Wall-mounted aiding mechanism and wall-mounted device

An exemplary embodiment of a wall-mounted aiding mechanism for firmly attaching an object to a vertical wall and which is proofed against external impacts includes a casing, a sliding plate and an adjusting screw. The casing defines a first receiving space to receive the sliding block which performs a collaring or shearing action on a fastener such as a screw. The adjusting screw passes into the receiving space of the casing. The adjusting screw engages with the sliding block to lift the sliding block to a topmost position of the receiving space or disengages with sliding block to let the sliding block drop onto the neck of the fastener and hold it secure.

BACKGROUND

1. Technical Field

The present disclosure generally relates to a wall-mounted aiding mechanism for mounting a device on a wall and a wall-mounted device using the wall-mounted aiding mechanism.

2. Description of Related Art

Wall-mounted devices can be used on a wall. A typical wall-mounted device includes a main body and a plurality of mounting screws for mounting the main body on the wall. The main body may be an air conditioner, an LCD, a telephone, a clock, for example. A rear of the main body defines a plurality of mounting holes. Each mounting hole includes a collar hole and a guiding hole connecting each other. Each mounting screw includes a screw head and a fixing pole extending from the screw head. A distal end of the fixing pole is fixed in the wall. To fix the main body of the wall-mounted device on the wall, the screw heads and the fixing poles pass through the guiding holes, and the main body is pushed to move relative to the mounting screws to let the fixing poles of the mounting screws slide from the large guiding holes to the collar holes, and the fixing poles are thus blocked in the collar holes. The main body is supported on the mounting screws, and the main body is mounted on the wall.

However, when the main body of the wall-mounted device is impacted by an external object or force, the fixing poles are liable to slide from the collar holes to the guiding holes, and release the mounting screws from the mounting holes of the main body, such that the wall-mounted device tilts or falls from the wall.

What is needed, therefore, is a means which can overcome the described limitations.

DETAILED DESCRIPTION

Reference will be made to the drawings to describe various embodiments.

Referring toFIG. 1, in one embodiment, a wall-mounted device1includes a main body11, a plurality of mounting screws10, and a plurality of wall-mounted aiding mechanisms12. The main body11can be mounted on a wall via cooperation of the mounting screws10and the wall-mounted aiding mechanisms12.

The main body11may be any body/structure which can be mounted on a wall, for example the main body11can be an air conditioner, an LCD, a telephone, a clock, for example. The main body11includes a plurality of first mounting holes112. Each first mounting hole112includes a first guiding hole116and a first collaring hole113connecting with each other. The first guiding hole116has a greater overall diameter than a diameter of the first collaring hole113.

InFIG. 2, each mounting screw10includes a screw head105and a fixing pole102connecting with the screw head105. The screw head105has a greater diameter than a diameter of the fixing pole102, and the fixing pole102extends from a first stopper surface108of the screw head105. The mounting screws10can slide in the first mounting holes112. The screw head105of the mounting screw can pass through the first guiding hole116and the fixing pole102can then be blocked in the first collaring hole113.

Each wall-mounted aiding mechanism12includes a casing13, a sliding block15, an adjusting screw16, a washer17, and an elastic member18.

The casing13includes a base body130, two fixing plates136, and a protruding plate137. The base body130includes a bottom plate131and a plurality of sidewalls132, and the bottom plate131and the sidewalls132cooperate to form a receiving space134to receive the sliding block15. The bottom plate131defines a sliding hole139. In this embodiment, the casing13includes four sidewalls132. The fixing plates136are arranged opposite to each other and extend from edges of two opposite sidewalls132. One of the two opposite sidewalls132defines a through hole138. The protruding plate137is adjacent and parallel to the sidewall132having the through hole138, and the protruding plate137defines a through hole138coaxial with the through hole138of the sidewall132. One of the two fixing plates136perpendicularly interconnects the protruding plate137and the sidewall132having the through hole138. The through holes138define a common axis135.

The sliding block15includes a first end150and a second end151opposite to the first end150, and the first end150is adjacent to the sidewall132having the through hole138. The sliding block15defines a threaded hole159at the first end150and a second mounting hole152at the second end151. The threaded hole159is coaxial with the through holes138. The second mounting hole152includes a second collaring hole153and a second guiding hole156connecting with each other. The screw head105of the mounting screw10can pass through the second guiding hole156and the fixing pole102can be blocked in the second collaring hole153by means of what is substantially a shearing function by the sliding block15. The sliding block15is movably received in the receiving space134of the casing13, and can move up and down along a direction parallel to the common axis135of the through holes138.

The adjusting screw16includes a head portion165and an adjusting pole162connecting with the head portion165. The head portion165has a greater diameter than that of the adjusting pole162, and the adjusting pole162extends from a second stopper surface168of the head portion165. The adjusting pole162has a screw thread167at a distal end of the adjusting pole162. The adjusting pole162defines a fixing groove169around a circumference of the adjusting pole162. The washer17sleeves on the adjusting pole162and is received in the fixing groove169. The elastic member18sleeves on the adjusting pole162, and is located between the distal end of the adjusting pole162and the washer17.

Referring also toFIG. 1andFIG. 3, in assembly of each wall-mounted aiding mechanism12and the main body11, the fixing plates136of the casing13are fixed to the rear of the main body11via screws133, with the sliding hole139corresponding to a first mounting hole112of the rear of the main body11. The sliding block15is movably received in receiving space134of the casing13. The adjusting pole162passes through the through holes138. The washer17is fixed in fixing groove169of the adjusting pole162, and is located between the protruding plate137and the sidewall132having the through hole138, to prevent the adjusting pole162being detached from the casing13. The elastic member18sleeves on the adjusting pole162and is sandwiched between the washer17and the sidewall132having the through hole138. The elastic member17exerts resilient force when the adjusting pole353moves up and down along the direction parallel to the common axis135.

The sliding block15can be in a first state (seeFIGS. 3-4) or a second state (seeFIGS. 5-6). When the sliding block15is in the first state, the sliding block15is disengaged with the adjusting pole162, and the sliding block15moves down along the direction parallel to the common axis135due to gravity. When the sliding block15is in the second state, the screw thread167of the adjusting screw16is rotated into the threaded hole159of the sliding block15, the sliding block15is thus engaged with the adjusting pole162, and the sliding block15is thus lifted to a top position of the receiving space134, such that the second collaring hole153of the second mounting hole152aligns with the first collaring hole113of the first mounting hole112, and the second guiding hole156of the second mounting hole152aligns with the first guiding hole116of the first mounting hole112.

Referring also toFIG. 7, to fix the main body11on the wall, the wall-mounted aiding mechanisms12are fixed to the rear of the main body11, the mounting screws10are fixed in the wall, the sliding blocks15are lifted up to be in the second state, the screw heads105and the fixing poles102of the mounting screws10are passed through the sliding holes139, the second guiding holes156and the first guiding holes116. Then the main body11is pushed to move relative to the mounting screws10to let the fixing poles102to slide from the guiding holes156,116into the collaring holes153,113. Thus, the main body11is supported on the mounting screws10, and the main body11is mounted on the wall. After that, the adjusting screws16are turned to change the sliding blocks15to the first state from the second state. Such that, in the first state, the adjusting screws16disengage with the sliding blocks15to let the sliding blocks15drop onto the fixing poles102of the mounting screws10and hold it secure.

With the above-described configuration, when the main body11is impacted by an external force, and the main body11is pushed to move relative to the mounting screws10, because the sliding blocks15are disengaged from the adjusting poles162after the main body11is mounted on the wall, and the sliding blocks15are movable in the receiving spaces134, the sliding blocks are still supported on the mounting screws10, and the fixing poles102are still held captive in the second collaring holes156of the sliding block15when the main body11is pushed to move relative to the mounting screws10. The first stopper surfaces108of the mounting screws10prevent the mounting screws from detaching from the wall-mounted aiding mechanisms12(seeFIGS. 8-9). Therefore, the main body11is always firmly mounted on the wall.
