Description
osc~
This invention relates to a securing device, which is specially applicable in the fastening of corrugated roofings.
. As is known, a corrugated roofing requires a series of hooks which are fixed to the beams on which the corrugated roofiAg is situated, the stems of the hooks ex-tending through : orifices made in the roofing itself 50 that they project above I the roofing. A washer made from materials of different hard-ness, normally steel and a skirt of lead or plastics material, ; is coupled to the projecting stem, which washer will subsequent-~1 lO ly be compressed by means of a nut which is screwed along the stem which pro~ects through the roofing. Deformation of the less hard part of the washer is achieved when the nut is screwed and tightened, thus sealing the orifice through which the stem of the hook passes. Thus, on the one hand fastening of the roofing is achieved, and on the other hand atmospheric agents such as water or wind are prevented from passing through the orifice.
In such means presently in use it is necessary to screw the nut along the stem of the hook until the nut contacts the washer which had previously been inserted by sliding it along the stem.
The present invention thus provides a securing device made from plastics material and comprising two members adapted to be coupled to each other, one said member comprising an ; inner body in the form of an internally screw-threaded hollow cylinder divided into a plurality of sectors and preferably three sectors each extendin~ over substantially 120 and separated hy preferably three cuts, flexible legs extending radially from substantially the mid-points of the respective sectors to an outer body concentric with the said inner body, ~ which Guter body is cylindrical internally and prismatic exter-i~, nally, and the second said member comprising an annular bushing .
` ~LGI~SC117~L
consisting of a cap portion having an axial orifice and a depending annular skirt, which skirt is adapted to be fitted into the space between the said concentric inner and outer bodies of the said one member so as to close in use the inter-nally screw-threaded member comprising the inner body of the said one memher around the screw--threaded stem of a hook pro-jecting through the inner body.
In order to avoid the loss of time involved in screw-j ing the nut along the stem as in the previously known securing ' 10 devices, in the present invention the washer made from two : materials each having a different hardness and the nut are ! replaced by a pair of the above members, both of which are madefrom plastics material, preferably nylon, which are to be coupled to each other, so that the one member can slide along the stem of the hook without being screwed to the stem until it contacts the roofing itself, at which position the second member is applied to force the one member to be adapted to the screw threads of the stem of the hook.
In one aspect thereof the present invention provides a securing device, particularly for sealingly attaching a corrugated roofing element to a threaded stem extending through an orifice in the roofing element, said device comprising: a first member including a central, cylindrical internally threaded-body divided into a plurality of separate cylindrical segments by a plurality of radial and longitudinal slots, each of said cylindrical segments having extending outwardly from a first axial end thereof a leg, the legs of said segments being cir-cumferentially spaced from each other, an outer body coaxially surrounding said central body, said outer body being joined at a first axial end thereof to said legs, said outer body having ~ a cylindrical inner surface and a polygonal outer surface, said ~i central and outer bodies defining therebetween an annular ....
7~
cylindrical channel open at second ends of said cylindrical segments and said outer body, said outer body having extending outwardly from said first end thereof a flexible annular skirt, said cylindrical segments, said legs, said outer body and said skirt being formed as an integral single member of a rigid plastic material; said first member being axially slidable without rotation over the threaded stem until said skirt con~
tacts a roofing element supported by the stem, said cylindrical segments being outwardly bendable at said legs during such sliding; and a second member including a cap-shaped element having extending therethrough an orifice to receive the threaded stem and having extending therefrom a cylindrical flange dimensioned to fit within and fill said annular channel, said flange when fitting within said channel forcing said cylindrical segments inwardly such that the internal threads thereo:E mesh with the threads of the stem, such that a wrench engaging said outer surface o~ said outer body can rotate said first member .~, about the stem and into tight and sealing contac-t with the ~,!
roofing element.
The invention will be further described, hy way of example only, with reference to -the accompanying drawings, in which:-Figure 1 is a half-sectioned elevational view of one of the members of a securing device according to the invention;
Figure 2 is an upper plan view of the member shown ~ in Figure l;

~ 5~7~4 undulation; and Figure 5 is a sectional view of the securing device when completely assembled and pressing against the undulation of the corrugated roofing.
The member shown in Figures :L and 2 comprises an inner body 1 in the form of an internally screw-threaded hollow ; cylinder which is divided into three sectors each extending J over substantially 120~ and separated by three GutS 2, 3 and 4.
j~ Flexible legs 5, 6 and 7 extend radially from substantially ! lo the mid-points of the respective sectors defined by the cuts ~ 2, 3 and 4 to the lower edge of an outer body 8 concentric with ; the inner body 1, the bod~ 8 being in the form of a nut, that is its inner surface being circular and its outer surface being prismatic (in the embodiment illus-trated hexagonal). Thus an annular channel 13 is formed between the inner body 1 and the outer body 8.
: i The body 8 is surrounded by an annular skirt 9 which is joined to the lower edge of the body 8 by a weak annular ~j;
zone 10.

This invention relates to a securing device, which is specially applicable in the fastening of corrugated roofings.
. As is known, a corrugated roofing requires a series of hooks which are fixed to the beams on which the corrugated roofiAg is situated, the stems of the hooks ex-tending through : orifices made in the roofing itself 50 that they project above I the roofing.

tacts a roofing element supported by the stem, said cylindrical segments being outwardly bendable at said legs during such sliding; and a second member including a cap-shaped element having extending therethrough an orifice to receive the threaded stem and having extending therefrom a cylindrical flange dimensioned to fit within and fill said annular channel, said flange when fitting within said channel forcing said cylindrical segments inwardly such that the internal threads thereo:E mesh with the threads of the stem, such that a wrench engaging said outer surface o~ said outer body can rotate said first member .~, about the stem and into tight and sealing contac-t with the ~,!
roofing element.
The invention will be further described, hy way of example only, with reference to -the accompanying drawings, in which:-Figure 1 is a half-sectioned elevational view of one of the members of a securing device according to the invention;
Figure 2 is an upper plan view of the member shown ~ in Figure l;
.~ Figure 3 is a half-sectioned elevational view of the second member of the securing device for co~operating with the member shown in Figures 1 and 2;
Figure 4 is a part-sectional view of an undulation of ~ a corrugated roofing and of ~he member as shown :in Figures 1 ;sr and 2 fitted around the stem of a hook pa,sed through the . ' 3-. :
~ 5~7~4 undulation; and Figure 5 is a sectional view of the securing device when completely assembled and pressing against the undulation of the corrugated roofing.
The member shown in Figures :L and 2 comprises an inner body 1 in the form of an internally screw-threaded hollow ; cylinder which is divided into three sectors each extending J over substantially 120~ and separated by three GutS 2, 3 and 4.
j~ Flexible legs 5, 6 and 7 extend radially from substantially ! lo the mid-points of the respective sectors defined by the cuts ~ 2, 3 and 4 to the lower edge of an outer body 8 concentric with ; the inner body 1, the bod~ 8 being in the form of a nut, that is its inner surface being circular and its outer surface being prismatic (in the embodiment illus-trated hexagonal). Thus an annular channel 13 is formed between the inner body 1 and the outer body 8.
: i The body 8 is surrounded by an annular skirt 9 which is joined to the lower edge of the body 8 by a weak annular ~j;
zone 10.
The lower part of the mernber shown in Figures 1 and
2 is concave and has a radius approximately equal to that of an undulation 12 (Figures 4 and 5) of a corrugated roofing to _ which the securing device is to be applied.
Referring to Figure 4 and supposing -that a stem 11 of a hook for fastening a corrugated roofing has been passed through an orifice previously made in a suitable location of , ~ .
~ an undulation 12 of the roofing, the member shown in Figures 1 .,, and 2 will then slide along a screw-threaded zone of the stem 11, this being possible due to the outward pivoting of ~he three sectors forming the body 1 of this mernber, as shown in '~ Figure 4. Thus, the member shown in Figures 1 and 2 functions as a tightening element which can slide downwards until it , ~,, .
sa 7~4 contacts the convex part of the undulation 12 of the roofing.
The complementary member shown in Figure 3, which is to be coupled to the member shown in Figures 1 and 2, comprises an annular bushing 14 of part-spherical form and consisting of a cap portion having a depending annular skirt 15, the latter being adapted to be inserted in the annular channel 13 of the member shown in Figures 1 and 2. It can be seen from Figure S
~ that the skirt 15 has a thickness which completely fills the .; annular channel 13, and consequently the internal screw thread !, lo of the body 1 is pressed against the external screw -thread of the stem 11. By applying for example a nut spanner -to the hexagonal body 8 the assembly of the two members is made to ` turn and thus -the skirt 9 of the body 1 is pressed against the ! undulation 12 of the roofing, which skirt 9 will give way slightly in view of the annular weakening zone 10 which joins it to the body 8.
Meanwhile, an annular lip 17 which defines an orifice 16 in the bushing 14, the orifice 16 having a smaller diameter - than the stem 11, will be deformed and pressed against the hollows formed by the screw thread of the stem 11, as illustrat-ed in Figure 5, whereby any possible penetration of rain water j is prevented.
t It will be understood that the method of securing corrugated roofing as described above may be very rapidly carried out.
