Description

  The present invention relates to a furniture overturn prevention device, and more particularly, to a overturn prevention device that is interposed between a relatively tall furniture such as a chest or a cupboard and a ceiling and prevents the furniture from falling over in the event of an earthquake.

  Furniture such as chests and cupboards that have a small front and back width and are large in the vertical direction are likely to fall down in the event of an earthquake and injure residents. Many preventive devices have been developed. For example, a rod-shaped instrument that is interposed between the upper surface of the furniture and the ceiling surface to prevent the furniture from being pressed from the top and falling forward is well known.

  This fall prevention tool is generally called a stick, but its length can be adjusted according to the distance between the top surface of the furniture and the ceiling surface. It is characterized by what it can do. However, since a plurality of bar-shaped members are exposed above the furniture, the appearance is not good, and there is a problem that they are easily dropped due to strong shaking.

  On the other hand, a filler-type anti-tip tool that is placed almost flush with the front and left and right sides of the furniture so as to fill the gap formed between the furniture and the ceiling and exhibits excellent earthquake resistance is also known. It has been. However, since the fall prevention device is configured to completely block the upper part of the furniture, the portion cannot be used for storage, and thus there is a difficulty in effectively utilizing the space.

  Therefore, as described in JP-A-8-150037 and JP-A-2007-143767, a storage box-type tipping prevention tool arranged on the upper surface of furniture has been proposed. These fall prevention tools are provided with a top plate or a contact plate disposed above the top plate so that it can be moved up and down, and are fixed in a state of being close to or in contact with the ceiling surface while being moved up and down manually. By exhibiting a fall prevention function and having an opening / closing door in the storage opening, an excellent storage function can be exhibited without impairing the appearance of the furniture.

  However, because the door uses a double door system in which the door plate is hinged to the left and right side plates, the hinge strength of the two door plates is ensured when the lateral width of the storage room is large. In order to ensure strength, the arrangement space is insufficient to provide two hinge members per door plate to ensure the strength, and even if it can be arranged, the cost is likely to increase. For this reason, there is currently no product corresponding to a narrow gap where the distance between the upper surface of the furniture and the ceiling surface is 24 cm or less.

  As a means to deal with such a narrow gap, a method can be considered in which the door plate is a horizontally long single plate, which is hinged to the top plate side and opened and closed up and down. When the door is opened, the thickness of the top plate and the door plate provided on the top plate becomes even narrower. Therefore, the storage function is easily impaired, and the height adjustment work is performed by inserting a hand from the opening to the back of the storage chamber. Tends to be a difficult situation.

JP-A-8-150037 JP 2007-143767 A

  The present invention is intended to solve the above-described problem, and the furniture overturn prevention device that is interposed between the furniture and the ceiling and exhibits a fall prevention function and a storage function has a narrow gap above the furniture. Even in such a case, it is an object to enable easy installation without deteriorating the appearance.

  Therefore, the present invention is arranged in a gap of 24 cm or less in the vertical width formed between the upper surface of the furniture and the ceiling surface, and the contact plate is brought close to or in contact with the ceiling surface by a predetermined lifting mechanism. In addition to exhibiting a fall prevention function, it has a storage room formed between a pair of side plates erected on both the left and right sides of the bottom plate placed on the upper surface of the furniture and having an opening / closing door at the front opening end. In the furniture overturn prevention device that exhibits the above, the storage chamber is opened upward from the opening end to at least the center position in the front-rear direction, and the door is hinged to the opening end side of the bottom plate with the door plate at the lower end side. It is a downward opening method that is hinged with a member and opens downward, and its lifting mechanism is arranged on the back side of the storage room, and a hand is inserted into the storage room from the opening end with the open / close door open. By operating the lifting mechanism And it shall be characterized in that the height adjustment is made contact plate is moved up and down.

  As described above, in a situation where the gap from the top surface of the furniture to the ceiling surface is narrow, it is difficult to provide a door plate that hides the interior of the storage room in a double-spread type, and the top-open type that attaches the door plate to the top plate side Even in this case, the vertical width of the opening end of the storage chamber becomes substantially narrow due to the presence of the top plate and the door plate, making it difficult to perform the storage work and up to the operation unit of the lifting mechanism on the back side of the storage chamber It is difficult to insert and operate a hand. On the other hand, in the present invention, by adopting the lower opening type in which the door plate is hinged to the bottom plate, the upper end of the opening is opened and the door can be widely used up and down with the open / close door open, so that it can be easily stored. In addition, since the height of the contact plate can be easily adjusted, the installation work is extremely easy.

  Further, in the furniture overturn prevention device described above, the lifting mechanism has a bolt shape provided vertically at least on both the left and right ends of the installation plate provided on the back side of the storage room with the pair of side plates provided to the left and right. The abutting plate is supported on the upper end side of the member, and the abutting plate is moved up and down by rotating a nut-like member screwed to the bolt-like member by a predetermined means. With this feature, it is possible to realize an easy raising / lowering operation and fixing of the height position of the contact plate with a simple configuration.

  Furthermore, in the furniture overturn prevention device described above, a locking mechanism for fixing the open / close door in a closed state is provided at a predetermined position near the opening end of the side plate and a predetermined position of the door plate corresponding thereto. Thus, it is possible to prevent the opening / closing door from opening unexpectedly due to the shaking of the earthquake and dropping the articles in the storage room.

  In this case, the lock mechanism is such that an operation button for locking and unlocking is exposed on the front surface of the door plate, and this operation button projects from the front surface and also serves as a door opening / closing knob. If it is characterized by this, the locking operation and the unlocking operation can be performed simultaneously with the opening / closing operation of the door.

  According to the present invention in which the door plate is hinged to the bottom plate so as to be opened downward, it can be easily installed without impairing the appearance even when the gap above the furniture is narrow.

It is a longitudinal cross-sectional view which shows the installation state of the furniture fall prevention tool which is embodiment in this invention. It is a front view of the furniture fall prevention tool of FIG. It is a front view which shows the state which closed the door of the furniture fall prevention tool of FIG. It is a front view which shows the state which lowered | hung the contact plate of the furniture fall prevention tool of FIG. It is a longitudinal cross-sectional view which shows the state which has mounted | wore the installation work of the furniture fall prevention tool of FIG.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a longitudinal sectional view showing a state in which the furniture overturn prevention device 1 according to the present embodiment is disposed and interposed between the upper surface of the cupboard 200 and the ceiling 100, and FIG. 2 shows the furniture overturn prevention device. 1 shows a front view of FIG. This furniture fall prevention tool 1 is assumed to be used in a situation where the distance between the upper surface of the furniture and the ceiling surface is 24 cm or less, and the lifting mechanism using the bolt-shaped member 60 and the storage chamber 20. In addition, even when the gap above the furniture is narrow, an excellent fall prevention function and storage function are exhibited.

  In such a furniture overturn prevention device 1, side plates 4 a and 4 b having substantially the same front-rear width as the bottom plate 2 stand on the left and right ends of the bottom plate 2 formed to have substantially the same size as the left-right width and front-rear width of the upper surface of the furniture. 2 (see FIG. 2), a horizontally long installation plate 5 is installed so as to pass the left and right sides of the side plates 4a and 4b at a predetermined height position, and insertion holes 51 are provided at both left and right side portions thereof. , 51 are drilled in the vertical direction.

  Bolt-shaped members (stud bolts) 60, 60 are disposed through the insertion holes 51, 51 up and down, and are approximately the same length as the installation plate 5 via cup-shaped metal fittings at both upper ends thereof. The nut-like members 61, 61 that support the contact plate 6 and are screwed in the middle of the bolt-like members 60, 60 are placed on the upper surface of the installation plate 5, and the nut-like members 61, 61 are arranged. The contact plate is moved up and down by turning a tool with a tool such as a spanner, and these constitute an elevating mechanism for the contact plate 6.

  In the present embodiment, a horizontally long door plate 3 made of a single plate is hinged on the lower end side so as to close the opening end on the front side of the portion surrounded by the side plates 4a and 4b and the bottom plate 2, and the door is opened and closed. Is configured. The inner portion formed by the side plates 4a and 4b and the door plate 3 serves as a storage chamber 20 for storing articles, but the upper end side thereof is opened without being blocked by the top plate, so the storage chamber 20 The storage space is substantially expanded to the lower surface of the ceiling 100. The door plate 3 described above may be a single plate if the lateral width is up to about 80 cm, but if it is larger than this, the door plate can be opened and closed independently by dividing it into two or more in the longitudinal direction. If you do, it will be more convenient.

  Further, the door plate 3 constituting the open / close door is configured such that the lower end of the door plate 3 is screwed to the portion near the opening end of the bottom plate 2 with hinge members 7 and 7 so as to open downward to the horizontal position. Thus, the point that it is a lower opening type opening / closing door is a characteristic part in the present invention. In other words, when the storage box type furniture fall prevention tool is arranged, if the gap between the furniture and the ceiling is wide to some extent, the door opening type that opens the door to the left or right or the top opening type that is hinged to the top plate may be used. However, when the gap above the furniture is extremely narrow as in the present embodiment, problems arise in terms of the arrangement of the hinge members and the operability of the lifting mechanism, etc., and it is difficult to adopt the method. It is an openable door.

  Thereby, the storage chamber 20 is configured such that the top plate is unnecessary and the upper side is open, and the door plate 3 is configured to open until the inner side surface thereof is substantially flush with the upper surface of the bottom plate 2. Since the vertical width of the opening end becomes a large one that substantially coincides with the distance from the upper surface of the bottom plate 2 to the lower surface of the ceiling 100, the entrance of the storage chamber 20 can be used more widely and the storage chamber 20 can be easily stored. The elevating mechanism disposed on the back side can also be easily operated.

  In the present embodiment, since the storage chamber 20 has no top plate, almost all of the upper end side is opened, but at least the center of the storage chamber 20 in the front-rear direction is provided. If it is opened, even if it has a top plate on its back side, it can exert the same effect as described above, and if it is opened more than two-thirds in the front-rear direction, it has a sufficient storage capacity. It can be demonstrated. Further, as shown in FIG. 1, the bottom plate 2 is preferably fixed to the upper surface of the furniture by a fixing means such as a joint bolt 8 from the viewpoint of ensuring earthquake resistance.

  FIG. 3 shows a state in which the door plate 3 of the furniture overturn prevention device 1 is closed. In the present embodiment, the door can be locked in this closed position. That is, referring to FIG. 1 again, a hook-like locking member 32 is disposed near the opening end of the inner surface of the side plate 4a, and engages with the locking member 32 at the position of the inner surface of the door plate 3 corresponding thereto. A lock member 31 having a protrusion is provided, and these constitute a lock mechanism.

  In this locking mechanism, the knob-like operation button 33 that penetrates the door plate 3 from the locking member 31 and protrudes to the front surface side is pressed with a finger to the pushing position, thereby protruding sideways from the locking member 31 and being locked. A projection (not shown) that is locked to the member 32 is fixed to maintain (lock) the closed state of the door plate 3, and when the operation button 33 is pushed again, it returns to the protruding position and the closed state is maintained. It is to be released.

  Thus, by operating the operation button 33 and keeping the door in the locked state, it is possible to avoid a situation in which the door opens unexpectedly and an article in the storage chamber 20 falls in the event of an earthquake. Further, since the operation button 33 can be used as a knob that is manually picked when the door is opened and closed in the protruding state with the unlocked state, the lock operation / unlock operation can be performed simultaneously with the opening / closing operation of the door plate 3.

  Referring to FIG. 4, the furniture overturn prevention device 1 described above exhibits the seismic resistance function by bringing the contact plate 6 close to or in contact with and pressing the ceiling 100 by performing the above-described lifting operation. However, the height adjustment operation of the contact plate 6 is performed by rotating a nut-like member 61 screwed to the bolt-like member 60. In this embodiment, the upper surface of the construction plate 5 near the left and right ends. A system is employed in which work is performed by manually rotating two bolt-shaped members 60 mounted on the side.

  That is, as shown in the longitudinal sectional view during the adjustment operation in FIG. 5, the furniture overturn prevention tool 1 with the contact plate 6 in the lowered position is placed on the upper surface of the cupboard 200, and the door plate 3 is opened to the horizontal position. In this state, a hand is inserted into the storage chamber 20 from the open end, and the left and right nut-like members 61, 61 are turned using a tool such as a spanner 90, and the abutting plate 6 is suspended from the ceiling while raising both bolt-like members 60. The adjustment operation is performed by approaching or abutting / pressing 100.

  On the other hand, when removing the furniture overturn prevention tool 1 of the present embodiment, the abutting plate 6 may be lowered by carrying out the reverse procedure to the above, but in any operation, the nut-like members 61 and 61 are attached. Since the operation is simply a turning operation and does not require specialized technology, anyone can easily perform the attaching / detaching operation and can complete the mounting operation in a short time. Further, the furniture overturn prevention device 1 according to the present invention is configured to be substantially flush with both side surfaces and the front surface of the furniture on which the furniture is to be placed, and thus has substantially the same appearance as the filler type overturn prevention device described above. It is excellent in terms of appearance.

  In the present invention, the minimum size of the gap between the furniture to be installed and the ceiling is assumed to be 10 cm. In other words, it is preferable to place a dowel for positioning on the upper surface side of the furniture. If the minimum vertical width according to the present invention is about 8 cm into which a hand can be inserted, in addition to this width, the dowel is attached to the above-described dowel. This is because a margin of about 2 cm is required for the work.

  In the present embodiment described above, the pair of hinge members 7 and 7 that hinge the door plate 3 to the bottom plate 2 incorporates a spring and biases the door plate 3 in the closing direction near the closed position. In addition, the door plate 3 has a function of opening the door plate 3 to a substantially flush state with respect to the upper surface of the bottom plate 2. In addition to this function, a damper function for slowly urging in the closing direction may be provided. .

  As described above, the furniture overturn prevention device that is interposed between the furniture and the ceiling and exhibits the fall prevention function and the storage function, according to the present invention, even if the gap above the furniture is narrow, it looks good. It can now be installed easily without compromising.
