Traffic signal mounting bracket
A traffic signal mounting bracket for mounting a traffic signal on a post. The mounting bracket has a base, a cable, and a traffic signal attachment portion. The base is spaced apart from the post to maintain separation between the back of the base and the post. The cable is secured against rotation in a channel on the back of the base and extends rearwardly from the back of the base to loop around a post and is clamped between the front of the base and clamping blocks releasably attached thereto.
1. A traffic signal mounting bracket, for mounting a traffic signal to a post, comprising:
a base having opposed sides, a front, and a back;
a spacing flange on each side extending rearwardly from the back of the base and shaped to engage the post and maintain separation therebetween;
a retaining flange extending rearwardly from the back of the base adjacent to each spacing flange defining a channel therebetween having a channel width;
a first slot in the base aligned with each channel having a first slot width;
a clamping block releasably attached to the front of the base overlying each first slot, having a bearing surface and a second slot aligned with the first slot having a second slot width;
a cable having a bolt attached thereto at each end, the bolt having a head portion and a threaded portion, wherein the head portion has a width less than the channel width and greater than the second slot width, whereby the head portion is secured against rotation in the channel and secured against passage through the second slot and whereby the threaded portion extends through the first and second slots and is secured against the bearing surface by a fastener; and
a traffic signal attachment portion configured to engage with the front of the base and the traffic signal.
2. The traffic signal mounting bracket of claim 1 , wherein the front of the base and the clamping blocks each have complementary clamping grooves aligned with one another and shaped to receive and retain the cable therebetween.
3. The traffic signal mounting bracket of claim 1 , wherein each clamping block releasably attaches to the front of the base by a threaded post extending forwardly from the front of the base and by a threaded portion of the bolt on one end of the cable.
4. The traffic signal mounting bracket of claim 1 , wherein the bearing surface is a rounded recess and the threaded portion of the bolt is secured against the bearing surface by way of a pivot block shaped complementary to the rounded recess so as to pivot when seated therein.
5. The traffic signal mounting bracket of claim 1 , wherein the first slot width is larger than the width of the head portion of the bolt.
6. The traffic signal mounting bracket of claim 1 , wherein the base and the traffic signal attachment portion each have an electronics aperture therethrough and wherein the electronics apertures are aligned to permit the passage of electrical cables therethrough between the traffic signal and the post.
7. The traffic signal mounting bracket of claim 1 , wherein the cable extends between the clamping blocks.
8. The traffic signal mounting bracket of claim 1 , wherein the traffic signal attachment portion has two curved channels therethrough which each receive a mounting post extending forwardly from the front of the base to permit rotation of the traffic signal attachment portion relative to the base.
9. The traffic signal mounting bracket of claim 1 , wherein the base comprises a cylindrical extension extending forwardly from the front of the base.
