Description

Door holder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door holder, and more particularly, to a door holder coupled to a door to fix the door at an arbitrary position.

A door is a necessary component in a building as means for partitioning or establishing communication between the spaces formed in the building. Many door accessories related to the door have been released for convenience of use.

Door accessories can largely be divided into door stoppers, door holders, door stays, and door closers. Among them, the conventional door holder is a horseshoe-shaped door holder, which is rotated by the external force of the user to fix the door. However, since the conventional horseshoe-shaped door holder must exert an external force on the door holder upward from the ground in order to release the door, the user tilts while providing external force to the door holder And has a problem causing a lot of inconvenience.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a door holder in which a user can easily apply an external force to a door holder.

A door holder according to the present invention is a door holder coupled to a door to fix the door at an arbitrary position, the door holder comprising: a housing fixed to the door; A main body portion which is moved on the housing when an external force of the user is applied; A sub body unit which is moved on the housing when an external force of the user is applied; And the main body portion is moved from a moving position to a fixed position when an external force is applied to the main body portion and the door is moved to a predetermined position And when an external force is applied to the sub-main body in a state where the main body is fixed at the fixed position by the intermediate portion, by the positional movement of the intermediate portion by the sub-main body, Position to the moving position.

Wherein the main body portion is not movable when the intermediate portion is in the locked position and is positionally movable when the intermediate portion is in the released position and is fixed at the fixed position when the intermediate portion is positioned at the locked position when the intermediate portion is below the reference temperature, So that the main body is moved from the fixed position to the moving position as the intermediate portion is moved from the locked position to the released position, even if no external force is applied to the sub-body when the temperature is equal to or higher than the reference temperature. Lt; / RTI >

In addition, the mediating portion may include a restricting portion for preventing the main body portion from being moved when the locking portion is in the locked position and allowing the main body portion to be moved when the releasing portion is in the releasing position, and a reaction portion mediated with the restricting portion. And when the limit is higher than the reference temperature, the restriction portion is located at least partially in a space that can not be positioned when the limit portion is lower than the reference temperature, and is moved from the lock position to the release position.

Here, the restriction unit may be configured such that when the external force is applied to the sub body unit, the restriction unit is positioned with respect to the reaction unit, and is moved from the lock position to the release position, If it is above the reference temperature, it can be configured to dissolve.

Preferably, the reaction unit is configured such that the movement of the reaction unit is limited by the housing and the restriction unit so that the restriction unit can be moved with respect to the reaction unit.

In this case, the main body part can not be moved when the intermediate part is in the locked position, and can be moved when the intermediate part is in the unlocked position. , The sub-portion may be configured to provide an external force to the intermediate portion such that a position of the intermediate portion is maintained in the locked position when no external force is applied to the main body portion.

Furthermore, the sub-main body may be moved in a direction orthogonal to a direction in which the main body is moved on the housing when an external force of the user is applied.

The present invention may further comprise a restoring unit for providing an external force to move the sub-main unit to an original position when an external force is applied to the sub-main unit to which an external force has been applied.

The present invention also relates to a fire detection unit for sensing environmental changes related to a fire; And a power unit for changing the position of the intermediate unit based on fire information of the fire sensing unit. In this case, the main body unit can not be moved when the intermediate unit is in the locked position, and when the intermediate unit is in the released position And the power unit may be configured to move the position of the intermediate unit from the locked position to the released position based on the fire information of the fire sensing unit.

According to an embodiment of the present invention, it is possible to further include a power unit for generating a current based on fire information of the fire sensing unit. In this case, the main body unit can not be moved when the intermediate unit is in the locked position, Wherein when the fire information is provided by the fire detection unit, the intermediate unit is moved from the lock position to the movement position by the current of the power unit, even if no external force is applied to the sub-body unit, The main body portion may be configured to be moved from the fixed position to the moving position.

The present invention may further include a sub-part that is mediated with the intermediate part and provides an external force to the intermediate part so that the position of the intermediate part is maintained in the locked position when no external force is applied to the main body part In this case, the power unit is configured to cause a current to flow in the sub-unit so that external forces provided by the sub-unit to the intermediate unit are different from each other depending on whether fire information is provided by the fire sensing unit, When it flows, the temperature may rise and contract.

According to the door holder according to the present invention, the user can conveniently operate the door holder.
