Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
With reference to shown in Fig. 1 to Fig. 6, a kind of foldable handrail provided by the present invention, including firm banking 1, fold mechanism
With handrail body 3；Fold mechanism includes link assembly, the lock assembly for realizing locking control to link assembly；
Link assembly includes first connecting rod 21 and second connecting rod 22；First connecting rod 21 and second connecting rod 22 include two ends,
It is designated as first end and the second end；The first end of first connecting rod 21 and the first end of second connecting rod 22 are pivotally connected with firm banking 1, the
Second end of one connecting rod 21 and the second end of second connecting rod 22 are pivotally connected with handrail body 3；
When lock assembly is in lockup state, it is static that link assembly is relatively fixed base 1, now, first connecting rod 21 with
The combining structure body of the combining structure body of firm banking 1, second connecting rod 22 and firm banking 1 equivalent to trigone, due to
Triangle has good stability, and so allowing for the foldable handrail of the embodiment of the present invention has good stability；This
When, handrail body 3 is in lifting status；
When lock assembly is in released state, between link assembly and firm banking 1, link assembly and handrail body 3
Between can relatively rotate, be achieved in handrail body 3 be folded down.
Preferably, first connecting rod 21 be arranged in parallel with second connecting rod 22, and first connecting rod 21 is located at the lower section of second connecting rod 22；
Not only ease of assembly is so set, and first connecting rod 21, second connecting rod 22, firm banking 1 and handrail body 3 are formed
One quadrilateral structure, because quadrangle has unstability, when lock assembly is in released state, can facilitate handrail
The folding of body 3.
Preferably, the upper end of the first end of second connecting rod 22 and firm banking 1 is pivotally connected, the second end of second connecting rod 22 with
Handrail body 3 is pivotally connected close to the end of firm banking 1, can not only so be simplified the structure of foldable handrail, be made its structure tight
Gather, and be also convenient for its assembling.
Preferably, first connecting rod 21 is identical with the length of second connecting rod 22, can so cause first connecting rod 21, second to connect
The quadrilateral structure of bar 22, firm banking 1 and the formation of handrail body 3 is a parallelogram；
Second end of first connecting rod 21 and the articulated section of handrail body 3 and the second end of second connecting rod 22 and handrail body 3
Articulated section be located on same plumb line, can so cause handrail body 3 all the time in horizontally disposed state.
As shown in Figures 1 to 6, lock assembly is located at the articulated section of second connecting rod 22 and firm banking 1；Lock assembly includes
Ratchet 23, the screens element 24 that can be engaged and separate with the realization of ratchet 23；Ratchet 23 is fixed on firm banking 1, screens member
Part 24 is arranged on second connecting rod 22；When screens element 24 is engaged with ratchet 23, it is quiet that second connecting rod 22 is relatively fixed base 1
Only, now, can be the combining structure body of second connecting rod 22 and firm banking 1 as a constitutionally stable entirety, the structure is steady
Fixed entirety and first connecting rod 21, handrail body 3 constitute structure very stable class trigone；
When screens element 24 is separated with ratchet 23, second connecting rod 22 and first connecting rod 21 turn downwards around firm banking 1
Dynamic, handrail body 3 is driven during link assembly is rotated down also moves downward and realizes folding；By ratchet 23 with
Screens element 24, which cooperates, realizes the folding of handrail body 3, strong operability, experiences.
As shown in Figures 1 to 6, user operates for convenience, and lock assembly also includes being used for control card bit unit 24 and spine
Wheel 23 realizes the switch member 25 of engagement and separation, and switch member 25 is arranged in handrail body 3；When opening switch member 25, screens
Element 24 is separated with ratchet 23.Preferably, switch member 25 is by the engagement of the control card bit unit 24 of drag-line 27 and ratchet 23,
Drag-line 27 is arranged on the inside of second connecting rod 22, so can not only control the physical dimension of fold mechanism, makes implementation of the present invention
The compact conformation of the foldable handrail of example, and its good appearance can be ensured.
As shown in Figures 1 to 6, operate and improve Consumer's Experience to further facilitate user, it is preferable that lock assembly is also
Including back-moving spring 26, one end of back-moving spring 26 is fixed on second connecting rod 22, and the other end of back-moving spring 26 is fixed on card
On bit unit 24；Back-moving spring 26 applies the elastic force moved to the direction of ratchet 3 to screens element 24 all the time；It can thus make
When proper handrail body 3 is moved upwards by folded state, back-moving spring 26 can drive screens element 24 to move, so that screens is first
Part 24 is engaged with ratchet 23.
To cause foldable handrail compact conformation, the good appearance of the embodiment of the present invention, it may be preferable that the of second connecting rod 22
The end of one end is provided with inner chamber, and ratchet 23 is located in inner chamber.
Foldable handrail provided by the present invention may be used on various types of seats, such as all kinds of wheel-chairs, scooter
On seat, making the seat comprising the foldable handrail, not only stability is good and easy to operate, Consumer's Experience is good.
To sum up, foldable handrail of the invention and the seat comprising the foldable handrail, due to being in lock when lock assembly
Only during state, first connecting rod 21 and second connecting rod 22 are static with respect to firm banking 1, now, first connecting rod 21 and firm banking 1
Combining structure body, the combining structure body of second connecting rod 22 and firm banking 1 equivalent to trigone, because triangle has
Good stability, so allowing for the foldable handrail of the present invention and the seat comprising the foldable handrail has well surely
It is qualitative.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvement and replacement can also be made, these, which improve and replaced, also should
It is considered as protection scope of the present invention.
