[0005] The invention relates to a mechanical device for securing an electronic device having a hinged member and a base portion to a support.

[0006] A track is adapted to be secured to the support. The track may be grooved, perforated or otherwise adapted to receive one or more retainers. A first and second retainer are engagable in the track and include an aperture for receiving an elongated fastener. The first and second retainer are positionable in the track so as to define a space accommodating a base portion of the displayed electronic device. The first and second retainer may preferably include a shoulder portion for engaging a groove in the track.

[0007] A first and second set of spacers are disposed in a stacked manner over the first and second retainer respectively. Each set of spacers includes a plurality of spacers comprising a protrusion disposed on a first surface, a complementary recess disposed on a second surface and a through-hole for receiving an elongated fastener.

[0008] A slotted member, through which a hinged member of the electronic device may be inserted, is disposed over a selected one of the plurality of spacers from each of the first and second sets of spacers. The slotted member is supported by the first and second set of spacers and spans between the first and second retainer. Preferably, the slotted member spans between the retainers substantially parallel to the track, but the slotted member may also be disposed at an angle to the track.

[0009] First and second elongated fasteners are insertable through the slotted member and through first and second sets of spacers, respectively and are engagable with first and second retainers for securing the electronic device to the support.

[0010] A first and second cap having a through-hole for receiving the elongated fastener may be disposed over the respective first and second sets of spacers. The cap may have a recess disposed in a top surface of the cap. A fastener cover comprising a cup-shaped member having a through-hole for receiving an elongated fastener and a flexibly coupled top portion for concealing the elongated fastener may be disposed in the cap recess.

[0011] The retainer device may have a third set of spacers disposed over the support and a front grip disposed over a selected spacer from the third set of spacers. The third set of spacers and front grip may include a through-hole for receiving an elongated fastener. A bottom spacer of the third set of spacers may be secured to the support using, for example, a strip of double-sided adhesive tape, glue or other adhesives.

[0012] The front grip may be disposed over a front portion of the base portion of the electronic device and may be positionable so that it interferes with the functioning of the electronic device. Alternatively, the front grip may be positioned so that it does not interfere with the functioning of the electronic device.

[0013] A receiving element having an aperture for receiving an elongated fastener may be disposed under the support. The elongated fastener may be insertable through the front grip and third set of spacers and engagable with the receiving element to secure the electronic device to the support. Additionally, a segment of the track may be secured to a support at a front portion of the electronic device. The elongated fastener may be insertable through the front grip and third set of spacers and engagable with a retainer which engages the track. The elongated fasteners may be, for example, threaded fasteners and the apertures in the retainers and in the receiving element may be threaded apertures. The threaded fasteners may be tamper proof screws.

[0014] Additionally, a length of track may be secured to the support adjacent to a front portion of the electronic device. The front grip may be disposed over a selected spacer from the third group of spaces and a top cap disposed over the front grip. The front grip, spacer and top cap assembly may be secured to the track with an elongated fastener which extends through the top cap, front grip and spacers and engages a retainer which is engaged with the length of track in the manner as described for securing the slotted member.

[0015] The electronic device may be secured at one or both sides of the device with a side retainer assembly which may comprise one or more spacers, a side grip, top cap, and an elongated fastener which extends through the top cap, side grip, spacers and a through-hole in the support and engages a receiving element disposed on an underside of the support.

[0016] A rear portion of the electronic device may be secured with a rear retainer assembly which may comprise one or more spacers, a top cap, a rear grip and an elongated fastener which extends through the top cap, rear grip, spacers and a through-hole in the support and engages a receiving element disposed on an underside of the support. The rear grip may be positioned adjacent to a rear portion of the base of the electronic device so as not to interfere with the opening and closing of the hinged member of the electronic device. The rear retainer assembly may also be secured to a length of track in the manner of the front grip assembly or slotted member.

[0017] An advantage of a retainer device according to an embodiment of the invention is that a retainer device is provided which is easily installed and adjustable to accommodate displayed electronic devices of various proportions. Another advantage of a retainer device according to an embodiment of the invention is that a displayed electronic device may be secured such that its functioning or operation is either interfered with or not interfered with, depending on the requirements of a particular application for the retainer device.

[0018] A further advantage according to an embodiment of the invention is that an aesthetically pleasing retainer device is provided, wherein sets of stacked spacers of the same height may be associated with a number of displayed electronic devices of different heights.

[0026] Referring now in detail to the drawings and, in particular, FIG. 1 shows a perspective view of a retainer device 10 for securing a displayed electronic device 1 to a support such as support 2. Displayed electronic device 1 has a hinged member 3 and a base portion 4. Electronic device 1 may comprise, for example, a laptop personal computer, a digital video disk (DVD) player or another hinged or clamshell-configured electronic device. Hinged member 3 may be a display screen portion of electronic device 1.

[0027] Support 2 may be, for example a countertop, table top, shelf or other object of sufficient size to deter unauthorized removal of an electronic device when secured thereto. Preferably, support 2 comprises a substantially flat, rigid surface.

[0028] In the embodiment shown in FIG. 1, retainer device 10 includes a track 5 adapted to be secured to support 2, first and second elongated fasteners 120, 220, first and second retainers 11, 21, a first set and a second set of spacers 14, 24 and a slotted member 6.

[0029] Preferably, track 5 is grooved, however, track 5 may include perforations that receive elongated fasteners 120,220 at selected longitudinal locations. As shown in FIG. 1, track 5 is adapted to be secured to support 2. For example, track 5 may be screwed, bolted, adhered or otherwise fastened to support 2. Track 5 may extend in a lengthwise direction along support 2 and multiple displayed electronic devices may be secured using a single length of grooved track. Track 5 may be formed from any suitable material, for example, from extruded aluminum and may be provided in pre-cut lengths to fit standard shelf lengths or cut to custom lengths. Track 5 may have a cross sectional profile as illustrated in FIG. 1, wherein track 5 has a relatively narrow opening along a top surface and a relatively wider opening along an inner portion.

[0030] As shown in FIG. 1, a first retainer 11 and a second retainer 21 are positionable in track 5 so as to define a space which can accommodate a displayed electronic device 1. First and second retainers 11, 21 may be positioned at various distances from one another along track 5 and in this way displayed electronic devices of various sizes may be secured with a retainer device according to an embodiment of the invention.

[0031] As shown in FIG. 1, each of first and second retainers 11, 21 may engage track 5. For example, retainers 11,21 may include an appropriately dimensioned shoulder portion 12, 22 for engaging track 5. Retainer shoulder portion may be configured, for example, so that retainers 11, 21 may be inserted into an opening in a top surface of track 5 from above with a major dimension of shoulder portion 12, 22 substantially parallel to a length of track 5. However, retainers 11, 21 may be constructed so as to engage track 5 by an interference fit or other suitable connection to prevent lateral or upward mobility of retainer device 10.

[0032] First and second retainer 11, 21 may also include an aperture portion 13, 23 for receiving elongated fasteners 120, 220. Aperture portion 13, 23 may have an internal thread for receiving and coupling with a threaded elongated fastener, such as a screw or bolt. An installation of an elongated fastener 120, 220 in retainer 11, 21 may locate and engage retainer 11, 21 in track 5.

[0033] For example, when elongated fastener 120, 220 is inserted through aperture portion 13, 23 of retainer 11, 21, elongated fastener 120, 220 may contact track 5 and retainer 11, 21 may move upwardly and rotate to within track 5. Retainer 11, 21 may rotate through an angle within a range of approximately 40-60 degrees, for example 45 degrees, with respect to a length of track 5. As retainer 11, 21 is rotated, shoulder portions 12 and 22 engage track 5. In this way, elongated fasteners 120, 220 may interface with retainers 11, 21 so as to automatically cause retainers 11, 21 to engage track 5.

[0034] First 14 and second 24 sets of spacers may be disposed over first 11 and 21 second retainers, respectively as shown in FIG. 1. Each set 14, 24 of spacers may include a plurality of spacers, such as spacers 15, 25, which are arranged in a stacked manner over each retainer 11, 21. Each individual spacer may be, for example, an annular disk with two substantially flat opposite surfaces having a protrusion on one surface and a complementary recess on an opposite surface. When spacers 15, 25 are stacked on top of one another, a protrusion 16, 26 of one spacer may fit into a recess 17, 27 of an adjacent spacer in a substantially interlocking manner. Spacers 15, 25 may be arranged so that protrusions 16, 26 face in a downward direction toward support 2 and complementary recesses 17, 27 face in an upward direction. Alternatively, spacers may be arranged so that a protrusion faces upward and a recess faces downward. Spacers 15, 25 may also include a through-hole 18, 28 extending through a thickness of spacer 15, 25 for receiving an elongated fastener 120, 220. Through-hole 18, 28 may be disposed at a center of spacer 15, 25.

[0035] A slotted member or screen bar 6 may be disposed over and supported by a selected spacer from first 14 and second 24 set of spacers. Slotted member 6 may be arranged so that it spans substantially between first 11 and second 21 retainer and extends substantially parallel with or at an angle to a length of track 5.

[0036] Slotted member 6 may be formed from a substantially rigid material, for example, molded plastic, extrusion grade ABS, wood, or any other suitable material. A slotted portion of slotted member 6 is dimensioned so that a hinged portion 3 of a displayed electronic device 1 is insertable through slotted member 6. Slotted member 6 may include through-holes at one or more ends of a slotted portion for receiving elongated fasteners 120, 220. Slotted member 6 may also include complementary recesses or protrusions on one or both sides for interlocking with a complementary protrusion or recess of an adjacent spacer or top cap.

[0037] Slotted member 6 may be positioned over any particular spacer in a stacked set of spacers, for example over a first spacer and under a second spacer, over a second spacer and under a third spacer, over a third spacer and under a fourth spacer or over a fourth spacer. In this way, a height of slotted member 6 relative to a displayed electronic device 1 is variable and slotted member 6 may be positioned at an appropriate height for a particular displayed electronic device.

[0038] Additionally, an equal number of spacers may be used to secure adjacently displayed electronic devices, irrespective of the height at which the slotted member is positioned for a particular displayed electronic device. In other words, the same number of spacers is used for both taller and shorter electronic devices. This feature provides a pleasing aesthetic appearance, as all sets of stacked spacers associated with a number of displayed electronic devices along a length of grooved track may be of the same height.

[0039] First cap 100 and second cap 200 may be disposed over slotted member 6 as shown in FIG. 1. First cap 100 and second cap 200 may each comprise an annular disk having a through-hole 108, 208 extending through a thickness of caps 100, 200 for receiving an elongated fastener 120, 220.

[0040] First cap 100 and second cap 200 may also include a recesses 107, 207 disposed on a top surface thereof and sized so that optional fastener covers 110, 210 may be disposed within recesses 107, 207. Recesses 107, 207 may comprise, for example, a counterbore extending from a top surface of a cap to a depth corresponding to a height of a fastener cover 110, 210 and having a diameter such that fastener cover 110, 210 may seated in the counterbored portion of the cap.

[0041] Fastener covers 110, 210 may include a cup-shaped member 111, 211 having a through-hole 118, 218 for receiving elongated fasteners 120, 220 and a top portion 115, 215 for concealing an elongated fastener 120, 220 inserted in caps 100, 200. Top portion 115, 215 may be hinged or otherwise flexibly coupled to cup-shaped member 111, 211 so that top portion 115, 215 may be opened to inert or remove an elongated fastener 120, 220 and closed to conceal an elongated fastener 120, 220.

[0042] First and second elongated fasteners 120, 220 may comprise tamper proof fasteners which require a specialized tool for insertion or removal. Such tamper proof fasteners are well known and may, for example, be a fastener having a modified Allen-wrench opening for turning the fastener. First and second elongated fasteners 120, 220 may be inserted through respective fastener covers 110, 210, top caps 100, 200, slotted member 6, and sets of spacers 14, 24 and be engaged with respective retainers 11, 21 to secure a displayed electronic device 1 to support 2. First and second elongated fasteners 120, 220 may comprise threaded elongated fasteners having a threaded section along at least a portion of their length, for example screws or bolts. Quarter turn-type fasteners could also be used as elongated fasteners in a retainer device according to an embodiment of the invention.

[0043] A height of slotted member 6 can be adjusted over a wide range in increments according to a thickness of a spacer. Longer or shorter elongated fasteners may be used depending on a desired height of slotted member as appropriate for a particular application. Elongated fasteners for use with a retainer device according to an embodiment of the invention may be provided in lengths which increase in proportion to a thickness of a spacer. A length of an elongated fastener measured from a bottom portion of a lowest spacer downward may remain the same regardless of a total length of the elongated fastener in order to facilitate an engagement of a retainer with the grooved track as disclosed above.
