Suspension Hook

Abstract

The present invention encompasses an arrangement ( 1 ) related to a suspension hook with a discrete anchorage portion fixable via fixing means ( 3 ,( 3 )), to a vertically orientable support ( 2 ) and a discrete hook portion ( 5 ) coordinated with the anchorage portion. Said anchorage portion ( 4 ) displays an elongate surface section ( 4 a ) with barbs ( 6 ), while said hook portion ( 5 ) displays a short surface section ( 5 a ) with corresponding barbs ( 7,8 ) in order, in a position with the barbs cooperating, to cause the retention of said hook portion ( 5 ) against the anchorage portion ( 4 ) in one set position selectable from among a plurality of such positions. A vertically directed loading (‘F’) acting on the hook portion ( 5 ) is adapted to be absorbed by a cooperation between said barbs ( 8 ) allocated to the hook portion and barbs ( 6 ) allocated to the anchorage portion. Said surface section ( 5 a ) associated with the hook portion displays two series-oriented surface sections, a first surface section ( 8 ) structured with said barbs ( 7 ) and a superjacent, adjacent second surface section ( 9 ) which is structured planar. Said barbs ( 8 ) are disposed to be oriented adjacent and laterally oriented in relation to a lower plane (‘P’) allocated to the lower surface of the second surface section ( 9 ).

An arrangement, relating to a suspension hook, with an anchorage portion fixable via fixing means to a vertically orientable support and a hook portion or catch portion coordinated with the anchorage portion, said anchorage portion displaying an elongate surface section with barbs, while said hook portion displays a short surface section with corresponding barbs in order, in a position with the barbs cooperating, to cause retention of said hook portion against the anchorage portion in one set position among a plurality of selectable positions, where a vertically directed force or loading acting on the hook portion is adapted to be absorbed by said barbs allocated to the hook portion and barbs allocated to the anchorage portion, characterised in, that said surface section associated with the hook portion displays two series-oriented surface sections, a first surface section structured with said barbs and an adjacent second surface section which is slidably structured, such as planar, and that said barbs are disposed to be oriented adjacent and laterally adjacent a plane allocated to the second surface section. 
   
   
       2 . The arrangement as claimed in  claim 1 , characterised in that said surface section associated with the hook portion is adapted, with said first surface section, to merge into an integral short planar surface section which is however somewhat longer than said first surface section. 
   
   
       3 . The arrangement as claimed in  claim 2 , characterised in that the end portion of the planar surface section is oriented adjacent a spiculated hook portion or end portion allocated to the hook portion. 
   
   
       4 . The arrangement as claimed in  claim 1 , characterised in that said planar surface section is related to a thin tongue-like portion and is thereby resilient on an activating compressive force against the spiculated end portion of the hook portion. 
   
   
       5 . The arrangement as claimed in  claim 1 , characterised in that a rotation, caused by the activating compressive force, of the hook portion about an allocated axis of rotation against a resilient counterforce generated by the anchorage of the thin tongue-like portion in the hook portion is adaptable to release the barbed surface section of the hook portion from the barbed elongate surface section of the anchorage portion and thereby offer a simple displacement of the hook portion along the anchorage portion from a first selected adjusted position to another selected position.
