Description

Multipurpose electrically transformed sofa

The utility model relates to a kind of multi purpose sofa.

Along with improving constantly of people's level of consumption, the use of various sofas and divan more and more widely.Because house is narrower, when choosing sofa, people generally tend to the multi purpose sofa of energy double as bed usefulness.Therefore, the sofa majority of selling on the market is to use more.If carefully observe various multi purpose sofas on the market, be not difficult to find that they have following shortcoming:

(1), without exception, all need manual operation; Also need two people to operate simultaneously if be converted to the sofa of double bed.

(2), when commercially available multi purpose sofa uses as sofa, outward appearance or practicality are all better, but after being converted to bed, outward appearance is given passable sensation, because bedding needs special bin to deposit, it is also numerous and diverse to lay the bedding formality, uses inconvenient in the use.Opening the sofa that forms single bed with a popular seat together with handrail is example, because reasons in structure, bed length is not enough, and beddings such as pillow are easy to drop to the ground, and the people sleeps and has been difficult to comfort.Therefore, common people often do not do a usefulness to above multi purpose sofa, and only use when interim guest.

For overcoming the above problems, Japan Patent " real public clear 57-40840 " proposes the scheme that a kind of sofa is converted to double bed, but operation still is manual and harder to tackle.

The purpose of this utility model provides multi purpose sofa a kind of attractive in appearance, convenient, practical.It can be accomplished:

(1) electric operating is finished conversion, and the people need only be aided with a small amount of simple motion.

(2) no matter as sofa or as bed, all attractive in appearance, practical.It can become the daily bedding of general family.Promptly can furnish (promptly can replace bed) as sofa.Under the little situation of living space, the uneasy bed in room can increase usable floor area.

(3) carrying hutch can deposit bedding (bed clothes, sheet, pillow etc.) and lay the bedding process conveniently.

In the above each point, electric operating makes multi purpose sofa can adapt to the trend that people's purchasing power increases, and high-grade new product occurs.

Below do a narration with regard to structure of the present utility model and principle:

Fig. 1 is the profile of multi purpose sofa folding when becoming sofa, and Fig. 2 is the outward appearance when expanding into divan.The process that sofa is opened for bed is: by cushion " 6 " translation forward, two flitches " 1 " and " 2 " (this flitch also can be other strip components) of driving the sofa front lower place are divided into axle rotation becoming bedside with its end, simultaneously cushion " 6 " drags backrest " 8 " and falls down gradually and be threaded at the end at flitch " 1 " and " 2 ", expose the hutch of ensconcing under the cushion, after in case, taking out bedding, the cushion of putting above the cushion " 6 " " 7 " (three) is moved to hutch cover.Sheet box " 10 " just complete operation again falls down.If have a rest by reading in bed, can be as Fig. 2, handrail " 9 " taken off hang over the head of a bed and just can.

The folding principle of multi purpose sofa can be by Fig. 3 and Fig. 5 explanation.The frame structure of having drawn sofa among Fig. 3.Flitch " a 1 " end and the hinge joint of sofa body can be rotated, and the other end has connected flitch " 3 ".Flitch " 3 " is spreading flitch " 1 " when folding is sofa, makes that the sofa front is unlikely to lack one, and flitch " 3 " can turn over 180 degree when being opened for bed.Utilize the π shape iron on its top to block the pin of cushion " 6 " bottom, bed is not shaken.Flitch " 2 " is at the internal layer of " 1 ", and its end and sofa body link.When cushion " 6 " outwards translation then flitch " 1 " and " 2 " rotate along the direction of arrow among Fig. 3.In order to make rotary resistance little, under " 1 " and " 2 " roller is housed all.

Because the two of the mutual alignment of flitch " 1 " and " 2 " and rotation mode decision be Unscrew synchronously.If because of the two begin simultaneously to change and rotating speed identical, then flitch " 1 " must block " 2 ".The scheme that Fig. 5 has drawn and addressed this problem.On the base plate of cushion " 6 ", fixing an elongate slot that constitutes by iron plate.Fixing pin on flitch " 2 " end (being the pin " 15 " among Fig. 4) can slide in groove; Simultaneously also have an elongate slot on flitch " 1 ", the fixing pin on cushion " 6 " base plate (being Fig. 4 pin " 14 ") can slide therein.Under such structure, outwards during translation, flitch " 1 " revolves this flitch " 2 " soon cushion " 6 " and " 1 " and " 2 " can not block mutually.

When moving to position shown in Figure 5 outside the cushion " 6 ", two pins have all slided into the slit termination, and at this moment should there be inside gradient flitch " 1 " and " 2 ", so as during folding cushion " 6 " when inwardly moving resistance littler.

Above process can adopt manually and finish, and promptly is used for direct push-and-pull cushion " 6 ", also can be electronic.The electrically operated theory structure that drawn among Fig. 4, motor among the figure " 11 " is by counter pulley " 12 " the back driven gear " 13 " that slows down, and the tooth bar engagement at this gear and cushion " 6 " middle part drives it and moves backward forward.Should illustrate: the example that draws among the figure is gear, the tooth bar of having simplified.Gear can be pressed into as diagram shape, and tooth bar can replace with the band steel punching.Whole motor drive mechanism is contained in the case of hutch middle part.

The problem that may occur in the electric operating process is: backrest " 8 " is pulled out with cushion " 6 " and is arrived gear " 13 " when locating, and backrest " 8 " can not mesh the hole of its back tooth bar with gear " 13 " owing to also being in obliquity.This can add spring in the bearing lower end of gear " 13 " makes gear " 13 " that one section operating range upwards be arranged, and gear can be moved up and down with the fluctuation up and down of tooth bar, guarantees to close

One slotted hole is arranged at backrest among Fig. 4 " 8 " bottom, and this is in order to make behind the backrest fold-down and Mei You Inter crack and establishing between the cushion " 6 ".There is a sheet box " 10 " the backrest back among Fig. 4, and its effect has two, one, adorns sheet with it, sheet is built up strip packs into, and a head-clamp of sheet on the clip of box " 10 " bottom, the other end is exposed at outside the box, pulls out when making the bed, easily; The 2nd, revolve to turn 90 degrees afterwards and form bed surface with " 7 ", " 8 ", " 9 " (as shown in Figure 2).Because it just in time is the following position of pillow, so need not be soft.

Cushion " 6 " and backrest " 8 " all makes base plate and foam pad is separable.Like this, can take down foam pad during summer and become plank sofa and bed.Cushion " 7 " is not established base plate.When adopting plank bed, need the suitable bed hedgehopping of the cover plate of storage tank is formed bed surface.

Explanation to Figure of description:

Fig. 1 is the stereogram of electronic multi purpose sofa folding state.

Fig. 2 is the stereogram that this sofa is made the bed user mode.Handrail has been placed on the head of a bed among this figure.Also adoptable another program is: the handrail upper half part is outwards fallen down to do head of a bed shelf, place desk lamp etc.Fig. 3 is that " 4 " are hutch among the sofa frame figure that removes behind each cushion, storage boxboard, electric structure, sheet box, the handrail, the guide block when regain for backrest " 5 ", and its effect is to make backrest can raise the arrival precalculated position smoothly.The open position of " 1 " and " 2 " is represented in double dot dash line among the figure.

Fig. 4 is the side view of multi purpose sofa, and Local C is amplified.State when double dot dash line has represented that each several part is opened into bed among the figure.

Fig. 5 is the vertical view of multi purpose sofa.Flitch " 1 " and " 2 " are depicted as the situation of opening.With drawn groove under the base plate of cushion " 6 " of double dot dash line, pin position.
