The present invention relates to a raceway for maintaining electrical and connectivity cables, and more particularly to such a raceway that can be adapted for use on or embedded into different floorings.
When considering connecting electrical and technology devices in an office, school, commercial or even a residential environment, there are situations when the connection needs to be made away from a wall or preexisting in-floor outlet or source. In such situations, it is desirable to manage the electrical and/or connectivity means in a track or raceway to limit tripping over the wires or cables, for aesthetics or concealment, for integration into the environment, etc.
Because the need for such connectivity has only grown due to our greater dependency on technology, including connections along such means as electrical wire, Ethernet cable, audio and/or video cable such as speaker wire, HDMI cable or the like, etc. (hereinafter “cable” or “cabling” broadly defined and including any electric, magnetic, optic or other connectivity transmission means), the need to manage such connectivity cabling is more important.
There exist basic devices for managing such cabling between a wall and a use site located away from a wall, or perhaps a floor receptacle, where fixed electrical and connectivity connections generally reside. However, such devices either work poorly on a plurality of different flooring materials, which may include floorings such as wood, tile, carpet, cement, rubber, cork, linoleum, etc., or are limited to a specific flooring environment.
For example, a basic floor cable cover may be a one-piece continuous structure, extruded of an elastomeric material having ramps on the two sides with a heightened channel running down the middle, which can be laid upon virtually any flooring. In another example, as shown in U.S. Pat. Nos. 6,566,598 and 6,844,493, which are directed to a raceway that is integrated with a floor covering.
What is needed in the art is a floor raceway that can be effectively used with a number of different floorings to accommodate current and later developed electrical and connectivity cabling, while providing safety and aesthetics to the environment.
The present invention is directed to a raceway that can be used with a variety of different floorings to provide connectivity, including power, communications signals, etc., between a location on the floor and a wall or other support element along one or more cables. The raceway is intended to provide such connectivity to a location within the environment where a need for power or communication ports exists, but where exposed cables create safety and/or aesthetic issues requiring management of the cables.
The raceway comprises an elongated track member, said track member comprising at least one elongated passage adapted to receive one or more cables, the at least one elongated passage located intermediate end channels on each side of the track member, a cover for enclosing the cables within the at least one elongated passage of the track member, and a channel member associated with each end channel, wherein the channel member is user determinable and at least a portion of the channel member resides in the end channel.
The preferred track member comprises more than one elongated passage for receiving cabling, with the individual passages defined by one or more internal walls that preferably assist in supporting a weight load on the cover. In a preferred embodiment, the internal wall defining passages comprises a pair of wall components with a wall gap therebetween for receiving a support post on an underside of the cover.
The end channels are preferably located along each of the outer side walls of the track member, the end channels being defined by the outer side walls and inner channel walls, the inner side walls also preferably including a terminal surface that supports a portion of the cover. The bottom surface of the track member is adapted to rest on the flooring itself, or on an underlayment or subflooring on which the flooring is installed.
The cover comprises a top surface and an underside, with extensions on the underside at or near the edges of the cover that cooperate with the channel members to locate and stabilize the cover on the track member. In a preferred embodiment, the extensions have enlarged distal ends to lock into receivers in the channel member within the end channels, described below, for providing an increased friction fit between the channel members and the end channels.
Internal walls of the track member preferably have a widened terminal surface upon which the underside of the cover rests to increase the weight load of the cover on the track member. When the track member includes internal walls having wall components with a wall gap therebetween, support posts are preferably included on the underside of the cover that align and cooperate with the wall gaps. The support posts can provide supporting, locating and/or stabilizing features to the cover on the track member, and/or can be used as a grounding/current-conducting interference blade to ensure the metal cover stays in the same electrical potential as the track member, which is preferably grounded at all times.
The top surface of the cover is bowed upward at least slightly from each side of the cover to the center of the cover to provide greater load capacity across the installed raceway.
The channel members are sized to fit within the end channels and preferably include cooperating elements between the channel members and the walls defining the end channels to retain the channel members in the end channels comprise channel member receivers for receiving. The cooperating elements can be any know fastener, adhesive, tape or the like, including detents, stops, catches, snaps, clips, screws, nails, or the like, preferably include one or more detents that engage an end of the channel member or a catch on a surface of the channel member, with the one or more detents associated with the outer side wall of the track member and/or an end channel wall.
Each channel member comprises a receiver with an opening for receiving the extension on the underside of the cover. In a preferred embodiment, the receiver is formed with flexible receiver walls that deform to allow the receiver to be compressed to fit within the cooperating elements of the end channel. Also preferred, the channel member does not fit snugly in the end channel upon insertion, to allow for tolerance in manufacturing and expansion for receiving the extensions of the cover. Once seated in the end channel, the extensions on the cover expand the receiver side walls outwardly and keep them from deforming inwardly, so that the cooperating elements retain the receiver in the end channels.
In a preferred embodiment, the receiver opening has a restricted entry and an expanded interior to cooperate with the enlarged distal end of the preferred extension. In this embodiment, the receiver walls deflect outwardly when the enlarged distal end of the extension passes through the restricted entry and return to a restricted orientation to engage the more narrow extension beyond the enlarged distal end. The full insertion of the enlarged distal end into the expanded interior of the receiver opening, with the restricted entry closing around the following portion of the enlarged distal end, assists in maintaining the cover on the track member.
A feature of the present invention is the ability of the user to select channel members according to the flooring on or in which the raceway is being installed. In this regard, interchangeable channel members preferably comprise a wing that is sized and configured for use with a particular flooring installation, where channel members with different wings are adapted to work with different floorings.
These may include a preferred truncated wing, which fits substantially within the outer dimension of the track member, for use in an environment where the height of the flooring material is substantially the same as that of the outer side wall of the track member. For example, the truncated wing can be used where the track member is placed on an underlayment and tiled in on both sides with tiles that are substantially the same height as the outer side wall.
A preferred transitional wing extends beyond the outer dimension of the track member, sloping downwardly from the outer side wall of the track member, which extends to a flooring material having a height greater than a bottom surface of the track member but less than substantially the height of the outer side wall of the track member. For example, the transitional wing can be used when the track member is placed on an underlayment and a short pile carpet, extending up only a portion of the outer side wall of the track member.
A preferred full wing extends beyond the outer dimension of the track member, sloping downwardly to engage a flooring material at substantially the same height as the bottom surface of the track member. For example, the full wing can be used when the track member is placed on flooring surface such as a wood or cement floor without being incorporated into the floor material, so that the wing can extend the entire height of the track member.
The wing may further include one or more struts and/or a base to assist in supporting the wing on the flooring and increasing the load capacity of the wing.
Of course, the channel member does not need to be the same on each side of the track member. For example, a channel member with a truncated wing can be used on one side of the track member against which a flooring of substantially the same height as the track member is installed, and a channel member with a full wing used on the other side where the flooring is even with the bottom surface of the track member.
The track member and/or cover can be formed of any suitable material, and are preferably formed of a rigid material that can be subjected to reasonable weight loads. The track member and/or cover are more preferably formed of a metal, a high density plastic or the like, and most preferably of aluminum. The channel member can also be formed of any suitable material, and is preferably formed of a plastic so that the receiver walls can be deformed slightly for insertion within cooperating elements on the channel walls and for receiving the enlarged distal end of the extension on the underside of the cover.
It is intended that the track member is fixed to the flooring, subflooring or underlayment by any know means, including by fasteners, such as screws, bolts, clips, snaps, clasps, nails, rivets or the like, preferably including associated holes or other structure or adapters on or associated with the track member to cooperate with the fastener selected, adhesives, sealants, tapes, and the like, including combinations thereof. Fasteners can also be used to further secure the cover on the track member, including through the use of self-tapping screws placed through the cover into the wall gap in the internal walls, to further ensure that the cover is not inadvertently removed from the raceway.
In the preferred embodiment, the track member, cover and channel members are sectioned with engagement elements between sections to extend the raceway to the desired length along a floor between a structural wall or support and the location on the floor. Additional elements, such as interior cable retainers fitted within the elongated passages, grounding clips, boxes that can be affixed along or at the end of a raceway to provide outlets or jacks of the cables, vertical connections at the wall or support, etc., are also contemplated.
The attached drawings are intended to better illustrate a preferred embodiment of the present invention without limiting the invention in any manner whatsoever.
