3 Claims.

This invention relates to new and useful improvements in a babys high chair.

More specifically, the invention proposes the construction of a device arranged in a manner to be supported upon the back of a chair or other object and into which a baby may be seated.

Still further the invention proposes the construction of a babys high chair characterized by a horizontal frame having an open front side with a seat member located therebeneath and provided with a table board slidably mounted across the open front side of the frame to permit the same to be moved to an inoperative position providing a clearance for permitting the child to be conveniently placed upon the seat member or removed therefrom.

A further object of this invention is the application of a means to the underside of the table board cooperative with a complementary member upon'the frame arranged tohold the table board in an operative position across the open side of the frame.

A further object of the invention proposes a means for releasibly mounting the cooperative locking member mounted upon the frame in a. manner to permit the same to be moved to free the table board and permit the same't'o becompletely removed from the frame.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to thefollowing description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The babys high chair, according to this invention, includes a horizontal frame 58 constructed of side arms 10* connected at their rear ends by a rear arm It to form a U-shaped frame having an open side. Means is provided for supporting the frame I0 upon the back of a chair I l or other object. This means comprisesah'ook l2 pivotally attached to the rear arm W of the frame l0 and having an upwardly extended hook portion l2 engage'able over the back of the chair H. When the hook I2 is in position upon the back of the chair I l the frame ill will be support ed in a superimposed position spaced from the top of theseat l3 of the chair H. The hook 12 has its bottom ends extended into a tubular re ceivingsocket M forme'd'on the top edge of'a plate I5 which is securely attac'hed 'to the face of the rear arm Ni Several screws H5 securely attach this plate to the rear arm.

A plurality of support strips ll extend downwards from the arms of the frame l I and support a seat member I3 upon whichthe baby maybe positioned. Each of these support strips H is alike in construction and consists of separate sections l'l and ll whichhave their adjacent ends hingedly connected together. The top ends of thesection I! are pivotally attached to the arms of the frame 10 by means of a hinge 19. The bottom ends of the section H are similarly attached to the top face of the seat member 18 by means of hinges 28. Thisconstruction permits the support strips H to be collapsed to draw the seat member l8 into close proximity to the bottom edges of the arms forming the frame I'll.

This collapsed position of the seat member and tween the bottom section and the plates 2| is accomplished in the extended position of the support strips and thus limits outward pivoting. As indicated by the dot and dash lines in Fig. 5 it is only possible to pivot the sections |'l and N of the support strips inwards.

A table board 23 is slidably mounted on the front portion of the frame I. This table board 23 comprises a board portion which has its side edges slidably engaging grooves 25 formed in the inside faces of the side arms Ill of the frame In. The outer edge of the board portion 24 carries a strip 25 which is engageable between the front ends of the side arms Ill when the board portion 24 is in its operative position to complete.

the frame l0 and close the open front thereof.

A means is provided for holding the table board 23 in several positions upon the frame Hi. This means comprises a pivotally mounted lever 26 mounted on the bottom face of the board portion 24. A bolt 21 passes through the board portion 24 and the rear end of the lever 26 for pivotally supporting the same on the board portion.

A rod 28 is fixedly mounted between the front ends of the side arm lll of the frame and in close proximity of the bottom face of the board portion 24 of the table board 23. When the lever 26 is extended forwards as shown in Figs. 3 and 4, if an attempt is made to slide the table board 23 outwards as indicated by the dot and dash lines 23', the lever 26 will strikethe bar 28 and limit outward movement. However, it is possible to pivot the lever 26 to an inoperative position parallel to the bar 28 to permit the table board 23 to be moved outwards until the lever 26 again strikes the bar 23. However, the movement in this pivoted position of the lever 26 will be much greater providing a large unobstructed space through which the legs of the child may pass when placed in the high chair and when removed therefrom.

A flexible strap 29 has its top end secured to the same bolt 21 which attaches the lever 26 to the bottom face of the board portion 24. The bottom end of the strap 29 is attached ,to the top face of the seat member M by means of a bolt 36. This strap 29 extends vertically upwards at the front center of the seat member l8 and is adapted to be straddled by the legs of a child positioned within the chair to prevent the child from slipping out from between the adjacent faces of the seat member l8 and the table board 23.

The back edges of the seat member l8 and the rear arm "l of the frame II! are provided with felt strips 3| where these portions engage the back of the chair I I to prevent these surfaces from being scraped and marred while the chair is being used.

The operation of this form of the invention isas follows:

"The hook I2 is engaged upon the back of a chair II or other similar support member for supporting the frame ID in a horizontal position above the seat l3 of the chair. ZGravity will pull the seat member l8 of the highchair downwards extending the support strips IT .to open the high chair. The lever 26 is then pivoted to an inoperative position parallel to the bar 28and the table board 23 is moved outwards enlarging the space between the rear edge of the board portion 24 and the rear arm ||l to permit a child to be conveniently placed within the chair. After the child has been positioned upon the seat member l8 with its legs straddling the strap 29 the table board 23 is moved back to its normal position and the lever 26 is pivoted to its operative posi tion at right angles to the bar 28. This limits any further outward movement of the table board 24 until the lever 26 is again pivoted to its inoperative position. When the chair is not in use the hook l2 may be pivoted to a position parallel to the frame l6 and the seat member I8 may be drawn in towards the frame H) by pivoting the support strips I! to reduce the compass of the chair and permit the high chair to be conveniently carried about or stored.

According to the modification of the invention shown in Fig. 10 the construction of the babys high chair is similar to that previously described, except for the provision of a rubber strip 3| which is attached to the back face of the rear arm .H] of the frame Hi. This rubber strip 3| takes the place of the felt strips 3| and is mounted within a groove 32 formed in the rear face of the back arm. This rubber strip 3| is adapted to engage the back of the chair II and prevent the same from being marred.

According to the modification of the invention shown in Figs. 11 to 14, the construction of the babys high chair is similar to that previously described except for the provision of a means for removably mounting the bar 28 between the front ends of the side arms Ill of the frame which permits the same to be completely removed so that the table board 23 may be completely slipped from its engaged position with the grooves 25 formed on the inside faces of the side arms W of the frame. In this form of the invention the bar 28' is formed with reduced ends 28 which engage bayonet slots 35 extended inwards from the front ends of the side arms I6 of the frame In. These reduced portions 28 are provided with threads and are adapted to receive thumb nuts 36 which are adapted to be tightly screwed against the outside faces of the side arms Ill for securely holding the bar 23' in position upon the frame Ill.

However, it is possible to loosen the thumb nuts.

36, freeing the bar,28' to permit the ends 28 to be, passed out of the bayonet slots 35 to permit the table board 23 to be completely removed from the open side of the frame In.

In this form of the invention a wider plate 2| is illustrated to be supported by hinges l9 to provide a better support for the back'of the child.

In other respects this form of the invention is similar to the previous forms and like parts are identified by like reference numerals.

While I have illustrated and described the preferred embodimnts of my invntion, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
