To all whom 'it may concern: I i

Be it known that L ONATHAN LEE KNIGHT, citizen of the United States, residing at Fond du Lac, in the county lof Fond du Lac and. State of Wisconsin, have invented certain new and useful Improvements in Mezzanine-Chairs', of which the following is a specification.A

This invention relates to chairs and chair attachments,l and aims primarily to. provide a chair. particularly adapted for use` by children and capable of being attached to anv ordinary full sized chair to support the child in elevated position one whichmay be used `as a swing; and, one which may be used as a hammock.

One aim of the invention is tol so construct the chair attachment that it may be readily adapted to any ordinary chair back" and to provide for vertical adjustment of the seat with respect to the back so that the seat may be positioned at the desired elevaf A further aim, of the invention` is to so construct ,the chair .attachment that. the parts thereof may bel readily disconnected and packed in a small space so as tobe readily carried from place to place.

The invention further aims to so construct the attachment that the attachment may be used as an ordinary chair or as a hammock. A

For a full understanding of the invention reference is to be had tothe followingdescription and accompanying drawing, in which y x Figure 1 is a perspective view of the attachment embodying the present invention, the same being illustrated as applied to the back of an ordinary chair. Fig. 2 is avvertical longitudinal sectional yView therethrough. Fig. 3 is a bottom plan View of the seat of the attachment. Fig. 4 is a perspective View illustratingl a connecticn between certain of the parts of the attachment. Fig. 5 is a verticaltransverse sectional view illustrating the means of holding the seat of the attachment at the desired elevation.

Corresponding and like parts are referred to in the following description andindicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, the attachmentis i-llus-A trat-ed as substantially in the form offan ordinary chair except for the absence of the usual legs. The back of the attachment lcomprises standards, each including a lower section 1 and'l an upper section 2, the sections Qbeing tted telescopically in the respective sections 1 and being formed with openings 3 to receive a stud 4 at the free end of a leafspring 5 which is secured upon each of the lower sections' 1. projectthrough openings in the said sections 1, .whicl openings register with lthe openings 3, and the upper sections 2 are in this Lmanner held -at adjustment 'in the said sections 1. The upper'ends of the sections 2 of thestandards above described are connectedl by means of a cross rung 6 which is removably threaded at its lends into elbow joints 7 the upper ends of the said sections The studs 4' 2 being also threaded into t-hesejoints.- The I back further includes a rung 8 which eX- tends across between ythe sections 2 below the rung 6, each of the sections 2 being `formed with a socket 9 having bayonet slot10'therein and the rungsv being provided at each end with a stud 11 engaging in the respective socket 9. By means of a like connection oneicr more rods 12 are supported between the 'ungs 6 and S.

A rung 13 extends across between the upper ends of the sections 1 of the standards of the back and .a similar rung 14 connects these sections of the standards near-"their lower ends. In connecting the rungs 13and 14 with the sections 1\of the back standards, sockets havingbayonet slots, and studs 2O into which the forward ends of t-he armrests and the upper ends of the standards `19 are threaded.'l The lsections 1 of the back standards and the respective standards 19 are formed or provided with alining sockets 21 into which are iitted the endsof the side members 15, and the standards 19 are also formed with alining sockets into which are (itted the ends of the member 16. y

The seat proper* of the. device lis in the nature of a suitablelength. of clothor carpet 22 provided at its forward side with a hem 23 and at itsrear side with a hem 24. A

flap 25 is stitched or otherwise secured toV the under side of the 'seat 2'2 transversely of the'intermediate portion thereof and is provided witheyelets 26 through which is laced a cord 27. 'In `arranging the seat within the frame, the member 16 of the seatsframe is inserted in the hem 28 of the seat and the rung 13 is .inserted in thel hem 24e.4 The ,cord 27 is then laced about the rung 14 land thrughv the eyelets 26, whereupon the seat will be supported in substant-ially the manner illustrated in Fig. 2 of the drawings. Y I

Rings 2 8 are supported loosely from the arm-rests 17 and through these rings may ,are provided suspension devices, each of which includes a hook 29 which is swiveledto the lower Iendof the shank 30 of 'a hook 31, and these hooks 29 of the suspension def' vices are interchangeably engageable with the rungs 6 and 8 at any lpoint in their length, Vwhereas the hooks 31 are engaged over the top of the back oi an ordinary l chair upon which the 'device is tobe supported.' These latterhooks are preferably rubber covered so as -not to injure the finish of the chair. As stated, I the hooks 29 may be engaged with the rung v8 at any 'point in its lengthand consequently the device embodying the invention may be supported by chair sections of different widths. Also, due to the fact that. the hooks arelconnected by a swivel joint, the curvature of the chair back will not interfere with the engagement of the hooksil therewith.

It will be at times desirable to rest the device of the invention directly upon the seat of an ordinary chair and in order that rear standards at each side oi the finish of the chair seat may not.bein-' I jured, rubber pads 32. are' fitted upon the lower ends of the standard sections 1 and the standards 19.

` The'ihanner of applying. theidevice to anv vordinary chair back will be readily apparent from inspection of F ig. l of the drawing, and when the device is to be used as a swing, suspensionropes may be secured at their lower e'nds through the ring 28 and the device suspended-in proper-position.

Shouldit be desired to use the device in a manner similar to thexuse of a hammock,

lthe lacing string 27 is to' be untied and the seat 22 will then vconform to the of the occupant ofO the device. e

` Having thus 'described the invention what is claimed as new is- 1. A seat of theclass described, comprisposit-ion ing a seatframejncluding front and rear frame members, 'aback including 'a rung, a seat'. proper comprising 'a `flexible sheet of material attached at' its front end to the front-fram'efmember of t e'seatirame and at its rear end to the rung of ,the back,"

.a `Hap secured' tothe. said seat between its said lends, they said flap. aving-eyelets,l and f f a lacing cord laced through the eyelets and around .therear frame. member of the seat frame. Y' Y 2'. In a ch-airattachment'of the class described, front and rear s tandrda' seatframe including side members detachably connected at' theirv ends to the front and ment and front and rear cross-members detachably connected at their ends to the front and rearv standards respectively, andv rungs .detachably connected at their Aends' tothe rear standards.
