Referring more in detail to the drawings:

I designates a combined food serving tray and reading rack constructed in accordance with the present invention and includes a table-like tray top 2, supporting leg members 3 and 4, and a reading rack 5 with holders therefor, The parts of the device are preferably formed of stainless material that may be readily kept in sanitary condition, such asstainless steel, aluminum, or combination of desired metal and wood, or a heat resistant plastic.

The table-like top 2 is formed from a single sheet of metal and has its top recessed as at 6 to prevent the containers of the food from sliding oii of the table or spilling onto the patient and bed. The top 2 has its sides turned downwardly forming a peripheralflange I, a substantial plane surface 8 being formed around the outer portion of the table top 2 The leg members 3 and 4 are preferably formed of a rod material of circular cross section, and each has a horizontal bar or rod portion 9 and diverging leg portions It and II joining therewith in laterally turned and rounded curved portions I2 and I3, the leg portions It and II being of suitable length to carry the tray-like top over thebody of a patient when the legs are supported on the bed of the patient.

In order that the device is adaptable for large persons the legs Hi and I I are preferably provided with extensions I4 preferably formed of tubular materialwhich. engage over the rod-like legs It: and II. The extensions are provided with elongated slots having a plurality of openings Iiiv of, slightly larger diameter than the slots. The rods ofthe legs I8 and II are provided with a plurality of sockets or recesses it adapted to receive a collar ll on the end of a pin I8 having a head I9. The pin 13' is provided with an enlarged portion or shoulder 26 of substantially the same size as the opening I6 in the extensions I 4 of the leg portions. A coil spring 21 is adapted to engage in the. opening I6 of the leg and resiliently-urgethe pin outwardly against the tubular extension, the collar I'i engaging against the in-- side of the extension to retain the same therein.

The recessed portion 6 of the top and the annularfiange I around the outside of the top form an annular or channel groove 22 underneath the table top and rigidly secured to the bottom side of the top in the annular groove or channel by screws or the like 23 arebrackets 24' having one end; rounded and forming bearings 25 for the horizontal members 9 of the legs I0 and II. I

have here illustrated four of the brackets, one at substantially each corner of the table and the free inner ends of the brackets at the rear of the table are welded to the lower inclined portion 26 of the recess portion of the table as indicated at 21, the brackets being so located that the outer edges will engage against the laterally curved portions of the legs to prevent lateral movement of the legs with respect to the table top.

Welded or otherwise rigidly secured longitudinally of the lower portion 28 of the bearing member 25 of the brackets are tubular members 29 having one end closed as indicated at 30 and the opposite end open and adapted to receive a plunger 3|. A coil spring 32 is provided to engage in the tubular members engaging against the closed ends 30 and against the end 33 of the plunger to provide spring tension on the plunger. The tubular members are provided with a slot 34 through which a threaded shank 35 extends. The shank engages in a threaded socket 36 in the plunger 3|, the shank having movement in the slot of the tubular member, the shank having an enlarged end forming a head 31. The plunger extends out of the end 3| of the tubular member a suflicient distance to engage against the laterally turned portion |2 of the leg members as indicated at 38 (Fig. 6) to retain the legs in table supporting position, and to lock the legs when in folded position.

Rack supporting members 39 and 4|! are mounted on each end of the plain surface 8 of the table for supporting the rack 5. To secure the brackets 24 and supporting members 39 and 49 to the table top 2 I provide screws 4| which extend through the brackets registering openings in the top of the table and extend through spacing sleeves 42 and engage in threaded sockets 43 in the supporting members 39 and 40 as best illustrated in Fig. 3. While I have here shown two screws for each bracket, any number may be utilized as desired. With this arrangement, it will be obvious that no heads of the screws or bolts appear on the top of the table. It will further be obvious that the supporting members 39 and 40 may be tubular and the screws engage in threaded openings therein. The ends of the members 39 and 40 are centrally bored and closed by rounded or tapered stops on the line as indicated at 44, Fig. 1.

The reading rack is formed of fiat sheet material to provide a back 45 having a plurality of openings 46 if desired to lighten the weight of the rack member. The lower edge of the rack is turned laterally as indicated at 41 and upwardly to form a flange 48 to form a trough-like member 49 for retaining books or other articles therein when the tray is in use, thus forming a holder for books or the like at the proper angle. Secured to the lower edge of the trough-like portion of the rack by welding or other suitable means are channel members 50 and having sides 52 and 53, the lower edges of which are bent inwardly to engage the rod supporting members 39 and 40 to retain the same slidably thereon.

It will be obvious that the rack is removable over the ends of the supporting members and to store the rack underneath the table when not in use, I provide a pair of brackets 54 and 55 adjacent the front legs of the table and secured over the brackets 25 by the screws 4| which hold brackets 25 to the table top. The brackets 54 and 55 have inwardly extending arms 56 and 51 provided with lateral extensions 58 and 59 turned slightly outwardly as indicated at 60 (Fig. 4) to 4 provide cam surfaces 6| for the reception of the side edges 62 and 63 of the rack.

When the device constructed as described is not in use the reading rack may be removed by sliding the channel members 59 and 5| over the ends of the supporting rod members 39 and 43 and stored underneath the table top by engaging the edges of the table in the brackets 54 and 55 just above described. The leg members 3 and 4 may be folded to lie flat against the bottom of the table by movement of the plunger 3| in the tubular member 29 through movement of the head 31 of the bolt 35 in the slot 34 of the tubular member, disengaging the end 38 of the plunger member from contact with the leg members.

When the device is to be used as a tray for serving food to the patient, the reading rack may be left in stored position and the leg members 3 and 4 moved to set-up or tray supporting position on movement of the plunger the same as when collapsing the leg members as the end of the plungers will also lock the leg members closed. If desired the dishes in which the food is served may be placed directly in the recess 6 of the table top or a serving tray may be received within the recessed portion, the side wall 64 of the recess preventing the dishes or tray from sliding therefrom and spilled food from getting on the patient or the bed.

When the device is to be used for reading or the like the rack 5 is readily withdrawn from the brackets by merely withdrawing the rack outwardly or outwardly and then sideways so that it clears the brackets 54 and 55. The channel members 50 and 5| are then slid over the ends of the supporting members 39 and 49 to any desired position at an angle to or from the patient.

If no longer legs are required, the leg extensions |4 may be moved downwardly on the rod ll! of the leg members by inward pressure on the head IQ of the pin l8 against the tension of the spring 2| to disengage the shoulder 20 from the opening IS in the sleeved extensions l4; and when the desired height of the leg is acquired, the spring 2| will cause the collar to again engage in the openings I6 to retain the legs in desired position.

If desired, non-skid members 56 such as rubber or the like may be engaged over the lower ends of the extension members l4 to prevent sliding of the device or tearing of the bed clothes.

It will be noted that the recessed bottom and surrounding ledge portion of the tray provide downwardly opening channels along two opposite sides of the recessed bottom and that the angle formed between the under face of the ledge portion and sides of the recessed bottom contain the rod portions of the leg members when they are journalled in the bearing members so that the lateral portions have bearing contact with the under side of the ledge portion when the leg members are in tray supporting position and that the opposite side of the lateral portions contact the sides of the recessed bottom portion when the leg members are in folded position. It is also obvious that the sliding plungers of the latches engage the sides opposite the contacting portions to retain the leg members substantially immovable in both positions thereof.

From the foregoing it is obvious that I have provided a combined tray and reading rack which is of simple and compact construction and well adapted to use of the patient, and when not in use may be conveniently stored. It is also obvious that the unit is composed of relatively few parts and folding of the leg members is conveniently and easily accomplished as well as removal of the rack for storage. This device can also be used for efiicient deluxe hotel room service, or private home use.

What I claim and desire to secure by Letters Patent is:

A tray having a bottom portion recessed below a surrounding ledge portion which ledge portion has a downwardly extending flange spaced outwardly from sides of said recessed bottom portion to form downwardly opening chanels along two opposite sides of said recessed bottom portion, leg members for supporting said tray and each having a horizontal rod portion contained within said downwardly opening channels and positioned within angles formed between under faces of said ledge portions and the sides of the recessed bottom, said leg members having lateral portions at ends thereof terminating in legs offset from the rod portions a distance substantially corresponding to the depth of the recessed bottom, bearings carried in said channels and journalling the ends of the hori zontal rod portions of the leg members for movement of the leg members from tray supporting position with said lateral portions in bearing contact with the under face of said ledge portion to a folded position with the lateral portions in contact with the sides of the recessed bottom portion and with the legs in substantially parallel contact with the under side of the recessed bottom portion, and a latch carried by a bearing 6 member for each leg member, said latches having sliding plungers supported in position by said bearing members for movement across under sides of the adjacent lateral portions to retain the lateral portions in said bearing contact with the under face of the ledge portion when the leg members are in tray supporting position and for movement of the plungers across opposite sides of the lateral portions to retain the lateral portions in said contact with the sides of the recessed bottom when the legs are in said folded position whereby the leg members are substantially immovable in said respective positions.
