The present invention relates generally to display tables. More particularly, the present invention relates to a display table having at least one adjustably configurable accessory pole or mast that is particularly suitable for use in trade shows, exhibitions and the like.
At tradeshows and other public exhibitions, vendors and salespersons often use collapsible tables to display their products and services. The vendors sometimes bring their own collapsible large banquet-style tables with them if they are traveling by ground and with a vehicle large enough to transport the tables. Alternatively, such tables are often available to vendors by renting them from the facility at which the tradeshow is being held. However, the rental tables are usually expensive to rent. In addition to paying for the tables, the vendors are often also charged for the time and labor that it takes workers to set up and tear down the tables. When the rental tables are not banquet-type tables but rather complex tables requiring some level of assembly, the vendors are usually charged for the time and labor that it takes workers to assemble the tables. Moreover, the rental tables are usually very generic looking and provide no visual impact to tradeshow attendees.
Conventional collapsible banquet-style tables that are commonly used at tradeshows can be seen in U.S. Pat. Nos. 6,550,404, 6,530,331, 6,431,092, and 6,112,674. The banquet-style tables generally have a large horizontal tabletop and legs that fold up and underneath the table surface. The tables are usually very big and heavy and therefore the portability of such tables is severely limited by the large size of the tabletop. Moreover, the banquet-style tables do not have any storage or shelf space nor do they include any customizable skirts or banners. A vendor can tape or clip on a personalized banner, although if the vendor is renting the table, the owner of the venue may not allow such use of the tables.
A collapsible display table that addresses some of the above-listed problems is disclosed in U.S. Pat. No. 5,865,127. U.S. Pat. No. 5,865,127 is directed to a collapsible display table with a truss framework that supports a folding tabletop and a shelf. However, other than the shelf, the table according to the '127 patent does not provide a user with very much storage space. In addition, other than the shroud shown in
In addition to the above-described deficiencies for collapsible display tables, these conventional tables lack desired modularity to provide flexible configurations to selectively attach accessories. For instance, while display systems typically allow for the attachment of appurtenances to the framing of the displays, they do not provide flexible attachment to the display tables. Such conventional configurations, therefore, limit the types of accessories employed with the tables. As these display tables are often the focal point of meetings and conversation during an exhibition or trade show, present systems do not optimize the table space as they do not provide the end user with the ability to selectively present graphics, monitors, literature displays and like hardware and signage at the often visible display tables.
Because the general problems discussed above have not been addressed, there is a current need for a cost-efficient display table that takes up minimal space, that is easily transportable, and that includes an adjustable and multi-configurable accessory attachment system. Such a table would greatly increase the ability of the end user to utilize and uniquely provide configurations in accordance with one's particular needs. For instance, an end user could selectively configure the display table to receive and display various appurtenances, such as monitors, literature materials, banners and the like.
The item of furniture according to the present invention provides a vendor end user with a lightweight table that is easy to set up to an erected state and to collapse to a collapsed state and meets the needs described above.
In preferred embodiments the principal components of the item of furniture are configured as a table and are interconnected and self-contained; the principle components remain part of the assembly in the collapsed state. The table preferably includes the principle components of a tabletop, at least one shelf, a plurality of folding legs and at least one adjustable accessory/appurtenance pole or mast.
The legs are attached to the tabletop and are foldable between an extended and erected position and a folded and transport position or a collapsed state. The one or more shelves are slidably positioned on the legs and have a nested position adjacent to the underside of the tabletop and a use position. In the use position the shelf locks the extended legs in place. A hinge or pivot point on the legs is positionally displaced down the legs from the lower surface of the tabletop a distance approximately the thickness of the shelf or shelves to define a suitable nesting region for the shelves intermediate the folded legs and the underside of the tabletop.
A drawer may be attached to the underside of the tabletop or shelves, providing the vendor with multiple places to store samples, brochures, and other materials during the tradeshows. In preferred embodiments, the tabletop, the shelves, and the drawer may be molded of plastics, for example by blow molding.
In one embodiment, the at least one adjustably configurable accessory pole or mast can include at least an upper post member and a lower post member adapted for telescoping connectivity, and a mounting assembly adapted to connect various appurtenances/accessories to the pole. In addition, the lower post member and upper post member can be attached together in an end-to-end relationship. The mounting assembly can include brackets, fasteners, apertures, and various other components and techniques for connecting a display device (such as a monitor, signage and the like) to the at least one pole.
The at least one pole is preferably tubular and includes access apertures and/or slots for receiving and routing wires and cables therethrough. Further, various mounting and bracket assemblies can be included to connect literature racks, computer monitors, graphics and/or banners and the like, depending on the shape, size and configuration of the particular accessory. In one embodiment, the lower post member telescopes from within the upper member and down through apertures in the table such that the upper post member is positioned to extend up a distance from the tabletop. To facilitate attachment of the accessories to the pole, the upper post member can include a plurality of peripheral channels extending along the longitudinal axis of the pole. Other apertures and components can be utilized as well. Bracket and mounting assemblies can be slidably engaged along the peripheral channels to attach the subject accessory at selected positions along the length of the upper post member. The at least one accessory pole and associated mounting components and assemblies can be implemented with the collapsible table disclosured herein as well as other tables utilized in trade shows, exhibitions and a myriad of other environments.
A feature and advantage of the table is that it is easy to erect and to collapse to the transport configuration by one person.
A feature and advantage of the preferred embodiments of the invention is that the blow or rotationally molded tabletop and shelves provide a lightweight and structurally strong and robust piece of furniture.
A feature and advantage of the invention is that a common mold may be used for different shelves. For example the two shelves below the table top in a preferred embodiment may be identical although one uses circumferential stops on the legs to secure it in place and the other uses the horizontal cross member to secure it in place in the erected state.
A feature and advantage of the preferred embodiment is that the table is inexpensive to manufacture with lower cost materials and minimal labor.
A feature and advantage of the invention is that at least one configurable accessory pole is provided to facilitate the selective attachment of various display devices and appurtenances to the table, such as monitors and signage.
A feature and advantage of the invention is that the at least one accessory pole can be constructed of telescoping post members that facilitate easy assembly, disassembly, handling and transporting of the attachment system.
A feature and advantage of the invention is that the at least one accessory pole is adapted to receive various mounting and bracket assemblies for selectively attaching and positioning graphics and displays, monitors, literature racks, and the like along the length of the extending pole, a distance above a tabletop.
A feature and advantage of the invention is that the mounting and bracket assemblies can be easily implemented, exchanged with other assemblies, and disassembled to promote ease-of-use and flexible configurations for attaching appurtenances and display devices to the display table.
A feature and advantage of the invention is that post members of the at least one accessory pole can be tubular and include wire access apertures and slots to facilitate the selective routing and distribution of wiring therethrough.
By bringing a table according to the present invention, a vendor no longer needs to rent tables at the venue of the tradeshow. Because of its weight and small size in the collapsed state, the table, the accessory pole and the subject appurtenances can easily be transported in the back seat or trunk of a car and can even be brought along on an airplane trip. Without the necessity of having to rent a table, the table according to the present invention is very economical and saves a vendor many rental costs normally associated with attending a tradeshow. In addition, a vendor can use a customizable skirt and the accessory pole on the table that has a visual impact on the tradeshow attendees.
The invention herein is depicted as a table but it is recognized that other configurations such as collapsible podiums or stack of shelves may also suitably incorporate the invention herein.

Referring to the figures, particularly
The shelf bottom surface 142 includes a first support bar cutout 162 and a second support bar cutout 164. The first support bar cutout 162 preferably spans the distance between the first leg aperture 152 and the second leg aperture 154 and is substantially the same size as the first support bar 132. The second support bar cutout 164 spans the distance between the third leg aperture 156 and the fourth leg aperture 158 and is substantially the same size as the second support bar 134. The first support bar cutout 162 and a second support bar cutout 164 preferably include a plurality of cutout touch-offs 166 providing the cutouts with added stability. The cutout touch-offs 166 project upwardly from the cutouts to the shelf top surface 140 and are preferably rigidly melted or welded to the shelf top surface 140. However, it is also contemplated that the cutout touch-offs 166 come into contact with the shelf top surface 140 without melting or welding to the shelf top surface 140.
The shelf bottom surface 142 further preferably includes at least one strengthening recess 168. The at least one strengthening recess 168 preferably spans a distance slightly less than the distance between the first support bar cutout 162 and the second support bar cutout 164. The at least one strengthening recess 168 projects upwardly from the shelf bottom surface 142 and are preferably rigidly melted or welded to the shelf top surface 140. However, it is also contemplated that the at least one strengthening recess 168 comes into contact with the shelf top surface 140 without melting or welding to the shelf top surface 140.
The shelf bottom surface 142 further includes a plurality of shelf touch-offs 170 preferably located around the perimeter of the shelf 14. The shelf touch-offs 170 are generally formed in the shelf 14 during the manufacturing process and add further stability and support to the shelf 14. The shelf touch-offs 170 project upwardly from the shelf bottom surface 142 towards the shelf top surface 140 and are preferably rigidly melted or welded to the shelf top surface 140. However, it is also contemplated that the shelf touch-offs 170 come into contact with the shelf top surface 140 without melting or welding to the shelf top surface 140.
The secondary shelf 16 has substantially the same structure as the shelf 14. The secondary shelf 16 includes a first leg aperture 152, a second leg aperture 154, a third leg aperture 156, a fourth leg aperture 158, and a shelf orifice 160. The leg apertures on the secondary shelf are larger than the stop portions 112. The bottom surface 142 on the secondary shelf 16 also includes a first support bar cutout 162, a second support bar cutout 164, at least one strengthening recess 168, and a plurality of shelf touch-offs 170. Because the shelf 14 and the secondary shelf 16 include substantially the same features, the shelf 14 and the secondary shelf 16 can be interchangeable.
The shelf 14 and secondary shelf 16 are preferably blow molded thermoplastic, such as polyethylene. However, the shelf 14 and secondary shelf 16 could alternatively be manufactured using injection molding, rotational molding, or other methods of thermoplastic forming. In one embodiment of the present invention the shelf 14 and secondary shelf 16 could be constructed of materials such as metal, wood, or wood products.
The customizable skirt 26 is depicted in
To initially assemble the collapsible table 10, the secondary shelf 16 is placed onto the legs. At this point, the stop portions 112 are not yet connected to the legs. Also, at this point, the first leg 18 is not connected to the fourth leg 24 with the first brace member 136 and the second leg 20 is not connected to the third leg 22 with the second brace member 138. The first leg 18 slides into the first leg aperture 152 of the secondary shelf 16. The second leg 20 slides into the second leg aperture 154 of the secondary shelf 16. The third leg 22 slides into the third leg aperture 156 of the secondary shelf 16. The fourth leg 24 slides into the fourth leg aperture 158 of the secondary shelf 16. The secondary shelf 16 slides down the legs over the top portions 108 and the bottom portions 110 until the secondary shelf 16 lands onto the first support bar 132 and the second support bar 134. When the secondary shelf 16 is resting on the support bars, the first support bar 132 slidably fits into the first support bar cutout 162 of the secondary shelf 16 and the second support bar 134 slidably fits into the second support bar cutout 164 of the secondary shelf 16. Preferably the support bars are substantially the same size as the support bar cutouts and the support bars and support bar cutouts frictionally fit together.
After the secondary shelf 16 has been placed onto the legs and the secondary shelf 16 is resting on the support bars, the first half 128 and second half 130 of the stop portions 112 are connected to the legs. The stop portions 112 are preferably constructed of injection-molded thermoplastic and are connected to the legs with screws. The stop portions 112 could also be connected to the legs using a number of different methods, including but not limited to screws, bolts, rivets, or other suitable connecting means. As can be seen in
Next, the shelf 14 is placed onto the legs. The first leg 18 slides into the first leg aperture 152 of the shelf 14. The second leg 20 slides into the second leg aperture 154 of the shelf 14. The third leg 22 slides into the third leg aperture 156 of the shelf 14. The fourth leg 24 slides into the fourth leg aperture 158 of the shelf 14. The shelf 14 slides down the legs until the shelf 14 lands onto the stop portions 112. Because the shelf apertures are slightly smaller in size than the stop portions 112, the stop portions 112 hold the shelf 14 vertically in position.
The first leg 18 and the fourth leg 24 are then rigidly connected with the first brace member 136. The first brace member 136 is preferably connected to the first leg 18 and the fourth leg 24 using weldaments. The second leg 20 and the third leg 22 are rigidly connected with the second brace member 138. The second brace member 138 is preferably connected to the second leg 20 and the third leg 22 using weldaments. Finally, the legs and brace members are rigidly connected to the tabletop. The first brace member 136 is connected to the first channel 60 using bolts or screws. The second brace member 138 is rigidly connected to the second channel 62 using bolts or screws.
Once the collapsible table 10 is assembled, it can be used in an upright use position for using the collapsible table 10 or collapsed into a nested position for easy storage or transport. To collapse the table 10 into the nested position, the skirt 26 is removed from the skirt flange 46. Next, the table 10 is arranged so that the working surface 30 is facing downward or on the ground. The shelf 14, with the aid of gravity and the user, will fall downward and pass slide over the leg top portions 108 so that the top surface 140 of the shelf 14 lies adjacent to the tabletop underside 40. As the shelf 14 falls downward, it remains substantially parallel to the tabletop 12.
Next, the secondary shelf 16, with the aid of gravity and the user, will fall so that the top surface 140 of the secondary shelf 16 slides over the legs bottom portions 110, the stop portions 112, the top portions 108, and the top surface 140 of the secondary shelf 16 will come into contact with the bottom surface 142 of the shelf 14. As the secondary shelf 16 falls downward, it remains substantially parallel to the tabletop 12.
After that, the two legs with the shorter top portions 108, the first leg 18 and second leg 20 as depicted in the figures, are folded from the extended portion to a folded position such that the top portion 108 is substantially perpendicular to the bottom portion 110. The legs will hold the shelf 14 and secondary shelf 16 into a nested position. Finally, the two legs with longer top portions 108, the third leg 22 and the fourth leg 24 as depicted in the figures, are folded from the extended position to a folded position such that the top portion 108 is substantially perpendicular to the bottom portion 110. The third leg 22 and fourth leg 24 being folded from an extended position to a folded position can be seen in
To reverse the procedure and set the collapsible table 10 up into its use position, the third leg 22 and the fourth leg 24 are unfolded from a folded position to an extended position. Then the first leg 18 and second leg 20 are unfolded from their folded position to an extended position. The table 10 is then flipped over so that the feet 120 on the first leg 18, second leg 20, third leg 22, and fourth leg 24 are on the ground.
The secondary shelf 16 will slide down the legs over the top portions 108 and the bottom portions 110 until the secondary shelf 16 lands onto the first support bar 132 and the second support bar 134. When the secondary shelf 16 is resting on the first support bar 132 and second support bar 134, the first support bar 132 slidably fits into the first support bar cutout 162 of the secondary shelf 16 and the second support bar 134 slidably fits into the second support bar cutout 164 of the secondary shelf 16. Because the support bars are substantially the same size as the support bar cutouts, the support bars and support bars frictionally fit together.
Next, the shelf 14 slides down the legs over the top portions 108 until the shelf 14 lands onto the stop portions 112. Because the leg apertures on the shelf 14 are slightly smaller in size than the stop portions 112, the shelf is wedged onto the stop portions 112 and the stop portions 112 preclude the shelf 14 past the stop portions 112. When in the use position, the shelf 14 and the secondary shelf 16 provide the table with stability and lock the foldable legs into place. Finally, the customizable skirt 26 may be attached to the skirt flange 46 with Velcro®.
Although the table 10 according to the present invention is depicted and described comprising four legs, it is contemplated that the table could be constructed with as few as two legs. For example, the table could be constructed of two, three, five, or any other number of legs and still embody the inventive features of the present invention.
