Abstract

The utility model relates to a foldable chair bed, which comprises a seat plate on which chair legs are fixedly arranged, and a backrest. One end of the seat plate is connected with a first foldable plate through a first hinge. A square block is fixedly arranged in the middle of the other end of the seat plate. The other end of the seat plate is connected with one end of the backrest through a sliding groove device and a hinging device. The sliding groove device consists of a sliding groove and a sliding bar. The cylindrical bar body of the sliding bar is inserted into the sliding groove and is in clearance fit with the sliding groove. At the same time, the side protruding part of the sliding bar is embedded into a slot of the sliding groove. Tightening nuts are fixedly arranged at the two ends of the side protruding part which is exposed out of the slot. The sliding groove and the sliding bar slide to change the overall length of the sliding groove device. The other end of the backrest is connected with one end of a second foldable plate through two ends of a triangular connecting device. The other end of the second foldable plate is connected with a support through a second hinge. The utility model provides the foldable chair bed which is designed on the basis of a chair for office workers and has the beneficial effects that the foldable chair bed not only can be used for sitting but also can be used for lying and the occupied space is small.

Description

The folding seat bed

Technical field

The utility model relates to a kind of chair bed, the especially a kind of folding seat bed that can sit and can lie realized through folding mode.

Background technology

At present, known folding seat is usually gone on a journey easy to carry for people or narrow and small ground is convenient to deposit and designs in the space, utilizes articulated mounting to connect and the principle of leg-of-mutton stability, like the folding small stool of often seeing ON TRAINS; Folding bed has and the folding seat similar techniques, and rather well received in this colony of deskman, but narrow and small office space does not often have unnecessary space to place this bigger comparatively speaking folding bed except necessary chair.

Summary of the invention

Do not have the space to place the problem of folding seat bed in order to solve narrow and small office space, it is a folding seat bed that can either sit and can lie and take up space less of basic engineering that the utility model provides a kind of seat with the deskman.

The utility model solves the technical scheme that its technical problem adopted: a kind of folding seat bed; Comprise the seat board, the backrest that are fixed with the chair leg; Described seat board one end is connected with first folded sheet through first hinge, and the other end center fixed of seat board has square block, and the other end top of seat board is connected with backrest one end with articulated mounting through chute device; Described chute device is made up of chute and slide bar; The cylindrical body of rod of slide bar inserts chute and chute forms matched in clearance, and the pleurapophysis of slide bar embeds in the fluting of chute simultaneously, and the two ends that pleurapophysis exposes fluting are fixed with the tightening nut; Chute and slide bar change the overall length of chute device through sliding; The backrest other end is connected with second folded sheet, one end through three angle connecting device two ends, and the second folded sheet other end is connected with support through second hinge, and three angle connecting device lower ends are fixed with the pole that has plectane.

The beneficial effect of the utility model is, it is a folding seat bed that can either sit and can lie and take up space less of basic engineering that a kind of seat with the deskman is provided, and conveniently uses, cost is low.

The specific embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

By Fig. 1, shown in Figure 2, a kind of folding seat bed comprises the seat board 2, the backrest 10 that are fixed with the chair leg; Described seat board 2 one ends are connected with first folded sheet 1 through first hinge 13, can realize the rotation of 180 degree, and present two plates are in 0 degree state; The other end center fixed of seat board 2 has square block 4; The other end top of seat board (2) is connected with backrest 10 1 ends with articulated mounting 5 through chute device 3, also can realize the rotation of 180 degree, when launching seat board 2 with backrest 10; Square block 4 plays the effect of supporting seat board 2 and backrest 10, guarantees that maximum rotation value is 180 degree; Its effect is sat when the folding seat bed is in folded state; So the angle of seat board 2 and backrest 10 is answered >=90 degree, and when bearing the power of certain effect, also can keep this fixing angle, reach the purpose that can lean on; Chute device 3 can meet this requirement; Described chute device 3 is made up of chute 14 and slide bar 15, and the cylindrical body of rod of slide bar 15 inserts chute 14 and forms matched in clearance with chute 14, and the pleurapophysis of slide bar 15 embeds in the fluting of chute 14 simultaneously; The two ends that pleurapophysis exposes fluting are fixed with the tightening nut; Chute 14 changes the overall length of chute device 3 with slide bar 15 through sliding, and when the folding seat bed was in deployed condition, the fluting of chute device 3 was in maximum position place (concrete size look concrete the size of two connectors of chute and decide); Elected four locknuts of chute device 3 are tightened the purpose that can realize this fixed angle after reserving angle, supply people to rely on.Backrest 10 other ends are connected with second folded sheet, 7 one ends through three angle connecting devices, 8 two ends, and second folded sheet, 7 other ends are connected with support 6 through second hinge 12, and three angle connecting devices, 8 lower ends are fixed with the pole 9 that has plectane 11.

To shown in Figure 5, this moment, the utility model expanded into an easy lectulum by Fig. 3.First folded sheet 1, seat board 2, backrest 10, second folded sheet 7 all become 180 degree, and the exhibition angle between the pole 9 is 90 degree to the maximum, because the plectane on the pole 9 defines their continuation rotation, make them remain on place, maximum exhibition angle.Pole 9 is fixed together through riveted joint mode and three angle connecting devices 8; Prop up as support; An outstanding articulated mounting on the support 6 makes the rotation between the two remain on 0 to being slightly larger than between 90 degree; The supporting role to second folded sheet 7 is played for maximum (being slightly larger than 90 degree) in the exhibition angle when being in deployed condition.
