MAGNETIC MEMBERS OF DOCKING DEVICES

BACKGROUND

[0001] Point-of-sale terminals are often fixed installation units. Recent developments have resulted in removable display terminals thai may be used by a salesperson to keep inventory, register sales, and the like, while carried around a retail or storage establishment. The system may then be brought back to a central location and docked. However, docking solutions may make using a portable display terminal awkward and detract from the aesthetics of the unit.

DETAILED DESCRIPTION

[0006] Examples disclosed herein provide a system including a docking device and computing device, such as a tablet computer of a point-of-saie terminal, which allows the use of an unobtrusive lock mechanism for mounting the computing device to the docking device. The docking device uses locking blades that, for example, travel along a 3-dimensionaS (3D) path to engage the computing device with the docking device, without interfering with the internal components of the computing device. As used herein, a 3D motion may include both a motion along an x-axis, for example, parallel to the face of a mounting device of the docking device, as well as motion along a z-axis, for example, perpendicular to the face of the mounting device. In one example, the vectors of the x-axis motion and the z-axis motion combine to give the locking blades an angular motion outwards from the face of the mounting device. As will be further described, movement of the locking blades may be controlled using magnetic members.

[0007] With reference to the figures, FIGs. 1A-B illustrate a system 100 including a docking device 1 10 and a computing device 120, according to an example. As illustrated, the docking device 110 includes a mounting device 102 to align with a mating cavity 1 12 of the computing device 120, While coupling the computing device 120 to the docking device 110, locking blades 104 may extend from the mounting device 102 into slots 114 in the mating cavity 112 of the computing device 120, Although two locking blades 104 {and corresponding slots 114} are illustrated, the number of locking blades may vary.

[0008] As an example, the mounting device 102 is minimal and unobtrusive. For example, when the computing device 120 is not mounted, as illustrated in FIG. 1A, the visible components of the mounting device 102 may include an angled plateau that resembles a male plug, and ends of the locking blades 104. On the computing device 120. the visible component may include the mating cavity 112, a

complimentary female recess to the male plug of the mounting device 102, including the slots 1 14 into which the locking blades 104 slide. As an example, both the male plug and the female recess are circular, and the wails of the piug and recess are angled. As a result, a user may be able to more easily find the correct position of the computing device 120 on the docking device 110, as well as providing a larger area for the locking blades 104 to join the computing device 120 and docking device 110 together.

[0009] As an example, magnetic members may initiate extension and retraction of the locking blades 104 from the mounting device 102 into and out of the slots 114 in the mating cavity 112 of the computing device 120. As illustrated, a first magnetic member 106 disposed within the mounting device 102 may be used to initiate the extension and retraction of the locking blades 104. As an example, the locking blades 104 include second magnetic members 108 to interact with the first magnetic member 106, As will be further described, this interaction between the first and second magnetic members 108, 108 may initiate the extension and retraction of the locking blades 104. [0010] As an exampie, the magnetic polarities of the magnetic members 106, 108 with respect to each other determines the force generated between them, that will then initiate either the extension or retraction of the locking biades 104, For exampie, when the magnetic members 106, 108 have the same polarity (e.g., N-N or S-S), a negative or repulsive magnetic force may be generated, whereas when the magnetic members 108, 108 have opposite polarities (e.g., N-S), a positive or attractive magnetic force is generated, in addition to magnetic polarity, the field strength of the magnetic members 106, 108 may be controlled to determine the magnitude of the magnetic force generated based on the magnetic polarities of the magnetic members 108, 108 with respect to each other,

[0011] Referring to FiG. 1 A, when the first and second magnetic members 106, 108 are to have opposite polarities, a resulting attractive magnetic force is generated (indicated by arrows). This positive or attractive magnetic force is to retract the locking blades 104 out of the slots 114 in the mating cavity 112, to undock the computing device 120 from the docking device 110, With the positive or attracting magnetic force retracting the locking biades 104 back into the mounting device 102, the locking blades 104 are out of the way while they are not in use.

[0012] Referring to FiG. 1 B, when the first and second magnetic members 106, 108 are to have a same magnetic polarity, a resulting repulsive force is generated (indicated by arrows}- This negative or repulsive magnetic force is to extend the locking blades 104 from the mounting device 102 into the slots 114 in the mating cavity 112. to dock and secure the computing device 120 to the docking device 110. As wilt be further described, the magnetic polarities between the first and second magnetic members 106, 108 may be adjusted to initiate the extension or retraction of the locking blades 104. This adjustment in magnetic polarities may be manual or automated,

[0013] FIGs, 2A-B illustrate a top view of a docking device 210, according to an example. The docking device 210 represents an example of the docking device 110 described above. To make clear the use of magnetic members to initiate the extension and retraction of locking blades 104, a mounting device of the docking device 210 is removed, to expose internal components of the docking device 210, As an example, an Interaction between a first magnetic member 206 and second magnetic members 208 of the locking blades 104 initiates the extension and retraction of the locking blades 104.

[0014] Referring to FIG. 2A, when the first magnetic member 206 is slid to a first position, indicated by arrow 202, the first and second magnetic members 206, 208 are to have opposite magnetic polarities with respect to each other. For example, the north end of the first magnetic member 208 is opposite from the south end of second magnetic members 208, Similarly, the south end of the first magnetic member 206 is opposite from the north end of second magnetic members 208. As a result, an attractive magnetic force is generated and a retraction of the locking blades 104 are initiated, as illustrated by arrows 204. As an example, the first magnetic member 208 may be moved manually or automatically, for example, by a motor or solenoid.

[0015] Referring to FSG. 2B, when the first magnetic member 206 is slid to a second position, indicated by arrow 212, the first and second magnetic members 208, 208 are to have a same magnetic polarity with respect to each other. As mentioned above, the first magnetic member 206 may be moved manually or automatically, for example, by a motor or solenoid, in addition, rather than being moved downward to the second position illustrated in FiG. 2B, the first magnetic member 206 may also be moved upward. Referring to the position illustrated in FIG. 28, the north end of the first magnetic member 206 is opposite from the north end of second magnetic members 208, As a result, a repulsive magnetic force is generated and extension of the locking blades 104 are initiated, as illustrated by double-sided arrow 214. By relying on the arrangement of the first and second magnetic members 206, 208 with respect to each other, the number of interna! components in the docking device 210 for initiating the extension and retraction of the locking biades 104 may be kept to a minimum.

[0018] FIGs. 3A-B illustrate a cross-section of a docking device 310 that the computing device 120 may dock to, according to an example. The docking device 310 represents an example of the docking device 110 described above. The cross- section of the docking device 310 makes clear the use of magnetic members to initiate the extension and retraction of locking blades 104, As an example, an interaction between a first magnetic member 308 and second magnetic members 308 of the locking blades 104 initiates the extension and retraction of the locking biades 104,

[0017] Referring to FSG, 3A, when the first magnetic member 306 is slid to a first position, indicated by arrow 302, the first and second magnetic members 306, 308 are to have opposite magnetic polarities with respect to each other, for example, the north end of the first magnetic member 306 is opposite from the south end of second magnetic members 308. As a result an attractive magnetic force is generated and a retraction of the locking biades 104 are initiated, as illustrated by arrows 304. As an example, the first magnetic member 306 may be moved manually or automatically, for example, by a motor or solenoid,

[0018] Referring to FIG, 38, when the first magnetic member 306 is slid to a second position, indicated by arrow 312, the first and second magnetic members 306, 308 are to have a same magnetic polarity with respect to each other. As mentioned above, the first magnetic member 306 may be moved manually or automatically, for example, by a motor or solenoid. Referring to the position illustrated in FIG, 36, the south end of the first magnetic member 306 is opposite from the south end of second magnetic members 408, As a result, a repulsive magnetic force is generated and extension of the locking blades 104 are initialed, as illustrated by arrows 314, This magnetic force may then dock the computing device 120 to the docking device 310, upon the locking biades 104 entering the mating cavities 114. By relying on the arrangement of the first and second magnetic members 306, 308 with respect to each other, the number of internal components in the docking device 310 for initiating the extension and retraction of the locking blades 104 may be kept to a minimum,

[0019] FIGs, 4A-B illustrate a top view of a docking device 410, according to an example. The docking device 410 represents an example of the docking device 110 described above. To make clear the use of magnetic members to initiate the extension and retraction of locking blades 104, a mounting device of the docking device 410 is removed, to expose interna! components of the docking device 410, As an example, an interaction between a first magnetic member 406 and second magnetic members 408 of the locking blades 104 initiates the extension and retraction of the locking blades 104. As illustrated, the first magnetic member 408 is circular and diametrically magnetized. The number of sections of the first magnetic member 406 that is diametrically magnetised may be based on the number of locking blades 104. For example, with two looking blades 104, as illustrated, the first magnetic member 406 may be diametrically magnetized into four quadrants.

However, if a docking device has only one locking blade, the first magnetic member may be diametrically magnetized into two semicircles.

[0020] Referring to FIG. 4A, when the first magnetic member 406 is rotated

(indicated by arrow 402) a quarter turn (e.g., 45 degrees) to a first position, the first and second magnetic members 408, 408 are to have opposite magnetic polarities with respect to each other. For example, the quadrants of the first magnetic member 408 having a south pole are opposite from the north end of second magnetic members 408. As a result, an attractive magnetic force is generated and a retraction of the locking blades 104 are initiated , as illustrated by arrows 404. As an example, the first magnetic member 406 may be moved manually or automatically, for example, by a servo motor.

[0021] Referring to FIG.4B, when the first magnetic member 406 is rotated another quarter turn to a second position, the first and second magnetic members 406, 408 are to have a same magnetic polarity with respect to each other. Rather than being rotated clockwise to the second position illustrated In FIG. 4B, the first magnetic member 408 may also be rotated counterclockwise. Referring to the position illustrated in FIG, 4B, the quadrants of the first magnetic member 406 having a north pole are opposite from the north end of second magnetic members 408. As a result, a repulsive magnetic force is generated and extension of the locking blades 104 are initiated, as illustrated by arrows 414. By relying on the arrangement of the first and second magnetic members 406, 408 with respect to each other, the number of internal components in the docking device 410 for initiating the extension and retraction of the locking blades 104 may be kept to a minimum.
