Patent Application

The present invention relates to a retarding structure for rolling a curtain and a manufacturing method thereof, in particular to a structure and a method capable of preventing the curtain from being damaged and providing a universal application.
Traditional curtain (such as Roman curtain) generally includes a curtain rod, an elevating unit, a curtain fabric coupled to the bottom of the curtain rod, and an automatic rolling mechanism installed in the curtain rod and coupled to the curtain fabric, such that an effect of rolling up the curtain fabric automatically can be achieved.
Since the automatic rolling mechanism almost has no resistance, a larger instant rolling force will be produced when the curtain fabric is rolled up by the automatic rolling mechanism, and the curtain may be damaged easily due to excessive collisions. To overcome the aforementioned drawback, manufacturers have developed various different retarding mechanisms to prevent the curtain fabric from being rolled up instantly. However, the retarding mechanisms available in the market require an installation of the automatic rolling mechanism, such that the retarding mechanisms cannot be used in a curtain without a retarding structure, and users have to change the whole set of curtain before overcoming the problem of the curtain fabric being rolled up instantly. Obviously, the traditional retarding mechanisms provide a poor universal application and incur a waste of resources.
Therefore, it is an important subject of the present invention to provide a retarding structure for rolling a curtain and a manufacturing method thereof, so as to achieve the effects of preventing the curtain from being damaged easily and providing a universal application.
In view of the aforementioned shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a retarding structure for rolling a curtain and a manufacturing method thereof to achieve the effects of preventing the curtain from being damaged easily and providing a universal application.
Therefore, it is a primary objective of the present invention to provide a retarding structure for rolling a curtain and a manufacturing method thereof, wherein a housing is coupled to any curtain rod having an automatic rolling mechanism, such that when a curtain fabric is rolled up to the curtain rod by the automatic rolling mechanism, the shaft together with the elastic element are provided for gradually increasing the resistance during the rolling process to prevent the curtain fabric from being rolled up instantly, so as to achieve the effects of preventing the curtain from being damaged easily and providing a universal application.
To achieve the foregoing objectives, the present invention provides a retarding structure for rolling a curtain and a manufacturing method thereof, and the structure comprises a housing, a shaft and an elastic element. When the retarding structure is manufactured, the shaft is movably coupled into the housing, such that an end of the shaft is extended out from the housing, and then the elastic element is sheathed onto the shaft, and both ends of the elastic element are abutted against internal walls of the housing respectively.
In the retarding structure for rolling a curtain and its manufacturing method in accordance with the present invention, the housing is combined with any curtain rod having an automatic rolling mechanism, such that when the curtain fabric is rolled up to the curtain rod by the automatic rolling mechanism, the shaft together with the elastic element are provided for gradually increasing the resistance during the rolling process to prevent the curtain fabric from being rolled up instantly, so as to achieve the effects of preventing the curtain from being damaged easily and providing a universal application.
To make it easier for the examiner to understand the objects, characteristics and effects of this invention, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
With reference to
The housing 1 comprises a bushing 11, a seal cover 12 coupled to the bushing 11, and a plurality of ribs 121 formed on an external side of the seal cover 12.
The shaft 2 is movably coupled into the housing 1, wherein an end of the shaft 2 is a front-end portion 21 extended out from the bushing 11, and another end of the shaft 2 is a rear-end portion 22 disposed on an internal side of the seal cover 12, and a middle portion 23 is formed between the front-end portion 21 and the rear-end portion 22.
The elastic element 3 is a coil spring made of a metal or plastic material, and the elastic element 3 is sheathed onto the middle portion 23 of the shaft 2, and both ends of the elastic element 3 are abutted against internal walls of the bushing 11 respectively.
With reference to
Step (a): Prepare a housing 1 having a bushing 11 and a seal cover 12.
Step (b): Install a shaft 2 into the bushing 11 of the housing 1, such that a front-end portion 21 of the shaft 2 is extended out from the bushing 11.
Step (c): Sheath an elastic element 3 onto a middle portion 23 of the shaft 2, such that both ends of an elastic element 3 are abutted against internal walls of the bushing 11 of the housing 1, and then the seal cover 12 is coupled to a distal side of the bushing 11. In addition, the front-end portion 21 of the shaft 2 is extended out from the bushing 11, and the rear-end portion 22 of the shaft 2 is disposed on an internal side of the seal cover 12, so that the shaft 2 can be movably coupled into the housing 1.
The present invention can be applied to any curtain 4 having an automatic rolling mechanism 41 (refer to
In summation of the description above, the present invention combines the housing to any curtain rod having an automatic rolling mechanism, such that when the curtain rod uses the automatic rolling mechanism to roll up the curtain fabric, the shaft together with the elastic element gradually increase the resistance during the rolling process to prevent the curtain fabric from being rolled up instantly, so as to achieve the effects of preventing the curtain from being damaged easily and providing a universal application. In addition, products derived by the method of the invention can meet the market requirements, and the present invention complies with patent application requirements, and thus is duly filed for patent application.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
