Abstract

A grommeted clamp assembly is provided for securing an elongated member to an underlying surface. The grommeted clamp assembly includes a grommet having a generally tubular body with an ovate cross section. An opening extends lengthwise along the body and is sized for receiving an elongated member. The grommet includes at least one transverse projection. The assembly includes a pair of clamp portions each having an anchoring end, an interlocking end, and a curved portion. A second anchoring end is configured for alignment with the first anchoring end. A second interlocking end is configured for being received by a slot of the first interlocking end. A second curved portion cooperates with a first curved portion to collectively support the grommet. At least one of the curved portions includes an elongated slot for receiving the at least one transverse projection for retaining the grommet.

Claims

1. A grommeted clamp assembly comprising:

a grommet having a generally tubular body with an ovate cross section, the body having a pair of flanges extending radially from opposing ends of the body with an opening extending lengthwise along the body, the opening sized for receiving an elongated member, the grommet having at least one transverse projection extending from a central portion of the body;

a first clamp portion having a first anchoring end for resting upon an underlying surface, a first interlocking end with a slot projecting therethrough, and a first curved portion formed between the first anchoring end and the first interlocking end; and

a second clamp portion having a second anchoring end configured for alignment with the first anchoring end, a second interlocking end configured for being received by the slot of the first interlocking end, and a second curved portion cooperating with the first curved portion to collectively support the grommet, wherein at least one of the first curved portion and the second curved portion includes an elongated slot for receiving the at least one transverse projection for retaining the grommet;

wherein each transverse projection further comprises a shaft with a distal head, each head having a diameter sized larger than a shaft diameter and smaller than an elongated slot width for retaining the grommet to each of the first clamp portion and the second clamp portion.

2. The assembly of claim 1 wherein the grommet further comprises an open molded grommet having a smooth cylindrical cavity and pair of opposing lead-in surfaces formed at the opening for engaging and securing the elongated member.

3. The assembly of claim 1 wherein the at least one transverse projection further comprises a pair of transverse projections that are oriented generally diametrically opposite one another when the grommet is in a closed position.

4. The assembly of claim 3 wherein each of the first curved portion and the second curved portion include the elongated slot for receiving one of the transverse projections, and wherein a width of each curved portion is sized for orientation between the pair of flanges.

5. The assembly of claim 1 wherein the first interlocking end further comprises a stepped slot having a lower slot width that is greater than an upper slot width.

6. The assembly of claim 5 wherein the second interlocking end further comprises a notched end having an outer width that is smaller than the lower slot width and greater than the upper slot width, such that the notched end is received by the lower slot width, and retained by the upper slot width.

7. The assembly of claim 1 wherein the first interlocking end further comprises an interlock aperture having a uniform width, the interlock aperture being sized for receiving the second interlocking end.

8. The assembly of claim 7 wherein the second interlocking end further comprises a pair of ears having a transverse orientation for insertion into the interlock aperture, the ears sized to extend beyond the uniform width when plastically deformed for locking the second clamp portion to the first clamp portion.

9. A method of securing an elongated member to an underlying surface with a grommeted clamp assembly, the method comprising:

forming a first clamp portion with a first anchoring end, a first curved portion and a first interlocking end, the first interlocking end having a slot with a lower slot width and an upper slot width and the first curved portion having a first elongated slot;

forming a second clamp portion with a second anchoring end, a second curved portion and a second interlocking end, the second interlocking end having a notched end with a distal outer width that is wider than an adjacent inner width, and the second curved portion having a second elongated slot;

forming a grommet having a generally tubular body with an ovate cross section, the body having a pair of flanges extending radially from opposing ends of the body with an opening extending lengthwise along the body, the opening sized for receiving an elongated member, the grommet having a pair of projections extending in opposing directions from the body;

inserting the notched end into the lower slot width of the first clamp portion;

rotating the notched end into the upper slot width of the first clamp portion, where the upper slot width is smaller than the lower slot width for connecting the clamp portions to each other;

inserting a first projection of the grommet into the first elongated slot;

inserting a second projection of the grommet into the second elongated slot;

wherein the grommet is configured to bias the notched end into the upper slot width for maintaining the connection of the second clamp portion to the first clamp portion; and

aligning the opening of the grommet between the first anchoring end and the second anchoring end.

10. The method of claim 9 further comprising:

engaging the elongated member at the opening of the grommet;

orienting the elongated member with a cavity of the grommet;

aligning the first anchoring end of the first clamp portion with the second anchoring end of the second clamp portion; and

securing the first anchoring end of the first clamp portion to the second anchoring end of the second clamp portion and mounting to an underlying surface.

11. A method of securing an elongated member to an underlying surface with a grommeted clamp assembly, the method comprising:

forming a first clamp portion with a first anchoring end, a first curved portion and a first interlocking end, the first interlocking end having a slot and the first curved portion having a first elongated slot;

forming a second clamp portion with a second anchoring end, a second curved portion and a second interlocking end, the second interlocking end having a notched end with a distal outer width that is wider than an adjacent inner width, and the second curved portion having a second elongated slot;

forming a grommet having a generally tubular body with an ovate cross section, the body having a pair of flanges extending radially from opposing ends of the body with an opening extending lengthwise along the body, the opening sized for receiving an elongated member, the grommet having a pair of projections extending in opposing directions from the body;

inserting the notched end into the slot;

inserting a first projection of the grommet into the first elongated slot;

inserting a second projection of the grommet into the second elongated slot;

aligning the opening of the grommet between the first anchoring end and the second anchoring end;

inserting the notched end into a lower slot width of the first clamp portion;

rotating the notched end into an upper slot width of the first clamp portion, where the upper slot width is smaller than the lower slot width for connecting the clamp portions to each other, wherein the grommet is configured to bias the notched end into the upper slot width for maintaining the connection of the second clamp portion to the first clamp portion;

engaging the elongated member at the opening of the grommet;

orienting the elongated member with a cavity of the grommet;

aligning the first anchoring end of the first clamp portion with the second anchoring end of the second clamp portion; and

securing the first anchoring end of the first clamp portion to the second anchoring end of the second clamp portion and mounting to an underlying surface.
