embodiment:
Fig. 1 illustrates the mode as the pump in the present invention and disabled wheelchair Y orientation assemble of inflating that bar 4 forms by vertical-type inflator pump 2 and vertical-type, its key is: pump and long-armed bar 1 can adopt the aluminium sheet of the plastic plate of thick 0.5 centimetre or 0.3 centimetre to determine its geomery with reference to the reference position of Fig. 1 signal by transition substrate S() to become the bridging mode of " T " font with disabled wheelchair Y shape, pump and long-armed bar 1 is allowed to be located by transition substrate S and disabled wheelchair Y, and under making the lower front locking point d of vertical-type inflator pump 2 bottom and the axle ends of long-armed bar 1 bottom after all have employed can the bridging mode of clockwise or counterclockwise angle of swing displacement (such as: its angle of swing can be considered at 45 degree) on the vertical plane in locking point b two positions, and vertical-type inflation bar 4 top and above-mentioned long-armed bar 1 stage casing have employed and can either rotate angle displacement, the dual bridging mode of roll displacement in orbit can be there is again on long-armed bar 1, the position at this dual bridging mode place, namely the movable linking node of above-mentioned inclination " T " font is defined.
Obviously, the size of transition substrate S and body and finally on disabled wheelchair Y, arrange position, be subject to the one-sided configuration (comprising the layout of wheel wherein and chair) of disabled wheelchair Y and the dual restriction of inflator structure:
For disabled wheelchair Y, be positioned at at least three best fastening point of transition substrate S: two endpoint locations of bench g side length direction and the side endpoint location of wheel h axle, namely the upper rear locking point a of bench g avris and the locking point c that goes forward is positioned at, and rear locking point b under axle ends.
For pump, be arranged on the long-armed bar 1 on pump length and in the operational range of this long-armed bar 1 of manual processes upper and lower displacement, should not be subject to the obstruction of transition substrate S itself or its outer rim and the obstruction of disabled wheelchair Y, in the middle of the process of the long-armed bar 1 of the upper and lower displacement that namely handicapped people is manual, the hand holding long-armed bar 1 handle can not be subject to stop or the restriction at other positions in the present invention.
Fig. 2 illustrates the detail drawing (illustrating the connected structure principle of associated components in its medium dip " T " font movable linking node) that pump is arranged on W position crucial on disabled wheelchair: described long-armed bar 1(can be made up of interior crimping metal section (such as: channel-section steel or groove aluminium), such as: overall length 50cm, its section top width 4cm) top be decided to be manual handle position place place and (can the handle be made up of plastics or timber be set on top, or the handle similar in appearance to handle function being wrapped in above-mentioned end with sponge and being formed, to guarantee to feel comfortably cool when driving pump to hold), manually during this handle upper and lower displacement, namely drive the external extracting air of pump and internally compress and the process be externally vented:
When handicapped people manually this handle move, long-armed bar 1 is rotated counterclockwise, and roller 3 is by the effect of the lower railway inwall power obliquely of long-armed bar 1, and roller 3 slightly moves downward along the lower railway inwall of long-armed bar 1, allow piston produce by vertical-type inflation bar 4 upwards run, external extracting air.
When manually this handle moves down handicapped people, long-armed bar 1 turns clockwise, roller 3 is by the oblique effect of exerting oneself of the inwall that gets on the right track of long-armed bar 1, roller 3 slightly moves upward along the inwall that gets on the right track of long-armed bar 1, allow piston produce by vertical-type inflation bar 4 run downwards, to compressed air, and externally discharge air by the conventional outlet pipe arranged.
Fig. 3 is the Z-direction view in Fig. 2, the connected structure of associated components the movable linking node of above-mentioned inclination " T " font is illustrated from another flank angle, obviously, the vertical-type inflation bar 4 in the present invention is implemented to bleed to be achieved in that with the telescopic process be vented by driven plunger
When manual long-armed bar 1 upper and lower displacement, the displacement that the inwall up and down of long-armed bar 1 (upper lower railway) compressing one pair roller 3 that all can exert a force respectively carries out being dominated by rolling character, roller 3 is oppressed axis 5 and is carried out linear displacement, axis 5 is oppressed hole again and is driven vertical-type inflation bar 4 piston conventional in vertical-type inflator pump 2 to carry out displacement up and down, thus reaches the object of bleeding with being vented allowing pump realize routine.
In order to realize above-mentioned bleeding and the object be vented, structurally intend adopting following design proposal:
Both sides through the axis 5 of vertical-type inflation bar 4 top hole are provided with a pair roller 3, gap is there is between inwall (upper lower railway) up and down in this roller 3 and long-armed bar 1, the size in this gap should just in time make roller 3 descend in inwall (upper lower railway) thereon one-sided can compression rolling, but the phenomenon that can not produce obvious displacement between this upper and lower inwall (upper lower railway) and teetertotter.
So far, be not difficult to find out:
One, length as the manual long-armed bar 1 with arm of force character should lengthen as best one can, long-armed bar 1 length that is longer or pump is shorter, it is just laborsaving when then handicapped people inflates, according to this principle, pump in the present invention can according to the health degree of handicapped people's upper body, value is 30 centimetres, 25 centimetres, 20 centimetres, even less, after the length data determining above-mentioned key, corresponding other sizes (comprising the size of all parts or element) and material require to determine with reference to the related data of the vertical-type of different size in prior art " pump " completely, this is easily and lifts just soluble matters, here just do not detail one by one.
Two, hand-power required when the present invention utilizes the pump of prior art to inflate can be little compared to the hand-power needed for CN103976828A technology, now, its exhaust efficiency obviously can be lower, but can offset above-mentioned inefficient key element by the repeatedly long-armed bar of manual upper and lower displacement 1 completely.---key is that the present invention can be suitable for the Man's Demands be sitting on disabled wheelchair Y of various health.
Three, because main purpose of the present invention allows the handicapped people sitting disabled wheelchair Y can without the need to just oneself can to complete the overall process of manually inflation when foreign aid to the wheel h inner tube of a tyre of disabled wheelchair Y; This problem easily solves, before handicapped people manually inflates, while only with hand rotating-wheel h allows disabled wheelchair Y be shifted, the conventional valve that the wheel h inner tube of a tyre is arranged can be forwarded to the extreme higher position when top of wheel h (forward to manually-operable most convenient) of wheel h, the relief opening that arrange outlet pipe conventional on vertical-type inflator pump 2 just can dock with wheel h inner tube air valve by handicapped people as persons without a disability.
Finally, can see, in order to realize allowing handicapped people can the singlehanded manual step driving long-armed bar 1 inflate this key effortlessly, always can accomplish: allow pump and long-armed bar 1 locate by transition substrate S and disabled wheelchair Y the bridging mode that forms " T " font and the handicapped people be sitting on disabled wheelchair Y can be facilitated and uses pump to carry out manual overall process of inflating to the wheel h inner tube of a tyre on disabled wheelchair Y effortlessly; Especially for most handicapped peoples that disabled wheelchair Y can be driven to advance by the hand-power of self, all processes of manually inflation can be completed especially by the wheel h inner tube of a tyre of pump of the present invention to oneself.
