Description




FIELD OF THE INVENTION




The present invention relates generally to attachment mechanisms, and more particularly, to a quick release latch for detaching a computer device from a secure attachment.




BACKGROUND OF THE INVENTION




Portable computer devices are now widely used by businesses and consumers. Such devices include notebook and laptop computers, tablet computers, Personal Digital Assistants (PDAs), and other types of communication devices. In addition, a full range of accessories are available to be used with these devices. Since these devices tend to be expensive, transportation and protection accessories, such as cases, covers, and leather portfolios have become very popular.




When a device is to be transported, a user can simply place the device into, for example, a leather portfolio accessory that protects the device against damage during transportation. Some portfolios allow the device to be operated while the device is still inside the portfolio. Thus, the user need not remove the device from the portfolio in order to use it.




Unfortunately, typical portfolios or carrying accessories are inconvenient and have several problems. For example, some portfolios do not attach securely to the device, so that the device is free to slide around within the portfolio. Other portfolios attach securely to the device; however, the securing mechanism interferes with the operation of the device. For example, the securing mechanism covers a portion of the display screen, obstructs buttons so that they cannot be actuated, or blocks access to input/output ports or access to internal devices, such as a CDROM device. One solution includes making the device bigger so that the attachment straps do not cover the screen or operational buttons, but having a bigger device may not be acceptable. Still other portfolios attach securely to the device, but it is difficult and time consuming to detach the device from them. As a result, if the user wishes to remove the device from the portfolio, it becomes a great inconvenience.




Therefore, it would be desirable to have an attachment mechanism that is suitable for use with carrying accessories of portable devices. The attachment mechanism should allow a portable device to be securely attached to the carrying accessory thereby preventing the device from sliding out of the closed case and falling to the floor as well as to keep the device from moving while being used. The attachment mechanism should also provide a way to quickly and easily detach the device from the carrying accessory.




SUMMARY OF THE INVENTION




The present invention includes a quick release latch mechanism that allows a user to securely attach, and quickly release, a portable device from a carrying accessory, such as a leather portfolio. Although described herein with reference to a specific portable device and carrying portfolio, one or more embodiments of a quick release latch included in the present invention are suitable for use in other types of applications where the secure attachment and quick release of a portable device is desired.




In one embodiment included in the present invention, a quick release latch mechanism is provided that securely attaches to a portable device without interfering with the user's ability to use the device. For example, the secure attachment does not obscure the display screen, interfere with the actuation of any buttons, or block access to any port or peripheral mounted on the device.




In one embodiment included in the present invention, a quick release latch mechanism is provided that includes a pivotless release handle. The release handle operates to quickly release the device from an attachment mechanism when the handle is moved in any direction (including rotation) within release plane of movement.




In one embodiment, a quick release latch for attaching and releasing a portable device from a secure attachment is provided. The latch comprises a spring-loaded attachment mechanism that can be detachably attached to a bottom surface of the portable device. The latch also comprises a release handle that is captured by the attachment mechanism, the release handle has profiled edges, and wherein movement of the release handle in any direction within a release plane causes the profiled edges to release the attachment mechanism from the portable device.




In one embodiment, a release handle is provided for use in a release mechanism for releasing a portable device from a secure attachment. The secure attachment comprises an attachment mechanism that has at least two attachment clips. The release handle comprises a first handle portion that is captured by the attachment mechanism. The first handle portion comprising profiled edges adjacent to the two attachment clips. The release handle also comprises a second handle portion that can be operated by a user, wherein the second handle portion extends from the first handle portion, and wherein movement of the second handle portion in any direction within a release plane of movement causes the first handle portion to spread the two attachment clips apart from each other to release the portable device from the secure attachment.

DETAILED DESCRIPTION




The present invention includes a quick release latch mechanism that allows a user to securely attach, and quickly release, a portable device from a carrying accessory, such as a leather portfolio. The quick release latch mechanism is suitable for use in virtually any application where secure attachment and quick release of a portable device is desired.





FIG. 1

shows one embodiment of a portfolio


100


for transporting a portable device


102


having a display screen


116


. The portfolio


100


includes a quick release latch mechanism constructed in accordance with the present invention.




The portfolio


100


may be constructed of leather, cardboard, plastic, fabric, or any other material. The portable device


102


may be a personal computer, PDA, tablet computer, or any other type of portable device. Typically, a tablet computer has dimensions of approximately 8″×10″×1″ and a weight of 1-7 pounds. In such an application, the portfolio would be sized to accommodate such a device. The device


102


is attached to the portfolio at an attachment plate


104


located at an interior portion of the portfolio. The attachment plate may be constructed of plastic, metal, cardboard, or any other suitable material. Once attached to the attachment plate


104


, the device


102


is secure for transporting. In this embodiment, the portfolio


100


includes a top portion


106


that is placed in an open position to install/remove or use the portable device


102


, and placed in a closed position to transport the portable device. When the top portion


106


is in the closed position, the portable device


102


is protected from damage during transportation.




In the closed position, a strap


106


is used to secure the top portion


106


so that it remains in the closed position during transportation of the device. The portfolio may also include one or more pockets or storage compartments


110


that can be used to store additional items, such as cables, user manuals, or for instance, a portable keyboard


112


.




The strap


108


may also be used to hold the portfolio in an upright position during operation. For example, the top portion


106


is folded in a reverse direction so as to form a support structure that is held in place by the strap


108


. This is shown in

FIG. 1

in the “operation” mode. The portable keyboard


112


is shown in front of the device and may interface to the device using a wired, wireless, or optical connection.




In the “attach/release” mode shown in

FIG. 1

, the portfolio


100


is shown lying open so that the device may be released from its secure attachment. A pivotless release handle


114


constructed in accordance with the present invention is used to release the device from the portfolio. The device may be removed for use and then reattached to the portfolio when its time to transport the device. The attachment mechanism attaches the portfolio to the back surface of the device so that there are no straps or other attachment features obstructing the device display, device buttons, or access to any device peripheral.





FIG. 2

shows a detailed view of the attachment plate


104


. The attachment plate includes a flat top surface


208


that contacts a bottom surface of the portable device. An attachment mechanism is mounted to a bottom surface


210


of the attachment plate


104


. As part of the attachment mechanism, alignment pins


202


pass through the attachment plate and are used to secure the attachment mechanism to the plate and align the plate


104


with the bottom surface of the portable device during installation. The alignment pins also help prevent excessive movement of the portable device when it is attached to the attachment plate. The attachment clips


204


also pass through the attachment plate and operate to clip onto corresponding clip receivers located at the bottom surface of the portable device. Thus, when the portable device is attached to the attachment plate


104


, the attachment clips


204


hold the device tightly and the alignment pins prevent any slipping or sliding movement of the device.




A portion of a quick release handle


206


is also shown in FIG.


2


. The handle


206


extends underneath the attachment plate so that it cannot be fully seen in FIG.


2


. The handle


206


is used to operate the attachment clips


204


in order to quickly release the portable device from the attachment plate. In one embodiment, the handle


206


operates to spread the attachment clips


204


apart from each other so that the attachment clips no longer engage the corresponding clip receivers on the portable device. Once the attachment clips


204


are disengaged from the clip receivers, the portable device may be removed from the attachment plate. A more detailed discussion of the operation of the attachment clips


204


and release handle


206


is provided in the following text.





FIG. 3

shows a detailed view of the bottom surface


210


of the attachment plate


104


. In this view, it is possible to see a complete view of the release handle


206


and a clip cover


302


. The release handle


206


includes a small opening (shown at


304


) that provides a region that can be grasped by a user to allow easy operation of the release handle. The release handle also includes profiled edges


306


that are used to operate the attachment clips. A detailed discussion of the release handle and the function of the profiled edges are provided in another section of this document.




The clip cover


302


provides multiple functions. First, the clip cover


302


operates to hold the attachment clips and their associated mechanisms in place. Thus, the attachment clips are secured to the bottom surface


210


of the attachment plate


104


and extend through openings in the attachment plate to protrude through the top surface


208


of the attachment plate


104


.




Second, the clip cover


302


operates to capture the release handle


206


so that the release handle is captured between the clip cover


302


and the bottom surface


210


of the attachment plate


104


. Furthermore, the release handle


206


is also captured between the attachment clips


204


so that the profiled edges of the release handle are adjacent to the attachment clips, respectively.




With the release handle


206


in the captured position, as described above, the release handle is free to move in or out, as shown by indicator


308


, and left or right, as shown by indicator


310


. Thus, the release handle may move in any combination of directions in a plane of movement that is parallel to the plane of the attachment plate


104


. This plane of movement will be referred to as a release plane. Movement of the release handle in the release plane causes the attachment clips to be spread apart from each other, which disengages the attachment clips from the clip receivers located at the bottom of the portable device, and thus releases the device from the attachment plate. As described below, the release handle may also be rotated in clockwise and counterclockwise directions to achieve the same functionality.





FIG. 4

shows an exploded view of the components of the embodiment of the invention shown in FIG.


3


. In this view, openings


402


in the attachment plate


104


can be seen. The openings


402


allow the attachment clips to pass through to the other side of the attachment plate so that they can be mated with clip receivers located on the portable device. The alignment pins


202


provide alignment and also secure the clip cover


302


to the attachment plate


104


, thereby capturing the release handle


206


.




The attachment clips


204


are part of a clip mechanism


404


that provides spring loaded tension that pulls the attachment clips toward each other. Operation of the handle


206


causes the attachment clips to be forced apart from each other (due to the edge profiles


306


), thereby allowing the attachment clips to be disengaged from the clip receivers of the portable device.





FIG. 5

shows a detailed view of a portion of one embodiment of an attachment clip mechanism


404


constructed in accordance with the present invention. The mechanism


404


includes attachment clips


204


, a spring


502


, and a clip track


504


. The spring


502


attaches to both clips


204


and exerts an inward force that pulls the clips together. The clips and spring are mounted in the clip track


504


.




The clip track


504


allows the clips to slide together or apart for selected distances so that the clips can engage and be disengaged from the clip receivers located at the bottom of a portable device. The clip track


504


includes additional features (not shown) that prevent the clips from being pulled together all the way, and prevent the clips from being spread apart so much that they escape from the clip track. Although one embodiment of the clip mechanism


404


is shown in

FIG. 5

, any other type of mechanism or arrangement of clips may be substituted provided that the other mechanism performs similar functions. Thus, embodiments of the invention are not limited to the use of the clip mechanism of FIG.


5


.





FIG. 6

shows functional top


608


and end


610


views of the release handle


206


and attachment clips


204


to illustrate how the profiled edges


306


of the release handle operate to spread apart the attachment clips when the handle is moved in any direction within the release plane.

FIG. 6

also illustrates that the attachment clips


204


are part of clip mechanism


404


that includes spring-loaded tension


602


that pulls the attachment clips toward each other.




The release handle


206


can be constructed from plastic, metal, cardboard, or virtually any other suitable material. The release handle can be divided into two regions. The first region is a handle portion


604


that provides a handle to allow a user to grasp the release handle during operation. The second region is a profile portion


606


that includes profiled edges


306


designed to spread the attachment clips. The profiled edges are identified as edges E


1


, E


2


, E


3


, and E


4


. When the release handle is moved in any direction within the release plane, the profiled edges operate to spread the attachment clips apart from each other by overcoming the spring loaded tension included in the clip mechanism


404


.




For example, moving the release handle in direction (D


1


) causes the profiled edges E


1


and E


4


to exert outward pressure on the release clips, thereby spreading the clips apart from each other. Similarly, moving the release handle in the direction (D


2


) causes the profiled edges E


2


and E


3


to exert outward pressure on the release clips, thereby spreading the clips apart from each other.




Because the release handle is captured by the clip cover (not shown in

FIG. 6

) and the attachment clips, moving the handle in the directions D


3


and D


4


causes the handle to move in a rotational motion. Thus, moving the release handle in the direction (D


3


) results in a clockwise rotation that causes the profiled edges E


2


and E


4


to exert outward pressure on the release clips, thereby spreading the clips apart from each other. Similarly, moving the release handle in the direction (D


4


) results in a counterclockwise rotation that causes the profiled edges E


1


and E


3


to exert outward pressure on the release clips, thereby spreading the clips apart from each other.




It is also possible to move the handle in the directions D


3


or D


4


without rotation if sufficient force is exerted to prevent the handle from rotating. Although this is not the preferred method, moving the handle in this way will also exert outward pressure on one release clip (the one in the direction of movement), thereby spread the clips apart from each other. For example, moving the handle in direction D


3


without rotation will cause edges E


3


and E


4


to exert an outward pressure on the adjacent release clip thereby spreading the release clips apart from each other.





FIG. 7

illustrates how the attachment clips


204


attach to clip receivers


702


located at a bottom surface


704


of a portable device


706


. For the purposes of clarity, the operation of only one attachment clip is shown in FIG.


7


. The attachment clip


204


extends through an opening


708


in the attachment plate


104


to attach to the clip receiver


702


. That attachment clip


204


includes a tapered edge


712


that allows a downward force


714


exerted by the portable device during installation to spread the attachment clips apart thereby allowing the attachment clips to enter the clip receivers


702


and lock into place to hold the portable device securely. The above installation process may be used to lock a portable device into a portfolio having a quick release latch as illustrated in FIG.


1


.




To release the attachment clip after it is locked into position within the clip receiver


702


, the user may move the release handle


206


, which operates to spread the attachment clips apart as discussed above. Therefore, using a quick release latch in accordance with the present invention, a user is able to quickly install a portable device into a secure attachment. The secure attachment may be part of a carrying accessory, such as a leather portfolio. During transportation of the device, the attachment clips maintain a secure grasp on the device so that it does not move or slide within the portfolio. When the user is ready to remove the device, the user may move the release handle in virtually any direction within the release plane, thereby spreading and disengaging the attachment clips from the device and allowing the device to be removed from the secure attachment.




Also shown in

FIG. 7

is a clip cover


302


that is mounted to the attachment plate


104


using the alignment pins


202


. The alignment pins


202


operate to align the attachment plate to the portable device so that the attachment clips will easily lock into place during the installation process. For example, the alignment pins


202


align with align openings


702


located in the bottom surface of the portable device. During installation, when the alignment pins and the alignment openings are aligned, the user may press the device onto the attachment place until the attachment clips lock into the clip receivers. When the attachment clips are locked, the device is securely attached to the attachment plate, which is part of the carrying accessory.




In accordance with the present invention, the device attaches to the attachment plate via the attachment clips and the clip receivers. Thus, there are no other means or mechanisms that hold the device to the attachment plate. Because of this, the device's display screen, buttons, and peripheral devices remain unobstructed and can be freely accessed. Therefore, the device is fully function while in the attached position and may be operated by a user without removing the device from the carrying accessory.





FIG. 8

shows another embodiment of a pivotless release handle


800


constructed in accordance with the present invention. The release handle


800


includes cam slots


802


. The cam slots


802


operate by guiding the release handle on pins (not shown) operating in cam slots to get an infinite variety of attachment clip motions and timing. For example, with a properly shaped cam slot it is possible to have two release points. The first release point partially releases the device to allow for rotation of the device in the portfolio. The second release point allows removal of the device. It is also possible to use the internal cam shape alone or in conjunction with the external cam edges. Thus, in one or more embodiments included in the present invention profiled edges or cam slot edges are used to provide for a pivotless release handle that operates to quickly release a device from a secure attachment.




The present invention includes a quick release latch for releasing a portable computer device from a secure attachment. The embodiments described above are illustrative of the present invention and are not intended to limit the scope of the invention to the particular embodiments described. Accordingly, while one or more embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit or essential characteristics thereof.
