1. Technical Field
The present invention relates generally to merchandise display hooks that are attached to a display board or a wire display rack. More particularly, the present invention relates to display hooks that either prevent the rapid removal of items of merchandise from the display hook or prevent removal of items of merchandise when the display hook is locked. Specifically, the present invention relates to display hooks that can be locked to a display board or wire rack to prevent the removal of the display hook from the display rack while also preventing the removal of merchandise from the display hook or preventing rapid removal of the merchandise. In this application, the term “locked” is defined as a condition that requires a key to change the condition from locked to unlocked. A locked connection is thus more secure than a latched condition.
2. Background Information
Items of merchandise are commonly displayed for sale on long protruding rods supported from peg board or slat board. These protruding rods are commonly referred to in the art as peg board hooks or slat board hooks. Similar rods may also protrude from a wire display rack for the same purpose. Usually, the items of merchandise are of a smaller range, such as batteries or small tools or other components. Such merchandise is an easy target for shoplifters because they can rapidly remove all the items from a display hook and remove the merchandise from the store without being detected. Alternately, the entire display hook with the merchandise can be removed from peg boards and the like if they are not locked thereon. Therefore, it is desired in the art to provide security hooks that prevent both the removal of the display hooks from the peg boards or wire racks and the rapid removal of items of merchandise from the display hooks.
In one embodiment, the invention provides a lockable display hook wherein the base of the display hook locks directly to the rod of the display hook. The base is slides along the rod between locked and unlocked positions wherein the display hook may be removed from the support wall when the base is in the unlocked position. A spring-biased latch extends between the rod and base to lock the two elements together in the locked position.
Another aspect of the invention is a lockable end assembly that prevents merchandise from being removed from the display rod.
Another aspect of the invention is that the key used to unlock the base or the end assembly may be held in place on the base or end assembly in a hands-free condition allowing the user to load the device with both hands.
In another embodiment, the invention provides a base that is adapted to be used with a wire frame support structure. The base allows different desirable mounting configurations.
In another embodiment, the invention provides a lockable display hook having a rod that holds merchandise wherein the rod may pivot between locked and loading positions. The loading position allows merchandise to be loaded onto the rod quickly while the locked position limited the rapid removal of the merchandise.
In a further embodiment, the invention provides a base that pivots between the locked and unlocked positions.
Similar numbers refer to similar parts throughout the specification.
The merchandise display hook of the present invention is indicated generally by the numeral 100 and is shown in
Lockable base assembly 106 selectively secures display hook 100 to display board 102 in a manner that prevents display hook 100 from being removed from display board 102 without the use of a specific key 114 (FIG. 4). As used in this application, the term “locking” is different than a simple “latched” connection. A “latched” connection may be unlatched without the use of a special key while a “locked” connection requires a special key. Display board 102 includes a plurality of holes 103. Hook 112 includes a pair of upwardly extending ends 111. Key 114 includes a first magnet 113, a second magnet 115 and a protuberance 117. Base assembly 106 includes a foot 116 and a leg 118 extending outwardly therefrom. Leg 118 includes an upper wall 119. Base assembly 106 further includes chair member 120 which is connected to foot 116 by a screw 122, although this connection may be by any of a variety of connectors known in the art.
Leg 118 defines a hole 124 and an interior chamber 126 disposed above and communicating with hole 124. Interior chamber 126 is bounded on one end by a portion of chair member 120. Base assembly 106 further defines a recess 128 in leg 118 where leg 118 and foot 116 converge. Recess 128 receives protuberance 117 of key 114 as further described below. Base assembly 106 further defines a passage 130 adjacent a lower end 132 of foot 116.
A first embodiment of the rod assembly is shown generally at 108 and includes an upper rod 134 and a lower rod 136 joined by a connecting rod 138 adjacent an inner end 140 of rod assembly 108. Upper rod 134 defines an upwardly facing notch 142 adjacent inner end 140 of rod assembly 108. Notch 142 is bounded on one end by a ledge 143. Upper rod 134 is cylindrical and has an outer end 144 adjacent which upper rod 134 defines a pair of upwardly facing notches 146 and 148 having respective outer ledges 150 and 152. Lower rod 136 has an outer end 154 having a circular cross-section.
A second embodiment of the rod assembly is shown generally at 108A in
A locking mechanism 159 disposed within base assembly 106 includes a locking finger assembly 160 which includes a spring element 162 having a base 164 and a finger 166 cantilevered from one end of base 164 and angling outwardly therefrom, being spring-biased in this outwardly angling position. Finger assembly 160 may optionally include a strengthening element 168 that includes a U-shaped portion 170 and a pair of wings 172 extending outwardly from a respective pair of arms 171 of the U-shaped portion 170.
The relationship between base assembly 106, rod assembly 108 and locking finger assembly 160 is as follows. Upper rod 134 slidably and lockably extends through hole 124 of base assembly 106 and lower rod 136 likewise slidably passes through passage 130 of base assembly 106. Finger assembly 160 is disposed within interior chamber 126 of leg 118 with spring element 162 lying adjacent upper wall 119 of leg 118 and strengthening element 168 being disposed below spring element 162. In a locked position (FIG. 11), wings 172 of strengthening element 168 are disposed within notch 142 of upper rod 134 with finger 166 of spring element 162 extending downwardly due to its spring bias toward notch 142. In an unlocked position (
A first embodiment of the end assembly is indicated generally at 110 and is depicted in
A embodiment of the end assembly is indicated generally at 110A and is shown in
In operation, merchandise display hook 100 is configured to attach to display board 102, as shown in
The locked position of base assembly 106 is shown in
To unlock locking mechanism 159 of base assembly 106, key 114 having a magnet 113 encased therein is placed adjacent leg 118 above spring element 162 and strengthening element 168, thereby attracting finger 166 of spring element 162 and strengthening element 168 upwardly out of notch 142, as shown in FIG. 4. With strengthening element 168 removed from notch 142, base assembly 106 is in the unlocked position and free to slide along rod assembly 108. Once base assembly 106 has moved along rod assembly 108 to the extent that wings 172 of strengthening element 168 are no longer above notch 142, the magnetic key 114 may be removed and base assembly 106 is able to slide along rod assembly 108 without the use of key 114. It is noted that only the first magnet 113 of key 114 is needed to unlock locking mechanism 159, but both first magnet 113 and second magnet 115 may be used to unlock locking mechanism 174 of end assembly 110, 110A, as described further below.
To facilitate pulling base assembly 106 outwardly along rod assembly 108, protuberance 117 of key 114 engages recess 128 of base assembly 106. In addition, the magnetic aspect of key 114 allows it to hold itself to base assembly 106 above spring elements 162 and strengthening element 168 while base assembly 106 is moved along rod assembly 108. Thus, a user may manipulate base assembly 106 without needing to hold on to key 114 or put it down somewhere during this process.
In accordance with the present invention, each end assembly 110, 110A slides along rod assembly 108 and 108A, respectively, and has a locking mechanism 174 to selectively lock end assembly 110, 110A to upper rod 134. Locking mechanism 174 utilizes a spring element similar to spring element 162 in base assembly 106. However, the preferred embodiment of end assembly 110, 110A includes a pair of fingers, namely inner finger 191 and outer finger 198 of spring element 196, to engage respective notches 146 and 148 of upper rod 134. As no strengthening element is used as with locking mechanism 159 in base assembly 106, the use of a pair of fingers adds strength to locking mechanism 174. Magnetic key 197 is used to unlock locking mechanism 174 as described in relation to base assembly 106 except, as noted, there is no strengthening element 168 involved. Locking mechanism 174 of end assembly 110, 110A and locking mechanism 159 of base assembly 106 may be opened by a common key. Like key 114 used with locking mechanism 159 of base assembly 106, the magnetic aspect of key 197 allows key 197 to hold itself to end assembly 110 or 110A above spring elements 162 while end assembly 110 or 110A is moved along rod assembly 108 or 108A, respectively. This allows a user to manipulate end assembly 110 or 110A without having to hold on to key 197 or put key 197 down somewhere while loading items 104 of merchandise onto lower rod 136. In a locked position shown in
As noted above, end assembly 110 (
Regarding end assembly 110A (FIGS. 19-22), when locking mechanism 174 is in the unlocked position and end assembly 110A is slid outwardly along rod assembly 108, projection 180 engages ledge 150 as shown in
It will appreciated that many variations exist of the merchandise display hook without departing from the spirit of the invention. For example, the locking mechanism found in base assembly 106 may have a variety of configurations and need not be opened by a magnetic key. Most importantly, base assembly 106 is slidable along rod assembly 108 and is also lockable to rod assembly 108 in such a manner as to lock the merchandise display hook to a display board. Further, the rod assembly could have only one rod to which the end assembly would be lockable and removable so that the single rod could also function as the support for the items of merchandise. Like the base assembly, the end assembly may also have a variety of locking mechanisms to lock the end assembly to the rod assembly. These and other variations may be made without departing from the spirit of the invention.
Thus, merchandise display hook 100 provides a display hook which both locks to a display board via a lockable base assembly 106 and also includes an end assembly 110 which locks to rod assembly 108 to prevent removal of items 104 of merchandise when in a locked position. Merchandise display hook 100 thus prevents a potential shoplifter from removing items 104 of merchandise from display hook 100 or removing display hook 100 from a display board 102.
A second embodiment of the present invention is indicated generally at numeral 200 and is shown in
Lockable base assembly 206 is similar to base assembly 106 with the exceptions described below and includes a locking mechanism which is the same as that of base assembly 106. Base assembly 206 selectively secures display hook 200 to wire rack display board 202 in a manner that prevents display hook 200 from being removed from display board 202 without use of a specific key like key 114 used with merchandise display hook 100. Base assembly 206 includes a foot 212 and a leg 214 extending outwardly therefrom. As shown in
Hook 210 includes a pair of upwardly extending spaced fingers 220 and a downwardly extending tongue 222, as seen in FIG. 24. Hook 210 further includes a pair of spaced claws 224 having respective sides 225 and extending outwardly and then downwardly from respective fingers 220. Hook 210 is connected to rod assembly 208 by a weld 226 or by other means known in the art.
Rod assembly 208 includes an upper rod 228, a lower rod 230 and a connecting rod 232 formed integrally with and connecting upper rod 228 and lower rod 230. Rod assembly 208 has an inner end 234 and an outer end 236. Adjacent inner end 234, upper rod 228 defines a sloping notch 238 bounded by a ledge 240. A display face 242 is connected to upper rod 228 at the outer end 236 of rod assembly 208. Adjacent outer end 236, lower rod 230 includes an upwardly extending portion 244. Lower rod 230 terminates in an upwardly extending tip 246 which also angles inwardly toward inner end 243 of rod assembly 208.
In operation, merchandise display hook 200 functions as follows. In accordance with the present invention, base assembly 206 is slidable along rod assembly 208 in the unlocked position and lockably engages with ledge 240 of slot 238 in the locked position via locking mechanism 159 as used with display hook 100. To install display hook 200 on wire rack display board 202, base assembly 206 is unlocked and slid outwardly along rod assembly 208 away from hook 210, as shown in FIG. 23. In this position, sides 225 of claws 224 of hook 210 are open so that claws 224 may hook over a horizontal wire 203 of wire rack display board 202. Once installed, tongue 222 of hook 210 abuts a lower horizontal wire 203, thus preventing display hook 200 from pivoting downwardly about the upper wire 203 over which claws 224 are hooked. This keeps rod assembly 208 in a substantially horizontal position, as seen in FIG. 22. Once display hook 200 is installed on wire rack 202, base assembly 206 is slid along rod assembly 208 toward hook 210 into the locked position, as shown in FIG. 24. In the locked position, tabs 218 of base assembly 206 are situated just outside claws 224 closely adjacent respective sides 225, as shown in
In accordance with the present invention, the spaced configuration of fingers 220 and claws 224 of hook 210 allows a plurality of display hooks 200 to overlap one over the other as shown in
As shown in
In accordance with the present invention, the spaced nature of claws 224 also allows display hook 200 to extend from opposite sides of wire rack 202 in an overlapping of fashion with another display hook 200, as shown in FIG. 27. In this configuration, one claw of each display hook 200 is disposed between the spaced pair of claws 224 of another display hook 200 while the respective rod assemblies 208 of the overlapped display hooks 200 extend outwardly in opposite directions from opposite sides of wire rack 202. This usage is allowed in part by the fact that, except for claws 224 and tabs 218, no portion of display hook 200 extends beyond the side of wire rack 202 on which a given display hook 200 is mounted. Thus, each display hook 200 connected to wire rack 202 in a back-to-back fashion does not interfere with the other. Again, this allows for a compact usage of display hook 200.
It will be appreciated that a variety of configurations can achieve similar results without departing from the spirit of the present invention. For instance, a tongue like tongue 222 may extend upwardly and have a claw formed thereon from which display hook 200 would hang while fingers like fingers 220 may extend downwardly to engage wire rack 202 to prevent the downward pivoting movement. In short, the tongue and fingers may switch positions. By way of further example, instead of having a tongue 222 extending downwardly, hook 210 may have members extending outwardly to engage vertical wires 205 of wire rack 202. In an alternative configuration, claws like claws 224 may be adapted to lockably engage vertical wires 205 while resting on horizontal wires 203. Nonetheless, in the preferred embodiments, the configuration of claws 224 and tongue 222 maintains a compact unit while allowing the functions as described.
A third embodiment of the present invention is indicated generally at 300 and is shown in
Lockable base assembly 306 selectively secures display hook 300 to display board 302 in a manner that prevents display hook 300 from being removed from display board 302 without the use of a specific key, like key 114 used in the first embodiment. Base assembly 306 includes a foot 316 and a leg 318 extending outwardly therefrom. Leg 318 is similar to leg 118 except that it extends further downwardly below lower rod 314. Leg 318 includes an upper wall 319 and a lower wall 317. Base assembly 316 further includes a chair member 320 which is connected to foot 316 by a screw 322.
Leg 318 defines an upper hole 324 and an interior chamber 326 disposed above and communicating with hole 324. Interior chamber 326 is bounded on the one end by a portion of chair member 320. Base assembly further defines a lower hole 330 adjacent lower wall 317 of leg 318.
Rod assembly 308 includes an upper rod 334 and in accordance with the present invention, a rotatable lower rod 336 joined by a housing 338 adjacent an inner end 340 of rod assembly 308. The outer portions of rod assembly 308 are essentially the same as rod assembly 208. Thus, upper rod 334 has a display face 342 connected to upper rod 334 at an outer end 343 of rod assembly 308. When in the anti-sweeping position, the outer portion of rotatable lower rod 336 is essentially the same as rod 230. Thus, lower rod 336 includes a portion 344 that extends upwardly toward upper rod 334 and also terminates in a tip 346 extending upwardly toward upper rod 334 and inwardly toward inner end 340 (FIG. 39).
Housing 338 (
In accordance with the exemplary embodiment of the present invention, lower rod lock 314 includes housing 338 and the following elements. A stationary stop 362 is disposed within housing 338 adjacent high wall 358 and base 348. Moveable stop 364 includes an arcuate arm 366 which extends upwardly above low sidewall 360 and inwardly toward high sidewall 358 when base assembly 306 is in the locked position. Adjacent inner end 340 of rod assembly 308, a projection 368 in the form of a short rod extends radially outward from rotatable lower rod 336 and is connected thereto by welds 371. The short rod used as projection 368 extends parallel to lower rod 336.
Locking mechanism 310 of base assembly 306 is very similar to that of the first embodiment and may include the same strengthening elements 168, which functions in the same manner as in the first embodiment. Spring element 370 is similar to spring element 152 in that it includes a base 372 and a finger 374. However, spring element 370 also includes a tab 376 extending at right angles to base 372. Tab 376 defines a hole 378 through which screw 322 extends to connect chair member 320 and spring element 370 to foot 316 of base assembly 306. Aside from tab 376 and its connection as described, spring element 370 functions in the same manner as spring element 162.
The relationship between base assembly 306, rod assembly 308 and housing 338 is as follows. Upper rod 308 slidably and lockably extends through hole 324 of base assembly 306 and rotatable lower rod 336 likewise slidably passes through hole 330 of base assembly 306. Upper rod 334 is connected to inner wall 350 of housing 338. Hook 312 is connected to upper rod 334 and extends through holes 353 of inner wall 350 of housing 338.
In operation, merchandise display hook 300 is configured to attach to display board 302, as shown in
As in the first embodiment, to allow display hook 300 to angle upwardly to insert ends 311 through holes 303, base assembly 306 must be moved outwardly from hook 312. Display hook 300 permits this outward movement because base assembly 306 in an unlocked position may slide outwardly along rod assembly 308, as shown in FIG. 28. Once hook 312 is inserted through holes 303 and display board 302, as shown in
In accordance with the present invention, when locking mechanism 310 of base assembly 306 is in the unlocked position and base assembly 306 is slid a short distance outwardly from hook 312, lower rod 336 may rotate between a loading position and an anti-sweeping position. The anti-sweeping position is shown in
In conjunction with horizontal slot 307 of package 305, the substantially horizontal position of portion 344 and tip 346 in the loading position allows items 304 of merchandise to be quickly loaded onto lower rod 336. However, in the anti-sweeping position, portion 344 and tip 346 are in the substantially vertical plane which prevents items 304 from being removed or loaded easily from lower rod 336. Items 304 of merchandise can only be removed quickly over the end of lower rod 336 when slot 307 is aligned with the plane along which portion 344 and tip 346 lie. Upper rod 334 interferes with the rotation of item 304 about lower rod 336, as the upper portion of package 305 would hit upper rod 334 in an attempt to thus rotate package 305. Thus, in the anti-sweeping position, slot 307 cannot be aligned vertically to allow rapid removal of items 304 of merchandise.
In accordance with the present invention, rod lock 314 functions as follows. Lower rod 336 is rotatable within holes 352 and 356 of housing 338 as well as hole 330 of base assembly 306 when locking mechanism 310 of base assembly 306 is in the unlocked position and moved a short distance outwardly from hook 312 to disengage rod lock 314, as described below. Projection 368 prevents lower rod 336 from being removed outwardly from housing 338 due to an interference between projection 368 and outer wall 338 when such removal is attempted. Inward movement of lower rod 336 is likewise prevented by a similar interference between projection 368 and inner wall 350 of housing 338. When locking mechanism 310 of base assembly 306 is in an unlocked position, and rod lock 314 is disengaged, the rotational movement of lower rod 336 is limited by an interference between projection 368 and stationary stop 362 in one direction and between projection 368 and low sidewall 360 of housing 338 in the other direction. The interferences with stop 362 and low sidewall 360 correspond respectively to the anti-sweeping position and the loading position. In the unlocked position of base assembly 306 and the disengaged position at rod lock 314, the rotational movement of lower rod 336 is limited to approximately 90 degrees of rotation. In the locked and engaged positions, the rotational movement of lower rod 336 is still limited by stationary stop 362 in one direction but limited in the other direction by moveable stop 364 of base assembly 306. More specifically, when base assembly 306 is slid inwardly toward inner end 340 of rod assembly 308, stationary stop 362 and moveable stop 364 are positioned to prevent the rotation of lower rod 336 as projection 368 abuts one of stops 362 and 364 when rotation is attempted. Lower rod 336 must be in the anti-sweeping position in order for base assembly 306 to slide into the locked position. This is due to the fact that in the loading position of rod 336, projection 368 will prevent base assembly 306 from sliding inwardly as moveable stop 364 engages with projection 368. When base assembly 306 is locked, lower rod 336 remains in the anti-sweeping position.
Display hook 300 thus provides a rod assembly 308 which attaches to a display board 302 and may be locked into a display position by base assembly 306 which slides along rod assembly 308. Further, in the unlocked position of base assembly 306 and disengaged position of rod lock 314, lower rod 336 is rotatable between a loading position and an anti-sweeping position wherein items 304 of merchandise may be quickly loaded or removed in the loading position but may not be rapidly removed in the anti-sweeping position.
A fourth embodiment of the present invention is indicated generally at numeral 400 and is shown in
Lockable base assembly 406 selectively secures display hook 400 to display board 102 in a manner that prevents display hook 400 from being removed from display board 102 without the use of a specific key 414 (FIG. 53). Display board 102 includes a plurality of holes 103, as shown in
Base assembly 406 includes a foot 416 and a leg 418 extending outwardly therefrom. Base assembly 406 includes an upper end 420, a lower end 422, an inner end 424, and an outer end 426. As seen in
A locking mechanism 444 is disposed in interior chamber 432 adjacent upper wall 419. Locking mechanism 444 includes a spring element 446 having a base 448 and a finger 450 angling outwardly from base 448. Spring element 446 is similar to spring element 162 of the first embodiment.
A bracket 452 is fixedly connected to upper rod 434 by a weld 454 or any suitable means known in the art. Bracket 452 extends radially outwardly from upper rod 434. Bracket 452 is generally circular, being modified with inwardly extending notches formed therein. The notches include a locking notch 456, an arcuate channel 458 and a by-pass 460. Bracket 452 includes a ledge 462 bounding one end of locking notch 456, a ledge 464 bounding one end of by-pass 460 and a pair of end ledges 466 bounding respective ends of arcuate channel 458. Bracket 452 is disposed in interior chamber 432.
In the locked position of base assembly 406, finger 450 of spring element 446 extends into locking notch 456 and engages ledge 462 (FIGS. 51-52). In the unlocked position of locking mechanism 444, finger 450 is disposed outside of locking notch 456 (FIG. 53). In the unlocked position of base assembly 406, finger 450 lies within by-pass 460 and arcuate projection 442 is aligned with arcuate channel 458 (FIG. 54).
In operation, in accordance with one of the main features of the invention, base assembly 406 rotates about upper rod 434 between the locked position and unlocked position of base assembly 406. In the locked position, base assembly 406 prevents display hook 400 from being removed from display board 102. In the unlocked position of base assembly 406, base assembly 406 may be slid outwardly along rod assembly 408, thus allowing display hook 400 to be removed from display board 102, as described in the first embodiment of the invention.
More specifically, as noted above, finger 450 of spring element 446 is disposed within locking notch 456 and engages ledge 462 to prevent the rotation of base assembly 406 about upper rod 434 in one direction when locking mechanism 444 is in the locked position.
In the locked position of base assembly 406, lower stop 429 engages rod assembly 408 to prevent rotation of base assembly 406 in the opposite direction (FIG. 55). To unlock locking mechanism 444, magnetic key 414 is placed above spring element 446 to draw finger 450 out of notch 456 (FIG. 53). In the locked position (
It will be appreciated that a variety of alterations may be made to display hook 406 without departing from the spirit of the invention. The key aspect of base assembly 406 is the incorporation of a locking mechanism which requires base assembly 406 to be rotated before being slid outwardly along rod assembly 408. Various configurations of locking mechanisms as well as the means to prevent outward movement of a base assembly along the rod assembly may be utilized. Another option incorporating a rotational movement is to have a portion of the base assembly rotate with respect to another portion of the base assembly in order to unlock the base assembly and allow it to move outwardly along the rod assembly.
Thus, merchandise display hook 400 provides a display hook which both locks to display board 102 via a lockable base assembly 406 and includes an end assembly 110 which locks to rod assembly 408 to prevent removal of items 104 of merchandise when in a locked position. Display hook 400 thus prevents a potential shoplifter from removing items 104 of merchandise from display hook 400 or removing display hook 400 from a display board 102.
