Description

  The present invention relates to a cylinder overturn prevention device. In particular, the present invention relates to a cylinder overturn prevention device for preventing the cylinder from overturning when the cylinder is used in a factory or a work site such as a construction site. There is no limitation on the gas filled in the cylinder, and various types such as acetylene gas, argon gas, and propane gas can be used.

A cylinder is often used in a factory or a construction site. The gas pressure inside the cylinder is extremely high, and care must be taken when handling it. In addition, some types of gas are flammable. Therefore, in order to ensure the safety of on-site work when performing welding and cutting work, it is necessary to keep the cylinder from falling over according to laws and regulations, and the temperature of the gas container. When there is a risk of ignition or explosion due to contact with dissimilar materials, it is required to keep measures taken to prevent contact.
In the prior art, various devices have been devised as a cylinder overturn prevention device for safely holding the cylinder.

  For example, as shown in FIG. 13, the cylinder overturn prevention device described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-83545) is directly or via a fixing device on a steel pillar of a work place such as a factory or a wall surface of the work place. A belt including a wide cloth, a length adjusting buckle material, and a pair of latches is prepared, and a cylinder is fastened to the hook member of the steel pillar or the wall surface with a belt.

  Further, for example, in the cylinder overturn prevention device described in Patent Document 2 (Japanese Patent Laid-Open No. 2000-35198), a pole is placed vertically on a solid pedestal, a bar is passed to the side of the pole, and a semicircle is placed on the bar. The arc-shaped support piece is attached and a chain for holding the cylinder is attached to the bar. As shown in FIG. 14, in a state where the cylinder is erected in the pedestal, the cylinder is brought into contact with and supported by a semicircular arc-shaped support piece, and the periphery of the cylinder is wound with a chain so as not to fall down. .

  In addition, for example, there are some that cover the cylinder with a cover. The cylinder overturning prevention device described in Patent Document 3 (Japanese Patent Laid-Open No. 8-193700) discloses a cylinder storage box that is partitioned into a first storage space and a second storage space by a partition wall. As shown in FIG. 15, an opening is provided in the front, and an opening / closing door is attached to the opening of the cylinder storage box.

  Some cover only the front rather than the entire periphery. Patent Document 4 (Japanese Patent Laid-Open No. 2000-266296) discloses a cover having a large opening at the rear and a space for accommodating a cylinder, as shown in FIG. Cover the front of the cylinder with a cover. In addition, in order to make it more stable and self-supporting, the chain is wound around the cylinder part of the cylinder and held.

  As described above, there are known cylinder overturn prevention devices that stably hold the cylinder. However, these conventional techniques have the following problems and there is room for improvement.

The cylinder overturn prevention device disclosed in Patent Document 1 has the following problems.
The first problem is that the installation becomes impossible depending on the environment of the work site. Since the cylinder overturn prevention device of Patent Document 1 is for fastening the cylinder with a belt, the installation area can be very small. However, in order to securely fasten the cylinder with the belt, it is necessary to wind the belt around an iron pole or to firmly connect both ends of the belt to the hooks provided on the wall of the work place. Such an appropriate iron pillar or an appropriate wall surface does not always exist in the environment of the site. Further, even if there is a wall surface, it is necessary to embed a member to be a hook on the wall surface, and such a modification is not easy.

The cylinder overturn prevention device disclosed in Patent Document 2 has the following problems.
The first problem is a problem that the installation area becomes large. The cylinder fall prevention device of Patent Document 2 has a large pedestal part, so the installation area of the cylinder fall prevention device becomes large, requiring a larger space than the original installation area of the cylinder, and the work efficiency at the site is reduced. There was a problem.
The second problem is that a semicircular arc-shaped support piece that matches the diameter of the cylinder must be prepared. In the cylinder overturn prevention device of Patent Document 2, a structure in which a semicircular arc-shaped support piece is brought into contact with and supported by the curved surface of the side wall surface of the cylinder in order to stably support the cylinder. It is necessary to abut using a semicircular arc-shaped support piece having an inner curved surface appropriately along the curved surface. However, the cylinder can have several variations in curvature of the curved surface depending on the type and capacity. Select a type that has a semicircular arc-shaped support piece that matches the curved surface of the cylinder used on site, or replace the semicircular arc-shaped support piece that matches the curved surface of the cylinder with a bar and install it. This is necessary and may reduce workability.

Next, the cylinder overturn prevention device disclosed in Patent Document 3 has the following problems.
The first problem is a problem that the installation area becomes large. In the cylinder overturn prevention device of Patent Document 3, since the entire cylinder is covered with a sturdy cover, the size of the cover is one or two times larger than the size of the cylinder. A space larger than the installation area is required, and there is a problem that work efficiency at the site is lowered.
The second problem is that a cover having an internal space that matches the diameter of the cylinder must be prepared. In the cylinder overturn prevention device of Patent Document 3, it is necessary to prepare a cover having a size suitable for the size of the cylinder in order to make the cylinder stable and self-supporting. There may be several types of variations in diameter size and height. The cover must be selected according to the size and height of the cylinder used at the site. However, the types of cylinders installed on the site are not always the same, and the cover must be replaced according to the size and height of the cylinders brought into the workplace, which may lead to a decrease in workability.

Next, the cylinder overturn prevention device disclosed in Patent Document 4 has the following problems.
The cylinder fall prevention device disclosed in Patent Document 4 also uses the cover that covers the cylinder as in the case of the cylinder fall prevention device of Patent Document 3, so that the above-described problem that the installation area increases and the diameter of the cylinder match. There is a problem that a cover having an internal space to be prepared must be prepared.

  Therefore, the present invention solves the above problems, and even if the cylinder type, diameter size, height, etc. are various, it can be attached to the cylinder without choosing the difference, and the attachment An object of the present invention is to provide a cylinder overturn prevention device that is simple in work, high in work efficiency, and capable of stably supporting the cylinder.

In order to solve the above-mentioned problem, the cylinder overturn prevention device of the present invention stands up around the grounding surface of a cylinder and has an abutment body having an abutment portion that abuts against a part of the lower wall surface of the cylinder, One or a plurality of connecting bodies for connecting the contact bodies are provided, and at least three or more of the contact bodies are arranged around the cylinder, and the contact portion of each of the contact bodies is disposed in the cylinder. This is a cylinder overturn prevention device that is fastened by the connecting body while being in contact with the lower wall surface of the cylinder and supports the cylinder.
From the above configuration, by arranging a plurality of contact bodies around the cylinder, the contact body can be easily arranged so as to surround the cylinder, regardless of the size of the cylinder and the curvature of the outer wall surface. It can be freely adapted. Moreover, if the width | variety of the contact part of each contact body is a moderate width | variety, it will not be influenced by the curvature of the outer wall surface of a cylinder, but can be along with the outer wall surface of a cylinder. When the contact body is tightened from the outer peripheral direction to the inner direction by the connecting body, the contact body can be supported integrally with the cylinder while pressing the contact body against the outer wall surface of the cylinder.

  As the number of contact bodies arranged around the cylinder, it is preferable to arrange three or more in consideration of balance. This is because in the case of three abutting bodies, the cylinders can be evenly supported from the outer periphery of the cylinder when arranged around the cylinder at intervals of 120 degrees. When four abutting bodies are arranged, it may be arranged around the cylinder at intervals of 90 degrees, and when six abutting bodies are arranged, it may be arranged around the cylinder at intervals of 60 degrees.

  Here, when the abutting body is manufactured by a casing made by bending a metal plate, an edge of the box that faces the cylinder is the abutting portion. Further, when the contact body is a plate body made of plastic, the edge of the plate body facing the cylinder is the contact portion.

Other devices can be incorporated as the shape of the contact body.
For example, it is a structure provided with a support body on the bottom surface of the contact body so that the contact body is not easily toppled. The shape of the support is not particularly limited, and there are various types such as a plate extending in the horizontal direction on the bottom surface.
In addition, the shape of the contact portion in the contact body can be devised. For example, when the cylinder edge is curved in an arch shape instead of a rectangle in order to fill with high-pressure gas, it is preferable that the contact portion has a curved surface along the curve. In supporting the cylinder, it is preferable that the lower wall surface is supported as firmly as possible to support the cylinder. However, the cylinder conforms to the shape of the outer wall surface below the cylinder.

Next, a device for facilitating the installation of the cylinder overturn prevention device of the present invention will be described.
The first device is a device in which a magnetic body is provided in the contact portion, and the contact body is simply attached temporarily around the cylinder. If the material of the cylinder wall surface is iron or stainless steel, the magnetic material can be adsorbed. Therefore, if the abutting portion is provided with a magnetic material, the cylinder can be easily attached around the cylinder. When the contact body is attached, the magnetic body is magnetically attached to the wall surface of the cylinder, whereby the contact body can be temporarily attached to the lower wall surface of the cylinder to facilitate positioning.

The second device is a device for easily mounting the connected body.
As a structure for mounting the connection body, the contact bodies arranged around the cylinder must be firmly pressed against the cylinder while connecting the plurality of contact bodies to each other. Therefore, the contact body is provided with a structure having a through-hole through which the connection body passes, and the connection body is passed through each contact body and fastened.

Further, as another structure for mounting the connection body, a structure provided with a notch groove for locking the connection body on the outer peripheral surface side of the contact body may be employed. If the notch groove is provided, the coupling body can be passed through the notch groove of each abutting body and fastened around the cylinder.
As another structure for mounting the connection body, a structure in which the connection body is an elastic body is also possible. By inserting the elastic body between the contact bodies adjacent to each other, the contact bodies can be evenly arranged around the cylinder while tightening the contact bodies by the elastic force of the elastic bodies. In addition, the contact body can be pressed against the cylinder.

  Next, as a device for preventing the cylinder from falling over, there is a device for ensuring a large falling angle in consideration of the relationship with the center of gravity of the cylinder. For example, an extended plate extending upward from the contact portion in the contact body is provided, and the length of the extended plate is set such that the position of the upper end is higher than the height of the center of gravity of the cylinder. There is. By providing the extended body having such a length, if the extended plate is brought into contact with the wall surface of the cylinder, the falling angle at which the cylinder is inclined and falls can be increased.

  According to the cylinder overturn prevention device of the present invention, it is possible to simply arrange a plurality of contact bodies so as to surround the cylinder by simply arranging each of the contact bodies around the cylinder. By wearing it, it can be freely adapted regardless of the size of the cylinder and the curvature of the outer wall. When the contact body is tightened from the outer peripheral direction to the inner direction by the connecting body, the contact body can be supported integrally with the cylinder while pressing the contact body against the outer wall surface of the cylinder.

  Hereinafter, embodiments of the cylinder overturn prevention device of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific application, shape, number, number and the like shown in the following embodiments.

The structural example of the cylinder fall prevention apparatus of this invention is shown.
FIG. 1 is a diagram simply illustrating a configuration example of a cylinder overturn prevention device 100 according to the first embodiment. FIG. 1A is a diagram showing a state in which the cylinder overturn prevention device 100 is mounted on the cylinder 200, FIG. 1B is a diagram showing a simple configuration example of the cylinder overturn prevention device 100, and FIG. FIG. 2 is a diagram simply showing another configuration example of the overturn prevention device 100, and FIG. 2 is a diagram showing the contact body 110 according to the first embodiment.
As shown in FIG. 1, the cylinder overturn prevention device 100 according to the first embodiment has a configuration including a contact body 110 and a connecting body 120.

The abutting body 110 is a member that stands up around the grounding surface of the cylinder 200 and supports the cylinder by contacting a part of the lower wall surface of the cylinder 200. Although the number of the contact bodies 110 arranged around the bomb 200 may be three or more, four are arranged in the example of FIG. 1A, and are arranged around the cylinder 200 at intervals of approximately 90 degrees. ing. What is necessary is just to be able to arrange at almost equal intervals even if not exactly 90 degrees.
A variety of materials can be applied to the contact body 110 as long as the material has a high structural strength, such as metal or plastic. For example, in the case of a metal, the contact body 110 can be manufactured by bending a metal plate. In the case of plastic, the contact body 110 can be molded by extrusion molding or the like. The configuration example shown in FIG. 1 is produced by bending a stainless steel into a so-called U-shaped casing.

In this configuration example, the contact body 110 has a structure including a contact portion 111 and a support body 112.
The abutting portion 111 is a portion that faces the cylinder 200 and abuts against the outer wall surface of the cylinder 200, and supports the cylinder 200 by abutting against a part of the lower wall surface of the cylinder 200. Yes.
As shown in FIG. 1B, the contact portion 111 is formed by bending a metal plate to form the contact body 110 into a U shape, and makes the edge portion on the front face contact the cylinder 200 with the contact portion 111. As shown in FIG. 1 (c), the contact body 110 is molded into a box shape or a column shape, and a recess along the curvature of the cylinder 200 is provided on the front surface. It is good also as what is called a "contact surface" which contacts the cylinder 200 as the contact part 111 as a whole.

Here, when the contact part 111 is an edge part on the tip side of the metal plate shown in FIG. 1B, it will be described that the merit that it is easy to cope with the cylinder 200 of various diameters is obtained.
FIG. 3 is a view simply showing from above the manner in which the abutting portion 111 of the abutting body 110 can abut against the outer wall surface of the cylinder 200 having various diameters. In FIG. 3, only the outer wall surface is indicated by a line without displaying the wall thickness on the outer wall surface of the cylinder 200.
As shown in FIG. 3, the abutting portion 111 is two parallel edges, and abuts against the outer wall surface of the cylinder 200 at its tip (lower side in the drawing). Here, three cylinders 200 having different sizes are drawn, but it can be seen that they can be in contact with two parallel edges regardless of the curvature, regardless of the curvature.
In this way, when the edge portion on the front end side where the metal plate is bent is used as the abutting portion 111, the diameter of the cylinder 200 is actually changed because it is in contact with the outer wall surface of the cylinder 200 by two parallel edges. Even if it is such a diameter, it can contact | abut with two parallel edges.

  On the other hand, as shown in FIG. 1 (c), the contact body 110 is molded into a box shape or a column shape, and a recess along the curvature of the cylinder 200 is provided on the front surface. In this case, there is an advantage that the area in contact with the outer wall surface of the cylinder 200 increases. When the contact area increases, the contact body 110 and the cylinder 200 are easily brought into close contact with each other, and the cylinder 200 can be supported more stably by the cylinder fall prevention device 100. However, since the curvature of the curve provided on the contact surface 111 is effective when matched with the curvature of the outer wall surface of the cylinder 200, it is necessary to prepare the contact body 110 according to the curvature of the outer wall surface of the cylinder 200.

Next, a device for bending near the lower surface of the contact surface 111 will be described.
As shown in FIG. 1A, the cylinder 200 has a substantially cylindrical shape, but the bottom surface of the cylinder 200 is often bulged in a convex curved shape. That is, generally, since the cylinder 200 holds gas at a high pressure, the edge portion is bulged in a convex curved shape so as to have a shape resistant to pressure. When the convex portion is bulged at the bottom of the cylinder 200 as described above, a curve along the convex curved bulge is attached to the vicinity of the lower surface of the contact surface 111 and protrudes toward the bottom surface of the cylinder 200. It shall be. With this device, the length and area with which the cylinder 200 and the abutting body 110 abut even in the vicinity of the bottom surface of the cylinder are increased, and the cylinder 200 and the abutting body 110 can be supported more stably.

Next, the support body 112 will be described.
The support body 112 is a member that supports the contact body 110 so that it does not easily fall over. In the example shown in FIG. 1, the support body 112 is a portion bent laterally from the bottom surface of the contact body 110. There can be various shapes of the support 112. In addition to the example of the plate provided in the lateral direction shown in FIG. 1, a configuration example in which blade members provided at the end of a so-called “skirt” are attached, and a support bar provided as a so-called “stick bar” A configuration example in which members are attached is also possible. In any case, the center of gravity of the contact body 110 is less likely to exceed the ground contact point of the support body 112, and the merit that it is difficult to fall is obtained.

Next, the connection body 120 will be described. The connecting body 120 is a member that connects the contact bodies 110 to each other. When the contact bodies 110 are fastened while being connected to each other by the connecting body 120, the contact body 110 can be tightened in the cylinder 200 side direction by applying an appropriate pressing force toward the inside.
The number of the connecting bodies 120 may be one as shown in FIG. 4 (a), or may be two or more as shown in FIG. 4 (b).
The material of the connecting body 120 may be any material that connects the contact bodies 110 to each other. For example, there are a belt-like cloth belt, a belt-like plastic belt, and an elastic body such as a spring. Here, a belt-like cloth belt will be described. An elastic body such as a spring will be described in a second embodiment.

When the connection body 120 is a belt-like belt, there are a plurality of methods for connecting the contact bodies 110 to each other. In addition to the structure of fastening through the through hole 113 shown in FIG. 1, there is a structure of fastening through the notch groove 114 and the like.
FIG. 5 is a view showing a method of attaching the connecting body 120 to the contact body 110 using the notch groove 114.
The configuration example of FIG. 1 includes a through hole 113 through which the connecting body 120 passes in the contact body 110, and the connection body 120 is inserted into the through hole 113 of each contact body 110 and fastened around the cylinder 200. Met. On the other hand, FIG. 5 includes a notch groove 114 that can lock the connecting body 120 on the outer peripheral surface side of the contact body 110. In this structure, the coupling body 120 is attached to each of the cut grooves 114. Thus, the connecting body 120 is passed through the plurality of abutting bodies 110 and fastened while being hooked in the cut groove 114, so that the abutting bodies 110 can be integrated together while being pressed against the outer wall surface of the cylinder 200. Therefore, stable attachment is possible even with this structure.
In the configuration example using the cutout groove 114, the connecting body 120 may be attached only by being fitted into the cutout groove portion 114 from the outside. Therefore, the connection body 120 is inserted into the through hole 113 shown in FIG. There is a merit that it can be installed more easily than the type that penetrates.

Next, the fixture 121 that loosens or tightens the coupling body 120 will be described.
In this configuration example, although not illustrated in FIG. 1 or the like, a fixing tool 121 for fastening the coupling body 120 is provided. Even in the general market, as a fixing member for a strap, a fastener that firmly fixes the strap so as not to move and move, such as a fastener such as a bag strap or a binding tool such as a cable, is well known. The connecting body 120 shown is also provided with such a fixture 121. Any member can be used as the fixing member as long as the connecting body 120 can be fixed so that the connecting bodies 120 do not move after the connecting body 120 is circulated around the cylinder.

Next, a flow of attaching the cylinder overturn prevention device 100 according to the first embodiment will be described. FIG. 6 is a diagram showing a flow of attachment work of the cylinder overturn prevention device 100.
First, the abutting bodies 110 are arranged appropriately and uniformly around the cylinder 200 to be fixed (procedure 1).
It is sufficient that the number of arrangement is three or more. However, four arrangements are made here, and the arrangement is made around the cylinder 200 at intervals of about 90 degrees. What is necessary is just to be able to arrange at almost equal intervals even if not exactly 90 degrees.
In this configuration example, the contact body 110 is manufactured by bending a metal plate, and the contact portion 111 is an edge of two pieces of metal plates. Therefore, it is not necessary to select the contact body 110 according to the outer diameter of the cylinder 200.

Next, the connecting body 120 is attached to the contact body 110 (procedure 2).
Although the attachment method of the connection body 120 to the contact body 110 depends on the structure of the contact body 110, here, it is assumed that the contact body 110 includes the through hole 113 as an example. The connecting body 120 is inserted into the through hole 113 of each contact body 110.

Next, the contact body 110 is appropriately tightened by the connecting body 120 and fixed by the fixture 121, and the cylinder 200 is pressed by the contact body 110 so as to be appropriately pressed (procedure 3).
Thus, by appropriately tightening the contact body 110 with the connecting body 120, the cylinder 200 of any diameter can be adapted, and the contact body 110 is held in a stable state by the fixture 121 with the connecting body 120. It can be fastened to the cylinder 200.
The cylinder 200 can be supported in a stable state by the contact portion 111 of the contact body 110 appropriately disposed around the cylinder 200.

  As described above, according to the cylinder overturn prevention device 100 of the present invention shown in the first embodiment, by arranging a plurality of contact bodies 110 around the cylinder 200, the cylinder 200 can be freely controlled regardless of the size of the cylinder 200 or the curvature of the outer wall surface. The contact body 110 can be fastened to the cylinder and supported by the connecting body.

The structural example of the cylinder fall prevention apparatus 100a of Example 2 is shown.
FIG. 7 is a diagram simply illustrating a configuration example of the cylinder toppling prevention device 100a according to the second embodiment. FIG. 7A is a diagram showing a state in which the cylinder overturn prevention device 100a is mounted on the cylinder 200, FIG. 7B is a diagram showing a simple configuration example of the cylinder overturn prevention device 100a, and FIG. It is a figure showing other examples of composition of fall prevention device 100 simply.
As shown in FIG. 7, the cylinder toppling prevention device 100a according to the second embodiment is configured to include a contact body 110a and a connecting body 120a.

  Similar to the first embodiment, the abutting body 110a is a member that stands up around the grounding surface of the cylinder 200 and supports the cylinder by contacting a part of the lower wall surface of the cylinder 200. The contact body 110 according to the first embodiment is a configuration example including the contact portion 111, the support body 112, and the through hole 113. However, the contact body 110a according to the second embodiment includes the contact section 111a and the support body 112a. In addition, it has a configuration including a connecting body joint 115a.

The connecting body joint 115a is a contact for attaching an end of a connecting body 120a, which is an elastic body, which will be described later, and is, for example, a part joined by metal welding.
The material of the contact body 110a is preferably stainless steel when metal welding is performed.

The connection body 120a is an elastic body disposed between the contact bodies 110a, and the connection body 120a is inserted between adjacent contact bodies 110a.
Examples of the elastic body may include a spring and rubber. In this configuration example, the connecting body 120a is formed of a metal spring.

Since the connection body 120a is inserted between the contact bodies 110a, when there are four contact bodies 110a, there are also four connection bodies 120a and are disposed between the contact bodies 110a.
Here, one of the four coupling bodies 110a has a detachable structure. In this example, as shown in FIG. 8, a hook type attachment / detachment point 116a is provided. By being detachable at the detachment point 116a, a part of the contact body 110a and the connecting body 120a that are connected in a ring shape can be opened, and the cylinder 200 can be wound around the cylinder 200. The abutting body 110a and the connecting body 120a can be connected in a ring shape while being wound 200.

Prior to mounting on the cylinder 200, the connected member of the contact body 110a and the connecting body 120a may be in a state in which the attachment / detachment point 116a is opened instead of being annular.
FIG. 9 is a diagram illustrating a state in which the members connected to the contact body 110a and the connection body 120a are assembled in a ring shape with the state opened at the attachment / detachment point 116a.
When the connecting body 120a is formed of an elastic body such as a spring and is assembled in an annular shape around the cylinder 200, as shown in FIG. 9B, the distance between the contact body 110a and the contact body 110a is naturally uniform. This is advantageous in that the positioning of the plurality of contact bodies 110a around the cylinder 200 is easy.

  Further, by configuring the connecting body 120a with an elastic body such as a spring, it can be appropriately expanded and contracted in accordance with the outer diameter of the cylinder 200, the interval between the contact bodies 110a is adjusted naturally, and the spring can be expanded and contracted. Since the length is freely adjusted within a certain range, the connecting body 120a can be appropriately expanded and contracted regardless of the outer diameter of the cylinder 200, and the contact body 110a can be disposed around the cylinder 200. Benefits that can be obtained.

Further, there is an advantage that the procedure for mounting the cylinder overturning prevention device 100a of the second embodiment to the cylinder 200 is simpler than that of the first embodiment.
As a procedure for mounting the cylinder overturn prevention device 100a of the second embodiment to the cylinder 200, first, the cylinder overturn prevention device 100a is wound around the cylinder 200 to be fixed (procedure 1).
At this time, the contact body 110a is arranged around the cylinder 200 appropriately and evenly only by winding the member connected to the contact body 110a and the connection body 120a.
If the number of the contact bodies 110a is four, each of the contact bodies 110a is arranged around the cylinder 200 at an interval of approximately 90 degrees.

Next, the attachment / detachment point 116a of the connection body 120a is attached, and the members connected to the contact body 110a and the connection body 120a are assembled in an annular shape (procedure 2).
The connecting body 120a is an elastic body, and when assembled in an annular shape, an appropriate tension is generated, and a force for pressing the contact body 110a against the outer wall surface of the cylinder 200 is generated.

  The cylinder overturning prevention device 100a according to the second embodiment may be attached only by the above two steps. However, in order to further improve the stability, the belt-like connecting body 120 shown in the first embodiment is separately attached to the abutting body 110a. It may be attached. That is, the connecting body 120a formed of the elastic body is positioned so as to be appropriately disposed on the outer wall surface of the cylinder 200 of the contact body 110a, and the contact body 110a is tightened by the connection body 120 shown in the first embodiment. Attachment may be performed by wearing. When the band-shaped connecting body 120 is used in combination, the contact body 110a needs to be provided with the through hole 113 and the notch groove 114 shown in the first embodiment in addition to the connecting body joint 115.

  As described above, according to the cylinder toppling prevention device 100a of the present invention shown in the second embodiment, the plurality of contact bodies 110a can be appropriately arranged around the cylinder 200 by the connecting body 120a formed of an elastic body. The cylinder 200 can be freely adapted regardless of the size of the cylinder 200 and the curvature of the outer wall surface.

The structural example of the cylinder fall prevention apparatus 100b of Example 3 is shown.
The third embodiment is a device in which a magnetic body is provided in the contact portion, and the contact body is simply attached temporarily around the cylinder.
FIG. 10 is a diagram simply illustrating a configuration example of the cylinder toppling prevention device 100b according to the third embodiment.
FIG. 10A is a diagram simply illustrating an example of the configuration of the cylinder overturning prevention device 100b according to the third embodiment. FIG. 10B is a diagram illustrating a case where the contact body 110b is magnetically attached to the cylinder 200 via the magnetic body 117b. It is a figure which shows a mode that attachment is attached and positioning is changed easily.
As shown in FIG. 10 (a), the cylinder overturn prevention device 100b according to the third embodiment is similar to the first embodiment in that it includes a contact body 110b and a connecting body 120b. The difference is that the magnetic body 117 is disposed in the contact body 110b.

  Since the contact body 110b includes the magnetic body 117b on the contact surface 111b, when the wall surface of the cylinder 200 is made of iron, the contact body 110b can be easily magnetically attached. . Therefore, when the cylinder overturn prevention device 100b is attached to the cylinder 200, the contact body 110b is simply magnetically attached to the wall surface of the cylinder 200 via the magnetic body 117b, and temporarily attached to the lower wall surface of the cylinder 200. The merit which can make positioning easy is acquired.

If the magnetic body 117b is magnetically attached, and if it is desired to adjust the position of the temporarily attached contact body 110b, the contact body 110b is again attached to the cylinder 200 as shown in FIG. It can be peeled off the wall and magnetized again at another position.
Thus, in the cylinder overturn prevention device 100b according to the third embodiment, the contact body 110b is simply magnetically attached to the wall surface of the cylinder 200 via the magnetic body 117b and temporarily attached to the lower wall surface of the cylinder 200. Positioning can be easily changed and adjusted.

The fourth embodiment is a device for ensuring a large fall angle in consideration of the relationship with the center of gravity of the cylinder as a device for preventing the cylinder from falling.
FIG. 11 is a diagram simply illustrating a configuration example of the cylinder toppling prevention device 100c according to the fourth embodiment. FIG. 11A is a diagram illustrating a state in which the cylinder overturning prevention device 100c is mounted on the cylinder 200, and FIG. 11B is a diagram simply illustrating a configuration example of the cylinder overturning prevention device 100a.
Moreover, FIG. 12 is a figure for demonstrating the effect of the extension body 118c. In FIG. 12, in order to illustrate the positional relationship between the center of gravity G and the upper end A of the extended body 118c in an easy-to-understand manner, the contact body 110c and the connecting body 120c on the front side are not shown.

  As shown in FIG. 11, the cylinder overturn prevention device 100c according to the fourth embodiment is the same as the first embodiment in that it includes a contact body 110c and a connecting body 120c. An extending plate 118c extending upward from the contact portion 111c is provided.

The extending plate 118c makes it difficult for the cylinder 200 to fall, and increases the fall angle of the cylinder 200.
The tipping angle is the angle at which a person who falls by himself or herself is tilted when tilted further. When the cylinder 200 is applied to the cylinder 200, the bottom edge becomes the contact point when the cylinder 200 is tilted. In the state where the center of gravity of the cylinder 200 is located inside the contact point that is the bottom edge, Unless there is an external force, it moves inward, that is, in a direction in which the inclination is corrected. However, when the center of gravity of the cylinder 200 is positioned outside the contact point that is the edge of the bottom surface, the cylinder 200 is then turned outwards, that is, the inclination is increased and falls even if no external force is applied. Thus, even if no external force is applied, the angle at which tilting and starting to fall is called a fall angle.

As shown in FIG. 12, the extension body 118 c has a length such that the position A at the upper end is higher than the height of the center of gravity of the cylinder 200. If the extension plate 118c is brought into contact with the wall surface of the cylinder 200 by providing the extension body 118c having such a length, the falling angle at which the cylinder 200 tilts and falls can be increased.
When the contact body 110 is supported and falls, a large external force is applied, and a gap is generated between the contact body 110 and the cylinder 200, and the center of gravity of the cylinder 200 is the edge of the bottom surface. This is a case where the distance exceeds the contact point and further exceeds the upper end of the contact body 110.
However, in the configuration of the fourth embodiment, the contact body 110c includes the extension body 118c, and the position A of the upper end of the extension body 118c is higher than the position of the center of gravity G of the cylinder 200. The center of gravity G of 200 does not exceed the upper end A of the contact body 110. At least, by providing the extended body 118c, it is possible to help the cylinder 200 not easily fall down.
