The present invention relates to a folding shade device and, more particularly, to a 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 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 folding shade devices is necessary.
To solve the above problem, an objective of the present invention is to provide a 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.
A folding shade device according to the present invention includes a support, a rotating shaft, an adjusting shaft and a shade. The support includes first and second mounting units. The first mounting unit includes a first engagement portion and the second mounting unit includes a second engagement portion. The rotating shaft is rotatably engaged with the first engagement portion of the first mounting unit. The 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 rotating shaft. The second end of the adjusting shaft is rotatably engaged with the second engagement portion of the second mounting unit. The shade has a first end configured to be fixed around the rotating shaft and the adjusting shaft, and a second end configured to be fixed to a weight.
Thus, since the adjusting shaft of the 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 folding shade device can be easily adjusted, providing convenience in installation and use.
In an example, the rotating shaft includes a tube and a spring beam received in the tube. The spring beam includes a spring engagement portion rotatably engaged with the first engagement portion of the first mounting unit.
In an example, the spring beam further includes a rod and a spring receiving the rod. The rod includes a first connector and a second connector respectively at two ends thereof. One end of the spring is relatively adjacent to the first connector and another end of the spring is relatively adjacent to the second connector.
In an example, an outer periphery of the spring engagement portion forms a plurality of projections respectively engaged with a plurality of grooves formed on an inner periphery of the tube.
In an example, the folding shade device further includes a plug having a shaft engagement portion engaged with the second engagement portion of the second mounting unit.
In an example, the shaft engagement portion is pivotable relative to the adjusting shaft.
In an example, the rotating shaft is made of metal.
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 engaged with the second mounting unit 12. 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 rotating shaft 2. Furthermore, an outer diameter of the adjusting shaft 3 is equal to 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 shade 5 includes a first end configured to be fixed around the rotating shaft 2 and the adjusting shaft 3, and a second end configured to be fixed to the weight 6. The weight 6 can be in the form of a cylindrical member to provide an aesthetic appearance. Thus, when the rotating shaft 2 and the adjusting shaft 3 rotate, the shade 5 can be coiled upward or pulled downward to an extended state.
With reference to
By providing the above structure, in the installation of the folding shade device according to the present invention, since the adjusting shaft 3 is made of a non-metal material and is, thus, easy to cut, the user can use a cutting tool, that is simple or that can be easily obtained, to cut the adjusting shaft 3 according to the desired length. Then, the rotating shaft 2 is fitted with the coupling portion 31 of the adjusting shaft 3. Thus, the size of the folding shade device can be easily adjusted.
Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
