Retracting roller module of skating shoes

Abstract

A retracting roller module for skating shoes is disclosed, and the retracting roller module comprises a base seat, a positioning shaft, a front roller module and a rear roller module pivotally mounted onto the shaft, and a control mechanism for controlling the retracting and extending of the front and rear roller module, characterized in that the front section of the lateral plate of the base seat is mounted with the positioning shaft which mounts a rear roller support frame, rubber rim, a side linear, a middle linear, and a front roller support frame, and the rear roller support frame and the front roller support frame are pivotally mounted onto a shaft hole of the lateral side plate, and the middle section of the lateral side plate is provided with guiding channel having a rear positioning hole and a front positioning hole, the guiding channel utilizes the driving rod of the control mechanism to mount a mechanical seal, a front interlink rod, an engaging block, a rear interlink rod, a control rod and an extension spring and a specific screw nut is used for positioning thereto, thereby the outward pulling of the control rod will retract the front and rear roller and the pulling and rear pushing of the control rod extends the front and rear roller module.

1 . A retracting roller module for skating shoes having a base seat, a positioning shaft, a front roller module and a rear roller module pivotally mounted onto the shaft, and a control mechanism for controlling the retracting and extending of the front and rear roller module, characterized in that the front section of the lateral plate of the base seat is mounted with the positioning shaft which mounts a rear roller support frame, rubber rim, a side linear, a middle linear, and a front roller support frame, and the rear roller support frame and the front roller support frame are pivotally mounted onto a shaft hole of the lateral side plate, and the middle section of the lateral side plate is provided with guiding channel having a rear positioning hole and a front positioning hole, the guiding channel utilizes the driving rod of the control mechanism to mount a mechanical seal, a front interlink rod, an engaging block, a rear interlink rod, a control rod and an extension spring and a specific screw nut is used for positioning thereto, thereby the outward pulling of the control rod will retract the front and rear roller and the pulling and rear pushing of the control rod extends the front and rear roller module.  
     
     
         2 . The retracting roller module for skating shoes of  claim 1 , wherein the positioning shaft is mounted with a rubber rim for use as shock absorbing elastic body between the front roller support frame and the rear roller support frame.  
     
     
         3 . The retracting roller module for skating shoes of  claim 1 , wherein the inner side of the rear roller housing is a spaced ring provided with recess for the positioning at the protruded teeth at the lateral plate in the course of retraction of the roller module.  
     
     
         4 . The retracting roller module for skating shoes of  claim 1 , wherein the front interlink rod is provided with a long through hole and an engaging block and a driving rod are pivotally mounted to the rear positioning hole of the lateral plate, and the front end of the lateral plate is provided with a through hole so as to connect an inner tube, spaced tube and the upper end of the front roller support frame to the through hole using rivet so that a relatable hinge connection is obtained.  
     
     
         5 . The retracting roller module for skating shoes of  claim 1 , wherein a threaded hole at the bottom section of the rear interlink rod utilizes a linear and screw to form an actuating knot at the shaft hole of the middle section of the rear roller support frame, and the through hole thereon has a control rod passed through and pivotally mounted at the driving rod.  
     
     
         6 . The retracting roller module for skating shoes of  claim 1 , wherein the two ends of the driving rod of the control mechanism is mounted in sequence with a mechanical seal, front interlink rod, an engaging block, a lateral plate, a rear interlink rod, a control rod and an extension spring and is then locked with a specific screw nut.  
     
     
         7 . The retracting roller module for skating shoes of  claim 1 , wherein the inner side of the engaging block is provided with a protruding element for supporting the long through hole of the front interlink rod, and the external lateral side thereof is provided with a protruding piece for the mounting of the guiding channel of the lateral plate, and the center of the external side is provided with the engaging slot for the mounting of the control rod.  
     
     
         8 . The retracting roller module for skating shoes of  claim 1 , wherein the control rod is mounted onto the driving rod such that a fore end passes through the through hole of the rear interlink rod and the rear positioning hole of the lateral side plate and the engaging slot of the engaging block, and the inner hole thereof is mounted with extension spring, and a specific screw nut is used for locking such that the control rod is being moveable to the sides.  
     
     
         9 . The retracting roller module for skating shoes of  claim 1 , wherein the rear partitioned plate is mounted between the rear section of two lateral side plates, and the vertical hole is used for the mounting of a braking body.  
     
     
         10 . The retracting roller module for skating shoes of  claim 1 , wherein the bottom heel section at the rear section of the two lateral side plates is used as the walking heel section in the course of retraction of the front roller and the rear roller.
