Hinged clamp bracket
View Patent ↗A clam-shell bracket for defining a mounting flange on a structural member, such as a hydroformed vehicle cross-member or frame rail, includes a lower body featuring an integrated locating feature with which to preposition the bracket on the structural member, and permanently-attached male threaded fasteners with which to thereafter secure the bracket to the structural member. The bracket further includes a hinged upper body having slotted bolt holes through which the lower body's fasteners may freely pass as the upper body is pivoted into the assembled position, thereby reducing the time required for bracket installation. The use of fasteners on the both the hinged end and opposite end of the lower clamp body provides an improved clamping force about the structural member, while the improved clamping force cooperates with the mating locating features of the bracket and the structural member to improve the lateral applied load transfer therebetween.
1. A hinged clamp bracket for a structural member, comprising:
a lower clamp body having a hinge end and a second end generally opposite to the hinge end;
an upper clamp body having a hinge end and a second end generally opposite to the hinge end, the hinge end of the upper clamp body being pivotally coupled to the hinge end of the lower clamp body for relative rotation about a hinge axis;
a first fastener adapted to secure the respective second ends of the upper and lower clamp bodies together, to thereby clamp the bracket about the structural member; and
a second fastener on the lower clamp body proximate to the hinge end of the lower clamp body, the first fastener being adapted to secure the hinge end of the lower clamp body to the hinge end of the upper clamp body,
wherein at least one of the lower clamp body and the upper clamp body includes a mating surface that is shaped to correspond and mate to a surface of the structural member; and
the mating surface defines a locating feature adapted to engage a complementary feature on the surface of the structural member.
2. The hinged clamp bracket of claim 1 , wherein the first end of the lower clamp body and the first end of the upper clamp body cooperate with a hinge pin to define a hinge.
3. The hinged clamp bracket of claim 1 , wherein the first fastener is a male threaded fastener permanently attached to the lower clamp body prior to clamping the bracket on the structural member.
4. The hinged clamp bracket of claim 3 , wherein the first fastener is a male threaded fastener selected from the group consisting of a weld stud, a staked bolt, and a clinched bolt.
5. The hinged clamp bracket of claim 3 , wherein the upper clamp body defines a first complementary slot adapted to receive the first fastener as the upper clamp body is pivoted about the hinge axis into an assembled position about the structural member.
6. The hinged clamp bracket of claim 1 , wherein the second fastener is a male threaded fastener permanently attached to the lower clamp body prior to clamping the bracket on the structural member.
7. The hinged clamp bracket of claim 6 , wherein the second fastener is a male threaded fastener selected from the group consisting of a weld stud, a staked bolt, and a clinched bolt.
8. The hinged clamp bracket of claim 6 , wherein the upper clamp body defines a first complementary slot adapted to receive the first fastener as the upper clamp body is pivoted about the hinge axis into an assembled position about the structural member.
9. The hinged clamp bracket of claim 1 , wherein one of the upper and lower clamp bodies defines an attachment point by which a component can be mounted on the structural member when the bracket is installed on the structural member.
10. The hinged clamp bracket of claim 9 , wherein the attachment point includes a pair of generally-parallel-spaced flanges, the flanges including aligned apertures defining a pivot axis for mounting the component.
11. The hinged clamp bracket of claim 9 , wherein the attachment point is defined on the second end of the lower clamp bracket.
12. The hinged clamp bracket of claim 1 , wherein the locating feature is a raised feature disposed on the mating surface of the lower clamp body intermediate the hinged and second ends of the lower clamp body.
13. The hinged clamp bracket of claim 1 , wherein the locating feature is a raised boss defined on the mating surface of the lower clamp body intermediate the hinged and second ends of the lower clamp body.
14. A hinged clamp bracket for defining an attachment point on a hydroformed structural member adapted to pivotally mount a component to the structural member, wherein the structural member includes a locating recess defined in a surface thereof, the bracket comprising:
a lower clamp body having a hinge end and a second end generally opposite to the hinge end, and an upper surface intermediate the hinged and second ends, the upper surface including a raised feature complementary to the locating recess of the structural member, the lower clamp body further including a pair of generally-parallel-spaced flanges, each flange including an aperture defining a pivot axis for mounting the component;
an upper clamp body having a hinge end and a second end generally opposite to the hinge end, the hinge end of the upper clamp body being pivotally coupled to the hinge end of the lower clamp body for relative rotation about a hinge axis;
a first fastener permanently attached to the lower clamp body proximate to the second end thereof for securing the respective second ends of the upper and lower clamp bodies together, to thereby clamp the bracket about the structural member; and
a second fastener permanently attached to the lower clamp body proximate to the hinge end thereof for securing the hinge end of the lower clamp body to the hinge end of the upper clamp body.
15. The bracket of claim 14 , wherein the first end of the lower clamp body and the first end of the upper clamp body cooperate with a hinge pin to define a hinge.
16. The bracket of claim 14 , wherein at least one of the first and second fastener is a male threaded fastener selected from the group consisting of a weld stud, a staked bolt, and a clinched bolt.
17. The bracket of claim 14 , wherein the upper clamp body defines first and second complementary slots respectively adapted to receive the first and second fasteners as the upper clamp body is pivoted about the hinge axis into an assembled position about the structural member.
18. The hinged clamp bracket of claim 14 , wherein the raised feature on the lower clamp body is a boss projecting from the upper surface of the lower clamp body, the boss being adapted to transfer loads to the structural member.
