Locking washer for brace members
View Patent ↗Embodiments of the present disclosure provide an apparatus including a washer coupled to a strut, the strut including an interior channel, an opening formed through an end wall, and a set of turned-in ends, wherein the washer includes an engagement surface having a set of protrusions for engaging a surface of the strut. The apparatus further includes a fastener for securing the washer to the strut, the fastener having an opening for receiving support therein. In some embodiments, the protrusions are teeth that drive into the strut material when torqued, resulting in a mechanical connection with the strut and much higher slip resistance. Further, the washer is shaped to fit around an outside of the strut, thus adding additional stability and load capacity.

a washer coupled to a first side of a strut, the strut including an interior channel, an opening formed through an end wall, a set of turned-in ends, and an open side opposite the end wall, wherein the washer includes an engagement surface having a set of protrusions for engaging a surface of the strut;
a second washer coupled to a second side of the strut, opposite the first side of the strut; and
a support for securing the washer to the strut, the support extending through each of: the open side, the interior channel, and the opening formed through the end wall.
2. The assembly of claim 1 , wherein the washer has a clevis shaped body comprising:
a central section having a top surface;
an inner surface opposite the top surface, the inner surface in contact with the strut;
a curved engagement surface extending from the inner surface, wherein the set of protrusions is formed along the curved engagement surface; and
a free end extending from the curved engagement surface, the free end oriented substantially perpendicular to the central section.
3. The assembly of claim 1 , wherein the set of protrusions is a plurality of teeth extending from an inner surface of the washer.
4. The brace assembly of claim 3 , wherein the fastener has an opening for receiving the support therein.
5. The assembly of claim 1 , further comprising a strut fitting in abutment with a top surface of the washer.
6. The assembly of claim 5 , the strut fitting disposed between a fastener and the washer.
7. The assembly of claim 1 , further comprising a fastener for securing the washer to the strut, wherein the fastener has an opening for receiving the support therein.
8. The assembly of claim 1 , wherein the support is one of a threaded rod or a bolt.
9. The assembly of claim 1 , further comprising a strut nut engaged with the support and disposed within the interior channel.
10. The assembly of claim 1 , wherein the washer is directly coupled to one of: the end wall, and the set of turned-in ends.
11. A brace assembly comprising:
a washer secured to a strut, the strut including an interior channel, an opening through an end wall, an open side opposite the end wall, and a set of turned-in ends, wherein the washer includes an engagement surface having a set of protrusions for engaging a surface of the strut;
a support for securing the washer to the strut, the support extending through each of: the open side, the interior channel, and the opening formed through the end wall;
a strut fitting disposed between a fastener and a top surface of the washer.
12. The brace assembly of claim 11 , wherein the washer comprises:
a central section including the top surface, the top surface in contact with the fastener;
an inner surface opposite the top surface, the inner surface in contact with the strut;
a curved engagement surface extending from the inner surface, wherein the set of protrusions is formed along the curved engagement surface; and
a free end extending from the curved engagement surface, the free end oriented substantially perpendicular to the central section.
13. The brace assembly of claim 12 , wherein the set of protrusions includes a plurality of teeth extending from the curved engagement surface.
14. The brace assembly of claim 11 , further comprising a strut nut engaged with the support and disposed within the interior channel, wherein the strut nut includes a recess and a protrusion configured to receive the set of turned-in ends.
15. The brace assembly of claim 11 , further comprising a plurality of washers, wherein a first washer of the plurality of washers is coupled to a first side of the strut, and a second washer of the plurality of washers is coupled to a second side of the strut, opposite the first side of the strut.
16. The brace assembly of claim 11 , wherein the washer is directly coupled to one of: the end wall, and the set of turned-in ends.
17. A brace assembly comprising:
a washer secured to a strut, the strut including an interior channel, an opening formed through an end wall, an open side opposite the end wall, and a set of turned-in ends;
a fastener for securing the washer to the strut, the fastener having an opening for receiving a support therein, the support extending through each of: the open side, the interior channel, and the opening formed through the end wall, wherein the washer includes:
a central section having a top surface in contact with the fastener;
an inner surface opposite the top surface, the inner surface in contact with the strut;
a curved engagement surface extending from the inner surface, wherein a set of protrusions is formed along the curved engagement surface; and
a free end extending from the curved engagement surface, the free end oriented substantially perpendicular to the central section; and
a strut fitting disposed between the fastener and the top surface of the central section of the washer.
18. The assembly of claim 1 , wherein the second washer is secured to the strut by the support.
