Withdrawal process, can only rely on motor switch withdrawal process to be stopped, if can not be closed by the switch of motor-driven mechanism in time
Closing, the problem that severed finger will occur, this will be breakneck for handicapped old man or child.As fruit product is made
Become life injury, not only jeopardize the safety of people, also the manufacturer of product can be caused huge compensation.
Summary of the invention
In view of existing multifunctional chair problem present in the foot-operated removal process, it is an object of the invention to provide one many
Function chair proof mechanism, it is to avoid bring injury during use.
To achieve the object of the present invention, a kind of multifunctional chair proof mechanism of the present invention includes pantograph linkage and electricity
Machine drive link mechanism, described motor drive link mechanism includes the first connecting rod being connected with motor and is connected with first connecting rod
Second connecting rod, described second connecting rod has block, when electrical power drive motor drive link mechanism travels forward, institute
State block to abut with the connecting rod of pantograph linkage, promote it to travel forward and drive whole pantograph linkage stretch forward by
The foot section of multifunctional chair is stretched out；When foot section is regained by needs, driven by motor motor drive link mechanism receding
Return, block disengages with the connecting rod of pantograph linkage, pantograph linkage under the action of gravity of foot section self to
Reclaim, arrive when reclaiming position, block and connecting rod against, foot section is fixed.
According to another object of the present invention, the present invention proposes a kind of multifunctional chair with proof mechanism, described multi-functional
Chair includes seat portion and telescopic foot section, and the bottom of described seat portion is provided with and drives foot section to stretch
Pantograph linkage and motor drive link mechanism, described motor drive link mechanism includes the first connecting rod being connected with motor
And the second connecting rod being connected with first connecting rod, described second connecting rod has block, when electrical power drive motor drives even
When linkage travels forward, described block abuts with the connecting rod of pantograph linkage, promotes it to travel forward and drives whole stretching
Contracting linkage stretches forward and foot section is stretched out；When foot section is regained by needs, driven by motor motor drive link
Mechanism retracts backward, and block disengages with the connecting rod of pantograph linkage, and pantograph linkage is at the weight of foot section self
To recovery under power effect, arrive when reclaiming position, block and connecting rod against, foot section is fixed.
The multifunctional chair proof mechanism of the present invention, only relies on the driving force of motor when the foot section of multifunctional chair stretches
Promote pantograph linkage to stretch forward, and when foot section is regained, only rely on the self gravitation of multifunctional chair foot section
To recovery, owing to the deadweight of multifunctional chair foot section is smaller, can the injury of people will be preferably minimized；Return in foot section
After receiving position, the block of motor drive link mechanism supports fixing work with pantograph linkage against providing foot section again
Rock with preventing it.
Accompanying drawing explanation
By detailed description below in conjunction with the accompanying drawings, the aforesaid objects, features and advantages with other of the present invention will become
Obviously.Wherein:
Fig. 1 show the driving structural representation that existing multifunctional chair foot section stretches and shrinks；
Fig. 2 A show the structural representation of the multifunctional chair proof mechanism extended configuration of the present invention；
Fig. 2 B show the view during the multifunctional chair proof mechanism withdrawal of the present invention；
Fig. 2 C show the structural representation of the multifunctional chair proof mechanism withdrawal completion status of the present invention.
Detailed description of the invention
In conjunction with the architectural feature of the accompanying drawing present invention and advantage, details are as follows.
The multifunctional chair proof mechanism of the present invention is for having the massage armchair of foot-operated Telescopic, leisure chaise longue etc., this many
Function chair generally comprises seat portion and the foot section that can stretch, and foot section is separate with seat portion, seat
Foot-operated pantograph linkage is installed and drives the motor drive link of described shrinking connecting-rod structure action under the chair frame of part
Mechanism, is driven shrinking connecting-rod structure action by motor drive link mechanism.
With reference to the structural representation of the multifunctional chair proof mechanism extended configuration of the one embodiment of the invention shown in Fig. 2 A,
Described multifunctional chair proof mechanism includes pantograph linkage 10 and motor drive link mechanism 30, described motor drive link
Mechanism 30 includes the first connecting rod 31 being connected with motor and the second connecting rod 32 being connected with first connecting rod 31, described second connecting rod
There is on 32 block 33, when electrical power drive motor drive link mechanism 30 travels forward, described block 33 with flexible even
The connecting rod 12 of linkage 10 abuts, and promotes it to travel forward and drives whole pantograph linkage 10 to stretch foot section forward
Stretch out and provide fixing to the foot section stretched out after foot section stretches and puts in place and support；See Fig. 2 B, when needs will be foot-operated
When part is regained, driven by motor motor drive link mechanism 30 retracts backward, and block 33 disengages with connecting rod 12, shrinking connecting-rod
Mechanism 10 under the self gravitation effect of foot section to recovery；See Fig. 2 C, when pantograph linkage 10 is in foot section
Deadweight is lower when arriving retrieving position, block 33 and connecting rod 12 again against, foot section is fixed, prevents foot section to be present
Rock under chair part.
The proof mechanism of the multifunctional chair of the present invention, realizes foot section with original motor-driven mechanism that fully relies on
Stretch different from withdrawal, only rely on when foot section stretches the driving force of motor to promote pantograph linkage to stretch forward, and
When foot section reclaims, motor-driven mechanism is disengaged with pantograph linkage, only rely on multifunctional chair foot section
Self gravitation to recovery, now, if accidentally having finger clamp in pantograph linkage, due to multifunctional chair foot section
Deadweight is little, and removal process can be stopped at once, will be preferably minimized the injury of people；After foot section reclaims and puts in place, motor
The block of drive link mechanism provides fixation to prevent it in seat portion with pantograph linkage against to foot section again
Rock below Fen.
The present invention also proposes a kind of multifunctional chair, and it includes seat portion and telescopic foot section, seat portion
Chair frame under foot-operated pantograph linkage is installed and drives the motor drive link mechanism of described shrinking connecting-rod structure action,
Described motor drive link mechanism includes the first connecting rod being connected with motor and the second connecting rod being connected with first connecting rod, described
There is on second connecting rod block, when electrical power drive motor drive link mechanism travels forward, described block with flexible even
The connecting rod of linkage abuts, and promotes it to travel forward and drives whole pantograph linkage to stretch forward and foot section is stretched out；
When foot section is regained by needs, driven by motor motor drive link mechanism retracts backward, block and pantograph linkage
Connecting rod disengages, and pantograph linkage to recovery, arrives when reclaiming position, block under the action of gravity of pedal part self
With connecting rod against, foot section is fixed.
The invention is not limited in described embodiment, those skilled in the art is in the spirit without departing from the present invention i.e. public affairs
In the range of opening, still can make some revise or change, therefore the scope of the present invention with claims limit in the range of
Accurate.
