, 19 Claims. (Cl. 297-232) I ABSTRACT OF THE DISCLOSURE There is disclosed a foldaway seating arrangement for use in co-operation with an auditorium railing and the like, said arrangement comprising a platform having foldable legs, said legs being exten'clable to position said platform adjacent a lower run of said railing in the operative position of said platform, seating means mountable on said platform, and rail engaging means secured to said platform for engaging an upper run of said railing to at least aid in suspending said platform from said upper railing run in a foldaway stored position of said platform and said seating means.

My present invention relates to foldaway seating platforms for use in auditoria, arenas and other places of large seated congregations, and more particularly to platform arrangements 'of the character described for use in cooperation with the steel or'other type of railing conventionally provided in such auditoria and the like to define the aisles and seating sections thereof.

conventionally it has been the practice in the operation of auditoria and the like, when unusually large crowds are anticipated, to provide large numbers of folding chairs to accommodate the overflow crowd. The folding chairs usually are placed in the aisles of the auditorium immediately behind the railing usually provided to delineate such aisles, particularly at the edges of balconies or other elevated seating section. Because the aisles usually are recessed considerably below the adjacent rows of permanent seats, temporary platforms are placed thereon, at convenient positions adjacent the railing so that the spectators in the temporary seating arrangements are seated at the proper elevation for'viewing the stage or the like over the heads of the audience in front of them and over the railing itself. I

The installation and subsequent removal of these temporary platforms with the required folding chairs thereon involves considerable time, labor and expense, in addition to the fact that the temporary platforms frequently become displaced from the railings by the press of the crowds passing through the aisles so as to distort the temporary seating arrangement and to block the remainder of the aisles. Moreover, the storaging of the temporary platforms, which are relatively large and bulky, together with the folding chairs used therewith requires considerable space and involves considerable expense not only in the provision of the storagefacilities but also in the time and labor involved in .transporting the platforms and folding chairs to and from the place or storage.

I have-solved these problems by providing novel forms of foldaway seating arrangements. In one form, the elevated platform for the folding chairs is provided with novel means both for temporary or permanently securing the platform as desired to the aforementioned railing during operation thereof to prevent displacement of the platform from the railing. When not in use my novel platform is provided with additional cooperating means for securing or suspending the unused platform against the railing for storage purposes in a position such that no appreciable obstruction is offered to the aisle adjacent the railing. In another arrangement of my invention the platform is provided with additional novel means for supporting the 3,394,963 Patented July 30, 1968 ice chairs when folded in the stored position of the platform, such that both the chairs and the platforms can be mounted in stored positions on those railing'sections at which the platforms are periodically used. The last-described arrangement of my invention wherein both the platform and the chairs are stored in situ likewise offers no appreciable obstruction to the adjacent aisles.

In still another arrangement of my invention foldable seat means are foldably or hingedly secured to each of the seating platforms, and the latter are pivotally or otherwise secured to the auditorium railing in such manner that both the platform and the folding seat means foldably secured thereto can be moved between their stored and operative positions with a minimum number of manipulations thereof, with the result that the time for setting-up and storing the last-mentioned foldaway seating arrangement is further reduced. The foldable seat means is provided either in the form of discrete folding chairs or of a continuous folding bench extending along the length of a given platform, with either the folding chair arrangement or the folding bench being hingedly or otherwise foldably secured to the platform. When not in use the platform with its folded seat means can be pivoted or otherwise moved to a suspended, storaging position on that section of auditorium railing at which the seating platform is used for temporary seating purposes.

In my first mentioned foldaway seating arrangement the necessary separate storage space is considerably reduced inasmuch as the bulkiest part of the seating arrangement, viz. the platforms, is stored at the location of their occasional use. In this case it is only necessary to convey the folding chairs to and from the storage facilities therefor. In the remaining arrangements of my novel seating platform both the platform and the chairs or bench used thereon are stored at the location of their use so that the aforementioned storage facilities are eliminated altogether and likewise the necessity of conveying folding chairs or the like to and from the locations of their use. In very large arenas or auditoria, such as are in use at the present-time, the savings resulting from decreased labor and the elimination of costly storage facilities for conventional temporary seating arrangements are very considerable.

During the foregoing discussion, various objects, features and advantages of the invention have been alluded to. These and other objects, features, and advantages of the invention, together with construction details thereof, will become apparent as the following description of certain presently preferred embodiments of the invention and certain presently preferred methods of practicing the same proceeds.

In the accompanying drawings I have shown certain presently preferred embodiments of the invention and have illustrated certain presently preferred methods of practicing the same in which:

FIGURE 1 is a partial isometric view of one form of a. temporary seating arrangement including a temporary seating platform provided for folding chairs or the like and arranged in accordance with my invention;

FIGURE 2 is an end elevational view of the seating arrangement shown in FIGURE 1;

FIGURE 3 is an end elevational view of the seating arrangement shown in FIGURES 1 and 2 but illustrated here in the foldaway or stored position of the platform;

FIGURE 4 is a partial isometric view of another form of foldaway seating arrangement in accordance with my invention and illustrating means for storing both the platform and the folding chairs used thereon at the Iocation of their use;

FIGURE 5 is an end elevational view of the seating arrangement shown in FIGURE 4;

FIGURE 6 is a partial isometric view of still another form of my foldaway seating arrangement showing interconnected foldaway platform and seating means in their operative position;

FIGURE 7 is an end elevational view of the seating arrangement of FIGURE 6;

FIGURE 8 is a partial isometric view showing the seating arrangement of FIGURES 6 and 7 in its foldaway position; and,

FIGURE 9 is an end elevational view of the seating arrangement as shown in FIGURE 8.

Referring now more particularly to FIGURES 1 to 3 of the drawings, the exemplary form of novel, foldaway seating arrangement 10 shown therein is arranged for use in cooperation with railing 12 usually provided in arenas, auditoria and the like as mentioned previously. The railing 12, therefore, usually includes a number of standards or supports 14 and horizontal runs 16. Usually the standards and runs 14, 16 are fabricated from steel pipe and suitable fittings (not shown) provided for example to connect sections of the pipe. However, railings of other construction are obviously contemplated.

The seating arrangement 10 proper includes a platform or table 18 having

foldable legs

20 and 22 adjacent the front and rear edges thereof respectively. The legs, 20, 22 in this example are provided with conventional hardware indicated generally by reference character 24 of a collapsible nature. In this arrangement it is contemplated that a number of the tables 18 be provided and distributed along the length or lengths of the railing 12 as required for the anticipated excess crowds. For convenience in handling, each of the tables 18 is provided in such length to accommodate in the order of about six folding chairs 26. It is to be understood, however, that the number of chairs 26 supported on a given table 18 can be varied as desired, along with the length of the table. Desirably the chairs 26 are positioned along the length of the table or platform 18 and prevented from displacement across the top surface 28 thereof by means of an apertured strip 30 secured to the top 28 of the table and extending in this example along the rear lateral edge portion of the table 18. The strip 30 is provided with a number of apertures 32 which are spaced to receive in this example the lower end portions 34 of the rear chair legs 36. Desirably the apertures 32 extend entirely through the safety strip 30 so as not to cause the chair 36 to be tilted forward.

Railing engaging means including a number of 2-positioned brackets 38 are secured at spaced intervals along the front edge portion of the table 18 as better shown in FIGURE 1. In this example, three such brackets are so utilized, although the number obviously can be varied, depending on the application of the invention. Each of the brackets 38 includes an angular or bracket section 40, whereby the brackets 38 are secured to the table 18, and a first arcuate section 42 for complementary engagement over the adjacent top surface of the lower run 16A of the railing 12. It is contemplated of course that a shape other than that shown can be imparted to the brackets section 42 depending upon the given cross sectional configuration of the railing run 16A. The brackets 38 as thus far described thus prevent the table 18 from being displaced rearwardly of the railing 12 and from consequently blocking the remainder of aisle 44. It is also contemplated that sufficient structural stength can be imparted to the brackets 38 or that additional numbers thereof can be provided as desired to support entirely the front portion of the table 18, in which case the front legs 20 thereof can be eliminated, where permitted by applicable codes.

As better shown in FIGURE 3 of the drawings the 2- positioned bracket 38 has an additional function. When the sitting arrangement 10 is not in use, the table 18 is stored at the location of its use by securing the table 18 to the railing 12. In the latter arrangement of the invention the bracket 38 is provided with an additional arcuate section 46 adjacent the outer end portion thereof so that the table 18 with its

legs

20, 22 now in their folded positions,

can be suspended from the uppermost run 16B of the railing 12. It will be seen in the arrangement shown that the table 18 can be thus stored on the railing 12 on either the front or rear side thereof. In any event the table 18 when in its stored position as shown in FIGURE 3 offers little or no obstruction to the adjacent aisle 44. With this arrangement only the folding chairs 26 have to be conveyed from and to additional storage facilities therefor. The bulkier platforms such as the platform 18, however, can be secured along the length of the railings such as the railing 12 at the respective locations of their subsequent use.

To prevent inadvertent removal of one or more of the tables 18 additional, cooperating railing engaging means including brackets 48 can be secured along the rear edge portion of the table 18 is accordance with another feature of the invention. The brackets 48 are of single position construction and include base section 50 for securance desirably to the underside of the table 18 and an arcuate section 52 adjacent the outer or free end of the brackets 48. The

brackets

38 and 48 desirably are fabricated from a resilient structural material such as hot rolled steel so that, when the brackets 38 are initially engaged over the top run 16B of the railing 12, the cooperating brackets 48 can be snapped under the adjacent surfaces of the lowermost run 16A. This produces a snapped-in clamping action to secure or suspend the table 18 in its stored position against the railing 12. The

arcuate sections

46 and 52 of the

brackets

38 and 48 respec tively can be varied to suit the configurations of railing runs 16A, 16B as described previously in connection with arcuate sections 46 of the brackets 38.

In the event that the

brackets

38, 48 are not suflicient- 1y resilient or that the cross sectional configuration of railing runs 16A, 16B do not lend themselves to the aforedescribed, co-operative snap action of the brackets, at least the lower brackets (as viewed in FIGURE 3) are secured to the table 18 with wing nuts or thumb screws 54 to permit loosening of the brackets 48 and fitting around the railing runs, such as runs 16A, 16B followed by tightening the thumb screws 54 to clamp the table against the adjacent portion of the railing 12.

With reference now to FIGURES 4 and 5 of the drawings a modified form 10' of my seating arrangement is illustrated wherein similar reference characters with primed accents refer to similar components of FIGURES 1 to 3. In the open or operative position (not shown) of the seating arrangement 10' the disposition of the various components is substantially as shown in FIGURES 1 and 2 of the drawings. Thus, the table 18' in its unfolded or operative position is stabilized or supported as desired at the lowermost railing run 16A by railing engaging means including arcuate section 42' of each 2-position bracket 56. In the stored position of the table 18' the brackets 56 cooperate with additional railing engaging means including brackets 58 to spacedly secure the table 18 to railing runs 16A and 16B. In furtherance of this purpose the

brackets

56, 58 are provided with intermediate elongated sections 60 and 62 respectively to space their rail engaging sections 46 and 52' farther outwardly from the table 18 in comparison with the

brackets

38, 48 of the table 18 in FIGURES 1 to 3. The

brackets

56, 58 otherwise function in much the same manner as the

brackets

38, 48 described above with reference to FIG- URES l to 3.

This outward spacing of the table 18' from the railing 12' affords a storage space 64 into which those chairs 26 which are utilized with a given one of the tables 18 are inserted in their folded positions as illustrated. The chairs 26' when thus stored are supported and thus prevented from sliding downwardly from between the railing 12' and the juxtaposed table 18' by means of an elongated supporting strip 66 secured by suitable means along the lower lateral edge 68 of the table 18', as viewed in FIGURES 4 and 5.

The form of my seating arrangement of FIGURES 4 and 5 presents the added advantage of providing storage for both the platforms 18' and the folding chairs 26 used thereon at each location of their use. In the foldaway position of the platform 18' and chairs 26 a very compact arrangement is obtained which does not introduce any substantial obstruction into the adjacent aisle.

In FIGURES 6 to 9 of the drawings still another form 110 of my novel seating arrangement is disclosed, which is compact and still more easily manipulated between the operative and foldaway positions thereof. The seating arrangement 110 includes a platform 118 arranged to cooperate with a permanently installed railing 12' described before. The table or platform 118 is likewise provided with

folding legs

120, and 122, which are similarly braced by collapsible brackets 124. Foldable seating means 125 are hingedly or foldably joined to the platform 118.

One form of such foldable seating means includes a foldable bench 126 hingedly secured at 127 to an up right strip 128 secured along the upper rear edge portion of the table 118. The foldable bench 126 further includes a seat portion 129 hinged to its back panel .130 at 131 and a leg portion 132 hinged to the seat portion 129 at 133. The hinges 127,131, and 133 are sufficiently strong to support the anticipated weight and thus the hinges, particularly hinges 127 and 131, can be furnished in the form of conventional piano type hinges.

To stabilize the foldable bench 126 in its upright position as shown in FIGURES 6 and 7 a stabilizing strip 134 is mounted on the table 118 and is provided with a groove 135 into which the lower end portion of the leg panel 132 is inserted. Desirably the foldable seating means

panels

129, 130, 132 andthe stabilizing strip 134 extend along the entire length of the platform 118. Although the seating means 125 has been illustrated as a continuous bench 126 coextensive with the platform 118, it is also contemplated that the seating means 125 can take the form of discrete folding chairs of similar construction by interrupting the panels 129, .130, 132 thereof as denoted by chain lines 136 to provide individual chairs 137, as better shown in FIGURES 6 and 8. It is also contemplated that conventional folding chairs, .such as either of the types shown in FIGURES 4 and 5 can be hingedly or foldably jointed to the platform 118.

Along the front edge portion of the platform 118 railing engaging means including a number of pivot brackets 138 are secured. In this example each of the brackets 138 includes an O-clamp section 140 which is relatively closely fitted around the adjacent portion of the lowermost railing run 16'A. The brackets 138 thus stabilize the platform 118 to prevent displacement from the railing 12. If desired the front legs 120 can be removed as discussed in connection with the legs of FIGURES 1 to 3 of the drawings. In the present arrangement the brackets 138 are permanently and pivotally joined to the railing run 16'A so that the platform 118 can be pivoted from its operative horizontal position as shown in FIGURES 6 and 7 to its vertical or storage position as shown in FIGURES 8 and 9.

Before thus folding away the platform 118, however, the seat means 125 which are hingedly and permanently joined to the platform 118 in this example, are folded downwardly against the upper surface'of the platform 118. This is accomplished by raising the leg panel 132 and seat panel 129 upwardly along the paths denoted by arrows 142 and 144 respectively, which first displaces the lower end ofthe' leg panel 132-from the stabilizing strip 134 and then finally folds the

panels

129, 132 against the upper front portion of the back panel 130. The seat means 125 with the

panels

129, 132 thus folded, are then folded downwardly along the path denoted by arrow 145 such that the seating means 125 assumes a foldedposition against the supporting platform surface 119 substantially as shown in FIGURES 8 and 9 of the drawings. Following this operation the platform 118 is pivoted about 6 clamp sections 140 to the foldaway position of the seating arrangement as shown in FIGURES 8 and 9 of the drawings.

To retain the foldaway seating arrangement 110 in its storage position (8 and 9) additional railing engaging means including cooperating brackets 148 are secured adjacent the rear of the platform 118 to lateral platform extension 149 by means of their base sections 150. The brackets 148 are further provided with complementary rail-engaging sections 152 which, owing to the resiliency of the brackets 148 and base 138, can be snapped over the adjacent upper surfaces of the uppermost railing run 16'B. However, to prevent inadvertent rem-oval of the seating arrangement 110, when in its foldaway position, complementary clamp sections 154 can be bolted or otherwise secured to the snap over sections 152 to complete an O-clamp section thereat. It is also contemplated that all of the

clamp sections

140 and 154 can be omitted and that the platform 118, when not in use, can be merely suspended from the top railing run 166 by reversing the railing engaging means 148 to the position of the railing engaging means as shown in FIGURES 3-5. The platform legs and 124 are subsequently folded as better shown in FIGURE 9 of the drawings.

When the seating means are provided in the form of individual folding chairs 137, the cooperating railing engaging means brackets 148 can be secured inwardly of the chair supporting strip 128 and between adjacent chairs, as denoted by chain-outlines 156 thereof in FIG- URES 6-8. In this alternative the platform extension 149 can be omitted.

The height of the chair means supporting strip 128 above the surface of the platform 118 desirably is sufficient to permit folding of the seating means 125 to a substantially parallel array of its

panels

129, 130, 132. In addition the

brackets

138 and 148 desirably are provided with intermediate section-s 160 and 162 (FIGURE 9) respectively to provide sufiicient space 164 between the railing 12 and the platform 118 to accommodate the folded seating means 125.

- The last-described form of my foldaway seating means 110, in addition to storaging a large number of such seating arrangements such as the platform 118 and the associated seating means 125 at their respective locations of intended use, considerably reduces the time and labor required in setting up and folding away the seating arrangement 110. In a relatively large arena or auditorium the total savings in such time and labor are enormous, not to mention the savings involved in eliminating separate storaging or warehousing of conventional temporary seating arrangements.

It is to be understood, of course, that certain features of my invention can be interchanged or transposed among the various forms of my foldaway seating arrangements. For example, the railing engaging means of FIGURES 6-9 can be employed in the seating arrangements of FIG- URES l-3 or FIGUR'ES 4-5, and conversely, the railing engaging means of FIGURES 4-5 can be used in the organization of FIGURES 6-9, as desired in a particular application of the invention.

From the foregoing it will be apparent that novel and efficient forms of foldable seating arrangements have been disclosed herein, part or all of which are storagea'ble on location.
