Description
Technical field
The present invention relates to technical field of furniture, specifically a kind of chair foot rest device.
Background technology
Sitting, into the animation of modern.According to authoritative media report, sitting does not only result in organ damage, muscle
Degenerate, also injure the heart, backbone, brain and enteron aisle.In order to change or mitigate the harm that the sitting of sitting race is brought, people
A kind of method for attempting be that increase is lain or the additional function of semi-lying on chair.Such as：
1) by the chair back, seat support and chair leg composition, seat support front end passes through " chair " of Application No. 2013101261451
Spring hinge is connected with an adjustable plate, and chair leg end is connected with roller, and roller can be turned up, and plate can pass through in outside plate two
Side slideway drawing structure carries out pull.Under the functional conditions that chair meets general folding seat, it can also enter as needed
The length adjustment of row chair, in addition, the roller that can be turned up makes chair to fix also slidably, show a variety of make
With function and state.
2) Patent No. ZL 2013205688201 " a kind of chair frame structure ", its chair base frame, rotation connection
In described chair base frame one end footrest rack, the governor motion for deploying or collapsing the footrest rack, the regulation machine
Structure include two pin-joint pieces for being rotationally connected with the chair base frame both sides respectively, be rotationally connected with two it is described be hinged
Push rod, one end between piece be rotationally connected with the pin-joint piece other end be rotationally connected with the footrest rack connecting rod,
The push rod is acted on so that the pin-joint piece can relatively rotate the first drive mechanism in the chair base frame；
Rotated between the pin-joint piece and the chair base frame where rotation connection between axle, the pin-joint piece and the push rod
Place axle is connected, there is spacing between two axles.Footrest rack of the present invention can be adjusted individually, only need to make the first driving machine
Structure acts, therefore simple to operate and laborsaving.
3) Patent No.：ZL 2014203983344 " a kind of footrest rack suitable for chair ", including support bar,
Toe board, the slide being slidably socketed with the support bar；The slide includes seat shell, positioned at the support bar outer wall
Ball between the seat shell inwall, it is socketed on outside the support bar and fixed cover is located in the seat shell and had
For the balladeur train for the through hole for limiting the ball position；The balladeur train section is square, and by structure it is consistent first
Halfbody engages with the second halfbody to be formed；The utility model support bar has with slide slides smoothness well.
4) " the chair foot rest device " of Application No. 201510760200.1 is by connecting seat assembly, three bar assemblies, leg rest
Component and positioning component composition.The parallel-crank mechanism of connecting seat assembly and three bar assemblies composition, passes through main operation
Handle makes upward-downward translation before and after footrest component work, and operates location hook by secondary operation handle and be located at chair most
Anterior or chair lower rear portion.
Above-mentioned first, second be to solve or mitigate sitting harm from the angle of overall chair, adds and lies or semi-lying
Additional function, but it is complicated, it is troublesome in poeration.3rd is solved or subtracts from a kind of angle of chair leg rest annex
Light sitting harm, and the chair back coordinate, and adding chair can lie or the additional function of semi-lying, practical, can be in original chair
Increase its additional function on the basis of son.But this " footrest rack of chair " pull out, it is more original to promote
Operation, can not substantially be sitting on chair and carry out；Its leg rest Board position can only be arranged below the opening position of seat support,
It is not very convenient to install.4th has substantially solved the defects of above-mentioned several, but there is also deficiency：1. when handle is put
When sole is designed to be positioned on link, fixation of the toe board on extreme higher position is relatively difficult；2. due to master
Operation handle and secondary operation handle are located off seat support bottom remotely, and the operation that is seated wants cat waist, awkward；3. put
Sole will be positioned and be fixed two kinds of alternating one-handed performances of toe board when highest or extreme lower position, operation
Need comparison block, precisely.Therefore, this technical scheme, using above having limitation and deficiency.
The content of the invention

Pass through said structure；A kind of chair foot rest device has following two operating methods.
1) operating method of embodiment one：
Rearmost position at toe board 4 under chair.People is sitting on chair, rotates counterclockwise main operation handle 1/2, is turned
Dynamic main operation handle 1/2 drives vertical member 2,/2/,3/3 1 behind rear connectors 2/3/1 and left back vertical member 1/2/3/3, the right side
Rise and rotate, overcame the elastic force of gas spring 1/2/2 before this, after be under the drive together of the elastic force of gas spring 1/2/2, make
Parallel-crank mechanism forward upward is to motion.Movement characteristic based on parallel-crank mechanism, make the level of translation
Part 4/3 and toe board 4 move up to extreme higher position, and are positioned by gas spring 1/2/2.Secondary behaviour before rotating counterclockwise
Make handle 1/4/2, the open slot I 1/1/5/2 of stay hook 1/5/2 is buckled into and is fixed on behind the right side on vertical member 2/2/3/3
Small fix bar 6/3, toe board 4 are fixed on the highest position before chair.Secondary operation handle 1/4/2 before rotating clockwise,
Stay hook 1/5/2 disengages small fix bar 6/3, releases the fixation to toe board 4, rotates clockwise main operation handle 1/2,
Main operation handle 1/2 overcame the elastic force of gas spring 1/2/2 before this, after be under the drive together of the elastic force of gas spring 1/2/2,
Make toe board 4 backward at moved beneath to the rearmost position of chair, and positioned by gas spring 1/2/2.To ensure to fix
Hook 1/5/2 and small fix bar 6/3 are in correct position before buckling into, and there is provided extension spring 1/6/2.
2) operating method of embodiment two：
This operating method and not existing together for aforesaid operations method only exist：Before toe board 4 is positioned at chair by gas spring 1/2/2
Behind extreme higher position, rear secondary operation handle 2/4/2 is rotated counterclockwise, buckles into the open slot II 1/2/5/2 of stretching bar 2/5/2
The flat shape section parts of front connector 1/3/1.The front connector 1/3/1 buckled into can not rotate.The quilt of toe board 4
The front connector 1/3/1 that can not be rotated is fixed on the highest position before chair.Rear secondary operation handle is rotated clockwise, is supportted
Tight bar 2/5/2 departs from front connector 1/3/1, and front connector 1/3/1 is recovered to rotate, and releases the fixation to toe board 4.
The torsion spring 1/7/2 being arranged between main operation handle 1/2 and rear secondary operation handle 2/4/2, makes stretching bar 2/5/2 lean on all the time
Nearby connector 1/3/1, it is easy to buckle into front connector 1/3/1.
In summary, the present invention implements the improvement to " the chair foot rest device " of Application No. 201510760200.1
And lifting, eliminate it and using upper limitation and deficiency, lamps structure is simple, reliable, practicality.Toe board exists
The positioning of highest and its lowest position is completed by same elastic component assembly/gas spring group, and toe board is in highest position
Fixation completed by fixture, people is sitting on chair and operated, convenient, reliable, comfortable, and the chair back coordinate, become sit
Appearance adds additional function, can be conveniently located on new design chair or original chair to lie or semi-lying, can be very
Solves or mitigates the harm that the sitting of sitting race is brought well.
