Abstract
An apparatus for displaying mobile phones and other hand-held devices comprising a clamping system, a retracting system, and a positioning system. The clamping system holds a hand-held device between two parts, which are fastened together by a fitting and a security screw having a head with a slot requiring a special key. The retracting system includes a retractable tethering cable wound on a spool. The positioning system includes a male component, which anchors the tethering cable to the fitting, and a female component, which is mounted on the retracting system. The tethering cable passes through the female component of the positioning system so that when the hand-held device is retracted, the male component of the positioning system is received by the female component thus assuring proper orientation of the hand-held device on display.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a security device for display of electronic hand held items and, in particular, to a device for marketing mobile phones which allows a potential customer to hold a phone at a limited distance from a display stand while automatically retracting and correctly positioning the hand held device on the display stand after its release.




2. Prior Art




With the growth of electronic devices in general and the ability to miniaturize in particular, light weight hand held mobile phones and similar devices have become pervasive. Items, such as cell phones, and hand held computers are sold to the public in a wide range of stores. To properly market such devices, consumers need to assure themselves that they can comfortable be used and manipulated by his/her hands In other words the consumer must be free to hold the device. But by allowing a consumer to inspect the item, the retailer is subjecting themselves to substantial loss through theft and other forms of shrinkage and breakage. It is equally important for marketing of cell phones and hand held computers that they be displayed in an upright position. Various attempts have been made to make retail displays which allow manipulation of displayed items while attempting to prevent theft.




For example U.S. Pat. No. 5,246,183 issued on Sep. 21, 1993 to Leyden discloses a tethering device for use in locations such as motel rooms that allows a remote control to be used but prevents its removal from the room. A spring in combination with a spool and cable allows a user to pull a hand-held remote control from a fixed position and automatically returns a the hand-held remote control back to its original location. It is not a display device for marketing. It does not guide the displayed item after release into a desired upright display position. There is simply no mechanism for turning the hand held remote upright.




While there have been a number of holders for hand held telephone, hand held computers and the like, they have been for the purpose of facilitating carrying and using the device rather than for security in display and marketing. There has been no mechanism as such for securing a mobile phone on a display but rather various devices that achieve the reverse. Such devices come with a variety of quick release mechanisms. See for example U.S. Pat. No. 5,903,645 issued on May 11, 1999 to Tsay; U.S. Pat. No. 5,555,302 issued on Sep. 10, 1996 to Wang.




While U.S. Pat. No. 6,002,921 issued on Dec. 14, 1999 to Pfahlert and Philips discloses a lockable cradle for holding a radiotelephone for use in vehicles it is released by a radio signal. This vehicle mounted device must be of a special construction and size to mate with the security system having grooves. It is neither designed for use in display systems, with existing devices, nor with a retracting and positioning system of the present invention.




SUMMARY OF THE INVENTION




The present invention for displaying mobile phones and other hand-held devices is comprised of three major components: a clamping system, a retracting system and a positioning system.




The clamping system of the present invention comprises two parts which are fastened together around a fitting attached to the end of a cord. The fitting may have a hole drilled through it to allow such a fastening. A security screw or bolt holds the two parts together with a key required to turn the head of the bolt or screw. The clamping system is locked onto the fitting and cannot be removed without the proper key. The clamping system has a lip on two opposite sides which prevents a person from removing the hand held device when the clamping system is fastened to the fitting and the hand held device is within the lips of the clamping system and attaches to a cable with a device also having a positioning guide to assure proper orientation of the hand-held device on display.




The retracting system comprises a coil spring, a spool and a cord mounted in a common decorative housing on which the mobile phone or the like rests. One end of the coil spring connects to the spool and the other end is attached to the housing. The cord is wrapped around the spool with one end attached to the spool and the other end attached to the mobile phone. When the mobile phone is moved from the housing the spool is turned and the coil spring is placed in tension. When the phone is released, the coil spring returns the spool to its original position.




The present invention has a positioning system to bring the cell phone back to its desired display position. The cord attached to the spool and the telephone is made from a relatively stiff material such as braided steel wire or cable. Thus, if the cord is pulled from the display stand and the cell phone is twisted or turned, the cord will develop a counter force to return the cell phone, upon release, to the original, upright position. To guide the hand held device into the proper position, the cord has on the end that emerges from the housing a first half of a positioning system which connects to the clamping system. The positioning system comprises interlocking or complementary male and female fittings. The fitting attached to the end of the cord may be either male or female with a corresponding mating fitting mounted on the housing. The cross-section of the male-female fitting pair may be of any shape other than circular with ovoid shapes preferred and cross-sectional ovoid shapes having guiding ribs contained within the ovoid female cross-section or on the exterior of the male ovoid cross-section most preferred. A non-circular shape, such as an ovoid, along with the ribs will assure that when the male fitting enters its female counterpart, the orientation of the fitting at the end of the cord will be the same as when the fitting, clamping system, or any device held within the clamping system, was pulled. The ribs assist with the guidance of the male fitting into the female fitting and assure that the fitting will return to its intended display orientation. Thus, the security display device of the present invention meets the needs of consumers and merchants by enabling a potential purchaser to conveniently examine a hand-held item such as a cell phone, conventional phone, camera, personal organizer and the like while preventing its theft and guaranteeing its return to a suitable display position when released after examination.

DETAILED DESCRIPTION OF THE INVENTION




FIG.


1


. shows a version of the retracting mechanism


100


of the present invention. A cord or security cable


101


is wrapped around a plastic double spool


102


having a channel


107


around which the cable


101


is wrapped and an adjacent channel


107




a


around which a constant force spring


106


is wrapped. The spool


102


is placed on an axle


110


which allows the spool


102


to rotate on its axis perpendicular to its circumference. The present invention contains a means for mounting the axle


110


to a housing plate


109


. A circular collar or ring


104


attached to one end of cable


101


is used to secure it to spool


102


while a non-circular collar


104




a,


preferably of ovoid cross-section is attached to the other end of the cable which is connected to coupling fitting


111


having male positioning component


112


. A channel


120


passes through positioning component


112


which contains cable


101


. Channel


120


has a generally circular cross-section in the general area at which cable


101


enters positioning component


112


but as it continues through, positioning component


112


has a non-circular cross-section


120




a


and altered dimensions to snugly retain non-circular collar


104




a


within channel


120


and prevent rotation of fitting


111


around cable


101


. The cable


101


is secured to the spool


102


by passing the cable


101


through an opening


103


in the spool


102


and inserting the cable


101


into a clip


105


located on the spool


102


. The clip secures to the cable so that when cable


101


is pulled ring


104


will not pass through clip


105


and will prevent any detachment of the cable


101


from the spool


102


.




A recoil or constant force spring


106


is connected to the spool


102


in spool channel


107




a


so as to not interfere with the cable


101


while the cable


101


is being released from or rewound onto the spool


102


. Constant force spring


106


is retained on spool


102


in channel


107




a


by means of a slot in the spool core. A length of the constant force spring


106


extends from the reel and coils around rod


122


which is connected to housing plate


109


The constant force spring


106


is arranged so that it is wound onto spool


102


as cable


101


is drawn off the spool, thus exerting a retracting force on cable


101


. The coil of constant force spring


106


is positioned between the walls of channel


107




a


of double spool


102


thereby holding spring


106


in place on rod


122


. The constant force spring


106


is arranged so that it is wound onto spool


102


from the coil on rod


122


as cable


101


is drawn off the spool, thus exerting a retracting force on cable


101


. When tension on cable


101


is released spring


106


retracts onto the coil on rod


122


thus rewinding cable


122


onto spool


102


.




When cable


101


is retracted by spring


106


after having been extended, male positioning component


112


enters a female positioning component or fitting


108


, of a male/female positioning fitting couple, that is mounted within flange


121


. The ovoid male positioning component


112


fits into opening


113


, having an ovoid cross-section, on the female positioning component. Flange


121


is attached to housing plate


109


and surrounds an opening in housing plate


121


through which cable


101


passes.




The coupling fitting


111


, having male positioning component


112


, also has incorporated into it the security claw linkage


114


. The security claw linkage


114


has a hole


115


drilled through it so as to allow a security screw


116


to fit through the linkage


114


.





FIG. 2

shows a version of a security claw


201


. The top section


202


connects or locks to the lower section


203


with the use of a security screw


116


which can be opened and closed with security key


216


. The top section


202


has attached to it a tab


204


has an opening that is sufficiently large to allow passage of the shaft but not the head of security screw


116


. The lower section


203


has a threaded tab


205


to receive safety screw


116


. To facilitate opening the security claw to insert or remove display merchandise it is preferred that only one tab be threaded. The tabs themselves may be threaded or, as shown for tab


205


, a threaded nut


206


can be attached to the tab. Both tabs


204


and


205


must be wide enough to allow the security screw


116


to be placed through it so that the security claw


201


is securely fastened to the security claw linkage


114


. Security key


216


has ends


218


that are shaped to fit into a non-conventional opening or slot


220


in the head of security screw


116


. Non-conventional openings or slots


220


on security screw


116


which security key


216


is shaped to fit might for example have star, cruciform, circular or non-circular cross-sections and also have concavities and convexities within the opening


220


. Top section


202


and lower section


203


together comprise a cradle to contain a hand-held device such as a cell phone. Each section may be formed as a complete unit from metal, plastic or any other strong rigid material capable of securely containing a hand held device or as in the version depicted in

to contain a device on three sides. As seen in

FIG. 2A

bottom


203




b


extends to form a lip


224


to enclose a device on a fourth side. Lip


224


may extend to brace


223


and be connected to it if necessary to securely enclose a device. Each leg of U-shaped brace


223


is connected to a separate side


203




a


forming a bridge over bottom


203




b


to secure a device on a sixth side.





FIG. 3

is a back view of the clamping device of

FIG. 2

showing the assembly of the clamping device to a version of a coupling fitting


111


having an ovoid version of a male component


112


of the male/female positioning fitting. Security screw


116


is inserted through the unthreaded opening in tab


204


on the back of security claw


201


, through the opening


115


in the security claw linkage


114


of coupling fitting


111


, and into the opening of threaded tab


205


and tightened with security key


218


shown in FIG.


2


. As shown in

FIG. 3

, coupling fitting


111


is generally arranged so that cable


101


extends from the back of security claw


201


although in other versions fitting


111


may be modified, by means known in the art, to permit security cable


101


to conveniently extend from the side of security claw


201


.





FIG. 4

depicts the version of security claw


201


and coupling fitting


111


shown in

FIG. 3

as fully assembled and secured with security screw


116


. In practice, a hand-held device such as a cell phone is inserted into the claw


201


before it is fully assembled and coupled to security cable


101


. For example an appropriately shaped cell phone is inserted into lower section


203


so that the lower part of the phone fits under brace


223


with the face of the phone facing away from bottom


203




b


. As shown in

FIG. 3

coupling fitting


111


is inserted between top section


202


and bottom section


203


. Top section


202


is then slipped over the top of the cell phone and coupled to bottom section


203


through coupling fitting


111


by means of security screw


116


which is securely tightened into threaded tab


205


. As will be apparent to those skilled in the art the form of upper component


202


and lower component


203


of security claw


201


may be varied depending on the shape and dimensions of the cell phone or other hand-held device to be securely held therein. Regardless of form each security claw will comprise an upper and a lower component having tabs


204


and


205


so that the upper and lower component of the security claw can be coupled by means of coupling fitting


111


and securely held by security screw


116


as illustrated by the example depicted in FIG.


4


.




The retracting system to which cable


101


is attached is typically securely mounted on a display unit. When the displayed cell phone is examined it is pulled away from the retracting unit


100


, but securely held by cable


101


attached to security claw


201


. Upon release the retracting force developed by constant force spring


106


draws the cable back onto spool


102


causing the cell phone to be pulled towards its initial display position. Due to non-circular collar


104




a


held in non-circular channel


120




a


and the stiffness the cell phone coupled with fitting


111


cannot freely rotate around tethering cable


101


and will also tend to return to its initial rotational orientation upon release. A non-circular, male positioning component such as component


112


of

FIG. 1

having an ovoid cross-section is used since it must be properly oriented to enter a corresponding non-circular, female positioning component such as component


108


having an opening


113


with an ovoid cross-section thus insuring that the cell phone returns to its original display position.




Another version of a female positioning component to receive an ovoid cross-section male positioning component is seen in FIG.


5


. Female positioning component


500


generally comprises a tubular structure having walls


501


and


502


enclosing a lumen


513


. Rounded rails


503


,


504


,


505


,


506


,


507


and


508


traverse the length of the interior surface of walls


501


and


502


facing lumen


513


and are substantially parallel and guide male ovoid cross-section positioning component into lumen


513


. Generally, the rounded rails are arranged along the length of lumen


513


so that their rounded surfaces come into generally tangential contact with the sides of the male positioning component having an ovoid cross-section. Female positioning components having rails are preferred as this arrangement reduces friction relative to the female positioning component


108


that has a completely ovoid cross-section thereby facilitating the rapid return of the secured hand-held unit to its initial display position. In another preferred version of female positioning component


500


the rounded rails are slightly recessed from the entrance to lumen


513


to facilitate slight rotation to the initial display position in the event that cable


101


is slightly twisted. Female positioning component


500


is generally formed from two identical segments


501


and


502


, that are joined at seams


511


and


512


generally by press fitting into flange


121


of FIG.


1


. Notches


509


and


510


facilitate press fitting into flange


121


. The positioning and coupling fittings of the present invention may be formed or processed from any rigid material known in the art that may be machined, molded or otherwise formed into a desired shape by means commonly known and practiced in the art. Relatively tough, rigid plastics that may be machined and press fit such as machinable grades of polyvinylchloride (PVC) and other machinable plastics are preferred. Each positioning component may be formed as a single unit or in two or more units that are joined by press fitting, welding and adhesive means as commonly known and practiced in the art. Combinations of materials such as metal and plastic, different metals and different plastics may be used for the female and male positioning components of the present invention.




The apparatus for secure display of hand held items of the present invention may be used singly or in multiple arrays on display structures to securely and attractively display such items for examination by consumers.




It is understood that the present embodiments described above are to be considered as illustrative and not restrictive. It will be obvious to those skilled in the art to make various changes, alterations and modifications to the invention described herein. To the extent that these variations, modifications and alterations depart from the scope and spirit of the appended claims, they are intended to be encompassed therein.
