comnmnn SCHOOL DESK CHAIR.
Patented July 26-, 1921.
Application filed February 21, 1921. Serial No. 446,979.
To all whom it may cone-em Be it known that I, PHILO O. DEnnYsmRn, a citizen of the United States of America, residing at Chicago, Cook county, Illinois, have invented certain new and useful Imrovements in Combined School Desks and lhairs, of which the following is a full, clear, and exact description.
This invention relates to a combined desk and chair for use in schools, classrooms, lecture-rooms, etc., and its chief object is to provide a combined desk and chair in Wl'llCh the desk ortion can be adjustedvertically, horizontally and angularly, to make it convenient and comfortable to the occupant. Another object is to provide a chair-desk of the kind indicated, in which the desk portion is composed of two parts, one hinged to the other and normally occupying a generally horizontal position but capable of being swung upwardly to afford convenient and uiok ingress and egress of the occupant. A iurther ob'ect is to rovide a chair-desk of simple an substantlal construction, which can be manufactured and sold at a low price. To these and other ends the invention consists in the novel features hereinafter described.
One form of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the com plete device.
Fig. 2 is a rear view of the portion constituting the desk-top, and
Fig. 3 is a side view of the same.
Fi 4 is a side view of the upper end of the d esk-post or standard.
Fig. 5 is a pers ective view of the two parts of one of the inges used in the desk Figs. 6 and 7 are detail sectional views on lines 6-6 and 7-7, respectively, of Fig. 1.
Fig. 8 is a horizontal section of one of the hinges, on line 8-8 of Fi 1.
In the particular embo iment illustrated, the chair has its seat 10, Fig. 1, extended forwardly at the right to form a horizontal arm or su port 11, and the lower rung on the same side extends through the leg 2 to form a similar support 13. To these supports is secured a vertical post or standard 1n the form of a board 14 of suitable width and height, the lower end of which may be cut away atthe rear, as shown, to form a M foot 15. The standard may be secured to the supports 11, 1 3, in any convenient manner, as by means of screws or bolts 16, 17. In the upper portion of the standard are two relatively large apertures 18, 19, locatedside by side as shown in Fig. 4, the purpose and function of which will be described hereinafter.
In front of the chair and above the stand ard 14 is a substantial top 20, which overhangs the standard at the side thereof. and is adjustably mounted thereon by means of a pair of fiat clamping members 21, 22, preferably made of tough, spring wood, spaced apart the thickness of the standard by a s acing strip or batten 23 between the two.
n angle-iron bracket 24 on the outside of the clamp, and one or more shelf-brackets 25 tion of the bolts and apertures are such that .when the clamp is loosened by unscrewing the hand-nuts 29 the entire top assembly can be shifted forwardly or rearwardly, and up or down, and also may be tilted angularly, to accommodate the occupant of the chair, after which the whole can be firmly secured in adjusted position by tightening the nuts 29, as will be readily understood.
The desk or top is made in two parts or sections arranged edge to edge, the rear part 30 being pivotally connected to the relatively fixed front part 20 by means of a hinge at each end. In the preferred form each hinge comprises an elongated member 31 of heavy sheet metal, having a flange 32 which underlies the end edge of the top section 30 and is secured thereto by bolts or screws 33. The enlarged end of the hinge member overlaps the adjacent edge of the top 20 and has an arc-shaped slot 34. The other hinge mem ber 35, also made of heavy sheet metal, has a flange 36 which underlies and is secured to the edge of the top-section 20, as by means of bolts or screws 37. The enlarged and of the latter hinge member is provided with a stamped lug 38, which extends into the arcconnected by any suitable means, as a stout bolt 3 9, at the center of curvature ofthe areshapedslot'34.
The space below the chair seat may be boxed in, as indicated in Fig. 1, to accommo date a deep drawer 40.
It will be observed that the embodiment illustrated is simple in construction and'that its working parts are few and little liable to derangement; It can be made almost entirely of wood, without sacrifice of strength,
and the metal parts employed are well adapted to withstand the stresses to which they aresubjected in use.
It is to be understood that the invention is not limited to the construction herein specifica'l ly illustrated and described but be embodied in other forms without departure from its spirit;
I. In acombined chair and desk, in combination, a chair; a flat standard secured to the chair at the front and side thereof, having in its upper portion a pair oi apertures located side by side; a transversely extending horizontal top above the standard and in front of the chair; a pair ot flat clamping members depending from the underside of and secured to the top and embracing" the apertured upper portion of the standard; and a pair of clanr iiing bolts extending through the clamping members and the apertures in the standard, said apertures being larger than the bolts to permit hori zontal, vertical and angular adjustment of: the clamping members to vary the horizontal, vertical and angular positions of the top.
2. In a combined chair and desk, in (0111- bination, a chair; a flat standard secured to the chair at the front and side thereof, a horizontal top above the standard and in front of the chair, comprising a relatively fixed section and a movable section pivotally connected to the relatively fixed section at the rear edge thereof; a pair of flat clamp ing members depending from the relatively fixed section of the top and secured thereto, and embracing the upper portion ot the standard; and means for binding said elainping members upon the standard and permitting vertical, horizontal and angular adjustment of the said top.
