Claims
- 1. For securement to metal framing having a slot and inside and outside faces on opposite sides of the slot for attachment of parts to the framing through the slot from the outside of the slot, a fastener comprising:
- an elongate body having a first face constituting an inside face and an opposite face constituting an outside face, opposite sides, and opposite ends, the width of said body between said sides being less than the width of the slot in the framing whereby the body may be generally aligned with the slot, entered into the slot and passed through the slot from the outside to the inside of the framing and then turned to extend in crosswise pollution relative to the slot for engagement of portions of the outside face of the body adjacent the ends of the body with the inside face of the framing at opposite sides of the slot;
- a hole through the body extending from the outside to the inside face of the body for threadably receiving a bolt or the like;
- a recess in the inside face of the body;
- means for clamping the body in place in its said crosswise position comprising a clamp member carried by the body on the outside face of the body for engagement with the outside face of the framing on opposite sides of the slot when the body is generally aligned with, entered into, and passed through the slot and also when the body is turned to its said crosswise position, and retaining means for holding the clamp member in assembly with the body while permitting movement of the clamp member relative to the body between an extended position in which the clamp member is spaced away from the outside face of the body and a retracted position wherein the clamp member is more closely adjacent the outside face of the body, said retaining means comprising:
- guide members extending from the clamp member on opposite sides of the body having a length greater than the thickness of the body and projecting inwardly beyond the inside face of the body, at least one of said guide members having a portion bent to provide spring finger means engageable with the inside face of the body for providing spring action tending to draw the clamp member in the direction back toward the outside face of the body for clampwise engagement of the body and clamp member with portions of the framing on opposite sides of the slot, said spring finger means being receivable in said recess in the inside face of the body for holding the clamp member in assembly with the body; and
- a pair of retaining members extending from the clamp members on opposite sides of the body, said retaining members being engageable with the side of the body for preventing substantial rotational movement of the clamp member in at least one direction with respect to the body.
- 2. A fastener as set forth in claim 1 wherein said retaining members are located directly across from one another on opposite sides of the body for engagement with the body to prevent (a) substantial rotational movement of the clamp member in both directions with respect to the body and (b) substantial lateral movement of the clamp member relative to the body.
- 3. A fastener as set forth in claim 2 wherein said retaining members are located generally on the transverse centerline of the body.
- 4. A fastener as set forth in claim 3 wherein said clamp member comprises a ring having a radial flange extending outwardly therefrom for engaging the outside face of said framing, said guide members comprising a pair of arms extending from diametrically opposite portions of said flange.
- 5. A fastener as set forth in claim 4 wherein said retaining members are constituted by integral lugs extending from said ring.
- 6. A fastener as set forth in claim 5 wherein a pair of protuberances project laterally outwardly from opposite sides of the body at locations toward opposite ends of the body, said arms being engageable with said protuberances for assisting in the prevention of substantial rotational and longitudinal movement of the clamp member relative to the body.
- 7. A fastener as set forth in claim 6 wherein each arm is disposed immediately adjacent a respective protuberance on the side of the protuberance toward the transverse centerline of the body.
- 8. A fastener as set forth in claim 7 wherein said spring finger means comprises a finger bent from the inner end of each of said arms, said fingers being engageable with the inside face of the body and being adapted to flex as the clamp member is moved from its retracted toward its extended position.
- 9. A fastener as set forth in claim 8 wherein the inside face of the body has two recesses therein and wherein the inner ends of said fingers are bent to form finger tips receivable in said recesses.
- 10. As fastener as set forth in claim 9 wherein said fingers extend on opposite sides of said threaded hole through the body.
