Technical field
The present invention relates to the devices that one kind can slide, and particularly, the present invention relates to a kind of roller skates.
Background technique
Popular two kinds of roller skates, i.e. straight-line roller skate and double-row type roller skate currently on the market.Straight-line roller skate one
As tool there are three or four rolling, these idler wheels each other front and back form a line.Double-row type roller skate is commonly referred to as ice skate, is had
Two horizontal shafts, a shaft are arranged in the front of roller skate, another shaft is arranged in the rear portion of roller skate, each shaft
An idler wheel is respectively received at its both ends.Both roller skates, with frame, installation at least two idler wheels on said frame and
Braking system, the frame include bracket and wear part, and the bracket receives the idler wheel, and the part that wears is arranged in the branch
For receiving the foot or shoes of user on frame, the braking system includes driving device and drives work by the driving device
The brake of work.
As all forward mechanisms, carrying out braking to straight-line roller skate or double-row type roller skate makes it slow down or stop
It is only critically important problem, because this is related to the enjoyment that the safety guarantee of user, the comfort used and user enjoy.

In the present embodiment, the knee joint of user flexes to complete straight position from bending position shown in FIG. 1, and first
Component 511 needs rotational angle φ counterclockwise, and when first component 511 is located at the position that angle φ is 0, i.e., knee closes
When section stretches completely, the tension in tension lines 61 is maximum value.Of the obvious tension lines 61 when knee joint is in straight configuration
Power is greater than the tension when knee joint is in bending state, therefore when user needs braking roller skate, as long as knee joint is stretched
Directly it is achieved that because at this moment second supporting element 8 of this 8 brake components of 8 brake components 7 and support is together in tension lines 61
It is moved backward under the driving of tension, so that brake component 7 is in contact with the wheel rim 22 of idler wheel 2, to generate brake force;Conversely, when making
When user needs roller skate to slide, as long as knee joint bending is to certain degree it is achieved that because at this moment in tension lines 61
Tension it is smaller, under the action of restoring spring 84, brake component 7 be detached from idler wheel 2 wheel rim 22, i.e., no Braking is in rolling
On wheel 2.
Since the knee joint flexion and extension of user can be carried out easily and quickly and can provide very big energy, this
The roller skate of invention can easily and fast and reliably carry out braking.
Fig. 5 shows second embodiment of the invention.From fig. 5, it is seen that the present embodiment and shown in FIG. 1 first
A embodiment is similar, and only the present embodiment increases the first supporting element 9 on the basis of one embodiment.First supporting element 9
Lower end by shaft 91 and wear part 4 rotation connection, the upper end of the first supporting element 9 is connect with second component 521.According to need
It wants, the lower end of the first supporting element 9 can also be rotatablely connected with bracket 3.
In the present embodiment, the first supporting element 9 is a hollow support rod, and second component 521 can protrude into first
The inside of strut 9 can simultaneously be moved along the length direction of first support bar 9, can conveniently adjust entire 5 institute of driving device in this way
The height at place is conducive to meet its knee joint position in people's use of different height, is also beneficial to roller skate when not in use, reduces
Height locating for driving device 5 is to reduce the occupied space of entire roller skate.
Fig. 6 shows third embodiment of the invention.It will be seen from figure 6 that the present embodiment and shown in fig. 5 second
A embodiment is similar, and only the structure of the second component 521 of the driving device 5 of the present embodiment and the connection position of tension lines 61 are equipped with
Institute is different.
In the present embodiment, second component 521 includes first point of component, 555, second points of components 556, is fixed on first point
Impeller 557 and locating piece 559 on component 555, wherein first point of component 555 passes through shaft 53 and second point 556 turns of component
It is dynamic to connect, the through-hole 558 of arc is provided on first point of component 555, locating piece 559 can be in the through-hole 558 of arc laterally
Mobile, so that the position that locating piece 559 is fixed on first point of component 555 can change, the locating piece 559 of the present embodiment is one
