Separation from the surface Operation by some as having a trigger 7 for operating the locking mechanism 6.

  In this example, the double door A has one and the other doors 1 and 2 suspended and supported by hinges on left and right pillars (not shown), and opens inward or outward. It is configured to open and close. At this time, in the door of this example configured using an aluminum extruded material, the end of the door 1 side in the surface of one door 1 is located on the inner side of the site of the vertical fence. For example, a lock-side arm 31 is disposed on the surface to be found, a handle 33 is disposed on the surface to be found on the road side, and a pivot shaft 32 having a square cross section, for example, is connected by a connecting shaft 34. The arm 31 or the handle 33 is rotated coaxially by rotating the arm 31 or the handle 33 so as to interlock with each other.

  Further, the end of the other door 2 on the side of the door-end, in this example, the same vertical wall, the same surface as the surface on which the arm 31 is installed, has a C-shaped cross section. A lock receiving side arm receiver 35 having a receiving groove is arranged, and in the present example, the other side of the roadside on the road side is paired with the handle 33 of the one door 1. A fixed handle 36 that cannot be rotated is disposed.

  The handles 33 and 36 use lever handles, and the arm 31 is provided with a handle portion of the same shape, which is aligned with the lever handle, on one side in the longitudinal direction so as to project integrally, and has an L shape at the tip of the free end. Thus, the arm 31 has a long bar shape that is approximately twice as long as the handles 33, 36.

  The arm 31 and the handle 33 in the double door 1 are respectively arranged with respect to the vertical saddle via a pedestal 37. The arm 31 and the handle 33 of the pedestal 37 have a cylinder on the handle 33 side. A thumb turn 39 for unlocking the lock 38 on the side of the site is arranged on the arm 31 side. The fixed handle 36 in the other door 2 is fixed so as not to be rotatable with respect to a similar pedestal 37, and the arm receiver 35 faces the pedestal 37 similar to the pedestal 37 of the arm 31 toward the site. The receiving grooves that are open upward so as to protrude are integrally arranged.

  The return-direction urging of the locking side arm 31 and the handle 33 is based on the rotation shaft 32 disposed on the back side of the arm 31 or the handle 33 and the rotation shaft 32 disposed on the double door 1. An arm biasing spring is interposed between the spring 4 and the bearing 4. In this example, the spring has standing parts at both ends, and the standing parts protrude outward. The spring case 43 accommodated in the spring case 43 is fixed to the rotating shaft 32 protruding from the rear side of the locking arm 31 and the double-opened one in the present example. The arm 4 is accommodated in a circular accommodating portion 41 of the bearing 4 disposed on the door 1 and the upright portion of the coil spring is disposed on a semicircular large-diameter portion 42 disposed on the inner wall of the bearing 4. 1 or the biasing force accumulated in conjunction with the rotation operation of the handle 33 as freely.

  That is, the spring case 43 that accommodates the coil spring is arranged in a donut shape with a semicircular slit disposed in the circumferential direction, and on the back side of the spring accommodating portion 44. In addition, it is formed with a connecting projection 45 having a square cross section and receiving the rotating shaft 32 inside, and an upright portion of the coil spring is disposed in the slit so that the coil spring is accommodated in the spring accommodating portion 44. It is.

  The bearing 4 of the rotating shaft 32 is fitted and fixed in an embedded manner at the upper and lower intermediate positions of the pedestal 37, accommodates a spring case 43, and in this example, the locking arm 31 is fixed. By inserting the pivot shaft 32 into the coupling protrusion 45 of the spring case 43 in a fitting manner and receiving the pivot shaft 32, the arm 31 or the handle 33 is pivoted to remove the pivot shaft 32 from the spring case 43. The spring case 43 is rotated in a state where one protruding protruding portion is held on one end wall of one of the pair defining the semicircular large diameter portion 42, and the urging force is accumulated in the coil spring. Thus, the arm 31 and the handle 33 are urged in the return direction, that is, in the direction in which the free end of the arm 31 engages with the arm receiver 35 and the lock 3 is locked.

  The locking side arm 31 urged in the return direction and the handle 33 that rotates coaxially with the locking side arm 31 are constrained and released by the lock mechanism 6, and the lock mechanism 6 A clutch 61 arranged coaxially with the locking arm 31 or the handle 33 and a lock plate 64 that can be engaged with and disengaged from the clutch 61 by an operation of separating the trigger 7 are formed. At this time, the trigger 7 is urged toward the door 2 on the other side of the double door to make the trigger 7 move away from the door 2 on the other side, thereby releasing the trigger 7. The contact operation, particularly the contact operation, is ensured, and the lock mechanism 6 is reliably operated.

  The clutch 61 is formed by a clutch plate in which a rectangular through-hole aligned with the rotation shaft 32 of the arm 31 is disposed at the center, and a meshing portion 62 formed by a recess formed in the outer periphery is disposed. A connecting projection 45 disposed on the spring case 43 is received in a rectangular through hole on the back surface of the bearing 4, and interlocked with the rotation of the spring case 43 by the rotation operation of the arm 31 or the handle 33. The clutch 31 is held in a rotating state by engaging a lock plate 64 with the meshing portion 62, and the arm 31 is held in a state in which the arm 31 is biased in the return direction. It is intended to be restrained.

The arrangement is performed so as to partially protrude.

  At this time, the bearing 4 integrally or integrally with the trigger box 5 in the present example formed as the block body of the present example is the same as the bearing 4 of the locking arm 31 and the handle 33 in the left and right inverted state. The locking arm 31 and the handle 33 can be installed so as to be rotatable in the reverse direction, and the locking lock 3 is assembled and formed using the bearing 4 so that the right and left hand can be freely set.

  That is, in this example, the bearing 4 in the block body has a circular accommodating portion 41 that accommodates the spring case 43 that receives the rotating shaft 32, and a pair of end walls that hold the standing portion of the spring case 43. When the semicircular large-diameter portion 42 is provided and the insertion hole through which the connecting shaft 34 is inserted is provided, the circular accommodating portion 41, the large-diameter portion 42 and its end wall are arranged symmetrically in the installed state of the bearing 4. Thus, the shape of the bearing 4 is set, and by rotating the bearing 4 on both doors of the double door A, the locking arm 31 and the handle 33 are rotated in the opposite directions. The lock receiving side arm receiver 35 can be engaged with the one side door. At this time, since the bearing 4 of this example is to be fixed with screws from the pedestal 37 in a state of being covered with the pedestal 37, screw holes for fixing the screws, for example, a pair of screw holes are also arranged symmetrically. In addition, the shape for fitting with the pedestal 37 is the same. Therefore, by using the bearing 4, an arbitrary door of the double door A is a double door 1 in which the lock-side arm 31 and the handle 33 are arranged, and the door constituting the double door A is defined as: The door 2 can be the other door 2 in which the lock receiving side arm receiver 35 is disposed. At this time, the lock receiving side arm receiver 35 has a C-shaped receiving groove, so that the left and right sides can be freely used. By using the bearing 4, it is possible to assemble and form the lock 3 according to the site's option and to install the left and right freely without preparing two types for the left and right sides.

  The trigger box 5 which is a block body integrated with the bearing accommodates the trigger 7 by rotatably mounting a trigger shaft 73 on the opposing inner wall thereof, and the trigger 7 according to the separating operation of the trigger 7. The lock plate 64 that slides so as to be engaged with and disengaged from the clutch 61 by the rotation of the clutch 61 is housed, and the lock plate 64 is biased toward the clutch 61 to engage the lock plate 64 when the clutch 61 is engaged. The trigger 7 protrudes from the trigger box 5 and accommodates a trigger spring 74 that biases the trigger 7 via a lock plate 64 so that the trigger 7 is immersed in the trigger box 5 when the clutch 61 is disengaged.

  The trigger 7 has one end in the longitudinal direction as a contact portion 71 with respect to the other door 2 and the other end in the longitudinal direction is a lock plate operating portion 72 having a cam function for transmitting the rotation of the trigger 7 to the lock plate 64. It is a block-like shape having a curved shape, and is provided with a trigger shaft 73 at a position displaced toward the lock plate actuating portion 72 at the other end in the longitudinal direction, and the trigger shaft 73 is disposed in the trigger box 5 The trigger box 5 is supported by a bearing (not shown) and is pivotally supported, and the trigger box 5 is disposed on the door 1 of the double door so as to partially protrude from the front end of the door. 7 is projected from the one door 1 of the double door to the other door 2 side of the double door so as to be separated from the other door 2 of the double door.

  The lock plate 64 includes a substrate 65, a pair of bent pieces 66 that are bent on one side of the substrate 65, and an inclined engagement piece 67 that is cut and raised in a through hole formed in the substrate 65. And a tongue piece portion 68 formed on one side of the substrate 66 through the step portion with the substrate 66 and having a circular arc recess matched to the clutch 61 at the tip and a meshing portion 69 projecting in a claw shape at the center thereof.
