Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a latch which is unlocked by pushing or pulling a handle in an opening direction.
The present invention relates to a so-called push-pull type handle lock in which the door is opened by continuing the operation as it is.

[0002]

2. Description of the Related Art The above-mentioned handle lock opens a door in connection with a handle operation for unlocking a latch lock.
It is very easy to use, and is widely used, for example, as entrance doors for apartment houses such as detached houses and condominiums, and as entrance doors for offices.

In a multi-family house such as a detached house or an apartment,
In some cases, the entrance door may be installed inside the door, but in consideration of expanding the living space, the entrance door is often installed outside, and in offices, etc. From the above point of view and the viewpoint of streamlining work,
The entrance door is often provided inward.

If, for example, a handle lock for an outside opening door is to be used for an inside opening door, a pulling handle, that is, a handle on the outside, and a handle on the pushing side, that is, a handle on the inside, are used. Must be attached to the outside of the room, but in this case, the following inconveniences occur in terms of security. That is, the mounting screw of the seat for attaching the handle of the handle lock to the door surface inside and outside the door is generally exposed to the seat inside the door, and if this seat inside the door is used outside the room,
Anyone from the outside can remove the seat by removing the mounting screw, and anyone can unlock and open the door freely.

[0005]

For these reasons,
Conventionally, it was necessary to manufacture two types of handle locks corresponding to an outward opening door and an inward opening door, respectively. Accordingly, not only the manufacturing cost but also the manufacturing cost including the management cost has become extremely high.

[0006] Further, depending on the type of door to which the mounting position of the handle lock is limited or the user's preference (design surface, operability, etc.), there are cases where the handle is mounted vertically on the door surface and cases where it is mounted horizontally. In order to be able to cope with the above, two more types of handle locks for vertical and horizontal use were required, and the handle locks for vertical and horizontal use were built into the lock case and lock case. In a broad sense that includes a lock body and a handle made of a lock mechanism component, there is no compatibility between the lock body and the handle at all, which significantly increases the manufacturing cost and significantly There was a problem.

The present invention has been made to solve the above-mentioned conventional drawbacks, and is intended to be used for both an outward opening door and an inner opening door by using a single kind of handle lock. Further, the handle lock can be used for both the vertical handle and the horizontal handle.

However, in the case of such a configuration, means (two vertical sets) for releasing the locking pieces b, b of the pair of locking pieces 22, 22 from the locking grooves a, a of the latch bolt 16 are provided. The operation members 27a, 27b, 28a, 28b for the direction handle and the sideways handle, and the interlocking members 43A, 43B) are slightly complicated in configuration.

On the other hand, with the structure shown in FIGS. 3 and 4, as described with reference to FIGS.
The actuating members 45a, 45b are rotated in the same direction by either pushing operation or pulling operation of the handles 11a, 11b, so that the locking pieces b, b are released from the locking grooves a, (the operating member). 27 and 28 and the interlocking member 43) can be greatly simplified, and the configuration of the latch lock 9 is simplified, so that there is an effect that a significant cost reduction is achieved.

When the handle lock 4 which can be used for both the inward opening type and the outward opening type is formed exclusively for the vertical handle, the operation member 28 for the horizontal handle is unnecessary, and the exclusive use is made only for the horizontal handle. In this case, it is needless to say that the operation member 22 for the vertical handle is unnecessary, and the simplification and cost reduction of the latch lock 9 can be achieved.

Further, the handle lock 4 according to the embodiment is provided with the final lock including the dead bolt 8, the cylinder 5, the thumb turn 7, and the like, but is provided with only the genuine latch lock 9 having no final lock. The handle lock 4 can be applied to the present invention.

The latch lock 9 has been described as a so-called reversing latch type. However, the latch lock 9 has a structure that does not reverse and a structure in which the latch bolt 16 is directly retracted with the rotation of the operating members 45a and 45b. Can also be used.
