FOLDING CHAIR.

Specification of Letters Patent.

Patented July 23, 1912.

To all whom it may concern:

fold down fiat on the chair when the latter is folded.

A further object of the invention is to provide a hood which is so connected with the back of the chair as to leave a space for ventilation.

A further object is to provide a chair of this sort with mosquito bars which can be used or not, as desired.

The invention has for further objects such other new and improved constructions in folding chairs as will be described in the following specification.

Referring to the drawingsFigure 1 is a front elevation of one construction of chair embodying my invention. Fig. 2 a rear elevation of the same. Fig. 3 apartial rear elevation on an enlarged scale. Fig. 4 a section taken on line 44 of Fig. 3. Fig. 5 a sec tion taken on line 55 of Fig. 1. Fig. 6 a side elevation of the chair. Fig. 7 an edge view of the chair and hood folded up. Fig. 8 a fragmentary side elevation taken on an enlarged scale in comparison with the View of Fig. 6. Fig. 9 is a side elevation of a modification illustrating a preferred construction. Fig. 10 is a sectional plan taken on line 10-10 of Fig. 9. Fig. 11 is a sectional view taken on line 1111 of Fig. 9, looking in the direction of the arrows. Fig. 12 is a side elevation of a different construction. Fig. 13 is a front view of the same, and Fig. 14 a side view showing the chair folded up.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring to Figs. 1 to 8 of the drawings, 10 represents the side pieces, and 11 the cross pieces or dowels of a frame to which pivoted another frame consisting of the side pieces 12 and the cross pieces 13, these two frames being secured together by the rivets 14 or other suitable means. Pivoted to the side pieces 10 by rivets 15 are the strlps 16 connected by a cross piece 17, the latter fit-tlng into one or other of the pairs of notches 18 on the side pieces 12. Braces 19 are pivoted by rivets 20 to the strips 16 and by rivets 21 to the strips 22, the latter belng secured to the side pieces 10 and 12 by the rivets 14. The braces 19 may be provided with the arm rests 23. The folding hood consists of the cover 24 supported on each side by the hoops 25 and 26 which terminate in the rings 27, through which passes a threaded bolt 28 provided with a wingnut 29. The back of the cover 24 is secured to the cross bar 30 of a frame, the ends of which 31 extend through the keepers 32, secured on the back of the side pieces 10. The rods 31 are prevented from slipping out of the keepers by the loops 33. The cover 24 may be provided with the curtains 34.

hen desired, mosquito bars 35 may be secured to the cover on either side. Preferably, these will be formed with the bindings 36, 37 on their lower and forward edges which will have the button-holes 38, the rear button-hole for the button 39 and the one at the forward corner for the bolt 28. The chair may also be provided with the forward mosquito bar 40 which may be provided with the binding 41 having the button-holes to go over the bolts 28. The wingnuts 29 will, of course, keep the mosquito bars from slipping off the bolts 28. The mosquito bar 40 may be rolled up to the position shown in the dotted lines andsecured by the tapes 42. Tapes 43 may be provided for holding the mosquito bars 35 rolled up, when desired. The hood may be tied down to the frame-work of the chair, in its folded position, by tapes 44. The bindings 36 of the mosquito bars 35'may be extended as shown at 45 and tied together hehind the chair, (Fig. 2). A strip of canvas 46 attached to the upper cross pieces 11 and 13 constitutes the seat and back of the chair. The chair may be folded up by first loosen ing the wing nuts 27 so as to fold the cover against the back of the chair. The cross piece 17 is then lifted out of the notch'es 18 and the frame consisting of strip 16 and cross piece 17 turned upwardly towardthe frame 10, 11. This movement folds the arms in alinement with frame 10, 11. The folding process is completed by folding the frame 12, 13 into alinement with the part above mentioned in the manner indicated in Fig. 7. If the wing-nuts 29 are un screwed, the hoops 25 can be folded back against the folded frame of the chair; and if made of proper length the hoops will not project beyond the end of the folded chair frame. The hood may be used or not, as desired. When not in use it will simply fold against the back of the chair, the upper portions of the hoop 25 coming against the cross piece 11 so that they do not incommode the person sitting in the chair. The attachment of the cover to the back of the chair is such as to permit the circulation of air between the hood and the back of the chair when desired. The space intervening be tween the back of the chair and the cover may be varied at will. hen the hood is pulled forward and the wing-nuts are tightened, the frame 80, 31, to which the back of the cover is secured, will be held at any desired position without the need of any other adjusting or holding devices, since the rods 31 will be put under some tension against the side pieces 10.

I prefer to provide my chair with the mosquito bars, such as are shown, but if desired, these might be dispensed with en tirely.

In Fig. 7 the chair is shown folded up, the mosquito bar in this instance being omitted.

In Figs. 9 to 11 inclusive, I have shownwhat I consider a more desirable construction. In these figures the chair proper is constructed in the same way except, instead of the wooden braces 19 of the preceding figures, the strips 16 are connected with the strips 22 by an iron or steel strap 47 to which is secured by the rivets 48 the wooden arm rests 49. The hood consists of a cover 50 which may be secured at the back to the back of the chair, in the manner above described, so as to provide for a. ventilation space, and of a hoop or hoops which support the forward portion of the cover. I have shown two hoops 51 and 52, the cover being preferably sewed or otherwise secured to these hoops, which preferably pivot upon the pivots l-Lt of the folding frames. The strips 2 are provided with engagements, for instance, the hooks 53, for the forward hoop 52. hen the chair is unfolded by causing one of the folding frames to be turned with respect to the other, the hooks 53 come into contact with the hoop 52 so that the hood is unfolded with the unfold.- ing of the chair. The hooks will obviously hold the hood in its unfolded or open posi tion. In the above description of the operation of the chair and hood, I have implied that the chair be unfolded to the full line position of Fig. 9 with the dowel. 17 in the upper pair of notches 18. If the chair is open to a more reclined position or if it is adjusted at any time to such position by setting the dowel 17 in any of the lower pairs of notches 18, it will be obvious that the hood will not be unfolded to or suspended in its fully unfolded position. If desired, the hood may be left in this position, or it may be drawn forward to its completely unfolded position and there held by the hooks or projections 54L, which are shown as being formed on the castings 55 secured to the arm rests 4:9. The hook 53 holds the hood in its extended position when the dowel 17 is in the upper pair of notches 18. T, therefore, provide three hooks 5% on each of the arm re ts to sustain the hood for the different positions of inclination of the chair made possible by the three other pairs of notches 18. It will be observed that supposing the chair to be in its ordinary, most nearly upright position, when it is folded up the back of the hook 54: will come against the hoop 52 so that the folding movement of the chair frames will fold the hood without the necessity of separate manipulation. This preferred form of my invention does away with the necessity of wing nuts employed in the other form of device to keep the hoops in their extended positions. As hoop 52 has some elasticity, the hood may be folded back against the back of the chair by springing the hoop over the hooks 53. I have not shown this construction of chair as provided with the mosquito bars, but obviously they might be employed if desirable.

In F igs. 12 to 14- inclusive, I have shown a chair of which the framework is made ontirely of metal and which is somewhat lighter and simpler in its make-up. This construction is designed particularly for chairs for children and for toy chairs, although a chair constructed after this fashion might be made sufficiently strong and heavy to adapt it for use by adults. Also in the constructions previously described, the parts of the framework might be made of metal instead of wood. Referring to Figs. 12 to 14, 56 is a three-sided. frame made preferably of a single strip of metal, between the ends of which is the rod 57. 58 is another three-sided metal frame, the ends of the strip of metal constituting the same, being connected by the rod The canvas strip 60 forming the seat and back of the chair is suspended between the rods 57 and 5.), the hood consists of a piece of canvas or cloth (31 secured at the back to the frame 58 and supported in front by the hoop (32 which is secured to the frames 56 and 58 by the rivets 63, by means of which these frames are pivoted together. lVires or rods 64 are pivotally connected with each side strip of the frame 58 and are formed with rings (35 extending around the hoops (32. Another rod or wire (36 is bent so as to form a three-sided fame and the ends of the rod or wire are pivoted to frame 58. The cross piece 67 of this frame rests in one of the pairs of notches 68 in the frame 56. The chair is shown folded up in Fig. 14.

I do not limit myself to the particular de vices, constructions and arrangements shown as modifications might be devised which would come within my invention as defined by the claims.

I claim:

1. The combination with a folding chair having a back which can be set at different inclinations and folding arms, of a folding hood comprising a cover attached to the back of the chair and a support for the forward edge of the same, and a series of engaging devices on said arms with which the cover support maybe engaged so that the hood is held open at different adjustments for different inclinations of the back of the chair.

2. A folding chair comprising a pair of pivoted frames, means for holding the same in extended position and at difierent angles to each other, folding arms, a seat supported by said frames; and a hood consisting of a cover secured at the back to one of said frames, a support pivoted to said frames below the arms and secured to the forward edge of said cover, and a plurality of engaging devices for said cover support arranged on said arm for the purpose specified.

3. In a folding chair, the combination with a folding framework comprising arms, means constituting a back and seat, a fold ing hood for the chair comprising a cover attached at the back to said framework, a

supporting hoop for the forward edge of the cover pivoted to the framework below said arms, and a plurality of hooks on each of said arms adapted to be engaged by said hoop so that the same may be held in different angular positions.

4. The combination with a folding chair consisting of a framework comprising a pair of pivoted frames, means for holding the same in an extended position, and means connected therewith providing a seat and back, of a hood for the same, a support for the front edge of the hood which is adapted to fold down against the chair, a frame to which the back edge of the hood is attached and which is slidably secured to the back of the chair so that a ventilation space is provided bet-ween the back of the chair and the hood which can be closed when desired, and means for holding said hood in its extended position.

5. A folding chair consisting of a framework comprising a pair of frames pivoted together, a strip of fabric constituting a back and seat suspended between said frames in combination with a hood comprising a cover secured at the back to one of said frames, a hoop to support the forward edge of the cover which hoop is foldable independently of said frames and hooks on the framework of the chair arranged so as to engage with said hoop and unfold the hood when the chair is unfolded.
