FOLDING CHAIR AND ALIGNER THEREFOR Filed Sept. 17, 1936 2 Sheets-Shaet 2 Patented Sept. 26, 1939 UNITED STATE PATENT OFFIQE Roscoe G. Geller, Owego, N. Y., assignor to Stakmore (3a., Inc., New York, N. Y., a corporation of New York Application September 17, 1936, Serial No. 101,304
This invention relates to folding chairs and more particularly to a device for holding a plurality of said chairs when arranged in a row for occupancy in locked aligned relationship.
It is well known that folding chairs when placed in rows for use soon become disarranged by virtue of the movements of the people occupying the same either while seated or during ingress or egress between the rows thereof. In some cases a chair or chairs are even bodily removed from a row and carried to another place which obviously destroys the aligned relationship of the same. In any case where folding chairs are utilized in large numbers considerable confusion, annoyance, inconvenience, noise and loss in time results unless some expedient is resorted to for holding the chairs in place.
To accomplish this desired result various methods have been utilized to hold the chairs together, such as by clamping or fastening a board to the underside of the seats, or by clamping or fastening a rod or bar directly to the legs of the chairs. The employment of such expedients involves the'expenditure of great amount of time and labor especially when it is necessary to lay out a large number of chairs, both when assembling the chairs in rows and when dismantling the same, and has proven quite expensive.
It is therefore an object of this invention to 'provide a readily attachable and demountable rigid cross bar adapted to engage certain selected pivotal connections of folding chairs in such a manner as to look a selected number of chairs,
I aligned side by side, into a single unitary row.
Another object is to provide a means for aligning any selected number of folding chairs, which means is itself locked in place by similar portions of the chairs in their unfolded position.
Another object of this invention relates to the provision of hook elements on the aligner bar which are adapted to engage said pivotal connections or like members and to so suspend the aligner bar therefrom as to provide a locking engagement between the aligner bar and the seats of the chairs.
A further object of the invention relates to the simplified quick and efiicien't manner of applying the aligner bar to a row of chairs and in removing the same therefrom without the use of tools, separable fastening elements or other mechanical appurtenances.
These and numerous other objects and advantages will be more apparent from the following detailed description when considered in connection with the accompanying drawings, wherein:
Fig. 1 shows in front elevation a group of folding chairs with the aligner bar in applied position thereon.
Fig. 2 shows in perspective one of the folding chairs shown in Fig. 1 and the mounting of the aligner bar with relation to the seat of the chair.
Fig. 3 shows a similar view in perspective of the mounting of the aligner bar on a folding chair of a different type. V
Fig. 4 shows in end elevation one end of the aligner bar and the hook construction.
Referring now to the drawings more in detail wherein like numerals have been employed to designate similar parts, Fig. 1 shows four folding chairs is arranged side by side to constitute what will hereinafter be referred to as a row. Each of the chairs it is of a conventional and well known design and comprises a pair of front legs i i made of wood and having a fiat forward edge or face i2, and a pair of rear legs l3 constituting the arms of a metallic U-shaped rod M, the up per free ends of the legs i3 being pivotally connected to the inside faces of thefront legs ii as at 25. Between the pivotal connections i5 and the bottoms of the front legs I i is a seat it which seat is pivotally mounted on the scat rod ii connecting the seat it to the front legs. A detailed description of the chairs is not essential for a clear understanding of the invention and these particular chairs are merely shown for the purpose of illustrating one practical application of the invention. It will be observed from both Figs. 1 and 2 that the sides of the seat it are spaced a substantial distance as at i8 from the inside faces of the front legs H.
Arranged to extend traversely across the underside of the chair seats it of the row of chairs it is an aligner bar 29 which may be made of wood or metal of any desired cross-sectional shape. Preferably the aligner bar 2% is formed of a wood rail rectangular in cross-section for a purpose to be hereinafter described, the rail being of such a length to extend completely across the row of chairs as clearly shown in Fig. 1. On one side of the cross bar there are securely attached four pairs of identical hooks 2|. Each hook 2i comprises a flat shank portion 22, see Fig. 4, the lower end of which terminates in a forwardly projecting flange 23 adapted to fit the lower edge 28a of the cross bar, the flat side of the shank 22 abutting the inside face 2% of said cross bar.
The length of the shank 22 is substantially equal to the width of the aligner bar 20 and terminates at its upper end in a hook 24 oppositely directed with respect to the flange 23, the terminus 25 of the hook being preferably parallel to the shank 22, and with the end a substantial distance below the top of the hook whereby to provide an engaging portion of substantial depth. Rivets 26 securely connect the hooks 2| to the aligner bar 20, the flanges 23 functioning to prevent turning of the hooks.
The hooks 2| are arranged in pairs on the aligner bar20,the hooks in each pair being spaced apart a distance substantially equal to distance between the vertical parallel center planes of the spaces IS. The adjacent hooks 2| of adjacent pairs are spaced apart a sullicient distance to effect the normal spaced apart relation between the chairs l0.
Thus, with the chairs l0 arranged in a row and properly spaced, the aligner bar 20 is easily and quickly applied thereto by the simple expedient of positioning the pair of hooks 2| in the spaces 8 for hooking engagement with the hinge pins II. When so suspended the inside flat face of the aligner bar 20 will lie on the front flat face l2 of the front legs I I. With the hook portions 24 being made a predetermined length, the upper edge 200 of the aligner bar 20 is in position, when the cross bar is applied, as to be pressure contacted by the underside of the seats I6 to effect a positive locking engagement of the aligner bar 20 to the row of chairs.
It will thus be apparent that the aligner bar 20 acts to positively hold the chairs II) in their proper alignment and prevents accidental removal of a chair from the row or disarrangement of the entire row. It is also obvious that by virtue of the extreme simplicity of the aligner bar 20 and the manner of attaching and demounting the same, a great saving in time and labor is achieved in assembling the chairs in groups of rows. While the aligner bar 20 has been shown of a length to connect together four folding chairs in a group or unit it is to be understood that the same may be made of any desired length for any desired number of chairs. In some cases suitable connecting means may be utilized for connecting together adjacent ends of lengths of cross bars to provide a single cross bar of great length.
Fig. 3 illustrates the type of chair shown in U. S. Patent No. 1,873,763 granted August 23, 1932, to Albert S. Kux, and assigned to Stakmore Co., Inc., in which a telescopic connection is provided between the front part of the seat and the upper parts of the rear legs 32, to permit folding of the chair. The chair 3!] is also provided with front legs 3|, and these front legs 3| are pivoted to the rear legs 32 at a point intermediate their ends, as indicated at 33. The construction is such that the rear legs are spaced from the front legs at their pivotal connection 33 a suitable distance, as indicated at 34. In assembling together such a group of chairs 3U, utilizing the same form of aligner bar 20, the hooks 2| are slipped into the spaces 34 for engagement with the hinge pivots 33. When so suspended the aligner bar 20 lies against the forward edges of the front legs 3|, and is locked in place by the upper part of the rear legs 32 when the chair is in its unfolded position.
While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of the invention.
