the security on display system of the present invention , for use with retail items such as cameras , video camera recorders and the like is shown in fig1 and is generally referred to by the reference numeral 10 . in this embodiment , a video camera recorder 11 is shown while be examined by a potential customer . the camera 11 has been displayed on display counter 13 in a typical retail establishment . mounted on the display counter 13 is a pedestal 15 for holding the camera 11 when it is on display . camera 11 has a mounting device 17 attached to it such that the mounting device 17 fits into pedestal 15 . thus , when the potential customer wishes to inspect the camera 11 , it is only necessary to lift camera 11 out of pedestal 15 . the pedestal 15 is attached using a base 19 and fasteners 20 to the display counter 13 . base 19 is sized to adequately support the weight and balance of various sized retail items . turning now to fig2 it can be seen that holes 21 are provided in the base 19 of pedestal 15 so that fasteners 20 can be attached through the table 13 and secured from the underside of table 13 to prevent tampering with the pedestal 15 and base 19 . mounting device 17 is attached to camera 11 or other retail item by a threaded bolt 23 which extends out of the mounting device 17 . also extending out from the mounting device is an alignment pin 25 which interacts with alignment holes which are typically found on cameras and the like for mounting tripods . as will be apparent herein below , mounting pin 25 prevents rotation of the mounting device 17 to thereby prevent undesired removal of the device 17 from the camera 11 . the camera engaging end of mounting device 17 also includes a slot 27 to provide for attachment of a security device . shown in fig2 is an elongated cable 29 which fits easily in slot 27 and which has an enlarged spherical locking element or cable ball 31 on its terminal end . the space between the bolt 23 and the slot 27 is sufficient to accommodate the enlarged cable ball 31 and prevent pulling cable 29 away from mounting device 17 . the other end of elongated cable 29 is attached to a locking security device 30 which is mounted on the underside 14 of display table 13 . particularly preferred is the security device described in previously identified u . s . pat . no . 4 , 598 , 827 , the disclosure of which is incorporated herein by reference . in that system as shown in fig1 herein , the end of cable 29 away from the camera 11 is secured in a locking device 30 where it cannot be removed without having access to the lock . cable 29 extends through the display table 13 and may optionally be enclosed in a wire loom sheath 33 or other tube which is attractive . the sheath 33 should not detract from the flexibility of the cable , but permit the camera 11 to be examined with relatively complete freedom by the customer . also contained in sheath 33 is a second cable 35 . cable 35 forms part of an electronic security device in which a switching device 37 is attached to the camera 11 as shown in fig1 . the switching device 37 is electronically connected to a power source at one end . the power source is contained in an alarm system 36 shown in fig1 to be attached to the display counter support surface 14 and is inaccessible to the customer . in one embodiment , the alarm system 36 is of the type described in previously mentioned u . s . pat . no . 4 , 620 , 182 . the disclosure of that patent is also incorporated herein by reference . in that system , the cable 35 contains a pair of conductive elements in a coaxial cable , such as columbia flex foam 1359 , manufactured by columbia electronic cables of pawtucket , rhode island . as is described in u . s . pat . no . 4 , 620 , 182 , any attempt to cut or otherwise remove cable 35 or switching device 37 causes completion of an electronic circuit which then activates an alarm . the switching device 37 is attached by an adhesive to the camera 11 and will activate the alarm if the adhesive is removed while the alarm system is turned on . typically , cameras on display are used only for display , and purchases are made of retail items from inventory and are still in the manufacturer &# 39 ; s shipping and display cartons . however , if the camera 11 is to be sold , switch 37 can be disengaged by store personnel after turning off the alarm system 36 . it can be seen that a security system is provided which gives mechanical security through cable 29 and electronic security and alarm through cable 35 . at the same time , the potential customer has complete freedom to examine the retail item at his or her leisure . the mounting device 17 of the present invention includes several features which add to the security of the system . turning now to fig3 the relationship between the camera 11 and the pedestal 15 can be seen . the mounting device 17 is attached to the former and rests comfortably in the latter . the mounting device 17 is attached to camera 11 by threaded bolt 23 which can be accessed through the center hole 39 in mounting device 17 . the threaded bolt 23 screws into threaded mounting hole 41 in camera 11 . typically , cameras and other video devices contain holes of this type for mounting tripods and other attachments to the camera . threads on bolt 23 are sized to accommodate these fittings . cameras also have alignment holes 43 and it is intended that the alignment pin 25 of the mounting device 17 extend into hole 43 . thus , pin 25 and hole 43 cooperatively prevent turning the mounting device 17 with respect to the camera 11 , thereby preventing it from simply being unscrewed by someone wishing to defeat the security of the system . when the mounting device 17 is attached to camera 11 , the head 47 of bolt 23 pulls the face 45 of camera 11 up against flange 49 . flange 49 is the camera engaging end of mounting device 17 and includes the previously described slot 27 . elongated cable 29 rests in slot 27 , with a slight amount of clearance 27a , but not enough clearance to permit the enlarged spherical locking ball 31 from passing between the bottom face 45 of camera 11 and the flange 49 into which slot 27 has been cut . accordingly , as long as bolt 23 is tightened into fitted mounting hole 41 , cable 29 remains firmly and securely attached to camera 11 . when the object is on display , the top portion of pedestal 15 provides a shoulder 51 which supports the flange 49 of mounting device 17 . the depth of mounting device 17 is sufficient to prevent the camera from inadvertently falling or being dislodged if it were to be bumped by an inattentive potential consumer . yet it is easy to remove the camera 11 and mounting device 17 from the pedestal 15 . mounting device 17 also includes a central shaft portion 53 which connects the threaded end of bolt 23 to the bolt head 47 . central shaft 53 passes through bore 55 in the flange 49 and is loosely fitted so that the larger threads 23 can be put through flange 49 for engagement into camera mounting hole 41 . as long as the threaded bolt is not unscrewed , it will remain secure in threaded mounting hole 41 and the mounting device 17 and any security cables 29 and the like will remain in tact . however , at times when it is desirable by the retail establishment to change cameras 11 , the threaded bolt 23 can be removed from the camera . an &# 34 ; o - ring &# 34 ;, not shown , can be used to prevent the threaded bolt 23 from falling through bore 55 , and potentially being lost or misplaced . of primary importance in any security device is the requirement that the mounting device or other security means be as tamper proof as possible when it is attached to the retail item being secured and displayed . in a preferred embodiment , the threaded bolt 23 is attached to the camera 11 in threaded mounting hole 41 by rotating the bolt head 47 and screwing the mounting device onto the camera face 45 as it moves from the dot dash location shown by reference numeral 47a to the firmly attached position 47 in fig3 . the fastener preferably is operable only using a non - conventional attachment means . in order to prevent disassemblement by a potential shoplifter , such as by the use of a screw driver or other tool , bolt head 47 contains a hexagonal bore 59 of the type conventionally known as an allen wrench slot or bore . also contained in bore 59 is an axially centered cylindrical pin 61 whose terminal end 61a is coplanar with the terminal end 47b of bolt head 47 . thus , a typical allen wrench cannot be inserted into bore 59 to engage with the polygonal surfaces . other non - conventional fasteners such as an off - sized allen wrench and bore combinations , or unusual screw heads with special screw drivers , can be used . turning now to fig4 the preferred special tool 63 is shown ready for use with bolt 47 . special locking tool 63 includes an allen wrench end 65 , hexagonal in shape to correspond with the bore 59 of bolt head 47 . the tool 63 also includes a cylindrical hole 67 which is sized to mate with cylindrical pin 61 . thus , in order to insert the tool 63 into the bolt head 47 , it is necessary to align the hexagonal bore 59 with the hexagonal shaft head 65 . it is also necessary to align cylindrical pin 61 with hole 67 . while no security system is one hundred percent secure , it is unlikely that the any shoplifter will carry a tool such as wrench 63 since these are not commercially available and since both bore 59 and shaft 65 can be of an unusual size and configuration . accordingly , removal of the bolts 23 from the camera 11 to detach mounting device 17 can only be done by the retailer personnel . in order to demonstrate the efficacy of the present invention , a display of video cameras and video recorders was fitted with the present invention . not only were there no thefts or disappearances of the equipment , sales increased by twenty - two percent ( 22 %) over a comparable time period . store personnel stated that the increase in sales was due to increased impulse buying when customers were able to handle the equipment . while the invention is susceptible to various modifications and alternative forms , a specific embodiment has been shown and described herein . it is to be understood , however , that it is not intended to limit the invention to the particular embodiments disclosed herein . on the contrary , the intention is to cover all modifications , equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims .
