Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention pertains to the field of housings for electrical switches, such as button switches. More specifically, the housings hide and protect the buttons.




2. Discussion of the Related Art




New electronic systems devices, such as telecommunications servers, network servers, personal computers, and the like, derive from the efforts of planning and design teams. These teams are tasked with responsibilities that include adding new capabilities into existing systems, as well as building new products. Design and production schedules may be developed according to a strict timetable in an effort to get new products to market as soon as possible. It is frequently the case that new developments in electronic systems are rapidly overtaken and surpassed in an innovative marketplace.




As new products are being developed, future system enhancements may be planned for development and release that is scheduled to occur after the initial product release. Thereafter, the system may be sold with the enhancements intact, or a base model may be sold with an upgrade pathway for inclusion of the enhancements. The enhancements typically include hardware and related software.




An upgrade pathway may include, for example, adding additional busses or sockets for incorporating modular cards. The system housings may also, for example, be provided with switches or buttons that are needed for operator interaction according to planned improvements.




An array of nonfunctional buttons may be added to establish the upgrade pathway. These buttons are susceptible to damage or they may become fouled with debris before their use is actually required. It is desirable to provide a cover that protects such buttons, however, the cover must also permit free use of the buttons once the upgrade occurs. In order to avoid operator confusion as to the purpose of these nonfunctional buttons, it is also desirable that the cover hides the buttons from view until such time as an upgrade renders the buttons functional.




SUMMARY OF THE INVENTION




A button cover according to the principles described herein overcomes the problems described above and advances the art by providing a channel cover that prevents damage to the buttons, protects the buttons from debris, and/or hides the buttons from view until such time as the buttons are needed.




The channel cover according to the instrumentalities described herein comprises a central bight connected to a first leg and a second leg to define a recess therebetween. The first leg comprises a wall of transverse orientation with respect to the bight, and a lip protruding from the wall into the recess. The channel cover has sufficient flexion to permit expansion of the recess to accommodate the button when the lip passes over the button as the button is inserted into the recess. The channel cover may be used to cover a single button or, in an elongated configuration, it is capable of covering a plurality of the buttons when they are arranged in a row. The wall of the first leg preferably has sufficient length to prevent depression of the button when the channel cover is installed in the mating engagement over the button.




In especially preferred embodiments, the channel cover includes a nib protruding into the recess opposite the lip, and this nib engages complimentary structure on the button to secure the channel cover in place.




In still other embodiments, the lip comprises an upper face extending in parallel with the bight. The upper face may be formed of a raised rim that is set off a distance from the wall of the first leg.




The transverse orientation of the wall of the first leg does not have to be a right angle orientation and may, for example, comprise an oblique angle orientation between respective planar surfaces of the wall and the bight.




The aforementioned channel cover may be used according to a method comprising the steps of placing the lip into the complimentary female groove with the second leg resting atop the button, and pressing down on the channel cover to flex the channel cover as the channel cover expands to accommodate the button into the recess. The channel cover may thereafter be detached from the button by pulling straight up on the channel cover.




For example, a button or contact switch may be placed proximate a PCI bus to control delivery of electrical current to the bus. The button could be depressed if an operator desires either to insert or remove a card from the bus, in order that the task may be accomplished without having to power down the entire device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




There will now be shown by way of example and not by way of limitation, a channel cover according to the instrumentalities described herein comprising a central bight connected to a first leg and a second leg to define a recess therebetween. The first leg comprises a wall of transverse orientation with respect to the bight, and a lip protruding from the wall into the recess. The channel cover has sufficient flexion to permit expansion of the recess to accommodate the button when the lip passes over the button as the button is inserted into the recess. The channel cover may be used to cover a single button or, in an elongated configuration, it is capable of covering a plurality of the buttons when the plurality of buttons are arranged in a row. The wall of the first leg preferably has sufficient length to prevent depression of the button when the channel cover is installed in the mating engagement over the button.





FIG. 1

depicts a channel-shaped button cover


100


, i.e., a channel-cover, for use in covering nonfunctional buttons. The channel cover


100


is integrally formed in three main segments including a central bight


102


that preferably but optionally has an arcuate shape, a first leg


104


, and a second leg


106


. These segments


102


,


104


, and


106


combine to form a channel-shaped recess


108


. Channel cover


100


may be formed in any length including a length that is sufficient to cover a single button or a row of buttons.




The first and second legs


104


,


106


have a generally transverse orientation with respect to bight


102


, such that they intersect with bight


102


along edges


110


and


112


, but are generally perpendicular to wall


114


of bight


102


. This transverse orientation is only generally perpendicular in the sense that central wall


114


preferably but optionally forms an arched structure that may cause first leg


104


and/or second leg


106


to deviate inwardly from the perpendicular or true vertical by an angle β, which may, for example, range from 0° to 30 but is preferably less than 15° and most preferably about 5°.




The lower extremity of first leg


104


contains a lip


115


protruding into the recess


108


. Lip


115


preferably but optionally extends for the entire length of channel cover


100


, or lip


115


may only be formed in the precise location where it is useful for engaging complimentary structure on the buttons over which channel cover


100


will be placed in the intended environment of use. Lip


115


includes an upper face


116


that includes an upwardly pointing rim


118


, which is set off inwardly a distance from the inner face


119


of first leg


104


.




The lower margin of second leg


106


contains a semi-ovaloid nib


120


that protrudes into recess


108


opposite lip


115


.




Channel cover


100


is preferably made of a flexible material, such as a synthetic resin, that permits flexure of the first leg


104


over the range of angle β. This material is also preferably but optionally opaque and serves to hide the buttons that it covers.





FIG. 2

depicts a single button


200


that is mounted in a button housing


202


. Interior to the button housing and not shown in

FIG. 2

, are a conventional spring biasing button


200


into the position shown in

FIG. 2

, as well as a conventional electrical contact mechanism that makes electrical contact when button


200


is depressed against the spring bias in the direction of arrow


204


.




Button


200


comprises a neck


206


and a top plate


208


. The top plate


208


presents a greater surface area than does the top midsection of neck


206


. Top plate


208


includes a forward-facing chin


210


with a rounded face


212


. Chin


210


overhangs the button housing


202


to provide a forward-side recess or female groove


214


beneath the chin


210


. The forward-side recess


214


has sufficient dimensions for loose fitting male-female mating engagement with the lip


115


shown in FIG.


1


. Top plate


208


also includes a rearward overhang


216


, which provides a rearward recess


218


for complimentary engagement with the nib


120


on the second leg


106


of channel cover


100


shown in FIG.


1


.





FIG. 3

depicts the channel cover


100


during insertion over a row


300


of buttons


200


,


302


,


304


, and


306


. The buttons


302


,


304


, and


306


are identical to button


200


. Lip


115


has been inserted into the recesses


214


beneath the chins


210


(not shown in FIG.


3


), with nib


120


of the second leg


106


resting beneath overhang


216


of the respective buttons. Downward force exerted in the direction of arrow


308


causes outward expansion of the first and second legs


104


and


106


in the directions of arrow


310


as the nib


120


rides over the respective overhangs


216


and snaps into place.





FIG. 4

depicts the channel cover


100


fully attached after the insertion procedure shown in FIG.


3


. Nib


120


resides in rearward recess


216


beneath overhang


216


, and the lip


115


resides in the forward recess


214


beneath chin


210


. Lip


115


and nib


120


abut the button housing


202


and have sufficient vertical rise


400


to create a small gap


402


and prevent depression of button


200


in consequence of downward pressure


404


that may be applied to channel cover


100


.





FIG. 5

depicts the removal of channel cover


100


at such time as buttons, such as buttons


200


and


302


may be made function in consequence of a system upgrade. A pair of needle-nose pliers is used to grasp channel cover


100


on bight


102


. Upward lifting motion of the pliers


500


in the direction of arrow


502


causes outward flexion of the channel cover that permits removal. A snapping noise is heard as the channel cover is removed from each button. The channel cover may be cut, e.g., at position


504


, so that a portion of channel cover may remain in place over buttons that have not yet been made functional.
