Abstract
Divan bed comprising an almost parallelepiped frame structure, a plurality of movable frames, each constrained and movable according to roto-translative motions from a closing to an opening position, wherein said frames in the closing position are sequentially folded one over the other, and in the opening position, are consecutively aligned, and a mechanism able to move said frames characterized in that the mechanism comprises at least one lever, hinged in the node between the frame (2), a headrest, and the adjacent frame (3). In this way, undesired closure of the divan bed cannot occur.
Description
Technical field
The present invention relates to a kind of divan and open-close mechanism.As everyone knows, divan comprises: a kind of frame structure that is bordering on parallelepiped, and it is configured for the inside receiving area that bedding are deposited; With a plurality of movable frames that combine.These frameworks are according to moving from the rotation-translational motion that is closed into open position.In closing position, framework closes up makes mattress be folded into many and leave the place that is formed by fixed structure in; At open position, movable frame is aimed at successively in described volume outside, and limits bed surface (rest surface).These motions are because the one or more mechanisms that are inserted between fixed structure and the movable frame become possibility.
Background technology
So far, developed all kinds of same mechanism, and many modern mechanisms are transformed into bed to sofa easily, and needn't take off any seat cushion with at least three movable frames.
The applicant has described and has applied for a kind of similar products in disclosures in Italian patent application BA01A000005.
Although technological progress to some extent, known application still show several shortcomings.The major limitation of known mechanisms is unexpected closed danger.In fact, when being in when making the bed the position, if the user takes a seat near Fig. 1 middle frame (2) and adjacent frame (3) hinged place between the two, closure bed will meet accident.
Summary of the invention
The present invention solves the technical problem of above discovery, because it is a kind of like this divan, this divan comprises: a kind of frame structure that is bordering on parallelepiped; A plurality of movable frames that combine, they are according to moving from the rotation-translational motion that is closed into open position, and wherein in closing position, described framework closes up in proper order, and at open position, aims at successively; And a kind of mechanism that moves described framework, it is characterized in that this mechanism comprises at least one lever, this lever is hinged on the framework (2) and the joint between the adjacent frame (3) of described head rest, descends to prevent above-mentioned joint.Solved the accidental closing of bed like this.
According to target thereafter, the present invention can be only just can mobile seat cushion by means of two auxiliary elements.
Described in addition mechanism has only one degree of freedom, and in motion once open and close, and need not take off seat cushion and back cushion (21) and (19).
These and other advantage will be in reference catalogue 1/2 and 2/2 be pointed out in the detailed description of the present invention of illustration, has wherein been finished demonstration of the present invention and non-limiting embodiment.
Description of drawings
The above-mentioned catalogue of reference:
Fig. 1 is illustrated in the divan structure of " making the bed " position;
Fig. 2 represents the axonometric(al) projection of same divan;
Three consecutive steps of Fig. 3,4 and 5 expression divan opening operations; At last,
Fig. 6 is illustrated in the framework detail drawing of " making the bed " position.
The specific embodiment
With reference to above illustration, because divan comprises at each/framework and with the driving mechanism between the afterframe, thereby above-mentioned purpose is reached.Described mechanism has synchronous utensil, and only once motion just can be shifted movable frame onto open position from closing position, and vice versa.
Divan (Fig. 2) is represented with numbering/mark (11), and fixed structure is represented with (7).Frame structure has the shape that is bordering on parallelepiped, and this shape is formed inner receiving area and is made up of several frameworks.In these frameworks, have at least one to play the effect that back cushion supports.Fixed structure (7) limits inner receiving area (14), and in this district, the movable frame that is bonded to each other closes up, and divan is transformed into the position of taking one's seat.Then, described movable frame can transform to open position (seeing the order Fig. 3,4 and 5) from closing position, as long as they are aimed at, forms the bed surface with (15) numbering.
This mechanism with (10) numbering comprises the synchronous utensil that is inserted between the movable frame, just moves on to open position (seeing the order among Fig. 3,4 and 5 equally) from closing position so that framework once moves, and vice versa.It comprises quadrilateral (quadrilateral) (16), quadrilateral (12) and quadrilateral (17).The lifting of described mechanism and the system that opens are made of quadrilateral (16) and (12) and the spring (not shown) that helps operating.Particularly, first keeps elastic device to be inserted between lever (6) and the lever (1), keeps elastic device and insert second between lever (1) and fixed structure (7).Described elastic device also can be arranged on those elements that are fastened to element (6), (2) and (7).Quadrilateral (12) provides the head rest (2) of a configuration, and in the configuration of taking one's seat, described head rest is vertical.Quadrilateral (16) is by means of being hinged to the remainder synchronization action that lever (8) on the fixed structure (7) and (9) make mechanism.As its a kind of replacement method, the lifting of described mechanism also can reach by two simple quadrilateral (not shown)s, and an end of each quadrilateral is hinged on the fixed structure (7), and the other end then is hinged on the framework (2).Two quadrilateral link together by lever, and this lever is synchronized with the movement them.Described quadrilateral limit framework (2) during opening, make progress from the bottom, at the period of contact vertical translation downward from the top.
At last as shown in Figure 6, the quadrilateral (17) that comprises lever (4), (5), segment lever (25) and segment lever (23) moves the sliding system of seat cushion (21).
Except that the conversion from the sofa to the bed, vice versa, and mechanism also designs and can finish specific track.According to this track, mechanism reaches and makes easy-operating height itself more than the ground, as seeing among Fig. 4.The advantage part of this new mechanism is (Fig. 1), and lever (1) is hinged on the joint (2 ') between headrest frame (2) and the central frame (3).From functional point of view, it has solved the accidental closing of bed.In fact, in known mechanisms, lever (1) is hinged on the headrest frame (2); Therefore, the articulated joint (2 ') between close headrest frame (2) of user and adjacent frame (3) is when sitting down, and closure will meet accident.Another advantage part of this mechanism is, just moves seat cushion (21) by two auxiliary elements.
Increase element (4) and (5) and constitute a kind of simple system based on articulated quadrilateral thing (17).This mechanism is characterised in that in addition, and lever (6) can have five holes (as among Fig. 1 embodiment), or has four holes, can directly arrive on the fixed structure (7) with bolted.Under the situation of five hole levers, lever (6) is hinged on lever (8) and (9), is rotated-translation.In four hole configurations, lever (6) is not rotation-translation, but rotates around the fixing point with respect to fixed structure (7).This means and save lever (8) and (9).
