The slide body 2 can slide back and forth between the storage position P21 shown in FIG. 2 and the drawer position P22 shown in FIG. 3, and the left and right arm portions 3 are in the standing posture P31 shown in FIG. 4 and lying down shown in FIG. It is rotatable with and from the posture P32.

The plurality of slide rails 6 will be described in more detail.

As shown in FIGS. 2 and 3, the plurality of slide rails 6 are three slide rails 6 located at a distance from each other in the vertical direction. The three slide rails 6 are an upper slide rail 6a connected to the upper part of the slide body 2, a lower slide rail 6b connected to the lower part of the slide body 2, and an upper slide rail 6a and a lower slide rail 6b in the vertical direction. It is an intermediate slide rail 6c connected to the slide body 2 so as to be located between them.

The upper slide rail 6a, the lower slide rail 6b, and the intermediate slide rail 6c have the same basic structure, and each has a bearing member 62 and two rails 64, 66 slidably connected to the front and rear via the bearing member 62. .. The two rails 64 and 66 are a fixed rail 64 and a movable rail 66. The fixed rail 64 is attached to the side of the filling table 12, and the movable rail 66 is attached to the side of the slide body 2.

The upper slide rail 6a and the lower slide rail 6b are installed horizontally, and the intermediate slide rail 6c is installed vertically. That is, in the upper slide rail 6a and the lower slide rail 6b, the long plate-shaped fixed rail 64 and the movable rail 66 are installed so as to overlap each other in the vertical direction. On the other hand, in the intermediate slide rail 6c, the fixed rail 64 and the movable rail 66 are installed so as to overlap each other in the left-right direction.

In this way, among the plurality of slide rails 6 (6a, 6b, 6c), the direction (left-right direction) in which the fixed rail 64 and the movable rail 66 overlap in one slide rail 6 (6c) is set to the other slide rail 6 (left-right direction). In 6a and 6b), the fixed rail 64 and the movable rail 66 are offset by 90 degrees from the overlapping direction (vertical direction), so that the wobbling directions of the plurality of slide rails 6 cancel each other out. As a result, wobbling of the slide body 2 (particularly, when the slide body 2 is pulled forward, it falls down) is suppressed. The 90 degrees referred to in the text is not limited to 90 degrees in a strict sense, and includes the case of approximately 90 degrees.

It is preferable that at least one of the plurality of slide rails 6 is provided with a stopper. This stopper is a member that gives a drag force against the forward sliding movement of the movable rail 66 when the fixed rail 64 and the movable rail 66 are in the stored state as shown in FIG. 2, for example, the movable rail 66. It is composed of a resin member that gives frictional force.

Next, the slide body 2 will be described in more detail.

As shown in FIG. 2, when the plurality of slide rails 6 are in the stored state, the slide body 2 is at the rearmost storage position P21 within the range in which it can slide. As shown in FIG. 3, when the plurality of slide rails 6 are in the extended state, the slide body 2 is at the frontmost drawer position P22 in the range in which it can slide.

The front portion of the slide body 2 includes a vertically linear vertical piece 21 vertically and a handle portion 22 formed on the upper portion of the vertical piece 21. The handle portion 22 has an insertion port 221 through which an operator can insert his / her own fingers, and a grip 225 formed in front of the insertion port 221. The operator can grasp the grip portion 225 with his / her own fingers passed through the insertion port 221 and slide the slide body 2 back and forth.

The left and right arm portions 3 are rotatably connected to the vertical piece 21. In the double-sided type fall prevention device 10, the left and right arm portions 3 have a line-symmetrical configuration, and the basic configurations of the left and right arm portions 3 are common.

In the following, the configuration of the arm portion 3 will be collectively described without distinguishing between the left and right sides.

The arm portion 3 includes a rod-shaped upper arm 31, a rod-shaped lower arm 33 located below the rod-shaped upper arm 31, and a link mechanism 35 for interlocking the upper arm 31 and the lower arm 33. The upper arm 31 and the lower arm 33 are round bar-shaped metal members having the same dimensions and shapes.

The vertical piece 21 is provided with a plurality of joints 5 for rotatably supporting the arm portion 3. More specifically, a joint 5 for rotatably supporting the upper arm 31 is provided above the vertical piece 21, and another joint 5 for rotatably supporting the lower arm 33 is provided below the vertical piece 21. A joint 5 is provided.

The link mechanism 35 includes a connecting rod 350 rotatably connected to the upper arm 31 and the lower arm 33. The upper end of the vertically long connecting rod 350 is connected to the middle part of the upper arm 31 in the length direction, and the lower end of the connecting rod 350 is connected to the middle part of the lower arm 33 in the length direction. ing. Through the connecting rod 350, the upper arm 31 and the lower arm 33 are interlocked so as to take the same posture with each other.

As shown in FIG. 4 and the like, when the upper arm 31 takes an upright posture, the lower arm 33 also takes an upright posture in conjunction with it. When both the upper arm 31 and the lower arm 33 are in the standing posture, the standing posture P31 of the arm portion 3 is obtained. The standing posture P31 of the arm portion 3 is a posture in which the arm portion 3 stands up so as to extend upward as a whole. That is, in the standing posture P31 of the arm portion 3, the upper arm 31 stands up so as to extend upward, and the lower arm 33 stands up so as to extend upward, and the upper arm 31 and the lower arm 33 are connected to each other in the front view. The posture is such that 350s overlap in a straight line.

Similarly, when the upper arm 31 takes a lying position, the lower arm 33 also takes a lying position in conjunction with it (see FIG. 5). When both the upper arm 31 and the lower arm 33 are in the recumbent posture, the arm portion 3 is in the recumbent posture P32. The recumbent posture P32 of the arm portion 3 is a posture in which the arm portion 3 is tilted so as to extend laterally as a whole. That is, the recumbent posture P32 of the arm portion 3 is a posture in which the upper arm 31 is tilted so as to extend laterally and the lower arm 33 is tilted so as to extend laterally.

The joint 5 that supports the arm portion 3 is configured by using a torque hinge 50 so as to generate a torque that opposes the rotation of the arm portion 3 here.

Hereinafter, the torque hinge 50 will be described.

As shown in FIGS. 7 and 8, the torque hinge 50 is sandwiched between the rotating shaft 51, a pair of blade plates 53 rotatably connected via the rotating shaft 51, and a pair of blade plates 53. An intermediate member 55 made of resin is provided. When the pair of blade plates 53 rotate relative to each other, the torque hinge 50 generates a torque against the rotation by causing frictional force by sliding contact with at least one of the pair of blade plates 53 and the intermediate member 55. ..

In the upper torque hinge 50 connected to the upper arm 31, one of the pair of blade plates 53 is fixed to the upper end portion of the vertical piece 21, and the other of the pair of blade plates 53 is fixed to the base portion of the upper arm 31. Will be done. As a result, the upper arm 31 can be tilted and tilted within a range of 90 degrees so as to change the posture between the vertical standing posture and the horizontal lying posture. The vertical wording used in the text is not limited to vertical in the strict sense, and includes the case of being substantially vertical. Similarly, the horizontal wording used in the text is not limited to horizontal in the strict sense, and includes the case of being substantially horizontal.

In the lower torque hinge 50 connected to the lower arm 33, one of the pair of blade plates 53 is fixed to the lower end of the vertical piece 21, and the other of the pair of blade plates 53 is attached to the base of the lower arm 33. It is fixed (see FIGS. 2 and 3). As a result, the lower arm 33 can be tilted and tilted within a range of 90 degrees so as to change the posture between the standing posture and the lying posture.

In addition, the slide body 2 is provided with a contact member 7 and a stopper 8. The contact member 7 is a member that stably stops the rotation of the arm portion 3 in the recumbent posture P32. The stopper 8 is a member that prevents the arm portion 3 in the lying posture P32 from tilting forward.

The contact member 7 will be further described.

FIG. 8 shows a contact member 7 for stopping the upper arm 31 included in the arm portion 3 in a horizontal lying posture. The contact member 7 is a flat metal member attached to the upper part of the slide body 2 so as to abut the flat base end surface of the upper arm 31 when the upper arm 31 is in the recumbent posture. The contact member 7 is screw-fixed to the slide body 2 via a blade plate 53 fixed to the upper portion of the slide body 2 among the torque hinges 50 that support the upper arm 31. That is, the contact member 7 is fixed to the slide body 2 together with the blade plate 53 in a state where the blade plate 53 is sandwiched between the contact member 7 and the slide body 2.

As shown in FIGS. 2 and 3, a similar contact member 7 is fixed to the lower portion of the slide body 2 in order to stop the lower arm 33 in a recumbent posture. The configuration of the lower contact member 7 is the same as the configuration of the upper contact member 7. The lower contact member 7 is fixed to the lower part of the slide body 2 via the blade plate 53 of the lower torque hinge 50 so as to come into contact with the base end surface of the lower arm 33 in the recumbent posture.

Next, the stopper 8 will be described.

As shown in FIGS. 5 and 6, the slide body 2 has an upper stopper 8 for suppressing the forward tilt of the upper arm 31 and a lower stopper 8 for suppressing the forward tilt of the lower arm 33. A stopper 8 is attached.

The upper stopper 8 is composed of a flat metal plate 81 fixed to the upper end of the front portion of the slide body 2. The metal plate 81 is fixed to the slide body 2 in a vertical posture so that its thickness direction is the front-rear direction.

The upper stopper 8 is located so as to cover the front of the base end portion of the upper arm 31 when the upper arm 31 is in the horizontal lying position. In front view, the base end portion of the upper arm 31 in the lying position is hidden by the upper stopper 8. Therefore, even if a large load acts on the upper arm 31 such as when the cylinder 9 hits the upper arm 31, the base end portion of the upper arm 31 hits the stopper 8 and stops, so that the upper arm 31 tilts forward. That is suppressed.

The lower stopper 8 has the same configuration as the upper stopper 8. That is, the lower stopper 8 is composed of a flat metal plate 81 fixed to the lower end of the front portion of the slide body 2. The metal plate 81 is fixed to the slide body 2 in a vertical posture so that its thickness direction is the front-rear direction.

The lower stopper 8 is located so as to cover the front of the base end portion of the lower arm 33 when the lower arm 33 is in the horizontal lying position. In front view, the base end portion of the lower arm 33 in the lying position is hidden by the lower stopper 8. Therefore, even if a large load acts on the lower arm 33, the base end portion of the lower arm 33 hits the stopper 8 and stops, so that the lower arm 33 is prevented from tilting forward.

As described above, the fall prevention device 10 shown in FIGS. 2 to 8 is a double-sided type fall prevention device 10. Therefore, the left arm portion 3 is rotatably supported on the left side of the vertical piece 21 included in the slide body 2 via the two upper and lower joints 5, and on the right side of the vertical piece 21 via the upper and lower two joints 5. The right arm portion 3 is rotatably supported.

More specifically, the upper arm 31 on the left side is rotatably supported on the left side of the upper part of the vertical piece 21 via the joint 5, and the upper arm 31 on the right side is rotatably supported on the right side of the upper part of the vertical piece 21 via the joint 5. Is rotatably supported. Similarly, the lower arm 33 on the left side is rotatably supported on the left side of the lower part of the vertical piece 21 via the joint 5, and the lower arm 33 on the right side rotates on the right side of the lower part of the vertical piece 21 via the joint 5. It is supported freely.

The metal plate 81 constituting the upper stopper 8 has both a function of suppressing the inclination of the upper arm 31 on the left side and a function of suppressing the inclination of the upper arm 31 on the right side. That is, the left half of the upper metal plate 81 can suppress the inclination of the left upper arm 31, and the right half of the metal plate 81 can suppress the inclination of the right upper arm 31. ..

Similarly, the metal plate 81 constituting the lower stopper 8 has both a function of suppressing the inclination of the lower arm 33 on the left side and a function of suppressing the inclination of the lower arm 33 on the right side. The left half of the lower metal plate 81 can suppress the inclination of the left lower arm 33, and the right half of the metal plate 81 can suppress the inclination of the right lower arm 33.

Further, the double-sided type fall prevention device 10 further includes a hook type connecting mechanism 4 for connecting the left and right arm portions 3 to each other in the standing posture P31. As shown in FIGS. 4 and 5, the connecting mechanism 4 includes a hook 40 rotatably installed in a part of the left arm portion 3 (intermediate portion in the length direction of the left upper arm 31). The hook 40 is detachably hooked on a part of the right arm portion 3 (the intermediate portion in the length direction of the right upper arm 31).

The number of hooks 40 is not limited to one, and a plurality of hooks 40 can be provided. Further, the place where the hook 40 is provided is not limited to a part of the left arm part 3, but it is also possible to provide the hook 40 in a part of the right arm part 3, and both the left and right arm parts 3 are provided. It is also possible to provide it.

The double-sided type fall prevention device 10 has been described above based on FIGS. 2 to 8. As shown in FIG. 1, the gas filling facility 1 of one embodiment is provided with four double-sided type fall prevention devices 10 on one side and two single-sided type fall prevention devices 10, and vice versa. The same arrangement is made on the surface side. Therefore, in the gas filling facility 1 of one embodiment, it is possible to fill each cylinder 9 with gas while preventing the 20 cylinders 9 from tipping over on each of the one side and the opposite side.

Next, a procedure for filling the cylinder 9 with gas using the gas filling facility 1 of one embodiment will be described.

When the gas filling operation is not performed, the slide body 2 of the fall prevention device 10 is set at the storage position P21, and the arm portion 3 is set at the standing posture P31 (see FIG. 2). As a result, the fall prevention device 10 is compactly housed and is prevented from interfering with other work. Further, it is possible to prevent the fall prevention device 10 from being damaged by applying some external force.

After the cylinder 9 to be filled is leaned against the filling table 12, the operator pulls the slide body 2 of the fall prevention device 10 at the corresponding position forward and slides it to the drawer position P22 (see FIG. 3).

Next, the operator tilts the arm portion 3 in the standing posture P31 and rotates it until the lying posture P32 (see FIGS. 4 and 5). At this time, in the double-sided type fall prevention device 10, the hook 40 is first removed, and then the left and right arm portions 3 are rotated in a direction away from each other. Since the rotation speed of the arm portion 3 is reduced by the torque generated by the torque hinge 50, a situation in which the arm portion 3 suddenly falls can be suppressed.

When both the left and right arm portions are in the recumbent posture P32, the left arm portion 3 and the right arm portion 3 project in a direction away from each other in the horizontal direction. Specifically, the upper arm 31 included in the left arm portion 3 and the upper arm 31 included in the right arm 3 project in a straight line so as to be separated from each other in the horizontal direction. Similarly, the lower arm 33 included in the left arm portion 3 and the lower arm 33 included in the right arm 3 project in a straight line so as to be separated from each other in the horizontal direction.

In this state, the arm portion 3 is positioned so as to cross the front of the cylinder 9. Even if an earthquake or the like occurs, the arm portion 3 functions to prevent the cylinder 9 from tipping over.

When the gas filling operation is completed, the fall prevention device 10 is stored in the reverse procedure. That is, after the arm portion 3 in the lying posture P32 is lifted to the standing posture P31, the slide body 2 is pushed in and slid to the storage position P21.

By repeating the above operation many times, a large number of cylinders 9 can be sequentially filled with gas. Moreover, the work for preventing the fall at each time can be easily and collectively performed by using the fall prevention device 10. Therefore, the overall work efficiency is greatly improved.

(Modification example)
The above-mentioned fall prevention device 10 and the gas filling facility 1 provided with the above-mentioned fall prevention device 10 are only one embodiment, and the design can be appropriately changed within a range in which the same effects are exhibited.

For example, in the fall prevention device 10 of one embodiment, the arm portion 3 includes two arms (upper arm 31 and lower arm 33) that can be tilted freely, but the present invention is not limited to this, and the upper arm 31 and the lower arm are not limited thereto. It is also possible to provide one or three or more foldable arms similar to 33. When a single arm is provided, the connecting mechanism 4 is unnecessary. When three or more arms are provided, it is preferable to provide a connecting mechanism 4 for interlocking these arms.

Further, although the fall prevention device 10 of one embodiment includes the above-mentioned hook type mechanism as the connecting mechanism 4, other methods can also be used. For example, each of the left and right arm portions 3 is provided with a plunger having a structure in which a locking body such as a ball elastically protrudes, and when the left and right arm portions 3 are in the standing posture P31, the locking body protruding from each plunger is locked. It is also possible to provide the body so that it is elastically hooked on the slide body 2.

Further, in the fall prevention device 10 of one embodiment, the torque hinge 50 is used as the joint 5, but a joint having another structure can be adopted as long as it generates the same torque.

Further, although the gas filling facility 1 of one embodiment includes a double-sided type and a single-sided type as the fall prevention device 10, it is also possible to provide only one or a plurality of double-sided type fall prevention devices 10. However, it is also possible to provide one or more one-sided type fall prevention devices 10.

Further, in one embodiment, the fall prevention device 10 is provided in the gas filling facility 1, but the target for installing the fall prevention device 10 is not limited to the gas filling facility 1. A similar fall prevention device 10 can be preferably installed as long as the equipment accommodates the cylinder 9 leaning against it.
