Anchoring apparatus for mast on vehicle

Abstract

An anchoring apparatus for the mast on vehicles is adopted for use on an extendable mast mounted on a movable vehicle body to prevent the erected and extended mast from wobbling in the wind. The anchoring apparatus has a plurality of support posts located around the periphery of the vehicle body and equally spaced from the mast. The support post may include an upper support post and a lower support post. The lower support post may movably rest on the ground surface to support the vehicle body and have a bottom end linked tightly by a steel cable or rod to a neighboring bottom end. The upper support post may be movably extended outwards from the vehicle roof with an outer end linking to the top end of the mast by a steel cable. The outer end of the upper support post and the bottom end of the lower support post may be linked tightly by a steel cable under tension. Thereby the mast can be erected and anchored steadily.

I claim:  
     
         1 . An anchoring apparatus for a mast of vehicles for anchoring the mast which is extendable to maintain the mast steadily when erected without wobbling, comprising: 
 a plurality of support posts each having one end movably and detachably engaged with the periphery of a vehicle's roof and another end extended outwards to link to the top end of the mast through a flexible and tension-adjustable support members winding thereon.    
     
     
         2 . The anchoring apparatus of  claim 1 , wherein the support posts are lower support posts extending downwards having respectively one end movably and pivotally engaged with the periphery of the vehicle's roof and another end extended to rest on the ground surface where the vehicle stations.  
     
     
         3 . The anchoring apparatus of  claim 2 , wherein another ends of the support posts resting on the ground surface are linked to each other with flexible members under tension.  
     
     
         4 . The anchoring apparatus of  claim 1 , wherein the support posts include respectively an upper support post and a lower support post that have respectively one end movably engaged with the periphery of the vehicle's roof, the rope being fastened to the top end of the mast and linked to a distal end of the upper support post which extends outwards, and the lower support post being directed downwards to rest on the ground surface where the vehicle stations.  
     
     
         5 . The anchoring apparatus of  claim 4 , wherein the upper support post is extended outwards from the periphery of the vehicle's roof where it is pivotally engaged.  
     
     
         6 . The anchoring apparatus of  claim 4 , wherein the lower support posts have respectively one end resting on the ground surface that are linked to each other under tension.  
     
     
         7 . The anchoring apparatus of  claim 4 , wherein the upper support posts have respectively one end extended outwards that are linked to each other with flexible members under tension.  
     
     
         8 . The anchoring apparatus of  claim 1 , wherein each of the support posts is a L-shaped post including an upper support post and a lower support post joined on a connection end which is movably engaged with the periphery of the vehicle roof, the upper support post having one end extended outwards to link to the top end of the mast through a rope and the lower support post having one end rested on the ground surface where the vehicle stations.  
     
     
         9 . The anchoring apparatus of  claim 8 , wherein the lower support posts have respectively one end rested on the ground surface that are linked to each other with flexible members under tension.  
     
     
         10 . The anchoring apparatus of  claim 8 , wherein the upper support post and the lower support post have respectively one end extending outwards that are linked to each other with flexible members under tension.  
     
     
         11 . The anchoring apparatus of  claim 8 , wherein the extending end of the upper support post engages with a pulley.  
     
     
         12 . The anchoring apparatus of  claim 11 , wherein the flexible member is pendent from the top end of the mast and winds around the pulley to connect to the grounding end of the lower support post.  
     
     
         13 . The anchoring apparatus of  claim 1 , wherein the support post is an upper support post extending outwards having one end movably and pivotally engaged with the vehicle's roof periphery and another end extended outwards to engage with a flexible member which links to the top end of the mast and connects to the periphery of the bottom section of the vehicle.  
     
     
         14 . The anchoring apparatus of  claim 13 , wherein the one end of the support post extended outwards is linked to each other with flexible members under tension.
