This invention relates in general to security and anti-theft devices, and more particularly, to a security device for a hinged electronic product or device to prevent theft of such item.
In order to deter and prevent the theft of various hinged electronic items such as laptop computers and portable DVD players and the like from offices, houses and other establishments, various security devices and systems have been developed. One known security device comprises a bracket assembly that captures the laptop about its hinge and is fixedly attached to a table or other object to prevent movement of the hinged device. It is also known to use a cable that encircles the hinge in place of the brackets. While such devices may work, the brackets and cable are often cumbersome and are not aesthetically pleasing (e.g., for use in store displays). Furthermore, use of the bracket assemblies or known cables substantially prevents movement of the laptop. Accordingly, such devices are not favored by retailers and other business establishments who desire the product to be picked up and examined by potential purchasers, in as close to actual use conditions as possible.
It is also known to use a detector that is screwed into the video port, wherein an alarm goes off if anyone tries to unscrew the detector. However, it is desired to eliminate the need for having to screw a detector into the video port. Yet another known device utilized an electronic sensor that would go off if one tried to remove the cable from the hinged device. While these systems may work, they were not well received by the business community because they lacked a mechanical tether.
Additionally, it has been known to use a KENSINGTONĀ® port that utilizes a security cable having a loop at one end such that, after the cable is wrapped about an object, the other end of the cable may pass through the loop and be attached to the KENSINGTON port on the computer. However, such systems permit the computers to be stolen by breaking off part of the computer about the KENSINGTON port, thereby leaving the laptop housing damaged, but not affecting the operability of the computer.
Therefore, there is a need to produce a security device capable of protecting against theft of a hinged electronic device, while permitting movement and use of the electronic device, and which addresses the problems with the prior systems and devices, without damaging the hinged device.
The present invention is an improvement over the prior security systems in the way that the security device protects a hinged product such as a laptop or portable DVD player. The security device of the present invention comprises a band or plate having a height that permits it to extend through the open area about the hinge of a hinged electronic product (i.e., the area between the screen and the body). Anchor assemblies fixed or attached to both ends of the plate are sized so that they (and thus the plate) may not be pulled through the hinge. In particular, a first anchor assembly may include a bottom and top half that collectively include a male member and a corresponding female member that can extend through a slot on the end of the plate. Once the halves of the first anchor assembly are attached together (e.g., by ultrasonic welding), the first anchor assembly is thus fixed in place relative to the plate.
A hole extending through the plate is sized to receive the elongated body of a fastener for connecting the plate to the second anchor assembly. The second anchor assembly may include a base and a lid assembly that may be attached together by a pair of fasteners and that include a slot for receiving the plate. In one embodiment, the lid assembly includes a pair of holes that have an upper portion sized to permit the head of the fastener to be recessed within the bottom of the lid assembly. The lower portion is sized so that the fastener head may not pass therethrough. Accordingly, once the plate is inserted into the corresponding slot of the second anchor assembly, the plate will cover and prevent access to the fastener heads.
A tether extends from the second anchor assembly to securely attach the security device and hinged electronic product to an object, thereby allowing the hinged electronic product to be securely moved a limited distance. The tether may comprise one or more wires for electronically attaching the security device to an alarm system to, among other things, set off an alarm when the tether is cut.
In order to detect the presence of the plate, the second anchor assembly may include a lever switch so that insertion of the plate into the slot of the second anchor assembly depresses the lever to complete an electrical circuit and arm the device. Subsequent attempted removal of the plate acts to open the circuit and activate the alarm.
The security device may also include a sensor attachable to the hinged electronic product to detect attempted removal of the security device from the hinged product. In one embodiment, the sensor comprises a sensor housing having a button extending outwardly from its bottom and that is depressed when attached to the surface of the hinged product to complete an electrical circuit. The bottom of the sensor includes an adhesive sheet to adhere to the surface of the hinged product. A release liner may be placed over the adhesive sheet when not in use to protect the adhesive sheet. In operation, depression of the button when the sensor is placed onto the surface of the hinged electronic product acts to close the electrical circuit. An indicator (e.g., an LED) associated with the sensor may then indicate that the sensor is armed. Attempted removal of the security device and/or the sensor that causes the sensor to be removed from the surface of the hinged product will open the circuit and activate an alarm in the form of a visual (e.g., an LED) and/or audio response.
A circuit board may be located inside the anchor assembly to assist in monitoring the status of the security device. In one embodiment, the circuit board is an intelligent device that may be connected to and monitor resistance of the lasso assembly or cable to determine when it is tampered with or cut. A LED on or associated with the lasso may be operatively connected to the circuit board to flicker, blink, indicate or otherwise indicate tampering with the lasso assembly.
The second anchor assembly may also include at least one electrical circuit for detecting the attempted removal or tampering with the security device. In one embodiment, the plate may include a pair of electrical contacts that are connected to an alarm system through filaments and corresponding contacts. When the fastener is inserted through the hole in the plate to attach the plate to the second anchor assembly, the head of the fastener or a washer engages the pair of electrical contacts to form an electrical circuit. Removal or attempted removal of the fastener re-opens or breaks the electrical path between the pair of contacts, which can be detected by a security or alarm system. The aforementioned electrical circuit or another electrical circuit may also be operatively attached to an indicator such as a light emissive device (e.g., an LED) to indicate when the security device is armed. The plate may also include filaments that detect when an attempt is made to cut the plate and trigger a visible and/or audible alarm.
In an alternate embodiment, the plate may include raised portions that engage brush-type contacts located in the second anchor assembly when the plate is inserted into the second anchor assembly to complete an electrical circuit for indicating that the system is armed and detecting the removal of the plate from the second anchor assembly.
It is therefore an object of the present invention to provide a new and improved security device for use in the prevention of theft.
Another object of the present invention is to provide a new and improved security device that permits movement of a hinged product.
It is yet another object of the present invention to produce a security device that is economical and easy to manufacture and use.
Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like reference numerals refer to like parts.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail several specific embodiments, with the understanding that the present disclosure is to be considered merely an exemplification of the principles of the invention and the application is limited only to the appended claims.
Referring now to the drawings, and particularly to
The first anchor assembly 12 may be made out of a variety of materials including, but not limited to, plastic. A suitable material is a thermoplastic material such as Acrylonitrile-butadine-styrene (ABS) to provide suitable environmental ruggedness at a relatively low cost. In order to facilitate its manufacturing and assembly, the first anchor assembly 12 may be made of two halves. Referring to
The top half 30 includes a male member or wall 32 extending upward that is sized to fit within the cavity 24 of the first anchor assembly 20 so that the bottom and top halves 20, 30 may integrally form the first anchor assembly 12 and be held in place relative to the plate 16. The halves may also include one or more ribs 34 to enhance the rigidity and strength of the assembly. Referring to

Once placed together, the insert 54 and lid 52 may be fixed together using an ultrasonic weld or other known means to securely form a lid assembly 70, as shown in
The base 50, lid assembly 70 and plate 16 may be connected together through a plurality of fasteners. One embodiment, as shown in
Ribs 84, as shown in
In addition or alternatively, the security device may include a lever switch 100 operatively attached to an alarm system 19 through one or more wires 102, as shown in
The security device may also include a sensor 200 that may be attached to the hinged electronic product to detect the attempted removal of the security device from the hinged product, as shown in
The security device may include a circuit board located within the anchor assembly. In a preferred embodiment, the circuit board is an intelligent device to monitor the status of the security device.
In order to increase the security of the second anchor assembly, the holes 67 in the lid 52 and may be sized so that their diameter is larger than the diameter of the head of the screws 72 to permit the heads of screws 72 to pass therethrough. Referring to the embodiments shown in
Referring now to
Referring to
The plate 16 may also include a filament 130 that is connected to a pair of contacts 132 through a pair of filaments or wires 134. In operation, when the plate is inserted into the second anchor assembly 14, the contacts 132 coact with contacts 136 to form an electrical circuit. When used with a plastic first anchor assembly 12, when the anchor assembly 12 is welded together, the halves of the bottom half of the first anchor assembly 12 hooks onto the filament 130. If the first anchor assembly is broken, the filament 130 will break so as to break the circuit, thereby setting off or activating an alarm.
Referring now to
While the plate is shown as having a contiguous end, it is appreciated that the plate may include a slot defining a pair of tines to permit the plate to accept a post of a hinged product (e.g., a tablet computer). Each of the tines may include a hole for accepting a screw or other fastener to attach the plate to the second anchor assembly. While a plate is shown and disclosed, it is appreciated that other connectors may be used to extend through the hinge and connect to the anchor assemblies. Such connectors may include, but not limited to, a cable may be used with the present invention to extend through the hinge and connect to the anchor assemblies.
It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention, but it is understood that this application is limited only by the scope of the appended claims.
This application claims the benefit of U.S. provisional patent application Ser. No. 60/824,301, filed Sep. 1, 2006.
