Damper device for in-line skate

Abstract

A damper device for an in-line skate is provided, in which an impact caused by a non-uniform road surface during skating is absorbed and buffered in order to realize more stable skating. The damper device includes: a hinge member which is installed at the lower-front portion of a boot and the front portion of a wheel frame, and which is rotatably connected therewith; and a damper which is installed between a fixed bracket which is fixed at the lower-rear portion of the boot and which is extended down to the rear side of an ankle and the rear portion of the wheel frame.

1 . A damper device for an in-line skate including a boot, a wheel frame installed in the lower portion of the boot, and a plurality of wheels which are rotatably mounted in the wheel frame, the damper device comprising: 
 a hinge member which is installed at the lower-front portion of the boot and the front portion of the wheel frame, and which is rotatably connected therewith; and    a damper which is installed between a fixed bracket which is fixed at the lower-rear portion of the boot and which is extended down to the rear side of an ankle and the rear portion of the wheel frame.    
   
   
       2 . The damper device for an in-line skate according to  claim 1 , further comprising a fixing plate which is installed in the lower portion of the boot; and a fixing pin which is installed so as to be detachably coupled via fixing holes of the fixing plate and the wheel frame.  
   
   
       3 . The damper device for an in-line skate according to  claim 1 , wherein the damper comprises: a shock absorber which is integrally installed in the wheel frame, in which a strut rod which is withdrawn upwards is connected with a fixing bracket; a lower variable spring support being an adjuster which is rotatably installed around the lower portion of the shock absorber and which comprises a number of teeth which are engaged with a fixing protrusion in multi-step, to thereby control height; and a coil spring installed between the fixing bracket and the lower variable spring support.  
   
   
       4 . An in-line skate comprising: 
 a boot;    a wheel frame installed in the lower portion of the boot;    a plurality of wheels which are rotatably mounted in the wheel frame;    a hinge member which is installed at the lower-front portion of the boot and the front portion of the wheel frame, and which is rotatably connected therewith; and    a damper which is installed between a fixed bracket which is fixed at the lower-rear portion of the boot and which is extended down to the rear side of an ankle and the rear portion of the wheel frame.    
   
   
       5 . The in-line skate according to  claim 4 , further comprising a fixing plate which is installed in the lower portion of the boot; and a fixing pin which is installed so as to be detachably coupled via fixing holes of the fixing plate and the wheel frame.  
   
   
       6 . The in-line skate according to  claim 4 , wherein the damper comprises: a shock absorber which is integrally installed in the wheel frame, in which a strut rod which is withdrawn upwards is connected with a fixing bracket; a lower variable spring support being an adjuster which is rotatably installed around the lower portion of the shock absorber and which comprises a number of teeth which are engaged with a fixing protrusion in multi-step, to thereby control height; and a coil spring installed between the fixing bracket and the lower variable spring support.
