NESTED 'ARMCHAIR Filed Oct. 16, 19s? Sheet 3 of s INVENTOR 04 W0 L. ROWLAND ATTORNEYS United States Patent US. Cl. 297-239 13 Claims ABSTRACT OF THE DISCLOSURE A compactly stacking armchair is provided of the type having a frame that has at each side of the chair a rear leg portion, a bottom rail portion, a front leg portion and a side rail portion above and inset from the bottom rail portion, the frame having at least one cross member extending across from one side to the other, and a seat and back bridging from one side to the other. The armchair is characterized by a metal arm frame on each side of the chair having a generally horizontal upper portion above and generally parallel to the side rail and outset therefrom beyond the bottom rail, extending and outset from and secured to the rear leg portion. A generally vertical portion extends from the forward end of the horizontal upper portion to ground level, a short bottom horizontal portion connects the vertical'portion to the bottom rail portion, and an arm rest is supported by the generally horizontal portion of the arm frame.
This invention relates to a compactly stacking armchair. r
The present invention provides for an armchair which is otherwise of the same basic construction as the very compactly stacking chairs shown in my US. Patents Re. 26,071, 3,275,371, 3,278,227, and Des. 202,775. Like the chairs of those inventions, the armchair is compactly stackable, and has a light, airy appearance. It is also comfortable, and it has the additional comfort of a pair of arms.
It is unusual to provide an armchair which is so compactly stackable, and the structure by which the compactly stackable chair of my above-mentioned patents can be modified to make it an armchair is unique. It is particularly desirable to have the two types of chair (armchair and armless chair) be substantially identical except for the arms, so that production costs are saved, and by this invention it is not necessary to re-design the chair in order to provide the arms. Thus, it becomes compatible with and stackable with armless chairs of the same general design and can be made by exactly the same processes by simply adding the arms and the supporting structure for the arms.
It is important in providing compactly stackable arm chairs to prevent binding between the successive chairs, for binding is liable to occur in several places, as will be explained below. This problem has been solved in a simple and practical structure, which enables full use of a regular armless chair with the addition of parts in a few simple operations to convert it into the armchair of this invention.
Other advantages and objects of the invention will appear from the following description of a preferred embodiment.

FIG. 9 is a view in front elevation of ing the principles of the invention. I
As stated earlier, the chair of this invention is basically that shown in patents, Re. 26,071, 3,275,371, 3,278,227, and Des. 202,775. Like them, there is a seat 20, a back 21, and a frame having a rear leg portion 22, 23, bottom rails 24, 25, front legs 26, 27, and side rails 28, 29 which are joined to the rear legs 22, 23. There are also cross support members 30 and 31 joining the two sides of the chair, which are mirror images of each other. Each rear leg 22, 23 has a reinforcing fin structure 32, 33 extending out laterally and extending both above and below the level of the side rails 28, 29. In the preferred structure shown, the seat 20 is supported by the side rails 28, 29, and the back 21 is supported by the rear legs 22 and 23.
In the present invention, there is an arm support frame 40 and an arm rest 41 which is secured to and supported by the arm support frame 40.
The arm support frame 40 comprises a metal rod preferably of substantially the same thickness and characteristics as that from which the main frame is made, which is bent to provide a generally horizontal arm rest support portion 42, a generally vertical pillar '43 extending down to ground level and a short crosswise extending horizontal portion 44, which is welded to the bottom rail 24, 25 and which serves to offset the pillar 43 and support portion 42 from the bottom rails 24, 25. At the rear end of the horizontal portion 42 is a curved portion 48, extending in to the rear leg 22, 23 and welded to it. Preferably welded to this horizontal portion is also a metal horizontal support plate '45 which may have a pair of openings 46 and 47.
The arm rest 41 itself may be made from plastic, wood, or other suitable material and is shaped preferably as shown in the drawings. It is provided on its lower surface 50 with a recess 51 for receiving the support plate. As shown in FIG. 5, the arm rest 41 may be secured to the plate 45 by a pair of rivets 52, 53 or screws indicated in FIG. 3 also, or, as shown in FIG. 6, the attachment may be made by heat-staking the plastic of the arm rest 41 into the openings 46 and 47.
It is important that the vertical pillar 43 be spaced out from the seats side rail 28, 29, leaving space so that stacking can be accomplished. It is advisable to have the a chair embodyinner edge of this pillar 43 substantially outboard of the outer edge 55 of the fin 32, '33 to help to prevent binding in stacking.
It is also important that the inner edge 56 of the arm 41 be canted outwardly to help feed in the pillar 43 of the next chair on the stack. The space is important in preventing binding between the arm pillar 43 and the inner edge 56 of the arm 41. The arm rest 41 may have substantially parallel edges 56, 57 for most of its length, although the edges may converge toward the rear and may turn upwardly at a rear portion 58 both as a design feature and for comfort. The outward divergence is noticeable in FIG. 8, and it will be seen there that the arm rest 41 itself may partly overlie the horizontal portion 42 of the arm support frame 40, but as it approaches the outer edge, the canting diverts it entirely away from it.
Thus, it will be seen that when the arm rest 41 is attached to the arm rest support frame '40, the two form a unit which is simply added to the chair already made in accordance with the procedure explained in the patents referred to. The only thing necessary to complete the armchair is to weld the end 48 to the rear leg 22 or 23 and the end of the short portion 44 to the bottom rail 24 or 25. The two arrnsupport frames 40 and the arm rests 41 are mirror images of each other, rather than identical, but only these two sub-assemblies are required to complete the armchair assembly.
That the chair is compactly stackable is shown in FIG. 2 as well as in FIG. 7. The lowermost chair is set in any desired position and then an upper chair is placed on it coming down and from the front. The chair is stacked with the pillar lying within the arm, and therefore the canting helps in the stacking. Also, the stacking results in the upper chair being slightly forward of the lower chair, so that in order to get a high stack, it is desirable to support the bottom chair at an angle as shown in Patent Re. 26,071, as upon a dolly, such as shown in U.S. Patent 3,338,591.
To those skilled in the art to which this invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. The disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
