CHAIR.
Application filed April 7,
This invention has-reference to a chair or stool, in which the seat is adjustable to be secured on the tloor portion at different heights from or above the floor.
The main object of this invention is to provide a device of this character that can be constructed out of very simple and cheap parts, with very little machine work, or hand labor to construct, and in which the adjustment elements are simple and secure, and will function with ease and facility, and yet will securely and reliably retain the adjusted members in all positions without liability to derangement.
In the accompanying drawing illustrating one embodiment of my invention Figure 1 is a perspective view of the chair.
Fig. 2 shows the bail detached.
Fig. 3 is a section on the line 33 of Fig. 1.
The device as shown comprises two essential members, the floor member and the seat member. The seat member is shown as formed of a seat proper 2, that may be about square, as shown, or more or less round. A
" pair of bars 3 and 4t extend down from the two front corner port-ions of the seat 2; and a pair of inclined bars 0 and 6 are connected to the lower parts of the bars 3 and 4; and project upwardly and are secured to the two rear corner portions of the seat. As shown these inclined bars 5 and 6 are extended above and beyond the seat 2, as at 7 and 8, and are provided with a cross piece 9, to form a back rest for the user. This piece 9 is shown as hinged bet-ween the bars 7 and 8, to swing on an axis preferably just below its center of gravity, so that it will freely swing to accommodate itself to the user. At the bottom a cross bar 10 is secured to the upright bars 3 and 4, thus forming a unitary seat member that is rigid and strong.
The floor member is shown as composed of three bars on each side, that are connected by cross bars. On one side an inclined bar 12 is supported by an upright bar 13, secured to- 'ether at the top, and which are connected by a cross bar 14L at the bottom, as shown. On the other side a similar side member is shown composed of an inclined bar 15, an upright bar 16, and a cross bar 17, secured together, and substantially identical with the said side members 12-1314l. These two side members are cross connected bycross bars 18 and 19 at the rear, at the upper and lower parts of the upright bars 13 and 16, as shown; and at the lower ends of the bottom 1927. Serial No. 181,838.
by sliding the seatmember on the engaging bars of the floor member, the seat will be raised and lowered, and still remain horizontal.
Means are provided to secure the two sliding members together, in various positions of adj ustmcnt of the seat from the floor. I provlde a ball that is pivoted or hinged to the sliding bars of one member,'such as the floor member, that will swing and engage with difterent portions of the bars respectively of the other member. As shown I arrange a bail 20, bent at each end as at 21 and 22, and apertured to receive screws 23, that screw into the bars 12 and 15 of the floor member. The bars 5 and 6 of the seat member are each provided with notches 24 and 25, respectively,
into which the bail 20 can swing at the end portions, as shown, and thereby lock these bars together. ()n swinging the bail upwards to release from the notches, that are arranged parallel, the seat bars 5 and 6, can slide up or down on the engaging bars 12 and 15, and the bail swun down again to engage another pair of notches, and thus lock the seat member in adjusted position.
A pair of guide bands or loops 26 are securedto the bars 12 and 15 at the upper ends of the engaging portions of the bars; and a similar pair of loops 27 are secured to the bars 5 and 6 at the lower parts of these bars; that will insure these bars remaining in engagement at all times, and to slide freely when released by the bail.
lrVhat I claim is:
In a chair, a seat member comprising a seat, a pair of upright bars extending down one from each front corner of the seatand secured thereto, a pair of inclined bars secured at their middle portion to the rear of the seat and extending down to and secured to the lower ends of said upright bars and also extendin upwardly from the seat a considerable istance with aback rest connected between the upper end of these bars, a cross bar secured between the lower ends of said upright bars, a floor member comprising a pair of upright bars, a cross bar connecting the lower ends of the latter bars, a
pair of inclined bars connected at their upper ends to the said floor upright bars, a cross bar connecting the lower ends of said floor member inclined bars, a lower cross bar on each side connecting the said inclined and upright floor bars, said inclined seat bars being slidable upon said inclined floor member bars, cleats secured to the inclined seat bars bent around the floor member inclined bars form- 10 ing guides for said movement, said seatin clined bars being each provided with a series of notches, said inclined floor member bars having a cross bail hinged thereto and arranged to engage the notches of the inclined seat bars respectively, to adjustably secure the seat member in different positions on the floor member.
