0002

[Conventional technology]

In high-rise buildings, emergency entrances must be provided in the event of a disaster, etc. An external handle that can be unlocked from the outside is required. And in recent years, this external hand In addition to being easy to unlock when entering the building, it is also required that the door be unobtrusive in appearance. is high.

0003 However, on the other hand, the design of sashes, which are used as window frame materials, is important, so the shape (pressure) (e.g. cross-sectional shapes created by extrusion molding) are becoming more complex and smaller, and the original external handle Depending on the specifications of the dollar, it is no longer easy to install.

0004 Therefore, it is preferable for the structure of the external handle to be directly connected to the internal handle. However, it requires multiple gears or takes up relatively little space. It is made more compact by adopting a lever structure, etc.

[0005]

[Problem that the idea aims to solve]

Traditional external handles can be installed inconspicuously on complex and small sashes. Therefore, efforts are being made to make it more compact by using multiple gears. however Depending on the shape of the sash, the number of gears used increases, making the structure complex and making it difficult to operate. Since the actuation force is transmitted through multiple gears, a large unlocking force is required, resulting in poor operability. There was a risk that it would decline.

[0006] This invention was developed in view of the above situation, and has a simple structure that can be stored in a small space. It provides an external handle that is visually unobtrusive and easy to operate. The purpose is to ensure design quality and improve operability.

[0007]

[Means to solve the problem]

The structure of the external handle according to the present invention to achieve the above object is based on the sash. The base shaft is rotatably supported via the base shaft, and an insertion hole is formed in the end face of the base shaft. a dollar, which is coaxial with the base axis of the inner handle and is attached to the sash through a pedestal; is rotatably supported and slidably supported in the axial direction, and can be loosely fitted into the insertion hole at one end. A shaft on which a prismatic engagement part is formed and a handle of an external handle is formed on the other end. and fixed to the outer periphery of the inner handle on the end face side of the base shaft and connected to the locking mechanism. a gear, and the engaging portion is inserted by sliding in the axial direction of the shaft that is fixed to the gear. It is characterized by comprising a connecting member in which a square hole is formed to be in an engaged state.

[0008]

[Effect]

Under normal conditions, the engaging part of the shaft is inserted into the insertion hole of the internal handle, and the internal handle is inserted into the insertion hole of the internal handle. When rotated, the insertion hole idles around the outer periphery of the engaging part, and rotation is not transmitted to the shaft. Also, the rotation of the internal handle is not restricted, and solutions using only the internal handle are possible. Lock operation becomes possible. On the other hand, when unlocking from the outside, the handle is pulled. As the shaft moves in the direction away from the internal handle and the engaging part is removed from the insertion hole, , is inserted into the square hole of the connecting member and engaged. The handle is pivoted when the engaging part is engaged with the square hole. When the handle is rotated, the rotation of the handle is transmitted to the gear through the connecting member, and the handle is When the lock is directly connected to the gear, unlocking is performed using the gear.
