6 Claims.

The invention relates to folding stools or chairs, and particularly to the type of stool or chair which, when not in use, may be folded compactly so as to save room at a wall, table, bar or other place, and may be quickly and readily pulled out and unfolded into position and be used.

An important object of the invention is to construct a stool or chair which will conveniently fold forward under the overhang of a bar or counter top, under tables, show cases, work benches, and other structures, or fold backward against a wall, partition, or counter, in such a manner as to provide ample and convenient space for standing or walking when the stool or chair is not in use.

Qne of the important features of the invention is in having one pair of legs of the stool or chair fastened to the floor, bar, or other support, and moving the other pair of legs toward the first mentioned pair of legs to cause the stool or chair to be in a closely folded and compact position, and able to stand upright by itself, unaided, and without leaning against the wall, bar, or other support, and without. the liability of being knocked down or dropped back flat on the floor.

Another important feature of the invention is that the stool or chair when folded and arranged to stand uprightly against a wall, bar or other support, is substantially locked in that position and cannot be pulled out, unfolded and put into operative position when an attempt is made to move thestool or chair laterally.

The stool or chair is caused to be folded and locked, or unfolded and unlocked by the employment of various means, including the lunged joints, the stop and locking lugs, the seat plate, the proper length of the legs, and the lift and push, and the lift and pull movements. When one pair of legs of the stool or chair is secured in the hinged joint which in turn-is fastened to the floor, or a, fixture, a lift and push movement by grasping the back rest will cause the stool or chair to raise and fold in a perpendicular position against the bar or counter, or under the overhang thereof, under the table, or against the wall, the other pair of legs automatically folding in a parallel position with the first mentioned pairof legs and being of suflicient length as to enable them to rest against the floor when folded causing a locking in this position of the stool or chair sothat it cannot be pulled or laid down flat on the floor even though it is constructed with a hinged base,'and the lift and pull movement While in this position will automatically unlock, release and unfold the stool or chair out to the proper position-for regular use.

One of the objects of the invention is to set a pair of legs of the chair and the back rest substantially straight or perpendicular, allowing any desired back rest to be permanently attached, keeping the back rest in a perpendicular position at all times during the folding operation, and in this way the said legs, with the back rest permanently attached,are still in a perpendicular 10 position and out of the way after being folded.

It is an object of the invention to fasten one pair of legs of the stool or chair in a'stationary position closely adjacent the bar, counter, table base, booth partition or wall, or instead of fastening the pair of legs to the floor, it may be fastened, or attached, directly to the bar, counter, table base, booth partition or wall,a1lowing the stool or chair to fold conveniently and also allowing more space, passageway or room for transportatlon or walking.

Another feature of the stool or chair is that it is interchangeable for either counter, table or booth stoolsor chairs, but utilizesthe same folding features regardless of the heights required for the various sizes and heights of bars, counters, tables, booths, benches, etc;

The stool or chair of the inventionmay be made from various materials such as iron, aluminum, steel or other metals or it may be made of wood. It will also be obvious that the stool or chair may employ various types of stool or chair seats and backs.

The stool or chair of the invention, because of its special folding and unfolding features is particularly useful for bar rooms, beer parlors; restaurants, ice cream parlors, cafeterias, hotels, department stores, retail stores, banks, at book- 'keepers, engineers and draft'smens desks or tables, and in other places.

The invention will best be understood by reference to the accompanying drawings, wherein the structure of the invention and modifications are shown, it being understood that I do 'not limit myself to the exact construction shown and illustrated, but in the claims hereinafter set forth intend to cover all variations and modifications thereof.

The stool or chair shown in Figs. 1 to 5, both back 33.

plate 29.

inclusive, comprises the seat 25 which is supported by the front legs 26 and 21 which diverge from the seat and are secured to the front supporting plate 28, which in turn is secured to the floor.

The upper ends of the front legs 26 and 21 are secured to the supporting U-shaped seat plate 29. Rear legs 30 and 3| also have their upper ends secured to the U-shaped seat plate 29. The front and rear legs are braced by the pivoted brace plate 32. The back rest 33 is secured to the rear legs 30 and 3| by means of three spaced .rods or bolts 34, 35 and 36. The back rest 33 of the stool is provided with horizontal strengthening cross bars 31 and 31a and a vertical intermediate strengthening bar 38. The front legs 26 and 21 are provided with the lower foot rest 39 which also acts as a cross brace, and the upper cross brace 40. The rear legs 30 and 3| are provided with the lower cross brace 4| and the upper cross brace 42. e

. In the form of stool or chair shown the back braces 31 and 38 are formed integral with the I The front l-eg foot rest and brace 39 and brace 40, and the back leg braces 4| and 42 are integral with their respective front legs 26, 2'! and back legs 30, 3|. The cross brace 32, however, is doubly pivoted and is raised or lowered depending on the movement of the legs. The cross brace 32 is pivotally mounted on upper pivot rod 43 and lower pivot rod 44, the ends of which are permanently riveted in their respective legs. The end portions of the pivot rods 43 and 44 pass through the plurality of corner eyelets 45 of the brace 32.

Bolts 34, 35, and 36 which pass through the rear legs 30 and 3| and the depending ends 33a and 33b of the back and the cross bar 31a, are provided with protecting and strengthening sleeves 46, 41 and 48, which maintain the stool or chair back in spaced relation to the back legs. The bolts and sleeves are made of such lengths that the stool or chair back shall be in such spaced relation to the back legs that the user may sit on the seat with comfort. It will be noticed that there is a 3-point connection formed by the bolts and sleeves connecting the back legs with the back rest. It will also be noted that any form of back rest can be readily secured to the stool or chair by means of the bolts 34, 35 and 36.

The plate 28, to which the lower ends of the legs 26 and 21 are secured, is provided with the integral fastening lugs 49 and 50. Bolts and nuts 5| and 52 pass through apertures in the lugs 49 and 59 and the adjacent lower ends of the legs 26 and 21.. Stop and locking lugs 53 and 54 are also integrally formed in the plate 28, being placed in the rear portion of the plate 28. The plate 28 is secured, to. the floor by means of the bolts and nuts 55 and 56.

v The U-shaped seat plate 29 which connects the seat with the top portion of the legs 26, 21 and 30, 3| is secured to the under face of the seat frame 51. As more clearly shown in Fig. 4, the seat frame is formed with integral cross plates 58 and 59 which extend from the peripheral part of the seat frame 51.

At the intersectionof the cross plates 58 and 59 is the boss 60. Additional bosses or ribs 60a, 60b and 680 on the cross arms or plates 58 and 59 are formed to assist in supporting the U-shaped These additional bosses extend from 3116 central boss 60 and the plate 29 rests against for the purpose of illustration.

' The U-shaped seat plate 29, the upper end portions of the legs 26 and 21 and the cross brace 40 are apertured to receive the pivot rod 6|. The upper ends of the rear legs 38 and 3| and the rear portion of the U-shaped plate 29 are apertured to receive the pivot rod 62. A third or intermediate rod 63 extends through both sides of the U-shaped frame or plate 29and acts as a stop for the top ends of the front legs 26 and 21. The U-shaped plate 29 is secured by bolts and nuts 64, 65 and 66 which hold it firmly against the ribs of seat frame 51. The upper ends of the four legs are pivotally mounted on the pivot rods 6| and 62 secured and held in the downwardly extending ears of the seat plate 29.

By reference to Fig. 3 the operation of the stool or chair will be readily understood. In the lefthand portion of the figure, the bar or counter 61 is shown with the stool folded and placed close to its wall 68 as far as possible in view of the fastening of the support plate 28 and the stop and locking lug 54. In this figure the numerals I, 2 and 3 will be seen in various places to more clearly show the operation of the stool. Numerals I, I, I, I, indicate the lifting or raising movement of the various parts where the numerals appear, which movement is required in order to unlock the stool from its locked position as shown in the full lines of the figure.

Numerals 2, 2, indicate the backward pull movement of the rear legs when the stool is to be unfolded, and the uppermost numeral 3 in the figure indicates the movement of the unfolded seat. The lower numeral 3 indicates the movement of the brace 32 in the portion ofthe figure showing the completely unfolded stool shown in dotted lines.

When the stool or chair is in the folded position as shown in the left-hand portion of Fig. 3, it is counterbalanced and locked in such a way that with the aid of the support at the plate 28, and particularly with the assistance of the supporting and locking lugs 53 and 54, it will stand upright in position without assistance. The lower portion of the legs 30 and 3I touch the floor and the lower portion of the legs 26 and 21 are stopped by the locking lugs 53 and 54 in such a way that the whole stool cannot fall toward the bar or wall 68, or away from it. It is, of course, essential that the stool shall not tip over and rest against the bar wall 68 since it would mar the finish thereof, and, obviously, the stool or chair must not be permitted to fall and lie on the floor. It will therefore be seen that in order to release the folded stool or chair from its locked position to have it in unfolded position for use, it is first necessary to raise the back rest 33 carrying the legs 30 and 3I, a slight distance from the floor, thus releasing them and moving them along the are indicated by the numeral 2 in the left-hand portion of Fig. 3.

It will be understood that the distances indicated by the numerals I, I, I, I, are exaggerated The parts do not move as far as indicated in the figure, but they do move sufficiently to release them from the locked position. When the back of the stool or chair and the legs are moved on the pivots 62 and 6|, the seat 25 and the seat frame 51 assume a horizontal position as shown in the dotted lines in the right-hand portion of Fig. 3. The brace 32 pivoted on the pivot rods 43 and 44 assume the position also shown in the dotted line portion of the figure. After the stool is placed in the position indicated by the dotted lines in the righthand portion of Fig. 3,- it will be seen that the rear legs 30 and 3| are in a vertical position and that the back of the stool is also in a vertical position, and the front legs 26 and 21 are angularly disposed with relation to the rear legs; whereas in the full line illustration at the left-hand portion of the figure both the front and rear pairs of legs are in a vertical position with the back of the chair also in a vertical position.

The stool or chair which has been referred to 10 in the foregoing detailed description has relatively long legs 26, 21 and 30, 3| and is particularly adapted for use at a bar or relatively high counter, and for that reason requires the wide form of supporting plate 28 to take the diverging end portions of the legs of the stool. Foot rest 39 is required in this form of stool to enable the user to rest his feet thereon, since normally they are away from the floor for some distance.

In the form of stool or chair shown in Figs. 6, '1 and 8 substantially the same general construction of legs, back and U-shaped plate are used. The U-shaped plate 29, however, is placed directly against the bottom of the seat portion 25.

The seat does not have the frame 51, although it could be employed. The-front legs and the back legs are shortened to a considerable extent so that the stool or chair may be used at a relatively low counter or bar, or may be used at a table where the feet of the user may rest on the floor; therefore there is no foot rest between the legs 26 and 21 as is the case in the stool of Figs. 1, 2, and 3. Since the front legs 26 and 21 converge and are relatively narrower at their base, the foot supporting plate is different in construction from that of the plate 28, but the principle of operation involving both plates is the same.

The supporting plate 69 is formed with the integral lugs 10 and H through which the pivot rod 12 extends. The pivot rod not only extends through the lugs 18 and H but through the end portions of the front legs 26 and 21. The front legs 26 and 21 pivot in the support 69 in the same manner in which they pivot in the elongated plate 28 of the first mentioned stool. The operation of the stool of Figs. 6, '7 and 8 is identical with that of the stool of Figs. 1, 2 and 3.

In order to secure the lock and counterbalance relation of the parts of this stool or chair, it will be seen that the lower portion of the legs 26 and 21 move toward and away from the stop lug 13 in identically the same manner as they move toward and away from the stop lugs 53 and 54 as shown in Figs. 1, 2 and 3.

This relation of the ends of the legs 26 and 21 with the support 69 having the lugs 16, H and 13 is further shown in Figs. 6, 7 and 13 of the drawings; A detail of the floor support is shown in Fig. 12 of the drawings.

The wall form of support for the end portions of the'front legs, as distinguished from the support which is secured to the floor, is shown in Fig. 9. A wall plate 74 is attached to the bar wall 68 by means of the bolts 15 and 16. A right angled portion 11 formed integrally with the wall plate 14 extends therefrom near the floor. The end portions of the legs 26 and 21 are pivotally secured to the extending portion 11 by means of the pivot 18.

Detailed views of the form of bolts 34 and 36 70 and the sleeves 46 and 48 and their method of securing is shown in Figs. 10 and 11.

Referring to Figs. 14, 15 and 16, there is shown a table 19 with stools or chairs like that of Figs.

6, 7 and 8 placed around it, together with illustrations showing the details of connections of 'the table plate with the front legs of the stools. The table standard 88 is provided with the base 8| which has a plurality of supporting plates 82 secured thereto. As shown, there are supporting plates82 on each side of the table base 8 I. They are secured in the table base by any suitable means, as by screws. The front leg supports 89 are suitable secured, as by bolts, to the projecting portions of the plate 82. The same form of supporting plate with the pivot joints and lugs as shown in Figs. 12 and 13, are employed in this construction.

:It will be seen, as illustrated in Fig. 14, that the stools or chairs surrounding the table I8 are-each secured to a base plate 82, which in turn is permanently secured to the table base 8|, and that when the stools are in their folded condition they stand underneath the table top 83, and the table with the four stools attached thereto, as described above, may be bodily lifted and transported as a single unit from place to place as may be desired. This is a very important point in connection with the use and transportation of tables and stools in restaurants, dining rooms, bar rooms and the like.

With regard to the stool or chair as shown in Figs. 17 to 22, inclusive, the construction is similar in some respects to the stools and chairs heretofore described, but because the stool is adapted to be used in a different situation than the stools heretofore described, the floor support is secured to the lower end portion of the rear legs instead of the lower end portion of the front legs. This will be particularly noted in Fig. 17. This stool is especially well adapted for use in booths used in ice cream parlors, breakfast nooks and the like. Further modification with reference to a sliding feature is also shown in the stool illustrated in Figs. 17 to 22, inclusive.

In the stool or chair of Figs. 1'7 to 22 inclusive, the U-shaped seat plate 84 is identical with the U-shaped seat plate 29 of the stools heretofore referred to, but its position is reversed so that the front legs 85 and 88 are vertically disposed beneath the seat 81, and the rear legs 88 and 89 are angularly disposed with relation to the front legs 85 and 86 so that the pairs of legs are in the reverse position with respect to the seat from those in the stools heretofore referred to.

The pivot rods 98 and SI function in the same manner as the pivot rods BI and 62, and the stop rod 92 functions in the same manner as the stop rod 63 shown in Figs. 1 and 2. The leg brace 93 is pivotally secured at 94 to the front legs 85 and 86 and at 95 to the rear legs 88 and 89. The pivot pin 85 is longer, however, than the pivot pin 44 shown in Fig. 2. This pivot pin 85 being long, has ends which project beyond the rear legs 88 and 88 as at 96 and 91, to receive the lower end portions 98 and 98 of the stool back I88 as shown in detail in Fig. 22.

Another feature of difference between the stool or chair of Figs. 1'7 and 22 inclusive, from the ones heretofore described, is in the sliding feature associated with the seat and the stool back. The stool back I88 has secured to it the horizontal cross bar IIII and the horizontal cross bar I82..

Behind the vertical bar I83 is the slide bar I84. This bar I84 has inwardly extending securing and spacing portions at its top and bottom whereby a slide groove I85 is formed (see Fig. 1'7).

Extending from the slide bar I84 to a U-shaped support I88, which is secured to the U-shaped seat plate 84, are the pair of bars or plates III! and 188.- These plates I81 and 'I88are each securely and firmly riveted to the U-shaped support I 86. They are also provided withthe spacer bolt I89 and the fixed pin I I8. The fixed pin I I8 extends through both of the spaced bars I81 and in the slide-way I85 are moved upwardly toward the top of the slide-way I 85. The stool is then in the position illustrated in Fig. 18.

It will be obvious that a good fit of the top portions of the rear legs 88 and 89 against the stop pin 92 may be obtained by providing the shoulders or cut-outs III. The U-shaped support 84 is secured directly to the seat 8'! without the interposition of the seat frame, such as the seat frame 51, with its special construction as shown in Fig. 4.

It will be seen that when it is in its folded position the stool or chair may stand adjacent a wall or in a booth in a little different situation from the manner in Whichthe stools of Figs. 3 and 7 stand.

In other words, the stools are provided with the foot supports on either the front or the rear foot portions to enable them to be placed in the separated places to a channel or inverted U- shaped seat plate, a seat surmounting said plate,

astop rod, said stop rod extending from one side ofsaid U-shaped seat plate to the other side of said seat plate, a wide flat brace between said pairs of front and rear legs pivotally mounted at its corners to said pairs of front and rear legs, said stop rod and said wide fiat, brace acting to make said stool or chair more rigid and providing against lateral movement, and a back rest fastened tosaid pair of rear legs, said back rest being spacedfar enough from said seat to furnish a comfortable position to the user, said back rest being held in spaced relationship to said seat by sleeves mounted on three bolts arranged trinangularly.
