Remote-control movable bump for temporary traffic-control purpose

Abstract

A remote-control movable bump for temporary traffic-control purpose includes a movable and combinable main body of trapezoid shape so as to define a slope on front and back side, a plurality of vertical slots formed spaced apart in one of the slopes, a shaft rotatably disposed in a center of the main body having a hexagon recess in one end and a protrudent rectangular recess on the other end engageable with a rectangular axis of an alternately rotated motor, a plurality of tipped blades integrated with the shaft and engaged within the vertical slots respectively and a remote sensor to actuate the motor which operates the shaft to rotate for lifting the tipped blade up for about 45°.

1 - 3 . (canceled)  
   
   
       4 . A movable traffic bump for temporary traffic-control purpose, comprising a single unit, wherein the unit comprises: 
 A) a movable main body of predetermined length, height, and width, forming a first trapezoid cross section end surface, and a second trapezoid cross section end surface, so as to define a front slope surface, a horizontal top surface, a horizontal bottom surface, and a back slope surface, 
 i) said front slope surface having a horizontal lower leading edge, a right side sloped edge, a left side sloped edge, and a horizontal upper trailing edge,  
 ii) said horizontal top surface pending from said front slope upper trailing edge, 
 a) having a front side leading edge contiguous with the front slope upper trailing edge, a left side edge pending from the left edge of the front sloped surface, a right side edge pending from the right edge of the front sloped surface, and a backside trailing edge,  
 
 iii) said back slope surface pending from said horizontal top surface backside trailing edge, 
 a) having a sloped surface having a horizontal leading edge contiguous with the horizontal top surface backside trailing edge, a right side edge, a left side edge, and a horizontal lower trailing edge;  
 
   B) a plurality of rectangular vertical slots, wherein 
 i) each individual slot is cut into the front sloped surface and the top horizontal surface,  
 ii) the slots run parallel to the right and left edges of both the front sloped surface and the top horizontal surface,  
 iii) the slots each define a void within the movable main body;  
   C) an orifice in each of said trapezoidal ends of the main body, made in registry with each other;    D) a pair of bearing engaged within said orifices;    E) a shaft disposed within the main body and movably engaged within both of said bearings;    F) said shaft having a proximal end and a distal end, wherein 
 i) the distal end is mounted to so position the distal end of the shaft flush with the first trapezoidal end surface, further, the distal end of the shaft has a hexagonal recess therein,  
 ii) the proximal end 
 a) is mounted to so position the proximal end of the shaft to protrude from the second trapezoidal end surface to approximately the depth of the hexagonal recess of the distal end of the shaft,  
 b) has an outer surface defining a hexagonal shape,  
 c) has a rectangular recess,  
 
   G) a plurality of tipped blades, movably deployed within the voids defined by the plurality of rectangular vertical slots, and fixedly attached to the shaft disposed within the main body, wherein the tipped blades may be engaged to protrude from the vertical slots by rotating the shaft.    
   
   
       5 . The movable traffic bump according to  claim 4 , further comprising: two or more units, wherein the hexagonal recess of the distal end of one unit operably engages the protruding proximal end of a second unit in such a manner that the trapezoidal ends of the units flushly contact to form a uniform, multi-unit movable bump.  
   
   
       6 . The movable traffic bump according to  claim 4 , further comprising a motorized actuating unit operably engaging the protruding proximal end, wherein the motorized actuating unit may be remote controlled.  
   
   
       7 . The movable traffic bump according to  claim 5 , further comprising a motorized actuating unit operably engaging the protruding proximal end, wherein the motorized actuating unit may be remote controlled.
