Abstract
A sled includes a hull having walls defining an inboard hole. A lip extending outward from the hall forms an outboard hole opposed to the inboard hold. A support member extends through the inboard hold and the outboard hole, as well as through the hole of a strap, thereby securing the strap to the hull.
Description
- The invention relates generally to sleds, and in particular, to the attachment of straps to a sled.
- When riding a sled down a hill, a rider is often required to make rapid turns. These rapid turns result in g-forces that tend to throw the rider off the sled.
- To avoid separating the sled from its rider, it is useful to provide a strap to secure the rider to the sled. Such a strap is typically anchored to the body of the sled by strap anchors. When in use, the strap absorbs the g-forces that would otherwise throw the rider off the sled and transmits those forces to the body of the sled at the strap anchors.
- In a known strap anchor, a bolt passes through a grommet at the end of the strap. The bolt then passes through a hole in the body of the sled. A nut then engages the bolt so that the body of the sled is held between the nut and the strap.
- In use, the strap tends to rotate about the axis defined by the bolt. This rotation causes small amounts of torque to be transmitted to the bold. In many cases, the cumulative effect of these incremental torques is to work the nut loose. Unless it is periodically tightened, the nut can fall off the bolt and into the snow.
- Among the forces transmitted by the strap to the anchor are those that act in a direction orthogonal to the bolt. These forces, referred to herein as “shear forces,” cause the bolt to pivot about a fulcrum defined by the contact area between the bolt and the sled body. The cumulative effect of such pivoting can likewise result in failure of the strap anchor.
- A sled incorporating the invention eliminates the fulcrum about which the bolt can pivot and thereby provides a more secure way to attach a strap to a hull of the sled. Such a sled includes a hull having an inboard hole and a lip that extends outwardly from the hull. The lip has an outboard hole opposed to the inboard hole. A support member extends through a strap hole in a strap, through the inboard hole, and through the outboard hole.
- In one embodiment, two fins extend outward from the hull. These fins are disposed on either side of the inboard hole.
- In another aspect, the sled includes a hull having walls defining an inboard hole and an outwardly extending lip having walls defining an outboard hole, the outboard hole being opposed to the inboard hole. A support member extends through the inboard hole, and the outboard hole.
- In yet another aspect, the sled includes a strap-engaging member for receiving a shear force from a strap engaged thereto and a hull having an extended support region for receiving the strap-engaging member. The extended support region is configured to suppress pivoting of the strap-engaging member in response to the shear force.
- In one embodiment, the extended support region can include a wall forming an inboard aperture for receiving a proximal portion of the strap-engaging member and a wall forming an outboard aperture for receiving a distal portion of the strap-engaging member.
- Other embodiments include those in which an anti-rotation element is disposed to suppress rotation of the strap-engaging member when the strap-engaging member is engaged by the extended support region. The anti-rotation element can include, for example, restraining fins extending from the hull. The restraining fins are disposed to be in mechanical communication with the strap-engaging member when the strap-engaging member is engaged by the extended support region.

- As shown in
FIGS. 1-3 , the sled includes a one-piece elongated moldedhull 10, preferably of vacuum-molded thermoplastic. Thehull 10 has a bow or front-end, which is on the right as viewed inFIGS. 1 and 2 , and a stern, or rear-end, which is on the left as viewed inFIGS. 1 and 2 . - The
hull 10 presents a generally crescent-shaped profile, best seen inFIG. 2 . An upper outwardly rolled molded edge of thehull 10 forms continuous railings orgunwales 12 surrounding thehull 10. Thegunwales 12 are raised at the bow to afford handholds and to protect against the intrusion of snow. The bottom of thehull 10 while generally curved in profile as shown inFIG. 2 , includes certain features that enhance the sled's performance in deep snow. - In
FIG. 3 , a cross-section of thehull 10 reveals a pair of generally flatparallel runners parallel ribs hull 10 as it moves through the snow. Theribs hull 10 in a straight path and enhance tracking in packed snow. - In
FIG. 3 , a pair of steps formed on the sides of thehull 10 define a pair of generallyflat steering runners 44A-B integral with thehull 10. Thesteering runners 44A-B define a downwardly extending arc, best seen inFIGS. 2 and 19 , that is positioned high enough on thehull 10 so that when thehull 10 is level, the lowest points of bothsteering runners 44A-B are above the level of the snow. However, when the rider banks thehull 10 beyond a critical angle, asharp edge 46 of onesteering runner 44B contacts the snow. A downward component of the combined weight of the rider and sled is thus concentrated on the relatively small surface area of theedge 46. The extent of this downward component, and hence the pressure on theedge 46, depends on the extent to which the rider banks thehull 10, as well as on the slope of the prevailing terrain. - When the
edge 46 contacts the snow, the force acting on theedge 46 generates drag. Since only one of the twosteering runners 44A-B is in contact with the snow at any time, this drag tends to turn thehull 10. In this way, the steeringrunners 44A-B assist the rider in executing sharp turns. - The steering
runners 44A-B are of particular use in icy or crusty conditions. Under these conditions, the pressure exerted by theedge 46 of asteering runner 44B enables it to bite into hard, icy surfaces. To further enhance this ability, a sharpened steel edge can be fastened onto thesteering runner 44A-B. - Between the two
runners central channel 30 extends longitudinally from the bow to the stern of thehull 10, with progressively increasing depth as shown inFIGS. 2 and 3 . Theinside ribs channel 30 and are slightly outwardly flared with gradually increasing spacing at both ends of thehull 10. Inside thehull 10, the moldedchannel 30 forms a large longitudinal central rib or keel-like hump 32 running down the center of thehull 10. Because of the increasing depth of thesnow channel 30 toward the rear of thehull 10, thehump 32 becomes more pronounced toward the rear as shown in phantom inFIG. 2 . - An outwardly molded stern portion of the
hull 10 extends into a rear-facinglip 48, hereafter referred to as a “snow brake,” that rolls downward, as shown inFIGS. 4 and 5 . The snow-brake 48, which wraps around the stem portion of thehull 10, includes arear portion 50 and twoside portions 52A-B. The greatest extension of the snow-brake 48, both rearward and downward, is at itsrear portion 50. The extent to which the snow-brake 48 projects outward and downward progressively decreases along the twoside portions 52A-B until the snow-brake 48 merges smoothly with the gunwale 12. - To use the snow-
brake 48, a rider leans back, as shown inFIG. 6 . This causes the hull's bow to rise and its stem to sink. As the stem sinks, therear portion 50 of the snow-brake 48 comes into contact with the snow and creates drag. The extent of this drag depends on the extent to which the stem sinks. This, in turn, is controlled by the extent to which the rider leans back. - By leaning backward and sideways at the same time, the rider can cause one side of the
hull 10 to sink and the other to rise. As one side sinks, the side portion of the snow-brake 48 comes into contact with the snow and also creates drag. This drag, which only acts on one side of thehull 10, causes thehull 10 to turn swiftly in that direction. The snow-brake 48 can thus be used as a type of rudder as well as a brake. - Optional
gripping aids 54 can extend downward from the edges of the snow-brake to provide additional drag in icy conditions. These gripping aids can include teeth, as shown inFIGS. 17-19 , studs, or claws, as shown inFIG. 4 . The gripping aids 54 can be integral with the snow-brake 48 or formed on a metal plate which is then attached or fastened to the rim of the snow-brake 48. - A side-mounted snow-
brake 49 can also be mounted on the gunwale 12 at the side of thehull 10 as shown inFIG. 19 . Such a snow-brake 49 is formed by outwardly rolling the gunwale 12 so that it projects outward and downward part-way toward the snow. - The side-mounted snow-
brake 49, steering rails 44A-B, andribs ribs brake 49 and bring the sled to an abrupt stop. - Referring now to
FIG. 7 , side portions of the gunwale 12 are rolled outward to form alip 56. Thislip 56 curls downward to form arim portion 58 parallel to thehull 10 and separated therefrom by agap 60. Anoutboard hole 62 through therim portion 58 is aligned with aninboard hole 64 through thehull 10. Molded retainingwalls 66A-B, seem in isometric view inFIG. 8 flank theinboard hole 64 and extend outward from thehull 10, part way across thegap 60. - A
knee strap 36 has agrommet 68 at each of its two ends, one of which is shown inFIG. 9 . To attach theknee strap 36 to thehull 10, agrommet hole 70 defined by thegrommet 60 is aligned with theinboard hole 64. Then, a threaded ½inch bolt 72 is passed through thegrommet hole 70 and through theinboard hole 64. Thebolt 72 is long enough to extend through theinboard hole 64 and all the way to theoutboard hole 62. Preferably, thebolt 72 extends approximately {fraction (3/16)} inches beyond theoutboard hole 62 to ensure adequate support by the edge of theoutboard hole 62. - A
nut 74 is then threaded onto thebolt 72 to secure thebolt 72 to thehull 10. When thenut 74 is fully tightened, it comes to rest snugly between the retainingfins 66A-B, as shown inFIG. 8 . The retainingfins 66A-B thus limit rotation of thenut 74 in response to torque transmitted by thestrap 36. By doing so, the retainingfins 66A-B reduce the likelihood that thenut 74 will loosen during use. - Because of its strength, metal is typically used for making the
nut 74 andbolt 72. However, other materials such as plastic can be used. - A shear force exerted on the
strap 36 is transmitted to thehull 10 by thebolt 72. However, thehull 10 supports thebolt 72 at two different points, namely at the edge of theinboard hole 64 and also at the edge of theoutboard hole 62. As a result, the strap-anchoring configuration shown inFIGS. 7-9 resists the tendency of thebolt 72 to pivot about a single support in response to a shear force. It does so by resisting shear force using shear resistance provided by thehull 10 at two different support points. - By concealing the
nut 74 and bolt 72 from view, therim portion 58 of the lip provides thehull 10 with a more attractive and streamlined appearance. This appearance can be enhanced by coloring the end of thebolt 72 or by extending the end of thebolt 72 slightly beyond therim portion 58 so it can be capped. - In addition, by covering the
nut 74 andbolt 72, therim portion 58 also prevents thenut 74 and bolt 72 from snagging on nearby objects, such as the rider's clothing. - Referring back to
FIG. 1 , a pair of optional contouredshin pads 40 are used in combination with theknee strap 36 to maintain the axial position of the rider constant relative to thehull 10. - A
shin pad 40, a cross-section of which is shown inFIG. 14 , is a unitary structure having a raised front portion that functions as aknee stop 76 and a raised back portion that functions as afoot stop 78. Between thefoot stop 78 and theknee stop 76 is aribbed portion 80 havingtransverse ribs 82 for gripping the rider's shin. Atypical rib 82 has a vertical face that faces the rear of thehull 10 and a curved face that faces the front of thehull 10. In one embodiment, shown inFIG. 15 , the heights of theribs 82 vary to conform to the radius of curvature of the rider's shin.FIG. 16 shows an isometric view of theshin pad 40. The dimensions given inFIGS. 15-16 are selected to conform to typical adult dimensions (in inches). - The
shin pad 40 slopes downward from thefoot stop 78 to the front end of the ribbedportion 80. Past the front end of the ribbedportion 80, theshin pad 40 slopes upward to form theknee stop 76. - When a rider kneels on the
shin pad 40, as shown inFIG. 10 , the rider's knee rests on theknee stop 76 and the front of the rider's foot rests on thefoot stop 78. During sudden deceleration of the sled, deformation of theknee stop 76 and foot stop 78 absorb the rider's momentum and thereby restrain continued forward motion of the rider. - In response to the rider's weight, the
ribs 82 deform. In their deformed state, theribs 82 exert a force that tends to restore them to their undeformed state. This restoring force, when transmitted to the rider's shin, tends to grip the shin. Although the restoring force exerted by any onerib 82 is small, the collective restoring force exerted by all theribs 82 is significant. - The gripping force exerted by the
rib 82 is further enhanced by providing therib 82 with a vertical leadingface 84. In arib 82 having a sloped leading face, the rider's shin has a tendency to slide forward over therib 82. In contrast, the vertical leadingface 84 of eachrib 82 tends to resist this forward-sliding tendency of the shin. - The gripping force exerted by each
rib 82 depends, in part, on the extent of its deformation. This, in turn, depends in part on the force exerted by the shin on therib 82. This force has two components: one arising from the rider's own weight and another arising from any deceleration of the sled. Thus, one advantage of theshin pad 40 is that this gripping force increases momentarily when the sled rapidly decelerates or comes to a sudden stop. - Other embodiments of the
shin pad 40 include those havingribs 82 that extend in directions other than the transverse direction. For example, theshin pad 40 may includeribs 82 oriented in a herring-bone pattern, as shown inFIG. 11 , or diagonally, as shown inFIG. 12 . These configurations provide resistance to tangential forces that result when the sled changes turns. In addition, theshin pad 40 can have an oval footprint, as shown inFIGS. 11 and 12 , or a rectangular footprint, as shown inFIG. 13 . - The
shin pad 40 is made of a resilient material such as a closed cell foam. However, it can also be made of a molded plastic. The material used to make theshin pad 40 should be one that enables theribs 82 to deform in response to the rider's weight but to resist deformation enough to grip the rider's shin. In addition, the material should be sufficiently resilient to return to its original shape even after repeated and sustained deformation. - When manufactured out of closed cell foam, the
ribs 82 of theshin pad 40 are cut out with a heated wire. However, other methods of cutting theribs 82 of theshin pad 40, for example, with high-pressure water jets, can also be used. In other embodiments, theshin pad 40 can be molded out of a suitably resilient plastic. - The invention has been described in the context of a specific recreational racing sled. However, the various features of the invention can readily be incorporated other types of recreational sleds.
