Relates to a disaster prevention device using.

  Earthquake countermeasures for buildings have evolved remarkably in recent years, and various seismic technologies such as reinforcement structures for columns and walls are known, but on the other hand, earthquake countermeasures for existing houses, especially wooden houses, have been constructed. There are many conditions to consider, such as deterioration of the object itself, changes in the ground and neighboring environments, changes in equipment loads, etc. Even if it is known that earthquake countermeasures are necessary, seismic retrofitting should be performed for the above conditions and cost reasons. There are times when you can't.

  Houses without earthquake countermeasures may cause serious harm to residents such as tableware, books, or ceiling boards that fall from the overhead.Furthermore, wooden houses that have not been reinforced against earthquakes are at risk of collapse. It is also high, and there is the actual situation that a great deal of damage occurred when a large earthquake occurred.

  It is well known that people are evacuated by hiding in sturdy furniture such as desks in the event of an earthquake, but it is difficult to make an instant and calm decision, and furniture that can be evacuated when sleeping. Is assumed not to be familiar.

  On the other hand, for example, a personal protective device attached so as to cover a bed and the like as disclosed in JP-A-8-322965 (Patent Document 1) and JP-A-2010-43516 (Patent Document 2). Is also known, and an earthquake-resistant shelter of a size that covers the entire room as disclosed in Japanese Patent Laid-Open No. 2003-328584 (Patent Document 3) is also known.

  However, these devices are simpler and cheaper than earthquake-proof reinforcement of the building itself and can take measures against earthquakes, but with these devices installed indoors, inconvenience and pressure can be felt in daily life. You have to be patient, and if the size of the room is large enough, the problem of load bearing of the building and the cost burden will be heavy.

  Therefore, for example, an airbag-type disaster prevention device that is activated by detecting an earthquake as disclosed in JP 2010-121385 A (Patent Document 4) is known.

  According to the invention presented in Patent Document 4, the occupant is housed in a contracted state in normal time, and the airbag is inflated when the earthquake is detected and the gas is ejected, so that the occupant is accommodated and is surely prevented from falling objects. It is said that it can be protected.

  However, such an expansion type disaster prevention device cannot expand at a sufficient speed or malfunction due to deterioration of stored gas or container or change of ejection amount or ejection speed depending on temperature. May occur, and the purpose of protecting residents from falling objects may not be achieved. Further, there is a problem that it is difficult to store it again after expansion and reuse it.

  Therefore, the present invention has been made as an improved invention based on the mechanism of the combined operation coupling device (Japanese Patent Laid-Open No. 9-242444 (Patent Document 5)) previously disclosed by the inventor of the present application.

Fixing holes 6 are formed in the vicinity of the elongated holes 5, and the elongated holes 5 are formed in the lower panel 1b at positions facing the fixing holes 6, and the elongated holes 5 are sequentially and repeatedly formed in each panel 1. Thus, all the panels 1 of the panel unit 101 are slidably connected.

  Further, the long hole 5 that constitutes the connecting structure 20 is formed by a narrow narrow hole portion 51 that is open to the facing surface side of the one panel 1 and the narrow narrow hole portion 51 that is connected to the narrow narrow hole portion 51 in the thickness direction. It also has a wide wide hole portion 52 and a step portion 54 formed on the inner peripheral surface 53 of the long hole 5, and is formed as a two-step long hole.

  On the other hand, the fixing hole 6 that constitutes the connecting structure 20 is wider than the small diameter hole portion 61 that is opened to the facing surface side of the other panel and the small diameter hole portion 61 that is continuously provided in the thickness direction of the small diameter hole portion 61. A large-diameter hole portion 62 is formed, and a step portion 64 formed on the inner peripheral surface 63 of the fixing hole 6 forms a small-diameter hole portion 61 and a large-diameter hole portion 62, forming a round hole having two steps. .

  The width W1 of the narrow narrow hole portion 51 of the long hole 5 and the width of the small diameter hole portion 61 of the fixed hole 6 are formed to be substantially the same.

  In addition, as shown in FIG. 9, the connector 7 that constitutes the connecting structure 20 includes the short side S and the short side S that can be fitted into the narrow long hole portion 51 of the long hole 5 formed in the panel 3. A cross-section I having a columnar shaft portion 71 having a wide side L formed to be wide and large-diameter disk-shaped heads 72 and 72 that can be accommodated in the wide elongated hole portion 52 at both ends of the shaft portion 71. It is shaped like a letter.

  Further, the shaft portion 71 of the connector 7 includes a central shaft 73 having a substantially oval cross section, and a pair of locking protrusions 74 and 74 formed so as to project axially from the central shaft 73. A tool engaging groove 75 is formed on the surface of the head 72.

  In order to mount the connecting tool 7 constituting the connecting structure 20 in the fixing hole 6 and the long hole 5, one head 72 is removed from the shaft portion 71 and the shaft portion 71 is inserted into the fixing hole 6 and the long hole 5. Then, the removed head portion 72 is attached and mounted again. In the connector 7 in the present embodiment, as shown in the exploded perspective view of FIG. 10, one head portion 72 and the shaft portion 71 are integrally formed. The component 7a, the component 7b that is the other head 72, and the fixing screw 75 that fixes the components in a fitted state.

  It should be noted that male and female screws may be provided on the components 7a and 7b without using the fixing screw 75, or may have another structure such as a snap-fit structure utilizing elastic force (not shown).

  Then, the shaft portion 71 of the connector 7 is fitted into the narrow narrow hole portion 51 of the pair of long holes 5 and the small diameter hole portion 61 of the fixing hole 6 which are communicated between the facing surfaces of the facing panels, and the shaft portion 71 is also inserted. The heads 72 on both ends of the panel are fitted into the wide long hole portions 52 of the pair of long holes 5 and the large diameter hole portion 62 of the fixing hole 6 so that the opposing panels 1 and 1 slide in one direction by a predetermined distance. Connected as possible.

  As described above, the panel unit 101 according to the present embodiment includes the elongated hole 5 formed in one panel 1 and extending in the sliding direction, the fixing hole 6 formed in the opposite position of the other panel 1, and the connector 7. The connecting structure 20 allows the panels 1 overlapping each other to easily and reliably slide in parallel in the lateral direction and extend.

  Further, the connecting structure 20 in the panel unit 101 of the present embodiment has a lock mechanism 70 that locks the extended state in a releasable state in a slidable state.

  As shown in FIG. 11, the lock mechanism 70 according to the present embodiment has a narrow hole portion having a width W1 or more at the end of the elongated hole 5 formed in the panel 1 in the sliding direction of the panel and having the wide elongated hole portion. The rotating part 55 is formed to have a width W3 that is equal to or smaller than the width W2, and a pair of locking protrusions 74 and 74 that are formed to project from the shaft part 71 of the connecting tool 7. After the sliding state shown in FIG. 11A passing through the narrow and long hole portion 51 of the hole 5, the panel 1 is further slid, and the sliding shown in FIG. 11B is almost finished. . Then, at this time, since the inclined guide surface 551 is formed at the rear end of the rotating portion 55, the locking projection 74 of the connector 7 contacts the guide surface 551, and the locking projection 74 is tilted. The connector 7 is rotated by being guided.

  FIG. 11C is a diagram showing a state in which the lock mechanism 70 is activated by the rotation of the connector 7 of the panel 1 that has finished sliding. At this time, since the locking step 552 is formed on the side opposite to the inner end of the rotating portion 55, the locking projections 74, 74 of the connecting tool 7 abut the locking step 552 of the elongated hole 5. As a result, the panel 3 which has completed the slide is held in the extended state.

  In this embodiment, the connector 7 in which the locking projections 74, 74 are formed at the opposite positions of the central shaft 73 having a substantially oval cross section is used. However, like the connector 7A shown in FIG. The shaft 73A may have a cylindrical shape, and like the connector 7B shown in FIG. 13, the entire shaft portion 71B serves as the central shaft 73B having a substantially oval cross section, and the length from the long side L to the short side S. The remaining portion after subtracting may be used as the locking protrusion 74B. In addition, when the entire shaft part is composed of an oval or oval shape having a short side and a long side in a cross-sectional view, or an oval or rectangular center axis, the width of the narrow hole is narrower than that of the small diameter hole. (Not shown).

  Further, in the present embodiment, when it is desired to release the lock after locking the holding state by sequentially extending the plurality of panels 1, in the tool engagement groove 75 formed on the surface of the head 72 of the connecting tool 7. This is a simple structure that can be unlocked by engaging and rotating an appropriate tool or the like and returning the inside of the narrow narrow hole portion 51 of the long hole 5 to the longitudinal direction through which the shaft portion 71 of the connector 7 can pass.

  FIG. 14 shows a different embodiment of a disaster prevention panel unit with a lock mechanism used in the present invention. In the panel unit 102 of the present embodiment, the panel units 102 facing each other extend in parallel to the sliding direction. A guide ridge 17 and a guide groove 17 into which the guide ridge 17 is fitted and slid are formed.

  In this way, the guide protrusion 17 is inserted into the guide groove 18 and slides, thereby preventing the rattling of the panel slide and stabilizing the direction of extension particularly in the left-right direction, and each panel of the panel unit 102. It was possible to reliably extend 1 in the desired direction.

  FIG. 16 shows an example of how to use the disaster prevention panel unit with a lock mechanism. In the panel unit 103 of the present embodiment, the return string 81 is attached to the attachment portion 14 formed in the frontmost panel 12 located at the tip. One end 82 of the return string 81 is fastened and the other end 83 of the return string 81 is suspended via the case body 3.

  By fixing the return cord 81 to the frontmost panel 12 as described above, when the panel unit 103 in the locked state after use is returned to the original state, the operator simply pulls the return cord 81 with one hand. Since 1 is urged in the direction of returning to the overlapping state in the normal state (opposite to the sliding direction), the lock can be released by rotating each connecting tool 7 with one free hand, which is excellent in workability.

  FIG. 18 shows an example of how to use the disaster prevention panel unit with a lock mechanism. In the panel unit 104 of the present embodiment, one end 86 of the waterproof cover is fixed to the fixed panel 11 and located at the tip. The other end 87 of the waterproof cover 85 is fixed to the frontmost panel 12.

  The width of the waterproof cover 85 is approximately the same as the long side direction of the panel 1, and the length of the waterproof cover 85 is approximately the same as the total length of the panel 1 in the expanded state. The waterproof cover 85 is held in a folded state inside the case body 3 when the panel unit 104 is in a housed state.

  By fixing the other end 87 of the waterproof cover 85 to the front panel 12, when the panel 1 is extended, the waterproof cover 85 pulled and developed by the front panel 12 is in an extended state. By covering the entire top surface, it is possible to protect the space under the panel 1 from wind and rain.

  When the panel unit 104 is used inside a building, the inside of the panel 1 is not wetted even if the building is damaged and rain leaks occur. When used outside the building, typhoons, floods, etc. The momentum can be shut off, and in each case, a safe space below the panel can be secured.

  In addition, without fixing the other end 87 of the waterproof cover 85 to the frontmost panel 12, a plurality of panels are continuously extended by vibration of an earthquake, for example, and then the cover body 3 is folded or rolled to be waterproof. The cover 85 may be pulled out with a string or the like to cover the extended panel 1 (not shown).

  It is desirable that the waterproof cover 85 in the present embodiment has such strength that it is not easily damaged by the impact of a falling object or the like and has a density that does not easily allow water to pass through. For example, any material such as a sheet-shaped synthetic resin is selected. Can be used.

  Next, with reference to FIGS. 20 to 26, a disaster prevention device 201 using the disaster prevention panel unit with a lock mechanism according to the present invention will be described.

  The disaster prevention device 201 in the present embodiment is used by being fixed to a building B having inner walls W facing each other and fixed to a ceiling C of the building B so as to extend toward the inner walls W on both sides, and in normal times. It is composed of a plurality of rectangular panels 1 in a plan view in an overlapping state, and a connecting structure 20 that slidably connects the panels 1 and 1 in contact with each other toward the lower side, which is the ground or floor, and further the connection. The structure 20 has an upper surface 34 provided with a plurality of mounting holes 37 for fixing the panel unit 101 having the lock mechanism 70 to the ceiling C of the building B having the facing inner wall W, and the lighting function. And a pair of side surfaces 36, 36 connecting the upper surface 34 and the lower surface 35 to each other. A total of four sets of panel units 101 arranged vertically in two stages and horizontally are housed in the formed case body 3, and a mounting screw 39 is provided through a mounting hole 37 provided in the upper surface 34 of the case body 3. Thus, the building B is fixed to the ceiling C near the center inside the building B so as to extend toward the inner walls W on both sides and used.

  In addition, in the present embodiment, the light emitting portion 35 having an illumination function is integrally provided on the lower surface 35 of the case body 3, so that the power source is secured by connecting to the electric wiring provided in the building, and the case body 3 is connected. Can be used as lighting in the room where

  When an earthquake occurs, the stopper 42 is disengaged due to the vibration, and the locking tool 4 is rotated around the hinge portion 41 to be in an open state, and the panel 1 slides out of the case body 3 through the openings 31 and 31 and slides. The panel 1 which started the process is extended in the sliding direction one after another.

  At this time, since the panel 1 is installed at a position where it extends toward the inner walls W on both sides, and the total length when the panel 1 completes the extension is set to be longer than that in contact with the inner wall W, The frontmost panel 12 bends after its tip comes into contact with the inner wall W, and further extends while sliding down, and after sliding down to the lower end of the inner wall W, the panel 1 terminates sliding and the lock mechanism 70 operates. Then, the return of the slide is restricted and the extended state is maintained.

  21, 22, and 23 are views showing a state in which the panel 1 is extended and fully spread between the opposing inner walls W, and the plurality of panels 1 thus extended are semicircular arch-shaped between the inner walls W. Will be held locked to each other.
