FIELD OF THE INVENTIONThe present invention relates to a raceway assembly for instrumentation lines. More particularly, the present invention relates to a raceway assembly made up of channels and couplings connected by pins, which system can be assembled without tools.
BACKGROUND OF THE INVENTIONRaceways are used to route cables or other wires or instrumentation lines along surfaces such as walls, floors, ceilings, or on other fixed structures. Raceways provide a convenient way to eliminate the dangers associated with exposed lines and manage instrumentation lines while keeping the lines contained and often out of sight.
Many current raceway designs are made of multiple components, including straight channel sections connected by couplings. These components are connected together using a variety of methods including, for example, nuts and bolts and/or adhesives. While such methods may serve their intended purpose to connect the components of the raceway together, they often increase the cost, labor, and time of installing or removing raceway systems. This is because installation, removal, and repair of such systems often require the employment of tools such as wrenches or materials such as adhesive. This added burden may be excessive, particularly in large scale applications such as, for example, raceways for carrying instrumentation lines or cables at an oil refinery. In such applications, raceways may be difficult to access, and any down time of instrumentation while a raceway is being repaired may be extremely costly.
Accordingly, there is a need in the art for further improvements.
SUMMARY OF THE INVENTIONOne aspect of the present invention provides a kit for forming a raceway assembly including a plurality of members defining a plurality of portions including channel portions and coupling portions. Each the portions can extend in an axial direction and have a plurality of walls defining a generally U-shaped cross-section. Each said channel portion may have at least one opening in at least one wall. Each said coupling portion may have at least one hole in at least one wall. Each said 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. In addition, at least one of the openings of each received channel portion can be aligned with at least one of the holes. The coupling portions and channel portions can have inter-engageable features which preclude movement of the received channel portions relative to the coupling portion other than in the axial directions thereof. The kit can further include one or more non-threaded pins configured to pass through the aligned holes and openings and lock in place.
In a preferred embodiment, the walls of each said channel portion of the kit can include a base wall and a pair of lateral walls extending upwardly from the base wall. Each such lateral wall can have an upper edge remote from the bottom surface. The walls of each said coupling portion can include a bottom wall and a pair of side walls extending upwardly from the bottom wall, and each such side wall can have an upper edge and a lip projecting from such upper edge in an inward direction toward the other side wall of the coupling portion and downwardly toward the bottom wall of the coupling portion. Each coupling portion can be adapted to receive the one or more channel portions so that the edge of each lateral wall of each received channel portion is engaged between a side wall of the coupling portion and the lip projecting from such side wall.
Furthermore, the members may include at least one curved member curved in a direction transverse to the axial direction of the portion defined by the curved member. A member may include at least one hinge member, first and second portions, and a hinge connecting the first and second portions, wherein the first and second portions of the hinge member are coupling portions.
The pins of one embodiment of the invention may include a body having a head, a bore intersecting the body, and a plunger. The plunger may be slidably disposed within the bore and configured to oscillate between an inward position wherein the plunger is contained within the surface of the body and an outward position wherein the plunger extends beyond the surface of the body. Furthermore, 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. When the pin is in its outward position the pin is locked in place. Additionally, another embodiment may include a bracket adapted to attach one or more of the members to a structure.
Another aspect of the present invention provides a method for forming a raceway assembly. Such method can include providing a plurality of members defining a plurality of portions including a plurality of channel portions and a coupling portion. Each of the portions can extend in an axial direction and have a plurality of walls defining a generally U-shaped cross-section. Each said channel portion can have at least one opening in at least one wall. Each said coupling portion can have at least one hole in at least one wall.
The method can include receiving one or more of the channel portions by the coupling portion so that axial direction of each received channel portion is aligned with the axial direction of the coupling portion. At least one of the openings of each received channel portion can be aligned with at least one of the holes. The coupling portion and each received channel portion can have inter-engageable features which preclude movement of the received channel portion relative to the coupling portion other than in the axial directions thereof. The method can include passing one or more non-threaded pins through the aligned holes and openings to lock at least one received channel portion in place with the coupling portion.
In a preferred embodiment, the walls of each said channel portion can include a base wall and a pair of lateral walls extending upwardly from the base wall. Each such lateral wall can have an upper edge remote from the bottom surface. The walls of the coupling portion can include a bottom wall and a pair of side walls extending upwardly from the bottom wall. Each such side wall can have an upper edge and a lip projecting from such upper edge in an inward direction toward the other side wall of the coupling portion and downwardly toward the bottom wall of the coupling portion. The coupling portion can receive the one or more channel portions so that the edge of each lateral wall of each received channel portion is engaged between a side wall of the coupling portion and the lip projecting from such side wall.
