Description




BACKGROUND OF THE INVENTION




The present invention relates to keyboard supports and the like, and in particular to an articulated keyboard support system having a tilt lockout that reduces the tilt range of a keyboard support, and a quick-disconnect connector that removably mounts the keyboard support to a mounting member.




Personal computers are becoming more common in many industry and office environments. Such systems may employ a keypad, mouse, and/or other data input devices, such as a digitizing pad. Often, the personal computer occupies much of the desk or worksurface, making it difficult to locate the keyboard thereon. Furthermore, many users do not prefer to locate the keyboard on the desktop because it is uncomfortable to address the keyboard over the course of the work day.




A number of devices have been developed to offer greater flexibility in supporting the keyboard, mouse, or other user interface devices at a comfortable position relative to the user. Many of these systems are structurally complex and typically require rather awkward adjustments through manipulations of a number of knobs and levers or handles. Moreover, many of the adjustable keyboard supports available today utilize an adjustment system which is counter-intuitive, such that the user must learn a detailed sequence of steps, knobs, locks, etc. before the device can be used effectively instead of simply moving the keyboard directly to the desired position.




Available keyboard support surfaces may incorporate a tilt adjustment device allowing the keyboard support surface to be adjusted over a range of tilt angles. The range of available tilt angles cannot be changed, such that the maximum and minimum allowable tilt angles are fixed. However, for some applications the entire range of tilt adjustability may not be needed or desired.




In addition, available keyboard support assemblies include a keyboard support surface that is permanently attached to a height adjustment device. Various keyboard support configurations have been developed and may include a hand support, a mouse support, or a specific keyboard clamping arrangement. In addition, the keyboard support surface may be configured for integration, with a specific worksurface, such as, for example, a corner worksurface. However, a keyboard support surface configured for a specific worksurface, such as a corner worksurface, may not be compatible with other types of worksurfaces. Accordingly, if a different keyboard support surface configuration is desired, the entire assembly, including the height adjustment device, must be replaced.




Accordingly, there was a need for a keyboard support with improved features which alleviated the above-identified problems.




SUMMARY OF THE INVENTION




One aspect of the present invention is to provide a keyboard support assembly for supporting computer keyboards and the like. The keyboard support assembly includes an articulating support arm having an end portion adapted to be secured to an associated base. The support arm also includes an opposite end portion. A keyboard support member is adapted to support a keyboard thereon. The keyboard support assembly further includes a threadless quick connector releasably connecting the keyboard support member to the articulating support arm adjacent the opposite end portion thereof.




Another aspect of the present invention is a keyboard support assembly for supporting keyboards and the like including an articulating support arm having an end portion adapted to be secured to an associated base. The support arm also includes an opposite end. A keyboard support member is adapted to support a keyboard thereon, and a first lock member is positioned on a selected one of the articulating support arm and the keyboard support member. A second lock member is movably mounted on the other of the articulating support arm and the keyboard support member. The second lock member is shiftable between a disengaged position and an engaged position wherein the second lock member engages the first lock member to secure the keyboard support member to the articulating support arm adjacent the opposite end.




Yet another aspect of the present invention is a keyboard support assembly for supporting keyboards. The keyboard support assembly includes an articulating support arm and a keyboard support platform adapted to support a keyboard thereon. The keyboard support assembly also includes a projection on a selected one of the articulating support arm and the keyboard support platform, the projecting defining a first engagement surface. A movable lock member is movably mounted on the other of the articulating support arm and the keyboard support platform. The lock member is shiftable between a released position and a locked position wherein the lock member engages the first engagement surface and secures the keyboard support platform to the articulating support arm.




These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT




For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG.


1


. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.




The reference numeral


1


(

FIG. 1

) generally designates an adjustable support for computer keyboards and the like


1


embodying the present invention. In the illustrated example, the adjustable support


1


includes a support member


2


shaped to retain an associated keyboard (not shown) thereon. The support member


2


is pivotally mounted, such as by a pin


3


, to shift about a normally, generally horizontal pivot axis


4


to define a tilt angle for the support member


2


and the keyboard with respect to a user. The tilt angle is adjustable within a predetermined tilt range. A tilt adjustment controller


5


is operatively connected with the support member


2


, and includes a tilt rod


6


and a releasable lock


7


which move relative to one another when the support member


2


is pivoted about the tilt axis


4


for adjustment of the tilt angle. The lock


7


engages the tilt rod


6


in a locked position to retain the support member


2


at a selected tilt angle. The lock


7


disengages the tilt rod


6


in an unlocked position to permit the support member


2


to pivot freely within the tilt range. A tilt stop


8


is positioned on the tilt rod


6


, and restricts movement between the tilt rod


6


and the lock


7


when the lock


7


is in the unlocked position to thereby reduce the tilt range of the support member


2


.




The adjustable support


1


includes a support arm assembly


10


and a keyboard support member


2


. A base


12


is configured to be secured to the lower surface of an associated worksurface (not shown). A mounting bracket


13


is fastened to the base


12


by fasteners such as screws


14


. Alternatively, the bracket


13


may be attached to a sliding track mount as illustrated in the embodiment of

FIG. 12

discussed below. An arm


15


comprises a first half


18


and a second half


19


(FIG.


1


). The arm


15


is rotatably mounted to the mounting bracket


13


at openings


17


by a second, or base pin


16


. A torsion spring


22


is connected to the mounting bracket


13


and the arm


15


, and biases the support member


2


upwardly to counteract the downward moment due to the weight of the support


2


and associated keyboard. The spring


22


fits within a drum or hub


23


formed at a base end


20


of the second half


19


of the arm


15


. A first end


25


of a flexible line such as cable


24


is connected to the mounting bracket


13


, and a second end


26


of the cable


24


is connected to the tilt rod


6


. The cable


24


includes several loops (not shown) around the hub or drum


23


such that when the cable


24


is tensed, the cable


24


frictionally engages the hub


23


, and prevents rotation of the arm


15


about a base pivot axis


11


at base pin


16


. When the cable


24


is slackened, the cable


24


does not frictionally engage the hub


23


, such that the height of the support member


2


may be adjusted by pivoting the arm


15


about the base pivot axis


11


.




An end portion


27


of cable


24


is slidably supported on a lower hub


28


of the second half


19


of the arm


15


. The weight of the associated keyboard and support member


2


acts downwardly, thereby generating a moment about the horizontal tilt axis


4


. However, because the end portion


27


of the cable


24


is spaced above the tilt axis


4


by the lower hub


28


, tension in the cable


24


generates a couple which prevents rotation about the tilt axis


4


.




A threaded portion


29


of the second end


26


of the cable


24


is connected to a threaded first end


30


of the tilt rod


6


. The tilt rod


6


is slidably mounted in a bracket or housing


35


. The bracket or housing


35


is formed from sheet metal, and includes lower openings


34


that pivotally connect the bracket or housing


35


to the arm


15


at the tilt axis


4


. A first bushing


37


is mounted in an opening


36


of end wall


69


of bracket or housing


35


, and a second bushing


38


is mounted in a second opening


39


(see also

FIG. 1C

) of an inner wall


77


that is spaced-apart, and parallel to end wall


69


. When the tilt rod


6


is installed through the bushings


37


and


38


, clips


40


are received on the grooved ends


41


of the tilt rod


6


such that the tilt rod


6


is slidably retained to the bracket or housing


35


. Tilt rod


6


is received in openings


46


in a pair of L-shaped lock plates


45


. Lock plates


45


are located between end wall


69


and inner wall


77


when assembled (

FIGS. 1C

,


1


D) in a manner similar to that of the embodiment illustrated in FIG.


14


. The upper end or edge


47


(

FIG. 1

) of each L-shaped lock plate


45


is received in a rectangular opening


50


in bracket or housing


35


(see also FIGS.


1


A and


1


B). A plastic fitting


59


having a generally downwardly opening U-shaped cross section within which the upper ends


47


of the lock plates


45


are pivotally received may be located in the rectangular opening


50


. A small coil spring


48


is located on the tilt rod


6


between the lock plates


45


(FIG.


1


). The spring


48


biases the lock plates


45


apart in the direction of the arrows “A”. The lock plates


45


pivot about the upper edges


47


such that the spring


48


causes the lock plates


45


to lock the tilt rod


6


in position due to the binding action between the tilt rod


6


and the openings


46


. In the locked position, the tilt rod


6


is prevented from moving relative to the lock


7


and bracket or housing


35


, such that the tilt angle of the support member


2


is fixed.




A lower housing


51


and cover member


52


are each made from a polymer material. The cover


52


includes protrusions


53


that are slidably received within channels


54


of lower housing


51


. The lower housing


51


includes a release lever


55


that is flexibly connected to the housing


51


at a base end


56


. The release lever


55


includes ribs


57


formed therealong, that are in close proximity to the lower portions or legs


49


of the lock plates


45


. To release the lock


7


, a user pushes upwardly on the end portion


58


of the release lever


55


with one or more fingers, causing the release lever


55


to flex upwardly. The lower portion


49


of each lock plate


45


is angled downwardly slightly, such that the lower edge


44


first contacts the ribs


57


. The lower housing


51


and ribs


57


are made from a polymer material having a relatively low coefficient of friction such that the contact of the ribs


57


with the edge


44


causes each lock plate


45


to slide along the ribs


57


in a direction opposite the arrows “A”, thereby causing the openings


46


of lock plates


45


to align with the tilt rod


6


, allowing the tilt rod


6


to slide freely such that the tilt angle can be adjusted.




The tilt stop


8


is preferably made of a flexible, polymeric material, and snaps over the end portion


42


of the tilt rod


6


. When the tilt stop


8


is installed onto the end


42


of tilt rod


6


, the end portion


66


of tilt stop


8


is directly proximate, or abutting the inner wall


67


of cover


52


, and the other end


68


of tilt stop


8


contacts the end wall


69


of the bracket or housing


35


. With further reference to

FIG. 3

, when the tilt stop


8


is placed on the end


42


of tilt rod


6


, the edge


70


of the cylindrical tab portions


71


is directly adjacent to, or contacting the clip


40


, such that the tilt rod


6


is prevented from sliding inwardly relative to the tilt stop


8


. In addition, the end


72


of the tilt rod


6


contacts the inner edge


73


of the tab


74


of the tilt stop


8


. Because the end


66


of stop


8


contacts the inner wall


67


of the cover


52


, the tilt rod


6


cannot slide outwardly. In addition, as described above, the tilt rod


6


cannot slide inwardly because the clip


40


abuts the edge


70


, while the end


68


abuts the end wall


69


of the bracket or housing


35


. Accordingly, with the tilt stop


8


installed onto the tilt rod


6


, the tilt rod


6


is prevented from moving, such that the tilt angle of the keyboard support member


2


cannot be adjusted. If desired for a particular application, the dimensions of tilt stop


8


may be chosen to limit the allowable range of tilt adjustment to a particular, smaller desired range without completely eliminating the range of tilt adjustment.




As best seen in

FIG. 3

, the tab


74


of tilt stop


8


has a relatively small base portion


75


. If desired for a particular application, the tab


74


can be manually broken off at


75


, such that the tilt rod


6


will not be prevented from traveling outwardly. Accordingly, with the tab


74


removed, the support member


2


may be tilted upwardly, with the maximum upward tilt being limited only by the engagement of the clip


40


at the inner end


76


of tilt rod


6


against the inner wall


77


of the bracket or housing


35


(FIG.


1


).




With the tilt stop


8


removed from the tilt rod


6


, the support member


2


may be adjusted across the entire, predetermined tilt range. The maximum downward, or positive, tilt occurs when the clip


40


located at the outer end


72


of tilt rod


6


contacts the end wall


69


of the bracket or housing


35


. The maximum upward, or negative, tilt angle occurs when the clip


40


located at the inner end


76


of the tilt rod


6


contacts the inner wall


77


of the bracket or housing


35


, as described above.




The support member


2


comprises a rear portion


60


and a forward portion


61


that are slidably interconnected by fasteners


62


. A pair of slots


59


in the forward portion


61


slidably interconnect the forward portion


61


and the rear portion


60


. A keyboard is placed between tabs


64


and hand support


63


, and rear portion


60


and forward portion


61


are moved together to clamp the keyboard between the tabs


64


and hand rest


63


. The fasteners


62


are then tightened to retain the keyboard. As described in more detail below, the support member


2


includes four adapters


90


that removably attach the support member


2


to the universal bracket or housing


35


.




The keyboard support member


2


is removably connected to the universal bracket or housing


35


of the support arm assembly


10


by a quick-disconnect connector assembly


80


. The quick-disconnect connector assembly


80


permits various types of keyboard support members to be interchangeably installed onto a support arm assembly


10


without the use of tools. As illustrated in

FIG. 2

, a second type of keyboard support


102


that includes a mouse support


103


may be interchangeably connected to the universal bracket or housing


35


of the support arm assembly


10


. The keyboard support of

FIG. 2

may be substantially the same as the support described in the above U.S. patent application Ser. No. 08/561,667, except that the support


102


illustrated in

FIG. 2

has been modified to include adapters


90


to permit quick attachment and detachment to the support arm assembly


10


. The quick-disconnect connector assembly


80


thereby allows a user to interchange various types of keyboard supports to reconfigure the support system to facilitate different users and tasks, without requiring that the entire adjustable support system be replaced.




As best seen in

FIG. 1D

, when the support member


2


is removed from the arm assembly


10


, and a clearance opening


9


is provided such that the tilt stop


8


may be removed from the tilt rod


6


. However, when the support member


2


is in the installed position the support arm assembly


10


, the tilt stop


8


is closed off, such that the tilt stop


8


cannot be removed.




With reference to

FIG. 1

, the quick-disconnect connector assembly


80


includes a polymeric slide plate


81


that is slidably mounted between the universal bracket or housing


35


and the lower housing


51


. The slide plate


81


is biased in the direction of the arrow “B” by a tension spring


82


which is interconnected between opening or connector


83


on the slide plate


81


and another opening or connector (not shown) on the inner wall


77


of the universal bracket or housing


35


. The universal bracket or housing


35


includes four tabs


84


, each having an opening


85


therein. Four generally U-shaped metal inserts


88


are closely received in pockets


86


of the slide plate


81


. Each pocket


86


has an opening


87


therethrough that aligns with an associated opening


85


in the universal bracket or housing


35


.




Each insert


88


fits into and around an annular groove


91


in an adapter


90


(

FIGS. 8

,


9


) when the slide plate


81


is in the fully forward, or locked position, in the direction of the arrow “B” of FIG.


1


. Each adapter


90


includes a pair of hexagonal outer portions


92


and a threaded opening


93


, such that the adapter can be threaded onto a stud


95


(

FIGS. 6

,


7


). Each stud


95


includes a shoulder


96


that retains the stud


95


to the keyboard support member


2


by press-fitting the stud


95


into a hole. With reference to

FIGS. 10 and 11

, each insert


88


is generally flat, forming a slot having a U-shape. Chamfered edge portions


105


facilitate engagement with the groove


91


of the adapter


90


. The radiused edge


106


fits closely around the groove


91


of the adapter


90


when the slide plate


81


is in the locked, forward position.




When the keyboard support member


2


is in the installed position on the bracket or housing


35


, each adapter


90


is received through an opening


85


in the bracket or housing


35


, and through the opening


87


in the pocket


86


of the slide plate


81


, and also through a clearance opening


89


in the lower housing


51


. The inserts


88


are shown above the bracket or housing


35


in

FIGS. 1 and 2

. However, when in the installed position, the inserts


88


are received within the pockets


86


of the slide plate


81


below a tab


84


of the bracket or housing


35


. The upper surface of slide plate


81


abuts the lower surfaces of tabs


84


, such that each insert


88


is retained within a pocket


86


. Tension spring


82


biases the slide plate


81


forwardly, such that each insert


88


closely engages the groove


91


of the adapter


90


, thereby securely retaining the support member


2


to the bracket or housing


35


.




To remove the support member


2


, a user grasps the downwardly extending flange or handle portion


97


of the slide plate


81


and moves the slide plate


81


rearwardly. This causes the inserts


88


to slide rearwardly, out of engagement with the groove


91


of the adapter


90


. With the slide plate


81


held in the rearward position, the support member


2


may be lifted upwardly to remove the adapters


90


from the universal bracket. To install the support member


2


, the slide plate


81


is slid to the rearward position, and the adapters


90


are aligned with the openings


85


,


86


and


89


, and inserted therethrough. Upon release of the slide plate


81


, the tension spring


82


will return the slide plate


81


to the forward position, thereby securely connecting the support member


2


to the bracket or housing


35


of the support arm assembly


10


.




The bracket or housing


35


includes a pair of center tabs


98


with openings


99


therein. The tabs


98


and openings


99


may be used to attach a keyboard support using conventional fasteners, such as screws (not shown), without use of adapters


90


, if desired for a given application.




The adjustable support


1


illustrated in

FIGS. 12-14

is substantially the same as the articulated keyboard shelf described in previously-referenced U.S. Pat. No. 5,836,560, entitled ARTICULATED KEYBOARD SHELF, filed on Nov. 22, 1995. This embodiment of the adjustable support has substantially the same support arm assembly


10


as the embodiments illustrated in

FIGS. 1 and 2

, except that the keyboard support illustrated in

FIG. 12

does not include a quick-disconnect connector assembly


80


, and the support member


112


is attached to the support arm assembly


10


in a relatively permanent manner by a lower support housing


113


and a pivot pin


114


.




The tilt stop


8


illustrated in

FIG. 12

comprises a tubular polymer member


118


, that may have a portion


119


(

FIG. 5

) removed so that the tilt stop


118


may be snapped over the tilt rod


6


. With reference to

FIG. 14

, the tilt rod


6


of this embodiment is slidably mounted in openings


121


and


122


of walls


119


and


120


, respectively. Flexing of the release lever


55


upwardly against the lock plates


45


will cause the lock plates to move together into the position illustrated in

FIG. 14

, such that the tilt rod


6


can slide inwardly or outwardly to adjust the tilt angle of the support


112


about pin


114


. With the tilt stop


118


installed adjacent the outer end


72


of the tilt rod


6


, the support member


112


cannot be moved downwardly to a positive tilt angle because the tilt stop


118


prevents the clip


40


at the outer end


72


from contacting the first wall


119


. However, if the tilt stop


118


is removed, the support


112


may be moved downwardly to a fully positive tilt angle. In addition, a second tilt stop


118


may be installed onto the tilt rod


6


adjacent the inner end


76


thereof, thereby preventing upward movement of support


112


to a negative tilt angle. If the inner end


76


of tilt rod


6


does not have a tilt stop


118


installed thereon, support


112


may be moved upwardly to a negative tilt angle until clip


40


at the inner end


76


of the tilt rod


6


contacts the second wall


120


. Accordingly, if a tilt stop


118


is snapped onto each end


72


,


76


of tilt rod


6


, the entire range of tilt adjustability can be eliminated. In addition, by selecting the length of the tilt stop


118


, and/or installing a tilt stop


118


at only one end of the tilt rod


6


, any desired limitation of the range of allowable tilt can be achieved.




A third embodiment of the tilt stop


8


is illustrated in FIG.


15


. The tilt stop


8


comprises a flat polymer member


128


having a cut-out portion


129


and a V-notch


130


. With reference to

FIGS. 16 and 17

, another type of adjustable support


135


may be mounted to the lower surface of an associated worksurface


134


. The adjustable support


135


illustrated in

FIGS. 16 and 17

is of a different type than those illustrated in

FIGS. 1

,


2


and


12


. A support surface


136


is configured to support a keyboard support platform. Arms


132


and


133


are pivotally connected to a base


131


. The support


136


includes at least one sidewall


137


extending downwardly directly adjacent a sidewall


138


. The tilt angle of support surface


136


does not change during height adjustment of the support surface


136


. A rod


139


has a threaded end (not shown) and a handle


140


at the other end. Rod


139


is closely received in a circular opening (not shown) in sidewall


137


, and also through an arcuate slot


141


in the sidewall


138


. If the tilt stop


128


is not installed, the rod


139


may travel along the arcuate slot


141


upon adjustment of the tilt angle of the support surface


136


. The handle


140


is then turned to lock the support surface


136


at the desired angle, such that the rod


139


cannot move along the arcuate slot


141


. To lock out, and prevent tilt adjustment of the support surface


136


, the tilt stop


128


is snapped over the rod


139


, and slid inwardly along the rod until the tilt stop


128


is received in the arcuate slot


141


. The outer contour of the tilt stop


128


closely matches the arcuate slot


141


, and the cut-out portion


129


closely matches the outer diameter of rod


139


, such that the rod


139


is substantially held in position, preventing tilt adjustment of the support surface


136


. If desired for a particular application, cut-out


129


may be offset, such that the support surface


136


is locked at a selected tilt angle. Alternatively, the dimensions of the tilt stop


128


could be adjusted, such that the tilt stop


128


slides within slot


141


with only a selected portion of the tilt adjustment range eliminated. In addition, tilt stop


128


may be manually broken apart at V-notch


130


to produce two halves. One half may then be installed to selectively permit only positive or negative tilt angles.
