- members 100 and 102 have telescoping tubular sleeve portions 110 and 112, and inside of these sleeves is a coil spring 114, which urges the members 100, 102 apart.
- Annular shoulders 116 and 118 on members 100, 102 bear against the inside of tubing 64 around the margins of holes 108, to limit the outward movement of members 100 and 102.
- the spherically rounded outer ends 104 of members 100 and 102 are pressed inwardly between the thumb and a finger of one hand, and this unseats the cylindrical portions 106 from their holes 108. With the members 100, 102 pressed inwardly far enough, the tubing 64 can be turned on post 66, carrying with it the tabletop l8.
- a handle 120 is provided on the edge of tabletop 18 closest to the front of the chair when the table is stowed away under the chair.
- the mode of operation of the invention is as follows: Assuming that the table is stowed away underneath the chair 12, the first step is to pull the tabletop out to the position shown in FIG. 2, which is accomplished by grasping handle 120 and pulling outwardly on it. This causes carriage 32 to slide outwardly along tracks 20, 22 until the carriage reaches the forward end of its travel. At this point, the free end of tabletop 18 is grasped with one hand and raised up to the position shown in FIG. 3. As the post 16 reaches the vertical position, pin 56 drops into notches 60 in tubular To swing the tabletop around from the phantom line position of FIG.
- the tabletop 18 can be moved toward or away from the person seated in chair 12, by merely pushing the tabletop outwardly to the limit of travel of sliding carriage 32, or pulling it back toward the front side of chair 12 until the post 16 contacts the chair. If desired, the tabletop 18 can be released and swung around to a position at 90 from the position shown in solid lines in FIG. 1, which will place the end of the tabletop back against the body of the person seated in the chair. This enables the user to eat off the tabletop without having to sit forwardly on the chair, as the edge of the tabletop can be brought as close to the users body as he wishes.
- the tabletop 18 is first swung around to the phantom line position of FIG. 1, after which the bottom end of post 16 is grasped in one hand and pulled outwardly against the pressure of spring 54. This unseats pin 56 from notche 60, and allows the post 16 to be laid down to the horizontal position of FIG. 2. The tabletop is then pushed rearwardly, causing the carriage 32 to slide rearwardly on tracks 20, 22. When the tabletop is all the way back, it is virtually completely concealed and practically out of sight.
- While the invention is perhaps best suited for use in eating meals or snacks while watching television, it is also of equal use as a party" table, as in the case of a buffet dinner. Also, drinks and horsd'oeuvres, nuts and other finger foods may be held on the table while playing various card games or otherwise engaging in party activities. Still another use for the stow-away table of the invention is for bed-ridden patients, in which case the frame structure 14 would be mounted on the underside of the bed, and would be pulled out to one side thereof.
- a stow-away table for use with a chair or other piece of furniture comprising:
- a supporting frame structure mounted on the underside of said chair, said structure including a pair of laterally spaced, parallel tracks extending from front to rear with respect to said chair;
- carriage means mounted on said tracks for sliding movement with respect thereto between a retracted position and an extended position;

DESCRIPTION OF THE PREFERRED EMBODIMENT:
In the drawings, the table of the present invention is designated in its entirety by the reference numeral 10, and in FIGS. 1, 2 and 3, the table is shown as it appears mounted on an overstuffed living room chair 12, of the type in which television is commonly viewed. The table 10 is supported on a structural framework 14 which is attached to the underside of the chair, and extending upwardly along the front side of the chair is a vertical post 16, which supports the tabletop 18 at its top end.
As best shown in FIG. 4, the structural framework 14 consists of two laterally spaced, parallel side members 20 and 22 which, as shown in FIG. 13, are in the form of deep channel members having sharp internal corners, and smoothly finished inner surfaces. The side members 20 and 22 are cross-connected at their back and front ends by transverse members 24 and 26. Ad justably connected to the rear ends of members 20, 22 are extension angle irons 28, having screw holes 30 in their horizontal top flanges. Extension members 28 can be adjusted to increase or decrease the overall length of the frame side members, so as to locate the screw holes 30 directly under a frame cross member at the back of the chair 12. Other screw holes 30 are provided in the ends of front cross members 26, and attachment screws (not shown) are passed through these holes and screwed into the wooden frame members on the underside of the chair to solidly connect the framework 14 thereto.
Slidably mounted on the side members 20, 22 of framework 14 is a carriage 32, consisting of two parallel cross members 34 and 36, which are connected at their ends to longitudinally extending, solid rectangular bars 38. The outer edges of bars 38 extend into the channels 20, 22 with a slight amount of clearance on all sides, and at opposite ends of each member 38 there are three cylindrical cavities 40 (see FIG. 13) formed in the top, bottom, and outer edge of the bar, within which are contained ball bearings 42. These ball bearings bear against the inside surfaces of the channel 22 on the sides and bottom thereof, and provide friction-free linear movement of the carriage within the members 20, 22.
Fixed to the top side of the carriage 32 on one side thereof is a rectangular plate 44, and attached to its underside is a foreand-aft extending angle iron 46. Bearing against the vertical flange of angle iron 46 and against the under side of rectangular plate 44 is a tubular member 48, which is solidly attached to the members 44 and 46. Extending through the tubular member 48 and slidable and rotatable therein is another tubular member 50, which projects beyond both ends of member 48. The rearwardly projecting end of tubular member 50 has an annular collar 52 fixedly attached thereto, and confined between the collar 52 and the back end of tubular member 48 is a compression coil spring 54, which exerts a rearward thrust against collar S2, uring the tubular member 50 to the rear. Rearward movement of the tubular member 50 is limited by a diametrically extending pin 56, which passes through member 50 on the front side of tubular member 48. Pin 56 bears against the front end of tubular member 48 and its ends seat against annular shoulders 58 on opposite sides of member 50, each of said shoulders 58 being slightly more than 90 in angular distance, so that the pin 56 and member 50 can turn 90. At one end of each of the shoulders 58 in a recess 60, into which the pin 56 drops when the post 16 is in the upright position, thereby locking the post in the vertical position.
Fixed to the top end of the tubular post extension member 64 is a crosspiece 78, which lies just beyond and slightly below the end of tabletop 18. Tabletop 18 has two lengthwise-extending, tapered strips 80 attached to its underside, and these project slightly beyond the end of the tabletop and pass on either end of the crosspiece 78. The ends of the members 80 are pivotally connected to crosspiece 78 by means of a pin or rod 82, which extends through member 78 and turns freely therein. By virtue of this construction, tabletop 18 is hinged for vertical swinging movement to the top end of post 16,64.
The tabletop 18 is braced vertically to support any load placed thereon by means of two brace members 84, which are connected together intermediate their ends by a cross strap 86. The brace members 84 converge, and their ends pass on opposite sides of tubular member 64, where they are connected together by a transverse pin extending diametrically through member 64 and through aligned holes in the ends of members 84. A handle 88 is fixedly attached to one of the braces 84, as shown in FIG. 7, the purpose of which will be explained presently.
At their other ends, members 84 have laterally projecting pins 90, which slide freely along longitudinally extending slots 92 formed in members 80. At the end of each slot 92 nearest the post 64 is an upwardly extending notch 93 (see FIG. 14) in which the pins 90 seat to lock the tabletop 18 in horizontal position. The pins are lifted up into seat 93 by means of a spring wire 94, which is anchored at one end by a clamp 96 to the side of member 80. Fastener 96 is located a short distance beyond the end of slit 92, and wire 94 extends in an arcuate curve from the top of the fastener to the bottom edge of the slot, crossing the slot at an acute angle and passing under the notch 93.
As pin 90 approaches the end of slot 92 due to rais- I ing the tabletop 18 to the horizontal position, pins 90 cams the wire 94 downwardly, and then as the pin reaches the extreme end .of the slot 92 directly below notch 93, the upward pressure of spring wire 94 lifts the pin into the notch and holds it there. To unseat the pin 90 from notch 93, the outer end of handle is raised slightly, and this causes its attached brace 84 to pivot downwardly and thereby pull the pin down out of notch 93 against the pressure of spring wire 94. The tabletop 18 can then be lowered to the position shown in FIG. 3.
To release .the tabletop so that it can be swungaround from one position to another, the spherically rounded outer ends 104 of members 100 and 102 are pressed inwardly between the thumb and a finger of one hand, and this unseats the cylindrical portions 106 from their holes 108. With the members 100, 102 pressed inwardly far enough, the tubing 64 can be turned on post 66, carrying with it the tabletop l8.
When the tubing 64 has completed a degree turn,
the spring-loaded members 100, 102 drop into the holes 108 again, locking the tabletop in its new posi- IIOII.
To facilitate pulling the carriage l4 and tabletop l8 outwardly from under the chair 12, a handle 120 is provided on the edge of tabletop 18 closest to the front of the chair when the table is stowed away under the chair.
The mode of operation of the invention is as follows: Assuming that the table is stowed away underneath the chair 12, the first step is to pull the tabletop out to the position shown in FIG. 2, which is accomplished by grasping handle 120 and pulling outwardly on it. This causes carriage 32 to slide outwardly along tracks 20, 22 until the carriage reaches the forward end of its travel. At this point, the free end of tabletop 18 is grasped with one hand and raised up to the position shown in FIG. 3. As the post 16 reaches the vertical position, pin 56 drops into notches 60 in tubular To swing the tabletop around from the phantom line position of FIG. 1, to that shown in solid lines, the spherically rounded ends 104 of members 100, 102 are pressed inwardly by the finger and thumb of one hand, releasing the lock and allowing the tabletop and tubing 64 to swing around 180 degrees to the position shown in solid lines. The tabletop is now in position for use. If it is desired to raise the tabletop to a little higher position, set screw 70 is released by backing off the knurled head 75, and this allows the upper tubing portion 64 and post 66 to be raised up from the end. of tubular post 16. When the tabletop has been elevated to the desired position, set screw 70 is again tightened.
The tabletop 18 can be moved toward or away from the person seated in chair 12, by merely pushing the tabletop outwardly to the limit of travel of sliding carriage 32, or pulling it back toward the front side of chair 12 until the post 16 contacts the chair. If desired, the tabletop 18 can be released and swung around to a position at 90 from the position shown in solid lines in FIG. 1, which will place the end of the tabletop back against the body of the person seated in the chair. This enables the user to eat off the tabletop without having to sit forwardly on the chair, as the edge of the tabletop can be brought as close to the users body as he wishes.
To stow the table away after use, the tabletop 18 is first swung around to the phantom line position of FIG. 1, after which the bottom end of post 16 is grasped in one hand and pulled outwardly against the pressure of spring 54. This unseats pin 56 from notche 60, and allows the post 16 to be laid down to the horizontal position of FIG. 2. The tabletop is then pushed rearwardly, causing the carriage 32 to slide rearwardly on tracks 20, 22. When the tabletop is all the way back, it is virtually completely concealed and practically out of sight.
While the invention is perhaps best suited for use in eating meals or snacks while watching television, it is also of equal use as a party" table, as in the case of a buffet dinner. Also, drinks and horsd'oeuvres, nuts and other finger foods may be held on the table while playing various card games or otherwise engaging in party activities. Still another use for the stow-away table of the invention is for bed-ridden patients, in which case the frame structure 14 would be mounted on the underside of the bed, and would be pulled out to one side thereof.
While I have shown and described in considerable detail what I believe to be the preferred form of my invention, it will be understood by those skilled in the art that the invention is not limited to such details, but i might take various other forms.
