Abstract

A nut (10) for mounting into an opening (18) located in the central part of a panel (14) includes a sleeve (16) and resilient locking trips (44,46) and panel edge securing means 948) extending from opposite sides of the nut. When the nut is positioned within the opening (18) the locking strips (44,46) obstruct removal from the opening. On a bolt (62) being fully received within the sleeve (16) both the strips and edge securing means (48) contactingly engage the panel (14).

Claims

1. A nut for locking receipt within a panel opening formed from a sheetlike metal blank, comprising

a base plate;

a sleeve unitary with and upstanding from a major surface of the base plate;

first and second extensions integral with the baseplate and respectively extending away from each of two opposite sides of the base plate;

first and second spaced apart locking strips respectively integral with the first and second extensions and extending away from each of two opposite side edges of said extensions at an acute angle toward the sleeve central axis; and

first and second securing means unitarily located respectively to said first and second extensions between the first and second locking strips of each, each said securing means including a high-friction end portion facing generally away from the sleeve.

2. A nut as in claim 1, in which the high-friction end portions include more than one raised ridge.

3. A nut as in claim 2, in which the raised ridges are generally parallel to the panel opening inner edge.

4. A nut as in claim 2, in which the raised ridges extend across the panel opening inner edge at an angle other than 90 degrees.

5. A nut as in claim 1, in which the locking strips and securing means are so dimensioned that on mounting the same through a first side of the panel opening the locking strips contact the panel adjacent the second side of the panel opening throughout stress and unstressed use of said nut.

6. A fastener system for mounting an object to a panel opening solely from a first side of the panel, comprising:

a nut including,

a base plate having edges and dimensioned to prevent passage through the panel opening,

a sleeve on said base plate,

first and second extensions integral with the base plate and respectively extending away from each of two opposite edges of the base plate;

first and second locking means respectively extending outwardly from opposite sides of the

first and second extensions, said locking means having springlike characteristics and are of such dimensions as to be compressed while passing through the panel opening and after passing through the opening expand outwardly to obstructingly contact an opposite side of the panel,

first and second securing means of springlike characteristics respectively extending outwardly from the same two opposite sides of the base plate as the locking means, each such means having biting end portions; and

a bolt-like member received in the sleeve and having a head portion to affix the object to the nut and panel, at which time an end portion of the member contacts the securing means moving the biting end portions against opposite panel opening sidewall edges preventing relative transverse movement of the nut within the panel opening.

7. A fastener system as in claim 6, in which the boltlike member and sleeve form a clinch nut.

8. A fastener system as in claim 6, in which the sleeve and boltlike member are threaded.

9. A fastener system as in claim 6, in which the locking means are so-dimensioned that outer tips of said locking means are spaced from the base plate an amount sufficient to enable mounting of the fastener system to panels over a range of thickness.

10. A fastener system as in claim 8, in which the biting end portions extend generally parallel to the panel opening inner edge when the member is fully received within the sleeve.

11. A fastener system as in claim 6, in which the biting end portions include raised ridge portions that extend across the panel opening inner edge at an angle other than 90 degrees.
