The specific embodiment

An embodiment with essential characteristic of the present invention is a kind of bed that is convertible into chair, and it is constructed referring to Fig. 1 to Fig. 4.Its bed comprises the fixed bed board 2 that is fixed on the bedstead, is hinged on the turned down bed board 1 of fixed bed board 2 inside edges by hinge 1-2, and the seat stand 3 that can turn down bed board 1 below.There are two armrests 5 in the groove that is hinged on edge the both sides that can turn down bed board 1.Respectively there is a gripper shoe 10-4 both sides of seat stand 3.These two gripper shoe 10-4 can support the both sides of the edge of the turned down bed board 1 after setting level, and can turn down bed board 1 and the smooth complete bed board of fixed bed board 2 formation so that make.Install mattress 16-1 and backing cushion 17 respectively on the two sides that can turn down bed board.Lay cushion 18 on the seat stand 3.Can turn down on the inside edge of bed board 1 a locating piece 1-1 is arranged.When can turning down bed board 1 when being dug layback state (about 105 °), this locating piece 1-1 can be stuck in behind the bed along on the limit configuration of wallboard 10-2, makes can turn down bed board 1 and no longer turn over.

The mattress 16-03 that is connected part that can turn down between the mattress 16-2 on mattress 16-1 and the fixed bed board 2 on the bed board 1 is the flexible body that can bend.

Can turn down locating piece 1-1 on the bed board 1 and can adopt the latch form to come temporary transient two-way locking, can turn down bed board 1 unsuitable revolution because of people's ancon is pressed in down to cause on the armrest 5 that turns over when avoiding unidirectional stop.

The support structure of bed also comprises tailstock wallboard 10-3.

As seen, this bed mode of operation in use that is convertible into chair is very simple.In use, should be placed on a common desk to this bed before.So, open, just form a comfortable chair in the only position of desk front as long as can turn down bed board.These characteristics are particularly suitable for the furniture layout in the cubicle.Even wide 1.5 meters, in long 2.5 meters the cubicle, also can possess a standard bed, a chair and a desk.Its concrete layout type is extremely shown in Figure 7 just as Fig. 5.

Fig. 8 to Figure 11 has showed a kind of more complicated embodiment.The structure of the bed of this scheme be increased on the basis of above-mentioned embodiment with bed after the head of a bed support 10-1 that joins along wallboard 10-2, and the table 6 that is installed in the scalable folding and unfolding below the fixedly table 7 on the head of a bed support 10-1.Can turn down bed board 1 adjusting angle mechanism 4 has been installed.The user can turn down bed board 1 by adjusting angle mechanism 4 and be positioned on the desirable elevation angle.

When placing computer monitor on the fixing table 7, the table 6 of scalable folding and unfolding just can be used as Keyboard supporting board.Compare with the simple embodiment that the general bigger conventional tables of aforesaid the sort of and volume matches, adopts this floor space generally to understand smaller, also more complete in appearance, more coordination with bed of the tables' structure that carries.

Figure 12 to Figure 15 introduction be on the basis of feature shown in Figure 8, increased the embodiment of double-layer structural.This double-deck bed was equivalent to mutually reverse overlapping combining of two beds shown in Figure 8.The structure of the bed of its lower floor is with shown in Figure 8 almost completely identical.

The tailstock wallboard 10-3-02 of upper strata bed, bed back are that bearing docks combination mutually with head of a bed support 10-1-01, the bed back of lower floor's bed along wallboard 10-2-01 and tailstock wallboard 10-3-01 respectively along wallboard 10-2-02 and head of a bed support 10-1-02.

There is a toe board 8 in seat stand 3-02 structure the place ahead of upper strata bed.Between the forward position of upper strata bed seat stand 3-02 and the toe board 8 and behind the seat stand 3-02 along and the fixed bed board 2-02 inward flange of upper strata bed between seal by dividing plate 9-1,9-2 respectively.Like this, the fixed bed board 2-02 of upper strata bed, seat stand 3-02, toe board 8 and aforementioned barriers 9-1,9-2 separate upper strata bed and lower floor's bed jointly mutually.

The toe board 8 that is in low level is positioned at the fixed bed board 2-01 top of the tailstock direction of lower floor's bed.Because this shorter space is positioned at the tailstock top of lower floor's bed, thereby, very little to the harmful effect that the normal use of lower floor's bed causes.

For safety, be provided with a baffle plate 14-1 in bed forward position, upper strata.

For allow the people of upper strata bed can be normally about, this programme in the arranged outside of the toe board 8 of upper strata bed ladder 11.Ladder 11 has backboard 12 behind.Be provided with the platform 13 that one deck can supply the people to stand on ladder 11 tops.Two baffle plate 14-2,14-3 that play the safety barrage effect are set respectively in the both sides of platform 13.In order to make full use of the space, below platform, the other also integrated storage cabinet 21 of ladder 11 sides constructs.The door-plate 21-1 of storage cabinet 21 is to external-open.

Consider the limitation in height of general indoor canopy, this programme makes the terrain clearance of platform 13 be lower than the terrain clearance of toe board 8.Like this, stand in people on the platform also can low weight loose ground bed, operation can turn down bed board 1-02, and going up or down stairway 11 up and down.When a people is sitting in can turn down on the chair that bed board 1-02 forms the time, the baffle plate 14-2 of platform 13 and platform edges can allow that still another person stands and leans on.

In the other position of seat armrest of seat, the top of in the inner part baffle plate 14-2, also be provided with the teapoy platform 19 of a band coaming plate 19-1.

On platform 13 liang of side shield 14-2,14-3, two handrails have been installed respectively, so that use during user's going up or down stairway.

The recommendation size numerical value of the main structure of this programme is as follows:

Bed board width: 0.8 meter

Bed board total length: 1.95 meters

The structure total length of bed direction: 2.4 meters (this length is compression further)

The bed board bottom surface terrain clearance of upper strata bed: 1.43 meters

Toe board 8 terrain clearances of upper strata bed: 0.99 meter

The bed board end face terrain clearance of lower floor's bed: 0.47 meter

Bed toe board 8 bottom surfaces, upper strata are apart from lower floor's bed bed board end face distance: 0.49 meter

Platform 13 terrain clearances: 0.72 meter

Platform 13 width: 0.4 meter

Platform 13 length: 0.87 meter

This double-deck bed that this programme is described is particularly suitable in universities and colleges' dormitory.In one 3 meters wide, 5 meters long common dorm room, can make up and place this double bed of 4 covers.Its outward appearance such as Figure 16, shown in Figure 17.As can be seen from Figure 17, because the double-deck bed of this two couple leans on indoor side walls oppositely to place respectively, thereby the structure to the outstanding terrace part in central gangway of each bed is interlaced, just forms the unobstructed well-to-do passage and the public space of S type.In 3 meters wide rooms, about 0.6 meter of the distance at the narrowest place of the passage between the bed of both sides (the baffle plate 14-2 on the platform 13 sides side of relative both sides bed, the distance between the 14-3 edge), about 1 meter of the widest part (making the bed along the spacing of baffle plate 14-1 apart from the opposite upper bed in platform 13 outers).As needs, can also above the tailstock of upper strata bed, locker be set.Also the toe-board of upper strata bed can be extended to ceiling, form the enclosure space of band door.

Obviously, compare with the eight-occupant apartment students' dormitory of 4 common double-deck beds of existing employing, the double-deck bed among Figure 13 can in the interior space of same area, provide better go to bed, the condition of daily life, study and use computer.
