  The present invention relates to a furniture overturn prevention device, and more particularly, to a furniture overturn prevention device that prevents the furniture from overturning in the event of an earthquake using a strut pole that is laid in a vertical direction by pressing a pressing plate against a ceiling.

  As a means for preventing furniture such as cabinets and chests from falling in the event of an earthquake, as described in Japanese Utility Model Publication No. 3019242 and Japanese Patent Application Laid-Open No. 8-322666, the upper and lower ends of the tension pole 2. Description of the Related Art A furniture overturn prevention device is known that has a push plate on the side and is constructed between a top surface and a ceiling surface of furniture to prevent the overturn.

  These furniture fall prevention devices use a pipe-type turnbuckle or a telescopic screw mechanism with a combination of female screw holes and male screw shafts, allowing the length to be adjusted in the vertical direction. It is possible to adjust to the difference in the distance (distance) between the two, and by constructing the pressing plate so as to press the upper surface and the ceiling surface of the furniture, the function of preventing the furniture from falling is exhibited.

  However, furniture fall prevention devices with such functions are placed directly upright on the top surface of the furniture, so the furniture will be displaced forward due to thin furniture in the front-rear direction or the shaking of the earthquake. When it moves, there is a concern that it will be relatively easily bent together with the furniture in a side-viewed “<” shape and fall off the furniture.

  In addition, in the case of tall furniture, it is necessary to secure a foothold when installing it, and it is easy to work, and there are cases where it can not be installed if the clearance between the top surface of the furniture and the ceiling surface is small Many. Furthermore, in the case of furniture that is stacked and thin in the front-rear direction, even if the appliance is arranged on the upper surface, the overlapping portion may protrude forward and fall down in a folding manner due to the shaking of the earthquake.

  An object of the present invention is to solve the above-described problems, and it is an object of the present invention to make it possible to reliably prevent a fall due to an earthquake in any form of furniture.

  Therefore, the present invention is arranged by laying on the left and right sides of the furniture in a state where the pressing plates having the tension poles arranged at the upper end and the lower end thereof are pressed against the floor surface and the ceiling surface, Each has a swing restricting means having an abutting portion that abuts at least a predetermined position on the front surface of the furniture at an intermediate position in the vertical direction. By abutting, at least the forward swing range is limited, and a fall prevention function is exhibited.

In this way, the tension poles constituting the furniture overturn prevention device are arranged on the left and right sides of the furniture in a manner of being laid between the floor surface and the ceiling surface, and the swing limiting means provided in the middle position thereof By limiting the range in which the furniture can swing forward, it can be placed even when the gap between the top surface of the furniture and the ceiling surface is narrow. Even if it exists, the rocking | fluctuation range can be restrict | limited and a fall can be prevented reliably.

  Further, in this furniture overturn prevention device, the swing restricting means is a connecting bar that is horizontally installed between the pair of extension poles and connects the extension poles in the horizontal direction. In addition to being able to reliably limit the swing range to the front, the two strut poles are integrally connected, so that the structure is excellent in strength.

  Further, in this furniture overturn prevention device, the connecting bars are inserted into the projecting poles, can be slid up and down on the outer peripheral surface, and can be locked at an arbitrary height on both ends. When it is assumed that the connecting bar is connected to the tension pole, it is easy to arrange the connecting bar at a height position avoiding the opening / closing portion of the furniture. In this case, the connecting tool is a bar-shaped bar connection that extends in the centrifugal direction from the outer peripheral surface of the annular portion that is inserted and locked by the tension pole so that the end of the connecting bar can be removably connected from above. Even if the connecting bar is arranged at a height position that matches the furniture opening / closing part, the bar connecting part can be rotated in the circumferential direction of the tension pole with the connecting bar removed. It can be in a state that does not interfere with the opening and closing operation.

  Furthermore, in the furniture overturn prevention device using the connection bar as the swing restricting means, the furniture fall over prevention device having the same configuration as that of the furniture overturn prevention device is placed horizontally with another connection bar. In addition to making the entire structure even stronger, the connecting bar that connects furniture overturning prevention devices also has a furniture swing that depends on the direction of the connection. Demonstrate the restriction function for the direction of movement.

  Alternatively, as a swing restricting means, it is a connecting belt that is installed in the horizontal direction between the pair of projecting poles and connects the two projecting poles, and is movable in the vertical direction on the projecting poles. Opening and closing function of furniture while having a buckle for adjusting the length at the midway position of the belt part, and not being able to change the overall length, while easily adapting to various left and right width furniture It can be installed at a position where it does not impair the fall prevention function.

  In addition, in the above-described furniture overturn prevention device, a male screw shaft extending from the upper surface side of the pressing plate is screwed from below into a female screw hole provided in the lower end portion of the cylindrical member at the lower end side of the tension pole. Then, if fine adjustment means is provided to change the overall length of the tension pole within a predetermined range by turning the male screw shaft, the tension pole can be adjusted to an appropriate pressing state without labor. it can.

  Furthermore, in the furniture overturn prevention device described above, the locking means of the projecting pole is a male screw shaft inserted into the outer peripheral surface of the rod-like member on the inner peripheral side by screwing the male screw shaft of the set screw from the outer peripheral side of the cylindrical member. The tip of the rod is pressed to lock the sliding of the rod-shaped member, and the tip of the male screw shaft is pivotally mounted around the screw center axis and is in contact with the outer surface of the rod-shaped member If you have a pressing part that can only be pressed without rotating by the screwing operation of the male screw shaft, the outer peripheral surface of the rod-shaped member can be printed hard to damage by the screwing operation of the set screw In addition, it is difficult for loosening to occur after fixing, and it is easy to ensure a reliable locking state.

  According to the present invention, the tension poles are installed between the floor surface and the ceiling surface to be arranged in pairs on the left and right sides of the furniture, and the range in which the furniture swings at least forward is limited by the swing limiting means. Even furniture can be reliably prevented from falling.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the present invention, the furniture includes office supplies used in offices, etc., in addition to those used in general households such as cabinets and chests.

  FIG. 1 shows a perspective view of a furniture overturn prevention device 1A of the present embodiment. This furniture overturn prevention device 1A is capable of sliding in a vertical direction a rod-like member 12 having a push plate 15a on the upper end side from an upper end opening portion of the cylindrical member 11 having a push plate 15b on the lower end side and opened on the upper end side. A pair of projecting poles 10 are provided which are inserted in a state and can be fixed to an arbitrary total length with set screws 16a and 16a as locking means.

  The pair of projecting poles 10 and 10 have both ends of a connecting bar 13a serving as a swing restricting means having an abutting portion that abuts against a predetermined position on the front surface of the furniture 100 indicated by a one-dot chain line at an intermediate position in the vertical direction. Are connected to the rod-shaped member 12 by the connecting tools 14 and 14 so that they are connected in the horizontal direction to form an H-shaped structure as a whole.

  Further, the tension poles 10 and 10 are installed in the vertical direction while pressing the pressing plates 15a and 15b on the floor surface and the ceiling surface (not shown) at the left and right ends of the furniture 100 to be prevented from falling or slightly forward. The range of the furniture 100 that can be swung forward is limited by contacting the front side end portion of the furniture 100 with the side surface portion of the connecting bar 13a that is arranged in the state and is located in the middle position when the shaking occurs due to the earthquake. The feature of the present invention is that the fall prevention function is exhibited.

  That is, the conventional furniture overturn prevention device is installed between the upper surface of the furniture and the ceiling surface, and exhibits a fall prevention function, so that it cannot be arranged when the distance between the ceiling and the upper surface of the furniture is narrow. In the case of furniture that is stacked and thin back and forth, there is a concern that if the upper surface is simply pressed, it will bend and fall over in the middle position. On the other hand, the furniture overturn prevention device 1A according to the present invention is arranged in pairs on both ends of the furniture in a manner of being laid between the floor surface and the ceiling surface, and swings provided at the midway positions of the tension poles 10, 10. The restricting means abuts on the front side of the furniture 100 to restrict the swing range to the front of the furniture 100. Even in such a case, a reliable fall prevention function can be exhibited.

FIG. 2 is a longitudinal sectional view for explaining the detailed configuration of the furniture overturn prevention device 1A. In the pair of tension poles 10 and 10 constituting the furniture overturn prevention device 1A, the rod-like member 12 inserted into the tubular member 11 has a cylindrical shape whose outer diameter is slightly smaller than the inner diameter of the cylindrical member 11. It is slidable in the vertical direction while being inserted from the upper end side opening of the member 11.

  Then, in a state where the ceiling surface 300 is pressed by the upper end push plate 15a, the nuts 111, 111, 111 provided at the outer surface positions of the screw hole portions drilled at a predetermined interval near the upper end of the cylindrical member 11 are connected to the male members. By pressing the outer peripheral surface of the rod-shaped member 12 at the distal end side of the set screw 16a into which the screw shaft 160 is screwed, the entire length of the rod-shaped member 12 can be locked from the distal end of the cylindrical member 11 and fixed. ing. The three set screws 16a are arranged so as to sandwich the outer peripheral surface of the rod-like member 12 from both the left and right sides, and exhibit a larger fixing force than in the case of only one direction. .

  Further, a male screw shaft 150 extending from the upper surface side of the pressing plate 15b arranged on the floor surface 400 and capable of rotating separately from the pressing plate 15b is provided at the lower end side of each projecting pole 10. It is screwed into the female screw hole of the nut member 112 inserted at the lower end of the tubular member 11 from below, and the male screw shaft 150 is rotated by operating the handle 151 so that the total length of the tension pole 10 is predetermined. An adjuster 17 is provided as a fine adjustment means for changing within a range, and fine adjustment after locking and fixing with a set screw 16a can be easily performed.

  The connecting tools 14 and 14 which connect both ends of the connecting bar 13a to the projecting poles 10 and 10 include an annular portion 14a extending in the vertical direction and a bar-shaped bar connecting portion 14b extending in the centrifugal direction from the outer peripheral surface thereof. The end of the connecting bar 13a is detachably connected from above by the bar connecting portion 14b. The connecting member 14 is inserted into the rod-shaped member 12 and can slide up and down on the outer peripheral surface thereof. However, as shown in the enlarged perspective view of the drawing arrow, it is formed in an annular shape by an elastic resin such as synthetic rubber. The annular portion 14a is placed on the upper surface of the retaining band 140 which is fastened and fixed at an arbitrary height position on the rod-shaped member 12 by the elastic force, thereby being locked at an arbitrary height position on the rod-shaped member 12. It has become so.

  In addition, although the connection bar 13a is arrange | positioned at the rod-shaped member 12 above the opening part of the cylindrical member 11 in a figure, the connection position is not limited to the position, It is above this. Further, the inner diameter of the annular portion 14a may be further expanded to be inserted and connected to the cylindrical member 11 side. Furthermore, a plurality of connecting bars 13a can be arranged in parallel at different heights.

  Next, the other functions of the furniture overturn prevention device 1A will be described. As shown in FIG. 3, the connecting bar 13a is detached from the bar connecting portions 14b of the two connecting devices 14 simply by pulling the connecting bar 13a upward. When the door portion of the door is opened and used, the opening / closing operation can be prevented. In this case, since both the connecting tools 14 are rotatable in the circumferential direction of the rod-shaped member 11, the bar connecting portion 14b protruding in the lateral direction can be set at a position that does not interfere with the furniture opening / closing operation. Further, the set screw 16a can be used as a hook, and it is extremely useful in an emergency when a flashlight 500 is hung or a disaster prevention device such as a helmet is hung as shown in the figure.

  FIG. 4 shows an example of an arrangement method of the furniture fall prevention device 1A described above. A furniture fall prevention device 1A having the same configuration arranged adjacent to the furniture fall prevention device 1A shown in FIG. It is set as the state connected with right angle in the horizontal direction using the connection tools 14 and 14 and the connection bar 13b. In this way, by connecting the two or more furniture fall prevention devices 1A with the connection bar 13b, the strength of the entire structure can be further increased. The connection bar 13a used for the connection is, for example, a clothesline. It can also be used for other purposes, such as using as a bag or hanger hook.

  FIG. 5 shows a furniture overturn prevention device 1B as an application example of the above-described furniture overturn prevention device 1A. Also in this application example, the configuration of the pair of projecting poles 10 and 10 is the same as that described above. However, as described above, the swing restricting means connects the two projecting poles 10 and 10 with the connecting bar 13a in the horizontal direction. Rather than being connected to each other, the independent limiting members 18a, 18b, and 19 are provided at appropriate positions for each of the tension poles 10 to limit the swing range of the furniture 200.

  The restricting member 18a has a contact plate 182 having surfaces that respectively contact the upper surface, the front surface, and the side surface of the corner portion of the furniture 200 having a length lower than that of the furniture 100, and a bar-like shape having a set screw 16a. It is composed of a connecting portion 181 for connecting to the member 12, and a cushion (not shown) is provided on the abutting surface of the abutting plate 182 to prevent the furniture 200 from being damaged, and at a predetermined height position of the rod-shaped member 12. The connecting portion 181 is fixed, and restricts not only the front direction but also the lateral and upward swing ranges of the furniture 200. The restricting member 18b is symmetrical to the restricting member 18a and exhibits the same function as described above.

  On the other hand, the limiting member 19 includes a contact plate 192 having surfaces that respectively contact the front surface and the side surface of the corner portion of the furniture 200, and a connection portion 191 having a set screw 16a to connect to the tubular member 11. The connecting portion 191 is fixed to the cylindrical member 11 with a set screw 16b in a state where the abutting surface provided with a cushion (not shown) is in contact with each surface of the furniture 200. In other words, the swing range in the left-right direction is limited. Then, these restricting members 18a, 18b, 19, and 19 on the two tension poles 10 and 10 arranged at positions that do not protrude forward from the front surface of the furniture 200 and are not disturbed cooperate with each other. By limiting the swing range, the overturn can be reliably prevented.

  FIG. 6 shows a connection bar 13c as a modification of the connection bars 13a and 13b used in the furniture overturn prevention device 1A in FIGS. The connecting bar 13c is formed by inserting rod-shaped expansion / contraction bodies 131 and 132 to a predetermined depth from both ends of the cylindrical main body 130, and a spiral body inside the main body 130 (not shown) and inner peripheral surfaces of the expansion / contraction bodies 131 and 132. By combining the spiral grooves formed in the above, the total length of the stretchable bodies 131 and 132 can be changed by rotating them around the central axis, and at various intervals between the pair of projecting poles 10 and 10. On the other hand, it can be easily handled.

  FIG. 7A shows a connecting belt 13d that can be used in place of the connecting bars 13a, 13b, and 13c described above. The connecting belt 13d is installed between the left and right projecting poles 10 and 10 in the horizontal direction and functions as a swing restricting means, and a cylindrical member 11 or a rod-like member is provided at both ends of the belt-like belt portion 135. 12 have hook-like bodies 136 that can be latched from the side, and the vertical poles 10 and 10 can be moved in the vertical direction so that they can be appropriately positioned away from the opening and closing portions of the target furniture. It can be used in a state where it is difficult to impair the function of the furniture.

  Further, the belt part 135 of the connecting belt 13d has a buckle 138 for adjusting the length in the middle of the connecting belt 13d, and the total length can be changed. Further, the belt part 135 has a one-touch buckle 139 for attachment and detachment. Separation / connection in the middle of 135 can be performed with a single touch, the length can be easily adjusted, and separation can be made in the middle of the belt portion 135 when using furniture, so that it can be kept out of the way.

  FIG. 7B shows an example of the usage state of the connecting belt 13d of FIG. 7A, and this connecting belt 13d has a belt portion 135 that can be bent. It is possible to sufficiently exhibit the fall prevention function of the furniture 100 while connecting the two in a state in which 10, 10 is arranged further rearward than in the case of FIG.
