The present invention relates to security slot attachments to provide for the security of portable electronic devices, such as computers, laptops, notebooks and the like. The present invention also relates to a locking assembly for tablet computers (i.e. iPad®), smart phones, electronic books known as “e-readers”, and other hand-held personal digital devices, as well as to plunger security locks, and to laptop computers, notebook computers and other hand-held electronic devices such as cell phones, personal digital assistants, personal music and/or video players (i.e. iPod®), etc., without limitation, which are configured for operational use with a locking assembly associated with such a plunger security lock.
Portable devices such as computers or other similar equipment are often supplied with a small security slot in their housing to provide an attachment for a security cable anchored to an immovable object. It is advantageous for the attachment device in the slot to be easily removable when the security cable is no longer required. The slot is approximately 3 mm by 7 mm.
U.S. Pat. No. 6,317,936 of McDaid et al. describes a security anchor comprised of an internal member, an external member and a screw to lock the external member to the exterior of the equipment housing by engaging the internal member within the security slot. The internal member has an bent over end that fits inside the security slot with the screw loosened and then locks to one long edge of the security slot at the inside of the equipment housing when the screw is tightened. A screw driver is required to engage and disengage the security anchor.
U.S. Pat. No. 6,513,350 of Hurd et al. describes two different devices to provide attachment to the security slot. They both involve the insertion of a locking member slightly smaller than the slot dimensions shaped as a rectangle with rounded ends on the small dimension being aligned with the security slot, inserted, and then turned 90 degrees whereby its length would prevent its exit until rotated again into alignment. In the first embodiment, a partitioned cylinder with a locking member extending from the bottom on one half on a rod is first inserted into the security slot and rotated 90 degrees. The mating half of the cylinder with a protruding bar on the bottom is then mated with the first half with the bar end also entering the security slot. The geometry is such that in this configuration with two cylinder halves together, the cylinder cannot be rotated and is prevented from exiting the security hole. A cable threaded through two aligned transverse holes in the two halves will keep the attachment cylinder secured to the outer equipment housing around the security slot. The attachment cylinder which comprises two separate parts can again be removed from the security slot when the security cable is removed.
The preferred embodiment of the Hurd patent ('350) shows a specialized combination lock with a locking member at the distal end of an extended rod emanating from one end. A retaining member, also further down on the locking member rod senses the outer equipment housing wall after the locking member is rotated 90 degrees, and locking pins are engaged by retraction of the rod by the lock preventing the locking member from rotating back into alignment with the security slot thereby securing the combination lock to the equipment housing. The combination lock is attached to a security cable. Upon entering the proper combination, the rod at the end of the lock is again extended releasing it from the security slot.
U.S. Pat. No. 7,100,403 of Murray, Jr. Et al. describes a variety of cable-attached locks which engage the long ends of a security slot by distal engagement wings on arms which expand or are locked in a spread-apart configuration after they are compressed together for insertion. In addition, similar engagement of non-lock security slot attachment devices using resilient engagement fingers with side wings using screw or other mechanical locking methods are also illustrated. A lock with a rotating locking member on a rod is also described. After inserting by alignment through the security slot, the locking member is rotated 90 degrees after which two rods extend from the end of the lock into the distal ends of the security slot preventing rotation back into alignment of the locking member.
The prior art does not show a security slot engagement device that is inexpensive to manufacture, interfaces to a variety of locks or cables, has no separable parts, is easy to use, and requires no tools for installation or removal.
Additionally, notebook computers, tablet computers or other personal electronic devices are increasingly used by students at educational institutions. They are also used by workers at job sites. Notebook computers are often referred to as laptop computers, meaning a portable, foldable computer which can be used while positioned upon the user's lap. In some instances, “laptop computer” refers to the term used in the trade for an older version of a larger portable computer. However, with increasing streamlining and downsizing of portable computers, compact, smaller versions are referred to as “notebook computers”, but the terms are generally interchangeable.
Personal electronic devices, such as tablet computers (i.e. iPad®), cell phones, smart phones, personal digital assistants, personal music and/or video players (i.e. iPod®), etc. without limitation, can be used just about anywhere. Other personal digital assistants, including electronic books, known as “e-readers”, such as the Nook®, can download virtual images of books.
In order to safeguard the personal electronic device, such as a tablet computer, a notebook computer, smart phone, e-reader or personal music and/or video player, it must be shut down, closed and transported by the user.
However, it is often advantageous for the user of a tablet computer, notebook computer or other personal electronic device to take a break and leave the device/computer open and operable at a work station, library study carrel, etc., with other papers and books left at their current open position. This leaves the personal electronic device, such as a tablet computer or notebook computer, vulnerable to theft.
Moreover, in the commercial retail environment, it is advantageous to display consumer electronic devices, such as tablet computers, notebook computers, cell phones or personal digital assistants in a secure but visually accessible display.
For that matter, various security devices are known for securing personal electronic devices configured for use with the known security devices.
For example, U.S. Pat. No. 6,755,056 of Igelmund (the '056 patent), discloses a security device (e.g., male lock fitting 100) for securing portable equipment having a security slot in the chassis of the equipment, and adaptor for adapting electronic portable equipment without a slot for use with the security device. The security device (100, 100′) is tethered to a piece of heavy furniture or otherwise immovable structure, typically with a braided cable or like means, and includes an attachment with a slot mating head and an axial movable head locking member. This is inserted into the slot in the housing of the electronic equipment (or in the adaptor affixed to the housing where there is no slot) after the slot mating head to prevent rotation and removal of the head from the slot.
For example, the FIG. 7 security device (100′) is inserted into a lock fitting receptacle 106 where pin 104 passes through the head locking aperture 25 into mounting end 22 and into slot opening 12. When fully inserted, the housing lockably engages the fitting by way of conventional locking mechanisms, such as fixed or retractable teeth 108, 108′ on the male lock fitting and teeth engaging notches 110 within the receptacle, so the pin is secured in the head locking position.
One of the shortcomings of the '056 patent, however, is that the security provided is only as strong as either the housing material and therefore slot integrity, or the adhesive adhering the adaptor to the housing. A thin, sheet-metal housing is pliable and a plastic housing is frangible, allowing for easy removal of the attachment with slot mating head and axial moveable head locking member, once in place.
The aforementioned U.S. Pat. No. 6,513,350 of Hurd (the '350 patent), discloses a physical security system comprising a combination lock for connecting specially designed security slots in portable electronic devices, such as a notebook computer. Like the '056 patent, the security device of '350 patent operates with a portable computer with a wall 10 having an inner surface 20, which wall is configured with a slot 15. A lock interface 25 is engageable with wall 10 through slot 15. A locking mechanism 30 comprising a tethering cable and lock 40 allows that, upon inserting lock interface 25 in slot 15 and engaging the interface with inner surface 20, the lock interface is then attached to a stationary object with lock 40 and cable 40.
FIG. 6 shows an alternative locking system 600, including a housing 605 and slot engagement member 610 with locking member 615 and retaining member 620. Engagement member 610 is coupled to the housing 605 so that it moves between an extended and retracted position. Two pins 625 extend from the housing 605 and are located on opposing sides of a shaft of engagement member 610. The housing 605 includes a combination lock mechanism 630 for interacting with the engagement member 610 and retaining in the retracted position until the correct combination coed is dialed in to the lock mechanism.
Also like the '056 patent, however, the security provided by the '350 patent is only as strong as the housing material and therefore slot integrity. Moreover, and as is readily apparent in FIG. 6, there does not appear to be a means for effecting retraction and extension of pins 625 to/from housing 605, or means for comfortably grasping the lock mechanism to articulate slot engagement member in the slot 660 in wall 650 (FIG. 6).
It is therefore an object of the present invention to provide a security slot attachment to provide security for portable or stationary electronic computing devices.
It is also an object of the present invention to provide a lock attachment for a portable electronic computing device which retrofits into a rectangular slot of the housing of the portable electronic computing device and which prevents theft thereof.
It is also therefore an object of the present invention to provide a locking assembly security apparatus for a non-foldable tablet computer, e-reader or smart phone preferably associated with a plunger-type security lock or other locking device, and an electronic device configured to be secured in cooperation with the locking assembly and plunger-type security lock, which overcome the shortcomings of the prior art.
Other objects which become apparent from the following description of the present invention.
The present invention is a security slot attachment device that is comprised of several major parts secured together by pins which permit movement among the parts to facilitate engagement with the security slot and removal therefrom, without the use of any tools. The parts themselves, typically four in number, can be machined of aluminum or stainless steel, molded from a wide variety of rigid plastic resins, die cast from zinc-aluminum alloys, or molded using a metal injection molding process.
In general, the lock of the present invention includes an assembly of a slot engaging member insertable in a slot of a piece of equipment being locked, such as a portable or desktop computer, a laptop, notebook or other handheld electronic device, a monitor, a television/video screen, a video game, an electronic instrument such as an oscillator or a medical centrifuge or other analytical device, or the like. The slot engaging member is lockable by a dual action rotation and pivoting of an anchor sub-assembly grasping the slot engaging member; whereby the slot engaging member is unlocked by a reverse dual action pivoting and rotation of the anchor sub-assembly for the slot engaging member; wherein the lock is locked without use of a tool.
For example, the lock assembly includes the rotatable locking member insertable within a slot in a housing of an electronic equipment. The rotatable locking member engages with the anchor sub-assembly having a rotatable element, where the rotatable element communicates with a pivotable member having a recess through which a further locking member is inserted, wherein said lock is locked without use of a tool.
In the embodiment with four major parts, there are a locking element, a guide, a pivot block, and a locking plate, arranged in an array in that sequential order. The locking element is a rod with an elongated locking end centrally attached to a distal end of the rod, forming a T-shape rod end, which is insertable and rotatable within a rectangular slot in the housings of portable or stationary computing devices. The guide is a generally flat substrate block having the same crossection as the elongated locking end at its front portion. The guide also has a central hole, and a top portion with extended wings. The pivot block is preferably a short rectangular shaped cylinder, preferably round shouldered, with a large hole to accept the free end of the locking rod therein, opposite to the T-shaped slot engaging end of the locking element, and small holes, such as two small holes, to accept fasteners, such as pins. The locking plate is preferably a thick rectangular plate with a large hole, such as, for example, a rectangular hole, in its center and a pair of two transverse holes in positional register for a pivoting pin or axle insertable therein, to permit pivoting of the pivot block within the large hole of the locking plate.
The assembly of the four parts is as follows. The guide part is engaged onto the rod of the locking element; and the central hole of the guide is sized to allow it to rotate freely. The free end of rod is then inserted into the snug large hole of the pivot block and the transverse hole near the end of the rod (now capturing the guide) is aligned with the small hole through the side of the pivot block at the large hole site. The rod and the pivot block are then rigidly attached by a small short force-fit pin. This anchor subassembly of three major parts is now attached to the locking plate by inserting the distal end of the pivot block into the large rectangular hole, aligning the transverse clearance hole with the force-fit holes in the locking plate and pushing the longer pin through the locking plate and the pivot block. The distal end of the large rectangular hole (away from the pivot block) is used for security attachments, such as the prong or other protruding element of a lock.
The size of the locking end of the rod and the distal portion of the guide is just slightly smaller than the dimensions of the rectangular security slot of the housing of the computing device, such as a laptop or other portable or fixed computing device. To attach the security slot attachment of this invention to the security hole, the locking end is aligned with the end of the guide and both are inserted through the security slot with the wings of the guide resting on the outside surface of the device housing. The locking plate is turned 90 degrees in its own plane, and then the locking plate is pivoted up 90 degrees so that the side of its pinned end now rests against one long side of the guide that protrudes from the housing. In that position, the locking plate and the attached locking end within the housing cannot be rotated and therefore are locked to the housing. Anything inserted through the protruding tang formed by the pivoted locking plate that will prevent it from pivoting back will keep the attachment secured to the housing. A cable, a properly sized loop of an ordinary padlock, or a specialty locking prong engaging the tang will suffice. To remove, the attachments are removed from the protruding tang, the locking plate is pivoted 90 degrees, rotated 90 degrees in its own plane, and the attachment is pulled out of the security hole.
An optional washer of compressive elastomer foam can be slipped onto the insertable portion of the guide for a snug locking feel which would also eliminate the possibility of buzzing or other noise induced by vibration. The elastomeric foam washer lies flattened somewhat between the winged portion of the guide and the equipment housing when attached.
In a preferred embodiment of the security slot attachment, two parts are modified. The pivot block has three corners rounded for a better operational fit. Also, the guide has one long side of the winged portion (which sits above the housing when attached) made wider. The locking plate can only lock against the other narrow side in the new embodiment. This change enhances security because it denies access to both sides of the security slot (for malicious prying with a tool) when the attachment is installed.
In another embodiment, the invention comprises a locking bar associated with a plunger-type or other security lock comprising a cradle including at least one diagonally extending chassis bar with respective pockets at opposite ends, wherein one of the pockets is hingeably releasable to insert one corner of the tablet computer, smart phone, e-reader, or other hand held personal digital assistant device therein while the other end is a non-hingable pocket into which the opposite corner of the tablet computer, smart phone, e-reader or other hand held personal digital assistant is inserted therein. The hingeable pocket includes a hingable housing which pivots to allow insertion of one corner of the device to be inserted therein, after the opposite corner has already been inserted in the slot of the fixed, non-hingable pocket at the opposite side of the at least one chassis bar. The chassis bar is preferably adjustable in length, to allow for different sized devices to be locked therewith. Although there is preferably one diagonal chassis bar with opposite corner pockets to receive one of respective diagonally opposed corners of the device, it is contemplated that more than one chassis bar can be utilized, and/or comprise a frame with at least a pair of pockets each pocket supporting a respective corner of the device therein. One end of the chassis bar is configured as an axially extending flange with an aperture hole, which flange is insertable within a corresponding slot in lock having a movable pin or hook of a combination lock and locking mechanism in a housing.
For example, in a preferred embodiment, the security apparatus of this invention is designed to engage diagonal corners of an electronic tablet (such as an iPad®. The locking assembly apparatus engages with a tablet computer or similar device, which is securely locked to it via a combination pin lock, such as, for example, a plunger lock. A respective distal corner pocket engages one corner of the tablet computer, while a respective proximal lockable corner pocket engages the diagonally opposite corner of the tablet computer. The security apparatus includes a chassis bar, such as a flat metal chassis bar connecting the fixed distal pocket to the diagonally opposite proximal hingable pocket.
The base of the proximal pocket extends from the attachment portion to the diagonally extending chassis bar to the flanges at the proximal end on the other side of the integral hinge pin housing of the proximal pocket, which flips up to permit a corner of the tablet computer or other device to be inserted or disengaged. The hingable tail section of the flange fits between the forked flange protrusions of the base of the proximal hingable pocket; when it is co-planar with the base and the slot of the pin lock can be fit over the end and locked by its pin engaging the hole within the hingable tail section of the hingable pocket, to complete the locking procedure.
Although a pre-determined sized security apparatus can be provided for the size most popular tablets or similar devices on the market, an adjustable single unit can also be provided as an alternate embodiment. In one embodiment, the adjustability feature is formed by permitting the metal chassis bar to slide through a slot in a modified distal pocket. An array of holes in the chassis provides the adjustability by virtue of a friction fit removable locking pin The pin cannot be taken out once the tablet computer is engaged, but it is simply lifted up for adjustment to permit the pocket to slide on the bar.
Another adjustable embodiment uses a two-part telescoping metal chassis bar. This embodiment is more compact for smaller tablets or like items since there is no distal metal bar extending beyond the distal engagement pocket.
While any kind of plunger type pin lock having a slot and movable pin or hook can be utilized, in another embodiment a connector is provided connecting permanently connecting the locking housing to a tether, a plunger operational in cooperation with locking mechanism and a sliding key operate to lock the tether to a one end of a locking strip, which end extend part way through the electronic device. The other end of the locking strip comprises wedge stop, to prevent the locking strip from passing all the way through the housing, for example, a hinge gap between upper and lower housings.
The plunger-type security lock preferably operates by grasping the housing, dialing in a correct combination and pushing the plunger through the hole associated with one of the pockets. In another embodiment the plunger is pushed to extend the sliding key from a housing in order to engage a portion of the locking member. Once engaged, and upon release of the pushing force, the sliding key retracts the engaged portion of the locking member at least partially into the housing, and maintains it until the combination locking mechanism is unlocked.
In another embodiment, the invention comprises an electronic device configured for allowing a locking member to pass partially through, but not completely through some part of the electronic device chassis or housing, a locking member and a plunger-type security lock configured for lockingly engaging some part of the locking member once passed through the chassis or housing part.
When locked in place, the notebook computer or other personal electronic device is secure from being taken away from the surface to which it is locked. Furthermore, taking advantage of software and/or software/biometric security systems, the computer or other personal electronic device will also be unusable by unauthorized individuals when its owner is away from the area for a break, telephone call, or other short-term pursuits. With a few keystrokes, the owner of the computer or other personal electronic device can resume activity in exactly the same place as when activity had been suspended. This is especially useful for leaving an active computer or other personal electronic device on a study desk or library carrel.
In an alternate embodiment, a security slot attachment locking device incorporates a compression spring to facilitate easy attachment and detachment of the locking device from the object being locked, such as, for example, a portable computer or other portable electronics device having an elongated security slot in its housing. The locking device includes a tang support, such as, for example, preferably a flat plate element which has an engagement tang at the forward end, with a hole at an opposite end of the tang support plate for insertion of a coupling lock or for cable access for locking adjacent the rear distal end of the flat plate element, and a central elongated access hole for engaging the compression spring, all fitting within a housing, such as, for example, a clamshell housing.
A coupling lock engageable with the security slot attachment may be, for example, a combination lock, a padlock with a U-shaped shackle, a protruding lock with a rod or plate, a lock with a slot insertable movable tang, a plunger lock, or any other portable lock known to those skilled in the art of locking portable devices.
The clamshell housing of the security slot attachment preferably has two protruding front extensions on either side of the flat plate engagement tang. The engagement tang fits through the security slot of the device being locked, when aligned so that its width fits through the length of the security slot, and the plate then necks down so that the neck portion can be rotated within the security slot.
In operation, the back end of the flat plate is pushed forward so that the plate slides forward within the clamshell housing against spring force, thereby pushing the front tang forward beyond the adjacent protruding extensions exposing the neck. In this position, the tang is inserted within the security slot and then rotated 90 degrees in either direction such that the tang ends engage the inside surface of the device housing, above and below the security slot of the device being locked. The rear force is then released, permitting the spring to withdraw the tang inward and drive the two housing extensions inside the security slot on either side of the now locked tang. The hole near the distal end of the tang support plate in now exposed at the rear since it protrudes rearward from the housing end. A coupling lock or a secure cable engaging through this hole will prevent the tang support plate from being moved forward within the housing thereby locking it to the device housing.
To remove the security slot attachment device of the alternate embodiment, the coupling lock or cable is removed from the distal hole and this back end of the tang support plate is again pushed forward against spring force. The attachment is then rotated 90 degrees in either direction and just withdrawn from the security slot of the device.
This embodiment has ergonomic features which enhance usability. It is more intuitive in operation as it provides finger grasping wings to facilitate pushing on the rear of the plate. The spring also holds the attachment device snugly against the device housing, thereby facilitating the use of both hands (if desired) to attach or remove the cable or coupling lock.

Security apparatus 600 is more clearly shown in
Although purpose-sized security apparatus 600 of this invention can be provided for the most popular tablets or similar devices on the market, an adjustable single unit can also be configured. In one embodiment, the adjustability feature is formed by permitting metal chassis bar 624 in
Another adjustable embodiment 640 shown in
A further embodiment for a security slot attachment assembly is shown in
During security slot attachment 720 assembly, rod 732 is inserted is inserted and passed through through hole 743. A portion of the rod that extends out of guide 740 is inserted into a (in a snug fit) hole 751 of a pivot block 750. Pivot block 750 also includes two transverse holes 752 and 753. Transverse hole 733 of rod 732 is aligned with transverse hole 752 of pivot block 750 and pin 755 is inserted in a press fit to secure the rod to the pivot block. While the locking element 730, guide 740 and pivot block 750 form a subassembly of three parts, locking element 730 (including rod 732 and locking end 731) and pivot block 750 operate together as one functional unit, which further includes guide 740 when assembled into a sub-assembly.
The last member of the security slot attachment 720 is lock plate 760, with larger rectangular locking hole 761 and pivot bar hole 762. The lock plate 760 functions to prevent further movement of the locking element 730 (including rod 732 and locking end 731), guide and pivot block 750 after placement in equipment by attachment of a locking device through rectangular locking hole 761. The final assembly step is to invert the subassembly so that hole 753 of pivot block 750 can align with holes 762, in positional registration with each other, and of lock plate 760. Pin 764 is a press fit in lock plate 760 but a clearance fit in block 750. When pin 764 is pressed through lock plate 760 and pivot block 750, the assembly is complete as shown in
An assembly of an embodiment of security slot attachment 795 is shown in
Also, like security slot attachment 720, the length “L” and width “W” of locking end 731 are slightly less than the slot 710 dimensions of computer equipment housing 700. However, guide 790 has a different configuration than guide 740 (
Exterior or front portion 791 of guide 790 rests on the exterior surface of computer housing 700 upon insertion of extended front portion 741 and locking end 731 through the slot 710 in equipment 700 during use. During assembly, rod 732 of locking element 730 is inserted through hole 743 of guide 790 and then into (in a snug fit) hole 751 of pivot block 780. Hole 733 of locking element 730 is aligned with hole 752 and pin 755 is inserted in a press fit. This forms a subassembly of the locking element 730, locking guide 790 and pivot block 780. The final assembly step is to invert the subassembly so that hole 753 of pivot block 780 can align with holes 762 of lock plate 760, once pivot block 780 is placed within the large rectangular hole 761 of block plate 760. Pin 764 is a press fit in lock plate 760 but is a clearance fit in block 780. When pin 764 is pressed through holes 762 of plate 760 and hole 753 of block 780, the assembly is complete (
