Definitions

  • This invention relates toski fastenings, and particularly to such fastenings in which the tensioning lever to which the heel strap is attached is articulated to a longitudinally displaceable slide.
  • One object of the invention is to permit quick adjustment and tightening of the heel strap by simple and .reliable means.
  • Anotherobject of the invention is a simple and compact arrangement of the tensioning device, permitting.
  • a still further object of the invention is to attain relatively less strain on the material of the tensioning device and the heel strap and a better fitting of these parts by preventing them from undesirable movements.
  • a feature of the invention consists in that the slide is provided with a device for coarse adjustment of the heel strap and also with a device for fine adjustment.
  • this slide may be constucted in two parts in such a manner that one part cooperates with rack devices on the slideguide for coarse adjustment of the slide, while the other part carries the tensioning lever and is displaceable relatively to the first-mentioned part for fine adjustment of the heel strap in the longitudinal direction of the slide, preferably by means of a threaded screw.
  • the slide is provided with a locking member rotatable about a longitudinal axis and movable into engagement with spaced racks in the slide guide for the purpose of coarse adjustment of the slide.
  • the rotatable locking member provided for the coarse adjustment may be secured against movement out of its locking position by the tightening lever, which may for example cover over and protect the locking member.
  • the two tension springs arranged at both sides of the tensioning device have their ends remote from said device connected together by a transverse member which can be made, for example, in its simplest form, of flat strap.
  • the transverse member in such case, on relaxing the tension on the heel strap, acts to prevent the latter from moving undesirably sideways.
  • the heel strap is prevented from coming out of place and thus, for example, from twisting the springs inserted in the heel strap.
  • Fig. l is a longitudinal sectional view through the tensioning part of the ski fastening.
  • Fig. 2- is a plan view of the same section on the line 16 and 17 for a cable 18-which serves as the heel strap.
  • I is mounted an externally knurled disc 31 which is rotatable about the axis of the screw 13 and bush 24.
  • Fig. 4 is a section on line 4-4 of Fig.1 with the tensioning slide locked and the tensioning lever turned downwards.
  • Fig. 5 is a section on line 5-5 of Fig. 1 with the tensioning lever raised as in Fig. 1.
  • Fig. 6 is a plan view of another form of the fastening.
  • Fig. 7 is a plan view of a third form of fastening.
  • Fig. 8 is a longitudinal section of a fourth form.
  • Fig. 9 is a longitudinal section of a fifth form of the invention.
  • Fig. 10 is a plan view of the form shown in Fig. 9. h
  • Fig. ll is a plan view of a further form of the rotating part.
  • Figs. 12 and 13 are front views of two constructions of cross members connectingthe ends of the springs.
  • Figs. 14 and 15 show in side view and plan view, respectively, the heel strap loop for a ski boot and the manner in which the device of the present invention is fixed to a ski.
  • the tensioning device comprises essentially a guide part 10 for' the tensioning slide, ,two slide parts 11 and 12, which are connected together by a fine adjustment screw 13, and a lever 14, which is pivoted by means of the transverse pin 15 on the slide part 12 and carries tension springs
  • the guide 1% consists of a base plate 19 having holes 20, 21 therein which serve for fastening the 1 base plate to the ski by means of suitable screws.
  • uide 11 is providedwith side guide cheeks 22, 23, which, as seen particularly in Fig. 5, form an approximately dovetail-shaped guide for the slide parts 11, 12.
  • side guide cheeks 22, 23, which, as seen particularly in Fig. 5, form an approximately dovetail-shaped guide for the slide parts 11, 12.
  • slide part 11 embraces an internally threaded bush 24 fixed in a guide element 27 which is partly slotted and is of inverted U-shape having lateral flanges 25 and 26, the fine adjustment screw 13 being screwed into the bush 24.
  • One end of the screw 13 is rotatable by means of a head 28 in the slide part 12 and the other end is provided with a knob 29 for hand adjustment, the arrangement being such that, on turning the fine adjustment screw 13 by means of the knob, the distance of the slide part 12 from the slide part 11 can be varied.
  • the disc 31 forms at one side an overlapping projecting locking device 32 which can be engaged in slots 33, 34 in the guide cheeks 22, 23.
  • the lever 14 articulated to both sides of the slidepart 12 by the pin 15 is of U-shaped cross sectionand is provided in both of its side walls with hook-shaped slots 1 35 through which passes a transverse element .or member 36 for attaching the springs 16, 17 of the heel strap.
  • the transverse element 36 may be soldered to the ends 5 of the springs 16, 17 or connected to them in. any other manner. Also, it may itselfbe made of spring wire, in which case both springs 16 and 17 can be madefrom a.
  • the transverse element36 as seen particularly in Figs. 4 and 5, is bent upwards in the middle so that in the closed position of the lever (Fig. 4) it does single length of wire.
  • the lever 14 are slotted at 37 so that the lugs resulting at both sides of the slots can be bent laterally withouti difficulty for fitting the element 36 in position; after which the lugs can be bent back again into theinoriginal-ii Patented Apr. 17,1956:
  • planeandzthus prevent the element 36 from springing out of'position.
  • the coarse or fine adjustment of the fastening is eifected in the raised position of the lever 14.
  • the locking disc 31, 32 is turned from engaging the slots 33, 34, for instance into the positionshown in Fig. 3, whereupon both Slide parts 11 and 12 can be moved to gether in the longitudinal direction of the slide device.
  • five coarse adjustments are possible corresponding to five slots 33 or 34, so that the locking disc 31 can be brought into line with any desired pair of the five slots 33, 34 at one movement and can thereupon be turned untilxthe locking part 32 engages the relative notches 33, 34 (as in Fig. 4').
  • the fine adjustment screw 13 can then be turned by means of the knob 29, when the slide part 12 with the lever 14 is caused to approach or recede from the slide part 12. After adjustment, the lever 14 is turned down into the position 14, whereby at the same time it secures the locking'disc 31 in the adjusted position (Fig. 4) and also covers the knob 29.
  • the element 36 can also be adjusted within the slots 35 from the position 36' to the position 36", which can be effected if necessary by simply swinging over the element 36 with the lever 14 raised. The securing is then effected similarly by folding down the lever, when the transverse element 36 now embracing the fine adjustment screw 13 is held in the position 36' or 36".
  • the heel strap tensioning device is directly attached to the lever, for example, by riveting.
