[0010] The following describes the opening / closing prevention devices according to each embodiment of the present invention with reference to the drawings. The description will detail the configuration of the embodiment, the method of implementation, and the modified examples in that order. The embodiments described below are examples of the present invention and do not limit the present invention to the embodiments described below. Furthermore, the term "abbreviated" in the application documents is a concept that includes shapes that have been chamfered or rounded, and shapes in which the elements constituting the shape have been deformed or modified in length to the extent that it does not impede the purpose or effect of the configuration. In this specification, the height direction of the housing 11 is defined as the up-and-down direction, the depth direction as the front-and-back direction, and the direction perpendicular to these as the width direction.

[0011] ≪First Embodiment≫ The present invention relates to an opening / closing prevention device X for a door 12 that opens outward, provided on equipment 1 having an outward-opening door 12, comprising an interference part 3 that interferes with the door 12, and a mounting part 2 attached to a position away from the door 12 of the equipment 1 to which the interference part 3 is attached, wherein the interference part 3 is slidably provided between an interference position in which it interferes with the door 12 and an open position in which the door 12 is opened, and an opening / closing prevention device X or a power distribution equipment equipped with an opening / closing prevention device X. In this way, by attaching the mounting part 2 to the equipment 1, retrofitting work is made easy, and by providing the interference part 3 to be slidable to the interference position, an opening / closing prevention device X that enhances security with simple operation can be provided.

[0012] As shown in Figures 1 to 3, the opening / closing prevention device X can be attached to equipment 1 having an outward-opening door 12, and comprises a mounting part 2 that is attached to the surface of equipment 1, an interference part 3 that can be attached to the mounting part 2 and whose position can be changed between an interference position in which it interferes with the door 12 and an open position in which the door 12 is opened, a covering part 4 that covers a part of the door 12, and a fixing means 5 that fixes the interference part 3 in the interference position to the mounting part 2 to prevent the door 12 from opening or closing. It is preferable to use carbon steel plate or SuperDyma (registered trademark) for the mounting part 2 and the interference part 3. Figure 3(a) is a side view of the opening / closing prevention device X when the interference part 3 is in the interference position, and Figure 3(b) is a schematic cross-sectional view of section AA.

[0013] Equipment 1 is a storage facility for various tools and equipment, comprising a housing 11 for storing items and an outward-opening door 12 provided on one side of the housing 11. In this embodiment, equipment 1 is a power distribution facility, and cable theft is suppressed by providing it with an opening / closing prevention device X. On the other hand, equipment 1 may also be a warehouse, a refueling facility or fuel tank room, a fire-fighting facility, or a communication facility, and is designed to prevent unauthorized persons from accessing the items inside.

[0014] The attachment part 2 is a connecting component that is attached to a part of the equipment 1 and enables the interference part 3 to be slidably attached. The attachment part 2 includes an attachment part main body 20 that is connected and fixed to the equipment 1, a guiding part 21 that guides the sliding of the interference part 3, a supporting part 22 that supports the interference part 3 located at the interference position, and an attachment and fixing part 23 that connects to the fixing means 5 when the interference part 3 is at the interference position.

[0015] The interference part 3 includes an interference part main body 30 that interferes with the door 12 when at the interference position, a sliding part 31 that slidably engages with the attachment part 2, a handle 32 that the user holds by hand during sliding, and an interference fixing part 33 that connects to the fixing means 5 when at the interference position. In the embodiment, the interference position is the position where it engages with the attachment part 2 and is supported by the supporting part 22, and the open position is the position where it is completely removed from the attachment part 2 and does not interfere with the door 12.

[0016] The covering part 4 is a part that covers the gripping part 121 described later when the interference part 3 is at the interference position, enhancing the security. In the embodiment, the interference part main body 30 acts as the covering part 4.

[0017] The fixing means 5 is a padlock in the embodiment and has a lock body 51 that simultaneously fixes the attachment and fixing part 23 and the interference fixing part 33. The fixing means 5 is not limited to a padlock, and a U-shaped lock, a chain lock, etc. may also be used.

[0018] The housing 11 is a substantially box-shaped member, surrounded by rigid members, and provided with a space inside that can store articles. The housing 11 has a housing front surface 111 where the door 12 is provided, a housing side surface 112 that is a surface standing adjacent to the housing front surface 111, a roof part, a bottom part, and a back part.

[0019] The door 12 is an outward-opening door arranged on the housing front surface 111 and is provided at a distance from the ground. It may be a double-opening or a single-opening door. The door 12 includes a door main body 120 that is a plate material provided with rigid members similar to the housing 11, and a gripping part 121 that the user grips when opening and closing.

[0020] The grip portion 121 is a recessed part of the door body 120 that faces inward, allowing a hand to be placed there. The grip portion 121 may also be provided with a keyhole (not shown), and covering this with the cover portion 4 can further enhance security.

[0021] The mounting body 20 is a plate material symmetrically provided on both sides of the housing side 112 in a position that does not interfere with the door 12. In this embodiment, the mounting body 20 is a plate material having a width in approximately the same direction as the front-rear direction of the housing side 112 and a length approximately the same as the height of the door 12, and is positioned along the upper end of the housing side 112. By providing the mounting body 20 in a manner corresponding to the housing side 112 in this way, the mounting position relative to the housing 11 can be clearly defined. Furthermore, the mounting body 20 is positioned away from the ground so that its lower end is below the door body 120, and the interference part 3 is provided to interfere with the lower part of the door 12. This simplifies the installation process and covers the gap at the lower end of the door 12, thereby enhancing security. The mounting body 20 is fixed by irreversible means such as rivets, welding, or adhesive, thereby enhancing security. In this case, the wide mounting body 20 increases the contact area with the housing 11, thereby improving the fixing performance.

[0022] The guide unit 21 is provided on the mounting unit body 20 and has a guide unit body 210 that functions as a rail that engages with a part of the interference unit 3, slides vertically, and holds it in the front-rear direction, and a guide assist unit 211 for guiding the interference unit 3 to the guide unit body 210. This allows the user to operate the interference unit 3 with intuitive and stable movements.

[0023] The guide unit body 210 is provided so as to bend at the end of the mounting unit body 20 on the door 12 side. The bending angle is perpendicular to the guide unit body 210 and extends parallel to the door body 120 when it is closed. As a result, no interference occurs even when the door 12 is opened 180°, improving ease of handling. In this embodiment, the mounting unit body 20 is provided by bending it, but a configuration in which a long angle or the like is attached may also be used. In this embodiment, the guide unit body 210 extends upward from the lower end of the mounting unit body 20, causing the interference unit 3 to slide vertically. This lowers the position where the interference unit 3 slides, simplifying the user's sliding operation. Since the guide unit body 210 extends vertically at least to the height of the lower end of the gripping portion 121, it firmly holds the interference portion 3 which is covering the gripping portion 121. Furthermore, the distance from the lower end of the mounting portion 2 to the upper end of the guide unit body 210 is shorter than the distance from the upper end of the guide unit body 210 to the roof portion of the housing 11, making installation work easy even if the vertical length of the interference portion 3 is long.

[0024] The guiding assist part 211 is a component that guides the interference part 3 and the guiding part body 210 to engage, and is provided on the mounting part body 20. The guiding assist part 211 protrudes from the surface of the mounting part body 20, away from the guiding part body 210. The vertical position of the guiding assist part 211 is above the guiding part body 210, making it easier to bring the interference part 3 into contact with the guiding part body 210 and guide it to the guiding part body 210. Furthermore, this effect can be further enhanced if the angle of the guiding assist part 211 is parallel to the guiding part body 210.

[0025] As shown in Figure 3, the horizontal position of the guiding support portion 211 is set at a distance from the guiding portion body 210 that is at least greater than the thickness of the material forming the sliding portion 31, thereby facilitating engagement of the sliding portion 31 with the guiding portion body 210. Preferably, the distance from the guiding portion body 210 to the guiding support portion 211 is smaller than the distance from the interference portion body 30 to the outer surface of the sliding portion 31, thereby further improving the guiding performance when in contact. In this embodiment, the guiding support portion 211 is an L-shaped bracket, with one side protruding from the mounting portion body 20.

[0026] The support portion 22 supports the interference portion 3 by contacting its lower end at the interference position. The support portion 22 is a member that protrudes from the mounting portion body 20 and is provided horizontally to horizontally support the plate-shaped interference portion 3. Furthermore, the support portion 22 is provided adjacent to the lower end of the guide portion body 210 to reliably support the interference portion 3 that has been guided and positioned at the interference position.

[0027] The mounting and fixing portion 23 is a through hole provided on the guide unit body 210. In this embodiment, it is provided on the upper part of the surface of the guide unit body 210, but it may also be provided on the lower part, or multiple portions may be provided.

[0028] The interference section body 30 is made of a rigid plate material, and its vertical length is approximately the same as that of the guide section body 210, so that the entire unit is held by the guide section body 210 without any excess or deficiency in the front-to-back direction. Its width is approximately the same as the width between the guide section bodies 210 provided on both sides of the housing side 112, and by covering the entire width of the door 12 and the front of the housing 111, it enhances the sense of intimidation and improves security. The vertical length can be changed arbitrarily, but it is preferable to make it shorter than the distance from the guide section body 210 to the roof portion of the housing 11 to facilitate installation work.

[0029] The sliding portion 31 is a part that is folded back at an acute angle from the widthwise end of the interference portion body 30, and its integration with the interference portion body 30 enhances security. The width of the sliding portion 31 is shorter than the protruding length of the guide portion body 210, and in the embodiment it is about 1 cm to 4 cm. The vertical length of the sliding portion 31 matches the vertical length of the interference portion body 30, resulting in high strength. The sliding portion 31 may be folded back in a U-shape, or it may be connected by welding to a separate component.

[0030] The handle 32 is a handle portion that protrudes from the opposite side (front side) of the sliding part 31. In this embodiment, it is provided by folding it back from the vertical end of the interference part body 30 to facilitate manufacturing. The handle 32 is folded back horizontally to make it easy to hold, and since the handle 32 is provided along the entire width, it is easy to slide the interference part 3 vertically so that it does not rotate. In addition, since the handle 32 is provided on both the top and bottom, the way of holding it can be easily changed when attaching and detaching it.

[0031] The interference fixing portion 33 is a hole that simultaneously penetrates the surface of the interference portion body 30 and the surface of the sliding portion 31, and is positioned so that the mounting fixing portion 23 is coaxial when the interference portion 3 is in the interference position. The interference fixing portion 33 may be provided on both sides, rather than just one side.

[0032] When the interference part 3 is in the interference position, the latch of the lock 51 simultaneously penetrates the mounting fixing part 23 and the interference fixing part 33, and in this state it is fixed to the cylinder. This prevents malicious removal of the interference part 3 and enhances the security performance.

[0033] The method of implementing the present invention will be described in detail below with reference to the drawings. The present invention is implemented by the user who installs and removes the interference portion 3 of the opening / closing prevention device X. Furthermore, the implementation method shown below is just one example, and the method of implementation is not limited thereto, and the order may be different. The method of use includes at least a release step of releasing the fixing means 5, and a sliding step of sliding the interfering part 3 from the interference position in which it interferes with the door 12 to the open position in which the door 12 is opened.

[0034] To install the device, the user first holds the handle 32 of the interference part 3 in the open position, brings the sliding part 31 into contact with the guide assist part 211, and stands the interference part body 30 upright so that its surface is perpendicular to the ground. This positions the sliding part 31 between the guide assist part 211 and the guide part body 210, allowing the interference part 3 to be easily installed by sliding it downwards. Next, in the sliding step, the user moves the interference part 3 to the interference position by sliding it downwards while it is engaged with the guide part body 210. At the interference position, the lower end of the interference part 3 contacts the support part 22, and in this state, the axes of the holes in the mounting fixing part 23 and the interference fixing part 33 align. Finally, in the fixing step, the user passes the latch through both the mounting fixing part 23 and the interference fixing part 33 simultaneously and fixes it with the lock 51. This prevents malicious opening and closing of the door 12.

[0035] To remove the door, the user first unlocks the lock 51 and removes it from the mounting fixing part 23 and the interference fixing part 33. Next, the user slides the interference part 3 upward in a sliding motion until it is in an open position where it does not interfere with the guide part 21. This allows the door 12 to be opened freely.

[0036] ≪Second Embodiment≫ The second embodiment will be described in detail below with reference to Figures 4 to 7. Components similar to those in the first embodiment will be described using the same reference numerals. Figure 5(a) is a perspective view showing the opening / closing prevention device X in a collapsed state (described later), and Figure 5(b) is a perspective view showing the opening / closing prevention device X in an upright state (described later). Figure 6(a) is an explanatory diagram showing how the interference part 3 is attached to the mounting part 2, and Figure 6(b) is a schematic cross-sectional view of the BB cross section when the interference part 3 is in the interference position.

[0037] The opening / closing prevention device X comprises equipment 1 having an outward-opening door 12, a mounting part 2 attached to the surface of equipment 1, an interference part 3 that can be attached to the mounting part 2 and whose position can be changed between an interference position in which it interferes with the door 12 and an opening position in which it opens the door 12, a covering part 4 that covers a part of the door 12, and a fixing means 5 that prevents the door 12 from opening when the interference part 3 is in the interference position.

[0038] Equipment 1 comprises a housing 11, an outward-opening door 12, and a base 13 provided between the housing 11 and the ground to horizontally support the housing 11. Mounting part 2 has a mounting part body 20, a guide part 21, and a support part 22. Interference part 3 has an interference part body 30, a sliding part 31, and a handle 32.

[0039] The cover portion 4 is provided to be switchable between an upright state leaning against the door 12 and a collapsed state lying on the ground or base 13. In the upright state, it is provided to cover the grip portion 121, the mounting portion 2, and the interference portion 3 when viewed from the front, preventing easy removal of the interference portion 3. The cover portion 4 includes a cover portion body 40 that covers the grip portion 121, a hinge 41 which is an axis that controls the upright and collapsed states, and a cover fixing portion 42 used when attaching the fixing means 5.

[0040] The fixing means 5 has a grip fixing lock 52 and a chain 53 that fix the grip portion 121 on the back side of the cover portion 4, thereby fixing the cover portion 4 in an upright position and preventing operation of the grip portion 121. In this embodiment, the grip fixing lock 52 is a padlock, and the latch portion is provided so as to be insertable into the chain 53. Although not shown, similar to the first embodiment, the mounting fixing portion 23 provided on the guide portion body 210 and the interference fixing portion 33 provided on the interference portion body 30 and the sliding portion 31 may also be fixed by the lock 51.

[0041] The base 13 is a foundation portion provided between the ground and the enclosure 11 by being poured with concrete or the like, and is a part of the equipment 1 that is large enough to include at least the entire bottom surface of the enclosure 11. The base 13 can be anything as long as it separates the ground from the enclosure 11, for example it may be a block material that supports the bottom surface of the enclosure 11.

[0042] The mounting body 20 is a plate material that is provided horizontally away from the housing 11 and the closed door 12, and is fixed to the base 13. In this embodiment, it has approximately the same width as the door 12 and is positioned to include the center of the door 12 in the width direction when viewed from the front. The mounting unit body 20 is fixed to the base 13 with irreversibly connected embedded bolts such as anchor bolts, thereby enhancing security by preventing it from being arbitrarily removed.

[0043] The mounting body 20 includes a guide reinforcement section 201 for reinforcing the guide section 21. The guide reinforcement section 201 is a plate material that connects the surface of the mounting body 20 and the upper end of the guide section 21 by welding, and maintains the upright position of the guide section 21 by forming a truss. The guide reinforcement section 201 may be made of ribs, square timbers, or the like, as long as it can reinforce the mounting body 20 and the guide section 21.

[0044] The guide portion 21 is a plate-shaped portion that protrudes perpendicularly from the surface of the mounting portion body 20, and in an embodiment, it is provided by bending it from the end edge of the mounting portion body 20 on the housing 11 side. The guide portion 21 has guide portion bodies 210 that slide and hold in the front-rear direction while engaging with the sliding portions 31 at both ends. The guide portion 21 is provided with a gap between the door 12 in the closed state and the door 12, at least equal to the thickness of the plate material constituting the interference portion 3. The vertical length of the guide portion 21 is set to be shorter than the distance from the base 13 to the lower end of the door body 120, allowing the interference portion 3 to be attached, and preventing interference with the door 12 when it is not attached. Furthermore, the width of the guide portion 21 is made longer than the width of the door 12 to improve security.

[0045] The guide body 210 extends outward in the width direction from at least the portion where the guide reinforcement portion 201 is provided, and is the portion that engages with the sliding portion 31. In this embodiment, the guide body 210 extends outward in the width direction from the mounting body 20, so that the entire interference portion 3 at the interference position comes into horizontal contact with the base 13, and the base 13 acts as a support portion 22.

[0046] The interference section body 30 is made of a rigid plate material, and its width is made longer than that of the guide section body 210, and its vertical length is made longer than the distance from the base 13 to the door 12, so that it can be attached to the guide section 21 and is positioned to interfere with the door 12 at the interference point. In addition, the vertical length of the interference section body 30 is made longer than the vertical length of the mounting section body 20, and the mounting strength is increased by contacting the entire vertical portion of the mounting section body 20 at the interference point.

[0047] The sliding portion 31 extends from both ends in the width direction of the interference portion body 30 and, in this embodiment, is folded back in a U-shape on the front side and integrally formed. Since the width direction length of the sliding portion 31 is shorter than the width direction length of the guide portion body 210, it can be installed without interfering with the guide reinforcement portion 201.

[0048] The handle 32 extends from the upper end of the interference part body 30 and, in this embodiment, is folded back in an L-shape to the same front side as the sliding part 31 and integrally formed. By providing it in this manner, the entire lower end of the interference part body 30 is supported by the base 13 and is positioned between the housing 11 and the guide part 21, thereby improving stability and strength at the interference location.

[0049] The cover body 40 is a plate material that has the same width as the mounting body 20 and is at least longer than the distance from the hinge 41 to the gripping part 121, and covers the gripping part 121 when upright. By making the height of the cover body 40 greater than the front-to-back length of the mounting part 2, the space formed between the cover body 4 and the housing 11 is narrowed, making it difficult to access the interference part 3 when upright.

[0050] The hinge 41 is a component that connects the mounting body 20 and the cover body 40, and is provided on the side of the mounting body 20 that faces the housing 11. In this embodiment, the hinge 41 is provided parallel to the end edge of the base 13, thereby preventing bending moments from occurring in the mounting body 20 and the cover body 40 and increasing their strength.

[0051] The cover fixing portion 42 is a hole provided in the cover body 40 for fixing the cover portion 4 using the grip fixing lock 52 and the chain 53. The cylinder of the grip fixing lock 52 cannot be inserted through the hole, but the hole is large enough to insert the chain 53 and the latch portion of the grip fixing lock 52, and is close to the grip portion 121 when the cover is upright.

[0052] The method of use of the invention according to this embodiment includes a covering step during installation. In the covering step, the user raises the main body 40 of the covering part, which is in a floppy state, to an upright state and leans it against the gripping part 121. With the covering part in an upright state, the user passes the chain 53 through the covering fixing part 42 from the outside to the inside, puts it on the gripping part 121, and passes it through the covering fixing part 42 from the inside to the outside. The user then inserts the latch portion of the grip fixing lock 52 into the inside of the covering part 4 via the covering fixing part 42 and fixes the chain 53 which is parallel on the inside, thereby fixing the covering part 4 in an upright state.

[0053] As an example of a modification of the second embodiment, as shown in Figure 8, the interference part 3 may be configured to engage with the guide part 21 when it is in the open position. Figure 8(a) is a schematic cross-sectional view of the position corresponding to the BB cross section when the interference part 3 is in the interference position, and Figure 8(b) is a schematic cross-sectional view when it is in the open position. In this case, the vertical height of the interference part 3 is set lower than the height from the base 13 to the lower end of the door body 120 so that the interference part 3 does not interfere with the door 12 when it approaches the base 13 (when it is in the open position). In addition, the sum of the distance from the base 13 to the mounting fixing part 23 and the distance from the interference fixing part 33 to the upper end of the interference part body 30 is made longer than the distance from the base 13 to the door 12. As a result, when the positional relationship between the mounting part 2 and the interference part 3 is fixed by the fixing means 5, the interference part 3 is positioned in the interference position so that the door 12 and the interference part 3 interfere with each other. This makes the interference part 3 easier to handle.

[0054] Furthermore, since the mounting part 2 is provided at the bottom of the door 12 and the interference part 3 is provided so as to be slidable in the vertical direction, even if the interference part 3 is heavy, removal can be easily done by pulling it out and installation can be easily done by dropping it. In addition, the presence of a support part 22 that supports the interference part 3 from below when it is in the interference position stabilizes the interference part 3 and makes it easier to install the fixing means 5.

[0055] Furthermore, since the interference section 3 is a panel that is wider than the width of the door 12, it enhances the sense of intimidation and makes physical destruction difficult, thereby improving security.

[0056] Furthermore, the mounting portion 2 has a guide portion 21 that protrudes from a part of the equipment 1, and the interference portion 3 has a sliding portion 31 formed by folding back its end.
