Description

Sofa chair and bed

The utility model relates to the folding device that a kind of chaise longue exists, especially: energy seat, the beach chair that crouches, folds.

At present, known chaise longue and beach chair structure, its seat, backup plate and leg frame are worn screw with clamping plate type and are connected, handrail peace class iron card, and leg frame and seat, backup plate cross screw and connect, and handle handrail and realize that the backup plate ascending, descending reaches seat, the purpose of lying.But because the iron card sticks screw, the retractable backup plate all must improve handrail, makes the iron card break away from just activity of screw.

The purpose of this utility model is: provide a kind of cold day, hot day to be suitable for, rising leg frame is an office seating, reducing the leg frame is couch, set level backup plate, expanding sleeve base, backup plate frame, renovate seat, squab plate in the surface, cold day increases soft cover, cover, set up bracing frame and can work as bed, folding can directly be drawn close, seat, extremely clearly demarcated couch bed for sleeping in.

The purpose of this utility model is achieved in that bending pipes one framework of using greater than foreleg 24, base boring 33, peace leg wheel are used, framework mouth upper edge boring 32, foreleg 2 inserts framework 4 segmentations and bores the number hole, and the leg endoporus bolt screw of the selected height of frame aperture 32 alignings connects during lifting.Middle the establishing with seat board 6 bottoms of foreleg is connected O31, and foreleg upper end angle inserts the back leg elbow.Use bending pipes one framework 5, bottom hole 37, peace leg wheel usefulness, framework mouth upper edge boring 36 greater than back leg 3, back leg inserts the framework segmentation and bores the number hole, frame aperture 36 during lifting, aim at the leg endoporus of selected height, and the bolt screw connects, back leg and framework 5 are towards relative centre, if sliding tray 38, it is positioned at, and the leg frame opens, seat board slip fore-set is pacified sliding tray, and foreleg and seat board connecting hole 31 bolts are tightened up a screw, seat board maintains an equal level, length that folding can be drawn close and position.Elbow 21 is established in the back leg upper end, oral area 25 sealings, and the bottom is opened microscler mouthful 27, allows the foreleg upper end insert, horizontal boring 26, the bolt screw connects into frame with the front and back leg.The curved slide rail top dog 20 of band is established in the elbow upper end, by the connection of step cover cap, the activity of handrail step slide rail 24.It is several that seat board 6 is established straight pipe, allow several straight pipes less than seat board 6 connect right overhead or the seat board frame 7 of moulding is gone into from the place ahead straight cutting, connect right overhead with several tubing less than seat board frame 7 again or seat board frame 8 straight cuttings of the moulding grillage 7 of taking a seat, seat board 6 fronts are along boring 28, the number hole is bored at seat board frame 7 rear portions on one side, extend the latch maintenance fully, grillage is connected, seat board frame 8 is provided with identical, seat board frame 7,8 afterbodys are established a lug alive, and anti-slip is gone out, and the bottom is established O or sold 30 before the seat board frame 7, wait to face the U type the bracing frame top establish pin or O30 socket, seat board 6 rear portions are established loose-leaf system O40 and are connected with backup plate bolt screw, and the bottom is established O or sold 34, allow bracing frame 12 establish pin or O35 hitches collection, after seat board frame 7 is pulled out and is pressed screw retained hard with seat board 6 jacks, 28 latches or bolt, the bracing frame cover is established O or is sold 30 connection supports before inserting seat board frame 7, and seat board 6 back edges are established the shelves post 39 that slides, and peace is gone in back leg and framework 5 sliding trays 38, slide up and down with the seat board afterbody, not only having can't get out but also slided does not hinder.It is several that backup plate 9 is established straight pipe, allow several tubing connect right overhead or the backup plate frame 10 of moulding less than backup plate 9, insert backup plate 9 from the top, backup plate 9 upper edges boring 19, backup plate frame 10 afterbodys are established a little lug alive, the bottom is bored the number hole on one side, press jack 19 latches or bolt hard screw retained when elongating fully, backup plate frame 10 upper rear are established O or are sold 18, treat that bracing frame 11 tops establish pin or O18 socket and support, backup plate 9 back ofs the body are established O or are sold 17, allow bracing frame 11 establish pin or O16 hitches collection, backup plate 9 bottoms are established O40 and are established O40 bolt screw loose-leaf system with seat board 6 rear portions and be connected, and backup plate 9 middle parts are established O41 and are connected with handrail uropore 41 or 42 bolt screws.Seat board 6 front upper places establish C or O29 allow backing plate 14 that the two sides turns over usefulness right overhead establish O or the C29 hook connects, when seat board frame 7,8 shrank when seat, backing plate 14 was topped on 6 of seat boards, and elongation seat board frame 7,8 is when doss, backing plate 14 is renovated on the surface, and usefulness is turned on the two sides repeatedly.Backup plate 9 upper ends establish C or O43 allow backing plate 15 that the two sides turns over usefulness right overhead establish O or the C43 hook connects, shrink backup plate frame 10, backing plate 15 is from the teeth outwards topped, elongation backup plate frame 10, backing plate is renovated in the surface, its specification, is provided with by seat, backup plate frame length and width.After seat, backup plate connected, folding was flexible, and seat, backup plate face style are multiple, and materials are various, and appearance is decorated and divided: high, medium and low shelves, and soft or hard, or cover or cover equipment.Boring vertical core 22 treats 13 1 clips of board on one side at the handrail middle part, a perpendicular latch maintenance, handrail step slide rail 24 and space, step cover plate 23 interval, when step slide rail cover cap leg frame sliding track top dog 20, than reservation, by and the angle that crouches, sleeps, handrail is vertical with leg frame inner edge, retractable does not hinder, if handrail hole 41 and 42 is connected with backup plate 9 holes 41 bolt screws, the ascending, descending backup plate is realized seat, is crouched.During folding, the leg frame is drawn close, and handrail is high perpendicular, and top dog is exempted in the stressed gap that is buckled in slide rail and cover plate, central seats that directly face the stage formula one open seat, once closing folding drawing close, handle handrail and set level backup plate, pull out seat, backup plate frame, seat, squab plate are renovated in the surface, set up bracing frame, chair the bed.The seat of chair is high, draws high forward and backward leg, and selected height is with framework and socket endoporus latch is respectively aimed in leg hole 32 and 36 or bolt is pressed screw retained hard.It is high to reduce seat, takes out latch or screw, with forward and backward leg and framework cover jack, when assert height, aims at inside and outside hole latch or bolt and presses screw retained hard.The seat of chair is wide, seat is narrow, be double usefulness, the single chair of using, its seat board equates with the width of backup plate, forward and backward leg frame width equates and slightly is wider than seat, backup plate, make retractable without hindrance, the length for sleeping in of chair crouches short, and seat, backup plate frame stretch, the seat board front along the hole 28 and backup plate upper hole 19, is aimed at and established the hole latch in seat, the backup plate frame or bolt is pressed screw retained hard.

Because adopt such scheme, the rising leg is put up office seating, reduce leg and put up couch, handle the handrail adjustment seat, by, crouch, folding does not need to handle handrail can directly be finished, the central seats that directly face the stage formula, one can reach seat and folds once closing.Seat, backup plate frame sleeve pipe stretch, and regulate the long weak point that crouches that crouches, and usefulness is turned on seat, squab plate two sides repeatedly, and is simple and convenient, and the bracing frame that insert, cover connects is simple in structure, the board of clip and latch maintenance and the legs and feet runner or the ball of screw retained, and any peace is used.
