NURSERY-CHAIR.

Specification of Letters Patent.

Patented Mar. 22, 1910.

Application filed June 15, 1907. Serial No. 379,137.

To all whom it may concern:

Be it known that I, JOHN WV. HnNoKn, citizen of the United States, resident of Cleveland, county of Cuyahoga, State of Ohio, have invented a new and useful Iniprovement in Nursery-Chairs, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention relates to nursery chairs, and particularly to chairs of this kind that are adapted to be folded up when not in use.

' In other words, the object of the invention is the provision of a childs traveling toilet that can be used in automobiles, railroad cars, steam boats and hotels and which can be carried without inconvenience in a trunk or suit-case.

To the accomplishment of the above and related objects, said invention consists of the means hereinafter fully described and particularly pointed out. in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represents in perspective, a chair embodying my several improvements in its open or operative condition; Fig. 2 is also a perspective view of the same but in partly closed or folded condition; Fig. 3 is a side elevation of a portion of the chair as it appears in its completely closed, or folded, condition; Fig. 4: is a side elevation, from within, of a detail of the chairs construct-ion; Figs. 5 and 6 are corresponding side elevations from within of a certain operative detail as applied to the respective side doors of the chair; and Fig. 7 is a cross-section and plan view of one such detail, taken on the line 77, Fig. 5.

Referring to such drawings, the main element of the chair will be seen to consist of the back A with which all the other parts are either directly or indirectly connected and against which they are adapted to be folded in the closed, or inoperative, condition of thechair. Such back A comprises, in the preferred form illustrated, Figs. 1 and 2, a metallic frame a of inverted U shape and dimensions chosen to conform with the use to Whichthe chair is to be put. The back rest proper consists of a sheet a of veneer, leather, fiber, or fabric suitably attached to the sides and top of frame a by means of clips a At a suitable height above the bottom edge of the frame a, the sides thereof are connected by a shaft c to which is pivotally attached the seat B, and also a cover 6 adapted to close thereover or to fold along with such seat against the back A as desired. In its open, or operative, position, the seat B is designed to be sup ported at its outer or free end by a front B that preferably consists of a closed panel as shown to the sides of which are rigidly secured arms or bars Z2 pivotally attached laterally of the seat near such forward end and extending upwardly, the upper ends being connected with the back A by what is in effect a compensating parallel motion as will hereinafter appear. In the open position of the seat B, in which it is designed to be supported by front B, the latter inclines downwardly and outwardly from such seat so that its lower edge lies without the inner edge of rounded recesses Z2 in the front edge of the seat, one on each side of the latters median line, whereby the contour of such front edge is made substantiallyv that appearing in Figs. 1 and 2. By means of the construction and arrangement of front B such front being a closed panel as stated, a sloping foot-board is in effect provided and the child using the chair is thus prevented from drawing his feet back far enough to permit him to get up alone. He is thus prevented from standing up and pushing or upsetting the chair backward. The advantage residing in having the front edge of the seat recessed as described, should be obvious; since thereby the child is obliged to spread his knees apart, and he is thus involuntarily induced to adopt a position that is at once more comfortable, as well as free and hygienic, than would otherwise be assumed.

Extending for some distance along the back of frame a. above the point of pivotal attachment of seat B thereto, are secured supplementary bars a Figs. 1, 2, 5 and 6, that form guideways in which is movably held a transversely disposed bar 0. To the respective ends of the latter are pivoted the rear ends of the arm C which thus are seen to have sliding pivotal engagement with the chair back. A laterally projecting lug a near the upper extremity of each such guideway is so disposed as to support the rear end of the corresponding arm C, when horizontally extending, Fig. 1, and to secure the same against the back A when alined therewith, Fig. 3. To the outer portion of the arms are pivotally secured the upper ends of the bars Z) utilized, as previously stated, in attaching front B to seat B. This pivotal connection with arms C is not had directly but with the cross bar of a U-shaped frame or bracket 0, the spaced ends of which are slidably mounted upon such outer arm portions. Upon such arms is supported a tray 0, the ends of which are secured to the respective arms at two points, one in front of, and the other between the two ends of the slidably mounted U-frame 0. The connections of the tray C at one end are made detachable so as to permit the same to be swung about the arm as an axis. Two catches 0 are adapted independently of each other to secure such free end of the tray against the disengagement described. Chance loosening of the tray by the child, naturally inquisitive as to fastenings of this sort, is thus rendered more diflicult.

By virtue of the sliding pivotal engage ment of the arms C with the chair back A, and with the lateral prolongations b of front B, it will be seen that in the folded condition of the chair, the frame composed of the two arms C, the bar 0 connecting their rear ends, and the tray 0 joining their forward portions, is adapted to be shoved bodily down. The length of the chair in its folded condition is thus adapted to be shortened by the range of movement allowed by the guides a and the ends of U-frames 0, and the height of back A so made the maximum dimension of the device. At the same time by the locking action of lugs a, when the arms 0 are thus closed alongside frame a, assisted by an outwardly disposed lug 0", Figs. 1 and 3, mounted on the inward hinge of tray C so as to similarly lock members I), the chair is securely held together when folded and can only be opened by positive actuation of its parts, having such end in new.

To additionally support the seat B as also to laterally inclose the lower portion of the chair, sides, or doors, B are provided, such sides being pivotally attached at their rear edges to the corresponding lower portions of the frame a of the chair back. In their outer, or extended positions, these panels fit neatly within the spaces bounded by such seat B and outwardly inclining front B. They are furthermore provided at their lower outer corners with hooks 6 Fig. t, adapted to engage with lugs or pins Z2 mounted upon contiguous inturned flanges front B. Each of said sides furthermore bears inwardly directed lugs 6 near its rear edge that are engaged by levers b pivotally secured to the back of the chair so that oscillation of such levers is adapted to cause the corresponding side to swing inwardly or outwardly as the case may be. The upper ends of levers extend into proximity wit-h the rear portion of the seat B, their upper portions being provided with cam grooves b with which engage pins secured in such seat. Oscillation of the levers will thus be obviously had upon movement of the seat. The respective cam grooves are of diverse conformation so that the oscillation of the corresponding levers, and thereby of sides B is not had simultaneously but successively. The two sides are thus adapted to be folded in one upon the other and thus to automatically, by merely raising the seat B, close the same against the back A.

The operation of my device should be fairly obvious from the foregoing description of its construction. It will be evident, in other words, that by simply raising or swinging upwardly arms C together with tray 0, whereby their outer portions are connected. seat B will simultaneously be raised and folded against back A as will also the swinging front B by virtue of the link motion connecting the same with the back. Movement of the seat, as has just been explained, is furthermore adapted to automatically fold inwardly the two side doors B of the chair so that by a single movement the entire device is folded up close and into small compass. The compass thus occupied is still further reduced by retraction of the armsC with tray C, down the slideway A whereby the length of the device as a whole is materially decreased. This retraction of the arms and tray is furthermore utilized to lock the several members constituting the device in the closed position into which they are assembled.

Any suitable chamber may be employed in connection with my improved chair; or, if preferred, a collapsible pouch of the type shown and. described in my pending application, Serial No. 298,433, filed January 29, 1906, may be used instead, to this end lugs I), Fig. 2, are provided on the underside of seat B for the attachment of such pouch thereto.

To assist levers in swinging side doors fully into their outer positions, as well. as to securely retain the same in such positions once they are attained, I provide a cam faced lug Z) on the under side of seat B near each lateral edge thereof, Figs. 2, and 6. These lugs are disposedv well to the rear and the action should be obvious. Conversely to prevent the sides from swinging out farther than they should, the frame a Z) that bound the respective lateral edges of] of chair back A is provided with a forwardly directed lug a Figs. 1, 2 and 7, that engages the corresponding door and serves as a stop therefor.

Other methods of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
