COLLAPSIBLE HIGH CHAIR.

Specification of Letters Patent.

Patented Dec. 14:, 1915.

Application filed November 18, 1914.. Serial No. 872,804.

To all whom it may concern:

Be it known that I, LEO M. SMITH, a citizen of the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Collapsible High Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in high chairs of the collapsible type and has for its primary object to provide such a device Which may be folded or collapsed easily and quickly and when folded stored into comparatively small space, the tray for the chair being removable so that it may be cleaned easily and effectively, and the chair used by children not desiring a tray.

Another object of my invention is to provide a high chair in which the seat and back are hinged to the legs and the arms are carried by the back, the seat being arranged to cooperate with certain of the supporting legs so as to hold the legs and seat in assembled relation and the arms being arranged to cooperate with the other of the supporting legs so as to hold the back and arms in proper relation to the seat and to one another.

Another object is to provide a high chair of simple construction that may be easily and expeditiously folded or assembled, which is simple as to construction, and inexpensive to manufacture.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts.

Figure 1 is a perspective view of my improved high chair assembled, Fig. 2 is a vertical sectional view taken through the chair, Fig. 3 is a detail fragmentary perspective View of the tray looking at the under side thereof, and Fig. 4 is a fragmentary detail perspective view of one of the arms looking at the under side thereof.

Referring to the drawings by characters of reference, 1 and 2 designate front and rear supporting legs that are crossed and pivoted at their intersecting points by means of a horizontal rung orrod 3 extending transversely through the legs and connecting each pair thereof. The upper ends of the legs 1 are disposed rearwardly of the upper ends of the legs 2 and hingedly connected with said legs 1 at their upper ends is a back support t of skeleton frame work preferably. Hinges 5 secure the legs 1 with the back 4.

I provide a suitable preferablyrectangular seat 6 that is provided at its forward end and on opposite sides with trunnions 7 that are journaled in the upper end portions of the legs 2. Vertical and upwardly directedextensions 8 are formed on the upper end of the legs 2 and are arranged to supportarms 9 carried by the back 4:. Carried upon opposite sides of theseat 6 aretrunnions 10 arranged to engage in slots or recesses 11 formed in the upper ends of the legs 1 in the inner faces of said legs. Thetrunnions 10 engage in the closed ends of the slots or recesses 11 as shown in Fig. 2 when the seat is in horizontal position as shown in Fig. 2 in the drawings. It will be seen when theseat 6 is in operative position the legs 1 and 2 are prevented relative movement and the feat maintained in operative relation to the egs.

Thearms 9 are each pivoted at their inner ends to one of thevertical frame bars 18 of the back l upon the inner face of each bar and extend considerably beyond thevertcial extensions 8 on the legs 2. Anopening 14 is formed in the under face of each of thearms 9 adjacent to the free end of each arm. Carried upon the upper end of each of thevertical extensions 8 is alug 15 which engages in theopening 14 in the correspond ing arm. This arrangement holds thearms 9 and back 4 in operative relation to one another and to theseat 6. Formed on the inner face of each arm and in the bottom face of each arm at points on opposite sides of the opening 14: arerecesses 16. Therecesses 16 are designed to receivetrunnions 17 carried at the ends of arectangular tray 18 of the ordinary type. Thetray 18 is rectangular and engages at its ends the opposed faces of thearms 9 adjacent to the outer ends of the arms. Hooks 19 are pivoted upon the under face of thetray 18 adjaoent to the ends thereof and are designed '9 against being pulled upwardly from engagement with the extensions 8 I- providehooks 21 that are pivoted upon the inner faces of theextensions 8 and are arranged to cooperate witheyes 22 carried upon the under faces of thearms 9.

I provide afoldable foot rest 23 that is pivoted as at 24: to the lower end of downwardly and forwardly inclined supportingbars 25. Thebars 25 are pivoted as at 26 to the legs 2 adjacent to the upper ends thereof and upon the inner faces of the legs.Extension bars 27 extend rearwardly from thefoot rest 23 and are provided adjacent to their ends and in their upper faces withrecesses 28 to receive the rung or connectingrod 3 to hold the foot rest in horizontal and extended position.

To eollapse'or fold the chair assuming that it is assembled as shownin Fig. 1, thearms 9 are unhooked and moved out of engagement with theprojections 15 on thevertical extensions 8. When this is done the back 4 may be let down and will hang in vertical position from thehinge 5 at the upper ends of the legs 1. After this is done thetray 18 is removed from the arms by unhooking the hooks 19 and forcing the tray downwardly relative to the arms so that theprojections 17 will be moved out of therecesses 16. Theextensions 27 are then moved out of engagement with therod 3 as shown in Fig. 2 the device may be folded in the desired position upon the upward movement of theseat 6 to withdraw thetrunnions 10 from the recesses 11 in the legs 1. It will be readily seen that my improved high chair may be folded into compact form and so as to take up little space. Thetray 18 may be removed when desired and the arms retained in operative position.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.

What is claimed is 1. A collapsible high chair including supporting legs, certain of the legs having slots in the upper end thereof, a seat pivoted to the other legs, trunnions carried by said seat and engaging in the slots in said slotted legs, a back hinged to said last named legs, arms pivoted to the back and means to detachably secure the arms to the legs to which the seat is pivoted.

2. A collapsible high chair comprising crossed supporting legs, a back hinged to the upper ends of the adjacent legs, arms pivoted to the said back, means to detaehably se cure the arms to the upper ends of the other legs and a seat hinged at the front to the adjacent legs and detachably interlocked with the other legs and maintained in such interlocked position by the back.

3. A collapsible high chair including supporting legs, aback hinged to certain of the supporting legs, a seat hinged to the other of the supporting legs and detachably connected with the legs to which the back is secured and engaged by the back to hold the seat rigidly in position for use, arms pivoted to the back, and means to detachably connect the arms with the legs to which the seat is pivotally secured.

4:. A collapsible chair including crossed supporting legs provided at the front of the chair with upwardly projecting extensions, a seat hinged to the legs between the extensions and detachably interlocked with the legs at its rear end and aback hinged to the legs with which the seat is interlocked and retaining the same in its interlocked relation, an arm extending forwardly from the back and detachably secured to the said extensions of the legs.

' In testimony whereof I aflix my signature in presence of two witnesses.

LEO M. SMITH.
