The overall fastening situation of upper of a shoe 3 can be described now, just simultaneously in branch 19 places down and fastening at heel or ankle place.

At first, the fastening system 30 of footwear 1 has the line thigh locking device 51 of

lock wire thigh

31,32,48.Not only by like Fig. 1 and 2 but also by Fig. 3 to 8 understood, the locking device 51 of

line thigh

31,32,48 has the ducted body 52 that limits cavity 53.Cavity is defined at least one

passage

54,55 that

line thigh

31,32,48 passes through.Locking device 51 has locking member 58, and locking member 58 is movable between locked position and unlocked position, and locking device 51 cooperates with each

passage

54,55 through locking member 58 so that utilize every

line thigh

31,32,48 of snap action locking to carry out work.Elastic component 59 is actuated locking member 58 to locked position.

According to the present invention, locking device 51 acts at least three

line bodies

31,32,48.In other words, unique locking member 58 cooperates with whole line bodies, and here, all line styles such as quantity are three.Therefore, locking member 58 is fixing or unclamp institute's cable body.At locking state, institute's

cable body

31,32,48 all keeps tensioning, even if every line thigh is tightened up in a different manner.In fact, according to the tensioning state of locking device 51 retention wire bodies of the present invention.Advantageously, it is simple in structure according to locking device of the present invention 51, uses easily.

Especially as shown in Figure 3, locking device 51 has three members, and these three members are locking member 58 and the slide block or the impeller 60 of ducted body 52, circle, and slide block or impeller 60 are positioned at the outside of ducted body 52 and are connected in locking member 58 to handle said locking member.Impeller 60 activates locking member 58 translations.

Here, locking member 58 is made up of the wheel of on its periphery, being furnished with tooth 65.The center of wheel 58 has hole 66, aligns with counter boring 67 in said hole 66, and to confirm eyelet 68, said eyelet 68 is through the axle 69 of kayser admittance slide block, and said axle 69 constitutes the rotating shaft of wheel 58.Directly the axle 69 from the circle of slide block 60 has outlet side 70, and outlet side 70 is used for and takes turns 58 and be connected.This outlet side has axial crack mouth 71 on the part of its length, and has the periphery admittance groove 72 that is used to admit wheel 58.The end of outlet side has the shape of the truncated cone.Therefore, wheel 58 is installed on axle 69 rotationally.In fact, during locking, only need rotate the several years for reaching tension balance.Selectively, wheel can not rotate.

This structure allows to take turns 58 kaysers and is assembled on the axle 69.

passage

54,55 especially is shown or take turns 58 with the cooperating of these passages.

Passage

54,55 is arranged in cavity 53 along each side surface in two

side surfaces

81,82 of ducted body 52, and has groove line (strie) 83.

As shown in Figure 8, be to admit

line body

31,32,48,

passage

54,55 has the cross section that can be channel shaped cavetto shape or that formed by straight section 84.To be more clearly visible through hereinafter: this helps at locking member 58 and each passage 54, firm

grip line body

31,32,48 between 55.

According to first embodiment, the thickness e that the height h of cavity 53 equals locking member 58 adds working clearance j.Working clearance j the thickness e of locking member 58 0% to 15% between, what know is that numerical value between 2% to 7% has brought good result.The height of locking member and cavity is also corresponding to the height of two stacked line bodies.

The cavity 53 of ducted body 52 is defined for two

passages

54,55 that

line body

31,32,48 passes through; Promptly along the first passage 54 of first side surface 81 with along the second channel 55 of second side surface 82, locking member 58 is arranged in the cavity 53 and is being used between the first passage 54 and second channel 55 that line

thigh

31,32,48 passes through.Therefore, the height that each

passage

54,55 has equals the height h of cavity 53, and each passage is suitable for admitting at least two stacked line bodies.This is with

line body

31,32,48 locking member or take turns 58 and guide vis-a-vis.More precisely, here, two

line bodies

31,32 of first passage 54 guiding, the single single line body 48 of second channel 55 guiding.Make us uncannily, at locking state, as hereinafter described, even three

line bodies

31,32,48 have tensioning difference, locking device 51 also keeps the fastening of these three line thighs or locking.

For keeping every

line body

31,32,48 to contact with

passage

54,55, propose when locking member or take turns 58 when being in the unlocked position, a locking member 58 and a passage 54, the beeline between 55 cavity height h 40% to 75% between.Height h is the twice of line body diameter, or big again.This guarantees that the line body is stacked.Therefore, the first line body through port 91 and the second line body through port 92 are limited first passage 54 and second channel 55 respectively, and each all has the shape of the vertical directions extension of edge and upper surface 79 and lower surface 85 wheel 58, upper surface 79 and lower surface 85.This with two line thighs, 31,32 edges and

surface

79,85 vertical direction single line thighs above other single line thigh remain on locking member 58 places.In other words, every

line thigh

31,32 passage 54 and locking member 58 vis-a-vis simultaneously.Therefore, these line thighs are locked simultaneously or are unlocked simultaneously.

Shown in Fig. 6 and 7,

passage

54,55 is straight basically, and the direction that their irrelevancy is capable restrains on the axis of symmetry 93 of locking device 51, to intersect along direction S.

Two extreme positions that have slide block 60, the locking of the

corresponding line thigh

31,32,48 of one of them extreme position, and the release of the corresponding line thigh of another extreme position.

Locked position especially is shown in Fig. 6 and 8.

As shown in Figure 6, at locked position, the wheel 58 that is actuated along direction S all the time comes fastening these line thighs through

line thigh

31,32,48 being pressed against the bottom of the

passage

54,55 of ducted body 52.

Therefore, by

passage

54,55 with take turns 58 cooperation,, realize locking to

line thigh

31,32,48 through snap action.

The advantage of being brought through snap action locking is: the fastening value through taking turns 58

fastening line thighs

31,32,48 is proportional with the tensile force that applies on online strand, and only produces from these tensile forces.

Rotating another relevant advantage of the fact of installing with wheel 58 around axle 69 is: the tensile force F1 on the line thigh, the difference of F2 can not cause that system is blocked or can not cause the relative slip of one of line thigh with respect to locking member 58.

Especially the elastic component shown in Figure 4 and 5 also is integrated in locking device 51.This elastic component can have different shapes.

For example; Elastic component has two flexible tongue pieces 95; These two tongue pieces begin V-shaped extension from the center of slide block 60, and the free end of tongue piece 95 is arranged to be bearing on the heel 96 that the flange by ducted body 52 forms, to actuate slide block 60 along locking direction S shown in Figure 4.Certainly, tongue piece 95 also can have different shapes.

Therefore, these tongue pieces 95 also through the said axle 69 that connects together with slide block 60 that take turns, are actuated this along this locking direction S and are taken turns 58.

Therefore, locking member 58 is flexibly actuated through the locking direction of its rotating shaft 69 towards

line body

31,32,48.

Here, axle 69, slide block 60 and tongue piece 95 form single element.

The advantage that above-mentioned operation and member are obtained is to carry out accurate and quick lock wire body, and need not externally to act on locking member 58.

As replenishing, especially as shown in Figure 8, ducted body 52 has

recess

97,98 on surface and the lower surface above that respectively, and

recess

97,98 is used for when locking, conveniently ducted body 52 being met gripping of ergonomic characteristics.

Each all corresponds essentially to the finger line type trace of the

recess

97,98 of ducted body 52, and said finger is orientated to along the direction S of Fig. 6 and applies active force.

Therefore, be easier to for the user push locking device 51 with the another hand, so that move locked position on its online body up to hope with a hand drag wire body.In case reach this position, only need back-off assembly 51, and needn't apply any other action slide block, can obtain required fasteningly, the wheel 58 of being actuated by tongue piece 95 automatically applies required snap action.One advantage is to be easier to carry out locking operation.

As for unlocking operation, it only carries out with singlehanded tractive locking device 51.The said tractive of needs is actuated slide block 60 along the direction L of Fig. 7 towards unlocking direction.Therefore, unlocking operation is also more easy.

Other embodiment of the present invention is represented by Fig. 9 to 12 hereinafter.For for simplicity, indicate with identical label with the element that first embodiment has.Therefore, only the difference part is illustrated.

Second embodiment is described by Fig. 9 and 10.Therefore, see the footwear 1 with fastening system 30, said fastening system has locking device 51.
