Elements, couplers, systems, and methods for joining two or more trough members. A locking element for a coupler of a cable trough system includes a frame member including a shaft, a pawl member including first and second ends, and defining an aperture, the shaft of the frame member extending through the aperture so that the pawl member pivots on the shaft, and a member positioned to engage the first end of the pawl member to pivot the pawl member about the shaft into a locked position. When a force is applied to the first end in a direction opposite to that exerted by the member, the pawl member moves about the shaft into an unlocked position.

What is claimed is: 1. A coupler for a cable trough system, the coupler comprising: a body including a bottom wall and two side walls defining a trough, the body having a body terminal end defining an overlap region, the overlap region being sized to slideably receive a terminal end of a trough member along a longitudinal direction of the body; and a locking element couple to the body, the locking element including a frame member including a shaft, a pawl member including first and second ends, and defining an aperture, the shaft of the frame member extending through the aperture so that the pawl member pivots on the shaft, and a member positioned to engage the first end of the pawl member to pivot the pawl member about the shaft into a locked position to couple the body to the terminal end of the trough member; wherein, when a force is applied to the first end in a direction opposite to that exerted by the member, the pawl member moves about the shaft into an unlocked position. 2. The coupler of claim 1, wherein the frame member includes first and second frame members, and the shaft extends between the first and second frame members. 3. The coupler of claim 1, wherein the second end of the pawl member forms a point configured to engage a trough member that is inserted into the coupler. 4. The coupler of claim 1, wherein the member is a spring. 5. The coupler of claim 4, wherein the spring forms a general C-shape. 6. A cable trough system, comprising: a first trough member including a terminal end and an exterior surface; a coupler including a body having a body terminal end defining an overlap region, the overlap region being sized to slideably receive the terminal end of the trough member along a longitudinal direction of the body; and a locking element coupled to the body of the coupler, the locking element including: a frame member including a shaft; a pawl member including first and second ends, and defining an aperture, the shaft of the frame member extending through the aperture so that the pawl member pivots on the shaft; and a member positioned to engage the first end of the pawl member to pivot the pawl member about the shaft into a locked position to couple the body to the terminal end of the trough member; wherein, when a force is applied to the first end in a direction opposite to that exerted by the member, the pawl member moves about the shaft into an unlocked position. 7. The system of claim 6, wherein the frame member includes first and second frame members, and the shaft extends between the first and second frame members. 8. The system of claim 6, wherein the second end of the pawl member forms a point configured to engage the exterior surface of the trough member that is inserted into the coupler. 9. The system of claim 6, wherein the member is a spring. 10. The system of claim 9, wherein the spring forms a general C-shape. 11. A method for coupling a coupler to a trough member, the method comprising: allowing a spring member to move a pawl member about a shaft into a locked position; thereafter, inserting a trough member into the coupler; allowing a terminal end of the trough member to contact and slide along a point of the pawl member; when the trough member is fully inserted into the coupler, allowing the spring member to maintain the pawl member in the locked position so that the point of the pawl member engages an exterior surface of the trough member to lock the trough member in the coupler. 12. The method of claim 11, further comprising: applying a force to the pawl member to pivot the pawl member about the shaft against the spring member to an unlocked position wherein the point of the pawl member disengages the exterior surface of the trough member; and sliding the trough member out of the coupler. 13. The method of claim 11, further comprising positioning a frame member one the coupler, the frame member being coupled to the shaft. 14. The method of claim 11, wherein the spring member forms a general C-shape.
