Hereinafter, the present invention will be described in more detail with reference to the drawings.
A protection gate according to an embodiment of the present invention is shown in FIG. This protection gate is attached to the existing door A, and is fixed to the existing door A in a detachable manner with the gate door 1, the two rotary shafts 2 provided on one side of the gate door 1, and the rotary shaft 2 Are provided at the tip of the dropping member 4, a dropping member 4 as a movable member that can be moved back and forth from the gate door 1 to the indoor floor where the existing door A is provided, and A suction cup 5 as a deterrent member that is detachably bonded to the floor, a magnetic holding tool 6 provided on the other side of the existing door A, and a magnet 7 provided on the gate door 1 and attracted to the magnetic holding tool 6. Have.

  The rotating shaft 2 and the bearing 3 constitute a rotating member that rotatably supports the gate door 1 at one side of the existing door A. The dropping member 4 and the suction cup 5 constitute a rotation stopping mechanism that stops the rotation of the gate door 1. Moreover, the magnetic clamping tool 6 and the magnet 7 constitute an integrated mechanism for detachably bonding the existing door A and the gate door 1. In addition, the existing door A faces the hallway of the width | variety equivalent to the width | variety of a door, and an indoor floor is a wooden floor where the surface is comprised with the decorative board.

  The gate door 1 is formed with a width slightly narrower than the width of the existing door A, and is formed with a height of about 1 m. The gate door 1 is formed with an accommodating portion 8 that is an L-shaped depression for accommodating the dropping member 4 (see FIG. 2). In order to guide the dropping member 4 to advance and retreat downward, the accommodating portion 8 forms a cylindrical passage by closing one surface side of the gate door 1 at the lower part of the gate door 1.

  As shown in FIGS. 3 and 4, the bearing 3 includes a base 9 that is detachably held by an existing door A, and a cylinder 10 that is fixed to the base 9 and into which the rotary shaft 2 is inserted. The base portion 9 is formed of a rigid material such as stainless steel, and is formed into a shape having a three-sided cross-sectional shape that is fitted to one side of the existing door A. The base 9 has a thickness of about 2 mm, which is thinner than the allowable distance between the existing door A and its frame. Further, the distance between the two opposing surfaces in the base portion 9 is about 5 mm thicker than the existing door A. Each of the two opposing surfaces of the base 9 is provided with a through hole, and a screw is cut on the inner peripheral surface of the through hole. Bolts 11 and 12 that are screwed into the screw are respectively inserted into the through holes. Is inserted.

  The cylinder 10 is fixed to the base 9 by a support part that protrudes from the surface of the base 9 and supports the cylinder 10 at a predetermined distance. Bolts 11 and 12 are both hexagon socket head bolts, and the diameters of the tips of bolts 11 and 12 are about 10 mm. The length of the bolt 11 is shorter than that of the bolt 12, for example, the length of the bolt 11 is about 5 mm, and the length of the bolt 12 is about 10 mm. The bearing 3 is fixed to the existing door A so as to be detachable by advancing the bolts 11 and 12 toward the existing door A and sandwiching them by the bolts 11 and 12.

  The magnetic holding tool 6 is formed by a magnetic material such as iron so that the cross-sectional shape is a three-sided rectangular shape, and is slightly biased in the direction in which the two opposing surfaces approach each other. It is formed so that. The magnetic clamping tool 6 is formed such that the distance between two opposing surfaces of the magnetic clamping tool 6 is a distance slightly longer than the thickness of the existing door A (about 1 to 2 mm). Further, the two opposing surfaces of the magnetic clamping tool 6 sufficiently protrude from the surface connecting the magnet 7 so as to partially overlap (half or more) or entirely when viewed from the gate door 1 side.

  The magnet 7 is embedded in both the front and back sides of the gate door 1 at the upper end of the other side of the gate door 1.

  The protective gate of FIG. 1 is accommodated integrally with the existing door A by the magnetic force of the magnet 7. When the gate door 1 is rotated against the magnetic force of the magnet 7, the gate door 1 is freely rotated. For example, when the gate door 1 rotates to a desired opening degree such as 90 degrees, the dropping member 4 is rotated and moved downward, and the suction cup 5 is sucked to the floor. As a result, the gate door 1 is fixed at a desired opening (see FIG. 6). In this way, the corridor in front of the existing door A is closed by the gate door 1, and the passage of infants is restricted.

  When the suction cup 5 is peeled off the floor, the gate door 1 freely rotates again. When the dropping member 4 is pulled up and rotated to be accommodated in the accommodating portion 8 and the gate door 1 is rotated to the existing door A, the gate door 1 is integrated with the existing door A by the magnetic force of the magnet 7. .

  In the case where the floor is a carpet, the rotation of the gate door 1 can be stopped by providing a member provided so that the hook-and-loop fastener comes into contact with the floor when the dropping member 4 advances downward instead of the suction cup 5. it can.

  Moreover, if the accommodating part 8 is configured so that the gate door 1 is cut out in an L shape and is closed from both the front and back of the gate door 1 at least at the lower end of the gate door 1, it is dropped from both the front and back of the gate door 1. It becomes possible to advance the member 4 downward and accommodate it upward.

  In this embodiment, the bearing 3 is fixed to the hinge side of the existing door A, and the gate door 1 is rotated in the same direction as the rotation direction of the existing door A. It is also possible to use the bearing 3 in the same manner by fixing the bearing 3 to the door knob side.

  Since the protective gate of this embodiment has the gate door 1, the rotating shaft 2, the bearing 3, the dropping member 4, the suction cup 5, and the accommodating part 8, it can be attached to the existing door A so that attachment or detachment is possible. Since the existing door A is usually provided so as to separate indoors, it is a protective gate at appropriate indoor places (for example, in front of water facilities such as bathrooms and washrooms, doors of passages leading to stairs, etc.) Can restrict the traffic of infants.

  Since the bearing 3 is composed of the base 9, the cylinder 10, and the bolts 11, 12, the protective gate does not damage the existing door A by sandwiching the existing door A with the bolts 11 and 12. A protective gate can be attached detachably.

  Since the protective gate has the bolts 11 and 12, the bearing 3 can be fixed to the existing door A with sufficient strength. Further, by making the bolt 12 longer than the bolt 11, it is possible to sufficiently adjust the fixing of the bearing 3 by the bolt 12 on the side opposite to the cylinder 10 side on which the gate door 1 is provided. The bearing 3 can be detachably fixed to the existing door A in response to a slight change in the thickness of the existing door A.

  Since the protective gate has the magnetic clamping tool 6 and the magnet 7, the gate door 1 can be fixed to the existing door A integrally and detachably. Accordingly, the gate door 1 can be prevented from rotating when the protective gate is not used, and the existing door A can be used regardless of the wearing of the protective gate.

  Since the protective gate has the magnetic clamp 6, the magnetic material can be easily installed on the existing door A and without damaging the existing door A.

  The protective gate of the present invention may be a bearing 21 shown in FIG. 7 instead of the bearing 3 and a gate door 22 shown in FIG. 8 instead of the gate door 1. The bearing 21 is configured in the same manner as the bearing 3 except that a cylinder 25 is used instead of the cylinder 10. The cylinder 25 includes a notch portion 23 into which the rotary shaft 2 is fitted at a rotation position of the gate door 22 when the gate door 22 is parallel to the existing door A, and a gate when the gate door 22 is rotated 90 °. A notch portion 24 into which the rotary shaft 2 is fitted is formed at the rotation position of the door 22.

  The gate door 22 is the same as the gate door 1 except that the dropping member 4, the suction cup 5, the housing portion 8, and the magnet 7 are not formed and a handle 26 is provided at the center of the upper edge of the gate door 22. It is constituted similarly. The handle 26 is formed by a through hole at the center of the upper end of the gate door 22. In addition, in the existing door A, the magnetic clamping tool 6 is removed.

  When the gate door 22 is in a position in parallel with the existing door A, the rotary shaft 2 is fitted into the notch 23, the rotation of the gate door 22 is stopped, and the gate door 22 is in parallel with the existing door A. Fixed in position. When the gate 26 is rotated while holding the handle 26 and slightly lifted, the gate door 22 rotates. When the gate door 22 rotates 90 °, the rotary shaft 2 is fitted into the notch 24, the rotation of the gate door 22 is stopped, and the gate door 22 is fixed at a position perpendicular to the existing door A, Infant traffic in the hallway in front of the existing door A is restricted.

  The notch part formed in the cylinder 25 is not limited to two, and may be further provided. Further, when a stopper such as a disk or nut having a diameter larger than the inner diameter of the cylinder 25 is attached to the tip of the rotating shaft 2 by being screwed into a screw formed at the tip of the rotating shaft 2, for example, the gate door This is more effective from the viewpoint of preventing the gate door 22 from falling off the bearing 21 when the 22 is rotating.

  This protective gate is provided at the predetermined rotation position of the gate door 22 without providing a member that stops the rotation of the gate door in relation to the indoor floor or wall, such as the dropping member 4 or the fence. The rotation can be stopped. Accordingly, it is possible to restrict the passage of infants indoors with a simple configuration that does not include a member such as a dropping member. Further, since the rotation of the gate door 22 is stopped without acting on the indoor floor or wall, it is more effective from the viewpoint of regulating the passage of infants indoors regardless of the material of the floor or wall.

  The protective gate of the present invention can be detachably attached to an existing door. Since the existing door is generally appropriately provided according to the indoor structure, it is possible to easily perform appropriate regulation of infant traffic according to the indoor life. Particularly in the so-called “follow-up” period around the age of one year, it is preferable from the viewpoint of balancing indoor life and traffic regulation for protecting infants.

  Moreover, since the existing door is detachably attached without damaging the door, damage to the wall related to the installation can be suppressed as compared with the conventional protective gate. Since the protection gate is required for several years, the protection gate that is less damaged by such installation is particularly suitable for use in rental or newly built houses.
