The invention generally relates to improvements in the field of chases for routing utilities within a facility and methods of assembling and using the same.
Several publications are referenced in this application. The cited references are believed to describe the state of the art to which this invention pertains and are hereby incorporated by reference, particularly the systems and methods set forth in the detailed description and figures of each reference.
U.S. Pat. No. 7,075,005 to Drane describes purportedly known systems to run electrical wires and telecommunications wires underneath the surface of a floor. These cables and electrical systems may be placed under the floor surface so as to be more efficient in supplying power and data/telecommunication signals in commercial buildings. The electrical cables or wires beneath the floor may be accessed through a hole in the surface of the floor. In order to provide convenient access to the wires or cables as well as the termination devices which terminate the wires, a floor box is typically placed in the hole through the floor.
U.S. Pat. No. 3,061,663 describes purported improvements in under-floor duct systems for distributing electrical wiring to various locations within a building. Such systems generally comprise a network of junction boxes, ducts, or races for connecting the boxes, and conduit supporting means, all of which are embedded in the concrete floors of the building.
The invention relates generally to improved chase ways for utilities such as high and low voltage electric and methods of assembling the same. Specifically described is a duct assembly comprising an open top raceway with removable walkable top covers (when used in a floor based system), unlike known systems that are strictly floor embedded and cased into concrete. The open top allows repositioning of outlets, adding outlets and utilities without tearing up concrete. This is extremely important in today's flexible office spaces.
One aspect of the invention relates to a duct assembly comprising:
A plurality of tracks where each track includes a bottom side, opposed side walls separated by a central wall and an open top, where each wall includes a shelf support partway along the wall between the bottom side and the open top;
A plurality of joint bars received in channels formed in the bottom side of each track, such that a joint bar at least partially is received in channels of adjoining tracks, where the joint bars connect the adjoining tracks together;
A plurality of middle covers in at least some of the tracks supported by the shelf supports, where the middle covers include both solid middle covers and outlet middle covers having an opening sized to permit passage of utilities; and
A plurality of top covers including both top solid covers and top outlet covers, the top covers removably connected to a top of the tracks,
Where lower chases are defined by the bottom side of the tracks, the side walls, the central wall and the middle covers, and where upper chases are defined by the middle covers, the side walls, the central wall and the top covers.
The foregoing has outlined some of the aspects of the present invention. These aspects should be construed strictly as illustrative of some of the more prominent features and applications of the invention, rather than as limitations on the invention. Many other beneficial results can be obtained by modifying the embodiments within the scope of the invention. Accordingly, for other objects and a full understanding of the invention, refer to the summary of the invention, the detailed description describing the preferred embodiment in addition to the scope of the invention defined by the claims and the accompanying drawings. The unique features characteristic of this invention and operation will be understood more easily with the description and drawings. It is to be understood that the drawings are for illustration and description only and do not define the limits of the invention.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various example systems, methods, and so on that illustrate various example embodiments of aspects of the invention. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale. The illustrated embodiments are intended to illustrate, but not to limit the inventions. The drawings contain the following figures:
In the following description, for purposes of explanation, specific details are set forth in order to provide a thorough understanding of different aspects of the present invention. It will be evident, however, to one skilled in the art that the present invention as defined by the claims may include some or all of the features or embodiments herein described and may further include obvious modifications and equivalents of the features and concepts described herein.
As used herein, the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise.
Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect and “about” is utilized herein to represent an inherent degree of uncertainty that may be attributed to any quantitative comparison, value, measurement, or other representation. These terms are also utilized herein to represent the degree by which a quantitative representation may vary from a stated reference without resulting in a change in the basic function of the subject matter at issue. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. As used in the claims herein, the term “about” in claims refers to a +/−10% variation from the nominal value. It is to be understood that such a variation is always included in any given value provided herein, whether or not it is specifically referred to.
Terms used herein, such as “aspect” or “embodiment” or “exemplary” or “exemplified,” are not meant to show preference, but rather to explain that the aspect discussed thereafter is merely one example of the aspect presented.
Additionally, as used herein, relative terms, such as “substantially”, “generally”, “approximately”, and the like, are utilized herein to represent an inherent degree of uncertainty that may be attributed to any quantitative comparison, value, measurement, or other representation. These terms are also utilized herein to represent the degree by which a quantitative representation may vary from a stated reference without resulting in a change in the basic function of the subject matter at issue. As used in the claims herein, the term “substantially” in claims refers to a +/−10% variation from the nominal value. It is to be understood that such a variation is always included in any given value provided herein, whether or not it is specifically referred to.
The term “connected to” includes connected directly or indirectly and includes portions of items extruded, formed, shaped, stamped, or assembled into a unitary item.
As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur or the component might be omitted, and that the description includes instances where the event or circumstance occurs and instances where it does not or when the component is present or not present.
This system replaces dedicated in-floor systems made with pvc pipe and other types of electrical “chases.”
To move outlet locations with a traditional system you have to tear out the floor. The inventive system, we call it the EZ-Duct system, allows for fast and easy electrical updates, remodeling, and repurposing of industrial and office spaces. We believe it is preferable as a two level system. A lower level houses the cables. The device plates mount on the first shelf. The cables are sealed in the lower section with a flexible plastic cover. The space between the upper and lower section allows sufficient bend radius for most cable types. The egress points for the wires are easily moved along the top shelf and the foot traffic covers can be moved and cut to suit. All plates and covers are held secure by metal insert molded pivot nuts.
When sufficient tracks 104, 106 have been placed and/or encased, utilities may be placed in respective chases 110. Optionally, after the duct assembly 100, is installed and in use, utilities may be added or removed. Exemplary utilities include high and low power lines that may be desirably run in separate chases. Utilities can also include water lines, data cables, vacuum tubes, compressed air or other gas and pneumatic lines and the like. When utilities are in place, middle covers 142, 144 are placed in the chases and rested upon or snap fit onto shelf supports 120. Middle covers include solid middle covers 142 and outlet middle covers 144 but are not so limited. Outlet middle covers 144 in turn, can be single outlet, dual outlet or provided with other sized openings to allow access to one or more utilities in a lower portion of the chase and bring them into an upper portion at desired locations. Utilities may then be placed through the outlet middle covers roughly where desired. The ability to mount devices on the middle shelf formed by the middle covers 144, provides extra security and protection for sensitive connections like Ethernet or coax outlets. When components are in place, top covers 152, 154 may be installed to cover the open top 116. Top covers include top solid covers 152 and top outlet covers 154 but are not so limited. Top outlet covers 154 in turn, can be single outlet, dual outlet or provided with other sized openings. Significantly, the top covers 152, 154 need not align with the middle covers 142, 144 as the utility may travel in the upper portion of the chase defined by the middle covers to the point where the top covers 152, 154 are placed. Outlets or other utility access points may then be connected to the utility to allow use by a user. Additionally, new utility services may be added at later times. For example, top covers and/or middle covers may be removed to permit access. Also, utilities may be inserted and pulled through.
As may be appreciated, a duct assembly 100 as described, may be located in a floor, wall or overhead partition. Moreover, the duct assembly 100 as described allows easy installation of additional wires or other utilities by traditional pulling or cover(s) removal or combination thereof. As noted, the assembly 100 provides flexibility. For example, egress and device outlet points can be moved to any location. They are not required to be directly above each other.
