Abstract

The utility model relates to a straight rib umbrella with a square umbrella surface, which comprises the umbrella surface (1) and a plurality of groups of radial rib units. Each radial rib unit comprises main ribs (2) and supporting ribs supporting the main ribs (2). The umbrella surface (1) is a single-piece square or approximately square umbrella cloth. The main ribs (2) comprise four long main ribs (21) arranged at diagonal positions of the square umbrella surface and a plurality of short main ribs (22) between two adjacent long main ribs (21). The width of the long main ribs (21) is larger than the width of the long main ribs (21). The utility model has the advantages that the umbrella surface of the straight rib umbrella is tightened and is not apt to shake, the rib structure is firm and is not apt to shift, the assembling is simple, the cost is low, the single-piece integral umbrella surface requires no joining and the integrity of the printed patterns can be kept. The straight rib umbrella can be particularly used as manual or automatic opening straight rib advertisement umbrellas.

Description

Vertical frame umbrella with square umbrella cover

Technical field

The utility model relates to a kind of en-toutcas, relates in particular to the vertical frame umbrella that a kind of umbrella cover adopts the monolithic umbrella cloth, is applicable to the vertical frame umbrella that hand is opened or opened automatically.

Background technology

In the prior art, the umbrella cover of en-toutcas adopts circular umbrella cover usually, this circle umbrella cover is sewed up by the multi-disc umbrella cover and is formed, main bone be installed in the umbrella cover suture and by linear slit together to prevent that main diostosis from causing umbrella cover to support the inhomogeneous and tight umbrella cover that jumps, make the shape at umbrella cover applying umbrella frame top, but the suture of umbrella cover is easy to generate the phenomenon of leaking, and it is very difficult to form the pattern of an integral body at umbrella cover, the expense of not only taking a lot of work material but also poor effect.For this reason, notification number is that the Chinese utility model of CN1731492A discloses a kind of " large umbrella fabric piece advertising umbrella ", and this umbrella adopts the whole umbrella cover of monolithic, conveniently prints global pattern on umbrella cover, is particularly suitable as advertisement umbrella and uses.Yet the umbrella cover circumferential outer edge of this umbrella has the phenomenon of Dutch roll, and is easy to generate relative displacement between main bone and the umbrella cover, after being subjected to the external force effect or in rotating during rod master's bone be easy to displacement, umbrella cover can double swerve, feel very loose.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of umbrella cover to adopt the monolithic umbrella cloth and is not easy to rock the vertical frame umbrella that umbrella rib structure is firm.

The technical scheme in the invention for solving the above technical problem is, manufacture and design a kind of vertical frame umbrella with square umbrella cover, comprise: umbrella cover and organize radially umbrella frame unit, described radially umbrella frame unit comprise the main bone that supports described umbrella cover and support a support bone of described main bone more;

The umbrella cloth that described umbrella cover adopts the square of monolithic or roughly is square; Described main bone comprises four at the main bone of length of square parachute face diagonal position and the main bones of many weak points between adjacent two long main bones, and the width of the main bone of described length is greater than its thickness, and this structure makes the very stable left and right sidesing shifting that is difficult for of umbrella frame.

Equally, the width of the main bone of described weak point is greater than its thickness.

The cross section of main bone of described length and short main bone can be rectangle, trapezoidal, H shape, U type or D type.

The main bone of described weak point preferably adopts 8, is provided with two main bones of weak point that length is identical between adjacent two long main bones, and is more convenient when assembling like this, is difficult for causing confusion.

Described umbrella cover can be square or roughly be square, and the length of described four long main bones is identical and cross section is identical, and the length of all 8 main bones of weak point is identical and cross section is identical.

Perhaps, described umbrella cover is rectangle or roughly is rectangle, and the length of described four long main bones is identical and cross section is identical.

Compare with prior art, the vertical frame umbrella that the utlity model has square umbrella cover has following advantage:

1, umbrella cover adopts the monolithic umbrella cloth, the whole pattern of convenient printing, and can prevent to leak;

2, the umbrella cover umbrella frame that can tightly jump is difficult for rocking, and the umbrella cover edge can Dutch roll, good looking appearance;

3, side displacement partially about umbrella rib structure is not firmly understood;

4, simple in structure, assembling is very convenient quick.

The specific embodiment

Be described in further detail below in conjunction with the embodiment shown in the accompanying drawing.

As shown in Figure 1, the vertical frame umbrella that the utlity model has square umbrella cover comprises umbrella cover 1 and organizes radially umbrella frame unit more, every group radially the umbrella frame unit include the main bone 2 that supports described umbrella cover 1 and support a support bone of described main bone 2.Wherein: described umbrella cover 1 adopts the umbrella cloth of monolithic, and its shape can be square or rectangular or roughly be square or roughly be rectangle.Described main bone 2 comprises four main bones 21 of the length in square umbrella cover 1 diagonal positions and the main bone 22 of many weak points between adjacent two long main bones 21.

In the present embodiment, described umbrella cover 1 be shaped as square, described main bone 2 has 12, and wherein four is short main bone 22 for 21,8 in long main bone, between every adjacent two long main bones 21 two main bones 22 of weak point are installed all, and the length of all four long main bones 21 is identical, and the length of all 8 main bones 22 of weak point is identical, and the order by unexpected misfortune when assembling is like this assembled, fairly simple, be not easy to cause confusion.Certainly, described umbrella cover 1 can also be rectangle, at this moment, the length of four long main bones 21 is identical, the length of two main bones 22 of weak point is also identical between adjacent two long main bones 21, but the main bone 22 of weak point that joins with the long limit of rectangle umbrella cover 1 can be longer with respect to the main bone 22 of weak point that joins with rectangle umbrella cover 1 minor face, if but the long and short limit of rectangle umbrella cover 1 be more or less the same, can adopt 8 identical main bones 22 of weak point of length to assemble equally.

The main bone 21 of described length adopts the flat bone, the width of its cross section is greater than its thickness, can adopt rectangle shown in Fig. 2 to 6, trapezoidal, H shape, U type or D type etc., its objective is the intensity that increases long main bone left and right directions, can effectively prevent long umbrella rib because of about partially the side displacement influence the support effect of umbrella cover.For identical purpose, the main bone 22 of described weak point also can adopt the flat bone of cross-sectional width greater than thickness, and what the shape of its cross section can be with long main bone 21 is identical.Assemble for convenience and unified appearance, described four long main bones 21 and/or 8 main bones 22 of weak point preferably adopt identical cross sectional shape.In addition because the length of long main bone 31 is longer, so the cross-sectional area of 4 long main bones 31 usually than 8 main bones 22 of weak point greatly to strengthen its bending strength.
