  In such a contact state, the left and right positioning L-shaped ribs 5, 5 ′ of the storage box 2 and the front surfaces 5 a, 5 a ′, 5 a ″ of the upper positioning L-shaped rib 5 ″ and the frame-shaped frame 8 The mounting plane 8d is close to the frame 8 while maintaining the same distance t2 (the frame mounting position) (FIG. 8C).

  In such a state, the front insertion hole 11 of the mounting plane 8d and the rear insertion hole 6 of the front surfaces 5a, 5a ′, 5a ″ of the storage box 2 have the same center line p. Is located.

  Next, in the mounting state of the frame-shaped frame 8, the engaging pin 12 is directed from the front side of the mounting plane 8d toward the insertion hole 11 side, and the head is placed in each insertion hole 11. Insert until the rear surface 12b 'of 12b abuts against the mounting plane 8d.

  At this time, by inserting the engagement pin 12 into the insertion hole 11, as shown in FIG. 9A, the rear surface 12b ′ of the head 12b comes into contact with the front surface of the mounting plane 8d, and the engagement pin 12 is inserted into the pin fixing bush 20 fitted in the insertion hole 6. At this time, the insertion of the engagement pin 12 causes the tapered surface 23 a ″ of the annular inward projection 23 a of the cylindrical engagement portion 23 of the bush 20 to contact the parallel annular projection 13 of the engagement pin 12. Although the diameter of the annular inward projection 23a is enlarged by the action of 23b, the annular inward projection 23a is elastic in the direction of arrow B according to the distance t2 between the mounting plane 8d and the front surface 5a (5a ′, 5a ″). It returns and engages with the shaft portion 12a at a predetermined position in the engagement pin 12, whereby the engagement pin 12 is prevented from coming off.

  In this state, as shown in FIG. 10, the parallel annular ring engaged with the vertical surface 23a ′ of the engagement pin 12 over the entire circumference (360 degrees) of the vertical surface 23a ′ of the annular inward projection 23a. When a tightening load (compression load) in the direction of arrow A is applied from the protrusion 13 and the tightening load is applied to the cylindrical engagement portion 23, the engagement portion 23 is provided with slits 23b and 23b. A tightening force in the inward projection 23a (in the direction of arrow B), that is, in the direction of the main shaft 12a of the engagement pin 12, is generated over the entire circumference, whereby the engagement pin 12 is firmly fixed to the bush 20.

  At this time, the vertical surface 23a ′ is orthogonal to the outer peripheral surface of the cylindrical engaging portion 23 of the pin fixing bush 20, and the surface of the parallel annular protrusion 13 of the engaging pin 12 engaged therewith. Since 13 ′ is also a vertical surface parallel to the vertical surface 23a ′, the annular vertical surface 23a ′ and the annular surface 13 ′ are in contact with each other, and the contact area between the two is large. A sufficient tightening load can be applied to the vertical surface 23 a ′ over the entire vertical surface 23 a ′, whereby both can be firmly fixed.

  Then, by inserting the engaging pin 12 through the insertion hole 11 and the insertion hole 6 (six places) at the left and right symmetrical positions and the upper insertion hole 11 and the insertion hole 6 (one place) in the same manner, The frame-like frame 8 in which the rear edge 8b ′ of the portion 8b is in contact with the wall surface 3 over the entire circumference is connected to the front surfaces 5a, 5a of the positioning L-shaped ribs 5, 5 ′, 5 ″ of the storage box 2. It can be firmly fixed to “5a”.

  At this time, the engaging pin 12 only needs to be pushed into the insertion hole 11 until the rear surface 12b ′ of the head 12b abuts against the front surface of the mounting plane 8d. The annular inward projection 23a is engaged with any one of the parallel annular projections 13 of the engagement pin 12 in accordance with the distance t2 between the L-shaped ribs 5, 5 ′, 5 ″ for the front surfaces 5a, 5a ′, 5a ″. As a result, the engagement pin 12 is connected to the frame 8 in a retaining state. Accordingly, the interval t2 between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″ is maintained at a constant interval along the frame-like frame 8, and the frame-like frame 8 is placed in the fire-extinguishing equipment storage box 2 in this state. (See FIG. 9A).

  Reference numeral 25 denotes an annular spacer interposed between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″, and the engagement pin 12 is inserted into the central hole 25a of the spacer 25. And between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″. The annular spacer 25 is not necessarily required, but has a function of stabilizing the fixation of the both when the interval t2 between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″ is large. The annular spacer 25 can be easily manufactured by cutting a cylindrical body 25 ′ as shown in FIGS. 12A and 12B to a predetermined length (for example, h) at the site.

  FIG. 13 and FIG. 14 show another embodiment of the present invention. Instead of the engagement pin 12 having the parallel annular protrusion 13, the engagement pin 26 using a screw screw having a normal thread 26 'is used. Is. Also in this case, the engaging pin 26 and the pin fixing bush 20 are fixed by engaging the annular inward projection 23a of the pin fixing bush 20 with the screw thread 26 'of the screw screw 26. In this case, since the thread 26 'forms a tapered surface 26a with respect to the vertical surface 23a' behind the annular inward projection 23a (FIG. 14), the taper surface 26a extends from the vertical surface 23a '. A round tightening load (compression load) (in the direction of arrow A) is applied to the entire circumference (360 degrees) (see FIG. 14), whereby the vertical surface 23a ′ is deformed inwardly along the tapered surface 26a, and the cylinder The engaging portion 23 (annular inward projection 23a) is deformed in the direction of arrow B (in the direction of the center of the cylinder) by the action of the slit 23b, thereby securing the attachment strength between the engaging pin 26 and the pin fixing bush 20. be able to.

  As described above, even when the engagement pin 26 is used, the frame-like frame 8 can be easily attached to the fire extinguishing equipment storage box 2 as in the case where the engagement pin 12 is used. In this case, a general-purpose screw screw can be used, and there is an effect that a dedicated engagement pin is not required. Reference numeral 26b denotes a large-diameter head of the engaging pin 26.

  As described above, according to the present invention, when the frame-shaped frame 8 is attached to the storage box 2, the troublesome operation such as making the tightening torques of the left and right bolts constant is not required as in the conventional bolt tightening. After the pin fixing bush 20 is fitted into each insertion hole 6 of the L-shaped rib for positioning of the box 2 and the frame-like frame 8 is positioned, the head 12b of the engaging pin 12 is brought into contact with the front surface of the mounting plane 8d. The frame-shaped frame 8 can be fixed to the fire extinguishing equipment storage box 2 without distortion by an extremely simple operation of pushing in until it comes into contact.

  Further, depending on the site, as shown in FIG. 15, by attaching a wall plate 3 ′ having a predetermined thickness to the wall surface of the opening periphery of the storage recess 4, the upper peripheral folding surface of the frame-like frame 8 is formed. When the rear edge 8b ′ of 8b is positioned on the near side by the thickness of the wall plate 3 ′, thereby the interval t2 between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″ is widened (t2 in the figure). In this case, as in the case described above, the engaging pin 12 is simply pushed into the insertion hole 11 until the head 12b contacts the front surface of the mounting plane 8d. Similarly, any one of the engaging pins 12 is parallel according to the distance t2 ′ between the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″ of the positioning L-shaped ribs 5, 5 ′, 5 ″. The annular protrusion 13 engages with the annular inward protrusion 23a of the pin fixing bush 20, and this Makes it possible to fix the frame 8 in the strain without the fire extinguishing equipment storage box 2.

  Accordingly, the mounting plane 8d and the front surfaces 5a, 5a ′, 5a ″ are in a state of being kept at a constant interval (t2) along the frame-like frame 8, and in this state, the frame-like frame 8 is placed in the fire extinguishing equipment storage recess 2. Therefore, even if the interval (t2) changes, a troublesome operation such as making the left and right torques uniform according to the change in the interval is required as in conventional bolt tightening. Instead, the frame-shaped frame 8 can be connected and fixed to the fire-extinguishing equipment storage box 2 very easily by simply pushing the engaging pin 12.

  Further, the engagement pin 12 and the pin fixing bush 20 are coupled to the entire circumference (360 degrees) of the vertical surface (rear end surface) 23a ′ of the annular inward projection 23a of the engagement bush 20. By applying a tightening load of the parallel annular protrusion 13 of the pin 12, the bush 20 and the engagement pin 12 can be firmly fixed, and thereby the frame-shaped frame 8 can be securely and securely attached to the fire extinguishing equipment storage box 2. Can be firmly attached.

  Note that the change in the interval t2 is not limited to the case where the frame-like frame 8 is moved forward by the wall plate 3 ′ as described above, but the fire-extinguishing equipment storage box 2 is moved rearward depending on the depth of the rectangular storage recess 4. In any case, the frame-shaped frame 8 can be reliably fixed at an interval within the installation range of the parallel annular protrusions 13 of the engagement pin 12.

  As described above, in the present invention, in a state where the frame-shaped frame 8 is positioned at the frame mounting position, the frame-shaped frame 8 and the fire extinguisher can be extinguished only by inserting the engaging pin 12 into the pin fixing bush 20 from the front insertion hole 11. The equipment storage box 2 can be connected and fixed. At this time, the frame-like frame 8 and the above-described one of the parallel annular protrusions 13 of the engagement pins 12 respectively corresponding to the front surfaces 5a, 5a ′, 5a ″ and the position (fixed position) of the frame-like frame 8 are used. Since the front surfaces 5a, 5a ′, 5a ″ can be fixed, the frame-like frame 8 and the front surfaces 5a, 5a ′, 5a ″ are mutually spaced apart by a simple operation of inserting the engagement pin 12. Can be fixed.

  Moreover, the frame-shaped frame 8 and the fire extinguishing equipment storage box 2 are coupled to the engagement pin 12 by applying a tightening load of the engagement pin 12 to the entire circumference of the annular inward projection 23 a of the pin fixing bush 20. Since it is performed by coupling with the pin fixing bush 20, the frame-shaped frame 8 can be firmly fixed to the fire extinguishing equipment storage box 2.

  In addition, the frame-shaped frame 8 can be attached to the storage box 2 simply by inserting the engaging pins 12 into the respective insertion holes 11 in the positioning state in which the frame-shaped frame 8 is in contact with the wall surface 3. Thus, the frame-like frame 8 can be attached and fixed to the storage box 2.

  Further, in the frame positioning state of the frame-shaped frame 8, the penetration position of the rear insertion hole 6 and the penetration position of the front insertion hole 11 hold a constant interval t <b> 2 along the frame-shaped frame 8. Therefore, after that, the frame-like frame 8 can be fixed without distortion simply by inserting the engaging pins 12 into the respective insertion holes 11.

  Moreover, the said frame 8 can be easily attached to the fire extinguishing equipment storage box 2 in the state which made the attachment height (front-back direction height) of the upper and lower sides and the left and right with respect to the storage box 2 of the frame-shaped frame 8 the same.

  Further, when the frame-shaped frame 8 is fixed to the front side of the fire-extinguishing equipment storage box 2, the frame-shaped frame 8 can be attached without distortion by a simple operation of inserting the engagement pin 12, and the fire-extinguishing equipment storage box The work efficiency of the assembly work can be greatly improved.

  Further, in a state where the frame-shaped frame 8 is held in the positioning state at the frame mounting position, the rear insertion hole penetration position and the front insertion hole penetration position are held at a constant interval along the frame frame 8. Since it comprised, the frame-shaped frame 8 can be attached to the fire extinguishing equipment storage box 2 without distortion by simple operation of inserting the engagement pin 12.

  Moreover, since either the parallel screw or the screw screw in which the parallel annular protrusion 13 is formed can be used as the engaging pin, the existing parallel screw or the screw screw can be used as the engaging pin 12, and it is structurally versatile. It has the advantage that it can be installed inexpensively using off-the-shelf screws.

  Moreover, the frame mounting structure of the fire-extinguishing equipment storage box according to the present invention has an advantage that it can be easily constructed in a closed narrow space such as a corridor. In FIG. 1, 19 is a handle of the door 10 and 27 is a fire hydrant display.

  In the above embodiment, the cross-section of the engagement pin is circular, and the pin fixing bush is cylindrical. However, the present invention is not limited to this, and the cross-section of the engagement pin is formed in a square shape, and the pin fixing bush The through hole 20 ′ may be a through hole having a quadrangular cross section corresponding to this. Further, the parallel annular protrusions of the engagement pin may be any surface as long as at least the surface facing the vertical surface 23a 'is a vertical surface, and the surface on the distal end side of the engagement pin may be a tapered surface.
