Description

  The present invention relates to a hermetic handle having a function of hermetically locking a door body that can be opened and closed, such as an entrance / exit of various structures, an article entrance / exit port, a service port, or a fixed frame.

  In recent years, in the event of an emergency such as a flood or tsunami caused by a typhoon or torrential rain, doors are often installed at the doorway to prevent inundation of various structures from the doorway. However, as a mechanism for improving the sealing performance of the door body, for example, a sealing handle 90 shown in FIGS. 7 and 8 has been proposed.

  The sealing handle 90 shown in FIGS. 7 and 8 is used by being attached to the vicinity of the side edge portion 100b of the surface 100a of the door body 100, a fixing member 91 attached to the surface 100a of the door body 100, and the door. A main body 92 attached to the fixing member 91 in a state of being rotatable around an imaginary line X intersecting the surface 100a of the body 100; a lock member 93 provided at one end of the main body 92; And an operation arm 94 provided at the end.

  As shown in FIG. 7, in a state where the main body 92 is set so that the operation arm 94 and the lock member 93 are in the vertical direction, the side edge portion 100 b of the door body 100 is supported by the support member 103 erected at the doorway 102. When the operation arm 94 is rotated 90 degrees clockwise (arrow Y direction) about the imaginary line X after being accommodated in the door body accommodating groove 104 provided in FIG. A part contacts the inner side surface 104 a on the front side of the door housing groove 104.

  At this time, the door body 100 is pressed toward the inner side surface 104b on the back side of the door body accommodation groove 104 by the reaction force received by the lock member 93 from the inner side surface 104a. The attached packing 95 is compressed between the inner side surface 104 b and the sealability of the door body 100 with respect to the support member 103 can be ensured.

  Further, as a conventional technique related to the present invention, there is a hermetic handle device (see, for example, Patent Document 1) in which a door is brought into close contact with a fixed frame body such as a refrigerator main body and locked.

JP-A-8-209989

  The sealing handle 90 shown in FIG. 7 has a simple structure and is excellent in that the sealability between the door body 100 and the support member 103 can be maintained with a simple operation. In addition, the strength when a large pressing force (for example, a back surface pressing force such as a reverse water pressure) is applied may be insufficient. Such a problem also applies to the “sealed handle device” described in Patent Document 2.

  Further, in the “sealed handle device” described in Patent Document 2, the handle tip and the receiver slide each time the handle is rotated and locked / unlocked, so the operation exceeds the frictional resistance at that time. It is necessary to apply force, and operability is not good. Furthermore, since the sliding portion between the tip of the handle and the receiver is easily worn, there is a surface inferior in durability.

  Therefore, the problem to be solved by the present invention is that the locking / unlocking operation is easy, exhibits an excellent sealing property, has a high strength against a back pressing force such as a reverse water pressure, and has a good durability. To provide a handle.

A fixing member attached near the peripheral edge of the door body, a main body portion attached to the fixing member in a state of being rotatable around a first imaginary line intersecting the surface of the door body, and the first imaginary line Locking means attached to the main body in a state of being rotatable around a second imaginary line intersecting with
Similar to the main lock member that contacts the lock position of the inner surface while rotating along the inner surface of the door housing groove when the lock means rotates the main body around the first imaginary line. And a sub-lock member that abuts against a lock portion protruding from the fixing member while rotating along the fixing member.

  With such a configuration, the main body is rotated around the first imaginary line, and the main lock member and the sub lock means that are the lock means are connected between the inner side surface of the door body housing groove and the peripheral edge portion of the door body. Since the door can be locked and unlocked simply by engaging / disengaging between them, the operation is easy. In addition, during the locking / unlocking operation, the main lock member moves while rotating along the inner surface of the door housing groove, and the sub-lock member moves while rotating along the fixed member. Is extremely small, has excellent operability, and has low wear, so durability is also good. Furthermore, when in the locked state, the main lock member abuts on the inner surface of the door body housing groove, and the sub-lock member abuts on the lock portion of the fixing member, whereby the door body is firmly locked, Excellent sealing performance and high strength against reverse pressure such as reverse water pressure.

  Here, in the fixing member, it is desirable to provide an inclined surface that forms an upward slope toward the lock portion in a region where the auxiliary lock member moving toward the lock portion can contact.

  With such a configuration, when the sub-lock member moves toward the lock portion of the fixing member in the process of the locking operation, it becomes possible to reach the lock portion while rotating along the inclined surface. Operability at the time of locking is improved.

  On the other hand, including the state in which the locking means is engaged between the inner surface of the door body housing groove and the peripheral edge portion of the door body housed in the door body housing groove, It is desirable that normal rotation and reverse rotation are possible around the first imaginary line.

  With such a configuration, the rotation direction of the main body at the time of locking / unlocking is not limited to one pattern (for example, locking by right rotation and unlocking by left rotation), so that the operator can operate easily. It can be rotated and is effective in improving operability. Moreover, since one type of sealing handle can be attached to either the left side or the right side of the door body, versatility is enhanced.

  Further, it is desirable that an operation arm for rotating the main body portion around the first imaginary line is provided on the main body portion.

  With such a configuration, the locking / unlocking operation can be performed with a small operating force, so that the operability is further improved. Further, the lever principle can increase the contact pressure of the main lock member with respect to the inner surface of the door housing groove and the contact pressure of the sub lock member with respect to the lock portion of the fixing member. It is effective for improving the performance.

  According to the present invention, it is possible to provide a hermetic handle that is easy to lock and unlock, exhibits excellent hermeticity, has high strength against back pressing force such as reverse water pressure, and has good durability.

  Hereinafter, based on FIGS. 1-6, the sealing handle 10 which is embodiment of this invention is demonstrated. As shown in FIGS. 1 to 5, the sealing handle 10 of the present embodiment is used by being attached to the vicinity of the left edge 30 a that is a part of the peripheral edge of the door body 30, and a support member that is erected on the base surface. The lock means 13 is engaged between the inner side surface 41a of the door body housing groove 41 provided in the door 40 and the left side edge 30a of the door body 30 housed in the door body housing groove 41 so as to be able to advance and retreat.

  The sealing handle 10 is a fixing member that is rotatable around a fixing member 14 attached near the left edge 30a of the door body 30 and a first imaginary line L1 intersecting (orthogonal) with the surface 30f of the door body 30. 14 and a lock means 13 attached to the main body 15 so as to be rotatable around a second virtual line L2 intersecting (orthogonal) with the first virtual line L1. . The main body portion 15 is provided with an operation arm 16 for rotating the main body portion 15 around the first virtual line L1. The lock means 13 and the operation arm 16 are provided at positions 180 degrees symmetrical with respect to the first virtual line L1. The fixing member 14 is fixed to the surface 30 f of the door body 30 by a plurality of screws 17.

  When the main body 15 is rotated around the first imaginary line L1 as the lock means 13, the main lock member 11 contacts the lock position 41x of the inner side surface 41a while rotating along the inner side surface 41a of the door body housing groove 41. And a sub-lock member 12 that abuts against a lock portion 14 a protruding from the fixing member 14 while rotating along the fixing member 14. The main lock member 11 and the sub-lock member 12 are substantially cylindrical members, and are adjacent to the shaft body 18 provided in the main body 15 so as to be coaxial with the second virtual axis L2 in an independently rotatable manner. It is arranged to fit.

  The main lock member 11 is disposed on the distal end side (the side far from the first imaginary line L1) of the shaft body 18, and the sub-lock member 12 is disposed on the proximal end side (the side close to the first imaginary line L1) of the shaft body 18. ing. A tapered conical surface 11 a is provided on the distal end side of the main lock member 11.

  In addition, as shown in FIGS. 1 and 5, in the fixing member 14, two slopes that form an upward slope toward the lock portion 14 a in a region where the auxiliary lock member 12 that moves toward the lock portion 14 a can come into contact. A surface 14b is provided. The two inclined surfaces 14b are formed so as to be symmetric with respect to the lock portion 14a.

  The main body portion 15 is rotatably supported by a shaft body 19 provided upright on the fixing member 14 so as to be coaxial with the first imaginary line L1. As shown in FIG. 1, when the operation arm 16 is rotated forward / reversely about the first virtual line L1 (shaft body 19), the main body 15 also rotates forward about the first virtual line L1 (shaft body 19). In reverse, the lock means 13 rotates between the unlocking positions P1 and P3 and the locking position P2. Therefore, the lock means 13 is engaged between the inner side surface 41a of the door body housing groove 41 and the left edge 30a of the door body 30 housed in the door body housing groove 41 (locking position P2). The main body 15 can be rotated forward and backward within the range of the unlocking positions P1 and P3 around the first imaginary line L1.

  As shown in FIGS. 2 and 4, packing 31 is provided along the left side edge 30 c of the back surface 30 b of the door body 30, and the left side edge surface of the door body 30 is placed in the door body accommodation groove 41 of the support member 40. An auxiliary support member 42 that contacts 30d is disposed.

  As shown in FIG. 1, in the sealing handle 10 in which the locking means 13 is in the unlocked position P1 (or P3), the operation arm 16 is grasped by hand, and the main body 15 is rotated 90 degrees around the first imaginary line L1 ( 2 to 5, the main lock member 11 comes into contact with the inner side surface 41 a of the door housing groove 41 and rotates along the inner side surface 41 a as shown in FIGS. 2 to 5. The sub-lock member 12 similarly contacts the inclined surface 14b of the fixing member 14, contacts the lock portion 14a while rotating along the inclined surface 14b, and the door body 30 is locked. .

  At this time, due to the reaction force received by the main lock member 11 from the inner side surface 41 a on the front side of the door body accommodation groove 41, the door body 30 is pressed toward the inner side surface 41 b on the back side of the door body accommodation groove 41. Is compressed, the door body 30 and the door body housing groove 41 are in a sealed state.

  In this way, the main lock member 11 abuts on the lock position 41x of the inner side surface 41a of the door body housing groove 41 simply by operating the operation arm 16 to rotate the main body 15 around the first imaginary line L1. At the same time, the sub-lock member 12 abuts against the lock portion 14a of the fixing member 14, whereby the door body 30 is firmly locked. The strength when high back pressure such as water pressure in the direction is applied is also high.

  Further, if the main arm 15 is rotated by performing the reverse operation to the operation arm 16, the main lock member 11 is detached from the inner side surface 41 a of the door body housing groove 41, and the sub-lock member 12 is Since the door 30 is released from the locked state by being detached from the lock portion 14a of the fixing member 14, the opening / closing operation is extremely easy.

  During the locking / unlocking operation, the main lock member 11 moves while rotating along the inner side surface 41a of the door housing groove 41, and the sub-lock member 12 rotates along a part of the fixing member 14. Since it moves, the frictional resistance is extremely small, the operability is excellent, and the wear is low, so that the durability is also good.

  In the fixing member 14, an inclined surface 14 that forms an upward slope toward the lock portion 14 a is provided in a region where the secondary lock member 12 that moves toward the lock portion 14 a can come into contact. When the lock member 12 moves toward the lock portion 14a of the fixing member 14, it can reach the lock portion 14a while rotating along the inclined surface 14b, so that it is not only excellent in operability during locking but also unlocked. Operation is also smooth.

  Further, since the operation arm 16 for rotating the main body portion 15 around the first imaginary line L1 is provided in the main body portion 15, it is possible to perform the locking / unlocking operation with a small operation force, so that the operability is improved. It is good. Further, according to the lever principle, the contact pressure of the main lock member 11 with respect to the inner side surface 41a of the door body housing groove 41 and the contact pressure of the sub lock member 12 with respect to the lock portion 14a of the fixing member 14 can be increased. This is effective for improving the sealing performance of the door body 30.

  The main body 15 is in a state in which the locking means 13 is engaged between the inner side surface 41a of the door body housing groove 41 and the left edge 30a of the door body 30 housed in the door body housing groove 41 (locking). Including the position P2), normal rotation and reverse rotation are possible within the range of the unlocked positions P1 and P3 around the first imaginary line L1.

  For this reason, the rotation direction of the main body 15 at the time of locking / unlocking is not limited to one pattern (for example, locking by right rotation and unlocking by left rotation), so that the operator can operate the operation arm 16 in a direction that is easy to operate. It can be rotated and has good operability. Also, one kind of the sealing handle 10 is attached to the left edge 30a of the door 30 as shown in FIG. 4, or is attached to the right edge 30e of the door 30 as shown in FIG.
