Nov. 28, 1-950 J. M. ALLAN BED TABLE ADJUSTABLE VERTICALLY AND TILTABLY Filed Feb. 2, 1948 IIQVEN OR JOHN MUIR ALI-AN ATTORNEY Patented Nov. 28, 1950 BED TABLE ADJUSTABLE VERTICALLY AND TILTABLY John Muir Allan, Vancouver, British Columbia, Canada Application February 2, 1948, Serial No. 5,781 In Canada October 29, 1947 1 Claim. 1

My invention relates to improvements in bed tables Which are particularly adapted for hospitals for use by patients who are capable of using their arms and hands for light work.

The objects of the inVention are to provide a table having a base of substantial area and widely separated bearing points as to support its load with a minimum of movement and without interfering with the comfort of the patient; to provide a table top which is adjustable as to height and angle within a wide range of movement, and to provide such rigidity that a typewriter, draughting machine or other device can be suitably supported for appropriate use by the patient.

Referring to the drawings:

Figure 1 is a front elevational view of the invention with the table top tilted for use as a draughting board. 1

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a side elevational view with the table top set for receiving a service tray.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral I indicates generally a frame preferably of tubular construction. The frame is formed with side members 2 each substantially in the form of an inverted V to form a pair of inwardly inclined legs 4 and a cross piece 5 connecting said legs together. Each of the legs is provided with rounded rubber feet I to afford a grip upon the bed covering. The side frame members 2 are connected together with cross members 8 to hold them together as a unit.

Upon the legs 4 of the front of the frame, a pair of tubular slides II] are mounted, which are connected together with a horizontal bar [2 which serves to support a table top M. The table top is provided with fittings 15, each having a split tube clamp l6 which is rockingly mounted upon the horizontal bar I2 and is fitted with a screw H for the purpose of clamping the table in any desired position or angle on the bar. Each of the tubular slides is split at its upper ends as at [8 and is provided with a split clamp ring 19 having a clamping screw 20 by which to lock the slides to the legs.

With the table top set in the position as shown in Figure 3, a tray or other articles supported thereon, are so close to the body of a prone patient that he can reach them without effort and conveniently see what is put before him.

Should it be necessary for the table to be used to support a typewriter, the clamping screws 20 are slackened and the table top I4 is raised to appropriate height, raising the bar I2 and the tubular slides 10 as a unit along the legs, when the clamping screws are tightened to hold said slides in adjusted position. The clamping screws 5? are manipulated and the table top adjusted to a desired angle to support a typewriter, so that the patient may see his work and have his keyboard at a convenient height above the bed for comfortable typing. Since the slides ID are held in a position parallel to each other by the horizontal bar 12, they will move freely along the legs without binding, so that the top, even when loaded with a typewriter or other substantially heavy article, can be conveniently raised or lowered by the patient himself.

It will be noted that by rearwardly inclining the front legs of the device, the centre of gravity of a load on the table top will move inwardly between the legs as the table top is raised, thus ensuring the table against tipping when supporting a load such as a typewriter or the like.

What I claim as my invention is:

A bed table comprising a frame having a pair of side members each consisting of a length of material bent to form a pair of straight inwardly inclined front and rear legs connected at their upper end by a curved portion, a cross member united to the upper portion of the rear legs to form a rigid structure, a pair of tubular slides movable throughout the length of the front legs and a horizontal bar rigidly uniting the upper end of the slides together, said bar being adapted to support a table top.

JOHN MUIR ALLAN.
