HOSPITAL TABLE Patented Aug. 4, 1931 PHILIP E. GRAFF, OF EVANSTON, ILLINOIS, ASSIGNOR TO SIMMONS COMPANY, OF NEW i YORK, N. Y., A CORPORATION OF DELAWARE l I v HOSPITAL TABLE Application .filed September 14, 1925. Serial No. 56,146.

This invention relates to hospital tables and the like, in which it is desired to provide a table top which may be easily projected and supported over the bed so that a patient 5 confined to the bed may have easy, convenient use thereof.

The object of this invention is to provide such a table in which the top may be easily projected over the bed without danger of overbalancing the supporting frame and the consequent upsetting of the table. Another object is to provide a table having mea-ns for positioning the top at any desired height or at any desired horizontal angle relative to the table supporting structure. Another object is to provide a table structure which will be light in weight, of simple construction and which will have the necessary strength to withstand frequent moving and handling such as they receive in such institutions as hospitals. Further objects and advantages of my invention will appear when reference 'is had to the following specication when considered in connection with the accompanying drawings wherein I have illustrated a selected embodiment of my invention, in which:

Fig. l is a side elevation.

Fig. 2 is an end elevation.

Fig. 3 is a plan having certain parts broken away to better illustrate the construction.

. Fig. 1 is a section on the line 1 -t of Fig. 1.

Fig. 5 is a section on the line 55 of Fig. 2, and l l Fig. 6 is a section on the line (36 oi Fig. 5.

In the drawings, a stationary table top 10 Ais supported by a supporting frame 11. The supporting frame 11 comprises corner posts or legs 12, preferablyv of tubular construction, united by means of upper frame members 13 which are secured thereto by means of soldering, asv indicatedat 14, or any other suitable means. The stationary top 10 is supported on the members 13 and comprises tubular trame members 15 and a plate 16.

The members 15 may be secured to the supporting frame members 13 lby means of soldering, indicated at 17, and the top plate 16 may be secured to the frame members 15 by having its edges bent down over the sides of 'arm 37.

the frame members 15 and inwardly thereunder, as indicated at 18 and 19 respectively.

Frame lmembers 20-20 and 21-21 unite the legs at their lower ends and also serve as supporting members for a shelf 22 which may be conveniently secured thereto by having its edges bent down over the frame members and inwardly thereunder as indicated at 23 and 24 respectively, or any other suitable means.

A shiftable top 25 comprises a tubular frame 2G made up of

tubular members

27, 28, 29 and 30 secured together at their ends by soldering, as indicated at 31, or any other suitable way. Intermediate members 32-32 extend across the frame between 'the

aforementioned members

27 and 28 are secured thereto by suitable means such as soldering, and are provided for a purpose hereinafter set forth. A top plate 33 having its edges bent downwardly over the

frame members

27, 28, 29 and 30 is secured thereto by means of screws 34 which pass through apertures in the bent down edges of 'the top plate and engage threaded apertures in the frame members. Any other suitable means of fastening may be employed or the top may remain unsecured to render it readily removable for cleaning or so that it may be used as a tray it desired.

A sheet of cardboard, telt, or other suitable sound-deadening material may be interposed between the top plate 33 and the supporting

frame members

27, 28, 29 and 30, as indicated at 70, and the top plate 33 may have its edges somewhat raised as indicated at 71, to prevent any liquid which may be spilled thereon from running ofi. Stops 72 of telt or other material may be secured to the under side of the shiftable top frame members in order to prevent actual contact between the shittable top and stationary top thereby eliminating scratching or damaging of the stationary top surface.

The shittable top is supported on a post member 35 which comprises a downwardly extending leg 36 and a horizontally extending The horizontally extending arm 37 is provided with a cross member 38 secured thereto by suitable means such as soldering as indicated at 39, which member 38 is fastened /Y We! the post member 35.

to the frame members 32 by means of screws 40, as best shown in Fig. 3. The end of the horizontally extending arm 37 may conveniently be flattened as indicated at 4l, and

' projected through an aperture 42 in the inner Wall ofthe frame member 28 in order to support ythat edge ofthe shiftable top. Y

The downwardly extending leg 36 which is of circularvformation is received within a tube 43 and/is adapted to be rotated therein. The said receiving tube 43 is secured to the supporting frame l1 within a vertically ci;- tending member 44 which may be provided. with a reinforcing tube 45. A spring 46 may be disposed between 'the lower end 47 of the downwardlyextending leg 36 and the bottom 48 of the receiving tube 43. The yspring 46 serves to nor-mally raise the shift able top a slight distance to disenofage a locking means which will hereinafter be described. n

'A plate 49 secured to the stationary top 10 by means of screws 50-50 is provided with a straight edge 51. Another plate 52 secured'A to the cross members 32 of the shiftable top by meansl of screws 53-53 is provided with an edge 54 complementary to lthe edge 5lof the plate 49. By depressing the shiftable top against the spring 46 so that the

edges

51 and 54 are brought into engagement, the shiftable top is prevented from being displaced from a position overlying the stationary top. It is of course apparent that any number of positions may be provided by providing edges similar to the edge 51 of the plate 49 corresponding to 'the desired position of the shiftable top. j

Means for retaining the iocked position of the shiftable top comprises a U-shaped member 55 to which is secured a projecting screw member 56 which is adapted to be engaged by a hand Ywheel 57. The iid-shaped member' 55 is' apertured `as indicated at 53-53 to receive the 'downwardly extending leg 36 of y By turning the hand wheel 57'tlie member 55 is drawn into clamping engagement with the leg 36 and prevents thesame from bei-ng rotated or raised by the spring 46. The clamping member 55 vand screw 56 are anchored to the vertical post 44 by reason of the screw 56 projecting through an aperture 59 therein. A washer 60 may be 'provided between the-member 44 and hand wheel 5T to prevent excessive wear.

An eXtensible legG'l is adapted to be drawn out` asv indicated in dotted lines in Fig. l when the shiftable topv is rotated to prokject outwardly, as also indicated in Fig. l, to prevent tipping or upsetting of the table. This extensible leg`6l is preferably-of tubular construction and is slidably engaged with the supporting frame llr in the folowin-g manner: ,A pair of angle iron :guides 62-62 is `secured tothe supporting fstructurell b -means l'of projecting ears 'G3-'63 which project through apertures 64 in the frame members 21-21, as best shown in Fig. 5, and rest on the lower wall of the said frame meinbers. The said angle iron guidesl 62 are spaced apart, as indicated at 65, to permit passage therebetween of a pair of screw members 66 which members are anchored in the extensible leg 6l. Tear plates 67 and 68 are provided to slide back and forth on the guide members as the eXtensible leg 6l is drawn out orreturned to its inner position. Suitable casters 69 may be provided in the legs to render the table easily moved about.
