Description

Unload and resist high wind screening rain, parasols strenuously

The present invention relates to a kind of new daily screening rain, parasols, particularly about hiding rain, the innovation of parasols on the method for laying down wind-force opposing high wind.

Existed umbrella and large and small type parasols, when blowing hard, wind is scurried row and is blown from bottom to top to the bottom of umbrella, or the umbrella cover pocket is when wind, hold moment of umbrella is heightened, or make the long bone of umbrella not resist powerful wind-force, and very easily upwards dig its outer.In order to overcome this shortcoming, more existing umbrellas, as ZL94195161: non flip umbrella and ZL96222778: as described in a kind of parasols skeleton with wind resistance function, all just concentrate on the skeleton structure of umbrella is improved, it strengthens the windproof method is by strengthening the rigidity of umbrella frame frame, strengthen the ability that umbrella is direct in use and wind-force contends with, do not have to adopt the method for laying down wind-force effectively to reach the windproof purpose, in fact its windproof effect is not fine.

At the problems referred to above, the purpose of this invention is to provide a kind of simple in structure, implement easy method, make of the present invention unloading resist that high wind hides rain, parasols can be laid down part wind-force and reach the purpose that opposing high wind blows strenuously.

To achieve these goals, of the present invention unloading resists that high wind hides rain, parasols takes following method for designing to achieve the goal strenuously.Press Fig. 1, Fig. 2, described: it forms the umbrella frame frame by members such as handle of umbrella 9, column 1, umbrella long bone 6, support bone 5, slipping ring 4, pin joint P, forms by umbrella cloth 2, wind outlet 8, anti-blowback filter 7 and leakproof rain cover 3 etc. and to unload the wind umbrella cover, unload the laying of wind umbrella cover and be connected on the umbrella frame frame.When opening umbrella and use, umbrella all is that the umbrella frame frame that member such as the column 1, umbrella long bone 6, support bone 5, slipping ring 4, pin joint P by umbrella is formed supports umbrella cloth 2 usually, reaches the purpose that hides rain, sunshade.When blowing, wind can blow from different directions, and existing umbrella is that its wind loading rating is to have obtained partly strengthening by the rigidity of strengthening umbrella long bone 6 and support bone 5 etc. on the umbrella frame frame stronger wind-force that contends with, but effect is still undesirable.Because the umbrella frame frame supports and is being connected umbrella cloth 2, form the arcwall face of interior bow downwards.This outer umbrella cover upwards stressed, described umbrella cloth 2 has the support of umbrella frame frame tension force, form arc extrados, stronger for the wind resistivity that head-on blows, wind-force is discharged than the outer arcuate face that is easier to along umbrella, therefore, blown by wind-force and the chance that occurs making umbrella inwardly to fold is few, also little to the destructiveness that umbrella caused.And umbrella cover stressed in downward this is the inboard of the described one by one umbrella cloth 2 of concave profile of umbrella, and be then relatively poor for the wind-force resistivity of blowing from bottom to top.When scurrying the concave profile of capable wind from umbrella when blowing from bottom to top, because the inboard of umbrella cloth 2 is concave profiles of umbrella, positive pocket wind-force, and wind-force is difficult to be laid down.When the wind-force that blows from bottom to top when this strand is enhanced to a certain degree, can produce very big pushing force to the umbrella intrados, this strand wind-force changes the upwards tractive force to umbrella long bone 6 into to the pushing force of umbrella cloth 2 inboards on practical function, make the 6 stressed outside upsets of umbrella long bone.Thisly the pushing force of umbrella cloth 2 inboards is converted into outside tilting force to the umbrella long bone, is directly proportional with the size of scurrying the wind-force that row blows from bottom to top to the umbrella inboard by wind-force.When this strand wind-force arrived to a certain degree greatly, two kinds of results can appear: the one, and umbrella long bone 6 is outwards turned down, or make umbrella disengaging hold blow away (when especially children use umbrella, the hold deficiency usually occurs, umbrella is blown away by wind) with the wind.We know in daily when using that with respect to umbrella, wind does not blow from there being fixing direction at any time, and the user of umbrella often has hard to guard against sensation, and the scene of these two kinds of embarrassments more than occurring in wind and rain all can be brought great inconvenience to the user of umbrella.

When running into the high wind umbrella and go for a drive again for reduce as far as possible, its umbrella long bone 6 stressed outwards upsets easily, strengthen the wind loading rating of umbrella, reduce the hold of umbrella, the present invention realizes by the following method: we have directly opened a plurality of larger area wind outlets 8 that have on the umbrella cloth 2 between Fig. 1, the described two umbrella long bones.When the intrados pocket of umbrella wind-force, and not exclusively by the rigidity of the umbrella frame frame active force that wind-force produces umbrella that contends with, but allow part wind-force waltz through wind outlet 8 with suitable deal, it is drained away.When the area of wind outlet is moderately strengthened, because constantly being arranged, wind-force lays down, be the pushing force of described umbrella cloth 2 inboards to described umbrella intrados, can be become integral multiple ground to reduce.This wind-force can be weakened by the drainage of wind outlet 8 widely to the pushing force of umbrella intrados, and the required hold of the power of turning up of umbrella long bone and umbrella is also weakened simultaneously, makes described screening rain, parasols reach the ability of anti-high wind.Wind outlet 8 is opened in the centre by umbrella long bone 6 simultaneously, near the position of umbrella long bone 6 with the pin joint P of support bone 5 handing-over, is the weakest place of umbrella frame frame rigidity here.Because the distance that stretches at the outer of umbrella part umbrella long bone 6 is far away, this part shared area is bigger, bear also maximum of wind action power, but the umbrella cloth of this part supports by the independent connection of umbrella long bone 6 fully.And umbrella long bone 6 is by one section of the inner, umbrella top, there is support bone 5 coupled as turning joint; umbrella constitutes leg-of-mutton stable shaped when being strutted; can produce the support force and the tractive force of mutual support between umbrella long bone 6, support bone 5, column 1 and slipping ring 4, constitutes a rigidity body by pin joint P; The outer part of umbrella long bone 6 is then different, becomes a lever arm of force that is suspending in midair naturally fully, only relies on the connection location of umbrella cloth 2.This also is the existing this intrinsic tactic pattern that produces produced various screening rain, parasols, determined whole the weakest place of umbrella wind-engaging power effect, be exactly at the pin joint P front end of support bone 5 and umbrella long bone 6 a little on the position away from umbrella top direction, just near the middle part of umbrella long bone 6.This is most of umbrellas places of easy outside turnover when being subjected to wind-force and blowing.Because in the suffered wind action power maximum of the umbrella cloth 2 of umbrella outer, these active forces are all concentrated and are delivered on several umbrella long bones 6 few in number, umbrella long bone 6 can only by it self and support bone 5 pass to column 1 to power again.Be delivered to the joint of umbrella long bone 6 and support bone 5 when this power---pin joint P, because what column 1 was suffered is the hold of drawing vertically downward, and umbrella cover bore is the pushing force that wind-force blows from bottom to top, opposite fully with the hold on the column 1, the direction of transfer of power changes at pin joint P, one wind-force that upwards blows and one hold that pulls down are at the front end of umbrella long bone 6 with the pin joint P of support bone 5, the middle part that is umbrella long bone 6 contends with, contending with of these two strands of rightabout active forces, consequently produce a leverage power, make bending of umbrella long bone or upwards upset in the middle part of umbrella long bone 6.In order to address this problem, we adopt the method for cutting off a plurality of wind outlets 8 on this position that the wind-force of part is discharged.The area of wind outlet 8 size and number how much be to set according to the needs of the different functions of use of various screening rain, parasols, the area of wind outlet is big more and the more wind-force that unload of number wind outlet just big more more, and the aligning method of wind outlet 8 on umbrella cloth 2 can be arranged in the form of single row or multiple rows.Owing to can form certain pushing force when going for a drive in umbrella cloth 2 inboards, this pushing force can force the wind pick up speed by wind outlet 8, lay down wind-force, reduce the wind-force effect of umbrella cloth 2 inboards when going for a drive widely, also reduce umbrella long bone 6 and bear and outwards stick up the lever force of turning over.In accompanying drawing 1, we cut off out wind outlet 8 on the umbrella cloth between two umbrella long bones 62, and the spaced apart spacing air port of not starting discharging between umbrella long bone and the umbrella long bone.This can reach our desired purpose of unloading wind in many cases, because the wind-force that wind outlet 8 is laid down all has the effect that slows down power to two adjacent umbrella long bones.How much can setting of the area of wind outlet 8 size and number according to the needs of the different purposes of umbrella.

Adopt described a plurality of described wind outlets 8 of on umbrella cloth 2, opening, can lay down the method for the wind-force of part.Can reach the purpose of the wind loading rating that strengthens umbrella.In order to solve the problem of described wind outlet 8 open ports roof leaking, light leak, we add the above leakproof rain cover 3 and solve this problem above each wind outlet 8.The area of leakproof rain cover 3 is bigger than the area of wind outlet 8, and the umbrella cloth 2 of the base of leakproof rain cover 3 and wind outlet 2 left and right sides and top edges is sewed or bonded together.Leakproof rain cover 3 is divided into the nature hang and is backed down and partly back down state entirely by wind-force, and the calm masterpiece time spent, leakproof rain cover 3 openings let droop naturally and are against on the umbrella cloth 2; When not being very strong wind when blow from bottom to top the inboard of umbrella, leakproof rain cover 3 can partly be backed down or be in half-open position by wind-force, form an air flue that unloads wind-force, allows wind waltz through; When wind-force increases to a certain degree, it is maximum that the aperture of leakproof rain cover 3 reaches, reach the state that backs down entirely, at this moment arrange the ability of unloading wind-force and also reach maximum, one of external surface shape of described leakproof rain cover 3 as shown in Figure 1, be arc planar (we are according to the demand of the aesthetic conceptions of different people, the external surface shape of described leakproof rain cover 3, are designed to plane, triangle, conical shell shape etc.).Though, when row lay down distinguished and admirable during through leakproof rain cover 3, have some frictional resistances, for the umbrella, wind is to the pushing active force of umbrella cloth 2 for whole, opened after the wind outlet before more much smaller than the air port of not starting discharging.The effect of leakproof rain cover 3, be that wind is discharged through wind outlet 8 on the one hand, can wind successfully be laid down according to the flow direction that leakproof rain cover 3 set originally, effect on the other hand is to block at the rainwater that top side vertically falls and each laterally blows of umbrella and block the sunlight of penetrating above the umbrella, and keeps the original screening rain of various umbrellas, sunshade function.Because its area is bigger than the area of wind outlet 8 during 3 designs of leakproof rain cover, all sew with the base of leakproof rain cover 3 and bond together in the left and right side at wind outlet 8 edges and top, though Open Side Down for leakproof rain cover 3, above wind outlet 8, occupy certain shielded area, even under full-gear, it is maximum that the horizontal aperture of described leakproof rain cover 3 reaches.The wind-force intensity that draws off through wind outlet 8 and leakproof rain cover 3 rows from the umbrella inboard this moment, because the umbrella inboard has certain pushing force effect when going for a drive, the inevitable wind-force intensity that laterally blows greater than synchronization of the intensity of its wind-force.Raindrop is to be difficult to enter wind outlet 8 by the lateral openings of leakproof rain cover 3, leaks the umbrella inboard.When the wind-force intensity that laterally blows during greater than the wind-force intensity of discharging from wind outlet 8 and leakproof rain cover 3 opening parts, the opening part of leakproof rain cover 3 can only be in and partly back down or closed hang, and raindrop is more difficult to enter the umbrella inboard by leakproof rain cover 3.On described wind outlet 8, also made anti-blowback filter 7.The anti-filter 7 that blows of leakproof rain cover 3 and counnter attack can be fixed on the wind outlet 8 with diverse ways such as sewing or stickups simultaneously.The effect of anti-blowback filter 7 is: when wind during to the lateral surface of umbrella, can hold in the palm leakproof rain cover 8 in the inboard of umbrella.Because the grid density of anti-blowback filter 7 is moderate, even very strong wind can not blown over filter with leakproof rain cover 3 from the outside of umbrella yet, wind and rain can be intercepted the outside at umbrella effectively, can not pass through wind outlet 8 from the outside of umbrella; And scurry the inboard that blows to umbrella when blowing from bottom to top when wind, the wind energy successfully mesh the anti-blowback filter 7 from wind outlet 8 is passed, and the outside that leakproof rain cover 3 rows of backing down are discharged to umbrella, can not produce very big resistance.Anti-blowback filter 7 on Fig. 1, Fig. 2 be directly in described umbrella cloth 2 upper punches, cut a plurality of mesh, made the edge in hole again, directly on described umbrella cloth 2, be made into described wind outlet 8 and described anti-blowback filter 7.

The size and the geometry of described leakproof rain cover 3, anti-blowback filter 7 can be made into multiple pattern, and shown in accompanying drawing 1, the accompanying drawing 2 is wherein a kind of.In the actual production design, can be according on the size of unloading wind-force, the overall appearance aesthetic, complexity on children curiosity reason and the processes even, screening rain, sunshade and drip-preventing function in conjunction with umbrella need, and are designed to practical again the unloading of multiple existing aesthetic appearance and resist high wind screening rain, parasols strenuously.
