## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an apparatus and a method for mounting a component in a rack and, in particular, to an apparatus and a method for slidably mounting a component in a rack.
2. Description of the Related Art
In the interest of installation floor space economy, components of computer systems (e.g., central processing units, storage media drives, and the like) are often mounted in racks. Typically, such racks include vertically elongated, floor mounted cabinet assemblies of standard sizes that include a rectangular internal frame structure externally covered by removable panels and one or more horizontally pivotable access doors. It may be desirable from time to time for personnel to access these components to perform maintenance on and/or to reconfigure the components. Thus, such a component is typically mounted to the frame structure of the rack by slides so that the component may be readily moved between a forwardly extended component access position and a rearwardly retracted closed operating position.
To operatively mount the component in the rack, one portion of the slide is attached to the component enclosure and another portion of the slide is attached to the frame structure of the rack. These two portions are then mated such that they slidingly cooperate, thus allowing the component to be extended from and retracted into the rack. Typically, the component enclosure includes features, commonly referred to as “ears” or “flanges”, which have openings therethrough adapted to receive fasteners for securing the component to the frame structure of the rack. When the fasteners are received through these openings and engaged with corresponding openings in the frame structure of the rack, the component is inhibited from inadvertently being extended from the rack.
If the spatial relationship between the component enclosure and the frame structure of the rack is not accurately maintained, the openings in the component enclosure ears or flanges may not be aligned with the corresponding openings in the frame structure of the rack. Thus, it may not be possible for the fasteners to be placed through the openings in the component enclosure ears or flanges and engaged with the openings in the frame structure of the rack to secure the component enclosure to the frame structure. Further, it may not be possible to move the component to another location within the rack, which is often desirable, since the component being moved may physically interfere with one or more other components mounted within the rack.
The present invention is directed to overcoming, or at least reducing, the effects of one or more of the problems set forth above.

DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
FIGS. 1 and 2 partially illustrate an embodiment of a slide 100 according to the present invention. The slide 100 includes a fixed portion that is slidingly received within a guide 104 of a telescoping portion 106. The guide 104 allows the telescoping portion 106 to be moved inwardly and outwardly (indicted by the double-headed arrow 108) relative to the fixed portion 102 while inhibiting relative movement therebetween in other directions.
The telescoping portion 106 is attached to a component enclosure 110 by, for example, a plurality of screws 112. For ease of illustration and to avoid unnecessarily obscuring the instant invention, only one screw 112 is shown in FIG. 1 and the screws 112 are not depicted in FIG. 2. The plurality of screws 112 may be placed through a corresponding plurality of openings 114 (only one shown) defined by the telescoping portion 106 and threadedly engaged with a plurality of openings 116 (only one shown) defined by the enclosure 110. Alternatively, the telescoping portion 106 may be attached to the enclosure 110 by placing the screws 112 through the plurality of openings 114, 116, engaging nuts (not shown) with the screws 112, and tightening the nuts. The scope of the present invention, however, encompasses any way of attaching the telescoping portion 106 to the enclosure 110 known in the art.
Still referring to FIGS. 1 and 2, the fixed portion 102 comprises at least one rack-mounting ear 118 (two are shown in the illustrated embodiment) for attaching the fixed portion 102 to a rack 120. Each rack-mounting ear 114 defines an opening 122 therethrough, and the rack 120 defines a corresponding opening 124 therethrough. A screw 126 (not shown in FIG. 2) may be placed through the opening 122 through the rack-mounting ear 118 and threadedly engaged with the opening 124 through the rack 120 to attach the fixed portion 102 to the rack 120. Alternatively, the fixed portion 102 may be attached to the rack 120 by placing the screw 126 through the openings 122, 124, engaging a nut (not shown) with the screw 126, and tightening the nut. The invention is not so limited, however. The fixed portion 102 may be attached to the rack 120 by any way known in the art. While the rack 120 is illustrated as having a particular configuration, the scope of the present invention encompasses a rack having any configuration known in the art. Accordingly, the present invention includes any desired modifications to the rack-mounting ear 118 to accommodate various configurations of the rack 120.
The fixed portion 102 further includes a connecting ear 128 defining an opening 130 therethrough and the telescoping portion 106 includes a corresponding connecting ear 132 defining an opening 134 therethrough. The connecting ears 128, 132 may be joined by placing a screw 136 (not shown in FIG. 2) through the opening 130 and threadedly engaging the screw with the opening 134. Alternatively, the connecting ears 128, 132 may be joined by placing the screw 136 through the openings 130, 134, engaging a nut (not shown) with the screw 136, and tightening the nut. The scope of the present invention, however, includes any way of attaching the connecting ears 128, 132. Thus, when the connecting ears 128, 132 are joined, the telescoping portion 106 is inhibited from moving relative to the fixed portion 102 in the inward and outward directions (indicated by the double-headed arrow 108).
FIGS. 3–5 illustrate a system 300 wherein the enclosure 110 is mounted in the rack 120 with the slide 100. In addition to the attachments described previously, the fixed portion 102 also includes a rear ear 302 adapted to receive a screw 304 for attaching the fixed portion 102 to the rack 120. As in the other attachments, the screw 304 may be placed in an opening (not shown) through the rear ear 302 and threadedly engaged with the rack 120. Alternatively, the screw 304 may be placed through openings in the rear ear 302 and in the rack 120, a nut (not shown) engaged with the screw 304, and the nut tightened. The present invention is not so limited, however. The rear ear 302 may be attached to the rack 120 by any way known in the art. Thus, when the fixed portion 102 is slidingly received in the guide 104, the telescoping portion 106 is attached to the enclosure 110, the fixed portion 102 is attached to the rack 120, and the telescoping portion 106 is attached to the fixed portion 102 (i.e., the connecting ears 128, 132 are joined), a fixed relationship exists between the enclosure 110 and the rack 120.
Referring now to FIGS. 6 and 7, the enclosure 110 may be extended from the rack 120 by removing the screws 136 from the connecting ears 128, 132 and slidably moving the telescoping portion 106 (attached to the enclosure 110) relative to the fixed portion 102 (attached to the rack 120) in a direction corresponding to the arrow 602. By fully extending the enclosure 110 from the rack 120, devices (not shown) contained within the enclosure 110 may be replaced, added, or serviced. The enclosure 110 may be moved to a retracted, operational position by slidably moving the enclosure 110 relative to the rack 120 (as indicated by the arrow 604) and replacing the screw 136. Further, the enclosure 110 may be completely removed from the rack 120 and, if desired, replaced in a different vertical location within the rack 120, wherein the rack 120 is equipped with another fixed portion 102.
While FIGS. 1–7 illustrate an embodiment of the present invention in which the telescoping portion 106 comprises the guide 104, the invention is not so limited. FIG. 8 illustrates a slide 800 including a fixed portion 802 having a guide 804. A telescoping portion 806 is slidingly received within the guide 804. As is the previous embodiment, the guide 804 allows the telescoping portion 806 to be moved inwardly and outwardly relative to the fixed portion while inhibiting relative movement therebetween in other directions.
Still referring to FIG. 8, the telescoping portion 806 is attached to the component enclosure 110 by a plurality of screws 808 (only one shown), as described previously. The fixed portion 802 comprises at least one rack-mounting ear 810 (two are shown in the illustrated embodiment) defining an opening 810 for attaching the fixed portion 802 to a rack 120, as described relative to the embodiment illustrated in FIGS. 1–7. The fixed portion 802 further includes a connecting ear 814 defining an opening 816 therethrough and the telescoping portion 806 includes a corresponding connecting ear 818 defining an opening 820 therethrough. The connecting ears 814, 818 may be joined as described relative to the embodiment illustrated in FIGS. 1–7.
