  However, the prevention of falls with anchor bolts and strings on the veranda has many problems in construction in apartment buildings and rental apartments, and it takes time to remove the cabinet when moving or removing it. It also takes time and money. Moreover, the method of fixing a storage, a cabinet, etc. on a veranda by a tension type is hardly employed from the viewpoint of stability and sustainability.

  On the other hand, for indoor furniture, etc., a technique has been disclosed in which a stretchable column or pole is conventionally attached to the top surface of the furniture, and the area of the vertical contact portion of the column is widened. The effect differs depending on the installation method and installation location, but it is effective for a load or shake in one direction, but is weak for a load or shake from another direction. It may not be possible. The method of attaching the L-shaped metal fitting also has a problem because it is necessary to open a screw hole or the furniture cannot be attached unless the back surface of the furniture is a material that can be screwed. Conventionally, there is a disclosure of a technique related to the expansion and contraction and fine adjustment of a support column, but a technique that enables attachment according to the depth of a cabinet, furniture, or the like is not disclosed.

  The problem we are trying to solve is that it is made up of a plurality of columns, which can be extended and stretched and fixed, and the vertical fixing is made fine by fine adjustment, so that it can handle loads from any direction and cabinet. It is to provide a telescopic fall prevention device that can be mounted in accordance with the depth of furniture and furniture.

  In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that a plurality of strut bodies each composed of an outer strut and an inner strut fitted in the outer strut so as to be vertically extendable and fixable at an arbitrary position, and the strut Upper connection supports that pivot on the upper end of the body so that they can swing in close proximity to each other and come into contact with the downward wall surface or ceiling, etc., and pivot on the lower end of each column to prevent falling A lower support that comes into contact with an upper surface of a furniture or the like that is an object, an elastic body or a fine adjustment device that is provided in at least one of the plurality of support bodies and increases a vertical pressing force, and each support body Is constructed with leg-opening restricting means for opening the leg around the upper connecting support and regulating the leg-opening width. In this way, the lower part is opened centering on the upper end part of the plurality of pillars, the length is expanded and contracted and stretched according to the space between the ceiling etc. and the upper surface part of the furniture, to which load from which direction Also exert drag.

  The invention according to claim 2 is that the support columns are two of the first support column and the second support column, both of the support columns are in the open state with the upper connecting support as the center, and the lower end of the support member is the open leg restricting means. In the fall prevention device connected by the lower support that also serves as a fall prevention device, it is arranged at the left and right ends of the upper surface of furniture or the like that is the fall prevention object. By configuring in this way, the overturn prevention device has a triangular structure and exhibits a resistance against a load in the front-rear and up-down directions, and also exhibits a resistance against a load in the left-right direction by arranging the pair of left and right.

  The invention according to claim 3 regulates the leg width in a state in which the three support columns are the first, second, and third support members, and each support member is opened in a triangular pyramid shape with the upper connecting support as a vertex. The structure is composed of a leg-regulating means. By comprising in this way, the resistance against the load from the up-down, front-back, left-right direction is exhibited with one fall prevention device.

  According to the invention of claim 4, the leg-opening restricting means is a connecting portion that connects the support columns, and the connecting portion expands or contracts, or the connecting position moves up and down without expanding or contracting to open the legs of the support columns. The width is adjusted and regulated. When installing, adjust the length of each strut body and adjust the leg width at the lower end of each strut body with this leg-regulating means to match the size of the furniture, and then fix it further. Avoid legs.

As described above, multiple pillars exert resistance to loads from any direction such as wind and earthquake shaking, and furniture etc. without pulling up and down against vertical vibrations Can prevent falls.
In the fall prevention device composed of two support pillars, a triangular structure is formed by each support pillar and the leg opening restricting means by opening the lower part around the upper end of each support pillar, and this fall prevention By placing the devices on the left and right edges of the upper and lower edges of the furniture in a pair on the left and right and stretching the length to match the distance between the ceiling etc. and the upper surface of the furniture etc., strong resistance against load from any direction can be demonstrated. The fall of furniture etc. by wind can be prevented reliably.

In addition, in the fall prevention device composed of three support columns, the lower part is opened in a triangular pyramid shape with the upper end of each support column as the center, so that the load can be applied to any direction with one fall prevention device. However, it can prevent the fall of furniture and the like due to earthquake and wind by exerting strong drag.
In addition, by adjusting the opening width of each strut body with the open leg restricting means, and restricting it to not open more than the specified angle, it can be installed according to the size of furniture etc. to prevent falling It can be set as the stable fall prevention apparatus.
Furthermore, by closing each column body and making it compact, it is possible to reduce the packing volume, reduce the packing material, and increase the efficiency of distribution.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a telescopic overturn prevention device according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a state in which the fall prevention device 1 of the present invention is installed in a space between a cabinet 7 and a ceiling surface 8. The fall prevention device 1 includes an upper connection support 2 that contacts the ceiling surface 8, a lower support 3 that contacts the upper surface of the cabinet 7, a first support column 41, and a second support column 42.

The first strut body 41 and the second strut body 42 are respectively positioned at the lower ends of the outer struts 411 and 421, the inner struts 412 and 422 inserted into the outer struts so as to be slidable and extendable, and the outer struts 411 and 421. In addition, the first column body 41 includes a fine adjustment device 5 at the lower end portion of the inner column 412. The column columns 41 and 423 are configured to stop the sliding of the inner columns 412 and 422 at arbitrary positions.
The upper connecting support 2 has a substantially U-shaped cross section, and is connected so as to be swingable with the upper ends of the first support column 41 and the second support column 42 being close to each other.

The lower support 3 is also configured to serve as a leg-opening restricting means by pivotally supporting the lower ends of the first support column 41 and the second support column 42 at both ends thereof so as to be swingable.
FIG. 2 is a cross-sectional view of the column fixing part 413 and the fine adjustment device 5 of the first column body 41. The column fixing part 413 is configured to slide and extend the inner column 412 with respect to the outer column 411 in order to make the column body a predetermined length, adjust the length, and then tighten the fixing screw 415 to stop the expansion and contraction of the inner column 412. The column fixing part 423 of the second column 42 also has the same structure. Further, the fine adjustment device 5 is used to stretch a column body having a predetermined length by the column fixing part 413 between a downward wall surface, a ceiling, or the like and an upper surface unit such as furniture.

  Here, the mounting procedure of the embodiment in FIG. 1 will be described in more detail. First, the fixing screws of the column fixing part 413 of the first column body 41 and the column fixing part 423 of the second column body 42 are loosened, and the upper connecting support tool 2, the first support column 41 and the second support column 42 are expanded and contracted to bring the lower support 3 into contact with one side edge of the upper surface of the cabinet 7. The fixing screw of the column fixing part 413 of the one column body 41 is tightened to stop expansion and contraction.

  Next, by rotating the rotating part 52 of the fine adjustment device 5 and moving it upward along the screw of the shaft part 51, the distance between the upper connecting support 2 and the lower support 3 is gradually increased, and the ceiling surface 8. The pressing force to the upper surface of the cabinet 7 is increased, and the upper connection support tool 2 and the lower support tool 3 are temporarily fixed so that they do not move. After temporarily fixing the fall prevention device 1 on one side in this way, the fall prevention device 1 on the other side is also temporarily fixed to the other side edge of the upper surface of the cabinet 7 in the same manner.

  Then, while confirming the left / right balance of the cabinet 7, the fine adjustment device 5 of the left / right fall prevention devices 1, 1 is made to be in a stronger state in the vertical direction. Then, the attachment of the fall prevention device is completed by tightening the fixing screw of the column fixing part 423 of the second column 42 to stop the expansion and contraction.

  In the case of a fall prevention device having an elastic body such as a spring instead of the fine adjustment device 5 (not shown), the length of the support is adjusted to be slightly longer than the distance between the ceiling surface 8 where the support is installed and the upper surface of the cabinet 7. In this state, the slides of the inner and outer columns are fixed and the elastic body is compressed to place it between the ceiling surface 8 and the upper surface of the cabinet 7, and then the elastic body is released from compression and stretched vertically.

  Further, in FIG. 1, the first support column 41 near the back surface of the cabinet 7 is installed vertically and the second support column 42 is fixed in an inclined state in order to simplify the mounting work. It is good also as a shape which can be fixed in the state inclined together as shown by.

  The embodiment of FIG. 4 is basically the same structure as that of FIG. 1, but in the embodiment of FIG. 1, the lower support 3 is configured to also serve as the leg opening restricting means, whereas the embodiment of FIG. In the example, the connecting portion 6 that connects the first and second support columns 41 and 42 is an open leg restricting means. After the first supporting column 41 is fixed by the attaching procedure in FIG. The second support column 42 can be fixed with an open leg width corresponding to the depth. That is, the lower support members 31 and 32 are pivotally supported at the lower ends of the first and second support columns 41 and 42, respectively, and the first and second support members 41 and 42 are moved upward and downward by the connecting portion 6. The structure is such that the leg is opened with 2 as the apex, and the leg width can be adjusted according to the size of the furniture to be prevented from falling.

  As shown in FIGS. 5 and 6, the connecting portion 6 includes cylinders 414 and 424, an outer tube 61, an inner tube 62, a tube fixing screw 416 and a tube fixing screw 63, and the cylinder 414 is connected to the outer tube 61. At one end, a cylindrical body 424 is pivotally supported at one end of the inner tube 62 so that the inner tube 62 can be inserted and slid into the outer tube 61 so that the tube 424 can be expanded and contracted. It can be fixed at an arbitrary position. The cylinders 414 and 424 can move up and down with respect to the outer columns 411 and 421, and the cylinder 414 can be fixed at an arbitrary position by a cylinder fixing screw 416. The tube fixing screw 416 may be structured to be installed at least on one of the first and second support columns 41 and 42, but it is desirable that the entire connecting portion 6 be fixed in a state parallel to the upper connecting support 2. .

  The adjustment of the opening leg width of the column body by the connecting portion 6 will be described with reference to FIG. When narrowing the open leg width, the method of lowering the connection position in the column body without changing the length of the connection part 6 as in (a), and the connection without changing the connection position in the column body as in (b) A method of shortening the length of the portion 6 or a method of combining both is conceivable.
