SERVICE ATTACHMENT FOR BEDS Filed March 1, 1932 2 Sheets-Sheet 2 Patented Oct. 17, 1933 SERVICE ATTACHMENT FOR BEDS Duncan F. McRae, Fort San, Saskatchewan,

Canada Application March 1, 1932, Serial No. 595,979, and in Canada February 8, 1932 3 Claims. (01. 45-82) The invention relates to improvements in service attachments for beds and an object of the invention is to provide an attachment having drawers, a table and a tray all suspended from the side rails of the bed and mounted so that they can be moved as a unit to any position between the head and foot of the bed and also so that such parts when not in use can be conveniently stored wholly underneath the bed.

A further object of the invention is to arrange the table so that it can be adjusted in height and also adjusted in position towards or away from the bed and this without interfering with the storing of the table in its not in use position I underneath the bed.

1 A further object of the invention is to arrange the tray so that it can be adjusted in position towards or away from the bed as well as be moved bodily with the rest of the attachment from end to end of the bed.

A still further object is to construct the whole attachment in a simple, durable and inexpensive manner and so that it can be placed on a bed without requiring any alteration in the existing bed structure and'also such that the completed attachment has a neat and pleasing appearance in either the folded or extended positions of the parts thereof.

With the above more important objects in view, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings, in which:

Fig. 1 is a perspective view of a bed equipped with my invention.

Fig. 2 is a cross sectional view at 2-2 Figure 1.

Fig. 3 is an enlarged detailed vertical sectional view at 33 Figure 2 and looking outwardly.

I Fig. 4 is an enlarged detailed vertical sectional view at 44 Figure 2 and looking inwardly. Fig. 5 is an enlarged detailed vertical sectional View longitudinally through one of the sliding arms and parts associated therewith. 4 Fig. 6 is a perspective view of a portion of the service table.

Fig. '7 is an enlarged detailed horizontal sectional view at 77 Figure 2.

In the drawings like characters of reference indicate corresponding parts in the several figures. The device is herein shown as associated with the well known type of hospital bed which embodies the well known side rails 1 and 2 connecting the head 3 and foot 4 of the bed. The bed spring is indicated at 5.

In carrying out my invention, I secure horizontal tracks 6 and 7 permanently to the side rails of the bed, these being herein shown as angle irons with the horizontal flanges inturned to pro-. vide the tracks. The tracks extend from one end of the bed to the other so that parts suspended therefrom can be readily moved iromthe head to the foot end of the bed as desired. Opposing pairs of spaced rollers 8 and 9 ride each track; these rollers being rotatably mounted on the outturned ends of vertical shanks 10 permanently fastened as by spot welding to metal supporting I straps 11 bent in the shape best shown in Figure 3 where it will be seen that they provide opposing inturned shoulders 12 and have their downturned ends terminating at their lower extremities in inturned fingers 13 which support and are securely fastened to the opposing edges of a bottom board 14. 1

To the straps, I secure permanently opposing side boards 15 and 16 which have a lengthapproximately equal to the width of the bed. A top'board 17 is fastened to the upper edges of the side boardsand the top and bottom boards and side boards provide an open ended boxlike casing to slidably receive pull out drawers 18 and 19, the drawer 18 being somewhat larger than 19 and both drawers being provided at their outerends with suitable pulls or knobs 20;

The drawers are guided in the well known manner by side strips 21 permanently attached thereto and slidably operating in receiving grooves 22 provided in the side boards. These drawers can be used to receive desirable material, that 18 being used say for personal effects and that 19 as a service drawer.

To the upper side portions of the opposing straps 11, I permanently secure a pair of opposing similar transversely extending supporting rails 23 and 24, these rails resting on the shoulders 12 and being actually of channel iron cross section with the channels opposing. The supporting rails receive slidably within the channels a pair of opposing side arms 25 and 26 also of channel iron cross section and these side arms are provided 100 with longitudinally extending guide slots 27 which receive in each instance a stop pin 28 carried by the adjacent supporting rail. The inner ends of the supporting bars are connected by a cross strip 29 and the outer ends of the side bars are attached 105 in any suitable manner to vertically disposed downwardly extending guides 30 of channel iron. cross section and having the opposing flanges thereof provided with a series of spaced holes 31 receiving stop pins 32. The opposing guides 30 1 0 are adapted to receive the lower ends of similar table supporting legs 33 which when in use take a vertical position as shown and have their lower ends resting on the pin 32. Obviously one can adjust the position of the legs by placing the pins in the different openings 31. The legs are provided in their outer faces with longitudinally extending guide slots 34 each of which receives a pin 35 permanently carried by the upper end of the guide 30 and here it will be observed that the outer ends of the channels of the sliding arms are open as indicated at 36 and that the pins 35 are located centrally of such channels.

The result of this is that when one raises. the

legs to their uppermost positions as limited'by the pins 35 striking the lower ends of the slots 34, he can then swing the legs outwardly around the said pins to a horizontal position and can then slide the legs endwise into the channels of the sliding arms which is their stored position. The outer or upper ends of the legs support a folding service table 37 and collapsible means is provided for holding. the table firmly in the extended position as shown and for permitting of the ready folding of the table into a position between the legs so that it canbe stored with the legs between the slidingv side arms.

The upper or outer ends of the legs are connected permanently together by a cross bar 38 and the outer end of the table is pivotally connected as indicated at 39 to the upper ends of the legs, the latter cross bar being positioned sufficiently below the pivot point 39 so as not to interfere with the folding of the table between the legs. To each. of the legs, I pivotally attach opposing brace rods 40 which have their free ends connected together by a cross rod 41 and it will here be observed that the brace rods 40 are quite clear of the sides 37 of the table and that the ends of the cross rod project beyond the upper ends of the brace rods.v The sides of the table are both supplied with angularly disposed guide bars 42 which form, with the top of the table, stop corners 43 to receive the projected ends ,of the cross. rod and operating as best shown in Figurev 6 to. support the table in a horizontal position at right angles to the legs. The lower edges of the table sides are each supplied with an inturned flange 37 and this is provided to support the extending end of the cross rod after the same has been released from the notch and during the time that the table is being brought to folded position- By observing Figure 6, it will. be seen that if one raises the free end of the table, he can release the ends of the rod from the bars 42 and having released them can then' enter them in the space above the flanges 37 and that once this isdone, the table can be folded down and the ends of the rod will then slide along the flanges. The partsv previously described provide a very convenient arrangement as one can adjust the height of the table by manipulating the pins 32 and can position the table as desired to the side 1 or over'the bed by sliding the side arms 25and 26 1 side armswith legs and table then slid under the bed on the supporting rails 23 and 24.

At the side of the bed opposite the table, I have located a service tray or shelf 44 and this shelf is also arranged so it can be stored wholly underneath the bed or extended a greater or less amount as desired to the side of the bed. The sides of the shelf are slidably carried in sliding side arms 45 and 46 of channel iron cross section and similar to those 25 and 26. The sliding arms 45 and 46 are slidably received within the channels of the supporting rails 23 and 24 and the supporting rails are provided with stop pins 47 operating in slots 48 provided in the latter arms and. serving to limit the out pulled position of the side arms. The sides of the tray are longitudinally slotted as indicated at 49 to receive stop pins 50 carried by the outer ends of the side arms 45 and 46'and operating to limit the out pulled position of the tray.

It will be observed that in the stored position of the side arms 25 and 26, 45 and 46, they are wholly underneath the bed spring so that no part of the device or attachment projects beyond the sides. of the bed when the same is not in use. The whole device is obviously mounted on the siderails of the bed so it canbe bodily shifted. to any desired position between the head and the: foot of the bed and as it embodies. the drawers,. table and tray, the wholeappliance is very desirable for the purpose for which it is designed as it can be readily positioned. for the greatest convenience of the patient, doctor or nurse.

While I have entered. into a detailed descrip-- tion of the various. parts employed, still it is tov be: understood that the same could be readily modified in their structure without departing from the spirit of the inventionas set forth in the appended. claims.

What I claim as my invention is:

1. The combination with the side rails of a bed, of lengthwise extending tracks permanently secured to the rails, a pair of transversely extending spaced parallel supporting rails underlying the tracks and having their ends terminating within; the width of the bed, rollers riding the. tracksand supporting the latter rails, opposing, interconnected pull out side. arms slidably carried by the: supporting rails, means limiting the out pulled position of the side arms, a pair of legscarried by the side arms, said legs being foldable. for storage purposes between the side arms, a table pivotally carried by the legs and foldable. therebetween and means for holding the. table and the legs rigidly in selected positions.
