Description

Sunshade with ventilation, protection effect

The utility model relates to the improvement at parachute kit, refers to a kind of sunshade with ventilation, protection effect especially.

Umbrella, except the umbrella that hides the rain purposes, also comprising simple is the sunshade of purpose with the sunshade.Early stage sunshade design all has one group of deployable umbrella stand that folds, but the umbrella cloth of installing one shielded from sunlight on the umbrella stand.Umbrella cloth can form an obstruct face under umbrella stand launches to support, to reach the effect of covering sunburst.

Because sunshade is in order to avoiding the purpose of the sunshine shining directly person, so the umbrella cloth of early stage sunshade, the light tight cloth body that mostly is single-layer type is made.Just because of umbrella cloth for reaching lighttight purpose, its umbrella cloth is organized comparatively fine and closely woven, gas permeability is also relatively poor; Also therefore, when the hand-held sunshade of people is walked in the sun, because of the air in the umbrella can't circulate effectively, the high temperature that gathered of sunshine shining directly umbrella cloth in addition, so in umbrella formation one stuffy sultry state, thereby easily cause user's sense of discomfort.In addition, because its umbrella cloth is not had a gas permeability, so when meeting with high wind and blow, its umbrella cover easily because of the wind-force effect reverse upset takes place.

Therefore, for asking the ventilating permeability effect that improves sunshade, the sunshade of several tool multi-layer umbrella cloth structures is arranged at present.One as shown in Figure 5, the umbrella cloth 3 of this sunshade comprises a main umbrella skeleton 41 that cooperates umbrella stand 40, main chute cloth 30, this main chute cloth 30 also forms one respectively in two 41 of adjacent main umbrella skeletons and lacks empty portion 301.Cover one on the main chute cloth 30 again and can cover the secondary umbrella cloth 31 that lacks empty portion 301 in the outside again.When sunshade launch to use, air can flow into via the outer portion 311 of secondary umbrella cloth 31 gap with 30 of main chute cloth, lacks empty portions 301 through main chute cloth 30 again and flows into space in the umbrellas, to reach the purpose of promotion umbrella inner air flow.

Another ventilation sunshade, as shown in Figure 6, the umbrella cloth 5 of this sunshade also is all the combined type umbrella cloth that main chute cloth 50 and secondary umbrella cloth 51 are constituted, wherein main chute cloth 50 is the whole umbrella cover of the main umbrella skeleton 61 that cooperates umbrella stand 60 after launching, its position, stage casing is provided with the bigger gauze 501 of a hole order, and is covered in its outside by the secondary umbrella cloth 51 less than main chute cloth 50.Umbrella cloth 5 designs by above-mentioned multi-layer, when launching to use, air-flow can flow into via the gap of 50 of secondary umbrella cloth 51 outer ring edges 511 and main chute cloth, flows into the interior space of umbrella by gauze 501 districts again, and reaches the purpose of promotion umbrella inner air convection.

But above-mentioned two kinds of ventilation sunshades with multi-layer umbrella cloth structure though can reach the purpose that promotes the umbrella inner air convection, still have following some shortcomings in its structure:

1. the air intake gap is too small, the cross-ventilation poor effect: the major and minor umbrella cloth of sunshade is because of being that folded establishing is fixed on the main umbrella skeleton, when umbrella stand launches, it is tight that umbrella cloth props up lower umbrella cloth at the main umbrella skeleton that launches, so make the overlapping part of major and minor umbrella cloth almost together smooth, so that its air intake gap becomes very narrow, the umbrella cloth of quality softness strains under the effect in no external force in addition, major and minor umbrella cloth easier because of the wind-force effect together smooth, cause the convection current air can't be in large quantities to enter space in the umbrella via the two gap, so that its circulation poor effect of ventilating.

2. the required material of umbrella cloth is many: the design of multi-layer umbrella cloth in the sunshade, its main chute cloth and secondary umbrella cloth all adopt large-area material, and overlapping position is too much between major and minor umbrella, causes the unnecessary waste of umbrella cloth material, and the higher problem of material cost is arranged.

3. manufacture too loaded down with trivial details: in the multi-layer umbrella cloth structure of sunshade, offer the scarce empty portion of number on the main chute cloth or connect and establish gross porosity purpose gauze, to promote ventilation effect; But because originally main chute cloth, secondary umbrella cloth are to be formed by number cloth body sewings triangular in shape, the present more in addition the cloth body hollow out, connect and establish gauze, make that the processing and manufacturing of umbrella cloth is too loaded down with trivial details, the cost of time is also more, so the higher problem of manufacturing cost is arranged.

4. protection effect is not good: as previously mentioned, almost together smooth because of the major and minor umbrella cloth overlapping part of sunshade, and air-flow effectively imports and exports too smallly, and makes the air-flow can't the moment circulation of the gap between major and minor umbrella cloth in large quantities; Equally, when sunshade experience high wind blew, powerful air-flow upwards blew umbrella cloth under umbrella, also can't fast and effeciently discharge via gap narrow and small between major and minor umbrella cloth, cause umbrella stand because of can't resisting resistance high wind, and the reverse upset of umbrella frame easily takes place, so the problem of protection effect difference is arranged.

For this reason, the utility model proposes a kind of sunshade with ventilation, protection effect at the shortcoming of the ventilation sunshade existence of above-mentioned multi-layer umbrella cloth structure.

To achieve these goals, the utility model adopts following technical scheme: this sunshade comprises umbrella stand and umbrella cloth, wherein umbrella stand is made up of a umbrella bar, number main umbrella skeleton, number side umbrella frame, and the multi-layer umbrella cloth of being made up of main chute cloth, secondary umbrella cloth covers and forms one cover face on umbrella stand, it is characterized in that:
