Application October 24, 1944, Serial No. 560,131 y This invention relates in general to a folding back and arm rest which may be supported in any suitable manner, but is more particularly described in connection with a vertical head board of an ordinary bed construction.
An important object of the invention is to provide a folding back and arm rest structurev no1'- rnally housed or contained in an upright support such a-s a head board, conforming to the style or decoration thereof so that when folded, it appears to be a part of the head board itself, but when unfolded, it presents side arms and a back structure inclined to the head board and projecting forwardly therefrom to provide an arm and back support for a person sitting in the bed.
A further object of the invention is to provide a folding back and arm structure in which the parts thereof may be inclined at various angles to each other and to the support.
A still further object of the invention is to connect the folding back and arm portions for movement together in accordance with the desired inclination thereof.
A still further object ofthe invention is to provide a folding arm structure of this kind having a recess at its outer end with a closure therefor in which very small articles may be conveniently disposed.
A further object of the invention is to provide a new and improved folding structure combined with the head board of a bed in which the bed or mattress will constitute a supporting seat, and the arms and a back rest will be supported by the head board.
Other and further objects of the invention will appear in the specification and will be apparent from the accompanying drawings in which Fig. l is a perspective ofthe head end of a bed having an upright head board in which this invention is contained, the outer surface of the back and arm structure having a padded cover conforming somewhat to the decorative design of the head board;
Fig. 2 is a front elevation of a head board with a folding back and arm rests in accordance with 6 claims. (c1.v 5-72) Fig. 4 is a detail view showing the hinged end `of a covered arm structure;
Fig. 6 is a view similar to Fig. 5 showing the back and arm rests at a different inclination;`
Fig. '7 is a transverse sectional view showing the connection between the arms and the back rest;
Fig. 8 illustrates a portion of an arm supporting `'plate having three different rod engaging portions;
Fig. 9 illustrates an arm rest with a recess closure at the end; and
Fig. 10 illustrates the end of an arm rest having a recess with a top closure. This invention is particularly designed and intended for application to any head board or bed structure so that it may be used a-s a back and arm support for those who wish to sit up or read in bed. It may also be used for invalids in connection with hospital and other beds, and it may have more general application in connection with 'an upright support adjacent to a seat in any desired connection or location.
In the present invention, the unfolding or swinging down of the arms also moves the back to an inclination, or to one of several different inclinations depending upon the engagement of the arm structure. Referring now more particularly to the drawings, a bed Il is shown in Fig. 1 having a head ,board with an outer decorative cover I2 in which may be incorporated a particular design comprising a number of vertical padded segments' or flutes of which outer ones I3 and I4 are mounted to swing downwardly to form arms, and the intermediate ones I5 are connected to the arms to .swing outwardly to provide a back rest.
or brought into use or moved into position in front of the head rest whenever desired.
As shown in Fig. 2, a head board I6 shown without the cover I2 has a recess I1 in which a panel I8 forming a back rest is supported by hinges I9 at the top thereof and side panels 20 also mounted in the recess at the sides of the panel I8 provide arm rests each of which is connected at the lower edge of the recess by a hinge 2|.
The two arms 20 at the sides of the back rest are connected for joint movement by a rod 22 extending through side pieces 23 and 24 of each arm. The ends of the rod are threaded to receive fastening nuts 25 and 26 engaging opposite sides of the outer side piece 24, and the outer nut preferably being seated ln a recess 2 which makes the outer face threaded at least flush with the outer face of the side 24. The rod itself is prevented from rotation in any suitable manner as by means of a set screw 23 inserted through a side piece 23 and engaging the rod.
'I'he coordinating rod 22 also extends through slots 29 in side plates 3B at the edges of the back I8 so that the movement of the arms causes a corresponding movement of the back I8. If desired, the rod 22 may engage in the lower ends of the slots 29 to hold the arms in corresponding inclined positions at all times.
If preferred, the slots 2Q may be formed with a lateral extension 3l for engaging the rod 22 and thereby holding the arms and also the backn at different corresponding inclination. As shown in Fig. 8, a side piece 32 may have a slot 33 with three recesses 34, 35, 3% at the lower end for engaging' a rod 22 at any one of three different inclinations and thereby holding the arms and the back in three relatively diierent inclinations.
" The extremity of each arm may be provided asshown in Fig. 9 with a recess 3l having a small i removable drawer Vor a closure 38 opening at the end thereofA with a 1snob 39 recessed within the endsso that it will close within the opening l1 as the arm is closed.
' If desired, one of the arms may be provided with. a recess 4i! opening from the top adjacent the endthereof and having a sliding closure 4I movable outwardly from' the end. To uncover the recess, the arm must be moved outwardly from the head board recess l1.
It is also contemplated that the arm structure asish'own in Fig. 4 may be upholstered or provided with any suitable cover l2 corresponding to the decorative design and material of the bed itself. The entire arm'Y may be covered or only the top surface thereof, if upholstered, and when the top surfaceonlyis covered with an upholstered pad, it will'be disposed at the back of the head board whenv the arm structure is folded.
A tab 43 may be attached at the lower end of th'eback for pulling it and the arms outwardly and'frictional fasteners or snaplocks (not shown) may be disposed to engage the upper ends of the arms or the lower end of the back with the edges of the'opening if desired.
This construction may be applied to a single bed" or two of them may be applied to a double bed, or the folding structure may be applied to an upright adjacent an ordinary wall seat for use as a chair when desired. This folding structure may even be incorporated in a wall, not visible when folded, but usable with a movable seat arranged below it by simply extending the arms and back when desired.
The arm structure may also be mounted in a head board or on an upright support such as a wall, at a spaced distancerapart such that a bedmattress or a seat may be disposed beneath the.' arms in outwardly extending position so that theyV will provide the arm rests of a seat of which the intermediate portion of the support is the back. Pillows or other back supporting means may beplaced at the back between the arms thus forming a suitable seat structure.
Various other constructions, combinationsVv and arrangements of the folding arm and back structure may be adapted without departing from the Yspirit and scope of the invention.
I claim: l; The combination with a bed having a head board having a recess, of a back panel movably mounted in the recess of the head board to swing outwardly at the bottom above the surface of the bed, a pair of arms also m'ovably mounted in the recess of the head board to swing downwardly at the sides of the back panel and above the surface of the bed, and means connecting the back panel and the arms for moving them together outwardly and downwardly respectively from the head board to form an inclined back and the side arm structure of a seat of which the bed forms the bottom of the supporting seat.
2. A folding back and arm rest structure, comprising -a-n upright support having a recess therein, a baci:V hinged at the upper edge of and normally seated in the recess, a pair of arms hinged at the bottomVV of the recess at the side of the back` and normally seated in the recess, a transverse bar extending between the said arms, and a slotted connection carried by the back through which the bar extends for moving the back in accordance with the movement of the arms and for limiting the downward movement of the arms.
3. A folding'back and arm rest structure, ccmprising an upright support having a recess therein, a back hinged in the upper edge-of the recess, a pair of arms at the sides of the back hinged at the lower edge of the recess, a transverse bar connecting the arms for joint movement, and a slotted` connector carriedV by the back through which the bar extends, the lower end of the connector having a plurality of recesses for engaging the' bar at difierent elevations.
4. A foldingback and arm rest structure, comprising an upright support, a back hinged at its upper end to the support, a pair of arms coextensive with the vertical dimensions of the back, disposed at the sides thereof and hinged to the support at the lower ends of the arms, a bar connecting the armsfor joint movement, means for securing the ends of the bar to the arms, and a slotted support in connection with the back through which the bar extends for coordinating the movements of the arms and back.
5. A folding back and arm rest structure, comprising an upright support having a recess therein, a back adapted to be'seated in the recess and pivoted at the upper edge, of the recess, a pair of arms adapted to be seated in the recess to form rests at the sides of the back and pivoted in the lower edge of the recess, coordinating means connecting the back and arms for joint folding and unfolding movement, and an opening at the outer end of the arm structure which is moved to a covered position within the edge of the recess when the arm is folded in the recess and is accessible at' the end of the arm when the structure is moved outwardly from within the recess.
6The combination with a bed having a head board` with a recess in that portion above the horizontal bed surface, of a back hinged at the upper edge of the recess, a pair of arms at the sides of the back hinged at the lower edge of the recess, the back and arms being coextensive in height to fold within-the recess and the outer surfaces thereof then conforming to the design of the head board outer surface so that they do not appear as a back or arms when folded, a bar extending transversely connecting the arms, slotted members supported by the baci: through which the bar extends for moving the back in accordance with the movement of the arms and for limiting the downward movement of the arms to a position above the bed surface, thereby providing the seat formed by said bed surface with an inclined back, and extending arms when the back and arms are unfolded from the head board.
