FOLDING CHAIR.
Specification of Letters Patent.
Patented Feb. 19, 1907.
Application filed April 26, 1906. Serial No. 313,850.
T0 at whom it may concern.-
Be it known that I, lVILLIAM GYMER, a citizen of the United States, residing at Boulder Creek, in the county of Santa Cruz and State of California, have invented a new and useful Folding Chair, of which the following is a specification.
This invention relates to folding or collapsible chairs; and its object is to provide a device of this character which may be folded into a compact bundle and which can be quickly opened, so as to constitute a rigid chair.
The invention consists of a standard having sleeves mounted on it adjacent its ends and from which radiate arms which are so connected to the ends of the standard that when the sleeves are moved toward each other the arms will fold against the standard, and vice versa. Means are provided for positively actuating the sleeves simultaneously. and for automatically securing them after they have been adjusted to open the chair. Supplemental supports are connected to certain of the arms to reinforce the standard, and a back and seat are detachably mounted on the chair.
The invention also consists of certain other novel features of construction and combinations of parts which will be hereinafter more fully described, and pointed out in the claims.
In the accompanying drawings is shown the preferred form of the invention.
In said drawings, Figure 1 is a front elevation of the chair. Fig. 2 is a side elevation partly in section. Fig. 3 is a plan view of tl1e top of the chair with the back in section. Fig. 4 is a view, partly in section, of the chair collapsed. Fig. 5 is an enlarged section through the rack actuating and locking mechanism, said section being taken on the line a: as, Fig. 1. Fig. 6 is an enlarged section through the handle and standard, taken on the line 'y y, Fig. 2. Fig. 7 is an enlarged section through the standard and sleeveguide, said section being taken on the line 2 2, Fig. 1.
Referring to the figures by numerals of ref erence, 1 is a standard having an angular flange 2 at its upper end and a similar flange 3 at its lower end. Slidably mounted on the standard near its ends are upper and lower sleeves 4 and 5, respectively, each sleeve having ears 6 thereon. Pivotally connected to the ears of the upper sleeve are arms 7, which radiate from the sleeve and have depending toes 8 adjacent their pivots, which are adapted when the arms assume horizontal positions to contact with the sleeve. Each of these arms has a rod 9 pivoted to it ata point between its ends, said rods being pivotally connected to the upper flange 2.
The arms 7 are adapted to support a seat 10, formed with a plurality of parallel slats 11, flexibly connected by means of straps 12, and pivotally connected to the end slats are supporting-straps 13, adapted to be swung into position under all of the slats, so as to hold them in proper relation when they are disposed upon the arms 7. Some of the arms 7 terminate in sleeves 14, adapted to receive uprights 15, to the end ones of which are pivoted the ends of a top slat 16, connected by means of flexible straps 17 to slats 18, one of which is preferably pivotally connected to the intermediate upright 15. The end uprights are preferably locked within their sleeves by means of spring-catches 19, and all of the uprights and slats connected thereto constitute a detachable back for the chair.
Pivot-ally connected to the ears 6 of the lower sleeve 5 are-base-strips 20, which radiate froin the sleeve and preferably terminate in feet 21, adapted to contact with the ground. Each of these strips has a toe 22 adjacent its pivot and adapted to swing against the sleeve to limit the upward swinging movement of the strips. Rods 23 are also connected to the strips 20 at points between the ends thereof, and the inner ends of these rods are pivotally connected to the lower flange 3. '1 he arms 7, extending to the rear corners of the seat 10, have supplemental supports 24. pivoted to them and extending downward and pivoted to the corresponding strips 20. 'lhese supplemental supports are parallel with the standard 1 and substantially equal in length thereto.
When the seat is set up or open and with the parts in positions described, the same can be very quickly collapsed by first lifting the seat from the arms 7, swinging the supporting-strips 13 into position parallel with the slats 11, and then rolling the slats into a compact bundle. The back is then removed by disconnecting the catches 19 from the sleeves 14, after which the uprights 15 can be swung into position parallel with the slats 16 and 18 and the back can then also be rolled into a compact bundle. Levers 32 are now pressed together, so as to retract the lockingpins from engagement with the racks 26, and gear 27 is rotated by means of a crank, so as to draw the racks together and cause a corresponding movement of the sleeves 3 and 4. As the arms 7 and strips 20 are connected to the flanges 2 and 3 by means of rods 9 and 23, this sliding movement of the sleeves will result in the arm 7 and strips 20 folding inward against and parallel with the standard 1, and the supplemental supports 24 will be drawn inward toward said standards and rest close to it. During the operation of rotating the gear the handle 34 can be grasped to facilitate said operation. It is to be understood that the handle 37 is grasped while the chair is being folded in the manner above described, so that the hand will not be in the way of any of the sliding or folding parts. After the parts have been completely folded the spring-pressed plunger 38 of the handle is disengaged from the standard and said handle is folded into position parallel with the standard. The arm 34 is then slid longitudinally upon the strip 33 and grip is folded thereagainst, There are therefore no projecting parts upon the collapsible support and a comp act bundle is produced which can be conveniently carried from place to place. To set up or open the chair, the operation above described is reversed, and as soon as the arrrs and its strips assume their proper position the racks will be automatically locked by the spring-pressed locking-pins 30. The seat and the back can then be placed in proper position and the device is ready for use.
It will be noted that the two sleeves 4 and 5 have inwardly-extending lugs 40, which travel in a slot 41 in standard 1, so as to prevent the sleeves from turning. This construction is shown in detail in 7.
If preferred, flexible bracing-strips 42, formed of strong cord, light chains, or other devices, may be connected to the ends of the sftrips 7 and 20, as shown by dotted lines in The preferred form of the invention has been set forth in the foregoing description; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrilicing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the invention.
