Description

Folding bed with pulling-up structure
Technical field
The invention belongs to bed, particularly a kind of folding bed with pulling-up structure.
Background technology
As shown in figure 16, known folding bed system is folded into the handstand V-shape, and uses cotton-wadded quilt or other beddings 1s put thereon and move freely.As shown in figure 15, known folding bed comprises halfbody 1a1,1a2 that is respectively bedding (mattress) 1s and the bed matrix 1g that is made of first and second framework 1d1, the 1d2 that have loading halfbody 1a1,1a2 loading frame respectively.First and second framework 1d1,1d2 outer end 1S1 set firmly respectively and are pivoted that first and second supports pin 1b1,1b2.The inner 1S2 of first and second framework 1d1,1d2 is connected with the connector 1f with middle foot 1e that uses connection.
First and second supports pin 1b1,1b2 system to form the mobile pin of tool castor 1k, and being hubbed at second of second framework 1d2 supports pin 1b2 to have castor 1k1, the 1k2 that is positioned at the forward and backward side of moving direction, therefore, support pin 1b1,1b2 folding by first and second toward approaching mutually direction, with form as shown in figure 16 be folded into the handstand V-shape together with bedding 1s.
On the other hand, because folding bed is a weighing body, make folding bed often form the strength of horizontal development because of the weight of folding bed and bedding, therefore, need the bigger manpower that up draws when folding, and must carry out being pulled to from deployed condition the operation of up drawing of the plumbness of handstand V-shape continuously, for weak tendency persons such as old men, its operation folding, that launch is comparatively difficult.
In order to remedy above-mentioned shortcoming, as shown in figure 15, under its horizontal development state, installing is the tension part 1w of tension spring respectively between the loading frame outer end 1S1 of the lower end of supporting pin 1e in the middle of the intermediate supports load-carrying and first and second framework 1d1,1d2, so that first and second framework 1d1,1d2 are produced pull-up moment.
But, as shown in Figure 12 and Figure 13, conventional construction is that the pull-up moment M1 hypothesis system of first and second framework of tension part 1w pull-up 1d1, the 1d2 of tension spring is when being set at certain value with the spring force of tension part 1w, and is α with first and second framework 1d1,1d2 loading frame from the angle initialization of level pull-up, the angle of inclination of tension part 1w and level is set at β (make downwards for just) during pull-up, and the loading frame length of first and second framework 1d1,1d2 is 1A.When middle support pin 1e keeps plumbness, but M1=TAsin (alpha+beta) (α is called folding angle) tried to achieve in summary.Moreover, support pin 1e system to keep vertical as previously mentioned in the middle of the installing tension part 1w, and the folding angle of the loading frame of first and second framework 1d1,1d2 is 0 ° of degree when level, be 90 ° when plumbness.
Is 0 °~90 ° angle with pull-up moment M1 with folding angle, utilizes mathematical expression to be calculated, and then forms dotted line as shown in figure 14.To between about 35 ° of degree, this pull-up moment M1 system is maintained at the numerical value of a certain degree to its folding angle from 0 ° (level); But near surpassing 35 ° along with near being folded into plumbness, because in fact tension part 1w forms parallel with loading frame, pull-up moment M1 reduces at leisure, and (alpha+beta) in fact become under the folded state of 0 ° (α=90 °, β=-90 °), its pull-up moment no better than 0.
Certainly, as previously mentioned, because folding bed produces the effect of gravity, therefore, at the initial stage from the deployed condition pull-up of level, it is maximum for folding negative moment system forms, and spring force T might not; Along with folding its tension part 1w length shortens and result that spring force reduces, in known tension part 1w structure,,, become and be necessary to use hand that loading frame is furthered particularly along with the increase of folding angle [alpha] though can improve the burden of hand in some degree.
Moreover, as shown in figure 16, for the pull-up moment M1 that makes spring remains under the less folded state, owing to crossing second vertical framework 1d2 under folded state, the castor 1k that makes the first support pin 1b is positioned at rear position etc., therefore, prevent any open necessity of first and second framework 1d1,1d2.Moreover its expansion this moment need make first to support the upper pulling force amount of the castor 1k of pin 1b1 by the loading frame below of second framework 1d2.
Moreover, in known folding bed,, pull-up part 1w is installed in the middle bottom of supporting pin 1e in order effectively to utilize the spring force of pull-up part 1w.Therefore, particularly from the side of folding bed except exist can see pull-up part 1w easily and be short of attractive in appearance, pull-up part 1w will become the shortcoming that barrier etc. must solve easily when sweeping.

Moreover, as shown in figure 11, also can parallel crank mechanism be set a side at the first loading frame 3A or the second loading frame 3B, the opposing party then forms the structure of second loading frame and the second support pin of known folding bed as shown in figure 15.
As Fig. 1, Fig. 2, shown in Figure 3, pulling-up structure 11 is to be installed on first and second loading frame 3A, the 3B of first and second framework 5A, 5B.As Fig. 3, Fig. 6, shown in Figure 7, pulling-up structure 11 comprises two pulleys 10 and pull-up part 14.Pulley 10 mat bearings are hubbed at the outer end 1S1 that is fixed on the last stiffener 21a of first and second loading frame 3A, 3B, and be positioned at first and second loading frame 3A, 3B under, i.e. higher position that can't be visual from bed matrix 9 sides.
Pull-up part 14 comprise an end fix or run through in the middle of support pin 7 protrusions 33 and be the elastic component 13 of helical spring or rubber etc. around being hung on the ropy 12 on the pulley 10 and being connected with respectively between ropy 12 two ends and first and second loading frame 3A, 3B.As shown in Figure 8, when pull-up part 14 be arranged at first and second loading frame 3A, when 3B is last, ropy 12 is through being fixed in eyebolt shape connecting piece 15 on the protrusion 33 by upper and lower with nut, to support the protrusion 33 of pin 7 in the middle of running through.Coiling one circle is fixed after also ropy 12 can being passed connecting piece 15 annular distances.
Owing to the protrusion 33 of an end winding of ropy 12 being supported pin 7 in the centre, the angle theta between ropy 12 and the middle support pin 7 is 30 °~60 ° under deployed condition, is preferably 40 °~55 °, and the best is 45 °.Moreover as shown in Figure 7, ropy 12 is a slot part by stiffener 21a at the elastic component 13 of the position combination by pulley 10 rears, therefore can be hidden and increases attractive in appearance.
As shown in figure 13, α, β value are set at value equal state with as shown in figure 12 known folding bed, and when the distance of 10 on the inner 1S2 side of first and second loading frame 3A, 3B and pulley is set at B, then pull-up moment M2=TBsin (alpha+beta); When folding angle [alpha] when slowly increasing to 90 ° of states for 0 ° of level, angle theta between ropy 12 and the middle support pin 7 becomes 0 °, be that β is 0 °, that is sin (alpha+beta) is near 1, its result system is shown in the solid line among Figure 14, along with the increase of folding angle, present its pull-up moment M2 also increases thereupon.
Moreover, so pull-up part 14 is except can being arranged at first and second loading frame 3A, 3B simultaneously, also can be separately set in the first loading frame 3A or the second loading frame 3B, promptly as shown in figure 11, when separately when the first loading frame 3A or the second loading frame 3B, one side are provided with parallel crank mechanism, pull-up part 14 can only be set in one side.
So, utilize pulling-up structure 11, not only can form bigger pull-up moment M2,, still can form bigger pull-up moment M2 even under folded state in the action initial stage with pulley 10.Therefore, can keep folded state really, optionally set elastic component 13 simultaneously, the manpower when folding to reduce, and can make folding operation more smooth and easy.Moreover the elongation of elastic component 13 between also can launching, fold by the selection reduction is to reduce the cost of elastic component 13.Moreover, because elastic component 13 length minimizings etc. also can be adopted the bigger elastic component of initial stage tension force 13,, form the strength of prior additional fold with under the folding bed deployed condition.
Therefore, as shown in Figure 4, in this enforcement state, the first loading frame 3A and first supports that setting can make first and second loading frame 3A, 3B remain on floating of level and prevent structure 16 near the articulated section of pin 4A.
As shown in Figure 4, float and prevent that structure 16 from comprising that the portion of running through 42 of running through group connecting part 26 on frame 21 21b of side frame portion and connecting piece 28 on every side runs through buckleing of location division 44 and end part 45 with being located at column sections 24a and reaching in the poroid location division 44 that constitutes with the portion of running through 42 concentric snap portion 43 under the deployed condition under deployed condition.Therefore, end part 45, can make first and second loading frame 3A, 3B remain on the deployed condition of level by inserting button.Moreover button ends part 45 and can give suitable hanging by hanging piece 46.
Moreover, float and prevent that structure 16 from also can be the various structures that can keep first and second loading frame 3A, 3B horizontal development state arbitrarily.And float and prevent structure 16, also can be arranged between the second loading frame 3B and the second support pin 4B except being arranged at the first loading frame 3A and first supports between the pin 4A; Also can be arranged at respectively simultaneously between first and second loading frame 3A, 3B and first and second support pin 4A, the 4B; Also can be first and second loading frame 3A, 3B and the middle not rotatable various structures of pin 7 formation of supporting.
As mentioned above,, can prevent that required pull-up moment is 0 when folding, therefore, can make folding operation more smooth and easy, improve its operability because the present invention has and pulley 10 is arranged in first and second loading frame 3A, the 3B and by the pulling-up structure 11 of pull-up part 14 pull-ups.
Moreover because pulling-up structure 11 is arranged in first and second loading frame 3A, the 3B, therefore can more easily set pull-up moment, and then and help improve folding operability.
Moreover, prevent structure 16 owing to possess floating of can preventing that deployed condition from floating, can increase the pull-up moment of pull-up part 14, therefore can reduce the manpower when folding.
Moreover, because formation and first and second loading frame 3A, the parallel parallel crank mechanism of 3B can make first and second support pin 4A, 4B, middle pin 7 travel directions of supporting to keep certain folding, therefore, when folding, make moving of first and second loading frame 3A, 3B more smooth and easy.
