Patent Application
20150129142
The present invention relates to a curtain structure, and more particularly to a stringless curtain structure.
Conventional curtains, such as Venetian blinds, roller blinds and Roman blinds are equipped with a string for the user to pull to control the movement of the curtain to provide shade, privacy and many other decorative purposes. However, the string of conventional curtains are usually of the shape of a closed circle and exposed outside the curtain, so when little children play near the curtain or play the string, the string is prone to entangle the child's neck to cause strangulation death. Therefore, there remains a need for a new and improved stringless curtain structure to overcome the problems stated above.
The string of conventional curtains are usually of the shape of a closed circle and exposed outside the curtain, so when little children play near the curtain or play the string, the string is prone to entangle the child's neck to cause strangulation death.
To solve the problems stated above, the present invention provides a stringless curtain structure may include a curtain body, a string rolling mechanism and two breaking units. The curtain body has an upper beam having a receiving space, and a curtain is connected to a bottom portion of the upper beam, and a weighted lower beam is disposed at a bottom portion of the curtain. The string rolling mechanism has a base having a base receiving space, and a string rolling space is located on both sides of the base receiving space. A string opening is formed at an outer wall of the string rolling space, and a spring is disposed at the base receiving space of the base. Furthermore, a conjugating portion is formed at one side of the base receiving space to secure and position the spring. A gear is disposed at center of the spring through a shaft, and a rolling gear is disposed at each of the string rolling space, and one end of string is secured at the rolling gear. Surface of the rolling gear has a connecting gear to drive the gear and a driving gear, and a cover is provided to cover the base with the base receiving space and the string rolling space. Two breaking units are disposed on both sides of the receiving space of the upper beam, having at least three parallel staggered rods, so the string is configured to be twined in the breaking unit from the string rolling mechanism, connected with the curtain and secured at the weighted lower beam.
The present invention is advantageous because the weight of the spring and the weighted lower beam is balanced, the user can push/pull the weighted lower beam to control the curtain to eliminate the exposure of the string, so little children would not play with the string to lead to dangerous situation. Furthermore, the breaking unit is disposed at each sides of the string rolling mechanism, so when the curtain needs to be positioned, the friction between the string and the breaking units can be used to enhance the precision of the positioning of the curtain body.
The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.
All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention.

Furthermore, when the user wants to restore the curtain 12 to the curtain body 10, referring to
According to the embodiments described above, the present invention is advantageous because the weight of the spring 24 and the weighted lower beam 13 is balanced, the user can push/pull the weighted lower beam 13 to control the curtain 12 to eliminate the exposure of the string, so little children would not play with the string to lead to dangerous situation. Furthermore, the breaking unit 30 is disposed at each sides of the string rolling mechanism 20, so when the curtain 12 needs to be positioned, the friction between the string 14 and the breaking units 30 can be used to enhance the precision of the positioning of the curtain body 10.
Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
