Specific embodiment:
Idler wheel (7) are mounted on two side faces above along balustrade (5) in the shell (8) of walk helper (3), make walk helper
(3) it can be rolled on balustrade (5), and certain lateral force can be born;Brake shoes (11) presses closer under balustrade (5)
Plane, brake shoes (11) head on it there are also brake spring (13) below, and the top power for controlling brake spring (13) can be smooth fine and smooth
Ground controls the brake force of brake shoes (11), so that the speed of service of walk helper (3), brake shoes can be controlled smoothly fine and smoothly
(11) with maximum braking force Shi Weiqi normality, so when not used, walk helper (3) can be parked on balustrade (5).Two are helped by stick
It (9) is L-shaped iron pipe, helping upstairs is arranged as vertical arm in Top Crossbeam under by stick, and helping downstairs is arranged as vertical arm by stick
In lower cross arm upper, this is because it is transverse arm that people, which helps lean on, upstairs when people it is lower with respect to the position of walk helper, so transverse arm exists
Under, and downstairs when people it is higher with respect to the position of walk helper, so transverse arm is upper.They are installed by hinge (10), can
To collapse and be unfolded.It can also be with helping backup plate (22) to replace helping by stick (9).It is pressed against when people's stair activity with elbow and helps backup plate (22)
The upper walk help for obtaining walk helper.Installation for power mechanism (4), the present invention devise two kinds of mounting means: the first installation
Mode: power mechanism (4) is mounted on the railing (6) below each folding balustrade (5) upper end, then in balustrade (5)
Upper installation fixed pulley (1), pull strap (2) connect around fixed pulley (1) with walk helper shell.
Second of mounting means:
Power mechanism (4) and walk helper (3) are linked into an integrated entity, walk helper (3) lower half is arranged in, gets out of the way brake shoes
(11) place, fixed pulley (1) are mounted on walk helper (3) upper end and are fixed on stair after pull strap (2) bypasses fixed pulley (1) and help
The upper end of hand (5).To keep the operation of walk helper (3) safer, the present invention devises two kinds and controls walk helper (3) with mechanical structure
The mode of running force:
The mode of the first control walk helper (3) running force: it helps and is directly installed on walk helper by hinge (10) by stick (9)
On shell (8), brake spring (13) is the floating end of oscillating deck (14) below, is headed below it by cam (15), oscillating deck
(14) hingedly by small axis (17) and shell (8), cam (15) can be manipulated the other end by control stick (12), control stick (12)
On have torsional spring (16), the effect of torsional spring (16) is that the normality of cam (15) is made to be maintained at the position for holding out against brake spring (13), is made
Walk helper (3) is keeping halted state when not used;The switch of power mechanism (4) is mounted on control stick (12).Upstairs or downstairs
When, long-armed expansion by stick (9) is helped, people helps lean against and help on stick (9) and shell (8), and stirring control stick (12) makes cam
(15) pressure to brake spring (13) is reduced, that is, reduces the brake force of brake shoes (11), walk help (3) is in engine
To helping the human body leaned on to provide certain uplink power under the action of the pulling force that structure (4) is provided by pull strap (2), people can be light
By means of power stair activity, from the foregoing, it can be seen that, the size of speed uplink and uplink power that walk helper (3) provides can pass through control stick
(12) it manipulates, and brake spring (13) can make manipulation become to be easy to the manipulation amplitude of broadening control stick (12).
The mode of second of control walk helper (3) running force: shell (8) is provided with pressure-bearing spring (19), and elastic force is greater than
Brake spring (13), side are equipped with movable plate (20), help and be mounted on movable plate (20) by stick (9) by hinge, movable plate
(20) upper end has pressing plate (26) to put in shell (8) from plate hole (18) and is fitted on pressure-bearing spring (19), under movable plate (20)
End has supporting plate (21), and supporting plate (21) presses against brake spring (13) in the following, walk helper (3) is made to keep halted state, power mechanism
(4) switch be mounted on people on movable plate (20) help by when most nearby from finger.It is long-armed by stick (9) helping when upstairs or downstairs
Expansion is vertical with shell (8), and people can help lean against and help by stick (9) and help on backup plate (20), easily borrows power stair activity, walk help
The size for the uplink power that device provides depends on people
The pressure for leaning against and helping on stick (9) and movable plate (20) is helped, this pressure is big, and pressure-bearing spring (19) is pressed low, and
With regard to low, supporting plate (21) is applied to brake shoes by pressing brake spring (13) for the position of the supporting plate (21) of movable plate (20) one
(11) brake force is also just small, and the uplink power that walk helper (3) provides is with regard to big, conversely, the uplink power that walk helper (3) provides is with regard to small.
