IPC: E04H12/22
Filed: 1996-08-22
Abstract: 1. Device for the vertical arrangement of a pole or post-like object (4) on a securing device (6) disposed at the ground end. comprising a substantially cylindrical, elongate mounting mandrel (10), extending upwards from free upper side of the securing device (6), which can be inserted into an accommodating bore (12) in the underside of the pole or post-like object (4) and further comprises a support plate (16) from whose plane the mounting mandrel (10) extends upwards and on which the underside (14) of the pole or post-like object (4) rests wherein at least one securing projection (18) protrudes upwards from the support plate (16) and penetrates the material of the pole or post-like object (4). characterized in that the mounting mandrel (10) is substantially thinner than the accommodating bore (12) in the underside of the pole or post-like object (4) such that there is considerable play between the outer surface of journal or mounting mandrel (10) and inner circular surface of the bore (12) surrounding the mandrel (10) in the underside of the pole or post 2. Device according to Claim 1, characterized in that a plurality of security projections (18) protrudes upwards from the support plate (16). 3. Device according to Claim 1, characterized in that at least one security projection (18) in the form of closed ring protrudes upwards from the support plate (16) 4. Device according to one of Claims 1-3, characterized in that at least one said security projection (18) on its upper free end is sharpened like a knife end. 5. Device according to Claim 4, characterized in that said sharpened end is arranged along the central longitudinal axis of the device (2). 6./ is tubular and sharpened like a knife end on its upper circular rim. 7. Device according to one of the preceding Claims, characterized in that the mounting mandrel (10) has near its upper end arranged substantially horizontal a through hole (30) through which a pin (36) is inserted, said pin having lesser size than the hole (30) wherein the pin (36) enters into the cross hole (38) made in the pole or post-like object (4) coaxially to the through hole (30) made in the mounting mandrel (10). 8. Device according to Claim 7, characterized in that the pin (36) has a thread screwing into the through hole (30) made in the mounting mandrel (10). 9. Device according to Claims 7 or 8, characterized in that the support plate (16) can be regulated vertically along the mounting mandrel (10). 10. Device according to Claim 9, characterized in that the support plate (16) rests on a foundation plate (34) which is associated with the outer surface of the mandrel via threaded connection. 11. Device according to Claim 1, characterized in that the mounting mandrel (10) is made of two concentric tubular sections (54, 56), wherein the outer tubular section (54) is vertically movablewith respect to the inner tubular section (56) and when outer tubular section (54) moves upwards, it essentially broadens radially in its upper part. 12. Device according to Claim 11, characterized in that the outer tubular section (54) has on its upper end a plurality of deformable petals (58), which, being moved upwards along the outer tubular section (54) are pushed against stationary support profiles of the inner tubular section (56) and essentially bent radially outward. 13. Device according to one of Claims 1-8, characterized in that the support plate (16) is made together with the securing device (6). 14. Device according to one of Claims 1-8, characterized in that the support plate (16) is an element, made separately from the securing device (6), enabling to be rigidly fixed to the underside of the pole or post-like object (4), forming line of force and/or geometrical locking with at least part of the outer surface of the mounting mandrel (10) when inserting the mandrel (10) into an accommodating bore (12) in the underside of the pole or post-like object (4). 15. Device according to Claim 14, characterized in that the support plate (16) has a central hole (22) which forms the line of force and/or geometrical locking with at least part of the outer surface of the mounting mandrel (10). 16. Device according to Claim 15, characterized in that said hole (22) is polygonal. 17. Device according to Claim 14, characterized in that said hole (22) is round. 18. Device according to any of Claims 14-17, characterized in that the internal diameter of the hole (22) is at least equal, or preferably less, than the outer diameter of the mounting mandrel (10). 19. Device according to any of Claims 14-18, characterized in that the hole (22) in the support plate is surrounded by a plurality of elastic teeth (28). 20. Device according to any of Claims 14-19, characterized in that the outer side surface of the mounting mandrel (10) is knurled (26), said knurling covers al least part of mandrel area.
