Abstract

PROBLEM TO BE SOLVED: To provide a door stop capable of keeping a door open when a lock plate is attracted by a magnet, the door stop being configured to hold the door at a predetermined position.SOLUTION: A door stop comprises a door stop body incorporating a magnet and a lock plate formed from a corresponding magnetic substance. In a lock, a locked part formed from a transparent window including an opening edge in parallel with a horizontal support shaft is formed in a distal end portion. The door stop includes a lock protrusion having such a length that a distal end portion of a locked body in which the magnet raises the lock plate with a magnetic force, can be inserted and locked with movement of a door and a distal end face is settled along the opening edge, has such an energizing force that the lock protrusion is pushed away by a distal end portion of the lock plate, and keeps an opening state of the door by engaging the lock part and the locked part. When a force exceeding a sum of the magnetic force and the energizing force acts on the door, the lock protrusion is removed from the locked part and disengaged from the locked part, and the door stop body and the lock are disengaged.

Description

  The present invention relates to a door stop capable of releasably holding an open door in a predetermined open position.

  Conventionally, a door stop that can be held in a predetermined open position when the door is opened and can be closed as it is is known. It is possible to release the holding state with a simple operation just by moving it to the door body, for example, a door-to-door body with a magnet built in the case body installed at the bottom of the door, and a magnetic body on the pedestal installed on the floor Japanese Patent Application Laid-Open No. 10-115139 and Japanese Patent Application Laid-Open No. 11-11 are made of a locking plate in which a locking plate having a distal end portion slidable in a vertical direction by a horizontal support shaft disposed at a base end portion of the locking plate. No. 287062 and the like.

  However, the door stop proposed in the above publication is to fix the door to the floor surface by the attractive force of the magnet. For example, in the case of strong winds, the door should be held in a predetermined open position. There was a problem that the holding state was released.

  Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 2003-20848, a door-contact main body in which a magnet is built in a case body installed at the lower part of a door, and a base made of a magnetic material on a pedestal installed on a floor surface. The stopper plate is a door stop composed of a locking member whose tip end portion is disposed so as to be swingable in the vertical direction by a horizontal support shaft disposed at the base end portion, and the locking tool is disposed at the tip end portion of the horizontal support shaft. The door-contact main body has an inclined surface for allowing the magnet to stand obliquely with a magnetic attraction force, and the door-standing main body stands up diagonally. The door stop which the front-end | tip part of the made to-be-latched body fits and latches the to-be-latched part formed in the said latching plate in the latching recessed part with the movement of a door is shown.

  In this conventional door stop, the locking member does not protrude from the floor when not in use, and unlike the case of simply adsorbing by magnetic force, a stepped portion formed at the tip of the plate is installed in the door stop body. The door is kept in the open state even when an external force such as wind is applied from the outside of the door because the locking state is retained by the urging force of the spring. Has the advantage of being able to.

  However, in this conventional door stop, the engagement between the stepped locked portion and the locking recess is held by pressing the locked portion with a hook-shaped locking portion having a locking recess. There is a problem that the holding power is not sufficient.

And a locking tool arranged such that the tip part is swingable in the vertical direction by a horizontal support shaft arranged in the part, and the locking tool is mounted on the door-holding body at a position where the door is opened to a predetermined opening degree. A door stop having a structure in which the locking tool is freely locked and disengaged from below by a locking protrusion formed on the locking tool body in a state of being attracted to a magnet, and a locked portion of the locking tool Comprises a transparent window having an opening edge at least substantially parallel to the horizontal support shaft at the tip, and the door-holding body has an inclined surface for allowing the magnet to stand up obliquely by a magnetic attractive force. , The front end of the object to be locked raised diagonally is moved forward as the door moves. A locking projection having a length that can be fitted and locked to the transparent window along the opening edge of the locked portion formed on the locking plate and has a length that fits along the opening edge of the transparent window. And the engagement of the locking portion of the locking plate with the locked portion has an urging force toward the magnet from which the locking projection is pushed away by the distal end portion of the locking plate. The door is held open by applying resistance to the movement of the door, and when the closing force larger than the sum of the magnetic attraction force and the biasing force is applied to the door in that state, the locking projections are Withdrawing from the locked portion against the urging force, the engagement with the locked portion is released, the engagement between the door stop main body and the locking tool is released, and the door is closed. Features.

  Further, in the present invention, when the thickened reinforcing portion is formed at the distal end portion of the locked body, the durability increases, and the reinforcing portion is formed excluding the portion of the locked portion. If it is, there is no effect on locking.

  According to the present invention, the locking member is very simple, has good operability, is suitable for mass production, and can particularly hold the door in an open state with a large holding force.

A door stop 1 is formed by, for example, a door stop main body 3 and a floor surface 4 installed at a lower portion of a side surface 21 on a pulling side of a door 2 in a hinged door. It is comprised from the securing tool 5 installed.

  The door stop main body 3 is, for example, a bowl-shaped locking member rotatably supported on a case body 31 formed of, for example, a hard synthetic resin or metal by a magnet 32 and a support shaft 35 disposed in the central portion. 34. The locking member 5 has a distal end portion which is vertically moved by a horizontal support shaft 53 which is disposed at a base end portion of a locking plate 52 formed by processing a metal band as a magnetic body on the base 51. A locked portion 55 made of a transparent window having an opening edge 54 at least substantially parallel to the horizontal support shaft 53 is formed at the distal end portion of the locking plate 52.

  The door stop main body 3 has an inclined surface 321 for allowing the bottom surface of the magnet 32 to stand up obliquely by the magnetic attraction force of the locking plate 52, and the tip surface is substantially square at the tip. A hook-shaped locking member 34 formed with a locking projection 33 having a length that can be inserted and inserted along the opening edge 54 of the portion is rotatably supported by a support shaft 35. The locking protrusion 33 is pressed against the inclined surface 321 of the magnet 32 by being biased in the distal direction by a coil spring 36 on the proximal end side of 34.

  As shown in FIG. 4A, the present embodiment having such a configuration attaches the door-holding body 3 to the lower part of the side surface 21 on the pulling side of the door 2 in the hinged door, and locks the fixture 5 on the floor surface 4. Is attached.

  When the door is opened, as shown in FIG. 4 (b), the magnet 32 causes the locking plate 52 to be attracted to the inclined surface 321 by a magnetic attraction force, and stands up obliquely.

  Further, when the door is opened, as shown in FIG. 4C, the distal end portion of the locking plate 52 raised obliquely moves the distal end of the locking plate 52 to the coil spring 36 as the door moves. The latch 2 is inserted between the latch projection 33 and the inclined surface 321 of the magnet 32 against the urging force of the magnet 32. It is held in a predetermined open position.
