Y., A CORPORATION OF DELAWARE HOSPITAL TABLE Application filed February 6, 1930. Serial No. 426,218.

This invention relates to hospital tables or over-the-bed tables such as are used in hospitals, institutions and other places for the convenience of a person confined to a bed.

The objects of the invention are to provide a freely mobile or portable table of the class described; to provide such a portable table which will maintain itself in prearranged position and which will not be apt I? to roll, slide, or otherwise move out of the desired position by accident; to provide such j a table which is readily adjustable vertically to suit various requirements as to height; to provide a table in which the table-top is pivotally adjustable about a horizontal aXisso as to further suit the convenience of the person using the table; to provide improved means for maintaining the table-top in normal horizontal position and also in any desired pivotally adjusted position; to provide construction according to my invention.

In the drawings:

Fig. 1 is a perspective.-

Fig. 2 is a vertical section through the supporting post and table-top on an enlarged scale.

Fig. 3 is a section on the line 3 3 of Fig. 2.

Fig. 4 is a section on the line 4-4 of Fig. 3.

Figs. 5 and 6 are sections on the lines 5-5 and 66, respectively, of Fig. 2.

Referring now to the drawings, my improved hospital table includes a base element 1, a supporting post 2, a table-top 3, and means indicated at 4 for vertically adjustably mounting the table-top 3 on the post 2.

The base 1, in the present instance, includes a pair of substantially parallel spaced

end members

5 and 6 which are rigidly connected by means of a connecting bar 7 which extends between and is secured at its opposite ends

tosaid end members

5 and 6. As shown, the connecting member 7 is disposed intermediate the ends of the

respective end members

5 and 6. In the present instance, the base is formed of tubular metal members and the connecting member-7 is slightly larger in cross-sectional dimensions than the end members 5 and'6i The connecting member '7 is provided with openings at its opposite ends, such as indicated at 8,'through which the

end members

5 and 6 pass, as clearly indicated in Figure 1. These parts may be rigidly secured together in any suitable manner, for instance, by welding. End caps, such as shown at Sand 10, may be provided forelosing the opposite ends of the connecting member 7 and for improving the general appearance of the structure.

At the ends of the base end member -6, I provide vertically disposed foot members 11'll for receiving casters1212 by means of which the table is adapted to be moved about.

On the ends'of the base memberb, I provide foot members 1313, which are pref erably of a length equal to the combined length of the foot members 11- 11 and the casters 1212, so that the baseas a whole is maintained in a substantially horizontal and an outer, lower end reinforcing sleeve 15, which is provided with a trimming 16 at its upper end. These parts are rigidlysecured to the base by means of welding or otherwise at their lower ends, and a brace 17 extending diagonally from the post to the or rectangular tubular metal.

base part 7 is provided for reinforcing the connection between the post and base.

The table-mounting means 4 consists of a tubular metal member bent so as to provide a vertically disposed leg 18 which telescopes over the post member 14 and a horizontal leg 19 on which the table-top 3 is mounted. One wall of the tubular leg member 18 is provided with a series of vertically spaced openings, such as indicated at 20, for receiving the jaw portion 21 of a locking dog 22 which is pivotally mounted inside of the post member 14 adjacent the upper end ofothe latter. The locking dog 22 may conveniently be controlled by means of a pedal or button 23 carried bya rod 24 which is slidably mounted in suitable openings provided in the top and bottom walls of the end member 5 of the base. The rod 24 is pivotally connected to an arm 25 which extends lengthwise under the end member 5 and is pivoted thereto, as indicated at 26. Intermediate its ends, the arm 25 is pivotally connected to a rod 27 which extends upwardly inside of the post member 14, as clearly shown in Figure 2, and which is pivotally connected at its upper end to the locking dog. Aspring 28 disposed between a bearing plate 29 inside of the post member 14 and a stop 30 carried by the rod 27 serves to normally urge the rod upwardly and to move the jaw 21 of the locking dog outwardly into engagement with one of the openings 20 in the leg 18. The j aw 21 of the locking dog is preferably beveled so that the jaw may be readily displaced merely by lifting upwardly on the table-mounting part 4, while downward movement of the latter is positively prevented except when the button 23 is depressed to withdraw the jaw of the locking do Tn the present instance, the base and the table-mounting means are formed of square Obviously, the parts are not rotatable relative to each other, whereby the leg .19 ofothe mounting means 4 is maintained in normal position; i. e., extending laterally from the post into position overlying the base.

The table-top 3 is pivotally adjustably mounted on the leg 19 by means of bracket or bearing members 31 and 32 which are formed with annular flanges 33 and 34, respectively.

The annular flanges 33 and 34 fit over

drumlike mounts

35 and 36, respectively, so that the bearing members 31 and 32 are rotatable with respect to the said mounts and with respect to the leg 19. The

mounts

35 and 36 are rigidly secured to the leg 19 in any suitable manner, for instance, by welding.

' For maintaining the table in normal horizontal position, the bearing member 31 is provided with an opening 37 which is adapted to receive one endof a spring-pressed locking element 38. The lockingelement 38 is slidably mounted in a box-like bracket 39 which posite end wall of the bracket 39. The locking rod 38 is provided with a handle part 42 which is formed by bending the rod 38, and a rebent end portion 43 extends upwardly into a slot 44 provided in the leg 19 whereby the locking rod is held against rotation and the handle 42 maintalned 1n predetermined readily accessible position.

The table may be locked in various pivotally adjusted positions by providing a plurality of circumferentially spaced openings adapted to receive the locking rod 38, but I prefer to provide friction means for holding the table in its various positions of pivotal adjustment. In the present instance, the frictional holding means is provided by splitting the bracket or bearing member 32, as indicated at 45, and providing one leg 46 with a threaded nut element 47 and the other leg 48 with a sleeve 49. A clamping screw 50, passing freely through the sleeve 49 and threadedly engaging the nut 47 serves to tighten the split clamping element around its mount- 3, and it will be obvious that the holding effect of the split member 32 may be adjusted as desired.

The table top 3 may conveniently be made of sheet metal of the desired thickness, and it is preferably provided with down-turned end flanges, such as indicated at 51 and 52, and upturned side flanges 53 and 54. In order to provide a smooth edge on the upturned flanges 53 and 54, and also for the purpose of strengthening the structure, marginal side portions of the tabletop are rebent as indicated at 55 and 56 so as to form two-ply side edge portions.

Cross brackets or straps 57 and 58 are secured at their ends to the re-bent marginal portions underneath the table top as clearly shown in Figure .6, and the mounting bearings or brackets 31 and 32 are preferably secured to these cross bars, thereby avoiding the use of fastening means visible on the upper side of the table top. As clearly shown in Fig. 5, the bracket member 31 is secured to the cross bar 58 by means of rivets, and as shown in Figure 6 the bracket 32 is secured to the cross bar 57 in a similar manner. In order to permit adjustment of the holding power of the bracket 32 on the drum 36, the leg 46 of the bracket 32 is adjustably secured to the bar 57 by means of a rivet 59 which passes through a slot 60 provided in the leg 46. The thickness of the cross bars 57 and 58 may be such that the bars will suitable strengthen the table-top and the upper heads of the rivets by which the brackets 31 and 32 are secured to the bars may conveniently be of such thick ness that the table-top will rest thereon and thereby be supported against sagging.

its

. base 1 under the bed until the post 2 is disposed closely adjacent one side of the bed. The table 3 will then be positioned over the bed in position overlying the base 1. The foot members 13-l3 of the base, which frictionally engage the floor, will, of course, prevent the table structure from being accidentally moved out of its prearranged position. 7 To move the table, it is merely neces sary to lift the friction-footed end oh the floor slightly, after which the structure may readily be rolled on its casters 12-12.

For preventing scratching or otherwise marring the bed structure, I provide a cushion element 61 on the table post, as clearly shown in Figures 1, 2 and 3. This cushion may be of any suitable material and may be anchored in a channel member 62 which is carried by a bridging strip 63. The bridgin strip 63 is more or less trough-shaped,as

., clearly shown in Figure 3, so as to bridge over the openings through which the locking jaw 21 pro ects and so that normal operation oi the locking aw is not interfered with. A

channel-mounting strip 64 is secured to the leg 18 and the bridging strip 63 is in turn secured to the said mounting strip. The openings 20 in the leg 18 are extended through the mounting strip 64, as clearly shown in Figures 2, 3 and 4:, so as to permit the looking dog to move outwardly to its full locking position, as shown in Figure 2.

The hospital table structure above described is exceptionally light in weight so that the same is easy to move from one place to another, wh le also being exceedingly strong, rigid and durable. The structure is also easy to keep clean by reason of its plane surfaces which may be coated with enamel, porcelain, or other appropriate material.

In addition to being convenient for manipulation by attendants, the table is readily adjustable as to height and inclination by the occupant of bed. The height oft-he table may be increased merely by raising the tabletop and mounting post, since the locking dog is automatically disengageable by such upward movement. Inclination of the table is readily adjusted from positively locked horizontal position, to the desired position, since the locking member is disposed adjacent one end oi the table-top in a position accessible to the bed occupant.
