Definitions
- the present invention relates to a folding seat.
- This chair has a base formed on each side by two branches of unequal length, articulated in X by a hinge axis.
- the larger branches are extended upwards and support the back, while the shorter branches support a seat.
- the seating of the seat is articulated, at its front part, at the free end of the short branches of the base and is wedged at its rear end on stops supported by the long branches. of the legs.
- An object of the invention is therefore to provide a folding seat whose backrest or seat are made of textile web which has the simplest structure and stripped possible.
- the invention essentially relates to a folding seat articulated between an unfolded position and a folded position comprising: - A large U-shaped foot formed by two large branches connected by a cross which supports at their free end a textile web forming a folder, a bar now parallel to the two large branches, - a small U-shaped foot formed by two small branches connected by a crosses, the small branches and the large branches being connected two by two by a trunnion, and
- a seat formed by two longitudinal members connected at their rear end by a cylindrical tube on which is stretched a textile web, characterized in that each of the longitudinal members receives a tab which has an end opening in which engages a pivot supported by the free end of each branch of the small foot and a second opening in which engages the end of a spring steel bar which exerts a load on each spar.
- the idea underlying the invention is therefore to provide a folding seat whose seat and backrest are textile (ie a material without mechanical strength) that does not have a hinge axis; this result is achieved through a spring steel bar which is bent between the sill forming rails.
- a spring steel bar is engaged in a non-circular bore made in each of the major branches at the textile web forming folders.
- the free end of the branches of the small foot has a crush which increases their inertia module.
- each spar has a groove in which the textile ply forming the seat is slidably engaged and each leg of the large foot has a groove in which the edges of the side of the textile ply forming the backrest are slidably engaged.
- This arrangement allows for a seat without asperity.
- the large foot and the small foot has an elliptical cross section.
- Figure 1 is a front view of a folding chair in the unfolded position
- FIG 2 is a sectional view along H-II of Figure 1
- Figure 3 is a side view of the chair in the folded position
- Figure 4 is a sectional view along IV-IV of Figure 2.
- This chair comprises conventionally a folder, a seat and a base.
- the base is composed of two feet articulated one on the other. It is a large U-shaped foot 2 formed by a metal tube of elliptical cross section bent at right angles at two points to form two large parallel branches 2a 2b connected by a cross member 2c. On the free end side of the large branches 2a 2b, they receive a textile web which forms the backrest 4 of the chair.
- each of the large branches 2a, 2b has a groove in which is engaged, by sliding, the textile web forming the back 4.
- a ring is sewn on each of the vertical edges of the sheet, which blocks it in each of the grooves.
- Caps 5 close off the free ends of the large branches.
- each of the branches 2a, 2b has an opening which receives the end of a rod 7 of spring steel. These openings are not circular to prevent the rod 7 pivots with respect to the branches 2a, 2b.
- the rod 7 serves not only to stiffen the chair but it also serves as a carrying handle of the chair.
- the small foot 3 has a structure similar to that of the large foot 2. It is, in fact, formed by a metal tube of elliptical cross section folded at right angles in two points to form two small branches 3a, 3b, connected by a cross member 3c.
- the connection of the big foot 2 on the small foot 3 is made by two pins 10 secured to the large feet 2a, 2b which enter into openings in the small foot 3a, 3b.
- Each pin 10 is located substantially in the middle of the small feet 3a, 3b and in the middle of the portion of the large feet 2a, 2b below the inflection.
- the last part of the chair is the seat which consists of two longitudinal members 1 2 connected at their rear ends by a cylindrical tube 1 3. It is noted that the cylindrical tube 1 3 protrudes on each side of the longitudinal members 1 2.
- each spar 1 2 has a groove in which the sheet is slidably engaged and its rear part, a strip of the ply is folded and sewn by imprisoning the cylindrical tube 1 3.
- the seat is only stiffened on three of its sides.
- the longitudinal members 12 are each equipped with a tab 16 welded in an oblique direction.
- each of the lugs 1 6 has two bores 18, 19.
- the end piercing 1 8 serves to receive a welded screw at the free end of the branches 3a, 3b forming the small foot 3.
- the articulation of the seat is achieved by engaging the screws present at each end of the branches 3a, 3b on the small foot 3 in the extreme holes of the legs 1 6. A nut completes the connection.
- the rear portion of the seat engages between the two branches 2a, 2b of the large foot 2, the cylindrical bar 13 coming on the outer face of the two branches 2a, 2b.
- the longitudinal members 1 2 bear on the bar 8.
- the essential element of the chair is then a bar 1 7 of spring steel, each end engages in the openings 1 9 of the legs 1 6.
- the chair has a structure that is visually extremely ventilated.
- the chair In the folded position as can be seen in Figure 3, the chair retains the advantages of a conventional folding chair, namely a very compact footprint.
- the seat could include armrests connected to the branches of the large foot 2 and the longitudinal members 17 of the seat which forms a deformable parallelogram to fold them when the seat is itself folded.
