Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanging device that is attached to a wall board, particularly a plaster board, for suspending various items, and relates to a hanging device that is attached to a wall board, particularly a plaster board, to hang various items, and relates to a hanging device that is attached to a wall board, particularly a gypsum board, for hanging various items. A gauge for attaching this device has also been proposed, which has a part to be inserted (insertion part), a fixed part that sticks to the back side of the wall board, and a suspended part that remains on the front side of the wall board.

[Conventional technology]

There have been actually two types of anchoring devices of the type mentioned heretofore. The first type is the clap type (folding type) or the kip type (tilting type).
For wall plugs, the insertion part consists of a threaded screw rod with one or two screws at one end.
Two pivotable arms are included as fixed parts.

The rotary joint consists of a cylindrical body with tapped threads that extends across the screw rod. First turn this arm to a position parallel to the screw rod, then pass it through a large hole drilled perpendicularly in the wall plate, and use a spring or gravity to rotate it to a position almost perpendicular to the screw rod, and therefore parallel to the wall, on the back side of the wall plate. Turn until it is. The outer end of the wall plate of the screw rod is engaged with a suspension part having a hook or ring shape or a corresponding opening, and a stopper or at least one nut,
Sometimes one or more washers are provided so that turning the screw rod and/or nut will crimp the mooring device to the wall.

The second anchorage of conventional anchorages is usually of the so-called hollow-leg anchor actuation. This anchor consists of a cylindrical head with an opening in the center and one terminal part, which are assembled by one or several bridges, and the head is inserted into the insertion part. The terminal part with the bridge corresponds to the fixed part. The hole in the head is the screw thread.

The diameter of the opening at the end should be large enough to allow the threaded hook to pass through, and the diameter of the opening at the end should be large enough to allow the screw to be tightened. Insert the anchor into the corresponding opening in the wall.

The part of the head that remains inside the wall is the hand that stops it from rotating inside the wall□
It becomes a step. When you separate the length of the screw in the anchor and turn the screw with a stopper, the terminal part on the back side of the wall plate will move to the wall plate as the bridge will knick (bend) and the legs will open. Strong tension is applied.

[Problems that the invention attempts to solve] Although both types of anchoring devices are in practical use.

In practice, it has the following drawbacks.

First of all, wall plugs called clap type or kip type,
Material and manufacturing costs are extremely high.

That is, a large number of mechanical parts are required by machining processes such as punching, bending, drilling, turning, etc., resulting in a high cost for each part. Other shortcomings are as follows. In other words, because the diameter of the hole drilled in the wall needs to be large, the screw bolt that passes through the hole cannot be inserted neatly, and it has no effect on the purpose of receiving a load.

Second, splayed anchors are similarly expensive to manufacture.

This is because it has a head part and a terminal part, as well as a bridge that connects these parts, making it relatively complex in shape. Set the specified knick positions near the head, end, and center of the bridge.

Depending on the situation, if high stress is applied, it will break and reduce the load capacity of the anchoring device. In addition to this, the load distribution occurs over a relatively narrow area, so that at high loads there is a risk that the wall will collapse.

Furthermore, common drawbacks of both types of suspension devices are as follows. In other words, the so-called clap-type or split-leg structure requires a deep space behind the wall, but this is not always possible.

Other shortcomings specific to both types of devices are as follows. In other words, they cannot be removed from the wall without causing further damage to the wall, and as a result, these suspension devices are either disposable or cause significant damage to the wall.

Therefore, it avoids the above-mentioned drawbacks, is easy to work with, is inexpensive, can withstand loads, is easy to assemble, is reliable, can be positioned accurately, requires less depth for installation, and can be removed without further damage to the wall. The problem is to provide a suspension device of the type mentioned at the outset, which can be reused.

Means for Solving the Problems According to the invention, the first V-leg is made from a metal or plastic band bent in an IVe shape across the longitudinal axis, so that the first V-leg is placed in front of the wall. This problem is solved by a mooring device of the type mentioned at the outset, in which the second V-leg remains in the suspension part and the second V-leg becomes the insertion part and the fixed part alongside it.

[Operation and effects of the invention]

As a result, the material and manufacturing costs for making the anchoring device are actually reduced. This is because there is no need to manufacture complicated parts such as joints and screws.

When assembled, the first V-leg, or suspension section, rests flat on the wall with the downward facing end of the leg, and the second leg,
In other words, the insertion part and the fixed part fit into a perfect slit cut in the wall at an acute angle and diagonally downward. Therefore, the force generated from the load applied to the device is smaller than the V-Length material between the legs. But it will be accepted. When the wooden figure mounting device is no longer needed in its traditional position, it can be very easily removed from the slit and installed in a new location.
In that case, the only damage left in the wall is a narrow slit, which can be refilled invisibly.

(Embodiment) ``''1 A preferred configuration of the present invention is as follows. That is, the second V
- Draw an obtuse angle between the insertion part and the fixed part that make up the leg (V-
divided by a second knic running parallel to the knic;
In this case, the fixing part and the first V-leg extend parallel to each other with a distance of approximately one normal plate thickness. If the suspension device is structured to match a certain plate thickness in this way, the risk of the wall board between the V-legs being chipped or detached by simply inserting it with a slight force will be further reduced. .

This is because the contact surface of the device with the wall plate can be made large regardless of the thickness of the wall plate material. Additionally, the depth of space required behind the wall is minimized. This is because it is sufficient that this depth is slightly larger than the thickness of the legs of the device.

It is also advisable to provide openings, preferably elongated holes, in the same row in both V-legs for screw fixing to increase stability. In particular, the width of the opening in the second leg, that is, the fixed part, is narrower than the width of the opening in the first leg, that is, the suspended part, so that the screw passed through the first leg and the wall is connected to the second leg. It is preferable that the collar rests on or fits into the opening of the collar. As a result, a strong tension is created between the anchoring device and the wall plate, and a secure and immovable positioning is achieved. Threading can also take place, for example, with a self-tapping screw and an unthreaded opening, or with a screw thread and a tapped hole in the fixing part.

In order to guarantee the widest possible fluctuations in the anchorage performance of the device, the first V@, i.e. the suspension part lying flat on the wall, can be fitted with attachments, e.g. hooks, loops, etc. ξ is also preferable. This device is used in conjunction with the previously described screw fixation method. However, in that case, the shape of the suspended portion can also be changed as follows. That is, independently of screwing, it is possible to attach one or more attachments by screwing, gluing, hooking, crimping, or other methods.

Another implementation with particularly reasonable manufacturing possibilities is to make the first V-leg integral with attachments such as hooks, rings, etc.

In that case, there is no need to process a large number of parts, so
Inventory management and installation become easier. Moreover, the one-piece structure greatly contributes to the stability of the device.

To install this suspension device, it is necessary to make a slit in the wall that fits snugly at an angle determined by the V-knick of the device, so it is best to use a flat guide gauge for this purpose. In other words, in order to make a slit in the wallboard, especially plasterboard, necessary for inserting the second V-leg, a flat chisel guide that reaches the bottom of the base plate at an angle half that of the gauge Ccv-knick is attached. It is preferable to attach a base plate. This gauge is effective in setting the running angle of the slit in the wall necessary to hold the suspension in the correct position; without this gauge, the direction will be inaccurate and Differences may occur between slits. To prevent the gauge from sliding down, it is recommended to add a material to the back of the base plate to increase friction or change the shape of the surface.

In order to keep this suspension device in the correct position, it is necessary to accurately determine the position of the slit in the wall. It is therefore preferable that the gauge, or at least its base plate, be made of a transparent material so that the markings on the wall are clearly visible even after the gauge has been installed, allowing accurate placement of the gauge.
