CONVERTIBLE HICH CHAIR Filed Aug. 11, 1945 IN VEN TOR.

lie/"Z024 file/277mm Patented May 15, 1951 UNITED STATES PATENT OFFICE 1 Claim.

My invention concerns improvements in childrens chairs.

It has been found commercially desirable to provide a childs high chair which may be easily converted into a youths chair so that when the child becomes old enough to do without the conventional high chair arrangement the high chair need not be discarded and a youths chair purchased, but the high chair may be readily converted into a youths chair.

It is an object of my invention to provide a childs high chair having tray supporting arms of such construction that they may be readily detached from the chair to convert the chair into a youths chair without arms.

Other objects and advantages will be apparent to those skilled in the art from the preferred embodiment of my device which is shown, by way of example, in the accompanying drawings, in which:

Fig. 1 is a front elevation of a high chair which embodies the herein described invention;

Fig. 2 is a side View of the chair shown in Fig. 1;

Fig. 3 is a view on line 3-3 of Fig. 2; and

Fig. 4 is a view similar to Fig. 2 but showing the chair converted to a youths chair.

As shown in Fig. 1, the preferred form of my invention comprises a conventional high chair having an upright back I0, and a horizontal seat II with the usual four legs I 2. The arms l3 are supported above the seat by the uprights M. The arms I3 support a tray I5 having attached thereto flanges 16 which are received in slots 1! on the outside edge of the arms I3. A latching mechanism (not shown) is provided on the bottom of the tray I5 to secure the tray in adjustable position on the arms I3. The uprights l4 consist of substantially U-shaped members having inwardly directed legs or flanges I9 and 20. The legs I9 are adapted to be secured by screws 2| to the arms l3. The legs 20 of the uprights are adapted to be secured by screws 22 to the bottom of the seat adjacent the front thereof. The arms I 3 are secured to the back ID in abutting relation by screws 23. A brace member 24 is provided along the back edge of the seat and the back I 0 is secured to both the brace member and the seat by screws 25 and 26. The brace member 24 serves to provide securing means or sockets 21 for the rear legs 12. The sockets 21 may extend into the seat ll proper. This construction is necessary to give the back sufficient rigidity when the arms are detached.

When it is desired to convert the chair into a youths chair the arms [3 and the uprights l4 may be removed by simply removing the screws 22 which attach the uprights to the seat II and the screws 23 which attach the arms to the back l0. Plugs 28 may be provided to insert in the holes left by screws 23. The resulting youths chair does not have any unsightly marks or holes after the removal of the arms and uprights.

My invention may be applied to a high chair of the type having a swinging tray. The construction is the same as in the sliding tray type and the tray is removed as well as the arms and the uprights. In this instance the resulting youths chair is free from unsightly holes and marks in the same manner as in the preferred form.

In carrying out my invention various materials may be employed, as metal, wood or plastic. I prefer to construct the chair of wood except for the uprights I 4 which may be made of an appropriate metal or any other material having sufiicient strength and rigidity to rigidly connect the arms l3 to the chair seat 1!. The specific shape of the members should be such as to give a pleasing appearance to the chair as well as adequate strength at all times. It is understood that the specific materials and details of construction employed may be varied within the scope of my invention.

I claim:

In a chair adapted to be converted from a childs high chair to a youths chair, having a back and a seat, detachable side arms for supporting a tray thereupon, each of said side arms comprising a top member detachably connected at one end to the back of the chair and extending from the back to the front of the seat along the side of the seat and a channel-shaped forwardly positioned upright member having inwardly directed, top and bottom flanges with the top flange connected beneath the top arm member and the bottom flange detachably connected beneath the seat whereby said side arms may be readily removed from the chair.
