Motorized extendable table

Abstract

A motorized extendable table having a tabletop assembly, first and second extension assemblies, a frame assembly, first and second extension frame assemblies, a motor housing, a computer assembly, a motor assembly, and a base assembly. In operation, the motor assembly moves the extension frame assemblies from a retracted to an extended configuration. Before reaching a fully extended configuration, the extension assemblies are raised to a same plane as that of the tabletop assembly. To go from the extended to the retracted configuration, the motor assembly moves the system in an opposite direction, moving the extension frame assemblies down and back onto a lower plane. Extension frame assemblies continue moving back until the fully retracted configuration is reached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(12) Referring now to the drawings, the present invention is generally referred to with numeral 10. It can be observed that it basically includes tabletop assembly 20, extension assemblies 40, frame assembly 70, extension frame assemblies 100, motor housing 160, computer assembly 180, motor assembly 200, and base assembly 250.

(13) As seen in FIGS. 1, 2, and 3, tabletop assembly 20 comprises tabletop 22 with tabletop ends 24 and 26. Tabletop 22 further comprises tabletop edges 28 and 30.

(14) Extension assemblies 40 comprise extension top faces 42 having respective extension ends 44 and extension distal ends 46. In a retracted configuration, extension assemblies 40 are disposed under tabletop assembly 20. In an extended configuration, extension assemblies 40 are disposed on a same plane as that of tabletop assembly 20, in a way that extension ends 44 abut tabletop ends 24 and 26, respectively. Base assembly 250 is mounted to frame assembly 70. Base assembly 250 comprises legs 252. Frame assembly 70 is fixedly mounted under tabletop assembly 20.

(15) As seen in FIG. 3, extension frame assembly 100 comprises extension bars 106. Extension bars 106 are hingedly mounted to lateral frame members 102 with double pivoting hinges 108. Extension assemblies 40 are fixed on respective extension frame assemblies 100.

(16) As seen in FIGS. 3 and 4, in operation, belt 214 moves connectors 216, best seen in FIG. 5, causing extension rods 228 and 234 to move respective extension frame assemblies 100 from the retracted configuration to the extended configuration. At a predetermined distance before reaching the fully extended configuration, stoppers 79, stop extension bar stoppers 114 and therefore extension bars 106, while lateral frame members 102 continue moving. The movement of lateral frame members 102 cause a rotation of double pivoting hinges 108, urging extension bars 106 to raise/elevate, positioning extension top faces 42 at the same plane as that of tabletop assembly 20. The fully extended configuration is reached when switch actuator 226 actuates switch 224 to stop motor assembly 200. To go from the extended to the retracted configuration, motor assembly 200 is activated to move belt 214 in an opposite direction with respect to the direction described above. Thus, belt 214 moves connectors 216, best seen in FIG. 5, causing extension rods 228 and 234 to move extension frame assemblies 100 from the extended to the retracted configuration. At a predetermined distance, lateral frame members 102 go back. A weight of extension assemblies 40 makes double pivoting hinges 108 rotate back and extension bars 106 move downwardly, thus positioning extension top faces 42 to a lower plane. Extension frame assemblies 100 continue moving back until achieving the fully retracted configuration, reached when switch actuator 226 actuates switch 222 to stop motor assembly 200.

(17) As seen in FIG. 4, bridges 110 are mounted transversally to extension frame assemblies 100. Bridges 110 have bridge ends 112. Specifically, bridge ends 112 connect extension bar proximal ends 107 of extension bars 106 with extension bar stoppers 114.

(18) As seen in FIGS. 4 and 5, frame assembly 70 comprises longitudinal rails 72 and 74 and transversal frame members 78. Transversal frame members 78 are leveled with a bottom wall of longitudinal rails 72 and 74 in a way that ends of longitudinal rails 72 and 74 are free to receive extension frame assemblies 100. Transversal frame members 78 have stoppers 79, as shown in FIG. 3, at their ends. Ballbearing side slides 76 are mounted within each end of longitudinal rails 72 and 74.

(19) Extension rod 228 has proximal end 230 and distal end 232. Extension rod 234 has proximal end 236 and distal end 238. Proximal end 230 of extension rod 228 is fixed to the first connector 216, and distal end 232 is fixed to a first transversal frame member 104. Proximal end 236 of extension rod 234 is fixed to a second connector 216 and distal end 238 is fixed to a second transversal frame member 104.

Computer assembly 180 comprises remote control 260 seen in FIG. 10.

(21) Motor assembly 200 comprises motor 202 with sprocket 204 and chain 206 mounted thereto. Supporting blocks 208 hold sprocket 210 to which chain 206 is mounted too. Motor assembly 200 further comprises pulleys 212 and 220. Belt 214 is mounted to pulleys 212 and 220. Pulley 212 is connected to sprocket 210 with a shaft (not seen). Belt 214 has connectors 216. A first connector 216 is fixed to a lower portion of belt 214, while a second connector 216 is fixed to an upper portion of belt 214 at an opposite position with respect to the first connector 216. Motor assembly 200 further comprises connector 218, which moves switch actuators 226 between two extreme positions of connectors 216. Switches 222 and 224 are cooperatively disposed next to pulleys 212 and 220, respectively. Extension rods 228 and 234 extend from first and second connectors 216, respectively.

(22) As seen in FIGS. 5 and 6, each extension frame assembly 100 comprises lateral frame members 102 and transversal frame members 104. Lateral frame members 102 have respective lateral frame member proximal ends 103. Lateral frame member proximal ends 103 are mounted to ballbearing side slides 76 and therefore within longitudinal rail 72, seen in FIG. 4, and longitudinal rail 74.
