Technical field
The utility model relates generally to the movement decoration man in the position of substantially sitting bearing user's body
Tool, movement decoration furniture include chaise longue, arm-chair, sofa, lovers' seat, composite furniture, cinema seat, conventional chair and tool
There is the chair of removable portions, these furniture are generally termed as " seat tool " herein；More specifically, the utility model more particularly to one
Kind mechanical extending device, in addition, the utility model further relates to the seat tool using such mechanical extending device.
Background technique
Existing on current market allows user to stretch footstool or stool couch forward relative to portions and backrest of swinging back backward
Layback seat tool.These existing seat tools usually provide three kinds of home positions: the curling position of the non-layback of standard；Extended position；
And backward position.In curling position, portions be in generally horizontal orientation and backrest be arranged to it is substantially upright.In addition, such as
Fruit seat tool includes the stool couch for being attached with mechanical device, then mechanical device folds so that stool couch does not stretch.In commonly referred to as TV
The extended position of the position (" TV "), stool couch are stretched to the front of portions, backrest at the same time, and cushion turns round 4 degree or so angles,
With guarantee seat tool occupant comfort watch TV；In backward position, backrest be positioned to backward from extended position with portions at
Obtuse angle relationship is for resting or sleep.
The seat tool of the various modern in industry such as chaise longue or sofa is suitable for providing above-mentioned adjustment function at present；Ratio at present
Seat tool opening is more generally controlled using spanner；But in order to expand the use scope of seat tool, the use for improving seat tool is comfortable
Degree is driven backrest, cushion and leg-placing plate with band by motor currently, many seat tools provide power adjustment herein in connection with motor
Dynamic backrest, cushion and leg-placing plate expansion are collapsed, to meet requirement.
Although many conventional chaise longues can be operated satisfactorily, furnitur manufacturers still constantly pursue to develop and improve
Chair frame and functional frame, so as to reduce system complexity, improve operation stationarity and occupant operating experience
With comfort.Such as a kind of mechanical extending device shown in FIG. 1；The mechanical extending device include be located at the left and right sides of pedestal 1 and
Leg-placing plate component 2, cushions support component 3 and the backrest module 4 that left and right is arranged in pairs, the cushions support component 3 include
In addition to this support connector A5 substantially parallel with pedestal 1 further includes medianly zygomorphic leg-placing plate control assembly, described
Leg-placing plate control assembly include first connecting rod 6, second connecting rod 7 and the driving spring 8 (being indicated with straight line) being obliquely installed,
