Definitions

  • This invention relates to a flex adjusting device particularly for rear entrance ski boots.
  • rear entrance ski boots are finding ever increasing popularity comprising, in their commonest form, a shell having front and rear quarters connected thereto.
  • Prior devices tend to be excessively bulky, difficult to adjust, and unable to provide for continuous and quick control of the amount of flex.
  • a further object of the invention is to provide such a device which can also be adjusted in adverse environmental conditions, such as are normally encountered in the skiing field,even by a person donning mittens.
  • a flex adjusting device particularly for rear entrance ski boots, according to the invention, characterized in that it comprises a friction element associated with the bottom surface of the front quarter of a ski boot and acting in rubbing contact with a backplate attached to the shell of said ski boot, adjustable calibration elastic means being also provided to control the contact pressure between said friction element and said backplate.
  • a flex adjusting device particularly for rear entrance ski boots comprises a friction element comprising a friction plate 1 which is located below the toe portion of the front quarter 2 of a ski boot. More in detail, in the embodiment shown in Pigures 1 and 2, the friction plate 1 is located at the front upper portion of the boot, at a front projection 3 defined by the quarter itself.
  • the cited friction plate 1 is associated with the shank 4 of a throughgoing pin which has its enlarged head 5 located inside the shell 6.
  • the shank 4 is passed slidably through an elongate slot 7 defined in the front upper portion of the shell 6.
  • the shank 4 has, at its other end, a threaded portion 8 wherewith a control knob 9 engages rotatably which acts at the top of said front quarter 2, at the projection or protuberance 3 thereof.
  • the cited friction plate is in rubbing contact with a backplate 10 located on the shell 6 and being connected to the shell by fastening means comprising rivets 11 or the like elements.
  • the backplate 10 is also formed with the throughgoing slot 7 to allow for the sliding movement of the shank 4.
  • elastic means are active which comprise a pair of juxtaposed disk springs 12 applying an elastic thrust which in practice controls the contact pressure between the friction plate 7 and backplate 10, thus practically adjusting the braking action applied between the front quarter 2 and shell 6 during the flexing movement.
  • the flex adjusting device is positioned laterally of the front quarter, and has a friction element comprising a friction plate 20 connected to a small supporting plate 21 attached, as by means of rivets 22 or the like elements, to a protuberance 23 defined on the quarter.
  • the shell 6 is advantageously formed with a cutout 32 to avoid interference with the enlarged portion.
  • the shank 24 has, at its other end, a threaded portion 35 wherewith an adjustment ring nut 36 engages which is aocessable from the outside of the protuberance 23 and acts against elastic means comprising a bell-like spring 40 carried directly on the supporting plate 21.
  • the spring 40 is compressed to a greater or lesser extent, thus varying the pressure exerted by the friction plate 20 on the friction backplate 30.
  • a friction plate 50 associated with the shell is a friction plate 50, defining a varying thickness along the direction of longitudinal development, which preferably increases in thickness toward the shell toe end.
  • the plate 50 defines an elongate slot 51 wherethrough a threaded stem 52 is passed which has an enlarged end portion 53.
  • the stem 52 is passed through a lower friction disk 54 and upper friction disk 55, which are in rubbing contact relationship with the plate 50 and supported on the quarter 2. Further, the stem 52 engages in a threaded receptacle 56 defined in a gripping element 57 carried rotatably on the quarter 2.
  • elastic means comprising an adjustable calibration spring 60 which can be calibrated by operating the grip 57 to cause the stem 52 to translate, thereby varying the frictional force applicable between the plate 50 and disks 54,55.
  • the plate 50 has at least one inclined surface, and the contacting disk correspondingly presents a matching juxtaposed inclined surface.
  • the use of the device according to the invention is quite simple.
  • the user is simply required to adjust the knob 9 or ring nut 36 or grip 57 in conformity with his/her own requirements by applying a desired compression of the elastic means and hence adjusting the frictional pressure between the friction plate 1 and backplate 10 or between the friction plate 20 and friction backplate 30 or between the plate 50 and disks 54 and 55, thus changing flexure as required with an action which practically varies the frictional pressure between parts in mutual rubbing contact.
  • the invention achieves its objects, and in particular the fact should be pointed out that a device has been provided whereby the flexibility can be adjusted in an extremely simple and quick manner through the utilization of the friction differential, occurring as the applied pressure is varied, between a friction plate and respective backplate attached to the boot shell.
  • any materials, dimensions and contingent shapes may be any selected ones and used to meet individual requirements, providing that they are compatible with the specific intended application.
