  • a closure device comprising a pair of pull members coupled each to one of the closure flaps at one end thereof, a central member comprising a rotatably mounted disc at least partially formed as a maltese cross having leg portions with recesses formed between adjacent leg portions and groove means formed on the leg portions, a driving member disposed adjacent the disc and having pins formed thereon, the pins during rotation of the driving member engaging a predetermined one of the groove means, a cam member on the driving member having convexly shaped end portions for engagement with a predetermined one of the recesses formed on the ma]- tese cross shaped disc and forming a latch therewith, the cam member having concavely shaped side surfaces connecting the end surfaces for allowing unimpeded passage of the end portions of the legs of the disc during rotation of the disc by the pins, whereby a rotation of the driving element causes the
  • the present invention relates to a closure device for shoes, especially for ski shoes, in which on the edge portions of the closure flap of the shoe which are to be pulled together, pull members or straps are secured and such pull members are jointedly coupled with a rotatably mounted disc lying between the straps, such coupling being in an off-centered fashion and in such a manner that during the rotation of the disc the pull straps are either pulled in or pushed outwardly.
  • a shoe closure means is characterized in that the above-mentioned rotatably mounted disc at least in portions is formed as a maltese cross and that the pull members or straps are coupled with the disc by connecting straps and wherein on the leg portions of the maltese cross radial guide groove means are provided into which pin means disposed in an off-center fashion on a driving member are adapted to enter; such driving member being rotatably mounted in a plane parallel with respect to the plane of the disc, and when rotated, the pins operatively engage the groove means; the driving member including a pair of pin means and a cam member having a pair of convexly shaped front or end surfaces which, during the rotation of the driving member, alternately engage recess means formed on the maltese cross with a radius similar to those of the convex end portions of the cam member and being retained therein to form a latch means together with such recess means and define a rest position of the closure device thereby.
  • the disc which is formed as a maltese cross is preferably a circular disc with two leg portions, and consequently it has three recess means formed thereon which, in turn, allow for three rest or intermediate positions of the pull member as hereinafter described. If two leg portions are formed on the maltese cross with a displacement of 60 with respect to each other, then the disc has also two guide grooves formed thereon for engagement with the pin means of the driving member.
  • the driving member has a round disc and only a single pin means formed thereon, then in order to arrive from one of the three rest positions of the closure means to another rest position thereof, there will be necessary a full rotation of the driving member.
  • a pair of pin means it is sufficient that a rotation of 180 takes place between adjacent rest or latch position.
  • the driving member preferably is provided with a pair of pin means which are lying opposite each other.
  • the camming member between its two convex end or front surfaces has concave side surfaces on each side connecting the front surfaces which, during the rotation of the disc, allow entry of the sharp end corners of the leg portions of the maltese cross and an unimpeded passing of them over such concave surfaces.
  • the closure device is placed in a housing.
  • the shoe closure device is characterized in that the pull members or straps are secured on the edge portions of the closure flaps of the shoe by means of retaining devices in a releasable fashion, and that the center closure member is secured at one end of a tiltable toungue which, in turn, at the other end thereof is secured in the region of the upper of the shoe where the separation of the closure flaps of the shoe begins.
  • the latter embodiment of the ski shoe closure device according to the' present invention has the advantage that a skier can close or open his shoe by means of an individual or single closure member.
  • the closure flaps of the shoe are pulled apart and the center closure element of the closure device is open; then he flips the tongue back into its position, whereupon the pull straps or members of the closure device will engage the retaining devices or portions provided on the edge portions of the closure flaps, and then he pulls together the pull members or straps of the closure device by operating the center closure element of the closure device.
  • the above described operational steps are performed in the opposite direction.
  • the shoe can be latched in an intermediate position of the closure element in such a manner as the skier may desire, for example, for the downhill skiing. In this intermediate position the pull members or straps remain still in engagement with the retaining portions on the edges of the shoe flaps. The same holds true also for the center closure element having four rest positions.
  • the retaining or securing members of the flap of the shoe can be provided, for example, with a button means which enters into an opening on the free or unsecured end of the pull members or straps and becomes secured to the pull members or straps in this manner. It is also possible and within the scope of the present invention that the retaining or securing members are provided with two or more button means.
  • the free or unsecured ends of the pull members or straps are formed in a hook shape and cooperate with the appropriately formed, that is, hook-shaped retaining or securing members on the flaps. It can be advantageous to shape the retaining or securing members resiliently in the pulling direction by means of a metallic spring or a rubber-like resilient element.
  • the shoe tongue can be made of leather, synthetic material or metal. In the latter case it is preferably provided with a hinge means. Even if the tongue is made of leather or synthetic material, it still can be provided by a hinge means. It is also within the scope of the present invention to provide that if the tongue is made of metal, it is preferably covered with leather or with a synthetic material or similar material.
  • the forwardly tiltable toungue should be provided on each side thereof with a bellows-like sealing flap which can be extended or returned to a compressed state with the flapping or closing of the shoe tongue.
  • the pull members or straps and the connecting rod-like coupling element are replaced by a pull cable.
  • the securing or retaining member on the flaps of the shoe can be provided with a button which can enter into a lug means provided on the free or unsecured end of the pull cable and thereby be coupled with the pull cable.
  • the free ends of the pull cable are fixedly coupled with a nipple and cooperate with appropriately shaped retaining members.
  • the retaining members in the pull direction can be made resilient by means of a metallic spring or by means of a rubber-like resilient element.
