TABLE FOR HOSPITAL EDS.

Application led February 18, 1928.

Anything resting on a patients lap soon be- Around hospitals a comes uncomfortable. common expedient 1s a table supported at one r side from a heavy base extending Aunder the bed and removable when not in use. Such a common construction takes up an unnecessary amount of space when not in use and is objectionable especially in modern hospitals `where space is at a premium either in the wards or in private rooms7 for the roomsare .generally small and with no space available for storage of bulky articles. Under this invention these disadvantages are overcome 'u and a comfortable table supportprovided which is capable vof being folded up out of the way when not in use.

According to this invention a tabl-e is .supported from the bed, is adjustable'in height,

longitudinal position, and angle of inclination7 yet adapted to be swung to a substantially upright position over the head of the bed when not wanted.

Referring to the drawings,

The bed 10 illustrated isof the usual hospital type although it will be understood Serialk No. 255,215.

that this invention may be applied to beds of other types. The table 11 is carried by the supporting yoke 12. A guide member 14 extends longitudinally along each side member 13 of the bed and is secured thereto at each end by clamps 15 fas shown in Fig. 3,. The ,clamps 15 are'prei'erably of a shape adapted to engage the side member 18 whether ofiron or Wood andwhatever shape it be. Mounted on each guide member 14 are clamps 16V and 19 heldin adjusted position by means of the tightening screws and wing nuts 18 and 2O respectively. These clampsglG and 19 are preferably permanently secured on 4the guide members 14 in the embodiment illustrated and the guide members 14 maybe mounted 'by means of the clamps 15,V although it Awill be understood that clamps 16'and 19 may be made removable and may be shaped to lit the bed side members13 so as to do away with Each end of the yoke 12 is secured to the ypivots 17 lon the clamps '16. 4Pivotally s e-` cured/tothe clamp 19 at 21 is a brace 22 also pivoted to the yoke at 23. longitudinal positionof the clamps 16 and 19 the table 11 and the yoke 1,2 maybe moved longitudinally of the bed to suit the patients needs. By adjusting the spacing between I By Aadj usting the the clamps 16 and'19 the height of the table j j 11 is controlled. Preferably a brace 22 is used on each side'lof th-e table although it will be seen that if desired abrace on only one side may be made suliiciently rigid.l

Vhen not in use the table may bev moved to an out-of-the-way position by loosening. the

. clamp 19 and sliding it toward clamp 16 with the result that the table is raised and swung over the head of the bed into the position shown by dotted lin-es in Fig. 2. To prevent uthe table and yokefrom tilting too far beyond the bed a spacing member 24 is applied over the guide member 14 so as to prevent the clamp 19 being moved closerto clamp 16 than is shown in the drawing with the result 'that the spacer 24 and bracing member 22 con tribute to hold the table and yoke in the upright position illustrated by the dotted lines.

The table 11 is secured on the cross bar of the yoke 12 by means of spaced guides or bearings 25 and 26 which in the embodiment illustrated comprise recessed angle members of short length. Intermediate these bearings is the means for clamping the table at the desired inclination which comprises a pair of spaced angle irons 28 forming a channel 27 between them as shown in Fig. G. A pin 30 passing between the sides ot the channel pivotally secures the clamp 29 in position. Clamp 29 passes around under the yoke 12 and when tightened holds the vyoke firmly against the guide bearings 25 and 2G. For tightening the yoke 29 the screw 31 is provided which has a head 33 countersunk into the table while a square shank 3st non-rotatably secures the screw in the channel 27. rThe end portion ot the screw engaging the wing nut 32 is threaded so that this nut may tighten the clamp 29 against the yoke 12 and maintain the table 11 in adjusted position.

lith the table in out-of-the-way position over `the head of the bed the clamp 19 need not be tightened inasmuch as gravity acting on the` table and yoke is sutiicient to maintain the table in position and the clamp 19 against the spacer 24, but to avoid accidental lowering of the table in case ot jar it may be advisable to tighten the clamp 10 on at least Vone side ot the bed.

In the form illustrated in Fig. S the yoke arm and table are similar to those already described, but the manner of mounting them on the bed is different, In this case the clamps 16 and 19 are slidably mounted on the slide rails 35, which are held in a position spaced laterally from the side members 13. A stop arm 36 is hinged to one ot the clamps 16, the forward end of arm 3G being Jformed with a plurality of holes 37 for adjustable connection with a slide 38 mounted on the slide rail 35. A spacer 39 is also slidably mounted on rail 35 between the clamps 16 and This type of mount-ing provides for convenientadjustment with simplified', control. Thus by changing the connection of the slide 38 with the holes 37 the height of the table above the bed may be varied. Once the slide 38 is secured to a eert-ain hole ot' the series 37 the table `is lixed at a certain height, but due to the sliding mounting ot the clamps 16 and 19, and slide 33, the table can easily be moved backward and forward by the patient. The spacer 39 acts to limit the movement of the table to its out-ot-the-way position after the arm 36 has been released from the slide 38.
