[0004] [Patent Document 1] JP 2015-181558 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the bottom surface of the fire extinguisher installation stand is in sliding contact with the ground surface to prevent tipping over, the fire extinguisher may tip over if the fire extinguisher installation stand touches surrounding components. In addition, because the fire extinguisher installation stand is prone to moving, there is a possibility that it may come into contact with surrounding components that it should not touch.

[0006] In view of the above circumstances, one of the objects of the present invention is to provide a fire extinguisher holder that makes it more difficult for a fire extinguisher to tip over. Other objects can be understood from the following description and the explanation of the embodiment. [Means for solving the problem]

These numbers and symbols are added in parentheses for reference purposes to show an example of the correspondence between the description of the claims and the description of the embodiment of the invention. Therefore, the description in parentheses should not be interpreted as limiting the scope of the claims.

[0008] A fire extinguisher holder (1000) according to one embodiment for achieving the above object includes a mounting base (300), a case portion (100), and a hanging portion (200). A fire extinguisher (10) is mounted on the mounting base (300). The case portion (100) has an insertion hole (101) through which the fire extinguisher (10) is inserted in a first direction of the mounting base (300).

[Diagram 5] 2 is a cross-sectional view taken along line AA when a triangular cone is placed on a fire extinguisher holder in one embodiment. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] (Embodiment 1) The fire extinguisher holder 1000 in this embodiment will be described with reference to the drawings. The fire extinguisher holder 1000 includes a case part 100 having an insertion hole 101 through which the fire extinguisher 10 is inserted in a first direction (e.g., upward) as shown in FIG. 1. The case part 100 is formed so as to contact a placement surface on which the fire extinguisher holder 1000 is placed, for example, the ground. The fire extinguisher holder 1000 also includes a placement base 300 on which the fire extinguisher 10 is placed, and a hanging part 200 that connects the placement base 300 and the case part 100, as shown in FIG. The placement base 300 on which the fire extinguisher 10 is placed is hung from the upper part of the case part 100 by the hanging part 200 as shown in FIG. 3. Therefore, when a force is applied to the case part 100, for example, when the ground shakes or the case part 100 comes into contact with another member, the position of the mounting base 300 moves relative to the case part 100, reducing the change in the position of the center of gravity of the fire extinguisher holder 1000. This reduces the risk of the fire extinguisher 10 tipping over.

[0012] Here, for ease of understanding, a cylindrical coordinate system is used for explanation. The Z axis of the cylindrical coordinate system, for example, the +Z direction, represents the first direction, specifically the vertically upward direction when the fire extinguisher holder 1000 is placed. The -Z direction represents the opposite direction to the first direction. The Z axis of the cylindrical coordinate system passes through the geometric center in the cross section of the fire extinguisher holder 1000 by a plane perpendicular to the Z axis. The +R direction represents the outward direction in the radial direction of the cylindrical coordinate system, specifically the direction away from the Z axis among the in-plane directions of the plane perpendicular to the Z axis. The -R direction represents the inward direction in the radial direction, specifically the direction approaching the Z axis among the in-plane directions of the plane perpendicular to the Z axis. The θ direction represents the circumferential direction of the cylindrical coordinate system. Here, when either the upward or downward direction of the direction along the Z axis is acceptable, it is referred to as the Z direction. When either the outward or inward direction of the radial direction is acceptable, it is referred to as the R direction.

[0013] (Fire extinguisher holder structure) The structure of the fire extinguisher holder 1000 will be described. As described above, the fire extinguisher holder 1000 includes the case part 100, the hanging part 200, and the mounting base 300. The case part 100 includes, for example, a side part 110, a step part 120, and a ground part 130. The case part 100 is formed of any material, for example, polyethylene, soft polyethylene, ethylene-vinyl acetate copolymer resin (EVA), soft PVC, etc. The case part 100 may also be formed of a flame-retardant material, for example, metal (e.g., tinplate), flame-retardant plastic, etc. For example, the case part 100 has the shape of the lower side (the shape of the bottom side of the cone) when a triangular cone installed for the purpose of regulating roads, construction sites, etc. is cut along a plane perpendicular to the axis of the cone.

[0014] The side surface portion 110 forms an end portion in the +Z direction in the case portion 100, and is formed in a circular shape when viewed from the +Z direction, as shown in FIG. 2, for example. Specifically, the end of the side surface portion 110 in the +R direction is formed in a circular shape, and the end of the side surface portion 110 in the -R direction is also formed in a circular shape. Also, as shown in FIG. 3, the side surface portion 110 has a part of a cone side surface 410 that forms a side surface of a cone having an axis 400 extending in the Z axis. For example, the side surface portion 110 has a shape sandwiched between a first plane 430 and a second plane 440 that are perpendicular to the Z direction, among the cone side surface 410. Here, the first plane 430 and the second plane 440 are formed so that the apex 420 of the cone formed by the cone side surface 410 is not included between the first plane 430 and the second plane 440. Also, the apex 420 is not included in both the plane of the first plane 430 and the plane of the second plane 440. For example, the +Z end of the side surface portion 110 is formed in a circular ring shape within the plane of the first plane 430. An insertion hole 101 is formed at the +Z end of the side surface portion 110. In addition, the -Z end of the side surface portion 110 is formed in a circular ring shape within the plane of the second plane 440.

[0015] The step portion 120 is provided in the -Z direction of the side portion 110 and is connected to the -Z direction end of the side portion 110. As shown in Fig. 2, the step portion 120 is formed in an annular shape so as to surround the side portion 110 when viewed from the +Z direction. As shown in Fig. 3, the step portion 120 has an intermediate horizontal plate 121 having a plane perpendicular to the Z axis, and an intermediate vertical plate 122 protruding from the intermediate horizontal plate 121 in the -Z direction.

[0016] The intermediate horizontal plate 121 is formed in an annular shape, and is formed so that its -R end is connected to the -Z end of the side portion 110. The intermediate vertical plate 122 protruding in the -Z direction is connected to the +R end of the intermediate horizontal plate 121. The intermediate vertical plate 122 is formed in a cylindrical shape.

[0017] The grounding part 130 is connected to the end of the intermediate vertical plate 122 in the -Z direction, and forms the end of the case part 100 in the -Z direction. The grounding part 130 is formed so as to contact the arrangement surface, such as the ground or floor surface, on which the fire extinguisher holder 1000 is arranged. As shown in FIG. 2, for example, the grounding part 130 is formed in a rectangular shape so as to surround the step part 120 when viewed from the +Z direction. As shown in FIG. 3, the grounding part 130 includes a horizontal plate 131 having a plane perpendicular to the Z axis, an outer protruding part 132 protruding from the horizontal plate 131 in the -Z direction, and an inner protruding part 133.

[0018] The horizontal plate 131 is formed in an annular shape, and is formed so that the end in the -R direction is connected to the end in the -Z direction of the intermediate vertical plate 122 of the step portion 120. An outer protrusion 132 protruding in the -Z direction is connected to the end in the +R direction of the horizontal plate 131. In addition, an inner protrusion 133 protruding in the -Z direction is also connected to the end in the -R direction of the horizontal plate 131. The outer protrusion 132 and the inner protrusion 133 are formed in a cylindrical shape. The inner protrusion 133 is formed, for example, so that the intermediate vertical plate 122 extends in the -Z direction. In addition, when the fire extinguisher holder 1000 is placed, the end in the -Z direction of the outer protrusion 132 and the end in the -Z direction of the inner protrusion 133 are formed so that they come into contact with the placement surface, for example, the ground, floor surface, etc. For example, the end in the -Z direction of the grounding portion 130, specifically the end in the -Z direction of the outer protrusion 132 and the end in the -Z direction of the inner protrusion 133 may be formed in a plane perpendicular to the Z direction. For example, the length of the outer protrusion 132 in the Z direction is equal to the length of the inner protrusion 133 in the Z direction.

[0019] As shown in FIG. 3, the hanging part 200 includes a case joint part 210 joined to the upper part of the side part 110, a mounting base joint part 220 joined to the upper part of the mounting base 300, and a connection part 230 connecting the case joint part 210 and the mounting base joint part 220. The case joint part 210 may be formed integrally with the side part 110, or may be formed separately from the side part 110. A plurality of case joint parts 210, for example, three or more, are provided, and as shown in FIG. 2, they are provided at the end of the -R direction of the side part 110 at equal intervals in the θ direction. For example, when there are three case joint parts 210, they are provided at the end of the -R direction of the side part 110 at 120 degree intervals in the θ direction. When there are four case joint parts 210, they are provided at the end of the -R direction of the side part 110 at 90 degree intervals in the θ direction. The hanging part 200 is formed of any material. For example, the hanging portion 200 may be formed of a flame retardant material, such as a flame retardant plastic, metal, or the like chain.

[0020] As shown in FIG. 2, the mounting table joint 220 is joined to the end of the mounting table 300 in the +R direction, for example, within a range of several centimeters from the end in the +R direction. The mounting table joint 220 may be formed integrally with the mounting table 300, or may be formed separately from the mounting table 300. The mounting table joint 220 is provided to correspond to the case joint 210. For example, the direction from the corresponding case joint 210 toward the mounting table joint 220 represents the -R direction when viewed from the +Z direction. For example, the mounting table joint 220 is provided in the same θ direction as the corresponding case joint 210 and at a position in the -R direction from the corresponding case joint 210 when viewed from the +Z direction. Furthermore, when there are three case joints 210, three mounting table joints 220 are provided. When there are four case joints 210, four mounting table joints 220 are also provided.

[0021] As shown in FIG. 2, the connection part 230 is provided to connect the case joint part 210 and the mounting table joint part 220 corresponding to each other. For example, the connection part 230 is provided to extend in the -R direction from the case joint part 210 toward the corresponding mounting table joint part 220. The connection part 230 is formed, for example, in a freely bending string shape. For example, the connection part 230 includes a thread, a rope made of bundled threads, etc. In addition, the connection part 230 may be formed in a rod shape using a hard material that is difficult to bend, and connected to the case joint part 210 and the mounting table joint part 220 so that the angle between the Z axis and the connection part 230 can be freely changed. For example, the connection part 230 may be connected to the case joint part 210 and the mounting table joint part 220 so that the angle between the connection part 230 and the Z axis can be freely changed in both the R direction and the θ direction.

[0022] 3, the connection part 230 is formed to extend in the -Z direction from the case joint part 210 to the corresponding mounting base joint part 220 so as to suspend the mounting base 300. More specifically, the connection part 230 is formed to be inclined in the -R direction as it approaches the -Z direction. In addition, the length of the connection part 230 is adjusted so that the position of the mounting base 300, for example, the end in the -Z direction is located in the +Z direction from the end of the case part 100 in the -Z direction.

[0023] As shown in FIG. 2, the mounting table 300 is formed in a circular shape when viewed from the +Z direction. For example, the mounting table 300 is formed to be larger than the size of the bottom surface of the fire extinguisher 10 to be placed thereon when viewed from the +Z direction. For example, as shown in FIG. 3, the mounting table 300 includes a mounting portion 310 on which the fire extinguisher 10 is placed, and a frame portion 320 protruding from the mounting portion 310 in the +Z direction. The mounting portion 310 is formed in a plate shape, for example. For example, the mounting portion 310 is formed in a circular shape larger than the size of the bottom surface of the fire extinguisher 10 to be placed thereon when viewed from the +Z direction. The mounting table 300 may be formed of any material. For example, the mounting table 300 may be formed of a flame-retardant material, such as metal or flame-retardant plastic.

[0024] Frame portion 320 is formed so as to protrude in the +Z direction from the end of mounting portion 310 in the +R direction. Mounting table joint portion 220 is provided at the end of frame portion 320 in the +Z direction. Frame portion 320 may be formed integrally with mounting table joint portion 220, or may be formed as a separate body.

[0025] (Fire extinguisher holder function) As shown in FIG. 4, the fire extinguisher 10 is placed on the placement base 300 of the fire extinguisher holder 1000, specifically, on the placement portion 310. Therefore, the bottom surface 11 of the fire extinguisher 10 abuts against the placement portion 310 and is supported. In addition, a part of the side surface 12 of the fire extinguisher 10 may abut against the frame portion 320 of the placement base 300. When the fire extinguisher 10 is mounted on the placement portion 310, a force is applied to the placement portion 310 in the -Z direction. In addition, since the placement portion 310 is supported by the hanging portion 200, the force applied to the placement portion 310 applies a force in the -Z direction to the side portion 110 of the case portion 100 via the hanging portion 200. Since the case portion 100 is placed on the placement surface on which the fire extinguisher holder 1000 is placed, the case portion 100 maintains a state of being supported by the placement surface. In this manner, the fire extinguisher 10 is supported in a stable state by being placed on the placement base 300.

[0026] With the fire extinguisher 10 placed on the fire extinguisher holder 1000, assume that an external force, such as wind force or vibration, is applied to the fire extinguisher holder 1000. For example, assume that a force is applied to the fire extinguisher holder 1000 in the horizontal direction. In this case, when a horizontal force is applied, the case part 100 tries to move in response to the force. Meanwhile, since the mounting base 300 is suspended by the suspension part 200, it tries to stay in place due to inertial force. Therefore, the mounting base 300 tries to move in the opposite direction to the direction in which the external force is applied, relative to the case part 100. As a result, the fire extinguisher holder 1000 can be reduced from falling over.

[0027] Furthermore, the cross section of side surface portion 110 of fire extinguisher holder 1000 taken along a plane perpendicular to the Z direction forms a circular ring shape. Therefore, when a strong wind blows horizontally against fire extinguisher holder 1000, the wind flows along the surface of side surface portion 110 of fire extinguisher holder 1000, and side surface portion 110 disperses the force of the strong wind that fire extinguisher holder 1000 receives. This can reduce the risk of fire extinguisher holder 1000 tipping over.

[0028] For example, the case part 100 of the fire extinguisher holder 1000 has the shape of the lower side of a triangular cone. Therefore, when the fire extinguisher holder 1000 is moved to a work location, for example, a construction site, the fire extinguisher holder 1000 can be overlapped with the triangular cone 500 as shown in Fig. 5. For example, the triangular cone 500 is overlapped with the fire extinguisher holder 1000 so that the inner surface 511 of the cone side part 510, which is the cone part of the triangular cone 500, comes into contact with the outer surface of the side part 110 of the fire extinguisher holder 1000. Therefore, the space required for transporting the fire extinguisher holder 1000 is reduced.

[0029] In addition, by placing a cone weight on the cone grounding portion 530 that contacts the mounting surface, the tipping over of the triangular cone 500 is reduced. Since the case portion 100 of the fire extinguisher holder 1000 has the shape of the lower side of the triangular cone 500, the same cone weight can be used. This also reduces the space required to transport the member for reducing the tipping over of the fire extinguisher holder 1000.

[0030] (Modification)

[0031] The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be arbitrarily modified and / or combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the necessary functions can be realized.

[0032] For example, the case portion 100 may be formed in any shape so long as it is intended to reduce the risk of the fire extinguisher holder 1000 tipping over. For example, the side portion 110 may be formed in a cylindrical shape, or may have a part of a pyramidal side surface. The side portion 110 may also be formed in a rectangular tube shape.

[0033] The end of the side surface portion 110 in the +Z direction may be formed in an annular shape within a plane intersecting with a plane perpendicular to the Z axis. The end of the side surface portion 110 in the +Z direction may have a portion that is not included within the plane. For example, the end of the side surface portion 110 in the +Z direction may be formed in a wave shape.

[0034] The step portion 120 may be formed in a polygonal shape when viewed from the +Z direction. The step portion 120 may have a brace connecting the middle horizontal plate 121 and the middle vertical plate 122 for reinforcement. The middle vertical plate 122 of the step portion 120 may be omitted. For example, the horizontal plate 131 of the ground portion 130 may be connected to the end of the middle horizontal plate 121 in the -Z direction. The step portion 120 may be omitted, and the ground portion 130 may be directly connected to the side portion 110.

[0035] The grounding portion 130 may be formed in a circular ring shape or a polygonal shape when viewed from the +Z direction. In addition, the grounding portion 130 may have a brace connecting the horizontal plate 131 and the outer protrusion 132 for reinforcement. In addition, the outer protrusion 132 and the inner protrusion 133 of the grounding portion 130 may be omitted.

[0036] The -Z direction end of the grounding portion 130, for example, the -Z direction end of the outer protrusion 132 and the -Z direction end of the inner protrusion 133 may be formed within a plane intersecting a plane perpendicular to the Z direction. In this case, when the fire extinguisher holder 1000 is placed, the axis 400 (Z direction) of the side portion 110 is inclined with respect to the vertical direction.

[0037] Case joint 210 of hanging unit 200 may be joined at any position on side surface unit 110. For example, case joint 210 may be provided at the end of side surface unit 110 in the +Z direction, or at a position shifted in the -Z direction by several centimeters from the end of side surface unit 110 in the +Z direction. Case joint 210 may also be provided on side surface unit 110 at any interval in the θ direction.

[0038] Mounting base joint 220 of hanging section 200 may also be joined to mounting base 300 at any position.

[0039] Two connection parts 230 may be connected to one case joint part 210. Also, two connection parts 230 may be connected to one mounting table joint part 220.

[0040] The mounting base 300 may have any shape on which the fire extinguisher 10 can be mounted. For example, when viewed from the +Z direction, the size of the mounting base 300 may be larger than the insertion hole 101 through which the fire extinguisher 10 is inserted, or may be smaller than the insertion hole 101. Moreover, the size of the mounting base 300 may be the same as the insertion hole 101.

[0041] Mounting table 300 may be formed in a polygonal shape when viewed from the +Z direction. Furthermore, frame portion 320 of mounting table 300 may be omitted. In this case, mounting table joint portion 220 of hanging unit 200 is joined to mounting portion 310 either integrally or separately. [Explanation of symbols]
