Raceway for instrumentation lines

摘要

A kit for forming a raceway assembly including a plurality of members can include a plurality of portions including channel portions and coupling portions, each of the portions extending in an axial direction and having a plurality of walls defining a generally U-shaped cross-section. Each channel portion may have at least one opening in at least one wall, and each of the coupling portions has at least one hole in at least one wall. Each coupling portion may be adapted to receive one or more of the channel portions so that axial directions of the received channel portions are aligned with the axial direction of the coupling portion and so that at least one of the openings of each received channel portion is aligned with at least one of the holes. The coupling portions and channel portions may have inter-engageable features which preclude movement of the received channel portions relative to the coupling portion other than in the axial directions thereof. In addition, the kit may include one or more non-threaded pins configured to pass through the aligned holes and openings and lock in place.

1. A kit for forming a raceway assembly comprising:
a plurality of members defining a plurality of portions including channel portions and coupling portions, each of the portions extending in an axial direction and having a plurality of walls defining a generally U-shaped cross-section, each said coupling portion having a bottom wall and first and second opposing sidewalls extending upwardly from the bottom wall, and each said channel portion having a base wall and a pair of lateral sidewalls extending upwardly from the base wall, the bottom wall of each said coupling portion having a plurality of holes at first intervals extending along a line in the axial direction, and the base wall of each said channel portion having a plurality of corresponding openings at the first intervals extending along a corresponding line in the axial direction, wherein each said coupling portion is adapted to receive one or more of the channel portions so that axial directions of the received channel portions are aligned with the axial direction of the coupling portion and so that a plurality of the openings of each received channel portion is aligned with a plurality of the holes, the coupling portions and channel portions having inter-engageable features which preclude movement of the received channel portions relative to the coupling portion other than in the axial directions thereof, the inter-engageable features comprising first and second lips formed integrally with the first and second sidewalls, respectively, each lip projecting inwardly from such side wall and then projecting downwardly toward the bottom of the coupling portion and inwardly towards the side wall of the coupling portion opposite from such side wall, so that edges of the first and second lateral sidewalls of each received channel portion are engaged between the first and second sidewalls of the coupling portion and the lips projecting from such sidewalls;the members including at least one hinge member, the hinge member including first and second portions and a hinge, the hinge connecting the first and second portions; and
a plurality of non-threaded pins configured to pass through the aligned holes and openings and lock in place, each pin having a plunger slidably disposed within a bore of the pin, wherein when the plunger is in its inward position the pin can pass through the opening in the wall of the channel portion and the hole in the wall of the coupling portion, and when the plunger is in its outward position the pin is locked in place.
