Ground foundation element

Abstract

A ground foundation element ( 2 ) comprising an elongated anchor portion ( 10 ) which is arranged to be placed into the ground during installation and which is arranged to establish a firm connection between the elongated anchor portion and the ground. The ground foundation element further comprises: a first elongated track ( 20, 22 ) fixed to the elongated anchor portion on one side of a plane comprising the longitudinal centre axis of the elongated anchor portion and a second elongated track fixed to the elongated anchor portion on the other side of said plane. The first and second elongated tracks are arranged essentially parallel to each other and offset from each other in a direction which is perpendicular to the longitudinal axes of the first and second elongated tracks and which is perpendicular to said plane. In this way, a ground foundation element is provided which can be used in a ground foundation assembly which provides an adjustable, strong and simple arrangement.

         3 . A ground foundation assembly ( 1 ) suitable for supporting a supported object ( 4 ), for example a vertically aligned post ( 5 ) or a pole, said ground foundation assembly comprising:
 a. a ground foundation element ( 2 ) according to  claim 1 ,   b. a sled ( 3 ) comprising a first and a second opening ( 25 , 26 ),   c. a first fastening element ( 27 ) which passes through the first opening ( 25 ) in the sled and which is engaged with the first elongate track ( 20 , 22 ),   d. a second fastening element ( 28 ) which passes through the second opening ( 26 ) in the sled and which is engaged with the second elongate track ( 21 , 23 ), and wherein   e. said first and second fastening elements ( 27 , 28 ) are arranged to have two modes, an unlocked mode where the fastening elements are slideably engaged with their respective tracks and a locked mode where the fastening elements are fixedly engaged with their respective tracks such in the unlocked mode the sled is able to displace with respect to the elongated anchoring portion and in the locked mode the sled is fixed in position with respect to the elongated anchoring portion.   
     
     
         4 . A ground foundation assembly ( 1 ) according to  claim 3 , characterized in that the assembly further comprises a washer plate ( 30 ) with a first opening ( 31 ) and a second opening ( 32 ), said washer plate being arranged above the sled ( 3 ) and the first fastening element ( 27 ) passing through the first opening ( 31 ) of the washer plate and the second fastening element ( 28 ) passing through the second opening ( 32 ) of the washer plate. 
     
     
         5 . A ground foundation assembly ( 1 ) according to  claim 3 , characterized in that said first and second openings ( 25 , 26 ) in the sled ( 3 ) are elongated slots. 
     
     
         6 . A ground foundation assembly according to  claim 3 , characterized in that the first and second openings in the sled are at least twice as large as the diameter of the portion of the respective fastening element passing through the first and second openings. 
     
     
         7 . A ground foundation assembly ( 1 ) according to  claim 3 , characterized in that each of said first and second fastening elements ( 27 , 28 ) comprise a bolt and a nut. 
     
     
         8 . A ground foundation assembly ( 1 ) according to  claim 3 , characterized in that the sled ( 3 ) comprises a mounting element ( 35 , 36 ) via which the supported element ( 4 ) can be mounted on the sled. 
     
     
         9 . A ground foundation assembly ( 1 ) according to  claim 8 , characterized in that the mounting element ( 35 , 36 ) is arranged to allow the distance between the sled ( 3 ) and the supported object ( 4 ) to be adjusted. 
     
     
         10 . A ground foundation assembly ( 1 ) according to  claim 9 , characterized in that the sled ( 3 ) comprises at least two mounting elements ( 35 , 36 ) which can be adjusted independently of each other, thereby allowing the alignment of the supported object ( 4 ) to be adjusted with respect to the sled ( 3 ).
