Foldable table attachment for a collapsible chair
BACKGROUND OF THE INVENTION 
     The present invention is directed generally toward a foldable table attachment for a collapsible chair and more particularly to such a table attachment for a chaise lounge of the type having front and back panels pivotally connected to opposite ends of a seat portion and legs pivotally foldable against the underside of the seat portion. 
     Collapsible chairs, also known as chaise lounges, have been in existence for a long time and are well known in the art. The chairs are commonly used by sunbathers at the beach or in the backyard and may be found in one form or another in almost every home. 
     One disadvantage of presently available collapsible chaise lounges of the type described is the lack of any available sturdy surface on which to place drink glasses, books and the like. The usual solution is to set such articles on the ground or to provide a self standing table in addition to the chair. The requirement of the self standing table defeats one of the principle advantages of the collapsible table, saving space, since most self standing tables cannot be folded flat. Accordingly, a primary objective of the present invention is to provide a table attachment which may be folded flat within the collapsed chair to facilitate transportability. Additionally, most self standing tables are not designed specifically to be used with collapsible chairs and as a result are too high relative to the chair. Consequently, it is an additional objective of the present invention to provide a table attachment of a height for comfortable use with a collapsible chaise lounge of the type described. 
     Additionally, it is an objective of the present invention to provide a table attachment which is sturdy but which may be folded into the chair thereby requiring no additional storage space. 
     Another disadvantage of presently available collapsible lawn furniture is that since the table is a separate piece of furniture, a separate effort must be made to remember to bring the table, increasing the chances that it will be forgotten and left at home. Also, the table may not be readily available, thereby requiring a search for its location and the resulting frustration accompanying such a search. Therefore, it is an additional objective of the present invention to provide a table attachment which is securely connected to the chair thereby eliminating the need to remember and locate the table prior to a recreational outing. 
     It is an additional objective of the present invention to provide a foldable table which is lightweight, simple and rugged in construction, inexpensive to manufacture and efficient in operation. 
     U.S. Pat. No. 4,553,785 discloses a cover for lounge chairs including a separate table accessory connectable by down turned tabs insertable through slits in the cover for engaging a side bar of the chair seat. The patented device lacks several features and advantages of the present invention, such as the present invention&#39;s secure and relatively permanent connection of the table attachment to the chair side bar resulting in rigidity and stability and negation of the possibility of losing or forgetting the table. Additionally, the table of the present invention may be folded to lie flat on the surface of the chair for storage and transportation without the possibility of damaging the chair&#39;s fabric strips as might occur with the patented device. 
     SUMMARY OF THE INVENTION 
     The foldable table apparatus of the present invention includes a table surface pivotally connected on one end to the side bar of a collapsible chair and on the other end to a support member serving to maintain the table surface in a substantially parallel orientation relative to the ground surface. The pivotal connection of the table surface to the chair allows the table to be pivoted from the lowered use position, upward and over the chair such that the table will lie flat against the surface at the chair seat in the storage position. The table support member is attached so that the member may be folded flat against the underside of the chair seat. Therefore, the entire foldable table apparatus may be conveniently stored as an integral part of the collapsible chair, not occupying any more space than the chair alone. The table support member may also include rubber foot attachments at the ground contact point to reduce movement of the support member while contacting the ground in the lowered use position. 
     The method for deploying the folding table includes the steps of: providing the collapsible chair and folding table of the present invention; ensuring the back and leg sections of the collapsible chair are extended; extending the table support member away from the underside surface of the table; pivoting the table surface away from the chair seat in the storage position and around the chair side bar until the support member contacts the ground in the use position, and the leg-locking mechanism holds the leg firmly in the vertical position.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The foldable table attachment 10 of the present invention is illustrated in FIG. 1 in assembly relation with a chaise lounge 12. The chaise lounge includes a peripheral seat frame 14, as shown in FIG. 5, including opposite side bars 16 and a flexible seat portion 18 connected to and spanning the side bars for supporting a person seated thereon. Back and leg support panels 20 and 22 are pivotally connected to opposite ends of the seat frame so as to be collapsible in generally stacked relation on top of the seat frame 14 for storage and transport. A pair of folding leg structures 24 are pivotally connected to the seat frame for movement between downwardly and outwardly inclined support positions and storage positions engaged against the underside of the seat portion 18. The connection of the back and leg panels 20 and 22 to the seat portion 18 generally enables the panels to be supported at various selected angles relative to the seat portion. 
     Table attachment 10 includes a table top 26 having a top side 28 and underside 30. Table top 26 includes a generally U-shaped frame 32 having spaced apart legs 34 and 35 with outer ends connected to an outer cross member 36 and opposite free ends. A top panel 38 spans the legs 34, 35 for supporting articles thereon. The top panel 38 may be secured to the frame 32 by screws 40 or bolts, as indicated in FIG. 3, or by any other suitable means. One alternative would be to provide generally C-shaped down turned tabs on the underside of top panel 38 for snap fit engagement with the tubular members of U-shaped frame 32. 
     Pivotally connected to the table top frame 32 is a leg means 42, illustrated in the form of a U-shaped member having upper ends connected to the table frame 34/35, such as by the pivotal connectors 46, illustrated in FIG. 3. 
     Pivotal connector 46 includes a plastic or nylon bushing 48 seated within a side opening 50 in the table frame 32 and a pivot pin 52 rotatably received within the bushing and protruding therefrom a short distance toward the opposite leg. The upper ends 44 of the U-shaped leg means 42 each have an opening 54 on the inner and outer side thereof for receiving a respective pivot pin 52. The U-shaped leg means 42 has sufficient inherent flexibility that the upper ends 44 may be compressed together for alignment of the pivot pins with the frame bushings 44, whereupon the outward bias of the upper ends 44 of the leg retain the leg pivot pins in the frame bushings. In a preferred embodiment, the U-shaped leg means 42 would include a pair of resilient feet 43a and 43b wrapped around the lower section of the U-shaped leg means 42 and made of foam rubber or the like. The feet 43a and 43b act to reduce movement of the U-shaped leg means 42 on the ground. 
     Also preferred is that the U-shaped leg means 42 may be pivoted from its vertical support position to enable the height of the outer part of the table top 28 to be adjusted relative to the C-shaped brackets 56 described below and thus the leg mean 42 serves as a multiple position support member. The leg means 42 would be held in the desired position by frictional ground contact by the resilient feet 43a and 43b, thus preventing slippage. By pivoting the U-shaped leg means 42, the distance between the outer end of the table top 28 and the ground can be increased or diminished, thereby enabling the table tope 28 to remain substantially horizontal. 
     The pivotal connectors 53 (FIG. 4) for hingedly connecting the table top 26 to a seat frame side bar 16 includes a pair of generally C-shaped brackets 56, each having a central portion 58 pivotally wrapped around a side bar 16 and opposite free ends 60. The free ends 6 are preferably formed to conform to the outer periphery of the respective frame 34 or 35 so as to define a partial frame receiving sleeve. The free ends 60 have holes 62 adapted for registration with similar holes 64 in the frame 34/35 for receipt of a fasteners such as bolts 66 therethrough. A wing nut 68 secures the table frame 34/35 to the brackets 56 and onto the side bar 16 of chaise lounge 12. As seen in FIG. 4, the bent free ends of the brackets 56 are tapered as at 70 along an arcuate curve to resist axial movement of the table frame 34/35 toward the side bars 16 on which they are pivotally mounted. 
     The C-shaped brackets 56 enable pivotal movement of the table top 26 from a storage position in generally registered engagement overlying one surface of flexible seat portion 18 to a substantially horizontal use position extended transversely outwardly from the seat frame side bar 16, as illustrated in FIG. 1. Note that the C-shaped brackets 6 impose no limitation to pivotal movement on side bars 16 so the table 26 can be just as easily pivoted downwardly and upwardly against the underside of flexible seat portion 18, if desired. 
     In a preferred embodiment, the table top U-shaped frame 32 is formed of three quarter inch outside diameter zinc-coated round steel or aluminum tubing. Wall thickness may vary. Since that is a common material for the peripheral seat frame 14 of the type of chaise lounges illustrated herein, the table top 26 is generally positionable substantially within the horizontal extent of the peripheral seat frame 14 when pivoted to its storage position against the top or bottom surface of flexible seat portion 18. The flexibility of seat portion 18 accommodates pivotal movement of the table top to either of these storage positions. 
     The material of the table top leg means 42 in the preferred embodiment is a half inch outside diameter to 3/4 outside diameter whereas wall thickness may vary from 0.029 to 0.049. Since the leg pivot pins 52 intersect the centers of both the leg tubing 42 and table top frame 32, the leg means is easily pivoted to a storage position within the confines of the thickness of the table top frame 32. 
     As a result, it is seen that upon pivotal movement of the table top legs to the storage position with the table top and upon pivotal movement of the table top into a storage position within the peripheral seat frame 14 of the chaise lounge 12, the chaise lounge can be collapsed in the normal fashion for transporter storage without taking any more room than it otherwise would without the foldable table attachment 10 of the invention. The table attachment 10 thus adds no size or bulk to the collapsed chaise lounge, very little weight and substantial function since it enables the support of articles on a firm flat surface which is wholly lacking in a conventional chaise lounge. 
     Whereas the invention has been shown and described in connection with a preferred embodiment thereof, it is apparent that many modifications, substitutions and additions may be made which are within the intended broad scope of the appended claims. 
     Thus there has been shown and described a foldable table attachment for a collapsible chair, which attachment meets all of the stated objects.
