The invention relates to inline skates and more particularly to an inline skate including a shock absorber having a length adjustable biasing member (e.g., torsion spring) so that shock and jarring of the inline skates can be greatly decreased when an individual wears the inline skates to move quickly across a surface.
Conventionally, the frame of an inline skate is made of plastic and is light. A skate boot is mounted on the frame. A plurality of holes are provided through either downward extending flange of the frame. Front and rear wheels are rotatably mounted between two opposite front holes and two opposite rear holes respectively.
However, no shock absorber or the like is provided by the conventional inline skate. Thus, shock and jarring of the inline skates are increased greatly when an individual wears the inline skates to move quickly across a surface with irregularities. This can decrease skating speed and may further cause pain to the user's knees and/or other parts of the legs if sufficient care is not taken.
Thus, the need for improvement still exists.
It is therefore one object of the invention to provide an inline skate comprising a skate boot; a front wheel mount secured to a front portion of a bottom of the skate boot; a front wheel rotatably secured to the front wheel mount; a rear wheel mount secured to a rear portion of the bottom of the skate boot; a rear wheel rotatably secured to the rear wheel mount; a shock absorber disposed between the front wheel mount and the rear wheel mount; a protective member disposed on the shock absorber; and a brake block attached to a rear end of the skate boot with both the rear wheel mount and the rear wheel disposed below; wherein the shock absorber comprises two sets of a positioning member secured to the bottom of the skate boot; a threaded adjustment member disposed through either the rear wheel mount or the front wheel mount; a biasing member; a first bifurcation element disposed through the biasing member, the first bifurcation element having one end secured to an end of the threaded adjustment member and the other two ends secured to the other end of the biasing member; and a second bifurcation element disposed through the biasing member, the second bifurcation element having one end secured to the positioning member and the other two ends secured to one end of the biasing member.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
The shock absorber 6 as the subject of the invention is discussed in detail below. The shock absorber 6 comprises two sets of components in which one set of components comprises a positioning member 61 secured to the skate boot 1; an adjustment member (e.g., an adjustment screw) 62 having a threaded shank 621 adjustably fastened through a threaded hole (not shown) in the rear wheel mount 3; and a biasing assembly 63 including a biasing member (e.g., torsion spring) 632, a first bifurcation element 631A disposed through the biasing member 632, the first bifurcation element 631A having one end secured to an end of the adjustment member 62 and the other two hooked ends secured to the other end of the biasing member 632, and a second bifurcation element 631B disposed through the biasing member 632, the second bifurcation element 631B having one end secured to the positioning member 61 and the other two hooked ends secured to one end of the biasing member 632.
An individual may use one hand to clockwise rotate the adjustment member 62. And in turn, the first bifurcation element 631A is pulled toward the rear wheel mount 3. Thus, the biasing member 632 is compressed. As a result, a damping force of the shock absorber 6 is increased.
To the contrary, the user may use one hand to counterclockwise rotate the adjustment member 62. And in turn, the first bifurcation element 631A is pulled away from the rear wheel mount 3. Thus, the biasing member 632 is expanded. As a result, a damping force of the shock absorber 6 is decreased.
The other set of components of the shock absorber 6 are the same as that described above and further, adjustment of the damping force of the shock absorber 6 by means of the other set of components of the shock absorber 6 is the same as that described above. Thus, a detailed description thereof is omitted herein for the sake of brevity.
It is envisaged by the invention that the shock absorbers 6 can greatly decrease shock and jarring of the inline skates when an individual wears the inline skates to move quickly across a surface. Further, the protective member 7 may enable the inline skate to slide obliquely when the inline skate collides with a foreign object. Furthermore, length of the biasing member 632 is adjustable to accommodate wearers of different weights. In addition, the damping force of the shock absorber 6 can be increased or decreased by adjustment.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
