Adjustable rigid corner guard
View Patent ↗A rigid corner guard protects a corner of a structure from collisions with objects. The corner guard includes a rigid body having a base, an upper end, and a wall extending between the base and the upper end that is configured to surround the corner of the structure. The corner guard also includes a leg structure secured to the rigid body including at least two leg portions adapted to support the rigid body of the corner guard. The separation between the at least two leg portions is at a predetermined distance. The corner guard further includes an adjustment mechanism coupled to the rigid body. The adjustment mechanism is configured to apply a force to the rigid body to flex the rigid body to adjust the predetermined distance for installation of the at least two leg portions. The corner guard is constructed of material with sufficient strength and toughness to withstand collisions with heavier industrial type equipment.
1. A corner guard for protecting a corner of a structure from collision with objects, comprising:
a rigid body, comprising:
a wall having a base and an upper end;
wherein the wall extends between the base and the upper end, the wall having a front side facing away from the structure when installed and a back side facing toward the structure when installed;
A leg structure secured to the rigid body, the leg structure including at least two leg portions supporting the rigid body of the corner guard, the at least two leg portions separated by a predetermined distance and configured to extend below the base end of the rigid body for insertion into corresponding mounting holes; and
an adjustment mechanism coupled to the rigid body to forcibly hold the at least two leg portions at a desired distance other than the predetermined distance from each other;
wherein the adjustment mechanism applies:
a continuous tension force to the rigid body flexing the rigid body to decrease the predetermined distance of the at least two leg portions when the desired distance is less than the predetermined distance, and
a continuous compression force to the rigid body flexing the rigid body to increase the predetermined distance of the at least two leg portions when the desired distance is greater than the predetermined distance.
2. The corner guard of claim 1 , wherein the rigid body is formed of a material with a yield strength of greater than about 190 MPa.
3. The corner guard of claim 2 , wherein the rigid body is formed of a composite material.
4. The corner guard of claim 2 , wherein the rigid body is formed of a metal.
5. The corner guard of claim 2 , wherein the rigid body is formed of a material with a fracture toughness of greater than about 40 MPa-m 1/2 .
6. The corner guard of claim 1 , wherein the rigid body is formed of a stainless steel.
7. The corner guard of claim 1 , wherein the wall comprises a surface feature projecting outward from the front side of the wall.
8. The corner guard of claim 1 , wherein the leg structure is secured to the back side of the wall.
9. The corner guard of claim 1 , wherein the at least two leg portions are joined by the adjustment mechanism.
10. The corner guard of claim 1 , wherein the adjustment mechanism applies a force to the corner guard to flex the rigid body to adjust the predetermined distance by a distance of at least about 0.25 inches.
11. The corner guard of claim 1 , wherein the adjustment mechanism comprises:
a cylindrical portion with a first end, a second end, and a cylindrical axis extending through the center and along the length of the cylindrical portion, wherein the cylindrical portion is threaded in a first orientation at a first end and wherein the cylindrical portion is reverse threaded at a second end;
a first coupling that coupled with the threaded first end of the cylindrical portion to the rigid body; and
a second coupling that coupled with the threaded second end of the cylindrical portion to the rigid body;
wherein rotation of the cylindrical portion about the cylindrical axis in a first direction applies a force to flex the rigid body to reduce the predetermined distance, and wherein rotation of the cylindrical portion about the cylindrical axis in a second direction applies a force to flex the rigid body to increase the predetermined distance.
12. The corner guard of claim 1 , wherein the wall comprises a front right side face and a front left side face and wherein the front fight side face and the front left side face form an arcuate shape.
13. The corner guard of claim 1 , wherein the wall comprises a front right side face and a front left side face and wherein the front right side face and the front left side face meet in a rounded corner.
14. A corner guard for protecting a corner of a structure from collision with objects, comprising:
a rigid body having a base end, an upper end, and a wall extending therebetween, wherein the wall comprises a surface feature formed integrally with the wall, the surface feature projecting outward from a front side of the wall;
A leg structure secured to the rigid body, the leg structure including at least two leg portions supporting the rigid body, the at least two leg portions separated by a predetermined distance and configured to extend below the base end of the rigid body for insertion into corresponding mounting holes; and
an adjustment mechanism coupled to the rigid body to forcibly hold the at least two leg portions at a desired distance other than the predetermined distance from each other;
wherein the adjustment mechanism applies:
a continuous tension force to the rigid body flexing the rigid body to decrease the predetermined distance between the at least two leg portions for installation when the desired distance is less than the predetermined distance, and
a continuous compression force to the rigid body flexing the rigid body to increase the predetermined distance between the at least two leg portions for installation when the desired distance is greater than the predetermined distance.
15. The corner guard of claim 14 , wherein the rigid body is formed of a material with a yield strength of greater than about 190 MPa.
16. The corner guard of claim 14 , wherein the rigid body is formed of a material with a fracture toughness of greater than about 40 MPa-m 1/2 .
17. The corner guard of claim 14 , wherein the leg structure is secured to a back side of the wall.
18. The corner guard of claim 14 , wherein the at least two leg portions are joined by the adjustment mechanism.
19. The corner guard of claim 14 , wherein the rigid body and the adjustment mechanism adjust the predetermined distance from a front side of the wall.
