[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper for an open door for closing an open door of a cabinet or the like which can be opened and closed via a hinge on a front surface of the cabinet, for example.
More particularly, the present invention relates to a door door stopper that cannot be easily opened and closed by an infant or the like and can be temporarily locked so that the infant or the like does not inadvertently open and close and cause injury.

[0002]

2. Description of the Related Art An opening door made of, for example, glass provided on the front surface of a cabinet is provided with an engaging projection on the upper or lower part of the opening door in advance, and the engaging projection is provided on an engaged member provided on the cabinet side. Is engaged during closing so as not to open normally, and when opening it, it does not require much force and can be easily opened by picking a knob or the like and pulling it forward. For this reason, there is a possibility that the door may be opened carelessly when an infant or the like tries to stand up by holding the knob. Therefore, there is a possibility that the head may be hit on the door that is about to open, or the posture may be lost due to the open momentum, a force may be applied in the closing direction, and the door may be pinched.

[0003] Therefore, such an opening door is temporarily fixed,
Various stoppers have been conventionally provided that cannot be opened by an infant or the like, but can be unlocked by an adult.

[0004]

[Problems to be Solved by the Invention] However, while it is difficult for an infant to operate, an adult is required to have two contradictory surfaces that can easily release the lock when necessary. It is complicated and difficult to handle because the operability of the adult is sacrificed.

[0005] The purpose of this invention is made in view of the situation of the prior art as described above. The purpose of this invention is to make it difficult for an infant or the like to operate, and to unlock the lock by an extremely simple operation for an adult. To provide a stopper for a hinged door.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide an opening door stopper for closing an opening door of a cabinet or the like which can be freely opened and closed via a hinge member, one end of which is rotatably supported. A closing rod provided with a locking member made of a magnet at the other end so as to be able to advance and retreat, a support means for rotatably supporting the one end of the closing rod, and a fixing means for fixing to the surface of the opening door. The first mounting member having the fixing means, the locked portion to which the locking member can be locked, and the magnet of the locking member locked to the locked portion have different polarities when locked. A lock operation means for operating to have the same magnetic pole at the time of unlocking, securing and unlocking the lock member, and a fixing means for fixing to the surface of the opening door. This is achieved by comprising two mounting members.

[0007] The locking operation means is a slide member which is supported in parallel with different polarities of the magnets and which is slidable in a direction substantially perpendicular to the direction in which the magnets are arranged via the operation portion, or Alternatively, a rotating member that supports the magnet so that different magnetic poles come in the circumferential direction and rotatably supports the magnet via the operation unit can be used.

[0008]

The door stopper is mounted on the front side of the door by first and second mounting means by means of fixing means, for example, adhesive tape. When the door is opened, the closing rod is suspended from the first mounting member because one end is not restrained. Next, the door is closed, the closing rod is rotated toward the second mounting member, and the locking member is locked to the locked portion. At this time, since the polarity of the magnet of the locking member and the polarity of the magnet on the locking operation means side are set to be different, the locking means is securely locked to the locked portion, and the door is closed. State is maintained.

When the door is opened, the magnet on the locking operation means side is made to have a different polarity from the magnet on the locking means side via the locking operation means. As a result, the magnet on the locking means side is retracted, the locked state is released, and the restraint on the door is released.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a use state of a door stopper according to a first embodiment of the present invention. In the figure, a stopper 1 includes a first mounting member 3 to which one end of a closing rod 2 is rotatably mounted, and a second locking operation member 4 detachably engaging with the other end of the closing rod 2. The mounting member 5 is basically configured.

As shown in FIG. 2, the first mounting member 3 rotatably supports the closing rod 2 via a rotating shaft 6, and together with the second mounting member 5, the first and second mounting members 3, 5 Are fixed to the opening doors 9 and 10 by adhesive tapes 7 and 8 provided on the back surfaces of the doors. This fixed position can be freely selected by the user. In this case, the relative positions of the first and second attachment members 3 and 5 are uniquely determined according to the length of the closing rod 2. The doors 9 and 10 are attached to the front of the cabinet so as to be freely opened and closed by hinges (not shown).

A bar-shaped first magnet 11 is slidably and undetachably attached to the distal end of the closing rod 2. That is, in this embodiment, the first magnet 11
The end 12 on the N-pole side is slightly enlarged and is set so as to be slidable only in the slide groove 13 formed in the closing rod 2. A notch 15 is provided in the upper portion on the S pole side of the first magnet 11 so as to easily engage with the locking groove 14 formed in the above-mentioned second mounting member 5. The locking groove 14 is formed substantially horizontally in the center direction from the side surface of the second mounting member 5, and has a guide surface 16 formed at the entrance end thereof, which is inclined obliquely downward.

A slide groove 17 is formed in the second mounting member 5, and the locking operation member 4 is inserted slidably in the up-down direction. The second and third magnets 18 and 19 are arranged on the locking operation member 4 in parallel at right angles to the sliding direction and with opposite polarities. In this case, since the leading end side of the first magnet 11 is an S pole,
The upper side, that is, the closing rod 2 for the second magnet 18
The side is set to the N pole, and the third magnet 19 is set to the S pole. Thereby, at the time of closing, as shown in FIG. 2, the upper second magnet 18 is magnetically attracted to the first magnet 11, and the closing rod 2 is brought into a restrained state (locked state).

At the time of release, the S-pole of the third magnet 19 is opposed to the S-pole of the first magnet 11 by pushing the locking operation member 4 upward as shown in FIG. 3 to generate a magnetic repulsive force. . The first magnet 11 retreats due to the magnetic repulsion, and its tip is separated from the locking groove 14. By this detachment, the closing rod 2 rotates clockwise in FIG. 3 by the action of gravity, and the opening door 9 by the closing rod 2,
The closed state of 10 is released. When the closing rod 2 rotates downward, the first magnet 11 also moves in the slide groove 13 by the action of gravity, and the S pole side projects again, and finally the two-dot chain line in FIG. Return to the state. Further, the locking operation member 4 is also lowered by gravity and returns to the initial state.

Therefore, when the doors 9 and 10 are to be locked again, the closing magnet 2 can be rotated counterclockwise in FIG. 1 from the state shown by the two-dot chain line in FIG. 11 is retracted when it comes into contact with the guide surface 16 of the locking groove 14, but is attracted when it faces the N pole of the second magnet 18 having a different magnetic pole, so that the locking groove 14 is securely inserted.
And the invaded state is maintained. Thereby, the closed state of the opening doors 9 and 10 is maintained. When the closing rod 2 is in the locked state and there is a possibility that an infant or the like may push the lower end of the locking operation member 4 projecting downward from the second mounting member 5 upward, the third magnet 19 slides. When the lower end of the locking operation member 4 is located at the lower end of the groove 17, the lower end of the locking operation member 4 does not protrude from the lower end of the second mounting member 5.
If it is configured to protrude from the upper surface, the lock cannot be released unless the upper end of the locking operation member 4 protruding upward is picked up, so that the operation is difficult for a child, and the opening doors 9, 10 are mischievously opened. Opening can be prevented.

FIG. 4 shows a second mounting member 5 according to the second embodiment.
FIG. 5 is a cross-sectional view of a main part showing a locked state between the lock lever and a closing rod. In this embodiment, the locking operation member 4 in the first embodiment is set so as to be rotatable instead of sliding, and the fourth magnet is located at a position corresponding to the locking groove 14 of the locking operation member 20. 21 is provided in parallel with the rotation direction R. Other configurations are exactly the same as those of the first embodiment, and the description thereof will be omitted.

In the second embodiment, when closed, as shown in FIG. 4, the S pole of the first magnet 11 and the N pole of the fourth magnet 21 face each other to generate magnetic attraction. Locked. In this state, when the operating portion 22 at the lower end of the locking operation member 20 is operated and rotated by 180 degrees, the S pole of the fourth magnet 21 is opposed to the S pole of the first magnet 11, and a magnetic repulsive force is generated. Therefore, as in the first embodiment, the first magnet 11 is retracted, the first magnet 11 is separated from the locking groove 14, and the closed state is released.

At the time of closing, the N of the fourth magnet 21 is
When the locking operation member 8 is rotated so that the pole faces the S pole of the first magnet 11 and the closing rod 2 is returned to the original state in this state, the locking operation is automatically locked and the opening doors 9 and 10 are opened. It is possible to maintain the closed state.

In this embodiment, the fixing means is constituted by the adhesive tape. However, depending on the material of the opening doors 9 and 10, it may be impossible to obtain a predetermined fixing force with the adhesive tape. In that case, other known fixing means typified by screw means may be employed.

[0021]

As is apparent from the above description, a stopper for an opening door for closing an opening door of a cabinet or the like which can be freely opened and closed via a hinge member is provided. A closing rod which is supported and has a locking member formed of a magnet at the other end thereof, which is capable of moving forward and backward, a supporting means for rotatably supporting one end of the closing rod, and a fixing means for fixing to the surface of the opening door. A first mounting member having fixing means,
The locked portion that can be locked by the locking member and the magnet of the locking member locked to the locked portion have different polarities when locked and have the same magnetic pole when unlocked. Operation,
2. The invention according to claim 1, comprising a locking operation means for securing and releasing the locking of the locking member, and a second mounting member having fixing means for fixing to the surface of the door. Afterwards, the first and second mounting members are opened and fixed to the door,
The opening door can be closed by a simple operation of merely leveling the closing rod, and the locking of the closing rod can be easily released by one-touch operation of the locking operation means. On the other hand, by reducing the size of the locking operation means so that it cannot be operated by an infant or the like, it is possible to prevent the door from being opened carelessly due to the mischief of the infant. The closing rod appears as a bar-shaped member in front of the opening door, and does not impair the aesthetic appearance in design.

The locking operation means is formed of a slide member which is supported in parallel with different polarities of the magnets and which can be slid in a direction substantially perpendicular to the direction in which the magnets are arranged via the operation portion. And a rotating member for supporting the magnet so that different magnetic poles come in the circumferential direction and rotatably supporting the magnet via the operation unit. And unlocking can be performed.
