core.
Desirably, a conventional snowboard 150 would be K>rovided with a slot or corresponding aperture 160 adapted to receive the blade 40 along a substantially longitudinal axis to the board. Most desirably, the aperture 160 is positioned beneath the binding or binding system mounting area, as this location or position of the retractable guide means optimizes control of the board by the user during skating or pushing of the board.
As illustrated in Figure 2, the member 10 includes a guide or groove 22, having a form of a generally S-shape or configuration. The retaining pins 13 of the guide blade 40 are adapted to inserted into the S-shaped guide 22. In use, the actuation guide 10 is rotated by the binding (described hereinafter) which allows the pins to travel along the guide 22 and allows the blade 40 to lower or raise, thus extending or retracting the guide blade 40 from a recessed position within the snowboard 150 or snowboard core 155. The actuation guide 10 may be used in combination with a binding plate or attachment plate of a modified snowboard binding system, or may be a separate element adapted to attach to a conventional binding systems. In the present embodiment, the actuation guide 10 is adapted to rotate between a first position and at least one second position, where as the actuation guide 10 rotates, the skate or guide blade holder 22 engages with the pins 13 which, from a retracted position within the snowboard, forces the blade 40 in a downward direction extending at least a portion of the blade 40 from underneath the snowboard.
In the above example, when the rider's foot, mounted preferably in a binding, is turned in line with the longitudinal axis of the board, the holder 22 is rotatably driven, thus forcing the member 40 to move downwardly relative to the board via a cam-like action. This in tum forces the blade 40 to extend below the lower face of the snowboard to provide a keel-tike function. When the rider rotates his foot in the opposite direction, the actuation guide 10 rotates, causing the skate holder 20 draw the blade 40 in an upward direction, thereby ensuring that when the users foot is in a first or non-actuated position, the blade portion is recessed within the core of the snowboard.
The blade 40 may be positioned either in a slot andlor recess 160 directly in the snowboard, or alternatively the blade portion could be used with an insert or holder 20, adapted to hold or guide the blade. Preferably, the blade 40 is provided with at least one angular or sloping end surface 44, which is curved to provide a smooth or curved surface for providing the keel-like function.
As previously mentioned, the present invention also provides a combination of a binding and guide means, which can be used to be mounted on any conventional type of snowboard. In such an arrangement, the snowrboard may be provided with a suitable aperture or recess to receive the guide means or alternatively, snowboards provided with pre-formed apertures may be used. In that arrangement, the binding can be mounted to the snowboard above the aperture by suitable means and the guide means inserted into the aperture and then operatively connected to the binding. Depending on the type of binding (e.g.
one which uses a rotatable plate as described hereinafter), the binding will be directly or indirectly connected to the guide means to actuate the same.
Desirably, the pins or extrusions 13 are coated with a non-stick material, a rubberized coating or may be formed from a rubberized material , i.e., silicone , urethane or other flexible, elastic material. This non-stick coating material could also be selected from the group including Teflon or nylon, combinations thereof or derivatives thereof. Alternatively, the pins could bye replaced by bushings or the like.
In an alternative embodiment, as illustrated in Figures 3 and 4, the retractable blade means 40 is adapted to be used as an insert, and placed within a recess or suitable housing within the snowboard 150 or snowboard core 155.
Figure 3 illustrates the retractable blade means as positioned within a snowboard 150 in a retracted or non-use position. As illustrated, the blade 40 is in a retracted position within the skate or guide blade holder 20, which is positioned immediately or substantially directly beneath the binding system tar actuation guide 10 of the snowboard 150. Actuation guide 10 as shown includes a binding engaging surface, which when actuated by the rider or user, engages with an upper portion 50 of the blade 40 through the apertures 70, which extends at least a portion of the blade 40 through the skate holder 20 and thus extends the blade 40 beneath the bottom surface 130 of the snowboard 150. The blade 40 includes a lower surface 90, and in the preferred embodiment is flush or co-planar with the bottom surtace 130 of the snowboard 150 when in a normal ~or non-actuated use.
Figure 4 illustrates an exploded view of the blade 40 and the skate or blade holder 20. As illustrated, there is provided for use with a snowboard 150, a generally T-shaped skate holder 20 having apertures 70, and is adapted to house therein a skate or blade 40. Blade 40 according to the present embodiment may be in the form of an elongated U, or C-shaped configuration, having a bottom 41, and opposed ends 42 and 43, wherein at least one end includes curved or a sloped surface 44. Desirably, flexible material 30 is positioned between the ends 42 and 43, and is affixed through conventional means (i.e., bonded, glued or the like) to the interior portion 110 of the skate or blade 40. The blade 40 has an upper surface 50 of opposed ends 42 and 43 which are adapted to protrude through apertures 70. Apertures 70 are adapted to permit the upper portions 50 to protrude there through to operatively engage with binding engagement surface of the actuation guide 10.
Flexible material 30 as illustrated includes an upper surface 60, which in use is adapted to be affixed to the upper portion 120 of the interior of the holder 20. The flexible material 30, such as silicone, urethane, or the like, is preferably fabricated from conventional materials able to remain flexible under cold conditions, and desirably retains a "memory" which enables the material to easily return to its original shape. Such materials could include non-stick coatings, such as Teflon or the like, and or other rubberized coatings as described above.
Figure 5 illustrates an alternative embodiment of the skate or blade holder 20, having a generally rounded or ovoid exterior configuration, and an interior which is adapted to receive the blade 40 as described herein. An upper surface 120 is shown positioned between apertures 70, which in use, is adapted to receive the upper portion 60 of the flexible material 30. As described above, the upper surface 60 of the flexible material 30 is adhered to the upper interior surface 120 of the holder 20 through any conventional means.
In a still further alternative embodiment, Figure 6 illu;9trates an elongated blade 40 located within a housing 11. Housing 11 may be affixed to the upper surface of a snowboard 150, and is adapted to receive a boot or other conventional binding systems. The blade 40 extends through a slot 160 or aperture within the core 155 of the board 150, when actuated by suitable actuation means.
Desirably, the bottom surface 90 of the guide blade 40 is flush or co-planar with the bottom surface 130 of the board 150 when in a non-actuated position.
A further embodiment is shown in Figures 7 through 13. A modified snowboard 150 as illustrated in Figure 7 includes an upper surface 132, a bottom surface 130, a continuous side 140, a forward or front portion 144, a rear or tail portion 146 and a blade or skate portion 40 (shown in an extended position). As illustrated, the front or forward facing portion 144 is preferably angled in an upward direction, while the rear portion or tail 146 is also angled in a generally upward direction. It is understood that the present invention may be adapted for use with various types of snowboards, for example, carving boards, boards designed for powder or slalom boards, etc., or the like, and that the present invention described herein is not limited to such.
Bindings 170 and 180 are positioned on the upper surface 132 of the snowboard 150 in a conventional manner, and may be mounted according to industry standards or dimensions in appropriate mounting areas suitable to the requirements of the board and its intended use.
Figure 7 illustrates a modified snowboard 150. As shown, the modified snowboard 150 is provided with a blade or skate 40, which, when actuated by rotation of the binding by the rider, extends from the bottom surface 130 of the snowboard 150 to provide guide means to aid the user in controlling the direction of the snowboard 150 when being pushed or propelled by the rider, which may also be referred to as scooting, skating or pushing. The blade or skate 40 when not in use is recessed within the core 155 of the snowboard 150, and is described in greater detail below.
In a preferred alternative embodiment, as shown in Figure 8, the modified snowboard 150 includes multi-position front and rear bindings 170 and 180 respectively, are able to pivot from a first position to at least a second position. As illustrated in this example, the skate or blade portion 40 is positioned beneath the foremost or front binding 170. Desirably, the snowbo2ird may include one blade by rotation of the binding. The actuating device 10 may be integrated with the binding 170 such that when the binding 170 is rotated between a non-use and in-use position, a portion of the blade 40 is extended or retracted. As the rider or user rotates the binding between the preset positions, the skate or blade portion extends through the insert 20 within the core 155 c~f the snowboard 150, and protrudes from the bottom surface 130 of the board 155 such that the blade 40 will act as a keel or rudder for the snowboard 150 to help stabilize the board while the user or rider is pushing or steering the board during skating.
The actuating means or device 10 may be of any conventional construction, that is adapted to extend and retract the blade 40 when desired. Preferably, the actuating means 10 includes a lever or cam wherein the rider actuates the blade 40 by lifting the lever or cam to extend the blade from within the insert 20 while rotating the binding.
Typically, snowboards have a generally minimal board thickness. Snowboard manufacturers design various boards for various purposes such as carving , freestyle etc., and the thickness of the boards will vary depending on the function of the board. Desirably, the blade 40 is mounted immediately below the bindings or mounting areas for the bindings (170 or 180). The blade 40, for exemplary purposes only, may extend from the bottom surface 30 of the snowboard 150 from approximately a .05 of a millimetre to a few centimetres, and preferably has a length from about 1 to 30 centimetres, and most pref~arably in the range of 5 to 20 centimetres. As understood, the extended length and width of the blade 40 will vary depending on the length and thickness of the board and the design or purpose of the board.
Figure 9 is an alternative embodiment wherein the snowboard 150 is provided with a pair of blades 40, each blade mounted or positioned beneath the bindings 170 and 180. Desirably, each blade 40 and actuating device 10 could be affixed and operated in the same manner as described above and in further detail below.
In a further alternative, embodiment, the blade 40 and the actuating means 10 may be in the form of an insert, adapted for use with conventional bindings, wherein an existing board may be modified to include the insert, as shown in Figures 3 and 4.
The blade 40 is shown in greater in Figures 10 and 11 in a retracted or non-use position and an in-use or extended position. In Figure 10, the blade 40 is shown in a retracted position, for example during normal snornrboarding use or activity.
The blade 40 is housed within the core 155 in a recess or slot 160, and is affixed within the slot or recess 160 through a flexible material 30. The flexible material 30 may be of any conventional material known in the an, or other suitable material able to remain flexible under cold conditions. In the present embodiment, flexible material 30 may be injected, precast or adhered into place with the blade 40.
Flexible material 30 is preferably affixed to a portion of the blade 40, and is adapted to travel between a non-actuated position within the core 155 of the snowboard 150 and an extended position wherein the flexible material 30 is parallel with the bottom surface 130 of the snowboard 150. The actuating means 10, which may be used as either a stand alone device or in combination with the multi-position bindings, provides the necessary forces to retract or extend the guide means 40. Additionally, the blade 40 may be constructed of a material adapted to provide a non-stick surface. Examples of such type of materials would be Teflon type non stick material. Teflon or non stick coating materials could also be employed to ensure a non-stick blade.
Figure 10a illustrates the blade portion 40 in an extended or in-use position.
As shown, the flexible material 30 is co-planar with the bottom surface 130 of the snowboard 150 . This co-planarity ensures that the blade 40 is fully extended to allow for greater control of the board during a pushing, steering or skating activity.
Figure 11 illustrates an alternative view of Figure 10, 'wherein the holder or insert 20 and the guide blade 40 is replaced by a single T-shaped blade 40a, within a recess 160a. Desirably, the skate or blade 40a preferably is, substantially co-planar with the bottom surtace of the snowboard. As shown, flexible material 30a, as selected from the above material, or alternatively springs or the like, is affixed to at least a portion of the t-shaped blade 40a in order to provide a compressive resilient or elastic member.
Figure 11 a illustrates the blade portion 40a in an extended or in-use position. As shown, the flexible material 30a has been compressed within the recess of the board, and at least a portion of the blade 40a has been extended beneath the bottom surface of the snowboard 150 .
Both Figures 10 and 11 can be used in conjunction vvith an insert 20 or 800 as described below.
Figure 12 illustrates a snowboard 150 with the binding portions 170 and 180 in an in-use or snowboarding position. As illustrated, the bindings 170 and 180 are in a preset position for snowboarding, ensuring that the glade 40 is in a retracted position. The preset position may be set using stops, releasable pins, quick release levers or bindings etc., to ensure that the sn~owboard binding does not release or move to a difFerent setting.
Figure 13 illustrates a snowboard 150 where the bindings are in a steering or skating position. The bindings 170 and 180 have been rotated such that the users's feet are positioned such that the guide means or bladle 40 has been extended and the rider can maintain control over the direction of the board while pushing with the opposite foot.
Binding 170, as illustrated in Figure 139 has been rol:ated, in this example, to allow the users front foot to face towards the front 144 of tile snowboard 150. As illustrated, the rotation of the front or foremost binding permits the rider to engage the blade 40 through the actuation means 10, or 20Ci, and to provide the user a more ergonomic body position in order to push or propel the board and the user forward.
Alternatively, the present invention may be used in combination with rotatable binding systems.

Figure 18 illustrates an alternative embodiment of a retractable guide means including an insert 800. Snowboards are often manuifactured from a variety or materials, and as such various types of snowboards may be formed from multiple layers of different material. Such snowboards, when an aperture or slot is formed therein, may require additional support. Insert 800 a:. illustrated is provided with a movable blade 840, an upper portion 810 and a lower corresponding portion 820.
Mounting screws 815 are provided to secure the upper and lower portion to each other. As shown, the two piece insert 800 is adapted to be affixed to an upper and a lower surface (832 and 830 respectively of a snowboard. Desirably, the lower or bottom portion 820 includes tapered edges 822, which provide additional support to the board near the slot, and also serve to protect the base or bottom sliding surface.
In another alternative embodiment, the retractable blade may be formed as an insert, having one or more sections, i.e. an upper and a lower section.
Desirably, sections are adapted to be fitted onto a pre-existing s~nowboard, or may be incorporated into the snowboard during its manufacture.
