8 Claims.

The main objects of this invention are:

First, to provide a table of the overbed type having a manually adjustable section which can be easily adjusted to a forwardly inclined position or to an inverted position.

Second, to provide a structure having these advantages in which the adjustment is accomplished merely byrotative manipulation of a rod or shaft.

Third, toprovide an adjustable top structure which may be adjusted with a minimum of danger or likelihood of the person effecting the adjustment being injured.

Fourth, to provide a structure having these advantages which is simple and rigid in construction and at the same time quite economical.

Further objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawings in which:

Fig. 1 is a front perspective View of a table commonlj designated as an overbed table embodying thefeatures of my invention.

Fig. 2 is a fragmentary rear perspective view of the structure of Fig. 1 with the adjustable top section adjusted to a forwardly inclined position.

Fig. 3 is a fragmentary view in transverse section on line 3-3 of Fig. 1 with the adjustable top section adjusted to a forwardly inclined position.

Fig, 4 is a fragmentary section on a line corresponding to line 3--3 of Fig. 1 with the top section in partially reversed position.

Fig. 5 is a fragmentary perspective view showing details of the adjusting sleeve or sleeve-like nut member. 7

Fig. 6 is a fragmentary view partially in vertical section showing a modified form or embodiment of my invention.

Fig. '7 is a fragmentary view partially in section showing still another modification of my invention.

The overbed table embodiment of my invention illustrated in the accompanying drawings comprises pedestal base members I having uprights 2 thereon. Coacting with the uprights are vertically adjustable upright members 3 carrying the bed or frame 4 of the table. The means for adjusting the members 3 on the members 2 are not illustrated further than the cranks 5 as this adjusting mechanism forms no part of my present invention.

The table is provided with Spaced relatively fixed top sections 6 and with an intermediate adjustable top section or panel I which in its collapsed position lies flush with the section 6 to provide a continuous top. This adjustable section I is carried by a support 8 which is hinged or pivoted at 9 to the table bed or frame 4. It will be noted that the pivots of the hinges H) are positioned adjacent to but in spaced relation to the front edge of the support 8. The top section 1 is pivoted to the rear edge of the support 8, the pivots being preferably the pintles of the hinges H, see Figs. 2 and 3. The panel 1 is designed to rest upon the support 8 and is tiltably adjusted therewith on hinges Ill as shown in Fig. 2 or it may be tilted on its pivot ll relative to the support in the manner illustrated in Fig. 4. The panel in the structure illustrated is provided with a mirror l2 on its under side.

The means for adjusting and adjustably supporting the panel I comprise the adjusting rod or shaft l3 which is rotatably and slidably carried by the brackets I4 and I5 secured to the under side of the adjustable support member.

. movement of the rod it is provided with a collarlike stop 2| which coacts withthe bracket [5. A pair of links 22 are pivotally mounted at 23 on a longitudinal bar 24 carried by the frame and at 25 on the journals or pivots carried by the sleeve. The links are curved or conformed to clear the bar 24. A coupling 26 is swiveled on the rear end of the rod and is connected by the link 21 to the rear edge of the panel 1.

With the parts thus arranged, assuming that the parts are in normal position, that is, that the adjustable panel support is in lowered position as shown in Fig. 1, rotationof the rod in counterclockwise direction causes nut member l8 to travel forwardly on red l3 and tilts the support and the panel carried thereby forwardly on pivot 9, the thrust of the rod being sustained by the stop or thrust member 2| so that the sleeve or nut member is moved forwardly on the, rod and, consequently, the links 22 swung rearwardly, resulting in the tilting of the top'section. It is effectively held in its tilted or adjusted position without locking means other than the nut or thread or worm engagement. In the event it is desired to tilt the section I on its rear pivots H, assuming the parts to be in their normal position, the rod is rotated in clockwise direction and the nut member l8 held in a relatively fixed position by the links. The rod is moved in the nut member with the result that a tilting pull is imparted to the panel to swing it upwardly through the swivel and link connection described. The same result is accomplished by the embodiment shown in Fig. 6 in which the section I is provided with a segmental rack 28 coacting with an annular rack 29 on the rear end of the rod [3.

In the embodiment shown in Fig. 7 the swivel member 39 to which a link 2'! is secured is provided with a longitudinal bore 3! receiving the reduced section 32 on the rod 13, this reduced section having an annular groove 33 which is engaged by the retaining pin 34 permitting the swivel or rotating movement of the rod within the member 39.

In all of these embodiments the manipulation is entirely from the hand wheel i6 which is so positioned as to be conveniently manipulated by the patient or user, and the parts are held in whatever their position of adjustment may be until further manipulation of the hand wheel. This minimizes the possibility of the patient or user being injured and also provides an adjusting means which is quite easy to manipulate.

I have not attempted to illustrate or describe certain other embodiments or adaptations of my invention which I contemplate as it is believed this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
