Base support for pole

Claim 1

C L A IM S THE CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS 1. A base support for fastening a pole standing off from a foundation, provided with a base member or an anchor body, able to be anchored in a foundation, having below a base wall being attachable in relation to the foundation by a central anchor bolt or a connecting bolt and rotatable around a first rotation axis which is substantially perpendicular to the foundation, above it an all around running side wall and on the top a thru hole surrounded by a circular, ring-shaped .o covering wall proceeding transversally to the base wall and o8oj showing such a dimension that through the thru hole the anchor S. bolt is insertable, and with a pole supporting member Spresenting at its top a connecting area for the pole, below an all around running side wall and at its bottom a mounting wall presenting a circular supporting suarface being complementary to the bearing surface, whereby the mounting wall is provided with a central boring, being situated within the thru hole, "C for permitting a rotation around a second rotation axis proceeding perpendicular to the bearing or supporting surface, whereby the central boring serves for passing through a (,29o fastening bolt and secures the mounting wail to the base wall, ,o thus establishing a firm axial clamp joint between the bearing and the supporting surface, the fastening bolt being axially braced against the mounting wall and accessible through an access opening in the upper area of the pole supporting member, whereby, preferably radially outside the central boring between the annular covering wall and the mounting wall, an axial, dynamically balanced insert connection is provided, being concentric to the second rotation axis, by means of which the base member and the pole supporting member are rotatable around the second rotation axis, but radially immovably connected, characterized in that, for a simultaneous performance of the fastening bolt functioning, the anchor bolt is passed through the central boring of the mounting wall and is, with its head area, in frictionnal connection with a power transmission device transmitting at least partially the component running perpendicularly to the bearing and supporting face of the tension force operating in axial direction of the anchor bolt the power transmission device being, in all relative rotary positions of the base member and of the pole supporting member in a jam-free frictional connection proceeding perpendicular to the mounting wall and o in axial direction of the anchor bolt respectively, as well with the pole supporting member as with the anchor bolt os i 2. A base support for pole according to claim 1, characterized in that the power transmitting device is developed as a tapered ring having a wedge angle (C) o equalling the angle between the two rotation axes through which the anchor bolt extends, and at the upper surface of which, proceeding perpendicular to the axis of.the anchor bolt the head of the anchor bolt sits close, whereby the lower wedge surface preferably P0 oo sits close on all sides at the oblique mounting wall 3. A base support for pole according to claim 1, characterized in that the power transmitting device is developed as a spherical supporting member provided in the head area of the anchor bolt the center of which coincides with the intersecting point of the two rotation axes and as hereto complementary spherical surface sections at the mounting wall of the pole supporting member whereby the spherical supporting member and the spherical surface sections extend and are disposed in such a way that, on the one iand, they are capable of transmitting the tension forces, and, on the other Preferably extends upwards and downwards at least as ar as the spherical surface sections will reach. Use of a ball and -17 hand, to a free relative rotation of the base member permit and the pole supporting member with the anchor bolt being relaxed, and that the spherical supporting member preferably extends upwards and downwards, at least as far as the spherical surface sections with every angle of rotation, will reach. 4. A base support for pole according to claim 3, ,o characterized in spherical surface sections that the located at the borders of the central boring of the mounting wall are developed to form a bowl being open fr towards the top and a ring ,Deing concentric and symmetric to I. the second rotation axis 6 0 A base support for pole according to claim 3 or 4, characterized in that the spherical supporting member -15 is arranged as a separate part in the head area of the anchor CI bolt D" 6. A base support for pole according to claim 1, characterized in that the power transmitting device is formed by a traction part at the' upper end of the anchor bolt 20 being angled by (EL between the two rotation axes oO and that the traction part extends through the central boring and is braced against the upper surface of the mounting wall 7. A base support for pole according to claim 6, characterized in that the traction part presents a male thread in the area of the central boring and above it, and is braced against the surface by a screw nut paralleling to the upper surface of the mounting wall 8. A base support for pole according to claim 7, -U an axial insert connection Deing dynamically balanced and 18 characterized in that the traction part is formed by an angled upper stretch of the anchor bolt itself. 9. A base support for pole according to one of the precedent claims, characterized in that an axial insert connection being dynamically balanced and concentric to the first rotation axis is also provided between the base wall of the base member and an anchor body 'being mounted C, in the foundation t 9q; C: 10. A base support substantially as hereinbefore described with reference to the accompanying drawings. eo Dated this 27th day of August 1986 O JEAN-JACQUES BOLLMANN By his Patent Attorney S GRIFFITH HASSEL FRAZER C C Cg is a vertical section through a further embodiment of the invention showing a special development of the spherical supporting member 0~ I I I *0so~ C 4qo* C p. e S p p. o~ e *000 S 00 4 0 ~*Q p.
