The instant disclosure relates to a wall fastener; in particular, to a wall fastener for a wireless transmission module.
2. Description of Related Art
Because of the development of network associated hardware, its wide use has been rooted in our daily life. A single device for network connection cannot satisfy the ever increasing demand for information from the Internet. The price of associated hardware is decreasing and it has become common for a single user to have more than one device being connected to a network. The trend of heavy signal trafficking is inevitable. The associated hardware for establishing a smaller network domain is available in the market. Wireless transmission is more favorable compared to the other transmission methods and it can be distributed to multiple devices simultaneously.
The conventional wireless transmission module or related hardware is secured on the wall by a fixed rack. This arrangement avoids cumbersome routing and saves space. Also, the signal transmission maintains its stable quality in the distribution.
However, the conventional rack is metallic and locked to the wall. The wireless transmission module is mounted on the rack and typically screws are used to enhance the engagement. For easier disengagement, press fit system may be adapted. In the case of screw fastening, the wireless transmission module cannot be easily removed whereas the press fit system may leave the wireless transmission module being snatched or accidentally taken away by a child.
The instant disclosure provides a wall fastener for a wireless transmission module which is easy to assemble and not easy to disengage. The wall fastener provides secure engagement and spares the wireless transmission module from undesired removal.
The wall fastener for a wireless transmission module includes a supporting frame and a case. The supporting frame has a front face, a rear face, a first engagement portion and a slot. The case has a rear plate which has an outer face, an inner face, a second engagement portion and a stopper. The stopper partially projects out of the outer face. The first and second engagement portions mate and the stopper is received by the slot.
The wall fastener of the instant disclosure uses the first and second engagement portions for mating and the stopper is received by the slot. Through the two different locking systems, the wireless transmission module can be attached to the supporting frame without using additional fasteners. A simple, conventional tool is required to disengage the wall fastener. Therefore the wireless transmission module can not be snatched directly or taken away by a child. The re-assembly is not a problem either.
In order to further understand the instant disclosure, the following embodiments are provided along with illustrations to facilitate the appreciation of the instant disclosure; however, the appended drawings are merely provided for reference and illustration, without any intention to be used for limiting the scope of the instant disclosure.
The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the instant disclosure. Other objectives and advantages related to the instant disclosure will be illustrated in the subsequent descriptions and appended drawings.
Referring to
The material and configuration of the supporting frame 1 are not limited to the instant embodiment. For example, the supporting frame 1 can be configured to be square, round, oval, polygonal and other geometric configuration. In the instant embodiment, the supporting frame 1 is metallic and shaped to be a rectangle for accommodating the case 2. The supporting frame 1 has a front face 11 and a back face 12 opposite the front face 11.
The supporting frame 1 has a first engagement portion 13 and a slot 14. The quantity of the first engagement portion 13 is at least one and it can be two, three, four or above. The quantity and the location of the first engagement portion 13 are not limited by the instant embodiment. In the instant embodiment, four first engagement portions 13 are disposed at the four corners of the supporting frame 1.
The instant embodiment is not intended to limit the configuration of the first engagement portion 13 to that as illustrated and described herein. In the instant embodiment, the first engagement portion 13 resembles a hook A. The first engagement portion 13 is a plate projecting from the back face 12. The first engagement portion 13 (hook A) may have an arm 131 and a finger 132. The arm 131 connects to the supporting frame 1 at one end and horizontally extends (along the X axis in
The quantity of the slot 14 is at least one and it can be two or more. In the instant embodiment, the supporting frame 1 has two slots 14. The slots 14 are formed at the two upper corners of the supporting frame 1 whereas the instant disclosure is not limited to these locations. The slots 14 are configured to be square and going through the front and back faces 11, 12. The slot 14 has a lip 141. The supporting frame 1 is also formed with a plurality of holes 15 for securing the supporting frame 1 onto the wall.
The case 2 of the wireless transmission module has a front case 21 and a rear plate 22. The front case 21 and the rear plate 22 collectively form the hollow case 2. The case 2 receives a signal transmission module 3. The rear plate 22 has an outer face 221 and an inner face 222. The rear plate 22 has a second engagement portion 223 and a stopper 224. The number of the second engagement portion 223 is at least one and it can be two, three, four or above. In the instant embodiment, each of the first engagement portions 13 corresponds to one of the second engagement portions 223 and therefore there are four second engagement portions 223. In the instant embodiment, the second engagement portion 223 resembles a slit B. The slit B is a vertical slit going along the Z axis as shown in
The stopper 224 can only fit into the supporting frame through a single direction. During disengagement, tools are required to conduct the detachment. The quantity of the stopper 224 is at least one and it can be two, three, four or above. In the instant embodiment, the case 2 has two stoppers 224 corresponding to the slots 14. That is to say, the stoppers 224 are disposed at the two upper corners of the rear plate 22. In the instant embodiment, the stopper 224 has an flange 2241. One end of the flange 2241 connects to the rear plate 22 and the flange 2241 slantingly poses therefrom serving as a guiding slope. The other end of the flange 2241 may be formed with a protruding portion 2242 which further connects to a pushing portion 2243. The flange 2241 and the protruding portion 2242 project out from the outer face 221. In other words, the stopper 224 is configured to be partially protruded on the outer face 221. The periphery of the case 2 is formed with recesses 211 for receiving the stoppers 224. The recess 211 allows access to the pushing portion 2243 of the stopper 224 such that a tool can press against the pushing portion 2243. The recess 211 may be formed on the front case 21 alone or crossing between the front and the rear plate 22 (not labeled). The pushing portion 2243 of the stopper 224 is accessible from the recess 211 of the front case 21 whose dimension is sufficient for inserting a tool. If the pushing portion 2243 of the stopper 224 is not entirely accessible from the recess 211 of the front case 21, the recess 211 may expand to the rear plate 22 for an easier access to the pushing portion 2243.
Referring to
In another embodiment of the instant disclosure, the slots 14 may not cut through the front face 11. That is to say, the slots 14 form as depression on the rear face 12 and they still serve the same purpose as receiving the stoppers 224.
The case 2 can be removed from the supporting frame 1 and the detachment steps are described below. Firstly, a tool (for example, a screw driver) is inserted to the recess 211 of the case 2. The tool abuts the pushing portion 2243 and the stopper 224 is pushed inwardly toward the case 2. As a result, the stopper 224 is disengaged from the slot 14. When the tool is inserted, the case 2 should be pushed upward along the Z axis such that the first and second engagement portions 13, 223 are parted. The wireless transmission module is then free to be taken off.
In addition, the case 2 may have only one stopper 224 disposed at the middle portion thereof yet the instant disclosure is not limited thereto. The single corresponding slot 14 is formed at the middle portion of the supporting frame 1. In this regard, the disengagement of the case 2 can be done more easily by one hand. Specifically, the tool is inserted to the recess 211 and abuts the pushing portion 2243. Then the stopper 224 is pushed inwardly toward the case 2. As a result, the stopper 224 is disengaged from the slot 14. When the tool is inserted, the case 2 should be pushed upward along the Z axis such that the first and second engagement portions 13, 223 are parted. The case 2 is then free to be taken off.
Referring to
The wall fastener of the instant disclosure uses the first and second engagement portions for mating and the stopper is received by the slot. Through the two different locking systems, the wireless transmission module can be attached to the supporting frame without using additional fasteners.
The assembly and engagement of the instant disclosure is quick and easy. Without using additional tools, the wall fastener can be assembled yet it prevents accidental removal. A simple, conventional tool can disengage the wall fastener. Therefore the wireless transmission module can not be snatched directly or taken away by a child. The re-assembly is not a problem either.
