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.
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.
Embodiments of the present invention relate to new and improved display lock systems and particularly display locks for use with merchandise display systems. The new and improved display lock provides easier access to the display lock for engagement with a key. The new and improved display lock system also includes a protective cover and arrangement for securing a display hook to a display support such as a peg board or slat wall.
In one embodiment, a retail merchandise lock for securing merchandise on a merchandise display hook of a retail display is provided. The retail merchandise lock comprises a lock body, a lock bar and lock arrangement between the lock body and the lock bar. The lock body defines a mounting channel for receiving an bar or bar of the merchandise display hook therethrough. The lock bar is rotatably coupled to the lock body for rotation about a lock bar axis. The lock bar defines a lock bar aperture configured to receive a second bar of the merchandise display hook therethrough in a direction that is substantially perpendicular to the lock bar axis. The lock arrangement acts between the lock bar and the lock body. The lock arrangement has a locked state in which the lock bar is prevented from rotating about the lock bar axis relative to the lock body, and an unlocked state in which the lock bar is allowed to rotate about the lock bar axis relative to the lock body. In one embodiment, the lock bar does not affect the mounting of the display lock to the display hooks.
In one embodiment, an attachment pin extends through the mounting channel for securing the lock body to the bar. The attachment pin is spaced away from a bottom of the mounting channel which is generally trough shaped. The attachment pin and mounting channel are configured such that the attachment pin can pass through an aperture formed through the bar of the merchandise display hook.
In one embodiment, the lock arrangement includes a lock pin. The lock pin extends across a shear interface formed between the lock body and the lock bar. The lock pin engages both the lock body and the lock bar in the locked state to prevent rotation of the lock bar relative to the lock body in the locked state. The lock pin does not extend across the shear interface and not engaging the lock bar in the unlocked state to allow rotation of the lock bar relative to the lock body in the unlocked state. The lock pin is slidable between the locked and unlocked states along a pin axis and relative to the lock body.
In one embodiment, a spring member biases the lock pin toward the locked state.
In another embodiment, the lock pin is slidably carried in a lock pin channel formed in the lock body. The lock bar includes a first pin pocket. The lock pin extends into the first pin pocket in the locked state and is removed from the first pin pocket in the unlocked state. The lock pin engages the portion of the lock bar forming/bounding the first pin pocket in the locked state to prevent rotation of the lock bar relative to the lock body.
In one embodiment, the lock bar includes a key slot arranged to receive a key therein in a direction extending generally parallel to the pin axis of the lock pin. The key slot aligns with the lock pin providing access to the pin for axially engaging and biasing the pin to the unlocked state along the pin axis.
In one embodiment, the key slot is non-circular such that rotation of the key within the key slot will cause rotation of the lock bar.
In one embodiment, the lock bar is generally clevis shaped including a first leg portion and a second leg portion. The lock body is interposed between the first and second leg portions. In a more particular embodiment, an attachment pin extends through a first end of the first leg portion, through the lock body and into a second end of the second leg portion.

In one embodiment, the attachment pin is a bolt and the first end portion is a head of the bolt and the second end portion is a nut threaded onto an end of the bolt. The first end of the first leg is detachable from the rest of the lock bar to assist mounting to a bar of the display hook.
In one embodiment, a key is provided for transitioning the lock arrangement between the locked and unlocked states. The first end of the first leg portion includes a key receiving aperture configured to receive the key for engagement of the key with the lock arrangement. In a more particular embodiment, the key includes a central aperture. The central aperture receives the first end portion of the attachment pin when the key is inserted into the key receiving aperture.
In one embodiment, the lock bar includes a second pin pocket. The lock pin extends into the second pin pocket in a second locked state that is different than the other locked state. Preferably, the lock bar is in a second angular orientation relative to the lock body in the second locked state.
In a further implementation of the invention, a retail display system or display lock system is provided. The display lock system a merchandise display hook and a display lock. The display hook has first and second bars. The second bar is configured to carry merchandise. Typically, the second bar is below the first bar. The display lock includes a lock body, a lock bar and a lock arrangement. The lock body defines a mounting channel for receiving the first bar of the merchandise display hook therethrough. The lock bar rotatably coupled to the lock body for rotation about a lock bar axis that is generally perpendicular to the first and second bars of the merchandise display hook. The lock bar and lock body form a complete securing loop that surrounds the second bar. The lock arrangement acts between the lock bar and the lock body. The lock arrangement has a locked state in which the lock bar is fixed relative to the lock body in a closed state relative to the second bar where the lock bar inhibits removal of merchandise from the second bar. The lock arrangement has an unlocked state in which the lock bar is allowed to rotate about the lock bar axis relative to the lock body to an open state where the lock bar does not inhibit removal of merchandise from the second bar.
In one embodiment, the first bar includes a mounting aperture therethrough. The display lock includes an attachment pin. The attachment pin extends through the mounting channel and the mounting aperture to secure the lock body and lock bar to the first bar.
In one embodiment, the attachment pin is co-axial with the lock bar axis.
In one embodiment, the lock bar includes first and second leg portions that are spaced apart from one another along the lock bar axis. The first and second leg portions are coupled together by a bend or bent portion. The second bar of the display hook extends through a cavity formed between the first and second leg portions, the lock body, and the bend when the lock bar is in the closed state. The second bar does not pass through the cavity when the lock bar is in the open state.
In one embodiment, a support structures is provided to which the merchandise display hook is attached. The merchandise display hook further includes a metal stamping including at least one bent foot operably engaging the support structure to secure the merchandise display hook to the support structure. A protective cover extends over at least a portion of the metal stamping and includes a bent foot operably engaging the support structure to secure the protective cover to the support structure. The protective cover operably engages the metal stamping to secure the metal stamping to the support structure.
In one embodiment, the protective cover includes a cover body that is generally U-shaped defining a channel between a pair of legs. The protective cover is engaged with the metal stamping. The top and bottom bars are positioned between the pair of legs.
In one embodiment, the metal stamping includes first and second wings that are positioned proximate a front face of the support structure when mounted thereto. A first wall extends outward from and is connected to the first wing and a second wall extends outward from and is connected to the second wing. An intermediate portion extends between and connects the first and second walls. The intermediate portion is positioned between the pair of legs of the protective cover. A gap is formed between the intermediate portion and the front face of the support structure. The at least one bent foot of the metal stamping is connected to at least one of the first and second wings.
In another embodiment, the first and second walls include catch recesses formed in outer surfaces thereof. The protective cover includes an inward extending catch on each leg. The catches cooperate with the catch recesses to create the engagement between the protective cover and the metal stamping. This arrangement covers the metal stamping to prevent the metal stamping and the display hook from being removed from the retail support structure, e.g. peg board or slat wall.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
An exemplary embodiment of a display lock system 100 in accordance with the invention is illustrated in
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
With reference to
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
With additional reference to
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
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
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
With additional reference to
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
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
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
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

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
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
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
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
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.
