Specific embodiment
A kind of height-adjustable handrail, is applied to bathroom field, such as so that handicapped crowd supports by toilet seat
Use.With reference to Fig. 1～Fig. 2, the handrail of an embodiment includes handrail body 1, motion bar 2, fixing pipe 3 and governor motion, lives
Lever 2 is fixed in handrail body 1 bottom, and governor motion is arranged inside fixing pipe 3, and motion bar 2 can be upper and lower by governor motion
With respect to fixing pipe 3, being matched with fixing pipe 3 of movement, thus move up and down that to realize handrail body 1 high by motion bar 2
The regulation of degree.Governor motion includes elevating lever 4, fixed mount 5 and ratchet 6.Elevating lever 4 is fixed in motion bar 2 bottom, fixed mount
5 is positioned at elevating lever 4 side and affixed with fixing pipe 3, and ratchet 6 is rotationally connected with fixed mount 5, and elevating lever 4 is near fixed mount 5
Side is provided with some draw-in grooves 41 along longitudinal arrangement.When lifting handrail body 1 is allowed to shifting, the center of gravity of ratchet 6 is near elevating lever 4
Side, is adjusted by the gear that height is realized in the cooperation of ratchet 6 and draw-in groove 41.
Specifically, with reference to Fig. 3～Fig. 7, ratchet 6 such as known ratchet, including circular or approximately round circular portion 61
And the pointed part 62 being formed by circular portion 61 evagination, its rotating shaft 7 is arranged in the middle part of circular portion 61, by rotating shaft 7
Connection with fixed mount 5 is realized it and is rotated connection.It is appreciated that the center of gravity of ratchet 6 is located at the close wedge angle of circular portion 61
At part 62.The center of gravity of ratchet 6 is near elevating lever 4 side, that is, pointed part 62 is near elevating lever 4.In lifting handrail body 1
When being allowed to shifting, elevating lever 4 with move, ratchet 6 slightly turns to deviating from elevating lever 4 direction under the promotion of elevating lever 4
Do not affect to move past journey thereon；When stopping lifting handrail body 1, in the presence of self gravitation, its pointed part 62 snaps in ratchet 6
Within the draw-in groove 41 of corresponding height, thus stoping elevating lever 4 from declining, handrail is maintained at the state of corresponding height.
With reference to Fig. 4～Fig. 6, the bottom evagination in draw-in groove side for the elevating lever 4 forms convex tendon 42.Ratchet 6 is provided with block 63, gear
Block 63 is located on the two sides of ratchet 6 circular portion 61 vertical rotation axial direction, and extends to rounded portions by the middle part of circular portion 61
Divide 61 edge.Ratchet 6 is additionally provided with gag lever post 64, gag lever post 64 on the pointed part 62 of ratchet, and in both sides edge respectively
The rotation of ratchet is axially extending.Fixed mount 5 is provided with limiting section 51 in deviating from elevating lever 4 side.With reference to Fig. 8 to Fig. 9, handrail body
When moving to limiting condition (i.e. extreme higher position) on 1, then lift handrail body 1 upwards, convex tendon 42 abuts block 63 and by promoting
Block 63 and then promote ratchet 6 to turn to the center of gravity of ratchet to deviate from elevating lever 4 side, and until gag lever post 64 abuts limiting section
51, its rotation amplitude is limited by the effect of gag lever post 64 and limiting section 51.In this case, the pointed part 62 of ratchet 6
Deviate from elevating lever 4, no interact with elevating lever 4 and its draw-in groove 41, handrail body 1 can be pushed to reduce height.
With reference to Fig. 4～Fig. 6, elevating lever 4 includes connecting portion 43 and the draw-in groove portion 44 cooperatively forming inverted L shape, wherein connecting portion
43 are adapted to the internal diameter of fixing pipe 3, and draw-in groove portion 44 is located under connecting portion 43, and narrower width, thus formed with fixing pipe 3 setting
Put gap.Fixed mount 5 is under connecting portion 43, and is provided with positioned at draw-in groove portion 44 between the side of draw-in groove and the setting of fixing pipe 3
In gap.The bottom surface fovea superior of connecting portion 43 forms the curved portions 431 making way for ratchet 6.Curved portions 431 away from draw-in groove portion one end with
Fixed mount 5 abuts, and fovea superior degree increases gradually near draw-in groove portion 44 direction.With reference to Figure 10～Figure 11, handrail body moves down
During to limiting condition (extreme lower position), the pointed part 62 of ratchet 6 abuts side with fixed mount 5, under continuation positioned at curved portions 431
Pressure, arcuately portion 431 turns to center of gravity and replys near draw-in groove portion 44 side ratchet 6, now lift again handrail can carry out aforementioned
Height adjust.
With reference to Fig. 1, the handrail of the present embodiment also includes a bushing 8, and bushing 8 adaptation is socketed within fixing pipe 3, above-mentioned tune
Section mechanism is arranged within bushing 8, and fixed mount 5 and fixing pipe 3 bottom are affixed by bolt, and fixed mount 5 is passed through with bushing 8 side
Pin is affixed, it is achieved thereby that being relatively fixed of bushing 8 and fixing pipe 3.From outward appearance, fixing pipe 3 outer wall non-bolt etc.
Connector, outward appearance is more succinct, additionally, steadiness also can be improved, isolation steam etc..
With reference to Fig. 1, handrail body 1 includes lid 11, armrest support 12 and handrail lower cover 13 on handrail, and armrest support 12 fills
It is connected to and cover between 11 and handrail lower cover 13 on handrail.Motion bar 2 is fixed on armrest support 12 bottom, and by armrest support 12 bottom
Extend downward under handrail lower cover 13.The shape adaptation of lid, armrest support and handrail lower cover on handrail, and pass through spiral shell with bottom
Tether and connect, on tailored appearance no interface, and handrail, lid can be provided with soft structures to increase the comfort level of use.
Above-described embodiment is only used for further illustrating a kind of height-adjustable handrail of the present invention, but the present invention not office
Be limited to embodiment, any simple modification that every technical spirit according to the present invention is made to above example, equivalent variations with
Modify, each fall within the protection domain of technical solution of the present invention.
