This device A is fixed to the floor surface (installation surface) F by the fall prevention metal fitting 20 of the first embodiment, and is prevented from being overturned when a shake such as an earthquake occurs. Hereinafter, although the fall prevention metal fitting 20 is explained in full detail, this metal fitting 20 is not limited to the said apparatus, It can apply also to various installations, such as another apparatus, furniture, and household appliances. .

  As shown in FIG. 2, the fall prevention metal fitting 20 of the present embodiment is fixed to the floor surface (installation surface) F on which the device A is installed, and is fixed to the lower end portion of the outer surface of the device A. Used in combination with the bracket fitting 10.

  The bracket metal fitting 10 is an L-shaped metal fitting composed of a plate portion 11 and a plate portion 12 which are orthogonal to each other. Of the two plate portions 11 and 12, the plate portion 11 is fixed to the device A side. On the other hand, the plate part 12 is engaged with the floor surface F side via the fall prevention metal fitting 20. A plurality (two in this case) of bolt insertion holes 11a are formed side by side in the longitudinal direction on the distal end side of the plate portion 11 on the device fixing side. On the other hand, one through hole 12a is formed through the plate portion 12 on the floor surface fixing side. The through hole 12a has a diameter larger than the diameter of a thread portion of an engagement bolt 32 described later.

  The bracket metal fitting 10 is positioned so that the plate portion 11 is aligned with the lower end portion of the outer surface which is the vertical surface of the device A, and the plate portion 12 is parallel to the floor surface F, that is, horizontal and slightly lifted from the floor surface F. Then, a bolt 31 such as a hexagon socket head bolt passed through the bolt insertion hole 11a of the plate portion 11 is screwed into the device A and fastened to be detachable and fixed integrally with the device A. A screw hole (not shown) into which the bolt 31 is screwed is provided on the device A side.

  The fall prevention metal fitting 20 of the present embodiment is a rectangular plate-shaped member, and straddles between the fixed portions 21 (first and second fixed portions) 21 at both ends in the longitudinal direction and the fixed portions 21. And a bridge portion 22. The bridge portion 22 includes a central horizontal portion 22a and inclined portions 22b at both ends, and an engagement screw hole 20a through which an engagement bolt 32 such as a hexagon socket head bolt is screwed is formed at the center of the horizontal portion 22a. ing. The horizontal portion 22a of the bridge portion 22 is parallel to the two fixing portions 21 on the same plane.

  As shown in FIG. 2B, the fall prevention metal fitting 20 has the fixing portions 21 at both ends fixed to the floor surface F via the adhesive member 25. In this state, the horizontal portion 22a of the bridge portion 22 is separated from the floor surface F by a predetermined distance, and a tunnel-like space 23 is formed between the horizontal portion 22a and the floor surface F. The space 23 has a width that allows the plate portion 12 of the bracket fitting 10 fixed to the device A to be inserted. A separation screw hole 24 into which the engagement bolt 32 is screwed is formed through one fixing portion 21 (on the right side in FIG. 2B) of the fall prevention metal fitting 20.

  The fall prevention metal fitting 20 of this embodiment which consists of the above structure is assembled | attached to the apparatus A installed in the floor surface F as follows. First, the bracket metal fitting 10 is fixed to the lower end portion of the outer surface of the device A. That is, the plate portion 11 is aligned with the outer surface of the device A, and the bolt 31 passed through the bolt insertion hole 11 a is screwed into the screw hole provided in the device A to fix the plate portion 11 to the device A. The bracket metal fitting 10 is fixed to the device A in a state where the plate portion 12 on the floor surface fixing side parallel to the floor surface F is slightly lifted from the floor surface F.

  Next, a pressure-sensitive adhesive member 25 is provided by sticking a double-sided pressure-sensitive adhesive tape on the back surfaces of the two fixing portions 21 (the surface opposite to the protruding direction of the bridge portion 22). Then, the bridge portion 22 is arranged above the plate portion 12 of the bracket metal fitting 10, and the fall prevention metal fitting 20 is pressed against the floor surface F at a position where the screw hole 20 a of the horizontal portion 22 a is continuous with the through hole 12 a of the plate portion 12. The fixing portion 21 is adhered to the floor surface F with an adhesive member. It is preferable that the fall prevention metal fitting 20 is fixed to the floor surface F in a state where the longitudinal direction is orthogonal to the longitudinal direction of the plate portion 12.

  Next, the engaging bolt 32 is screwed into the screw hole 20 a of the fall prevention metal fitting 20 from above, and the thread portion of the bolt 32 is inserted into the through hole 12 a of the bracket metal fitting 10. The engaging bolt 32 is screwed in until the head comes into contact with the upper surface of the horizontal portion 22a as shown in FIG. The threaded portion of the bolt 32 is inserted into the through hole 12a in a loosely fitted state with a slight gap between the inner peripheral surface of the through hole 12a.

  This completes the assembly of the fall prevention metal fitting 20. According to this fall prevention metal fitting 20, when a vibration such as an earthquake occurs, the threaded portion of the engagement bolt 32 hits and engages with the inner peripheral surface of the through hole 12a of the bracket metal fitting 10, thereby tilting the device A. It is regulated and falls are prevented. Further, during normal use, vibration from the floor surface F is transmitted from the fall prevention metal fitting 20 to the bolt 32, but the screw portion of the bolt 32 is loosely fitted in the through-hole 12a and is not in contact with the bracket metal fitting 10. The vibration of the surface F is not transmitted to the device A through the fall prevention metal fitting 20. Therefore, the fall-preventing metal fitting 20 is suitable for a device that does not want to be greatly affected by the vibration of the floor surface F. Further, the large lateral swing (in the direction parallel to the floor surface F) is restricted by the threaded portion of the bolt 32 striking and engaging the inner peripheral surface of the through hole 12a.

  Now, in the case of the device A, removal from a fixed place may be required, such as relocation with the addition of other devices. At that time, the engagement bolt 32 is removed from the fall-preventing metal fitting 20, and the bolt 32 is screwed into the peeling screw hole 24 of the fixing portion 21 from above. Then, the bolt 32 is further screwed from the state where the tip is in contact with the floor surface F. Then, a reaction force with respect to the screwing direction of the bolt 32 is generated, and the fixing portion 21 that is screwed is separated from the floor surface F against the adhesive force of the adhesive member 25. Thereby, the fall prevention metal fitting 20 can be peeled from the floor surface F. Since the fall prevention metal fitting 20 is detached from the bracket metal fitting 10 and the engagement is released, the device A can be moved. When the device A is installed in another place, the fall prevention metal fitting 20 may be assembled to the device A again by the above procedure.

  According to the fall prevention metal fitting 20 of this embodiment, the fall prevention structure can be obtained by an easy operation of fixing the metal fitting 20 to the floor surface F with the adhesive member 25 and screwing the engagement bolt 32. Further, since the adhesive member 25 is used as a means for fixing the fall prevention metal fitting 20 to the floor surface F, there is no need to provide the floor surface F with an anchor hole into which an anchor bolt is driven as in the prior art. The attachment / detachment of the fall-preventing metal fitting 20 to the floor surface F is performed by adhesion by the adhesive member 25 and the screwing operation of the bolt 32 into the peeling screw hole 24, so that it is extremely easy and reduces the burden of the attachment / detachment work. . Further, since the bolts used for screwing into the peeling screw holes 24 and peeling the fall prevention metal fitting 20 from the floor surface F are also used as the engaging bolts 32, the number of parts can be reduced and the peeling bolts can be used. There is an advantage that a troublesome thing to prepare and manage it is saved.

[2] Modified Example of First Embodiment FIG. 3 shows a modified example of the overturn preventing metal fitting 20 of the first embodiment: the overturn preventing metal fitting 20B. In this modification, the screw hole into which the engagement bolt 32 is screwed and the through hole into which the screw portion of the bolt 32 is loosely fitted are formed in a state opposite to that in the first embodiment. That is, the engagement screw hole 12 b into which the engagement bolt 32 is screwed is formed in the plate portion 12 of the bracket metal fitting 10, and the screw portion of the bolt 32 is loosely fitted in the horizontal portion 22 a of the bridge portion 22 of the fall prevention metal fitting 20. A through-hole 22c is formed through. The bolt 32 is inserted into the through-hole 22 from above, the screw portion of the bolt 32 is screwed into the screw hole 12b, and the head is in contact with the upper surface of the horizontal portion 22a.

  In this case, the fall prevention metal fitting 20 is fastened to the bracket metal fitting 10 by the bolt 32. Therefore, although the vibration of the floor surface F is transmitted to the device A via the fall prevention metal fitting 20B, the device A is firmly fixed to the floor surface F by the fall prevention metal fitting 20B. In addition, the load of the device A is transmitted to the fall prevention metal fitting 20 through the bracket metal fitting 10 and the engagement bolt 32, and as a result, the force with which the fall prevention metal fitting 20 presses the adhesive member 25 against the floor surface F increases. The adhesion to the surface F is improved. For this reason, the fall prevention metal fitting 20 is fixed more firmly with respect to the floor surface F, and the improvement of the fall prevention effect is achieved.

  Further, the peeling screw hole 24 formed in the fall prevention metal fitting 20 is formed in the horizontal portion 22 a of the bridge portion 22. The screw hole 24 is formed on the back side (device A side) of the through hole 22c, and the tip of the bolt 32 screwed into the screw hole 24 is in contact with the upper surface of the plate portion 12 of the bracket metal fitting 10. Yes. In the fall prevention metal fitting 20, the tip of the bolt 32 abuts against the floor surface F and a reaction force is generated to peel the fall prevention metal fitting 20 from the floor surface F. In this modification, the tip of the bolt 32 is A reaction force that abuts against the plate portion 12 and causes the fall prevention metal fitting 20 to peel off is generated.

[3] Second Embodiment FIG. 4 shows a fall prevention metal fitting 40 according to a second embodiment of the present invention. The metal fitting 40 uses the bracket metal fitting 10 (a screw hole 12b is formed in the plate portion 12 on the floor surface fixing side) shown in FIG. 3 as a common component. In the fall prevention metal fitting 40, a hollow block (bridge portion) 45 having a horizontally long rectangular cross section is fixed to the upper surface of a rectangular fixed plate 41 by means such as welding. In this case, both end portions of the fixing plate 41 are the first and second fixing portions of the present invention.

  In the hollow block 45, an insertion hole 46 penetrating in a direction orthogonal to the longitudinal direction of the fixed plate 41 is formed. The insertion hole 46 has a width that allows the plate portion 12 of the bracket fitting 10 to be inserted. In the center of the horizontal portion 47 on the upper side of the hollow block 45, a through hole 47a into which the thread portion of the engagement bolt 32 is loosely fitted is formed. Further, a peeling screw hole 47b through which the engaging bolt 32 is screwed is formed through the horizontal portion 47. The peeling screw hole 47b is formed at a position adjacent to the through hole 47a in the width direction of the horizontal portion 47.

  In order to assemble the fall prevention metal fitting 40 of this embodiment to the device A installed on the floor F, first, a double-sided adhesive tape is applied to the back surface of the fixing plate 41 (the surface opposite to the fixing surface of the hollow block 45). The adhesive member 25 is provided by sticking. Then, with the peeling screw hole 47b arranged on the device A side, the plate portion 12 of the bracket fitting 10 fixed to the device A is passed through the insertion hole 46 of the hollow block 45, and the through hole 47a of the horizontal portion 47 is the plate portion. At a position continuous with the twelve screw holes 12b, the fall prevention metal fitting 40 is pressed against the floor surface F, and the fixing plate 41 is adhered to the floor surface F. Next, the engaging bolt 32 is passed through the through-hole 47 a and screwed into the screw hole 12 b of the bracket fitting 10 until the head comes into contact with the upper surface of the hollow block 45, and the bracket fitting 10 is fastened to the hollow block 45. This completes the assembly of the fall prevention metal fitting 40 to the device A.

  Further, when the device A is removed from the fixed place, the engagement bolt 32 is removed, and the bolt 32 is screwed into the peeling screw hole 47b of the fall prevention metal fitting 40 from above. The front end of the bolt 32 abuts on the upper surface of the plate portion 12 of the bracket metal fitting 10, and further the screw 32 is screwed, so that the fixing plate 41 is peeled from the floor surface F against the adhesive force of the adhesive member 25 by the generated reaction force.
