Description

The holding device of foot or footwear

Technical field

[01] the present invention relates to foot or footwear are remained on holding device on the sports apparatus, to this holding device, the maintenance of foot or footwear is undertaken by at least one root system band.

Background technology

[02] this device be used to avenge or skis on surfing exercise, skiing or water skiing exercise, the exercise of snow upper slide or skidding exercise etc.

[03] device that has frenulum of prior art generally comprises a side (lat é rale) part and a centre (m é diale) part, form a zone of accepting foot or footwear between two parts, also comprise at least one frenulum, frenulum is connected with each part of mid portion with the side part with an intermediate connector by a side connector.Each frenulum is used for foot or footwear are remained on region of acceptance.

[04] side connector and intermediate connector lay respectively on side part and the mid portion, and when remaining on sufficient and footwear in this device, side connector and intermediate connector are positioned at vola place and sole place substantially.Therefore, frenulum cover foot or footwear the side and above.There is certain transverse curvature free degree the be provided with side and the centre that are beneficial to footwear of side connector and intermediate connector.

[05] for example to skis, this free degree helps laterally moving of body wt.Therefore the user can the end of adjustment devices between or the contact force between plank and the ground.The user removes the weight of health towards an end, a gravity higher than end opposite is born in this end.This phenomenon helps to change the path of plank.

[06] still, the weight of moving is not unique effective action of control instrument.In fact, the momentum transmission between user and the apparatus also is useful to control instrument.Momentum transmits by frenulum, has proposed to make frenulum to have certain structure, so that make frenulum more solid.

[07] for example, be provided with the frenulum that has rigid element according to 2 838 978, holding device of patent application FR.When these parts combined, frenulum formed a rigidity girth member around foot and footwear.It is fine to observe the transmission efficiency of handling momentum on this device.As if but the horizontal free degree of footwear is poor.So weight that is not easy laterally to move.

[08] in other words, aspect the momentum transmission, obtain advantage, and aspect body wt horizontal mobile, lose ground.

Summary of the invention

[09] one of purpose of the present invention is exactly to improve holding device.Particularly the present invention should can make body wt laterally move on a device that is provided with at least one frenulum, aspect the transmission of handling momentum good efficient is being arranged simultaneously.

[10] for this reason, the present invention proposes a kind of a foot or footwear to be remained on a device on the sports apparatus, this device comprises a side part and a mid portion, two parts form a zone of accepting foot or footwear, also comprise at least one frenulum, this frenulum is connected with each part of mid portion with the side part with an intermediate connector by a side connector.

[11] holding device according to the invention is characterised in that, the side connector of frenulum and intermediate connector are asymmetric on height of devices.

[12] therefore, one of them in side connector and the intermediate connector is distant from apparatus, and another is closer from apparatus.Therefore one of them of the side of device part and mid portion surrounded foot or footwear on a higher height.Because this height, a bigger part of foot or footwear is relative with one of device harder part.Therefore the user is with the momentum of good efficient transmission manipulation.

[13] on the other hand, frenulum keeps a sufficient length in the face of foot and footwear, so that operate in transverse curvature on enough amplitude.This length of frenulum can be wrapped up foot or footwear well from minimum connector.This parcel helps foot or footwear to be attached on the top edge.

[14] therefore device according to the invention has the advantage of coordinating two specific characters: being to transmit to handle momentum on the one hand, is the free degree of transverse curvature on the other hand.Consequently realize the manipulation of apparatus better.

[15] in some cases, side partly has a side lower surface, lower surface in the middle of mid portion has, and the side lower surface is used for being connected with sports apparatus with middle lower surface.

[16] therefore, the side connector is different with the distance between intermediate connector and the middle lower surface with distance between the side lower surface.

[17] this is that the position of a kind of side connector that obtains frenulum and intermediate connector is in highly asymmetric a kind of mode.

Description of drawings

[18] can understand other features and advantages of the present invention better by following description and with reference to accompanying drawing, accompanying drawing represents how to realize the present invention according to some non-limiting examples, wherein:

[19] Fig. 1 is a perspective view that meets the holding device of first embodiment of the invention, and frenulum is closed among the figure;

[20] Fig. 2 is a profile along the II-II line of Fig. 1;

[21] Fig. 3 is one and similarly schemes with Fig. 2, and frenulum is open;

[22] Fig. 4 is one and meets similarly scheming with Fig. 2 of second embodiment of the invention;

[23] Fig. 5 and Fig. 4 are similar, and frenulum is open.

The specific embodiment

[24], it should be understood that they also are used for above-mentioned others although the embodiment that describes below more relates to the skis aspect.

[25] first embodiment are shown in Fig. 1-3.

[26] as what see among Fig. 1, a holding device can remain on footwear that do not show on the plank 2 temporarily.

What [27] known is, holding device 1 comprises the base 3 of a longitudinal extension between a rear end 4 and front end 5.

[28] base 3 has a upper surface 6 and a lower surface 7, and upper surface 6 is used to be positioned at sole one side, and lower surface 7 is used to be positioned at plank one side.

[29] base 3 remains on the plank 2 by a disc-shaped part 10, and disc-shaped part 10 itself remains on the plank 2 by screw 11.

[30] certain, the parts that other keeps base 3 also can be set.

[31] transverse edge of base 3 is a side part 12 and a mid portion 13, and these two parts form a zone 14 of accepting footwear.Side part 12 has a side lower surface 15 that is used in plank 2 one sides, similarly, lower surface 16 in the middle of mid portion 13 has, it also is used in plank one side.

[32], for example see that the side lower surface 15 of

part

12,13 and each in the middle lower surface 16 all make the lower surface 7 of base 3 prolong at Fig. 2 according to the first embodiment of the present invention.So continuous lower surface 17 of three

lower surface

15,16,7 formation devices 1.In this case, this surface 17 is the plane substantially, but it can not be the plane also, and has a projection.

[33] lower surface 17 directly contacts with plank 2.Therefore, the

lower surface

15,16 of the lower surface 7 of base 3 and side part 12 and mid portion 13 directly contacts plank 2.But also can consider these

surface

7,15,16 mediate contact planks,, or not pass through buffer board for example by a buffer board.

[34] according to the first embodiment of the present invention, the shape of side part 12 and mid portion 13 is respectively a side side plate 12 and a middle side plate 13.When footwear were in place on device 1,

side plate

12,13 side direction were along sole.Certainly, also can consider

side plate

12,13 other setting in addition, so that form side part and mid portion.For example simple side and intermediate barrier may also be fit to.

[35] side part 12 and mid portion 13 are rigidity, and promptly they are indeformable substantially under the effect of steering force.Therefore the user can provide and handle momentum or accept sensory information.

[36] as seeing among Fig. 1,4 places connect

side plate

12,13 in the rear end by an arch 20.Base 3,

side plate

12,13 and arch 20 are preferably formed as a monolithic part of for example being made by synthetic material.But can consider that also side plate or arch are some parts that link together by any way, as bonding, welding, screwing, inlay etc.

[37] can consider that also device 1 does not comprise arch, perhaps

part

12,13 is directly stretched out from plank.

What [38] need to replenish is, support part 21 makes the user carry out back support with shank after one.Back support part 21 for example connects together by a hinge 22 and

side plate

12,13.

[39] two frenulums also can be set,, remain in the region of acceptance 14 between the

side plate

12,13 so that removably footwear are remained on the base 3.

[40] first frenulum 23 is positioned at the rear portion, locates on the instep when foot is held.Second frenulum 24 is positioned at the front portion, when foot when being held at the vola place.

[41] each frenulum 23,24 extends laterally between the

side plate

12,13.

[42] certain, the different frenulum of quantity also can be set.

[43] owing to reason easily, only describe first frenulum below in detail.

[44] according to the first embodiment of the present invention, as what see among Fig. 2,3, for example first frenulum 23 comprises a side part 25 and a mid portion 26.

[45] the side part 25 of frenulum 23 is connected with side part or side plate 12 by one first side connector 30.Similarly, the mid portion 26 of frenulum 23 is connected with mid portion or middle side plate 13 by one first intermediate connector 31.

[46] to be respectively an axis be 32 and 33 hinge to the shape of side connector 30 and intermediate connector 31.Each

hinge

30 and 31 can comprise a component part, as a rivet, screw, nut, pad, gudgeon etc.

[47] certain, also can form

connector

30,31 with other structure, as one center on a bar (passant) curl up body (enroulement).

[48]

axle

32,33 of

hinge

30,31 is laterally substantially, and substantially parallel with base 3.This makes frenulum 23 can cover footwear better.

[49] for example, the side part 25 of first frenulum 23 comprises a tooth bar 34.Mid portion 26 comprises the locking device 35 of a band ratchet.The locking device 35 of tooth bar 34 and band ratchet forms a jockey, and this jockey makes side part 25 and mid portion 26 be connected to each other in reversible mode.Also can as shown in Figure 2, perhaps open frenulum 23, as shown in Figure 3 according to the elasticity locking footwear of hope.

[50] can certainly consider to replace the combination of tooth bar and pawl device with other any jockey.

[51] in a word, for the application of skis aspect, promptly the direction from a side plate to another side plate is not extending substantially at their length direction for frenulum 23,24.Therefore need to select to constitute the material of frenulum.For example can be polymer and reinforcing or unreinforced polyurethane.

[52] but each

part

25,26 of frenulum 23,24 can more or less be soft.Its curve is variable, and can fold, so that adapt to foot or footwear.

[53] according to the type of using, frenulum 23,24 can comprise much soft material, so that adapt to foot and footwear better.

[54] according to the present invention, different apart between d1 and first intermediate connector 31 and the middle lower surface 16 between side connector 30 and the side lower surface 15 apart from d2.

[55] therefore, in side connector 30 and the intermediate connector 31 is distant from plank 2, and another is closer.Therefore install 1 side part 12 and mid portion 13 and on a bigger height, surround footwear.Because this height, the bigger part of footwear is supported on the harder part of device 1, and this part is one of them of

side plate

12,13 in this case.Therefore the user transmits operation information with good efficient.

[56] on the other hand, frenulum 23 keeps a sufficient length relative with footwear, so as can be on enough amplitude transverse curvature.

[57] device 1 according to the invention can transmit the manipulation momentum on the one hand, and the free degree of transverse curvature can be arranged on the other hand, therefore realizes the manipulation of plank better.

[58] according to first embodiment, and with reference to Fig. 2,3, between side connector 30 and the side lower surface 15 apart from d1 less than between intermediate connector 31 and the middle lower surface 16 apart from d2.Because less than distance d2, side connector 30 is than intermediate connector 31 more close lower surfaces 17 apart from d1.In other words, the side axle 32 of side direction hinge 30 is than the jackshaft 33 more close lower surfaces 17 of middle hinge 31.Consequently, device 1 connects together with plank 2, and side connector 30 is than intermediate connector 31 more close planks 2.

[59] this set can be supported on the rigid element of device 1 centre of footwear according to a height bigger than side.This part is mid portion 13 in this case.In fact, frenulum 23 wraps up the side of footwear fully, and makes the footwear rigid element 13 that reclines.

[60] therefore control middle momentum better, this control is relevant to the possibility that side moves with the weight of health.

[61] certain, the weight of health also can move to the centre.

[62] carrying out momentum control from side also can be better.Intermediate connector 31 positions are higher reduces frenulum laterally deforming to device 1.In fact, when the user when side moves his weight, a bigger part of frenulum 23 is subjected to tensile stress.Therefore the support of user's side is more accurate.

[63] thus the difference in height of frenulum connector can control side and middle momentum better.

[64] as what recognize by the Fig. 4,5 that represents the second embodiment of the present invention, opposite setting also is possible.

[65], only use and understand necessary reference number owing to reason easily.

[66] holding device 51 comprises a base 52, and base 52 has a upper surface 53 and a lower surface 54.The transverse edge of base 52 is side part or side plate 55 and mid portion or side plate 56.Side part 55 and mid portion 56 form a region of acceptance 57.

[67] side part 55 and mid portion 56 have a side lower surface 58 and a middle lower surface 59 respectively.Each of the

lower surface

58,59 of side part 55 and mid portion 56 prolongs the lower surface 54 of base 52.Therefore, a continuous lower surface 60 of three

lower surface

58,59,54 formation devices 51.

[68] being provided with one first frenulum, 65, the first frenulums 65 is connected to each other side part 55 and mid portion 56 by one first side connector 66 and one first intermediate connector 67.For

example connector

66,67 is by being that the hinge of axis is realized with side axle 68 and jackshaft 69 respectively.

[69] according to second embodiment, between side connector 66 and the side lower surface 58 apart from d3 greater than between intermediate connector 67 and the middle lower surface 59 apart from d4.Because greater than distance d4, side connector 66 is more farther than intermediate connector 67 apart from lower surface 60 apart from d3.In other words, the side axle 68 of side hinge 66 is more farther than the jackshaft 69 of middle hinge 67 apart from lower surface 60.Consequently, device 51 connects together with plank, and side connector 66 is more farther than the intermediate connector 67 that is connected with plank apart from plank.

[70] this set can make the rigid element of the side of footwear according to a height contact device 51 bigger than the centre.Rigid element is a side part 55 in this case.Therefore can control the momentum of side better, this control is mixed and is moved to the centre in the weight that can make health.

[71] certain, body wt also can move to side.

[72] in a word, the technology of material of knowing by industry technical staff and use realizes the present invention.

[73] certain, the invention is not restricted to above-described embodiment, but comprise all equivalence techniqueses that can enter in the following claim scope.

[74] particularly, to an independent frenulum, perhaps part frenulum perhaps to all frenulums of a device, can consider to make the side connector different with the distance between intermediate connector and the middle lower surface with distance between the side lower surface.

[75] distance between the lower surface of a connector that frenulum is minimum and a part can be between lower surface 7 and frenulum 23 peak when closing distance zero to 50 percent.

Distance between the highest connector of [76] frenulums and the lower surface of a part be between lower surface 7 and frenulum 23 peak when closing distance 85 1 15 to percent.

[77] can consider that also device does not comprise base, and side part and mid portion are fixed on the plank directly.

[78] can consider interior, the

side part

12,13 of Any shape.For example the shape of a part may be substantially of the shape of footwear.In this case, this part to small part has aduncate shape, and perhaps part is straight, and part is interior curved.
