Description

  The present invention relates to a weathertight door for a ship.

  A weather-tight door of a ship blocks the entry of wind and rain from the outside when closed, but may be opened when there is no wind or rain. The weather-tight door maintains an open state by using a hooking means including a hook provided on one side of the ship side or the door side and a hook receiver provided on the other side of the ship side or the door side. The hook and the hook receiver may require a special structure or configuration suitable for a ship or a weather-tight door, or may be installed at various positions. In addition, since the hook and hook holder are positioned and welded to the weathertight door that has been installed, the weathertight door is welded and burned, spatter scattered, and forced to repaint. There was a problem.

  The weather-tight door disclosed in Patent Document 1 is a module specification in which the door frame and the door body are assembled in advance at the factory via hinges, and is attached to the door-attached eye plate and door frame. The eye plate with the door and the stopper eye plate after adjusting the angle of the stopper eye plate with respect to the edge material eye plate. The door body in the open state is fixed at an arbitrary angle by connecting the pin holes (pin holes) provided at the end portions of the doors and inserting the stopper pins (Patent Document 1 and Claim 1). [Claim 2] and others).

  The weather-tight door disclosed in Patent Document 1 is such that the eye plate with the door and the stopper eye plate are in a relationship of a hook and a hook receiver provided in advance on the door frame and the door body. Eliminates installation work by welding. This eliminates the need for welding burn, spatter adhesion and repainting of the weathertight door, and has the effect of reducing the burden of on-site work. Further, since the opening angle (opening angle) of the door body can be determined freely, it is assumed that there is an effect that setting of the installation position of the hook and the hook receiver becomes unnecessary (Patent Document 1, [0010], etc.).

JP 2011-218858

  The weathertight door disclosed in Patent Document 1 is a module specification in which a door frame and a door main body are assembled, and an edge material eye plate is attached to the door frame, and an eye plate with a door is attached to the door main body in advance. Thus, the installation work involving welding of the hook and hook receiver after the weathertight door is attached is eliminated. This is excellent in that it does not require welding burn, spatter adhesion, or repainting of the weathertight door, and reduces the burden of on-site work. However, the weather-tight door disclosed in Patent Document 1 has the following problems.

  A weathertight door disclosed in Patent Document 1 is a stopper in which an eye plate with a door and an edge material eye plate that are adjacent to each other with a hinge of a door body fixed and supported at an arbitrary angle with respect to the edge material eye plate. Since it is connected via the eye plate, the opening angle of the door body can be adjusted by changing the angle of the stopper eye plate relative to the edge eye plate. The door body opening angle is changed by changing the angle of the stopper plate relative to the edge eye plate. However, because the eye plate with the door and the edge eye plate are too close together with the hinge of the door body, if the angle of the stopper eye plate changes a little, the opening angle of the door body changes greatly, and the target opening angle is reached. It is not easy to change.

  The opening angle of the door body is set according to the angle of the stopper eye plate with respect to the edge material eye plate. If the angle of the stopper eye plate changes, the opening angle of the door body may change. In order to change the opening angle of the door body, as described above, the angle of the stopper eye plate with respect to the edge material eye plate is changed. Therefore, when the angle of the stopper eye plate is insufficiently fixed, the angle of the stopper eye plate is It is also possible that it will change. In the worst case, if the stopper eye plate is detached from the edge material eye plate, the door body becomes free, which is very dangerous.

  Thus, the weathertight door disclosed in Patent Document 1 is excellent in that it can eliminate the installation work involving welding and further adjust the opening angle of the door body by changing the angle of the stopper eyeplate with respect to the edge eyeplate. However, there is a problem that it is difficult to adjust the opening angle of the door body, the angle of the stopper eye plate with respect to the edge material eye plate may be shifted, or the stopper eye plate may be detached from the edge material eye plate. Therefore, like the weathertight door disclosed in Patent Document 1, in order to eliminate installation work that involves welding, a hook and a member equivalent to a hook receiver are attached in advance to the weathertight door of the module specification in which the door frame and the door body are assembled. In order to eliminate the possibility of the door body being in a free state while allowing the opening angle of the door body to be adjusted, studies were made.

  What was developed as a result of the study is a weather-tight door with a modular specification in which the door frame and the door body are assembled in advance via a hinge. The base end of the door frame is connected to the door frame in a free state. It has a hook that allows the horizontal angle of the key to be freely adjusted, and a hook holder that is fixed to the door body and has a plurality of key holders that are located in different horizontal positions. Open the door body and attach the hook to the hook receiver. When hooking, the front key part is hooked to the selected key receiving part of the hook receiver, and the horizontal angle of the front key part with respect to the door frame is changed, so that the door body held by the hook and hook receiver is held. It is a weathertight door characterized by adjusting the opening angle.

  The weather-tight door of the present invention is a module specification in which a door frame and a door body are assembled in advance, and a hook and a hook receiver whose mutual positional relationship is specified via a hinge are assigned to the door frame and the door body, respectively. By attaching, it is not necessary to attach the hook and hook receiver after installation. Since the hook and the hook receiver of the present invention are provided with a plurality of key receiving portions on the hook receiving, the hook is supported via the hook receiving by selecting the key receiving portion with which the front end key portion is engaged. The opening angle of the door body can be adjusted.

  If the hook is connected to the door frame via a base end that can be turned up and down and left and right, except for play during assembly, and the horizontal angle of the tip key can be changed freely, the tip key In addition to the rod body provided with the portion, it may be configured by a plate-like body or a block body, and the entire configuration connecting the base end portion and the distal end key portion may be linear or curved. The hook receiver only needs to have a plurality of key receiving portions that are inserted from above to engage the tip key portion in the horizontal direction. The key receiving portion of the present invention may have any structure as long as the front end key portion of the hook can be hooked in the horizontal direction, but a hole opened upward (a hole penetrating vertically) so that the front end key portion can be inserted from above. Alternatively, a hole (a hole that does not penetrate vertically and is closed at the bottom) is preferable.

  When the hook is connected to the door frame in a free state by passing the hook side ring provided on the base end and the door frame side ring provided on the door frame to the inner peripheral side of each other, The degree of freedom to rotate both in the direction and in the vertical direction is obtained, and the key receiving part of the hook receiver can be selected to engage the tip key part from above. The “hook side ring” or “door frame side ring” is an annular member that forms an inner peripheral side surrounded by a bent rod body or plate body or a plurality of rod bodies or plate bodies. The door frame side ring is hooked with each other through the hook side ring on the inner peripheral side of the door frame side ring. For example, it is possible to disclose a combination in which a base end portion of a hook formed of a rod body is bent to form an annular hook side ring, and a U-shaped rod body having both ends fixed to a door frame by welding is used as a door frame side ring.

  The hook side ring or door frame side ring preferably has a configuration in which the range surrounded by the rod body or plate body is completely closed. However, if the connection relationship between the hook side ring and the door frame side ring is not broken, a gap is partially formed. An open configuration may be used. For example, one or the other of “hook side ring” or “door frame side ring” may have a configuration in which a linear rod is installed on a pair of flanges (plate members) provided on the door frame or the door frame. If it does not collapse, the erected rod body may be cantilevered by one flange, and there may be a gap in part.

  When the hook receiver has a plurality of key receiving portions arranged on the circumference around the rotation center of the hinge, the locus of the key receiving portion when the door body is opened and closed is centered on the rotation center of the hinge. Since they are arranged on the circumference, the key receiving portion to be engaged can be selected without changing the horizontal angle of the front end key portion of the hook so much, and the opening angle of the door body can be easily changed. There may be two or more circumferences around which the key receiving portions are arranged centering on the rotation center of the hinge. In this case, two or more key receiving portions having slightly different angles around the rotation center of the hinge can be arranged on different circumferences, and the opening angle of the door body can be finely adjusted.

  The key receiving portion provided in the hook receiver may have any configuration as long as the tip key portion of the hook can be hooked in the horizontal direction. For example, if the hook receiver has a configuration in which a plurality of key receiving portions each formed of a hole penetrating vertically are provided, it is possible to perform a simple operation that can be hooked in the horizontal direction simply by inserting the tip key portion of the hook from above, Prevents dirt and water from accumulating in the area. In this case, if the hook receiver is made of a plate material, it is easy to provide a key receiving portion consisting of a through-hole. However, if the hole can penetrate, the hook receiver may be made of a thick plate material or block.

  The weathertight door of the present invention, like the weathertight door disclosed in Patent Document 1, does not require installation work involving welding of hooks and hook receivers, and allows the door body to be in a free state while allowing the door body opening angle to be adjusted. There is no fear of becoming. This is because the base end portion is connected to the door frame in a free state, the front end key portion with respect to the door frame has a free horizontal angle, and a plurality of keys fixed to the door body and having different horizontal positions. This is an effect of a combination with a hook receiver provided with a receiving portion.

  In addition, the weather-tight door of the present invention has fewer parts than the weather-tight door disclosed in Patent Document 1, and the structure is simplified, so it is considered that the manufacturing cost can be reduced. Furthermore, unlike the weathertight door disclosed in Patent Document 1, the weathertight door of the present invention does not require the door body opening angle to be set in advance, and after opening the door body, the door body opening angle is set. Can be adjusted at intervals according to the key receiver. And the door main body which adjusted the opening angle does not have a possibility that it may be in a free state unexpectedly by engagement of a hook and a hook receptacle, and can maintain the said opening angle stably.

  The connection by the hook side ring and the door frame side ring gives the hook a degree of freedom of rotation in the horizontal direction and the vertical direction, and makes it easy to engage the tip key part with the key receiving part of the hook receiver. The hook-side ring and the door frame-side ring are connected when the pivot center of the hook that pivots in the horizontal direction and the vertical direction is defined as one point, and when the tip key part of the hook is engaged with the key receiving part of the hook receiver. The opening angle of the door body can be uniquely specified. As a result, the door body opening angle can be changed without much changing the horizontal angle of the hook end key part by simply arranging a plurality of key receiving parts on the circumference around the rotation center of the hinge. Can be easily changed, and if the circumference is set to 2 or more, the opening angle can be finely adjusted.

  The key receiving part provided in the hook receiver is a hole that penetrates up and down, so that the hook key part can be securely hooked in a horizontal direction with simple operation, and dust and water are not easily collected. It brings about the effect of making it possible to suppress or prevent corrosion and rusting that cause deterioration of the strength of the receiver. Since the hook receiver has a side surface as a strength member for maintaining the opening angle of the opened door body together with the hook, the effect of suppressing or preventing corrosion and rusting is very important.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The weathertight door of the present invention is configured with a module specification in which the door frame 1 and the door body 2 are assembled in advance via, for example, a hinge 21 (see FIG. 1). In the weathertight door of this example, the hinge 21 has two upper and lower stages, but three or more stages may be provided. The hook 3 and the hook receiver 4 for adjusting the opening angle of the door body 2 are provided between the upper and lower hinges 21 of the upper and lower hinges 21.

  As shown in FIGS. 1 to 3, the door frame 1 is a substantially rectangular frame configured by bending a metal angle member in which a seal pressure contact strip 13 protrudes toward the seal 22 of the door body 2, The corners are smoothly curved to eliminate the corners where stress is concentrated, thereby increasing the rigidity. The door body 2 is attached so as to close a substantially rectangular opening surrounded by the door frame 1 from the outside, is supported by a hinge 21 provided in the door frame 1 and can be opened and closed freely.

  The door frame 1 is fitted into an opening provided in the hull wall surface 5 and welded over the entire circumference. Since the weathertight door of the present invention is a module specification in which the door body 2 is assembled to the door frame 1, the installation work is completed when the door frame 1 is attached to the hull wall surface 5. In addition, the door frame 1 of this example has door frame side pipe receivers 121 and 121 for holding the door frame side clip handle operation pipe 12 detachably on the outer side of the ship (the front side in FIG. 1). A pair of upper and lower is provided at the position. If necessary, the door frame side clip handle operation pipe 12 is removed from the door frame side pipe receivers 121 and 121 and fitted to the clip handle 24 on the outside of the ship, thereby extending the clip handle 24 and facilitating the rotation operation. To do.

  The door body 2 is a metal substantially rectangular plate surface that is attached to the door frame 1 so as to be opened outward by the upper and lower hinges 21 so as to block the opening of the door frame 1 from the outside. A seal 22 is fitted into a U-shaped seal fitting frame 221 provided along the left and right sides, and two upper and lower reinforcing bars 23 are bridged between the left and right seal fitting frames 221. Welded inside. The seal 22 is pressed against the seal pressure contact strip 13 of the door frame 1 in a state in which the door body 2 is closed, thereby exhibiting weather tightness.

  The pressure contact of the seal 22 against the seal pressure contact strip 13 is realized by pressing the door main body 2 against the door frame 1 by tightening the clip handle 24 arranged at the corner of the door main body 2 and the vertical middle position. The clip handle 24 can be rotated either inside or outside the door body 2. The door main body 2 of this example is provided with a door main body operation handle 26 for opening / closing operation on the outer side (front side in FIG. 1) at a position opposite to the hinge 21 and on the inner side of the ship (FIG. 1). A pair of upper and lower door body side pipe receivers 251 that detachably hold the door body side clip handle operation pipe 25 is provided at the middle of the left and right and slightly lower than the middle of the upper and lower sides. If necessary, the door body side clip handle operation pipe 25 is removed from the door body side pipe receivers 251 and 251 and fitted to the clip handle 24 on the inside of the ship, so that the clip handle 24 can be extended to easily rotate. To do.

  The hook 3 and the hook receiver 4 are provided at the same height as the upper reinforcing bar 23 provided in the door body 2. The hook 3 is attached to a metal door frame side ring 11 fixed to the door frame 1 with a hook side ring 31 serving as a base end portion, and is attached to the door frame 1 so as to be rotatable up and down and left and right. An end portion of the L-shaped metal rod that is bent with respect to the main body portion is the tip key portion 32. For convenience of explanation, the hook 3 in each figure is shown in a horizontal posture with the tip key portion 32 facing downward, but the hook 3 in a free state is in a suspended posture with the tip key portion 32 horizontally oriented.

  The hook 3 has only a base end portion (hook side ring 31) connected to the door frame 1 in a free state and has a distal end key portion 32, and is configured by bending one metal bar as in this example. In addition, for example, the base end portion (hook side ring 31), the distal end key portion 32, and the main body connecting the both may be separate components and assembled. Since the hook 3 restrains the door body 2 at a specific opening angle, the hook 3 needs to withstand pulling or compression due to the movement of the door body 2 to be opened and closed. From this, when the hook 3 is formed by bending a metal rod as in this example, the rod is preferably made of, for example, SS400, and the rod has a diameter of 13 mm to 16 mm.

  The hook receiver 4 is a deformed pentagonal metal plate material having a step on one side (see FIG. 3), and the long side adjacent to the one side is arranged in a direction perpendicular to the door body 2. The door body 2 is fixed by welding. The hook receiver 4 of this example is provided with key receiving portions 41, 42, 43, 44, 45 each having a through hole into which the tip key portion 32 of the hook 3 is inserted from above, and the selected key receiving portions 41, 42, By inserting the tip key part 32 of the hook 3 into the 43, 44, 45 from above, the opening angle of the door body 2 is set to 90 degrees, 120 degrees, 135 degrees, 150 degrees, and 170 degrees. The open state can be maintained.

  The hook receiver 4 only needs to be provided with key receiving portions 41, 42, 43, 44, 45 that can be engaged with the tip key portion 32 of the hook 3, and a key holder that is a hole penetrating through a metal plate material as in this example. In addition to the configuration in which the portions 41, 42, 43, 44, and 45 are provided, a configuration in which a key receiving portion that does not penetrate with a rigid metal block may be provided. The key receiving portions 41, 42, 43, 44, and 45 of the through holes are excellent in that dust and water are not collected inside, and corrosion and rusting that cause deterioration of the strength of the hook receiver 4 can be suppressed or prevented. . Here, the hook receiver 4 is required to endure pulling or compression due to the movement of the door body 2 to be opened and closed like the hook 3 by engaging with the hook 3. From this, when the hook receiver 4 is made of a metal plate material as in this example and the key receiving portions 41, 42, 43, 44, and 45 of the holes are further provided, the metal plate material is made of, for example, SS400, The thickness is preferably 6 mm to 9 mm.

  A key receiving part 41 with a door body opening angle of 90 degrees and a key receiving part 43 with the opening angle of 135 degrees are on an inner circle 211 centering on the rotation center 213 of the hinge 21, and the key A receiving portion 43 is provided near the door body 2. Further, the key receiving part 42 whose door body opening angle is 120 degrees, the key receiving part 44 whose opening angle is 150 degrees, and the key receiving part 45 whose opening angle is 170 degrees are the rotation center of the hinge 21. The key receiving portion 45 is located near the door main body 2, and the key receiving portion 44 and the key receiving portion 42 are provided farthest from the door main body 2.

  The key receiving portions 41, 42, 43, 44, 45 in this example are provided separately in two inner circles 211 and 212 around the rotation center 213 of the hinge 21. For example, all may be provided on the same circumference. However, it is practically difficult to arrange the key receiving portions 41, 42, 43, 44, and 45 on the same circumference because they interfere with each other. From this, it is preferable to arrange the plurality of key receiving portions 41, 42, 43, 44, 45 on a plurality of circumferences around the rotation center 213 of the hinge 21 as in this example.

  The maintenance of the open state of the door body 2 by the hook 3 and the hook receiver 4 being engaged will be described. When the tightening of the clip handle 24 to the door frame 1 is loosened, the door body 2 can be opened outward by holding the door body side handle 25 (opening in front of the paper surface in FIG. 1). As shown in FIG. 4, when the door body 2 is at an opening angle of 90 degrees, the key receiving portion 41 of the hook receiver 3 in which the tip key portion 32 of the hook 3 is displaced with the door body 2 and changed its direction. Insert from above. In this way, the hook 3 and the hook receiver 4 are engaged with each other to restrict the opening and closing of the door body 2, and the open state of the door body 2 is maintained while maintaining the opening angle of 90 degrees.

  Similarly, as shown in FIG. 5, when the distal end key portion 32 of the hook 3 is inserted into the key receiving portion 42 of the hook receiving 3, the door body 2 is maintained in an open state with an opening angle of 120 degrees. Further, as shown in FIG. 6, when the front end key portion 32 of the hook 3 is inserted into the key receiving portion 43 of the hook receiving portion 3, the door main body 2 is maintained in an open state with an opening angle of 135 degrees. Further, as shown in FIG. 7, when the front end key portion 32 of the hook 3 is inserted into the key receiving portion 44 of the hook receiving portion 3, the door main body 2 is maintained in an open state with an opening angle of 150 degrees. As shown in FIG. 8, when the front end key portion 32 of the hook 3 is inserted into the key receiving portion 41 of the hook receiving 3, the door body 2 is maintained in an open state with an opening angle of 170 degrees.

  When it is desired to change the opening angle of the door body 2, the key receiving portions 41, 42, 43, 44, 45 into which the tip key portion 32 of the hook 3 is inserted are changed. Here, as can be seen by comparing FIG. 5 (opening angle 90 degrees) to FIG. 8 (opening angle 170 degrees), the door body 2 has a large opening angle change in the range of 80 degrees. The angle at which the distal end key portion 32 is inserted into the key receiving portions 41, 43 (approximately 16 degrees clockwise from the lower side in each figure) and the angle at which the distal end key portion 32 is inserted into the remaining key receiving portions 42, 44, 45 (each figure) It changes only in the range of about 20 degrees, such as about 36 degrees clockwise starting from the middle and lower, and two choices. As described above, it is understood that the operation range of the hook 3 is narrower than the opening angle of the door body 2 and that there is an advantage that the opening angle of the door body 2 can be adjusted only by moving the hook 3 slightly.
