Description

  The present invention relates to a door handle for a push-pull lock that can be easily opened and closed even when a hand or eye is inconvenient.

In recent years, Japan has become an aging society, and various ideas have been made inside the house to protect the elderly.

  For example, in the case of an elderly person, a situation occurs in which a person kicks and falls while walking indoors, and in order to solve this situation, there are houses on the market in which there are as few steps as possible in the room.

  By the way, some elderly people find it difficult even to grab the handle and turn it, and there are also people who cannot move even their handles because their fingers do not move. On the other hand, in the case of a blind person, even if it is possible to go to a place with a door, there are cases where it is difficult to operate the handle (for example, Patent Document 1).

  In the case of these people, for example, when a disaster such as a fire occurs, the worst situation that it is impossible to escape to the outside alone can occur. The same applies not only to elderly people but also to people who are handicapped.

Therefore, the construction industry and the elderly are awaiting the development of a door handle for a push-pull lock that can be opened and closed smoothly even if there are inconvenient parts in the hands and eyes.
