Abstract
Closure device particularly for sports shoes including a shell and a quarter and provided with a first flap and a second flap to be secured or with straps to be tensioned and secured. The device includes grip elements and at least one engagement element which are associable respectively with the first flap and with the second flap, or with the shoe and with the band. The grip elements selectively and detachably interact with the engagement element by using an auxiliary lever. The device has low manufacturing costs, allowing to standardize the individual components and limiting protrusions with respect to the surfaces of the shoe.
Claims20
Closure device for releasably mutually securing a first portion and a second portion of a sports shoe, wherein the closure device comprises grip elements which are associable with the first portion and which selectively and detachably interact, by means of an auxiliary lever, with at least one engagement element which is associable with the second portion, and wherein each of said grip elements comprises a base which is associable with the first portion, multiple mutually parallel first seats being provided transversely on said base, and wherein a first tab protrudes at each one of said first seats towards a facing surface of said first portion, and wherein said engagement element is constituted by a pawl which has a first tooth directed towards said first portion when said first tooth selectively and detachably interacts with a respective first seat.
A closure device for releasably securing a first portion and a second portion of a sports shoe, the closure device comprising:
- a grip element rigidly and non-pivotally connectable with the first portion of the sports shoe;
- an engagement element rigidly and non-pivotally connectable with the second portion of the sports shoe;
- a plurality of selectable detachable engagement positions between said grip element and said engagement element, each of said selectable detachable engagement positions comprising a releasable arrangement of a tooth element rigidly and non-pivotally formed at one of said grip and engagement elements which is detachably engaged in abutment with a holding element rigidly and non-pivotally formed at the other of said grip and engagement elements such as to selectively and mutually releasably secure the first and second portions of the sports shoe;
- a lever device adapted for engaging said engagement element such as to move said engagement element relative to said grip element to selectively form a selected one of said plurality of engagement positions between said grip and engagement elements, said lever device being detachable from said sports shoe and comprising a pivoting lever arm and a traction element connected to said pivoting lever arm such that said traction element is engageable with said engagement element while simultaneously a pivoting action of said lever arm selectively forms said selected one of said plurality of engagement positions between said grip and engagement elements, said lever device being detachable from said sports shoe such that after said selected one of said plurality of engagement positions between said grip and engagement elements is formed said lever device is detachable from said sports shoe.
A closure device for releasably securing a first portion and a second portion of a sports shoe, the closure device comprising:
- a grip element connectable with the first portion of the sports shoe;
- an engagement element connectable with the second portion of the sports shoe;
- a plurality of selectable detachable engagement positions between said grip element and said engagement element, each of said selectable detachable engagement positions comprising a releasable arrangement of a tooth element formed at one of said grip and engagement elements which is detachably engaged in abutment with a holding element formed at the other of said grip and engagement elements such as to selectively and mutually releasably secure the first and second portions of the sports shoe;
- a lever device adapted for engaging said engagement element such as to move said engagement element relative to said grip element to selectively form a selected one of said plurality of engagement positions between said grip and engagement elements, said lever device being detachable from said sports shoe and comprising a pivoting lever arm and a traction element connected to said pivoting lever arm such that said traction element is engageable with said engagement element while simultaneously a pivoting action of said lever arm selectively forms said selected one of said plurality of engagement positions between said grip and engagement elements, said lever device being detachable from said sports shoe such that after said selected one of said plurality of engagement positions between said grip and engagement elements is formed said lever device is detachable from said sports shoe;
- wherein said lever device further comprises a wing element pivoted to said lever arm and adapted for engaging an abutment element of said grip element which holds the wing element during the pivoting action of said lever arm.
A closure device for releasably securing a first portion and a second portion of a sports shoe, the closure device comprising:
- a grip element rigidly and non-pivotally connectable with the first portion of the sports shoe;
- an engagement element rigidly and non-pivotally connectable with the second portion of the sports shoe;
- a plurality of selectable detachable engagement positions between said grip element and said engagement element, each of said selectable detachable engagement positions comprising a releasable arrangement of a tooth element rigidly and non-pivotally formed at one of said grip and engagement elements which is detachably engaged in abutment with a holding element rigidly and non-pivotally formed at the other of said grip and engagement elements such as to selectively and mutually releasably secure the first and second portions of the sports shoe;
- a lever means for engaging said engagement element such as to move said engagement element relative to said grip element to selectively form a selected one of said plurality of engagement positions between said grip and engagement elements, said lever means being detachable from said sports shoe and comprising a pivoting lever arm and a traction element connected to said pivoting lever arm such that said traction element is engageable with said engagement element while simultaneously a pivoting action of said lever arm selectively forms said selected one of said plurality of engagement positions between said grip and engagement elements, said lever means being detachable from said sports shoe such that after said selected one of said plurality of engagement positions between said grip and engagement elements is formed said lever means is detachable from said sports shoe.
A closure device for releasably securing a first portion and a second portion of a sports shoe, the closure device comprising:
- a grip element connectable with the first portion of the sports shoe;
- an engagement element connectable with the second portion of the sports shoe;
- a plurality of selectable detachable engagement positions between said grip element and said engagement element, each of said selectable detachable engagement positions comprising a releasable arrangement of a tooth element formed at one of said grip and engagement elements which is detachably engaged in abutment with a holding element formed at the other of said grip and engagement elements such as to selectively and mutually releasably secure the first and second portions of the sports shoe;
- a lever means for engaging said engagement element such as to move said engagement element relative to said grip element to selectively form a selected one of said plurality of engagement positions between said grip and engagement elements, said lever means being detachable from said sports shoe and comprising a pivoting lever arm and a traction element connected to said pivoting lever arm such that said traction element is engageable with said engagement element while simultaneously a pivoting action of said lever arm selectively forms said selected one of said plurality of engagement positions between said grip and engagement elements, said lever means being detachable from said sports shoe such that after said selected one of said plurality of engagement positions between said grip and engagement elements is formed said lever means is detachable from said sports shoe;
- wherein said lever means further comprises a wing element pivoted to said lever arm and adapted for engaging an abutment element of said grip element which holds the wing element during the pivoting action of said lever arm.
