Abstract

An exemplary reinforcing element (104) may be configured to be received within a longitudinally extending cavity (C) defined by a structure (102). The reinforcing element may include a base portion (106) having a bonding material (108, 160) applied thereon, and a member (110, 150) selectively secured to the base portion and configured to selectively extend away from the base portion when the reinforcing element is received within the cavity. Accordingly, the reinforcing element may define a first length (L1) when the member is in a first position with respect to the base portion, and a second length (L1+L2) when the member is in a second position extending away from the base portion, the second length being greater than the first length. The selectively extending arrangement of the reinforcing element may generally allow improved ease and accuracy of installing the reinforcing element within a generally closed structure.

First claim

The invention claimed is:

1. A reinforcing element configured to be received within a longitudinally extending cavity defined by a structure, the reinforcing element comprising: a base portion having a bonding material applied thereon; and a member secured to and moveable with respect to the base portion, the member configured to selectively extend away from and be aligned in a longitudinal direction with the base portion when the reinforcing element is received within the cavity such that the reinforcing element defines a first length in the longitudinal direction when the member is in a first position with respect to the base portion, and a second length in the longitudinal direction when the member is in a second position extending away from and aligned in the longitudinal direction with the base portion, the second length being greater than the first length,
wherein the member includes an extrusion plate received within a central passage of the base portion, the extrusion plate configured to force an adhesive through the central passage, where said adhesive was pre-deposited in said central passage,
wherein the bonding material includes a structural adhesive, and
wherein the structural adhesive is non-expandable.

2. The reinforcing element according to claim 1 , further comprising a hinge securing the member to the base portion such that the member rotates about the base portion, wherein the hinge connects a first end of the member to an end of the base portion, such that the second length is approximately equal to a combined length of the member and the base portion.

3. The reinforcing element according to claim 2 , wherein the member is integrally formed with the hinge and the base portion.

4. The reinforcing element according to claim 1 , wherein at least one of the member and the base portion is formed of a plastic material.

5. The reinforcing element of according to claim 1 , wherein the member is selectively removable from the base portion.

6. The reinforcing element according to claim 1 , wherein the base portion includes at least one passageway extending through an outer wall of the base portion.

7. The reinforcing element according to claim 1 , wherein the base portion is formed of one of a plastic material and a metal material.

8. The reinforcing element according to claim 1 , wherein the base portion is extruded such that the base portion defines a predetermined cross-sectional profile along at least a portion of a length of the base portion.

9. The reinforcing element of one of the according to claim 1 , wherein the base portion defines a first length, the first length being between approximately 20 percent and 60 percent of a second length defined by the structure.

10. The reinforcing element according to claim 1 , further comprising the structure defining the cavity.

11. A method of making a reinforcing element configured to be received within a longitudinally extending cavity defined by a structure, the method comprising: providing a base portion having a bonding material applied thereon; and securing a member to the base portion in manner such that the member is moveable with respect to the base portion, the member configured to selectively extend away from and be aligned in a longitudinal direction with the base portion when the reinforcing element is received within the cavity such that the reinforcing element defines a first length in the longitudinal direction when the member is in a first position with respect to the base portion, and a second length in the longitudinal direction when the member is in a second position extending away from and be aligned in the longitudinal direction with the base portion, the second length being greater than the first length,
wherein the member includes an extrusion plate received within a central passage of the base portion, the extrusion plate configured to force an adhesive through the central passage, where said adhesive was pre-deposited in said central passage,
wherein the bonding material includes a structural adhesive, and
wherein the structural adhesive is non-expandable.

12. The method according to claim 11 , further comprising inserting the reinforcing element into the longitudinally extending cavity of the structure.
