Description

Feb. 22, 1966 H. J. KAUFMAN STACKING CHAIR WITH ARMS ATTORNEYS.
Filed Dec. 13, 1963 United States Patent 3,236,559 STACKING CHAIR WITH ARMS Hans J. Kaufman, 14 Dunlop Road, Huntington, Long Island, N.Y. Filed Dec. 13, 1963, Ser. No. 330,306 4 Claims. (Cl. 297-239) This invention relates to chairs that stack upon one another when not in use and when it is desired to store the chairs in a smaller floor space.
It is an object of the invention to provide an improved stackable chair which is of attractive appearance and which is not made with the usual awkward construction that results from concessions in design that are used to obtain the stacking feature for the chair.
Another object is to provide a sta-ckable chair having arms and with the arms a part of the chair that connects with the back as in a captains chair.
The chair of this invention obtains greater comfort for an occupant by having arms located outside of the side frames that nest when the chairs are stacked. Thus, arm supports for the occupant are located further apart than in chairs of the prior art where the only arm rests have been the tops of the side frames that nest with one another and where greater width for the arm-supporting surfaces would require that the entire frame of the chair be made wider.
Another advantage of the construction of this invention is the improved strength provided by the geometry of the parts of the frame and their relation to one another.
Other objects, features and advantages of the invention will appear or be pointed out as the description proceeds.
In the drawing, forming a part hereof, in which like reference characters indicate corresponding parts in all the views:
FIGURE 1 is a side elevation of a chair made in accordance with this invention;
FIGURE 2 is a top plan view of the chair shown in FIGURE 1;
FIGURE 3 is a front view of the chair shown in FIG- URES 1 and 2;
FIGURE 4 is a side view of the chair shown in the other figures, stacked with a like chair;
FIGURE 5 is an enlarged fragmentary view partly in section on the line 5-5 of FIGURE 4; and
FIGURE 6 is an isometric view, on a reduced scale, showing a modified form of the invention.
The chair of this invention includes side frames 11 and 12, each of which includes a front leg 14 and a back leg 16. These legs 14 and 16 converge toward one another and are rigidly connected together at an upper end 18 of the side frame at a vertex as shown in FIGS. 1 and 4.
The front legs 14 are connected together by a transverse frame element 20 (FIGURE 3) which has its ends connected to the front legs 14. The transverse frame element 20 is of substantial vertical height andhas its end faces in contact with the front legs 14 over a substantial vertical area to provide a strong rigid connection between the front legs 14. A similar transverse frame element 22 (FIGURES 1 and 2) connects the back legs 16.
The chair has a seat 26 which is preferably supported from the transverse frame elements 20 and 22, but which may be immediately above the transverse frame elements 20 and 22 and connected directly to the legs 14 and 16 with spacers so that the legs will not rub against the seat.
This seat 26, and strips 44 whether connected to the transverse frame elements 20 and 22, or to the legs 14 and 16, or to all of these elements, forms, with the legs 14 and 16, rigid A frames at both sides of the chair to obtain a particularly strong construction resulting from the inherent characteristics of a triangular linkage. The
3,236,559 Patented Feb. 22, 1966 "ice seat 26 is confined between the inner faces of the side frames 11 and 12, as shown best in FIGURE 2, and thus the A frames formed by the legs 14 and 16, and the seat 26, will nest within one another to permit stacking of the chairs, as clearly shown in FIGURE 4.
In the illustrated construction, at the upper end 18 of each of the side frames 11 and 12 there is an upper element 28 which has its forward portions 30 connected to the side frames 11 and 12, and a mid portion 32 extending across the back of the chair. Thus, the forward portions 30 form arms for the chair and the mid portion 32 forms a part of the back of the chair. The arms need not be of one-piece construction with the back, however, and may be connected with a back panel of a captains chair, as previously explained and as shown in FIG- URE 6.
In the construction illustrated, the rest of the back is formed by a plurality of vertically-extending elements 36 which are separate from one another and which have their lower ends connected to the seat 26 and the upper ends connected to the mid portion 32 of the upper element 28. These connections at the upper and lower ends of the back elements 36 are rigid connections which brace the entire chair structure and which hold the elements 36 in fixed and preferably parallel relation to one another.
It is one feature of the invention that the forward portions or arms 30 are connected to the side frames 11 and 12 with the inside faces of the arms 30 in contact with the outside surfaces of the side frames 11 and 12. This spaces the arms 30 further apart than if they were located on top of the side frames and thus makes the chair more comfortable for an occupant without requiring that the entire chair be made wider. It also permits the arms to extend rearward to the back of the chair and to connect with the back. As shown in FIGS. 1 and 4, the A frames have upper surfaces at their vertices, and the forward ends of the arms have surfaces that are flush with the upper surfaces at said vertices of the A frames.
Although a more attractive appearance is obtained by having the arms 30 terminate at the side frames 11 and 12, these arms 30 can be made longer, if desired, so that they extend forward of the upper ends 18 of the side frames. The construction illustrated has the upper ends of the side frames located more than one-third of the distance from the back of the seat 26 to the front of the seat and thus termination of the arms 30 at the side frames 11 and 12 provides sufliciently long arms, especially in a chair which has a sloping back that locates the occupants shoulders more rearwardly than in a straight-back chair.
FIGURE 3 shows the transverse frame element 20 with a curved top surface that slopes downward to its lowest level at a mid region across the width of the chair. The rearward transverse frame element 22 is pre erably of similar construction. The seat 26 is made of a bottom layer of relatively thin plywood 42 which is curved to fit the transverse concave curvature of the frame elements 20 and 22. Metal strips 44 attached to the frame elements 20 and 22 and to the back elements 36 hold the frame elements 20 and 22 and the back panel elements 36 is a fixed position relative to each other. The strips 44 complete the side triangles, prior to the assembly of the seat.
On top of the plywood 42 there is an upholstered sea 46 secured to the plywood. In a transverse direction, the seat 46 has a concave curvature for greater comfort, and the upholstery is preferably built up somewhat at the front.
FIGURE 4 shows two chairs in stacked relation to one another. The lower chair is the chair illustrated in FIG- URES 1-3 and the upper chair is a like chair with corresponding parts indicated by the same reference characters but with a prime appended. It will be evident from FIG- URE 4 that the chairs are stacked by inserting the back legs 16 of the upper chair into the space within the arms 30 of the lower chair and into contact with the top surface of the corresponding legs of the lower chair. The arms 30 serve as abutments to prevent transverse displacement of the back legs 16 of the upper chair in the event of any shifting of the upper chair, and thus the chairs are held against distortion of the stack in a direction transverse of the chair while the nesting of the A frames holds the chairs against distortion of the stack in a fore-and-aft direction.
When chairs of the construction illustrated are stacked, the stack has a'slight forward slope, as illustrated by the lines 58 and 59. This slope permits the bottoms of the back legs 16 to pass the arm-back units of the chair frames.
Because of the extent of the upper element 28 beyond the rearward end of the seat 26, the elements 36 of the back can be provided with a rearward slope which permits nesting of the backs of the chairs, as clearly shown in FIGURE 4.
In order to prevent scratching of the legs where they contact with one another when stacked, the underside of each of the front legs is provided with a groove 52 into which a strip of pad-ding 54, preferably soft plastic, is inserted. I This padding 54 extends slightly beyond the surface of the back legs 16 and serves as a bumper to hold the hard surfaces of the legs out of contact with one another to prevent scratching. By having a high area 55 in the groove 52 at the location shown in FIG- URE 4, the padding 54 counteracts the taper of the legs and takes advantage'of it-to create the slight forward slope of the stack. Similar padding strips are secured in grooves in the under surfaces of the back legs 14, but without the high areas 55. The padding is preferably held in the grooves by adhesive'and'is of sufficient length to extend along those parts of the legs which contact with one another when the chairs are stacked.
FIGURE 6 shows a modified form of the invention in which the chair has a back panel 61 connected at its lower end with the frame assembly and with arms 63 at locations which may be substantially below the top of the panel 61. This captainschair has the arms 63 'secured to the back panel 61 but not of one-piece construction with the-back panel. Chairs of this kind can be made in different styles by using different panels (modern, early American, oriental,- etc.). The construction of this chair of FIGURE 6 is otherwise similar to that already described in connection with the other figures of the drawing.
The preferred embodiment of the invention has been illustrated and described, but changes and modifications can be made and some features may be used in different combinations without departing from the invention as described in the claims.
