Description
Technical field
The utility model relates to a kind of divans, and in particular to a kind of push-and-pull divan.
Background technique
With the variation of living environment, especially urban residence density is increasing, and people require consideration for how abundant benefit
With living space, so as to improve quality of life.Thus more and more people pay close attention to and need a kind of this common more function of divan
It can furniture.Divan can provide seat and the two kinds of functions that crouch according to user's needs, to provide in the space of relative compact more
Use function, and then make full use of living space, improve living quality.Common divan has collapsible and plug-type two
Kind, wherein plug-type divan usually has two layers or three layers of laminar stackable bed board, and passes through the guide rail and cunning between bed board
Wheel realizes conversion of the bed board between stratification position and expanded position.
However, the considerations of for convenient for structure design, existing plug-type divan muti-piece bed board on its stratification position
It is mutually superimposed, and after opening to expanded position, in order to enable bed board is generally in same level and then forms bed surface, usually
Whole bed surface height can depend on the minimum bed board in position, so that the height of entire bed is too low, influence use feeling.For
For three sections push and pull divan, the problem is especially prominent.And the cushion of existing push-and-pull divan is in folding position and expansion position
Height when setting is inconsistent, causes the usage experience of user bad.In addition, this existing plug-type divan needs complexity
Guide rail mechanism is unfavorable for transport and follow-up maintenance so that whole is bulky.
Utility model content
In order to overcome drawbacks described above existing in the prior art, the utility model proposes a kind of push-and-pull divan, packets
Support frame and push-pull mechanism are included, wherein support frame includes the back part being vertically arranged, and the back part has hollow cavity,
And support frame as described above supports the push-pull mechanism；The push-pull mechanism includes headrest portion and sofa seat frame, wherein headrest portion and institute
Stating sofa seat frame mutually can rotatedly connect, and the sofa seat frame is slidably fixed on support frame as described above, and feature exists
In the push-pull mechanism can change between folding position and expanded position, in which:
On the folding position, backrest of the sofa seat frame on horizontal position and close to support frame as described above, and
The relatively described horizontal position in headrest portion turns to overturn and be contained into the hollow cavity；
On the expanded position, the headrest portion and sofa seat frame are horizontally situated and abut one another, and institute
Height and its height on the folding position for stating sofa seat frame are roughly the same.
By this set, push-and-pull divan according to the present utility model has compact structure, and it is in expanded position
On, the extreme lower position of bed board is improved, so that cushion can be in identical height substantially on folding position and expanded position, especially
It is that height of the cushion of the push-and-pull divan of the utility model at folding position and expanded position is almost the same, so as to improve
The usage experience of user.
Based on the above technical solution, the utility model can also add one or more in following technical characteristic
It is a:
Further, the back part has L-shaped guide rail, and with a part of horizontally disposed, another part is substantially perpendicular

By its pulley by the rail guidance at being vertically upright incorporated in the hollow cavity.
Or as a kind of deformation, on the folding position, the headrest portion is opposite state sofa seat frame downwardly turn over into
Enter in the hollow cavity.
In this way, headrest portion can be easily accommodated in sofa backrest, so that overall structure is more compact.
Further, the push-pull mechanism further comprises tailstock portion, and the tailstock portion can be mutual with the sofa seat frame
It is slidably connected, and on the folding position, the sofa seat frame and the bed tail plate overlap each other simultaneously on horizontal position
Close to the backrest of support frame as described above；On the expanded position, the headrest portion, sofa seat frame and tailstock portion are located at horizontal position
It sets and abuts one another.Three-stage Bed having extensible part is thus formed, in order to provide more spacious developed area, provides more beds
Space of planes.
Further, it is further provided with link mechanism between the tailstock portion and the sofa seat frame, in order to described
Tailstock portion and the sofa seat frame generate during the push-pull mechanism can change between folding position and expanded position
The relative displacement of vertical direction.In this way, in the deployed position, tailstock portion and sofa sit frame left on upright position one section away from
From in order to which after sofa is sat on frame and places cushion, sofa sits frame and the upper surface in tailstock portion is substantially flush.
Further, the tailstock portion is provided with pulley foot in respective bottom end with the sofa seat frame, in order to
It is slided and is supported during the push-pull mechanism can change between folding position and expanded position, so that pushing away
It is pulled through Cheng Shunchang and laborsaving.
Further, support frame as described above main body is made of timber, such as solid wood board, sandwich plate etc..
Further, the sofa seat frame is provided with elastomeric element, and the elastomeric element can carry and be buffered in the sand
