Description

[Detailed description of the invention] In order to enable opening from the outside in the event of an emergency such as a fire entrance, the external handle is connected to the internal handle via a shaft installed on the internal handle. Regarding improvements to the internal and external interlocking handles.

Conventional internal/external interlocking handles of this type simply had two handles installed on the inside and outside of the sash and connected, so when the normally used internal handle was rotated, the external handle also rotated. This is unfavorable in terms of appearance, and the glass plate of the inner shoji screen obstructs the rotation of the outer handle, especially in single-swing sashes and sliding sashes, so the inner and outer handles must be installed with their orientations 180 degrees apart from each other. However, there were drawbacks such as spoiling the aesthetic appearance.

The present invention overcomes the above-mentioned drawbacks of the prior art, and therefore, the purpose of the present invention is to provide an interior and exterior that is favorable in appearance and convenient in handling, by preventing the external handle from operating even when the internal handle is rotated. It is to provide an interlocking handle.

In order to achieve the above object, the feature of the internal and external interlocking handle according to the present invention is that the shaft installed in the internal handle passes through the boss part of the external handle and is rotatable. This causes a pin disposed within the outer handle to engage a recess in the shaft, whereby the outer handle and the shaft are pivotally connected together.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a single-pull sash equipped with an internal and external interlocking handle 1 according to the present invention, and the sash 2 of the sash can be moved to either the left or right.
Handles 1 are provided on both sides thereof. 2 and 3 show an embodiment of the present invention in detail, in which numeral 11 is an internal handle, and 12 is a rotating top that follows the operation of the internal handle. 13 is an external handle, 14 is a handle of the external handle 13, and a pin 1 is provided inside thereof so as to be slidable in the axial direction of the handle.
5 is provided. The pin 15 has an elastic member, preferably a coil spring 1, at one end, as shown in FIG.
6 receives elasticity and is pressed. Reference numeral 17 denotes a set rod, which passes through the pin 15 and is provided in the elongated hole 14a of the handle 14 of the external handle with enough room to allow some movement in the axial direction. Reference numeral 18 denotes a shaft installed to rotate together with the rotating top 12, and a square core 18a located at one end thereof.
is fitted into the square hole 12a of the rotating top 12.
19 is a base of the external handle 13, and the base has a protrusion 19a with which the tip of the setting rod 17 engages.
When the external handle 13 is rotated through a predetermined angle, the tip of the setting rod 17 comes off the protrusion 19a, so that the inner periphery of the protrusion is partially straight as shown in FIG. It is preferable that the outer periphery has an arcuate shape for the reasons described below.

As shown in FIGS. 6 and 7, an arcuate groove 13b is formed in the boss portion 13a of the external handle 13, and the groove 13b is preferably semicircular as shown. Further, as shown in FIG. 8, the outer end 18b of the shaft 18 is shaped like a disk with a slightly larger diameter than the main body, and a recess 18c is formed at an appropriate position on the outer periphery. The shape of this recess may be any suitable shape such as a circular arc, but as shown in the figure,
Preferably, it is a shaped groove. As seen in FIGS. 3 and 4, the outer end 18b of the shaft is pivotally engaged in the groove 13b of the outer handle. The shaft 18 is provided with a retaining member 18d that engages with the protrusion of the base 19. The handle 13 is installed by having its boss portion 13a set on a base 19 via a shaft 18, and the base 19 being fixed to a sash member with screws or the like.

In normal operation, even if the internal handle 11 is rotated, both the rotating top 12 and the shaft 18 rotate, but the shaft 1
The outer periphery of the outer end 18b of 8 is the groove 13 of the outer handle.
b, and the external handle 13 does not rotate.

When unlocking from the outside in an emergency, for example, by rotating the handle 14 of the external handle by a predetermined angle, preferably 180 degrees, in the direction A in FIG. Since the pin 15 is always pressed against the outer end 18b of the shaft by the elasticity of the spring 16, the tip of the pin 15 fits into the recess 18c of the shaft 18. At this time, the setting rod 17 is also moved in the axial direction of the handle 14 together with the pin 15. The pin 15 thereby connects the external handle 13 to the shaft 18 . Next, when the handle 14 is rotated in the opposite direction (direction B in FIG. 4), the shaft 18 is also rotated, and at the same time, the internal handle 11 is also rotated via the rotary piece 12, so that the lock is released. Note that when the set rod 17 is returned to its original position in the axial direction of the handle 14, the tip of the set rod 17 slides on the outer periphery of the protrusion 19a and is locked at a predetermined position on the protrusion, causing the outer handle to move relative to the inner handle. becomes free. If the outer circumference of the protrusion 19a is an arc, the set rod 1
The tip of No. 7 can easily slide. In the above embodiment, the tip of the setting rod 17 is locked by the protrusion 19a, but it is clear that such a locking part may be a notch, a groove, or the like.

As described above, according to the present invention, the lock can be unlocked by an extremely simple operation of the external handle, and the external handle does not rotate when the internal handle is normally operated, so the external handle and internal handle are intersected by 180 degrees. There is no need to set it up differently. Therefore, it is convenient to handle and has a favorable appearance.
