The present invention relates to the technical field of umbrellas, particularly to the technical field of sunshade umbrellas, and more particularly to an effortless unfolding structure of sunshade umbrella which facilitates to unfold the umbrella in a labor-saving way.
Nowadays, sunshade umbrellas can be seen everywhere. Some types of the sunshade umbrellas have effortless unfolding structures, while similar existing products on the market are all provided with external gas springs to achieve the effortless unfolding of the umbrellas. The drawback of these products lies in the destroyed overall appearance, the high cost and being subjected to the limitation of gas springs. Moreover, the Chinese patent ZL 97249802.8 has disclosed an elastic pipe clip for umbrella rib, which could clamp onto the umbrella rib and hinge with branching ribs, and on which springs mounted resists against the branching ribs. Thus while opening the umbrella with such elastic pipe clip, the branching ribs receive release force from spring and stretch out for unfolding the umbrella in a quick and effortless way. But the drawback of harm in the whole appearance also exists in this structure.
Thus, in order to solve the abovementioned problems and drawbacks, an effortless unfolding structure of sunshade umbrellas needs to be provided. It is effortless to unfold the umbrella and the whole appearance will not be affected.
The object of the present invention is to provide an effortless unfolding structure of sunshade umbrella for overcoming above drawbacks in prior art. The effortless unfolding structure of sunshade umbrella is ingeniously designed, concise in structure and can facilitate to open umbrella in a labor saving way. Also, the whole appearance will not be affected and it is appropriate to be promoted and applied on a large scale.
In order to achieve the abovementioned object, the present invention provides an effortless unfolding structure of sunshade umbrella comprising a cantilever, a pulling rope, an elastic component and a fixing block, wherein pulling rope comprises a first end part and a second end part. Said second end part, said elastic component and said fixing block are all arranged inside said cantilever. Said first end part passes through the end face of said cantilever and said second end part is fixed to said fixing block. Said elastic component is arranged between the end face of said cantilever and said fixing block with its two ends resisting against the end face of said cantilever and said fixing block respectively.
Preferably, said elastic component is a spring and said spring sleeves outside said pulling rope.
Preferably, said fixing block is an end face snap-fit piece.
More preferably, said pulling rope is a steel wire rope, and said end face snap-fit piece is applied for the steel wire rope.
Preferably, the effortless unfolding structure of sunshade umbrellas also comprises a bearing component for the pulling rope, and said first end part winds part of said bearing component for the pulling rope.
More preferably, said bearing component for the pulling rope is a bearing block with a groove, and said first end part winds part of said groove.
More preferably, the effortless unfolding structure of sunshade umbrellas also comprises a fixing block for the oblique rods. Said bearing component for the pulling rope is mounted on the fixing block for the oblique rods, and said first end part is fixed on said fixing block for the oblique rods.
Further, said bearing component for the pulling rope and said fixing block for the oblique rods are integrally formed.
Further, the effortless unfolding structure of sunshade umbrellas also comprises a locking plate. Said fixing block for the oblique rods is fixed on the post of the sunshade umbrella by means of said locking block.
The advantages of the present invention lie in: the effortless unfolding structure of sunshade umbrellas of the present invention comprises a cantilever, a pulling rope, an elastic component and a fixing block; said pulling rope comprises a first end part and a second end part; said second end part, said elastic component and said fixing block are all arranged inside said cantilever; said first end part threads through the end face of said cantilever and said second end part is fixed to said fixing block; said elastic component is arranged between the end face of said cantilever and said fixing block with its two ends resisting against the end face of said cantilever and said fixing block respectively; during the installation, The cantilever is mounted between the two oblique rods which support the umbrella frame; the first end part of the pulling rope is mounted on the post of the sunshade umbrella, and thus making use of the relative movement of the oblique rods relative to the post; the pulling rope pulls the fixing block to compress the elastic component for storing energy to unfold the umbrella. It is ingeniously designed, concise in structure and can facilitate to open umbrella in a labor saving way; also the whole appearance will not be affected and it is appropriate to be promoted and applied on a large scale.
In order to understand the technical content of the present invention more clearly, the following embodiments is exemplified to be described in details. It should be understood that the embodiment should be considered as illustrative rather than restrictive.
Please refer to
The elastic component 3 can be any appropriate component. Please refer to
Said fixing block 4 can be any appropriate component. Preferably, the said fixing block 4 is an end face snap-fit piece. Please refer to
In order to facilitate the pulling rope 2 to displace relative to the cantilever 1, preferably, said effortless unfolding structure of sunshade umbrella also comprises a bearing component 5 for the pulling rope. The said first end part 21 winds part of the said bearing component 5. Said bearing component 5 can be of any appropriate structure. Please refer to
The oblique rod 10 of the sunshade umbrella can be fixed to the post 20 by any appropriate ways. Preferably, the said effortless unfolding structure of sunshade umbrella also comprises a fixing block 6 for the oblique rods. Said bearing component 5 for the pulling rope is mounted on the said fixing block 6 for the oblique rod. Said first end pat 21 is fixed on the said fixing block 6 for the oblique rods. The oblique rods 10 are pivotally connected with the fixing block 6 and the fixing block 6 is fixed on the post 20.
Said bearing component 5 for the pulling rope can be mounted on said fixing block 6 for the oblique rod; or otherwise, said bearing component 5 for the pulling rope and said fixing block 6 for the oblique rods can be formed integrally. Please refer to
Said fixing block 6 for the oblique rods can be fixed to the post 20 of the sunshade umbrella in any appropriate structures. Please refer to the
Refer to
Refer to
To sum up, the effortless unfolding structure of sunshade umbrella is ingeniously designed, concise in structure, and can facilitate to open umbrella in a labor saving way. The overall appearance will not be damaged. It is suitable to be promoted and applied on a large scale.
