Description

Umbrella with roll-over type elastic umbrella cover

Technical Field

The invention relates to an umbrella, in particular to an umbrella with a rolling type elastic umbrella cover.

Background

The umbrella is a common living tool and has very important function in rainy and snowy weather. However, most umbrella covers are cylindrical plastic or cloth films independent of the umbrella body, are easy to lose and lack of aesthetic feeling, and cause the problem that umbrella covers are easy to dirty and weather.

And after the umbrella is used in rainy and snowy days, the umbrella is wet and is inconvenient to place when dripping water.

In response to the above problems, many have proposed patent designs which are mainly divided into two categories: one type is a packaging bag or a packaging bottle independent of an umbrella body, and through the design of the appearance and the sealing performance of the bag body or the bottle body, the design solves the problems that an umbrella cover is not attractive and a wet umbrella is not easy to place, but the problem that the umbrella cover is easy to lose cannot be solved; the umbrella is characterized in that the umbrella cover is connected with the umbrella handle through a connecting rod, and the connecting rod is connected with the umbrella handle through a connecting rod.

Disclosure of Invention

Aiming at the defects that the umbrella cover is easy to lose, a wet umbrella is not easy to place, the design structure of the prior patent is complex, and the like, the invention provides the umbrella with the rolling type elastic umbrella cover.

In order to achieve the purpose, the invention adopts the following technical scheme:

an umbrella with a rolling type elastic umbrella cover comprises an umbrella end screw (1), an elastic umbrella cover (2), an umbrella body (3) and an umbrella handle (4).

Furthermore, the umbrella cover (2) is arranged at the top end of the umbrella body (3) through an umbrella end screw (1); the umbrella handle (4) is arranged at the bottom end of the umbrella body (3). The umbrella body (3) is a manually opened and closed folding umbrella or an automatically opened and closed folding umbrella which is already popular; the elastic umbrella cover (2) is made of high-elasticity material and is cup-shaped as a whole. The wall of the umbrella cover is thin, so that the wall of the umbrella cover can only deform and hardly generate elasticity when being rolled, but the thickness of the wall of the umbrella cover is enough to protect the umbrella body and resist damage; the opening of the umbrella cover is of a rubber ring structure, and compared with the umbrella cover wall, the thickness of the rubber ring structure is larger, so that enough elastic force can be generated when the rubber ring structure deforms along the circumference; the umbrella cover bottom is a bowl-shaped structure with a ring groove, and the direction of the bowl opening is opposite to the direction of the integral cup opening. Compared with the umbrella cover opening rubber ring structure, the rigidity of the ring groove is higher, so that after the umbrella cover is rolled and embedded into the ring groove, the deformation of the ring groove is small. The outer surface of the umbrella handle (4) is a stepped shaft consisting of two cylinders, namely, the stepped shaft is provided with a shaft shoulder structure, the diameter of the large shaft of the stepped shaft is larger than the inner diameter of the rubber ring structure of the elastic umbrella sleeve (2), and the diameter of the small shaft of the stepped shaft is smaller than the inner diameter of the rubber ring structure.

Furthermore, when the umbrella is not opened, the umbrella cover is sleeved on the folded umbrella body, and the rubber ring at the opening of the umbrella cover is buckled on the shaft shoulder of the umbrella handle due to the elastic action; when in use, the rubber ring is pushed out from the shaft shoulder, and the cup-shaped umbrella cover is turned to the umbrella end along the axial direction of the umbrella body to form a ring shape. Because the very thin umbrella cover wall can only deform and hardly generate elasticity when being rolled, and the rubber ring structure still has enough shrinkage elasticity after being rolled, the completely rolled umbrella cover can be embedded into the ring groove under the shrinkage force of the rubber ring structure, and can not be automatically bounced open under the friction force between the rolled umbrella cover layers and the auxiliary action of the ring groove. The reverse bowl-shaped structure at the bottom of the umbrella cover can not only help the completely rolled umbrella cover to be incapable of bouncing open by itself, but also ensure that the completely rolled umbrella cover can not wrap the top of the umbrella body. When the umbrella cover is rolled to the bottom and embedded into the annular groove, the folding umbrella can be unfolded; after the umbrella is folded after use, the rolled umbrella cover is unfolded into a cup shape along the axis of the umbrella body, and the rubber ring structure is buckled on the shaft shoulder of the umbrella handle to complete the packaging of the umbrella. If the umbrella is used in rainy days, the rainwater can be sealed in the umbrella cover after the umbrella is packaged, and the problem that a wet umbrella is inconvenient to place is solved.

The invention has the following characteristics: firstly, the umbrella cover and the umbrella body are integrated, so that the problem that the umbrella cover is easy to lose is solved; secondly, because the contact between the umbrella cover layer after the roll-over is close, rainwater can not enter, so use the nearly anhydrous on the umbrella cover, will make used wet umbrella pack, has solved the umbrella and has wet the inconvenient problem of placing. Moreover, the design of certain patterns and shapes is carried out on the umbrella cover, so that the aesthetic degree of the umbrella can be increased. In addition, the device has the advantages of simple structure, convenient operation, difficult damage, low cost and easy popularization.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, an umbrella with a rolling elastic umbrella case according to the present invention comprises: an umbrella end screw (1), an elastic umbrella cover (2), an umbrella body (3) and an umbrella handle (4).

As shown in figure 2, the opening of the umbrella cover is provided with an elastic rubber ring structure with the inner diameter slightly smaller than the diameter of the shaft shoulder of the umbrella handle. The thickness of the rubber ring structure is far greater than that of the umbrella sleeve wall, so that the rubber ring structure has enough elasticity to be buckled on the umbrella handle and still has enough contraction elasticity after being rolled, and the umbrella sleeve wall hardly generates elasticity during rolling; as shown in figure 3, the diameter of the shaft shoulder on the umbrella handle is larger than the inner diameter of the rubber ring, so that the rubber ring is tightly buckled on the umbrella handle, and the purposes of non-slip connection, good sealing and moderate elasticity during rolling are achieved.

As shown in fig. 4, when the umbrella is not opened, the umbrella cover is sleeved on the folded umbrella body, and the rubber ring at the opening of the umbrella cover is buckled on the shaft shoulder of the umbrella handle due to the elastic action; when in use, the rubber ring is pushed out from the shaft shoulder, and the cup-shaped umbrella cover is turned to the top end of the umbrella into a ring shape along the axial direction of the umbrella body. Because the very thin umbrella cover wall can only deform and hardly generate elasticity when being rolled, the completely rolled umbrella cover can be embedded into the ring groove under the action of the shrinkage force of the rubber ring structure, and can not be automatically bounced open under the friction force between the rolled umbrella cover layers and the auxiliary action of the ring groove. The reverse bowl-shaped structure at the bottom of the umbrella cover can not only help the completely rolled umbrella cover to be incapable of bouncing open by itself, but also ensure that the completely rolled umbrella cover can not wrap the top of the umbrella body. When the umbrella cover is turned to the bottom, the folding umbrella can be unfolded; after the umbrella is folded after use, the rolled umbrella cover is unfolded into a cup shape along the axis of the umbrella body, and the rubber ring structure is buckled on the shaft shoulder of the umbrella handle to complete the packaging of the umbrella.

The foregoing description is only exemplary for the purpose of illustrating the principles and features of the invention, and is not intended to limit the invention to the particular forms or embodiments disclosed herein, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
