  By the way, safety fences are classified into "fixed type" which is roughly divided and fixed to a wall etc. and "standing type" which is only placed on the floor. Among these, the fixed type does not cause any particular problem even if the above-mentioned lock mechanism is adopted. On the other hand, in the case of the stationary type, when the door is lifted, the entire safety fence may be lifted at the same time, and the lock may not be released. Therefore, the lock mechanism that lifts the door to release the lock is not compatible with the stationary safety fence and can not be adopted as the stationary safety fence despite being highly convenient for the user.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a safety fence provided with a lock mechanism that lifts a door and releases a lock while being a stationary type.

  According to this configuration, the lock can be released while the user steps on the leg. In this case, the door frame is pressed against the floor at the time of the lock release, so that the door frame can not be lifted. Therefore, the above-mentioned safety fence can adopt a lock mechanism which lifts a door and releases a lock while being a stationary type.

  Further, in the above-described safety fence, the leg portion may be provided over the entire width of the door.

  According to this configuration, since the user always steps on the leg when standing in front of the door, the user can reliably release the lock while stepping on the leg.

  Further, the safety fence further includes a flap located on the outer side in the width direction of the door frame, wherein the lower end portion of the flap is in contact with the floor surface and pivots around a pivot axis extending in the vertical direction. May be

  According to this configuration, it is possible to prevent the safety fence from falling to one side by rotating the flap by a predetermined angle, and hence the leg on one side can be omitted.

  Further, in the above-mentioned safety fence, the flap has an abutting portion having a circular cross section in the widthwise outer portion, and the outer diameter of the abutting portion is a portion adjacent to the widthwise inner side of the abutting portion. It may be made to be larger than the thickness of

  According to this configuration, since the outer diameter of the contact portion is larger than the thickness of the other portion, for example, when the safety fence is installed on the wall, the contact portion is easily in close contact with the wall, and the contact portion and the wall It is possible to prevent a gap from occurring.

  According to the above configuration, it is possible to provide a safety fence provided with a lock mechanism that lifts the door and releases the lock while being a stationary type.

FIG. 1 is a front view of the safety fence 100, and FIG. 2 is a plan view of the safety fence 100. In the following, the left and right direction in the drawing of FIG. 1 will be referred to as the “width direction” of the safety fence 100, and the front and back sides of the drawing in FIG. 1 will be referred to as the “front side” and “rear side” of the safety fence 100, respectively. Do.

  As shown in FIG. 1, the safety fence 100 includes a door 10 positioned at the center in the width direction, a door frame 20 disposed to surround the door 10, and a hinge mechanism 30 connecting the door 10 and the door frame 20 (see FIG. 3), a lock mechanism 40 (see FIG. 3) for preventing the door 10 from opening, leg portions 50 for supporting the safety fence 100 not to fall down, and flaps 60 located on both sides in the width direction of the door frame 20. And have. Hereinafter, each of these components will be described in order.

  The door 10 is a so-called "open door" configured to open on the front side and the back side (see the dashed line in FIG. 2). In the door 10, the left side in the drawing of FIG. 1 is the “hanging side” corresponding to the rotation axis, and the right side in the drawing of FIG. 1 is the “door tip side” opposite to the rotation axis. The door 10 has an opening 11 at an upper portion in the center in the width direction, and a grip 12 extending in the width direction is formed above the opening 11. The grip portion 12 is used by the user to lift the door 10 and to open and close the door 10. Moreover, the center part of the door 10 is formed in a grid shape, and the appearance of the back side can be confirmed from the front side through this part, and the appearance of the front side can be confirmed from the back side.

  The door frame 20 is a portion that supports the door 10 rotatably and vertically movable via the hinge mechanism 30. When the door 10 is lifted from the state shown in FIG. 1, the door 10 moves upward with respect to the door frame 20 as shown in FIG. Further, the door frame 20 extends in the vertical direction to support the door 10, the hanging portion 21 extends in the vertical direction and faces the hanging portion 21, and the door tip 22 is positioned below the door 10 and is suspended It has a bottom portion 23 connecting the lower end portion of the portion 21 and the lower end portion of the door tip portion 22, and is formed in a U-shape as a whole.

  As shown in FIG. 3, the hinge mechanism 30 is provided on the two stems 31 located on the hanging side of the door 10 and extending in the vertical direction, and the hanging stem 21 of the door frame 20, and the above-mentioned stems 31 are inserted. And two cylindrical portions 32 in which the insertion holes 34 are formed. Among these, the shaft portion 31 is provided on the lower surface of the base portion 33 which protrudes outward in the width direction from the portion on the hanging side of the door 10. Moreover, the upper cylinder part 32 is provided so that it may protrude toward the door 10 from the hanging part 21 among two cylinder parts 32, and the cylinder part 32 of the lower part crosses the hanging part 21 and the bottom part 23 It is provided at the corner.

  The lock mechanism 40 has a projection 41 provided on the lower surface of the door 10 and a lock hole 42 formed in the bottom 23 of the door frame 20. The protrusion 41 is located on the door tip side of the door 10 and protrudes downward, and the lower end is formed in a hemispherical shape. The projection 41 is movable in the vertical direction with respect to the bottom 23 and biased downward. When the open door 10 is closed and the projection 41 contacts the bottom 23 of the door frame 20, the projection 41 is pushed upward. Then, when the door 10 is further closed and the projection 41 reaches the lock hole 42, the projection 41 is biased downward and inserted into the lock hole 42. In this state, even if the door 10 is to be opened, the projection 41 can be caught in the lock hole 42 so that the door 10 can not be opened. That is, the door 10 is in a locked state. However, when the door 10 is lifted from this locked state, as shown in FIG. 3, the projection 41 can come out of the lock hole 42 and open the door 10. That is, the lock of the door 10 is released. Thus, the lock mechanism 40 of the present embodiment is unlocked by lifting the door 10. In addition, the lock mechanism 40 should just be what unlock | releases by lifting the door 10, and does not need to be the above structures.

  The leg part 50 is a part which supports the door frame 20 and prevents the safety fence 100 from falling down. In the present embodiment, the leg portion 50 is provided only on the front side of the door frame 20 and is not provided on the back side. The leg portion 50 is formed in a plate shape, is fixed to the lower end of the bottom portion 23 of the door frame 20, and extends horizontally in a direction perpendicular to the door 10 from the front side. The outer edge portion of the leg portion 50 is inclined so as to decrease in height toward the outside. Therefore, it is difficult for a toddler or a pet to trip at the outer edge portion of the leg 50.

  Further, the leg portion 50 substantially coincides with the widthwise center position of the door 10 and has a widthwise dimension corresponding to the widthwise dimension of the door 10. That is, the legs 50 are provided across the entire width of the door 10. In the present embodiment, the widthwise dimension of the leg 50 is slightly larger than the widthwise dimension of the door 10, but may be the same as or slightly smaller than the widthwise dimension of the door 10. Further, although the leg portion 50 of the present embodiment is formed of resin, the leg portion 50 may have a plate-like shape, for example, a sheet may be stretched on a rectangular frame member. In addition, if the leg part 50 is made to be able to rotate and fold up, the safety fence 100 can be accommodated compactly.

  The flap 60 is located on the widthwise outer side (left side in the drawing of FIG. 1) of the hanging portion 21 and on the outer side in the width direction of the door tip 22 (right side on the drawing of FIG. 1). Each flap 60 has substantially the same vertical dimension as the door frame 20, and the lower end portion is in contact with the floor surface. Each flap 60 has a longitudinally elongated shape whose widthwise dimension is smaller than the vertical dimension. Further, as shown in FIG. 2, each flap 60 has an abutting portion 67 having a circular cross-section on the outer side in the width direction. The outer diameter of the contact portion 67 is larger than the thickness of the inward portion 68 adjacent to the inner side in the width direction of the contact portion 67.

  The flap 60 on the side of the hanging portion 21 (the left side in FIG. 1) has two flap support portions 62 projecting toward the door frame 20, and a vertically central portion supported by each flap support portion 62 and extending vertically And three flap shaft portions 63. Further, in the hanging portion 21 of the door frame 20, groove-shaped door frame bearing portions 66 extending in the vertical direction are formed at two places, and the flap shaft portions 63 described above are respectively provided in these door frame bearing portions 66. It is inserted. As a result, the flap 60 on the side of the hanging portion 21 can be pivoted about a pivot extending vertically through the flap bearing 61 and the door frame shaft 65.

  Grooved flap bearings 61 extending in the vertical direction are formed at two locations on the flap 60 on the door tip 22 side (right side in FIG. 1). Further, in the door tip portion 22 of the door frame 20, two door frame support portions 64 projecting outward in the width direction, and two vertically extending middle portions supported by the respective door frame support portions 64 in the vertical direction And a door frame shaft portion 65. The door frame shaft portions 65 are respectively inserted into flap bearing portions 61 of the flaps 60 located on the door tip 22 side. As a result, the flap 60 on the door tip 22 side can be pivoted about a pivot axis extending vertically through the flap bearing 61 and the door frame shaft 65.

  The above is the structure of the safety fence 100 according to the present embodiment. The safety fence 100 according to the present embodiment can be installed at the entrance of a corridor or a room, and can also be installed in front of a rack 101 such as a TV stand or a book shelf as shown in FIG. As shown in FIG. 4, in order to install the safety fence 100 in front of the rack 101, the safety fence 100 is disposed so that the rack 101 is positioned on the back side of the safety fence 100, and both flaps 60 are turned to the back side. The contact portion 67 is brought into contact with the rack 101 by movement. If it installs in this way, since the leg 50 supports the door frame 20 in the front side of the safety fence 100, the safety fence 100 does not fall to the front side. Moreover, since the flap 60 supports the door frame 20 from the back side of the safety fence 100, the safety fence 100 does not fall down on the back side.

  Further, as described above, the outer diameter of the contact portion 67 located in the width direction outer portion of the flap 60 is larger than the thickness of the inward portion 68 adjacent to the width direction inner side of the contact portion 67. In the case shown, the contact portion 67 can be easily brought into close contact with the rack 101 regardless of the rotation angle of the flap 60. Therefore, it is possible to prevent a gap from being generated between the safety fence 100 and the rack 101, and to prevent an infant or a pet from entering the front side of the rack 101 from the gap between the safety fence 100 and the rack 101.

  Furthermore, although the lock mechanism 40 of this embodiment is unlocked by lifting the door 10, in the case of a stationary safety fence, when the door 10 is lifted, the door frame 20 may be lifted together. However, according to the present embodiment, when the user lifts the door 10, since the user stands on the front side of the door 10, the user steps on the leg 50 located on the front side of the door 10. Therefore, even if the door 10 is lifted, as a result of the door frame 20 being pressed against the floor by the leg 50 that the user steps on, the lock can be reliably released.

  In addition, although the leg part 50 is provided only in the front side of the door frame 20 and is not provided in the back side, the safety fence 100 which concerns on this embodiment has the flap 60 as mentioned above. Therefore, if the flap 60 is turned to the back side, the safety fence 100 does not fall to the back side. Therefore, the safety fence 100 is installed so as not to fall down even if the leg 50 can not be provided on the back side of the safety fence 100, for example, in a place where there is a step on the floor which is the back side. be able to.

  However, the safety fence 100 may be provided with legs 50 on both the front side and the back side of the door frame 20. At that time, the leg 50 described above may be provided on the front side of the door frame 20, and a leg different from the leg 50 described above may be provided on the back side. For example, a rod-like member extending in a direction perpendicular to the door 10 or the door frame 20 may be provided as a leg, or a rectangular frame-shaped leg 80 as shown in FIG. 5 may be provided. In addition, if leg parts 50 and 80 are constituted so that attachment or detachment to door frame 20 is possible, according to the installation place of safety fence 100, leg parts 50 and 80 can be attached or removed. It is possible to improve the quality.

  Moreover, although the case where each flap 60 was formed of one member was demonstrated in the safety fence 100 mentioned above, the flap 60 may connect and form several members. For example, as shown in FIG. 6, the flap 60 may be formed by joining together a first plate member 69 and a second plate member 70 having different dimensions in the width direction. In this case, the second plate 70 may be movable relative to the first plate 69. Even in the case shown in FIG. 6, if the widthwise outer portion of the second plate member 70 located on the outer side in the widthwise direction is the contact portion 67 having a circular cross section, the space between the safety fence 100 and the wall etc. Can prevent the formation of gaps.
