## Background
FIELD OF INVENTION
This application relates to a modular shelving system for use in retail sales, and more particularly to a shelving system which is easily assembled and disassembled while maintaining a high degree of stability and support.
BACKGROUND OF THE INVENTION
In recent years a new type of retail sales store has evolved. At different seasonal times of the year, or for other reasons, a “pop-up” store or other event driven opportunities may open for a limited period of time to sell holiday related items or other specific goods. It is important for such stores to quickly and easily set up and open, and then knock down and close. Traditional shelves and other display fixtures can be difficult and time-consuming to assemble and disassemble. Therefore, there is a need for shelving and display fixtures that can be easily set-up and quickly taken down without leaving holes or nail marks in the walls.
Accordingly, one of the benefits of the subjection invention is a shelf assembly that may be easily and quickly assembled and disassembled by unskilled labor, with no tools.
A further benefit of the subject invention is a shelf assembly that has shelves with adjustable heights, and orientation.
A still further benefit of the subject invention is a shelf assembly that has interchangeable and common parts for easier assembly and less expensive manufacture.
SUMMARY OF THE INVENTION
The subject invention comprises a modular, pop-up shelf display system that includes vertical slotted shelf support posts, horizontal tie bars, and shelf or accessory members. Two slotted support posts are connected at the top and bottom ends by a pair of tie bars; the top of each slotted support post leans against a wall. Shelves or accessories, which include brackets that engage the slots in the vertical support posts are then attached to the support posts to form horizontal shelves or accessories between the support posts at desired heights and orientation. The system includes internal connectors positioned inside the posts ends and the ends of the tie bars to secure the posts in an upright manner against the wall. A free standing shelf system is also envisioned utilizing the slotted support posts, joined by a pair of tie bars.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to FIGS. 1 and 2 there is shown shelf assembly 10 having vertical support posts 20. The supports 20 are secured together in spaced relation by tie rods 30 at an upper and lower location of the shelf assembly 10. Shelves 40 or other accessories, such as hanger rods 17 (FIG. 3), are secured between the vertical supports 20 by brackets 41 on either side of the shelf. Back panel 21 may be a laminated board and serves as a decorative backdrop for the products displayed on the shelf. As such back panel 21 may have decorative designs, as desired. Back panel 21, as best seen in FIG. 2, does not support the shelf assembly, nor does it touch the floor 19.
The vertical support posts 20 lean against the wall at approximately a 10° to 20° angle, and preferably 10°. Each vertical support may have a non-skid foot 22. FIG. 3 shows another embodiment where the shelf assembly 50 is a multi-unit assembly, having interlinked upright supports 20 with tie rods 30 between and connected to adjacent vertical supports 20. Vertical support 20 has two opposing sides with channel slots 18 along the length of the vertical support. These channel slots 18 support the shelves in a manner to be described.
FIG. 3 shows a shelf assembly of the subject invention with multiple sections one of which may support hanger rods 17 or other accessories. As each support post 20 has identical slots and other openings on opposing sides, additional sections can be added without the need for different parts fasteners or tools, thereby contributing to the low cost of equipment and ease of assembly.
FIG. 4 shows the manner of connection of a tie rod 30 to a support post 20. Tie rod insert 31 fits snuggly inside the hollow end of the tie rod 30 and is secured there by pin or screw 36 which is inserted through opening 34 of the tie rod into the insert 31. On an outer end of insert 31 is a peg 32 having oppositely positioned pins 35 extending transverse to the longitudinal axis of peg 32 and tie rod 30.
As best seen FIGS. 10(a) and 10(b), cam lock insert 26 has a central opening 27 with opposing peripheral wing openings 48 on an outer side, and on an inner side cammed surfaces 28. The cammed surfaces comprise an inclined surface as shown in FIG. 10(a). At the start of the inclined plane is a level surface 49 which leads to helical inclined plane 39 and afterwards depression 33 which holds or locks the pins 35 in position.
Situated inside hollow vertical support is support insert block 24, better seen in FIG. 5. Support insert block 24 is sized to fit snuggly inside the hollow end of support post 20 and secured there by a screw or other fastener 42. Insert 24 has a channel or recess 25 into which cam lock insert 26 is located on opposite sides of the insert block 24. Each cam lock 26 has a groove or channel 37 that lines up with a similar channel 38 on the insert, so as not to block openings 27 and 29. In use, the cam locks are placed into the channel and locked in place by the use of spring clip 16 in grooves 37 and 38. The insert 24, with cam locks secured, are then placed into the hollow ends of the support post 20. A tie rod 30 aligns the peg 32 and pins 35 for insertion into and through the central opening 27 of cam lock 26. The tie rod 30 is rotated, causing the pins 35 to engage the cammed surfaces 28, go over the slight ridge 15, into the depression 33, pulling the tie rod into the support post and locking the tie rod into position.
The shelf assembly 40 is shown in FIGS. 6 and 7. Shelf assembly 40 comprises shelf panel 45, accessory support assembly 56 and shelf ledge 44. Accessory support assembly 56 includes shelf support brackets 43 and left and right accessory support brackets 41. Bracket 41, as shown in FIG. 7 has openings 51 and 52. Opening 51 can be a straight slot, while opening 52 may be an L shaped slot having a vertical component and a lower horizontal component. The horizontal component has an enlarged region at the closed end. When the bracket is installed on the shelf sides as in FIG. 6, the bracket angle relative to the shelf can be changed from about 15° to 0° selectively by placement of the fasteners 53 in either extremities of the respective slots. The fasteners 53 secure the bracket 43 to support bracket 41, which may be secured to support posts by insertion of hooks 61 into slots 18 on the support posts. The accessory support brackets 41 slide onto and hold the shelf panel 45 or at the desired angle. The shelf orientation may be reversed to position the shelf ledge at the front of the assembly as desired. Other means for securing the shelf to the support posts while allowing different angled attachments may be used, such as that shown in U.S. Pat. No. 5,749,480.
Shelf ledge 44 may also be hinged to allow movement from a first upward vertical position to a second downward vertical position. As shown in FIG. 11, the shelf ledge 44 may pivot at one end to allow such movement. The shelf ledge would be pivoted to the upward vertical position when the shelf itself was in an angled position, so that objects placed on the shelf cannot roll or otherwise fall off. When the shelf was level or in a horizontal position, the shelf ledge would be pivoted to the downward vertical position and out of the way. In the embodiment of FIG. 11, the shelf panel 45 is enclosed in a monolithic shell, preferably of sheet metal 47. An end panel 46 is secured to the shell 47 by a screw 54 or other fastener which may be self-tapping or engage an embedded nut as shown. Shelf ledge 44 pivotally secured to an upper end of panel 46 so it can pivot from the raised position to the lowered position, as indicated by the arrow. The lowered position may include a recess 58 in the shelf to provide a substantially flat shelf surface, while allowing the shelf ledge to pivot from a substantially horizontal position to a substantially vertical position. Stop 59 may be formed in end panel to restrict the maximum pivotal movement of the shelf ledge 44 to a 90° position from horizontal, i.e., substantially vertical.
In the event a free standing unit was desired, a trapezoid shaped assembly may be used with mitered corners as shown in FIG. 9. A connector assembly similar to that in FIGS. 4 and 5 may be used. As shown in FIG. 8, lower support rail 55 is attached to support posts 20 at opposite ends by angled connector assemblies 60. Similar to insert 24 in FIGS. 4 and 5 both cam lock inserts 26 are seated in recess 25 so that the camming surface 28 is facing the interior. With the cam locks seated in the recess, the right angle connector assemblies are inserted into the hollow ends of both support posts 20 and support rail 55. Screws or pins (not shown) are inserted into holes 57 and 52 to secure the support post 20 and support rail 55 together. A spacer 62 may be used between the support post 20 and support rail 55. A similar construction may be used to attach the upper support rail to the top end of the support post. The same structure is then used to construct the opposite side. A tie rod 30 is then used to connect the two structures at the upper end and the lower end in the same manner as described above. Thus, the tie rod 30 is inserted into opening 23 in both left and right support posts, taking care the peg 32 and pins 35 (FIG. 4) enter the central opening 27 of cam lock 26, with the pins inserted through wing openings 48. The tie rod 30 is then twisted to bring the pins 35 into contact with the camming surface 28 and then locked in position as the pins overcome ridge 15 and seats in the depression 33. Shelves are secured to support posts in a manner similar to the wall leaning shelf described above.
It will be understood that the foregoing description is of preferred exemplary embodiments of the invention and that the invention is not limited to the specific forms shown or described herein. Various modifications may be made in the design, arrangement, and type of elements disclosed herein, as well as the steps of making and using the invention without departing from the scope of the invention as expressed in the appended claims.
