## Background
CROSS-REFERENCES TO RELATED APPLICATIONS
This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 103107548 filed in Taiwan, R.O.C. on 2014 Mar. 5, the entire contents of which are hereby incorporated by reference.
BACKGROUND
1. Technical Field
The instant disclosure relates to a wall hanger, in particular, to a wall hanging device whose position is adjustable repeatedly after hanging on a wall.
2. Related Art
Some articles in domestics or offices, like clothes, paintings, LCD screens, etc. are stored or demonstrated by hanging on the wall, via wall hanging structures or hanging devices.
A conventional hanging device is merely provided for hanging an object, like a painting or a LCD screen, on the wall. Conventionally, an object is hanged on the wall via a hook configured on the wall. Accordingly, the object is engaged with the hook or the object is hanged by the hook through a rope or a string connecting to the object. However, the object cannot be secured properly or may even fall off when the string is broken due to the gravity.
In addition, if the object is provided for demonstration and has a greater surface area, when the object is to be hanged on the wall, the orientation of the object has to be taken into consideration to ensure the object can be hanged on the wall with the right viewing angle. Accordingly, when a painting or a LCD screen is to be hanged on the wall, the position of the painting or the LCD screen has to be adjusted repeatedly until the painting or the LCD screen is well positioned. Besides, assembling the conventional hanging device is inconvenient and complicated.
Alternatively, a hanging hole is defined at the back of the painting or the LCD screen, and a hook configured on the wall is mated with the hanging hole, so that the hook is engaged with the hanging hole. However, a user has to make a precise measurement for configuring the hook on the wall before hanging the object to the wall. Otherwise, if the hook is improperly configured on the wall, the object would be tilted. A conventional adjustable hanger is provided, however the adjustment of the hook may be performed in a single direction. Accordingly, the conventional adjustable hanger is insufficient for hanging objects properly.
SUMMARY
To address this, the instant disclosure provides a wall hanger comprising a fastening member, a linking member, and a sleeving member. The fastening member is approximately formed as plate shaped, and a first connecting portion is at one side of the fastening member. The linking member is approximately formed as disk shaped and comprises a top wall, a lateral wall, and a bottom wall. The top wall comprises a second connecting portion at the surface thereof to connect with the first connecting portion. The lateral wall is extending vertically toward a first direction distant from one side of the top wall, and the lateral wall has a plurality of first teeth. The bottom wall is extending toward the first direction from the end of the lateral wall, and the bottom wall is parallel to the top wall. The sleeving member comprises a base member, a supporting wall, and an abutting wall. The supporting wall is standing on the base member. The abutting wall is extending from an end portion of the supporting wall and parallel to the base member. A groove is defined by the base member, the supporting wall, and the abutting wall. The top surface of the abutting wall has a plurality of second teeth. The sleeving member is fitted over the bottom wall of the linking member via the groove, so that the second teeth are engaged with the first teeth.
Due to the off-centre configuration of the connecting portions, the wall hanger allows an object hanged thereon to be adjusted vertically and horizontally. Therefore, when two wall hangers are applied to hang on an object, the orientation of the object can be adjusted by adjusting the two wall hangers.
Detailed description of the characteristics and the advantages of the disclosure is shown in the following embodiments, the technical content and the implementation of the disclosure should be readily apparent to any person skilled in the art from the detailed description, and the purposes and the advantages of the disclosure should be readily understood by any person skilled in the art with reference to content, claims and drawings in the disclosure.
