Description

  The present invention relates to a technical field of a hinge device that couples two members in a swingable manner.

In general, a hinge is generally used when two members are swingably connected. For example, in a construction machine such as a hydraulic excavator, the door, hatch, engine hood, etc. of a cab is opened and closed on the vehicle body. It is used when mounting freely. By the way, when assembling or disassembling two members connected by a hinge, it may be necessary to disassemble the hinge itself, so that the hinge can be disassembled by pulling out the hinge pin. Hinges are conventionally known. However, when such a releasable hinge is to be used in the construction machine, it is possible to reliably prevent the hinge from being inadvertently disassembled when it is not intended, and for example, at the time of a disaster, etc. When it is urgently necessary to remove a door or hatch, it is required to quickly disassemble the hinge without using a tool.
Therefore, a technique has been proposed in which a holding member that engages with first and second annular grooves formed on the hinge pin is provided on the hinge body (see, for example, Patent Document 1). In this case, with the hinge connecting two members, the holding member engages with the second annular groove of the hinge pin, thereby preventing the axial movement of the hinge pin and holding the hinge pin in place. On the other hand, by gripping the grip portion formed at the end of the hinge pin and pulling the hinge pin in the axial direction, the engagement between the holding member and the second annular groove of the hinge pin is released so that the hinge can be disassembled. It is configured. Further, when the hinge is disassembled, the holding member is engaged with the first annular groove of the hinge pin, so that the hinge pin is prevented from falling off from the hinge body.

Japanese Patent Laid-Open No. 9-328947

  By the way, a force to move in the axial direction acts on the hinge pin as the hinge swings. For this reason, in the thing of the said patent document 1, force larger than the force in which a hinge pin tries to move to an axial direction is needed as a holding force in which a holding member hold | maintains a hinge pin in a proper position. In this case, if the force that the hinge pin attempts to move in the axial direction is greater than the holding force of the holding member, the hinge will unintentionally disassemble, so the holding force is set sufficiently large. There is a need. In particular, in construction machines, the force that the hinge pin tends to move in the axial direction may increase more than expected due to machine vibration or the like. For this reason, when trying to employ the hinge device of Patent Document 1 in a construction machine Therefore, it is necessary to set the holding force larger. On the other hand, when the hinge is disassembled, the hinge pin is pulled in the axial direction against the holding force of the holding member, so that a larger operating force than the sufficiently large holding force is required. However, there is a problem that when it is necessary to urgently remove the door or hatch of a construction machine in the event of a disaster, etc., it takes time and effort to disassemble the hinge device, and the hinge device cannot be quickly disassembled. Here, there is a problem to be solved by the present invention.

The present invention has been created in view of the above-described circumstances in order to solve these problems, and the invention of claim 1 connects the first member and the second member in a swingable manner. A hinge device, wherein the hinge device is attached to the first and second members, respectively, and the first and second plates are formed on the first and second plates and are adjacent to each other in the axial direction. A sleeve, and a hinge pin inserted through the first and second sleeves, and the first plate in a direction projecting from the end opposite to the second sleeve side end of the first sleeve. A restricting member that is movable between a restricting position that restricts the movement of the hinge pin and a release position that moves from the restricting position in a direction orthogonal to the axial direction of the hinge pin and allows the hinge pin to move in a direction protruding from the end. And the regulating member A pressing member that presses the second sleeve in a direction in which the hinge pin protrudes from the end portion is provided, while an urging ammunition for urging to the restriction position side and an operation portion for moving the restriction member from the restriction position to the release position are provided. When the restricting member is in the restricting position, the first and second plates are swingably connected by hinge pins inserted through the first and second sleeves, while the restricting member is in the releasing position. Then, the hinge pin pressed by the pressing member moves in a direction protruding from the end opposite to the second sleeve of the first sleeve, so that the hinge pin is detached from the second sleeve and the connection between the first and second plates is released. This is a hinge device.
According to a second aspect of the present invention, in the first aspect, the first sleeve, the second sleeve, and the hinge pin are provided in pairs, and the pair of first sleeves are provided in an axially spaced state. While the restriction member at the restriction position is disposed in the gap between the sleeves, the pair of second sleeves are provided adjacent to each other outward in the axial direction of the pair of first sleeves. The hinge device is characterized in that a hinge pin is inserted into each of the first and second sleeves.
A third aspect of the present invention is the hinge apparatus according to the first or second aspect, further comprising a hinge pin movement restricting means for restricting an axial movement range of the hinge pin relative to the first sleeve.
According to a fourth aspect of the present invention, in any one of the first to third aspects, the pressing member includes a pressing pin that is housed in the second sleeve and that abuts against the hinge pin, and covers the anti-first sleeve side end of the second sleeve. A pressing pin movement limiting means configured to limit the movement range of the pressing pin in the axial direction with respect to the second sleeve while being configured using a biasing ammunition machine interposed between the cover body and the pressing pin and pressing the hinge pin This is a hinge device characterized in that.

According to the first aspect of the present invention, when the hinge device is disassembled, the hinge pin is automatically removed from the second sleeve and the first plate and the first plate only by moving the restriction member from the restriction position to the release position. The connection between the two plates is released, and thus the hinge device can be easily disassembled without requiring a tool or the like. Moreover, since the restricting member is configured to move in a direction orthogonal to the axial direction of the hinge pin and displace from the restricting position to the release position, a force to move in the axial direction acts on the hinge pin as the hinge device swings. Even if the axial force does not act as a force for moving the restricting member at the restricting position to the release position side, the biasing force of the biasing ammunition for biasing the restricting member to the restricting position side is achieved. Can be set independently of the axial force acting on the hinge pin. As a result, the operating force for moving the restricting member from the restricting position to the releasing position can be lightened, and therefore, even when the hinge device is urgently required to be disassembled in the event of a disaster, for example, the light operating force can be reduced. The hinge device can be easily and quickly disassembled.
According to the second aspect of the present invention, the present invention can be implemented in a hinge device in which a pair of a first sleeve, a second sleeve, and a hinge pin are provided.
By setting it as invention of Claim 3, when a control member is made into a release position, a hinge pin can be reliably extracted from a 2nd sleeve. In addition, even if the connection between the first and second plates is released, the hinge pin does not fall off from the first sleeve, and thus the problem that the hinge pin is lost when the hinge device is disassembled can be prevented.
By setting it as invention of Claim 4, when a control member is made into a cancellation | release position, it can avoid that a pressing pin rushes in in a 1st sleeve. Further, even if the connection between the first and second plates is released, the pressing pin does not fall off from the second sleeve, and therefore, when the hinge device is disassembled, the hinge pin and the biasing ammunition constituting the pressing member are lost. It is possible to prevent malfunctions that occur.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a hinge device for swingably connecting a first member and a second member (the first member and the second member are not shown). The hinge device 1 is a first member. A first plate 2 attached to the second member, a second plate 3 attached to the second member, a pair of cylindrical first sleeves 4A, 4B formed on the first plate 2, and a second plate 3. A pair of cylindrical second sleeves 5A and 5B and a pair of hinge pins 6A and 6B are provided. In the drawing, 2a is an attachment hole for attaching the first plate 2 to the first member, and 3a is an attachment pin for attaching the second plate 3 to the second member.

  The pair of first sleeves 4A, 4B formed on the first plate 2 is provided in a state where there is a space S in the axial direction, and the pair of second sleeves 5A formed on the second plate 3; 5B is provided so as to be adjacent to each other outward in the axial direction of the pair of first sleeves 4A, 4B. The hinge pins 6A and 6B are inserted through the adjacent first and second sleeves 4A and 5A, 4B and 5B, respectively.

  Further, reference numeral 7 denotes a connection release portion provided on the first plate 2, and the connection release portion is configured by using a guide member 8, a restriction member 9, a release operation lever 10, a restriction member spring 11, and the like. Yes.

  The guide member 8 is for guiding the restricting member 9 to be slidably movable in a direction orthogonal to the axial direction of the hinge pins 6A and 6B, and has a hook shape in which the restricting member 9 is slidably engaged. The restricting member guide portion 8a and a pair of attachment pieces 8b and 8b fixed to the first plate 2 are integrally formed. The guide member 8 is such that the guide direction of the restricting member guide portion 8a is oriented in a direction perpendicular to the axial direction of the hinge pins 6A and 6B, and the leading end side of the restricting member guide portion 8a is the gap between the first sleeves 4A and 4B. The upper surface portion of the restricting member guide portion 8a is a cover portion 8c that extends further from the tip of the restricting member guide portion 8a and covers the gap S.

  On the other hand, the restricting member 9 has a two-stage rectangular parallelepiped shape in which a pin restricting portion 9a and a guide engaging portion 9b wider than the pin restricting portion 9a are integrally formed. By being engaged with the restricting member guide portion 8a of the guide member 8 and guided so as to be slidable, the pin restricting portion 9a protrudes from the distal end side of the restricting member guide portion 8a so as to be between the first sleeves 4A and 4B. It is configured to be freely movable between a restriction position located in the gap S and a release position that moves from the restriction position in a direction perpendicular to the axial direction of the hinge pins 6A and 6B and exits from the gap S. In a state where the restricting member 9 is located at the restricting position, both side surfaces of the pin restricting portion 9a face the opposite second sleeve side end portions of the first sleeves 4A and 4B and project from the end portions. The movement of the hinge pins 6A and 6B in the direction is restricted. On the other hand, the restricting member 9 at the release position allows the hinge pins 6A and 6B to move in a direction protruding from the end portion when the pin restricting portion 9a is retracted from the gap S. Further, a release operation lever (corresponding to the operation portion of the present invention) 10 that is gripped when the restriction member 9 is moved from the restriction position to the release position is fixed to the guide engagement portion 9b. The release operating lever 10 protrudes upward through a long hole 8d formed in the upper surface portion of the restricting member guide portion 8a. The elongated hole 8d is formed in an arrow shape on the release position side so that the operation direction of the release operation lever 10 when moving to the release position can be seen at a glance.

  Further, the regulating member guide portion 8a has a regulating member spring (corresponding to an urging ammunition for urging the regulating member of the present invention to the regulating position side) 11 that urges the regulating member 9 to the regulating position side. Decorated. Thus, the restricting member 9 is held at the restricting position by the urging force of the restricting member spring 11, while the restricting member 9 is moved to the releasing position side by holding the release operating lever 10. The member spring 11 can be positioned at the release position against the urging force of the member spring 11. Here, the urging force of the regulating member spring 11 is set to an urging force that holds the regulating member 9 in the regulating position without inadvertently moving to the release posture side due to the attachment direction of the hinge device 1 or vibration. ing. Further, the restricting member 9 at the restricting position is such that the stepped surface 9c between the pin restricting portion 9a and the guide engaging portion 9b abuts against the cylindrical outer peripheral portion of the first sleeves 4A and 4B, so that the tip end direction is further increased. Movement to is regulated.

  Here, in the state in which the restricting member 9 is located at the restricting position, as described above, the hinge pins 6A and 6B are restricted from moving in the direction of protruding from the opposite ends of the first sleeves 4A and 4B. However, in this state, the hinge pins 6A and 6B are inserted into the first and second sleeves 4A and 5A, 4B and 5B, and the first plate 2 and the second plate 3 are swingably connected. Is configured to do. On the other hand, in the state where the restricting member 9 is located at the release position, the hinge pins 6A and 6B are allowed to move in the direction protruding from the opposite end of the first sleeve 4A and 4B. The movement of 6A and 6B is allowed until the protruding tips of the pair of hinge pins 6A and 6B come into contact with each other, as will be described later, and when the protruding tips of the pair of hinge pins 6A come into contact with each other, the hinge pins 6A and 6B The opposite end of the first sleeve 4A, 4B is designed to be flush with the second sleeve side end of the first sleeve 4A, 4B (that is, the first sleeve 4A, 4B is anti-second from the axial center position of the gap S). The distance to the two sleeve side ends and the axial length of the hinge pins 6A, 6B are designed to be equal), so that the hinge pins 6A, 6B can be removed from the second sleeves 5A, 5B. It is configured. Then, when the hinge pins 6A and 6B are removed from the second sleeves 5A and 5B, the connection between the first plate 2 and the second plate 3 is released.

  Further, the first sleeves 4A and 4B are provided with guide holes 12A and 12B facing the axial direction of the hinge pins 6A and 6B, while the hinge pins 6A and 6B are movably engaged with the guide holes 12A and 12B. Matching guide pins 13A and 13B are projected. The guide pins 13A and 13B are brought into contact with both end portions of the guide holes 12A and 12B, so that the axial movement range of the hinge pins 6A and 6B with respect to the first sleeves 4A and 4B is limited. Thus, the hinge pins 6A and 6B are arranged such that the guide pins 13A and 13B abut on the opposite second sleeve side ends 12Aa and 12Ba of the guide holes 12A and 12B, so that the first sleeves 4A and 4B have the opposite second sleeve side. The movement in the direction protruding from the end is restricted, but at the position where the movement is restricted, the protruding tips of the pair of hinge pins 6A, 6B come into contact with each other, and the anti-projecting side ends of the hinge pins 6A, 6B And the second sleeve side ends of the first sleeves 4A and 4B are flush with each other so that the hinge pins 6A and 6B can be removed from the second sleeves 5A and 5B. Thus, the pair of hinge pins 6A and 6B can be removed from the second sleeves 5A and 5B without being offset. Further, since the guide pins 13A and 13B are engaged with the guide holes 12A and 12B, the hinge pins 6A and 6B are connected to the first sleeve 4A, even if the connection between the first plate 2 and the second plate 3 is released. It does not fall off from 4B. The guide holes 12A and 12B provided in the first sleeves 4A and 4B and the guide pins 13A and 13B protruding from the hinge pins 6A and 6B constitute the hinge pin movement limiting means of the present invention.

  On the other hand, the opposite end portions of the second sleeves 5A and 5B on the side opposite to the first sleeve are covered with the lids 14A and 14B, respectively, and the hinge pins 6A and 6B are provided inside the cylinders of the second sleeves 5A and 5B. The pressing members 15A and 15B that contact the hinge pins 6A and 6B, the pressing pins 15A and 15B, and the lid bodies 14A and 14B are used as pressing members that press in the direction protruding from the opposite second sleeve side ends of the sleeves 4A and 4B. Pin springs 16 </ b> A and 16 </ b> B interposed between the two are housed. The pressing pins 15A and 15B and the pin springs 16A and 16B constitute the pressing member of the present invention. Further, the pin springs 16A and 16B correspond to the urging ammunition for pressing the hinge pin of the present invention.

  The pressing pins 15A and 15B have the same diameter as the hinge pins 6A and 6B. When the first plate 2 and the second plate 3 are slidably connected, the pressing pins 15A and 15B and the hinge pins 6A and 6B are oscillated and supported. Configure the axis. The pin springs 16A, 16B are interposed between the lids 14A, 14B and the pressing pins 15A, 15B, and the hinge pins 6A, 6B are connected to the first sleeve 4A, via the pressing pins 15A, 15B. It is comprised so that it may press in the direction which protrudes from the anti-second sleeve side edge part of 4B.

  Further, the second sleeves 5A and 5B are provided with guide holes 17A and 17B facing the axial direction of the pressing pins 15A and 15B, while the pressing pins 15A and 15B are movable to the guide holes 17A and 17B. Engaging guide pins 18A and 18B are projected. The guide pins 18A and 18B are brought into contact with both end portions of the guide holes 17A and 17B, so that the axial movement range of the pressing pins 15A and 15B with respect to the second sleeves 5A and 5B is limited. . In this case, when the guide pins 18A and 18B are in contact with the first sleeve side ends 17Aa and 17Ba of the guide holes 17A and 17B, that is, when the pressing pins 15A and 15B are located closest to the first sleeve, The first sleeve side ends of the pins 15A and 15B and the first sleeve side ends of the second sleeves 5A and 5B are designed to be flush with each other, whereby the pressing pins 15A and 15B are arranged in the first sleeve 4A, It is configured not to rush into 4B. Further, since the guide pins 18A and 18B are engaged with the guide holes 17A and 17B, even if the connection between the first plate 2 and the second plate 3 is released, the pressing pins 15A and 15B are not connected to the second sleeve 5A. 5B is not dropped off. Further, since the pressing pins 15A and 15B do not fall off from the second sleeves 5A and 5B, the pin springs 16A and 16B interposed between the pressing pins 15A and 15B and the lid bodies 14A and 14B are also second. The sleeves 5A and 5B do not fall off. The guide holes 17A, 17B provided in the second sleeves 5A, 5B and the guide pins 18A, 18B protruding from the press pins 15A, 15B constitute the press pin movement restricting means of the present invention.

  In the hinge device 1 configured in this manner, when the release operating lever 10 is not operated, the restricting member 9 is held at the restricting position by the biasing force of the restricting member spring 11, and the first sleeve 4A, It faces the end portion on the side opposite to the second sleeve 4B. On the other hand, the hinge pins 6A, 6B are pressed in the direction protruding from the opposite end of the first sleeve 4A, 4B by the urging force of the pin springs 16A, 16B. The movement in the direction protruding from the end is restricted by abutting on. In this state, as described above, the hinge pins 6A and 6B are inserted into the first and second sleeves 4A and 5A, 4B and 5B so that the first plate 2 and the second plate 3 can swing freely. It is connected.

  On the other hand, when the connection between the first plate 2 and the second plate 3 is released, that is, when the hinge device 1 is disassembled, the release operation lever 10 is used to attach the regulating member 9 to the shafts of the hinge pins 6A and 6B. Move to the direction perpendicular to the direction to the release position. As a result, the restricting member 9 allows the hinge pins 6A and 6B to move in a direction protruding from the opposite ends of the first sleeves 4A and 4B. Thus, the hinge pins 6A and 6B are moved in a direction protruding from the end portions by the biasing force of the pin springs 16A and 16B, whereby the hinge pins 6A and 6B are pulled out from the second sleeves 5A and 5B, The connection between the plate 2 and the second plate 3 is released.

  In the present embodiment configured as described, the hinge device 1 is attached to the first plate 2 with the first and second plates 2 and 3 attached to the first and second members, respectively, and with a spacing S in the axial direction. A pair of first sleeves 4A and 4B formed, a pair of second sleeves 5A and 5B formed on the second plate 3 in a state adjacent to the axially outer sides of the first sleeves 4A and 4B, and 1. A pair of hinge pins 6A, 6B inserted through the first and second sleeves 4A, 5A, 4B, 5B are provided. Further, the first plate 2 has an anti-second sleeve of the first sleeves 4A, 4B. A restriction position that restricts the movement of the hinge pins 6A and 6B in a direction that protrudes from the edge part facing the side edge part, and a position that moves from the restriction position in a direction orthogonal to the axial direction of the hinge pins 6A and 6B. In the direction protruding from the part A restricting member 9 that is movable to a release position that allows movement of the hinge pins 6A and 6B, a restricting member spring 11 that biases the restricting member 9 toward the restricting position, and the restricting member 9 from the restricting position to the releasing position. A release operation lever 10 is provided for use in movement. On the other hand, inside the cylinders of the second sleeves 5A and 5B, the hinge pins 6A and 6B are pressed against the hinge pins 6A and 6B as pressing members that press the hinge pins 6A and 6B in the direction of protruding from the opposite end of the first sleeves 4A and 4B. Pressing pins 15A and 15B that are in contact with each other, and pin springs 16A and 16B that press the hinge pins 6A and 6B via the pressing pins 15A and 15B are internally provided. When the restricting member 9 is in the restricting position, the first plate 2 and the second plate 3 are swung by the hinge pins 6A and 6B inserted through the first and second sleeves 4A and 5A, 4B and 5B. On the other hand, when the restricting member 9 is in the release position, the hinge pins 6A and 6B pressed by the urging force of the pin springs 16A and 16B are connected to the second sleeve side end of the first sleeves 4A and 4B. By moving in the protruding direction, the hinge pins 6A and 6B are pulled out from the second sleeves 5A and 5B, and the connection between the first plate 2 and the second plate 3 is released.

  Thus, when the connection between the first plate 2 and the second plate 3 is released, the hinge pins 6A and 6B are simply moved by moving the restriction member 9 from the restriction position to the release position using the release operation lever 10. Is automatically moved by the urging force of the pin springs 16A and 16B to be removed from the second sleeves 5A and 5B, whereby the hinge device 1 is disassembled and the connection between the first plate 2 and the second plate 3 is released. Therefore, the hinge device 1 can be easily disassembled without requiring a tool or the like. In addition, since the restricting member 9 is configured to move in a direction orthogonal to the axial direction of the hinge pins 6A and 6B and displace from the restricting position to the release position, the hinge member 1 is pivoted to the hinge pins 6A and 6B. Even if a force to move in the direction acts, the force in the axial direction does not act as a force to move the restriction member 9 at the restriction position to the release position side. Regardless of the axial force acting on the hinge pins 6A and 6B, the urging force of the regulating member spring 11 that urges the regulating member 9 is inadvertently released due to the mounting direction or vibration of the hinge device 1 or the like. It is only necessary to set an urging force that does not move to. As a result, the operating force of the release operating lever 10 that moves the restricting member 9 from the restricting position to the releasing position can be reduced. For example, the hinge device 1 is used for attaching a door or hatch of a construction machine. Even when it is necessary to urgently remove the door or hatch in the event of a disaster, the hinge device 1 can be easily and quickly disassembled with a light operating force.

  Furthermore, in this case, as a hinge pin movement limiting means for limiting the axial movement range of the hinge pins 6A, 6B relative to the first sleeves 4A, 4B, guide holes facing the axial direction of the hinge pins 6A, 6B are provided in the first sleeves 4A, 4B. 12A and 12B are opened, and guide pins 13A and 13B that are movably engaged with the guide holes 12A and 12B project from the hinge pins 6A and 6B. Thereby, when the regulating member 9 is set to the release position, the pair of hinge pins 6A and 6B can be reliably removed from the second sleeves 5A and 5B without being offset.

  In this case, the hinge pins 6A and 6B are housed in the second sleeves 5A and 5B as the pressing members that press the hinge pins 6A and 6B in the direction in which the hinge pins 6A and 6B protrude from the opposite ends of the first sleeves 4A and 4B. The hinge pins 6A and 6B are interposed between the pressing pins 15A and 15B that contact the inner surface of the second sleeve 5A and the lids 14A and 14B that cover the opposite end portions of the second sleeves 5A and 5B and the pressing pins 15A and 15B. The pin springs 16A and 16B are used to press the pin, and the second sleeve 5A serves as a pressing pin movement limiting means for limiting the axial movement range of the pressing pins 15A and 15B relative to the second sleeves 5A and 5B. 5B is provided with guide holes 17A and 17B facing the axial direction of the pressing pins 15A and 15B, while the pressing pins 15A and 15B have front holes Guide holes 17A, the guide pin 18A engaging movably in 17B, 18B are projected. Thereby, when the restricting member 9 is set to the release position, it is possible to avoid the pressing pins 15A and 15B moving under the urging force of the pin springs 16A and 16B from entering the first sleeves 4A and 4B. .

  Furthermore, the axial movement range of the hinge pins 6A, 6B with respect to the first sleeves 4A, 4B is limited by the engagement between the guide holes 12A, 12B and the guide pins 13A, 13B, and the guide holes 17A, 17B Since the axial movement range of the pressing pins 15A, 15B with respect to the second sleeves 5A, 5B is limited by the engagement with the guide pins 18A, 18B, the first plate 2 and the second plate 3 are disassembled when the hinge device 1 is disassembled. The hinge pins 6A and 6B, the pressing pins 15A and 15B, and the pin springs 16A and 16B are not removed from the first and second sleeves 4A, 4B, 5A, and 5B even if the connection with the first and second sleeves is released. The two sleeves 4A, 4B, 5A, and 5B remain assembled. Thus, when the hinge device 1 is disassembled, the hinge pins 6A and 6B, the pressing pins 15A and 15B, and the pin springs 16A and 16B fall off from the first and second sleeves 4A, 4B, 5A, and 5B and are lost. Such problems can be reliably prevented, and the hinge device 1 can be easily reassembled.

  In addition, a restriction member spring 11 that biases the restriction member 9 toward the restriction position so that the restriction member 9 at the restriction position does not inadvertently move to the release posture side due to the attachment direction of the hinge device 1 or vibration. In addition, as described above, the hinge pins 6A and 6B, the pressing pins 15A and 15B, and the pin springs 16A and 16B do not fall off from the first and second sleeves 4A, 4B, 5A, and 5B. Therefore, the hinge device 1 can be used without any problem regardless of the direction in which the hinge device 1 is attached, and thus the hinge device 1 having high versatility can be obtained.

  Needless to say, the present invention is not limited to the above-described embodiment. For example, as a hinge pin movement limiting means for limiting the axial movement range of the hinge pin with respect to the first sleeve, a guide groove facing the hinge pin in the axial direction. On the other hand, a guide pin that movably engages with the guide groove can be projected from the first sleeve. Similarly, as a pressing pin movement limiting means for limiting the axial movement range of the pressing pin with respect to the second sleeve, a guide groove facing in the axial direction is formed on the pressing pin, while the second sleeve is movable to the guide groove. It is also possible to adopt a configuration in which a guide pin that engages with the projection is provided.

  In the hinge device of the above embodiment, a pair of the first sleeve, the second sleeve, and the hinge pin are provided. However, the present invention is not limited to this, and the first sleeve, the second sleeve, and the hinge pin are provided one by one. Of course, the present invention can be implemented even with the hinge device provided.

  The present invention can be used for various hinge devices that swingably connect two members, but is particularly useful when the hinge device needs to be urgently disassembled.
