Description

The end component of footwear
Technical field
The present invention relates to the end component of footwear, impact when particularly relating to the comfortable walking sense that can obtain having sense of stability and absorb walking and sole can be stimulated and play massage effect and then the end component of footwear of the leak of liquid being sealed in end component can also be prevented.
Background technology
When heel falls earthward when walking, the impulsive force acting on heel is about 1.25 times of body weight, and, when jogging, about 3 times of body weight can be reached.This impact is delivered to heel, ankle, knee, and then is delivered to waist, makes these positions produce burden.Further, also compared with the known impact be subject to when falling earthward with heel, impact when toe scrunches ground and lifts is larger.
Therefore, present inventors have proposed and a kind ofly can disperse to absorb the impact that is subject to when sole falls earthward when walking and can sole be stimulated and play the middle end (for example, referring to patent document 1) of massage effect.
The structure of the middle end A of the footwear shown in above-mentioned patent document 1 is described with reference to Figure 17.That is, the middle end A of the footwear described in above-mentioned patent document 1 comprises the base plate 1 similar to the shape of sole and covering 2.In addition, base plate 1 and covering 2 all use thermoplastic resin.Be formed with the 1st suitable recess 11 of the shape of landing with sole at base plate 1, be formed with 2nd recess 21 relative with the 1st recess at covering 2.
Multiple blade 3 is formed in the 1st recess 11 of base plate 1 in the mode erected integratedly.Multiple blade 3 is arranged at predetermined intervals along the direction roughly orthogonal with the length direction of base plate 1 respectively, and tilts towards heel or tiptoe.The partition wall 15 erected integratedly from this base plate is provided with between the internal perisporium 14 of the 1st recess 11 and the two ends in the transverse width direction of multiple blade 3 of base plate 1.
In addition, along the direction parallel with base plate 1 namely from when heel is viewed from tiptoe, the both ends in the transverse width direction of each blade in multiple blade 3 are formed as the roughly trapezoidal shape tilted downwards, and two places of the middle part in this transverse width direction are formed can the groove 31 of 4 movements for liquid.
Base plate 1 and covering 2, in the mutual welding in junction surface 6 place of being surrounded the periphery of the 1st recess 11 and the 2nd recess 21, are sealed with the liquid such as water, propane diols 4 in the confined space 5 clamped by the 1st recess and the 2nd recess.
Then, the effect of the middle end A of above-mentioned footwear is described.When walking, the heel portion of pin lands at first.Then, landing ground becomes large towards the outside of arch of the foot, and then body weight moves to the part (globular part (ボ ー Le portion)) of heaving of the root of toe.After body weight is carried on globular part, each toe stretches in the lateral direction, to suppress to the left and right, the rocking of front and back.Then, center of gravity forwards moves, and sole is bending from globular part, and heel part is lifted, and toe entirety scrunches ground and lifts.
In above a series of walking motion, such as heelstrike time, the pressing force brought by body weight intensively acts on the part abutted with heel of middle end A, according to so-called Pascal's law, this pressing force is delivered to all inner surfaces in this confined space equably by the liquid 4 be sealed in the confined space 5 that clamped by the 1st recess 11 and the 2nd recess 21.
Such as, but for the confined space 5 being sealed with liquid 4, when abutting with heel part, the displacement downwards of this abutment portion, pressing is positioned at the liquid 4 of this position.At this, the liquid such as water, propane diols 4 has Incoercibility, and therefore itself can not shrink.Thus, the part that the liquid 4 being such as positioned at the part abutted with heel part will not be pressed to other moves.
But the part be not pressed to other due to the liquid 4 be pressed moves, then confined space 5 will inevitably be out of shape or expand.Deform due to confined space 5 or expand, then the 1st recess 11 and the 2nd recess 21 that form the sheet of this confined space need to stretch or distortion, therefore, need the pressure increasing liquid 4.
That is, when the liquid 4 be pressed moves to the part that other are not pressed, the pressure increase of the liquid 4 in confined space 5, the part be pressed is subject to the reaction force of the pressure of this increase of liquid 4.Thus, the reaction force of this liquid 4 such as can be enough utilized to absorb the impact be subject to when heel falls earthward.
But, when middle end A does not have blade 3, such as, when heel lands, easily to all the winds moved in confined space 5 by the liquid 4 sealed, therefore, the part pressed by heel of covering 2 easily attaches on base plate 1, almost cannot relax impulsive force when heel lands.Further, when easily to all the winds being moved in confined space 5 by the liquid 4 sealed, the power that middle end A supports sole becomes unstable, and wearing feeling is deteriorated.
Such as, but when middle end A has multiple blade 3, when heel lands, the plurality of blade hinders by the movement of the liquid 4 sealed.If the movement of liquid 4 is hindered, then the resistance that the part pressed by heel producing opposing covering 2 is sunk, and become and be difficult to attach on base plate 1, impulsive force when heel lands can be relaxed.
But multiple blade 3 tilts towards heel or tiptoe.Here to multiple blade 3 towards heel situation about tilting be described, when heel lands, the liquid 4 of the part pressed by heel of middle end A in confined space 5 for moving towards tiptoe.But blade 3 tilts towards the direction of heel in the opposite direction, namely towards with the side of liquid 4 to tiptoe movement, therefore, hinders the further grow of the resistance of the movement of this liquid, thus effectively can relax impulsive force when heel lands further.
In addition, when multiple blade 3 tilts towards tiptoe, effectively can relax impulsive force when tiptoe lands further.In addition, the part in multiple blade 3 tilts towards heel, other blade tilts towards tiptoe, can impulsive force when mitigation heel and tiptoe land effectively further respectively.
Apart from the above, multiple blade 3 is formed as erecting on base plate 1 respectively, and tilts towards heel or tiptoe as described above.Thus, such as in heel pressing, during end A, bounce is produced due to the elastic force of blade 3.Therefore, on the basis of the effect of aforesaid liquid 4, the resistance that the part be pressed that the bounce of blade 3 can also be utilized to play opposing covering 2 is further sunk.
Therefore, such as, in heel pressing during end A, covering 2 is difficult to attach on base plate 1, effectively can relax impulsive force when heel lands further.Further, the power of supporting sole is stablized, and becomes the state that wearing feeling is good.
Further, when walking, the top of multiple blade 3 stimulates sole across covering 2 successively, therefore, it is possible to play the effect of massage sole.Here, when unsealing has liquid 4, the power that the top of multiple blade 3 is connected to sole across covering 2 becomes large, overstimulation sole sometimes, and produces pain.
But, when being sealed with liquid 4, the top of multiple blade 3 suitably can be suppressed to be connected to the power of sole across covering 2, therefore, it is possible to obtain comfortable massage effect by the resistance of this liquid.
As described above, the middle end A of the footwear described in patent document 1 absorbs by blade 3 dispersion of the multiple inclinations being sealed in liquid 4 in this in end and erect from base plate 1 impact that is subject to when sole falls earthward when walking and stimulates sole and play excellent massage effect.
But, for above-mentioned middle end A, when a series of action of walking or jog, when the outside of heel, arch of the foot, globular part and toe land, repeatedly have larger pressing force.Further, when a part of middle end A is pressed, the liquid 4 being positioned at this part is also pressed, and under the effect of this pressing force, is sharply increased by the pressure of airtight liquid 4.Further, the liquid 4 of the part be pressed moves rapidly to the part that other are not pressed and produces impulsive force.
Namely, when walking waits, for base plate 1 and the covering 2 of end A in formation, except tensile stress, compression stress, shear stress or bending stress, also repeatedly produce the high pressure sharply risen having liquid 4 and the impulsive force caused because of moving rapidly of this liquid.Therefore, need to take to base plate 1 and covering 2 means that prevent liquid 4 from externally leaking.Particularly need to prevent liquid 4 from revealing from the junction surface 6 between base plate 1 and covering 2.
Therefore, the present inventor is leaked in order to the liquid 4 preventing from being sealed in end A in footwear, and proposes following scheme.
Make the periphery of the 1st recess 11 of base plate 1 and the 2nd recess 21 of covering 2, be about to the thickness of slab at the junction surface 6 that both engage thickening (with reference to patent document 1 and patent document 2).This is the intensity in order to increase junction surface 6.
In addition, the width at junction surface 6 is made to be all uniform (with reference to patent document 1 and patent document 3) on complete cycle.This is the bond strength of per unit area in order to make junction surface 6 is all uniform on complete cycle, thus avoids producing the more weak part of bond strength.
In addition, between the two ends in the transverse width direction of blade 3 and the internal perisporium 14 of the 1st recess 11 of base plate 1, complete cycle is all formed with the partition wall 15 (with reference to patent document 1 reference) erected integratedly from this base plate.This is in order to avoid the liquid 4 of the movement rapidly directly impact bonded portion 6 because middle end A is pressed, and is difficult to the leakage that liquid 4 occurs.

But, even if take the above-mentioned means preventing leak of liquid, the event that liquid leaks from the junction surface between base plate and covering also can be there is.Thus, specify that to prevent the leak of liquid sealed to outside, also needing further improvement.
Summary of the invention
The present inventor is through further investigation, found that: in order to prevent the leak of liquid sealed to outside, by suppressing the sharply movement of liquid reduce the impulsive force at liquid knockout junction surface and suppress the rising of the pressure of produced local to be effective by the flowing of obstruction liquid, and complete the present invention based on this discovery.
That is, the end component of footwear of the present invention comprises base plate, covering, multiple blade and liquid.Above-mentioned base plate has the 1st region of the shape suitable with sole and surrounds the 1st all-round horizontal flanges portion in the 1st region.Above-mentioned covering has the 2nd region of the shape relative with above-mentioned 1st region and the 2nd horizontal flanges portion of the shape relative with above-mentioned 1st horizontal flanges portion.
Above-mentioned blade-shaped becomes and erects from the upper surface in above-mentioned 1st region.Above-mentioned blade is configured to spaced predetermined distance, and roughly orthogonal with the center line from toe side to heel side of above-mentioned base plate.Above-mentioned blade is by being formed by multiple plate blade elements that gap separates each other.The each above-mentioned blade of above-mentioned plate blade element tilts towards either party in toe side and heel side.
During from top view, the plate blade arrangements of components being positioned at the both end sides in the transverse width direction in above-mentioned 1st region of above-mentioned blade for towards toe side or heel side in expanding shape gradually.Above-mentioned 1st horizontal flanges portion and the 2nd horizontal flanges portion are bonded with each other and form the space by above-mentioned 1st region and the clamping of the 2nd region, and aforesaid liquid is sealed in above-mentioned space.
At this, for the material of " base plate ", " covering " and " blade ", how its kind all preferably has elasticity.Such as can adopt thermoplastic resin, heat-curing resin, synthetic rubber, natural rubber material.Further, " base plate ", " covering " and " blade " preferably adopt injection mo(u)lding or extrusion forming.And then preferably " base plate " and " blade " is one-body molded.
" shape suitable to sole " refer to walk, jog and sole under standing state lands time the roughly similar shape of shape.Preferably do not comprise the root of 5 toes and these 5 toes.
" the 1st region " and " the 2nd region " is preferably located at the depression of the concavity of the plane corresponded to each other of base plate and covering respectively, but also comprises the situation of the plane of the depression not forming concavity." the 1st horizontal flanges portion " is preferably roughly similar to the inner circumferential shape of sole respectively with the peripheral shape in " the 2nd horizontal flanges portion ", more preferably excises neighboring, is formed as larger shape in the mode that can match with the size of sole.
" gap " preferably makes blade all separate from upper end to root, but also to comprise the part making blade play more than 50% of length between upper end and root from upper end be all situation about separating.
" during from top view; the plate blade arrangements of components being positioned at the both end sides in the transverse width direction in above-mentioned 1st region of above-mentioned blade for towards toe side or heel side in expanding shape gradually " refer to, such as, when blade is made up of 4 plate blade elements, at least the two panels plate blade arrangements of components at two ends is, during from top view, be expand shape gradually towards toe side or heel side.That is, comprising remaining two panels plate blade arrangements of components is each other in expanding the situation of shape gradually and being configured to the situation both of these case of row each other.
For " footwear " in " end components of footwear ", Men's Shoes and women's shoes all comprise, and its object is sport footwear, sneak, have band or sandals, commercial affairs footwear, skiing footwear, golf footwear, sneakers, walking shoes, high leather boots, boots, shoes in doors, flip-flop, slippers and socks etc. without band.Further, " end component " comprises the so-called middle end and outer bottom.
Then, action effect of the present invention is described.Namely, the end component of footwear of the present invention utilizes the blade of the multiple inclinations being sealed in liquid at the middle end and erect from base plate in the same manner as above-mentioned conventional art, impact suffered when sole falls earthward when disperseing to absorb walking, and stimulate sole and play excellent massage effect.On the basis of the above effect, the end component of footwear of the present invention can also prevent the leakage of the liquid be sealed in this end component further effectively.
Then, the action effect of example to the leakage preventing sealed liquid such as enumerated when heel lands is described.That is, for the end component of footwear of the present invention, blade by being formed by multiple plate blade elements that gap separates each other, the plate blade arrangements of components being positioned at the both end sides in transverse width direction for from during top view towards toe side or heel side in expanding shape gradually.
Such as, when surface a part of of heel pressing covering, be positioned at this liquid being pressed position and be also pressed, sharply move to the part be not pressed in confined space.But in confined space, the spaced predetermined distance ground of multiple blade is arranged.Therefore, the movement of the liquid be pressed is hindered by the plurality of blade, and sharply moves on the transverse width direction at the middle end along interlobate gap.
At this, the plate blade arrangements of components being positioned at the both end sides in the transverse width direction of end component for from during top view towards toe side or heel side in expanding shape gradually.Thus, the liquid of the sharply movement in the lateral width direction along interlobate gap makes travel path bend owing to being positioned at the plate blade element of both end sides, tilts to flow out from the two ends in interlobate gap towards toe side or heel side.
Thus, the liquid flowed out from the two ends in interlobate gap collides the junction surface between base plate outside it and covering with the angle tilted.That is, compared with the situation of colliding orthogonally with liquid and this junction surface of movement rapidly, as long as the liquid tilt of movement rapidly collides the junction surface between base plate and covering, liquid effects can just significantly be reduced in the impulsive force of this collision part.
Further, compared with the situation of colliding orthogonally with liquid and this junction surface, as long as this liquid tilt collides the junction surface between base plate and covering, liquid just can be made sleekly to become towards heel or tiptoe direction.That is, when liquid and the junction surface between base plate and covering collide this junction surface orthogonally, the liquid of collision is difficult to flow away to heel or tiptoe direction, flows and is stopped, the static pressure colliding the liquid of part thus rises.
Thus, as long as liquid tilt collides the junction surface between base plate and covering, the liquid of collision is just easy to flow away to heel or tiptoe direction, thus the static pressure of liquid can be suppressed to rise in collision part.
In addition, blade can play following effects effect by being formed by multiple plate blade elements that gap separates each other.That is, under being configured to not establish apertured situation in the plate blade element expanding shape gradually, even if plate blade element is also not easy to bend by from top pressing, therefore excessively strong to the stimulation of sole, may pain be produced.Therefore, by arranging gap, the flexural rigidity of plate blade element can be avoided too high, and sole be carried out to the stimulation of appropriateness, play comfortable massage effect.
In addition, by arranging gap between multiple plate blade element, can be flowed out towards heel or toe side via this gap by the liquid that heel etc. presses.Thus, the speed of liquid movement in the lateral width direction along interlobate gap can be suppressed and enclose pressure, the impulsive force of liquid to junction surface can be reduced.
In addition, the multiple blade elements forming blade are formed by flat board, thus can suppress the flexural rigidity of blade element self, and carry out suitable stimulation to sole, play comfortable massage effect.
Further, with the central portion of the length direction in the 1st region of base plate for boundary, if make the incline direction of the blade being positioned at both sides, boundary line opposite each other, then heelstrike time and tiptoe scrunches, effectively can both relax impulsive force when lifting.
Therefore, in the end component of the footwear of another technical scheme of the present invention, above-mentioned multiple blade is made up of with multiple heel side blades of the scope be positioned at from this central portion to heel side multiple toe side blade of the scope be positioned at from the central portion of the length direction in above-mentioned 1st region to toe side.This toe side blade each forming multiple plate blade elements of above-mentioned toe side blade tilts towards either party in toe side and heel side respectively.
This heel side blade each forming multiple plate blade elements of above-mentioned heel side blade tilts towards the direction contrary with the incline direction of the plate blade element forming above-mentioned toe side blade respectively.During from top view, the plate blade element being positioned at the both end sides in the transverse width direction in above-mentioned 1st region of above-mentioned toe side blade is tilt with expanding shape gradually towards toe side or heel side.During from top view, the plate blade element being positioned at the both end sides in the transverse width direction in above-mentioned 1st region the tilting with expanding shape gradually in the side expanding shape gradually towards the plate blade element with the above-mentioned toe side blade of formation of above-mentioned heel side blade.
But near toe side or the blade near heel side, when from the gap trickle separated by plate blade element, the impulsive force of liquid directly acts on the junction surface being positioned at the position relative with this gap.Especially, when near toe side plate blade element towards heel side in gradually expand shape tilt, or when near heel side plate blade element towards toe side in gradually expand shape tilt, liquid flows out from gap relatively earlier, and the impulsive force of liquid is stronger.
Therefore, adopt near toe side or near the blade of heel side the plate blade element not having apertured full wafer, thus the liquid flowed out from gap can be made not produce impulsive force.
But, such as when the airtight liquid of heel pressing a part of, the liquid of the part be pressed moves up along interlobate gap in the transverse width side of base plate, flows out, collide in the junction surface between the base plate and covering in outside from the two ends in interlobate gap.Thus, only otherwise make the liquid flowed out from the two ends in interlobate gap directly collide junction surface, the leakage of liquid can just effectively be prevented.Therefore, the present inventor have employed as described in patent document 1, which such, between the two ends in the transverse width direction of blade and the internal perisporium of the 1st recess of base plate, on complete cycle, all form the means of the individual layer partition wall stood up integratedly from this base plate.
But, specify that and only not necessarily can prevent liquid from leaking from the junction surface be positioned at outside it by individual layer partition wall.That is, such as, when heel presses the liquid sealed, the part that the liquid be pressed is not pressed to other moves, and can make the seal cavity distortion of this part and expand.
Therefore, the part be not pressed, the contact portion between the upper end of individual layer partition wall and the lower surface of covering is opened, and moves to the gap that liquid here opens via this, directly collides in being positioned at the junction surface outside it.Thus, liquid easily leaks from junction surface.
Therefore, in the end component of the footwear of another technical scheme of the present invention, between the internal perisporium in above-mentioned 1st region and the both end sides in the transverse width direction of above-mentioned multiple blade, be formed with the 1st partition wall, the 1st partition wall is formed in the mode erected from the upper surface in the 1st region.Further, either party in the inner circumferential side and outer circumferential side of above-mentioned 1st partition wall, be formed with the 2nd partition wall in the position separating predetermined distance with the 1st partition wall, the 2nd partition wall is formed in the mode erected from the lower surface in above-mentioned 2nd region.
Further, the many places on above-mentioned 1st partition wall and the many places on the 2nd partition wall are respectively equipped with groove or notch part.In addition, be located at the groove of above-mentioned 1st partition wall or notch part and be located at the groove of above-mentioned 2nd partition wall or notch part is configured to, when observing from the direction of the center line along this groove or notch part, do not overlap each other.
Namely, by partition wall is set to bilayer, a partition wall is made to be formed as erecting from base plate, another partition wall is made to be formed as separating specified gap with a partition wall and vertically arranging with covering, even if thus all produce gap due to the movement of liquid between the upper end of two partition walls and the lower surface of covering, the liquid being passed in the gap of the upper end open of the partition wall being positioned at inner side also can be positioned at the root point obstruction of the partition wall in outside, therefore, it is possible to avoid directly colliding in being positioned at the junction surface outside it.
And, many places on many places on the 1st partition wall and the 2nd partition wall are respectively equipped with groove or notch part, thus the liquid flowing into the gap between the partition wall and the inner circumferential side at junction surface in outside easily flows to the inner side of the 1st partition wall, the 2nd partition wall from groove or notch part, and can avoid being enclosed in this gap, can suppress because this inclosure causes the rising of pressure.
And, be located at the groove of the 1st partition wall or notch part and be located at the groove of the 2nd partition wall or notch part is configured to, when observing from the direction of the center line along this groove or notch part, do not overlap each other, thus the liquid can avoided being pressed and flow out from the two ends in interlobate gap directly collides the junction surface between base plate and covering via groove or notch part.
