Description
Technical field
The invention belongs to sofa technical field, it is related to adjustable in a kind of back frame, particularly a kind of function sofa
Detachable back frame.
Background technology
Sofa is a kind of chair equipped with cushion, can be single seat or multiple seats, equipped with spring or thickness
There is handrail on the chair of foamed plastics etc., both sides, are one kind of software furniture.With the development of sofa industry, sofa is in people
Important role is play in life, people's custom is sitting in sofa during amusement and recreation.With the continuous improvement of people's living standards,
Requirement of the people to furniture also more and more higher, it is common and the single sofa of function gradually will be given up by people.
In order that the function of sofa more perfects, regulation performance is more flexible, can carry out the something or somebody to fall back in sofa and backrest
It is separately provided, it is adjusted respectively and stretches out displacement and its reset.At present, the installation for something or somebody to fall back on and backrest on framework, is also present
Problems, such as 1, the size of framework can not adjust, cause it by certain limitation；2nd, framework is not allowed quick detachable, leads
Cause its processing difficulties, transport difficult.
So, for those skilled in the art, it need the installation frame to something or somebody to fall back on of the prior art and backrest
It is improved, to solve the above problems, the installation frame in sofa is not only adjusted its size, make its application more
Greatly；Can also be easily disassembled, facilitate the processing and transport of each parts.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that adjustable in a kind of function sofa
Detachable something or somebody to fall back on and back frame, the technical problems to be solved by the invention are how to realize the regulation and dismounting of framework.
The purpose of the present invention can be realized by following technical proposal：Adjustable detachable frame in function sofa, bag
The upper frame bar of the lower moulding for the shape that takes the shape of the letter U and the shape that takes the shape of the letter U is included, lower be provided between moulding and upper frame bar can adjust the tune of frame size
Save and something or somebody to fall back on travel(l)ing rests and movable backrest support are respectively equipped with mechanism, described lower moulding, something or somebody to fall back on travel(l)ing rests are in backrest
The top of travel(l)ing rest, described something or somebody to fall back on travel(l)ing rests are arranged on lower moulding by articulated structure one, described movable backrest
Support is arranged on lower moulding by articulated structure two.
Adjustable detachable frame in this function sofa, in the presence of governor motion, can suitably adjust lower moulding
Spacing between upper frame bar, so as to adjust the size of framework, makes its application wider；In the effect of something or somebody to fall back on travel(l)ing rests
Under, the something or somebody to fall back in sofa can be installed, and something or somebody to fall back on opposing frames is rotated, and also its motion has independence；In backrest
In the presence of travel(l)ing rest, the backrest in sofa can be installed, and backrest opposing frame is rotated, and its motion has
Independence.
Described governor motion includes some mounting holes one being opened on lower moulding two ends and is opened in upper frame bar two ends
