This invention relates to seat constructions,

and has for an object the provision of a novel design of seat, which, while bemg capable of substantially universal application, af-

fords. particular convenience for use in restaurants, ice-cream parlors, andthe like.

A more detailed object is the provision of a seat construction wherein the seat may be pulled forward when occupied, but wh ch may be pushed back into retracted position to afford greater convenience to the person getting into or out of the seat.

Another object is to provide an adjustable seat as described, in which the back also is adjustable, and is connected to the seat itself, so that the back is moved simultaneously with movement of the seat.

A further object is to provide an adjustable seat construction as described, whichisof the 1 knockdown" type, permitting shipping and /orv storage of the entire seat construction within a relatively small space, and also permitting facile assembly, thereof when desired.

construction having the above described characteristics, which is of unusually simple and rugged design, and which may be produced at relatively low cost. I V

The invention possesses other objects and advantageous features, some of which, with those enumerated, will be set forth in the following description of the inventions particular embodiment which is illustrated in 1 the drawing accompanying and forming a part of the specification.

Referring to the drawing: Fig. 1 is a perspective View of an assembled seat construction having the principles of 401' the present invention incorporated therewith. Fig. 2 is a vertical transverse sectional view. I i

Fig. 3 is a perspective view of the frame which forms a portion of the seat construction of the present invention, and the associated portions of the end walls showing the cleats thereon, whereby the frame is'mounted in operativenposition. Portions ofthe end walls are broken away to reduce the size of BD-the figure. Y

A still further object is to provide aseat My improved seat construction comprises a pair of spaced

end walls

6 and 7, each of which comprises an enlarged base portion 8 and a back supporting ortion 10. Whereas it is entirely within t 1e scope of the present invention to arrange my improved seat 1 construction as a single seat, Fig. 1 illustrates the invention as being incorporated in a structure providing seats for four persons, A there being two seats upon each side of the device. Accordingly, the enlarged'base portion 8 of each

end wall

6, 7 projects beyond both edges of the back supporting portion 10, as clearly illustrated upon Figs. 1 and 2.

Each of the

end walls

6, 7 has a cleat 9 rigidly, and preferably permanently, secured to the inner face thereof. These cleats 9 are at the same elevation above the lower edges 11 of their

respective endwalls

6, 7. Preferably, each end of each cleat 9 is provided with a tenon 12, whereby a frame, which is indicated in its entirety at 13, may easily be mounted thereupon. This frame com rises

bars

14 and 15 retained in spaced para lel relationship by atransversely extending bar 16 and a transversely extending board or seat guide member 17 upon each side of the bar 16 and parallel thereto. Each end of each of the

bars

14 and 15 is provided with a mortise 18 adapted to receive one of the tenons 12, whereby the frame 13 may substantially instantaneously be mounted upon both cleats 9, as will readily be understood.

Thetwo

end walls

6 and 7 are rigidly, but demountably joined by a bar 21 which is secured thereto by any suitable releasable fastening means, such as conventional wood screws 22. I preferably employ a second bar 23 extending between the two

end walls

6 and 7 adjacent theirlower edges and similarly secured thereto. The parts are so proportioned and arranged that when the

end walls

6 and 7 are fastened to the horizontal bars 21'and 23, they will be so spaced that the

bars

14 and 15 are rigidly clamped be- I tween the

end walls

6 and 7 and engaged by the tenons 12 of the cleats 9,.so as to impart rigidity to the frame 18, which is thus supported horizontally between the two

end walls

6 and 7. If desired, conventional corner plates 24 may then be mounted in such a manner as to impart rigidity to each intersection of the

bars

14 and 15 with the cleats 9.

A rod 26 is rigidly secured to, and extends between the two

end walls

6 and 7, this rod extending horizontally and closely below the upper horizontal bar 21. A plurality of seat backs 27 are suspended by being pivotally mounted adjacent their upper edges upon the rod 26. For this purpose each of the backs 27 is provided with preferably a pair of hook shaped strips 28 which engage the rod 26.

A seat 29 is associated with each of the backs 27, the after edge of the seat being pivoted adjacent the lower edge of the back 27 by means of any suitable hinge construction 31. However, instead of supporting the weight of the seat 29 and that of a person seated thereupon by means of the back 27, this weight is supported by the horizontal frame 13, inasmuch as all the seats 29 are supported thereupon, the association between the seats 29 and the frame 13, however, being such that each seatmay be adjusted substantially in a hori zontal plane, so as to vary the distance that the seat extends beyond the forward or outer edge of the frame 13. In Fig. 2 the seat illustrated at the left hand side of the figure is shown as being fully retracted, whereas the seat illustrated on the right hand side of the figure is shown in extended position.

To facilitate this adjustment of the seat, each seat is supported upon the frame 13 through the expedient of rollers 32, preferably four rollers being provided for each of the seats,two adjacent each of the lateral edges thereof. The rollers 32 adjacent one of the lateral edges of each seat 29 rest upon one of the'cleats 9, whereas the other rollers of that seat rest upon the central bar 16 of the frame 13.

When the seats are in retracted position, the rollers 32 thereof which are adjacent their after edges engage within depressed portions '33 which are provided in the central bar 16 and in the cleats 9. Each of these portions 33 provides inclined faces sloping upwards and toward the outer edges of the frame 13, i. e., they slope upwards and from the central portion thereof, the purpose of this arrangement being to cause the after edge of each seat 29 to be raised slightly as the seat is pulled forward, thus compensating for the slight amount of upward motion of the seat back 27, which is caused by the arcuate motion of the back when pulled forward. That portion of the associated cleat 9 and the central bar 16 which the forward rollers 32 engage, is preferably perfectly horizontal, except for the fact that notches 34 are provided in such position that each of the forward rollers 32 will drop thereinto when the seat 29 reaches approximately its forward extreme of adjustment.

To prevent inadvertent displacement of' the seats 29 by pulling them too far forward, and also to permit clamping each or all of the seats 29 in selected position, each seat is provided with a bolt 36 which extends rigidly downward therefrom through an elongated slot 37 in the associated horizontal board 17 of the frame 13. The length of these slots limits the extent of movement of the seats 29; and if it is desired to lock the seats in selected position the nuts 38, one of which is threaded onto each of the bolts 36 below the .board 17, may be tightened.

From the above described construction, it becomes apparent that the device of the present invention will be of utility in restaurants, ice-cream parlors, breakfast nooks, and similar installations where a rigidly positioned table is employed, and where permanently mounted seat. constructions are associated with the table or tables. WVhen employing the conventional type of seat constructions ditliculty was frequently encountered by persons getting into the seats, because of the relatively small space which is left between the table-and the seat constructions. If suiiicient space is left to permit facile ingress and egress to and from the seats, respectively, it is found that the seats are positioned so far from the edge of the table that considerable inconvenience results; and if the seat construction is positioned close enough to the table to permit persons to use the table comfortably when seated, difficulty is encountered in getting into and out of the seats. This disadvantage is overcome by means of the construction hereinabove described, because when the seats are not occupied they may be pushed back into retracted position, as illustrated upon the left handside of Fig. 2. This will permit a person to get into the seat very easily, whereupon he may easily pull the seat 29 forward until'its forward rollers 32 drop into their associated notches 34, whereupon it will be found that the occupant of the seat is positioned close enough to the table to use the table for any desired purpose with perfect comfort. When it is desired to leave the seat 29, the occupant has only to arise, and it will be found that the backs of his knees will strike the forward edge of the seat 29, causing the forward rollers 32 to be lifted out of the notches 34, and the entire seat 29 and the back .27 to be pushed back into retract-ed position.

A transversely extending partition 41 extends between the two end walls 6 and 7m such position that it limits the motion of the seats 29 and backs 27 when being retracted.

when one of the backs is pulled forward and the other is in retracted position.

If desired, a spring 43 may be so associated with each of the seats that whenever i an occupant of the seat rises, the spring will raise the forward edge of the seat sufliciently to remove the associated roller 32 from the notch. The seat 29 and its back 27 will then move to retracted position by gravity, because the after roller 32 of the seat rests upon the inclined surface 33.

It is to be understood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope of the appended claims.
