Abstract

The utility model relates to an umbrella, which comprises an umbrella rod, a spoke, an umbrella frame and an umbrella surface. The umbrella is characterized in that the umbrella rod is provided with a specific eccentric device. The end heads of the upper section and a flat milling part of the lower section of the eccentric device are provided with two vertical positioning tapered holes, and the umbrella rod not only can be positioned at the center of the umbrella, but also can offsets the center via the eccentric device. The utility model is an eccentric umbrella.

Description

Eccentric umbrella

The utility model is a kind of en-toutcas, and it comprises umbrella bar, spoke, umbrella frame, umbrella cover.

At present the en-toutcas that uses all is that the umbrella bar is positioned at umbrella central authorities, and the user can only hold the edge that the umbrella bar stands in umbrella, outside being easy to health is exposed to, can not effectively utilize the coverage rate sunshade of umbrella and takes shelter from rain, and allows the people feel very inconvenient, and this is the disadvantage that has umbrella now.In order to address this problem, in patent documentation on the books, the designer attempts by change width of cloth bar length, or designs ellipse garden shape umbrella and solve this problem, and in addition, also the someone has designed " the curved umbrella of hanging ", " multipurpose eccentric umbrella "." the curved umbrella of hanging " requires the umbrella rod bending, changes spoke length and must be equipped with special beak fastener and could realize its purpose; " multipurpose eccentric umbrella " will utilize the triangle stability principle in the umbrella rod bending, and is equipped with the locking device of hot investment casting, could realize that it is eccentric and stable.The manufacturability of " the curved umbrella of hanging ", " multipurpose eccentric umbrella " is not so good, makes inconvenience, and practicality is relatively poor.

The purpose of this utility model provides a kind of novel en-toutcas, and it not only has the function of existing en-toutcas, and can remedy the deficiency of existing umbrella more effectively for the user provides umbrella coverage rate to greatest extent.

The utility model is achieved in that at the first half of umbrella bar loads onto an eccentric, and this device is by unclamping of connecting of taper pin and locks the bending that realizes the umbrella bar, stretches and fix.Upper umbrella rod makes umbrella bar Lower Half depart from umbrella central authorities after bending, moves to the edge of umbrella, and the user has just occupied the middle position under the umbrella cover like this.When eccentric stretched the umbrella bar, the umbrella bar just was positioned at the central authorities of umbrella again.

The eccentric that the utility model provides, compared with former eccentric, make the umbrella rod bending and stretch the function except finishing, biggest advantage is that also the manufacturability of this eccentric is better, both the also available engineering plastics of available metal were produced in enormous quantities, and the appearance and size of this eccentric is less, and weight is also light, has alleviated user's burden.Therefore, the utility model has improved the practicality of umbrella really.

Contrast Fig. 1, Fig. 2 below, Fig. 3, Fig. 4 are described in detail the utility model.

Schematic appearance when Fig. 1 realizes the umbrella rod bending for the utility model.

Fig. 2 is the front view of eccentric in the utility model.

Fig. 3 is the vertical view of eccentric in the utility model.

Fig. 4 is the cutaway view of pull bar present position in the eccentric.

As shown in Figure 2, eccentric is made up of epimere (1), stage casing (2), spring (3), garden post taper pin (4), pull bar (5), hypomere (6), mandrel (7), and wherein epimere (1) is identical on structure and size with hypomere (6).Epimere (1) is a garden post shapes, one end end is processed into half garden shape and is milled flat, the center that plat mill part divides is drilled with the through hole of assembling mandrel (7), and there are two orthogonal location taper holes the termination that plat mill part divides, the outer garden diameter of the other end of epimere is slightly smaller than its middle part diameter, is convenient to be connected with the first half of umbrella bar.Stage casing (2) also is a garden post shapes, its two-end structure is just the same, half garden shape all is processed in the end, and mill the groove that a width is slightly larger than the flat end width of epimere (1), be convenient to the insertion and the rotation of the point of shoulder of epimere (1), two ends, stage casing (2) are drilled with the through hole of assembling mandrel (7), are drilled with blind hole at its termination axis direction in addition, so that spring of packing into (3) and garden post taper pin (4); The both sides at place, two ends, stage casing (2) also mill out a facet, are processed with elongated slot above, and elongated slot communicates with the blind hole of termination, stage casing (2) axis direction.The front end of garden post taper pin (4) is the taper pin shape, and latter half is the garden shell of column, and an aperture is arranged on the shell of column of garden, and the center line of aperture is perpendicular to the axial line of garden shell of column.During assembling, in the blind hole of stage casing (2) axis direction of earlier spring (3) being packed into, reinstall garden post taper pin (4), from the elongated slot of stage casing (2) end sides, insert pull bar (5) then, pull bar (5) passes the aperture on the shell of column of garden post taper pin (4) garden, and two end face is exposed at the elongated slot outside of side, two ends, stage casing (2), is convenient to pulling moving pull bar (5), point of shoulder with epimere (1) inserts in the end grooves in stage casing (2) at last, penetrates mandrel (7) again.Equally, stage casing (2) also are like this with the assembly method of hypomere (6).During use, as long as with hand pull bar (5) is drawn along the holddown spring direction, pull bar (5) just drives garden post taper pin (4) and retreats, and the location taper hole of epimere (1) end is just withdrawed from the end of its taper pin shape, and epimere (1) just can rotate around mandrel (7).The user just can remove epimere (1) to selected angle (make the umbrella rod bending or when stretching angle) and decontrol pull bar (5) then, like this, garden post taper pin (4) is just under the elastic force effect of spring (3), automatically insert in the location taper hole of epimere (1) end, realize the locked and fixing of epimere (1) and stage casing (2), because epimere mills the termination of shoulder portion two orthogonal location taper holes are arranged, stretching or position crooked 90 ° the time can be locked and fixing so also just guaranteed the umbrella bar.Equally, stage casing (2) also are same method with the angle Selection of hypomere (6) with fixing.In sum, the eccentric that adopts the utility model to provide really can realize more satisfactoryly the umbrella bar bending, stretch and fix, make the umbrella bar can be positioned at the edge of umbrella, can be positioned at the central authorities of umbrella again, improved the Practical Performance of umbrella.
