Definitions

  • the present invention relates to ski boot devices and adjustment mechanisms, and more particularly, to ski boot tightening and loosening mechanisms and processes.
  • a ski boot has a fairly rigid outer structure that helps prevent a skier’s foot from moving within the ski boot while the skier is skiing.
  • a skier When putting on or taking off a ski boot, a skier often needs to forcefully push or pull his or her foot into or out of the ski boot, and to try different positions (e.g., sitting, standing, and switching between sitting and standing) while attempting to put on or remove the ski boot.
  • mechanical straps used to tighten or loosen the ski boot tend to require a lot of force to disengage and/or reset them. The skier generally needs to stretch, bend, and manually manipulate the ski boot straps every time he or she wishes to adjust the fit of the ski boot.
  • adjustable straps can be manipulated to change the fit of the ski boot, they are sometimes set in a configuration which is either too loose or too tight for walking or skiing. This can occur when initially putting on the ski boot or while skiing as pressure inside the boot changes. Straps that are too tightly set can cause shin pain when the skier walks around in the ski boots because the shin portion of the outer rigid structure of the boot presses against the skier’s shin. Straps that are too loosely set can cause the skier’s foot to slide around within the boot while walking or skiing.
  • Incrementally changing conventional ski boot strap settings to the next highest or lowest setting to increase or decrease the pressure of the fit of the ski boot about the skier’s foot/leg may inadvertently overly tighten or overly loosen the ski boot.
  • the incremental change in the strap may undershoot or overshoot a skier’s desired pressure level.
  • a skier who is outside and wishes to adjust a ski boot often has to stretch, bend, and manually manipulate these straps while standing on snow, ice, or other slippery surfaces, which can be dangerous.
  • Putting on, removing, and adjusting conventional ski boots can thus be an arduous process, whether inside or outside, and particularly for older, handicapped, disabled, and/or injured people with limited flexibility and range of motion.
  • a ski boot adjustment system includes an adjustment mechanism configured to tighten and loosen a portion of a ski boot, at least one triggering device configured to selectively actuate the adjustment mechanism, and a controller mounted within the ski boot and configured to monitor pressure in the portion of the ski boot during operation of the adjustment mechanism.
  • a ski boot adjustment system includes an adjustment mechanism configured to tighten and loosen a portion of a ski boot, and a triggering device configured to actuate the adjustment mechanism.
  • the triggering device is operatively disposed in a mat adjacent at least one of an entrance to a building or a parking location.

  • the present invention allows a skier to easily tighten, loosen, and customize ski boots or snowboard boots with minimal effort, while standing or sitting, indoors or outdoors, and with little to no stretching, awkward bending, or pulling. While the invention may be utilized for different types of boots, it is particularly useful for both ski boots and snowboard boots because these types of boots are tight-fitting during use. Rather than bending and reaching toward ski boots in physically awkward or uncomfortable positions and manually manipulating rigidly applied straps, the skier is instead able to tighten and/or loosen different sections of his or her ski boots using localized or remote triggers which actuate tightening and loosening mechanisms within the ski boots.
  • Different types of tightening and loosening mechanisms are utilized, including, for example, inflatable and deflatable air bladders, motorized adjustable straps, and the like.
  • Various types of triggering mechanisms are also utilized, including, for example, manually operated push buttons on the ski boot, an app running on the skier’s mobile device, a mat the skier can step onto, and particular orientation(s) or movement(s) of the ski boots which the skier can pre-set.
  • the ski boot tightening and loosening devices, techniques, triggering mechanisms, and control features of the invention make skiing and snowboarding easier and more enjoyable for skiers of all ages and abilities.
  • the invention provides the skier with the ability to easily make pressure adjustments by simply moving the ski boot with his or her foot in particular preset motion(s) and/or orientation(s) to trigger tightening and loosening operations.
  • the skier is able to individually control and adjust pressure in different regions of the ski boot through graphical user interfaces, view data in real-time (e.g., existing pressure readings in the boot and/or pre-set pressure configurations), and control different ski boot functionalities.
  • the skier can make adjustments while skiing throughout the day as temperature and/or pressure conditions change within the ski boot.
  • the external triggering devices such as the step-on mat make it easier for the skier to loosen or tighten ski boots upon entering or exiting a ski lodge, or upon returning to his or her car.

  • Pump 127 may extend through outer shell 121, and be used to manually inflate air bladder 119 responsive to repeated depression of convex push button 140a by the skier.
  • Pump 127 may be configured with a duckbill one-way valve, whereby depression of push button 140a forces air into interior chamber 131 of air bladder 119, but does not allow air to exit interior chamber 131.
  • Convex push button 140a may be spring biased toward the convex position of FIG. 3, such that when the skier releases push button 140a, it springs back from the configuration of FIG. 4 to the configuration of FIG. 3 without allowing air to escape from interior chamber 131 of air bladder 119.

  • triggering devices 140a, 140b can simply be fluidly coupled with an interior region of shell 121, and not with an air bladder separate and apart from outer boot shell 121. Over the course of a day, if ski boot 130 begins to feel too tight or too lose, the skier can simply press triggering push buttons 140a, 140b to inflate or deflate air bladder 119 to increase or decrease the pressure of the fit of ski boot 130.
  • controller 128 may be included with ski boot 130, and programmed to monitor whether pressure readings from pressure sensor 129 fall within a preset range. If the pressure readings fall within the preset range, then controller 128 may be configured to actuate light 132 (powered by power source 150) to signal to the skier that the pressure level is appropriate for skiing. Light 132 may be configured to shine in different colors, and be controlled by controller 128 to blink and/or show different colors depending on whether the pressure level set by the skier is too high, too low, or within preset acceptable ranges. Controller 128 may be set with these present ranges either remotely or through one or more mechanical switches (not shown) electrically coupled to controller 128 and disposed on light 132 or mounted on an outer wall of ski boot 130. It will be appreciated that this embodiment allows the skier to easily customize and adjust the pressure setting in ski boot 130 without undoing or resetting straps 152, 154, 156, 158, and without extensive stretching, bending, or application of forces thereto.

  • One way to ensure that controller 228 correctly understands a skier’s specific intention to inflate or deflate the air bladders is to set a relatively large time period (e.g., ten to fifteen seconds or thirty seconds) for holding a particular orientation of the ski boot 230, and/or requiring that the ski boot 230 be moved through one or more unusual motions as the trigger for starting inflation or deflation. For example, rapidly turning the ski boot 230 clockwise, then counterclockwise, and then repeating these intermittent clockwise and counterclockwise motions for a predetermined period of time, may signal to controller 228 an intention to inflate or deflate the air bladders. Other orientations and motions may be utilized.
  • Motion sensors/gyroscopes G1-G4 and controller 228 may be configured to detect rapid and/or repeating accelerations (speed and/or directional changes), whereby the controller 228 can ascertain an intention by the skier to inflate or deflate based on the unusual motions of the ski boot 230.

  • Controller 228 may also be configured to prevent loosening (e.g., to keep air bladders 224A, 224B, 224C, 224D inflated to at least a certain level) if ski boot 230 is locked into a ski binding, regardless of the orientation of ski boot 230 or movement instruction by the skier. In such embodiments, once ski boot 230 is unlocked from the ski binding, deflation may be allowed. Such configurations of controller 228 would prevent inadvertent loosening of ski boot 230 while the skier is on a chairlift or in another seated position, and/or when a skier inadvertently makes an inflation or deflation motion or orientation with ski boot 230 in any other location. Controller 228 may also be wired to a switch 270 on the exterior of boot 230 to enable a skier to manually turn on and off automated inflation and deflation control by controller 228. Other manual overrides may be utilized, such as a child safety switch.
  • Light/light sensor 232 may be configured as an LED or other form of light, visible or invisible, with or without light sensing capability, and may be emitted from a portion of front foot region 212. Controller 228 may be configured to monitor inputs from light/light sensor 232. For example, if light 232 is covered for a predetermined period of time, such as by the skier placing front foot region 212 of ski boot 230 into snow, then light 232 may signal controller 228 that inflation or deflation is desired. Light/light sensor 232 can also function to provide visibility to the skier when skiing at night.
