Description

【Technical Field】 【0001】 The present invention relates to a gas cylinder fixing device for fixing a gas cylinder filled with LP gas such as propane gas. 【Background Art】 【0002】 In this specification, the gas cylinder means a large cylinder filled with LP gas such as propane gas, and does not mean a cassette cylinder used for a so-called cassette stove. Gas cylinders used in ordinary households are filled with liquefied petroleum gas such as propane. The head of this gas cylinder is dome-shaped, and a governor is installed there. Such gas cylinders are often installed in pairs. When the gas in the gas cylinder on the side in use runs out, it is switched to the gas cylinder on the side that has not been used, and the gas cylinder that has run out of gas is replaced. 【0003】 The gas cylinders used in this way are installed outdoors in a vertical state. To prevent them from accidentally falling over, a chain is hung on the hooks provided on both sides of the gas cylinder to surround the gas cylinder (Japanese Patent Laid-Open No. 10-00949 . The hooks are provided on the wall surface of the house or a dedicated support column. The type that surrounds the gas cylinder with this chain has a problem that the chain swayed by the wind contacts the gas cylinder and generates abnormal noise. To prevent the generation of such abnormal noise, there is also a type that uses a wide synthetic fiber belt instead of the chain (Japanese Patent Laid-Open No. 2005-083545). 【0004】 ​​​​​​​​​​​Furthermore, the applicant previously invented a gas cylinder fixing device, as described in Patent No. 7630867 (Patent Document 3). This gas cylinder fixing device comprised at least a mounting platform for placing gas cylinders side by side, a first locking hook fixedly provided on the mounting platform for locking the flange portion of the gas cylinder skirt from the inside, and a second locking hook detachably attached to the aforementioned mounting platform for locking the flange portion of the gas cylinder skirt from the inside, with the aforementioned mounting platform also provided with rails for sliding the gas cylinders when placing them. 【0005】 [Patent Document 1] Japanese Patent Application Publication No. 10-009495 [Patent Document 2] Japanese Patent Publication No. 2005-083545 [Patent Document 3] Patent No. 7630867 [Disclosure of the Invention] [Problems that the invention aims to solve] 【0006】 However, both chain-type and wide-belt-type systems will be affected by a strong earthquake. The chains and wide belts could no longer support the gas cylinder, causing it to break and tip over. There was a problem with that. Also, gas cylinders float in water, so if a flood or tsunami occurs, gas The gas cylinder can slip off the chain or wide belt and be released. In the worst case... The substance has also leaked out into the sea, causing problems for ship navigation. Furthermore, since chains and wide belts are fixed to the exterior walls of houses with bolts, etc., It can damage the house. Also, rainwater can seep into the exterior wall through holes such as bolts, causing deterioration of the house. It can sometimes be the cause. 【0007】 Furthermore, the gas cylinder fixing device described in Patent No. 7630867 required a rail-like section on the mounting base, resulting in a complex structure and cost issues. 【0008】 This invention was conceived in view of the above circumstances, and prevents gas cylinders from tipping over even during an earthquake. Without any hassle, and moreover, gas cylinder replacement work is easy, even in the event of floods or other water-related disasters. The objective is to provide a gas cylinder fixing device that does not leak, does not damage houses, and has a simplified mounting base that does not have a rail section like the gas cylinder fixing device of Patent No. 7630867, and is also cost-effective. [Means for solving the problem] 【0009】 The gas cylinder fixing device according to the present invention comprises a mounting base on which a gas cylinder is placed, and a locking hook that locks the flange portion of the skirt of the gas cylinder placed on the mounting base to fix the gas cylinder to the mounting base, the mounting base having a groove plate having a substantially U-shape and an overhanging portion that extends outward from the upper edge of a pair of opposing groove plate side walls, and a pair of base plates connected to the overhanging portion of the groove plate, the pair of base plates being connected to the groove plate with their edges protruding above the groove plate, and the locking hook having a first fixing plate having a hook portion that fits inside the flange portion of the skirt of the gas cylinder and locks the flange portion from the inside, The mounting base has a first fixing plate and a second fixing plate connected by bolts, the second fixing plate having a pair of opposing hook side walls that fit between a pair of groove plate side walls of the groove plate, the first fixing plate having through holes through which the bolts pass, and the second fixing plate having female threads that screw into the bolts, the locking hooks are fitted into the groove plate, and when the bolts are tightened with the hooks locked from the inside of the skirt of the gas cylinder placed on the groove plate of the mounting base, the hook side walls of the second fixing plate are pressed against the back surface of the edge of the base plate of the mounting base, thereby fixing it to the mounting base, and at the same time the gas cylinder is also fixed to the mounting base. 【0010】 Further, when placing a plurality of gas cylinders on the mounting table, the locking hook of the gas cylinder fixing device according to the present invention includes a central locking hook that is one less than the number of gas cylinders for locking two gas cylinders, and two outer locking hooks for locking one gas cylinder. Two hook portions are formed on the first fixing plate of the central locking hook, and one hook portion is formed on the first fixing plate of the outer locking hook. 【0011】 On the other edges of the pair of substrates except for the edge protruding above the groove plate, vertical wall portions corresponding to the thickness dimension of the groove plate are formed. 【0012】 A coil spring interposed between the first fixing plate and the second fixing plate is fitted on the leg portion of the bolt. 【0013】 The first fixing plate of the central locking hook and the first fixing plate of the outer locking hook are the same. 【Advantages of the Invention】 【0014】 The gas cylinder fixing device according to the present invention fixes the gas cylinder placed on the mounting table by a locking hook that fits into the groove plate of the mounting table. Therefore, it is not necessary to configure a rail portion or the like on the mounting table as in the conventional gas cylinder fixing device of this type. Since the rail portion and the like are omitted, the gas cylinder can be placed on the mounting table from any direction, making the replacement work of the gas cylinder easier. Since the rail portion and the like are unnecessary, the configuration of the mounting table is simplified and cost reduction can be achieved. 【0015】 Also, with this gas cylinder fixing device, even if there is an earthquake, the gas cylinder will not fall over, and the replacement work of the gas cylinder is easy. Even if a flood or other water damage occurs, the gas cylinder will not flow out and will not damage the house. 【Brief Description of the Drawings】 【0016】 [Figure 1]It is a schematic perspective view of a mounting plate constituting a gas cylinder fixing device according to an embodiment of the present invention and a locking hook in a disassembled state.

The device comprises fixing plates 210A and 210B, and second fixing plates 220A and 220B which are connected to the first fixing plates 210A and 210B by bolts 230A and 230B and have a pair of opposing hook side walls 221A and 221B that fit between a pair of groove plate side walls 111 of the groove plate 110. The first fixing plates 210A and 210B have through holes 212A and 212B through which the bolts 230A and 230B pass, and the second fixing plates 220A and 220B have female threaded portions 222A and 222B that screw into the bolts 230A and 230B. With opening B, the two locking hooks 200A and 200B are fitted into the groove plate 110, and when the bolts 230A and 230B are tightened with the hook portions 211A and 211B locked from the inside of the skirt GB2 of the gas cylinder GB placed on the groove plate 110 of the mounting base 100, the hook side walls 221A and 221B of the second fixing plates 220A and 220B are pressed against the back surface of the edge portion 121 of the base plate 120 of the mounting base 100, thereby fixing them to the mounting base 100, and at the same time fixing the gas cylinder GB to the mounting base 100. 【0018】 First, before explaining the gas cylinder fixing device 1000A, we will explain the gas cylinder GB that will be fixed to this gas cylinder fixing device 1000A, referring to Figure 9. Gas cylinders GB are generally formed by welding molded steel plates or aluminum. Such a gas cylinder GB has a cylindrical body GB1, a skirt GB2 provided at the lower end of the body GB1 for self-support, a neck GB4 at the upper end of the body GB1, and a protector GB5 attached to the body GB1 so as to cover the neck GB4. The lowest end of the skirt GB2 is a flange portion GB3 that is curved inward. Furthermore, the skirt GB2 is provided with an air vent (not shown) to prevent corrosion. There are no specific regulations regarding the shape of this vent, and it varies from manufacturer to manufacturer. The GB gas cylinder comes in three different capacities: a 10kg type with a height of approximately 520mm, a 20kg type with a height of approximately 990mm, and a 50kg type with a height of approximately 1410-1440mm. The 1000A gas cylinder fixing device is compatible with all of the GB gas cylinders. 【0019】 The mounting base 100A has a width that allows two gas cylinders GB to be installed side by side. The grooved plate 110 and the pair of substrates 120 that make up this mounting base 100 are formed by bending the ends of rectangular metal plates in plan view, which have been treated with corrosion prevention measures such as plating or painting. First, as shown in Figures 1 and 2, the groove plate 110 has a roughly U-shaped configuration with a pair of opposing groove plate side walls 111 and an outwardly protruding portion 112 at the upper edge, forming a roughly trough-like shape overall, and a roughly U-shaped configuration when viewed from the front. The height dimension of the groove side walls 111 is set to be slightly smaller than the thickness dimension of the central locking hook 100A and the outer locking hook 100B, which will be described later. More specifically, when both locking hooks 100A and 100B are fitted into the groove plate 110, the hook portions 211A and 211B of both locking hooks 200A and 200B are positioned higher than the edge portion 112 of the groove plate 110. Furthermore, the protruding portion 112 of this groove plate 110 has an opening 113 that corresponds to the connecting screws 130 described later. 【0020】 On the other hand, as shown in Figures 1 and 2, the pair of substrates 120 are rectangular in plan view and have the same length as the groove plate 110, and vertical wall portions 124 and 125 corresponding to the thickness of the groove plate 110 are formed on the other edges 122 and 123, excluding the edge portion 121 that protrudes above the groove plate 110. Therefore, when the pair of substrates 120 are connected to the groove plate 110, the bottom surface of the groove plate 110 and the vertical wall portions 124 and 125 of the substrates 120 become flush. As shown in Figure 2, the pair of substrates 120 have multiple openings 126 (a total of eight in the drawing) on ​​their edges 121, corresponding to the openings 113. These openings 126 and the openings 113 are located in corresponding positions, and the pair of substrates 120 are connected to the protruding portion 122 of the groove plate 110 by fastening both openings 126 and 133 with multiple connecting screws 130 (a total of eight in the drawing). In this case, the edges 121 of the pair of substrates 120 protrude above the groove plate 110. 【0021】 Furthermore, a total of six bolt holes 127 are provided, three each at the corners where the edges 122 and 123 of the pair of substrates 120 intersect, and near the center of the edge 122, for fixing the mounting base 100. The mounting base 100, which consists of a groove plate 110 and a pair of base plates 120, is fixed to a flat concrete surface or the like that is pre-formed at the installation location by bolts (not shown) that pass through the bolt holes 127. 【0022】 As shown in Figure 3, the outer locking hook 200B consists of a first fixing plate 210B having a hook portion 211B, a second fixing plate 220B connected to the first fixing plate 210B by a bolt 230B and having a pair of opposing hook side wall portions 221B that fit between a pair of groove plate side wall portions 111 of the groove plate 110, a bolt 230B connecting the first fixing plate 210B and the second fixing plate 220B, and a coil spring 250B fitted into the leg portion of the bolt 230B and interposed between the first fixing plate 210B and the second fixing plate 220B. 【0023】 As shown in Figures 3 and 4, the first fixing plate 210B has a flat surface 215B that is approximately rectangular in plan view, and a hook portion 211B is bent and formed from one side of this flat surface 215B. This hook portion 211B is the part that locks the flange portion GB3 of the skirt GB2 of the gas cylinder GB from the inside. Furthermore, of the four sides of the flat surface 215B of the first fixing plate 210B, the three sides other than the side on which the hook portion 211B is formed have bent edges 213B that are bent on the opposite side from the hook portion 211B. 【0024】 Furthermore, a through hole 212B is provided in the flat surface 215B of the first fixing plate 210B. This through hole 212B is the portion through which the bolt 230B, which will be described later, passes. The width dimension of this first fixing plate 210B is set to fit into the pair of hook side wall portions 221B of the second fixing plate 220B, which will be described later. 【0025】 As shown in Figures 3 and 5, the second fixing plate 220B has a flat surface 225B that is approximately rectangular in plan view, and hook side walls 221B are formed by bending from two opposing sides of this flat surface 225B. The distance between the outer surfaces of the opposing pair of hook sidewalls 221B is set to be slightly smaller than the distance between the inner surfaces of the opposing pair of groove plate sidewalls 111 of the groove plate 110. As a result, the first fixing plate 210B can fit inside the second fixing plate 220B. Furthermore, the height dimension of the hook side wall portion 221B is set to be smaller than the height dimension of the groove plate side wall portion 111. Furthermore, the flat surface 225B has a female threaded portion 222B into which a bolt 230B is screwed. 【0026】 The external locking hook 200B is constructed by combining the first fixing plate 210B and the second fixing plate 220B, which are configured as described above. More specifically, the first fixing plate 210B and the second fixing plate 220B are assembled such that the through hole 212B of the first fixing plate 210B and the female threaded portion 222B of the second fixing plate 220B are located on the same perpendicular line, and a coil spring 250B is interposed between the through hole 212B and the female threaded portion 222B. The assembly is formed by screwing a bolt 230B into the female threaded portion 222B via the through hole 212B. Since the legs of the bolt 230B fit into the legs of the coil spring 250B, the first fixing plate 210B and the second fixing plate 220B, which are connected by the bolt 230B, are subjected to a force that separates them due to the coil spring 250B. 【0027】 Furthermore, the central locking hook 200A consists of a first fixing plate 210A, a second fixing plate 220A, a bolt 230A connecting both fixing plates 210A and 210B, and a coil spring 250A that fits into the leg of the bolt 230A. 【0028】 The second fixing plate 220A of the central locking hook 200A is exactly the same as the second fixing plate 220B of the outer locking hook 200B, so its description will be omitted. Furthermore, since the second fixing plate 220A of the central locking hook 200A is the same as the second locking plate 220B of the outer locking hook 200B, a different second fixing plate is not required, thus reducing costs without increasing the overall number of parts. 【0029】 As shown in Figure 6, the first fixing plate 210A is formed to be longer than the first fixing plate 210B of the outer locking hook 200B. This is to secure two adjacent gas cylinders GB simultaneously. The first fixing plate 210A is formed in a rectangular shape in plan view, with one hook portion 211A formed on each of the opposing short sides of the flat surface 215A. Of the four sides of the flat surface 215A of the first fixing plate 210A, two sides other than the side on which the hook portion 211A is bent have bent edges 213A formed on the side opposite to the hook portion 211A. The shape of the hook portion 211A itself is set to be the same as the shape of the hook portion 211B of the outer locking hook 200B. Furthermore, a through hole 212A into which a bolt 230A is screwed is provided in the center of the flat surface 215A. The width dimension of this first fixing plate 210A is set to fit into the pair of hook side wall portions 221A of the second fixing plate 220A, which will be described later. 【0030】 Next, the procedure for securing the two gas cylinders GB onto the mounting base 100 using the one central locking hook 200A (one less than the number of gas cylinders GB) and the two outer locking hooks 200B configured in this way will be explained. First, the central locking hook 200A and the outer locking hook 200B are fitted into the groove plate 110. At this time, the central locking hook 200A is positioned approximately in the center of the mounting base 100, and the outer locking hook 200B is positioned a distance from the central locking hook 200A equal to the diameter of the gas cylinder GB. 【0031】 The two gas cylinders GB are placed on the mounting base 100, and the hook portion 211A of the central locking hook 200A is fitted from the inside onto the flange portion GB3 of the skirt GB2 of the gas cylinder GB. Furthermore, the hook portions 220B of the two outer locking hooks 200B are designed to fit from the inside into the flange portion GB3 of the skirt GB2 of the gas cylinder GB. Initially, the hook-shaped side walls 221A and 221B of the second fixing plates 220A and 220B do not come into contact with the back surface of the edge 121 of the substrate 120 of the mounting base 100, as shown in Figure 7(A). 【0032】 In this state, bolts 230A and 230B are tightened. As a result, the first fixing plates 210A and 210B are displaced downward, and the second fixing plates 220A and 220B are displaced upward, while the coil springs 250A and 250B are compressed. The hook portions 211A and 211B of the first fixing plates 210A and 210B engage with the flange portion GB3 of the skirt GB2 of the gas cylinder GB from the inside, and the hook side walls 221A and 221B of the second fixing plates 220A and 220B are pressed against the edge portion 121 of the base plate 120 from the back (see Figure 7(B)). This secures the gas cylinder GB on the mounting base 100. Note that while Figure 7 shows the relationship between the central locking hook 200A and the gas cylinder GB, the relationship between the outer locking hook 200B and the gas cylinder GB is the same. 【0033】 Since the central locking hook 200A and the outer locking hook 200B are not fixed to the mounting base 100, they can accommodate gas cylinders GB of different dimensions. Furthermore, since there are no protrusions on the upper surface of the mounting base 100, the gas cylinder GB can be placed on the mounting base 100 from any direction. For this reason, this gas cylinder fixing device 1000 offers excellent work efficiency in the replacement of gas cylinder GB. Furthermore, since the central locking hook 200A and the outer locking hook 200B are not screwed to the mounting base 100 like conventional gas cylinder fixing devices of this type, even if the connection between the bolts 230A and 230B and the female threaded parts 222A and 222B loosens due to repeated use, only the central locking hook 200A and the outer locking hook 200B need to be replaced, and the mounting base 100 itself does not need to be replaced, making it economical. 【0034】 The gas cylinder fixing device according to the above-described embodiment is used to fix two gas cylinders GB, but the present invention is not limited to this. It can be a type that secures one gas cylinder GB, or a type that secures three or more gas cylinder GBs. If only one gas cylinder GB is to be secured, the central locking hook 200A is not necessary, and the gas cylinder GB can be secured from the left and right using the two outer locking hooks 200B. Furthermore, when securing three or more gas cylinders GB, use two outer central locking hooks 200B and one less central locking hook 200A than the number of gas cylinders GB.
