Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a jack operated foldable table comprising a table assembly and an optional seat assembly. 
       BACKGROUND OF THE INVENTION 
       [0002]    Foldable furniture is well known in the art specifically chairs and tables. Foldable tables present two essential benefits, they occupy little space during the storage and can accommodate several people in the unfolded operating state. There are many families which does not require large table surfaces on a daily basis. However from time to time they need to accommodate larger numbers of guests. For them having a foldable table and chairs is one solution. Further in the current real estate market with more and more people living in condominiums with small apartments, modular foldable furniture becomes desirable. 
         [0003]    There are number of collapsible tables and collapsible dining sets described in prior art. 
         [0004]    U.S. Pat. No. 6,065,802 discloses a folding table and a seating apparatus comprising a circular table and eight stools. This assembly, even in a folded state, occupies a large space and does not provide a sufficient solution to space limitations in condominiums. 
         [0005]    There are several “umbrella type” foldable tables as disclosed in U.S. Pat. No. 786,732; U.S. Pat. No. 2,162,298 and U.S. Pat. No. 5,425,315. These tables which occupy a small space are disadvantageous in that, when collapsed, the upper table surface folds outward and remains open to air subjected to dust and dirt. This is undesirable due to sanitary concerns. 
         [0006]    Further U.S. Pat. No. 4,144,823 discloses a collapsible table and a seat assembly in which the table top is stored inside the interior of the housing. The described design has a limitation in the size of the table which can be nested inside the interior. Further there some operational limitations: the folding and the unfolding of the table are complicated and physically challenging. Finally this type of assembly is adapted to be used mostly outdoors and is not suitable for the indoor use. 
         [0007]    There were numerous attempts to develop foldable tables with a seat assembly, however most of those tables had various deficiencies. Some expose the table tops to the environment making it a sanitary concerns. Others have a complicated mechanical structure while others occupied a lot of storage space. 
         [0008]    Another deficiency of the foldable tables described in the prior art was the folding and unfolding operation. All the tables had to be manually operated and therefore the procedure of folding and unfolding required physical strain and limited the manufacturing of tables to a smaller size. 
         [0009]    It is therefore a primary object of the invention to provide a foldable table operable by a jack to make the folding and unfolding of the table effortless. 
         [0010]    It is yet another object of the invention to provide a foldable table which does not expose its working surface to the environment during the storage in the folded state. 
         [0011]    It is another object of the invention to provide a foldable table with a lid which serves as a lid in the folded state and as a serving surface in the operational state. 
         [0012]    It is yet a further object of the invention to provide a foldable table with a foldable seat assembly operable by a jack. 
         [0013]    Thus the present invention relates to a foldable table and a seat assembly which overcomes the deficiencies of the prior art. The present invention is directed to an improved foldable table which is easy to store and easy to operate, the table is not limited in size and does not expose the table top to the environment during storage. 
         [0014]    Further and other objects of the invention will become apparent to those skilled in the art when considering the following summery of the invention and the more detailed description of the preferred embodiments illustrated herein. 
       SUMMARY OF THE INVENTION 
       [0015]    According to the present invention, an improved foldable table that opens and folds into the table base by a hydraulic jack is provided. 
         [0016]    The folding table assembly comprises a table base, a foldable table top and a jack assembly which folds the table top into the table base for storage purposes and pushes out the table top from the table base for its operative state. The folding table assembly further comprises a lid which is placed on the rim of the table base when the foldable table top is folded and is used as a table top of the small column table. When the table top is unfolded, this lid turns into a “Lazy Susan” in the centre of the table. 
         [0017]    The table base comprises a bottom and a hollow pillar opening at the top. This table base houses a jack assembly attached to the bottom and contains the foldable table top in the folded position. The table base further supports the foldable table top in its unfolded position. 
         [0018]    The term “jack” used through this application for clarity, refers to any lifting/lowering device known to the person skilled in the art and includes: mechanical, electrical, hydraulic, pneumatic and other lifting/lowering devices. 
         [0019]    The jack assembly may comprise a jack with extended lifting legs, these legs have sufficient extension range to push out the foldable table top from the interior of the table base. This assembly further comprises a telescopic stand attached to the bottom of the base and the jack and the bottom of a lifting portion of the foldable table top. This telescopic stand prevents radial movement of the table top during the lifting operation of the jack. The jack assembly further comprises an electrical circuit, comprising a power supply, a transformer and an operation input which can be locally or remotely controlled. 
         [0020]    During storage, the jack assembly and the foldable table top are contained inside the hollow table base, while the lid is placed on the rims of the table base. In order to unfold the table for its fully opened operating state, the user removes the lid, and initiates the jack with a local or remote controller. The jack assembly extends vertically, pushing the lifting portion upward. The lifting portion pushes the folding table top outward from the table base and as soon as the upper arms with the top table members are released from the table base, the members unfold outwardly providing a table surface which is substantially parallel to the ground and substantially perpendicular to the table base. The lower arms remains inside the limitations of the table base at all times preventing the over extension of the upper arms. Thus the upper arms are lying on the rims of the table base restrained by the lower arms. Finally, the user places the lid in the centre of the open table covering the perimeter of the table base with the lower arms and providing the central piece of the table. 
         [0021]    When the fully open table is not further necessary, it may be folded in the same manner. The user first removes the lid from the center of the table assembly, then operates the jack assembly which pulls the lifting portion downward, and pulls the lower and upper arms into the interior of the table base and consequently the foldable table top is stored in the interior of the table base. Finally the user covers the table base with the lid and may use this column as a coffee table or any other supporting or decorative furniture. 
         [0022]    An object of this invention is to provide a foldable table which is easy to operate, which does not require physical strength and can be operated with a push of a button. Further this table can be manufactured in sizes larger then the comparable folding tables and can also be used indoors. Such tables can be used in various locations such as condominiums, residential buildings, restaurants, cafés, hotels, hospitals, federal buildings and other public areas where there is a concern for space and sanitary issues are important.

         [0066]    The folding table assembly is best depicted in  FIG. 1  and  FIG. 4  and is illustrated in its fully opened position in  FIG. 1  and fully closed position in  FIG. 4 . The folding table assembly has three main units: a table top  1 , a table base  2  and a jack unit  13 . The table base  2  comprises a wall surrounding a hollow interior such as a hollow pillar  12  which accommodates the table top  1  in its fully folded position and which supports the table top  1  on a rim  19  in its fully opened position. The hollow pillar is located on the base  11  which serves as the bottom of the table. The table base may be manufactured from various types of materials such as wood, plastics, polymers and metals. Inside the hollow pillar  12  in the center of the base  11 , the jack unit  13  is located. The jack unit  13  is the main operational unit of the folding table assembly  10 . The jack unit  13  lifts the folding table top  1  from the interior of the table base during its operation phase and folds the folding table top  1  into the table base for storage. The jack  13  is an electrical  12  volt jack which may be operated by a local controller or by a remote control. These lifting jacks are well known in the prior art and are readily available on the market from different manufacturers. The jack unit  13  has all the electrical wiring and controllers necessary for the operation of the folding table. A transformer if needed is also located in the proximity of the jack  13  on the base  11  inside the hollow pillar  12  of the table base  2 . Since the original jacks offered on the market have a limited elevation a set of lifting legs  15  are attached to the jack  13  in order to increase its elevation range. The lifting legs  15  are attached to the original lifting legs of the jack and works in a similar scissor mode as the original legs of the jack, this way extending the elevation range of the jack to operate in the range of the folding table assembly. The jack unit  13  further comprises a telescopic stand  14  attached to the jack&#39;s lifting legs and also attached to the center of the lifting portion  20  which is the base to the table top  1 . Besides the  12  volt jacks readily available on the market, any other type of jack can be utilized for the same function. 
         [0067]    The table top  1  comprises a lifting portion  20  which has on its perimeter a plurality of joints  21  and from those joints there are lower arms extending away from the center of the plate. Those lower arms are terminating by the elbow joints which are attached to the upper arms  25  and the inner hinges  24 . The upper arms  25  further extend away from the center of the table top  1  and terminate at the hinge joints  26  attached to the outer hinge  27 . All the parts of table top  1  may be manufactured from various materials suitable for the purpose of the table. These materials may be plastics, polymers and metals preferably metals such as aluminum. As illustrated in  FIG. 1  in its fully extended and fully opened position the table top  1  is supported by the rim  19  of the hollow pillar  12  and the outer hinge  27  extending away from the hollow pillar  12 . In the fully closed position as illustrated in  FIG. 4  the lifting legs of the jack unit  13  are folded inward to the hollow pillar and pulling with them the lifting portion  20  which pulls the lower and upper arms into the interior of the hollow pillar as well. The top of the table base  2  is then covered with the lid  30 . 
         [0068]    Now referring to  FIG. 2 , the table base is illustrated in its extended position and the table base comprising the base board  11 , a hollow pillar  12  and a lid  30 . The lid  30  is designed to cover the interior of the hollow pillar  12  in the fully closed position. Further in the fully operational position the lid  30  covers the center of the table top  1 . In a preferred embodiment the lid  30  may be used as a “Lazy Susan” in the fully opened position. The lid  30  is equipped with socket  33  fitting with the rod  32  best seen in  FIG. 10 . The lid  30  can then freely rotate on the rod  32  in the fully operational position of the table assembly  10 . There are many known techniques for manufacturing a “Lazy Susan” lid which can be used for this assembly. However, for the simplicity, the lid  30  can also be stationary. 
         [0069]    Referring now to  FIG. 3  which illustrates the jack unit  13  in its fully extended position with the extended lifting legs  15  and a fully extended telescopic stand  14 . The jack unit  13  which was previously disclosed is an electric operated jack which may be of any type available on the market while its arms might be extended with the lifting legs  15 . The jack unit  13  may be operated manually by an actuator  18  or remotely by an actuator which is not shown in this figure while the receiver may be attached to the body of said jack, also not shown in this figure. The jack unit  13  has an electrical power cord extending outwardly from the table base  2  for the connection to the electricity grid. If required, a transformer can be placed inside the hollow pillar  12  of the table base  2 . The electric sockets are not shown in  FIG. 3  but its operation would be apparent to one skilled in the art. 
         [0070]    Referring now to  FIG. 4  the table is illustrated in its fully folded position while the pillar illustrated here is transparent only for ease of the view of the fully folded table. As illustrated in  FIG. 4 , the movement of the jack unit  13  downward pulls the table top assembly  1  into the hollow pillar  12  and then lid  30  covers the top of the hollow pillar by lying on the rim  19 . In order to unfold the table assembly into its fully operating position the lid  30  has to be removed from the top of the table base. The jack unit  13  is actuated by a remote or local control and pushes the lifting portion  20  upwards extending the table top outwardly from the hollow pillar  12  and then unfolding the table top above the table base. 
         [0071]    Referring now to  FIGS. 5 and 6  the outer and the inner hinges are illustrated. The outer and the inner hinges each comprise a thin, elongated plate attached to an upper arm with a screw  34  while this plate may move around the screw  34  in clockwise or counterclockwise way. The path of the motion is limited by a small pin  29 . As illustrated in  FIG. 5 , in the folding motion when the lower arm  22  pulls the screw  34  toward the interior of the table base the folding process of the inner hinge starts and the plate  24   a  rotates counterclockwise relatively to the screw  34  and with this motion the pin  29   a  forces the right side of plate  24   b  to rotate clockwise relatively to the screw  34   a  while the left part of the plate  24   b  rotates clockwise relatively to the screw  34   b  and the pin  29   b  causes the plate  24   c  to rotate counterclockwise relatively to the screw  34   b.  As a result all plates of the inner hinge folds in a fan like motion due to the movement of the jack downward into the table base. Similar folding motion occurs for the outer hinge  27  as illustrated in  FIG. 6 . 
         [0072]    The ends of the plates are perpendicular to the arms which they are connected to. The joint of the plates are bent in an angle relatively to the body of the plate. This angle is affected accordingly to the number of plates in the table top. The strategic position of pin  29  allows the plates to move only in one direction during the folding motion and in the opposite direction during the unfolding motion of the table top. Further, the outer hinge plates and the inner hinge plates include top plate supports. Those plate supports are supporting the top plate of the table top creating the upper surface of the table. The table top plate can be glued, screwed, welded or attached to the plate support in any manner known in the art. 
         [0073]    Referring now to  FIG. 7  the section of the lifting portion  20  is illustrated with the lower arms  22  attached to the upper arms  25  through the joints  23 . The lower arms  22  are attached to the perimeter of the lifting portion  20  with joints  21 . The joints  21  move up and down and can not move in any other direction. Therefore lower arms  22  can move only in two directions: folding toward the center of the lifting portions during the folding motion and extending outward from the lifting portion during the unfolding motion. The joints  23  have two motions: one motion is an upward and downward motion in the attachment of the joints  23  to the lower arms  22  and the second motion is the rotational motion in the point of attachment of the screws  32  to the upper arms  25 . The rotational motion is the motion of the inner hinge  24  which is illustrated in  FIG. 8 . The restricting pins  29  of the outer hinge may be located on the outer side of the outer hinge as well as in the inner side of the outer hinge as it is illustrated in  FIGS. 5 and 6 . 
         [0074]    Referring now to  FIG. 9  the table top  1  is illustrated in its fully opened position with the lifting portion  20  in the center with joints  21  connected to the perimeter of the plate attached to the lower arms  22  attached to the joints  23  which are further attached to the upper arms  25  and extending through the hinge joints  26  to the outer hinge  27 . It is also easy to see that the lower arm  22  has a first end  35  and the second end  36  while the upper arm  25  has a first end  37  and the second end  38 . Further the top plates  28  are attached to the outer hinge  27  and to the inner hinge  24  between the upper arms  25 . The top plates  28  may be manufactured from durable polymers, wood, fiber glass, glass, plastics or metal. Thin sheets of metal such as aluminum are preferable but durable polymers can be used as well. The top plates  28  are attached between the upper arms  25 , the inner hinge  24  and the outer hinge  27 . 
         [0075]    During the folding operation the top table plates  28  are folded toward each other during the folding operation of the jack unit  13  and contained inside the table base  2 . 
         [0076]      FIG. 10  further illustrates the fully opened folding table assembly with the lid  30  lying on the top of the rod  32  attached to the center of the lifting portion. In this embodiment the lid  30  may easily rotate on the rod  32  in the motion of the “Lazy Susan”. A “Lazy Susan” is a part of the table which may rotate and assist users around the table to transfer food and cutlery from one side of the table to another just by placing it on the surface of the “Lazy Susan” and rotating it toward the person requiring the item. The designs of the “Lazy Susan” are well known to one skilled in the art and may be manufactured in different ways with different locations of the rotational devices while the lid  30  may be manufactured in the simplest way without the rotational motion of the “Lazy Susan”. 
         [0077]      FIG. 11  illustrates another embodiment of the invention. In this embodiment the folding table assembly further comprises a foldable seat assembly  3  which is attached to the lifting portion  20  with a rib  41  and therefore moves together with the lifting portion by the operation of the jack unit  13 . The core of the seat assembly is made of a hip  43  and a leg  46  attached by a knee joint  45 . The leg  46  stands on the ground with its foot  47  and the user sits on the seat  50  which extends between the hips  43  located on the adjacent seat. The seat  50  is made of fabric which may be accumulated into a seat tube  44  or in the operational position this fabric is extended from the seat tube  44  and attached to the attachment part  49  of the adjacent hip of the adjacent seat assembly. The attachment of the seat fabric  50  to the attachment part  49  is made by the attachment member  48 . The members  48  and  49  are designed to be easily attached together and keep those attachments during the term of the usage of the seat assembly until the user decides to disassemble the seat assembly by detaching the parts  48  and  49 . The attachments  48  and  49  may be of any type of attachments known in the art such as loops and hooks or any other types of attachments. There has to be at least one loop and hook device while in the preferred embodiment there are more loops and hooks  48  and  49  to attach the fabric of seat  50  between the hip of the adjacent seat assembly. The fabric of seat  50  may be made of any fabric available on the market stong enough to support the weight of a person. It can be made of polyester, polymer, strong fabric material or synthetic, rubberized, perforated for ventilation or made of any other seat material suitable for this utility. The hip  43  is attached to the rib  41  with the hip joint  42  which can slide through the sliding slot  51  of the table base  2 . 
         [0078]    Referring now to  FIG. 12  there is a table base illustrated in relation to the second embodiment of the invention. It shows a profile  52  with a sliding slot  51  attached to the table base. This profile and the slot are attached to the table base  205 , with each seat assembly through the perimeter of the table base. The profile  52  is made of a strong material preferably metal and securely attached to the table base  2  specifically to the hollow pillar  12 . The cut out  51  provides the sliding slot for the hip joint cut through the profile  52  leaving top and bottom parts  53  of the profile  52  to maintain the rigidity of the table base. 
         [0079]    Referring now to  FIG. 13  for ease of understanding only one seat assembly is illustrated. But it is understood that there are several seat assemblies through the perimeter of the table base.  FIG. 13  illustrates the attachment of the folding seat assembly to the lifting portion  20  and it shows the location and position of the seat assembly during the storage phase of the folding table set. 
         [0080]      FIG. 14  illustrates the folding seat assembly in its unfolded position attached at one end to the lifting portion with a rib, hip joint and hip of the leg extending perpendicular to the hip  43  with the foot  47  resting on the ground. In order to prevent unwanted collapse of the seat assembly the knee joint  45  has a safety device the spring pin  55 . This safety feature is illustrated in  FIG. 15 . When the seat assembly is in its fully unfolded position the spring pin  55  prevents the leg  46  from folding toward the hip  43 . In order to fold the seat assembly into its storage position the spring pin  55  has to be pressed and then leg  46  can be bent toward the hip  43 . 
         [0081]    There are also several safety features in this folding table and seat assembly. The jack has an upper and lower limits in order to prevent over extension and destruction of the table. The construction and the parts of the table are very rigid and simple. The folding seat assembly has its own safety features as illustrated on  FIG. 15 , this way the seat assembly can not collapse by itself under the weight of the user. 
         [0082]    In order to operate the first embodiment of the invention which includes only the folding table assembly the user has to remove the lid  30  and then press the button of a remote or local control of the table and wait until the jack unfolds the table top from the table base and then position the lid  30  in the middle of the table top. If the table top assembly is equipped with the rod  32 , the lid  30  has to be positioned on the rod  32  with the socket  33  and will be used as a “Lazy Susan” during the utilization of the unfolded table. In order to fold the table for storage, the lid  30  needs to be removed from its position and the operating button of the jack pressed again. Then the user needs to wait until the jack unit  13  folds the table top into the perimeter of the hollow pillar and then position the lid  30  on the top of rim  19  of the table base and store the table for the next usage. The covered pillar can be used as a night stand, as a coffee table or for any other decorative or utility usage. 
         [0083]    The second embodiment of the invention, the one that includes the foldable seat assembly requires more operation from the user. The first part for unfolding the table is the same as in the first embodiment, the user has to remove the lid  30 , press the button of the remote or local control of the jack unit  13 , wait until the table top unfolds from the interior of the hollow pillar, during the movement of the lifting portion the rib  42  pushing the hip joint  42  upward. By this motion the hip  43  is removed from its holding position inside the table base and move toward the position illustrated in  FIG. 14 . Then the user has to pull the leg portions  36  in order to lock spring pins  55  into the safety position to prevent the collapsing of the seating unit for every seat assembly around the table base. The user then has to pull the fabric of the seat  50  from the roller  44  located on the hips  43  of the seat assembly  3  and attach them to the attachment parts  48  and  49  of the proximate hips of the seat assembly. After the usage of the folding seat assembly and folding table the user has to disengage the attachment parts  48  and  49  of the seat  50  from the corresponding attachments parts on the proximate hips of each seat assembly, then the user has to disengage the spring pin  55  in order to fold the leg  46  of the seat assembly toward the hip  43 . Then the user has to press the button for operating the jack unit  13 , after removing the lid  30  from the top of the table. The jack unit  13  brings the table top into the interior of the table base and finally the user has to lock the leg portion of the seat assembly into the corresponding location around the perimeter of the table base finally placing the lid  30  on top of the table base on the rim  19 . 
         [0084]    Various improvements can be made to the folding table assembly. One of the improvements may be the attachment of small wheels onto the bottom of the table base, this will ease the movement of the table assembly from one part of the room to another for cleaning purposes. Another improvement may be a detachable electrical cord of the jack assembly which can be detached after the extension of the table and then removed and reattached in order to fold the table for storage. 
         [0085]    As many changes can be made to the preferred embodiments of the invention without departing from the scope thereof. It is intended that all matter contained herein be considered illustrative of the invention and not it a limiting sense.
