The present invention relates to an electric folding shade device and, more particularly, to an electric folding shade device including components that can be easily and conveniently cut by a user according to the desired size.
The transmission member 913 drives the shaft 92 to rotate. Thus, the shaft 92 must be made of rigid metal to permit synchronous rotation of the shaft 92 and the transmission member 913 without the risk of loosening, thereby assuring subsequent folding or unfolding of the shade 93.
A user installing the electric folding shade device 9 can purchase in a shopping mall the desired components according to personal favorites, styles, colors, or the decoration atmosphere. The user can cut the components to the desired sizes meeting a size of a window in a house. However, most families do not have a machine for cutting the shaft 92 which is generally made of metal. Thus, the user must ask help from a factory or a shop, which is extremely inconvenient in use.
Thus, improvement to the conventional electric folding shade devices is necessary.
To solve the above problem, an objective of the present invention is to provide an electric folding shade device including components that can be easily and conveniently cut by a user according to the desired size.
When the terms “up”, “down”, “inner”, “outer” and similar terms are used herein, it should be understood that these terms have reference only to the structure shown in the drawings as it would appear to a person viewing the drawings and are utilized only to facilitate describing the invention, rather than restricting the invention.
An electric folding shade device according to the present invention includes a support in a form of a beam having a first end and a second end. A driving element and a transmission member are mounted to the first end of the support. The driving element drives the transmission member to rotate. A rotating shaft includes a first end coupled to the transmission member and a second end. An adjusting shaft is made of a non-metal material and includes a first end and a second end. The first end of the adjusting shaft is fitted with the second end of the rotating shaft. The adjusting shaft further includes a second end rotatably mounted to the second end of the support. A roller in a form of a hollow tube is fitted with the rotating shaft. A shade includes a first end adapted to be fixed to the roller and a second end adapted to be fixed to a weight.
Thus, since the adjusting shaft of the electric folding shade device according to the present invention is made of a non-metal material, the user can use a cutting tool, that is simple or that can be obtained easily, to cut the adjusting shaft according to the desired length. After cutting. The adjusting shaft is coupled to the rotating shaft. Thus, the size of the electric folding shade device can be easily adjusted, providing convenience in installation and use.
In an example, two seats are respectively coupled to the first end and the second end of the support to provide convenient assembly.
In an example, the support further includes a groove extending from the first end through the second end of the support, and each of the two seats includes a connecting portion detachably coupled in the groove of the support, providing convenient assembly.
In an example, one of the two seats fixed to the second end of the support includes a positioning portion, and the second end of the adjusting shaft is rotatably mounted to the positioning portion, providing convenient assembly.
In an example, the rotating shaft includes an engaging portion engaged with the transmission member to assure rotational smoothness.
In an example, adjusting shaft includes a second fixing member, and the rotating shaft and the adjusting shaft are fixed together by the second fixing member. This enhances the coupling effect between the rotating shaft and the adjusting shaft.
In an example, the rotating shaft and the adjusting shaft are fixed together by a connecting member to provide convenient connection.
In an example, the connecting member includes a first end fitted with the second end of the shaft and a second end fitted with the first end of the adjusting shaft, providing convenient connection.
In an example, the adjusting shaft includes two second fixing members. The rotating shaft and connecting member are fixed by one of the two second fixing members. The adjusting shaft and the connecting member are fixed together by the other of the two second fixing members.
In an example, the adjusting shaft is made of a paper roll or plastic to permit easy cutting.
The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.

The second end of the adjusting shaft 3 is rotatably mounted to the positioning portion 16 at the second end of the support 1. The first end of the adjusting shaft 3 includes a coupling portion 31 fitted with the second end of the rotating shaft 2. The coupling portion 31 can be fitted with an inner periphery or an outer periphery of the rotating shaft 2. In this embodiment, the coupling portion 31 is fitted in the adjusting shaft 3. Furthermore, an outer diameter of the adjusting shaft 3 is the same as an outer diameter of the rotating shaft 2. It is noted that the adjusting shaft 3 is made of a non-metal material, such as a paper roll or plastic. Thus, the user can easily and conveniently cut the adjusting shaft 3 to the desired length.
The roller 4 is coupled with the rotating shaft 2 and can be in the form of a hollow tube fitted with the rotating shaft 2, such that the roller 4 and the rotating shaft 2 rotate synchronously. A shade 41 includes a first end adapted to be fixed to the roller 4 and a second end adapted to be fixed to a weight 42. The weight 42 can be in the form of a cylindrical member to provide an aesthetic appearance. Thus, when the rotating shaft 2 rotates, the shade 41 can be coiled upward or pulled downward to an extended state. Specifically, the roller 4 is also made of a non-metal material to permit cutting by the user to the desired length.
