## Background
FIELD OF THE INVENTION
This invention generally relates to an inventory display lock, and more particularly to an inventory display lock for use with display hooks that are attached to a merchandise display for holding and displaying merchandise at a retail establishment.
BACKGROUND OF THE INVENTION
There are a variety of different types of display hooks that are presently in wide use. One type of display hook is a “scanner hook” of the type disclosed in U.S. Pat. No. 4,452,360 to Barnes. The scanner hook includes a lower horizontally extending hanger bar for supporting merchandise and an upper parallel bar for supporting a label that includes a price tag which may be “read” by an electronic scanning wand.
Unfortunately, these display hooks by themselves provided little or no theft deterrence to shoplifters. Particularly, shoplifters will steal product by a method know as sweeping. The shoplifter will “sweep” the entire product supported by the lower hanger bar from the display hook in a single motion into a container such as a purse or bag. This method of shoplifting occurs very quickly and results in a significant loss of product. Security display locks have been developed to prevent sweeping by securing or locking the merchandise on the display hook. Such display locks include U.S. Pat. No. 6,957,555 to Nagel et al.; U.S. Pat. No. 6,393,877 to Church; U.S. Pat. No. 5,275,027 to Eklof et al.; U.S. Pat. No. 5,027,622 to Hatch et al.; U.S. Pat. No. 7,197,902 to Barkdoll; and U.S. Pat. No. 7,743,931 to Barkdoll. The present invention relates to improvements in display locks as it relates to theft prevention, reliability, adaptability, practicality, ease-of-use, and/or cost effectiveness.

DETAILED DESCRIPTION OF THE INVENTION
An exemplary embodiment of a display lock system 100 in accordance with the invention is illustrated in FIG. 1. The display lock system 100 is used to securely display merchandise 102 for sale to customers in a retail establishment. The display lock system 100 allows for selective removal of the merchandise 102 therefrom. This configuration prevents sweeping as discussed above.
The display lock system 100 includes a vertical support in the form of a pegboard 106 having numerous apertures 108, in the illustrated embodiment. It is also noted that, while the current display lock system 100 uses a pegboard, other retail fixtures can be used with the current display lock system. More particularly, the display hooks 110, which are illustrated as scanning style hooks for pegboards, could be attached to slat walls or other types of vertical support structures. A display hook 110 for carrying the merchandise 102 is mounted to and extends outward from a front face of the pegboard 106. The display hook 110 has a rear mount 112 adapted to selectively attach the display hook 110 to the apertures 108 of the pegboard 106. Further, the display hooks 110 could be permanently attached to the vertical support such as being welded to the vertical support or to a shelf.
The display hook 110 is a scan style retail hook that includes a top bar 114 and a bottom bar 116 extending in a forward direction outward from the rear mount 112. The top bar 114 is vertically displaced above and generally parallel to the bottom bar 116. Typically, but not required, the top and bottom bars 114, 116 are formed from a single continuous piece of metal rod or wire that is bent into a generally U-shaped member.
The front end of the top bar 114 terminates in a stop 118 in the form of a cross-wire configured for attaching a sign holder. In the illustrated embodiment, the stop 28 is a laterally extending piece of rod that is perpendicular to the top and bottom bars 114, 116. However, in other alternative embodiments the stop could be a bend in the free end of the top bar 114. Other forms of a stop could be provided or merely a sign holder could be provided that is permanently attached to the top bar 114.
The front or distal end of the bottom bar 116 terminates in a bent free end 120. The bent free end 120 extends upwards towards the top bar 114. The bottom bar 116 carries the displayed merchandise 102 and the bent free end 120 helps retain merchandise 102 on the bottom bar 116 when merchandise is allowed to be removed from the display lock system 100.
The display lock system 100 includes a display lock 130 attached to the display hook 110 to inhibit removal of merchandise 102 from the bottom bar 116. The display lock 130 is illustrated in a closed state wherein the display lock 130 prevents removal of the merchandise 102 from the bottom bar 116. The display lock system 100 is illustrated in FIG. 2 in an open state such that the display lock 130 does not inhibit removal of the merchandise 102 from the bottom bar 116.
With reference to FIGS. 3 and 4, the display lock 130 generally includes a lock body 132 defining a mounting channel 134 and an attachment pin 136 for securing the lock body to the display hook 110 and particularly to the top bar 114 of the display hook 110. The lock body 132 will saddle top bar 114 when mounted. The mounting channel 134 is sized to receive the top bar 114 therein. The top bar 114 includes an aperture 138 (see also FIG. 5) formed in a coined/flattened portion through which the attachment pin 136 extends to fixably attach the lock body 132 to the top bar 114 with the top bar 114 extending through the mounting channel 134. The mounting channel 134 defines a bottom 140 from which the attachment pin 136 is spaced to allow a portion of the top bar 114 to be positioned therein. The attachment pin 136 extends entirely through the mounting channel 134 from one side to the other.
The display lock 130 includes a lock bar 142 rotatably coupled to the lock body 132 for rotation about a lock bar axis 144 relative to the lock body 132. This configuration allows the lock bar 142 to transition between the closed state and the open state discussed previously to selectively allow removal of merchandise 102. The lock bar 142 is generally U-shaped and defines a lock bar aperture 146 configured to receive the distal bent free end 120 of the bottom bar 116 of the display hook 110 therethrough in a direction that is substantially perpendicular to the lock bar axis 144. When the display lock 130 is in the closed state (see FIG. 1), the display lock 130 surrounds the distal end of the bottom bar 116 to prevent removal of merchandise 102 therefrom.
With additional reference to FIGS. 7 and 8, the lock body 132 is axially positioned between distal ends 148, 149 of first and second leg portions 150, 151. Distal end 148 is formed from a separate component 184 as the rest of the lock bar 142 to assist in assembly of the display lock 130.
The attachment pin 136 of the illustrated embodiment is generally in the form of a screw that extends through an aperture 150 in distal end 149 and then through an aperture 156 in the lock body 132 and then finally through an aperture 158 in the other distal end 148. The first end of the attachment pin has an enlarged head portion 160 and an opposed threaded end 160. The enlarged head portion 160 is larger in dimension than aperture 154 through distal end 149 to prevent complete passage of the attachment pin 136 therethrough. The threaded end 162 mates with a lock nut 164 to secure the attachment pin 136 in distal ends 148, 149 and lock body 132 and secure the components in an assembled state.
As illustrated in FIG. 8, the attachment pin includes a central portion 166 axially positioned between the threaded end 162 and enlarged head portion 160. The central portion 166 includes two opposed flats 167, 168 that prevent rotation of the attachment pin 136 relative to the lock body 132. As illustrated in FIG. 7, the lock body 132 includes corresponding flats 169, 170 forming part of the boundary of the aperture 156 therethrough. In some embodiments, the aperture through the top bar 114 has similar flats to prevent rotation of the attachment pin 136 relative thereto. The attachment pin 136 extends through the first and second leg portions 150, 151 and is coaxial with the lock bar axis 144 in the illustrated embodiment. The attachment pin 136 maintains the lock body 132 in a sandwiched relationship between the distal ends 148, 149 of the lock bar 142.
The lock body 132 includes a recessed end 170 that receives an axially extending cylindrical hub 172 when the display lock 130 is assembled. The interaction between the hub 172 and the shoulder 174 provided by the recessed end 170 permits relative rotation between the lock body and the distal end 148. The opposed end of the lock body 132 includes a hub 176 that is axially received in a recess 178 that also provides a shoulder 180. The interaction of this hub 176 with shoulder 180 further supports the lock bar 142 relative to the lock body 132 for rotational motion therebetween. It should be noted that the recesses and hubs and recess of the lock body could be provided by the lock bar and similarly the hubs and recess of the lock bar could be provided by the lock body. Further, all recesses could be provided by either the lock bar or lock body and all hubs could be provided by the lock bar or lock body where appropriate.
As noted above, distal end 148 is formed from a separate component 184 from the rest of lock bar 142. The separate component and the rest of the lock bar 142 have a mating interface 182 that is generally a dovetail arrangement. The mating interface 182 is configured to allow the separate component 184 to slide axially parallel to the rotational lock bar axis 144 to assist in assembly of the display lock 130. It should be noted that the hubbed arrangement discussed above is not necessary, however it is beneficial to maintain engagement of the lock body 132 relative to the lock bar 142 while mounting the display lock 130 to the top bar 114. The mating relationship prevents the lock body 132 from falling out from between the distal ends 148, 149 when the attachment pin 136 is moved axially out of the apertures 154, 156, 158 discussed above.
With primary reference to FIGS. 5 and 9, the display lock 130 includes a lock arrangement 200 interposed between the lock body 132 and the lock bar 142. The lock arrangement 200 can be manipulated between a locked state (FIG. 5) and an unlocked state (FIG. 9). In the locked state, angular rotation of the lock bar 142 relative to the lock body 132 is prevented. Therefore, the lock arrangement prevents transition of the display lock 130 from the closed state to the open state (see FIGS. 1 and 2 discussed above).
The lock arrangement 200 generally includes at least one lock pin and in the illustrated embodiment a pair of lock pins 202 extending across a shear interface 204 positioned axially between the lock body 132 and the lock bar 142. More particularly, the shear interface 204 is positioned between distal end 206 of hub 176 and inner face 208 of distal end 149. The distal end 206 and the face thereof axially faces the inner face 208 of distal end 149 of leg portion 151.
In the locked state, the lock pins 202 engage both the lock body 132 and the lock bar 142 to prevent rotation of the lock bar 142 relative to the lock body 132 about the lock bar axis 144. In the unlocked state, the lock pins 202 do not extend across the shear interface 204 and do not engage the lock bar 142, and particularly the distal end 149 thereof. Because the lock pins 202 do not engage the lock bar 142, rotational motion therebetween is permitted.
The lock pins 202 are axially slideable relative to the lock bar 142 and lock body 132 between the locked and unlocked states. A key 210 can cooperate with the lock pins 202 to transition the lock pins to the unlocked state. The key 210 will engage distal ends 212 of the lock pins 202 and push the lock pins 202 past the shear interface 204. With the distal ends 212 pushed past the shear interface 204, the lock bar 142 is permitted to rotate relative to the lock body 132 at the rotation interface between the hub 176 and shoulder 180.
With additional reference to FIG. 7, the lock pins 202 are slideably carried in a locked pin channels 214 formed in the lock body 132 between the locked and unlocked states (see FIGS. 5 and 9). Return spring members 216 may also be carried in the lock pin channels 214 to bias the lock pins 202 towards the locked state and particularly biasing the lock pins 202 axially out of the lock pin channels 214 such that the lock pins 202 are positioned across the shear interface 204. The lock pins 202 and springs 214 act as plungers.
With additional reference to FIG. 10, the distal end 149 has an abutment plate that defines a pair of key slots 218, 220 through which the key extends to unlock the display lock. At one end, key slots 218, 220 include a pin retaining pocket 222 that the lock pins 202 extend into in the closed state and are removed from in the open state. The pin retaining pockets 222 are configured such that the lock pin engages the portion of the lock bar 142 forming the pin retaining pockets in the locked state to prevent rotation of the lock pins 202 relative to the distal end 149 of the lock bar 142 when the lock pins 202 are positioned within the pin retaining pockets 222. The key slots 218, 220 are generally arc shaped and are configured to receive a key therein in a direction extending generally parallel to the longitudinal axis of the lock pins 202. This is also generally parallel to lock bar axis 146. The pin retaining pockets 222 in the illustrated embodiment are formed at the ends of the key slots 218, 220. The lock pins 202 engage a first set of the pin retaining pockets 222 when the lock bar is in the open state.
The abutment plate can define arcuate channels in which the distal end 212 of the lock pins 202 can be positioned in the unlocked state while rotating the lock bar 142 relative to the lock body 132. The lock pins 202 need not be entirely recessed within lock pin channels 214 of the lock body, as illustrated in FIG. 9.
In the open state, the key 210 can be removed from the display lock 130 and the lock pins 202 can be inserted into the pin retaining pockets 224 at the opposite ends of the key slots 218, 220. In this configuration, the lock pins 202 are used to maintain the lock bar 142 in the open state such that the user can load merchandise on to the bottom bar 116 with the lock bar 142 maintained in a location where it will not interfere with loading the bottom bar 116 with merchandise 102.
The illustrated embodiment uses two fixed configurations where the lock bar 142 is either in the closed state (see FIG. 1) or the open state (see FIG. 2). Other designs could have the lock pins 202 cooperate with the distal end 149 of lock bar 142 in the open state such that the engagement therebetween is sufficient to maintain the lock bar 142 in the released state but not so strong that the user cannot merely transition lock bar 142 to the lock state when finished. Such an arrangement would be configured such that the lock pin 202 would drop into a minimally recessed cavity of the lock bar 142 rather than the deeper slots that are currently illustrated. This would only provide limited resistance to transitioning the lock bar 142 to the secured state from the released state.
The lock bar 142 can include an angular key orientation slot 226 in which a radially extending projection of the key 210 can extend. This allows the manufacturer to modify the angular location of the angular key orientation slot 226 relative to the rest of the key slots 218, 220 for providing different keyed arrangements between the key 210 and the display lock 130.
As illustrated in FIG. 5, the enlarged head portion 160 of the attachment pin 136 includes notched portions 232, 234 in the outer periphery thereof in which the distal ends 212 of the lock pins 202 extend in the locked state. This engagement between lock pin 202 and the enlarged head portion 160 further assists in preventing rotation of the lock bar 142 relative to the lock body 132 in the locked state.
The key slots 218, 220 are configured in size to receive corresponding shaped and sized end portion of the key 210. The key slots 218, 220 are therefore axially aligned with the lock pin channels 214 such that the distal end of the key 210 can engage the distal end 212 of the lock pins 202.
The distal end 149 of lock bar 142 defines a key receiving aperture configured to receive the key 218 for engagement of the key 218 with the lock pins 202. The key 210 includes a central aperture. The central aperture of the key 210 receives the enlarged head portion 160 of the attachment pin 136 when the key 210 is inserted into the key receiving aperture 238. The distal end 149 and the enlarged head 160 define a channel therebetween that forms a portion of the key receiving aperture 238.
Additionally, due to the inclusion of the key projection 228 on the key, the display lock 130 can be configured such that once the key is rotated from the state illustrated in FIG. 1 to the state illustrated in FIG. 2, the key cannot be removed from the display lock 130. This is one way to attempt to remind the user that the display lock 130 is in the released state such that merchandise can be removed from the bottom bar 116.
With reference to FIG. 1, the rear mount 112 is illustrated mounting the plate hook 110 to the pegboard 106. Rear mount 112 includes a metal stamping 252 that is operably welded to the vertical portion of the display hook 110 extending between the top and bottom bars 114, 116. The rear mount 112 also includes a plastic protective cover 254 that engages with the metal stamping 252 to secure the peg hook 110 to the pegboard 106. The use of the protective cover 254 conceals the metal stamping 252 to prevent complete theft of the display hook 110 including the merchandise 102 attached thereto. The interaction between the metal stamping 252 and protective cover 254 is configured such that a tool is required to disengage the two components to allow the display hook 110 to be removed from the pegboard 106. Typically, the handle end of the key 210 is configured to disengage the two components.
With additional reference to FIGS. 11-15 the operation of the rear mount 112 will be described.
With primary reference to FIGS. 11 and 12, the metal stamping 252 includes a pair of bent feet 256 that extend through adjacent apertures 108 in the pegboard 106. The feet 256 include a back portion 258 and an extension portion 259 that extend generally perpendicular to one another. The back portion 256 will remain behind and generally parallel with the pegboard 106 when the metal stamping 252 is mounted to the pegboard. The extension portion 259 will extend axially through the aperture 108 in the pegboard 106 and connect the front body portion 262 of the stamping 252 to the back portion 258.
When mounting the stamping 252 to the pegboard 106, the user will insert the back portion 258 through the aperture 108 and then rotate the stamping approximately 90° such that the front portion rests against the front surface of the pegboard 106. During the rotation step, the extension portion 260 will then extend through the aperture 108.
The front body portion 262 includes a pair of wing sections 263 that connect to a central portion 264 that connects the two wing portions 263 to one another. The central portion 264 is configured to be spaced from the front surface of the pegboard 106 to define a cavity 265 between the front surface of the pegboard 106 and the central portion 264. The front body portion 262 includes a pair of upstanding wall portions 266 that extend outward from the wing sections 263 to connect the central portion 264 to the wing portions 263. The upstanding wall portions 266, in the illustrated embodiment, extend generally perpendicular to both the wing sections 263 and the central portion 264. These upstanding wall portions 266 space the central portion 264 from the front surface of the pegboard 106 to define cavity 265.
The upstanding wall portions 266 include attachment recesses in the form of cavities 268. These cavities 268 are used for attaching the protective cover 254 to the metal stamping 252 when the display hook 110 is attached to the pegboard 106. In other embodiments, the recesses need not extend entirely through the upstanding wall portions 266.
The protective cover 254 generally includes a pair of bent feet 270 that are configured much like the feet 256 of the metal stamping. The bent feet 270 include a back portion 271 and extension portion 272 that operate just like that of the bent feet 256 of the metal stamping 252. As such, the protective cover 254 is mounted to the pegboard 106 by inserting the back portion 271 through an aperture 108 in the pegboard 106 and then rotating 90° to locate the extension portion 272 within the aperture with the back portion 271 adjacent and generally parallel to the back surface of the pegboard 106.
The protective cover 254 includes a generally U-shaped body 274. The U-shaped body 274 generally includes a pair of interconnected leg portions 276 that form a channel 275 therebetween.
A pair of latch catches 278 extend laterally into the channel 275. The latch catches 278 are resilient and are configured to snap into the cavities 268 of the upstanding wall portion 266 of the metal stamping 252. These latch catches 278 will secure the protective cover 254 to the metal stamping 252 to prevent the protective cover 254 from being removed from the metal stamping 252 when the two components are connected to prevent removal of the display hook 110 from the pegboard 106. The latch catches 278 have canted outer faces that act as cams and allow for sliding the latch catches 278 across the upstanding wall portion 266 while rotating the protective cover 254 into the mounted state as illustrated in FIG. 1. The canted surfaces assist in flexing the latch catches 278 away from one another during the mounting process. The latch catches 278 include a flat catch surface that cooperates with a corresponding flat catch surface 281 defined by the cavity 268.
By having the U-shaped body 274 with channel 275, the protective cover 254 can be rotated past the top and bottom bars 114, 116 of the display hook 110 during assembly. The top and bottom bars 114, 116 extend through the channel 275 and are interposed between the leg portions 276 when assembled.
A key or tool must be inserted into cavity 265 such that it flexes the latch catches 278 laterally away from one another and out of engagement with the catch surfaces 281 of the metal stamping 252 to remove the protective 254 from the metal stamping.
The leg portions 276 (with reference to FIG. 14) include a plurality of abutment surfaces 284 that rest against the outer face of the wing sections 263 of the metal stamping. The abutment surfaces 284 are formed in ribbed portions 285 of the U-shaped body 274 and particularly the leg portions 276. The wing sections 263 are thus sandwiched between the rib portions 285 of the U-shaped body 274 and the front surface of the pegboard 106 when fully assembled. This arrangement is illustrated in FIG. 12. With reference to FIGS. 13 and 14, the U-shaped body 274 defines a outer skirt 286 that has an abutment face 287 that will rest against the outer surface of the pegboard 106 and hide wing sections 263 when assembled. Thus the abutments surfaces 284 of the ribs 285 are laterally recessed relative to the abutment face 287 of the outer skirt 286.
Now that a general description of the display lock system 100 has been described, the operation and assembly thereof will be described.
The display hook 110 will first be mounted to the pegboard 106 by inserting the bent feet 256 of metal stamping 252 into apertures 108 of the pegboard 106. At this time, the top and bottom bars 114, 116 will be extending substantially vertically so that the back portions 258 of the metal stamping 252 can be inserted axially into apertures 108. The display hook 110 will then be rotated approximately 90° such that the bottom bars 114, 116 extend outward from the front face of the pegboard 106 such as illustrated in FIG. 1.
The protective cover 254 can then be attached to the pegboard 106 and the metal stamping 252. The feet of the protective cover 254 will then be inserted into corresponding apertures 108 of the pegboard 106. The protective cover 254 will then be rotated 90° and such that the latch catches 278 will engage the cavity 268 of the metal stamping 252. At this point, the display hook 110 is generally attached to the retail support such as the pegboard 106. Again, similar mounting would apply if a slatwall were used.
The display lock 130 can then be attached to the display hook 110. To attach the display lock 130, the user will first locate the lock body 132 of display lock 130 over the top bar 114 with the top bar 114 extending through the mounting channel 134 of the lock body such that the lock body 132 will straddle and be saddled over the top bar 114. Typically the location of the lock body 132 will be in a generally coined or flattened section of the top bar 114. The user can, if necessary, then insert the lock pins 202 and the ring members 216 into the corresponding channels of the lock body 132.
The lock bar 142 will then be positioned adjacent to the distal ends of the lock body 132 with the distal ends 148, 149 of the lock bar 142 sandwiching the lock body 132 thereinbetween. The user can then insert the attachment pin 136 through the corresponding apertures in the lock bar 142 and the lock body 132 to secure the display lock 130 to top bar 142. As the attachment pin 136 is being inserted through the distal ends 148, 149 and the lock body 132, the attachment pin 136 will also extend through the aperture 138 in the coined region of the top bar 114. The threaded lock nut 164 can then be threaded on to the threaded end 162 of the attachment pin. A cap or cover can then be inserted into the lock nut 164.
While locating the lock bar 142 relative to the lock body 132, the lock bar 142 may be separated into its two separate components. This will allow distal end 149 to be located proximate the lock body 132 easily. The user can then attach the separate component 184 to the rest of the lock bar 142 and locate it proximate the opposite end of the lock body 132. This makes for ease of assembly particularly if the lock bar 142 and the lock body 132 are formed from non-flexible material such as rigid metal.
The user can use the key 210 to transition the lock bar 142 to the open state illustrated in FIG. 2 if necessary. The user can then load the bottom bar 116 with merchandise 102. After the bottom bar 116 is loaded with merchandise, the user can then transition the lock bar 142 to the closed state as illustrated in FIG. 1. This will secure the merchandise 102 on the display hook 110.
It is noted that the present display lock 130 has the key interface on a side of the display lock such that it does not need to be inserted into the display lock 130 from the bottom or the front of the display lock. This makes it much more useful and easier to insert the key into the display lock 130. This is particularly true if the display lock 130 is positioned between different pieces of merchandise or on a lower portion of the retail display.
