referring generally to fig1 an exemplary electronic device 10 is illustrated according to one embodiment of the present invention . electronic device 10 may comprise , for example , a computer or a server having one or more removable components 12 and 14 . a typical example of a removable component 12 or 14 is a drive , such as a cd drive , floppy drive , hard drive or dvd drive . the removable components or drives 12 , 14 are accessible through a panel 16 , such as a front panel of electronic device 10 . device 10 also comprises at least one latch system 18 associated with at least one of the drives 12 or 14 . in the embodiment illustrated , both drives 12 and 14 have a corresponding latch system 18 . by actuating latch system 18 , the corresponding drive or other removable component is released and moved to an ejected position . for example , in fig1 drive 14 is illustrated in a latched or operating position , and drive 12 is illustrated in an ejected position that permits a user to easily grasp the drive and remove it from device 10 . the latch system 18 is designed to electrically and mechanically disconnect the associated drive as it is forced outwardly to the ejected position . this facilitates easy exchange or servicing of a desired drive . in the embodiment illustrated , the exemplary latch system 18 is actuated by pressing an actuator 19 . one example of actuator 19 is a pair of push buttons 20 and 22 . push button 22 extends through the front of push button 20 such that a user initially presses push button 22 inwardly until contacting push button 20 which is then moved inwardly an additional distance . depression of push button 22 mechanically releases the associated drive , and continued depression of push button 20 physically moves the drive to the ejected position . referring generally to fig2 and 3 , one specific embodiment of latch system 18 is illustrated . as illustrated best in fig2 latch system 18 is mounted to a chassis 24 of a desired electronic device , such as the computer or server discussed above . mounted in chassis 24 is a movable component , e . g . movable component 14 . in this particular embodiment , component 14 comprises a drive that is electrically coupled into electronic device 10 via a connector 26 that plugs into a corresponding connector 28 ( shown in dashed lines ) of device 10 when installed . movable component 14 comprises an outer housing 30 having a front 32 , a back 34 and a pair of sides 36 . latch system 18 is positioned along one of the sides 36 . this side 36 comprises a recessed or cutout portion 38 that interacts with latch system 18 to securely latch or hold component 14 when installed in electronic device 10 . latch system 18 generally comprises a throw or lever 40 , a base portion 42 , a latch 44 and a release plunger 46 ( see also fig3 ). when component 14 is installed , latch 44 engages recessed portion 38 to securely hold the component within chassis 24 . when latch system 18 is actuated , however , latch 44 is moved away from recessed portion 38 to release component 14 . subsequently , lever 40 is actuated against back 34 of component 14 to force the component outwardly to its ejected position . the lever acts against back 34 with sufficient force to disconnect connector 26 and to slide component 14 outwardly for servicing , replacement or exchange with another type of drive or other component . it should be noted that a variety of levers , buttons , and other actuators can be used to release component 14 and to move the component to an ejected position . as illustrated , though , release plunger 46 comprises push button 22 that extends through an opening 48 formed through the front of push button 22 . push button 22 forms a part of base portion 42 . to release and move component 14 to its ejected position , an individual presses push button 22 to move release plunger 46 against latch 44 . this movement causes latch 44 to disengage from recessed portion 38 , as indicated by arrow 50 of fig1 . as the user continues to depress push button 22 , push button 20 is eventually engaged causing movement of base portion 42 . for example , base portion 42 may be slidably mounted to chassis 24 via one or more pins 52 extending from chassis 24 and engaged within a slot 54 formed in base portion 42 . as base portion 42 is slid along pin 52 , it acts against lever 40 and pivots lever 40 about a pivot 56 . pivot 56 may be formed by an appropriate boss or screw extending through lever 40 into engagement with chassis 24 . lever 40 is positioned such that it is pivoted into back 34 of component 14 to force a disconnection of connector 26 and to move component 14 to its ejected position . thus , a user is able to actuate latch system 18 with a single linear motion , e . g . by applying pressure with a thumb or forefinger , to both release and eject a given component . as illustrated best in fig4 an exemplary lever 40 comprises a pivot arm 58 having an opening 60 therethrough for receiving pivot 56 . an abutment portion 62 is attached or formed at one end of pivot arm 58 . abutment portion 62 is designed to abuttingly engage base portion 42 when latch system 18 is actuated . at an end of pivot arm 58 generally opposite abutment portion 62 , a press plate 64 is positioned to engage back 34 of component 14 . thus , as force is applied to abutment portion 62 by base portion 42 , pivot arm 58 pivots about pivot 56 and drives press plate 64 against the back 34 of component 14 . when sufficient force is applied , connector 26 is disconnected and component 14 is moved to its ejected position . referring generally to fig5 one exemplary embodiment of both base portion 42 and latch 44 is illustrated . base portion 42 is designed generally as a plunger having a framework 66 extending between a press plate member 68 and push button 20 . framework 66 comprises a bottom plate 70 through which slot 54 is formed . bottom plate 70 also comprises a slotted region 72 for slidably receiving release plunger 46 . press plate member 68 is positioned to engage abutment portion 62 of lever 40 when push button 20 is pressed during actuation of latch system 18 . push button 20 , on the other hand , is a generally hollow structure having a plurality of side walls 74 and a lead wall 76 through which opening 48 is formed . push button 20 generally has a hollow interior 78 to receive release plunger 46 . latch 44 is mounted to framework 66 by a spring member 80 to permit flexible motion of latch 44 as represented generally by arrow 82 . latch member 44 further comprises a catch 84 designed for insertion into recessed portion 38 of component 14 . spring member 80 biases catch 84 towards this engaged position . thus , spring member 80 must be flexed against this bias to remove catch 84 when releasing and ejecting component 14 . to accomplish release of catch 84 , latch 44 further comprises a spur 86 that extends across the sliding path of travel of release plunger 46 . spur 86 also is coupled to spring member 80 and disposed at an appropriate angle or arc such that movement of release plunger 46 against a slide surface 88 of spur 86 causes sufficient flex of spring member 80 to withdraw catch 84 from recessed portion 38 . in the embodiment illustrated , spur 86 is positioned such that catch 84 is moved approximately twice the distance of the movement of release plunger 46 during release of component 14 . however , the desired angle and / or arc of spur 86 and the resultant movement of catch 84 may vary from one application of latch system 18 to another . referring generally to fig6 one exemplary embodiment of release plunger 46 is illustrated . in this embodiment , push button 22 is mounted to a framework 90 that includes a slide member 92 . slide member 92 is sized and positioned to extend upwardly through slotted region 72 of base portion 42 . additionally , the width of framework 90 may be selected for sliding receipt in a lower groove 94 of base portion 42 , as illustrated in fig5 . an engagement plate 96 extends from slide member 92 such that the engagement plate also protrudes upwardly through slotted region 72 of base portion 42 . engagement plate 96 is positioned to engage slide surface 88 of spur 86 during actuation of latch 44 and release of catch 84 . engagement plate 96 may comprise an angled lead surface 98 angled to engage slide surface 88 . additionally , engagement plate 96 may include a notched region 100 sized to slidably receive spur 86 therein . notched region 100 maintains spur 86 in a desired orientation during actuation . the various components are combined to provide an easy , tool - less release and ejection of component 14 . actuation of both the release mechanism and the ejection mechanism only requires that a user provide a force and motion in one direction . however , it should be noted that other designs may deviate from this single motion depending on the particular design of electronic device 10 and tool - less latch system 18 . it will be understood that the foregoing description is of exemplary embodiments of this invention , and that the invention is not limited to the specific forms shown . for example , the latch system may be incorporated into a variety of electronic devices for the removal of different types of components ; the latch system may be formed of various materials , including plastics and metals ; and the size , shape , location and orientation of various features and components of the latch system may be changed for a given application . these and other modifications may be made in the design and arrangement of the elements without departing from the scope of the invention as expressed in the appended claims .
