Referring more in detail to the drawings:

As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for. the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate detailed structure.

The present invention relates to ganging structures for chairs, preferably chairs adapted to be stacked for storage. The reference numerals l and 2 designate similar chairswhich may be selectively ganged in side-byside relation. The

chairs

1 and 2 have seats 3, backs 4 and front and

rear legs

5 and 6 on each side of the seat 3 and depending relative thereto. It is preferred that the front and

rear legs

5 and 6 be inclined relative to each other and diverge downwardly.

In the structure illustrated the chair structure has a unitary structure with seat member and

back member

3 and 4 respectively mounted on a frame structure (not shown). The leg members Sand 6 are secured to and depend from the frame structure for supporting the seat and back members. The front and

back legs

5 and 6 on each side are inclined outwardly and downwardly forming an inverted V-shape and are spaced outwardly of the sides of the seat member2. Each of the legs 5- and 6 have a glide 7 secured thereto at the bottom of each leg. Ganging clips or leg connectors 8 are movably mounted on afront leg 5 and back leg 6 of the chair 1 and are movable from a ganging position to a retracted position. The connectors 8 are mounted beneath the seat member 3' and have means associated therewith for preventing their movement'longitudinally along the respective legs Sand 6 and are operable to grippingly retain an adjacent chair 1 for holding same in line.

The connectors 8 are each pivotally mounted on a

leg

5 or 6 and asillustrated on one side of the chair 1 with each having a bore 9 through one end thereof and having a clip or open portion 10 adjacent the other end of the connector 8. The connector 8 as illustrated is comprised of a sleevemember l1 and half sleeve member 12 connected by a webmember 13 extending therebetween and having opposed flange members 14 preferably integral therewith on opposite sides of the web 13,

I tally.

sleeve 11 and half sleeve 12. The bore 9' extends through the flanges 14 and the sleeve 11 and rotatably receives a portion of a

respective leg

5 or 6 therethrough. In the illustrated structure, the clip portion 10 hasachannel like opening extending through the half sleeve 12 and the flanges 14 with a longitudinal axis generally parallel to the axis of the bore 9. The clip portion 10 as illustrated is defined by an interior surface 15 which is generally U-shaped or semi-circular transverse to the axis of the clip portion 10.

In the structure shown in FIG. 1 to FIG. 5 inclusive, the connectors 8 provide space between the side-byside ganged

chairs

1 and 2. The space allows chair structure such as arm rests and the like to be added to the.'chairs and still permit them to be ganged horizon- In the illustrated structure, as best seen in FIG. 2 and FIG. 5, a leg 6 extends through the bore 9 having the connector 8 suitably mounted thereon. The connectors 8 and the

legs

5 and 6 are provided with cooperating abutment portions for limiting the movement therebewith the connectors 8 in place. Preferably, the stop member 23 is secured to a

leg

5 or 6 so as to be hidden from view pointing generally toward the respective leg .5 or 6 o'n'the opposite side of the chair 1. The abutment or engagement between the stop member 23 and the

end surfaces

17 and 18 and the side surfaces 19 and limits swinging movement and longitudinal movement, respectively, of the connectors 8 relative to the

legs

5 and 6.

member'23 whereby the protuberances will retain the connector 8 in a selected position by obstructing or frictionally resisting relative movement from the selected position. In the illustrated structure, the connec- -tor 8 is movable from a ganging position to a retracted position and is held in one of the positions by a'protuberance 25, the ganged position being with the connector 8 pointing outwardly and away from the chair 1 and the retracted position being with the connector 8 pointing generally towardthe

other leg

5 or 6 on the same side of the chair 1 so as to be out of the way when desired. In the ganging position the clip portions 10 face generally toward oneanother. The retracted position is best seen in chair 2 inFlG. 1 and the ganging position is best seen in chair 1 in FIG. 1..

Where the chair structure permits-close ganging, the

. connectors 8 are of a short lengthallowing the close ganging. FIG. 6 and FIG. 7 illustrate a connector 8 in a shortened form which permits the close ganging. The

shortened form has a reduced spacing between the clip portion 10. and-the borev 9 and as illustrated they are side-by-side with the web 13 absent. Different spacings between'the clip portion 10 and bore 9 are used to accommodate particular chair structures and spacing requirements. Y

Chairs

1 and 2 are positioned in side-by-

siderelation having legs

5 and 6 on one side of chair l'adjacent to corresponding

legs

5 and 6 on one side of chair 2. The connectors 8 are moved to a ganging position with the connectors 8 moving in a plane generally normal to the axis of the

respective leg

5 or 6 and by raising the side of the chair having the connectors 8 mounted thereon and then sliding the connectors 8 downwardly on the.

adjacent legs Sand 6, the

adjacent chairs

1 and 2 are secured in ganged relation. Todisconnect the

chairs

1 and 2, the reverse of the ganging procedure is done. The ends 17. and 18 of the slot 16 limit the amount of swinging movement of the connectors 8 whereby with I the stop members 23 in engagement with the'surfaces 18 the connectors .8 securely grip the

adjacent legs

5 and 6, within the respective vclip portions 10 securing the

chairs

1 and 2 together in line.

FIGS. 8, 9,10 and 11 illustrate a modified form of a movable leg connector 31 to be mounted on legs of chairs which are preferably adapted to be stacked for storage. The numerals l and2-designate similar" chairs which may be; ganged in side-by-side relation and have seats 3 and backs 4 with a front leg 5 and a back leg 6 on each side of the seat 3 and depending therefrom. A leg connector 31 is movably mounted on a front leg 5 and a back leg .6 for selectively grippingly retaining an adjacent leg of a chair in side-by-side relation thereto and holding said chairs in line. The connectors 31 are movable relative to the leg on which they are mounted from a ganging position to a retracted position with the connectors 31 and the

respective legs

5 or 6 having cooperative abutment portions to limit the relative move ment.

In the illustrated structure, the connectors 31 have a pair of

fingers

33 and 34 at each end thereof, The fingers 34 are opposed and spaced apart for receiving therebetween a

leg

5 or 6. A securing device such as a rivet or the like and as illustrated, a bolt extends through apertures (not shown) through'the fingers 34 and the

legs

5 and 6 movably or swingably mounting the connectors 31 on the

legs

5 and 6 preferably on one side of the chair. A nut 37 is threaded on the bolt to secure the assembly in place. An intermediate body portion 38 extends between the pairs of

fingers

33 and 34 connecting same together and as illustrated, the body portion 38 is a channelmember with an open side having upstanding side flanges 39 with a bight portion '40 The fingers 33 are opposed and spaced apart defining a generally U-shaped opening 44 therebetween. The bight 40 has an edge 43 adjacent the fingers 33 that is arcuate and is used for a purpose to be later described. Preferably, the fingers 33 are arcuate curving toward one another whereby the opening 44 therebetween is decreased in .width at a point outwardly of the edge 43 to present an interference to the leg being installed therein or'removed therefrom. The size of the opening increases outwardly of the narrow portion due to the arcuate shape of the fingers 33 thereby providing an enlarged lead-in area to facilitate installation of a leg.

The narrow part of the opening 44 is preferably smaller thanthe diameter of the

adjacent leg

5 or 6 while the portion adjacent the edge 43 is approximately the same width as the diameter of the

adjacent leg

5 or 6.

The connectors 31 are swung to a ganging position in which they are generally normal to the

respective leg

5 or 6 with the edge 41 in abutting engagement with the

respective leg

5 or 6 having the opening 44 between the fingers 33 pointing outwardly and away from the side of the chair 1. The chair 2 is moved to a side-by-side in-line relation with the first chair 1 whereby adjacent legs and 6 are forceably urged between The fingers 33, which move elastically away from one another,

through the decreased size opening 44 and into abutment withthe edge 43 of the respective connector 31 whereby the adjacent leg is grippingly held between the fingers 33 holding the adjacent chairs .in line. The narrow spacing between the fingers 33 preferably is less than the, diameter of the

adjacent leg

5 or 6 to grippingly retain same therebetween and prevent accidental disengagement. When not in use, the connectors 31 are swung upwardly whereby the fingers 33 are in gripping engagement with the

respective leg

5 or 6 on which they are mounted, as best seen in FIG. 9, and the bight 40 is in abutting engagement with the

leg

5 or 6 limiting the amount of upward swinging movement of the connector 31 whereby the connectors31 are maintained in the retracted position and out of the way. To disconnect adjacent chairs, the reverse of the connecting procedure is done. The swinging movement of the connectors 31 is in a plane generally parallel to the longitudinal axis of the

respective legs

5 and 6.

In the illustrated structure in FIGS. 8, 9, and 11, the

legs

5 and 6 on each side of the chairs form an inverted V, are spaced outwardly of the sides of the seat member 2 and are adapted for vertical stacking of the chairs whereby'one of the chairs will be positioned on a lower chair. The connectors 31 when in the retracted position prevent interference with the legs of the vertically stacked chairs as is normally found in present chair ganging structures. It is to be noted that the connectors 31 provide for a slight amount of relative movement between ganged chairs while holding same in firm ganged relation allowing for the ganged chairs to be placed on floors having a mildly irregular surface and still having 'a stable ganged structure.

It is to be understood that while We have illustrated and described certain forms of our invention it is not to be limited to the specific forms illustrated and described herein.
