The type drive link connects, should
Drive link horizon bar part cross-over connection relief angle steel bed frame, middle angle steel bedstead should
The type drive link is connected with the V-type drive link in middle angle steel bedstead district, this V-type drive link horizon bar part is parallel with middle angle steel bedstead, and be connected with middle angle steel bedstead in V-type drive link bottom, V-type drive link brace partly has straight type drive link to be connected with little slideway on the middle angle steel bedstead, for overcoming the dead point, also establish slideway on this straight type drive link, establishing connecting rod realization level between anterior angle steel bed frame and the middle angle steel bedstead is connected, this connecting rod and middle angle steel bedstead link are positioned at said straight type drive link slideway, and be connected with little slideway on the middle angle steel bedstead, medium-height trestle is connected with middle angle steel bedstead, and is provided with the medium-height trestle support bar and is connected with V-type drive link brace part end.Have connecting rod to realize that anterior angle steel bed frame, steel pipe front bedstead level connect, fore-stock is connected with the steel pipe front bedstead, have the fore-stock support bar to be connected with the steel pipe front bedstead, and link is positioned at the slideway on the steel pipe front bedstead.Establish a straight profiled bat with hook on the anterior angle steel bed frame, realize the angle of closing after folding.
Advantage of the present utility model not only may be folded in the sofa inside of any kind of form, also can be installed in the bottom of built-in wardrobe, to save the space in house.The utility model armchair of can packing into is a single bed, and the three-seater that packs into is a double bed, has to change flexibly, and the moulding selectivity is strong, characteristics such as applied range.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model flat expand state schematic diagram.
Fig. 2 is the utility model folded state schematic diagram.
Sofa frame among Fig. 1 (3), backrest (1), handrail (21), handrail underframe (26) are fixture, steel pipe front bedstead (18), anterior angle steel bed frame (17), middle angle steel bedstead (16) and relief angle steel bed frame level are linked in sequence, and with the support and connection of type support coupling bar (13) realization with backrest nexine support (27), set up 4 mattresses (4) separately on relief angle steel bed frame (15), middle angle steel bedstead (16), anterior angle steel bed frame (17) and the steel pipe front bedstead (18), and establish a sofa cushion (2) in steel pipe front bedstead (18) bottom, more than constitute the basic framework of bed.It supports and interlinked mechanism is such, said support is arranged along the bed both sides are relative with interlinked mechanism, type fixed support (14) is fixed on backrest nexine support (27) and the handrail underframe (26), establish big slideway (25), little slideway (28) on the middle angle steel bedstead (16), support link behind the obtuse angle type (11) is connected with type fixed support (14) horizon bar end, and go up big slideway (25) with middle angle steel bedstead (16) and be connected, there is spring (20) to be connected with support link (11) behind handrail underframe (26) and the obtuse angle type.Support coupling bar (13) and support link are drawn straight type drive link (12), this straight type drive link (12) with
Type drive link (10) connects, should
Type drive link (10) horizon bar part cross-over connection relief angle steel bed frame (15), middle angle steel bedstead (16) should
Type drive link (10) is connected with V-type drive link (9) in middle angle steel bedstead district, this V-type drive link (9) horizon bar part is parallel with middle angle steel bedstead (16), and be connected with middle angle steel bedstead (16) in V-type drive link (9) bottom, V-type drive link (9) brace partly has straight type drive link (8) to be connected with middle angle steel bed (16), establish slideway (19) on this straight type drive link (8), establishing connecting rod (23) realization level between anterior angle steel bed frame (17) and the middle angle steel bedstead (16) is connected, this connecting rod (23) is positioned at said straight type drive link (8) slideway (19) with middle angle steel bedstead (16) link, and go up little slideway (28) with middle angle steel bedstead (16) and be connected, medium-height trestle (7) is connected with middle angle steel bedstead (16), and be provided with medium-height trestle support bar (7a) and be connected with V-type drive link (9) brace part end, there is connecting rod (22) to realize anterior angle steel bed frame (17), steel pipe front bedstead (18) level connects, fore-stock (5) is connected with steel pipe front bedstead (18), there is fore-stock support bar (5a) to be connected with steel pipe front bedstead (18), and link is positioned at the slideway (24) of steel pipe front bedstead (18), establish a straight profiled bat (6) on the steel pipe front bedstead (18), the folding hook of its end is realized the angle of closing after folding.
Introducing the utility model below realizes by the folding process of bed to sofa: under external force, support coupling bar (13) is upset upwards, drive coupled relief angle steel bed frame (15), straight type drive link (12) moves backward, and stand on the outer support of sofa frame (3), straight type drive link (12) drives
