The specific embodiment

Below, the specific folding bed first embodiment combination form of the present invention is described.Please refer to Fig. 1, the 2nd, the present embodiment combination form has the folding bed that the automatic adjusting dependence seat function for sleeping in of the frame that crouches is sat in automatic adjusting dependence; Folding bed 1 (below, abbreviate as bed 1) be by the plane seem to be for First bedstead 5 of font and second bedstead 10 be its relative open side end state of subtend in addition, articulated and form by connecting material 20, but putting on this in the rough bedding 50 in the central portion bending of self length direction.What it was detailed is described as follows: first bedstead 5 is to have a pair of length direction pipe fitting 5a, the 5a that extends to the length direction of bed 1, and the width pipe fitting 5b that is extended between the end direction of this length direction pipe fitting 5a, 5a is

Glyph shape; Second bedstead 10 also has equally that the width pipe fitting 10b that end direction extended of a pair of length direction pipe fitting 10a, the 10a that extend to the length direction of bed 1 and this length direction pipe fitting 10a, 10a is

Glyph shape.

Near the length direction pipe fitting 5a and two bights that pipe fitting intersected of width pipe fitting 5b of first bedstead 5, distinctly stretch out downwards bed 1 from foot 6,6 that downside is supported.Front end in each foot 6 is provided with the length direction that leaves bedstead 5 and the castor portion material 8 that disposes two wheels 7,7.Also have by the bight that the length direction pipe fitting 10a and the width pipe fitting 10b two pipe fittings of second bedstead 10 intersect, distinctly stretch out downwards bed 1 from foot 11,11 that downside is supported.Front end in each foot 11 is provided with the length direction that leaves bedstead 10 and the castor portion material 13 that disposes two wheels 12,12, and through castor portion material 8,13, bed 1 is to move smoothly on face (outside the icon) is set.And, promptly because because each interval of the foot 11 of second bedstead 10 is narrower than each interval of the foot 6 of first bedstead 5, so, during the folding bed 1 that will illustrate in the back two castor portion materials 8,13 are touched mutually, and can make two bedsteads 5,10 near folding.

Two length direction pipe fitting 10a of two length direction pipe fitting 5a, 5a front end and second bedsteads 10 of first bedstead 5,10a front end then are connected material 20 via pin P1 use and are articulated.Again, the downside that connects material 20 be provided with opening downwards be approximately for

The midfoot 25 of font.Midfoot 25 is made of two vertical frame material 25b that extend downwards at the both ends that become between a pair of connection material 20 the horizontal pane material 25a that extends to width and this horizontal pane material 25a, and above-mentioned foot 6 and foot 11 are being supported two bedsteads 5,10 simultaneously from downside.

Also have, be provided with the automatic adjusting dependence seat frame 15 for sleeping in that becomes one and to reverse with this bedding 50 in the bedding 50 above first bedstead 5.Automatically regulating and leaning on seat frame 15 for sleeping in is in bedding 50, by the length direction pipe fitting 5a of first bedstead 5,5a is parallel and a pair of length direction pipe fitting 15a, the 15a that extend, the middle pipe fitting 15b that about central portion between two length direction pipe fitting 15a and these extend in parallel, linked as the end with above each pipe fitting, the first width pipe fitting 15c and the second width pipe fitting 15d that extend to the width of bed 1 are constituted.Length direction pipe fitting 15a, 15a do closely respectively at the inboard of the top of length direction pipe fitting 5a, the 5a of first bedstead 5 to connect, and first, second width pipe fitting 15c, 15d are positioned at each base end side (articulated section side) and front of first bedstead 5, regulate automatically to lean on that to sit the frame 15 that crouches be to have to be a day glyph shape approximately.

In the bedding 50 above first bedstead 5, and then be provided with near automatically regulating to lean on and sit the frame 15 that crouches and be approximately and be rectangular 51.This 51 be since the articulated section of two bedsteads 5,10 near, by the width pipe fitting 51a that extends to the width of bed 1,51a is from these both ends, at the length direction pipe fitting 5a of first bedstead 5, the upside of 5a, lean on to automatic adjusting respectively and sit the length direction pipe fitting 51b that frame 15 directions that crouch are extended, 51b constituted be approximately for Glyph shape, via the leading section of two length direction pipe fitting 51b, 51b then with state near the outside of regulating the leading section that leans on two length direction pipe fitting 15a, 15a sitting the frame 15 that crouches automatically, each leading section of two materials 51,15 is then articulated via pin P2, therefore to frame 51, should regulate automatically to lean on and sit the frame 15 that crouches and then become to do and reverse.

Describe in detail again to regulate automatically to lean on and sit the frame 15 that crouches, promptly this frame 15 is from the articulated section of two bedsteads 5,10 extreme direction before first bedstead 5, length with the length direction pipe fitting 5a of first bedstead 5, entering 1/3rd place approximately can reverse as the center of reversing, explanation is given in concrete adding, promptly be directed downwards to second bedstead 10 inclination decide angle and just can reverse.At the present embodiment combination form, though bedding 50 and automatic adjusting dependence are sat the frame 15 that crouches as one, can also sit on the frame 15 that crouches in automatic adjusting dependence and put bedding 50, the two is worked as other one, bedding 50 can also be started.

Again, automatically regulating the inboard that leans on middle the pipe fitting 15b that sits the frame 15 that crouches, be provided with the tabular arm 16 of long chi to the extension of second bedstead, 10 directions, the leading section 16a of this arm 16 is the place that is between the articulated section of pin P2 and two bedsteads 5,10 with the side.At the leading section 16a of arm 16, in about central portion of the width pipe fitting 10b of second bedstead 10, the one end is articulated via pin P3 by the other end 30b that dresses up the telescopic arm 30 that can reverse.Though do not add in detail and give figure and section out, but, telescopic arm 30 is electrodynamic type drives structure that are made of parts such as motor 35, output shaft, gear and wheel (indicate) and can moving, and relative advance and retreat are flexible by carrying out the sliding tubes 32 in the fixed outer cylinder 31.

By bed 1 from level (as shown in Figure 3), telescopic arm 30 makes it pull out elongation from fixed outer cylinder 31 as pulling out sliding tube 32, promptly automatically regulate lean on the inboard set arm 16 of sitting the frame 15 that crouches front end 16a can as to the left the below move and be pushed out, lean on seat frame 15 for sleeping in and bedding 50 and can become and start along with so then regulating automatically.Also have, otherwise, as from this state the fixed outer cylinder in telescopic arm 30 31 sliding tube 32 accommodated shunk, can become front end 16a being pulled as move the top to the right that makes automatic adjusting lean on the inboard set arm 16 of sitting frame 15 for sleeping in, make 1 of bed become answer and be original level.

Shown in Fig. 7,8, folding bed 100 (the following bed 100 that promptly slightly is called) at the second embodiment combination form, owing between first bedstead 5 and second bedstead 10, be provided with pipe 70 this point, with folding bed 1 its structure of the first embodiment combination form is different, and the formation beyond other is promptly all common with the folding bed 1 of the first embodiment combination form.At the present embodiment combination form,, be provided with another width pipe fitting 10c in two bedsteads, 5, the 10 articulated section sides of second bedstead 10.This width pipe fitting 10c is and parallel the extending of width pipe fitting 10b that the position on the next door of the telescopic arm 30 of side is provided with across an end of the pipe 70 of 5,10 of two bedsteads within it, supports the fixed part material 65 that it can reverse.The other end of pipe 70 is then supported to be fixed tool 75 in the inboard of first bedstead 5 via the pipe that will will do explanation in the back, with plane pipe 70 be crossed on telescopic arm 30 frequent become parallel state.

Pipe 70 is to extend to the direction of first bedstead 5, and with the side, this front end 70a stretches near the foot 6 of crossing arm 16 to first bedsteads 5.Then, the front end 70a of pipe 70 strides across between length direction pipe fitting 5a, the 5a of first bedstead 5, in position near width pipe fitting 5b, the inboard that adds the width pipe fitting 5c that gives setting again, though on figure, do not mark, only and the external diameter of pipe 70 be about identical length and separated two vertical component effect extending to downside and the lower end of two vertical component effects is connected to semicircle shape, the ring-type that is constituted by the semicircle support sector of the following lateral circle surface of support pipe 70.Then, 70 on pipe is when bed 100 is horizontal state, and its two ends promptly support tool 75 to be supported via the fixed part material 65 and first pipe and the face that is provided with (icon is outer) of bed 100 becomes the parastate of summary.

Again, shown in Fig. 7,9, lean on the inboard of sitting frame 15 for sleeping in automatic adjusting, it is moving to support second pipe support tool 76 of pipe 70 to be provided with the summary and first pipe support tool 75 same shapes and this support tool association.This second pipe supports that tool 76 is to lean between length direction pipe fitting 15a, the 15a that sits the frame 15 that crouches in automatic adjusting, be located at inboard near the 3rd set width pipe fitting 15e of the position of the second width pipe fitting 15d, see or bed is seen 100 the time in the back side when the front, be provided in a side of and first pipe is supported tool 75 position overlapped.This second pipe supports that tool 76 is to support tool 75 in abutting connection with part with first pipe, when bed 100 is level, promptly all irrelevant with pipe 70, but as the back to illustrate when telescopic arm 30 shrinks, the front end 70a meeting and first pipe of pipe 70 support tool 75 to roll over, therefore, also can become by second pipe and support tool 76 to support.But, when automatic adjusting dependence seat frame 15 for sleeping in starts, because first bedstead 5 and second bedstead 10 are to support level, so pipe 70 can not become automatic adjusting and lean on the obstruction that starts of sitting frame 15 for sleeping in.

For reaching the means of above-mentioned purpose and solution, the folding bed of being put down in writing 1 is that half first and second bedstead 5,10 frame of distinctly being supported from its downside of pact of bedding 50 are dressed up the state that is foldable to contrary V font; The arm 16 that prolongs to downside is equipped with in the inboard of this first bedstead 5, this arm 16 and this second bedstead 10 be by the movable book-slide telescopic arm of electrodynamic type drives structure 30 in addition frame connect, when this 1 is provided with face with it and becomes parallel level and rise, via shrinking this telescopic arm 30, promptly can be folded into against V-shape be feature to this bed 1.

Again, folding bed 1 is half first and second bedstead 5 supported respectively from its downside of pact with bedding 50,10 frames are dressed up the state that is foldable to contrary V font, this first bedstead 5 has with above-mentioned two bedsteads 5,10 articulated section side can be reversed as the center of reversing, side is provided with the automatic adjusting dependence seat frame 15 for sleeping in of the arm 16 that extends to downside within it, above-mentioned this arm 16 and this second bedstead 10 are in addition frame knots of the scalable telescopic arm 30 freely that moves by the electrodynamic type drives structure, above-mentioned bed 1 becomes parallel level to rise when with this face being set, via shortening this telescopic arm 30 is that 1 above-mentioned of folding bed is folded into contrary V-shape, leans on and sits the frame 15 that crouches and be feature by the above-mentioned automatic adjusting of can reversing of the above-mentioned telescopic arm 30 of elongation from above-mentioned level.

Again, folding bed 100 promptly also adds except the structure with above-mentioned folding bed of putting down in writing 1 at above-mentioned two bedsteads 5, between 10 the inboard, can not become position overlapped with above-mentioned telescopic arm 30 with the plane one pipe 70 is set, these pipe 70 one ends are the inboards that are articulated in second bedstead 10, the mat other end is located at first pipe of the inboard of first bedstead 5 and supports tool 75 with being supported of can rolling over, lean on the inboard of sitting the frame 15 that crouches in above-mentioned automatic adjusting, in the position of supporting that with side and above-mentioned first pipe tool 75 is adjacent, be provided with when above-mentioned level and regulate automatically and lean on when sitting the frame 15 that crouches and rotating, do not support second pipe of above-mentioned pipe 70 to support tool 76, in the time folding bed 100 will being folded into against V-shape, along with above-mentioned two bedsteads 5, each leading section of 10 will near the time, the other end of then above-mentioned pipe 70 and above-mentioned first pipe are supported tool 75 to roll over and are supported tool 76 directions to move to second pipe, the other end of above-mentioned pipe 70 promptly supports that by above-mentioned second pipe tool 76 is supported, it can be rolled over always, so, above-mentioned automatic adjusting dependence seat reversing of frame 15 for sleeping in can be controlled as its feature.

See also Fig. 2, after bed 1 becomes level, if when telescopic arm 30 being shunk (shown in Fig. 4,5), first bedstead 5 and second bedstead 10 must all form contrary V-shape again, by connecting part that material 20 will be articulated to each leading section of center such as close reversing.At this moment, the foot 6,11 that is contained in each bedstead promptly distinctly becomes and can reverse bedstead 5,10, folds so can become the state that touches the face of setting (on the figure show) as frequent wheel 7,12.When further telescopic arm 30 inwardly being shunk (as shown in Figure 6), between a pair of foot 6,6 of first bedstead 5, the a pair of foot 11,11 of second bedstead 10 can enter the state that becomes as being sandwiched, with the side, the leading section of each bedstead 5,10 each can be close, till becoming two castor portion materials 8,13 and overlapping (hap) mutually.

As top explanation, folding bed 1 in the present embodiment combination form, because can use the operation of electrodynamic type drives structure, make mat telescopic arm 30 simplyr to fold, so, folding operation needn't use staff to carry out, can be simple, and the more unable people of continued proportion also can be easy to carry out folding work.Further, be not only and do foldingly by a telescopic arm 30, can also automatically adjust and lean on to sit crouch, lean on and sit the structure that the frame that crouches reverses it so there is no need to be provided with in addition automatic adjusting.

Its less important Fig. 4 that sees also, the folding bed 100 of detailed explanation second embodiment of the present invention combination form.Shuo Ming the first embodiment combination form in the above, telescopic arm 30 is shunk (as shown in Figure 4) when carrying out folding bed 1, in the side, the flexible direction of telescopic arm 30 and pin P2 (frame 15 leans on the articulated section of sitting the frame 15 that crouches with automatic the adjusting) and pin P3 (the leading section 16a of arm 16 and the articulated section of telescopic arm 30) become after the state that is arranged as a straight line, though the strength that telescopic arm 30 is wanted to shrink can be clamped pin P3 and be passed to automatic adjusting and lean on and sit the frame 15 that crouches, because of meeting is that the center is regulated the frame 15 that lean on to sit crouches automatically and wanted the strength effect that starts as pin P2, so need sit the strength that the frame 15 that crouches wants to start according to regulating automatically to lean on staff etc.Because so,,, to describe for the folding bed 1 that can suppress the above-mentioned strength that starts along with stretching of telescopic arm 30 at this second embodiment combination form.Also have, in the second embodiment combination form, have with folding bed 1 identical portion's material of the first embodiment combination form and then use identical symbol.

The folding bed 1 of bed 100 and the first embodiment combination form is the same to be become by the electrodynamic type arm 30 that contracts and automatically adjusts to lean on to sit and crouch and fold.As shown in Figure 9, fixed outer cylinder 31 by self extending arm 30 will be pulled out sliding tube 32 and be extended, promptly be located at automatic adjusting lean on the front end 16a of the arm 16 of sitting frame 15 inboards of crouching can be as being pushed that move below to the left, lean on and sit frame 15 for sleeping in and bedding 50 starts along with this can become automatic adjusting.Also have, shrink as sliding tube 32 being accommodated by fixed outer cylinder 31 telescopic arm 30, promptly be located at automatic adjusting lean on the front end 16a of the arm 16 of sitting frame 15 inboards of crouching can be as being pulled that move top to the right, bed 100 becomes promptly that to reply be original level.

Again, as shown in figure 10, telescopic arm 30 will be shunk from the level of bed 100, promptly first bedstead 5 and second bedstead 10 must form contrary V-shape simultaneously, via connect material 20 with the part that articulated as the center, each leading section can as near reversing.Leading section by two bedsteads 5,10 is close, with level, only supported the leading section 70a of the pipe 70 that tool 75 is supported to move to leading section (left end among the figure) direction of first bedstead 5, also so then can become and be supported tool 76 to support by second pipe by first pipe.Flexible direction of (state shown in Figure 10) telescopic arm 30 and pin P2 (frame 51 leans on the articulated section of sitting the frame 15 that crouches with automatic the adjusting) and pin P3 (the leading section 16a of arm 16 and the articulated section of telescopic arm 30) are arranged as the state on the straight line, later i.e. folding with implantation 100, the leading section 70a of pipe 70 can support tool 75 roll over first pipe, and the leading section direction that becomes further to first bedstead 5 moves.

Then, though icon in addition not, by further shrinking telescopic arm 30, then the leading section 70a of pipe 70 can be more moves to the leading section direction of first bedstead 5, support the state that tool 76 is supported in supported the tool 75 and second pipe by first pipe, between a pair of castor portion material 8,8 of first bedstead 5, the a pair of castor portion material 13,13 of second bedstead 10 can become till the nipped state and enter, in the side leading section of each bedstead 5,10 can be adjacent to each other and become finish folding, till two foots 6,11 become overlap joint.

As described above, folding bed 100 at the present embodiment combination form, the telescopic arm 30 that moves via using the electrodynamic type drives structure can simply fold etc. beyond the folding bed 1 resulting effect of the first embodiment combination form, when bed 100 folding, by 70 frequent being supported of the pipe between two bedsteads by second pipe support tool 76, feasible adjusting automatically leans on reversing of seat frame 15 for sleeping in can be controlled, therefore, regulate dependence seat frame 15 for sleeping in automatically and do not have the phenomenon that starts.Thus, then there is no need to wait to do to push down automatic adjusting and lean on and sit the frame 15 that crouches the strength that will start is arranged, can obtain simpler effect of carrying out folding operation with staff.

Also have, the present invention is the restriction that is not subjected to above-mentioned two kinds of embodiment combination forms, can do various distortion.For example, lean on and sit the frame 15 that crouches, make it can do to automatically adjust to lean on to sit and crouch, can also use not have automatic adjusting and lean on to sit and crouch function and use telescopic arm 30 as above-listed explanation though the folding bed 100 of present embodiment combination form has automatic adjusting.At this moment, an arm 16 promptly is set with a fixing end 30b of telescopic arm 30 in the inboard of first bedstead 5.Also have, relevant folding bed 100 with automatic adjusting dependence seat function for sleeping in, it is regulated automatically to lean on and sits the frame 15 that crouches, be not restricted to day glyph shape as this case embodiment combination form, when being necessary to regulate dependence seat frame 15 for sleeping in and bedding 50 automatically as one, as long as the purpose of the corresponding high rigidization of energy, lightweight etc. also is provided with and can uses different shape.

And then the fixed position at telescopic arm 30 both ends, the fixed position at pipe 70 both ends are not restricted to the represented position of form of this enforcement, as long as can not do suitable change to folding just can not the obstruction, its quantity can also be changed.In addition, for preventing that the automatic structure of reversing of regulating dependence seat frame 15 for sleeping in is not restricted to the use pipe 70 as this case embodiment combination form.In addition, be located at the shape that automatic adjusting leans on the arm of sitting frame 15 inboards of crouching, also do not need shown in this case embodiment combination form, must be for extending to second bedstead, 10 directions.For example, as shown in figure 11, bed 101 is a horizontal state, leans on the inboard of sitting the frame 15 that crouches in automatic adjusting, and the arm 115 that extends as to vertical lower also can be set.At this moment, lean on the angle of reversing of sitting the frame 15 that crouches and to become lessly, the shape of arm 115 is become simply though certainly automatically regulate.

In sum, with of the present invention three big beneficial effects, details are as follows again:

1, folding bed 1 of the present invention, has the arm 16 that prolongs to downside in the inboard of first bedstead 5, this arm 16 is articulated by the movable book-slide telescopic arm 30 of electrodynamic type drives structure with this second bedstead 10, folding bed 1 is provided with face with it to be become parallel level and rises, and is that above-mentioned this bed 1 can be folded into against V-shape via shrinking above-mentioned this telescopic arm 30.So, only make the electrodynamic type drives structure action just can be simply and carry out the folding of bed easily, so can reduce very much the operation of use staff.

2, folding bed 1 of the present invention again, at first bedstead 5, two bedsteads 5,10 as the center of reversing it can be reversed with the articulated section side, the arm 16 that promptly extend downwards its inboard is provided with automatic adjusting and leans on seat frame 15 for sleeping in, the arm 16 and second bedstead 10 are that the book-slide telescopic arm 30 that moves by the electrodynamic type drives structure is articulated, become parallel level from the bed 1 and the face of setting, promptly be folded into contrary V-shape via shrinking telescopic arm 30, can make automatic adjusting dependence sit the frame 15 that crouches from level and reverse telescopic arm 30 elongations.So, then can also have, electronicly do the folding of bed because be to use, so folding operation is light very simply again by a telescopic arm 30 reversing folding with bed of frame 15 of lean on to sit crouching that automatically adjust.

3, also has folding bed 100 of the present invention, except having the above-mentioned the 1st, beyond 2 the effect, also have, at two bedsteads 5, between 10 inboard, be not provided with pipe 70 in not becoming position overlapped with the plane with telescopic arm 30, the inboard that is articulated in second bedstead 10 of these pipe 70 one ends, the other end promptly supports tool 75 with being supported of can rolling over by first pipe of the inboard that is located at first bedstead 5, lean on seat frame 15 inboards for sleeping in automatic adjusting, in the position of supporting that with side and above-mentioned first pipe tool 75 is adjacent, when being provided with level and automatically regulate to lean on to sit when the frame 15 that crouches reverses and do not support second pipe of pipe to support tool 76, in the time bed will being folded into against V-shape, along with above-mentioned two bedsteads 5, each leading section of 10 will near the time other end of pipe 70 and first pipe support tool 75 to roll over and move to second pipe support tool, 76 directions, the other end of pipe 70 promptly supports that via second pipe tool 76 makes it all support and can roll over, and it is controlled that so promptly automatic adjusting leans on the meeting of reversing of sitting the frame 15 that crouches.Carry out the bed folding the time, when with the flexible direction of side telescopic arm 30 and arm 16 pivoting point with telescopic arm 30, and the center of reversing of regulating dependence seat frame 15 for sleeping in automatically becomes after the state of arranging in a straight line, to bed is folded between the last contrary V-shape, because making automatic adjusting lean on to the shrinkage direction effect, telescopic arm 30 sits the strength that the frame 15 meeting generations of crouching will start, but, sit starting of the frame 15 that crouches so can prevent to regulate automatically to lean on because pipe 70 is supported tool 76 supporting by second pipe.
