DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a fastening member for fastening an object such as a net, a steel wire, cable or the like to a carrier such as a post, a wall or the like, comprising a holder portion for fixedly retaining the object, and an anchorage portion for insertion in an opening in the carrier, the anchorage portion having barb members which are disposed, for securing the fastening member to the carrier, to snap into engagement with the carrier on insertion of the anchorage portion in the opening.
DESCRIPTION OF THE BACKGROUND ART
On erecting fences along traffic arteries to prevent game from getting on to the traffic artery, two methods are employed today for securing the fence. As one alternative, use is made of sheet metal lugs which extend about wires or cables included in the fence and which, via blind rivets, are secured in holes in those posts which support the fence. As another alternative, solutions are also proposed in the art in which the post supporting the fence is provided with welded projecting hooks on which the fence is suspended, whereafter the hooks are bent so as to form a closed ring which fixedly retains the fence.
These prior an designs and constructions may function satisfactorily of themselves, but are expensive to manufacture and use.
Fastening members of the type mentioned by way of introduction are also known within other technical fields, for example for fixedly securing different small fittings in the automotive industry or the like. However, these constructions cannot be employed for fastening the above-considered fences, on the one hand purely for reasons of mechanical strength, and on the other hand on the grounds that interconnection of a steel wire cable or the like included in the fence with the fastening member is not feasible.
SUMMARY OF THE INVENTION
The present invention has for its object to devise a fastening member of the type mentioned by way of introduction, the fastening member being designed in such a manner that it is readily suited for fastening objects, for example fences, to carriers, for example tubular posts, in such a way that the degree of mechanical strength will be satisfactory, that the erection operation may take place simply and conveniently and that there are no stringent demands placed on accurate tolerances in the components employed.
The present invention further has for its object to realise a fastening member which substantially cheapens erection work in comparison with the prior an technologies.
The objects forming the basis of the present invention will be attained if the fastening member intimated by way of introduction is characterized in that the anchorage portion has a longitudinal passage in communication with an accommodation space in the holder portion; and that the passage has a flared mouth portion at its end turned to face away from the accommodation space.
These characterizing features make for a highly simple assembly operation in that the fastening member is quite simply forced over a cable or steel wire include in the fence, and that thereafter the fastening member is forced into the opening in the carrier.
In one preferred embodiment, it suitably also applies according to the present invention that the accommodation space is of considerably greater extent transversely of the longitudinal direction of the passage than therealong.
These characterizing features allow for considerable flexibility when it comes to the possibilities of compensating for detective tolerances.
Further advantages will be attained according to the present invention if the subject matter hereof is also given one or more of the characterizing features as set forth in appended claims 3 to 9.
