Abstract

The utility model relates to a windproof sun and rain umbrella. Elastic linking bones are additionally arranged on long bones of the original hand-open type or automatic open umbrella. Open doors of umbrella sheets with the same specifications are reduced in order to increase the upward turnover resistance of an umbrella fabric. The linking bones are connected with bead sleeves and naturally bended downwards when in use so that the bead sleeves are prevented from touching walkers when the bead sleeves extends outwards. The improvement of an umbrella crown makes the shape of the umbrella more beautiful, and the downward flowing speed of rain water is increased. The umbrella skeleton structure of the original hand-open type or automatic open type umbrella is not changed by the utility model. Umbrella factories can put into production by making a little change under the condition of no change of the original basic technology, and the cost is improved slightly.

Description

The weatherproof umbrella

A kind of weatherproof umbrella, the utility model relates to hand-held article.

Hand open type of supplying on the market or the en-toutcas of opening automatically mainly are made up of umbrella handle, umbrella bar, umbrella top, long bone, support bone and umbrella cover etc.When this umbrella used, wind loading rating was poor, and since the pearl on the long bone to be enclosed within umbrella cover protruding when strutting, thereby locate usually will touch pedestrian's dangerous phenomenon in that the crowd is dense.Shanghai system umbrella one subsidiary factory once manufactured experimently a kind of wind resistance umbrella that is commonly called as two bone umbrellas, its measure be on long bone, increase again one group slightly be shorter than long bone draw bone to be subjected to strong wind with minimizing the time umbrella cover is resupinate may.But the umbrella of this form during fabrication certainly will will change the structure chart of former umbrella frame, increase the weight of former umbrella, and cause umbrella factory cost to improve, and do not solve pearl and be enclosed within umbrella cover outwardly directed state when strutting.

The purpose of this utility model is exactly to do some improvement on the basis of original hand open type or self opening en-toutcas, so that the en-toutcas after improving improves wind loading rating, and can avoid touching in use the pedestrian, umbrella after the improvement struts also more original attractive in appearance of its umbrella shape of back, and cost improves very little.

Fig. 1 is the schematic diagram of hand open type weatherproof umbrella, among the figure 1 be umbrella handle, 2 for the pearl cover, 3 for synthetism, 4 for lower wall, 5 for support bone, 6 for the folder horse, 7 for long bone, 8 for the umbrella bar, 9 for last dish, 10 for the top spring, 11 for umbrella top, 12 for umbrella cover, 13 be flat spring.

Fig. 2 is the schematic diagram of synthetism 3.

Fig. 3 is the schematic diagram of umbrella top portion, and 14 are the cap of abandoning among the figure.

Fig. 4 is a schematic diagram of opening the wind resistance umbrella automatically, and 15 is the switch plate spring among the figure, and 16 is that mid-game, 17 is for drawing bone, 18 to be deployment spring.

Now by reference to the accompanying drawings the utility model is described.

Measure of the present utility model is to connect the synthetism 3 more much better than the material of long bone 7 of one section elasticity on the long bone 7 of former hand open type or self opening en-toutcas, the shape of synthetism 3 as shown in Figure 3, it is that 0.3～0.8 millimeter medium carbon steel or the compacting of spring steel band material forms that thickness are adopted in synthetism 3.The lower end of synthetism 3 is pressed into cylindrical, can be inserted in the pearl cover 2, and the fish antiform or watt shape of slightly bending in the middle of the stage casing is pressed into, the upper end is rolled into the end that can wrap up long bone 7 securely.Abandon be seamed into umbrella cover 12 the umbrella sheet its open the door and will cut out more smallerly than same specification, specification for 50 centimeter 8 fulcra, opening the door before improving is 340 millimeter, of the present utility model opening the door is 310～320 millimeters, for 55 centimeter 8 fulcra, opening the door before improving is 380 millimeter, of the present utility model opening the door is cut into 350～360 millimeters, after improving like this, when strutting umbrella cover 12, synthetism 3 just has been subjected to the pressure of umbrella cover 12, and is bent downwardly naturally, thereby has just increased umbrella cover 12 resupinate drag when lifted by strong wind to blow.And, so just can not touch the pedestrian when locating to use in that the crowd is dense because to be enclosed within the head of the pearl cover 2 in the synthetism 3 be downward.The length of synthetism 3 is different with elastic properties of materials among Fig. 2, in general, adopt the bigger material of elasticity, synthetism 3 can be longer, otherwise then short, under the situation that adopts medium carbon steel, length can be 85～100 millimeters, and the specification difference of umbrella, and synthetism 3 length are also different, under 50 centimeters situation, length is 85～90 millimeters.In addition, the utility model has also been done some improvement in the umbrella top portion, promptly on last dish 9, place a top spring 10, and be enclosed within on the umbrella bar 8, being equipped with a threaded cap 14 of abandoning in upper end on the top spring 10 again, center closing in place of umbrella cover 12 is enclosed within on the external screw thread of the cap 14 of abandoning, screw in umbrella top 11 then, but umbrella cover 12 is fixed on the umbrella bar 8 with regard to floating ground like this, and the horizontal aperture on the angle of umbrella cover 12 every pieces and the pearl cover 2 is used the linear slit jail, then pearl is overlapped 2 by shown in Figure 2 being enclosed within the synthetism 3.After doing to improve like this, when umbrella cover 12 struts, under the effect of top spring 10, the core of umbrella cover 12 just becomes a tall and straight peak, umbrella shape so not only attractive in appearance, and can reduce the pressure of wind, and the speed of the downward trickling of increasing rainwater, thereby improved water-resistant performance, the umbrella after the improvement is because the fixed form of umbrella cover 12, thereby after umbrella cover 12 usefulness are dirty, as long as umbrella top 11 is screwed out, pearl cover 2 is deviate from, and just can easily unload sub-umbrella 12 and wash and eliminate.

The utility model is not owing to change the structure of former hand-opened type or self opening umbrella rib, thereby umbrella factory can go into operation as long as do very little change under the prerequisite that does not change the basic technology route, so that cost improves is very little, the consumer also is easy to acceptance.
