Description

In-line roller skate

Relate generally to of the present invention keeps and supports the in-line roller skate of skater's pin regularly, more particularly, relates to and has the in-line roller skate of special boots structure with the rigid material that reduce to surround skater foot.

In-line roller skate generally comprises the upper of a shoe that all is contained on the framework, the interior end and bottom, and framework is supporting one by one in upright arrangement install, a plurality of rollers that rotate in the rotational plane of a common longitudinal extension.The shape of upper of a shoe can comprise band, clamp belt and/or other fixture, flap and/or toe cap around the foot and the ankle that cooperate the wearer, and all these provides the supporting to skater foot.Being provided with the rigid lower portion structure that is used to support upper of a shoe and in-line roller skate roller up to the roller skating boots is underframe.

For making in-line roller skate obtain optimum performance, in-line roller skate is remained on the vertical substantially position.In this respect, the main effect of the upper of a shoe of in-line roller skate provides supporting role and comfortableness; Comfortableness in upper of a shoe is irrelevant with high degree of support usually.In other words, the rigid supporting structure in upper of a shoe increases rigidity and volume easily, considers the temperature climate environment that helps roller skating in upright arrangement, and this also makes ice skating boot heaviness, sultry and uncomfortable easily.If too much consider comfortableness rather than supporting, can cause serious ankle or other wound so, thereby in the past, it is main design standard that suitable supporting is provided always in the upper of a shoe of in-line roller skate.

Upper of a shoe usually is to be made of molded plastic casing, and this housing comprises the bottom, and plastic casing is rigidity normally, air-locked material.The plastic material of housing generally constitutes the external structure of upper of a shoe, wearer's ankle is provided the supporting of necessity.In addition,, thereby in plastic casing, generally be provided with the soft liner of latex sponge independently or other material, so that provide comfortableness slightly for the wearer because plastic casing is rigidity.Therefore, comfortable for foot, enough liner effects are provided, in said structure, it is very important that liner becomes.Owing to above-mentioned soft material, add the plastic casing of rigidity, constitute good heat guard, be difficult for transmitting heat or taking away air, thereby form a kind of sultry upper of a shoe from wearer foot.

For lateral stability is provided, common alpine skiing boots structure often is applicable to in-line roller skate.This boots can provide necessary supporting of in-line roller skate and durability characteristics.United States Patent (USP) the 4th, 351, No. 537 and the 5th, 171, No. 033 all is to be applicable to the example of winter sports as the boots of the rigidity injection mo(u)lding of skating and alpine skiing, these boots can be retrofited to be used for roller skating in upright arrangement.Although the structure of this boots is suitable for the motion of cold climate very much, when motion that is used for temperature climate such as roller skating in upright arrangement, upper of a shoe is sultry and uncomfortable easily.

In addition because alpine skiing boots structure big unyielding the allowing of rigidity often, thereby this structure often to be unsuitable for some flexible be favourable roller skating in upright arrangement.In this respect, often to increase other liner so that improve comfortableness to the liner of in-line roller skate, and make a kind of stiff case can be suitable for different pin.But because this can completely cut off the sensation of wearer to skating and skating surface, thereby other liner can reduce the control of skater to ice skating boot.In addition, owing to increased other liner, skater's heel is upper and lower floating in upper of a shoe easily, make control because skater's pin in boots motion and weaken.

United States Patent (USP) the 5th, 171, No. 033 proposition can circulate around skater's foot by " clog-free at all passage " air is set in the synthetic shell of the rigidity of upper of a shoe, thereby eliminate some heats relevant with hard plastic shell.Though this patent seeks to solve comfortableness problem, disclosed upper of a shoe still is made of two parts, comprises hard plastic shell and soft liner.Under the temperature climate condition, because excessive heat savings and sweat accumulation, it is uncomfortable that this boots are compared with running shoes with common walking shoes.Consequently, skater's foot is usually hot, wet and uncomfortable.

Another problem that the skiing type boots of injection mo(u)lding is changed over in-line roller skate is, though for side direction ankle supporting provides fabulous lateral rigidity and rigid, this boots have also produced unnecessary and rigid and rigidity unwanted fore-and-aft direction.Skiing type boots so impair the performance characteristics of ice skating boot, therefore, also impair the ability that the skater utilizes its whole strength and flexibility because limited the range of movement of skater's leg and pin.For example, the high boots that the racer would rather be lower, they are light, softness can provide the supporting of side direction ankle again.Present available boots are perhaps too high, and are too hard on all directions, move towards perhaps that another is extreme, too soft on side direction.

In addition, the upper of a shoe up to the roller skating boots needs in light weight.When sliding on flat surface, roller skating person in upright arrangement must mention boots to form power forward in each step.Be suitable for the skiing boots of occasion, (because the slider relies on gravity to produce forward or downward motion) needn't lift along with each action of pin and fall boots, and be just heavy and huge when using instead to in-line roller skate.Heavy upper of a shoe can cause tired and reduce the recreational of skating.

People have proposed to provide comfortableness and the alternate manner that enough supports for roller skating in upright arrangement.Specifically, United States Patent (USP) the 3rd, 963,252; 4,418,929; And 5,069, No. 462 represented the roller skates framework, and it comprises a platform, makes the skater can wear city shoe and insert in a series of tie rods and supporting member that are generally metal structure.This ice skating boot provides another kind of footwear and frame structure for the rigid plastic enclosure and the liner of common in-line roller skate.But the serious problems of this structure are that the adjustable tie rod and the supporting member of this structure need adapt to multiple footwear sizes and shape, and volume is big and uncomfortable.In addition, the footwear type that this ice skating boot adapts to is limited in scope, and therefore, has another kind of requirement, that is, for suitably using ice skating boot, the skater will have suitable footwear type.

Because roller skating in upright arrangement can produce the speed that surpasses common skating, so also need speed control system on in-line roller skate.The front or rear portion that the existing scheme of speed control is included at least one the ice skating boot is provided with buffer or friction pad, makes the skater can tilt or mention his or his pin, forward or backward, makes that buffer and skating are surperficial to be contacted.Therefore, the skater drags buffer, is reduced to the speed that needs until him or she.Though this system is gratifying for the roller that uses in pairs structure side by side as the paired roller skates of support base.But narrow support base makes this braking maneuver be difficult to carry out on the in-line roller skate side direction.Higher speed makes the skater be difficult to mention or remove weight so that suitably make buffer location from a pin, thereby contacts with the skating surface.

United States Patent (USP) the 5th, 067, No. 736 a kind of common brakes that are used for roller skating in upright arrangement of expression.Fix a pad in arrester shell, shell is fixed on the in-line roller skate lower frame part.Other patents, specifically, United States Patent (USP) the 5th, 052,701 and 5,028, No. 058, similar brake pad is disclosed, they have the different structure that is installed in the in-line roller skate rear portion.But in all above-mentioned designs, the skater must transfer and promptly make its at least one pin location once more, so that suitably brake.

Proposed some braking methods that substitute, wherein, friction plate or pad have been acted on the wheel of in-line roller skate.United States Patent (USP) the 5th, 171 proposes a kind of braking method that flatly makes on the wheel that one or more plates are pressed against in-line roller skate for No. 032.This plate is driven by hand-control device 80, makes brake pad 40 essentially horizontally shift to the wheel 98 of in-line roller skate.

The brake apparatus that uses on the in-line roller skate, its structure must reduce to greatest extent because the possibility of the damage of the brakes that the object that the user falls or boots are contacted fixes causes.Its structure must further be avoided mincing and fill in brake, makes brake failure, thereby can not control skater's speed.The more important thing is that the structure of brake must avoid clogging nocuously roller when sliding.Therefore, importantly make brake apparatus location in the lower frame of in-line roller skate part, so as to prevent the movable part of brake be subjected to chips affect or since impact damage.

Another problem of ice skating boot existing structure in upright arrangement is that needs can be fast and changed roller easily when rolling wheel wear.Most of existing systems need carry out bigger dismounting in order to change roller, shed lower frame part or roller and remove the installation shaft structure.Aspect this, need to find a kind of method of easily changing or exchanging roller in upright arrangement for a long time always.

The development of boots of the present invention and liner is in order to overcome intrinsic defective and limitation in the existing ice skating boot.Boots of the present invention have increased supporting and comfortableness, because its structure and the soft of upper of a shoe and the interaction of various supporting structures, thereby control preferably is provided.

Have a comfortable softness, pliable and tough, ventilative footwear portion according to in-line roller skate disclosed in this invention, it comprises a bottom and an ankle support.Footwear portion can pack into for the overall situation consider and the rigidity that is provided with and semirigid structure so that the supporting required to skater foot to be provided.Structure can comprise one with soft, pliable and tough, breathable shoes portion for whole or be installed in the bottom and go up the heel that links to each other with the upper shoe part of softness.In preferred embodiment of the present invention, also comprise the ankle support that is articulated in interior or outer heel.In footwear portion, particularly also can be provided with the support of heel, arch of foot and thenar in the bottom so that improve the supporting and the comfortableness of in-line roller skate.

The ankle support be connected in adjustablely heel with provide ankle with respect to bottom side to vertical adjusting.The bottom can be provided with and be used for the device that partly is connected with lower frame, substantially a plurality of rollers is rotatably supported in the common rotational plane.The jockey of bottom on the lower frame part can make the footwear portion on top do side direction and motion longitudinally with respect to the frame part of bottom.Bottom and lower frame part also can be single molded assemblies.

The present invention also can comprise a speed control unit, comprises at least one but a pressure plare above two preferably in roller in upright arrangement.Pressure plare is subjected to deviating from the bias voltage of roller in upright arrangement on vertical substantially direction.When the actuating speed control device, pressure plare is forced to downwards until at least one roller in upright arrangement of contact.The driving of speed control can use a bar or a cable driving mechanism to finish.

In frame part of the present invention, also comprise a device that is used for for example when damaging or wear and tear, unclamping fast and changing roller in upright arrangement.

The content difference of the present invention and prior art is, can directly see through air and heat with soft, pliable and tough, ventilative, and the material that also can suitably support user's foot simultaneously constitutes the essential part of the footwear portion on top.At some key areas,, use rigid material to form supporting as ankle, the heel member of user's foot.Also can use semi-rigid material at some supporting position.Specifically, the footwear portion on top of the present invention has softness, pliable and tough, ventilative footwear material in conjunction with rigidity or semirigid bottom or ankle joint support.Therefore, it is comfortable that the body skater of footwear portion on top wears, and the bottom of the footwear portion on top and ankle joint support then can form needed supporting, can make the skater easily the roller of in-line roller skate be kept vertical with its rolling surface in sliding.

Used term " rigidity " is to describe the high resistance of plastics to bending or deflection among the present invention, and term " semi-rigid " though be to describe that material can resist big deformation force, also can crooked or temporary transient distortion under effect more energetically greater than the normal forces that run in using." thermoformable " is meant rigidity and semi-rigid material, and under the higher temperature of the temperature that generally runs in being higher than roller skating in upright arrangement, the appropriateness that becomes is pliable and tough and can be shaped.

In general, in in-line roller skate, the use that combines with soft, pliable and tough, breathable material of " rigidity " of thermoformable and " semi-rigid " plastics so that bigger comfortableness to be provided, and is not lost the acquired supporting of use " rigidity " material.Therefore, obviously term " rigidity " and " semi-rigid " not only can refer to use type of material and hardness in in-line roller skate, and refer to the thickness of material.Equally, term " non-rigid ", " softness " and " pliable and tough " describes the Web materials of leather, cloth or various density, it has certain flexible, and with " rigidity " and " semi-rigid " when material is compared, therefore " giving in " is in them,, when closing on the placement of skater foot, more comfortable to the skater.Term " ventilative " is meant the material that air passes through easily, and is different from substantially and can not see through air, and the molded plastics of rigidity or semi-rigid type perhaps refers to be provided with simply the material of passage for circulation of air.

Others of the present invention comprise the jockey that is used for the bottom of in-line roller skate is connected in lower frame.Jockey can compensate upper of a shoe with respect to the side direction of lower frame and vertically adjusting, and comprises pin and hook, so that when assembling upper of a shoe and lower frame are suitably aimed at.Bottom and lower frame also can be single molded assemblies.
