Background technology

At GB-A-2,042, a kind of this type of pad case has been described in 868, wherein, in order to support footwear and outer bottom spare and in the flank district of footwear, pressure to be imposed on them, this pad case apparatus comprises a plurality of pads, and each pad is the plate-shaped member form, and each pad is configured to the surface portion that its marginal portion provides joint footwear.In addition, in order to support footwear and footwear outer bottom spare and in the front sole area of footwear pressure to be imposed on them, this device comprises a pad with surface portion of smooth substantially joint footwear.

In order to operate left shoe and right shoe, sole attaching press has two stations usually, each is used for the footwear of a pin, and each comprises a pad case and the mechanism that can engage with footwear in the front sole area of footwear and heel convex surface district, when putting on the footwear with convenient upper base pressure footwear is applied a buffer brake.And it still is that right shoe is come " customized " that each pad case is used to operate left shoe according to it.This process of being finished by footwear manufacturer usually customized comprises the surface portion of the joint footwear of the marginal portion that such shaping " flank " (Waist) is filled up, thereby adapting to left shoe or right shoe, is be shaped surface portions of " front sole pad " joint footwear (forepart) of left foot or right crus of diaphragm according to the footwear that will operate simultaneously.In case pad adapts to requirement by this way, operating personnel just can partly settle footwear according to shaped surface so.

Must provide a reason of the surface portion of shaping to be, front sole pad also has the flank pad, and both are normally made as solid rubber by hard relatively material, even therefore they also are not easy distortion and meet the sole shape under last bottom pressure, be out of shape still very little so that outer bottom spare meets the sole shape.On the other hand, thereby to be appreciated that enough pressure makes upper base spare symbol sole shape and outer bottom spare is bonded on the sole during bottom pressure in order guaranteeing to apply being applied with outside, in this pad or each are filled up, to need hardness to a certain degree.

Usually, as for example GB-A-2, explanation in 042,868, supporting arrangement comprises another pad simultaneously, is arranged near the flank pad and in heel direction one side of flank pad, and can engages with footwear in the palm Kou Xian district of footwear.This kind pad also provides a position, is used to be fixed on the joint of the heel palm mouth of the outer bottom spare on the sole.Under the static condition of bottom bonding machine, this " palm mouthful line " (breast line) pays somebody's debt and expect repayment later than flank pad and more projects upwards, so that with the footwear pad case of packing into, for this reason, can settle footwear along its length and make the orientation of footwear and the viewpoint of the shaped portion collimation of front sole pad and flank pad simultaneously thereby firmly make the heel palm mouth of outer bottom spare enter pad from operating personnel, a palm mouthful line pad is easier to be out of shape than a middle pad.But, be appreciated that a kind of like this device seriously depends on operating personnel and accurately settled footwear/outer bottom spare assembly before the operation bottom bonding machine.

One of various purposes of the present invention provide a kind of improved pad case, and this pad case does not require various pad customized and is convenient to accurately settle footwear, no matter it is left shoe or right shoe, needn't rely on operating personnel's skill fully.Disclosure of an invention

Therefore the present invention provides a pad case that comprises cushion device for the sole attaching press of footwear in one of aspect they are several, it comprises that at least one has the pad of the surface portion that engages footwear, be used to support the footwear that shoe tree is housed that the bottom is downward, the outer bottom spare of footwear is settled near sole, and be used to produce impressed pressure to compress this outer bottom spare facing to sole, utilize the adhesive that is applied between outer bottom spare contact surface and the sole contact surface that outer bottom spare is bonded on the sole thus, it is characterized in that, ground floor and the second layer that relatively can compress that backing is provided for ground floor that the hard relatively material of usefulness that above-mentioned at least one pad comprises provides the surface portion that engages footwear is made, outside being applied with during bottom pressure, ground floor is forced to produce distortion, thereby the outer bottom spare that makes footwear meets with the bottom shape of footwear in the zone that it engages with above-mentioned pad, and this second layer by compression and the distortion of adaptation ground floor.

Therefore be appreciated that, in the pad case, use the occasion of one or more this kind pads, the surface portion that no longer needs customized or its joint footwear that are shaped is to be fit to operated specific footwear or really to be fit to a selected left shoe or right shoe, but because its deformability, depend on style and size that pad can be fit to far-ranging footwear, and not pipe shoe be left foot or right crus of diaphragm.

In pad case of the present invention, as in the pad case of routine, in order to support footwear and sole spare and in the flank district of footwear pressure to be imposed on them, preferably cushion device comprises a plurality of pads, and each pad is the plate-shaped member form.In addition, preferably, each parts has two opposed edges parts, and the pad case provides the installed part of each pad usefulness of a supporting, and one of marginal portion that makes each pad optionally is in the position that engages with footwear.In a preferred embodiment, the ground floor of each parts comprises that a thickness that passes parts simultaneously extends to the centre bore of another side from it, holds the second layer in this hole.In addition, wherein each flank pad is made such shape, makes their two opposed edges partly be preferably different depth, thereby has different deformabilities.

Be appreciated that the flank pad that uses this kind configuration, can change the deformability of each pad according to the requirement of specific footwear.For example, under the situation of women's shoes, its sole will tend to have circular lateral contour, and preferably these pads can center on sole " parcel ", thereby make outer bottom spare meet sole profile, provide the marginal portion of the surface portion that engages footwear to be preferably the quite shallow degree of depth for this reason; And under the situation of Men's Shoes, it tends to have more flat lateral contour, therefore preferably uses to have the marginal portion of the bigger degree of depth, because do not require the effect of winding, thereby the deformability that requires is less.

As already mentioned, in the sole attaching press of routine, in order to support footwear and footwear outer bottom spare and in the front sole area of footwear pressure to be imposed on them, cushion device also comprises a front sole pad with smooth substantially surface portion.In addition, according to the present invention, this front sole pad is a multiple pressure pad preferably, and the surface portion of its joint footwear is made of and is formed to its flat surfaces part ground floor.Therefore, again, outside being applied with during bottom pressure, thereby this ground floor deforms and make footwear outer bottom spare meet the sole shape in its front sole area, second layer pressurized and adapt to the distortion of ground floor.Therefore, also be appreciated that in this case, do not need (hand) front sole pad customized, and front sole pad can be used for left shoe and right shoe now and needn't retrofit specific " about only " of footwear.

Flank pad and front sole pad can be made with any suitable material, and as rubber, preferably ground floor has the about 60 ° hardness of Shore A and the second layer has the about 40 ° hardness of Shore A.

In pad case according to the present invention,, preferably provide another palm mouthful line pad as in the pad case of routine.Secondly, in the present invention, above-mentioned another pad preferably includes support plate and block made from compressible material of a rigidity, this block has trapezoidal substantially level cross-sectionn, and a face that can engage by the heel palm of the footwear of cushion device supporting mouthful is provided, this face along lateral inclination so that the skew of the longitudinal centre line of heel end adapts to the longitudinal centre line of its front sole area.Be appreciated that use a such palm mouthful line pad, the present effect of this inclined surface be with footwear/outer bottom spare component placement in desired longitudinal direction, and needn't rely on operating personnel's skill.In addition, because no longer need assign to settle footwear now with respect to any forming section on the surface of the joint footwear of flank pad, so can use rational tolerance in the time of in footwear being placed in the pad case, the deformability of flank pad guarantees that applying enough pressure makes outer bottom spare meet sole profile.

In addition, in a preferred embodiment, for a palm mouthful line pad provides an installed part, the latter can optionally be contained in one of two positions this pad, and the inclination of its opposite face can be that left shoe or right shoe are selected according to footwear thus.Therefore be appreciated that, can consider a kind of sole attaching press now with footwear of an independent station, wherein use same pad case and just can operate left foot and two kinds of footwear of right crus of diaphragm with some pads, because front sole pad and flank pad are no longer customized to left shoe or right shoe, a palm mouthful line pad can reverse in addition.

For the ease of settle the heel palm tight-lipped by the palm mouthful line pad the surface and do not apply unsuitable pressure pad be out of shape, as the way of conventional sole attaching press, preferably the marginal portion in abutting connection with the palm mouth line pad of inclined surface has rounded corners.This rounded corners is the compromise that adapts to the heel palm mouthful profile variations in essence, but in addition, in the machine as an above-mentioned independent station, a plurality of palms mouthful line pad can have the rounded corners of different radii to adapt to the style of different footwear.

The palm mouth line pad of making definite shape as mentioned above also can be used in the double sole attaching press certainly.Under such a case, preferably the palm mouth line spacer of each supporting arrangement has the rounded corners that each marginal portion along it in abutting connection with its inclined plane forms, radius is a different value, a palm mouthful line pad can exchange between two stations, can be that left shoe still is that right shoe comes to select correct inclination and radius of corner for each station thus according to the footwear of operation.

Others in several aspect of the present invention will be stated in the claim 10 of appendix.

Describe the pad case of a kind of sole attaching press and its part of formation with reference to the accompanying drawings in detail, this sole attaching press and pad case illustration sole attaching press of the present invention and pad case aspect.It will of course be appreciated that and select this sole attaching press and this pad case the present invention to be described as just non-limitative example.

Brief description of drawings

In the accompanying drawing:

Fig. 1 is the side view that cuts open according to the part of pad case of the present invention, represents details and the half sole jack and the heel end jack of its front sole pad, and both form the buffer brake applying mechanism of sole attaching press the back, and the pad case is formed the part of this sole attaching press;

Fig. 2 is the cross-sectional view of flank pad that forms the part of pad case shown in Figure 1;

Fig. 3 and 4 is respectively the plane and the side view of the palm mouth line pad of above-mentioned pad case.

Implement preferred plan of the present invention

The sole attaching press of the present invention of explanation comprises the pad case that a total usefulness 10 is represented now, pad case itself comprises that thereby one is installed in the supporting member 14 around axle 16 and makes the so-called front sole pad 12 that pivot type rotation adapts to the angle of sole in its front sole area, a plurality of flank pad that engages with outer bottom spare/sole assembly 18, the palm mouthful line pad 20, a heel supporting member 22 and a heel near filling up 24 in sole flank district, also will reference to their back.

The front sole pad 12 of pad case 10 has an initial position or the resting position around axle 16 determined by adjustable latch 26.And, when sole attaching press uses, usually will fill up case and be locked on the position according to the angle of sole, for example as GB-A-2, detailed description in 042,868.

The flank pad 18 that is arranged between the front sole pad 12 and the palm mouthful line pad 20 is quite narrow, thereby they can meet last elasticity requirement, the heel height that promptly adapts to footwear, each flank spacer has its corresponding piston-cylinder unit 28, makes the flank pad individually to move.As shown in fig. 1, even when sole attaching press is in resting position, the palm mouthful line pad 20 also is in the state higher than flank pad 18, and being used for the position of definite by this way loading duration pad case along the length direction of footwear, configuration state makes the heel direction engage sides of heel palm mouth and the palm mouthful line pad 20 or heel slap oral region and slap mouthful heel direction engage sides of line pad 20.

Heel supporting member 22 be mounted to the effect lower edge of piston-cylinder unit 30 short transverse move and with the heel engaged at end and the disengagement of outer bottom spare/shoe assembly; This supporting member usually is used for the Men's Shoes situation, and wherein heel is low also has bigger area really, so this assembly is applied a clamping force that makes progress.On the other hand, heel is used for women's shoes or high-heeled shoes near pad 24, and its shape can apply the pressure component of length direction and short transverse to footwear.Heel is installed on the balladeur train 32 near pad, and balladeur train 32 carrier bands are on pillar 34, and pillar 34 is mounted to around the axle 36 of pad case and makes pivot type rotation.And when heel supporting member 22 raise under the effect of piston-cylinder unit 30, pillar 34 was made pivot type rotation by pin- groove connector 38,40 with heel supporting member 22.(when not needing heel near pad 24 the time, pin 38 can withdraw from, and pillar swings to subsequently by on the resting position of determining near part 42.Simultaneously, mat (not shown) is positioned on the heel supporting member 22 and provides a surface that engages footwear for supporting member; On the other hand, when using heel near pad 24, above-mentioned mat is removed from supporting member 22, makes that above-mentioned mat can not hinder footwear when supporting member raises).This device also can be at GB-A-2, obtains more detailed description in 042,868.

Sole attaching press also comprises a half sole jack 50 and a heel end jack 52.Heel end jack 52 is arranged on the position relative with slapping mouthful line pad 20, makes to be in the heel palm oral region of assembly to outer bottom spare/shoe assembly applied pressure by heel end jack.Jack 52 is pushed down heel pad 56 by pin-groove connector 54, and heel pad 56 engages the convex surface of the shoe tree L of the footwear that shoe tree is housed.By arranging ground, heel pad 56 as close as possible shoe tree lands to engage the convex surface of shoe tree, can alleviate owing to make any tendency of footwear hypsokinesis to the shoe assembly applied pressure by heel end jack.

Half sole jack 50 is pushed down front sole pad 60, the latter or the bottom in the vamp district of contiguous footwear engage with footwear.The elastomeric material that front sole pad 60 usefulness can be out of shape is made, and this material has the Xiao A hardness of 20 to 55 scopes; Therefore, front sole pad 60 is pushed down when engaging easily deformable and thus applied pressure is diffused on sizable area when itself and the front sole area of footwear.Preferably the size of front sole pad 60 should be done like this, makes that when it so was out of shape, it only contacted with footwear, particularly should not contact with the front sole pad 12 of pad case 10, because this can offset added pressure.

Front sole pad 60 is the bomb shape, avoids the contact (no matter added amount of pressure) between deformable pad and the front sole pad 12 for guaranteeing to spread institute's plus-pressure well, and this is counted as optimum shape.Shape is generally taper in this case, apicad sharply comes to a point.

The deformable pad of half sole jack also can use other shape, illustrates among the common pending application application No.GB95/00063 that proposes as us.

As can be as seen from Figure 2, each flank pad 18 be plate-shaped members 72 that are roughly rectangle, but has the bight of rounding.The upper rim of the pad 18 shown in Fig. 2 forms the first surface part 18a of flat (or flat substantially) joint footwear, and lower limb forms the second portion 18b of flat (or flat substantially) joint footwear.Secondly, in order to support each pad 18, carrier 70 that becomes definite shape of its relevant piston-cylinder unit 28 supportings wherein can support pads 18, selects one of above-mentioned surface portion 18a, 18b to be in operating position.

Observe Fig. 2, plate-shaped member 18 comprises the ground floor 72 that a solid hard relatively elastomeric material (having the about 60 ° hardness of Shore A usually) is made, the latter has a centre bore, settle second block or the layer 74 of a backing in the hole, it passes the thickness of plate-shaped member 72, simultaneously extends to another side from it.And the second layer 74 also is to make with elastomeric material, but this material relatively can compress in this case, and hardness is about 40 ° of Shore A.This second layer is used to adapt to the distortion of ground floor.

Depth ratio second this kind surface portion 18h and the distance between the centre bore that it is further noted that the first surface part 18a that engages footwear and the ground floor between the centre bore from Fig. 2 are much bigger.Therefore, though the material of ground floor 72 is hard inherently, its zone that forms second surface part 18b is tended to partly be easier to distortion than near the parts the first surface 18a.

In use, when any surface of pad pressurized and when pressing to sole under the bottom pressure outside last, the surface portion (18a or 18b) of the joint footwear that form by ground floor 72 under impressed pressure with easily deformable, thereby make pad promote the shape that footwear outer bottom spare U meets sole in the sole flank district, and second layer pressurized correspondingly.

Forward Fig. 1 to, can see that front sole pad 12 also has sandwich construction, comprise a ground floor 76 that forms upper surface portion smooth or the joint outer bottom that cardinal principle is smooth, this ground floor is hard relatively elastomeric material, be generally 60 ° of Xiao A hardness, and to be subjected to the backing of a second layer 78, the latter be relatively can the compressed elastomer material, has the hardness of 40 ° of Shore A usually.And if desired, this multi-layer configuration can comprise an interlayer, the above-mentioned two-layer supporting that turns over and be subjected to another layer material (not shown), and this another layer material has the hardness similar to ground floor.

Can also from Fig. 1, see, the palm mouthful line pad 20 by make the heel palm mouthful line and pad 20 to the engaging of end face of heel and along pad case direction arrangement footwear.The particular configuration of this pad can more clearly be seen from Fig. 3 and 4.With reference to these two figure, pad 20 comprises a metal substrate 80 along the horizontal expansion of sole, and a bonding pad 82 that becomes definite shape on it, pad 82 have one to provide along the surface 84 of the joint heel palm mouthful line of lateral inclination.The angle that faces toward between substrate 80 and the inclined surface 84 is preferably about 8 °.Have been found that such angle can adapt to the style of most conventional footwear, wherein the longitudinal centre line of heel end can be to similar angle of longitudinal centre line skew of the half sole of footwear.Like this, by settle footwear suitable " anyway " (left side or only right just, as situation may be) heel slap tight-lipped abutment surface 84, the half sole of footwear S can correctly be settled with respect to front sole pad 12 and flank pad 18, just makes the longitudinal centre line of half sole and the longitudinal centre line collimation of pad case itself usually.

As can being more clearly visible from Fig. 4, top edge 82a provides one to engage the first surface part of footwear and lower limb 82b provides such second surface part.By provide one can be along either direction, make just that any is positioned at the top among its surface portion 82a, the 82b, adapt to the installing rack 86 (Fig. 1) of the palm mouthful line pad 20, can dispose inclined surface 84 according to this orientation selectivity ground and be used for left footwear or right footwear.

Can see from Fig. 4 that also the terminal of each surface portion 82a, 86b is fillet part 82X, the 82Y in abutting connection with inclined surface 84.In an embodiment (not shown) that is applicable to single station sole attaching press, radius 82X, 82Y are identical value, make this pad only need reverses direction just optionally to be used for left footwear and right footwear.But in another kind of embodiment (as shown in Figure 4), wherein this pad is intended for more habitual double sole attaching press, more particularly, one of them station is used to operate left footwear and another station is used to operate right footwear, the radius of corner at this place, pad top is different from the place, bottom, such as top radius of corner 82X is about 12mm, and the radius of corner 82Y of bottom surface section is about 19mm.

Be appreciated that a kind of like this configuration of utilization, this pad has generation to the simple reorientation of left footwear and right footwear the top edge of different radii in a pad case.On the other hand, if intercourse now two the pad casees pad 20 and reverse its orientation, so optionally can make both or all present less radius of corner, perhaps all present bigger radius of corner.

Certainly should be appreciated that in each case the purpose of radius of corner is to allow to fill up in the angle that enters between heel palm mouth and the outer bottom spare lower surface, thereby in the operation of sole attaching press sufficient loading pressure is added in this zone.

Have been found that use according to sole attaching press of the present invention, need not any pad customized, use same pad configuration just can easily adapt to the footwear of all styles of and size, also can adapt to the footwear of left foot and the footwear of right crus of diaphragm.
