Definitions

• Anchoring device for elongated member e.g. telegraph pole .
• the present invention relates to an anchoring device for elongated members, for example poles. Examples of these are telegraph poles and/or lampposts.
• the anchoring device is designed as an elongate unit that at one end has a part that is subjected to downward driving force in order to make possible the downward driving of the unit into the ground during a first stage of the anchoring process.
• the anchoring principle must be simple inasmuch as the anchoring unit must be able to be driven into the ground using a conventional pile driver.
• the anchoring device must be of a relatively moderate length in order to be easy to handle and easy to store. The invention also solves this problem.
• the anchoring device must be able to operate with an anchoring process comprising at least two stages where the device or unit as such is driven downwards into the ground in a first stage and thereafter an additional anchoring capability is implemented in a second stage of the anchoring process.
• the construction of the anchoring device and the means it contains to achieve this must operate consistently and reliably in different anchoring situations .
• the invention also solves this problem.
• a third stage of the anchoring process must be able to be implemented.
• the cavities in the unit for the actuating functions and the functions carrying out the second stage of the anchoring process are to have a construction that permits the abovementioned third stage of the anchoring process that can consist of filling the cavities in question with material, cement, etc., in order to seal the second stage of the anchoring process.
• the invention also solves this problem.
• an anchoring device has a number of elongated elements, for example, 2, 3 or 4 , each of which during the first stage of the anchoring process occupies a position principally inside the unit. Further characteristics are that the elongated element (s) is/are designed so that by means of a force applied via the abovementioned part they are pushed out completely or partially from the unit in a direction that is different to the direction of the longitudinal axis of the unit, all with the aim of increasing the anchoring capability by means of interaction with the ground.
• the elongated elements consist of elongated springs that are fastened together at the top in pairs and that, in their withdrawn positions in the unit, extend towards the front end or front tip of the unit.
• the unit is designed with side openings through which the arms can be pushed out by the application of the abovementioned forces.
• two pairs of elongate springs are designed to form the elongated elements.
• the springs in each pair are held together by cross-pieces.
• the arms are arranged so that their tips protrude slightly through the openings.
• the elongated elements or arms are mounted or centred inside an opening in the unit by means of a mounting rod, elongated element, to which the elongated elements or arms are attached at their upper ends.
• the arms and the mounting rod can be moved lengthways relative to the unit so that when a force is applied the rod and the arms are pressed down towards the free end or tip of the unit.
• the pressing-down movements result in the arms being pushed out of the arrangement of the openings in directions or at angles that differ from the direction of the longitudinal axis of the unit. In their fully-extended positions the arms lie in positions which are essentially ' at right angles to the longitudinal axis of the unit.
• an internal duct between the position of the upper parts of the elongated elements when these are inside the unit and the abovementioned part of the unit.
• An element that can move lengthways relative to the unit is inserted in the internal duct in order to transmit to the elongate arms the exerted forces that are transmitted from the top side of the anchoring device (above the surface of the ground) to the abovementioned element which has been moved lengthways.
• the unit is provided with a pointed part that is provided with an internal guide duct for the mounting rod of the elongate arms (or the like) .
• the unit is designed with fixing attachments for sleeve parts that enclose the bottom of the elongated member (the pole) , which sleeve parts can have a mainly square or circular cross-section.
• the internal cavities in the unit are filled with filling material that retains the arms or the elongated elements in well-defined protruding positions.
• a first stage that constitutes a downward driving stage
• a second stage that effects the pushing out of the elements into the ground
• a third stage for the locking of such completely or partially protruding elements.
• the downward driving stage is made easier by means of the rather elongate unit being provided in a known way with a pointed material-filled front part that merges into a principally cylindrical part that holds at the top the attachment device or attachment arrangement for the pole in question.

• the abovementioned cavities and ducts are designed with a common longitudinal axis 8.
• the abovementioned part 4 is provided with an impact surface 4a and attachment devices 9 fastened to this, which in the exemplary embodiment can be four in number and are evenly spaced around the perimeter of the impact surface 4a.

• the pairs of arms are attached via the abovementioned cross-pieces 14 and 15 to a mounting rod 16 that extends inside and through the abovementioned cavity 5 and is partially mounted in the duct 7 in the initial position.
• the mounting attachment protrudes somewhat above the cross-pieces 14,15 and the element 17 which can be moved lengthwise interacts with the abovementioned mounting attachment.
• the spring-like elements 10 and 11 have tips 10a and 11a that in the initial position shown protrude slightly through the side openings 18,19 arranged in the unit 1.

• the abovementioned arms are slightly curved at the abovementioned tips .
• the arms 12 and 13 have a corresponding shape to the arms 10 and 11 and are situated at corresponding side openings to the openings 18 and 19.
