Description

July 22, 1952 F. J. HAVEL CHAIR WITH REMovABLE ARMREST vFiled sept. 15. 1948 Patented July 22, 1952 znpplicationseptember 15, 1948; SeriaIN'o. 1 49,410!! This invention' relates to a removable arm seat. The invention is applicable to all kinds of seats, including chairs, vdavenports, railway and other vehicle: seats, etc.

In the use of upholstered furniture in which the armrests are padded withv fel-t, etc., the earliest wear usually appears on the arm rests andfoften the entire seat'isidiscarded because of fthe unsightly appearance ci*V the chair .L arms orjrests, etc. 1

Aniobject ofthe-present invention is1to provide a structure-inwhichanupholstered'arm rest is rigidly secured to the-chair side railyas rnily as if fthe -partswere permanently' secured together While at the same-timeepermitting ready removalfof the arm-restfor-repairor for the substitution of anew armrest; Yetanother object is to provide a seat and. arm-rest structure in which: the arm rest canbe removed anextremely' brief period and anew or repaired'a'rm rest quickly substituted therefor, the upholstered arm rest having its covering electively concealed and the covering for the seat about the arm also being concealed and held in the space between the arm rest and the arm rail. Yet another object is to provide a wooden structure in which wood screws can be effectively used for the locking of the arm rest to the chair rail while providing an attractive structure and one in which the removable arm rest is locked as firmly to the chair rail as though it were permanently xed thereto. Still another object is to provide an arrangement whereby anattractive connection is made between a removable arm rest and a chair rail, all of the covering edges there-about being concealed while providing a simple means for rigidly anchoring the parts together in a releasable relation Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a single em.- bodiment, by the accompanying drawings, in Which- Fig. 1 is a perspective view of a chair equipped with a removable arm rest in accordance with my invention; Fig. 2, a transverse sectional view on an enlarged scale of the upholstered arm rest; Fig. 3, a vertical sectional detail view on an enlarged scale, the section being taken as indicated at line 3-3 of Fig. l; and Fig. 4, a side View in elevation and on an enlarged scale of a portion of the arm frame of the chair and the arm rest, a portion of the structure being shown in vertical section.

In the illustration given, I designates a seat illustrated'. as .zang` upholsteredlchaira The seat may. be-ofanyftype porvv structure. ,It-may bea railway seat, busseat, .davenport,1etc. Thespecio; seattillustrated is.; one whichmerelyk illu-s..- vtrates... the.. mannerf in which the.; invention may heusgd...

The rail Iliis providedin it'sgupper.. portion vwith a.,lon, gitudinally,extendingrecessorgroove 1.2.1v It is providedwith. the `usualifseat ,covering I 3,. the edges of which are ,drawn over-theupper portion of'jtherailill; as shownbestinFig, 3.l ,Y V.

j 1 Th'exarm. rest" I 4 'may'be oil any :suitableL con,- struction.- I' prefer topemploy' a 'rigidjbas'e inember t I 5c 'which mayjbe'. flaredi foutwardlyj sc as to provide a* relatively wide support for n the :felt lor other pad'dingmaterialv I6. A cover IT extends around the padding of the base I5 and may be secured to the bottom portion of the base. In the specic illustration given, the base I5 is formed of Wood and tacks I8 are employed for securing the covering I1 to the bottom portion of the block or base I5. The base I5 is provided with a longitudinally extending slot Which receives the anchor member or block I9. I prefer to secure the anchor I5 within the recess 1n the block I5 by glue but any suitable means may be employed for this purpose. With the structure, the anchor I9 extends between the edges of the covering material I1 and depends there-below.

As shown more clearly in Fig. 4, the depending anchor I9 is inserted within the recess I2 of the chair rail II.v In order to provide an attractive joint between the parts', I prefer to employ the welts 20 on either side of the anchor I9 withvthe roll of the Welt extending along the line of junction between the arm rest I4 and the chair rail II.

I have discovered that an extremely eiective anchor is accomplished by passing a Wood screw 2I through the chair rail II and into the anchor I9. The screw holds the nat block or anchor I9 tightly against a wall of the rail II so that the parts are held together with great rigidity. I prefer, also, to provide a washer 22 formed in the shape illustrated in Fig. 3 which not only enhances the appearance of the connection but also provides a spring about the screw tending to hold it xedly in position. At the same time, the stress is distributed by the washer 22 over a relatively wide area of the covering material I3.

In the specific illustration given, two screws 3 and washers are employed on each side of the chair and the location of the washers near the point of junction renders them inconspicuous and not unattractive in appearance.

When the arm rest has become unattractive by reason of long use, the screws 2 I can be quickly removed and a new upholstered arm rest l 4 substituted for the one'removed. The operation requires but a moment' and the new rest is'secured as rigidly to the seat as though all the seat were of new construction.

While in the foregoing specication, I Vhave set forth a single structure in considerable detail for the purpose of illustrating one embodiment of the invention, it will be understood that the details of such structure may be varied widely by those skilled in the art without departing from.v

the spirit of my invention.

I claim:

I 1. In combination with a seat equipped with an arm rail having a longitudinal groove in its upper portion,-an arm rest consisting of a rigid base provided with a groove adapted to be aligned with the groovein said' arm rail, a rigid anchor extending into the -groove of said base and rigidly Vsecured therein by glue,'said anchor having a vagainst'thelarm rail'at one side of said arm rail 2. In combination with a seat equipped with a wooden arm rail having a longitudinal groove in its upper portion, an arm rest consisting of a rigid base which is generally semicircular in cross-section and provided With a flat-topped surface, lsaid base having a groove extending upwardly therein, padding on the flat portionof vrsaidbase, a covering extending about said padding and'base and securedtothe bottom of said base, a rigid anchor extending into the groove of said base and rigidly secured therein, saidv anchor having a depending rib received Within thegroove of said rail, a covering about said arm rail and having the end portions extending inwardly into the space between said arm rail and said base, and a screw Vextending Vthrough said arm rail and into said anchor rib to clamp said anchor rib tightly against one Wall i of said arm rail at one sfide of the groove therein.
