ROSENTHAL BABY CHAIR BED 2 Sheets-Sheet 2 Filed Jan. 16, 1961 INVENTOR n HARRY -ROSENTHAL Patented Aug. 14, 1962 fire 3,049,376 BABY CHAIR BED Harry Rosenthal, 304- Lake Circle Drive, Portsmouth, Va. Filed Jan. 16, 1961, Ser. No. 83,013 9 Claims. (Cl. 297-320) This invention relates generally to improvements inv a baby chair bed and more particularly to a device having a locking mechanism for selectively securing the parts in one of a plurality of chair positions or in an extended bed position.
In the past recent years, there has come into popularity a type of childs bed which converts easily from a bed to a chair or vice versa, to that the child may be fed while in a sitting position and immediately thereafter, without movement from the device, placed in a reclining position for napping. The conventional devices of this nature generally provide only a single chair position and a single reclining position. Usually, also, these articles of furniture do not provide for positively locking the device in either one of such positions so that there is a danger of the bed suddenly converting to a chair while the baby is reclining in slumber by reason of a shifting of the weight of the child. This, of course, awakens the child, and there is always the danger of physical injury to the child arising from a sudden shifting of the bed parts.
Accordingly, it is a primary object of this invention to provide an improved baby chair bed comprised of hinged back rest and seat members which are adjustable and lockable in extended aligned positions and in a plurality of folded chair positions.
Another important object of the invention is to provide a baby chair bed, of the above described characteristics, which is positively lockable in its selected positions to ensure support of the childs body without danger of suddenly changing the positions under his weight or shiftings thereof.
A further object of the invention is to provide an improved baby chair bed, of the above described characteristics, wherein is provided a latching means for securing the device in its selected positions and which latching means is easily and simply releasable with economy of movement by grasping the back rest member to adjust the parts to another position.
Yet another object of the invention is to provide in a chair bed of the above described characteristics, a latching mechanism embodying a spring biased latch having a manually operable lever conveniently located for engagement by one hand while simultaneously grasping the back rest with the same hand to change positions of the bed parts.
Still another object of the invention is to provide an improved baby chair bed of the above described characteristics, which is of simple construction and easily and economical to fabricate.
The novel features that are considered characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description or a specific embodiment when read in connection with the accompanying drawings wherein like reference characters indicate like parts throughout the several figures and in which:
FIG. 1 is a perspective view of a baby chair bed embodying the invention and showing the device with the back rest and seat members in their extended positions for reclining;
FIG. 2 is a rear elevation of the baby chair bed shown in FIG. 1 but with the device converted to a chair;
FIG. 3 is a fragmentary side elevation showing a porat its inner edge with a tion of the back rest member and the latching mechanism supported on the rear thereof;
FIG. 4 is a sectional view taken from line 44 of FIG. 2 and looking in the direction of the arrows with alternative positions of the back rest and seat members shown in broken lines; and
FIG. 5 is a fragmentary sectional view taken from line 55 of FIG. 2 and looking in the direction of the arrows.
Referring now more particularly to the drawings, wherein is shown a preferred embodiment of the invention for illustrative purposes as comprising an improved baby bed chair, generally indicated by the reference numeral 10, and having spaced side panels 12 and 14 arranged in vertical parallel relation. The side panels are secured in such arrangement by means of a pair of cross braces 16 and '18 of U-shaped construction which are fastened to the panels by means of screws 20 and nuts 22. Disposed between panels 12 and 14' is a body supporting means, generally indicated as 24, and having a back rest member 26 and a seat member 28 hinged together at 30 along a pivot axis perpendicular to the side panels. The back rest member 26 is constructed of a relatively stiff, rigid board 32 covered with a relatively soft, cushion layer 34, adapted to protect the child when placed against the body support means, and a cover 36 of plastic or other suitable decorative material. The seat member 28 is similarly constructed and upholstered as are the side panels 12 and 14, this being conventional and forming no part of this invention.
The mechanism for adjustably supporting the back rest and seat members and lockably securing them in selected positions is best illustrated in FIGS. 2 and 4. The mechanism includes a pair of journal plates 38 secured to the inner surfaces of the side panels 12 and 14, approximately centrally of their length and below their vertical centers by means of screws 40 and nuts 42 appearing at the outer surfaces of the panels. A rod, or shaft 44 is journaled in the plates 38 to extend transversely across the space between the side panels and said rod is fastened to the lower rear surface of back rest 26 by means of the clips 46. Thus, the back rest is free to pivot about an axis defined by the shaft 44.
At the bottom center of the seat rest member 28 is fastened at least one bracket plate 48 extending downwardly and parallel to the side panels. Preferably a pair of brackets 43, respectively adjacent each side are used .to increase stability. The bracket 48 has an arcuate slot .50, inclined slightly upwardly in a forward direction for sliding reception of a transverse rod 52 seated in drill openings in the ends of the brace 18 and thus suitably fastened to the side panels 12 and 14. The seat member 28, being hinged to the back rest 26, is free to fold in relation thereto and during such folding action, to slidably adjust itself with respect to the fixed support rod 52.
In addition to the rod hangers 44 and 52, and for the purpose of fixing the relative positions of the back rest and seat members in a plurality of selectable positions, there is provided a third support or hanger 54 in the form of a U-shaped rod whose arm ends are turned outwardly and pivotally received in drill openings 56 in the ends of brace 16. Thus, the hanger 54 is free to pivot with respect to the side panels and its bight is slidably received between a latch plate 58 and the rear surface of the back rest member 26. The latch plate 58 is provided plurality of notches 60, three being shown, which when they receive the bight of hanger 54, lock the body supporting means in one of three chair positions. The latch plate 58 also has an additional notch 62 for reception of the hanger 54 when the body supporting means are extended in substantially horizontal, aligned positions and the device is adapted to receive a child reclining thereon, as on a bed surface.
The plate 53 is welded, soldered, or otherwise fastened to a rod 66 which is journaled to rotate in right angle brackets 68 fixed to the center of the back rest member 26. At its upper end, rod 66 is bent outwardly at right angles to form a projection 70 which is within convenient grasping distance of a hand clutching the top edge of the back rest 26. A coil spring 72 is mounted about rod 66 and has one projecting end 74 engaging the rear surface of the back rest member 26, with the other projecting end portion 76 engaging a surface of the latch plate 58 and normally biasing the plate 58 into its latching position perpendicular to the rear surface of the back rest member 26 and filling the space between rod 66 and the back rest member.
The latch plate 53 has end flanges 64 which, in such normal position, rest against the back rest member and stop further rotational movement of the latch plate. This condition is best illustrated in FIGS. 4 and 5. When the latch plate is in latching position, the rod lever projection 70 extends at a small angle away from the back rest member 26. Vfnen, however, the lever 70 is pressed toward the back rest member, the rod 66 is turned against the pressure of the coil spring 72, swinging the latch plate to the position shown in FIG. 3 and indicated in phantom lines in PEG. 5, whereby the hanger 54 no longer is trapped within one of the notches and is free to slide in the space between the latch plate and the back rest member.
It will be apparent from the above description, that to operate the improved baby chair bed from its chair position shown in full lines in FIG. 4, it is merely necessary to grasp the top of the back rest member 26 with one hand pressing the lever 76 toward the back rest member to turn the latch plate 58 and unlock the hanger 54 from the lowermost notch 69 in which it is engaged. With the same, or a simultaneous, motion, the back rest 26 may be moved counter-clockwise, as viewed in FIG. 4, to any one of the other chair or bed positions forcing the hanger 54 upwardly in the space between the latch plate 58 and the back rest 26, as indicated by the arrows in FIG. 3. When a desired chair position is reached, it is necessary merely to release the grasp on lever 70 and spring 72 will automatically turn the latch plate 58 to engage one of the other notches 60 with the hanger 54.
When the hanger 54 is engaged in one of the notches 60 or 62., the back rest and seat members 26 and 28 are firmly locked in the selected position as illustrated in broken lines in FIG. 4. The same procedure is followed when it is desired to place the back rest in a substantially horizontal position, the operator in such case, moving the back rest as far in a counter-clockwise direction as he can so that the hanger 54 will engage in notch 62 when the lever 7 is released. To reverse the movement, and convert the device from a bed to a chair, the back rest upper edge is again grasped and pressure exerted on lever 7 0 to release the hanger 54, but the direction of the motion imparted to the back rest is in the opposite sense, the back rest being moved clockwise as viewed in FIG. 4. When the desired chair position is reached, lever 70* is again released to latch the body supporting members in the selected folded condition.
Although a certain specific embodiment of the invention has been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
