Description

Technical Field

[0001] The present invention relates to a fire extinguisher holder.

Background Art

[0002] Installation of fire extinguishers is mandated by laws and regulations for buildings and the like, and various types of fire extinguisher holders have been proposed.

[0003] There are types such as the fire extinguisher holders disclosed in Patent Documents 1 to 3, in which a case for accommodating a fire extinguisher is embedded in a wall or the like, and a suspendable type such as the fire extinguisher holder disclosed in Patent Document 4. These fire extinguisher holders are effective for special applications such as tunnels, vehicles, and construction sites.

[0004] In general commercial facilities and stores where products are displayed on display shelves, fire extinguisher holders are placed in aisles or along walls, and in most cases, fire extinguishers are installed in an upright posture. The inventions disclosed in Patent Documents 5 and 6 are fire extinguisher holders that support fire extinguishers of various dimensions and simply hold the fire extinguisher upright to be installed in aisles or along walls, but they are prone to tipping over, and it becomes necessary to move or lift them every time cleaning is performed, which becomes an obstacle to cleaning. In this regard, the fire extinguisher holders disclosed in Patent Documents 7 and 8 can be fixed to a wall surface to prevent tipping over, but they damage the wall and cannot solve the problem of being an obstacle to cleaning either.

[0006] Therefore, the present invention provides a fire extinguisher holder that accommodates fire extinguishers of different sizes, prevents them from tipping over, and does not interfere with cleaning. [Means for solving the problem]

[0007] The fire extinguisher holder according to the present invention has a bottom plate and a back plate connected in an L-shape when viewed from the side, on which the fire extinguisher is placed, and a hook is provided on the front of the back plate for engaging with a hollow locking part erected on the side of the fire extinguisher. A fire extinguisher holder that can be attached to a mesh frame, which comprises a rectangular parallelepiped frame and a mesh section between the frame sections, where mesh wires connect in the vertical and horizontal directions, the upper and lower parts of the back plate each have screw holes on the left and right sides, respectively, and the upper narrow plate has screw holes drilled on the left and right sides to match the spacing between the left and right screw holes on the upper part of the back plate, respectively, and a lower narrow plate has screw holes drilled on the left and right sides to match the spacing between the left and right screw holes on the lower part of the back plate, the upper narrow plate and the lower narrow plate has screw holes drilled on the left and right sides to match the spacing between the left and right screw holes on the lower part of the back plate, The upper and lower narrow plates are brought into contact with the back sides of the left and right screw holes on the upper and lower parts of the back plate, respectively, sandwiching the mesh portion of the mesh frame, and the left and right screw holes on the upper and lower parts of the back plate are aligned with the left and right screw holes on the upper and lower narrow plates, respectively. By passing screws through all of these aligned screw holes and fastening them, the upper narrow plate, the lower narrow plate, and the back plate can be fixed together and the back plate can be attached to the mesh frame.

[0008] In this specification, "screw fastening" refers to fixing two objects to be fixed together by passing a screw through screw holes drilled in those objects, and "screw" includes male screws, bolts, screws, pins, etc. The "screw" can be fixed to the objects by passing it through a screw hole, screwing it into a female screw cut into a screw hole or into a nut placed against the back of the object, or by other means such as adhesive.

[0009] In the fire extinguisher holder according to the present invention, the hook device provided on the back plate is a plate-like body in which a fixing part and a hook part above it are connected in a stepped manner in a side view by a connecting part, and the hook device is screwable into two elongated holes, each having a major axis in the vertical direction d, which are drilled in the center of the left and right sides of the back plate with a vertical distance Δd between them. The hook can be fixed to the back plate by passing screws through the two screw holes drilled in the fixing portion of the hook and the two elongated holes drilled in the back plate, and then screwing them into nuts located on the back side of the back plate.

[0010] In the fire extinguisher holder according to the present invention, the two screws that pass through the two screw holes in the fixing part of the hook and the two elongated holes in the back plate are movable between the upper and lower ends of the two elongated holes with a major axis d in the vertical direction, and can be fixed by nuts placed on the back side of the back plate after selecting an appropriate position between the upper and lower ends of the two elongated holes.

[0011] The fire extinguisher holder according to the present invention is preferably attached to the mesh frame of the display shelf, with the bottom plate spaced apart from the ground on which the display shelf is placed.

[0012] The fire extinguisher holder according to the present invention may have frame pieces protruding from at least the left and right sides of the back plate in the same direction as the bottom plate. Alternatively, frame pieces may be protruding from the left and right sides and the top edge of the back plate in the same direction as the bottom plate. [Effects of the Invention]

[0013] A fire extinguisher holder according to the present invention places a fire extinguisher on a bottom plate, and locks and holds the fire extinguisher by engaging a hook member of a back plate with a hollow locking portion provided on a side portion of the fire extinguisher. Since such a fire extinguisher holder of the present invention can be attached to a mesh-shaped frame body used for side plates of product shelves, display shelves, racks and the like, there is no need to place it directly on the floor of a passage or the like.

[0014] That is, in the fire extinguisher holder according to the present invention, the back plate can be attached to the mesh-shaped frame body by bringing an upper thin plate and a lower thin plate into contact with the respective back surface sides of the upper portion and the lower portion of the back plate across the mesh portion of the mesh-shaped frame body and fastening them with screws. Therefore, the bottom plate can be separated from the floor or the ground and attached to a display shelf or the like, and falling can be prevented without damaging the wall.

[0015] Further, as described above, since the bottom plate is arranged to be positioned above the floor, the head brush of the hose of a vacuum cleaner can be inserted between the bottom plate and the floor. Therefore, with the fire extinguisher holder of the present invention, it is no longer necessary to move or lift the fire extinguisher holder every time cleaning is performed as in the conventional case, and cleaning can be carried out smoothly to maintain the cleanliness of stores and the like.

[0016] Further, in the fire extinguisher holder of the present invention, the stepped hook member has an upper hook portion that locks the hollow locking portion of the fire extinguisher, and a lower fixing portion that is screwed into two long holes with a length of d drilled in the back plate. Therefore, the screws for screwing the hook member to the back plate can be positioned up and down within the range of the length d of the long holes, and the size of the bottom plate on which the fire extinguisher is placed is also arbitrary, so that the fire extinguisher holder of the present invention can be adapted to fire extinguishers of various dimensions.

[0017] In the fire extinguisher holder according to the present invention, frame pieces may be projected in the same direction as the bottom plate at least on the left and right sides of the back plate. Alternatively, frame pieces may be projected in the same direction as the bottom plate on the left and right sides and the upper side of the back plate, so that the stored fire extinguisher can be protected from external force and the like.

[Modes for Carrying Out the Invention]

[0019] Hereinafter, embodiments and examples of the fire extinguisher holder according to the present invention will be described with reference to the drawings. Note that the same reference numerals are used for the same components throughout the following respective drawings.

[0020] (Fire extinguisher holder according to the present invention) The fire extinguisher holder 1 according to the present invention has, for example, as shown in Fig. 1 or Fig. 3(a) and (b), a bottom plate 10A and a back plate 10B connected in an L-shape in side view, the fire extinguisher 3 is placed on the bottom plate 10A protruding in the front direction of the back plate 10B, and the fire extinguisher holder 1 is provided with a hook member 30 on the front surface of the back plate 10B, which engages with a hollow locking portion 31 (see Fig. 3(a)) erected on the side portion of the fire extinguisher 3.

[0021] (Upper thin plate and lower thin plate) As shown in Figure 4(a), the fire extinguisher holder 1 of the present invention has screw holes (12u, 12u) and (12d, 12d) on the left and right sides of the upper and lower parts of the back plate 10B, respectively. Furthermore, as shown in Figure 4(c), the fire extinguisher holder 1 of the present invention includes an upper narrow plate 20u and a lower narrow plate 20d for contacting the back surfaces of the upper and lower parts of the back plate 10B. The upper narrow plate 20u has left and right screw holes (22u, 22u) drilled in it so as to match the spacing of the left and right screw holes (12u, 12u) on the upper part of the back plate 10B. Similarly, the lower narrow plate 20d has left and right screw holes (22d, 22d) drilled in it so as to match the spacing of the left and right screw holes (12d, 12d) on the lower part of the back plate 10B.

[0022] (material) The materials for the bottom plate 10A, back plate 10B, upper narrow plate 20u, and lower narrow plate 20d that constitute the fire extinguisher holder 1 are preferably metal, wood, plastic, etc., but are not particularly limited. In addition, the bottom plate 10A and back plate 10B may be integrally molded.

[0023] (Mesh-like frame) The fire extinguisher holder 1 according to the present invention can be attached to a mesh frame 50, as shown in Figures 4(a) to (c), which consists of a rectangular parallelepiped frame 52 and a mesh section 54 in which mesh wires connect the frame in the vertical and horizontal directions. The mesh frame 50 can be used, for example, as a side panel for an assembly-type product shelf, display shelf, rack, etc.

[0024] In addition, the mesh frame 50 used in commercial facilities and stores often has a spacing of 5 cm between the vertical and horizontal mesh wires that make up the mesh portion 54. Furthermore, the frame portion 52 of the mesh frame 50 can be made of metal, wood, plastic, etc., and the mesh wires of the mesh portion 54 are often made of metal wire covered with vinyl or the like, but these materials and constructions are not particularly limited.

[0025] (attachment) The method for attaching the fire extinguisher holder 1 of the present invention to the mesh frame 50 is as follows. That is, as shown in Figures 2(a) to (f), first, the upper narrow plate 20u and the lower narrow plate 20d are brought into contact with the back sides of the upper and lower left and right screw holes (12u, 12u) and (12d, 12d) of the back plate 10B, respectively, with the mesh portion 54 of the mesh frame 50 in between.

[0026] Then, the left and right screw holes (12u, 12u) and (12d, 12d) on the upper and lower parts of the back plate 10B are aligned with the left and right screw holes (22u, 22u) and (22d, 22d) on the upper narrow plate 20u and the lower narrow plate 20d, respectively, and screws 110 are passed through all of these aligned screw holes (12u, 22u) and (12d, 22d) to fasten them (see Figures 4(a) to (c)). By fastening them with screws via the mesh part 54 in this way, the fire extinguisher holder 1 of the present invention can fix the upper narrow plate 20u and the lower narrow plate 20d to the back plate 10B, and the back plate 10B can be attached to the mesh frame 50.

[0027] Specifically, the left and right screws (110, 110) are passed through the left and right screw holes (22u, 22u) of the upper narrow plate 20u from the back side, and are positioned to hook onto the top of the mesh wires of the mesh section 54, so that the front of the upper narrow plate 20u is brought into contact with the back of the back plate 10B, sandwiching the mesh section 54. Then, these left and right screws (110, 110) are screwed into the left and right screw holes (12u, 12u) of the back plate 10B, respectively, so that the back plate 10B can be attached to the mesh frame 50 as shown in Figure 4(b). At a minimum, the left and right screws 110 that pass through the left and right screw holes (22u, 22u) of the upper narrow plate 20u and the left and right screw holes (12u, 12u) of the back plate 10B hook onto the top of the mesh wires, so that the back plate 10B can be attached to the mesh section 54 without falling.

[0028] Furthermore, for the screws 110 that pass through the top, bottom, left, and right screw holes 12u and 12d of the back plate 10B, it is preferable to use a pair of square-head bolts 110 and wing nuts 111 as shown in Figure 4(b) for ease of handling. It is also preferable to provide female threads in the screw holes drilled in the upper narrow plate 20u and the lower narrow plate 20d and fix the wing screws 110 to them. [Examples]

[0029] In Figures 1 to 4, which show an embodiment of the present invention, a square-head bolt 110 is passed through the screw holes (22u, 22u) and (22d, 22d) of the upper narrow plate 20u and the lower narrow plate 20d, and the screw holes (12u, 12u) and (12d, 12d) of the back plate 10B from the back side, and fastened with a wing nut 111 on the front side of the back plate 10B (see Figures 4(a) to (c)).

[0030] (Hook) In the fire extinguisher holder 1 according to the present invention, the hook 30 provided on the back plate 10B is a plate-like body in which a lower fixing part 30B and an upper hook part 30A are connected by a connecting part 30M, as shown in Figure 1 or Figure 3(a), and is connected in a stepped manner in side view. Two screw holes 32u and 32d are drilled in the fixing part 30B with a gap of d+Δd in the vertical direction (see Figure 1).

[0031] (long hole) As shown in Figures 4(a) and (c), two elongated holes 14u and 14d are provided near the center of the back plate 10B. The major axis of these two elongated holes 14u and 14d in the vertical direction is d, and they are drilled in the back plate 10B with a gap Δd between them in the vertical direction.

[0032] As described above, the hook 30 has two screw holes 32u and 32d drilled in its fixing portion 30B with a vertical distance of d+Δd between them (see Figure 4(b)). The hook 30 can be fixed to the back plate 10B by passing a screw 110 through these two screw holes 32u and 32d and through two elongated holes 14u and 14d drilled in the back plate 10B, and then fastening it with a nut 111 or the like that which is in contact with the back side of the back plate 10B.

[0033] The diameter of the nut 111 used for screw fastening should be sufficiently larger than the minor axis in the left-right direction of the two elongated holes 14u and 14d. Alternatively, as shown in Figure 2(d), a square-head bolt may be used as the screw 110, passing through the screw holes 32u and 32d of the fixing part 30B and the elongated holes 14u and 14d of the back plate 10B, and then fastened with a wing nut 111. [Examples]

[0034] In this embodiment (Figures 1 to 4), the screw fastening is performed by passing a square-head bolt 110 through the screw holes 32u and 32d of the fixing part 30B and the elongated holes 14u and 14d of the back plate 10B from the front side of the fixing part 30B of the hook fitting 30, and then screwing a wing nut 111 onto the back side of the back plate 10B (see Figures 4(a) to (c)).

[0035] (Hook placement) Two screws 110, which pass through the two screw holes 32u and 32d of the fixing part 30B of the hook fitting 30 and the two elongated holes 14u and 14d of the back plate 10B, can move between the upper and lower ends of the two elongated holes 14u and 14d, which have a major axis d in the vertical direction. Therefore, the fire extinguisher holder 1 of the present invention can select an appropriate position between the upper and lower ends of these two elongated holes 14u and 14d and fix the hook fitting 30 with a nut 111 placed on the back side of the back plate 10B.

[0036] In other words, the screws 110 that fasten the hook 30 to the back plate 10B can be positioned within the range of the major axis d of the elongated holes 14u and 14d, and the size of the bottom plate 10A on which the fire extinguisher 3 is placed is also arbitrary, so the fire extinguisher holder 1 of the present invention can accommodate fire extinguishers 3 of various dimensions.

[0037] (Bottom plate arrangement) Furthermore, the fire extinguisher holder 1 according to the present invention is preferably attached to the mesh frame 50 of the display shelf 100 such that the bottom plate 10A is spaced apart from the floor or ground on which the display shelf 100 is placed, for example, as shown in Figures 4(a) to (c), at a height of Δh above the floor. By attaching the bottom plate 10A to the display shelf, etc., spaced above the floor, it is possible to prevent it from tipping over and to solve the problem of it being an obstacle to cleaning.

[0038] (frame piece) The fire extinguisher holder 1 according to the present invention may have frame pieces 16 (16l, 16r) projecting from at least the left and right sides of the back plate 10B in the same direction as the bottom plate 10A, although this is not shown in the figures. Alternatively, frame pieces 16 (16l, 16r, 16u) may be projecting from the left and right sides and the top edge of the back plate 10B in the same direction as the bottom plate 10A. This allows the housed fire extinguisher to be protected from external forces and the like. [Examples]

[0039] In the fire extinguisher holder 1 of this embodiment shown in Figures 4(a) to 4(c), the spacing between the vertical and horizontal mesh lines forming the mesh portion 54 of the mesh frame 50 that secures it is set to 10 cm for convenience. Therefore, the vertical frame of the mesh frame 50 is approximately 110 cm, and the horizontal frame is approximately 60 cm.

[0040] Furthermore, the two elongated holes 14u and 14d drilled in the back plate 10B of the fire extinguisher holder 1 both have a major axis in the vertical direction of d = 8 cm, and the distance between the elongated holes 14u and 14d is Δd = 2 cm. Therefore, the distance between the screw holes 32u and 32d drilled in the fixing part 30B of the hook 30 is d + Δd = 10 cm (see Figure 4(b)).

[0041] The method for attaching the fire extinguisher holder 1 to the mesh frame 50 is as shown in Figures 4(a) to (c), as described above. Specifically, screws 110 are passed through the screw holes (22u, 22u) and (22d, 22d) provided on the left and right sides of the upper narrow plate 20u and the lower narrow plate 20d, respectively, from the back side (see Figure 4(c)). Next, the screws 110 that have passed through at least the left and right screw holes (22u, 22u) of the upper narrow plate 20u are placed over the top of the mesh wires of the mesh section 54 and passed through the screw holes (12u, 12u) provided on the left and right sides of the top of the back plate 10B in the front direction. The screws 110 that pass through the left and right screw holes (22d, 22d) of the lower narrow plate 20d are similarly passed through the screw holes (12d, 12d) located on the left and right sides of the lower part of the back plate 10B, from the back side toward the front (see Figures 4(a), (b)). As a result, four screws 110 protrude from the top, bottom, left, and right sides of the back plate 10B, from the back side toward the front, and are then secured from the front side of the back plate 10B with wing nuts 111.

[0042] In the fire extinguisher holder 1 of this embodiment, the distance between the screw holes 12u and 12d provided at the top and bottom of the back plate 10B is 40 cm. Therefore, the screws 110 that pass through the upper screw hole 12u and the lower screw hole 12d are both supported on the upper part of the mesh wires of the mesh section 54. Accordingly, the fire extinguisher holder 1 of this embodiment can stably fix the back plate 10B to the mesh section 54 of the mesh frame 50 by the upper thin plate 20u and the lower thin plate 20d.

[0043] Furthermore, as shown in Figures 4(a) to (c), a gap of Δh = 5 cm or more is created between the bottom plate 10A protruding from below the back plate 10B of the fire extinguisher holder 1 and the floor. Since the head brush of a vacuum cleaner hose can be inserted into this gap, it is no longer necessary to move or lift the fire extinguisher holder each time cleaning is performed, as in the past, and cleaning can be carried out smoothly to maintain the cleanliness of stores and other establishments.

[0044] In this embodiment, for the sake of illustration, the mesh line spacing is set to 10 cm, the major axis of the elongated holes 14u and 14d is set to d=8 cm, the spacing between the elongated holes 14u and 14d is set to Δd=2 cm, and the spacing between the bottom plate 10A and the floor is set to Δh=5 cm. However, these lengths are not limited and can be changed as appropriate.

[0045] The fire extinguisher holder according to the present invention has been described above, but the present invention is not limited to the above embodiments and examples. Furthermore, the present invention can be implemented in various improved, modified, and altered forms based on the knowledge of those skilled in the art, without departing from the spirit of the invention. [Industrial applicability]
