  According to the proposed disaster prevention bed, it is possible to protect a sleeping person from falling objects and falling objects during an earthquake. However, in order to install such a disaster prevention bed, a large place including the height is required, so that homes and places where it can be installed are limited. When installed in a room, the daily living space is considerably narrowed. Furthermore, when viewed as a furnishing product, it is difficult to say that the appearance is in harmony with the room.

  The present invention has been made in view of such a conventional problem, and an object of the present invention is to protect a sleeping person from a fallen object or a fallen object at the time of an earthquake, and an installation space. Is to provide a disaster prevention bed that is almost the same as a conventional bed and that does not give a strange appearance when viewed as a furniture.

  It is another object of the present invention to provide a disaster prevention bed that can protect not only the human body from an earthquake disaster but also the human body from an intruder.

  According to the present invention, a main body frame constituting a gantry on which a bedding is placed and a head frame for mounting a headboard are provided, and a normal position where part or the whole of the head frame does not interfere with waking up, and sleeping. There is provided a bed for disaster prevention characterized in that the bed can be rotated to a protective position covering at least a part of the body of a person.

  In the event of an earthquake, it is necessary to immediately move a part of the head frame to the protective position, so that the main body frame has a pair of head-side legs, a pair of foot-side legs, a head-side leg, and a foot-side leg. A vertical frame to be installed, a horizontal frame to be installed between the pair of head-side legs and between the pair of foot-side legs, and a vertical column part to which a headboard is attached to the head frame. By installing a handrail between the vertical column and the vertical frame and applying a force to the handrail, the whole or upper part of the head frame is rotated around the attachment portion of the handrail and the vertical frame. It may be.

  Alternatively, the pair of head-side leg portions may be protruded upward from the bed surface, and the lower end portion of the vertical column portion of the head frame may be rotatably connected to the upper end portion of the head-side leg portion. At this time, when a handrail is installed between the head side leg and the vertical frame, and the head frame is rotated to the protective position, the vertical pillar portion of the head frame and the handrail may be in pressure contact with each other. Good.

  Moreover, it is preferable to form an evacuation space in which the person can escape from the standpoint of protecting the human body from a serious situation such as a falling ceiling or a collapsed house caused by a strong earthquake.

  Here, from the viewpoint of protecting the human body from the earthquake disaster and protecting the human body from intruders, a plate-like member is attached to the peripheral side surface of the main body frame so that the evacuation space is sealed and attached to at least one longitudinal side surface. The plate-like member may be freely opened and closed, and may be used as an entrance door to the evacuation space. In this case, it is preferable that the access door can be locked from the inside of the gantry.

  According to the disaster prevention bed of the present invention, in the event of an earthquake, by moving a part or the whole of the head frame from the normal position to the protective position, it is possible to protect the sleeping person from falling objects and falling objects. Further, unlike the conventional case, the disaster prevention bed of the present invention does not require a heavy protective member, so that a large installation space is not required and almost the same installation space as the conventional bed is sufficient, and a large difference in appearance from the conventional bed. There is no discomfort even when viewed as a furniture.

  In addition, the main body frame is provided with a vertical frame constructed between the head side leg portion and the foot side leg portion, and the head frame is provided with a vertical column portion, and a handrail is installed between the vertical frame and the vertical column portion, If force is applied to the handrail so that part or all of the head frame rotates around the attachment part between the handrail and the vertical frame, the head frame is moved from the normal position to the protective position in the event of an earthquake. You will be able to move immediately.

  Even if the pair of head-side legs protrudes upward from the bedding placement surface and the lower end of the vertical column of the head frame is rotatably connected to the upper end of the head-side leg, the same as described above In addition, when an earthquake occurs, the head frame can be immediately moved from the normal position to the protective position. At this time, when a handrail is installed between the head side leg portion and the vertical frame and the head frame is rotated to be in the protective position, the vertical pillar portion of the head frame and the handrail are in pressure contact with each other. It will be able to withstand strong impacts from falling objects and falling objects.

  If a space for evacuation is formed inside the gantry, it is possible to protect the human body from serious situations such as falling ceilings and collapsed houses caused by a strong earthquake. Further, when a plate-like member is attached to the peripheral side surface of the main body frame to make the evacuation space hermetically sealed, and the plate-like member attached to at least one of the long side surfaces can be opened and closed to be an entrance door to the evacuation space. When a thief or the like enters the room, it can escape into the evacuation space inside the gantry and protect the human body from intruders. At this time, if the access door can be locked from the inside of the gantry, the person can be more securely protected from the intruder.

  Hereinafter, the fall prevention device of the present invention will be described with reference to the drawings. The present invention is not limited to these embodiments.

  FIG. 1 is a perspective view showing an embodiment of a disaster prevention bed according to the present invention. The disaster prevention bed in this figure includes a main body frame 1 that constitutes a frame on which the bedding is placed, and a head frame 2 for mounting a head board 51 (shown in FIG. 4). The main body frame 1 includes a pair of head-side leg portions 11a and 11b, a pair of foot-side leg portions 12a and 12b, and a vertical frame that is installed between the head-side leg portions 11a and 11b and the foot-side leg portions 12a and 12b. A frame 13a, 13b, a horizontal frame 14a laid between the head-side legs 11a, 11b, and a horizontal frame 14b laid between the foot-side legs 12a, 12b. A plurality of horizontal rails 15 are installed between them for reinforcement.

  On the other hand, the head frame 2 is formed by integrally forming vertical column portions 21a and 21b and a horizontal column portion 22 connecting the upper ends thereof. Specifically, a metal tube is bent and formed into an inverted U shape. Of course, the shape of the head frame 2 is not limited to this, and various shapes can be adopted as long as the head board 51 (shown in FIG. 4) can be attached (for example, the shapes of FIGS. 5 to 8). The headboard 51 (shown in FIG. 4) may be made of a conventionally known material such as metal, plastic, or wood, and the shape of the headboard 51 prevents the pillow from falling and protects the body from falling objects. If there is no particular limitation.

  Between the vertical column portions 21 a and 21 b of the head frame 2 and the vertical frames 13 a and 13 b of the frame body 1, substantially L-shaped handrails 3 a and 3 b are attached. In addition, one end of the handrails 3a and 3b is fixed to the vertical column portions 21a and 21b, and the other end is pivotally attached to the vertical frames 13a and 13b by the rotation shaft 41.

  In the disaster prevention bed having such a configuration, when an earthquake occurs while sleeping, a force is applied to the handrails 3a and 3b in the direction in which the head frame 1 is rotated (arrow in the figure). Then, the head frame 2 rotates to the protection position above the main body frame 1 together with the handrails 3 a and 3 b around the rotation shaft 41. The figure at this time is shown in FIG.

  As understood from FIG. 2, when the head frame 2 is in the protective position, the head and chest of a person sleeping on the bed are covered with the head frame 2 and protected from falling objects and falling objects. Of course, since the head board 51 (shown in FIG. 4) is attached to the vertical column portions 21a and 21b of the head frame 2, an object that falls between the vertical column portions 21a and 21b of the head frame 2 can also be There is no direct contact with the head. Naturally, the area covered by the head frame 22, that is, the area protected by the head frame 2, becomes wider as the vertical column portions 21a and 21b of the head frame 2 become longer, but the protection position becomes longer as the vertical column portions 21a and 21b become longer. Therefore, the lengths of the vertical column portions 21a and 21b are preferably determined appropriately in consideration of the material of the head frame 2 and the like.

  When the earthquake stops, a force is applied to the handrail 3 or the head frame 2 in the opposite direction to return the head frame 2 to the normal position. In this embodiment, the head frame 2 is manually rotated. However, the head frame 2 may be rotated by providing a drive source. Further, an earthquake detector may be further provided, and the head frame 2 may be automatically rotated to the protection position when an earthquake occurs.

  Further, it is preferable to provide a fixing means for preventing the head frame 2 from rotating so that the head frame 2 does not rotate due to an impact caused by a fallen object or a falling object when the head frame 2 is set to the protective position. An example of the fixing means is shown in FIG. FIG. 3 is an enlarged view of a portion where the handrail 3b is rotatably attached to the vertical frame 13b by the rotation shaft 41. FIG. A lock substrate 71 is fixed to the end of the handrail 3b substantially perpendicularly to the handrail 3b. An arc-shaped notch 711 is formed on the lower side of the lock substrate 71, and a lock arm 72 is swingably attached to the back side of the lock substrate 71 with a pin 73. The lock arm 72 is formed with a lock cutout portion 721 and a grip portion 722 cut out from below. On the other hand, a lock pin 74 is attached to the vertical frame 13b at a position where it engages with the cutout portion 711 of the lock substrate 71 when the handrail 3b rotates about 90 degrees counterclockwise about the rotation shaft 41. It has been.

  In the fixing means having such a configuration, when the head frame 2 (shown in FIG. 1) is in the normal position, that is, in the state shown in FIG. 3A, the lower surface of the grip portion 722 is locked to the lock pin 74 by its own weight. Is in contact with. When the head frame 2 rotates from the normal position to the protective position, the grip portion 722 slides on the lock pin 74 and the lock arm 72 rotates counterclockwise around the pin 73. When the head frame 2 is in the protective position, that is, when the handrail 3b is rotated 90 degrees counterclockwise (FIG. 3B), the lock notch 721 of the lock arm 72 is brought into contact with the lock pin 74. Stuff. As a result, the handrail 3b is prevented from rotating, and the head frame 2 is fixed at the protective position. At this time, the notch 711 of the lock substrate 71 is also engaged with the lock pin 74. Thereby, the force applied to the head frame 2 can be received by the lock pin 74 together with the rotary shaft 41, and the impact resistance of the disaster prevention bed is improved.

  When the head frame 2 is moved from the protective position to the normal position, the grip 722 of the lock arm 72 is lifted upward in FIG. 3B, and the engagement between the lock notch 721 and the lock pin 74 is released. To do. Then, the head frame 2 or the handrail 3 is rotated to the normal position.

  As described above, the bed for disaster prevention of the present invention protects the sleeping person from falling objects and falling objects in the event of an earthquake, but from a serious situation such as falling ceilings and collapsed houses caused by a strong earthquake. In order to protect the human body, it is preferable to form an evacuation space 10 (shown in FIG. 1) in which the person can evacuate inside the main body frame 1. Furthermore, it is preferable that the evacuation space can be sealed so that a thief or the like can enter the room to protect a person from an intruder. An example of such a bed for disaster prevention is shown in FIG.

  In the disaster prevention bed of FIG. 4, a head board 51 is attached so as to block the entire inside of the head frame 2, and a floor plate 50 is placed on the main body frame 1. A bedding (not shown) is placed on the floor plate 50 during actual use. Side plates 52a and 52b are attached to the long side surface of the main body frame 1 so as to be swingable about the upper side, and storage boxes 53a and 53b are swingable about the lower side to the short side surface of the main body frame 1. It is attached. Of course, it is sufficient that at least one of the side plates 52a and 52b can swing, and a side plate may be attached instead of the storage boxes 53a and 53b in the same manner as the long side surface. Note that the storage boxes 53a and 53b in FIG. 4 also serve as plate-like members that seal the evacuation space 10.

  In the disaster prevention bed having such a configuration, when evacuating to the evacuation space 10, one side plate 52 b is opened to enter the evacuation space 10. Then, if necessary, the side plate 52b is locked so as not to open by locking means (not shown) attached to the side plate 52b. This protects you from unexpected intruders. In addition, it is recommended that the head-side leg portions 11a and 11b and the leg-side leg portions 12a and 12b can be expanded and contracted in the vertical direction so that the necessary evacuation space 10 can be secured according to the user's body. Examples of the structure that allows the legs 11 and 12 to extend and contract include a structure in which the inner cylinder is movably fitted into the outer cylinder and fixed at a predetermined position. Of course, it is not limited to such a structure, and a conventionally known structure can be adopted. In addition, a bottom plate that forms the bottom surface of the evacuation space 10 may be attached to the main body frame 1 in preparation for a case where the floor surface on which the disaster prevention bed is placed is not sufficient. Specifically, in FIG. 4, a bottom plate having substantially the same shape as the floor plate 50 is attached to the lower surfaces of the head-side leg portions 11a and 11b and the foot-side leg portions 12a and 12b.

  On the other hand, the storage boxes 53a and 53b store tools and goods necessary when evacuating to the evacuation space 10. Specifically, food and water for several days, jack, flashlight, whistle for notification. As shown in FIG. 4, the storage boxes 53a and 53b swing around the lower side, and the opening 531 opens and closes. Therefore, the tools and articles can be stored in the storage boxes 53a and 53b from the outside. At the same time, since the opening 531 of the storage boxes 53a and 53b has a shape facing the evacuation space 10, the tools and items in the storage boxes 53a and 53b can be freely put in and out of the evacuation space 10.

  In addition, although not shown in FIG. 4, it is desirable to attach a commercial power outlet or a lighting fixture to the evacuation space 10.

  5 and 6 show a second embodiment of the disaster prevention bed according to the present invention. FIG. 5 is a diagram when the head frame 2 is in the normal position, and FIG. 6 is a diagram when the head frame 2 is in the protective position. In the bed for disaster prevention of FIG. 5, the vertical columnar portions 21a and 21b of the head frame 2 stand upright on the head-side leg portions 11a and 11b, and look like one leg in appearance. As in the embodiment of FIG. 1, handrails 3a and 3b are attached between the vertical column portions 21a and 21b of the head frame 2 and the vertical frames 13a and 13b of the main body frame 1, and the handrails 3a and 3b are attached to the handrails 3a and 3b. By applying a force, the handrails 3a and 3b and the head frame 2 rotate in the direction of the arrow in the drawing around the rotation shaft 41 to be in the protection position shown in FIG.

  According to such a configuration, compared to the embodiment of FIG. 1, the space outside the head side required when the head frame 2 rotates is narrow, and the substantial installation space of the disaster prevention bed can be reduced. It can be about the same as a conventional bed.

  7 and 8 show a third embodiment of the disaster prevention bed according to the present invention. FIG. 7 is a diagram when the head frame 2 is in the normal position, and FIG. 8 is a diagram when the head frame 2 is in the protective position. In the disaster prevention bed of FIG. 7, the head-side legs 11a and 11b protrude above the bedding placement surface of the main body frame 1, and the vertical pillars of the head frame 2 extend to the upper ends of the protruding head-side legs 11a and 11b. The lower end portions of the portions 21a and 21b are rotatably connected by a rotation shaft 42. Handrails 3 a and 3 b are attached between the upper portions of the head side legs 11 a and 11 b of the main body frame 1 and the vertical frames 13 a and 13 b of the main body frame 1.

  When an earthquake occurs, a force is applied to the head frame 2 in the bedding placement direction. Then, the head frame 2 rotates about the rotation shaft 42 in the direction of the arrow in the figure, and the vertical column portions 21a and 21b of the head frame 2 come into pressure contact with the handrails 3a and 3b to become the protection position shown in FIG. As described above, when the vertical column portions 21aa and 21b are brought into pressure contact with the handrails 3a and 3b when the head frame 2 is in the protection position, a downward force is applied to the head frame 2 by a fallen object or a fallen object. When added, the head frame 2 is supported by the handrails 3a and 3b, so that it can withstand a large impact force. In addition, when the head frame 2 is in the protective position, the vertical portions of the handrails 3a and 3b have a height of 40 cm or more in order to secure a space for the human body to enter between the head frame 2 and the bedding placement surface. It is desirable to do.

  Further, when the head frame 2 is in the protection position, the vertical column portions 21a and 21b of the head frame 2 are pressed against the handrails 3a and 3b in order to withstand an impact caused by a fallen object or a falling object. Alternatively, for example, a configuration as shown in FIG. 9 may be used.

  The disaster prevention bed of FIG. 9 is similar to the third embodiment in that the vertical pillar portion 21a of the head frame 2 is formed on the upper end portions of the head side leg portions 11a and 11b that protrude upward from the bedding placement surface of the main body frame 1. , 21 b are pivotally connected by a pivot shaft 42. The support piece 6 is swingably attached to the side surfaces of the vertical column portions 21a and 21b. Specifically, the upper part of the support piece 6 is pivotally attached by a pin 43, and the lower end of the support piece 6 is a free end.

  As shown in FIGS. 9A to 9C, when the head frame 2 is rotated from the normal state to the protective state, the free end side of the support piece 6 on which the upper portion is pivoted always faces the direction of gravity. As the head frame 2 rotates, the support piece 6 forms a predetermined angle with the vertical column portion 21 a of the head frame 2. When the head frame 2 is in the protective position, the support piece 6 is substantially perpendicular to the head frame 2, and the lower end of the support piece 6 comes into contact with the vertical frame 13a (FIG. 3C). As a result, the head frame 2 is supported by the support piece 6 and can withstand even if a large downward impact force is applied to the head frame 2 by a fallen object or a fallen object. On the other hand, when the head frame 2 is rotated in the opposite direction to the normal position from the protective position, the support piece 6 is overlapped with the side surface of the vertical column portion 21a of the head frame 2 as the head frame 2 rotates. Stored.
