V. SUMMARY OF THE INVENTION
The present invention is a motorized extendable table, comprising a tabletop assembly, extension assemblies fixed on respective extension frame assemblies, a frame assembly fixedly mounted under the tabletop assembly, a motor housing, and a base assembly.
The motor housing houses a computer assembly and a motor assembly. The motor housing is mounted under the tabletop assembly within a space defined by the frame assembly. The computer assembly comprises a remote control. The base assembly comprises legs and is mounted onto the frame assembly.
The tabletop assembly comprises a tabletop with respective tabletop ends and tabletop edges. The extension assemblies comprise extension top faces having respective extension ends and extension distal ends.
The frame assembly comprises longitudinal rails, transversal frame members with respective stoppers, and ballbearing side slides. The ballbearing side slides are mounted within each end of respective longitudinal rails. The transversal frame members are leveled with a bottom wall of the longitudinal rails and the ends of the longitudinal rails receive the extension frame assemblies. Each of the extension frame assembly comprises lateral frame members having lateral frame member proximal ends, transversal frame members, and extension bars having extension bar proximal ends. The lateral frame member proximal ends are mounted onto respective ballbearing side slides within the longitudinal rails.
The extension bars have L- shaped defined by a bottom wall and a lateral wall. The lateral wall comprises double pivoting hinges. The extension bars are mounted onto an inner side of the lateral frame members, whereby the extension bars are hingedly mounted with the double pivoting hinges, and the lateral frame members are mounted onto the longitudinal rails.
The extension frame assemblies further comprise bridges transversally mounted, wherein the bridges comprise bridge ends that connect with respective extension bar proximal ends with extension bar stoppers.
The motor assembly comprises a motor, first and second sprockets, a chain, supporting blocks, first and second pulleys, and first and second switches. The first and second switches are disposed next to the first and second pulleys respectively.
The motor assembly further comprises a belt having first and second connectors, switch actuators, a third connector, and first and second extension rods having proximal ends and distal ends respectively. The chain is mounted onto the first and second sprocket. The supporting blocks hold the second sprocket. The belt is mounted onto the first and second pulleys and the first pulley is connected to the second sprocket.
The first connector is fixed to a lower portion of the belt, while a second connector is fixed to an upper portion of the belt at an opposite position with respect to the first connector. The third connector moves the switch actuators between two extreme positions of the first and second connectors.
The first and second extension rods extend from the first and second connectors respectively, whereby the proximal ends are fixed to respective first and second connectors, and the distal ends are fixed to respective transversal frame members.
The switch actuators actuate the first and second switches to stop the motor assembly to reach an extended configuration or a retracted configuration. In the retracted configuration, the extension assemblies are disposed under the tabletop assembly, and in the extended configuration, the extension assemblies are disposed on a same plane as said tabletop assembly.
It is therefore one of the main objects of the present invention to provide a motorized extendable table that can be operated and/or controlled with a remote control.
It is another object of this invention to provide a motorized extendable table that is volumetrically efficient for carrying, transporting, and storage.
It is another object of this invention to provide a motorized extendable table, which is of a durable and reliable construction. It is yet another object of this invention to provide such a device that is inexpensive to maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

VII. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
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.
As seen in figures 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.
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.
As seen in figure 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.
As seen in figures 3 and 4, in operation, belt 214 moves connectors 216, best seen in figure 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 figure 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.
As seen in figure 4, bridges 110 are mounted transversally to extension frame assemblies 100. Bridges 110 have bridge ends 1 12. Specifically, bridge ends 112 connect extension bar proximal ends 107 of extension bars 106 with extension bar stoppers 114.
As seen in figures 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 figure 3, at their ends. Ballbearing side slides 76 are mounted within each end of longitudinal rails 72 and 74.
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.
As seen in figure 5, motor housing 160 is mounted under tabletop assembly 20, seen in figure 1 , within a space defined by frame assembly 70. Motor housing 160 houses computer assembly 180 and motor assembly 200 therein. Computer assembly 180 controls and electronically operates motor assembly 200. Computer assembly 180 comprises remote control 260 seen in figure 10.
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.
As seen in figures 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 figure 4, and longitudinal rail 74.
As seen in figure 7, extension bars 106 have extension bar proximal ends 107. Extension bars 106 have L-shaped cross-sections defined by bottom wall 116 and lateral wall 118. Extension bars 106 have double pivoting hinges 108 mounted to lateral wall 118. As seen in figures 8 and 9, extension bars 106 are mounted to an inner side of lateral frame members 102. In turn, lateral frame members 102, are mounted to longitudinal rails 72 and 74, seen in figures 4.
As seen in figure 10, present invention 10 further comprises remote control 260. Remote control 260 actuates motor assembly 200, seen in figure 5, place present invention 10 in the extended configuration and retracted configurations.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
