Description

[Technical Field]

[0001] The present invention relates to a storage device for a respirator and a method for using the storage device for a respirator. In particular, the present invention relates to a storage device for air respirators that can quickly adjust the shape and position of a pressing member to match the size and shape of an air cylinder even when no cushioning material is used, and that can stably fix and support the air cylinder, and to a method for using such a storage device for air respirators. [Background technology]

[0002] In general, emergency vehicles such as fire engines are equipped with so-called breathing apparatuses for use in firefighting activities when a fire breaks out and emergency and life-saving activities in the event of a disaster, etc. Breathing apparatuses consist of an air cylinder, accessories such as an air tube and regulator connected to the air cylinder, an intake mask, and other equipment including a back support for attaching the air cylinder to the back, and are stored in the space behind the seat of a fire engine, etc.

[0003] Conventionally, as a storage device for such an air breathing apparatus, a backpack-mounted cylinder storage device for use in an emergency vehicle has been proposed (see Patent Document 1). More specifically, the cylinder storage device has a box-shaped storage space for the cylinder, a slidable cylinder holder inside, and the air respirator is stored in the storage space by being placed on the cylinder holder together with accessories such as a regulator. When in use, the cylinder holder is advanced forward and the air cylinder is removed together with the equipment.

[0004] Also, a mounting structure for breathing apparatus in a fire engine has been proposed (see Patent Document 2). More specifically, the respirator is detachably installed on a stepped portion of the space formed behind the seat, and the respirator is configured to function as a backrest (seat back), and the backrest of the cylinder can be used to lean against when seated, so that the respirator can be quickly put on even in an emergency.

[0005] Furthermore, a storage device for breathing apparatuses has been proposed that can move breathing apparatuses that are normally kept inside emergency vehicles such as fire engines while being fixed and supported, and that does not hinder the movement of the breathing apparatuses when they are moved (Patent Document 3). More specifically, it comprises a cylinder holding member that contacts the side of the air cylinder, a main frame to which they are attached, and a pressure plate that is rotatably installed above the main frame and has a pressing part that contacts the top of the air cylinder. When the pressure plate is rotated forward, it is in a fixed position to hold the air cylinder, and when rotated backward, it is in a retracted position to allow the air cylinder to be removed. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2003-70924 A (Claims, etc.) [Patent Document 2] Japanese Utility Model Application Publication No. 2-45766 (Claims, etc.) [Patent Document 3] Patent No. 6352795 (Claims, etc.) DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0007] However, the storage device for respirators described in Patent Document 1 is configured to store the respirators inside a box-shaped storage section, and therefore has a complex structure, requiring a slidable cylinder holding stand to move the respirators forward. In other words, because the air respirator itself is slid, the surrounding frame and the cylinder holding stand cannot be stably fixed, resulting in a problem of low stability when the air respirator is supported. Furthermore, when using the respirator, it is necessary to first open the front door and then move the respirator together with the holder forward, which makes it difficult for the user to quickly put on the respirator.

[0008] Furthermore, the mounting structure for the air respirator described in Patent Document 2 uses a mounting belt and mounting brackets to secure the cylinder inside the vehicle. Therefore, there was a problem that the mounting belt and mounting brackets were prone to loosening due to play, and the stability when supporting the air respirator was low. Furthermore, when carrying the respirator on one's back while seated, it is necessary to remove the mounting belt and mounting bracket, which may hinder operation in an emergency. Therefore, in response to the recent demand for lighter air cylinders, there are now many different cylinder materials and shapes, and there is a need for a storage device that can accommodate a wide variety of cylinders.

[0009] Furthermore, the air respirator storage device described in Patent Document 3 aims to make it easy and quick to remove the air cylinder by rotating the pressing plate, but does not have a mechanism for maintaining the horizontality of the pressing member, and the operability when attaching the air cylinder is insufficient. Furthermore, since it does not have a predetermined cylinder holding member, it does not provide sufficient cushioning when the air cylinder comes into contact with it. Therefore, a cushioning material or the like is required to essentially fill the gap between the cylinder holding member in the storage device and the air cylinder, and it can take time to adjust the settings to suit the size and shape of the air cylinder.

[0010] The present invention has been made in view of the above circumstances, and aims to provide a storage device for respirators that can be quickly adjusted to fit the size and shape of the air cylinder used in respirators kept inside emergency vehicles such as fire engines, and that can stably fix and support various types of air cylinders, as well as a method for using the same. [Means for solving the problem]

[0011] According to the present invention, a storage device for an air respirator for storing an air cylinder in an upright position comprises a cylinder holding member that abuts against the side of the air cylinder, a main frame to which the cylinder holding member is attached, and a pressing member provided above the main frame in the vertical direction with a pressing portion that contacts the top of the air cylinder, and the cylinder holding member is a U-shaped plate-like member that is provided in the cylinder holding member and moves back and forth along a long hole that extends horizontally relative to the main frame to adjust the sliding length. In other words, according to the storage device for air respirators of the present invention, even if no cushioning material is used, the mechanism by which the cylinder holding member slides back and forth can adequately absorb the impact when the air cylinder comes into contact with it. Furthermore, the slide length of the cylinder holding member can be adjusted according to the size and shape of the air cylinder, and the position and height can be quickly adjusted, allowing the air cylinder to be stably fixed and supported.

[0012] Furthermore, in constructing the present invention, it is preferable that the cylinder holding member has at least a two-layer structure consisting of a movable plate that moves back and forth relative to the main frame, and a fixed plate that is fixed to the main frame and arranged along the surface of the movable plate. With this configuration, the fixed plate can be used as a guide to quickly and accurately adjust the slide length of the movable plate, thereby more stably fixing and supporting the air cylinder.

[0013] Furthermore, in constructing the present invention, it is preferable that the cylinder holding member has a laminated structure including a movable plate that moves back and forth relative to the main frame, a first fixed plate that is fixed to the main frame and arranged along the lower surface of the movable plate, and a second fixed plate that is fixed to the main frame and arranged along the upper surface of the movable plate. With this configuration, the sliding length of the movable plate can be adjusted quickly and accurately using the upper and lower fixed plates as guides, thereby more stably fixing and supporting the air cylinder.

[0014] In configuring the present invention, it is preferable that at least two cylinder holding members are provided, in order from above along the vertical direction, namely, a first cylinder holding member and a second cylinder holding member. With this configuration, the side of the air cylinder can be fixed at two different points, and the attitude of the supported air cylinder can be controlled with greater precision.

[0015] In addition, in configuring the present invention, it is preferable that the sliding length of the second cylinder holding member is longer than the sliding length of the first cylinder holding member. With this configuration, even when the air cylinder is tilted backward relative to the main frame, the cylinder holding member can be efficiently abutted against the air cylinder, thereby supporting the air cylinder more stably.

[0016] Furthermore, when configuring the present invention, in the case where the cylinder holding member is provided with a plurality of replacement members each having at least a different U-shaped arc, it is preferable that when an air cylinder is placed on the main frame, a replacement member is selected and used based on the shape and size of the air cylinder placed on the main frame. With this configuration, a cylinder holding member of an appropriate shape can be used for each type of air cylinder, and by fitting it to the arc, the gap between the cylinder holding member and the air cylinder can be reduced, allowing the air cylinder to be supported more stably.

[0017] Furthermore, when the pressure member consists of two vertical pieces extending forward from the left and right side surfaces of the main frame and a horizontal piece connecting the upper front sides of the vertical pieces, it is preferable that a stopper be provided at one end of the vertical piece to regulate the rotation angle of the pressure member. This configuration makes it possible to more efficiently prevent the retainer from rotating further downward than the horizontal position in which it is fixed when lowered. As a result, it is no longer necessary to hold down the retainer with one hand when attaching an air cylinder, making it quicker and easier to attach the air cylinder.

[0018] Another aspect of the present invention is a method for using the above-mentioned storage device for respirators, which method includes the following steps (1) to (5): (1) A process for placing an air cylinder on a main frame in an air respirator. (2) A step of moving the cylinder holding member to abut against the side of the air cylinder. (3) A process of abutting the pressing member against the top of the air cylinder and fixing the air cylinder with the cylinder holding member and the pressing member. (4) A step of removing the holding member from the air cylinder to release the air cylinder from its fixed position. (5) The process of removing the air cylinder from the main frame. In this way, by implementing the method of using the storage device for the air respirator, even if no cushioning material is used, the mechanism that allows the cylinder holding member to slide back and forth can adequately absorb the impact when the air cylinder comes into contact. Furthermore, the size and position of the presser can be quickly adjusted to match the size and shape of the air cylinder, allowing the air cylinder to be stably fixed and supported.

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate. In addition, in each drawing used for the explanation, the same components are denoted by the same reference numerals, and the explanation thereof may be omitted. The drawings used in the description are only schematic illustrations to the extent that the invention can be understood, and the devices, shapes, dimensions, materials, etc. used in the description are merely preferred examples within the scope of the invention. Therefore, the present invention is not limited to the following embodiments without any particular reason.

[0021] [First embodiment] As shown in FIG. 1, the storage device for air respirators of the first embodiment is a storage device 10 for air respirators that stores an air cylinder (not shown) in an upright position, and includes a cylinder holding member 22 that abuts against the side of the air cylinder, a main frame 12 to which the cylinder holding member 22 is attached, and a pressing member 14 above the main frame 12 that has a pressing portion 16 that contacts the top of the air cylinder. The cylinder holding member 22 is a U-shaped plate-like member that moves back and forth relative to the main frame 12 along an elongated hole provided in the cylinder holding member 22.

[0022] 1. Main frame The main frame is basically a housing that is arranged around the air cylinder in the air respirator described below, and to which at least the cylinder holding member and the pressing member are attached. Specifically, as shown in FIG. 2, the main frame 12 preferably has a pair of left and right mounting pieces 12a protruding forward on the upper side of the main frame, and another pair of left and right mounting pieces 12b on the lower side. Furthermore, it is preferable that a vertical piece 14b of a pressing member 14 (described later) is axially supported on the upper mounting piece 12a by a bolt, nut, or the like, so that the pressing member 14 can rotate relative to the main frame 12. The reason for this is that with this configuration, after the air respirator is placed in the storage area surrounded by the main frame, the presser member can be rotated to more quickly fix and support the air cylinder.

[0023] The main frame preferably includes a plate-shaped member, a pipe-shaped member, a rectangular column-shaped member, a lattice-shaped member, a punched plate, or the like. The reason for this is that by using such components, it is easy to process the main frame to provide screw holes, through holes, etc. at accurate positions, and the supported air cylinder can be stably held down by cylinder holding members or pressing members fixed to the main frame. Therefore, it is preferable that the air filter be arranged so as to surround at least the left and right sides and the rear of the air cylinder.

[0024] Furthermore, the material of the main frame is not particularly limited as long as it has the strength to stably fix and support the air cylinder, but it is usually preferable to use aluminum, iron, carbon steel, stainless steel, polycarbonate resin, carbon fiber reinforced plastic, etc. The reason for this is that the use of such materials increases the strength, making it less likely to break or deform even if it is hit by an air cylinder or the like. Therefore, it is particularly preferable to use aluminum as the material for the main frame because of its excellent workability and light weight.

[0025] The vertical height of the main frame is preferably set to the height of the air cylinder to be fixed and supported, and is usually preferably set to a value within the range of 200 to 800 mm. The reason for this is that such a height allows it to be used universally for various air cylinders, regardless of region, etc. Therefore, it is more preferable that the height of the main frame is generally set to a value within the range of 300 to 750 mm, and even more preferable that it be set to a value within the range of 400 to 700 mm.

[0026] Furthermore, it is preferable that the width and depth of the main frame be adjusted to match the width of the air cylinder to be fixed and supported and the width of the chair on which it will be installed, and generally, values ​​within the range of 150 to 500 mm are preferred, values ​​within the range of 200 to 450 mm are more preferred, and values ​​within the range of 250 to 400 mm are even more preferred. The reason for this is that such a size allows for greater flexibility in placement on the fire engine.

[0027] 2. Cylinder holding member The cylinder holding member is a plate-like member that moves back and forth relative to the main frame and abuts against the side of the air cylinder to securely support the air cylinder. When viewed in a plane, it has a U-shaped portion (sometimes called an arc-shaped portion) that forms a predetermined area along the side of the supported air cylinder and extends toward the inside of the plate-like member. That is, the cylinder holding member is a member that moves the U-shaped portion against the air cylinder placed on the main frame, thereby supporting the air cylinder so that it does not shift rearward or sideways. Specifically, as shown in FIG. 2, it is preferable that the cylinder holding member 22 has an elongated hole 23c extending along the vertical direction, and is screwed through the elongated hole 23c into a screw hole 13c provided in the main frame 12. The reason for this is that by being screwed in through the long hole in this manner, the height of the cylinder holding member can be adjusted more quickly to match the size and shape of the air cylinder.

[0028] Furthermore, the material of the cylinder holding member is not particularly limited as long as it has the strength to stably fix and support the air cylinder, but it is usually preferable to use aluminum, iron, carbon steel, stainless steel, polycarbonate resin, carbon fiber reinforced plastic, etc. The reason for this is that the use of such materials increases the strength, making it less likely to break or deform even if it is hit by an air cylinder or the like. Therefore, it is particularly preferable to use aluminum as the material for the main frame because of its excellent workability and light weight.

[0029] Furthermore, as shown in Figure 3(a), when viewed in a plane, the length L1 of the U-shaped portion 24 along the front-to-back direction is preferably adjusted according to the size of the air cylinder, but is usually preferably set to a value within the range of 50 to 200 mm. The reason for this is that such a length allows the air cylinder to be inserted deep into the cylinder holding member, making it possible to more stably fix and support the air cylinder. Therefore, the length L1 of the U-shaped portion along the front-rear direction is preferably set to a value within the range of 60 to 180 mm, and more preferably to a value within the range of 70 to 150 mm.

[0030] Furthermore, as shown in Figure 3(a), when viewed in a plane, the width W1 of the U-shaped portion 24 along the vertical direction is preferably adjusted according to the size of the air cylinder, but is usually preferably set to a value within the range of 50 to 300 mm. The reason for this is that by using such a width, it is possible to prepare replacement cylinder holding members with different arcs to suit various types of air cylinders. Therefore, it is more preferable that the width W1 of the U-shaped portion is generally set to a value within the range of 100 to 280 mm, and even more preferable that it be set to a value within the range of 150 to 250 mm.

[0031] As shown in FIG. 3(b), it is generally preferable that the slide length M1 of the cylinder holding member is set to a value within the range of 5 to 150 mm. The reason for this is that by using such a slide length, the position can be flexibly adjusted and various air cylinders can be fixed and supported more stably. Therefore, it is more preferable that the slide length M1 of the cylinder holding member is set to a value within the range of 8 to 120 mm, and even more preferable that it is set to a value within the range of 10 to 100 mm.

[0032] The thickness of the cylinder holding member along the vertical direction is preferably set in accordance with the size of the air cylinder, and is usually preferably set to a value within the range of 1 to 15 mm. The reason for this is that by making the thickness this way, even if the air cylinder is hit, it can absorb the impact appropriately, preventing damage or deformation, etc., and allowing the air cylinder to be fixed and supported more stably. Therefore, it is more preferable that the thickness of the plate-like member is generally set to a value within the range of 3 to 12 mm, and even more preferable that it is set to a value within the range of 5 to 10 mm.

[0033] Furthermore, it is preferable that the planar shape of the U-shaped portion is a circular arc, an elliptical arc, a triangle, a rectangle, a trapezoid, or a polygon (for example, a pentagon to a dodecagon). The reason for this is that by using this shape, the ends of the cylinder holding member can be abutted at multiple points along the side of the air cylinder, allowing the air cylinder to be fixed and supported more stably. Therefore, it is particularly preferable that the planar shape of the U-shaped portion be an arc shape.

[0034] Here, the U-shape is sufficient as long as it follows the side surface of the air cylinder to some extent when viewed from above, and it is generally preferable to set the value of L1 / W1 within the range of 0.2 to 2. The reason for this is that by setting such a value, the cylinder holding member can be brought into contact with the air cylinder over a wide area, and the air cylinder can be fixed and supported more stably. Therefore, it is more preferable to set the value of L1 / W1 within the range of 0.3 to 1.5, and even more preferable to set it within the range of 0.4 to 1.

[0035] As shown in FIGS. 3(a) and 3(b), the cylinder holding member 22 preferably has a guide member 23d on at least one of the widthwise side surfaces for guiding the sliding of the movable plate 22a. The reason for this is that such a configuration allows the movable plate to slide stably without being displaced in the width direction. Therefore, from the viewpoint of facilitating adjustment of the angle of the guide member, etc., it is preferable that the guide member be provided on at least one of the widthwise sides of the first fixed plate and the second fixed plate, and it is even more preferable that the guide member be provided on both widthwise sides.

[0036] As shown in FIGS. 4(c) to 4(d), it is preferable that the end of the U-shaped portion 24 is rounded. The reason for this is that by processing in this way, the U-shaped portion can be brought into contact more effectively regardless of the angle of the air cylinder.

[0037] As shown in FIG. 4(d), the end of the U-shaped portion preferably has a protective layer 22d. The reason for this is that the protective layer smooths out any unevenness at the end of the U-shaped portion, reducing the gap between the cylinder holding member and the air cylinder, allowing the air cylinder to be fixed and supported more stably. Specifically, it is preferable that the end of the U-shaped portion is painted with urethane paint, epoxy paint, acrylic paint or the like.

[0038] It is also preferable that the cylinder holding member has a two-layer structure having a fixed plate fixed to the main frame and a movable plate that moves back and forth relative to the main frame along the surface of the fixed plate. The reason for this is that by configuring it in this way, the fixed plate can be used as a guide, allowing the movable plate to slide quickly and accurately, and the air cylinder can be fixed and supported more stably.

[0039] More specifically, as shown in FIG. 2, it is preferable that the cylinder holding member 22 has a three-layer structure having a movable plate 22a that moves back and forth relative to the main frame 12, a first fixed plate 22b that is fixed to the main frame 12 and arranged along the lower surface of the movable plate 22a, and a second fixed plate 22c that is fixed to the main frame 12 and arranged along the upper surface of the movable plate 22a. The reason for this is that by positioning the movable plate sandwiched between two fixed plates in this way, vertical shaking can be reduced when the movable plate is slid, allowing the air cylinder to be fixed and supported more accurately.

[0040] Furthermore, as shown in FIG. 1, when the cylinder holding member 22 is a first cylinder holding member 22', it is preferable that a second cylinder holding member 22'' is provided below the first cylinder holding member 22' along the vertical direction of the main frame. The reason for this is that by providing multiple cylinder holding members in this manner, the side of the air cylinder can be fixed at two different points, allowing the posture of the supported air cylinder to be controlled with precision, and the air cylinder can be fixed and supported more stably.

[0041] More specifically, when the cylinder holding member has a first cylinder holding member and a second cylinder holding member, if the height of the first cylinder holding member is HA (mm) and the height of the second cylinder holding member is HB (mm), it is preferable that HB is 3 / 4 x HA or less. The reason for this is that by arranging the cylinder holding member in this manner, the attitude of the supported air cylinder can be controlled with high precision, and the air cylinder can be fixed and supported more stably. Therefore, it is more preferable to set HB to 2 / 3×HA or less, and even more preferable to set HB to 1 / 2×HA or less.

[0042] It is also preferable that the sliding length of the second cylinder holding member is longer than the sliding length of the first cylinder holding member. The reason for this is that by providing the second cylinder holding member in this manner, the air cylinder can be supported in a forward tilted position, allowing the air cylinder to be removed more quickly when using the air respirator.

[0043] Furthermore, it is preferable that the cylinder holding member is provided with a plurality of replacement members each having at least a different U-shaped arc, and when an air cylinder is placed on the main frame, a replacement member is selected and used based on the shape and size of the air cylinder placed thereon. The reason for this is that a cylinder holding member of an appropriate shape can be used for each type of air cylinder, and by fitting it to the arc, the gap between the cylinder holding member and the air cylinder can be reduced, allowing the air cylinder to be supported more stably. More specifically, as an example, as shown in FIG. 5(a), it is preferable to prepare an exchange member 22x having a small arc 24x to fit a small air cylinder that is easy for even women to use. On the other hand, as an example, it is preferable to prepare an exchange member 22y having a large arc 24y in accordance with a large air cylinder or the like that can supply air for a long period of time.

[0044] 3. Presser member The pressing member is a member that fixes the air cylinder by abutting the pressing portion diagonally in front of the upper part of the air cylinder placed in the storage area of ​​the main frame and sandwiching the air cylinder between the pressing portion and the cylinder holding member. Furthermore, the pressing member is a member that releases the pressing portion from the air cylinder, thereby releasing the fixed air cylinder. Specifically, it is preferable that the pressing member consists of two vertical pieces extending forward from the left and right sides of the main frame and a horizontal piece connecting the upper front sides of the vertical pieces, and that the lower surface of the horizontal piece is provided with a pressing portion that abuts against the upper front side of the air cylinder and supports the air cylinder. The reason for this is that by moving the two vertical pieces located on the left and right sides of the main frame in an up and down motion, the horizontal piece can be rotated relative to the main frame, making it easier to operate the pressing member even with one hand.

[0045] As shown in FIG. 2, it is preferable that bearings or the like are disposed in through holes 15a formed in the left and right vertical pieces of the pressing member 14 and in through holes 13a formed in the main frame 12, and that the rotation shaft is passed through the bearings or the like. The reason for this is that the presence of such a rotation shaft allows the pressing member to rotate smoothly.

[0046] As shown in FIG. 2, it is preferable that the pressing member 14 has a stopper 20 at the end of at least one of the left and right vertical pieces to restrict the rotation angle of the pressing member 14. The reason for this is that by providing such a stopper, when the pressing member is lowered, it is possible to more efficiently prevent the pressing member from rotating further downward than the horizontal state as the fixed position. Furthermore, when returning the air cylinder to its original position, it is no longer necessary to hold up the pressing member with one hand, and the air cylinder can be placed more easily and quickly. Therefore, as shown in Figures 6(a) to (b), it is preferable to provide a stopper 20 having a U-shaped recess that opens upward on the side opposite to the side on which the horizontal piece 14a is attached, relative to the through hole 15a that serves as the central axis of rotation provided in the vertical piece 14b. In addition, it is preferable that a protrusion 20a having a shape corresponding to the recess is provided on the side surface of the mounting piece 12a on the side where the stopper 20 is provided. That is, as shown in FIG. 6(a), when the pressing member 14 is in the fixed position, the stopper 20 is in contact with the protrusion 20a, and it can be seen that the vertical piece 14b is in a horizontal state. On the other hand, as shown in FIG. 6(b), when the pressing member 14 is in the retracted position, it can be seen that the stopper 20 is separated from the protruding portion 20a and the vertical piece 14b is in a non-horizontal state.

[0047] As shown in FIG. 2, it is preferable that the pressing member 14 has a mounting hole 15b formed therein and a mounting hole 13b formed in the main frame 12 connected via a damper 32. The reason for this is that when the pressure member 14 is rotated, an elastic force and a damping force can be applied between the pressure member 14 and the main frame 12, and the pressure member 14 can be fixed in either a retracted position in which it is in a raised state, or a fixed position in which it is in a lowered state. Specifically, the damper consists of an arm and a cylindrical portion, and it is preferable that the lower end of the arm is attached to a mounting piece on the lower side of the main frame by a bracket, and the upper end of the cylindrical portion is attached to a vertical piece by a bracket.

[0048] 4. Bottom plate The lower end plate is a member placed on the bottom of the storage area surrounded by the main frame, which is the area where the air cylinder is placed. Specifically, as shown in FIG. 2, the lower end plate 30 preferably has a long hole 31a extending along the vertical direction, and is screwed through the long hole 31a into a screw hole 13d provided in the main frame 12. The reason for this is that by being screwed in through the long hole in this way, the height of the lower end plate can be adjusted more quickly to suit the size and shape of the air cylinder or the conditions of the location where the air respirator storage device is placed.

[0049] It is also preferable that the lower end plate be provided with a drain hole to prevent dust and water droplets adhering to the air cylinder from falling and accumulating. Furthermore, it is preferable that the bottom plate is bent in a dish shape around the periphery so that dust and water droplets do not flow out from areas other than the drainage holes.

[0050] 5. Air respirators An air respirator includes at least an air cylinder, and is a component for supplying air from the air cylinder, which is a high-pressure air container, to a user, for example, during firefighting activities by firefighters. Specifically, it is preferable that the air respirator includes, in addition to the air cylinder, an air supply mask that covers the entire face, an air supply hose that serves as a flow path for sending air to the air supply mask, a shoulder belt for carrying the air cylinder on the back, a stop valve, a regulator, etc.

[0051] Furthermore, from the viewpoint of speeding up the removal of the air cylinder, it is preferable to place the air cylinder 40 of the air respirator on the main frame 12 so that it stands upright along the vertical direction, as shown in Figure 7(a). In this case, it is preferable that the sliding lengths of the first cylinder holding member and the second cylinder holding member are equal. On the other hand, from the viewpoint of stability when the air cylinder is leaned against the main frame 12, it is preferable to place the air cylinder 40 of the air respirator on an incline so that it leans backward rather than vertically, as shown in Figure 7(b). In this case, it is preferable that the sliding length of the second cylinder holding member is longer than the sliding length of the first cylinder holding member.

[0052] [Second embodiment] The second embodiment is a method of using the storage device for respirators of the first embodiment, and includes the following steps. (1) A process for placing an air cylinder on a main frame in an air respirator. (2) A step of moving the cylinder holding member to abut against the side of the air cylinder. (3) A process of abutting the pressing member against the top of the air cylinder and fixing the air cylinder with the cylinder holding member and the pressing member. (4) A step of removing the holding member from the air cylinder to release the air cylinder from its fixed position. (5) The process of removing the air cylinder from the main frame.

[0053] 1.Pre-process The method of using the storage device for respirators of the present invention preferably includes a pre-step of preparing the respirators, as shown by reference character S1 in FIG. Specifically, it is preferable to fix the main frame of the storage device for respirators in the space behind the seats of a fire engine, and to prepare the respirators around the storage device for respirators. In addition, it is preferable to maintain the presser member of the respirator storage device in a horizontal position. The reason for this is that the preparation step allows the air respirator to be put on more quickly.

[0054] 2.Process (1) Next, step (1) is a step of placing an air cylinder, as shown by reference symbol S2 in FIG. That is, this is a process of transporting the prepared air cylinder to a storage area formed by being surrounded by a main frame, and placing it against a cylinder holding member. Here, it is preferable that the pressing member be rotated rearward to the retracted position before transporting the air cylinder. The reason for this is that by leaving the pressing member in the retracted position, the air cylinder can be quickly leaned against the cylinder holding member without interference from the pressing member. On the other hand, even if the pressing member remains in a fixed position, it is also preferable to insert the vertical lower part of the air cylinder into the storage area and then press the upper part of the air cylinder backward against the pressing portion, thereby rotating the pressing member backward without operating it.

[0055] 3.Process (2) Next, step (2) is a step of adjusting the cylinder holding member, as shown by reference symbol S3 in FIG. That is, this is a process of moving the cylinder holding member back and forth against the leaning air cylinder until the U-shaped portion comes into contact with it.

[0056] 4.Process (3) Next, step (3) is a step of fixing the air cylinder with a pressing member, as shown by reference symbol S4 in FIG. That is, this is a process in which the pressing member is rotated downward relative to the main frame to a fixed position, and the pressing portion provided on the pressing member is brought into contact with the upper, diagonally forward portion of the air cylinder. Specifically, in step (3), it is preferable to transport the air cylinder in a fixed state to the location where the air respirator is to be used by a fire engine or the like.

[0057] 5.Process (4) Next, step (4) is a step of releasing the air cylinder as shown by reference symbol S5 in FIG. That is, this is a process in which the pressing member is rotated in a springing manner relative to the main frame to a retracted position, and the pressing portion provided on the pressing member is released from the air cylinder.

[0058] 6.Process (5) Finally, step (5) is a step of removing the air cylinder, as shown by reference symbol S6 in FIG. That is, this is the process of pulling out the air cylinder connected to the shoulder strap from the storage area by putting the shoulder strap on, etc., and making the air cylinder ready for use. [Industrial Applicability]

[0059] The present invention can be used in various emergency vehicles and various equipment that are always equipped with breathing apparatus, such as fire engines, disaster vehicles, and transportation equipment. Therefore, even if no cushioning material is used, the shape and position of the pressing member can be quickly adjusted to match the size and shape of the air cylinder, and it is expected that the air cylinder will be stably fixed and supported. Furthermore, firefighters can easily put on or take off the air cylinder even while carrying it on their backs, which is expected to enable them to arrive at the scene more quickly. Furthermore, by preparing replacement parts with different arcs depending on the size of the air cylinder, it is expected that even small air cylinders that are easy for women to use and large air cylinders that can supply air for long periods of time can be stably supported.
