DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Embodiment 1-1] The present invention relates to a door stopper, which includes a door 100 that pivots, and a support 200 mounted on the lower surface of the door and vertically movable in the vertical direction.

The present invention relates to a door stopper. The door stopper is for opening the door, and is installed on the lower surface of the door and is supported on the ground. The present invention relates to a technique for removing the supporting force of a door and a floor by moving a supporting portion in an upper direction in case of door closing. In the conventional door stopper, the support portion is rotated. The conventional door stopper has to be moved a small amount toward the rear side when the door is rotated. This is because the lateral support force of the door stopper and the ground must be released. However, since the door stopper of the present invention is moved upward, it has an advantage that the door can be closed without moving the door backward.

[Embodiment 2-1] A door stopper of the present invention includes, in Embodiment 1-1, a housing 300 in which one side of the support portion is housed and one side is coupled to the door.

In order to move the support portion upward, the support portion and the housing for fixing the support portion must be separated from each other. That is, the housing is fixed to the door, and the supporting part is inserted into the housing and moved in the vertical direction.

[Embodiment 2-2] The door stopper of the present invention includes, in Embodiment 2-1, a vertical movement guide 310 formed between the housing and the support.

[Embodiment 2-4] A door stopper according to the present invention includes, in Embodiment 2-3, the friction plate made of Teflon.

[Embodiment 2-5] In the door stopper of the present invention, in Embodiment 2-3, the friction plate is formed on the housing and / or the support.

For stable movement of the support and the housing, a vertical movement guide is formed between the abutment surfaces of the support and the housing. The vertical movement guide is formed as a projection and a groove. A projection is formed in the housing, and a groove is formed in the supporting portion. The grooves and the protrusions may be disposed opposite to each other. A friction plate is formed between the vertical movement guides. The support and the housing are frequently rubbed, which causes wear of the contact surface. The friction plate may be mounted separately on the housing or the support, or on both the housing and the support. Since the friction plate is made of a Teflon material, the frictional coefficient can be remarkably reduced. It can be replaced with an object that exhibits the same purpose and effect as the Teflon material. The friction material can be coated instead of the friction plate.

[Embodiment 2-6] The door stopper of the present invention includes, in Embodiment 2-1, an insulating plate 330 formed between the housing and the door.

In the event of a fire, the support must be automatically moved to the top. This is to forcefully close the door. Electronic equipment is formed inside the door stopper. The electronic equipment is vulnerable to heat. Therefore, it is impossible to forcibly close the door in case of fire. To prevent this, an insulating plate is mounted between the door stopper and the door. The exterior of a conventional fire door is made of metal. The metal conducts heat rapidly, and the conducted heat can damage the equipment inside the doorstop. In order to block the housing conduction of the heat, an insulating plate is mounted between the housing and the door.

The support portion of the present invention is moved downward by a pedal operation, which will be described later, and the first elastic means inserted therein moves the support portion upward by an elastic restoring force. This is because the first elastic means is located inside the door stopper. The first elastic means can be applied to all elements that are elastically restored. However, it is preferable to use a coil spring. The spring can be deflected by frequent compression action. To prevent this, both ends of the spring fix the spring mounting position by the first projection and the second projection. Further, the first projections and the second projections control the length to be downwardly brought into mutual contact. The first projection and the second projection may be replaced by grooves that receive the outer periphery of the spring.

[Embodiment 4-1] A door stopper according to a second embodiment of the present invention is a door stopper according to the embodiment 2-1, wherein the support part is a rod, a support base 210 having one side in contact with the ground, (Not shown).

The supporting part comprises a moving table and a supporting table. The movable table is accommodated in the housing, and the supporting table is formed to extend from the moving table in one direction. The support is formed in an oblique direction, and the oblique direction is formed in a direction in which the door is closed. The support is in contact with the ground. The moving table is formed in a block shape, and the supporting table is formed in a bar shape. The moving table and the supporting table may be integrally formed or separately manufactured and fixed by screws or the like. The support is adjustable in length by the user. Preferably, the amount of protrusion is adjusted by rotation of the support. Since the length of the support by vibration can vary, fastening means are formed on the support and the movable table for completely fixing the support.

[Embodiment 4-3] The door stopper of the present invention is the door stopper of embodiment 4-2, wherein the supporting elastic body is formed of rubber.

[Embodiment 4-4] The door stopper of the present invention includes the slip prevention groove 212 formed on one surface of the support elastic body and formed in plural in the embodiment 4-2.

A support elastic body is formed between the support and the ground. The supporting elastic body is formed of rubber. A slip prevention groove is formed on the surface contacting with the ground. The rubber exhibits a high coefficient of friction by forming stool. Therefore, it stably adheres to the ground. The ordinary slip prevention grooves are for preventing the contact between the support elastic body and the ground from being separated by minute particles (gravel or the like) existing on the ground.

[Embodiment 4-5] In the embodiment 4-2, the door stopper of the present invention includes a supporting hinge 213 positioned between the supporting stand and the supporting elastic body.

A support hinge is formed between the support elastomer and the support. The support hinge allows rotation of the support elastic body at an angle. This is to allow stable support under poorly ground flatness.

[Embodiment 5-1] A door stopper of the present invention includes a pedal 500 according to the embodiment 4-1, which is coupled to the support portion and has one side protruded.

[Embodiment 6-1] A door stopper according to a fifth embodiment of the present invention is a door stopper according to the embodiment 5-1, wherein the pedal center part 510 formed at the pedal center part, the operation protrusion 520 protruding from the pedal center part, A first ratchet (540) hinged to the inside of the housing and hinged to the other end of the first ratchet (530) in contact with the operation protrusion; a first ratchet (540) And a second ratchet 550 coupled thereto.

The support portion is inserted into the housing and moved to the upper and lower portions. When the pedal is depressed, the support portion is moved downward. When the pedal is rotated in the upward direction, the support portion is moved upward and moved to the original position. The pedal and the support are hingedly engaged. The hinge forms a pin shape and connects the center of the pedal and the support. The operation of the pedal is not moved downward but only upward. The housing defines a pedal support surface, the pedal support surface contacting the lower portion of the pedal. That is, when the pedal is depressed, the support portion is moved downward. On the other hand, when the pedal is lifted up, the pedal is pivoted by the hinge, and the actuating projection coupled with the pedal center is pivoted. The actuating projection pushes one side of the fixing table to rotate the fixing table. A first ratchet is formed on the fixed base, and the first ratchet is simultaneously rotated by the rotation of the fixed base. Thus, the first ratchet is separated from the second ratchet. The first ratchet coupled to the fixed base engages with the second ratchet, allowing only one direction movement. In order to allow the one-way movement, the first ratchet and the fixed base engage the hinge and apply an elastic force to the torsion spring. The torsion spring may be replaced with a leaf spring or the like. That is, when the pedal is depressed, the support portion moves downward, and the second ratchet fixed to the support portion comes into contact with the first ratchet rotatably coupled to the fixed base, and pushes the first ratchet to enable downward movement.

[Example 7-1] A door stopper of the present invention is a door stopper according to Example 6-1, which includes a first inclined surface 531 formed on one side of the fixed table and made of a partial inclined surface, And a second inclined surface 222 formed at the same angle as the inclined surface.

When the pedal is rotated upward, the operating projection mounted on the pedal rotates the fixed base. The pivoting restraint must be restored to its original position with the support raised. To solve this problem, a first inclined surface is formed on the second fixing table, and a second inclined surface having the same angle as the first inclined surface is formed on the supporting portion. During the upward movement of the second inclined surface, the second inclined surface is in contact with the first inclined surface, and when the two first and second inclined surfaces are in complete contact, the support is no longer moved and the support is moved to its original position. Also, the fixture is fixed at its original position.

[Embodiment 8-1] A door stopper according to the present invention is the door stopper according to the embodiment 5-1, comprising: a fixing table rotating means (600) for rotating the fixing table, wherein the supporting portion is moved downward by the operation of the fixing table rotating means; .

In the event of fire, the fixture must be forcibly rotated without user intervention, in order to close the fire door. External signals must be pivoted. This is accomplished by means of a fixed base turning means. When the fixed table is forcibly rotated by the fixed table rotating means, the spring elastic force moves the supporting portion upward to forcibly close the door.

[Embodiment 8-2] A door stopper according to the eighth embodiment of the present invention is characterized in that the fixing table rotating means comprises: a permanent magnet 610 formed on the other side of the fixing table; And an electromagnet 620 formed on the corresponding surface of the magnet 620.

The fixed arm forced rotation uses a permanent magnet coupled with a fixed arm and an electromagnet formed in the housing. Normally there is no magnetic force. However, when a fire signal is generated, the electromagnet is excited to generate a magnetic force, which forces the fixed table to operate. In another embodiment, a motor is mounted on a fixed base hinge shaft, and the motor can move the fixed base by applying a rotational force by a fire signal.

[Embodiment 8-3] A door stopper according to an eighth embodiment of the present invention includes a power supply unit 710 that is energized with the electromagnet and supplies a current to the power supply unit, A switch 720, and a controller 730 for controlling the switch operation.

[Embodiment 8-4] A door stopper of the present invention includes, in Embodiment 8-3, a sensor 740 for applying an energizing signal to the controller.

[Embodiment 8-5] In Embodiment 8-4, the door stopper of the present invention includes a fire detection sensor 750.

In order to supply current to the electromagnet and motor presented above, the external power supply is supplied to the power supply. Since the power may be cut off in the event of a fire, the capacitor stores a certain amount of external power. That is, the electromagnet and the motor are operated by the electric power of the battery. In another embodiment, a consumable battery is inserted into the housing and is powered by a battery. Power is not continuously supplied to the electromagnet (motor, etc.). Power must be supplied only in case of fire. Specifically, the power of the battery must be supplied to the electromagnet (motor, etc.) only in case of fire. The switch is activated by the fire signal, and the switch operation activates the electromagnet (motor, etc.). Thus, the fire signal activates the switch by the controller. The controller receives the information of the fire sensor signal. The fire sensor receives the signal by the indoor sprinkler operation state, the fire button operation signal, or an external signal. A fire can occur in an unscheduled situation, and if not used for a long period of time, it can lead to an inoperative state in the event of a fire.

To solve this problem, a fire signal button is formed outside the housing. The user periodically activates the fire signal button to check frequently whether the device is operating normally. When the user periodically activates the fire signal button, the controller activates the switch, and the switch actuates the electromagnet and the motor to forcibly rotate the fixed frame.

Attach the charge confirmation lamp to the outside of the housing. The charge confirmation lamp is formed of an LED or the like. When the battery is normally charged, the LED emits a normal signal. However, if it is not normally charged, the LED or the like does not show a signal. This is to allow the user to visually recognize the state of charge.
