FOLDING CHAIR Filed Feb. 21, 1933 Ji5 ,7 f /5 M7 LZ/ZBO aJ'Zh Patented Mar. 6, 1934 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to folding chairs and more particularly to a folding chair adapted for outdoor use or the like.

An object of this invention is to provide a relatively simple foldable chair which is so constructed that it will readily fold into a small compact package so that it can be readily stored in a relatively small space.

Another object of this invention is to provide a chair of this type which embodies only two movable parts which are so connected together that the chair will be firmly held in operative position when the parts are unfolded.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:

Figure 1 is a detail front elevation of a chair constructed according to the preferred embodi ment of this invention.

Figure 2 is a detail side elevation of the chair in operative position.

Figure 3 is a plan view of the back of the chair with the seat and rear leg structure in folded position.

Figiu'e 4 is a similar view but showing the front of the chair.

Figure 5 is a detailed side elevation of the chair in folded or collapsed form.

Figure 6 is a sectional view taken on the line 66 of Figure 3, and showing the manner of locking the parts of the chair in collapsed or folded form.

Referring to the drawing wherein like numerals designate corresponding parts throughout the several views, the numeral 10 designates generally a back which is provided at the lower end thereof with a pair of legs 11 which are spaced apart a desired distance. The legs 11 are constructed integral with the back 10 and are each provided with a bracing or reinforcing member 13. A transversely extending bar 12 extends between the braces 13 adjacent the upper ends thereof and provides an elongated slot within which is slidably received a rear leg structure l4.

A seat 15 is integral with the rear leg structure 14 and the seat 15 has the opposite side edges thereof projecting beyond the marginal edges of the leg structure 14, as at 16, so as to provide a shoulder engageable against the forward face of the back 10 and prevent further rearward movement of the seat 15 within the slot provided between the bar 12' and the back 10. The seat 15 and the rear member 14 are integral one with another and in the present instance are constructed from a single board but, if desired, this seat structure 15 and the rear leg 14 may be constructed of laminated pieces of material suitably secured together. The bracing members 13 are provided with notches or cut out portions 17 on the inner edge thereof, and a pair of pivoted locking members 18 are secured to the lower face of the leg structure 14, one member 18 adjacent each side of the leg structure 14, and these locking members 18 have reduced notch engaging portions 19.

The locking members 18 not only look the leg and seat structures 14 and 15, respectively, in collapsed form as shown in Figures 3 to 6 inclusive, but also act as a means to prevent withdrawal of the leg and seat structures 14 and 15 from the back 10. The back 10 is provided with a pair of elongated slots 20 adjacent each marginal edge portion thereof so as not only to reduce the weight of the back, but also to permit the securing of cushioning elements or the like, if desired.

In the use of this chair, it is placed in operative position by sliding the leg structure 14 rearwardly between the bar 12 and the back 10 until the shoulder 16 engages against the lower end of the back 10. Further rearward movement of the leg and seat structures is thereby prevented and the seat 15 is held against rocking movement by engagement of the lower surface thereof with the upper edge of the bar 12 and by engagement of the upper surface thereof with the lower edge of the back 10. While the seat 15 is held against downward rocking movement, it may be freely moved toward the back 10 when it is desired to fold the chair, as shown in Figures 3 to 6 inclusive.

When it is desired to fold the chair, the seat 15 can be rocked toward the back 10 and slid or moved upwardly toward the top of the back 10 so that the locking members 18 will be opposite the notches 1'7. These locking members 18 can then be turned so that the reduced or tapered end portions 19 will engage in the notches 17 of the bracing members 13 and in this position, the leg and seat structures 14 and 15 and the back 10 are held against movement relative to each other.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is:

l. A folding chair comprising a back structure, a pair of front legs integral with the back and spaced apart, a bracing member for each leg secured to one face thereof, a bar extending between the bracing members and positioned in forward spaced relation to the front legs, a seat, and a rear leg structure integral with the seat extending between the bar and the lower edge of the back and shiftable from a collapsed position parallel with the back to an operative position angularly inclined to the back, each of said legs having confronting notches and a pair of pivoted locking members on said rear leg structure and engageable in a notch to hold the chair in collapsed position.

2. A folding chair comprising a back, a pair of legs integral with the back, a bracing member for each leg secured to the front face thereof, a bar extending between the bracing members and spaced from the lower edge of the back, a seat, a rear leg means integral with the seat and loosely disposed between the bar and the back, a pair of pivoted locking means carried by the rear leg means, said bracing members having confronting notches to receive a portion of the locking means to hold the chair in collapsed position with the seat and rear leg means parallel with the back.

3. A folding chair comprising two relatively fiat members, one of said members having a cut out end portion and the other of said members having one portion slidable through said out out portion, a bar extending transversely of said one member downwardly from the inner end of said out out portion to provide a slot through which said other member is slidable that portion of said other member extending rearwardly through the first member constituting a rear leg and the remaining portion of said other member constituting a seat, and means for holding the two members in folded position, said means including a pivoted member having a restricted end on said other flat member, said onemember having a notch in said out out portion to receive said restricted end of said pivoted member.
