Description

  The present invention relates to a push-pull lock used for a residential door or the like.

Apartment houses such as condominiums are often western-style in interior, and an opening door is provided at the entrance of each room. In addition, in newly-built detached houses, westernization has progressed, and swing doors are often used at the entrances and exits of rooms.
Conventionally, a rotary handle lock has been used for such hinged doors. However, in recent years, the handle is operated indirectly by pushing the handle (operating part) on one side of the door in accordance with the opening / closing direction of the door. A push-pull lock is used that opens the door by pushing and opens the door by pulling the door indirectly by pulling the handle on the other side of the door.

The push-pull lock is different from the rotary handle lock that rotates the handle to open the door and the mechanism for operating the latch. In the push-pull lock, a mechanism for operating the latch by the handle is disclosed in, for example, Patent Document 1, Patent Document 2, and Patent Document 3.

  By the way, from the viewpoint of safety and design, there is a demand for eliminating protrusions such as handles on the indoor door. Since the push-pull lock is a type in which the latch is retracted by pushing or pulling the operation part (handle or the like), the degree of protrusion of the operation part from the door can be reduced, and this demand can be met. . Such an attempt to reduce the degree of protrusion of the operation unit from the door is disclosed in Patent Document 2, for example.

  However, as disclosed in Patent Documents 1 to 3, the push-pull lock is usually arranged so that the operation part sandwiches the lock box on both sides of the door, and the push-pull lock is pushed from both sides of the lock box to the operation part. The pulling action is transmitted to the lock box. Therefore, in order to eliminate the protrusion of the operation unit from the door and make the operation unit substantially the same surface as the surface of the door, a door having a thickness that can accommodate these must be selected, and a door that can be attached is provided. There is a problem that it is extremely limited.

However, the positional relationship between the lock box 2, the pull-side handle portion 3, and the push-side handle portion 4 can be more strictly determined by making the gap 72 long enough to be fitted with the positioning portion 47 and the positioning portion 62. Can be prescribed.

Next, the operation of the push-pull lock 1 will be described with reference to FIG.
In the push-pull lock 1, when the pull-side handle 42 is pulled out from the recess 45 (operated in the direction of the arrow M <b> 1 in FIG. 10), the push-out portion 52 integrated with the pull-side handle 42 rotates to receive the pressure receiving portion. 56 is rotated in the direction opposite to the pushing portion 52 (arrows M2 and M3 in FIG. 10). Then, the pulling side pressing portion 43 integrated with the pressure receiving portion 56 rotates (arrow M4 in FIG. 10), and the first pressing portion 54 comes into contact with the end surface 73 of the head 29 of the linear motion member 11 and moves directly. Is pushed into the lock box 2 (arrow M5 in FIG. 10).

Referring also to FIG. 1, the linear motion member 11 pushed into the lock box 2 rotates the swinging member 12 that is swingably connected around the swinging shaft portion 34. The rotating swinging member 12 pushes the engaging portion 39 of the latch bolt 15 with which the claw portion 32 abuts against the front 17, and the latch bolt 15 resists the urging force of the compression spring 16 to lock the box 2. (Arrow M6 in FIG. 10).
With this series of operations, the strike (seat) attached to the door frame (wall side) is disengaged from the latch portion 37, and the door to which the push-pull lock 1 is attached can be opened. .

  When the operation of opening the door is finished and the pull-side handle 42 is opened, the pull-side handle 42 is rotated by the urging force of the compression springs 44 and 44 to return to the recess 45. The head 29 of the linear motion member 11 is no longer restricted by the first pressing portion 54, and the latch bolt 15 moves to the front 17 side by the urging force of the compression spring 16. The latch portion 37 protrudes from the latch hole 27 to the outside of the front 17. If the door is closed at this time, the latch part 37 will be latched by the strike attached to the door frame, and the door will be closed.

  In the push-pull lock 1, when the push-side handle 58 is pushed into the recess 60, the push-side pressing portion 59 integrated with the push-side handle 58 rotates, and the second pressing portion 67 causes the linear motion member 11 to move. Push into the lock box 2 (arrow M5 in FIG. 10). Push-pull lock from when the linear motion member 11 is pushed into the lock box 2 until the latch bolt 15 is pulled into the lock box 2 and until the door is closed and the door is closed again The operation 1 is the same as the operation when the pull handle 42 is operated.

Another method can be adopted by replacing the transmitting means for changing the reciprocating motion of the linear motion member 11 into the reciprocating motion of the latch bolt 15 whose direction is opposite to the swinging member. For example, both the linear motion member and the latch bolt are provided with a plurality of annular grooves arranged at equal intervals in the axial direction, and a gear that engages with any of the annular grooves is disposed between them to reciprocate the linear motion member. The latch bolt may be reciprocated in the reverse direction by the operation.

The “transmission member” in the present invention includes, in addition to the swinging member 12 having the above-described configuration, means for causing the latch bolt to reciprocate in the direction opposite to that of the linear motion member, like this gear.
The first pressing portion 54 and the second pressing portion 67 are moved not only in the direction in which the linear motion member 11 is pushed into the lock box 2 but also in the direction in which the linear motion member 11 that has been pushed out is pulled out from the lock box 2. be able to. For example, the first pressing portion 54 and the second pressing portion 67 are always engaged with the head of the linear motion member 11 to swing the first pressing portion 54 and the second pressing portion 67 and the reciprocating motion of the linear motion member 11. In this case, when the pull-side handle 42 is operated and the linear motion member 11 is pushed into the lock box 2, the push-side handle 58 is operated by the linear motion member 11. As a result, it is automatically pushed into the recess 60.

  As described above, when the first pressing portion 54 and the second pressing portion 67 are configured so that the swinging of the first pressing portion 54 and the second pressing portion 67 and the reciprocating motion of the linear motion member 11 are always performed in cooperation, the swinging member 12 causes the latch bolt 15 to move. These are preferably always engaged so that they are not only pushed out of the lock box 2 but also pulled into the lock box 2. As described above, the structure in which the swinging member 12 pulls the latch bolt 15 into the lock box 2 by swinging adopts a structure other than the structure in which the claw part 32 is brought into contact with the engaging part 39. be able to.

Instead of the compression spring 16 that urges the latch bolt 15 toward the outside of the front 17, a compression spring that urges the linear motion member 11 away from the front 17 is arranged between the linear motion member 11 and the front 17. May be. Further, the swing member 12 may be urged by a coil spring in a direction in which the claw portion 32 rotates toward the latch bolt support wall 19 side.
In addition, each structure in the push-pull lock 1, the lock box 2, the pull-side handle portion 3, and the push-side handle portion 4 or the overall structure, shape, dimensions, number, material, and the like are appropriately changed in accordance with the spirit of the present invention. be able to.

  The present invention can be used for push-pull locks used in residential doors and the like.
