9 Claims, 14 Drawing Figures PEGBOARD DISPLAY RACK This invention relates to display racks for merchandise cards and more particularly to an improved pegboard display rack which provides for securely holding merchandise cards thereon until released by a sales clerk.

It is well known to display carded merchandise in retail stores by placing the merchandise on cards that are hung on hangers extending outwardly from a pegboard. Displaying merchandise in this manner is very desirable since it enables the customer to view the merchandise and select the items which he is interested in purchasing without taking up the time of the sales clerk. However, when displayed in this fashion, pilfering of the merchandise cards becomes a problem. Therefore, because of this pilferage problem, much of the shoplift prone type of merchandise; such as, steel tape rules, cassette tapes, small tools, and radio parts, for example, are usually kept in locked service cabinets. Thus, when a customer desires to purchase items such as these a sales clerk must open the cabinet and be present while the customer examines and selects the items he desires to purchase.

Accordingly, one of the objects of the present invention is to provide a pegboard display rack which includes locked merchandise card holding devices useful for displaying the types of merchandise which generally have a high risk from shoplifters.

Another object of the present invention is to provide a display rack which fully displays carded merchandise items while keeping the items secured to the display rack until released by a sales clerk.

Another object of the present invention is to provide for securely displaying items of merchandise in a display rack in such a manner as to enable a customer to leisurely examine and select the item or items he desires to purchase without taking up the time of the sales clerk.

Still another object of the present invention is to provide an improved display rack structure which operates to securely hold merchandise cards on each of a plurality of hangers attached to a pegboard until the display rack is unlocked by a sales clerk.

Other objects and features of the present invention will become apparent during the course of the following part of the specification wherein the details of construction and mode of operation of a preferred embodiment are described with reference to the accompanying drawings, in which:

FIG. 14 is a sectional view of the tubular hanger showing the rod advanced forwardly therein so as to expose the knob on the forward end thereof.

Referring to FIGS. 1 and 2, the display rack 10 of the present invention includes a vertically disposed rectangular sheet of metal pegboard 11 having thereon an array of diamondshaped openings 13. The edges of the metal pegboard are bent back to form the top 14, bot tom 15, and sides 16 of the display rack 10. Disposed in the enclosure formed on the back of the pegboard is a movable plate 20. Each corner of the plate 20 is provided with a boss 21, to which one end of a link 23 is pivotally attached by a bolt 24. The other end of the link 23 is pivotally attached by a bolt 25 to the side 16 of the display rack 10. The links 23 enable the plate 20 to be maintained parallel to the pegboard while being moved inwardly and outwardly relative thereto. The movable plate 20 is normally forced outwardly by one or more compressed springs 28 each of which is mounted at one end by a pin 28a attached to the plate 20. The springs 28 thus force the pegboard 11 and plate 20 apart until the side of the link 23 on the upper corner of the plate 20 contacts a pin stop 29 secured to the side 16 of the rack 10.

As shown in FIG. I, supported at arbitrarily spaced locations on the pegboard 11 are a plurality of card holding devices 30. Additional card holding devices can be supported on other portions of the pegboard 11,

e not. shown. Each card holding device 30 includes a bracket 31 by which it is attached to the pegboard 11, and a horizontally extending tubular hanger 32. The inner end of the tubular hanger 32 is welded or otherwise securely connected in an opening 31a on the center of the bracket 31. A plurality of merchandise cards 35 are supported on the tubular hanger by an opening 36 provided on each of the cards for that purpose. A dog or retaining post 40 normally projects downwardly near the forward end of each of the tubular hangers 32 for preventing the cards 35 from being withdrawn off the forward end of the tubular hanger 32. It should be noted that the forward end of the tubular hanger 32 is open.

Referring to FIG. 8, positioned for sliding movement within the tubular hanger 32 of each of the card holding devices 30 is an elongated actuating rod 42. The retaining post 40 is pivotally mounted near the forward end of the actuating rod 42 and extends through a slot 65 (FIG. 9) on the bottom wall near the forward end of the tubular hanger 32. A bolt 33 is threadably attached by its end in a hole 44 provided on the rear end of the rod 42. A spring 45 encircles the body of the bolt 43. The inner end of spring 45 bears on a washer 46 which rests against the back of the bracket 31, and the outer end of spring 45 bears on the head 43a of bolt 43 so as to force the actuating rod outwardly from the back of the tubular hanger 32 until the head 43a of the bolt contacts the movable plate 20.

As will be described more fully hereinafter, when the actuating rod 42 of a card holding device 30 is forced backwardly by the spring 45, the retaining post 40 is held in its vertically projecting position which prevents removal of the merchandise cards 35 off the end of tubular hanger 32. On the other hand, when the actuating rod is advanced into the tubular hanger 32 be depressing the plate 20, the retaining post 40 is pivoted backwardly so as to be substantially enclosed within the tubular hanger 32 and thus enables the cards 35 to be slid past the post 40 and off the end of the hanger 32.

Located on the front of the pegboard 1 1 is an operating handle 48. As shown in FIG. 5, a support 34 is welded on the inner surface of the rack near the side 16 thereof. The support 34 is provided with a circular opening 38 which is aligned with a similar circular opening 39. on the side 16 of the rack 10. A bushing 50 passes through the

openings

38 and 39 and is held in position by a bolt 71 and nut 72. A lever 37 having an outer arm 49 and an inner arm 52 is rotatable mounted by a bore located at its fulcrum point on the bushing 50. The operating handle 48 is attached to the outer arm 49 and a roller 54 is secured by a bolt 54a ,to the end of the inner arm 52. I

Also located on the front of the pegboard 11 is a travel stop 64 which comprises a threaded body with an enlarged inner end 66. A fitting 68 is held on the pegboard by a nut 73. The body of the travel stop 64 threadable engages an axial opening in the fitting 68. The outer end of stop 64 is adapted to receive an Allenhead wrench which is used to adjustably position the inner end 66 of the stop 64 and thereby limit the inward movement of the plate 20.

The plate 20 is moved inward by applying a force directly thereon, or, if the display rack 10 is mounted against a wall, the operating handle 48 on the front of the display rack can be lifted to rotate lever 37 about the bushing 50. This causes the roller 54 on the end of the inner arm '52 to force the plate 20 toward the pegboard 11 and the actuating rods 42 of each of the card holding devices 30 inwardly so as to cause the retaining post 40 on the forward ends of the hangers 32 to be pivoted into the slots 65 thereof.

A lock 27 for the display rack 10 is provided on the pegboard 11. The body 58 of the lock 27 extends through an enlarged opening 59in the pegboard l1 and is provided with a cap 60 that bears against the front surface of the pegboard 11. A nut 61 engages a threaded portion of the body 58 and contacts the back surface of the pegboard 11. The lock 27 has a central rotatable shaft 62 with a lock arm 63 attached to the end thereof. When the display rack 10 is locked, the lock arm 63 is swung to extend in front of and adjacent the front surface of the plate 20, thus preventing it from being pushed inwardly. Upon inserting a key (not shown) in the keyhole of the lock 27, the lock arm 63 can be rotated to a position indicated by dash lines 63' wherein the lock arm resides in a clearance opening 64a on the plate 20. When the lock arm 63 is in this latter position, the plate 20 can be pivoted forwardly by its links 23 while maintaining its position parallel with the pegboard, as shown in FIG. 7, so as to simultaneously advance all the actuating rods 42 into their respective tubular hangers 32. When the rods are so advanced, the retaining posts 42 are pivoted inwardly into the tubular hangers 32.

It is thus seen that the display rack 10 of the present invention provides for securing a plurality of merchandise cards 35 on each of a plurality of tubular hangers 30 by controlling the positioning of a retaining post 40 pivotally mounted near the forward end of each of the tubular hangers 32. The plate 20 is normally prevented from being advanced inwardly by the lock 27, and, accordingly, the posts 40 are normally locked in their outwardly projecting position so as to prevent the cards 35 from being removed off the ends of the hangers 32. By unlocking the lock 27 of the rack 10, the sales clerk can then push in the plate 20 which causes the advancing of all the actuating rods 42 into the tubular hangers 32 and the pivoting of posts 40 on the forward ends thereof inwardly into the hangers 32, thus permitting the cards to be removed from the ends thereof.

Upon the sales clerk releasing the plate 20, the actuating rods are again moved to their withdrawn position by the springs 45, and the retaining posts 40 are again swung to their outwardly projecting position on the hangers 32 in which they prevent removal of the cards 35. Then when the lock 27 is again rotated by a key so as to again position the locking arm 63 in front of the movable plate 20, the display rack 10 is again placed in a locked position.

The structure for holding the merchandise cards on the holding device 30 will now be further described by referring to FIGS. 8 to 14 of the drawings. Thus, the actuating rod 42 has near its forward end an elongated vertical. slot 51, and a shorter horizontal slot 53 which traverses the walls of the vertical slot 51. The front end of slot 51 is provided with an internal shoulder 55. The inner end of the post 40, which is formed with a side lug 41, is positioned within the vertical slot 51 and pivotally held thereon by a pin 56 which extends through the horizontal slot 53 and the hole 57 on the inner portion of the post 40. The outer portion of the post 40 extends through the slot 65 on the lower wall of the hanger 32. It should be understood that the ends of the pin 56 are freely movable along the shorter horizontal slot 53. Thus, as shown in FIGS. 9 and 10, when the rod is pulled out of the tubular hanger 42 by the spring 45 on the bolt 43 located on the rear portion thereof, the pin 56 is located on the forward end of the horizontal slot 53, and the post 40 is held against the back end of the slot 65 in the tubular hanger 32 with its side lug 41 engaging intemal shoulder on the front end of the vertical slot 51 on the rod 42.

It is thus seen that when the actuating rod is held in its withdrawn position by the spring 45 on the bolt 43, the outer portion of the retaining post 40 is anchored up against the rear end of the slot in the tubular hanger 32 and the internal shoulder 55 on the rod 42 engages the lug 41 on the inner portion of the retaining post 40. It should now be clear that the contact of the lug 41 with the internal shoulder 55 on the rod prevents the outwardly projecting post 40 from being pushed backward, and the contact of the flat inner end of lug 41 of the post with the inner wall of the tubular hanger 32 opposite the slot 65 prevents the outwardly projecting post from being pushed forward. Thus, the retaining post 40 is effectively secured in its outwardly projecting vertical position.

However, when a pressure is exerted on the plate 20, the rod 42 and the post 40 are initially moved together forwardly into the hanger 32 until the post 40 contacts the front end of the slot 65 on the forward end of the hanger 32, as shown in FIG. 12. As the rod 42 continues to move forwardly, the lug 41 on the post 40 becomes disengaged from the internal shoulder 55 on the front end of the vertical slot 51 in the rod 42 as the pin 56 slides towards the rear of the short horizontal slot 53. Continued forward movement of the rod 42 then causes the post 40 to be pivoted inwardly such that when the plate 20 moves to the position indicated by 20 in FIG. 4 wherein it contacts the inner end 66. of the travel stop 64 on the pegboard 11, the post 40 is substantially enclosed within the vertical slot 51 on the rod 42, as shown in FIG. 13. Thus, the merchandise card 35 can be removed from the hanger 32. It should be particularly noted that when the rod 42 is in this position, the knob 47 formed on the forward end thereof is still enclosed within the hanger 32.

Next to be described is the manner in which the card holding devices 30 are attached to the pegboard 11, and having once been attached, are detached only if the travel stop 64 has been properly adjusted and the display rack unlocked. Thus, assuming it is desired to mount a card holding device 30 at a particular position on the pegboard 11, the back end of the rod 32 is depressed into the hanger 32 until the knob 47, formed on the forward end of the rod 32, is exposed so that it can be gripped and held by the fingers or by a suitable tool so as to keep the rod 42 in its forward position. Then by tilting the end of the tubular hanger 32 upwardly, as shown in FIG. 6, the ears 33 on the upper corners of the bracket 31 can be inserted on a pair of spaced diamond-shaped holes 13 of the pegboard 11. As the tubular hanger 32 is then swung down to a horizontal position, the bolt 33 on the rear of the rod 42 is passed through a lower diamondshaped hole 13 in the pegboard 1 1. When the knob 47 on the front end of the rod 42 is now released, the rod is withdrawn out of the hanger 32 by the springs 45 until the head 43a of the bolt 43 contacts the plate 20. The lower end of the bracket 31 is then held up against the pegboard 11 by passing a plastic fastener 69 through the opening 67 in the bracket 31 and an aligned diamond-shaped hole 13 on the pegboard 11. The body of fastener 69 is segmented and provided with a centrally threaded opening adapted to receive an Allen-head screw 70. Advancing the screw 70 causes the plastic body segments of the fastener 60 to be cammed outwardly so as to secure the lower end of the bracket 31 on the pegboard 11.

It should be noted that once the knob 47 on the forward end of the rod 42 is released after the ears 33 on the bracket 31 are positioned in the holes 13 on the pegboard 11 and the bolt 43 is inserted in a lower hole 13 on the pegboard, the holding device 30 cannot be removed from the pegboard 11. This is because of the force on the end of the rod 42 by the spring 45 which prevents the bolt 43 from being withdrawn out of the hole 13 on the pegboard 11, even when the hanger 32 is tilted upwardly as required to release the ears 33 on the upper corners of the bracket 31 from the holes 13 on the pegboard 11.

After the card holding devices 30 are attached to the pegboard 11, the hangers 32 thereof can be loaded as follows. First, the travel stop 64 on the pegboard 11 is adjusted by use of an Allen-head wrench until the threaded body thereof is advanced to its extreme forward position such that the outer end of the travel stop is flush with the outer end of the fitting 68. This is the position of the travel stop for normal operation of the display rack 10. Now, then, when the display rack 10 is unlocked by rotating the arm 63 of the lock 27 to the position shown in FIG. 3, the plate 20 may be advanced to a position indicated as 20' in FIG. 4, which simultaneously advances the outer ends of all the rods 42 such that the respective posts 40 are pivoted into the vertical slots 51 of the rods 42 and within the tubular hangers 32, as shown in FIG. 13. The merchandise cards 35 can now be placed on the several hangers 32 as desired. Then, when the operating handle 48 is released, the movable plate 20 returns to its outer position, and the respective posts 40 on the hangers 32 are pivoted to their outwardly projecting position in which they form a barrier to the removal of merchandise cards 35 off the hangers 32.

The display rack 10 is now ready for use. Thus, a customer is able to fully examine the different items of merchandise on the cards at his leisure and without the need for taking up the time of the sales clerk. It is only when the customer is ready to make a purchase that the sales clerk need be present to unlock the lock 27. This enables the sales clerk to then pull up on the operating handle 48 and thereby depress the plate 20 inwardly against the inner end 66 of the travel stop 64, whereby all the retaining posts 40 are pivoted inwardly at the same time so that the desired merchandise card or cards can be removed from any of the tubular hangers 32. Upon releasing the plate 20, the retaining posts 40 are again shifted to their outwardly projecting position and locked upon locking the display rack 10 to prevent inward movement of the plate 20.

When it is desired to relocate a card holding device 30 to a different location on the pegboard 11, it is first necessary to reset the travel stop 64 by use of an Allenhead wrench until the stop 64 is withdrawn to extreme outward position, such that the inner end 66 on the stop 64 is in contact with the inner end of the fitting 68. Now, then, when the display rack 10 is unlocked by rotating the arm 63 of the lock 27, the plate 20 is advanced towards the pegboard 11 to the position indicated by 20" in FIG. 4, so as to advance all the actuating rods 42 of the card holding devices 30 until the knobs 47 on the forward ends thereof are exposed on the front of the hangers 32, as shown for the hanger in FIG. 14. The fastener 69 on the bracket 31 of the holding device 30 to be relocated is then removed. By holding onto the knob 47 the hanger 32 can then be readily tilted upwardly about the ears 33 on the bracket 31 and the card holding device 30 removed from the pegboard 11. The card holding device 30 can then be replaced to another location on the pegboard as shown and previously described in connection with FIG. 6.

It should be noted that when the actuating rod 42 is depressed onto the tubular hanger 32 so that the knob 47 on the end of the rod 42 is exposed, the retaining post 40 is positioned within the slot 51 on the rod 42 and completely enclosed within the front end of the hanger 32. Thus, by locating the slot on the bottom wall of the hanger 32, as the rod is withdrawn from hanger 32, use can be made of gravity to cause the outer end of the post 40 to fall through the slot 65 and be pivoted to its vertical position.

While the illustrated embodiment of the improved display rack .of the present invention has been described and explained in detail, it will be understood that variations and modifications may be made therein without departing from its scope and spirit.
