CHAIR Filed May 25, 1937 k r vafar 7 22 A". fiz/me/rz Patented May 24, 1938 UNITED STATES PATENT OFFICE CHAIR ration of Wisconsin Application May 25,

3 Claims.

The invention relates to chairs and more particularly to high chairs. It is an object of the invention to provide a high chair with a tray which can be conveniently adjusted or removed for cleaning purposes.

A further object aims at providing inexpensive and yet eifective means for permitting adjustment of the tray and releasably locking said tray in adjusted position.

Another object aims at providing adjustment means for a tray which facilitates complete removal of the tray.

Other equally important objects will become apparent from a perusal of the invention com prising the means described in the following specification, particularly pointed out in the claims forming a part thereof, and illustrated in the accompanying drawing, in which:

Fig. l is a perspective View of a high chair constructed in accordance with my invention.

Fig. 2 is a bottom plan view of the tray.

Fig. 3 is an enlarged section on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary section on the line 4- of Fig. 3.

Fig. 5 is an enlarged section on the line 55. of Fig. 3.

Fig. 6 is an enlarged section on the line 6-6 of Fig. 4, and

Fig. 7 is a fragmentary bottom plan view of the tray showing the links in separated position.

Ihe high chair comprises a seat I6 supported by legs II and equipped with a back I2. Side arms i3 are supported by rungs I4 and are provided with longitudinal grooves I5 extending on the inner side from the forward end to a point midway of the arms.

A tray, generally designated by I 6, is adapted to rest on the arms I3 and is provided on the underside with angle irons ll secured to the tray by a plurality of screws I8 and having its depend ing leg turned in to provide a flange I9, which enters the groove 45 of the adjacent arm. E'ach angle iron is formed at the center with a slot 2% extending the entire length of the horizontal leg to provide clearance for links 2| and 22.

The link 2i is secured to a center plate 23 pivctally supported from the underside of the tray by a screw 24 or other securing means, and the link is articulated to the remote end of the plate 23 as at 25. Likewise, the link 22 is articulated to the remote end of the plate as at 26. A spring 21 connects the joint between the link 22 and the plate 23 with the link 2| at the point 28 so that the links are normally held in contracted position.

The link 22 is formed at the outer end with a handle 29 which has a tongue 30 to cooperate with teeth 3| on the outer side of the adjacent 1937, Serial Ne. 144,648

arm I3. The link 2! is provided with a hooked end 32 adapted to enter a groove 33 in adjacent arm I3.

In use, the handle 29 is pulled outwardly whereby the links are separated so that the tongue 3|] and the hook 332 are released from the appertaining grooves and the tray may be slid forwardly and rearwardly for adjustment.

The tray may be completely removed from. the chair, if desired, when the same is to be cleaned. Upon release of the handle 29, the links 2|, 22 are pulled together under the action of spring 21.

While the drawing shows a preferred embodiment of the invention, numerous changes and alterations may be made without departing from the spirit of the invention.

I, therefore, do not limit myself to the details of construction and arrangement, as shown, but wish to include all changes, modifications and revisions constituting departures within the scope of the invention, as defined in the appended claims.

I claim:

1. In combination with a high chair having side arms, a tray superposed on said arms, angle irons secured to the underside of said tray, each angle iron having a flange" extending into a groove provided on the inner side of the adjacent arm, a pair of links movably secured to said tray, each link extending through a slot in the adjacent angle iron and provided with a hook to engage a groove on the outer side of the adjacent arm, and means for normally maintaining said links in arm engaging position.

2. In combination with a high chair having side arms, a tray supported on said arms, guide members secured to the underside of said tray and engaging said side arms, a pair of links movably secured to said tray, each of said links extending through a slot in the adjacent guide member, one of said links having a hook to engage a groove on the outer side of the adjacent arm, the other of said links having a tongue in engagement with a rack provided on the adjacent side arm, and resilient means for maintaining said links in arm engaging position.

3. In combination with a high chair having side arms, a tray supported on said arms, guide members secured to the underside of said tray and engaging said side arms, a pair of links movably secured to said tray, each of said links extending through a slot in the adjacent guide member and provided with a hook to engage a groove on the outer side of the adjacent arm, a handle secured to one of said links, and spring means for normally maintaining said links in arm engaging position.
