Abstract

The present invention relates to a fixing bracket for fixing the opening door of an open house to the wall to be kept open without closing.

In the summer high-rise apartments open the windows to the outside to let the wind in, if the strong wind blows often the opening door of the room closes suddenly.

When the door is closed, it is annoying to open it again, the family members are surprised to hear loud noises, and the noises on the upper and lower floors make them feel sorry for their neighbors.

In many cases, heavy doors keep the doors closed so that they can't be closed, but the process of removing them is cumbersome, preventing entrance and being awkward.

In order to solve the above problems, the swing door fixing bracket of the present invention opens the swing door until it touches the wall, and the magnet attached to the wall pulls the magnetic plate or the iron plate attached to the door to fix the swing door to the wall.

The swing door fixing bracket of the present invention has a buffer container made of elastic and elastic material such as rubber, which is characterized by reducing the shock and the noise applied to the wall when the door is opened and pushed toward the wall.

In addition, the angle of the magnet is changed according to the angle of the magnet plate attached to the swing door, so that the magnet and the magnet plate are in perfect contact.When the pull door is pulled to close, the support point which prevents the magnet connected to the wall from being dragged is always at the centerline of the magnet. It is designed so that the magnet and the magnetic plate are not sequentially separated from one direction but the entire adhesive surface is separated at one time so that the resistance to separation is maximized.

Description

Swinging Door Lock {door-stop}

The present invention relates to a fixing bracket for fixing to a wall so that the doors of an open house remain open instead of closing, using magnets that pull each other. A magnet is attached to a wall, and a door or a door is attached to a magnet or a magnet. By attaching a magnetic plate made of adhesive material to open the door and sticking it to the wall, the magnet and the magnetic plate are attached and the door is fixed to the wall with the door open so that the wind can pass through.

Swing door fasteners, which use magnets to prevent the doors of furniture from being opened closed, are still widely used.

However, the magnetic swing door fixing bracket used for furniture cannot be used to open and lock the swing door used as the door of the room.

When the furniture closes the door, the door swings against the floor plate, the top plate or the wall plate of the furniture, so that the magnet is not directly impacted.

However, if you use the conventional fasteners used for furniture to fix the swing door used as the entrance door of the room, the magnet must bear the impact of the swing door opening when the swing door is pushed against the wall when the sliding door is pushed against the wall. There is a problem that the fixing bracket is easy to break.

Conventional swing door fasteners used for furniture are made by screwing them into the wall or top of the furniture perpendicular to the adhesive side of the magnet, but fastening used to secure the wall with the swing door open. Since the metal fittings must be attached to a wall parallel to the surface that is the adhesive side of the magnet, magnetic fasteners used in conventional furniture cannot be used.

When the door is opened and pushed toward the wall, the shock generated by the door is not transmitted to the magnet, and the impact and noise caused by the collision between the door and the door is reduced, and the wall that is parallel to the adhesive surface of the magnet It is an object of the present invention to make a sliding door lock.

The swing door fixing bracket of the present invention is composed of an inner cylinder 20, a through shaft 30, a magnet 40, a buffer cylinder 50, and a magnetic plate 60, as shown in FIGS. 3 to 10.

The inner cylinder 20 has a rectangular cylindrical shape in which the left side is blocked and the right side is open, and on the left side of the block, there is a screw groove 22 for screwing a screw to fix the inner cylinder to a wall, and an inner tube for fitting the upper and lower portions of the inner shaft 30 upright. The groove 21 is formed.

The through shaft 30 inserted into the inner through groove 21, the outer through groove 51 and the magnet groove 41 to couple the inner cylinder 20 to the buffer cylinder 50 and the magnet 40 has a circular rod shape. It is made to have a smaller diameter than the inner through groove 21 so that it can be easily inserted and removed, the upper portion of the circular plate shape is larger than the outer through groove 51 so that the through shaft 30 does not flow down from the inner cylinder Hair is formed.

The magnet 40 is coupled to the inner cylinder 20 by the through shaft 30 and is made of a magnetic material. The magnet door 60 attached to the swing door and the swing door opened and glued together by the pulling force are fixed to the wall. Make it as possible.

The magnet 40 is a cube-like cube and a rectangular magnet groove 41 penetrating from the top to the bottom is formed, and a center protrusion 42 having a semi-circular cross section protruding horizontally at the middle height of the left side of the magnet groove is formed. The center protrusion 42 makes the position where the through shaft 30 and the magnet 40 contact is at the center of the magnet.

The square formed to the left and right of the magnet groove 41 and the width in the front and rear direction is slightly larger than the diameter of the through shaft 30 so that the through shaft 30 can be easily entered, and the length in the left and right directions is larger than the diameter of the through shaft 30. It is much longer so that the magnet can move from side to side even when the through shaft is engaged.

On the bottom of the magnet 40, two narrow pedestals 43 protruding downward in front and rear of the magnet groove 41 are formed long in the front-rear direction. A space is created between the 20, so that the left and right sides of the magnet are easily tilted up and down like a seesaw in a children's playground.

Buffer 50 is a rectangular tube shape of the left and right open and is made of a size that can be inserted into the inner cylinder 20, the material is made of elastic and elastic material such as rubber or rubber in Figure 2 As shown in the figure, when the sliding door is opened and pushed toward the wall, the magnetic plate attached to the door serves to reduce the impact and noise caused by the collision with the magnet, and the outer through groove 51 fitting the through shaft 30 is upper and lower. It is formed at the bottom.

The magnet plate 60 is in the form of a square plate and is made of a material that adheres well to the magnet and is attached to the door 11 with a screw 16 as shown in FIG.

The magnetic plate 60 has a screw groove 61 to which the nail is attached when attaching the magnetic plate to the swing door, and opens and closes the swing door to which the magnet plate is attached to the wall as shown in FIG. 2, and the magnet 40 is attached to the wall. It is bonded to and the swing door is fixed to the wall as shown in FIG.

The magnet 40 and the magnet plate 60 may both be made of a magnet, and either one may be made of a material such as iron, which is not a magnet but has a property of being attracted to the magnet.

Pull out the through shaft 30 from the inner cylinder 20 and the buffer cylinder 50, and fix the inner cylinder to the wall with a screw while the magnet 40 is lifted out of the inner cylinder 20. Then, the through shaft and the magnet are combined with the inner cylinder. And the magnetic plate 60 is attached to the swing door with a screw, the installation is completed as shown in FIG.

As shown in FIG. 2, when the opening door with the magnetic plate 60 attached to the magnet 40 coupled to the inner cylinder 20 fixed to the wall is opened, the positional relationship between the magnetic plate and the magnet is as shown in FIG. In this state, when the door is closer to the wall to collide with the magnetic plate and the buffer tube, as shown in FIG. 12, the magnet 40 is attracted by the magnetic force to be bonded to the magnetic plate, and the door is shown in FIG. It is fixed to the wall and does not close even when the wind blows. The shock absorber 50 is made of a soft and elastic material to mitigate the noise and shock generated when it collides with the magnetic plate, and as shown in FIG. Even if the magnetic plate collides with the magnetic plate protruding to the right, the magnet is pushed into the buffer cylinder, so that the direct shock is handled by the buffer cylinder.

As shown in FIG. 1, when a pulling force is applied in a direction in which the door is closed while the door is fixed to the wall, the magnet is pulled to the right as shown in FIG. 13, but the center protrusion 42 has a through shaft ( 30) can no longer come out and stop.

When a user pulls the swing door fixed to the wall with strong force, the magnet plate and the magnet are separated as shown in Fig. 14, and the swing door can be closed. When the swing door to which the magnetic plate 60 is attached is fixed to the wall, the inner cylinder If the surface of the wall on which the 20 and the magnet 40 are attached and the surface of the swing door form a parallel plane, as shown in Fig. 13, the surface of the magnet and the surface of the magnetic plate form a parallel plane and are in contact with each other to maximize the adhesive force. And, as shown in Fig. 2, the distance between the inner cylinder 20, the wall to which the magnet 40 is attached, and the hinge to attach the swing door to the door frame is farther than the length of the state in which the buffer cylinder and the magnet plate are coupled to each other. In the case where the surface of the opening door and the surface of the opening door are not parallel, as shown in FIG. 16, the magnet is rotated about the through shaft 30 so that the surface of the magnet and the surface of the magnetic plate are parallel to each other. Evenly contacted for maximum adhesion.

When the distance between the surface of the wall and the upper part of the door is small and the distance between the surface of the wall and the lower part of the door is large, the contact state between the magnet attached to the wall and the magnet plate attached to the door is as shown in FIG. The magnet is inclined to the right with the contact point of the center projection 42 and the through shaft as the center of rotation, so that the surface of the magnet 40 and the magnet plate 60 are evenly contacted as a whole to maximize the adhesive force.

As described above, when the swing door approaches the wall in a state where the surface of the wall and the surface of the swing door do not form parallel planes, the left and right lengths of the magnet groove 41 in the horizontal cross section are passed through the through shaft 30. If the diameter is equal to) and there is no free space, the magnet cannot be tilted from side to side, so that only a part of the magnet and the magnetic plate come into contact with each other, thereby weakening the adhesive force.

As shown in FIG. 18, even if the left and right lengths of the magnet groove 41 are sufficiently larger than the through shaft 30, the magnet 40 is easily inclined from side to side, and the magnet and the magnetic plate 60 are completely in contact with each other over the entire area. If there is no center projection 42, when the swing door fixed to the wall is pulled to release the adhesive, the center part of the magnet and the through shaft 30 do not come into contact with each other, and the upper part of the magnet comes into contact with the upper part of the magnet. This action separates the magnet and the magnetic plate sequentially from the top like when splitting a tree with an ax, and the resistance to separation is weakened, so that the opening door cannot be tolerated and easily closed when the wind blows.

In the present invention, the inner cylinder 20 and the buffer cylinder 50 are made separately, but there is a material that is excellent in elasticity and elasticity and is not easily torn, even though the through shaft 30 is pushed to the right by the magnet 40. If it does not tear, it is possible to make the inner cylinder and the buffer cylinder integral.

In addition, the inner cylinder, the buffer cylinder, and the magnet can be made into a circle rather than a square to perform the same function.

The swing door fixing bracket according to the present invention is a bracket that the magnet does not close by opening the swing door to the wall by using the pulling force of each other.It pulls out the through shaft, separates the magnet from the inner cylinder, and fixes the inner cylinder to the wall. Because it can be embedded in the screw, the appearance is beautiful without exposing the screw to the outside.

In addition, the shock absorber is made of elastic material, which has the advantage of reducing the impact and noise generated when the swing door is hit.The magnet is pushed into the shock absorber when the swing door hits the fixing bracket, and the magnet is impacted. This prevents the magnet, the through shaft and the inner cylinder from being damaged.

In addition, even if the center protrusion that prevents the magnet from being pulled when the door is pulled and closed is pulled in a state in which the magnet is inclined to the left or right in the center line of the magnet, separation of the magnet and the magnetic plate does not occur sequentially from the top or the bottom. This makes it possible to separate at the same time to maximize the resistance to prevent the door from closing.

Since the bottom of the magnet has a pedestal, the magnet is easily inclined from side to side according to the angle of the magnet plate, so that the magnet and the magnet plate are evenly contacted, thereby maximizing the adhesive force.
