FIG. 1 and FIG. 2 show one embodiment of the safety protection device according to the present invention. Based on the simplicity of the structure, it is possible to easily and quickly carry, carry in, and assemble the work site, and the structure is simple and lightweight. However, it is an object of the present invention to provide an inexpensive safe protection device by effectively resisting an internal refugee from an earthquake by strongly resisting a collapse load and simplifying the structure. FIG. 1 is a plan view of the apparatus, and FIG. 2 is a front view of the apparatus of FIG.

  Reference numeral 1 denotes an existing floor material which is a tatami mat in a Japanese-style room, and its underfloor support structure is omitted in the drawing, but is composed of a floor bundle, a large pulling material, a joist material and an underfloor material. In addition, the flooring 1 may be a floor board (including one or two sheets of overlap finishing) as in a living room. Reference numeral 2 denotes a main protection frame, which is an iron round pipe bent at a right angle, and has a bending radius R of a large bending radius (for example, 70 to 80 cm) as well as a small bending radius (for example, 20 to 40 cm). There are things to do.

The main protective frame 2 is integrally provided with a vertical column portion 3 and a horizontal top surface portion 4, and a lower end of the column portion 3 is provided with a seat shaft 5 that can be freely inserted and removed as shown in the lower left column of FIG. A leg seat 6 is provided.
Four of these main protective frames 2 are prepared as common members, and are installed so that all the top surface portions 4... Extend toward the center of the plane of the ceiling surface. The portions extending in the center of the main protective frame 2 are coupled to each other through a fastening member 8 by a central joint 7.
The central joint 7 has a deformed X shape having a pipe portion extending in all directions at a constant angle. In the case of the embodiment, the first pipe 9 on the long side and the two second pipes on the short side are formed. The two second pipes 10 are in a relationship of projecting obliquely at an angle of about 60 with respect to the first pipe 9.

  The central joint 7 is welded and integrated with the tip of the top surface portion 4 of one main protective frame 2 or fixed at a regular angle (the surface formed by the main protective frame 2 and the surface formed by the central joint 7). (This is applicable to other embodiments as well). The fastening device 8 may be a type that holds the top surface portion 4 and a through bolt fixing type (illustrated embodiment) that penetrates the top surface portion 4, and employs other fastening methods. That is free.

  A construction method in which the central joint 7 is fixed by the installation stand 12 is also possible. In the case of this embodiment, the central joint 7 is sandwiched between the lower plate 13 and the upper plate 14 having the lifting / lowering adjuster function and is fastened and fixed by the fastening tool 15 so as to extend from the joint 7. The main protection frame 2... Is inserted into the first and second pipes 9 and 10 so as to be stopped. If the protrusion a is attached to the upper and lower sides of the crossing central portion of the central joint 7 and the hole b opened in the center of the upper plate 14 and the lower plate 13 is fitted as a positioning, the central joint 7 and the gantry 12 The centering can be easily and reliably performed. If the protrusion a is only on the upper surface side of the central joint 7, it is safe to prevent protrusions from appearing on the lower side.

The gantry 12 is installed on the floor as shown in phantom lines in FIG. 2, but the upper plate level of the lower plate 13 is higher than that shown in the figure (for example, about 20 cm higher) and adjusted and fixed. The lower end of the frame 2 ... can be mounted at a height that is raised above the floor surface (see Fig. 8). In this case, the lower end of the main protective frame 2 ... The main protective frame 2 inserted into the pipes 9 and 10 of the central joint 7 defined horizontally by the gantry 12 is in a state in which the column portion 3 naturally hangs vertically due to the action of gravity. It is easy to align the holes to be inserted, it is easy to insert the fasteners 8, and the assembly work can be performed quickly and reliably without having to maintain the state of the main protective frame 2 by vertically adjusting the angle. It made.
In the gantry 12, 16 is a base, 17 is a fixed screw pipe, 18 is a lock nut, 19 is a lifting screw shaft, and 20 is a lifting handle. The lower plate 13 includes a type that rotates together with the lifting screw shaft 19 and a type that rotates (swings) separately from the lifting screw shaft 19. In the latter case, even if the lifting screw shaft 19 is moved up and down, the central joint 7 does not rotate, so the direction of the apparatus does not change and the operation is easy. The gantry 12 may be a pantograph system. Further, when the laying device 22 (or bed) is laid (or installed) first, the pedestal 12 can constitute a pedestal 16 'so as to straddle them (FIG. 8, FIG. 12). (See FIG. 13).

  The leg seat 6 may be fixed integrally to the lower end of each main protection frame 2, or the seat shaft 5 with the leg seat 6 may be inserted as in the same embodiment. In the case of this embodiment, a Japanese style laying piece 22 which is a tatami mat is laid on the floor, and its four corners are placed on the leg seat 6. Since the wide surface portion that does not get on the leg seat 6 of the flooring 22 is likely to float, a spacer (such as plywood) c shown in the lower left column of FIG. Further, the bedding 22 has a corner chamfered so as to be close to the base of the main protective frame 2, and the corner portion is pressed by four pressers 23 provided around the main protective frame 2. The plate 24 is placed on the board. The holding plate 24 is coupled to the laying tool 22 by a fastener 25 such as a through bolt / nut or a screw from above. The presser 23 may be fixed to the main protective frame 2 by a fastening tool (a presser bolt type and a through bolt type) 8 as shown on the left side of FIG. 2, but as shown on the right side of FIG. You may make it not move by lever action by making it bite freely.

  The lining 22 is not a general size but a large custom size based on the size of a Japanese-style mattress / comforter, for example, a width of 1.5 m and a length of 2.3 m. Shall. The laying device 22 may be thickened to 1.5 times or 2 times instead of a general thickness. The lower right column of FIG. 2 exemplifies an example in which two or more sheets having a general thickness are overlapped, such as two sheets. The tool 22 and the main protective frame 2 exhibit more binding force. The presser 23 is not required when the bedding is a bed, but may be provided on the outer periphery of the column portion 3 as a reinforcing pipe.

Is regulated by the laying piece 22 and not only the stability of the main protection frame 2 in the earthquake is improved but also a large area. Floor slippage is also effectively prevented by the resistance of the laying tool 22. A bed as shown in FIG. 4 can be combined as an existing or new bed instead of the laying tool 22. The central joint 7 may be formed by resin integral molding. The main protective frame 2 may have another geometric cross-sectional shape such as a square pipe.

  A top frame 27 having a quadrilateral shape or a round shape may be attached to the constructed upper surface of the main protection frame 2 via a bracket 26 protruding on the main protection frame 2. In this case, it may be round like the virtual line in FIG. According to these top frames 27, the collapse damage through the V-shaped space left between the frames of the X-shaped main protection frame 2 is protected.

  On the top frame 27, a compression bag 28 containing a futon, a cushion, or the like that can hold a compressed state by removing air from the resin bag can be placed to exert a buffering action. In this case, the compression bag 28 can be held in the middle of compression and placed on the top frame 27, or a resin piece or sheet such as polystyrene foam or urethane can be placed in the bag. Styrofoam, urethane, or the like can be equipped as a buffer member. This can be applied to the following embodiments.

The center joint 7 has a pipe extending in all directions, but may be extended in five directions. For example, the main protective frame 2 may be provided on the back side by extending a pipe on the back side instead of the entrance side of the apparatus. Furthermore, as shown in the lower right column of FIG. 1, the pipe (or rod) of the central joint 7 may have a smaller diameter, and the pipe of the main protection frame 2 may be fitted on the outer periphery thereof.
As shown by a virtual line in the lower right column of FIG. 1, the central joint 7 may be one obtained by cutting a round pipe into a main body 33 and projecting four insertion pipes on the outer periphery thereof. . In this case, if the pipe is inserted into the cut-out main body 33 and welded, it becomes strong.

Further, as shown in the upper right column of FIG. 1, the central joint 29 is configured by combining a pair of protruding shafts 31 at both ends of a U-shaped main body 30 so as to be rotatable and tightenable around the central shaft 32. May be. In this case, all the projecting shafts 31 have the same height but may have different heights. In the case of this embodiment, the X-shaped crossing angle can be changed at the time of assembling work. For example, the angle formed by the main protective frame 2 inserted into the protruding shaft 31 can be changed. Since the position of the quadrilateral vertex formed by the base of the main protection frame 2 can be changed by allowing the main protection frame 2 to be inserted and removed freely, for example, the lower bed is an existing one and its dimensions are whatever. A common central joint 29 makes it possible to match it and build up the protective device.
