DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a fastening member for fastening a protecting or shielding cover, in particular a tarpaulin, to a scaffolding or a similar supporting structure, and of the type comprising an anchor pin to be inserted through the cover from the surface of the cover facing the scaffolding, and a flexible strap of elastic material connected with the anchor pin and having a slit or opening in which the free end of the strap may be inserted, said strap having on part of its length a toothing or a similar contouring preventing the strap from being retracted after insertion through said slit or opening.
BACKGROUND DISCUSSION
Flexible straps for fastening a tarpaulin to a scaffolding, e.g. in connection with building work in winter, are known e.g. from DK-B-156 307.
In a strap of the above design disclosed in International Patent Application No. PCT/DK87/00155 (WO88/04368) the anchor pin is provided in that a piercing member at one end of the strap is designed as a harpoon-like squeezer to engage the external side of the tarpaulin, and the insertion slit or opening for the opposite free strap end is positioned immediately behind the piercing member so as to be positioned, after perforation of the tarpaulin by the harpoon-like squeezer engaging the external surface thereof, immediately inside the internal surface of the tarpaulin between the tarpaulin and the generally tubular frame structure to which the tarpaulin is to be fastened by the actual strap.
This impedes the mounting, since the free strap end has to be inserted in the slit or opening from the side of the frame structure facing the tarpaulin.
From DE-11-3204654 another design of a fastening member is known in which the anchor pin is connected by means of an elastic hinge joint with an intermediate member of U-shaped cross-section interconnecting two strap ends one of which is provided with elongate holes to engage with locking members projecting from the other strap end.
When mounting this fastening member the anchor pin must be manually turned from its normal position transverse to the strap on order to be passed through an eyelet in a tarpaulin and for establishment of the locking engagement between the elongate holes on one strap end and the locking members on the other both strap ends must be manipulated which makes the mounting a rather cumbersome operation when taken into account that normally a large number of fastening members are used for fastening a tarpaulin to a scaffolding.
The same disadvantage occurs with a still further design disclosed in DE-A-2326958 in which one free strap end forms a harpoonlike member with a number of local enlargements for engagement with key-hole shaped openings in the other strap end.
SUMMARY OF THE INVENTION
The present invention provides for considerably improving the ease of mounting, and is characterized in that said slit or opening is provided in a clamping member at the opposite end of the strap in relation to the insertion end, and in that the anchor pin is arranged substantially transverse thereof at a distance from said clamping member conforming to the dimensions of a member of the scaffolding or supporting structure while the distance of the anchor pin from the insertion end is substantially larger than said distance from the clamping member, the anchor pin being designed with two uniform parts positioned on either side of the strap, and connected with an intermediate member having opposite external and internal lateral surfaces which are firmly connected with the parts of the strap accommodating the clamping member and the free end of the strap, respectively, the intermediate member being further provided with an opening for retracting the free strap end to allow both parts of the strap to extend from the internal side of the intermediate member.
By the above design the clamping member with the insertion slit or opening will be positioned, after the tarpaulin has been pierced by means of the anchor pin engaging the external surface of the tarpaulin, at such a dist
