Description

Be exclusively used in skating shoe brake apparatus

The utility model relates to a kind of ice skate with brake apparatus, and this ice skate comprise a shoe cover of being made up of 1/4th shoe covers that are articulated in an overcoat, and this overcoat links to each other with the supporting shoe rack of one or more wheels again.

At present, in known roller skate, no matter be to constitute by a shoe cover that links to each other with the supporting member that is used for two pairs of wheels that are parallel to each other, still be to be made of a shoe cover that links to each other with the supporting shoe rack that is used for one or more wheels that align, problem all has the felt pan that will brake described wheel in order to regulate described skating shoe speed.

Therefore, well-known, use suitable liner or the cushion block generally made by rubber, these liners or cushion block are arranged on the toe or the heel area of shoe cover.When the user tilted shoe cover forward or backward, the free end of liner or cushion block cooperated with ground, thereby reached the purpose of braking.

Therefore but these solutions are not best, because they require the user to rotate the roller-skating shoe cover, and rotate the shoe rack that links to each other with shoe cover at toe or heel place, and this can cause unbalance, falls thereupon.

United States Patent (USP) 1,402,010 also is well known, and it has disclosed a kind of roller skate that is provided with a belt, and this belt is fixed on the ankle zone of user's shank, and is connected with a bar.

To the back, crooked then, laterally acting on shank, in the ankle zone, link to each other with a lever system in its end, this lever system is articulated in a tablet that protrudes in the wheel bearing shoe rack to described bar up to it around shank.

Described lever system protrudes in the back of shoe rack, and be connected in its shape basically with below contrate wheel (facing wheel) sweep near complementary flat board.

This solution does not overcome the deficiency: at first, between belt and shank relative motion can take place in whole motion process, this can feel under the weather when using ice skate.

In addition, drive flat board each time, user's his shank of bending backward surpasses certain angle, can not effectively and easily change this condition of work

In addition, each user has specific shape of leg, therefore, brakes with different anglec of rotation acquisitions for the bar of equal length.

In addition, described bar rests and is pressed in the ankle zone, and this can make the user uncomfortable or cause once in a while bump.

At last, the wearing and tearing of wheel obviously are very serious.

United States Patent (USP) 4,275,895 are considered to partly solve this shortcoming, and this patent has disclosed a kind of skating shoe brake component with two pairs of wheels that are parallel to each other, and this brake component acts on the wheel of back.

Described brake component is that the tablet that links to each other with shoe cover of position constitutes in the wings, and a blade links to each other with the described tablet of position in the wings, and pivots at the supporting shoe rack place that is being used for shoe cover.

The free end of described blade has a lateral member, forms a pair of C shape part at all lateral ends of this lateral member.Described part is along with rotation backward of giving tablet and trailing wheel in the face of them interact, thereby interacts with the rolling surface of described wheel.

But even like this, this solution also has defective: complex structure in fact, so be difficult to industrialization; In addition, requiring has suitable spring, make tablet get back to paired C shape part not can with the interactional position of wheel, this has increased the complexity of structure again.

In addition, even when giving tablet one minimum rotation backward, and even because accidental motion, the planform of brake component also makes paired C shape part interact with wheel, undesirable braking maneuver will appear like this, therefore, disequilibrium or inharmonic phenomenon just might appear.

At last, C shape part can be accelerated the wearing and tearing of described wheel with the interaction of all wheel rolling surfaces, thereby makes rolling bad, and this constantly changes wheel with regard to inevitable requirement.

United States Patent (USP) 4,300,781 also are well known, and this patent relates to and comprises many skating shoe brake apparatus to the wheel that is parallel to each other.

In addition, it also is included in the brake component that a blade that the rearward end of the supporting shoe rack of shoe cover laterally pivots constitutes, in the face of all cushion blocks of the rolling surface of paired trailing wheel link to each other with the end of described blade.

What a spring that links to each other with the supporting member of paired front-wheel formed contrast is, makes the rope of blade rotation drive brake component with one, thereby all cushion blocks are moved and contacts with the rolling surface of paired trailing wheel.

Rope can be by all rings or the handle drives that link to each other with a belt, and this belt is arranged on user's shank by temporary transient jockey.

But this solution has more serious defective: at first, because the user has to carry out inharmonic motion, the driving of brake component may cause losing coordination in motion process.

In addition, when tractive force acted on Zhu Huanshang, belt may separate with shank, thereby hindered braking maneuver.

In a word, in the process of driving fast, a loosening rope that may be hooked suddenly can appear, particularly because the coordinated movement of various economic factors meeting of arm and leg makes leg motion laterally regularly.

Therefore, target of the present utility model is, provide one be used for structure very simple, be convenient to industrialized skating shoe brake apparatus, to eliminate the defective in the above-mentioned known ice skate.

In the scope of above-mentioned target, a free-revving engine provides a kind of brake apparatus, and this brake apparatus is driven under the situation of actual needs by the user, thereby can not brake suddenly.
