Title: Infant pushchair wheel support

Description:
OBJECT OF THE INVENTION  
      The invention relates to an infant pushchair wheel support.  
     BACKGROUND OF THE INVENTION  
      Some models of foldable pushchairs have been already known for years which comprise only three wheels, i.e. two back ones and a central front one being in some cases a castoring wheel.  
      This very applicant is the holder of the Spanish Utility Model No. 200202189 (ES-1052792) having as its object an infant pushchair of the above mentioned type having features improving the makeup of the forward lower portion where the castoring wheel is to be arranged.  
     SUMMARY OF THE INVENTION  
      It is the object of this invention to improve the front wheel arrangement by simplifying its support and providing it with a mudguard and means allowing to better arrange the active portion of the disc brake belonging to said wheel.  
      The support has for such a purpose been made up as an only arm being laterally arranged with respect to the wheel, said arm being upperly elbowed above said wheel and having the mudguard solidly attached to the lower end of this elbowed portion.  
      Said lateral arm has been provided with an appendage to which the active portion of the disc brake is solidly attached, said brake being actuated by a rope passing through the inside of said arm and emerging through a hole of said arm to thereupon engage said active portion of the brake.  
      These and other characteristics will be best made apparent by the following detailed description whose understanding will be made easier by the accompanying sheet of drawings showing a practical embodiment being cited only by way of example not limiting the scope of the present invention. 
    
    
     DESCRIPTION OF THE DRAWINGS  
       FIG. 1  in a perspective view illustrates the forward lower portion of a pushchair comprising the wheel support being the object of this invention;  
       FIG. 2  is a front view of the wheel and its support; and  
       FIG. 3  is a close perspective view showing the upper portion of said support. 
    
    
     DETAILED DESCRIPTION  
      According to the drawings the infant pushchair comprises a front wheel ( 1 ) being provided with a pneumatic tire ( 2 ) and fitted to the lower portion of the converging front legs (3) and (4) by means of a footrest ( 5 ) at its forward portion having an extension ( 6 ) being vertically bored thus forming the passage allowing to fit the pin being integral with the support to which the wheel is fitted.  
      This support is characteristically made up by an arm ( 7 ) being laterally arranged with respect to the wheel ( 1 ), said arm being upperly elbowed (at  8 ) above said wheel and having a mudguard ( 9 ) solidly attached to the lower end of said elbowed portion.  
      The wheel ( 1 ) has disc-braking means ( 10 ) being actuated by a rope ( 11 ), the active portion ( 12 ) of the brake being solidly attached to a forwardly arranged appendage ( 13 ) of the arm ( 7 ), the rope ( 11 ) passing through the inside of said arm and emerging therefrom through a hole ( 14 ) to thereupon engage said active portion ( 12 ).  
      A control ( 15 ) belonging to the means allowing to remove the wheel ( 1 ) from the corresponding axle is laterally arranged at the lower end of said arm ( 7 ).  
      The rotation of the pin being integral with the elbow ( 8 ) of said arm ( 7 ) can be locked by means of a lock being provided with an outer, lateral control ( 16 ), said pin being arranged at the extension ( 6 ) of the footrest and for such a purpose being provided with bearings being duly protected by covers (17) and (18).
