Abstract
ABSTRACT OF THE DISCLOSURE
A fastener is disclosed which is adapted to be secured in a perforated member. The fastener comprises a grommet having a sleeve portion with an entry end and a set of fingers continuing from its other end; a plunger having an expander portion slidable through the sleeve portion to engage inwardly inclined surfaces on said fingers and expand the fingers, and a radially contractable ring of normally greater diameter than the inside of said sleeve and spaced from said expander portion a distance no greater than the distance from said entry end to said inclined surfaces and thereby being engageable with the sleeve portion prior to expansion of the fingers by the expander portion, whereby the friction between the sleeve and ring increases the total force required to spread the fingers.

Description
37~
The present invention is related to the disclosure shown in United States Patents 3,112,547 and 3,116,528 in which a grommet having a set of fingers which are expandable by an expander plunger thrust therein, the grommet resisting expansion until a preselected force is applied. For some uses an increased resistance to an expansion force is desirable; however, such increased resistance requires that the grommet be increased in size, requiring a corresponding increase in the size of the opening required.
The present invention overcomes this problem by providing a region axially displaced from the grommet fingers wherein a tubular port-ion of the grommet is engaged by a portion of the expander plunger cap- ~ -able of radial contraction to produce increased frictional force without altering those portions of the grommet and plunger which enter the grommet receiving opening.
According to the invention there is provided a fastener adapted to be secured in a perforated member, the fastener comprising:
a. a grommet having a sleeve portion with an entry end and a set of fingers continuing from its other end; -b. a plunger having an expander portion slidable through the sleeve port- -ion to engage inwardly inclined surfaces on said fingers and expand the fingers, and a radially contractable ring of normally greater diameter than the inside of said sleeve and spaced from said expander portion a distance no greater than the distance from said entry end to said inclined surfaces and thereby being engageable with the sleeve portion prior to expansion of the fingers by the expander portion, whereby the friction between the sleeve and ring increases the total force required to spread the fingers.

Figure 3 is a partially sectional, partially side view of the fastener shown in its expanded or secured position.
Pigure 4 is a transverse sectional view taken through 4-4 of Figure 1.
Figure 5 is an end view of one component of the fastener.
The fastener which embodies the plunger entry resistance means includes an expansible grommet 1 and an expander plunger 2.
The expansible grommet 1 is provided with a bore 3 and is prov-ided at one end with an external flange 4. Adjacent the flange is formed an external channel 5. Extending axially with respect to the channel 5 is a set of our fingers 6 separated by axially extending slots 7.
Adjacent the channel 5, the fingers 6 are provided internally with a retainer flange 8 interruped by the slots 7. The fingers are also provided at their extremities with an internal constriction 9 having a beveled inner or upper .

edge 10. The constriction 9 is also interrupted by the slots 7. Externally, the extremities of the fingers 6 are beveled as indicated by 11.
The expander plunger 2 includles a stem 12 dimen-sioned to pass through the bore 3. The extended end of the stem 12 is provided with an expander head 13 having shallow retainer channels 14.
The stem 12 is provided in spaced relation to the head 13 with an integral friction ring 15 having a trans-verse slot 16. The extended end of the friction ring is beveled as indicated by 17. The outer surface of the fric-tion ring is also beveled but to a much smaller degree than .
the beveled portion 17, the bevel or taper decreasing and reversing with increasing distance from the beveled portion 17. Beyo~d this end remote from the beveled portion 17, the expander plunger is provided with a shallow annular channel 18 which confronts a handle shoulder 19 forming a lower por-tion of the handle flan~.e 20 surrounding a shallow depressed end 21.
Except for the friction ring 15 and its relation to the bore 3, the expansible grommet l and expander plunger 2 may be considered as conventional components of a fastener.
One of the uses of a fastener of this type is to removably secure two panels 22 and 23 together as shown in Fig. 3. If it is desired that the fastener be permanently secured to panel 22, this panel is provided with a perfora-tion 24 which is slightly smaller than the diameter of the fingers 6. To support the grommet, the plunger is inserted partway, as indicated by dotted lines in Fig. l. The ~33~
grommet is then positioned over a perforation 24 and axial force is applied by the plunger 2 causing the fingers to re- .
strict sufficiently for the fingers to pass through the panels 22 as shown in Fig. 2. However, if the plunger is carelessly manipulated or the grommet is not properly aligned with the perforation, the expander head 13 of the plunger may snap passed the constriction or retainer flange 8 and engage the beveled inner edge 10 of the con- `
striction 9 causing the fingers to expand in the manner indicated in Fig. 3 so that the plunger and grommet are interlocked without the fingers entering the perforation 24.
If, however, the friction ring 15 is pxovided, sufficient resistance to movement of the plunger is pro-vided so that the expander head 13 does not spread the fingers 6 so that the grommet may first be forced through the panel 22.
Once the grommet 1 has been positioned in the panel 22, the fingers 6 may readily be inserted in the ;
perforation 25 of panel 23, as indicated in Fig. 2. When ~0 the two panels are in adjacent position as shown in Fig.
3, the friction ring 15 may be forced into the bore 3 and the expander head 13 forced between the constricted portions 9 of the fingers 6 locking the two panels together as shown in Fig. 3. When it is desired to disconnect the panels, an outward force applied to the plunger withdraws -the friction ring 15 from the bore 3 and the expander head 13 from the - :~
constriction 9 returning the pa.rts to the condition shown in Fig. 2.
Having fully described my invention, it is to be understood that I am not -to be limited to the details herein ~91!337~38 set forth, but that my invention is of the full scope of the appended claims.
