Description

Rolling shutter structure and manufacturing method thereof

The present invention relates to a roller blind structure and a manufacturing method thereof, in particular, an action of directly applying a force to a curtain surface for pulling down or pushing up during use, so that the curtain surface is lowered or raised by using an elastic unit with a user's force. Operation to achieve ease of operation and better safety.

The conventionally used roller blind (such as a roman shade) comprises an upper beam, a lifting unit, and a curtain surface connected to the bottom of the upper beam. The lifting unit has a plurality of pulling ropes and lifting ropes. The curtain surface is formed by connecting a plurality of lateral sagging sections, and at least one row of perforations are provided on the lateral sagging section for the lifting rope to pass through and is fixed on the lowermost perforation; thereby pulling the pulling The rope causes the lifting rope to move the curtain surface to achieve the action of ascending and descending.

However, since the general roller blind is in the action of ascending and descending, and the pull rope of the general roller blind is normally exposed on one side of the curtain, the child will be curious or playful. The pulling rope is wound around the neck, and an accident such as a neck is generated, which poses a major safety threat to the child.

Therefore, how to create a roller blind structure and its manufacturing method to make it easy to operate and have better safety will be actively exposed by the creative.

In view of the above-mentioned shortcomings of the conventional roller blind structure and its manufacturing method, the creator feels that he has not perfected it, exhausted his mind and researched and overcome it, and developed a roller blind with his accumulated experience in the industry for many years. The structure and its manufacturing method are intended to achieve easy operation and better safety.

The main purpose of the present invention is to provide a roller blind structure and a manufacturing method thereof, which can directly pull a force on a curtain surface to perform a pull-down or push-up action, so that the curtain surface is reduced by the elastic unit and the user's force. Or the ascending operation, thereby achieving the purpose of easy operation and better safety.

In order to achieve the above object, the present invention relates to a roller blind structure and a manufacturing method thereof, the structure comprising a roller blind body having a shaft and a curtain; an elastic unit having a hinge, a fixed shaft and a resilient member; and a first fixing seat And a second fixing seat; and the manufacturing unit is configured to set the hinge of the elastic unit to one end of the rod body, and the fixed shaft system is movably coupled with the rotating shaft, and the two ends of the elastic element are respectively coupled to the rotating shaft and Fixing the shaft, combining the first fixing seat with the fixed shaft, and finally combining the second fixing seat with the other end of the rod body.

In an embodiment of the present invention, the other end of the curtain is provided with a weight portion, and the weight portion is provided with a pulling portion.

In one embodiment of the present invention, the hinge device includes a receiving tray for arranging the elastic member, a fixing post extending to one side of the receiving tray and coupled to one end of the rod body, and a fixing bracket disposed on the receiving tray. A hollow tube that communicates with the fixed column and is movably coupled to the fixed shaft, and one end of the elastic element is coupled to the outer edge of the hollow tube.

In one embodiment of the present invention, the fixed shaft system includes a cover plate having a closed elastic member and an inner edge coupled to the other end of the elastic member, a shaft body extending from one side of the cover plate and movably coupled to the shaft member, and a shaft a positioning portion fixed to the other surface of the cover and fixed to the first fixing base.

In one embodiment of the present invention, the elastic element can be a constant force spring.

Therefore, the roller blind structure and the manufacturing method thereof of the present invention can directly exert a force on the curtain surface to perform a pull-down or push-up action when the user uses the elastic unit to cooperate with the user's force as a drop or rise. The operation is easy to operate and has better safety.

In order to fully understand the purpose, features and effects of this creation, the following specific examples, together with the attached drawings, provide a detailed description of the creation, as explained below: please refer to "1st and 2nd drawings" 』, is the external view of the creation and the exploded view of the creation. As shown in the figure: the roller blind structure of the present invention and the manufacturing method thereof comprise a roller blind body 1 comprising a rod body 11, a curtain surface 12, a weight portion 13 and a pulling portion 14, and the elastic unit 2 comprises The hinge 21, the fixed shaft 22 and the elastic member 23, the first fixing base 3 and the second fixing base 4.

It is produced in the following steps:

Step a: Take a roller blind body 1 having a shaft 11 and a curtain surface 12. One end of the curtain surface 12 is disposed on the outer side edge of the rod body 11, and the other end of the curtain surface 12 is provided with a weight portion 13. A pull portion 14 can be disposed on the weight portion 13.

Step b: an elastic unit 2 is disposed at one end of the rod body 11, and the shaft unit 21 is coupled to one end of the rod body 11. The fixed shaft 22 is movably coupled with the shaft member 21, and the two ends of the elastic member 23 are respectively The rotator 21 includes a accommodating disc 211 for arranging the elastic member 23, a fixing post 212 extending to one side of the accommodating disc 211 and coupled to one end of the rod body 11, And a hollow tube 213 disposed on the other side of the accommodating disc 211 and communicating with the fixing post 212 and engaging with one end of the elastic member 23, and the fixing shaft 22 includes a closed elastic member 23 and the inner edge is combined with the elastic member 23 at the other end. The cover plate 221, a shaft body 222 extending from one side of the cover plate 221 and movably coupled to the hollow tube 213, and a positioning portion 223 disposed on the other surface of the cover plate 221, wherein the elastic element 23 can be a constant force spring .

Step c: Combining the first fixing base 3 with the positioning portion 223 of the fixed shaft 22.

Step d: The second fixing base 4 is further combined with the other end of the rod body 11.

Please refer to "3rd and 4th drawings" for the usage status diagram of the creation and the action diagram of the creation elastic unit. As shown in the figure: When the creation is assembled (please refer to Figures 1 and 2 at the same time), the first fixing seat 3 and the second fixing seat 4 can be fixed above the window frame, and the system is used. Applying the force directly to the weight portion 13 or the pulling portion 14 of the curtain surface 12, and causing the curtain surface 12 to rotate the rod body 11, and the fixed shaft 22 of the elastic unit 2 is still stationary. The shaft 21 is rotated by the hollow tube 213 on the shaft 222 of the fixed shaft 22, thereby driving the elastic element 23 to reverse, so that the elastic element 23 offsets the vertical weight of the weight portion 13 by the reversed elastic force. The balance is pulled to lower the curtain 12, and when the curtain 12 is wound up, the weight portion 13 is pushed upward, so that the vertical weight of the weight portion 13 disappears when pushed up, thereby The resilient member 23 is returned to its original shape so that the curtain 12 can be pulled up to achieve ease of handling and better safety.

As mentioned above, this creation is fully in line with the three requirements of the patent: novelty, advancement and industrial applicability. In terms of novelty and advancement, the creation uses the action of directly applying force to the curtain surface to pull down or push up, so that the curtain uses the elastic unit to cooperate with the user's force as a downward or ascending operation. In turn, it achieves the utility of being easy to operate and having better security; in terms of industrial availability, the products derived from the creation can fully satisfy the needs of the current market.
