In certain embodiments, the pressure pad that forms the part of the footwear insert invented can comprise the combination of material.For example, pressure pad can comprise first material that is covered at least in part or coated by second material.In a further embodiment, pressure pad can comprise a plurality of layers.Preferably, at least a portion of pressure pad comprises gel rubber material.In certain embodiments, can comprise gel rubber material according to pressure pad of the present invention and surround and coat the cladding material of this gel rubber material fully.In certain embodiments, cladding material can be thermoplastic polyurethane (TPU) material.For example, pressure pad can be the gelling vessel that comprises the carbamic acid gels, and the carbamate gel coating has the film such as TPU film, silicone resin film or other thermoplastic films.According to an embodiment, gel rubber material can be surrounded by cladding material partly, makes the different piece of pressure pad interact with the moderator sheet in a different manner.For example, have only the surface that does not contact of pressure pad to be capped (for example, not contacting the TPU covering surfaces of moderator sheet), make the former gel rubber material of pad contact the moderator sheet with the moderator sheet.In this example, owing to the surface interaction between part and other material around that is capped of pressure pad, such as passing through minimize surface tension or frictional force, the part that is capped of pressure pad adheres to resistance on other material around.
The thickness of the pressure pad of the footwear insert that is used for being invented can change, and can be especially be the thickness of the integral thickness that is substantially equal to the footwear insert.In certain embodiments, pressure pad can have and equals about 10mm, equals about 8mm, equals about 6mm, equals about 5mm or equal the thickness of about 4mm.In a further embodiment, pressure pad can have about 1mm to about 10mm, approximately 1mm to about 8mm, approximately 1mm to about 6mm, approximately 1mm to about 5mm, approximately 2mm to about 5mm, or approximately 2mm to the thickness of about 4mm.
Footwear insert according to an embodiment of the invention can comprise a plurality of pressure pads.A plurality of pressure pads can comprise two, three, four, five, six, seven, eight, nine, ten, 13,14,15,16 or even more a plurality of pad.In certain embodiments, comprise that for footwear insert according to the present invention a series of pressure pads are useful especially.Such as in this article use, term " series " refer to the number that limits, relative to each other aligning, shape, partly aim at or size is arranged on a plurality of pads on the insert with respect to the anatomy of pin.In certain embodiments, a series of pressure pads can be limited two or more these factors of combination.
Become serial gel mat can represent the pad of relative to each other aiming at, make two or more pads be in the specific spatial placement.For example, first pad can relative to each other be aimed at second pad, making win pad by second fill up around.Certainly, the present invention also comprises additional embodiments, promptly fills up or the like around the 3rd of second pad.
According to above, clear and definite is that employed pressure pad can adopt the different shape such as square, ellipse, circle, rectangle, oblong or analogous shape.In addition, two or more pads can be shaped so that especially that pad can be with the spatial placement location that limits.For example, pad can be rectangle around its periphery, but can have opening portion (for example, elliptical openings).Second pad can be shaped and size is set in the opening portion that embeds first pad.Certainly, opening portion can have arbitrary shape and size with second pad that is embedded in the opening portion.Likewise, first pad can be configured as that to make its periphery be the shape except that rectangle.The shape of pad can with special relevant of its two-dimensional shapes (that is, length and width).In certain embodiments, the size (thickness or height) of the 3rd pad can be understood to be in spacer and have under the situation of flat relatively shape (that is, having relative homogeneous thickness) as described thickness in this article.In a further embodiment, pad can form and have the thickness (for example, hemispherical or conical pad) that on length of filling up or width, changes.
Pressure pad becomes to locate so that it is partly aimed at the anatomy of pin is particularly advantageous serially.A plurality of parts of pin possibly born increased pressure significantly.Likewise, various diseases and illness can make some zone of pin become fragile, the caused further injury of normal pressure that pin is born when perhaps more and more being easy to receive by walking, running or other activities.The pressure pad of the footwear insert of being invented can be positioned on the insert with the zone corresponding to these qualifications of pin.Particularly, pressure pad can be positioned to and be called one or more regional alignment of the pin at " the circular position of pin ", perhaps with just before toe corresponding to the regional alignment of the pin of metatarsal head.The normal shape of pin and normal walking or road-work make this zone of pin bear bigger pressure.And the footwear of wearing shoes improperly and having a narrower box toe can retrain walking process (that is, power from heel through circular portion and the normal delivery through toe).Through placing a series of pressure pads so that can alleviate or eliminate metatarsalgia especially with the circular portion substantial registration of pin.
Another high-pressure area of pin is the heel of pin.Especially, running can be applied to excessive pressure on the heel.Therefore, a series of pressure pads can be arranged on the footwear insert of being invented, to aim at basically with the bottom of the heel of pin.Likewise, big toe possibly be the anatomy part of bearing excessive pressure of pin.The pressure harmful to big toe possibly caused by the characteristic or the other reasons of the gait of wearing shoes, individual improperly.Big toe is common positions for callus, corn or by other situations that excessive pressure causes.Therefore, a series of pressure pads can be arranged on the footwear insert of being invented to aim at big toe.
The size of pressure pad can change with respect to the position of the anatomy part of pin and the overall dimensions of footwear insert with respect to position, the pad of other pads according to shape, the pad of pad.
Except that pressure pad, the footwear insert also comprises the pressure moderator sheet of shaping according to one embodiment of present invention.Like what more specifically describe in this article, pressure moderator sheet can provide so far as yet not by this area thinks useful unique and special function.Particularly, pressure moderator sheet can be positioned to make pressure pad to separate with user's pin.Therefore, the pressure between pin and the pressure pad can be distributed on the moderator sheet partly.
The pressure moderator sheet that is shaped can comprise providing like the useful any material of function of described buffer in this article.In certain embodiments, moderator can be partly the elastomeric material of distortion particularly, such as around pressure pad or at the pressure pad initial alignment but be out of shape in the zone that has been removed, as said.In certain embodiments, pressure moderator sheet can comprise a slice thermoplastic polyurethane (TPU).Can use durable thermoplastic arbitrarily, wherein transparent material has maximum Graphics Design potentiality.
Preferably, pressure moderator sheet has being badly deformed or " (bottoming out) touches the bottom and bounce back up " of zone that enough rigidity remove with the renitency pad.For example, if pressure pad has the average thickness of 2mm, when applying power on the separate areas that is not having pressure pad, if the pressure moderator sheet of overburden pressure pad is out of shape 2mm at least downwards, then pressure moderator sheet is considered to touch the bottom and bounce back up.Resistance to touching the bottom and bounce back up can be crossed over the distance that equals about 30mm, and this distance is measured with the open space between two adjacent pressure pads.In certain embodiments, this distance is measured with the open space between two adjacent pressure pads that except that pressure moderator sheet, do not have extra play or intermediate layer.In a further embodiment, can cross over the resistance that touches the bottom and bounce back up and equal about 25mm, equal about 22mm, equal about 20mm, equal about 18mm, equal about 16mm, equal about 15mm, equal about 12mm or equal the distance of about 10mm.In other embodiments, to the resistance that touches the bottom and bounce back up can cross over about 0.5mm to about 30mm, approximately 1mm to about 25mm, approximately 1mm to about 20mm, approximately 1mm to about 15mm or approximately 1mm to the distance of about 10mm.
In certain embodiments, the pressure moderator can be continuous sheet.In other words, according to embodiments of the invention, single footwear insert according to the present invention will comprise single pressure moderator sheet.In certain embodiments, single pressure moderator sheet also can be crossed over the whole length and the width of footwear insert basically.In other words, according to this embodiment, pressure moderator sheet can form the layer of the gamut existence of end cross section in the footwear that run through possible.In pressure moderator sheet, use continuous single can be particularly conducive to the pressure relaxation properties of guaranteeing this layer and can not trade off at any discontinuity point place on the pressure moderator sheet.A plurality of can combine perhaps can use the sheet of part as continuous sheet, although these replacement schemes can cause imbedding problem and make expensive more.
According to an embodiment, the moderator sheet can be a plurality of layers, and utilizes for example " double injection " moulding technology formation.About this respect; The crust of ground floor or moderator sheet (for example, the TPU material) can place grinding tool, and polymeric material (for example; Thermosetting or thermoplastic polyurethane) first injection can place on the crust, and mould is closed to solidify first injection and on crust, to form the ground floor polymeric material.Then, can be with moulds open, second injection of polymeric material (for example thermosetting or thermoplastic polyurethane) can place on crust and the ground floor polymeric material.Then, closing molding is to solidify second injection and to form second layer polymeric material.The ground floor and the second layer that are formed on the crust can have the material behavior that differs from one another, such as different rigidity and/or elasticity.For example, the ground floor that is formed on the crust can be harder than the second layer that is formed on the crust.
In certain embodiments, the pressure moderator sheet that is formed by solid material can be more useful.More specifically, be useful for avoiding the use of foamed material.Yet, do not hope to be fettered by theory, it is believed that the use of foamed material has reduced the ability of above-mentioned layer as real pressure moderator.Foamed material tends to resist being badly deformed of layer.When pressure was applied on the top surface of froth bed, in the time of possibly having the distortion of some discontinuous degree of depth that arrive froth bed simultaneously, the lower surface of froth bed not necessarily was out of shape (perhaps at least not being out of shape pro rata with the distortion of locating at the top of layer).Therefore, froth bed does not relax applied pressure on free space---more properly, and foam self absorption pressure.This does not provide the pressure of the type that realizes according to the present invention to relax.Except relaxing pressure, the moderator sheet is also with the canvas that acts on decoration, and this canvas can be realized and illustrated with seeing through in the inside of sheet, makes figure potential increase and more durable.As more fully describing hereinafter; Utilize relative thin, firm, continuous, flexure strip the favourable mitigation to institute's applied pressure to be provided as pressure moderator sheet; This pressure moderator sheet and pressure pad compound action are to provide comfortable and useful unique and useful stress reduction in treatment.
