Description
lloa7ss The present invention relates to an outwardly expansible xivet nut, made integrally of one piece, and for particular use on thin sheets.
There are different types of such rivet nuts now in use, for use on thin sheets, which are characterized by their methods of attachment to the sheets. There are some that can be secured from either side of the sheet while others can only be secured from one side. Among the latter are rivet nuts formed by a hollow body having a threaded part at one end.
Referred to as one-side connecting elements, they can be secured to the sheet from one side only and have, in addition to known advantages, also a number of drawbacks.
One of these is that they can exist only in a very narrow and positively restricted range of attachment. It is further known in the art that any such connecting elements which serve for connecting onto thin sheets is additionally used, apart from its main purpose which is that of creating a soli~ and reliable connection, to provide a bearing plate effect that reinforces the thin sheet around the hole through which the rivet nut extends. Known rivet nuts do not however appropriately meet this requirement as the size of the rivet head is substantially the same for thin or for thick sheets.
Known connecting elements wherein the part of the body lying between the head the the threaded part is divided longitudinally for affecting its integrity cannot be applied where a closed connection is required.
A primary object of the present invention lies in the provision of a rivet nut, for particular use with thin sheets, providing a substantial reinforcement of the connection because the closing head has a diameter which is much largex on the inaccessible side of the sheet.
Accordingly, the present invention as herein broadly ~i l~OU795 claimed is an outwardly expansible rivet nut of the a~ore-mentioned type, comprising: a hollow body of substantially constant outer diameter having a head at a front end to be applied over one face of a sheet, this body having an expansible part next to the head and a rigid part next to the expansible part and away from the head, these parts being adapted to extend through an opening in the sheet and away from the other face thereof so as to provide a one-side connection; wherein the expansible part of the body comprises a front section, next to the head, having a front bore of which at least a portion has a constant diameter and a central section having a central bore of a diameter smaller than the constant diameter of the front bore while the rigid part has an inwardly threaded bore adapted for the screwing of a member after the mem~er has extended through the front and middle bores, and a single circumferential groove into the body from the outer surface and located in the zone separating the expansible part and the rigid part.
Preferably, the front section extends along substantially 2/3 of the expansible part while the middle section extends along substantially the remaining 1/3 thereof.
Also, the groove may be about 1/2 of the thickness of the wall of the central section.
Preferably also, means are provided to afford axial reinforcement on at least part of the front section on its outer surface.
An advantage of a one-sided rivet nut with axial reinforcement is that of the combined effect of such axial reinforcement o~ the ~ront section having a thinner wall and of the annular groove on the outer surface of the body in the zone that separates the central section and the threaded part. It has been found that this effect provides a wide adaptability of the one-sided connection for use on sheets having different thicknesses, providing a high stress resistance of
There are different types of such rivet nuts now in use, for use on thin sheets, which are characterized by their methods of attachment to the sheets. There are some that can be secured from either side of the sheet while others can only be secured from one side. Among the latter are rivet nuts formed by a hollow body having a threaded part at one end.
Referred to as one-side connecting elements, they can be secured to the sheet from one side only and have, in addition to known advantages, also a number of drawbacks.
One of these is that they can exist only in a very narrow and positively restricted range of attachment. It is further known in the art that any such connecting elements which serve for connecting onto thin sheets is additionally used, apart from its main purpose which is that of creating a soli~ and reliable connection, to provide a bearing plate effect that reinforces the thin sheet around the hole through which the rivet nut extends. Known rivet nuts do not however appropriately meet this requirement as the size of the rivet head is substantially the same for thin or for thick sheets.
Known connecting elements wherein the part of the body lying between the head the the threaded part is divided longitudinally for affecting its integrity cannot be applied where a closed connection is required.
A primary object of the present invention lies in the provision of a rivet nut, for particular use with thin sheets, providing a substantial reinforcement of the connection because the closing head has a diameter which is much largex on the inaccessible side of the sheet.
Accordingly, the present invention as herein broadly ~i l~OU795 claimed is an outwardly expansible rivet nut of the a~ore-mentioned type, comprising: a hollow body of substantially constant outer diameter having a head at a front end to be applied over one face of a sheet, this body having an expansible part next to the head and a rigid part next to the expansible part and away from the head, these parts being adapted to extend through an opening in the sheet and away from the other face thereof so as to provide a one-side connection; wherein the expansible part of the body comprises a front section, next to the head, having a front bore of which at least a portion has a constant diameter and a central section having a central bore of a diameter smaller than the constant diameter of the front bore while the rigid part has an inwardly threaded bore adapted for the screwing of a member after the mem~er has extended through the front and middle bores, and a single circumferential groove into the body from the outer surface and located in the zone separating the expansible part and the rigid part.
Preferably, the front section extends along substantially 2/3 of the expansible part while the middle section extends along substantially the remaining 1/3 thereof.
Also, the groove may be about 1/2 of the thickness of the wall of the central section.
Preferably also, means are provided to afford axial reinforcement on at least part of the front section on its outer surface.
An advantage of a one-sided rivet nut with axial reinforcement is that of the combined effect of such axial reinforcement o~ the ~ront section having a thinner wall and of the annular groove on the outer surface of the body in the zone that separates the central section and the threaded part. It has been found that this effect provides a wide adaptability of the one-sided connection for use on sheets having different thicknesses, providing a high stress resistance of

the closing~head. Another notable advantage of the invention is that the closing head increases in size as the sheets get thinner and where such a greater reinforcement is desired. For thicker sheets, where the reinforcement effect of the closing head is not as acutely required, the diameter of the closing head may be smaller which, in turn, however gives an increased reslstivity to stress by pull and torsion.
Preferred embodiments of the invention will now be described with reference to the appended drawings whèrein:

Referring now to the drawings, there is shown a hollow inwardly threaded expansible rivet nut made according to the invention and particularly adapted for connecting onto thin sheets from one side thereof. This rivet nut comprises a hollow body having a generally constant outer diameter and formed of an expansible part 1 terminating at one end into a head 2 and integrally continuing, at the other end, into a solid non-expansible part 3 which has a threaded bore 4. The expansible part 1 of the hollow body is made up of a front section 5, bored as at 5a, and a central section 7, bored as at 7a, both bores being of uniform diameter and bore 5a being greater than bore 7a. The bore 5a preferably extends within 2/3 of the length of the expansible part 1 and the wall thickness of section 5 is relatively small while the bore 7a extends over about the remaining 1/3 of the length of part 1 and the thick-ness of the wall of middle section 7 is larger, this followingobviously from the fact that the outer diameter of the whole rivet nut is substantially constant, as aforesaid. Likewise, the diameter of the smaller bore 7a is preferably somewhat larger than that of the threaded bore 4 in order to enable a threaded member 10 (as in Figure 7) to be screwed thereinto after extendirlg through bores 5a and 7a.
The outer surface of the rivet nut is circular and provided, on the front section 5, with an axial reinforcement 9 which may be in the form of ribs pro-jecting from the outer surface of section 5, between the rivethead 2 and zone separating sections S and 7. These ribs are evenly distributed about section 5, as shown. In the embodiment

The outer surface of the rivet nut is circular and provided, on the front section 5, with an axial reinforcement 9 which may be in the form of ribs pro-jecting from the outer surface of section 5, between the rivethead 2 and zone separating sections S and 7. These ribs are evenly distributed about section 5, as shown. In the embodiment
4 -110~795 of Figures 5 and 6, the reinforcement 9 is in the form of inwardly pressed axially extending and peripherally evenly dis-tributed portions 8 of the wall o~ front section 5, leaving therebetween reinforcement ribs 9a. The reinforcement 9 may also be in the for~ of a polyhedron.
The outer surface of the rivet is provided, in the zone separating sections 7 and 3, with an annular circumferential groove 12 J the depth of which is about l/2 the thickness of the wall of section 7.
The manner of securing the one-sided rivet nut into an opening 13 of a thin sheet 14, as shown in Figures 7, 8 and 9, is obtained by screwing a threaded mandrel lO of an assembling tool, from the accessible side of the opening 13, until a pres-sure part ll is applied against the rivet head 2 thereby pres-sing the latter into the opening 13. By drawing member lO
toward the sheet 14 (see arrows in Fig. 8), a sudden deformation takes place in the transition zone between the bores 7 and 5 causing the expansible part l of the body to expand radially to take the shape of two frusto-cones facing one another along their large bases, as clearly shown in Figure 8. Further drawing of the member lO, always from the inaccessible side of the thin sheet 14, causes the thinner front section 5 to col-lapse, as shown in Figure 9, while the thicker central section 7 retains its conical shape and presses onto the collapsed section

With the aforesaid construction, it has been found that the diameter of the closing head 5 in the thin sheet 14 is substan-tially larger than that obtainable with rivet nuts of conventional construction with the effect that a substantial increase is obtained in the stress resistance to pull of the whole assembled part.
The manner of securing a one~sided rivet nut into an , 5 -s .
opening 13 made in a thicker sheet 15 is the same as securing it in a thin sheet 14, there being however a difference in diameter of the formed closing head, which diameter is smaller whereby the formed closing head shows a higher resistivity to pull stresses. One will easily gather, from Figures 9 and 10, the wide range of application of a one-sided rivet nut according to the invention.
