Nash, Ferguson, Mo., assignor to Chromcraft Corporation, St. Louis, Mo, a corporation of Missouri Filed Apr. 22, 1960, Ser. No. 24,151 7 Claims. (Cl. 297-239) This invention relates to new and useful improvements in chairs.

At the present time, hotels, churches and similar user of chairs are presented with a serious storage problem. When auditoriums are used to seat people, it must be filled with chairs, but when used for dances or similar social functions, the floor must be cleared and the chairs stored elsewhere. For years folding chairs have been used to meet this need but such chairs are not overly comfortable and, moreover, require an appreciable amount of time and effort to set up or take down. A similar problem confronts the manufacturer and reseller in shipping and warehousing such chairs. In order to economize on shipping costs, it is desirable to package and ship chairs, which have been completely assembled at the manufacturers plant, in a stacked condition whereby a substantial amount of shipping space is saved.

For these various reasons, the chairs should be so designed and constructed that they may be telescopically nested one on the other, such that a stack of chairs will nest snugly and compactly upon each other and will not be likely to become damaged when so nested.

When such chairs are used in large auditoriums, exhibition rooms, and the like, it is also desirable to provide means for retaining the chairs in interlocked horizontally aligned relationship with respect to each other, whereby a row of relatively fixed seats in the auditorium, or the like, may be readily formed.

it is, therefore, one of the objects of the present invention to provide a chair which is adaptable for shipping and storage in telescopically stacked relation with other similar chairs and which is provided with interlocking means for aligning a plurality of said chairs in horizontal registration in an auditorium, exhibition room, or the like.

it is also an object of the present invention to provide a chair having a frame so constructed that a plurality of completely assembled chairs may be telescopically nested one upon the other for purposes of shipment without becoming interlocked with or damaging the chair either above or below it.

It is a further object of the present invention to provide a chair of the type stated in which the chair may be telescopically stacked with other chairs of the same type in such manner that the seat is held in slightly spaced relation from the immediately adjacent chairs.

It is an additional object of the present invention to provide a chair of the type stated in which the means for holding the chair in telescopically stacked relation also functions as a means for interlocking with an adjacent chair of the same type to provide-an aligned horizontal row.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

Referring now in more detail and by reference characters to the drawings, which illustrate practical embodiments of the present invention, A designates a chair integrally comprising a frame member 1 formed of hollow metallic tubing and a seat portion 2, the seat portion 2 being preferably, though not necessarily, a single piece of molded plastic which is secured to the frame member 1 to form an integral structure therewith. The frame member 1 comprises a forward tubular member 3 and a rear tubular member 4. The forward tubular member 3 is substantially U-shaped and includes a pair of parallel legs 5, 6, which are integrally joined by a bight 7, the bight 7 having a centrally located horizontal portion 8 which is connected to the legs 5, 6, respectively, by downwardly angled portions 9, it), in such manner that the horizontal portion 8 is displaced above the bends i1, 12, which join the legs 5, 6, to the portions 9, 1d. The rear tubular member 4 is also substantially U-shaped and includes a pair of parallel legs 13, 14, which are integrally joined by a bight 15 having a centrally located horizontal portion 1-5 which is connected to the legs 13, M, by a pair of opposing upwardly extending portions 17, 18, in such manner that the bends 19, 20, of the rear tubular member 4- are spaced above the horizontal portion 16, as shown in FIG. 2. It should be noted that the legs 5, 6, and 13, 14, are respectively coplanar and that the complementary legs 5, 13, and 6, 14, of the forward and rear tubular members 3, 4,. are likewise coplanar with respect to each other.

Welded to, and extending between, the horizontal portions 8, 16, in spaced relation is a pair of diverging fiat bars 21, 22, which are respectively provided with spaced apertures 23, 24, and 25, 26, for purposes presently more fully appearing. Welded to, and extending between, the complementary legs 5, 13, and 6, 14, are brackets 27, 23, comprising rung-forming horizontal bights 29, 30, a pair of outer downwardly projecting elements 31, 32, 33, 34-, lower horizontal elements 35, 36, 37, 38, and up- Wardly extending elements 39, 40, 41, 42. It should be noted that the elements 29, 31, 35, 39, and 29, 32, 36, 40, in combination, define a pair of quadrilateral rein- 3 forcing frames 43, 44, on the bracket 27, and in like manner, the elements 34 33, 37, 41, and 3t}, 34, 38, 42, also define a pair of spaced quadrilateral reinforcing frames 45, 46, on the bracket 28.

Inserted in the lower extremities of the legs 5, 6, 13, 14, are glides 47 each comprising a tubular shell 48 having an integrally formed concave dome 49 at one end thereof, the concave dome 49 being provided with a centrally located aperture 5%. The glide 47 includes a spring-like element 51 and a sliding element 52 which is preferably, though not necessarily, composed of a material having a low coefiicient of friction, such as Teflon, polyethylene, or the like, for slidable movement over a floor 1 without causing unsightly scratching or marring. The slide 52 includes an upwardly projecting convex dome 53 which is complementary in size to the concave dome 49 and which is in abutment therewith. Preferably, though not necessarily, the slide 52 has a metallic cover 54 of the same material as the tubular members 3, 4, to preserve the attractive metallic appearance of the chair. The spring 51 and the slide 52 are also provided with centrally located apertures 55, '56, the aperture 56 and the slide 52 being somewhat enlarged, and the spring 51 and the slide 52 are riveted to the shell 48 by means of a rivet 57 which extends through the aligned apertures 50, '55, 56, as shown in FIG. 9. The enlarged aperture 56 and the slide 52 permits pivotal movement of the slide 52 with respect to the shell 48, whereby the same glide 47 may be used in each of the legs 5, 6, 1 3, 14, and support the chair A securely on the floor f.

The seat portion 2 is preferably, though not necessarily, fabricated from a single piece of fibrous reinforced synthetic resin, such as fiber-glass, and includes a seat 58 and a back Sit, which are contoured to conform to the human body in the seated position. The seat 58 and the back 59 are provided with a continuous encircling rim 6G for structural support. Bonded to the underside of the seat 58 in spaced relation are rubber disks 61, 62, 63, 64, each of which is of limited resiliency and includes a conventional nut 11 rigidly embedded therein. The rubber disks 61, 62, 63, 64, are located on the seat 58 in such manner that the threaded portions of the nuts 11 will be in substantial alignment with the apertures 23, 24, 25, 26, in the fiat bars 21, 22, whereby, when bolts b, having lock-washers l, are passed through the apertures in the fiat bars 21, 22, and secured to the nuts 11, the seat portion 2 and the frame member 1 will be firmly secured one to the other. It should be noted that the seat 58 is slightly narrower in transverse dimension than the overall distance between the leg members 5, 6, and 13, 14, as shown in FIG. 2. It should also be noted that the horizontal bights 29, 30, of the brackets 27, 28, are horizontally coplanar.

When a plurality of chairs A are to be shipped or stored, the chairs A are stacked in vertically nested relationship in the manner shown in FIG. 6, one chair A being placed directly on top of a second chair A in such manner that the horizontal bights 29, 30, respectively rest on the bends 11, 19, and 12, 20, of the tubular members 3, 4, whereby the seat portion 2 of the upper chair A is held in spaced relation from the seat portion 2 of the lower chair A, as shown in FIG. 6. The reinforcing frames 43, 44, 45, 46, defined by the elements of the brackets 27, 23, coact with the bends 11, 12, 19, 28, to retain the various chairs in the vertically stacked position, the elements 35, 36, coacting with the legs 5, 13, to prevent the chairs A from moving from left to right, and the elements 37, 38, coacting with the legs 6, 14, to prevent the chairs A from moving right to left with respect to each other, as shown by FIGS. 7 and 8. In addition, it can be readily seen that, when the chairs A are vertically stacked, the chairs are prevented from moving forwardly and rearwardly by the coaction between the elements 31, 32, 33, 34, and the legs '5, 13, 6, 14, respectively. Thus, it can be seen that, when the chair is desired to be placed into a shipping condition, a substantial plurality of chairs may be stacked one upon the other, resulting in a reasonably rigid structure which is suitable for safe, harmless shipping.

With particular reference to FIGS. 10 to 15, inclusive, A designates a modified form of chair, which is substantially similar to the chair A except that it is provided with brackets 27, 28, which respectively include horizontal nights 29', 3%, pairs of downwardly projecting elements 31'32 33-34', pairs of lower horizontal elements 3536, 37-38, and upwardly extending returns 3--4t-, 41-42. The returns 3'4ti and d1'42 are located in position to rest upon the bends 11, 19, and 12, 20, respectively, when the chairs A are stacked in very much the same manner as the previously described elements 35, 36, 37, 38, of the chair A shown in FIG. 6. However, the bracket 28 diifers from the bracket 2%" in that the elements 35, 36, are longer than the elements 37, 3%, as can be seen by comparison of FTGS. ll and 12. Moreover, these elements 35, 36, 37', 3 3, are located outwardly with respect to the legs 5, 6, so that when two chairs A are placed in side-by-side relation these elements can be interengaged or hooked into one another, so to speak, as shown in FIGS. 13, 14, and 15. The chairs A can, therefore, be stacked or ganged as the user wishes.

It is also possible to provide a further modified form of chair B as shown in FIGS. 16 to 2l, inclusive, which is substantially similar in construction with the previously described chairs A and A, insofar as the stacking feature is concerned. However, the chair B is provided with brackets 65, 66, which integrally include horizontal rungforming bights 67, 68, downwardly extending pairs of elements 69-70, 71-72, and inwardly turned horizontal elements 73-7 i, 7576, respectively. The elements 7374 of the bracket 65 are integrally joined at their inner ends to upwardly extending vertical legs 77, 78, respectively, which are, in turn, bent outwardly adjacent their upper ends in the provision of U-shaped retention hooks 79, 853'. At their uppermost ends the legs 77, '78, are integrally joined to outwardly extending horizontal elements 81, 82, which are displaced inwardly and upwardly in relation to the elements 73, 74, respectively. These elements 81, 32, engage the bends 11, 19, of the leg 5 for stacking purposes in the manner heretofore described.

Similarly, the elements 75, 76, of the bracket 66 are integrally joined at their inner ends with upwardly extending somewhat vertical legs 83, 34, which are bent laterally toward the chair B in the formation of offset elements 85, 86, and these are, in turn, bent outwardly in the provision of horizontal elements 87, 38, which are displaced inwardly and upwardly in relation to the elements 75, 76. These elements 87, 88, engage the bends 19, 2%, of the leg 6 for stacking purposes in the manner heretofore described.

As may be seen by reference to FIGS. 19, 20, and 21, two of the chairs B may be engaged in side-by-side relation, or ganged so to speak, by lifting one of them several inches upwardly until its bracket 66 is well above the bracket 65 of the adjacent chair B. In this relative position the legs 83, 84, are vertically over the retention books 79, 8%, and when the lifted chair B is moved straight down again so as to rest upon the floor, these legs 83, 84, will drop into engagement behind the hooks 79, 80, and the two chairs B will thereby be held in ganged position. This arrangement forms a very positive lock between the two chairs B but is, nevertheless, easy to engage or disengage as may be desired. Moreover, for greatest universality in use, it is often desirable to set a number of chairs B beside each other, as for instance around banquet tables, and under such circumstances the chairs are not ganged. When so used, the ganging arrangement of the present invention will not become unauthorizedly or accidentally interlocked.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the chairs may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what 1 claim and desire to secure by Letters Patent is:
