COMBINED CHAIR AND DESK.
Application led April Il,
T 0 all tolto/m. 'it may concern.:
Be it known that l, decor. d. Vfonrn, a citizen ot the United `tates, residing at North Manchester, in the county of l/llabash and State ot indiana, have invented Certain new and useful improvements in Combined Chairs and Desks, of which the following is a specii'ication.
The invention relates to a combined chair and desk with especial reference to the type suitable for use in the school-room, study or library. l l L The general ann ot the int/'entren is to provide an improved construction in a chair desk ot the movable unitary typewhich includes a chair having a drawer 1n the s eat section, and a single standard supporting an adjustable desk top.
Chair desks designed tor use in the. schoolroom commonly provide for the adjustable positioning ot the desktop for the convenient use of occupants of various ages and sizes. Such adjustments include a vertical adjustment of the top support, provision for sliding the top forward and back, and also an angular adjustment ot the desk'top. Heretotore the parts enabling these adjustments commonly have been constructed ot' metal, the interengaging metallic parts `requiring lubrication with consequent liability oi staining` the clothes ot the occupant, o r, without lubrication are practically-certain. to make a noise when moved, to the disturbance of the school-room.
.t is one of the more specific objects ot this invention to provide an. improved structure for the several. adjustments ol" desk. top in which the cooperating movable parts in each case are constructed respectively ot wood and metal, requiring no lubrication and. being noiseless in their operation.
A desirable jte-attire in a desk chair is tho abilityto set the top at an angle convenient for Work, and then move the top forward and back upon sitting in or rising from the chair, without releasing the angular adjustment. y
A further object is to provide ior the forward and back adjustment ot the desk top without disturbing its angular adjustment.` 1
Another obj ect of the invention is to provide an improved wooden standard for adjustably supporting the desk top, having 1921. serial No. 458,236.
bolts fixed in the standard ywhich engage slots in a sliding metallic bracket frame,
and which carry adjustable nuts arranged to clamp the supporting frame to the standard.
t is a further object of the invention to provide a neat and sightly chair desk or" simple and durable construction which may be cheaply manufactured and is capable ot long` e'licient service.
Other objects and advantages will be apparent in the following detailed description of a desk chair embodying the novel features oi my invention in its construction and arrangement of parts, and which l have illustrated in the accompanying drawings, in which Figure l represents a front elevation of my improved desk chair and Fig. 2 a side elevation of the same with portions broken away to illustrate the joint construction. Fig. 3' is a vertical sectional view ot the desk top and supporting standard taken longitudinally ot' the desk top. F fl is a vertical cross-sectional view ot the desk top illustrating the adjustable construction of its supports. Fig. 5 is a perspective view of the complete assembled desk chair.
Referring t0 Figs. l and 2, the numeral l indicates generally a back section comprising legs 2' extending upwardly to support back rests 3. A box-like seat section ft carrying a sliding drawer 5 is secured at the back to the legs 2 and supported at its front end at one side by a front leg'G and at the other side by a supporting standard 7. The standard 7, prefer-ably constructed of wood, extends upwardly above the level ot the seat and carries at its upper end a supporting traine S comprising a pair ot metallic brackets 9 positioned on the upper portion of the standard 7 and extending horizontally in front of the chair section. The spaced brackets 9 are rigidly connected by a metallic baselplate l0 which overlies the outer face of the standard 7, and are further braced by means of a pairv of cross members l()a fixed on the upper surfaces of the brackets 9. The plate lO is provided with rtwo parallel vertically arranged slots 11 through each of which extends a headed bolt l2, the` bolts being stationarily positioned in apertures passing through the Standard 7. The Outer end of each bolt elevationv of the brackets in'relation to the standard may be varied as desired` by sliding the inter-connecting plate up or down within the limits of the vertical slots.
construction permits any desired adjustment of the desktop to suit the convenience of the occupant of the chair.
A pair of spaced wooden slide bars 14 are longitudinally slidable on the upper surface of the brackets 9, and are secured against lateral and vertical displacement by angular metallic straps 15 secured to the upper surface of the brackets 9 inwardly of the spaced bars and extending up and over the upper surface of the bars. The inner ends of the slide bars 14 are pivotally connected by means of a pivot rod 14a with al pair 0f cleats 16 secured to the under side of a desk top 17. i
Depending from each of the slide bars 1.4 and positioned between the' brackets 9 is a fixed metallic plate 18 supporting` a` clamping rod 19 having its ends' passing through apertures in lthe lower ends of the respective plates 18. An enlarged head 29 is formed on the inner end of the clamping rod 19, the outer end being screw-threaded t0 receive a hand nut 21. .ifi spacer sleeve 22'is positioned on the rod 19k having its ends in abutment with the two depending plates 18. y
Pivoted to each of the supporting cleats 16 is an adjusting brace 23 positioned substantially above the clamping rod 19 and having a longitudinal slot 24 through which the clamping rod extends at its respectivev ends. The braces 23 are positioned in l-ateral contact with the outer surfacesof the plates 18. `Raising and lowering the desk top 17 onk its pivotal connection with the slide bars 14 operates to slidev the adjusting braces 23 upon the clamping rod 19 to the limit 0f the longitudinal slots 24. The enlarged head 20 of the clamping rod is positioned in abutment with one of the slotted braces 23 and the hand nut 21 inv abutment with the other. Having tilted the desk top at any desired. `angle,'the hand nut 21 may be tightened upon the clamping rod, drawing the braces 23 and the fixed supporting plates 18 into rigid relation with each other and in abutment with the oppositey ends of the spacer sleeve, thus securing the desk top in any' desired angular position.
It will here be lapparent that the means for angularly adjusting the desk top is independent ofthe forward and back adjustment of the position of the desk top, it being possi-ble thereby for the occupant of This the chair to draw the desk top toward him when seated and push it away'before arising without vdisturbing the angular position of the desk top or any books which may be resting upon it. It ,willv also be ynoted that the wooden slide barsl operate between metallic. brackets and metallic straps, which avoids the disagreeable noise frequently accompanying lthe movement of such slides when lconstructed of metal throughout. To further assure noiseless adjustments 0f the desk top, a pair of resilient .cushions"24a, preferably madeof rubber,
are secured to the upper surface of each of the'slide bars 14 and are adapted to receive the desk top when the latter is dropped to its lowermost position. The cushions 24l are also positioned relative to the front pair of guide vstraps 15, and on each side thereof, so that the cushions limit the forward and back movement of the slides and desk top by a noiseless abutment with the straps 15. It will be noted also that when disassembled, the braces 23 may be folded in close relation alongside of the `cleats 16 against the ldesk top, and also that the slides 14 may be fold-k ed against the desk top, thus facilitating packing in a minimum of space for shipment.
Referring toFig. 2, it will be seen that the back section 1 is joined to the seat section 4 by means illustrated in the cut-away portion and comprising a bolt v25 extendingy through the leg 2 into the structure lof the seat boardv and terminating` in a recess 26 adapted to receive a nut`27.` Each ofA the rear legs 2 and the front vleg 6 is attached to the seat `section by means `of the bolts 25 entering the seat and bottom boardsr ofthe seat section, in the manner illustrated. Thisconstruction permits the yready assembly ofthe back 'section and front ,leg
as a unit with the seat section by merely,V
inserting the bolts and tighteningv them in their nuts to secure the sections in vattachment and permitting their` separable packing in compact space for shipment. The standard also is removably attachedk to f the extended rportions 28v of the seat board and lbottom board of the seat section 4, by means of screws 29 supplemented by a ref movable angle brace 30,
Itv will here be apparent that the desk chair may be packed and shipped in separable units comprising back section, seat 'sec-- tion, standard, supportingbrackets and the desk top, all of which maybe assembled in a lcomplete lunit by themere connecting `of bolts and screws as described. i
