Title: Removable product support bar display apparatus and method

Description:
BACKGROUND OF THE INVENTION  
     Field of the Invention  
      The present invention relates generally to display devices for supporting packaged products each having a product support aperture located near the top thereof, and more particularly to an improved product support bar display apparatus having display bars which may be removed to allow new packaged products on the proximal end thereof behind older packaged products without first having to remove the older packaged products from the display bar.  
      A wide variety of peg bars devices have been used to display products which are being offered for sale. At a minimum, such peg bar display devices have an elongated peg or rod which is mounted on a pegboard, from a display case, or on a mounting bracket. Over time, they have evolved into more sophisticated and complex configurations. For example, U.S. Pat. No. 5,580,017, to Larson, shows a display apparatus having an elongated peg with a mounting end which is flattened for mounting in an elongated rectangular channel having oval apertures located therein. The elongated peg has an L-shaped leg mounted thereupon which extends above and in parallel to the elongated peg, with the L-shaped leg being used to support a price display member above the end of the elongated peg. Products having a product support aperture located therein can be supported for display from the elongated peg. U.S. Pat. No. 5,580,017 is hereby incorporated herein by reference in its entirety.  
      Such peg bar display devices have been used in a wide variety of applications to display products for sale therefrom. One such application is the display of food products such as cheese and meats in a refrigerated case. An example of this application is found in U.S. Pat. No. 6,959,560, to Weikel et al., which shows a refrigerated display case having a peg bar support system. The refrigerated display case has support bars mounted horizontally inside the case, with pairs of parallel rods extending from each of the support bars. Packages of products having product support apertures are mounted on the lower rods, and a horizontal tag mounting member is attached to the free ends of the upper rods, with pricing and other information being located on the tag mounting member.  
      It will be appreciated by those skilled in the art that products which are located in a refrigerated case will typically have product expiration dates, and if a refrigerated product is not sold before its expiration date it will be removed from sale and either thrown out or returned to the manufacturer. In either case, there is a substantial incentive to ensure that such products are sold rather than being allowed to expire. With most peg bar systems in use at the present time, older products on the peg bars must be removed to allow newer products to be placed on the peg bar. After the newer products are placed on the peg bar, the older products can then be returned to the peg bars, thereby placing the older products in front where they will be sold before the newer products are sold. Unfortunately, with currently-known peg bar display devices, it is far easier to add additional and newer products to the end of the peg bar, thereby placing the oldest products in the back and increasing the likelihood that they will not be sold prior to their expiration date.  
      One of the only solutions to this problem other than to remove the older products by hand is found in U.S. Pat. No. 5,901,860, to Nowicki, which uses a stocking rod which has a tip which is placed onto the free end of a peg bar, with the older products on the peg bar then being moved from the peg bar onto the stocking rod. Newer products can them be placed onto the peg bar, after which the stocking rod can be used to replace the older products on the peg bar in front of the newer products. While the Nowicki patent certainly represents an easier and quicker way to restock the peg bar with the older products being placed in front for first sale, it still requires the removal and subsequent replacement of the older products on the peg bar.  
      Other proposed solutions have only focused on movement of the older products to the front of the peg bar display. For example, U.S. Pat. No. 6,131,748, to Kawasaki et al., and U.S. Patent Application Publication Nos. 2005/0040122 and 2005/0077257, both to Ahlund et al., each focus on moving products located on a peg bar from the rear to the front of the peg bar. These designs thus are of no assistance in dealing with the problem being contemplated herein of adding newer products to a peg bar containing older products. One other variation on the design of peg bars is found in U.S. Pat. No. 3,638,801, to Larson, which shows spaced-apart parallel arms which are adjustable in length, thereby allowing the device to be shortened to place remaining products near the front end thereof. This design also is not helpful to the problem being contemplated herein.  
      It is accordingly the primary objective of the present invention that it facilitate the addition of newer products to a display bar without requiring the prior removal of older products previously contained on the display bar therefrom. It is a related objective of the present invention that it does not require the use of a tool or any other additional apparatus to add the newer products to the display bar behind the older products which are already suspended from the display bar. It is a further objective of the present invention that it be adaptable to work with any of the wide variety of packaged products which are presently displayed from a peg bar type display apparatus.  
      It is another objective of the present invention that it may be used in refrigerated display cases, and that in such an application it will not block the airflow within the refrigerated case that such a refrigerated application requires. It is yet another objective of the present invention that it provide a price display in close association with product suspended from the display bar, and that the price display does not interfere in any way with the addition of new products to the display bar. It is still another objective of the present invention that it not require additional room to implement, thereby not reducing the number of products which can be displayed and offered for sale from a predetermined location.  
      The product support bar display apparatus of the present invention must also be of construction which is both durable and long lasting, and it should also require little or no maintenance to be provided by the user throughout its operating lifetime. In order to enhance the market appeal of the product support bar display apparatus of the present invention, it should also be of inexpensive construction to thereby afford it the broadest possible market. Finally, it is also an objective that all of the aforesaid advantages and objectives of the product support bar display apparatus of the present invention be achieved without incurring any substantial relative disadvantage.  
     SUMMARY OF THE INVENTION  
      The disadvantages and limitations of the background art discussed above are overcome by the present invention. With this invention, a pair of support bars are mounted in side-by-side fashion onto a mounting member located at the rear of a display case or a wall. In applications where there will be a plurality of the product support bar display apparatus installed in close proximity, a horizontal mounting member will typically be mounted between spaced-apart vertical mounting standards located on the rear wall of the display case or on a wall. The support bars thus extend outwardly, with the ends of the support bars which are mounted to the horizontal mounting member being referred to as the proximal ends of the support bars, and the outwardmost ends of the support bars being referred to as the distal ends of the support bars.  
      In the preferred embodiment, a sign rail is mounted onto the distal ends of the support bars, and typically extends across several pairs of support bars. The sign rail is adapted to receive the distal ends of the support bars therein, and to be retained thereupon. Prices for the various objects to be displayed from the product support bar display apparatus may have their prices and additional information contained on small cards which are clipped onto or adhesively secured to the sign rail, where the prices and other information will be displayed immediately above the products which are suspended from the product support bar display apparatus.  
      A display bar carriage is moveably supported by the support bars, and is free to move between a first position adjacent the horizontal mounting member and a second position adjacent the sign rail at the distal ends of the support bars. The display bar carriage is free to move between the first and second positions on the support bars. The display bar carriage will be normally located in the first position when the product support bar display apparatus of the present invention is in use to display products which are suspended therefrom.  
      A display bar is removably mounted from the display bar carriage in a position under the support bars upon which the display bar carriage is moveably mounted. The end of the display bar which is mounted onto the display bar carriage is referred to as the proximal end of the display bar, and the outwardmost end of the display bar is referred to as the distal ends of the display bar. When the display bar is mounted from the display bar carriage, it will be essentially parallel to the support bars upon which the display bar carriage is mounted. The display bar is mounted a sufficient distance below the support bars to allow bags of product having a product support aperture located near the top thereof to be mounted on the display bar, and easily accessed by a customer to remove a bag of product from the display bar. In the preferred embodiment, the distal end of the display bar is upwardly angled.  
      When the display bar has had its supply of bags of packaged product sufficiently diminished, it will need to be restocked. Typically, there will be some remaining bags of product on the display bar, which bags of product will typically be older than additional bags of product to be added to the display bar. To restock the display bar, the display bar carriage will be moved from its first position adjacent the horizontal mounting member to its second position adjacent the sign rail. When the display bar carriage is in this second position, the display bar will extend outwardly with its distal end being located under the back side of the sign rail.  
      The display bar is temporarily removed from the display bar carriage without removing the bags of product which are hanging from the display bar. Additional bags of product are put onto the display bar from the proximal end thereof to restock the display bar with bags of products. The distal end of the display bar is them remounted onto the display bar carriage, and the display bar carriage is returned to its first position adjacent the horizontal mounting member. The older bags of product which were previously on the display bar will be at the front nearer the distal end of the display bar, and the newly stocked bags of product will be located neared the distal end of the display bar behind the older bags of product.  
      While in the preferred embodiment two support bars are used for each product support bar display apparatus, alternatively, a single support member could instead be used. Such a single support member may be wider than it is high, for example. The two support members may also be attached together at the distal ends thereof in a U-shaped configuration.  
      The display bar carriage of the preferred embodiment is made of a segment of rectangular channel material. In the preferred embodiment, the display bar has a flattened longitudinal zone which is located near the proximal end thereof, and the display bar carriage has an oval hole located therein in the front side thereof and a corresponding circular hole located in the rear side thereof. Thus, the proximal end is inserted through the oval hole until the proximal end exits the display bar carriage in the circular hole. The display bar is then rotated ninety degrees and it will be retained in position in the display bar carriage. If desired, a spring member may be placed inside the display bar carriage to engage the flattened longitudinal zone of the display bar and retain it in its engaged position.  
      It may therefore be seen that the present invention teaches a product support bar display apparatus which facilitates the addition of newer products to a display bar without requiring the prior removal of older products previously contained on the display bar therefrom. The product support bar display apparatus of the present invention does not require the use of a tool or any other additional apparatus to add the newer products to the display bar behind the older products which are already suspended from the display bar. The product support bar display apparatus of the present invention is adaptable to work with any of the wide variety of packaged products which are presently displayed from a peg bar type display apparatus.  
      The product support bar display apparatus of the present invention may be used in refrigerated display cases, and that in such applications it will not block the airflow within the refrigerated case that such a refrigerated application requires. The product support bar display apparatus of the present invention provides a price display in close association with product suspended from the display bar, and the price display does not interfere in any way with the addition of new products to the display bar. The product support bar display apparatus of the present invention does not require additional room to implement, and thereby does not reduce the number of products which can be displayed and offered for sale from a predetermined location.  
      The product support bar display apparatus of the present invention is of a construction which is both durable and long lasting, and which will require little or no maintenance to be provided by the user throughout its operating lifetime. The product support bar display apparatus of the present invention is also of inexpensive construction to enhance its market appeal and to thereby afford it the broadest possible market. Finally, all of the aforesaid advantages and objectives of the product support bar display apparatus of the present invention are achieved without incurring any substantial relative disadvantage.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
      The preferred embodiment of the product support bar display apparatus of the present invention is illustrated in an exploded view in  FIG. 1 . The product support bar display apparatus is shown as being mounted onto two spaced-apart vertical mounting standards  30  and  32 . Typically, such mounting standards are used both in display cases and as mounting brackets from mounting display apparatus to walls as well.  
      A horizontal mounting member  34  is mounted between the vertical mounting standards  30  and  32 . The left end of the horizontal mounting member  34  is mounted to the vertical mounting standard  30  with a mounting bracket  36 , and the right end of the horizontal mounting member  34  is mounted to the vertical mounting standard  32  with a mounting bracket  38 . The mounting bracket  36  is attached to the vertical mounting standard  30  using two bolts  40  and  42 , and two nuts  44  and  46 , respectively. Similarly, the mounting bracket  38  is attached to the vertical mounting standard  32  using two bolts  48  and  50 , and two nuts  52  and  54 , respectively. Other types of mounting of the horizontal mounting member  34  may be used without departing from the teachings and principles of the present invention.  
      In the preferred embodiment, the horizontal mounting member  34  may be a segment of rectangular channel material having pairs of apertures respectively located in the front and rear sides thereof. Referring for the moment to  FIG. 8  in addition to  FIG. 1 , it may be seen that there are a series of spaced-apart oval apertures  56  located in the front side of the horizontal mounting member  34  (the side facing away from the vertical mounting standards  30  and  32 ). Alternately, the oval aperture  56  may be D-shaped instead of oval, with the flat side of the “D” being oriented downwardly and the rounder side of the “D” being oriented upwardly. There are a corresponding series of spaced-apart circular apertures  58  located in the rear side of the horizontal mounting member  34 .  
      The orientation of the oval apertures  56  in the horizontal mounting member  34  are with the longer side oriented vertically (orthogonally to the longitudinal axis of the horizontal mounting member  34 ). The oval apertures  56  and the apertures  58  are located in the horizontal mounting member  34  such that the bottoms of the oval apertures  56  are located slightly higher than the bottoms of the apertures  58 , as best shown in  FIGS. 8 and 12 . This will result in a slightly upward pitch of an article mounted in one of the oval apertures  56  and a corresponding one of the apertures  58 .  
      Referring again to  FIG. 1 , the horizontal mounting member  34  serves to support a pair of support bars  60  and  62 , which are identical in their configurations. The ends of the support bars  60  and  62  which are supported from the horizontal mounting member  34  are referred to herein as their proximal ends, and the ends of the support bars  60  and  62  which are furthest from the horizontal mounting member  34  are referred to herein as their distal ends. The support bars  60  and  62  have flattened longitudinal zones  64  and  66 , respectively, which are located near the proximal ends thereof. The flattened longitudinal zones  64  and  66  have flat top and bottom sides, and are wider than the width of the rest of the support bars  60  and  62 .  
      The support bars  60  and  62  are mounted in the horizontal mounting member  34  by inserting their proximal ends into the horizontal mounting member  34  through the oval apertures  56 , and then locating their proximal ends in the apertures  58  in the horizontal mounting member  34 . When the support bars  60  and  62  are inserted into the horizontal mounting member  34 , the flattened longitudinal zones  64  and  66 , respectively, are vertically oriented. After the support bars  60  and  62  have been inserted into the horizontal mounting member  34 , the flattened longitudinal zones  64  and  66 , respectively, are rotated ninety degrees so that they are horizontally oriented. The support bars  60  and  62  will then be retained in this position in the horizontal mounting member  34 .  
      Those skilled in the art will realize that different types of mounting apparatus can be used instead of the vertical mounting standards  30  and  32 , the horizontal mounting member  34 , and the flattened longitudinal zones  64  and  66  on the support bars  60  and  62 , respectively. Once the support bars  60  and  62  have been mounted in the horizontal mounting member  34 , they will remain in place as long as the product support bar display apparatus of the present invention is used.  
      A display bar carriage  68  is slidably mounted on the support bars  60  and  62 . The display bar carriage  68  shown in  FIG. 1  is made from a segment of rectangular channel material. The display bar carriage  68  has two spaced-apart apertures  70  and  72  (best shown in  FIG. 9 ) located in the rear side thereof near the top thereof, and two corresponding spaced-apart apertures  74  and  76  located in the front side thereof near the top thereof. The display bar carriage  68  is mounted on the support bars  60  and  62  by inserting the distal end of the support bar  60  through the apertures  70  and  74 , and by inserting the distal end of the support bar  62  through the apertures  72  and  76 .  
      There is an oval aperture  78  located in the front side of the horizontal mounting member  34  longitudinally between the apertures  74  and  76 , and near the bottom thereof. There is a corresponding circular aperture  80  located in the rear side of the display bar carriage  68  longitudinally between the apertures  70  and  72 , and near the bottom thereof. The orientation of the oval aperture  78  in the display bar carriage  68  is with the longer side oriented vertically (orthogonally to the longitudinal axis of the display bar carriage  68 ).  
      The display bar carriage  68  serves to support a display bar  82 . The end of the display bar  82  which is supported from the display bar carriage  68  is referred to herein as its proximal end, and the end of the display bar  82  which is furthest from the display bar carriage  68  is referred to herein as its distal end. The display bar  82  has a flattened longitudinal zone  84  which is located near the proximal end thereof. The flattened longitudinal zone  84  has flat top and bottom sides, and is wider than the width of the rest of the display bar  82 . The flattened longitudinal zone  84  of the display bar  82  is illustrated in  FIG. 2 . The flattened longitudinal zones  64  and  66  of the support bars  60  and  62 , respectively, are identical in configuration to the flattened longitudinal zone  84  of the display bar  82 .  
      The distal end of the display bar  82  has an upwardly angled end  86 , which extends approximately below the levels of the distal ends of the support bars  60  and  62 . The display bar  82  is also mounted approximately parallel to the support bars  60  and  62 . A bag of packaged product  88  has a product support aperture  90  centrally located near the top edge thereof. The bag of packaged product  88  will be mounted on the display bar  82  by inserting the upwardly angled end  86  of the display bar  82  through the product support aperture  90  of the bag of packaged product  88 , and sliding the bag of packaged product  88  onto the display bar  82 . Thus, the vertical distance between the display bar  82  and the support bars  60  and  62  must be sufficient to allow the bag of packaged product  88  to fit easily onto the display bar  82  without contacting the support bars  60  and  62 .  
      Referring now to  FIG. 7  in addition to  FIG. 1 , completing the product support bar display apparatus of the present invention is a sign rail  92  which has a bracket  94  located at the rear thereof with a series of apertures  96  located in the rear side thereof into which the distal ends of the support bars  60  and  62  are inserted and retained. The distal ends of the support bars  60  and  62  are shown as being peened to retain them in the bracket  94 , but any other suitable retention method may be used instead. Located on the front side of  92  is a sign retention area  98  into which preprinted signs  100  showing the price of the bag of packaged product  88 , and optionally additional information regarding the bag of packaged product  88 , may be placed.  
      Referring next to  FIG. 3 , the installation of a row of four of the product support bar display apparatus described above with regard to  FIG. 1  is illustrated into a display case  102 . The lateral spacing of the product support bar display apparatus in the display case  102  is determined by the width of the bags of packaged product  88  being displayed thereupon. As such, wider bags of packaged product  88  will require greater spacing between adjacent product support bar display apparatus. Although not shown in  FIG. 3 , those skilled in the art will appreciate that the vertical distance between rows of the product support bar display apparatus will be determined by the height of the bags of packaged product  88  being displayed thereupon.  
      Referring next to  FIGS. 4 through 7 , the row of four of the product support bar display apparatus described above with regard to  FIG. 1  is shown in detail, with the display bar carriage  68  being shown in a first position adjacent the horizontal mounting member  34 . When the display bar carriage  68  is in its first position, it may be seen that the upwardly angled end  86  of the display bar  82  extends to a location below and just behind the sign rail  92 . In addition, it may be seen that the display bar  82  is essentially parallel of the support bars  60  and  62 . This first position of the display bar carriage  68  and the display bar  82  is used when the bags of packaged product  88  are being displayed for sale upon the product support bar display apparatus.  
      Referring now to  FIGS. 8 and 9 , the engagement of the flattened longitudinal zones  64  and  66  of the support bars  60  and  62 , respectively, with the horizontal mounting member  34  and the engagement of the flattened longitudinal zone  84  of the display bar  82  with the display bar carriage  68  are shown. In  FIGS. 8 and 9 , the support bars  60  and  62  are shown in their engaged positions with respect to the horizontal mounting member  34 , in which they will be following assembly of the product support bar display apparatus. The display bar  82  is also shown in its engaged position with respect to the display bar carriage  68 , in which it will be during the normal display of products thereupon. Note also that in  FIG. 8  the display bar carriage  68  is shown in phantom lines as starting to move from its first position in a direction away from the horizontal mounting member  34 .  
      Referring next to  FIGS. 10 and 11 , the display bar carriage  68  is shown suspended from the support bars  60  and  62 . In  FIG. 10 , the display bar  82  is shown in its mounted position with respect to the display bar carriage  68 , with the upwardly angled end  86  being oriented upwardly and the flattened longitudinal zone  84  of the display bar  82  extending laterally in the oval aperture  78 . In this position, the flattened longitudinal zone  84  of the display bar  82  will retain the display bar  82  in position on the display bar carriage  68 . In order to remove the display bar  82  from the display bar carriage  68 , it is rotated ninety degrees as shown in  FIG. 11 , with the upwardly angled end  86  extending in a lateral direction and the flattened longitudinal zone  84  of the display bar  82  being oriented vertically with respect to the oval aperture  78  in the display bar carriage  68 . In this position, the display bar  82  may be removed from the display bar carriage  68 .  
      Referring now to  FIG. 12 , the support bar  62  is shown by the arrow as being rotated ninety degrees to move the flattened longitudinal zone  66  of the support bar  62  from the position in which it is shown in  FIG. 12  to a vertical orientation. In this vertical orientation, the support bar  62  may be removed from the horizontal mounting member  34 . Although it is not shown in  FIG. 12 , the support bar  60  may similarly be rotated to remove it from the horizontal mounting member  34 . Additionally, although it is not shown in the figures, a spring member may be installed inside the horizontal mounting member  34  and the display bar carriage  68  to act against the flattened longitudinal zones  64  and  66  of the support bars  60  and  62 , respectively, and on the flattened longitudinal zone  84  of the display bar  82 .  
      As mentioned above, the product support bar display apparatus of the present invention is shown in  FIGS. 4 through 6  with the display bar carriage  68  in its first position adjacent the horizontal mounting member  34 . In order to load additional bags of packaged product  88  onto the display bar  82  behind older bags of packaged product  88  remaining on the display bar  82 , the display bar carriage  68  and the display bar  82  are moved to a second position as shown in  FIG. 13 . In this second position, the display bar carriage  68  is located adjacent to the rear of the sign rail  92 .  
      From this second position of the display bar carriage  68  and the display bar  82 , the display bar  82  may be rotated ninety degrees and removed from the display bar carriage  68  as shown in  FIG. 14 . Additional new bags of packaged product  104  are then placed on the proximal end of the display bar  82 , and the display bar  82  is then remounted into the display bar carriage  68  by reversing the process used to remove it from the display bar carriage  68 . Thus, it may be seen that the new bags of packaged product  104  are displayed from the display bar  82  in positions which are behind the older bags of packaged product  88  which were previously displayed on the display bar  82 .  
      Referring next to  FIGS. 15 through 18 , an alternate embodiment display bar carriage  110  is shown mounted on two support bars  112  and  114 , which are identical in their configurations. The ends of the support bars  112  and  114  which are supported from the horizontal mounting member  34  are referred to herein as their proximal ends, and the ends of the support bars  112  and  114  which are furthest from the horizontal mounting member  34  are referred to herein as their distal ends. The support bars  112  and  114  project forwardly from the horizontal mounting member  34 , and jog upwardly at a ninety degree angle, and then again extend forwardly following a second ninety degree angle. The proximal end distal portions of the support bar  112  and  114  thus are parallel.  
      The support bars  112  and  114  have flattened longitudinal zones  116  and  118 , respectively, which are located near the proximal ends thereof. The flattened longitudinal zones  116  and  118  have flat top and bottom sides, and are wider than the width of the rest of the support bars  112  and  114 . The support bars  112  and  114  are mounted and retained in the horizontal mounting member  34  in the same manner are the support bars  60  and  62 , and they will remain in place as long as the alternate embodiment product support bar display apparatus of the present invention is used.  
      The display bar carriage  110  consists of a body portion  120  which extends between the support bars  112  and  114 , and two L-shaped arms  122  and  124  which extend from opposite sides of the front segment of the body portion  120 . The L-shaped arm  122  extends over the top and side of the support bar  112  opposite the body portion  120 , and the L-shaped arm  124  extends over the top and side of the support bar  114  opposite the body portion  120 . The L-shaped arms  122  and  124  support the display bar carriage  110  on the support bars  112  and  114 .  
      The display bar carriage  110  uses four pins  126 ,  128 ,  130 , and  132  which extend from the sides of the body portion  120  of the display bar carriage  110  to retain it on the support bars  112  and  114 . The pins  126  and  128  are located on one side of the body portion  120  of the display bar carriage  110  and extend under the support bar  112 . The pins  130  and  132  are located on the other side of the body portion  120  of the display bar carriage  110  and extend under the support bar  114 . All four pins  126 ,  128 ,  130 , and  132  are mounted by screwing them into the side of the body portion  120  of the display bar carriage  110 , and if desired they may have a slot for a screwdriver or a hex aperture for a hex head screwdriver.  
      Located underneath the body portion  120  of the display bar carriage  110  is a segment of rectangular channel material  134 . Two capscrews  136  and  138  extend through the top of the body portion  120  of the display bar carriage  110  and are screwed into the top of the segment of rectangular channel material  134 . There is an oval aperture  140  located in the front side of the segment of rectangular channel material  134 , and a corresponding circular aperture  142  located in the rear side of the segment of rectangular channel material  134 . The orientation of the oval aperture  140  in the segment of rectangular channel material  134  is with the longer side oriented vertically (orthogonally to the longitudinal axis of the segment of rectangular channel material  134 ).  
      The segment of rectangular channel material  134  serves to support the display bar  82  from the display bar carriage  110 . The vertical distance between the display bar  82  and the support bars  112  and  114  are sufficient to allow the bag of packaged product  88  to fit easily onto the display bar  82  without contacting the support bars  112  and  114 . The manner of removing the display bar  82  from the segment of rectangular channel material  134  on the display bar carriage  110  and adding additional new bags of packaged product  104  is the same as described above in conjunction with the embodiment of the product support bar display apparatus shown in  FIGS. 1 through 14 .  
      It may therefore be appreciated from the above detailed description of the preferred embodiment of the present invention that it teaches a product support bar display apparatus which facilitates the addition of newer products to a display bar without requiring the prior removal of older products previously contained on the display bar therefrom. The product support bar display apparatus of the present invention does not require the use of a tool or any other additional apparatus to add the newer products to the display bar behind the older products which are already suspended from the display bar. The product support bar display apparatus of the present invention is adaptable to work with any of the wide variety of packaged products which are presently displayed from a peg bar type display apparatus.  
      The product support bar display apparatus of the present invention may be used in refrigerated display cases, and that in such applications it will not block the airflow within the refrigerated case that such a refrigerated application requires. The product support bar display apparatus of the present invention provides a price display in close association with product suspended from the display bar, and the price display does not interfere in any way with the addition of new products to the display bar. The product support bar display apparatus of the present invention does not require additional room to implement, and thereby does not reduce the number of products which can be displayed and offered for sale from a predetermined location.  
      The product support bar display apparatus of the present invention is of a construction which is both durable and long lasting, and which will require little or no maintenance to be provided by the user throughout its operating lifetime. The product support bar display apparatus of the present invention is also of inexpensive construction to enhance its market appeal and to thereby afford it the broadest possible market. Finally, all of the aforesaid advantages and objectives of the product support bar display apparatus of the present invention are achieved without incurring any substantial relative disadvantage.
