Patented Feb. 13, 1934 COMBINATION CHAIR AND HIGH CHAIR Giovanni Agati, San Francisco, Calif.

Application June 27, 1933. Serial No. 677,926

2 Claims.

The present invention relates to improvements in a combination chair and high chair, the principal object of the invention being to combine with the ordinary dining room chair a collapsible high chair which is disposed underneath the seat of the dining room chair, and which may be disposed in active position by lifting the seat on a hinge to rest against the back of a chair, and by a simple upward movement of a member of the collapsible high chair.

It is further proposed to provide a collapsible high chair in such a manner that the same is completely accommodated within the space defined by the seat box of the chair so that when collapsed it does not in any way interfere with the regular use of the chair as a dining room chair.

The present invention is an improvement over that described and claimed in my Patent No. 1,243,913 of October 23, 1917, and contemplates the introduction of a number of improvements and refinements in the combination chair and high chair shown in said patent.

More particularly it is proposed in the present invention to provide an improved hinge for the seat of the chair by means of which the seat when in normal position may be made to abut directly against the back of the chair so as to create the appearance of a fixed seat, while on the other hand the seat may be raised into vertical position.

Another contemplated improvement is the provision of a guide means for guiding the collapsible high chair when in collapsed position during the operation of converting the chair into an ordinary dining room chair, whereby the collapsible high chair is confined within the through my combination chair and high chair,

the high chair being shown inactive position;

Figure 2 a similar vertical section showing the high chair in collapsed position;

Figure 3 a fragmentary detailed View illustrating the hinge for the chair seat with the latter in horizontal position;

Figure 4 a horizontal section along line 44 of Figure 2;

Figure 5 a perspective view of a bracket used in my device; and

Figure 6 a perspective view of another bracket used in my invention.

While I have shown only the preferred form of my invention, I Wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached 1without departing from the spirit of the invenion.

In its preferred form my invention comprises a chair 1 made in the conventional fashion of a dining room chair, and comprising legs 2, a seat box 3, and a back 4, the uprights of which are preferably made integral with the rear legs. The seat box' comprises a front member 5, two side members 6, and a rear member '7. A seat 8, which may be of any suitable construction, is adapted to rest on the seat box and is hinged to the sides 6 in the manner indicated in Figures 1 and 3, the principal object of this hinge structure being to allow the seat to make a close fit with the rear member '7 of the seat box, and the rear legs, whereby my chair is given the same appearance as the ordinary dining room chair, and whereby any danger of catching the clothes of a person sitting on the chair is prevented.

The hinge structure is shown particularly well in Figures 1 and 3 and comprises a plate 9 secured to the inner face of each side 6 and a bracket 10 secured to the under-face of the seat and having a depending flange 11, having an upwardly extending lip 12 extending into the seat material, which is suitably recessed for this purpose. A link 13 connects the seat to the seat box by being pivoted to the lip 12 as at 14 and to the plate 9 as at 15.

Aside from this direct link connection between the seat and the seat box which allows of forward movement of the seat when the front edge of the seat is raised, I provide means for controlling the extent of the forward movement in a second link connection comprisingthe link 16 pivoted to the plate 11 as at 17, and the link 18 pivoted to the plate 9 as at 19, the two

links

16 and 18 being interconnected by a floating pivot 20. An arm 21 swingable on the pivot 15 is connected to the link 16 asat 22. It will be noted that due to this construction when the seat is raised the arm 21 will first urge the seat forward sufliciently to make the seat clear the rear memher '7, and the rear legs, so that theseat may be raised into vertical position in the manner shown in Figure 1 without any marring of any of the surface of the chair, and without the necessity of rounding any of the corners, as for instance, in the chair shown in my patent. On the return movement the seat will also in a similar manner return to practically horizontal position. while remaining spaced from the back of the chair, and will impinge upon the back and make a close fit therewith during the last stage of the return movement.

The seat has accommodated underneath the same a collapsible high chair including in its principal features an auxiliary chair seat 23, arms 24 connected to the seat by means of links 25, and braces 26 adapted to lock the seat in active position. The auxiliary seat 23 is hinged to the main seat substantially midway of the length thereof by means of brackets 27, one of which is shown in detail in Figure 5, the bracket including a vertical flange 28 fastened to the main seat, a horizontal flange 29 fastened tothe edge of the auxiliary seat by means of the pivot 30, and a small lip 31 extending horizontally from the vertical flange so, as to form a rest or stop for the rear of the'auxiliary seat when the latter is raised into the horizontal position shown'in Figure l. The pivot is disposed at a distance from the main seat so that when the auxiliary seat is collapsed, its front edge .32 .will swing into a position close to the rear edge of the main seat and the auxiliary seat will occupy the slanting position indicated in Figure 2.

The auxiliary seat is raised into active position by means of the arms 24 which are pivoted to the main seat by means of brackets 33, the arms being spaced sufliciently far to straddle the auxiliary seat 23 when collapsed. The brackets .33, one of which is illustrated in detail in Figure 6, comprise two flanges 34 held in parallelrelation by a web 35 so as to straddle the arm 24, the two flanges 33 having lips 36 projecting outwardly for fastening the brackets to the underface of the chair seat.

The arms 24 are connected to the auxiliary seat 23 by means of links 25, secured to the arms by means of links 3'7, and to the sides of the auxiliary seat by means of pivots 38, the links 25 being arranged in the vertical plane of the .arms 24 and being made to straddle the auxiliary seat.

The front ends of the arms are interconnected by means of a conventional tray 39 hinged as shown at 40 for swinging movement from an active position ontop of the arms to an inactive position in front of the arms. When in active position the tray may be locked to the arms by means of the spring latch 41 including a keeper 42 and a spring operated latch member 43 automatically engaging with the keeper when the tray assumes its active position.

The auxiliary seat 23 is automaticallyheld in its raised or active position by means of braces 26, formed with slots 44 adapted to ride on rivets movement from vertical position on top of the front member 5, to vertical position adjacent the front member 5., Normally this foot rest will assume the latter position, but when the front seat is raised, while the high chair is still in collapsed position, the foot rest 50,may be raised to vertical position on top of the front member 5, and then after the high chair has been positioned, the foot rest 50 may be dropped and its rear edges will come to rest on small clips 52 projecting from the braces 26.

When the high chair is collapsed with the main seat still in vertical position the auxiliary seat and. the arms and the tray will naturally fall by their own weight into substantially parallel relation to the main seat, but when the main seat itself is then dropped, the high chair elements have a tendency to drop away from the main seat, the tray 39 being the part that has a tendency to drop away to the most advanced position. It is apparent that if no means were provided for holding the collapsed high chair close to the main seat the arms 24 and the seat 23 would naturally fall into vertical position with the main seat in horizontal position. To insure accommodation of the collapsed high chair within the box 3 of the main seat, I provide a guide 53 which extends from the front member 5 to the rear member '7 of the box, and upon which the front edge of the tray 39 rides during the collapsing operation for holding the collapsedhigh chair close to the main seat. The front edge of the tray 39 is preferably provided with a small metallic reinforcing element 54 adapted to ride on the guide 53.

In operation when the chair is in a normal position with the main seat resting on the seat box, it does not distinguish from any other dining room chair, and there is nothing to indicate that it has any combination feature associated therewith. If the chair is to be used as a high chair, it is only necessary for the operator to raise the main seat by its front edge into vertical position, to turn the foot rest 50 upward, to raise the front edge of the tray 39, which will secure the collapsible chair automatically in the position shown in Figure 1, whereupon the foot rest 50 may be made to rest on the clips 52. For collapsing the chair the foot rest 50 is'lifted, the braces 26 are freed of their engagement with the rivets which causes the collapsible chair to drop into a position approximately adjacent the main seat, whereupon the main seat may be lowered, which would cause the front edge of the tray 39 to ride on the guide 53 and bring all the parts into the position shown in Figure 2, the foot rest automatically drop ping into suspended position during the operation.

I claim: v

1. In combination, a chair comprising a seat box, legs supporting the same, a back, a seat and means for hinging the seat to the seat box arranged to effect a slight forward movement of the seat when the latter is raised, the latter means comprising a single link having pivoted connection with the seat and the box respectively, a pair of links having pivotal connections-with the seat and the box respectively and having a floating, pivot between the same and an arm pivoted coaxially with one of the single link pivots and pivotally engaging that one of the pair of links which is pivoted to the seat for swinging the seat engaging end of the latter link and the seat forward when the seat is raised.

2. In combination, a chair. comprising a seat box, legs supporting the same, a back, a seat pivoted tothe seat box and adapted to be swung into vertical position to rest against the back, a collapsible high chair pivotedto the underside of the seat so as to be freely suspended therefrom in vertical position when the high chair is collapsed with the seat in vertical position and having a tray supported in front thereof and a guide rail supported by the seat box and extending from front to rear for guiding the tray and the collapsed high chair into substantially horizontal position when the seat is dropped into horizontal position. i
