Multiple head sweeping device

Abstract

An efficient sweeping device has a handle with a gripping end and a sweeping end. The sweeping end has at least a first brush head and a second brush head. The two brush heads are disposed so that a) when the sweeping end is pressed firmly against a ground surface ends of bristles of each of the at least two brush heads contact the ground surface; and b) ends of the bristles on each broom head contact the ground surface, with ends of bristles on the first broom head being more distal from the gripping end than ends of bristles of the second broom head. The first broom head may be able to pivot away from the second broom head when the device is held relatively horizontally over the ground surface.

1 . A sweeping device comprising a handle having a gripping end and a sweeping end, 
 the sweeping end comprising at least two brush heads of a first brush head independently attached to the handle and a second brush head independently from the first brush head attached to the handle, the two brush heads disposed so that: 
 a) when the sweeping end is pressed firmly against a ground surface, bristles of each of the at least two brush heads contact the ground surface; and  
 b) ends of the bristles of each of the two brush heads contact the ground surface, with the ends of bristles on the second brush head being more distal from the gripping end than the ends of bristles of the first brush head.  
   
   
   
       2 . The sweeping device of  claim 1  wherein a direction between an end of the gripping end and an end of the sweeping end is considered a length of the device and there is an average separation between closest ends of bristles on the first brush head and ends of bristles on the second brush head of between 3 and 50 cm and the first and second brush heads do not pivot with respect to the handle.  
   
   
       3 . The sweeping device of  claim 1  wherein a direction between an end of the gripping end and an end of the sweeping end is considered a length of the device and the bristles of the first brush head are closest to the gripping end of the device, the first brush head being relatively closer to the ground surface when the device is in a sweeping position, and the first brush head is able to pivot away from the second brush head when the device is held relatively horizontally over the ground surface with the first brush head closest to the ground surface in comparison with the second brush head.  
   
   
       4 . The sweeping device of  claim 1  wherein the handle comprising the gripping end and at least the second brush head is physically secured proximally at the sweeping end of the device.  
   
   
       5 . The sweeping device of  claim 4  wherein the second brush head may be removed and reattached to the elongate handle without damage to the elongate handle or the second brush head.  
   
   
       6 . The sweeping device of  claim 4  wherein the first brush head may be removed and reattached to the elongate handle without damage to the elongate handle or the first brush head.  
   
   
       7 . The sweeping device of  claim 6  wherein the second brush head may be removed and reattached to the elongate handle without damage to the elongate handle or the second brush head.  
   
   
       8 . The sweeping device of  claim 1  wherein a locus of ends of bristles on the first brush head and a locus of bristles on the second brush head are each defined by an approximately straight line.  
   
   
       9 . (canceled)  
   
   
       10 . The sweeping device of  claim 1  wherein the handle comprising the gripping end and the second brush head is at an angle with respect to the elongate handle that is closer to parallellity with the handle than an angle between the first brush head and the elongate handle.  
   
   
       11 . The sweeping device of  claim 2  wherein the handle comprising the gripping end and the second brush head is at an angle with respect to the elongate handle that is closer to parallellity with the handle than an angle between the first brush head and the elongate handle.  
   
   
       12 . The sweeping device of  claim 3  wherein there is an elongate handle element comprising the gripping end and the second brush head is at an angle with respect to the elongate handle that is closer to parallellity with the handle than an angle between the first brush head and the elongate handle.  
   
   
       13 . The sweeping device of  claim 4  wherein there is an elongate handle element comprising the gripping end and the second brush head is at an angle with respect to the elongate handle that is closer to parallellity with the handle than an angle between the first brush head and the elongate handle.  
   
   
       14 . The sweeping device of  claim 3  wherein a locking system is present that prevents pivoting of the first brush head until the locking device is positioned into an unlocked position.  
   
   
       15 . The sweeping device of  claim 12  wherein a locking system is present that prevents pivoting of the first brush head until the locking device is positioned into an unlocked position.
