Handle part 16f would not be bumped against when basket 23.In addition, H4 is the height of shopping basket 23, θ2It is shopping basket vertical line and shopping
The angle of basket side, the angle are identical as the angle of shopping basket platform 20.In order to not sent out with handle part 16f when picking up shopping basket 23
The bottom surface back of raw conflict, shopping basket platform 20 needs the front positioned at the front end of handle part 16f.
From the above description, it can be seen that shopping basket platform 20 is made of mounting frame 21 and side frame 22, mounting frame 21 is than side frame 22
Slightly, mounting frame is firmly fixed on strut support 15, so heavier load can be born, it is firmer than previous technology.Thus may be used
To solve above-mentioned improvement point (c).
The assembling of trolley is illustrated referring to Fig. 1~Fig. 5.
First, supporting rack 13,14 and strut support 15 are assembled.For the assembling, in the present embodiment, supporting rack 13
It is made of a frame with strut support 15, so supporting rack 14 is fixed on strut support 15.
Above-mentioned fixation is 15 that strut support 15 is fixed on by welding1、152At two.
Front-wheel 11 and trailing wheel 12 are fixed in a pair of supporting 13,14.On the other hand, by shopping basket platform 20 and forearm branch
Support platform 19 is fixed on handle holder 16.The handle holder 16 is completed into assembling on strut support.
In addition, shopping basket platform 20 may be also secured at except being fixed on handle holder 16 on strut support 15.
As described above, the height of trolley 10 can adjust use within the scope of 94cm~116cm, can be according to using
The height of the height regulation handle frame 16 of person uses.
Trolley 10 is tested under the following conditions, has obtained result.
(f) condition
Before improvement (previous trolley)
When placing shopping basket on shopping basket platform, center of gravity is located at the position in the front that direction of travel is close to than front wheel axle
The trolley of structure.
The article that 15kg is loaded on shopping basket platform, applies the power of 40N from forearm supporting table side, and observation front-wheel bumps against
State when 5mm high steps.
After improvement (trolley of the application)
The article that 18kg is loaded on shopping basket platform, applies the power of 50N from forearm supporting table side, and observation front-wheel bumps against
State when 5mm high steps.
(g) result
(h) it investigates
Trolley load-bearing 15kg before improvement, when applying 40N power, trailing wheel can lift.But the trolley energy load-bearing after improving
18kg, when applying 50N power can trailing wheel do not pass through step with not lifting.
By above-mentioned investigation it has been confirmed that the trolley of the application can press down compared with the previous trolley before improvement
It makes and then prevents trolley from swinging to front.
Referring to Fig. 1 to angle, θ1~θ5Relationship illustrate.
The frame part 13b of support arm 13 distances as defined in the ground are parallel to the ground, the shopping basket peace of handle holder 16
Dress portion 16b is parallel with frame section 13b, under this condition, angle, θ1~θ4Relationship it is as follows.
θ1=θ4·········(1)
θ1=θ2+θ3·······(2)
θ can be obtained from (2)2It is as follows：
θ2=θ1--θ3·······(3)
θ is set first1.Front-wheel 11 is fixed on to the front that conduct direction is leaned on than imaginary drop wire P2, by 13 He of supporting rack
The engaging portion of strut support 15 is arranged in the position for leaning on front wheel side than imaginary drop wire P1, and forearm supporting table 19 is arranged in trailing wheel 12
Surface even be biased to front-wheel position.
In this way, being remained in lower angle in suitable range, optimum value is 105 °.
θ1=100 °~110 ° (4)
If angle, θ1More than 110 °, handle holder 16 can be thus lifted to extreme higher position, and forearm supporting table 19 can be in trailing wheel
12 rear, trolley even people have the danger for swinging to rear.On the other hand, if angle is less than 100 °, center of gravity can be to
Direction of travel moves, and trolley has the danger for swinging to front.
According to the θ of above-mentioned (4)1Range and (2) formula be arranged θ2.In addition, θ3=90 ° are controlled condition.
θ2=θ1-θ3- 90 °=10 °~20 ° of=(100 °~110 °)
Therefore, θ2OK range be 10 °~20 °.
If the angle, θ2Less than 10 °, center of gravity can be difficult to move to direction of travel, when angle is more than 20 °, be positioned in
Setting the shopping basket on face can collide with handle part, it is difficult to take up.
In addition, θ5With θ2Corresponding, angle initialization is 35 °~45 °, to ensure that the shopping basket being placed in mounting surface will not be with
Position is held to collide.
Above-mentioned improvement point (a) and (b) are solved as a result, though do not apply pressure in the forearm supporting table of trolley, and
Increase the weight of put items on shopping basket platform, also trolley will not be to traveling side when front-wheel bumps against rugged step etc.
To front topple over, can feel at ease, safely carry out ambulation training and shopping etc..I.e. a pair of posts frame is arranged in a pair of supporting
On from than intermediate position by direction of travel front direction rear wheel-side tilt (angle, θ1) and erect setting, it is possible to higher
Position on forearm supporting table is arranged to front direction of travel in the surface including trailing wheel.Even if forearm or ancon as a result,
It is placed on the gravity for applying whole body in forearm supporting table, front-wheel, which will not lift, causes trolley and people to swing to rear.
In addition, if by the angle, θ of each strut support1Shopping basket platform angle, θ can be selected by being set as defined angle2Choosing
It is set to best angle, when placing article on shopping basket platform, the center of gravity of trolley can shift to rear, be conducive to inhibit even to prevent
Trolley is toppled over to direction of travel front.Further, because front-wheel be installed in it is more sagging than by the central part of shopping basket platform
Imaginary drop wire in front of the direction of travel, so even if not applying weight to forearm supporting table, be also possible to prevent trolley
It dumps forward because front-wheel bumps against step.
In addition, above-mentioned improvement point (e), i.e. trolley 10 carry out needing brake gear when ambulation training, so to install brake
Vehicle device.Brake gear is mounted on the positions such as supporting rack and handle holder, is made of brake block, operating handle and steel wire rope, brakes
The wheel contacts of at least one party in piece and front wheels and rear wheels and prevent its rotation, operating handle from being arranged in handle holder with frictional force
