United States Patent 3,262,733 TABLE AND SUSPENDED CHAIR UNIT Herman Wendell Black and Kae Derham Black, both of Blackfoot, Idaho, assignors of thirty-five percent to Richard R. Wright, Idaho Falls, Idaho Filed July 6, 1965, Ser. No. 469,425 9 Claims. (Cl. 297-142) This is a continuation-in-part of application Serial No. 348,043, filed February 28, 1964, now abandoned.
The present invention relates to combined table and seat units and is especially concerned with a unit of the type wherein one or more chairs are suspended from a table structure.
Conventional arrangements, including a table and separate chairs, involve a number of legs on the table and additional legs on each chair. The numerous legs make it very difiicult to clean floor areas beneath the table and chairs, especially without marring the legs. Furthermore, it is frequently impossible to store the chairs beneath the table and it is necessary to move the chairs to and from the table each time they are used.
In the past there have been combined table and seat units proposed, and these have overcome some of the problems inherent in separate table and chair arrangements. However, the combined table and seat units with which we are familiar are not entirely satisfactory from one or more standpoints. Thus, the tables may include corner legs that obstruct cleaning operations and/or the table may not be adapted to be securely mounted such that it will be stable even if the seats are loaded unevenly. In addition, the structure used to support the seats often obstructs a user moving on or oflf the seat and makes it difiicult for him to properly position and maintain himself with respect to the table.
Objects of the present invention are to provide a combined table and seat unit wherein the seats are conveniently positioned beneath the table when they are not in use and wherein a maximum clear area is provided therebeneath so that cleaning operations are not obstructed. Further objects are to provide a unit wherein the seats are suspended from the table in such a manner that they tend to pivot to the storage position beneath the table when they are unoccupied, but tend to maintain a set position when they are occupied.
Outstanding features of the present invention include a central post support for both a table top and seats associated with the table top. The seats are carried by an arm journaled for rotation with respect to a downwardly extending, outwardly inclined, seat support bracket that includes a friction braking assembly. With this arrangement the seats tend to swing under the table top when they are unoccupied but the braking force opposes swinging when the seats are occupied.
There are shown in the accompanying drawings specific embodiments of the invention representing what are presently regarded as the best modes of carrying out the generic concepts in actual practice. From the detailed description of these presently preferred forms of the invention, other more specific objects and features will become apparent.

FIG. 6, a view like FIG. 4, but showing another embodiment of the friction brake.
Referring now to the drawings:
In the embodiment illustrated in FIGS. 14, the table and seat unit of the invention is shown generally at 10 and includes a table top 11, and a plurality of suspended seats 12, all indirectly supported by a central upright post 13. Post 13 is threaded into a coupling 14 of a subfioor mounting assembly shown generally at 15.
The sub-floor mounting assembly comprises an H frame anchor member having a pair of angle irons 16 and 17 drilled with holes so that screws 18 can be passed through and screwed into the floor joists of the building in which the unit is to be mounted. A cross tube 19 is fixed to each of the angle irons, as by welding, and coupling 14 is rigidly fixed thereto. It should be obvious that for other types of sub-floor constructions, other types of anchor members can be used. In all cases, however, the coupling 14 must be positioned to hold central post 13 in a vertical position.
A pipe ring 20 surrounds central post 13 and rests on the building floor 21 to provide an attractive cover for the opening made through the floor to accommodate post 13.
A horizontally extending arm 22 is fixed to upright post 13 at its upper end to directly support table top 11 and one or more of the suspended seats. Horizontally extending braces 24 are fixed to arm 22 and are screw connected to the inner faces of side aprons 25 of the table top.
The seats 12 are each suspended through a seat support bracket 26 connected to one of the arms 22 beneath the edge of the table, and by a seat supporting arm 27 that has one end 27a journaled for rotation in a seat support bracket and the other end 27b journalling a post 28, FIG. 5, that is fixed to and depends from the bottom of a seat.
Seat support brackets 26 each include a channel member 29 that is welded to arm 22 and that extends downwardly and slightly outwardly with respect to table top 11. A bearing plate 30 extends across the channel member 29, between the flanges 29a, to provide a bearing surface for a pair of the seat supporting arms 27.
Each arm 27 has a nut 31 welded to its end 27a so that a bolt 32, passing downwardly through holes 33 in bearing plate 30, can be screwed into the nut. A lock nut 34 on the bolt is turned down tight against nut 31, and the bolt will then rotate with the arm 27. A replaceable bearing washer 35 is positioned between the head 32a of bolt 32 and bearing plate 30 to take the wear resulting from horizontal swinging of arm 27.
In the embodiment illustrated in FIGS. 14 the upwardly extending end 27a of arm 27 is normally held in position adjacent the web 29b and one flange 29a of channel member 29 by a block 36 that slides on bolts 37. Bolts 37 are threaded into nuts 38 fixed to the web 29b of channel member 29, and a spring 38, FIG. 4, is positioned between the block and the head of each bolt to normally bias the block against the end 27a of arm 27 and the arm against the channel member 29.
The frictional engagement between the block, the arm, and the channel member provides a resistance force to horizontal rotation 'of the arm 27, but when the seat at the opposite end 27b of arm 27 is unoccupied this resistance force is not great enough to overcome the natural tendency of the arm to swing the seat under the table, resulting from the slight outward sloping of the seat support bracket with respect to the table. Post 28, depending from the seat into end 27b of arm 27, is angled such that the seating portion of the seat will be maintained in a substantially horizontal position.
When the seat is occupied, the lower portion of the upwardly extending end 27a of arm 27b is forced tightly against block 36, which is then forced tightly against the head of bolt 27, with the resulting frictional force acting as a brake that opposes undesired swinging of the arm. Of course, the frictional force is not sufiicient to prevent a user forceably pivoting the arm to a desired position. Block 36 is preferably made of hardwood, but it should be apparent that other materials having the desired wear and frictional properties can be used.
In FIG. 6, there is illustrated another friction brake assembly that has been found very satisfactory. As in the previously disclosed embodiment, this assembly includes a channel member 40 against which the seat supporting arm 27 is lightly biased. A post 41 is Welded to channel member 40, and a V-shaped friction block 43 slides on post 41 so that each "of its legs rests against one of the ends 27a of an arm 27. A spring 44, positioned between a nut 45 threaded on the end of post 41 and a flat washer 46 that engages the block provides the normal biasing force for holding the wedge against the arms 27 and the arms against the channel member. The tension can be varied as desired merely by turning nut 45 and changing the compression of spring 44. When a seat is occupied the end 27a of its arm 27 is forced tightly against the friction block, which is then forced tightly against the nut 45 (with Washer 46 and spring 44 therebetween) to apply a braking force opposing horizontal swinging of the seat supporting arm.
Extender members 47, FIG. 5, are provided as a very inexpensive and effective way of changing the elevation of the seats. Each extender member includes upper and lower cylindrical sections 48 and 49, respectively, with the lower section having an outside diameter small enough to easily fit into the tubular bore of end 27!) of seat supporting arm 27 and the upper section having an inside diameter large enough to easily receive the depending post 28 of a seat.
As has been noted, two seats are easily suspended from a single seat-support bracket and the same brake mechanism will act to prevent undesired horizontal swinging of arms carrying such seats.
With the seat suspension and braking arrangement of the invention, the support structure for the seat is well out of the way of a user as he swings toward and away from the table top, and the seat will be maintained in any set position, without a tendency to float the user away from the table. Also, with this arrangement, there is only a central support post for the table top and seats that must be avoided during cleaning of the floor beneath them, and the seats are positioned beneath the table top where they are easily accessible when they are not being used.
Whereas there are here illustrated and specifically described a certain preferred construction of apparatus which is presently regarded as the best mode of carrying out the invention, it should be understood that various changes may be made and other constructions adopted without departing from the inventive subject matter particularly pointed out and claimed herebelow.
