Boot, in particular ski boot, with a monolithic structure

Claim 2

A boot structure of monolithic type comprising, an enbloc body defining a shell portion and a front quarter portion integral therewith, a rear quarter hinged to said shell portion, said front quarter portion and said rear quarter defining a leg area having a front part of the leg area and a rear part of the leg area, a tiltable internal quarter facing internally said front quarter portion and having a lower end portion connected to said body and extending at least over the front part of the leg area, closing means including an actuating mechanism fixed on the rear quarter and transmission means for transmitting the actuating action of said actuating mechanism, wherein said transmission means have at least one end portion thereof fixed to said internal quarter and at least another opposite end portion connected to said rear quarter through said actuating mechanism thereby to tilt said internal quarter towards said rear quarter through a first tilting angle when said actuating mechanism is actuated to close said boot, and wherein said one end portion of said transmission means includes engagement means for slidably engaging within limits said front quarter portion, said front quarter portion having stop means defining said limits of slidable engagement between said engagement means and said front quarter portion, thereby to tighten said front quarter portion towards said rear quarter portion when said closing action on said actuating mechanism is continued beyond said first tilting angle and said engagement means reach said stop means.

Claim 3

A boot according to claim 1, wherein said internal quarter is made enbloc with said body and wherein said internal quarter branches internally from said front quarter portion at said front part of said leg area.

Claim 4

A boot according to claim 1, wherein said internal quarter includes lateral slots.

Claim 5

A boot according to claim 1, wherein said internal quarter defines, in cooperation with said front quarter portion, an internal space for the housing of mechanisms for the adjustment of the boot.

Claim 6

A boot according to claim 1, wherein said transmission means comprise at least one cable and wherein said one end portion of said transmission means is a pin connected with said cable and fixed on said tiltable internal quarter, wherein said stop means comprise at least one slot in said front quarter portion, said slot extending in the direction towards said rear quarter and having abutment ends defining said limits of slidable engagement and wherein said engagement means comprise a pin formation projecting from said pin and extending into said slot for slidable engagement within limits therein, said limits defining the length of the stroke performed by said pin formation within said slot.

Claim 7

A boot according to claim 5, wherein said pin formation rigid with said tiltable internal quarter has adjustment means for adjusting the length of said stroke defined by the distance between said abutment ends of said slot, one of said abutment ends being nearer to said rear quarter than the other of said abutment ends.

Claim 8

A boot according to claim 6, wherein said adjustment means comprise a threaded hole in said pin formation and a threaded dowel rotatably engageable in said threaded hole and in engagement with said one of said abutment ends when said tiltable internal quarter is tilted towards said rear quarter beyond a preestablished tilting angle.

Claim 9

A boot structure of monolithic type comprising, an enbloc body defining a shell portion and a front quarter portion integral therewith, a rear quarter hinged to said shell portion, said front quarter portion and said rear quarter defining a leg area having a front part of the leg area and a rear part of the leg area, a tiltable internal quarter facing internally said front quarter portion and having a lower end portion connected to said body and extending at least over the front part of the leg area. closing means including an actuating lever mechanism fixed on the rear quarter and cable means for transmitting the actuating action of said actuatung lever mechanism, wherein said cable means have at least one end portion thereof fixed to said internal quarter and at least another opposite end portion connected to said rear quarter through said actuating mechanism thereby to tilt said internal quarter towards said rear quarter through a first tilting angle when said actuating mechanism is actuated to close said boot, and wherein said one end portion of said cable means includes a pin structure for slidably engaging within limits said front quarter portion, said front quarter portion having at least one arcuated slot having abutment ends defining limit stop means for determining the stroke extent of slidable engagement portion, thereby to tighten said front quarter portion towards said rear quarter portion when said closing action on said actuating lever mechanism is continued beyond said first tilting angle and said pin structure reaches said stop means.

Claim 10

A boot structure of monolithic type comprising, an enbloc body defining a shell portion and a front quarter portion integral therewith, a rear quarter hinged to said shell portion, said front quarter portion and said rear quarter defining a leg area having a front part of the leg area and a rear part of the leg area, a tiltable internal quarter facing internally said front quarter portion and having a lower end portion connected to said body and extending at least over the front part of the leg area. closing means including an actuating lever mechanism fixed on the rear quarter and cable means for transmitting the actuating action of said actuatung lever mechanism, wherein said cable means have at least one end portion thereof fixed to said internal quarter and at least another opposite end portion connected to said rear quarter through said actuating mechanism thereby to tilt said internal quarter towards said rear quarter through a first tilting angle when said actuating mechanism is actuated to close said boot, and wherein said one end portion of said cable means includes a pin structure for slidably engaging within limits said front quarter portion, said front quarter portion having at least one arcuated slot having abutment ends defining limit stop means for determining the stroke extent of slidable engagement portion, thereby to tighten said front quarter portion towards said rear quarter portion when said closing action on said actuating lever mechanism is continued beyond said first tilting angle and said pin structure reaches said stop means.

Claim 11

A boot according to claim 8, wherein said pin structure rigid with said tiltable internal quarter has adjustment means for adjusting the length of said stroke extent defined by the distance between said abutment ends of said slot, one of said abutment ends being nearer to said rear quarter than the other of said abutment ends.

Claim 12

A boot according to claim 6, wherein said adjustment means comprise a threaded hole in said pin structure and a threaded dowel rotatably engageable in said threaded hole and in engagement with said one of said abutment ends when said tiltable internal quarter is tilted towards said rear quarter beyond a preestablished tilting angle.
