Embodiment
A kind of height-adjustable handrail, applied to bathroom field, such as so that handicapped crowd supports by toilet seat
Use.With reference to 1~Fig. 2 of figure, the handrail of an embodiment includes handrail body 1, and motion bar 2, fixing pipe 3 and governor motion are living
Lever 2 is fixed in the bottom of handrail body 1, and governor motion is arranged inside fixing pipe 3, and motion bar 2 can be upper and lower by governor motion
Mobile is matched with fixing pipe 3, so as to realize that handrail body 1 is high relative to moving up and down for fixing pipe 3 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 the bottom of motion bar 2, fixed mount
5 positioned at the side of elevating lever 4 and affixed with fixing pipe 3, and ratchet 6 is rotationally connected with fixed mount 5, and elevating lever 4 is in close to fixed mount 5
Side is provided with some necks 41 along longitudinal arrangement.When lifting handrail body 1 is allowed to move up, the center of gravity of ratchet 6 is close to elevating lever 4
Side, the gear for realizing height by the cooperation of ratchet 6 and neck 41 are adjusted.
Specifically, with reference to 3~Fig. 7 of figure, such as known ratchet, including circular or approximately round circular portion 61 of ratchet 6
And the pointed part 62 formed by the evagination of circular portion 61, its rotating shaft 7 are arranged in the middle part of circular portion 61, pass through rotating shaft 7
Its rotation connection is realized in connection with fixed mount 5.It is appreciated that the center of gravity of ratchet 6 is close to wedge angle positioned at circular portion 61
At part 62.The center of gravity of ratchet 6 is close to the side of elevating lever 4, that is, pointed part 62 is close to elevating lever 4.In lifting handrail body 1
When being allowed to move up, elevating lever 4 moves up therewith, and ratchet 6 slightly turns under the promotion of elevating lever 4 to away from the direction of elevating lever 4
Do not influence to move past journey thereon；When stopping lifting handrail body 1, in the presence of self gravitation, its pointed part 62 is caught in ratchet 6
Within the neck 41 of corresponding height, so as to prevent elevating lever 4 from declining, handrail is the state for being maintained at corresponding height.
With reference to 4~Fig. 6 of figure, bottom evagination of the elevating lever 4 in neck side forms convex tendon 42.Ratchet 6 is provided with block 63, gear
Block 63 be located at the vertical axis of rotation of 6 circular portion of ratchet 61 to two sides on, and rounded portions are extended to by the middle part of circular portion 61
Divide 61 edge.Ratchet 6 is additionally provided with gag lever post 64, and gag lever post 64 is on the pointed part 62 of ratchet, and in both sides edge respectively
The rotation of ratchet is axially extending.Fixed mount 5 away from the side of elevating lever 4 in being provided with limiting section 51.With reference to figure 8 to Fig. 9, handrail body
1 when moving up to limiting condition (i.e. extreme higher position), then lifting handrail body 1 upwards, and convex tendon 42 abuts block 63 and simultaneously passes through promotion
The center of gravity that block 63 and then promotion ratchet 6 turn to ratchet deviates from the side of elevating lever 4, 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
Away from elevating lever 4, i.e., handrail body 1 can be pushed to reduce height without interaction with elevating lever 4 and its neck 41.
With reference to 4~Fig. 6 of figure, elevating lever 4 includes cooperatively forming connecting portion 43 and the neck portion 44 of inverted L shape, wherein connecting portion
43 are adapted to the internal diameter of fixing pipe 3, and neck portion 44 is located under connecting portion 43, and narrower width, are set so as to be formed with fixing pipe 3
Put gap.Fixed mount 5 is provided between the side of neck and the setting of fixing pipe 3 under connecting portion 43 positioned at neck portion 44
In gap.The bottom surface fovea superior of connecting portion 43 forms the curved portions 431 for making way for ratchet 6.The one end of curved portions 431 away from neck portion with
Fixed mount 5 abuts, and fovea superior degree increases gradually with close to the direction of neck portion 44.With reference to 10~Figure 11 of figure, handrail body moves down
During to limiting condition (extreme lower position), the pointed part 62 of ratchet 6 is located at curved portions 431 and abuts side with fixed mount 5, under continuing
Pressure, arcuately portion 431 turns to center of gravity and replied close to neck portion 44 side ratchet 6, now lift again handrail can carry out it is foregoing
Height regulation.
With reference to figure 1, the handrail of the present embodiment also includes a bushing 8, and the adaptation of bushing 8 is socketed within fixing pipe 3, above-mentioned tune
Section mechanism is arranged within bushing 8, and fixed mount 5 and the bottom of fixing pipe 3 are affixed by bolt, and fixed mount 5 passes through with the side of bushing 8
Pin is affixed, it is achieved thereby that bushing 8 and fixing pipe 3 are relatively fixed.From the point of view of from the appearance, outer wall non-bolt of fixing pipe 3 etc.
Connector, outward appearance is more succinct, in addition, steadiness can be also improved, isolation steam etc..
With reference to figure 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 on handrail between lid 11 and handrail lower cover 13.Motion bar 2 is fixed on the bottom of armrest support 12, and by the bottom of armrest support 12
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, tailored appearance is without interface, and lid may be provided with the comfort level that soft structures use to increase on handrail.
Above-described embodiment is only used for further illustrating a kind of height-adjustable handrail of the present utility model, but this practicality is new
