Description

TECHNICAL FIELD The present invention relates to a safety fence that regulates passage or entry of infants and pets.

Patent Literature 1 below discloses a safety fence that is installed in a passage or a doorway to restrict passage or entry of infants and pets. This safety fence has a door for adults and owners to pass through, and a lock mechanism that locks the door in a closed position to prevent the door from being opened by infants and pets.

In this lock mechanism, when the door is in the closed position, a projection provided on the lower surface of the door enters the lock hole formed in the door frame, thereby locking the door. In the locked state, the door cannot be opened because the protrusion is caught in the lock hole. If the door is lifted, the projection will come out of the lock hole and the lock will be released.

JP 2017-000495 A

In the safety fence equipped with the above locking mechanism, when the open door is closed, the protrusion provided on the bottom surface of the door contacts the door frame and is pushed upward, and when the door reaches the closed position, configured to fit into the lock hole. As described above, when the door is closed, the protrusion contacts the door frame, and the entire door vibrates at this time, which may cause a large impact sound. If a loud impact sound is generated, it is not preferable because it may wake up sleeping infants and pets.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safety fence capable of suppressing impact noise generated when a door is closed.

A safety fence according to an aspect of the present invention includes a first door, a door frame that rotatably supports the first door, a positioning magnet that uses magnetic force to draw the first door to a closed position, and a closed position. and a locking member that locks to the first door at the position to prevent rotation of the first door.

According to this configuration, since the first door is positioned at the closed position using the magnetic force of the positioning magnet, contact between the first door and the door frame or the like can be avoided when the first door is closed. Therefore, according to the above safety fence, it is possible to suppress the impact noise generated when the first door is closed.

In the above safety fence, the locking member is configured to be linearly slidable between a non-locking position in which it is not locked to the first door and a locking position in which it is locked to the first door. good too.

In this configuration, since the locking member is locked to the first door by sliding linearly, compared to the case where the locking member is locked to the first door by rotating, the locking member The impact generated when the door is locked to the first door is small, and the impact noise can be suppressed.

The safety fence described above further includes a second door arranged adjacent to the first door in the width direction, and the door frame extends the width direction end of the first door farther from the second door. The first door is rotatably supported as a suspension base, and the second door is rotatably supported using a width direction end portion of the second door farther from the first door as a suspension base. may

In this configuration, the first door and the second door form a double door. A double door can be smaller in size (that is, turning radius) per door than a single door, so positioning can be performed even if the magnetic force of the positioning magnet is small.

Said safety fence WHEREIN: You may make it the said positioning magnet draw the said 1st door to a closed position, and draw a said 2nd door to a closed position using magnetic force.

Since the double door is composed of two doors, there is a risk that each door will generate an impact sound when the doors are closed. In other words, double doors have the advantage of being easier to pass through than single doors, but have the disadvantage of being prone to impulsive noise. However, according to the above configuration, since both the first door and the second door are positioned using magnetic force, the disadvantage of the double door, which is easy to generate impact noise, is eliminated while maintaining the advantage of easy passage. can be suppressed.

A safety fence according to another aspect of the present invention includes a door having a positioning pin movable in the axial direction or formed with a locking hole into which the positioning pin is inserted, and rotatably supporting the door. A door frame and a locating magnet that uses magnetic force to attract the locating pin to the locking hole when the door is in the closed position.

In this configuration, the door is positioned in the closed position by drawing the positioning pin into the locking hole with the positioning magnet. Therefore, contact between the door and the door frame or the like can be avoided when the door is closed, so that impact noise generated when the door is closed can be suppressed.

According to the above safety fence, it is possible to suppress the impact noise generated when the door is closed.
