Title: Adjustable grid mount and related methods

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Application No. 62/371,579, filed on Aug. 5, 2016, which is incorporated herein by reference in its entirety. 
    
    
     FIELD 
     This invention relates generally to product displays and, more particularly, to merchandisers for front-facing product merchandise for displaying and dispensing product to consumers. 
     BACKGROUND 
     Product displays, such as merchandisers, are frequently used in retail environments to display products for sale. It is advantageous for these product displays to be configured to provide consumers easy access to the displayed product as well as facilitate easy reloading by store employees. In addition to ease of use considerations, manufacturers of product displays seek to minimize materials and manufacturing costs associated with the product displays. 
     One problem with conventional merchandisers is that they typically require intricate structures to make them more user friendly to both end consumers and the retail store clerks or associates who stock and/or restock the merchandisers with displayed product. For example, tray or drawer-type merchandisers that pull out like a drawer to assist store associates in stocking/restocking the merchandiser often require intricate structures that are expensive to manufacture, hard to assemble, and often require operation of inconveniently located release mechanisms to get the tray or drawer to slide out from the display for stocking or restocking purposes. 
     In addition, conventional tray or drawer type merchandisers require the displayed product to be pressed against pushers during stocking/restocking which can make the merchandiser harder to stock/restock and can cause damage to the product being stocked/restocked depending on how much force is exerted against the product between the person stocking/restocking the displayed product and the pushers of the merchandiser. 
     While some conventional merchandisers allow flexibility by offering adjustable width side members so that the merchandiser can be used to merchandise products of different size, conventional merchandisers do not allow the merchandiser to be repurposed from displaying one product to two separate products or vice versa. 
     Accordingly, it has been determined that a need exists for improved product display merchandisers that are not only easy to use, for both consumers and store associates, but also minimally expensive to produce and that offer improved features and functions over conventional merchandisers.

Although seven main embodiments are shown, it is understood that features from any one embodiment may be combined with features of other embodiments to come-up with yet further embodiments that are intended to be covered by this disclosure and the following claims despite not being illustrated in a specific drawing figure for same. 
     First Embodiment 
       FIGS. 1A-1M  illustrate an exemplary embodiment of a product display merchandiser  100 , according to some forms of the inventive subject matter. The product display merchandiser  100  includes a tray  102  for holding a product to be displayed. The tray  102  is supported underneath by arms, support members, brackets, or “blades”  116 . The arms  116  include bracket engagement members  112  that attach to a rear support member (not shown), such as a vertical upright of a conventional gondola or other store shelving system. The rear support member can be any suitable support member such as conventional grid-type systems, bar type systems, shelves, etc. The product display merchandiser  100  can also have one or more stabilizers positioned in various locations on the product display merchandiser  100 . For example,  FIG. 1  depicts a stabilizer  114  positioned between the bracket engagement members  112  near the rear of the product display merchandiser  100 . In some embodiments, the product display merchandiser  100  can include a stabilizer, in addition to or in lieu of the stabilizer  114 , near the front of the product display merchandiser  100 . The stabilizer  114  (as well as any other stabilizers) can be sized so as to accommodate trays of multiple dimensions. The product display merchandiser  100  can also include a lens  106  for holding and displaying signage, preventing product from falling out of the tray  102 , etc. Such a lens can be formed from any suitable material and in any suitable manner. For example, the lens can be extruded or injection molded plastic. Additionally, in one form, the lens can have perforations which allow for easy snap-off type custom-sizing of the lens. 
     In use, the product display merchandiser  100  has multiple positions. In one embodiment, the product display merchandiser  100  can have a closed position (best shown in  FIGS. 1A-1B, and 1E-1G ) for presenting product and an open position (best shown in  FIGS. 1H-1K ) for restocking product. In the closed position, a majority of the tray  102  is positioned over top of the arms  116 . In the open position, the majority of the tray  102  is not positioned over top of the arms  116 . The tray  102  travels along the arms  116  from the closed position to the open position in a direction indicated by arrow  126 . As depicted in  FIG. 1 , the tray  102  includes tracks  120  through which the arms  116  extend. The tracks  120  can take any suitable form. For example, the tracks  120  can comprise a number of individual pieces protruding from the tray  102 , a continuous or semi-continuous channel running along the tray  102 , etc. Additionally the tracks  120  (and/or arms  116 ) can include ball bearings or any other suitable friction-reducing mechanism. 
     In some embodiments, the product display merchandiser  100  includes a mechanism that resists movement of the tray  102  between the open and closed positions. Such a mechanism can prevent the tray  102  from moving from the closed position to the open position unintentionally. For example, the product display merchandiser  100  can include a handle  110  (also seen in  FIG. 1K ) with first engagement members  108 . The arms  116  can include second engagement members  104  that are complimentary to the first engagement members  108 . Such first engagement members  108  and second engagement members  104  are well-depicted in  FIG. 1E . The engagement members are engaged when the tray  102  is in the closed position. Such engagement resists and/or prevents movement of the tray  102  to the open position. In the embodiment depicted in  FIG. 1 , operation of the handle  110  disengages the engagement members. Such disengagement permits movement of the tray  102  from the closed position to the open position. In one form, the first engagement members  108  disengage from the second engagement members  104  when the handle  110  is displaced in a direction parallel to the movement of the tray  102  across the arms  116  (i.e., in the direction of arrow  126 ). For example, movement of the handle away from the bracket engagement members  112  disengages the first engagement members  108  from the second engagement members  104 . As another example, the handle  110  may displace in a somewhat rotational manner. For example, the handle  110  can be affixed to the tray  102  near a leading edge of the tray (i.e., a portion of the tray opposite the bracket engagement members  112 ). The handle  110  is operated from an end of the handle  110  opposite a side of the handle  110  affixed to the tray  102 . In such embodiments, the handle  110  displaces in a somewhat rotational direction that, for purposes of this specification, can be considered to have a displacement in a direction parallel to the motion of the tray  102  and in a direction perpendicular to the motion of the tray  102 . 
     In one form, the product display merchandiser  100  can include a mechanism that prevents the tray  102  from moving from the open position to the closed position during restocking. For example, the arms  116  and the tracks  120  can include complimentary engagement members that engage when the tray  102  is in the open position. Such engagement members can provide mechanical resistance which must be overcome to move the tray  102  from the open position to the closed position. For example,  FIG. 11  depicts a product display merchandiser  100  with arms having an arm engagement member  144  which engages a track engagement member  136 . When the tray  102  is in the open position, the track engagement member  136  engages the arm engagement member  144  and provides resistance against the tray  102  moving from the open position to the closed positon. In some embodiments, such resistance is physical and is overcome by force being exerted on the tray  102  in a direct of the closed position. In other embodiments, there can be a hook, latch, lever, or other release mechanism which must be utilized to disengage the track engagement members  136  from the arm engagement members  144 . 
     As shown in  FIG. 1B  the product display merchandiser  100  includes a tray  102  and arms  116 . The tray  102  includes tracks  120  through which the arms  116  extend. The tray  102  displaces along the arms  116 . The arms  116  can include bracket engagement members  112  configured to mount to a rear support member (not shown). Although  FIG. 1B  depicts the product display merchandiser  100  configured with bracket engagement members  112  to mount to a rear stabilizer, in some embodiments, the product display merchandiser  100  can be configured to be supported by, attach to, and/or rest on a shelf 
     The tray  102  includes a right sidewall  124  and a left sidewall  126  (also referred to as a “side members” or “wings”), as well as a lens  106 . In some embodiments, as depicted in  FIG. 1B , either (or both) of the right sidewall  124  and the left sidewall  126  are extendable to accommodate product of varying dimensions. The tray  102  of  FIG. 1B  is depicted with the right sidewall  124  extended. In one form, the right sidewall  124  and left sidewall  126  are incrementally extendable. Additionally, the right sidewall  124  and the left sidewall  126  can be individually extendable or mechanically coupled in such a way that extension of one of the right sidewall  124  and the left sidewall  126  cause extension of the other of the right sidewall  124  and the left sidewall  126 . 
     To further increase compatibility with product of varying dimensions, some embodiments of the product display merchandiser  100  include a removable divider  130 . The removable product divider  130  is shown in greater detail in  FIG. 1L . The removable divider  130  can attach to the product display merchandiser  100  in any suitable manner. For example, as shown in  FIG. 1L , the removable divider  130  can include divider protrusions  148  that mate with slots  118  on the tray  102  (as shown in  FIG. 1G ), slots which mate with protrusions on the tray  102 , a bar that mates with a track on the tray  102 , etc. In some embodiments, the removable divider  130  is mountable at multiple locations of varying distance from the right sidewall  124  and the left sidewall  126 . When removed, the product display merchandiser  100  preferably includes a storage space for the removable divider  130 .  FIG. 1M  depicts one example by which the removable divider  130  can be stored onboard the product display merchandiser  100 . In one form, the tray  102  includes a recess on a bottom side of the tray  102  configured to accommodate and store the removable divider  130 . Alternatively or additionally, as depicted in  FIG. 1M , the tray  102  can include clips  150  (or other suitable connectors) which hold the removable divider  130  in a stored position on the product display merchandiser  100 . 
     In some embodiments (as depicted in  FIG. 1F ) a divider  142  (whether or not removable) can take the form of a “T-shape.” A horizontal portion of such divider  142  can form a product support surface  140 . This product support surface  140  can support a portion of product displayed in the product display merchandiser and a second product support surface  138  located on the sidewall can support another portion of the product displayed in the product display merchandiser  100 . 
     The tray  102  also includes pushers  122 . The pushers  122  act to urge product toward the front of the tray  102  (i.e., front face product) making the product easier to access. Although  FIG. 1B  depicts the tray  102  as including pushers  122 , some embodiments of the inventive subject matter do not include pushers  122  to urge product to the front of the tray. For example, instead of pushers  122 , the product display merchandiser  100  may be configured to incline, or mount on an incline, in a manner in which gravitational force is employed to urge product to the front of the tray  102 . Additionally, although  FIG. 1B  depicts a product display merchandiser  100  including two pushers  122 , some embodiments of the inventive subject matter can include fewer than two pushers or more than two pushers. In embodiments that include pushers  122 , the pushers  122  generally comprise a vertical member and a biasing mechanism. The pushers  122  can employ any suitable biasing mechanism, such as a spring, a counterweight, a pulley system, etc. In some embodiments, the pushers  122  include engagement members (e.g., clips, latches, detents, etc.) that engage with complimentary engagement members located on the tray  102 , tracks  120 , and/or arms  116 . The engagement members and the complimentary engagement members act to maintain the pushers  122  in a restocking position when the tray  102  is in an open position. Maintaining the pushers  122  in the restocking position not only makes restocking easier but also helps prevent product from being damaged during the restocking process. In some embodiments, the pushers  122  are maintained at a backmost portion of the tray  102  during restocking. In some embodiments, the engagement members and the complimentary engagement members automatically disengage when the tray  102  is moved from the open position to the closed position. For example, the tray  102 , tracks  120 , and/or arms  116  can include disengagement members that cause disengagement of the engagement members from the complimentary engagement members.  FIGS. 1D, 1H and 1J  depict one embodiment of such engagement and disengagement members.  FIG. 1J  depicts two engagement members  146  coupled to the pushers  122 . Although  FIG. 1J  depicts an embodiment including two pushers  122  and two engagement members  146 , it is not necessary that there be a one-to-one correspondence between the pushers  122  and engagement members  146 . The two engagement members  146  act (in concert with the complimentary engagement members) to maintain the pushers  122  in the restocking position when the tray  102  is in the open position.  FIGS. 1D and 1H  depict a product display merchandiser  100  having disengagement members  132 . In one form, the disengagement members  132  are linearly aligned with the pushers  122  and correspond one-to-one with the pushers  122 , although embodiments exist that do not have either of these features (e.g., one form may have one disengagement member  132  and three pushers  122 ). The disengagement members  132  act to disengage the engagement members  146  and the complimentary engagement members when the tray  102  is moved from the open position to the closed position. Such action by the disengagement members  132  cause the pushers  122  to be automatically removed from the restocking position. In one form, the disengagement members  132  are protrusions that physically contact one or more of the engagement members and the complimentary engagement members to force disengagement of the engagement members and the complimentary engagement members. 
       FIG. 1C  is a front view of a product display merchandiser  100 , according to some embodiments of the inventive subject matter. The product display merchandiser  100  includes a lens  106 . As previously discussed, the lens  106  can hold and/or display signage, prevent product from falling out of the tray  100 , etc. Such a lens can be formed from any suitable material and in any suitable manner. For example, the lens can be extruded or injection molded plastic. Additionally, in one form, the lens can have perforations which allow for easy snap-off type custom-sizing of the lens. Additionally, the lens  106  can have multiple display sections or channels. For example, the lens  106  may have a first display portion  106 A and a second lens portion  106 B. Although  FIG. 1C  depicts lens  106  as having the second display portion  106 B arranged above the first display portion  106 A, many other configuration exist. For example, the lens  106  may have left and right display sections, or any other combination of two or more display sections. 
     The remaining figures and text describe alternative embodiments of a product display merchandiser. For purposes of convenience, items that are similar to those discussed above with respect to  FIGS. 1A-1M  will be referenced using the same last two-digit number but using a first digit corresponding to the figure number simply to distinguish from one another. For example, in  FIG. 1 , the product tray is referred to generally by reference number  102 , while the product tray is referred to as  202 ,  302 , and  402 , in  FIG. 2 ,  FIG. 3 , and  FIG. 4 , respectively. 
     Second Embodiment 
     While  FIGS. 1A-1M  depict a first embodiment of a product display merchandiser  100 ,  FIG. 2  depicts a second embodiment of a product display merchandiser  200 , according to some embodiments of the inventive subject matter. The product display merchandiser  200  includes sidewalls  228 , pushers  222 A and  222 B, bracket engagement members  212 , and a pusher attachment  252 . The pusher attachment  252  attaches to the pusher  222 B to expand the surface area of the pusher  222 B. Additional types of pusher attachments exist. For example, pusher attachments can be designed for specific products, to minimize the surface area of the contact point with a product, to extend the depth of the pusher, etc. Additionally,  FIG. 2  depicts a bracket engagement member  212  that is configured to engage a bar mounted system (not shown). Additionally,  FIG. 2  depicts an embodiment of a product display merchandiser in which a horizontal portion of the sidewall  228  (i.e., the product support  238  portion of the sidewall) is roughly equal in area to a vertical portion of the sidewall  228 . 
     Third Embodiment 
     While  FIG. 2  depicts a second embodiment of a product display merchandiser,  FIG. 3  depicts a third embodiment of a product display merchandiser  300 , according to some embodiments of the inventive subject matter. The product display merchandiser  300  includes a tray  302  that is slidable along arms  316 . The tray  302  includes tracks  320  disposed on the bottom side of the tray  302 . The arms  316  are seated in the tracks  320 . The tray  302  moves in a direction as indicated by arrow  326  from an open position (shown) to a closed position (not shown). When in the open position, a void (or unobstructed opening)  358  is revealed (i.e., the product display merchandiser  300  has a baseless design). The void  358  is bounded on a left side and a right side by arms  416 , on a front side by front stabilizer  354 , and on a rear side by rear stabilizer  356 . The tray also includes pushers  322 A and  322 B which are movable within in the tray  302  and a handle  310 . In some embodiments, the handle  310  is operable to disengage engagement members so as to allow the tray  302  to be moved from the closed position to the open position. In one form, the tray  302  includes a divider  330 / 342 . The divider  330 / 342  can be fixed to the tray  302  or removably attached to the tray  302 . 
     Fourth Embodiment 
     While  FIG. 3  depicts a third embodiment of a product display merchandiser,  FIGS. 4A-4R  depict a fourth embodiment of a product display merchandiser  400  having an extendable tray width. 
       FIG. 4A  is an upper perspective view of a fourth embodiment of the product display merchandiser  400  having adjustable side members  428 , according to some embodiments of the inventive subject matter. The product display merchandiser  400  depicted in  FIG. 4A  has one pusher  422  and movable sidewalls  428 . The sidewalls  428  are extendable from the tray in directions indicated by arrows  426 . Extension of the sidewalls  428  allows for the tray width to be adjusted. The tray also includes first mating members  476  (best shown in  FIG. 4Q ) into which corresponding protrusions  478  (best shown in  FIG. 4R ) can seat to secure the sidewalls  428  in an extended position. In some embodiments, a horizontal portion of the sidewalls  428  includes second mating members (e.g., protrusions  478  extending from the horizontal portion of the sidewalls  428 , as depicted in  FIG. 4R ) which fit into the first mating members  476 . In some embodiments, the second mating members “snapfit” into the first mating members  476 . For example, a person can lift an edge of one of the sidewalls  428  to disengage the second mating members from the first mating members  428 . In one form, the sidewalls  428  are secured to the product display by one or more housing members or cords. Such housing members or cords can prevent the sidewalls  428  from becoming completely detached from the product display merchandiser  400  when disengaged. Once disengaged, the person can slide the sidewall  428  in and out until a desired spacing is achieved. Once the desired spacing is achieved, the person can push the sidewall back into place to reengage the second mating members with the first mating members  476  (i.e., snap the first mating members into the second mating members  476 ). In some embodiments, each of the sidewalls  428  are independently movable. For example, a first of the two sidewalls  428  can be moved, and then a second of the two sidewalls  428  can be moved independently of the first. In other embodiments, the sidewalls  428  can be coupled in such a manner that when one of the two sidewalls  428  is moved, the other of the two sidewalls  428  moves in a corresponding manner. 
     In some embodiments, the product display merchandiser  400  includes linear guides  476 , depicted in  FIGS. 4J and 4K . The linear guides  476  help ensure that the sidewalls  428  travel linearly with respect to the product display merchandiser  400  when moved between positions. In one form, the linear guides  476  are protrusions that are seated in recess disposed in a horizontal portion of the sidewalls  428 . 
     Although  FIG. 4Q  depicts the first mating members  476  as incrementally spaced slots, any suitable mechanism for securing the sidewalls in an extended position may be employed. For example, one continuous aperture extending in a direction parallel to the direction in which the sidewalls  428  extend can be utilized. In such embodiments, any suitable fastener (e.g., a screw and nut combination) can be used to secure the sidewalls in an extended position. For example, a horizontal portion of the sidewalls can include a threaded shaft which protrudes through the continuous aperture. In such embodiments, the sidewall can be secured with a nut fastened to the threaded shaft. Alternatively, the horizontal portion of the sidewall can include an internally threaded aperture and the sidewall can be secured by inserting a screw through continuous aperture into the internally threaded aperture. Although multiple examples are given for the first mating members  476 , numerous additionally possibilities exist and are considered within the scope of the teachings herein. 
     Additionally, although  FIG. 4R  depicts the second mating members  478  as protrusions and the first mating members as incrementally spaced slots, any suitable combination of second mating members  478  and first mating members  476  can be used. For example, the second mating members  478  can be shaped as pegs and the first mating members  476  can take the form of complementarily apertures in which the pegs can be seated. 
       FIG. 4B  is a lower perspective view of the product display merchandiser  400  depicted in  FIG. 4A . As seen in  FIG. 4B , the product display merchandiser  400  includes tracks  420  (also well-depicted in  FIG. 4M ) through which arms  416  extend. The tray  402  is slidable along the arms in a direction as indicated by arrow  426  from a closed position (shown in  FIG. 4E ) to an open position (shown in  FIG. 41 ). 
       FIG. 4B  also depicts a baffle  460  inserted on the underside of the product display merchandiser  400  and secured by a rear baffle mount  462  and a front baffle mount  464 . The baffle  460  can server many different purposes, depending on a shape of the baffle  460 , a material from which the baffle  460  is made, and a position of the baffle  460  within the product display merchandiser  400 . For example, the baffle  460  can server to direct airflow through or around the product display merchandiser  400 . Additionally, in some forms, the baffle  460  can be removably attached to the product display merchandiser  400  by insertion and removal from the rear baffle mount  462  and the front baffle mount  464 . 
     The arms  416 , baffle  460 , rear baffle mount  462 , front baffle mount  464  are well-depicted in  FIG. 4L .  FIG. 4L  also depicts a first tray engagement mechanism  468 A- 468 D which acts to maintain the tray  402  in the closed position. A second tray engagement mechanism  470  (best shown in  FIG. 4M ) mates with the first tray engagement mechanism  468 A- 468 D when the tray is in the closed position. In some embodiments, such as those depicted in  FIG. 4P , the rear baffle munt  462  and insert support surface  414  are integral to the rear stabilizer  456 . Additionally, the rear stabilizer  456  can attach to the arms  416  via stabilizer engagement members  472 . 
     Fifth Embodiment 
     While  FIGS. 4A-4R  depict a fourth embodiment of a product display merchandiser  400  having an extendable tray width or adjustable width feature,  FIGS. 5A-5E  depict a fifth embodiment of a product display merchandiser  500  having an alternate manner for adjusting the width of the side members  528 ,  524  and securing them in position so that they cannot be moved once the merchandiser is stocked with product and installed on a shelf, grid or bar. 
     The product display merchandiser  500  of  FIG. 5  includes a left sidewall  528 , a right sidewall  524 , a tray  502 , arms  516 , a removable divider  530 , a lens  506 , and rear stabilizer  556 . The left sidewall  528  and right sidewall  524  are securable to the tray  502 . The tray  502  mounts to, and is supported, by the arms  516 . In a preferred form, the tray  502  is slidable along the arms  516  to an open or extended position making loading product onto the product display merchandiser  500  easier and in a manner that does not require a separate base structure that the tray slides upon. 
     The positions of the left sidewall  528  and the right sidewall  524  are adjustable or moveable with respect to the tray  502 . Such adjustability or movability allows the distance between the left sidewall  528  and the right sidewall  524  to be adjusted to accommodate products of varying size and dimension. 
     In one form, the left sidewall  528  and right sidewall  524  include tongue engagement portions  582 , e.g., grooves, (as shown in  FIGS. 5B-5C ) that mate with the tongues  576  on the tray  572 . Although  FIGS. 5A-5E  depict the left sidewall  528  and right sidewall  524  as including tongue engagement portions  582 , in some embodiments, the tray  502  can include tongue engagement portions or grooves  582  and the left sidewall  528  and the right sidewall  524  can include the tongues  576 . In yet other embodiments, the tray  502  may have tongue and tongue engagement portions and the sidewalls  524 ,  528  may have tongue engagement portions and tongues that correspond with and/or mate with those on the tray  502 . In any of these embodiments, the tongues  576  mate with the tongue engagement portions or grooves  582  to secure the left sidewall  528  and the right sidewall  524  in a desired positon on tray  502 . In the embodiment shown in  FIG. 5E , the tongues  576  are formed into the tray  502  and include a raised portion that engages the tongue engagement portions of the left sidewall  528  and the right sidewall  524 . The tongues  576  are deformable (e.g., can be pushed from a first, resting position to a second, deformed positon) to disengage from the tongue engagement portions  582  and allow the position of one or more of the left sidewall  528  and the right sidewall  524  to be adjusted. 
     In one form, the tongues  576  and/or tongue engagement portions  582  can include a mechanism (e.g., an indexing mechanism) that allows movement of the left sidewall  528  and the right sidewall  524  between predefined or predetermined positions. For example, as depicted in  FIGS. 5A-5E , the tongues  584  include protrusions  584  (e.g., finger members) that seat within the serrated boundaries of the tongue engagement portions  582 . Such embodiments allow for very fine adjustments of the left sidewall  528  and right sidewall  524 . Further, if it is desired to set the width of the sidewalls of numerous merchandisers to the same width setting, this can be done by counting which groove or serration the tongue should be set to and simply setting the protrusion to that serration for each sidewall. To assist in this effort, indicia may be added to one or more serrations or grooves in order to make quick adjustments to that setting on one or many merchandisers. 
     Although  FIGS. 5A-5E  depict tongues  576  as having protrusions  584  and left sidewall  528  and right sidewall  524  as having tongue engagement portions  582  with serrated boundaries, other mechanisms exist for allowing movement of the left sidewall  538  and the right sidewall  524  between predefined positions, such as those depicted and described in  FIG. 4  and the associated text, or any other suitable mechanism. Additionally, in some forms, the left sidewall  528  and right sidewall  524  include sidewall tabs  578  that mate with sidewall tab recesses  580  located on the tray  502  to aid in securing the sidewalls to the tray  502  and ensuring a desired position of the sidewalls is retained. Further, as mentioned above, while various tongue and groove type mating structures may be used to mate the sidewalls to the tray, other types of mating engagements may be used and, of these, they may be alternated so that some appear on both the tray and sidewalls. For example, in some forms, dovetail mating configurations or mortise and tenon mating configurations may be used. In still other forms, other protrusion and mating recess type configurations may be used. 
     In addition to simply providing adjustability, the mechanism described above also helps to ensure that the left sidewall  528  and right sidewall  524  will remain in desired positions after the width of the product display merchandiser  500  has been set. For example, to adjust the position of the left sidewall  528  and the right sidewall  524  the tongues  576  must be manipulated so that they no longer engage the tongue engagement portions  582 . Because the tongues  576  are positioned on the tray  502 , the tongues are not easily accessible when the product display merchandiser  500  contains product. Because the tongues  576  are not easily accessible, it is unlikely that they will be manipulated unintentionally (e.g., by an employee, heavy product, a customer, etc.). Consequently, the left sidewall  528  and right sidewall  524  remain in a relatively fixed position until such position is intentionally altered. Additionally, because the position of the left sidewall  528  and the right sidewall  524  is relatively fixed, some embodiments of the inventive subject matter are able to hold and display heavier products, as it is less likely that such products will cause the left sidewall  528  and the right sidewall  524  to move out of position. This is helpful in avoiding the merchandiser from inadvertently being changed by retailer stocking associates or the like after it has been set or configured in the desired manner to display specific products. 
     In one form, as depicted in  FIG. 5E , the lens  506  of the product display merchandiser  500  may be removable. In such embodiments, the product display merchandiser can include stops, or protrusions,  594 ,  596 . Such stops  594 ,  596  can prevent product from falling out of the product display merchandiser  500  when the lens  506  is removed. The stops  594  can be integral to the tray  502  or left sidewall  528  and right sidewall  524 . The stop  596  can be integral to the tray  502  or the center divider  530  (whether or not the center divider is removable). This allows product in certain situations to be advantageously displayed without a lens so that an unobstructed view of the displayed product may be seen by potential consumers. 
     In the form illustrated in  FIGS. 5A-E  the wings or side members  528 ,  524  preferably will define product support surfaces extending inward toward the opposing side member  528 ,  524  for supporting at least a portion of the displayed product. An example of this product support surface is illustrated in  FIG. 5B  for the left side member  528 . This product support surface runs from the rear of the merchandiser toward the front of the merchandiser and terminates in the protrusions or stops  594 ,  596 . In some forms, the side members  528 ,  524  preferably form stops or abutting surfaces that limit how close the side members  528 ,  524  can be moved toward one another. More particularly, the portions of each side member that define the tongue engagement openings or grooves  582  that protrusions or tongue members  584  engage form distal ends that abut the opposing side member  528 ,  524  to limit the travel of the side members  528 ,  524  toward one another. In the form illustrated, the side members  528 ,  524  contain additional protruding members coplanar with the portions that define the tongue engagement openings  582  that further serve as abutment surfaces that limit travel of the side members  528 ,  524  toward one another. These additional protrusions or protruding members are illustrated for the left side member  528  best in  FIG. 5C  and are positioned between the portions that define the tongue engagement openings  582 . 
     Sixth Embodiment 
     While  FIGS. 5A-5E  depict a fifth embodiment of a product display merchandiser having an alternate manner for adjusting the side members,  FIGS. 6A-6D  depict a sixth embodiment of a product display merchandiser  600  having a mechanism to securely attach a bracket engagement member  612  to a rear stabilizer  656 . The product display merchandiser  600  includes a left sidewall  628 , a right sidewall  624 , arms  616 , a rear stabilizer  656 , a tray, and bracket engagement members  612 . The arms  616  support the tray and are connected to the rear stabilizer  656  via the bracket engagement members  612 . The arms  616  and rear stabilizer  656  connect to the bracket engagement members  612 . For example, in one form, the bracket engagement members  612  can be fastened to the rear stabilizer  656 . The bracket engagement members  612  engage a vertical support (not shown) such as a bar mounted system or a grid mount system from which the product display merchandiser  600  can hang. In the form illustrated, the bracket engagement members  612  and one arm  616  are formed integral to one another as a metal support arm. 
     The bracket engagement members  612  include a locking receiver  686  that mates with a locking protrusion  688  located on the rear stabilizer  656 . The locking receiver  686  and the locking protrusion  688  mate in such a way as to securely affix the bracket engagement member  612  to the rear stabilizer  656 . The locking receiver  686  and the locking protrusion  688  can take any suitable form. For example, the locking receiver  686  can be an aperture through which the locking protrusion  688  extends, a cavity that receives the locking protrusion  688 , a clip to which the locking protrusion  688  attaches, etc. 
     In the example depicted in  FIGS. 6A-6D , the locking protrusion  688  is a piece of material that extends from the rear stabilizer  656 . The locking protrusion  688  can be integral to the rear stabilizer  656  or a separate piece that is attached to the rear stabilizer  656 . The locking receiver  686  can take the form of an aperture located in the bracket engagement member  612 . As depicted in the  FIGS. 6A-6D , the locking protrusion  688  and the locking receiver  686  are similarly shaped (or correspond in shape) and have a slightly different orientation (e.g., approximately 45° out of alignment). The locking protrusion  688  and the locking receiver  686  can take any suitable shape. In the example depicted in  FIGS. 6A-6D , the locking protrusion  688  and the locking receiver  686  are cross-shaped. In such embodiments, the bracket engagement member  612  is placed onto the rear stabilizer  656  in a first position such that the locking receiver  686  and the locking protrusion  688  are oriented in a similar direction. Once the engagement bracket  612  has passed the locking protrusion  688 , the bracket engagement member  612  can be rotated to a second position, the second position being a display position for the product display merchandiser  600 . Once in the second position, the locking protrusion  688  acts on the bracket engagement member  612  to securely hold the bracket engagement member  612  and the rear stabilizer  656  together. For example the locking receiver  686  may fit behind a larger portion of the locking protrusion  688  in such a manner as to experience a clamping force or camming force between an inner surface of the locking protrusion  688  and the rear stabilizer  656 . 
     In the form illustrated, the protrusions  688  correspond in shape with the locking receiver opening  686  so that the protrusion may be orientated into a position to be inserted into the opening  686 . The protrusion  688  further defines a cutout, channel or groove that the locking receiver may be aligned with and then one or both the rear stabilizer  656  and integrated arm  616  and engagement member  612  are moved with respect to each other to securely clamp or fasten the integrated arm  616  and engagement member  612  to one end of the stabilizer  656 . The same process is then repeated with the protrusion located on the opposite end of the stabilizer  656 . In a preferred form, the cutout, channel or groove, is configured to either cam against the engagement member  612  or form a friction fit with the engagement member  612 . Thus, once fully assembled, the three pieces (i.e., rear stabilizer and support arms/engagement members  612  are securely connected to one another to minimize play between each item. 
     Additionally, in some embodiments, the rear stabilizer  656  can include an alignment protrusion  692  and the bracket engagement member  612  can include a mating alignment recess  690 . The alignment protrusion  692  and the alignment recess  690  can be positioned in such a manner as to engage when the bracket engagement member  612  is in the second position. The alignment protrusion  692  and alignment recess  690  can aid in assembly of the product display merchandiser  600  and provide greater stability to the product display merchandiser  600 . In a preferred form, the mating alignment recess  690  and protrusion  692  correspond in shape (e.g., both are circular or other curved structures, rectangular or triangular or other polygonal structures, etc.). In addition, while the illustrated rear stabilizer  656  having protrusions  692  on opposing sides of the stabilizer and, thus, the respective engagement members  612  each have a mating recess  690 , it should be understood that in alternate forms, only one side of the stabilizer  656  may include a protrusion and only one bracket engagement member  612  will include a mating alignment recess. 
     Similarly, although  FIGS. 6A-6D  depict the rear stabilizer  656  as having the locking protrusions  688  and the bracket engagement member as having the locking receiver  686 , embodiments are not so limited. For example, in one form, the rear stabilizer  656  can include the locking receiver  686  and the bracket engagement member  612  can include the locking protrusion  688 . Similarly, in some embodiments, the bracket engagement member  612  can include the alignment protrusion  692  and the rear stabilizer  656  can include the alignment recess  690 . Additionally, although many of the figures (including  FIGS. 6A-6D ) depict the arm  616  and the bracket engagement member  612  as a single piece, in some embodiments, the arm  616  is separate from, and attachable to, the bracket engagement member  612 . 
     Similarly, while this engagement has been described as requiring the engagement bracket  612  to be moved or rotated, it should be understood that in the illustrated embodiment, the engagement bracket  612  does not have to move, but rather the rear stabilizer  656  could alternatively be moved or, in yet other forms, both could be moved with respect to each other. The point being that via some movement of either the engagement bracket  612  and/or the stabilizer  656 , the two items are moved from a first position wherein the two items can be removed from one another or connected to one another, and then be moved to or toward a second position wherein the two items are secured to one another via a clamping or camming force or other fastening engagement. This same procedure can be done for the protrusion  688  extending from the opposite side of the stabilizer and the other integrated engagement bracket and support arm illustrated on the opposite side of the stabilizer  656 . 
     Seventh Embodiment 
     While  FIGS. 6A-6D  depict a sixth embodiment of a product display merchandiser having a mechanism to securely attach a bracket engagement member to a rear stabilizer,  FIGS. 7A-7B  depict a product display merchandiser  700  in which one or more of the product display merchandiser&#39;s  700  sidewalls is removable. The product display merchandiser  700  includes a tray  702 , a left sidewall  728  attached to the tray  702 , and arms  716 . The tray  702  is slidable along the arms  716  from a first retracted or closed position (depicted in  FIG. 7A ) to an open, or extended positon (depicted in  FIG. 7B ). The product display merchandiser  700  can also include a right sidewall (not shown). In the embodiment depicted in  FIGS. 7A-7B , the right sidewall has been removed from the product display merchandiser  700 . In such a configuration, two or more product display merchandiser  700  can be mounted adjacent to one another so as to utilize one or more sidewalls of an adjacent product display merchandiser(s). For example, all product display merchandisers  700  in an arrangement of product display merchandisers  700  may have their right sidewalls removed (except for the rightmost product display merchandiser). In such a configuration, product presented in a product display merchandiser  700  will be supported on the left by the left sidewall  728  of the product display merchandiser  700  and on the right by the left sidewall of the right-adjacent product display merchandiser. In such embodiments, the tray  702  and one or more of the left sidewall  728  and the right sidewall can be designed in a complimentary manner such that the tray  702  and the left sidewall  728  and/or right sidewall create a continuous or nearly continuous surface. 
     Not only does such a configuration allow product display merchandisers  700  to be placed in closer proximity to one another, but also decreases difficulty in loading the product display merchandisers  700 . For example, most product display merchandisers have two sidewalls and a base, allowing product stocking to be performed only from above the product display merchandiser (e.g., top loading of the merchandiser). In embodiments in which the product display merchandiser  700  includes sidewalls that are removable, product can be stocked from the side (in addition to from above) (e.g., side loaded vs. top loaded). 
     Additionally, product display merchandisers that have removable sidewalls can be configured to have interchangeable sidewalls. For example, sidewalls that are different heights, different widths, made of different materials, different shapes, different colors, etc. may be useful for different products or uses. For example, product display merchandisers can be repurposed for different applications or products by changing the removable/interchangeable sidewalls. 
     Eighth Embodiment 
     While  FIGS. 7A-7B  depict a product display merchandiser  700  in which one or more of the product display merchandiser&#39;s  700  sidewalls is removable,  FIGS. 8A-8F  depict a product display merchandiser  800  in which the product display merchandiser  800  can be adjusted vertically relative to the mounts or engagement members  812 . The arms  816  are slidably or movably attached to the engagement members  812 . The engagement members  812  have one or more protrusions  899  extending out both sides. The arms  816  have corresponding openings  898  that are configured to receive the protrusions  899 . Alternatively, the openings  898  could be in the engagement members  812  and the corresponding protrusions  899  could be inward facing on the arms  816 . 
     The openings  898  are arc shaped such that the engagement members  812  must move towards the front of the product display merchandiser  800  (to the left in  FIGS. 8C-8F ) in order to traverse the length of the openings  898 . In alternative embodiments, the openings  898  have shapes other than arcs. Example shapes include, but are not limited to, wedge shapes, vertical slots, or  3  sided square slots. 
     The product display merchandiser  800  has a first vertical position and a second vertical position. In the first vertical position, as shown in  FIGS. 8C-8D , the protrusions  899  are positioned at the bottom of the openings  898 . In the second vertical position, as shown in  FIGS. 8E-8F , the protrusions  899  are positioned at the top of the openings  898 . The product display merchandiser  800  is movable between the first and second vertical positions by moving the arms  816  relative to the engagement members  812  so that the protrusions  899  travel along the length of the openings  898 . 
     As shown  FIGS. 8D, 8F  when the product display merchandiser  800  is in either the first vertical position or the second vertical position the back of the arms  816  are adjacent to the front of the slots in the engagement members  812  that receive the grid when the product display merchandiser  800  is mounted. As such, the grid prevents the engagement member  812  from moving forwards relative to the arms  816  and thus prevents the product display merchandiser  800  from being moved between the first and second vertical positions. 
     In one form, the first and second vertical positions are separated by a distance less than the distance between adjacent cross members of the grid. In one example, the horizontal members of the grid are separated by a primary increment, such as 1 inch. The distance between the first and second vertical positions is equal to a smaller, secondary increment, by which the primary increment is evenly divisible. For example, if the primary increment is 1 inch, the secondary increment is ½ inch. 
     The arms  816  are held from sliding off of the protrusions  899  by the locking protrusion  888  and locking receiver  886  described in the sixth embodiment above. In order to remove the arms  816  from the engagement members  812  the product display merchandiser  800  is rotated relative to the arms  816  until the locking protrusion  888  aligns with the locking receiver  886  at which point each of the arms  816  can be moved outwards relative to the product display merchandiser  800  and the engagement means  812 . In alternative embodiments, the protrusions  899  could face in the same direction from each of the engagement members  812  (as opposed to facing outward as shown) such that the product display merchandiser  800  could be positioned onto the engagement members  812  by sliding over the protrusions  899  from one side. In these embodiments the locking protrusion  888  and locking receiver  886  are removed. 
     In alternative embodiments, the shape of the openings  898  are changed so that the product display merchandiser  800  can be moved from the first vertical position to the second vertical position while the engagement members  812  are engaged to the grid. The openings  898  would be mirror images of those shown in  FIGS. 8A-8F  such that the product display merchandiser  800  moves towards its front end (to the left in  FIGS. 8C-8F ) when moving out of the first or second vertical position. In this embodiment, the arms  816  are locked against movement relative to the engagement means  812  so that the product display merchandiser  800  does not inadvertently fall from the first position to the second position. The lock can be active or passive. Example passive locks include a deformable portion of the openings  898  such that the protrusions  899  snap into the first and second positions or an opening  898  and protrusion  899  having a high coefficient of friction such that a certain initial force is required to transition the product display merchandiser  800  between the first and second positions. Alternatively, the openings  898  could be shaped so that gravity holds the product display merchandiser  800  in the second position. This is achieved by shaping the openings  898  such that the product display merchandiser needs to move up or at least straight horizontal in order to leave the first and second positions. Example active locks include a latch or pin that can be disengaged by the user before transitioning the product display merchandiser  800 . 
     In further alternative embodiments, the product display merchandiser  800  has more than two vertical positions. The shape of the openings  898  are changed such that there are at least 3 positions at the correct horizontal position. Example shapes include a vertical sine wave, a sideways m or w shape, a zig zag shape, or a vertical slot. The vertical slot embodiment is infinitely adjustable by positioning the product display merchandiser  800  wherever desired within the slot and then engaging a locking mechanism or clamping mechanism to prevent it from sliding down under the force of gravity. 
     The features of any of the other embodiments included in this application can be combined with the openings  898  and protrusions  899  of the present embodiment in any combination.
