Abstract

PROBLEM TO BE SOLVED: To lock and unlock a door by either operation of sway and parallel movement of a handle by providing vertically long handles on an opening/closing door having a latch lock, and pulling down an operation plate by a vertical L-shaped link. SOLUTION: A latch lock 2 is embedded on the releasing end side of a door 1, and vertically long handles 3, 3A are attached to the inner and outer faces of the door 1. When the center part of the handle 3 is pulled in a door closed state, upper and lower L-shaped link 41 are rotated against urging of a spring 43 by centering a pin 42 through a connection member 31, an operation plate 2A is pulled down to rotate the hub of the latch lock 2 so as to be unlocked, and the door can be opened. In the case where the upper part or the lower part of the handle 3 is drawn, the handle 3 is swayed, only one link 41 is rotated, and the other link 41 is loosely fitted to the fitting hole of the operation plate 2A. Unlocking and door opening can be also performed by pushing the handle 3A. Thus, the door can be unlocked and opened by either operation of sway and parallel movement of the handles 3, 3A.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called push-pull having a vertically or horizontally long handle, in which a latch is unlocked by an operation of pulling or pushing a door in an opening direction and a door is opened by one-touch operation as it is. The present invention relates to a handle device for a pull-type door lock.

[0002]

2. Description of the Related Art As a conventionally known handle device of this type,
Japanese Unexamined Patent Publication No. Hei 8-26379 discloses a handle swing type in which one end of a handle is pivotally supported.
There are two types of handle parallel movement type using a parallel link mechanism having a handle as an element as disclosed in Japanese Patent No. 0772.

[0003]

In the handle swing type handle device in which one end of the handle is pivotally supported, one end of the handle is pivotally supported when the handle is operated. Because the handle cannot be swung even when pushed or pulled, there is a problem that infants and elderly people are confused about which part to push or pull, and also the part near the pivot. When the is operated, there is a problem that an extremely large force is required to unlock and open the door.

[0004] In the latter handle-translation type handle device using a parallel link mechanism having a handle as an element, the handle is pushed or pulled in parallel with the upper or lower piece of a parallelogram forming a parallel link. As long as you operate any part of the handle, it has the advantage that it can be unlocked smoothly and the door can be opened as it is, and if you push or pull any part like the former There is no problem that it is good or confusing, but the direction other than the direction parallel to the upper or lower piece of the parallelogram that forms a parallel link when pushing or pulling a part other than the center of the handle suddenly When pushing or pulling to the side, the bias of the point of action of the force applied to the link mechanism may cause the parallelogram to be broken, and excessive force may be applied to the pivot, or the link mechanism may become unstable. Handle not smoothly translation, there may not be unlocked.

In general, this kind of push-pull type handle device is invented for the purpose of opening the door as it is by pushing or pulling the handle in the opening direction, and unlocking the door lock. Since this is only a part of the process, the person who wants to operate the handle usually operates with a large force to open the door from the beginning, and it can not be unlocked as described above When this occurs, a large impact force is applied to the link mechanism and the latch lock of the handle, and the link mechanism and the latch lock are damaged, and in the worst case, the arm and the wrist are damaged.

Further, in the handle translation type handle device using the parallel link mechanism having the handle as an element, a long link for connecting the operating portion of the handle is required for each of the handles inside and outside the door. Therefore, there is also a problem that the number of parts increases and the manufacturing cost including the connection work becomes high.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention employs a novel mechanism which is neither a conventional swing type nor a parallel translation type of a handle. Even if the operation is a sudden operation,
It is an object of the present invention to provide a door lock handle device that can be smoothly unlocked and opened even if the operation is performed from any direction without being limited to a certain direction. Things.

[0008]

A handle device according to the present invention comprises a pair of seats for vertically or horizontally mounting a handle on each door surface inside and outside a door, and a handle supported between the two seats. A handle device for a door lock, wherein the door lock is provided with an operation plate that allows the latch bolt to retreat or retreat by moving vertically or horizontally,
At both ends of the handle, a pair of connecting members are provided, which are pivotally connected to links rotatably supported inside the two seats, respectively. An operating portion for moving in the unlocking direction is provided.

[0009]

Since both ends of the handle are pivotally supported on the links of the seat, respectively, the handle can be escaped by the pivot, so that if the center of the handle is operated, the handle is translated as it is. If you operate other than the center, one end becomes a fulcrum and the bias of the handle moving once while swinging is escaped by rotation at the pivot, and the handle is pushed or pulled suddenly or diagonally instead of horizontal. The door can be unlocked and opened smoothly even when pushed or pulled from.
